Description

Technical Field

[0001] The present invention relates to the technical field of generator cylinder cover processing, in particular to a boring and milling device used for processing the generator cylinder cover. Background Art

[0002] Generators are common large-scale machines in modern society. The quality of generators is related to many factors. The quality of the generator cylinder head seriously affects the quality and performance of the generator. The existing generator cylinder head is more commonly made of aluminum alloy, and the opening structure in the aluminum alloy generator cylinder head has a vital impact on the operation of the generator. Therefore, under the current conditions, the generator cylinder head opening structure is mostly processed by boring and milling technology.

[0003] Existing boring and milling equipment, such as that disclosed in Publication No. CN213730574U, is used for CNC machining of generator cylinder heads. This lacks a heat dissipation mechanism, which can easily cause the machining disc to generate high temperatures during machining, reducing its service life. Therefore, a water storage tank, filter, and outlet are proposed to allow for constant flushing of the machining area. The machining fluid is then purified and recycled through the V-shaped filter. However, because aluminum alloy generator cylinder heads differ from other materials, the following issues arise:

[0004] First, the melting point of aluminum alloy is relatively low. The high-speed cutting operations of boring and milling cutters require the generator cylinder head to withstand extremely large external impacts and high-temperature pressures. Under these conditions, the hardness and strength of the generator cylinder head structure will be reduced. In particular, the hole structure that is in direct contact with the boring and milling cutters may even deform and crack.

[0005] Secondly, although aluminum alloy itself has a certain degree of corrosion resistance, the boring and milling process requires the use of auxiliary solutions such as coolant, which are rich in various components that can easily cause corrosion of the generator cylinder head made of aluminum alloy. If the generator cylinder head is not treated for corrosion resistance, it will cause serious corrosion and deformation of the hole structure.

[0006] Although certain structural strengthening measures are taken for the generator cylinder head made of aluminum alloy under existing conditions, such as adding reinforcing ribs to achieve stress relief, it is still impossible to cope with the high temperature and high pressure of boring and milling cutters to achieve structural protection of the generator cylinder head. Even if solid solution treatment is used to achieve the overall temperature increase and decrease of the generator cylinder head, there is a problem of continuous heat preservation difficulty, and it is impossible to achieve continuous heat preservation of the holes to be bored and milled in the generator cylinder head. Therefore, it is difficult to ensure the structural strength of the holes to be bored and milled in the generator cylinder head through solid solution aging treatment. Summary of the Invention

[0007] The purpose of the present invention is to solve the problem in the prior art that it is difficult to perform non-destructive boring and milling integrated processing on a generator cylinder cover, and to propose a boring and milling device for processing a generator cylinder cover.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A boring and milling device for machining a generator cylinder head comprises a machine body consisting of a gantry, a load-bearing cross plate and an extended right-angle frame.

[0010] The machine body is provided with:

[0011] A boring and milling machine, comprising a compressor, is disposed at the top of a gantry and lubricated and cooled by the compressor for boring and milling the generator cylinder head bore from top to bottom;

[0012] There are two sets of limit adjustment mechanisms, each of which includes a lifting slider, a telescopic rod, and a flip set block. The two sets of limit adjustment mechanisms are horizontally mounted on the left and right ends of the generator cylinder cover through the flip set block, and the lifting slider and telescopic rod are used to vertically lift, move left and right, and flip the generator cylinder cover forward and backward;

[0013] The machine body is provided with:

[0014] A reinforcement mechanism, comprising a temperature control component and a heat preservation component for performing a solution aging treatment on the generator cylinder head, wherein the heat preservation component comprises a square Fresnel lens, and the reinforcement mechanism performs end-point temperature control on the generator cylinder head hole through the square Fresnel lens;

[0015] The load-bearing cross plate is horizontally welded to the middle end of the gantry, and the extended right-angle frame is welded to the rear side of the gantry;

[0016] The compressor output end is movably connected to a high-pressure jet located on a gantry for spraying lubricant;

[0017] The lifting slider is vertically slidably installed in the gantry, the telescopic rod is horizontally slidably installed in the lifting slider, and the flip set block is rotatably installed on the telescopic rod.

