[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:
[0027] This utility model provides a precision machining device for watch movement parts, including a device body 1. The device body 1 is provided with an assembly support block 2 for convenient support of various components. The assembly support block 2 has a through hole in the middle for the locking rod 5 of the part to pass through. A bearing ring groove is provided inside the left end of the through hole for the locking rod 5 of the part to be installed by bearing. A locking screw hole is provided on the bottom wall of the right end of the through hole for the rotating locking pin 3 to be installed by thread. Fixed thread blind holes are provided on both the front and back of the left end face of the assembly support block 2 for the fixed guide rod 4 to be installed by thread. Downward thread blind holes are provided on both the front and back of the right side of the top end face of the assembly support block 2 for the downward pressing pin 8 of the part to be installed by thread. A trapezoidal groove is provided in the middle of the top end face of the assembly support block 2 for the watch movement parts to be placed and positioned. A rotating locking pin 3 is installed inside the locking screw hole of the bearing block 2 to facilitate tightening and preventing rotation of the part locking rod 5. The rotating locking pin 3 has threads on its outer circumference for easy installation. A regular hexagonal groove is provided on the bottom end face of the rotating locking pin 3 to facilitate rotation and disassembly using tools. A fixed guide rod 4 is installed inside the fixed threaded blind hole of the assembly bearing block 2 to facilitate guiding the part locking block 7. The right end of the fixed guide rod 4 has threads on its outer circumference for easy assembly with the assembly bearing block 2. A regular hexagonal groove is provided on the left end face of the fixed guide rod 4 to facilitate rotation and disassembly using tools. The part locking rod 5 is installed inside the bearing ring groove of the assembly bearing block 2 via a bearing, facilitating rotation of the part locking rod 5 via the bearing. A rotating pin with an anti-slip groove is provided on the right end of the part locking rod 5 to facilitate rotation and prevent slippage.
[0028] The locking rod 5 has a fixed post on its left end face, which facilitates its installation via bearings. The fixed post of the locking rod 5 has a threaded rod on its left end face, which facilitates the installation of the locking block 7 via threads. The threaded rod of the locking rod 5 has a threaded blind hole on its left end face, which facilitates the installation of the anti-detachment post 6 via threads. The anti-detachment post 6 is installed inside the threaded blind hole of the locking rod 5, which helps prevent the locking block 7 from detaching. The anti-detachment post 6 has an anti-detachment circular plate in the middle, which helps to block and prevent the locking block 7 from detaching. The anti-detachment circular plate of the anti-detachment post 6 has a threaded post on its right end face, which facilitates its installation via threads. The anti-detachment circular plate of the anti-detachment post 6 has a regular hexagonal prism on its left end face, which facilitates disassembly and assembly with tools. The locking block 7 is installed on the threaded rod of the locking rod 5 via threads, which allows the locking block 7 to move left and right through thread engagement. The locking block 7 has a threaded hole in the middle. The threaded holes running through the left and right sides facilitate the installation of the threaded rod of the locking rod 5. The locking block 7 has guide holes running through the left and right sides at both ends to facilitate the insertion of the guide rod 4. The top end face of the locking block 7 has blind holes with downward threaded holes on both the front and back sides on the left side to facilitate the installation of the downward pressing column 8 through the thread. The top end face of the locking block 7 has a trapezoidal groove running through the left and right sides in the middle to facilitate the placement and limiting of the watch movement parts. The downward pressing column 8 is installed inside the blind holes with downward threaded holes of the locking block 7 and the assembly bearing block 2, so that the downward pressing column 8 can descend and press the watch movement parts. The lower part of the downward pressing column 8 is provided with a threaded rod to facilitate the lifting and lowering of the downward pressing column 8 through threaded engagement. The top outer circumference of the threaded rod of the downward pressing column 8 is provided with a pressing ring plate to facilitate pressing the watch movement parts. The top end face of the threaded rod of the downward pressing column 8 is provided with a regular hexagonal groove to facilitate the rotation and tightening with tools.
[0029] The specific usage and function of this embodiment are as follows:
[0030] In this utility model, such as Figure 1 As shown, the device body 1 is in use. At this time, the watch movement part is clamped between the trapezoidal grooves of the assembly support block 2 and the part locking block 7. The part pressing column 8 presses against the top of the watch movement part, solving the problem that the watch movement part is prone to warping due to force during clamping. At the same time, the rotating locking column 3 presses against the rotating column of the part locking rod 5, as shown in the figure. Figure 3 As shown, the locking rod 5 is prevented from rotating by rotating the locking pin 3, thus solving the problem that the locking rod is prone to rotation due to accidental operation, causing the watch movement parts to be released from the clamping state. Figure 1As shown, when disassembling the watch movement parts between the trapezoidal grooves of the assembly support block 2 and the part locking block 7, the part pressing column 8 is rotated with a tool to engage with the threaded connection of the assembly support block 2, and the part pressing column 8 is rotated with a tool to engage with the threaded connection of the part locking block 7. This causes the part pressing column 8 to rise through the threaded engagement, releasing the pressure on the watch movement parts. The rotating locking column 3 is rotated with a tool to engage with the threaded connection of the assembly support block 2, causing the rotating locking column 3 to descend through the threaded engagement, releasing the pressure on the rotating column of the part locking rod 5. This releases the rotating locking column 3 from locking the part locking rod 5. The part locking rod 5 is rotated to engage with the threaded connection of the part locking block 7, causing the part locking block 7 to move to the left through the threaded engagement, thereby releasing the clamping of the watch movement parts. Then, the watch movement parts can be removed.
[0031] Example 2: The difference from Example 1 is that the regular hexagonal prism of the fixed anti-detachment column 6 can also be set as a regular heptagonal prism, so that the fixed anti-detachment column 6 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed anti-detachment column 6.
[0032] Example 3: The difference from Example 1 is that the regular hexagonal groove of the part pressing column 8 can also be set as a regular heptagonal groove. This makes the part pressing column 8 require a special tool that cooperates with the regular heptagonal groove to rotate, thus preventing non-workers from rotating and disassembling the part pressing column 8.
