[0001] The present invention relates to the field of tool installation equipment, and in particular to an assembled and modular tool assembly with replaceable tool heads. Background Art

[0002] As an indispensable part of machining, the tool assembly plays an important role in industrial manufacturing. During the machining and manufacturing of parts by a machine tool, different tools need to be replaced according to the machining requirements of different parts. When drilling holes in a component, different diameter tools need to be replaced according to the usage at different positions. Currently, when machining parts with different hole diameters, multiple groups of workers are usually selected, and each group operates on a single hole diameter. This results in high labor costs and large resource consumption, which is not conducive to energy conservation and environmental protection. Moreover, the steps for replacing tools are rather cumbersome, greatly affecting work efficiency. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides an assembled and modular tool assembly with replaceable tool heads, effectively solving the problems mentioned in the above background art.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

A drivable telescopic member is rotatably connected to the front end of the frame. A rotatable frame that can rotate intermittently is rotatably connected to the upper end of the guiding cylinder. A plurality of side plates are fixedly connected to the circumferential surface of the rotatable frame. Docking members that can move up and down are slidably connected to the surfaces of the side plates. Tools are detachably installed at the lower ends of the docking members. Each time the rotatable frame rotates once, a structure is formed in which one docking member moves below the telescopic member. The output end of the telescopic member can move downward to dock with the docking member and drive the tool to rotate.

[0006] Preferably, connection sliding grooves are vertically formed along the length direction on the surfaces of the side plates. Connection sliders are slidably connected to the inner sides of the connection sliding grooves.

One ends of the connection sliders facing the guiding cylinder are fixedly connected with supporting pin shafts. Guiding grooves are formed on the surface of the guiding cylinder. The supporting pin shafts are respectively slidably matched with the guiding grooves. When the rotatable frame rotates, one of the sliding plates can be driven to move below the telescopic member through the sliding fit between the guiding cylinder and the guiding grooves.

[0007] Preferably, the guiding groove includes an arc groove coaxially formed on the upper side of the guiding cylinder surface and inclined grooves formed at both ends of the arc groove. The other ends of the two inclined grooves are respectively inclined downward and connected to each other. The supporting pin shaft on the end face of the sliding plate that moves below the telescopic member is located at the connection of the two inclined grooves.

[0008] Preferably, mounting holes are formed inside the rotating frame. The mounting holes are rotationally connected to the guiding cylinder. Positioning grooves equal in number to the docking components are formed on the inner wall of the mounting holes. Each positioning groove corresponds to a docking component. A positioning tooth block that can move radially along the guiding cylinder is slidably connected to the upper end of the guiding cylinder. One ends of the positioning tooth blocks close to the axis of the guiding cylinder are respectively fixedly connected with return springs. The other ends of the return springs are respectively fixedly connected to the guiding cylinder.

The upper end of the tool is detachably connected with a connecting column. An annular groove is formed on the upper side of the surface of the connecting column. A magnetic ring that can attract the magnetic blocks is fixedly connected to the inner surface of the annular groove. After the connecting column is inserted into the mounting tube, the clamping blocks respectively move inward to engage with the annular groove through the mutual attraction of the magnetic blocks and the magnetic ring. A limiting gear is fixedly connected to the lower side of the surface of the connecting column. A limiting internal tooth ring is fixedly connected to the lower part inside the mounting tube. After the connecting column is inserted into the mounting tube, the limiting gear is engaged inside the limiting internal tooth ring.

[0010] Preferably, outer ends of the clamping blocks are respectively provided with reinforcing screws arranged radially along the mounting tube. The reinforcing screws are respectively threadedly connected to the surface of the mounting tube. Outer ends of the reinforcing screws are respectively fixedly connected with transmission rods.

