Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a CNC machine tool for dual-axis machining. Background Technology

[0002] A tapping machine is a mechanical processing device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges with different specifications of through holes or blind holes.

[0003] For example, Chinese patent CN220717992U, concerning a tapping machine, relates to the technical field of machining equipment. It includes a base, a column, a mounting box mounted on the column, and a worktable mounted on the column. The mounting box is located above the worktable. A tapping head is rotatably mounted on the side of the mounting box facing the worktable, and the tapping head is vertically detachable from the mounting box. A tapping hole is formed on the worktable. A waste chip collection box is located on the side of the worktable away from the mounting box. A waste chip collection groove is formed on the side of the waste chip collection box facing the worktable, and the waste chip collection groove is opposite to the tapping hole. A locking mechanism is provided between the worktable and the waste chip collection box. This application installs a waste chip collection box on the side of the worktable away from the mounting box. Waste chips generated during the tapping process fall through the tapping hole into the waste chip collection groove, where the waste chip collection box collects the waste chips, preventing them from falling onto the floor of the tapping workshop and resulting in a cleaner environment.

[0004] However, the above structure cannot perform automated tapping, resulting in low tapping efficiency and making it unsuitable for practical use.

[0020] Beneficial effects

[0021] This invention uses an external vibrating disc to transport the workpiece into the guide channel. The direct vibration then transports the workpiece from the guide channel to the feeding assembly. The feeding assembly pushes the workpiece to the front of the pushing assembly, which in turn pushes the workpiece from the feeding assembly into the support assembly. The dual-axis tapping device moves downwards, causing the positioning and detection assembly to move downwards as well. Workpieces adjacent to the workpiece being processed by the dual-axis tapping device are then inserted into the positioning and detection assembly. The positioning and detection assembly positions the adjacent workpieces, thus aligning them with the workpiece being processed by the dual-axis tapping device. The dual-axis tapping device then performs the tapping process, achieving automatic and standardized tapping. Simultaneously, as the positioning and detection assembly moves downwards, it can detect any broken taps within the processed workpiece, facilitating timely detection of tap breakage. Furthermore, the up-and-down movement of the positioning and detection assembly can cause the waste material guide assembly to swing, facilitating the automatic discharge of debris from the waste material guide assembly.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1

[0033] Please refer to the instruction manual appendix. Figure 1-5 A dual-axis CNC machine tool, including a support table 1;

[0034] The top of the support platform 1 is connected to the support frame 2;

[0035] The top of the support frame 2 is connected to a support component 5 for supporting the workpiece assembly;

[0036] A dual-axis tapping device 3 for dual-hole tapping is provided above the support assembly 5. The output end of the dual-axis tapping device 3 is connected to a positioning detection component 7 for positioning and broken tap detection. The workpiece adjacent to the workpiece processed by the dual-axis tapping device 3 is inserted into the positioning detection component 7. A waste material guiding component 6 for waste material guiding is rotatably installed inside the support assembly 5. The positioning detection component 7 is movably connected to the waste material guiding component 6. The positioning detection component 7 is inserted into the straight hole of the workpiece earlier than the dual-axis tapping device 3.

[0037] The rear end of the support component 5 is provided with a feeding component 8 for feeding materials. The rear end of the feeding component 8 is connected to a pushing component 4 for pushing materials. The pushing component 4 is installed on the top of the support platform 1. The feeding component 8 is provided with a vertical vibrator 10 at one end of the pushing component 4. The vertical vibrator 10 is fixedly installed on the top of the support platform 1. The top of the vertical vibrator 10 is connected to a guide channel 9.

[0038] The material guide channel 9 is in close contact with the output end of the external vibrating plate.

