Description

Technical Field

[0001] The invention relates to the field of heat treatment, in particular to a gear processing technology. Background Art

[0002] Gears are commonly used parts in mechanical transmission. The gear processing process can be roughly divided into the following stages: gear blank processing, tooth profile processing, heat treatment, tooth profile finishing, and tooth end processing. Gear blank processing is the process of heat-treated blanks entering mechanical processing. This stage is mainly to prepare for the next stage of tooth profile processing. It is mainly to process the benchmark so that the accuracy of the inner hole and end face of the tooth basically meets the specified technical requirements. Tooth profile processing is to fine-tune the shape of the gear. After this stage, a gear that fully meets the requirements of the drawing can be processed. It is necessary to process the tooth profile accuracy required for the final finishing of the tooth profile in this stage. Heat treatment is to make the tooth surface of the gear that needs to be quenched meet the specified hardness requirements. Tooth profile finishing is to further improve the tooth profile accuracy through methods such as grinding. Tooth end processing is to round, chamfer, chamfer, and deburr the tooth end of the gear. The rounded and chamfered gear is easy to mesh when sliding along the axial direction; chamfering can remove the sharp edge of the tooth end to prevent the sharp edge from breaking easily during gear transmission.

[0003] At present, in order to ensure processing efficiency, when quenching gears, most of the gears in batches are heated and then transferred to the quenching liquid for quenching. Since there are many gears in a batch, a lot of time will be consumed in the transfer operation, which will then reduce the temperature of the gears and affect the quenching effect. Summary of the invention

[0038] like Figure 1-12 As shown, a gear processing device is described in detail:

[0039] A gear processing device comprises a box body 101 with two support leg plates at the lower end, an inclined bottom plate 102 is arranged inside the box body 101, and a cross 301 with side support plates 302 symmetrically arranged on both sides, a support frame for supporting the gear is connected to the cross 301, and the outer sides of the two side support plates 302 are provided with through shafts 303, and the two through shafts 303 are respectively connected to the two side surfaces of the upper end of the box body 101, and the two side support plates 302 are provided with power connection rail frames 304, and an electromagnetic coil 602 is connected between the two power connection rail frames 304, and the electromagnetic coil 602 is sleeved on the support frame, and the gears are continuously slid through the electromagnetic coil 602 through the support frame in sequence for heating, and the gears can fall into the box body 101 for quenching after heating.

[0040] The two leg plates form a support for the box body 101, and the inclined bottom plate 102 is arranged inside the box body 101, so that the box body 101 can contain the quenching liquid;

[0041] The support frame is mounted on the cross 301 and is mounted on the upper end of the box 101 through two through shafts 303. The support frame extends on the cross 301 to the outside of the box 101, and the cross 301 is located above the upper end of the inclined bottom plate 102, so that the gear dropped into the box 101 for quenching will slide down along the inclined bottom plate 102 and move to the other side of the support frame, so that the gear after quenching is taken out of the box 101.

[0042] The support frame is used to support the gear, so that the gear can slide along the support frame toward the box body 101, and pass through the energized electromagnetic coil 602 during the sliding process, so as to heat the gear. After the gear is heated, it continues to slide toward the cross 301, and after moving to the top of the box body 101, it falls into the quenching liquid for quenching;

[0043] The two power rail racks 304 are used to be connected to a power source, so as to energize the electromagnetic coil 602 , thereby heating the gears inside the electromagnetic coil 602 .

[0044] like Figure 1-12 As shown:

[0045] The support frame includes two L-shaped seats 401 symmetrically connected to the cross 301, support rods 403 extending forward from the near ends of the two L-shaped seats 401, and a C-shaped frame 501 that rises and slides on the upper part of the cross 301, and two upper pressure plates 503 are connected to the C-shaped frame 501.

[0046] The two support rods 403 are located at the bottom and are arranged parallel to the two upper pressure plates 503 at the top, forming a limiting channel for gear sliding in the middle, and the two support rods 403 and the two upper pressure plates 503 are all located in the tooth grooves, so that the axis of the gear is parallel to the two support rods 403 and the two upper pressure plates 503, and then the gear can slide axially through the electromagnetic coil 602 in the limiting channel, so that the electromagnetic coil 602 only heats the tooth part of the gear, saving energy.

[0047] At the same time, by setting up two L-shaped seats 401, the two support rods 403 are installed. At the same time, the two support rods 403 are close to the end of the cross 301 with a certain distance, so that the gear can slide over the two support rods 403 and fall into the box body 101 due to the space formed by the extension of the two L-shaped seats 401.

[0048] Further:

[0049] The support rod 403 is damped and rotated on the L-shaped seat 401 , and an extension plate 404 is fixed to the side of the support rod 403 , and an end of the extension plate 404 extends near the end of the cross 301 .

[0050] Since the support rod 403 is installed on the L-shaped seat 401, when it is located in the tooth groove to support the gear, when the gear slides to the L-shaped seat 401, the L-shaped seat 401 will form an obstacle to the gear, thereby preventing the gear from continuing to slide. Therefore, an extension plate 404 is provided, and the extension plate 404 is inserted into the tooth groove to support the gear, and an end is extended from the end of the extension plate 404 close to the cross 301, so that the gear can slide smoothly along the extension plate 404 and pass over the L-shaped seat 401 and fall into the box body 101;

[0051] At the same time, the direction of the extension plate 404 can be adjusted by rotation through the damping rotation of the support rod 403 and the L-shaped seat 401, so as to ensure that the extension plate 404 can adapt to different gears inserted into the tooth grooves.

