Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic drill changing, and particularly relates to an automatic drill changing mechanism. BACKGROUND

[0002] China's high-speed railway has formed a high-speed railway network that is connected everywhere after high-speed development for more than ten years. When the high-speed railway is constructed, high-speed railway bridges often need to be erected. The high-speed railway bridge adopts a cement reinforced pouring crash barrier. The crash barrier is about 20 cm thick and about 70 cm high. Within an average range of about 450 meters, 5-6 signal devices need to be installed. Each device needs to punch 4 mounting holes on the crash barrier. The sizes of the mounting holes are different, and when different holes need to be punched, the current mode is to manually hold a drill bit to punch holes. When the drill bit needs to be changed, a wrench is used to tighten and loosen the drill bit and the drill machine, which is not only laborious but also time-consuming.

The guide rail is disposed on the fixed connecting device along the vertical direction of the fixed connecting device; the lead screw is movably disposed on the guide rail to move along the guide rail.

[0012] In the preferred embodiment of the above-mentioned automatic drill changing mechanism, the linkage actuator further includes: a sensing device, which is communicatively connected to the drive device and the lifting device, and is used to control the lifting device to move the linkage actuator into position and control the drive device to work.

[0013] In the preferred embodiment of the above-mentioned automatic drill bit changing mechanism, the fixed drill bit storage includes: a bracket base plate, which is used to place the automatic drill bit to be changed.

[0014] In the preferred embodiment of the above-mentioned automatic drill bit changing mechanism, there are multiple bracket seats, which are arranged in parallel on the fixed connection device for placing different automatic drill bits to be changed.

[0015] In the preferred embodiment of the above-mentioned automatic drill bit changing mechanism, the fixed connection device includes a fixed connection plate, a quick-change upper baffle, and a quick-change insert side plate, wherein the reserve fixed drill bit magazine and the linkage actuator are disposed on the fixed connection plate, and the fixed connection plate, the quick-change upper baffle, and the quick-change insert side plate together are used to cover the reserve fixed drill bit magazine.

[0036] Figure 1 A schematic diagram of an automatic drill changing mechanism provided by the present invention is shown;Figure 2 Another schematic diagram of an automatic drill changing mechanism provided by the present invention is shown.

[0037] like Figures 1 to 2 As shown, an embodiment of this disclosure provides an automatic drill bit changing mechanism. The automatic drill bit changing mechanism includes a fixed connection device 1, a fixed drill bit storage magazine 2, a quick-change docking device 3, and a linkage actuator 4. The fixed drill bit storage magazine 2 is disposed on the fixed connection device 1, and an automatic drill bit 5 is disposed within the fixed connection device 1. The quick-change docking device 3 is connected to the automatic drill bit 5. The linkage actuator 4 is disposed on the fixed connection device 1 and, in cooperation with the quick-change docking device 3, enables the rapid connection of the automatic drill bit 5 to the drilling rig equipment.

[0038] Specifically, to facilitate rapid drill bit replacement for drilling rigs, this application designs an automatic drill bit changing mechanism. The fixed connection device 1 provides a platform for securing other devices. The fixed connection device 1 can be a fixed plate or block, or other structure that allows for easy connection and fixation. The storage fixed drill bit magazine 2 temporarily holds multiple automatic drill bits 5, providing sufficient space for each bit without causing interference during replacement. The automatic drill bits 5 can be movably placed within the storage fixed drill bit magazine 2. A quick-change docking device 3 is connected to one end of each automatic drill bit 5, with each automatic drill bit 5 connected to one quick-change docking device 3, enabling rapid connection of the automatic drill bit 5 to the drilling rig.

[0039] The automatic drill bit changing mechanism, by setting up a quick-change docking device 3 and a linkage actuator 4, can automatically control the automatic drill bit 5 to be replaced in the fixed drill bit storage 2 to be automatically separated from it and quickly replaced when the drilling rig needs to change drill bits.

[0040] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the quick-change docking device 3 includes a quick-change male connector 31 and a quick-change female connector 32 that are docked together, wherein the quick-change male connector 31 is connected to the automatic drill bit 5.

[0041] Specifically, the quick-change male connector 31 and quick-change female connector 32 are a pair of quick-change connectors that mate together. The quick-change male connector 31 is connected to the automatic drill bit 5, forming a unified replacement component with the automatic drill bit 5, and is subsequently connected together with the automatic drill bit 5 to the quick-change female connector on the drilling rig equipment to complete the quick drill bit change. The quick-change female connector 32 has built-in steel balls, which achieve self-locking when the quick-change male connector 31 and quick-change female connector 32 are mated, making separation and engagement convenient and effortless.

