Description

Technical Field

[0001] This application relates to the field of horizontal machine tool technology, and in particular to a horizontal machining center for the production of multi-size workpieces. Background Technology

[0002] Horizontal machining equipment is a CNC machine tool with a horizontal spindle as its core. Its horizontal spindle layout, combined with the multi-directional movement of the worktable, can efficiently complete milling, drilling, boring and other processes. It is especially suitable for machining large box-shaped, rotating workpieces and complex curved surfaces. The equipment has a high rigidity structure to ensure stability under heavy cutting.

[0003] A prior art patent with utility model publication number CN219945300U discloses a deep hole machining fixture for a horizontal machining center. In this prior art patent, the workpiece is clamped and fixed by two clamping plates to complete the workpiece installation. However, in this prior art patent, the clamping plates are only suitable for clamping workpieces of a specific diameter. When the diameter of the workpiece changes, the clamping device cannot be used to clamp the workpiece, resulting in inconvenience for installing workpieces of different radii on the horizontal machining center. Utility Model Content

[0004] To address the problem that clamping devices cannot be used to clamp workpieces of different diameters, which leads to inconvenience in workpiece installation on horizontal machining centers, this application provides a horizontal machining center for the production of multi-size workpieces.

[0005] This application provides a horizontal machining center for producing multi-size workpieces, employing the following technical solution:

[0006] A horizontal machining center for producing multi-size workpieces includes a horizontal machining device and a tooling table. Two sets of clamping fixtures are arranged opposite each other on the tooling table. Each set of clamping fixtures includes an arrangement component, a clamping mounting component, and a feed component. The arrangement component has several clamping plates, each with a clamping groove of radius R. The radii R of the clamping grooves are not equal. The feed component can transfer the corresponding clamping plate to the clamping mounting component. The clamping mounting component can adjust the clamping position of the clamping plate on the workpiece. Clamping plates of equal radius on the two clamping mounting components are arranged opposite each other. The tooling table has a fastening component connected to the two sets of clamping fixtures. The fastening component can drive the two sets of clamping fixtures to move relative to each other, so that the two clamping plates clamp and fix the workpiece.

[0007] By adopting the above technical solution, when installing a workpiece onto a horizontal machining center, the workpiece is placed on the tooling table. Then, the feed assembly, based on the workpiece's radius, transfers the clamping plate corresponding to the clamping slot from the arrangement assembly to the clamping and mounting assembly. The clamping and mounting assembly then adjusts the clamping height of the clamping plate according to the workpiece. Finally, the fastening assembly drives the two sets of clamping fixtures closer together. At this point, the two clamping plates clamp and fix the workpiece, completing the installation and positioning of the workpiece on the horizontal machining center. By setting clamping plates with clamping slots of different radii, compared to the prior art which can only clamp and fix workpieces of one radius, this application can select clamping plates of corresponding radii to clamp and fix the workpiece according to its different radii, thereby improving the flexibility of clamping and fixing workpieces and the convenience of clamping and fixing workpieces of different radii.

[0008] Preferably, the arrangement assembly includes an arrangement plate with multiple placement cavities. The multiple placement cavities are spaced apart along the vertical direction. Each placement cavity corresponds to a clamping plate, and the clamping plate can be completely placed inside the placement cavity.

[0009] By adopting the above technical solution, multiple placement cavities are arranged at intervals along the vertical direction on the arrangement plate, so that each clamping plate can be placed in a corresponding manner. This facilitates the orderly storage of clamping plates with clamping slots of different radii, avoids mutual interference, and protects the clamping plates from external collision damage. It also provides convenience for quickly selecting a suitable clamping plate according to the workpiece radius.

