Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to a clamping device for a tungsten carbide roller ring. Background Technology

[0002] Tungsten carbide roller rings are tools used for machining cemented carbide. They are usually made by mixing tungsten carbide (WC) powder with metal powders (such as nickel, cobalt, etc.) and then pressing and sintering them. Tungsten carbide roller rings have the characteristics of high hardness, high wear resistance and high strength, so they are widely used in the field of cemented carbide machining.

[0003] Existing tungsten carbide roller ring clamping devices require fixing one tungsten carbide roller ring before installing and clamping the next one. This results in low efficiency for workers fixing tungsten carbide roller rings, increases labor costs, and also makes it easy for adjacent tungsten carbide roller rings to collide during movement, causing wear and affecting the performance. Utility Model Content

[0004] The main objective of this disclosure is to provide a clamping device for tungsten carbide roller rings to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A clamping device for a tungsten carbide roller ring includes a support rod. A fixing plate is uniformly fixedly mounted on the circumferential surface of the support rod. A fixing block is fixedly mounted on the right side of the fixing plate. The fixing block has symmetrically formed mounting grooves at its upper and lower ends on the side away from the fixing plate. A tension spring is fixedly mounted inside the mounting groove. A collar is fixedly connected to the end of the tension spring away from the fixing block. The collar is movably sleeved on the circumferential surface of the support rod. The collar has symmetrically formed connecting grooves at its upper and lower ends on its left side. The end of the tension spring away from the fixing block is fixedly mounted in the connecting groove. A fixing ring is fixedly mounted on the right side of the collar. A tungsten carbide roller ring is movably mounted between the fixing plate and the fixing ring. The upper inner wall of the tungsten carbide roller ring abuts against the upper circumferential surface of the fixing block and the collar. Connecting ears are fixedly mounted at the left and right ends of the support rod and at the middle of the upper part of the circumferential surface.

[0007] Preferably, the left side of the fixed ring has symmetrically formed movable grooves at the middle of both ends, and a clamping plate is rotatably connected in the movable grooves. The circumferential surface of the collar has symmetrically formed slots on both sides, and the clamping plate is movably installed in the slots. A through groove is formed at the middle of the end of the clamping plate away from the fixed ring, and a return spring is movably installed in the through groove. A limit post is movably inserted into the open end of the through groove. Limit holes are formed at the middle of both sides of the end of the fixed block away from the fixed plate, and the end of the limit post away from the clamping plate is movably inserted into... The tungsten carbide roller rings of different models are inserted into the limiting hole. The operator moves the roller rings of different models through the support rod between the fixed plate and the fixed ring. Then, the fixed ring is pulled outward, allowing it to move along with the clamping plate. The clamping plate then slides out of the limiting hole along with the limiting post. The clamping plate is then pulled outward, allowing it to insert into the movable groove. The fixed ring is then released, allowing the tension spring to press against the fixed ring and the clamping plate against the tungsten carbide roller rings. This allows the clamping plate to clamp and fix the tungsten carbide roller rings of different models, thus improving the applicability of the fixed ring.

[0008] Preferably, the front and rear sides of the fixing ring are symmetrically provided with circular grooves, and a coil spring is movably installed in the circular groove. A rotating shaft is fixedly installed on the right end of the upper and lower sides of the clamping plate. One end of the coil spring is fixedly connected to the inner wall of the circular groove, and the other end of the coil spring is fixedly connected to the circumferential surface of the rotating shaft. By providing symmetrical circular grooves on the front and rear sides of the fixing ring, and connecting the rotating shaft and the circular groove with the coil spring, the clamping plate can be rotated by the coil spring when the fixing ring is pulled to move it, thus making it easier to pull the clamping plate out of the slot and improving work efficiency.

[0009] Preferably, a protective pad is fixedly installed on the inward side of the fixing plate and the fixing ring; this reduces the wear of the fixing plate and the fixing ring on the tungsten carbide roller ring, thereby increasing the service life of the tungsten carbide roller ring.

[0010] Preferably, the inner diameter of the tungsten carbide roller ring is larger than the outer diameter of the fixing plate and the fixing ring, and the length of the clamping plate is larger than the radius of the tungsten carbide roller ring; this allows the tungsten carbide roller ring to be placed more easily and conveniently between the fixing plate and the fixing ring, while also clamping and fixing the tungsten carbide roller ring more stably, thus improving work efficiency.

