DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the present application provides a spindle structure for a machining center, which solves the problem that the traditional spindle structure mainly adopts an air-cooling structure for heat dissipation design, but the heat dissipation effect is poor. At the same time, the spindle and the robot arm are generally fixed by a mounting plate and multiple sets of screws. Since some robot arms are idle, the operating space for tools during disassembly and assembly is small, which makes it inconvenient to disassemble and assemble the spindle, thereby making it inconvenient to perform subsequent inspection, maintenance and replacement of the spindle structure.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a spindle structure for a machining center. Figure 1-3 As shown, it includes a tool-changing spindle body 1, a water-cooling shell 2 is fixedly connected to the outer side of the tool-changing spindle body 1, and a positioning plate 3 is fixedly connected to the water-cooling shell 2;

[0027] The positioning plate 3 is fixedly connected with a plug-in column 4, and the top of the positioning plate 3 is movably connected with a split bracket, which includes:

[0028] A mechanical arm mounting plate 5 is disposed above the positioning plate 3 and mounted with the mechanical arm;

[0029] The sleeve 6 is arranged at the bottom of the robot arm mounting plate 5; the plug-in column 4 is movably connected to the inside of the sleeve 6;

[0030] The locking pin 7 is movably inserted into the sleeve 6 and the plug-in column 4.

[0031] Furthermore, a guide rod 701 is fixedly connected to the side wall of the sleeve 6, a slider 702 is slidably connected to the guide rod 701, and the locking pin 7 is fixedly connected to the slider 702. The guide rod 701 is provided to provide support and limitation for the slider 702, and the slider 702 is provided to provide support and limitation for the locking pin 7, so that the locking pin 7 is stably stressed, and when the locking pin 7 is clamped in the sleeve 6 and the plug-in column 4, the plug-in is stable and not easy to loosen or come off.

[0032] Furthermore, a vertical plate 704 is fixedly connected to the robot arm mounting plate 5, and a double-threaded screw 705 is rotatably connected to the vertical plate 704;

[0033] An adjusting arm 703 is fixedly connected to the slider 702, and the adjusting arm 703 is threadedly connected to the double-threaded screw 705. The vertical plate 704 provides support and limitation for the double-threaded screw 705. With the design of the adjusting arm 703, when the double-threaded screw 705 rotates, the adjusting arm 703 and the slider 702 are driven to adjust their positions. Therefore, the position of the locking pin 7 is easy to adjust, thereby making it easy to lock or unlock the sleeve 6 and the plug-in column 4, thereby ensuring that the positioning plate 3 and the split bracket are easy to disassemble and assemble.

[0034] It is particularly disclosed that a rotating handle 706 is fixedly connected to the double-threaded screw rod 705, and the rotating handle 706 makes the rotation of the double-threaded screw rod 705 convenient and labor-saving.

[0035] Specifically, a locking hole 401 corresponding to the position of the locking pin 7 is provided on the plug-in column 4 , and the provided locking pin 7 is conveniently inserted into the locking hole 401 to realize the card connection and locking of the plug-in column 4 inside the sleeve 6 .

[0036] Furthermore, a water cooling pipe 201 is fixedly connected to the water cooling shell 2 , and the water cooling pipe 201 is connected to a water pump, so as to conveniently circulate water into the water cooling shell 2 , thereby providing water cooling to the tool changing spindle body 1 .

[0037] The spindle structure for the machining center is provided with a water-cooling shell 2 to provide water-cooling heat dissipation for the tool-changing spindle body 1, thereby ensuring a good heat dissipation effect of the tool-changing spindle body 1. At the same time, through the design of the positioning plate 3 and the split bracket, it is convenient to install the tool-changing spindle body 1 under the robot arm. During subsequent maintenance, it is only necessary to disassemble the tool-changing spindle body 1, the water-cooling shell 2, the positioning plate 3 and the split bracket. The operation space is large, and no additional tools are required. The tool-changing spindle body 1 can be disassembled and maintained or the model can be replaced quickly, thereby facilitating the loading of various spindles.

[0038] When installing the device for the first time, fix the split bracket to the robot arm, specifically fix the robot arm mounting plate 5 to the robot arm with bolts. After fixation, the positioning plate 3 and the split bracket are quickly snapped together to achieve installation of the tool change spindle body 1;

[0039] When the positioning plate 3 and the split bracket are quickly connected, the plug-in column 4 is directly aligned with the inside of the sleeve 6 and inserted, and then the double-threaded screw 705 is rotated. The double-threaded screw 705 drives the two sets of adjustment arms 703 to move, and the adjustment arms 703 drive the slider 702 to slide along the guide rod 701. The slider 702 drives the locking pin 7 to move and insert the locking pin 7 into the locking hole 401, thereby realizing the position connection and locking of the plug-in column 4 and the sleeve 6, and then the position of the positioning plate 3 and the split bracket is fixed, that is, the loading of the tool changing spindle body 1 on the robot arm is realized. When disassembling the tool changing spindle body 1, there is no need to disassemble the split bracket, and the tool changing spindle body 1 can be quickly disassembled, maintained and replaced.
