Description
Technical Field
[0001] This utility model relates to the field of CNC drilling and tapping technology, specifically to a CNC drilling and tapping feeding device. Background Technology
[0002] CNC drilling and tapping refers to the process of automatically completing drilling and tapping operations using computer numerical control (CNC) technology and CNC machine tools. High-precision and high-efficiency processing is achieved through program control. During drilling, a feeding device is used to transfer the workpiece to be drilled to the bottom of the drill for processing.
[0003] In existing feeding devices, the workpiece to be processed is placed on an inclined frame. The workpiece slides down the inclined frame in an inclined direction, moving it to the side of the fixture. Then, a cylinder on the side drives a piston rod to move a pusher block, which pushes the workpiece to the bottom of the drill, thus achieving the transfer of the workpiece to be processed. However, if the workpieces to be processed on the inclined frame are not arranged tightly, the workpieces cannot move smoothly to one end of the fixture due to the compression of the workpieces and the inclination of the inclined frame. Therefore, an auxiliary limiting feeding device is needed to ensure that the workpieces to be processed on the inclined frame can move smoothly to one side of the fixture. Utility Model Content
[0004] The purpose of this utility model is to provide a CNC drilling and tapping feeding device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a CNC drilling and tapping feeding device, comprising: A feeding assembly, the feeding assembly including an inclined frame; the inclined frame is fixed to one edge of the top of the machine body; The limiting assembly includes a vertical plate, a spring, a pressing plate, and a locking block; the vertical plate is locked to the inner side of the outer end of the inclined frame, the spring is fixed to the lower side of one side of the vertical plate, the pressing plate is fixed to the other end of the spring, and the locking block is fixed to the top of the pressing plate.
[0005] Furthermore, slots are provided on both sides inside the inclined frame, with one end of the slot being open and a slider slidably connected inside the slot.
[0006] Furthermore, the opposite ends of the slider are fixedly connected to both sides of the extrusion plate, and plug-in blocks are fixedly connected to both sides of the bottom end of the vertical plate.
[0007] Furthermore, a set of mounting grooves is provided at the bottom inner side of the outer side of the inclined frame, and the inner side of the mounting groove is inserted into the plug-in block, and the two are attracted to each other.
[0008] Furthermore, the feeding assembly also includes a connecting rail, a cylinder, a piston rod, and a push block; the connecting rail is fixed to the other edge of the top of the machine body, the cylinder is fixed to the outer end of the connecting rail, the piston rod is slidably connected to the inside of one end of the cylinder, and the push block is fixed to one end of the piston rod and slidably connected to the surface of one end of the connecting rail.
[0009] Furthermore, it also includes anti-misalignment components; The anti-misalignment component includes a fixed frame, a stop block, and a limiting rod; the fixed frame is snapped into the middle section of the push block and its bottom end is fixedly connected to the connecting rail, the stop block is fixed to the center of the top of the push block, and the limiting rod passes through the snap-fit point between the fixed frame and the upper end of the push block.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0017] Please see Figures 1-4 As shown, this utility model is a CNC drilling and tapping feeding device, comprising: The feeding assembly includes an inclined frame 11; the inclined frame 11 is fixed to one edge of the top of the machine body. The feeding assembly also includes a connecting rail 12, a cylinder 13, a piston rod 14, and a push block 15; the connecting rail 12 is fixed to the other edge of the top of the machine body, the cylinder 13 is fixed to the outer end of the connecting rail 12, the piston rod 14 is slidably connected to the inside of one end of the cylinder 13, and the push block 15 is fixed to one end of the piston rod 14 and slidably connected to the surface of one end of the connecting rail 12. The inclined frame 11 is used to place the workpiece to be processed. The connecting rail 12 is used to connect the cylinder 13 and move the push block 15. The cylinder 13 is used to drive the piston rod 14 to push the push block 15. The piston rod 14 is used to push the push block 15. The push block 15 is used to push the workpiece to be processed to the side of the fixture.
[0018] The limiting assembly includes a vertical plate 21, a spring 22, a pressing plate 23, and a snap-fit block 26; the vertical plate 21 is snapped into the inner side of the outer end of the inclined frame 11, the spring 22 is fixed to the lower side of one side of the vertical plate 21, the pressing plate 23 is fixed to the other end of the spring 22, and the snap-fit block 26 is fixed to the top of the pressing plate 23. The vertical plate 21 is used to connect the spring 22, the spring 22 is used to connect and move the pressing plate 23, the pressing plate 23 is used to press and limit the workpieces to be processed arranged inside the inclined frame 11, and the snap-fit block 26 is used to snap and limit the workpieces to be processed behind, so as to better push the workpieces to be processed behind to fill the gap in front.
