Description

Technical Field

[0001] This utility model relates to the field of machining tooling and fixture technology, and in particular to a multi-purpose hydraulic chuck. Background Technology

[0002] Traditional hydraulic chucks are inconvenient for clamping parts such as valves, and can easily damage the workpiece surface. Their structure is relatively simple, making it difficult to adapt to the machining needs of different types of parts (such as valves, discs, shafts, and square plates), resulting in poor versatility. When machining valves, the lack of a clamping structure specifically designed for the valve shape easily leads to problems such as valve rotation and displacement during clamping, affecting machining accuracy and efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] To achieve the above objectives, this utility model proposes a multi-purpose hydraulic chuck, including a hydraulic chuck body, the hydraulic chuck body having a soft claw adjustment groove, a soft claw being provided on the soft claw adjustment groove, an arc-shaped clamping groove being provided on the soft claw, and a quick-release soft block being provided on the soft claw.

[0005] Furthermore, a slider is provided inside the soft claw adjustment groove, a soft claw adjustment threaded hole is provided on the slider, a soft claw bolt groove is provided on the soft claw, a soft claw adjustment bolt is provided in the soft claw bolt groove, and the soft claw adjustment bolt is threadedly adapted to the soft claw adjustment threaded hole.

[0006] Furthermore, the side of the hydraulic jaw body that contacts the soft jaw is provided with soft jaw adjustment teeth.

[0007] Furthermore, the soft claw is provided with a soft block bolt groove, and a soft block fixing bolt is provided in the soft block bolt groove. The soft block fixing bolt is threadedly connected to the quick-release soft block.

[0008] Furthermore, both the soft claw and the quick-release soft block are made of soft metal.

[0009] Furthermore, the bottom of the hydraulic chuck body is provided with chuck adjustment teeth that are adapted to the guide rail of the clamp.

[0010] Beneficial effects:

[0011] 1. The quick-release soft block and soft claw of this utility model can effectively prevent damage to the outer surface of the valve, improve the clamping speed, and reduce the impact on the surface roughness of the valve.

[0012] 2. The quick-release soft block can be replaced with a suitable soft block according to different specifications of valves. If the same product is processed again, it can be directly replaced, so as not to waste raw materials.

[0013] 3. The quick-release soft block and soft claw allow for precise adjustment of the clamping position; the soft claw can be used to clamp disc-shaped parts.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The multi-purpose hydraulic chuck of this utility model embodiment will now be described with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the multi-purpose hydraulic chuck provided in this embodiment of the present invention includes a hydraulic chuck body 1, a soft claw adjustment groove 12, a soft claw 2 on the soft claw adjustment groove 12, an arc-shaped clamping groove 21 on the soft claw 2, and a quick-release soft block 3 on the soft claw 2.

[0023] A slider 4 is provided inside the soft claw adjustment groove 12. A soft claw adjustment threaded hole 41 is provided on the slider 4. A soft claw bolt groove 22 is provided on the soft claw 2. A soft claw adjustment bolt 42 is provided in the soft claw bolt groove 22. The soft claw adjustment bolt 42 is threadedly matched with the soft claw adjustment threaded hole 41.

[0024] The hydraulic gripper body 1 and the soft gripper 2 are both equipped with soft gripper adjusting teeth 13 on their contact surfaces. The soft gripper 2 has a soft block bolt groove 23, within which a soft block fixing bolt 31 is installed, threadedly connected to the quick-release soft block 3. Both the soft gripper 2 and the quick-release soft block 3 are made of soft metal. The bottom of the hydraulic gripper body 1 is equipped with gripper adjusting teeth 11 that are compatible with the guide rail 6 of the clamp 5.

[0025] Specifically, this utility model adds an adjustable multi-purpose soft claw 2, a slider 4, and a quick-release soft block 3. The soft claw 2 is connected to the quick-release soft block 3 via a soft block fixing bolt 31. The soft claw 2 is connected to the slider 4 via a soft claw adjusting bolt 42. Both are fixed on the soft claw adjusting teeth 13 of the hydraulic chuck body 1. By loosening the soft claw adjusting bolt 42, the soft claw 2 and the quick-release soft block 3 can be adjusted on the hydraulic chuck body 1. By tightening the soft claw adjusting bolt 42, the soft claw 2 and the quick-release soft block 3 are fixed on the hydraulic chuck body 1. The soft claw 2 and the quick-release soft block 3 can be flexibly adjusted according to the positioning teeth.

[0026] The quick-release soft block 3 can be machined into a suitable shape on a milling machine according to the valve model to solve the clamping and positioning problem. The quick-release soft block 3 can be replaced according to different valve specifications. The soft claw 2 can clamp disc-shaped parts and can be repaired to adapt to products of different diameters. It can also be easily removed to use traditional hydraulic jaws to process other parts, realizing one machine for multiple uses.

[0027] The soft claw 2 and quick-release soft block 3 can be made of copper or other soft metal materials to prevent damage to the product surface.

[0028] To clearly illustrate the above embodiments, refer to Figures 1-3 The working principle of this utility model's multi-purpose hydraulic chuck is as follows: When processing a certain type of valve, first adjust the position of the hydraulic chuck body 1 on the fixture 5 according to the valve size, then place the valve on the clamping point of the quick-release soft block 3. After the quick-release soft block 3 clamps the valve, tighten the soft claw adjusting bolt 42 and perform CNC machining. When processing other valves of different specifications, loosen the soft claw adjusting bolt 42 and replace it with a suitable quick-release soft block 3. The removed quick-release soft block 3 is kept for future use and can be directly replaced when processing the same product again, thus avoiding waste of raw materials.

[0029] When machining disc-shaped parts, the hydraulic jaw body 1 is installed in reverse, and the jaws are adjusted according to the diameter of the disc-shaped parts so that the arc-shaped clamping groove 21 of the soft jaw 2 fits tightly against the parts for machining.

[0030] When machining shaft-type or square plate-type products, remove the soft jaw 2 and use the hydraulic jaw body 1 for normal clamping and machining.

[0031] In summary, this application solves the problems of inconvenience in clamping valves and easy damage to product surfaces caused by traditional hydraulic chucks by adding an adjustable quick-release soft jaw 2 and a quick-release soft block 3 to the traditional hydraulic chuck; improves the versatility of hydraulic chucks for valves of different sizes and various parts such as discs, shafts, and square plates; and enhances processing efficiency and processing accuracy.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
