Description

Technical Field

[0001] This utility model relates to the field of wrench processing technology, and in particular to a processing device for a movable ratchet wrench. Background Technology

[0002] A ratchet wrench is a manual tightening / removing tool with a one-way ratchet drive. Its core feature is "one-way drive, reverse free rotation," allowing for fastening operations without repeated wrench angle adjustments. It is suitable for scenarios such as mechanical repair and automotive maintenance, improving efficiency in confined spaces or high-frequency operations. Ratchet wrenches include fixed-size ratchet wrenches, socket ratchet wrenches, torque ratchet wrenches, and adjustable-head ratchet wrenches. An adjustable-head ratchet wrench is a manual tightening / removing tool with an adjustable head and integrated one-way ratchet drive.

[0003] Machining the arc-shaped structure at the wrench head connection end is a critical process, requiring a disc milling cutter in conjunction with a CNC milling machine. Precision milling is performed on the wrench head end according to the designed arc curvature parameters to ensure a smooth and continuous arc surface. However, currently, the wrench head is machined manually with individual clamping, which is not only inefficient but also compromises clamping stability. Therefore, designing a compact machining device that improves the machining efficiency of the wrench head connection end is a pressing technical problem that needs to be solved in this project. Utility Model Content

[0020] The following is for reference. Figure 1-4 Describe this utility model; A processing apparatus for a movable ratchet wrench, comprising: The base plate 100 is plate-shaped and is fixedly mounted on the machine tool worktable, with a mold core mounting position on the top; A crossbeam 200 is vertically mounted on top of the base plate 100. The crossbeam 200 is driven to move up and down on the base plate 100 by a pair of symmetrically arranged linear lifting mechanisms 210. The linear lifting mechanism 210 in this invention includes a cylinder, a hydraulic cylinder, or an electric push rod. The crossbeam 200 is provided with oblong adjustment holes that adapt to the multiple pressure rods 300, facilitating the adjustment of the pressure rod 300 position to match the bottom wrench 500.

[0021] Multiple pressure rods 300 are provided and are installed on the crossbeam 200 for vertical movement. The pressure rods 300 are pressed downward by springs 310. Specifically, the top of the pressure rod 300 is provided with a limiting nut that can be adjusted up and down by a thread, and the bottom is provided with a limiting part 320 for limiting the spring 310; The diameter of the limiting part 320 is larger than the rod diameter of the pressure rod 300.

[0022] The mold core 400 is mounted on a mold core mounting position, and the mold core mounting position structure restricts the horizontal movement of the mold core 400. The top surface of the mold core 400 has multiple machining grooves that are adapted to the wrench head 500. The pressure rod 300 is pressed down onto the wrench head 500 in the machining groove by a spring 310 sleeved on its surface. The side of the mold core 400 is provided with a handle for easy replacement of the mold core 400.

[0023] The connecting end of the wrench 500 extends out from the machining groove.

[0024] A pair of symmetrically arranged limiting blocks 110 are provided on the mold core mounting position, and the limiting block 110 has an L-shaped cross-section; The mold core 400 has a pair of notches that are adapted to the limit block 110.

[0025] A pair of clamps 600 are provided on the base plate 100; After the mold core 400 is installed in the mold core mounting position, the front end is limited by a pair of limiting blocks 110, and the rear end is fixed in the horizontal direction by a pair of clamps 600.

[0026] The method of use in this case is as follows: A row of cavities for placing workpieces side by side is machined into the mold core 400. The contour of the cavity matches the workpiece (wrench head). The workpieces to be processed are placed into the cavity of the mold core 400 in sequence. Then, the mold core 400 with the workpieces is placed into the limiting block 110 of the base plate 100. The clamp 600 behind the mold core is pushed. Then, the crossbeam 200 with spring pressure rods is pressed down by the linear drive mechanism 210. Each workpiece is completely fixed on the mold core 400. Because the thickness of the workpieces has tolerance and is inconsistent, the pressure rod 300 with springs can still press each workpiece tightly through the individual force of each spring 310. No workpiece will be loose. Then, the product is processed by moving the worktable horizontally. Two sets of mold cores 400 are used alternately to improve processing efficiency.
