Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a roughing device for convenient clamping gear processing. Background Technology

[0002] A roughing machine is a piece of equipment used in the roughing process of gear manufacturing. Its main function is to remove excess material from the gear blank in the initial machining stage of the gear and to provide a basis for subsequent finishing.

[0003] Existing roughing machines are equipped with specialized clamps for holding gears, facilitating the rapid cutting of gear blanks. Therefore, the roughing machine itself is convenient for clamping and securing gears. During roughing, the gear is placed in the clamp and fixed in place. The roughing tool is then mounted on the machine's robotic arm. The drive motor on the robotic arm is activated to rotate the tool. Simultaneously, the robotic arm adjusts the tool's height and angle according to processing requirements, thus roughing the gear surface. During the machining process, the roughing machine is started... The drive motor on the machine rotates the fixture and the fixed gear, facilitating the machining of various parts of the gear surface. During machining, to ensure that the machining area does not overheat and cause deformation and damage to the gear surface, the water pump at the bottom of the roughing machine is usually activated to draw water from inside into the cooling nozzle and spray it to cool the machining area. The cooled water will fall freely, carrying the debris generated during the machining process into the inner wall of the roughing machine. This can cause debris mixed in with the water to be drawn into the water pump and cause blockage when the cooled water is recycled, affecting the operation of the cooling system and reducing the efficiency and quality of roughing. Utility Model Content

[0004] The technical problem this invention aims to solve is as follows: When performing rough machining on gears, the drive motor on the robotic arm can be activated to rotate the cutting tool. Simultaneously, the robotic arm can be activated to adjust the height and angle of the cutting tool according to machining requirements, thereby performing rough machining on the gear surface. During machining, the drive motor on the roughing machine rotates the fixture and the fixed gear, facilitating machining of various positions on the gear surface. To ensure that the machined area does not overheat and cause deformation or damage to the gear surface, a water pump at the bottom of the roughing machine is typically activated to draw water into a cooling nozzle to cool the machined area. The cooled water falls freely, carrying debris generated during machining into the inner wall of the roughing machine. This results in debris mixed in with the water being drawn into the water pump and causing blockages when the cooled water is recycled, affecting the operation of the cooling system and reducing rough machining efficiency and quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a roughing device for convenient clamping gear processing, including a roughing machine, a mechanical arm is provided on one side of the roughing machine, a cutting tool is installed on the mechanical arm, and a cooling spray pipe is installed through the cutting tool, the other end of the cooling spray pipe is connected to the inner wall of the roughing machine through a water pump, a clamp is provided on one side of the roughing machine, the clamp is driven to rotate by a drive motor provided on the roughing machine, and a filter device is provided on the inner wall of the roughing machine. The filter device can filter and intercept the debris mixed in the used cooling water through the filter screen, so that the cooling water can continue to be recycled. Then, in conjunction with the first scraper and the guide pipe, the filtered debris is discharged, which facilitates the filtration of the filter screen and avoids clogging.

[0006] Preferably, the filtering device includes a filter screen, wherein one end of the filter screen is fixedly installed in the inner wall of the roughing machine, a circular hole is formed on one side of the inner wall of the filter screen, and a groove is formed in the inner wall of the circular hole; a first scraper, wherein one end of the first scraper is installed through and on one side of the inner wall of the filter screen; a servo motor, wherein one side of the servo motor is fixedly installed on one side of the filter screen, and the output end is fixedly installed on one side of the first scraper by means of a coupling; a guide tube, wherein one side of the guide tube is fixedly installed on one side of the filter screen, its inner wall is connected to the inner wall of the circular hole, and the other end is installed through and on the inner wall of the roughing machine; a slide plate, wherein the slide plate is slidably installed in the inner wall of the groove, and its diameter is larger than the inner diameter of the circular hole; a first spring, wherein both ends of the first spring are fixedly installed on one side of the inner wall of the groove and one side of the slide plate, respectively; a stop block, wherein one end of the stop block is slidably installed in the inner wall of the slide plate; and a second spring, wherein both ends of the second spring are fixedly installed on one side of the stop block and one side of the inner wall of the slide plate, respectively.

