The utility model discloses processing sector gear makes, and the machining precision is higher, and it is more convenient that the clamping is rectified and processing, effectively improves machining efficiency.
Description
Technical Field
The utility model relates to a sector gear is appurtenance's for finish turning technical field, concretely relates to sector gear finish turning frock.
Background
At present, in the field of machining, particularly gear machining, when sector parts are subjected to finish turning and other machining, the sector parts to be machined need to be fixed on a machine tool, clamps on the machine tool are all universal clamps, only workpieces can be fixed, the positions of the workpieces cannot be guaranteed, the positions of the sector parts are very difficult to align and adjust, and in actual machining, the center of gravity is not at the center of gravity of rotation, so that vibration is easily caused, and the precision and the roughness of the workpieces are reduced.
In the traditional method, the central position of the workpiece must be manually corrected according to the standards such as an inner hole, and the positions of the four claws are adjusted one by one to ensure that the workpiece is at the correct position.
However, whether the rotational speed is manually adjusted or reduced; the problems of clamping and gravity center cannot be thoroughly solved; the manual adjustment has larger error, and the condition that the vertical stroke of the clamp exceeds is often generated according to the specification of a workpiece; in addition, machining errors caused by eccentricity cannot be completely eliminated; therefore, the traditional processing method has unsatisfactory efficiency, processing precision and processing simplicity.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model provides a sector gear finish turning frock, its technical problem that solve how to improve clamping and the machining precision to sector gear, improve machining efficiency.
For solving the technical problem, the utility model provides a following technical scheme:
sector gear finish turning frock, including the ring flange, the locating pin is installed at the center of ring flange, the ring flange is in the dog and the balancing piece of arcuation are installed to locating pin one side detachably, still install a plurality of mobilizable clamp plates that are used for compressing tightly sector gear on the ring flange.
The positioning pin is in threaded connection with the inner hole of the flange plate, one end of the positioning pin protrudes out of the working surface of the flange plate, and a gap is reserved between the positioning pin and the stop block.
The stop block and the balance blocks are concentrically arranged, and the stop block and the balance blocks are in threaded connection with the flange plate.
The flange plate is provided with a connecting hole, the pressing plate is provided with a waist-shaped hole corresponding to the connecting hole, and the pressing plate is connected to the flange plate through a fastening screw.
Compared with the prior art, the utility model beneficial effect who has is: the workpiece is not required to be manually adjusted in the clamping process before machining and the actual machining process of the workpiece, the position of the workpiece can be ensured only by simple fitting and installation, the machining of the sector parts is simplified into the machining of common disc parts due to the complex shape, the machining difficulty that the center of gravity is not at the rotation center in the machining of the sector parts is solved through the balance weight, the precision and the qualification rate of gear machining are improved, more importantly, the workpiece clamping efficiency is greatly improved, and the operation complexity is remarkably reduced.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a schematic view of the present invention;
fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
As shown in the figure, this kind of sector gear finish turning frock in this embodiment, including ring flange 1, locating pin 2 is installed at the center of ring flange 1, and the effect of locating pin 2 is the commentaries on classics hole of location sector gear 7, ring flange 1 is in 2 one side detachably of locating pin installs the dog 3 and the balancing piece 4 of arcuation, and the effect of dog 3 is used for pasting tight sector gear 7 and further fixes a position it, and the unstable phenomenon of the focus that sector gear produced after ring flange 1 is installed to the effect of balancing piece 4 is overcome to the weight through balancing piece 4, guarantees that the focus is at centre of gyration when actually processing, still install a plurality of mobilizable clamp plates 5 that are used for compressing tightly sector gear 7 on ring flange 1.
In this embodiment, the positioning pin 2 is screwed into the inner hole of the flange 1, and one end of the positioning pin protrudes out of the working surface of the flange 1 and has a gap with the stopper 3.
In this embodiment, in order to achieve a better balancing effect, the stopper 3 and the balance weight 4 are concentrically arranged, and both the stopper 3 and the balance weight 4 are screwed on the flange plate 1.
In order to enable the pressure plate to effectively press the sector gear 7 and to be able to perform a position adjustment for sector gears 7 of different sizes, the pressure plate 5 is arranged to be movable: the flange plate 1 is provided with a connecting hole, the pressing plate 5 is provided with a waist-shaped hole 51 corresponding to the connecting hole, and the pressing plate 5 is connected to the flange plate 1 through a fastening screw 6.
When the device is used, the stop block 3 and the balance block 4 are connected to the flange plate 1 in a threaded mode, then a workpiece is attached to the working surface of the flange plate 1, the rotary hole of the workpiece is inserted into the positioning pin 2, and meanwhile the small arc surface of the workpiece is enabled to be attached to the inner arc surface of the stop block 3; then, installing a pressing plate, and enabling the pressing plate 5 to tightly press the side face of the workpiece and fix the workpiece; and finally, clamping the flange plate 1 by using a lathe chuck, finishing clamping after correcting the inner hole of the workpiece and the plane reference, and starting turning.