[0010] Preferably, the clamping and mounting assembly includes a linear drive mechanism, an upper clamping plate, and a lower clamping plate. The linear drive mechanism is disposed on the arrangement plate, and the lower clamping plate is connected to the linear drive mechanism and located on opposite sides of the two arrangement plates. The linear drive mechanism can drive the lower clamping plate to slide up and down. The feeding assembly can drive the clamping plate to slide onto the lower clamping plate so that the clamping groove is fully exposed. The upper clamping plate is connected to the upper clamping plate through a pressing element so that the upper clamping plate can be driven to press and fix the clamping plate on the lower clamping plate.

[0011] By adopting the above technical solution, the linear drive mechanism can drive the lower clamping plate to slide up and down to adjust the clamping position of the clamping plate on the workpiece. The feed component can make the clamping plate slide onto the lower clamping plate to fully expose the clamping groove, which is convenient for accurately clamping the workpiece. The pressing component can drive the upper clamping plate to press and fix the clamping plate on the lower clamping plate, ensuring that the clamping plate is installed firmly, thereby improving the reliability and accuracy of clamping and fixing the workpiece.

[0012] Preferably, the pressure generating element includes a first electromagnet and a second electromagnet. The first electromagnet is fixedly disposed on the lower clamping plate, and the second electromagnet is fixedly disposed on the upper clamping plate. The first electromagnet and the second electromagnet are arranged opposite to each other and both can generate positive and negative magnetic fields.

[0013] By adopting the above technical solution, positive and negative magnetic fields are generated by the first electromagnet and the second electromagnet, which can flexibly control the clamping and loosening of the upper clamping plate on the clamping plate. It is convenient to quickly replace clamping plates of different radii to meet the clamping requirements of workpieces of various sizes, and improve the convenience of clamping operation of horizontal machining center in the processing of workpieces of various sizes.

[0014] Preferably, each of the placement cavities has a first guide groove on its bottom wall, and the lower clamping plate has a second guide groove that is opposite to the first guide groove. Each clamping plate has a guide block that can slide within the first guide groove and the second guide groove. The end of the second guide groove has a positioning surface that can restrict the movement of the clamping plate.

[0015] By adopting the above technical solution, the first guide groove and the second guide groove guide the guide block, which can make the clamping plate slide accurately onto the lower clamping plate. At the same time, the positioning surface can accurately define the position of the clamping plate, thereby improving the accuracy and stability of the clamping plate installation and positioning.

[0016] Preferably, a blocking part is fixedly provided on the upper clamping plate, and the blocking part can abut against the clamping plate to form support for the clamping plate.

[0017] By adopting the above technical solution, the shielding part provides support for the clamping plate, making the clamping plate more stable during operation and further improving the reliability of workpiece clamping and fixing.

[0018] Preferably, the feeding assembly corresponds one-to-one with the clamping plate. The feeding assembly includes a rotary hydraulic cylinder and a lever. The rotary hydraulic cylinder is disposed on the arrangement plate and connected to the lever so as to drive the lever to push the clamping plate to slide onto the lower clamping plate.

[0019] By adopting the above technical solution, using the feeding components that correspond one-to-one with the clamping plates, the rotating hydraulic cylinder drives the lever to push the clamping plates, which can accurately transfer the clamping plates with the corresponding radius clamping slots to the lower clamping plate, thus improving the accuracy and efficiency of selecting the appropriate clamping plates.

[0020] Preferably, the lever includes a lever body and a third electromagnet. The lever body is connected to the rotary hydraulic cylinder. The third electromagnet is fixedly disposed at the end of the lever body and can attract the clamping plate. The lever body can pull the clamping plate back to the placement cavity.

[0021] By adopting the above technical solution, the third electromagnet is set on the rod body, which can attract the clamping plate on the lower clamping plate and reset it into the placement cavity. This makes it convenient to select a suitable clamping plate for the next use, realize the convenient storage and recycling of the clamping plate, and improve the continuity and efficiency of the horizontal machining center operation.

[0022] Preferably, the fastening assembly includes a drive screw and a drive motor. The drive motor is connected to the tooling table. The drive screw is coaxially fixed with the output shaft of the drive motor and passes through the two sets of arrangement plates. The drive screw has two threaded sections with opposite directions. The threaded sections correspond one-to-one with the arrangement plates and are threadedly connected to the arrangement plates.

