TECHNICAL FIELD

[0001] The present application relates to the technical field of bicycle production, in particular to a bicycle fork tube positioning tool. BACKGROUND

[0002] In the production and manufacturing process of the bicycle front fork, accurately drilling the inner wall step surface is a crucial link, which directly affects the stability of the subsequent brake disc installation and the safety of riding.

[0003] Traditional fork tube positioning tools mostly rely on workers manually rotating the screw to drive the clamping block to clamp the fork tube, to ensure the accuracy of the drilling position. However, since the number of bicycle front fork drilling is relatively small, the entire processing time is short, which requires workers to frequently and quickly rotate the screw back and forth to complete the clamping and positioning of different fork tubes. This process not only increases the labor intensity of workers and reduces production efficiency, but also may affect drilling accuracy due to human operation errors, thereby affecting product quality.

[0004] In addition, the current fork tube positioning tools on the market generally lack adaptability, and most of the tool designs are relatively simple, often only clamping specific size fork tubes, lacking the necessary adjustment flexibility. With the diversified development of the bicycle market, different brands and models of front fork tubes have different sizes, and traditional tools have been difficult to meet the diversified production needs.

[0009] Further, the upper surface of the positioning table is provided with a group of adjusting holes, and the top end of each of the two inner wall limiting blocks is inserted with a group of bolts. The bottom end of each bolt is threadedly connected with the adjusting hole adjacent thereto.

[0010] Through the above scheme, the spacing between the two inner wall limiting blocks can be adjusted by the bolts and adjusting holes, so as to achieve the purpose of fixing and clamping the fork pipe with different diameters.

[0011] Further, one side of each of the two outer wall clamping plates approaching each other is provided with a sawtooth shape.

[0012] Through the above scheme, the friction coefficient between the fork pipe and the clamping plate can be increased by the above setting, so as to improve the stability of fixing.

[0013] Further, the bottom of the positioning table is fixedly connected with a connecting plate, and a group of connecting holes are formed in the upper surface of the connecting plate.

[0017] Further, the front surface of the frontmost shaft plate is provided with a motor, and the output end of the motor is fixedly connected with the front end of the bidirectional threaded rod.

[0018] Through the above scheme, the rotation of the bidirectional threaded rod can be powered by the motor.

[0019] Further, the two inner wall limiting blocks are both U-shaped.

[0020] Through the above scheme, through the above setting, the step surface of the inner wall of the fork tube can be avoided from being blocked, and the drilling device is avoided from interfering with the drilling of the fork tube.

[0021] Further, the two inner wall limiting blocks and the two outer wall clamping plates are made of high-strength wear-resistant alloy steel.

[0022] Through the above scheme, through the use of high-strength wear-resistant alloy steel, the tooling can have sufficient strength and wear resistance to withstand high load and friction during drilling, thereby prolonging the service life of the tooling.

[0023] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 One side of the two outer wall clamping plates 4 that approach each other is provided in a sawtooth shape, through the above setting, the friction coefficient with the fork tube can be increased, and then the fixing stability is improved, the upper surface of the positioning table 1 is provided with a group of adjusting holes 5, the top end of the two inner wall limiting blocks 2 is inserted with a group of bolts 6, the bottom end of each bolt 6 is threadedly connected with the adjusting hole 5 close to it, through the setting of the bolt 6 and the adjusting hole 5, the user can conveniently adjust the distance between the two inner wall limiting blocks 2, and then the purpose of fixing and clamping the fork tube with different diameters is achieved.

