Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for processing metal products. Background Technology

[0002] Fixtures are devices used in machining, manufacturing, and other fields to fix workpieces. They determine the workpiece position through positioning elements and then secure it with clamping devices, thereby ensuring machining accuracy, improving efficiency, and ensuring operational safety. They come in a variety of types, including general-purpose fixtures suitable for various workpieces (such as vises and chucks), special-purpose fixtures for specific workpieces, and flexible combination fixtures, and are widely used in turning, milling, welding, assembly, and other processes.

[0003] However, most current fixtures have obvious limitations: most can only fix the workpiece in a single direction. If different surfaces or angles of the workpiece need to be processed during the machining process, the workpiece must be disassembled, adjusted and re-clamped. This not only increases the operation time, but may also lead to increased machining errors due to repeated positioning. Especially in complex processes that require multi-face machining, it will significantly affect machining efficiency and accuracy stability. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-8 This utility model provides a fixture for processing metal products, comprising: a base 100, a first support 110, a second support 120, a rotating device, and a clamping device. The first support 110 and the second support 120 are disposed opposite each other on the top surface of the base 100. The clamping device is rotatably mounted on the side of the first support 110 and the second support 120 that are close to each other. The rotating device is mounted on the side of the first support 110 away from the clamping device, and the rotating device is used to drive the clamping device to rotate. In other embodiments, the rotating device may be mounted on the second support 120, or the rotating device may be mounted on both the first support 110 and the second support 120.

[0021] The rotating device includes a rotating shaft, a worm gear 310, a worm 320, and a housing 300. The housing 300 is fixedly connected to the side of the first support 110 away from the clamping device. The rotating shaft is rotatably connected to the first support 110. One end of the rotating shaft is fixedly connected to the worm gear 310, and the other end is fixedly connected to the connecting seat 200. The worm 320 cooperates with the worm gear 310. Both ends of the worm 320 are rotatably connected to the housing 300. One end of the worm 320 passes through the housing 300 and is connected to a third handwheel (not shown in the figure).

[0022] The worm gear 320 can be easily rotated via the third handwheel. The rotation of the worm gear 320 drives the worm wheel 310, which in turn drives the rotating shaft, which in turn drives the connecting seat 200. Once the workpiece is clamped, the rotating device drives the connecting seat 200 on one side to rotate, and the connecting seat 200 on the other side will follow suit. After one side of the workpiece is machined, the worm gear 320 can be rotated to move the workpiece to the next machining surface or angle. The entire process does not require disassembling the workpiece, greatly improving machining efficiency.

[0023] The clamping device includes a connecting seat 200, a fixed clamping block 210, a movable clamping block 220, and a first moving device. The connecting seat 200 is rotatably connected to the first bracket 110 and the second bracket 120. The fixed clamping block 210 and the movable clamping block 220 are arranged opposite to each other on the side of the two connecting seats 200 that are close to each other. The fixed clamping block 210 is fixedly connected to the connecting seat 200. The movable clamping block 220 is movably installed on the connecting seat 200. The connecting seat 200 has a first mounting groove 201. The first moving device is installed in the first mounting groove 201. The first moving device drives the movable clamping block 220 to move closer to or away from the fixed clamping block 210.

[0024] The first moving device is a lead screw and slider mechanism. Specifically, the first moving device includes a first lead screw 400 and a first slider 410. The first lead screw 400 is parallel to the length direction of the first mounting groove 201. Both ends of the first lead screw 400 are rotatably connected to the side wall of the first mounting groove 201, and one end of the first lead screw 400 passes through the side wall of the first mounting groove 201 to reach the outside of the connecting seat 200. A first handwheel (not shown in the figure) is connected to the end of the first lead screw 400 extending to the outside of the connecting seat 200. The first slider 410 is threadedly connected to the first lead screw 400. This can be achieved by directly opening a threaded hole on the slider or welding a nut onto the slider. The first slider 410 is slidably connected to the first mounting groove 201. The first slider 410 is fixedly connected to the moving clamp 220. The first slider 410 is welded to the moving clamp 220 or the first slider 410 and the moving clamp 220 are integrated.

