Description

Technical Field

[0001] The present invention relates to the technical field of generator cylinder head processing, and particularly to a boring and milling device for processing generator cylinder heads. Background Art

[0002] Generators are common large-scale machines in modern society. The quality of a generator is related to multiple factors. The quality of the generator cylinder head seriously affects the quality and performance of the generator. Currently, aluminum alloy is a common material for generator cylinder heads, and the opening structure in the aluminum alloy generator cylinder head has a crucial impact on the operation of the generator. Therefore, under the existing conditions, the boring and milling processing technology is mostly used to process the opening structure of the generator cylinder head.

[0003] Existing boring and milling processing equipment, such as a boring and milling processing equipment for numerically controlling the processing of generator cylinder heads disclosed in the publication number CN213730574U, believes that there is no heat dissipation structure during use. During the processing process, the processing disk is prone to generate high temperature, reducing its service life. Therefore, it is proposed to set up a water storage tank, a filter screen and a water outlet to achieve flushing the processing position at any time, and purify and recycle the processing fluid through the filtration of the V-shaped filter screen. However, because the aluminum alloy generator cylinder head is different from other materials, the following problems exist: First of all, the melting point of aluminum alloy is relatively low. The high-speed cutting operations of the boring tool and the milling tool cause the generator cylinder head to withstand great external force impacts and high-temperature pressures. Under their action, the structural hardness and strength of the generator cylinder head will both decrease. In particular, the hole structures directly in contact with the boring tool and the milling tool may even deform and crack. Secondly, although aluminum alloy itself has certain corrosion resistance, during the boring and milling processing, because auxiliary solutions such as coolant are used, and they are rich in various components that can easily cause corrosion of the aluminum alloy generator cylinder head. If the generator cylinder head is not subjected to corrosion resistance treatment, it will cause serious corrosion deformation of the hole structure.

[0004] Although certain structural strengthening measures are also taken for the aluminum alloy generator cylinder head under the existing conditions, such as adding reinforcing ribs to achieve stress relief, it is still impossible to protect the structure of the generator cylinder head against the boring tool and the milling tool under high temperature and high pressure. Even if solution treatment is used, it is to realize the overall temperature rise and fall operation of the generator cylinder head, but there is an easy problem of continuous heat preservation difficulty, and it is impossible to achieve continuous heat preservation of the hole position to be bored and milled on the generator cylinder head. Therefore, it is difficult to ensure the structural strength of the hole position to be bored and milled on the generator cylinder head through solution aging treatment. Summary of the Invention

[0005] 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 the generator cylinder head, and to propose a boring and milling device for processing generator cylinder heads.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A boring and milling device for processing a generator cylinder head, comprising a machine body composed of a gantry, a load-bearing cross plate and an extended right-angle frame, The machine body is provided with: A boring and milling integrated machine, the boring and milling integrated machine includes a compressor, and the boring and milling integrated machine is arranged at the top of the gantry. The boring and milling integrated machine for lubricating and cooling through the compressor is used for boring and milling the hole positions of the generator cylinder head from top to bottom; A limit adjustment mechanism, and the number of the limit adjustment mechanisms is two groups. The limit adjustment mechanism includes a lifting slider, a telescopic rod and a flipping sleeve block. The two groups of limit adjustment mechanisms horizontally sleeve the left and right ends of the generator cylinder head through the flipping sleeve block, and adjust the generator cylinder head vertically, horizontally and front-back by the lifting slider and the telescopic rod; The machine body is provided with: A strengthening mechanism, the strengthening mechanism includes a temperature control component and a heat preservation component for performing solution aging treatment on the generator cylinder head. The heat preservation component includes a square Fresnel lens, and the strengthening mechanism performs end-point temperature control on the hole positions of the generator cylinder head through the square Fresnel lens.

[0007] Preferably, the load-bearing cross plate is horizontally welded to the middle position of the gantry, and the extended right-angle frame is welded to the rear position of the gantry.

[0008] Preferably, the output end of the compressor is movably connected with a high-pressure air jet located on the gantry for spraying lubricant.

[0009] Preferably, the lifting slider is vertically slidably installed in the gantry, the telescopic rod is horizontally slidably installed in the lifting slider, and the flipping sleeve block is rotatably installed on the telescopic rod.

[0010] Preferably, a driving component for driving the telescopic rod to move horizontally is arranged on the lifting slider.

