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 pneumatic connection cylinder, an anti-interference machine tool loading and unloading tool holder fixture, and a multi-station rotary table. 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 anti-interference machine tool loading and unloading fixture to solve the above-mentioned technical problems. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention has the following beneficial effects.

[0021] (I) First, the pneumatic docking cylinder of this invention has a power air path on its piston shaft, and the piston shaft is retractable. After the piston shaft extends, it can dock with the pneumatic actuator to be driven and supply pressurized gas. After the piston shaft retracts, the pneumatic actuator to be driven can be freely adjusted in position. The pneumatic docking cylinder of this invention has a wide range of applications.

[0051] 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.

[0052] The following is in conjunction with the appendix Figure 1-9 Further explanation is given regarding the pneumatic connection cylinder 013, the anti-interference machine tool loading and unloading tool holder 100, and the multi-station rotary table 200 of this utility model.

[0053] Please refer to this carefully. Figure 1-2This utility model discloses a pneumatic docking cylinder 013, including a docking cylinder body 1 and a docking cylinder piston shaft 2 that penetrates the docking cylinder body 1 and is slidably connected to the docking cylinder body 1. The docking cylinder body 1 is provided with a cylinder driving air passage for driving the docking cylinder piston shaft 2 to slide. The docking cylinder piston shaft 2 is provided with a power air passage that penetrates it. The two ends of the power air passage are respectively a gas source end and a workpiece end. The two ends of the docking cylinder piston shaft 2 are respectively a far tool holder end 21 and a near tool holder end 22. The gas source end is located at the far tool holder end 21, and the workpiece end is located at the near tool holder end 22.

[0054] In this embodiment, the connecting end is used to connect with the air path interface of the pneumatic actuator to be driven, and the connecting air source end is used to introduce a power air source to drive the pneumatic actuator. In use, the pneumatic actuator to be driven is located on one side of the air path docking cylinder 013. The pneumatic actuator to be driven includes an air path interface that is directly opposite the connecting end. Pressurized gas is introduced into the pneumatic drive air path, which can drive the piston shaft 2 of the docking cylinder to slide. When the piston shaft 2 of the docking cylinder extends, it allows the connecting end to connect with the air path interface of the pneumatic actuator to be driven. The connecting air source end is used to introduce a power air source to the pneumatic actuator to be driven. When there is no need to supply pressurized gas to the pneumatic actuator to be driven, the piston shaft 2 of the docking cylinder is retracted by using the cylinder to drive the air circuit or the compression spring 32, and the air circuit interface between the workpiece end and the pneumatic actuator to be driven is disconnected. The pneumatic actuator to be driven can be transferred to other required positions as needed. While ensuring that the pneumatic actuator to be driven has a power source, the lateral dimension of the pneumatic actuator to be driven will not be increased, making it easy to accommodate in a device with small space requirements (such as built into a tool magazine).

[0055] Compared with the prior art, the pneumatic docking cylinder 013 of this embodiment, based on the existing cylinder's telescopic function, also provides a power air path on the docking cylinder piston shaft 2, and positions the connecting end of the power air path at one end of the docking cylinder piston shaft 2, so that after the docking cylinder piston shaft 2 extends, it can dock with the pneumatic actuator to be driven and supply pressurized gas. Positioning the air source end at the other end of the docking cylinder piston shaft 2 ensures sufficient space for the air source connector and pipeline, while avoiding interference between the air source connector and pipeline and the connecting end of the connecting workpiece and the pneumatic actuator to be driven. The pneumatic docking cylinder 013 of this invention has wide applications, including providing a power air source for the machine tool movable tool holder gripper module 02, and can also be applied to other scenarios requiring the connection of a pressurized air source to a pneumatic actuator.

