Abstract

The utility model discloses a fender device for the driving rack of the pipe bender capable of regulating the working position of the driving rack. The main structure of the fender device for the driving rack of the pipe bender is a fender shaft arranged in a headstock on the external side of the driving rack; the fender shaft is contacted with the external side of the driving rack. Two regulating cavities are arranged in the headstock on the external side of the fender shaft; the two regulating cavities are respectively positioned in the position of the shaft end on both ends of the fender shaft. Each regulating cavity is respectively provided with a pair of regulating sloping blocks; wherein, one regulating sloping block is contacted with one shaft end of the fender shaft. Thread holes are respectively arranged in the headstock on the side of each regulating cavity; the thread holes are respectively provided with regulating bolts; each regulating bolt is respectively contacted with the regulating sloping block near the fender shaft. The fender device using the structure can regulate the space between the driving rack and the gear in time according to the actual conditions to guarantee the carrying out of the reliable mesh of the driving rack and the gear to guarantee the normal processing of the bending work.

Description

The retaining that drives tooth bar in the bending machine is by device
Technical field
The utility model relates to the retaining of the driving tooth bar in the bending machine by device.
Background technology
Bending machine is mainly used to tubing is bent into various required shapes.Bend pipe arm in the bending machine is one of important execution unit that carries out bending work, and the bend pipe arm is fixedlyed connected with main shaft, is installed with gear on the main shaft, and gear is meshing with each other with the driving tooth bar.When carrying out bending work, move under the driving of the drive unit of driving tooth bar in bending machine, driven gear and then rotates, and gear drives the rotation of bend pipe arm by main shaft again, with the purpose that realizes tubing is carried out bending work.Can to carry out engaged transmission reliably in order guaranteeing to drive between the rack and pinion, to be provided with gear shaft usually in the headstock that drives the tooth bar outside, gear shaft contacts with driving tooth bar, and the effect of gear shaft is that the driving tooth bar is blocked, and it can be meshed reliably with gear.But along with the increase of working time, gear shaft can wear and tear gradually, thereby can have influence on the positive engagement that drives between the rack and pinion, and then can have influence on normally carrying out of bending work.
Summary of the invention
The utility model will provide a kind of retaining that drives tooth bar in the bending machine that drives the rack and pinion positive engagement that can make by device.
For achieving the above object, the technical solution adopted in the utility model is: the retaining that drives tooth bar in the described bending machine mainly comprises by device: be arranged on the gear shaft that drives in the headstock of the tooth bar outside, gear shaft contacts with the outside that drives tooth bar; Be characterized in: in the headstock in the gear shaft outside, be provided with two and regulate the chamber, regulate the axle head position that the chamber lays respectively at the gear shaft two ends for these two; Each is regulated in the chamber and is respectively arranged with a pair of adjustment skewback, and wherein an adjustment skewback contacts with an axle head of gear shaft; Be respectively arranged with screwed hole in the headstock of each adjusting side, chamber, be respectively arranged with the adjusting bolt in the screwed hole, each is regulated bolt and contacts with the adjustment skewback of close gear shaft respectively.
The further technical scheme of the utility model is: also be provided with the wear-resisting interstage sleeve of one deck in the outside of gear shaft, wear-resisting interstage sleeve contacts with the driving tooth bar.
The utility model has the advantages that: use retaining described in the utility model by device, can in time adjust the gap that drives between the rack and pinion, guarantee to drive rack and pinion and mesh reliably, guarantee normally carrying out of bending work according to actual conditions.
Description of drawings
Fig. 1 is the structural representation of retaining described in the utility model by device;
Fig. 2 is the A-A profile that retaining leans on device among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1 and Figure 2, retaining described in the utility model mainly comprises by device: drive tooth bar 3, in the headstock that drives tooth bar 3 outsides, be provided with gear shaft 7, in the present embodiment, also be provided with the wear-resisting interstage sleeve 6 of one deck in the outside of gear shaft 7, wear-resisting interstage sleeve 6 contacts with driving tooth bar 3; The effect that wear-resisting interstage sleeve 6 is set is the wearing and tearing that reduce gear shaft 7, prolongs its service life.In the present embodiment, in the headstock 1 in gear shaft 7 outsides, be provided with two altogether and regulate chamber 8, regulate the axle head position that chamber 8 lays respectively at gear shaft 7 two ends for these two; Now regulating the chamber with one is that example illustrates its structure, in each adjusting chamber 8, be provided with a pair of adjustment skewback 9 and 10, wherein adjusting skewback 9 contacts with an axle head of gear shaft 7, in the headstock 1 of regulating 8 sides, chamber, be provided with screwed hole, be provided with in the screwed hole and regulate bolt 2, regulate bolt 2 and contact with the adjustment skewback 9 of close gear shaft 7.
The retaining of said structure by the operation principle of device is: when carrying out bending work, the same with traditional bending machine, move under the driving of the drive unit of driving tooth bar 3 in bending machine, driven gear 11 and then rotates, gear 11 drives main shaft 4 and and then rotates, main shaft 4 drives bend pipe arm 5 again and rotates, with the purpose that realizes tubing is carried out bending work.Along with the increase of working time, wear-resisting interstage sleeve 6 always wear phenomenon occurs, thereby can have influence on the positive engagement that drives between tooth bar 3 and the gear 11, and then can have influence on normally carrying out of bending work.In bending machine, be provided with retaining described in the utility model by behind the device, when wear phenomenon appears in wear-resisting interstage sleeve 6, regulate bolt 2 as long as suitably adjust, also promptly regulate the position of adjusting skewback 9, just can adjust the gap that drives between tooth bar 3 and the gear 11 easily, guarantee to drive tooth bar 3 and mesh reliably, guarantee normally carrying out of bending work with gear 11.

Claims (2)

1, the retaining that drives tooth bar in the bending machine mainly comprises by device: be arranged on the gear shaft that drives in the headstock of the tooth bar outside, gear shaft contacts with the outside that drives tooth bar; It is characterized in that: in the headstock in the gear shaft outside, be provided with two and regulate the chamber, regulate the axle head position that the chamber lays respectively at the gear shaft two ends for these two; Each is regulated in the chamber and is respectively arranged with a pair of adjustment skewback, and wherein an adjustment skewback contacts with an axle head of gear shaft; Be respectively arranged with screwed hole in the headstock of each adjusting side, chamber, be respectively arranged with the adjusting bolt in the screwed hole, each is regulated bolt and contacts with the adjustment skewback of close gear shaft respectively.
2, retaining as claimed in claim 1 is characterized in that by device: also be provided with the wear-resisting interstage sleeve of one deck in the outside of gear shaft, wear-resisting interstage sleeve contacts with the driving tooth bar.
