Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, and in particular to a positioning and drilling device for automotive body. Background Technology

[0002] The body shell is the mounting base for all body parts. It usually refers to the rigid spatial structure composed of the main load-bearing elements such as longitudinal and transverse beams and pillars, as well as the sheet metal connected to them. Most bus bodies have a clear frame, while car bodies and truck cabs do not. The body shell usually also includes sound insulation, heat insulation, vibration damping, corrosion protection, sealing and other materials and coatings applied to it.

[0003] In the process of processing automobile bodies, drilling equipment is required to drill holes in the automobile body in order to install other parts. Existing drilling equipment usually uses a rotating screw to drive a fixing plate to press and fix the automobile body when fixing it. However, this fixing method requires rotating the screw multiple times to achieve fixation, which is cumbersome and labor-intensive, affecting the drilling efficiency of the body. Therefore, this utility model provides an automobile body positioning and drilling device. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a positioning and drilling device for automobile housings. It has the following beneficial effects:

[0017] 1. The limiting plate is moved by the fixed rod. When the limiting plate moves on the sliding rod, it squeezes the return spring A. Then, the housing is placed on the surface of the processing table, and the limiting of the fixed rod is released, so that the return spring A pushes the limiting plate to squeeze the two sides of the housing. The rubber pads on the limiting plate can reduce the hard compression on the two sides of the housing and avoid scratches on the two sides of the housing. Then, by rotating the fixing bolt, the compression between the fixing bolt and the threaded tube can limit the fixed rod and the limiting plate, achieving a fast fixing effect and improving work efficiency.

[0018] 2. By rotating the lead screw frame, the position of the support frame on the worktable can be adjusted, allowing drilling operations to be performed on different areas of the housing. After the position is adjusted, the servo motor is turned on, and the output of the servo motor drives the upper jaw plate to rotate. As the upper jaw plate rotates, it pushes the lower jaw plate downwards with the help of the inclined plane. When the lower jaw plate moves downwards, it drives the drill rod to drill holes in the housing, while simultaneously squeezing the return spring B, which causes the limit rods on both sides to perform secondary limit on the housing, improving the stability during drilling. When the upper jaw plate stops pushing the lower jaw plate, the return spring B restores its elastic deformation, thereby returning the lower jaw plate to its original position, achieving the effect of continuous drilling.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a car body positioning and drilling device, including a workbench 1. Two sliding grooves 2 are formed on the surface of the workbench 1, and positioning components 3 are provided on the inner walls of the two sliding grooves 2.

[0028] The positioning component 3 includes a sliding rod 301. Both ends of the sliding rod 301 are fixedly connected to the inner wall of the sliding groove 2. A limiting plate 302 is slidably connected to the surface of the sliding rod 301. A fixing rod 304 is fixedly connected to one side of the limiting plate 302. One end of the fixing rod 304 passes through the side wall of the workbench 1 and is slidably connected to a sliding sleeve 305. The sliding sleeve 305 is fixedly connected to the side wall of the workbench 1. A threaded tube 306 is fixedly connected to one end of the sliding sleeve 305. A fixing bolt 307 is threadedly connected to the surface of the threaded tube 306.

[0029] Specifically, a return spring A303 is sleeved on the surface of the sliding rod 301. One end of the return spring A303 is fixedly connected to the inner wall of the sliding groove 2, and the other end of the return spring A303 abuts against the side wall of the limiting plate 302. The inner wall of the threaded tube 306 is slidably connected to the surface of the fixed rod 304. A rubber pad 308 is provided on the surface of the limiting plate 302.

