DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 The utility model provides a technical solution: a grinder with an adjustable clamp, comprising a base 1, an operation panel 7 and a hand wheel 22, an operation table 2 is installed on the top of the base 1, a magnetic suction cup 3 is installed on the top of the operation table 2, a sharpener 4 is arranged on the top of the magnetic suction cup 3, a connecting frame 5 is installed on one side of the sharpener 4, an operation host 6 is installed on one side of the connecting frame 5, the operation panel 7 is installed on one side of the operation host 6, and the hand wheel 22 is installed on one side of the operation table 2.

[0025] A clamp seat 8 is adsorbed on the top of the magnetic suction cup 3, a rotating shaft 9 is installed in the middle of the clamp seat 8 through a groove, a clamp body 10 is installed on the top of the rotating shaft 9, a gear 11 is installed on the outside of the rotating shaft 9, a plug-in clamp rod 12 is installed on one side of the gear 11, a movable spring 13 is installed between the clamp rod 12 and the groove of the clamp seat 8, a movable rod 14 is provided on the side of the clamp rod 12 away from the gear 11 through an inclined surface, a pull rod 15 that passes through the clamp seat 8 is connected to one side of the movable rod 14, and a sliding structure is formed between the movable rod 14 and the clamp seat 8 through a slide groove.

[0026] When the clamp needs to be adjusted during use, the pull rod 15 is pulled to one side, and the pull rod 15 drives the movable rod 14 to move, so that the inclined groove on one side of the movable rod 14 is aligned with the clamping rod 12. At this time, the movable rod 14 releases the squeeze on the clamping rod 12, and the clamping rod 12 is reset by the movable spring 13. The inclined surface at one end of the clamping rod 12 is connected to the inclined groove of the movable rod 14. At the same time, the other side of the clamping rod 12 will be separated from the gear 11 outside the rotating shaft 9, and the limit of the gear 11 by the clamping rod 12 can be released, so that the gear 11 can rotate normally. At this time, you only need to rotate the clamp body 10 to make the clamp body 10 rotate through the rotating shaft 9 at the bottom, so The direction of the clamp on the top can be adjusted to facilitate multi-angle grinding of the workpiece without disassembling and rearranging the workpiece; when the clamp body 10 needs to be fixed, it is only necessary to push the pull rod 15 in the opposite direction, so that the pull rod 15 drives the movable rod 14 to move in the opposite direction. Under the action of the inclined groove of the movable rod 14 and the inclined surface of the clamping rod 12, the movable rod 14 can squeeze the clamping rod 12 to one side, and make one side of the clamping rod 12 dock with the gear 11, so as to limit the position of the gear 11. The gear 11 cannot rotate, so that the rotating shaft 9 cannot drive the clamp body 10 to rotate, so that the position of the clamp body 10 can be fixed, and the stability of the entire clamp body 10 is ensured.

[0027] See also Figures 1 to 4 It can be seen that when in use, the angle of the fixture can be adjusted according to the grinding requirements of the workpiece, so that the workpiece can be ground at multiple angles.

[0028] Both sides of the magnetic suction cup 3 are connected to sliders 16 through sliding grooves, one side of the slider 16 is connected to a rotating rod 17 through a rotating shaft, a telescopic spring 18 is installed inside the rotating rod 17 through a groove, a telescopic rod 19 that penetrates the rotating rod 17 is installed on one side of the telescopic spring 18, a connecting rod 20 is installed between the two groups of telescopic rods 19, a cleaning plate 21 is installed at the bottom of the connecting rod 20, and the telescopic rod 19 forms a rotating structure with the rotating rod 17 through the telescopic spring 18.

[0029] During specific implementation, when the grinder with the adjustable clamp needs to clean the surface of the magnetic suction cup 3, the telescopic rod 19 can be pulled to one side so that the telescopic rod 19 is stretched out from one side of the rotating rod 17. At this time, the rotating rod 17 can be rotated through the rotating shaft so that the rotating rod 17 rotates the connecting rod 20 to the top of the magnetic suction cup 3 through the telescopic rod 19, and then the telescopic rod 19 is released. The telescopic rod 19 will be retracted into the inside of the rotating rod 17 through the telescopic spring 18, and at the same time, the cleaning plate 21 at the bottom is driven to move downward through the connecting rod 20, so that the bottom of the cleaning plate 21 is in contact with the magnetic suction cup 3. At this time, the connecting rod 20 can be pulled so that the connecting rod 20 slides along the slide groove of the magnetic suction cup 3 through the sliders 16 on both sides, and drives the cleaning plate 21 to move, and the surface of the magnetic suction cup 3 can be cleaned through the cleaning plate 21, thereby conveniently and quickly cleaning the surface of the magnetic suction cup 3;

[0030] On the contrary, the cleaning plate 21 can be pulled to one side by the slider 16, and then the telescopic rod 19 can be pulled again to move the telescopic rod 19 out of the groove of the rotating rod 17, and then the connecting rod 20 can be rotated in the opposite direction, so that the connecting rod 20 drives the cleaning plate 21 to rotate to the side of the magnetic suction cup 3, and the cleaning plate 21 is supported by the protrusions on the side of the magnetic suction cup 3, so as not to affect the normal use of the magnetic suction cup 3.

[0031] See also Figure 1 , Figure 5 and Figure 6 It can be seen that when in use, the cleaning plate 21 can be rotated to the top of the magnetic suction cup 3 according to the use requirements, and then the cleaning plate 21 is driven to move by the slider 16. At this time, the surface of the magnetic suction cup 3 can be cleaned, thereby conveniently and quickly cleaning the magnetic suction cup 3.

[0032] To sum up, when using the grinder with adjustable clamp, the entire grinder can be placed in a stable position through the base 1, and then the magnetic workpiece to be grinded can be placed on the magnetic suction cup 3, and the magnetic suction cup 3 can be magnetized. After magnetization, the magnetic workpiece can be fixed. When the workpiece to be grinded is not magnetic, the clamp body 10 is needed to be used, and the clamp body 10 is fixed by the magnetic suction cup 3, and then the clamp body 10 can fix the non-magnetic workpiece. After the fixing is completed, the control panel can be started, so that the control panel controls the connecting frame 5 to move through the operating host 6, so that the connecting frame 5 drives the grinder 4 to move. After the grinder 4 contacts the workpiece, the grinder 4 can be started to move through the electric control cabinet and the wire on one side. At this time, the surface of the workpiece can be grinded, and the grinding position can also be controlled by the hand wheel 22. This is the prior art and will not be elaborated on here.
