Description

Technical Field

[0001] This utility model relates to the field of stop gauge structure technology, and in particular to a multi-degree-of-freedom stop gauge structure. Background Technology

[0002] In the field of automated manufacturing, stop structures, as key components in the material conveying, positioning and sorting process, are widely used in various scenarios such as assembly lines, assembly tables and sorting equipment. Their core function is to use their own structural positioning to block and limit the conveyed materials, correct their posture or separate them in an orderly manner, and provide accurate material posture and position assurance for subsequent processing, assembly and testing processes, which directly affects the operating efficiency of the entire production line and the stability of product quality.

[0003] Currently, most of the gauge structures on the market are traditional fixed structures. Fixed gauges are directly fixed to the equipment frame by bolts and other fasteners. Their position cannot be adjusted according to actual production needs after installation and commissioning. When it is necessary to change materials of different specifications or adjust the production process, the gauge must be disassembled and reinstalled. This is not only cumbersome and time-consuming, but also leads to extended production line downtime, which seriously affects production efficiency. To solve the above problems, this application proposes a multi-degree-of-freedom gauge structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-degree-of-freedom stop structure. This structure uses a power source to drive a lead screw to rotate in conjunction with a guide mechanism, enabling smooth horizontal movement. Simultaneously, a lifting power source drives the actuator to lift vertically. The two work together to precisely adjust the spatial position of the actuator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-degree-of-freedom stop structure includes a first mounting block and a second mounting block located on one side of the first mounting block. A motor is fixedly connected to the end of the first mounting block away from the second mounting block. A coupling is installed at the output end of the motor, and a lead screw is installed at the output end of the coupling. The lead screw passes through the first mounting block and is rotatably connected to it. The end of the lead screw is rotatably connected to the side wall of the second mounting block. A movable plate is threadedly connected to the outer wall of the lead screw. A guide mechanism is provided on the movable plate. A pneumatic rod is fixedly connected to the side wall of the movable plate. A stop element is fixedly connected to the output end of the pneumatic rod. A signal detection frame is fixedly connected to the top of the stop element. An L-shaped plate is fixedly connected to the bottom of the signal detection frame. A signal detector is fixedly connected to the L-shaped plate. Proximity switches are fixedly connected to the opposite ends of the first and second mounting blocks.

[0006] Preferably, the guiding mechanism includes a guide rail that is fixedly connected to both the first mounting block and the second mounting block, and a slider that is slidably connected to the outer wall of the guide rail. The rear end of the moving plate and the front end of the slider are fixedly connected.

[0007] Preferably, the outer wall of the lead screw is provided with an external thread, and the movable plate has a through opening, the inner wall of the through opening being provided with an internal thread that mates with the external thread.

[0008] Preferably, the movable plate and the gas spring are fixed together by multiple bolts.

[0009] Preferably, the signal detection frame has a through hole, which is located directly above the signal detector.

[0010] Preferably, the opposite ends of the first mounting block and the second mounting block are fixed to their corresponding proximity switches by welding.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The power source drives the lead screw to rotate and cooperates with the guide mechanism to achieve smooth horizontal movement. At the same time, the lifting power source drives the actuator to complete the vertical lifting. The two work together to accurately adjust the spatial position of the actuator. Compared with fixed type and single degree of freedom gauge, it can adapt to the positioning requirements of different specifications of materials and different work stations without disassembly and reassembly or auxiliary mechanisms, which greatly shortens the adjustment time and improves the flexibility and efficiency of the production line.

[0012] 2. The cooperation between the guide component and the sliding component provides reliable guidance for horizontal movement, effectively avoiding jamming and shaking during the adjustment process.

[0013] 3. Position detection components are installed at the extreme positions at both ends of the horizontal movement. The movement position of the load-bearing component can be detected in real time and the limit is triggered to prevent it from exceeding the safe travel and colliding with other parts of the equipment, avoiding structural damage or production accidents. This solves the safety hazard of the lack of effective limit in the existing gauge and improves the reliability of equipment operation.

[0014] 4. By integrating signal detection components into the actuators, the actuators can monitor in real time whether they are carrying materials, eliminating the need for separate detection devices. This not only simplifies the overall structure of the equipment and reduces installation space, but also avoids the problems of missed or false detections caused by installation position deviations of independent detection devices. This reduces equipment manufacturing costs and debugging difficulty, and ensures the effectiveness of automated closed-loop control of the production line.

[0015] In summary, by using a power source to drive the lead screw to rotate in conjunction with a guide mechanism, smooth horizontal movement can be achieved. At the same time, by using a lifting power source to drive the actuator to complete vertical lifting, the two work together to precisely adjust the spatial position of the actuator.

