Description

Technical Field

[0001] This utility model relates to the field of speed reducer processing technology, and in particular to a high-efficiency positioning fixture for speed reducer assembly. Background Technology

[0002] In the field of speed reducer machining, the fixation and positioning of the workpiece is a crucial factor affecting machining accuracy and efficiency. Traditional fixing methods typically use a set of rigid clamps to hold the speed reducer housing. While this method is applicable to most speed reducers, some speed reducer housings are circular, and simple flat clamps cannot provide uniform clamping force. Furthermore, for certain special-structure circular speed reducers, such as stepped differential housings, the diameters at both ends are different, and a traditional set of clamps cannot fix both ends of the speed reducer housing. This can easily lead to the housing shifting or vibrating during machining, thereby reducing machining accuracy and potentially damaging the housing surface due to uneven force. Utility Model Content

[0005] A second positioning element is slidably mounted on the top of one side of the bracket. The second positioning element has the same structure as the first positioning element, and the two are mirror images of each other.

[0006] Furthermore, one end of the clamping plate is provided with a cylindrical head integrally formed therewith and an extrusion cover surrounding the cylindrical head, and a plurality of evenly distributed connecting springs are fixedly installed between the cylindrical head and the extrusion cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Traditional fixing methods typically use a set of rigid clamps to hold the reducer housing. While this method is applicable to most reducers, some reducer housings are circular, and simple flat clamps cannot provide uniform clamping force. Furthermore, for some special circular reducers, such as stepped reducers with different diameters at both ends, the traditional set of clamps cannot fix both ends of the reducer housing. This can easily lead to the housing shifting or vibrating during processing, thereby reducing processing accuracy and potentially damaging the housing surface due to uneven force.

[0023] To address the problems encountered by the aforementioned fixing method when fixing a reducer with a circular housing, please refer to [link / reference needed]. Figures 1-5This utility model provides a high-efficiency positioning fixture for assembling speed reducers. It can not only fix speed reducers with circular housings of different specifications, but also special circular housing speed reducers with different diameters at both ends, optimizing the fixing effect of the equipment on circular housing speed reducers. The positioning fixture uses a bracket 1 as a base. A first positioning element 2 is fixedly installed at the bottom of one side of the bracket 1 to fix the lower end of the housing. The first positioning element 2 is a processing plate 21 fixedly connected to the side of the bracket 1. Multiple rotating shafts 22, evenly distributed circumferentially along their axis, are rotatably mounted on the top of the processing plate 21. A clamping plate 23 is fixedly sleeved on the outer surface of the rotating shaft 22, and the lower end of the rotating shaft 22 passes through the processing plate 21 and is fixedly connected to a driven gear 24. A support column 25 is rotatably mounted at the center of the bottom of the processing plate 21. An active gear 26, meshing with multiple driven gears 24, is fixedly sleeved on the outer surface of the support column 25. Rotating the support column 25 drives the active gear 26 to rotate, and the rotation of the active gear 26 drives multiple driven gears 24. The rotating gear 24 drives the rotating shaft 22 to rotate, which in turn drives multiple clamping plates 23 to rotate synchronously. The rotation of the clamping plates 23 can clamp and fix the circular shell on the processing plate 21. By adjusting the rotation angle of the clamping plates 23, the diameter of the circle formed by the multiple clamping plates 23 can be adjusted, thus enabling the clamping of circular shells with different diameters. A second positioning element 3 is slidably arranged on the top of one side of the bracket 1. The second positioning element 3 has the same structure as the first positioning element 2 and the two are mirror images of each other. During processing, even if the diameters of the two ends of the circular shell are different, the first positioning element 2 and the second positioning element 3 can fix the upper and lower ends of the circular shell respectively, achieving stable clamping of the shell and ensuring the accuracy of processing.

[0024] To facilitate control of the rotation of the support column 25, an equipment frame 27 is fixedly connected to the edge of the processing plate 21. The equipment frame 27 is equipped with a driving component 28 that acts on the support column 25. The driving component 28 includes a first motor 281 fixedly installed on one side of the bottom of the equipment frame 27. A first pulley 282 is fixedly installed at the output end of the first motor 281. A second pulley 283 is fixedly sleeved on the lower end of the support column 25. A synchronous belt 284 is provided on the outside of the second pulley 283 and the first pulley 282. Driving the first motor 281 can drive the first pulley 282 to rotate. The rotation of the first pulley 282 can drive the second pulley 283 to rotate through the synchronous belt 284, thereby driving the support column 25 to rotate, realizing the synchronous rotation of multiple clamping plates 23 for fixing the circular shell.

[0025] In actual processing, the height of circular shells of different specifications often varies. In order for the equipment to be applicable to circular shells of different heights, a lead screw 4 is rotatably installed inside the bracket 1. The second positioning component 3 is set on the lead screw 4. The processing plate in the second positioning component 3 is threaded onto the outside of the lead screw 4, and the processing plate in the second positioning component 3 is slidably connected to the bracket 1. A second motor 5 that acts on the lead screw 4 is fixedly installed at the upper end of the bracket 1. Driving the second motor 5 can drive the lead screw 4 to rotate. The rotation of the lead screw 4 can drive the processing table in the second positioning component 3 to slide up and down along the bracket 1, thereby adjusting the distance between the second positioning component 3 and the first positioning component 2, so as to achieve clamping and fixing of circular shells of different heights.

[0026] Example 2

[0027] When clamping the circular outer shell, excessive clamping force can easily cause compression and deformation of the shell. To avoid this problem, please refer to... Figure 5 As shown, a cylindrical head 231 integrally formed with the clamping plate 23 is provided at one end, and an extrusion cover 232 surrounds the cylindrical head 231. Multiple evenly distributed connecting springs 233 are fixedly installed between the cylindrical head 231 and the extrusion cover 232. A rubber layer 234 is fixedly provided on the outer surface of the extrusion cover 232. In this way, when the clamping plate 23 clamps the shell, the rubber layer 234 can contact the shell first. The surface hardness of the rubber layer 234 is low, so it will not scratch the shell. The extrusion cover 232 is used to support the rubber layer 234 and provide effective clamping force for the shell. As the rubber layer 234 extrudes the shell, the connecting springs 233 will deform. The reaction force of the connecting springs 233 can be transmitted to the shell to provide clamping force for the shell. The connecting springs 233 can provide a certain amount of movement space for the extrusion cover 232, avoiding direct hard contact between the extrusion cover 232 and the shell and causing damage to the shell. While fixing the shell, it also plays a protective role for the shell.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
