Description

Technical Field

[0001] The invention relates to the technical field of strength testing equipment, in particular to a carbon fiber badminton shaft strength testing device. Background Art

[0002] In the manufacturing process of carbon fiber badminton shafts, strength testing is a key link to ensure product quality and performance. At present, the strength testing method commonly used in the industry is to batch-cut multiple sets of badminton racket shafts from the production batch as test samples, and the staff manually place each shaft on the testing equipment one by one. During the test, the downward pressure head of the testing equipment descends to apply pressure to the shaft, and the relevant data is collected and recorded by the sensor to evaluate the strength performance of the badminton shaft.

[0003] However, this traditional manual batch testing method has significant drawbacks. On the one hand, since the entire testing process relies on manual operation, workers need to repeatedly take and place the middle poles, resulting in low testing efficiency and difficulty in meeting the rapid testing needs of large-scale production. On the other hand, in the process of manually placing the middle poles, different workers have different operating habits and strength. Even if the same worker operates, it is difficult to ensure that the placement of each set of middle poles on the testing equipment is completely consistent. Slight deviations in the placement of the middle poles will cause changes in the point of force and direction of pressure applied by the downward pressure head, thereby affecting the accuracy of the data collected by the sensor, and ultimately reducing the overall testing accuracy, making it impossible for the test results to truly and reliably reflect the actual strength performance of the carbon fiber badminton poles. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a carbon fiber badminton shaft strength testing device to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a carbon fiber badminton shaft strength testing device, comprising a main body, a strength detection mechanism installed at the top end of the main body, and rotation support mechanisms installed at both sides of the bottom end of the main body; The rotation support mechanism consists of a set of rotating columns and support arms fixed at the four outer corners thereof. A placement rod is fixed at the end of each set of support arms, and the placement rod plays a bearing role in the centering rod. The strength detection mechanism includes an electric push rod installed on the main body, and a pressure sensor and a pressing head are connected in sequence below the output end of the electric push rod, wherein the pressing head plays the role of applying pressure to the centering rod; The rotation support mechanism also includes a support plate and an anti-compression rod. The rotating shaft passes through the support plate and is rotatably connected thereto. The support plate plays a role in supporting the movable support of the rotation support mechanism. Anti-compression rods are fixed between the four groups of support arms. The anti-compression rods play a role in strengthening the strength of the four groups of support arms. The rotation support mechanism also includes a positioning ring and an rubber ring. Two groups of positioning rings are fixed to the outside of each group of placement rods. The two groups of positioning rings play a role in positioning and stabilizing the centering rod after placement, and the rubber ring is fixed at the middle position of the outside of the placement rod to play a role in stabilizing the placement of the centering rod. Connecting rods are fixed on both sides of the output end of the electric push rod, and a fixed frame is fixed at the bottom of the two sets of connecting rods, and multiple sets of material shifting clamps are evenly fixed at the bottom of the fixed frame. The material shifting clamps are composed of two sets of plates, one set of which is vertical, and the other set of plates is composed of a vertical part, an inclined part and a vertical part from bottom to top. The material shifting clamps are lowered to play the role of shifting the material of the centering rod; The strength detection mechanism also includes a transmission rod and a tooth plate. One end of the transmission rod is fixedly connected to the connecting rod, and the other end is fixedly connected to the tooth plate, which is used to drive the tooth plate to rise and fall. The rotation support mechanism also includes a rotating shaft, a gear and a one-way bearing. The gear and the rotating shaft are movably connected through the one-way bearing, and the outer side of the gear is engaged with the tooth plate. When the tooth plate rises and engages with the gear, the rotating column rotates, which plays a role in adjusting the angle of the rotating column. A discharge mechanism is installed at one end of the main body, and the material trough opened inside the discharge box of the discharge mechanism plays the role of arranging multiple groups of middle rods in sequence, and the overall tilt design of the discharge box plays the role of the middle rod sliding inside the material trough by its own gravity; The material discharging mechanism also includes a fixed plate, an elastic material-blocking flap and a spring sheet. The elastic material-blocking flap is connected to the inner side of the fixed plate through a movable shaft. The inner side of the elastic material-blocking flap is used to block and limit the centering rod. A spring sheet is fixed between the elastic material-blocking flap and the fixed plate. A storage mechanism is installed at the bottom of the main body, which includes a fixed box and a sliding box. The sliding box is located inside the fixed box, and the sliding box can be slid out relative to the fixed box to achieve the function of taking materials. An opening is opened on the top of the fixed box below the two sets of rotating support mechanisms.

