Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to an oilstone clamping mechanism. Background Art

[0002] In the high-precision production process, oilstones are required for grinding processing. The oilstones usually need to be fixed and installed using a clamping device. Usually, the oilstone is installed by placing the oilstone inside a box body and squeezing the oilstone with bolts, or by opening a round hole at one end of the oilstone and inserting the bolt into the round hole, thereby limiting the movement of the oilstone and completing the installation of the oilstone and the box body. After using the oilstone for a long time, the length of the oilstone becomes shorter, so the oilstone needs to be replaced. The oilstone becomes shorter due to grinding, so the end of the oilstone is almost parallel to the box body. As a result, when the oilstone is taken out, the area of ​​force exerted by the hand on the oilstone becomes smaller, and it is impossible to apply force well, making it difficult to take the oilstone out of the box body.

[0022] Furthermore, the vertical cross-sectional dimension of the placement groove corresponds to the vertical cross-sectional dimension of the oilstone 2, the inner wall of the threaded hole 5 is provided with a thread, the inner wall thread of the threaded hole 5 is meshed with the outer wall thread of the fixing bolt 3, the circular groove 4 is a smooth inner wall, and the diameter of the circular groove 4 corresponds to the outer diameter of the fixing bolt 3, by inserting one end of the oilstone 2 with the circular groove 4 into the placement groove, the fixing bolt 3 is threadedly connected with the threaded hole 5, and the rod of the fixing bolt 3 is inserted into the inner wall of the circular groove 4, thereby limiting the movement of the oilstone 2 inside the placement groove, and realizing the fixed installation of the oilstone 2 and the box body 1.

[0023] Specifically, a moving groove is provided at the top of the box body 1, and guide grooves 8 are symmetrically provided on both sides of the inner wall of the moving groove. A guide frame 62 is sleeved on the outer wall of the moving block 61, and the guide frame 62 is connected with the guide groove 8 through insertion. A cavity is provided inside the moving block 61, and an insertion hole is provided at the bottom end of the inner wall of the cavity. The insertion block 63 is connected with the insertion hole through insertion. A baffle 64 is fixedly connected to the top of the insertion block 63, and a pushing spring 65 is provided at the top of the baffle 64.

[0024] Furthermore, the thickness of the guide frame 62 corresponds to the thickness of the movable groove. The guide frame 62 is fixedly mounted on the outer wall at the bottom of the movable block 61. The guide frame 62 is connected to the movable block 61 by welding. The horizontal cross-sectional dimensions of the insertion hole and the guide groove 8 correspond to each other, both of which are 1.01 times the horizontal cross-sectional dimensions of the insertion block 63. The size of the baffle 64 is 1.2 times the size of the insertion hole. The top and bottom ends of the pushing spring 65 are fixedly connected to the top of the inner wall of the cavity and the top of the baffle 64 by bonding, respectively. The pushing spring 65 is always in a compressed state in the cavity. The inner diameter of the pushing spring 65 is 1.5 times the size of the circular hole.

Under the action of the restoring force of the pushing spring 65, the pushing spring 65 pushes the baffle 64, so that the baffle 64 drives the plug-in block 63 to be inserted into the inside of the plug-in groove 7, and then the moving block 61 is pulled close to the inserting groove 7. Move in the direction of the threaded hole 5 so that the threaded hole 5 and the circular groove 4 are in the same straight line, insert the fixing bolt 3 into the circular groove 4 and the threaded hole 5, and install the box body 1 and the oil stone 2. When the oil stone 2 needs to be replaced, remove the fixing bolt 3 and move the moving block 61 away from the threaded hole 5 until the moving block 61 cannot move. At this time, most of the volume of the oil stone 2 is exposed from the placement groove, and then pull the pull ring 67 to move away from the guide frame 62. The pull ring 67 drives the round rod 66, the round rod 66 drives the baffle 64, and the baffle 64 drives the plug-in block 63 to leave the plug-in groove 7, so that the oil stone 2 can be taken out of the placement groove.
