Description

Gear chamfering iron chip protection device

Technical Field

The utility model belongs to the technical field of gear machining, specifically relate to a gear chamfer iron fillings protector.

Background

At present, a chamfering process after gear hobbing is integrated on a hobbing machine, namely, one main shaft of a double main shaft on the hobbing machine controls hobbing, and the other main shaft controls chamfering. Specifically, a manipulator on the gear hobbing machine grabs a workpiece in a feeding area for gear hobbing, then takes out the workpiece which completes the gear hobbing process and feeds a new workpiece for gear hobbing, and the part which completes the gear hobbing process is switched to a chamfering process for chamfering. A large amount of iron filings are splashed in the chamfering process, the production environment is seriously affected by the splashed iron filings, and particularly when the iron filings are splashed on a mechanical hand switch, the mechanical hand can generate wrong actions, so that the risk of damaging a machine tool is caused.

In order to prevent iron filings from splashing and not to interfere the action of a manipulator, the specification of the Chinese utility model patent CN201420834844.1 discloses a protective device of a built-in chamfering and deburring mechanism of a gear hobbing machine, the protective device comprises a fixed protective cover fixedly arranged on a sliding plate of the dry cutting hobbing machine and a movable door arranged on the fixed protective cover in a sliding fit manner, wherein the fixed protective cover is provided with a abdicating hole for the internal chamfering and deburring mechanism to pass through, and an opening and closing mechanism for driving the movable door to open or close the abdicating hole in a sliding way is also arranged in the fixed protective cover, the opening and closing mechanism comprises a cylinder which is arranged on the fixed shield and the axis of which is parallel to the chute, the piston rod of cylinder with the dodge gate links to each other, still be equipped with in the fixed guard shield and be used for detecting the proximity switch of dodge gate position. Therefore, what the guard gate detection device adopted among the above-mentioned protector is that iron inductive switch detects opening or closing of guard gate, drives the guard gate action through the cylinder simultaneously so that the guard gate up-and-down motion, but when mechanical fault such as cylinder gas leakage appears or iron fillings splash and cause proximity switch to produce the error signal, can arouse the guard gate to produce the error action, and then lead to the risk that the manipulator collided the machine.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned prior art, the to-be-solved technical problem of the utility model lies in providing a gear chamfer iron fillings protector for block that iron fillings splash and do not interfere the manipulator action.

For solving the technical problem, the utility model provides a gear chamfering iron fillings protector, include the support with pillar fixed connection on the gear hobbing machine, be equipped with the hole of stepping down that is used for the manipulator to pass through on the support, the downthehole fixed mounting that steps down has mechanical combination formula rodless cylinder and the protective assembly who is connected with the slider on the mechanical combination formula rodless cylinder, protective assembly can open or close the hole of stepping down, still install the magnetic induction switch on the outer wall of mechanical combination formula rodless cylinder, the magnetic induction switch with the magnetic ring response cooperation on the mechanical combination formula rodless cylinder body.

Preferably, the protection component comprises a connecting rod connected with a sliding block on the mechanical combination type rodless cylinder and two fan-shaped breast boards connected with the connecting rod, and the mechanical combination type rodless cylinder can drive the two fan-shaped breast boards to open or close the abdicating hole through the connecting rod.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through the outer wall mounting magnetic induction switch at mechanical convolution rodless cylinder, can with the magnetic ring response cooperation on the rodless cylinder body piston like this, make the opening and shutting of protection component and the chamfering process synchronous to a large amount of iron fillings that splash and the wrong action of solving the guard gate that arouses because of cylinder mechanical failure when can effectively blockking the chamfering, and then stop the risk of colliding because of manipulator wrong action causes.

2. Through setting up protection component into the structure that can fan-shaped open and shut, can improve protection component's the speed of opening and shutting and gear machining efficiency like this.

Drawings

FIG. 2 is a diagram showing the positional relationship between the present invention and the robot;

illustration of the drawings: the mechanical arm comprises a mechanical arm 1, a clamping jaw 2, a support 3, a abdication hole 31, a protection component 4, a mechanical combination type rodless cylinder 5, a main shaft 6 and a tray 7.

Detailed Description

The invention will be further described with reference to the drawings and preferred embodiments.

As shown in fig. 1 and 2, the utility model relates to a gear chamfering iron chip protection device, including support 3, this support 3 is steel frame construction, its accessible hinge and the pillar fixed connection on the gear hobbing machine. The support 3 is provided with a yielding hole 31, and the position of the yielding hole 31 corresponds to the positions of the manipulator 1 and the spindle 6, so that the manipulator 1 can pass through the yielding hole 31 conveniently. The mechanical combined rodless cylinder 5 is fixedly arranged in the abdicating hole 31, so that the installation space of the cylinder can be saved, and the stroke of the cylinder can be reduced.

The outer wall of the mechanical combination type rodless cylinder 5 is also provided with a magnetic induction switch (drawn in the figure), and the magnetic induction switch can be in induction fit with a magnetic ring on the body of the mechanical combination type rodless cylinder 5, so that the opening and closing of the protection assembly and the chamfering process are synchronous.

The utility model discloses a work flow as follows:

two workpieces to be processed are grabbed by the claw 2 on the mechanical arm 1 from the tray 7 and moved to a feeding position of a main shaft 6 of the hobbing machine, one workpiece is installed on the main shaft 6 through the abdicating hole 31 by the mechanical arm 1, the hobbing process is sealed and processed on the hobbing machine, after the hobbing process is completed, the main shaft 6 is exchanged, the hobbing process is performed on the other workpiece, the workpiece for completing the hobbing is converted to the chamfering process, the mechanical arm 1 retreats at the moment, the abdicating hole 31 is closed by the protective component 4, and the workpiece for the chamfering process is processed in a closed state.

The utility model discloses influence the production environment because of a large amount of iron fillings that splash when can effectively solving gear chamfering process, and can prevent that iron fillings from splashing and arousing the problem that the manipulator produced the malfunction on the manipulator switch.
