Description

Technical Field

[0001] This utility model relates to the field of ball cage production and testing technology, and relates to a short rod moving joint angle positioning device. Background Technology

[0002] As a key component in automotive transmission systems and precision mechanical transmission mechanisms, the short-bar ball joint cage has a structure containing precision internal channels. Subsequent processing (such as laser marking, internal channel inspection, and assembly adaptation) requires precise positioning as a prerequisite. Positioning accuracy directly affects the workpiece processing quality and assembly compatibility. Therefore, the stability, accuracy, and automation of its motion positioning equipment are required to be high.

[0003] The traditional positioning device only has a single positioning function. After positioning, the short rod ball cage needs to be manually moved to the next process (such as marking or testing). This not only increases the time spent on transportation, but also makes it easy for the workpiece surface to be scratched or the inner groove to be deformed due to manual operation. In addition, there are many manual intervention links, which may lead to equipment collisions or personnel safety risks due to operational errors. This does not meet the requirements of "high efficiency, low loss and safety" in modern industrial production. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solution: A short rod moving joint angle positioning device, comprising: a hopper, a transport mechanism, and a positioning mechanism. The transport mechanism includes a transport frame that is connected to the hopper and a transport chain plate rotatably mounted on the transport frame. The positioning mechanism includes a pushing module and a positioning module. The pushing module includes a pushing cylinder one and a pushing cylinder two symmetrically arranged on both sides of the transport frame. The positioning module includes a mounting plate disposed on the side end of the transport frame, a lifting cylinder disposed on the mounting plate, a rotating cylinder disposed at the end of the piston rod of the lifting cylinder, and a positioning core seat disposed on the rotating cylinder.

[0006] In a further improvement, a pusher plate is provided at the end of the piston rod of the first pusher cylinder, and a pusher plate is provided at the end of the piston rod of the second pusher cylinder. The cross-section of the pusher plate is U-shaped, and the positioning core seat is slidably and vertically arranged inside the pusher plate.

[0007] As a further improvement, the pusher plate II has a chamfer on the side near the conveyor frame.

Detailed Implementation

[0013] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "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.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0016] Example 1 A short rod moving joint angle positioning device includes: a hopper 1, a transport mechanism 2, and a positioning mechanism 3. The transport mechanism 2 includes a transport frame 21 that is connected to the hopper 1 and a transport chain plate 22 rotatably mounted on the transport frame 21. The positioning mechanism 3 includes a pushing module 31 and a positioning module 32. The pushing module 31 includes a pushing cylinder 311 and a pushing cylinder 312 symmetrically arranged on both sides of the transport frame 21. The positioning module 32 includes a mounting plate 321 disposed on the side end of the transport frame 21, a lifting cylinder 322 disposed on the mounting plate 321, a rotating cylinder 323 disposed at the end of the piston rod of the lifting cylinder 322, and a positioning core seat 324 disposed on the rotating cylinder 323. The positioning core seat 324 is disposed corresponding to the inner groove of the short rod ball cage.

[0017] like Figures 1-4As shown, in the process of using this utility model, firstly, the transport mechanism 2 is started, and the short rod ball cage to be positioned in the hopper 1 is transported to the corresponding work position of the positioning mechanism 3 by the rotating transport chain plate 22 on the transport frame 21. At this time, the work position sensor triggers to generate an electrical signal, and the transport chain plate 22 stops operating. Secondly, the piston rod of the pushing cylinder 311 extends, pushing the short rod ball cage located on the transport chain plate 22 into the upper end of the positioning module 32. After being pushed into place, the piston rod of the pushing cylinder 311 retracts and resets. Thirdly, the piston rod of the lifting cylinder 322 extends, driving the rotating cylinder 323 to move upward, so that the positioning core seat 324 fixed at the rotating end of the rotating cylinder 323 gradually approaches the bottom of the short rod ball cage. At the same time, the rotating cylinder 323 starts synchronously, driving the positioning core seat 324 to rise. During the process, the cylinder rotates slowly. Due to the pre-designed corresponding structure between the positioning core seat 324 and the inner groove of the short rod ball cage, the positioning core seat 324 aligns with the inner groove of the short rod ball cage during rotation, allowing the positioning core seat 324 to be inserted into the short rod ball cage, thus achieving initial fixation of the short rod ball cage. After the positioning core seat 324 securely engages with the short rod ball cage, the rotary cylinder 323 rotates again according to the preset positioning requirements. The positioning core seat 324 drives the short rod ball cage to rotate to the angle required by the process, completing the angle positioning. Finally, the piston rod of the second pusher cylinder 312 of the pusher module 31 extends, pushing the positioned short rod ball cage back onto the transport chain plate 22. The piston rod of the second pusher cylinder 312 then retracts, and the transport chain plate 22 restarts, transporting the positioned short rod ball cage to the next processing step.

[0018] This utility model device automatically transports the short rod ball cage in the hopper to the positioning station via the transport chain plate. With the trigger action of the station sensor, the pushing cylinder, lifting cylinder and rotating cylinder operate automatically according to the preset process, eliminating the need for manual handling and alignment, greatly reducing manual intervention, lowering labor costs, and avoiding efficiency fluctuations and errors in manual operation.

[0019] As a further preferred embodiment, the piston rod end of the first pushing cylinder 311 is provided with a first pushing plate 3111, and the piston rod end of the second pushing cylinder 312 is provided with a second pushing plate 3121. The second pushing plate 3121 has a U-shaped cross section, and the positioning core seat 324 is slidably and vertically disposed within the second pushing plate 3121.

[0020] Specifically, when the piston rod of the pusher cylinder 311 extends, the pusher plate 3111 contacts the end face of the short rod ball cage through the V-shaped contact point to prevent the short rod ball cage from deviating during the pushing process; at the same time, the two side groove walls of the U-shaped structure of the pusher plate 3121 form a lateral limit on the short rod ball cage, further preventing the short rod ball cage from deviating during the pushing process.

[0021] As a further preferred embodiment, the pusher plate 3121 is provided with a chamfer 31211 on the side near the transport frame 21.

[0022] Specifically, a smooth transition slope is formed by chamfering 31211 to avoid interference when pushing the short stick into the cage.

[0023] As a further preferred embodiment, the hopper 1 includes a hopper frame 11 and a feeding chain plate 12 rotatably disposed within the hopper frame 11. At least two sets of the feeding chain plates 12 are horizontally arranged, and guide plates 13 are respectively provided on the upper sides of the two adjacent sets of feeding chain plates 12.

[0024] Specifically, step-by-step transportation is achieved through at least two sets of feed chain plates 12 that turn in opposite directions. The short rod ball cage is first transported to the guide plate 13 by one set of feed chain plates 12, and then slides to the adjacent chain plate running in the opposite direction. The feeding speed and interval of the short rod ball cage can be controlled in an orderly manner, avoiding the problem of workpieces piling up and blocking the transportation mechanism 2 when batch feeding occurs, and ensuring that the feeding rhythm is accurately matched with the subsequent transportation and positioning processes.

[0025] As a further preferred embodiment, it also includes a laser marking mechanism 4, the working end of which is disposed on the upper end of the positioning module 32.

[0026] Specifically, the laser marking mechanism can be linked with the positioning module and the transport mechanism: after the positioning module fixes the workpiece angle, it automatically triggers the laser marking mechanism to start; after marking is completed, the positioning module releases the workpiece, which is then pushed to the transport chain by the pushing mechanism. The entire process does not require manual adjustment of the marking position or starting and stopping of the equipment, reducing manual operation errors, lowering labor costs, and improving the safety and stability of the production process.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
