[0021] By providing a fixing device for the processing of fuel injection pump bodies in the embodiments of the present application, the problem that in the prior art, when performing internal cylinder body grinding operations on fuel injection pump bodies, it is necessary to first clamp them, grind the top, loosen the clamping parts after grinding, and then flip the cylinder body so that the front end of the cylinder body faces upward, and then grind the front end of the cylinder body, which is troublesome to operate, is solved.

[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] The embodiments of the present utility model disclose a fixing device for the processing of fuel injection pump bodies.

[0024] According to the attached Figures 1-4 As shown, it includes a processing fixed table 1 and a reversible fixed fixture 2 arranged on the top of the processing fixed table 1. The reversible fixed fixture 2 includes an adaptable clamping plate 21, a horizontal sliding carrier base 25, a vertical sliding carrier plate 26 and a rotating connecting piece 211;

[0025] The horizontal sliding carrier base 25 is horizontally slidably arranged on both sides of the top of the processing fixed table 1. The vertical sliding carrier plate 26 is vertically slidably arranged inside the horizontal sliding carrier base 25. The rotating connecting piece 211 is rotatably connected to the outer wall of the vertical sliding carrier plate 26. The adaptable clamping plate 21 is fixedly arranged on the outer surface of the rotating connecting piece 211.

[0026] The processing fixture table 1 includes a processing carrier plate 11, a slide rail 12, and a material-carrying slide block 14. The slide rail 12 is fixedly arranged on the top of the processing carrier plate 11, and the material-carrying slide block 14 is slidably connected to the top of the slide rail 12. During use, the fuel injection pump body is placed on the top of the material-carrying slide block 14, and then it is pushed forward along the slide rail 12 to move it between two sets of laterally sliding carrier blocks 25, waiting for clamping and processing. By using the material-carrying slide block 14, the two sides of the bottom of the fuel injection pump body are suspended in the air, which is convenient for the fitting clamping plates 21 to clamp the two sides of the fuel injection pump body in a wrapping manner, avoiding slippage during use.

[0027] A chute 13 perpendicular to the slide rail 12 is opened at the bottom of the processing carrier plate 11. A sliding frame 22 is fixedly welded to the bottom of the laterally sliding carrier block 25. The sliding frame 22 is slidably connected in the chute 13. A bidirectional lead screw 23 is rotatably connected to the bottom of the chute 13. The two ends of the bidirectional lead screw 23 are respectively threadedly connected to the two sets of sliding frames 22. A clamping motor 24 is fixedly installed at the bottom of the processing carrier plate 11. The output end of the clamping motor 24 is fixedly connected to one end of the bidirectional lead screw 23. By starting the clamping motor 24, it drives the bidirectional lead screw 23 to rotate, so that the two sets of sliding frames 22 slide towards the middle along the chute 13, so that the two sets of fitting clamping plates 21 can quickly clamp and fix the fuel injection pump body from both sides.

[0028] A lifting motor 28 is fixedly installed on the top of the laterally sliding carrier block 25. A lifting slider 29 is fixedly connected to the back of the vertically sliding carrier plate 26. A lifting lead screw 27 is fixedly installed at the output end of the lifting motor 28. The lifting lead screw 27 is threadedly connected to the lifting slider 29. By starting the lifting motor 28, it drives the lifting lead screw 27 to rotate, so that the lifting slider 29 drives the vertically sliding carrier plate 26 to slide up and down, lifting the fuel injection pump body to facilitate its flipping.

[0029] A rotating motor 2100 is fixedly installed on the back of the lifting slider 29. The output end of the rotating motor 210 passes through the lifting slider 29 and the vertically sliding carrier plate 26, and the output end of the rotating motor 210 is fixedly connected to the rotating connector 211. By starting the rotating motor 210, it drives the fitting clamping plate 21 to flip through the rotating connector 211, thereby adjusting the direction of the fuel injection pump body.

[0030] The lifting slider 29 is vertically slidably arranged in the middle of the laterally sliding carrier block 25. Limiting grooves 212 are opened on both sides of the inner wall of the laterally sliding carrier block 25. The back of the vertically sliding carrier plate 26 is slidably connected inside the limiting grooves 212 to prevent the vertically sliding carrier plate 26 from deflecting during the up and down sliding process.

[0031] The clamping motor 24 drives two groups of horizontally sliding carriers 25 to move towards the middle, so that two groups of adapted clamping plates 21 clamp and fix the fuel injection pump body, and then grind its top. After the top grinding is completed, the lifting motor 28 drives the lifting slider 29 to rise, and then the rotating motor 2100 drives the adapted clamping plate 21 to rotate 90 degrees, so that the front end of the fuel injection pump body faces upward. Then the lifting motor 28 drives the adapted clamping plate 21 to descend so that it contacts the top of the processing carrier plate 11. At this time, it is convenient to grind the front end after flipping it without loosening the fixture, which is easy to operate and improves the processing efficiency.
