Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and in particular to a drilling and tapping device. Background Art

[0002] Tapping refers to using a certain torque to screw the tap into the bottom hole to be drilled to produce internal threads. "Rigid tapping" is also called "synchronous feed tapping". It is important to choose the right lubricant in tapping; An automatic punching and tapping device described in a patent application with publication number CN113927305A relates to the technical field of intelligent manufacturing equipment industry, and includes a device body, an operating table is provided at the lower end of the device body, and a cleaning device is provided on the inner outer surface of the operating table. The cleaning device includes a right opening opened on the outer surface of the right end of the operating table, a deep groove opened on the outer surface of the upper end of the operating table, a handwheel at the front end of the operating table, a rotating shaft connected to the outer surface of the rear end of the handwheel, a bearing connected to the outer surface of the rotating shaft near the rear end face, and a conveyor belt connected to the outer surface of the rotating shaft, and a clamping device is provided on the outer surface of the upper end of the operating table near the lower end of the device body.

[0003] When punching and tapping square metal parts, a grid-type pad is usually used for the bottom of the metal part. After the holes are punched, the metal wire inside the metal part will pass through and be discharged from the bottom of the metal part. However, when encountering the connection between the grid spaces, the metal wire cannot be completely discharged and is blocked at the bottom of the metal part, causing the punching and tapping pressure of the metal part to increase, and the accuracy of the tapped thread groove is greatly reduced and deformation occurs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a drilling and tapping device to achieve the purpose of solving the above-mentioned problems.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: a drilling and tapping device, including a work cabinet, a workbench is fixedly connected to the top of the work cabinet, a slide rail is fixedly connected to the top of the workbench, an electric slide is arranged on the outer wall of the slide rail, an electric lift is arranged inside the electric slide, a punching and tapping machine is fixedly connected to the outer wall of the electric lift, a drill bit is arranged at the bottom of the punching and tapping machine, and a tapping feeding mechanism is arranged on the top of the workbench; The tapping and blanking mechanism comprises: An electric telescopic rod, which is a multi-section circular rod-shaped structure, one end of which is fixedly connected to a baffle, the bottom of which is fixedly connected to the top of the workbench, and one end of which is fixedly connected to a push plate, the outer wall of which is provided with a groove A, and the electric telescopic rod is used to push the push plate to clamp the square metal piece; A groove B is provided at the bottom of the baffle plate and is used for cleaning up discarded metal wires. A connecting rod is fixedly connected to the outer wall of the punching and tapping machine, and the connecting rod is an L-shaped rod structure.

[0006] Preferably, the outer wall of the connecting rod is slidably connected with a telescopic sleeve, the inner wall of the telescopic sleeve is slidably connected with another connecting rod located below, and one end of the other connecting rod located below is fixedly connected with an annular sleeve.

[0007] Preferably, the outer wall of the annular sleeve is fixedly connected to a fixed sleeve A, the inner wall of the fixed sleeve A is slidably connected to a fixed sleeve B, and the inner wall of the fixed sleeve B is slidably connected to a sliding plate.

[0008] Preferably, the sliding plate is slidably connected to another fixing sleeve B away from the outer wall of the fixing sleeve B, the outer wall of the other fixing sleeve B is slidably connected to another fixing sleeve A, and one end of the other fixing sleeve A is slidably connected to a sliding bar.

[0009] Preferably, the outer wall of the sliding bar is fixedly connected to the outer wall of the baffle, the top of the annular sleeve is rotatably connected to a rotating ball A, and the top of the fixed sleeve B is rotatably connected to a rotating ball B.

[0010] Preferably, a rotating ball C is rotatably connected to the top of the sliding plate, and an auxiliary mechanism is provided on the outer wall of the fixed sleeve A. The auxiliary mechanism includes a connecting plate A, and one end of the connecting plate A is fixedly connected to the outer wall of the fixed sleeve A.

[0011] Preferably, one end of the connecting plate A is fixedly connected to a connecting plate B, one end of the connecting plate B is fixedly connected to the outer wall of another fixed sleeve A, the bottom of the fixed sleeve A is fixedly connected to a sealing plate A, and the bottom of the fixed sleeve B is fixedly connected to a sealing plate B.

[0012] Preferably, the sealing plates A and B are used to seal the bottom of the fixed sleeves A and B, and the inner wall of the annular sleeve is provided with air holes, and the interior of the fixed sleeve A is connected with the interior of the air holes through the annular sleeve.

[0013] The present invention provides a drilling and tapping device, which has the following beneficial effects: 1. The present invention sets a tapping and unloading mechanism. When the annular sleeve moves horizontally, it will drive the fixed sleeve A, the fixed sleeve B and the sliding plate of the outer wall to move synchronously. When the fixed sleeve A, the fixed sleeve B and the sliding plate move, the fixed sleeve B will slide on the inner wall of the fixed sleeve A, and the sliding plate will slide inside the fixed sleeve B to complete the telescopic sliding work, so that the annular sleeve can move freely, and the surrounding fixed sleeve A, the fixed sleeve B and the sliding plate can also support the metal parts placed thereon, forming a movable grille pad, so as to avoid the punching and tapping instability caused by the downward pressure generated by the punching and tapping from top to bottom when the push plates on both sides are clamped, and the movable grille support method also supports the free movement of the annular sleeve.

