[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Embodiment 1

[0022] See also Figure 1The self-locking tuning screw receiving box automatic delivery mechanism shown includes a rotary cylinder 10, a three-axis displacement platform 20, a pneumatic clamp 30 and a pneumatic pressure block 40. The rotary cylinder 10 is installed on the X-axis slide of the three-axis displacement platform 20, the pneumatic clamp 30 is installed on the top turntable of the rotary cylinder 10, and the pneumatic pressure block 40 is fixed to the top turntable and located above the pneumatic clamp 30. The pressure block rises and falls between the two clamping plates of the pneumatic clamp 30. The pneumatic clamp 30 clamps the receiving box from the side platform, and the rotary cylinder 10 drives the pneumatic clamp 30 to rotate an angle so that the pneumatic clamp 30 faces the production equipment; then, the three-axis displacement platform 20 drives the pneumatic clamp 30 to extend into the production equipment and put the receiving box on the base submerged in the cutting fluid; finally, the pneumatic clamp 30 releases the receiving box, and the pneumatic pressure block 40 moves downward to press the receiving box on the base.

[0023] By only setting the rotation angle of the rotary cylinder 10 and the displacement of the three-axis displacement platform 20 in the PLC controller, the receiving box can be automatically and accurately delivered to the production equipment; by setting the system in the PLC controller, the delivery mechanism can also take the receiving box out of the production equipment and place it on the collection table next to it. Therefore, the present invention can completely replace manual labor, which increases the delivery speed of the receiving box and saves the labor cost of the enterprise.

[0024] Embodiment 2

[0025] The receiving box is placed in the base, and most of the box body is immersed in the cutting fluid. The handle on the outside of the box body may also be immersed in the cutting fluid. Although the production equipment is in a shutdown state when the receiving box is replaced, the cutting fluid will continue to flow out of the liquid pipe next to the tool. Therefore, the pneumatic part of the pneumatic clamp 30 is best not to enter the production equipment.

[0026] See also Figure 2 The pneumatic clamp 30 includes a fixed plate 31, two cylinders 32 arranged opposite to each other, and two clamps 33. The fixed plate is fixedly connected to the top turntable of the rotating cylinder 10, and the two clamps are respectively fixedly connected to the outer telescopic rods of the two cylinders. When the telescopic rods of the two cylinders extend outward, the two clamps open outward, and when the telescopic rods of the two cylinders retract inward, the two clamps gather inward. An L-shaped hook plate 34 extending downward and winding away from the cylinder is installed at the bottom of each clamp, so that the pneumatic part of the pneumatic clamp 30 can be prevented from entering the cutting fluid.

[0027] See also Figure 3A hook block 35 and a spring block 36 are arranged on the inner side of the L-shaped hook plate. The spring block is located above the hook block. The spring is fixed to the hook plate through a spring 37. When the spring is not compressed, the distance between the spring block and the hook block is less than the clamping thickness of the external handle of the receiving box. The telescopic rods of the two cylinders are retracted inward, and the handle of the receiving box is pressed between the hook block and the spring block. The spring block is pressed tightly against the top of the handle under the action of the spring to prevent the receiving box from falling off from the pneumatic clamp 30 during the transfer process.

[0028] See also Figure 4 A V-shaped guide opening 38 is provided on one side of the spring block and the hook block relative to the hook plate, so that the handle of the receiving box can enter between the hook block and the spring block.

[0029] Embodiment 3

[0030] The base is generally provided with a boss, and the bottom of the receiving box is provided with a slot. The receiving box is lowered into the base, and the boss is inserted into the slot. After the pneumatic clamp 30 releases the receiving box, the pneumatic pressure block 40 presses the receiving box tightly into the base.

[0031] See also Figure 5 The pneumatic pressing block 40 includes a lifting cylinder 41, a bottom plate 42 and four pressing blocks 43. The cylinder body of the lifting cylinder is fixed to the top of the turntable of the rotary cylinder 10, the bottom plate is installed at the bottom of the telescopic rod of the lifting cylinder, and the four pressing blocks are installed at the bottom of the bottom plate by connecting rods 44. The four pressing blocks press the receiving box at the same time to prevent the receiving box from deformation and ensure that the receiving box is horizontally clamped on the base.

[0032] The pressing block is installed by connecting rod, which can prevent the bottom plate from contacting the cutting fluid. A plurality of through holes 45 are provided in the pressing block, which can reduce the weight of the pressing block and reduce the resistance of the cutting fluid.

[0033] The pressing block is installed by a connecting rod, which can prevent the bottom plate from contacting the cutting fluid. A plurality of through holes are arranged in the pressing block, which can reduce the weight of the pressing block and reduce the resistance of the cutting fluid.