[0025] The first handwheel is fixedly connected to the first lead screw 400. Rotating the first handwheel drives the first lead screw 400 to rotate, which in turn drives the first slider 410 to move along the length of the lead screw. The movable clamping block 220 is welded to the first slider 410. When the movable clamping block 220 moves closer to the fixed clamping block 210, it clamps the workpiece; when the movable clamping block 220 moves away from the fixed clamping block 210, it releases the workpiece.

[0026] like Figure 8 The first mounting groove 201 has a first opening on the side near the movable clamping block 220. The width 'a' of the first opening is smaller than the width 'b' inside the first mounting groove 201. In this embodiment, the cross-section of the first mounting groove 201 is convex, and the first slider 410 is also convex. The first slider 410 cooperates with the first mounting groove 201 to prevent the first lead screw 400 from driving the first slider 410 to rotate during rotation. Of course, the cross-section of the first mounting groove 201 can also be set to other shapes, such as dovetail, as long as the first lead screw 400 is prevented from driving the first slider 410 to rotate.

[0027] The fixture for metal product processing also includes a second moving device, which is used to adjust the distance between the first support 110 and the second support 120, thereby enabling the fixture to clamp workpieces of different lengths and improving its applicability. The base 100 has a second mounting groove 101, and the second moving device is installed in the second mounting groove 101. The first support 110 is fixedly connected to the base 100, and the second support 120 is connected to the second moving device. The second moving device drives the second support 120 to move closer to or further away from the first support 110.

[0028] The second moving device is a screw-slider mechanism. Specifically, the second moving device includes a second screw 500 and a second slider 510. The second screw 500 is parallel to the length direction of the second mounting groove 101. Both ends of the second screw 500 are rotatably connected to the side wall of the second mounting groove 101, and one end of the second screw 500 passes through the side wall of the second mounting groove 101 to reach the outside of the base 100. A second handwheel (not shown in the figure) is connected to the end of the second screw 500 extending outside the base 100. The second slider 510 is threadedly connected to the second screw 500, slidably connected to the second mounting groove 101, and fixedly connected to the second bracket 120. The second slider 510 and the second bracket 120 are either welded together or the second slider 510 and the second bracket 120 are integral.

[0029] The second handwheel is fixedly connected to the second lead screw 500. Rotating the second handwheel drives the second lead screw 500 to rotate, which in turn drives the second slider 510 to move along the length of the lead screw. The second bracket 120 is welded to the second slider 510. When the second bracket 120 approaches the first bracket 110, it clamps the workpiece; when the second bracket 120 moves away from the first bracket 110, it releases the workpiece.

[0030] like Figure 7 The second mounting groove 101 has second openings on both sides near the movable clamping block 220. The width m of the second opening is smaller than the width n inside the second mounting groove 101. In this embodiment, the cross-section of the second mounting groove 101 is convex, and the second slider 510 is also convex. The second slider 510 cooperates with the second mounting groove 101 to prevent the second lead screw 500 from driving the second slider 510 to rotate during rotation. Of course, the cross-section of the second mounting groove 101 can also be set to other shapes, such as dovetail, as long as the second lead screw 500 is prevented from driving the second slider 510 to rotate.

[0031] like Figures 8-10 The fixture for metal product processing also includes a V-shaped clamping block 600, which is detachably mounted on the movable clamping block 220 and the fixed clamping block 210. The V-shaped clamping block 600 can easily clamp cylindrical workpieces, further improving the fixture's applicability. Of course, the replaceable clamping block is not limited to the V-shaped clamping block 600; clamping blocks of different shapes can also be customized according to the workpiece shape for replacement. The V-shaped clamping block 600 can be magnetically attached to the movable clamping block 220 and the fixed clamping block 210 or fixed with bolts and nuts. In this embodiment, mounting holes 211 are provided on both the movable clamping block 220 and the fixed clamping block 210, and mounting holes 211 are also provided on the V-shaped clamping block 600, allowing for installation using bolts and nuts.

[0032] The upper parts of the first support 110 and the second support 120 are semi-circular. A cylindrical scale portion 202 is provided on the side of each connecting seat 200 that is far apart from the other. Angle information is engraved on the circumference of the scale portion 202. Markers 111 indicating the initial position are engraved on the first support 110 and the second support 120. The scale portion 202 allows for a direct view of the current workpiece rotation angle. When machining a workpiece at a specific angle is required, the scale portion 202 allows for quick rotation of the workpiece to that angle.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
