[0027] The embodiment of the present application provides a multi-axis reversing fixture, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0028] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Example 1

[0030] See also Figure 1-6 In the embodiment, a multi-axis reversing fixture is provided, comprising: a base plate 1, an adjusting block 2 is connected to the top of the base plate 1, a mounting block 3 is provided on the top of the adjusting block 2, a reversing groove 301 with a fan-shaped structure is opened on the top of the mounting block 3, and a clamping block 4 is rotatably connected to the inside of the reversing groove 301 through a bearing; a rotating component arranged between the reversing groove 301 and the clamping block 4, which is used to change the orientation of the upper clamping block 4, and the rotating component comprises: a rotating groove 302, a rotating rod 303, a gear 304 and a guide groove 6; and a moving component arranged between the mounting block 3 and the adjusting block 2, which is used to change the position of the mounting block 3, and the moving component comprises: a first threaded rod 202, a second threaded rod 205, an adjusting groove 201 and a moving block 305.

[0031] Among them, through the setting of the moving component, the position of the clamping block 4 can be adjusted laterally according to the position of the workpiece that needs to be clamped, without the need to disassemble the clamp and install the clamp to a new position, thereby improving the applicability of the clamp; secondly, in conjunction with the setting of the rotating component, the orientation of the clamping block 4 can be changed according to the clamping position of the workpiece, thereby changing the clamping angle of the workpiece, so that the clamp can fit well to the surface of the clamped workpiece when clamping a special-shaped workpiece.

[0032] Example 2

[0033] On the basis of Example 1, two symmetrically arranged adjustment grooves 201 are opened on the top of the adjustment block 2, four moving blocks 305 are connected to the bottom of the mounting block 3, and the two moving blocks 305 on the same side slide in one of the adjustment grooves 201, and the cross-sectional contour of the moving block 305 matches the cross-sectional size of the adjustment groove 201, and the first threaded rod 202 and the second threaded rod 205 are rotatably connected inside the two adjustment grooves 201 through bearings.

[0034] Among them, a transmission cavity 204 is opened inside the adjusting block 2, and one end of the first threaded rod 202 passes through the transmission cavity 204 and protrudes from the outer surface of the adjusting block 2, and is connected to a handwheel 203, one end of the second threaded rod 205 extends into the transmission cavity 204 and is connected to its inner wall through a bearing, a transmission belt 206 is arranged between the first threaded rod 202 and the second threaded rod 205, and a threaded hole 306 matching the first threaded rod 202 and the second threaded rod 205 is opened on the moving block 305, and the first threaded rod 202 and the second threaded rod 205 are both threadedly connected to the threaded hole 306.

[0035] When clamping and fixing the workpiece, it is necessary to adjust the position of the clamp according to the position of the workpiece and the processing position, so that when the workpiece is processed, the clamp can effectively fix the workpiece to avoid loosening during the processing of the workpiece. At this time, the handwheel 203 can be turned to make the handwheel 203 drive the first threaded rod 202 to rotate, and the first threaded rod 202 drives the second threaded rod 205 to rotate through the transmission belt 206, so that the first threaded rod 202 and the second threaded rod 205 rotate synchronously in the same direction, and the first threaded rod 202 and the second threaded rod 205 are both threadedly engaged with the moving block 305 through the threaded hole 306, so that during the rotation of the first threaded rod 202 and the second threaded rod 205, the moving block 3 is driven to move, thereby changing the position of the clamping block 4 to adapt to the clamping and fixing of different positions of the workpiece.

[0036] Example 3

[0037] On the basis of Example 1, a rotating groove 302 communicating with the reversing groove 301 is opened inside the mounting block 3, and a rotating rod 303 is rotatably connected to the rotating groove 302 through a bearing, and the top of the rotating rod 303 protrudes from the upper surface of the mounting block 3, and a gear 304 is connected to the outside of the rotating rod 303, and the gear 304 is partially located in the reversing groove 301. One side of the clamping block 4 is arranged in an arc shape and is provided with matching teeth meshing with the gear 304. A guide groove 6 communicating with the reversing groove 301 is opened inside the mounting block 3, and the guide groove 6 is an arc structure, and the cross-section of the guide groove 6 is a T-shaped structure. A slider 602 is provided inside the guide groove 6, and a connecting rod 601 is connected to the top of the slider 602, and the top of the connecting rod 601 is connected to the clamping block 4.

[0038] When clamping a special-shaped workpiece, since the existing clamp has a fixed angle, it is impossible to adjust the clamping angle according to the shape of the workpiece. The direction of the clamp block 4 can be changed so that the clamping plate 503 on the clamp block 4 can effectively clamp and fix the workpiece. At this time, by rotating the rotating rod 303, the rotating rod 303 drives the gear 304 to rotate. Since the gear 304 is meshed with the clamp block 4 through the matching teeth 401, the clamp block 4 is driven to rotate during the rotation of the gear 304, so that the clamp block 4 rotates in the reversing groove 301, thereby changing the direction of the clamp block 4, and then changing the clamping angle of the clamping plate 503.

[0039] During the movement of the clamp block 4, the guide groove 6, the connecting rod 601 and the slider 602 are arranged to limit the rotation direction and distance of the clamp block 4. By adjusting the position and orientation of the clamp block 4, the multi-axis reversing effect of the clamp can be achieved.

[0040] Furthermore, a clamping groove 5 is provided on the top of the clamping block 4, and a rotating motor 501 is installed inside the clamping block 4. One side of the rotating motor 501 is driven and connected to a screw rod 502. One end of the screw rod 502 extends into the clamping groove 5 and is connected to the inner wall of the clamping groove 5 through a bearing. The screw rod 502 is provided with two sections of threads in opposite directions. The outer side of the screw rod 502 is threadedly connected to two clamping plates 503 with a T-shaped structure, and the clamping plates 503 protrude from the upper surface of the clamping block 4.

[0041] After adjusting the position and clamping angle of the clamping block 4, the workpiece can be placed on the clamping block 4, and the screw rod 502 can be driven to rotate by the rotating motor 501, and the screw rod 502 drives the two clamping plates 503 to move through the thread. Since the two clamping plates 503 are respectively located on the two sections of the thread of the screw rod 502, the clamping plates 503 can move toward the workpiece at the same time, thereby clamping and fixing the workpiece. Since the cross-sectional profile of the clamping plate 503 matches the cross-sectional size of the clamping groove 5, the moving direction of the clamping plate 503 is limited by the clamping groove 5 during the movement of the clamping plate 503.
