TECHNICAL FIELD

[0001] The present application relates to the technical field of turning processing, in particular to a prefabricated cabinet processing turning device. BACKGROUND

[0002] As an important choice for modern kitchen decoration, prefabricated cabinets are gradually becoming a mainstream trend due to their factory prefabrication, rapid installation and high cost performance. Adopting factory prefabrication mode can reduce on-site construction pollution and garbage emission, which is in line with the concept of green and low carbon. For example, the assembly type interior technology of Huanaizhuang is an energy-saving and environment-friendly technology realized through industrialized component systems. Prefabricated cabinets meet the standardization requirements, while customized cabinets are designed for special house types or functional requirements. Prefabricated cabinets can be installed within 1-2 weeks, while customized cabinets need 4-8 weeks. Prefabricated cabinets balance function and cost through industrialized production and are the practical choice for most families.

[0003] In the prior art, the shaft hardware inside the prefabricated cabinet needs to be turned during production and processing to achieve the customized size. The existing turning equipment is generally divided into two types: manual lathe and numerical control lathe. When using a manual lathe to process the shaft hardware of a prefabricated cabinet, smaller shaft hardware requires higher tool setting. When installing the tool, the manual lathe generally raises the tool handle by using shims to keep the cutting edge of the tool and the center of the shaft part horizontal. At this time, since the size of the part is small and the thickness of the shim is fixed, the worker needs to frequently replace shims of different thicknesses for testing to keep the tool and the shaft center aligned. In this process, the worker needs to spend a lot of time, and when the turning tool is damaged and needs to be replaced, the shim needs to be adjusted again, which will affect the processing effect.

[0013] Preferably, the top surface of the base is provided with a connecting groove, a bearing is fixedly sleeved on the inner circular wall surface of the connecting groove, the base is rotatably connected with the tool holder through the bearing, the inside bottom surface of the connecting groove is provided with a second threaded groove, the inner circular wall surface of the second threaded groove is threadedly connected with the fastening threaded shaft, the top surface of the base is provided with a plurality of second positioning grooves, a fourth spring is movably sleeved on the inner circular wall surface of the second positioning groove, a pressing block is slidably connected in the second positioning groove, a limiting block is fixedly installed on the top surface of the pressing block, and the bottom surface of the tool holder is provided with a plurality of second limiting grooves, the inner circular wall surface of the second limiting groove is movably sleeved with the limiting block.

[0020] By adopting the above technical solution, cutting waste and cutting fluid are prevented from entering the interior of the molding and mounting cavity and causing jamming.

[0021] In summary, the present invention has the following main beneficial effects: 1. This invention drives the first lead screw by rotating the adjustment knob, which can precisely adjust the height of the pad; by rotating the receiving bolt with a wrench, the vertical movement of the pad can be converted into rotational motion, thereby adjusting the angle of the tool. This achieves rapid, independent and precise adjustment of the tool height and horizontal angle, ensuring that the tool cutting edge can be precisely aligned with the axis of the part, meeting the requirements of high-precision machining.

[0022] 2. This invention integrates a display mechanism with a pointer and scale ring into an adjustment knob, and employs a spring-loaded limit post and a limit groove cooperation structure. Pulling the knob releases the limit to adjust the height; after releasing, the limit post automatically resets and locks under the action of the spring. This makes the height adjustment quantifiable and visual (through scale readings), and automatically locks after adjustment to prevent accidental displacement, ensuring the stability and repeatability of the set parameters.

[0023] 3. After the angle adjustment is completed, the present invention provides a solid rigid support and lock for the pad and the tool on it by tightening multiple limiting threaded tubes to secure them to the positioning frame. This effectively prevents the angle from shifting when the processing force is applied, and ensures the stability and safety of the processing process.

[0024] 4. This invention allows the pressure plate to move upward by pulling and rotating the lever; after the tool holder is inserted, rotating the lever in the opposite direction causes the pressure plate to automatically press down under the action of the spring, temporarily pressing the tool holder against the pad. Finally, the fixing bolts are screwed in for final locking, achieving quick installation and initial pre-fixation of the tool, facilitating subsequent fine-tuning; after adjustment, final rigid fixation can be achieved, balancing operational efficiency and clamping reliability.

[0025] 5. With this invention, the entire tool holder can rotate after the fastening threaded shaft is loosened. During rotation, the limiting block engages with the second limiting groove at different positions under the action of the spring, and can achieve accurate positioning and pre-locking at each station through the limiting mechanism, preventing deviation and greatly enhancing the flexibility and versatility of the equipment.