[0030] Furthermore, when drilling is required on the housing, first pull the fixing rod 304 away from the support frame 403. The fixing rod 304 drives the limiting plate 302 to move. When the limiting plate 302 moves on the sliding rod 301, it squeezes the return spring A303. Then, place the housing on the surface of the processing table and release the limiting of the fixing rod 304. This allows the return spring A303 to push the limiting plate 302 to squeeze the two sides of the housing. The rubber pads 308 on the limiting plate 302 can reduce the hard compression on the two sides of the housing and prevent scratches. Then, by rotating the fixing bolt 307, the compression between the fixing bolt 307 and the threaded tube 306 can limit the fixing rod 304 and the limiting plate 302, achieving a quick fixation effect and improving work efficiency.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 and Figure 3This is the second embodiment of the present invention. Based on the previous embodiment, a drilling assembly 4 is provided on one side of the workbench 1. The drilling assembly 4 includes a movable frame 401, which is fixedly connected to the side wall of the workbench 1. A lead screw frame 402 is rotatably connected to the inner wall of the movable frame 401. A support frame 403 is threadedly connected to the surface of the lead screw frame 402. A servo motor 404 is installed on the top of the support frame 403. The output end of the servo motor 404 passes through the top of the support frame 403 and is fixedly connected to an upper jaw plate 405. A lower jaw plate 406 is meshed with the lower end of the upper jaw plate 405. A drill rod 409 is fixedly connected to the lower surface of the lower jaw plate 406.

[0033] Specifically, a fixing plate 408 is slidably connected to the surface of the drill rod 409. One end of the fixing plate 408 is fixedly connected to the surface of the support frame 403, and a return spring B407 is fixedly connected to the surface of the fixing plate 408. The upper end of the return spring B407 is fixedly connected to the lower surface of the lower jaw disk 406. An extension plate 410 is fixedly connected to the side wall of the lower jaw disk 406. A limit rod 411 is slidably connected to the surface of the extension plate 410. A limit spring 412 is sleeved on the upper end of the limit rod 411. The lower end of the limit spring 412 is fixedly connected to the surface of the extension plate 410. A scale line 413 is provided on the upper surface of the moving frame 401.

[0034] Furthermore, after the housing is fixed, the position of the support frame 403 on the worktable 1 can be adjusted by rotating the lead screw frame 402, thereby enabling drilling operations on different areas of the housing. After the position is adjusted, the servo motor 404 is turned on, and the output end of the servo motor 404 drives the upper jaw plate 405 to rotate. When the upper jaw plate 405 rotates, it pushes the lower jaw plate 406 downward with the help of the inclined surface. When the lower jaw plate 406 moves downward, it drives the drill rod 409 to drill holes in the housing, while simultaneously squeezing the return spring B407, and causing the limit rods 411 on both sides to perform secondary limit on the housing, improving the stability during drilling. When the upper jaw plate 405 stops pushing the lower jaw plate 406, the return spring B407 restores its elastic deformation, thereby returning the lower jaw plate 406 to its original position, achieving the effect of continuous drilling.

[0035] Working principle: When drilling is required on the housing, first pull the fixing rod 304 away from the support frame 403. The fixing rod 304 drives the limiting plate 302 to move. When the limiting plate 302 moves on the sliding rod 301, it squeezes the return spring A303. Then, place the housing on the surface of the processing table, and release the limiting of the fixing rod 304. This allows the return spring A303 to push the limiting plate 302 to squeeze the two sides of the housing. The rubber pads 308 on the limiting plate 302 reduce the hard compression on the sides of the housing, preventing scratches. Then, by rotating the fixing bolt 307, the compression between the fixing bolt 307 and the threaded tube 306 limits the fixing rod 304 and the limiting plate 302, achieving a quick fixing effect and improving work efficiency. After the housing is fixed, the position of the support frame 403 on the worktable 1 can be adjusted by rotating the lead screw frame 402, so that drilling operations can be performed on different areas of the housing. After the position is adjusted, the servo motor 404 is turned on. The output end of the servo motor 404 drives the upper jaw plate 405 to rotate. When the upper jaw plate 405 rotates, it pushes the lower jaw plate 406 downward with the help of the inclined surface. When the lower jaw plate 406 moves downward, it drives the drill rod 409 to drill holes in the housing. At the same time, it squeezes the return spring B407 and causes the limit rods 411 on both sides to limit the housing a second time, improving the stability during drilling. When the upper jaw plate 405 stops pushing the lower jaw plate 406, the return spring B407 restores the elastic deformation, so that the lower jaw plate 406 can return to its original position, achieving the effect of continuous drilling.
