Description
Technical Field
[0001] This application belongs to the technical field of roll disassembly equipment, specifically relating to a roll separation tooling. Background Technology
[0002] Separating the roll from the bearing housing is a necessary operation when overhauling or replacing a worn-out roll. During field operations, rust easily forms between the bearing housing locking ring and the roll bearing seat, making separation difficult. Many field operations use methods such as tapping or applying rust remover to assist in separating the bearing housing from the roll, but these methods can damage both the roll and the bearing housing. Summary of the Invention
[0003] To address the technical problem that the current process of separating the bearing housing from the roll can damage both the roll and the bearing housing, this application provides a roll separation tooling.
[0004] In a first aspect of this application, a roll separation tooling is provided, comprising:
[0005] The base body has a first through hole in the middle;
[0006] A separating component is slidably fitted with the first through hole. One end of the separating component is provided with a stud, and the other end of the separating component is provided with a limiting part that can abut against the base body.
[0007] Connectors, at least two of the connectors are disposed on the periphery of the base;
[0008] After the connecting member is threadedly connected to the first internal threaded hole on the bearing seat, there is a gap between the seat body and the end face of the roll. The stud of the separating member can be threadedly connected to the second internal threaded hole on the end face of the roll, and the limiting part can abut against the seat body.
[0009] In some embodiments, the first through hole is provided with an internal thread that mates with the stud thread.
[0010] In some embodiments, the base is provided with at least two observation holes, which are arranged around the first through hole.
[0011] In some embodiments, the seat has a recess in the middle, and the first through hole is provided in the recess in the middle of the seat, so that after the connector is threadedly connected to the first internal thread hole on the bearing seat, there is a gap between the seat and the end face of the roll.
[0012] In some embodiments, the base includes a second nut and two opposing support rods, the second nut being fixedly disposed between the two support rods; the connector is disposed between the two support rods, and the two connectors are respectively located on both sides of the second nut.
[0013] In some embodiments, the connector includes a first nut and a first screw threadedly connected to the first nut, the threads of the first screw engaging with the threads of the first internal threaded hole.
[0014] In some embodiments, a limiting sleeve is fitted onto the end of the first screw away from the nut, the length of which is less than the difference between the length of the first screw and the thickness of the first nut.
[0015] In some embodiments, the end face of the limiting part is provided with an internal hexagonal hole.
[0016] In some embodiments, the roll separating fixture further includes a drive member operably connected to the separating member to drive the stud of the separating member to thread it into the second internal threaded hole.
[0017] In some embodiments, the drive element includes a drive arm, a handle, and a connecting arm connecting the drive arm and the handle, wherein an end of the drive arm is operably connected to an end of the separator.
[0018] According to one or more embodiments of this application, the roll separation fixture is connected by a stud and a second internal threaded hole, so that the connecting part is restricted by the limiting part. Compared with the seat body, which can only rotate and cannot move radially towards the roll, the threaded engagement of the stud and the second internal threaded hole can drive the roll to move towards the seat body. The roll can be made to protrude from the bearing seat without hitting the roll or bearing seat. The roll can then be pulled out using other equipment. The process of separating the roll and bearing seat causes less damage to the roll and bearing seat, which can improve the service life of the roll and bearing seat. Attached Figure Description

[0025] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0026] This application is described below with reference to the accompanying drawings and specific embodiments:
[0027] Please see Figure 1-4 According to a first aspect of this application, a roll separation fixture is provided, comprising a base 300, a separator 400, and at least two connecting members 500. The base 300 has a first through hole in the middle. The separator 400 is slidably fitted with the first through hole. One end of the separator 400 is provided with a stud 410, and the other end of the separator 400 is provided with a limiting part 420 that can abut against the base 300. At least two connecting members 500 are disposed on the periphery of the base 300. After the connecting member 500 is threadedly connected to the first internal threaded hole on the bearing seat 200, there is a gap between the end face of the base 300 and the roll 100. The stud 410 of the separator 400 can be threadedly connected to the second internal threaded hole on the end face of the roll 100, and the limiting part 420 can abut against the base 300.
[0028] Understandably, after the connector 500 installs the seat 300 onto the bearing housing 200, the bearing housing 200 and the seat 300 remain relatively stationary. The separator 400 passes through the first through hole and connects to the second internal threaded hole on the end face of the roll 100. Driving the separator 400 forward causes the limiting portion 420 at the other end of the connector 500 to gradually approach the seat 300 and eventually abut against the surface of the seat 300. Continuing to drive the separator 400 forward, the stud 410 and the second internal threaded hole remain threadedly connected, while the connector 500 is restrained by the limiting portion 420. Compared to the seat 300, which can only rotate but cannot move radially closer to the roll 100, the threaded engagement of the stud 410 with the second internal threaded hole allows the roll 100 to move closer to the seat 300. This eliminates the need to strike the roll 100 or the bearing seat 200 to make the roll 100 protrude from the bearing seat 200. The roll 100 can then be pulled out using other equipment. The process of separating the roll 100 and the bearing seat 200 causes less damage to them and can improve their service life.