[0023] By adopting the above technical solution, the drive motor drives the drive screw to rotate. By using the two threaded sections on the screw with opposite directions of rotation to connect with the threaded sections of the arrangement plate, the two sets of arrangement plates can be driven to move relative to each other in a precise and stable manner, so as to realize the reliable clamping and fixing of the workpiece by the two clamping plates that are set opposite to each other.

[0024] Preferably, the horizontal machining device includes a spindle head, an XZ-axis moving frame, and a YA-axis drive frame. The XZ-axis moving frame is connected to the spindle head to drive the spindle head to move along the X and Z axes. The YA-axis drive frame is connected to the tooling table to drive the tooling table to move along the Y axis and rotate along the A axis.

[0025] By adopting the above technical solution, the X-Z axis moving frame drives the spindle head to move along the X and Z axes, and the Y-A axis moving frame drives the tooling table to move along the Y axis and rotate along the A axis, which enables the horizontal machining center to operate flexibly in multiple directions and increases the range and accuracy of machining workpieces of multiple sizes.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Based on the workpiece radius, the feeding component can select the clamping plate with the corresponding radius clamping slot and transfer it to the clamping and mounting component, which improves the flexibility of workpiece installation and positioning;

[0038] The following will be combined with the appendix Figures 1-7 The technical solutions in the embodiments of the present invention are further described in detail below. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Those skilled in the art can certainly combine the embodiments of the present invention to obtain other embodiments without creative effort, which are also within the protection scope of the present invention.

[0039] This application mainly adopts a scheme of setting multiple radius clamping slots 61 and corresponding clamping plates 6 to flexibly adapt to the workpiece, which achieves the effect of improving the convenience of horizontal machining center for clamping workpieces of different radii. The following is a further detailed description of this application.

[0040] Reference Figure 1 , Figure 2 A horizontal machining center for producing multi-size workpieces includes a horizontal machining device 2 and a fixture table 3. Two sets of clamping fixtures 4 are arranged opposite each other on the fixture table 3. Each set of clamping fixtures 4 includes an arrangement component 41, a clamping and mounting component 42, and a feed component 43. A fastening component 5 connected to the two sets of clamping fixtures 4 is provided on the fixture table 3. The fastening component 5 can drive the two sets of clamping fixtures 4 to move relative to each other, thereby achieving workpiece clamping. The arrangement component 41, clamping and mounting component 42, and feed component 43 cooperate sequentially to prepare for clamping workpieces of different radii. This cooperation allows the entire horizontal machining center to flexibly adjust the clamping components according to the different radii of the workpieces, improving the convenience of clamping and fixing workpieces of different radii.

[0041] Reference Figure 1 In this embodiment, the horizontal machining device 2 includes a spindle head 21, an XZ-axis moving frame 22, and a YA-axis driving frame 23. The XZ-axis moving frame 22 includes an X-axis moving frame 221 and a Z-axis moving frame 222. The YA-axis driving frame 23 includes a Y-axis moving frame 231 and an A-axis rotating frame 232. The X-axis moving frame 221, the Y-axis moving frame 231, and the Z-axis moving frame 222 all use a screw-nut structure and a linear guide-slider structure to achieve linear sliding. The Z-axis moving frame 222 is connected to the base 1. The X-axis moving frame 221 is mounted on the Z-axis moving frame 222. The spindle head 21 is mounted on the X-axis moving frame 221. The movements of the X-axis moving frame 221 and the Z-axis moving frame 222 work together on the spindle head 21 to achieve the movement of the spindle head 21 along the X and Z directions.

[0042] Reference Figure 1 Because of the large amount of chips falling and accumulating in the horizontal machining center, the chips fall onto the Z-axis guard and slide down to the base, causing chip accumulation that is not easy to clean. Therefore, chip removal grooves 24 are provided on both sides of the Z-axis sliding frame of the base 1, so that the chips fall directly into the chip removal grooves 24, improving the convenience of chip removal.

