Power manipulator structure and composition
The structure and composition of the power manipulator system.
Assist manipulator load shifting system is usually composed of moving and sliding part, assist manipulator host body, special fixture, gas supply system and air route control system. The roles of each part are as follows:
1, mobile and sliding part: in order to make the power manipulator has a greater range of service, power manipulator body is usually installed on the sliding track or platform car, in order to facilitate the workpiece in different positions. Usually, the layout of the sliding track is arranged in a well shape, in which two fixed hanging on the foundation, the other one is active, and the manipulator is suspended under the active track. The movement of the movable track and the power manipulator is usually pulled by manpower. There is no special restriction on the length of the two fixed tracks. The shorter the better the movable track should be considered in the design, based on the consideration of the fixed length of the track and the convenience of moving. The longest active track should not exceed 6M. The platform car has two forms of walking on the ground and hanging in the air. The platform trolley walking on the ground is installed with casters and supporting feet, which are moved by manpower. The workpiece is not allowed to be suspended during the movement. After moving to the operating position, the supporting feet must be put down to operate. Aerial hanging walking has human walking and electric walking, walking does not affect the power of the manipulator's own operation.
2, power manipulator main body: power manipulator main body according to the structure is divided into soft cable type and hard arm type 2 categories. Soft cable type fuel manipulator is usually used with sliding track, its characteristic is the service scope is larger, compared with other fuel manipulator, lighter, flexible use, the disadvantage is that there are obstacles between power manipulator and the workpiece is not convenient to use, as well as to the operation of the workers' proficiency requirements higher (think of the feeling of when we started learning to ride a bicycle). Note: Customers will often questioned its operation stability problems, they have put forward questions usually in the use of the gourd as reference, you can imagine, the gourd is usually at the top of the ontology, the following artifacts are hanging by follow-up, because of the connection between the ontology and the workpiece is flexible, plus workers usually one-handed supporting artifacts, Therefore, there will be a phenomenon of workpiece shaking when moving. And power transfer system of manipulator is pulled by manpower, the ontology is accompanying with the following artifacts, and workers are usually hands operating workpiece, so it is soft cable connection, also won't appear the phenomenon of shaking, hard power structure of the manipulator arm type is more rigid arm by several groups of rotary joints into an organic whole, implementation to take place in a circular area application of artifacts, Its characteristic is easier to achieve precise balance, as well as to the operation of the artifacts are very complex, and can also be very convenient to avoid obstacles, such as customer requirements within the scope of a smaller diameter (3.5 m) take place when the workpiece, can directly use columns or hangs fixed installation form of foundation type, if you need the larger scope of services, and mobile platforms used car.
3, special fixture: it is one of the most core part of the whole power manipulator system, the system is mainly decided by the stand or fall of fixture design is whether it is good, it is completely according to the requirements of the customers to use technology and state of workpiece and special custom, so it is a kind of non-standard design, our engineers at ordinary times the main work is concentrated in this part, must let the customer know 2 points: Firstly, if you can produce good jig, does not depend on the size of the company, also does not depend on the stand or fall of processing equipment, and the engineer's title, but depends on whether has enough in power manipulator can design and manufacture experience and convenient many face-to-face communication with customer engineers, in order to accurately understand the customer's demand and use of environmental conditions, Because the power manipulator system is a non-standard equipment, before the customer to buy, it is difficult to see the same prototype, they actually buy is a scheme or concept, can be a good design and production of the concept of the customer needs equipment, depends on the front of the 2. Second, power manipulator equipment is not universal, in simple terms, it is just a power tool, the standard to judge it is good or bad should be, whether it can better meet most of the workpiece most of the operation. As a special fixture, as far as possible can be used for special purposes, such as thinking too much use, inevitably lead to jig is too complex and cumbersome, and affect the operation, for example, ping said Swiss army knife while there are many USES, it can be used to cut food, but definitely not a kitchen knife to use, also can kill pig, but certainly not kill pig knife, therefore, in the future to communicate with the customer, Must understand in detail the customer needs to help the manipulator, what is mainly used to do? Special fixture according to the different structure form, can be roughly divided into the following categories: hook type, clamping translation type, adsorption translation type, clamping turnover type and adsorption turnover type, etc.
4, gas supply system: usually by gas supply two parts (filter and pressure reducing valve "stable use") and pipeline composition, according to the special requirements of customers, can also increase the supercharger and gas storage tank. The air supply pipe is usually made of coated wire rope and customized spiral air supply pipe
Yes, when the moving part of the pipeline is long (greater than 10m) or needs to pass through a bend rail, or cables need to be moved together
The installation mode of rubber hose and guide cable block is adopted.
5, pneumatic control: whether the use of different requirements and assist manipulator form of ontology, the configuration of different operating systems, can be divided into the host body control and fixture action control two parts, the two parts are not independent respectively, but the pipe connected to control each other, in order to realize all kinds of protection of the state and control automatic switch.
