Description

Technical Field

[0001] This invention relates to the field of ratchet ring processing, and more specifically, to a ratchet ring processing apparatus and processing method. Background Technology

[0002] A ratchet is a gear with rigid toothed surfaces or friction surfaces on its outer or inner edge, and it is an important component of a ratchet mechanism. Because ratchet mechanisms, such as ratchet rings, have the characteristic of unidirectional engagement and limiting, they are widely used in the wrench industry.

[0003] During the processing of ratchet rings, grooves need to be cut into the outer wall of the ratchet ring. Most existing ratchet ring processing devices use rolling or extrusion methods for grooving; however, this grooving method tends to result in large chamfers at the ends of the grooves, which are prone to slippage; furthermore, the torque accuracy of ratchet rings processed using this method is difficult to meet high usage requirements. Summary of the Invention

[0004] This invention provides a ratchet ring processing device and processing method, which can overcome the defects of the prior art where the end chamfer of the outer wall groove of the ratchet ring is large and the torque accuracy of the ratchet ring does not meet the high requirements of use.

[0005] The ratchet ring processing apparatus according to the present invention includes a horizontally arranged mounting platform, and a movable seat and a clamping seat are arranged opposite to each other on one end face of the mounting platform; the movable seat is movably connected to the mounting platform and can move along the length and width directions of the mounting platform; a rotating component and a processing component are respectively arranged on the outer walls of the clamping seat and the movable seat, and the rotating component and the processing component are arranged opposite to each other and at corresponding heights;

[0006] The rotating assembly is rotatable relative to the clamping seat, and the end of the rotating assembly far from the clamping seat is provided with an assembly part for assembling the blank; the machining assembly includes a tool assembly and a forging assembly arranged at intervals; the tool assembly is used to cooperate with the forging assembly to machine the blank, and the side of the forging assembly near the rotating assembly is provided with a forging inner hole, the forging inner hole is adapted to the size of the blank, and a forging part is formed on the inner wall of the forging inner hole for slotting on the outer wall of the blank.

[0007] Specifically, during the use of the ratchet ring processing device of the present invention, the movable seat movably connected to the mounting platform can better drive the processing components to move, thereby ensuring that the processing personnel can adjust the position of the processing components in real time to meet the processing requirements of different processes.

[0008] Furthermore, the rotating assembly can position the blank to be processed and drive it to rotate to cooperate with the tool assembly for rotary cutting. Notably, compared with the prior art, the present invention uses a forging process to groove the outer wall of the blank, and the chamfer at the end of the groove is small and does not easily slip; and the roughness generated during the forging process can be removed by rotary cutting with the tool assembly, thus obtaining a ratchet ring with better quality and higher torque accuracy.

[0009] Preferably, the rotating assembly includes a drive motor and a rotating shaft, with the output end of the drive motor connected to the rotating shaft; the assembly part is an assembly groove located on the side of the rotating shaft away from the drive motor and coaxial with the rotating shaft.

[0010] The assembly slot and drive motor in this invention can better fix and drive the blank to rotate in order to cooperate with the tool assembly for rotary cutting.

[0011] Preferably, the tool assembly includes a first tool, a second tool, and a third tool; the first tool is used to perform rotary cutting on the outer wall of the blank to form a smooth surface; the second tool is used to perform rotary cutting on both ends of the blank in the axial direction to form a chamfer; and the third tool is used to perform rotary cutting on the roughness formed on the blank after forging by the forging assembly.

[0012] The present invention, by using a first tool, a second tool, and a third tool set at fixed positions on the moving base, can better cooperate with the moving base for automated processing, thereby improving processing efficiency.

[0013] Preferably, the cutting portions of the first and third tools are on the same plane as the plane of symmetry in the height direction of the blank and the edges of the cutting portions are at right angles, and the cutting portion of the second tool is on the same plane as the plane of symmetry in the height direction of the blank and a triangular notch is formed at the edge of the cutting portion.

[0014] The present invention ensures that the cutting edge of the blank does not deviate from the center during the rotary cutting process of the first and third cutters by keeping the rotary cutting parts of the first and third cutters at the corresponding height.

[0015] In addition, the triangular notch formed at the edge of the second cutting tool's rotary cutting section can better chamfer both ends of the blank in the axial direction.

[0016] Preferably, the forging assembly includes a mounting base and a forging sleeve rotatably connected to the mounting base, with the forging inner hole coaxially located on the side of the forging sleeve near the blank.

[0017] The forging sleeve ensures a stable relative position between the forging inner hole and the blank to be processed, guaranteeing smooth and stable forging. Simultaneously, the forging sleeve is rotatably connected to the mounting base, allowing it to rotate synchronously with the blank. Therefore, the forging process can be synchronized with the rotation process, eliminating the need for operators to shut off the drive motor to stop the blank's rotation during forging, thus simplifying the processing steps and further improving efficiency.