[0011] The structure of the present invention is novel, ingeniously conceived, and simple and convenient to operate. Compared with the prior art, it has the following advantages: If it is necessary to replace the tool, the telescopic member can be controlled to move upward to disconnect from the docking component, and then by controlling the rotation of the rotating frame, the required tool can be controlled to move below the telescopic member for use, saving the operation steps of replacing and installing the tool, effectively saving the working time of construction workers, and improving work efficiency; when replacing the tool, the connecting column can be directly inserted into the mounting tube. Under the limitation of the clamping block, the connecting column cannot be separated from the mounting tube, realizing the docking of the connecting column and the mounting tube.

Detailed implementation manner

[0027] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0028] As Figure 1-14 shown, the present invention provides an assembled and modular tool assembly with replaceable tool heads, including a frame 1. A guiding cylinder 2 is fixedly connected to the front side of the upper end of the frame 1. A drivable telescopic component is rotatably connected to the front end of the frame 1. A rotatable frame 4 that can rotate intermittently is rotatably connected to the upper end of the guiding cylinder 2. A plurality of side plates 5 are fixedly connected to the circumferential surface of the rotatable frame 4. Docking components that can move up and down are slidably connected to the surfaces of the side plates 5. Tools 8 are detachably installed at the lower ends of the docking components respectively. Every time the rotatable frame 4 rotates once, a structure is formed in which a docking component moves to the lower part of the telescopic component. The output end of the telescopic component can move downward to dock with the docking component and drive the tool 8 to rotate; A driving motor 3 for driving the rotation of the telescopic component is fixedly connected to the upper end of the guiding cylinder 2. When the driving motor 3 rotates, it can drive the telescopic component to rotate quickly, and when the telescopic component extends downward and is connected to the docking component, the tool 8 can rotate to perform drilling operations. If it is necessary to replace the tool 8, the telescopic component can be controlled to move upward to disconnect from the docking component, and then by controlling the rotation of the rotatable frame 4, the required tool 8 can be controlled to move to the lower part of the telescopic component for use, saving the operation steps of replacing and installing the tool 8, effectively saving the working time of construction workers, improving work efficiency, and the tools 8 are all detachably connected to the docking components. When it is necessary to replace the tool 8, it can be directly replaced, which is convenient for construction workers to use and has a wide range of applications.

[0029] On the surfaces of the side plates 5, connecting sliding grooves are vertically formed along the length direction. Inside the connecting sliding grooves, connecting sliders are respectively slidably connected. At the ends of the connecting sliders far from the guiding cylinder 2, sliding plates 6 are respectively fixedly connected. The other ends of the sliding plates 6 are respectively rotatably connected to the docking components. The sliding connection between the connecting sliders and the connecting sliding grooves can stably drive the docking components to move. At the ends of the connecting sliders facing the guiding cylinder 2, supporting pin shafts 35 are respectively fixedly connected. On the surface of the guiding cylinder 2, a guiding groove is formed. The supporting pin shafts 35 are respectively in sliding fit with the guiding groove. When the rotating frame 4 rotates, under the sliding fit between the guiding cylinder 2 and the guiding groove, one of the sliding plates 6 can be driven to move below the telescopic component, facilitating the user to select the required tool 8 for use and facilitating the user's operation.

[0030] The guiding groove includes an arc-shaped groove 32 coaxially formed on the upper side of the surface of the guiding cylinder 2 and inclined grooves 33 formed at both ends of the arc-shaped groove 32. The other ends of the two inclined grooves 33 are respectively inclined downward and communicate with each other. The supporting pin shafts 35 at the end faces of the sliding plates 6 that move below the telescopic component are located at the connection of the two inclined grooves 33. When it is necessary to select and use the required tool 8, it can be selected by controlling the rotation of the rotating frame 4. When the rotating frame rotates, the supporting pin shafts 35 can slide inside the arc-shaped groove 32 and the inclined grooves 33. When the required tool 8 is moved below the telescopic component, the supporting pin shafts 35 move from the arc-shaped groove 32 to the inside of the inclined grooves 33. Under the guiding of the inclined grooves 33, they will move downward during the circumferential movement. The other tools 8 are supported by the arc-shaped groove 32 and are located on the upper side of the surface of the guiding cylinder 2 waiting for use, and do not affect the normal use of the selected tool 8.