[0052] Further:

[0053] A bidirectional screw rod Ⅰ 402 is rotatably disposed on the cross 301 , and both ends of the bidirectional screw rod Ⅰ 402 are respectively threadedly connected to two L-shaped seats 401 .

[0054] By rotating the bidirectional screw rod I 402, the two L-shaped seats 401 can be threadedly driven to move closer or farther in the lateral direction, thereby moving the two support rods 403 closer or farther away. By coordinating the damping rotation of the support rods 403 and the L-shaped seats 401, the direction of the extension plate 404 can be rotated and adjusted, further enabling the device to adapt to the quenching processing of gears with different diameters.

[0055] Further:

[0056] A vertical screw rod 502 is rotatably mounted on the upper end of the cross 301 , and the vertical screw rod 502 is threadedly connected to the C-shaped frame 501 .

[0057] By rotating the vertical screw rod 502, the C-shaped frame 501 can be threadedly driven to move up and down, thereby driving the two upper pressing plates 503 to move up and down, further adjusting the cross-sectional size of the limiting channel, so that the device can adapt to the quenching processing of gears with different diameters.

[0058] Further:

[0059] A bidirectional screw II 504 is rotatably mounted on the C-shaped frame 501 , and both ends of the bidirectional screw II 504 are respectively threadedly connected to the two upper pressing plates 503 .

[0060] By rotating the bidirectional screw II 504, the two upper pressure plates 503 can be threadedly driven to move closer or farther away at the same time, thereby adjusting the distance between the two upper pressure plates 503, thereby ensuring that the two upper pressure plates 503 can be inserted into the tooth grooves of gears with different diameters, ensuring the axial movement of the gears in the limiting channel, and ensuring that the electromagnetic coil 602 only heats the teeth of the gears, saving energy.

[0061] Further:

[0062] A horizontal plate 104 is fixed to the upper end of the box body 101 , and a tightening screw 105 is rotatably mounted on the horizontal plate 104 , and the tightening screw 105 tightens the lower end of the cross 301 .

[0063] By rotating the tightening screw 105, the lower end of the cross 301 can be pushed, so that the lower end of the cross 301 can rotate on the box 101 through the two through shafts 303, thereby adjusting the inclination angle of the limiting channel, so that the device can adapt to different gears, so that the gear can automatically slide axially in the limiting channel through the electromagnetic coil 602 for heating until it falls into the box 101, completing quenching, and improving the degree of automation of the device.

[0064] like Figure 1-12 As shown:

[0065] The two power rail frames 304 are both vertically slidably provided with connection blocks 601 , and the two ends of the electromagnetic coil 602 are respectively connected to the two connection blocks 601 , and the two connection blocks 601 are both threadedly connected with positioning screws 603 .

[0066] The electromagnetic coil 602 slides on the two power rail frames 304 through the two connecting blocks 601, so as to adjust the position of the electromagnetic coil 602 so that the axis of the electromagnetic coil 602 coincides with the axis of the gear to be heated, thereby ensuring the heating effect;

[0067] The positioning screw 603 can press against the power rail frame 304 to form a relative fixation between the power rail frame 304 and the connecting block 601;

[0068] At the same time, through the above arrangement, it is easy to replace the electromagnetic coil 602, so that the inner diameter of the electromagnetic coil 602 can match the diameter of the gear to be heated, thereby ensuring the heating efficiency.

[0069] like Figure 1-12 As shown:

[0070] A through hole 103 is provided at the lower part of the inclined bottom plate 102, and a lifting box 201 is lifted and slid in the through hole 103. A crankshaft 203 rotates between two leg plates at the lower end of the box body 101, and a linkage plate 202 rotates between the eccentric part of the crankshaft 203 and the inside of the lifting box 201.

[0071] The motor installed on the leg plate transmits the crankshaft 203, so that the crankshaft 203 can drive the lifting box 201 to lift and lower in the through hole 103 through the linkage plate 202. When the lifting box 201 is at the bottom, the upper end surface of the lifting box 201 is integrated with the upper surface of the inclined bottom plate 102, so that the gear can slide to the upper end of the lifting box 201. When the lifting box 201 is at the top, the upper end surface of the lifting box 201 pushes the gear out of the quenching liquid, and is affected by the inclination of the upper end surface of the lifting box 201, and automatically slides out of the box 101 from the end away from the support frame, completing the automatic disengagement of the gear, further improving the automation of the device;

[0072] There is a gap between the lifting box 201 and the side of the box body 101 away from the support frame end, so that when the lifting box 201 rises, the quenching liquid carried by it flows back into the box body 101;

[0073] At the same time, the reciprocating lifting of the lifting box 201 can stir the quenching liquid and dissipate the heat of the quenching liquid.

[0074] like Figure 1-12 As shown:

[0075] The processing technology using the gear processing device comprises the following steps:

[0076] S1, energize the electromagnetic coil 602;

[0077] S2, making the gears slide through the electromagnetic coil 602 in sequence through the support frame;

[0078] S3. After being heated by the electromagnetic coil 602, the gear falls into the box 101 for quenching.
