Description

Technical Field

[0001] This utility model relates to the technical field of wedge grooving tooling equipment, and in particular to a conical elastic wedge grooving tooling device. Background Technology

[0002] A wedge grooving fixture is a tool or device specifically designed for grooving wedges. Its main function is to fix the wedge in the processing position through a precise clamping and positioning device, and then cut, carve, or perform other processing operations on it.

[0003] Utility model patent CN214423027U discloses a self-compacting corner fixture for fixing wedges in high-speed rail and subway systems. The key technical features are: a corner template, insert plates, and wedges; both the corner template and insert plates are positioned at corresponding corners of the track slab, and both are V-shaped plates with inward-facing openings. The V-shaped angle formed by the corner template and insert plates matches the corresponding corner on the track slab. Each end of the corner template has a limiting block that connects and limits the edge sealing template and end mold, respectively. The connection between the limiting block and the corner template forms an inward-facing groove. The insert plates are placed within the groove, with both ends abutting against the side walls of the groove. The wedges are positioned between the insert plates and the corner template, respectively, and are interference-fitted with both. This utility model provides sufficient space between the corner template and the track slab for insert plate insertion, facilitating operation by construction personnel and ensuring the sealing between the insert plates and the track slab is not affected.

[0004] Regarding the aforementioned issues, the following technical defects exist: In railway construction and maintenance, terminal anchor clamps are one of the important components ensuring the stability of railway lines. Machining the elastic wedges in terminal anchor clamps is a common but challenging task. The quality of the grooving process directly affects the overall performance and reliability of the clamp. Traditional grooving methods have many shortcomings. For example, when grooving manually or with simple tooling, machining accuracy is difficult to guarantee, resulting in large grooving dimensional errors. This leads to low fit accuracy between the wedge and other clamp components, affecting the overall performance and service life of the anchor clamp. Furthermore, manual grooving is slow and inefficient, failing to meet the growing demand for large-scale production. In addition, traditional machining methods are labor-intensive, causing fatigue, which further negatively impacts machining quality and efficiency, increases production costs, and reduces the company's market competitiveness.

[0005] Therefore, it is necessary to provide a new type of conical elastic wedge grooving fixture to solve the above-mentioned technical problems. Utility Model Content

For example, when grooving is done manually or with simple tooling, it is difficult to guarantee processing accuracy, resulting in large grooving dimensional errors. This leads to low matching accuracy between the wedge and other parts of the anchor clamp, affecting the performance and service life of the entire anchor clamp. Moreover, manual grooving is slow and has low production efficiency, which cannot meet the growing demand for large-scale production. In addition, traditional processing methods are labor-intensive and can cause fatigue, which further negatively impacts processing quality and efficiency, increases production costs, and reduces the company's market competitiveness.

[0008] The effects achieved by the aforementioned components are as follows: In railway construction and maintenance, terminal anchor clamps are one of the important components ensuring the stability of railway lines. Machining the elastic wedges in terminal anchor clamps is a common but challenging task. The quality of the grooving process directly affects the overall performance and reliability of the clamp. Traditional grooving methods have many shortcomings. For example, when grooving manually or with simple tooling, the machining accuracy is difficult to guarantee, resulting in large grooving dimensional errors.

