Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive sunroof guide rail positioning technology, and in particular to an automotive sunroof guide rail positioning clamp. Background Technology
[0002] Currently, positioning fixtures are used when drilling, grinding, and cutting the guide rail body of car sunroofs. The car sunroof guide rail body can be stably processed after being clamped with the fixture.
[0003] According to Chinese Patent Publication No. CN219633157U, a fixture for processing automotive sunroof guide rails is provided, relating to the field of automotive sunroof guide rail body processing technology. It includes a fixed base with a movable assembly on its top. In this invention, when in use, the guide rail body is placed on top of the positioning plate and positioned inside the two positioning frames. At this time, the guide rail body is exactly in the middle position of the fixed base. The external power supply of the motor is turned on, driving the threaded rod to rotate, which in turn drives the movable plate and the base plate to move towards the positioning block. Simultaneously, the positioning plate and the guide rail body move. When one outer surface of the base plate contacts the outer surface of the positioning block, the motor is stopped. Under the positioning of the positioning block, the guide rail body moves to the center of the top of the fixed base. Under the action of the clamping mechanism, the guide rail body at the center is clamped and fixed, thereby achieving the positioning effect. Manual placement is not required, improving the positioning accuracy.
[0004] Traditional positioning fixtures, after fixing the guide rail, require the fixture to be removed before moving it to change the fixed position according to processing requirements. At this point, the guide rail is no longer fixed and is easily displaced by external influences. When fixing it again, the position of the guide rail does not need to be readjusted, which affects processing efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a positioning fixture for automotive sunroof guide rails, which can avoid the situation where, after fixing the guide rail with a traditional positioning fixture, if you want to change the fixed position according to processing requirements, you need to first contact the fixing of the guide rail and then move the fixture. At this time, the guide rail is no longer fixed and is easily displaced by external influences. When fixing it again, there is no need to readjust the position of the guide rail, which affects the processing efficiency.
[0006] This utility model provides a positioning fixture for a car sunroof guide rail, including a positioning platform. A groove is provided on the upper side of the positioning platform, and a clamping component is slidably connected in the groove. A positioning mechanism is movably connected to one side of the clamping component. When the positioning mechanism positions the guide rail body, it adjusts the clamping position of the clamping component while keeping the guide rail body stationary.
[0007] Preferably, the clamping assembly includes a positioning frame, the lower end of which is slidably connected to a track provided on the upper side of the positioning platform.
[0008] Preferably, sliders are provided on both sides of the lower end of the positioning frame, and the two sliders slide in two grooves respectively.
[0009] Preferably, each of the two grooves is rotatably provided with a lead screw, and the two lead screws are respectively threadedly connected to the two sliders.
[0010] Preferably, the upper end of the positioning frame is provided with symmetrical limiting grooves, and each of the two limiting grooves has a sliding limiting block. Each of the two limiting blocks is connected to a rack on its lower side. The two racks mesh with the two sides of a gear rotating on the positioning frame, and the gear is driven by a motor.
[0011] Preferably, each of the two racks is provided with a connecting rod on one side, and the lower end of the connecting rod is provided with symmetrical positioning wheels.
[0012] Preferably, the positioning mechanism includes a horizontal plate, a cylinder is mounted on the lower side of the horizontal plate, and a positioning plate is connected to the piston end of the cylinder.
[0013] Preferably, both ends of the horizontal plate are provided with vertical rods, and the lower end of the vertical rods is threadedly connected to a positioning rod.
[0014] Preferably, extension rods are provided on both sides of the horizontal plate and the vertical rod, and hollow sleeves are symmetrically provided at both the upper and lower ends of the positioning frame, with the extension rods slidably disposed within the hollow sleeves.
[0015] Preferably, the lower end of the vertical rod is aligned with the upper side of the track.
[0016] This utility model provides a positioning fixture for an automotive sunroof guide rail, which, compared with the prior art, offers the following advantages:
[0017] 1. This utility model uses a clamping assembly to fix both sides of the guide rail body, so that the guide rail body remains stable during processing. At the same time, a positioning mechanism is used to assist the clamping assembly, clamping the guide rail body from the inside to the outside, further improving its stability. When it is necessary to change the clamping position, the positioning mechanism can be used to fix the guide rail body before moving the clamping assembly. This can prevent the guide rail body from being in an unfixed state when the clamping assembly moves, which would affect subsequent processing.
