Abstract
The utility model relates to a machine tool, in particular to a crankshaft lathe which comprises a frame, wherein a headstock is arranged at one end of the frame, a tailstock which can move front and back is arranged at the other end of the upper part of the frame, and a rear headstock is arranged on the tailstock. A lathe floral disc is fixedly arranged on a spindle of the rear headstock, thereby being capable of assisting in clamping work and preventing a workpiece from shaking during rotation. A transmission gear is arranged at the bottom of the rear headstock, and a rack matched with the transmission gear is arranged on a base, the structural design is simple, the tailstock can be controlled to move at any time, and the clamping of the workpiece is facilitated. A shaking handle is arranged on the rear headstock, thereby facilitating the control of the position of the tailstock.
Description
Technical field
The utility model relates to a kind of lathe, specifically is a kind of crankshaft toothed wheel.
Background technology
In existing machine tooling, for the special machining tool of processing needs of big-and-middle-sized bent axle.Because axial workpiece is the rotary body part, its length generally is made up of external cylindrical surface, taper seat, endoporus and screw thread and the corresponding end face of concentric shafts greater than diameter.According to the difference of planform, axial workpiece can be divided into optical axis, multidiameter, hollow shaft and bent axle etc.Their precision and surface quality are generally had relatively high expectations, and its specification requirement is generally formulated according to the main function and the condition of work of axle.Especially the processing of bent axle is the most complicated, and engine lathe is adding man-hour, and the rotary power of main spindle box can not satisfy its processing request, therefore need carry out the corresponding transformation upgrading to it.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and provides a kind of crankshaft toothed wheel, the defective of engine lathe in the time of effectively solving machining crankshafts.
This programme is realized by following technical measures: a kind of crankshaft toothed wheel, comprise support, and support one end is provided with main spindle box, and the upper part of the frame other end is provided with the tailstock that can move forward and backward, and described tailstock is provided with the back main spindle box.
Be fixed with the lathe floral disc on the main shaft of described back main spindle box, can be convenient to clamp workpiece, prevent that workpiece from rocking.
Main spindle box bottom, described back is provided with travelling gear, and pedestal is provided with the tooth bar that matches with travelling gear, and structural design is simple, and can control tailstock at any time and move, and is beneficial to clamping workpiece.
Described back main spindle box is provided with and shakes handle, is convenient to control the tailstock position.
The beneficial effect of this programme can be learnt by the narration of such scheme, because tailstock is provided with the back main spindle box, also can there be power output in the tailstock that is lathe, has brought enough rotary powers for the processing of bent axle, avoids lathe to cause because of being short of power workpiece is caused the processing infringement.Be fixed with the lathe floral disc on the main shaft of described back main spindle box, can assist holding workpiece, prevent that workpiece from rocking when rotated.Main spindle box bottom, described back is provided with travelling gear, and pedestal is provided with the tooth bar that matches with travelling gear, and structural design is simple, and can control tailstock at any time and move, workpiece easy to setup.Described back main spindle box is provided with and shakes handle, is convenient to control the tailstock position.This shows that the utility model compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is main spindle box, and 2 is tool holder, and 3 is the back main spindle box, and 4 is handle, and 5 is gearcase, and 6 is tooth bar, and 7 is support, and 8 is the lathe floral disc.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
Specific embodiment, as shown in Figure 1, a kind of crankshaft toothed wheel comprises support 7, and support 7 one ends are provided with main spindle box 1, and the support 7 top other ends are provided with the tailstock that can move forward and backward, and described tailstock is provided with back main spindle box 3.Be fixed with lathe floral disc 8 on the main shaft of described back main spindle box 3, back main spindle box bottom is provided with gearcase 5, in the gearcase 5 travelling gear is arranged, and support 7 is provided with the tooth bar 6 that matches with travelling gear, and described back main spindle box 3 is provided with and shakes handle 4.