Moreover, manual grooving is slow and inefficient, failing to meet the growing demand for large-scale production. Furthermore, traditional machining methods are labor-intensive, causing fatigue, which further negatively impacts machining quality and efficiency, increases production costs, and reduces the company's market competitiveness.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes five positioning spindles 201, all of which are rotatably connected to the inner wall of the support 4. A retaining ring 202 is fixedly connected to one end of the arc surface of each positioning spindle 201. A hexagonal head flange bolt 205 is threaded onto the inner wall of the positioning spindle 201. A first spring 206 is fitted onto the arc surface of the hexagonal head flange bolt 205. Both ends of the first spring 206 are fixedly connected to the hexagonal head flange bolt 205 and the support 4, respectively. A fixing ring 203 is fixedly connected to the arc surface of the positioning spindle 201. Several adjusting holes 204 are provided on the side of the fixing ring 203. A spring pin 208 is slidably connected to the inner wall of one of the adjusting holes 204. The spring pin 208 is slidably connected to the inner wall of the support 4. A second spring pin 208 is fixedly connected to one side of the spring pin 208. Spring 214, the second spring 214, is fixedly connected to a hexagonal socket head cap screw 207 on the side away from the spring nail 208. The hexagonal socket head cap screw 207 is threaded to the inner wall of the support 4. In railway construction and maintenance, the terminal anchor clamp is one of the important components to ensure the stability of the railway line. The machining of the elastic wedge in the terminal anchor clamp is a common but somewhat difficult task. The quality of its grooving directly affects the overall performance and reliability of the clamp. Traditional grooving methods have many shortcomings. For example, when grooving is done manually or with simple tooling, the machining accuracy is difficult to guarantee, and the grooving size error is large, resulting in low matching accuracy between the wedge and other parts of the clamp, affecting the performance and service life of the entire anchor clamp. Manual grooving is slow and inefficient, failing to meet the growing demand for large-scale production. Furthermore, traditional processing methods are labor-intensive, leading to fatigue and negatively impacting processing quality and efficiency, increasing production costs, and reducing the company's market competitiveness. In contrast, adjusting device 2 can precisely control the wedge's position and angle, significantly improving processing accuracy. Compared to traditional methods, this effectively reduces cutting deviations caused by inaccurate positioning, ensuring the processing quality of the terminal anchoring clamp wedge and improving the overall effectiveness and safety of the clamp. An auxiliary block 2 is fixedly connected to the side of the internal hexagonal flat-end set screw 207 away from the second spring 214. 10. The auxiliary block 210 is circular. When rotating the hexagonal set screw 207, the auxiliary block 210 can be used to rotate the hexagonal set screw 207, which can improve the speed and efficiency of rotating the hexagonal set screw 207. Several protrusions 211 are fixedly connected to the arc surface of the auxiliary block 210. The protrusions 211 are evenly distributed on the auxiliary block 210. When rotating the hexagonal set screw 207, the auxiliary block 210 can be used to rotate the hexagonal set screw 207, which can improve the convenience of rotation. A guide block 212 is fixedly connected to the side of the spring pin 208 away from the second spring 214. The guide block 212 is arc-shaped. When the spring pin 208 continues to be connected to the inner wall of the adjusting hole 204,The guide block 212 installed on the spring pin 208 can improve the connection speed between the spring pin 208 and the inner wall of the adjusting hole 204. A telescopic rod 213 is slidably connected to the inner wall of the second spring 214. The two ends of the arc surface of the telescopic rod 213 are fixedly connected to the internal hexagonal set screw 207 and the spring pin 208, respectively. When the second spring 214 moves, the telescopic rod 213 installed inside can limit the movement of the second spring 214, improving the stability of its movement. A cross-shaped through groove 209 is opened on the side of the retaining ring 202 near the fixing ring 203. The cross-shaped through groove 209 facilitates wire cutting, improving the efficiency and stability of wedge processing. The auxiliary block 210 is a titanium alloy block. The titanium alloy auxiliary block 210 has a relatively hard surface and is less prone to deformation even after long-term use, resulting in a longer service life.

[0032] The working principle of the tapered elastic wedge grooving fixture provided by this utility model is as follows: The fixing ring 203 on the positioning mandrel 201 has adjustment holes 204 on its surface. The adjustment holes 204 are distributed along the circumference. The positioning mandrel 201 is vertically arranged on the support 4, with a total of five, so that multiple wedges can be processed at one time, improving processing efficiency. The positioning mandrel 201 has opposing slots that need to be processed, and two opposing slots can be cut at the same time. After processing once, there is no need to re-clamp. Just pull the positioning mandrel 201 out to the retaining ring 202 side and then rotate it until it is locked in the new positioning hole, and you can continue processing. The hexagonal head flange bolt 205 restricts the range of motion. The spring pin 208 and the first spring 206 are fastened to the support 4 by an internal hexagonal flat end set screw 207. The support 4 is connected to the base through the stiffening plate 3, and the stiffening plate 3 can stabilize the connection between the two.
