Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples: the invention provides a full-automatic forging device for high-strength gear blanks, which comprises a gear hobbing machine 1, a transverse moving mechanism 2, a longitudinal pushing mechanism 3, a pressing mechanism 4, a rotating seat 5, a jacking mechanism 6 and a gear 7 to be machined, wherein the gear hobbing machine 1 is used for hobbing the gear 7 to be machined, the longitudinal pushing mechanism 3 is fixedly arranged on a horizontal moving table of the gear hobbing machine 1, the gear 7 to be machined is driven by the horizontal moving table to transversely approach or separate from a hob 1a, the longitudinal pushing mechanism 3 is used for longitudinally driving the gear 7 to be machined to move along the length direction of the hob 1a, the transverse moving mechanism 2 is arranged at the top of the longitudinal pushing mechanism 3, the transverse moving mechanism 2 is used for transversely driving the gear 7 to be machined to approach or separate from the hob 1a, the jacking mechanism 6 is fixedly arranged at the top of the transverse moving mechanism 2, the jacking mechanism 6 is used for jacking the gear 7 to be machined to be contacted with the hob 1a, the rotating seat 5 is fixedly arranged at the top of the jacking mechanism 6, the rotating seat 5 is used for driving the gear 7 to be machined to be rotationally machined with the hob 1a, the pressing mechanism 4 is arranged on the vertical moving mechanism 1b, and the pressing mechanism 4 is arranged at the top of the vertical moving mechanism 4 is used for pushing the pressing mechanism 4 to be vertically upwards to be machined when the pressing mechanism 4 is connected with the pressing mechanism 4. During gear hobbing, the gear 7 to be machined is lifted upwards through the lifting mechanism 6, wherein during lifting, the gear 7 to be machined and the hob 1a rotate, namely, when the gear 7 to be machined contacts with the hob 1a, gear hobbing is performed between the gear 7 to be machined and the hob, along with continuous lifting of the gear 7 to be machined, and when the bottommost part of the gear 7 to be machined is cut out of a tooth slot, the gear 7 to be machined is driven to be machined. The undercut described hereinafter has the same meaning as the hobbing.
However, the gear 7 to be machined is less accurate due to abrasion caused by long-term use of the hob 1a. For this purpose, the gear 7 to be machined is kept at the height, the gear 7 to be machined is pushed away from the hob 1a by the transverse moving mechanism 2, the gear 7 to be machined is pushed to move along the length direction of the hob 1a by the longitudinal pushing mechanism 3, the gear 7 to be machined is driven to reset by the transverse moving mechanism 2, and when the gear 7 to be machined is reset, the gear 7 to be machined is contacted with the hob 1a, but the contacted position is changed, namely the tooth position of the hob 1a contacted with the gear 7 to be machined is changed. If the initial contact position of the hob 1a is not worn, the hob 1a is no longer in contact with the gear 7 to be machined in the subsequent contact. If the gear to be machined is in conflict, the gear to be machined 7 is machined again through rotation of the hob 1a and the gear to be machined 7.
Wherein, the rotation of the gear 7 to be processed is driven to rotate through the rotating seat 5. In this solution, the lateral movement mechanism 2 may be driven by an electric sliding table type of linear drive.
If the lateral movement mechanism 2 adopts the driving mode of the electric sliding table, the screw rod is used by the inner structure, and the long-term gear 7 to be processed is extruded by the hobbing cutter 1a, a large lateral force is applied, which reduces the precision of the lateral movement mechanism 2, and the precision of the lateral movement mechanism 2 directly influences the subsequent re-processing of the gear. The distance between the gear 7 to be machined and the hob 1a which are transversely moved and separated is smaller, if an electric control driving mode is adopted, the time is more, and the subsequent re-machining times are not limited to one time or two times, so that more manufacturers need to design the gear, but if the gear is electrically controlled, the time consumption is more, and the gear is not beneficial to large-batch machining. Therefore, in order to explain the above two problems, a new transverse moving mechanism 2 is proposed, wherein, as shown in fig. 2 and 3, the transverse moving mechanism 2 includes an elastic reset mechanism 2a, an abutting displacement mechanism 2b, an inserting column 2c, a transverse sliding plate 2d and a contact plate 2e, the transverse sliding plate 2d is installed on a longitudinal displacement seat of the longitudinal pushing mechanism 3 in a transversely horizontal sliding manner, a sliding block is arranged at the bottom of the transverse sliding plate 2d, a sliding groove matched with the sliding block is arranged at the top of the longitudinal pushing mechanism 3, one side of the transverse sliding plate 2d is provided with an abutting displacement mechanism 2b, the contact plate 2e is fixedly connected with the transverse sliding plate 2d, the contact plate 2e abuts against the abutting displacement mechanism 2b, when the longitudinal pushing mechanism 3 longitudinally pushes the contact plate 2e against the abutting displacement mechanism 2b, so that the transverse sliding plate 2d transversely moves, namely drives a gear 7 to be machined to be transversely separated from a hob 1a, the elastic reset mechanism 2a is fixedly installed on the longitudinal displacement seat of the longitudinal pushing mechanism 3, the elastic reset mechanism 2a