Abstract
A novel device for taking out an oil film bearing of a Morgan mill comprises a bolt, an expansion block and an expansion body, wherein one end of the expansion body is of a hollow conic structure. Four cuts are arranged on the conic structure at intervals along the longitudinal direction and enable the end where the conic structure is located to form four petal-shaped structures, and the extending part of each petal-shaped structure is provided with a pawl. The expansion block is installed in the hollow conic structure, and the bolt penetrates through the expansion block to extend into the expansion body to be in threaded connection with the inside of the expansion body. The novel device can smoothly take out the oil film bearing without influencing an eccentric sleeve, and the bearing can be taken out in one step without other steps or matching of a machine tool. Therefore, working efficiency is improved, and production cost is reduced.
Description
Technical field
The utility model relates to high-speed rod-rolling mill roller case filmatic bearing and takes out, and is specifically related to a kind of novel root filmatic bearing of press withdrawing device that rubs.
Background technology
The core component of high-speed rod-rolling mill is the roller case and the awl case, because the milling train design is compact, running speed is than higher, so filmatic bearing has been adopted in the part position in roller case and awl case.High-speed rod-rolling mill mill speed higher device operating mode is more abominable, and the replacement cycle of general filmatic bearing is probably at 6 to 8 months.The filmatic bearing of the big end of eccentric bushing is installed in the through hole when changing filmatic bearing, can adopt forcing press to extrude; But the filmatic bearing of eccentric bushing small end is installed in the blind hole, and the filmatic bearing of the lazy axle of awl case also exists same problem to never have reasonable removing method.At present on-the-spot through two kinds of methods taking-ups: 1, the most frequently used be exactly the workman by hand hacksaw bearing is cut; So it is low especially because of the little efficient in space when cutting; Hacksaw scratches the precision of eccentric bushing endoporus image workpiece through regular meeting in this way; Can not bearing is all sawed-off in order to prevent to scratch eccentric bushing, cut to a certain degree after more by hand flat chisel kick out of.2, cooperate to take out with lathe, with lathe with the filmatic bearing car thin or wash breach with milling machine after manual again flat chisel kick out of.Because the little above two kinds of methods in space cause the problem of eccentric bushing damage through regular meeting, even because major injury scrap.Cause changing that filmatic bearing efficient is low, the eccentric bushing damage is many, shortened the service life of eccentric bushing, the extra cost of equipment maintenance that increased.
Summary of the invention
A kind of novel root filmatic bearing of press withdrawing device that rubs that the purpose of the utility model provides a kind of safe and reliable, convenient disassembly, can effectively increase work efficiency, reduces production costs, security is higher.
The purpose of the utility model is achieved in that a kind of novel root filmatic bearing of press withdrawing device that rubs, and comprises bolt, expanding block and expander, and an end of expander is the pyramidal structure of hollow; This pyramidal structure longitudinally on average has 4 otch; These 4 otch make this end form four valvular structures, and the extension of each valvular structure is provided with ratchet, and expanding block is installed in the pyramidal structure of this hollow; Bolt passes expanding block and extend into expander inside, and bolt is connected with the expander internal whorl.
The utility model can take out filmatic bearing smoothly, and eccentric bushing is not impacted, and not needing other step or lathe to cooperate can disposable taking-up bearing.Both improve operating efficiency and also reduced production cost.
Description of drawings
The front view of Fig. 1 filmatic bearing withdrawing device;
The side view of Fig. 2 filmatic bearing withdrawing device;
The user mode figure of Fig. 3 filmatic bearing withdrawing device;
Wherein 1, bolt, 2, ratchet, 3, expanding block, 4, expander, 5, otch, 6, filmatic bearing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of novel root filmatic bearing of press withdrawing device that rubs comprises bolt, expanding block and expander, and an end of expander is the pyramidal structure of hollow; This pyramidal structure longitudinally on average has 4 otch; These 4 otch make this end form four valvular structures, and the extension of each valvular structure is provided with ratchet, and expanding block is installed in the pyramidal structure of this hollow; Bolt passes expanding block and extend into expander inside, and bolt is connected with the expander internal whorl.
It is fairly simple that this explanation relates to related components.The utility model takes out filmatic bearing under the situation that equipment such as not needing lathe cooperates smoothly, and Safety Design is avoided the damage to eccentric bushing.Practical implementation thes contents are as follows: the filmatic bearing withdrawing device is put into the eccentric bushing small end; Suitably device is ajusted the back swivel bolt; Bolt hauls the tapered expansion piece and in expander, moves expander is outwards expanded, and can be embedded in the bearing so the top layer material of filmatic bearing is a ratchet on the softer expanding block of terne metal.The height 1.5mm of the thickness 3mm ratchet of bearing; Calculating through the expanding block tapering can not move inward expanding on the plane that 1.5mm is pressed onto expander later on again; Guarantee that like this eccentric bushing can not receive extra expansive force, and guarantee that the degree of depth 1.5mm of expander embedding bearing can never cause damage to eccentric bushing.The postpone that puts in place of bolt pretension can or draw tool that bearing is taken out with the top tool, the disposable so smoothly taking-up work of having accomplished filmatic bearing.The utility model make the filmatic bearing dismounting and change convenient, do not need auxiliary equipment such as lathe, avoided the damage of eccentric bushing, the filmatic bearing withdrawing device has promptly improved operating efficiency, has reduced the use cost of equipment again.
