[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0024] like Figures 1 to 6 As shown, an internal support type quick clamping fixture in one embodiment of the utility model includes a workbench 11, a servo motor 12 is fixedly connected to the workbench 11, and a fixed plate 13 is fixedly connected to the servo motor 12. A mounting frame 2 is fixedly connected to the fixed plate 13, and the mounting frame 2 includes a first mounting plate 21, a second mounting plate 22 and a fixed plate 23. A cylinder 31 is fixedly connected to the first mounting plate 21, a punch 41 is fixedly connected to the cylinder 31, a chuck 51 is fixedly connected to the punch 41, and a watch case 61 is clamped at the front end of the chuck 51.
[0025] Specifically, the fixing plate 13 is fixedly connected to the output shaft of the servo motor 12, the second mounting plate 22 is fixedly connected to the fixing plate 13, and the first mounting plate 21, the second mounting plate 22 and the fixing plate 23 are respectively provided with matching third fixing holes 214, and bolts can be threadedly connected between the third fixing holes 214 for easy installation and removal. A through hole 211 matching the punch 41 is provided in the first mounting plate 21, and the cylinder 31 is fixedly connected to the inner side of the first mounting plate 21 by threaded connection. The punch 41 passes through the through hole 211, and can play a supporting and fixing role on the watch case 61 through the clamp 51.
[0026] The clamping head 51 adopts an inner support method to clamp the watch case 61 , thereby increasing the clamping efficiency of the watch case 61 .
[0027] The servo motor 12 is locked on the workbench 11. The servo motor 12 rotates, driving the chuck 51 to rotate, and can realize the curved surface processing of the watch case 61. The first mounting plate 21 can be provided with multiple mounting positions of the chuck 51, so that multiple watch cases 61 can be clamped at one time.
[0028] The chuck 51 includes a fixing seat 52, a plurality of fourth fixing holes 521 are formed in the fixing seat 52, and a first fixing hole 212 matching the fourth fixing hole 521 is formed on the first mounting plate 21. Bolts can be threadedly connected between the first fixing hole 212 and the fourth fixing hole 521 to firmly fix the chuck 51 on the first mounting plate 21, so that the chuck 51 can rotate more stably with the servo motor 12.
[0029] Furthermore, the punch 41 is fixedly connected to the cylinder shaft of the cylinder 31, and the punch 41 can be fixed to the cylinder shaft of the cylinder 31 by threaded connection, which is convenient for installation and removal. A conical step is provided at the front end of the punch 41, and a conical hole matching the conical step is provided in the chuck 51. The angle of the conical step is smaller than that of the conical hole.
[0030] Specifically, the cylinder 31 can drive the punch 41 to move forward. As the punch 41 goes deeper, it can be more firmly clamped in the tapered hole in the chuck 51, thereby increasing the stability between the punch 41 and the chuck 51.
[0031] Furthermore, the front end of the chuck 51 is divided into four pieces, each of which has a gap. As the punch 41 continues to penetrate into the tapered hole, the front end of the chuck 51 divided into four pieces can be stretched open, thereby firmly supporting the watch case 61 located outside the chuck 51, thereby increasing the stability between the watch case 61 and the chuck 51.
[0032] Furthermore, a case limit block bracket 71 is sleeved on the chuck 51, and a group of case limit blocks 72 matching the case 61 are fixedly connected to the case limit block bracket 71, and the case 61 is located between the group of case limit blocks 72. The case limit block bracket 71 is located at the rear of the case 61, and the case limit block bracket 71 and the case limit block 72 can limit the case 61, so as to prevent the case 61 from being offset on the chuck 51 when the case 61 is processed.
[0033] Further, a plurality of fifth fixing holes 711 are provided on the case limit block bracket 71, and a second fixing hole 213 matching the fifth fixing hole 711 is provided on the first mounting plate 21. A sixth fixing hole 712 is provided on the case limit block bracket 71, and a seventh fixing hole 721 matching the sixth fixing hole 712 is provided in the case limit block 72. The case limit block bracket 71 is conveniently threadedly connected to the first mounting plate 21, and the case limit block 72 is threadedly connected to the case limit block bracket 71, so as to facilitate installation and disassembly.
[0034] Furthermore, there is a gap between the case limit block bracket 71 and the chuck 51, and a plurality of support columns 713 are fixedly connected to the case limit block bracket 71. The case limit block bracket 71 does not affect the opening of the chuck 51. The support columns 713 can abut against the rear side of the case 61, and the case limit block 72 can abut against the upper and lower sides of the case 61 to increase the stability of the case 61.
[0035] When using, refer to Figure 1 to Figure 6 As shown, the case limit block bracket 71 is installed on the chuck 51, and the case limit block bracket 71 and the chuck 51 are fixed on the outside of the first mounting plate 21. The case 61 is clamped on the front end of the chuck 51, and the inner side of the case 61 can be supported by the support column 713. A set of case limit blocks 72 are respectively installed on the upper and lower sides of the case 61 to support the upper and lower sides of the case 61. The punch 41 is fixed on the cylinder 31, and the cylinder 31 is threadedly connected to the inner side of the first mounting plate 21, so that the punch 41 passes through the first mounting plate 21. Start the cylinder 31, and the cylinder 31 drives the punch 41 to move forward, extend into the tapered hole in the chuck 51, and the front end of the chuck 51 divided into four pieces is stretched open, thereby firmly supporting the case 61. The case 61 can be driven to rotate by the servo motor 12 to process the case 61.
[0036] Compared with the prior art, the utility model provides an internally supported quick-clamping fixture, which can increase the stability of clamping watch case products, has high clamping efficiency, fast clamping speed, greatly saves processing time, and improves processing efficiency.