[0036] Please refer to Figure 1 , Figure 2 and Figure 4The bottom of the positioning table 1 is fixedly connected with a connecting plate 7, a group of connecting holes 8 are formed in the upper surface of the connecting plate 7, through the arrangement of the connecting holes 8, the connecting plate 7 can be connected with an external workbench, two shaft plates 9 are fixedly connected between the left and right inner side walls of the positioning table 1, a bidirectional threaded rod 10 is rotatably connected between the two shaft plates 9, the bottom ends of the two outer wall clamping plates 4 are threadedly connected with the two ends of the bidirectional threaded rod 10, through the arrangement of the bidirectional threaded rod 10, the two outer wall clamping plates 4 can be driven to move close to or away from each other, the front surface of the frontmost shaft plate 9 is provided with a motor 11, the output end of the motor 11 is fixedly connected with the front end of the bidirectional threaded rod 10, through the arrangement of the motor 11, power can be provided for the rotation of the bidirectional threaded rod 10.

[0037] The bicycle fork tube positioning tool in the embodiment can drive the bidirectional threaded rod 10 to rotate through the motor 11, so that the two outer wall clamping plates 4 can quickly and stably move close to or away from each other, thereby realizing quick clamping and positioning of fork tubes with different diameters. This design not only improves production efficiency, but also significantly reduces the labor intensity of workers, so that the entire drilling process is more efficient and convenient. The inner wall limiting blocks 2 can be flexibly adjusted in spacing through the cooperation of the bolts 6 and the adjusting holes 5 to adapt to fork tubes of different sizes. This design enhances the versatility and flexibility of the tool, reduces production interruptions caused by tool replacement, and reduces production costs. The surface of the outer wall clamping plate 4 is designed in a sawtooth shape, which effectively increases the friction coefficient between the outer wall clamping plate 4 and the fork tube, thereby improving the stability of clamping.

[0038] It should be noted that before starting the motor 11 and adjusting the inner wall limiting blocks 2, it is necessary to ensure that there is no debris on the positioning table 1. When adjusting the spacing of the inner wall limiting blocks 2, ensure that the spacing between the two inner wall limiting blocks 2 matches the diameter of the fork tube to be processed, to ensure the stability of clamping and the accuracy of drilling. To ensure long-term stable operation of the tool, the positioning table 1, the inner wall limiting blocks 2, the outer wall clamping plate 4 and the bidirectional threaded rod 10 need to be cleaned and lubricated regularly, and the bolts 6 and the connecting holes 8 need to be checked for looseness or wear. Damaged parts should be replaced in time to prolong the service life of the tool.

[0039] The working principle of the above embodiment is as follows: first, according to the diameter of the fork tube to be machined, the adjusting hole 5 is selected by rotating the bolt 6 to adjust the distance between the two inner wall limit blocks 2 to adapt to fork tubes of different sizes. After adjustment, ensure that the inner wall limit blocks 2 are firmly fixed in the desired position. Place the bicycle fork tube to be machined on the positioning table 1 so that its inner wall is in contact with the two inner wall limit blocks 2. The U-shaped design of the inner wall limit blocks 2 ensures that the stepped surface of the inner wall of the fork tube is not blocked, leaving space for subsequent drilling operations. Start the motor 11, and the output shaft of the motor 11 drives the bidirectional threaded rod 10 to rotate. Since the bottom ends of the two outer wall clamps 4 are respectively threaded with the two ends of the bidirectional threaded rod 10, as the threaded rod rotates, the two outer wall clamps 4 will quickly and smoothly move towards each other along the sliding groove 3 until the fork tube is tightly clamped between the outer wall clamps 4 and the inner wall limit blocks 2. The sawtooth design on the surface of the outer wall clamps 4 increases the friction between the fork tube and the outer wall clamps 4, improving the stability of the clamping. After the fork tube is stably clamped, the drilling device can start to accurately drill the stepped surface of the inner wall of the fork tube. Since the fork tube is firmly fixed, it will not shake during drilling, thereby ensuring the accuracy of the drilling position and the smoothness of the hole wall. After completing the drilling operation, turn off the motor 11 and rotate the bidirectional threaded rod 10 in the opposite direction to move the two outer wall clamps 4 away from each other to release the fork tube. Then, remove the machined fork tube and repeat the above steps to prepare for processing the next fork tube.
