Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically to a five-station automatic drilling machine. Background Technology

[0002] When processing workpieces, holes need to be made in the workpieces to ensure convenient assembly. When making holes arranged in a ring on a circular workpiece, a multi-station drilling machine is required.

[0003] Existing multi-station drilling machines mainly consist of a processing table, drilling mechanisms installed at each station on the processing table, guide components installed at each drilling mechanism, and a power distribution box installed on the drilling mechanism. When using this type of drilling machine, a circular workpiece is first placed on the processing table, and then the drilling mechanism at each station is activated to achieve the drilling of the circular workpiece. Although existing multi-station drilling machines can achieve the drilling of circular workpieces, each drilling mechanism at each station is equipped with a separate set of guide components. The excessive number of guide components makes the overall size of the drilling machine large, which is not conducive to the efficient drilling of circular workpieces in confined spaces. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a five-station automatic drilling machine that, in view of the current state of the prior art, enables the drilling mechanism at each station to achieve stable lifting and lowering while allowing the drilling mechanism at each station to share a common set of linkage guide components, effectively reducing the overall size of the drilling machine and facilitating efficient drilling of round workpieces in confined spaces.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a five-station automatic drilling machine, including a support platform, a power distribution box on one side of the support platform, a support plate installed at the top center of the support platform, and five drilling stations arranged in a ring on the support platform outside the support plate. Each drilling station is equipped with a linkage guide assembly, which includes a linkage frame, a connecting rod, and a guide rod. The linkage frame is located on the upper side of each drilling station and the power distribution box, the connecting rod is located at the bottom end of the linkage frame directly opposite each drilling station, and the guide rod is connected to the bottom end of the connecting rod. A drilling mechanism is installed on the support platform below the guide rod. The drilling mechanism includes a drilling motor, a connecting frame, a drill bit, and an electric cylinder. The fixed part of the electric cylinder is connected to the support platform, the top of the telescopic part of the electric cylinder has a hollow structure, and the telescopic part of the electric cylinder slides with the guide rod.

[0008] Furthermore, a laser sensor is also installed in a ring shape on the support platform outside the support plate, and a PLC controller is installed on the support platform on one side of the distribution box.

[0009] By adopting the above technical solution, the laser sensor consists of a laser emitter and a receiver. When the circular workpiece is placed on the support plate, the optical path between the emitter and the receiver on the laser sensor is blocked. At this time, the laser emitter can easily feed back information to the PLC controller, thereby enabling the drilling motors in each drilling mechanism to start synchronously under the action of the PLC controller, thus realizing synchronous drilling of the circular workpiece at multiple workstations.

[0010] Furthermore, the PLC controller is electrically connected to both the laser sensor and the drilling motor.

[0011] By adopting the above technical solution, the PLC controller mainly controls the orderly start and stop of each of the punching motors by sending instructions.

[0012] Furthermore, a baffle is installed on the upper periphery of the support platform, a chip removal groove is installed on the upper side of the back of the support platform, and a waste bin is provided on the back of the support platform below the chip removal groove.

[0013] By adopting the above technical solution, the baffle is mainly used to block the splashing of drilling debris in all directions. The chip discharge groove can ensure that the drilling debris on the upper side of the support platform can be smoothly discharged into the waste bin for centralized collection.

[0014] Furthermore, the support platform is arranged in a downward sloping manner along the width direction toward the chip removal groove.

[0015] By adopting the above technical solution and designing the support platform as an inclined structure, it is possible to ensure convenient cleaning of drilling debris to the chip discharge groove.

[0016] Furthermore, one end of the linkage frame is bolted to the distribution box, the linkage frame is bolted to the connecting rod, the connecting rod has a bent structure, and the guide rod is bolted to the connecting rod.

[0017] By adopting the above technical solution, the guide rods on the linkage frame can slide in cooperation with the corresponding electric cylinder telescopic parts to achieve stable lifting and lowering of each drilling mechanism. At the same time, by hiding the guide rods inside the electric cylinder telescopic parts, the space for the user standing on the guide rods can be further reduced.

[0018] Furthermore, the connecting frame is connected to the telescopic part of the electric cylinder, the drilling motor is mounted on the connecting frame, and the drill bit is mounted on the power output end of the drilling motor.

