Technical Field

The invention belongs to the technical field of machining, and particularly relates to a clamp for machining an inner hole of a gear shaft.

Background

In the field of machining, people need to frequently carry out external machining (such as hobbing and chamfering) on the surfaces of shaft parts so as to meet the use requirements of the parts, such as machining inner holes of gear shafts.

If the application number is: CN201721723692.8 discloses a gear shaft processing clamp, which realizes the fastening and loosening of a key seat by a matching seat, a spinning piece and a pressing plate, and the tightening mechanism has flexible design and convenient operation; the structure is stable, the limiting is firm in the transverse direction and the longitudinal direction, the workpiece can be prevented from being excessively clamped, and the service life of the clamp is ensured; the precision of gear shaft processing or detection is guaranteed, the processing and production requirements of enterprises are met, the application range is wide, and the clamp is suitable for a gear shaft processing clamp.

Based on the aforesaid, traditional anchor clamps expose in the outside in the surface of processing the gear shaft, iron fillings or other article that splash when processing cause the injury to the surface of gear shaft easily, secondly need aim at the exit tube of cutting fluid processing position, and the skew takes place easily at the exit tube in the course of working, leads to the cooling failure.

Disclosure of Invention

In order to solve the technical problems, the invention provides a gear shaft inner hole machining clamp, which aims to solve the problems that the outer surface of a gear shaft is exposed outside, the outer surface of the gear shaft is easily damaged during machining, and a cutting fluid outlet pipe is easily deviated during machining, so that the cooling is failed.

The invention relates to a clamp for processing an inner hole of a gear shaft, which is achieved by the following specific technical means:

a gear shaft inner hole machining clamp comprises a lower supporting plate and an upper pressing plate; the lower supporting plate and the upper pressing plate are sequentially arranged on the upper side of the base and are slidably mounted on the guide screw rod, the upper end and the lower end of the gear shaft are respectively inserted into the upper through hole of the upper pressing plate and the lower through hole of the lower supporting plate, the clamping nut is screwed on the guide screw rod for fixation, the bottom end of the guide screw rod is connected onto the base, and the outer end side of the upper through hole is further provided with a spray cylinder.

Furthermore, a collecting cylinder is arranged on the base and is arranged right below the lower through hole.

Furthermore, the bottom side of the lower supporting plate is provided with a limiting cylinder in a sliding mode through an adjusting screw rod, the limiting cylinder is fixed on the adjusting screw rod through an adjusting nut, and the inner wall of the limiting cylinder is provided with a key groove.

Further, the inboard seal installation of a section of thick bamboo sprays has two sets of baffles to separate into three groups through the baffle and spray the chamber, and spray the rear end in chamber and still be connected with respectively on the liquid inlet is managed and is connected to a set of house steward respectively.

Furthermore, three rows of annular spraying nozzles are embedded in the inner side of the spraying cylinder, and the three groups of spraying nozzles are respectively communicated with the three groups of spraying cavities.

The invention at least comprises the following beneficial effects:

according to the invention, the upper pressing plate is arranged and the limiting cylinder is connected to the bottom of the lower supporting plate, when the upper end and the lower end of the gear shaft are inserted into the through hole, the gear shaft is pressed and fixed by the upper pressing plate, the lower end of the gear shaft is inserted into the limiting cylinder, and the key on the gear shaft can be clamped with the key groove on the inner wall of the limiting cylinder to clamp the bottom of the gear shaft, so that the gear shaft is prevented from falling off from the gear, the outer surface of the gear shaft can be covered by the upper pressing plate, and the outer surface of the gear shaft is prevented from being damaged in the machining process.

According to the invention, the spray cylinder is arranged on the upper pressing plate, when the gear shaft is processed, the upper cutting fluid pipe can be connected to the main fluid inlet pipe, so that the cutting fluid enters the three groups of spray cavities and is sprayed out through the nozzles, the contact area between the cutting fluid and the gear shaft can be increased, the deviation of the cutting fluid outlet pipe is effectively avoided, and the cooling effect during the gear shaft processing is further improved.
