Description

A kind of magnetic clamp
Technical field
The utility model relates to clamping device field, especially relates to magnetic clamp field.
Background technology
Current clamping device great majority are all to provide chucking power by motor, cylinder, or provide chucking power by spring etc., and the shortcoming of these mechanisms is complex structures, and use is inconvenient, cost is higher.As in use there is the problems such as fatigue fracture in spring, thus the life-span that causes clamping device.
Chinese patent technology discloses a kind of similar magnetic clamp, its technical scheme is: a kind of magnetic chuck, comprise left and right clamp and the pin of collet body, collet body bottom, a magnetic material is respectively housed on the clamp of described left and right, two magnetic material homopolarities are relative, and collet body and left and right clamp outer is arranged with a chuck cover to slide up and down along collet body and left and right clamp only.But this fixture only has pair of magnetic material pair, well do not utilize the characteristic of magnetic material.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, easy to use, with low cost, change the convenient and high magnetic clamp of production efficiency.
In order to solve above-mentioned technical problem, basic technical scheme of the present utility model is: a kind of magnetic clamp, comprise fixture stand and chuck, described chuck comprises respectively has one end to be installed on stationary clamp and the adjustable cramp in fixture stand, first magnetic material of the each installation of retaining part inner surface of described stationary clamp and adjustable cramp, one end that described adjustable cramp is installed in fixture stand is movably installed in this fixture stand by pin;
Described the first magnetic material heteropole is relative;
Described stationary clamp and adjustable cramp are installed on second magnetic material of the each installation in one end in fixture stand, and this second magnetic material homopolarity is relative;
The side of the retaining part of described adjustable cramp is provided with projection.
Further illustrate, the retaining part front end of described adjustable cramp has groove, and the position that the retaining part of described stationary clamp is corresponding with groove is provided with projection.
Further illustrate, the thickness of its retaining part of Thickness Ratio that described adjustable cramp is installed on the part in fixture stand is little, and the excessive position of this part and retaining part is provided with pin hole.
Further illustrate, upper surface and the lower surface of near the adjustable cramp described pin hole are arc-shaped curved surface.
Further illustrate, described stationary clamp stiff end is provided with bolt hole, its be bolted with fixture stand on.
Further illustrate, described bolt hole is two.
Further illustrate, described fixture stand is cross fixture stand, and it can install four pairs of chucks simultaneously.
The beneficial effects of the utility model are: provide a kind of simple in structure, chucking power is moderate can not accelerate part, and production cost is low, changes convenient and swift.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model magnetic clamp;
The chuck structure schematic diagram of Fig. 2 the utility model magnetic clamp.
The specific embodiment
Below in conjunction with accompanying drawing 1, the utility model is described further, but should limit protection domain of the present utility model with this.For convenience of description, below, said left, right, up, down etc. is with the orientation shown in Fig. 1.
As shown in Figure 1, this magnetic clamp includes a cross fixture stand 1, the four direction of this cross fixture stand 1 all with distribute four for the square hole 11 of chuck is installed.The middle part of this cross fixture stand 1 is cylinder form, has axis hole 12 in this columniform axle center, is evenly distributed with four screw holes 13 near of axis hole 12.Described axis hole with screw hole 13 for being connected outside rotation motor.
In Fig. 1, include four chucks, state with the chuck on Fig. 1 the right below.
Shown in Fig. 1, this chuck comprises stationary clamp 2 and adjustable cramp 3.The stiff end (being the left in Fig. 1, the top of Fig. 2) of described stationary clamp 2 is provided with the first magnetic material 4 with the left end in diagram of adjustable cramp 3, and these the first magnetic material 4 homopolarities are relative.Be provided with the second magnetic material 5 in the appropriate location of the clamping part of stationary clamp 2 and adjustable cramp 3, these the second magnetic material 5 opposite sex relatively.The first described magnetic material 4 and the second magnetic material 5 are permanent magnet.What deserves to be explained is, in the side of the retaining part of adjustable cramp 3, strip projection 33 is set.
The stiff end of described stationary clamp 2 is provided with two bolts hole 21, corresponding, also has two bolts hole 111 on the square hole 11 of cross fixture stand 1, and described stationary clamp 2 is secured by bolts on the bolt hole 111 in this square hole 11.
In addition, as shown in Figure 1 and Figure 2, the left-of-center position of described adjustable cramp 3 has pin hole 31, correspondingly on the square hole 11 of cross fixture stand 1, has the pin hole that shows direction perpendicular to Fig. 1, utilizes pin that adjustable cramp 3 is connected in square hole 11 actively.Improve as one, the thickness of the left end of the pin-and-hole 31 of described adjustable cramp 3 is less than the thickness of its retaining part, and little more many to the distance of the bottom surface of stationary clamp 2 than square hole 11 bottom surfaces, and guarantee adjustable cramp 3 is around pin activity like this.As another improvement, lower surface and upper surface near the pin hole 31 of adjustable cramp 3 are circular arc camber, so just make adjustable cramp 3 rotate and are more prone to.
To further illustrate, in order clamping conveniently, to have groove 32 at the retaining part front end of described adjustable cramp 3, the position that the retaining part of described stationary clamp 2 is corresponding with groove 32 is provided with projection 22.
When work, what cross fixture stand 1 was shown by Fig. 1 under the effect of motor rotates counterclockwise, in the time turning to the position that need to clamp part, it is the position of the right chuck shown in Fig. 1, Fig. 2, the strip projection that is now positioned at the retaining part of adjustable cramp 3 will be encountered mechanical projection, chuck is opened, i.e. state shown in Fig. 1.Now, the horizontal air cylinder that is installed on this cross fixture stand 1 is by the motion of turning right of whole drive cross fixture stand 1, and parts are placed in to the groove 32 of adjustable cramp 3, the strip projection 33 that is now fixed on adjustable cramp 3 will depart from mechanical projection, under the repulsive force of the first magnetic material 4 and the attraction effect of the second magnetic material 5, stationary clamp 2 and adjustable cramp 3 closures, parts are clamped, now motor continues to drive cross fixture stand 1 to continue rotation, and horizontal air cylinder will drive this cross fixture stand 1 to reset simultaneously.Like this, repeat above step, guarantee the work of this magnetic clamp.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
