Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1-18 shown, the embodiment of the present invention provides a clamping device for processing a cooling roller of a spinning machine, including an adapter component 3, and the adapter component 3 is used to adapt to the clamping of the three-jaw chuck of a lathe; The adapter component 3 includes a head shaft 301, one end of the head shaft 301 is fixedly connected with a head plate 302, the other end of the head shaft 301 is fixedly connected with a limiting block 304, and a jaw slot 305 for adapting to the jaws of the three-jaw chuck of the lathe is provided between adjacent limiting blocks 304, and an adapter slot 303 is provided at the center of the head plate 302; Referring to Figure 1 , Figure 3 , Figure 6 , the jaw slot 305 is used to meet the clamping requirements of the jaws of the three-jaw chuck of the lathe, the head plate 302 is used to be connected with the tail plate 402 or the connecting disk 608, and can be connected by bolts and nuts, and is convenient for disassembly and replacement when the adapter component 3 is damaged. The adapter slot 303 is used to be connected with the convex block 609 to ensure the stable rotation of the clamping component 2.

[0020] The clamping member 2, the clamping member 2 includes a moving member 5, a fixed member 6, an axial member 7, a radial member 8, and a locking member. The axial member 7 is used to provide a clamping force in the axial direction. The axial member 7 includes an axial rod 702 slidably mounted on the moving member 5. One end of the axial rod 702 is fixedly connected with a stop block 701, and the other end of the axial rod 702 is fixedly connected with an axial jaw 704. An axial spring 703 is sleeved on the axial rod 702 and on the side close to the axial jaw 704; Reference Figure 7 , Figure 8 , Figure 9 , Figure 16 , the axial rod 702 can axially slide in the axial hole 506 of the moving member 5. When not under force, due to the elastic force of the axial spring 703, the axial jaw 704 will be in a stable state; when the axial spring 703 is pushed by the moving member 5, the axial spring 703 will be compressed, so as to provide an axial clamping force to the axial jaw 704. The greater the compression deformation of the axial spring 703, the greater the axial clamping force provided to the axial jaw 704. The stop block 701 prevents the axial rod 702 from moving excessively. The longitudinal section of the axial jaw 704 is in a three-claw shape, which is used to increase the contact area and prevent the axial jaw 704 from damaging the roller workpiece 1; the side surface of the axial jaw 704 close to the roller workpiece 1 is arranged in an arc shape. Therefore, the axial jaw 704 can be in contact with the end of the roller workpiece 1. Therefore, the material strength of the axial rod 702 and the axial jaw 704 itself can provide a clamping force in the radial direction to the roller workpiece 1, and cooperate with the radial member 8 to ensure the stability of the roller workpiece 1.

[0021] An observation port 7041 is provided at the rear of the axial jaw 704. An indicating needle 10 is rotatably connected inside the axial jaw 704. Contact members 9 and guide sleeves 7042 are symmetrically arranged on the outside of the indicating needle 10. The guide sleeve 7042 is slidably matched with the contact member 9; the contact member 9 includes a lower arc rod 902 and an upper arc rod 905. A contact ball 901 is movably connected to the lower part of the lower arc rod 902. The upper end of the upper arc rod 905 is rotatably connected with the indicating needle 10. The lower end of the upper arc rod 905 is fixedly connected with an arc-shaped sleeve 904. The arc-shaped sleeve 904 is slidably matched with the lower arc rod 902. A spring piece 903 is arranged between the lower arc rod 902 and the arc-shaped sleeve 904; Reference Figure 17 , Figure 18, when the axial jaw 704 contacts and clamps the circumferential surface of the roller workpiece 1, the contact ball 901 contacts the roller workpiece 1, generating a radial thrust. The contact ball 901 drives the lower arc rod 902 to move radially outward, thereby pushing the elastic piece 903 and causing the elastic piece 903 to deform and compress. If the circumferential surface of the roller workpiece 1 is a standard circle, the displacement amounts of the two symmetric contact balls 901 are the same. Therefore, the elastic deformation amounts of the elastic piece 903 are the same, and the thrusts on both sides of the indicating needle 10 are the same. At this time, the indicating needle 10 is located in the middle of the observation port 7041. If the circumferential surface of the roller workpiece 1 deforms, the displacement amounts of the two contact balls 901 on both sides are different. Therefore, the generated thrusts are different. If the left thrust is greater than the right thrust, then the indicating needle 10 will deflect to the right. Conversely, it will deflect to the left. Through the state of the indicating needle 10, the runout amount of the circumferential surface of the roller workpiece 1 can be visually shown, which can improve the processing quality of the roller workpiece 1 and also determine whether the hollow part of the roller workpiece 1 deforms, which is beneficial to controlling the processing quality of the cooling roller workpiece.

