Description

Technical Field

[0001] The utility model relates to a mobile rotary grinding platform Background Art

[0002] Most of the existing grinding conditions use a hand-held grinding machine to grind workpieces, or use a belt sander to pick up the workpiece to be ground and place it on the belt sander for grinding. There are some drawbacks in the original process. First, it is quite labor-consuming. When the grinding piece is relatively large and heavy, holding it for a long time is exhausting and the efficiency is low. Another point is safety. For example, with a hand-held grinding machine, one has to hold the grinding machine tightly with both hands all the time. During grinding, the equipment vibrates greatly, and after a long time, the body gets fatigued. Moreover, once the grinding disc of the grinding machine wears out and is used improperly, it may break, easily causing mechanical injuries. Summary of the Invention

[0003] The present invention provides a mobile rotary grinding platform to solve the problem of grinding circular equipment.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0005] The mobile rotary grinding platform of the utility model includes a rotary table, a belt sander, a hydraulic strut, and a fixed frame;

[0006] The rear part of the belt sander is hinged to the fixed frame. The grinding surface of the belt sander faces downward towards the rotary table. A hydraulic strut is provided in the middle of the belt sander to connect to the fixed frame. The hydraulic strut supports the grinding machine to swing up and down at the hinged position and swing downward to contact the grinding workpiece on the rotary table.

[0007] According to the above-mentioned mobile rotary grinding platform, the rotary table is arranged on the rotary frame through a slewing bearing. A universal wheel is also provided around the slewing bearing to support the rotation of the rotary table.

[0008] According to the above-mentioned mobile rotary grinding platform, the bottom of the rotary frame is provided with rollers, and there is also a guide rail. The rollers run on the guide rail. One end of the guide rail is on one side of the fixed frame, and a limit block is provided at the end of the guide rail.

[0009] According to the above-mentioned mobile rotary grinding platform, the fixed frame is a gantry frame. An ear plate protruding outside is provided on one side of the top, and a pin shaft is provided inside the ear plate to connect the belt sander.

[0010] According to the above-mentioned mobile rotary grinding platform, the lower part of the ear plate of the fixed frame is hinged to the fixed end of the hydraulic strut, the movable end of the hydraulic strut is hinged to the middle position of the lower part of the belt sander, and a handle is provided on one side of the lower part of the belt sander.

[0011] According to the above-mentioned mobile rotary grinding platform, the rotary table is a circular metal plate, and a fixing member is provided on the middle surface of the top to fix the product to be ground.

[0012] After the device is used, the grinding quality can be improved, and the parts to be ground are relatively regular. The safety of the device for grinding is improved compared with the existing equipment, reducing mechanical injuries; the device is easy to operate, labor-saving, reduces manual consumption, and improves the grinding efficiency.

[0019] The following further describes the specific content of the present utility model:

[0020] The moving and rotating grinding platform of the present utility model includes a rotary table, a belt sander 1, a hydraulic strut 3 and a fixed frame 2.

[0021] The rear part of the belt sander 1 is hinged to the fixed frame 2, the grinding surface of the belt sander 1 faces downward towards the rotary table, and a hydraulic strut 3 is provided in the middle of the belt sander 1 to connect to the fixed frame 2. The hydraulic strut 3 supports the grinding machine to swing up and down at the hinge position and contacts the workpiece to be ground on the rotary table when swinging downward. Through the telescopic damping of the 3 hydraulic struts, the power consumption of manually lifting the belt sander is reduced, effectively ensuring smooth grinding.

[0022] In this device, the rotary table is arranged on the rotary frame through a rotary bearing 7, and universal wheels 9 are also provided around the rotary bearing 7 to support the rotation of the rotary table. The bottom of the rotary frame is provided with rollers 8, and a guide rail 6 is also provided. The rollers 8 run on the guide rail 6. One end of the guide rail 6 is on one side of the fixed frame 2, and a limit block is provided at the end of the guide rail 6. The height is leveled with a spirit level, and longitudinally it is ensured to be parallel to the sanding working surface of the belt sander. The guide rail is fixed to the ground with expansion bolts, and baffles are welded at both ends of the guide rail as limit blocks to prevent the platform from derailing.

[0023] The fixing frame 2 is a gantry. There is an ear plate protruding outside on one side of the top. A pin shaft is arranged inside the ear plate to connect the abrasive belt machine 1. The lower part of the ear plate of the fixing frame 2 is hinged to the fixed end of the hydraulic strut 3. A support is welded at the rear side of the bottom of the abrasive belt machine. The movable end of the hydraulic strut 3 is hinged to the lower support of the abrasive belt machine 1 and is connected to the ear plate with a pin shaft.

[0024] On one side of the lower part of the abrasive belt machine 1, there is a handle 10. It is used to control the lifting or lowering of the abrasive belt machine to work. This handle is equipped with a switch button, which can control the operation and stop of the abrasive belt machine. There is an emergency stop switch on the upper side, and the equipment can be powered off for protection at any time in case of an emergency.

[0025] The rotary table is a circular metal plate. There is a fixing part on the middle surface of the top for fixing the product to be polished.

[0026] The end face of the special roller at the bottom of the moving platform is machined with a V-shaped groove and is directly located on the guide rail surface. The guide rail surface is tangent to both sides of the V-shaped groove to prevent the platform from moving. A brake pedal is installed on the front roller. After stepping on the brake pedal, the platform is fixed to a position, so that the polishing is more stable. The rotary table can be installed on the upper side. The table top of the rotary table is made of composite nylon plate. This material has good strength and toughness and is relatively light in weight, reducing the manual consumption of pushing and pulling the workbench back and forth. Fixing parts are installed in the middle for fixing the equipment to be polished.

[0027] This device uses a traditional abrasive belt machine for production and does not require operation in a holding and polishing room. During polishing, by operating the handle to lift or lower, the hydraulic strut is driven to expand and contract, and the height of the abrasive belt machine is adjusted. There is a switch button on the handle, and the operation is simple. The operation of the abrasive belt machine can be controlled at any time. There is an emergency stop switch on the upper side, and the power can be cut off at any time in case of an emergency, improving safety. There is a moving platform on the lower side, and the rollers move linearly on the guide rail, and the polishing is stable and relatively uniform. There is a rotating platform on the upper side. Instead of moving the workpiece back and forth, only by rotating the platform, multi-station polishing can be carried out.