[0006] By adopting the above technical solution, the middle rod is automatically fed and positioned by the electric push rod linked to the material clamp, avoiding placement deviation caused by manual operation, and cooperating with the positioning structure of the rotating support mechanism to ensure the consistency of the position of the middle rod in each test. During the test, the cooperation between the pressing head and the pressure sensor can accurately collect strength data, and the data is displayed in real time on the display screen with adjustable angle, which is convenient for observation and recording. At the same time, when the electric push rod rises, it drives the rotating support mechanism to rotate through the transmission of the tooth plate and the gear, so that the tested middle rod automatically falls into the storage mechanism, forming an automated cycle of loading, testing and unloading, reducing manual intervention. In addition, the discharge mechanism of the device realizes the orderly arrangement of the middle rods through the inclined design and the elastic material blocking flap, and the sliding box of the storage mechanism facilitates the removal of the middle rod after testing. The overall structure is compact and easy to maintain, which effectively solves the problems of low efficiency and poor accuracy of traditional manual detection, and is suitable for batch quality inspection needs in large-scale production.

[0007] Furthermore, the strength detection mechanism also includes a mounting plate and a connecting plate. The electric push rod is fixedly connected to the main body through the mounting plate, and there are two groups of connecting plates, which are respectively installed and fixed on the top and bottom of the pressure sensor. The connecting plate at the top is fixedly connected to the output end of the electric push rod, and the connecting plate at the bottom is fixedly connected to the pressing head.

[0008] By adopting this technical solution, the design of connecting two sets of connecting plates at the output end and sandwiching a pressure sensor in between can accurately transmit the pressure of the electric push rod, allowing the pressure sensor to accurately collect pressure data applied to the badminton shaft in real time, providing a reliable numerical basis for strength testing. The pressing head fixed at the bottom end matches the curved surface of the badminton shaft, and when pressure is applied, it acts evenly on the surface of the shaft, avoiding detection deviations caused by uneven force, thereby improving the accuracy and reliability of strength testing and ensuring that the test results truly reflect the actual strength performance of the carbon fiber badminton shaft.

[0009] Furthermore, a display screen is rotatably connected to one side of the main body, and a base is fixed to the bottom of the main body.

[0010] By adopting the above technical solution, the display screen is convenient for viewing the strength test data, and the base plays a supporting and fixing role for the entire main body, making it more stable during the strength test.

[0011] To sum up, the present invention mainly has the following beneficial effects: the present invention realizes automatic feeding and positioning of the middle rod through the linkage of the electric push rod and the material clamp, avoids placement deviation caused by manual operation, cooperates with the positioning structure of the rotating support mechanism to ensure the consistency of the position of the middle rod in each test, and during the test, the cooperation between the pressing head and the pressure sensor can accurately collect strength data, and the data is displayed in real time on a display screen with adjustable angle, which is convenient for observation and recording. At the same time, when the electric push rod rises, it drives the rotating support mechanism to rotate through the transmission of the tooth plate and the gear, so that the tested middle rod automatically falls into the storage mechanism, forming an automated cycle of loading, testing, and unloading, reducing manual intervention. In addition, the discharge mechanism of the device realizes orderly arrangement of the middle rods through the inclined design and the elastic material blocking flap, and the sliding box of the storage mechanism facilitates the removal of the middle rod after testing. The overall structure is compact and easy to maintain, which effectively solves the problems of low efficiency and poor accuracy of traditional manual detection, and is suitable for batch quality inspection needs in large-scale production.

[0014] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0015] The following describes an embodiment of the present invention based on its overall structure. Example 1