[0026] 6. This invention features a modular design for the adjustment box. The entire box can be removed from the tool holder by removing the connecting bolts, facilitating cleaning and maintenance. During reinstallation, a sealing ring is achieved through frame compression, making internal inspection and maintenance of the core adjustment mechanism extremely convenient. This also ensures the sealing of the mating surfaces, effectively preventing the intrusion of coolant and metal debris, extending the equipment's service life and maintaining accuracy.

[0029] 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.

[0030] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A turning device for processing prefabricated cabinets includes: a manual lathe body 1; a base 2 is fixedly installed on the top surface of the slide box of the manual lathe body 1; a tool holder 3 is provided on the top surface of the base 2; several first mounting slots 4 are opened on the inner bottom surface of the tool holder 3; an adjusting box 5 is rotatably connected inside the first mounting slots 4; a pad 6 is provided on the top surface of the adjusting box 5; a fastening threaded shaft 10 is movably sleeved on the inner circular wall of the tool holder 3; the outer circular wall of the fastening threaded shaft 10 is threaded; the adjusting box 5 is fixedly installed to the tool holder 3 by hexagonal bolts; a receiving hole 16 is opened on the top surface of the adjusting box 5; an adjusting frame 15 is movably sleeved inside the receiving hole 16; the top surface of the adjusting frame 15 is rotatably connected to the pad 6; two slide rails 19 are fixedly installed on the inner bottom surface of the adjusting box 5; the adjusting box... The internal rotating connection of the adjustment box 5 is a first lead screw 13, one end of which is provided with an adjustment knob 14. The outer circular wall of the first lead screw 13 is threadedly connected to an adjustment seat 18. The top surface of the adjustment seat 18 is inclined. The inner top surface of the adjustment frame 15 is also inclined. The adjustment seat 18 is slidably connected to the slide rail 19. Several guide rods 23 are fixedly installed on the inner top surface of the adjustment box 5. The outer circular wall of the guide rods 23 is movably sleeved with the adjustment frame 15. One side of the adjustment box 5 is open. The top surface of the pad 6 is provided with a disassembly bolt 26. The top surface of the adjustment frame 15 is fixedly installed with a mounting cap 27. The inner circular wall of the mounting cap 27 is slidably connected to a first connecting post 28. The outer circular wall of the first connecting post 28 is movably sleeved with a first spring 29. The top surface of the first connecting post 28 is provided with a first... The threaded groove 30 and the disassembly bolt 26 are threaded through the pad 6 and connected to the inner circular wall of the first threaded groove 30. The bottom surface of the pad 6 is rotatably connected to the threaded cap 39, and the top surface of the adjusting bracket 15 is rotatably connected to the receiving bolt 24. The outer circular wall of the receiving bolt 24 is threadedly connected to the inner circular wall of the threaded cap 39. When it is necessary to align the tool with the axis of the part, the operator places the tool holder on the top of the pad 6, and then rotates the adjusting knob 14 to drive the first lead screw 13 to rotate. Then, under the threaded transmission of the first lead screw 13, the adjusting seat 18 will move accordingly. At this time, the inclined surface at the top of the adjusting seat 18 will push the inclined surface inside the adjusting bracket 15 to move it upward. Then the pad 6 will move upward accordingly, and will also move the tool holder on its top. The tool holder and tool height can be adjusted freely by moving the tool holder. When the tool holder surface is not flat, the operator can use a wrench to turn the receiving bolt 24. Under the thread transmission action of the receiving bolt 24 and the threaded cap 39, the threaded cap 39 will move away from the outside of the receiving bolt 24 and drive the pad 6 to move. At this time, the upward moving force of the pad 6 will be converted into rotational force due to its connection with the adjusting bracket 15. Then, the pad 6 will drive the tool holder and tool on its top to rotate, so that the tool cutting angle can be adjusted when the tool holder is uneven, so that it is kept horizontal with the axis of the part. This achieves the effect of quickly adjusting the usage height and usage angle of the tool and tool holder. One end of the first lead screw 13 is provided with a first positioning groove 34.A second connecting post 35 is slidably connected inside the first positioning groove 34. A second spring 36 is movably sleeved on the outer circular wall of the second connecting post 35. One end of the second connecting post 35 is fixedly installed with the adjusting knob 14. A scale ring 31 is fixedly installed on one side of the adjusting box 5. A pointer 32 is fixedly installed on the outer circular wall of the adjusting knob 14. Several limiting posts 33 are fixedly installed on one side of the adjusting knob 14. Several first limiting grooves 25 are opened on one side of the adjusting box 5. The inner circular wall of the first limiting groove 25 is movably sleeved with the limiting post 33. This is for the use of the pad 6. When adjusting the height, the operator pulls the adjustment knob 14, causing the second connecting post 35 to move and compress the second spring 36. Then, multiple limiting posts 33 move out of the multiple first limiting grooves 25, at which point the limiting effects of the multiple limiting posts 33 are engaged. The operator can then use the adjustment knob 14 to rotate the first lead screw 13. During this process, the interaction between the pointer 32 and the scale ring 31 allows the operator to determine the amount of height adjustment for the pad 6. After the height of the pad 6 is adjusted, the operator releases the adjustment knob. 14. Subsequently, the rebound force of the second spring 36 will drive the adjustment knob 14 and multiple limiting posts 33 to reset. Then, the multiple limiting posts 33 will re-enter the interior of multiple first limiting grooves 25 and limit the adjustment knob 14. This allows the operator to know the adjustment amount of the height of the pad 6 and to limit and fix the pad 6 after adjustment. Several positioning brackets 20 are installed on the top surface of the adjustment box 5, and several limiting threaded tubes 37 are fixedly installed on the bottom surface of the pad 6. Each limiting threaded tube 37 and one positioning bracket 20 are... A set of limiting threaded tubes 37 are movably fitted onto the outer wall of the positioning frame 20. The inner wall of the limiting threaded tubes 37 is threaded with fastening bolts 38. When the operating angle of the pad 6 is adjusted by rotation, the multiple limiting threaded tubes 37 move up and down inside the multiple positioning frames 20. After the operating angle of the pad 6 is adjusted, the operator screws the multiple limiting threaded tubes 37 into the interior of the multiple limiting threaded tubes 20, thereby fixing the operating position of the pad 6. This allows for limiting and fixing the pad 6 after its operating angle is adjusted.

