Abstract

The invention discloses a machine tool component and specifically relates to a hold-down device capable of returning in position automatically. The hold-down device comprises a worktable, a pressing plate, an adjusting rod and an ejector rod, wherein one end of the adjusting rod is fixedly connected with the worktable, while the other end of the adjusting rod penetrates through a guide hole formed in the pressing plate and is fixedly connected with a cam; a push block propped against the cam is arranged at one end of the pressing plate, while a guide groove is formed at the other end of the pressing plate; one end of the ejector rod is in threaded connection with the worktable, while the other end of the ejector rod is inserted in the guide groove; a compression rod is arranged in the pressing plate, and one end of the compression rod is propped against the adjusting rod, while the other end of the same is propped against one end of a return spring; besides, the return spring causes the end, in contact with a workpiece, of the pressing plate to be far away from the workpiece. The hold-down device is high in efficiency and the pressing plate is capable of returning to the position when not used.

Description

Can automatically reset hold down gag
Technical field
The present invention relates to a kind of machine tool component, be specifically related to a kind of can automatically reset hold down gag.
Background technology
In mechanical processing process, usually need first workpiece to be fixed by clamping device, make workpiece obtain the tram with respect to lathe and cutter, then workpiece is processed.By clamping device, workpiece is fixed, because the positional precision of workpiece is guaranteed by clamping device, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and stable, and then the rate of reducing the number of rejects and seconds, guaranteed the quality of product; Because clamping device can make workpiece location and clamping rapidly, reduce unproductive time significantly again, improved production efficiency.So both can guarantee mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce the excessive demand to workman's technology again.
Because processing needs, some workpiece will fix by hand actuable clamping device conventionally.But some hand actuable clamping devices can only be by screw thread gradually by Workpiece clamping, and efficiency is not high.
Summary of the invention
The technical problem to be solved in the present invention comprises: provide that a kind of service efficiency is high, pressing plate can be got back to the position while not using automatically.
In order to solve the problems of the technologies described above, the invention provides a kind of can automatically reset hold down gag, comprise workbench, pressing plate, adjusting rod and push rod, described adjusting rod one end is fixedly connected with workbench, and the other end passes the pilot hole on pressing plate and is fixedly connected with cam; Described pressing plate one end is provided with the pushing block offseting with cam, and the other end is provided with gathering sill; Push rod one end is threaded with workbench, and the other end inserts in gathering sill; In pressing plate, be provided with depression bar, depression bar one end and adjusting rod offset, and the other end and back-moving spring one end offset; Described back-moving spring makes one end that pressing plate can contact with workpiece away from workpiece.
What adopt such scheme can automatically reset hold down gag, and because back-moving spring makes one end that pressing plate can contact with workpiece away from workpiece, when pushing block is no longer subject to the thrust of cam, pressing plate, by the elastic force of back-moving spring, can be got back to the position while not using.In the next workpiece of clamping, needn't, manually pushing pressing plate aside, increase work efficiency like this.
As preferred version, described cam is fixedly connected with regulating handle.Adopt after such structure, by rotating regulating handle, can rotate by very easy band moving cam, easy to use.
As preferred version, described push rod is provided with adjusting nut.When push rod one end is subject to the pressure of pressing plate, adjusting nut and workbench offset, and prevent thread damage.
As preferred version, one end that described pressing plate contacts with workpiece is provided with rubber antiskid pad.Adopt after such structure, because rubber antiskid is lined with certain elasticity, can prevent that pressing plate from causing damage to surface of the work in the process of fixation workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention can automatically reset hold down gag embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:
In figure, 1 is workpiece, and 2 is pressing plate, and 3 is pushing block, and 4 is cam, and 5 is regulating handle, and 6 is adjusting rod, and 7 is depression bar, and 8 is back-moving spring, and 9 is adjusting nut, and 10 is push rod, and 11 is workbench.
As shown in Figure 1 can automatically reset hold down gag, comprise workbench 11, pressing plate 2, adjusting rod 6 and push rod 10, described adjusting rod 6 one end are fixedly connected with workbench 11, and the other end passes the pilot hole on pressing plate 2 and is fixedly connected with cam 4, and cam 4 is fixedly connected with regulating handle 5.Described pressing plate 2 one end are provided with the pushing block 3 offseting with cam 4, and the other end is provided with gathering sill; One end that pressing plate 2 contacts with workpiece 1 is provided with rubber antiskid pad and pressure sensor.Push rod 10 one end are threaded with workbench 11, and the other end inserts in gathering sill; Push rod 10 is provided with adjusting nut 9, and adjusting nut 9 is between pressing plate 2 and workbench 11.In pressing plate 2, be provided with depression bar 7, depression bar 7 one end and adjusting rod 6 offset, and the other end and back-moving spring 8 one end offset; Described back-moving spring 8 makes one end that pressing plate 2 can contact with workpiece 1 away from workpiece 1.
During use, after workpiece 1 is placed on workbench 11, by stirring regulating handle 5, make cam 4 rotations, and then compressing pushing block 3 makes its band dynamic pressure plate 2 approach workpiece 1 and finally make rubber antiskid pad be against workpiece 1 surface.After workpiece 1 machines, stir regulating handle 5 in the other direction, pushing block 3 is no longer subject to the thrust of cam 4, and pressing plate 2 is by the elastic force of back-moving spring 8, can get back to the position while not using, after the workpiece processing 1 is taken off, can carry out clamping to next part workpiece 1 immediately and fix.
By rotation push rod 10, regulate push rod 10 length between pressing plate 2 and workbench 11, can change the suffered thrust of workpiece 1.When the suffered thrust of workpiece 1 is excessive or when too small, can make pressure sensor start alarm device, prompting staff changes the suffered thrust of workpiece 1.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
