Description

Mechanical arm

Technical Field

The utility model belongs to robot arm field, concretely relates to manipulator.

Background

With the improvement of the living standard of people and the rapid development of the automobile industry, in order to meet the vigorous demand of automobiles, automobile manufacturers and suppliers continuously improve the production efficiency while ensuring the installation performance.

The valve connector is a common mechanical product in the automobile industry, is widely used in the automobile industry, and is often required to move different original pieces to an assembly station for assembly in the production and manufacturing process of the valve connector.

Disclosure of Invention

For solving the technical problem that above-mentioned valve connector packaging efficiency is low, the finished product percent of pass is low, the utility model provides a manipulator, original paper to appointed station that can the automatic removal valve connector, and fix a position accurate to improve the packaging efficiency, improve the finished product qualification rate.

Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a manipulator, includes the arm the forearm top of arm is provided with the control unit the main shaft lower extreme of arm is provided with anchor clamps subassembly, the control unit includes mounting bracket and two solenoid valves of setting on the mounting bracket, anchor clamps subassembly includes that the cover is established at the main epaxial stopper of arm and connecting block from the top down in proper order the below of connecting block is provided with two parallel clamp cylinders side by side, and two parallel clamp cylinders are controlled by the solenoid valve that corresponds respectively install mechanical fixture part and lower mechanical fixture part on the last clamping jaw and the lower clamping jaw of parallel clamp cylinder respectively, go up mechanical fixture part and lower mechanical fixture part and can be close to each other or keep away from under the drive of the parallel clamp cylinder that corresponds.

Preferably, the two electromagnetic valves are overlapped one on top of the other. By adopting the structure, the circuit arrangement is facilitated.

Preferably, a muffler is provided at an exhaust port of the solenoid valve. By adopting the structure, the noise generated by the exhaust of the electromagnetic valve can be reduced.

The utility model has the advantages that: the original paper that can once only remove two valve connectors has improved production efficiency greatly, and the location is accurate during the removal, effectively improves the finished product qualification rate.

Detailed Description

The invention will be further described by way of examples with reference to the accompanying drawings:

as shown in fig. 1, a manipulator mainly comprises a manipulator 1, a control unit 2 and a clamp assembly, wherein the manipulator 1 adopts a selective compliance assembly manipulator which is most suitable for plane positioning and assembly operation in the vertical direction, the control unit 2 is arranged at one end, close to a large arm, above a small arm of the manipulator 1, the clamp assembly is arranged at the lower end of a main shaft of the manipulator 1, and the control unit 2 is used for controlling the clamp assembly to enable the clamp assembly to clamp or put down a valve connector.

As shown in fig. 1, the control unit 2 includes a mounting rack 201 and two electromagnetic valves 202 disposed on the mounting rack 201, the mounting rack includes a plurality of supporting members 201a and a mounting plate 201b horizontally mounted on the supporting members, and the two electromagnetic valves 202 are mounted on top of each other in an overlapping manner, which facilitates the wiring arrangement. A muffler 8 is provided at the exhaust port of the electromagnetic valve 202 to reduce noise generated by exhaust.

As shown in fig. 1, the clamp assembly comprises a limiting block 3 and a connecting block 4 which are sequentially sleeved on a main shaft of the mechanical arm 1 from top to bottom, two parallel clamping cylinders 5 are arranged below the connecting block 4 side by side, each parallel clamping cylinder 5 is provided with two air connectors 501, the clamping jaws of the two parallel clamping cylinders 5 are in the same orientation and can only move up and down, the two parallel clamping cylinders 5 are respectively controlled by corresponding electromagnetic valves 202, an upper mechanical clamp part 6 and a lower mechanical clamp part 7 are respectively arranged on the upper clamping jaw and the lower clamping jaw of the parallel clamping cylinder 5, the upper mechanical clamp part 6 is in an "L" shape, the horizontal section of the upper mechanical clamp part is fixed above the upper clamping jaw of the parallel clamping cylinder 5, the vertical section of the upper mechanical clamp part extends downwards from the outer end of the horizontal section, the lower mechanical clamp part 7 is in an "L" shape, the horizontal section of the lower mechanical clamp part is fixed below the lower clamping jaw of the, the outside of the vertical section of last mechanical fixture part 6 and lower mechanical fixture part 7 all is provided with the limit structure who suits with the original paper of valve connector, can prevent that the original paper of the valve connector of pressing from both sides from dropping, goes up mechanical fixture part 6 and lower mechanical fixture part 7 and can be close to each other or keep away from under the parallel drive of pressing from both sides cylinder 5 that corresponds, realizes pressing from both sides the original paper of getting or loosening the valve connector.
