Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a but omnipotent sharpedge grinding machine of multiple work piece of adaptability, including sharpedge grinding frame 1 and

clamping device

2, 2 slidable mounting of clamping device are in the side of sharpedge grinding frame 1, sharpedge grinding frame 1's inside fixed mounting has support base 8, support base 8's upper surface one end edge fixed mounting has driving motor 6, driving motor 6's one end center fixedly connected with transmission shaft 3, the even fixed mounting in surface of transmission shaft 3 has whetstone wheel 4, the edge that support base 8's side one end is located driving motor 6 rotates installs starting switch 7, support base 8's top and be located transmission shaft 3 directly over fixed mounting have first gag lever post 5, the bottom side fixed mounting of support base 8 has second gag lever post 9, clamping device 2's inside rotation installs spacing frame 11, spacing frame 11's inside center rotates the joint has spacing sleeve pipe 18, the one end skin weld of spacing sleeve pipe 18 has handle 10, the upper and lower both ends center of spacing frame 11 all welds grafting post 12, the top of grafting post 12 rotates the joint has adjusting screw 13, the outer surface threaded connection of adjusting screw 13 has link 15, the outer surface of second sleeve pipe 20 that the bottom of slip positioning screw hole has set up the plug screw hole 20, the plug screw hole 20 has set up on another sleeve pipe 20.

The connecting frame 15 is slidably sleeved with the outer surface of the first limiting rod 5 through the first sleeve 16, so that the top of the clamping device 2 can be limited.

The second sleeve 20 is sleeved on the bottom of the side face of the sharpening machine frame 1 in a sliding mode through the second limiting rod 9, so that the bottom of the clamping device 2 can be limited and supported.

Adjusting screw 13 rotates the joint through the joint piece 17 of bottom and the top surface center of grafting post 12 to can not drive adjusting screw 13 and rotate in threaded hole 14 inside when can making the grafting post 12 rotate, adjusting screw 13 passes through the inside threaded connection of one end of threaded hole 14 with link 15, thereby when adjusting screw 13 rotates, can drive spacing frame 11 and carry out the lift adjustment in the side of frame 1 of whetting a knife.

The limiting frame 11 is slidably inserted into the sleeving hole 19 through the bottom center inserting column 12, so that the bottom of the inserting column 12 can be supported.

The outer surface of the inserting column 12 at the bottom of the limiting frame 11 is provided with a positioning tooth socket, the center of the side surface of the positioning inserting plate 21 penetrates through the sleeving hole 19 to be inserted into the positioning tooth socket on the outer surface of the inserting column 12, and the positioning effect on the position of the inserting column 12 at the top of the second sleeve 20 can be achieved.

The working principle is as follows: when the tool bit is polished, the tool bit is firstly installed in one end of the limit sleeve 18, when the tool bit is installed, the positioning inserting plate 21 is firstly pulled to slide away from the second sleeve 20, so that the center of the side surface of the positioning inserting plate 21 is separated from the outer surface of the inserting column 12 in the sleeving hole 19, then the handle 10 is pulled to drive the limit frame 11 to rotate by taking the inserting column 12 as the center, so that one end of the limit sleeve 18 is far away from the side surface of the sharpening rack 1, then one end of the tool bit is fixedly inserted into the center of one end surface of the limit sleeve 18, then the handle 10 is pulled to drive the limit frame 11 to reset and rotate, meanwhile, the limit sleeve 18 drives the tool bit at one end to be aligned with the side surface of the sharpening rack 1, then the height of the limit frame 11 is adjusted, so that the limit frame 11 drives the limit sleeve 18 to lift, and ensures that the tool bit in one end of the limit sleeve 18 is aligned with the height of the sharpening wheel 4 on the outer surface of the transmission shaft 3, firstly, the adjusting screw 13 is rotated to go up and down in the threaded hole 14, meanwhile, the adjusting screw 13 can drive the inserting column 12 at the top of the limiting frame 11 to go up and down synchronously through the clamping block 17 at the bottom until the limiting frame 11 drives the cutter head to go up and down to a required height through the limiting sleeve 18, then the inserting column 12 is pulled to drive the first sleeve 16 and the second sleeve 20 at the upper end and the lower end to synchronously slide on the outer surfaces of the first limiting rod 5 and the second limiting rod 9 until the cutter head at one end of the limiting sleeve 18 is aligned with a required sharpening wheel 4, then the starting switch 7 is rotated to start the driving motor 6, the driving motor 6 can drive the transmission shaft 3 at one end to synchronously rotate and run when being started, the transmission shaft 3 can drive the sharpening wheel 4 at the outer surface to synchronously rotate, and then the handle 10 is pulled to control the limiting sleeve 18 to rotate and deflect in the limiting frame 11, simultaneously, the limiting sleeve 18 can drive the cutter head of one end to be close to the outer surface of the cutter grinding wheel 4, thereby the cutter grinding wheel 4 rotating at a high speed can be used for grinding the cutter head, when the cutter head is ground at different angles, the corresponding cutter grinding wheel 4 can be used, excessive rotation of the cutter head can be avoided, meanwhile, the clamping device 2 is transversely pulled to slide transversely on the side surface of the grinding rack 1 as required, the position can be adjusted, a plurality of groups of cutter grinding wheels 4 are installed on the outer surface of the transmission shaft 3, a plurality of groups of grinding wheels can be installed and used simultaneously, thereby the clamping device 2 can be conveniently adjusted, different cutter heads are driven to be in contact with different cutter grinding wheels 4 for grinding, and meanwhile, the adaptability of the universal knife grinder to various workpieces is improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
