Description
Technical Field
[0001] This invention belongs to the field of clock spring processing technology, specifically an oil injection platform for clock spring processing. Background Technology
[0002] Currently, clock springs require oil injection during processing to lubricate the internal components and ensure their efficient operation.
[0003] In existing technologies, clock springs are mostly lubricated using an oiling head. This head locks the clock spring and injects a small amount of oil into it. Once the small amount of oil enters the clock spring, it needs to rely on its own flow properties to disperse the oil to various areas inside the clock spring. This process is often time-consuming. Moreover, because the amount of oil injected into the clock spring is small, it is often difficult to evenly distribute the small amount of oil to various positions inside the clock spring, thus affecting the lubrication effect. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide an oil injection platform for clock spring processing.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An oil injection platform for machining clock springs includes an oil injection table, a piston tube, a piston assembly, a drive assembly, and a reset assembly. A support plate is fixedly installed on the upper part of the oil filling platform. The piston tube is movably disposed on one side of the support plate, and one end of the piston assembly extends into the interior of the piston tube, while the other end extends above the piston tube. The drive assembly and the reset assembly are mounted on the side wall of the support plate. The drive assembly and the reset assembly cooperate to drive the piston tube and the piston assembly to move up and down. When the piston assembly moves downward, it presses a metered amount of oil and air into the clock spring through the piston tube. When the piston assembly moves upward, it draws a metered amount of oil and air from the outside into the piston tube.
[0006] As a further improvement of the present invention: the piston assembly includes a piston block and a piston rod. The piston block is movably disposed inside the piston tube. One end of the piston rod is fixedly connected to the piston block, and the other end extends above the piston tube. Several toothed plates are fixedly disposed on the side wall of the piston rod above the piston rod, and the several toothed plates are vertically spaced. The drive assembly includes an incomplete gear, a shaft, and a motor. The motor is fixedly mounted on the side wall of the bracket plate. One end of the rotating shaft is connected to the motor, and the other end is connected to the incomplete gear. The incomplete gear is located on one side of the piston rod and can mesh with several of the gear plates.
[0007] As a further improvement of the present invention: the bottom of the piston tube is provided with a conical nozzle, the conical surface of the conical nozzle is provided with a plurality of oil injection holes, and the bottom of the conical nozzle is provided with an exhaust hole. An exhaust pipe is fixedly installed on the side wall of the piston tube. One end of the exhaust pipe extends to the outside of the piston tube, and the other end extends into the inside of the conical nozzle and communicates with the exhaust hole.
[0008] As a further improvement of the present invention: a support plate is fixedly disposed on the inner wall of the piston tube, the piston rod passes through the support plate and is movably engaged with the support plate, the support plate and the piston block are connected by a first elastic element, the first elastic element is used to provide elastic tension to the piston block, and a slider is fixedly disposed on the outer wall of the piston tube, the slider being slidably engaged with the support plate. The reset assembly includes a limiting block, a third elastic element, and a support block. The limiting block and the supporting block are fixedly installed on the side wall of the bracket plate. The limiting block is located above the slider, and the supporting block is located below the slider. One end of the third elastic element is connected to the slider, and the other end is connected to the supporting block, which is used to provide elastic support for the slider.
[0009] As a further improvement of the present invention: the reset assembly further includes a guide rail, which is vertically distributed and fixedly installed on the side wall of the bracket plate, and the slider slides in cooperation with the guide rail.
[0010] As a further improvement of the present invention: an air inlet pipe and an oil inlet pipe are also provided on the side wall of the piston tube, the end of the oil inlet pipe away from the piston tube is connected to an external oil tank, and a one-way valve is provided inside the air inlet pipe, the oil inlet pipe and the piston tube.
[0011] As a further improvement of the present invention: a baffle is fixedly provided at the bottom of the piston block, the baffle is in contact with the inner wall of the piston tube, and an opening is provided on the baffle.
