Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a dial precision positioning mechanism with feedback. Background Technology

[0002] A shift dial typically refers to a shift fork or lever in the transfer case's shift mechanism, widely used in vehicles requiring flexible power distribution, especially rugged off-road vehicles. It is driven by an electronically controlled mechanism (such as an electromagnetic coil) to engage and disengage a multi-plate clutch. The function of this shift dial is to distribute engine power, selectively sending power to the rear axle, or simultaneously to both the front and rear axles, thus enabling the vehicle to switch between rear-wheel drive and four-wheel drive.

[0003] In equipment such as transfer cases, precise positioning of the dial ensures accurate engagement and disengagement of multi-plate clutches, thereby achieving precise control of power output. This is crucial for the power requirements of vehicles under different road conditions. In existing technologies, due to certain clearances in the manufacturing and installation of transmission components such as gearboxes and gears, slight displacement deviations occur during power transmission, making it difficult to precisely position the dial. This leads to decreased equipment performance, increased operational errors, and seriously affects work efficiency and quality. Therefore, a dial precision positioning mechanism with feedback is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dial precision positioning mechanism with feedback, which aims to improve the problem of difficulty in precise positioning of the dial in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision positioning mechanism for a dial with feedback includes a housing. A bottom shell is fixedly connected to the bottom of the housing. A motor is fixedly connected to the top inner wall of the bottom shell. A rotating column is fixedly connected to the output end of the motor. A square turntable is fixedly connected to the outer wall of the rotating column. Multiple rotating shafts are fixedly connected to the bottom of the square turntable. An L-shaped connecting rod is rotatably connected to the outer wall of the rotating shafts. Multiple clamping blocks are slidably connected to the top of the housing. A rotating shaft is fixedly connected to the bottom of the clamping blocks. A mounting base is fixedly connected to the top of the housing. A dial is rotatably connected to the top of the mounting base. A feedback component for providing feedback on the dial's movement is fixedly connected to the outer wall of the dial.

[0007] As a further description of the above technical solution:

[0008] The feedback component includes a dial block, one end of which is fixedly connected to the outer wall of the dial. Two fixed posts are fixedly connected inside the housing. A sleeve is rotatably connected to the outer wall of the fixed posts. Two rotating plates are fixedly connected to the outer wall of the sleeve. Two signal transmitters are fixedly connected to the outer wall of the housing. Two sensor buttons are provided inside the signal transmitters.

[0009] As a further description of the above technical solution:

[0010] The top of the rotating column is rotatably connected to the bottom of the outer casing, and the other end of the L-shaped connecting rod is rotatably connected to the outer wall of the second rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The top of the outer shell is provided with multiple sliding grooves, and the outer wall of the clamping block is slidably connected to the inside of the sliding grooves;

[0013] As a further description of the above technical solution:

[0014] Multiple rotating shafts are slidably connected to the bottom of the housing, and a drive column is fixedly connected to the top of the dial;

[0015] As a further description of the above technical solution:

[0016] The bottom of the dial is fixedly connected to a connecting post, and the top of the connecting post is fixedly connected to the top of the mounting base.

[0017] As a further description of the above technical solution:

[0018] The outer casing has two rotating slots inside, and the two ends of the fixing column are fixedly connected to the inside of the rotating slots;

[0019] As a further description of the above technical solution:

[0020] One end of one of the rotating plates is in contact with the other end of the toggle block, and the other end of the other rotating plate is in contact with one of the sensing buttons.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this invention, a motor drives a rotating column to rotate, which in turn drives a square turntable to rotate. The rotation of the square turntable synchronously drives multiple rotating shafts and L-shaped connecting rods at the bottom, causing the clamping block to move towards the center along the slide groove. Ultimately, the clamping block clamps the mounting base, achieving precise positioning of the dial, improving the accuracy and reliability of equipment operation, ensuring the precise position of the dial during operation, thereby reducing the risk of misoperation and lowering maintenance costs.

[0023] 2. In this invention, the rotation of the drive column causes the dial to rotate on the mounting base, simultaneously driving the external lever to move synchronously. After the lever contacts the rotating block inside the housing, it causes the rotating block to swing, which in turn drives the external rotating plate through the sleeve. The swing of the external rotating plate causes it to contact the inductive button inside the signal transmitter, generating an electrical signal that is transmitted to the monitoring platform. This provides timely feedback on the dial's rotation status, allowing operators to make rapid adjustments, thereby improving the system's response speed and control accuracy, and ensuring the stability and efficiency of the equipment.

[0030] 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.

[0031] Reference Figures 2 to 4This utility model provides an embodiment of a precision positioning mechanism for a dial 13 with feedback, comprising a housing 1. The housing 1 serves as the external frame of the entire mechanism, providing structural support and protecting the internal precision components. A bottom shell 2 is fixedly connected to the bottom of the housing 1, providing protection and support for the positioning mechanism. A motor 3 is fixedly connected to the inner top wall of the bottom shell 2, serving as the drive source for the entire positioning mechanism and providing power to the positioning mechanism of the dial 13. A rotating column 4 is fixedly connected to the output end of the motor 3, with its top rotatably connected to the bottom of the housing 1. The rotating column 4 transmits the power of the motor 3. A square turntable 5 is fixedly connected to the outer wall of the rotating column 4. The design of the square turntable 5 makes the rotation smoother and reduces vibration and errors caused by irregular shape. The bottom of the square turntable 5 is fixedly connected to multiple rotating shafts 6. The outer wall of the rotating shaft 6 is rotatably connected to an L-shaped connecting rod 7. The rotating shaft 6 is the key component connecting the square turntable 5 and the L-shaped connecting rod 7. When the square turntable 5 rotates, the L-shaped connecting rod 7 is driven to rotate through the transmission action of the rotating shaft 6.

