Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to roller clamping drilling fixture. Background Technology

[0002] Roller brackets are mounted on the frame of a textile machine and connect the components within the spinning machine's condensation zone. The perforated structure in the roller brackets facilitates the fixing and support of these components.

[0003] To ensure the installation accuracy of components within the condensation zone, the machining precision requirements for each hole on the roller bracket are high. When using a general-purpose drilling fixture to machine the holes on the roller bracket, only one hole can be machined at a time, requiring multiple clamping and positioning operations to complete the machining of all holes, resulting in low machining efficiency. Furthermore, multiple clamping and positioning operations are prone to introducing errors, affecting the positional accuracy of the holes.

[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 clamping and punching fixture to improve the processing efficiency and accuracy of holes on roller brackets.

[0006] The technical solution of this utility model is as follows: A roller clamping and punching fixture is installed on a roller bracket to assist in machining the hole to be machined. The fixture includes a left and right clamping plates positioned laterally opposite each other on the roller bracket, a first positioning roller positioned between the left and right clamping plates, an upper and lower pressure block positioned vertically opposite each other on the roller bracket, and a clamping rod connecting the upper and lower pressure blocks. A guide hole is provided on the right clamping plate to align with the hole to be machined. The first positioning roller engages with the front roller groove of the roller bracket. The left and right clamping plates and the first positioning roller are positioned between the upper pressure block and the roller bracket.

[0007] A further technical solution involves aligning positioning holes on the left and right clamping plates. These positioning holes are offset from the roller bracket.

[0008] A further technical solution involves providing a second positioning roller between the left and right clamping plates. This second positioning roller is positioned between the roller support and the upper pressure block.

[0009] A further technical solution involves setting the first and second positioning rollers on the right clamping plate. Fasteners are installed on the left clamping plate, connecting the left clamping plate and the first positioning roller. The fasteners also connect the left clamping plate and the second positioning roller.

[0010] A further technical solution is that the clamping rod can be a bolt. A pad is placed between the head of the clamping rod and the left clamping plate.

[0011] A further technical solution is to install a bushing inside the guide hole.

[0012] A further technical solution is that the end of the bushing away from the left clamp extends out of the guide hole.

[0013] A further technical solution involves providing an upper limit protrusion on the side of the upper pressure block closest to the roller bracket. This upper limit protrusion engages between the left and right clamping plates.

[0014] A further technical solution involves providing a lower limiting groove on the side of the lower pressure block near the roller bracket. The roller bracket then engages with the lower limiting groove.

[0015] A further technical solution is to open a waist-shaped hole on the upper pressure block, and to pass the clamping rod through the waist-shaped hole through the upper pressure block.

[0016] The beneficial technical effects of this utility model are as follows: (1) The roller clamping and punching fixture of this utility model has a left clamping plate and a right clamping plate arranged horizontally, and an upper pressure block and a lower pressure block arranged vertically, so as to clamp and fix the roller clamping and punching fixture on the roller bracket in a circumferential manner, ensuring the stability of the roller clamping and punching fixture. In addition, a first positioning roller is also provided. The first positioning roller is inserted into the front roller groove to position the relative position of the right clamping plate and the roller bracket. The front roller groove is an arc-shaped groove. After the first positioning roller is inserted into the front roller groove, the arc surface will guide the first positioning roller to shift to the center of the front roller groove, ensuring the coaxiality of the front roller groove and the first positioning roller, and ensuring the positional accuracy of the guide hole. And corresponding to the number of holes to be processed, a corresponding number of guide holes can be set on the right clamping plate, so that all the holes to be processed can be processed in one clamping. The number of clamping times is reduced, improving the processing efficiency of the roller bracket, and also avoiding the error caused by multiple clamping that affects the processing accuracy of the holes to be processed.

[0017] (2) Furthermore, positioning holes are provided on the left and right clamping plates respectively. The positioning pin connects the left and right clamping plates along the positioning holes, which can limit the relative position of the left and right clamping plates and facilitate the assembly of the roller clamping and punching fixture.