[0012] As a further improvement to the present invention: the oil injection platform for clock spring processing also includes a limiting component. Before the tapered nozzle at the bottom of the piston tube extends into the oil inlet of the clock spring, the limiting assembly serves to bind the piston rod and the piston tube together as one unit. After the conical nozzle at the bottom of the piston tube extends into the oil inlet of the clock spring, the limiting assembly releases the limiting state between the piston rod and the piston tube.
[0013] As a further improvement of the present invention: a limiting ring is also fixedly provided on the inner wall of the piston tube, the piston rod passes vertically through the inside of the limiting ring, and the piston rod has a cavity inside. The limiting assembly includes a first movable block, a swing arm, a second elastic element, and a second movable block. The first movable block extends at one end between two adjacent sets of teeth and has a first inclined surface, while the other end passes through the piston rod sidewall and extends into the cavity. The second movable block acts on the upper part of the limiting ring at one end and has a second inclined surface, while the other end passes through the piston rod sidewall and extends into the cavity. The swing arm is disposed inside the cavity. The side wall of the swing arm is rotatably connected to the inner wall of the cavity via a pin. One end of the swing arm is hinged to the first movable block and the other end is hinged to the second movable block. One end of the second elastic element is connected to the inner wall of the cavity and the other end is connected to the swing arm, which is used to provide elastic tension to the swing arm.
[0014] As a further improvement of the present invention: the first elastic element, the second elastic element and the third elastic element are springs or metal sheets.
[0015] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, initially, the piston tube contains a fixed amount of oil. When the clock spring needs to be lubricated, the clock spring can be placed on the upper part of the lubrication platform, so that the lubrication port of the clock spring is located at the bottom of the piston tube. Then, the drive assembly moves the piston tube and piston assembly downwards. When the piston tube moves downwards, its bottom extends into the lubrication port of the clock spring. Subsequently, as the piston assembly continues to move downwards, the piston assembly pumps the fixed amount of oil inside the piston tube into the clock spring, realizing automatic lubrication of the clock spring. After the fixed amount of oil enters the clock spring, the piston assembly continues to move downwards to pump the fixed amount of air inside the piston tube into the clock spring. After air enters the clock spring, it blows the oil that previously entered the clock spring, causing the oil to quickly disperse to various areas inside the clock spring, thereby improving the oiling effect. After the current clock spring is oiled, the reset component moves the piston tube and piston assembly upward. When the piston assembly moves upward, it draws a fixed amount of oil and air from the outside into the piston tube, realizing the automatic replenishment of oil and air to continue oiling subsequent clock springs. Compared with the existing technology, it can not only realize the automatic oiling of clock springs, but also drive the oil injected into the clock spring to automatically disperse to various areas, thereby achieving uniform oiling of the clock spring.

[0017] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

Therefore, they should not be construed as limitations on this invention.
[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0021] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This embodiment provides an oil injection platform for clock spring processing, including an oil injection platform 10, a piston tube 20, a piston assembly 30, a drive assembly 40, and a reset assembly 60. A support plate 101 is fixedly installed on the upper part of the oil injection platform 10. The piston tube 20 is movably installed on one side of the support plate 101. One end of the piston assembly 30 extends into the piston tube 20, and the other end extends above the piston tube 20. The drive assembly 40 and the reset assembly 60 are installed on the side wall of the support plate 101. The drive assembly 40 and the reset assembly 60 cooperate to drive the piston tube 20 and the piston assembly 30 to move up and down. When the piston assembly 30 moves down, it presses a metered amount of oil and a metered amount of air into the clock spring through the piston tube 20. When the piston assembly 30 moves up, it draws a metered amount of oil and a metered amount of air from the outside into the piston tube 20.
