Description

Technical Field

[0001] This invention relates to the field of rebar sleeve processing technology, and in particular to a tapping machine for rebar sleeve processing. Background Technology

[0002] A tapping machine is a mechanical device specifically used to machine internal threads on the inner wall of through holes or blind holes in mechanical parts. By rotating the tap, a spiral internal thread is cut on the inner wall of a pre-drilled through hole or blind hole so that screws or bolts can be screwed in firmly. It is widely used in various industrial manufacturing fields.

[0003] When tapping a rebar sleeve, the worker uses clamping blocks to clamp and fix the position of the rebar sleeve, and then rotates and lifts the tap to complete the tapping. However, after tapping, the worker usually needs to reach into the clamping jaws to get the part from the tap. If the equipment is started by mistake at this time, the worker may touch the tap, causing work-related injuries such as hand crushing or entanglement. In addition, the worker needs to stop the machine for a few seconds each time he takes out a rebar sleeve. With the accumulation of multiple workpieces, the processing efficiency is greatly reduced. Summary of the Invention

[0004] The purpose of this invention is to provide a tapping machine for processing rebar sleeves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tapping machine for processing rebar sleeves, comprising a frame; A tapping mechanism is disposed above the frame and is used to tap the rebar sleeve. A fixed frame is fixedly connected to the outer wall of the machine frame. A fixed plate is fixedly connected to the inner wall of the fixed frame. A second clamping block is fixedly connected to the inner wall of the fixed plate. A rotatable support mechanism is provided outside the second clamping block. A rotation drive mechanism is provided outside the support mechanism.

[0006] Preferably, a first clamping block is slidably connected to the inner wall of the fixing plate, and the tapping mechanism is fixedly installed inside the fixing frame.

[0007] Preferably, the support mechanism includes: A connecting block is fixedly connected to the outer wall of the second clamping block, and a connecting shaft is rotatably connected to the inner wall of the connecting block; A support plate is fixedly sleeved on the outer wall of the connecting shaft, and a clamping plate is fixedly connected to the outer wall of the square block, with the support plate clamped to the inner wall of the clamping plate.

[0008] Preferably, the rotary drive mechanism includes: A support rod is fixedly connected to the outer wall of the square block, and an extrusion plate is fixedly connected to the end of the support rod away from the square block; A torsion spring is fixedly connected between the support plate and the connecting block.

[0009] Preferably, a first driving component is fixedly installed on the outside of the frame, and the first driving component is used to drive the first clamping block to move.

[0010] Preferably, the collection mechanism includes: A trapezoidal block, which is slidably connected to the inner wall of the frame; A collection tray is movably disposed above a trapezoidal block, and an elastic component is disposed on the outside of the trapezoidal block.

[0011] Preferably, the elastic component includes: A circular rod, which is slidably connected to the inner wall of the frame; A spring, which is fixedly connected between the frame and the trapezoidal block.

[0012] Preferably, a second driving component is fixedly connected to the inner wall of the frame, and a square plate is fixedly connected to the output shaft of the second driving component.

[0013] Preferably, the material guiding mechanism includes: The feeding plate is fixedly connected to the inner wall of the frame; A cover plate, which is hinged to the inner wall of the frame.

[0014] Preferably, there are multiple trapezoidal blocks arranged horizontally at intervals, the inner wall of each trapezoidal block is rotatably connected to a roller, and the inner wall of the collection tray is fixedly connected to a top rod.

[0015] The technical effects and advantages of this invention are as follows: 1. In the processing of this invention, a tapping mechanism is used to cut the inside of the rebar sleeve. When the tapping mechanism descends and approaches the rebar sleeve, a rotary drive mechanism drives the support mechanism to rotate until the support mechanism forms a support platform. The worker places the rebar sleeve on the support platform. After processing is completed, the support mechanism reverses until the support mechanism no longer supports the rebar sleeve, and the rebar sleeve falls automatically, thus achieving human-machine isolation.

[0016] 2. In the process of the rebar sleeve falling, the present invention uses a collection mechanism to automatically collect the falling rebar sleeve. After the rebar sleeve is collected, the worker can take it out at once without having to bend over for a long time, which further saves the worker's physical exertion. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figures 1-6 The image shows a tapping machine used for processing rebar sleeves.

