Description

Technical Field

[0001] The utility model relates to the technical field of burr devices, in particular to a protection mechanism for burr devices. Background Art

[0002] Metal stamping parts refer to the use of molds for steel or non-ferrous metal plates at room temperature, which are formed into specified shapes by a press to provide the pressure required for processing. They include some electronic devices, auto parts, decorative materials, etc. The stamping parts we usually refer to are generally cold stamped parts. Metal stamping parts generally have burrs after production, which need to be processed by burr processing equipment. The burr processing equipment can transmit fine grinding stainless steel needles to produce high-speed jumping flow, which rubs on the inner hole, dead corner, and gap surface of the workpiece to achieve polishing and burr removal effects in one go. The burr removal equipment in the prior art does not have a dustproof function.

[0003] After searching, a burr removal machine (publication number CN208288772UU) is now disclosed. This burr removal machine causes the burrs to be plastically deformed and fall off the workpiece through rolling friction with a ball and vibrating friction with a deburring needle, instead of using a wire brush or an abrasive belt brush to grind the burrs into powder. Therefore, the deburring method of the utility model hardly generates dust, thereby protecting the working environment. The ball deburring method can also effectively protect the surface of the sheet metal workpiece from damage, greatly improving the surface processing quality of the product.

[0004] However, although the above technical solution can play a good role in improving the surface processing quality of the product, the burr processing equipment is in use, and the display screen is exposed to the outside for a long time when not in use, and the environment in which it is placed is prone to dust accumulation on the outside of the display screen. The device is not provided with a relevant dust-proof structure, which leads to dust accumulation on the surface of the display screen when not in use. For this reason, we provide a protection mechanism for a burr device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a protective mechanism for a burr device, which solves the problem that dust is easily accumulated on the surface of the display screen when not in use because the device is not provided with a relevant dustproof structure.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a protective mechanism for a burr device, a dust cover, a limiting plate is arranged in the middle of one end of the dust cover, a limiting hole is opened in the middle of one end of the limiting plate, a display screen is arranged at the end of the limiting hole away from the limiting plate, one end of the display screen is connected to a limiting rod, and the other end of the display screen is connected to a storage box, a movable rod is arranged inside one end of the storage box, and a spring is connected to the outside of one end of the movable rod.

[0007] Preferably, a rotating drum is movably connected to the middle part of one end of the dust cover, and a movable rod is penetrated and connected to the interior of one end of the rotating drum.

[0008] Preferably, a transmission box is provided in the middle of one end of the display screen, and four bottom corners of the transmission box are connected to support legs.

[0009] Preferably, a second fixed machine base is provided in the middle of the lower end of the transmission box, and a second motor is connected through one end of the second fixed machine base.

[0010] Preferably, the output end of the second motor is movably connected to a turntable, and a plurality of sleeve rods are distributed at equal distances from top to bottom in the middle of the top end of the turntable.

[0011] Preferably, a first fixed machine base is provided at a middle portion of a lower end of the second fixed machine base away from the transmission box, and a first motor is connected through one end of the first fixed machine base.

[0012] Preferably, the output end of the first motor is movably connected to a first rotating rod.

[0013] Preferably, one end of the first rotating rod is movably connected to a driving wheel, and one end of the driving wheel is externally meshedly connected to a transmission belt.

[0014] Preferably, the inner side surface of one end of the transmission belt is movably connected to a driven wheel, and the outer side of one end of the driven wheel away from the first rotating rod is movably connected to the second rotating rod.

[0015] Preferably, the top end of the second rotating rod is movably connected to a thorn-removing roller.

[0016] The working principle and beneficial effects of the utility model are:

[0017] The utility model works by pulling the limit plate toward one end of the display screen when the display screen is not in use, thereby driving the dust cover to move toward the one end of the display screen, and the dust cover gradually unfolds toward the one end of the display screen under the rotation of the movable rod. When one end of the dust cover moves to the end of the display screen and completely covers the display screen, the limit plate is clamped on the limit rod through the limit hole to fix the dust cover. When the display screen needs to be opened during operation, the limit hole is removed from the limit rod, and the limit plate and the dust cover are retracted toward the inside of the storage box under the action of the spring. When the dust cover is retracted toward the inside of one end of the storage box, the display screen is gradually exposed, thereby playing a dustproof role. BRIEF DESCRIPTION OF THE DRAWINGS