[0018] (3) Furthermore, a second positioning roller is also provided. The second positioning roller and the first positioning roller cooperate to position the guide hole and the roller bracket at multiple points, thereby improving the positioning accuracy of the guide hole and thus improving the processing accuracy of the hole to be processed.

[0024] Figure 1 A three-dimensional structural schematic diagram of a roller clamping and punching fixture according to an embodiment of the present disclosure is shown, which is installed behind a roller bracket. Figure 2 A three-dimensional structural schematic diagram of a roller clamping and punching fixture according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2A roller clamping and punching fixture is installed on the roller bracket 8 to assist in machining the hole 82 to be machined. The roller clamping and punching fixture includes a left clamping plate 1 and a right clamping plate 2 arranged on opposite sides of the roller bracket 8, a first positioning roller 3 positioned between the left clamping plate 1 and the right clamping plate 2, an upper pressure block 5 and a lower pressure block 6 arranged on opposite sides of the roller bracket 8, and a clamping rod 7 connecting the upper pressure block 5 and the lower pressure block 6. The left clamping plate 1, the right clamping plate 2, and the first positioning roller 3 are clamped between the upper pressure block 5 and the roller bracket 8. The horizontally arranged left clamping plate 1 and the right clamping plate 2 cooperate with the vertically arranged upper pressure block 5 and lower pressure block 6 to circumferentially clamp and fix the roller clamping and punching fixture on the roller bracket 8, ensuring the stability of the roller clamping and punching fixture. A guide hole 21 is provided on the right clamping plate 2 to align with the hole 82 to be machined. The first positioning roller 3 engages in the front roller groove 81 of the roller bracket 8 to position the relative position of the right clamping plate 2 and the roller bracket 8.

[0025] The front roller groove 81 is an arc-shaped groove. After the first positioning roller 3 is engaged in the front roller groove 81, the arc-shaped surface guides the first positioning roller 3 to shift away from the center of the front roller groove 81, ensuring the coaxiality of the front roller groove 81 and the first positioning roller 3, and ensuring the positional accuracy of the guide hole 21. Furthermore, corresponding to the number of holes 82 to be processed, a corresponding number of guide holes 21 can be set on the right clamping plate 2, allowing all holes 82 to be processed to be processed in a single clamping operation. This reduces the number of clamping operations, improves the processing efficiency of the roller bracket 8, and avoids the impact of errors caused by multiple clamping operations on the processing accuracy of the holes 82.

[0026] Preferably, positioning holes 11 are aligned on the left clamping plate 1 and the right clamping plate 2. Positioning pins (not shown in the figure) connect both the left clamping plate 1 and the right clamping plate 2 along the positioning holes 11, which limits the relative position of the left clamping plate 1 and the right clamping plate 2, facilitating the assembly of the roller clamping and punching fixture. The positioning holes 11 are offset from the roller bracket 8 to avoid interference between the positioning pins and the roller bracket 8.

[0027] Please refer to Figure 1 and Figure 2 A second positioning roller 4 is also provided between the left clamping plate 1 and the right clamping plate 2. The second positioning roller 4 is located between the roller bracket 8 and the upper pressure block 5, and the positioning roller abuts against the roller bracket 8. The second positioning roller 4 and the first positioning roller 3 cooperate to position the guide hole 21 and the roller bracket 8 at multiple points, thereby improving the positioning accuracy of the guide hole 21 and thus improving the machining accuracy of the hole 82 to be processed.

[0028] Preferably, the first positioning roller 3 and the second positioning roller 4 are disposed on the right clamping plate 2. A fastener 12 is disposed on the left clamping plate 1. The fastener 12 connects the left clamping plate 1 and the first positioning roller 3. The fastener 12 also connects the left clamping plate 1 and the second positioning roller 4. In some embodiments, the fastener 12 can be a bolt. Correspondingly, the first positioning roller 3 and the second positioning roller 4 have threaded holes (not shown in the figure) for threaded connection of the fastener 12. The bolt shank extends into the threaded hole, and the bolt head abuts against the left clamping plate 1 for positioning.

