Technical Field

[0001] The utility model belongs to the technical field of air filtration, and particularly relates to an automatic clamping fixture. Background Technique

[0002] During the processing of workpieces, clamping devices are often required to clamp the workpieces. However, under the demand of mass production, the efficiency of traditional manual clamping is too low and it occupies too much labor, making the demand for automatic clamping increase. To solve the above problems, an automatic clamping fixture is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic clamping fixture to solve the problem that during the processing of workpieces, clamping devices are often required to clamp the workpieces, but under the demand of mass production, the efficiency of traditional manual clamping is too low and it occupies too much labor, making the demand for automatic clamping increase.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is an automatic clamping fixture, including a base, a collet body and a workpiece. A number of mounting screws are connected between the base and the collet body. A cylinder is fixedly installed inside the base. The output end of the cylinder is fixedly connected with a collet screw. A number of collets are hinged on the circumferential side of the inner wall of the collet body. A number of support blocks are fixedly installed inside the collet body. The upper end of the collet screw is hinged with the collet body.

[0006] Among them, both the collet body and the base are in threaded cooperation with the mounting screws, and the workpiece is installed inside the collet body.

[0007] The utility model has the following beneficial effects:

[0008] 1. Through optimized design, on the basis of traditional manual locking application, the utility model designs an automatic clamping mechanism to realize automatic clamping, without the need for manual operation with a wrench, providing the possibility for automatic clamping of parts, reducing the use of labor and improving the practicability of the device.

[0009] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages at the same time. Description of the Drawings

[0010] To more clearly illustrate the technical solutions of the embodiments of the present utility model, the following will briefly introduce the drawings required for describing the embodiments. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0012] Figure 2 It is Figure 1 the schematic structural diagram of the A-A cross-section of

[0013] In the drawings, the list of components represented by each label is as follows: 1. Base; 2. Jacket body; 3. Jacket; 4. Jacket screw; 5. Workpiece; 6. Cylinder; 7. Support block; 8. Mounting screw. Specific embodiments

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0015] Please refer to Figure 1 - Figure 2 As shown, the present utility model is an automatic clamping fixture, including a base 1, a jacket body 2 and a workpiece 5. A plurality of mounting screws 8 are connected between the base 1 and the jacket body 2. A cylinder 6 is fixedly installed in the base 1. The output end of the cylinder 6 is fixedly connected to a jacket screw 4. A plurality of jackets 3 are hinged to the circumferential side of the inner wall of the jacket body 2. A plurality of support blocks 7 are fixedly installed in the jacket body 2. The upper end of the jacket screw 4 is hinged to the jacket body 2. By setting the cylinder 6, the jacket screw 4, the jacket body 2 and the jacket 3, during use: supply air source to the cylinder 6, the piston movement of the cylinder 6 drives the jacket screw 4 to move downward. After the jacket 3 is pulled by the jacket screw 4, due to the restriction of the hinge with the jacket body 2, it can only perform a contraction movement. After contraction, the processed product is clamped.

[0016] Among them, both the jacket body 2 and the base 1 are in threaded cooperation with the mounting screw 8. The workpiece 5 is installed in the jacket body 2. By setting that both the jacket body 2 and the base 1 are in threaded cooperation with the mounting screw 8, it is convenient to connect and fix the jacket body 2 and the base 1.

[0017] Embodiment:

[0018] Such as Figure 1 - Figure 2As shown in the figure, the usage method of an automatic clamping fixture of the present utility model is as follows: When using the present utility model, first place the workpiece 5 to be processed in the chuck body 2. The support block 7 is located below the workpiece 5 to support the workpiece 5. During use: Provide air source for the air cylinder 6. The piston movement of the air cylinder 6 drives the chuck screw 4 to move downward, and then the electric chuck 3 moves. After the chuck 3 is pulled by the chuck screw 4, due to the restriction of being hinged to the chuck body 2, it can only perform a contraction movement. After contraction, the workpiece 5 is clamped, and then the workpiece 5 can be processed.

[0019] The preferred embodiments of the present utility model disclosed above are only used to help explain the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, according to the content of this specification, many modifications and changes can be made.
