Abstract
The invention relates to a mechanical processing tool, in particular to a clamping fixture for clamping the inside of a work piece; the internal clamping fixture comprises a frame and a floating block; both sides of the floating block are provided with conical jacking blocks; through holes are arranged in the middle of the floating blocks; guide rods penetrate through the through holes; the guide rods are fixed with the floating blocks; the top ends of the guide rods are hinged with cams; the guide rods are vertically and slidably connected with the frame; both sides of the frame are provided with connecting pieces; the frame is fixedly connected with one ends of the connecting pieces; the other ends of the connecting pieces are hinged with clamping jaws which are matched with the conical jacking blocks to clamp the work piece; pressure springs are arranged below the connecting pieces between the frame and the clamping jaws; and the lower ends of the clamping jaws are movably matched with the conical jacking blocks. According to the internal clamping fixture, the operation is convenient and the work piece is clamped stably.
Description
Technical field
The present invention relates to machine tools, be specifically related to the clamping device of a kind of holding workpiece inside.
Background technology
General 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 usually.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 easy to operate, inside clamping device that holding workpiece 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 frame, rocker piece, the rocker piece both sides are provided with cone-shaped ejecting block, have through hole in the middle of the rocker piece, be equipped with guide rod in the through hole, guide rod and rocker piece are fixed, the guide rod top is hinged with cam, guide rod vertically is slidingly connected to frame, the frame both sides are equipped with connector, and frame is fixedly connected with connector one end, and the connector other end is hinged with the jaw that cooperates holding workpiece with cone-shaped ejecting block, the below that is positioned at connector between frame and the jaw is provided with stage clip, and the jaw lower end is moved with the conical surface of cone-shaped ejecting block and cooperated.
Beneficial effect of the present invention: the cam that the present invention arranges by the rotating guide-bar top is regulated the lifting of guide rod, when cam adjustment rises guide rod, because guide rod and rocker piece are fixed, guide rod will drive rocker piece and rise, cone-shaped ejecting block rises with rocker piece, when cone-shaped ejecting block rises to and contacts with the jaw bottom, because the jaw lower end has with cone-shaped ejecting block and moves the bevel phase that cooperates, the bevel phase that cone-shaped ejecting block will paste the jaw lower end continues to rise, until clamping workpiece.Take connector and jaw hinged place as axle, this moment, clamping was more firm because cone-shaped ejecting block has the inside effect of shoring to the jaw bottom, and jaw top will produce the swing of oblique outward direction, namely workpiece further be applied the chucking power effect.When cam rotates guide rod is descended, cone-shaped ejecting block descends gradually, owing to being provided with stage clip between jaw and the frame, therefore under the outside thrust of stage clip, the jaw lower end will along the cone-shaped ejecting block surface gradually outside pendulum, jaw upper end is with interior pendulum, namely cone-shaped ejecting block and jaw will unclamp workpiece simultaneously.The present invention is simple in structure, easy to operate, clamping stable.
Further, frame inside is positioned at the inner chamber that guide rod has expansion on every side, and this inner chamber is provided with back-moving spring, and back-moving spring lower end and rocker piece are fixed.After back-moving spring is set, unclamp workpiece after, under the pulling force effect of spring, the rocker piece automatic-ascending is resetted.
Further, be provided with handle at described cam.After being set on the cam, handle is more convenient for operating.
Description of drawings
Fig. 1 is embodiment of the invention structural representation.
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 rocker piece 1 and frame 5, rocker piece 1 both sides are provided with cone-shaped ejecting block 2, have through hole in the middle of the rocker piece 1, be equipped with two ends in the through hole and stretch out the guide rod 3 of through hole, guide rod 3 is fixed together with rocker piece 1, guide rod 3 tops are hinged with cam 4, cam 4 is provided with handle 12, guide rod vertically is slidingly connected to frame 5, frame 5 inside are positioned at the inner chamber 10 that guide rod 3 has expansion on every side, be provided with back-moving spring 11 in this inner chamber 10, back-moving spring 11 lower ends and rocker piece 1 are fixing, and frame 5 both sides are equipped with connector 7, frame 5 is fixedly connected with connector 7 one ends, connector 7 other ends are hinged with the jaw 6 that cooperates holding workpiece with cone-shaped ejecting block 2, and the below that is positioned at connector 7 between frame 5 and the jaw 6 is provided with stage clip 8, and jaw 6 lower ends are moved with the conical surface of cone-shaped ejecting block 2 and cooperated, as shown in the figure, workpiece 13 is clamped between cone-shaped ejecting block 2 and the jaw 6.
The course of work of the present invention is as follows: during holding workpiece, cam adjustment rises guide rod, guide rod will drive rocker piece and rise, cone-shaped ejecting block rises with rocker piece, and when cone-shaped ejecting block rose to and contacts with the jaw bottom, the bevel phase that cone-shaped ejecting block will paste the jaw lower end continued to rise, until clamping workpiece, the swing that while jaw top also produces oblique outward direction further applies the chucking power effect to workpiece, blocks workpiece by claw.When unclamping workpiece, the handle rotating cam, guide rod is descended, cone-shaped ejecting block descends gradually, owing to being provided with stage clip between jaw and the frame, therefore under the outside thrust of stage clip, the jaw lower end will be along the cone-shaped ejecting block surface outer pendulum the gradually, the jaw upper end is with interior pendulum, and cone-shaped ejecting block and jaw will unclamp workpiece simultaneously.
