Description

Technical Field

[0001] This utility model belongs to the field of automated parts processing technology and relates to a feeding tray device with adjustable diameter. Background Technology

[0002] Currently, robots are widely used in the gear reduction and manufacturing industry, greatly improving automation levels and product quality. However, the automated feeding devices for gear lathes, which are designed to support these robots, have lagged behind in development. Most domestic factories currently rely on manual labor to feed the gears to the lathes and start processing, resulting in high labor intensity and low efficiency. Automated processing of disc-shaped cylindrical gears is difficult and costly. Significant differences in centering positions during spindle gripping of the gears can lead to clamping misalignment, causing batch scrap during mass production. Furthermore, gear misalignment can cause collisions with the lathe, posing safety hazards. This results in equipment downtime, impacts order delivery, and wasted production costs. Manufacturing a separate tray for each workpiece would significantly increase costs for small-batch, multi-variety processing and also require substantial storage space. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to reduce processing costs and improve processing efficiency for small-batch, multi-variety disc-shaped cylindrical gear processing, and to provide a feeding disc device with an adjustable diameter.

[0017] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 , Figure 2As shown, an adjustable diameter feeding tray device includes a fixed support plate 2, a spiral grooved plate 3 disposed below the support plate 2, the spiral grooved plate 3 being rotatably disposed relative to the support plate 2; at least one arc-shaped groove 31 is disposed on the spiral grooved plate 3, a straight sliding groove 21 is disposed radially on the support plate 2, a slider 4 is slidably disposed within the straight sliding groove 21, and the slider 4 is also slidably disposed within the arc-shaped groove 31; a feeding claw 6 is fixedly disposed above the slider 4.

[0021] Furthermore, the arc-shaped grooves 31 and the straight grooves 21 are correspondingly arranged. There are two, three, four or even more straight grooves 21 arranged radially on the support plate 2. Correspondingly, there are two, three, four or even more arc-shaped grooves 31 arranged on the spiral groove plate 3. In the figure, there are three straight grooves 21 arranged on the support plate 2 and three arc-shaped grooves 31 arranged on the spiral groove plate 3. A slider 4 is slidably arranged on each straight groove 21, and a feeding claw 6 is arranged on each slider 4. In this way, a total of three feeding claws 6 are arranged, and the three together clamp a disc-shaped cylindrical gear.

[0022] Even better, a pin 41 is fixedly provided below each slider 4. The pin 41 is simultaneously slidably provided in the straight groove 21 and the arc groove 31, so that the slider 4 slides between the support plate 2 and the spiral groove plate 3.

[0023] Furthermore, a fastening device is provided between the support plate 2 and the spiral grooved plate 3. The fastening device is a locking bolt 7 provided between the support plate 2 and the spiral grooved plate 3. The locking bolt 7 is used to fix the spiral grooved plate 3 and prevent the spiral grooved plate 3 from rotating.

[0024] Furthermore, the support plate 2 is set on the base 1, which is used to carry materials and convey them on the conveyor belt. Specifically, the support plate 2 is fixed to the base 1 by bolts and pins 8, and the spiral grooved plate 3 rotates on the bolts and pins 8.

[0025] Furthermore, at least one scale 5 is provided on the support plate 2. The scale 5 is fixed to the support plate 2 by bolts and is located on one side of the linear slide 21.

[0026] Furthermore, the feeding claw 6 is fixed to the slider 4 by a pin, which serves to support and position the disc-like cylindrical gear.

[0027] Furthermore, slider 4 can be an integrated feeding slider or a separate feeding slider.

[0028] The working principle of this utility model is as follows:

[0029] During initial debugging, loosen the locking bolt 7 between the support plate 2 and the spiral groove plate 3, and manually rotate the spiral groove plate 3. The arc groove 31 on it will also rotate, forcing the pin 41 to move. Since the pin 41 is also confined within the straight slide groove 21, the slider 4 moves radially within the straight slide groove 21 under the action of the pin 41, thereby adjusting the position of the feeding claw 6. After adjustment, the three feeding claws 6 together clamp a disc-shaped cylindrical gear. After adjustment, tighten the locking bolt 7 to prevent the support plate 2 and the spiral groove plate 3 from rotating relative to each other, thus ensuring that the slider 4 does not move during operation.

[0030] When processing the next batch of disc-shaped cylindrical gears, adjustments will be made again based on the actual diameter.

[0031] Therefore, the adjustable-diameter feeding tray device provided by this utility model can achieve automatic docking with the robot, material channel, and spindle. The entire material handling process of the machine tool is as follows: after the robot picks up the disc-shaped cylindrical gear, it places it on the feeding claw 6, and the conveyor belt transfers the entire tray to the feeding position. The sensor detects that there is a workpiece on the feeding tray, and after the PLC signal is transmitted, the spindle moves to the feeding position to automatically clamp, and then the workpiece is brought to the machining area to start processing.

[0032] The adjustable-diameter feeding tray device boasts high compatibility, reducing labor intensity, improving processing efficiency, and lowering material costs. It is highly adaptable to the production characteristics of passenger car cylindrical gear processing, which involves diverse varieties, small batches, and frequent production changes. Specific benefits include:

[0033] 1. This utility model employs a clamping centering device to achieve repeatability, accuracy, and reliability in automatic material feeding to machine tools. It replaces manual loading and unloading, reducing labor intensity, improving processing efficiency, and lowering material costs.

[0034] 2. The diameter direction of this utility model can be quickly adjusted. By adjusting the angular direction of the spiral groove disk, it can be compatible with the positioning of all series of disc-type cylindrical gears, greatly reducing production changeovers.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
