Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of elevator seat plate processing equipment, specifically an elevator seat plate processing table. Background Technology
[0002] In the elevator manufacturing industry, the seat plate, as a core load-bearing component, directly affects the elevator's operational safety and lifespan due to its machining accuracy (such as the dimensional tolerances and surface finish of positioning holes and mounting slots). Traditional machining equipment has the following drawbacks: 1. Limited accuracy: The Z-axis lifting mechanism often relies on hydraulic or ordinary lead screws, which are easily affected by lateral forces, causing swaying and resulting in out-of-tolerance hole perpendicularity; 2. Poor dynamic stability: The horizontal moving frame lacks anti-tipping design, and machining vibrations can easily cause tool chatter, affecting surface quality.
[0003] Although some equipment has attempted to incorporate multi-axis moving platforms, problems such as insufficient transmission rigidity and redundant guide structures (e.g., high cost of linear guides) remain unresolved. Therefore, there is an urgent need to develop a specialized processing equipment that combines multi-dimensional precision positioning with high rigidity and vibration resistance to meet the precision and efficiency requirements of mass production of elevator seat panels. Utility Model Content
[0004] This utility model provides an elevator seat plate processing table, which overcomes the shortcomings described in the background art.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An elevator seat processing table includes a first movable frame, a guide rail frame, a second movable frame, and a processing device. The first movable frame moves along the guide rail frame, and the second movable frame moves along the first movable frame. The processing device is mounted on the second movable frame via an adjustment assembly. The adjustment assembly includes a base frame, an adjustment motor, a threaded rod, and a threaded seat. The threaded rod is mounted on the output end of the adjustment motor and is threadedly connected to the threaded seat. The processing device is mounted on the bottom end of the threaded seat via a locking frame. A protrusion is provided on the side end of the base frame, and an auxiliary frame with rollers is locked on the side end of the threaded seat. The rollers are adapted to the protrusion and move precisely in the vertical direction. At least two rollers are symmetrically installed at the points where the first movable frame moves along the guide rail frame and the second movable frame moves along the first movable frame. The guide rail frame and the first movable frame also have another protrusion with the same structure as the aforementioned protrusion.
[0007] The elevator seat processing table achieves large-range positioning along the X-axis by moving the first moving frame along the guide rail frame, and achieves Y-axis positioning by moving the second moving frame along the first moving frame. The two work together to ensure the precise two-dimensional positioning of the processing device in the horizontal plane.
[0008] The adjustment assembly utilizes an adjusting motor to drive a threaded rod, which in turn moves the threaded seat and the machining device mounted on it to Z-axis displacement. The precise matching rolling of the rollers on the auxiliary frame at the side of the threaded seat with the protrusions on the side of the base frame effectively withstands lateral forces and bending moments, guiding the machining device to move with high precision and linearity along the vertical direction, thus achieving precise positioning of the machining head in three-dimensional space. Simultaneously, the moving frame, guide rail, and base frame all employ symmetrically distributed rollers and protrusions. This design not only provides precise linear guidance and uniform load capacity for horizontal movement but also significantly enhances the rigidity, smoothness of movement, and anti-tipping ability of the entire system. The structure effectively suppresses machining vibration, ensuring the stability of the machining process and improving the machining accuracy and surface quality of holes and grooves in the elevator seat plate. The overall structure is compact, with good coordination of movements at each level, comprehensively improving machining efficiency and product quality.
[0009] A preferred technical solution: An active motor is installed on the first moving frame, and the output end of the active motor directly or indirectly drives the corresponding wheel to move along the guide rail frame.
[0010] A preferred technical solution: Both sides of the first moving frame are equipped with active motors.
[0011] A preferred technical solution: The second moving frame cooperates with the first moving frame via a first cable chain, and the first moving frame cooperates with the guide rail frame via a second cable chain. The robust cable chain housing provides mechanical protection for the internal pipelines, such as resisting accidental impacts, while also isolating operators from the risk of contact with live wiring.
[0012] A preferred technical solution: The processing device includes a drive motor and a grinding head, and the grinding head is installed at the output end of the drive motor.
[0013] A preferred technical solution: the grinding head is a drill bit or a polishing disc.
[0014] A preferred technical solution: A discharge frame is provided vertically at the guide rail frame, and a discharge port is provided on the discharge frame. An openable baffle is installed at the discharge port, and the two sides of the baffle are installed at the discharge port through a rotating shaft.
[0015] A preferred technical solution: A slope plate is provided on the inner side of the discharge port.
[0016] By adopting the above technical solution, the beneficial effects of this utility model are:
[0017] 1. This utility model achieves a repeatability positioning accuracy of ±0.1mm for the processing device by using a three-level coordination of the guide rail frame (X-axis), the second moving frame (Y-axis), and the threaded lifting adjustment component (Z-axis), combined with a roller-protrusion symmetrical guide structure. This solves the problem of excessive hole perpendicularity in traditional equipment and meets the strict tolerance requirements of elevator seat plates.
[0018] 2. The first moving frame in this utility model adopts a dual-sided active motor drive + symmetrical roller protrusion guide, which improves the anti-overturning ability and eliminates displacement drift caused by processing off-center load.
[0019] 3. In this utility model, the Z-axis threaded transmission is supplemented by rollers for forced vertical guidance, which enhances rigidity. Lateral forces are borne by the protruding structure, effectively suppressing tool chatter.
[0020] 4. The sloping discharge port in this utility model guides the finished product to slide out, making it easy to remove the elevator seat plate from the side. Attached Figure Description