[0022] Initially, the piston tube 20 contains a fixed amount of oil. When the clock spring needs to be lubricated, the clock spring can be placed on the upper part of the lubrication platform 10, so that the lubrication port of the clock spring is located at the bottom of the piston tube 20. Then, the drive assembly 40 drives the piston tube 20 and the piston assembly 30 to move downward. When the piston tube 20 moves downward, its bottom extends into the lubrication port of the clock spring. Subsequently, as the piston assembly 30 continues to move downward, the piston assembly 30 pumps the fixed amount of oil inside the piston tube 20 into the clock spring, realizing the automatic lubrication of the clock spring. After the fixed amount of oil enters the clock spring... The piston assembly 30 continues to move downward to pressurize the metered air inside the piston tube 20 into the clock spring. When the air enters the clock spring, it can blow the oil that previously entered the clock spring, causing the oil to quickly disperse to various areas inside the clock spring, thereby improving the oiling effect. After the current clock spring is oiled, the reset assembly 60 drives the piston tube 20 and the piston assembly 30 to move upward. When the piston assembly 30 moves upward, it draws the metered oil and metered air from the outside into the piston tube 20, realizing the automatic replenishment of oil and air to continue oiling the subsequent clock springs.
[0023] Please see Figure 1 , Figure 3 as well as Figure 5 In one embodiment, the piston assembly 30 includes a piston block 301 and a piston rod 303. The piston block 301 is movably disposed inside the piston tube 20. One end of the piston rod 303 is fixedly connected to the piston block 301, and the other end extends above the piston tube 20. A plurality of toothed plates 304 are fixedly disposed on the rod side wall above the piston rod 20. The plurality of toothed plates 304 are vertically spaced apart. The drive assembly 40 includes an incomplete gear 401, a rotating shaft 402, and a motor 403. The motor 403 is fixedly mounted on the side wall of the support plate 101. One end of the rotating shaft 402 is connected to the motor 403, and the other end is connected to the incomplete gear 401. The incomplete gear 401 is located on one side of the piston rod 303 and can mesh with the plurality of toothed plates 304.
[0024] After the clock spring is placed on the upper part of the oil filling platform 10 and the oil filling port of the clock spring is located below the piston tube 20, the motor 403 drives the rotating shaft 402 to rotate, which in turn drives the incomplete gear 401 to rotate. When the incomplete gear 401 rotates, it meshes with several gears 304, which in turn drives the piston rod 303 to move down. When the piston rod 303 moves down, it drives the piston block 301 and the piston tube 20 to move down. When the bottom of the piston tube 20 extends into the oil filling port of the clock spring, the piston tube 20 stops moving down. The piston rod 303 drives the piston block 301 to continue moving down. The piston block 301 pre-pumps a metered amount of oil located at the bottom of the inner side of the piston tube 20 into the clock spring. After the metered amount of oil enters the clock spring, the piston block 301 then pumps a metered amount of air into the clock spring, which blows the metered amount of oil that previously entered the clock spring into various positions inside the clock spring, so that the metered amount of oil is evenly distributed inside the clock spring to improve the oil filling effect.
[0025] Please see Figure 1 , Figure 4 as well as Figure 8 In one embodiment, the piston tube 20 is provided with a conical nozzle at the bottom, and a plurality of oil injection holes 201 are provided on the conical surface of the conical nozzle. An exhaust hole 2087 is provided at the bottom of the conical nozzle. An exhaust pipe 204 is fixedly provided on the side wall of the piston tube 20. One end of the exhaust pipe 204 extends to the outside of the piston tube 20, and the other end extends to the inside of the conical nozzle and communicates with the exhaust hole 2087.
[0026] As the piston tube 20 moves downward, its conical nozzle at the bottom extends into the oil inlet of the clock spring. As the piston block 301 continues to move downward along the inside of the piston tube 20, the piston block 301 applies pressure to the metered oil in the conical nozzle, causing the metered oil to enter the clock spring through several oil inlets 201. After the metered oil enters the clock spring, the piston block 301 then pushes the metered air inside the piston tube 20 into the clock spring through the oil inlets 201, causing the metered oil that previously entered the clock spring to spread evenly. Since the inside of the clock spring is relatively sealed, when the metered air enters the clock spring, it can drive the original air inside the clock spring to be discharged from the exhaust port 208 to the exhaust pipe 204, and then discharged to the outside through the exhaust pipe 204.