[0011] Preferably, a locking component for clamping the left and right ends of the generator cylinder head in opposite directions is arranged on the flipping sleeve block.

[0012] Preferably, the temperature control component is arranged on the load-bearing cross plate, and the heat preservation component is arranged on the extended right-angle frame.

[0013] Preferably, the temperature control component includes a heat preservation box fixedly installed on the load-bearing cross plate. The heat preservation box is used for heating the temperature of the generator cylinder head to 155°C - 193°C and cooling the temperature of the generator cylinder head to 17°C - 32°C.

[0014] Preferably, a viewing window closed by flat glass and corresponding to a square Fresnel lens is provided on the rear side of the thermal insulation box.

[0015] Preferably, the length and width of the square Fresnel lens are 155mm*155mm.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention utilizes a gantry, a load-bearing cross plate and an extended right-angle frame to form a machine body, and utilizes the gantry 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 that can lubricate and spray the boring cutter and the milling cutter are provided, 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.

[0017] 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 component 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 component, thereby ensuring that the generator cylinder cover can be displaced left and right, lifted vertically, and flipped forward and backward according to the needs of solution aging treatment and boring and milling processing.

[0018] 3. The present invention opens a sleeve cavity in the flip sleeve block, and arranges a T-shaped elastic abutment member in the sleeve cavity to abut against the end of the generator cylinder head. The T-shaped elastic abutment member 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 limit the limit ratchet in one direction, so that the positioning tool can prevent the boost plug-in in the clamping state from resetting and ensure the stability during the process of clamping the generator cylinder head and entering and exiting the insulation box.

[0019] 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 conductive member, and can be cooled by using a lower cavity and heat dissipation shutters. 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. The hole structure of the generator cylinder head after heating, insulation and cooling can effectively improve the structural strength, hardness, fatigue resistance and corrosion resistance, and avoid deformation and rupture of the hole structure of the generator cylinder head caused by high-temperature pressurization of the boring cutter and the milling cutter.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-10 , a boring and milling device for machining a generator cylinder head, including a machine body 1 composed of a gantry 11, a load-bearing horizontal plate 12 and an extended right-angle frame 13. The load-bearing horizontal plate 12 is horizontally welded at the middle position of the gantry 11, and the extended right-angle frame 13 is welded at the rear position of the gantry 11.

[0024] The machine body 1 is provided with a boring and milling integrated machine 2 and a limit adjustment mechanism 3 through the gantry 11: The boring and milling integrated machine 2 includes a compressor 23, and the boring and milling integrated machine 2 is arranged at the top position of the gantry 11. The output end of the compressor 23 is movably connected with a high-pressure air jet 24 located on the gantry 11 for spraying lubricant. The boring and milling integrated machine 2 for lubricating and cooling by the compressor 23 is used for boring and milling the hole positions of the generator cylinder head from top to bottom. The compressor 23 and the high-pressure air jet 24 are located at the middle position of the gantry 11. It should be noted that by compressing air and lubricant by the compressor 23, the high-pressure air jet 24 that can be vertically lifted and horizontally rotated is used to cool and lubricate the boring tool group 21 and the milling tool group 22, so as to avoid the high-temperature conduction pressure damage to the hole positions of the generator cylinder head caused by the high-speed rotating boring tool group 21 and milling tool group 22.

[0025] The boring and milling integrated machine 2 further includes a boring tool group 21 and a milling tool group 22. The boring tool group 21 and the milling tool group 22 are symmetrically arranged about the vertical center line of the gantry 11. The boring tool group 21 and the milling tool group 22 are mature technical means commonly used in the technical field to which this technology belongs, so no further description will be given.

[0026] There are two sets of limit adjustment mechanisms 3. The limit adjustment mechanism 3 includes a lifting slider 31, a telescopic rod 32 and a flipping sleeve block 33. The two sets of limit adjustment mechanisms 3 are horizontally sleeved on the left and right ends of the generator cylinder head through the flipping sleeve block 33, and the generator cylinder head is vertically lifted, horizontally displaced and flipped forward and backward through the lifting slider 31 and the telescopic rod 32. It should be noted that a driving hydraulic cylinder for driving the lifting slider 31 to vertically lift is provided on the gantry 11. Under the control of the servo controller used in cooperation, the lifting slider 31 drives the generator cylinder head to adjust the height position through the telescopic rod 32 and the flipping sleeve block 33. Similarly, a driving motor for driving the flipping sleeve block 33 to flip in the front and back directions is provided in the telescopic rod 32, 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 hole position of the generator cylinder head is facing up, it corresponds to the boring and milling integrated machine 2, when it is facing backward, it corresponds to the heat preservation component 42 and the temperature control component 41, and when it is facing down, it corresponds to the lower cavity 413 for heat dissipation and cooling.

