[0002] Rollers are the main working parts of a rolling mill. When working, they can cause continuous plastic deformation of the metal. When producing rolls, they need to be fixed on the mounting seat in the heat treatment box, and then rotated in the heat treatment box for heating.

[0003] For example, the patent with application number 202311335007.4 discloses a multi-specification butt-jointed roller heat treatment mounting seat. Since the end shapes of the rollers are divided into various shapes such as round, flat and rectangular, in order to facilitate the fixation of different rollers, memory metal is used to clamp them, such as the above-mentioned patent. However, the clamping operation is more laborious, and the memory metal will excessively squeeze the protruding position of the roller end when clamping, which is still easy to cause damage to the roller. Summary of the invention

[0004] The utility model provides a fixing device suitable for heat treatment of rollers of various specifications, which is very labor-saving to operate when fixing the rollers, and also does not cause excessive compression of the protruding position of the roller end by metal, thereby further avoiding damage to the rollers.

[0007] Preferably, the first clamping rods are respectively located at the front and rear sides of the roller clamping plate, the second clamping rods are respectively located at the top and bottom of the roller clamping plate, and the two first clamping rods and the two second clamping rods are symmetrical to each other.

[0008] Preferably, four groups of eight cylindrical rods are arranged on the outside of the roller fixing frame, and the two first clamping rods and the two second clamping rods can slide on the outside of the four groups of cylindrical rods respectively.

[0009] Preferably, the threads on the outer sides of the first screw rod and the second screw rod are divided into two sections, and the two sections of threads are symmetrical reverse threads.

[0010] Preferably, the roller clamping plate is provided with four rectangular grooves running through the rollers, the four rectangular grooves are arranged in a cross shape, and the first clamping rod and the second clamping rod can slide in the rectangular grooves.

[0011] Preferably, a trapezoidal rubber block is fixed to the outer side of one end of each of the first clamping rod and the second clamping rod, and the rubber block is wider on one side close to the middle of the roller clamping plate.

[0012] Preferably, the first screw rod and the second screw rod are staggered and arranged in a cross shape as a whole, and the first clamping rod and the second clamping rod are each provided with a threaded hole corresponding to the outer thread of the first screw rod and the second screw rod.

When the distance between the two roller fixing frames 6 needs to be adjusted, the electric cylinder 4 can be controlled to extend and retract. When the electric cylinder 4 extends and retracts, it can drive the No. 2 support plate 5 to slide stably left and right under the support of the guide rods 3, so that the distance between the No. 1 support plate 2 and the No. 2 support plate 5 can be changed, and then the distance between the two roller fixing frames 6 can be adjusted to clamp or loosen the two ends of the rollers; A No. 2 support plate 5 is slidably installed on the outer side of the rod 3, and the No. 2 support plate 5 is also used to rotatably support the roller fixing frame 6; an electric cylinder 4 is also fixed on the top of the base 1, and the right end of the electric cylinder 4 is fixedly connected to the left side of the No. 2 support plate 5. When the distance between the two roller fixing frames 6 needs to be adjusted, the electric cylinder 4 can be controlled to extend and retract. When the electric cylinder 4 extends and retracts, it can drive the No. 2 support plate 5 to slide stably left and right under the support of the guide rod 3, so that the distance between the No. 1 support plate 2 and the No. 2 support plate 5 can be changed; a roller fixing frame 6 is rotatably installed on the top of the No. 1 support plate 2 and the No. 2 support plate 5, and the roller fixing frame 6 is used to clamp the roller 7, the first screw rod 8 and the second screw rod 10 as well as the first clamping rod 9 and the second clamping rod 11 are supported; a roller clamping plate 7 is welded on one side of the roller fixing frame 6. When the spacing between the two roller fixing frames 6 needs to be adjusted, the electric cylinder 4 can be controlled to extend and retract. When the electric cylinder 4 extends and retracts, it can drive the second support plate 5 to slide stably left and right under the support of the guide rod 3, so that the spacing between the first support plate 2 and the second support plate 5 can be changed, and then the spacing between the two roller fixing frames 6 can be adjusted and the two ends of the roller can be clamped or loosened through the roller clamping plate 7; a first screw rod 8 and a second screw rod 10 are rotatably installed on the roller fixing frame 6, When fixing the two ends of the roller, the first screw rod 8 can be driven to rotate by the hand wheel at one end of the first screw rod 8. When the first screw rod 8 rotates, it will drive the two first clamping rods 9 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two first clamping rods 9 can clamp the front and rear sides of the roller end, and then the second screw rod 10 can be driven to rotate by the hand wheel at one end of the second screw rod 10. When the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two second clamping rods 11 can clamp the top and bottom of the roller end, thereby preventing the roller from moving, and can clamp and fix the roller ends of different specifications;Two first clamping rods 9 and two second clamping rods 11 are also slidably mounted on the roller fixing frame 6. When fixing the two ends of the roller, the first screw rod 8 can be first driven to rotate by the hand wheel at one end of the screw rod 8. When the first screw rod 8 rotates, it will drive the two first clamping rods 9 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two first clamping rods 9 can clamp the front and rear sides of the roller end. Then, the second screw rod 10 is driven to rotate by the hand wheel at one end of the screw rod 10. When the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two second clamping rods 11 can clamp the top and bottom of the roller end. ;

