Description

Technical Field

[0001] This invention relates to the field of motor shaft drilling technology, specifically to an automatic motor shaft hole processing device. Background Technology

[0002] Drilling machines are mechanical devices that use tools with superior hardness and sharpness to the target workpiece to process cylindrical holes on the workpiece surface through rotary cutting or rotary extrusion. They can precisely drill holes in precision components such as motor spindles to meet various assembly and functional requirements. Based on the degree of automation, they can be divided into semi-automatic and fully automatic types. With the continuous rise in labor costs in the manufacturing industry, fully automatic drilling machines have become a core technology upgrade direction for most enterprises. In the field of automated drilling of motor spindles, existing fully automatic drilling machines mainly adopt vertical and horizontal processing layouts. The core process involves clamping the motor spindle with tooling fixtures and continuously spraying grinding fluid during the drilling process to lubricate and cool the cutting area, ultimately completing the hole processing. However, when using a horizontal layout, there are a series of overlapping process defects and environmental problems, which seriously restrict processing quality, efficiency, and the safety of the working environment.

[0003] However, when drilling the motor spindle using a horizontal machining method, existing equipment has significant process defects and environmental problems: the cutting fluid nozzles are arranged at a fixed angle, which is only suitable for the initial stage when the tool just contacts the workpiece. At this time, the cutting zone is exposed. A 45° tilted nozzle can accurately spray fluid to cool and remove chips, but after the tool goes deeper, the space inside the hole is closed, and the cutting fluid is easily blocked by the hole wall and cannot reach the cutting zone at the bottom of the hole, resulting in insufficient cooling, accelerated tool wear, and chips adhering to the drill bit's spiral groove. At the same time, the horizontal placement of the spindle after drilling causes accumulation in the deep part of the hole. Fine chips and spun chips are stuck due to the lack of gravity guidance, and incomplete cleaning can easily cause assembly jamming and reduce the stability of motor operation. In addition, the rotation of the drill bit will throw the cutting fluid and waste chips to the surrounding area of ​​the equipment. The oil mist formed by the atomization of the cutting fluid pollutes the air, which not only does not meet environmental protection standards and endangers the health of operators, but also increases the cleaning cost of the workshop. The accumulation of metal waste chips can also easily cause equipment jamming. Summary of the Invention

[0004] Technical problems to be solved This invention provides an automatic machining equipment for motor shaft holes, which solves the problems of the fixed angle of the cutting fluid nozzle causing the cooling and chip removal effect to decrease with the hole depth when machining the motor spindle channel horizontally, the stubborn retention of waste material in the hole due to the horizontal posture, and the splashing and atomization of cutting fluid and waste chips polluting the environment, endangering personnel health, and easily causing equipment jamming.

[0005] Technical solution To improve the machining accuracy and efficiency of horizontal drilling of motor spindles, reduce tool wear, reduce waste residue in the hole, improve the workshop working environment, protect the health of operators and the stability of equipment operation, the present invention achieves this through the following technical solution: an automatic machining equipment for motor shaft holes, including a feeding slide table and a collection box installed on one side of the bottom of the feeding slide table, and an adjustment component installed on one side of the top of the feeding slide table; The adjustment assembly includes a protective cover and a connecting pipe that passes through and is fixedly connected to one side of the protective cover. A nozzle is installed at one end of the connecting pipe that passes through the protective cover. An electric actuator is installed on one side of the top of the protective cover. The output end of the electric actuator passes through the protective cover and is fixedly connected to a U-shaped connecting plate. A guide frame is rotatably connected to the bottom of the inner cavity of the U-shaped connecting plate. Hinges are installed on both sides of the top of the guide frame. An annular plate is fitted on the outer wall of the nozzle. A swing rod is rotatably connected to both sides of the annular plate, and the other end of the swing rod is rotatably connected to the hinge to achieve the angle of the cutting fluid spray. Both sides of the guide frame are fixedly connected to guide plates one, and a connecting rod is fixedly connected to one side of the top of the inner cavity of the guide frame. Two guide plates two are rotatably connected to the outer wall of the connecting rod to guide the cutting fluid after it is sprayed out.

