[0035] In order to be able to quickly fix the engine cylinders 29 in batches, after the engine cylinders 29 are initially fixed by the positioning columns 2, the engine cylinders 29 are arranged in a matrix, and each plug-in plate 401 is inserted into the gap between two adjacent engine cylinders 29 through the sliding mechanism 3, and at the same time, the plug-in plate 401 can be located between the upper and lower heat dissipation fins on the side of the engine cylinder 29.

Since the lower end of the top rod 408 is a frustum, the downward movement of the top rod 408 will move away from each other through the two movable rods 406, so that the movable rod 406 drives the clamping plate 404 to move, so that the clamping plate 404 will eventually collide with the side wall of the engine cylinder 29. The clamping plates 404 on each plug plate 401 act at the same time, and finally all the engine cylinders 29 on the processing table 1 are fixed, and then the first electric push rod 8 continues to drive the grinding mechanism 6 to move downward for grinding.

The lower end of the squeeze plate 7 is slidably connected in the first movable hole. When the first electric push rod 8 drives the top plate 5 to move downward, the top plate 5 will drive the squeeze plate 7 to move downward, so that the squeeze plate 7 and the slide 4071 collide and break the slide 4071 to move a certain distance toward the center of the processing table 1, so that the slide 4071 is plugged with the end of the plug plate 401, and the plug plate 401 is supported by the slide 4071.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Fig.10The lower ends of several positioning columns 2 are fixedly connected to a connecting plate 11.

When the grinding rod 602 on the grinding mechanism 6 moves downward, the front guide rod 603 at the lower end of the grinding rod 602 is plugged into the guide sleeve 25 at the upper end of the positioning column 2, and while guiding the grinding rod 602, as the grinding rod 602 moves downward, it will force the positioning column 2 to move downward, and finally make the guide sleeve 25 at the upper end of the positioning column 2 move down below the upper surface of the processing table 1. At this time, the limit frame 17 at the lower end of the third guide rod 12 is inserted into the socket 15 on the upper part of the cross beam 14 and is slidably connected with the limit block 16 to limit the third guide rod 12. After grinding is completed, the first electric push rod 8 moves up, so that the top plate 5 can drive the grinding rod 602 to move up and reset. At this time, the slide 4071 is reset, and the support for the plug plate 401 is released. Then the second electric push rod 10 under the base frame 9 moves down, so that the processing table 1 moves down. At this time, the engine cylinder block 29 is limited by the plug plate 401. The engine cylinder block 29 is separated from the upper surface of the processing table 1, and then the two sliding mechanisms 3 cooperate to transfer all the engine cylinder blocks 29 to the unloading table 27.

[0039] See also Figure 1 and Figure 4A cleaning brush 21 is movably provided on the upper part of the processing table 1, and a vertical plate 22 is movably provided on the front surface of the processing table 1. The upper end of the vertical plate 22 is fixedly connected to the cleaning brush 21, and a slide plate 23 is fixedly provided on the lower end of the vertical plate 22.

A discharge port 26 for discharging debris is provided on the left edge of the upper part of the processing table 1.

[0040] In order to facilitate the cleaning of the debris on the surface of the processing table 1, when the sliding mechanism 3 drives the clamping mechanism 4 to move toward the processing table 1, it will simultaneously drive the spring pin 24 to move toward the vertical plate 22, so that the rear end of the spring pin 24 can be inserted into the second movable hole. When the grinding is completed, the sliding mechanism 3 drives all the polished engine cylinders 29 to move toward the unloading table 27, so that the spring pin 24 can push the vertical plate 22 and the slide plate 23 to move to the left. During the movement, the vertical plate 22 can push the cleaning brush 21 to move on the surface of the processing table 1, and push the debris on the surface of the processing table 1 toward the discharge port 26. The slide plate 23 moves to the left and contacts with the baffle 18, causing the baffle 18 to rotate, and the baffle 18 will not affect the slide plate 23. The brush plate 23 then moves to the left and eventually pushes the debris into the discharge port 26 for discharge. When the brush plate 23 returns to move to the right, the spring pin 24 is inserted into the second movable hole again. During the rightward movement, the vertical plate 22 drives the brush plate to reset. At the same time, the slide plate 23 moves to the right and will collide with the baffle 18 again. The baffle 18 is subjected to resistance and moves to the right together with the slide plate 23. During the movement, the limit block 16 is pulled out of the limit frame 17, so that the positioning column 2 is reset. After the limit block 16 moves to a certain distance, as the resistance gradually increases, the rotation angle of the baffle 18 gradually increases, and finally the slide plate 23 passes over the baffle 18 and continues to move to the right and reset. At the same time, the baffle 18 is reset with the cooperation of the fourth spring 19 and the fifth spring 20.

[0041] During the specific work, the staff inserts the engine cylinder 29 into the positioning column 2, and the positioning column 2 passes through the shaft hole on the engine cylinder 29 to pre-position the engine cylinder 29, and then puts all the engine cylinders 29 in a matrix in turn, and then drives the respective clamping mechanisms 4 to move through the sliding mechanisms 3 on the front and left sides of the processing table 1, and inserts the two clamping mechanisms 4 staggered up and down between the engine cylinders 29 placed in the matrix for cross-fixation, and the plug plate 401 in the clamping mechanism 4 will be inserted into each of the two adjacent The plug plate 401 is located between the upper and lower heat dissipation fins on the side wall of the engine cylinder 29. When the first electric push rod 8 drives the top plate 5 to move downward, the extrusion plate 7 first drives the slide 4071 to move toward the plug plate 401, so that the slide 4071 is plugged with the corresponding plug plate 401 to support the plug plate 401. Then the push rod 408 gradually moves downward and is inserted between the two movable rods 406 on the surface of the lower plug plate 401, forcing the two movable rods 406 to move away from each other, thereby driving the movable rods 406 to move toward the plug plate 401. The connected clamping plate 404 is movably abutted against the outer wall of the engine cylinder 29, and the four sides of the same engine cylinder 29 are abutted by the clamping plate 404, so that the engine cylinder 29 is fixed, and at the same time, the grinding rod 602 moves down, and the front guide rod 603 at the lower end of the grinding rod 602 is finally inserted into the guide sleeve 25 at the upper end of the positioning column 2, so that the two are connected, and then the grinding rod 602 continues to move down, so that the positioning column 2 gradually moves down, and finally the grinding rod 602 is inserted into the shaft hole at the upper end of the engine cylinder 29 for grinding, and more After the residual burrs are removed and the grinding is completed, the top plate 5 is reset, so that the top rod 408 and the extrusion plate 7 are reset. At this time, the upper end surface of the guide sleeve 25 at the upper end of the positioning column 2 is flush with the upper surface of the processing table 1, and the two sliding mechanisms 3 cooperate with each other to feed all the processed engine cylinder bodies 29 to the unloading table 27. At the same time, during the feeding process, the brush plate and the slide plate 23 will be driven to move synchronously. The back and forth movement of the brush plate can remove the debris on the surface of the processing table 1, and the back and forth movement of the slide plate 23 can release the limit of the positioning column 2, so that the positioning column 2 can be reset.