[0021] Example 1: Includes a frame 1, a tapping mechanism 2, and a fixing frame 3. The tapping mechanism 2 is located above the frame 1 and is used for tapping rebar sleeves. The fixing frame 3 is fixedly connected to the outer wall of the frame 1. A fixing plate 6 is fixedly connected to the inner wall of the fixing frame 3. A second clamping block 7 is fixedly connected to the inner wall of the fixing plate 6. A rotatable support mechanism is provided outside the second clamping block 7. A rotary drive mechanism is provided outside the support mechanism. The tapping mechanism 2 includes a hydraulic cylinder, a servo motor, and a tap. The hydraulic cylinder is controlled by an electronic control system and a pump body. The hydraulic cylinder drives the servo motor and the tap to move up and down. The servo motor is used to drive the tap. During the machining process, the hydraulic cylinder drives the servo motor and tap to move downwards. The servo motor then drives the tap to rotate, causing it to descend along the through-hole of the rebar sleeve, cutting threads into the inner wall of the through-hole. After machining, the tap is reversed, and the hydraulic cylinder drives it to move upwards, moving the tap out of the through-hole of the rebar sleeve. A first clamping block 5 is slidably connected to the inner wall of the fixing plate 6. The tapping mechanism 2 is fixedly installed inside the fixing frame 3. The first clamping block 5 cooperates with the second clamping block 7 to clamp and fix the rebar sleeve. A sliding groove is provided inside the fixing plate 6, and the first clamping block 5 slides into the groove. The fixed plate 6 supports the first clamping block 5 and the second clamping block 7, and the adjacent surfaces of the first clamping block 5 and the second clamping block 7 are both set as V-shaped clamping surfaces. The V-shaped clamping surfaces allow the first clamping block 5 and the second clamping block 7 to be used with rebar sleeves of different sizes while automatically centering the rebar sleeves, improving processing accuracy. A first driving component 4 is fixedly installed externally on the frame 1. The first driving component 4 is used to drive the first clamping block 5 to move. The first driving component 4 uses an existing electro-hydraulic rod. The first driving component 4 electrically moves the first clamping block 5 closer to or further away from the second clamping block 7. In specific use: during the processing, the tapping mechanism... 2. The inside of the rebar sleeve is machined. When the tapping mechanism 2 descends and approaches the rebar sleeve, the rotary drive mechanism drives the support mechanism to rotate until the support mechanism forms a support platform. The worker places the rebar sleeve on the support platform. After the machining is completed, the support mechanism reverses until the support mechanism no longer supports the rebar sleeve, and the rebar sleeve falls automatically, realizing human-machine isolation. The collecting mechanism automatically collects the fallen rebar sleeve, so the worker does not need to bend over for a long time to pick it up, further saving the worker's physical exertion. Moreover, the rebar sleeve falls automatically after each machining, without stopping the equipment, which can greatly improve the working efficiency of the equipment.

[0022] One aspect of the support mechanism includes a connecting block 13 and a support plate 10. The connecting block 13 is fixedly connected to the outer wall of the second clamping block 7. A connecting shaft 12 is rotatably connected to the inner wall of the connecting block 13. The support plate 10 is fixedly sleeved on the outer wall of the connecting shaft 12. A clamping plate 16 is fixedly connected to the outer wall of the square block 15. The support plate 10 is clamped to the inner wall of the clamping plate 16. The rotation drive mechanism includes a support rod 14 and a torsion spring 11. The support rod 14 is fixedly connected to the outer wall of the square block 15. A pressing plate 9 is fixedly connected to one end of the support rod 14 away from the square block 15. The torsion spring 11 is fixedly connected between the support plate 10 and the connecting block 13. There are two clamping plates 16, which are spaced apart vertically. The gap between the two clamping plates 16 can engage with the outer wall of the support plate 10. The clamping plates 16 can fix the position of the support plate 10. The support rod 14 can engage with the pressing plate 9 to press the support plate 10, causing the support plate 10 to rotate around the connecting shaft 12. When the bottom of the pressing plate 9 is in contact with the support plate 10, the support plate 10 is in a horizontal state. Furthermore, the gaps between the support plate 10 and the two clamping plates 16 are opposite, and the support plate 10 can be clamped between the two clamping plates 16. In specific use: when it is necessary to process the steel bar sleeve, the worker starts the first driving component 4, and the first driving component 4 drives the first clamping block 5 to move. The first clamping block 5 drives the square block 15 to move synchronously. The square block 15 drives the support rod 14 and the pressing plate 9 to move synchronously. The support rod 14 and the pressing plate 9 press the support plate 10, and the support plate 10 rotates around the connecting shaft 12. The support plate 10 twists the torsion spring 11 until the support plate 10 rotates to a horizontal state. The first clamping block 5 continues to drive the clamping plate 16 to move until the support plate 10 is clamped inside the clamping plate 16. The clamping plate 16 fixes the support plate 10. The worker places the rebar sleeve between the first clamping block 5 and the second clamping block 7. The first clamping block 5 continues to move so that the first clamping block 5 and the second clamping block 7 clamp and fix the rebar sleeve. The tapping mechanism 2 completes the processing of the rebar sleeve. After the processing is completed, the first clamping block 5 drives the square block 15 to move in the opposite direction until the clamping plate 16 and the support plate 10 are unclamped. The torsion spring 11 resets and drives the support plate 10 to reverse. The support plate 10 no longer supports the rebar sleeve, and the rebar sleeve falls automatically, saving the worker the process of manually removing the rebar sleeve.

