Problems solved by technology

[0003] When the existing precision CNC machining center performs automatic tool change, it replaces the tool on the processing end with the existing tool in the tool magazine according to the different processing types, but with the increase of processing types and the processing process damaged, the tools in the tool magazine also need to be replaced. The existing automatic tool changer is not convenient for the purpose of replacing the tool magazine. Manual tool change is time-consuming and laborious, which reduces the applicability of the tool changer. Therefore, we need to propose A precision numerical control machining center and its automatic tool changing device

Embodiment 1

[0025] see Figure 1-4 , the present invention provides a technical solution: a precision CNC machining center and its automatic tool changer, including a CNC machining center body 1 and an automatic tool changer 2, the automatic tool changer 2 includes a tool magazine 3 and a tool magazine switching device 4 , the tool magazine 3 is fixedly installed inside the CNC machining center body 1, and the tool magazine switching device 4 is fixedly installed on one side of the tool magazine 3;

[0026] The interior of the CNC machining center body 1 and the lower part of the tool magazine 3 are fixedly installed with a connection assembly 5, the connection assembly 5 includes a sealing mechanism 6, and the sealing mechanism 6 is fixedly installed inside the CNC machining center body 1, and the sealing mechanism 6 is switched close to the tool magazine A slide bar 7 is fixedly installed on the bottom of one side of the device 4, and one end of the slide bar 7 runs through the CNC mach...

Embodiment 2

[0032] see Figure 1-4The difference between this embodiment 2 and embodiment 1 is that the sealing mechanism 6 includes a hollow plate 8, the hollow plate 8 is fixedly installed inside the CNC machining center body 1, and one side of the hollow plate 8 is bolted to one end of the slide bar 7 Then, the top of the hollow plate 8 is slidingly plugged with a sealing plate 9, the top of the sealing plate 9 is attached to the surface of the tool magazine 3, and the side of the hollow plate 8 away from the tool magazine 3 is fixedly installed with a protective box 10, and the protective box 10 The inner cavity is fixed with a second motor 11, the output shaft of the second motor 11 is fixed with a first gear 12, one side of the first gear 12 is meshed with a second gear 13, and the inner ring of the second gear 13 is fixed with a rotating shaft , and the front and rear ends of the rotating shaft are rotatably connected with the inner wall of the protective box 10, the front of the s...

Embodiment 3

[0035] see Figure 1-4 , the difference between this embodiment 3 and embodiment 1 and embodiment 2 is:

[0036] One end of the slide bar 7 extends to the inner cavity of the box body 15 and is bolted to the inside of the box body 15. The bottom of the support plate 20 is fixedly equipped with a sliding sleeve 25, which is slidably socketed on the surface of the slide bar 7; One side of 15 and one side of the CNC machining center body 1 are provided with a through groove matching the slide bar 7, the tool holder 21 and the support plate 20, and the slide bar 7 extends to the inner cavity of the box body 15 through the through slot;

[0037] When the support plate 20 moves, it drives the sliding sleeve 25 to move on the surface of the slide bar 7. By setting the slide bar 7 and the sliding sleeve 25, it is used to support the support plate 20 and facilitate the movement of the support plate 20 to keep the support plate 20 fixed. Stationary;

[0038] The top of the sealing pla...

Abstract

The invention discloses an automatic tool changing device of a precision numerical control machining center, comprising a tool magazine switching device including a box body and a driving mechanism, the driving mechanism is fixedly installed on one side of the top of the box body, and the box body is far away from the side of the driving mechanism One side is bolted to one side of the CNC machining center body, and a screw is installed on the top of the inner cavity of the box. One end of the screw rotates through the box and extends to the inside of the drive mechanism to be connected with the drive mechanism. The screw The surface of the screw sleeve is threaded with a screw sleeve, the bottom of the screw sleeve is fixedly installed with a connecting rod, the bottom of the connecting rod is fixedly installed with a support plate, and the top of the support plate is fixedly installed with a knife compatible with the tool magazine. seat. In the present invention, the drive mechanism is provided to provide moving power for the tool holder. After the tool holder moves to the bottom of the tool magazine, the tool magazine replaces the original knives with the ones on the tool holder, so as to achieve the convenience of matching the knives in the tool magazine. The purpose of the update is to improve the efficiency of tool changing.

Description

technical field [0001] The invention relates to the technical field of precision numerical control machining centers, in particular to a precision numerical control machining center and an automatic tool changing device thereof. Background technique [0002] The machining center is developed from the CNC milling machine. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the automatic tool changer can be used in one clamping. Change the processing tool on the spindle to realize multiple processing functions. The CNC machining center is a high-efficiency automatic machine tool suitable for processing complex parts composed of mechanical equipment and CNC system. The CNC machining center is currently the world's highest output and most widely used One of the CNC machine tools, it has strong comprehensive processing ability, and ca...
