Abstract
Description
Technical Field

[0002] Hot-rolled strip steel is an important steel product, which has a great impact on the technological progress and economic benefits of the entire steel industry. The finishing mill of the 1580 hot rolling line in Bayuquan of Anshan Iron and Steel Co., Ltd. is equipped with hydraulic looping devices between the F1-F7 stands. It keeps the strip steel at a relatively constant tension and looping amount, detects and adjusts the speed deviation caused by various disturbances, and ensures the rolling stability of the hot-rolled strip steel in the finishing mill. The looping device ensures that during the rolling process, a preset tension is generated between the stands for the strip steel, forming a buffer zone between the two stands to ensure the continuous rolling of each stand.
[0003] The angle of the looper is detected by the encoder, which is installed on the working side of the finishing mill and connected to the looper cylinder pin. Due to the small space at this location, it is impossible to use a dial indicator for alignment. The coaxiality between the looper cylinder pin and the encoder coupling shaft is not good, that is, the different points of the measured axis to the reference axis may appear in all directions in space, and the tolerance value is greater than 0.01mm. Often due to poor installation accuracy, the encoder shaft end coupling is damaged, resulting in problems with angle feedback, affecting rolling stability and even jamming. Therefore, special tools need to be made to ensure coaxiality. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a special tool for encoder installation and alignment, including a mounting seat 1, a coupling 2 is plugged into the rear end of the mounting seat 1, the coupling 2 can be installed on the sleeve cylinder pin shaft, and an encoder 3 is plugged into the front end of the mounting seat 1. The coupling 2 and the encoder 3 are prior art and can be implemented by technicians in this field. Since it is prior art, it will not be described in detail in this case. A block 4 is fixedly connected to the inner wall of the mounting seat 1, and the block 4 can block the encoder 3. When the encoder 3 and the block 4 are in contact, the rotation is stopped. A positioning component is arranged inside the mounting seat 1 for positioning the encoder 3 to ensure that the encoder 3 is centered and can facilitate alignment. An anti-loosening component is arranged inside the mounting seat 1 to prevent the encoder 3 from being offset during installation due to accidental touch, thereby ensuring stability.
[0031] Reference Figure 1 , Figure 3 , Figure 4The positioning assembly includes a moving ring 54, a moving block 52 is fixedly connected to the front surface of the moving ring 54, a T-shaped block 53 is fixedly connected to the lower surface of the moving block 52, a positioning block 51 is slidably connected to the inner wall of the mounting seat 1, and a T-shaped slot 501 is provided on the upper surface of the positioning block 51. The moving block 52, the T-shaped block 53, the positioning block 51 and the T-shaped slot 501 are all provided with multiple groups, forming a circular array with the center line of the moving ring 54, and the encoder 3 can be clamped from multiple directions to be centered. A screw 56 is penetrated and threadedly connected to the front surface of the moving ring 54. When the screw 56 rotates, it can drive the moving ring 54 to move, and a knob 55 is fixedly connected to the front surface of the screw 56.
[0032] Reference Figure 1 , Figure 3 , Figure 4 The anti-loosening component includes a slot 601, the inner wall of the mounting seat 1 is elastically connected with an L-shaped block 61 through a compression spring 62, the right surface of the L-shaped block 61 is fixedly connected with a block 63, and the slot 601 and the block 63 fit together.
[0033] Reference Figure 1 , Figure 3 , Figure 4 The moving ring 54 is slidably connected to the inner wall of the mounting seat 1 and slides in the front-to-back direction. The rear end of the upper surface of the positioning block 51 is set as an inclined surface. The T-shaped slot 501 is opened at the inclined surface of the upper surface of the positioning block 51. The T-shaped block 53 is slidably connected to the inner wall of the T-shaped slot 501. The T-shaped block 53 will move synchronously with the movement of the moving ring 54 and the moving block 52. When the T-shaped block 53 moves, it will squeeze the T-shaped slot 501 to drive the surrounding positioning blocks 51 to open or contract synchronously. The screw 56 penetrates and is rotatably connected to the front surface of the mounting seat 1.
[0034] Reference Figure 1 , Figure 3 , Figure 4 The slot 601 is opened on the left surface of the screw rod 56, and the block 63 is inserted into the inner wall of the slot 601. The right end of the upper surface of the block 63 is set as an arc surface. By squeezing the arc surface of the block 63, the block 63 will move to the left. When the screw rod 56 rotates forward, it will squeeze the arc surface of the block 63. The L-shaped block 61 is set as an L-shape, one end of the compression spring 62 is fixedly connected to the left surface of the L-shaped block 61, and the other end of the compression spring 62 is fixedly connected to the inner wall on the left side of the L-shaped block 61. The L-shaped block 61 passes through and is slidably connected to the front surface of the mounting seat 1. When the L-shaped block 61 moves to the left, it will squeeze the compression spring 62 to generate a reaction force.
[0035] Working principle: When using this device, first install the coupling 2 on the sleeve cylinder pin shaft, then sleeve the mounting base 1 on the outer wall of the coupling 2, and insert the encoder 3 into the other side of the mounting base 1. When the coupling 2 and the encoder 3 are in contact, stop moving, and then rotate the encoder 3 until the edge of the encoder 3 contacts the stop block 4 and stops rotating.
[0036] At this time, turning the knob 55 drives the screw 56 to rotate, and drives the moving ring 54 to move forward. The moving ring 54 moving forward will drive the T-block 53 to move forward, and the T-block 53 moving forward will squeeze the T-slot 501, thereby driving the surrounding positioning blocks 51 to synchronously contract and squeeze the encoder 3 to make it centered. When the encoder 3 is clamped, the centers of the mounting seat 1, coupling 2, encoder 3 and the sleeve cylinder pin will be aligned. At this time, the encoder 3 and the coupling 2 can be fixed on the sleeve cylinder pin. After the fixing is completed, the mounting seat 1 needs to be disassembled. When the screw 56 rotates, it will squeeze the arc surface of the block 63 to make it move to the left, so the block 63 will not limit the screw 56.
[0037] During disassembly, the L-shaped block 61 moves leftward to drive the clamping block 63 to move leftward. The clamping block 63 moving leftward will disengage from the clamping slot 601 to release the limit on the screw 56. The L-shaped block 61 moving leftward will squeeze the compression spring 62 to generate a reaction force. After the limit of the screw 56 is released, the knob 55 is rotated in the opposite direction to drive the screw 56 to reverse, thereby driving the moving ring 54, the moving block 52 and the T-shaped block 53 to move backward. The T-shaped block 53 moving backward will squeeze the T-slot 501 to drive the surrounding positioning blocks 51 to open synchronously to release the clamping of the encoder 3, and then the mounting base 1 is removed and the L-shaped block 61 is released.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