[0043] Reference Figure 1To reduce the impact of debris entering the X-axis moving frame 221 on the lead screw-nut structure, telescopic folding plates 25 are provided on both sides of the slide inside the X-axis moving frame 221. When the X-axis moving frame 221 drives the spindle head 21 to slide along the X-axis, the telescopic folding plate 25 on one side of the slide unfolds, and the telescopic folding plate 25 on the other side retracts to accommodate the movement of the spindle head 21. At the same time, the debris is folded, effectively avoiding the impact of debris on the lead screw-nut structure inside the X-axis moving frame 221.

[0044] Reference Figure 1 The spindle head 21 mainly includes a servo motor, a mounting base, and a cutting tool. The mounting base is rotatably mounted on a slide within the X-axis moving frame 221. The cutting tool is mounted on the mounting base and moves towards the workpiece along the Z-axis. The servo motor is connected to the mounting base and drives the mounting base to rotate, thereby driving the cutting tool to process the workpiece.

[0045] Reference Figure 1 The Y-axis moving frame 231 is mounted on the base 1, the A-axis rotating frame 232 is mounted on the slide of the Y-axis moving frame 231, and the tooling table 3 is mounted on the A-axis rotating frame 232. The servo motor inside the A-axis rotating frame 232 drives the tooling table 3 to rotate along the A-axis. The workpiece is mounted on the tooling table 3. Therefore, under the drive of the Y-axis moving frame 231 and the A-axis rotating frame 232, the workpiece can slide along the Y-axis and rotate along the A-axis, and cooperate with the spindle head 21 to move along the X-axis and Z-axis, so as to realize multi-angle machining of the workpiece, enabling the horizontal machining center to operate flexibly in multiple directions, and increasing the range and accuracy of machining workpieces of multiple sizes.

[0046] Reference Figure 2 In this embodiment, the arrangement component 41 includes an arrangement plate 411, with two arrangement plates 411 arranged opposite to each other. Each arrangement plate 411 has a base plate 412 that slides on the tooling table 3. In this embodiment, there are two sets of fastening components 5, which are located on the two edges of the arrangement plate 411 respectively. Each set of fastening components 5 includes a drive motor 51 and a drive screw 52. The drive motor 51 is a servo motor and is fixedly mounted to the tooling table 3. The drive screw 52 is coaxially fixedly mounted on the output shaft of the drive motor 51. A rotating support for supporting the drive screw 52 is provided on the worktable.

[0047] Reference Figure 2The drive screw 52 has threaded sections with opposite directions at both ends. Each threaded section corresponds to a base plate 412. The drive screw 52 passes through the base plate 412 and is threadedly connected to the arrangement plate 411. When the drive motor 51 drives the drive screw 52 to rotate, the two arrangement plates 411 move closer or further apart. The drive motor 51 drives the drive screw 52 to rotate. By using the threaded sections with opposite directions on the screw to connect with the arrangement plates 411, the two sets of arrangement plates 411 can be driven to move relative to each other accurately and stably, so as to realize the reliable clamping and fixing of the workpiece by the two clamping plates 6 that are set opposite to each other.

[0048] Reference Figure 3 , Figure 4 The arrangement plate 411 is provided with a plurality of placement cavities 413. Each placement cavity 413 extends through the arrangement plate 411 along the moving direction of the arrangement plate 411. In this embodiment, there are four placement cavities 413, which are arranged at intervals along the vertical direction. Each placement cavity 413 of the arrangement plate 411 is provided with a clamping plate 6. Each clamping plate 6 is provided with a clamping groove 61 with a radius of R. The radius R of the clamping groove 61 on the four clamping plates 6 corresponds to four different sizes of workpieces. The clamping plates 6 of the same specification on two arrangement plates 411 are at the same height, and the clamping grooves 61 on the two clamping plates 6 are arranged opposite to each other. The workpieces are clamped and fixed by the clamping grooves 61 of the two clamping plates 6, thus completing the fixed installation of the workpieces on the tooling table 3.

