Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a ring-shaped product internal support positioning tooling. Background Technology

[0002] Positioning fixtures are unified mechanisms for positioning and clamping objects. During the processing of ring-shaped products, positioning fixtures are needed to fix the ring-shaped products in order to ensure the stability of the processing.

[0003] In the prior art, a Chinese utility model patent discloses a positioning fixture for processing ring-shaped workpieces (publication number: CN222200454U), which discloses an adjustment component and a rotation component. The positioning fixture for processing ring-shaped workpieces can quickly adjust the distance between two ring-shaped positioning plates through the adjustment component, thereby positioning and fixing the ring-shaped workpiece, which can improve processing stability. The rotation component can make the two movable positioning plates rotate, so that when processing a large number of ring-shaped workpieces of the same size, it is not necessary to frequently adjust the two ring-shaped positioning plates when changing the ring-shaped workpiece to be processed, thereby improving processing efficiency.

[0004] In the aforementioned prior art, the outer surface of the object is positioned and clamped. When the outer surface of the object is processed, it will block the outer surface of the object, making it difficult to process the outer surface of the object completely and easily resulting in processing defects.

[0005] Therefore, this utility model provides a ring-shaped product internal support positioning fixture to solve the above problems. Utility Model Content

[0006] This utility model provides a ring-shaped product internal support positioning fixture, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped product internal support positioning fixture, including a support frame, a driving mechanism and a positioning mechanism are provided on the top of the support frame;

[0008] The positioning mechanism includes two cross plates, both of which are rotatably connected to the top of the support frame. A threaded sleeve is provided on the top of the cross plate, and a threaded rod is threadedly connected to the inner wall of the threaded sleeve. A pressure plate is provided on the outer wall of the threaded rod, and a lifting sleeve is connected to the bottom of the pressure plate. The inner wall of the lifting sleeve is slidably connected to the outer wall of the threaded sleeve. Multiple first unfolding plates are fixedly connected at equal intervals to the outer wall of the lifting sleeve.

The top of the slider is connected to the bottom of the arc-shaped clamping plate, and both the inner wall of the sliding groove and the outer wall of the slider are polished.

[0010] As a further optimization, the outer wall of the threaded rod is rotatably connected to the inner wall of the pressure plate, and a knob is fixedly connected to the top end of the threaded rod.

[0011] As a further optimization, the drive mechanism includes a motor, which is fixedly connected to the bottom of the inner wall of the support frame. The output end of the motor is driven by a first synchronous pulley, which is driven by a second synchronous pulley via a synchronous belt. The inner walls of the first and second synchronous pulleys are driven by rotating rods, and the outer walls of the two rotating rods are rotatably connected to the inner walls of the two cross plates, respectively.

[0012] As a further optimization, a first bearing seat is fixedly connected to the bottom of the cross plate, and a bearing is provided inside the first bearing seat. The first bearing seat is rotatably connected to the rotating rod through the bearing.

[0013] As a further optimization, a second bearing seat is fixedly connected to the bottom of the inner wall of the support frame. The second bearing seat is rotatably connected to the stabilizer rod through a bearing. The outer wall of the stabilizer rod is connected to the inner wall of the second synchronous wheel. A support plate is fixedly connected to the inner wall of the support frame. Two rotating holes are opened on the inner wall of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a positioning mechanism, the positioning fixture can internally support and fix the ring-shaped product, which can ensure the stability of the ring-shaped product and prevent the ring-shaped product from shaking during processing, thus affecting the processing quality. In addition, the internal support method can prevent the ring-shaped product from being partially processed due to the outer wall blocking it. Furthermore, the multi-station fixing can fix multiple ring-shaped products at the same time, thereby processing multiple products and improving the processing efficiency of ring-shaped products.

[0016] 2. By setting a drive mechanism, the positioning fixture can adjust the processing angle of the ring product during use, thereby achieving comprehensive processing of the ring product. Furthermore, by rotating the ring product, the outer surface of the ring product can be quickly ground and polished, ensuring the efficiency of ring product processing. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a ring-shaped product internal support positioning fixture, including a support frame 1, a driving mechanism 3 and a positioning mechanism 2 on the top of the support frame 1; the positioning mechanism 2 includes two cross plates 201, both of which are rotatably connected to the top of the support frame 1. A threaded sleeve 202 is provided on the top of the cross plate 201, and a threaded rod 203 is threadedly connected to the inner wall of the threaded sleeve 202. A pressure plate 204 is provided on the outer wall of the threaded rod 203, and a lifting sleeve 205 is connected to the bottom of the pressure plate 204. The inner wall of the lifting sleeve 205 is slidably connected to the outer wall of the threaded sleeve 202. Multiple first unfolding plates 206 are fixedly connected at equal intervals to the outer wall of the lifting sleeve 205. The first unfolding plates 206 are hinged to the same second unfolding plate 207 through multiple hinge frames 208. An arc-shaped clamping plate 209 is fixedly connected to one side of the second unfolding plate 207.

