Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a precision flange end face processing device for compressors. Background Technology

[0002] Precision flanges for compressors are core structural components connecting critical parts of the compressor, typically made of high-strength metal. Their end faces, as the main load-bearing area of ​​the sealing surface, bear multiple functions, including transmitting pressure, sealing the medium, and resisting vibration and thermal deformation. During compressor operation, the flange end face needs to be tightly fitted with the sealing gasket or mating flange; therefore, the flange end face requires machining and grinding.

[0003] Currently, flange face turning typically requires multiple steps. Changing between different turning steps necessitates manual tool changing and re-clamping, making the process cumbersome and reducing efficiency. Furthermore, most existing machining equipment is designed for a single operation, making it difficult to simultaneously perform flange face turning and grinding on a single machine. Therefore, in actual production, equipment often needs to be changed if grinding is required. Utility Model Content

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] Please see Figure 1-9This utility model provides a precision flange end face machining device for compressors, including a worktable 1, a grinder 5, and a ring tool holder 7. A fixed chuck 2 for clamping the compressor flange is located at the center of the worktable 1. A support frame 3 is fixedly connected above the worktable 1, and a long fixed cylinder 4 with an open lower end is connected below the support frame 3. The grinder 5 is slidably mounted inside the lower end of the long fixed cylinder 4. A longitudinal adjustment component 6 for driving the grinder 5 to rise and fall is connected to the upper end of the long fixed cylinder 4. The ring tool holder 7 is rotatably connected via bearings. On the outside of the long fixed cylinder 4, multiple sets of adjustable tool units 8 are evenly arranged on the inner circumference of the annular tool holder 7. Each set of adjustable tool units 8 includes a longitudinal guide rail 80 and a C-shaped tool frame 81 slidably arranged on it. The longitudinal guide rail 80 is fixed on the inner side of the annular tool holder 7. A manual adjustment component for driving the C-shaped tool frame 81 to rise and fall is connected above the C-shaped tool frame 81. A lathe tool 9 is detachably connected inside the C-shaped tool frame 81. A tool changing component 10 for driving the annular tool holder 7 to rotate is connected to one side of the annular tool holder 7.

[0031] In this invention, the operator first installs various turning tools 9 required for different turning processes on the flange end face inside the C-shaped tool holders 81. Next, a fixed chuck 2 is used to clamp and fix the flange to ensure its stability during machining. Then, the turning operation is initiated, and the fixed chuck 2 drives the flange to rotate at high speed, allowing the flange surface to effectively contact the turning tools 9, thus achieving the turning process. During turning, if it is necessary to switch to the next turning process, the operator can drive the annular tool holder 7 to rotate via the tool changer 10, quickly and accurately rotating the required turning tool 9 to the turning position. Then, the operator manually adjusts the descent height of the group of turning tools 9 using the manual adjustment mechanism, controlling the C-shaped tool holder 81 to descend to the required height, and then continues the turning operation. Finally, after the turning operation is completed, if it is necessary to grind the flange end face, simply raise the turning tool 9 inside the annular tool holder 7, and then control the descent of the grinder 5 via the longitudinal adjustment mechanism 6, positioning its grinding head on the flange end face for grinding.

[0032] Furthermore, the support frame 3 includes a support plate 31 and four sets of longitudinal columns 32. The four sets of longitudinal columns 32 are fixed in pairs on the left and right sides of the lower surface of the support plate 31. A longitudinal sliding seat 33 is provided below the support plate 31. The left and right sides of the longitudinal sliding seat 33 are slidably connected to the corresponding longitudinal columns 32. A longitudinal driving member 34 for driving the longitudinal sliding seat 33 to rise and fall is fixedly connected to the support plate 31. A fixed base 35 is slidably connected below the longitudinal sliding seat 33. A driving member 36 for driving the fixed base 35 to slide laterally is connected to the longitudinal sliding seat 33. A connecting plate 41 is fixedly connected to the upper end of the long fixed cylinder 4. The connecting plate 41 is slidably disposed below the fixed base 35. A driving member 37 for driving the connecting plate 41 to slide is connected inside the fixed base 35.

[0033] Specifically, by providing the longitudinal drive component 34, the longitudinal sliding seat 33 can slide up and down among the four sets of longitudinal columns 32, thereby indirectly adjusting the vertical movement of the cutting tool 9. By providing the first drive component 36, the fixed base 35 can slide left and right below the longitudinal sliding seat 33, thereby indirectly adjusting the horizontal movement of the cutting tool 9. By providing the second drive component 37, the connecting plate 41 can slide back and forth below the fixed base 35, thereby indirectly adjusting the forward and backward movement of the cutting tool 9. This support frame 3 enables the cutting tool 9 to move in three directions, greatly improving the working efficiency and processing quality of the device.