[0006] Furthermore: a swing plate is fixedly connected to the bottom of each of the two guide plates, and a square frame plate is fixedly connected to the top of each of the two swing plates. A mounting plate is fixedly connected to one side of the bottom of the guide plate. A groove is formed through the middle of the mounting plate. A mounting cover is fixedly connected to the top of the mounting plate. A mounting cover is fixedly connected to one side of the mounting cover. A motor is installed in the inner cavity of the mounting cover. The output end of the motor passes through the mounting cover and is rotatably connected to a bidirectional lead screw. The square frame plate passes through the groove and slides on the outer wall of the bidirectional lead screw. Two sets of threaded connecting plates are slidably connected to both sides of the outer wall of the bidirectional lead screw.

[0007] Furthermore, each set of threaded connecting plates consists of two plates located on either side of the square frame plate.

[0008] Furthermore: an electric actuator second is installed on the top side of the protective cover away from the electric actuator first. The output end of the electric actuator second passes through the protective cover and is fixedly connected to a connecting pipe second. The connecting pipe second passes through the connecting pipe first and is slidably connected. A nozzle second is installed on the bottom side of the connecting pipe second.

[0009] Furthermore: a flow channel is provided on one side of the upper part of the outer wall of the second connecting pipe, and the flow channel communicates with the first connecting pipe; and grooves are provided on both sides of the lower part of the outer wall of the second connecting pipe, and the grooves cooperate with the first connecting pipe.

[0010] Furthermore: a first baffle plate is fixedly connected to the inner cavity of the protective cover, and a second baffle plate is fixedly connected to the side of the inner cavity of the protective cover away from the first baffle plate. A circular groove is respectively opened in the middle part of the first baffle plate and the second baffle plate.

[0011] Furthermore: a slide rail mounting platform is installed on one side of the unloading slide rail table, and a drilling device is installed on the top of the slide rail mounting platform.

[0012] Furthermore, a circular groove is provided on one side of the outer wall of the protective cover, and the circular groove cooperates with the drilling equipment.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a triangularly arranged guide plate II within a guide frame, along with two guide plates I on either side, to create a fluid flow guiding pressure difference with the spiral groove of the cutting tool. This, combined with an angle adjustment mechanism consisting of a control system, an electric actuator I, a swing rod, and a hinged seat on the slide rail mounting platform, enables the cutting fluid to converge along the tangential direction of the spiral groove. The control system drives the electric actuator I to adjust the tilt angle of the guide frame based on real-time hole depth data, ensuring the cutting fluid reaches the core area at the bottom of the hole. The fluid flow directly acts on the cutting contact surface at the bottom of the hole, completely solving the problems of fluid attenuation with hole depth and insufficient cooling in deep hole areas associated with traditional nozzles. This allows the cutting fluid to fully cover the cutting edge to the bottom of the hole, significantly improving the machining accuracy of deep holes.

[0014] This invention starts the motor through the control system on the slide rail mounting platform. Combined with the guide plate gathering mechanism composed of a two-way lead screw, a threaded connecting plate, and a square frame plate, the guide plate II is tapered and gathered. The cutting fluid forms a columnar liquid flow that directly rushes towards the debris in the hole. Then, the connecting pipe II is driven to move downward by the electric push rod II. Together with the tool cleaning system composed of the flow channel and the nozzle II, the debris on the outer wall of the tool is cleaned. This completely solves the problems of debris retention in the hole and incomplete cleaning of tool adhesion after traditional machining, and improves the cleanliness of the hole and the reusability of the tool.

