Description

Technical Field

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

[0002] Automotive parts processing equipment is a general term for specialized mechanical equipment and integrated systems used in the manufacturing process of automotive parts to achieve high-precision processing, assembly, and testing. Its core lies in ensuring that parts meet the stringent requirements of the automotive industry for quality, efficiency, and reliability through precision control and automation technology. Among them, the positioning device for automotive parts processing is a specialized process equipment used in the machining process system to determine the relative position of the workpiece and the tool and to prevent machining deviation through reliable clamping.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Traditional fixed positioning equipment, due to its non-adjustable height, is difficult to adapt to the differences in the reference surface of different sized parts, resulting in an angle or suspension between the clamping surface and the processing surface. This design defect can cause vibration, displacement or stress concentration during the processing, which in turn causes quality problems such as hole position misalignment and welding misalignment. Fixed positioning equipment can only process parts within a specific height range, which requires enterprises to configure multiple special equipment for different products, resulting in resource waste and increased costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the traditional fixed positioning equipment in the prior art has the disadvantage that it is difficult to adapt to parts of different sizes because the height is not adjustable. Therefore, we propose a positioning device for processing automotive parts.

[0005] To achieve the above objectives, this application adopts the following technical solution: a positioning device for processing automotive parts, comprising an operating table, a movable groove on the top of the operating table, a bidirectional screw rotatably connected inside the movable groove, a motor installed at one end of the bidirectional screw, two fixed rods slidably connected to the surface of the bidirectional screw, an adjusting support rod slidably connected inside the fixed rod, a positioning chuck installed on one side of the adjusting support rod, a fixed block fixedly connected to one side of the adjusting support rod, a structural groove on the side of the adjusting support rod near the fixed block, square blocks slidably connected to both sides inside the fixed block, an irregularly shaped card block fixedly connected to one side of the square block, the interior of the irregularly shaped card block slidably connected to the interior of the structural groove, several card slots on both sides inside the fixed rod, a magnetic block fixedly connected to the interior of the card slot, the surface of the irregularly shaped card block slidably connected to the interior of the card slot, and one side of the irregularly shaped card block magnetically attracted to the magnetic block.

[0006] Preferably, a sliding groove is fixedly connected to one side of the inside of the fixed rod, and a sliding block is provided on the side of the adjusting support rod away from the fixed block to cooperate with the sliding groove. The surface of the sliding groove is slidably connected to the inside of the sliding block.

[0007] Preferably, three rotating wheels are installed on the side of the sliding groove near the fixed block, and the surface of the rotating wheels is rotatably connected to the inside of the sliding groove.

[0008] Preferably, a square plate is fixedly connected inside the fixing block, and two springs are fixedly connected to both ends of the square plate, with the other end of the springs fixedly connected to the square block.

[0009] Preferably, the square block has irregularly shaped guide grooves at both the top and bottom, and the fixed block has irregularly shaped guide blocks fixedly connected to the top and bottom of both ends inside the fixed block. The surface of the irregularly shaped guide block is slidably connected to the inside of the irregularly shaped guide groove.

[0010] Preferably, an elastic pad is fixedly connected to the bottom of the adjusting support rod.

