Description

Technical Field

[0001] This utility model relates to the technical field of spinning equipment production equipment, and in particular to roller punching fixtures. Background Technology

[0002] Several holes need to be made on the roller bracket to accommodate or support components, facilitating the installation of components in the condensation zone of the spinning machine.

[0003] The machining precision of the holes in roller brackets is much higher than that of ordinary mechanical parts to ensure the positional accuracy of components within the cohesive zone. General-purpose drilling fixtures are insufficient to meet the required machining precision. Furthermore, roller brackets have multiple holes, while conventional fixtures can only machine one hole at a time. Multiple clamping and positioning operations are required to complete the machining of all holes, affecting the positional accuracy between holes and resulting in low machining efficiency.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a roller punching fixture to improve the machining accuracy and efficiency of holes on roller brackets.

[0006] The technical solution of this utility model is as follows: A roller punching fixture is provided, mounted on a roller support to assist in machining holes. The fixture includes a support plate, an upper pressure block, a lower pressure block, a first positioning roller, and a clamping rod. Positioning holes are formed on the support plate to align with the holes to be machined. The upper and lower pressure blocks are positioned on opposite sides of the roller support. The first positioning roller is mounted on the support plate between the upper pressure block and the roller support, and is engaged in the front roller groove of the roller support. The clamping rod simultaneously connects to and clamps the upper and lower pressure blocks in opposite directions.

[0007] A further technical solution involves providing a positioning protrusion along the radial direction of the first positioning roller, extending radially away from the end of the first positioning roller away from the support plate. The positioning protrusion and the support plate are located on opposite sides of the roller bracket.

[0024] Figure 1 A three-dimensional structural schematic diagram of a roller punching fixture according to an embodiment of the present disclosure is shown in the front view. Figure 2 A front view of a roller punching fixture according to an embodiment of the present disclosure, mounted on a roller bracket, is shown. Figure 3 A three-dimensional structural diagram of a roller punching fixture according to an embodiment of this disclosure is shown in the rear view. Please refer to... Figure 1 , Figure 2 and Figure 3A roller punching fixture is provided on a roller bracket 7 to assist in the processing of holes 72 to be processed. The roller punching fixture includes a support plate 1, an upper pressure block 4, a lower pressure block 5, a first positioning roller 2, and a clamping rod 6. Positioning holes 11 are formed on the support plate 1 to align with the holes 72 to be processed. The upper pressure block 4 and the lower pressure block 5 are positioned on opposite sides of the roller bracket 7. The lower pressure block 5 is close to and corresponds to the surface of the roller bracket 7 to fit against it, ensuring the stability of the fit between the lower pressure block 5 and the roller bracket 7. The first positioning roller 2 is positioned on the support plate 1 between the upper pressure block 4 and the roller bracket 7, and is engaged in the front roller groove 71 of the roller bracket 7. The first positioning roller 2 engages in the front roller groove 71 of the roller bracket 7 to position the relative positions of the support plate 1 and the roller bracket 7 to align the positioning holes 11 and the holes 72 to be processed. All the holes 72 to be machined on the roller bracket 7 can be quickly machined along the positioning hole 11, eliminating the need for repeated clamping and positioning, and improving the machining efficiency and accuracy of the holes 72 to be machined on the roller bracket 7. The clamping rod 6 connects to and clamps the upper pressure block 4 and the lower pressure block 5 in opposite directions.

[0025] In some embodiments, the clamping rod 6 can be a bolt and nut. Specifically, the head of the bolt and the nut are positioned opposite to each other on the upper pressure block 4 and the lower pressure block 5. Tightening the bolt and nut clamps the upper pressure block 4 and the lower pressure block 5. The upper pressure block 4 and the lower pressure block 5 clamp the roller bracket 7 to fix the support plate 1 on the roller bracket 7, ensuring stability when machining the hole 72 to be machined along the positioning hole 11 and improving the machining accuracy of the hole 72 to be machined.