[0031] Based on the above embodiments, refer to Figure 7 , Figure 8 , Figure 9 and Figure 10The top surface of the tool holder 3 has several second mounting slots 17. A receiving post 41 is movably fitted inside each second mounting slot 17, penetrating the bottom of the second mounting slot 17. A pull rod 9 is rotatably connected to the top surface of the receiving post 41. A third spring 42 is movably fitted to the outer circular wall of the pull rod 9. The outer circular wall of the pull rod 9 is threaded. A threaded ring 40 is fixedly fitted to the inner circular wall of the second mounting slot 17, and the inner circular wall of the threaded ring 40 is threadedly connected to the pull rod 9. A pressure plate 43 is rotatably connected to the bottom surface of the receiving post 41. The top surface of the tool holder 3 has several threaded holes 7. Fixing bolts 8 are threadedly connected inside each threaded hole 7. Every two fixing bolts 8 and one pressure plate 43 form a group. When the operator places the tool handle on the pad 6 and... When the tool holder 3 is in position, the operator pulls the lever 9 upward and rotates it, causing the receiving column 41 to move the pressure plate 43 upward. Simultaneously, the external thread of the lever 9 screws into the threaded ring 40, thus fixing the working height of the lever 9 and pressure plate 43. At this point, the operator can place the tool handle on top of the pad 6. Then, the operator can rotate the lever 9 in the opposite direction to disengage the external thread from the threaded ring 40. The return force of the third spring 42 then causes the pressure plate 43 to reset. Under the action of the return force of the third spring 42, the pressure plate 43 presses down on top of the tool handle, thus limiting the downward movement of the tool after it is placed on top of the pad 6, preventing the tool from falling during adjustment. Once the tool adjustment is complete... After completion, the operator can screw the fixing bolt 8 into the threaded hole 7, and the bottom end of the fixing bolt 8 will press down on the top of the tool holder to limit and fix it. This allows for downward pressure and limitation when the tool is placed and adjusted, and also facilitates limitation and fixation after adjustment. The top surface of the base 2 has a connecting groove 46, and a bearing is fixedly sleeved on the inner circular wall of the connecting groove 46. The base 2 and the tool holder 3 are rotatably connected through the bearing. The bottom surface of the connecting groove 46 has a second threaded groove 47, and the inner circular wall of the second threaded groove 47 is threadedly connected to the fastening threaded shaft 10. The top surface of the base 2 has several second positioning grooves 54, and a fourth spring 55 is movably sleeved on the inner circular wall of the second positioning groove 54. The internal sliding connection of the tool holder 4 includes a pressure block 56. A limit block 45 is fixedly installed on the top surface of the pressure block 56. Several second limit grooves 44 are opened on the bottom surface of the tool holder 3. The inner circular wall of the second limit groove 44 is movably sleeved with the limit block 45. By rotating the fastening threaded shaft 10 out of the interior of the second threaded groove 47, the fixation between the base 2 and the tool holder 3 can be released. Then, the operator can rotate the tool holder 3 to adjust the multiple adjustment boxes 5 and pads 6 inside. During this process, the multiple limit blocks 45 will repeatedly leave and enter the interior of the multiple second limit grooves 44 under the action of the rebound force of the multiple fourth springs 55. This can limit the tool holder 3 after it is rotated and used, preventing the tool holder 3 from being misaligned with the base 2 after rotation and affecting its use.

