Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0031] The directional terms or positional relationships such as "up," "down," "left," and "right" used in the embodiments are based on the drawings in this utility model specification. Figure 1 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0032] like Figures 1-4 As shown, in this embodiment, the distance between the first set of support seats and the second set of support seats is adjustable, so that the distance between the first clamping frame 6 and the second clamping frame 7 changes accordingly, thereby achieving the effect of positioning and supporting the transmission shaft after the change of the working roller spacing.

[0033] like Figure 1 , 2As shown, the embodiment includes a base plate 1, a first set of support seats and a second set of support seats arranged on the base plate 1, and a clamping frame. The first set of support seats is located at the upper position of the base plate 1, and the second set of support seats is located at the lower position of the base plate 1.

[0034] The first set of support seats includes a first support seat 2 and a second support seat 3, and the second set of support seats includes a third support seat 4 and a fourth support seat 5. Linear driving members are fixedly arranged between the first support seat 2 and the second support seat 3, and between the third support seat 4 and the fourth support seat 5. In the embodiment, two linear driving members are hydraulic cylinders 8. The axial direction of the hydraulic cylinders 8 is along the left and right directions, and the working directions of the two linear driving members are parallel, that is, the extension and retraction directions of the piston rods 81 of the two hydraulic cylinders 8 are along the left and right directions. The clamping frame is fixedly arranged at the output ends of the two linear driving members, that is, the clamping frame is fixedly arranged at the right ends of the two piston rods 81. In the embodiment, the linear driving members can also adopt any existing structure that can realize linear motion, such as air cylinders or electric cylinders. This part of the content is the same as the prior art.

[0035] There are two improvements in the embodiment:

[0036] I. The first set of support seats is slidingly arranged on the base plate 1. The sliding manner is that a first lead screw 9 and a second lead screw 10 are rotatably arranged on the base plate 1. The first lead screw 9 and the second lead screw 10 are arranged on the base plate 1 through a lead screw seat, and are rotatably connected to the lead screw seat through bearings. The axial directions of the first lead screw 9 and the second lead screw 10 are perpendicular to the line connecting the third support seat 4 and the fourth support seat 5, that is, the axial directions of the first lead screw 9 and the second lead screw 10 are arranged along the up and down directions. A first lead screw nut 11 is sleeved on the first lead screw 9, and the first lead screw nut 11 is fixedly connected to the first support seat 2. A second lead screw nut 12 is sleeved on the second lead screw 10, and the second lead screw nut 12 is fixedly connected to the second support seat 3. A power member is fixedly arranged on the base plate 1 to drive the first lead screw 9 and the second lead screw 10 to rotate. The power member includes a first power member and a second power member. In the embodiment, the first power member and the second power member are electric motors 13 in the prior art. In order to ensure the stability of the electric motors 13, a fixed plate 16 is fixedly arranged on the base plate 1, and the first power member and the second power member are fixedly arranged on the fixed plate 16. The first lead screw 9 and the second lead screw 10 are connected to the output ends of the power member, that is, the output end of the first power member penetrates through the fixed plate 16 and is connected to the first lead screw 9, and the output end of the second power member penetrates through the fixed plate 16 and is connected to the second lead screw 10. Of course, the power member in the embodiment can also adopt a worm gear structure in the prior art, as long as it can realize the rotation of the first lead screw 9 and the second lead screw 10.

[0037] As shown in FIG. 1, the first support seat 2 and the second support seat 3 are arranged on the base plate 1 through the first lead screw 9 and the second lead screw 10. The first support seat 2 is fixedly connected to the first lead screw nut 11, and the second support seat 3 is fixedly connected to the second lead screw nut 12. The third support seat 4 and the fourth support seat 5 are arranged on the base plate 1 through the hydraulic cylinders 8. The third support seat 4 is fixedly connected to the piston rod 81 of the hydraulic cylinder 8 on the left, and the fourth support seat 5 is fixedly connected to the piston rod 81 of the hydraulic cylinder 8 on the right. Figure 1 , 2As shown, the bottom plate 1 is provided with a first sliding rail 14 and a second sliding rail 15, the length direction of the first sliding rail 14 and the second sliding rail 15 is along the axial direction of the first screw rod 9, and the length direction in this embodiment refers to the distance in the up-down direction. The first support base 2 is provided with a groove matched with the first sliding rail 14, and the second support base 3 is provided with a groove matched with the second sliding rail 15. Here, matched refers that the first support base 2 can be clamped on the first sliding rail 14 through the groove and cannot fall off and can move up and down along the first sliding rail 14, and the second support base 3 is the same. The first support base 2 moves linearly along the first sliding rail 14, and the second support base 3 moves linearly along the second sliding rail 15. When the first screw rod 9 and the second screw rod 10 rotate, the first support base 2, the second support base 3 and the hydraulic cylinder 8 have a tendency to rotate. At this time, the first sliding rail 14 and the second sliding rail 15 can limit the first support base 2, the second support base 3 and the hydraulic cylinder 8 from rotating. Therefore, under the thread cooperation of the first screw rod nut 11 and the first screw rod 9 and the second screw rod nut 12 and the second screw rod 10, the first support base 2, the second support base 3 and the hydraulic cylinder 8 move linearly in the up-down direction, that is, the second group of support bases are fixed on the bottom plate 1, and the first group of support bases slide towards the second group of support bases or away from the second group of support bases.