[0024] The cross plate 201 has multiple grooves 4 inside. The inner wall of the groove 4 is slidably connected to a slider 5. The top of the slider 5 is connected to the bottom of the arc-shaped clamping plate 209. The inner wall of the groove 4 and the outer wall of the slider 5 are both polished. By setting the groove 4 and the slider 5, the arc-shaped clamping plate 209 can play a limiting and guiding role during its movement, so that the arc-shaped clamping plate 209 can expand outward to support and fix the inner wall of the ring product. Polishing the groove 4 and the slider 5 can reduce the friction between the groove 4 and the slider 5, and prevent the slider 5 from getting stuck or jammed during the sliding process.

[0025] The outer wall of the threaded rod 203 is rotatably connected to the inner wall of the pressure plate 204. A knob 6 is fixedly connected to the top of the threaded rod 203. By setting the knob 6, the threaded rod 203 can be rotated, so that the threaded rod 203 drives the lifting sleeve 205 to move through the pressure plate 204.

[0026] The drive mechanism 3 includes a motor 301, which is fixedly connected to the bottom of the inner wall of the support frame 1. The output end of the motor 301 is driven by a first synchronous pulley 302. The first synchronous pulley 302 is driven by a synchronous belt 304 and a second synchronous pulley 303. The inner walls of the first synchronous pulley 302 and the inner walls of the second synchronous pulley 303 are driven by rotating rods 305. The outer walls of the two rotating rods 305 are rotatably connected to the inner walls of the two cross plates 201 respectively. By setting the drive mechanism 3, the positioning fixture can adjust the processing angle of the ring product during use, thereby achieving comprehensive processing of the ring product. Furthermore, by rotating the ring product, the outer surface of the ring product can be quickly polished, ensuring the efficiency of the ring product processing.

[0027] The bottom of the cross plate 201 is fixedly connected to a first bearing seat 7, which contains a bearing. The first bearing seat 7 is rotatably connected to the rotating rod 305 through the bearing. By setting the bearing and the first bearing seat 7, the rotating rod 305 can be supported during rotation, thereby ensuring the stability of the rotation of the rotating rod 305 and reducing the friction generated when the rotating rod 305 rotates, thus reducing the energy loss during rotation.

[0028] A second bearing seat 8 is fixedly connected to the bottom of the inner wall of the support frame 1. The second bearing seat 8 is rotatably connected to the stabilizer rod 9 through a bearing. The outer wall of the stabilizer rod 9 is connected to the inner wall of the second synchronous wheel 303. A support plate 10 is fixedly connected to the inner wall of the support frame 1. The inner wall of the support plate 10 has two rotating holes. The support plate 10 is rotatably connected to two rotating rods 305 through the rotating holes. By setting the second bearing seat 8 and the stabilizer rod 9, the second synchronous wheel 303 can be supported, thereby ensuring the stability of the rotation of the second synchronous wheel 303. The support plate 10 can also provide auxiliary support for the two rotating rods 305, so that the rotating rods 305 can drive the cross plate 201 to rotate stably, thus ensuring the stability of the rotation of the cross plate 201.

[0029] Working principle:

[0030] In use, rotating knob 6 causes the threaded rod 203 to rotate. Since the threaded rod 203 is threadedly connected to the threaded sleeve 202, it moves downwards along the sleeve. This downward movement of the threaded rod 203 presses against the pressure plate 204, causing the pressure plate 204 to move downwards as well. The downward movement of the pressure plate 204 then moves the lifting sleeve 205 downwards. As the lifting sleeve 205 moves downwards, it presses against the hinge frame 208, which in turn presses against the arc-shaped clamping plate 209. Since the arc-shaped clamping plate 209 is connected to the slider 5 and guided by the slider 5 and the slide groove 4, the pressure on the arc-shaped clamping plate 209 causes the slider 5 to move outwards along the slide groove 4, thereby... The arc-shaped clamping plate 209 moves outward. Through multiple outward-moving arc-shaped clamping plates 209, the inner wall of the annular product can be internally supported and fixed. When it is necessary to adjust the processing angle of the annular product, the motor 301 is started. The motor 301 drives the first synchronous wheel 302 to rotate. The first synchronous wheel 302 drives the second synchronous wheel 303 to rotate through the synchronous belt 304, thereby driving the two rotating rods 305 to rotate. The rotation of the rotating rods 305 drives the cross plate 201 to rotate, thereby driving the positioning mechanism 2 to rotate. Since the positioning mechanism 2 is relatively fixed to the annular product, it drives the annular product to rotate, thereby adjusting the processing angle of the annular product.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
