Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a positioning fixture for opening holes in automotive headlight parts. Background Technology

[0002] In the automotive manufacturing process, the drilling of holes in headlight components is a crucial step, playing multiple roles. First, this step ensures that the headlights are accurately installed and function properly. Precision drilling provides accurate mounting positions for screws, clips, and other fasteners, guaranteeing a secure fit of the headlight onto the vehicle. Second, the holes allow wires to pass through smoothly, connecting the headlight to the vehicle's electrical system. These holes appear not only on the headlight housing but also on other key components such as reflectors and dust covers, collectively forming the foundation for headlight installation and functionality.

[0003] Patent CN219881112U discloses a punching fixture for automotive parts, including a base. A motor is fixedly mounted on the bottom surface of the base, and a worktable is fixedly mounted on the output end of the motor. A lower mold assembly for pre-positioning the automotive parts is fixedly mounted on the top surface of the worktable. A hydraulic rod drives the punching assembly and the vertical fixture to move vertically. A pressure block contacts the top surface of the automotive parts, and the hydraulic rod drives the punching assembly to continue moving vertically downwards. This causes a movable plate to move vertically on the surface of the hydraulic rod, stretching a spring. The spring's elastic force causes the pressure block to vertically fix the automotive parts, preventing them from shifting. The punching assembly then performs punching processing on the automotive parts.

[0004] However, the fixtures described above still have the following problems: most automotive headlight components are housing structures, a characteristic that poses a challenge to the punching process. During punching, once the drill bit contacts the surface of the component, it generates significant compressive force. This compressive force often causes the component to deform inwards within the fixture, leading to loosening of the component and severely affecting its stability. Therefore, the housing structure makes the stability during the hole-making process relatively poor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for opening holes in automotive headlight components, thereby improving the fixation effect of components during the hole-opening process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for opening holes in automotive headlight components, comprising a processing table, on which an outer clamping assembly and an inner clamping assembly are connected. The outer clamping assembly includes two outer clamping plates, and the inner clamping assembly includes two inner clamping plates. The two inner clamping plates are located between the two outer clamping plates. An outer clamping drive assembly is connected between the two outer clamping plates, and an inner clamping drive assembly is connected between the two inner clamping plates. A drive groove is provided through the processing table, and both the outer clamping drive assembly and the inner clamping drive assembly are located within the drive groove.

[0007] Furthermore, the external clamping drive assembly includes an external clamping bidirectional threaded rod and two external clamping drive blocks. One end of the external clamping bidirectional threaded rod is rotatably connected to one end of the drive groove, and the other end passes through the two external clamping drive blocks and the other end of the drive groove in sequence, and is connected to an external clamping drive motor. The external clamping drive motor is fixedly connected to the end of the processing table through a motor base. The external clamping bidirectional threaded rod is threadedly connected to the two external clamping drive blocks. Both external clamping drive blocks are slidably connected to the drive groove. The two external clamping drive blocks are fixedly connected to the bottom of the two external clamping plates respectively.

[0008] Furthermore, the inner clamping drive assembly includes an inner clamping bidirectional threaded rod and two inner clamping drive blocks. The two inner clamping drive blocks are fixedly connected to the bottom of the two inner clamping plates respectively. Both inner clamping drive blocks are slidably connected to the drive groove. One end of the inner clamping bidirectional threaded rod is rotatably connected to the end of the drive groove away from the outer clamping drive motor. The other end passes through the two inner clamping drive blocks and the other end of the drive groove in sequence, and is connected to the inner clamping drive motor. The inner clamping drive motor is fixedly connected to the end of the processing table away from the outer clamping drive motor through a motor base. The inner clamping bidirectional threaded rod is threadedly connected to the two inner clamping drive blocks.

[0009] Furthermore, there are two internal clamping bidirectional threaded rods, and the two internal clamping bidirectional threaded rods are respectively located on both sides of the external clamping bidirectional threaded rod. The driven gear is fixedly connected to one end of the two internal clamping bidirectional threaded rods that passes through the drive groove. A driving gear meshes between the two driven gears. The output shaft of the internal clamping drive motor is fixedly connected to the driving gear, and the output shaft of the external clamping drive motor is fixedly connected to the end of the external clamping bidirectional threaded rod away from the internal clamping drive motor.

[0010] Furthermore, the external clamping bidirectional threaded rod is threadedly connected to the middle position of the external clamping drive block, and the two internal clamping bidirectional threaded rods are respectively threadedly connected to both ends of the internal clamping drive block. The side walls at both ends of the external clamping drive block are provided with first through holes, and the two first through holes are respectively fitted with two internal clamping bidirectional threaded rods. The middle position of the internal clamping drive block is provided with a second through hole, and the second through hole is fitted with an external clamping bidirectional threaded rod.

