Description

Technical Field

[0001] This utility model relates to the field of solid shaft technology, specifically to a solid shaft total length detection and transfer device. Background Technology

[0002] The automotive driveshaft is a crucial connecting component in a vehicle's transmission system, responsible for transmitting power. Its function, along with the gearbox and drive axle, is to transfer engine power to the wheels, thus driving the vehicle. Specialized automotive driveshafts are typically used in vehicles such as tanker trucks, water trucks, sewage suction trucks, fire trucks, and high-pressure cleaning trucks. An automotive driveshaft is generally a circular component that can be connected or assembled, and can move and rotate. It consists of three key components: a shaft tube, a telescopic sleeve, and a universal joint, which work together to function. The driveshaft is the power-transmitting shaft in a universal joint drive system. In front-engine, rear-wheel-drive vehicles, it transmits the rotation of the transmission to the final drive. It can consist of several sections connected by universal joints.

[0003] Currently, most automotive driveshafts use solid alloy steel tubing with excellent torsional resistance. During machining, long sections of this tubing are first sawn into smaller segments of predetermined length before being fed into a machine tool for grinding, polishing, and other processing. However, the inventors of this application discovered through on-site observation that the current process of feeding these smaller segments into the machine tool does not accurately measure their total length. This results in substandard solid shafts being used in subsequent processing steps, severely impacting the machining quality of the shafts. Utility Model Content

[0004] In view of the technical problem that the total length of small solid shaft workpieces is not accurately detected during the process of loading them onto the machining tool, resulting in solid shafts with non-standard total lengths flowing into subsequent processing steps, which seriously affects the machining quality of solid shafts, this utility model provides a solid shaft total length detection and transfer device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A solid shaft total length detection and transfer device includes a support frame, a support mechanism, an estimation mechanism, a detection mechanism, and a transfer mechanism. The support mechanism, estimation mechanism, and detection mechanism are mounted on the support frame. The support mechanism is adapted to support a solid shaft that is automatically fed in. The estimation mechanism is adapted to push and position the solid shaft supported on the support mechanism. The detection mechanism is adapted to detect the total length of the solid shaft positioned by the estimation mechanism. The transfer mechanism is adapted to transfer and store solid shafts whose total length exceeds a predetermined range, and to feed solid shafts whose total length is within the predetermined range into an existing machine tool. The estimation mechanism, detection mechanism, and transfer mechanism are electrically connected to a controller mounted on the support frame.

[0007] Compared with existing technologies, the solid shaft total length detection and transfer device provided by this utility model first uses a locating mechanism to push and position the solid shaft supported on the support mechanism. Then, a detection mechanism detects the total length of the solid shaft positioned by the locating mechanism. Next, a transfer mechanism transfers and stores solid shafts whose total length exceeds a predetermined range, and solid shafts whose total length is within the predetermined range are loaded into existing machine tools for processing. Thus, by first pushing and positioning the automatically fed solid shafts, and then detecting the total length of the positioned solid shafts, this application can detect the total length of each solid shaft based on the same positioning benchmark, thereby improving the accuracy of the total length detection of solid shaft workpieces. Furthermore, by transferring and storing solid shafts whose total length exceeds the predetermined range, it avoids solid shafts with non-standard total lengths from flowing into subsequent processing steps, thus improving the processing quality of solid shafts.

[0008] Furthermore, the support mechanism includes a first support seat and a second support seat fixed at intervals on the surface of the support frame, and the surfaces of the first support seat and the second support seat are provided with support grooves.

[0009] Furthermore, the estimation mechanism includes a positioning plate and a push cylinder connected to the controller via a wire. The positioning plate is fixed to the support frame surface at the outer end of the first support base, and the push cylinder is fixed to the support frame surface at the outer end of the second support base. A push block is fixedly connected to the piston rod of the push cylinder near the outer end of the second support base.

[0010] Furthermore, the detection mechanism includes a light-blocking plate and an infrared rangefinder connected to the controller via a wire. The light-blocking plate is fixed to the top of the push block, and the infrared rangefinder is fixed to the top of the push cylinder and is positioned opposite to the light-blocking plate.

[0011] Furthermore, the transfer mechanism includes a storage box and a robotic arm connected to the controller via a wire. The storage box is tilted and fixed to the top of an existing automatic solid shaft feeding device next to the support frame. The robotic arm is adapted to transfer solid shafts with a total length exceeding a predetermined range to the storage box for storage, and to feed solid shafts with a total length within the predetermined range into an existing processing machine tool.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] 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; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please refer to Figure 1As shown, this utility model provides a solid shaft total length detection and transfer device, including a support frame 1, a support mechanism 2, a estimation mechanism 3, a detection mechanism 4, and a transfer mechanism 5. The support mechanism 2, the estimation mechanism 3, and the detection mechanism 4 are arranged on the support frame. The support mechanism 2 is adapted to support the solid shaft 6 that is automatically fed by an existing solid shaft automatic feeding device. The estimation mechanism 3 is adapted to push and position the solid shaft supported on the support mechanism 2. The detection mechanism 4 is adapted to detect the total length of the solid shaft positioned by the estimation mechanism 3. The transfer mechanism 5 is adapted to transfer and store solid shafts whose total length exceeds a predetermined range, and to feed solid shafts whose total length is within the predetermined range into an existing processing machine tool. The estimation mechanism 3, the detection mechanism 4, and the transfer mechanism 5 are electrically connected to a controller (not shown in the figure) installed on the support frame 1. The controller can be implemented using an existing PLC controller.

