Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, in particular to a milling machine used for processing automobile air-conditioning compressor pistons. Background Art

[0002] The automobile air-conditioning compressor is the heart of the automobile air-conditioning refrigeration system, and plays the role of compressing and transporting refrigerant vapor. The compressor is divided into two types: fixed displacement and variable displacement. The piston in the existing automobile air-conditioning compressor is generally processed by corresponding milling machine equipment, and the milling machine is provided with a corresponding fixing fixture, so that the piston blank can be clamped and fixed. However, when the existing clamping block clamps the rectangular piston blank, two parallel clamping blocks are used for clamping. When the piston blank is processed into a cylindrical shape, the clamping method at this time will cause unstable processing and reduce the product processing quality, so it needs to be improved.

The inner side of the tooth block 703 is meshed with the surface of the second gear 702. A driven gear 704 is fixedly sleeved on the bottom of the movable column 6. The driven gear 704 and the movable column 6 are driven to rotate as a whole, so that the first gear 701 can rotate synchronously with the second gear 702, so that the tooth block 703 and the clamping block 5 on the other side are deflected in the opposite direction.

[0034] like Figures 2 to 4 As shown, a slider 9 is movably installed in the inner cavity of the clamping platform 4, and the top of the slider 9 is movably connected to the bottom of the clamping block 5. The movable column 6 is movably connected to the slider 9 and the inner cavity of the clamping platform 4 respectively, and the clamping block 5 is connected to the surface of the movable column 6 and is fixedly connected and movably connected to the clamping blocks 5 on both sides respectively.

[0035] The number of the clamping blocks 5 is four, and the four clamping blocks 5 form a pair of two.

[0036] By adopting the above solution, by providing the slider 9, when the pair of clamping blocks 5 and the movable column 6 at the front end move as a whole, they will move smoothly under the limit of the slider 9 and the inner wall of the clamping platform 4.

[0037] like Figure 2 and Figure 4 As shown, the inner wall of the clamping platform 4 is threadedly sleeved with the adjusting screw 10 , and the rear end of the adjusting screw 10 is movably sleeved with the front face of the sliding block 9 .

[0038] By adopting the above solution, an adjusting screw 10 is provided. When the operator rotates the adjusting screw 10, the slider 9 and the front clamping block 5 can be driven to move forward and backward as a whole, so as to clamp piston blanks of various sizes.

[0044] The working principle and use process of this utility model:

[0045] First, the operator can place the piston blank on the top of the clamping platform 4, and then rotate the adjusting screw 10 to drive the front end slider 9 and the clamping block 5 as a whole backward to clamp the piston blank. At this time, the processing component 2 can be started to process the piston blank on the top of the clamping platform 4.

[0046] Subsequently, when the piston blank is processed into a cylindrical shape, the screw motor group 803 can be started to drive the driving tooth plate 801 and the telescopic connecting rod 802 to move to the right as a whole, which can drive the two driven gears 704 and the movable column 6 as well as the clamping block 5 on the other side to deflect. At the same time, the first gear 701 can be rotated, and then the second gear 702 can be driven to rotate the driving tooth block 703 and the clamping block 5 on the other side to deflect in the opposite direction, and finally the two clamping blocks 5 can be deflected inward to stably clamp the cylindrical piston.
