Abstract

The utility model discloses a teeth rolling mill, a feeding rod is slantingly pass through a machine platform with 45 DEG, and the two ends of the feeding rod are respectively connected with a swinging arm and a tooth rubbing assembly. A power source can drive a spindle rod to abut on a feeding cam on one end of the swinging arm through a belt pulley, a transmission rod, a big and a small gears, so the feeding cam can turn in order to drive the swinging arm to swing and make the feeding rod reciprocating move, and therefore, the tooth rubbing assembly can be driven for the tooth rubbing processing. The two side plate positions of the machine platform which is slantingly passed by the feeding rod are respectively dented with a bearing fixing section which is provided with a 45 DEG tilt surface, each bearing fixing section is respectively assembled with a fixed bearing, and the feeding rod can be sliding inserted into each bearing for sliding. Therefore, the reciprocating move of the feeding rod is smooth and stable, and the utility model can extend the service life of the swinging arm and the tooth rubbing assembly.

Description

Tooth roller

Technical field

The utility model relates to tooth roller.

Background technology

Referring to shown in Figure 1, the primary structure of existing tooth roller, group is provided with drive link 21 on board 2, utilize the belt pulley 211 of drive link 21 1 ends to connect the power source (not shown), drive drive link 21 and rotate, utilize the pinion 212 on the drive link 21 to be engaged in gear wheel 22 again, drive the rotating shaft 23 affixed with gear wheel 22, the feeding cam 231 that sets firmly together with rotating shaft 23 other ends rotates thereupon, simultaneously, by rotating shaft 23 drivening rods 24, drive the slide block 241 that joins with connecting rod 24 and up and down reciprocatingly slide; This feeding cam 231 contacts at the roller 251 of swing arm 25, make swing arm 25 along pivot 252 swings, and swing arm 25 bottoms are 45 ° of oblique feeding rods 26 that are articulated in, feeding rod 26 can be moved back and forth fast with the swing of swing arm 25, the threading group 27 that these feeding rod 26 other ends connect then can move back and forth thereupon, carries out the processing of thread.

Referring to shown in Figure 2, be the feeding rod 26 of 45 ° of oblique pivot joints, take direct oblique 45 ° mode to pass perforation 281 on board 2 side plates 28, no any with it structure of fixing in addition, so be vacant state.Therefore, when this tooth roller carried out the threading operation, feeding rod 26 easily produced the situation of rocking, and the threading operation can't be carried out smoothly; Add the action unstability of feeding rod 26, will cause the swing arm 25 that is attached thereto and the damage of threading group 27.

The utility model content

The purpose of this utility model is to provide a kind of tooth roller, and its feeding rod two ends move back and forth under two bearings, and it is smooth and easy not only to move, and more stable, can prolong swing arm and threading group service life.

The technical solution of the utility model is: a kind of tooth roller, its feeding rod is 45 ° of oblique boards that pass, two ends are connected to swing arm and threading group, by power source, through belt pulley, drive link, large and small gear, the feeding cam that drive shaft rod contacts at swing arm one end rotates, and drives the swing arm swing, make the reciprocal movement of feeding rod, drive the threading group and carry out threading processing; It is characterized in that:

Be arranged with one respectively at the oblique board biside plate place of passing of feeding rod and have 45 ° tilting bearing fixing section, be assembled with a rigid bearing respectively on each bearing fixing section, this feeding rod cunning inserts in the tooth roller of slippage in each bearing.

Advantage of the present utility model is:

1, because feeding rod two ends move back and forth under two bearings, it is smooth and easy not only to move; Simultaneously, its motion is more stable, unlikely situation about shaking.

2, because the motion quite stable of feeding rod, so, the service life of swing arm and threading group can be prolonged.

The specific embodiment

For to structure of the present utility model, technical characterictic and effect thereof, can have and further understand and be familiar with, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:

Referring to shown in Figure 3, structure of the present utility model and existing tooth roller are basic identical, feeding rod 26 is 45 ° of oblique boards 2 that pass, its two ends that protrude out connect swing arm 25 and threading group 27 respectively, by power source, through belt pulley 211, drive link 21, large and

small gear

212,22, the feeding cam 231 that drive shaft rod 23 contacts at swing arm 25 other ends rotates, drive swing arm 25 swings, make feeding rod 26 reciprocal movements, drive threading group 27 and carry out threading processing; Difference is: be the 45 ° of oblique board that passes 2 biside plates 28 places at feeding rod 26 and be arranged with one respectively and have and be 45 ° tilting bearing fixing section 29, be assembled with rigid bearing 1 respectively on each bearing fixing section 29, these feeding rod 26 sliding inserting in each bearing 1, be supported in feeding rod 26 by two bearings 1, make feeding rod 26 under two bearings 1 support, smooth and easy stable moving back and forth.

The above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; such as those who are familiar with this art; use principle of the present utility model and technical characterictic; various changes and the decoration done all should be covered by within the category that these claims protect.

Claims

1, a kind of tooth roller, the oblique board that passes of its feeding rod, two ends are connected to swing arm and threading group, by power source, through belt pulley, drive link, large and small gear, the feeding cam that drive shaft rod contacts at swing arm one end rotates, and drives the swing arm swing, make the reciprocal movement of feeding rod, drive the threading group and carry out threading processing; It is characterized in that:

Be arranged with one respectively at the oblique board biside plate place of passing of feeding rod and have tilting bearing fixing section, be assembled with a rigid bearing respectively on each bearing fixing section, this feeding rod cunning inserts in slippage in each bearing.
