Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0030] Example 1:

[0031] like Figure 1-7As shown, the cross shaft punching fixture provided by this utility model includes: a worktable 1, on which a support assembly 2, four clamping assemblies 3, and a punching assembly 4 are arranged. The support assembly 2 includes a support base 21, which is fixedly installed on the worktable 1. A detachable and replaceable support member 22 for supporting the middle part of the cross shaft is installed on the support base 21. The top of the support member 22 has a support groove 221 that matches the shape and size of the middle part of the cross shaft. The middle part of the cross shaft is placed in the support groove 221, and the position other than the punching position can fit as close as possible to the inner wall of the support groove 221, providing effective support for the middle part of the cross shaft. When punching cross shafts of different specifications, the support member 22 can be replaced with one corresponding to the cross shaft. 2. To effectively support different models of cross shafts, the clamping assembly 3 includes a screw 31 with one end rotatably connected to the support base 21, a clamping block 32 threaded onto the screw 31, the bottom of the clamping block 32 slidably connected to the worktable 1, and a V-shaped groove on the top of the clamping block 32. The other end of the screw 31 is rotatably mounted with a support block 33, and the bottom end of the support block 33 is fixedly connected to the worktable 1. In use, the middle part of the cross shaft is placed in the support groove 221 to support and position the cross shaft, and the end of the cross shaft is placed into the groove on the top of the clamping block 32. Then, the screw 31 is rotated to move the clamping block 32 closer to the support base 21, thereby clamping and fixing the end of the cross shaft. Then, the punching assembly 4 is used to punch holes in the cross shaft. When punching cross shafts of different specifications, especially those with inconsistent central shapes and specifications, the original support 22 can be removed and replaced with a support 22 that matches the specifications of the cross shaft to be punched. This allows for effective support of the central part of the cross shaft when punching cross shafts of different thicknesses, preventing bending and deformation during punching, facilitating subsequent processing, and effectively improving product quality.

[0032] By setting up a support assembly 2 including a support base 21 and a support member 22, and opening a support groove 221 on the support member 22 that matches the cross shaft, the middle part of the cross shaft can be effectively supported when punching, making it less prone to bending and deformation, which is beneficial to improving product quality. Furthermore, by replacing the support member 22, it is easy to adapt to different models of cross shafts for punching.

[0033] Example 2:

[0034] like Figure 3As shown, a mounting groove and four mounting holes 211 communicating with the mounting groove are opened on the top of the support base 21. Four connecting ears 214 are installed around the bottom of the support base 21. During installation, screws are used to pass through the connecting ears 214 to fix the support base 21 on the workbench 1. One end of the screw 31 passes through the mounting hole 211 and extends into the mounting groove. The screw 31 and the mounting hole 211 are rotatably connected by a bearing.

[0035] The mounting hole 211 and connecting lug 214 facilitate the installation of the support base 21 and the screw 31.

[0036] Example 3:

[0037] like Figure 3-5 As shown, in this embodiment, a positioning groove 222 is provided at the bottom of the support member 22, and a positioning post 223 is installed in the positioning groove 222. A positioning pin 224 is fixedly installed on one side of the positioning post 223, and a guide groove 213 is provided on one side of the mounting groove. The positioning post 223 is adapted to the mounting groove, and the positioning groove 222 is adapted to the support base 21. When the support member 22 and the support base 21 are connected, the positioning post 223 is inserted into the mounting groove, and the positioning pin 224 is inserted into the guide groove 213. The top of the support base 21 is inserted into the positioning groove 222. Through the above measures, the support member 22 and the support base 21 are oriented and inserted into each other, which improves the installation accuracy between the two. The support member 22 is also easy to disassemble and replace. It is worth noting that screws can be installed on the side of the support member 22, and the two can be fixed by pressing the support base 21 with screws.

[0038] By setting the positioning groove 222, positioning column 223, positioning pin 224 and guide groove 213, the installation accuracy of the support 22 and the support base 21 can be effectively improved, and the support 22 can be easily disassembled and replaced.

[0039] Example 4:

[0040] like Figure 6-7 As shown, a drive motor 34 is installed at the bottom of the workbench 1, an active bevel gear 212 is rotatably installed in the mounting slot of the support base 21, and a driven bevel gear 35 is fixedly installed at the end of the screw 31. The driven bevel gear 35 meshes with the active bevel gear 212, and the output shaft of the drive motor 34 is connected to the active bevel gear 212. It is worth noting that the drive motor 34 can also be replaced by a motor or other power source. When in use, the drive motor 34 starts (forward or reverse), causing the active bevel gear 212 to rotate, which in turn drives the driven bevel gear 35 to rotate. Thus, the screw 31 is driven to rotate by the driven bevel gear 35, so that the four clamping blocks 32 can move away from or close to the support base 21 at the same time.

[0041] By setting the driving bevel gear 212 and the driven bevel gear 35, the four clamping blocks 32 can be moved simultaneously by the drive motor 34.

[0042] Example 5:

[0043] like Figure 7 As shown, the punching assembly 4 includes a cross groove 41, which is aligned with the screw 31 below. The cross groove 41 is fixedly connected to the worktable 1, and the center of the cross groove 41 is aligned with the center of the support base 21. A slider 42 is installed in the cross groove 41, and a hydraulic cylinder 43 is installed below the slider 42. The hydraulic cylinder 43 is connected to the slider 42 by four screws 45, which fix the slider 42 in the cross groove 41. A punching head 44 is installed at the bottom of the hydraulic cylinder 43. In use, the hydraulic cylinder 43 is activated, causing the punching head 44 to descend and perform punching operations on the cross shaft below. It is worth noting that the screws 45 can be turned to move the slider 42 along the cross groove 41, and then the screws 45 can be tightened to adjust the punching position of the punching head 44 aligned with the cross shaft below. Therefore, the punching position on the cross shaft can be adjusted, making it more flexible to use.

[0044] By setting a punching assembly 4 including a cross groove 41, a slider 42, a hydraulic cylinder 43 and a punching head 44, the cross shaft can be punched and the punching position can be adjusted.

[0045] Working principle: In use, the middle part of the cross shaft is placed in the support groove 221 for support and positioning. The end of the cross shaft is placed into the slot at the top of the clamping block 32. Then, the screw 31 is rotated to move the clamping block 32 closer to the support base 21, thereby clamping and fixing the end of the cross shaft. Then, the punching assembly 4 is used to punch the cross shaft. When it is necessary to punch cross shafts of different specifications, especially those with inconsistent central shapes and specifications, the original support 22 can be removed and replaced with a support 22 that matches the specifications of the cross shaft to be punched. This allows cross shafts of different thicknesses to be punched effectively supported in the middle by replacing the support 22 with one that matches the cross shaft, thus facilitating the punching of cross shafts of different models.
