[0026] A turning and milling composite processing fixture, such as Figure 1-5 As shown, it includes: an operating table 100, a groove 110, a mounting block 120, a rotating block 130, a support frame 140, a bar through hole 150, a slide rail 160, a slider 170, a clamping block 180, a translation assembly 200, a driving assembly 300, an auxiliary clamping assembly 400 and a disassembly assembly 500; the groove 110 is opened on the operating table 100; the mounting block 120 is limitedly slidably connected to the groove 110; the rotating block 130 is rotatably connected to the mounting block 120; the support frame 140 is movably connected to the rotating block 130; at least two bar through holes 150 are opened in the support frame 140; the number of the slide rails 160 is the same as the number of the bar through holes 150 The number is consistent, and the slide rail 160 is fixedly connected to the support frame 140; the number of sliders 170 is consistent with the number of slide rails 160, and the slider 170 is slidably connected to the slide rail 160; the number of clamping blocks 180 is consistent with the number of sliders 170, and the clamping blocks 180 are fixedly connected to the sliders 170; the translation assembly 200 is arranged between the groove 110 and the mounting block 120; the driving assembly 300 is arranged in the support frame 140, and the driving assembly 300 is arranged in cooperation with the slider 170; the number of multiple auxiliary clamping assemblies 400 are all arranged on the clamping block 180; the disassembly assembly 500 is arranged between the rotating block 130 and the support frame 140.

[0027] Specifically, a mounting block 120 is provided on one side of the operating table 100, and a rotating block 130 is rotatably connected to the mounting block 120, a support frame 140 is inserted into the rotating block 130, and a bar through hole 150 is provided on the support frame 140, each of which is slidably connected with a slider 170, and a clamping block 180 is fixedly connected to each slider 170. When the workpiece to be clamped is placed between multiple clamping blocks 180, the driving component 300 is used to drive the multiple clamping blocks 180 to move toward the center of the support frame 140, and then the workpiece is clamped. By setting the translation component 200, the mounting block 120 can be pushed to move in the horizontal direction to increase the processing position of the workpiece; by setting the auxiliary clamping component 400, it is convenient to clamp irregular workpieces and increase the adaptability of the device; by setting the disassembly component 500, it is convenient to repair and replace the support frame 140 and the translation component 200 and the driving component 300 thereon.

[0028] In the embodiment of the present utility model, Figure 1-5 As shown, the translation assembly 200 includes: a motor 210 and a threaded rod 220; the motor 210 is fixedly connected to the operating table 100; the threaded rod 220 passes through the groove 110, and the threaded rod 220 is transmission-connected to the motor 210, and the mounting block 120 is threadedly connected to the threaded rod 220.

[0029] Specifically, the starting motor 210 drives the threaded rod 220 to rotate. By driving the motor 210 to rotate forward, the mounting block 120 is driven to move horizontally to the right. By driving the motor 210 to rotate reversely, the mounting block 120 is driven to move horizontally to the left. The movement of the mounting block 120 drives the driving assembly 300 and the auxiliary clamping assembly 400 thereon to move horizontally, thereby increasing the processing position of the workpiece.

[0030] In the embodiment of the present utility model, Figure 1-5As shown, the driving assembly 300 includes: a cylinder 310, a first U-shaped block 320, a first rotating shaft 330, a moving plate 340, a second U-shaped block 350, a second rotating shaft 360 and a hinge plate 370; the cylinder 310 is fixedly connected to the inner wall of the support frame 140; the number of the first U-shaped blocks 320 is consistent with the number of the sliders 170, and the first U-shaped blocks 320 are fixedly connected to the sliders 170; the number of the first rotating shaft 330 is consistent with the number of the first U-shaped blocks 320, and the first rotating shaft 330 is fixedly passed through the first U-shaped block 320; the moving plate 340, the second U-shaped block 350, the second rotating shaft 360 and the hinge plate 370; the cylinder 310 is fixedly connected to the inner wall of the support frame 140; the number of the first U-shaped blocks 320 is consistent with the number of the sliders 170, and the first U-shaped blocks 320 are fixedly passed through the first U-shaped blocks 320; The movable plate 340 is fixedly connected to the output end of the cylinder 310; the number of the second U-shaped blocks 350 is consistent with the number of the first U-shaped blocks 320, and the second U-shaped blocks 350 are fixedly connected to the movable plate 340; the number of the second rotating shafts 360 is consistent with the number of the second U-shaped blocks 350, and the second rotating shafts 360 are fixedly passed through the second U-shaped blocks 350; the number of the hinged plates 370 is consistent with the number of the second U-shaped blocks 350, and one end of the hinged plate 370 is hinged to the first rotating shaft 330, and the other end of the hinged plate 370 is hinged to the second rotating shaft 360.