[0018] Preferably, the lifting slider is provided with a driving component for driving the telescopic rod to move left and right.

[0019] Preferably, the flip set block is provided with locking components for clamping the left and right ends of the generator cylinder cover towards each other.

[0020] Preferably, the temperature control component is arranged on the load-bearing cross plate, and the heat insulation component is arranged on the extended right-angle frame.

[0021] Preferably, the temperature control component includes an insulation box fixedly mounted on the load-bearing cross plate, and the insulation box is used to heat the generator cylinder head temperature to 155°C-193°C and cool the generator cylinder head temperature to 17°C-32°C.

[0022] Preferably, a viewing window enclosed by flat glass and corresponding to a square Fresnel lens is provided on the rear side of the thermal insulation box.

[0023] Preferably, the length and width dimensions of the square Fresnel lens are 155mm*155mm.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The present invention utilizes a gantry, a load-bearing cross plate, and an extended right-angle frame to form a machine body. The gantry is used to symmetrically set two sets of limit adjustment mechanisms for fixing the generator cylinder cover. At the same time, a compressor and a high-pressure jet are provided for lubricating and spraying the boring cutter and the milling cutter, thereby playing a role in cooling and lubricating the tools and reducing the damage to the generator cylinder cover hole structure caused by high-temperature friction during the operation of the boring cutter and the milling cutter.

[0026] 2. The present invention utilizes a lifting slider, a telescopic rod, and a flip set block to form a limit adjustment mechanism, wherein a driving assembly is utilized to enable the telescopic rod and the flip set block to perform preliminary set and displacement adjustment on the generator cylinder cover through horizontal movement, while realizing the opening and closing control of the locking assembly, thereby ensuring that the generator cylinder cover can be displaced left and right, lifted vertically, and flipped forward and backward according to the requirements of solution aging treatment and boring and milling processing.

[0027] 3. The present invention opens a sleeve cavity in the flip sleeve block, and arranges a T-shaped elastic resistance piece in the sleeve cavity to resist the end of the generator cylinder head. The T-shaped elastic resistance piece is used to trigger the start of the boost plug-in to symmetrically clamp the generator cylinder head. At the same time, the elastic pin is used to perform unidirectional limiting on the limiting ratchet, so that the positioning tool can prevent the boost plug-in in the clamping state from resetting and ensure stability during the process of clamping the generator cylinder head and entering and exiting the insulation box.

[0028] 4. The present invention sets a temperature control component whose main body is an insulation box on the load-bearing cross plate. By placing the generator cylinder head fixed by the limit adjustment mechanism in the insulation box, the generator cylinder head can be heated by using a heat conductor, and can be cooled by using the lower cavity and the heat dissipation louvers. At the same time, through artificial light sources, square Fresnel lenses and visual windows, the holes to be bored and milled in the generator cylinder head in the insulation box can be continuously focused and irradiated, thereby realizing end-point solid solution aging treatment. After the heating, insulation and cooling treatments, the hole structure of the generator cylinder head can effectively improve the structural strength, hardness, fatigue resistance and corrosion resistance, and avoid deformation and cracking of the hole structure of the generator cylinder head caused by high-temperature pressurization of the boring cutter and milling cutter.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Reference Figures 1-10 A boring and milling device for processing generator cylinder heads includes a body 1 consisting of a gantry 11, a load-bearing cross plate 12 and an extended right-angle frame 13. The load-bearing cross plate 12 is horizontally welded to the middle end of the gantry 11, and the extended right-angle frame 13 is welded to the rear side of the gantry 11.

