Description

Technical Field

[0001] This invention relates to the field of strength testing equipment technology, specifically to a carbon fiber badminton shaft strength testing device. Background Technology

[0002] In the manufacturing process of carbon fiber badminton shafts, strength testing is a key step in ensuring product quality and performance. Currently, the industry's common strength testing method involves taking multiple sets of badminton racket shafts from the production batch as test samples. Workers manually place each shaft onto the testing equipment one by one. During testing, the pressure head of the testing equipment descends to apply pressure to the shaft, and relevant data is collected and recorded by sensors 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, staff need to repeatedly pick up and place the center rod, resulting in low testing efficiency and difficulty in meeting the rapid testing needs of large-scale production. On the other hand, during the manual placement of the center rod, different staff members have different operating habits and strengths. Even if the same staff member operates, it is difficult to ensure that the placement position of each group of center rods on the testing equipment is completely consistent. The slight deviation in the placement position of the center rod will cause changes in the point and direction of pressure applied by the pressure head, which will affect the accuracy of the data collected by the sensor and ultimately reduce the overall testing accuracy. This makes it impossible for the test results to truly and reliably reflect the actual strength performance of the carbon fiber badminton shaft. Summary of the Invention

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

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber badminton shaft strength testing device, comprising a main body, wherein a strength testing mechanism is installed at the top of the main body, and a rotating support mechanism is installed on both sides of the bottom of the main body;

[0006] The rotating support mechanism consists of a set of rotating columns and support arms fixed at the four outer corners. Each set of support arms has a placement rod fixed at its end, and the placement rod serves to support the central 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 serves to apply pressure to the central rod.

[0007] The rotating support mechanism also includes a support plate and a pressure-resistant rod. The rotating shaft passes through the support plate and is rotatably connected to it. The support plate provides support for the movement of the rotating support mechanism. Pressure-resistant rods are fixed between the four sets of support arms. The pressure-resistant rods strengthen the four sets of support arms. The rotating support mechanism also includes positioning rings and rubber rings. Two sets of positioning rings are fixed on the outside of each set of placement rods. The two sets of positioning rings provide a stabilizing position after the center rod is placed. The rubber ring is fixed at the middle position on the outside of the placement rod to stabilize the placement of the center rod.

[0008] The electric push rod output end is fixed with connecting rods on both sides. The bottom of the two sets of connecting rods is fixed with a fixed frame, and multiple sets of material feeding clamps are evenly fixed at the bottom of the fixed frame. The material feeding clamp is composed of two sets of plates. One set of plates is vertical, and the other set of plates consists of a vertical part, an inclined part, and a vertical part from bottom to top. The material feeding clamp descends to play the role of feeding the center rod.

[0009] The strength testing mechanism also includes a transmission rod and a toothed plate. One end of the transmission rod is fixedly connected to a connecting rod, and the other end is fixedly connected to the toothed plate. It is used to drive the toothed plate to lift and lower. The rotating 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 meshes with the toothed plate. When the toothed plate rises, it meshes with the gear, causing the rotating column to rotate, thus adjusting the angle of the rotating column.

[0010] The main body is equipped with a feeding mechanism at one end, and the feeding box of the feeding mechanism has a material groove that serves to arrange multiple sets of middle rods in sequence. The feeding box is also designed with an overall tilt, which allows the middle rods to slide inside the material groove by their own gravity.

[0011] The feeding mechanism also includes a fixed plate, an elastic baffle plate, and a spring sheet. The elastic baffle plate is connected to the inside of the fixed plate via a movable shaft. The inside of the elastic baffle plate is used to block and limit the center rod. A spring sheet is fixed between the elastic baffle plate and the fixed plate.

[0012] The main body is equipped with a storage mechanism at the bottom. The storage mechanism includes a fixed box and a sliding box. The sliding box is located inside the fixed box and can be slid out relative to the fixed box to retrieve materials. The fixed box has an opening at the top located below the two sets of rotating support mechanisms.

