Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing equipment, and in particular relates to an adaptive clamp for irregular automobile radiator parts. Background Art

[0002] When using machine tools to mill and cut automotive radiator parts, fixtures are required to fix the parts being processed. This is done to ensure the fixed operation and to ensure that the parts are fully positioned to ensure processing accuracy. In the normal processing process, in addition to parts with regular shapes such as squares and rectangles, irregular-shaped parts such as circles, ellipses, polygons, or other shapes are often encountered. When processing regular-shaped parts, universal fixtures can be used to complete the fixation. However, when using universal fixtures to clamp irregular-shaped parts, a good clamping effect cannot be achieved. Therefore, the processing of irregular-shaped parts is carried out using special fixtures. This results in the need to design separate fixtures for different irregular-shaped parts, which increases production and processing costs. At the same time, special fixtures cannot be used to process other parts, resulting in a waste of resources. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an adaptive fixture for irregular automobile radiator parts. By providing a movable block and a fixing unit that can fix the movable block, the fixture can adapt to parts of different shapes.

[0004] An adaptive fixture for irregular automobile radiator parts includes a clamping device and a base. The clamping device is used to clamp the part. Two clamping devices are symmetrically mounted on the base, allowing the clamping devices to move closer or further away from each other, thereby clamping the part from both sides. The clamping device includes a sliding base, a clamping unit, and a fixing unit. The clamping unit consists of a movable block, a spring, and a fixed box. The fixed box has an opening at one end. The movable block is mounted within the fixed box through the opening, allowing free movement. The spring is mounted within the fixed box, with the ends of the spring connected to the fixed box and the movable block, respectively, so that the spring's elastic force can act on the movable block. To achieve adaptive function for irregular part shapes, multiple clamping units are mounted on the sliding base and fixed side by side to form a single unit. The fixing units are then mounted on the sliding base, positioned below the movable block, allowing them to fix the position of the movable block. The sliding base is then connected to the base via a first cylinder. The first cylinder propels the sliding base, allowing the two clamping devices to move closer or further away from each other to clamp the part.

[0005] As the specific structure of the fixing unit, the fixing unit consists of a lower clamping block, an upper clamping block and a second cylinder, wherein the lower clamping block is arranged below the movable block, and the upper clamping block is arranged above the movable block. The two ends of the upper clamping block and the lower clamping block are connected by the second cylinder. The upper clamping block can be controlled to move up and down by the extension and contraction of the second cylinder to achieve locking and release of the movable block.

[0006] To ensure the fixture maintains a fixed direction of motion during operation, guide grooves are provided on the upper and lower surfaces of the movable block, and matching guide rails are installed within the fixed box. A sliding rail is installed at the bottom of the sliding seat, and a matching sliding groove is provided on the base. The direction of the guide rail and sliding rail is set to align with the direction of motion of the clamping device. This ensures that the sliding seat and movable block can only move in a fixed direction, ensuring effective clamping.

[0007] Since the outer peripheral shape of irregular parts is not necessarily flat, in order to ensure that the ends of the movable block can adapt to different situations, the irregular parts are clamped, the cross-section of the outer end of the movable block is tapered, and the tip of the tapered edge is chamfered. This structure can ensure that the ends of the movable block can adapt to the outer peripheral shape of irregular parts.

[0008] In order to ensure that the fixing unit can have a better fixing effect on the movable block, the upper and lower end surfaces of the movable block, the upper end surface of the lower clamping block, and the lower end surface of the upper clamping block are treated with anti-slip treatment. The anti-slip treatment can adopt all existing means, including surface roughening, sticking anti-slip glue, setting anti-slip patterns, etc.

[0009] The adaptive clamp for irregular automobile radiator parts provided by the utility model can clamp irregular parts of different shapes, has good clamping and fixing effect, has a simple structure and is easy to operate, can be applied to large-scale production and processing, and effectively reduces the manufacturing cost of the clamp.

DETAILED DESCRIPTION

[0017] To further illustrate the concept of the present invention, the following will further describe the specific implementation of the present invention with reference to the accompanying drawings:

[0018] An adaptive fixture for irregular automobile radiator parts includes a clamping device 2 and a base 1. The clamping device 2 includes a sliding seat 3, a clamping unit 4, and a fixing unit 5. A movable block 6 is made of a long metal block, and a fixing box 8 is made to fit the movable block 6. One end of the movable block 6 is cut into a chamfered cone, and guide grooves 13 are cut on the upper and lower end surfaces of the movable block 6. The upper and lower end surfaces are then roughened. A guide rail 14 is installed at the corresponding position in the fixing box 8. The spring 7 is first installed in the fixing box 8, and then the other end of the movable block 6 is inserted into the fixing box 8 for installation, thereby obtaining a clamping unit 4. Figure 4 、 Figure 5 As shown. Twenty-one clamping units 4 are made and fixed side by side on the sliding seat 3. A lower clamping block 11 is fixed to the position of the sliding seat 3 below the movable block 6. Second cylinders 12 are installed at both ends of the lower clamping block 11. The second cylinder 12 is vertically upward. The two ends of the upper clamping block 10 are connected to the second cylinder 12. Then, the lower end surface of the upper clamping block 10 and the upper end surface of the lower clamping block 11 are roughened to form a fixed unit 5. A sliding rail 15 is installed at the bottom of the sliding seat 3. A sliding groove 16 is opened on the base 1. The direction of the sliding rail 15 is consistent with that of the guide rail 14. The sliding rail 15 is clamped in the sliding groove 16. A first cylinder 9 is installed on the base 1 at the rear part of the sliding seat 3. The first cylinder 9 and the sliding seat 3 are connected to obtain a clamping device 2, as shown. Figure 2 、 Figure 3 As shown. Using the above method, two symmetrical clamping devices 2 are installed on the base 1 to obtain a complete fixture, as shown Figure 1 shown.

[0019] When processing irregular parts, first place the irregular part between the two clamping devices 2 of the base 1, and then start the first cylinder 9 to allow the two clamping devices 2 to move closer to the middle. When the movable block 6 of the clamping unit 4 contacts the side of the irregular part, it is pushed back into the fixed box 8. Since a spring 7 is provided in the fixed box 8, the movable block 6 always fits the side of the irregular part under the action of the spring 7. When all the movable blocks 6 contact the irregular part, a clamping space for the irregular part is naturally formed in the middle of all the movable blocks 6. Stop the first cylinder 9 and start the second cylinder 12 to retract the upper clamping block 10 downward so that the movable block 6 is tightly clamped together by the upper clamping block 10 and the lower clamping block 11. Since the contact surface between the movable block 6 and the upper clamping block 10 and the lower clamping block 11 is rough, it can provide a large friction force to prevent the movable block 6 from moving. Then start the first cylinder 9 again to further clamp the irregular part, and then the milling operation can be carried out.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and variations are possible. Any modifications, equivalent replacements, improvements, etc. made using the present invention should be included in the scope of protection of the present invention.
