Abstract
The utility model discloses a pusher provided with an electromagnetic maintaining device. The pusher comprises a motor, wherein a rotating shaft of the motor extends into a pusher casing, an impeller is arranged on the rotating shaft, and a piston is arranged in the pusher casing at the upper part of the impeller; a piston rod connected to the piston penetrates through the pusher casing and is fixedly connected with a push rod; a lower supporting plate is fixed at the lower part of the pusher casing, an upper supporting plate is arranged at the upper part of the pusher casing, and the upper supporting plate and the lower supporting plate are connected through fastening bolts; an electromagnet is arranged on the bottom surface of the upper supporting plate, and a switch striking plate is arranged on the side surface of the upper supporting plate; an electromagnetic chuck is arranged at the top of the push rod, and a stroke display switch is arranged on the side surface, corresponding to the electromagnetic chuck, of the switch striking plate; and the electromagnet and the pusher are independently arranged in a loop in parallel, so that safety is realized.
Description
Technical field
The utility model belongs to drive unit, relates in particular to a kind ofly be used to the pusher that works long hours, and is usually used in industrial break, pushing, fields such as clamping.
Background technique
Traditional pusher is power source with conventional motor, start the back just with specified rotating speed operation, and pusher just need be kept always after opening, this moment, motor still moved with specified rotating speed, this moment, motor will generate heat, and had namely increased the life-span that energy loss has reduced motor again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of pusher that has the electromagnetism holding means is provided, increased an electromagnetism holding means on the basis of traditional pusher, this device is simple, energy-conservation, easy to maintenance can independent operating outside pusher, increase the life-span of pusher.
For achieving the above object, the utility model is by the following technical solutions:
A kind of pusher that has the electromagnetism holding means, comprise motor, the rotating shaft of motor extend in the pusher casing, rotating shaft is provided with impeller, in the pusher casing of upper impeller, be provided with piston, be connected that piston rod on the piston passes the pusher casing and push rod is connected, at the pusher casing lower supporting plate is arranged fixedly, be provided with upper backup pad on pusher casing top, be connected by clamping bolt between upper backup pad and the lower supporting plate, the bottom surface of upper backup pad is provided with electromagnet, be provided with switch in the side of upper backup pad and hit plate, top at push rod is provided with electromagnetic chuck, and the side of hitting the corresponding electromagnetic chuck of plate with switch is provided with the stroke display switch.Electromagnet and pusher are connected in parallel in the loop, independent, safer each other.
The above-mentioned pusher that has the electromagnetism holding means, described lower supporting plate is by being bolted on the pusher casing.
The above-mentioned pusher that has the electromagnetism holding means, described clamping bolt are four, evenly are arranged between upper backup pad and the lower supporting plate.Directly four clamping bolts that play the support effect are welded on the lower supporting plate, and then with whole dunnage and hinged the tightening of pusher casing clamping bolt, saved installing space.
Adopt technique scheme, the utility model has following advantage: electromagnet directly is fixed on the upper backup pad on pusher push rod top, pusher push rod and electromagnetic chuck are connected as a single entity, pusher starts, and electromagnet is kept, and also can use separately, the electromagnet holding power is little, it is little to generate heat, and long service life is more energy-conservation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of pusher that has the electromagnetism holding means as shown in Figure 1, comprise motor 1, the rotating shaft of motor 1 extend in the pusher casing, rotating shaft is provided with impeller 2, in the pusher casing of upper impeller, be provided with piston 3, be connected that piston rod on the piston passes the pusher casing and push rod 4 is connected, at the pusher casing lower supporting plate 12 is arranged fixedly, be provided with upper backup pad 6 on pusher casing top, be connected by clamping bolt 11 between upper backup pad 6 and the lower supporting plate 12, upper backup pad 6 is fixed on the clamping bolt 11 by nut 5, the bottom surface of upper backup pad 6 is provided with electromagnet 8, be provided with switch in the side of upper backup pad 6 and hit plate 7, be provided with electromagnetic chuck 10 at the top of push rod 4, the side of hitting the corresponding electromagnetic chuck 10 of plate 7 with switch is provided with stroke display switch 9.Electromagnet and pusher are connected in parallel in the loop, independent, safer each other.
Lower supporting plate 12 of the present utility model is by being bolted on the pusher casing, and clamping bolt 11 is four, evenly is arranged between upper backup pad and the lower supporting plate.Directly four clamping bolts that play the support effect are welded on the lower supporting plate, and then with whole dunnage and hinged the tightening of pusher casing clamping bolt, saved installing space.
Working principle: motor and electromagnet are switched on simultaneously, impeller motor is by 2 rotations of back impeller, producing oil pressure forces piston 3 upwards to push away, under electromagnetism and pusher act on simultaneously, electromagnetic chuck 10 upwards is pushed into the stroke of the volume of reaching, stroke display switch 9 hits plate 7 with switch and contacts, tutorial light is bright, and the electricity of pusher is broken, and by electromagnetic action electromagnet is firmly held, tutorial light is bright, just illustrate that pusher is in open mode, because electromagnet and pusher push rod are one, the volume push rod is hinged with driven parts again, effect by electromagnetism is fixed on specified height with push rod, and just break is in running order always.The outage rear push-rod resets.Thereby realize that pusher starts, electromagnet is kept.It is few that electromagnet is kept the low heating of electric current, can keep for a long time.
