Abstract
The invention discloses an internal clamping device which comprises a force application device arranged inside a shell body, a force transmission device and a holding device. The force application device is a sliding body of a jacking work piece. A transmission pin and a clamping pin are arranged in the sliding body and are vertical to each other and contacted with each other in an inclined mode. A compression spring is arranged at the bottom of the transmission pin. A reset spring is arranged at the bottom of the sliding body. The work piece is arranged on the sliding body, the sliding body moves downwards under action of self gravity of the work piece, the transmission pin tightly presses the clamping pin under action of the compression spring at the bottom, the clamping pin is jacked out of the clamping work piece, and therefore location through the sliding body and clamping through the clamping pin are achieved.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, be specifically related to a kind of inner clamping device.
Background technology
Clamp again after needing man-hour first to locate accurately workpiece adding, after machining, first unclamp clamping device, then unclamp clamping device.Current clamping device, the location clamps, and adopts distributed clamping mode, and two cover systems are adopted in location and clamping, and such design is comparatively accurate.But when to processing request efficient, complex structure like this, the device that clamping efficiency is low just can not be satisfied the demand.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, can realize location and the inner clamps clamping tool that clamps by a cover actuating system.
For achieving the above object, technical scheme of the present invention is: inner clamping device, comprise the force application apparatus, load transfer device and the clamping device that are arranged in housing, described force application apparatus is the slide mass of jacking workpiece, be provided with trundle and holding pin in described slide mass, described trundle contacts on vertical and inclined-plane mutually with holding pin, and the bottom of described trundle is provided with stage clip, and the bottom of described slide mass is provided with back-moving spring.
When adopting technique scheme, workpiece is placed on slide mass, under the effect of workpiece deadweight, slide mass moves down, and trundle pushes holding pin by the inclined-plane under the effect of bottom stage clip, holding pin is ejected clamping work pieces, thereby realized locating and the clamping of holding pin by slide mass.
Further, for the displacement of limit slippage body and trundle, in order to avoid defective work piece is provided with spacer pin in described housing, be respectively equipped with limit pin hole in described slide mass and trundle.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the inner clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, the inner clamping device of the present invention, comprise the force application apparatus, load transfer device and the clamping device that are arranged in housing 6, described force application apparatus is the slide mass 5 of jacking workpiece 1, be provided with trundle 4 and holding pin 3 in described slide mass 5, described trundle 4 contacts on vertical and inclined-plane mutually with holding pin 3, and the bottom of described trundle is provided with stage clip 11, and the bottom of described slide mass 5 is provided with back-moving spring 12.A spacer pin 9 is arranged in housing 6, be respectively equipped with limit pin hole in slide mass 5 and trundle 4, the displacement of limit slippage body 5 and trundle 4 is in order to avoid defective work piece 1.
Workpiece 1 is placed on slide mass 5, and under the effect of workpiece 1 deadweight, slide mass 5 moves down, trundle 4 is under the effect of bottom stage clip 11, push holding pin 3 by the inclined-plane, holding pin 3 is ejected clamping work pieces 1, thereby realized the clamping by slide mass 5 location and holding pin 3.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from 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.
