It consists of main and secondary ratchet sleeves of different sizes connected by a hinge key with male and female interlocking keys.

[0003] Traditional methods of machining ratchet wrenches have several limitations. Firstly, machining accuracy is difficult to guarantee; when machining curved shapes, dimensional deviations and substandard surface roughness are prone to occur, affecting the performance and lifespan of the ratchet wrench. Secondly, machining efficiency is low; traditional machining equipment often requires multiple clamping and adjustments, increasing machining time and labor costs. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a ratchet wrench-type hand-held arc milling machine.

[0005] The objective of this utility model can be achieved through the following technical solution: a ratchet wrench swing-type hand-held arc milling machine, comprising a base, characterized in that a processing component and a clamping component are mounted on the base, the clamping component includes a worktable for working, a tooling fixture placed on the worktable for clamping a wrench, and a limiting unit for limiting the wrench, the tooling fixture having a tooling unit and a clamping unit, the tooling unit consisting of two symmetrical tooling seats with placement slots, a placement cavity for placing the wrench formed between the tooling seats, the clamping unit being respectively provided with a clamping seat and a clamping block, the clamping block having a telescopic rod and a limiting rod at the top, the telescopic rod having a cylinder block connected to the clamping seat, the limiting rod extending upward and penetrating the clamping seat, the clamping block having a limiting block at the front end, the worktable having an opening slot corresponding to the limiting block, and a push plate for cylinder pushing located at the other end of the tooling unit.

[0006] In the aforementioned ratchet-type hand-held arc milling machine, the limiting unit is composed of a front limiting seat and a left limiting seat. The front limiting seat is provided with a limiting piece, which can move flexibly by a cylinder located at its bottom.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, this ratchet wrench swing-type hand-held arc milling machine includes a base 1. A processing component 2 and a clamping component 3 are mounted on the base 1. The clamping component 3 includes a worktable 4 for working, a tooling fixture 5 placed on the worktable 4 for clamping a wrench, and a limiting unit 6 for limiting the wrench. The worktable 4 is mounted on the base 1, providing a mounting base for the tooling fixture 5 and the limiting unit 6. The tooling fixture 5 has a tooling unit 7 and a clamping unit 8. The tooling unit 7 consists of two symmetrical tooling seats 9 with placement slots. A placement cavity 10 for placing the wrench is formed between the tooling seats 9. The two tooling seats 9 are firmly mounted on the worktable 4 by bolts, forming a placement cavity 10 for placing the wrench between them. The dimensions of the placement cavity 10 are designed according to the specifications of the ratchet wrench, ensuring accurate positioning of the wrench during placement and preventing wobbling during processing. The clamping unit 8 is equipped with a clamping seat 11 and a clamping block 12. The clamping seat 11 is fixed to the worktable 4, providing support and guidance for the clamping block 12. The top of the clamping block 12 is equipped with a telescopic rod 13 and a limiting rod 14. A cylinder block 15 is mounted on the telescopic rod 13, connected to the clamping seat 11. Driven by the cylinder, the cylinder block 15 extends and retracts the telescopic rod 13, thereby enabling the clamping block 12 to move up and down. The limiting rod 14 extends upward and passes through the clamping seat 11. The limiting rod 14 restricts the movement direction of the clamping block 12 and prevents the clamping block 12 from deviating during movement. A limiting block 16 is provided on the front end of the clamping block 12. The worktable 4 is provided with an opening slot corresponding to the limiting block 16. When the clamping block 12 moves downward to clamp the wrench, the limiting block 16 enters the opening slot, further enhancing the clamping stability. A push plate 17 for cylinder pushing is provided on the other end of the tooling unit 7. By pushing the push plate 17, the wrench can enter the clamping block 12 more smoothly.

[0016] To elaborate further, the limiting unit 6 consists of a front limiting seat 18 and a left limiting seat 19. The front limiting seat 18 and the left limiting seat 19 are respectively installed in front of and to the left of the worktable 4, together forming the limiting unit 6. A limiting piece 20 is provided on the front limiting seat 18. The limiting piece 20 moves flexibly via a cylinder located at its bottom. When clamping the wrench, the cylinder pushes the limiting piece 20 up or down, precisely limiting the position of the wrench's front end. When the processing component 2 is working, the limiting... Position plate 20 moves downward to leave machining space for milling cutter 31. A limit plate 21 is provided in the left limit seat 19. The limit plate 21 is displaced by a cylinder. A limit groove 22 is provided on the worktable 4 for the limit plate 21 to enter. When clamping the wrench, the cylinder drives the limit plate 21 to enter the limit groove 22 to limit the left side of the wrench, ensuring the wrench is accurately positioned in the horizontal and vertical directions and improving machining accuracy.

[0017] In further detail, the machining assembly 2 includes a base 23, a slide rail seat 24 mounted on the base 23 with a slide rail, a fixed seat 25 placed on the slide rail seat 24, and a vertical machining seat 26 located on one side of the fixed seat 25. The fixed seat 25 is placed on the slide rail seat 24 and can move back and forth along the slide rail. By adjusting the position of the fixed seat 25, the machining direction can be changed. A fixed block 27 is provided on the vertical machining seat 26. A drive motor 28 is provided on the top of the fixed block 27, and a rotating machining part 29 is provided at the bottom of the fixed block 27. A machining shaft 30 is provided on the machining part 29. One end of the machining shaft 30 extends upward and is connected to the motor shaft of the drive motor 28 through a transmission belt, and the other end extends downward to the outside of the machining part 29. A milling cutter 31 for milling arcs on the wrench is mounted on the machining shaft 30. The drive motor 28 drives the machining shaft 30 to rotate through the transmission belt. The milling cutter 31 for milling arcs on the wrench is mounted on the machining shaft 30. During the processing, the drive motor 28 rotates at high speed and transmits power to the processing shaft 30 through the transmission belt, causing the milling cutter 31 to rotate at high speed, thereby realizing the milling of the arc of the wrench body.

[0018] To elaborate further, one side of the clamping assembly 3 is provided with a discharge tray 32 for removing the processed wrench, and the discharge tray 32 is inclined. After processing is completed, the push plate 17 pushes the wrench to fall onto the feeding tray, and then slides out of the machine tool through the inclined feeding tray.