[0007] The aforementioned components achieve the following effects: During the rough machining process of the gear, the gear is placed on a fixture and fixed in place. Then, the rough machining tool is mounted on the robotic arm of the roughing machine. The drive motor on the robotic arm can be activated to rotate the tool. Simultaneously, the height and angle of the tool can be adjusted by the robotic arm according to the machining requirements, thereby rough machining the surface of the gear. During the machining process, the drive motor on the roughing machine rotates the fixture and the fixed gear, facilitating machining of various positions on the gear surface. At the same time, the water pump on the roughing machine is activated to draw cooling water into the cooling spray pipes and spray it to cool the machined area. The cooled water falls freely and lands on the inner wall of the filter screen, filtering out the metal debris mixed in. Simultaneously, the servo motor is activated to drive the first scraper to rotate counterclockwise, further cleaning the debris that falls onto the inner wall of the filter screen. The metal debris is agitated to facilitate the filtration of cooling water. When the first scraper rotates to a certain angle, one side abuts against the inclined surface of the abutment block, pressing it into the inner wall of the slide plate. This causes the second spring to contract. When it's necessary to remove and clean the metal debris intercepted on the filter screen, the servo motor can be activated to rotate the first scraper clockwise. After rotating to a certain position, it pushes the abutment block towards one end in the circular hole, causing the slide plate to slide towards one end in the groove. This causes the first spring to contract, opening the inner wall of the circular hole. This allows both the metal debris falling onto the slide plate and the metal debris pushed by the first scraper to fall into the circular hole and then be discharged through the guide pipe. This prevents metal debris from accumulating on the filter screen, improving the filtration effect and efficiency of the filter screen. The filtered cooling water can then be reused, facilitating the operation of the cooling system and improving the efficiency and quality of rough machining.

[0008] Preferably, a second scraper is fixedly installed on the outer surface of one end of the first scraper, wherein one side of the second scraper abuts against the inner wall of the filter screen.

[0009] The effect achieved by the above components is as follows: by setting a second scraper, when the servo motor drives the first scraper to rotate, it will also drive the second scraper to rotate in the inner wall of the filter screen, stirring and scraping away the metal debris adhering to the filter screen, avoiding clogging of the filter screen and improving the filtration effect.

[0010] Preferably, a plurality of circular rollers are rotatably mounted on one side of the abutment block, wherein the plurality of circular rollers are arranged at equal intervals.

[0011] The effect achieved by the above components is that by setting up the circular roller, the contact friction between the contact block and the first and second scrapers can be reduced, thereby improving the service life of all three components.

[0012] Preferably, a protective cover is fixedly installed on one side of the filter screen, wherein the servo motor is disposed in the inner wall of the protective cover.

[0013] The effect achieved by the above components is that by setting up a protective cover, the outer surface of the servo motor can be protected, so that the cooling water is not easily washed directly onto the outer surface of the servo motor, thus avoiding damage to the servo motor and improving its service life.

[0014] Preferably, the longitudinal section of the filter screen is trapezoidal, and the size of one end near the bottom of the inner wall of the coarse machine is smaller than that of the other end.

[0015] The effect achieved by the above components is that by setting the longitudinal section of the filter screen to a trapezoidal shape, when metal debris falls onto the filter screen and is intercepted, it will roll towards the center with the inclination angle of the inner wall of the filter screen, reducing the possibility of clogging and improving filtration efficiency and effect.

[0016] Preferably, the inner wall of the guide tube is provided with an auxiliary mechanism, the auxiliary mechanism including a bracket, wherein one side of the bracket is fixedly installed on one side of the guide tube; an electric telescopic rod, wherein one end of the electric telescopic rod is fixedly installed on one side of the bracket; and a circular scraper, wherein the outer surface of the circular scraper is slidably installed in the inner wall of the guide tube, and one side is fixedly installed on the output end of the electric telescopic rod.

[0017] The effect achieved by the above-mentioned components is as follows: by setting an auxiliary mechanism, when the guide tube discharges metal debris, in order to avoid blockage caused by metal debris adhering to the guide tube, the electric telescopic rod on the bracket can be activated to drive the circular scraper to slide back and forth in the inner wall of the guide tube, scraping off the attached metal debris, avoiding accumulation, and facilitating discharge according to the tilt angle of the guide tube, thereby achieving the effect of avoiding blockage.

[0018] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the circular scraper.

[0019] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output end of the electric telescopic rod and the circular scraper can be increased, making the connection more secure, stable, and less prone to breakage or damage.

[0020] The beneficial effects of this utility model are:

[0021] By incorporating a filtration system, cooled water flows freely down and settles on the inner wall of the filter screen, filtering out metal debris. Simultaneously, a servo motor drives the first scraper to rotate counter-clockwise, agitating the metal debris and facilitating its filtration. After rotating to a certain angle, one side of the first scraper abuts against the inclined surface of the abutment block, pressing it into the inner wall of the sliding plate. This causes the second spring to contract. When it's time to remove and clean the metal debris trapped on the filter screen, the servo motor can be activated... The first scraper rotates clockwise. After rotating to a certain position, it pushes the abutment block to move to one end in the round hole, causing the slide plate to slide to one end in the slide groove. This causes the first spring to contract, opening the inner wall of the round hole. This allows metal debris falling on the slide plate and metal debris pushed by the first scraper to fall into the round hole and then be discharged through the guide pipe. This prevents metal debris from accumulating on the filter screen, improves the filtration effect and efficiency of the filter screen, and allows the filtered cooling water to continue to be recycled, facilitating the operation of the cooling system and improving the efficiency and quality of rough machining.

