[0002] When assembling the main reducer driving bevel gear, it is necessary to select shims to ensure the bearing clearance; shim selection is generally carried out by measuring the starting torque. If the starting torque is not appropriate, the inner ring of the tapered bearing needs to be removed from the hole and installed into the hole again after adjustment; however, due to the deep hole, the inner ring of the tapered bearing cannot be removed and installed by hand without the aid of tools.

[0003] The current technical solution for assembling the inner ring of the tapered bearing is to use an adsorption tool with a strong magnet to adsorb the inner ring of the tapered bearing from the deep hole. When the inner ring of the tapered bearing is put into the deep hole again, the clearance between the inner ring of the tapered bearing and the active bevel gear is small, so a guide tool is needed to assemble it smoothly. If the adsorption tool is used to assemble the inner ring of the tapered bearing, the magnet will adsorb the inner ring, and the workpiece and the tool cannot be separated smoothly. Therefore, two sets of independent assembly tools are usually required to complete the assembly of the inner ring of the tapered bearing. However, the two sets of independent assembly tools are inconvenient to operate and are not conducive to on-site use and storage, which affects work efficiency. To this end, a person skilled in the art provides a handheld push-pull magnet separation device to solve the problems raised in the above background technology. Summary of the invention

The two states are flexible and adjustable, which can facilitate the staff to use flexibly according to the actual situation on site, adapt to the complex and changeable working environment on site, and maximize the convenience of the staff.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 10 In an embodiment of the present invention, a handheld push-pull magnet separation device includes a tooling sleeve 1 and a tooling inner core 2. The tooling sleeve 1 is installed through the tooling inner core 2, and the tooling sleeve 1 and the tooling inner core 2 are elastically slidably connected through a torsion spring 3. A retaining spring 8 for limiting the tooling sleeve 1 is provided at the bottom of the core rod of the tooling inner core 2, and a stop convex ring 10 for pressing the torsion spring 3 is provided at the upper end of the core rod of the tooling inner core 2. By utilizing the setting of the torsion spring 3, the tooling inner core 2 and the tooling sleeve 1 are maintained in an elastic compression reset state, and by providing a retaining spring 8 for limiting the tooling sleeve 1 at the bottom of the tooling inner core 2, the tooling inner core 2 is prevented from falling off the tooling sleeve 1, so that the tooling sleeve 1 and the tooling inner core 2 maintain a good elastic compression and reset state.

[0031] A plurality of groups of strong countersunk magnets 6 are arranged in a circumferential manner at the bottom of the sleeve of the tooling sleeve 1. The number of the strong countersunk magnets 6 is three groups, and the three groups of strong countersunk magnets 6 are arranged in a star-triangle symmetrical manner relative to the sleeve center of the tooling sleeve 1. By arranging the strong countersunk magnets 6 in a star-triangle symmetrical manner along the tooling sleeve 1, when the inner ring of the bearing is positioned using the bottom boss of the tooling inner core 2, the circumferentially arranged strong countersunk magnets 6 perform star-triangle fixed-point magnetic fixation on the inner ring of the bearing to ensure uniformity and firmness of the magnetic force.

[0032] The table top of each group of strong countersunk magnets 6 is screwed through with countersunk screws 61, and the strong countersunk magnets 6 and the tooling sleeve 1 are screwed and fixed by countersunk screws 61. There are two groups of countersunk screws 61 on each group of strong countersunk magnets 6, and the countersunk screws 61 are cross-slot screw structures. The countersunk screws 61 are screwed into the strong countersunk magnets 6 and the tooling sleeve 1 in an embedded form, so as to serve as a fixed connection component between the strong countersunk magnets 6 and the tooling sleeve 1. The embedded countersunk screws 61 can ensure the smoothness of the magnetic attraction surface of the strong countersunk magnet 6, and ensure the smooth magnetic attraction of the strong countersunk magnet 6 to the inner ring of the bearing.