[0011] Furthermore, limit blocks are fixedly connected to both sides of the two outer clamping drive blocks and the two inner clamping drive blocks, and limit grooves are opened on both sides of the drive groove, with several limit blocks slidably connected to the two limit grooves respectively.

[0012] Furthermore, external anti-slip pads are fixedly connected to the adjacent sides of the two outer clamping plates, and internal anti-slip pads are fixedly connected to the opposite sides of the two inner clamping plates.

[0013] Furthermore, support legs are fixedly connected to the four corners of the bottom of the processing table.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This positioning fixture for opening holes in automotive headlight components uses two inner clamping plates to press the inner side of the component's housing outwards, and two outer clamping plates to press the outer side of the component's housing inwards, thereby clamping and fixing both ends of the component's housing. This makes it less likely for the component's housing to move on the machining table during hole opening, improving the firmness and stability of the hole opening positioning and fixing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5A positioning fixture for opening holes in automotive headlight components includes a processing table 1. An outer clamping assembly and an inner clamping assembly are connected to the processing table 1. The outer clamping assembly includes two outer clamping plates 2, and the inner clamping assembly includes two inner clamping plates 3. The two inner clamping plates 3 are located between the two outer clamping plates 2. An outer clamping drive assembly is connected between the two outer clamping plates 2, and an inner clamping drive assembly is connected between the two inner clamping plates 3. A drive groove 101 is provided through the processing table 1, and both the outer clamping drive assembly and the inner clamping drive assembly are located in the drive groove 101.

[0024] like Figures 1 to 5 As shown, the main improvement of this utility model lies in its ability to clamp shell-shaped parts more firmly and stably, thereby improving the stability of the machining of openings in the shell of the parts. Figures 1 to 5 As shown, the positioning fixture for opening holes in automotive headlight components in this utility model is used by placing the opening edge of the component housing towards the processing table 1, with the two ends of the opening of the component housing located between two sets of outer clamping plates 2 and inner clamping plates 3 respectively. Then, the two outer clamping plates 2 are driven by the outer clamping drive assembly to gradually approach each other and finally abut against the two ends of the outer wall of the component housing. Then, the two inner clamping plates 3 are driven by the inner clamping drive assembly to gradually move away from each other and finally abut against the inner wall of the component housing where it is clamped by the two outer clamping plates 2. At this time, a single inner clamping plate 3 and an outer clamping plate 2 cooperate to clamp the end corners of the component housing. With the cooperation of another outer clamping plate 2 and an inner clamping plate 3, the two ends of the component housing can be clamped and fixed. When the component housing is drilled, since the two sets of outer clamping plates 2 and inner clamping plates 3 clamp and fix the two ends of the component housing, and the bottom of the component housing abuts against the processing table 1, even if the housing is squeezed by the drill bit, it is ensured that the component housing will not shift on the processing table 1, thus improving the stability of the drilling process.

[0025] like Figures 1 to 5 As shown, the external clamping drive assembly includes an external clamping bidirectional threaded rod 4 and two external clamping drive blocks 5. One end of the external clamping bidirectional threaded rod 4 is rotatably connected to one end of the drive groove 101, and the other end passes through the two external clamping drive blocks 5 and the other end of the drive groove 101, and is connected to an external clamping drive motor 8. The external clamping drive motor 8 is fixedly connected to the end of the processing table 1 through a motor base. The external clamping bidirectional threaded rod 4 is threadedly connected to the two external clamping drive blocks 5, and both external clamping drive blocks 5 are slidably connected to the drive groove 101. The two external clamping drive blocks 5 are respectively fixedly connected to the bottom of the two external clamping plates 2. When the external clamping drive motor 8 is started, the external clamping bidirectional threaded rod 4 rotates in the drive groove 101, which synchronously drives the two external clamping drive blocks 5 to move relative to each other at both ends of the drive groove 101, thereby realizing the relative adjustment and movement of the two external clamping plates 2, which can stably clamp and fix the part housing in the middle position of the processing table 1.

