Description

Technical Field

[0001] This utility model relates to the field of polishing cloth wheel processing technology, and in particular to a clamping fixture for cloth wheel processing. Background Technology

[0002] When making polishing cloth wheels, the cloth is first coated with adhesive and then wrapped around the wooden core. After wrapping, in order to ensure that the cloth between each cloth wheel is tightly bonded, it needs to be tightened with clamping rings. However, the clamping rings currently used are independently set, so the spacing between the clamping rings is inconsistent when fixing, which affects the binding effect. In addition, the width of the clamping rings currently used is smaller than the thickness of the cloth wheel, resulting in poor binding effect in some parts of the cloth wheel. Utility Model Content

[0003] This utility model provides a fastening fixture for processing cloth wheels, which solves the shortcomings of the prior art and the problems existing in the production of cloth wheels, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A fastening fixture for processing cloth wheels includes a pair of end plates. An upper horizontal plate is formed on the upper end of the end plates. A pair of connecting rods are respectively passed through both ends of the upper horizontal plate. Nuts are threaded to the outer ends of the connecting rods, and the inner ends of the nuts abut against the outer wall of the upper horizontal plate. The connecting rod is provided with tightening mechanisms arranged in an equally spaced array along its length, and the distance between two adjacent tightening mechanisms is equal to the thickness of the cloth wheel.

[0005] Furthermore, the tightening mechanism includes a connecting plate welded or pinned to the connecting rod. A pair of lower extension arms are fixed to both ends of the connecting plate by screws. A pair of guide rods pass through the lower extension arms. A tightening plate is fixed to the inner end of each pair of guide rods on the same side by screws. An arc-shaped groove is formed on the inner side of the tightening plate. Inner blocks are formed at the upper and lower ends of the inner end of the tightening plate. A pair of inner top inclined plates are welded to the outer side of the tightening plate. The upper end of the outer wall of the inner top inclined plate extends inward at an inward angle. A lead screw is threaded onto the connecting plate. A rotating head is provided at the upper end of the lead screw. A lower pressure plate is rotatably provided at the lower end of the lead screw. A pair of limiting rings are fixed to the lower end of the lead screw by pins. The limiting rings are located on the upper and lower sides of the lower pressure plate. Lower pressure arms are fixed to both ends of the lower pressure plate by screws. A strip-shaped hole is provided on the lower pressure arm. A guide rod at the upper end passes through the strip-shaped hole. A pair of pressure rollers are rotatably provided at the lower end of the lower pressure arm via a rotating shaft. The outer circumference of the pressure rollers abuts against the inclined surface of the inner top inclined plate.

[0006] Furthermore, a guide rod is threadedly connected to the inner wall of one side of the inner block, and the guide rod is inserted into another inner block located at the same height.

[0007] Furthermore, an arc-shaped fastening element is fixed to the inner block by screws, and the outer wall of the fastening element abuts against the groove.

[0008] The advantages of the above technical solution are: The tightening member provided by this utility model has a width that is similar to the width of the cloth wheel, thereby improving the compaction effect on the cloth after tightening.

[0009] Secondly, the spacing between each tightening mechanism is constant, and the tightening mechanism is fixed on the cloth wheel by two end plates, thereby ensuring that a dense cloth wheel can be processed at the position tightened by each tightening mechanism.

[0010] Thirdly, the tightening process is carried out by simultaneously tightening on both sides to ensure the effectiveness of the tightening. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0013] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0014] like Figures 1-2 As shown, a fastening fixture for processing cloth wheels includes a pair of end plates 3. An upper horizontal plate 30 is formed on the upper end of the end plate 3. A pair of connecting rods 31 are respectively passed through both ends of the upper horizontal plate 30. Nuts 32 are threadedly connected to the outer ends of the connecting rods 31. The inner ends of the nuts 32 abut against the outer wall of the upper horizontal plate 30.

[0015] The connecting rod 31 is provided with tensioning mechanisms 4 arranged in an equally spaced array along its length direction, and the distance between two adjacent tensioning mechanisms 4 is equal to the thickness of the cloth wheel.

[0016] The fastening mechanism 4 includes a connecting plate 55 welded or pinned to the connecting rod 31. A pair of lower extension arms 40 are fixed to both ends of the connecting plate 55 by screws. A pair of guide rods 41 pass through the lower extension arms 40. A fastening plate 45 is fixed to the inner end of each pair of guide rods 41 on the same side by screws. An arc-shaped groove is formed on the inner side of the fastening plate 45. Inner blocks 47 are formed at the upper and lower ends of the inner end of the fastening plate 45. A pair of inner top inclined plates 48 are welded to the outer side of the fastening plate 45. The upper end of the outer wall of the inner top inclined plates 48 extends inward at an inward angle. The connecting plate 55 has a through-hole... A lead screw 42 is threadedly connected to the inner block 47. A rotating head 43 is located at the upper end of the lead screw 42, and a downward pressing plate 44 is rotatably mounted at the lower end of the lead screw 42. A pair of limiting rings are fixed to the lower end of the lead screw 42 by pins, and the limiting rings are located on the upper and lower sides of the downward pressing plate 44. Downward pressing arms 49 are fixed to both ends of the downward pressing plate 44 by screws. A strip-shaped hole 50 is opened on the downward pressing arm 49, and a guide rod 41 at the upper end passes through the strip-shaped hole 50. A pair of pressure rollers 51 are rotatably mounted on the lower end of the downward pressing arm 49 via a rotating shaft 52. The outer circumference of the pressure rollers 51 abuts against the inclined surface of the inner top inclined plate 48. A guide rod is threadedly connected to the inner wall of one inner block 47, and the guide rod is inserted into another inner block 47 located at the same height. An arc-shaped fastening member 46 is fixed to the inner block 47 by screws, and the outer wall of the fastening member 46 abuts against a groove.

[0017] In this embodiment, the operator puts the end plate 3 on the inner core 1. Before putting it on, the cloth roll 2 and the inner core 1 are placed between each pair of fastening members 46. When putting on the end plate 3, the upper horizontal plate 30 is put on the connecting rod 31. After putting it on, the inner wall of the end plate 3 is made to abut against both ends of the cloth roll 2 by tightening the nut 32.

[0018] Then, the operator rotates each lead screw 42 in sequence, so that the lead screw 42 drives the lower pressure plate 44 to move downward. During the movement, the pressure roller 51 will abut against the inner wall of the inner top inclined plate 48, so that the inner top inclined plate 48 and the fastening member 46 move inward along the axial direction of the guide rod 41, and finally the inner wall of the fastening member 46 abuts against the outer periphery of the fabric roll 2. After a period of rest or by heating, the fabric rolls 2 are bonded together. This tightening method has a fixed clamping distance, which can ensure the compaction effect of the fabric roll 2.
