Technical field
The utility model relates to a kind of Work-sheet pressing frock, especially relates to a kind of hold down gag that adopts leading screw to come workpiece pressing.
Background technology
At present, most workpiece pressuring clamping device has cylinder, oil cylinder, jack etc. to compress device.The Work-sheet pressing that air-cylinder compressing device is applicable in batches greatly, thrust is little; The Work-sheet pressing that oil cylinder gag is applicable in batches greatly, thrust is large; The jack hold down gag is applicable to the production that thrust is large, batch is little.And for the product of the many kinds of small lot, the workpiece that Work-sheet pressing power is little, use cylinder, oil cylinder, jack hold down gag cost of manufacture is high, the cycle is long and often need to often changes briquetting because of the change of seal face, need badly further and improved.
The utility model content
The purpose of this utility model is to overcome that common hold down gag cost of manufacture is high, the cycle is long and often need often to change the defective of briquetting because of the change of seal face, propose a kind of simple in structure, easy to operate, compress effective workpiece pressuring clamping device.
In order to realize above-mentioned utility model purpose, the technical solution adopted in the utility model is: a kind of workpiece pressuring clamping device, comprise leading screw, nut and base, and described nut is fixed on the base top, described leading screw and nut are adaptive, and screw and nut that leading screw passes nut link together; Workpiece is placed on the base, and the part that needs are compressed places under the nut, by rotating threaded shaft workpiece is progressively compressed.
As further improvement of the utility model, described nut and base are connected and fixed by gantry or semi-gantry.
As further improvement of the utility model, the lower end of described leading screw is provided with a briquetting.
As further improvement of the utility model, described leading screw is processed as bottom sphere and simultaneously is provided with screw thread in the circumference side of leading screw lower end, offers groove on the briquetting in addition, and it is adaptive that groove inner periphery side offers the screw thread of screw thread and leading screw lower end.
As further improvement of the utility model, also offer an escape larger than groove tapped bore in the described briquetting groove, the degree of depth of described escape adds that greater than screw mandrel sphere action wire rod thread is long, after briquetting all screws in, screw thread has been to make leading screw and briquetting not allow segregative effect, briquetting can rotate around screw spherical, realizes compressing all seal faces and comprises the inclined-plane.
As further improvement of the utility model, the screw thread of the circumference side of described leading screw lower end is external screw thread, and the screw thread of groove inner periphery side is internal thread, and it is secondary that described internal thread and external screw thread form self-locking thread, guarantees that briquetting and leading screw can not come off
As further improvement of the utility model, described gantry or semi-gantry one end and nut-welding are fixed, other end welding or use bearing pin or be bolted on the base.
As further improvement of the utility model, described base also comprises a workpiece placement saddle.
In sum, a kind of workpiece pressuring clamping device of the utility model has been realized that apparatus structure is simple, easy to operate, has been compressed effective purpose.
Description of drawings
Fig. 1 is the structural representation of a kind of workpiece pressuring clamping device of present embodiment;
