Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, in particular to an anti-deviating device for installing a bearing base of a belt conveyor driving roller. Background Art

[0002] Belt conveyor is a kind of material transportation equipment widely used in mining, coal, food and other industries. It can continuously transport materials from one place to another through the conveyor belt. It has the advantages of high efficiency and low energy consumption. The motor transmits power to the transmission belt through the driving roller, and then transports objects through the transmission belt. When the driving roller transmits power, in order to reduce the friction when the driving roller rotates, a self-aligning bearing will be installed on the driving roller to reduce the friction when the driving roller rotates.

[0003] Before installing the driving roller of the belt conveyor, it is necessary to first install the self-aligning bearing on the shaft of the driving roller, and then install the driving roller and the machine head shell. At this time, it is necessary to first place the machine head shell vertically upward, and then lift the driving roller carrying the self-aligning bearing vertically, and realize the installation with the machine head shell by moving the driving roller downward. When the driving roller carries the self-aligning bearing and is installed in the installation bottom hole in the machine head shell, a point or surface of the self-aligning bearing installed on the outer surface of the driving roller touches the edge of the bottom hole first, and the self-aligning bearing will be offset, resulting in the outer ring of the self-aligning bearing and the bottom hole of the machine head shell not being concentric, and then causing the self-aligning bearing to fail to be installed. At this time, it is necessary to lift the driving roller again, and make the outer ring axis of the self-aligning bearing coaxial with the axis of the driving roller by knocking before installing it. However, during the installation process, since the driving roller is installed by hoisting, it is inconvenient to control the descending position when the driving roller moves down, and the outer ring of the bearing is easy to contact with the edge of the bottom hole, which results in a single installation requiring multiple hammering adjustments, resulting in inconvenience in installation.

[0004] In view of the above problems, the prior art provides some solutions. For example, a self-aligning bearing hoisting and hoisting method for a fan with publication number CN103058043B adjusts and locks the horizontal state of the inner ring by rotating the pressure plate screw, thereby achieving the purpose of easy installation. However, when installing large equipment, the outer ring of the bearing needs to be accurately installed in the mounting hole. The outer surface of the outer ring is adjusted by screws. Although the horizontality of the outer ring and the inner ring can be locked, the exposed part of the screw will make it inconvenient to dock the outer ring of the bearing with the mounting bottom hole. When docking the outer ring of the bearing, the screw part also needs to be docked, which increases the difficulty of installation and causes inconvenience in installation.

[0005] Therefore, an anti-deviating device for installing a bearing base of a belt conveyor driving roller is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-deviation device for installing a belt conveyor drive roller bearing base, which solves the problem that the self-aligning bearing cannot be installed due to the force deviation of the outer ring of the self-aligning bearing when installing the self-aligning bearing. The outer ring of the self-aligning bearing and the roller main shaft are relatively fixed and then the roller main shaft and the installation bottom hole are connected, thereby achieving the purpose of preventing the bearing base from deviating during the installation process.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An anti-deviating device for installing a belt conveyor drive roller bearing base comprises a positioning circular plate, the positioning circular plate is fitted on the front end of a shaft to be installed, a self-aligning bearing to be fixed is installed on the surface of the shaft, the self-aligning bearing comprises an inner ring, a roller and an outer ring connected in sequence from the inside to the outside, and also comprises a clamping claw, a turning handle, an adjusting disk, a locking assembly, a locking block, an outer disk, a sliding disk, a telescopic assembly and a positioning small plate, the clamping claw is arranged in a circular array on the surface of the positioning circular plate, the turning handle is connected to the front end of the positioning circular plate, the adjusting disk is sleeved on the turning handle, and the locking assembly is connected between the positioning circular plate and the adjusting disk. The locking block is connected to the outer wall of the turning handle and is located at the front end of the adjusting disk, the outer disk is connected to the outer edge of the positioning circular plate, the sliding disk is connected to the outer edge of the outer disk, the telescopic assembly is connected to the outer edge of the sliding disk, and the positioning small plate is connected to the rear end of the telescopic assembly. The rear end surface of the positioning circular plate is the reference surface, and the rear end surface of the positioning small plate is the secondary surface parallel to the reference surface. When the telescopic assembly rotates, the covering position of the secondary surface is radially adjusted, and the sliding disk drives the secondary surface to gradually move backward in a spiral shape along the axis of the outer disk while keeping it parallel to the reference surface through the telescopic assembly.

