Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool workpiece loading and unloading fixtures, and particularly relates to a longitudinal air path docking type machine tool loading and unloading tool holder fixture. Background Technology

[0002] When using machine tools, solving the technical problem of automatic workpiece loading and unloading is of great significance to ensuring the continuity of workpiece processing.

[0003] In related technologies, an in-machine clamping device for thin workpieces with a rotary chuck is disclosed, comprising: an air source base, an adapter plate, and a rotary chuck. The air source base is annular and installed below the spindle seat, moving synchronously with the spindle seat. The air source base is connected to either a pressurized air source or a vacuum air source to provide these two sources. The adapter plate is used to achieve both the physical structural connection and the air circuit connection between the tool holder assembly and the rotary cylinder. When loading the tool into the tool magazine, the combination of the adapter plate and the rotary chuck is inserted as a whole into the tool magazine. Using the structure of this related technology, the connection between the adapter plate and the air source base includes both air circuit connection and mechanical connection. To ensure the reliability of both the air circuit connection and the mechanical connection, the length of the adapter plate matches the diameter of the air source base. The relatively long length of the adapter plate results in a large overall longitudinal dimension after the combination of the adapter plate and the rotary chuck. In practical applications, this method of inserting the entire assembly into the tool magazine significantly affects the compatibility of the tool magazine.

[0004] The shortcoming of the related technology is that, in practical applications, when the adapter plate and rotary chuck chuck assembly is loaded onto the machine tool magazine, if the distance between the magazine support and the tool holder is too small, the adapter plate and rotary chuck chuck assembly will easily interfere with the magazine support due to their large overall length dimension, resulting in the adapter plate not being able to enter the magazine normally.

[0005] Therefore, it is necessary to provide a new longitudinal air-path docking type machine tool loading and unloading tool holder fixture to solve the above-mentioned technical problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] Based on this, the present invention provides a longitudinal air-path docking type machine tool loading and unloading tool holder fixture, which aims to solve the technical problem that the combination of the adapter plate and the rotary suction cup clamping head in the existing in-machine clamping equipment is too large and easily interferes with the tool magazine support.

[0049] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0050] The following is in conjunction with the appendix Figure 1-7 The present invention provides a further description of the longitudinal air path docking type machine tool loading and unloading tool holder 100.

[0051] This utility model discloses a longitudinal air-path docking type machine tool loading and unloading tool holder 100. The longitudinal air-path docking type machine tool loading and unloading tool holder 100 is applied to a machine tool, which includes a spindle seat and a machine tool spindle mounted on the spindle seat. A recessed tool holder interface is provided below the machine tool spindle. The longitudinal air-path docking type machine tool loading and unloading tool holder 100 includes a fixed air supply module 1 and a movable tool holder gripper module 2. The fixed air supply module 1 includes a mounting ring plate 11, a mounting base 12, and a right-angle air source base 13. One side of the mounting ring plate 11 is mounted on the spindle seat, and the mounting base 12 is fixedly mounted on the lower part of the other side of the mounting ring plate 11. The right-angle air source base 13 is fixedly mounted on the lower part of the mounting base 12. The movable tool holder gripper module 2 includes a tool holder body 21 and a cylinder end air distribution block 22, which are fixedly connected from top to bottom. The pneumatic rotary cylinder 23 with a suction cup 231 at the end has an air seat end air distribution block 24 on one side of the cylinder body end air distribution block 22. The lower part of the right-angle air source seat 13 has an air passage connection interface 1321, and the upper part of the air seat end air distribution block 24 has an air passage lower connection interface 241. The air seat end air distribution block 24 has a second air passage that communicates with the air passage lower connection interface 241. The cylinder body end air distribution block 22 has a third air passage that communicates with the second air passage and the interior of the pneumatic rotary cylinder 23. The longitudinal air passage docking type machine tool loading and unloading tool holder 100 includes a spindle-connected state. When the longitudinal air passage docking type machine tool loading and unloading tool holder 100 is in the spindle-connected state, the upper part of the tool holder body 21 is installed in the tool holder interface, the air seat end air distribution block 24 is located at the lower part of the right-angle air source seat 13, and the air passage connection interface 1321 communicates with the air passage lower connection interface 241.

[0052] In this embodiment, the longitudinal air path docking type machine tool loading and unloading tool holder 100 is used such that the fixed air supply module 1 is fixedly installed on the spindle seat, which is used to connect to the air source and, after docking with the movable tool holder gripper module 2, can provide an air source to the movable tool holder gripper module 2.