[0011] Preferably, an anti-slip pad is fixedly installed on the inward side of the clamping plate; this increases the friction between the clamping plate and the tungsten carbide roller ring, thereby allowing the clamping plate to clamp and fix the tungsten carbide roller ring more stably.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, the worker passes different types of tungsten carbide roller rings through the circumferential surface of the support rod, and then pulls the fixing ring outward, so that the fixing ring moves through the collar pulling the tension spring. Then, the tungsten carbide roller ring is placed between the fixing plate and the fixing ring, so that the upper inner wall of the tungsten carbide roller ring abuts against the upper circumferential surface of the fixing block and the collar. Then, the fixing ring is released, so that the tension spring moves through the collar with the fixing ring, thereby fixing and clamping different types of tungsten carbide roller rings between the fixing plate and the fixing ring, improving the efficiency of the worker in clamping and fixing the tungsten carbide roller rings.

[0014] (II) In this application, when the worker moves different types of tungsten carbide roller rings through the support rod to between the fixed plate and the fixed ring, and then pulls the fixed ring outward, the fixed ring moves along with the clamping plate. Then the clamping plate slides out of the limiting hole along with the limiting post. Then the clamping plate is pulled outward, so that the clamping plate is inserted into the movable groove. Then the fixed ring is released, so that the tension spring moves the fixed ring and the clamping plate against the tungsten carbide roller ring, thereby allowing the clamping plate to clamp and fix different types of tungsten carbide roller rings, thus improving the applicability of the fixed ring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides the following embodiments:

[0022] A clamping device for a tungsten carbide roller ring includes a support rod 1. A fixing plate 2 is uniformly fixedly installed on the circumferential surface of the support rod 1. A fixing block 3 is fixedly installed on the right side of the fixing plate 2. The fixing block 3 has symmetrically formed mounting grooves 4 at its upper and lower ends on the side away from the fixing plate 2. A tension spring 5 is fixedly installed inside the mounting groove 4. A collar 6 is fixedly connected to the end of the tension spring 5 away from the fixing block 3. The collar 6 is movably sleeved on the circumferential surface of the support rod 1. A connecting groove 7 is symmetrically formed at its upper and lower ends on the left side of the collar 6. The end of the tension spring 5 away from the fixing block 3 is fixedly installed in the connecting groove 7. A fixing ring 8 is fixedly installed on the right side of the collar 6. A tungsten carbide roller ring 9 is movably installed between the fixing plate 2 and the fixing ring 8. The upper inner wall of the tungsten carbide roller ring 9 is flush with the fixing block 3. The upper circumferential surface of the collar 6 abuts against the support rod 1. Connecting ears 10 are fixedly installed at the left and right ends and the middle of the upper part of the circumferential surface. The operator passes different models of tungsten carbide roller rings 9 through the circumferential surface of the support rod 1, and then pulls the fixing ring 8 outward, so that the fixing ring 8 moves through the collar 6 to pull the tension spring 5. Then, the tungsten carbide roller ring 9 is placed between the fixing plate 2 and the fixing ring 8, so that the upper inner wall of the tungsten carbide roller ring 9 abuts against the upper circumferential surface of the fixing block 3 and the collar 6. Then, the fixing ring 8 is released, so that the tension spring 5 moves through the collar 6 to carry the fixing ring 8, thereby fixing and clamping different models of tungsten carbide roller rings 9 between the fixing plate 2 and the fixing ring 8, thereby improving the efficiency of the operator in clamping and fixing the tungsten carbide roller ring 9.

[0023] Specifically, the left side of the fixed ring 8 has symmetrically arranged movable grooves 11 at the middle of both ends, and a clamping plate 12 is rotatably connected in the movable grooves 11. The circumferential surface of the collar 6 has symmetrically arranged slots 13 on both sides, and the clamping plate 12 is movably installed in the slots 13. A through groove 17 is opened at the middle of the end of the clamping plate 12 away from the fixed ring 8, and a return spring 18 is movably installed in the through groove 17. A limit post 19 is movably inserted into the open end of the through groove 17. The fixed block 3 has limit holes 20 at the middle of both sides at the end away from the fixed plate 2, and the end of the limit post 19 away from the clamping plate 12 is movably inserted into... In the limiting hole 20; when the worker moves the tungsten carbide roller ring 9 of different models through the support rod 1 to between the fixed plate 2 and the fixed ring 8, and then pulls the fixed ring 8 outward, the fixed ring 8 moves with the clamping plate 12, and then the clamping plate 12 slides out of the limiting hole 20 with the limiting post 19, and then pulls the clamping plate 12 outward, so that the clamping plate 12 is inserted into the movable groove 11, and then the fixed ring 8 is released, so that the tension spring 5 carries the fixed ring 8 and the clamping plate 12 to abut against the tungsten carbide roller ring 9, so that the clamping plate 12 clamps and fixes the tungsten carbide roller ring 9 of different models.