[0011] Preferably, the surface of the adjusting rod is provided with a scale.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, pressing the square blocks at both ends of the fixing block causes the square blocks to move the irregularly shaped locking block, disengaging it from the slot and returning it to the interior of the structural groove. At this point, the locking of the irregularly shaped locking block to the slot is released, thus releasing the limiting position of the adjusting rod within the fixing rod. This allows for adjustment of the height of the adjusting rod, thereby adjusting the height of the positioning clamp. After adjustment, the square blocks are reset, causing the irregularly shaped locking block to return to the slot. The irregularly shaped locking block, being made of metal, can magnetically connect with the magnetic block inside the slot, ensuring a more secure position within the slot. With increased stability, the adjusting rod is now repositioned within the fixed rod. This setting allows the positioning chuck height adjustment function to match the machining reference surface of automotive parts of different sizes, fundamentally eliminating positioning deviations caused by height differences. During machining, the bracket can dynamically adjust the support height according to the shape of the part and machining requirements, ensuring that the clamping surface and the machining surface remain horizontal at all times, avoiding vibration or displacement caused by tilting or suspension. This breaks the strict limitations of traditional fixed tooling on part size, and through the multi-position adjustment design, it can quickly adapt to the machining needs of automotive parts of different heights and shapes.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a positioning device for processing automotive parts, including an operating table 1. A movable groove 2 is formed on the top of the operating table 1. A bidirectional screw 3 is rotatably connected inside the movable groove 2. A motor 4 is installed at one end of the bidirectional screw 3. Two fixed rods slidably connect to the surface of the bidirectional screw 3. An adjusting support rod 6 is slidably connected inside the fixed rod 5. A positioning chuck 7 is installed on one side of the adjusting support rod 6. A fixing block 8 is fixedly connected to one side of the adjusting support rod 6. A structural groove 9 is formed on the side of the adjusting support rod 6 near the fixing block 8. The fixing block 8 contains... Square blocks 10 are slidably connected to both sides of the part. A shaped card block 11 is fixedly connected to one side of the square block 10. The interior of the shaped card block 11 is slidably connected to the interior of the structural groove 9. Several slots 12 are opened on both sides of the interior of the fixing rod 5. A magnetic block 13 is fixedly connected to the interior of the slot 12. The surface of the shaped card block 11 is slidably connected to the interior of the slot 12. One side of the shaped card block 11 is magnetically attracted to the magnetic block 13. By pressing the square blocks 10 at both ends of the fixing block 8, the square blocks 10 drive the shaped card block 11 to move, causing the shaped card block 11 to disengage from the interior of the slot 12. The irregularly shaped locking block 11 returns to the interior of the structural groove 9. At this time, the locking between the irregularly shaped locking block 11 and the locking groove 12 is released, thereby releasing the limiting position of the adjusting support rod 6 inside the fixed rod 5. The height position of the adjusting support rod 6 can be adjusted, thereby adjusting the height position of the positioning clamp 7. After the adjustment is completed, the square block 10 is reset, and the square block 10 drives the irregularly shaped locking block 11 back into the locking groove 12. The irregularly shaped locking block 11 is made of metal and can be magnetically connected with the magnetic block 13 inside the locking groove 12, making the irregularly shaped locking block 11 more stable inside the locking groove 12. At this time, the adjusting support rod 6... The positioning chuck 7 is repositioned within the fixed rod 5. This setting allows the height adjustment function of the positioning chuck 7 to match the machining reference surface of different sized automotive parts, fundamentally eliminating positioning deviations caused by height differences. During machining, the bracket can dynamically adjust the support height according to the shape of the part and machining requirements, ensuring that the clamping surface and the machining surface remain horizontal at all times, avoiding vibration or displacement caused by tilting or suspension. This breaks the strict limitation of traditional fixed tooling on the size of the parts. Through the multi-position adjustment design, it can quickly adapt to the machining requirements of automotive parts of different heights and shapes.

[0023] Reference Figure 2 and Figure 4 As shown in this embodiment: a sliding groove 14 is fixedly connected to one side inside the fixed rod 5, and a sliding block 15 is provided on the side of the adjusting support rod 6 away from the fixed block 8 to cooperate with the sliding groove 14. The surface of the sliding groove 14 is slidably connected to the inside of the sliding block 15. By sliding the sliding groove 14 inside the sliding block 15, the adjusting support rod 6 can be more stable when moving inside the fixed rod 5, and shaking can be avoided.

[0024] Reference Figure 4As shown in this embodiment: three rotating wheels 16 are installed on the side of the sliding groove 14 near the fixed block 8. The surface of the rotating wheels 16 is rotatably connected to the inside of the sliding groove 14. By setting the rotating wheels 16, the friction of the fixed rod 5 when it moves inside the adjusting support rod 6 can be reduced, making the movement of the adjusting support rod 6 smoother.

[0025] Reference Figure 5 As shown in this embodiment: a square plate 17 is fixedly connected inside the fixing block 8. Two springs 18 are fixedly connected to both ends of the square plate 17. The other end of the spring 18 is fixedly connected to the square block 10. By setting the spring 18, the elasticity of the spring 18 abuts against the square block 10, which can cause the square block 10 to drive the irregularly shaped card block 11 to automatically reset, simplifying the operation steps.

