Description

Technical Field

[0001] The utility model relates to the technical field of internal gear ring quenching, in particular to an internal gear ring quenching device. Background Art

[0002] The inner ring gear refers to the internal gear on the same axis as the planetary carrier in the planetary gear transmission. The inner gear is an annular mechanical element with a smooth outer ring and teeth on the inner ring. It is mainly used in torque transmission mechanisms that transmit torque and speed. It is also widely used in various mechanical devices. In the processing of the inner ring gear, the inner ring gear needs to be heat treated after machining to enhance its surface strength and wear resistance. At present, the common heat treatment method is high-frequency quenching. High-frequency quenching is mostly used for surface quenching of industrial metal parts. It is a metal surface treatment method that generates a certain amount of induced current on the surface of the product workpiece, rapidly heats the surface of the part, and then rapidly quenches it. In the prior art, in order to reduce the deformation of the inner gear ring during the quenching process, continuous induction quenching is often performed on the inner gear ring part. During the quenching process, the angle of the inner gear ring is continuously adjusted so that the induction coil enters the tooth grooves of the inner gear ring in sequence, which can greatly improve the quenching quality of the inner gear ring. However, some quenching devices have a small application range and can only quench an inner gear ring of one size. Even if some quenching devices can quench inner gear rings of multiple sizes, when the inner gear ring is fixed, the staff needs to adjust the clamping component according to the size of the inner gear ring, which takes a long time to adjust, increasing the time required for quenching.

The current generator 4 transmits high-frequency current to the induction coil 7, so that a high-frequency magnetic field is generated around the induction coil 7, and the inner gear ring is quickly heated. A quenching coolant nozzle 8 is provided in the middle of the arc plate on the rear side of the shell 3. The quenching coolant nozzle 8 is an electromagnetic nozzle. The part of the inner gear ring after heating is completed will rotate to the position of the quenching coolant nozzle 8, and the quenching coolant nozzle 8 will be started to spray the quenching coolant to the inner gear ring to cool the inner gear ring and realize the quenching of the inner gear ring. A PLC controller 10 is provided on the surface of the base 1 to control the start and stop of the entire device.

The slide grooves 92 distributed in annular shapes are all slidably connected with clamping plates 93. The three clamping plates 93 distributed in annular shapes slide in the slide grooves 92 synchronously and with the same amplitude to clamp the inner gear ring so that the inner gear ring is fixed on the hollow turntable 91. It is suitable for inner gear rings of different sizes. The clamping and rotating mechanism 9 also includes a turntable 94 and a stepping motor 95. The turntable 94 is rotatably connected to the inside of the hollow turntable 91. The sliders at the lower ends of the clamping plates 93 are all slidably connected to the plane spiral grooves on the surface of the turntable 94. The stepping motor 95 is arranged on the base 1 At the lower end, the output shaft of the stepper motor 95 passes through the through hole on the surface of the hollow turntable 91 and is fixedly connected to the middle of the turntable 94. The input end of the stepper motor 95 is electrically connected to the output end of the PLC controller 10. The stepper motor 95 is started, and the output shaft of the stepper motor 95 drives the turntable 94 to rotate, so that the slider at the lower end of the clamping plate 93 slides in the plane spiral groove on the surface of the turntable 94, providing power for the movement of the clamping plate 93. When the clamping plate 93 clamps the inner gear ring, the rotation of the turntable 94 will drive the hollow turntable 91 to rotate together. The clamping and rotating mechanism 9 also includes a corrugated groove 96 and a positioning assembly 97. The corrugated groove 96 is arranged on the outer arc surface of the hollow turntable 91. The positioning assembly 97 includes a guide column 971 and a positioning plate 972. The guide column 971 is respectively arranged on the base 1 Between the upper and lower inner walls, the outer arc surface of the guide column 971 is vertically slidably connected with a positioning plate 972, and the sliding columns on the surface of the positioning plate 972 are slidably connected with the inside of the corrugated groove 96. During the rotation of the hollow turntable 91, the sliding column of the positioning plate 972 slides inside the corrugated groove 96, so that the positioning plate 972 moves back and forth up and down. The moving directions of the two adjacent positioning plates 972 are opposite. The vertical position of the positioning plate 972 will change with the rotation of the hollow turntable 91. By limiting the vertical position of the positioning plate 972, the angle of the hollow turntable 91 is determined by using the two adjacent positioning plates 972. The positioning assembly 97 also includes a spring 973, which is respectively arranged between the positioning plate 972 and the top wall of the base 1, and the spring 973 is movably sleeved on the guide column The outer arc surface of 971 increases the friction between the sliding column of the positioning plate 972 and the corrugated groove 96, and increases the power required for the rotation of the hollow turntable 91. The positioning component 97 also includes a limit push rod 974 and a slide plate 975. The limit push rod 974 is respectively arranged on the outer edge of the base 1. The lower end of the telescopic end of the limit push rod 974 is provided with a slide plate 975. The slide plate 975 is slidably connected to the guide column 971. The input end of the limit push rod 974 is electrically connected to the output end of the PLC controller 10. The limit push rod 974 is started, and the telescopic end of the limit push rod 974 drives the slide plate 975 to move up and down to limit the movement of the positioning plate 972. The splints 93 are all L-shaped splints, and the lower surface of the horizontal plate of the splint 93 is an inclined surface, so that the splint 93 can clamp the inner gear rings of different thicknesses.

