Description

Technical Field

[0001] The utility model relates to the field of display brackets, in particular to a display bracket polishing device. Background Art

[0002] A monitor stand is a product that can fix monitors, laptops or tablets, etc. It can help solve various technical problems encountered by people when operating computers at home or in commercial offices. Its ergonomic design can prevent health problems caused by work fatigue, improve work efficiency, and create an ideal space for living and working. The surface of the monitor stand needs to be polished during the production process to reduce the surface roughness of the monitor stand and obtain a bright and smooth surface.

[0003] After searching, a utility model bracket polishing device for sheet metal production with publication number CN219152487U was found. It includes a shell, one side of the outer wall of the shell is fixedly connected to a first motor, and the output end of the first motor is transmission-connected to a gear. The utility model processes sheet metal by using the first motor, the second motor and the third motor in coordination, which not only improves the work efficiency, but also polishes the sheet metal at multiple angles; at the same time, the clamping block generates magnetic force through the electromagnet, so that the clamping block absorbs the waste generated during polishing, which not only cleans the sheet metal waste, but also facilitates the recovery of sheet metal waste.

[0004] In the above patent, many of the existing display brackets are polished manually, but manual polishing not only increases the labor intensity of workers, but also delays the polishing time.

A polishing disc 14 is fixedly installed on the output end of the servo motor 13.

[0036] The dust suction mechanism 15 is installed on one side of the support frame 11 and is used to absorb debris during polishing. By pulling the connecting rod 601 and the handle 602, the limit block 603 outside the connecting rod 601 is disengaged from the limit groove 5 in the movable frame 4, and then the handle 602 is rotated to drive the connecting rod 601 and the connecting column 605 at one end and the clamping mechanism 7 to rotate. After rotating to 180 degrees, the handle 602 is released, and the limit block 603 is clamped in the limit groove 5 in the movable frame 4 through the rebound ability of the spring 604 outside the connecting rod 601, thereby completing the rotation of the display bracket.

[0037] like Figure 1 and Figure 2 As shown, a first drive motor 2 is fixedly provided on one side of the base 1, a first screw rod 3 is fixedly installed on the output end of the first drive motor 2, a movable frame 4 is movably provided outside the first screw rod 3, two groups of first screw rods 3 are provided, and the thread tapping directions of the two groups of first screw rods 3 are opposite. The first drive motor 2 is used to drive the first screw rod 3 to rotate, so that the two groups of movable frames 4 move relative to each other, thereby adjusting according to the length of the display bracket.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the rotating mechanism 6 includes a connecting rod 601, a handle 602, a limit block 603, a spring 604, and a connecting column 605. The connecting rod 601 is movably connected to one side of the movable frame 4. The handle 602 is fixedly installed at one end of the connecting rod 601. The limit block 603 is fixedly installed on the outside of one side of the connecting rod 601. An inner cavity is opened inside the movable frame 4. A spring 604 is arranged on the outside of the connecting rod 601 and the inside of the inner cavity. The other end of the connecting rod 601 is fixedly installed with a connecting column 605. By pulling the handle 602, the connecting rod 601 and the clamping mechanism 7 at one end are extended and retracted, so that the connecting rod 601 outside the connecting rod 601 is separated from the contact limit of the movable frame 4, and then rotated to the required position, and then the handle 602 is released to utilize the rebound effect of the spring 604 to clamp the limit block 603 in the limit groove 5 on the movable frame 4, so as to limit and fix the entire clamping mechanism 7.

[0039] like Figure 3 As shown, the limit blocks 603 are arranged in four groups, and the four groups of limit blocks 603 are distributed in a circular array outside the connecting rod 601. The limit blocks 603 are used in conjunction with the limit grooves 5 on one side of the movable frame 4. By setting four groups of limit blocks 603, rotation and limiting can be performed according to four angles, making it convenient for the staff to polish the display bracket.

