Abstract

The utility model discloses a positioning device which comprises a lathe bed. Position guiding pipes are arranged at an inlet and an outlet of the lathe bed, the positioning device further comprises a fixing support and a connection rod which are both arranged on the peripheries of the positioning guiding pipes, the fixing support is connected with the connection rod, one end of the connection rod is provided with a spring, and the other end of the connection rod is fixedly provided with a rolling roller. The spring and a rolling shaft are arranged, the lever principle is used for exerting axial pressure on a line rod, meanwhile, the line rod is evenly stressed, so that the line rod is located at the center where a turning tool rotates around all the time when the line rod enters and gets out of a lathe, and the purposes of stably positioning the line rod and improving machining precision are achieved.

Description

A kind of positioner

Technical field

The utility model relates to metalworking technology field, is specifically related to a kind of for the fixture in lathe process to wire shaft.

Background technology

When adopting Centreless lathe to remove the defects such as the oxide skin on wire shaft surface or segregation knurl, conventionally Centreless lathe is toward the direction, helical form car is except the lip-deep defect of line bar, the rotation meeting of its lathe tool produces a torsion to line bar, therefore must there is a chucking power guarantee rotation lathe tool normal operation that is greater than torsion, otherwise very easily cause line bar to occur rotation, therefore realize line bar maintenance center in processed engineering and stablize, the crudy of line bar is had to larger impact.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of positioner, by spring and the axis of rolling are set, utilize bar thick stick principle to give line bar axial compressive force, make stress equalization simultaneously, make line bar when turnover lathe, all the time the center around rotation in lathe tool, to reach the stable position to line bar, promote the object of machining accuracy.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of positioner, comprise lathe bed, entrance position at described lathe bed is provided with and leads position pipe with outlet position, also comprise that described in being arranged at, leading position manages peripheral fixed mount and connecting rod, described fixed mount is connected with described connecting rod, one end of described connecting rod is provided with spring, and the other end is fixed with rolling roller.

Preferably, described spring is uniformly distributed in the described pipe periphery, position of leading.

Further, described spring is high resiliency spring.

Beneficial effect, the utility model, by utilizing bar thick stick principle, at the two ends of connecting rod difference mounting spring and rolling roller, can make line bar remain on same center line when turnover lathe, has realized stable position, has promoted the precision of processing.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the front view schematic diagram of the disclosed a kind of positioner of the utility model embodiment.

Numeral and the represented corresponding component title of letter in figure:

1. lead position pipe; 2. spring; 3. lathe bed; 4. line bar; 5. fixed mount; 6. rolling roller; 7. connecting rod.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment

As shown in Figure 1, a kind of positioner, comprise lathe bed 3, entrance position at described lathe bed is provided with and leads position pipe 1 with outlet position, also comprise fixed mount 5 and the connecting rod 7 of described in being arranged at, leading pipe 1 periphery, position, described fixed mount 5 is connected with described connecting rod 7, and one end of described connecting rod 7 is provided with high resiliency spring 2, described spring 2 is uniformly distributed in described pipe 1 periphery, position of leading, and the other end is fixed with rolling roller 6.Line bar 4 is transferred to the entrance position of described lathe bed 3, line bar 4 is managed 1 o'clock through leading position, because the one end at described connecting rod 7 is provided with high resiliency spring 2, therefore described rolling roller can be exerted pressure to the axial plane of line bar 4, and the effect that the pressure of line bar 4 axial plane different directions can be exerted all one's strength is cancelled each other, but can make line bar 4 remain on same center line, like this when lathe tool is in the process at rotating vehicle place, can not make line bar 4 produce skew, promote the precision of processing.

Above-described is only the preferred embodiment of a kind of positioner of the utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.

Claims

1. a positioner, comprise lathe bed, entrance position at described lathe bed is provided with and leads position pipe with outlet position, it is characterized in that, also comprise that described in being arranged at, leading position manages peripheral fixed mount and connecting rod, described fixed mount is connected with described connecting rod, and one end of described connecting rod is provided with spring, and the other end is fixed with rolling roller.

2. a kind of positioner according to claim 1, is characterized in that, described spring is uniformly distributed in the described pipe periphery, position of leading.

3. a kind of positioner according to claim 2, is characterized in that, described spring is high resiliency spring.