is used for applying an elastic force to the transverse moving mechanism 2 to be close to the abutting against the displacement mechanism 2b, after the gear 7 is separated from the hob 1a by the elastic reset mechanism 2a, and the hob 7 is elastically pressed against the hob 2a to be machined again, and the hob 2b can be machined by the elastic reset mechanism 2 a. Namely, by replacing the approach or the separation between the gear 7 to be processed and the hob 1a by the electric control, the speed is faster, and the time spent for batch processing is saved. The inserting column 2c is fixedly arranged on a lifting seat of the jacking mechanism 6, a first through hole for the inserting column 2c to pass through is formed in the transverse sliding plate 2d, and a second through hole for the inserting column 2c to pass through is formed in a longitudinal displacement seat of the longitudinal pushing mechanism 3;
when the jacking mechanism 6 and the gear 7 to be processed are both positioned at the initial positions, the inserting column 2c is inserted into the first perforation and the second perforation, so that the transverse sliding plate 2d and the longitudinal pushing mechanism 3 form a whole, the pushing force of the hob 1a and the gear 7 to be processed, which are received by the transverse moving mechanism 2, is conducted on the longitudinal pushing mechanism 3, the transverse sliding plate 2d is not affected in the process of processing, namely, on the basis of ensuring the time spent in batch processing, the transverse moving mechanism 2 is prevented from being subjected to larger transverse force, and the precision of the transverse moving mechanism 2 is ensured;
when the jacking mechanism 6 pushes the gear 7 to be processed to move to the top final position, the inserting column 2c is pulled out from the second through hole, the bottom of the inserting column 2c is coplanar with the top of the second through hole, and after the hob 1a is separated from the gear 7 to be processed, the transverse sliding plate 2d is pulled out through the inserting column 2c, and can move transversely when being pushed by the longitudinal pushing mechanism 3.
When the longitudinal pushing mechanism 3 pushes to the final position, if the gear 7 to be processed collides with the hob 1a, the post 2c will be dislocated from the second through hole, which will prevent the post 2c from descending. In this way, the initial frictional contact amount is small after the grooving contact between the gear 7 to be machined and the hob 1a, and the elastic thrust force of the elastic return mechanism 2a can support the thrust force between the gear 7 to be machined and the hob 1a thereat. Wherein the lifting mechanism 6 will descend when the longitudinal pushing mechanism 3 is pushed to the final position. When the plunger 2c is coaxial with the second through hole, the gear 7 to be machined can descend, and the gear 7 to be machined can gradually descend along with continuous friction between the gear 7 to be machined and the hob 1a, so that the plunger 2c slides downwards in the second through hole. In this way, the elastic force of the elastic return mechanism 2a is made small, without causing a large obstruction to the movement of the longitudinal pushing mechanism 3.
In order to realize that the longitudinal pushing mechanism 3 can automatically perform transverse displacement when being pushed longitudinally, the transverse sliding plate 2d can automatically perform transverse displacement. And also for the purpose of the oblique separation and the oblique approaching when the gear 7 to be machined is separated from the hob 1a, the oblique approaching is advantageous in that the initial contact area is further reduced, and the elastic force required for the elastic restoring mechanism 2a is further reduced. And the final position of the oblique approach can be adjusted for different tooth pitches. For this purpose, as shown in fig. 4 to 8, the abutting displacement mechanism 2b includes a first left inclined plate 2b1, a mounting seat and a plurality of precision lifting seats, the mounting seat is fixedly mounted on a horizontal moving table of the gear hobbing machine 1, the plurality of precision lifting seats are adjustable along the length direction of the hob 1a, each precision lifting seat includes an adjusting screw seat 2b4, a right inclined plate 2b2 and two second left inclined plates 2b3 fixedly mounted on the adjusting screw seat 2b4, the right inclined plate 2b2 of each precision lifting seat is inserted between the two second left inclined plates 2b3 of the previous precision lifting seat, the right inclined plate 2b2 at the beginning is inserted between the two first left inclined plates 2b1, one side of the first left inclined plate 2b1 and the second left inclined plate 2b3 close to the contact plate 2e is of an inclined structure, the side of the right inclined plate 2b2 far away from the left inclined plate 1b 1 is of an inclined surface structure, the inclined directions of the right inclined plate 2b2 and the left inclined plate 2b1 and the left inclined plate 2b3 are opposite, when the contact plate 2e is driven by the longitudinal pushing mechanism 3, the contact plate 2e firstly ascends along the inclined surface of the left inclined plate 2b1 or the left inclined plate 2b3 and then slides downwards along the right inclined plate 2b2, and when the contact plate moves to the bottom final position, the gear 7 to be machined is contacted with the hob 1a, and as can be understood, the precision of the gear 7 to be machined is left with errors when being machined last time, and the contact plate 2e is positioned on the inclined surface of the right inclined plate 2b2 and cannot move to the bottommost part.
