The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
This high strength wheel hub's intelligent transfer chain is including the clamping device who is used for the fixed wheel hub original paper of centre gripping and possess the conveyor who makes a round trip to transport clamping device function.
The conveying device is herein explained as a device with a function of conveying articles, the design of which can be referred to in the prior art as an article conveying line conveying device in a workshop, and the conveying process can be intelligently controlled by a PLC controller to a conveying position, a stagnation position and the like, and the detailed discussion is not developed herein because this part is a mature and easily realized design element.
As shown in fig. 1 to 4, the clamping device comprises a clamping shaft 1, a clamping ring 2, an adjusting block 3, a circular adjusting rod 4 and a plurality of groups of jaw components which are arranged on the clamping shaft 1 in a central symmetry manner, wherein the clamping ring 2 is fixedly sleeved at the tail end of the clamping shaft 1, the transverse section of the adjusting block 3 is in a regular polygon shape (for example, in the embodiment, four groups of jaw components are distributed in a cross-shaped central symmetry manner, the regular polygon is a square shape), a through hole 5 with the transverse section identical to that of the adjusting block 3 is formed in the center of the front end surface of the clamping shaft 1, the adjusting block 3 is slidably arranged in the through hole 5, a shaft hole is formed in the center of the rear end surface of the clamping shaft 1, the shaft hole is communicated with the through hole 5, the circular adjusting rod 4 is rotatably arranged in the shaft hole and can only perform rotary motion relative to the clamping shaft 1, a screw hole 6 is formed in the center of the adjusting block 3, the outer ring of the front end of the circular adjusting rod 4 is provided with threads, the screw hole 6 is matched in the screw hole 6 of the adjusting block 3, the circular adjusting rod 4 is rotated and then moves in the through the screw hole 6, the adjusting block 3 moves in the through the screw hole 5, the clamping jaw 8 is provided with the front end of the clamping jaw component, the front end of the clamping rod 1 is provided with the clamping jaw component, the clamping jaw component is provided with the clamping jaw component, and the clamping jaw component is provided with the clamping jaws 7 and has the clamping jaws 8 and the clamping jaw 8.
In use, as shown in fig. 1 and 2, the central hole of the hub is sleeved on the clamping shaft 1 shown in fig. 1 from the left side until the right side surface of the hub is attached to the clamping ring 2, then the circular adjusting rod 4 is rotated, so that the clamping claws 8 in the claw assembly are turned over, and after the clamping claws 8 are turned over, the clamping claws 8 are moved rightward until the clamping claws are attached to the left side surface of the hub, so that the positional relationship shown in fig. 2 is formed.
Because a very firm clamping effect is not required, the clamping jaw 8 only needs to provide a slight supporting force against the hub, so the length of the clamping jaw 8 can be made very small and only needs to be turned over beyond the clamping shaft 1, but the length of the clamping jaw 8 is lengthened in the figures herein for ease of understanding during implementation.
The gripper jaw 8 is to perform two actions under the action of the circular adjustment lever 4: the clamping shaft 1 is turned over from the notch 7 and then moves towards the clamping ring 2 to complete the clamping function. Therefore, the design of the jaw assembly requires certain design requirements.
As shown in fig. 5 to 8, the jaw assembly comprises a rack 9, a gear 10, a retraction block 11, a first spring 12 and a second spring 13, wherein the front end of the retraction block 11 is provided with a containing opening 14 for containing the rack 9, the gear 10 and the jaw 8, two sides of the containing opening 14 of the retraction block 11 are provided with rotating holes, a rotating shaft 15 is transversely and fixedly arranged on the jaw 8, the jaw 8 is rotatably arranged on the rotating holes through the rotating shaft 15, the rack 9 is fixedly arranged on the side surface of the adjusting block 3, the gear 10 is fixedly sleeved on the rotating shaft 15, the gear 10 is meshed with the rack 9, two ends of the first spring 12 are respectively fixed on the end surfaces of the rack 9 and the containing opening 14 of the retraction block 11, two ends of the second spring 13 are respectively fixed on the outer end of the retraction block 11 and the end surface of a notch 7 of the clamping shaft 1, and the elastic potential energy of the second spring 13 is larger than that of the first spring 12;
when the rollback block 11 is in the foremost initial position: the second spring 13 is in a fully sprung state in which the retraction block 11 is (has a tendency to) pushed to the forefront with respect to the clamp shaft 1, the first spring 12 is in a fully sprung state in which the rack 9 is (has a tendency to) pushed to the forefront with respect to the retraction block 11, and in which the gear 10 is located at the rightmost end of the rack 9, the clamp claw 8 being fully buried in the receiving opening 14 of the retraction block 11;
during the movement of the retraction block 11 in the rear end direction: the rack 9 moves backward firstly to drive the gear 10 to rotate so that the clamping claw 8 is gradually lifted up from the accommodating opening 14 to a vertical state, meanwhile, the first spring 12 is extruded to a complete extrusion state, and the rack 9 is provided with conduction power through the first spring 12 in the complete extrusion state to drive the retraction block 11 to move right.
In the above description: the front end is the left end in the illustration and the rear end is the right end in the illustration.