[0013] By adopting the above technical solution, the automatic feeding and positioning of the middle rod is achieved through the linkage of the electric push rod and the material clamp, avoiding placement deviations caused by manual operation. In conjunction with the positioning structure of the rotating support mechanism, the consistency of the middle rod position in each test is ensured. During the test, the pressing head and pressure sensor work together to accurately collect strength data, and the data is displayed in real time on an adjustable display screen for easy 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 toothed plate and gears, so that the middle rod after testing automatically falls into the storage mechanism, forming an automated cycle of feeding, testing, and unloading, reducing manual intervention. In addition, the unloading mechanism of the device achieves orderly arrangement of the middle rods through the tilting design and the elastic baffle 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, effectively solving the problems of low efficiency and poor accuracy of traditional manual testing, and is suitable for batch quality inspection needs in large-scale production.

[0014] Furthermore, the strength testing 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 sets 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.

[0015] By adopting the above technical solution, the design of connecting two sets of connecting plates at the output end and clamping a pressure sensor in the middle can accurately transmit the pressure of the electric push rod. This allows the pressure sensor to collect the pressure data applied to the badminton shaft in real time and accurately, providing reliable numerical data for strength testing. The pressing head fixed at the bottom matches the curved surface of the badminton shaft, ensuring that pressure is applied evenly to the shaft surface when applied, avoiding detection deviations caused by uneven force. This improves the accuracy and reliability of strength testing, ensuring that the test results truly reflect the actual strength performance of the carbon fiber badminton shaft.

[0016] Furthermore, a display screen is rotatably and adjustablely connected to one side of the main body, and a base is fixed to the bottom of the main body.

[0017] By adopting the above technical solution, the display screen facilitates the viewing of strength test data, and the base provides overall support and fixation for the main body, making it more stable during strength testing.

[0018] In summary, the present invention has the following advantages: The present invention achieves automatic feeding and positioning of the middle rod through an electric push rod linked to a material clamp, avoiding placement deviations caused by manual operation. Combined with the positioning structure of the rotating support mechanism, it ensures the consistency of the middle rod position in each test. During the test, the pressing head and pressure sensor work together to accurately collect strength data, which is displayed in real time on an adjustable-angle display screen for easy observation and recording. Simultaneously, when the electric push rod rises, it drives the rotating support mechanism to rotate through the transmission of the toothed plate and gears, causing the tested middle rod to automatically fall into the storage mechanism, forming an automated cycle of feeding, testing, and unloading, reducing manual intervention. Furthermore, the unloading mechanism of the device achieves orderly arrangement of the middle rods through an inclined design and an elastic baffle flap. The sliding box of the storage mechanism facilitates the removal of the tested middle rods. The overall structure is compact and easy to maintain, effectively solving the problems of low efficiency and poor accuracy in traditional manual testing, and is suitable for batch quality inspection needs in large-scale production.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 construed as limiting the present invention.

[0033] The embodiments of the present invention will now be described. Example 1

[0034] like Figure 1-12 As shown, this embodiment focuses 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 testing mechanism 2, a rotating support mechanism 3, a feeding mechanism 4, and a storage mechanism 5.

[0035] The main body 1 adopts an aluminum alloy frame, with a fixed base 7 at the bottom, a rotating display screen 6 on one side for adjustable display angle, a strength testing mechanism 2 installed at the top inside, rotating support mechanisms 3 symmetrically arranged on both sides of the bottom, a material feeding mechanism 4 at one end, and a built-in storage mechanism 5 at the bottom.

[0036] The display screen 6 is connected to the main body 1 via a hinge and can rotate 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 for fixation.

[0037] The electric push rod 202 is fixed to the top of the main body 1 by the mounting plate 201, the output end is connected to two sets of connecting plates 203, the pressure sensor 204 is clamped in the middle, and the pressing head 205 is fixed at the bottom.

[0038] The electric push rod 202 has a fixed connecting rod 206 on the outside and a fixed frame 207 at the bottom. Four sets of material feeding clamps 208 are evenly distributed below the frame for feeding the middle rod when it descends. The other end of the connecting rod 206 is fixed with a transmission rod 209, which is connected to a toothed plate 210 and meshes with the gear 309 of the rotating support mechanism 3. The main body 1 has a fixed guide rod 211 that cooperates with the toothed plate 210. The toothed plate 210 moves up and down along the fixed guide rod 211 through a sliding sleeve to ensure the stability of the toothed plate 210 when it slides.

