Description

Technical Field

[0001] This utility model relates to the field of four-jaw chuck lubrication technology, specifically a dynamic self-lubricating mechanism for a four-jaw chuck. Background Technology

[0002] Four-jaw chucks are common machine tool fixtures, mainly used on lathes, grinding machines, milling machines, and other machine tools. They are used to clamp workpieces and rotate with the spindle for machining. A four-jaw chuck refers to a mechanical device with four independently moving jaws (clamping jaws). The position of each jaw can be adjusted individually through a power drive to clamp the workpiece. It is an indispensable tool in machining and is widely used in manufacturing, repair shops, and mold making. Existing four-jaw chucks have the following problems: they require machine shutdown for lubrication, affecting production efficiency; manual lubrication can easily lead to localized over- or under-lubrication; and manual lubrication poses certain safety hazards. Furthermore, the high-speed operation of the moving parts of the four-jaw chuck generates frictional heat, accelerating wear and affecting clamping accuracy and lifespan. Therefore, it is of great significance to design a dynamic self-lubricating mechanism for four-jaw chucks to achieve lubrication during operation without stopping the machine manually.

[0028] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] Example

[0030] like Figures 1-7 As shown, a four-jaw chuck dynamic self-lubricating mechanism includes: a drive base 1, a four-jaw chuck 101, a rotating shaft 102, a transmission gear 103, and a lubrication assembly. The four-jaw chuck 101 is provided at the outer end of the drive base 1, and the rotating shaft 102 is installed inside the drive base 1. The transmission gear 103 is installed on the rotating shaft 102. The top of the transmission gear 103 is provided with a lubrication assembly for lubricating the transmission gear 103 and preventing wear. The lubrication assembly includes: a fixing frame 2, an oil storage box 201, a micro oil pump 202, an oil suction pipe 203, an oil delivery pipe 204, an oil outlet head 205, and a through groove 206.

[0031] The drive base 1 has a servo motor 104 installed at its outer end, and a drive gear 105 is installed at the drive shaft end of the servo motor 104. The drive gear 105 is meshed with the transmission gear 103. An outer sleeve 106 is installed between the drive base 1 and the four-jaw chuck 101, and the rotating shaft 102 is located inside the outer sleeve 106.

[0032] When the four-jaw chuck 101 is in use, it is mounted on the lathe via the drive seat 1. The servo motor 104 is externally powered to the lathe and is electrically connected to the control box of the lathe. The servo motor 104 is started by the control box. The servo motor 104 drives the drive gear 105 to rotate the transmission gear 103, which in turn drives the rotating shaft 102 to rotate, thereby adjusting the position of each jaw to clamp the workpiece. This is common knowledge to those skilled in the art, so it will not be described in detail.

[0033] During use, the shaft 102 is protected by the outer protective sleeve 106 to prevent the shaft 102 from being exposed to the outside and getting in the way of debris, which would affect its normal operation.

[0034] The servo motor 104 is equipped with a protective housing 107 on its outer end, and the drive gear 105 is located inside the protective housing 107. The protective housing 107 is also equipped with a mounting plate. piece 108, Installation piece108 is fixedly installed to the outer end of the drive seat 1 by bolts. The outer end of the rotating shaft 102 is provided with a rotating head 109. The rotating head 109 is equipped with a bearing that is rotatably connected to the rotating shaft 102. The outer end of the rotating head 109 is installed and connected to the fixed frame 2.

[0035] When using the servo motor 104, it is connected to the protective housing 107 and the mounting... piece 108 can mount the servo motor 104 on the outer end of the drive base 1, so that the servo motor 104 and the drive gear 105 are used in conjunction with the transmission gear 103. During use, the drive gear 105 can be protected by the protective shell 107 to prevent debris from getting between the teeth and affecting normal operation.

[0036] Among them, a fixed frame 2 is installed on one side of the top of the drive seat 1, an oil storage box 201 is installed on the top of the fixed frame 2, a micro oil pump 202 is installed on the top of the oil storage box 201, an oil suction pipe 203 is installed between the micro oil pump 202 and the oil storage box 201, an oil delivery pipe 204 is installed on the outer end of the micro oil pump 202, an oil outlet head 205 is installed at the bottom of the oil delivery pipe 204, and a through groove 206 is opened at the position of the top of the fixed frame 2 relative to the transmission gear 103, and the oil outlet head 205 is located inside the through groove 206.

[0037] During operation, the drive gear 105 drives the transmission gear 103 to rotate. Due to the frequent opening and closing of the four-jaw chuck 101 to clamp the workpiece, the drive gear 105 and transmission gear 103 experience wear and heat due to prolonged friction, affecting their service life. Without stopping the machine, operators can observe the condition of the drive gear 105 and transmission gear 103 from outside the lathe. If the lubrication of the drive gear 105 and transmission gear 103 is poor, they can be lubricated. Specifically, the micro oil pump 202 is electrically connected to the lathe's control box, and like the lathe, it is powered by an external power source. The micro oil pump 202 is started by the control box, and the oil suction pipe 203 draws oil from the oil reservoir 203. The lubricating oil stored inside 01 is extracted and discharged into the micro oil pump 202. The micro oil pump 202 then discharges the lubricating oil into the oil delivery pipe 204, which delivers the lubricating oil to the oil outlet 205. Since the oil outlet 205 is located inside the through groove 206 and is directly opposite the transmission gear 103, the lubricating oil can drip from the oil outlet 205 onto the transmission gear 103. When the transmission gear 103 and the drive gear 105 mesh and rotate, the lubricating oil can be evenly distributed into the teeth of the transmission gear 103 and the drive gear 105. This effectively solves the problem of friction and heat generation during high-speed operation of the transmission gear 103 and the drive gear 105, which accelerates the wear of parts and affects the clamping accuracy and life. Moreover, there is no need to stop the machine for lubrication, which improves production efficiency and reduces the safety hazards of manual lubrication.

