Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent treadmill manufacturing technology, and specifically discloses an intelligent treadmill roller manufacturing device. Background Technology
[0002] Treadmill rollers are the core components that support and drive the running belt, mainly consisting of the front drive rollers and the rear driven rollers. During the manufacturing process, drilling is required on the treadmill rollers. Firstly, this significantly reduces weight; drilling lowers the rollers' moment of inertia, allowing for faster motor start-up and shutdown, more responsive treadmill operation, and a smoother, more stable running experience—performance highly valued in high-end and commercial models. Secondly, drilling effectively reduces operating noise. When the running belt rotates at high speed, it compresses the air between the rollers, generating wind noise. Regularly distributed holes disperse and guide this airflow, resulting in a significant noise reduction effect.
[0003] Currently, the mainstream process for drilling treadmill rollers employs a parallel arrangement, where the electric drill gun and the roller's axis are held at the same height, and the roller is clamped and fixed using a fixture. However, this arrangement has significant limitations. First, because the roller is cylindrical and has a smooth surface, uneven or insufficient clamping force from the fixture can easily cause slight displacement, rotation, or vibration of the roller during processing when the drill gun applies radial thrust. This instability directly leads to deviations in drilling position accuracy and depth, affecting the consistency of the final product's quality. Second, this process has a low degree of automation. From loading and positioning the roller to completing the processing of multiple holes, frequent operator intervention is often required for operation, adjustment, and inspection. This not only increases the labor intensity of workers but also artificially lengthens the entire production cycle, resulting in low processing efficiency and difficulty in meeting the capacity and quality control requirements of large-scale production. Utility Model Content
[0004] In view of the problems of poor product quality consistency and low processing efficiency in the current treadmill roller production process, this utility model provides an intelligent treadmill roller production device.
[0005] To solve the above problems, this utility model provides the following technical solution: A smart treadmill roller production device includes a platform, on which a first support frame is fixedly mounted. An outer probe plate is fixedly mounted on one side of the top of the first support frame, and a carrier frame is fixedly mounted on the end of the outer probe plate. A vertically sliding electric drill gun is disposed inside the carrier frame. A positioning frame is disposed on the side of the first support frame and is fastened to the platform. A horizontally sliding base plate is mounted on the positioning frame, and a second support frame is fixedly mounted on the base plate. A frustum plate is rotatably disposed on the top of the second support frame, and a column is fixedly mounted on the frustum plate. A treadmill roller is fixedly mounted on the top of the column, and the treadmill roller is arranged below the electric drill gun.
[0006] Preferably, the side of the outer probe plate is provided with an adjusting rod that is fastened to the first support frame. The adjusting rod is arranged vertically and a fitting block is fixedly fitted on the outer wall. The fitting block is fastened to a horizontal rod.
[0007] Preferably, an electric push rod is fixedly installed on the top of the carrier frame. The electric push rod is arranged vertically, and the stroke end of the electric push rod is fastened to the electric drilling gun. Multiple vertically distributed stabilizing plates are fixedly installed on the carrier frame, and the stabilizing plates slide against the outer wall of the electric drilling gun.
[0008] Preferably, a connecting plate is fastened to the outer wall of the electric drilling gun, and a vertically arranged slide rod is fixedly installed on the connecting plate. The slide rod slides in cooperation with the carrier frame, and a limit ring is fastened around the slide rod.
[0009] Preferably, the positioning frame is provided with a through groove, the bottom end of the base plate is arranged in the through groove, a threaded rod is rotatably installed in the through groove, the bottom end of the base plate is rotatably engaged with the threaded rod, and the bottom end of the base plate is slidably engaged with the groove wall of the through groove.
[0010] Preferably, one end of the threaded rod is arranged on the outside of the positioning frame and a round rod is fixedly fitted thereon, and a through mounting hole is provided on the outer wall of the round rod.
[0011] Preferably, a rotating shaft is rotatably installed inside the second support frame. The top end of the rotating shaft is arranged above the second support frame and is fastened to the frustum plate. A first pulley is fastened to the outer wall of the rotating shaft. A servo motor is fixedly installed inside the second support frame. A second pulley is fastened to the output shaft end of the servo motor. The second pulley is connected to the first pulley in a driving connection.
[0012] Preferably, the bottom of the platform is equipped with a plurality of evenly arranged feet, and an electrical control box is fixedly installed on the side of the first support frame.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model features a high-level suspension structure above the platform, consisting of a first support frame, an outer probe plate, and a carrier frame. An electric drilling gun is vertically mounted here via an electric push rod. This layout allows the drill bit to apply force to the outer wall of the roller along the direction of gravity, avoiding roller displacement or vibration caused by lateral thrust. The treadmill roller to be processed is firmly mounted on a horizontally movable circular plate below via the column, forming a stable three-point support system. The above design ensures that at the moment of drilling, the roller bears a vertically downward pressure rather than a lateral force that is prone to deflection, thereby greatly enhancing the rigidity of the processing system, effectively eliminating drilling position deviation and depth inconsistency caused by workpiece instability, and significantly improving product quality consistency and processing accuracy. 2. This utility model achieves rapid and accurate initial positioning of the drilling station in the axial direction of the roller by rotating a threaded rod that passes through the slot of the positioning frame, which can precisely adjust the base plate supporting the entire roller fixture to slide back and forth. At the same time, through the rotation mechanism driven by the servo motor, pulley and rotating shaft, after the processing of one hole is completed, the servo motor can drive the rotating shaft to drive the top of the circular plate and the fixed roller to rotate precisely at a specific angle, and automatically send the next hole to be drilled to be directly below the electric drilling gun. This realizes continuous and automated processing of multiple holes around the roller, greatly reduces the number of manual interventions, shortens the processing cycle of a single product, and thus effectively meets the urgent need for efficiency in large-scale production. 3. This utility model has an adjustable camera module set on the side of the first support frame, which enables the operator to remotely observe the contact status between the drill bit and the workpiece and the operation status in real time, realizing process visualization. In addition, the entire platform is supported by four height-adjustable feet, ensuring that the equipment can be adjusted to a horizontal position during initial installation, providing a stable reference plane for all precision movements, and optimizing the controllability and reliability of the production process as a whole.