[0039] Two sets of support plates 301 are fixed to the bottom of the main body 1. The rotating shaft 303 passes through the support plate 301 and is rotatably connected to the rotating column 302. Support arms 304 are fixed at 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.

[0040] 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. Only the gear 309 is allowed to drive the rotating shaft 303 to rotate in one direction, thereby realizing the angle switching of the support arm 304.

[0041] The inclined feeding box 401 of the feeding mechanism 4 has a built-in material trough 402 and a fixed plate 403 at the end. The elastic material blocking flap 404 is hinged by a spring sheet 405. The blocking rod slides down automatically and only opens when the material feeding clamp 208 is pressed down.

[0042] 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.

[0043] Batch feeding and positioning

[0044] Material feeding operation: According to the actual situation, multiple carbon fiber badminton shafts are placed into the top of the feeding box 401 in sequence. The shafts slide down along the inclined material groove 402 and are blocked by the elastic baffle 404, forming a single row.

[0045] Initial material feeding: The electric push rod 202 starts to descend, and the feeding clamp 208 is inserted between the two frontmost middle rods. Its inclined part presses down and pushes the first middle rod inward, so that the middle rod presses down on the elastic stop flap 404, causing the first middle rod to slide out. The feeding clamp 208 continues to descend, pushing the middle rod onto the two sets of placement rods 305. The positioning ring 306 restricts the left and right displacement of the middle rod, and the rubber ring 307 provides friction to prevent rolling.

[0046] Strength testing process

[0047] Pressure detection: As the electric push rod 202 continues to descend, the pressing head 205 applies pressure to the middle of the rod. The pressure sensor 204 collects data in real time, and the data is displayed on the display screen 6. When the pressure reaches the preset threshold or the rod breaks, the electric push rod stops descending.

[0048] Data recording: Display screen 6 automatically records peak pressure and deformation. Operators can mark qualified / unqualified data on the touch screen, and the data is stored in the equipment memory.

[0049] Automatic feeding and circulation

[0050] Unloading operation: After the test is completed, the electric push rod 202 rises, the toothed plate 210 moves up with the transmission rod 209, the meshing gear 309 rotates ninety degrees, the one-way bearing 310 drives the rotating shaft 303 to rotate, the support arm 304 tilts, and the middle rod after the test slides down to the sliding box 502.

[0051] Secondary feeding: Electric push rod 202 returns to the initial position, the next set of support arms 304 just rotates to the horizontal position, and the feeding clamp 208 descends again. The feeding, testing and unloading process is repeated. The test interval for each batch is about 15 seconds, which is 5 times more efficient than manual feeding.

[0052] Maintenance and Calibration

[0053] Regular calibration: Use a standard load block to calibrate the pressure sensor 204 to ensure detection accuracy, and check the rotational flexibility of the one-way bearing 310 to avoid jamming that could cause angular deviation;

[0054] Cleaning and maintenance: Clean the dust inside the feeding box 401 weekly, clean the sliding box 502, check whether the feeding clamp 208 is deformed, and ensure that the feeding of the center rod is smooth.

[0055] The working principle of this invention is as follows: When in use, the power is turned on, and the electrical panel is electrically connected to the external power supply equipment via the power cord. Then, the electrical panel is electrically connected to the display screen 6 via the signal line and the power cord, so that the compressive strength of the shaft of the carbon fiber badminton club can be displayed on the display screen 6.

[0056] Meanwhile, the display screen 6 is located on one side of the main body 1 and is rotatably connected to it, so the orientation angle of the display screen 6 can be adjusted, making it easier for staff to observe. When not in use, the display screen 6 can be rotated to the side of the main body 1, where a positioning strip is fixed on one side of the main body 1. The outer frame of the display screen 6 can be snapped into the inside of the positioning strip, thereby fixing the display screen 6 and keeping it stable.

