Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a drilling fixture for irregularly shaped motor shaft tubes based on CNC cutting tools. Background Technology

[0002] Axle tubes are common front fork mounting devices on vehicles, used to install shock absorbers to reduce vehicle vibration. A special-shaped axle tube is an axle tube with a special-shaped flange at one end.

[0003] Patent publication number CN220591656U relates to a drilling fixture for irregularly shaped shaft tubes, belonging to the technical field of irregularly shaped tube machining equipment. It includes a drilling machine worktable with two support plates spaced horizontally at the top. A three-jaw chuck is fixedly mounted on the top of one support plate, and a rotating shaft is rotatably mounted on the top of the other support plate. The rotating shaft is coaxial with the clamping hole of the three-jaw chuck. A shaft locking mechanism for locking the rotating shaft is fitted at the end of the rotating shaft away from the three-jaw chuck, and the shaft locking mechanism is fixedly connected to the support plate. A fixing mechanism is installed at the end of the rotating shaft facing the three-jaw chuck, including a cover plate fixedly connected coaxially to the rotating shaft. This drilling fixture for irregularly shaped shaft tubes, through the coordinated arrangement of the fixing mechanism and the clamping mechanism, facilitates the clamping of irregularly shaped shaft tubes with different shaped flanges, improving the machining accuracy and efficiency of irregularly shaped shaft tubes.

[0004] In the aforementioned patent, the combination of a fixing mechanism and a clamping mechanism facilitates the clamping of irregularly shaped shaft tubes with different flange shapes, improving the processing accuracy and efficiency of the irregularly shaped shaft tubes. However, when the drill bit drills downwards, excessive downward pressure can cause shaft deformation, affecting the drilling of the shaft tube. Furthermore, if the drilling coolant is not drained in time, bacteria can grow inside the equipment, affecting the internal environment of the machine casing. Additionally, the coolant sprayed during drilling mixes with debris, hindering subsequent cleaning. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drilling fixture for irregularly shaped motor shafts based on CNC cutting tools, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling fixture for irregularly shaped motor shaft tubes based on CNC cutting tools, comprising: a base, a housing, the housing being fixedly mounted on the top of the base; a rotating door, the rotating door being rotatably mounted on the inner wall of the housing; a drilling device, the drilling device being disposed on the top of the inner wall of the housing, a drainage hole being provided at the bottom of the base, and a cooling device being provided on the drilling device; an electric push rod, the electric push rod being fixedly mounted on the inner wall of the housing; a rotary motor being fixedly mounted on the output end of the electric push rod, the output end of the rotary motor having a slot for clamping and limiting the shaft tube; and the drilling... A connecting rod is fixedly installed on the surface of the equipment. A slide rail is fixedly installed on the inner wall of the chassis. A slider is slidably installed on the surface of the slide rail. A slide plate is slidably installed on the surface of the slider. The end of the connecting rod away from the drilling equipment is slidably installed on the inner wall of the slide plate. A support frame is provided on the top of the slide plate. An L-shaped rod is fixedly installed on the output end of the electric push rod. A U-shaped frame is fixedly installed on the end of the L-shaped rod away from the electric push rod. A trapezoidal pulley frame is fixedly installed on the surface of the slide plate. The movement of the U-shaped frame towards each other will push the trapezoidal pulley frame to move upward. The upward movement of the trapezoidal pulley frame will drive the slide plate to move upward. The upward movement of the slide plate will drive the support frame to move upward.

[0007] According to the above technical solution, a first spring is provided between the slider and the slide plate. The slide plate is reset by the elastic force of the first spring itself. The U-shaped frame is set below the trapezoidal pulley frame.

[0008] According to the above technical solution, the chassis is equipped with a flow guiding device and a separation device. The flow guiding device includes a long plate, a sliding connecting plate, a connecting rope, and a rotating plate. The long plate moves upward by moving the trapezoidal pulley frame upward, which in turn moves the sliding connecting plate upward, which in turn pulls the connecting rope upward. The long plate is fixedly installed on the surface of the trapezoidal pulley frame. The sliding connecting plate is slidably installed on the inner wall of the chassis. The sliding connecting plate is slidably connected to the long plate. The connecting rope is fixedly installed at the bottom of the sliding connecting plate. The rotating plate is rotatably installed on the inner wall of the chassis. The end of the connecting rope away from the sliding connecting plate is fixedly installed at the top of the rotating plate.

[0009] According to the above technical solution, a connecting frame is fixedly installed on the top of the sliding connecting plate, an air blower is provided on the inner wall of the chassis, an air blowing port is opened on the surface of the air blower, and a sealing plate is slidably installed on the surface of the air blowing port. When the sliding connecting plate moves upward, it will drive the connecting frame to move upward, and when the connecting frame moves upward, it will push the sealing plate to move upward. When the sealing plate moves upward, it will disengage from the seal on the air blowing port.

