Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for automobile parts production. Background Technology

[0002] Automotive clamping devices are mainly used to fix workpieces to ensure accuracy and safety during production, processing, or assembly. They can fix workpieces in a specific position to avoid deviations or scratches caused by manual operation. Automated fixtures can also replace manual handling, reducing labor costs.

[0003] In the automotive manufacturing industry, there is a type of fixture called a rotary table specifically designed for machining automotive clutch gear hubs. The characteristic of automotive clutch gear hubs is their varying wall thickness, thus requiring specialized fixtures. However, some fixtures that restrict the size of automotive clutch gear hubs have a fixed limit, while the size of clutch gear hubs may differ between different automobiles. This results in fixtures that can only restrict a single workpiece size having limited versatility. To address this issue, we provide a clamping device for automotive parts production. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a clamping device for automobile parts production, which solves the problem of poor versatility of clamps through the cooperation between components such as pallets and clamps.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for automobile parts production, comprising a base, a limiting plate connected to the upper surface of the base, teeth connected inside the limiting plate, and a protective ring connected to the upper surface of the limiting plate;

[0008] The limiting plate is slidably connected to a tray inside, a clamping plate is slidably connected to the upper surface of the tray, a toothed plate is slidably connected to the inside of the tray, and a spring is connected to the outer surface of the toothed plate.

[0009] A second spring is connected to the bottom surface of the clamping plate, and a limit hole is opened inside the clamping plate. A limit rod is slidably connected to the inner side wall of the limit hole.

[0010] Furthermore, the feature is that a central expansion sleeve is installed on the upper surface of the limiting plate, and a push plate is installed on the central expansion sleeve.

[0011] Furthermore, the outer surface of the tooth is combined with the outer surface of the tooth plate, and one end of the spring away from the tooth plate is connected to the interior of the tray.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this clamping device for automotive parts production has the following advantages:

[0018] I. This clamping device for automotive parts production, through the cooperation between components such as the pallet and the clamp, allows the pallet to move. The number of movable clamps can be adjusted by moving the pallet, allowing workers to move clamps to different positions. Clamps at different positions will match circles of different diameters, allowing the device to adapt to more automotive clutch hubs of different sizes, thereby enhancing the versatility of the clamp and solving the problem of insufficient versatility of clamps.

[0019] II. This clamping device for automotive parts production, through the cooperation between components such as the toothed plate and the limiting rod, prevents the pallet from moving laterally by the meshing of the toothed plate and the teeth, thereby limiting the position of the pallet and ensuring the number of clamps supported by the pallet. The limiting rod can limit the direction of movement of the clamps, allowing the clamps to move only up and down, thus avoiding deviations in the position of the clamps. It is very easy to use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] The central expansion sleeve 12 and cylinder 15 in this utility model are common devices in the prior art, and this application will not elaborate on their models or internal structures.

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a clamping device for automobile parts production, including a base 1, a limiting plate 2 connected to the upper surface of the base 1, teeth 3 connected inside the limiting plate 2, and a protective ring 4 connected to the upper surface of the limiting plate 2. The base 1 restricts the position of the limiting plate 2, preventing the limiting plate 2 from moving, the limiting plate 2 restricts the position of the teeth 3, and the limiting plate 2 restricts the position of the protective ring 4.

[0030] The limiting plate 2 has a tray 5 slidably connected inside, a clamping plate 6 slidably connected to the upper surface of the tray 5, a toothed plate 7 slidably connected inside the tray 5, and a spring 8 connected to the outer surface of the toothed plate 7. The limiting plate 2 restricts the direction in which the tray 5 can move. When the tray 5 moves upward, it can move the clamping plate 6 above it. The clamping plates 6 will not contact each other, and the edge clamping plates 6 will not contact the protective ring 4, thereby avoiding wear on the clamping plates 6. The clamping plates 6 can provide flexible support for the edge position of the workpiece, thereby restricting the edge position of the workpiece. The tray 5 restricts the direction in which the toothed plate 7 can move, and the spring 8 provides a thrust to the toothed plate 7. The edge of the toothed plate 7 is provided with a plate that can move it. The user can move the position of the toothed plate 7 by moving this plate.

[0031] A spring 9 is connected to the bottom surface of the clamping plate 6. A limit hole 10 is opened inside the clamping plate 6. A limit rod 11 is slidably connected to the inner side wall of the limit hole 10. The spring 9 will provide tension to the clamping plate 6. When the clamping plate 6 moves open, the spring 9 will pull the clamping plate 6 down. The limit rod 11 will restrict the direction of movement of the clamping plate 6 through the limit hole 10, so that the clamping plate 6 can only move up and down.

[0032] A central expansion sleeve 12 is installed on the upper surface of the limiting plate 2. A push plate 13 is installed on the central expansion sleeve 12. The central expansion sleeve 12 can provide air pressure to the push plate 13, allowing the push plate 13 to move out of the central expansion sleeve 12 and allowing the push plate 13 to tighten the workpiece.

[0033] The outer surface of the tooth 3 engages with the outer surface of the toothed plate 7. The end of the spring 8 away from the toothed plate 7 is connected to the inside of the tray 5. After the tooth 3 engages with the toothed plate 7, the toothed plate 7 can no longer move laterally, thus limiting the position of the toothed plate 7. This allows the user to accurately adjust the lateral position of the toothed plate 7, thereby accurately controlling the number of upward-moving clamps 6. The tray 5 will limit the position of the spring 8.

[0034] The tray 5 has an internal support column 14. The outer surface of the support column 14 is slidably connected to the inside of the toothed plate 7. The spring 8 is sleeved on the outer surface of the support column 14. The tray 5 restricts the position of the support column 14. The support column 14 can prevent the spring 8 from bulging to one side when compressed.

[0035] A cylinder 15 is installed on the bottom surface of the limiting plate 2. The output end of the cylinder 15 contacts the bottom surface of the tray 5. The tray 5 moves up and down by starting the cylinder 15, and the movement of the tray 5 moves the clamping plate 6.

[0036] The bottom surface of spring 29 is connected to the upper surface of the limiting plate 2, and the bottom surface of the limiting rod 11 is connected to the upper surface of the limiting plate 2. Spring 29 is sleeved on the outer surface of the limiting rod 11. The limiting plate 2 restricts the position of spring 29 and the limiting rod 11. The limiting rod 11 can prevent spring 29 from bulging to one side when compressed.

[0037] The upper surface of the tray 5 contacts the bottom surface of the protective ring 4, and one end of the tray 5 contacts the outer surface of the central expansion sleeve 12. The protective ring 4 restricts the tray 5 from moving upward to the highest position, and the central expansion sleeve 12 restricts the position where the tray 5 can move laterally.

[0038] Working principle: When using, first, the workpiece needs to be placed on the central expansion sleeve 12, and the central expansion sleeve 12 is activated to make the push plate 13 tighten the workpiece. Then, the user needs to move the toothed plate 7 to separate it from the teeth 3. Then, the pallet 5 is moved to a position that can block the edge of the workpiece clamping plate 6. Then, the toothed plate 7 is released, and the spring 8 pushes the toothed plate 7 to engage with the teeth 3. Then, the user can activate the cylinder 15. The cylinder 15 will make the pallet 5 move upward with the clamping plate 6, so that the clamping plate 6 blocks the edge of the workpiece, and the workpiece can be processed.

[0039] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