[0039] An external vibrating plate transports the workpiece to the guide channel 9. The direct vibration 10 transports the workpiece in the guide channel 9 to the feeding component 8. The feeding component 8 pushes the workpiece to the front of the pushing component 4. The pushing component 4 pushes the workpiece in the feeding component 8 to the support component 5. The dual-axis tapping device 3 moves downward. The dual-axis tapping device 3 drives the positioning detection component 7 downward. The workpiece adjacent to the workpiece processed by the dual-axis tapping device 3 is inserted into the positioning detection component 7. The positioning detection component 7 positions the workpiece adjacent to the workpiece processed by the dual-axis tapping device 3, thereby positioning it with the workpiece processed by the dual-axis tapping device 3. Then, the dual-axis tapping device 3 performs tapping processing to achieve automatic and standardized tapping. At the same time, when the positioning detection component 7 moves downward, it can detect whether there is a broken tap in the processed workpiece, which is conducive to timely detection of tap breakage. In addition, when the positioning detection component 7 moves up and down, it can drive the waste guide component 6 to swing, which facilitates the automatic discharge of debris on the waste guide component 6.

[0040] Support assembly 5 includes side support plate 51 and Z-shaped pressure plate 52. The waste material guiding assembly 6 is provided with side support plate 51 on both sides. The side support plate 51 is fixedly installed on the top of the support frame 2. The Z-shaped pressure plate 52 is fixedly connected to the top of the side support plate 51. The bottom of the workpiece is in contact with the top of the side support plate 51, the side wall of the workpiece is in contact with the inner wall of the Z-shaped pressure plate 52, and the top of the workpiece is in contact with the inner top of the Z-shaped pressure plate 52.

[0041] The pushing component 4 pushes the workpiece to the top of the side support plate 51 of the supporting component 5, and the side support plate 51 and the Z-shaped pressure plate 52 cooperate to vertically limit the workpiece;

[0042] The waste material guiding assembly 6 includes a guide plate 61 and a horizontal shaft 62. The left and right ends of the horizontal shaft 62 are rotatably connected to the inner wall of the side support plate 51. The guide plate 61 is fixedly connected to the horizontal shaft 62. The position where the horizontal shaft 62 is connected to the guide plate 61 is located behind the center of the guide plate 61, and the horizontal shaft 62 is located behind the tapping part of the dual-axis tapping device 3.

[0043] The chips processed by the dual-axis tapping machine 3 fall onto the guide plate 61. The positioning detection component 7 moves downward and contacts the rear end of the guide plate 61. The rear end of the guide plate 61 rotates downward along the horizontal axis 62, and the front end of the guide plate 61 rotates upward along the horizontal axis 62. The positioning detection component 7 separates from the rear end of the guide plate 61. Since the connection between the horizontal axis 62 and the guide plate 61 is located behind the center of the guide plate 61, the front end of the guide plate 61 is lower than the top of the support frame 2 under the weight, and the rear end of the guide plate 61 is higher than the front end of the guide plate 61. The front end of the guide plate 61 rotates downward along the horizontal axis 62. The positioning detection component 7 moves up and down to make the guide plate 61 swing back and forth along the horizontal axis 62, which facilitates the shaking and unloading of chips on the guide plate 61, and helps to discharge chips, avoiding chip accumulation between the side support plates 51 and preventing chips from affecting the subsequent processing of the dual-axis tapping machine 3.

[0044] The positioning detection component 7 includes a connecting frame 71, a positioning rod 72, a guide rod 73, and a guide cone 74. The output end of the dual-axis tapping device 3 is rotatably connected to the connecting frame 71 through a bearing. The connecting frame 71 is slidably connected to the guide rod 73 through a sliding hole. The top of the guide rod 73 is fixedly connected to the housing of the dual-axis tapping device 3. Pressure sensors 75 are symmetrically fixedly connected to the front end of the connecting frame 71. The output end of the pressure sensor 75 and the left and right ends of the rear end of the connecting frame 71 are both positioned by the positioning rod 72. The bottom of the positioning rod 72 is fixedly connected to the guide cone 74.