[0018] 2. The clamping assembly of this utility model uses rollers to fix both sides of the guide rail body. The rolling friction between the rollers and the guide rail body is relatively small, which can significantly reduce friction. The positioning mechanism uses a positioning plate to contact the guide rail body, resulting in a large positioning area. The fixing method of the two not only improves the fixing effect but also avoids damage to the guide rail body. Attached Figure Description

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0031] Please refer to Figures 1-8This utility model embodiment provides a positioning fixture for a car sunroof guide rail, including a positioning platform 1. A groove 3 is provided on the upper side of the positioning platform 1, and a clamping component is slidably connected in the groove 3. The clamping component clamps both sides of the guide rail body 2.
[0032] Specifically, the clamping assembly includes a positioning frame 5, the lower end of which is slidably connected to a track on the upper side of the positioning platform 1. At the same time, sliders 6 are provided on both sides of the lower end of the positioning frame 5. The two sliders 6 slide in two grooves 3 respectively, and the position of the positioning frame 5 can be adjusted by sliding the sliders 6.
[0033] Furthermore, a lead screw 4 is rotatably installed in each of the two slides 3. The two lead screws 4 are threadedly connected to the two sliders 6 respectively. The lead screws 4 are driven by a motor. When the lead screws 4 rotate, the sliders 6 can move automatically, which improves the efficiency of changing the position of the positioning frame 5.
[0034] Furthermore, symmetrical limiting grooves 7 are provided at the upper end of the positioning frame 5. Limiting blocks 10 slide in both limiting grooves 7. Racks 9 are connected to the lower side of both limiting blocks 10. The two racks 9 mesh with the two sides of the gear 8 rotating on the positioning frame 5 respectively. The gear 8 rotates after being driven by the motor, causing the racks 9 on both sides to move away from or closer to each other.
[0035] Since there are connecting rods 11 on one side of both racks 9, and symmetrical positioning wheels 12 are rotatably provided at the lower end of the connecting rods 11, when the racks 9 approach each other, the positioning wheels 12 on both sides will position and clamp the sides of the guide rail body 2.
[0036] In addition, a positioning mechanism is movably connected to one side of the clamping assembly. The positioning mechanism includes a horizontal plate 15, and a cylinder 17 is installed on the lower side of the horizontal plate 15. The piston end of the cylinder 17 is connected to a positioning plate 18. The cylinder 17 can push the positioning plate 18 down to position the guide rail body 2.
[0037] To improve the stability of the horizontal plate 15, vertical rods 16 are provided at both ends of the horizontal plate 15. The lower end of the vertical rod 16 is threadedly connected to a positioning rod 19. At the same time, the lower end of the vertical rod 16 is aligned with the upper side of the track. The positioning rod 19 can be inserted into the insertion hole opened at the upper end of the track. Multiple insertion holes are provided to meet the movement requirements of the vertical rod 16.
[0038] Furthermore, extension rods 14 are provided on both sides of the horizontal plate 15 and the vertical rod 16, and hollow sleeves 13 are symmetrically provided at both the upper and lower ends of the positioning frame 5. The extension rods 14 are slidably disposed in the hollow sleeves 13. By sliding the extension rods 14 in the hollow sleeves 13, the stability of the positioning mechanism is improved.
[0039] Furthermore, when the positioning mechanism positions the guide rail body 2, the clamping assembly adjusts its clamping position while the guide rail body 2 remains stationary by rotating the lead screw 4. At this time, the extension rod 14 slides out of the hollow sleeve 13. After the movement ends, the positioning mechanism can be moved to the side of the clamping assembly.
[0040] In summary, the working principle of the automotive sunroof guide rail positioning fixture of this utility model embodiment is as follows: the clamping components are used to fix both sides of the guide rail body 2, so that the guide rail body 2 remains stable during processing. At the same time, the positioning mechanism is used to assist the clamping components in clamping the guide rail body 2 from the inside to the outside. When it is necessary to replace the clamping components, the positioning mechanism can be used to fix the guide rail body 2 before the clamping components are moved. This can prevent the guide rail body 2 from being in an unfixed state when the clamping components are moved, which would affect subsequent processing.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
