[0024] like Figure 1-6 As shown, the utility model provides a floating grinding mechanism, which includes a fixed module 20, a mold module 10, a floating module 30 and a limiting module 40. The floating module 30 is fixedly mounted on the fixed plate of the fixed module 20 by bolts, the mold module 10 is mounted on the sliding connection 302 of the floating module 30 by bolts, the upper part of the limiting module 40 is connected to the fixed module 20, and the lower part of the limiting module 40 is connected to the motor base 102 of the mold module 10. The lower part of the limiting module 40 is connected to the motor base 102 by bolt connection, welding or clamping. The floating grinding mechanism has a simple structure. It is used to effectively limit the lowest point of the surface to be ground, and uses all or part of the weight of the grinding tool module 40 as gravity to grind the surface of the workpiece to be ground to eliminate burrs, rust, etc. during the grinding process of the workpiece to be ground with curved surfaces, inclined surfaces and special-shaped surfaces. The grinding surface generates a reverse force, causing the grinding tool module to float upward, driving the floating component to slide upward, and realizing the grinding of the special-shaped surface of the workpiece.

[0025] The limiting module 40 includes a limiting partition 404, a screw rod 401, a limiting block 402 and a connecting piece 407. The limiting block 402 is placed on the limiting partition 404. A through hole is opened at the corresponding position of the limiting block 402 and the limiting partition 404. The through hole enables the lower end of the screw rod 401 to pass through the through hole and be movably connected to the connecting piece 407. The connecting piece 407 is connected to the motor base 102. The connecting piece 407 has an internal threaded through hole. The screw rod 401 is inserted into the internal threaded through hole on the connecting piece 407. The limit block 404 is provided with a through hole and a guide hole, and the limit block 402 is also provided with a screw through hole. On both sides of the screw through hole, there are through holes corresponding to the guide holes on the limit partition 404. One end of the limit pin 405 passes through the through hole and is fixed on the limit block 402. The other end of the limit pin 405 passes through the guide hole on the limit partition 404. The rotation of the limit block 404 is limited by the limit pin 405. The top of the screw rod 401 is connected to a handle for rotating the screw rod 401. By rotating the handle, the limit length of the screw rod 401 can be extended or shortened, so that the lowest end of the grinding surface can be adjusted according to actual needs. A limit pin 405 is also provided on the limit block 402. One end of the limit pin 405 is connected to the limit block 402, and the other end passes through the guide hole on the limit partition 404. The screw rod 401 can rotate in the limit block 402, and the screw rod 401 cannot be in the limit block 402. When the screw rod 401 moves up and down, it rotates in the limit block 402 when adjusting the lower limit position. A locking screw 406 is also provided on the limit block 402. The locking screw 406 can prevent the screw rod 401 from rotating when the mold module 10 vibrates during operation. When grinding the workpiece, the lowest point of the lower limit is set, the limit block contacts the limit partition, and the limit partition supports the limit block. During the grinding work, the mold module changes with the height of the surface to be ground, and the distance between the limit block and the limit partition will also increase or decrease. Figure 1-6 shown.

[0026] The floating module 30 includes a guide rail 301 and a sliding connector 302. The sliding connector 302 is installed on the guide rail 301 and can slide up and down on the guide rail 301. The mold module 10 is installed on the sliding connector 302. The weight of the mold module 10 is used as the downward gravity. When the surface to be ground is uneven, the lowest point is set. During grinding, as the height of the surface to be ground increases, the reverse force of the grinding surface pushes the mold module 10 to float up. The sliding connector 301 slides up and down on the guide rail 301 as the mold module 10 floats up and down, so that the grinding surface of the grinding piece and the grinding surface of the workpiece 80 to be ground can maintain contact, thereby realizing the grinding of the special-shaped surface of the workpiece.

[0027] The fixed module 20 includes a fixed plate 201 and a tension adjustment member 202, which is mounted on the fixed plate 201. The tension adjustment member 202 can be moved up and down on the fixed plate 201 and is connected to the mold module 10 via an elastic member, which is a spring 203 or a silicone elastic member. A slide is provided on the fixed plate 201, and the tension adjustment member 202 is mounted on the slide. The tension adjustment member 202 is a bolt that can be adjusted in position within the slide. The tension adjustment member 202 is locked at the bottom of the slide, which can increase the pressure of the mold module on the workpiece being ground. Figure 3 、 5 The tension adjustment member 202 is locked on the upper part of the slideway to reduce the pressure of the grinding tool module on the grinding workpiece. Figure 1 、 2 Similarly, changing the position of the adjustment rod on the motor base above or below the motor base can also reduce or increase the pressure of the grinding tool module on the grinding workpiece.

[0028] The grinding tool module 10 includes a motor base 102, a motor 101 and a grinding piece 103. The motor 102 is fixedly installed on the motor base 102 by bolts. The grinding piece 103 is locked on the rotating shaft of the motor 101. The motor 101 drives the grinding piece 103 to rotate to grind the surface to be ground. One end of the elastic member is connected to the fixed plate 201, and the other end is connected to the adjusting rod 104 of the motor base 102. According to the pressure requirement of the grinding workpiece, the tension adjusting member 202 or the adjusting rod position on the motor base is moved, and the positive or reverse tension of the elastic member is used to enable the grinding tool module 10 to grind the workpiece to be ground.

[0029] The adjusting rod 104 is arranged on the sliding groove of the motor base 102. The nut of the adjusting rod 104 can slide up and down in the sliding groove, and then the nut is locked and fixed.

[0030] When grinding an inclined or flat workpiece, use a common output shaft motor and use the lower end of the grinding piece to grind the workpiece to remove burrs or rust on the surface, making the surface of the workpiece smooth. Figure 1 、 2 , 6; When the workpiece is concave and convex, use the reversing shaft motor, install the grinding piece on the machine shaft, and grind the workpiece using the circumferential surface of the grinding piece to eliminate burrs or rust on the concave and convex surface, so that the surface of the workpiece becomes smooth, such as Figure 3 、 4 As shown in Figure 5, before grinding the workpiece, it is necessary to determine what kind of motor is needed to drive the grinding piece for grinding. When grinding concave and convex surfaces, only concave and convex surfaces composed of large arc surfaces can be ground, and large special-shaped surfaces that are bent into a V-shaped connection cannot be ground.

[0031] Another object of the present utility model is to provide a grinding device, comprising a floating grinding mechanism, a workbench, a moving mechanism, a workpiece fixing mechanism to be ground, and a controller, wherein the moving mechanism is arranged on the workbench, the floating grinding mechanism is arranged on the moving mechanism, the workpiece fixing mechanism to be ground is arranged on the workbench and placed below the floating grinding mechanism, and the control end of the moving mechanism and the control end of the floating grinding mechanism are respectively connected to the output end of the controller.

[0032] The working platform, moving mechanism, fixing mechanism and controller in the grinding device are all described in detail in the applicant's previous patent application for a knife sharpener. In this application, only modifications are made, so they will not be described in detail.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