[0049] Reference Figure 3 , Figure 4 A retaining edge 414 is provided at the outer edge of the placement cavity 413. When the clamping plate 6 is fully inserted into the placement cavity 413, the clamping plate 6 fits against the retaining edge 414. The retaining edge 414 positions the clamping plate 6 and restricts it from sliding out of the placement cavity 413, keeping it stable within the placement cavity 413. Placing the clamping plate 6 in the placement cavity 413 facilitates the orderly storage of clamping plates 6 with different radius clamping slots 61, avoiding mutual interference, and protecting the clamping plate 6 from external collisions. It also provides convenience for quickly selecting a suitable clamping plate 6 according to the workpiece radius.

[0050] Reference Figure 3 , Figure 5In this embodiment, the clamping and mounting assembly 42 includes a linear drive mechanism 421, an upper clamping plate 422, and a lower clamping plate 423. There are two sets of linear drive mechanisms 421, with four placement cavities 413 located between the two sets of linear drive mechanisms 421. The linear drive mechanism 421 in this embodiment includes a rotary motor 4211 and a drive screw 4212. The rotary motor 4211 is fixedly embedded in the substrate 412. The drive screw 4212 is vertically positioned on opposite sides of the two arrangement plates 411. Both ends of the drive screw 4212 are connected to the arrangement plates 411 via support rods. The drive screw 4212 is rotatably connected to the support rods. The drive screw 4212 is coaxially fixed to the output shaft of the rotary motor 4211, allowing the rotary motor 4211 to drive the drive screw 4212 to rotate.

[0051] Reference Figure 5 , Figure 6 The lower clamping plate 423 is slidably disposed on the opposite sides of the two arrangement plates 411, and two active screws 4212 pass through both ends of the lower clamping plate 423 and are threadedly connected to the lower clamping plate 423, so that the rotational motion of the active screws 4212 is converted into the up-and-down sliding motion of the lower clamping plate 423. The thickness of the lower clamping plate 423 is equal to or less than the thickness of the portion between two adjacent placement cavities 413. A first guide groove 4241 is provided on the bottom wall of each placement cavity 413. The first guide groove 4241 is arranged along the sliding direction of the arrangement plate 411. A second guide groove 4242 is provided on the lower clamping plate 423 that can be opposite to the first guide groove 4241. When the upper surface of the lower clamping plate 423 is aligned with the bottom wall of the placement cavity 413, the first guide groove 4241 and the second guide groove 4242 are aligned. Each clamping plate 6 is fixedly provided with a guide block 4243. The guide block 4243 cooperates with the first guide groove 4241 and the second guide groove 4242, and slides into the second guide groove 4242 along the first guide groove 4241. The end of the second guide groove 4242 forms a positioning surface 4244. When the guide block 4243 is in contact with the positioning surface 4244, the clamping plate 6 stops sliding. The first guide groove 4241 and the second guide groove 4242 are dovetail-shaped, and the guide block 4243 is also dovetail-shaped to cooperate with the first guide groove 4241 and the second guide groove 4242.

[0052] Reference Figure 5The upper clamping plate 422 is located above the lower clamping plate 423. The length of the upper clamping plate 422 is less than the length of the lower clamping plate 423, so that the active screw 4212 is located on both sides of the upper clamping plate 422. A blocking part 4245 is fixedly provided on the bottom wall of the upper clamping plate 422. The blocking part 4245 is perpendicular to the upper clamping plate 422 and integrally formed. The upper clamping plate 422 and the lower clamping plate 423 are connected by a pressing element 425. In this embodiment, there are two pressing elements 425, which are respectively provided at both ends of the upper clamping plate 422 and the lower clamping plate 423. The pressing element 425 includes a first electromagnet 4251 and a second electromagnet 4252. The first electromagnet 4251 is embedded in the side of the lower clamping plate 423 facing the upper clamping plate 422, and the second electromagnet 4252 is embedded in the side of the upper clamping plate 422 facing the lower clamping plate 423.