[0045] The output end of the dual-axis tapping machine 3 rotates and moves simultaneously. The output end of the dual-axis tapping machine 3 drives the connecting frame 71 downward along the guide rod 73. The connecting frame 71 drives the positioning rod 72 downward, and the positioning rod 72 drives the guide cone 74 downward. The rear guide cone 74 is inserted into the hole of the untapping workpiece, and the front guide cone 74 is inserted into the hole of the tapped workpiece. This limits the two adjacent sets of workpieces below the dual-axis tapping machine 3, thereby limiting the workpieces below the dual-axis tapping machine 3. In conjunction with the support component 5, it achieves the overall positioning of the workpieces below the dual-axis tapping machine 3, which is conducive to the accurate processing of the dual-axis tapping machine 3 and ensures the tapping quality. When there is tap residue in the hole of the workpiece below the pressure sensor 75, the pressure sensor 75 detects the pressure value when the guide cone 74 comes into contact with the residual tap, and stops tapping, which is conducive to the rapid detection of tap breakage.

[0046] The feeding assembly 8 includes a straight plate 81, a movable plate 82, a slot 83, a rear baffle 84, a second cylinder 85, a front baffle 86, and a second guide rail assembly 87. The slide rail of the second guide rail assembly 87 and the rear baffle 84 are fixedly installed on the rear side of the support frame 2. The slide rail of the second guide rail assembly 87 is located in front of the rear baffle 84. The right side of the rear baffle 84 contacts the front left side of the guide channel 9. The support frame 2 is fixedly connected to the front side of the guide rail of the second guide rail assembly 87. The left end of the front baffle 86 is in close contact with the side wall of the right side support plate 51. The bottom of the movable plate 82 is fixedly connected to the slider of the second guide rail assembly 87. The end of the movable plate 82 away from the support assembly 5 is fixedly connected to the straight plate 81. The straight plate 81 is fixedly connected to the output end of the second cylinder 85, and the second cylinder 85 is fixedly installed on the top of the support platform 1. The movable plate 82 has a slot 83 that cooperates with the guide channel 9.

[0047] The second cylinder 85 of the feeding assembly 8 extends, and the second cylinder 85 drives the straight plate 81 to move. Under the action of the second guide rail assembly 87, the straight plate 81 drives the moving plate 82 to move. The moving plate 82 drives the slot 83 to move to the guide channel 9. The vertical vibrator 10 conveys the workpiece to the slot 83 through the guide channel 9. The front baffle 86 prevents the workpiece from moving further in the slot 83. The second cylinder 85 of the feeding assembly 8 retracts, and the second cylinder 85 drives the straight plate 81 to move. Under the action of the second guide rail assembly 87, the straight plate 81 drives the moving plate 82 to move. The moving plate 82 conveys the workpiece in the slot 83 to the front of the pushing assembly 4, which facilitates the conveying of the workpiece from the guide channel 9 to the front of the pushing assembly 4.

[0048] The pushing component 4 includes a first cylinder 41, a support plate 42, a first guide rail assembly 43, a push rod 44, an insertion hole 45, and a support base 46. The support base 46 is fixedly installed on the top of the support platform 1 and is located on the rear side of the support frame 2. The first cylinder 41 is fixedly connected to the support base 46. The output end of the first cylinder 41 is fixedly connected to the support plate 42. The push rod 44 is symmetrically fixedly connected to the front side wall of the support plate 42. The rear baffle 84 has an insertion hole 45, and the push rod 44 slides in the insertion hole 45. The bottom of the support plate 42 is fixedly connected to the slider of the first guide rail assembly 43. The guide rail of the first guide rail assembly 43 is fixedly installed on the top of the support frame 2.

[0049] After the feeding assembly 8 conveys the workpiece to the front of the pushing assembly 4, the first cylinder 41 drives the support plate 42 to move. The support plate 42 drives the push rod 44 to pass through the insertion hole 45. The push rod 44 pushes the workpiece in the slot 83 to the space between the side support plate 51 and the Z-shaped pressure plate 52, so that the workpiece in the feeding assembly 8 can be pushed into the support assembly 5.
