Description

Technical Field

[0001] This utility model relates to the field of crankshaft grinding machine technology, and specifically to crankshaft grinding machine fixtures. Background Technology

[0002] The crankshaft grinding machine fixture mechanism consists of a fixture body, a crankshaft clamping and positioning block, a clamping cylinder mounted on the fixture body, and a clamping cylinder that pushes a clamping rod to clamp the crankshaft and cause it to rotate. When the crankshaft is being processed by the grinding machine, it needs to be clamped to prevent slippage.

[0003] Existing crankshaft grinding machine fixtures mostly use a chuck-like mechanism to lock the eccentric part of the crankshaft, thus controlling the grinding machine's position and rotating the product for machining. However, this fixture mechanism is cumbersome to set up during use, requires a certain locking time, cannot be set up quickly, is time-consuming, and has low efficiency. Therefore, we propose a crankshaft grinding machine fixture. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a crankshaft grinding machine fixture.

[0005] The technical solution adopted by this utility model to solve its technical problem is a crankshaft grinding machine fixture, including a first paddle bracket and a second paddle bracket. Two first bolts are installed on both sides of the first paddle bracket. A spring is sleeved on the outer periphery of the first bolt. A second bolt is installed in the middle of the first paddle bracket and the second paddle bracket. Third bolts are installed on both sides of the second bolt in the middle of the first paddle bracket and the second paddle bracket. A paddle block is slidably connected in the central groove of the first paddle bracket and the second paddle bracket.

[0006] By adopting the above technical solution, the mounting end of the crankshaft component is aligned with the arc-shaped grooves of the two shift blocks and inserted, thereby pushing the shift block connected to the first shift bracket to move. The first shift bracket compresses the springs on the outer periphery of the first bolts on both sides, thereby expanding the distance between the two shift blocks, thus inserting the crankshaft component between the two shift blocks. Subsequently, the spring's return pushes the first shift bracket and its connected shift block toward the second shift bracket, thereby cooperating with the second shift bracket to achieve quick clamping and automatic centering.

[0007] During clamping, the gap between the paddle and the bracket groove connected to it can be adjusted by rotating the third bolt. This increases or decreases the movement distance between the first paddle bracket and the paddle relative to the initial position of the paddle during clamping, thereby adjusting the spring force. At the same time, the spring force can be directly adjusted by tightening or loosening the first bolt, thus adapting to the processing of crankshafts of different sizes.

[0008] Specifically, positioning pins are engaged in the bracket grooves on both sides of the first paddle bracket, and the first paddle bracket is assembled to one side of the tray through the positioning pins engaged on both sides.

[0009] By adopting the above technical solution, the positioning pins are inserted into the grooves on both sides of the two paddle brackets to install the paddle brackets onto the side wall of the tray during the assembly of the paddle brackets.

[0010] Specifically, a support column is provided on the side of the tray away from the first lever bracket, and the end of the support column away from the tray is detachably installed on the side wall of the connecting base.

[0011] By adopting the above technical solution, the support plate is installed on the connecting base through the support column, thereby the entire paddle bracket is installed on the CNC grinding machine through the connecting base.

[0012] Specifically, the first paddle bracket and the second paddle bracket are mirror images of each other, and the surfaces of the first paddle bracket and the second paddle bracket are provided with through holes that match the first bolt, the second bolt and the third bolt.

[0013] By adopting the above technical solution, the two paddles are directly mirrored and spliced ​​together, and then the first bolt, the second bolt and the third bolt are screwed into each through hole to complete the overall assembly of the paddle bracket.

[0014] Specifically, the bottom two sides of the second paddle bracket are fitted with first nuts that match the first bolt.

[0015] By adopting the above technical solution, the two lever brackets are connected by screwing the first nut and the first bolt together.

[0016] Specifically, the crankshaft component is held in the center of the two pry bars.

[0017] By adopting the above technical solution, the paddle block connected to the first paddle bracket moves toward the displacement direction of the second paddle bracket under the action of the spring, thereby clamping the crankshaft component.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The technical solution of this application aligns the mounting end of the crankshaft component with the arc-shaped grooves between the two shift blocks and inserts it, thereby pushing the shift block connected to the first shift bracket to move. The first shift bracket compresses the springs on the outer periphery of the first bolts on both sides to expand the distance between the two shift blocks, thereby inserting the crankshaft component between the two shift blocks. Then, the spring returns to its original position to push the first shift bracket and the shift block connected to it toward the second shift bracket, thereby cooperating with the second shift bracket to achieve quick clamping and automatic centering.

[0020] During clamping, the gap between the paddle and the bracket groove connected to it can be adjusted by rotating the third bolt. This increases or decreases the movement distance between the first paddle bracket and the paddle relative to the initial position of the paddle during clamping, thereby adjusting the spring force. At the same time, the spring force can be directly adjusted by tightening or loosening the first bolt, thus adapting to the processing of crankshafts of different sizes. Attached Figure Description

A paddle block 7 is slidably connected in the central groove of the first paddle bracket 1 and the second paddle bracket 13.

