However, the clamping of the workpiece currently relies entirely on the operator to clamp it manually, which also makes it easy for the machining axis of the multi-step hole 101 to be not parallel to the X-axis and the machining axis of the two air outlet holes 102 to be not parallel to the Z-axis after the workpiece is clamped, making the machining surfaces of the two air outlet holes 102 and the multi-step hole 101 not meet the requirements, making the valve body 10 easily scrapped, and having the defect of too high a defective product rate. Utility Model Content

[0004] In order to solve the technical problem of high defective rate in the processing of compact ABS integrated valves, the present application provides an automated milling device for compact ABS integrated valves.

[0005] The present application provides a compact ABS integrated valve automated milling device that adopts the following technical solution:

[0006] A compact ABS integrated valve automated milling equipment comprises a machine body, on which are provided a milling cutter for processing a valve body and a movable seat, on which are provided a cradle turntable and a mounting plate, on which is rotatably connected a rotating head, on which is also provided a driving assembly for driving the rotating head to rotate, on which is provided a mounting plate on the rotating head, on which is provided a fixed block for placing the valve body, on which is also provided a pressing portion for pressing the valve body against the fixed block, and on which is also provided a limiting assembly for limiting the placement direction and position of the valve body on the fixed block.

[0007] By adopting the above technical solution, when it is necessary to mill the air inlet and multi-step holes of the valve body, the valve body is first manually picked up and placed on the fixed block, and the limiting assembly is used to ensure that the placement direction and position of the valve body meet the requirements, and then the valve body is pressed against the fixed block using a pressing block to ensure the stability of the valve body during processing.

[0008] Preferably, the limit assembly includes a first limit pin provided on the fixed block for plugging and cooperating with the air inlet hole, a second limit pin provided on the fixed block for plugging and cooperating with the assembly hole, and a third limit pin provided on the mounting plate, wherein a third reference surface is provided on the top of the third limit pin for fitting with the second reference surface.

[0009] By adopting the above technical solution, when it is necessary to mill the air inlet and the multi-step hole of the valve body, the worker picks up the valve body with the second reference surface of the valve body facing the bottom surface, and then places the valve body on the mounting plate and aligns the air inlet and assembly hole of the valve body with the first limit pin and the second limit pin respectively, and the third limit pin is located between the mounting plate and the valve body. Then push the valve body so that the first limit pin is inserted into the air inlet hole, the second limit pin is inserted into one of the assembly holes, and finally the valve body will be against the first limit pin and the second limit pin, and the second reference surface will fit with the third reference surface. At this time, the axis of the air inlet hole and the axes of several assembly holes are parallel to the Y-axis, the processing axis of the multi-step hole is parallel to the X-axis, and the processing axis of the two air outlet holes is parallel to the Z-axis. Then use the pressing part to press the valve body against the first limit pin and the second limit pin to ensure the stability of the valve body during milling, and then start the machine so that the milling cutter first mills the two air outlet holes. After the two air outlet holes are processed, the driving assembly drives the rotating head to rotate 90 degrees so that the mounting plate, valve body and other components rotate 90 degrees. After the valve body rotates, the axes of the two air outlet holes are parallel to the X-axis, and the axes of the multi-step hole are parallel to the Z-axis. Then the milling cutter mills the multi-step hole.

[0010] Preferably, the pressing portion includes a slide arranged on the bottom plate, a pressing block slidably connected to the slide along the Y-axis direction, and a driving member for driving the pressing block to move, and the first limit pin is located on the moving path of the pressing block.

[0012] Preferably, the driving member is an oil cylinder, and the output shaft of the oil cylinder is connected to the pressure block.

[0013] By adopting the above technical solution, the oil cylinder can provide a stable pressing force for the pressing block to press the valve body. After the operator places the valve body, the oil cylinder can be actively started to extend the output shaft of the oil cylinder so that the pressing block presses the valve body against the first reference plane.

[0014] Preferably, a rubber pad is provided on one end of the pressing block facing the fixing block.

[0015] By adopting the above technical solution, the provision of the rubber pad enables the pressing block to play a certain protective role on the valve body when pressing the valve body.

[0016] Preferably, a plurality of second rubber pads are provided on the fixing block, and when the pressing portion fixes the valve body on the first limit pin and the second limit pin, the plurality of second rubber pads are in conflict with the first reference surface.

[0017] By adopting the above technical solution, the provision of multiple second rubber pads reduces the interaction force between the valve body and the first limit pin and the second limit pin when the valve body is fixed, thereby effectively reducing the possibility of wear at the joint between the valve body and the first limit pin and the second limit pin.

[0018] Preferably, the mounting plate is connected to the rotating head via bolts, and a plurality of lifting rings are provided on the mounting plate.

[0019] By adopting the above technical solution, the chip removal groove is arranged so that when the workpiece surface is cleaned with an air gun after the workpiece is milled, the machining debris in the assembly hole can be removed through the chip removal groove.

The limiting assembly 15 includes a first limiting pin 4 fixed on the fixing block 3 for plugging and matching with the air inlet hole 103, a second limiting pin 5 fixed on the fixing block 3 for plugging and matching with the assembly hole 104, and a third limiting pin 6 fixed on the mounting plate 2. The top of the third limiting pin 6 is provided with a third reference surface 61 for fitting with the second reference surface 106. When the body 1 is not started, the axes of the first limiting pin 4 and the second limiting pin 5 are parallel to the Y axis, and the axis of the third limiting pin 6 is parallel to the Z axis.

[0036] Reference Figure 4-Figure 6 , a plurality of second rubber pads 9 are provided on the fixed block 3.

[0037] Reference Figure 1-Figure 6 The specific clamping processing steps of the valve body 10 of the present application are as follows:

[0038] When it is necessary to perform milling on the air inlet and the multi-step stepped hole 101 of the valve body 10, firstly, the valve body 10 is manually picked up with the second reference surface 106 of the valve body 10 facing the bottom surface, and then the valve body 10 is placed on the mounting plate 2 with the air inlet 103 and the assembly hole 104 of the valve body 10 aligned with the first limit pin 4 and the second limit pin 5 respectively, and the third limit pin 6 is located between the mounting plate 2 and the valve body 10.
