Description

Technical Field

[0001] The present invention relates to the field of sports equipment testing, and in particular to a golf club shaft strength testing device and method. Background Art

[0002] Golf is an ancient and popular sport, and golf clubs are an indispensable tool for this sport. A golf club typically consists of a club head, a shaft, and a grip. Currently, most common golf club shafts are hollow steel. After production, golf club shafts are tested for strength, and the results are used to grade the shafts.

[0003] Most existing devices squeeze the shaft a little to cause it to bend, and then use a pressure testing machine to detect the force generated by the bending of the shaft. As a result, most existing devices can only detect the bending force in a single direction. In addition, since the angle of the golf club is different when it hits the golf ball, the bending angle of the shaft is different each time, which makes it difficult for existing devices to simulate the various angles of bending of the shaft. In addition, since the positions of people's hands holding the golf club are different, the bending point of the golf club is located at different positions when it bends, which makes it difficult for existing devices to simulate real-life conditions to test the shaft of the golf club. Summary of the Invention

[0004] In order to overcome the shortcomings of existing equipment that most can only detect the bending force in a single direction and it is difficult to simulate the various angles of bending produced by the shaft, and the bending points of the shaft are at different positions, which makes it difficult for existing equipment to simulate the actual situation to detect the shaft of a golf club, the purpose of the present invention is to provide a golf club shaft strength detection device and method that can detect the bending force of a hollow shaft in different directions and can simulate the bending force of a hollow shaft at different bending points in actual situations, so that the bending strength detection of the hollow shaft is closer to the actual situation.

There are six rollers in total, and hollow rods are placed on four of the rollers.

[0016] As a further preferred solution, the hollow rod is conical.

[0017] As a further preferred solution, an adjustment mechanism is also included for adjusting the position of the slider, which is arranged on the transmission frame. The adjustment mechanism includes: a pushing frame slidably connected to the transmission frame, the pushing frame is fixedly connected to the slider, a compression spring fixed between the pushing frame and the transmission frame, a driven rod fixed to the pushing frame, and a contact plate fixed to the side of the guide frame, wherein the contact plate is in contact with the driven rod.

[0018] As a further preferred solution, two inclined surfaces are provided on the contact plate.

[0019] As a further preferred solution, a lifting mechanism is also included, which is used to keep the roller in contact with the hollow rod at all times and is arranged on the fixed plate. The lifting mechanism includes: an inclined plate fixed to the fixed plate, a lifting frame fixed to one of the mounting blocks, the lifting frame being slidably connected to the slider, an extrusion spring fixed between the slider and the lifting frame, and a contact block fixed to the lifting frame, wherein the contact block is in contact with the inclined plate.

[0020] As a further preferred solution, a limiting mechanism is also included for driving the driven rod to move, which is arranged on the baffle frame. The limiting mechanism includes: a contact rod slidably connected to the side of the baffle frame, two limiting blocks fixed to the side of the baffle frame, and card plates sliding on the two limiting blocks respectively, one of which is clamped with the contact rod.

[0022] The movement of the mounting block and roller on the slider causes the contact point between the roller and the hollow rod to change, and then the movement of the mounting block and roller on the slider causes the bending point of the hollow rod to change when it is deformed, which is used to simulate the force of the hollow rod at different bending points and cooperate with the bending of the hollow rod in different directions, thereby better simulating the bending force of the hollow rod at different bending points in real situations, so that the bending strength test of the hollow rod is closer to the actual situation.

