Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] See Figure 1-4 This embodiment relates to a tool switching assembly 1 for a dual-spindle dual-turret CNC machine tool, including a dual-spindle dual-turret CNC machine tool body 100 and multiple sets of tool switching assemblies 1 installed in several mounting slots 1011 provided on the turret 101. The tool switching assembly 1 includes a fixed seat 11 detachably installed in the mounting slots 1011 on the turret 101 and a connecting seat 12 slidably provided on it. The connecting seat 12 is provided with a second mounting slot 123 for sliding of the tool 10. The connecting seat 12 is provided with multiple sets of first locking members 121 and second locking members 122 for locking the positions of the connecting seat 12 and the tool 10.

[0020] Specifically in this embodiment, such as Figure 1 The diagram shows the overall structure and corresponding connection method of the main body 100 of this dual-spindle dual-turret CNC machine tool and its tool switching assembly 1, combined with... Figure 2 and Figure 3 The dual-spindle, dual-turret CNC machine tool body 100 shown adopts the common dual-spindle, dual-turret CNC machine tool 101 structure in the prior art. Driven by multiple sets of drive components 103 using synchronous belts 1031 and ball screws 1032, it can perform machining processes such as cutting on parts held by the chuck 102 through the rotation and directional movement of the chuck 102 and turret 101, as well as the switching of tools 10 on the turret 101. Specifically, in the initial stage of use, it can be combined with... Figure 4The process of installing multiple sets of tool switching components 1 in several mounting slots 1011 provided on the turret 101 is shown. The fixing base 11 can be detachably installed in the mounting slots 1011 on the turret 101 via bolt connections. At the same time, the second mounting slot 123 provided on the connecting base 12 can be used to place the tool 10 structure. Combined with the second locking member 122, which is set and rotated on the connecting base 12 at the corresponding position using a bolt connection structure, the tool 10 placed in the second mounting slot 123 can be locked in the corresponding position. Then, the connecting base 12 can be slidably connected to the matching slide rail 110 provided on the fixing base 11 via the sliding groove 120 provided on it. After the position adjustment is completed, the position of the connecting base 12 on the fixing base 11 can be locked by the first locking member 121, which is set and rotated on the connecting base 12 at the corresponding position using a bolt connection structure. This process is repeated to achieve the above operation. The process of installing multiple sets of tool switching components 1 and their connecting seats 12 with different models of compatible tools 10 in corresponding positions in several mounting slots 1011 on the turret 101. In addition, when the position of the tool 10 on the connecting seat 12 needs to be adjusted, the position of the connecting seat 12 and the tool 10 in the second mounting slot 123 on the slide rail 110 of the fixed seat 11 can be adjusted and locked by rotating the first locking member 121 and the second locking member 122 provided at the corresponding positions of the connecting seat 12. The connecting seat 12 can be directly removed from the fixed seat 11 by the first locking member 121 according to the specific situation of the tool 10. Then, another set of connecting seats 12 and the corresponding model of tool 10 clamped and fixed by the second locking member 122 can be locked on the fixed seat 11 under the action of the first locking member 121, so as to realize the corresponding model switching process of the connecting seat 12 and the tool 10 on it.The overall structure of the tool switching assembly 1 on this dual-spindle dual-turret CNC machine tool and its connection method with the turret 101 allow for the initial and pre-installation of corresponding types of tools 10 in the fixed seat 11 in the mounting slot 1011 of the turret 101 and the second mounting slot 123 on the connecting seat 12 via bolt connections. Simultaneously, combined with the sliding connection between the connecting seat 12 and the fixed seat 11, and the locking mechanisms of the first locking member 121 and the second locking member 122 on the corresponding positions of the connecting seat 12 to the connecting seat 12 and the tools 10 thereon, the first locking member 121 enables a detachable connection of the connecting seat 12 during its sliding motion on the fixed seat 11, further improving the connection efficiency. The connection seat 12 and the tool 10 on it are convenient and quick to switch. In addition, the rotation process of the first locking member 121 and the second locking member 122 on the connection seat 12, and the up and down sliding process of the tool 10 on the fixed seat 11 and the second mounting groove 123 of the connection seat 12, realize the installation, disassembly, replacement, feed position adjustment and corresponding position locking of the tool 10 in the mounting groove 1011 on the turret 101. This further improves the structural diversity and usage flexibility of the tool 10 to be installed and fixed on the turret 101 through this tool switching component 1. The position can be easily adjusted and switched according to the usage of the tool 10 to meet different usage needs.