[0016] like Figure 1-12 As shown, this embodiment is based on a carbon fiber badminton shaft strength testing device. Its structural design focuses on automated batch testing and precise positioning. It mainly consists of a main body 1, a strength detection mechanism 2, a rotation support mechanism 3, a material discharge mechanism 4, and a storage mechanism 5. The main body 1 is made of aluminum alloy frame, with a fixed base 7 at the bottom, one side is connected to the display screen 6 for adjusting the display angle, the top of the interior is installed with a strength detection mechanism 2, the two sides of the bottom are symmetrically provided with a rotation support mechanism 3, one end is provided with a discharge mechanism 4, and the bottom is built-in with a storage mechanism 5; The display screen 6 is connected to the main body 1 via a hinge and can be rotated 180 degrees to display the intensity data collected by the pressure sensor 204. When not in use, it can be folded to the side of the main body and fixed; The electric push rod 202 is fixed to the top of the main body 1 through the mounting plate 201. The output end is connected to two sets of connecting plates 203, with a pressure sensor 204 sandwiched in the middle, and a pressing head 205 fixed at the bottom; A connecting rod 206 is fixed to the outside of the electric push rod 202, and the bottom is connected to a fixed frame 207. Four sets of material-moving clamps 208 are evenly distributed below the frame, which are used to move the middle rod when descending. The other end of the connecting rod 206 is fixed to a transmission rod 209, which is connected to a tooth plate 210 and meshes with the gear 309 of the rotating support mechanism 3. A fixed guide rod 211 that cooperates with the tooth plate 210 is fixed in the main body 1. The tooth plate 210 reciprocates and rises and falls along the fixed guide rod 211 through a sliding sleeve to ensure the stability of the tooth plate 210 when sliding; Two sets of support plates 301 are fixed to the bottom of the main body 1. The rotating shaft 303 passes through the support plates 301 and is rotatably connected to the rotating column 302. Support arms 304 are fixed to the four corners of the outer side of the column. A placement rod 305 is installed at the end. The rod body is equipped with two sets of positioning rings 306 and rubber rings 307. The middle anti-compression rod 308 enhances the structural strength. A gear 309 is sleeved on the outside of the rotating shaft 303 and connected to the rotating shaft 303 through a one-way bearing 310. The gear 309 only allows the rotating shaft 303 to rotate in one direction, thereby achieving the angle switching of the support arm 304. The tilted discharge box 401 of the discharge mechanism 4 has a built-in material trough 402, a fixed plate 403 at the end, and an elastic material-blocking flap 404 hinged by a spring sheet 405 to prevent the middle rod from sliding down automatically. It opens only when the material-dispensing clamp 208 is pressed down; The fixed box 501 is embedded in the bottom of the main body 1, and the sliding box 502 can be pulled out to receive the middle rod after testing. The opening is located below the rotating support mechanism 3; Batch loading and positioning Feeding operation: according to the actual situation, multiple carbon fiber badminton shafts are placed in the top of the feeding box 401 in sequence. The shafts slide down the inclined feeding trough 402 and are stopped by the elastic material stopping flap 404 and arranged in a single row. First material shifting: The electric push rod 202 starts to descend, and the material shifting clamp 208 is inserted between the two front middle rods. Its inclined portion presses down and pushes the first middle rod inward, so that the middle rod presses down the elastic material blocking flap 404, causing the first middle rod to slide out. The material shifting clamp 208 continues to descend and pushes the middle rod onto the two sets of placement rods 305. The positioning ring 306 limits the left and right displacement of the middle rod, and the rubber ring 307 provides friction to prevent rolling; Strength testing process Pressure detection: The electric push rod 202 continues to descend, and the pressing head 205 applies pressure to the middle part of the middle rod. The pressure sensor 204 collects data in real time, and the data is synchronously displayed on the display screen 6. When the pressure reaches a preset threshold or the middle rod breaks, the electric push rod stops descending; Data recording: Display 6 automatically records peak pressure and deformation. The staff can mark pass / fail on the touch screen, and the data is stored in the device memory; Automatic unloading and circulation After the test is completed, the electric push rod 202 rises, the gear plate 210 moves up with the transmission rod 209, the meshing gear 309 rotates 90 degrees, the one-way bearing 310 drives the rotating shaft 303 to rotate, the support arm 304 tilts, and the tested middle rod slides to the sliding box 502; Second loading: The electric push rod 202 returns to the initial position, the next set of support arms 304 just rotate to the horizontal position, the material clamp 208 descends again, and the material selection, testing, and unloading process is repeated. The test interval for each batch is about 15 seconds, which is 5 times more efficient than manual testing. Maintenance and calibration Regular calibration: Use a standard load block to calibrate the pressure sensor 204 to ensure detection accuracy, and check the rotation flexibility of the one-way bearing 310 to avoid angular deviation caused by jamming; Cleaning and maintenance: Clean the dust in the discharge box 401 and the sliding box 502 every week, check whether the material clip 208 is deformed, and ensure that the middle rod can be sent smoothly.

