Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining equipment technology, and in particular to a fully automatic block drilling and tapping machine. Background Technology
[0002] In modern machining, drilling and tapping are the most common and critical machining processes in the manufacture of metal parts. Traditional machining methods typically require these processes to be completed on different equipment; for example, drilling is done on a drilling machine first, and then tapping is done on a tapping machine. This decentralized machining model has many drawbacks. First, frequent equipment changes lead to low machining efficiency. Each equipment change requires re-clamping the workpiece and adjusting machining parameters, increasing auxiliary time and reducing production efficiency. Second, multiple clamping can easily cause workpiece positioning errors, affecting machining accuracy. It is difficult to guarantee the consistency of machining accuracy between different machines, which in turn affects the overall quality of the parts. In addition, multi-machine processing increases the equipment footprint and investment costs. For enterprises, this not only requires purchasing multiple machines but also equipping them with corresponding operators and maintenance personnel, significantly increasing labor and equipment maintenance costs.

[0045] refer to Figures 1-9 This embodiment provides a fully automatic block drilling and tapping machine, including a frame 10 and a feeding device 2, a loading device 3, a pre-drilling device 4, a drilling device 5, a chamfering device 6, a tapping device 7, a detection device 8, an unloading device 9, and a control system 101 for controlling the processing of each device, all mounted on the frame 10. By integrating functions such as pre-drilling, drilling, chamfering, tapping, and detection, and with automatic loading and unloading, efficient and automated processing is achieved, improving processing efficiency and quality.
[0046] like Figure 1 The frame 10 is equipped with a turntable 1, and a plurality of processing positions 11 are evenly distributed along the circumference of the turntable 1. Each processing position 11 includes a first fixture 12, which is used to place a workpiece 102. The turntable 1 is used to transfer the workpiece 102 between different devices. The turntable 1 is equipped with a clamping device 13, and a set of clamping devices 13 is set for each first fixture 12. The clamping device 13 is used to clamp and fix the workpiece 102 on the first fixture 12. The workpiece 102 includes a processing hole 1021. The pre-drilling device 4, drilling device 5, chamfering device 6, and tapping device 7 are used to process the processing hole 1021. The feeding device 3, pre-drilling device 4, drilling device 5, chamfering device 6, tapping device 7, detection device 8, and unloading device 9 are arranged sequentially along the rotation direction of the turntable 1. The feeding device 2 is connected to the feeding device 3.
[0047] The frame 10 serves as the basic framework of the equipment, supporting all processing devices and the control system 101. The turntable 1 includes a rotating device, which drives the turntable 1 to transport the workpiece 102 and switch between different processing steps. The first tooling 12 is used to carry the workpiece 102 and transfer it to various devices for processing.
[0048] The pre-drilling device 4 is used for pre-drilling the machining hole 1021 on the workpiece 102, and works in conjunction with the drilling device 5 to complete the drilling process of the machining hole 1021. Both the pre-drilling device 4 and the drilling device 5 include a drilling power head for the drilling process, and the drilling direction is from top to bottom, starting from the top surface of the machining hole 1021. The chamfering device 6 includes a chamfering power head, which is located below the turntable 1, and its chamfering direction is from bottom to top, performing a chamfering process on the bottom surface of the machining hole 1021 on the workpiece 102. The tapping device 7 includes a tapping power head for completing thread processing, and its tapping direction is from top to bottom, starting from the top surface of the machining hole 1021. The detection device 8 includes a contact sensor 323 (such as a probe), which is driven by a lifting device to measure the machining status of the machining hole 1021 on the workpiece 102.
[0049] The control system 101 employs a PLC or CNC system to achieve automated control of the equipment and adjustment of processing parameters. Position sensors 323 are installed on each device to identify whether the processing position 11 has rotated into position when the turntable 1 rotates to switch processing positions 11, thus enabling the corresponding device to be driven for processing.
[0050] like Figure 2 The specific structure of the turntable 1 is as follows: the turntable 1 has several processing positions 11 evenly distributed along its circumference; each processing position 11 is provided with a first tooling 12; each first tooling 12 is provided with at least one placement slot 121, preferably two placement slots 121 on the first tooling 12. Figure 3 Each of the placement slots 121 includes a first opening 122 arranged radially outward, and a second opening 123 and a third opening 124 arranged vertically. The second opening 123 is located at the top of the placement slot 121, and the third opening 124 is located at the bottom of the placement slot 121. The workpiece 102 is placed in or removed from the placement slot 121 through the first opening 122. The pre-drilling device 4, the drilling device 5, and the tapping device 7 all perform machining on the machining hole 1021 vertically from top to bottom through the second opening 123. The chamfering device 6 performs machining on the machining hole 1021 vertically from bottom to top through the third opening 124.
