Description

Technical Field

[0001] This utility model relates to the field of spacer processing technology, specifically a precision grinding machine for the inner and outer circular planes of a slitting machine spacer. Background Technology

[0002] A slitting machine is a metal cutting device. Spacers are parts on a slitting machine used to isolate and support the equipment components. Their main function is to prevent direct contact and friction between adjacent parts. Common materials include aluminum alloy, stainless steel, and rubber.

[0003] Due to the manufacturing process, the produced metal spacers may have defects on their inner and outer walls, so they need to be ground and polished. Existing grinding machines can only grind one set of spacers at a time, which is inefficient and difficult to apply to the current high-demand production processes.

[0004] Therefore, in order to solve the above problems, a precision grinding machine for the inner and outer cylindrical surfaces of the slitting machine sleeve is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a precision grinding machine for the inner and outer cylindrical surfaces of the spacer sleeve of a slitting machine, so as to solve the problem mentioned in the background art that the existing grinding machines can only grind one set of spacers at the same time, which is inefficient and difficult to apply to the current high-demand production processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision grinding machine for inner and outer circular planes of a slitting and splitting machine, comprising: a fixed frame, wherein a rotating roller is installed on the inner side of the fixed frame; The right end of the fixing frame has a slot, and the left end of the fixing frame has a threaded groove. The fixing frame is equipped with a positioning structure, which includes a threaded sleeve. The threaded sleeve is movably installed inside the threaded groove via a thread. A rotating handle is fixedly connected to the left end of the threaded sleeve. A front abutment pad is movably installed at the right end of the threaded sleeve via a front bearing. A rear abutment pad is movably installed at the right end of the fixing frame via a rear bearing. A grinding structure is installed on the right side of the fixed frame. The grinding structure includes a fixed plate, which is fixedly installed on the right side wall of the fixed frame. A guide rod is fixedly installed on the fixed plate. Two sets of lifting motors are fixedly installed on the surface of the fixed plate. A threaded rod is fixedly connected to the output end of the lifting motor. Two sets of lifting frames are slidably installed on the guide rod. A grinding motor is fixedly installed on the lifting frame. A grinding roller is fixedly connected to the output end of the grinding motor.

[0007] Preferably, the threaded sleeve is adapted to the threaded groove, and the front abutment pad and the rear abutment pad are coaxially arranged.

[0008] Preferably, the guide rod passes through both sets of lifting frames.

[0009] Preferably, the two sets of threaded rods are respectively threadedly connected to the two sets of lifting frames.

[0010] Preferably, the two sets of grinding rollers are installed vertically, with the lower set of grinding rollers passing through the right wall of the fixing frame via a slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting a front abutment pad in conjunction with a rear abutment pad, this utility model can clamp multiple sets of spacers from the left and right sides to limit the multiple sets of spacers, so that the multiple sets of spacers can rotate synchronously, which facilitates the grinding and polishing of the inner and outer surfaces of the multiple sets of spacers by two sets of grinding rollers, thereby improving processing efficiency and ensuring the practicality of the device.

