Description

Technical Field

[0001] This invention relates to the field of drilling and tapping machine technology, specifically to a three-station integrated drilling and tapping machine. Background Technology

[0002] A three-station drilling and tapping machine is an automated processing equipment that integrates drilling and tapping functions. It has three stations and can perform different processes simultaneously, improving production efficiency. Usually, different drill bits are set on the drilling machines in the three stations, which can sequentially drill, enlarge, or tap the workpiece. Different drill bits can be changed to meet the processing needs of different workpieces.

[0003] Existing three-station drilling machines mostly place the workpiece on the drilling platform below the drilling rig, and the drilling rig moves vertically up and down above the drilling platform. The drilling rigs on the drilling platform can slide laterally. By driving the sliding of the drilling rigs, the three drilling rigs are aligned with the workpieces in turn for processing. Alternatively, a large number of workpieces can be arranged on the drilling platform, and multiple workpieces can be processed in turn by the lateral sliding of the drilling rigs. However, since the drilling rigs can only slide laterally, when there are multiple positions on a workpiece that need to be processed, the workpieces need to be repeatedly adjusted for processing, which is quite cumbersome. Summary of the Invention

[0004] This invention proposes a three-station drilling and tapping integrated machine, which solves the problem that existing three-station drilling and tapping integrated machines cannot process multiple positions on a workpiece at one time.

[0005] The technical solution of the present invention is as follows: A three-station drilling and tapping integrated machine includes a base on which multiple drilling machines are mounted, and also includes a feeding platform, a material fixing frame, a feeding mechanism, and a clamping displacement mechanism. The feeding platform is disposed on the base and below the drilling machines, and a feeding channel is provided on the feeding platform. Multiple material fixing frames are provided and slidably disposed on the feeding platform. The material fixing frames are used to clamp and fix the raw materials. The feeding mechanism is disposed in the base and in the feeding channel, and is used to drive the multiple material fixing frames to move. The clamping displacement mechanism is fixedly disposed on the base and contacts the feeding platform. The clamping displacement mechanism is disposed below the drilling machines and is used to clamp and fix the material fixing frames and align the materials with the drilling machines.

[0006] The clamping displacement mechanism is configured as two, which are arranged opposite each other and are respectively located on both sides of the loading platform.

[0007] The material fixing frame is provided with two extrusion rods, which are respectively located on adjacent sides of the material fixing frame. A spring is provided between the extrusion rods and the material fixing frame. The two extrusion rods extrude the material, so that the material is located on the upper edge of the material fixing frame away from the extrusion rods.

[0008] The clamping displacement mechanism includes a first drive cylinder, a transverse displacement frame, a second drive cylinder, a cross-pushing assembly, and a fixed extrusion bar. The first drive cylinder is fixedly mounted on the base, the transverse displacement frame is slidably mounted on the base, the output end of the first drive cylinder is fixedly connected to the transverse displacement frame, the second drive cylinder is fixedly mounted on the transverse displacement frame, the cross-pushing assembly is mounted on the transverse displacement frame, the output end of the second drive cylinder is rotatably connected to the cross-pushing assembly, the fixed extrusion bar is connected to the cross-pushing assembly away from the transverse displacement frame, and the fixed extrusion bar is detachably connected to the material fixing frame. The output end of the second drive cylinder extends to push the cross-pushing assembly, and the cross-pushing assembly pushes the fixed extrusion bar away from the transverse displacement frame.

[0009] The fixed extrusion strip has multiple through holes, and multiple positioning corner blocks are detachably connected to the fixed extrusion strip. The positioning corner blocks are detachably connected to the through holes and are in contact with the material fixing frame.

[0010] Two feeding channels are provided, and the material fixing frame is positioned above the two feeding channels. The feeding mechanism includes a drive cylinder, a conveying frame, a conveying assembly, and a motor. Multiple drive cylinders are provided and fixedly mounted on the base. The output ends of the multiple drive cylinders are fixedly connected to the conveying frame, which passes through the feeding channels. Two conveying assemblies are provided, each positioned in one of the two feeding channels. The motor is fixedly mounted on the conveying frame, and both conveying assemblies are drively connected to the output ends of the motor. The system includes tensioning wheels, drive wheels, and support plates. Multiple tensioning wheels are rotatably mounted on the conveyor frame. The drive wheels are rotatably mounted on the conveyor frame and are fixedly connected to the output end of the motor. A conveyor belt is tensioned and fitted onto the tensioning wheels and drive wheels. The support plate is fixedly mounted on the conveyor frame near the drilling rig. The conveyor belt is located on the support plate near the drilling rig and is in contact with the support plate. When the output end of the drive cylinder extends, the conveyor belt and the support plate lift the material fixing frame upwards on the loading platform.