[0026] like Figures 1 to 5As shown, the inner clamping drive assembly includes an inner clamping bidirectional threaded rod 6 and two inner clamping drive blocks 7. The two inner clamping drive blocks 7 are fixedly connected to the bottom of the two inner clamping plates 3 respectively. Both inner clamping drive blocks 7 are slidably connected to the drive groove 101. One end of the inner clamping bidirectional threaded rod 6 is rotatably connected to the end of the drive groove 101 away from the outer clamping drive motor 8. The other end passes through the two inner clamping drive blocks 7 and the other end of the drive groove 101 in sequence, and is connected to the inner clamping drive motor 9. The inner clamping drive motor 9 is fixedly connected to the end of the processing table 1 away from the outer clamping drive motor 8 through the motor base. The inner clamping bidirectional threaded rod 6 is threadedly connected to the two inner clamping drive blocks 7. The inner clamp drive motor 9 is started, which drives the inner clamp bidirectional threaded rod 6 to rotate in the drive groove 101. Simultaneously, it drives the two inner clamp drive blocks 7 to move relative to each other at both ends in the drive groove 101. This allows for relative adjustment and movement of the two inner clamp plates 3. The inner side of the component housing, which is clamped and fixed by the two outer clamp plates 2, can be pressed onto the two outer clamp plates 2, thereby clamping and fixing the two ends of the component housing. This prevents the component housing from detaching from the outer clamp plates 2 due to inward concavity, or from detaching from the inner clamp plates 3 due to outward expansion of the component housing. It ensures that the two ends of the component housing are always clamped between the outer clamp plates 2 and the inner clamp plates 3.

[0027] like Figures 1 to 5 As shown, there are two internal clamping bidirectional threaded rods 6, located on either side of the external clamping bidirectional threaded rod 4. A driven gear 10 is fixedly connected to one end of each of the two internal clamping bidirectional threaded rods 6 that passes through the drive groove 101. A driving gear 11 meshes between the two driven gears 10. The output shaft of the internal clamping drive motor 9 is fixedly connected to the driving gear 11, and the output shaft of the external clamping drive motor 8 is fixedly connected to the end of the external clamping bidirectional threaded rod 4 away from the internal clamping drive motor 9. Starting the internal clamping drive motor 9 drives the driving gear 11 to rotate, which in turn drives the two driven gears 10 to rotate simultaneously through gear meshing, thus synchronously driving the two internal clamping bidirectional threaded rods 6 to rotate. This allows the internal clamping drive block 7 to move stably within the drive groove 101.

[0028] like Figures 1 to 5As shown, the external clamping bidirectional threaded rod 4 is threadedly connected to the middle position of the external clamping drive block 5, and the two internal clamping bidirectional threaded rods 6 are respectively threadedly connected to the two ends of the internal clamping drive block 7. The side walls at both ends of the external clamping drive block 5 are provided with first through holes 501, and the two internal clamping bidirectional threaded rods 6 are respectively fitted into the two first through holes 501. The middle position of the internal clamping drive block 7 is provided with a second through hole 701, and the external clamping bidirectional threaded rod 4 is fitted into the second through hole 701. When the outer clamping bidirectional threaded rod 4 rotates and drives the outer clamping drive block 5 to slide in the drive groove 101, the second through hole 701 in the middle of the inner clamping drive block 7 is fitted on the outside of the outer clamping bidirectional threaded rod 4, so that the rotating outer clamping bidirectional threaded rod 4 and the inner clamping drive block 7 do not come into contact with each other. The first through hole 501 on the side of the outer clamping drive block 5 is fitted on the outside of the inner clamping bidirectional threaded rod 6, which also ensures that the inner clamping bidirectional threaded rod 6 does not come into contact with the outer clamping drive block 5 when it rotates, so that the inner clamping drive assembly and the outer clamping drive assembly do not interfere with each other and are simultaneously in the drive groove 101.

[0029] like Figures 1 to 5 As shown, limit blocks 14 are fixedly connected to both sides of the two outer clamping drive blocks 5 and the two inner clamping drive blocks 7. Limit grooves 102 are formed on both sides of the drive groove 101, and several limit blocks 14 are slidably connected to the two limit grooves 102 respectively. By allowing the limit blocks 14 to slide within the limit grooves 102, the outer clamping drive blocks 5 and the inner clamping drive blocks 7 are more stable when sliding within the drive groove 101, and are less prone to vertical shaking, thereby improving the stability and firmness of clamping and fixing the component housing.

[0030] like Figures 1 to 5 As shown, external anti-slip pads 12 are fixedly connected to the adjacent sides of the two outer clamping plates 2, and internal anti-slip pads 13 are fixedly connected to the opposite sides of the two inner clamping plates 3. When the outer clamping plates 2 and the inner clamping plates 3 are clamped on the inner and outer sides of the component housing, the external anti-slip pads 12 and the inner anti-slip pads 13 can increase the frictional force between the outer and inner sides of the component housing, thereby improving the stability of clamping and fixing the component housing.

[0031] like Figures 1 to 5 As shown, support legs 15 are fixedly connected to the four corners of the bottom of the processing table 1. The support legs 15 raise the processing table 1, improving the convenience of the drilling operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
