Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel polishing, in particular to a grinding wheel end face polishing device. Background Art

[0002] Grinding wheels are also called bonded abrasives. Grinding wheels are bonded abrasives that are bonded by a binder into a certain shape (mostly round with a through hole in the center) and have a certain strength. They are generally composed of abrasives, binders, and pores. These three parts are often called the three elements of bonded abrasives. According to the different classifications of binders, common ones are ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels. Grinding wheels are the most widely used and widely used type of abrasives. When used, they rotate at high speed and can perform rough grinding, semi-finishing grinding, and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane, and various surfaces of metal or non-metal workpieces.

[0003] When grinding with existing grinding wheels, generally only one grinding wheel is used to grind the material to be ground with its end face. After grinding one side, the material can be turned over to grind the other side, which is time-consuming and laborious. In addition, the grinding wheel is generally fixed and installed by bolts. When the grinding wheel needs to be replaced, specific tools such as screwdrivers must be used for disassembly. The disassembly process is relatively complicated and tedious, and it takes a lot of time, which is not conducive to the rapid installation and disassembly of the grinding wheel. Therefore, a grinding wheel end face grinding device with double grinding wheels that can be quickly disassembled is needed. Utility Model Content

The displacement of the sliding rod 34 will drive the first grinding wheel 38 to move closer to or away from the second grinding wheel 319. After adjusting to a suitable position, the limit switch on the telescopic rod 313 is pressed down to start the motor 36 to rotate. The rotation of the motor 36 will drive the first grinding wheel 38 and the second grinding wheel 319 to rotate at the same time. The first grinding wheel 38 and the second grinding wheel 319 can grind both sides of the workpiece 2 by rotating at the same time, without flipping the workpiece 2 back and forth, saving time and effort.

[0026] Further, see Figure 1 A handle 320 is installed on the screw rod 32, and a cushion is arranged on the handle 320. The arrangement of the handle 320 can make it more convenient to rotate the screw rod 32, and the cushion arranged on the screw rod 32 makes it more comfortable when touched by hand.

[0027] Further, see Figure 1 A horizontal bar 321 is installed on the base 1, and a sliding groove is opened in the horizontal bar 321. The bottom of the slide bar 34 is installed on the slider 322, and the slider 322 is slidably installed in the sliding groove of the horizontal bar 321.

[0028] Further, see Figure 2 A limiter 323 is installed on the second rotating shaft 318 , and the limiter 323 is installed on the outside of the third support rod 317 . The setting of the limiter 323 can prevent the second rotating shaft 318 from rotating out of the third support rod 317 .

[0029] Embodiment 2:

[0030] like Figure 4 As shown, based on the embodiment 1, the first grinding wheel 38 and the second grinding wheel 319 can be quickly installed and removed by setting the fixed disassembly assembly.

[0031] The fixed disassembly assembly includes a fixed box 41, which is mounted on the second rotating shaft 318. A slide plate 42 is installed in the fixed box 41, a fixed block 43 is installed at the bottom of the slide plate 42, a fixed spring 44 is installed in the fixed box 41, and the other end of the fixed spring 44 is installed on the fixed block 43. A fixed bar 45 is arranged in the fixed box 41, and the fixed bar 45 is installed on the second grinding wheel 319. A screw hole is opened on the fixed box 41, and a fixing screw 46 is installed in the screw hole. When the second grinding wheel needs to be replaced, 319, first twist the knob 48 by hand to move the fixing screw 46 away from the fixing bar 45, and pull the second grinding wheel 319 by hand so that the fixing bar 45 is pulled out of the fixing block 43 to replace the second grinding wheel 319. When the second grinding wheel 319 needs to be fixed, push the fixing bar 45 into the fixing block 43, and twist the knob 48 in the opposite direction to make the fixing screw 46 contact and squeeze the fixing bar 45 to fix the second grinding wheel 319. This operation can quickly install and disassemble the first grinding wheel 38 and the second grinding wheel 319, saving time.

[0032] Further, see Figure 4 A fixing block 43 is installed at the bottom of the slide plate 42. There are two fixing blocks 43. Both fixing blocks 43 are square in shape. The setting of the two fixing blocks 43 can clamp the fixing bar 45. The square setting can make the clamping of the fixing bar 45 more stable when the second grinding wheel 319 rotates.

[0033] Further, see Figure 4 A cross bar 47 is installed in the base 1, and the slide plate 42 is slidably installed on the cross bar 47. The setting support of the cross bar 47 restricts the slide plate 42, so that the slide plate 42 can only move on the cross bar 47.

[0034] Further, see Figure 4A knob 48 is mounted on the fixing screw 46, and the length of the knob 48 is one to two centimeters. The setting of the knob 48 can make it easier to rotate the fixing screw 46, and the length of the knob 48 is one to two centimeters, which can save effort when twisting the knob 48 by hand.

[0035] The working principle of the utility model is as follows: when in use, the workpiece 2 is first placed between the first rotating shaft 37 and the second grinding wheel 319, and the handle 320 is turned to drive the screw rod 32 to rotate. The rotation of the screw rod 32 will drive the sliding rod 34 to move. The movement of the sliding rod 34 drives the support block 35 to move. The displacement of the support block 35 drives the motor 36 to move. The displacement of the motor 36 drives the first grinding wheel 38 to move. After adjusting to a suitable position, the limiter on the telescopic rod 313 is pressed down, and the motor 36 is started. The motor 36 drives the first rotating shaft 37 to rotate. The rotation of the first rotating shaft 37 drives the first grinding wheel 38 to rotate. The rotation of the first rotating shaft 37 will also drive the first pulley 39 to rotate. The rotation of the first pulley 39 drives the first belt 310 to rotate. The rotation of the first belt 310 drives the second pulley 311 to rotate. The rotation of the second pulley 311 drives the telescopic rod 313 to rotate. The rotation of the telescopic rod 313 drives the third pulley 314 to rotate. The rotation of the third pulley 314 drives the second belt 3 15 rotates, the second belt 315 rotates to drive the fourth pulley 316 to rotate, the fourth pulley 316 rotates to drive the second rotating shaft 318 to rotate, the second rotating shaft 318 rotates to drive the second grinding wheel 319 to rotate, the first grinding wheel 38 and the second grinding wheel 319 rotate at the same time to grind both sides of the workpiece 2, there is no need to flip the workpiece 2 back and forth, saving time and effort, when the second grinding wheel 319 needs to be replaced, first twist the knob 48 by hand, the twisting of the knob 48 will move the fixing screw 46 away from the fixing bar 45, due to the action of the fixing block 43 and the fixing spring 44, the second grinding wheel 319 is pulled by hand to make the fixing bar 45 pull out of the fixing block 43 to replace the second grinding wheel 319, when the second grinding wheel 319 needs to be fixed, the fixing bar 45 is pushed into the fixing block 43, and the knob 48 is twisted in the opposite direction to make the fixing screw 46 contact and squeeze the fixing bar 45 to fix the second grinding wheel 319, so that the second grinding wheel 319 can be quickly installed and removed by operation, saving time.