[0029] More preferably, when the clamping rod 7 is a bolt, a pad 13 is provided between the head of the clamping rod 7 and the left clamping plate 1. The pad 13 disperses the pressure applied to the left clamping plate 1 by the clamping rod 7 and also prevents the clamping rod 7 from directly contacting the surface of the left clamping plate 1, so as to protect the surface of the left clamping plate 1 and prevent crushing, scratching and abrasion of the left clamping plate 1.

[0030] Please refer to Figure 1 and Figure 2 A bushing 211 is installed inside the guide hole 21. The bushing 211 is made of high-strength material to protect the guide hole 21 and prevent direct wear of the guide hole 21 when machining the hole to be machined 82 along the guide hole 21, thus extending the service life of the right clamping plate 2. Subsequent maintenance only requires replacing the bushing 211, without the need to repair the right clamping plate 2, reducing the maintenance cost of the roller clamping and drilling tool.

[0031] Preferably, the end of the bushing 211 furthest from the left clamping plate 1 extends out of the guide hole 21. The length of the bushing 211 is longer than the length of the guide hole 21, which extends the effective guiding section of the guide hole 21, increases the contact length between it and the tool, and ensures the stability of the tool and the machining accuracy of the hole 82 to be machined.

[0032] Please refer to Figure 1 and Figure 2 An upper limit protrusion 51 is provided on the side of the upper pressure block 5 near the roller bracket 8. The upper limit protrusion 51 is engaged between the left clamping plate 1 and the right clamping plate 2, which restricts the relative position between the upper pressure block 5 and the left clamping plate 1 and the right clamping plate 2, and prevents the upper pressure block 5 from sliding relative to the left clamping plate 1 and the right clamping plate 2, thus affecting the stability of the roller clamping and drilling fixture when it is fixed on the roller bracket 8.

[0033] Preferably, a lower limiting groove 61 is provided on the side of the lower pressure block 6 near the roller bracket 8. The roller bracket 8 is inserted into the lower limiting groove 61, which restricts the relative position of the roller bracket 8 and the lower pressure block 6, and prevents the lower pressure block 6 from sliding relative to the roller bracket 8, thus affecting the stability of the roller clamping and punching fixture.

[0034] More preferably, an oblong hole 52 is provided on the upper pressure block 5, and the clamping rod 7 passes through the upper pressure block 5 along the oblong hole 52. The clamping rod 7 can move slightly along the long axis of the oblong hole 52, which makes it easy for the clamping rod 7 to align with the screw hole on the lower pressure block 6, and facilitates the installation of the roller clamping and drilling operation on the roller bracket 8.

[0035] The specific workflow of this utility model is as follows: Move the right clamping plate 2 to the installation position of the roller bracket 8. The first positioning roller 3 engages in the front roller groove 81, and the second positioning roller 4 abuts against the roller bracket 8. Then move the left clamping plate 1. The left clamping plate 1 and the right clamping plate 2 are positioned on opposite sides of the roller bracket 8, and the fastener 12 connects the left clamping plate 1 and the right clamping plate 2. The left clamping plate 1 and the right clamping plate 2 clamp the roller bracket 8. Then move the upper pressure block 5. The upper limit protrusion 51 extends between the left clamping plate 1 and the right clamping plate 2. Then move the lower pressure block 6. The lower pressure block 6 and the upper pressure block 5 are positioned on opposite sides of the roller bracket 8. The roller bracket 8 extends into the lower limit groove 61. The clamping rod 7 connects the upper pressure block 5 and the lower pressure block 6, driving the upper pressure block 5 and the lower pressure block 6 to clamp the roller bracket 8, the first positioning roller 3, and the second positioning roller 4. After the roller clamping and punching fixture is installed, the guide hole 21 is aligned with the machining position of the hole 82 to be machined, and the hole 82 to be machined can be machined along the guide hole 21.

[0036] 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.

[0037] 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.