[0034] Furthermore, the longitudinal sliding seat 33 includes two sets of transverse guide rails 331 distributed front and rear. Both ends of the two sets of transverse guide rails 331 are fixedly provided with side seats 332. Two sets of guide blocks 333 are fixedly connected to the side of the side seat 332 away from the transverse guide rails 331. The guide blocks 333 are slidably connected to the longitudinal columns 32 at the corresponding positions. The longitudinal driving component 34 adopts a hydraulic cylinder. The upper surface of the two sets of transverse guide rails 331 is fixedly provided with a fixing plate 341. The telescopic end of the hydraulic cylinder passes through the support plate 31 and is fixedly connected to the fixing plate 341.

[0035] Specifically, by controlling the extension and retraction of the hydraulic cylinder piston rod, the longitudinal sliding seat 33 can be adjusted up and down among the four sets of longitudinal columns 32. During the downward sliding of the longitudinal sliding seat 33, the side seat 332 drives the guide block 333 to slide inside the corresponding longitudinal column 32. The longitudinal column 32 guides and limits the side seat 332, ensuring that the longitudinal sliding seat 33 slides up and down along a predetermined path.

[0036] Furthermore, a motor mounting housing 334 is fixedly connected to the middle position of one of the side seats 332 away from the transverse guide rail 331. The driving component 36 includes a lead screw 361 and a motor 362 fixedly connected inside the motor mounting housing 334. The lead screw 361 is rotatably connected between the two sets of side seats 332. One end of the lead screw 361 passes through one of the side seats 332 and is fixedly connected to the output shaft of the motor 362. A nut seat 363 is fixedly connected to the center position of the upper surface of the fixed base 35. The nut seat 363 is threaded on the outside of the lead screw 361. Slider blocks 351 are fixedly connected to both the front and rear sides of the upper surface of the fixed base 35. The two sets of sliders 351 are slidably connected inside the two sets of transverse guide rails 331 respectively.

[0037] Specifically, when the fixed base 35 moves, it causes the slider 351 to slide within the corresponding transverse guide rail 331. The transverse guide rail 331 guides and limits the slider 351, ensuring that the slider 351 can only move along the transverse guide rail 331, thereby indirectly limiting the movement trajectory of the nut seat 363. When it is necessary to control the fixed base 35 to slide left and right below the longitudinal sliding seat 33, the motor 362 needs to be operated. The output shaft of the motor 362 drives the lead screw 361 to rotate. With the cooperation of the slider 351 and the transverse guide rail 331, the nut seat 363 will move linearly along the lead screw 361, thereby causing the fixed base 35 to slide synchronously. When it is necessary to change the direction of movement of the fixed base 35, it is only necessary to change the direction of rotation of the motor 362.

[0038] Furthermore, a motor mounting housing 352 is fixedly connected to the rear side of the fixed base 35. The driving component 37 includes a lead screw 371 and a motor 372 fixedly connected inside the motor mounting housing 352. The lead screw 371 is rotatably connected inside the fixed base 35. The rear end of the lead screw 371 passes through the rear side wall of the fixed base 35 and is fixedly connected to the output shaft of the motor 372. A nut seat 373 is fixedly connected to the upper surface of the connecting plate 41. The nut seat 373 is threaded on the outside of the lead screw 371 and slidably connected inside the fixed base 35.

[0039] Specifically, when it is necessary to control the connecting plate 41 to slide back and forth under the fixed base 35, the motor 372 needs to be operated. The output shaft of the motor 372 drives the lead screw 371 to rotate. At this time, the nut seat 373 will move back and forth along the internal space of the fixed base 35, thereby driving the connecting plate 41 to move back and forth. When it is necessary to change the direction of movement of the connecting plate 41, it is only necessary to change the direction of rotation of the motor 372.

[0040] Furthermore, the longitudinal adjustment component 6 includes an electric push rod 61, which is fixedly connected to the upper end of the inside of the long fixed cylinder 4. The telescopic end of the electric push rod 61 is fixedly connected to a fixed frame 62, and the body of the grinder 5 is fixedly connected to the inside of the fixed frame 62. The fixed frame 62 is slidably connected to the inside of the long fixed cylinder 4.

[0041] Specifically, during the turning process, the telescopic rod of the electric push rod 61 is in the retracted state, at which point the grinder 5 is located inside the long fixed cylinder 4. When grinding of the flange end face is required, the telescopic rod of the electric push rod 61 is extended, thereby pushing the fixed frame 62 and the grinder 5 to descend. As the telescopic rod extends, the fixed frame 62 and the grinder 5 gradually lower until the grinding head of the grinder 5 extends out from the lower opening of the long fixed cylinder 4.

[0042] Furthermore, the annular tool holder 7 includes an upper disc 71 and a lower disc 73. The upper disc 71 is rotatably sleeved on the outside of the long fixed cylinder 4 via bearings. Multiple sets of vertical plates 72 are uniformly fixed to the lower surface of the upper disc 71. The lower disc 73 is fixedly connected to the lower end of the multiple sets of vertical plates 72 and is rotatably sleeved on the outside of the long fixed cylinder 4 via bearings. A longitudinal guide rail 80 is fixedly connected between the upper disc 71 and the lower disc 73. Multiple sets of threaded holes 711 are uniformly opened through the surface of the upper disc 71. The surface of the lower disc 73... Multiple sets of cutting holes 731 are evenly opened in the circumference. The positions of the threaded hole 711, the cutting hole 731 and the longitudinal guide rail 80 are one-to-one. The upper end of each C-shaped tool frame 81 is fixedly connected to a top plate 82. The manual adjustment component includes a threaded adjustment rod 83 threadedly connected inside the threaded hole 711. The lower end of the threaded adjustment rod 83 is rotatably connected to the upper surface of the top plate 82. A slide bar 84 is fixedly connected to the side of the C-shaped tool frame 81 near the longitudinal guide rail 80. The slide bar 84 is slidably connected inside the longitudinal guide rail 80 at the corresponding position.