[0033] Figure 1-7 The diagram illustrates a roughing device for convenient clamping gear machining, comprising a roughing machine 1. A robotic arm 3 is mounted on one side of the roughing machine 1, with a cutting tool installed on the robotic arm 3. A cooling spray pipe is installed through the cutting tool, and the other end of the cooling spray pipe is connected to the inner wall of the roughing machine 1 via a water pump. A clamp 4 is mounted on one side of the roughing machine 1, driven to rotate by a drive motor mounted on the roughing machine 1. A filter device 2 is installed on the inner wall of the roughing machine 1. The filter device 2 uses a filter screen 21 to filter and intercept debris mixed in with the used cooling water, allowing the cooling water to be reused. Then, in conjunction with a first scraper 23 and a guide pipe 25, the filtered debris is discharged, facilitating filtration by the filter screen 21 and preventing clogging. It should be noted that the robotic arm 3 and the clamp 4 are mature technologies and equipment in the prior art, and their internal structure, connection method, and principle will not be described further.

[0034] Figure 1-7The filter device 2 shown includes a filter screen 21, one end of which is fixedly installed on the outer surface of the filter screen 21 within the inner wall of the roughing machine 1. A circular hole 24 is formed on one side of the inner wall of the filter screen 21, and a groove 27 is formed on the inner wall of the circular hole 24. A first scraper 23 is also included, one end of which is installed through the filter screen 21 on one side. A servo motor 22 is fixedly installed on one side of the filter screen 21, and its output end is fixedly installed on one side of the first scraper 23 via a coupling. A guide pipe 25 is also included, one side of which is fixedly installed on one side of the filter screen 21. Its inner wall is connected to the inner wall of the circular hole 24, while the other end is installed through the inner wall of the roughing machine 1; the slide plate 28 is slidably installed in the inner wall of the slide groove 27, and its diameter is larger than the inner diameter of the circular hole 24; the first spring 29 is fixedly installed on one side of the inner wall of the slide groove 27 and one side of the slide plate 28 respectively; the abutment block 210 is slidably installed in the inner wall of the slide plate 28 at one end; the second spring 211 is fixedly installed on one side of the abutment block 210 and one side of the inner wall of the slide plate 28 respectively.During the rough machining process of the gear, the gear is placed on the fixture 4 and fixed in place. Then, the rough machining tool is mounted on the robotic arm 3 of the rough turning machine 1. The drive motor on the robotic arm 3 can be started to rotate the tool. At the same time, the height and angle of the tool can be adjusted by the robotic arm 3 according to the machining requirements to perform rough machining on the surface of the gear. During the machining process, the drive motor on the rough turning machine 1 drives the fixture 4 and the fixed gear to rotate, which facilitates the machining of various parts of the gear surface. At the same time, the water pump on the rough turning machine 1 is started to draw the internal cooling water into the cooling spray pipe and spray it to cool the machined area. The cooled water will fall freely and then fall into the inner wall of the filter screen 21, filtering out the metal debris mixed in with it. At the same time, the servo motor 22 is started to drive the first scraper 23 to rotate counterclockwise, agitating the metal debris that has fallen into the inner wall of the filter screen 21, so as to facilitate the filtration of the cooling water. At this point, after the first scraper 23 rotates to a certain angle, one side will abut against the inclined surface of the abutment block 210, pressing it into the inner wall of the slide plate 28, causing the second spring 211 to contract. When it is necessary to discharge and clean the metal debris intercepted on the filter screen 21, the servo motor 22 can be started to drive the first scraper 23 to rotate clockwise. After rotating to a certain position, it will push the abutment block 210 to move to one end in the round hole 24, causing the slide plate 28 to slide to one end in the slide groove 27, causing the first spring 29 to contract and open the inner wall of the round hole 24. This will allow the metal debris falling on the slide plate 28 and the metal debris pushed by the first scraper 23 to fall into the round hole 24 and then be discharged through the guide pipe 25, avoiding the accumulation of metal debris on the filter screen 21, improving the filtration effect and efficiency of the filter screen 21, and allowing the filtered cooling water to continue to be recycled, facilitating the operation of the cooling system and improving the efficiency and quality of rough processing.

[0035] Figure 1-7 A second scraper 213 is fixedly mounted on the outer surface of one end of the first scraper 23, with one side of the second scraper 213 abutting against the inner wall of the filter screen 21. By setting the second scraper 213, when the servo motor 22 drives the first scraper 23 to rotate, it also rotates within the inner wall of the filter screen 21, stirring and scraping away metal debris adhering to the filter screen 21, preventing clogging and improving the filtration effect. Several circular rollers 212 are rotatably mounted on one side of the abutment block 210, arranged at equal intervals. By setting the circular rollers 212, the frictional force between the abutment block 210 and the first scraper 23 and the second scraper 213 can be reduced, improving the service life of all three components.

