[0032] A fixture is a device used to fix and clamp a workpiece during CNC machine tool processing. It can stably fix the workpiece in the required position by adjusting the position and strength of the clamping parts for processing, assembly, testing, etc.

[0033] In the related art, the tightness of the clamp fixing device cannot be controlled well by manual operation, and the workpiece is usually quickly and accurately limited and fixed by electric means before processing. However, sometimes during processing, not only the upper end of the workpiece but also the lower end of the workpiece needs to be processed, so the workpiece needs to be loosened first, then turned over and fixed before processing, which results in cumbersome operation and low work efficiency.

[0034] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a clamp fixing device. When the workpiece needs to be limited, fixed and turned over, it is only necessary to place the workpiece in the center of the surface of the base 11, and then the rotation of the output end of the motor 22 drives the rotation of the threaded rod 23, and the rotation of the threaded rod 23 drives the movement of the connecting block 24 to drive the movement of the clamp 16, thereby fine-tuning the clamp 16 to make the clamp 16 located in the center of the workpiece, and then the rotation of the output end of the motor 12 drives the rotation of the bidirectional screw rod 13, and the rotation of the bidirectional screw rod 13 drives the two sliding bars 14 to move closer to each other, and the movement of the two sliding bars 14 closer to each other drives the two clamps 16 to move closer to each other to limit the workpiece, and then The upper end of the workpiece is processed. When the lower end of the workpiece needs to be processed, the rotation of the output end of the motor 22 drives the threaded rod 23 to rotate, and the rotation of the threaded rod 23 drives the connecting block 24 on the inner wall of the adjusting hole 21 to move up, and the upward movement of the connecting block 24 drives the connecting seat 25, the motor 3 26, the clamping plate 16 and the workpiece to move up into place, thereby avoiding bumping against the surface of the base 11 and being unable to flip during the flipping process. When the workpiece moves up into place, the motor 3 26 drives the connecting block 27 to rotate, and the rotation of the connecting block 27 drives the clamping plate 16 and the workpiece to rotate. When the workpiece is flipped into place, the reverse rotation of the output end of the motor 22 drives the workpiece to move down and place it on the surface of the base 11 for processing of the lower end, thereby facilitating the flipping of the workpiece.

[0035] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0036] Combination Figure 1-Figure 4The embodiment of the present application provides a clamp fixing device, including a clamping assembly 1; the clamping assembly 1 includes: a base 11, on which a motor 12 is arranged; a bidirectional screw rod 13, which is arranged on the output end of the motor 12, and the bidirectional screw rod 13 is rotatably connected to the base 11; a sliding bar 14, which is threadedly connected to the bidirectional screw rod 13; a sliding groove 15, which is opened on the base 11, and the sliding groove 15 is slidably connected to the sliding bar 14; a clamping plate 16, which is arranged on the sliding bar 14; an adjusting assembly 2 is arranged on the sliding bar 14 The adjusting component 2 includes: an adjusting hole 21, which is opened on the sliding bar 14; a second motor 22, which is arranged on the sliding bar 14; a threaded rod 23, which is arranged on the output end of the second motor 22, and the threaded rod 23 and the sliding bar 14 are rotatably connected; a connecting block 24, which is threadedly connected to the threaded rod 23; a connecting seat 25, which is arranged on the connecting block 24; a third motor 26, which is arranged on the connecting seat 25; a connecting block 27, which is arranged on the output end of the third motor 26, and the clamping plate 16 is installed on the connecting block 27.