[0051] The machine body 1 is provided with a boring and milling machine 2 and a limit adjustment mechanism 3 through a gantry 11:

[0052] The boring and milling machine 2 includes a compressor 23, and the boring and milling machine 2 is arranged at the top position of the gantry 11. The output end of the compressor 23 is movably connected to a high-pressure jet 24 located on the gantry 11 for spraying lubricant. The boring and milling machine 2 that realizes lubrication and cooling through the compressor 23 is used for boring and milling the generator cylinder head holes from top to bottom. The compressor 23 and the high-pressure jet 24 are located in the middle position of the gantry 11. It should be noted that the air and lubricant are compressed by the compressor 23, and the high-pressure jet 24 that can be vertically lifted and horizontally rotated is used to cool and lubricate the boring cutter group 21 and the milling cutter group 22 to avoid high-temperature conduction and pressure damage to the generator cylinder head holes caused by the high-speed running boring cutter group 21 and the milling cutter group 22.

[0053] The boring and milling machine 2 also includes a boring cutter group 21 and a milling cutter group 22. The boring cutter group 21 and the milling cutter group 22 are symmetrically arranged about the mid-vertical line of the gantry 11. The boring cutter group 21 and the milling cutter group 22 are mature technical means commonly used in the field to which this technology belongs, so they are not described in detail.

[0054] There are two groups of limit adjustment mechanisms 3, which include a lifting slider 31, a telescopic rod 32 and a flip set block 33. The two groups of limit adjustment mechanisms 3 are horizontally mounted on the left and right ends of the generator cylinder head through the flip set block 33, and the generator cylinder head is adjusted vertically by the lifting slider 31 and the telescopic rod 32. It is worth noting that the gantry 11 is provided with a driving hydraulic cylinder for driving the lifting slider 31 to lift vertically. Under the control of the servo controller used in conjunction with it, the lifting slider 31 drives the generator cylinder head to adjust its height position through the telescopic rod 32 and the flip set block 33. Similarly, the telescopic rod 32 is provided with a driving motor for driving the flip set block 33 to flip forward and backward, so that the generator cylinder head can be adjusted in angle according to the needs of temperature control and boring and milling processing, that is, when the generator cylinder head hole position is facing upward, it corresponds to the boring and milling integrated machine 2, when it is facing backward, it corresponds to the insulation component 42 and the temperature control component 41, and when it is facing downward, it corresponds to the lower cavity 413 for heat dissipation and cooling.

[0055] The lifting slider 31 is provided with a driving assembly 34 for driving the telescopic rod 32 to move left and right. The driving assembly 34 includes a driving slider 341 and a steering lever 342.

[0056] The driving slider 341 is slidably installed on the lifting slider 31, and the lifting slider 31 is provided with a driving cylinder for pulling and driving the driving slider 341 to move horizontally. By controlling the horizontal movement adjustment of the driving slider 341, the steering lever 342 can be deflected left and right.

[0057] The steering lever 342 is rotatably mounted on the lifting slider 31, and a traction link 343 is pin-connected between one end of the steering lever 342 and the driving slider 341. A first traction long hole 344 is provided in the other end of the steering lever 342. A first traction bolt 345 slidably fitted into the first traction long hole 344 is integrally connected to the telescopic rod 32. Under the traction action of the steering lever 342, the telescopic rod 32 moves left and right along the lifting slider 31, so that the generator cylinder head can be preliminarily fitted using the flip fitting block 33.

[0058] The flip set block 33 is provided with a locking assembly 35 for clamping the left and right ends of the generator cylinder head towards each other. The locking assembly 35 includes a set cavity 351, a storage cavity 352, a T-shaped elastic resistance member 353, a supercharged wedge 354, a wedge traction rocker 355, a supercharged plug 356, and a positioning tool 359:

[0059] The sleeve cavity 351 is opened at the outer side of the flip sleeve block 33 and is used for preliminary sleeve installation of the left and right ends of the generator cylinder cover.

[0060] The receiving chamber 352 is formed inside the flip and sleeve block 33 , and is communicated with the sleeve chamber 351 .

