Abstract
A main shaft driving centre of a new energy motor shaft is integrally formed with a centre driving part when the new energy motor shaft is processed by a numerical control lathe, and a connecting end of a centre positioning part is embedded in a groove at the front end of the centre driving part and used for positioning a central hole of a workpiece. The centre connecting portion adopt morse taper shank structure for with lathe main shaft taper hole cooperation installation, it has involute outer spline structure to open on the top drive division for with the cooperation of work piece internal spline, stability is good, the machining precision improves, need not frequently to carry out the frock moreover and repaiies. The tip positioning part is made of hard alloy, so that the tip positioning part is wear-resistant and long in service life. The center connecting part, the center driving part and the center positioning part are connected into a whole, so that the center driving device is simple to manufacture, low in processing cost and suitable for all standard numerically controlled lathes.
Description
Technical Field
The utility model relates to a main shaft driving center for a new energy motor shaft during machining of a numerical control lathe.
Background
At present, a new energy motor shaft is usually machined in a one-clamping one-top mode during numerical control precision machining, namely a spindle end is clamped by a three-jaw chuck, a tailstock is machined in a top mode, in order to guarantee turning form and location tolerance accuracy during machining, manual centering is usually required to be conducted after a workpiece is clamped, machining efficiency is low, and the motor shaft is not suitable for batch production. SUMMERY OF THE UTILITY MODEL
Disclosure of Invention
The utility model aims to solve the existing problems and provide the spindle driving center with high clamping efficiency, simple operation and suitability for batch production.
The utility model is realized by the following steps: the center connecting part is of a Morse taper shank structure and is used for being installed in cooperation with a taper hole of a lathe spindle, the center driving part is adjacent to the center connecting part, an involute external spline is arranged on the center driving part and is used for being matched with an internal spline of a workpiece to drive the workpiece to rotate, and the center positioning part is embedded in a groove in the front end of the center driving part and is used for positioning a center hole of the workpiece.
The center positioning device has the advantages that the center connecting part and the center driving part are integrated, and the connecting end of the center positioning part is embedded in the groove at the front end of the center driving part and is used for positioning the center hole of the workpiece. The top connecting portion adopt morse taper shank structure for with lathe spindle taper hole cooperation installation, it has involute external spline structure to open on the top drive division for with the cooperation of work piece internal spline, stability is good, the machining precision improves, need not frequently to carry out the frock moreover and repaiies. The tip positioning part is made of hard alloy, so that the tip positioning part is wear-resistant and long in service life. The center connecting part, the center driving part and the center positioning part are connected into a whole, so that the center driving mechanism is simple to manufacture, low in processing cost and suitable for all standard numerically controlled lathes.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view of fig. 1.
Detailed Description
The utility model is described in detail below with reference to the accompanying drawings: as shown in the figure, the center positioning device is formed by integrating a center connecting part 1, a center driving part 2 and a center positioning part 3, wherein the center connecting part 1 and the center driving part 2 are integrally processed, a groove is formed in the end face of the center driving part 2, and the center positioning part 3 is embedded into the groove of the center driving part 2. The center driving part 2 is of a Morse taper shank structure and is used for being matched and fixedly installed with a taper hole of a lathe spindle, an involute outer spline structure is arranged on the center driving part 2 and is used for being matched with an inner spline of a workpiece, and the center positioning part 3 is machined by hard alloy and is used for being matched and positioned with a center hole of the shaft end of the workpiece. When the lathe spindle rotates, the driving center connecting part 1, the driving center driving part 2 and the center positioning part 3 are driven to rotate together, and the external spline of the driving center driving part 2 is matched with the internal spline of the workpiece, so that the workpiece synchronously rotates under the driving of the driving center driving part 2, and the turning processing is carried out.