[0010] According to the above technical solution, a second spring is provided between the sliding connecting plate and the chassis, and the sliding connecting plate is reset by the elastic force of the second spring. A first torsion spring is provided between the rotating plate and the chassis, and the rotating plate is reset by the elastic force of the first torsion spring. A third spring is provided between the air outlet and the sealing plate, and the sealing plate is reset by the elastic force of the third spring.

[0011] According to the above technical solution, the separation device includes a pulley frame, a long slide plate, a screening frame, and a round rod. The pulley frame is released from pressure by the upward rotation of the rotating plate, and the pulley frame is moved upward by the elastic force of the No. 4 spring. The upward movement of the pulley frame releases the pressure on the screening frame. The pulley frame is slidably installed on the inner wall of the base, the long slide plate is slidably installed on the inner wall of the base, the screening frame is slidably installed on the surface of the long slide plate, and the round rod is fixedly installed on the top of the screening frame.

[0012] According to the above technical solution, an L-shaped plate is fixedly installed on the inner wall of the base, a sliding plate is slidably installed on the inner wall of the screening frame, and a trapezoidal frame is fixedly installed on the surface of the sliding plate. Pushing the trapezoidal frame toward the center of the screening frame will cause the sliding plate to push toward the center of the screening frame. When the screening frame is reset after processing is completed, the trapezoidal frame will lose its squeezing and cause the sliding plate to reset.

[0013] According to the above technical solution, a No. 4 spring is provided between the pulley frame and the base, and the pulley frame is reset by the elastic force of the No. 4 spring itself. A No. 5 spring is provided between the long slide plate and the base, and the long slide plate is reset by the elastic force of the No. 5 spring itself. A No. 6 spring is provided between the screen frame and the sliding plate, and the sliding plate is reset by the elastic force of the No. 6 spring itself.

[0014] This invention provides a drilling fixture for irregularly shaped motor shafts based on CNC cutting tools. It has the following advantages: (1) This invention places the shaft tube in the slot and limits the shaft tube to prevent it from rotating during drilling. At the same time, the electric push rod drives the rotary motor to move in opposite directions to clamp the shaft tube, ensuring the stability during drilling. When the position needs to be adjusted, the rotary motor will drive the shaft tube to rotate to adjust the drilling position. The support frame moves upward to support the bottom of the shaft tube, preventing excessive pressure from deforming the shaft tube and affecting the drilling effect. At the same time, when the drilling equipment moves to change the drilling position, the movement of the drilling equipment will drive the connecting rod to move. The movement of the connecting rod will push the slide plate to move. The movement of the slide plate will drive the support frame to move, so that the support frame is always under the drill bit, improving the overall support effect and improving the stability during drilling.

[0015] (2) In this invention, the cooling water and debris sprayed by the cooling device are collected by the upward movement of the rotating plate and the cooling plate flows into the base along the rotating plate. This prevents the debris from mixing with the cooling water and causing the machine casing to be filled with debris, which would affect the subsequent processing effect. At the same time, the upward movement of the sealing plate will release the seal on the air blowing port, allowing the air blower to blow out gas through the air blowing port to clean the debris that adheres to the shaft tube during drilling, preventing the debris from adhering to the shaft tube and affecting the drilling accuracy. After the processing is completed, the sealing plate will reset and seal the air blowing port to prevent moisture from entering the air blower and causing a short circuit in the air blower circuit system, which would affect the normal operation of the equipment.

[0016] (3) In this invention, the slag inside the sieve frame is leveled by moving the sieve frame up and down, which prevents the slag from accumulating too high and affecting the subsequent slag recycling. At the same time, when the sieve frame moves upward, it will drive the round rod to move upward. The round rod will be stuck inside the base. The upward movement of the round rod limits the sieve frame and prevents the operator from pulling out the sieve frame during the processing, which would cause the slag generated during the processing to fail to flow away through the filtration between the sieve frame, resulting in the drainage hole at the bottom of the base being blocked and affecting the drainage effect.