[0061] The T-shaped elastic resistance member 353 is mounted in the sleeve cavity 351 and the storage cavity 352, and the T-shaped elastic resistance member 353 is used to resist the end of the generator cylinder cover mounted in the sleeve cavity 351. In the initial state, the T-shaped elastic resistance member 353 maintains a tendency to extend out of the storage cavity 352. When the two flip sleeve blocks 33 are moved toward each other, the generator cylinder cover can be used to apply pressure to the T-shaped elastic resistance member 353, causing the T-shaped elastic resistance member 353 to move toward one side of the storage cavity 352.

[0062] The boost wedge 354 is fixedly connected to one end of the T-shaped elastic resistance member 353 located in the receiving cavity 352 . The boost wedge 354 is a hollow structure so as to accommodate the built-in synchronous rack 3591 .

[0063] The wedge head traction rocker 355 is rotatably installed on the flip set block 33, and one end of the wedge head traction rocker 355 is movably abutted against the boost wedge head 354. A second traction long hole 357 is provided in the other end of the wedge head traction rocker 355. The wedge head traction rocker 355 is deflected by the pressure applied by the boost wedge head 354, thereby pulling the symmetrically arranged boost plug-ins 356 to move toward each other, thereby clamping and fixing the generator cylinder head.

[0064] The boost plug-in 356 is slidably mounted on the flip sleeve block 33 , and the boost plug-in 356 is integrally connected with a second traction bolt 358 slidably sleeved in the second traction long hole 357 .

[0065] The positioning tool 359 is set in the storage chamber 352 through the supercharging wedge 354, and the positioning tool 359 fixes the supercharging plug 356 that abuts the motor cylinder cover through the supercharging wedge 354. The positioning tool 359 includes a synchronous rack 3591, a damping shaft 3592, a driven gear 3593, a limiting ratchet 3594, and an elastic latch 3595:

[0066] The synchronization rack 3591 is integrally connected to the boost wedge head 354, the damping shaft 3592 is rotatably installed in the storage chamber 352, the driven gear 3593 is key-connected to the damping shaft 3592, and the driven gear 3593 is meshed with the synchronization rack 3591, and the limiting ratchet 3594 is key-connected to the damping shaft 3592. It should be noted that in the process of the T-shaped elastic resistance member 353 driving the synchronization rack 3591 to move through the boost wedge head 354, the damping shaft 3592 and the limiting ratchet 3594 rotate synchronously due to the meshing transmission between the synchronization rack 3591 and the driven gear 3593.

[0067] The elastic latch 3595 is rotatably installed on the boost wedge 354 through a torsion spring, and the elastic latch 3595 and the limiting ratchet 3594 are movably opposed. Under the elastic support of the torsion spring, the elastic latch 3595 always maintains a tendency to move forward and downward, thereby making active contact with each ratchet tooth of the limiting ratchet 3594, so as to facilitate one-way limiting of the rotating limiting ratchet 3594, avoiding the T-shaped elastic resistance member 353 from automatically resetting due to elasticity, and ensuring the stability of the boost wedge 354 driving the wedge to pull the rocker arm 355 to the boost plug-in 356 to clamp the generator cylinder head.

[0068] It is worth noting that when it is necessary to release the limit on the generator cylinder cover, the elastic pin 3595 is squeezed away from one end of the limit ratchet 3594 on the flip sleeve block 33, so that the elastic pin 3595 stops limiting the limit ratchet 3594. At this time, the T-shaped elastic resistance member 353 can be reset by its own elasticity.

[0069] The machine body 1 is provided with a reinforcement mechanism 4 through a load-bearing transverse plate 12 and an extended right-angle frame 13:

[0070] The reinforcement mechanism 4 includes a temperature control component 41 and a heat preservation component 42 for performing solution aging treatment on the generator cylinder head. The heat preservation component 42 includes a square Fresnel lens 424 , and the reinforcement mechanism 4 performs end-point temperature control on the generator cylinder head hole through the square Fresnel lens 424 .