[0051] like Figure 2The specific structure of the clamping device 13 is as follows: the clamping device 13 includes a connecting rod 131 and a pressure block 132. The connecting rod 131 is located below the turntable 1, and the pressure block 132 is located above the first tooling 12. One end of the connecting rod 131 passes vertically from bottom to top through the turntable 1 and the first tooling 12 and is connected to the pressure block 132. The other end of the connecting rod 131 is connected to a push block 133. The connecting rod 131 is movable vertically relative to the turntable 1 and the first tooling 12. An elastic element 134 is fitted onto the rod body of the connecting rod 131, and the two ends of the elastic element 134 are respectively connected to the turntable 1 and the push block 133. When the workpiece 102 is pressed, the elastic element 134 pushes the push block 133 vertically downward, so that the connecting rod 131 drives the pressing block 132 vertically downward. The pressing block 132 presses down onto the placement groove 121 to press and fix the workpiece 102 in the placement groove 121 vertically, ensuring that the workpiece 102 does not shift during the processing.
[0052] like Figure 3 The pressure block 132 is provided with a pressure head 1321 corresponding to the second opening 123 of the placement groove 121. The pressure head 1321 is pressed into the placement groove 121 through the second opening 123 and presses down on the workpiece 102. The pressure head 1321 includes a notch 1322, which is used to expose the machining hole 1021. The notch 1322 creates clearance, ensuring that the machining process of the machining hole 1021 is not affected after the workpiece 102 is fixed, and avoiding interference between the machining power head and the pressure head 1321.
[0053] like Figure 4 The specific structure of the release device 14 is as follows: a release device 14 is provided below the turntable 1 corresponding to the pressing device 13. The release device 14 includes a first lifting cylinder 141 and a pressure plate 142. The lifting cylinder drives the pressure plate 142 to move vertically up and down. When releasing the workpiece 102, the lifting cylinder is activated, and the pressure plate 142 is used to lift the push block 133 vertically upward. The push block 133 squeezes the elastic element 134 and pushes the connecting rod 131 upward, so that the connecting rod 131 lifts the pressure block 132 upward. The pressure block 132 disengages from the placement groove 121, and the workpiece 102 is released vertically.
[0054] In this embodiment, the pressure block 132 only needs to be released during loading and unloading. Therefore, a set of release devices 14 are respectively provided in the loading device 3 and the unloading device 9. When the pressure block 132 is lifted and removed from the placement groove 121, the loading device 3 or the unloading device 9 can place or remove the workpiece 102 from the placement groove 121 through the first opening 122.
[0055] The clamping device 13 provides pressure through the elastic element 134, which fixes the workpiece 102. In the initial state, the clamping block 132 of the clamping device 13 is always pressed into the placement groove 121 under the action of the elastic element 134. Therefore, during loading, the clamping block 132 needs to be released and lifted upward to release the space in the placement groove 121, so that the workpiece 102 can be smoothly placed into the placement groove 121. Therefore, a set of release devices 14 needs to be set for the loading device 3. During unloading, the clamping block 132 needs to be lifted to release the workpiece 102, so that the workpiece 102 can be smoothly removed from the placement groove 121, completing the unloading.
[0056] like Figure 5 The specific structure of the unloading device 9 is as follows: the unloading device 9 includes an unloading channel 91, an unloading pusher 92 and a drive module 93. The drive module 93 includes a radial drive group 931 and a vertical drive group 932, which are used to drive the unloading pusher 92 to move radially and vertically, respectively. The unloading pusher 92 picks up the workpiece 102 vertically downward and transports the workpiece 102 radially outward to the unloading channel 91.
[0057] The unloading pusher 92 includes a rod 921, which can be inserted vertically downward into the machining hole 1021. When the rod 921 is inserted into the machining hole 1021, the radial drive group 931 drives the unloading pusher 92 to push the workpiece 102 out of the placement groove 121 through the rod 921.