[0014] 2. The present invention provides a tapping feeding mechanism. When the metal part is placed on the fixed sleeve A, the fixed sleeve B, the sliding plate and the annular sleeve, it will contact the rotating ball A on the annular sleeve, the rotating ball B on the fixed sleeve B and the rotating ball C on the sliding plate. Therefore, when the metal part remains stationary and the punching and tapping machine moves horizontally to drive the fixed sleeve A, the fixed sleeve B and the sliding plate to move, the rotating ball A, the rotating ball B and the rotating ball C will roll on the top of the metal part, thereby maintaining the stable support of the fixed sleeve A, the fixed sleeve B and the sliding plate on the metal part and reducing friction to prevent the bottom of the metal part from being scratched when the fixed sleeve A, the fixed sleeve B and the sliding plate move, which may cause the quality of the metal part itself to be affected after punching and tapping.

[0015] 3. The present invention sets an auxiliary mechanism. When the fixed sleeve A, the fixed sleeve B and the sliding plate are stretched, the internal air will be replenished through the corresponding air holes, so that the air inside the annular sleeve can flow quickly. When the drill bit moves to other positions to continue tapping after punching and tapping, the metal wire that failed to fall out of the annular sleeve last time and is squeezed in the annular sleeve can be pushed away, and the shaking of the annular sleeve can prevent the metal wire from being squeezed inside the annular sleeve, thereby maintaining the stability of the waste metal wire after tapping and reducing the situation in which the tapping accuracy is affected by unnecessary pressure caused by obstructions from below during the tapping process.

DETAILED DESCRIPTION

[0018] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a drilling and tapping device, comprising a work cabinet 2, a work table 1 is fixedly connected to the top of the work cabinet 2, a slide rail 5 is fixedly connected to the top of the work table 1, an electric slide 6 is arranged on the outer wall of the slide rail 5, an electric lift 7 is arranged inside the electric slide 6, a punching and tapping machine 8 is fixedly connected to the outer wall of the electric lift 7, a drill bit 9 is arranged at the bottom of the punching and tapping machine 8, and a tapping feeding mechanism 3 is arranged on the top of the work table 1; The tapping and blanking mechanism 3 comprises: The electric telescopic rod 301 is a multi-section circular rod structure. One end of the electric telescopic rod 301 is fixedly connected to a baffle 304. The bottom of the baffle 304 is fixedly connected to the top of the workbench 1. One end of the electric telescopic rod 301 is fixedly connected to a push plate 302. The outer wall of the push plate 302 is provided with a groove A303. The electric telescopic rod 301 is used to push the push plate 302 to clamp the square metal piece. Groove B305, groove B305 is provided at the bottom of baffle 304, groove B305 is used to clean up the waste metal wire, the outer wall of punching and tapping machine 8 is fixedly connected with connecting rod 306, connecting rod 306 is an L-shaped rod structure; Place the square metal piece that needs to be punched and tapped on the workbench 1, then start the left and right electric telescopic rods 301 to push the groove A303 to clamp the metal piece, and at the same time start the electric slide 6 to control the electric lift 7 and the punching and tapping machine 8 to move freely in the horizontal direction, move the drill bit 9 under the punching and tapping machine 8 to the specified position, start the punching and tapping machine 8 to control the drill bit 9 to rotate, start the electric lift 7 to control the punching and tapping machine 8 to rise and fall in the electric slide 6, and complete the drilling and tapping machine 8 to descend to perform drilling and tapping work at the specified position; Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: the outer wall of the connecting rod 306 is slidably connected to a telescopic sleeve 315, the inner wall of the telescopic sleeve 315 is slidably connected to another connecting rod 306 located below, and one end of the other connecting rod 306 located below is fixedly connected to an annular sleeve 307.

[0019] The outer wall of the annular sleeve 307 is fixedly connected with a fixed sleeve A308, the inner wall of the fixed sleeve A308 is slidably connected with a fixed sleeve B309, and the inner wall of the fixed sleeve B309 is slidably connected with a sliding plate 310.

[0020] The sliding plate 310 is slidably connected to another fixing sleeve B309 away from the outer wall of the fixing sleeve B309, the outer wall of the other fixing sleeve B309 is slidably connected to another fixing sleeve A308, and one end of the other fixing sleeve A308 is slidably connected to the sliding bar 311.