[0032] Based on the above embodiments, refer toFigure 2 , Figure 3 and Figure 9 Each of the first mounting slots 4 has a sealing plate 11 fixedly installed on one side inside. The sealing plate 11 is movably fitted with the inner wall of the open side of the first mounting slot 4. Each of the first mounting slots 4 has a frame 12 fixedly installed on one side inside. Each of the regulating boxes 5 has a sealing groove 21 on one side. A sealing ring 22 is fixedly installed on one side inside the sealing groove 21. The inner wall of the sealing groove 21 is movably fitted with the frame 12. When jamming or jamming occurs inside the regulating box 5, the operator can remove the connecting bolts between the tool holder 3 and the regulating box 5, and then the operator can... The adjustable box 5 can be rotated to move away from the interior of the first mounting slot 4. Then, workers can clean the interior of the adjustable box 5 through the opening on its side. When the adjustable box 5 is reinstalled, the sealing plate 11 and the insert frame 12 will respectively enter the opening and the sealing groove 21. The insert frame 12 will then compress the sealing ring 22, causing it to deform and fill the gap between the first mounting slot 4 and the adjustable box 5, thus sealing the interior of the adjustable box 5. For real-time maintenance and to maintain the seal between the first mounting slot 4 and the regulating box 5, the base 2 has a molded mounting cavity 48 inside. A second lead screw 49 is rotatably connected inside the molded mounting cavity 48. A connecting frame 50 is threaded onto the outer wall of the second lead screw 49. The connecting frame 50 is slidably connected to the molded mounting cavity 48. An air supply pipe 51 is fixedly sleeved on the inner wall of the connecting frame 50. A pipe connector 52 is fixedly installed at one end of the air supply pipe 51, and two duckbill nozzles are fixedly installed at the other end of the air supply pipe 51. The nozzles are connected to the pipe via an external air pipe. Connector 52 is connected to allow external positive pressure air to be introduced into the air supply pipe 51, and then blown between the regulating box 5 and the pad 6 through the two air supply pipes 51. This can actively drive away the waste generated by the cutting tool during machining, preventing the waste generated by turning from accumulating between the regulating box 5 and the pad 6 and causing jamming. Two bellows covers 53 are fixedly installed on both sides of the inside of the base 2. One side of the bellows cover 53 is fixedly installed with the connecting frame 50 to prevent cutting waste and cutting fluid from entering the molded installation cavity 48 and causing jamming.

[0033] Working principle: Please refer to Figures 1-10As shown, when it is necessary to align the tool with the axis of the part, the operator places the tool shank on top of the pad 6, and then rotates the adjustment knob 14 to rotate the first lead screw 13. Under the threaded transmission of the first lead screw 13, the adjustment seat 18 moves accordingly. At this time, the inclined surface at the top of the adjustment seat 18 pushes against the inclined surface inside the adjustment frame 15, causing it to move upwards. Then, the pad 6 moves upwards, causing the tool shank on top of it to move as well. This allows for arbitrary adjustment of the tool shank and tool's operating height. When the surface of the tool shank is not relatively flat... Workers can use a wrench to turn the receiving bolt 24. Under the threaded transmission action of the receiving bolt 24 and the threaded cap 39, the threaded cap 39 will move away from the outside of the receiving bolt 24 and drive the pad 6 to move. At this time, the upward moving force of the pad 6 will be converted into rotational force due to its connection with the adjusting bracket 15. In turn, the pad 6 will drive the tool holder and the tool on its top to rotate. This allows the use angle of the tool cutting edge to be adjusted when the tool holder is uneven, so that it is kept horizontal with the axis of the part. This achieves the effect of quickly adjusting the use height and use angle of the tool and tool holder.