[0017] (4) In this invention, the upward movement of the screening frame will drive the sliding plate and the trapezoidal frame to move upward. The upward movement of the trapezoidal frame will contact the L-shaped plate, and the L-shaped plate will push the trapezoidal frame towards the middle of the screening frame. The pushing of the trapezoidal frame towards the middle of the screening frame will drive the sliding plate towards the middle of the screening frame. When the processing is completed and the screening frame is reset, the trapezoidal frame will lose its squeezing and drive the sliding plate to reset. The reset of the sliding plate will push the debris accumulated in the middle of the screening frame towards both sides of the screening frame, preventing the debris from accumulating in the middle of the screening frame and affecting the subsequent recycling of debris.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 - Figure 7 One embodiment of the present invention is: a drilling fixture for irregularly shaped motor shaft tubes based on CNC cutting tools, comprising: a base 1, a housing 2, the housing 2 being fixedly installed on the top of the base 1; a rotating door 3, the rotating door 3 being rotatably installed on the inner wall of the housing 2; a drilling device 4, the drilling device 4 being disposed on the top of the inner wall of the housing 2, a drainage hole being provided at the bottom of the base 1, and a cooling device being provided on the drilling device 4; an electric push rod 5, the electric push rod 5 being fixedly installed on the inner wall of the housing 2; a rotary motor 6 being fixedly installed on the output end of the electric push rod 5, the output end of the rotary motor 6 being provided with a slot for clamping and limiting the shaft tube; and the surface of the drilling device 4. A connecting rod 7 is fixedly installed. A slide rail 8 is fixedly installed on the inner wall of the housing 2. A slider 9 is slidably installed on the surface of the slide rail 8. A slide plate 10 is slidably installed on the surface of the slider 9. The end of the connecting rod 7 away from the drilling equipment 4 is slidably installed on the inner wall of the slide plate 10. A support frame 11 is set on the top of the slide plate 10. An L-shaped rod 12 is fixedly installed at the output end of the electric push rod 5. A U-shaped frame 13 is fixedly installed at the end of the L-shaped rod 12 away from the electric push rod 5. A trapezoidal pulley frame 14 is fixedly installed on the surface of the slide plate 10. The support frame 11 moves upward to support the bottom of the shaft tube, preventing excessive pressure from deforming the shaft tube and affecting the drilling effect.

[0022] A first spring is provided between the slider 9 and the slide plate 10. The slide plate 10 is reset by the elastic force of the first spring itself. The U-shaped frame 13 is located below the trapezoidal pulley frame 14.

[0023] In this embodiment, during operation: the shaft tube is placed in the slot, which limits its movement and prevents rotation during drilling. Simultaneously, the electric push rod 5 drives the rotary motor 6 to move in opposite directions, clamping the shaft tube and ensuring stability during drilling. When position adjustment is needed, the rotary motor 6 rotates the shaft tube to adjust the drilling position. The movement of the electric push rod 5 in opposite directions causes the L-shaped rod 12 to move in opposite directions, which in turn causes the U-shaped frame 13 to move in opposite directions. The movement of the U-shaped frame 13 pushes the trapezoidal pulley frame 14 upwards. Moving the 14 upwards will cause the slide plate 10 to move upwards, which in turn will cause the support frame 11 to move upwards. The upward movement of the support frame 11 will support the bottom of the shaft tube, preventing excessive pressure from deforming the shaft tube and affecting the drilling effect. At the same time, when the drilling equipment 4 moves to change the drilling position, the movement of the drilling equipment 4 will cause the connecting rod 7 to move, which will push the slide plate 10 to move. The movement of the slide plate 10 will cause the support frame 11 to move, keeping the support frame 11 always under the drill bit, improving the overall support effect and increasing the stability during drilling.

[0024] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, the chassis 2 is provided with a flow guiding device and a separation device. The flow guiding device includes a long plate 151, a sliding connecting plate 152, a connecting rope 153, and a rotating plate 154. The long plate 151 is fixedly installed on the surface of the trapezoidal pulley frame 14. The sliding connecting plate 152 is slidably installed on the inner wall of the chassis 2 and is slidably connected to the long plate 151. The connecting rope 153 is fixedly installed at the bottom of the sliding connecting plate 152. The rotating plate 154 is rotatably installed on the inner wall of the chassis 2. One end of the connecting rope 153 away from the sliding connecting plate 152 is fixedly installed on the top of the rotating plate 154. The rotating plate 154 moves upward so that the cooling water sprayed by the cooling device and the debris flow into the base 1 along the rotating plate 154, collecting the cooling water and debris, and preventing the debris from mixing with the cooling water, which would cause the inside of the chassis 2 to be full of debris and affect the subsequent processing effect.

[0025] A connecting frame 155 is fixedly installed on the top of the sliding connecting plate 152. An air blower 156 is provided on the inner wall of the housing 2. An air blowing port is opened on the surface of the air blower 156. A sealing plate 157 is slidably installed on the surface of the air blowing port, so that the air blower 156 blows out air through the air blowing port to clean the debris that adheres to the shaft tube during drilling, preventing debris from adhering to the shaft tube and affecting the accuracy of drilling.

[0026] A second spring is installed between the sliding connecting plate 152 and the chassis 2. The second spring's own elastic force drives the sliding connecting plate 152 to reset. A first torsion spring is installed between the rotating plate 154 and the chassis 2. The first torsion spring's own elastic force drives the rotating plate 154 to reset. A third spring is installed between the air outlet and the sealing plate 157. The third spring's own elastic force drives the sealing plate 157 to reset.

