Abstract
The utility model relates to a bearing housing extracting device belonging to the technical field of hand-operated tools and aiming at solving the problem of hard disassembly of the bearing housing. The bearing housing extracting device structurally comprises a cross beam, a holding paw and a pressurizing rod. After the improvement, the lower end of the pressure rod is provided with a pressurizing head and an extracting paw; the pressurizing head is a flat cone, is arranged in the extracting paw and is fixedly connected with the lower end of the pressurizing rod; the extracting paw is in a double-section split involutory structure and is provided with a ring groove in the upper part; a coupling ring is arranged in the ring groove; the middle section of the inner wall of the extracting paw is provided with a conical surface matched with the cone angle of the pressurizing head; and the lower end of the extracting paw is provided with an extracting inclined surface. The utility model adopts the design of spiral pressurization and force increase on the inclined extracting inclined surface of the extracting paw, improves the force bearing state of the weak extracting paw, and can effectively solve the problem of machine part damage resulted from the disassembly of the bearing of some equipment, reduce the maintenance difficulty, shorten the maintenance time of the equipment and improve the operation rate of the equipment.
Description
Technical field
The utility model relates to a kind of specific purpose tool, and the bearing outside dismounting driver-extractor especially for interior overcoat separable bearing belongs to the hand-operated tools technical field.
Background technology
Between the interior cover of bearing and the axle, the interference fit that adopt are connected more between overcoat and the bearing block, need be when the dismounting bearing by specific purpose tool, in order to avoid in unloading process, damage the parts of being correlated with.The bearing such as the circular cone roller bearing that can separate for inside and outside cover, cover is dismantled after can together taking off with axle again in when dismounting, and bearing outside is unloaded next difficulty relatively from bearing block, particularly assembling the big and narrow and small occasion of the device space of the magnitude of interference, the bearing outside dismounting is more difficult.As a kind of rapier loom head; adopt universal joint to add the transmission mechanism of connecting rod in its transmission case; the circular motion of main shaft is become the swing of connecting rod; the space is little in the transmission case; moving component speed height, frictional force are big; the used circular cone roller bearing assembling magnitude of interference is big, assembly precision requires high; thereby make the dismounting maintenance difficult; can't cause some associated components to damage and damage through regular meeting in the bearing outside dismounting with avoiding; not only increased maintenance time; influence the operational efficiency of equipment, and strengthened maintenance cost, increased production cost.In addition, common driver-extractor is so that fixed claw produces pulling force by the rotation pressure rod, thereby part is removed, but it is very big and when having corrosion to exist at the assembling magnitude of interference, can produce very big pulling force to the claw of fixed claw, claw intensity is then essential to increase the claw size in order to improve, thereby has further limited the usage space occasion of instrument.
Summary of the invention
The utility model be used to overcome the defective of prior art and provide a kind of stressed rationally, convenient disassembly, quick and can avoid damaging the bearing outside driver-extractor of relevant parts.
The alleged problem of the utility model solves with following technical proposals:
A kind of bearing outside driver-extractor, comprise crossbeam, fixed claw and pressure rod in the formation, described fixed claw is hinged on the crossbeam two ends, pressure rod cooperates with the crossbeam spiral, the pressure rod upper end is provided with turning handle, its special feature is: described pressure rod bottom is provided with polishing head and plays pusher dog, described polishing head is flat cone, it has been positioned at pusher dog, has been fixed in the pressure rod lower end, playing pusher dog is the involutory structures of two lobe splits, and its top is provided with annular groove, is provided with draw-barring in the annular groove, play pusher dog inwall stage casing and be provided with the conical surface that mates with the polishing head cone angle, a pusher dog lower end has been provided with pulls out the inclined-plane.
Above-mentioned bearing outside driver-extractor, described polishing head cone angle is 25～45 °, described oblique angle β that pulls out the inclined-plane is 25～30 °.
Above-mentioned bearing outside driver-extractor, described pusher dog upper end is provided with over cap.
The utility model improves at problems such as small space bearing outside dismounting difficulty and common driver-extractor claw stresses, described driver-extractor adopts screw press, plays the reinforcement design of pusher dog inclined-plane, this design has improved the stress of driver-extractor weak link claw, help making full use of characteristic of material mechanics, dwindle the claw size, enlarge the scope of application of instrument, and prolonged the life-span of instrument.Adopt the utility model, can effectively solve the problem of the removing damaged parts of some equipment bearing overcoat, reduce maintenance of equipment difficulty, maintenance cost and maintenance time, reduce maintenance personal's labour intensity, improve equipment operation rate.

Label is expressed as follows in the accompanying drawing: 1. fixed claw; 2. crossbeam; 3. turning handle, 4. over cap, 5. pressure rod; 6. coupling ring; 7. polishing head; 8. play pusher dog; 8-1. are pulled out the inclined-plane; 8-2. conical surfaces; 9. annular groove; 10. split inloading part.
The specific embodiment
Referring to Fig. 1, the utility model comprises crossbeam 2, fixed claw 1 and pressure rod 7 in constituting, and fixed claw is hinged on the crossbeam two ends, and pressure rod cooperates with the crossbeam spiral, and the pressure rod upper end is provided with turning handle 3.
Different with common driver-extractor, the utility model is mainly used in the dismounting of small space bearing outside.Referring to Fig. 1～5, pressure rod 5 bottoms are provided with polishing head 7 and play pusher dog 8, polishing head is flat cone, it has been positioned at pusher dog, has been fixed in the pressure rod lower end, playing pusher dog is the involutory structures of two lobe splits, its top is provided with annular groove 9, be provided with draw-barring 6 in the annular groove, two parts hoop that draw-barring will play pusher dog is an one, play pusher dog inwall stage casing and be provided with the conical surface 8-2 that mates with the polishing head cone angle, polishing head promptly presses on this conical surface, is polishing head conical surface angle [alpha]?, this angle also has been the angle of the pusher dog conical surface.Play the pusher dog lower end and be provided with and pull out inclined-plane 8-1, the oblique angle β that pulls out the inclined-plane is 25～30 °.
During use, put into the hole that is disassembled part playing pusher dog, fixed claw hooks the appropriate location of machine part so that driver-extractor is able to good fixing and be unlikely to slippage, the rotation turning handle, making pressure rod promote polishing head moves downward, thereby the pusher dog bottom is opened, pulled out the inclined-plane by rising of a pusher dog and upwards promote split inloading part 10, split inloading part is removed.