[0024] Specifically, circular grooves 14 are symmetrically opened on the front and rear sides of the fixing ring 8. A coil spring 15 is movably installed in the circular groove 14. A rotating shaft 16 is fixedly installed on the right end of the upper and lower sides of the clamping plate 12. One end of the coil spring 15 is fixedly connected to the inner wall of the circular groove 14, and the other end of the coil spring 15 is fixedly connected to the circumferential surface of the rotating shaft 16. By symmetrically opening circular grooves 14 on the front and rear sides of the fixing ring 8, and then connecting the rotating shaft 16 and the circular grooves 14 through the coil spring 15, the clamping plate 12 is rotated by the coil spring 15 when the fixing ring 8 is pulled to move the clamping plate 12.

[0025] Specifically, a protective pad is fixedly installed on the inward side of the fixing plate 2 and the fixing ring 8. By fixing the protective pad on the inward side of the fixing plate 2 and the fixing ring 8, the wear of the fixing plate 2 and the fixing ring 8 on the tungsten carbide roller ring 9 can be reduced when the fixing plate 2 and the fixing ring 8 clamp and fix the tungsten carbide roller ring 9, thereby increasing the service life of the tungsten carbide roller ring 9.

[0026] Specifically, the inner diameter of the tungsten carbide roller ring 9 is larger than the outer diameter of the fixing plate 2 and the fixing ring 8, and the length of the clamping plate 12 is larger than the radius of the tungsten carbide roller ring 9. By making the inner diameter of the tungsten carbide roller ring 9 larger than the outer diameter of the fixing plate 2 and the fixing ring 8, and the length of the clamping plate 12 larger than the radius of the tungsten carbide roller ring 9, the tungsten carbide roller ring 9 can be placed between the fixing plate 2 and the fixing ring 8 more easily and conveniently, and the tungsten carbide roller ring 9 can be clamped and fixed more stably.

[0027] Specifically, an anti-slip pad is fixedly installed on the inward side of the clamping plate 12; by fixing the anti-slip pad on the inward side of the clamping plate 12, the friction between the clamping plate 12 and the tungsten carbide roller ring 9 can be increased, thereby allowing the clamping plate 12 to clamp and fix the tungsten carbide roller ring 9 more stably.

[0028] The working principle of this utility model is as follows: The operator passes different models of tungsten carbide roller rings 9 through the circumferential surface of the support rod 1, then pulls the fixing ring 8 outwards, causing the fixing ring 8 to move through the collar 6 and pull the tension spring 5. Then, the tungsten carbide roller ring 9 is placed between the fixing plate 2 and the fixing ring 8, so that the upper inner wall of the tungsten carbide roller ring 9 abuts against the upper circumferential surface of the fixing block 3 and the collar 6. Simultaneously, the fixing ring 8 moves along with the clamping plate 12, and then the clamping plate 12 slides out of the limiting hole 20 along with the limiting post 19. Finally, the clamping plate 12 is pulled outwards, allowing it to insert into the movable slot. In step 11, the fixing ring 8 is then loosened, allowing the tension spring 5 to abut against the fixing ring 8 and the clamping plate 12 against the tungsten carbide roller ring 9. This allows the clamping plate 12 to clamp and fix the tungsten carbide roller ring 9 of different models. Then, the fixing ring 8 is loosened, allowing the tension spring 5 to move along the fixing ring 8 through the collar 6, thereby fixing and clamping the tungsten carbide roller ring 9 of different models between the fixing plate 2 and the fixing ring 8. Then, the steel cable is installed on the connecting ear 10, allowing the crane to move the tungsten carbide roller ring 9 on the support rod 1 more stably, improving the efficiency of the workers in clamping and fixing the tungsten carbide roller ring 9.
