Just, the device for safely installing workpiece, all can be described as fixture.
Fixture is usually by setting element (determining correct position of the workpiece in fixture), clamping device, to knife induction element
(relative position or the guiding tool orientation that determine cutter and workpiece), indexing means (make workpiece that can complete number in once mounting
The processing of a station has circular index device and linear movement two class of indexing means), connecting element and clamp body (fixture bottom
Seat) etc. composition.
Accurate planet internal tooth shell currently on the market, shape are rectangular structures, and this structure is upper special in processing
Time-consuming and laborious, processing cost is quite high.
For above drawback, shell appearance improvement optimization is now carried out, so that process time can shorten
60%, production efficiency is greatly improved, and ensure that product quality.
But existing fixture, it can not be well adapted for improved product, also, existing fixture, list can only be corresponded to
The accurate planet internal tooth shell of one size, when the outer dimension of accurate planet internal tooth shell, after variation, it is necessary to replace another
A fixture, this time just wasted.
Therefore, a kind of adjustable fixture is also needed at present, can clamp various sizes of accurate planet internal tooth shell.
Utility model content
The utility model aiming at the shortcomings in the prior art, provides a kind of for clamping the adjustable folder of internal tooth shell
Tool, structure is simple, ingenious in design, can clamp various sizes of accurate planet internal tooth shell.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: one kind is for clamping
The adjustable fixture of internal tooth shell, including two pieces of symmetrical flexible arc clamping plates, the arc clamping plate is mutual
Mutually close to clamp internal tooth shell, the both ends of every piece of arc clamping plate are connected with movable block；It is set on the outside of the movable block
It is equipped with positioning plate, is provided with spring between the positioning plate and the movable block, positioned at two pieces of the arc clamping plate of the same side
It is connected between positioning plate by connecting shaft, the connecting shaft runs through two pieces of movable blocks, and the spring pocket is set on the connecting shaft, the connecting shaft
Limit baffle ring is symmetrically arranged on upper one section be located between two pieces of movable blocks；The each piece of movable block is rotatably connected to
Connecting rod, the interlinking lever end are connected with gear, and the gear is set in gear-box, and the gear is divided into master gear and from tooth
Rotation is driven by motor in wheel, the master gear, and the gear-box is set to the end of push rod, and the push rod is driven by hydraulic pump and moved
It is dynamic.
Rubber friction disc is provided on the working face of the arc clamping plate.
The utility model structure is simple, ingenious in design, can clamp various sizes of accurate planet internal tooth shell.

Fig. 2 is the utility model Half-edge Structure schematic diagram.
Fig. 3 is existing inner tooth shell body appearance schematic diagram.
Fig. 4 is improved inner tooth shell body appearance schematic diagram.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: such as attached drawing 1 to attached drawing 4
It is shown, it is a kind of for clamping the adjustable fixture of internal tooth shell, including two pieces of symmetrical flexible arc clamping plates
1, the arc clamping plate 1 is adjacent to each other to clamp internal tooth shell, and the both ends of every piece of arc clamping plate 1 are connected with movement
Block 2；It is provided with positioning plate 31 on the outside of the movable block 2, is provided with spring 321 between the positioning plate 31 and the movable block 2,
It is connected between two pieces of positioning plates 31 of the arc clamping plate 1 of the same side by connecting shaft 3, the connecting shaft 3 runs through two pieces of movable blocks
2, the spring 321 is sheathed on the connecting shaft 3, is located at one section between two pieces of movable blocks 2 upper on the connecting shaft 3 symmetrical
It is provided with limit baffle ring 32；The each piece of movable block 2 is rotatably connected to connecting rod 21, and 21 end of connecting rod is connected with gear,
The gear is set in gear-box 4, and the gear is divided into master gear 41 and from gear 42, and the master gear 41 is driven by motor
Rotation, the gear-box 4 are set to the end of push rod 43, and the push rod 43 is driven by hydraulic pump and moved.
Rubber friction disc 11 is provided on the working face of the arc clamping plate 1.
When the present apparatus works, the spacing between two pieces of movable blocks 2 is adjusted, to change the radian of arc clamping plate 1, therefore
The internal tooth shell of various outer diameter size can be clamped.When the spacing between movable block 2 becomes smaller, it will be able to just clamp outer
The internal tooth shell that diameter size becomes smaller；When the spacing between movable block 2 becomes larger, it will be able to which just clamping outer diameter becomes larger
Internal tooth shell.In order to obtain better clamping effect, the present apparatus is additionally provided with rubber friction disc 11, with this rubber friction disc
11 increase the frictional force between internal tooth shell.And rubber friction disc 11 is more soft, will not damage internal tooth shell
Outer surface.
After regulating the spacing between movable block 2, it is necessary to starting clamping work, at this point, starting hydraulic pump is dynamic
Make, it is mobile to make its driving push rod 43, so that two pieces of arc clamping plates 1 be made by warp, to be fitted tightly over internal tooth shell, thus mutually
Complete clamping work.Clamping work is driven using hydraulic pump, is able to maintain self-locking, avoids falling off in clamping process
Contingency.
The present apparatus can automatically adjust the spacing between movable block 2, without being manually adjusted, to save the time
And manpower, and can be avoided worker and contingency occur.
When needing to adjust, start the power supply of motor, so that motor rotates, so that master gear 41 is driven to rotate, it is main
Gear 41 drives again from gear 42 and rotates.After two gear rotations, connecting rod 21 will be made to rotate, and connecting rod 21 just will drive shifting
Motion block 2 is mobile.When movable block 2 is mobile close to positioning plate 31, so that the spacing between movable block 2 becomes larger, therefore arc is clamped
The radius of plate 1 increases, and this makes it possible to the internal tooth shells that just clamping outer diameter becomes larger；It is on the contrary, it will be able to just clamping outer diameter ruler
The very little internal tooth shell to become smaller.
The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh
Subject to sharp claim, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that are each fallen within
The protection scope of the utility model.
The utility model structure is simple, ingenious in design, can clamp various sizes of accurate planet internal tooth shell.
