Abstract

The utility model discloses a chamfering machine protecting device. The chamfering machine protecting device comprises a guide rail and a sliding seat. The sliding seat is driven by a pushing mechanism to slide left and right along the guide rail, a big spring is connected between the front end of the top portion of the sliding seat and a box body of a chamfering machine, and under a normal condition the sliding seat is arranged at the front end of the guide rail and enables the spring to be in a tensioning state. The sliding seat is provided with a through hole penetrating through the sliding seat, a material pushing ejector rod penetrates through the through hole and can slide left and right along the sliding seat in the through hole, the front end of the material pushing ejector rod and the rear end of the top portion of the sliding seat are connected with a small spring which is in a natural state under a normal condition, and an approaching switch is further arranged on one side of the sliding seat. When a breakdown occurs, the material pushing ejector rod can overcome the acting force of the small spring and enables a material pushing guide rod to move in the direction opposite to the feeding direction. Due to the structure of the chamfering machine protecting device, a lifting workbench is prevented from running still when workpieces do not reach a position, and the situation of damaging workpieces and tools is avoided, and the chamfering machine protecting device performs the function of protecting the workpieces and the tools, and improves processing efficiency.

Description

The beveler protective device

Technical field

The utility model relates to a kind of beveler protective device, belongs to the Machining Technology field.

Background technology

Existing beveler comprises a feed mechanism and a chamfer mechanism, and feed mechanism is delivered to self-powered platform with workpiece from workbench, then by the self-powered platform of chamfer mechanism workpiece is delivered to machining position, by emery wheel workpiece is carried out chamfering; Existing this beveler is in feeding process; tend to exist workpiece by clamping stagnation and the phenomenon that feeding is not in place; need to be at the corresponding protective device of set-up of control system; the running protection of common automatic system was controlled by the PC adjusting time; the guard time that PC regulates has one period time delay with respect to the effect of feed mechanism; therefore when feeding is not in place, the workpiece that self-powered platform continuation action will not put in place thus headed into emery wheel, causes the damage of workpiece and frock.

Summary of the invention

The technical problems to be solved in the utility model provides a kind ofly can carry out stoppage protection control, the fast beveler protective device of reaction speed to equipment when feeding is not in place at workpiece.

In order to solve the problems of the technologies described above, beveler protective device of the present utility model, comprise the guide rail that is arranged on beveler casing one side and the slide that is arranged on the guide rail and can moves forward and backward, be connected with one between slide and the beveler casing and can drive the big spring that slide moves forward; Also be equipped with on the casing and can drive the power set that slide moves backward; Be provided with a through hole that vertically runs through slide on the slide, pusher push rod that is used for pushing workpiece passes through hole and can relatively slide before and after the slide in through hole, be connected with a little spring between pusher push rod and the slide, the pulling force of little spring makes the pusher push rod move forward to limited extreme position; Be provided with an approach switch that is connected in the beveler control circuit on the slide, the active force that the pusher push rod overcomes little spring can trigger approach switch when slide moves backward.

Described power set comprise one by motor-driven cam, and one of cam driven is hinged on the swing arm swing on the casing, and the swing arm upper end can drive slide when swinging backward mobile backward.

After adopting above-mentioned structure; because the big spring that arranges and little spring and the pusher guide rod that can in slide, horizontally slip; under the relation that between them, cooperatively interacts; when feeding is not in place; the pusher guide rod can move and trigger approach switch toward the opposite direction of feed direction; and send instruction by approach switch and realize in real time control; having avoided thus self-powered platform not put in place at workpiece still moves; cause the generation of the damaged condition of workpiece and frock; play the effect of protection workpiece and frock, also improved working (machining) efficiency.

Description of drawings

Fig. 2 material-pulling device plan structure of the present utility model schematic diagram.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, beveler protective device of the present utility model is described in further detail.

As shown in the figure, beveler protective device of the present utility model comprises the guide rail 2 that is arranged on beveler casing 1 one sides and the slide 7 that is arranged on the guide rail and can moves forward and backward, and is connected with one between slide 7 and the beveler casing 1 and can drives the big spring 3 that slide moves forward; Also be equipped with on the beveler casing 1 and can drive the power set that slide moves backward; Be provided with a through hole that vertically runs through slide on the slide, pusher push rod 4 that is used for pushing workpiece passes through hole and can slide before and after slide in through hole, be connected with a little spring 5 between pusher push rod and the slide, the pulling force of little spring 5 makes pusher push rod 4 move forward to limited extreme position; Be provided with an approach switch 6 that is connected in the beveler control circuit on the slide 7, the active force that pusher push rod 4 overcomes little spring can trigger approach switch 6 when slide 7 moves backward.

Described power set comprise one by motor-driven cam 12, and one of cam driven is hinged on swing arm 11 swings on the casing, and the swing arm upper end can drive slide 7 when swinging backward mobile backward.

Operation principle is as follows:

Under the state of not starting working, cam 12 is pressed over the lower end of swing arm 11, retreats by swing arm 11 driving slides 7 and pusher push rod 4, and this moment, big spring 3 was in tensioning state;

When needs push workpiece, cam 12 rotates, driving the swing arm upper end swings forward, make slide 7 and pusher push rod 4 under the effect of big spring 3, move and promote workpiece to self-powered platform to feed direction, then by the self-powered platform of chamfer mechanism workpiece is delivered to machining position, by emery wheel workpiece is carried out chamfering;

Be that workpiece is when blocking when breaking down; pusher push rod 4 withstands on the workpiece 13 and can not move forward; and still forward operation under the big spring effect of slide; thereby the relative slide of active force that makes the pusher push rod overcome little spring 5 slides backward; thereby triggering approach switch; it is out of service to send the signal self-powered platform by approach switch; having avoided thus self-powered platform not put in place at workpiece still moves; cause the generation of the damaged condition of workpiece 13 and frock; play the effect of protection workpiece and frock, also improved working (machining) efficiency.
