Description

Technical Field

[0001] This invention relates to the field of grooved shaft testing technology, specifically a performance testing device for grooved shaft machining. Background Technology

[0002] The grooved yarn bobbin is a key component in textile machinery, widely used in equipment such as chemical fiber texturing machines, winding machines, and doubling machines. It affects the forming and unwinding performance of the yarn package. The grooved yarn bobbin is driven to rotate by a motor or other drive device. The yarn guide, installed within the spiral groove of the bobbin, reciprocates laterally with the rotation of the bobbin. The yarn guide drives the yarn in this reciprocating motion, allowing the yarn to move back and forth during winding, thus forming a shaped yarn package.

[0003] Grooved shafts are core transmission components in textile and other equipment, and their compressive strength directly determines the stability and reliability of the equipment's operation. Therefore, compressive strength testing is required after processing. Currently, radial pressure is often applied to the grooved shaft using hydraulic rods or servo motors, and pressure and displacement sensors are used to collect pressure data and deformation in real time. This is used to verify the mechanical properties and structural stability of the grooved shaft under simulated actual working loads.

[0004] To make the test scenario more closely resemble the actual working state of the grooved shaft winding yarn at high speed, existing technologies often use radial pressure to apply radial pressure to the grooved shaft under rotating conditions for compression testing. At the same time, grease is applied to the contact area between the pressure head and the shaft body. Applying grease can effectively reduce friction and wear between the two, avoid local overheating, and ensure the stability of load transmission. However, after the compression test, the grease remaining on the surface of the grooved shaft under pressure needs to be cleaned manually, which is a cumbersome operation. Summary of the Invention

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Please see Figures 1-9A performance testing device for machining grooved shafts includes a test bench 101, on which two symmetrically distributed fixed seats 102 are mounted. A fixed cylinder 103 is rotatably mounted on each fixed seat 102. A test base 401 is mounted in the middle of the test bench 101, and a top frame 402 is mounted on the test base 401. A telescopic member 403 is mounted on the top frame 402. Preferably, the telescopic member 403 is a hydraulic rod. A lifting frame 404 is mounted on the telescopic end of the telescopic member 403. A pressure head 405 is mounted on the bottom of the lifting frame 404. Two symmetrically distributed pressure rollers 406 are rotatably arranged on the bottom of the pressure head 405. The device also includes: A cleaning component 5, located on the test seat 401, is used to clean the residual grease in the pressure area of ​​the groove shaft. The cleaning component 5 includes a cleaning frame 501, a storage cavity 502, a first rotating shaft 503 and a second rotating shaft 505 rotatably arranged in the storage cavity 502, a winding roller 504 mounted on the first rotating shaft 503, and an unwinding roller 506 mounted on the second rotating shaft 505. A cleaning belt 509 is provided on the winding roller 504 and the unwinding roller 506. A first guide wheel 507 and a second guide wheel 508 are rotatably arranged on the top of the cleaning frame 501, which are in contact with the cleaning belt 509. The cleaning belt 509 between the first guide wheel 507 and the second guide wheel 508 is inclined. A damping ring 510 is installed in the storage cavity 502, which is in contact with the outer wall of the first rotating shaft 503 and the second rotating shaft 505. Limiting component 6 is disposed on test seat 401 and is used to limit the initial position of cleaning component 5; Elastic component 8 is disposed between the limiting component 6 and the cleaning rack 501 to achieve an elastic connection between the cleaning rack 501 and the limiting component 6. The material displacement component 9 is disposed between the limiting component 6 and the cleaning frame 501. During the process of cleaning the grease on the surface of the cleaning belt 509 cleaning the groove cylinder shaft, the cleaning belt 509 is displaced and conveyed. The drive assembly 7 is disposed between the lifting frame 404 and the limiting assembly 6. During the process of the pressure head 405 rising, the drive assembly 7 drives the limiting assembly 6, so that the cleaning belt 509 on the cleaning frame 501 moves to contact the groove shaft and begins to clean the grease on the groove shaft. After the cleaning frame 501 moves into place, it begins to drive the cleaning belt 509 to change position and replace it.

