Description

TECHNICAL FIELD

[0001] The present application relates to the field of clamps, in particular to a clamp for watch part machining. BACKGROUND

[0002] Watch part machining refers to the manufacturing process of transforming raw materials (such as metals, plastics, gemstones, etc.) into various precision parts required for watches through a series of specific processes and technical means. This process covers multiple links from initial material preparation to the final formation of watch parts with specific shapes, sizes and functions, involving various processing methods and high-precision operations to ensure that the parts can meet the strict requirements of watches in terms of precision, reliability and aesthetics.

[0003] Clamps are process equipment used for clamping, positioning and fixing watch parts to facilitate various machining operations. Due to the rich and diverse shapes of watch parts, many parts are not regular geometric shapes. The existing clamps are difficult to closely match the complex contours of such parts when clamping them, resulting in uneven distribution of contact points. During the machining process, the parts are prone to slight displacement or rotation due to uneven stress, which affects the machining accuracy, causing the size deviation of the machined parts to exceed the allowable range, increasing the surface roughness, and even possibly leading to part scrap.

[0004] In view of the related technology in the above, the inventors believe that the watch parts are not stable when clamped by the clamp due to the influence of the connection shape, therefore, a clamp for watch part machining is proposed to solve the above problems. CONTENT OF THE INVENTION

[0008] Preferably, the spacing adjusting mechanism comprises a connecting block fixedly installed below the machining table through a connecting sliding block, a bidirectional screw rod rotatably installed at the bottom end of the machining table through the connecting block, and a rotating handle installed outside the machining table at one side of the bidirectional screw rod.

[0009] Preferably, through holes are formed in the front and rear ends of the support frame through a plurality of clamping pieces, and a through long groove is formed in the through holes, and a movable pull rod is movably installed in the through long groove.

DETAILED DESCRIPTION

[0018] The following will be described in detail in combination with the accompanying Figs. 1-3This application will be described in further detail.

[0019] This application discloses a fixture for machining watch parts. (Refer to...) Figs. 1-3 A fixture for processing watch parts includes a processing table 1. Guide grooves 2 are provided through both the front and rear ends of the upper surface of the processing table 1. A support frame 4 is symmetrically and movably installed on the upper surface of the processing table 1. Connecting sliders 3 are symmetrically welded to the bottom edge of the support frame 4 into the guide groove 2. A fixing groove 5 is provided in the middle of one side of the support frame 4. An inner groove 6 is provided on one side of the inner wall of the fixing groove 5. Clamping members 7 are movably installed side by side inside the fixing groove 5. The thickness of the upper and lower ends of the clamping members 7 is less than the distance between the upper and lower ends of the inner wall of the fixing groove 5, and adjacent clamping members 7 are close to each other. One side of the clamping member 7 has an arc-shaped structure. Several limiting balls 8 are placed inside the inner groove 6. A spacing adjustment mechanism is also provided below the processing table 1 to control the movement of the support frame 4.

[0020] By placing the watch part in the middle of the upper surface of the processing table 1, the connecting block 11, connected by the connecting slider 3, drives the support frame 4 to move along the upper surface of the processing table 1, so that the two support frames 4 move closer to each other and drive the clamping member 7 to abut against the outer surface of the part. Depending on the structure of the part, the clamping member 7 is pushed to abut against different positions of the part, and the clamping member 7 moves along the inside of the fixed groove 5 by different distances, so that the clamping member 7 pushes multiple limiting balls 8 to move along the inside of the placement inner groove 6 and embeds them into the inside of the multiple limiting balls 8. Then, the placement position of the multiple limiting balls 8 in the placement inner groove 6 is adjusted so that they limit and resist the clamping member 7 embedded at different depths, thereby clamping the watch part and placing it on the upper surface of the processing table 1.

[0021] Reference Fig. 1 and Fig. 2 The spacing adjustment mechanism includes a connecting block 11, which is fixedly installed below the processing table 1 through the connecting slider 3. A bidirectional lead screw 12 is rotatably installed at the bottom of the processing table 1 through the connecting block 11. A rotating handle 13 is installed on one side of the bidirectional lead screw 12 extending to the outside of the processing table 1. A threaded hole is opened through the middle of one side of the connecting block 11. External threads with opposite thread patterns are opened on both sides of the outer surface of the bidirectional lead screw 12. The bidirectional lead screw 12 and the threaded hole are mutually compatible.

[0022] By rotating the handle 13, the bidirectional lead screw 12 is rotated, causing the connecting block 11 to move along the outer surface of the bidirectional lead screw 12, thereby adjusting the distance between the two connecting blocks 11, so that the connecting block 11 drives the connecting slider 3 to move along the inside of the guide groove 2.

[0023] Reference Fig. 1 and Fig. 3The through long grooves 9 are internally movably provided with movable pull levers 10, and the through long grooves 9 and the movable pull levers 10 are mutually embedded.

[0024] By pulling the movable pull levers 10 to move along the inside of the through long grooves 9, the movable pull levers 10 simultaneously drive the multiple clamping pieces 7 to synchronously move and reset to the flush state, which is helpful for the subsequent clamping and limiting of the clamping pieces 7 on other clock parts.

[0025] The implementation principle of the clamp for clock part machining is as follows: the clock part is placed on the middle position of the upper surface of the machining table 1, the two-way screw rod 12 is rotated by rotating the rotating handle 13, the connecting blocks 11 are moved along the outer surface of the two-way screw rod 12, the distance between the two connecting blocks 11 is adjusted, the connecting blocks 11 drive the support frames 4 to move along the upper surface of the machining table 1 under the connection of the connecting sliding blocks 3, the two support frames 4 are moved close to each other to drive the clamping pieces 7 to abut against the outer surface of the part, according to the different structures of the parts, the clamping pieces 7 at different positions are pushed to abut against different positions of the part, the clamping pieces 7 are moved different distances along the inside of the fixed grooves 5, the multiple limiting balls 8 are moved along the inside of the placing inner grooves 6 and embedded in the inside of the multiple limiting balls 8, the placement positions of the multiple limiting balls 8 in the placing inner grooves 6 are adjusted, the multiple limiting balls 8 limit and resist the clamping pieces 7 embedded to different depths, and the movable pull levers 10 are pulled to move along the inside of the through long grooves 9, the movable pull levers 10 simultaneously drive the multiple clamping pieces 7 to synchronously move and reset to the flush state, which is helpful for the subsequent clamping and limiting of the clamping pieces 7 on other clock parts.