[0031] An installation hole is formed inside the rotating frame 4. The installation hole is rotatably connected to the guiding cylinder 2. Positioning grooves 31 equal in number to the docking components are formed on the inner wall of the installation hole. Each positioning groove 31 corresponds to a docking component. A positioning tooth block 29 that can move along the radial direction of the guiding cylinder 2 is slidably connected to the upper end of the guiding cylinder 2. At the ends of the positioning tooth block 29 close to the axis of the guiding cylinder 2, return springs 30 are respectively fixedly connected. The other ends of the return springs 30 are respectively fixedly connected to the guiding cylinder 2. The ends of the positioning tooth block 29 far from the axis are respectively engaged with the corresponding positioning grooves 31. The positioning tooth block 29 brakes the rotating frame 4 by being engaged with the positioning grooves 31 under the push of the return spring 30. When it is necessary to select which tool 8, the rotating frame 4 can be controlled to rotate so that the positioning tooth block 29 is engaged with the positioning groove 31 corresponding to the selected tool 8. Then the corresponding tool 8 can be moved below the telescopic component, facilitating the user's operation and use.

[0032] The docking component includes an installation pipe 7 rotatably connected to the sliding plate 6. A plurality of clamping blocks 11 are respectively slidably connected to the inner side of the installation pipe 7. The inner ends of the clamping blocks 11 are respectively fixedly connected with magnetic blocks 14. The upper end of the cutter 8 is detachably connected with a connecting column 9. An annular groove 10 is formed in the upper side surface of the connecting column 9. A magnetic ring 13 capable of attracting the magnetic block 14 is fixedly connected to the inner side surface of the annular groove 10. After the connecting column 9 is inserted into the installation pipe 7, the magnetic blocks 14 respectively move inward due to the mutual attraction between the magnetic blocks 14 and the magnetic ring 13 to engage with the annular groove 10. A limiting gear 15 is fixedly connected to the lower side surface of the connecting column 9. A limiting internal gear ring 16 is fixedly connected to the lower inner side of the installation pipe 7. After the connecting column 9 is inserted into the installation pipe 7, the limiting gear 15 engages with the inner side of the limiting internal gear ring 16. When the installation pipe 7 rotates after the limiting gear 15 engages with the limiting internal gear ring 16, the connecting column 9 can be driven to rotate, and then the cutter 8 is driven to rotate by the connecting column 9. After the connecting column 9 is inserted into the installation pipe 7 and the clamping blocks 11 engage with the annular groove 10 under the mutual attraction between the magnetic blocks 14 and the magnetic ring 13, the connecting column 9 cannot be separated from the installation pipe 7 under the limitation of the clamping blocks 11, realizing the docking between the connecting column 9 and the installation pipe 7. The operation is simple and convenient. The connecting column 9 can be directly inserted into the installation pipe 7, which can effectively save the installation time of the cutter 8.

[0033] Furthermore, in order to improve the firmness when the connecting column 9 is connected to the installation pipe 7, reinforcing screws 12 arranged along the radial direction of the installation pipe 7 are respectively provided at the outer ends of the clamping blocks 11. The reinforcing screws 12 are respectively threadedly connected to the surface of the installation pipe 7. The outer ends of the reinforcing screws 12 are respectively fixedly connected with transmission rods 17. The surface of the transmission rod 17 is spline-connected with a transmission cylinder 20. The surface of the transmission cylinder 20 is rotatably connected with a mounting plate 19. The other ends of the mounting plates 19 are respectively fixedly connected with the installation pipe 7. Connecting bevel gears 18 are respectively fixedly connected to the surface of the transmission cylinder 20. One driving bevel gear 21 is engaged with the lower sides of the plurality of connecting bevel gears 18. The driving bevel gear 21 is rotatably connected with the installation pipe 7. A rotating ring 22 is coaxially and fixedly connected to the lower end of the driving bevel gear 21. By controlling the rotation of the rotating ring 22, the driving bevel gear 21 can be driven to rotate. When the driving bevel gear 21 rotates, the transmission rods 17 can be driven to rotate through the engagement with the plurality of connecting bevel gears 18. A plurality of annularly distributed limiting grooves are axially formed on the circumferential surface of the transmission rod 17. A plurality of annularly distributed limiting protrusions are respectively fixedly connected to the inner side of the transmission cylinder 20. The limiting protrusions are slidably connected with the limiting grooves, so that the transmission rod 17 can axially move inside the transmission cylinder 20. When the transmission cylinder 20 rotates, the transmission rod 17 can be driven to rotate through the sliding fit between the limiting protrusions and the limiting grooves. When the transmission rod 17 rotates, the reinforcing screws 12 can be driven to rotate. When the reinforcing screws 12 rotate, they move inward under the action of being threadedly connected to the surface of the installation pipe 7 to squeeze the clamping blocks 11, which can increase the pressure between the clamping blocks 11 and the annular grooves 10, thereby improving the firmness when the connecting column 9 is connected to the installation pipe 7.

