Description

Technical Field

It is commonly used in various mechanical equipment, and gear transmission is one of the most widely used mechanical transmission methods in modern equipment. It has the advantages of high accuracy, high efficiency, compact structure, reliable operation, and long service life.

[0003] In the process of manufacturing gears, generally, the metal material used to prepare the gears is first made into a ring shape, and grooves are formed on the inner wall of the ring material to facilitate the coaxial fixed connection between the gear and the external driving structure. Subsequently, gear hobbing is used to cut the outer wall of the gear ring to form multiple convex teeth on the outer wall of the gear.

[0023] Reference Figure 1 , Figures 6 - 18, a driving mechanism 400 is provided in the middle of the rotating groove 110.

[0024] Reference Figures 1 - 18Working principle: The staff can pre-process the gear material to be processed, and then put the processed gear material to be processed on the outside of the fixed seat 320. A protrusion is set on the upper part of the circumferential outer wall of the fixed seat 320. This protrusion is designed according to the structure of the hole in the middle part of the gear material to be processed, so as to ensure that the gear material to be processed can rotate with the fixed seat 320 in this device, and an annular protrusion is also set in the middle part of the fixed seat 320. The diameter of the annular protrusion is much larger than the diameter of the gear material to be processed. This design is to support the gear material to be processed, so that there is a certain distance between the gear material to be processed and the top surface of the conveying disc 310, so as to prevent the cut waste from affecting the cutting of the material by the gear insert 211.

[0025] After the gear material to be processed is fixed, the staff can use the motor 220 to drive the rotating shaft 221 to rotate. During the rotation, the rotating shaft 221 will squeeze the guide block 212 through the annular curved groove 222, so that the movable disk 210 fixed with the guide block 212 moves, but the movable disk 210 is restricted by the fixed frame 230 and cannot rotate. Therefore, under the control of the guide block 212 and the annular curved groove 222, the movable disk 210 will reciprocate up and down. During the movement, the toothing 211 will contact the gear material to be processed set on the fixed seat 320 and cut its circumferential outer wall, so as to cut out the convex teeth of the outer wall of the gear. The lower end of the toothing 211 is set as a cutter head with a pointed end downward, which makes it easier for the toothing 211 to break the top wall of the gear material to be processed. When the gear inserting 211 passes through the gear material to be processed, the extrusion rod 260 and the fixing rod 250 will also enter the circular cavity 322, but the extrusion rod 260 will squeeze the arc plate 323 from top to bottom, which will drive the fixing seat 320 to rotate in the direction restricted by the ratchet 340 and the pawl 350. Therefore, the fixing seat 320 will not rotate. On the contrary, the extrusion rod 260 will be squeezed by the top surface of the arc plate 323. Because the bottom surface of the extrusion rod 260 close to the movable disk 210 is an inclined surface, the arc plate 323 can easily guide the extrusion rod 260 in the direction of the support spring 270, and then the extrusion rod 260 will be staggered with the arc plate 323 until it moves to the bottom of multiple arc plates 323 and is then supported by the support spring 270 and restored to its original position.

[0026] After the gear shaper 211 passes through the raw material of the gear to be processed, a round of convex teeth is completed on the side wall of the raw material of the gear to be processed corresponding to the position of the gear shaper 211. Subsequently, the gear shaper 211 will rise with the movable disk 210. In the initial stage of the rise, the gear shaper 211 will pass through the groove after cutting. When the height of the gear shaper 211 is higher than the raw material of the gear to be processed, the position of the extrusion rod 260 will enter the gap between the two arc-shaped plates 323 corresponding to it. Then, the extrusion rod 260 will exert extrusion on the bottom surface of the arc-shaped plate 323 directly above it. At this time, the driving force generated by the extrusion contact between the two on the fixed seat 320 is not restricted by the ratchet 340 and the pawl 350. Therefore, the fixed seat 320 will drive the raw material of the gear to be processed to rotate together, and rotate the unprocessed position adjacent to the processing position on the raw material of the gear to be processed to the position of the gear shaper 211; In the above reciprocating processing, the raw material of the gear to be processed will keep rotating with the fixed seat 320 until it rotates more than one circle. During the rotation, the transmission gear 330 coaxially and fixedly connected to the lower end of the fixed seat 320 will deflect the tooth column 412, and then the turntable 410 provided with the tooth column 412 will rotate. At this time, the insertion rod 430 on the bottom surface of the turntable 410 is received in the bottom groove 413, and the compression spring 440 is also in a compressed state. However, when the turntable 410 is deflected by the fixed seat 320, the guide rod 431 on the bottom surface of the insertion rod 430 moves from front to back along the first guide groove 113. In this way, the guide rod 431 will be blocked by the baffle 117 at the junction of the first guide groove 113 and the second guide groove 114 and cannot enter the second guide groove 114, and can only deflect backward along the first guide groove 113 with a constant diameter. Under the restriction of the inner wall of the first guide groove 113, the insertion rod 430 will not pop out of the bottom groove 413. By setting the number of tooth columns 412 in this device, after the fixed seat 320 rotates one circle and exceeds a part, the turntable 410 will rotate 90 degrees and drive the guide rod 431 to move to the junction of the connecting groove 115 and the first guide groove 113. Such a design is to ensure that the outer wall of the raw material of the gear to be processed can fully receive the processing of the gear shaper 211 and complete the processing of one round of teeth.