[0009] Through the above scheme, the rear end face of the positioning circular plate is parallel to the rear end face of the positioning small plate, and the front end face of the outer ring is parallel to the front end of the shaft rod. The front end face of the outer ring is limited by multiple positioning small plates, so that the multiple positioning small plates support the front end face of the outer ring when the outer ring is subjected to force, thereby avoiding the outer ring axis from deviating from the shaft rod axis, thereby facilitating the installation of the outer ring.

[0010] Preferably, the turning handle includes a handle, a pin block and a threaded section, the handle is connected to the front end of the positioning circular plate, the pin block is sleeved on the outer wall of the handle, the adjusting disk is sleeved on the outer wall of the pin block, the threaded section is arranged on the outer wall of the handle and located at the front end of the pin block, the threaded section is connected to the locking block, and the distance value between the front and rear ends of the pin block is greater than the distance value between the front and rear ends of the adjusting disk.

[0011] Through the above scheme, the distance between the front and rear ends of the pin block is greater than the distance between the front and rear ends of the adjusting disk. Therefore, when the locking block rotates and moves backward along the threaded section to squeeze the pin block, the rear end of the pin block can extend out of the adjusting disk, thereby facilitating the adjustment of the locking assembly through the pin block.

[0012] Preferably, a limit strip is provided in the middle of the outer surface of the handle, the limit strip is clamped with the pin block, a limit block is provided on the outer surface of the pin block, the limit block is clamped with the adjustment disk, and the front end of the pin block has magnetic force.

[0013] Through the above scheme, the pin block can only move forward and backward on the outer wall of the handle, and then the pin block will be driven to move when the handle is rotated. Similarly, the adjusting disk can only move forward and backward on the surface of the pin block, and then the adjusting disk can be driven to rotate when the pin block is rotated. By making the front end of the pin block have magnetic force, the pin block can fit with the locking block.

[0014] Preferably, rectangular limiting grooves are provided at equal angles on the surface of the positioning circular plate, the clamp comprises a slider, a slide rod and a claw body, the slider is connected in the limiting groove, the slide rod and the claw body are respectively connected to the front and rear ends of the slider, an adjustment groove is provided on the surface of the adjustment disk, the adjustment groove is arc-shaped, and the slide rod extends into the adjustment groove.

[0015] Through the above scheme, the adjustment slot can be driven to rotate by rotating the adjustment disk. The adjustment slot is arc-shaped, and when the adjustment slot rotates, the slide rod can be driven to slide along the limit slot, so that the claw body and the shaft rod are fitted to achieve the purpose of fixing the positioning circular plate.

[0016] Preferably, the locking assembly includes a slide plate, a spring, a gasket and a snap ring, the slide plate array is connected to the front end of the positioning circular plate, one end of the spring is connected to the end of the slide plate close to the handle, a collar is connected to the center of the front end of the positioning circular plate, the other end of the spring is connected to the outer surface of the collar, the gasket is connected to the end of the slide plate away from the handle, the snap ring is connected to the rear end of the pin block, the inner diameter of the snap ring is greater than the outer diameter of the collar, and when the spring is not under pressure, the distance from the outer wall of the collar to the outside of the gasket is greater than the distance from the outer wall of the collar to the inner wall of the sliding disk.

[0017] Through the above scheme, the movement of the pin block will drive the movement of the retaining ring, and the movement of the retaining ring can pressurize the spring leaf, causing the spring leaf to bend, and the distance between the two ends of the bent spring leaf is shortened, so that the slide plate drives the gasket to separate from the inner wall of the sliding disk, thereby achieving the purpose of releasing the lock of the sliding disk.

