Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to a clamp for coupling processing. Background Art

[0002] A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque. It is sometimes also used to connect the shaft with other parts (such as gears, pulleys, etc.). It is often composed of two halves, which are connected by keys or tight fits, fastened to the two shaft ends, and then connected in some way. Most commonly used couplings have been standardized or normalized. In general, you only need to correctly select the type of coupling and determine the model and size of the coupling. Couplings can be divided into two categories: rigid couplings and flexible couplings. Rigid couplings do not have the ability to buffer and compensate for the relative displacement of the two axes, and require the two axes to be strictly aligned, but this type of coupling has a simple structure, low manufacturing cost, and assembly and disassembly. During production and processing, couplings usually require the use of different tooling fixtures to fix the couplings and then process them.

[0003] The existing technology has the following problems:

[0004] The existing coupling processing fixture is not convenient for stably moving the support plates when in use, which affects the clamping effect on both ends of the coupling; the existing coupling processing fixture is not convenient for stably clamping the two ends of couplings of different thicknesses when in use, which affects the retraction effect of the coupling. Utility Model Content

[0005] The utility model provides a clamp for machining a coupling to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A further improvement of the technical solution of the utility model is that: the inner wall of the slider seat is rotatably connected with a cam, and the outer wall of the cam is slidably connected to one side of the guide bar.

[0026] In this embodiment, the reverse double-threaded adjusting screw 2 is rotated by a tool, so that the distance between the slider seat 22 and the slider seat 22 can be adjusted under the action of the threaded connection, thereby adjusting the distance between the support plate 3 and the support plate 3, and the coupling 4 can be placed between the wear-resistant rubber plate 38 and the wear-resistant rubber plate 38 at one end of the arched support plate 33, and the adjusting screw 31 can be rotated by a tool, so that the support plate 34 can be moved outward under the action of the threaded connection, and the inner wall of the arched support plate 33 can be moved toward the axis of the coupling 4 under the action of the sliding connection between the support plate 34 and the arched support plate 33, so that the two ends of the outer wall of the coupling 4 can be locked to facilitate the processing of the coupling 4. Example

[0027] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the two layers on the top of the front side of the slider seat 22 are rotatably connected with wear-resistant steel balls 23, the bottom of the outer wall of the wear-resistant steel balls 23 is slidably connected to the top of the processing platform 1, the inner wall of the slider seat 22 is rotatably connected with a cam 24, and the outer wall of the cam 24 is slidably connected to one side of the guide bar 21.

[0028] In this embodiment, the wear of the connection between the top of the inner wall of the slider seat 22 and the top of the processing platform 1 is reduced by the action of the wear-resistant steel ball 23, and the wear between the two layers of the inner wall of the slider seat 22 and the two sides of the processing platform 1 is reduced by utilizing the sliding connection between the cam 24 and the guide bar 21, thereby improving the service life of the connection between the slider seat 22 and the processing platform 1. Example

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the edge of the support plate 34 is slidably connected to one side of the arched support plate 33, a rubber protective pad 35 is fixedly installed on one side of the support plate 3 and located at one end of the coupling 4, a guide rod 32 is fixedly installed on the front of the support plate 3 and located on the outer wall of the adjusting screw 31, the outer wall of the guide rod 32 is movably connected to the middle part of the support plate 34, a C-shaped spring piece 36 is fixedly installed between the bottom of one side of the arched support plate 33 and the two sides of the upper surface of the pressure plate 37, a rubber protective pad 35 is fixedly installed in the middle of the upper surface of the pressure plate 37, and the top of the outer wall of the rubber protective pad 35 is rotatably connected to the front of the arched support plate 33.

[0030] In this embodiment, the guide rod 32 is used to guide the support plate 34 to prevent it from rotating when the support plate 34 is moved. The rubber protective pad 35 is used to prevent the end of the coupling 4 from colliding with one side of the support plate 3 when the coupling 4 is clamped, thereby preventing damage to the coupling 4. The rubber protective pad 35 and the C-shaped spring clip 36 are used to facilitate the connection between the top of the pressure plate 37 and the bow support plate 33, so that one side of the wear-resistant rubber plate 38 fits tightly against the outer wall of the coupling 4, thereby improving the clamping effect on both ends of the outer wall of the coupling 4.

[0031] The following is a detailed description of the working principle of the coupling processing fixture.

[0032] like Figure 1-4 As shown, first, according to the length of the coupling 4, the reverse double-threaded adjusting screw 2 is rotated by a tool, so that the distance between the slider seat 22 and the slider seat 22 can be adjusted under the action of the threaded connection. When the slider seat 22 is moved, the wear of the connection between the top of the inner wall of the slider seat 22 and the top of the processing platform 1 is reduced by the action of the wear-resistant steel ball 23, and the wear between the two layers of the inner wall of the slider seat 22 and the two sides of the processing platform 1 is reduced by the action of the sliding connection between the cam 24 and the guide bar 21, thereby improving the service life of the connection between the slider seat 22 and the processing platform 1. The distance between the support plate 3 and the support plate 3 is adjusted, and the coupling 4 can be placed between the wear-resistant rubber plate 38 at one end of the arch support plate 33 and the wear-resistant rubber plate 38, and the adjusting screw 31 can be rotated by a tool, so that the support plate 3 can be adjusted under the action of the threaded connection. The support plate 34 moves outward, and the inner wall of the arched support plate 33 is moved toward the axis of the coupling 4 under the action of the sliding connection between the support plate 34 and the arched support plate 33, so that the two ends of the outer wall of the coupling 4 can be locked, and the guide rod 32 is used to guide the support plate 34 to avoid rotation when the support plate 34 is moved. At the same time, the rubber protection pad 35 is used to avoid the end of the coupling 4 from colliding with one side of the support plate 3 when the coupling 4 is clamped, causing damage to the coupling 4. At the same time, the rubber protection pad 35 and the C-shaped spring piece 36 are used to facilitate the connection between the top of the pressure plate 37 and the arched support plate 33, so that one side of the wear-resistant rubber plate 38 is tightly fitted on the outer wall of the coupling 4, thereby improving the clamping effect on the two ends of the outer wall of the coupling 4, so as to better process the coupling 4.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
