Abstract

The invention discloses an internal clamping fixture which comprises a force applying rod; the upper end of the force applying rod is provided with a flange; clamping jaws and a support are arranged in the side direction of the force applying rod; the middle parts of the clamping jaws are connected onto the support through rotating shafts, the lower ends of the clamping jaws are provided with return blocks capable of clamping the flange of the force applying rod, and the inner sides of the clamping jaws are provided with oblique surface sections; the oblique surface section is contacted with the flange shape of the force applying rod; and the upper parts of the clamping jaws are provided with compression blocks capable of clamping a work piece. According to the internal clamping fixture, the structure is simple, the operation is convenient and the clamping is stable.

Description

Inner clamping device
Technical field
The present invention relates to tool for mechanical machining, be specifically related to a kind of inner clamping device.
Background technology
Usually anchor clamps are to fix workpiece by the holding workpiece outside; make it to occupy correct position; but the holding workpiece outside tends to cause cut to surface of the work; affect the crudy of workpiece; therefore for the workpiece of some exterior light slipperies that need protection, holding workpiece inside is come workpiece is fixed.And at present, the anchor clamps of holding workpiece inside often exist complex structure, operation inconvenience, and the unsettled defective of clamping, affect the crudy of workpiece.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, easy to operate, inside clamping device that clamping is stable.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of inner clamping device, comprise force application rod, the force application rod upper end has flange, force application rod is laterally disposed jaw and support, the middle part of jaw is connected on the support by rotating shaft, and the jaw lower end is provided with the piece of returning that can block the force application rod flange, and the inboard of jaw is bevel phase, bevel phase contacts with the force application rod flange-shape, and the top of jaw is provided with the compact heap that can block workpiece.
Take the bevel phase of jaw inboard as downward-sloping from top to bottom bevel phase as example, when force application rod flange of the present invention props up jaw bevel phase upper end, clamping work pieces, force application rod is moved downward in the process of jaw bevel phase lower end by jaw bevel phase upper end, and the clamping principle is as follows:
Force application rod moves downward, because a section of contact with the force application rod flange in the inboard of jaw is downward-sloping bevel phase, so when the flange of force application rod moved downward above the rotating shaft in the middle part of jaw, the compact heap on jaw top unclamped workpiece with interior pendulum; The force application rod flange continues to move downward through the rotating shaft of jaw middle part, and the jaw lower end is interior pendulum, and take rotating shaft as axle, the compact heap on jaw top is outer pendulum, and workpiece pressing again, force application rod stop to move downward until move to and return piece and block till its flange; Force application rod moves upward, when the force application rod flange moves below the jaw rotating shaft, the jaw lower end is outer pendulum gradually, take rotating shaft as axle, jaw top is interior pendulum gradually, unclamps workpiece, and rotating shaft continues in the process of moving upward the force application rod flange through jaw, to the compact heap of jaw upper end be put outward, again clamping work pieces.
To sum up, the present invention just can realize the two times of clamping of workpiece and unclamp action by once up and down motion of force application rod, greatly facilitates staff's operation, improves clamping efficient, and the present invention is simple in structure, clamping is stable.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Inside clamping device as shown in Figure 1, comprise force application rod 1, force application rod 1 upper end has flange 11, force application rod 1 is laterally disposed jaw 2 and support 3, the middle part of jaw 2 is connected on the support 3 by rotating shaft 23, jaw 2 lower ends be provided with can block force application rod 1 flange 11 return piece 21, jaw 2 inboards are bevel phase 24, one section of contacting with force application rod 1 flange 11 in the inboard of jaw 2 is outward-dipping from top to bottom bevel phase, bevel phase 24 contacts with force application rod 1 flange 11 shapes, and the top of jaw 2 is provided with the compact heap 22 that can block workpiece 4.
The present invention just can realize the two times of clamping of workpiece and unclamp action by once up and down motion of force application rod, greatly facilitates staff's operation, improves clamping efficient, and the present invention is simple in structure, clamping is stable.