[0018] Preferably, the gasket is made of rubber material, the end of the gasket away from the skateboard is wavy, and the distance between the front and rear ends of the gasket is equal to the distance between the front and rear ends of the outer sleeve.

[0019] Through the above scheme, the gasket is made of rubber material with greater friction, thereby effectively preventing the rotation of the ring. The distance between the front and rear ends of the gasket is equal to the distance between the front and rear ends of the outer disc, so that the sliding disc can always be in contact with the gasket when moving on the surface of the outer disc, thereby facilitating pre-adjustment of the device and effectively reducing the time for fixing the self-aligning bearing.

[0020] Preferably, the telescopic assembly includes a turntable, a block, a limit frame, a slide, a slot, a spring and a screw. The turntable is connected to the outer surface of the slide, the block and the limit frame are connected to the outer surface of the turntable in an array, the slide is connected to the inner cavity of the limit frame, the block is claw-tip shaped, a slot is provided at the front end of the slide, one end of the spring is connected to the inner wall of the slot, the other end of the spring is connected to the limit frame, the outer surface of the turntable is connected to a screw, and the positioning plate is connected to the rear end of the slide.

[0021] Through the above scheme, by making the card block claw-shaped, the distance between the two sides of the card block gradually increases, and then in the process of the turntable driving the card block to rotate, the slide will be squeezed by the pressure block to move, thereby achieving the purpose of adjusting the slide position.

[0022] Preferably, the diameter of the locking block is greater than the diameter of the pin block, and the rear end of the locking block is frosted.

[0023] Through the above scheme, the diameter value of the locking block is greater than the diameter value of the pin block, and then when the locking block drives the pin block to move to the specified position, it will contact the front end of the adjusting disk, thereby achieving the purpose of fixing the position of the adjusting disk by squeezing. The rear end of the locking block is frosted to increase the roughness, which can effectively increase the friction between the locking block and the pin block and the adjusting disk, thereby effectively improving the locking effect.

[0024] Preferably, the claw body has an arc-shaped side close to the shaft rod, and an array of notches is formed on the inner wall of the claw body.

[0025] Through the above scheme, the side of the clamping jaw close to the shaft rod is arc-shaped, thereby increasing the contact area between the clamping jaw and the shaft rod, increasing the friction coefficient between the clamping jaw and shaft rods of different sizes, and improving the stability of the connection between the clamping jaw and the shaft rod.

[0026] Preferably, the lower surfaces of the plurality of positioning small plates are in the same plane, and the positioning small plates are parallel to the lower surface of the positioning circular plate.

[0027] Through the above scheme, a plane is determined by multiple positioning plates, so that one side of the outer ring is parallel to the plane formed by the multiple positioning plates, and the outer ring is parallel to one side of the shaft rod, thereby ensuring that the outer ring and the shaft rod are coaxial, achieving the purpose of easy installation.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention solves the problem that the self-aligning bearing cannot be installed due to the force offset of the outer ring of the self-aligning bearing during installation. By arranging a positioning small plate and a positioning circular plate, the positioning small plate is parallel to the rear end face of the positioning circular plate. During installation, the rear end faces of the positioning circular plate and the positioning small plate are respectively fitted with the front end face of the outer ring of the shaft rod. When the outer ring is subjected to force, the positioning small plate will give support force to the outer ring, thereby achieving the purpose of facilitating the docking of the outer ring. At the same time, by arranging clamping claws and telescopic components, it is convenient to dock shaft rods and outer rings of different sizes, thereby achieving the purpose of facilitating installation.

[0030] 2. By setting a locking component, when the spring leaf is open, the gasket will fit on the sliding disk, thereby locking the position of the sliding disk. By locking the position of the sliding disk, the positioning circular plate can be limited by the slide frame, thereby achieving the purpose of facilitating the rotation of the adjustment disk. After the sliding disk is unlocked, the sliding disk can be rotated to make the sliding disk drive the positioning small plate to gradually move backward along the spiral line, so that the positioning small plate will squeeze the inclined outer ring during the backward movement, so that the axis of the outer ring gradually coincides with the axis of the shaft rod, thereby reducing the adjustment time of the outer ring, achieving the purpose of facilitating the adjustment of the state of the self-aligning bearing, and then achieving the purpose of facilitating the installation of the self-aligning bearing.

