[0002] The automobile pump cover is made of steel or aluminum through casting. Since the surface of the casting is relatively rough and the precision is low, after the casting is completed, the automobile pump cover needs to be processed by machine tools to produce the structure required by the design, such as bolt holes, specific mounting surfaces, etc. Our company uses CNC milling machines to process it. The traditional clamping method is to use a vise or bolts with a pressure plate to clamp it and position it on the machine tool workbench. Each time it is clamped, the worker loosens or tightens the vise, bolts, etc. The operation is cumbersome and it will take more time to unload and load the material. This makes it difficult to effectively improve the processing efficiency. Summary of the invention

[0024] Combination Figure 1-4 As shown, the present application discloses a tooling for processing automobile pump covers, which is fixed on a machine tool working platform 10, and specifically includes an adapter plate 20; a plurality of air ducts 21 and mounting holes are provided on the adapter plate 20, one end of the air duct 21 is connected to a pressure air source (air compressor outlet) through a pipeline, and the other end is exposed on the upper end surface of the adapter plate (20); a part of the mounting hole is used to connect to the machine tool working platform 10 through bolts, and the other part is a threaded hole, which is used for connecting the upper end parts to it with bolts.

[0025] It also includes a plurality of pneumatic clamping assemblies 30, of which two are provided in the present embodiment, and they are adaptively increased or decreased according to the actual cutting force and the size of the workpiece. Each pneumatic clamping assembly 30 includes a cylinder 31, a pressure head 32, a support seat 33 and a connecting rod 34; the cylinder 31 is fixed on the adapter plate 20; the cylinder 31 is fixed on the adapter plate 20 by bolts 36, and the air passage 21 is connected with the gas flow passage of the cylinder 31 (it should be noted that seals are provided between the bottom surface 31a of the cylinder 31 and the adapter plate 20, and between the air passage 21 and the gas flow passage of the cylinder 31 to avoid air leakage at the connection; for example, a sealing ring is provided); the piston rod 313 of the cylinder 31 is hinged to one end of the pressure head 32, the support seat 33 is fixed on the cylinder 31, and one end of the connecting rod 34 is hinged to the support seat 33, and the other end is hinged to the middle of the pressure head 32; specifically, see Figure 2 As shown, the air channel 21 includes a first air channel 21a and a second air channel 21b (it should be noted that the first air channel 21a and the second air channel 21b are processed into horizontal and vertical holes on the adapter plate by deep hole drilling and other equipment, thereby forming corresponding air channels after being connected); the cylinder body of the cylinder 31 is hollow to form a piston cavity 311, and the piston 312 is located in the piston cavity 311. One end of the piston rod 313 is connected to the upper end of the piston 312, and the other end passes through the cylinder body and is hinged to the lower end 321 of the pressure head 32. The upper end 322 of the pressure head 32 contacts the automobile pump cover after being pressed; one end of the gas flow channel 31b of the cylinder body is connected to the first air channel 21a, and the other end is connected to the piston chamber 311 located above the piston 312; the lower end of the piston chamber 311 is open to the outside, so that after the cylinder is fixedly installed on the adapter plate 20, the piston chamber 311 is directly connected to the second air channel 21b, so that after the cylinder is fixedly installed on the adapter plate 20, the piston chamber 311 located below the piston 312 is connected to the second air channel 21b. Therefore, when the solenoid valve is switched to allow air to enter the first air passage 21a and the second air passage 21b is connected to the atmosphere, the piston 312 moves downward and the pressure head 32 rotates and lifts clockwise, thereby releasing the automobile pump cover 50. At this time, the automobile pump cover 50 can be removed, and the surface of the tooling can be blown with an air gun, and a new automobile pump cover can be inserted; the switch is controlled to allow the first air passage 21a to be connected to the atmosphere and the second air passage 21b to enter. At this time, the piston moves upward and the pressure head is pushed by the piston rod to rotate counterclockwise and press on the automobile pump cover 50. The clamping is completed and the machine tool is started for processing.

[0026] A plurality of positioning components 40, preferably two in this embodiment, are located below the automobile pump cover 50; including a positioning seat 41, the positioning seat 41 is fixedly mounted on the adapter plate 20, and a positioning column 411 is provided on the end face of the positioning seat 41 facing away from the adapter plate 20; in the process of installing a new automobile pump cover, in order to facilitate the rapid positioning of the automobile pump cover, it is necessary to adjust the position of the automobile pump cover so that the positioning column 41 is inserted into the positioning hole 51 of the automobile pump cover. The positioning column 411 is inserted into the positioning hole 51 of the automobile pump cover 50, and the cylinder 31 pushes the pressure head 32 to rotate counterclockwise and presses it tightly on the automobile pump cover 50, thereby completing the clamping.

[0027] Further preferably, in order to make the automobile pump cover support more stable, the positioning assembly 40 of this embodiment preferably also includes a support seat 42, the support seat 42 is fixed on the adapter plate 20, and a raised support block 421 is provided on the end surface of the support seat 42 away from the adapter plate 20. The raised support block 421 contacts the corner or support point of the automobile pump cover, and the raised support block 421 ensures contact with the automobile pump cover while avoiding interference with other positions of the automobile pump cover. It is further preferred that the positioning column 411 includes a tapered section 411a, so that the positioning hole of the automobile pump cover can be smoothly inserted into the tapered section 411a and realize self-centering; at the same time, in order to ensure that it can be located in the same plane with the support block 421 after positioning, so that the automobile pump cover can be kept level after being placed, the positioning column 411 is further preferably provided with a cylindrical section 411b at the lower end of the tapered section 411a in this embodiment, and the diameter of the cylindrical section 411b is greater than the maximum diameter of the tapered section 411a; the height of the upper end surface a of the cylindrical section 411b is flush with the upper end surface of the support block 421, so that rapid positioning is achieved while reliably ensuring the horizontality of the clamping. Of course, in order to further avoid the positioning column from scratching the positioning hole when installing the automobile pump cover, and to make the insertion into the positioning hole of the automobile pump cover smoother, the upper end of the tapered section 411a is preferably provided with a spherical surface 412 in this embodiment.

[0028] In addition, since the piston rod stroke of the cylinder is fixed after it is selected, the pressing force of the pressure head 32 on the automobile pump cover needs to be adjusted during the machine adjustment process to avoid excessive pressure and damage to the automobile pump cover, and of course to avoid too little pressure and unstable clamping, but it is difficult to adjust the determined piston rod stroke. For this reason, the end of the pressure head 32 away from the cylinder 31 is preferably provided with an adjustment rod 35 in this embodiment; the adjustment rod 35 is threadedly connected to the pressure head 32, and after compression, the head end of the adjustment rod 35 contacts the automobile pump cover; that is to say, the adjustment rod 35 can be rotated to change the screw-out length of the adjustment rod 35, thereby adjusting the pressing force.

[0029] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
