Abstract
The invention discloses a spring automatic clamping device to solve the problem that an existing clamping device easily causes damage to the surface of a workpiece. The spring automatic clamping device comprises a clamping platform. Pressing plates are hinged to the two opposite sides, located on the platform surface, of the clamping platform respectively, a clamping ring is arranged on the side, located on the platform surface of the clamping platform, of each pressing plate, tensioning springs are arranged on the two sides of the platform surface of the clamping platform respectively, a hook which can be clamped with the corresponding clamping ring is arranged at the end of each tensioning spring, a threaded hole is formed in the portion, between the two pressing plates, of the clamping platform, a stand column is connected to the threaded hole in a threaded mode, and the upper portion of the stand column is provided with a flange which can be used in cooperation with the pressing plates for clamping the workpiece. By means of the spring automatic clamping device, impact on the surface of the workpiece in the clamping process can be reduced, and damage to the workpiece can be avoided.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of spring automatic clamping device.
Background technology
fixture is widely used in the manufacture processing of workpiece, and considers the demand of the processing and manufacturing cost that as far as possible reduces workpiece, and General Requirements clamp structure is simple, convenient operation.At present, often there is following problem in the fixture of general shaft-like workpiece: by cylinder or oil cylinder direct tape splicing dynamic pressure plate holding workpiece, often there is the unsettled problem of transmission in such kind of drive, larger to workpiece impulse force dynamics while clamping, the workpiece that effects on surface smoothness etc. has higher requirements can cause damage simultaneously.
Summary of the invention
The invention provides a kind of spring automatic clamping device, to solve existing clamping device, easily surface of the work is caused the problem of damage.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Spring automatic clamping device, comprise grain-clamping table, the relative both sides that grain-clamping table is positioned on table top are hinged with respectively pressing plate, a side that is positioned at grain-clamping table table top on pressing plate is provided with snap ring, the both sides of grain-clamping table table top are respectively equipped with extension spring, and the end of each extension spring is equipped with the grab that can engage with snap ring, on grain-clamping table, between two pressing plates, is provided with screwed hole, the column that has been threaded on screwed hole, the top of described column is provided with the flange that coordinates holding workpiece with pressing plate.
This fixture operation principle: not during holding workpiece, two pressing plates are in free open configuration, workpiece is placed on grain-clamping table, one side of workpiece is clamped by flange, pulls pressing plate, until pressing plate side props up the opposite side of workpiece, now the grab of extension spring end is engaged with the snap ring on pressing plate, because extension spring is in extended state, so the power that extension spring is replied will make pressing plate workpiece pressing, clamping position; While unclamping workpiece, only separately grab and snap ring can unclamp workpiece smoothly.As from the foregoing, this fixture before this pressing plate contacts with workpiece, and then clamps by the restoring force band dynamic pressure plate of spring, compares with existing fixture, can greatly reduce the impact to surface of the work.
Further, at described pressing plate, away from the end of grain-clamping table, be provided with the locating piece of workpiece.Locating piece rotates in the time of can preventing piece-holder, affects machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of spring automatic clamping device embodiment of the present invention;
Fig. 2 is clamping device schematic diagram during holding workpiece not in Fig. 1 embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As Fig. 1, spring automatic clamping device shown in Fig. 2, comprise grain-clamping table 1, the relative both sides that grain-clamping table 1 is positioned on table top are hinged with respectively pressing plate 2, a side that is positioned at grain-clamping table 1 table top on pressing plate 2 is provided with snap ring 3, pressing plate 2 is provided with the locating piece 4 of workpiece away from the end of grain-clamping table 1, the both sides of grain-clamping table 1 table top are respectively equipped with extension spring 5, the end of each extension spring 5 is equipped with the grab 6 that can engage with snap ring 3, on grain-clamping table 1, between two pressing plates, be provided with screwed hole, column 7 has been threaded on screwed hole, the top of column 7 is provided with the flange 8 that coordinates holding workpiece with pressing plate 2, on the clamping face of described grain-clamping table table top and pressing plate, be equipped with pressure sensor.
Claims (2)
1. spring automatic clamping device, it is characterized in that, comprise grain-clamping table, the relative both sides that grain-clamping table is positioned on table top are hinged with respectively pressing plate, and a side that is positioned at grain-clamping table table top on pressing plate is provided with snap ring, and the both sides of grain-clamping table table top are respectively equipped with extension spring, the end of each extension spring is equipped with the grab that can engage with snap ring, on grain-clamping table, between two pressing plates, be provided with screwed hole, the column that has been threaded on screwed hole, the top of described column is provided with the flange that coordinates holding workpiece with pressing plate.
2. spring automatic clamping device according to claim 1, is characterized in that, is provided with the locating piece of workpiece at described pressing plate away from the end of grain-clamping table.
