[0021] like Figure 1-4 and Fig. 9 As shown:

[0022] It includes a fixed seat 201, on which a processing table 101 is rotatably connected, and on which a plurality of clamping rods 102 are slidably connected, and on each clamping rod 102 a cylindrical rod 103 is welded and fixedly connected, and a first compression spring is welded and fixedly connected between each clamping rod 102 and the processing table 101, and a sliding portion 301 is slidably connected to the processing table 101, and a pressing ring 302 is slidably connected to the sliding portion 301, and a plurality of arc-shaped pressing blocks 303 are provided on the pressing ring 302, and a transmission arc-shaped block 304 is provided on the pressing ring 302, and a transmission rod 104 is welded and fixedly connected to the processing table 101, and the transmission rod 104 can contact the transmission arc-shaped block 304, and an arc spring is welded and fixedly connected between the sliding portion 301 and the pressing ring 302, and a first electric push rod is fixedly connected to the processing table 101 by bolts, and the moving end of the first electric push rod is fixedly connected to the sliding portion 301 by bolts.

[0023] The workpiece to be processed is inserted horizontally on the processing table 101, and then the sliding part 301 is operated to slide backward on the processing table 101, thereby driving the pressing ring 302 to slide backward on the processing table 101. During the movement of the pressing ring 302, the transmission arc block 304 will gradually contact the transmission rod 104. Since the transmission arc block 304 is an inclined slope, during the movement of the pressing ring 302, the transmission rod 104 gradually pushes the transmission arc block 304 to make the pressing ring 302 slide on the sliding part 301 by overcoming the elastic force of the arc spring. When the pressing ring 302 slides, the multiple arc pressure blocks 303 will automatically press the multiple cylindrical rods 103, thereby making the multiple clamping rods 102 overcome the elastic force of the first compression spring and slide together, so that the multiple clamping rods 102 clamp the workpiece inserted on the processing table 101 The workpiece is clamped and the clamping effect of the workpiece is completed. Then, during the subsequent processing, the processing table 101 can be operated to rotate on the fixed seat 201, and the clamping angle of the workpiece can be adjusted to provide a suitable angle for the subsequent processing work. That is, in the present application, the clamping operation for the workpiece can be completed by simply sliding the sliding part 301, thereby reducing the possibility of the equipment failing to clamp. It is only necessary to regularly operate and maintain the first electric push rod that drives the sliding part 301 to slide, so as to maintain the stable operation of the equipment. Even if the first electric push rod happens to fail when it is needed, the first electric push rod can be removed by loosening the bolts and the first electric push rod can be repaired or replaced to quickly and conveniently maintain the processing effect, thereby achieving the effect of stably clamping the workpiece and ensuring the stability of the equipment operation.

[0024] like Figure 4 As shown:

[0025] It also includes a fixed frame 401 , a moving part 402 is slidably connected to the fixed frame 401 , a pressing plate 403 is connected to the moving part 402 , and the pressing plate 403 can contact the pressing ring 302 .

[0026] After the sliding part 301 is operated to slide to a suitable distance and the multiple clamping rods 102 are slid to a position where the workpiece can be clamped, the moving part 402 is operated to slide on the fixed frame 401 until the pressing plate 403 abuts against the front side of the pressing ring 302. At this time, the pressing plate 403 can further fix the pressing ring 302 firmly at the position. Therefore, even if the first electric push rod for controlling the movement of the sliding part 301 fails during the subsequent processing, the pressing plate 403 can still limit the pressing ring 302 to a position where the multiple clamping rods 102 can clamp the workpiece, thereby further ensuring the reliability and stability of the operation of the equipment.

[0027] At the same time, when the first electric push rod is found to be faulty and then removed, the moving part 402 can be operated to slide on the fixed frame 401 to drive the pressing plate 403 to move, and then the pressing plate 403 can be used to actively push the pressing ring 302 to slide, thereby achieving the effect of temporarily driving the pressing ring 302 to slide, further ensuring the stable operation of the equipment.

[0028] like Figure 5 As shown:

[0029] It also includes a driving plate 405 slidably connected to the fixed frame 401, and the driving plate 405 can push the moving part 402 to slide. A second compression spring is fixedly connected between the fixed frame 401 and the moving part 402. A first motor is fixedly connected to the fixed frame 401, and a first screw is fixedly connected to the output shaft of the first motor. The first screw is threadedly connected to the driving plate 405.

[0030] When the moving part 402 needs to slide, the moving part 402 can slide by operating the driving plate 405 to slide on the fixed frame 401, thereby driving the pressing plate 403 to move. Under normal circumstances, the moving part 402 is tightly pressed against the driving plate 405 by the elastic force of the second compression spring, which facilitates the subsequent driving work.

[0031] When the first motor and the first electric push rod happen to fail at the same time during the operation of the equipment, and the replacement or repair operation of the first motor and the first electric push rod cannot be completed in a short time, an external power source can be used to directly push the moving part 402 to slide on the fixed frame 401 to complete the clamping effect of the workpiece, thereby further ensuring the stability of the operation of the equipment;

[0032] The external power source can be an electric push rod, a cylinder or other mechanical equipment capable of linear feed. The clamping effect is achieved by pushing the moving part 402. Compared with directly pushing the sliding part 301, it can avoid the main rotating area and prevent the temporary power source from colliding with other parts of the equipment.

