Description

Technical Field

[0001] This utility model relates to the field of grinding wheel disassembly and assembly technology for strip grinding machines, specifically to a grinding wheel jamming disassembly and assembly device for strip grinding machines. Background Technology

[0002] On the strip steel rolling production line, the strip grinding machine is a key finishing equipment. The regular disassembly and maintenance of its grinding wheel assembly directly affects the continuity of the production line and the quality of the products. The current disassembly and assembly of the grinding wheel flange generally involves removing the flange fixing bolts, inserting two 6mm Allen wrenches into the holes on the side of the flange, and turning the Allen wrenches with both hands to disassemble and assemble the flange.

[0003] This approach will cause the following problems:

[0004] Dynamic locking defect: During disassembly and assembly, the grinding wheel rotates freely with the applied force, causing the flange to fail to reach the effective pre-locking torque, resulting in a 20-35% loss of locking force. After rotating the grinding wheel, there is a risk of the grinding wheel breaking.

[0005] Operational mechanical imbalance: When operating a 6mm Allen wrench with both hands, if the angle of force applied by the worker deviates by more than ±15°, it is very easy for the tool to slip off, causing the worker to fall and injure himself, as well as posing a secondary risk of injury from tool fragments.

[0006] Labor time loss: A single disassembly and assembly operation takes up to 35-40 minutes, of which 40% of the time is spent on disassembling and assembling the grinding wheel flange.

[0007] Therefore, there is an urgent need to design a grinding wheel clamping and disassembly device for belt grinders to solve the problems of existing technology being unable to lock the grinding wheel, tools easily slipping out, causing safety risks to workers, and time-consuming disassembly and assembly with low work efficiency. Utility Model Content

[0008] In view of the problems existing in the prior art, the purpose of this utility model is to provide a device for disassembling and assembling the grinding wheel jamming of a strip grinding machine.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a grinding wheel jamming and disassembly device for a strip grinding machine, including a grinding wheel jamming component and a flange disassembly and assembly component. The grinding wheel jamming component includes a fixed bracket and a locking bolt. The fixed bracket has threaded holes on both sides of the lower part, and the locking bolt is connected to the threaded hole. The inner side of the locking bolt presses against and locks the grinding wheel. The flange disassembly and assembly component includes a lifting ring, a positioning bolt and a force-applying rod. The positioning bolt is welded to the bottom of the lifting ring, and the force-applying rod passes through the lifting ring to apply force.

[0010] Specifically, the fixing bracket is fixedly connected to the outside of the grinding wheel by bolts, and threaded holes are provided on both sides of the fixing bracket.

[0011] Specifically, the locking bolts are symmetrically arranged in the threaded holes on both sides of the fixed bracket.

[0012] Specifically, there are two lifting rings, which are welded together with the positioning bolts, and the size of the lifting rings is larger than the size of the force-applying rod.

[0013] Specifically, the positioning bolts are screwed diagonally into the threaded holes of the flange.

[0014] Specifically, the force-applying rod is an iron bar that passes through two lifting rings to apply force to the flange to achieve the required torque.

[0015] This utility model has the following beneficial effects:

[0016] The grinding wheel locking and disassembly device designed in this utility model can eliminate the failure of the grinding wheel assembly locking, avoid the problem that the grinding wheel assembly cannot reach the expected torque due to the force of the shaft rotation during disassembly and assembly; avoid the secondary risks of tool slippage, operator injury, and tool splash injury; make disassembly and assembly of the grinding wheel more convenient, reduce the time by 15 minutes, and improve work efficiency.

[0019] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] like Figure 1 As shown, a grinding wheel jamming and disassembly device for a strip grinder includes a grinding wheel jamming component and a flange disassembly and assembly component. The grinding wheel jamming component includes a fixed bracket 1 and a locking bolt 1.1. The fixed bracket 1 has threaded holes on both sides at the lower part. The locking bolt 1.1 passes through the threaded holes to lock the grinding wheel 3. The flange disassembly and assembly component includes a lifting ring 2, a positioning bolt 2.1 and a force-applying rod 2.2. The positioning bolt 2.1 is welded to the bottom of the lifting ring 2, and the force-applying rod 2.2 passes through the lifting ring 2 to apply force.

[0021] The fixed bracket 1 is fixedly connected to the outer shell of the grinding wheel 3 by bolts. The fixed bracket 1 has threaded holes on both sides for the locking bolt 1.1 to pass through. The fixed bracket 1 is used to fix the locking bolt 1.1 and the grinding wheel 3.

[0022] The locking bolt 1.1 consists of two bolts, which are inserted into the threaded holes. The locking bolt 1.1 is used to lock the grinding wheel 3 to prevent the grinding wheel 3 from rotating during the disassembly and assembly of the flange 4, and to lock and prevent the grinding wheel 3 from being jammed.

[0023] The lifting ring 2 and the positioning bolt 2.1 are welded together as a whole. There are two lifting rings 2 and two positioning bolts 2.1. The lifting ring 2 is used to pass through the force bar 2.2, and the positioning bolt 2.1 is used to fix the lifting ring 2 to the flange 4 on the outside of the grinding wheel 3. The positioning bolt 2.1 is installed diagonally in the bolt holes on the flange 4.

[0024] The lever 2.2 is a long iron rod. The size of the lever 2.2 is smaller than the inner diameter of the lifting ring 2. When using it, insert the lever 2.2 into the holes of the two lifting rings 2, grasp both ends of the lever 2.2, and apply force to the flange 4 until the required torque is achieved.