[0021] The outer wall of the sliding bar 311 is fixedly connected to the outer wall of the baffle 304, the top of the annular sleeve 307 is rotatably connected to a rotating ball A312, and the top of the fixed sleeve B309 is rotatably connected to a rotating ball B313; When drilling and tapping, the metal piece is first placed on the fixing sleeve A308, the fixing sleeve B309, and the sliding plate 310, and then clamped by the two push plates 302. Therefore, when the drill bit 9 descends to drill and tap the metal piece, the tapped metal wire will fall from the space below the metal piece to complete the lower discharge of the metal wire. When the drill bit 9 moves horizontally, the drilling and tapping machine 8 will move with the connecting rod 306, and the upper connecting rod 306 will drive the lower connecting rod 306 to move together through the telescopic sleeve 315. The connecting rod 306 at the bottom drives the annular sleeve 307 to move, and the annular sleeve 307 drives the fixed sleeve A308 of the outer wall to move synchronously, so that no matter where the drill bit 9 and the punching and tapping machine 8 move to punch holes in the metal part, the annular sleeve 307 at the middle of the punching hole below is always centered with the punching and tapping machine 8 and the drill bit 9, so that the threaded metal wire produced after punching and tapping will naturally fall through the circular space in the middle of the annular sleeve 307, avoiding the problem that part of the tapped metal wire is blocked by the grid due to the use of a grid-shaped bottom plate at the bottom of the metal part and cannot fall, resulting in extrusion inside the tapping groove, causing a large tapping pressure, and the problem of reduced thread accuracy and deformation of the tapped thread; At the same time, when the annular sleeve 307 moves horizontally, it will drive the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 of the outer wall to move synchronously. When the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 move, the fixed sleeve B309 will slide on the inner wall of the fixed sleeve A308, and the sliding plate 310 will slide inside the fixed sleeve B309 to complete the telescopic sliding work, so that the annular sleeve 307 can move freely, and at the same time, the surrounding fixed sleeves A308, the fixed sleeve B309 and the sliding plate 310 can be used to support the metal parts placed thereon, forming a movable grille pad, so as to avoid the punching and tapping instability caused by the downward pressure generated by the punching and tapping from top to bottom when the push plates 302 on both sides are clamped, and the movable grille support method also supports the free movement of the annular sleeve 307; When the metal part is placed on the fixed sleeve A308, the fixed sleeve B309, the sliding plate 310 and the annular sleeve 307, it will contact with the rotating ball A312 on the annular sleeve 307, the rotating ball B313 on the fixed sleeve B309 and the rotating ball C314 on the sliding plate 310, so that when the metal part remains stationary and the punching and tapping machine 8 moves horizontally to drive the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 to move, the rotating balls A312, B313 and C314 will roll with the top of the metal part, while maintaining the stable support of the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 on the metal part, and reducing friction to prevent the bottom of the metal part from being scratched when the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 move, thereby causing the quality of the metal part itself to be affected after punching and tapping. Example 3: Please refer to Figure 1-12 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a rotating ball C314 is rotatably connected to the top of the sliding plate 310, an auxiliary mechanism 4 is provided on the outer wall of the fixed sleeve A308, and the auxiliary mechanism 4 includes a connecting plate A401, and one end of the connecting plate A401 is fixedly connected to the outer wall of the fixed sleeve A308.

[0022] One end of the connecting plate A401 is fixedly connected to a connecting plate B405, one end of the connecting plate B405 is fixedly connected to the outer wall of another fixed sleeve A308, the bottom of the fixed sleeve A308 is fixedly connected to a sealing plate A402, and the bottom of the fixed sleeve B309 is fixedly connected to a sealing plate B403.

[0023] The sealing plates A402 and B403 are used to seal the bottom of the fixed sleeves A308 and B309. The inner wall of the annular sleeve 307 is provided with air holes 404. The interior of the fixed sleeve A308 is connected with the interior of the air holes 404 through the annular sleeve 307. After the metal parts are placed on the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310, when the punching and tapping machine 8 and the drill bit 9 move to drive the annular sleeve 307 to move synchronously, the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 will expand and contract. Since the top of the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 are covered by metal parts and the bottom is closed by the sealing plate A402 and the sealing plate B403, a relatively closed space is formed inside. When the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 move and contract rapidly in the horizontal direction, the air inside the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 will pass through the inside of the annular sleeve 307 when the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 are contracted. When the air holes 404 are blown out and the fixed sleeve A308, the fixed sleeve B309 and the sliding plate 310 are stretched, the internal air will be replenished through the corresponding air holes 404, so that the air in the annular sleeve 307 can flow quickly, so that when the drill bit 9 moves to other positions to continue tapping after punching and tapping, the metal wire that failed to fall from the annular sleeve 307 last time and is squeezed in the annular sleeve 307 is pushed away, and the shaking of the annular sleeve 307 prevents the metal wire from being squeezed and stuck in the annular sleeve 307, thereby maintaining the stability of the waste metal wire after tapping and reducing the situation in which the tapping accuracy is affected by unnecessary pressure caused by obstructions from below during the tapping process.

[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