[0017] The working principle of the present invention is as follows: when in use, the power is turned on, wherein the electrical panel is electrically connected to the external power supply device through the power line, and then the electrical panel is electrically connected to the display screen 6 through the signal line and the power line, and then the compressive strength of the middle shaft of the carbon fiber badminton shaft can be displayed on the display screen 6; At the same time, the display screen 6 is located on one side of the main body 1 and is rotatably connected thereto, so that the orientation angle of the display screen 6 can be adjusted, making it more convenient for staff to observe. At the same time, when not in use, the display screen 6 is rotated to the side of the main body 1, where a positioning bar is fixed on one side of the main body 1, and the outer frame of the display screen 6 is snapped into the inner side of the positioning bar, thereby fixing the display screen 6 to keep it stable. When the strength of the middle rods of carbon fiber badminton shafts needs to be tested in batches, the staff first puts the middle rods cut in batches into the material trough 402 from the top of the material discharge box 401 in turn. Since the structure of the material discharge box 401 is inclined, after the middle rods enter the material trough 402, they can slide down to the inner end of the material trough 402 under the action of their own gravity. Moreover, since the elastic material blocking flap 404 is provided at the bottom of the material discharge box 401, the elastic material blocking flap 404 blocks the first group of middle rods entering the material trough 402 under the action of the spring sheet 405. Then the staff puts the remaining middle rods into the interior of the material trough 402 in turn. At this time, the overall gravity of the multiple groups of middle rods is less than the elastic force of the spring sheet 405, so the problem of the middle rods sliding out over the elastic material blocking flap 404 will not occur. In the early stage of the test, the corresponding support arms 304 of the two sets of rotating support mechanisms 3 are in a horizontal state, and the placement rods 305 fixed at the ends of the support arms 304 can play the role of bearing the centering rod; When the strength test of the middle rod is required, the electric push rod 202 of the strength testing mechanism 2 drives the structure connected to its output end to descend as a whole. Specifically, the bottom of the output end of the electric push rod 202 is fixedly connected to the first group of connecting plates 203, the pressure sensor 204, the second group of connecting plates 203 and the pressing head 205 connected at the bottom in sequence. The outer side of the output end of the electric push rod 202 is also fixed with a connecting rod 206, wherein the bottom of the connecting rod 206 drives the multiple groups of material clips 208 to descend through the fixed frame 207; When the electric push rod 202 descends, the end of one side of the material clip 208 will pass through the material discharge box 401 and then be inserted between the first and second groups of middle rods. At this time, as the material clip 208 descends, the upper structure of the material clip 208 gradually shrinks inwardly, and under the action of the inclined portion, the first group of middle rods gradually press down the elastic material blocking flap 404, so that the first group of middle rods pass over the elastic material blocking flap 404 and slide along the inner side of the end of the material discharge box 401; At this time, as the material-diverting clamp 208 continues to descend, the first set of middle rods is gradually pushed above the two sets of support arms 304. Since the structure above the material-diverting clamp 208 is two sets of parallel vertical structures, the first set of middle rods gradually moves to the middle position between the two sets of placement rods 305, so that the two sets of positioning rings 306 on the placement rods 305 play a role in positioning the first set of middle rods. Furthermore, when the first group of middle rods passes over the elastic material-blocking flap 404, the elastic return of the spring sheet 405 causes the elastic material-blocking flap 404 to return to its initial state, and the second group of middle rods is blocked and limited again. As the electric push rod 202 continues to descend, the first set of middle rods is pushed to the middle position between the two sets of placement rods 305 by the material clip 208. At this time, the pressing head 205 presses down the first set of carbon fiber middle rods. Under the action of the pressure sensor 204, the strength data of the middle rods can be detected and then displayed on the display screen 6. When the test of the first set of middle rods is completed, the structure connected to its output end rises as a whole under the action of the electric push rod 202. At this time, the two sets of transmission rods 209 connected by the connecting rod 206 will drive the corresponding gear plates 210 to rise, so that the rising gear plates 210 will drive the gears 309 to rotate, so that the two sets of rotating columns 302 will rotate synchronously inward along the rotating shaft 303. At this time, the two sets of placement rods 305 will contact and support the first set of middle rods, so that the tested middle rods of the first set will fall into the sliding box 502 of the storage mechanism 5 below, thereby completing the strength test of the first set of middle rods. When the electric push rod 202 rises to the initial position, the gear 309 rotates exactly 90 degrees under the action of the tooth plate 210, so that the next set of support arms 304 outside the rotating column 302 rotates to the horizontal position again, which can play a role in supporting the next set of middle rods; Furthermore, when the tooth plate 210 rises, the one-way bearing 310 is provided between the gear 309 and the rotating shaft 303. Thus, the gear 309 rotates under the action of the tooth plate 210 without driving the rotating shaft 303 to rotate. As a result, the two sets of rotating support mechanisms 3 do not rotate, thereby avoiding any impact on the center pole test process. According to the above, through the different reciprocating lifting operations of the electric push rod 202, the reciprocating operation of the above structure can be used to continuously and sequentially perform batch automatic testing on multiple groups of center rods, effectively avoiding the existing technology that, when performing batch testing on the center rod strength, the staff needs to manually place each center rod one by one on the testing equipment for strength testing, resulting in deviations in the placement position of the center rod affecting the strength test accuracy of the center rod. At the same time, it also effectively reduces the labor intensity of the staff, improves overall testing efficiency, and well meets the rapid testing needs of large-scale production, with good use effect.