[0015] This invention utilizes a second baffle plate, a first baffle plate, and a circular groove mounted on a slide rail mounting platform. These, along with the second circular groove in the feed path of the drilling equipment, create a closed-loop constraint for the cutting fluid and chips. When the drilling equipment contacts the motor shaft via the second circular groove and the first circular groove of the second baffle plate, the second baffle plate and the first baffle plate form a semi-enclosed space. This confines the flowing cutting fluid and chips within this space, completely solving the problems of cutting fluid splashing and chip scattering during traditional horizontal drilling. It avoids the formation of oil mist from the atomization of cutting fluid, which pollutes the workshop air and harms the health of operators. It also prevents equipment jamming caused by chip accumulation, reduces workshop cleaning and maintenance costs, and improves the safety and standardization of the working environment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1-9In this embodiment of the invention, an automatic machining equipment for motor shaft holes provided by the present invention, through the triangular arrangement of the second guide plate 212 in the guide frame 206 and the first guide plate 210 on both sides, forms a liquid flow guiding pressure difference with the spiral groove of the tool. In conjunction with the control system on the slide rail mounting table 5, the electric push rod 204, the swing rod 209 and the hinge seat 207 form an angle adjustment mechanism to realize the convergence of cutting fluid along the tangential direction of the spiral groove. The control system drives the electric push rod 204 to adjust the tilt angle of the guide frame 206 according to the real-time data of the hole depth, so that the cutting fluid reaches the core area at the bottom of the hole directly. The liquid flow directly acts on the cutting contact surface at the bottom of the hole, which completely solves the problem of the traditional nozzle attenuation with the hole depth and insufficient cooling in the deep hole area. It drives the cutting fluid to fully cover from the cutting edge to the bottom of the hole, which greatly improves the machining accuracy of deep holes. Then, the motor 219 is started by the control system on the slide rail mounting platform 5. The guide plate gathering mechanism, which consists of a two-way lead screw 220, a threaded connecting plate 221, and a square frame plate 214, causes the guide plate 212 to gather in a conical shape. The cutting fluid forms a columnar liquid flow that directly rushes the debris in the hole. Then, the connecting pipe 301 is driven to move down by the electric push rod 3. With the tool cleaning system consisting of the flow channel 302 and the nozzle 304, the debris on the outer wall of the tool is cleaned. This completely solves the problem of debris retention in the hole and incomplete cleaning of tool adhesion after traditional machining, and improves the cleanliness of the channel and the reusability of the tool. Furthermore, by using the baffle plate 401, baffle plate 4, and circular groove installed on the slide rail mounting platform 5, in conjunction with the circular groove 502 in the feed path of the drilling equipment 501, the cutting fluid and waste chips are effectively contained and constrained. When the drilling equipment 501 contacts the motor 219 shaft via the circular groove 502 and the circular groove 402 of the baffle plate 401, the baffle plate 401 and the baffle plate 4 form a semi-enclosed space, which restricts the flow of cutting fluid and waste chips during drilling to flow within this space. This completely solves the problem of cutting fluid splashing and waste chip scattering during traditional horizontal drilling. It avoids the formation of oil mist from cutting fluid atomization that pollutes the workshop air and harms the health of operators, and also prevents the equipment jamming hazard caused by the accumulation of waste chips. At the same time, it reduces the workshop cleaning and maintenance costs and improves the safety and standardization of the working environment.