[0031] 3. By setting the clamping jaws, when the adjusting disk is rotated, the clamping jaws can be moved along the adjusting groove and the limit groove, so that the clamping jaws are close to the shaft rod, and the turntable is rotated so that the clamping block can squeeze the slide to move in the limit frame, and then the position of the slide is adjusted, so that the slide drives the positioning plate to move outward, thereby achieving the purpose of adjusting the position of the positioning plate to adapt to different outer ring sizes, and thus facilitating the installation of different self-aligning bearings.

[0045] By setting the positioning plate 10 and the positioning circular plate 1, the rear end face of the positioning circular plate 1 is parallel to the rear end face of the positioning plate 10, and by making the positioning circular plate 1 and the positioning plate 10 contact with the front end face of the shaft rod a and the front end face of the outer ring b3 respectively, the front end face of the shaft rod a can be kept parallel to the front end face of the outer ring b3, and the front end face of the outer ring b3 is limited by multiple positioning plates 10, so that the front end face of the outer ring b3 is supported by multiple positioning plates 10 when the outer ring b3 is subjected to force, thereby avoiding the deviation of the axis of the outer ring b3 from the axis of the shaft rod a, thereby facilitating the installation of the outer ring b3.

[0046] As an embodiment of the present invention, refer to Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9The turning handle 3 includes a handle 301, a pin block 302 and a threaded section 303. The handle 301 is connected to the front end of the positioning circular plate 1. The handle 301 is rotatably connected to the positioning circular plate 1. The pin block 302 is sleeved on the outer wall of the handle 301. The adjusting disk 4 is sleeved on the outer wall of the pin block 302. The threaded section 303 is arranged on the outer wall of the handle 301 and located at the front end of the pin block 302. The threaded section 303 is connected to the locking block 6. The locking block 6 is threadedly connected to the threaded section 303, so that the locking block 6 is relatively larger than the handle 3. When the handle 301 is rotated, the locking block 6 moves forward and backward on the surface of the handle 301, and the distance between the front and rear ends of the pin block 302 is greater than the distance between the front and rear ends of the adjusting disk 4. When the rear end of the locking block 6 is in contact with the adjusting disk 4, the rear end of the pin block 302 can extend out of the adjusting disk 4, thereby realizing the adjustment of the locking component 5. A limit strip 3011 is provided in the middle of the outer surface of the handle 301, and the limit strip 3011 is engaged with the pin block 302. The limit strip 3011 allows the pin block 302 to move forward and backward on the surface of the handle 301. The outer surface of the block 302 is provided with a limit block 3021, and the limit block 3021 is clamped with the adjustment disk 4. The limit block 3021 allows the pin block 302 to slide back and forth in the adjustment disk 4. The front end of the pin block 302 has a magnetic force and can be adsorbed with the locking block 6. Then, when the locking block 6 moves forward, the locking block 6 can drive the pin block 302 to move forward and release the squeezing of the spring leaf 502. The surface of the positioning circular plate 1 is provided with rectangular limit grooves 101 at equal angles. The clamping jaw 2 includes a slider 201, a slide rod 202 and a claw The slider 201 is connected to the limit groove 101, and the slider 201 slides in the limit groove 101. The slide bar 202 and the claw body 203 are respectively connected to the front and rear ends of the slider 201. The surface of the adjusting disk 4 is provided with an adjusting groove 401. The limit groove 101 and the adjusting groove 401 keep a partial overlap. The adjusting groove 401 is arc-shaped. The slide bar 202 extends into the adjusting groove 401. When the adjusting disk 4 rotates, the clamping claw 2 can be driven to slide in the limit groove 101 through the adjusting groove 401.

