Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a rotary positioning device for parts with complex geometric shapes. Background Technology

[0002] For parts forming, the current conventional production structure uses a vibratory feeder and a feeding track to control the feeding direction. For simple-shaped parts, such as round or square products with symmetrical contours, the positioning of the product direction controlled by the vibratory feeder and feeding track is sufficient. However, for products with complex shapes and high positioning requirements, the above method is not suitable because the positioning accuracy of the vibratory feeder's outlet is not very high. For example, when using a feeding track to position the direction of the toothed or asymmetrical complex geometric parts, the product may rotate, get stuck, detach, or even become completely jammed within the feeding track. This leads to uneven feeding, affects the forming and positioning of subsequent processes, and impacts production speed and debugging / maintenance time. Utility Model Content

[0003] The purpose of this invention is to provide a rotary positioning device that can rotate and position complex geometric parts at the discharge port and before forming to control the orientation of the parts.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A rotary positioning device for complex geometric parts includes a rotary positioning mechanism, which is located at the discharge port of the unloading track. A robot arm clamps the parts on the unloading track and places them onto the rotary positioning mechanism to achieve rotary positioning of the parts.

[0006] Preferably, the rotary positioning mechanism includes a rotating mechanism and a toggle mechanism, with the toggle mechanism located above the rotating mechanism;

[0007] The actuating mechanism is mounted on a mounting plate, and the mounting plate is connected to the base via a first support plate.

[0008] The rotating mechanism is mounted on a support plate, and the support plate is connected to the mounting plate via a column.

[0009] Preferably, a cylinder for driving the rotation mechanism is provided on one side of the rotation mechanism, the cylinder is fixed on the second support plate, and the second support plate is connected to the base.

[0010] Preferably, the rotating mechanism includes a gear and a rack, the gear being connected to a connecting seat via a gear shaft, and the connecting seat being located below the actuating mechanism;

[0011] The rack is connected to the cylinder via a push rod.

[0012] Preferably, a rack support plate is provided on one side of the rack to support the rack, and the rack support plate is mounted on the support plate.

[0013] Preferably, the actuating mechanism includes an actuating disc and a paddle for changing the position of the actuating component;

[0014] The side of the dial is mounted on the mounting plate by screws, and the bottom of the dial is located on the connecting seat;

[0015] The lever is mounted on the connector.

[0016] Preferably, a part actuation groove is provided on the actuation disk.

[0017] The beneficial effects of this utility model are:

[0018] (1) The present invention proposes a rotary positioning device for complex geometric parts. By setting a rotary positioning mechanism at the discharge port of the feeding track, the robot arm clamps the parts on the feeding track and places them on the rotary positioning mechanism to achieve rotary positioning of the parts and improve the accuracy of the parts positioning.

[0019] (2) The rotary positioning mechanism uses a cylinder as a power source. The cylinder's extension and retraction motion drives the entire rotary positioning mechanism. The cylinder pushes the rack meshing with the gear to move linearly, thereby driving the gear to rotate. The gear shaft also rotates with the gear. The paddle on the upper end of the gear shaft rotates accordingly. The paddle contacts the part and rotates to position the product correctly, thereby achieving precise positioning of the product.

[0020] (3) The rotary positioning device for complex geometric parts proposed in this utility model has a simple and clear structure and is easy to operate. It can be directly used with existing equipment to realize automated production. Moreover, the positioning rotary device fully considers the positioning requirements of complex shaped parts and combines the precise control of multiple steps such as loading and unloading on existing equipment to ensure product quality and production efficiency. At the same time, the paddle mechanism is a replaceable modular design that can meet the needs of different parts. The modular design also facilitates maintenance and upgrades and can quickly adapt to different production needs. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] In this embodiment, a gear part is used as an example to illustrate how to rotate and position the transported part to adjust its orientation. Since existing vibratory feeder mechanisms can only meet the positioning and transport requirements of some simple-shaped products, and cannot meet the positioning requirements of complex parts, the original feeding and unloading mechanisms are retained, and the rotary positioning mechanism described in this invention is added before the product is formed. After the gear part enters the vibratory feeder through the loading mechanism, it is roughly positioned and transported by the vibratory feeder. When the gear part reaches the vibratory feeder outlet, the part has already been roughly positioned. It is then transported via the unloading track. At this time, the part's positioning within the unloading track is still coarse, so the positioning of the part is still inaccurate when it reaches the rotary positioning mechanism.

