Description
Technical Field
The utility model relates to a gear grinding anchor clamps, especially a fluid pressure type gear grinding anchor clamps.
Background
The existing gear grinding clamp is mostly of a mechanical type, a workpiece is tightly propped through an upper tip and a lower tip, a tension device of a machine tool drives a pull rod, the pull rod drives an elastic chuck to move, and a clamp body and the elastic clamp are provided with matched conical surfaces, so that the elastic chuck contracts and clamps the workpiece; but the tension device drives the pull rod to move at a high speed and with large impact, the service life of the elastic chuck is influenced, the lower center is assembled in the body through the mounting hole, precision errors exist, the coaxiality with the upper center is poor, the verticality of a workpiece is influenced, and the processing quality is reduced.
Disclosure of Invention
The utility model aims at the aforesaid that prior art exists is not enough, provides a fluid pressure type gear grinding anchor clamps, and controllable, the little advantage of impact when it has collet to remove can improve its life, and the straightness that hangs down of work piece location is good, can improve processingquality.
In order to achieve the purpose, the utility model discloses a hydraulic gear grinding clamp, which comprises an upper top, a clamp body with a stepped hole arranged therein, a body connected with the clamp body and an elastic chuck; the device is characterized in that a lower tip is fixedly connected with the upper end of the body in an integrated mode, the lower tip is arranged on the upper portion of a stepped hole, the elastic chuck is arranged in the stepped hole outside the lower tip, a matched conical surface is arranged on the outer circle of the front end of the elastic chuck and the front end of the stepped hole, the rear end of the elastic chuck is connected with a piston sleeve in the stepped hole, an extending oil path and a recycling oil path are arranged in the body and communicated with the rear cavity of a piston on the piston sleeve, and the recycling oil path is communicated with the front cavity of the piston on the piston sleeve.
When the elastic chuck is used, after the upper center and the lower center tightly prop against a workpiece, hydraulic oil is introduced through the extending oil way and the recycling oil way, and the piston sleeve drives the elastic chuck to move, clamp or loosen the workpiece;
as a further improvement of the utility model, the side wall of the elastic chuck is provided with an axial guide groove, the chuck body is connected with a screw, and the head of the screw is arranged in the guide groove; the elastic chuck can be prevented from rotating when moving;
as a further improvement of the utility model, the excircle of the piston on the piston sleeve, the excircle of the body behind the rear cavity of the piston and the excircle of the piston sleeve in the front cavity of the piston are all provided with sealing rings; the leakage of hydraulic oil can be prevented, and the normal work of the clamp is ensured;
to sum up, the utility model has the advantages of when collet removes controllable, that strike little, can improve its life, and the straightness that hangs down of work piece location is good, can improve processingquality.
Drawings
Fig. 1 is a front view of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, a hydraulic type gear grinding clamp of this embodiment includes an upper center 1, a clamp body 2 with a stepped hole formed therein, a body 3 connected to the clamp body 2 by a bolt, and an elastic collet 5; the upper end of the body 3 is integrally and fixedly connected with a lower tip 4, the lower tip 4 is arranged at the upper part of a stepped hole, the elastic chuck 5 is arranged in the stepped hole outside the lower tip 4, the excircle of the front end of the elastic chuck 5 and the front end of the stepped hole are provided with matched conical surfaces 6, the rear end of the elastic chuck 5 is connected with a piston sleeve 7 in the stepped hole through threads, the side wall of the elastic chuck 5 is provided with an axial guide groove 11, the clamp body 2 is connected with a screw 12, and the head of the screw 12 is arranged in the guide groove 11; an extended oil path 8 and a recovery oil path 9 are arranged in the body 3, the extended oil path 8 is communicated with a rear cavity of a piston 10 on the piston sleeve 7, and the recovery oil path 9 is communicated with a front cavity of the piston 10 on the piston sleeve 7; and the excircle of the piston 10, the excircle of the body 3 behind the rear piston cavity and the excircle of the piston sleeve 7 in the front piston cavity are respectively provided with a sealing ring 13.
When in use, the upper center 1 is connected with a center seat of a machine tool, and the body 3 is arranged on a workbench of the machine tool; after the upper center 1 and the lower center 4 tightly prop against a workpiece 14, hydraulic oil is introduced through the extending oil way 8 and the recycling oil way 9, the piston sleeve 7 drives the elastic chuck 5 to move and clamp or loosen the workpiece 14, and the moving speed of the elastic chuck 5 is controlled by the pressure of the hydraulic oil, so that the elastic chuck has the advantages of controllability and small impact when moving, the service life of the elastic chuck can be prolonged, the lower center 4 is fixedly connected with the upper end of the body 3 integrally, the coaxiality of the upper center 1 can be improved, the verticality of workpiece positioning is good, and the processing quality can be improved; the screw 12 prevents the collet 5 from rotating when it is moved; each sealing ring 13 can prevent the leakage of hydraulic oil, guarantees the normal work of anchor clamps.