[0042] In particular, Figure 1At the bottom is shown an automatic drill bit 5, and the four long bars above it are schematic representations of the automatic drill bit 5. They are shown as long bars for the sake of layout in the diagram and to avoid affecting the observation of other components.

[0043] like Figures 1 to 2 As shown, in the preferred technical solution of this application, the linkage actuator 4 includes a drive device 41 and a push device 42. One end of the push device 42 is connected to the output end of the drive device 41 so as to push the quick-change female connector 32 and the quick-change male connector 31 to separate under the drive of the drive device 41.

[0044] Specifically, the linkage actuator 4 includes two parts: a drive device 41 for providing power and a push device 42 that can move back and forth under the action of the drive device 41. When determining which automatic drill bit 5 to replace, the quick-change female connector 32 and quick-change male connector 31 in the quick-change docking device 3 connected to the automatic drill bit 5 are separated, thereby enabling the automatic drill bit 5 and the quick-change male connector 31 connected to it to be used together.

[0045] Preferably, the drive device 41 can be a motor.

[0046] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the pushing device 42 includes a cam 421, a quick-change push plate 422, and a wedge 423. One end of the cam 421 is connected to the output end of the driving device 41, and the other end is connected to one end of the quick-change push plate 422. The other end of the quick-change push plate 422 is connected to the wedge 423, so as to convert the rotational motion of the output end of the driving device 41 into the back-and-forth motion of the wedge 423.

[0047] Specifically, after the drive device 41 is started, it outputs rotational motion through its output end. Since one end of the cam 421 is connected to the output end of the drive device 41, the cam 421 moves back and forth under the action of the rotational motion of the output end of the drive device 41. The quick-change push plate 422 is a rectangular plate-shaped object or a long rod-shaped object, which also moves back and forth under the drive of the cam 421. A wedge block 423 is also connected to the other end of the quick-change push plate 422. Similarly, the wedge block 423 can move back and forth. Thus, the wedge block 423 can push the quick-change female connector 32 and the quick-change male connector 31 to separate.

[0048] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the linkage actuator 4 further includes a lifting device, which is mounted on the fixed connection device 1 and connected to the pushing device 42 and the driving device 41, for moving the pushing device 42 and the driving device 41 up and down.

[0049] Specifically, another important component of the linkage actuator 4 is the lifting device. This lifting device enables the pushing device 42 and the driving device 41 to move up and down along the fixed connection device 1 as a whole. In a specific example, the automatic drill bit 5 is arranged parallel to the vertical direction of the fixed connection device 1. This allows different models of automatic drill bits 5 to be located at different heights. Thus, driven by the lifting device, the pushing device 42 and the driving device 41 can move to the positions of different automatic drill bits 5 at different heights, separating the quick-change male connector 31 and quick-change female connector 32 connected to them.

[0050] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the lifting device includes a guide rail and a lead screw. The guide rail is disposed on the fixed connection device 1 along the vertical direction of the fixed connection device 1. The lead screw is movably disposed on the guide rail to move along the guide rail.

[0051] Specifically, the guide rail combined with the lead screw is a concrete implementation of the lifting device. The guide rail is arranged along the vertical direction of the fixed connection device 1, thereby facilitating the vertical movement of the push device 42 and the drive device 41. The lead screw plays a cooperating role, enabling smooth vertical movement.

[0052] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the linkage actuator 4 further includes a sensing device, which is communicatively connected to the drive device 41 and the lifting device, and is used to control the lifting device to move the linkage actuator 4 into position and control the drive device 41 to work.

[0053] Specifically, the sensing device can be a sensing module with various sensing functions. For example, a radar sensing module or an infrared sensing module with moving target detection capabilities. Simultaneously, the sensing device can also include a control module for monitoring after detecting a target and issuing control commands to control other components to move in coordination. Here, "the linkage actuator 4 moving to position" means that the linkage actuator 4 moves to the quick-connect female connector 32 that needs to be pushed.

[0054] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the fixed drill bit storage 2 includes a bracket base plate 21, which is used to place the automatic drill bit 5 to be replaced.

[0055] Specifically, the bracket base 21 can be, for example, a row of support bodies. The support body is a concave bracket, and the interior of the concave bracket has a semi-circular structure to facilitate the placement of the automatic drill bit 5. The number of these support bodies can be three or more arranged side-by-side to securely support the drill bit 5. This also reduces the floor space occupied by the bracket base 21, saving space.

[0056] Specifically, the fixed drill bit storage 2 contains drill bits for the required drilling process, is made of lightweight materials, and is driven by a motor to achieve precise drill bit positioning.

[0057] like Figures 1 to 2 As shown, in the preferred embodiment of this application, there are multiple bracket seats 21, which are arranged in parallel on the fixed connection device 1 for placing different automatic drill bits 5.