[0031] Specifically, when it is necessary to clamp the workpiece, the workpiece is placed on the support frame 140, and the cylinder 310 is started to push the movable plate 340 to move toward the mounting block 120, thereby driving the second U-shaped block 350 fixedly connected thereto to move downward. A hinged plate 370 is hinged at the other end of the second U-shaped block 350, and the other end of the hinged plate 370 is connected to the first U-shaped block 320. The first U-shaped block 320 is connected to the slider 170. Since the clamping block 180 is fixedly connected to the slider 170, when the movable plate 340 moves downward, it drives multiple sliders 170 to move along the slide rail 160 toward the center direction of the support frame 140. Therefore, it drives multiple clamping blocks 180 to move simultaneously in the center direction of the support frame 140, thereby clamping the workpiece.

[0032] In the embodiments of the present invention, Figure 1-5 As shown, the auxiliary clamping assembly 400 includes: a movable groove 410, a movable rod 420 and a spring 430; the movable groove 410 is opened on the clamping block 180; the movable rod 420 is slidably connected to the movable groove 410; one end of the spring 430 abuts against the inner wall of the movable groove 410, and the other end of the spring 430 abuts against the movable rod 420.

[0033] Specifically, a plurality of movable grooves 410 are provided on each clamping block 180, and a movable rod 420 is slidably connected in each movable groove 410. When the workpiece is clamped, the workpiece presses against the plurality of movable rods 420, and each movable rod 420 individually squeezes the corresponding spring 430. Under the elastic force of the spring 430, each movable rod 420 presses against the workpiece. Therefore, the contact points between the workpiece and the clamping block 180 are increased. Especially in the case of irregular parts, each movable rod 420 cooperates with the corresponding spring 430 individually to increase the contact points between the clamping block 180 and the irregular workpiece, thereby avoiding too few contact points and insufficient clamping force. The workpiece may be displaced or fall off, resulting in the processed product not meeting the standards and requiring reprocessing, which wastes both time and raw materials.

[0034] In the embodiments of the present invention, Figure 1-5 As shown, the disassembly assembly 500 includes: a mounting hole 510, a mounting ring 520, a fixing hole 530, a threaded hole 540 and a fastening bolt 550; the mounting hole 510 is opened on the rotating block 130; the mounting ring 520 is fixedly sleeved on the support frame 140; multiple fixing holes 530 are all opened on the mounting ring 520; the number of threaded holes 540 is consistent with the number of fixing holes 530, and the threaded holes 540 are opened on the rotating block 130; the number of fastening bolts 550 is consistent with that of the threaded holes 540, and the fastening bolts 550 are arranged in coordination with the fixing holes 530 and the threaded holes 540. Specifically, when the clamp needs to be cleaned or repaired after being used for a long time, loosen the fastening bolt 550 so that the fastening bolt 550 is disengaged from the threaded hole 540, and then the mounting ring 520 and the mounting hole 510 can be separated, and then the support frame 140 can be taken out from the mounting hole 510, so that the support frame 140 and the clamp thereon can be cleaned or replaced; when installation is required, insert the support frame 140 into the mounting hole 510, and align each fixing hole 530 with the threaded hole 540, screw the fastening bolt 550 therein, and then fix the support frame 140 and the clamp thereon.

[0035] Specifically, a rubber pad is pasted on the side of the moving rod 420 away from the clamping block 180, thereby increasing the friction between the workpiece and the moving rod 420, thereby increasing the clamping force of the moving rod 420 and further strengthening the clamping force; a rubber pad is pasted on the part of the support frame 140 inserted into the rotating block 130, thereby increasing the friction between the support frame 140 and the rotating block 130, increasing its stability, and further avoiding displacement of the support frame 140 during the rotation process.

[0036] In the embodiments of the present invention, Figure 1-5 As shown, a curved rubber pad is attached to the side of the clamping block 180 away from the moving rod 420 .

[0037] Specifically, an arc-shaped rubber pad is pasted on the side of the clamping block 180 away from the moving rod 420. When the surface of the hollow steel pipe needs to be processed, the pipe can be put on the outside of multiple clamping blocks 180. The arc-shaped rubber pad increases its adaptability and also increases the friction of the inner wall of the pipe, further preventing it from falling off.

[0038] In the embodiments of the present invention, Figure 1-5 As shown, it also includes: a rotating device, which is arranged in the mounting block 120 and is transmission-connected to the rotating block 130 .

[0039] Specifically, the rotating device is used to drive the rotating block 130 to rotate.

[0040] It should be noted that the specific models and specifications of the motor 210, the cylinder 310 and the rotating device need to be selected and determined according to the actual specifications of the device, so they will not be described in detail.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