[0026] Preferably, a bushing 12 is provided inside the positioning hole 11. The bushing 12 is made of high-strength material to protect the positioning hole 11 and prevent direct wear of the positioning hole 11 when machining the hole to be machined 72 along the positioning hole 11, thereby extending the service life of the support plate 1. Subsequent maintenance only requires replacing the bushing 12, without the need to repair the support plate 1, thus reducing the maintenance cost of the roller drilling tool.

[0027] Please refer to Figure 1 and Figure 2 A positioning protrusion 21 is provided radially along the first positioning roller 2, extending radially away from the end of the first positioning roller 2 away from the support plate 1. The positioning protrusion 21 and the support plate 1 are located on opposite sides of the roller bracket 7. The positioning protrusion 21 cooperates with the support plate 1 to clamp the roller bracket 7, ensuring the stability of the roller punching fixture fixed on the roller bracket 7 and improving the processing accuracy of the hole 72 to be processed.

[0028] Preferably, the upper pressure block 4 extends between the positioning protrusion 21 and the support plate 1, restricting the position between the upper pressure block 4 and the first positioning roller 2, preventing the upper pressure block 4 from slipping off the first positioning roller 2, and improving the stability of the upper pressure block 4 clamping the first positioning roller 2 on the roller bracket 7.

[0029] Please refer to Figure 1 and Figure 2 A second positioning roller 3 is also provided on the support plate 1 between the upper pressure block 4 and the roller bracket 7. The second positioning roller 3 contacts the roller bracket 7. The first positioning roller 2 and the second positioning roller 3 cooperate to position the support plate 1 and the roller bracket 7, ensuring that the positioning hole 11 is aligned with the hole 72 to be processed, thus ensuring the processing accuracy of the hole 72.

[0030] Preferably, the first positioning roller 2 and the second positioning roller 3 are detachably connected to the support plate 1 by fasteners 13. In some embodiments, the fasteners 13 can be bolts, and the first positioning roller 2, the second positioning roller 3 and the support plate 1 are respectively provided with screw holes to thread the first positioning roller 2 and the second positioning roller 3 to the support plate 1.

[0031] Please refer to Figure 1 and Figure 2 A pad 41 is provided on the clamping rod 6 on the side of the upper pressure block 4 away from the roller bracket 7. The pad 41 distributes the pressure of the clamping rod 6 to protect the surface of the upper pressure block 4, extend the service life of the upper pressure block 4, and protect the upper pressure block 4. The pad 41 and the upper pressure block 4 can be separately provided or integrated into one structure, and this application does not limit this.

[0032] Preferably, the pad 41 has an inclined surface 411. The pad 41 contacts the upper pressure block 4 through the inclined surface 411, so that the pad 41 is away from the surface of the roller bracket 7 and parallel to the surface of the lower pressure block 5 away from the roller bracket 7. This facilitates the clamping rod 6 to connect and clamp the upper pressure block 4 and the lower pressure block 5.

[0033] The specific workflow of this utility model is as follows: Fastener 13 secures the first positioning roller 2 and the second positioning roller 3 to the support plate 1. The support plate 1 is moved to align the positioning hole 11 and the hole to be processed 72. The upper pressure block 4 and the lower pressure block 5 are moved to the opposite side of the roller bracket 7, with the upper pressure block 4 moving between the positioning protrusion 21 and the support plate 1. The clamping rod 6 connects the upper pressure block 4 and the lower pressure block 5 and drives them to clamp together. The upper pressure block 4 abuts against the first positioning roller 2 and the second positioning roller 3, and the lower pressure block 5 abuts against the roller bracket 7. This continues until the first positioning roller 2 abuts against the roller bracket 7, and the second positioning tube engages with the front roller groove 71, abutting against the roller bracket 7. At this point, the positioning hole aligns with the hole to be processed 72, and the hole to be processed 72 on the roller bracket 7 can be processed along the positioning hole 11.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