[0023] The movement of the slider will drive the lifting frame, the extrusion spring and the contact block to move. When the contact block moves, it will be squeezed by the upper surface of the inclined plate to make the contact block move upward. The upward movement of the contact block will drive the lifting frame to move upward. The upward movement of the lifting frame will drive the mounting block and the roller on the slider to move upward. The mounting block and the roller on the slider will fit with the hollow rod when they move upward, so that the position of the bending point of the hollow rod can be controlled more accurately, thereby making it possible to more accurately simulate the actual bending situation of the hollow rod, thereby making the hollow rod more accurately simulate the actual situation.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1: A golf club shaft strength detection device and method, such as Figures 1-6 Shown: Includes:

[0037] Table 1;

[0040] A rotating frame 51 fixedly connected to the rotating shaft of the servo motor 5;

[0041] A pressing mechanism, used to detect the strength of the golf club, is provided on the fixing plate 2;

[0042] A swing mechanism, used for swinging the support point of the golf club, is provided on the pressing mechanism;

[0043] The locking mechanism is used to fix the golf club and is arranged on the fixing seat 3 and the swinging mechanism.

[0044] The pressing mechanism includes: a guide frame 61 welded on the fixed plate 2, a sliding frame 62 slidably connected to the guide frame 61, the sliding frame 62 is welded to the rotating frame 51, a hydraulic rod 63 connected to the sliding frame 62 by bolts, a lower pressing plate 64 slidably connected to the sliding frame 62, the telescopic rod of the hydraulic rod 63 is fixedly connected to the lower pressing plate 64, and a pressure detection machine 65 connected to the lower pressing plate 64 by bolts. The pressure detection machine 65 is used to detect the bending force.

[0045] The swing mechanism includes: a limiting bent rod 71 welded on the fixed seat 3, a swing frame 72 slidably connected to the limiting bent rod 71, the limiting bent rod 71 is used to limit the swing of the swing frame 72, a slider 73 slidably connected to the swing frame 72, a transmission frame 74 fixed on the swing frame 72, and the transmission frame 74 is welded to the sliding frame 62.

[0046] The locking mechanism includes: a locking bolt 81 rotatably connected to the fixed seat 3, a lower pressure frame 82 threadedly connected to the locking bolt 81, the lower pressure frame 82 slidingly connected to the fixed seat 3, a mounting block 83 connected to the fixed seat 3 by bolts, a mounting block 83 slidingly connected to the slider 73, two rollers 84 rotatably connected to the two mounting blocks 83 respectively, and two rollers 84 rotatably connected to the lower pressure frame 82. There are six rollers 84 in total, and hollow rods 85 are placed on four of the rollers 84.

[0047] The hollow rod 85 is tapered.

