[0005] To achieve the above purpose, the utility model proposes a chain plate clamping tool for a double boring machine tool that can be hermetically detected and is easy to disassemble and assemble, including a tooling fixed plate. A number of tightening mechanisms and a number of quick-change positioning mechanisms are arranged on the tooling fixed plate. The tightening mechanisms and the quick-change positioning mechanisms are arranged in one-to-one correspondence. The quick-change positioning mechanism includes a quick-change positioning plate. Two X-direction positioning blocks are arranged on the quick-change positioning plate. Two Y-direction positioning blocks and a guiding positioning mechanism located between the two Y-direction positioning blocks are arranged at the left edge of the quick-change positioning plate. Two workpieces to be processed are placed between the two X-direction positioning blocks. The guiding positioning mechanism and the tightening mechanism are located between the two workpieces to be processed. The two workpieces to be processed are pressed and fixed on the quick-change positioning plate by a Z-direction pressing plate driven by a pressing oil cylinder. A number of airtight detection mechanisms are arranged on the quick-change positioning plate to detect whether the corresponding workpiece to be processed is closely attached to the quick-change positioning plate.

[0006] Preferably, the airtight detection mechanism includes an air supply pipe and a pressure sensor arranged on the air supply pipe. A number of through holes are arranged on the quick-change positioning plate. The upper ends of the through holes are closed by the corresponding workpieces to be processed. The output end of the air supply pipe is communicated with the corresponding through holes.

[0007] Preferably, the pressing mechanism includes a pressing oil cylinder, and an isosceles trapezoidal stopper is provided at the driving end of the pressing oil cylinder through an extension rod.

[0008] Preferably, the guiding and positioning mechanism includes a support and an isosceles trapezoidal support body provided on the support.

[0009] Preferably, the quick-change positioning plate is detachably fixed on the tooling fixing plate through a plurality of ball lock systems.

[0010] Preferably, tooling feet are provided at the bottom of the tooling fixing plate.

[0011] Advantages of the present utility model: In the present utility model, two workpieces to be processed are placed between two X-direction positioning blocks, and the pressing mechanism and the guiding and positioning mechanism are located between the two workpieces to be processed. Then, the pressing oil cylinder is started, and the isosceles trapezoidal stopper is driven by the extension rod to pre-press the two workpieces to be processed, pushing the workpieces to be processed into position. Then, the pressing oil cylinder for driving the Z-direction pressing plate is started to press and fix the workpieces to be processed on the quick-change positioning plate. Then, the air supply pipe is ventilated, and the pressure of the air supply pipe is detected by the air pressure sensor. When the workpieces to be processed do not fit tightly with the quick-change positioning plate 1, the gas will leak from between the workpieces to be processed and the quick-change positioning plate, and the pressure sensor on the air supply pipe detects a decrease in pressure, thereby determining that the workpieces to be processed do not fit tightly with the quick-change positioning plate. Compared with the prior art, it has good adaptability and can detect whether the chain plate is firmly fixed.

[0016] Refer to Figure 1 、 2, the utility model relates to a chain plate clamping tooling for a double boring machine tool that can be hermetically detected and is easy to disassemble and assemble, including a tooling fixing plate 14. A plurality of jacking mechanisms and a plurality of quick-change positioning mechanisms are arranged on the tooling fixing plate 14. The jacking mechanisms and the quick-change positioning mechanisms are arranged in one-to-one correspondence. The quick-change positioning mechanism includes a quick-change positioning plate 1. Two X-direction positioning blocks 4 are arranged on the front and back of the quick-change positioning plate 1. Two Y-direction positioning blocks 6 and a guiding and positioning mechanism located between the two Y-direction positioning blocks 6 are arranged at the left edge of the quick-change positioning plate 1. Two workpieces to be machined 3 are placed between the two X-direction positioning blocks 4. The guiding and positioning mechanism and the jacking mechanism are located between the two workpieces to be machined 3. The two workpieces to be machined 3 are pressed and fixed on the quick-change positioning plate 1 by a Z-direction pressing plate 10 driven by a pressing oil cylinder. A plurality of airtight detection mechanisms 15 are arranged on the quick-change positioning plate 1 to detect whether the corresponding workpiece to be machined 3 is closely attached to the quick-change positioning plate 1.

[0017] The airtight detection mechanism 15 includes an air supply pipe 151 and a pressure sensor 152 arranged on the air supply pipe 151. A plurality of through holes 16 are arranged on the quick-change positioning plate 1. The upper ends of the through holes 16 are closed by the corresponding workpieces to be machined 3. The output end of the air supply pipe 151 is communicated with the corresponding through holes 16.

[0018] The jacking mechanism includes a jacking oil cylinder 11. An isosceles trapezoidal stop block 13 is arranged at the driving end of the jacking oil cylinder 11 through an extension rod 12.

[0019] The guiding and positioning mechanism includes a support 8 and an isosceles trapezoidal support body 9 arranged on the support 8.

[0022] The working process of the utility model:

[0023] During the working process of a chain plate clamping tooling for a double boring machine, which is airtight detectable, easy to disassemble and assemble, different quick-change positioning plates (adopting a ball lock system and can be quickly disassembled and replaced) are selected according to different specifications of workpieces to be machined. Two workpieces 3 to be machined are placed between two X-direction positioning blocks 4, and the jacking mechanism and the guiding and positioning mechanism are located between the two workpieces 3 to be machined. Then, the jacking oil cylinder is started to drive an isosceles trapezoidal block through an extension rod to pre-jack the two workpieces 3 to be machined, and the workpiece 3 to be machined is jacked to the position. Then, the pressing oil cylinder for driving the Z-direction pressing plate 10 is started to press and fix the workpiece 3 to be machined on the quick-change positioning plate 1 (the workpiece to be machined is clamped by adopting a three-point and two-surface positioning method). Then, the air supply pipe is ventilated, and the pressure of the air supply pipe is detected by a pressure sensor. When the workpiece 3 to be machined is not closely attached to the quick-change positioning plate 1, the gas will leak from between the workpiece 3 to be machined and the quick-change positioning plate 1, and the pressure sensor on the air supply pipe detects a decrease in pressure, so as to judge that the workpiece 3 to be machined is not closely attached to the quick-change positioning plate 1 (judge whether the workpiece to be machined is always closely attached to the quick-change positioning plate in the automatic working state). Compared with the prior art, it has good adaptability and can detect whether the chain plate is firmly fixed.