[0011] A drain outlet is provided on the side of the feeding channel. A guide plate is rotatably provided on the side of the drain outlet away from the feeding platform. When the conveying frame moves upward in the feeding channel, the conveying frame squeezes the guide plate to rotate and fit against the drain outlet.

[0012] The working principle and beneficial effects of this invention are as follows:

[0013] 1. In this invention, by setting a transverse displacement frame and a fixed extrusion strip, the first drive cylinder can drive the transverse displacement frame to slide laterally with the material, and the two second drive cylinders can adjust the longitudinal sliding of the material, which can be aligned at multiple positions, and thus multiple parts of a material can be processed at one time. Furthermore, the first drive cylinder and the second drive cylinder are set in parallel, which saves space.

[0014] 2. In this invention, by setting a material fixing frame, it is possible to fix a variety of materials and make it easy to clamp and fix them. By setting a clamping displacement mechanism, multiple materials can be moved to facilitate positioning in multiple positions, while not affecting the loading and unloading of materials.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 7 As shown, this embodiment proposes a three-station drilling and tapping integrated machine, including a base 1, on which multiple drilling machines 2 are mounted, and also including a feeding platform 3, material fixing frames 5, a feeding mechanism, and a clamping displacement mechanism. The feeding platform 3 is disposed on the base 1 and below the drilling machines 2. A feeding channel 4 is provided on the feeding platform 3. Multiple material fixing frames 5 are provided and slidably disposed on the feeding platform 3. The material fixing frames 5 are used to clamp and fix the raw materials. The feeding mechanism is disposed in the base 1 and is located in the feeding channel. In channel 4, the feeding mechanism is used to drive multiple material fixing frames 5 to move. The clamping displacement mechanism is fixedly installed on the base 1 and is in contact with the feeding platform 3. The clamping displacement mechanism is located below the drill 2. The clamping displacement mechanism is used to clamp and fix the material fixing frames 5 and align the materials with the drill 2. Multiple materials are fixed through the material fixing frames 5, and the feeding mechanism drives the material fixing frames 5 to move. The unified material fixing frames 5 make it easy to clamp multiple materials at the same time and align them with the drill 2.

[0026] like Figures 1 to 5 As shown, there are two clamping displacement mechanisms, which are arranged opposite each other. The two clamping displacement mechanisms are respectively set on both sides of the loading platform 3. During processing, the two clamping displacement mechanisms simultaneously clamp and fix the material fixing frame 5 and push it to move laterally and longitudinally, and process multiple points in sequence.

[0027] like Figures 1 to 3As shown, the material fixing frame 5 is provided with two extrusion rods 6, which are respectively located on adjacent sides of the material fixing frame 5. A spring is provided between the extrusion rods 6 and the material fixing frame 5. The two extrusion rods 6 extrude the material, so that the material is located at the corner of the material fixing frame 5 away from the extrusion rods 6. The material fixing frame 5 is provided with an opening for fixing the material. When fixing the material, the extrusion rods 6 are pulled to compress the spring. After the material is placed, the extrusion rods 6 are released to extrude and fix the material. The material is extruded into the corner of the material fixing frame 5, which also facilitates the positioning of the material.

[0028] like Figures 1 to 5 As shown, the clamping displacement mechanism includes a drive cylinder 7, a transverse displacement frame 8, a drive cylinder 9, a cross-push assembly 10, and a fixed extrusion bar 11. Drive cylinder 7 is fixedly mounted on the base 1. The transverse displacement frame 8 is slidably mounted on the base 1. The output end of drive cylinder 7 is fixedly connected to the transverse displacement frame 8. Drive cylinder 9 is fixedly mounted on the transverse displacement frame 8. The cross-push assembly 10 is mounted on the transverse displacement frame 8. The output end of drive cylinder 9 is rotatably connected to the cross-push assembly 10. The fixed extrusion bar 11 is connected to the cross-push assembly 10 away from the transverse displacement frame 8. The fixed extrusion bar 11 is detachably connected to the material fixing frame 5. The output end of drive cylinder 9 extends to push the cross-push assembly 10, and the cross-push assembly 10 pushes the fixed extrusion bar 11 away from the transverse displacement frame 8. The frame 8 and the cross-push assembly 10 are configured as two centrally cross-rotating rods. When the output end of the drive cylinder 7 pushes one of the rods, the two rods cross-rotate to push the transverse displacement frame 8 to move. After the fixed extrusion strips 11 on the two clamping displacement mechanisms clamp and fix the material fixing frame 5 on both sides, the output ends of the two drive cylinders 9 can extend and shorten respectively to push the material fixing frame 5 to slide in the direction perpendicular to the loading platform 3. At the same time, the two drive cylinders 7 simultaneously push the two transverse displacement frames 8 to slide in the direction parallel to the loading platform 3. Through the cooperation of each drive cylinder 7 and drive cylinder 9, the displacement of the material fixing frame 5 clamped and fixed by the fixed extrusion strips 11 can be realized, thereby processing multiple positions sequentially.