[0012] 1. This utility model, by setting a positioning structure, places the spacers on the top surface of the rotating roller and arranges the spacers from right to left, so that the last set of spacers fits against the left side wall of the rear abutment pad. The spacers are then fitted onto the outside of the lower set of grinding rollers. Rotating the rotating handle drives the threaded sleeve to rotate. The threaded sleeve is threadedly connected to the slot. When rotating the rotating handle, the threaded sleeve and the front abutment pad move to the right, so that the right side wall of the front abutment pad fits against the leftmost set of spacers. The front abutment pad, together with the rear abutment pad, can clamp and fix the left and right sides of multiple sets of spacers. When the rotating roller rotates, it drives the upper spacers to rotate through friction. The front abutment pad and the rear abutment pad can rotate synchronously under the action of the front abutment pad and the rear bearing, which can ensure the positioning effect of the spacers. 2. This utility model, by incorporating a grinding structure, allows for the activation of two sets of lifting motors, which in turn drive two sets of threaded rods to rotate. These threaded rods are threadedly connected to the lifting frame, and their rotation causes the lifting frame to move along the guide rod, resulting in both sets of lifting frames descending together. This allows two sets of grinding rollers to approach the top surface and the inner bottom surface of the spacer, respectively. Activating the grinding motors then drives the grinding rollers to rotate, which in turn grinds and polishes the inner and outer walls of multiple sets of spacers, thus improving the grinding efficiency of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides an embodiment of a precision grinding machine for the inner and outer circular planes of a slitting machine spacer: The fixed frame 1 and the rotating roller 11 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0017] A precision grinding machine for inner and outer circular planes of a slitting machine includes: a fixed frame 1, and a rotating roller 11 installed on the inner side of the fixed frame 1; The right end of the fixing frame 1 is provided with a slot 12, and the left end of the fixing frame 1 is provided with a threaded groove 13; A positioning structure 2 is installed on the fixed frame 1. The positioning structure 2 includes a threaded sleeve 21. The threaded sleeve 21 is movably installed on the inner side of the threaded groove 13 via a thread. A rotating handle 22 is fixedly connected to the left end of the threaded sleeve 21. A front abutment pad 24 is movably installed on the right end of the threaded sleeve 21 via a front bearing 23. A rear abutment pad 26 is movably installed on the right end of the fixed frame 1 via a rear bearing 25. A grinding structure 3 is installed on the right side of the fixed frame 1. The grinding structure 3 includes a fixed plate 31, which is fixedly installed on the right side wall of the fixed frame 1. A guide rod 32 is fixedly installed on the fixed plate 31. Two sets of lifting motors 33 are fixedly installed on the surface of the fixed plate 31. A threaded rod 34 is fixedly connected to the output end of the lifting motor 33. Two sets of lifting frames 35 are slidably installed on the guide rod 32. A grinding motor 36 is fixedly installed on the lifting frame 35. A grinding roller 37 is fixedly connected to the output end of the grinding motor 36. By setting a front abutment pad 24 and a rear abutment pad 26, multiple sets of spacers can be clamped from the left and right sides to limit the multiple sets of spacers and make the multiple sets of spacers rotate synchronously. This facilitates the grinding and polishing of the inner and outer surfaces of the multiple sets of spacers by the two sets of grinding rollers 37, improves processing efficiency, and ensures the practicality of the device.

[0018] Furthermore, the threaded sleeve 21 is adapted to the threaded groove 13, and the front abutment pad 24 and the rear abutment pad 26 are coaxially arranged. When the threaded sleeve 21 rotates, it can move laterally in the threaded groove 13. The front abutment pad 24, in conjunction with the rear abutment pad 26, can clamp and fix the multiple sets of spacers in the middle on the left and right sides.

[0019] Furthermore, the guide rod 32 passes through both sets of lifting frames 35, and the guide rod 32 serves as a guide and limit for the movement of the two sets of lifting frames 35.

[0020] Furthermore, the two sets of threaded rods 34 are threadedly connected to the two sets of lifting frames 35 respectively, and the rotation of the threaded rods 34 can drive the lifting frame 35 to move up and down.

[0021] Furthermore, the two sets of polishing rollers 37 are installed vertically, and the lower set of polishing rollers 37 passes through the right wall of the fixing frame 1 via the slot 12. The two sets of polishing rollers 37 can polish the inner and outer surfaces of the spacer.

[0022] Working principle: Before grinding, place the spacers on the top surface of the rotating roller 11 and arrange the spacers from right to left so that the last set of spacers fits against the left side wall of the rear abutment pad 26. The spacers are then fitted on the outside of the lower set of grinding rollers 37. Rotating the rotating handle 22 drives the threaded sleeve 21 to rotate. The threaded sleeve 21 is threadedly connected to the slot 12. When rotating the rotating handle 22, the threaded sleeve 21 and the front abutment pad 24 are moved to the right, so that the right side wall of the front abutment pad 24 fits against the leftmost set of spacers. The front abutment pad 24, together with the rear abutment pad 26, can clamp and fix the left and right sides of multiple sets of spacers. When the rotating roller 11 rotates, it drives the upper spacers to rotate through friction. The front abutment pad 24 and the rear abutment pad 26 can rotate synchronously under the action of the front abutment pad 24 and the rear bearing 25, which can ensure the positioning effect of the spacers. Starting the two sets of lifting motors 33 will drive the two sets of threaded rods 34 to rotate. The threaded rods 34 are threadedly connected to the lifting frame 35. The rotation of the threaded rods 34 will drive the lifting frame 35 to move on the guide rod 32, so that the two sets of lifting frames 35 will descend together. This will drive the two sets of grinding rollers 37 to approach the top surface and the inner bottom surface of the spacer respectively. Starting the grinding motor 36 will drive the grinding rollers 37 to rotate. The rotation of the grinding rollers 37 can grind and polish the inner and outer walls of multiple sets of spacers, improving the grinding efficiency of the device.
