Description

Technical Field

[0001] This invention relates to the field of shaft cutting technology, specifically a cutting device for processing shaft parts for new energy vehicles. Background Technology

[0002] In the actual processing of shaft parts for new energy vehicles, such as motor shafts, the blanks need to be cut into sections before precision machining. Because the precision requirements are not high, for the sake of efficiency and cost considerations, alloy saw blades are usually used for cutting. The cutting is done by alloy cutting heads on the saw teeth of the saw blade. However, the current cutting devices for processing shaft parts for new energy vehicles are not convenient for automatic control and clamping protection. The safety of clamping the shaft blanks is not good. After long-term use, the saw blade is prone to excessive wear due to high temperature and other factors, resulting in tooth breakage and deformation. After the saw teeth are cut at high temperatures, it is not convenient for manual inspection of missing teeth. The safety of the saw blade is reduced after missing teeth. At the same time, it is not convenient to adapt the support for the section cutting of long shaft blanks.

[0019] 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.

[0020] Example 1: Please refer to Figures 1 to 11 As shown: This invention provides a technical solution: a cutting device for processing shaft parts of new energy vehicles, including a cutting mounting component 1, a clamping detection component 2 mounted on the cutting mounting component 1 for clamping and protection; a cutting part 3 mounted on the bottom of the cutting mounting component 1; a shaft end support component 4 mounted on the cutting mounting component 1 for supporting the shaft end of the blank to be cut; a tooth defect detection component 5 mounted on the cutting mounting component 1; a detection device 6 mounted on the tooth defect detection component 5; the cutting mounting component 1 includes: a cutting mounting plate 101 and a fixing clamp 102, two fixing clamps 102 are fixedly mounted on the cutting mounting plate 101 by bolts; a bracket is fixedly mounted on the bottom of the cutting mounting plate 101.

[0021] The cutting mounting component 1 further includes: an indicator light 1011, a movable clamping block 103, and a clamping hydraulic cylinder 104. Two movable clamping blocks 103 are slidably mounted on the cutting mounting plate 101. Two clamping hydraulic cylinders 104 are fixedly mounted on the cutting mounting plate 101, and the output shafts of the two clamping hydraulic cylinders 104 are respectively fixedly mounted on the two movable clamping blocks 103. V-grooves are provided on the inner sides of the two fixed clamping blocks 102 and the movable clamping blocks 103. An indicator light 1011 is fixedly mounted on the cutting mounting plate 101. The clamping detection component 2 includes: a sliding mounting block 201, a detection shaft 2011, and a clamping switch 202. A sliding mounting block 201 is fixedly mounted on the side of the right movable clamping block 103. A detection shaft 2011 is slidably inserted into the mounting block 201; the end of the detection shaft 2011 is pressed against the workpiece to be cut; a tension spring is sleeved on the detection shaft 2011, and the tension spring sleeved on the detection shaft 2011 is connected between the sliding mounting block 201 and the detection shaft 2011; a clamping switch 202 is fixedly installed on the side of the right movable clamping block 103, and the detection shaft 2011 is aligned with the clamping switch 202; the cutting part 3 includes: a cutting mounting frame 301, a drive motor 3011, a cutting hydraulic cylinder 302, and a cutting alloy saw blade 303; the cutting mounting frame 301 is slidably installed on the bottom of the cutting mounting plate 101; the drive motor 3011 is fixedly installed inside the cutting mounting frame 301; the output of the drive motor 3011... The shaft passes through the cutting mounting frame 301; a cutting alloy saw blade 303 is fixedly mounted on the output shaft of the drive motor 3011, and the cutting alloy saw blade 303 passes through the cutting mounting plate 101; a cutting hydraulic cylinder 302 is fixedly sleeved at the bottom of the cutting mounting frame 301, and the output shaft of the cutting hydraulic cylinder 302 is fixedly mounted at the bottom of the cutting mounting plate 101. The cutting part 3 can realize rapid movement to cut the shaft blank, and at the same time, it works with the cutting mounting part 1 to stably clamp the shaft blank, keeping the cutting stable. At the same time, the clamping detection part 2 can automatically perform clamping detection work, which can effectively avoid the cutting alloy saw blade from being used when disassembling or installing the shaft blank after the actual cutting work is completed or before the cutting work is started. The 303 blade continues to rotate, causing splashing and friction during clamping or disassembling of the shaft blank, which could pose a safety hazard. To ensure effective clamping of the shaft blank before actual cutting, the structure is more reasonable and safer to use, reducing the safety hazards caused by the high-speed rotating cutting alloy saw blade 303. As the shaft blank is clamped, the detection shaft 2011 is also squeezed and moved backward by the shaft blank, stretching the tension spring on the outside of the detection shaft 2011. The detection shaft 2011 also moves backward, squeezing the clamping switch 202, controlling the drive motor 3011 to be powered on normally for cutting drive. When the clamping switch 202 is not pressed, it will immediately control the drive motor 3011 to be powered off, avoiding safety hazards caused by manual handling and adjustment of the shaft blank.

