Description

Technical Field

[0001] This utility model relates to the field of electrode cap grinding technology, and in particular to a mobile electrode cap grinding machine. Background Technology

[0002] Currently, there are still a large number of manual welding guns in the industry. When the electrode caps of manual welding guns need to be re-grinded, the electrode caps need to be removed and taken to a centralized re-grinding machine for mold repair. After the re-grinding is completed, they are reinstalled. This re-grinding method will greatly affect the production cycle. Another method is to use a pneumatic handheld re-grinding machine to re-grind the upper and lower electrode caps one by one. This re-grinding method is relatively slow and the re-grinding pressure is low, requiring multiple re-grinding operations. At the same time, the handheld re-grinding machine requires a very long air tube to complete the supply of compressed gas. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mobile electrode cap grinding machine that does not require disassembling the electrode cap or adding extra air pipes, and can complete the grinding in a single operation. Furthermore, the grinding machine can be pushed to the welding torch for direct grinding.

[0004] This utility model is achieved through the following technical solution:

[0005] A mobile electrode cap grinding machine, comprising:

[0006] The base plate is equipped with casters and fixed wheels at its bottom;

[0017] A rotating plate is rotatably connected to the rotating shaft and located outside the fixed plate, and four limiting holes are provided through the rotating plate;

[0018] The fixed plate has two plunger holes at the same height, into which a plunger can be inserted. The end of the plunger extends into the limiting hole to limit the rotation plate.

[0019] A further provision of this technical solution is that positioning plates are vertically fixed at both the upper and lower ends of the rotating plate, and the floating mechanism includes:

[0020] Guide shafts: Two guide shafts are fixed between the two positioning plates;

[0021] Springs, two springs are fitted on the outside of each guide shaft;

[0022] The intermediate flange bearing is fitted on the outside of each guide shaft, and two springs are located on both sides of the intermediate flange bearing. One end of the floating plate is fitted on the outside of the intermediate flange bearing and connected to the intermediate flange bearing.

[0027] This utility model discloses a mobile electrode cap grinding machine. Compared with the prior art, the beneficial effects of this technical solution are as follows:

[0028] 1. This technical solution involves mounting the grinding machine on a column, which is fixed to a base plate. The bottom of the base plate is equipped with casters and fixed wheels, which can push the grinding machine to the position of the welding torch to grind the electrode cap on the welding torch. At the same time, this technical solution uses a rechargeable battery to power the grinding machine, which can be freed from the constraints of the power cord and is very convenient.

[0029] 2. This technical solution uses a floating mechanism to allow the floating plate to move up and down slightly along the guide shaft during grinding, which facilitates the grinding of the electrode cap on the welding torch. The spring also absorbs the small vibrations generated.

[0030] 3. This technical solution allows the grinding machine to rotate by setting a rotating frame, thereby completing the conversion from longitudinal to transverse orientation;

[0031] 4. This technical solution facilitates the collection of waste chips from grinding by setting up a chip collection rack; and protects the battery by setting up a protective cover. Attached Figure Description

[0043] See Figures 1 to 7 As shown, a mobile electrode cap grinding machine includes: a base plate 10, on the bottom of which are mounted two casters 101 and two fixed wheels 102; a column 20, vertically fixed to the upper end of the base plate 10; a rotating frame 30, fixed to the upper part of the column 20; a floating mechanism 40 connected to the rotating frame 30, the floating mechanism 40 including a floating plate 401 that can move up and down; and a grinding machine 50, fixed to the lower end of the floating plate 401. In this technical solution, the presence of the casters 101 and fixed wheels 102 allows the grinding machine to be moved, thus moving it to the position of the welding torch for easy grinding of the electrode cap; the rotating frame 30 can control the floating mechanism 40 to rotate, i.e., control the grinding machine 50 to rotate, thereby completing the conversion from longitudinal to transverse orientation.

[0044] See Figure 1 As shown, a rechargeable battery 80 is placed on the upper end of the base plate 10. The rechargeable battery 80 is used to provide power to the grinding machine 50. A protective cover 90 is provided on the outside of the rechargeable battery 80. An electrical cabinet is also fixed on the outside of the column 20. The rechargeable battery 80 is a lithium iron phosphate battery. The rechargeable battery 80 is connected to the electrical cabinet through a wire. The electrical cabinet is connected to the grinding machine 50 through a wire. Since water may fall in during the grinding process, the protective cover 90 can prevent water from entering the battery and protect the battery.

