Description

Technical Field

[0001] This utility model relates to the field of sprocket processing equipment technology, and in particular to a positioning mechanism for a sprocket grinding processing device. Background Technology

[0002] As a key component in mechanical transmission, the machining and polishing of sprockets is an important step in ensuring transmission efficiency and service life. After the sprocket is machined, it needs to be polished. Polishing can not only remove surface burrs and tool marks, but also optimize the surface finish of the sprocket and reduce frictional resistance during operation.

[0003] Rough grinding of sprockets typically uses tools such as grinding wheels to quickly shape the sprocket. Fine grinding uses sandpaper, polishing paste, etc., to achieve the required surface roughness. For example, the Chinese utility model patent disclosed in announcement number CN213858474U, "A Sprocket Blank Grinding Device," uses the cooperation of a grinding plate and grinding parts within the grinding mechanism to grind the machine end face of the sprocket's inner hole. Simultaneously, by adjusting the position of the grinding plate and grinding parts, it can meet the grinding needs of sprockets with different hole diameters and thicknesses. However, during the sprocket grinding process, it is difficult to accurately fix sprockets of different specifications, leading to inconsistent grinding accuracy and potential sprocket deflection, thus affecting the grinding quality. Furthermore, switching between grinding different sprocket sizes involves cumbersome positioning and adjustment operations, consuming a significant amount of time and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for a sprocket grinding and processing device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A positioning mechanism for a sprocket grinding processing device includes a base, a limiting ring fixedly installed at the lower end of the base, an adjusting ring movably installed between the base and the limiting ring, a plurality of C-shaped fasteners fixedly installed on the outer side of the base, a bevel gear movably installed between the base and the C-shaped fasteners, a radial screw threadedly connected to the middle of the bevel gear, one end of the radial screw passing through the C-shaped fastener and extending to one side of the C-shaped fastener, and the other end of the radial screw passing through the base and extending into the base and fixedly installed with an end block, a support ring fixedly installed on the base, and a positioning seat threadedly connected to the support ring.

[0007] As a further preferred embodiment of this utility model, a fixing ring is fixedly installed on the limiting ring, the upper end of the fixing ring abuts against the lower end of the base, and the fixing ring and the base are fixedly connected by screws. Installing the limiting ring on the lower end of the base through the fixing ring provides conditions for the rotational installation of the adjusting ring.

[0008] As a further preferred embodiment of this utility model, the lower end of the adjusting ring is provided with a rotating groove, the adjusting ring is rotatably mounted on the outside of the fixed ring, the rotating groove is rotatably mounted on the limiting ring, a bevel gear ring is fixedly mounted on the adjusting ring, the bevel gear ring and multiple bevel gears cooperate to realize the synchronous radial movement of multiple radial screws, and an operating ring is fixedly mounted on the outside of the adjusting ring, the operating ring can realize the rotation operation of the adjusting ring by personnel.

[0009] As a further preferred embodiment of this utility model, the C-shaped fastener has a through hole, and a limiting block is fixedly installed at the top of the through hole. The setting of the limiting block can provide a limiting condition to prevent the radial screw from rotating synchronously with the bevel gear and thus achieving radial movement.

[0010] As a further preferred embodiment of this utility model, positioning rings are fixedly installed on both sides of the bevel gear. One positioning ring abuts against one side of the C-shaped fixing member, and the other positioning ring abuts against one side of the base. The bevel gear is meshed with the bevel gear ring. The positioning rings on both sides of the bevel gear can make the bevel gear rotate stably between the base and the C-shaped fixing member.

[0011] As a further preferred embodiment of this utility model, a limiting groove is formed on the outer side of the radial screw, and a limiting groove is formed on one side of the radial screw, with the limiting groove inserted into the limiting block.

[0012] As a further preferred embodiment of this utility model, an insert block is fixedly installed on one side of the end block relative to the radial screw. The insert block is inserted into the mounting groove and fixed with screws. A clamping rod is fixedly installed on the end block. V-shaped grooves are opened on both sides of the clamping rod. The inner side of the V-shaped groove is coated with a rubber layer. An end block is set on one side of the radial screw, and a clamping rod with double-sided V-shaped grooves is set on the end block. This allows the sprocket to be clamped and fixed or expanded and fixed from the inside of the shaft hole or the outside of the sprocket according to the grinding requirements.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, an adjusting ring with a bevel gear ring is rotatably installed at the lower end of the base, and multiple bevel gears are rotatably installed on the outer side of the base via multiple C-shaped fasteners. The bevel gears are internally threaded with radial screws. This allows the bevel gear ring to synchronously drive the multiple bevel gears to rotate when the adjusting ring is rotated, which in turn drives the multiple radial screws to move within the base. This allows the clamping rods on one end block of the multiple radial screws to quickly fix the sprocket from the shaft hole inside the sprocket or clamp and fix the sprocket from the outside.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 As shown, the positioning mechanism of the sprocket grinding processing device provided by this utility model includes a base 1, a limiting ring 2 fixedly installed at the lower end of the base 1, an adjusting ring 3 movably installed between the base 1 and the limiting ring 2, a plurality of C-shaped fixing parts 4 fixedly installed on the outside of the base 1, a bevel gear 5 movably installed between the base 1 and the C-shaped fixing parts 4, a radial screw 6 threadedly connected to the middle of the bevel gear 5, one end of the radial screw 6 passing through the C-shaped fixing parts 4 and extending to one side of the C-shaped fixing parts 4, and the other end of the radial screw 6 passing through the base 1 and extending into the base 1 and fixedly installed with an end block 7, a support ring 12 fixedly installed on the base 1, and a positioning seat 13 threadedly connected to the support ring 12.