[0026] In one instance of this embodiment, please refer to Figure 2 and Figure 3The limiting component 6 includes two limiting blocks 603, which are distributed on both sides of the cleaning rack 501. The limiting blocks 603 are slidably connected to the limiting rod 602. The two ends of the limiting rod 602 are equipped with support plates 601 connected to the test seat 401. A first elastic element 604 connected to the limiting block 603 is provided on the support plate 601 near the middle of the test seat 401. Preferably, the first elastic element 604 is a spring.

[0027] Due to the elastic force applied by the first elastic member 604 to the limiting block 603, in the initial state, the limiting block 603 is located at the support plate 601 at one end away from the middle of the test seat 401. At this time, there is a certain distance between the cleaning belt 509 on the cleaning rack 501 connected to the limiting block 603 by the elastic component 8 and the fixed groove shaft, thereby restricting the cleaning rack 501 to the initial position.

[0028] In one instance of this embodiment, please refer to Figure 3 and Figure 4 The elastic component 8 includes elastic grooves 801 formed on both sides of the cleaning rack 501. An elastic block 802 connected to the limiting block 603 is slidably disposed in the elastic groove 801. A second elastic element 803 connected to the elastic block 802 is disposed at one end of the elastic groove 801 near the middle of the test seat 401. Preferably, the second elastic element 803 is a spring. A positioning block 804 is installed in the middle of the test seat 401.

[0029] As the drive assembly 7 drives the limiting block 603 to move along the limiting rod 602, the limiting block 603 also drives the elastic block 802 in the elastic groove 801 to move synchronously. The elastic block 802 can push the cleaning frame 501 through the second elastic element 803, so that the cleaning frame 501 moves toward the groove shaft until the cleaning belt 509 on the cleaning frame 501 contacts the outer wall of the groove shaft. At this time, the front end of the cleaning frame 501 contacts the positioning block 804, thereby limiting the cleaning frame 501. Thus, during the subsequent movement of the limiting block 603, the material displacement assembly 9 can continue to be driven, while the position of the cleaning frame 501 remains unchanged.

[0030] Furthermore, the drive assembly 7 includes a limiting frame 705 installed on both sides of the side wall of the top frame 402. A lifting rod 704 connected to the lifting frame 404 is slidably arranged on the limiting frame 705. An inclined rod 703 is installed at the bottom of the lifting rod 704. The limiting block 603 is provided with an inclined groove 701 and a slot 702 that cooperate with the inclined rod 703. The top of the inclined rod 703 is an inclined surface that cooperates with the inclined groove 701.

[0031] After the pressure test on the grooved shaft is completed, the telescopic component 403 will drive the lifting frame 404 to rise, thereby driving the pressure head 405 to rise synchronously and separate from the grooved shaft. At the same time, the grooved shaft begins to rotate at low speed to enter the grease cleaning step.

[0032] When the lifting frame 404 rises to a certain height, the inclined rod 703 at the bottom of the lifting rod 704 begins to contact the limiting block 603, and the inclined surface at the top of the inclined rod 703 begins to contact the inclined groove 701 of the limiting block 603. As the inclined rod 703 rises, it can push the limiting block 603 to slide along the limiting rod 602. Through the elastic component 8 connected to the limiting rod 602, the cleaning frame 501 can be pushed towards the center of the test seat 401, so that the cleaning belt 509 on the cleaning frame 501 contacts the outer wall of the groove shaft, thereby cleaning the residual heat in the pressure area on the rotating groove shaft. After the grease is cleaned, the inclined rod 703 continues to push the limiting block 603 until it enters the slot 702. During this process, the material displacement component 9 is driven. After the grease on the groove shaft is cleaned, the telescopic component 403 drives the lifting frame 404 to descend a certain distance. Under the elastic force of the elastic component 8, the inclined rod 703 is disengaged from the slot 702, and the elastic component 8 is reset. As the lifting frame 404 continues to descend, and with the help of the elastic force of the limiting component 6, the inclined rod 703 can be separated from the inclined groove 701, and the limiting component 6 is reset, thereby completing the reset of the drive component 7.

