[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
[0020] like Figures 1 to 3 As shown, a portable bolt external anti-corrosion grease coating device includes a coating brush head 100, a driving part 200 and a grease supply box 300.
[0021] The coating brush head 100 includes a brush head cover plate 101 , a brush head base 111 and a rotating brush frame 103 .
[0022] The brush head cover 101 is sealingly buckled on the brush head base 111 , and an oil cavity 114 is provided in the middle of the brush head base 111 .
[0023] The rotating brush frame 103 includes a rotating shaft and a brush block which are integrated from top to bottom.
[0024] The top of the rotating shaft of the rotating brush holder 103 is in the shape of a square column, and the bottom is in the shape of a cylinder. The square column shape facilitates the positioning and fastening of the rotating brush holder 103, and the cylinder shape is used to support the rotating motion.
[0025] The rotating shaft of the rotating brush frame 103 rotates sealably through the brush head cover plate 101 .
[0026] A ball bearing 102 and a skeleton oil seal 104 are arranged between the brush head cover plate 101 and the rotating brush frame 103 from bottom to top. The ball bearing 102 is used to support the relative movement between the rotating brush frame 103 and the brush head cover plate 101. The skeleton oil seal 104 seals the upper part of the oil chamber 114 to prevent grease from overflowing.
[0027] The brush block seal rotates through the brush head base 111.
[0028] A thrust ball bearing 106 and a sealing rubber ring are provided between the rotating brush frame 103 and the brush head base 111. The thrust ball bearing 106 is used to support the relative rotation between the rotating brush frame 103 and the brush head base 111. The rubber sealing ring seals the lower part of the oil chamber 114 to prevent grease from overflowing.
[0029] A coating cavity is formed on the bottom surface of the brush block of the rotating brush holder 103 , and an oil inlet hole 112 is formed on the side wall of the coating cavity.
[0030] The top wall and the inner side wall of the coating chamber of the rotating brush holder 103 are both provided with a brush and a sticky cloth 105 .
[0031] Since the coating chamber of the rotating brush holder 103 is a bottomless structure, when in use, the bolt 400 to be coated can be inserted into the coating chamber, and the brush sticky cloth 105 absorbs the grease and is wrapped around the bolt 400 to be coated. The rotating brush holder 103 can be rotated to achieve coating of the bolt 400 to be coated.
[0032] The side wall of the oil chamber 114 is connected to an oil delivery connector 108 .
[0033] A gripping handle 107 is sleeved on the outer side of the oil delivery connector 108 .
[0034] The grip handle 107 has an oil delivery channel disposed therein, and the other end of the grip handle 107 is connected to an oil supply pipe 301 on the inner side.
[0035] The gripping handle 107 is provided with an oil transfer switch 109 , which is a push-type self-locking switch. By pressing the oil transfer switch 109 , the oil transfer channel in the gripping handle 107 can be opened or closed, thereby controlling the flow and stop of grease.
[0036] The driving unit 200 includes a driving motor, and the output shaft of the driving motor is connected to a self-locking chuck 201 . The interior of the self-locking chuck 201 can be locked or released by a matching chuck key.
[0037] The self-locking chuck 201 is sleeved outside the rotating shaft of the rotating brush holder 103 and the rotating shaft is locked by a suitable chuck key. After locking, the rotation of the driving motor will drive the rotating brush holder 103 to rotate, and the brush block at the bottom of the rotating brush holder 103 will rotate synchronously, and the brush adhesive cloth 105 will rotate around the bolt 400 to be coated, so as to evenly apply grease to the surface of the coating bolt 400.
[0038] The driving motor is provided with a speed regulating switch 202, which can adjust the rotation speed of the rotating brush holder 103. When different temperature environments cause the viscosity of the anti-corrosion grease to change, the rotation speed of the rotating brush holder 103 can be adjusted to achieve the best state, thereby more evenly and consistently applying grease to the bolts 400 to be coated, thereby ensuring the coating effect.
[0039] The driving part 200 includes a fixed rubber ring 203, which can fix the chuck key of the self-locking chuck 201 to prevent the chuck key from being lost. The fixed rubber ring 203 is elastic, and the chuck key can be put in or taken out by pulling the fixed rubber ring 203.
[0040] The grease supply box 300 is provided with a pressure rod 303 .
[0041] A pressing plate 305 is connected to the lower part of the pressure rod 303 , and the pressing plate 305 is sealingly and slidably connected to the side wall of the grease supply box 300 .
[0042] The top of the pressure rod 303 passes through the grease supply box 300 , and a pressure block 304 is placed on the top of the pressure rod 303 .
[0043] The bottom of the side wall of the grease supply box 300 is connected with an oil supply interface 302 , and the oil supply interface 302 is connected with the end of the oil supply pipe 301 .
[0044] Under the pressure of the pressing block 304, the pressing plate 305 will slide downward along the inner wall of the grease supply box 30. The grease supply box 300 below the pressing plate 305 is filled with grease. As the pressing plate 305 moves downward, the grease below the pressing plate 305 will be pressed out from the oil supply interface 302 into the oil supply pipe 301. The grease flows from the oil supply pipe 301 to the gripping handle 107, and then enters the oil chamber 114 through the oil delivery connector 108. The grease in the oil chamber 114 enters the coating chamber through the oil inlet hole on the rotating brush holder 103 and is absorbed by the brush cloth 105. The brush cloth 105 evenly coats the bolts 400 to be coated.
[0045] The holding handle 107 is connected with a fastening ring 113, which is sleeved on the outside of the brush head base 111. The fastening ring 113 is a metal ring, which is surrounded by metal strips. After the metal strips are formed into a metal ring and sleeved on the outside of the brush head base 111, the two sides of the metal strips are tightened with bolts to form the fastening ring 113 and fixed outside the brush head base 111.
[0046] The fastening ring 113 securely connects the gripping handle 107 and the brush head base 111 to prevent the gripping handle 107 from being removed from the oil delivery connector 108 .
[0047] An anti-drag hanging ring 110 is fixedly connected between the oil supply pipe 301 and the holding handle 107 .
[0048] The anti-drag hanging ring 110 connects the gripping handle 107 and the oil supply pipe 301 together to prevent the oil supply pipe 301 from falling out of the gripping handle 107 when the oil supply pipe 301 is dragged, thereby ensuring that the oil supply pipe 301 supplies oil to the rotating brush holder 103 smoothly.
[0049] When the present invention is in use, the pressing plate 305 moves downward under the pressure of the pressing block 304, and the squeezed grease flows from the oil supply interface 302 into the oil supply pipe 301, and then into the oil chamber 114. The grease in the oil chamber 114 flows into the oil inlet hole 112 and is absorbed by the brush cloth 105. The bolt 400 to be coated is wrapped by the brush cloth 105, and the driving motor is started for uniform coating.
[0050] When the present invention applies grease to the surface of the bolt, the grease is applied evenly without wasting grease, and the appearance is uniform. The concentration change of the anti-corrosion grease caused by temperature difference can be adjusted by changing the rotation speed, and the coating efficiency is high and the quality is good.
[0051] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