[0027] Please see Figure 1 as well as Figure 2In one embodiment, a support plate 205 is fixedly disposed on the inner wall of the piston tube 20, and the piston rod 303 passes through the support plate 205 and is movably engaged with the support plate 205. The support plate 205 and the piston block 301 are connected by a first elastic element 302, which provides elastic tension to the piston block 301. A slider 206 is fixedly disposed on the outer wall of the piston tube 20, and the slider 206 is slidably engaged with the bracket plate 101. The reset assembly 60 includes a limiting block 601, a third elastic element 603, and a support block 604. The limiting block 601 and the support block 604 are fixedly installed on the side wall of the bracket plate 101. The limiting block 601 is located above the slider 206, and the support block 604 is located below the slider 206. One end of the third elastic element 603 is connected to the slider 206, and the other end is connected to the support block 604, which provides elastic support to the slider 206.
[0028] When the incomplete gear 401 meshes with several gear pieces 304, thereby driving the piston rod 303 to move downward, the piston rod 303 drives the piston block 301 and the piston cylinder 20 to move downward. When the piston cylinder 20 moves downward, it drives the slider 206 to slide down along the side wall of the support plate 101. The third elastic element 603 is compressed by force. When the conical nozzle at the bottom of the piston tube 20 is inserted into the oil inlet of the clock spring, the piston tube 20 stops moving downward, while the piston rod 303 and the piston block 301 continue to move downward to pressurize a metered amount of oil and a metered amount of air into the clock spring. When the piston block 301 moves downward along the inside of the piston tube 20, the first elastic element 302 is compressed. Force stretching; when a fixed amount of air enters the clock spring to blow away a fixed amount of oil, the incomplete gear 401 disengages from several toothed plates 304, the third elastic element 603 pushes the slider 206 so that the slider 206 slides up along the side wall of the support plate 101, thereby driving the piston tube 20 to move upward. At the same time, the first elastic element 302 pulls the piston block 301 so that the piston block 301 moves upward relative to the piston tube 20, thereby driving the piston rod 303 to move upward, thereby realizing the reset of the piston tube 20, the piston block 301 and the piston rod 303. When the piston tube 20 is reset, the slider 206 acts on the bottom of the limit block 601.
[0029] Please see Figure 2 In one embodiment, the reset assembly 60 further includes a guide rail 602, which is vertically distributed and fixedly installed on the side wall of the bracket plate 101, and the slider 206 slides in cooperation with the guide rail 602.
[0030] Please see Figure 1 as well as Figure 2In one embodiment, an air inlet pipe 202 and an oil inlet pipe 203 are also provided on the side wall of the piston tube 20. The end of the oil inlet pipe 203 away from the piston tube 20 is connected to an external oil tank (not shown in the figure). A one-way valve (not shown in the figure) is provided inside the air inlet pipe 202, the oil inlet pipe 203 and the piston tube 20.
[0031] When the piston block 301 moves downward relative to the inside of the piston tube 20, the one-way valves inside the air inlet pipe 202 and the oil inlet pipe 203 close, while the one-way valve inside the piston tube 20 opens. The piston block 301 pre-pressurizes the metered oil inside the conical nozzle, causing the metered oil and metered air to enter the clock spring successively through several oil injection holes 201. When the piston block 301 moves upward relative to the inside of the piston tube 20, the one-way valves inside the air inlet pipe 202 and the oil inlet pipe 203 open, while the one-way valve inside the piston tube 20 closes. This allows the metered air from the outside to be drawn into the piston tube 20 through the air inlet pipe 202, and the metered oil from the external oil tank to be drawn into the piston tube 20 through the oil inlet pipe 203, thus achieving automatic replenishment of the metered oil and metered air.
[0032] When piston block 301 moves upward relative to piston tube 20, oil and air are simultaneously drawn into piston tube 20 from oil inlet pipe 203 and air inlet pipe 202 respectively under negative pressure. At this time, the negative pressure on air inlet pipe 202 and oil inlet pipe 203 is prone to uneven distribution, resulting in too much or too little air entering piston tube 202 from air inlet pipe 202 and too much or too little oil entering piston tube 203 from oil inlet pipe 203. This makes it impossible to achieve quantitative extraction of oil and air. To avoid this phenomenon, please refer to... Figure 7 In one embodiment, a baffle 305 is fixedly provided at the bottom of the piston block 301. The baffle 305 is in contact with the inner wall of the piston tube 20, and an opening 306 is provided on the baffle 305.
