[0001] The present invention relates to the technical field of automatic processing equipment, and particularly relates to an automatic loading and quick clamping interchange platform. Background Art

[0002] With the rapid development of the domestic and foreign machinery industries, the machine tool industry has also developed rapidly. Machine tools are machines used for processing various mechanical parts in modern mechanical manufacturing. There are various types of machine tools, which can be used for machining operations such as cutting, drilling, welding, stamping, and assembling of workpieces. To ensure machining accuracy and stability, when machining a workpiece, a clamping platform is required to clamp the workpiece. When the existing automatic loading and clamping platform replaces the workpiece, it is necessary to clamp the material transportation platform through a robotic arm, and when replacing the material transportation platform, it is also necessary to spend time positioning the material transportation platform and the machine tool platform. When replacing the workpiece, it takes a relatively long time, resulting in a reduction in machining efficiency. Therefore, the present invention proposes an automatic loading and quick clamping interchange platform to improve this problem. Summary of the Invention

[0003] The purpose of the present invention is: to solve the problems in the above background art, the present invention provides an automatic loading and quick clamping interchange platform.

Detailed implementation mode

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] As Figures 1-6 shown, an automatic loading and quick clamping and interchange platform proposed in an embodiment of the present invention includes: A mounting bracket 1, on which a transfer platform 101 is mounted, and the transfer platform 101 is used for mounting other components of the device; A positioning platform 2, which is mounted on the machine tool platform. A positioning plate 201 is mounted on the positioning platform 2. An air inlet hole 202 is opened on the positioning plate 201. A positioning post 203 is mounted on the positioning plate 201. An airbag 204 is mounted on the positioning post 203. The airbag 204 is communicated with the air inlet hole 202. The positioning platform 2 is pre-mounted on the machine tool in advance. A plurality of air inlet holes 202 are opened on the positioning plate 201. A hole channel communicated with the air inlet hole 202 is opened in the positioning post 203, and the hole channel is communicated with the inside of the airbag 204, so that when the air in the air inlet hole 202 is exhausted, the air flow can enter the airbag 204 through the hole channel on the positioning post 203, so that the airbag 204 can expand; A loading platform 3, which is mounted on the transfer platform 101. The loading platform 3 is used for carrying workpieces. A positioning hole 301 is opened on the loading platform 3. The inner diameter of the positioning hole 301 is larger than the diameter of the positioning post 203. Since the aperture of the positioning hole 301 is larger than the rod diameter of the positioning post 203, it is convenient to position and insert the positioning hole 301 and the positioning post 203. When installing the loading platform 3 and the positioning platform 2, the loading platform 3 can be transported by a manipulator or other driving components; Compared with the prior art, when in use, the workpiece is installed on the loading platform 3. When the loading platform 3 needs to be loaded, the positioning hole 301 is aligned with the positioning column 203. Since the inner diameter of the positioning hole 301 is larger than the diameter of the positioning column 203, the positioning hole 301 can be connected with the positioning column 203 more conveniently, and then air is inflated into the air inlet 202 to expand the airbag 204, so that the airbag 204 contacts the inner wall of the positioning hole 301, and the loading platform 3 is connected with the positioning platform 2, so that the workpiece can be installed on the machine tool more accurately, which increases the convenience of using the device.

[0016] like Figure 2 and Figure 4 As shown, a partial structure of the loading platform 3 is disclosed. The loading platform 3 includes an upper plate 302 and a lower plate 303. The positioning hole 301 is opened on the lower plate 303. The upper plate 302 is connected to the transfer platform 101. A card plate 304 is installed on the upper plate 302. A card slot 305 is opened on the card plate 304. An insertion plate 306 for inserting into the card slot 305 is installed on the lower plate 303. The card plate 304 and the card slot 305 form an L-shaped structure, as shown in FIG. Figure 4 As shown, the insertion plate 306 is used to be slidably inserted in the card slot 305, so that the upper plate 302 and the lower plate 303 are connected by sliding insertion; When the device is in use, the first batch of workpieces are connected to the upper plate 302, and after the slots 305 on the upper plate 302 are aligned with the insertion plate 306, the upper plate 302 is connected to the lower plate 303, and the upper plate 302 and the lower plate 303 are transported by a manipulator or other structure so that the positioning holes 301 are connected to the positioning posts 203, and the workpieces are processed by a machine tool. When the lower plate 303 is located on the positioning platform 2, it is in a horizontal direction and its position has been fixed by the positioning platform 2. When it is necessary to process subsequent batches of workpieces, it is only necessary to slide the upper plate 302 in the horizontal direction to replace it. In the present invention, compared with the positioning between the positioning holes 301 and the positioning posts 203, by sliding the upper plate 302 in the horizontal direction, it is only necessary to ensure that the driving force of the upper plate 302 is maintained in the horizontal direction so that the upper plate 302 can be connected to the lower plate 303, which is more convenient when changing, so that the device is easy to replace workpieces.