[0034] The upper and lower sides of one end of the clamping block 11 facing the annular groove 10 are respectively provided with inclined surfaces inclined outward. Under the action of the inclined surfaces, when the connecting column 9 is butted against the installation pipe 7, the connecting column 9 can be directly inserted into the installation pipe 7. When the connecting column 9 is axially moving inside the installation pipe 7 and is blocked by the clamping block 11, the clamping block 11 will be pushed outward under the action of the inclined surface on the lower side of the clamping block 11. Then, when the clamping block 11 corresponds to the annular groove 10, it will move inward under the mutual attraction of the magnetic ring 13 and the magnetic block 14 to engage with the annular groove 10. When the connecting column 9 is detached from the installation pipe 7, the reinforcing screw 12 can be detached from the contact with the clamping block 11 by controlling the rotation of the rotating ring 22, and then the connecting column 9 can be directly pulled out downward. When the connecting column 9 moves downward, the inclined surface on the upper side of the inner end of the clamping block 11 can be squeezed through the annular groove 10 to disengage the clamping block 11 from the annular groove 10, which is convenient for the installation and disassembly of the connecting column 9 and further facilitates the operation of the construction personnel.

[0035] A cylindrical groove is opened upward at the lower end of the connecting column 9. An interlocking plate 23 is rotatably connected to the upper end inside the cylindrical groove. A plurality of inclined mating grooves 28 are evenly formed on the surface of the interlocking plate 23 in a circular shape. At the lower opening of the cylindrical groove, a plurality of clamping plates 25 distributed in a circular shape are respectively slidably connected along the radial direction. The outer ends of the clamping plates 25 are respectively fixedly connected with limiting plates 26. The limiting plates 26 are respectively slidably connected to the bottom of the connecting column 9. The upper ends of the clamping plates 25 are respectively fixedly connected with mating pins 27. The mating pins 27 are respectively slidably engaged with the mating grooves 28. The clamping plates 25 are used for clamping and fixing the tool 8, so that the tool 8 can be firmly installed at the lower end of the connecting column 9. During use, the tool 8 can be directly placed inside the plurality of clamping plates 25. Under the sliding fit of the mating groove 28 and the mating pin 27, when one clamping plate 25 moves radially, the interlocking plate 23 can be driven to rotate, so that the plurality of clamping plates 25 move synchronously. A fixing screw 24 is arranged at the outer end of one of the clamping plates 25. The fixing screw 24 is threadedly connected to the surface of the connecting column 9. A knob is fixedly connected to the outer end of the fixing screw 24. When strengthening the fixing effect of the clamping plate 25 on the tool 8, the knob can be rotated. When the knob rotates, the fixing screw 24 can be driven to rotate. When the fixing screw 24 rotates, under the action of being threadedly connected to the connecting column 9, the corresponding clamping plate 25 can be pushed to move inward. Then, under the action of the interlocking plate 23, the plurality of clamping plates 25 move inward to clamp and fix the tool 8, which is convenient for construction workers to use.