[0057] When a batch of carbon fiber badminton shafts need to be tested for strength, the staff first inserts the cut shafts into the material trough 402 from the top of the material box 401. Due to the inclined design of the material box 401, the shafts slide down to the end of the trough 402 under their own weight. Since the bottom of the material box 401 is equipped with an elastic baffle 404, the elastic baffle 404 blocks the first set of shafts entering the trough 402 under the action of the spring plate 405. Then the staff inserts the remaining shafts into the trough 402 in turn. At this time, the total weight of the multiple sets of shafts is less than the elastic force of the spring plate 405, so the shafts will not slide out of the elastic baffle 404.

[0058] In the early stage of testing, the corresponding support arms 304 of the two sets of rotating support mechanisms 3 are in a horizontal state, and the placement rod 305 fixed at the end of the support arm 304 can play the role of bearing the center rod.

[0059] 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 sequentially fixed with a first set of connecting plates 203, a pressure sensor 204, a second set of connecting plates 203, and a pressing head 205 connected at the bottom. A connecting rod 206 is also fixed on the outside of the output end of the electric push rod 202. The bottom of the connecting rod 206 drives multiple sets of material feeding clamps 208 to descend through the fixing frame 207.

[0060] When the electric push rod 202 descends, the end of one side of the material feeding clamp 208 will pass through the material dispensing box 401 and then be inserted between the first and second group of middle rods. At this time, as the material feeding clamp 208 descends, the structure above the material feeding clamp 208 gradually forms an inwardly contracting inclined structure. Under the action of the inclined part, the first group of middle rods gradually press down on the elastic baffle 404, so that the first group of middle rods slides along the inner side of the end of the material dispensing box 401 past the elastic baffle 404.

[0061] At this time, as the material feeding 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 feeding clamp 208 is a set of two parallel vertical structures, the first set of middle rods gradually moves to the middle position on the two sets of placement rods 305, so that the two sets of positioning rings 306 on the placement rods 305 play a positioning role for the first set of middle rods.

[0062] Furthermore, when the first set of middle rods passes the elastic stop flap 404, the elastic stop flap 404 is reset to its initial state under the elastic reset of the spring plate 405, and the second set of middle rods is blocked and limited again.

[0063] As the electric push rod 202 continues to descend, the first set of middle rods is pushed to the middle position of the two sets of placement rods 305 by the material feeding clamp 208. At this time, the pressing head 205 will press down on the first set of carbon fiber middle rods. Under the action of the pressure sensor 204, the strength data of the middle rod can be detected and then displayed on the display screen 6.

[0064] After the first set of middle rods has been tested, 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 toothed plate 210 to rise. The rising toothed plate 210 will drive the gear 309 to rotate, so that the two sets of rotating columns 302 will rotate synchronously inward along the rotating shaft 303. Then, the two sets of placement rods 305 will contact each other to support and place the first set of middle rods, so that the middle rods that have completed the test fall into the sliding box 502 of the storage mechanism 5 below, thus completing the strength test of the first set of middle rods.

[0065] When the electric push rod 202 rises to the initial position, the gear 309 rotates exactly ninety degrees under the action of the toothed plate 210, so that the next set of support arms 304 on the outside of the rotating column 302 rotates to the horizontal position again, which can bear the load of the next set of middle rods.

[0066] Furthermore, when the toothed plate 210 rises, since a one-way bearing 310 is provided between the gear 309 and the rotating shaft 303, the gear 309 rotates under the action of the toothed plate 210 but does not drive the rotating shaft 303 to rotate. Thus, the two sets of rotating support mechanisms 3 will not rotate, avoiding any impact on the test of the central rod.

[0067] As described above, by using the electric push rod 202 in different reciprocating lifting operations, multiple sets of middle rods can be automatically tested in batches through the reciprocating operation of the above structure. This effectively avoids the problem in the prior art where workers need to manually place each middle rod onto the testing equipment for strength testing when conducting batch strength testing of the middle rods. This can lead to deviations in the placement of the middle rods, affecting the accuracy of the strength test. At the same time, it also effectively reduces the labor intensity of workers, improves the overall testing efficiency, and well meets the rapid testing needs of large-scale production. The results are good.
