Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a milling machine used for processing a piston of an air-conditioning compressor. Background Art

[0002] There are many structural forms of air-conditioning compressors, including reciprocating piston type, rolling rotor type, scroll type and large screw type. Among them, although the reciprocating piston compressor is less used, it can still be seen in certain specific occasions. The piston of the air-conditioning compressor is one of its core components, which is mainly responsible for compressing the refrigerant during the compression process.

[0003] Before being used, the air-conditioning compressor piston needs to go through multiple processes to make it qualified. When producing the air-conditioning compressor piston, the first step is to make a model, and then pour liquid into it to allow the model to take shape; finally, a milling machine is needed to perform fine grinding and hole drilling operations on the already formed air-conditioning compressor piston to meet subsequent use.

[0049] By adopting the above technical scheme, the milling machines on the market need to hold the workpiece to be processed during operation so that the workpiece can remain in a fixed state. However, during processing, since the model is a rough model, a series of operations such as grinding and drilling need to be performed by the milling machine. However, after the holding operation, the milling machines on the market can only allow the workpiece to move horizontally up and down, left and right, and front and back, and cannot adjust the angle of the workpiece. As a result, when the equipment processes the side of the workpiece and other places that need to be processed, the workpiece needs to be removed and reinstalled so that the equipment can process the workpiece, and the process is relatively time-consuming. The structure of the device is as follows: it includes a body 1, a vertical lifter 101 is fixedly installed on the upper left end of the body 1, and a lifting platform 14 is fixedly installed on the top of the lifter 101, and the right side of the lifting platform 14 is The left and right sliding platforms 15 are installed on the machine body 1 for sliding movement at the end.

During use, the left and right sliding platforms 15 can move forward and backward under the action of the screw adjustment rod, and the left and right sliding platforms 15 can slide left and right under the action of their own adjustment rods. A convex slide groove 151 of the same structure is provided at the front and rear edge positions of the upper end faces of the left and right sliding platforms 15. A convex slide 161 is installed for sliding movement inside the convex slide groove 151, and a U-shaped rod is fixedly installed between the left ends of the convex slides 161 for connecting the two convex slides 161, so that the user can pull out the convex slide 161 inside the convex slide groove 151 at the same time, and a processing platform 16 is fixedly installed between the tops of the two convex slides 161.

[0050] Two servo motors 17 are fixedly installed on the upper end surface of the processing platform 16, and the two servo motors 17 are on the same horizontal line, and two arc seats are symmetrically installed between the two servo motors 17, wherein a worm 18 is fixedly installed on the output shaft of the left servo motor 17, and a rectangular frame 19 is fixedly installed on the output shaft of the right servo motor 17, and a gear 191 is installed horizontally and rotatably at the inner center of the rectangular frame 19, and the gear 191 is meshed with the worm 18. During use, the worm 18 can drive the gear 191 to rotate, and the front and rear ends of the rotating shaft of the gear 191 extend to the outside of the rectangular frame 19, and a U-shaped frame 20 is fixedly installed on the circumferential surface of the rotating shaft. During use, the gear When 191 rotates, it can work synchronously with the U-shaped frame 20; the opening of the U-shaped frame 20 faces downward, and a storage table 21 is fixedly installed on the top of the U-shaped frame 20, and a slide groove 22 is opened on the upper end surface of the storage table 21, and a screw rod 23 is rotatably installed inside the slide groove 22, and the right end of the screw rod 23 extends to the outside of the slide groove 22, which is used to facilitate the user to manually rotate the screw rod 23; in addition, a V-shaped clamp 24 is rotatably installed on the circumferential surface of the screw rod 23, and the V-shaped clamp 24 is located on the upper end surface of the storage table 21, and secondly, the same V-shaped clamp 24 is fixedly installed on the circumferential surface of the storage table 21. During use, the screw rod 23 rotates, so that the two V-shaped clamps 24 can be moved closer or farther away.

[0051] When in use, the processing personnel places the piston on the upper end of the horizontal storage table 21, rotates the screw 23, and drives the V-shaped clamp 24 to gradually approach under the drive of the screw 23, so as to clamp the workpiece. After completion, the processing personnel adjusts the distance between the workpiece and the milling machine tool; during processing, the lifter 101 operates to make the lifter 101 move up or down. During the movement of the lifter 101, it can push the left and right sliding tables 15 and other structures to move synchronously. When operating, the processing personnel can make the left and right sliding tables 15 slide horizontally back and forth and left and right under the adjusting rod, so that the processing platform 16 can meet the processing conditions; after adjusting the position of the processing platform 16, the workpiece is processed, and then during the processing, when it is necessary to process the side surface of the workpiece, the servo motor 17 is started, and the output shaft of the servo motor 17 drives the worm 18 to rotate. Under the influence of the worm 18 The gear 191 can be driven to rotate, and under the action of the gear 191, the U-shaped frame 20 can be rotated synchronously, so that the U-shaped frame 20 rotates with the storage table 21, and then the storage table 21 can rotate with the workpiece, and the workpiece originally in a vertical state can be rotated to an inclined state, so as to facilitate the side processing of the workpiece. Secondly, under the operation of the worm 18, the workpiece can only be rotated left and right, and when the output shaft of the servo motor 17 directly rotates with the rectangular frame 19, the storage table 21 can be rotated forward and backward, so that the workpiece can be tilted forward and backward; with the cooperation of the above-mentioned multiple structures, the workpiece can be rotated left and right, forward and backward, so that when the side surface of the workpiece is processed, the processing personnel do not need to dismantle and reinstall the workpiece, which saves processing time, and during the processing, it can prevent the dust on the hands of the processing personnel from contaminating the piston, ensuring the fineness of the processed parts and avoiding quality problems.