[0056] According to a specific embodiment of this utility model, the piston shaft 2 of the docking cylinder includes a docking part mounting hole 23 extending axially therethrough; the air circuit docking cylinder 013 also includes a quick docking unit 3 installed in the docking part mounting hole 23; the quick docking unit 3 includes a spring adjusting screw 31, a compression spring 32 and a pin 33 arranged in a straight line in sequence, the spring adjusting screw 31 is threadedly connected to the docking part mounting hole 23, the two ends of the compression spring 32 abut against the spring adjusting screw 31 and the pin 33 respectively, the pin 33 is slidably connected to the docking part mounting hole 23, and the end of the pin 33 away from the compression spring 32 is provided with a tapered connector 331, the connector 331 protruding from the docking part mounting hole 23.

[0057] In this embodiment, the compression spring 32 and the pin 33 are combined to form a retractable spring pin structure. When the air circuit docking cylinder 013 docks with the pneumatic actuator to be driven, a docking groove 0225 matching the shape of the docking joint 331 is pre-set at the corresponding position of the pneumatic actuator to be driven. When the air circuit docking is performed, the docking joint 331 is aligned with the docking groove 0225, which can quickly realize the rapid docking of the air circuit docking cylinder 013 and the pneumatic actuator to be driven.

[0058] According to a specific embodiment of the present invention, the quick docking unit 3 further includes a first dustproof ring 34 located inside the docking component mounting hole 23 and surrounding the pin shaft 33; and a second dustproof ring 4 is provided between the two ends of the docking cylinder body 1 and the docking cylinder piston shaft 2, respectively.

[0059] When the pneumatic connection cylinder 013 of this utility model is used in a machine tool, the pneumatic connection cylinder 013 needs to be installed below the spindle seat 300. During use, there is a lot of dust around the pneumatic connection cylinder 013, so dust prevention needs to be considered.

[0060] In this embodiment, the first dustproof ring 34 is disposed at the front end of the pin 33, which can effectively prevent external dust from entering the mounting hole 23 of the docking part, prevent the pin 33 from being jammed by dust, and ensure smooth sliding of the pin 33. The second dustproof ring 4 is used for sealing between the piston shaft 2 of the docking cylinder and the cylinder body 1 of the docking cylinder. In specific implementation, the second dustproof ring 4 includes two sealing structures. When the piston shaft 2 of the docking cylinder retracts, the second dustproof ring 4 can scrape off the dust that falls on it, and then retract, which can prevent the piston shaft 2 of the docking cylinder from bringing dust into the cylinder body 1 of the docking cylinder.

[0061] According to a specific embodiment of this utility model, the power air path includes: a forward rotating air path 24, a reverse rotating air path 25, and a vacuum source air path 26; the axial center line of the docking part mounting hole 23 coincides with the axial center line of the docking cylinder piston shaft 2, and the forward rotating air path 24, the reverse rotating air path 25, and the vacuum source air path 26 are evenly arranged around the docking part mounting hole 23.

[0062] It should be noted that in the three air paths—forward rotating air path 24, reverse rotating air path 25, and vacuum air source air path 26—each air path has two ends: the air source connection end and the workpiece connection end, as mentioned above. That is, the three air paths—forward rotating air path 24, reverse rotating air path 25, and vacuum air source air path 26—comprising a total of three air source connection ends and three workpiece connection ends.

[0063] In this embodiment, the mounting hole 23 of the docking component is located at the center of the piston shaft 2 of the docking cylinder, that is, the center of the quick docking unit 3, and the docking air path is uniformly arranged around the quick docking unit 3. This structure can improve the docking accuracy between the air path docking cylinder 013 and the pneumatic actuator to be driven.

[0064] According to a specific embodiment of this utility model, a protruding piston ring 28 is provided on the outer side of the piston shaft 2 of the docking cylinder; the cylinder driving air passage includes a piston extension air passage 11 and a piston retraction air passage 12; the two ends of the piston extension air passage 11 are respectively an extension air source end 111 and an extension driving end 112, and the two ends of the piston retraction air passage 12 are respectively a retraction air source end 121 and a retraction driving end 122. The extension air source end 111 and the retraction air source end 121 are both located on the side wall of the docking cylinder body 1 near the air source end; the extension driving end 112 enters the docking cylinder body 1 and is located on one side of the piston ring 28, and the retraction driving end 122 enters the docking cylinder body 1 and is located on the other side of the piston ring 28.

