[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figures 1 to 5 As shown, a welding rod grinding device of the utility model includes a grinder 10, a grinding head 12 for grinding is provided on the rotating shaft of the grinder 10, a baffle 14 is provided on the side of the grinder 10 facing its rotating shaft, a through groove is provided on the baffle 14 for the rotating shaft of the grinder 10 to pass through, a baffle 16 is provided on one side of the baffle 14, and extensions 18 are provided on both sides of the baffle 16, and a baffle bar 22 parallel to the baffle 16 is provided on the baffle 14, and a side of the baffle bar 22 facing away from the baffle 16 corresponds to a side of the grinding head 12 away from the baffle 16 in the diameter direction.

[0021] The grinding head 12 is used for grinding welding rods. During the grinding process, the baffle 16 and the extension part 18 are wrapped around the top and both sides of the grinding head 12, which will block the waste chips during the grinding process to prevent the waste chips from splashing and injuring people. During grinding, the baffle 22 fits with the object to be polished, and the baffle 22 is flush with the grinding head 12. The baffle 22 can limit the grinding head 12, so that the grinding head 12 can prevent the object from being damaged by the grinding head 12 when grinding the welding rod.

[0022] A slide plate 24 is provided on one side of the baffle 22 facing the baffle plate 14 . A slide groove for the slide plate 24 to slide is provided on the baffle plate 14 . A strip groove 26 is provided on the slide plate 24 . A screw hole 28 corresponding to the strip groove 26 is provided on the baffle plate 14 .

[0023] For grinding heads 12 of different diameters, the bottom surface of the retaining bar 22 can be flush with the grinding head 12 by sliding the slide plate 24, and the screws are passed through the strip grooves 26 and threadedly connected to the screw holes 28 to fix the slide plate 24 and the retaining bar 22.

[0024] An arc cover 20 is provided on the side of the baffle 16 and the extension 18 away from the baffle 14. The baffle 16 is provided with an opening running through the thickness direction thereof, a hose is connected to the opening, and the other end of the hose is connected to a negative pressure machine.

[0025] During the grinding process, the negative pressure machine can collect the waste chips generated during the grinding process.

[0026] The grinding machine 10 further includes a workbench 32 , on which a slide rail 34 is disposed, on which a slider 36 is slidably disposed, and on the side wall of the grinding machine 10 , a bottom plate 30 is disposed, and the bottom plate 30 is connected to the slider 36 .

[0027] The bottom plate 30 is connected to the slider 36 , and the slider 36 slides to drive the grinder 10 to move for grinding. A person does not need to hold the grinder 10 all the time, which reduces the work intensity.

[0028] Bearing seats 42 with bearings are provided at both ends of the slide rail 34 in the length direction, a screw rod 40 is provided between the two bearing seats 42, and a motor 38 for driving the screw rod 40 to rotate is also provided at one end of the slide rail 34 in the length direction. A threaded groove threadedly connected to the screw rod 40 is opened on the slider 36.

[0029] The rotation of the motor 38 drives the screw rod 40 to rotate, and the slider 36 is restricted by the slide rail 34 and cannot rotate. When the screw rod 40 rotates, the slider 36 slides along the length direction of the screw rod 40, thereby driving the grinder 10 to move for grinding.

[0030] The workbench 32 includes a base and a panel. A gas pressure rod is arranged in the base. The top of the gas pressure rod is connected to the panel. The slide rail 34 is arranged on the panel.

[0031] The height of the workbench 32 is controlled by raising and lowering the gas pressure rod control panel.

[0032] The bottom of the workbench 32 is provided with rollers, and locking members are provided on the rollers.

[0033] The rollers facilitate the movement of the workbench 32, and the locking member is used for fixing.

[0034] Working principle: When in use, for a small number of objects to be polished, the hand-held grinder 10 can be used, and the baffle 14 and the baffle bar 22 on the grinder 10 are respectively fitted on the adjacent two sides of the object, and the grinding head 12 is located at the welding rod. The grinder 10 and the negative pressure machine are started, and the hand-held grinder 10 is moved. The baffle bar 22 limits the grinder 10 so that the grinding head 12 will not rub against the rest of the object and cause damage to the object. The baffle plate 16, the extension part 18 and the arc cover 20 prevent waste chips from splashing during grinding, and the negative pressure machine can collect the waste chips;

[0035] The baffle 16, extension 18 and arc cover 20 are all detachably connected. For different objects, there may be other structures at the welding rod, and the baffle 16, extension 18 and arc cover 20 may become obstacles. They can be disassembled by snapping together, etc., which is suitable for a variety of situations.

[0036] For a large number of objects to be polished, the base plate 30 on the polishing machine 10 can be fixed on the slider 36, and the motor 38 can be used to drive the screw rod 40 to rotate. Since the slider 36 is restricted by the slide rail 34 and cannot rotate, when the motor 38 rotates, the slider 36 will move in the length direction of the screw rod 40. The height of the workbench 32 can be adjusted by adjusting the pneumatic rod, which can be adjusted according to different objects to be polished.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