[0053] The movable tool holder gripper module 2, driven by the tool magazine gripper 200, first moves to below the tool holder interface, then moves upward, so that the upper part of the tool holder body 21 is installed inside the tool holder interface. The air path interface 1321 is connected to the lower air path interface 241, so that the longitudinal air path docking type machine tool loading and unloading tool holder fixture 100 is in the spindle-connected state. The longitudinal air path docking type machine tool loading and unloading tool holder fixture 100 of this utility model can be used to pick up the workpiece 300 and can drive the workpiece 300 to rotate to the required machining angle; or it can be rotated first to adapt to the angle of the workpiece 300 to be loaded, and then the workpiece 300 can be picked up; finally, the loading and unloading of the workpiece 300 is realized.

[0054] When the movable tool holder gripper module 2 needs to be placed into the tool magazine, the tool magazine gripper 200 clamps the tool holder body 21 and moves downward, causing the movable tool holder gripper module 2 to move downward as a whole, the tool holder body 21 to disengage from the tool holder interface, and the air path interface 1321 and the air path lower interface 241 to disconnect.

[0055] In the longitudinal air path docking type machine tool loading and unloading tool holder 100 of this utility model, the movable tool holder gripper module 2 moves longitudinally to achieve docking or disengagement. Since the air path docking process is completed in the longitudinal direction (up and down direction), it is called "longitudinal air path docking type".

[0056] The movable tool holder gripper module 2 needs to enter the tool magazine. The tool holder body 21, cylinder end air distribution block 22, and pneumatic rotary cylinder 23 are arranged from top to bottom, which does not increase the horizontal dimension of the movable tool holder gripper module 2. Although the air seat end air distribution block 24 increases the overall horizontal dimension of the movable tool holder gripper module 2, the increase in the horizontal dimension of the air seat end air distribution block 24 is smaller than that of the traditional design because the air seat end air distribution block 24 is located on one side of the cylinder end air distribution block 22, and the air seat end air distribution block 24 only needs to complete the air path connection between the right-angle air source seat 13 and the cylinder end air distribution block 22. The top of the air seat end air distribution block 24 connects with the lower part of the right-angle air source seat 13, and the side of the right-angle air source seat 13 connects with the cylinder end air distribution block 22.

[0057] Compared with existing technologies, the longitudinal air-path docking type machine tool loading and unloading tool holder fixture 100 of this utility model has a smaller overall horizontal dimension of the movable tool holder gripper module 2, which can be adapted to tool magazines in small spaces and avoids interference with the tool magazine support. This allows the longitudinal air-path docking type machine tool loading and unloading tool holder fixture 100 of this utility model to be adapted to more types of machine tools.

[0058] Furthermore, this invention retains the longitudinal air path connection form, eliminating the need for additional air path connection cylinders or other air path connection devices. It only relies on the existing tool magazine grippers required by existing machine tools to achieve the switching of the movable tool holder gripper module 2 between the spindle-connected state and the tool magazine-retracted state. The structure is simple, practical, and low-cost.

[0059] According to a specific embodiment of the present invention, the mounting ring plate 11 includes a connecting clamp 111 and a connecting plate 112 fixed to one side of the connecting clamp 111. The connecting clamp 111 is fixedly sleeved on the lower part of the spindle seat. The side of the connecting clamp 111 away from the connecting plate 112 is provided with an opening 113, and a locking screw 14 is connected to the opening 113. The upper part of the mounting base 12 is fixedly connected to the lower part of the connecting plate 112.

[0060] In this embodiment, during installation, the connecting clamp 111 is aligned with the spindle seat and inserted from bottom to top, then tightened using the locking screw 14 to fix the mounting ring plate 11 to the lower part of the spindle seat. Installation is simple and convenient. The connecting plate 112 is used to connect with the mounting base 12, ultimately achieving a centralized air supply on one side of the spindle seat. This helps to reduce the lateral dimension of the air path connection component in the movable tool holder gripper module 2, avoiding interference and facilitating the smooth loading of the movable tool holder gripper module 2 into the machine tool magazine.

[0061] According to a specific embodiment of the present invention, the upper part of the mounting base 12 has a Y-shaped groove 121, the connecting plate 112 is provided with a first connecting hole 1121, and the fixed air supply module 1 also includes a first connecting screw 15 that passes through the Y-shaped groove 121 and extends into the first connecting hole 1121.

[0062] In this embodiment, this structure allows for flexible adjustment of the mounting base 12 in the Y direction after the mounting ring plate 11 is fixed, thereby improving installation accuracy.

[0063] According to a specific embodiment of this utility model, the right-angle air source base 13 includes a horizontal connecting plate 131 and a vertical air plate 132 that together form a right-angle plate shape. The horizontal connecting plate 131 is provided with an X-shaped waist-shaped hole 1311 that passes through it. The mounting base 12 is provided with a second connecting hole at its lower part. The fixed air supply module 1 also includes a second connecting screw 16 that passes through the X-shaped waist-shaped groove and extends into the second connecting hole. The air path interface 1321 is located at the lower part of the vertical air plate 132. The vertical air plate 132 is provided with an air source inlet 1322 on the side near the mounting base 12. The vertical air plate 132 is also provided with a first air path that connects the air source inlet 1322 and the air path interface 1321.