[0022] The shaft end support 4 includes a support slide rod 401 and a collar 402. The support slide rod 401 is slidably mounted on the cutting mounting plate 101. The collar 402 is fixedly mounted on the support slide rod 401 and is used to receive the cutting blank. The shaft end support 4 also includes a positioning bolt 403, which is threaded onto the collar 402, with the end of the positioning bolt 403 passing through the collar 402. The shaft end support 4 also includes a positioning switch 404, which is fixedly embedded at the end of the positioning bolt 403. The end of the switch 404 has a protruding positioning bolt 403; the positioning switch 404 is electrically connected to the indicator light 1011, and the positioning switch 404 is electrically connected to the warning light 1011 (not shown); the use of the shaft end support 4 can facilitate the support of the tail end when clamping and cutting long shaft blanks, which can effectively prevent the tail end from bending downward under its own weight, affecting the straightness of the shaft blank and ensuring cutting accuracy. At the same time, the positioning switch 404 in this structure can automatically detect the position of the shaft blank and can indicate that the tail end of the shaft blank is supported and clamped.

[0023] In Example 2, based on Example 1, the missing tooth detection component 5 includes: a detection mounting frame 501, a detection electric push rod 502, and a start / stop switch 503. The detection mounting frame 501 has sliding protrusions on both sides. The detection mounting frame 501 is slidably mounted on the cutting mounting plate 101. The detection electric push rod 502 is fixedly mounted on the bottom of the cutting mounting plate 101. The output shaft of the detection electric push rod 502 is fixedly mounted on the detection mounting frame 501. The start / stop switch 503 is fixedly mounted on the back of the detection mounting frame 501. The three ends are pressed and attached to the inside of the cutting mounting plate 101; the start / stop switch 503 and the clamping switch 202 are electrically connected to the drive motor 3011; the start / stop switch 503 and the clamping switch 202 are electrically connected to the drive motor 3011 (not shown); the missing tooth detection component 5 also includes: a grounding block 504, a series grounding strip 505 and a missing tooth indicator light 506, the detection mounting frame 501 is provided with a ring of through holes, and the through holes on the detection mounting frame 501 are aligned with the saw teeth on the cutting alloy saw blade 303; the through holes on the detection mounting frame 501 are respectively fixed in... Two electrical contact blocks 504 are installed; a series of electrical contact strips 505 are fixedly installed on the detection mounting frame 501, and the series of electrical contact strips 505 are staggered and attached to the electrical contact blocks 504 respectively; the series of electrical contact strips 505 are connected in series with the electrical contact blocks 504; the first and last two electrical contact blocks 504 and the missing tooth indicator light 506 are connected in series with the battery power supply; the missing tooth indicator light 506 is fixedly installed on the cutting mounting plate 101; the electrical contact blocks 504 and the detection mounting frame 501 are insulated; the detection device 6 includes: a detection shaft 601, a fixing ring 602, and a conductive... The test shaft 601 is slidably inserted into a ring of through holes on the test mounting bracket 501, and the test shaft 601 is made of ceramic insulating material; the end of the test shaft 601 has a tapered structure; a fixing ring 602 is fixedly installed in a ring of through holes on the test mounting bracket 501; the test shaft 601 is slidably inserted into the fixing ring 602; a conductive iron piece 603 is provided at the tail of the test shaft 601; the conductive iron piece at the tail of the test shaft 601 is used to attach to the corresponding contact block 504;A spring 604 is sleeved on the detection shaft 601, and the spring on the detection shaft 601 is connected between the detection shaft 601 and the fixing ring 602. The use of the missing tooth detection component 5 in conjunction with the detection device 6 allows workers to easily inspect the missing tooth deformation of the cutting alloy saw blade 303. This effectively prevents the continued use of the cutting alloy saw blade 303 with missing teeth or excessive deformation, thus avoiding safety hazards. This structure provides accurate and direct detection, and can cover all the saw teeth on the cutting alloy saw blade 303. It eliminates the need for manual rotation and adjustment of the cutting alloy saw blade 303, making it more efficient and effectively ensuring the safety of the cutting operation. Furthermore, the use of the start / stop switch 503 further ensures the safety of the detection process. The system can automatically stop the drive motor 3011 when detecting the cutting alloy saw blade 303, ensuring safety during the detection process and preventing the saw teeth from colliding with the detection shaft 601. When the end of the detection shaft 601 is pressed against the cutting alloy saw blade 303, regardless of whether the end of the detection shaft 601 is against the end of the saw teeth or between the teeth, the spacing between the teeth is the same. This compression of the spring on the outside of the detection shaft 601 causes the conductive iron piece at the tail of the detection shaft 601 to adhere to the rear contact block 504. At this point, all contact blocks 504 become conductive, illuminating the missing tooth indicator light 506.

