Description

Technical Field

[0001] This application relates to the field of spring manufacturing, and in particular to an auxiliary device for facilitating the replacement of grinding wheels on a spring grinding machine. Background Technology

[0002] Spring grinding machines are automated or semi-automatic equipment specifically designed for grinding the ends or surfaces of springs. They are widely used in the spring manufacturing industry. The grinding wheel of the spring grinding machine is the core tool for spring grinding, and its performance directly affects the processing accuracy, surface quality, and production efficiency of the spring. Over time, the grinding wheel will gradually lose its effective grinding ability. If it is not replaced in time, it will directly affect the processing accuracy, production efficiency, and even equipment safety. The grinding wheel diameter of large spring grinding machines is over 250mm, the thickness is over 40mm, and the weight can reach over 8 kg. In actual operation, two people are required to replace the grinding wheel. During the operation, the new grinding wheel needs to be aligned with the spindle. During this process, the worker needs to keep the grinding wheel in a vertical position off the ground at all times. Manual operation is labor-intensive and can easily cause back sprains for workers. Utility Model Content

[0003] To reduce the labor intensity of workers and improve the convenience of changing grinding wheels, this application provides an auxiliary device for facilitating the replacement of grinding wheels on a spring grinding machine.

[0004] This application provides an auxiliary device for easily replacing the grinding wheel of a spring grinding machine, which adopts the following technical solution: An auxiliary device for facilitating the replacement of grinding wheels on a spring grinding machine includes a movable platform, a lifting rod, an electric hoist, and a placement seat. Rollers are evenly distributed on the bottom of the movable platform. The lifting rod is mounted on the movable platform, and the electric hoist is mounted on the lifting rod. The placement seat is slidably connected to the movable platform in a vertical direction. The hook of the electric hoist is attached to the placement seat, and the placement seat is used to keep the grinding wheel in a vertical position.

[0005] By adopting the above technical solution, a mobile platform with rollers is set up to enable flexible movement of the device. The electric hoist on the lifting rod drives the placement seat to slide vertically. The placement seat is specifically designed to keep the grinding wheel in a vertical position, eliminating the need for manual lifting of the grinding wheel. The electric hoist can drive the grinding wheel to rise and fall, and the placement seat stably maintains the vertical position of the grinding wheel, reducing manual labor consumption, enabling single-person operation, and reducing labor intensity and the risk of back injury.

[0006] Optionally, the placement seat includes a sliding plate, a support plate, two abutment plates, and two limiting plates. The sliding plate is slidably connected to the moving platform in a vertical direction. The support plate is disposed on the sliding plate and is used to support the bottom of the grinding wheel. The two abutment plates are slidably connected to the sliding plate in a horizontal direction that is close to or away from the sliding plate. The two abutment plates are respectively used to abut the side wall of the grinding wheel. The two limiting plates correspond to the two abutment plates and are disposed on the abutment plates. The limiting plates are used to fit the end face of the grinding wheel against the sliding plate.

[0007] By adopting the above technical solution, the placement seat supports the bottom of the grinding wheel through the support plate, two sliding abutment plates abut against the side wall of the grinding wheel, and two limiting plates make the end face of the grinding wheel fit against the sliding plate. The grinding wheel is stably fixed from three dimensions: bottom support, side wall abutment, and end face fit, which avoids the grinding wheel shaking, solves the instability problem when manually supported, and provides a basis for the precise alignment of the grinding wheel and the spindle.

[0008] Optionally, the placement base is further provided with a driving component for the two abutment plates to maintain contact with the sidewall of the grinding wheel. The driving component includes two racks, two springs, and a gear. The gear is rotatably connected to the placement base. The two racks correspond to the two abutment plates. The length direction of the racks is parallel to the sliding direction of the abutment plates. One end of each rack is placed on the abutment plate. The two racks are located on both sides of the gear. The racks and gears are engaged. The two springs correspond to the two abutment plates. The two springs are used to bring the two abutment plates closer together.

[0009] By adopting the above technical solution, the spring force can make the abutment plate automatically adapt to grinding wheels of different diameters and maintain the abutment state. The linkage structure of the gear and rack ensures that the two abutment plates slide synchronously without manual adjustment and fixing, which improves the device's adaptability to grinding wheels of different specifications and ease of operation.

[0010] Optionally, the limiting plate is provided with an adapting inclined surface, which is used to abut against the outer edge of a grinding wheel of different thicknesses.

[0011] By adopting the above technical solution, the grinding wheels are available in different thicknesses. The limiting plate has an adaptable inclined surface to abut against the outer edge of grinding wheels of different thicknesses, so that the limiting plate can fit the outer edge of grinding wheels of different thicknesses. This allows the device to adapt to grinding wheels of various thicknesses without replacing the limiting plate, thus enhancing the versatility of the device and reducing the adjustment cost when changing different grinding wheels.

[0012] Optionally, the sliding plate has a clearance groove on its end face facing the grinding wheel to avoid the grinding spring machine spindle.

[0013] By adopting the above technical solution, mechanical interference between the mounting base and the spindle is avoided, ensuring that the grinding wheel is unobstructed as it approaches the spindle, allowing the grinding wheel to be more smoothly aligned with the spindle mounting position and improving the smoothness of the replacement operation.

[0014] Optionally, the movable platform includes a base, a lifting seat, and a fine adjustment component. The rollers are disposed on the base, the lifting seat is slidably connected to the base in a vertical direction, and the fine adjustment component is used to change the distance between the base and the lifting seat.

[0015] By adopting the above technical solution, the height position of the grinding wheel can be flexibly adjusted through the sliding of the lifting seat and the precise control of the fine adjustment components, solving the problem of insufficient precision when manually adjusting the height, shortening the alignment time between the grinding wheel and the spindle, and improving the replacement efficiency.

[0016] Optionally, the fine adjustment component includes a screw and a handle. The screw is vertically arranged and rotatably connected to the base. The lifting seat is threadedly connected to the screw, and the handle is disposed on the screw.

[0017] By adopting the above technical solution, the screw drive has high-precision adjustment characteristics. With the throttle, the height of the lifting seat can be adjusted slightly, making operation simple and labor-saving, and further improving the accuracy and convenience of aligning the grinding wheel and the spindle.

[0018] Optionally, the roller is a swivel wheel, and the roller is rotatably connected to a brake pad.

[0019] By adopting the above technical solution, the caster wheel enables the device to move flexibly, making it easy to push it precisely to the replacement position next to the spring grinding machine; the brake pad can fix the position of the device, preventing the device from accidentally sliding during the replacement process, thus improving operational stability and safety.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The wheeled mobile platform allows for flexible movement, while the electric hoist drives the placement seat to rise and fall. The placement seat is specifically designed to keep the grinding wheel vertical. No manual lifting or support of the grinding wheel is required, enabling single-person operation, reducing physical exertion, avoiding the risk of back injury, and significantly improving operational safety. 2. The grinding wheel is fixed in three dimensions from the bottom, side wall, and end face by a support plate, abutment plate, and limit plate; the gear and rack linkage structure cooperates with the spring to make the abutment plate automatically adapt to grinding wheels of different diameters and maintain contact; the clearance groove avoids interference with the spindle, and the lifting seat and screw fine adjustment structure achieve precise height control.