[0033] In one instance of this embodiment, please refer to Figure 2 , Figures 5-7 The material displacement assembly 9 includes a displacement frame 902 mounted on a limiting block 603. A plurality of spaced mounting seats 903 are mounted on the bottom of the displacement frame 902. A movable shaft 904 is rotatably mounted on the mounting seat 903. A displacement plate 905 is mounted on the movable shaft 904. A third gear part 901 that cooperates with the displacement plate 905 is mounted on one end of the first rotating shaft 503 outside the cleaning frame 501. A third elastic element 907 connected to the displacement frame 902 is provided on the side of the displacement plate 905 away from the limiting block 603. Preferably, the third elastic element 907 is a spring. A baffle 906 is provided on the side of the mounting seat 903 near the limiting block 603.

[0034] The damping ring 510 creates rotational resistance between the first shaft 503 and the second shaft 505 during rotation, which facilitates the material shifting assembly 9 to drive the winding roller 504 on the first shaft 503 to wind the cleaning belt 509, while the unwinding roller 506 on the second shaft 505 releases the cleaning belt 509 and keeps the cleaning belt 509 between the winding roller 504 and the unwinding roller 506 in a straight state.

[0035] When the cleaning frame 501 moves to the position of the positioning block 804, the cleaning belt 509 contacts the outer wall of the groove shaft, thereby cleaning the grease in the pressure area of ​​the groove shaft. As the drive assembly 7 continues to drive the limiting block 603 to move, the cleaning frame 501 is limited by the positioning block 804. During this movement, the limiting block 603 compresses the second elastic element 803 through the elastic block 802, driving the displacement frame 902 to move relative to the cleaning frame 501. Because the baffle 906 limits the position plate 905, the position plate 905 can drive the third gear 901 to rotate, thereby driving the first rotating shaft 503 to rotate, causing the winding roller 504 to start winding the cleaning belt 509, and the unwinding roller 506 on the second rotating shaft 505 to start unwinding the clean cleaning belt 509, thereby realizing the displacement and conveying of the cleaning belt 509, so that the grooved shaft can always be in contact with the clean cleaning belt 509, thereby achieving effective cleaning of the grease on the grooved shaft.

[0036] The position plate 905 drives the third gear section 901 to rotate only when the limit block 603 moves toward the middle of the test table 101. When resetting, the position plate 905 can pass over the teeth of the third gear section 901 in one direction.

[0037] During the reset of the drive assembly 7, the limit assembly 6 and the elastic assembly 8 will also reset synchronously. During the reset of the elastic assembly 8, the positioner 902 will also move. During this process, due to the damping limit of the first rotating shaft 503 by the damping ring 510 and the cooperation of the third elastic member 907, when the positioner 905 contacts the tooth block of the third gear part 901, the third gear part 901 remains fixed, while the positioner 905 rotates, so that several positioners 905 can pass over the tooth block of the third gear part 901 in sequence until the positioner 902 completes the reset.

[0038] The moving direction of the cleaning belt 509 is opposite to the rotation direction of the groove shaft. Therefore, during the contact between the groove shaft and the cleaning belt 509, the positioning plate 905 limits the third gear part 901, so that the cleaning belt 509 will not be displaced due to friction.

[0039] In one instance of this embodiment, please refer to Figure 1 and Figure 9The fixed cylinder 103 is provided with a fixing component 2, including a plurality of annularly distributed sliding grooves 201 opened in the fixed cylinder 103. A sliding rod 202 is slidably arranged in the sliding grooves 201. A fixing plate 203 is installed at one end of the sliding rod 202 located in the fixed cylinder 103. A locking disc 204 is rotatably arranged on the fixed cylinder 103. A plurality of guide grooves 205 corresponding to the sliding grooves 201 are opened on the locking disc 204. A guide rod 206 connected to the sliding rod 202 is slidably arranged in the guide grooves 205. A first driving member 209 is installed on the fixed cylinder 103. Preferably, the first driving member 209 is a motor. A first gear part 208 is installed at the driving end of the first driving member 209, and a first gear groove 207 that cooperates with the first gear part 208 is opened on the outer wall of the locking disc 204.

