Detailed Description

The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 4.

A single-hanging waterwheel.

As shown in fig. 1, six sets of processing devices are mounted on the outer periphery of a bed 1, so that workpieces can be processed in different modes, a machine tool spindle 4 is horizontally arranged in the bed 1, a turntable 7 is mounted at one end of the machine tool spindle 4, six clamp assemblies 8 for fixing the workpieces are arranged on the outer periphery of the turntable 7, the workpieces are fixed on the clamp assemblies 8 and then processed, and the workpieces can be switched to another station through rotation of the machine tool spindle 4 so as to be processed in the next step, wherein the specific structures and principles of the processing devices and the clamp assemblies 8 are prior art, and therefore, the detailed explanation is omitted herein.

With reference to fig. 2 and 4, a machine tool spindle 4 is horizontally arranged in the supporting portion 3, the rear end of the machine tool spindle 4 is rotatably arranged in the supporting portion 3, the front end of the machine tool spindle 4 extends out of the supporting portion 3 and is suspended in the machine tool body 1, a spindle mounting hole 2 is formed in one side of the machine tool body 1, the supporting portion 3 extends from the inner side of the spindle mounting hole 2, the extending supporting portion 3 can increase the bearing area of the spindle, and therefore local bearing force is reduced, and the machine tool spindle 4 can be stably mounted on the spindle mounting hole 2 on one side.

This kind of mounting means of lathe main shaft 4, when the lathe main shaft 4 broke down, need not to pull down whole main shaft, because the front end is unsettled, so as only need from the part of front end overhaul can for dismouting easy maintenance.

Referring specifically to fig. 2, a first bearing 5 is disposed between the inlet end of the support portion 3 and the machine tool spindle 4, and a second bearing 6 is disposed between the outlet end of the support portion 3 and the machine tool spindle 4.

This technical scheme is through the bearing that both ends set up around, thereby the whole anterior bearing support of main shaft has been realized, the mode that the unsettled setting in rear portion, because machine tool main shaft 4 only has one end to be fixed in lathe bed 1, and the other end is unsettled in lathe bed 1, therefore this one end that machine tool main shaft 4 is fixed can bear great power, consequently, entrance point and exit end department through at supporting part 3 set up two bearings, make machine tool main shaft 4 receive power and can be evenly spread out both ends, the unsettled and too big problem of other end atress that leads to of main shaft one end has been solved, can guarantee the stability of operation, be convenient for maintain simultaneously.

Preferably, the first bearing 5 is a deep groove ball bearing, and the deep groove ball bearing mainly bears radial load and can bear radial load and axial load simultaneously. When it is subjected to only radial loads, the contact angle is zero. When the deep groove ball bearing has larger radial play, the deep groove ball bearing has the performance of an angular contact bearing, can bear larger axial load, has small friction coefficient and high limit rotating speed; the second bearing 6 is a crossed roller bearing, the rollers are vertically and crossly arranged at 90 degrees in the internal structure of the crossed roller bearing, and the rollers are provided with spacing retainers or spacing blocks, so that the rollers can be prevented from being mutually abraded due to the inclination of the rollers, and the increase of the rotating torque is effectively prevented. In addition, one side of the roller does not contact or lock; the non-standard crossed roller bearing has the advantages that the gap can be adjusted because the inner ring and the outer ring are of the split structure, high-precision rotary motion can be obtained even if pre-compression is applied, operation and installation are simplified, larger axial and radial loads can be borne, and installation space is greatly saved.

Specifically, referring to fig. 2, an oil inlet pipe mounting hole 9 is formed in the other side of the lathe bed 1, a support fixing sleeve 10 is mounted in the oil inlet pipe mounting hole 9, the support fixing sleeve 10 is communicated with an accommodating cavity 11 of the turntable 7, the accommodating cavity 11 is formed in the turntable 7, an oil pressure diverter valve 12 for supplying oil pressure to the clamp assembly 8 is arranged in the accommodating cavity 11, the oil pressure diverter valve 12 is connected with a hydraulic station through an oil pipe 13, the oil pipe 13 is arranged in the support fixing sleeve 10, the oil pipe 13 is protected, the service life is prolonged, and oil in the oil pipe 13 can be effectively prevented from leaking into the lathe bed; the function of the flow dividing valve is to supply the same flow rate (equal flow dividing) to more than two actuators from the same oil source in the hydraulic system, or supply the flow rate (proportional flow dividing) to two actuators according to a certain proportion, so as to keep the speeds of the two actuators in a synchronous or proportional relationship.

Specifically, referring to fig. 2, a left cover plate 17 is mounted on the left end face of the turntable 7, and an O-ring 18 is disposed between the left cover plate 17 and the end face of the support portion 3, so as to further ensure the sealing performance between the left cover plate and the support portion, and improve the use performance of the device.

Referring to fig. 3 in particular, a framework oil seal 14 is arranged between the support fixing sleeve 10 and the turntable 7, so that the sealing performance of the joint between the support fixing sleeve 10 and the turntable 7 is improved, and external chips and cutting fluid are prevented from entering the turntable 7.

With reference to fig. 2 and 3, a left connecting member 15 is sleeved at the left end of the machine tool spindle 4, and the first bearing 5 is arranged between the left connecting member 15 and the support portion 3; the right-hand member cover of lathe main shaft 4 is equipped with right connecting piece 16, is provided with between right connecting piece 16 and the supporting part 3 second bearing 6 through the design of left connecting piece 15 and right connecting piece 16, owing to increased the weight of lathe main shaft 4, simultaneously can be better carry out the adaptation with the bearing, consequently holistic structure is more firm.