[0030] In this embodiment, the gear part 10 enters the vibratory feeder via the feeding mechanism and is transported from the vibratory feeder's outlet to the unloading track. A rotary positioning mechanism is provided at the outlet of the unloading track. The gear part 10 is gripped by a robotic arm and placed into the rotary positioning mechanism for rotational positioning and orientation adjustment. Since the feeding and unloading mechanisms are existing equipment, they are not shown in the accompanying drawings, but this does not affect the understanding and use by those skilled in the art, and therefore will not be described in detail.

[0031] Specifically, such as Figure 1-3 As shown, the rotary positioning mechanism includes a rotating mechanism and a toggle mechanism, with the toggle mechanism located above the rotating mechanism;

[0032] The actuating mechanism is mounted on the mounting plate 11 and can be fixed with screws; the mounting plate 11 is connected to the base 12 through the first support plate 13, and the first support plate 13 can be fixedly mounted on the mounting plate 11 with screws.

[0033] The rotating mechanism is mounted on the support plate 16, which is connected to the mounting plate 11 via columns 15. Four columns can be provided, each fixed at its upper end with screws and at its lower end to the support plate.

[0034] Furthermore, a cylinder 8 for driving the rotation mechanism is provided on one side of the rotation mechanism. The cylinder is mainly used to drive the rotation mechanism to move. The cylinder 8 is fixed on the second support plate 14, and the second support plate 14 is connected to the base 12.

[0035] The rotating mechanism is mainly used to drive the actuating mechanism to rotate, thereby achieving the rotational positioning of the part. For example... Figure 4 , 5 As shown, the rotating mechanism includes a gear 1 and a rack 2. The gear 1 is connected to a connecting seat 4 via a gear shaft 3, and the connecting seat 4 is located below the actuating mechanism. The rack 2 is connected to a cylinder 8 via a push rod 9. Driven by the cylinder, the push rod pushes the rack to move, the rack drives the gear to rotate, and thus drives the actuating mechanism to rotate and position.

[0036] Furthermore, a rack support plate 17 is provided on one side of the rack 2 to support the rack 2, and the rack support plate 17 is mounted on the support plate 16. The rack support plate serves to support the movement of the rack. In this embodiment, the gear 1 and the rack 2 are arranged perpendicular to each other, and the movement of the rack drives the gear to rotate.

[0037] Specifically, in this embodiment, the actuating mechanism includes an actuating disk 5 and a paddle 7 for actuating the position of a part. The side of the actuating disk 5 is mounted on the mounting plate 11 by screws, and the bottom of the actuating disk 5 is located on the connecting seat 4. A part actuation groove 6 is provided on the actuating disk 5. The paddle 7 is disposed on the connecting seat 4, and the paddle plays the role of aligning or positioning the product during rotation. Based on this, the gear is connected to the connecting seat through a gear shaft. The rack and gear cooperate, and when the gear rotates, the gear shaft also rotates. The upper end of the gear shaft is connected to the connecting seat. The rotation of the gear shaft drives the connecting seat to rotate, thereby driving the actuating mechanism to rotate and position the part. Moreover, the paddle is disposed on the connecting seat, and the rotation of the connecting seat drives the paddle to rotate simultaneously. The gear part picked up by the robotic arm is placed on the rotating mechanism. The paddle cooperates with the part actuation groove, and the paddle can actuate the gear part in the part actuation groove to achieve rotational positioning of the gear part, improve the positioning accuracy of the part, and facilitate the positioning of the part in subsequent forming processes.

[0038] Working principle: The gear part 8 is gripped by the robotic arm and put into the actuation mechanism. The cylinder 8 pushes the rack 2 to drive the gear 1, the gear 1 drives the gear shaft 3 to rotate, the gear shaft 3 drives the connecting seat 4 to rotate, the actuation plate 6 is located on the connecting seat 4, and the actuation plate 7 actuates the part on the actuation groove 6 to make the part rotate and position to the final correct direction. After positioning is completed, the mechanical gripper grabs the part again and transfers it to the next process.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