[0036] Figure 1-7A protective cover 214 is fixedly installed on one side of the filter screen 21, and the servo motor 22 is disposed in the inner wall of the protective cover 214. By setting the protective cover 214, the outer surface of the servo motor 22 is protected, preventing cooling water from directly washing onto the outer surface of the servo motor 22, thus avoiding damage to the servo motor 22 and improving its service life. The longitudinal section of the filter screen 21 is trapezoidal, and the dimension of one end near the bottom of the inner wall of the coarse mill 1 is smaller than that of the other end. By setting the longitudinal section of the filter screen 21 to a trapezoidal shape, when metal debris falls onto the filter screen 21 and is intercepted, it will roll towards the center with the inclination angle of the inner wall of the filter screen 21, reducing the possibility of clogging and improving filtration efficiency and effect.

[0037] Figure 1-7 The inner wall of the guide pipe 25 shown is provided with an auxiliary mechanism 26. The auxiliary mechanism 26 includes a bracket 261, one side of which is fixedly installed on one side of the guide pipe 25; an electric telescopic rod 262, one end of which is fixedly installed on one side of the bracket 261; and a circular scraper 263, the outer surface of which is slidably installed in the inner wall of the guide pipe 25, and one side is fixedly installed on the output end of the electric telescopic rod 262. By setting the auxiliary mechanism 26, when the guide pipe 25 discharges metal debris, in order to avoid blockage caused by metal debris adhering to the guide pipe 25, the electric telescopic rod 262 on the bracket 261 can be activated to drive the circular scraper 263 to slide back and forth in the inner wall of the guide pipe 25, scraping off the attached metal debris, preventing accumulation, and facilitating discharge according to the tilt angle of the guide pipe 25, thus achieving the effect of avoiding blockage. A reinforcing rod 264 is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic pole 262, and one side of the reinforcing rod 264 is fixedly installed on one side of the circular scraper 263. By setting the reinforcing rod 264, the connection area between the output end of the electric telescopic pole 262 and the circular scraper 263 can be increased, making the connection more firm, stable and less prone to breakage or damage.

[0038] Working Principle: Existing roughing machines 1 are equipped with a special clamping fixture 4 to hold the gears to be machined, enabling rapid cutting of the gear blank. Therefore, the roughing machine 1 itself facilitates gear clamping and fixation. During rough machining, the gear is placed on the clamping fixture 4 for fixed positioning. Then, the roughing tool is mounted on the robotic arm 3 on the roughing machine 1. The drive motor on the robotic arm 3 can be activated to rotate the tool. Simultaneously, the height and angle of the tool on the robotic arm 3 can be adjusted according to machining requirements to perform rough machining on the gear surface. During machining, the drive motor on the roughing machine 1 rotates the clamping fixture 4 and the fixed gear, facilitating machining of various parts of the gear surface. Simultaneously, the water pump on the roughing machine 1 draws internal cooling water into cooling spray pipes to cool the machined area. The cooled water falls freely and lands on the inner wall of the filter screen 21, filtering out metal debris. At the same time, the servo motor 22 is activated to drive... The first scraper 23 rotates counterclockwise to agitate the metal debris falling into the inner wall of the filter screen 21, facilitating the filtration of cooling water. After rotating to a certain angle, one side of the first scraper 23 will abut against the inclined surface of the abutment block 210, pressing it into the inner wall of the slide plate 28, causing the second spring 211 to contract. When it is necessary to discharge and clean the metal debris intercepted on the filter screen 21, the servo motor 22 can be activated to drive the first scraper 23 to rotate clockwise. After rotating to a certain position, it will push the abutment block 210 in a circular motion. The movement of the slide plate 28 in the groove 27 causes the first spring 29 to contract, opening the inner wall of the circular hole 24. This allows metal debris falling onto the slide plate 28 and the metal debris pushed by the first scraper 23 to fall into the circular hole 24 and then be discharged through the guide pipe 25. This prevents metal debris from accumulating on the filter screen 21, improving the filtration effect and efficiency of the filter screen 21. It also allows the filtered cooling water to be reused, facilitating the operation of the cooling system and improving the efficiency and quality of rough machining. To prevent blockage caused by metal debris adhering to the guide pipe 25, the electric telescopic rod 262 on the bracket 261 can be activated to drive the circular scraper 263 to slide back and forth within the inner wall of the guide pipe 25, scraping off any attached metal debris. This prevents accumulation and facilitates discharge as the guide pipe 25 tilts, thus avoiding blockage.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
