[0047] refer to Figure 1 This embodiment provides a fully automatic step-hole drilling machine for medium-pressure blocks 1421, including a frame 8 and a feeding device 2, a loading device 3, a step-hole drilling device 4, a drilling device 5, a chamfering device 6, a unloading device 7, and a control system for controlling the processing of each device, all mounted on the frame 8. By integrating functions such as step-hole drilling, drilling, and chamfering, and with automatic loading and unloading, efficient and automated processing is achieved, improving processing efficiency and quality.

[0048] like Figure 2 As shown, a rotating disk 1 is provided on the frame 8, and a plurality of processing positions 11 are evenly distributed along the circumference of the rotating disk 1. Each processing position 11 is provided with a tool 12, which is used to place a workpiece 9. The rotating disk 1 is used to transport the workpiece 9 between different devices. Figure 1 The feeding device 3, the step drilling device 4, the drilling device 5, the chamfering device 6, and the unloading device 7 are arranged sequentially along the rotation direction of the rotating disk 1; the feeding device 3 is connected to the feeding device 2.

[0049] like Figure 3 As shown, the tooling 12 includes at least two first placement slots 13, in which workpieces 9 are placed; the rotating disk 1 is provided with a clamping device 14 and a releasing device 15, and a set of clamping devices 14 is provided for each tooling 12; the clamping device 14 is used to clamp and fix the workpiece 9 on the first placement slot 13, and the releasing device 15 is used to release the clamping device 14 from the workpiece 9 and release the workpiece 9 in the first placement slot 13, which facilitates the loading and unloading of workpiece 9.

[0050] The frame 8 serves as the basic framework of the equipment, supporting all processing devices 12 and the control system. The rotating disk 1 includes a rotating device, which drives the rotating disk 1 to realize the transportation of the workpiece 9 and the switching between different processing steps. The tooling 12 is used to carry the workpiece 9 and transfer the workpiece 9 to various devices for processing.

[0051] The step-hole drilling device 4 is used to drill step-holes in the processing area 91 of the workpiece 9. The drilling device 5 performs subsequent drilling operations. Both the step-hole drilling device 4 and the drilling device 5 include a drilling power head for drilling operations. The drilling direction is from top to bottom, drilling from the top surface of the processing area 91 of the workpiece 9 downwards to form a processing hole 92. The chamfering device 6 includes a chamfering power head. The chamfering device 6 is located below the turntable. Its chamfering direction is from bottom to top, chamfering the bottom surface of the processing hole 92 of the workpiece 9. The control system adopts a PLC or CNC system to realize the automated control of the equipment and the adjustment of processing parameters. Sensors are installed on each device. When the turntable rotates to switch processing positions 11, the sensors are used to identify whether the processing position 11 has rotated into place, so that the corresponding device can be driven to perform processing.

[0052] like Figure 3 As shown, the tooling 12 has the following specific structure: two first placement slots 13 are arranged circumferentially; the first placement slots 13 have a first opening 131 arranged radially outward; and a second opening 132 and a third opening 133 are arranged vertically. The second opening 132 is located at the top of the first placement slot 13, and the third opening 133 is located at the bottom of the first placement slot 13. The workpiece 9 is placed or removed from the first placement slot 13 through the first opening 131. The drilling step hole device 4 and the drilling device 5 process the processing area 91 of the workpiece 9 vertically from top to bottom through the second opening 132. The chamfering device 6 processes the processing area 91 of the workpiece 9 vertically from bottom to top through the third opening 133.

[0053] like Figure 4 As shown, the specific structure of the clamping device 14 is as follows: the clamping device 14 includes a connecting rod 141 and a clamping block 142. The top end of the connecting rod 141 passes vertically through the rotating disk 1 and is connected to the clamping block 142. A push block 143 is provided at the bottom end of the connecting rod 141. An elastic element 144 is fitted onto the body of the connecting rod 141. The elastic element 144 pushes the push block 143 downward, so that the connecting rod 141 drives the clamping block 142 downward vertically until the clamping block 142 presses down on the first placement groove 13, pressing the workpiece 9 vertically into the first placement groove 13, ensuring that the workpiece 9 does not shift during the processing.

[0054] The clamping block 142 has two clamping blocks 1421 positioned corresponding to the two first placement slots 13. The clamping blocks 1421 are used to press against the second opening 132 and hold the workpiece 9 within the first placement slot 13. The clamping block 1421 includes a notch 1422, which exposes the processing area 91 of the workpiece 9. The notch 1422 creates clearance, ensuring that the workpiece 9 is fixed and does not affect the processing steps in the processing area 91, thus avoiding interference between the processing power head and the clamping block 1421.

