Description

Technical Field

[0001] The utility model relates to a diamond roller for grinding plungers, belonging to the technical field of diamond rollers. Background Art

[0002] Diamond roller is a high-efficiency, high-life, low-cost grinding wheel dressing tool used in special machine tools and gear grinders for mass-produced forming grinding. The working principle of the diamond roller is: by installing it on the dressing device of the grinder, the diamond roller dresses the ordinary ceramic grinding wheel, and then grinds the parts after the grinding wheel is formed, so that the outer contour, precision and size of the diamond roller are copied to the surface of the processed parts through the grinding wheel. Its characteristics are simple machine operation, low technical requirements for operators, good precision consistency of processed products, stable quality, which can significantly improve production efficiency and product quality, reduce manufacturing costs, and easily realize grinding automation.

[0003] A Chinese patent publication (publication number: CN 217914832 U) discloses a grinding plunger diamond roller, which relates to the technical field of diamond rollers. The grinding plunger diamond roller comprises a base plate, a mounting plate is arranged on the front side of the base plate, a rotating groove is provided on the side of the mounting plate close to the base plate, the surface of the rotating groove is movably connected to the surface of the base plate, a diamond grinding layer is fixedly connected to the outer surface of the mounting plate, and two symmetrical positioning frames are fixedly connected to the front side of the base plate. The grinding plunger diamond roller slides into the interior of the assembly groove through a blocking rod and blocks the positioning frame, thereby realizing the position fixing of the mounting plate and the base plate, and making the installation and disassembly of the diamond grinding layer more convenient. At the same time, after the grinding of the diamond grinding layer is completed, the staff can more conveniently replace and maintain it, making the later maintenance of the diamond grinding layer more convenient, and at the same time, the base plate can be reused, reducing the waste of the base plate to a certain extent;

[0004] The above device mainly relies on the tension of the spring to make the various components connect to each other through the mortise and tenon structure, so as to fix the diamond roller, thereby facilitating the disassembly and replacement of the diamond roller. However, the diamond roller needs to rotate during grinding. As the diamond roller rotates, the components inside it that are squeezed and connected to each other by the spring may be offset due to the centrifugal force when the diamond roller rotates, so that these components will contact and connect to each other under the interference of the centrifugal force. At this time, the diamond roller may lose its connection with the base plate, and fly out of the top of the workbench and fall to the ground due to its own centrifugal force during rotation, thereby causing the diamond roller to be damaged due to impact.

[0005] Therefore, a diamond roller for grinding plunger is proposed. Utility Model Content

[0006] In view of this, the utility model provides a diamond roller for grinding plungers to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is implemented as follows: a grinding plunger diamond roller comprises a bottom plate, a diamond roller body is arranged on the top of the bottom plate, and insertion holes are opened around the bottom of the diamond roller body;

[0008] A fixing mechanism is provided on the inner side of the bottom plate, and the fixing mechanism includes a bidirectional screw and a box body, the box body is movably connected to the inner side of the bottom plate through a bearing, the bidirectional screw is fixedly installed in the inner cavity of the box body, the threads at the upper and lower ends of the box body surface are in opposite directions, the upper and lower sides of the bidirectional screw surface are threadedly connected with screw disks, the four sides of the two screw disks are movably connected with connecting rods, the outer sides of the eight connecting rods are movably connected with U-shaped clamps, the outer sides of the eight U-shaped clamps are fixedly installed with mounting plates, the outer sides of the four mounting plates are fixedly installed with plug rods, the top of the box body is fixedly installed with a placement frame, the bottom of the diamond roller body is clamped in the inner cavity of the placement frame, and the bottom of the bidirectional screw is fixedly installed with a turntable.

[0009] Further preferably, slots are provided around the surface of the placement frame, and the four insertion rods pass through the inner cavities of the four slots and are inserted into the inner cavities of the four insertion holes.

[0010] Further preferably, movable grooves are provided on all four sides of the surface of the box body, and the four insertion rods penetrate the inner cavities of the four movable grooves and extend to the outside of the box body.

[0011] Further preferably, the bottom of the inner cavity of the bidirectional screw is fixedly installed with a limit rod, and the four limit rods are slidably connected to the inner surfaces of the two screw plates.

[0012] Further preferably, a plurality of screw grooves are provided around the bottom of the box body, bolts are threadedly connected around the bottom of the turntable, and the tops of the four bolts are threadedly connected in the inner cavities of the screw grooves.

[0013] Further preferably, a rotating mechanism is provided at the bottom of the base plate, and the rotating mechanism includes a servo motor, which is fixedly installed at the bottom of the base plate, and the output end of the servo motor is fixedly connected to a gear, and a gear ring is fixedly installed on the surface of the box, and the rear side of the gear ring is meshed with the front side of the gear.

[0014] Further preferably, a moving groove is opened on the top of the bottom plate, and moving blocks are fixedly installed around the bottom of the gear ring, and the four moving blocks are slidably connected to the inner cavity of the moving groove.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The utility model sets a fixing mechanism, and by rotating the turntable, the bidirectional screw is rotated, and the screw disk moves inward, and the connecting rod flips outward. As the connecting rod flips, the mounting plate pushes the plug rod outward to move, so that the plug rod is removed from the inner cavity of the socket, and the socket is disassembled. When the diamond roller body cannot be used due to wear of the diamond grinding layer on its surface due to long-term use, the diamond roller body can be quickly replaced. At the same time, the device will not cause the position of the components to change due to the centrifugal force when the diamond roller body rotates, so that the diamond roller body is easy to fall off. While facilitating disassembly, it also improves its stability during installation.

[0017] Second, the utility model can limit the movement of the insertion rod by setting a slot, so as to avoid the displacement of the insertion rod when it moves, and the inability to be inserted into the inner cavity of the jack, which in turn affects the installation or disassembly of the diamond roller body. By setting a movable groove, the insertion rod can be limited to avoid the change of direction when it moves, which makes it impossible to be inserted into the inner cavity of the jack, and then affects the installation or disassembly of the diamond roller body. By setting a limiting rod, the movement of the screw disk can be limited to avoid the screw disk rotating synchronously with the bidirectional screw, which in turn affects the installation or disassembly of the diamond roller body. The bolt and the screw groove can lock the turntable to prevent the turntable from rotating synchronously due to the centrifugal force during the rotation of the fixing mechanism as a whole and the diamond roller body, thereby affecting the fixing effect of the diamond roller body. By setting the rotating mechanism, the box and the diamond roller body can be driven to rotate synchronously, and then the diamond roller body can grind the required parts through rotation. By setting the moving groove and the moving block, the rotation direction of the gear ring can be limited to prevent the gear ring from offset during rotation, and then the position of the box and the jack can be changed synchronously, thereby affecting the grinding of the parts.
