Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a multi-angle clamping tool for metal processing. Background Art

[0002] In this technical field, the rigidity of metal materials refers to the degree to which metal materials are easily deformed after being subjected to external forces. Before the rigidity test of metal materials, in order to ensure the dimensional accuracy of metal materials and eliminate surface defects of materials, it is usually necessary to cut, grind and other processing of metals to facilitate subsequent inspection and processing. Therefore, clamping tools are needed to clamp and fix the metal materials;

[0003] Most of the existing clamping devices for metal processing are fixed and do not have the function of multi-angle adjustment. They cannot be adjusted according to the user's processing angle requirements, which brings great inconvenience to the user.

[0004] The existing patent (Announcement No.: CN215920262U) discloses a multi-angle adjustable clamping device for metal processing, including a base, a hemispherical sleeve, a fixed clamping plate, a placement plate, a ball pin, a guide block, a movable clamping plate, a first threaded rod, a threaded sleeve, a rotating disk, a fixed plate and other structures. The multi-angle adjustment function is achieved by setting multiple transmission structures, which is convenient for users to adjust the angle of metal parts at any time according to processing requirements;

[0005] Although the existing patent can achieve angle adjustment, it adopts a ball head rotating structure, and the top of the ball pin also supports a clamping mechanism for clamping the workpiece. The clamping mechanism and the workpiece both have a certain weight. When the hemispherical sleeve is separated from the ball pin, it is necessary to support the clamping mechanism and the workpiece by hand while adjusting the angle of the supporting clamping mechanism and the workpiece, and then position the ball pin through the hemispherical sleeve, and the palm cannot remain completely still. Therefore, when supporting the clamping mechanism and the workpiece, the angle of the clamping mechanism and the workpiece will inevitably change. Therefore, the existing technology cannot adjust the angle of the clamping mechanism and the workpiece more accurately. Utility Model Content

[0057] In the description of the present invention, "multiple" means two or more than two, unless otherwise specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a bolt connection or a welding connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] For more precise clamping of metal workpieces, see Figures 1 to 7 The embodiment of the utility model shown provides a multi-angle clamping tool for metal processing.

[0059] In one embodiment, the multi-angle clamping tool provided by the utility model includes a base body 3, a plane rotation mechanism 2, and an angle adjustment mechanism 1, wherein the plane rotation mechanism 2 is below the base body 3 and drives the base body 3 to rotate, the angle adjustment mechanism 1 is arranged below the plane rotation mechanism 2 and adjusts the angle between the plane rotation mechanism 2 and the horizontal plane, and the base body 3 includes a first clamping portion 301 for fixing a metal workpiece with a flat or curved surface, and a second clamping portion 302 for quickly fixing a cylindrical metal workpiece.

[0060] Specifically, when the angle adjustment mechanism 1 adjusts the angle between the plane rotation mechanism 2 and the horizontal plane, since the plane rotation mechanism 2 is connected to the base body 3, the angle between the base body 3 and the horizontal plane is also adjusted at the same time. When the angle changes, the base body 3 tilts on the horizontal plane. At this time, the metal workpiece clamped by the first clamping part 301 or the second clamping part 302 can be processed more conveniently.

[0061] In one specific embodiment, see Figure 1 , Figure 2 and Figure 3 The plane rotation mechanism 2 includes a first turbine 201 and a first worm 202, wherein the first turbine 201 is mounted at the lower end of the seat body 3. Specifically, the first turbine 201 is fixedly connected to the lower end of the center of the seat body 3, and the first worm 202 cooperates with the first turbine 201 to drive the seat body 3 to rotate in the horizontal plane, so that the seat body 3 rotates in the horizontal plane. When in use, the first worm 202 is first rotated to drive the first turbine 201 to rotate, so that the seat body 3 fixed to the first worm 202 rotates. The rotation of the seat body 3 simultaneously drives the first clamping part 301 and the second clamping part 302 located on the seat body 3 to rotate. Then, after the metal workpiece is mounted on the first clamping part 301 or the second clamping part 302, the angle between the metal workpiece and the horizontal plane is adjusted by the angle adjustment mechanism 1, and then the metal workpiece is started to be processed.