[0027] After the guide rod 431 corresponds to the connecting groove 115, it will quickly pop out under the resilience of the compression spring 440 and move to the junction of the connecting groove 115 and the second guide groove 114. The insertion rod 430 will also insert into the insertion slot 324 accordingly. At the same time, the end of the insertion rod 430 will exert extrusion on the end of the movable rod 450 on the side close to the turntable 410. Subsequently, the movable rod 450 will move outward and exert extrusion on the top surface of the extrusion groove 461 through its end away from the turntable 410. Then, the limiting rod 460 will rise and move out of the limiting groove 112. Next, the restriction on the conveying disk 310 will be released. The torsion spring 420 provided in the circular groove 411 on the bottom surface of the turntable 410 has been tightened during the rotation of the turntable 410 with the fixed seat 320. During the rotation, because the conveying disk 310 is restricted by the limiting rod 460 and the limiting groove 112, and the fixed seat 320 is restricted by the ratchet 340 and the pawl 350, the turntable 410 can never rotate back under the action of the torsion spring 420. At this time, the torsion spring 420 that loses the restriction will release the rotational force to drive the turntable 410 to rotate and drive the conveying disk 310 to rotate together through the insertion rod 430. In this way, the fixed seat 320 located at the rear will be rotated to the lower part of the gear cutting mechanism 200 and wait to be processed. The raw material to be processed, which is separated from the processed gear by one, will rotate to the position where the rear limiting groove 112 is located. It should be noted that a gentle slope with gradually decreasing circular arc height is provided on the side wall of the limiting groove 112 far from the gear cutting mechanism 200. The limiting rod 460 rotating towards it will gradually insert into the limiting groove 112 along the gentle slope. The side wall of the limiting groove 112 close to the gear cutting mechanism 200 is vertically arranged, so as to fully restrict the rotation of the conveying disk 310 and avoid the rotational force exerted by the torsion spring 420 on the transmission gear 330 through the tooth column 412 from causing the rotation of the conveying disk 310.

[0028] During the rotation of the conveying disk 310 driven by the insertion rod 430, it will rotate to the front along the second guide groove 114. The shortest distance between the inner side wall of the second guide groove 114 and the circumferential outer wall of the turntable 410 gradually decreases. In this way, the insertion rod 430 will be gradually pressed into the bottom groove 413 during the forward rotation. Since the inner wall of the insertion slot 324 where the insertion rod 430 exerts thrust is a plane structure, there will be no problem that the insertion rod 430 disengages from the insertion slot 324 during rotation. The other side wall is set as an arc surface to facilitate the insertion rod 430 being blocked when moving along the first guide groove 113. Through the arc surface, the insertion rod 430 can be further retracted into the bottom groove 413 to adapt to the position. When the guide rod 431 enters the overlapping position of the first guide groove 113 and the second guide groove 114 from the second guide groove 114, it will first push open the baffle 117. The range of the first guide groove 113 is available for the baffle 117 to rotate, so the baffle 117 will not affect the forward movement of the guide rod 431. After the guide rod 431 passes over the position of the baffle 117, the baffle 117 will reset under the action of the coil spring 118 to block the guide rod 431 during the subsequent movement of the guide rod 431.

[0029] Finally, the staff only needs to remove the processed gear from the front side. During the gear processing, the staff only needs to operate two things: sleeving the gear to be processed outside the fixed seat 320 and removing the processed gear, and there is no need to stop the device during the operation.