[0029] like Figures 4 to 5 As shown, the fixed extrusion strip 11 has multiple through holes, and multiple positioning corner blocks 12 are detachably connected to the fixed extrusion strip 11. The positioning corner blocks 12 are detachably connected to the through holes and are in contact with the material fixing frame 5. Since the size of the material is diverse, the size of the material fixing frame 5 can also be set in various ways. When the size of the material fixing frame 5 is changed, the clamping of the material fixing frame 5 can be adjusted by changing the position of the positioning corner blocks 12 on the fixed extrusion strip 11. During processing, the material fixing frame 5 needs to be placed on the loading platform 3 for loading and unloading through external loading and unloading devices.

[0030] like Figures 6 to 7 As shown, there are two feeding channels 4, and the material fixing frame 5 is set above the two feeding channels 4. The feeding mechanism includes a drive cylinder 13, a conveying frame 14, a conveying assembly, and a motor 15. Multiple drive cylinders 13 are provided and are fixedly installed on the base 1. The output ends of the multiple drive cylinders 13 are fixedly connected to the conveying frame 14. The conveying frame 14 passes through the feeding channel 4. There are two conveying assemblies, which are respectively set in the two feeding channels 4. The motor 15 is fixedly installed on the conveying frame 14, and both conveying assemblies are driven by the output ends of the motor 15. The conveying assembly includes a tension wheel 16, a drive wheel 17, and a support plate 18. Multiple tension wheels 16 are provided and are rotatably mounted on the conveying frame 14. The drive wheel 17 is rotatably mounted on the conveying frame 14 and is connected to the motor 18. The output end of the motor 15 is fixedly connected. The tensioning wheel 16 and the drive wheel 17 are fitted with a conveyor belt. The support plate 18 is fixedly installed on the side of the conveyor frame 14 near the drill 2. The conveyor belt is located on the side of the support plate 18 near the drill 2 and is in contact with the support plate 18. When the output end of the drive cylinder 13 extends, the conveyor belt and the support plate 18 lift the material fixing frame 5 on the loading platform 3. When the output end of the drive cylinder 13 pushes the conveyor frame 14 upward, the support plate 18 supports the conveyor belt. The conveyor belt is in contact with the material fixing frame 5. The output end of the motor 15 drives the conveyor belt to move through the drive wheel 17 and drives the material fixing frame 5 to move. In this embodiment, there are three tensioning wheels 16. The three tensioning wheels 16 tighten the conveyor belt, so that the drive wheel 17 has a large angle to contact the conveyor belt.

[0031] like Figure 7 As shown, a drain port 19 is provided on the side of the feeding channel 4. A guide plate 20 is rotatably installed on the side of the drain port 19 away from the feeding platform 3. When the conveyor frame 14 moves upward in the feeding channel 4, the conveyor frame 14 squeezes the guide plate 20 to rotate and fit against the drain port 19. When the conveyor belt conveys the material fixing frame 5, it will squeeze and rotate the guide plate 20 to close. When processing, the conveyor frame 14 moves downward, and the guide plate 20 will automatically rotate and open by its own weight or by setting a spring, so that the cooling oil and debris during processing flow into the drain port 19 through the feeding channel 4. This facilitates recycling and reduces the impact of the cooling oil on the motor 15 and the conveyor belt.

[0032] In this embodiment, the output end of the drive cylinder 13 pushes the conveyor frame 14 upward, the support plate 18 and the conveyor belt move upward, the output end of the motor 15 drives the conveyor belt to move through the drive wheel 17, the conveyor belt drives the material fixing frame 5 to move, after the material fixing frame 5 is driven below the drill 2, the output end of the drive cylinder 13 shortens, so that the conveyor belt separates from the material fixing frame 5, the guide plate 20 rotates and tilts after separating from the conveyor frame 14, the output end of the drive cylinder 9 extends and pushes the fixed extrusion strip 11 to clamp the material fixing frame 5 through the cross push assembly 10, the output end of the drive cylinder 7 can drive the transverse displacement frame 8 to slide, thereby driving the cross push assembly 10 and the fixed extrusion strip 11 to drive the material fixing frame 5 to slide on the loading platform 3, thereby processing multiple positions. After the material completes the processing steps below the corresponding drill 2, it can be moved to the next step of the drill 2 for the next step of processing.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
