[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a multi-station adaptive positioning auxiliary device for machine tool processing, such as... Figs. 1-2 As shown, the machine tool processing multi-station adaptive positioning auxiliary device includes a mounting base 1 for fixing on the machine tool station and a clamping mechanism 3 fixedly installed on the mounting base 1. A conveying mechanism 2 for conveying pipe fittings is provided in the middle of the clamping mechanism 3 and fixedly installed on the mounting base 1.

[0024] The clamping mechanism 3 includes side frames 31 symmetrically fixed on both sides of the conveying mechanism 2, electric telescopic rods 32 respectively fixed on the two side frames 31 and arranged opposite each other, a top block 33 fixedly connected to the movable end of the electric telescopic rod 32, a buffer head 34 fitted outside the top block 33 and moving closer to or away from the top block 33 to contact the end of the pipe fitting, a spring 35 fixedly installed between the top block 33 and the buffer head 34, and a pressure sensor 36 fixedly installed between the top block 33 and the buffer head 34, wherein the output end of the pressure sensor 36 is connected to the controller input end of the electric telescopic rod 32.

[0025] In use, the pipe fitting is conveyed to the designated position by the conveying mechanism 2. The electric telescopic rod 32 drives the top block 33 to initially contact the end of the pipe fitting with the buffer head 34. When the buffer head 34 contacts the pipe fitting, the spring 35 begins to compress. At the same time, the pressure sensor 36 detects the contact pressure. When the pressure reaches the preset threshold, the pressure sensor 36 sends a signal to the controller of the electric telescopic rod 32. The controller adjusts the extension of the electric telescopic rod 32 according to the received pressure signal to ensure that the buffer head 34 applies an appropriate clamping force to the pipe fitting. After adjustment, the buffer head 34 stably clamps the pipe fitting, ensuring that the pipe fitting maintains the correct position during processing. It can match pipe fittings of different lengths and sizes, and can achieve precise and stable positioning, avoiding the need for frequent manual adjustment of the positioning device, thereby improving the processing efficiency of different models of pipe fittings in the same batch.

[0026] Specifically, the conveying mechanism 2 comprises a conveying frame 21 fixedly installed on the mounting base 1, drive rollers 22 and auxiliary rollers 23 symmetrically arranged on both sides of the conveying frame 21 and rotationally connected to both ends of the same side of the conveying frame 21, a conveying belt 24 sleeved outside the drive rollers 22 and the auxiliary rollers 23, a motor 25 fixedly installed on the mounting base 1 and having an output shaft connected to the drive rollers 22, and a plurality of V-shaped holders 241 for placing pipe fittings and arranged at equal intervals on the conveying belt 24; the motor 25 is started to drive the drive rollers 22 to rotate, thereby driving the conveying belt 24 and the auxiliary rollers 23 to rotate. The pipe fittings are placed on the V-shaped holders 241 and are conveyed to between the clamping mechanisms 3 along with the movement of the conveying belt 24. Through continuous driving of the motor 25, the conveying belt 24 can continuously convey the pipe fittings to the clamping mechanisms 3 for positioning and clamping, so as to realize automatic machining.

[0027] It should be noted that the motor 25, the electric telescopic rod 32 and the pressure sensor 36 are connected with an external control system; through the connection with the external control system, real-time monitoring and operation are realized, so as to facilitate timely error correction.

[0028] Further, the conveying frame 21 is fixedly installed with guide rails 26 on both sides for guiding the pipe fittings to be aligned between the clamping mechanisms 3, and the top of each guide rail 26 is provided with a limiting flange 261 for preventing the pipe fittings from being separated from the V-shaped holders 241; the guide rails 26 and the limiting flanges 261 jointly ensure that the pipe fittings maintain correct positions and postures during the conveying process, so as to avoid deviation of the pipe fittings from the predetermined path or falling.

[0029] Embodiment 2

[0030] Different from embodiment 1, when multiple pipe fittings need to be machined simultaneously and the models and sizes are different, a single clamping station can only meet the machining of a single pipe fitting, and the overall efficiency still has room for improvement. Therefore, the clamping mechanism 3 is provided with at least two groups for simultaneous positioning and machining of multiple pipe fittings, and the spacing between the adjacent two groups of clamping mechanisms 3 is equal to the spacing of the V-shaped holders 241.

[0031] The clamping mechanisms 3 are arranged in parallel on both sides of the conveying mechanism 2, and each set of clamping mechanisms 3 is provided with independent electric telescopic rods 32, top blocks 33, buffer heads 34, springs 35 and pressure sensors 36 and other components to ensure accurate clamping of the respective responsible pipe fittings. After the motor 25 is started, the conveying belt 24 drives the pipe fittings on the V-shaped bracket 241 to move continuously, and when the pipe fittings reach the preset position, the electric telescopic rods 32 of each set of clamping mechanisms 3 are simultaneously started to drive the top blocks 33 and the buffer heads 34 to approach the pipe fittings until the preset clamping force is reached. At this time, the pressure sensor 36 feeds back the real-time detected clamping force to the control system, and the control system adjusts the extension amount of the electric telescopic rod 32 according to the feedback signal to ensure that each set of clamping mechanisms 3 can apply appropriate clamping force to the pipe fittings. Since the spacing between the two adjacent sets of clamping mechanisms 3 is equal to the spacing of the V-shaped bracket 241, the pipe fittings can be clamped simultaneously after being clamped, so that the processing efficiency is improved, and the time waste caused by waiting for clamping is reduced.

[0032] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