[0020] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0021] In this embodiment, the system includes a feeding slide rail 1 and a collection box 2 installed on one side of the bottom of the feeding slide rail 1. An adjustment component is installed on one side of the top of the feeding slide rail 1. The unloading slide rail 1 is equipped with a roller conveyor assembly. The automatic loading and unloading of the motor shaft is achieved by the rolling of the rollers. The motor shaft to be processed can automatically slide into the processing station along the inclined rollers. After processing, it can also slide out quickly through the rollers without manual handling, which improves the loading and unloading efficiency. At the same time, the unloading slide rail 1 is also equipped with a pneumatic positioning and clamping mechanism. When the motor shaft is conveyed to the processing station by the rollers, the mechanism will position and clamp the outer wall of the motor shaft, fixing the motor shaft in the processing position corresponding to the drilling tool 501, preventing the motor shaft from shifting during the drilling process and ensuring drilling accuracy. After processing, the clamping mechanism automatically releases and falls into the collection box 2, realizing the automation of conveying, clamping, and unloading. This is existing technology and will not be described in detail here. The adjustment assembly includes a protective cover 201 and a connecting pipe 202 that passes through and is fixedly connected to one side of the protective cover 201. A nozzle 203 is installed at one end of the connecting pipe 202 that passes through the protective cover 201. An electric actuator 204 is installed on one side of the top of the protective cover 201. The output end of the electric actuator 204 passes through the protective cover 201 and is fixedly connected to a U-shaped connecting plate 205. A guide frame 206 is rotatably connected to the bottom of the inner cavity of the U-shaped connecting plate 205. Hinges 207 are installed on both sides of the top of the guide frame 206. An annular plate 208 is sleeved on the outer wall of the nozzle 203. A swing rod 209 is rotatably connected to both sides of the annular plate 208, and the other end of the swing rod 209 is rotatably connected to the hinge 207 to achieve the angle of the cutting fluid spray. Among them, the cutting fluid storage tank and pump body installed in conjunction with the connecting pipe 202 realize the continuous and stable supply of cutting fluid. The cutting fluid storage tank provides sufficient lubricating medium reserves for drilling operations, avoiding frequent fluid replenishment and interruption of processing. The pump body provides stable power for cutting fluid delivery. This is existing technology and will not be elaborated here. Both sides of the guide frame 206 are fixedly connected to the guide plate 210, and the top side of the inner cavity of the guide frame 206 is fixedly connected to the connecting rod 211. The outer wall of the connecting rod 211 is rotatably connected to two guide plates 212 to guide the cutting fluid after it is sprayed out. Two guide plates 212 are fixedly connected to the bottom of each of the two guide plates 213. Square frame plates 214 are fixedly connected to the top of each of the two guide plates 213. A mounting plate 215 is fixedly connected to one side of the bottom of the guide frame 206. A groove 216 is provided through the middle of the mounting plate 215. A mounting cover 217 is fixedly connected to the top of the mounting plate 215. A mounting cover 218 is fixedly connected to one side of the mounting cover 217. A motor 219 is installed in the inner cavity of the mounting cover 218. The output end of the motor 219 passes through the mounting cover 217 and is rotatably connected to a two-way screw 220. The square frame plate 214 passes through the groove 216 and slides on the outer wall of the two-way screw 220. Two sets of threaded connecting plates 221 are slidably connected to both sides of the outer wall of the two-way screw 220. Each set of threaded connecting plates 221 consists of two plates located on both sides of the square frame plate 214. The groove in the middle of the square frame plate 214, in conjunction with the driving action of the threaded connecting plate 221, provides the square frame plate 214 with a space to move and avoid obstacles. When the threaded