Description

Technical Field

[0001] This invention relates to the field of lifting conveyor technology, and in particular to a lifting conveyor for cylinder production. Background Technology

[0002] In cylinder machining, assembly, repair, and assembly line conveying operations, the lifting conveyor is a core auxiliary equipment. It is mainly used to support various cylinder workpieces, and its height is adjustable to adapt to different processing stations, equipment heights, and manual operating heights, ensuring smooth workpiece conveying, docking, and assembly operations. Cylinder workpieces are mostly precision metal components, housing parts, and power components, requiring extremely high precision in height matching and operational stability. The height adjustment accuracy, transmission stability, and alignment accuracy of the lifting conveyor directly determine the machining and assembly accuracy of the cylinder workpieces, the efficiency of assembly line docking, and the product yield.

[0003] Traditional lifting and conveying equipment lacks a dedicated, precise scale structure. The lifting height relies solely on the equipment's preset stroke and manual visual judgment, resulting in significant height adjustment errors. In cylinder workpiece assembly lines and precision component assembly operations, even minor height deviations can easily lead to workpiece misalignment and excessive assembly gaps. This not only affects the quality of workpiece processing and assembly, easily causing rework and scrap, but also causes conveyor belt blockages and docking failures, significantly reducing production efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved The purpose of this invention is to provide a lifting conveyor for cylinder production, which solves the problem mentioned in the background art that traditional lifting conveyor equipment lacks a dedicated and precise scale matching structure, and the lifting height relies solely on the equipment's preset stroke and manual experience for visual judgment, resulting in large height adjustment errors.

A threaded conveying table is threadedly connected to the surface of the lead screw, and a scale plate is slidably connected to one side of the threaded conveying table. The scale plate serves to observe and adjust the height.

Several pressure sensors are installed on one side of the clamping plate, and a PLC controller is electrically connected to one side of the pressure sensors via a lead wire.

[0008] As a further embodiment of the present invention, the upright plate is fixedly connected to the two sides of the top surface of the thread conveying table, and the surface of the lead screw is protected by an external bellows cover. The bellows cover serves to protect the surface of the lead screw.

[0009] As a further embodiment of the present invention, one side of the electric push rod is electrically connected to a storage battery via a power cord, and the surface of the storage battery is provided with a protective shell, thereby providing continuous power supply.

[0010] As a further embodiment of the present invention, limit holes are provided on both sides of the surface of the threaded conveying table, and limit rods are slidably connected inside the limit holes. The limit rods serve to limit the movement of the threaded conveying table.

[0011] As a further embodiment of the present invention, a base is fixedly connected to the bottom of the upright frame, and a support plate is fixedly connected to one edge of the top surface of the base. The support plate serves to support the handrail.

[0012] As a further embodiment of the present invention, two fixed pulleys are fixedly connected to one side edge of the bottom of the base, and two movable pulleys are arranged directly opposite the fixed pulleys. Brake pads are installed inside both the fixed pulleys and the movable pulleys, and the brake pads play a braking role.

[0013] As a further embodiment of the present invention, a handrail is fixedly connected to one side of the support plate, and an anti-slip sleeve is fitted onto the surface of the handrail, thereby achieving the function of preventing slippage.

[0014] As a further embodiment of the present invention, a buffer pad is fixedly connected to the bottom of the threaded conveyor table. The buffer pad is made of silicone, and the buffer pad serves to prevent collisions and provide cushioning.

[0015] (III) Beneficial Effects This invention provides a lifting conveyor for cylinder production, which has the following advantages: 1. This cylinder production lifting conveyor, through its lifting mechanism, uses a drive motor fixed to the top surface of the extension block to rotate the lead screw. The lead screw drives the threaded conveyor to rise and fall smoothly in the vertical direction via threaded transmission. Simultaneously, the threaded conveyor slides along the surface of the scale plate, allowing operators to read the lifting height value in real time and intuitively, enabling micro-precision height adjustment and visual calibration. Combined with the limit rod limit guide and the bellows cover protective structure, it effectively improves the stability and structural safety of the lifting process. Overall, it effectively solves the problems of large lifting errors, low adjustment accuracy, and cumbersome alignment in traditional equipment, meeting the needs of high-precision conveying and assembly of cylinder workpieces.

[0016] 2. This cylinder production lifting conveyor, through its clamping mechanism, allows for bidirectional clamping and fixing of the cylinder workpiece placed on the threaded conveyor by extending electric push rods on both sides of the upright plate during use, driving the clamping plates to move synchronously. Pressure sensors on the surface of the clamping plates collect clamping pressure data in real time and transmit it to the PLC controller, enabling intelligent monitoring of clamping force. When the pressure value exceeds the preset safety range, the PLC controller immediately triggers an alarm light and sound warning, reminding the staff to adjust in time. This effectively avoids situations where excessive clamping damages the workpiece or excessive clamping causes the workpiece to slip or shift, ensuring the stability and safety of the workpiece conveying and lifting adjustment process.
