Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polishing machines, in particular to a watch case polishing and clamping mechanism. Background Art
[0002] When processing a metal watch case, its surface needs to be polished. Since the watch case has a curved surface structure, it is usually difficult to polish all parts of its outer surface in one clamping. The watch case has a hollow structure, and the outer surface of the watch case needs to be polished. Therefore, it is necessary to use internal support to fix it. However, if the internal support is too strong, it is easy to cause deformation or damage to the workpiece. Utility Model Content
[0003] The utility model aims to provide a watch case grinding and clamping mechanism to solve the problems mentioned in the background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A watch case polishing and clamping mechanism comprises a bracket, a first hollow rotating platform, a connecting seat, a second hollow rotating platform, a connecting frame, an elastic inner support chuck, an elastic inner support assembly and a cylinder; the first hollow rotating platform is installed on the bracket and the power output end is connected to the connecting seat, which is used to control the rotation of the connecting seat around the Y axis; the second hollow rotating platform is installed on the left side of the connecting seat and the power output end is connected to the elastic inner support chuck, which is used to control the rotation of the elastic inner support chuck around the X axis; the connecting frame is fixed to the right side of the connecting frame; the elastic inner support assembly comprises a pull rod, a spring and a limit nut; the pull rod passes through the connecting frame, the connecting seat, the second hollow rotating platform and the elastic inner support chuck in sequence from the right side of the connecting frame; the pull rod is rotatably connected to the connecting frame; the spring and the limit nut are sequentially installed on the right end of the pull rod; the cylinder is fixed on the connecting frame and is located on the right side of the pull rod; the cylinder is used to touch the pull rod to move to the left.
[0006] Further description of the utility model: a bearing and a bearing limit block are installed on the connecting frame; the pull rod is connected to the bearing; and two ends of the spring respectively contact the bearing and the limit nut.
[0007] Further description of the utility model, the elastic inner support chuck is provided with four inner support blocks; the outer side of each inner support block is provided with a positioning protrusion protruding to the left.
[0008] The beneficial effects of the utility model are:
[0009] The present invention can control the swinging angle of the watch case around the Y-axis through the first hollow rotating platform, and control the rotation direction of the watch case around the X-axis through the second hollow rotating platform, so that the position of the watch case can be controlled at multiple angles, which is convenient for one-time clamping to complete the processing. The elastic inner support component is used to control the elastic inner support chuck to open and tighten the watch case. The present invention uses a spring to push the limit nut to the right to control the pull rod to move to the right. The pull rod opens the elastic inner support chuck to tighten the watch case, which can provide a stable pre-stress and avoid damage to the watch case due to excessive opening force. The cylinder touches the pull rod to the left to loosen the watch case for removal and placement, which is convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings:
[0014] like Figure 1-3As shown, a watch case grinding and clamping mechanism includes a bracket 21, a first hollow rotating platform 22, a connecting seat 23, a second hollow rotating platform 24, a connecting frame 25, an elastic inner support chuck 26, an elastic inner support assembly 27 and a cylinder 28; the first hollow rotating platform 22 is installed on the bracket 21 and the power output end is connected to the connecting seat 23, so as to control the connection seat 23 to rotate around the Y axis; the second hollow rotating platform 24 is installed on the left side of the connecting seat 23 and the power output end is connected to the elastic inner support chuck 26, so as to control the elastic inner support chuck 26 to rotate around the X axis; the connecting frame 25 is fixed on the right side of the connecting seat 23; the elastic inner support assembly 27 includes a pull rod 271, a spring 272 and a limit nut 273; the pull rod 271 is sequentially passed through the connecting frame 25, the connecting seat 23, the second hollow rotating platform 24 and the elastic inner support chuck 26 from the right side of the connecting frame 25; the pull rod 271 is rotatably connected to the connecting frame 25 The spring 272 and the limit nut 273 are installed on the right end of the pull rod 271 in sequence; the cylinder 28 is fixed on the connecting frame 25 and is located on the right side of the pull rod 271; the cylinder 28 is used to touch the pull rod 271 to move to the left; the first hollow rotating platform 22 can control the swing control angle of the watch case around the Y axis, and the second hollow rotating platform 24 can control the rotation control direction of the watch case around the X axis, so that the position of the watch case can be fully controlled, which is convenient for one-time clamping to complete the processing, and the elastic inner support component 27 is used to control the elastic inner support chuck 26 to open and tighten the watch case. The spring 272 is used to control the limit nut 273 to touch the right to control the pull rod 271 to move to the right. The pull rod 271 opens the elastic inner support chuck 26 to tighten the watch case, which can provide a stable pre-pressure degree to avoid damage to the watch case due to excessive opening force.