[0064] In this embodiment, the structure allows for flexible adjustment of the right-angle air source seat 13 in the X-direction, improving installation accuracy. The X-direction oblong hole 1311 and the Y-direction oblong groove 121 work together to adjust the position of the right-angle air source seat 13 in the X and Y directions. Adjusting the mounting height of the mounting ring plate 11 on the spindle seat adjusts the position of the right-angle air source seat 13 in the Z-direction. Thus, the structure of this embodiment allows for flexible adjustment of the right-angle air source seat 13 in the X, Y, and Z directions, ensuring installation accuracy. This ensures that after the movable tool holder gripper module 2 is connected to the fixed air supply module 1, the upper part of the tool holder body 21 is precisely installed in the tool holder interface, and the air path interface 1321 and the lower air path interface 241 are precisely aligned vertically.

[0065] Furthermore, the right-angle air source base 13 is entirely right-angled, and the air source port 1322 is located on the side of the vertical air plate 132 near the mounting base 12. With this structure, during use, the air pipe connector 17 of the air source port 1322 can be arranged below the horizontal connecting plate 112, which avoids the connector protruding and provides sufficient space for the arrangement of the second connecting screw 16. The lower part of the vertical air plate 132 is the lowest part of the right-angle air source base 13, which helps to ensure smooth connection with the air distribution block 24 at the lower air base end.

[0066] According to a specific embodiment of this utility model, the upper part of the gas seat end gas distribution block 24 is provided with a recessed docking part mounting hole 242, and one side of the gas seat end gas distribution block 24 is provided with a stroke limiting groove (not shown in the figure) communicating with the docking part mounting hole 242; the movable tool holder gripper module 2 also includes a quick docking unit 25, which includes: a compression spring 251, a telescopic pin 252 and a limiting screw 253; the compression spring 251 is disposed in the docking part mounting hole 242, the telescopic pin 252 is slidably connected to the docking part mounting hole 242, and the lower part of the telescopic pin 252 is connected to the compression spring 251. The upper part of the telescopic pin 252 is a tapered connector 2521. The connector 2521 extends out of the mating part mounting hole 242. One end of the limiting screw 253 is fixed to the telescopic pin 252, and the other end of the limiting screw 253 extends into the stroke limiting groove (not shown in the figure). The lower part of the vertical air plate 132 is provided with a recessed alignment mating groove 1327. The shape of the alignment mating groove 1327 matches the shape of the connector 2521. When the longitudinal air path docking type machine tool loading and unloading tool holder 100 is in the spindle connected state, the connector 2521 is inserted into the alignment mating groove 1327.

[0067] In this embodiment, the compression spring 251 and the telescopic pin 252 are combined to form a telescopic spring pin structure. When the air circuit docking cylinder docks with the pneumatic actuator to be driven, a docking groove matching the shape of the docking joint 2521 is pre-set at the corresponding position of the pneumatic actuator to be driven. When the air circuit docking is performed, the docking joint 2521 is aligned with the docking groove 1327, which can quickly realize the rapid docking of the air circuit docking cylinder and the pneumatic actuator to be driven.

[0068] In this embodiment, a travel limiting groove is provided on the air distribution block 24 at the air seat end, and the limiting screw 253 is fixed to the telescopic pin 252 to realize the travel limit of the telescopic pin 252.

[0069] It should be noted that, in addition to the structure described above, the following structure can also be used to achieve the travel limit of the telescopic pin 252: a recessed telescopic limit groove 2522 is provided on the telescopic pin 252; a limit screw 253 hole communicating with the mounting hole 242 of the docking part is provided on one side of the air distribution block 24 at the air seat end. One end of the limit screw 253 is fixedly installed in the limit screw 253 hole, and the other end of the limit screw 253 extends into the telescopic limit groove 2522 on the telescopic pin 252. When the telescopic pin 252 moves up and down, it stops when it hits the upper and lower side walls of the telescopic limit groove 2522, thus achieving travel limit. This structure avoids external sliding parts and provides higher safety.

[0070] According to a specific embodiment of the present invention, the lower air passage interface 241 is embedded with a protruding rubber air passage 26, and the groove of the upper air passage interface 1321 is provided with a recessed air passage docking groove 13211. The shape of the air passage docking groove 13211 matches the shape of the rubber air passage 26. When the longitudinal air passage docking type machine tool loading and unloading tool holder 100 is in the spindle-connected state, the rubber air passage 26 abuts against the air passage docking groove 13211.
