Description

A kind of improved powerful electromagnetic chuck

The utility model relates to a kind of powerful electromagnetic chuck, and resistance is less when referring to a kind of pressurization especially, and the powerful electromagnetic chuck with multiple function.

As depicted in figs. 1 and 2, powerful electromagnetic chuck commonly used is to establish a screw rod 2 at the center of a sucker 1, other establishes a conjunction 3, this conjunction 3 is a lid, its inner top surface central position is provided with one and screws togather seat 4, end face at conjunction 3 is provided with a hook 5 in addition, the screw rod 2 that screws togather seat 4 and sucker 1 of conjunction 3 is screwed togather, can make conjunction 3 and sucker 1 screw togather fastening, and the week edge that makes conjunction 3 is pressed against the edge of the end face of sucker 1, so that conjunction 3 compresses sucker 1, make sucker 1 adsorbed close on absorbate.But because the hook 5 of this powerful electromagnetic chuck commonly used is installed on the conjunction 3, therefore when the week of conjunction 3, the edge was pressed on the end face edge of sucker 1, hook 5 might not just in time make progress, possible deflection or inversion, and at this moment, hook 5 just can't be used.If want hook 5 is upwards state then need become flexible conjunction 3, the adsorption force of sucker is reduced greatly, even drop.

In addition, because sucker 1 is soft plastic cement material, therefore when conjunction 3 was pressed on the sucker 1, frictional force between the two was very big, caused and used inconvenience.

The sectional view of another kind of commonly used powerful electromagnetic chuck is that the end face at the outer cover 6 of a central bore is provided with a hook 5 equally as shown in Figure 3, and outer cover 6 is inserted on the screw rod 2 of sucker 1, with a nut 7 outer cover 6 is tightened on the sucker 1, to increase the adsorption force of sucker 1 again.But it is because screw rod 2 protruding being exposed at outside the outer cover 6 of this powerful electromagnetic chuck, so attractive in appearance inadequately on the profile.

The purpose of this utility model is to provide a kind of frictional force little, easy to use, and has the powerful strong dish of multiple function.

The purpose of this utility model realizes by following technological means: a kind of improved powerful electromagnetic chuck, by sucker, joint bolt, compression element, lock firmware and conjunction are formed, the body portion of joint bolt has worm tooth, and joint bolt connects the central position that is installed in sucker, compression element is the disklike body that a center has screw, it is characterized in that: the end face week of sucker is along bottom surface convex edge mill pressured compel of the ring that is arranged with a low coefficient of friction material for compression element, the bottom end edge of compression element is to having the convex edge, lock firmware is the lid of a reservation shape, its inner top surface central position is provided with and screws togather seat, screws togather seat and is provided with conjunction.

Conjunction can be made up of the door knot part that a screw rod button top forms hook; Conjunction can be by a screw rod, and a clamping block and clamping ring are formed; Conjunction can be made up of pivot joint ear, socket, screw rod, fixing bolt, and articulating on the ear has perforation.

Advantage of the present utility model is: simple in structure, easy to use.