[0040] like Figure 1 , Figure 2 and Figure 4As shown, the clamping mechanism 7 includes a connecting plate 701, a slide groove 702, a clamping block 703, an anti-slip pattern 704, a screw 705, and a handle 706. The connecting plate 701 is fixed at one end of the rotating mechanism 6. The inner two side surfaces of the connecting plate 701 are provided with slide grooves 702. The inner surface of the slide groove 702 is movably connected with a clamping block 703. One side surface of the clamping block 703 is provided with an anti-slip pattern 704. A screw 705 is provided inside one side of the clamping block 703. A handle 706 is provided outside the screw 705. The second drive motor 9 drives the second screw 10 to rotate, so that the support frame 11 and the polishing disk 14 below can move and polish the surface of the display bracket, and the setting of the hydraulic cylinder 12 can adjust the polishing disk 14 according to the height of the display bracket.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, the dust suction mechanism 15 includes a dust suction head 1501, a dust suction pipe 1502, a centrifugal fan 1503, and a dust suction box 1504. The dust suction head 1501 is installed on one side of the support frame 11, one end of the dust suction head 1501 is fixedly connected to the dust suction pipe 1502, the dust suction pipe 1502 is a hose, the other end of the dust suction pipe 1502 is fixedly connected to the centrifugal fan 1503, and one side of the centrifugal fan 1503 is fixedly provided with a dust suction box 1504.

By turning on the centrifugal fan 1503 switch, the dust suction head 1501 is aimed at the debris and dust generated by the polishing disc 14 to absorb the debris and dust, which are absorbed from the dust suction pipe 1502 to the dust suction box 1504 for collection and treatment. This method improves the surrounding production environment and is also convenient for subsequent cleaning by the staff.

[0042] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and then the display bracket is placed between the two groups of movable frames 4. Next, according to the length of the display bracket, the switch of the first driving motor 2 is turned on to drive the first screw rod 3 to rotate, and the two groups of movable frames 4 outside are driven to move relative to each other through the rotation of the first screw rod 3. After moving to the appropriate length of the display bracket, the switch of the first driving motor 2 is turned off, and then the two sides of the display bracket are clamped in the connecting plate 701. According to the width of the display bracket, the two groups of clamping blocks 703 on one side of the connecting plate 701 are moved, and the clamping blocks 703 are moved to clamp the two sides of the display bracket. After the clamping is fixed, the handle 706 outside the screw rod 705 is turned, and the handle 706 is rotated to press against the top of the connecting plate 701 to limit the clamp block 703, and then the servo motor 13 switch is turned on to drive the polishing disc 14 to rotate, and then the hydraulic cylinder 12 switch is turned on to push the polishing disc 14 to move up and down, so that the polishing disc 14 contacts the surface of the display bracket and then closes the hydraulic cylinder 12 switch, and polishes after contacting the surface of the display bracket, and then turns on the second drive motor 9 switch to drive the second screw rod 10 to rotate, so that the support frame 11 and the polishing disc 14 below move left and right. The entire display bracket surface is polished. During the polishing process, the centrifugal fan 1503 switch is turned on again, so that the dust head 1501 is aimed at the polishing disc 14 to absorb the debris and dust generated, and the dust is absorbed from the dust suction pipe 1502 to the dust suction box 1504 for collection and treatment. When the surface of one side of the display bracket is polished, it is necessary to polish other surfaces. By pulling the connecting rod 601 and the handle 602, the limit block 603 outside the connecting rod 601 is separated from the limit groove 5 in the movable frame 4, and then the handle 602 is turned to drive the connecting rod 601 and the connecting column 605 at one end and the clamping machine 1504 to move the display bracket surface to the display bracket surface. The structure 7 is rotated, and the handle 602 is released after the surface to be polished is rotated. The limit block 603 is re-stuck in the limit groove 5 in the movable frame 4 through the rebound ability of the spring 604 outside the connecting rod 601, thereby completing the rotation of the display stand, and then continuing to polish according to the previous steps. Finally, when polishing is completed, turn off the centrifugal fan 1503 switch, turn off the servo motor 13 switch, and then cut off the external power supply, and then take down the display stand. The model of the centrifugal fan 1503 is: CX-75A, and the use process of the display stand polishing device is completed.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