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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-2 A multi-degree-of-freedom stop gauge structure includes a first mounting block 1 and a second mounting block 2 located on one side of the first mounting block 1. The first mounting block 1 and the second mounting block 2 provide a mounting support foundation for the overall structure. Both the first mounting block 1 and the second mounting block 2 are fixedly mounted to the external housing. A motor 3 is fixedly connected to the end of the first mounting block 1 away from the second mounting block 2. The motor 3 serves as a power source to provide driving force for the rotation of the lead screw 5. The motor 3 is fixedly mounted to the external housing. A coupling 4 is installed at the output end of the motor 3 for connecting the motor 3. The lead screw 5 transmits rotational power. The output end of the coupling 4 is equipped with the lead screw 5. The lead screw 5 drives the moving plate 6, which is threaded to it, to move linearly by rotating. The lead screw 5 passes through the first mounting block 1 and is rotatably connected to it. The end of the lead screw 5 is rotatably connected to the side wall of the second mounting block 2. The outer wall of the lead screw 5 is fitted with the moving plate 6, which is threaded to it. The moving plate 6 is used to support the air rod 9 and other subsequent components and drive them to move synchronously. The outer wall of the lead screw 5 is provided with external threads. The moving plate 6 has a through opening, and the inner wall of the through opening is provided with internal threads that cooperate with the external threads.

[0020] The movable plate 6 is provided with a guide mechanism, which is used to limit the movement direction of the movable plate 6 so that it moves smoothly. The guide mechanism includes a guide rail 8 that is fixedly connected to the first mounting block 1 and the second mounting block 2. The guide rail 8 cooperates with the slider 7 to provide directional guidance for the movable plate 6. The outer wall of the guide rail 8 is fitted with a slider 7 that is slidably connected to it. The slider 7 is connected to the movable plate 6 and slides along the guide rail 8 to achieve the guiding function. The rear end of the movable plate 6 and the front end of the slider 7 are fixedly connected.

[0021] A pneumatic rod 9 is fixedly connected to the side wall of the movable plate 6. The pneumatic rod 9 serves as a lifting power source, driving components such as the stop gauge 10 to move vertically. The movable plate 6 and the pneumatic rod 9 are fixedly installed and fixed together by multiple bolts. The output end of the pneumatic rod 9 is fixedly connected to the stop gauge 10. The stop gauge 10 serves as a core actuator, carrying signal detection-related components. A signal detection frame 11 is fixedly connected to the top of the stop gauge 10. The signal detection frame 11 provides a mounting carrier for the signal detector 14 and positions it for detection. An L-shaped plate 13 is fixedly connected to the bottom of the signal detection frame 11. The L-shaped plate 13 is used to fix the signal detector 14 and ensure its detection posture is stable. The signal detector 14 is fixedly connected to the L-shaped plate 13 (the signal detector 14 is a "diffuse reflection photoelectric sensor," and the through hole 12 is a "light-transmitting hole"; when material is placed on the signal detection frame 11, the material blocks the light emitted from the photoelectric sensor and passing through the through hole. The sensor does not receive the reflected light and outputs a "material present" signal; when there is no material, the light is unobstructed after passing through the through hole). The sensor receives reflected light (a reflector can be placed directly above the through hole) and outputs a "no material" signal. The signal detector 14 is used to detect whether the signal detection frame 11 is carrying material. The signal detection frame 11 has a through hole 12. The through hole 12 cooperates with the signal detector 14 to facilitate the detection of material. The through hole 12 is located directly above the signal detector 14. The opposite ends of the first mounting block 1 and the second mounting block 2 are fixedly connected to proximity switches 15. The proximity switches 15 are used to detect the position of the moving plate 6 and limit its movement range (the proximity switches 15 are electrically connected to the external control module through wires, and the control module is electrically connected to the drive circuit of the motor 3; when the moving plate 6 approaches the proximity switch 15, the proximity switch outputs an electrical signal to the control module, and the control module cuts off the motor drive circuit to stop the motor from rotating, thus achieving the limit. This technology is existing technology and will not be described in detail here). The opposite ends of the first mounting block 1 and the second mounting block 2 are respectively fixed to their corresponding proximity switches 15 by welding.

[0022] In this utility model: Horizontal position adjustment: Start motor 3, and the output end of motor 3 drives lead screw 5 to rotate through coupling 4; Since the moving plate 6 is threadedly connected to lead screw 5, and under the guidance of slider 7 (connected to moving plate 6) and guide rail 8 (fixed to first mounting block 1 and second mounting block 2), moving plate 6 will move smoothly along the axis of lead screw 5, thereby synchronously driving air rod 9, stop gauge 10, signal detection frame 11, L-shaped plate 13 and signal detector 14 to complete the horizontal position adjustment.

[0023] Vertical position adjustment: Activate the air spring 9, the output end of the air spring 9 extends and retracts, driving the stop gauge component 10, signal detection frame 11, L-shaped plate 13 and signal detector 14 to rise and fall, thereby realizing vertical position adjustment; through the linkage adjustment of the horizontal and vertical directions, the use requirements of the stop gauge structure in different scenarios can be met.

[0024] Safety limit and detection functions: The proximity switches 15 on the first mounting block 1 and the second mounting block 2 will limit the movement range of the moving plate 6 to prevent it from exceeding the safe travel and ensure the safe operation of the structure; at the same time, the signal detector 14 on the L-shaped plate 13 can detect in real time whether there is material being supported on the signal detection frame 11, so as to realize the monitoring of the material status.
