Description

Technical Field

[0001] The invention relates to the technical field of boring and milling processing, in particular to a horizontal double-sided boring and milling processing center. Background Art

[0002] Boring and milling (also known as boring) is an internal diameter cutting process that uses a tool to enlarge a hole or other circular contour. Its application range generally ranges from semi-roughing to finishing, and the tool used is usually a milling cutter.

[0003] Existing boring and milling devices also have the following defects: First, in the field of mechanical processing, the requirements for processing accuracy and efficiency of various large and complex parts are increasing. The traditional single-sided processing method is gradually unable to meet the needs of modern manufacturing, both in terms of processing efficiency and ensuring the overall accuracy of parts. In the field of aerospace, key parts such as engine casings have complex structures and large sizes, and require high-precision boring and milling on multiple surfaces. If traditional equipment is used, multiple clamping and positioning are required, which is not only inefficient, but the accumulated errors from multiple clamping will seriously affect the final accuracy of the parts.

[0004] Secondly, during the boring and milling process, the milling cutter will continuously feed and bore the workpiece. During the feeding process of the milling cutter, since the milling cutter will continuously resist the workpiece, the workpiece may be displaced due to insufficient clamping force of the fixture, which will eventually affect the normal boring and milling of the milling cutter. Third, before boring and milling, the workpiece needs to be positioned and installed. For rectangular workpieces, traditional positioning methods mostly use positioning rods for positioning, but the positioning rods themselves cannot be adjusted. When the size of the rectangular workpiece changes, the traditional positioning method cannot meet the current workpiece positioning requirements. Summary of the invention

[0018] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] refer to Figures 1 to 13 A horizontal double-sided boring and milling machining center shown in the figure comprises a machining table 1, on which a double-sided boring and milling assembly is arranged, and the double-sided boring and milling assembly comprises a supporting mechanism, a translation mechanism, a boring and milling mechanism and a clamping mechanism, wherein the supporting mechanism comprises a strip-shaped supporting table 2 and a mounting table 3, wherein the strip-shaped supporting table 2 is horizontally arranged on the machining table 1, and the mounting table 3 is horizontally arranged above the strip-shaped supporting table 2, and the translation mechanism comprises a No. 1 slide 4 and two No. 2 slides 5, wherein the No. 1 slide 4 is arranged on the mounting table 3, The two No. 2 slides 5 are symmetrically arranged at the two ends of the strip support platform 2, respectively. The boring and milling mechanism includes two groups of symmetrical milling cutters 6. Each No. 2 slide 5 is provided with a lifting seat 7. Each milling cutter 6 is connected to the corresponding lifting seat 7. The clamping mechanism includes a correction member 8 and two groups of clamping members 9. The correction member 8 is arranged on the strip support platform 2. The correction member 8 includes two groups of symmetrically distributed moving arms 10 and a lifting baffle 11. The lifting baffle 11 is arranged on the moving arm 10 (such as Fig.11 As shown in the figure), a lifting drive member 12 is provided between each movable arm 10 and the No. 1 slide 4, two groups of clamping members 9 are symmetrically arranged on the No. 1 slide 4, a support platform 13 is provided between the two groups of clamping members 9, and each group of clamping members 9 includes two symmetrically distributed movable clamping plates 14.

[0020] The device is used for double-sided boring and milling of rectangular workpieces. When double-sided boring and milling is performed, the workpiece to be bored and milled is placed on the support 13 (such as Fig. 9 As shown in the figure, when the workpiece is placed on the support 13, the workpiece will be between the four movable clamps 14, and then the two movable clamps 14 in each group of clamps 9 will move toward each other. During this process, the two ends of the workpiece will be deflected due to the resistance of the movable clamps 14, so as to align the workpiece. As the movable clamps 14 continue to move, the ends of the workpiece will eventually be clamped by the corresponding two movable clamps 14. When the workpiece is clamped, the workpiece will be in an aligned state. Since the distances between the two ends of the workpiece and the two milling cutters 6 may be different at this time, it is necessary to calibrate the distance between the workpiece and the milling cutter 6. The specific correction process is as follows: when the workpiece is aligned, the two movable clamps 14 will move in the opposite direction. At this time, the workpiece is in a free state. At the same time, the two groups of movable arms 10 in the correction member 8 will move toward each other. At this time, the two lifting baffles 11 will approach the two ends of the workpiece respectively. The two lifting baffles 11 will respectively contact the two ends of the workpiece, and finally the distance between the two ends of the workpiece and the two milling cutters 6 will be corrected to be consistent. After that, the two movable clamps 14 in each group of clamping members 9 will move toward each other again, and finally the workpiece will be clamped. At this time, the workpiece realizes the alignment of the position and the correction of the distance with the milling cutter 6; When the workpiece is clamped for the second time by the movable clamping plate 14, the two No. 2 slides 5 will translate toward each other, so that the lifting seat 7 arranged on the No. 2 slide 5 will drive the milling cutter 6 to move to the corresponding end of the workpiece. Thereafter, each lifting driving member 12 will drive the corresponding lifting baffle 11 to descend, so that the end of the workpiece is exposed in front of the milling cutter 6. Then, with the continuous feeding of the No. 2 slide 5, each milling cutter 6 will bore and mill the corresponding end of the workpiece. When it is necessary to bore and mill a single side of the workpiece, one of the No. 2 slides 5 will not move, and the other No. 2 slide 5 will continue to feed. Then, one of the milling cutters 6 will bore and mill a single end of the workpiece. During this process, only one lifting baffle 11 will descend, and the other lifting baffle 11 will continue to be in an ascending state. Then, when the milling cutter 6 is boring and milling, the end of the workpiece is blocked by the lifting baffle 11 in an ascending state, so as to overcome the feeding force of the milling cutter 6 and prevent the workpiece from being pushed by the milling cutter 6 during single-sided boring and milling.