[0019] The inclined frame 11 has slots 24 on both sides inside, one end of which is open, and a slider 25 is slidably connected inside the slot 24. The opposite ends of the slider 25 are fixedly connected to both sides of the extrusion plate 23, and the bottom ends of the vertical plate 21 are fixedly connected to the two sides of the plug-in block 28. A set of mounting grooves 27 is provided at the bottom inner side of the outer side of the inclined frame 11. The inner side of the mounting grooves 27 is inserted into the plug block 28, and the two are attracted to each other. The slot 24 is used for the connection and movement of the slider 25. The slider 25 is used for the connection between the extrusion plate 23 and the slot 24. The plug block 28 and the mounting groove 27 are used for the connection between the bottom end of the vertical plate 21 and the inner side of the inclined frame 11. The surface of the plug block 28 has magnetic force and can be attracted to the inner side of the mounting groove 27. The plug block 28 is inserted into the mounting groove 27, and the two are attracted by magnetic force, so that the vertical plate 21 and the inclined frame 11 are connected together, which facilitates the loading and unloading of the components.
[0020] Working principle: When the component is not in use, the workpiece to be processed is not placed inside the inclined frame 11. When the component is in use, the workpiece to be processed is placed inside the inclined frame 11, and the locking block 26 is manually locked to the workpiece behind it. This causes the pressing plate 23 and the locking block 26 to be pressed and limited by the spring 22. When the workpiece to be processed at the inner end of the inclined frame 11 slides down the inclined direction of the inclined frame 11 to the side of the fixture, the force of the pressing spring 22 weakens, and the spring 22 gradually unfolds. The unfolding force of the spring 22 pushes the slider 25 to move in the slot 24, causing the pressing plate 23 to move through the slider 25. This causes the pressing plate 23 and the locking block 26 to push the workpiece behind it forward through the spring 22. This causes the workpiece behind it to be filled in by the pressing plate 23 and the spring 22 within the inclined frame 11, thereby preventing the workpiece from not moving smoothly to one end of the fixture if the workpieces on the inclined frame 11 are not tightly arranged.
[0021] Please see Figures 1-2 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes: Misplaced component; The anti-misalignment component includes a fixed frame 31, a stop block 32, and a limiting rod 35; the fixed frame 31 is snapped into the middle section of the push block 15 and its bottom end is fixedly connected to the connecting rail 12; the stop block 32 is fixed to the center of the top of the push block 15; and the limiting rod 35 passes through the snap-fit point between the fixed frame 31 and the upper end of the push block 15. The fixing bracket 31 is used for the insertion of the limiting rod 35, and the abutment 32 is used to abut against the fixing bracket 31 to make the limiting groove 34 and the limiting hole 33 aligned. The limiting rod 35 limits the push block 15 when not in use to prevent the push block 15 from moving due to the unexpected situation of the cylinder 13.
[0022] The fixed frame 31 has a limiting hole 33 at the point where it passes through the limiting rod 35, and the push block 15 has a limiting groove 34 at the point where it passes through the limiting rod 35; the limiting hole 33 and the limiting groove 34 are threadedly connected to the limiting rod 35, and an annular block 36 is fixedly connected to the upper surface of the limiting rod 35. The limiting hole 33 and the limiting groove 34 are used together for the insertion and rotation of the limiting rod 35, thereby limiting the push block 15 when it is not in use. The annular block 36 is used to better limit the push block 15 with the limiting rod 35. When the cylinder 13 drives the piston rod 14 to move backward, the piston rod 14 drives the push block 15 to move towards the cylinder 13, causing the push block 15 to drive the abutment 32 to abut against the fixed frame 31, causing the limiting groove 34 to align with the limiting hole 33, and the limiting rod 35 to be rotated and inserted into the limiting hole 33 and the limiting groove 34, so that the limiting rod 35 limits the push block 15 after use.
[0023] Working principle: When the component is not in use, the limiting rod 35 is inserted into the limiting hole 33, and the push block 15 is in normal use. After the push block 15 is used, the cylinder 13 drives the piston rod 14 to move backward. The piston rod 14 drives the push block 15 to move towards the cylinder 13, causing the push block 15 to drive the abutment 32 to abut against the fixed frame 31. At this time, the cylinder 13 stops driving, causing the limiting groove 34 to align with the limiting hole 33. The limiting rod 35 is manually rotated and inserted into the limiting hole 33 and the limiting groove 34, so that the limiting rod 35 is connected to the limiting groove 34 and the limiting hole 33 through threads, so that the limiting rod 35 limits the push block 15 after use, thereby preventing the push block 15 from moving due to the unexpected situation of the cylinder 13.