[0047] By setting the turning handle 3, the rotation of the handle 301 will drive the adjusting disk 4 to rotate through the pin block 302, and then adjust the angle between the adjusting disk 4 and the positioning circular plate 1, so that the clamping claw 2 limited by the limiting groove 101 and the rectangular groove slides toward the side of the handle 301, so as to facilitate the fit with the shaft a, so as to achieve the purpose of fixing the device and the shaft a, and at the same time, by rotating the locking block 6, the locking block 6 moves backward along the surface of the handle 301, and the locking block 6 will squeeze the pin block 302 to move backward, so that the pin block 302 adjusts the locking assembly 5.

[0048] As an embodiment of the present invention, refer to Figure 5 , Figure 8 and Fig. 9The locking assembly 5 includes a slide plate 501, a spring 502, a gasket 503 and a snap ring 504. The slide plates 501 are connected in an array to the front end of the positioning circular plate 1. The slide plates 501 are in an "L" shape. The slide plates 501 are slidably connected to the positioning circular plate 1. The slide plates 501 are slidably connected to the outer sleeve disc 7. One end of the spring 502 is connected to the end of the slide plate 501 close to the handle 301. The center of the front end of the positioning circular plate 1 is connected to the collar 102. The other end of the spring 502 is connected to the collar 102. On the outer surface of the ring 102, there is a gap between the rear end of the spring 502 and the positioning circular plate 1, so that when the spring 502 is compressed, the compressed part of the spring 502 can bend backward. The gasket 503 is connected to the end of the slide plate 501 away from the handle 301, and the snap ring 504 is connected to the rear end of the pin block 302. The movement of the pin block 302 will drive the snap ring 504 to move, and the movement of the snap ring 504 will squeeze the spring 502, so that the spring 502 is bent. The inner diameter value of the snap ring 504 is large. The outer diameter of the collar 102 is greater than that of the outer diameter of the collar 102, and when the clamping ring 504 squeezes the spring sheet 502 to deform, the spring sheet 502 can be given bending space. When the spring sheet 502 is not compressed, the distance from the outer wall of the collar 102 to the outer side of the gasket 503 is greater than the distance from the outer wall of the collar 102 to the inner wall of the sliding plate 8. When the spring sheet 502 is not bent, the spring sheet 502 pushes the gasket 503 to be squeezed on the sliding plate 8 through the slide plate 501, thereby realizing the limiting of the sliding plate 8. The gasket 503 is made of rubber material. The rubber has a good fitting effect, and can be fitted on the sliding plate 8, so that the sliding plate 8 and the outer disc 7 are relatively fixed. The end of the gasket 503 away from the slide plate 501 is wavy, which effectively increases the friction between the gasket 503 and the sliding plate 8. The distance value between the front and rear ends of the gasket 503 is equal to the distance value between the front and rear ends of the outer disc 7, so that the gasket 503 has a sufficient length, and when the sliding plate 8 moves to any position on the surface of the outer disc 7, the sliding plate 8 can be limited.

[0049] By setting the locking assembly 5, the sliding plate 8 and the outer disc 7 can be relatively fixed, so that when the clamping jaws 2 are adjusted, the position of the outer disc 7 can be fixed. Through the retaining ring 504, when the locking block 6 moves, pressure can be generated on the spring leaf 502, so that the spring leaf 502 is bent. The bent spring leaf 502 allows the slide plate 501 to drive the gasket 503 to separate from the sliding plate 8, thereby achieving the purpose of contact locking of the sliding plate 8.