[0065] More specifically, the lateral outer contour of the piston ring 28 is elongated, a structure designed to prevent rotation.

[0066] More specifically, the piston shaft 2 and piston ring 28 of the docking cylinder are integrated into one structure, which can enhance sealing and mechanical properties.

[0067] In this embodiment, the piston extension air passage 11 and the piston retraction air passage 12 are used to drive the piston shaft 2 of the docking cylinder to extend and retract, respectively. The extension air source end 111 and the retraction air source end 121 are located on the side wall of the docking cylinder body 1 near the air source end. This allows the connectors and pipelines of the power air source to be concentrated on the side of the air passage docking cylinder 013 away from the main shaft, avoiding interference and improving safety and reliability.

[0068] Please refer to this carefully. Figure 3-8This utility model also discloses an anti-interference machine tool loading and unloading tool holder clamp 100. The anti-interference machine tool loading and unloading tool holder clamp 100 is applied to a machine tool, which includes a spindle seat 300 and a machine tool spindle 400 mounted on the spindle seat 300. A recessed tool holder interface is provided below the machine tool spindle 400. The anti-interference machine tool loading and unloading tool holder clamp 100 includes a fixed air supply module 01 and a movable tool holder gripper module 02. The fixed air supply module 01 includes a mounting plate 011, a mounting base 012, and the aforementioned air path docking cylinder 013. One side of the mounting plate 011 is mounted on the spindle seat 300, and the mounting base 012 is fixedly mounted on the lower part of the other side of the mounting plate 011. The docking cylinder body 1 is fixedly mounted on the lower part of the mounting base 012. The movable tool holder gripper module 02 includes a tool holder body 021, an air distribution block 022, and a suction cup at the end, which are fixedly connected from top to bottom. The pneumatic rotary cylinder 023 of 0235; the air distribution block 022 is provided with a docking groove 0225 that matches the shape of the connector 331; the air distribution block 022 is provided with a raised air passage 024, and the workpiece end is a groove that matches the shape of the air passage 024; the anti-interference machine tool loading and unloading tool holder fixture 100 includes a spindle-connected state. When the air path docking cylinder 013 is in the spindle-connected state, the upper part of the tool holder body 021 is installed in the tool holder interface, the air distribution block 022 is located on one side of the piston shaft 2 of the docking cylinder, and the connector 331 is set directly opposite the docking groove 0225, and the air passage 024 is set directly opposite the workpiece end; the anti-interference machine tool loading and unloading tool holder fixture 100 also includes an air path-connected state. When the anti-interference machine tool loading and unloading tool holder fixture 100 is in the air path-connected state, the piston shaft 2 of the docking cylinder extends out, and the connector 331 is inserted into the docking groove 0225, and the air passage 024 is inserted into the workpiece end.

[0069] In this embodiment, the fixed air supply module 01 is fixedly installed on the lower part of the spindle seat 300 for connecting to the power air source. The movable tool holder gripper module 02 is a movable structure, wherein the structure of the tool holder body 021 is the same as the existing general tool holder structure. The movable tool holder gripper module 02 can be installed as a whole on the tool holder interface or as a whole in the machine tool magazine. The air distribution block 022 is used to dock with the piston shaft 2 of the docking cylinder and guide the power source to the pneumatic rotary cylinder 023 to drive the pneumatic rotary cylinder 023 to rotate and provide vacuum suction for the suction cup 0235. The vacuum air source air passage 26 is used to provide suction power for the suction cup 0235. The suction cup 0235 is used to adsorb workpieces 500 such as glass from mobile phones or tablet computers. Under the action of pneumatics, the pneumatic rotary cylinder 023 can drive the suction cup 0235 to rotate to adjust the orientation to pick up the workpiece 500, or adjust the workpiece 500 adsorbed by the suction cup 0235 to the required angle to complete the automatic loading and unloading of the workpiece 500.

