Description

Technical Field

[0001] This utility model relates to the field of precision machining equipment technology, specifically to a high-precision multi-directional adjustment device for the spindle head of a high-density alloy automatic hammer Geneva stripe finishing equipment. Background Technology

[0002] High-density alloy automatic rotors are crucial components in mechanical watches. The surface of these rotors typically requires intricate decorative finishing, with Geneva stripes being a common high-end pattern. The processing of Geneva stripes demands extremely high precision and stability to ensure a uniform, delicate, and aesthetically pleasing finish.

[0003] Traditional Geneva stripe finishing equipment for automatic watch rotors typically uses a fixed or simply adjustable spindle head. Adjustment of the spindle head largely relies on manual operation or simple mechanical structures, resulting in a limited adjustment range that is insufficient to meet the demands of complex curved surfaces and high-precision machining. Specifically, the following problems exist:

[0004] 1. Insufficient adjustment precision: Manual adjustment is difficult to achieve micron-level high-precision positioning, which affects the processing quality of Geneva stripes.

[0005] 2. Poor flexibility: Traditional devices are difficult to make precise adjustments in multiple directions and angles, and cannot adapt to the processing needs of automatic gyroscopes of different shapes and sizes.

[0006] 3. Inefficiency: The adjustment process is cumbersome and time-consuming, making it difficult to meet the high-efficiency requirements of mass production.

The X-axis adjustment mechanism is used to adjust the X-axis angle of the spindle head 1, achieving high-precision displacement adjustment of the spindle head in the X-axis direction.

[0043] Y-axis adjustment mechanism

[0044] The Y-axis adjustment mechanism includes a Y-axis adjustment block 31, a Y-axis rotating shaft 23, a spindle head clamp 21, a Y-axis locking assembly, and a Y-axis measuring assembly.

[0045] The spindle head is fixed to the spindle head clamp 21. The spindle head clamp 21 is rotatably positioned on the Y-axis adjustment block 31 via the Y-axis rotating shaft 23. The Y-axis locking component is used to lock the spindle head clamp 21 (preventing it from rotating). The Y-axis measuring component is used to measure the Y-axis angle of the spindle head 1.

[0046] The spindle head clamp 21 includes two clamping arms 21-1. The inner side of the clamping arms is an arc surface that matches the shape of the spindle head. The front ends of the two clamping arms are fixed by clamping locking bolts 22, so the clamping arms clamp and fix the spindle head.

[0047] One end of the Y-axis rotating shaft 23 is tightly fitted with the clamping connection hole 21-2 of the spindle head clamp 21. The Y-axis fixing bolt 24 is screwed into the clamping positioning hole 21-3 on the bottom surface of the spindle head clamp 21 to hold the Y-axis rotating shaft 23 in place. The other end of the Y-axis rotating shaft is threaded and passes through the Y-axis center hole 31-1 of the Y-axis adjusting block 31 before being threadedly connected to the Y-axis connecting nut 25.

[0048] In the Y-axis locking assembly, the Y-axis adjusting block 31 is provided with two Y-axis adjusting grooves 31-2. These two Y-axis adjusting grooves are curved in an arc and located on both sides of the Y-axis center hole 31-1. The Y-axis center hole 31-1 is the center of the Y-axis adjusting groove 31-2. The clamping connection hole 21-2 of the spindle head clamp 21 is provided with Y-axis locking screw holes 21-4 on both sides.
