Description

Technical Field

[0001] The present invention specifically relates to a handheld multi-functional wooden door grinding device. Background Art

[0002] The grinding of wooden doors is an important step in the surface treatment of wooden doors. The purpose is to remove the defects on the door surface, maintain a smooth and flat effect, and prepare for painting or oiling.

[0003] When grinding wooden doors with a handheld grinding machine, generally rough grinding or fine grinding is carried out. When switching between rough grinding and fine grinding, different grinding wheels need to be replaced at the drive shaft of the grinding machine, so as to carry out rough grinding with a rough grinding wheel and fine grinding with a fine grinding wheel. However, when switching between the two and disassembling and assembling the grinding wheel, it is rather time-consuming and laborious, affecting the processing efficiency and making it inconvenient to quickly switch between rough grinding and fine grinding. In addition, the structure of the handheld grinding machine is relatively simple, and it can only carry out grinding operations, with a single function and poor use effect. Therefore, we propose a handheld multi-functional wooden door grinding device. Summary of the Invention

[0004] The purpose of the present invention is to provide a handheld multi-functional wooden door grinding device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A handheld multi-functional wooden door grinding device, comprising:

[0043] It is convenient for the deformation cavity 403 to deform, so that the rough grinding block 404 extends out from the inside of the fine grinding block 406, thus realizing the switching between fine grinding and rough grinding.

[0044] Preferably, a mounting shaft hole 402 is formed through the middle part of the inner side of the grinding wheel body 401;

[0045] It is convenient for installation and fixation.

[0046] Preferably, the scribing assembly includes a sliding rod 111, a tooth block 112, an adjusting rod 113, a scribing head 114 and a transmission screw 115. The sliding rod 111 is slidably arranged inside the holding rod 5, and one end of the sliding rod 111 penetrates through one end face of the holding rod 5 and is connected with a scribing head 114 for scribing. The transmission screw 115 is rotatably installed at one end inside the holding rod 5, and the transmission screw 115 is matched with the tooth block 112 on the sliding rod 111.

[0058] The working principle and usage process of the present invention: During use, the drive shaft 3 drives the grinding assembly 4 to rotate, and the fine grinding block 406 grinds the surface of the wooden door. When rough grinding is required, the pressing force on the handheld body 1 is increased, so that the elastic member 405 is squeezed and deformed. At this time, the rough grinding block 404 extends from the inside of the fine grinding block 406 to contact the wooden door, and the rough grinding block 404 is used to rough grind the wooden door. When it is necessary to draw a line on the surface of the wooden door, the adjusting rod 113 is rotated to drive the transmission screw rod 115 to rotate. The transmission screw rod 115 cooperates with the tooth block 112 to screw out the sliding rod 111 from the inside of the grip rod 5, adjust the position of the scribing head 114, and then scribe a mark at the position on the surface of the wooden door that needs to be cut or ground through the scribing head 114. Further, the clamping block 14 can be pushed to move by the sliding plate 9, and the clamping block 14 withdraws from the inside of the clamping groove. At this time, the sliding block 12 can slide inside the handheld body 1 to drive the saw blade 7 to extend from the inside of the storage groove 6, and the saw blade 7 can be used to saw off the surface of the wooden door. Similarly, the scale 8 can be extended from the inside of another storage groove 6 to measure the length of the wooden door to be processed.
