The rear longitudinal beam is usually located at the rear of the vehicle, extends along the longitudinal direction of the vehicle, and connects the vehicle body and the rear axle.

[0003] Since the positions of the mounting holes of the rear longitudinal beam are distributed at different positions on the rear longitudinal beam, when drilling, multi-axis control of the machining center is used to adjust the machining, but the cost is relatively high. When drilling manually, it is necessary to measure and mark points in advance and then use a jig to fix the hand-held drill for drilling. The steps are cumbersome and complex. For this reason, a manual drilling jig for multi-spatial angle of the rear longitudinal beam is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Please refer to Figures 1 to 3, A manual drilling fixture for the multi-spatial angle of the rear longitudinal beam in this embodiment includes a panel formed by welding an adjusting plate 1 and a bending plate 2, and a clamping plate 3 slidably connected to the panel. Among them, both the adjusting plate 1 and the clamping plate 3 are L-shaped, and the vertical ends of the clamping plate 3 and the bending plate 2 are parallel to each other and are used to clamp the automotive rear longitudinal beam.

[0021] In this embodiment, a locking rod 6 is also threadedly installed on the bending plate 2, and an abutting disc 7 is fixedly installed at the end of the locking rod 6. By rotating the locking rod 6, the automotive rear longitudinal beam can be clamped between the bending plate 2 and the clamping plate 3 by the abutting disc 7.

[0022] It should be noted that a chute 11 is formed on the surface of the bending plate 2, and an auxiliary structure for assisting a hand-held drill in drilling is arranged in the chute 11. The auxiliary structure includes a slider 13 slidably installed in the chute 11.

[0023] Preferably, a guiding tube 15 is penetrated through the slider 13. The guiding tube 15 can slide-guide the drill bit part of the drill for determining the drilling position.

[0024] In this embodiment, a limiting strip 12 is fixedly installed on the inner wall of the chute 11, and grooves 14 corresponding to the limiting strip 12 are formed on both side surfaces of the slider 13. The slider 13 is slidably connected to the limiting strip 12 and thus stably slides between the chutes 11.

[0025] In this embodiment, a locking plate 16 extending to the top of the bending plate 2 is fixedly installed at one end of the slider 13, and a threaded tube 17 is fixedly installed on the locking plate 16. A locking pin 18 abutting against the top of the bending plate 2 is threadedly installed in the threaded tube 17 for restricting the position of the slider 13 after sliding.

[0026] It should be noted that scale grooves are formed on the top surface of the bending plate 2 and the side surface of the adjusting plate 1. Through the scale grooves, it is convenient to compare the sliding adjustment distance of the slider 13 and the sliding adjustment distance of the clamping plate 3.

[0027] In this embodiment, two bolts 5 are threadedly installed on the top of the clamping plate 3, and a counterbore 4 for the bolts 5 to slide through is penetrated through one side surface of the adjusting plate 1. The cross-section of the counterbore 4 is T-shaped for enabling the bolts 5 to be slidably restricted in the counterbore 4.

[0028] Since the counterbore 4 is directly penetrated, the clamping plate 3 can be conveniently disassembled for maintenance.

[0029] In this embodiment, a threaded sleeve 10 is rotatably mounted on the top of the clamping plate 3 through a bearing block. An adjustment groove 8 is formed through the top of the adjustment plate 1. A threaded rod 9 is fixedly installed between the two side walls of the adjustment groove 8. The threaded sleeve 10 is threadedly connected to the threaded rod 9. By rotating the threaded sleeve 10, the clamping plate 3 can slide relative to the adjustment plate 1 to adjust the position.

[0030] With such a design, when it is necessary to drill holes at different distances from the edge of the rear longitudinal beam of the vehicle, only the position of the clamping plate 3 needs to be adjusted, so that after the rear longitudinal beam of the vehicle is clamped, the slider 13 corresponds to positions at different distances.

[0031] The working principle of the above embodiment is as follows:

[0032] Place the rear longitudinal beam of the vehicle between the bending plate 2 and the clamping plate 3, rotate the threaded sleeve 10 on the clamping plate 3 to rotate around the threaded rod 9, so that the clamping plate 3 slides relative to the adjustment plate 1 to adjust the position. By comparing the scales on the adjustment plate 1, determine the distance between the slider 13 and the clamping plate 3, that is, determine the distance between the positioning hole of the rear longitudinal beam of the vehicle corresponding to the edge. Rotate the locking rod 6 so that the rear longitudinal beam of the vehicle is clamped between the bending plate 2 and the clamping plate 3, and then slide the slider 13 relative to the sliding groove 11 on the bending plate 2 to adjust the vertical distance between the guide tube 15 on the slider 13 and the rear longitudinal beam of the vehicle. Determine the offset position by comparing the scales on the top of the bending plate 2. Then, by rotating the locking pin 18 at one end of the slider 13, lock the slider 13 inside the sliding groove 11, and the position of the guide tube 15 can be determined, which is convenient for using a hand-held drill for auxiliary drilling.