[0021] The fixed base 11 includes a first base body 111 detachably mounted in the mounting slot 1011 on the turret 101 and a second base body 112 detachably connected to it for sliding of the connecting base 12. Specifically, from Figure 4 and Figure 5 As can be seen, the fixed base 11 with this structure can be detachably connected to the mounting groove 1011 on the turret 101 and the second base 112 on it by means of bolts on the corresponding position of the first base 111 during installation. The connecting base 12 is slidably connected by means of slide rail 110 on the second base 112. Thus, combined with the structure of the first base 111 and the second base 112 in the fixed base 11, the detachability and disassembly flexibility of this tool switching assembly 1 can be further improved, which facilitates the maintenance and replacement of the corresponding base structure.

[0022] A pad 1121 is detachably installed on the wall surface corresponding to the second locking member 122 on the connecting seat 12. The pad 1121 can be detachably connected to the corresponding wall surface of the second seat 112 by means of bolts or adhesive. The addition of the pad 1121 can effectively prevent the second locking member 122 from directly contacting the corresponding wall surface of the second seat 112 when locking the position of the connecting seat 12, thereby effectively reducing the wear on the corresponding wall surface of the second seat 112. Furthermore, the pad 1121 can be made of anti-slip materials such as rubber pads to further increase the friction between it and the second locking member 122, further improving the locking effect and positional stability of the second locking member 122 on the connecting seat 12, and improving the positional stability of the tool 10 on the connecting seat 12, as well as the corresponding effect and usage stability.

[0023] The tool switching assembly 1 also includes a storage box 2 installed on the main body 100 of the dual-spindle dual-turret CNC machine tool for storing the tool switching assembly 1. The storage box 2 includes a box body and a drawer 3 slidably disposed inside. Multiple sets of third locking elements for locking the position of the drawer 3 are rotatably disposed on the box body. The storage box 2 can be installed and fixed in a corresponding position according to the structural configuration of the main body 100 of the dual-spindle dual-turret CNC machine tool. Specifically, the installation process can be carried out by combining the protrusions 21 on both sides of the bottom of the storage box 2, the mounting holes 211 opened on them, and the bolts with matching structures. Figure 1 For example, without affecting the normal cutting process of the turret 101, the storage box 2 is installed and fixed on the base structure of the turret 101. See also... Figure 6 The internal structure of the storage box 2 and the corresponding structure of the drawer 3 that slides on it are designed to store various sizes of tools 10 and multiple sets of tool switching components 1 on the turret 101 in the drawer 3 of the storage box 2. This further improves the functionality of the tool switching component 1 and the speed of installing, removing, and switching the tools 10 in the mounting slot 1011 on the turret 101. In addition, the drawer 3 in the storage box 2 can be locked in position by multiple sets of third locking parts 22 that are rotatably set at the corresponding position of the box body. This effectively prevents the drawer 3 in the storage box 2 from shifting or even slipping during the movement of the turret 101, thus improving applicability and practicality.

[0024] The drawer 3 is slidably mounted inside the box via partition strips 23 provided on the inner wall of the box, and the drawer 3 has multiple sets of partitions 31 arranged in the horizontal and vertical directions to form several receiving slots 32. Figure 6As shown, the storage box 2 has multiple sets of drawers 3 arranged inside, which can further expand the storage capacity. At the same time, according to the usage needs, the tool 10 and the corresponding components such as the connecting seat 12 and the fixing seat 11 in the tool switching assembly 1 can be stored in several receiving slots 32 formed by multiple sets of partitions 31 arranged in the horizontal and vertical directions inside the drawer 3, thereby improving the function and usage flexibility of the storage box 2.

[0025] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