[0070] The fixed air supply module 01 and the movable tool holder gripper module 02 of this invention adopt a transverse air path docking structure. Specifically, the piston shaft 2 of the docking cylinder 013 can extend and retract laterally to dock with or disengage from the movable tool holder gripper module 02. After docking, the power air source is supplied to the movable tool holder gripper module 02. After disengagement, the movable tool holder gripper module 02 can be removed by the tool changing robot and transferred to the tool magazine.

[0071] Compared with the prior art, in this embodiment, the air path docking cylinder 013 belongs to the fixed air supply module 01 and not to the movable tool holder gripper module 02. The air path docking cylinder 013 will not move into the tool magazine with the movable tool holder gripper module 02 as a whole, which can effectively reduce the lateral dimension of the movable tool holder gripper module 02, making it flexible and convenient to move, and avoiding interference when the movable tool holder gripper module 02 enters the tool magazine.

[0072] According to a specific embodiment of the present invention, the mounting plate 011 is plate-shaped in general.

The rotary cylinder forward rotation air path 0231, rotary cylinder reverse rotation air path 0232, rotary cylinder vacuum air path 0223, and rotary cylinder indexing detection air path 0224 are respectively set up with corresponding rotary cylinder forward rotation air path 0231, rotary cylinder reverse rotation air path 0232, rotary cylinder vacuum air path 0233, and rotary cylinder indexing detection air path 0234. The rotary cylinder forward rotation air path 0221, rotary rotation air path 0222, rotary cylinder vacuum air path 0223, and rotary cylinder indexing detection air path 0224 are respectively connected to the rotary cylinder forward rotation air path 0231, rotary cylinder reverse rotation air path 0232, rotary cylinder vacuum air path 0233, and rotary cylinder indexing detection air path 0234. The rotary cylinder vacuum air path 0233 is also connected to the suction cup 0235; anti-interference machine tool loading and unloading tool holder fixture 10 When the cylinder is in the connected air path state, the forward rotating air path 24, the reverse rotating air path 25, the vacuum source air path 26, and the rotation position detection air path 27 are respectively connected to the forward rotating air path 0221, the reverse rotating air path 0222, the vacuum air path 0223, and the rotation position detection air path 0224 of the gas distribution system; the pneumatic rotary cylinder 023 also includes a rotary cylinder shaft 0236 rotatably connected to the rotary cylinder body 0237, and a suction cup 0235 is fixedly connected to the rotary cylinder shaft 0236. The rotary cylinder shaft 0236 is provided with a first detection air hole 02361 and a second detection air hole 02362 that penetrate radially through it. The diameter of the first detection air hole 02361 is different from the diameter of the second detection air hole 02362; connected air path The path states include a vertical suction cup setting state and a horizontal suction cup setting state. When the anti-interference machine tool loading and unloading tool holder 100 is in the vertical suction cup setting state, the suction cup 0235 is vertically set, and the rotary cylinder indexing detection air passage 0234 is connected to the first detection air hole 02361. When the anti-interference machine tool loading and unloading tool holder 100 is in the horizontal suction cup setting state, the suction cup 0235 is horizontally set, and the rotary cylinder indexing detection air passage 0234 is connected to the second detection air hole 02362. The rotary cylinder body 0237 is provided with an exhaust hole 0238. The upper part of the exhaust hole 0238 is connected to both the first detection air hole 02361 and the second detection air hole 02362, and the lower part of the exhaust hole 0238 penetrates through the rotary cylinder body 0237.

[0075] More specifically, the rotary cylinder shaft 0236 is provided with a shaft vacuum passage 02363 that connects the rotary cylinder vacuum passage 0233 and the suction cup 0235.

[0076] In this embodiment, the piston shaft of the docking cylinder, the air distribution block 022, and the pneumatic rotary cylinder 023 are respectively provided with interconnected forward rotation air path, reverse rotation air path, vacuum air path, and detection air path to achieve air path connectivity.