[0033] like Figure 4 As shown:

[0034] It also includes an oblique plate 404 fixedly connected to the pressing plate 403. The pressing plate 403 is slidably connected to the moving part 402. The moving part 402 is fixedly connected with a second electric push rod capable of driving the pressing plate 403 to slide.

[0035] When the first motor and the first electric push rod happen to fail at the same time and the replacement or maintenance operation on the first motor and the first electric push rod cannot be completed in a short time, the pressure plate 403 can be operated to slide downward on the moving part 402, and then the inclined plate 404 on the pressure plate 403 can be used to actively press the pressing ring 302, thereby completing the operation of driving the pressing ring 302 to slide. When the second electric push rod also fails to operate, an external power source is used to complete the drive.

[0036] like Figure 6 As shown:

[0037] It also includes a slider 501 connected to the fixed seat 201, the slider 501 is rotatably connected to a matching gear 502, a matching gear ring 105 is fixedly connected to the processing table 101, the matching gear ring 105 is meshed with the matching gear 502, and a second motor that can drive the matching gear 502 to rotate is fixedly connected to the slider 501.

[0038] By starting the second motor to rotate the matching gear 502, the matching gear 502 rotates to drive the matching gear ring 105 to rotate, and then the rotation of the processing table 101 drives the workpiece to rotate, and the workpiece is rotated to a suitable angle to provide support for subsequent processing work.

[0039] like Figure 4 As shown:

[0040] It also includes an auxiliary rod 202 rotatably connected to the fixed seat 201, a third motor is fixedly connected to the fixed seat 201, a transmission gear is fixedly connected to the output shaft of the third motor, a transmission gear ring is fixedly connected to the auxiliary rod 202, and the transmission gear is meshed with the transmission gear ring.

[0041] Before operating the workpiece to rotate, the auxiliary rod 202 can be rotated on the fixed seat 201 first, and the auxiliary rod 202 can be rotated to the target angle required for the subsequent processing table 101 to rotate, and then the processing table 101 can be operated to rotate. After the processing table 101 rotates, the transmission rod 104 on the processing table 101 should be at an angle that can face the auxiliary rod 202, so that the staff can judge whether the program for controlling the rotation angle of the processing table 101 is executed normally by whether the transmission rod 104 can be at an angle that can face the auxiliary rod 202 after the processing table 101 rotates, thereby further ensuring the subsequent workpiece processing effect.

[0042] like Figure 7-8 As shown:

[0043] It also includes a sliding plate 601 slidably connected to the fixed seat 201, the sliding plate 601 is connected to a rotating part 603, the rotating part 603 is fixedly connected to a rectangular block 604, a rectangular groove is opened on the processing table 101, the rectangular block 604 can be inserted into the rectangular groove, the rotating part 603 can rotate around a virtual axis, a second electric push rod that can push the sliding plate 601 to slide is fixedly connected to the fixed seat 201, and the slider 501 is slidably connected to the fixed seat 201, and a third electric push rod that can push the slider 501 to slide is fixedly connected to the fixed seat 201.

[0044] When the second motor fails during the operation of the equipment, causing the processing table 101 to be unable to rotate normally, the operating slider 501 is operated to slide on the fixed seat 201, thereby separating the mating gear 502 from the mating gear ring 105, thereby removing the limiting effect of the second motor on the rotation of the processing table 101, and then the sliding plate 601 is continuously operated to slide on the fixed seat 201, and the rectangular block 604 is inserted into the rectangular groove, and then the rotating part 603 is rotated on the sliding plate 601, and then the rotating rectangular block 604 is used to temporarily drive the processing table 101 to rotate, thereby further ensuring the continuity of the processing.

[0045] As shown in 8:

[0046] It also includes a sliding sleeve 602 slidably connected to the sliding plate 601 , a third compression spring is fixedly connected between the sliding sleeve 602 and the sliding plate 601 , and a fourth motor capable of driving the rotating part 603 to rotate is fixedly connected to the sliding sleeve 602 .

[0047] After the sliding plate 601 is slid to the rectangular block 604 and contacts the processing table 101, the sliding plate 601 can be continuously operated to slide, thereby causing relative sliding between the sleeve 602 and the sliding plate 601. At this time, the third compression spring will gradually deform, thereby providing a forward elastic force to the sleeve 602. At this time, the rotating part 603 can be operated to rotate on the sleeve 602. When the rotating part 603 rotates to an angle at which the rectangular block 604 can be inserted into the rectangular groove, the sleeve 602 will be pulled by the third compression spring and then slide quickly, causing the rectangular block 604 to be inserted into the rectangular groove, thereby facilitating subsequent transmission operations.

[0048] like Figure 5 , Figure 7 and Fig. 9 As shown:

[0049] The fixing seat 201 and the fixing frame 401 are both provided with a plurality of threaded holes.

[0050] The fixing seat 201 and the fixing frame 401 can be fixed by screwing bolts into a plurality of threaded holes, thereby fixing the entire device, which is convenient for subsequent processing operations.

[0051] A machine tool comprises the machine tool rotating tooling.
