Description

Technical Field

[0001] The utility model belongs to the technical field of quick-change mandrels for page wheels, and particularly relates to a quick-change mandrel adapted to a drum-type wire-drawing page wheel. Background Art

[0002] A page wheel, usually also known as a hundred-page wheel or a thousand-page wheel, is an abrasive coated tool mainly used for grinding and polishing. It consists of many abrasive cloth or sandpaper sheets bonded to a mesh cover made of plastic or fiber, arranged in a fan-shaped or radial pattern, resembling a wheel. These sheets can range from dozens to thousands, hence the names "hundred-page wheel" or "thousand-page wheel". The main difference between a hundred-page wheel and a thousand-page wheel lies in the number of sheets, but their functions are similar. They both achieve grinding, rust removal, paint removal, deburring, and weld grinding of metal or non-metal surfaces through high-speed rotation. They are suitable for different work requirements, such as shipbuilding, automobile manufacturing, aerospace, mechanical equipment, instrument manufacturing, bridge and construction projects, and furniture manufacturing industries.

[0003] During the use of the existing mandrel adapted to a drum-type wire-drawing page wheel, when the page wheel needs to be replaced, manual assistance is required for the assembly between the threads of the mandrel. This will result in a waste of installation time during the installation of the mandrel, thereby affecting the overall use efficiency and overall use effect of the device. Therefore, a quick-change mandrel adapted to a drum-type wire-drawing page wheel is proposed. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides a quick-change mandrel adapted to a drum-type wire-drawing page wheel, which can not only install the page wheel, but also quickly install the mandrel when installing the page wheel, thereby improving the overall use effect and overall use efficiency of the device.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a quick-change mandrel adapted to a drum-type wire-drawing page wheel, including a bottom plate. A horizontal movement mechanism is arranged on the top of the bottom plate. An up-and-down movement mechanism is arranged on the top of the horizontal movement mechanism. A quick-release mechanism is arranged on the up-and-down movement mechanism. The quick-release mechanism includes a rotating shaft arranged on the right side of the up-and-down movement mechanism. A square shaft is arranged on the left side of the rotating shaft. Guide grooves are respectively arranged at the front and rear ends of the square shaft. A page wheel is sleeved on the square shaft. A square tube is sleeved on the left side of the square shaft. Guide bars corresponding to the guide grooves are arranged inside the square tube. A sliding shaft is arranged on the left side of the square tube. The sliding shaft is welded to the square tube. A circular tube is arranged on the left side of the sliding shaft. A rotating shaft connected to the up-and-down movement mechanism is arranged on the left side of the circular tube. A spring is arranged on the sliding shaft. The left end of the spring is welded to the circular tube.

[0006] As a further improvement of the present utility model, the lateral movement mechanism includes fixed blocks arranged on the left and right sides of the bottom plate. In the middle of the two fixed blocks, there are chutes with openings facing upwards. Inside the two chutes, there are sliders respectively. Inside the two chutes, there is also a lead screw passing through the sliders. On the front sides of the two fixed blocks, there are first rotary motors connected to the lead screw respectively, and the first rotary motor and the lead screw are connected through a coupling.

[0007] As a further improvement of the present utility model, the up-and-down movement mechanism includes support rods arranged on the tops of the two sliders. On the outer ends of the tops of the two support rods, there are first round shafts respectively. On the outer ends of the two first round shafts, there are first synchronous belt pulleys connected to the round shafts respectively. At the bottoms of the outer ends of the two support rods, there are second round shafts respectively. At the end parts of the outer ends of the two second round shafts, there are second synchronous belt pulleys respectively. A transmission belt is jointly arranged between the first synchronous belt pulley and the second synchronous belt pulley.

On the inner ends of the two L-shaped plates, there are second rotary motors connected to the second synchronous belt pulley respectively, and the second rotary motor and the second synchronous belt pulley are connected through a coupling. In the middle of the two support rods, there are slideways respectively. Inside the two slideways, there are sliding bodies respectively. On the outer ends of the two sliding bodies, there are moving blocks connected to the transmission belt respectively. On the left moving block, there is a third rotary motor connected to the rotating shaft, and the right moving block is connected to the rotating shaft.

The switch is electrically connected to the first rotary motor, the second rotary motor, and the third rotary motor. At the four corners of the bottom of the bottom plate, there are support legs respectively. At the bottoms of the four support legs, there are anti-slip pads respectively.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