[0048] At first, the staff puts the hollow rod 85 on four of the rollers 84, and then the staff turns the locking bolt 81. The rotation of the locking bolt 81 will squeeze the lower pressing frame 82 downward through the thread, and the downward movement of the lower pressing frame 82 will drive the other two rollers 84 to move downward. The downward movement of the other two rollers 84 will clamp one end of the hollow rod 85. The staff no longer turns the locking bolt 81, and the staff starts the hydraulic rod 63. The downward movement of the telescopic rod of the hydraulic rod 63 will drive the lower pressing plate 64 to move downward a certain distance. The downward movement of the lower pressing plate 64 will drive the pressure detection machine 65 to move downward a certain distance. The downward movement of the pressure detection machine 65 will contact the other end of the hollow rod 85. The continued downward movement of the pressure detection machine 65 will make the hollow rod 85 The other end moves downward, causing the hollow rod 85 to bend with the roller 84 on the slider 73 as the bending point. After the pressure detection machine 65 moves downward a certain distance, the staff turns off the hydraulic rod 63. The force generated by the bending of the hollow rod 85 will be detected by the pressure detection machine 65, and then the staff will record the data on the pressure detection machine 65. After the staff completes the data recording, the staff restarts the hydraulic rod 63. The telescopic rod of the hydraulic rod 63 will drive the lower pressure plate 64 and the pressure detection machine 65 to reset. The staff turns off the hydraulic rod 63. After completing the bending force test of the hollow rod 85 in one direction, the staff starts the servo motor 5. The servo motor 5 will rotate between plus or minus 15 degrees. The servo motor 5 will drive the rotating frame 51 to rotate. The rotating frame The rotation of 51 will drive the sliding frame 62 to rotate, and the rotation of the sliding frame 62 will drive the hydraulic rod 63, the lower pressure plate 64, the pressure detection machine 65 and the transmission frame 74 to rotate. The rotation of the transmission frame 74 will drive the swing frame 72 and the slider 73 to rotate. The rotation of the slider 73 will drive the mounting block 83 and the roller 84 on the slider 73 to rotate. Then the staff turns off the servo motor 5, and then the staff restarts the hydraulic rod 63. The telescopic rod of the hydraulic rod 63 will drive the lower pressure plate 64 and the pressure detection machine 65 to move downward. The downward movement of the pressure detection machine 65 causes the hollow rod 85 to bend. The staff turns off the hydraulic rod 63, and the pressure detection machine 65 stops moving downward. The pressure detection machine 65 detects the bending force of the hollow rod 85 in different directions. Finally, the staff starts again The hydraulic rod 63 drives the lower pressure plate 64 and the pressure detection machine 65 to reset. After the reset is completed, the staff closes the hydraulic rod 63 and starts the servo motor 5. The servo motor 5 drives the rotating frame 51, the sliding frame 62, the hydraulic rod 63, the lower pressure plate 64, the pressure detection machine 65, the swing frame 72, the slider 73 and the transmission frame 74 to reset. The reset of the slider 73 will drive the mounting block 83 and the roller 84 on the slider 73 to reset. Then, this is repeated several times, so that the bending strength of the hollow rod 85 in different directions can be tested. The staff divides the grade of the hollow rod 85 according to the data detected in multiple directions, so that the bending strength of the hollow rod 85 can be tested from multiple angles, thereby making the bending strength test of the hollow rod 85 closer to reality.After the inspection is completed, the staff rotates the locking bolt 81. The rotation of the locking bolt 81 drives the lower pressing frame 82 and the roller 84 on the lower pressing frame 82 to move upward through the thread, so that the roller 84 on the lower pressing frame 82 no longer presses the hollow rod 85, and the staff removes the hollow rod 85.

[0049] Example 2: Based on Example 1, Figure 7 As shown, an adjustment mechanism is also included for adjusting the position of the slider 73, which is arranged on the transmission frame 74. The adjustment mechanism includes: a pushing frame 91 slidably connected to the transmission frame 74, the pushing frame 91 is fixedly connected to the slider 73, a compression spring 92 fixed between the pushing frame 91 and the transmission frame 74, a driven rod 93 welded to the pushing frame 91, and a contact plate 94 welded to the side of the guide frame 61, the contact plate 94 is in contact with the driven rod 93, and the contact plate 94 is used to push the driven rod 93.

[0050] The contact plate 94 is provided with two inclined surfaces.

[0051] Initially, the compression spring 92 is in a compressed state, and the rotation of the transmission frame 74 drives the pushing frame 91, the compression spring 92 and the driven rod 93 to rotate. The compression spring 92 in the compressed state pushes the driven rod 93 to close to the contact plate 94. The rotation of the driven rod 93 causes the driven rod 93 to move along the inclined surface of the contact plate 94. The movement of the driven rod 93 drives the pushing frame 91 to move. The movement of the pushing frame 91 drives the slider 73 to move along the swing frame 72. The movement of the slider 73 drives the mounting block 83 and the roller 84 on the slider 73 to move. The movement of the mounting block 83 and the roller 84 on the slider 73 causes the contact point of the roller 84 with the hollow rod 85 to change, thereby causing the mounting block 83 and the roller 84 on the slider 73 to move. The bending point of the hollow rod 85 changes when it is deformed, which is used to simulate the force of the hollow rod 85 at different bending points at different times, and cooperate with the bending of the hollow rod 85 in different directions, so that the bending force of the hollow rod 85 at different bending points in real situations can be better simulated, thereby making the bending strength test of the hollow rod 85 closer to the real situation. The rotation and reset of the transmission frame 74 will drive the push frame 91, the compression spring 92 and the driven rod 93 to rotate and reset. The rotation and reset of the driven rod 93 will move along the inclined surface of the contact plate 94. The movement of the driven rod 93 will drive the push frame 91 to reset. The reset of the push frame 91 will drive the slider 73 to reset. The reset of the slider 73 will drive the mounting block 83 and the roller 84 on the slider 73 to reset.

