Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a drilling and tapping machine. Background Technology

[0002] Machining, or machining, refers to the process of using mechanical equipment to cut, drill, mill, and turn raw materials to achieve the required dimensions and shapes. Machining is widely used in manufacturing to produce various parts and products. It includes not only traditional metal cutting but also the processing of various materials such as plastics and powder metallurgy.

[0003] Drilling and tapping are the most common machining processes. Currently, when drilling and tapping parts on existing machine tools, the machine spindle is changed to a drilling tool for drilling the initial hole, and then a tapping tool is changed to tap the workpiece. Using existing machine tools for complete drilling and tapping of workpieces has the following disadvantages: 1. Frequent tool changes are required during machining, affecting machining efficiency; 2. Machine downtime is required for workpiece clamping and unclamping, occupying valuable machining time.

[0004] Therefore, how to provide a drilling and tapping machine with a simpler and more reasonable structural design that can improve the efficiency of drilling and tapping, as well as the efficiency of workpiece clamping and unloading, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a drilling and tapping machine with a simpler and more reasonable structural design, which can improve the efficiency of drilling and tapping, and improve the efficiency of workpiece clamping and unloading.

[0006] To achieve the above objectives, this utility model provides a drilling and tapping machine, including a frame, a turntable rotatably mounted on the frame, a turntable rotation drive mechanism mounted on the frame to drive the turntable to rotate horizontally, four clamping mechanisms spaced apart on the turntable along the circumferential direction, each clamping mechanism having a clamping port at its outer end capable of clamping the end of a rod-shaped workpiece, an automatic feeding mechanism, a drilling mechanism, a tapping mechanism, and a material ejection mechanism are provided on the outer side of the turntable on the frame, corresponding to each clamping mechanism, respectively; the automatic feeding mechanism can push the workpieces out one by one from the discharge port and allow the distal end of the workpiece to enter the clamping port of the clamping mechanism for clamping, completing the clamping; the drilling mechanism and the tapping mechanism each have drilling tools and tapping tools, and each drills and taps the workpiece in the clamping port of the clamping mechanism; the material ejection mechanism includes a material ejection plate mounted on the frame, the material ejection plate having a material ejection groove inclined downwards and outwards, with the inner end of the material ejection groove connecting to the outer side of the clamping port of the clamping mechanism, and the distal end of the material ejection groove located outside the turntable.

[0007] In this drilling and tapping machine, the workpiece is placed in an automatic feeding mechanism, which pushes the workpieces out one by one from the discharge port, ensuring that the far end of each workpiece enters the clamping slot of the fixture mechanism for clamping. Then, the turntable rotates a preset angle (90 degrees) so that the fixture mechanism holding the workpiece is aligned with the drilling mechanism. The drilling tool on the drilling mechanism performs drilling operations on the workpiece. After drilling, the turntable rotates another preset angle (90 degrees) so that the fixture mechanism is aligned with the tapping mechanism. The tapping tool on the tapping mechanism performs tapping operations on the workpiece. After tapping, the turntable rotates another preset angle (90 degrees) so that the fixture mechanism holding the workpiece is aligned with the unloading mechanism. The workpiece in the clamping slot of the fixture mechanism exits and enters the unloading groove on the unloading plate, falling out from the outside of the unloading groove, completing the processing. This equipment offers a higher degree of automation in drilling and tapping, significantly saving manpower. Furthermore, it eliminates the need for tool changes and clamping waiting, further improving processing efficiency.

[0008] As an optimization, the clamping mechanism includes a mounting base plate mounted on a turntable, a vertically upward mounting support plate at the front end of the mounting base plate, and a clamping device mounted and fixed on the mounting support plate.

[0009] In this way, by setting up a mounting base plate and a mounting support plate, it is easier to install and fix the chuck device.

[0010] In the above technologies, the chuck device is an existing structure that can be purchased and used directly on the market, and will not be described in detail here. The drilling mechanism and tapping mechanism are also existing structures that can be purchased and used directly on the market. Both the drilling mechanism and the tapping mechanism use a cylinder-driven mechanism to move towards the workpiece, and use an electric drive to rotate the drilling tool and tapping tool at the front of the tool chuck, which will not be described in detail here. The turntable rotation drive mechanism can be a servo motor installed inside the frame, which drives the turntable to rotate through gear transmission. The turntable rotation drive mechanism is also a conventional design.

[0011] As an optimization, a vertically upward fixed support plate is provided at the rear end of the mounting base plate; and a fixed block is provided at the center of the upper surface of the turntable. A vertically upward fixed column is detachably connected to the fixed block. A horizontally outward fixed rod is provided on the outer circumference of the fixed column and corresponding to the fixed support plate. The far end of each fixed rod is connected to the fixed support plate.

