Description
Technical field
The present invention relates to digit ctrol machine tool field more particularly to a kind of parallel multi-channel numerically-controlled machine tools.
Background technique
In the prior art, using smart phone as the 3C Product parts machining of representative, single is of large quantities, machining allowance is few,
Update cycle is short, generallys use that traditional brill attacks center, vertical machining centre is processed at present, and processing efficiency is low, and lathe accounts for
Ground area is big, and a machine tool needs an operator.
Patent document CN202640067U (day for announcing is on January 2nd, 2013) discloses a kind of multi-axis NC Machine Tools, passes through
Multiple Z axis and processing head main shaft are set on same X slide plate, so as to form multiple processing stations, realize high efficiency processing.But its
Each machining spindle can not independently carry out position adjustment, can not achieve the tool compensation function of the single processing head of numerical control processing.
It is also difficult to realize the setting on-line measurement device near processing head, such as contact type probe, industrial vision ccd sensor, swash
Optical measuring instrument etc., to carry out additional work after secondary fine tuning is repaired to mismachining tolerance.In addition, fixed Z axis is set with processing head main shaft
It sets, it is difficult to the correspondence of adaptable fixture installation site and processing head position, to adjust the location error that workpiece is packed into fixture.
Patent document CN101472707A (publication date is on July 1st, 2009) discloses one kind can in operation again
Position the main axle unit of working-spindle.Its by main shaft be arranged can in the device that tri- directions X, Y, Z are accurately adjusted,
More main-shaft core coordinates and its axial position can be adjusted in real time, be allowed to on same workbench fixture exactitude position and adapt to not
With the cutter of length, it is ensured that compared with high manufacturing accuracy.This adjustment device, so that the construction of main axle unit and control are sufficiently complex.
Addition work after the cutter compensation of numerical control processing, on-line measurement is also not easily accomplished.
Patent document CN106739727A (publication date is on May 31st, 2017), CN107825226A (publication date 2018
On March 23) individually disclose a kind of binary channels, multichannel individually controls carving machine, both by being set on lathe bed respectively
Multiple independent Y-direction workbench are set, multiple independent X slide units, Z slide unit and processing head are set on crossbeam, are constituted independent more
The multichannel lathe in Numeric Control Technology is realized so as to form multiple independent processing channels on the same lathe bed in channel, and with
This improves processing efficiency, reduces space hold, improves machining accuracy.
Machine tool structure disclosed in especially patent document CN107825226A, be arranged on crossbeam multiple independent X slide plates,
Z sled mechanism, including the first, second, third sled mechanism, sled mechanism is respectively by the different location that is mounted in crossbeam slot
Ball screw and servo motor mechanism driving, these servo motor driving mechanisms in different manners staggered arrangement in crossbeam slot
It is interior, so that assembly, maintenance are very inconvenient, such as assembly maintenance is carried out to screw rod bearing, the shaft coupling of servo motor driving mechanism
When, need corresponding slide plate to carry out position evacuation.When if necessary to be laid out more slide plates, multiple movable slide plates can be to its bottom
Servo motor driving ball wire rod mechanism generate masking.
In addition, the lubrication management of servo motor and its sensor cable and ball screw, straight-line guide rail slide block interferes with each other,
So that it is very untidy in crossbeam slot, it is unfavorable for design layout and assembly maintenance.
Further, it for bull or multichannel lathe, requires consideration for how to be arranged more in limited dimensional space
More processing heads and processing channel, because the quantity of processing head determines that the quantity of processing channel setting, processing channel quantity are determined
Determined processing efficiency, and the quantity of processing head by the center between processing head away from determining, therefore, it is necessary to reasonably design to reduce
The center of processing head away from, but lesser processing head center away from meeting so that the space between X slide plate is more compact, to generate more tight
The position masking of weight.

The difference of present embodiment and first embodiment essentially consists in motor driven in ball lead screw drive mechanism 2
The structure of mechanism, the following detailed description of.
As sayed in first embodiment, if the first left cross slide 41 is set to the left side of the second left cross slide 43,
So second left cross slide 43 will simply fail to the first left transverse direction to roll left when being located at left end on ballscrew 2213 second
The area operation that slide plate 41 covers." second rolls left ballscrew 2213 when being located at left end it is appreciated that described herein
The region that first left cross slide 41 is covered " is the idle region that can not be run for the second left cross slide 43.Therefore, exist
In present embodiment, the second left motor-driven mechanism is set to a left side for crossbeam slot 111 with the first left motor-driven mechanism dislocation
At end position, and the second left motor-driven mechanism is more kept right setting.It is appreciated that the second left motor-driven mechanism is relative to first
Left motor-driven mechanism is more kept right, and second, which rolls left, is covered by the first left cross slide 41 when being located at left end on ballscrew 2213
Region firmly is with regard to smaller, that is, the range in idle region is with regard to smaller.Therefore, the second left motor-driven mechanism is relative to the first left electricity
Machine driving mechanism, which keeps right to shift to install, can reduce or eliminate the second idle region for rolling left ballscrew left end.Similarly, first is right
Motor-driven mechanism is set at the right end position of crossbeam slot 111 with the second right motor-driven mechanism dislocation, and the first right electricity
Machine driving mechanism more keeps left setting.Similarly, the idle region of the first right ball screw right end can be reduced or eliminated.
Preferably, the distance between the right side of the second left motor-driven mechanism and the transverse center position of crossbeam 1 be not small
The right side of the first left cross slide 41 when being located at left end and the distance between the transverse center position of crossbeam 1.In this way,
It can avoid influencing the impulse stroke of the second left cross slide 43 while reducing or eliminating above-mentioned " idle region ".Together
Reason, the distance between left side and the transverse center position of crossbeam 1 of the first right motor-driven mechanism, which are not less than, is located at right end
When the second right cross slide 44 left side and crossbeam 1 the distance between transverse center position.In such manner, it is possible to reduce or
Avoid influencing the impulse stroke of the first right cross slide 42 while eliminating above-mentioned " idle region ".
Preferably, in the present embodiment, the cross between the second left motor-driven mechanism and the first left motor-driven mechanism
It is configured so that the first left cross slide 41 when being located at right end does not cover the second left motor-driven mechanism to dislocation length, together
Reason, the transversion malposition length between the first right motor-driven mechanism and the second right motor-driven mechanism should be configured so as to be located at
The second right cross slide 44 when left end does not cover the first right motor-driven mechanism.In such manner, it is possible to avoid driving to motor as far as possible
Assembly, the maintenance of motivation structure are made troubles.
By using above-mentioned technical proposal, the layout of ball lead screw drive mechanism is more reasonable, can not influence each cunning
In the case where the impulse stroke of plate, reasonably reduce the first right ball screw and second roll left ballscrew length, and then reduce
The manufacturing cost of ball screw, at the same can increase the first right ball screw and second roll left ballscrew stable transmission
Property.