[0077] The first detection air port 02361 and the second detection air port 02362 are respectively located on the rotating shaft 0236 of the rotary cylinder. When the suction cup 0235 is vertically set, the rotary cylinder indexing detection air passage 0234 is connected to the first detection air port 02361; when the suction cup 0235 is horizontally set, the rotary cylinder indexing detection air passage 0234 is connected to the second detection air port 02362. Rotating the rotating shaft 0236 allows the rotary cylinder indexing detection air passage 0234 to be connected to either the first detection air port 02361 or the second detection air port 02362. Since the diameters of the first and second detection air ports are different, the air pressure in the rotary cylinder indexing detection air passage 0234 will also differ when it is connected to detection ports of different diameters. By detecting the air pressure in the detection air passage, it can be determined which specific detection port the rotary cylinder indexing detection air passage 0234 is currently connected to. This indirectly determines whether the anti-interference machine tool loading / unloading tool holder 100 is in a horizontal or vertical suction cup setting. In practice, the difference between the diameter of the first detection air hole 02361 and the diameter of the second detection air hole 02362 can be increased. For example, the diameter of the first detection air hole 02361 can be 1.5-2.5 times the diameter of the second detection air hole 02362, resulting in a larger difference in the pressure value of the detection air path when connected to different detection holes, thus improving the convenience of judgment. The exhaust hole 0238 connects the detection hole (either the first detection air hole 02361 or the second detection air hole 02362) to the external space, forming a smooth detection air path.

[0078] According to a specific embodiment of this utility model, the anti-interference machine tool loading and unloading tool holder 100 further includes a pressure gauge (not shown) connected to the rotational position detection air passage 27 and used to detect the air pressure value of the rotational position detection air passage 27; the air passage 024 is a protruding structure for air passage docking, preferably, the air passage 024 is made of rubber material. The air passage 024 can be a simple straight-through structure formed by a hollow cylinder, and the outer edge of the end of the air passage 024 is chamfered, and sealing rings are provided on the outer sides of both ends.

[0079] In this embodiment, the air pressure in the detection air path can be visually displayed using an air pressure gauge to determine whether the suction cup 0235 is set vertically or horizontally. The rubber material of the air inlet 024, which is pressed against the workpiece end, improves the sealing of the air path connection.

[0080] Please refer to this carefully. Figure 9 This utility model also discloses a multi-station rotary table 200, including the air path docking cylinder 013 as described above. The multi-station rotary table 200 also includes a rotatable turntable 201, on which multiple pneumatic actuation stations are provided. The multiple pneumatic actuation stations are arranged around the rotation center of the rotatable turntable 201. Each pneumatic actuation station is provided with a pneumatic actuator 202. The air path docking cylinder 013 is located on one side of the turntable body and is used to provide a driving air source for the pneumatic actuator 202. Each pneumatic actuator 202 is provided with an air source docking interface that docks with the air path docking cylinder 013.

[0081] More specifically, the pneumatic actuator 202 may be a pneumatic telescopic cylinder, a pneumatic translational gripper, or a pneumatic rotary gripper.

[0082] The pneumatic connection cylinder 013 in this invention has a pneumatic connection function. Besides providing air supply for tool holder grippers in the machine tool field, the pneumatic connection cylinder 013 can also be used for pneumatic connection in other fields. For example, in the multi-station rotary table 200 described in this embodiment, if it has eight pneumatic actuator stations and is equipped with one pneumatic connection cylinder 013, it is suitable for situations where only one station needs air supply at a time. If two stations need air supply simultaneously, two pneumatic connection cylinders 013 are correspondingly provided. The rotatable rotary table 201 rotates by a corresponding angle to ensure that the pneumatic actuator 202 requiring air supply is aligned with the pneumatic connection cylinder 013 on one side. The piston shaft 2 of the pneumatic connection cylinder extends, and after completing the pneumatic connection, air is supplied to the pneumatic actuator 202, driving it to operate. After the pneumatic actuator 202 completes its operation, the piston shaft 2 of the pneumatic connection cylinder retracts.
