Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a universal tooling fixture with a quick-change positioning module. Background Technology

[0002] A bench vise (also known as a bench clamp) is a general-purpose tooling fixture mainly used for clamping and fixing workpieces for machining. Its advantage lies in its flexibility in adapting to workpieces of various shapes and sizes, without the need for special customization.

[0003] However, existing vises use multiple fixing bolts to assemble the positioning module. Replacement requires disassembling each bolt individually, replacing the module, and then reinstalling the bolts. This repeated assembly and disassembly process is inefficient and cannot meet the demands of modern production for rapid module replacement. Utility Model Content

[0004] Therefore, it is necessary to provide a general-purpose tooling fixture with a quick-change positioning module to address the problem of low replacement efficiency of existing general-purpose tooling fixtures.

[0005] A universal tooling fixture with a quick-change positioning module includes: a clamp body and two positioning fixtures. The top of the clamp body is provided with a threaded transmission mechanism, a fixed clamp seat and a movable clamp seat. The top of both the fixed clamp seat and the movable clamp seat is provided with a mounting groove.

[0006] In one embodiment, the positioning fixture includes a plug inserted into the mounting groove. The vertical cross-sectional shape of the plug is an inverted L-shape. A positioning plate is fixedly connected to the lower surface of the plug between a fixed clamp and a movable clamp. The vertical cross-sectional shape formed by the plug and the positioning plate is n-shaped.

[0007] In one embodiment, both the fixed clamp and the movable clamp have a positioning groove inside that communicates with the mounting groove. The side end of the insert has a U-shaped cavity that communicates with the positioning groove. A U-shaped positioning block is slidably connected inside the U-shaped cavity. One end of the U-shaped positioning block passes through the U-shaped cavity and engages with the positioning groove. The other end of the U-shaped positioning block passes through the U-shaped cavity and extends above the mounting groove.

[0008] In one embodiment, the U-shaped positioning block is disposed inside the positioning groove and has a vertical cross-sectional shape of a right triangle, with the inclined surface of the U-shaped positioning block facing away from the positioning plate.

[0009] In one embodiment, an adjustment strip is fixedly connected to the other end of the U-shaped positioning block, and the surface of the adjustment strip is rounded.

[0010] In one embodiment, a spring is provided between the adjusting bar and the insert block, and the spring is always in a compressed state.

[0011] In one embodiment, the spring is a rubber material component, the vertical cross-sectional shape of the spring is square, and the spring is sleeved on the surface of the U-shaped positioning block.

[0012] In one embodiment, the adjusting bar and the insert block each have a limiting groove at their opposite ends, and the two ends of the spring pass through the interior of the two limiting grooves respectively.

[0013] In one embodiment, the vertical cross-sectional shapes of the defining groove and the spring are both matching square shapes.

[0014] Beneficial effects The aforementioned universal tooling fixture for quick replacement of positioning modules achieves automatic alignment and quick snap-fit ​​of the positioning module through the contact design between the right-angled triangular cross section of the U-shaped positioning block and the inclined surface of the mounting groove. When the insert block is pressed down, the interaction force of the inclined surfaces causes the U-shaped positioning block to automatically retract into the U-shaped cavity. Disassembly can be completed by pressing the adjustment strip once, without the need for repeated tightening of traditional bolts. The spring is made of rubber and has a square cross-section design. The structure with the limiting grooves embedded at both ends not only restricts the torsional deformation of the spring, but also forms a sealed barrier to prevent debris from entering the U-shaped cavity. This design provides continuous elasticity to enhance the interlocking strength between the U-shaped positioning block and the positioning groove, while avoiding the defect of traditional helical springs being prone to debris jamming.

[0023] The following is combined Figures 1-4 This invention describes a universal tooling fixture with a quick-change positioning module.

