Description

Technical Field

[0001] This utility model relates to the field of ring-shaped component processing technology, specifically a positioning fixture for anti-deformation conical holes in ring-shaped components. Background Technology

[0002] Ring-shaped parts are circular parts with holes. They play a vital role in mechanical devices, providing stability, sealing, and connectivity. Ring-shaped parts can provide stable connections and support, ensuring the normal operation of mechanical devices. Elastic rings and locking rings are often used to connect parts, ensuring their stability and reliability. Ring-shaped parts can withstand high pressure and vibration, maintaining the connection of parts and preventing loosening.

[0003] Existing positioning fixtures for machining ring-shaped parts still have certain shortcomings in use:

[0004] During the positioning of the ring-shaped part, due to the lack of shock absorption or protective structure, if the applied clamping or pressing force is too strong, the ring-shaped part is prone to deformation, thereby reducing the processing quality.

[0005] Due to the differences in the size of the ring parts, smaller ring parts are prone to stability problems during the fixing process, which may interfere with the processing operation. In addition, it is less convenient to protect the surface of the ring parts when positioning and clamping them. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning fixture for anti-deformation conical holes of annular parts, in order to solve the problems mentioned in the background art. In the process of positioning annular parts, due to the lack of shock absorption or protective structure, if the applied clamping force or pressing force is too strong, the annular parts are prone to deformation, thereby reducing the processing quality. Due to the difference in size of annular parts, smaller annular parts are prone to stability problems during the fixing process, which may interfere with the processing operation. In addition, when positioning and clamping annular parts, protecting the surface of the annular parts becomes less convenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A positioning fixture for anti-deformation conical holes of annular parts includes a processing plate, on the top of which a protective component and an auxiliary component are respectively provided, and the protective component and the auxiliary component are positioned opposite each other;

[0009] The protective assembly includes a fixed rod fixedly connected to the top of the processing plate, an adjusting cylinder slidably connected to the outer surface of the fixed rod, a first fixed seat fixedly connected to the side of the adjusting cylinder, a movable block provided on the top of the processing plate, a guide plate provided on the side of the movable block, a shock-absorbing spring elastically connected between the guide plate and the movable block, a damping rod provided inside the shock-absorbing spring, a second fixed seat provided on the side of the guide plate, and a hinge rod hinged between the first fixed seat and the second fixed seat.

[0010] As a preferred embodiment of this utility model, the auxiliary component includes a positioning block fixedly connected to the top of the processing plate, an adjustment knob provided on the side of the positioning block, an adjustment rod fixedly connected to the side of the adjustment knob, the adjustment rod passing through the positioning block and threadedly connected to the positioning block, and a limit plate fixedly connected to the end of the adjustment rod.

[0011] As a preferred embodiment of this utility model, the top of the processing plate is provided with a sliding groove, and the bottom of the movable block is fixedly connected with a moving plate, the moving plate extending into the sliding groove and slidably connected to the sliding groove.

[0012] As a preferred embodiment of this utility model, the movable block and the positioning block are positioned opposite each other, and protective pads are fixedly connected to the sides of the movable block and the positioning block respectively.

[0013] As a preferred embodiment of this utility model, the outer surface of the fixing rod is threaded with two limiting rings, which are located at the top and bottom of the adjusting cylinder, respectively.

[0014] As a preferred embodiment of this utility model, the top of the fixing rod is threaded with a limiting piece, and the outer surface of the fixing rod is coated with an anti-corrosion solution.

[0015] As a preferred embodiment of this utility model, the bottom of the processing plate is provided with four positioning holes, which are respectively located at the bottom corners of the processing plate.

[0016] As a preferred embodiment of this utility model, the movable block and the positioning block are the same size, and the outer surfaces of the movable block and the positioning block are coated with an anti-corrosion solution.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by using a combination of a fixed rod, an adjusting cylinder, a first fixed seat, a hinge rod, a second fixed seat, a guide plate, a shock-absorbing spring, and a sliding block, effective protection and stable clamping of the annular part during the positioning process of the conical hole are achieved. The adjusting cylinder cooperates with the fixed rod, and by adjusting their relative positions, it can adapt to annular parts of different sizes, improving the versatility and practicality of the tooling. A hinge rod is hinged between the first fixed seat and the second fixed seat, allowing the hinge rod to swing within a certain range to adapt to different shapes and sizes of the annular part. A shock-absorbing spring is elastically connected between the guide plate and the sliding block, thereby achieving shock-absorbing clamping of the annular part. The movable block is slidably connected to the sliding groove through a moving plate, improving the stability of the movable block when it moves.