[0043] Specifically, when a turning operation needs to be changed, the operator can use the threaded adjusting rod 83 to move the cutting tool 9 from its original turning position to inside the annular tool holder 7 (i.e., above the lower tool hole 731). Then, the tool changer 10 drives the annular tool holder 7 to rotate, moving the cutting tool 9 for the next operation to the turning position. Then, the threaded adjusting rod 83 is used again to move the cutting tool 9 from the turning position to below the annular tool holder 7 (i.e., below the lower tool hole 731), allowing for turning operations. The adjustment method of the threaded adjusting rod 83 is very convenient; the operator only needs to manually rotate the threaded adjusting rod 83. Under the coordinated action of the slide bar 84 and the longitudinal guide rail 80, the top plate 82 and the C-shaped tool frame 81 will smoothly descend along the longitudinal guide rail 80, ultimately driving the cutting tool 9 through the lower tool hole 731 and down to the predetermined working height. The sliding of the slide bar 84 inside the longitudinal guide rail 80 is guided and positioned by the longitudinal guide rail 80, ensuring smooth up-and-down movement of the C-shaped tool frame 81.

[0044] Furthermore, side holes 811 are provided through the center of both sides of the C-shaped tool frame 81, and threaded holes 812 are provided through the center of both sides of the C-shaped tool frame 81, above and below the side holes 811. Positioning ribs 813 are fixedly connected to the upper and lower ends of both sides of the C-shaped tool frame 81. Both sides of the lathe tool 9 have a set of limiting holes 91 corresponding to the side holes 811, two sets of fixing holes 92 corresponding to the threaded holes 812, and two sets of positioning grooves 93 that cooperate with the positioning ribs 813. The two sets of positioning grooves 93 are located on the side of the two sets of fixing holes 92 away from the limiting holes 91. The side holes 811 are connected to a device for limiting the C-shaped tool frame 81. An elastic limiting member 85 is positioned opposite to the cutting tool 9. The elastic limiting member 85 includes a fixed shell 851 and a limiting pin 852. The fixed shell 851 is fixedly connected to the outside of the side hole 811. The side of the fixed shell 851 closest to the side hole 811 is open. The limiting pin 852 is slidably connected to the inside of the fixed shell 851. A spring 853 is fixedly connected between the limiting pin 852 and the fixed shell 851. Under the elastic action of the spring 853, the limiting pin 852 abuts against the inside of the corresponding limiting hole 91. A fixing bolt 86 is threadedly connected to the inside of the threaded hole 812. The end of the fixing bolt 86 passes through the threaded hole 812 and abuts against the inside of the fixing hole 92.

[0045] Specifically, when installing the cutting tool 9, firstly, the positioning grooves 93 on both sides of the cutting tool 9 are aligned with the positioning ribs 813 inside the C-shaped tool frame 81 to ensure accurate positioning of the cutting tool 9. As the cutting tool 9 is further inserted, the limiting pin 852 in the elastic limiting member 85 automatically moves and is fixed in the limiting hole 91 of the cutting tool 9 under the action of the spring 853, thereby achieving initial stable positioning of the cutting tool 9. During this process, the limiting pin 852 will play a buffering and locking role under the action of the spring 853, preventing the cutting tool 9 from shifting during installation. After completing the initial positioning, the cutting tool 9 is further fixed using the fixing bolt 86. The end of the fixing bolt 86 passes through the threaded hole 812, ensuring that the fixing bolt 86 can abut against the fixing hole 92 of the cutting tool 9, thereby achieving secondary fixing of the cutting tool 9. This double fixing structure effectively ensures the stability of the cutting tool 9 within the C-shaped tool frame 81.

[0046] Furthermore, an external gear ring 101 is fixedly sleeved on the outer side of the upper disc 71, and a short fixed cylinder 102 is fixedly connected to the rear side of the lower surface of the connecting plate 41. A motor 103 is fixedly connected inside the short fixed cylinder 102, and a gear 104 is fixedly sleeved on the output shaft of the motor 103. The gear 104 meshes with one side of the external gear ring 101.

[0047] Specifically, when it is necessary to drive the ring tool holder 7 to rotate, the control motor 3 103 is operated. The output shaft of the motor 3 103 drives the gear 104 to rotate, and the gear 104 drives the external gear ring 101 meshing with it to rotate, thereby driving the upper disc 71, the vertical plate 72 and the lower disc 73 to rotate synchronously.

[0048] It should be noted that all electrical devices mentioned above are controlled via electrical connection to the control terminal.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
