Description

Technical Field

[0001] This utility model relates to the field of locking structure technology, specifically an automatic locking structure for a milling machine worktable. Background Technology

[0002] In milling, workpiece fixation is crucial for ensuring machining accuracy and efficiency. Traditional milling machine table locking methods typically use manual clamps or bolts, which have several drawbacks.

[0003] First, manually fixing the workpiece is not only cumbersome and time-consuming, but it is also prone to loosening or insecure clamping during the fixing process, which can cause the workpiece to shift during processing and affect the processing accuracy.

[0004] Secondly, manual fixing methods are poorly adaptable to workpieces of different shapes and sizes, requiring frequent changes of fixtures or adjustments to the fixing method, further reducing machining efficiency. Therefore, improving the convenience, firmness, and adaptability of workpiece locking on the milling machine table is a pressing issue in the milling machining field.

[0005] This invention addresses the shortcomings of existing milling machine table locking methods by proposing an automatic locking structure. Through ingenious pneumatic and magnetic design, it achieves rapid and automatic workpiece locking, effectively solving the problems of cumbersome operation, poor adaptability, and low safety associated with traditional manual fixing methods, and greatly improving the efficiency and accuracy of milling machine processing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automatic locking structure for a milling machine worktable, solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic locking structure for a milling machine worktable, comprising a lathe, a push rod, and a lifting tube. Two pressure chambers are mounted on the surface of the lathe. A push rod is installed inside each pressure chamber. One end of each pressure chamber is connected to a connecting pipe. Two connecting pipes are provided, both connected to a lifting groove. A lifting tube is installed inside the lifting groove. A tray is welded to the top of each lifting tube. A first magnet is installed at the bottom of the tray. A second magnet is installed below the first magnet. The second magnet is embedded inside the lathe. One side of the lifting groove is connected to a three-way pressure relief valve. One end of the three-way pressure relief valve is connected to an external air pump, and the other end is connected to the outside.

[0008] Preferably, multiple push rods are provided, the surface of the push rods slides in contact with the pressure chamber, and one end of the push rod is made of rubber. The rubber material helps to protect the workpiece and prevent the workpiece from being damaged due to excessive tightening by the push rod.

[0009] Preferably, the push rod has a hollow internal structure, and one end of the push rod is provided with an annular protrusion. A spring is fitted on the outside of the push rod, and one end of the push rod is open. The push rod is used to fix the lower end of the workpiece, and pressure is applied to the upper end of the workpiece to prevent it from being accidentally damaged by the push rod. A groove is provided on the surface of one end of the push rod to ensure that gas can smoothly enter the interior of the push rod.

[0010] Preferably, the outer wall of the lifting pipe is provided with holes and grooves that communicate with the interior, and the holes and grooves inside the lifting pipe are distributed in an annular shape with equal spacing, which helps to ensure that the three-way pressure relief valve can communicate with the connecting pipe.

[0011] Preferably, the groove on the outer wall of the lifting pipe is connected to the connecting pipe and the three-way pressure relief valve through a lifting mechanism, so that the tray can move the lifting pipe downwards, thereby allowing the groove inside the lifting pipe to connect with the three-way pressure relief valve and the connecting pipe.

[0012] Preferably, the first magnet and the second magnet at the bottom of the lifting tube are in a repulsive state, and the locking force of the top rod on the workpiece is greater than the repulsive force between the first magnet and the second magnet.

[0013] This utility model provides an automatic locking structure for a milling machine worktable. It has the following beneficial effects:

[0014] (1) The automatic locking structure of the milling machine worktable, when in use, the workpiece is placed on the tray, and then the workpiece is pressed down, so that the tray can move the lifting tube downward, so that the groove inside the lifting tube can be connected with the three-way pressure relief valve and the connecting pipe, so that the external high pressure gas can enter the connecting pipe through the three-way pressure relief valve, and finally enter the pressure chamber, so that the high pressure gas can push out the push rod, so that the push rod can automatically lock the workpiece, thereby greatly improving the convenience of fixing the workpiece.

[0015] (2) The automatic locking structure of the milling machine worktable allows the air inside the pressure chamber to be discharged through the pressure relief valve by rotating the three-way pressure relief valve. Then, under the action of the spring, the push rod can retract and reset, and the tray can automatically reset under the action of the first magnet and the second magnet, so that the workpiece can be quickly contacted and locked, thereby further improving the convenience of use. At the same time, the structure can lock workpieces of different shapes by setting multiple push rods. Attached Figure Description