[0027] A driving component 34 for driving the telescopic rod 32 to horizontally displace is provided on the lifting slider 31. The driving component 34 includes a driving slider 341 and a steering lever 342: The driving slider 341 is slidably installed on the lifting slider 31, and a driving cylinder for pulling and driving the driving slider 341 to horizontally move is provided in the lifting slider 31. By controlling the horizontal movement of the driving slider 341, the steering lever 342 can be deflected left and right.

[0028] The steering lever 342 is rotatably installed on the lifting slider 31, and a traction connecting rod 343 is pin-connected between one end of the steering lever 342 and the driving slider 341. A first traction long hole 344 is opened in the other end of the steering lever 342. A first traction bolt 345 that is integrally connected to the telescopic rod 32 and slidably sleeved in the first traction long hole 344 is provided. Under the traction of the steering lever 342, the telescopic rod 32 moves along the left and right directions of the lifting slider 31, so as to preliminarily sleeve the generator cylinder head by using the flipping sleeve block 33.

[0029] A locking component 35 for oppositely clamping the left and right ends of the generator cylinder head is provided on the flipping sleeve block 33. The locking component 35 includes a sleeve cavity 351, a storage cavity 352, a T-shaped elastic abutting member 353, a pressurizing wedge head 354, a wedge head traction swing rod 355, a pressurizing plug-in 356, and a positioning tooling 359: The sleeve cavity 351 is opened at the outer side position of the flipping sleeve block 33 for preliminarily sleeving the left and right ends of the generator cylinder head.

[0030] The storage cavity 352 is opened at the inner side position of the flipping sleeve block 33, and the storage cavity 352 is communicated with the sleeve cavity 351.

[0031] The T-shaped elastic contact member 353 is sleeved in the sleeve cavity 351 and the storage cavity 352, and the T-shaped elastic contact member 353 is used to abut against the end of the generator cylinder head sleeved in the sleeve cavity 351. In the initial state, the T-shaped elastic contact member 353 maintains a tendency to extend outward from the storage cavity 352. When the two flipping sleeve blocks 33 are moved toward each other, the generator cylinder head can be used to press the T-shaped elastic contact member 353, causing the T-shaped elastic contact member 353 to move toward the storage cavity 352 side.

[0032] The boosting wedge head 354 is fixedly connected to one end of the T-shaped elastic contact member 353 located in the storage cavity 352. The boosting wedge head 354 is of a hollow structure to facilitate the internal placement of the synchronous rack 3591.

[0033] The wedge head traction swing rod 355 is rotatably installed on the flipping sleeve block 33, and one end of the wedge head traction swing rod 355 is movably abutted against the boosting wedge head 354. A second traction long hole 357 is formed in the other end of the wedge head traction swing rod 355. The wedge head traction swing rod 355 deflects under the pressure of the boosting wedge head 354, and then drives the symmetrically arranged boosting plugs 356 to move toward each other, thereby clamping and fixing the generator cylinder head.

[0034] The boosting plug 356 is slidably installed on the flipping sleeve block 33, and a second traction bolt 358 integrally connected to the boosting plug 356 is slidably sleeved in the second traction long hole 357.

[0035] The positioning tooling 359 is arranged in the storage cavity 352 through the boosting wedge head 354, and the positioning tooling 359 fixes the boosting plug 356 that abuts against the generator cylinder head through the boosting wedge head 354. The positioning tooling 359 includes a synchronous rack 3591, a damping rotating shaft 3592, a driven gear 3593, a limiting ratchet 3594, and an elastic pin 3595: The synchronous rack 3591 is integrally connected to the boosting wedge head 354. The damping rotating shaft 3592 is rotatably installed in the storage cavity 352. The driven gear 3593 is key-connected to the damping rotating shaft 3592, and the driven gear 3593 is meshed with the synchronous rack 3591. The limiting ratchet 3594 is key-connected to the damping rotating shaft 3592. It should be noted that during the process of the T-shaped elastic contact member 353 driving the synchronous rack 3591 to move through the boosting wedge head 354, the damping rotating shaft 3592 and the limiting ratchet 3594 rotate synchronously due to the meshing transmission between the synchronous rack 3591 and the driven gear 3593.

