Technical Field
[0001] The utility model belongs to the technical field of a device for correcting the central axis of a mountain bike pedal axle before turning, and more specifically, relates to a device for correcting the central axis of a mountain bike pedal axle before turning. Background Art
[0002] The center axis correction device of the mountain bike pedal axle before turning generally refers to a device used to ensure the accuracy and centering of the pedal axle during the manufacturing process, ensuring that the rotation axis of the wheel and pedal is in the correct position, thereby improving the overall riding performance and durability.
[0003] Some mountain bike pedal axles currently have a center axis correction device before turning. When a measuring instrument is used to measure deformation of the pedal axle or a non-linear center axis, a hydraulic cylinder is usually used to drive a pressing head to press down on the deformed part of the pedal axle to correct it. However, although this correction method is more efficient, it is prone to internal stress, resulting in deformation of the pedal axle and shortening of fatigue life. It also affects the physical and mechanical properties of the pedal axle.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a correction device for the center axis of the mountain bike pedal axle before turning is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0006] The top end face of the sliding panel also is provided with an interlocking structure, and the interlocking structure is pivotally connected to the base plate, and the interlocking structure is pivotally connected to the base plate, and the interlocking structure is pivotally connected to the base plate.
[0007] Furthermore, a rotating block 1 is installed at one end of the rotating shaft 1 away from the three-jaw chuck.
[0008] Furthermore, a chamber is provided in the mounting seat below the movable groove, one side of the chamber is rotatably connected to a second rotating shaft, one end of the second rotating shaft is installed with an active bevel gear, and the other end of the second rotating shaft passes through one side of the mounting seat and is installed with a second rotating block.
[0009] Furthermore, the top of the chamber is rotatably connected to a second screw rod, the bottom end of the second screw rod is installed with a driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed with each other.
[0010] Furthermore, a thread groove is provided on the bottom end surface of the support block, and the top end of the second screw rod extends into the thread groove and is threadably connected to the thread groove.
[0011] Furthermore, an adjusting block is installed at one end of the screw rod away from the heater.
[0012] Furthermore, a pair of limiting rods are installed on one side of the heater near the position of the screw rod 1, and the length of the limiting rods is equal to the length of the screw rod 1.
[0013] Furthermore, the upper end surface of the support block is provided with a groove.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] By cooperating with the rotating block 2, the rotating shaft 2, the active bevel gear, the driven bevel gear, the screw rod 2 and the threaded groove, when the three-jaw chuck clamps one end of the pedal shaft, the rotating block 2 is rotated, and the rotating block 2 drives the active bevel gear through the rotating shaft 2, and the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the screw rod 2 to rotate in the threaded groove, so that the support block moves upward until the groove on the upper end surface of the support block fits with the surface of the pedal shaft, thereby achieving the effect of supporting pedal shafts of various sizes.
[0016] By using the adjustment block, screw 1, and heater in conjunction, when the measuring instrument detects a deformed position on the pedal shaft, the operator begins rotating the adjustment block, which drives screw 1. Since screw 1 is threadedly connected to the support block, the rotation of screw 1 drives the heater to one side to the deformed position. The heater is then activated to heat the deformed position of the pedal shaft. After heating is complete, it is corrected, making its internal structure more uniform and eliminating internal stress, thereby improving the physical and mechanical properties of the steel plate.

A limit block 501 is movably connected in the movable groove 401, and a support block 5 is installed on the upper end surface of the limit block 501. A screw rod 6 is threadedly connected to one side of the support block 5, and a heater 11 is rotatably connected to one end of the screw rod 6. A mounting plate 102 is installed on one side of the upper end surface of the workbench 1, and a mounting frame 7 is installed on the upper end surface of the mounting plate 102. A hydraulic cylinder 701 is installed on the top of the mounting frame 7, and a pressure block 702 is installed on the output end of the hydraulic cylinder 701. An "L"-shaped rod 703 is installed on one side of the upper end of the mounting frame 7, and a measuring instrument 12 is installed on the bottom of the "L"-shaped rod 703.
[0028] Among them, a rotating block 302 is installed at one end of the rotating shaft 301 away from the three-jaw chuck 10, and the rotating block 302 drives the three-jaw chuck 10 to rotate through the rotating shaft 301.
[0029] Among them, a chamber 402 is provided below the movable groove 401 in the mounting seat 4, and a rotating shaft 2 8 is rotatably connected to one side of the chamber 402. An active bevel gear 801 is installed at one end of the rotating shaft 2 8, and a rotating block 2 802 is installed on the other end of the rotating shaft 2 8 passing through one side of the mounting seat 4.
[0030] The top of the chamber 402 is rotatably connected to a screw rod 9 , and a driven bevel gear 901 is installed at the bottom end of the screw rod 9 . The driving bevel gear 801 and the driven bevel gear 901 are meshed with each other.
[0031] Among them, the bottom end surface of the support block 5 is provided with a thread groove 502, and the top end of the screw rod 9 extends into the thread groove 502 and is threadedly connected to the thread groove 502.
[0032] Among them, an adjustment block 601 is installed at the end of the screw rod 6 away from the heater 11, and the adjustment block 601 drives the screw rod 6 to rotate.

[0035] The working principle of this embodiment is as follows:
[0036] First, use the three-jaw chuck 10 to clamp one end of the pedal shaft, and then rotate the rotating block 2 802. The rotating block 2 802 drives the active bevel gear 801 through the rotating shaft 2 8. The active bevel gear 801 drives the driven bevel gear 901 to rotate. The driven bevel gear 901 drives the screw rod 2 9 to rotate in the thread groove 502, so that the support block 5 moves upward until the groove 503 on the upper end face of the support block 5 fits with the surface of the pedal shaft. Then adjust the measuring instrument 12 so that the bottom end of the measuring instrument 12 fits with the surface of the pedal shaft. At this time, start to rotate the rotating block 1 302. The rotating block 1 302 drives the three-jaw chuck 10 to rotate through the rotating shaft 1 301. The three-jaw chuck 10 drives the pedal shaft to rotate. When the pedal shaft is deformed, the staff member pushes the support seat 2 to slide to one side on the slider 101. If the pedal shaft is deformed, the value of the measuring instrument 12 will change. When the measuring instrument 12 measures the position where the pedal shaft is deformed, the staff member starts to rotate the adjusting block 601. The adjusting block 601 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the support block 5, the screw rod 6 drives the heater 11 to move to one side to the deformed position when it rotates. Then the heater 11 is started to heat the deformed position of the pedal shaft. After heating is completed, the hydraulic cylinder 701 is started again. The hydraulic cylinder 701 drives the pressure block 702 to move downward to correct the deformed part of the pedal shaft.