[0017] like Figure 1 , Figure 4 and Figure 5As shown in the figure, the specific structure of the driving member 4 is disclosed. A driving member 4 is installed on the transfer platform 101. The driving member 4 includes an electric push rod 401. A convex block 402 is installed on the telescopic end of the electric push rod 401. A through hole 403 is opened on the convex block 402. A mounting plate 404 is installed on the upper plate 302. A mounting hole 405 is opened on the mounting plate 404. The height of the mounting plate 404 is higher than that of the convex block 402. When the loading platform 3 approaches the telescopic end of the electric push rod 401, the mounting plate 404 is located below the convex block 402. At this time, the through hole 403 is aligned with the mounting hole 405. Then, a pin is inserted into the mounting hole 405 to complete the connection between the upper plate 302 and the electric push rod 401. The end face of the convex block 402 contacts the side wall of the upper plate 302. The axis of the through hole 403 is located in the middle of both ends of the convex block 402. When the end of the convex block 402 abuts against the upper plate 302, if the pin is used as the rotation axis, both sides in the rotation direction are abutted and blocked by the end face of the end of the convex block 402, so that the upper plate 302 will not rotate when being pushed by the electric push rod 401, increasing the stability of the upper plate 302 during transportation, ensuring that the card slot 305 on the upper plate 302 can be kept flush with the insertion plate 306, and enabling the upper plate 302 to be smoothly inserted onto the lower plate 303. During use, since the installation position of the electric push rod 401 is fixed, the telescopic direction of its telescopic end is fixed, and the positioning platform 2 is fixed at a position on the machine tool, only by driving the upper plate 302 by the telescopic end of the electric push rod 401 can the insertion plate 306 and the card slot 305 be directly aligned. By the telescopic movement of the electric push rod 401, the upper plate 302 can approach or move away from the machine tool platform, enabling the device to replace the workpiece more conveniently.

[0018] As Figure 2 shown, a partial structure of the positioning platform 2 is disclosed. An entrance plate 5 is installed on the positioning platform 2. A rolling wheel 6 is rotatably installed on the entrance plate 5. A sliding groove 7 that slidably cooperates with the rolling wheel 6 is opened on the upper plate 302. When the upper plate 302 is transported by the electric push rod 401, since the installation position of the electric push rod 401 is fixed, the telescopic direction of its telescopic end is fixed, and the positioning platform 2 is fixed at a position on the machine tool, when the electric push rod 401 transports the upper plate 302, the sliding groove 7 can be aligned with the rolling wheel 6. When the upper plate 302 moves downward onto the lower plate 303, by the rolling of the rolling wheel 6 in the sliding groove 7, the friction between the positioning platform 2 and the upper plate 302 is reduced, further facilitating the connection between the upper plate 302 and the lower plate 303.

[0019] As Figure 4As shown in the figure, a partial structure on the lower plate 303 is disclosed. A positioning block 8 is installed on the lower plate 303. The positioning block 8 is used to be inserted into the sliding groove 7. When the upper plate 302 slides onto the lower plate 303, the positioning block 8 is inserted into the sliding groove 7. Through the connection between the positioning block 8 and the sliding groove 7, the contact area between the upper plate 302 and the lower plate 303 is increased, thereby increasing the connection strength between the upper plate 302 and the lower plate 303, and further increasing the stability of the upper plate 302 on the lower plate 303.

[0020] As Figure 2 shown in the figure, a partial structure on the lower plate 303 is disclosed. A receiving groove 9 is formed on the lower plate 303. The receiving groove 9 communicates with the air inlet hole 202. A hole passage is formed in the receiving groove 9. When the lower plate 303 is installed on the positioning platform 2, the hole passage on the receiving groove 9 communicates with the air inlet hole 202, so that the air flow in the air inlet hole 202 can flow into the receiving groove 9; A connecting plate 10 is slidably installed in the receiving groove 9. A runner 14 is rotatably installed on the connecting plate 10. When in the normal state, the connecting plate 10 sinks inside the receiving groove 9 due to gravity, and the highest point of the runner 14 is lower than the upper surface of the lower plate 303. The connecting plate 10 slides vertically in the receiving groove 9. When the air flow flows into the receiving groove 9, it blows the connecting plate 10, causing the connecting plate 10 to move upward, thereby driving the runner 14 to move upward, so that the runner 14 can contact the bottom of the upper plate 302. When it is necessary to install the upper plate 302 and the lower plate 303, the connecting plate 10 is blown by the air flow to move upward, so that the runner 14 can move to a position where it contacts the bottom of the upper plate 302. When the upper plate 302 is inserted and slid onto the lower plate 303, the rolling of the runner 14 replaces the direct friction between the two, reducing the friction between the upper plate 302 and the lower plate 303, enabling the upper plate 302 to slide better above the lower plate 303, and further increasing the convenience of the connection between the upper plate 302 and the lower plate 303.

[0021] As Figure 3 shown in the figure, a partial structure of the upper plate 302 is disclosed. A fixing plate 11 and a clamping plate 12 are installed on the upper plate 302. The clamping plate 12 is slidably installed on the upper plate 302. The upper plate 302 and the fixing plate 11 are used to clamp the workpiece. A hole passage is formed in the clamping plate 12, and a hole passage is also formed in the upper plate 302. During use, first slide the clamping plate 12 away from the fixing plate 11 to increase the distance between the two. When the workpiece is placed between the two, then slide the clamping plate 12 so that the clamping plate 12 and the fixing plate 11 clamp the workpiece. Then, connect the hole passages on the clamping plate 12 and the upper plate 302 through a pin to limit the sliding of the clamping plate 12, enabling the upper plate 302 to stably fix the workpiece, reducing the possibility of the workpiece tipping over during transportation, and increasing the practicality of the device.

[0022] As shown Figure 3 in the figure, the specific structures of the clamping plate 12 and the fixing plate 11 are disclosed. Arc-shaped grooves 13 are formed on the clamping plate 12 and the fixing plate 11. The arc-shaped grooves 13 are used to accommodate the workpiece. The formation of the arc-shaped grooves 13 on the clamping plate 12 and the fixing plate 11 enables the two to have a larger contact surface to contact with the surface of the workpiece, thereby increasing the stability of the device when clamping the workpiece.

[0023] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