[0062] Based on the above embodiments, see Figure 1 , Figure 2 and Figure 3 The plane rotation mechanism 2 of this embodiment includes a fixed seat 203 and a mounting groove 204. The fixed seat 203 is in contact with the lower edge of the seat body 3. The mounting groove 204 passes through the upper and lower surfaces of the fixed seat 203 and accommodates the first turbine 201. The first worm 202 is rotatably connected to the inside of the fixed seat 203 and meshes with the first turbine 201.

[0063] Based on the above embodiments, see Figure 1 and Figure 4The angle adjustment mechanism 1 of this embodiment includes a slide 101, a turbine groove 102, a dovetail guide block 103, a base 104, and a second worm 105. The slide 101 is fixedly connected to the lower end of the fixed seat 203, the turbine groove 102 is arranged at the lower end of the slide 101, and the slide 101 has arc-shaped surfaces on both sides of the turbine groove 102. The dovetail guide block 103 is slidably connected in the turbine groove 102. The base 104 and the dovetail guide block 103 are integrally formed and fit with the arc surface at the lower end of the slide 101. The second worm 105 is screwed inside the dovetail guide block 103 and meshes with the turbine groove 102 and drives the slide 101 to move along the arc-shaped fitting surface between the slide 101 and the base 104. Specifically, since the second worm 105 meshes with the turbine groove 102, the second worm 105 drives the slide 101 to rotate in one direction. The table 101 moves along the arc-shaped fitting surface between the slide 101 and the base 104. It should be noted that the lowest point of the arc-shaped surface on the lower surface of the slide 101 is in the middle of the arc-shaped surface. Therefore, the fixed seat 203 fixed to the slide 101 moves at the same time at this time, and its moving trajectory is consistent with the bending direction of the arc-shaped surface. Therefore, the seat body 3 connected to the fixed seat 203 moves along the trajectory at the same time, so that the angle between the seat body 3 and the horizontal plane changes, and the angle between the first clamping part 301 and the second clamping part 302 and the horizontal plane changes, so that the angle between the metal workpiece fixed on the first clamping part 301 or the second clamping part 302 and the horizontal plane changes, which facilitates the processing of the metal workpiece, and when the second worm 105 is rotated in another direction, the slide 101 is reset.

[0064] Based on the above embodiments, see Figure 1 and Figure 4 The angle adjustment mechanism 1 of this embodiment also includes a positioning bolt 106 that passes through the side of the slide 101 and extends from the turbine groove 102 into the inside of the dovetail guide block 103. In this embodiment, when the positioning bolt 106 extends into the inside of the dovetail guide block 103, the slide 101 is fixed with the dovetail guide block 103, so that after the second worm 104 rotates, the angle between the metal workpiece and the horizontal plane is fixed, providing a holding force, so that the slide 101 can no longer slide, thereby achieving the positioning of the slide 101.

[0065] In one embodiment, see Figure 1 A slide groove 303 is provided around the upper surface of the seat body 3, and a plurality of first clamping parts 301 slide in the slide groove 303. In the present embodiment, two first clamping parts 301 are provided and are arranged relatively in the slide groove 303. In other embodiments, four first clamping parts 301 are provided and are respectively arranged around the upper surface of the seat body 3 and are located in the slide groove 303.