[0026] Reference Figure 5 As shown in this embodiment: the top and bottom of the square block 10 are provided with irregular guide grooves 19, and the top and bottom of both ends of the fixed block 8 are fixedly connected with irregular guide blocks 20. The surface of the irregular guide block 20 is slidably connected to the inside of the irregular guide groove 19. By making the irregular guide block 20 slide inside the irregular guide groove 19, the movement of the square block 10 can be linearly guided, so that the square block 10 will not deviate when it drives the irregular card block 11 to move, and the irregular card block 11 can accurately enter the inside of the card slot 12.

[0027] Reference Figure 3 As shown in this embodiment, an elastic pad 21 is fixedly connected to the bottom of the adjusting rod 6. By setting the elastic pad 21 at the bottom of the adjusting rod 6, it can effectively prevent the adjusting rod 6 from accidentally slipping out of the user's hand and colliding hard with the fixed rod 5 due to careless operation or mistakes during the adjustment process, thereby avoiding the resulting harsh noise and possible damage to the adjusting rod 6 and the fixed rod 5.

[0028] Reference Figure 3 As shown in this embodiment: a scale 22 is provided on the surface of the adjusting rod 6. By providing a scale 22 on the surface of the adjusting rod 6, the user can intuitively understand the adjustment height of the adjusting rod 6, ensuring that the adjustment heights of the two adjusting rods 6 are consistent, avoiding repeated measurements, and simplifying the operation steps.

[0029] Working principle: By pressing the square blocks 10 at both ends of the fixed block 8, the square blocks 10 drive the irregularly shaped locking block 11 to move, causing the irregularly shaped locking block 11 to disengage from the inside of the slot 12 and return to the inside of the structural groove 9. At this time, the locking of the irregularly shaped locking block 11 with the slot 12 is released, thereby releasing the limiting position of the adjusting support rod 6 inside the fixed rod 5, which allows for adjustment of the height position of the adjusting support rod 6, thereby achieving adjustment of the height position of the positioning clamp 7. After adjustment, the square blocks 10 are reset, and the square blocks 10 drive the irregularly shaped locking block 11 back into the slot 12. The irregularly shaped locking block 11 is made of metal and can interact with the magnetic block 13 inside the slot 12. The magnetic connection makes the irregularly shaped clamp 11 more stable inside the slot 12. At this time, the adjusting rod 6 is repositioned inside the fixed rod 5. Through this setting, the height adjustment function of the positioning chuck 7 matches the processing reference surface of automotive parts of different sizes, fundamentally eliminating the positioning deviation caused by height difference. During processing, the bracket can dynamically adjust the support height according to the shape of the part and processing requirements, ensuring that the clamping surface and the processing surface remain horizontal at all times, avoiding vibration or displacement caused by tilting or suspension. This breaks the strict limitation of traditional fixed tooling on the size of parts. Through the multi-level adjustment design, it can quickly adapt to different heights and shapes. For automotive parts processing, the sliding groove 14 within the sliding block 15 allows the adjusting rod 6 to move more stably within the fixed rod 5, preventing wobbling. The rotating wheel 16 reduces friction during the movement of the fixed rod 5 within the adjusting rod 6, making its movement smoother. The spring 18, by its elasticity, abuts against the square block 10, allowing it to automatically reset the irregularly shaped locking block 11, simplifying operation. The irregularly shaped guide block 20 sliding within the irregularly shaped guide groove 19 provides linear guidance for the movement of the square block 10, enabling it to move... The irregularly shaped locking block 11 will not deviate when moving, ensuring that it accurately enters the slot 12. By setting an elastic pad 21 at the bottom of the adjusting rod 6, it can effectively prevent the adjusting rod 6 from accidentally slipping out of the user's hand and colliding hard with the fixed rod 5 due to careless operation or mistakes during the adjustment process. This avoids the resulting harsh noise and potential damage to the adjusting rod 6 and the fixed rod 5. By setting a scale 22 on the surface of the adjusting rod 6, the user can intuitively understand the adjustment height of the adjusting rod 6, ensuring that the adjustment height of the two adjusting rods 6 is consistent, avoiding repeated measurements, and simplifying the operation steps.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