[0024] The working principle of this embodiment is as follows: First, when cutting the shaft blank, the shaft blank passes through the collar 402 during clamping. The positioning bolt 403 drives the positioning switch 404 to squeeze the shaft blank. At this time, the indicator light 1011 lights up normally to indicate that everything is normal. With the help of the sliding support rod 401, the shaft blank can be moved and adjusted to the cutting position. The shaft blank needs to be placed in the V-groove of the fixed clamping block 102. At this time, the clamping hydraulic cylinder 104 drives the moving clamping block 103 to move and clamp the shaft blank. As the shaft blank is clamped, the detection shaft 2011 is also squeezed and moved backward by the shaft blank, stretching the outer side of the detection shaft 2011. When the spring moves the detection shaft 2011 backward, it will press the clamping switch 202, which will control the drive motor 3011 to be powered on normally for cutting. The cutting hydraulic cylinder 302 will drive the cutting mounting frame 301 to move the drive motor 3011 forward to cut the shaft blank. At the same time, after the shaft blank is cut into a segment, it is necessary to release the clamp and re-measure the distance before clamping. Once the clamping hydraulic cylinder 104 drives the moving clamping block 103 to move backward, the detection shaft 2011 will no longer be pressed by the shaft blank. At this time, when the clamping switch 202 is not pressed, it will immediately control the drive motor 3011 to be powered off to avoid safety hazards when manually handling and adjusting the shaft blank.After segmented cutting, the control cutting hydraulic cylinder 302 drives the cutting mounting frame 301 to retract to the initial position, and then the control detection electric push rod 502 drives the detection mounting bracket 501 to move forward, causing the detection shaft 601 to press against the cutting alloy saw blade 303. At this time, the start / stop switch 503 is also driven forward and no longer presses against the cutting mounting plate 101. At this time, the drive motor 3011 can stop rotating for protection. When the end of the detection shaft 601 presses against the cutting alloy saw blade 303, whether the end of the detection shaft 601 is against the end of the saw teeth or the interval between the saw teeth of the cutting alloy saw blade 303, the entire detection shaft 601 will be compressed, compressing the spring on the outside of the detection shaft 601. The conductive iron piece at the tail of the detection shaft 601 can then be attached to the rear contact block 504. At this time, each contact... When the electrical block 504 is turned on, the missing tooth indicator light 506 will illuminate. Conversely, if there is a partial missing tooth, there is no saw tooth stop, and the corresponding detection shaft 601 cannot retract to engage with the electrical block 504. In this case, the series-connected electrical blocks 504 cannot conduct, and the missing tooth indicator light 506 will not illuminate. Similarly, if the saw teeth on the cutting alloy saw blade 303 are misaligned or deformed beyond the standard, the uneven saw blade will also be unable to simultaneously compress the detection shaft 601 to move backward and conduct. The structural detection is simple and direct. After detection, the control detection electric push rod 502 drives the detection mounting bracket 501 to retract, which in turn drives the start / stop switch 503 to compress the cutting mounting plate 101, thus controlling the drive motor 3011 to reconnect to power and resume normal cutting without interference from the detection shaft 601.