[0058] The unloading operation of the unloading device 9 is as follows: when the turntable 1 rotates and the processing position 11 rotates to the position of the discharge channel 91, the radial drive group 931 drives the unloading pusher 92 to move radially inward until the insertion rod 921 corresponds to the position of the processing hole 1021. Then, the vertical drive group 932 drives the unloading pusher 92 to move vertically downward and insert the insertion rod 921 into the processing hole 1021. At the same time, the release device 14 drives the pressure plate 142 to act on the connecting rod 131 to lift the pressure block 132 upward and separate it from the workpiece 102. After the workpiece 102 is released, the radial drive group 931 drives the unloading pusher 92 to move radially outward. The insertion rod 921 pushes the workpiece 102 away from the placement hole and lowers it into the discharge channel 91, thus completing the unloading of the workpiece 102.
[0059] like Figure 6 The feeding device 2 includes a feeding channel 21, which is connected to the loading device 3 via the reverse S-shaped feeding channel 21. The feeding device 2 includes a vibrating plate 22, which vibrates and transports the workpiece 102 to the loading device 3.
[0060] like Figure 7 , Figure 8The specific structure of the feeding device 3 is as follows: the feeding device 3 includes a support frame 31 and a feeding assembly 32 and a feeding pusher 33 mounted on the support frame 31. The feeding assembly 32 can move vertically up and down, and the feeding assembly 32 has a first position and a second position. The feeding pusher 33 is arranged vertically with the feeding channel 21, and the position of the feeding pusher 33 corresponds to the position of the first tooling 12 (e.g., ...). Figure 8 When the feeding component 32 is in the first position, the feeding component 32 is connected to the feeding channel 21 (e.g., Figure 7 The workpiece 102 is transported to the loading assembly 32 by the feeding channel 21. When the loading assembly 32 is in the second position, the loading assembly 32 docks with the first tooling 12, and the workpiece 102 on the loading assembly 32 is pushed onto the first tooling 12 by the loading pusher 33.
[0061] like Figure 8 The feeding assembly 32 includes a second lifting cylinder 321, a second tooling 322, a sensor 323, and a baffle 324. The second lifting cylinder 321 is connected to the second tooling 322 via an inverted U-shaped frame 325. The second lifting cylinder 321 is used to drive the second tooling 322 to move vertically up and down. The second tooling 322 has a first position and a second position. At least one through groove 3221 is provided on the second tooling 322, and two through grooves 3221 are provided corresponding to the placement groove 121 on the first tooling 12. The through grooves 3221 are used to place the workpiece 102.
[0062] The sensor 323 is mounted on the baffle 324 and is used to detect whether the workpiece 102 exists in the through groove 3221. When the second tooling 322 is in the first position, one side of the through groove 3221 is connected to the feeding channel 21, and the other side is blocked by the baffle 324. The sensor 323 corresponds to the position of the channel.
[0063] like Figure 7 The feeding pusher 33 includes a feeding cylinder 331 and a feeding component 332. The feeding cylinder 331 drives the feeding component 332 to move radially so that the feeding component 332 can extend into or exit the through groove 3221. When the second tooling 322 is in the second position, one side of the through groove 3221 corresponds to the feeding component 332, and the other side of the through groove 3221 is connected to the first tooling 12. The feeding cylinder 331 drives the feeding component 332 to push the workpiece 102 toward the first tooling 12.
[0064] The feeding operation of the feeding assembly 32 is as follows: the second lifting cylinder 321 drives the second tooling 322 downward to the first position. One side of the through groove 3221 of the second tooling 322 is connected to the outlet of the feeding channel 21. The workpiece 102 is transported into the channel by the feeding channel 21. The other side of the through groove 3221 is blocked by the baffle 324 to prevent the workpiece 102 from falling out of the through groove 3221 from the other side. When sensor 323 senses that workpiece 102 has been placed in the inverted slot 3221, it feeds back to control system 101 to drive second lifting cylinder 321 to drive second fixture 322 upward until second fixture 322 is in second position. One side opening of slot 322 corresponds to loading component 332, and its other side opening is connected to the first opening 122 of first fixture 12. Loading cylinder 331 drives loading component 332 to move toward placement slot 121, pushing workpiece 102 in slot 3221 onto inverted placement slot 121, thus completing the loading of workpiece 102.