[0038] II. As shown in Figure 1 , 2 The clamping frame includes a first clamping frame 6 and a second clamping frame 7 which are independent of each other. The structures of the first clamping frame 6 and the second clamping frame 7 are the same as those of the prior art, and the difference lies in that the integral structure in the prior art is improved into a split structure. The first clamping frame 6 is fixed on the output end of the linear driving member between the first support base 2 and the second support base 3, that is, the first clamping frame 6 is fixed on the right end of the hydraulic cylinder 8 at the upper position. The second clamping frame 7 is fixed on the output end of the linear driving member between the third support base 4 and the fourth support base 5, that is, the second clamping frame 7 is fixed on the right end of the hydraulic cylinder 8 at the lower position. When the first group of support bases slide towards or away from the second group of support bases, the first clamping frame 6 moves towards or away from the second clamping frame 7.

[0039] In order to ensure the stability of the movement of the first clamping frame 6, a limiting column 17 is fixed on the side of the second clamping frame 7 facing the first clamping frame 6, and the axial direction of the limiting column 17 is along the axial direction of the first screw rod 9. A limiting groove 18 is provided on the first clamping frame 6 for the insertion or extraction of the limiting column 17, and the shape and size of the limiting groove 18 are matched with those of the limiting column 17. Here, matched refers that the shape of the limiting groove 18 is also cylindrical, and the length of the limiting groove 18 is greater than or equal to the length of the limiting column 17. When the first clamping frame 6 moves up and down, the limiting column 17 is always located in the limiting groove 18, thereby ensuring the stability of the movement.

[0040] Further, one side of the second clamping frame 7 towards the first clamping frame 6 is also fixedly provided with a sliding block 19. In this embodiment, the sliding block 19 is a square block, and the axial direction of the sliding block 19 is arranged along the axial direction of the first lead screw 9. The first clamping frame 6 is provided with a sliding groove 20 for inserting or pulling out the sliding block 19. The shape and size of the sliding groove 20 are matched with the sliding block 19. Here, the shape of the sliding groove 20 is also square, and the length of the sliding groove 20 is greater than or equal to the length of the sliding block 19. When the first clamping frame 6 moves up and down, the sliding block 19 is always located in the sliding groove 20. The sliding block 19 and the limiting column 17 double guarantee the stability of the movement of the first clamping frame 6.

[0041] Working principle: the motor 13 rotates to drive the first lead screw 9 and the second lead screw 10 to rotate, and the first support seat 2 and the second support seat 3 move up and down, and the first clamping frame 6 moves up and down, thereby changing the distance between the first clamping frame 6 and the second clamping frame 7, and achieving the effect of positioning and supporting the transmission shaft after the distance between the work rollers changes.

[0042] This embodiment also includes a supporting assembly, a clamping jaw 25 and a measuring scale 27.

[0043] As shown in Figure 1 , 2 , the supporting assembly is arranged on the bottom plate 1. The supporting assembly includes a support rod 21, a connecting shaft 22, a sliding rod 23 and a connecting block 24. The support rod 21 is arranged on the bottom plate 1. In this embodiment, the left end of the support rod 21 is hingedly arranged on the bottom plate 1. The hinging manner is the prior art, which will not be described in detail here. The connecting shaft 22 is fixedly arranged at one end of the support rod 21 close to the second clamping frame 7 (i.e. the right end of the support rod 21). The sliding rod 23 is slidingly arranged on one side of the connecting shaft 22 towards the second clamping frame 7 (i.e. the right end surface of the connecting shaft 22). In this embodiment, the connecting shaft 22 is provided with a sliding groove extending in the left-right direction, and the sliding rod 23 is sleeved in the sliding groove and can slide left and right relative to the connecting shaft 22. The connecting block 24 is fixedly arranged on the second clamping frame 7 at a position corresponding to the sliding rod 23, and the connecting block 24 is fixedly connected with the end of the sliding rod 23. The axial direction of the support rod 21 and the sliding direction of the sliding rod 23 are both parallel to the working direction of the linear driving member, i.e. the axial direction of the support rod 21 and the sliding direction of the sliding rod 23 are both in the left-right direction. The supporting assembly is used to support the second clamping frame 7 to improve the stability of the second clamping frame 7. When the hydraulic cylinder 8 drives the second clamping frame 7 to move left and right, the sliding rod 23 will also move left and right in the connecting shaft 22, without hindering the movement of the second clamping frame 7.

[0044] As shown in Figure 1 , 2As shown in the drawings, the first clamping frame 6 is detachably provided with a claw 25 at the end away from the first set of support seats (i.e. the right end of the first clamping frame 6), and the second clamping frame 7 is detachably provided with a claw 25 at the end away from the second set of support seats (i.e. the right end of the second clamping frame 7), and there are a total of four claws 25, as shown in Figure 3 、 4 As shown in the drawings, the first clamping frame 6 and the second clamping frame 7 are provided with a strip-shaped slot 26, and the claw 25 is fixedly provided with a fixed block 251, and the fixed block 251 is slidingly arranged in the strip-shaped slot 26, and the first clamping frame 6 and the claw 25 and the second clamping frame 7 and the claw 25 are detachably connected by a fastener. The structure and adjustment mode of the claw 25 are prior art, and this embodiment will not be described in detail.

[0045] As shown in the drawings, Figure 1 、 2 The bottom plate 1 is also fixedly provided with a measuring scale 27, which extends along the working direction of the linear drive, i.e. the measuring scale 27 extends in the left and right directions, and the measuring scale 27 is fixedly arranged on the second clamping frame 7, and the measuring scale 27 is not fixed between the third support seat 4 and the fourth support seat 5, and the measuring scale 27 is used to observe the advancing distance of the first clamping frame 6 and the second clamping frame 7 in the left and right directions. Of course, the measuring scale 27 can also be fixedly arranged on the first clamping frame 6, and the same effect can be achieved.
