Description

Technical Field

[0001] This utility model relates to the field of passive disk processing feeding technology, and more specifically, to a feeding device for passive disk brazing. Background Technology

[0002] The driven disc plays a crucial role in the transmission system. Working in conjunction with the driving disc, it transmits power, ensuring the proper functioning of the machinery. In chainsaws and lawnmowers, the driven and driving discs interact to transfer engine power to the saw chain or blades, thus achieving the cutting function.

[0003] Currently, before the press-fitting and brazing process of the driven disk, a combination process of the pinion and the driven disk surface is required. During the combination, the pinion and the driven disk surface need to be placed in the placement cylinder one after the other. The placement cylinder has a placement slot for placing the pinion, and the inner diameter of the placement cylinder is the same as the diameter of the driven disk surface. At present, the pinion and the driven disk surface are transported by different conveyor lines and cannot be transferred in groups, so the feeding and conveying efficiency needs to be improved. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a feeding device for passive disc brazing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A passive disc brazing feeding device includes a first chain conveyor belt, a second chain conveyor belt, and placement cylinders. The placement cylinders are disposed on the chain plates of the second chain conveyor belt and are evenly distributed. The device also includes a placement box, a circular groove, a positioning roller, a fixed platform, a deflection assembly, a mounting plate, a dual-axis motion assembly, a servo motor, a connecting rod, a first parallel gripper, and a second parallel gripper.

[0007] Several placement boxes are set on the chain plate of the first chain plate conveyor belt and are distributed at equal intervals, and each placement box corresponds to a placement cylinder;

[0008] Each placement box is equipped with a circular groove and a positioning roller;

[0009] The fixed platform is located on one side of the end area of ​​the first chain conveyor belt;

[0010] The deflection assembly is mounted on a fixed platform and connected to a mounting plate so that the mounting plate can move above the fixed area of ​​the first chain conveyor belt or the second chain conveyor belt and be parallel to the conveying direction of the first chain conveyor belt or the second chain conveyor belt.

[0011] The dual-axis motion assembly is mounted on the mounting plate and is connected to a servo motor.

[0012] The connecting rod is connected to a servo motor;

[0013] The first parallel gripper and the second parallel gripper are respectively located at the bottom and one side of the connecting rod, and the two are distributed at right angles.

[0014] Furthermore, the deflection assembly includes a connecting roller and a drive assembly. One end of the connecting roller is rotatably connected to the fixed platform, and the other end of the connecting roller is connected to a mounting plate. The connecting roller is connected to the drive assembly fixed on the fixed platform, and the drive assembly uses gear transmission.

[0015] Furthermore, the dual-axis motion assembly includes a lead screw assembly, a telescopic component, and a mounting block. The lead screw assembly is mounted on the mounting plate, the telescopic component is mounted on the lead screw assembly and connected to the mounting block, and a servo motor is mounted on the mounting block.

[0016] The above solution, through the deflection component, the dual-axis motion component, and two parallel grippers, can automatically transfer and feed materials into the same placement cylinder after the stable clamping of a set of pinions and the driven disk surface is completed.

[0017] Furthermore, both the first and second parallel grippers have rubber layers on their gripping arms.

[0018] The above solution reduces the probability of wear on the surface of parts when the parallel grippers hold them by means of a rubber layer.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Compared to existing technologies, this device can simultaneously transfer the pinion and driven disk surfaces as a whole through the same conveyor line. Once transferred to a fixed area, the conveyor line stops, and then the pinion and driven disk surfaces are automatically clamped one after the other. Subsequently, the pinion and driven disk surfaces are automatically fed into the same placement cylinder to prepare for subsequent pressing, brazing, and other production processes. The combined feeding and conveying process is more efficient. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 3 As shown, a passive disc brazing feeding device includes a first chain conveyor belt 1, a second chain conveyor belt 16, and a placement cylinder 17. The placement cylinder 17 is disposed on the chain plate of the second chain conveyor belt 16 and is equidistantly distributed. It also includes a placement box 2, a circular groove 3, a positioning roller 4, a fixed platform 5, a deflection assembly, a mounting plate 8, a dual-axis motion assembly, a servo motor 12, a connecting rod 13, a first parallel gripper 14, and a second parallel gripper 15.

[0028] Several placement boxes 2 are arranged on the chain plate of the first chain plate conveyor belt 1 and are distributed at equal intervals, and the placement boxes 2 correspond one-to-one with the placement cylinders 17;

[0029] Each placement box 2 is equipped with a circular groove 3 and a positioning roller 4;

[0030] The fixed platform 5 is located on one side of the end area of ​​the first chain conveyor belt 1;

[0031] The deflection assembly is mounted on the fixed platform 5 and is connected to the mounting plate 8 so that the mounting plate 8 can move above the fixed area of ​​the first chain conveyor belt 1 or the second chain conveyor belt 16 and be parallel to the conveying direction of the first chain conveyor belt 1 or the second chain conveyor belt 16.

[0032] The dual-axis motion assembly is mounted on the mounting plate 8 and is connected to a servo motor 12.

[0033] The connecting rod 13 is connected to the servo motor 12;

[0034] The first parallel gripper 14 and the second parallel gripper 15 are respectively located at the bottom and one side of the connecting rod 13 and are distributed at right angles (for further optimization, the gripping arms of the first parallel gripper 14 and the second parallel gripper 15 are provided with a rubber layer, which can reduce the probability of surface wear of the parts when the parallel grippers hold the parts).

