Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to an automatic avoidance pneumatic fixture for thin plate parts. Background Art

[0002] With the rapid development and widespread application of integrated circuits and intelligent manufacturing technologies, demand for IC equipment is growing. In these advanced manufacturing fields, thin plate parts, as core components of IC equipment, play a crucial role. These parts, such as thin plate sieves, are typically thin and rectangular, with a variety of complex hollowing stations distributed throughout. However, due to their unique structure, thin plate parts are prone to deformation during processing, which increases the complexity and difficulty of machining.

[0003] Traditional machining methods often require multiple clamping cycles with pressure plates to ensure part precision and stability. However, this method is not only inefficient but also increases worker workload. Furthermore, with the continuous advancement of modern mechanical manufacturing technology, traditional manufacturing processes are no longer able to meet the current industry development needs.

[0004] Therefore, it is particularly important to develop a new technology that can process thin plate parts efficiently and stably. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an automatic avoidance pneumatic jig for thin plate parts. The automatic avoidance pneumatic jig for thin plate parts not only improves the processing accuracy and stability, but also significantly improves the clamping efficiency and processing efficiency, reduces the labor intensity of workers, and enhances the flexibility of the jig. It has broad application prospects and significant economic benefits.

[0006] The technical solution of the utility model is as follows:

[0007] A pneumatic jig for automatic avoidance of thin plate parts includes a raised seat, a base plate, a pressure plate and a rotating cylinder. The base plate is fixedly installed on the raised seat, and the thin plate parts to be processed are placed on the base plate.

[0010] A bushing is sleeved on the exterior of the positioning pin.

[0011] The pressure plate is an "L"-shaped plate structure, and an oblong hole is provided on the horizontal plate of the pressure plate. The bolt passes through the oblong hole and is threadedly connected to the piston rod of the rotary cylinder, so that the horizontal plate part of the pressure plate is fixed on the piston rod of the rotary cylinder.

[0012] A compression pad is provided between the bolt and the pressure plate.

[0013] A speed regulating valve is provided on the air supply pipeline of the rotary cylinder.

[0014] A pneumatic triplex is provided on the air supply pipeline of the rotary cylinder.

[0015] The on and off of the rotary cylinder is controlled by a solenoid valve.

DETAILED DESCRIPTION

[0033] like Figure 1As shown, the automatic avoidance pneumatic fixture for thin plate parts mainly consists of the following components: a raising seat 1, a base plate 2, a pressure plate 3, a pressing pad 4, a connecting plate 5, a screw assembly 6, a bushing 7, a positioning pin 8, a quick connector 9, a speed regulating valve 10, a 4-way manual valve 11, a pneumatic triplex 12 and a rotary cylinder 13.

[0034] The booster seat 1 is used to support the entire fixture to ensure that the fixture is stable and reliable during operation. For specific appearance and structure, see Figure 2 .

[0035] The bottom plate 2 is fixedly mounted on the raised seat 1 and serves as a support platform for the thin plate parts to be processed. Figure 3 shown.

[0036] like Figure 4 As shown in the figure, the pressure plate is designed as an "L"-shaped plate structure, which is fixedly connected to the piston rod of the rotary cylinder by bolts; oblong holes are provided on the horizontal plate of the pressure plate to facilitate the adjustment and fixation of the bolts; during processing, the pressure plate is used to press thin plate parts to prevent them from moving or deforming.

[0037] The compression pad 4 is set between the bolt and the pressure plate to increase the compression force and protect the thin plate parts from damage, such as Figure 5 shown.

[0038] The connecting plate 5 is used to install the pneumatic triple lift 12 on the booster seat 1. Figure 6 shown.

[0039] The screw assembly 6 is used to fix the components to each other.

[0040] At least three positioning pins 8 are set between the base plate 2 and the thin plate parts to roughly position the parts and improve the clamping efficiency; the outer sleeve of the positioning pin 8 is provided with a bushing 7 to reduce wear and improve positioning accuracy.

[0041] The quick connector 9 is used for the quick connection of the air supply line of the rotary cylinder 13 .

[0042] The speed regulating valve 10 is arranged on the air supply line of the rotary cylinder to adjust the clamping and opening speed of the cylinder to avoid the clamping speed being too fast to crush the parts or the opening speed being too slow to affect the processing efficiency.

[0043] The pneumatic triplex 12 is also provided on the air supply line of the rotary cylinder and is used to filter, reduce pressure and lubricate the compressed air to ensure the normal operation of the cylinder.

[0044] Rotating cylinder 13 is installed on the heightening seat by fixed base, and its piston rod is fixedly connected with pressing plate. Under the control of electromagnetic valve, rotating cylinder can realize the clamping and unclamping action of pressing plate.

[0045] The solenoid valve receives the electrical signal from the machine tool program code to control the on and off of the rotary cylinder to achieve the function of automatic tool avoidance.

[0046] The 4-way manual valve 11 is used as a backup control means. When the machine tool code control is invalid or manual intervention is required, the 4-way manual valve can be used to control the opening and tightening of the pressure plate respectively.

[0047] Steps for using the automatic avoidance pneumatic fixture for thin plate parts:

[0048] (1) The thin plate parts to be processed are roughly positioned by three positioning pins and quickly placed in the designated position;

[0049] (2) Rotate the 4-way manual valve to tighten all the pressure plates. At this time, the parts are in a state of waiting for processing inside the machine tool;

[0050] (3) When compiling a part processing program, set signal instructions when the tool is 100 mm close to the rotating platen and 100 mm away from the rotating platen;

[0051] (4) After the machine tool receives the signal instruction in the program that the tool is approaching the rotating pressure plate, the solenoid valve starts to work, switches the direction of the air source, and causes the rotary cylinder to open quickly, exposing the workstation to be processed;

[0052] (5) The cutting tool starts machining the part after the rotary cylinder is opened and the part is pressed by the pressure plate;

[0053] (6) When the tool is 100 mm away from the rotary pressure plate, the machine tool receives the signal instruction in the program that the tool is away from the rotary pressure plate, and the solenoid valve switches the air source direction again, so that the rotary cylinder slowly presses the part and prepares for the next station processing;

[0054] (7) Through one cycle of opening and clamping, one side of the workstation can be fully processed without stopping the machine for clamping;

[0055] (8) When the program avoids or the solenoid valve fails, the 4-way manual valve can be used to control the opening and clamping of the pressure plate respectively to ensure that parts can still be processed in the manual state.

[0056] Through the above-mentioned implementation manner, the automatic avoidance pneumatic fixture for thin plate parts of the present invention realizes an efficient and stable processing process, reduces the labor intensity of workers, and improves processing efficiency and precision.
