[0008] The above technical purpose of the present utility model is achieved through the following technical solutions: a tool for processing the front cover of a vehicle air-conditioning compressor, comprising a processing table and a front cover casting arranged on the processing table, a processing device is provided at a position corresponding to the front cover casting on the processing table, a fixing part for fixing the front cover casting is provided on the processing table, a rotating part for driving the front cover casting to rotate is provided at a position corresponding to the fixing part on the processing table, the rotating part is used to drive the front cover casting to rotate intermittently on the processing table, the processing equipment comprises a first processing equipment and a second processing equipment, the first processing equipment is provided above the front cover casting, and the second processing equipment is provided in two groups and is symmetrically arranged on both sides of the front cover casting.

[0009] By adopting the above technical solution, the staff fixes the front end casting through the fixing part, and the fixing part drives the front cover casting to rotate intermittently on the processing table through the action of the rotating part, and aligns the position of the front cover casting with the first processing equipment according to the position of the mounting hole that needs to be opened on the front cover casting, and then closes the rotating part so that the rotating part no longer drives the fixing part and the front cover casting to rotate. At this time, the first processing equipment can process the mounting holes on the upper end face of the front cover casting, and the mounting holes on the side surfaces of the two ends of the front cover casting can be processed by the second processing equipment, and the processing head of the second processing equipment can be connected to the processing bracket through a threaded connection, which is convenient for replacing the second processing equipment with different apertures, making the second processing equipment more applicable. At the same time, with the action of the rotating part, the front end casting rotates on the processing table, and the second processing equipment is driven to process the front end casting according to the number of mounting holes that need to be opened on the side surface of the front end casting. The front end casting does not need to replace other tooling or other processing equipment to realize the gradual processing operation of the front end, thereby improving the efficiency of the front end casting processing.

[0010] The utility model is further configured as follows: the fixing member includes a fixing platform for fixing the front cover casting and a boss protruding from the fixing platform, and the boss is engaged with an inner cavity provided in the front cover casting.

[0011] By adopting the above technical solution, when the front end casting is fixed on the fixed platform, the front end casting contacts the boss and the boss is tightly inserted into the inner cavity opened in the front end casting, thereby achieving close contact between the boss and the front end casting and fixing the front end casting. In this way, the stability of the front end casting when it is fixed can be ensured and it can rotate with the rotation of the fixed platform.

[0012] The utility model is further configured as follows: a plurality of recessed grooves are provided on the outer wall of the boss, and the plurality of recessed grooves form an anti-slip structure.

Each time the toggle block rotates in and out of the slot, it can drive the groove wheel disc and the fixed table to rotate an angle, and the front end casting on the fixed table will rotate to the position where the next mounting hole needs to be processed. After the groove wheel disc rotates a full circle, the mounting holes at various positions on the upper surface of the front end casting have been completed, and the mounting holes on the side of the front end casting have also been completed. There is no need for the staff to change tooling or processing equipment, which is convenient for the staff to process the front end casting, thereby improving the processing efficiency of the front cover of the automotive air-conditioning compressor.

[0016] The utility model is further configured such that: the number of the plurality of notches is consistent with the number of mounting holes machined on the upper surface of the front end casting.

[0017] By adopting the above technical solution, each time the toggle block rotates into and out of the slot, it can drive the groove pulley and the fixed platform to rotate by an angle, so that the position on the front end casting on the fixed platform that needs to be installed is also rotated by an angle. The mounting holes on the front end casting that need to be surface-processed are aligned with the first processing equipment for processing, and after the groove pulley rotates a complete circle, all the mounting holes on the front end casting are completed, and there is no need to replace other tooling or equipment.

At this time, the convex arc surface and the concave arc surface will rotate to a fit state, and the groove wheel disk and the fixed platform will no longer rotate without the driving force of the toggle block, and the staff can also turn off the motor at this time, making the groove wheel disk and the toggle disk more stable, and ensuring the stability of the groove wheel disk and the fixed platform when they stop rotating.

[0020] The utility model is further configured as follows: the toggle block is configured as a cylinder.

[0021] By adopting the above technical solution, the toggle block arranged in a cylindrical shape will not get stuck in the groove wheel when rotating in and out of the groove wheel, making the toggle block rotate in and out of the groove wheel smoother.

[0022] The utility model is further configured as follows: an annular groove for sliding the toggle block is provided on the processing table, and a trajectory of the annular groove is consistent with a rotation trajectory of the toggle block.