[0035] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the deflection assembly includes a connecting roller 6 and a drive assembly 7. One end of the connecting roller 6 is rotatably connected to the fixed platform 5 via a bearing, and the other end of the connecting roller 6 is connected to a mounting plate 8. The connecting roller 6 is connected to the drive assembly 7 fixed on the fixed platform 5. The drive assembly 7 uses gear transmission. Gear transmission is existing technology and its principle will not be described.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 2 and Figure 3 As shown, the dual-axis motion assembly includes a lead screw assembly 9, a telescopic component 10, and a mounting block 11. The lead screw assembly 9 is mounted on the mounting plate 8, the telescopic component 10 is mounted on the lead screw assembly 9 and the telescopic component 10 is connected to the mounting block 11, and the mounting block 11 is mounted on the mounting block 11. The lead screw assembly is existing technology and its principle will not be described.

[0037] It should be noted that the first chain conveyor belt 1, the second chain conveyor belt 16, the drive assembly 7, the lead screw assembly 9, the telescopic component 10, the servo motor 12, the first parallel gripper 14, and the second parallel gripper 15 are all electrically connected to the controller, which is not shown in the figure.

[0038] The working process of this utility model is as follows:

[0039] First, a small gear and a driven disc are placed in the circular groove 3 and the positioning roller 4 in the box 2 at the initial end of the first chain conveyor belt 1 (the small gear and the driven disc are not shown in the figure). After placement, the center hole of the small gear passes through the positioning roller 4 and is higher than the positioning roller 4. The driven disc is in the circular groove 3 and is higher than the height of the circular groove 3. The diameter of the circular groove 3 is matched with the diameter of the driven disc.

[0040] The controller then controls the two chain conveyor belts to start and stop synchronously and intermittently. After the first placement box 2 is conveyed forward, the next empty placement box 2 can move to the same feeding area again. Then the above process is repeated to place the small gear and the driven plate in the remaining placement boxes 2 in sequence. When the first placement box 2 with the parts placed moves to the end area of ​​the first chain conveyor belt 1, it stops.

[0041] In the initial state, the mounting plate 8 moves accurately to the top of the first chain conveyor belt 1 and is parallel to its chain under the action of the deflection component. At the same time, the first parallel gripper 14 is exactly above the pinion (the initial controller controls the dual-axis motion component to complete the positioning). Then the telescopic component 10 drives the first parallel gripper 14 to descend to a preset height, which can then clamp the pinion. After clamping, the telescopic component 10 moves up, which can then disengage the pinion from the positioning roller 4 to complete the clamping and transfer.

[0042] Then, through a pre-set program, the servo motor 12 can rotate at a fixed angle to complete the position change of the two parallel grippers. At this time, the second parallel gripper 15 moves to the original position of the first parallel gripper 14 (as shown in the instruction manual). Figure 3 (as shown in the diagram), the controller then controls the lead screw assembly 9 to work so that the second parallel gripper 15 moves to the top of the passive disk surface according to the pre-set program. Then the controller controls the telescopic component 10 to move again and cooperate with the second parallel gripper 15 so that the passive disk surface can be disengaged from the circular groove 3 to achieve clamping and transfer.

[0043] After the pinion gears and the driven disk are clamped sequentially, the controller controls the drive assembly 7 to operate, thereby causing the mounting plate 8 to rotate 180 degrees. (During the rotation, the controller controls the servo motor 12 to operate again, thereby causing the first parallel gripper 14 to return to its initial state, as shown in the instruction manual.) Figure 2 As shown in the diagram, after the movement is completed, the first parallel gripper 14 is controlled to move horizontally to the top of the placement cylinder 17 according to the pre-set program (the placement cylinder 17 and the placement box 2 correspond one-to-one and move synchronously). Then, the pinion is placed in the placement slot in the placement cylinder 17 and the clamping is released. After the pinion is placed, the first parallel gripper 14 moves away from the placement cylinder 17 under the drive of the telescopic component 10. Then, the controller controls the servo motor 12 to work, and the second parallel gripper 15 and the first parallel gripper 14 exchange positions. Then, the passive disk surface can also be placed in the same placement cylinder 17. After placement, the passive disk surface is higher than the placement cylinder 17 (the second parallel gripper 15 clamps the upper area when clamping the passive disk surface). At this time, the combination of the pinion and the passive disk surface can be automatically completed in preparation for the subsequent press-fitting and brazing process. Then, the controller controls the drive component 7 to work to reset the mounting plate 8. After the mounting plate 8 is reset (as shown in the instruction manual), Figure 1 (as shown in the diagram), and then the two chain conveyor belts will restart synchronously to begin a new round of combination processes;

[0044] Compared to existing technologies, this device can simultaneously transfer the pinion and the driven disk surface through the same conveyor line. Once transferred to a fixed area, the conveyor line stops, and then the pinion and the driven disk surface are automatically clamped one after the other. Subsequently, the pinion and the driven disk surface are automatically fed into the same placement cylinder 17 to prepare for subsequent pressing, brazing and other production processes. The feeding and conveying effect of the two combined process is better.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