[0033] The separation conversion mechanism includes two groups of track grooves 12 symmetrically arranged on the inner wall of the support platform 7 and a telescopic cavity 15 arranged at the bottom of the tooling inner core 2. The inside of the telescopic cavity 15 is slidably connected with a discharge push cylinder 11, and two groups of guide grooves 14 are symmetrically arranged on both sides of the chamber of the telescopic cavity 15 and cross-opposite to the track grooves 12. The top of the discharge push cylinder 11 is symmetrically provided with a guide slide 13 that passes through the guide slide 14 and the track groove 12. The track groove 12 is a spiral structure. By utilizing the double overlap of the guide slide 13 with the track groove 12 and the guide slide 14, the guide slide 13 can be used as a guide adapter of the spiral structure track groove 12. The spiral propulsion guide rail component, after the staff has magnetically probed the bearing inner ring to an appropriate depth, turns the second operating handle 5 and pushes the tooling core 2 forward, and uses the spiral guide adaptation of the guide slide buckle 13 and the track slide groove 12 to play a knob guiding role, so that the tooling core 2 can separate the bearing inner ring from the powerful countersunk magnet 6 in a knob and push manner in parallel, and complete the installation of the bearing inner ring. It is faster and more efficient for the installation of the bearing inner ring, and because the guide slide buckle 13 is under the action of downward thrust, it is always at the top of the track slide groove 12 when it is subjected to reverse force, and the unloading push cylinder 11 is limited and fixed, so that the unloading push cylinder 11 is set flush with the tooling core 2 and does not telescope or move.

[0034] The guide slide groove 14 is a horizontal structure. The intersection of the track slide groove 12 and the guide slide groove 14 overlaps with the guide slider 13. The bottom platform of the unloading push cylinder 11 and the bottom boss of the tooling inner core 2 are arranged flush with each other. By utilizing the double overlap of the guide slider 13 with the track slide groove 12 and the guide slide groove 14, the guide slider 13 can be used to adapt to the guide of the horizontal structure guide slide groove 14, and the track slide groove 12 is used as a spiral propulsion guide rail component to push the unloading push cylinder 11 out. Then, after the staff magnetically probes the inner ring of the bearing to a suitable depth, the second operating handle 5 is rotated horizontally to drive The overall structure of the tooling inner core 2 rotates. When the tooling inner core 2 rotates, it drives the guide slot 14 to rotate, so that the intersection point of the guide slot 14 and the track slot 12 changes. Since the guide slider 13 is always at the coincidence point of the track slot 12 and the guide slot 14, when the guide slider 13 is spirally displaced along the track slot 12 of the spiral structure, it is synchronously lifted and displaced along the track slot 12, pushing the unloading push cylinder 11 out of the tooling inner core 2, and pushing the bearing inner ring away from the strong countersunk magnet 6 to complete the installation of the bearing inner ring, which makes the installation of the bearing inner ring smoother and more stable.

[0035] A guide inner hole 9 is provided at the bottom of the core rod of the tooling inner core 2. By providing the guide inner hole 9 at the bottom of the tooling inner core 2, it can cooperate with the active bevel gear to play a guiding role, so that the inner ring of the bearing can be smoothly placed in the deep hole.

[0036] Two groups of first handling handles 4 are symmetrically arranged on both sides of the top sleeve of the tooling sleeve 1. The first handling handle 4 includes a first limiting seat 41 and a first support handle 43, and the first limiting seat 41 is rotatably connected to the first support handle 43 through a first rotating pin 42. The maximum rotation angle of the first handle 43 with the first rotating pin 42 as the axis is 90°. By arranging the first handling handle 4 on the tooling sleeve 1, when in use, by rotating the first support handle 43 in the first handling handle 4 upward by 90° along the first rotating pin 42 and stopping by the first limiting seat 41, the first handling handle 4 is kept in a flat state to form a T-shaped state with the tooling sleeve 1, so that the staff can use the extended first handling handle 4 to press flat on the top of the hand while handling the tooling sleeve 1 to form a stable handling and control state, and after use, by folding and storing the first handling handle 4, the occupied space is reduced, which is convenient for carrying and storage.

[0037] Two groups of second handling handles 5 are symmetrically arranged on both sides of the top rod of the tooling core 2. The second handling handle 5 includes a second limiting seat 51 and a second support handle 53, and the second limiting seat 51 is rotatably connected to the second support handle 53 through a second rotating pin 52. The maximum rotation angle of the second support handle 53 with the second rotating pin 52 as the axis is 90°. By arranging the second handling handle 5 on the tooling core 2, when in use, by rotating the second support handle 53 in the second handling handle 5 upward by 90° along the second rotating pin 52 and stopping by the second limiting seat 51, the second handling handle 5 is kept in a flat state to form a T-shaped state with the tooling core 2, so that the staff can use the extended second handling handle 5 as an extended handle while handling the tooling core 2, and the tooling core 2 can be pushed more conveniently by turning the knob. After use, by folding the first handling handle 4 and storing it, the occupied space is reduced, which is convenient for carrying and storage.