[0038] The small opening diameter of the oil outlet 205 effectively avoids wasting lubricating oil during the discharge process and allows observation of the lubrication status of the transmission gear 103. Once the teeth of the transmission gear 103 are lubricated, the micro oil pump 202 can be shut off via the control box. If necessary, the micro oil pump 202 can be restarted via the control box.

[0039] The oil storage box 201 has a liquid level window 207 on the outside and an oil injection pipe 208 installed on the top of the oil storage box 201. The top of the oil injection pipe 208 is threaded with a sealing cap 209.

[0040] During the use of the oil reservoir 201, the staff can observe the oil level of the oil reservoir 201 through the liquid level window 207. When the lubricating oil stored in the oil reservoir 201 is almost used up, the sealing cap 209 on the top of the oil filling pipe 208 can be loosened and opened, and lubricating oil can be added into the oil reservoir 201 through the oil filling pipe 208 for storage and backup, so as to avoid the micro oil pump 202 from being damaged by dry burning.

[0041] The transmission gear 103 and the drive gear 105 are provided with a collection box 3 at their bottom. The length, width and diameter of the collection box 3 are larger than those of the transmission gear 103 and the drive gear 105.

[0042] During the lubrication process of transmission gear 103 and drive gear 105, the lubricating oil dripping from transmission gear 103 and drive gear 105 can be collected and temporarily stored through collection box 3 to avoid it falling onto the lathe and being wasted.

[0043] The collection box 3 has a filter bucket 301 at the top inside, a filter screen at the bottom of the filter bucket 301, and limiting strips 302 for supporting the filter bucket 301 installed on both sides of the inner wall of the collection box 3.

[0044] When using the collection box 3, first place the filter bucket 301 inside the collection box 3. The filter bucket 301 is supported and placed stably by the limiting strips 302 on both sides of the inner wall of the collection box 3. When the collection box 3 collects the lubricating oil dripping from the transmission gear 103 and the drive gear 105, the impurity particles in the lubricating oil can be filtered clean through the filter bucket 301 and the filter screen, ensuring that the lubricating oil does not contain impurity particles when it is recycled and reused, and avoiding blockage and damage to the micro oil pump 202.

[0045] Working principle:

[0046] When the four-jaw chuck 101 is in use, it is mounted on the lathe via the drive seat 1. The servo motor 104 is externally powered to the lathe and is electrically connected to the control box of the lathe. The servo motor 104 is started by the control box. The servo motor 104 drives the drive gear 105 to rotate the transmission gear 103, which in turn drives the rotating shaft 102 to rotate, thereby adjusting the position of each jaw and clamping the workpiece.

[0047] During operation, the drive gear 105 drives the transmission gear 103 to rotate. Due to the frequent opening and closing of the four-jaw chuck 101 to clamp the workpiece, the drive gear 105 and transmission gear 103 experience wear and heat due to prolonged friction, affecting their service life. Without stopping the machine, operators can observe the condition of the drive gear 105 and transmission gear 103 from outside the lathe. If the lubrication of the drive gear 105 and transmission gear 103 is poor, they can be lubricated. Specifically, the micro oil pump 202 is electrically connected to the lathe's control box, and like the lathe, it is powered by an external power source. The micro oil pump 202 is started by the control box, and the oil suction pipe 203 draws oil from the oil reservoir 203. The lubricating oil stored inside 01 is extracted and discharged into the micro oil pump 202. The micro oil pump 202 then discharges the lubricating oil into the oil delivery pipe 204, which delivers the lubricating oil to the oil outlet 205. Since the oil outlet 205 is located inside the through groove 206 and is directly opposite the transmission gear 103, the lubricating oil can drip from the oil outlet 205 onto the transmission gear 103. When the transmission gear 103 and the drive gear 105 mesh and rotate, the lubricating oil can be evenly distributed into the teeth of the transmission gear 103 and the drive gear 105. This effectively solves the problem of friction and heat generation during high-speed operation of the transmission gear 103 and the drive gear 105, which accelerates the wear of parts and affects the clamping accuracy and life. Moreover, there is no need to stop the machine for lubrication, which improves production efficiency and reduces the safety hazards of manual lubrication.

[0048] During the lubrication of transmission gear 103 and drive gear 105, the lubricating oil dripping from transmission gear 103 and drive gear 105 can be collected and temporarily stored through collection box 3 to avoid it falling onto the lathe and being wasted. Furthermore, the filter bucket 301 and filter screen can filter out impurities in the lubricating oil, ensuring that the lubricating oil is free of impurities when recycled and reused, thus preventing the micro oil pump 202 from becoming clogged and damaged.