[0053] When the clamping plate 6 slides down the upper and lower clamping plates 423, the first electromagnet 4251 and the second electromagnet 4252 generate magnetic fields of opposite polarities at their opposite ends, causing the upper clamping plate 422 to slide downwards and positioning the blocking part 4245 at the rear end of the clamping plate 6. The upper clamping plate 422 presses the clamping plate 6 firmly against the lower clamping plate 423, improving the stability of the clamping plate 6 mounted on the lower clamping plate 423. The blocking part 4245 can move to the rear end of the clamping plate 6 and abut against it, providing support for the clamping plate 6 and making it more stable during operation, further improving the reliability of workpiece clamping and fixing.

[0054] Reference Figure 5 A guide rod 426 is fixedly provided at the bottom of the upper clamping plate 422. The guide rod 426 passes through the lower clamping plate 423, and a limiting block 427 is fixedly provided at one end of the lower clamping plate 423. When it is necessary to clamp the plate 6 to slide on the upper and lower clamping plates 423, the opposite ends of the first electromagnet 4251 and the second electromagnet 4252 generate the same magnetic poles, so that the upper clamping plate 422 slides away from the lower clamping plate 423. When the limiting block 427 abuts against the lower clamping plate 423, the upper clamping plate 422 stops sliding. At this time, a space is formed between the blocking part 4245 and the lower clamping plate 423 for clamping the plate 6 to slide on the upper and lower clamping plates 423. By using the first electromagnet 4251 and the second electromagnet 4252 to generate positive and negative magnetic fields, the clamping and releasing of the upper clamping plate 422 on the clamping plate 6 can be flexibly controlled. This allows for quick and easy replacement of clamping plates 6 with different radii to meet the clamping requirements of workpieces of various sizes, thus improving the convenience of clamping operations during the processing of workpieces of various sizes in the horizontal machining center.

[0055] After the upper and lower clamping plates 423 clamp the clamping plate 6 on the lower clamping plate 423, the rotary motor 4211 drives the drive screw 4212 to rotate. The drive screw 4212 drives the lower clamping plate 423 and the upper clamping plate 422 to slide in the vertical direction. The clamping height of the clamping plate 6 on the workpiece can be adjusted according to the height of the workpiece, thereby improving the stability and firmness of the clamping plate 6 in clamping and fixing the workpiece, and improving the stability of the workpiece installed on the tooling table 3.

[0056] Reference Figure 7 In this embodiment, the feeding component 43 includes a rotary hydraulic cylinder 431 and a lever 432. The rotary hydraulic cylinder 431 is connected to an external hydraulic oil supply system, and the rotation of the main shaft of the rotary hydraulic cylinder 431 is driven by the hydraulic oil. The rotary hydraulic cylinder 431 corresponds one-to-one with the clamping plate 6, and each rotary hydraulic cylinder 431 is fixedly installed on the back of the arrangement plate 411.

[0057] Reference Figure 7 In this embodiment, the lever 432 includes a lever body 4321 and a third electromagnet 4322. The lever body 4321 is fixedly connected to the main shaft of the rotary hydraulic cylinder 431. The rotary hydraulic cylinder 431 drives the lever body 4321 to rotate in the horizontal direction and can drive the end of the lever body 4321 to insert into the placement cavity 413, pushing out the clamping plate 6 in the placement cavity 413. The third electromagnet 4322 is located at the end of the rod 4321. When the rod 4321 pushes out the clamping plate 6, the third electromagnet 4322 is de-energized, and the rod 4321 pushes the clamping plate 6 out of the placement cavity 413 and slides onto the upper and lower clamping plates 423. After the clamping plate 6 is used, the rotating hydraulic cylinder 431 drives the rod 4321 through the placement cavity 413, so that the third electromagnet 4322 contacts the clamping plate 6. Then, the third electromagnet 4322 is energized to attract the clamping plate 6. Then, the rotating hydraulic cylinder 431 is flipped, and the rod 4321 pulls the clamping plate 6 back into the placement cavity 413 to reset it. This makes it convenient to select a suitable clamping plate 6 for the next use, realizing convenient storage and recycling of the clamping plate 6.