[0040] After the grooved shaft passes through the two fixed cylinders 103, the first driving member 209 is activated. The first driving member 209 drives the locking disc 204 to rotate through the first gear part 208 and the first gear groove 207. The guide rod 206 is displaced by the guide groove 205 on the locking disc 204, thereby pushing the slide rod 202 to move along the slide groove 201 towards the middle of the fixed cylinder 103 until several fixed plates 203 complete the centering clamping of the grooved shaft. The fixed plates 203 are arc-shaped plates that cooperate with the outer wall of the grooved shaft.

[0041] In one instance of this embodiment, please refer to Figure 1 and Figure 9 The test bench 101 is provided with a rotating assembly 3, including a second driving component 303 installed on the test bench 101. Preferably, the second driving component 303 is a motor. The driving end of the second driving component 303 is equipped with a second gear part 302. The outer wall of the fixed cylinder 103 is provided with a second gear groove 301 that cooperates with the second gear part 302.

[0042] When simulating the rotation and pressure of the grooved shaft, the second drive unit 303 is activated, and the fixed cylinder 103 is driven to rotate through the second gear part 302 and the second gear groove 301, thereby driving the grooved shaft fixed by the fixed assembly 2 to rotate.

[0043] This invention involves passing the grooved shaft through two fixed cylinders 103 and fixing both ends of the grooved shaft using a fixing assembly 2. Lubricant is then applied to the pressure rollers 406 of the pressure head 405 to reduce friction and wear in the contact area between the pressure rollers 406 and the grooved shaft, ensuring the stability of load transmission by the pressure head 405. The lifting frame 404 is then driven to descend via a telescopic component 403, which in turn drives the pressure head 405 to descend, causing the pressure rollers 406 at the bottom of the pressure head 405 to press against the outer wall surface of the grooved shaft. The telescopic component 403 allows the pressure head 405 to apply a downward radial force to the grooved shaft. The rotating assembly 3 then drives the fixed cylinders 103 to rotate, thereby rotating the grooved shaft. This allows for the testing of the grooved shaft's compressive strength under rotational conditions. The pressure head 405 incorporates a pressure sensor for real-time pressure monitoring, and auxiliary analyzers and measuring instruments are used to analyze the data from the grooved shaft.

[0044] After the grooved shaft completes the test, the rotating component 3 drives the grooved shaft to start rotating at a low speed, and the telescopic component 403 starts driving the lifting frame 404 to rise, causing the pressure roller 406 to separate from the grooved shaft. When the lifting frame 404 rises to a certain height, the driving component 7 is triggered. At this time, the limiting component 6 starts pushing the cleaning belt 509 on the cleaning frame 501 towards the grooved shaft through the elastic component 8 until the cleaning belt 509 contacts the outer wall of the grooved shaft, thereby cleaning the residual grease on the outer wall of the rotating grooved shaft. At this time, the cleaning frame 501 stops moving. Due to the presence of the elastic component 8, the limiting component 6 can continue to move, allowing the material displacement component 9 to drive the cleaning belt 509 to continuously move and thus keep the grooved shaft in contact with the outer wall of the grooved shaft. The clean cleaning belt 509 contacts the grooved shaft, effectively cleaning residual grease during the rotation of the grooved shaft. After cleaning, the telescopic component 403 drives the lifting frame 404 to descend a certain distance, causing the cleaning frame 501 to reset and await the next cleaning operation. After the grooved shaft completes the pressure test, during the separation and ascent of the pressure head 405 from the grooved shaft, the cleaning belt 509 contacts the outer wall of the grooved shaft, thereby cleaning the grease on the outer wall of the grooved shaft. During the cleaning process, the material displacement component 9 can displace and convey the cleaning belt 509, so that the grooved shaft can be continuously cleaned through the clean cleaning belt 509, thereby achieving automatic cleaning of the grease on the grooved shaft and reducing the cleaning burden on workers.
