Utility model content
The purpose of this utility model is, there is provided one effectively can process high strength bulb punch workpiece and machining accuracy is high, structure is simple, make and use cost is lower, Operation and maintenance Cold Extrusion Punch sphere accurate grinding device all easily, to overcome prior art deficiency.
The technical solution of the utility model is achieved in that
A kind of Cold Extrusion Punch sphere accurate grinding device of the present utility model is, this device comprises the support being provided with main shaft, the main shaft of support is rotated by driven by motor, the main shaft of support is provided with the rotary chuck for clamping processed bulb punch workpiece, on support, the below of rotary chuck is fixed with base, base is provided with turntable, turntable is provided with grinding carriage, grinding carriage is provided with the drive lead screw for installing and move horizontally emery wheel, emery wheel is fixed on the front end of drive lead screw, is provided with screw handle at the tail end of drive lead screw.
Above-mentioned turntable is arranged on base by bearing, and turntable can be rotated around bearing axis by electronic or manual mode; Be arranged on the shaft center line of the rotary chuck on support main shaft concentric with the axial line of the drive lead screw on grinding carriage, and the center line of bearing is mutually vertical with the axial line of drive lead screw.
Above-mentioned turntable by electronic or manual mode when bearing axis rotates, its rotating manner be no more than 300 ° carry out back rotation.
The center line of above-mentioned bearing is mutually vertical with the axial line of drive lead screw, and the axial line of the center line of bearing and drive lead screw is parallel and by the same plane of drive lead screw axial line plane.
The processing end face of above-mentioned emery wheel is plane.
Owing to have employed technique scheme, the utility model is rotated under the drive of rotary chuck by bulb punch workpiece and emery wheel is done to carry out back rotation under the drive of turntable and biosynthesis locus is round, simultaneously after emery wheel progressively feeding, on bulb punch workpiece, grinding can go out high-precision bulb sphere like this.Use through actual tests and prove, the bulb punch workpiece of hardness HRc >=55 can be processed the bulb sphere of acceptable precision by the utility model quickly and efficiently, the working (machining) efficiency of the utility model workhardness HRc >=55 bulb punch workpiece is more than 3 times that adopt traditional grinding equipment, and its machining accuracy is much higher than traditional grinding equipment.So compared with prior art, the utility model not only has the advantage effectively processing high strength bulb punch workpiece to the utility model, but also have that machining accuracy is high, structure is simple, make and use cost is low, Operation and maintenance advantage all easily.

Fig. 1 is the structural representation of the utility model device.
Description of reference numerals: 1-bulb punch workpiece, 2-emery wheel, 3-drive lead screw, 4-screw handle, 5-turntable, 6-bearing, 7-base, 8-support, 9-rotary chuck, 10-grinding carriage.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: the structural representation of a kind of Cold Extrusion Punch sphere accurate grinding device of the present utility model as shown in Figure 1, this device comprises the support 8 being provided with main shaft, the main shaft of support 8 can be rotated by driven by motor by belt or gear-driven mode by traditional mode, the main shaft of support is installed one for clamping the rotary chuck 9 of processed bulb punch workpiece 1, this rotary chuck 9 can adopt the chuck structure that traditional lathe or drilling machine use, on support 8, a base 7 is fixed in the below of rotary chuck 9, and on base 7, a turntable 5 is installed, during making, preferably turntable 5 is arranged on base 7 by bearing 6, and turntable 5 can be rotated around bearing 6 center line by electronic or manual mode, bearing 6 preferably adopts angular contact bearing of the prior art, when turntable 5 is made into rotated by electronic mode time, preferably by traditional mode, adopt the driven by motor turntable 5 that can rotate and reverse to carry out back rotation, when turntable 5 being made into manual mode and rotating, directly on turntable 5, a handle is installed, namely makes turntable 5 carry out back rotation by artificial mode, when turntable 5 is rotated around bearing 6 center line by electronic or manual mode, make its rotating manner be no more than 300 ° carry out back rotation, then on turntable 5, a grinding carriage 10 is fixed, and on grinding carriage 10, fill one for installing and move horizontally the drive lead screw 3 of emery wheel 2, emery wheel 2 is fixed on the front end of drive lead screw 3, at the tail end of drive lead screw 3, a screw handle 4 is installed, emery wheel 2 can adopt traditional processing end face to be the emery wheel of plane, greatly can not only reduce making and use cost like this, and can machining accuracy be ensured, during making, the shaft center line of the rotary chuck 9 be arranged on support 8 main shaft should be made concentric with the axial line of the drive lead screw 3 on grinding carriage 10, and make the center line of bearing 6 mutually vertical with the axial line of drive lead screw 3, make the axial line of the center line of bearing 6 and drive lead screw 3 parallel and by the same plane of drive lead screw 3 axial line plane simultaneously.
