[0002] Bathrooms are spaces and supplies for daily public health activities such as defecation, bathing, and washing. Various bathroom equipment, such as faucet seats, are installed in bathrooms. Traditional faucet seats have always been processed by multiple machines in different processes, which has the disadvantages of occupying many equipment, manpower, and plant areas, as well as many scratches and bruises during transportation between processes, resulting in high manufacturing costs and low efficiency. Summary of the invention

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for automatically processing a faucet seat comprises the following steps:

[0006] Step 1: Before use, check whether the pneumatic system and hydraulic system of the device are normal, check whether the pipes and lines of each system are connected correctly, and detect the temperature and humidity of the surrounding environment;

[0007] Step 2: If the pneumatic system and hydraulic system of the device are normal, the pipes and lines of each system are correctly connected, the temperature of the surrounding environment is detected to be 0°C-60°C, and the humidity of the surrounding environment is detected to be 40%-100%, then the workpiece to be processed is placed at the loading station of the turntable;

[0008] Step 3: After the workpiece is placed, press the mold closing button of the loading station to clamp the workpiece with the clamp on it;

[0009] Step 4: After the workpiece is clamped, it is transferred to the boring station to blow the chips off the workpiece. After the chips are blown off, the positive mold device is activated to calibrate the workpiece. Then the pneumatic pressure head is activated to press the workpiece. Then the boring power head is activated, and the boring tool on it is fed to the workpiece to bore the hole. After completion, the boring tool is reset.

[0010] Step 5: After the boring is completed, the workpiece is transferred to the boring lower end face station, and the workpiece is swarfed. After the swarf blowing is completed, the internal expansion positioning device on the boring lower end face station is actuated to mechanically position the workpiece. After positioning, the translation clamping head on the boring lower end face station is actuated to press the workpiece to the internal expansion head for positioning, and then the internal expansion head expands and fixes the workpiece. After fixing, the translation clamping head releases the workpiece and resets it. Then, the boring lower end face power head works, and the boring lower end cutter on it feeds the workpiece to bore the lower end face. After completion, the boring lower end cutter is reset, and the internal expansion head is released and reset.

[0011] Step 6: After the lower end face is bored, the workpiece is transferred to the upper end face boring station, and the workpiece is blown. After the chip blowing is completed, the inner expansion positioning device on the upper end face boring station is actuated to mechanically position the workpiece. After positioning, the translation clamping head on the upper end face boring station presses the workpiece to the inner expansion head for positioning, and then the inner expansion head expands and fixes the workpiece. After fixing, the translation clamping head releases the workpiece and resets it. Then, the upper end face boring power head works, and the upper end boring tool on it feeds the workpiece to bore the upper end face. After completion, the upper end boring tool is reset, and the inner expansion head is released and reset.

[0012] Step 7. After the upper end surface is bored, the workpiece is transferred to the unloading station, and the processed workpiece is removed for chip blowing and cleaning.

[0013] This device adopts the form of a three-axis disc machine, integrating the three processes of boring holes, boring upper end faces and boring lower end faces into one machine. It only needs one person to operate and clamp once, avoiding the problem of inaccurate positioning caused by multiple clamping, reducing intermediate transportation and problems such as bumps, pinching and scratches, reducing the occupied plant area by more than half, reducing the number of operators, significantly reducing manufacturing costs, and significantly improving production efficiency.

The pressure oil in the oil distribution tank 27 is sequentially passed through the valve body, pipeline, oil inlet 38 and channel 39 to the fixed block slide 41. The control slide rod 40 moves in the fixed block slide 41 to clamp the workpiece. After completion, the workpiece is transferred to the bottom of the boring assembly.

[0062] 2. When the workpiece is transferred to the bottom of the boring assembly, the oil cylinder 21 is actuated to drive the limit block 22 to move upward, and the workpiece mounting groove 23 is moved to the bottom of the workpiece for assembly. Then the air cylinder 25 is actuated to drive the pressure head 24 to move downward to press the workpiece. After pressing, the boring power head 3 drives the tool 4 to work, pass through the pressure head through hole 43, and bore the workpiece. After completion, the oil cylinder 21, the air cylinder 25 and the boring power head 3 are reset, and the workpiece is transferred to the bottom of the boring lower end face assembly.

[0063] 3. When the workpiece is rotated to the bottom of the boring lower end face assembly, the oil cylinder 29 is activated to drive the mounting block 30 to move downward, so that the inner expansion head assembly 17 on the mounting block 30 moves to the vicinity of the workpiece, and then the lower fixed plate 33 moves to the right below the workpiece, and the cylinder 2 32 works to drive the movable pressing plate 31 to move upward, pressing the workpiece into the inner expansion head groove 54, and then the pressure oil in the oil supply tank 44 flows into the annular cavity 49 through the oil outlet 47, the oil inlet hole 46 and the connecting channel 48 in turn, exerting pressure on the sliding sleeve 51 so that the sliding sleeve 51 moves toward the pressing block 5 5 moves and applies pressure to the pressing block 55.

The radial force of the pressing block 55 presses the workpiece to fix it in the inner expansion head groove 54. After fixation, the moving pressing plate 1 31 and the lower fixing plate 2 33 are reset to make way for the boring tool. Then the boring lower end face power head 35 drives the tool 2 36 to work and bore the lower end face of the workpiece.
