Abstract

The utility model relates to a processing clamp suitable for large-scale thin-plate workpieces. The processing clamp is characterized by the inclusion of a bottom plate and a main plate which is perpendicular to and integrated with the bottom plate, wherein supporting plates are connected between the bottom plate and the main plate; a plurality of locating grooves are formed on the lower surface of the bottom plate; a plurality of T-shaped grooves which are parallel to one another are formed on the outer side surface of the main plate; threaded holes in an orderly arrangement are formed among the T-shaped grooves; workpiece pressure measuring plates are arranged on the outer side surface of the main plate and fixedly connected to the T-shaped grooves or the threaded holes; a row of threaded holes are formed on the top surface of the main plate; and workpiece upper pressure plates are fixedly connected to the threaded holes on the top surface of the main plate through dual-head screw rods. In the utility model, the locating grooves are formed on the bottom plate and can be matched with the T-shaped grooves on a working table to achieve an accurate positioning effect; the workpiece upper pressure plates and the workpiece pressure measuring plates, which are respectively arranged at the top and on the side surface of the main plate, can be conveniently used for clamping a workpiece and are convenient to operate; and the plurality of T-shaped grooves and the orderly threaded holes among the T-shaped grooves are formed on the side surface of the main plate, which can meet the requirements of processing workpieces in a wider range of size.

Description

A kind of clamp for machining that is applicable to large-scale sheet type workpiece

Technical field

The utility model relates to a kind of jig, particularly a kind of be applicable to large-scale sheet type workpiece clamp for machining.

Background technology

At present, large-scale sheet type workpiece is prevalent in a lot of fields such as lathe, hydraulic test, generally need process for this class part at large-scale numerical control boring-mill work center, but, general clamp for machining clamps because being difficult to that such part is erect the location, even if can locate clamping, machining accuracy can not reach requirement.

Summary of the invention

The utility model provides a kind of positioning accuracy height for solving the technical problem that exists in the known technology, easy operating, and can satisfy the clamp for machining that is applicable to large-scale sheet type workpiece that large-scale workpiece is processed in the broad size range.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of clamp for machining that is applicable to large-scale sheet type workpiece, it is characterized in that: the mainboard that comprises base plate and perpendicular one, be connected with gripper shoe between base plate and the mainboard, on the described base plate lower surface several locating slots are set, the T type groove that several are parallel to each other is set on the lateral surface of described mainboard, the neat screwed hole of arranging is set between the T type groove etc., workpiece pressure measurement plate is set on the lateral surface of described mainboard, the pressure measurement plate fixedly is connected in T type groove or screwed hole; The end face of mainboard is provided with row's screwed hole, and the workpiece top board fixedly is connected in the screwed hole of mainboard end face by double threaded screw.

Advantage and the good effect that the utlity model has are: be provided with and the corresponding locating slot of workbench T type groove on the base plate of anchor clamps, can carry out accurate localization to anchor clamps, thereby guarantee the positioning accuracy of workpiece work in-process; In the side of mainboard the workpiece side pressing plate is set, the end face of mainboard is provided with the workpiece top board, and workpiece is close to the mainboard side, adjust to suitable height after, compress top board and pressure measurement plate, just can position clamping to workpiece easily; The screwed hole of neat arrangements such as being provided with between several T type grooves and the T type groove is set in the side of mainboard, can carries out flexible positioning to it according to shape, the size of workpiece, the location of satisfying workpiece in the broad size range clamps.

Among the figure: the 1-base plate; The 2-mainboard; 3 gripper shoes; The 4-locating slot; 5-T type groove; The 6-screwed hole; 7-workpiece side pressing plate; The 8-screwed hole; 9-workpiece top board; The 10-double threaded screw; 11-frock pad; 12-workpiece 13-lifting eye; The 14-workbench.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1-5, a kind of clamp for machining that is applicable to large-scale sheet type workpiece, comprise base plate 1 and with the mainboard 2 of the vertical one of base plate, be connected with gripper shoe 3 between base plate and the mainboard, several locating slots 4 are set on the base plate lower surface, this locating slot 4 is corresponding with the T type groove of platen, accurately connects by positioning key.The lateral surface of mainboard is the locating surface of workpiece, and the T type groove 5 that several are parallel to each other is set on this face, and the neat screwed hole of arranging 6 is set between the T type groove 5 etc.Workpiece pressure measurement plate 7 is set on the lateral surface of mainboard, and according to shape, the size of workpiece to be processed, pressure measurement plate 7 is connected in T type groove 5 or is fixed in above-mentioned screwed hole 6 by screw by bolting; End face at mainboard is provided with row's screwed hole 8, and workpiece top board 9 fixedly is connected in the screwed hole 8 of mainboard end face by double threaded screw 10.

In the present embodiment, base plate 1, mainboard 2 are the ironcasting of one with gripper shoe 3, blank artificial aging after roughing is handled, carry out fine finishining then, make on the base plate with the contact-making surface of platen, mainboard on flatness, the perpendicularity of locating surface of workpiece all reach 0.05mm, adopt the anchor clamps of above-mentioned high geometric accuracy, guarantee to be processed geometric accuracy.Anchor clamps adopt cast iron materials, absorb cutter and act on and impact on the workpiece and vibrations, and a nearly step guarantees the precision of workpiece, and because ironcasting is not yielding, guarantee anchor clamps high service life.In addition, because the volume and weight of anchor clamps is bigger,, the hole for hoist 13 of being convenient to mechanical handling is set on gripper shoe 3 for ease of conveying in sections.

Operation principle of the present utility model:

The lateral surface of to be processed 12 locating surface and anchor clamps mainboard 2 is close to, adjust the frock pad 11 between workbench 14 and workpiece 12 bottom surfaces, make workpiece 12 on workbench 14, reach a suitable position height, position, the workpiece top board 9 that will be connected in the mainboard top then is locked on the workpiece 12 with the workpiece side pressing plate 7 that is connected in the mainboard side, carries out the clamping of workpiece 12.

For the workpiece that can not locate with above-mentioned anchor clamps, can in the scope that platen allows,, position clamping, thereby guarantee the processing of large-scale workpiece in the broad size range workpiece with the combination of the anchor clamps more than two.
