Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, specifically to a positioning device for hot stamping automotive headlight parts. Background Technology
[0002] Hot stamping is a special printing process that does not use ink. It involves applying electroplated aluminum foil to the surface of a substrate under specific temperature and pressure. A hot stamping machine is the equipment used to perform this process. Currently, hot stamping is commonly used on automotive lighting components to imprint information such as the manufacturer and production date onto the surface of the components, enhancing the appearance of the lights and making them easily identifiable to users.
[0003] Chinese patent CN209987551U discloses a hot stamping machine for automotive parts. The machine uses a heating head that is fixedly mounted on a support plate and slides vertically to perform hot stamping on automotive parts placed on the support plate. The machine is sealed on all four sides by a heat dissipation component and a transparent frame, which provides a certain degree of protection.
[0004] However, when performing hot stamping on automotive headlight components, due to the curved surfaces on these components, if hot stamping is performed on a part of the component that is away from the curved surface, the curved surface of the component will come into contact with the support plate. In this case, the component will not be able to maintain a stable position on the support plate, resulting in inconsistent hot stamping positions and causing problems with the hot stamping results. Utility Model Content
[0005] Based on this, it is necessary to provide a positioning device for hot stamping of automotive lamp components to address the existing technical problems. The device uses a support plate and a support column to provide multiple points of support on the curved surface of the automotive lamp component. The movement of the movable strip and the support column allows it to adapt to different automotive lamp components, and a positioning ring is used for secondary positioning.
[0006] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:
[0007] A positioning device for hot stamping automotive lamp components is provided, comprising a support plate, movable strips, a support column, and positioning rings. Two movable strips are slidably mounted on the support plate, arranged parallel to each other. The sliding direction of the movable strips is parallel to the line connecting their centers. The support column is vertically connected to the movable strips via a telescopic rod. The axis of the support column is parallel to the length direction of the connected movable strip. The relative position of the support column to the support plate can be fixed. Two positioning rings are slidably mounted on the support column along its axial direction.
[0008] Preferably, the support plate is U-shaped, with the opening of the support plate opened horizontally, and the movable strip is slidably disposed inside the support plate, with both ends of the movable strip able to extend to the outside of the support plate.
[0009] Preferably, the positioning device further includes a fixing strip and a connecting strip. The fixing strip is fixedly disposed inside the support plate and is located between two movable strips. One end of the connecting strip is rotatably connected to the end of the movable strip, and the other end of the connecting strip is rotatably connected to the end of the fixing strip. The rotation axes at both ends of the connecting strip are parallel to the axis of the support column. A first threaded rod is threadedly connected to the connecting strip. The first threaded rod is rotatably connected to the connecting strip. The axis of the first threaded rod is parallel to the axis of the support column. The end of the first threaded rod away from the inside of the support plate extends to the outside of the support plate and is fixedly connected to a first handwheel.
[0010] Preferably, a sponge pad is fixedly provided at the end of the first handwheel near the support plate.
[0011] Preferably, the positioning device further includes a torsion spring, which is fixedly disposed between the connector and the fixing strip.
[0012] Preferably, the support plate also includes gears and a transmission belt. There are two gears, which are rotatably arranged inside the support plate along the sliding direction of the movable bar. The axis of the gears is vertically arranged. The transmission belt is connected to the two gears. Two fixed protrusions are fixedly arranged on the transmission belt to divide the transmission belt evenly. The movable bar has fixed holes for the fixed protrusions to be inserted.
[0013] Preferably, a sponge sleeve is fixedly fitted onto the support column.
[0014] Preferably, a second threaded rod coaxial with the support column is rotatably provided inside the support column. The second threaded rod is a bidirectional threaded rod, with both ends extending to the outside of the support column and fixedly connected to a second handwheel. The two threads of the second threaded rod are respectively threadedly engaged with a positioning ring.
[0015] The advantages of this utility model compared to the prior art are:
[0016] This invention achieves multi-point support on the curved surface of the vehicle light component by using the support plate top surface in conjunction with the support column. The movement of the movable strip and support column enables it to adapt to different vehicle light components. The positioning ring enables secondary positioning. Therefore, regardless of which side of the vehicle light component is being hot-stamped, the positioning device can stably and quickly fix the position of the vehicle light component, thereby ensuring that the hot-stamping work can be carried out stably and improving the pass rate of hot-stamped products.

Detailed Implementation
[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0025] See Figures 1-3 As shown: A positioning device for hot stamping of automotive lamp components includes a support plate 1, movable strips 2, support columns 3, and positioning rings 4. The movable strips 2 are slidably mounted on the support plate 1. There are two movable strips 2, which are arranged in parallel. The sliding direction of the movable strips 2 is parallel to the line connecting their centers. The support column is vertically connected to the movable strips 2 via a telescopic rod 31. The axis of the support column 3 is parallel to the length direction of the connected movable strip 2. The relative position of the support column 3 with respect to the support plate 1 can be fixed. The positioning rings 4 are slidably mounted on the support column 3 along its axis. There are two positioning rings 4.