[0050] As an embodiment of the present invention, refer to Figure 7 , Figure 8 and Fig. 9The telescopic assembly 9 includes a turntable 901, a block 902, a limit frame 903, a slide 904, a slot 905, a spring 906 and a screw 907. The turntable 901 is connected to the outer surface of the slide 8, and the turntable 901 can rotate on the outer surface of the slide 8. The block 902 is connected to the outer surface of the turntable 901 in an array, and the limit frame 903 is connected to the outer surface of the slide 8 in an array. The slide 904 is connected to the inner cavity of the limit frame 903. The block 902 is in a claw tip shape. By rotating the block 902, the slide 904 can be squeezed so that the slide 904 is in the limit frame 903. The slide 904 is gradually extended to achieve the purpose of adjusting the distance between the positioning plate 10 and the shaft rod a. A slot 905 is provided at the front end of the slide 904, one end of the spring 906 is connected to the inner wall of the slot 905, and the other end of the spring 906 is connected to the limit frame 903. When the block 902 gradually squeezes the slide 904 to move outward, the spring 906 is compressed and contracted, so that the slide 904 fits on the block 902. The outer surface of the turntable 901 is connected with a screw 907, and the position between the turntable 901 and the slide 8 can be locked by the screw 907, so as to achieve the squeezing degree of the block 902 on the slide 904, and the limit The purpose of extending the length of the positioning slide 904 is that the positioning plate 10 is connected to the rear end of the slide 904, the angle between the positioning plate 10 and the slide 904 is 90 degrees, and the slide 904 is in an "L" shape bent at 90 degrees. The diameter value of the locking block 6 is greater than the diameter value of the pin block 302, and then when the locking block 6 squeezes the pin block 302 to move backward, it can fit with the adjustment disk 4, and then squeeze the adjustment disk 4 to limit the position, and the rear end of the locking block 6 is frosted. The frosting can effectively increase the roughness of the rear end of the locking block 6, thereby increasing the friction coefficient and reducing the position of the fixed adjustment disk 4 and the positioning circular plate 1. , adjusting the relative rotation of the disk 4, the side of the claw body 203 close to the shaft a is arc-shaped, and the arc-shaped setting makes a single clamping jaw 2 have two contact points when contacting the shaft a, thereby effectively improving the connection effect with the shaft a, and the inner wall array of the claw body 203 is provided with a notch 2031, and the notch 2031 is arranged horizontally. The setting of the notch 2031 increases the friction between the clamping jaw 2, and avoids the sliding of the clamping jaw 2 on the surface of the shaft a when the positioning plate 10 squeezes the outer ring b3. The lower surfaces of the multiple positioning plates 10 are in the same plane, and the positioning plate 10 is parallel to the lower surface of the positioning circular plate 1.

[0051] By setting up the telescopic component 9, the device can adapt to self-aligning bearings b of different sizes. The turntable 901 drives the block 902 to rotate, so that the block 902 squeezes the slide 904, and the slide 904 slides in the limit frame 903. The movement of the slide 904 will drive the positioning plate 10 to move, and then adjust the position of the positioning plate 10 on the self-aligning bearing b. By moving the positioning plate 10 to the outer ring b3 of the self-aligning bearing b, the positioning plate 10 can fit with the outer ring b3 of self-aligning bearings b of different sizes during the backward movement, thereby achieving the purpose of limiting the front end surface of the self-aligning bearing b, and thus facilitating the coaxiality between the axis of the outer ring b3 and the axis of the shaft a during the installation of the self-aligning bearing b.

[0052] By making the positioning plate 10 parallel to the rear end face of the positioning circular plate 1, and making the rear end face of the positioning plate 10 fit on the front end face of the outer ring b3, the rear end face of the positioning circular plate 1 fits on the front end face of the shaft a, so that the front end face of the outer ring b3 is parallel to the front end face of the shaft a. Since the inner ring b1 is installed on the surface of the shaft a and remains coaxial with the shaft a, the axis of the outer ring b3 coincides with the axis of the shaft a when they are parallel. At this time, during the installation process, the telescopic component 9 moves radially to move the positioning plate 10 to the front end face of the outer ring b3. When the outer ring b3 contacts the mounting hole, the outer ring b3 is supported axially by the telescopic component 9 on the positioning plate 10, so that the outer ring b3 can remain coaxial with the shaft a.