[0018] Compared with existing technologies, the solid shaft total length detection and transfer device provided by this utility model first uses a locating mechanism to push and position the solid shaft supported on the support mechanism. Then, a detection mechanism detects the total length of the solid shaft positioned by the locating mechanism. Next, a transfer mechanism transfers and stores solid shafts whose total length exceeds a predetermined range, and solid shafts whose total length is within the predetermined range are loaded into existing machine tools for processing. Thus, by first pushing and positioning the automatically fed solid shafts, and then detecting the total length of the positioned solid shafts, this application can detect the total length of each solid shaft based on the same positioning benchmark, thereby improving the accuracy of the total length detection of solid shaft workpieces. Furthermore, by transferring and storing solid shafts whose total length exceeds the predetermined range, it avoids solid shafts with non-standard total lengths from flowing into subsequent processing steps, thus improving the processing quality of solid shafts.

[0019] For a specific embodiment, please refer to Figure 1 As shown, the support mechanism 2 includes a first support seat 21 and a second support seat 22 fixed at intervals on the surface of the support frame 1. The surfaces of the first support seat 21 and the second support seat 22 are provided with support grooves 23, so that the solid shaft fed from the existing solid shaft automatic feeding device can automatically roll into the support grooves 23 of the first support seat 21 and the second support seat 22 to achieve support.

[0020] For a specific embodiment, please refer to Figure 1As shown, the estimation mechanism 3 includes a positioning plate 31 and a push cylinder 32 connected to the controller via a wire. The positioning plate 31 is fixed to the surface of the support frame 1 at the outer end of the first support seat 21, and the push cylinder 32 is fixed to the surface of the support frame 1 at the outer end of the second support seat 22. That is, the positioning plate 31 and the push cylinder 32 are fixed to the outer ends of the two support seats respectively. A push block 33 is fixedly connected to the piston rod of the push cylinder 32 near the outer end face of the second support seat 22. Thus, under the control of the controller, the piston rod of the push cylinder 32 can drive the push block 33 to move towards the second support seat 22, thereby bringing the solid shafts supported on the first support seat 21 and the second support seat 22 closer to the positioning plate 31 and finally abutting against the positioning plate 31. This achieves the pushing and positioning of the supporting solid shafts and ensures that the positioning reference of each solid shaft is the same.

[0021] For a specific embodiment, please refer to Figure 1 As shown, the detection mechanism 4 includes a light-blocking plate 41 and an infrared rangefinder 42 connected to the controller via a wire. The light-blocking plate 41 is fixed on the top of the push block 33, and the infrared rangefinder 42 is fixed on the top of the push cylinder 32 and is positioned opposite to the light-blocking plate 41. In this way, the infrared rays emitted by the infrared rangefinder 42 can be reflected back by the light-blocking plate 41. The specific structure of the infrared rangefinder 42 is existing technology well known to those skilled in the art and will not be described in detail here. The detection mechanism 4 provided in this embodiment fixes the light-blocking plate 41 to the top of the pushing block 33 and the infrared rangefinder 42 to the top of the pushing cylinder 32, which is positioned opposite to the light-blocking plate 41. Thus, when the piston rod of the pushing cylinder 32 moves the pushing block 33 towards the second support seat 22, the light-blocking plate 41 moves along with the pushing block 33. Both ends of the solid shaft are positioned against the positioning plate 31 and the pushing block 33. At this time, the controller controls the infrared rangefinder 42 to accurately measure the distance between itself and the light-blocking plate 41, and the infrared rangefinder 42 returns the distance measurement result to the controller. If the total length of the positioned solid shaft exceeds (is greater than or less than) a predetermined range, the distance the piston rod of the pushing cylinder 32 moves the pushing block 33 towards the second support seat 22 will be too little or too much. Correspondingly, the distance measured by the infrared rangefinder 42 between itself and the light-blocking plate 41 will be too small or too large. Therefore, the distance between the infrared rangefinder 42 and the light-blocking plate 41 can be used to determine whether the total length of the solid shaft meets the standard.

[0022] For a specific embodiment, please refer to Figure 1As shown, the transfer mechanism 5 includes a storage box 51 and a robotic arm (not shown) connected to the controller via a wire. The storage box 51 is tilted and fixed to the top of the existing automatic solid shaft feeding device 100 next to the support frame 1. The robotic arm is adapted to transfer solid shafts with a total length exceeding a predetermined range to the storage box 51 for storage, and to feed solid shafts with a total length within the predetermined range to an existing machine tool for processing. The specific structure of the robotic arm is prior art well known to those skilled in the art and will not be described in detail here. In this embodiment, the transfer mechanism 5 allows the robotic arm to perform corresponding operations based on the distance measurement results returned by the controller. If the total length exceeds the predetermined range, the controller controls the robotic arm to transfer the solid shaft to the storage box 51 for storage; conversely, if the total length is within the predetermined range, the robotic arm feeds the solid shaft to an existing machine tool for subsequent processing. This effectively prevents solid shafts with a total length that does not meet the standard from flowing into subsequent processing steps, thus improving the processing quality of the solid shafts.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model 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 this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