[0066] In the above embodiments, see Figure 1 and Figure 5The first clamping portion 301 includes a slider 304, a stud 305, a support seat 306, a nut 307, an adjustment seat 308, a positioning pin 309, a screw 320, and a clamp seat 310. The slider 304 is slidably connected in the slide groove 303. The stud 305 and the support seat 306 are fixedly connected to the slider 304 on the side away from the angle adjustment mechanism 1. The nut 307 is screwed on the stud 305 and generates a locking force to limit the slider 304. The adjustment seat 308 is connected to the support seat 306 and the slider 304 on the side away from the slider. The adjustment seat 308 is provided with a plurality of slots 319 for accommodating the positioning pin 309. The positioning pin 309 is inserted into the slot 319 and extends into the support seat 306. The screw 320 is screwed laterally inside the adjustment seat 308. The clamp seat 310 is rotatably connected to the screw 320. Specifically, By tightening the nut 307 on the stud 305, the slider 304 can be prevented from sliding in the slide groove 303, and the position of the slider 304 in the slide groove 303 is limited. The screw rod 320 is rotated to drive the clamp seat 310 to move. When two first clamping parts 301 are arranged relatively, the two screw rods 320 are rotated respectively to drive the two clamp seats 310 to approach to clamp the metal workpiece. In addition, when the shape of the metal workpiece is irregular, the positioning pin 309 is pulled out from the slot 319, the adjustment seat 308 is rotated, the positioning pin 309 is inserted into the remaining slots 319 and extends into the support seat 306, and the clamping direction of the clamp seat 310 is adjusted so that the clamp seat 310 can better contact with the outer surface of the irregular-shaped metal workpiece with a larger area, thereby achieving effective and stable clamping. In other embodiments, the outer surface of the clamp seat 310 can be set to a plane or an arc surface to meet the clamping function of metal workpieces of different shapes.

[0067] Based on the above embodiments, see Figure 1 and Figure 5 In this embodiment, a card slot is opened on one side of the outer surface of the clamp seat 310, and the first clamping part 301 also includes a clamping block 311 plugged into the card slot. The side of the clamping block 311 facing away from the clamp seat 310 can be set to a flat surface or an arc-shaped surface. For example, when the metal workpiece is a cylinder, the clamping block 311 is replaced with one with a curved surface on one side, and the clamping block 311 is brought into contact with the metal workpiece by rotating the screw 320 to clamp and fix the cylindrical metal workpiece; when the metal workpiece is a rectangular parallelepiped or a cube, the clamping block 311 is replaced with one with a flat surface on one side, and the screw 320 is rotated to make the clamping block 311 contact with the outer surface of the regular metal workpiece to achieve clamping and fixing. Since the clamping block 311 is clamped in the clamp seat 310, the shape of the clamping block 311 that matches the shape of the clamped metal workpiece can be selected, and then the clamping block 311 is installed in the clamp seat 310 to achieve a better clamping effect.

[0068] In one embodiment, see Figure 6 and Figure 7The second clamping portion 302 includes a groove 312, a plurality of slide grooves 313, and a clamping block 314. The groove 312 is opened inside the seat body 3, the slide groove 313 is opened on the inner wall of the groove 312, the slide groove 313 extends horizontally into the seat body 3, and the plurality of slide grooves 313 are evenly arranged on the inner wall of the groove 312. The clamping block 314 moves back and forth in the slide groove 313. Specifically, the groove 312 is circular and is arranged at the center of the seat body 3. When a cylindrical metal workpiece needs to be clamped quickly, the clamping block 314 moves inside the slide groove 313 toward the center point of the groove 312, similar to a shutter structure, so that the clamping block 314 can quickly clamp the metal workpiece.

[0069] Based on the above embodiments, see Figure 6 and Figure 7 In this embodiment, the second clamping portion 302 further includes a second turbine 315, a guide groove 316, a guide post 317, and a third worm 318. The second turbine 315 is rotatably connected to the inside of the seat body 3 and is located below the slide groove 313. The guide groove 316 is arc-shaped and is opened on the upper surface of the second turbine 315 and communicates with the slide groove 313. The guide post 317 is slidably inserted in the guide groove 316 and is fixedly connected to the clamping block 314. One end of the third worm 318 extends to the outside of the seat body 3 and the other end extends into the inside of the seat body 3 and connects to the second turbine. The wheel 315 meshes and drives the guide column 317 to move back and forth in the guide groove 316. Specifically, the third worm 318 is rotated to rotate the second turbine 315. When the second turbine 315 rotates, the guide groove 316 also rotates. At the same time, since the guide groove 316 is in an arc shape, the guide column 317 is driven to move in the guide groove 316, and the clamping block 314 is driven to move, so that the clamping block 314 can quickly clamp the metal workpiece. When the workpiece needs to be released, it is only necessary to reverse the second turbine 315.
