The utility model discloses a bottom plate, first fixed plate and the second fixed plate of setting on the bottom plate, wherein, be equipped with the first recess of a plurality of on the first fixed plate, the second fixed plate correspond the position with first recess and be equipped with the second recess, first recess and second recess cooperation are pressed from both sides tightly and are waited to process the work piece, still be equipped with the locking device with locking between first fixed plate and the second fixed plate on first fixed plate and the second fixed plate.

The utility model discloses make further improvement, first fixed plate and second fixed plate bottom relative position are provided with keeps away the dead slot.

The utility model discloses make further improvement, the bottom plate is for adsorbing the electromagnet who treats the processing work piece, still have switch electromagnet's switch on the bottom plate.

The utility model discloses make further improvement, be equipped with the mounting hole on the electromagnet, electromagnet's switch setting is in the mounting hole, the mounting hole outside is equipped with operating switch's handle.

The utility model discloses make further improvement, the handle is interior hexagonal spanner.

The utility model discloses make further improvement, locking device is including setting up hexagon socket head cap screw on first recess and second recess both ends and cup jointing the spring on hexagon socket head cap screw, the spring sets up between first fixed plate and second fixed plate.

Compared with the prior art, the beneficial effects of the utility model are that: the end face grinding device is simple in structure, low in cost, capable of simultaneously clamping a plurality of workpieces (such as small thimbles) and then grinding the end face on the surface grinding machine, reliable in clamping, high in clamping efficiency, particularly suitable for mass production clamping, and strong in practicability.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1, the technical problem solved by the utility model is that require the reliable technical problem of clamping and can once clamp a plurality of work pieces when processing the both ends face of small-size cylinder work piece (for example little thimble) on the plane mill bed, this example includes electromagnet 1, sets up first fixed plate 3 and second fixed plate 7 on electromagnet 1, wherein, be equipped with the first V type groove of a plurality of on the first fixed plate 3, the second fixed plate 7 with first V type groove correspond the position and be equipped with the second V type groove, first V type groove and the cooperation of second V type groove press from both sides a plurality of work pieces 4 of waiting to process simultaneously still be equipped with the locking device with locking between first fixed plate 3 and the second fixed plate 7 on first fixed plate 3 and the second fixed plate 7. The first groove and the second groove in this embodiment may also be other groove structures capable of clamping the thimble structure.

The electromagnetic chuck 1 is also provided with a switch for switching the electromagnetic chuck 1, the electromagnetic chuck 1 is provided with a mounting hole, the switch of the electromagnetic chuck is arranged in the mounting hole, and the outer side of the mounting hole is provided with a handle 5 for operating the switch. The handle 5 in this example is a socket wrench. Similarly, the locking device of this example comprises socket head cap screws 8 arranged at two ends of the arrangement direction of the plurality of first V-shaped grooves and the plurality of second V-shaped grooves, and springs 2 sleeved on the socket head cap screws, wherein the springs 2 are arranged between the first fixing plate 3 and the second fixing plate 7.

When a workpiece is clamped, an inner hexagonal wrench is used for pulling a switch of an electromagnetic chuck to enable a magnetic table to be non-magnetic, then a first inner hexagonal screw 8 and a second inner hexagonal screw 6 on a second fixing plate 7 are unscrewed, the two fixing plates naturally open under the action of the elastic force of a spring 2, the workpiece 4 to be machined is manually placed into a V-shaped groove one by one and then the first inner hexagonal screw 8 and the second inner hexagonal screw 6 are locked, the workpiece is reliably positioned and clamped, then the inner hexagonal wrench is used for pulling the switch of the electromagnetic chuck 1 to enable the magnetic table to have a magnetic suction clamping jig, the clamping jig is simple in structure, low in cost, capable of simultaneously clamping a plurality of workpieces (such as small thimbles) and then grinding end faces on a surface grinding machine, reliable in clamping, high in clamping efficiency, particularly suitable for. In addition, the hexagon socket head wrench can be operated the switch locking device of the electromagnetic chuck 1 simultaneously, and when not in use, the switch locking device is fixed in the mounting hole, is not easy to lose, is convenient for material taking and is convenient to operate.

Preferably, clearance grooves 9 are formed in the opposite positions of the bottoms of the first fixing plate 3 and the second fixing plate 7, and in this embodiment, the adjacent bottom surfaces of the first fixing plate 3 and the second fixing plate 7 are perpendicular to the side surfaces and are provided with the clearance grooves 9 at 90 degrees, so that the clearance grooves can avoid the support part of the workpiece 4 to be processed when the workpiece is clamped.

The above-mentioned embodiments are the preferred embodiments of the present invention, and the scope of the present invention is not limited to the above-mentioned embodiments, and the scope of the present invention includes and is not limited to the above-mentioned embodiments, and all equivalent changes made according to the present invention are within the protection scope of the present invention.