[0052] Example 3: Based on Example 2, Figure 6-Figure 9As shown, a lifting mechanism is also included for ensuring that the roller 84 is always in contact with the hollow rod 85, which is provided on the fixed plate 2. The lifting mechanism includes: an inclined plate 101 connected to the fixed plate 2 by bolts, the inclined plate 101 having an inclined surface, a lifting frame 102 connected to one of the mounting blocks 83 by bolts, the lifting frame 102 being slidably connected to the slider 73, an extrusion spring 103 fixed between the slider 73 and the lifting frame 102, and a contact block 104 welded to the lifting frame 102, the contact block 104 being in contact with the inclined plate 101.

[0053] Initially, the inclination of the inclined plate 101 is the same as the taper of the hollow rod 85, and the extrusion spring 103 is in a compressed state. The movement of the slider 73 drives the lifting frame 102, the extrusion spring 103 and the contact block 104 to move. At the same time, the movement of the slider 73 also drives the mounting block 83 and the roller 84 on the slider 73 to move. When the contact block 104 moves, it will be squeezed by the upper surface of the inclined plate 101, causing the contact block 104 to move upward. The upward movement of the contact block 104 will drive the lifting frame 102 to move upward, and the upward movement of the lifting frame 102 will make the extrusion spring 103 Further compression and the upward movement of the lifting frame 102 will drive the mounting block 83 and the roller 84 on the slider 73 to move upward. The upward movement of the mounting block 83 and the roller 84 on the slider 73 will fit with the hollow rod 85, so that the position of the bending point of the hollow rod 85 can be controlled more accurately, thereby making it possible to more accurately simulate the actual bending condition of the hollow rod 85, thereby making it possible to more accurately simulate the actual condition of the hollow rod 85. The reset of the slider 73 will drive the lifting frame 102, the extrusion spring 103, the contact block 104, the mounting block 83 and the roller 84 to reset.

[0054] Example 4: Based on Example 3, Figure 2-Figure 10 As shown, a limiting mechanism is also included for driving the driven rod 93 to move, which is provided on the baffle frame 4. The limiting mechanism includes: a contact rod 111 slidably connected to the side of the baffle frame 4, two limiting blocks 112 welded to the side of the baffle frame 4, and clamping plates 113 sliding on the two limiting blocks 112 respectively, wherein one of the clamping plates 113 is clamped with the contact rod 111.

[0055] At first, when there is no need to change the bending direction of the hollow rod 85 and move the bending point of the hollow rod 85 at the same time, the staff moves the card plate 113 engaged with the contact rod 111, so that the card plate 113 is out of contact with the contact rod 111, and then the staff moves the contact rod 111, and the contact rod 111 moves and contacts with the driven rod 93. The staff continues to push the contact rod 111 to move, and the contact rod 111 continues to move to push the driven rod 93 to move, and the driven rod 93 moves and disengages from the contact plate 94. The movement of the driven rod 93 drives the pushing frame 91 and the slider 73 to move. The movement of the pushing frame 91 compresses the compression spring 92, and the movement of the slider 73 drives the lifting frame 102, the extrusion spring 103, and the contact The staff then moves the other card plate 113 and inserts the other card plate 113 into the contact rod 111, so that the bending point of the hollow rod 85 will not be changed when the bending direction of the hollow rod 85 is changed, thereby making it possible to simulate more situations of the hollow rod 85. After the inspection is completed, the staff disengages the other card plate 113 from the contact rod 111, and then drives the contact rod 111 to reset, and the pushing frame 91 and the driven rod 93 are driven by the compression spring 92 to reset. The pushing frame 91 will drive the slider 73 to move, the lifting frame 102, the extrusion spring 103, the contact block 104 and the mounting block 83 and the roller 84 on the slider 73 to reset.
