Abstract
Description
Technical Field
[0001] This application belongs to the field of polishing cloth wheel manufacturing technology, and in particular relates to a tooling for clamp installation. Background Technology
[0002] In the production process of polishing cloth wheels, the installation of the clamps on the cloth wheel winding body is a key step affecting product accuracy. Traditionally, the process involves manually pre-winding starch-impregnated cloth onto a fixed mandrel, then transferring it to a winding machine where a wooden core is pressed into a cylindrical cloth wheel winding body. After drying and curing, metal clamps are manually installed one by one at equal intervals on the dried cloth wheel winding body surface. Currently, the installation and positioning of the clamps mainly rely on manual measurement. Operators need to repeatedly measure the distance between adjacent clamps using a tape measure, requiring repositioning after each clamp installation. This is inefficient, and repeated manual measurements can easily lead to accumulated errors, resulting in uneven tension along the cloth wheel axis. Utility Model Content
[0003] To address the shortcomings of the prior art, this application provides a clamp installation tool to simplify installation and positioning operations and improve installation accuracy and efficiency.
[0004] To achieve the above objectives, the present invention employs the following technology: A clamp installation tool is used to install clamps at equal intervals along the length of a cloth wheel winding body, comprising: The support mechanism includes a substrate and a pair of support blocks mounted on the top surface of the substrate. The two support blocks are moved synchronously towards each other along the length of the substrate. The top surfaces of the two support blocks are provided with placement grooves downward along the height of the substrate for placing the two ends of the cloth wheel winding body. A locking mechanism, located on the support block, is used to fix the cloth wheel winding body; A strip plate is mounted on the top surface of the substrate and arranged along its length. The center of the strip plate along its length is always located in the middle of the two support blocks. Multiple positioning holes are arranged in an array along the length of the strip plate on one side. The positioning block is set between the support block and the strip plate and is movable along the length of the substrate. One side of the positioning block is provided with a positioning pin that is elastically telescopic along the axis and has its far end facing the strip plate. The other side of the positioning block is provided with a pair of arc plates that are completely overlapped in projection along the length of the substrate. The side of the arc plates is perpendicular to the length of the substrate. The distance between the two arc plates is equal to the width of the clamp. The concave surface of the arc plate is used to abut against the outer surface of the cloth wheel winding body as the positioning block moves. The locating pin and each locating hole together form a flexible ball-head plunger locating pair structure.
[0005] The beneficial effects of this utility model are as follows: 1. By setting up positioning blocks, arc plates, and strip plates, and cooperating with the elastic ball-head plunger positioning pair structure formed between positioning pins and positioning holes, the arc plate can be quickly positioned to the installation position, effectively improving the installation efficiency of the clamp. 2. The positioning accuracy of the elastic ball-head plunger positioning pair is higher than that of manual measurement, which can effectively improve the installation accuracy of the clamp.

Detailed Implementation
[0011] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0012] like Figure 2 The main structure of the cloth wheel winding body 5 is shown, including a wooden core 51 and a cylindrical cloth 52 wound on the wooden core 51. The wooden core 51 and the cylindrical cloth 52 are coaxial, and both ends of the wooden core 51 extend out of the corresponding end face of the cylindrical cloth 52 by the same length.
[0013] This application provides a clamp installation tool for installing clamps at equal intervals along the length of the cylindrical fabric 52.
[0014] Specifically, such as Figures 1-4 As shown, the tooling in this embodiment includes: a support mechanism 1, a locking mechanism 2, a strip plate 3, a positioning block 4, etc.
[0015] Among them, such as Figures 1-3 As shown, the support mechanism 1 includes a base plate 11 and a pair of support blocks 12 mounted on the top surface of the base plate 11. The two support blocks 12 are arranged to move synchronously towards each other along the length direction of the base plate 11. The top surfaces of the two support blocks 12 are provided with placement grooves 13 downward along the height direction of the base plate 1, which are respectively used to place the two ends of the wood core 51.
[0016] like Figures 1-3 As shown, the locking mechanism 2 is mounted on the support block 12 and is used to fix both ends of the wooden core 51, thereby fixing the entire cloth wheel winding body. Specifically, as shown... Figure 3 As shown, the locking mechanism 2 can be made by using a tightening bolt 21 to form a through threaded engagement with one side of the support block 12, and the axis of the tightening bolt 21 is perpendicular to one side of the support block 12. By screwing the tightening bolt 21 into the placement groove 13, the end of the wood core 51 can be tightened against the inside of the placement groove 13. When the tightening bolts 21 on the two support blocks 12 tighten both ends of the wood core 51, the cloth wheel winding body 5 is fixed, and its length direction is the same as the length direction of the base plate 11. The axis of the tightening bolt 21 intersects the axis of the wood core 51 perpendicularly.
[0017] like Figures 1-3 As shown, the strip plate 3 is mounted on the top surface of the substrate 11 and arranged along its length direction. The center position of the strip plate 3 along its length direction is always located in the middle of the two support blocks 12. One side of the strip plate 3 faces the support block 12 and has multiple positioning holes 31 arranged in an array along its own length direction.