[0037] A fixture is a device used to fix and clamp a workpiece during machining on a CNC machine tool. It fixes the workpiece stably in the desired position by adjusting the position and strength of the clamping parts, so as to facilitate machining, assembly, testing, etc. Therefore, when the workpiece needs to be fixed and turned over, it is only necessary to place the workpiece in the exact center of the surface of the base 11, and then the rotation of the output end of the motor 22 drives the rotation of the threaded rod 23, and the rotation of the threaded rod 23 drives the movement of the connecting block 24, thereby driving the movement of the clamp 16, thereby fine-tuning the clamp 16 so that the clamp 16 is located in the exact center of the workpiece, and then the rotation of the output end of the motor 12 drives the rotation of the bidirectional screw 13, and the rotation of the bidirectional screw 13 drives the movement of the two sliding bars 14 to move closer to each other, and the movement of the two sliding bars 14 to move the two clamps 16 to move closer to each other to limit the workpiece. The workpiece is fixed in position, and then the upper end of the workpiece is processed. When the lower end of the workpiece needs to be processed, the rotation of the output end of the motor 22 drives the threaded rod 23 to rotate, and the rotation of the threaded rod 23 drives the connecting block 24 of the inner wall of the adjusting hole 21 to move up, and the upward movement of the connecting block 24 drives the connecting seat 25, the motor 3 26, the clamping plate 16 and the workpiece to move up into place, thereby avoiding bumping against the surface of the base 11 and being unable to flip during the flipping process. When the workpiece moves into place, the motor 3 26 drives the connecting block 27 to rotate, and the rotation of the connecting block 27 drives the clamping plate 16 and the workpiece to rotate. When the workpiece is flipped into place, the reverse rotation of the output end of the motor 22 drives the workpiece to move down and place it on the surface of the base 11 for processing of the lower end, thereby facilitating the flipping of the workpiece.

[0038] In some embodiments, a disassembly assembly 3 is provided on the splint 16, and the disassembly assembly 3 includes: a fixing plate 31, which is provided on the splint 16; a screw 32, which is threadedly connected to the fixing plate 31; and a fixing groove 33, which is opened on the connecting block 27, and the screw 32 is inserted into the fixing groove 33.

[0039] When the splint 16 needs to be installed, the splint 16 is fitted together with the connecting block 27. After the splint 16 is fitted into place, the screws 32 are rotated and inserted into the fixing grooves 33 on both sides of the connecting block 27 for fixing. When the splint 16 needs to be removed, the screws 32 are rotated in the opposite direction to disengage from the fixing grooves 33 to release the fixation. Finally, the splint 16 can be removed. In this way, the splint 16 can be easily replaced after being damaged during use.

[0040] In some embodiments, the disassembly assembly 3 also includes: a positioning rod 34, which is arranged on the splint 16; a positioning groove 35, which is opened on the connecting block 27, and the positioning rod 34 is inserted into the positioning groove 35. When the splint 16 needs to be installed, the two positioning rods 34 on one side of the splint 16 are aligned and inserted into the two positioning grooves 35 on one side of the connecting block 27 for positioning, thereby avoiding displacement during the installation process.

[0041] In some embodiments, the disassembly assembly 3 also includes: a guide block 36, which is arranged on the positioning rod 34. When the positioning rod 34 needs to be inserted into the positioning groove 35, because the guide block 36 is conical, it is convenient for the positioning rod 34 to be quickly and accurately inserted into the positioning groove 35.

[0042] In some embodiments, a mounting seat 4 is provided on the base 11. When the fixture device needs to be installed on the workbench of a CNC machine tool for use, the fixture device is fixed by the mounting seat 4 in conjunction with bolts, thereby facilitating installation, fixing and disassembly of the fixture device.

[0043] In some embodiments, an anti-skid pad 5 is provided on one side of the clamping plate 16. When the workpiece is fixed by moving the two clamping plates 16 closer to each other, the anti-skid pad 5 can increase the friction between the clamping plate 16 and the workpiece, making the clamping and fixing of the two clamping plates 16 more stable.

[0044] In some embodiments, the width of the connecting block 24 is equal to the width of the adjusting hole 21. When the connecting block 24 is moved by the rotation of the threaded rod 23, the width of the adjusting hole 21 is equal to the width of the connecting block 24, which can prevent the connecting block 24 from deflecting during the movement.

[0045] In some embodiments, the sliding bar 14 is in a “T” shape, so that the sliding bar 14 can slide more stably on the inner wall of the sliding groove 15 and avoid being separated from the sliding groove 15 .

[0046] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0047] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