[0019] 2. In this utility model, by setting a positioning block, adjusting knob, adjusting rod, limiting plate and protective plate in combination, the positioning block and the movable block are positioned opposite each other, which facilitates the positioning of the ring part. When processing a smaller ring part, the adjusting rod can be rotated by adjusting knob, so that the limiting plate limits the ring part, which improves the stability during processing. Since protective pads are set on the sides of the movable block and the positioning block respectively, the surface of the ring part can be protected when positioning it. Attached Figure Description

[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A positioning fixture for anti-deformation conical holes of annular parts includes a processing plate 1. A protective component 2 and an auxiliary component 3 are respectively provided on the top of the processing plate 1, with the protective component 2 and auxiliary component 3 positioned opposite each other. The protective component 2 includes a fixed rod 5 fixedly connected to the top of the processing plate 1. An adjusting cylinder 203 is slidably connected to the outer surface of the fixed rod 5. A first fixed seat 204 is fixedly connected to the side of the adjusting cylinder 203. A movable block 201 is provided on the top of the processing plate 1. A guide plate 207 is provided on the side of the movable block 201. A shock-absorbing spring 208 is elastically connected between the guide plate 207 and the movable block 201. A damping rod is provided inside the shock-absorbing spring 208. A second fixed seat 205 is provided on the side of the guide plate 207. A hinge rod 206 is hinged between the first fixed seat 204 and the second fixed seat 205. A sliding groove 7 is opened on the top of the processing plate 1. A moving plate 209 is fixedly connected to the bottom of the movable block 201. The moving plate 209 extends into the sliding groove 7 and is slidably connected to the sliding groove 7.

[0028] The adjusting cylinder 203 causes the hinge rod 206 to move the guide plate 207 and the moving plate 209, thereby achieving precise positioning of the tapered hole of the annular part. During the positioning process, the shock-absorbing spring 208 can effectively absorb the vibration generated during the processing and protect the annular part from damage.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the auxiliary component 3 includes a positioning block 301 fixedly connected to the top of the processing plate 1. An adjustment knob 302 is provided on the side of the positioning block 301. An adjustment rod 303 is fixedly connected to the side of the adjustment knob 302. The adjustment rod 303 passes through the positioning block 301 and is threadedly connected to the positioning block 301. A limit plate 304 is fixedly connected to the end of the adjustment rod 303. The movable block 201 and the positioning block 301 are positioned opposite each other. Protective pads 8 are fixedly connected to the sides of the movable block 201 and the positioning block 301 respectively. Two limit rings 202 are threadedly connected to the outer surface of the fixed rod 5 respectively. The two limit rings 202 are located at the top and bottom of the adjustment cylinder 203 respectively. A limit piece 6 is threadedly connected to the top of the fixed rod 5. The outer surface of the fixed rod 5 is coated with an anti-corrosion solution. Four positioning holes 4 are opened at the bottom of the processing plate 1. The four positioning holes 4 are respectively located at the bottom corner of the processing plate 1. The movable block 201 and the positioning block 301 are the same size. The outer surfaces of the movable block 201 and the positioning block 301 are coated with an anti-corrosion solution.

[0030] The positioning effect of the annular component is further enhanced by rotating the adjustment knob 302 to move the adjustment rod 303 and the limiting plate 304.

[0031] The working process of this utility model is as follows: When using the annular part anti-deformation conical hole positioning fixture designed in this solution, first check whether the fixture is working properly. After confirming that there are no problems, place the annular part to be processed on the processing plate 1. Then, use the movable block 201 in the protective component 2 to further limit the annular part, ensuring that it will not shift or deform during processing. At this time, the adjusting cylinder 203 and the hinge rod 206 work together. The adjusting cylinder 203 causes the hinge rod 206 to drive the guide plate 207 and the moving plate 209 to move, thereby... To achieve precise positioning of the conical hole of the annular part, the shock-absorbing spring 208 can effectively absorb the vibration generated during the processing and protect the annular part from damage. Next, using the positioning block 301 and the adjusting knob 302 in the auxiliary component 3, the adjusting rod 303 and the limiting plate 304 are moved by rotating the adjusting knob 302 to further strengthen the positioning effect of the annular part. At the same time, protective pads 8 are respectively provided on the sides of the movable block 201 and the positioning block 301, so that the surface of the annular part can be protected when positioning it.