[0018] like Figure 1 and Figure 3 As shown, the positioning block 4 is mounted between the support block 12 and the strip plate 3 and is movable along the length of the base plate 11. One side of the positioning block 4 is opposite to one side of the strip plate 3, and it is provided with a positioning pin 41 that is elastically telescopic along the axis. The distal end of the positioning pin 41 faces the strip plate 3. Specifically, as shown... Figure 3 As shown, a mounting hole can be opened on one side of the positioning block 4 along the width direction of the substrate 11, and the positioning pin 41 can be axially slidably fitted into the mounting hole. A helical spring is axially arranged at the bottom of the hole, connecting the bottom of the hole and the near end of the positioning pin 41 to realize the elastic extension and contraction of the positioning pin 41. The helical spring is used to push the far end of the positioning pin 41 into the positioning hole 31. The other side of the positioning block 4 faces the support block 12 and is provided with a pair of arc plates 42 that are completely overlapped in projection along the length direction of the substrate 11. The sides of the two arc plates 42 are perpendicular to the length direction of the substrate 11. The distance between the two arc plates 42 is equal to the width of the clamp. The curvature of the arc plate 42 is adapted to the roundness of the cylindrical fabric 52. When the cloth wheel winding body 5 is in a fixed state, the distance between the axis of the wood core 51 and the concave surface of the arc plate 42 is equal to the radius of the cylindrical fabric 52. That is, the arc plate 42 can abut against the outer surface of the cylindrical fabric 52 as the positioning block 4 moves.
[0019] like Figure 3As shown, the positioning pin 41 and each positioning hole 31 constitute an elastic ball-head plunger positioning pair structure. Specifically, the distal end of the positioning pin 41 is a hemispherical head, and the positioning hole 31 is a spherical conical hole, that is, the edge of the positioning hole 31 is a conical surface, which is used to guide the ball head of the positioning pin 41 to slide in. The bottom of the positioning hole 31 is a spherical surface, which is used to precisely fit with the ball head of the positioning pin 41.
[0020] When applying, such as Figure 1 and Figure 2 As shown, the two ends of the wooden core 51 are placed in the placement groove 13, and the two support blocks 12 move closer to each other synchronously and abut against the corresponding end faces of the cylindrical fabric 52, thereby achieving the positioning of the fabric wheel winding body 5. Since the center position of the strip plate 3 along its length is always located in the middle of the two support blocks 12, the center position of the cylindrical fabric 52 along its length is also located in the middle of both ends of the strip plate 3. Figures 1-3 As shown, the tightening bolt 21 is used to tighten the end of the wood core 51, thereby fixing the cloth wheel winding body 5. Then, the positioning block 4 is moved so that the arc plate 42 enters between the cylindrical cloth 52 and the strip plate 3, and the concave surface of the arc plate 42 abuts against the surface of the cylindrical cloth 52. Whenever the ball head at the far end of the positioning pin 41 enters the positioning hole 31 and fits against the spherical surface of the bottom of the positioning hole 31, it is positioned to a clamp installation position. The operator inserts the clamp between the two arc plates 42 and wraps it around the cylindrical cloth 52 so that the clamp fits against its surface. Then the clamp is tightened to complete the installation of one clamp. Then the positioning block 4 is moved again so that the ball head of the positioning pin 41 fits with the next positioning hole 31 to complete the installation of the next clamp. The above operation is repeated to complete the overall installation of the clamps of the cylindrical cloth 52.
[0021] By setting up the positioning block 4, the arc plate 42, and the strip plate 3, and cooperating with the elastic ball-head plunger positioning pair structure formed between the positioning pin 41 and the positioning hole 31, the arc plate 42 can be quickly positioned to the installation position, which effectively improves the installation efficiency of the clamp; at the same time, the positioning accuracy of the elastic ball-head plunger positioning pair is higher than the accuracy of manual measurement, which can effectively improve the installation accuracy of the clamp.
[0022] Specifically, such as Figures 1-4As shown, a pair of guide posts 32 arranged vertically along the length direction are provided on the top surface of the substrate 11. The strip plate 3 has multiple specifications depending on its length. On the other side of each strip plate 3, there are two guide blocks 33 arranged along its length direction. Each guide block 33 slides and engages with the guide post 32 along the height direction of the substrate 11. A fixing component 34 is provided between the guide post 32 and the guide block 33 to fix a specific strip plate 3 at the engagement height of the positioning hole 31 and the positioning pin 41. In application, the strip plate 3 of the corresponding specification can be selected according to the length of the cylindrical fabric 52, so that the tooling can be applied to various specifications of fabric wheel winding bodies 5, improving the practicality of the tooling. At the same time, the fixing component 34 can be provided with a mating hole on the guide post 32 and a locking hole on the guide block 33. When the strip plate 3 is at the engagement height with the positioning pin 41, the mating hole and the locking hole coincide. At this time, the locking pin is inserted to fix the strip plate 3. Other detachable structures can also be used.
[0023] Specifically, such as Figure 1 As shown, a pair of first guide rods 14 are mounted on the base plate 11 along its length. Two movable blocks 15 slide through the first guide rods 14. The two movable blocks 15 are located below the support blocks 12 and are connected to the corresponding support blocks 12 via connecting rods 16. A bidirectional lead screw 17 is also mounted on the base plate 11 along its length. The two movable blocks 15 pass through the opposite ends of the threads of the bidirectional lead screw 17 and engage with its threads. A motor 18 is provided at one end of the base plate 11 to drive the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 drives the two support blocks 12 to move with high synchronization, which can accurately position the cylindrical fabric 52 and improve the reliability of the tooling.
[0024] Specifically, such as Figures 1-3 As shown, a pair of second guide rods 19 are mounted between the strip plate 3 and the support block 12 along the length of the base plate 11, and the positioning block 4 slides through the second guide rods 19.
[0025] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
