Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and specifically discloses a punching and positioning device for automobile parts. Background Art

[0002] Auto parts come in a wide variety of shapes and configurations, and a machining center typically needs to be able to perform turning, milling, grinding, and drilling on these unusually shaped parts. Auto parts also require different mounting holes to connect to the car body, so punching is also necessary, requiring the use of punching equipment.

[0003] In the prior art, punching operations typically involve punching a single hole for a particular type of accessory. After punching the holes for that batch of accessories, the mounting holes for the next batch of accessories are punched. However, when punching mounting holes for accessories within the same batch or between different batches, the locations of each punched hole vary, necessitating adjustments to the accessory mounting positions.

[0004] However, in the prior art, during the process of adjusting the installation position of the accessory, the staff can only determine whether the punch is aligned with the required hole position, or whether the punch needs to be pressed down for calibration, but there is no device that can indicate the required punching position during the accessory position adjustment process.

[0005] Therefore, in view of this, the inventor provides a punching and positioning device for automobile parts to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that when a traditional accessory is adjusting a punching position, there is no device that can indicate the required punching position during the accessory position adjustment process.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides a punching and positioning device for automobile accessories, including a ring, a plurality of slides radially connected to the ring, and a spring provided on the ring and used to squeeze the slide inward. The bottom of the slide is fixed with a light-emitting structure for emitting a light beam and a refractive structure for receiving the light beam and vertically shooting the light beam from the outside to the inside, and the refractive structures are all in contact with the outer wall of the punch.

[0008] Furthermore, it also includes semicircular rings respectively wrapped around both sides of the punch and detachably connected to each other to form a sleeve, and the sleeve is connected to the bottom of the semicircular ring by bolts.

[0009] Furthermore, the light emitting structure includes:

[0010] A fixing seat, fixedly connected to the bottom of the slide plate and having a receiving groove on the inner side;

[0011] The straight line laser light is arranged in the receiving groove and is used for emitting laser light toward the refractive structure.

[0012] Furthermore, the refractive structure includes:

[0013] The refraction box is fixed to the bottom of the slide and connected to the inner side of the fixing seat;

[0014] The light guide box is fixed to the bottom of the refraction box;

[0015] The refraction box and the light guide box are provided with a light guide cavity which is connected to the receiving groove of the fixing seat. The light guide cavity passes through the bottom of the light guide box. A reflector is fixed in the refraction box for refracting the laser beam emitted by the linear laser lamp into a downward vertical laser beam.

[0016] Furthermore, a transparent panel for shielding the light guide cavity is provided at the bottom of the light guide box.

[0017] Furthermore, the refraction box and the light guide box are both opaque.

[0018] The principle and effect of this solution are:

[0019] 1. Compared with the prior art, the present invention guides the light beam emitted by the light-emitting structure through the refractive structures respectively attached to the outer wall of the punch and hits it vertically, hitting the automotive accessories below to form light spots, which are arranged around the punch. When the light spots are evenly distributed circumferentially around the punching position, it indicates that the punch is aligned with the required punching position, serving as a positioning indicator, solving the problem that traditional accessories have no device that can indicate the required punching position during the adjustment process of the accessory position.

[0020] 2. Compared with the prior art, the slide of the utility model is slidably installed on the collar, which can wrap the outer wall of punches of different sizes and can adapt to the positioning operation of punches of various sizes. After the positioning is completed, the collar can be removed to carry out the stamping process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0025] The figure marks in the drawings of the specification include: punch 1, semicircular ring 2, support platform 3, auto parts 4, punching 5, ring 6, fixing seat 7, light guide chamber 8, refraction box 9, straight line laser light 10, reflector 11, transparent panel 12, slide groove 13, guide plate 14, spring 15.

[0026] A punching and positioning device for automobile parts, for example Figure 1 As shown:

[0027] The punch 1 comprises a collar 6, slides mounted around the collar 6 and sliding radially, and springs 15 mounted around the collar 6 to compress the slides inward. Specifically, a semicircular ring 2 is mounted on either side of the punch 1. The two semicircular rings 2 are bolted together to form a sleeve that wraps around and secures the outer wall of the punch 1. The collar 6 is bolted to the bottom of the sleeve.

[0028] like Figure 2 As shown, four sliding grooves 13 are opened on the inner side of the ring 6 in the radial direction. The sliding grooves 13 pass through the inner wall of the ring 6. The inner walls on both sides of the sliding grooves 13 are also provided with guide grooves that do not pass through the inner wall of the ring 6. The slide plate is installed in the sliding grooves 13, and the outer walls on both sides of the slide plate are also integrally formed with guide blocks that are inserted into the guide grooves and can slide along the guide grooves. The spring 15 is installed in the guide groove and is used to press the guide plate 14 inward.

[0029] The bottom of the slide is fixedly mounted, from the outside to the inside, with a light-emitting structure for emitting a light beam and a refractive structure for receiving and projecting the light beam vertically downward. Specifically, the light-emitting structure includes a mounting base 7 fixed to the bottom of the slide with a receiving groove formed inside, and a linear laser light 10 mounted within the receiving groove and emitting laser light.

[0030] The refractive index structure includes a refractive index box 9 fixedly mounted on the bottom of the slide and connected to the inner side of the fixed seat 7, and a light guide box fixedly mounted on the bottom of the refractive index box 9. A light guide chamber 8 is formed within the refractive index box 9 and the light guide box, communicating with the receiving groove of the fixed seat 7. The light guide chamber 8 extends through the bottom of the light guide box. A reflector 11 is also fixedly mounted within the refractive index box 9 for refracting the laser beam emitted by the linear laser lamp 10 into a downward-pointing vertical laser beam. In this embodiment, the reflector 11 is mounted at a 45° angle. In this embodiment, a transparent panel 12 is also mounted at the bottom of the light guide box to shield the light guide chamber 8 and prevent dust from entering the light guide chamber 8. The angle of the vertical laser beam does not change after passing through the transparent panel 12. Both the refractive index box 9 and the light guide box are opaque.

[0031] When the present invention is used, the sleeve is first installed outside the punch 1 and the collar 6 is inserted upward from the bottom of the punch 1. Due to the action of the spring 15, the refraction box 9 and the light guide box below the four slides installed on the collar 6 remain in contact with the outer wall of the punch 1 during the process of moving upward from the bottom of the punch 1. When the collar 6 is in contact with the bottom of the sleeve, the collar 6 and the sleeve are fixed in position by bolts. At this time, the laser beams emitted by the straight line laser lamp 10 remain relatively stationary between the punch 1 and are located around the punch 1.

[0032] When the auto part 4 is placed on the support table 3 and the position is adjusted to align the punch 1 with the desired punching hole 5, the downwardly emitted laser beam will mark four points on the surface of the auto part 4. When the auto part 4 is moved so that the four points are evenly distributed circumferentially around the desired punching hole 5, it indicates that the punch 1 is aligned with the desired punching hole 5, which serves as a positioning indicator. This solves the problem of traditional parts that lack a device to indicate the position of the desired punching hole 5 during the adjustment process.

[0033] After the positioning is completed, the sleeve and the collar 6 are removed and the stamping process of the automobile part 4 can be carried out.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