[0018] The ratchet ring machining method according to the present invention, implemented by the aforementioned ratchet ring machining apparatus, includes the following steps:

[0019] Step S1: Assemble the blank into the mounting slot of the rotating shaft;

[0020] Step S2: Start the drive motor to drive the blank to rotate through the rotating shaft. Adjust the position of the moving seat so that the cutting part of the first tool corresponds to the blank in the width direction of the mounting platform. After adjusting the position, control the moving seat to drive the first tool to move towards the blank along the length direction of the mounting platform. The first tool performs rotary cutting on the outer wall of the blank to form a smooth surface.

[0021] Step S3: Keep the blank rotating and groove the outer wall of the blank using the forging assembly;

[0022] Step S4: Keep the blank rotating, adjust the position of the moving seat so that the third tool and the blank are in the same position in the width direction, and control the moving seat to drive the third tool to move along the length direction of the mounting platform to remove the roughness formed during the forging process of the blank.

[0023] Step S5: Keep the blank rotating, adjust the position of the moving seat so that the second cutter and the blank are in the same position in the width direction, and control the moving seat to drive the second cutter to move along the length direction of the mounting platform to turn the blank at both ends in the axial direction to form a chamfer.

[0024] Step S6: Remove the blank from the rotating shaft to complete the ratchet ring machining.

[0025] In the above processing method, after the blank is assembled, the position and usage sequence of the processing components at the moving seat are determined, so the ratchet ring can be automatically processed through the set process, which has high production efficiency.

[0026] Preferably, in the aforementioned ratchet ring machining method, step S3 includes the following steps:

[0027] Step S31: Keep the blank rotating while adjusting the position of the moving seat so that the forging sleeve and the axis of the blank are in the same straight line;

[0028] Step S32: After the position of the moving seat is adjusted, control the moving seat to drive the forging sleeve to move along the length of the installation platform toward the blank so that the forging sleeve and the blank rotate synchronously.

[0029] Step S33: Control the forging sleeve to move along the length of the installation platform, and the forging part at the inner wall of the forging inner hole grooves the outer wall of the blank.

[0030] By following the above steps, the forging process can be kept stable, and the chamfer at the end of the groove on the outer wall of the blank is smaller, making it less prone to slippage and achieving higher torque accuracy. Attached Figure Description

[0031] Figure 1 This is a schematic diagram of the ratchet ring processing device in Example 1; Detailed Implementation

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides a ratchet ring processing device, characterized in that: it includes a horizontally arranged mounting platform 110, and a movable seat 130 and a clamping seat 120 are arranged opposite each other on one end face of the mounting platform 110; the movable seat 130 is movably connected to the mounting platform 110, and the movable seat 130 can move along the length and width directions of the mounting platform 110; a rotating component and a processing component are respectively arranged on the outer walls of the clamping seat 120 and the movable seat 130, and the rotating component and the processing component are arranged opposite each other and at corresponding heights;

[0035] The rotating assembly is rotatable relative to the clamping seat 120. One end of the rotating assembly far from the clamping seat 120 is provided with an assembly part for assembling the blank 160. The machining assembly includes a tool assembly 170 and a forging assembly arranged at intervals. The tool assembly 170 is used to cooperate with the forging assembly to machine the blank 160. The forging assembly is provided with a forging inner hole on the side near the rotating assembly. The forging inner hole is adapted to the size of the blank 160, and a forging part is formed on the inner wall of the forging inner hole for slotting on the outer wall of the blank 160.

[0036] Specifically, during the use of the ratchet ring processing device in this embodiment, the movable seat 130, which is movably connected to the mounting platform 110, can better drive the processing components to move, thereby ensuring that the processing personnel can adjust the position of the processing components in real time to meet the processing requirements of different processes.

[0037] Furthermore, the rotating assembly can position the blank 160 to be processed and drive it to rotate to cooperate with the tool assembly 170 for rotary cutting. Notably, compared with the prior art, this embodiment uses a forging process to create a groove on the outer wall of the blank 160, resulting in a small chamfer at the end of the groove that is less prone to slippage; and the roughness generated during forging can be removed by rotary cutting using the tool assembly 170, thus obtaining a ratchet ring with better quality and higher torque accuracy.

[0038] Specifically, in this embodiment, the rotating assembly includes a drive motor 140 and a rotating shaft 150, with the output end of the drive motor 140 connected to the rotating shaft 150; the assembly part is an assembly groove located on the side of the rotating shaft 150 away from the drive motor 140 and coaxial with the rotating shaft 150.

[0039] The assembly slot and drive motor 140 in this embodiment can be used to fix and drive the blank 160 to rotate in order to cooperate with the tool assembly 170 for rotary cutting.