[0029] In some embodiments, the first internal threaded hole can be an existing threaded hole in the bearing housing 200, and the second internal threaded hole can be an existing threaded hole on the end face of the roll 100. Of course, if the existing end faces of the bearing housing 200 and the roll 100 do not have threaded holes, threaded holes that match the connecting member 500 and the separating member 400 can be provided. The axis of the second internal threaded hole is coaxial with the axis of the roll 100. After the connecting member 500 is threadedly connected to the first internal threaded hole on the bearing housing 200, the axis of the second internal threaded hole is coaxial with the axis of the first through hole.
[0030] In some embodiments, the first through hole is provided with an internal thread that engages with the stud 410. When multiple connectors 500 are connected to the bearing housing 200, the axis of the second internally threaded hole is coaxial with the axis of the first through hole. After the stud 410 of the separating member 400 is threaded into the internal thread of the first through hole, alignment can be quickly achieved, shortening the time required for the stud 410 to be threaded into the second internally threaded hole, thereby improving the efficiency of separating the roll 100 and the bearing housing 200.
[0031] In some embodiments, the housing 300 is provided with at least two observation holes 310, which are arranged around the first through hole. The observation holes 310 facilitate the operator to align the stud 410 with the second internal threaded hole, shortening the screwing time between the stud 410 and the second internal threaded hole, thereby improving the efficiency of separating the roll 100 and the bearing housing 200.
[0032] In some embodiments, the seat 300 has a recess in the middle, and a first through hole is provided in the recess in the middle of the seat 300, so that after the connector 500 is threadedly connected to the first internal threaded hole on the bearing seat 200, there is a gap between the end faces of the seat 300 and the roll 100, so as to allow for a position where the roll 100 protrudes relative to the bearing seat 200. Of course, the gap between the end faces of the seat 300 and the roll 100 can also be achieved by the operator controlling the threaded position of the connector 500 and the first internal threaded hole.
[0033] In some embodiments, the base 300 includes a second nut and two opposing support rods 320, with the second nut fixedly disposed between the two support rods 320. Connecting members 500 are disposed between the two support rods 320, with the two connecting members 500 located on opposite sides of the second nut. The second nut has an internal thread that mates with the stud 410 of the separating member 400. After the stud 410 is threadedly connected to the second nut, it can be quickly aligned, shortening the time required for the stud 410 to be threaded into the second internal thread hole, thereby improving the efficiency of the separating roller 100 and the bearing seat 200. Furthermore, the entire base 300 has a simple structure and is easy to manufacture.
[0034] In some embodiments, the connector 500 includes a first nut and a first screw threadedly connected to the first nut, the thread of the first screw engaging with the thread of a first internal threaded hole. In this case, the structure of the connector 500 is relatively simple, and the first nut can be welded to the base 300.
[0035] In some embodiments, a limiting sleeve is fitted onto the end of the first screw away from the nut. The length of the limiting sleeve is less than the difference between the length of the first screw and the thickness of the first nut. That is, the limiting sleeve limits the gap between the seat 300 and the end face of the roll 100, which helps to improve the alignment accuracy between the axis of the first through hole and the axis of the second internal threaded hole, and improves the stability of the seat 300.
[0036] In some embodiments, the end face of the limiting part 420 is provided with an internal hexagonal hole 421, which means that the separation part 400 can be driven to rotate using a hexagonal wrench, without the need to provide an additional driving part, which is readily available and can reduce development costs.
[0037] Of course, in some embodiments, the roll separating fixture also includes a drive component, which is operatively connected to the separating member 400 to drive the stud 410 of the separating member 400 to be threadedly connected to the second internal threaded hole. The separating member 400 is driven by providing the drive component. The drive component can be a motor, and the output shaft of the motor is connected to the limiting part 420 through a coupling to drive the separating member 400 to rotate.
[0038] In some embodiments, the drive element includes a drive arm, a handle, and a connecting arm connecting the drive arm and the handle, with the end of the drive arm operably connected to the end of the separator 400. By extending the lever arm of the drive arm, the operator can drive the separator 400 to rotate in both directions with a smaller force, which can improve the efficiency of the operator in separating the roll 100 and the bearing housing 200, and of course, reduce the damage to the roll 100 and the bearing housing 200.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