connecting plate 221 moves the square frame plate 214 closer, the groove can avoid the installation area of ​​the bidirectional screw 220, thus preventing the square frame plate 214 from interfering with or getting stuck with the bidirectional screw 220 during the movement, and ensuring the smoothness of the retraction action of the guide plate 212. Electric actuator 204 is installed on the top side of the protective cover 201 away from the electric actuator 204. The output end of the electric actuator 204 passes through the protective cover 201 and is fixedly connected to the connecting pipe 201. The connecting pipe 201 passes through the connecting pipe 202 and is slidably connected. The nozzle 204 is installed on the bottom side of the connecting pipe 201. Among them, the sealing end is installed at the sliding fit position of the connecting pipe 2 301 and the connecting pipe 1 202 to achieve sealing and leakage prevention during the cutting fluid delivery process: the sealing end can closely fit the outer wall of the connecting pipe 2 301 and the inner wall of the connecting pipe 1 202, which not only ensures the flexibility of the connecting pipe 2 301 to slide up and down to adjust its position, but also prevents the cutting fluid from leaking from the sliding gap. A flow channel 302 is provided on one side of the upper part of the outer wall of the second connecting pipe 301, and the flow channel 302 communicates with the first connecting pipe 202. A groove 303 is provided on both sides of the lower part of the outer wall of the second connecting pipe 301, and the groove 303 cooperates with the first connecting pipe 202. During the drilling stage of the motor shaft, the groove 303 moves upward with the second connecting pipe 301 and is embedded in the inner cavity of the first connecting pipe 202, serving as the core guide channel for the cutting fluid to flow from the first connecting pipe 202 to the nozzle 203, ensuring that the cutting fluid is accurately delivered to the guide frame 206 to cover the machining area of ​​the tool and the motor shaft. Among them, the function of the flow channel 302 is in the tool cleaning stage after the drilling equipment 501 is reset. The flow channel 302 moves down with the second connecting pipe 301 to the inner cavity of the first connecting pipe 202, and serves as a guide channel for the cutting fluid to flow from the first connecting pipe 202 to the inside of the second connecting pipe 301. After the cutting fluid enters the second connecting pipe 301 through the channel, it is sprayed out by the second nozzle 304, which accurately covers the outer wall of the tool to clean residual debris and adhering materials, thus realizing a dedicated fluid flow path for tool cleaning after processing. A baffle plate 4 is fixedly connected to the inner cavity of the protective cover 201. A baffle plate 401 is fixedly connected to the side of the inner cavity of the protective cover 201 away from the baffle plate 4. A circular groove 402 is respectively opened in the middle part of the baffle plate 4 and the baffle plate 401. Among them, the diameter of the circular groove 402 is adapted to the outer diameter of the tool of the drilling equipment 501 and the machining position size of the motor shaft, providing a channel for the drilling equipment 501 to feed to the motor shaft through the circular groove 502, ensuring the smoothness of the feeding action of the drilling equipment 501. At the same time, the machining area of ​​the tool and the motor shaft is limited to the inside of the circular groove 402. With the help of the baffle plate 401 and the baffle plate 4, the semi-enclosed space formed can restrain the cutting fluid splashed and the scattered waste during the drilling process in the surrounding area of ​​the groove, preventing the cutting fluid from atomizing and spreading and the waste from falling randomly. A slide rail mounting platform 5 is installed on one side of the unloading slide rail table 1, and a drilling device 501 is installed on the top of the slide rail mounting platform 5. Among them, the drilling equipment 501 is equipped with a motor 219 for driving the rotation of the cutting tool and a cutting tool chuck, which are existing technologies and will not be described in detail here; A circular groove 502 is provided on one side of the outer wall of the protective cover 201, and the circular groove 502 cooperates with the drilling device 501.