[0024] In one embodiment, a universal tooling fixture with a quick-change positioning module includes: a clamp body 100 and two positioning fixtures 600. The top of the clamp body 100 has a sliding cavity, and the top of the clamp body 100 is provided with a threaded transmission mechanism 200. The threaded transmission mechanism 200 includes a threaded sleeve, and a threaded post is threadedly connected to the inner side of the threaded sleeve. One end of the threaded post is rotatably connected to a movable clamp seat 400 that is slidably connected to the sliding cavity. The top of the clamp body 100 is fixedly connected to a fixed clamp seat 300 opposite to the movable clamp seat 400. The other end of the threaded post is fixedly connected to an adjustable throttle. The tops of both the fixed clamp seat 300 and the movable clamp seat 400 have mounting grooves 500.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning fixture 600 includes an insert block 610 inserted into the mounting groove 500. The vertical cross-sectional shape of the insert block 610 is an inverted L-shape. A positioning plate 620 is fixedly connected to the lower surface of the insert block 610 between the fixed clamp seat 300 and the movable clamp seat 400. The vertical cross-sectional shape formed by the insert block 610 and the positioning plate 620 is n-shaped. The fixed clamp seat 300 and the movable clamp seat 400 are both provided with positioning grooves 700 that communicate with the mounting groove 500. The side end of the insert block 610 is provided with a U-shaped cavity 611 that communicates with the positioning groove 700. A U-shaped positioning block 630 is slidably connected inside the U-shaped cavity 611. One end of the U-shaped positioning block 630 passes through the U-shaped cavity 611 and is engaged with the positioning groove 700. The other end of the U-shaped positioning block 630 passes through the U-shaped cavity 611 and extends to the top of the mounting groove 500.

[0026] The U-shaped positioning block 630, located inside the positioning groove 700, has a vertical cross-sectional shape of a right triangle. The inclined surface of the U-shaped positioning block 630 faces away from the positioning plate 620. As the U-shaped positioning block 630 moves down into the mounting groove 500, the inclined angle of the mounting groove 500 contacts the inclined surface of the U-shaped positioning block 630, and the U-shaped positioning block 630 is pressed back into the U-shaped cavity 611 by the mounting groove 500. The user only needs to actively adjust the position of the U-shaped positioning block 630 to complete the installation, thereby speeding up the user's replacement speed. An adjustment strip 640 is fixedly connected to the other end of the U-shaped positioning block 630. The surface of the adjustment strip 640 is rounded, which makes it easy for the user to press and adjust the U-shaped positioning block 630.

[0027] A spring 650 is provided between the adjusting bar 640 and the insert block 610. The spring 650 is always in a compressed state. The spring 650 can not only automatically reset the adjusting bar 640 and the U-shaped positioning block 630 after they are no longer obstructed, but also increase the connection strength between the U-shaped positioning block 630 and the positioning groove 700 when the U-shaped positioning block 630 is inserted into the positioning groove 700, making the positioning plate 620 run more stably.

[0028] Spring 650 is a rubber component with a rectangular vertical cross-section. Spring 650 is fitted onto the surface of U-shaped positioning block 630. The adjusting strip 640 and the insert block 610 each have a limiting groove 660 at their opposite ends. Both ends of spring 650 pass through the interior of the two limiting grooves 660. The vertical cross-sections of limiting grooves 660 and spring 650 are matching rectangular shapes. This not only limits the running trajectory of spring 650 and avoids the probability of spring 650 twisting or deviating, but also prevents processing debris from entering the gap between U-shaped positioning block 630 and U-shaped cavity 611, ensuring that U-shaped positioning block 630 can move normally.

[0029] In this embodiment, the usage process of the vise is as follows: 1. Preparatory steps: Fix the clamp body 100 to the corresponding plane with bolts, and then insert the insert block 610 on the positioning plate 620 that matches the workpiece into the mounting groove 500 until the two positioning plates 620 are installed in the corresponding positions. 2. Workpiece installation: Place the workpiece against the positioning plate 620 that is in contact with the fixed clamp 300 and faces the movable clamp 400. Then, adjust the corresponding rotating threaded rod. The threaded rod drives the movable clamp 400 to slide horizontally along the sliding cavity along the threaded sleeve. The movable clamp 400 drives the positioning plate 620 connected to it to approach the workpiece until the two positioning plates 620 cooperate to clamp the workpiece. 3. Workpiece removal: Rotate the threaded rod in the opposite direction. The threaded rod will drive the movable clamp 400 and the positioning plate 620 connected to it to separate from the workpiece along the threaded sleeve until the distance between the two positioning plates 620 is sufficient to remove the workpiece. Then the workpiece can be easily removed. IV. Replacement of Positioning Plate 620: Press the adjusting bar 640. The adjusting bar 640 will cause the U-shaped positioning block 630 to separate from the positioning groove 700 and retract into the U-shaped cavity 611. Then, the insert block 610 along with the positioning plate 620 can be lifted and removed. Then, repeat the installation operation of the positioning plate 620 in step one to complete the quick replacement.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
