Description

Technical Field

[0001] The utility model belongs to the technical field of clamping tooling, in particular to a multifunctional clamping tooling. Background Art

[0002] Bench vises are a common part clamping device used to secure and hold various parts. A typical bench vise consists of a pair of parallel platens, one of which is fixed and the other is driven by a screw, thereby clamping the part. However, this type of bench vise can only be used to clamp plate-shaped or block-shaped parts. It is less effective for cylindrical parts and can easily cause them to deflect, affecting positioning and processing. Utility Model Content

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a multifunctional clamping tool that can be used for clamping plates and cylindrical parts, can effectively prevent the cylindrical parts from deflecting, and has a more stable clamping effect.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A multifunctional clamping tool comprises: a pair of clamping assemblies including mounting seats, wherein the distance between the clamping assemblies is adjustable;

[0006] A U-shaped plate is provided on each opposite side of the mounting seat, and a pressure plate is rotatably provided at the ends of the two side plates of the U-shaped plate, and the rotation axis of the pressure plate is consistent with the extension direction of the cross section of the U-shaped plate;

[0007] When the pressure plates are perpendicular to the side plates of the U-shaped plate, the front end surfaces of the two pressure plates on the same U-shaped plate are in the same plane. A support plate is provided inside the U-shaped plate for supporting the opposite ends of the two pressure plates on the same U-shaped plate. The support plate is movable in a direction perpendicular to the bottom surface of the U-shaped plate.

[0008] The beneficial effect of the present invention is that the present invention utilizes two pairs of pressure plates on two sets of clamping assemblies to form two relatively arranged V-shaped structures to press the surface of the cylindrical part, which can effectively improve the clamping stability of the cylindrical part and prevent the part from shifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present invention.

[0010] Figure 1 Shown is a schematic diagram of the overall structure of this application.

[0011] Figure 2 A schematic structural diagram of the clamping assembly is shown.

[0012] Figure 3 A schematic diagram of a preferred embodiment of the present application is shown.

[0013] Markings in the figure: mounting base-1, positioning pin-11, U-shaped plate-2, spring-21, pressure plate-3, support plate-4, screw-41, base plate-5, slide rail-51, screw-52. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] like Figure 1 、 Figure 2 As shown, a multifunctional clamping tool includes: a pair of clamping components, which include a mounting seat 1, and the distance between the clamping components is adjustable.

[0016] A U-shaped plate 2 is provided on opposite sides of the mounting base 1 , and a pressure plate 3 is rotatably provided at the ends of the two side plates of the U-shaped plate 2 , and the rotation axis of the pressure plate 3 is consistent with the extension direction of the cross section of the U-shaped plate 2 .

[0017] When the pressing plates 3 are perpendicular to the side plates of the U-shaped plate 2, the front end surfaces of the two pressing plates 3 on the same U-shaped plate 2 are in the same plane. A support plate 4 is provided in the U-shaped plate 2 for supporting the opposite ends of the two pressing plates 3 on the same U-shaped plate 2. The support plate 4 is movable in a direction perpendicular to the bottom surface of the U-shaped plate 2 so that when the front end surfaces of the two pressing plates 3 are in a V-shaped structure or are in the same plane, the opposite ends of the two pressing plates 3 can be supported to fix the position of the two pressing plates 3.

[0018] When clamping a flat or block-shaped part, the above structure utilizes the four pressure plates 3 of the two clamping assemblies to simultaneously press against opposite sides of the part. The four pressure plates 3 are in planar contact with the part, allowing the pressure plates 3 to press steadily against the surface of the part even without the support of the support plate 4. When clamping a cylindrical part, the support plate 4 is moved toward the bottom of the U-shaped plate 2 to a predetermined position, allowing the opposing ends of the two pressure plates 3 on the same U-shaped plate 2 to swing toward the support plate 4, thereby satisfying the requirement that the front faces of the two pressure plates 3 form a V-shaped structure. During clamping, the cylindrical part is placed between the two clamping assemblies, with the axis of the part parallel to the axis of rotation of the pressure plates 3. At least one of the clamping assemblies is then moved closer together. This allows the two pairs of pressure plates 3 on the two clamping assemblies to form two oppositely disposed V-shaped structures that press against the surface of the cylindrical part. This method effectively improves the clamping stability of cylindrical parts and prevents them from shifting.

[0019] Preferably, Figure 2 As shown, a wire rod 41 is vertically passed through the bottom plate of the U-shaped plate 2, and the support plate 4 is arranged at the front end of the wire rod 41. By rotating the wire rod 41, the position between the support plate 4 and the bottom plate of the U-shaped plate 2 can be adjusted to control the opening angle of the V-shaped structure formed by the pressure plate 3, so as to adapt to cylindrical parts with different outer diameters. At the same time, the pressure plate 3 can also be supported when the front end surfaces of the two pressure plates 3 are in the same plane. In this way, when clamping small plates or block parts, only one pair of pressure plates 3 in the two sets of clamping assemblies is required to press the parts.

[0020] Preferably, Figure 2 As shown, the opposite ends of the two pressure plates 3 on the same set of U-shaped plates 2 are connected to the bottom plate of the U-shaped plate 2 through a spring 21. When the spring 21 is in a natural state, the pressure plate 3 is perpendicular to the side plate of the U-shaped plate 2. When used to clamp cylindrical parts, the spring 21 is in a compressed state.

[0021] Preferably, the U-shaped plate 2 is rotatably mounted on the mounting base 1 through the bottom plate, and the axis of rotation is perpendicular to the bottom plate of the U-shaped plate 2. A positioning pin 11 is provided between the mounting base 1 and the U-shaped plate 2 for fixing the U-shaped plate 2. Figure 1 、 Figure 3 As shown, the above design can adjust the angle between the part and the horizontal plane, especially the angle between the cylindrical part and the horizontal plane in the clamping state, so that it has different processing postures.

[0022] Preferably, Figure 1 、 Figure 3 As shown, two groups of clamping components are arranged on a base plate 5, one of which is connected to the base plate 5 by screws. A slide rail 51 is provided on the base plate 5 along the connecting direction between the two clamping components. The mounting seat 1 of the other group of clamping components is slidably arranged on the slide rail 51, and the base plate 5 is provided with a screw 52 parallel to the slide rail 51, which is used to drive the mounting seat 1 provided on the slide rail 51, so as to achieve the purpose of adjusting the distance between the two groups of clamping components.

[0023] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
