[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific examples disclosed in the following description.

[0024] Example 1: please refer to Figures 1-4 As shown in the utility model provides a kind of feeding mechanism of machine tool, comprising: first motor 1, the output end of first motor 1 is fixedly installed with screw rod 2, the outer wall of screw rod 2 is threadedly connected with bearing seat 3, the top of bearing seat 3 is fixedly installed with erection platform 4, the bottom of erection platform 4 is fixedly installed with sliding block 5, the inside of sliding block 5 is slidably connected with limit seat 6, the top of erection platform 4 is fixedly installed with dust cover 7, the top of erection platform 4 is fixedly installed with telescopic suction mechanism 8

[0025] The effect achieved by the whole example 1 is that the first motor is the starting power source of the entire feeding process automation, it is closely connected with the screw rod, when the motor is running, the stable torque generated is accurately transmitted to the screw rod, to make the screw rod rotate with high precision, the screw rod and bearing seat are connected by screw thread, and the mechanical structure can convert the rotary motion of the screw rod into the linear motion of the bearing seat along the axial direction of the screw rod, so that the erection platform fixed to the top of the bearing seat is driven to move linearly with high precision, this process completely eliminates the tediousness and uncertainty of traditional manual feeding, and realizes automatic feeding, the second motor

[0026] Example 2: please refer to asFigures 1-4 As shown, the telescopic adsorption mechanism 8 includes a second motor 801, the output end of the second motor 801 is fixedly connected with a gear 802, the outer wall of the gear 802 is engaged with a rack 803, one end of the rack 803 is fixedly connected with a mounting platform 804, the top of the mounting platform 804 is fixedly installed with a high-pressure air pump 805, the bottom of the mounting platform 804 is fixedly connected with an electric telescopic rod 806, the bottom of the mounting platform 804 is fixedly connected with a group of balance telescopic rods 807, the bottom of the balance telescopic rods 807 is fixedly connected with an adsorption platform 808, the high-pressure air pump 805 and the adsorption platform 808 are communicated with an air pipe 809, and the outer wall of the rack 803 is slidably attached with a first bracket 10 and a second bracket 11.

[0027] The effect achieved by the whole embodiment 2 is that the second motor drives the gear to rotate, the rack closely engaged with the gear starts to move horizontally under the driving of the gear, at the same time, the electric telescopic rod flexibly performs the telescopic movement in the vertical direction according to the preset program instructions, and the two movement modes cooperate with each other, so that the adsorption platform can realize accurate positioning in three-dimensional space. For example, in the automatic production line of 3C product parts processing, facing small and complex parts, the automatic feeding mode of the feeding mechanism can quickly and accurately transport the parts to the specified processing position according to the preset program, the whole process is completed at one time, greatly reducing manual intervention, which not only reduces labor cost, but also avoids errors that may be caused by manual operation, effectively guarantees the stability of feeding accuracy and efficiency, significantly improves the overall production rhythm, meets the strict demand of large-scale and high-efficiency production, three-dimensional positioning: three-dimensional positioning of the adsorption platform is realized through horizontal transmission of the gear and rack + vertical movement of the electric telescopic rod pressure balance: the balance telescopic rod group ensures that the adsorption platform is always in a horizontal state flexible adsorption: the high-pressure air pump cooperates with the adsorption platform to realize reliable grabbing of workpieces of different materials overload protection: the rack and the double-bracket sliding cooperation structure can absorb the movement impact

[0028] Working principle: initial standby state: after the feeding mechanism is turned on, the first motor, the second motor and the electric telescopic rod are all in a static state, and the telescopic suction mechanism is located at the preset standby position. At this time, the high-pressure gas pump is not started, and the suction platform has not generated suction force. The entire mechanism is like a "hunter" waiting for work instructions. Precise positioning stage: the control system sends a positioning instruction. The first motor responds first. Its output shaft drives the screw to rotate quickly. Since the screw is closely connected with the bearing seat through threads, the bearing seat moves along the axial direction of the screw, thereby pushing the top erection platform to move precisely along the horizontal guide rail to the target work station under the guidance of the sliding block and the limiting seat. Then, the second motor starts, and the gear connected to its output end begins to rotate. The rack meshing with the gear produces displacement in the horizontal direction, driving the installation platform fixed at one end of the rack to move horizontally. At the same time, the electric telescopic rod is elongated or shortened according to the height information of the workpiece under the control of the control system, so that the suction platform moves precisely above the workpiece, completing the three-dimensional precise positioning of the spatial position. Reliable grabbing stage: after the suction platform reaches the specified position above the workpiece, the electric telescopic rod starts to descend at a uniform speed, driving the suction platform to gradually approach the workpiece. In this process, the balance telescopic rod works synchronously. Through the built-in sensor, the horizontal state of the suction platform is monitored in real time, and the length of the balance telescopic rod is automatically adjusted to ensure that the suction platform is always in a horizontal posture. When the suction platform approaches the workpiece surface to a certain distance, the high-pressure gas pump starts to deliver high-pressure gas to the suction platform through the air pipe, forming a negative pressure between the suction platform and the workpiece, tightly sucking the workpiece on the suction platform, and completing the grabbing action. Smooth transfer stage: after the workpiece is reliably grabbed, the first motor is reversed to drive the screw to rotate in the opposite direction, driving the erection platform and the telescopic suction mechanism with the workpiece to move towards the machine tool machining station. During the transfer process, the components work cooperatively to maintain a smooth running state, ensuring that the workpiece does not shake or deviate during the transfer process. The electric telescopic rod adjusts the length in time according to the height requirement during the transfer process to ensure that the workpiece is smoothly transferred to the machine tool machining area. Precise release stage: after the feeding mechanism moves to the appropriate position above the machine tool machining station, the high-pressure gas pump stops supplying gas, and the negative pressure between the suction platform and the workpiece disappears. The workpiece falls precisely onto the machine tool machining table under the action of its own gravity. Then, the electric telescopic rod is retracted to lift the suction platform to the initial height, and the balance telescopic rod is reset synchronously to prepare for the next feeding cycle. During the entire working process, the stages are closely connected, and the automation, precision and high efficiency of the feeding work are realized through the cooperative operation of the motor, screw, gear and rack, telescopic rod and gas pump and other components.