[0027] In this embodiment, during operation: the trapezoidal pulley frame 14 moves upward, causing the long plate 151 to move upward. The upward movement of the long plate 151 causes the sliding connecting plate 152 to move upward. The upward movement of the sliding connecting plate 152 pulls the connecting rope 153 upward, which in turn pulls the rotating plate 154 upward. The upward movement of the rotating plate 154 causes the cooling water and debris sprayed from the cooling device to flow into the base 1, collecting the cooling water and debris. This prevents the debris from mixing with the cooling water, which would cause the inside of the machine casing 2 to accumulate debris and affect subsequent processing results. Simultaneously, the upward movement of the sliding connecting plate 152 will drive the connecting frame 155 to move upward. The upward movement of the connecting frame 155 will push the sealing plate 157 to move upward. The upward movement of the sealing plate 157 will disengage from the air blowing port, allowing the air blower 156 to blow out gas through the air blowing port to clean the debris that adhered to the shaft tube during drilling, preventing debris from adhering to the shaft tube and affecting the accuracy of drilling. At the same time, after the processing is completed, the sealing plate 157 will reset and seal the air blowing port to prevent moisture from entering the air blower 156, causing a short circuit in the air blower 156's circuit system and affecting the normal operation of the equipment.

[0028] The separation device includes a pulley frame 161, a long slide plate 162, a screen frame 163, and a round rod 164. The pulley frame 161 is slidably installed on the inner wall of the base 1, the long slide plate 162 is slidably installed on the inner wall of the base 1, the screen frame 163 is slidably installed on the surface of the long slide plate 162, and the round rod 164 is fixedly installed on the top of the screen frame 163. The screen frame 163 moves up and down to level the debris inside the screen frame 163, preventing the debris from accumulating too high and affecting subsequent debris recycling. At the same time, when the screen frame 163 moves upward, it will drive the round rod 164 to move upward. The upward movement of the round rod 164 will lock into the interior of the base 1, limiting the screen frame 163 and preventing the operator from pulling out the screen frame 163 during processing. This would prevent the debris generated during processing from flowing away through the filter of the screen frame 163, causing the drainage hole at the bottom of the base 1 to become blocked.

[0029] An L-shaped plate 165 is fixedly installed on the inner wall of the base 1, and a sliding plate 166 is slidably installed on the inner wall of the screening frame 163. A trapezoidal frame 167 is fixedly installed on the surface of the sliding plate 166. When the sliding plate 166 is reset, the slag accumulated in the middle of the screening frame 163 will be pushed to both sides of the screening frame 163 to prevent the slag from accumulating in the middle of the screening frame 163 and affecting the subsequent recycling of slag.

[0030] A No. 4 spring is installed between the pulley frame 161 and the base 1. The pulley frame 161 is reset by the elastic force of the No. 4 spring. A No. 5 spring is installed between the long slide plate 162 and the base 1. The long slide plate 162 is reset by the elastic force of the No. 5 spring. A No. 6 spring is installed between the screen frame 163 and the sliding plate 166. The sliding plate 166 is reset by the elastic force of the No. 6 spring.

[0031] The rotating plate 154 rotates upward to release the pressure on the pulley frame 161. The elastic force of the fourth spring causes the pulley frame 161 to move upward, releasing the pressure on the screen frame 163. The elastic force of the fifth spring causes the long sliding plate 162 and the screen frame 163 to move upward. The up-and-down movement of the screen frame 163 flattens the debris inside, preventing excessive accumulation and hindering subsequent debris recycling. Simultaneously, the upward movement of the screen frame 163 causes the round rod 164 to move upward, locking into the base 1. The upward movement of the round rod 164 limits the movement of the screen frame 163, preventing operators from pulling it out during processing and ensuring that debris generated during processing passes through the screen. The material flows out between the filters in frame 163, causing the drain hole at the bottom of base 1 to become clogged, affecting the drainage effect. At the same time, when the screen frame 163 moves upward, it will drive the sliding plate 166 and the trapezoidal frame 167 to move upward. When the trapezoidal frame 167 moves upward, it will contact the L-shaped plate 165. The L-shaped plate 165 will push the trapezoidal frame 167 towards the middle of the screen frame 163. The pushing of the trapezoidal frame 167 towards the middle of the screen frame 163 will drive the sliding plate 166 towards the middle of the screen frame 163. When the processing is completed and the screen frame 163 is reset, the trapezoidal frame 167 will lose its compression and drive the sliding plate 166 to reset. The reset of the sliding plate 166 will push the debris accumulated in the middle of the screen frame 163 to both sides of the screen frame 163, preventing the debris from accumulating in the middle of the screen frame 163 and affecting the subsequent recycling of debris.
