Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-3, the thrust bearing heat treatment production line comprises a roller type conveying device 1, a heating furnace 2, a quenching tank 3 and a tempering furnace 4, wherein the heating furnace 2, the quenching tank 3 and the tempering furnace 4 are sequentially arranged on the roller type conveying device 1. Roller conveyor 1's afterbody fixed mounting has horizontal plate 5, the afterbody fixed mounting of horizontal plate 5 has stripper 6, the top of horizontal plate 5 and stripper 6 is fixed mounting respectively has two first curb plates 7 and two second curb plates 8, equal fixed mounting has limiting plate 9 on the face in opposite directions of two first curb plates 7, wherein, two limiting plates 9 all are the slope setting, it is further, the bottom fixed mounting of stripper 6 has the supporting leg, it is concrete, bearing housing heat treatment process is prior art, do not do at this and describe repeatedly more, through setting up many supporting legs, be used for supporting stripper 6. Spacing spout 10 has been seted up at the top of stripper 6, rotates on the both ends inner wall of spacing spout 10 to be connected with many dwang 11, and two second curb plates 8 are equallyd divide on the face in opposite directions and do not fixed mounting have a plurality of coupling mechanisms, are equipped with buffer board 12 on the coupling mechanism, are provided with buffer gear on the lateral wall of buffer board 12. Coupling mechanism includes fixed plate 13 and first reset spring 14 of fixed mounting on the 8 lateral walls of second curb plate, fixedly connected with dead lever 15 between the top of fixed plate 13 and stripper 6, and on dead lever 15 was located to the one end rotation cover of buffer board 12, the lateral wall fixed connection of the one end of first reset spring 14 and buffer board 12, and further, the through hole has been seted up on the lateral wall of buffer board 12, and the through hole rotates the cover and locates on dead lever 15. The buffer plate 12 is in an inclined arrangement in an initial state, the through hole is formed in the side wall of one end of the buffer plate 12, the through hole in the buffer plate 12 is sleeved on the fixing rod 15, the purpose that the buffer plate 12 is rotatably connected with the second side plate 8 is achieved, and therefore the purpose of buffering the bearing sleeve is achieved through the first reset spring 14. Buffer gear is including offering the recess 16 on buffer board 12 lateral wall, and it has buffer block 17 to slide in the recess 16, and a plurality of second buffer spring 18 of fixed connection between the bottom of buffer block 17 and recess 16.

When the bearing sleeve strikes the buffer plate 12, the bearing firstly strikes the buffer block 17, so that before the buffer plate 12 rotates, the buffer block 17 slides in the groove 16, and the purpose of relieving the impact force of the bearing sleeve is realized by extruding the second return spring 18.

According to the invention, after being sequentially conveyed into a heating furnace 2, a quenching tank 3 and a tempering furnace 4 through a roller type conveying device 1, a bearing sleeve achieves the purpose of heat treatment, then is conveyed onto a horizontal plate 5 through the roller type conveying device 1, slides on the horizontal plate 5 under the pushing of the roller type conveying device 1, is corrected to the central line position of the horizontal plate 5 through arranging two limiting plates 9, and slides into a limiting sliding groove 10 on a discharging plate 6 under the inertia effect of the bearing sleeve.

Because stripper 6 is the slope setting, the bearing housing slides downwards in spacing spout 10 through its self gravity, through set up dwang 11 in spacing spout 10 for when the bearing housing slided on many dwang 11, dwang 11 also can rotate, realizes reducing the purpose of bearing housing wearing and tearing.

Bearing housing is at the in-process of gliding down on dwang 11, the bearing housing can strike polylith buffer board 12 in proper order, thereby make buffer board 12 rotate, through the tensile first reset spring 14 of buffer board 12, realize the purpose to the bearing housing buffering, prevent that the bearing housing gliding velocity is too fast, and when the bearing housing strikes buffer board 12, the bearing housing strikes buffer block 17 on buffer board 12 at first, buffer block 17 then is to recess 16 internal motion, through extrusion second reset spring 18, the purpose of the impact of bearing housing is alleviated in the realization, avoid the bearing housing damage, when buffer board 12 rotates to not contacting with the bearing housing, reset through first reset spring 14, through second reset spring 18, realize the reseing of buffer block 17.
