Robot clamp shared by various cylinder covers

Abstract

The invention discloses a robot clamp shared by various cylinder covers. The robot clamp comprised a clamp main body frame, a clamping assembly and a detecting assembly , wherein the clamp main body frame is fixedly disposed on a robot arm; the clamping assembly comprises at least one group of clamping jaws which are pairwise symmetrical, and a clamping jaw linear driving mechanism, the clamping jaws are in sliding fit with the clamp main body frame through a sliding table which is fixedly disposed on the clamp main body frame, and the clamping jaw linear driving mechanism forces the clampingjaws to switch between a clamping station and a releasing station; the detecting assembly comprises a plurality of cushion blocks which are fixedly disposed on the bottom surface of the clamp main body frame, the cushion blocks are provided with blowing holes, the bottom surfaces of the cushion blocks are provided with attachment surfaces, outlets of the blowing holes are exposed out of the attachment surfaces, the attachment surfaces are attached to the cylinder cover surfaces of the cylinder covers during clamping, the blowing holes communicate with a compressed air source through a pipeline, and air pressure detecting elements are connected into the pipeline in series; and the two clamping jaws of each group are arranged in a face-to-face mode, the clamping jaws are provided with hook-shaped portions, and the hook-shaped portions are located below the cylinder cover surfaces. The clamp is light, positioning of the clamp and workpieces are accurate, grabbing is firm and reliable, loosening is not prone to occurring, and the universality is good.

Description

technical field [0001] The invention belongs to the technical field of cylinder head clamps, and in particular relates to a common clamp for multi-type cylinder heads used by robots. Background technique [0002] In the machining and assembly production process of automobile engines, using robots to grab cylinder heads for operation is a process often seen in modern automated assembly lines, such as robots grabbing castings to polish flash, robots assist machining, loading and unloading, and cleaning It is very suitable to use robots to complete repetitive monotonous and high-precision tasks such as removal of processing burrs, assembly line handling of cylinder head loading and unloading, and line transfer. [0003] The robot fixture is an indispensable tooling in the process of manipulating the workpiece by the robot holder, and it is an extended 'handle' for the general robot to operate the specific workpiece. A good fixture is an important guarantee for stable work. Gen...

Problems solved by technology

[0004] However, at present, the clamps used by robots to grab the cylinder head are mostly welded steel structures, which are heavy, and some even exceed the weight of the workpiece to be grabbed. The work load of the robot is bound to increase, and even a robot with a stronger working ability has to be selected.

[0005] In addition, the traditional cylinder head fixtures for robots are poor in versatility, and often the 3-cylinder and 4-cylinder machines cannot be used universally, and the corresponding fixtures need to be replaced when replacing products

Since there are usually sensors and clamping cylinders on the fixture, there must be electricity and gas connections on the fixture. In order to reduce the trouble of re-connecting electricity and gas when changing the fixture, the existing robot arm is usually equipped with a transition gun change disk , to be connected in series between the robot and the fixture through a special gun changer mechanism. Although the problem of quick fixture change by the mechanical arm is solved, the addition of the transitional gun changer method inevitably increases the robot’s workload on the basis of the original fixture. , the requirements for robots will further increase
