Abstract
The invention discloses a height-adjustable clamping device and aims at solving the problem that the existing clamping device is only capable of clamping fixed-size workpieces and thus limited in use. The height-adjustable clamping device comprises a force application structure and a pressing plate, and also a support, wherein a center screw is arranged on the support, a locking nut is arranged on the bottom of the center screw, a connecting sleeve is arranged in threaded connection with the center screw in the circumferential direction of the center screw, an E-shaped snap ring is arranged on the outer part of the connecting sleeve, a through hole is formed in the middle part of the pressing plate, the inner diameter of the through hole is greater than the outer diameter of the connecting sleeve, the pressing plate penetrates through the outer part of the connecting sleeve, the pressing plate is connected with the connecting sleeve through a screw, a support disc is arranged in threaded connection with the center screw on the lower part of the pressing plate, a height adjusting nut is arranged on the lower part of the support disc, and a return spring is arranged between the pressing plate and the support disc. The clamping device is capable of clamping the workpieces of various sizes, and practical.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of height-adjustable clamping device.
Background technology
clamping device is widely used in the manufacture processing of workpiece, and at present, most of clamping devices can not regulate,
Workpiece that all can only clamping position fixed dimension, this is just restricted the use of clamping device; Meanwhile, the workpiece of sizes needs a plurality of different clamping devices, has also increased the cost of workpiece processing and manufacturing.
Summary of the invention
The invention provides a kind of height-adjustable clamping device, to solve existing clamping device, can only grip dimension workpiece, use limited problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Height-adjustable clamping device, comprise force application structure and pressing plate, also comprise bearing, bearing is provided with center bolt, the bottom of center bolt is provided with locking nut, being circumferentially threaded and being provided with adapter sleeve with center bolt at described center bolt, adapter sleeve outside is provided with E shape snap ring, middle part at described pressing plate has through hole, the internal diameter of described through hole is greater than the external diameter of described adapter sleeve, described pressing plate is arranged in the outside of adapter sleeve by described through hole, pressing plate and adapter sleeve are connected by screw, bottom at described pressing plate is threaded and is provided with supporting disk with center bolt, in supporting disk bottom, be provided with height adjusting nut, between described pressing plate and supporting disk, be provided with back-moving spring.
Beneficial effect of the present invention: this clamping device is because adapter sleeve is threaded with center bolt formula, therefore can be by regulating the height of adapter sleeve on center bolt, by adapter sleeve band dynamic pressure plate and supporting disk, moved up and down to coordinate the variation of workpiece different size height, realize the clamping position of different size workpiece.
Further, described force application structure comprises and is arranged on pressing plate one end cam that can offset with supporting disk and the action bars being connected with cam.This kind of force application structure effectively utilized this structure of supporting disk, when clamping work pieces, only need to make cam prop up supporting disk, take center bolt as axle, on one end that pressing plate is connected with cam, put, and one end of pressing plate holding workpiece is by the bottom, and then holding workpiece, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the height-adjustable clamping device embodiment of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Height-adjustable clamping device as shown in Figure 1, comprise force application structure, pressing plate 4, bearing 5, be arranged on the center bolt 6 on bearing, be arranged on the locking nut 7 of center bolt bottom, be arranged on the adapter sleeve 8 that screw rod is circumferential and be connected with screw flight, be arranged on the E shape snap ring 9 of adapter sleeve outside, the screw 10 that connects pressing plate and adapter sleeve, the supporting disk 11 that is arranged on pressing plate bottom and is threaded with center bolt and the height adjusting nut 12 that is arranged on supporting disk bottom, surface in pressing plate holding workpiece portion is provided with pressure sensor, middle part at described pressing plate has through hole, the internal diameter of described through hole is greater than the external diameter of described adapter sleeve, described pressing plate is arranged in the outside of adapter sleeve by described through hole, between described pressing plate and supporting disk, be provided with back-moving spring, described force application structure comprises the cam 3 that is arranged on pressing plate one end and can offsets with supporting disk, the action bars 2 being connected with cam and cylinder 1 with being connected with action bars by piston rod.