[0025] The working principle of the internal gear ring quenching device provided by the utility model is as follows: during quenching, the internal gear ring is placed on the surface of the hollow turntable 91, and the stepper motor 95 is started by the PLC controller 10. Under the elastic force of the spring 973, the friction between the sliding column of the positioning plate 972 and the corrugated groove 96 is increased, and the power required for the rotation of the hollow turntable 91 is increased. Therefore, at this time, the output shaft of the stepper motor 95 will drive the turntable 94 to rotate, so that the slider at the lower end of the clamping plate 93 slides in the planar spiral groove on the surface of the turntable 94, and the three clamping plates 93 distributed in an annular manner slide in the sliding groove 92 with the same amplitude to clamp the internal gear ring so that the internal gear ring is fixed on the hollow turntable 91, which is suitable for internal gear rings of different sizes. Then, as the output shaft of the stepper motor 95 continues to rotate, the elastic force of the spring 973 is overcome, and the hollow turntable 91 and the internal gear ring are driven to rotate at a fixed angle, and the sliding column of the positioning plate 972 slides in the corrugated groove 96, so that the positioning plate 972 The outer arc surface of the guide column 971 reciprocates up and down, and the vertical position of the positioning plate 972 will change with the rotation of the hollow turntable 91. When the hollow turntable 91 stops rotating, the limit push rod 974 is started, and the telescopic end of the limit push rod 974 drives the slide plate 975 to move up and down, thereby limiting the movement of the positioning plate 972, so that the rotation angle of the inner gear ring is more accurate. When the inner gear ring stops rotating, the electric push rod 5 is started, and the telescopic end of the electric push rod 5 drives the adjustment block 6 and the induction coil 7 to move downward, so that the induction coil 7 enters the tooth groove of the inner gear ring, and the high-frequency current generator 4 is started. The high-frequency current generator 4 transmits high-frequency current to the induction coil 7, so that a high-frequency magnetic field is generated around the induction coil 7, and the inner gear ring is quickly heated. The part of the inner gear ring after heating is rotated to the position of the quenching coolant nozzle 8, and the quenching coolant nozzle 8 is started to spray the quenching coolant to the inner gear ring to cool the inner gear ring and realize the quenching of the inner gear ring.

[0026] It is worth noting that the PLC controller 10 disclosed in the above embodiment can use the NX7 model PLC controller, and the linear motor 2, the high-frequency current generator 4, the electric push rod 5, the quenching coolant nozzle 8, the stepper motor 95 and the limit push rod 974 can be freely configured according to the actual application scenario.
