Technical Field

[0001] The utility model belongs to the technical field of piston rod processing, in particular to a cutting device for processing automobile piston rods. Background Art

[0002] The automobile piston rod is one of the key components in the engine. It is located between the piston and the connecting rod and plays the role of connecting and transmitting power. At the same time, the shock absorber, which is one of the most important components of the automobile, also requires the use of the piston rod.

[0003] When processing automobile piston rods, it is often necessary to cut their surfaces, and the cutting operation requires the use of a cutting device. When cutting the automobile piston rod, the existing cutting device generally needs to clamp and fix the automobile piston rod first, and the clamping is usually fixed by clamping the outside of the automobile piston rod with a clamp. During the clamping process, the clamp easily blocks the cutting blade, so it is often necessary to clamp the uncut part by clamping the cut part after cutting some parts, so as to carry out the cutting operation. This is inconvenient in actual use, so it is necessary to improve the clamping mechanism of the cutting device. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, the utility model provides a cutting device for processing automobile piston rods, comprising a processing table 1 and a support plate 2, which is movably mounted on the processing table 1;

[0026] A positioning mechanism 3, which is slidably mounted on the support plate 2;

[0027] A transmission mechanism 4, which is fixed to the support plate 2;

[0028] A driving mechanism 5, which is fixedly mounted on the support plate 2 and cooperates with the transmission mechanism 4 to drive the positioning mechanism 3;

[0029] The positioning mechanism 3 includes a movable block 301 which is slidably connected to the support plate 2 , a positioning block 302 is fixedly connected to the movable block 301 , a connecting block 303 is slidably mounted inside the support plate 2 , and the movable block 301 and the connecting block 303 are fixedly connected.

[0030] By adopting the above scheme, the movable block 301 and the positioning block 302 can be supported as a whole by the connecting block 303, and the movable block 301 and the connecting block 303 are restricted by the support plate 2, so they can only move horizontally inside the support plate 2, and the positioning block 302 can be placed inside the automobile piston rod, thereby fixing the automobile piston rod by tension inside the automobile piston rod.

[0031] like Figure 4 As shown, the transmission mechanism 4 includes a rotating shaft 401, a rotating wheel 402 and a push-pull rod 403. The rotating shaft 401 is fixedly connected to the support plate 2, and the rotating wheel 402 is movably assembled on the outside of the rotating shaft 401. The push-pull rod 403 is hinged on the rotating wheel 402, and the end of the push-pull rod 403 away from the rotating wheel 402 is hinged to the connecting block 303.

[0032] By adopting the above scheme, the rotating wheel 402 can be restricted by the rotating shaft 401, so that the rotating wheel 402 can only rotate. When the rotating wheel 402 rotates, the two connecting blocks 303 can be pushed to move away from each other through the push-pull rod 403, so the movable block 301 and the positioning block 302 will move at the same time, thereby fixing the automobile piston rod placed on the positioning block 302.

[0033] like Figure 3 As shown, the driving mechanism 5 includes a fixed plate 501 , a pneumatic cylinder 502 and a moving block 503 . The fixed plate 501 is fixedly mounted on the front of the support plate 2 , the pneumatic cylinder 502 is fixedly mounted on the fixed plate 501 , and the moving block 503 is fixedly connected to the pneumatic cylinder 502 .

[0034] By adopting the above scheme, the pneumatic cylinder 502 is supported by the fixed plate 501. When the pneumatic cylinder 502 is running, the moving block 503 can move left or right, and the movement of the moving block 503 can cause the rotating wheel 402 to rotate, thereby achieving the effect of fixing the automobile piston rod or loosening the automobile piston rod.

[0035] like Figure 3 As shown, the driving mechanism 5 further includes a round rod 504 , which is slidably mounted inside the moving block 503 , and the round rod 504 is also fixedly connected to the rotating wheel 402 .

[0036] By adopting the above scheme, through the design of the round rod 504, when the moving block 503 moves, the round rod 504 will be pulled to move, and the movement of the round rod 504 will cause the rotating wheel 402 to rotate around the rotating axis 401, and because the height of the round rod 504 changes as the rotating wheel 402 rotates, the round rod 504 will move inside the moving block 503, thereby causing the rotating wheel 402 to rotate.

[0037] like Figure 1 As shown, a first electric slide rail 6 is fixedly installed on the top of the processing table 1, and the outside of the first electric slide rail 6 is slidably connected to the support plate 2. There are two first electric slide rails 6, and the lengths of the two first electric slide rails 6 are the same.

[0038] By adopting the above solution, by installing the support plate 2 on the first electric slide rail 6 , the support plate 2 can be moved, so that the automobile piston rod can contact the cutting mechanism 8 and be cut by the cutting mechanism 8 .

[0039] like Figure 1 As shown, a second electric slide rail 7 is fixedly installed on the top of the processing table 1, and a cutting mechanism 8 is slidably mounted on the outside of the second electric slide rail 7.

[0040] By adopting the above solution, the cutting mechanism 8 can move left and right through the second electric slide rail 7, so that the cutting mechanism 8 can cut from one side of the automobile piston rod to the other side, which is convenient for cutting.

[0041] like Figure 2 As shown, there are four positioning blocks 302 . The four positioning blocks 302 are of the same size and are divided into two groups. The two groups of positioning blocks 302 face two directions.

[0042] By adopting the above scheme, through the design of the positioning block 302, when the positioning block 302 facing upward is fixing the automobile piston rod, the cutting mechanism 8 can cut the side of the automobile piston rod, and when the positioning block 302 facing sideways is fixing the automobile piston rod, the cutting mechanism 8 can cut the front and back of the automobile piston rod, and the thickness of the automobile piston rod is greater than the height of the positioning block 302.

[0043] The working principle and use process of this utility model:

[0044] When it is necessary to cut the side of the automobile piston rod, the automobile piston rod is placed on the positioning block 302 facing upwards. When it is necessary to cut the front and back sides of the automobile piston rod, the automobile piston rod is placed on the positioning block 302 facing the side, and the positioning block 302 is allowed to enter the interior of the automobile piston rod. Then the pneumatic cylinder 502 is started. The operation of the pneumatic cylinder 502 will drive the moving block 503 to move. When the moving block 503 moves, it will pull the round rod 504 to move, so that the rotating wheel 402 can rotate around the rotating shaft 401. The rotating wheel 402 pushes the two connecting blocks 303 to move away from each other through the push-pull rod 403, so that the automobile piston rod placed on the positioning block 302 can be fixed.

[0045] Then, the first electric slide rail 6 can make the support plate 2 move backward as a whole, so that the part of the automobile piston rod that needs to be cut is located on the side of the cutting mechanism 8, and the cutting mechanism 8 can be moved by the second electric slide rail 7 to complete the cutting of the automobile piston rod.
