Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seal positioning technology, specifically a positioning tool for cutting automotive seals. Background Technology
[0002] Automotive seals are important components inside automobiles used to prevent and block the leakage of liquids or gases. Because automotive seals need to adapt to various complex shapes and sizes in the automotive structure, they need to be cut and processed to a precision that precisely matches the automotive components.
[0003] Currently, when cutting automotive seals, the user typically places the seal on the outside of a ring-shaped disc and cuts it to the appropriate precision using a cutting tool. Since the size of the disc is fixed, it cannot be positioned correctly when cutting seals that are too large or too small. In this case, it is necessary to replace the disc with one that is about the same size as the seal. If the replacement is too frequent, it will be time-consuming and labor-intensive, resulting in reduced work efficiency. Summary of the Invention
[0004] This utility model provides a positioning fixture for cutting automotive seals. It can drive the positioning blocks to move synchronously towards or away from each other by setting a positioning mechanism, thereby positioning and fixing automotive seals of different sizes, making the cutting blade more stable when cutting automotive seals.
[0005] To achieve the above objectives, a positioning fixture for cutting automotive seals is provided, comprising a mounting base, a positioning mechanism fixedly connected to the upper end of the mounting base, positioning blocks provided at the upper end of the positioning mechanism, the positioning blocks being a plurality of blocks evenly distributed in a ring at equal angles, the positioning mechanism being fixedly connected to the positioning blocks, a rotating seat provided below the mounting base, the bottom surface of the mounting base contacting the upper surface of the rotating seat, a rotating motor fixedly mounted at the center of the inner bottom surface of the rotating seat, the output end of the rotating motor being fixedly connected to the center of the bottom surface of the mounting base, and the rotating... A base is fixedly connected to the bottom surface of the mounting base. A mounting plate is fixedly connected to the upper end of the base on the side away from the mounting base. A pressure cylinder is fixedly installed on the upper end of the mounting plate on the side away from the mounting base. The telescopic end of the pressure cylinder passes through the mounting plate, and a cutting blade is fixedly installed on the telescopic end of the pressure cylinder. The positioning mechanism includes a fixed plate, a sliding groove, a limiting post, an adjusting plate, a limiting block, an adjusting plate, a limiting rod, a rotating post, a limiting plate, and a rotating plate. The fixed plate is fixedly connected to the top surface of the mounting base. The sliding groove is formed on the upper surface of the fixed plate, and there are several sliding grooves corresponding to the positioning blocks. By setting up the mutual cooperation between the positioning mechanism and the positioning blocks, the positioning mechanism can drive the positioning blocks to move synchronously towards or away from each other, positioning and fixing automotive seals of different sizes, making the cutting blade more stable when cutting automotive seals.
[0006] According to the aforementioned positioning fixture for cutting automotive seals, the limiting block is slidably connected to the inner side of the sliding groove, the upper surface of the limiting block is fixedly connected to the bottom surface of the positioning block, and the limiting post is slidably connected to the inner side of the limiting block. Both ends of the limiting post pass through the limiting block and are fixedly connected to the opposite sides of the sliding groove. By setting the limiting post, the limiting block is limited, reducing the problem of the limiting block disengaging from the sliding groove.
[0007] According to the aforementioned positioning fixture for cutting automotive seals, a spring is sleeved on the outer side of the limiting post, and both ends of the spring are fixedly connected to the limiting block and the side of the sliding groove away from the center of the fixed plate, respectively. By setting the interaction between the spring and the limiting block, the spring can push the limiting block towards the center of the fixed plate, facilitating adjustment.
[0008] According to the aforementioned positioning fixture for cutting automotive seals, the adjusting plate is fixedly connected to the lower surface of the limiting block. The side of the adjusting plate near the center of the fixed disk is angled, gradually approaching the center of the fixed disk from top to bottom. The rotating column is rotatably connected to the inner side of the center of the fixed disk, and its bottom end is rotatably connected to the bottom surface of the inner cavity of the mounting base. The lower end of the rotating column is threaded, and the adjusting disk is threadedly connected to it. The outer side of the adjusting disk contacts the angled part of the adjusting plate. The limiting plate is fixedly connected to the bottom surface of the adjusting plate, and the side of the limiting plate near the center of the fixed disk is longer than the adjusting plate. The rotation of the rotating column causes the adjusting disk to move up and down, and with the cooperation of the adjusting disk and the angled part, the adjusting plate moves synchronously towards or away from each other. The limiting plate limits the adjustment plate, preventing it from detaching from the adjusting plate.
[0009] According to the aforementioned positioning fixture for cutting automotive seals, the limiting rod is slidably connected to the inner side of the adjusting plate. Several limiting rods are evenly distributed within the adjusting plate, and both ends of each limiting rod are fixedly connected to the lower surface of the fixed plate and the bottom surface of the inner cavity of the mounting base, respectively. By setting the limiting rods to limit the adjustment plate, the problem of rotation during movement is significantly reduced.
[0010] According to the aforementioned positioning fixture for cutting automotive seals, the rotating disk is fixedly connected to the upper end of the rotating column, and a friction plate is fixedly connected to the bottom surface of the rotating disk. The bottom surface of the friction plate contacts the upper surface of the fixed disk, and the friction plate is made of rubber. By using rubber for the friction plate, the friction force between the friction plate and the rotating disk is increased, reducing the problem of the rotating column rotating during positioning.
[0011] According to the aforementioned positioning fixture for cutting automotive seals, the limiting block engages with the sliding groove, and the contact surface between the limiting block and the sliding groove is made smooth. By making the contact surface between the limiting block and the sliding groove smooth, friction is reduced, allowing the limiting block to move more stably.
[0012] The beneficial effects of this utility model are as follows: by setting up a positioning mechanism, a positioning block and a mounting base to cooperate with each other, the positioning mechanism can drive the positioning block to move synchronously towards or away from each other, thereby positioning and fixing automotive seals of different sizes, making the cutting blade more stable when cutting automotive seals, and eliminating the need to replace the disc, saving time and effort and improving work efficiency.

[0024] A spring is sleeved on the outside of the limiting post 2203, and the two ends of the spring are fixedly connected to the limiting block 2205 and the side of the sliding groove 2202 away from the center of the fixed plate 2201, respectively.

[0029] Working principle: In use, first take out the car seal and compare it with the positioning block 2. If the car seal is found to be too large, rotate the rotating disk 2210, which will drive the rotating column 2208 to rotate. During rotation, the rotating column 2208 will drive the adjusting disk 2206 to move downward through the surface threads. As the adjusting disk 2206 moves downward, it will gradually come into contact with the angled lower side of the adjusting plate 2204. Since the downward angle of the adjusting plate 2204 gradually approaches the center of the fixed disk 2201, the adjusting plate 2204 will drive the limiting block 2205 to gradually move away from the center of the fixed disk 2201. When the limiting block 2205 moves, it will drive the positioning block 2 to move synchronously until it is close to the size of the car seal. After the positioning block 2 is adjusted, the friction plate 9 will limit the rotating disk 2210 by contacting it, thereby reducing the problem of the rotating disk 2210 rotating on its own. Next, the car seal is placed on the outside of the positioning block 2, and the pressure cylinder 5 is started to push the cutting blade 6 to contact the car seal and penetrate one side of the car seal. Then, the rotating motor 4 is started to drive the car seal to rotate, so that the cutting blade 6 can complete the cutting of the car seal in one circle.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
