Description

An automatic feeding device Technical Field

[0001] This utility model relates to the field of cross shaft machining technology, specifically an automatic feeding device. Background Technology

[0002] Cross shafts are crucial components in automobiles and other power systems. Their production typically involves casting followed by grinding, trimming, and end machining. These multiple processes require different machine tools and workstations, necessitating seamless integration to facilitate workpiece turnover and automate the production line. Differences in height between machine tools are common. Current technologies often use ramps or manual transfer to move workpieces to other workstations. However, cross shafts, with their four ends and central block, require different machining directions at different locations. Using ramps for transfer can lead to uncontrollable directional movement during the descent, preventing smooth entry to the next workstation and necessitating repositioning. This results in slow and cumbersome transfer processes.

[0003] Based on this, the present invention designs an automatic feeding device to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic feeding device to solve the problem mentioned in the background art that the direction of the cross shaft workpiece is uncontrollable during the transportation of the transfer parts, requiring the workpiece to be repositioned, resulting in slow transfer efficiency and a complicated process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a connecting plate, a curved slide, and an inlet plate, wherein the curved slide connects the connecting plate and the inlet plate vertically;

[0006] The curved slide includes four curved limiting plates, each of which includes a vertical section, a curved section, and an inlet section. The gaps between the limiting plates allow the workpiece to pass through.

[0007] The vertical section of the limiting strip is used to vertically support the unloading of the connecting plate, the curved section is used to generate friction through lateral displacement to slow down the falling of the workpiece, and the guide section is used to make the workpiece fall horizontally onto the guide plate.

[0008] The end of the connecting plate is provided with a cross groove, which is used to guide the workpiece into the curved slide in a specific shape.

[0009] As a further embodiment of this utility model, the inner edges of the limiting strip are all provided with arc-shaped chamfers and the surface is formed with an anti-scratch layer, which can be a rubber coating.

[0010] As a further embodiment of this utility model, a mounting base is fixedly connected to the bottom of the curved slide, and the mounting base is bolted to the guide plate.

[0011] As a further embodiment of this utility model, the front end of the guide plate is inclined downward and the end is provided with a material dropping groove, the material dropping groove is matched with the shape of the workpiece, and a surrounding edge is fixedly connected to the top side of the guide plate.

[0012] As a further embodiment of this utility model, both the mounting base and the rear end of the guide plate are open, and a push plate is slidably provided between the mounting base and the guide plate, the push plate being used to push the workpiece out of the guide plate.

[0013] As a further embodiment of this utility model, the push plate can be pushed by a cylinder, and the movable rod of the cylinder is fixedly connected to the push plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Under the constraint of the curved slide, it slides into the guide plate in a specific shape, so that the cross shaft part lands smoothly on the guide plate without bouncing, thus avoiding the cross shaft part from changing its orientation.

[0016] It can solve the problem of transferring workpieces with height differences between front and rear workstations, better connect the front and rear workstations, and eliminate the need for re-sorting the material after transfer. At the same time, compared with the traditional method of adding shock-absorbing pads in the inlet plate, it can transfer workpieces more smoothly, with curved directional transfer, which restricts the orientation of the workpiece and reduces the collision of the workpiece during the transfer process.

[0025] Please refer to Figures 1-6. The working principle of the technical solution provided by this utility model is as follows:

[0026] When in use, the device connects the cross shaft with the shaped part via the connecting plate 1 and transports it forward into the cross groove 4, where it falls into the curved slide 2. Under the constraint of the curved slide 2, it slides into the guide plate 3 in a specific shape, so that the cross shaft falls smoothly onto the guide plate 3 without bouncing, thus preventing the cross shaft from changing its orientation.

[0027] Specifically, when sliding down within the curved slide 2, the block portion of the cross shaft is located within the space between all the limiting plates 21, and the shaft of the cross shaft is located within the space between adjacent limiting plates 21 and extends outwards. Thus, the four limiting plates 21 restrict the cross shaft workpiece to slide down in a specific orientation. Since the limiting plates 21 are curved, the lateral friction generated during the cross shaft's descent can both slow it down and change its tendency during descent. As a result, when the cross shaft lands on the guide plate 3, its speed is already low. At the same time, one side of the cross shaft lands first, followed by the entire workpiece, making the landing more stable. This avoids the entire workpiece crashing to the ground and prevents it from bouncing after landing and changing its orientation, providing a good foundation for subsequent conveying.

[0028] The vertical section 201 of the limiting strip 21 can vertically support the connecting plate 1 for unloading, so that the workpiece enters the curved slide 2 in a horizontal state at the bottom, avoiding excessive angle flipping. The curved section 202 is used to generate friction through lateral displacement to slow down the workpiece falling, and plays the role of decelerating and adjusting the workpiece to be slightly tilted. The guide section 203 makes the workpiece fall while maintaining the state of the curved section 202, and then the workpiece is placed horizontally and stably on the guide plate 3 in a specific shape.

[0029] This conveying method solves the problem of transferring workpieces with height differences between front and rear workstations, better connecting the two stations, eliminating the need for re-sorting after conveying, and providing smoother workpiece conveying compared to the traditional method of adding shock-absorbing pads inside the inlet plate 3. It also eliminates the need to consider replacing the shock-absorbing pads. The curved directional conveying method restricts the orientation of the workpiece while reducing collisions during the conveying process. Example

[0030] The cross-shaped workpiece falling onto the guide plate 3 can automatically slide down the inclined guide plate 3 and fall into the processing area of ​​the next station through the end drop groove 6. It can then be conveyed in the adjusted orientation for direct processing, greatly saving intermediate steps and material handling time. Example

[0031] After the workpiece falls onto the guide plate 3, the cylinder 10 is activated, causing the movable rod 9 to extend and drive the push plate 8 to push the workpiece out. Various connecting parts can then be connected to the front end of the guide plate 3 to achieve the connection of multiple workstations and meet processing requirements.

[0032] The inner side of the limiting strip 21 is provided with an arc-shaped chamfer to avoid scratches during the conveying process as much as possible. It is coated with an anti-scratch layer to enhance the protective effect and increase friction, resulting in a better deceleration effect.
