[0031] 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.

[0032] See also Figure 1-8 The utility model provides an embodiment: a refrigerator handle grinding device, including a fixed plate 3, a chassis 5 and a grinding motor 9, a hydraulic cylinder 6 and a pressure pump 7 are fixedly installed inside the chassis 5, and the pressure pump 7 is connected to the inlet and outlet of the hydraulic cylinder 6 through a hydraulic pipe; the operation of the hydraulic cylinder 6 and the pressure pump 7 is mainly controlled by a hydraulic controller 12, and the control principle is essentially the same as that of the prior art.

[0033] The hydraulic rod 601 of the hydraulic cylinder 6 extends out of the chassis 5 and is connected to the bottom of the fixed plate 3. A grinding table 4 is fixedly installed on the top of the chassis 5. A grinding motor 9 is fixedly connected to the upper surface of the fixed plate 3. The main shaft 901 of the grinding motor 9 passes through the fixed plate 3 and is connected to the grinding wheel 11. The grinding table 4 is located directly above the grinding wheel 11.

[0034] The operation of the grinding motor 9 is mainly controlled by the motor controller 13, which mainly controls the turning on and off of the grinding motor 9. The motor controller 13 is also electrically connected to the flashing light 8. When the grinding motor 9 is powered on, the flashing light 8 will light up at the same time, making it easier for users to judge the operating status of the grinding motor 9. The control principle of the motor controller 13 on the grinding motor 9 and the flashing light 8 is essentially the same as that of the prior art.

[0035] An L-shaped connecting frame 1 is also fixedly connected to one side of the upper surface of the fixed plate 3, and a grinding motor 2 is fixedly installed on the L-shaped connecting frame 1; grinding wheels 202 are installed on both sides of the grinding motor 2, and an eye protection baffle 201 is installed on the outer shield of the grinding wheel 202 to block the strong light generated during the grinding process.

[0036] The workpiece is placed on the grinding table 4, and the height of the limit support table 10 is adjusted to adapt to the grinding height of the workpiece; then the grinding motor 9 is started; the pressure pump 7 is started to provide hydraulic pressure for the hydraulic cylinder 6, and the hydraulic rod 601 of the hydraulic cylinder 6 descends, grinding the workpiece while descending until one end of the limit support table 10 presses against the top end surface of the chassis 5, at which time the grinding is finished.

[0037] A small table is provided on the outer shield of the grinding wheel 202. When grinding a small area or other angles, the workpiece can be placed on the small table, which is convenient for grinding directly with the grinding wheel 202. The eye shield can block the strong light generated during the grinding process. The utility model preferably uses a transparent material to make the eye shield more convenient for the operator to grind.

[0038] It also includes a limited support platform 10, which is composed of a fixed nut seat 101 and a movable screw seat 102. One end face of the fixed nut seat 101 is fixed on the lower surface of the fixed plate 3, and the screw hole at one end of the fixed nut seat 101 is threadedly connected with the screw rod of the movable screw seat 102; the hydraulic rod 601 passes through the movable screw seat 102 and the fixed nut seat 101 in sequence and is fixedly connected with the bottom of the fixed plate 3. In order to facilitate the rotation of the movable screw seat 102, there is a clearance fit between the hydraulic rod 601 and the movable screw seat 102. By rotating the movable screw seat 102, the height of the limited support platform 10 is adjusted to achieve different descending heights of the grinding motor 9.

[0039] In order to ensure the stability between the fixed nut seat 101 and the movable screw seat 102, and also to prevent the two components from being displaced, at least one pin hole 1011 is provided on the outer wall of the fixed nut seat 101, and an internal thread is provided in the pin hole 1011. After the lateral limit screw 16 is threadedly connected with the internal thread of the pin hole 1011, it is tightly pressed against the screw rod of the movable screw seat 102.

[0040] The outer wall of the fixing nut seat 101 of the utility model is provided with two pin holes 1011, and the two pin holes are symmetrically arranged.

[0041] In order to further secure the fixed nut seat 101 and the movable screw seat 102 and prevent the two components from being damaged during long-term use, a buffer washer 17 is provided between the fixed nut seat 101 and the movable screw seat 102. The buffer washer 17 is composed of a female semi-cylindrical washer 102a and a male semi-cylindrical washer 102b. The female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b together hold the screw of the movable screw seat 102. The buffer washer 17 of the utility model is made of rubber material. Of course, for the sake of grinding accuracy and stability of the mechanism, a relatively hard buffer washer 17 is preferably used.

[0042] Examples of the connection between the female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b are as follows: both end surfaces of the female semi-cylindrical washer 102a are provided with plunger holes 102a1, and the plunger holes 102a1 are provided with boss holes 102a2; both end surfaces of the male semi-cylindrical washer 102b are provided with plungers 102b1 matching the plunger holes 102a1, and the outer wall of the plunger 102b1 is provided with bosses 102b2 matching the boss holes 102a2. When the plunger 102b1 is nested in the plunger hole 102a1, the boss 102b2 is also nested in the boss hole 102a2. At this time, the female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b are combined to hold the screw of the movable screw seat 102. When the buffer washer 17 is squeezed, the protruding column 102b2 may be squeezed and deformed. This deformation trend will make the connection between the female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b more secure.

[0043] Of course, in order to simplify the connection structure between the female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b, an example can also be: an iron sheet is provided on the connection surface of the female semi-cylindrical washer 102a, and a magnet is provided on the connection surface of the male semi-cylindrical washer 102b. The iron sheet of the female semi-cylindrical washer 102a is attracted to the magnet of the male semi-cylindrical washer 102b. At this time, the female semi-cylindrical washer 102a and the male semi-cylindrical washer 102b are combined to hold the screw of the movable screw seat 102.

[0044] By hingedly installing a door 15 at the front end of the chassis 5, it is more convenient for users to inspect and maintain the interior of the chassis 5 during use. By providing heat dissipation windows 14 on the surface of the chassis 5 on both sides of the door 15, the air inside can be better circulated, thereby effectively preventing the device from being damaged due to overheating. A transparent window 1501 is fixedly installed on the surface of the door 15, which makes it more convenient for users to observe the interior of the chassis 5 without opening the door 15, thereby making it more convenient for users to use the device. A handle 1502 is fixedly installed on one side of the transparent window 1501, which is convenient for operators to open and close the door 15.

[0045] Universal wheels 502 are fixedly installed at the bottom of the chassis 5, and adjustable feet 501 are fixedly installed on both sides of the universal wheels 502. If the device needs to be moved, the height of the adjustable feet 501 can be shortened until the adjustable feet 501 are suspended in the air, at which time the universal wheels 502 mainly play a supporting role, and the operator can move the device at will. If the device is fixed, the height of the adjustable feet 501 can be extended until the universal wheels 502 are suspended in the air, at which time the adjustable feet 501 mainly play a supporting role, thereby playing a positioning role, and at the same time, it can avoid the phenomenon that the grinding motor 2 is displaced due to the uneven ground where the grinding motor 2 is located when the grinding motor 2 is placed.
