Description

Technical Field

[0001] This utility model relates to the field of sealing component positioning technology, and in particular to an automotive sealing component positioning device. Background Technology

[0002] Key automotive components are fitted with seals to prevent the intrusion of dust, gas, and water. During the manufacturing process, the burrs on these seals need to be trimmed. Currently, the trimming process typically involves using a positioning device to fix the seal before performing a circumferential trimming. However, existing positioning devices can only clamp the seal and cannot keep it aligned with the positioning device on the same axis. This can lead to deviations during the mechanical trimming process, resulting in over- or under-cutting, which in turn affects the sealing performance of the automotive seals. Utility Model Content

[0003] The purpose of this invention is to solve the shortcomings of existing technologies, such as the difficulty in aligning the seal with the positioning device on the same axis, and the occurrence of over-cutting or under-cutting during mechanical trimming. Therefore, this invention proposes an automotive seal positioning device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A positioning device for automotive seals is designed, comprising a sleeve block with a through hole for a tubular seal. A multi-directional positioning component is fixedly connected to the bottom surface of the sleeve block. The multi-directional positioning component includes a support platform, which is fixedly connected to the sleeve block. A rotating frame is symmetrically fixedly connected to the surface of the support platform. A first positioning post is rotatably connected to the rotating frame, and a second positioning post is rotatably connected to the first positioning post. Gears are fixedly connected to the first and second positioning posts, and the gears are coaxially arranged with the rotating frame. Each first and second positioning post has the same length. A synchronous drive assembly is fixedly connected to the surface of the sleeve block.

[0006] Preferably, the synchronous drive assembly includes a U-shaped frame, in which a bidirectional reciprocating lead screw is rotatably connected. Two sliders are symmetrically arranged on the bidirectional reciprocating lead screw. The sliders are slidably connected to the U-shaped frame. An L-shaped rod is fixedly connected to the bottom surface of the slider. Each L-shaped rod has a guide member fixedly connected to its end for driving the gear to rotate.

[0007] Preferably, the guide includes a Z-shaped plate, which is fixedly connected to an L-shaped rod. Two racks are fixedly connected to the side of the Z-shaped plate. One rack meshes with a gear on a first positioning post, and the other rack meshes with a gear on a second positioning post.

[0008] Preferably, each of the first positioning stakes, the second positioning stakes, and the support platform forms the same angle.

[0009] Preferably, both the first positioning post and the second positioning post are fixedly connected to a positioning block at their ends. The positioning block is used to position the tubular seal and is arc-shaped.

[0010] Preferably, a rotating wheel is fixedly connected to the end of the bidirectional reciprocating lead screw.

[0011] The present invention provides a positioning device for automotive seals, which has the following advantages: By rotating a rotating wheel, the wheel drives a bidirectional reciprocating screw to rotate. The screw drives two sliders to move in opposite directions. The movement of the sliders causes a Z-shaped plate to move. Two racks on the Z-shaped plate drive their corresponding gears to rotate, thus enabling the first and second positioning posts to rotate in opposite directions along the rotating frame. Positioning blocks at the ends of the first and second positioning posts clamp the seal body passing through the perforation and position it coaxially with the perforation. This avoids the seal body's position being unstable during trimming, preventing over- or under-cutting during the trimming process, thereby improving the production quality of the seal body.

[0019] 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.

[0020] Example 1

[0021] Reference Figure 1-5 This utility model is a positioning device for automotive seals, including a sleeve block 1. The sleeve block 1 has a through hole for passing through a tubular seal. A multi-directional positioning component is fixedly connected to the bottom surface of the sleeve block 1. The multi-directional positioning component includes a support platform 2, which is fixedly connected to the sleeve block 1. A rotating frame 3 is symmetrically fixedly connected to the surface of the support platform 2. A first positioning post 4 is rotatably connected to the rotating frame 3, and a second positioning post 5 is rotatably connected to the first positioning post 4. The rotating frame 3 has the same axis as the first positioning post 4 and the second positioning post 5. The first positioning post 4 and the second positioning post 5 can rotate within the rotating frame 3 to clamp the tubular seal.

[0022] Gears 6 are fixedly connected to the first positioning post 4 and the second positioning post 5. The gears 6 are coaxially arranged with the rotating frame 3. Each first positioning post 4 and the second positioning post 5 has the same length. A synchronous drive component is fixedly connected to the surface of the sleeve block 1. Each first positioning post 4, the second positioning post 5 and the support platform 2 form the same angle.