[0012] In this way, by setting a fixed support plate at the rear end of the mounting base plate, and then setting a fixed block, a fixed column and a fixed rod to connect the four mounting base plates together, the whole structure becomes more stable and reliable.

[0013] Furthermore, a horizontally positioned fixing block is connected and fixed to the upper end of the fixed support plate, and a fixing head is provided on the fixing block, so that the far ends of the fixing rods are each connected and fixed on the fixing plate.

[0014] Furthermore, the lower end of the fixed block is provided with a threaded rod segment, and the threaded rod segment is threadedly connected in a threaded hole on the upper end face of the fixed block.

[0015] As an optimization, the frame includes a horizontally arranged frame plate at the top, and the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism are respectively installed at the four corners of the frame plate.

[0016] In this way, by setting up the frame plate, it is easier to arrange the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism.

[0017] As an optimization, a flat box-shaped mounting box with an open top is provided on the surface of the frame plate, and the turntable is arranged inside the mounting box; and the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism are arranged outside the outer contour of the mounting box.

[0018] In this way, by setting up a mounting box above the frame plate, the iron filings generated during machining can be collected and processed more effectively.

[0019] As an optimization, the ejection mechanism includes a support block fixed inside the mounting box, and the ejection plate is provided on the support block. The ejection groove includes a front section and a rear section, and the inclination angle of the front section is set to be smaller than that of the rear section. The inner end of the front section of the ejection groove is connected to the outer side of the clamping port of the fixture mechanism, and the outer end of the rear section of the ejection groove extends to the outside of the mounting box.

[0020] This makes the design of the unloading mechanism simpler and allows for better transport of the processed workpiece to the outside of the machine frame.

[0021] As an optimization, the automatic feeding mechanism includes a material container mounted on the frame via a mounting base. The material container has an equilateral triangular box structure with an open top, and the distance between the two inner side walls of the material container matches the length of the workpiece. A through hole is provided at the lower end of the material container, extending through its thickness direction. The position between the two through holes in the material container forms a feeding waiting station, allowing the workpieces in the material container to fall into the feeding waiting station one by one under the action of gravity. A connecting block is provided on the mounting base corresponding to the inner side of the material container. The connecting block has a connecting groove, with the inner end of the connecting groove connecting to the through hole and the far end of the connecting groove connecting to the clamping port of the fixture mechanism. A feeding cylinder is also provided on the mounting base. A feeding push rod is connected to the piston rod end of the feeding cylinder, and the feeding cylinder can drive the feeding push rod to extend through the through hole and push the workpiece horizontally and through the connecting groove into the clamping port of the fixture mechanism.

[0022] This design simplifies the automatic feeding mechanism, improves feeding efficiency, and enhances feeding reliability. It also allows workers to operate the machine without interruption.

[0023] As an optimization, a support rod is also provided on the frame, and an operation panel is installed on the support rod.

[0024] In summary, the aforementioned drilling and tapping machine, by arranging four clamping mechanisms on a turntable and correspondingly setting an automatic feeding mechanism, drilling mechanism, tapping mechanism, and unloading mechanism on the outside of the turntable, can achieve non-stop clamping and unloading when processing workpieces, thereby improving the efficiency of drilling and tapping, as well as the efficiency of workpiece clamping and unloading.

[0034] like Figures 1 to 8 As shown, a drilling and tapping machine includes a frame 1, a turntable 2 rotatably mounted on the frame, and a turntable rotation drive mechanism on the frame capable of driving the turntable to rotate horizontally. Four clamping mechanisms 3 are spaced apart on the turntable along the circumferential direction, each clamping mechanism having a clamping opening at its outer end capable of clamping the end of a rod-shaped workpiece. An automatic feeding mechanism 4, a drilling mechanism 5, a tapping mechanism 6, and a retraction mechanism 7 are provided on the outer side of the turntable on the frame, corresponding to each clamping mechanism. The automatic feeding mechanism can... Workpieces are pushed out one by one from the discharge port and the corresponding far end of the workpiece enters the clamping port of the fixture mechanism to complete the clamping; the drilling mechanism and the tapping mechanism each have a drilling tool 8 and a tapping tool 9, and each drills and taps the workpiece in the clamping port of the fixture mechanism; the unloading mechanism includes an unloading plate 10 installed on the frame, and an unloading groove 11 is provided on the unloading plate, which is inclined to the outside and downward, so that the inner end of the unloading groove is connected to the outside of the clamping port of the fixture mechanism, and the far end of the unloading groove is located outside the turntable.