[0033] As the piston block 301 moves upward along the inside of the piston tube 20, it causes the baffle 305 to move upward against the inner wall of the piston tube 20. The port 306 is pre-acting on the inside of the oil inlet pipe 203 and is in a state of communication with the oil inlet pipe 203. The baffle 305 is in a state of blocking the air inlet pipe 202. At this time, the negative pressure generated when the piston block 301 moves upward acts on the oil inlet pipe 203, thereby drawing oil from the external oil tank into the piston tube 202 through the oil inlet pipe 203 and the port 306. Inside the piston tube 20, when the amount of oil entering the piston tube 20 reaches a predetermined value, the port 306 is misaligned with the oil inlet pipe 203 and connects with the air inlet pipe 202. The baffle 305 blocks the oil inlet pipe 203. At this time, the negative pressure generated when the piston block 301 moves upward acts on the air inlet pipe 202, and then draws in outside air through the air inlet pipe 202 and the port 306 until the piston block 301 moves upward to the initial position, and a certain amount of air is drawn into the piston tube 20.
[0034] When the incomplete gear 401 meshes with several gear pieces 304, thereby driving the piston rod 303, piston block 301, and piston tube 20 downwards, the piston tube 20 is supported by the third elastic element 603. Therefore, the piston tube 20 and piston block 301 do not move downwards synchronously. The piston block 301 tends to move downwards relative to the inside of the piston tube 20. This causes a certain amount of oil in the conical nozzle at the bottom of the piston block 20 to be prematurely expelled before it is inserted into the oil inlet of the clock spring. Consequently, the oil cannot smoothly enter the clock spring. Based on this, please refer to... Figure 1 In one embodiment, the oil injection platform for clock spring processing further includes a limiting component 50. Before the conical nozzle at the bottom of the piston tube 20 extends into the oil injection port of the clock spring, the limiting component 50 is used to limit the piston rod 303 and the piston tube 20 as one unit, so that the piston rod 303, piston block 301 and piston tube 20 can move down synchronously to avoid premature pressure leakage of the metered oil. After the conical nozzle at the bottom of the piston tube 20 extends into the oil injection port of the clock spring, the limiting component 50 releases the limiting state between the piston rod 303 and the piston tube 20, so that the piston rod 303 and piston block 301 can continue to move down to smoothly pressurize the metered oil and metered air into the clock spring.
[0035] Please see Figure 5 as well as Figure 6In one embodiment, a limiting ring 207 is fixedly provided on the inner wall of the piston tube 20. The piston rod 303 passes vertically through the limiting ring 207. The piston rod 303 has a cavity inside. The limiting assembly 50 includes a first movable block 501, a rocker arm 502, a second elastic element 503, and a second movable block 505. One end of the first movable block 501 extends between two adjacent sets of teeth 304 and has a first inclined surface. The other end passes through the side wall of the piston rod 303 and extends into the cavity. The second movable block 505... One end acts on the upper part of the limiting ring 207 and is provided with a second inclined surface, and the other end passes through the side wall of the piston rod 303 and extends into the cavity. The swing rod 502 is disposed inside the cavity. The side wall of the swing rod 502 is rotatably connected to the inner wall of the cavity through a pin 504. One end of the swing rod 502 is hinged to the first movable block 501, and the other end is hinged to the second movable block 505. One end of the second elastic element 503 is connected to the inner wall of the cavity, and the other end is connected to the swing rod 502, which is used to provide elastic tension to the swing rod 502.
