[0015] The accompanying drawings, which form a part of the present application, are intended to provide further understanding of the present application, and the illustrative embodiments of the present application and their descriptions are used to explain the present application, and do not constitute improper limitations on the present application. In the drawings:

[0016] Figure 1 Fig. 1 shows a structural schematic diagram of an embodiment of the tool magazine structure according to the present application.

[0017] In the above drawings, the following reference signs are used:

[0018] 1, driving component; 11, driving component body; 12, driving shaft; 13, motor; 14, speed reducer; 2, tool disc; 3, elastic member; 4, gland; 5, detection component; 6, mounting frame. DETAILED DESCRIPTION

[0019] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] As shown in Figure 1 The present application provides a tool magazine structure, comprising: a driving component 1, comprising a driving component body 11 and a driving shaft 12; a tool disc 2, sleeved on the driving shaft 12 and movably arranged along the rotation axis of the driving shaft 12; an elastic member 3, located on the side of the tool disc 2 close to the driving component body 11 and sleeved on the driving shaft 12; and a gland 4, located on the side of the tool disc 2 away from the elastic member 3 and detachably connected with the driving shaft 12.

[0021] In this way, the tool magazine structure of the present application solves the problem that the umbrella-shaped tool magazine used by the vertical machining center in the prior art cannot correctly loosen or tighten the tool due to Z-axis positioning error or spindle failure, which leads to pulling and pressing the tool disc and further damages the tool magazine component and even the spindle, by providing the elastic member 3 and the gland 4 and other structures on the existing umbrella-shaped tool magazine structure. The vertical machining center using the umbrella-shaped tool magazine can maximize the protection of the tool magazine component and the spindle when the tool disc is pulled and pressed after various tool taking failures occur, avoiding damage caused by maintenance and replacement, greatly improving the survival probability after the failure of the related equipment, and enabling the equipment parts affected by the failure to continue to be used with no damage or minimal damage.

[0022] The driving shaft 12 is provided with a structure for circumferentially limiting the tool disc 2, and the center hole of the tool disc 2 has a hole diameter slightly larger than the outer diameter of the driving shaft 12, so as to leave a space for the tool disc 2 to move up and down and tilt.

[0023] As shown in Figure 1 The tool magazine structure further comprises a position detection component 5, and a detection probe of the position detection component 5 is arranged towards the driving shaft 12, so as to detect the position state of the tool disc 2 on the driving shaft 12, and to determine whether to trigger an emergency stop operation according to the detection result.

[0024] The position detection component 5 is a proximity sensor.

[0025] When the tool disc 2 is pulled and pressed, the elastic member 3 below the tool disc 2 can play a buffering role to a certain extent, buffering the force caused by being pulled and pressed, and also giving the tool disc 2 a certain tilt angle. When the force on the tool disc 2 is too large and the elastic member 3 approaches the bottom and cannot continue to provide buffering, the corresponding tilt angle of the tool disc 2 will also become larger. When the tilt angle reaches a certain angle, the position detection component 5 will be triggered, and the system will automatically trigger an emergency stop operation after receiving the signal from the position detection component 5, so as to prevent further damage to the tool magazine component and the spindle.

[0026] As shown in Figure 1As shown, the tool magazine structure further comprises a mounting frame 6 arranged on one side of the driving component 1 for mounting the position detection component 5.

[0027] Specifically, the mounting frame 6 is processed by sheet metal, and mounting holes for mounting the position detection component 5 are arranged on the mounting frame 6.

[0028] Optionally, the mounting frame 6 is a tool magazine sheet metal.

[0029] Preferably, the side of the tool disc 2 close to the gland 4 is provided with a groove part for gap cooperation with the outer peripheral surface of the gland 4, so as to position the tool disc 2.

[0030] The groove part is an annular groove for plug-in cooperation with the lower end of the gland 4.

[0032] As shown in the figure, Figure 1 The driving component body 11 further comprises a speed reducer 14, the speed reducer 14 comprises a speed reducer body and a speed reducer shaft, the driving component body 11 comprises the speed reducer body, and the driving shaft 12 comprises the speed reducer shaft, the speed reducer body is connected with the motor body, the speed reducer shaft is connected with the motor shaft, and the tool disc 2 is located on the side of the speed reducer body away from the motor body and is installed on the speed reducer shaft.

[0033] The elastic member 3 of the present application is a compression spring; and / or the gland 4 is threadedly connected with the driving shaft 12.

[0034] The present application further provides a machining center comprising the tool magazine structure.

[0035] The installation process of the tool magazine structure of the present application is as follows:

[0036] (1) If a new tool magazine is assembled, first, the support structure of the tool magazine is fixed, then the motor is installed, then the speed reducer is installed, then the elastic member 3 is sleeved on the speed reducer shaft, then the tool disc 2 is sleeved on the speed reducer shaft, at this time, a vertical downward force is needed to be given to the tool disc 2 by means of a tool to compress the elastic member 3, so as to install the gland 4; finally, the proximity position detection component 5 is installed on the mounting frame 6 with the hole position punched in advance, the line of the proximity position detection component 5 is connected, and the related parameters are set.

[0037] (2) If a product tool magazine is transformed, the tool magazine sheet metal, the tool disc, the speed reducer and the motor are directly disassembled, the hole position of the proximity position detection component 5 is punched on the tool magazine sheet metal, and then the steps in (1) are installed.
