Description

Technical Field

[0001] The utility model relates to the technical field of a turning-melting integrated machine, in particular to a servo motor spindle driving mechanism of the turning-melting integrated machine. Background Art

[0002] The turning-melting machine is a new product that organically combines lathes and laser heat treatment. By integrating laser equipment into the lathe, it enables heat treatment to be performed on the lathe. The turning-melting machine has huge commercial potential in the heat treatment of mechanical products.

[0003] On traditional lathes, the lathe spindle and spindle motor are typically directly connected via a half-coupling or spline mechanism. Consequently, the spindle assembly and motor are located very close together. This makes installation and removal of the spindle motor inconvenient due to the complex spindle assembly and tight spatial arrangement. Utility Model Content

[0004] In order to facilitate the disassembly and assembly of the spindle motor on the turning-melting machine, the utility model provides a servo motor spindle drive mechanism for the turning-melting machine.

[0005] The utility model provides a servo motor spindle drive mechanism for a turning and melting machine, which adopts the following technical solutions:

[0006] A servo motor spindle drive mechanism for a turning and melting machine includes a lathe spindle and a spindle motor for driving the lathe spindle, and also includes a connecting component that remotely connects the lathe spindle and the spindle motor for the spindle motor to drive the lathe spindle to rotate, and there is a disassembly and assembly gap between the lathe spindle and the spindle motor.

[0007] By adopting the above technical solution, compared with the method of directly connecting the spindle motor to the lathe spindle, the lathe spindle and the spindle motor are connected through a connecting assembly, and the lathe spindle and the spindle motor are arranged at two positions farther apart on the machine tool bed to create a disassembly and assembly gap between the lathe spindle and the spindle motor, so that when the spindle motor is disassembled and assembled on the lathe spindle, a larger operating space can be reserved for the operator, so that the operator can operate more conveniently.

[0008] Optionally, the lathe spindle includes a processing end for connecting to a processing device and a transmission end connected to the processing end and located at the tail end of the lathe bed, and the spindle motor is connected to the transmission end through the connecting assembly.

[0009] By adopting the technical scheme, the position structure of the tail part of the lathe bed is simple, the main shaft motor is arranged at the tail part of the lathe bed and connected with the lathe main shaft, and thus the operator can conveniently maintain the main shaft motor and the connecting assembly without disassembling the lathe in a large area, which is simple.

[0010] Optionally, the connecting assembly comprises a main shaft end pulley connected with the lathe main shaft, a motor end pulley connected with the main shaft motor, and a belt connecting the main shaft end pulley and the motor end pulley.

[0011] By adopting the technical scheme, the belt is used for transmission, the lathe main shaft and the main shaft motor which are far apart can be connected to adapt to the structure of the improved lathe-melting integrated machine, and the belt driving mode has the characteristics of high speed and stable operation, and is suitable for the laser heat treatment of the lathe-melting integrated machine which has high precision requirements.

[0012] Optionally, a speed reducer is arranged between the motor end pulley and the main shaft motor to reduce the speed of the main shaft motor.

[0013] By adopting the technical scheme, when the lathe-melting integrated machine performs the cladding process by laser, the lathe main shaft is in a low-speed working condition, and the speed of the main shaft motor can be reduced by arranging the speed reducer to adapt to the low-speed working condition.

[0014] Optionally, the main shaft motor is a servo motor.

[0015] By adopting the technical scheme, the main shaft motor used in the ordinary lathe is generally only suitable for high-speed working conditions, and the output speed of the main shaft motor used in the ordinary lathe is unstable in the case of low speed, while the laser processing needs the lathe main shaft to be at low speed and also has good stability, so the main shaft motor used in the ordinary lathe is not suitable for this working condition; and the servo motor can adapt to various speeds, so the servo motor is used to replace the main shaft motor of the ordinary lathe, so that the lathe-melting integrated machine can complete the high-precision operation of laser processing.

[0016] Optionally, the length of the main shaft end pulley is 15% to 25% of the length of the lathe main shaft.

[0017] By adopting the technical scheme, when the lathe main shaft is driven by the main shaft end pulley and the belt, the main shaft end pulley will generate a force to make the lathe main shaft bend, the main shaft end pulley is widened to increase the stress area between the two, thereby improving the stress condition of the lathe main shaft to reduce the deformation of the lathe main shaft.

[0018] Optionally, the number of the belts is multiple, and the belts are uniformly and interval arranged on the main shaft end pulley.

[0019] By adopting the technical scheme, the plurality of belts jointly complete the force transmission between the lathe spindle and the spindle motor, so that the force borne by a single belt is small, thereby improving the service life of the belt; and the plurality of belts can uniformly apply force to the spindle end pulley, indirectly improving the force application of the spindle end pulley to the lathe spindle, so that the lathe spindle is not prone to deformation.

[0020] Optionally, the main shaft motor is installed on the motor base, and the position of the motor base can be adjusted to adjust the tightness of the belt.