[0032] Multiple clamping blocks 9 are slidably connected to the top of the outer casing 1. Multiple sliding grooves 10 are provided on the top of the outer casing 1, providing sliding tracks for the clamping blocks 9. The outer walls of the clamping blocks 9 are slidably connected to the inside of the sliding grooves 10. The four clamping blocks 9 can slide freely and synchronously along the sliding grooves 10 as needed to adapt to the centering and clamping requirements of workpieces of different sizes and shapes. A rotating shaft 2 8 is fixedly connected to the bottom of the clamping blocks 9. The rotating shaft 2 8 drives the clamping blocks 9 to move. Multiple rotating shafts 2 8 are slidably connected to the bottom of the outer casing 1, thus stabilizing the movement of the rotating shafts 2 8 and ensuring that the rotating shafts 2 8 only perform linear motion. The other end of an L-shaped connecting rod 7 is rotatably connected to the outer wall of the rotating shaft 2 8. The movement of the L-shaped connecting rod 7 drives the rotating shaft 2 8 to perform linear motion, thereby driving the clamping blocks 9 to move.

[0033] A mounting base 11 is fixedly connected to the top of the outer casing 1. The mounting base 11 provides a stable mounting platform for subsequent mechanisms. A dial 13 is rotatably connected to the top of the mounting base 11. The dial 13 is a key component for fine adjustment. A connecting post 12 is fixedly connected to the bottom of the dial 13. The top of the connecting post 12 is fixedly connected to the top of the mounting base 11, connecting the dial 13 to the mounting base 11 and enabling the dial 13 to rotate on the mounting base 11. A drive post 14 is fixedly connected to the top of the dial 13. The drive post 14 is used to connect to an external drive mechanism to drive the dial 13 to rotate. A feedback component for providing feedback on the movement of the dial 13 is fixedly connected to the outer wall of the dial 13.

[0034] Reference Figures 1 to 2The feedback component includes a lever 15, one end of which is fixedly connected to the outer wall of the dial 13. The lever 15 is one of the core components of the feedback component, and it moves with the rotation of the dial 13. Two fixed posts 17 are fixedly connected inside the housing 1, serving as supports and positioning elements. Two rotating slots 16 are formed inside the housing 1, with both ends of the fixed posts 17 fixedly connected to the inside of the rotating slots 16. The rotating slots 16 provide mounting support points for the fixed posts 17 and also provide a spatial basis for the rotation of subsequent mechanisms. A sleeve 18 is rotatably connected to the outer wall of the fixed posts 17, allowing free rotation around them. Two rotating plates 19 are fixedly connected to the outer wall of the sleeve 18. One end of one rotating plate 19 contacts the other end of the lever 15. The rotation of the dial 13 drives the lever 15 to move. When the lever 15 contacts one of the rotating plates 19, it causes the plate to rotate, which in turn drives the other rotating plate 19 to rotate through the sleeve 18. Two signal transmitters 20 are fixedly connected to the outer wall of the housing 1. The signal transmitters 20 are used to receive and process signals from the feedback component. Two sensing buttons 21 are provided inside the signal transmitters 20. The other end of another rotating plate 19 is in contact with one of the sensing buttons 21. When the other rotating plate 19 rotates, the sensing button 21 is pressed, so that the signal transmitter 20 receives and transmits the signal, so as to facilitate timely feedback on the rotation of the dial 13.

[0035] Working principle: When positioning the dial 13, the motor 3 is turned on, and the motor 3 drives the rotating column 4 to rotate, which in turn drives the square turntable 5 to rotate. When the square turntable 5 rotates, it drives the multiple rotating shafts 6 at the bottom to rotate synchronously, which in turn drives the L-shaped connecting rod 7 to swing. The swing of the L-shaped connecting rod 7 drives the clamping block 9 to move towards the center along the slide groove 10 through the transmission action of the rotating shaft 8, thereby completing the centering and clamping of the mounting base 11, thus achieving precise positioning of the dial 13.

[0036] The drive column 14 is then driven to rotate by an external drive device, which causes the dial 13 to rotate on the mounting base 11. When the dial 13 rotates, it drives the external lever 15 to move synchronously. When the lever 15 contacts the rotating block inside the housing 1, it drives the internal rotating block to swing. This, in turn, drives the external rotating plate 19 to swing through the transmission action of the sleeve 18. When the external rotating plate 19 swings, it contacts the sensing button 21 inside the signal transmitter 20, thereby generating an electrical signal. This signal is received by the signal transmitter 20 and transmitted to the monitoring platform, thus enabling timely feedback on the rotation status of the dial 13.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
