Abstract
The invention discloses a clamping device with a spiral spring. The clamping device is simple in structure and can automatically reset. The clamping device comprises a clamping platform, a pressing plate is arranged on one side of the clamping platform, one end of the pressing plate is provided with a hooked clamping portion, the middle of the pressing plate is abutted to a compression adjusting screw, the other end of the pressing plate is connected with a force application rod, the compression adjusting screw is connected with a fixing plate, the spiral reset spring is arranged between the fixing plate and the pressing plate, and stoppers are arranged on two sides of the clamping portion of the pressing plate respectively. The pressing plate can stably and automatically reset by the aid of the spiral reset spring.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of with helical spring clamping device.
Background technology
in the processing and manufacturing of workpiece, generally all need clamping device to carry out clamping position to workpiece, and in small batch workpiece manufacture processing, consider Cost Problems, generally adopt the better simply clamping device of structure, and such clamping device often has the following disadvantages: generally adopt cylinder or oil cylinder as power, directly drive jaw to Workpiece clamping, therefore, cannot adopt simple automatic reset structure, operation inconvenience.
Summary of the invention
The invention provides a kind of simple in structure, can realize automatically reset with helical spring clamping device.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
With helical spring clamping device, comprise clamping platform, in clamping platform one side, be provided with pressing plate, described pressing plate one end is hook-shaped clamping part, the middle part of pressing plate with compress adjustment screw offset, the other end of pressing plate is connected with a force application rod, described compression adjustment screw is connected with a fixed head, between described fixed head and pressing plate, be provided with spiral back-moving spring, in the both sides of described pressing plate clamping part, be respectively equipped with block.
The operation principle of this clamping device is as follows: to the force application rod application of force, force application rod is moved downward, and then be with dynamic pressure plate to move downward, the clamping part of pressing plate and the common holding workpiece of clamping platform; In the process moving downward at pressing plate, spiral back-moving spring non-displacement, but described spiral back-moving spring is stretched, therefore, unclamping after force application rod, under the effect of the restoring force of spiral back-moving spring, pressing plate will move upward automatically, return to origin-location, unclamp workpiece.This clamping device compresses adjustment screw by knob and can regulate the thrust of pressing plate.Both sides at pressing plate clamping part arrange block, avoid pressing plate to produce and rock when moving up and down, and guarantee the stability of holding action.
Further, at described pressing plate middle part, be provided with bar shaped chute, described compression adjustment screw end is arranged in described chute.Owing to compressing adjustment screw end, be arranged in chute, therefore, can avoid compressing when adjustment screw props up pressing plate and skid, and cannot play the effect that regulates thrust.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention with helical spring clamping device embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As shown in Figure 1 with helical spring clamping device, comprise clamping platform 1, pressing plate 2, compress adjustment screw 3, fixed head 4, force application rod 5, spiral back-moving spring 6, chute 7, clamping platform upper surface is provided with pressure sensor, pressing plate is arranged on a side of clamping platform, described pressing plate one end is hook-shaped clamping part, the middle part of pressing plate with compress adjustment screw offset, the other end of pressing plate is connected with force application rod, compressing adjustment screw is connected with fixed head, spiral back-moving spring is arranged between fixed head and pressing plate, block is arranged on the both sides of pressing plate clamping part, described chute is bar shaped, chute is arranged on described pressing plate middle part, compressing adjustment screw end is arranged in described chute.
