Description

Cutter with double saw bits variable pitch device
Technical field
The present invention relates to a kind of cutter with double saw bits variable pitch device, particularly relate to a kind of device changing cutter with double saw bits saw blade spacing.
Background technology
At present, known cutter with double saw bits spacing is fixed, and cause the material specification of cutting single, and to prepare the extensive use in test specimen along with cutting machine in scientific experiment, the cutting machine of traditional this constant spacing can not meet the requirement of many sizes cutting.Along with the wearing and tearing of saw blade, need to change or maintenance, traditional cutting machine can not address these problems in time, needs professional and technical personnel to operate, seriously reduces operating efficiency.
Summary of the invention
Can not adjust the deficiency of spacing between saw blade in order to overcome existing cutter with double saw bits, the invention provides a kind of cutter with double saw bits variable pitch device, this device can not only change the spacing between two saw blades as required.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cutter with double saw bits variable pitch device, is arranged on cutter with double saw bits, and cutter with double saw bits comprises cutting axis, the first saw blade and the second saw blade, and the first saw blade is fixed on cutting axis; This cutter with double saw bits variable pitch device comprises low frequency motor, pushing ram, pole, sleeve pipe, fixture, cutting axis and numerical control device; Wherein, described casing pipe sleeve is on cutting axis, and the internal via shape of sleeve pipe and the cross section of cutting axis are octagon; Second saw blade is fixed on sleeve pipe, and sleeve pipe two ends all have flange, and two flanges are fixedly connected with a fixture respectively; Radial direction away from the flange of the first saw blade has two symmetrical grooves, each insertion one pole on two grooves, every root pole is fixedly connected with a pushing ram parallel with cutting axis, every root pushing ram is coupled with the internal thread of a low frequency motor, and two low frequency motor are all connected with numerical control device.
The invention has the beneficial effects as follows:
1, the present invention can realize the adjustment of cutting machine saw-piece spacing quickly and easily, five kinds, the screw thread that have employed in device in sleeve pipe and cutting axis, flange and C-type clamp tool, C-type clamp tool and cutting axis, pole and flange, pushing ram and low frequency motor agrees with structure, accurately realizes displacement requirement.
2, cutting axis adopts octagon, compensate for the defect of circular section axle carry-over moment ability.
3, on cast-cutting saw slice fixing cutting axis, one is fixed on sleeve pipe, is realized the change of saw blade spacing by the movement of sleeve pipe on cutting axis.
4, the upper and lower C-type clamp tool of sleeve pipe homonymy is in firmly or slidably state with the clamping of screw rod on it and the lax sleeve pipe that decides, simple to operate.
5, adopt numerical control device to control low frequency motor revolution, and then produce the corresponding displacement of sleeve pipe, accurately can realize the change of saw blade spacing.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutter with double saw bits variable pitch device of the present invention; In figure, low frequency motor 1, pushing ram 2, pole 3, sleeve pipe 4, first saw blade 5, second saw blade 6, fixture 7, cutting axis 8.
Detailed description of the invention
As shown in Figure 1, cutter with double saw bits variable pitch device of the present invention is arranged on cutter with double saw bits, and cutter with double saw bits comprises cutting axis 8, first saw blade 5 and the second saw blade 6, first saw blade 5 is fixed on cutting axis 8.This cutter with double saw bits variable pitch device comprises low frequency motor 1, pushing ram 2, pole 3, sleeve pipe 4, fixture 7, cutting axis 8 and numerical control device, sleeve pipe 4 is enclosed within cutting axis 8, the internal via shape of sleeve pipe 4 and the cross section of cutting axis 8 are octagon, with ensure sleeve pipe 4 can along the smooth-going slippage of cutting axis 8 and radial direction do not produce and rock; Second saw blade 6 is fixed on sleeve pipe 4.Sleeve pipe 4 two ends all have flange, two flanges are fixedly connected with the fixture 7 of the radial direction of a C type respectively by screw rod, radial direction away from the flange of the first saw blade 5 have two symmetrical grooves, each insertion one pole 3 on two grooves, every root pole 3 is fixedly connected with a pushing ram 2 parallel with cutting axis 8, every root pushing ram 2 is coupled with the internal thread of a low frequency motor 1, and two low frequency motor 1 are all connected with numerical control device.
Numerical control device can be realized by ordinary PC, single-chip microcomputer etc., controls low frequency motor 1 and rotates, and drives pushing ram 2 advance or retreat, makes the pole 3 be connected with pushing ram 2 advance or retreat, and then promotion sleeve pipe 4 moves on cutting axis 8, realizes spacing adjustment.
The course of work of the present invention is as follows: before cutting, the distance values of needs is inputted in numerical control device, numerical control device controls low frequency motor 1 and rotates certain revolution N forward or backwards, pushing ram 2 advances by being coupled with low frequency motor 1 or retreating displacement S1, and promotes sleeve pipe 4 by pole 3 and produce same displacement S1.The current distance of the second saw blade 6 that the first saw blade 5 fixing on cutting axis 8 is movable on cutting axis 1 is S, then S ± S1 is the saw blade distance needed.When sleeve pipe 4 stops mobile, on clamping C-type clamp tool 7, screw rod makes sleeve pipe 4 entirety be fixed on cutting axis 1.Close numerical control device and low frequency motor 1, pole 3 shifts out the groove on flange, and test specimen is in place, can cut.
Cutter with double saw bits variable pitch device of the present invention agrees with structure by multiple, realizes the accurate transfer of displacement.The present invention can realize the adjustment of cutting machine saw-piece spacing quickly and easily, five kinds, the screw thread that have employed in device in the fixture 7 of flange with C type of sleeve pipe 4 and cutting axis 1, sleeve pipe 4, fixture 7 and cutting axis 1, the flange of pole 3 and sleeve pipe 4, pushing ram 2 and low frequency motor 1 agrees with structure, accurately realizes displacement requirement.
In the present invention, cutting axis 1 adopts octagon, compensate for the defect of circular section axle carry-over moment ability.Cast-cutting saw slice one is fixed on cutting axis 1, and one is fixed on sleeve pipe 4, is realized the change of saw blade spacing by the movement of sleeve pipe 4 on cutting axis 1.The upper and lower C-type clamp tool 7 of sleeve pipe 4 homonymy is in firmly or slidably state with the clamping of screw rod on it and the lax sleeve pipe 4 that decides, simple to operate.Numerical control device controls the revolution of low frequency motor 1, and then produces the corresponding displacement of sleeve pipe 4, accurately can realize the change of spacing between the first saw blade 5 and the second saw blade 6.