[0019] By adopting the above technical solution, the drilling motor is mainly used to provide power for the rotation of the drill bit, so as to realize synchronous drilling at each station on the circular workpiece while the rotating drill bit moves downward.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the issue that existing multi-station drilling machines mainly consist of a processing table, drilling mechanisms installed at each station on the processing table, guide components installed at each drilling mechanism, and an electrical control box installed on the drilling mechanism, this type of drilling machine first places a circular workpiece on the processing table, and then activates the drilling mechanisms at each station to perform drilling on the circular workpiece. While existing multi-station drilling machines can perform drilling on circular workpieces, each drilling mechanism at each station is equipped with a separate guide component. The excessive number of guide components makes the overall size of the drilling machine large, which is inconvenient for drilling circular workpieces in confined spaces. To address the issue of efficient drilling, this invention utilizes a linkage guide mechanism, consisting of a linkage frame, connecting rods, and guide rods, installed on the upper side of the drilling mechanisms at each workstation on the support platform. This mechanism guides the drilling mechanisms at each workstation via the guide rods on the linkage frame, ensuring stable lifting and lowering of each mechanism. Because all drilling mechanisms share a common linkage guide assembly, this method avoids the cumbersome operation of separately installing guide assemblies at each workstation, as required by traditional transmission drilling methods. This significantly reduces the overall size of the drilling machine, facilitating efficient drilling of circular workpieces even in confined spaces. Attached Figure Description

[0029] like Figures 1-3 As shown, a five-station automatic drilling machine in this embodiment includes a support platform 3, a power distribution box 6 on one side of the support platform 3, a support plate 4 installed at the top center of the support platform 3, and five drilling stations arranged in a ring around the support plate 4 on the support platform 3.

The linkage frame 101 is located on the upper side of each drilling station and the power distribution box 6, the connecting rod 102 is located at the bottom of the linkage frame 101 directly opposite each drilling station, and the guide rod 103 is connected to the bottom of the connecting rod 102. A drilling mechanism 2 is installed on the support platform 3 below the guide rod 103. The drilling mechanism 2 includes a drilling motor 201 and a connecting frame. 202, drill bit 203, and electric cylinder 204, wherein the fixed part of electric cylinder 204 is connected to support platform 3, the top of the telescopic part of electric cylinder 204 is hollow, and the telescopic part of electric cylinder 204 is slidably engaged with guide rod 103. With the sliding engagement between each guide rod 103 on the linkage frame 101 and the corresponding telescopic part of electric cylinder 204, the stable lifting and lowering of each drilling mechanism 2 can be realized. At the same time, the guide rod 103 is hidden inside the telescopic part of electric cylinder 204, which can further reduce the space for the user to stand on the external part of guide rod 103. The drilling motor 201 is mainly used to provide power for the rotation of drill bit 203 so that the synchronous drilling processing at each station on the circular workpiece can be realized while the rotating drill bit 203 moves down.

[0030] like Figures 1-3 As shown, in this embodiment, a laser sensor 8 is also installed in a ring on the support platform 3 outside the support disk 4. A PLC controller 5 is installed on the support platform 3 on one side of the power distribution box 6. The laser sensor 8 consists of a laser emitter and a receiver. When the circular workpiece is placed on the support disk 4, the optical path between the emitter and the receiver on the laser sensor 8 is blocked. At this time, the laser emitter can easily feed back information to the PLC controller 5. Under the action of the PLC controller 5, the drilling motors 201 in each drilling mechanism 2 are started synchronously, thereby realizing synchronous drilling of the circular workpiece at multiple workstations. The PLC controller 5 is electrically connected to the laser sensor 8 and the drilling motors 201. The PLC controller 5 mainly controls the orderly start and stop of each drilling motor 201 by sending commands.

[0031] like Figures 1-3As shown in this embodiment, a baffle 7 is also installed on the upper periphery of the support platform 3, a chip discharge groove 9 is installed on the upper side of the back of the support platform 3, and a waste bin 10 is provided on the back of the support platform 3 below the chip discharge groove 9. The baffle 7 is mainly used to block the chips from splashing everywhere during drilling, and the chip discharge groove 9 can ensure that the drilling chips on the upper side of the support platform 3 can be smoothly discharged into the waste bin 10 for centralized collection.

[0032] like Figures 1-3 As shown, in this embodiment, the support platform 3 is arranged in a downward inclined manner along the width direction towards the chip removal groove 9. Designing the support platform 3 as an inclined structure can ensure convenient cleaning of drilling waste chips to the chip removal groove 9. One end of the linkage frame 101 is bolted to the distribution box 6. The linkage frame 101 is bolted to the connecting rod 102. The connecting rod 102 has a bent structure. The guide rod 103 is bolted to the connecting rod 102. The connecting frame 202 is connected to the telescopic part of the electric cylinder 204. The drilling motor 201 is installed on the connecting frame 202. The drill bit 203 is installed on the power output end of the drilling motor 201.

[0033] The specific implementation process of this embodiment is as follows: During processing, the circular workpiece to be drilled is first placed on the support platform 3 and fixed. Then, the equipment is connected to an external power source. Then, the rotating drill bit 203 is driven to move down under the action of the electric cylinder 204, so that the circular workpiece can be drilled simultaneously at five stations. When drilling the circular workpiece at multiple stations, since the drilling mechanism 2 at each station shares a set of linkage guide components 1, the cumbersome operation of having to set up guide components at each station is avoided. This greatly reduces the overall size of the drilling machine, making it easier for the drilling machine to efficiently drill circular workpieces in confined spaces.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