[0028] In use, the crankshaft component 10 is inserted between the arc-shaped grooves of the two paddle blocks 7, thereby pushing the paddle block 7 connected to the first paddle bracket 1 to move. The first paddle bracket 1 compresses the spring 3 on the outer periphery of the first bolt 2 on both sides, thereby expanding the distance between the two paddle blocks 7, thus inserting the crankshaft component 10 between the two paddle blocks 7. Then, the spring 3 returns to its original position, pushing the first paddle bracket 1 and the paddle block 7 connected to it toward the second paddle bracket 13, thereby cooperating with the second paddle bracket 13 to achieve quick clamping and automatic centering.

[0029] During clamping, the gap between the lever block 7 and the groove of the bracket connected to it can be adjusted by rotating the third bolt 6. This increases or decreases the movement distance between the first lever bracket 1 and the lever block 7 relative to the initial position of the lever block 7 during clamping, thereby adjusting the force of the spring 3. At the same time, the spring force can be directly adjusted by tightening or loosening the first bolt 2, thus adapting to the processing of crankshafts of different sizes.

[0030] As shown in the figure, positioning pins 8 are engaged in the bracket grooves on both sides of the first paddle bracket 1, and the first paddle bracket 1 is assembled to one side of the tray 9 through the positioning pins 8 engaged on both sides.

[0031] When using the paddle brackets, the positioning pins 8 are inserted into the grooves on both sides of the two paddle brackets to install the paddle brackets as a whole onto the side wall of the support plate 9.

[0032] As shown in the figure, a support column 11 is provided on the side of the tray 9 away from the first lever bracket 1. The end of the support column 11 away from the tray 9 can be detachably installed on the side wall of the connecting base 12.

[0033] In use, the support plate 9 is mounted on the connecting base 12 via the support column 11, thereby mounting the entire paddle bracket onto the CNC grinding machine via the connecting base 12.

[0034] As shown in the figure, the first paddle bracket 1 and the second paddle bracket 13 are mirror images of each other, and the surfaces of the first paddle bracket 1 and the second paddle bracket 13 are provided with through holes that fit the first bolt 2, the second bolt 5 and the third bolt 6.

[0035] When in use, the two paddles are directly mirrored and spliced ​​together, and then the first bolt 2, the second bolt 5 and the third bolt 6 are screwed into each through hole to complete the assembly of the paddle bracket.

[0036] As shown in the figure, the bottom two sides of the second paddle bracket 13 are fitted with the first nut 4, which matches the first bolt 2.

[0037] In use, the first nut 4 and the first bolt 2 are screwed together to connect the two lever brackets.

[0038] As shown in the figure, the crankshaft component 10 is held in the center of the two levers 7.

[0039] In use, the paddle block 7 connected to the first paddle bracket 1 moves toward the displacement direction of the second paddle bracket 13 under the action of the spring 3, thereby clamping the crankshaft component 10.

[0040] The working principle and usage process of this utility model are as follows: Two paddles are directly mirror-assembled, and then the first bolt 2, the second bolt 5, and the third bolt 6 are screwed into each through hole to complete the assembly of the paddle bracket. The first nut 4 is screwed into the first bolt 2 to connect the two paddle brackets. During assembly, the positioning pin 8 is inserted into the grooves on both sides of the two paddle brackets to mount the paddle bracket as a whole onto the side wall of the support plate 9. The support pin 11 is used to mount the support plate 9 onto the connecting base 12, thus mounting the paddle bracket as a whole onto a CNC grinding machine via the connecting base 12. In use, the mounting end of the crankshaft component 10 is aligned with the arc-shaped grooves between the two paddle blocks 7 and inserted, thereby pushing the paddle block 7 connected to the first paddle bracket 1 to move. 1. The springs 3 on the outer periphery of the first bolts 2 on both sides are compressed, thereby widening the gap between the two paddle blocks 7, so that the crankshaft component 10 is inserted between the two paddle blocks 7. Then, the spring 3 returns to its original position, pushing the first paddle bracket 1 and the paddle block 7 connected to it toward the second paddle bracket 13, thereby cooperating with the second paddle bracket 13 to achieve automatic centering. During clamping, the gap between the paddle block 7 and the groove of the bracket connected to it can be adjusted by rotating the third bolt 6, thereby increasing or decreasing the movement distance between the first paddle bracket 1 and the paddle block 7 relative to the initial position of the paddle block 7 during the clamping process, thereby adjusting the force of the spring 3. At the same time, the elastic force can be directly adjusted by tightening or loosening the first bolt 2, so as to adapt to the processing of crankshafts of different sizes.