[0023] Example 2: Example 2 further discloses, based on Example 1, that the collection mechanism includes a trapezoidal block 20 and a collection tray 18. The trapezoidal block 20 is slidably connected to the inner wall of the frame 1, and the collection tray 18 is movably disposed above the trapezoidal block 20. An elastic component is disposed outside the trapezoidal block 20, the elastic component including a circular rod 22 and a spring 21. The circular rod 22 is slidably connected to the inner wall of the frame 1, and the spring 21 is fixedly connected between the frame 1 and the trapezoidal block 20. A second driving member 24 is fixedly connected to the inner wall of the frame 1, and a square plate 23 is fixedly connected to the output shaft of the second driving member 24. The material guiding mechanism includes a feeding plate 8 and a cover plate 17. The feeding plate 8 is fixedly connected to the inner wall of the frame 1, and the cover plate 17 is hinged to the inner wall of the frame 1. There are multiple trapezoidal blocks 20 arranged horizontally at intervals. Rollers 25 are rotatably connected to the inner wall of block 20, and top rods 19 are fixedly connected to the inner wall of collection tray 18. There are two collection trays 18, which are arranged vertically and horizontally. The upper collection tray 18 is used to collect the steel sleeves that slide down from the feed plate 8. The trapezoidal blocks 20 are arranged in pairs, vertically and horizontally, with one collection tray 18 positioned opposite the feed plate 8. The steel sleeves that slide down from the feed plate 8 can slide into this collection tray 18. The lower collection tray 18 is placed on top of the square plate 23, and the bottom of the upper collection tray 18 is in contact with the top of the lower trapezoidal block 20. The trapezoidal block 20 has a smooth inclined surface. A deep groove is opened inside the frame 1, and the trapezoidal block 20 can slide horizontally along the deep groove inside the frame 1. The trapezoidal block 20 supports the collection tray 18, and the lower collection tray 18 is placed on the square plate 23. Above plate 23, and at the position opposite to trapezoidal block 20, there is an inclined surface parallel to the inclined surface of trapezoidal block 20. During the upward movement of collection plate 18, the inclined surface of collection plate 18 presses against the inclined surface of trapezoidal block 20. The outer inclined surface of collection plate 18 can press trapezoidal block 20 to slide horizontally along the inner wall of frame 1. When trapezoidal block 20 moves into the inner part of frame 1, it compresses spring 21. When collection plate 18 and the inclined surface of trapezoidal block 20 are not in contact, spring 21, under the action of restoring its natural state, presses trapezoidal block 20 to move in the opposite direction. When the lower collection plate 18 moves upward, the top rod 19 can press the upper collection plate 18, so that the two collection plates 18 move upward synchronously, so that the upper collection plate 18 presses against the upper trapezoidal block 20, and the upper collection plate 18 moves onto the upper trapezoidal block 20. When the trapezoidal block 20 resets, it moves between the two collecting trays 18. At this time, the lower collecting tray 18 descends, the upper collecting tray 18 remains above the upper trapezoidal block 20, and the lower collecting tray 18 remains below the lower trapezoidal block 20. This allows the lower collecting tray 18 to continue collecting rebar sleeves, while the upper collecting tray 18 stops collecting rebar sleeves. Workers can then open the cover plate 17 to remove the upper collecting tray 18, eliminating the need for workers to remove the rebar sleeves from inside the frame 1 and further improving work efficiency. The feeding plate 8 is used to guide the rebar sleeves, and the falling rebar sleeves roll off the feeding plate 8 into the collecting tray 18. The second driving component 24 is a commercially available electro-hydraulic rod, and the frame 1 has an internal mounting slot. The second driving component 24 is located inside the mounting slot.The second drive unit 24 drives the square plate 23 to lift the collection tray 18. By opening the cover plate 17, the worker can remove the collection tray 18 inside the frame 1 and place a new collection tray 18. In specific use: after processing is completed, the support plate 10 rotates and no longer supports the rebar sleeve. The rebar sleeve falls to the top of the feeding plate 8 and rolls down through the feeding plate 8 into the upper collection tray 18. After the upper collection tray 18 has finished collecting, the worker starts the second drive unit 24. The second drive unit 24 drives the square plate 23 to move, and the square plate 23 drives the lower collection tray 18 to move. The lower collection tray 18 drives the upper collection tray 18 to move through the top rod 19. The upper collection tray 18 rises and moves, and the top inclined surface of the upper collection tray 18 presses against the outer inclined surface of the trapezoidal block 20. The collection tray 18 is squeezed... Trapezoidal block 20 moves horizontally, compressing spring 21 until the upper collecting tray 18 moves above it. Spring 21 then returns to its natural state, compressing trapezoidal block 20 and causing it to move in the opposite direction. Trapezoidal block 20 moves below the upper trapezoidal block 20, and the lower collecting tray 18 moves above it. At this time, the second driving component 24 drives the lower collecting tray 18 to move in the opposite direction. The upper collecting tray 18 is supported by the upper trapezoidal block 20, and the lower collecting tray 18 is supported by the lower trapezoidal block 20. The lower collecting tray 18 continues to collect the steel sleeves that slide off the feeding plate 8. Workers can open the cover plate 17, remove the upper collecting tray 18, and place the new collecting tray 18 on top of the square plate 23, thus achieving automatic replacement of the receiving collecting tray 18 and further reducing worker collection costs.