[0071] The temperature control assembly 41 includes an insulation box 411 fixedly mounted on the load cross plate 12. The insulation box 411 is used to heat the generator cylinder head to a temperature of 155°C-193°C and cool the generator cylinder head to a temperature of 17°C-32°C. The temperature control assembly 41 also includes an upper chamber 412, a lower chamber 413, a guide notch 414, heat dissipation louvers 415, a heat conducting member 416, and a heat shield 417.

[0072] The insulation box 411 is fixedly installed on the load-bearing cross plate 12. The generator cylinder head is built into the insulation box 411 to facilitate heating, sealing and cooling treatments. The generator cylinder head holes are subjected to targeted insulation treatments in the relatively closed insulation box 411, thereby improving the stability of the insulation state of the generator cylinder head and helping to reduce the diffusion and loss of high-temperature heat.

[0073] It should be noted that after the generator cylinder head is symmetrically clamped and fixed by the locking assembly 35, the state of the generator cylinder head is adjusted using the limit adjustment mechanism 3 according to the needs of heating, insulation, cooling and boring and milling processing, so that the generator cylinder head can be raised and lowered in height, flipped front and back, and translated left and right in the insulation box 411.

[0074] The upper chamber 412 is opened at the upper end of the heat preservation box 411 , and the rear side of the lower end of the upper chamber 412 is connected to the viewing window 418 .

[0075] The lower chamber 413 is opened at the lower end of the insulation box 411. It should be noted that a ventilation hole connecting the upper chamber 412 and the lower chamber 413 is opened at the middle end of the insulation box 411, and a radiator is provided in the lower chamber 413. When the generator cylinder head needs to be cooled, the generator cylinder head is lifted to the upper end of the upper chamber 412, and then the cold air flow from the lower chamber 413 into the upper chamber 412 is used to achieve rapid air cooling of the generator cylinder head.

[0076] The guide slots 414 are formed on the left and right sides of the heat preservation box 411 and are connected to the upper cavity 412 , so that the telescopic rod 32 can support the flipping set block 33 to enter the heat preservation box 411 and adjust its height.

[0077] The heat dissipation shutter 415 is located at the upper end of the upper chamber 412. The heat dissipation shutter 415 is closed during heating and heat preservation. When heat dissipation and cooling are required, the heat insulation plate 417 and the heat dissipation shutter 415 are opened at the same time.

[0078] The heat conductor 416 is located at the front side of the lower end of the upper cavity 412. A heater is provided in the insulation box 411 for transferring high-temperature heat to the heat conductor 416. The heater can be used to heat the heat conductor 416, and the high-temperature heat is transferred to the generator cylinder head located in the lower end of the upper cavity 412 through the heat conductor 416.

[0079] The heat insulation plate 417 is slidably installed in the middle of the insulation box 411, and the heat insulation plate 417 is located between the heat dissipation louver 415 and the heat conductor 416. The heat insulation plate 417 is used to dynamically divide the upper cavity 412 in the heating and cooling states to reduce heat loss during the heating and insulation periods.

[0080] The heat preservation assembly 42 further includes an artificial light source 421, a displacement slider 422, and a Y-shaped lifting frame 423:

[0081] The artificial light source 421 is fixedly mounted on the extended right-angle frame 13. The artificial light source 421 uses a powerful lighting lamp with a power of not less than 1500W and is equipped with a cooling protection structure to ensure stable lighting operation for 7h-14h, thereby performing stable heat preservation operation.

[0082] The displacement slider 422 is slidably installed on the extended right-angle frame 13 in the forward and backward directions, and the Y-shaped lifting frame 423 is slidably installed in the displacement slider 422, and the Y-shaped lifting frame 423 is rotatably installed with the square Fresnel lens 424 through the damping bearing. It should be noted that the extended right-angle frame 13 is provided with a first telescope for driving the displacement slider 422, and the displacement slider 422 is provided with a second telescope for driving the Y-shaped lifting frame 423. The square Fresnel lens 424 can be adjusted in the forward and backward directions on the Y-shaped lifting frame 423 so that the light source can illuminate the generator cylinder head hole through the square Fresnel lens 424 and then through the visual window 418.