[0035] In this drilling and tapping machine, the workpiece is placed in an automatic feeding mechanism, which pushes the workpieces out one by one from the discharge port, ensuring that the far end of each workpiece enters the clamping slot of the fixture mechanism for clamping. Then, the turntable rotates a preset angle (90 degrees) so that the fixture mechanism holding the workpiece is aligned with the drilling mechanism. The drilling tool on the drilling mechanism performs drilling operations on the workpiece. After drilling, the turntable rotates another preset angle (90 degrees) so that the fixture mechanism is aligned with the tapping mechanism. The tapping tool on the tapping mechanism performs tapping operations on the workpiece. After tapping, the turntable rotates another preset angle (90 degrees) so that the fixture mechanism holding the workpiece is aligned with the unloading mechanism. The workpiece in the clamping slot of the fixture mechanism exits and enters the unloading groove on the unloading plate, falling out from the outside of the unloading groove, completing the processing. This equipment offers a higher degree of automation in drilling and tapping, significantly saving manpower. Furthermore, it eliminates the need for tool changes and clamping waiting, further improving processing efficiency.

[0036] In this specific embodiment, the clamping mechanism includes a mounting base plate 12 mounted on a turntable, a vertically upward mounting support plate 13 provided at the front end of the mounting base plate, and a clamping device mounted and fixed on the mounting support plate.

[0037] In this way, by setting up a mounting base plate and a mounting support plate, it is easier to install and fix the chuck device.

[0038] In the above technologies, the chuck device is an existing structure that can be purchased and used directly on the market, and will not be described in detail here. The drilling mechanism and tapping mechanism are also existing structures that can be purchased and used directly on the market. Both the drilling mechanism and the tapping mechanism use a cylinder-driven mechanism to move towards the workpiece, and use an electric drive to rotate the drilling tool and tapping tool at the front of the tool chuck, which will not be described in detail here. The turntable rotation drive mechanism can be a servo motor installed inside the frame, which drives the turntable to rotate through gear transmission. The turntable rotation drive mechanism is also a conventional design.

[0039] In this specific embodiment, a vertically upward fixed support plate 14 is provided at the rear end of the mounting base plate; and a fixed block 15 is provided at the center of the upper surface of the turntable. A vertically upward fixed column 16 is detachably connected to the fixed block. A horizontally outward fixed rod 17 is provided on the outer circumference of the fixed column and corresponding to the fixed support plate. The far ends of the fixed rods are connected to the fixed support plate.

[0040] In this way, by setting a fixed support plate at the rear end of the mounting base plate, and then setting a fixed block, a fixed column and a fixed rod to connect the four mounting base plates together, the whole structure becomes more stable and reliable.

[0041] Furthermore, a horizontally arranged fixing block 18 is connected and fixed to the upper end of the fixed support plate. The fixing block is provided with a fixing head, and the far ends of the fixing rods are each connected and fixed to the fixing plate.

[0042] Furthermore, the lower end of the fixed block is provided with a threaded rod segment, and the threaded rod segment is threadedly connected in a threaded hole on the upper end face of the fixed block.

[0043] In this specific embodiment, the frame includes a horizontally arranged frame plate 19 at the upper end, and the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism are respectively installed at the four corner positions of the frame plate.

[0044] In this way, by setting up the frame plate, it is easier to arrange the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism.

[0045] In this specific embodiment, a flat box-shaped mounting box 20 with an open top is provided on the upper surface of the frame plate, and the turntable is arranged inside the mounting box; and the automatic feeding mechanism, drilling mechanism, tapping mechanism and unloading mechanism are arranged outside the outer contour of the mounting box.

The ejection groove includes a front section 22 and a rear section 23, and the inclination angle of the front section is set to be smaller than that of the rear section. The inner end of the front section of the ejection groove is connected to the outer side of the clamping port of the fixture mechanism, and the outer end of the rear section of the ejection groove extends to the outside of the mounting box.

[0048] This makes the design of the unloading mechanism simpler and allows for better transport of the processed workpiece to the outside of the machine frame.

[0049] In this specific embodiment, the automatic feeding mechanism includes a material container 24 mounted on the frame via a mounting base. The material container has an equilateral triangular box structure with an open top, and the distance between the two inner side walls of the material container matches the length of the workpiece. A through hole is provided at the lower end of the material container, extending through its thickness direction. The position between the two through holes in the material container forms a feeding waiting station, allowing the workpieces in the material container to fall into the feeding waiting station one by one under the action of gravity. A connecting block 25 is provided on the mounting base corresponding to the inner side of the material container. The connecting block has a connecting groove 26, with the inner end of the connecting groove connecting to the through hole and the far end of the connecting groove connecting to the clamping port of the fixture mechanism.