[0021] By adopting the technical scheme, the spindle motor is installed on the lathe bed through the motor base, and the position of the motor base can be adjusted on the lathe bed, so that the belt of the connecting assembly can be adjusted in tension; and since the motor base and the lathe spindle are not directly connected, when the motor base is adjusted, the lathe spindle does not need to be moved and adjusted, which is more convenient.

[0022] Optionally, the motor base is provided with a waist-shaped hole, and a fixing screw assembly is arranged in the waist-shaped hole to slidably install the motor base on the lathe bed.

[0023] By adopting the technical scheme, when the motor base is adjusted, the fixing screw assembly is loosened, and at this time the motor base can be adjusted in position through the waist-shaped hole; after adjustment is completed, the fixing screw assembly is tightened again, which is more convenient.

[0024] Optionally, the top of the motor base is provided with an adjusting assembly, the adjusting assembly comprising an adjusting block fixed to the lathe bed and an adjusting screw rotatably connected to the adjusting block and threadedly connected to the motor base to limit the motor base in the vertical direction.

[0025] By adopting the technical scheme, by arranging the adjusting block and the adjusting screw, when the fixing screw assembly is loosened, the motor base can be finely adjusted in position by rotating the adjusting screw; and because the adjusting screw limits the motor base in the vertical direction, when the fixing screw assembly is loosened, the motor base will not directly fall due to gravity, which is safer.

[0026] In summary, the utility model has at least one of the following beneficial technical effects:

[0027] 1. A lathe-melting integrated machine servo motor spindle driving mechanism, the lathe spindle and the spindle motor are arranged at two positions on the lathe bed at a distance through the connecting assembly, so that there is a disassembly gap between the two for the maintenance of the operator, thereby facilitating the disassembly and maintenance of the operator when the spindle motor is maintained;

[0028] 2. By rationally arranging the width of the spindle pulley and the number of belts, the stress on the lathe spindle can be improved and the deformation of the lathe spindle can be reduced;

[0029] 3. By using a servo motor to drive the lathe spindle, the limitation of unstable speed of traditional lathes under low speed conditions of laser heat treatment is broken, so that the turning and melting machine can also perform precision processing at low speed.

[0038] The center axis of the lathe spindle 1 and the center axis of the output shaft of the spindle motor 2 are not on the same straight line, and there is a displacement difference between the two, so there is a disassembly gap 5 between the lathe spindle 1 and the spindle motor 2, and the tail structure of the lathe bed is simple, so the operator can easily maintain the spindle motor 2.

[0039] Referring to Figure 1 Further, since the lathe integrated machine needs to be in a low-speed working condition during laser heat treatment, a speed reducer 6 is arranged between the spindle motor 2 and the connecting assembly 3, and the spindle motor 2 is speed-reduced through the speed reducer 6.

[0040] Further, in the embodiment, the spindle motor 2 is a servo motor, which can better maintain output stability at low speed and meet the requirements of laser machining.

The belt transmission connecting assembly 3 can remotely drive connect the spindle motor 2 and the lathe spindle 1, so that the spindle motor 2 and the lathe spindle 1 located at different positions of the lathe bed can better transmit power under a certain distance.

[0042] Further, since the spindle end pulley 31 has a bending deformation force on the lathe spindle 1 when the connecting assembly 3 drives the lathe spindle 1, the ratio between the length of the spindle end pulley 31 and the length of the lathe spindle 1 is designed. The length of the spindle end pulley 31 is 15% to 25% of the length of the lathe spindle 1, and in this embodiment, a ratio of 20% is selected, so that the force area between the spindle end pulley 31 and the lathe spindle 1 is larger, and the spindle end pulley 31 does not occupy a large space of the lathe spindle 1.

[0043] Further, the number of belts 33 is multiple, which are uniformly and interval arranged along the length direction of the spindle end pulley 31, so that the multiple belts 33 can uniformly apply force to the spindle end pulley 31.

By rotating the adjusting screw 432, the motor base plate 4 can be driven to move on the lathe bed.

[0046] When adjusting the tension of the belt 33, the fixed screw assembly 42 is loosened first, and then the adjusting screw 432 is rotated synchronously to make the motor base plate 4 vertically adjusted. After adjustment, the fixed screw assembly 42 is tightened again, so that the motor base plate 4 is not easy to shake.

[0047] The implementation principle of the embodiment of the servo motor main shaft driving mechanism of the car-melting integrated machine is that: the main shaft motor 2 and the lathe spindle 1 are installed at two different positions of the lathe bed, so as to leave a space between the two for the operator to maintain, and the main shaft motor 2 and the lathe spindle 1 are driven in a belt transmission mode. In the selection of the main shaft motor 2, a servo motor is selected for driving, and a speed reducer 6 is arranged at the output end of the servo motor, so that the laser equipment can run stably under low speed working condition.