[0036] The elastic bolt 3595 is rotatably mounted on the pressurizing wedge head 354 through a torsion spring, and the elastic bolt 3595 is in movable contact with the limiting ratchet 3594. Under the elastic support of the torsion spring, the elastic bolt 3595 always maintains a tendency to move forward and downward, so as to make movable contact with each tooth of the limiting ratchet 3594, so as to perform one-way limiting on the rotating limiting ratchet 3594, avoid the automatic reset of the T-shaped elastic contact member 353 due to elasticity, and ensure the stability of driving the wedge head to pull the swing rod 355 through the pressurizing wedge head 354 to clamp the generator cylinder head.

[0037] It should be noted that when it is necessary to release the limit on the generator cylinder head, by squeezing one end of the elastic bolt 3595 away from the limiting ratchet 3594 on the flipping sleeve block 33, the elastic bolt 3595 stops limiting the limiting ratchet 3594. At this time, the T-shaped elastic contact member 353 can be reset by its own elasticity.

[0038] The machine body 1 is provided with a strengthening mechanism 4 through the load-bearing cross plate 12 and the extending right-angle frame 13: The strengthening 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 strengthening mechanism 4 performs end-point temperature control on the hole positions of the generator cylinder head through the square Fresnel lens 424.

[0039] The temperature control component 41 includes a heat preservation box 411 fixedly installed on the load-bearing cross plate 12. The heat preservation box 411 is used to heat the temperature of the generator cylinder head to 155°C - 193°C and cool the temperature of the generator cylinder head to 17°C - 32°C. The temperature control component 41 also includes an upper cavity 412, a lower cavity 413, a guiding notch 414, a heat dissipation louver 415, a heat conducting member 416, and a heat insulation plate 417: The heat preservation box 411 is fixedly installed on the load-bearing cross plate 12. The generator cylinder head is placed inside the heat preservation box 411 to facilitate heating, heat preservation, and cooling treatment. In the relatively enclosed heat preservation box 411, targeted heat preservation treatment is performed on the hole positions of the generator cylinder head to improve the stability of the heat preservation state of the generator cylinder head and help reduce the diffusion and loss of high-temperature heat.

[0040] It should be noted that after the generator cylinder head is symmetrically clamped and fixed by the locking component 35, the state of the generator cylinder head is adjusted by using the limit adjustment mechanism 3 according to the needs of heating, heat preservation, cooling, and boring and milling processing, so that the generator cylinder head can perform height lifting, front-back flipping, and left-right translation in the heat preservation box 411.

[0041] The upper cavity 412 is opened at the upper end position of the heat preservation box 411, and the rear side of the lower end of the upper cavity 412 is communicated with the viewing window 418.

[0042] The lower cavity 413 is opened at the lower end of the incubator 411. It should be noted that a ventilation opening connecting the upper cavity 412 and the lower cavity 413 is opened in the middle of the incubator 411, and a radiator is provided in the lower cavity 413. When the generator cylinder head needs to be cooled, the generator cylinder head is lifted to the upper end position of the upper cavity 412, and then the cold air flow entering the upper cavity 412 from the lower cavity 413 is used to quickly air-cool the generator cylinder head.

[0043] The guiding slots 414 are opened at the left and right positions of the incubator 411, and the guiding slots 414 are communicated with the upper cavity 412, so as to facilitate the telescopic rod 32 to support the flipping and sleeving block 33 to enter the incubator 411 and adjust the height.

[0044] The heat dissipation louvers 415 are located at the upper end of the upper cavity 412. The heat dissipation louvers 415 are closed during heating and heat preservation. When heat dissipation and cooling are required, the heat insulation board 417 and the heat dissipation louvers 415 are opened simultaneously.

[0045] The heat conducting member 416 is located at the front side of the lower end of the upper cavity 412. A heater for transferring high-temperature heat to the heat conducting member 416 is provided in the incubator 411. The heat conducting member 416 can be heated by the heater, and the high-temperature heat is conducted to the generator cylinder head located inside the lower end of the upper cavity 412 through the heat conducting member 416.