[0040] In detail, the tool assembly 170 includes a first tool 171, a second tool 172, and a third tool 173; the first tool 171 is used to perform rotary cutting on the outer wall of the blank 160 to form a smooth surface; the second tool 172 is used to perform rotary cutting on both ends of the blank 160 in the axial direction to form a chamfer; and the third tool 173 is used to perform rotary cutting on the roughness formed on the blank 160 after forging by the forging assembly.

[0041] By using the first tool 171, the second tool 172, and the third tool 173, which are fixedly positioned at the moving base 130, automated machining can be performed in better coordination with the moving base 130, thereby improving machining efficiency.

[0042] In this embodiment, the cutting portions of the first cutter 171 and the third cutter 173 are on the same plane as the plane of symmetry in the height direction of the blank 160 and the edges of the cutting portions are at right angles. The cutting portion of the second cutter 172 is on the same plane as the plane of symmetry in the height direction of the blank 160 and a triangular notch is formed at the edge of the cutting portion.

[0043] By keeping the cutting portions of the first cutter 171 and the third cutter 173 at the corresponding height, it can be ensured that the cutting edge of the blank 160 does not deviate from the center during the cutting process of the first cutter 171 and the third cutter 173 on the blank 160.

[0044] In addition, the triangular notch formed at the edge of the rotary cutting part of the second tool 172 can better chamfer both ends of the blank 160 in the axial direction.

[0045] In this embodiment, the forging assembly includes a mounting base 180 and a forging sleeve 190 rotatably connected to the mounting base 180, with the forging inner hole coaxially disposed on one side of the forging sleeve 190 near the blank 160.

[0046] The forging sleeve 190 ensures a stable relative position between the forging inner hole and the blank 160, guaranteeing smooth and stable forging. Simultaneously, the forging sleeve 190 is rotatably connected to the mounting base 180, allowing it to rotate synchronously with the blank 160. Therefore, the forging process of the blank 160 can be synchronized with its rotation, eliminating the need for the operator to shut off the drive motor 140 to stop the blank 160's rotation during forging. This simplifies the processing steps and further improves efficiency.

[0047] This embodiment provides a ratchet ring machining method, implemented using the aforementioned ratchet ring machining device, which includes the following steps:

[0048] Step S1: Assemble the blank 160 into the assembly slot of the rotating shaft 150.

[0049] Step S2: Start the drive motor 140 to drive the blank 160 to rotate via the rotating shaft 150. Adjust the position of the moving seat 130 so that the rotary cutting part of the first cutter 171 and the blank 160 are in the same position in the width direction of the mounting platform 110. After adjusting the position, control the moving seat 130 to drive the first cutter 171 to move along the length direction of the mounting platform 110 toward the blank 160. The first cutter 171 performs rotary cutting on the outer wall of the blank 160 to form a smooth surface.

[0050] Step S3: Keep the blank 160 rotating and groove the outer wall of the blank 160 through the forging assembly;

[0051] Step S4: Keep the blank 160 rotating, adjust the position of the moving seat 130 so that the third cutter 173 and the blank 160 are in the same position in the width direction, and control the moving seat 130 to drive the third cutter 173 to move along the length direction of the mounting platform 110 to remove the roughness formed during the forging process of the blank 160 by rotary cutting.

[0052] Step S5: Keep the blank 160 rotating, adjust the position of the moving seat 130 so that the second cutter 172 and the blank 160 are in the same position in the width direction, and control the moving seat 130 to drive the second cutter 172 to move along the length direction of the mounting platform 110 to turn the blank 160 at both ends in the axial direction to form a chamfer.

[0053] Step S6: Remove the blank 160 from the rotating shaft 150 to complete the ratchet ring machining.

[0054] In the above processing method, after the blank part 160 is assembled, since the position and usage sequence of the processing components at the moving seat 130 are determined, the ratchet ring can be automatically processed through the set process, which has high production efficiency.

[0055] Specifically, in the aforementioned ratchet ring machining method, step S3 includes the following steps:

[0056] Step S31: Keep the blank 160 rotating, and at the same time adjust the position of the moving seat 130 so that the forging sleeve 190 and the axis of the blank 160 are in the same straight line.

[0057] Step S32: After the position of the movable seat 130 is adjusted, control the movable seat 130 to drive the forging sleeve 190 to move along the length of the mounting platform 110 toward the blank 160 so that the forging sleeve 190 and the blank 160 rotate synchronously.

[0058] Step S33: Control the forging sleeve 190 to move along the length of the mounting platform 110, and the forging at the inner wall of the forging inner hole grooves the outer wall of the blank 160.

[0059] The above steps ensure the stability of the forging process and result in a smaller chamfer at the end of the groove on the outer wall of the blank (160mm), making it less prone to slippage and providing higher torque accuracy.

This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto.