[0030] In the present disclosure, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first clamping rod 9 is respectively located at the front and rear sides of the roller clamping plate 7, and the second clamping rod 11 is respectively located at the top and bottom of the roller clamping plate 7, and the two first clamping rods 9 and the two second clamping rods 11 are symmetrical to each other. When the two ends of the roller are fixed, the first screw rod 8 can be first driven to rotate by the handwheel at one end of the screw rod 8. When the first screw rod 8 rotates, it will drive the two first clamping rods 9 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two first clamping rods 9 can clamp the front and rear sides of the roller end, and then the second screw rod 10 is driven to rotate by the handwheel at one end of the screw rod 10. When the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two second clamping rods 11 can clamp the top and bottom of the roller end.

[0031] In the present disclosure, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, four groups of eight cylindrical rods are arranged on the outside of the roller fixing frame 6, and two first clamping rods 9 and two second clamping rods 11 can slide on the outside of these four groups of cylindrical rods respectively, thereby improving the stability of the first clamping rods 9 and the second clamping rods 11 when sliding, and the first clamping rods 9 and the second clamping rods 11 will be more stable when clamping the roller ends.

[0032] In the present disclosure, Figure 4 and Figure 5 As shown, the threads on the outer sides of the first screw rod 8 and the second screw rod 10 are divided into two sections, and the two sections of threads are symmetrical reverse threads, so when the first screw rod 8 rotates, it will drive the two first clamping rods 9 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, and when the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6.

[0033] In the present disclosure, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the roller clamping plate 7 is provided with four rectangular grooves running through it from left to right, and the four rectangular grooves are arranged in a cross shape, and the first clamping rod 9 and the second clamping rod 11 can slide in the rectangular grooves, so the first clamping rod 9 and the second clamping rod 11 can be adjusted arbitrarily, and the contact area between the roller clamping plate 7 and the roller end is also larger.

[0034] In the present disclosure, Figure 1 , Figure 2 and Figure 6 As shown, the first screw rod 8 and the second screw rod 10 are arranged alternately, and the first screw rod 8 and the second screw rod 10 are arranged in a cross shape as a whole. The first clamping rod 9 and the second clamping rod 11 are each provided with a threaded hole corresponding to the outer thread of the first screw rod 8 and the second screw rod 10. When fixing the two ends of the roller, the first screw rod 8 can be first driven to rotate by the handwheel at one end of the first screw rod 8. When the first screw rod 8 rotates, it will drive the two first clamping rods 9 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two first clamping rods 9 can clamp the front and rear sides of the roller end, and then the second screw rod 10 is driven to rotate by the handwheel at one end of the second screw rod 10. When the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two second clamping rods 11 can clamp the top and bottom of the roller end.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, a trapezoidal rubber block is fixed to the outer side of one end of the first clamping rod 9 and the second clamping rod 11, and the rubber block is wider on one side close to the middle of the roller clamping plate 7. Therefore, when the first clamping rod 9 and the second clamping rod 11 clamp the end of the roller, the wider side of these trapezoidal rubber blocks will be in close contact with the outer wall of the end of the roller, thereby increasing the friction force to prevent loosening and avoiding wear on the roller.

[0036] The working principle of this embodiment is as follows: when installing this device, first fix the base 1 in the heat treatment box. When fixing the roller, first place the roller between the two roller fixing frames 6. Then the electric cylinder 4 can be controlled to contract. When the electric cylinder 4 contracts, it can drive the No. 2 support plate 5 to slide to the left under the support of the guide rod 3. Therefore, the distance between the No. 1 support plate 2 and the No. 2 support plate 5 can be changed, and then the distance between the two roller fixing frames 6 can be adjusted and the two ends of the roller can be clamped by the roller clamping plate 7. At this time, the hand wheel at one end of the first screw rod 8 can be used to drive it to rotate. When the first screw rod 8 rotates, it will drive the two first clamping rods 9 on the roller fixing frame 6, so that the two first clamping rods 9 can clamp the front and rear sides of the roller end, and then the second screw rod 10 is driven to rotate by the hand wheel at one end of the second screw rod 10. When the second screw rod 10 rotates, it will drive the two second clamping rods 11 to slide synchronously in the opposite direction under the support of the roller fixing frame 6, so that the two second clamping rods 11 can clamp the top and bottom of the roller end, thereby avoiding the movement of the roller, and can clamp and fix the roller ends of different specifications. Finally, one of the roller fixing frames 6 is driven to rotate by an external motor to make the roller rotate continuously in the heat treatment box, thereby evenly heating the roller.
