Abstract

A kind of controllable sucker device with permanent magnet includes: a permanent magnet, an external frame arranged outside the permanent magnet, a cylinder whose piston is connected with the permanent magnet, a cylinder tube of the cylinder which is connected with the back-end of the frame. The utility model combines the force of compressed air and the control of magnetic adsorption, not only to overcome the high requirements of vacuum sucker device towards the surface of the objects to be snatched in the prior technology, but also to overcome the problem of easy grasp and difficult release when the permanent magnet adsorbs the ferromagnetic objects.

Description

The controllable permanent magnetic Acetabula device

Technical field

The utility model relates to a kind of Acetabula device, particularly relates to a kind of controllable permanent magnetic Acetabula device.

Background technology

The action of present industrial utilization absorption class realizes two kinds of structures are mainly taked in the extracting of object and the Acetabula device of release: a kind of is that vacuum cup is adsorbed on body surface, and another kind is to adsorb ferromagnetic object with electromagnet.Wherein, the against vacuum sucker structure, require to have on the crawled body surface area enough greatly, comparatively level and smooth and air-tightness crawl position preferably.Be difficult to find such position if grasp by crawled object surfaces, just be difficult to realize grasping; Another kind of structure for electromagnet need provide continual electric energy, and power consumption is high.Except heating and electrical safety problem, in case take place to have a power failure or fault, crawled object falls down easily immediately.Therefore use dangerous.If simply utilize permanent magnet that ferromagnetic object is adsorbed, because difficult control release is grasped in having or not of difficult control magnetic though then be easy to realization.

Summary of the invention

The purpose of this utility model is had relatively high expectations to crawled object surfaces in order to overcome above-mentioned Acetabula device, and the defective of using dangerous and difficult control to discharge provides a kind of controllable permanent magnetic Acetabula device that utilizes compressed air-driven.

To achieve the above object, the technical scheme that the utility model adopted is: it comprises: permanent magnet places the outer housing of permanent magnet, the cylinder that piston and permanent magnet link together, the cylinder barrel of the cylinder that links together with outer back end of frame.

As above-mentioned structure, when using the utility model controllable permanent magnetic Acetabula device to grasp crawled object, at first be to hold crawled object by permanent magnet, finish grasping and transporting of task; In the time will discharging crawled object, start cylinder, the piston of cylinder drives the permanent magnet that links together with it and moves backward, the housing that makes rear end and cylinder barrel link together backs down the crawled object that is attracted on the permanent magnet, crawled object loses the power of being adsorbed, and also just has been released.

The beneficial effects of the utility model are remarkable.Because it comprises permanent magnet and cylinder simultaneously,, finish grasping and transporting of task with the crawled object of permanent magnet absorption; With cylinder permanent magnet is drawn back from crawled body surface, realize release movement.The utility model is that the control with the absorption of compressed-air power and magnetic combines, both overcome formerly that vacuum chuck device has higher requirement to crawled object surfaces in the technology, overcome permanent magnet absorption ferromagnetism again and grasped easily, discharged difficult problem.And permanent magnet need not electrification, and is safe and reliable, in a large number the conservation of power energy.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of the utility model when grasping crawled object;

Fig. 3 is the schematic diagram of the utility model when discharging crawled object;

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is further described.

The utility model controllable permanent magnetic Acetabula device comprises as shown in Figure 1: permanent magnet 2 places the outer housing 3 of permanent magnet, the cylinder 5 that piston 4 and permanent magnet 2 link together, the cylinder barrel 6 of the cylinder 5 that links together with housing 3 rear ends.

The housing 3 that described rear end and cylinder 5 cylinder barrels 6 link together can be the biside plate that is parallel to each other, or cylinder, or the framework that is made of side plate.Because the piston 4 of cylinder 5 drives permanent magnets 2 and moves forward and backward, make that the front end face 301 of housing 3 can be lower than, flush in or be higher than the adsorption plane 201 of permanent magnet 2.

As shown in Figure 2, when the utility model controllable permanent magnetic Acetabula device will grasp crawled object spare 1, the front end face 301 of housing 3 is lower than (or flush in) permanent magnet 2 adsorption planes 201, then permanent magnet 2 adsorption planes are close on the surface of crawled object 1, hold crawled object firmly, finish grasping and transporting of task;

As shown in Figure 3, after the task of finishing carrying, when needing to discharge crawled object 1, start cylinder 5, move behind the piston 4, this moment, housing 3 withstood crawled object 1 surface, make permanent magnet 2 with respect to crawled object 1 away from, magneticaction weakens rapidly, has finished the task of discharging crawled object 1 of installing.

Claims

1. controllable permanent magnetic Acetabula device, it comprises: permanent magnet is characterized in that comprising the housing that places permanent magnet outer, the cylinder that piston and permanent magnet link together, the cylinder barrel of the cylinder that links together with outer back end of frame.

2. controllable permanent magnetic Acetabula device according to claim 1 is characterized in that the housing that described rear end and cylinder barrel link together is the biside plate that is parallel to each other, or cylinder, or the framework that is made of side plate.
