Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a lathe which is convenient for machining bearing outer sleeves. Background Art

[0002] Bearings are an important component in mechanical equipment. They are mainly used to support mechanical rotating bodies and reduce the friction coefficient during their movement. Bearing rings are an important component in bearings. Bearing rings need to be processed using a processing lathe during the production process.

[0003] The current processing lathes are limited by the inherent structure of the clamping mechanism and often find it difficult to position the bearing rings well, which leads to the phenomenon that the bearing rings are easily offset during the processing, making the bearing rings easily damaged during processing, thereby reducing the applicability of the processing lathes. Secondly, the existing lathes have the phenomenon of metal debris flying during the bearing ring processing stage. Some metal debris are prone to rebound after contacting the inner wall of the lathe. On the one hand, the randomly flying metal debris will cause sanitary dead corners inside the lathe that are difficult to clean. On the other hand, the rebounding metal debris will break away from the lathe and cause injuries to the staff, greatly reducing safety.

[0004] To this end, a lathe that is convenient for processing bearing sleeves is proposed, which has the advantages of easy and reliable clamping of bearing rings and preventing debris from splashing, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a lathe for conveniently processing a bearing outer sleeve.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lathe for convenient bearing sleeve processing, comprising a lathe body, a main spindle box is arranged at the left end of the lathe body, and a chuck is arranged on the side wall of the main spindle box, a tailstock is arranged at the end of the lathe body away from the chuck, and a threaded column is fixedly connected to a side of the tailstock facing the chuck, an auxiliary chuck is sleeved and installed on the threaded column, and two rectangular openings are opened on the surface of the auxiliary chuck, and a clamping claw is inserted in each rectangular opening of the auxiliary chuck, two cylinders are fixedly connected to the clamping claws in the two rectangular openings respectively, a slide box is arranged between the chuck and the tailstock, and a screw rod is connected to the inner side surface of the slide box through a screw rod sleeve, and the screw rod of the slide box is connected to the motor built into the spindle box through a coupling, a tool holder is fixedly installed on the top of the slide box, an adsorption steel plate is fixedly installed on the inner wall surface of the lathe body shell, and a plurality of electromagnets are fixed on the back of the adsorption steel plate.

[0007] As a further description of the above technical solution: a collecting box is welded to the bottom of the adsorption steel plate, and an opening is formed on the top surface of the collecting box.

[0008] As a further description of the above technical solution: a plurality of mounting seats are welded to one side of the adsorption steel plate with the electromagnet, and each mounting seat is provided with a rubber gasket, and the rubber gasket of the mounting seat is provided with bolts connected to the inner wall of the lathe body.

[0009] As a further description of the above technical solution: rectangular guide blocks are welded on both sides of the clamping jaw, and two strip-shaped guide grooves are provided on the inner side surface of the rectangular opening corresponding to the guide blocks.

[0010] As a further description of the above technical solution: a mounting hole is opened at the center of the auxiliary chuck corresponding to the threaded column, a nut is screwed on the part of the threaded column passing through the mounting hole, and the end face of the nut abuts against the auxiliary chuck.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, a chuck and a tailstock with an auxiliary chuck are arranged inside a lathe body. By bringing the tailstock of the lathe body close to the right end of the bearing ring to be processed, the auxiliary chuck is brought into contact with the right end face of the bearing ring to be processed, and the two clamping claws on the surface of the auxiliary chuck are respectively extended to the inner ring of the bearing ring to be processed, and then the cylinder is started to extend, so that the cylinder drives the clamping claw to move in the rectangular opening, and then the guide blocks on both sides of the clamping claw slide with the guide grooves provided on the inner side of the rectangular opening, so that the clamping claw can be stably pressed against the inner wall of the bearing ring. In this process, a plurality of clamping claws provided on the end face of the chuck are used as the main clamping mechanism of the bearing ring, so as to achieve the purpose of locking the bearing ring. Compared with the prior art, the purpose of firmly clamping the bearing ring is achieved by combining the chuck and the detachable auxiliary chuck on the tailstock, thereby avoiding the phenomenon of displacement or damage of the bearing ring during the processing stage.

[0015] In the utility model, an adsorption steel plate with an electromagnet and a collection box is arranged on the inner wall surface of the lathe body.

On the one hand, it is prevented that the metal debris is randomly splashed to cause a sanitary dead corner inside the lathe that is difficult to clean. On the other hand, it is prevented that the rebounded metal debris escapes from the lathe and causes injuries to the staff. By cutting off the power supply of the electromagnet, the metal debris on the surface of the adsorption steel plate is forced to fall into the collection box, which is easy to clean and has high safety.

Among them, the magnetic force range formed by the opening state of the plurality of electromagnets 17 can fully cover the adsorption steel plate 9, so as to adsorb and collect the splashing debris;

[0024] In one embodiment, a collecting box 15 is welded to the bottom of the adsorption steel plate 9, and an opening is provided on the top surface of the collecting box 15. By setting the opening and the collecting box 15 and cutting off the power supply of the electromagnet 17, metal debris on the surface of the adsorption steel plate 9 is forced to fall into the collecting box 15, thereby facilitating the collection of some splashed metal debris and facilitating cleaning.

[0030] Working principle:

[0031] When in use, firstly, the left end of the bearing ring is clamped by using the several claws provided on the end face of the chuck 3 as the main clamping mechanism of the bearing ring, and then the tailstock 6 of the lathe body 1 is brought close to the right end of the bearing ring to be processed, so that the auxiliary chuck 8 is brought into contact with the right end face of the bearing ring to be processed, and the two claws 11 on the surface of the auxiliary chuck 8 are respectively extended to the inner ring of the bearing ring to be processed, and then the cylinder 14 is started to extend, so that the cylinder 14 drives the claw 11 to move in the rectangular opening 10, and then the guide blocks 12 on both sides of the claw 11 slide with the guide grooves 13 provided on the inner side of the rectangular opening 10, so that the claw 11 can be stably pressed against the inner wall of the bearing ring, so as to achieve The locking of the bearing ring makes it convenient for the tool holder 5 of the lathe body 1 to perform turning processing on the bearing ring. When processing flying metal debris, by starting a number of electromagnets 17 installed on the back of the adsorption steel plate 9, the adsorption steel plate 9 itself is made magnetic. When the flying metal debris contacts the adsorption steel plate 9, the metal debris is adsorbed on the surface of the adsorption steel plate 9. On the one hand, it prevents the metal debris from flying arbitrarily and causing sanitary dead corners that are difficult to clean inside the lathe. On the other hand, it prevents the rebounding metal debris from escaping from the lathe and causing injuries to the staff. When the bearing ring processing is completed, by cutting off the power supply of the electromagnet 17, the metal debris on the surface of the adsorption steel plate 9 is forced to fall into the collection box 15.
