Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically, particularly relates to a coupling processing fixture. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. During the processing of the coupling, it is usually necessary to cut and weld the coupling, which requires the coupling to be fixed and clamped.

[0003] After searching, for example, the patent with patent number CN220372715U discloses a coupling processing fixture, which relates to the field of coupling technology, including a base; a workbench is fixedly installed on the base, and a sliding mouth is provided in a circular array on the workbench, and sliders are slidably installed in the sliding mouths, and clamps are fixedly installed on the sliders, and a threaded rod is rotatably installed in the workbench, and a sliding sleeve is screwed on the threaded rod, and connecting rods are hinged on the side wall surface of the sliding sleeve, and the other end of the connecting rod is hinged to the slider, which effectively solves the technical problems that the existing coupling fixture is inconvenient to adjust and use according to coupling components of different sizes and has a small scope of application.

[0004] The processing fixture in the above patent still has the following shortcomings:

[0005] In the process of turning the coupling, due to different processing positions, different areas of the coupling sometimes need to be processed, and the parts that can be clamped by the current processing fixtures are usually fixed. If it is necessary to process the part where the coupling and the fixture contact, it will cause certain troubles and cannot meet different processing needs. Utility Model Content

[0006] In order to solve the above technical problems at least to a certain extent, the utility model provides a coupling processing fixture.

[0007] The purpose and effect of the coupling processing fixture of the utility model are achieved by the following specific technical means:

[0009] Furthermore, two groups of collecting troughs are fixedly arranged on the inner top of the base, and the collecting troughs adopt an inverted cone shell structure; an exhaust fan is fixedly arranged in the middle of the bottom of the collecting trough; and a slide rail is fixedly arranged on the top of the base.

[0010] Furthermore, a motor is fixedly arranged on the rear side of the slide rail; a bidirectional lead screw is rotatably arranged on the inner side of the slide rail, and the bidirectional lead screw is transmission-connected to the motor; a group of sliders with a rectangular block structure are slidably arranged on both the front and rear sides of the top of the slide rail, and both groups of sliders are connected to the bidirectional lead screw through threaded cooperation, and a fixing ring is fixedly arranged on the top of the slider.

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0024] Embodiment 1:

[0025] like Figures 1 to 6 As shown:

[0026] The present embodiment provides a coupling processing fixture, including: a base 1; the base 1 adopts a rectangular groove structure, and the top of the base 1 is provided with a through-type through-hole structure in a rectangular array; two groups of circular ring-shaped fixing rings 107 are arranged on the top of the base 1, a circular ring-shaped groove structure is opened on one side of the fixing ring 107, and four groups of rectangular slide groove structures are opened on the outer side of the fixing ring 107 in a circular array; the four groups of rectangular slide grooves on the outer side of the fixing ring 107 are slidingly arranged in four groups of rectangular block structures in a circular array, and the outer side surface of the driven block 109 is provided with a threaded groove structure, and the inner side surface of the driven block 109 is provided with a T-shaped slide groove structure; the inner end of the driven block 109 is fixedly provided with a clamping plate 110 with an arc plate structure.

[0027] Among them, a motor 104 is fixedly arranged on the rear side of the slide rail 103; a bidirectional lead screw 105 is rotatably arranged on the inner side of the slide rail 103, and the bidirectional lead screw 105 is transmission connected to the motor 104; a group of sliders 106 with a rectangular block structure are slidably arranged on both the front and rear sides of the top of the slide rail 103, and the two groups of sliders 106 are connected to the bidirectional lead screw 105 through threaded cooperation, and a fixing ring 107 is fixedly arranged on the top of the slider 106.

[0028] Among them, a control ring 108 with a circular structure is rotatably arranged in the circular groove on one side of the fixed ring 107, and a threaded groove structure is provided on one side of the control ring 108, and the control ring 108 is connected to the four groups of driven blocks 109 by threaded cooperation; a sliding plate 111 with an arc plate structure is slidably arranged in the T-shaped groove on the inner side of the driven block 109, and a through-type screw hole structure is provided on one side of the sliding plate 111; a control screw 112 is rotatably arranged in the T-shaped groove on the inner side of the driven block 109, and the control screw 112 is connected to the sliding plate 111 by threaded cooperation.

[0029] The specific usage and function of this embodiment are as follows:

[0030] During use, when processing the two ends of the coupling, the distance between the two sets of sliders 106 and the two sets of fixed rings 107 is adjusted according to the length of the coupling to be processed, and the two-way lead screw 105 is driven to rotate by starting the motor 104, thereby driving the two sets of sliders 106 and the fixed ring 107 to move toward each other along the slide rail 103. After adjusting to the appropriate distance, the workpiece to be processed is passed through the inner side of the two sets of fixed rings 107, and then the two sets of control rings 108 are rotated respectively. During the rotation of the control ring 108, through the cooperation with the threaded groove on one side of each set of driven blocks 109, each set of driven blocks 109 can be synchronously driven to slide along each set of slide grooves on the fixed ring 107, so that the outer side of the coupling is fixedly clamped by the clamping plate 110 at the inner end of each set of driven blocks 109, so as to achieve the coupling. For the purpose of fixing, the processing can be carried out. When the outer wall of the coupling needs to be processed, the position of each group of clamping plates 110 can be adjusted according to the diameter of the coupling, so that the outer wall of each group of clamping plates 110 is in a position that fits the inner wall of the coupling, and then the distance between each group of sliding plates 111 and the clamping plates 110 is adjusted according to the thickness of the coupling. The corresponding group of sliding plates 111 is driven by rotating the control screw 112 to slide along the T-shaped groove on the outside of the driven block 109, and the two ends of the coupling are fixedly clamped and limited by the cooperation of the clamping plates 110 and the sliding plates 111. Then the outer wall of the coupling can be processed without obstruction. Through the cooperation of the two processing methods, it is more convenient to process different positions of the coupling, meet different processing needs, and facilitate operation and use.

[0033] Among them, two groups of collecting tanks 101 are fixedly arranged on the inner top of the base 1, and the collecting tanks 101 adopt an inverted cone shell structure; an exhaust fan 102 is fixedly arranged in the middle of the bottom of the collecting tank 101; and a slide rail 103 is fixedly arranged on the top of the base 1.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In the utility model, the debris generated during the processing can be sucked into the base 1 through the rectangular through holes on the top of the base 1 and then dropped into the collecting trough 101 by starting two sets of exhaust fans 102. The iron chips can then be quickly sucked into the base 1 through the rectangular through holes on the top of the base 1 and dropped into the collecting trough 101. The iron chips can then be collected and recycled in a unified manner without causing the iron chips to remain on the top of the base 1 and affect the processing.
