Abstract
The invention belongs to the field of machining equipment and particularly relates to a drilling unit for crankshaft drilling machines. The drilling unit is characterized by comprising a sliding table, a pushing servo motor, drilling spindles, and a drilling servo motor; the sliding table is slidably mounted on a machine tool sliding base; one end of the pushing servo motor is fixed to the machine tool sliding base, and the other end of the pushing servo motor is connected with the sliding table; the drilling spindles are rotatably mounted in the middle of the sliding table; the drilling servo motor is fixed at the top of the sliding table; the drilling servo motor is in transmission connection with the drilling spindles. The drilling unit is scientific and reasonable in structural design; two drilling spindles are provided, one motor can drive the drilling spindles to drill two workpieces at the same time, and drilling is fast and efficient; the drilling unit is high in novelty.
Description
Technical field
The invention belongs to machining apparatus field, particularly a kind of crankshaft drilling lathe units.
Background technology
There is a kind of bent axle, on it, have three holes, add and use crankshaft drilling special purpose machine tool man-hour, crankshaft drilling special purpose machine tool in the past, only have a fixture, when bent axle is carried out to bore operation, at every turn can only workpiece of clamping, can only process a hole, speed is slow at every turn, and efficiency is low.My company's independent research numerical control multi-station crankshaft drilling special purpose machine tool, can divide four groups eight workpiece to be carried out to bore operation simultaneously, the drilling equipment of drilling hole machine tool in the past, drill spindle of a driven by motor, can not meet the needs of novel lathe.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, two drill spindles of an a kind of driven by motor are provided, two bent axles are carried out to bore operation, speed is fast, efficiency is high crankshaft drilling lathe units simultaneously.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of crankshaft drilling lathe units, it is characterized in that: by slide unit, propelling servomotor, drill spindle, boring servomotor, formed, slide unit is slidably mounted on lathe slide, advance servomotor one end to be installed on lathe slide, one end is connected with slide unit, drill spindle rotates and is installed on slide unit middle part, and boring servomotor is installed in slide unit top, and boring servomotor and drill spindle are in transmission connection.
And described drill spindle is two, two drill spindles are set up in parallel in slide unit middle part, and two drill spindles are all connected with boring servo motor transmission.
Advantage of the present invention and beneficial effect are:
This crankshaft drilling lathe is reasonable by units scientific structure design, be provided with two drill spindles, a motor can drive two drill spindles to carry out bore operation to two workpiece simultaneously, bore operation speed is fast, efficiency is high, is a kind of crankshaft drilling lathe units with higher innovation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The explanation of accompanying drawing mark:
1-clamping and positioning device, 2-workpiece, 3-base, the 4-servomotor of holing, 5-drill spindle, 6-lathe slide, 7-slide unit, 8-advances servomotor.
The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of crankshaft drilling lathe units, is comprised of slide unit 7, propelling servomotor 8, drill spindle 5, boring servomotor 4, and drill spindle is two.Slide unit is slidably mounted on the lathe slide 6 on lathe base 3, advance servomotor one end to be installed on lathe slide, one end is connected with slide unit, and two drill spindles are set up in parallel in slide unit middle part, boring servomotor is installed in slide unit top, and boring servomotor and drill spindle are in transmission connection.
Operation principle of the present invention is:
The present invention is assemblied on multi-station crankshaft drilling hole machine tool, and every lathe assembles four groups.During boring, by workpiece 2(bent axle) be fixed clampingly on clamping and positioning device 1, start the boring servomotor of borehole drill construction and start and advance servomotor, boring servomotor drives drill spindle and drilling tool to hole on bent axle, advance servomotor constantly to advance slide unit to advance, eyelet is constantly deepened, until reach requirement, the control of numerical control of machine tools case stops holing and resetting automatically, and positioner to be clamped will continue boring after workpiece indexing.
Although disclose for the purpose of illustration embodiments of the invention and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the present invention and claims, various replacements, variation and modification are all possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