[0023] The operation process of this embodiment is as follows: the tubular seal to be trimmed is passed through the perforation in the sleeve block 1. The first positioning post 4 and the second positioning post 5 are symmetrically arranged on both sides of the seal body 15 along the axis of the seal body 15. The first positioning post 4 and the second positioning post 5 are rotated synchronously in opposite directions. The first positioning post 4 and the second positioning post 5 rotate along the axis of the rotating frame 3. When the multiple sets of first positioning posts 4 and second positioning posts 5 rotate, their ends gradually come into close contact with the seal, clamping the seal at multiple points and positioning it at the axial position of the sleeve block 1. Through the two sets of symmetrically arranged first positioning posts 4 and second positioning posts 5, the seal body 15 can be accurately positioned on the same axis as the sleeve block 1, avoiding the situation where the axis of the seal body 15 is not fixed during the annular trimming process, and the seal body 15 is cut too much or too little during the trimming process.

[0024] During the reverse synchronous rotation, each gear 6 is on the same axis as its corresponding first positioning post 4 and second positioning post 5. By synchronously rotating two adjacent gears 6 in the opposite direction, the first positioning post 4 and the second positioning post 5 can be driven to position the sealing body 15. The first positioning post 4 and the second positioning post 5 form the same angle with the support platform 2, and always maintain synchronous reverse rotation. This ensures that the positioning point of the tubular sealing part remains consistent after positioning. When positioning sealing body 15 of different diameters, it can be kept in the same axis as the sleeve block 1 after positioning, avoiding the occurrence of over- or under-trimming during annular trimming.

[0025] Example 2

[0026] Because the gears 6 inside the first positioning post 4 and the second positioning post 5 need to rotate in opposite directions, the driving process is rather complicated. Therefore, please refer to [the relevant documentation]. Figure 4-5 Based on the first specific embodiment, the synchronous drive assembly includes a U-shaped frame 10, a bidirectional reciprocating lead screw 11 is rotatably connected through the U-shaped frame 10, two sliders 12 are symmetrically arranged on the bidirectional reciprocating lead screw 11, the sliders 12 are slidably connected to the U-shaped frame 10, an L-shaped rod 13 is fixedly connected to the bottom surface of the slider 12, and a guide for driving the gear 6 to rotate is fixedly connected to the end of each L-shaped rod 13;

[0027] The guide includes a Z-shaped plate 9, which is fixedly connected to an L-shaped rod 13. Two racks 8 are fixedly connected to the side of the Z-shaped plate 9. One rack 8 meshes with a gear 6 on the first positioning post 4, and the other rack 8 meshes with a gear 6 on the second positioning post 5. A wheel 14 is fixedly connected to the end of the bidirectional reciprocating screw 11.

[0028] The operation process of this embodiment is as follows: During the positioning process, the rotating wheel 14 drives the bidirectional reciprocating screw 11 to rotate. Since the bidirectional reciprocating screw 11 and the two sliders 12 are threadedly engaged, and the sliders 12 and the U-shaped frame 10 are slidably engaged, rotating the bidirectional reciprocating screw 11 can drive the two sliders 12 to move towards each other. The movement of the sliders 12 drives the L-shaped rod 13 to move. When the L-shaped rod 13 moves, it pushes the Z-shaped plate 9 to move. The movement of the Z-shaped plate 9 drives the two racks 8 on its side to move. When the rack 8 on one of the Z-shaped plates 9 moves, it drives the gears 6 on the first positioning post 4 and the second positioning post 5 to rotate in opposite directions, thereby enabling the first positioning post 4 and the second positioning post 5 to position the sealing body 15 in the perforation. By rotating the turntable, the sealing body 15 can be positioned at multiple points, which speeds up the production and processing efficiency in actual use.

[0029] Example 3

[0030] The first positioning stake 4 and the second positioning stake 5 have a small contact area with the sealing body 15 when positioning it, resulting in a weak positioning effect. The sealing body 15 is prone to displacement during the trimming process. Please refer to [link / reference needed]. Figure 1-3 Based on the first specific embodiment, both the first positioning pile 4 and the second positioning pile 5 are fixedly connected to a positioning block 7 at their ends. The positioning block 7 is used to position the tubular seal and its shape is arc-shaped.

[0031] The operation process of this embodiment is as follows: by setting positioning blocks 7 at the ends of the first positioning stake 4 and the second positioning stake 5, and the positioning blocks 7 are arc-shaped, the contact area of ​​the sealing body 15 can be increased, thereby improving the clamping effect of the sealing body 15 and preventing the sealing body 15 from shifting during the trimming process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