[0022] The radial member 8 is used to provide a clamping force in the radial direction. The radial member 8 includes a radial frame 801 fixedly installed on the moving member 5. A sliding sleeve 802 is fixedly connected to the lower edge of the radial frame 801. A sliding member 807 is slidably installed inside the radial frame 801. The lower end of the sliding member 807 is fixedly connected to a radial jaw 804. A radial spring 806 is sleeved on the sliding member 807 and close to one side of the radial jaw 804. A permanent magnet 805 is fixedly installed in the middle of the radial jaw 804. An electromagnet 803 is provided above the permanent magnet 805. The electromagnet 803 is fixedly installed on the radial frame 801. A shielding piece 8041 for shielding the radial spring 806 is fixedly connected to the radial jaw 804. The magnetic properties of the permanent magnet 805 and the electromagnet 803 are opposite when they are energized; Reference Figure 8 、 Figure 9 、 Figure 12 、 Figure 13 , the sliding sleeve 802 can be penetrated by the secondary sliding strip 604 to ensure the stability of the radial frame 801. During clamping, the electromagnet 803 is in an unpowered state. Under the elastic force of the radial spring 806, the radial jaw 804 provides a radial clamping force for the roller workpiece 1; when the roller workpiece 1 needs to be placed or taken out, the electromagnet 803 can work under the action of its own battery, generate magnetism to adsorb the permanent magnet 805, and the magnetic force is greater than the elastic force of the radial spring 806. Therefore, the radial jaw 804 will move away from the roller workpiece 1, thus facilitating the placement or taking out of the roller workpiece 1. Among them, the battery part is not shown in the figure. In other embodiments, the battery can be external and only powered by an external power supply when the rotation stops, which can also meet the use of the electromagnet 803.

[0023] The fixing member 6 is used to provide the power for self-rotation. The fixing member 6 includes a fixing disk 601. On the fixing disk 601, fixing sleeves 602, secondary sliding strips 604, and primary sliding strips 605 are evenly and fixedly connected in a circumferential manner. An installation block 603 is fixedly connected to the upper fixing sleeve 602. At the center of the fixing disk 601, a connection disk 608 and a support shaft 607 are fixedly connected. At the center of the connection disk 608, a convex block 609 is fixedly connected. The ends of the primary sliding strip 605 and the secondary sliding strip 604 away from the fixing disk 601 are fixedly connected to a fixing plate 606; Reference Figure 14 , Figure 15 , the connection disk 608 and the convex block 609 are used to connect with the adapter assembly 3 for transmitting the power of self-rotation. The installation block 603 is provided with a through hole for accommodating a locking screw to facilitate locking and installation; the support shaft 607 is used to be inserted into the end of the roller workpiece 1 from the end to provide support for the roller workpiece 1, avoiding deformation of the roller workpiece 1 due to clamping force and ensuring good quality of the roller workpiece 1; while providing support for the fixing plate 606, the primary sliding strip 605 and the secondary sliding strip 604 also provide a guiding function for the movement of the moving member 5 to ensure the stability of the movement of the moving member 5; the fixing plate 606 is provided with a channel for accommodating the roller workpiece 1; the primary sliding strip 605 is located outside the secondary sliding strip 604, and the cross-sectional size of the primary sliding strip 605 is larger than that of the secondary sliding strip 604.

[0024] The moving member 5 is used to control the movement of the radial member 8 and the axial member 7. The moving member 5 includes a moving ring 501. An operation ring 502 is fixedly connected to the upper part of the moving ring 501. Connecting plates 503 are evenly and fixedly connected to the moving ring 501 in a circumferential manner. One end of the connecting plate 503 away from the moving ring 501 is fixedly connected to an arc plate 504. The arc plate 504 is provided with sliding holes 505 and axial holes 506 for installing the fixing member 6 and the axial member 7; Reference Figure 10 , Figure 11 , Figure 7 , the moving ring 501 is used to connect multiple connecting plates 503 together. By operating the operation ring 502, multiple connecting plates 503 can be controlled to move synchronously. The arc plate 504 is used to adapt to the primary sliding strip 605. The connecting plate 503 passes through the fixing sleeve 602, and the connecting plate 503 is provided with a plurality of locking holes, and the locking holes can be in threaded cooperation with the locking screws to facilitate locking and installation.