[0053] Before the shaft a and the self-aligning bearing b are mounted on the mounting hole, it is necessary to first fit the rear end face of the positioning circular plate 1 to the front end face of the shaft a, and then adjust the relative rotation between the adjusting disk 4 and the positioning circular plate 1, so that the clamping jaws 2 are moved toward the shaft a and fit on the shaft a, and the position of the clamping jaws 2 is locked by adjusting the locking block 6, so as to maintain the fitting state of the positioning circular plate 1 and the front end of the shaft a; specifically, when the locking block 6 does not move, the spring leaf 502 is naturally extended, so that the gasket 503 fits on the surface of the sliding plate 8, so that the position of the sliding plate 8 is fixed with the position of the outer disc 7, and then the slide 904 is fixed at this time The slide 904 locks the position of the positioning circular plate 1 through the sliding plate 8 and the outer sleeve plate 7, and the handle 301 is turned. The handle 301 drives the adjusting disk 4 to rotate through the pin block 302. The adjusting disk 4 carries the sliding rod 202 to move through the adjusting groove 401. The sliding rod 202 drives the slider 201 to move in the limiting groove 101. The movement of the slider 201 drives the claw body 203 to move. When the multiple claw bodies 203 are all fitted on the shaft a, the locking block 6 is rotated, and the locking block 6 moves backward along the threaded section 303 to squeeze the pin block 302 backward, and exerts pressure on the adjusting disk 4 to fix the relative position of the adjusting disk 4 and the positioning circular plate 1;

[0054] After the positioning circular plate 1 is fixed, it is necessary to make the rear end face of the positioning small plate 10 fit on the front end of the outer ring b3. Due to the different sizes of the outer ring b3, the position of the positioning small plate 10 is controlled by the telescopic component 9, so that the rearward projection of the positioning small plate 10 can cover the front end face of the outer ring b3, and then by rotating the sliding plate 8, the sliding plate 8 is moved backward along the axis of the outer sleeve plate 7, so that the positioning small plate 10 gradually fits on the front end face of the outer ring b3, and during the movement of the positioning small plate 10, the positioning small plate 10 can adjust the angle of the outer ring b3 that is not coaxial with the shaft a, so that the outer ring b3 is coaxial with the shaft a. Specifically, after the locking block 6 squeezes the pin block 302 to move backward, the pin block 302 squeezes the spring leaf 502 to make the spring leaf 502 bend. After the spring leaf 502 bends, the distance between the two ends is shortened, thereby making The washer 503 is separated from the sliding plate 8, and the sliding plate 8 can rotate freely at this time. The lock of the rotating plate 901 is released by the screw 907. The rotating plate 901 drives the block 902 to squeeze the slide 904, so that the slide 904 drives the positioning plate 10 to gradually extend, so as to achieve the purpose of adjusting the position of the positioning plate 10. After the adjustment, the position of the sliding plate 8 is locked by the screw 907. At this time, the sliding plate 8 is rotated, and the sliding plate 8 drives the positioning plate 10 to move backward along the axis of the outer sleeve 7 through the limit frame 903 and the slide 904, and in the process of the positioning plate 10 gradually moving backward, the inclined outer ring b3 is squeezed to adjust the angle of the outer ring b3, and the positioning plate 10 is rotated until the sliding plate 8 cannot rotate. At this time, the outer ring b3 is fitted with the positioning plate 10, and then the front end face of the outer ring b3 is parallel to the front end face of the shaft a.

[0055] At this time, the shaft a is installed again. When the outer ring b3 is subjected to external force, the slide 904 supports the outer ring b3 through the positioning plate 10, and the outer ring b3 cannot rotate. Therefore, when the outer ring b3 is subjected to external force, it can remain coaxial with the shaft a, which is convenient for installation.

[0056] After the shaft a is installed, the locking block 6 is rotated to release the locking of the positioning circular plate 1 and the adjusting disk 4, and then the adjusting disk 4 is rotated by the handle 301 to separate the clamping jaws 2 from the shaft a, thereby disassembling the device.

[0057] Although the embodiments of the present invention have been described, it will be apparent to those skilled in the art that changes and modifications may be made to the embodiments to obtain other effects with an understanding of the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