[0045] See Figure 1As shown, at least two handles 70 are fixed to the top of the column 20; in the above technical solution, the handles 70 are designed to facilitate manual operation, and the person can hold the handles 70 to push the entire device.

[0046] See Figure 1 As shown, a mounting bracket is fixed in the middle of the column 20, and a chip collection rack 60 is fixed on the outside of the mounting bracket. The chip collection rack 60 is located below the grinding machine 50. Since the grinding machine 50 generates waste chips when grinding the electrode cap, the chip collection rack 60 is set up to facilitate the collection of waste chips, so as to make the workshop working environment cleaner.

[0047] See Figure 2 and Figure 3 As shown, the rotating frame 30 includes: a fixed plate 301, which is fixed to the outside of the column 20; a rotating shaft 302, which is fixed to the fixed plate 301 on the side away from the column 20; a rotating plate 303, which is rotatably connected to the rotating shaft 302 and located outside the fixed plate 301, and has four limiting holes 304; and plunger holes 305, with two plunger holes 305 at the same height passing through the fixed plate 301, into which plungers 306 can be inserted, and the ends of the plungers 306 extend into the limiting holes 304 to limit the rotation plate 303. In the above technical solution, the rotating shaft 302 includes a rotating end and a limiting end. The rotating end is cylindrical, and the limiting end is plate-shaped. The diameter of the limiting end is larger than the diameter of the rotating end. A first circular groove is formed in the middle of the rotating plate 303, and the middle part of the first groove is... A first through hole is provided, the diameter of the first circular groove is the same as the diameter of the limiting end, and the diameter of the first through hole is the same as the diameter of the rotating end. The mounting method of the fixed plate 301, the rotating shaft 302 and the rotating plate 303 is as follows: the rotating end of the rotating shaft 302 passes through the first through hole, so that the limiting end is located in the first circular groove, and then the rotating end of the rotating shaft 302 is fixedly connected to the fixed plate 301, so that the rotating plate 303 can rotate relative to the rotating shaft 302. The limiting hole 304 provided at the rotating plate 303 is used to cooperate with the plunger 306. The four limiting holes 304 are arranged in a square, and the diameter of the limiting hole 304 is the same as the diameter of the plunger hole 305. When the rotating plate 303 is stationary, the plunger 306 passes through the plunger hole 305 and extends into the two limiting holes 304 above. When rotation is required, it is only necessary to remove the plunger 306, rotate the rotating plate 303 by 90 degrees, and then insert the plunger 306 to fix the rotating plate 303.

[0048] See Figure 2As shown, both the upper and lower ends of the rotating plate 303 are vertically fixed with positioning plates 307. The floating mechanism 40 includes: guide shafts 402, with two guide shafts 402 fixed between the two positioning plates 307; springs 403, with two springs 403 sleeved on the outside of each guide shaft 402. The upper spring 403 contacts the upper positioning plate 307 and the intermediate flange bearing 404, and the lower spring 403 contacts the lower positioning plate 307 and the intermediate flange bearing 404. The springs 403 are in a compressed state. The intermediate flange bearing 404, each guide shaft 402... An intermediate flange bearing 404 is fitted around the outside of the shaft 402, and two springs 403 are located on both sides of the intermediate flange bearing 404 respectively. One end of the floating plate 401 is fitted around the outside of the intermediate flange bearing 404 and connected to the intermediate flange bearing 404. Two guide holes are opened at one end of the floating plate 401. The intermediate flange bearing 404 is a circular intermediate flange bearing. The flange of the intermediate flange bearing 404 is a rectangular structure. The diameter of the guide holes is the same as the outer diameter of the intermediate flange bearing 404. The floating plate 401 is fixed to the flange of the intermediate flange bearing 404.

[0049] Preferably, the spring 403 is also covered with a rubber dust cover; since it is located in a workshop environment and there may be waste chips when it is being ground, the rubber dust cover can prevent waste chips, water, dust and other substances from affecting the spring 403.

Furthermore, its output shaft is connected to the driving wheel 507. The diameter of the driven wheel 502 is larger than the diameter of the intermediate wheel 508, and the diameter of the intermediate wheel 508 is larger than the diameter of the driving wheel 507. The driving wheel 507, intermediate wheel 508, and driven wheel 502 are all gears. In the above technical solution, the specific structure of the grinding machine can be referred to the "A Grinding and Shaping Machine for Electrode Caps" disclosed in patent document "2202221026112.0". The difference between the grinding machine in this technical solution and that patent document is the size of the intermediate wheel.