Fig. 5 to 8 illustrate the whole clamping process (the illustrated drawing conceals the clamping shaft 1 in fig. 3), in which an operator rotates the circular adjusting lever 4, and because the adjusting block 3 is limited to the through hole 5, the adjusting block 3 makes a retreating sliding motion (similar to the motion principle of a screw rod sliding block) toward the tail end of the clamping shaft 1 at the through hole 5 under the action of the threaded screw hole 6, in which the adjusting block 3 moves rightward relative to the clamping shaft 1, and then the positional relationship of each part is rearranged into the following information:
adjusting block 3: independently movable relative to the clamping shaft 1, the circular adjusting rod 4 drives the movement in the through hole 5 of the clamping shaft 1;
rollback block 11: independently movable with respect to the clamping shaft 1, the pressure provided by the second spring 13 creates a tendency to move to the left;
gripper jaw 8: the clamping jaw 8 can move in a turnover manner relative to the retraction block 11, but because of the position relation between the gear 10 and the rack 9, the position angle of the clamping jaw 8 relative to the retraction block 11 is completely determined by the position where the gear 10 is matched with the rack 9;
rack 9: the rack 9 is connected with the retraction block 11 through a first spring 12, so that the rack 9 can serve as an intermediate piece to enable the movement of the two independent movable adjustment blocks 3 and the retraction block 11 relative to the clamping shaft 1 to be connected together.
After the position relation of each part is analyzed, the movement process is more easily understood by describing the movement process specifically, and the movement process is as follows:
as shown in fig. 5, when the adjusting block 3 moves to the right and the rack 9 and the adjusting block 3 are fixed with each other, the rack 9 slides to the right, because the elastic potential energy of the second spring 13 is far greater than that of the first spring 12, the second spring 13 still provides a great elastic force to keep the retracting block 11 at the leftmost position all the time, that is, the retracting block 11 can be regarded as fixed, the gripper jaw 8 is rotationally arranged on the retracting block 11, and in the process, the rack 9 moves to the right to turn the gear 10, the gear 10 can be gradually lifted up with the gripper jaw 8, and meanwhile, the first spring 12 is gradually compressed, as shown in fig. 6;
when the first spring 12 is compressed to the fully compressed state, the length of the rightward movement of the rack 9 just turns the gear 10 by 90 °, and the gripper jaw 8 is in the fully erected state perpendicular to the axial direction of the gripper shaft 1, as shown in fig. 7;
the movement of the adjustment block 3 to the right is then continued, since the first spring 12 has been fully compressed, so that the force of the movement of the adjustment block 3 to the right is no longer applied to the first spring 12 to cause it to elastically compress and deform, and the rightward movement of the retraction block 11 is applied to the retraction block 11 by the fully compressed first spring 12 to cause the retraction block 11 to move to the right, while the second spring 13 starts to be compressed and deformed, which is the clamping process of gradually bringing the fully opened clamping jaw 8 towards the hub, as shown in fig. 8.
When the hub is required to be unloaded, the round adjusting rod 4 is reversely rotated, and all parts can be reset in time under the action of the first spring 12 and the second spring 13.
Through the above description, the application convenience of the clamping device is extremely high, and the whole process workers only need two operations: the first is to sleeve the hub on the clamping shaft 1, and the second is to continuously rotate the circular adjusting rod 4 in the same direction, and then directly clamp the hub.
As shown in fig. 1 and 2, the side wall of the notch 7 of the clamping shaft 1 is provided with a limit groove 16, and the side edge of the retraction block 11 is provided with a limit bar, and the limit bar is slidably embedded in the limit groove 16 so that the retraction block 11 cannot be separated from the clamping shaft 1.
In order to improve reliability, the jaw assembly is provided with two gears 10 and two racks 9, the two gears 10 are respectively fixed on rotating shafts 15 on two sides of the clamping jaw 8, and the two racks 9 are respectively meshed with the two gears 10. The rack 9 may also be fixedly connected together by a bottom block, and then the first spring 12 is connected to the bottom block, which is itself an integral piece, so that it corresponds to the first spring 12 directly abutting the rack 9.
The clamping shaft 1 of the outer ring in the middle of the shaft hole is also provided with a ring-shaped groove, the outer ring of the circular adjusting rod 4 is provided with a ring-shaped body, and the ring-shaped body is positioned in the ring-shaped groove so that the circular adjusting rod 4 can only rotate relative to the clamping shaft 1.
The tail end of the circular adjusting rod 4 is provided with a handle 17 which is convenient for an operator to manually rotate. The handle 17 can be rotated during the use process.
A high-strength hub processing technology of an intelligent conveying line adopting the high-strength hub comprises the following steps of: adding an aluminum alloy ingot into a smelting furnace, controlling and stabilizing the temperature to be 850-900 ℃ and continuously smelting the aluminum alloy ingot for more than 30 minutes to obtain aluminum alloy liquid, adding sodium chloride, potassium chloride and sodium carbonate, then carrying out secondary smelting, controlling the secondary smelting temperature to be 660-670 ℃ for more than 5 hours, standing and deslagging, adding sodium fluoroaluminate, then carrying out tertiary smelting, controlling the tertiary smelting temperature to be 540-550 ℃ for more than 1 hour, and finally pouring the aluminum liquid into casting equipment, and cooling and forming to obtain the hub; turning and polishing the hub on a machine tool, clamping the hub by a clamping device, and then conveying the hub into an intelligent conveying line to finish cleaning, drying and detecting processes, wherein a qualified product is a hub finished product.