[0083] The lifting slider 31 is vertically slidably installed in the gantry 11 , the telescopic rod 32 is horizontally slidably installed in the lifting slider 31 , and the flip set block 33 is rotatably installed on the telescopic rod 32 .

[0084] The temperature control assembly 41 is disposed on the load-bearing transverse plate 12 , and the heat insulation assembly 42 is disposed on the extending right-angle frame 13 .

[0085] A visual window 418 enclosed by flat glass and corresponding to the square Fresnel lens 424 is provided on the rear side of the insulation box 411. The flat glass greatly reduces the refraction of light, so that the light beam focused by the square Fresnel lens 424 can be accurately irradiated on the hole position of the generator cylinder head.

[0086] The square Fresnel lens 424 measures 155mm by 155mm. It hollows out the interior of the lens's curved surface, retaining only the portion that refracts. This portion then "collapses" onto a flat surface to receive light. This structure not only saves material but also improves focusing. Each groove in the square Fresnel lens 424 functions as an independent lens, resulting in a greater focusing capability than a typical convex lens.

[0087] It should be noted that the specific models and specifications of the boring and milling machine 2, the heat conductor 416, the artificial light source 421 and the square Fresnel lens 424 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0088] The present invention can be explained through the following operation mode:

[0089] Insert the left and right ends of the generator cylinder cover into the sleeve cavities 351 of the two flip sleeve blocks 33 respectively;

[0090] The driving components 34 in the two sets of limit adjustment mechanisms 3 are controlled to operate, wherein the driving slider 341 moves horizontally, and the steering lever 342 is pulled by the traction link 343 to deflect. The traction effect of the first traction long hole 344 and the first traction bolt 345 causes the telescopic rod 32 to move toward each other along the lifting slider 31. When the two flip set blocks 33 move toward each other, the two ends of the generator cylinder cover exert pressure on the T-shaped elastic resistance member 353 that contacts it, causing the supercharged wedge head 354 to shrink into the storage chamber 352, and exerting pressure on one end of the wedge head traction rocker 355. The wedge head pulls the rocker arm 355 to deflect, and its other end drives the supercharging plug 356 to move through the second traction long hole 357 and the second traction bolt 358 to clamp and fix the generator cylinder head. At the same time, the supercharging wedge head 354 drives the synchronous rack 3591 to move, and the synchronous rack 3591 rotates through the driven gear 3593. The damping shaft 3592 drives the limiting ratchet 3594 to rotate. During this process, the elastic pin 3595 movably contacts the limiting ratchet 3594 to prevent the T-shaped elastic contact member 353 from resetting.

[0091] Control the lifting slide 31 to move vertically to place the generator cylinder head in the heat preservation box 411, and control the turning set block 33 to turn 90 degrees so that the boring and milling hole position of the generator cylinder head corresponds to the heat conducting member 416, so that the temperature of the boring and milling hole position reaches 180°C;

[0092] After heating is completed, the artificial light source 421 is controlled to turn on, and the displacement slider 422 is controlled to move and the Y-shaped lifting frame 423 is controlled to rise and fall vertically, so that the square Fresnel lens 424 focuses on the boring and milling holes of the generator cylinder head, so that the temperature of the boring and milling holes of the generator cylinder head is maintained at 165°C-190°C for 8h-9.5h;

[0093] After the insulation is completed, the lifting slider 31 is controlled to lift the generator cylinder head to the upper end position of the upper chamber 412, and the lower chamber 413, the heat insulation plate 417 and the heat dissipation shutters 415 are opened to dissipate heat from the generator cylinder head until the temperature of the generator cylinder head drops to room temperature, and the temperature is further determined to be 23°C-30°C;

[0094] Control the lifting slider 31 to lift vertically, so that the generator cylinder head that has undergone solution aging treatment moves to the outside of the insulation box 411;