[0036] The telescopic member includes a spline cylinder 38 and a spline shaft 39 spline-connected to the spline cylinder 38. The spline shaft 39 is located below the spline cylinder 38. A second pulley 37 is fixedly connected to the upper end of the spline cylinder 38. A first pulley 36 is fixedly connected to the power output end of the driving motor 3. A transmission belt is sleeved between the first pulley 36 and the second pulley 37. When the driving motor 3 rotates, the spline cylinder 38 can be driven to rotate through the transmission of the first pulley 36, the second pulley 37 and the transmission belt. When the spline cylinder 38 rotates, the spline shaft 39 can be driven to rotate. A support spring 41 is arranged inside the spline cylinder 38. Both ends of the support spring 41 are fixedly connected to the upper end of the spline shaft 39 and the upper inner end of the spline cylinder 38 respectively. The support spring 41 is used to push the spline shaft 39 downward and improve the stability of the spline shaft 39. A snap ring 40 is fixedly connected to the bottom of the spline cylinder 38. An inwardly inclined mating inclined surface 47 is provided at the lower end of the snap ring 40. A plurality of spring plates 43 evenly distributed in a ring are fixedly connected to the circumferential surface on the lower side of the spline shaft 39. Hooks 44 are fixedly connected to the upper ends of the spring plates 43 respectively. When the spring plates 43 move upward, they can be hooked on the upper end of the snap ring 40 through the hooks 44. When the hooks 44 pass through the snap ring 40, the spring plates 43 can be pushed to elastically deform and swing outward under the action of the mating inclined surface 47. Then, after the hooks 44 are hooked on the upper end of the snap ring 40, they are reset. A docking column 42 is fixedly connected to the lower end of the spline shaft 39. A docking groove 45 is opened downward in the middle of the upper end of the mounting pipe 7. When the spline shaft 39 moves downward, the docking column 42 meshes with the docking groove 45. A plurality of meshing teeth are respectively opened on the circumference of the docking groove 45. A plurality of meshing grooves meshing with the meshing teeth are respectively opened inside the docking groove 45. The docking column 42 and the docking groove 45 can be linked through the meshing of the meshing teeth and the meshing grooves. When the docking column 42 meshes with the docking groove 45, the support spring 41 can support the spline shaft 39 as a pin shaft, avoiding the up-and-down shaking of the spline shaft 39 during rotation, which affects the meshing with the docking groove 45 and the transmission to the tool 8. When replacing the tool 8, the spline shaft 39 can be controlled to move upward so that the hooks 44 are hooked on the upper end of the snap ring 40 and the support spring 41 is compressed. After the required tool 8 moves to the lower end of the spline shaft 39, the hooks 44 are controlled to disengage from the snap ring 40. Under the push of the support spring 41 and the action of gravity, the spline shaft 39 moves downward so that the docking column 42 and the docking groove 45 are meshed for the transmission of the tool 8;It is used to facilitate the user to control the multiple hooks 44 to synchronously disconnect from the snap ring 40 and improve the docking efficiency with the installation pipe 7. A control ring 46 that can axially move is slidably connected to the surface of the spline barrel 38. An inwardly inclined second inclined surface 48 is provided at the lower end of the control ring 46. When the hook 44 is hung on the upper end of the snap ring 40, the inner end of the hook 44 can be stuck in the gap formed between the second inclined surface 48 of the control ring 46 and the snap ring 40 and squeeze the second inclined surface 48, forcing the control ring 46 to move upward to the upper side of the hook 44. Then, when controlling the docking of the docking column 42 and the docking groove 45, the control ring 46 can be directly moved downward. By controlling the extrusion, the multiple hooks 44 are disconnected from the snap ring 40. Then, the spline shaft 39 can move downward under the push of the support spring 41 to make the docking groove 45 dock with the docking column 42, achieving the effect of quickly docking with the installation pipe 7, driving the cutter 8 to rotate, simplifying the operation steps, facilitating the operation of construction workers, and effectively improving the work efficiency.