[0046] The heat insulation board 417 is slidably installed in the middle of the incubator 411, and the heat insulation board 417 is located between the heat dissipation louvers 415 and the heat conducting member 416. The heat insulation board 417 is used to dynamically divide the upper cavity 412 in the heating and cooling states, and reduce heat loss during the heating and heat preservation periods.

[0047] The heat preservation assembly 42 further includes an artificial light source 421, a displacement slider 422, and a Y-shaped lifting frame 423: The artificial light source 421 is fixedly installed 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 and protection structure to ensure stable lighting operation for a long time of 7h - 14h, so as to perform stable heat preservation operation.

[0048] The displacement slider 422 is slidably installed on the extended right-angle frame 13 in the front-rear direction. 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 a square Fresnel lens 424 through a damping bearing. It should be noted that a first telescopic device for driving the displacement slider 422 is provided on the extended right-angle frame 13, and a second telescopic device for driving the Y-shaped lifting frame 423 is provided on the displacement slider 422. The square Fresnel lens 424 can be adjusted in the front-rear direction on the Y-shaped lifting frame 423, so as to facilitate the light source to irradiate the hole position of the generator cylinder head through the square Fresnel lens 424 and then through the viewing window 418.

[0049] The lifting slider 31 is installed in the gantry 11 in a vertical sliding manner, the telescopic rod 32 is installed in the lifting slider 31 in a horizontal sliding manner, and the flip set block 33 is rotatably installed on the telescopic rod 32 .

[0050] The temperature control component 41 is disposed on the load-bearing transverse plate 12 , and the heat preservation component 42 is disposed on the extending right-angle frame 13 .

[0051] A visual window 418 closed by flat glass and corresponding to the square Fresnel lens 424 is provided on the rear side of the thermal 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 of the generator cylinder head.

[0052] The square Fresnel lens 424 has a length and width of 155mm*155mm. It hollows out the inside of the lens surface, leaving only the part that refracts, and then "collapses" onto a plane to receive light. This structure not only saves materials, but also helps to improve the focusing effect. Each groove of the square Fresnel lens 424 can become an independent lens, so its focusing ability exceeds that of an ordinary convex lens.

[0053] 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, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0054] The present invention can be explained by the following operation mode: The left and right ends of the generator cylinder cover are respectively mounted in the mounting cavities 351 of the two flip mounting blocks 33; 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 pulling connecting rod 343 to deflect. The pulling action of the first pulling long hole 344 and the first pulling 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 apply pressure to the T-shaped elastic resistance member 353 that contacts with it, so that the supercharger wedge 354 shrinks into the storage chamber 352, and exerts pressure on one end of the wedge head pulling swing rod 355. The wedge head traction swing rod 355 is deflected, and the other end thereof drives the boost plug 356 to move through the second traction long hole 357 and the second traction bolt 358 to clamp and fix the generator cylinder cover. At the same time, the boost wedge head 354 drives the synchronous rack 3591 to move, and the synchronous rack 3591 rotates through the driven gear 3593, and the damping shaft 3592 drives the limit ratchet 3594 to rotate. In this process, the elastic pin 3595 movably contacts the limit ratchet 3594 to prevent the T-shaped elastic contact member 353 from resetting. Control the vertical movement of the lifting slider 31 to place the generator cylinder head in the heat preservation box 411. At the same time, control the flipping sleeve block 33 to flip 90° so that the boring and milling processing hole positions of the generator cylinder head correspond to the heat conducting part 416, and make the temperature of the boring and milling processing hole positions reach 180°C. After the heating is completed, control the artificial light source 421 to turn on, and control the displacement slider 422 to move and the Y-shaped lifting frame 423 to lift vertically, so that the square Fresnel lens 424 focuses on and irradiates the boring and milling processing hole positions of the generator cylinder head, and keeps the temperature of the boring and milling processing hole positions of the generator cylinder head at 165°C - 190°C for 8h - 9.5h. After the heat preservation is completed, control the lifting slider 31 to lift so that the generator cylinder head is lifted to the upper end position of the upper cavity 412. Open the lower cavity 413, the heat insulation plate 417 and the heat dissipation louvers 415 to dissipate heat from the generator cylinder head until the temperature of the generator cylinder head drops to the room temperature level, and further determine that the temperature is 23°C - 30°C.