[0055] like Figure 3 A release device 15 is provided below the rotating disk 1 corresponding to the pressing device 14, such as... Figure 4 As shown, the specific structure of the release device 15 is as follows: the release device 15 includes a lifting cylinder 151 and a push rod 152. The lifting cylinder 151 drives the push rod 152 to move vertically up and down. The push rod 152 can push the push block 143 vertically upward, and the push block 143 squeezes the elastic member 144 to push the connecting rod 141 upward, so that the connecting rod 141 drives the clamping block 142 to disengage from the first placement groove 13, and releases the workpiece 9.

[0056] In this embodiment, the clamping block 142 needs to be released during loading and unloading so that the workpiece 9 can be placed in the first placement groove 13. Therefore, a set of release devices 15 are respectively provided for the loading device 3 and the unloading device 7. When the clamping block 142 is lifted and removed from the placement groove, the loading device 3 or the unloading device 7 can place or remove the workpiece 9 from the first placement groove 13 through the first opening 131.

[0057] The clamping device 14 provides pressure through the elastic element 144, which fixes the workpiece 9. In the initial state, the clamping block 142 of the clamping device 14 is always pressed into the first placement groove 13 under the action of the elastic element 144. Therefore, during loading, the clamping block 142 needs to be released and lifted upward to free up space in the first placement groove 13, so that the workpiece 9 can be smoothly placed into the first placement groove 13. Therefore, a set of release devices 15 needs to be set for the loading device 3. During unloading, the clamping block 142 needs to be lifted to release the workpiece 9, so that the workpiece 9 can be smoothly removed from the placement groove to complete the unloading.

[0058] like Figure 5-7 The specific structure of the feeding device 3 is as follows: the feeding device 3 includes a base 31, a slider 32, a telescopic cylinder 33, and a pushing component 34; the feeding device 2 includes a vibrating plate and a feeding channel 21, and the vibrating plate vibrates and transports the workpiece 9 to the feeding device 3 (e.g., ...). Figure 1The base 31 includes at least two discharge ports 311 and one inlet port 312; the rotating disk 1 rotates to one of the tooling 12 corresponding to the base 31, and the at least two discharge ports 311 are connected to the at least two first placement slots 13; the slider 32 is slidably mounted on the base 31, and the telescopic cylinder 33 is connected to the slider 32, the slider 32 including at least two second placement slots 321; the telescopic cylinder 33 drives the slider 32 to slide, and the slider 32 drives the second placement slots 321 to switch between the discharge ports 311 and the inlet port 312; the second placement slots 321 are connected to the discharge ports 311, and the pusher 34 feeds material to the first placement slot 13; the second placement slots 321 are connected to the inlet port 312, and the feeding channel 21 feeds material to the second placement slots 321.

When the slider 32 is in the first position, the second placement groove 321 on the left side along the length direction connects to the discharge port 311 on the left side. The pusher 34 pushes the workpiece 9 in the second placement groove to the first placement groove 13 to realize the loading of the workpiece 9. The second placement groove 321 on the right side connects to the inlet port 312 to receive the workpiece 9 transported by the feeding channel 21 into the second placement groove 321. When the slider 32 is in the second position, the second placement groove 321 on the right side along the length direction connects to the discharge port 311 on the right side. The pusher 34 pushes the workpiece 9 in the second placement groove to the first placement groove 13 to realize the loading of the workpiece 9. The second placement groove 321 on the left side connects to the inlet port 312 to receive the workpiece 9 transported by the feeding channel 21 into the second placement groove 321.

When the telescopic cylinder 33 drives the sliding motion so that the second placement slot 321 is aligned with the discharge port 311, the workpiece 9 is pushed by the push rod 341. The workpiece 9 is pushed from the discharge port 311 onto the first placement slot 13, completing the loading operation of the workpiece 9. After the push, the push rod 341 is driven by the push cylinder 342 to retract and disengage from the second placement slot 321. The second placement slot 321 is then left empty, allowing for subsequent loading operations to be performed on the inlet 312.

[0061] like Figure 6-7 The base 31 and slider 32 are installed such that the base 31 has a groove 314 along its length, and the slider 32 slides within the groove 314.

The slider 32 includes a cover plate 322, which covers the second placement groove 321 and restricts the workpiece 9 in the height direction. By sensing the position of the slider 32 through the position sensors 35, it is possible to identify whether the slider 32 is in a first position or a second position, facilitating the loading operation of the workpiece 9.