[0022] like Figures 2-3As shown, a fixing ring 8 is fixedly installed on the limiting ring 2. The upper end of the fixing ring 8 abuts against the lower end of the base 1, and the fixing ring 8 and the base 1 are fixedly connected by screws. The limiting ring 2 is installed on the lower end of the base 1 through the fixing ring 8, so that the cooperation between the limiting ring 2, the fixing ring 8 and the base 1 provides conditions for the rotational installation of the adjusting ring 3. The lower end of the adjusting ring 3 has a rotating groove 9. The adjusting ring 3 is rotatably installed on the outside of the fixing ring 8, and the rotating groove 9 is rotatably installed on the limiting ring 2. A bevel gear ring 10 is fixedly installed on the adjusting ring 3. The cooperation between the bevel gear ring 10 and multiple bevel gears 5 can realize the synchronous radial movement of multiple radial screws 6. An operating ring 11 is fixedly installed on the outside of the adjusting ring 3. The operating ring 11 can realize the rotational operation of the adjusting ring 3 by personnel.

[0023] like Figure 4 As shown, a through hole 14 is provided inside the C-shaped fastener 4, and a limiting block 15 is fixedly installed at the top of the through hole 14. The setting of the limiting block 15 provides a limiting condition to prevent the radial screw 6 from moving radially while rotating synchronously with the bevel gear 5. Positioning rings 21 are fixedly installed on both sides of the bevel gear 5. One positioning ring 21 abuts against one side of the C-shaped fastener 4, and the other positioning ring 21 abuts against one side of the base 1. The bevel gear 5 is meshed with the bevel gear ring 10. The positioning ring 21 on each side of the bevel gear 5 allows the bevel gear 5 to rotate stably between the base 1 and the C-shaped fastener 4. The radial screw 6 has an outer opening A limiting groove 16 is provided, and a limiting groove 16 is opened on one side of the radial screw 6. The limiting groove 16 is inserted into the limiting block 15. An insert block 18 is fixedly installed on the end block 7 relative to the side of the radial screw 6. The insert block 18 is inserted into the mounting groove 17 and fixed with screws. A clamping rod 19 is fixedly installed on the end block 7. V-shaped grooves 20 are opened on both sides of the clamping rod 19. The inner side of the V-shaped grooves 20 is coated with a rubber layer. The end block 7 is set on one side of the radial screw 6, and the clamping rod 19 with double-sided V-shaped grooves 20 is set on the end block 7. This allows the sprocket to be clamped and fixed or expanded and fixed from the inside or outside of the shaft hole of the sprocket according to the grinding requirements.

[0024] It should be noted that this utility model is a positioning mechanism for a sprocket grinding processing device. In use, the positioning mechanism is first installed on the grinding equipment. Then, the sprocket is placed on the support ring 12, with the protruding part of the sprocket near the shaft hole inserted into the support ring 12. At this time, the operator rotates the operating ring 11 on the adjusting ring 3. The rotating groove 9 at the lower end of the adjusting ring 3 rotates on the limiting ring 2. Simultaneously, the adjusting ring 3 rotates around the fixed ring 8. Because a bevel gear ring 10 is fixed on the adjusting ring 3, the bevel gear ring 10 will drive the multiple bevel gears 5 meshing with it to rotate. When the bevel gears 5 rotate, the radial screw 6 threadedly connected to them, under the restriction of the limiting block 15 and the limiting groove 16, will not rotate with the bevel gears 5, but only... Moving radially, multiple radial screws 6 move synchronously, driving end blocks 7 to move towards the center point inside the base 1. This causes the clamping rods 19 on the multiple end blocks 7 to clamp and fix the protruding part of the lower end of the sprocket. At this time, the upper surface of the sprocket and the inner side of the shaft hole can be polished by the polishing mechanism. When it is necessary to polish the lower surface of the sprocket and the protruding part of the lower end of the sprocket, the sprocket can be rotated 180 degrees and placed on the support ring 12, so that the multiple clamping rods 19 are inserted into the shaft hole of the sprocket. At this time, the adjusting ring 3 can be rotated in the same way as above, so that the radial screws 6 drive the clamping rods 19 to abut against the inner side of the shaft hole of the sprocket through the end blocks 7, thereby fixing the sprocket from the inside.