[0036] Initially, one end of the second movable block 505 acts on the upper part of the limiting ring 207. When the incomplete gear 401 meshes with several gear pieces 304 to drive the piston rod 303 and piston block 301 to move downward, the piston rod 303 provides downward pressure on the limiting ring 207 through the pin 505, the rocker arm 502, and the second movable block 505, causing the piston tube 20 to move downward synchronously with the piston rod 303. At this time, the piston block 301 and the piston tube 20 are relatively stationary, and the piston block 301 cannot apply pressure to the metered oil in the conical nozzle, thereby preventing the metered oil from being prematurely forced out from the oil filling hole 201. The conical nozzle at the bottom of the piston tube 20 extends into the oil filling port of the clock spring. Afterwards, a set of teeth of the incomplete gear 401 acts on the first inclined surface at one end of the first movable block 501, thereby pushing the first movable block 501 to move into the cavity. When the first movable block 501 moves, it drives the rocker arm 502 to rotate relative to the pin 504. When the rocker arm 502 rotates, the second elastic element 503 is stretched. At the same time, the rocker arm 502 drives the second movable block 505 to move into the cavity, causing one end of the rocker arm 502 to disengage from the upper part of the limiting ring 207, thereby releasing the limiting state between the piston rod 303 and the piston tube 20. Subsequently, as the incomplete gear 401 continues to mesh with several subsequent gear pieces 304, the piston rod 30... 3. As the piston block 301 continues to move downward, it sequentially presses a metered amount of oil and a metered amount of air into the clock spring. When the piston rod 303 continues to move downward, the second movable block 505 passes through the inner side of the limiting ring 207 and moves below the limiting ring 207. After the clock spring is fully oiled, the incomplete gear 401 disengages from several gear pieces 304. The third elastic element 603 pushes the slider 203, causing the piston tube 20 to move upward. The first elastic element 302 pulls the piston block 301, causing the piston block 301 and piston rod 303 to move upward relative to the piston tube 20, thereby drawing a metered amount of external oil and a metered amount of external air into the piston tube 20. The piston rod 303... When the second movable block 505 moves upward, the second inclined surface at one end of the second movable block 505 acts on the inner edge of the bottom of the limiting ring 207, and then moves into the cavity again. When the second movable block 505 moves into the cavity again, it causes the rocker arm 502 to rotate again relative to the pin 505. The second elastic element 503 is pulled again until the second movable block 505 passes through the inside of the limiting ring 207 in the opposite direction and moves to the top of the limiting ring 207. Then the second elastic element 503 pulls the rocker arm 502 to rotate in the opposite direction, and the second movable block 505 moves out of the cavity, thereby acting on the upper part of the limiting ring 207 again to fix the piston rod 303 and the piston tube 20 into one unit again.
[0037] In one embodiment, the first elastic element 302, the second elastic element 503, and the third elastic element 603 can be springs or metal sheets, and there is no limitation here.
[0038] In this embodiment of the invention, initially, the piston tube 20 contains a fixed amount of oil. When it is necessary to lubricate the clock spring, the clock spring can be placed on the upper part of the lubrication platform 10, so that the lubrication port of the clock spring is located at the bottom of the piston tube 20. Then, the drive assembly 40 drives the piston tube 20 and the piston assembly 30 to move downward. When the piston tube 20 moves downward, its bottom extends into the lubrication port of the clock spring. Subsequently, as the piston assembly 30 continues to move downward, the piston assembly 30 pumps the fixed amount of oil inside the piston tube 20 into the clock spring, realizing automatic lubrication of the clock spring. After the fixed amount of oil enters the clock spring, the piston assembly 30 continues to move downward to pump the fixed amount of air inside the piston tube 20 into the clock spring. Inside the clock spring, when air enters, it blows the oil that previously entered the clock spring, causing the oil to quickly disperse to various areas inside the clock spring, thereby improving the oiling effect. After the current clock spring is oiled, the reset component 60 drives the piston tube 20 and piston assembly 30 to move upward. When the piston assembly 30 moves upward, it draws a fixed amount of external oil and a fixed amount of external air into the piston tube 20, realizing the automatic replenishment of oil and air to continue oiling subsequent clock springs. Compared with the existing technology, it can not only realize the automatic oiling of clock springs, but also drive the oil injected into the clock spring to automatically disperse to various areas, thereby achieving uniform oiling of the clock spring.
[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