[0026] The curved surface of the headlight component is placed face down at the center of the support plate 1. Then, the movable strips 2 at both ends of the support plate 1 are brought closer together, while the support column 3 is moved vertically upwards. When the two support columns 3 contact the curved surface of the headlight component, their positions are fixed. Then, the two positioning rings 4 on the same support column 3 are brought closer together from both ends of the support column 3 until the positioning rings 4 contact the side wall of the headlight component. Compared with the prior art, the support plate 1 and support column 3 of this invention provide multiple points of support on the curved surface of the headlight component. The movement of the movable strips 2 and support column 3 allows it to adapt to different headlight components. The positioning rings 4 provide secondary positioning, so that the positioning device can stably and quickly fix the position of the headlight component regardless of which side of the headlight component is being hot-stamped, thus ensuring that the hot-stamping work can be carried out stably and improving the pass rate of hot-stamped products.
[0027] See Figures 2-3 As shown: the support plate 1 is in the shape of a square, the opening of the support plate 1 is opened in the horizontal direction, the movable strip 2 is slidably disposed inside the support plate 1, and the two ends of the movable strip 2 can extend to the outside of the support plate 1.
[0028] Compared with the prior art, the support plate 1 of this utility model defines its own shape, so that there will be no groove on the top surface of the support plate 1, ensuring stable contact between the support plate 1 and the vehicle lamp components.
[0029] See Figures 2-3 As shown: The positioning device also includes a fixing strip 5 and a connecting strip 6. The fixing strip 5 is fixedly installed inside the support plate 1 and is located between two movable strips 2. One end of the connecting strip 6 is rotatably connected to the end of the movable strip 2, and the other end of the connecting strip 6 is rotatably connected to the end of the fixing strip 5. The rotation axes of both ends of the connecting strip 6 are parallel to the axis of the support column 3. A first threaded rod 51 is threadedly connected to the connecting strip 6. The first threaded rod 51 is rotatably connected to the connecting strip 6. The axis of the first threaded rod 51 is parallel to the axis of the support column 3. The end of the first threaded rod 51 away from the inside of the support plate 1 extends to the outside of the support plate 1 and is fixedly connected to a first handwheel 52.
[0030] Once the support column 3 has moved to the appropriate position, the first handwheel 52 drives the first threaded rod 51 to rotate. At this time, the first handwheel 52 moves closer to the support plate 1 along the axis of the first threaded rod 51 under the drive of the first threaded rod 51. The first handwheel 52 will then squeeze and cooperate with the fixing strip 5 to clamp the connecting strip 6. Compared with the prior art, the first handwheel 52 of this utility model, in cooperation with the first threaded rod 51, rotates and continuously squeezes the fixing strip 5, so that the position of the support column 3 relative to the support plate 1 can be fixed at any time.
[0031] See Figures 2-3As shown: A sponge pad 53 is fixedly installed at the end of the first handwheel 52 near the support plate 1.
[0032] Compared with the prior art, the sponge pad 53 of this utility model replaces the first handwheel 52 and directly contacts the connecting bar 6, thereby avoiding damage to the connecting bar 6 when the first handwheel 52 squeezes it.
[0033] See Figures 2-3 As shown: The positioning device also includes a torsion spring 7, which is fixedly disposed between the connector and the fixing strip 5.
[0034] When there is no external force, the torsion spring 7 is in its normal state (naturally extended state). At this time, the gap between the movable strip 2 and the support column 3 is the smallest. Compared with the prior art, the torsion spring 7 of this utility model limits the relative distance between the support column 3 and the movable strip 2, thereby ensuring that there is no obstruction when placing the vehicle light components on the support plate 1.
[0035] See Figure 3 , Figure 5 and Figure 6 As shown: The support plate 1 also includes gears 11 and transmission belts 12. There are two gears 11, which are rotated and arranged inside the support plate 1 at intervals along the sliding direction of the movable bar 2. The axis of the gears 11 is vertically arranged. The transmission belt 12 is connected to the two gears 11. Two fixed protrusions 13 are fixedly arranged on the transmission belt 12 to divide the transmission belt 12 evenly. The movable bar 2 is provided with fixing holes 21 for the fixed protrusions 13 to be inserted.
[0036] When one movable bar 2 is controlled to move, the movable bar 2 drives the transmission belt 12 to move through the cooperation of the fixing hole 21 and the fixing protrusion 13, thereby causing the other movable bar 2 to move in the opposite direction to the first movable bar 2. Compared with the prior art, the transmission belt 12, the fixing protrusion 13 and the fixing hole 21 of this utility model cooperate to make the two movable bars 2 move in opposite directions synchronously, thereby reducing the time spent on operation.
[0037] See Figure 2 , Figure 3 and Figure 5 As shown: A sponge sleeve 32 is fixedly fitted on the support column 3.
[0038] Compared with the prior art, the support column 3 of this utility model contacts the vehicle lamp components through the sponge sleeve 32, thereby preventing the vehicle lamp components from sliding between the support column 3 and the support column 3.
[0039] See Figure 3 and Figure 5As shown: A second threaded rod 33, coaxial with the support column 3, is rotatably installed inside the support column 3. The second threaded rod 33 is a bidirectional threaded rod, with both ends extending to the outside of the support column 3 and fixedly connected to a second handwheel 34. The two threads of the second threaded rod 33 are respectively threadedly engaged with a positioning ring 4.
[0040] Compared with the prior art, the second threaded rod 33 of this utility model rotates to drive the positioning ring 4 to move, thereby ensuring that the positioning ring 4 can fix its position and not shift after moving.
[0041] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