[0022] When using the automatic motor shaft hole processing equipment of this embodiment to perform drilling operations on the motor shaft, the drilling device 501 is started first, and then the cylinder mounted on the top of the slide rail mounting table 5 is started to push the drilling device 501 forward through the circular groove 2 502, and then through the circular groove 1 402 opened in the middle of the baffle plate 2 401 to contact the motor shaft. Before the drilling device 501 moves, the electric push rod 2 3 is activated first, which drives the connecting pipe 2 301 to move upward, so that the groove 2 303 on the outer wall of the connecting pipe 2 301 is embedded into the inner cavity of the connecting pipe 1 202. Then the electric push rod 2 3 stops moving to avoid the drilling device 501 from interfering with the groove 2 502 during feeding. Interference occurs at 303. At this time, one end of the connecting pipe 202 is connected to the cutting fluid tank. The cutting fluid is delivered to the connecting pipe 202 through the pump. After the cutting fluid is guided by the groove 303, it is sprayed into the inner cavity of the guide frame 206 by the nozzle 203. At this time, the guide frame 206 is at a 45-degree angle, which can guide the cutting fluid to the initial contact area between the tool and the motor shaft of the drilling equipment 501. This angle ensures that the cutting fluid accurately covers the cutting edge of the tool and can quickly remove the debris generated by the initial cutting with the thrust of the oblique liquid flow. At the same time, it efficiently wraps the cutting edge to achieve cooling and avoids wear of the tool due to local overheating in the early stage of processing. After the cutting fluid is sprayed into the guide frame 206, it will first be dispersed to both sides by the guide plate 212 arranged in a triangular angle. The dispersed cutting fluid will then come into contact with the guide plate 210 on both sides of the guide frame 206. The guide plate 210 will adjust the flow angle to be along the tangential direction of the tool spiral groove, so that the cutting fluid on both sides is sprayed to the gap between the side wall of the tool spiral groove and the hole wall, so that the cutting fluid can fully cover the entire cutting edge of the tool, enhance the lubrication and cooling effect in the deep groove area, and simultaneously flush away the fine chips adhering to the hole wall with the tangential thrust of the liquid flow, so as to prevent the chips from accumulating and agglomerating in the spiral groove. As the tool continues to feed and the depth of the motor shaft hole gradually increases, the control system on the slide rail mounting table 5 will activate the electric push rod 204 to drive the U-shaped connecting plate 205 to move downward based on the real-time hole depth data. During the downward movement of the U-shaped connecting plate 205, the swing rod 209 connected to both sides of the outer wall of the nozzle 203 will be linked to adjust the tilt angle of the guide frame 206 through the hinge seat 207. As the hole depth continues to increase, the U-shaped connecting plate 205 gradually descends, causing the guide frame 206 to deflect from the initial 45 degrees into the hole, eventually forming a guide posture that fits the hole opening orientation, aligning with the core cutting area of ​​the tool and the bottom of the motor shaft hole, ensuring that the cutting fluid can still reach the processing area directly during deep hole machining, and providing targeted cooling for the cutting edge of the tool and the cutting contact surface at the bottom of the hole, while maintaining the unobstructed chip removal channel in the hole. After drilling is completed, the drilling equipment 501 is reset by retracting the cylinder on the top of the slide rail mounting platform 5. During the reset process of the drilling equipment 501, the motor 219 is started by the control system installed on the top of the slide rail mounting platform 5. When the motor 219 is running, it will drive the bidirectional lead screw 220 to rotate. During the rotation of the bidirectional lead screw 220, it will drive the two sets of threaded connecting plates 221 to move closer to the middle along the lead screw, and then drive the two square frame plates 214 to move closer to each other. The square frame plates 214 synchronously pull the swing plate 213 to move closer. Finally, the swing plate 213 will bring the two guide plates 212 together into a conical shape. At this time, the cutting fluid discharged by the guide frame 206 will form a concentrated columnar liquid flow, which will be delivered to the hole to wash away the residual debris and garbage in the hole. After the washing is completed, the electric push rod 204 drives the U-shaped connecting plate 205 to reset. At the same time, the guide frame 206 is reset to the initial 45-degree tilt state through the linkage of the swing rod 209 and the hinge seat 207, preparing for the next drilling. After the drilling equipment 501 is reset, the control system causes the electric actuator 2 3 to push the connecting tube 2 301 downward. The connecting tube 2 301 slides along the inner cavity of the connecting tube 1 202. When the flow groove 302 on the outer wall of the connecting tube 2 301 is completely inside the connecting tube 1 202, the electric actuator 2 3 stops moving. At this time, the cutting fluid enters the connecting tube 2 301 through the flow groove 302 and is finally sprayed out through the nozzle 2 304. The sprayed cutting fluid just covers the outer wall of the tool and thoroughly cleans the residual debris and cutting fluid adhering to the tool surface. It should be noted that the slide rail mounting platform 5 is equipped with a PLC control system for collecting hole depth data and controlling the operation of the equipment. The control system controls the start-stop and operation logic of actuators such as cylinders, electric actuators, and motors 219. This is existing technology and will not be elaborated on here.
