[0025] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, the online grinding wheel regrinder 1 is mounted on the grinding head 100 of a horizontal grinding machine. Specifically, the online grinding wheel regrinder includes a support base 11 fixedly connected to the grinding head 100 of the grinding machine. A regrinding assembly 12 is longitudinally slidably connected to the support base 11, and a lifting mechanism 13 is mounted on the support base 11. The lifting mechanism 13 drives the regrinding assembly 12 to slide longitudinally. When the grinding wheel 101 needs regrinding, the lifting mechanism 13 drives the regrinding assembly 12 to descend, so that the regrinding wheel 125 is in contact with the grinding wheel 101 for online regrinding. After regrinding is completed, the lifting mechanism 13 drives the regrinding assembly 12 to rise, so that the regrinding wheel 125 is away from the grinding wheel 101.

[0027] Meanwhile, the lifting mechanism 13 can precisely adjust the lifting position, thereby adjusting the amount of grinding. In a specific embodiment, the lifting mechanism 13 includes a lifting motor 137, a motor base 131, a drive wheel 135, a belt 132, a driven wheel 136, a lead screw 133, and a lead screw seat 134. The motor base 131 and the lead screw seat 134 are fixedly connected to the support base 11. The lifting motor 137 is fixedly mounted on the motor base 131. The lead screw 133 is rotatably connected to the lead screw seat 134. The output end of the lifting motor 137 is fixedly connected to the drive wheel 135. The upper end of the lead screw 133 is fixedly connected to the driven wheel 136. The drive wheel 135 and the driven wheel 136 are connected by a belt 132. The lead screw 133 is threadedly connected to the bracket of the grinding assembly 12. The lifting position of the grinding assembly 12 can be precisely adjusted through the lead screw.

[0028] The grinding assembly 12 includes a bracket, a grinding motor 123, and a grinding wheel 125. The bracket is slidably connected to the support base 11. A rotating shaft 124 is rotatably mounted on the bracket. The grinding motor 123 is fixed to the bracket and is driven by the rotating shaft 124. The grinding wheel 125 is detachably fixed on the rotating shaft 124 and is located above the grinding wheel 101 of the grinding head 100. More specifically, a main pulley 127 is mounted on the grinding motor 123, and an auxiliary pulley 128 is mounted on the left end of the rotating shaft 124. The main pulley 127 and the auxiliary pulley 128 are driven by a belt 126. A longitudinal slide rail 111 is provided on the support base 11, and a slider 123 that cooperates with the longitudinal slide rail is provided on the bracket. The cooperation between the longitudinal slide rail 111 and the slider 123 guides and positions the sliding of the grinding assembly 12.

[0029] The support frame includes a main frame 121 and a support plate 122. One end of the rotating shaft 124 is supported on the main frame 121, and the other end is supported on the support plate 122. A horizontal positioning plate 1221 is bolted to the top surface of the support plate 122, and a vertical positioning plate 1222 is bolted to the side of the support plate 122. The horizontal positioning plate 1221 and the vertical positioning plate 1222 are respectively bolted to the main frame 121. When replacing the grinding wheel 125, the main frame 121 and the support plate 122 need to be disassembled, the rotating shaft 124 needs to be removed, the grinding wheel 125 on the rotating shaft 124 needs to be replaced, and then the rotating shaft 124 and the support plate 122 need to be reinstalled. When the pallet 122 is fixed to the main frame 121, the horizontal positioning plate 1221 and the vertical positioning plate 1222 ensure the horizontal and vertical positions of the pallet 122 relative to the main frame 121, thereby ensuring the positional accuracy of the rotating shaft 124 and the grinding wheel 125.

[0030] The main frame 121 and the support plate 122 are connected by a positioning member 129. The front half of the positioning member 129 is a screw, and the rear half is a pin. The end of the rear half has a threaded hole. The front half of the positioning member is threaded to the main frame, and the pin hole on the support plate mates with the rear half of the positioning member. A bolt is used to connect the support plate to the threaded hole on the positioning member, thus fixing the support plate to the positioning member. When fixing the support plate 122 to the main frame 121, the positioning member 129 is used for initial positioning, and then the horizontal positioning plate 1221 and the vertical positioning plate 1222 are used to position the support plate 122. This method is convenient and provides accurate positioning.

[0031] A front bearing 1241 and a rear bearing 1242 are provided on the rotating shaft 124. The outer ring of the front bearing 1241 is fixedly connected to the main frame 121, and the outer ring of the rear bearing 1242 is fixedly connected to the support plate 122. A grinding wheel 125 is located between the front bearing 1241 and the rear bearing 1242. A front retaining ring 1243 and a rear retaining ring 1244 are provided on the rotating shaft 124. The grinding wheel 125 is located between the front retaining ring 1243 and the rear retaining ring 1244, and is clamped and fixed by the front retaining ring 1243 and the rear retaining ring 1244. A stepped annular surface is formed on the rotating shaft, and the stepped annular surface is located between the front retaining ring 1243 and the front bearing 1241, and the stepped annular surface is in close contact with the front retaining ring 1243. A locking ring 1245 is installed on the rotating shaft 124. The locking ring 1245 has a threaded through hole, and a set screw is threaded into the threaded through hole. The set screw tightens the rotating shaft 124, thereby fixing the locking ring 1245 on the rotating shaft 124. The locking ring 1245 is located between the rear retaining ring 1244 and the rear bearing 1242, and the locking ring 1245 is in close contact with the rear retaining ring 1244. The locking ring 1245 and the stepped annular surface lock the positions of the front retaining ring 1243, the rear retaining ring 1244, and the grinding wheel 125. A front bearing sleeve 1247 and a rear bearing sleeve 1246 are installed on the rotating shaft 124. The front bearing sleeve 1247 is fixedly connected to the main frame 121, and the rear bearing sleeve 1246 is fixedly connected to the support plate 122. The front bearing sleeve 1247 is located between the stepped annular surface and the front bearing 1241, and the rear bearing sleeve 1246 is located between the locking ring 1245 and the rear bearing 1242. Preferably, the rear bearing sleeve 1246 wraps around and fixes the rear end of the rotating shaft 124, and the rear bearing sleeve 1246 and the rotating shaft 124 are fixedly connected by bolts. The inner ring of the rear bearing 1242 is fixed on the rear bearing sleeve 1246. A bearing cover 1248 is installed on the rear end face of the support plate 122 to seal the rear bearing 1242. The front bearing sleeve 1247, the rear bearing sleeve 1246, and the bearing cover 1248 reliably position and seal the front bearing 1241 and the rear bearing 1242. The front retaining ring 1243 and the rear retaining ring 1244 reliably limit the grinding wheel 125.