[0058] Specifically, the automatic replaceable drill bits 5 come in different models, and there are several commonly used models. Therefore, the fixed drill bit storage 2 needs to prepare multiple automatic replaceable drill bits 5. Moreover, in order to facilitate the replacement of the automatic replaceable drill bits 5 and to avoid conflicts between them, the multiple bracket base plates 21 are preferably arranged in parallel on the fixed connection device 1.

[0059] like Figures 1 to 2 As shown, in the preferred embodiment of this application, the fixed connection device 1 includes a fixed connection plate 11, a quick-change upper baffle 12, and a quick-change insert side plate 13. The fixed drill bit magazine 2 and the linkage actuator 4 are disposed on the fixed connection plate 11. The fixed connection plate 11, the quick-change upper baffle 12, and the quick-change insert side plate 13 together are used to cover the fixed drill bit magazine 2.

[0060] Specifically, the fixed connecting plate 11 can be a rectangular or square thin plate. A quick-change insert side plate 13, perpendicular to the fixed connecting plate 11, is connected to one side of the fixed connecting plate 11. This quick-change insert side plate 13 is narrower than the fixed connecting plate 11 and mainly serves as a protective barrier. A quick-change upper baffle 12 is provided on the upper side of the fixed connecting plate 11 and the quick-change insert side plate 13, which, together with the fixed connecting plate 11 and the quick-change insert side plate 13, is used to enclose the fixed drill bit magazine 2.

[0061] In a preferred embodiment, when a drill bit needs to be changed, the diameter parameter of the automatic drill bit 5 to be replaced is input on the control platform. After the drilling rig reaches the position of the automatic drill bit changing mechanism, the lifting device in the linkage actuator 4 drives the pushing device 42 and the driving device 41 to rise or fall to the corresponding position of the drill bit to be replaced. The driving device 41, for example, is a motor that drives the cam 421 to move, and the movement of the cam 421 pushes the quick-change push plate 422 to move, thereby ultimately driving the wedge block 423 to move. After the forward movement of the wedge block 423 pushes open the outer ring of the quick-change female connector 32, the quick-change male connector 31 separates from the quick-change female connector 32. At this time, the quick-change female connector on the drilling rig quickly connects with the quick-change male connector 31 of the automatic drill bit changing mechanism, and the drill bit installation is completed. The drilling rig moves to the designated location to drill according to instructions. When a drill bit change is needed, the rig first removes the installed drill bit and places it in the corresponding position on the empty bracket plate 21 in the fixed drill bit storage. After the rig leaves, it moves to the position where the drill bit needs to be installed and mates with it. The motor drives the cam 421, which in turn causes the linkage actuator 4 to push open the outer ring of the quick-change female connector 32, allowing the quick-change male connector 31 to be quickly disassembled. The quick-change female connector 32 of the drilling rig then mates with the quick-change male connector 31. This mechanism uses only one motor to drive automatic drill bit changing, reducing energy consumption and weight.

[0062] In a preferred embodiment, the fixed connecting plate 11 is a rectangular plate structure, its length being longer than the length of the automatic drill bit 5 and its height being longer than the height of the multiple automatic drill bits 5 arranged side by side. The fixed connecting plate 11, the quick-change upper baffle 12, and the quick-change insert side plate 13 are of the same height. The three together enclose the storage fixed drill bit magazine 2. The storage fixed drill bit magazine is provided with multiple rows of bracket seats 21 arranged side by side, wherein each bracket seat 21 includes 5 concave supports. The concave supports have a semi-circular structure inside, which can just partially enclose and support the automatic drill bits 5.

[0063] The automatic drill bit changing mechanism of this application, by setting up a quick-change docking device 3 and a linkage actuator 4, can automatically control the automatic drill bit to be replaced in the fixed drill bit storage 2 to be automatically separated from it and quickly replaced when the drilling equipment needs to change the drill bit.

[0064] The quick-change docking device 3 uses a quick-change male connector 31 and a quick-change female connector 32 that are docked together. The quick-change male connector 31 is connected to the automatic drill bit 5. The quick-change male connector 31 and the quick-change female connector 32 are pushed apart by the driving device 41 through the pushing device 42 composed of cam 421, quick-change push plate 422 and wedge block 423. The drilling equipment is also equipped with a quick-change female connector, so that when it is necessary to change the drill bit, the quick-change female connector on the drilling equipment is docked with the quick-change male connector 31 after the quick-change female connector 32 is separated on the automatic drill bit 5, so as to realize automatic and quick drill bit replacement.

[0065] The lifting device using a combination of guide rail and lead screw in this application can move along the vertical direction of the fixed connection device 1, thereby driving the linkage actuator 4 to move up and down to the automatic drill bit 5 that needs to be replaced, with rapid and precise movement.