[0038] The working principle of the present invention is as follows: when the magnet separation device is used as a tool for taking out and loading the inner ring of the main bevel gear bearing of the reducer, when the inner ring of the bearing in the deep hole needs to be adsorbed, the tool sleeve 1 can be held, the separation device is brought close to the inner ring of the bearing, and the strong countersunk magnet 6 installed on the tool sleeve 1 is used to adsorb and fix the inner ring of the bearing to the separation device, so as to take out the inner ring of the bearing;

[0039] When the bearing inner ring needs to be installed later, the bearing inner ring is installed on the boss at the bottom of the tooling inner core 2 to achieve the positioning effect. At the same time, the magnetic attraction of the strong countersunk magnet 6 is used to ensure that the bearing inner ring will not fall off. At this time, the tooling sleeve 1 is held, and the first handling handle 4 is pressed flat on the hand to form a stable handling state, and the bearing inner ring is placed in the deep hole. At the same time, the guide inner hole 9 at the bottom of the tooling inner core 2 is used to cooperate with the central axis of the active bevel gear.

[0040] It plays a guiding role, allowing the inner ring of the bearing to be smoothly placed into the deep hole. After the inner ring of the bearing is installed in place, the inner ring of the bearing can be assembled in different installation methods according to the on-site installation requirements;

[0041] Furthermore, when installing the inner ring of the bearing, the guide buckle 13 and the guide adapter of the spiral structure track groove 12 can be used as a spiral propulsion guide rail component. After the staff magnetically probes the inner ring of the bearing to a suitable depth, the second operating handle 5 is turned, and the tooling inner core 2 is pushed forward for braking. The spiral guiding effect of the guide buckle 13 and the track groove 12 is used to make the tooling inner core 2 rotate and propel the inner ring of the bearing from the strong countersunk magnet 6 in a parallel manner. The dual synchronous state of rotation and propulsion makes the separation force of the inner ring of the bearing more uniform and the separation more stable. The rotation and propulsion separation is suitable for fast operation, which is faster and more efficient for the installation of the inner ring of the bearing.

[0042] Furthermore, when installing the inner ring of the bearing, the guide slide buckle 13 can be used to adapt to the guide of the horizontal structure guide slot 14, and the track slot 12 can be used as a spiral propulsion guide component to push out the unloading push cylinder 11. Then, after the staff magnetically probes the inner ring of the bearing to a suitable depth, the second handling handle 5 is horizontally rotated to drive the overall structure of the tooling inner core 2 to rotate. While the tooling inner core 2 rotates, the guide slot 14 is driven to rotate, so that the intersection point of the guide slot 14 and the track slot 12 changes. Since the guide slide buckle 13 is always at the coincidence point of the track slot 12 and the guide slot 14, and by 3 is set to be two parts, the base part is a square slider matched with the guide slide groove 14 to better play the role of lifting and lowering guidance, and the top seat part is a roller slider matched with the track slide groove 12 to better play the role of spiral guidance. Therefore, when the guide slider 13 moves along the spiral track slide groove 12, it moves up and down along the track slide groove 12 synchronously, pushes the unloading push cylinder 11 out of the tooling inner core 2, and pushes the bearing inner ring away from the strong countersunk magnet 6. In the flat push state, the thrust force on the bearing inner ring is more gentle, which is suitable for gentle operation and is more gentle and stable for the installation of the bearing inner ring;

[0043] After the assembly is completed, the separation device is taken out, and the placement and installation of the bearing inner ring can be completed according to the needs of the site. After the tooling core 2 is subsequently loosened, the elastic torsion and compression loads of the torsion spring 3 keep the combination of the tooling core 2 and the tooling sleeve 1 in the two control modes flexible and elastic reset. It replaces the traditional form of independent control of removing and inserting tooling, has the two-in-one function of removal and installation, reduces the number of tools, and its control method is flexible and changeable, and the operation is more convenient and efficient.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
