Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment, specifically a dual-head grinding device. Background Technology
[0002] Sanding is a crucial step in woodworking, as it is necessary to sand the surface and edges of the wood smooth to prevent splinters from affecting the quality.
[0003] Current grinding equipment is usually equipped with only a single grinding tool, such as a single grinding wheel or grinding belt. When it is necessary to perform two different precision grinding operations on the workpiece, such as coarse grinding and fine grinding, it is often necessary to change different grinding equipment or grinding tools. This not only increases production costs but also reduces production efficiency. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, this utility model provides a dual-head grinding device.
[0005] The technical solution adopted by this utility model is as follows:
[0006] A dual-head grinding device includes a base plate, a mounting frame fixedly connected to the top front side of the base plate, and a dual-head motor fixedly mounted on the top of the mounting frame. A dovetail groove is formed in the middle of the top rear side of the base plate, extending front and rear. A tensioning frame is located on the top of the base plate, behind the mounting frame. The lower part of the tensioning frame is straight, extending upwards to the left and right sides. The left and right sidewalls of the tensioning frame are right-angled triangular plates, with the right-angled sides of the sidewalls located at one end of the top of the base plate opposite the dual-head motors. A limiting block is fixedly connected to the middle of the bottom of the tensioning frame, inside the dovetail groove, and slidably engaged with it. Three... The top corners are all rotatably connected by shafts. The left and right ends of the three shafts extend through the outer wall of the tensioning frame. The upper shaft is flush with the output shaft of the dual-head motor. The outer walls of both ends of each shaft and the outer walls of the two output shafts of the dual-head motor are fixedly fitted with pulleys. The outer walls of the four pulleys on the left and the four pulleys on the right are respectively slidably fitted with coarse and fine grinding belts. The lower top of the tensioning frame is fixedly connected to a support base. The top of the support base is at the same level as the top of the coarse and fine grinding belts. Adjustment grooves are opened on the left and right sides of the top of the base plate. The adjustment grooves are located on the left and right sides of the tensioning frame. The lower left and right side walls of the tensioning frame are fixedly connected to a limiting mechanism.
[0007] The two output shafts of the dual-head motor are respectively fixedly fitted with a coarse grinding wheel and a fine grinding wheel.
[0008] The limiting mechanism includes a fixed plate, two fixed plates are respectively fixedly connected to the lower two outer walls of the tensioning frame. There is a slider below the fixed plate. The slider is above the adjustment groove. The bottom of the slider is slidably engaged with the inner side of the adjustment groove. The top of the slider is vertically fixedly connected to a threaded column. The threaded column passes through the fixed plate. The bottom of the threaded column is slidably engaged with the adjustment groove. The upper outer wall of the threaded column is threaded with a locking nut. The bottom of the locking nut abuts against the top of the fixed plate.
[0009] The beneficial effects of this utility model are:
[0010] This utility model is equipped with a coarse grinding belt, a fine grinding belt, a coarse grinding wheel, and a fine grinding wheel. In actual grinding operations, coarse or fine grinding methods can be flexibly selected according to different grinding requirements of the workpiece. The grinding belt and grinding wheel can be used simultaneously or alternately to meet diverse grinding requirements, improve the versatility and applicability of the equipment, and reduce the time for changing grinding tools.

The top corners are all rotatably connected to the rotating shaft 7. The left and right ends of the three rotating shafts 7 extend through the outer wall of the tensioning frame 5. The upper rotating shaft 7 is flush with the output shaft of the double-head motor 3. The outer walls of both ends of each rotating shaft 7 and the outer walls of the two output shafts of the double-head motor 3 are fixedly sleeved with pulleys 8. The outer walls of the four pulleys 8 on the left and the four pulleys 8 on the right are respectively slidably sleeved with the coarse grinding belt 9 and the fine grinding belt 10. The lower top of the tensioning frame 5 is fixedly connected to the support base 11. The top of the support base 11 is at the same level as the top of the coarse grinding belt 9 and the fine grinding belt 10. The top left and right sides of the base plate 1 are provided with adjustment grooves 12. The adjustment grooves 12 are located on the left and right sides of the tensioning frame 5. The middle of the lower left and right side walls of the tensioning frame 5 are fixedly connected to the limiting mechanism.
[0018] The two output shafts of the head motor 3 are respectively fixedly sleeved with the coarse grinding wheel 17 and the fine grinding wheel 18.
[0019] The limiting mechanism includes a fixed plate 13. Two fixed plates 13 are respectively fixedly connected to the lower outer walls of the tensioning frame 5. A slider 14 is located below the fixed plate 13. The slider 14 is located above the adjustment groove 12.
