Abstract
The utility model discloses a horizontal numerically-controlled lathe used for machining an ultra-long large-diameter shaft. The horizontal numerically-controlled lathe comprises a main shaft box, a feeding mechanism, maneuvering boxes, a tail block and a lathe bed. The main shaft box is fixed at one end of the lathe bed and connected with a clamping plate. The feeding mechanism is located at one side of the main shaft box and comprises a motor A and a screw rod, wherein the motor A and the screw rod are connected with each other. The screw rod moves along a guide rail which is a linear slide rail. A ball-type guide rail block is installed on the linear slide rail. The tail block is fixed at the other end of the lathe bed and slides in the X-axis direction. A tip is arranged on the tail block. A knife rest is installed on a middle dragging plate through a guide rail pair and drives the transverse screw rod to move along the guide rail pair through a motor B. One maneuvering box is arranged on one side of the guide rail pair. Another maneuvering box, a scrap removing groove and a cooling device are installed on the lathe bed. The horizontal numerically-controlled lathe is strong in product bearing capacity, stable in operation, and capable of ensuring machining accuracy of the ultra-long large-diameter shaft.
Description
Technical field
The utility model relates to a kind of lathe, specifically a kind of overlength major diameter axle class processing special horizontal numerically controlled lathe.
Background technology
The rigidity of overlength major diameter axle is relatively poor, and when it was carried out digital control processing, if clamping is improper or the rigidity of support component is not enough, then the effect because of cutting force and gravity occured bending and deformation, thus precision and the surface quality of the processing of influence axle.Especially for the multidiameter of overlength, the inconsistent phenomenon of different diameter of axle mismachining tolerances can occur, especially the scale error of small axle diameter part is bigger, and diameter of axle gradient is more big, and then the inconsistent problem of mismachining tolerance is more outstanding.In addition, the feed time of a stroke of overlength multidiameter Vehicle Processing is long, and the deviation accumulation that each ladder produces gets up to influence the degree of accuracy of product geometry.
What existing numerically controlled lathe generally adopted is hard rail, but the friction of hard rail is big, and the row that goes out to lie prone easily increases the weight of motor load, difference in response, is used for processing super long major diameter axle and can not obtains surface of good roughness and precision, does not reach processing request.
The utility model content
The technical problems to be solved in the utility model provides a kind of weight capacity numerically controlled lathe strong, stable, processing super long major diameter axle.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Overlength major diameter axle processing special horizontal numerically controlled lathe comprises main spindle box, feed mechanism, operation panel, dead head and lathe bed, and described main spindle box is fixed in an end of lathe bed, and main spindle box is connected with chuck; Feed mechanism is positioned at a side of main spindle box, comprises interconnective motor A and screw mandrel, and described leading screw is along guide rail movement, and described guide rail is linear slide rail, and the ball bearing type curtain rail piece is installed on the linear slide rail; Dead head is fixed in the other end of lathe bed and can slides along X-direction, be equipped with top on the dead head, described knife rest is installed on the middle carriage by guideway, and knife rest drives cross lead screw by motor B and moves along guideway, and a side of guideway is provided with operation panel; Operation panel, chip area and cooling device also are installed on the described lathe bed.
Described guide rail surface hardness is greater than HRC58, and the thickness of hardened layer is 1-2mm.
The datum clamp face of described ball bearing type curtain rail piece and the depth of parallelism between guide rail surface are less than 0.02mm/1000mm.
Compared with prior art, useful technique effect of the present utility model has:
Linear slide rail is that steel ball is done infinite scroll circulation between slide rail, load platform along slide rail easily high accuracy move linearly.Therefore guide rail can be realized the straight-line guidance effect of overweight load, ultrahigh rigidity function; And guide rail surface hardness is greater than HRC58, the thickness of hardened layer is 1-2mm, the datum clamp face of slide block and the depth of parallelism between guide rail surface are less than 0.02mm/1000mm, the guide rail that has guaranteed lathe is stressed evenly, and skew and skidding do not appear in slide block in motion process, thereby the precision of overlength major diameter axle processing is guaranteed.
In addition, lathe bed of the present utility model is provided with automatic chip area and cooling device, chip removal convenience, cooling and high lubricating effect.