[0025] The locking component is used to lock the moving member 5 and the fixing member 6 into one body. The locking component includes a locking screw; Reference Figure 7 , during the locking operation, just turn the locking screw. When locking is not required, remove the locking screw.

[0026] The tail assembly 4 is used to provide an installation position for the clamping member 2 at the tail; The tail assembly 4 includes a tailstock 401. A tailshaft 403 is rotatably connected to the upper part of the tailstock 401. A tail plate 402 is fixedly connected to the tailshaft 403. An adaptation groove 303 is provided at the center of the tail plate 402. Reference Figure 5 , Figure 4 , Figure 1 , the tailstock 401 is used to be installed on a lathe. Through the moving parts of the lathe itself, the tailstock 401 can be driven to move to adapt to roller workpieces 1 of different lengths. The tailshaft 403 can rotate on its own. Through the tail plate 402, the stable rotation of the clamping part 2 at the tail can be ensured, ensuring good quality of workpiece turning. The present invention is suitable for turning of roller workpieces 1 with a relatively large radius and a relatively small wall thickness.

[0027] Working principle: When in use, first install the clamping part 2 on the adaptation assembly 3 and the tail assembly 4, install the adaptation assembly 3 on the three-jaw chuck of the lathe, and install the tail assembly 4 at the tail of the lathe; First, the electromagnet 803 can work under the action of its own built-in battery, generate magnetism to adsorb the permanent magnet 805, and the magnetic force is greater than the elastic force of the radial spring 806. Therefore, the radial jaws 804 will move away from the roller workpiece 1, and then one end of the roller workpiece 1 is placed on the support shaft 607. Similarly, the other end of the roller workpiece 1 is placed on the support shaft 607 at the tail; Then unscrew the locking screw. By operating the ring 502, multiple connecting plates 503 can be controlled to move synchronously. The connecting plates 503 drive the arc plate 504 to move, thereby driving the axial part 7 in the axial hole 506 to move. When the axial jaws 704 are restricted by the roller workpiece 1, when the axial spring 703 is subjected to the thrust of the moving part 5, the axial spring 703 will be compressed, thereby providing an axial clamping force to the axial jaws 704. The greater the compression deformation of the axial spring 703, the greater the axial clamping force provided to the axial jaws 704. Then screw on the locking screw to lock the moving part 5; When the axial jaw 704 is in contact with and clamps the circumferential surface of the roller workpiece 1, the contact ball 901 contacts the roller workpiece 1, generating a radial thrust. The contact ball 901 drives the lower arc rod 902 to move radially outward, thereby pushing the elastic piece 903 and causing the elastic piece 903 to deform and compress. If the circumferential surface of the roller workpiece 1 is a standard circle, the displacement amounts of the two symmetric contact balls 901 are the same. Therefore, the elastic deformation amounts of the elastic piece 903 are the same, and the thrusts on both sides of the indicating needle 10 are the same. At this time, the indicating needle 10 is located in the middle of the observation port 7041. If the circumferential surface of the roller workpiece 1 deforms, the displacement amounts of the contact balls 901 on both sides are different. Therefore, the generated thrusts are different. If the left thrust is greater than the right thrust, then the indicating needle 10 will deflect to the right. Conversely, it will deflect to the left. Through the state of the indicating needle 10, the runout amount of the circumferential surface of the roller workpiece 1 can be visually shown, the processing quality of the roller workpiece 1 can be improved, and it can also be judged whether the hollow part of the roller workpiece 1 deforms, which is beneficial to controlling the processing quality of the cooling roller workpiece; Then the electromagnet 803 is in an unenergized state. Under the elastic force of the radial spring 806, the radial jaw 804 provides a radial clamping force for the roller workpiece 1. With the support of the support shaft 607, the end of the roller workpiece 1 can be prevented from deforming, ensuring the stability of the clamping, and thus completing the overall clamping operation of the roller workpiece 1.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
