Abstract
The utility model relates to a cutting spiral groove milling machine, comprising a body, a spindle support, a milling head, a transmission mechanism and a motor; wherein, the transmission mechanism comprises a secondary reducing device connected with the motor, a frequency converter and forked wormgear pair fixed on the spindle support; a plurality of gears and a change gear plate are fixed on the spindle support; the secondary reducing device comprises a reducer connected with the motor and a belt conveyer connected with the reducer. The cutting spiral groove milling machine avoids destroying the machining performance and range of the machine tools and enables machining of spiral grooves by adding auxiliary transmission elements. The cutting spiral groove milling machine has the advantages of simple structure, convenient operation, low machining cost and easy popularization and application.
Description
(1) technical field
The utility model relates to the milling equipment technical field, particularly a kind ofly is used to process spiral fluted cutting screw helical flute mining machine.
(2) background technology
At present, people process helicla flute and generally adopt equipment such as lathe, universal milling machine, these equipment mechanism complexity, and complicated operating process, equipment cost, using is not easily, and the range of work is restricted.
Winch is the lifting means that national all kinds of mining activities is used, and the drum diameter that winch generally utilizes is bigger, and the circular arc spiral drum slot is arranged on the cylindrical, grooving pitch is bigger, grooving is gone into cutter and withdrawing all can not threaded empty cutter, does not have suitable equipment, and processing is the comparison difficulty.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, provide a kind of simple in structure, cost is lower, can machining large workpiece and special spiral fluted cutting screw helical flute mining machine.
The utility model is realized by following measure: a kind of cutting screw helical flute mining machine, comprise lathe bed, spindle carrier, milling head, transmission mechanism, motor, the branch tooth worm gear that described transmission mechanism comprises two reduction gear, the frequency converter that links to each other with motor and is fixed on spindle carrier, described spindle carrier also is fixed with a plurality of gears and quadrant plate.
The further improvements of the utility model are: described two reduction gear comprises the reductor that links to each other with motor, the belt transmission mechanism that links to each other with reductor.
The beneficial effects of the utility model:
1. do not destroy the processing characteristics and the range of work of lathe itself, only increase some attached driving members that help, just can realize spiral fluted processing;
2. on the basis of original lathe, increase quadrant plate and change gear, realized special spiral fluted processing technology; Improved transmission system and met machining speed with the rotation that realizes workpiece.
3. simple in structure, easy to operate, processing cost is low, suitable applying.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model clamping workpiece schematic diagram.
1 milling head among the figure, 2 lathe beds, 3 spindle carriers, 4 fens tooth worm gears, 5 motors, 6 reductors, 7 frequency converters, 8 quadrant plates, 9 workpiece, 10 belt transmission mechanisms, 11 supporting disks, 12 bearing bracket stands.
(5) specific embodiment
A kind of cutting screw helical flute mining machine as shown in Figure 1, comprise lathe bed 2, spindle carrier 3, milling head 1, transmission mechanism, motor 5, described transmission mechanism comprises two reduction gear, frequency converter 7 that links to each other with motor 5 and the branch tooth worm gear 4 that is fixed on spindle carrier 3, and described spindle carrier 3 also is fixed with a plurality of gears and quadrant plate 8; Described two reduction gear comprises the reductor 6 that links to each other with motor 5, the belt transmission mechanism 10 that links to each other with reductor 6.
To the clamping of large-scale workpiece 9, adopt two supporting disks 11 to fix as shown in Figure 2, an end is provided with on the floral disc that the hole directly is sleeved on lathe, and the other end is fixing with bearing bracket stand 12.
Below in conjunction with an object lesson the utility model course of work is described: the processing diameter is 2536mm, the helicla flute workpiece material of pitch 54.5mm: medium carbon steel hardness: HB200, this workpiece characteristics are: workpiece is big, helicla flute pitch is special, difficult clamping at engine lathe, all can not be processed on numerically controlled lathe and the milling machine, can utilize the utility model processing, process is as follows:
1. cutter and material thereof chooses (calculating by diameter 30mm during calculating), the cotter mill cutter of high-speed steel (twolip)
2. feed engagement 0.12mm
3. the cutting speed of cutter is pressed 36m/min, and then the milling length of per minute is:
36m/min÷(30×π)mm×2×0.1?2mm≈92mm/min
4. calculating drum speed
92mm/min÷(2536×π)mm/r≈0.012r/min
5. be 200 in conjunction with lathe from the speed ratio of status tooth worm gear 4 according to above requirement, select the motor of 3KW950r/min, speed ratio is 37.9 reductor, and 10 times frequency converter and speed ratio are 3 one-level belt transmission, satisfies machining and requires:
950 * (1/37.9) * (1/200) * (1/3) * (frequency converter speed ratio 1～1/10) ≈ 0.04～0.004 (r/min)
6. calculate the gear ratio that is connected change gear between main shaft and the milling head leading screw.Leading screw pitch is 10mm
54.5/10=5.45 decomposing gear ratio is 109/20
Through above-mentioned steps, with motor, the reductor that chooses, 10 times frequency converter and speed ratio are that 3 one-level belt assembles by shown in Figure 1, then milling cutter are fixed, and clamping workpiece is good, cut screw helical flute mining machine and just can work.