The overall length of the left inclined plate 1 and the right inclined plate 2b2 determines the distance that the gear 7 to be machined moves along the length direction of the hob 1a. This distance is used to completely move the gear 7 to be machined away from the position in which it was in contact with the hob 1a last machined.
The right inclined plate 2b2 is inserted between the two left inclined plates 2b3, and the position of the precision lifting seat can be adjusted, so that the distance of the gear 7 to be processed along the length direction of the hob 1a can be adjusted adaptively according to different tooth pitches, so that the gear 7 to be processed can be clamped into the hob 1.
As shown in fig. 4, the position when the gear 7 to be processed is notched. Fig. 5 is a state when the gear 7 to be machined is moved outward in the direction of F1, that is, a state in which the contact plate 2e is moved while the left inclined plate 1b 1 or the left inclined plate 2b3 is inclined. Fig. 6 is a state when the gear 7 to be machined moves inward in the direction of F2, that is, a state when the contact plate 2e moves while tilting the right inclined plate 2b 2.
In order to provide elastic restoring force for the transverse sliding plate 2d, as shown in fig. 9, the elastic restoring mechanism 2a includes a collision spring 2a1, a connecting plate 2a2, a guide post 2a3 and a guide plate 2a4, the guide plate 2a4 is fixedly connected with the longitudinal pushing mechanism 3, the connecting plate 2a2 is fixedly connected with the transverse sliding plate 2d, one end of the guide post 2a3 is fixedly connected with the connecting plate 2a2, the guide post 2a3 is slidably connected with the guide plate 2a4, and the collision spring 2a1 is used for providing elastic force for the connecting plate 2a2 far away from the guide plate 2a 4. When the lateral slide 2d is pushed laterally away from the hob 1a, the interference spring 2a1 will be compressed. And when the lateral sliding plate 2d approaches the hob 1a, the lateral sliding plate 2d is made to approach the hob 1a by abutting against the elastic restoring force of the spring 2a 1.
In order to install the jacking mechanism 6 in a smaller space of the gear hobbing machine 1, as shown in fig. 10, the jacking mechanism 6 comprises a double-thread screw rod 6b, a lifting plate 6c, a driving motor 6d and two triangular blocks 6a, an installation groove for installing the double-thread screw rod 6b is formed in the middle of the transverse sliding plate 2d, the two triangular blocks 6a are slidably installed in the installation groove, the double-thread screw rod 6b is meshed with the two triangular blocks 6a, threaded holes meshed with the double-thread screw rod 6b are formed in the triangular blocks 6a, the directions of the two threads on the double-thread screw rod 6b are opposite, inclined surfaces of the two triangular blocks 6a are contacted with the lifting plate 6c, a sliding column is arranged at the bottom of the lifting plate 6c, a sliding hole sliding with the sliding column is formed in the top of the transverse sliding plate 2d, the lifting plate 6c is the lifting seat, the driving motor 6d is fixedly connected with the transverse sliding plate 2d, and the output end of the driving motor 6d is fixedly connected with the double-thread screw rod 6 b. By controlling the driving motor 6d to operate such that the two triangular blocks 6a are simultaneously moved closer to or away from each other, the lifting plate 6c will be lifted up when the triangular blocks 6a are moved closer to each other, and the lifting plate 6c will be lowered when the two triangular blocks 6a are moved away from each other. When the lifting plate 6c is located at the initial position, the distance between the rotating seat 5 and the hob 1a can be used for installing gears 7 to be machined with all thicknesses. When the lifting plate 6c is lifted to the final position, since the bottom supporting position of the gear 7 to be processed by the rotating base 5 is constant, the gear 7 to be processed with different thicknesses can be processed to the bottommost part of the gear 7 to be processed.