[0058] All of the above technical solutions use motor and hydraulic cylinder control. The motor and hydraulic cylinder involved in the above solutions can be controlled by setting a logic control program to realize automatic replacement of the clamping plate 6 that is compatible with the workpiece and automatic clamping of the workpiece.

[0059] The implementation principle of a horizontal machining center for producing multi-size workpieces according to an embodiment of this application is as follows: When installing the workpiece onto the horizontal machining center, the workpiece is first placed at the center of the tooling table 3. Then, a corresponding clamping plate 6 is selected according to the diameter of the workpiece. Then, the rotary motor 4211 drives the lower clamping plate 423 to slide to the placement cavity 413 where the corresponding clamping plate 6 is located. The opposite ends of the first electromagnet 4251 and the second electromagnet 4252 generate the same polarity, and the upper clamping plate 422 moves away from the lower clamping plate 423, so that the upper part of the lower clamping plate 423 opens. Then, the corresponding rotary hydraulic cylinder 431 is driven to rotate. The rotary hydraulic cylinder 431 drives the rod 4321 to push out the corresponding clamping plate 6. The clamping plate 6 slides along the first guide groove 4241 into the second guide groove 4242 and stops moving under the positioning surface 4244, so that the clamping plate 6 slides completely onto the lower clamping plate 423.

[0060] Then, the first electromagnet 4251 and the second electromagnet 4252 generate opposite polarities, causing the upper clamping plate 422 to move down onto the lower clamping plate 423. The blocking part 4245 is inserted into the rear end of the clamping plate 6. At this time, neither the upper clamping plate 422 nor the lower clamping plate 423 blocks the clamping groove 61. Then, the rotary motor 4211 drives the drive screw 4212 to rotate. The drive screw 4212 drives the lower clamping plate 423 and the upper clamping plate 422 to slide in the vertical direction. The clamping height of the clamping plate 6 on the workpiece can be adjusted according to the height of the workpiece.

[0061] After the clamping height of the clamping plate 6 is adjusted, the drive motor 51 drives the drive screw 52 to rotate. By using the two threaded sections on the screw with opposite directions of rotation to connect with the threaded section of the arrangement plate 411, the two sets of arrangement plates 411 can be driven to move relative to each other in a precise and stable manner, so as to realize the reliable clamping and fixing of the workpiece by the two clamping plates 6 that are set opposite to each other.

[0062] After the clamping plate 6 finishes clamping, the rotary motor 4211 drives the clamping plate 6 to move to the corresponding placement cavity 413. The first electromagnet 4251 and the second electromagnet 4252 generate the same polarity on opposite sides, causing the upper clamping plate 422 to move away from the lower clamping plate 423, releasing the clamping of the clamping plate 6. The rotary hydraulic cylinder 431 drives the rod 4321 to pass through the placement cavity 413, so that the third electromagnet 4322 contacts the clamping plate 6. Then, the third electromagnet 4322 is energized to attract the clamping plate 6. Then, the rotary hydraulic cylinder 431 is flipped, and the rod 4321 pulls the clamping plate 6 back into the placement cavity 413 for reset.

[0063] By setting clamping plates 6 with clamping slots 61 of different radii, compared with the prior art which can only clamp and fix workpieces of one radius, this application can select clamping plates 6 of the corresponding radius to clamp and fix the workpiece according to the different radii of the workpiece, thereby improving the flexibility of clamping and fixing the workpiece and the convenience of clamping and fixing workpieces of different radii.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