[0021] In order to show the specific installation method of the lifting baffle 11, the following features are set: Each movable arm 10 includes a flat plate 15 and a vertical plate 16. The vertical plate 16 is vertically upward. The lower end of the vertical plate 16 is fixedly connected to the flat plate 15. The upper end of the vertical plate 16 is formed with a No. 1 support plate 17 parallel to the flat plate 15. Each lifting baffle 11 includes a No. 2 support plate 18, a strip baffle 19 and a connecting plate 20. The No. 2 support plate 18 is horizontally arranged on the side of the vertical plate 16, the strip baffle 19 is vertically arranged above the No. 2 support plate 18, and the connecting plate 20 vertically connects the strip baffle 19 and the No. 2 support plate 18. A plurality of vertically upward No. 1 limit rods 21 are formed on the top of the No. 2 support plate 18, and each No. 1 limit rod 21 passes through the No. 1 support plate 17.

[0022] Since the No. 1 limit rod 21 passes upward through the No. 1 support plate 17, when the movable arm 10 is displaced, the No. 1 support plate 17 on the vertical plate 16 will drive the entire lifting baffle 11 to displace through a plurality of No. 1 limit rods 21. When the two lifting baffles 11 approach each other, the strip baffles 19 in each lifting baffle 11 will conflict with the end of the workpiece, and finally the distance between the end of the workpiece and the milling cutter 6 is corrected by the relative displacement of the two strip baffles 19.

[0023] In order to show the specific structure of the lifting drive member 12, the following features are set: Each lifting drive member 12 includes a connecting block 22, a slide rod 23, a spring 24 and two special-shaped side plates 25. Each of the two second support plates 18 is formed with a vertical downward support block 26 on both sides, and each support block 26 is fixedly connected with a strip side plate 27. The two special-shaped side plates 25 (such as Figure 4 ) are respectively arranged on both sides of the two strip-shaped side panels 27, and each of the special-shaped side panels 25 is provided with a special-shaped chute 28, which is composed of a horizontal groove 29 and an inclined groove 30 connected end to end (as shown in Fig.11 As shown), and the inclined groove 30 is close to the strip side plate 27, and a limit pin 31 that passes through the special-shaped slide groove 28 is fixed on the end of each strip side plate 27. The connecting block 22 fixes the two special-shaped side plates 25 together, and the slide bar 23 is horizontally fixed to the connecting block 22, and the slide bar 23 passes through the lower end of the vertical plate 16. The spring 24 is horizontally sleeved on the slide bar 23, and the two ends of the spring 24 are respectively in conflict with the vertical plate 16 and the connecting block 22. A limit nut 32 (as shown in FIG. Figure 4 As shown), each No. 2 slide 5 is fixedly provided with a push frame 33 (combined with the connection block 22) corresponding to the connection block 22. Figure 4 and Fig.13 ).

[0024] In the initial state, the spring 24 releases its elastic force, and the connecting block 22 is pushed by the spring 24 to extend toward the corresponding push frame 33 (such as Figure 4As shown in the figure, at this time, the limit nut 32 provided on the end of the slide bar 23 will limit the translation stroke of the slide bar 23 by interfering with the vertical plate 16, so as to prevent the slide bar 23 from sliding off the vertical plate 16. When the connecting block 22 is in the extended state, the limit pin 31 on each strip side plate 27 will be at the top of the inclined groove 30, and at this time the lifting baffle 11 is in the rising state (as shown in the figure). Figure 4 As shown in the figure, when the second slide 5 drives the milling cutter 6 to move toward the workpiece, the push frame 33 provided on the second slide 5 will press against the connecting block 22. Thereafter, as the second slide 5 moves, the connecting block 22 will drive the two special-shaped side plates 25 to move synchronously toward the workpiece. At this time, the limit pin 31 on each strip side plate 27 will slide from the inclined groove 30 into the horizontal groove 29. When the limit pin 31 slides on the inclined groove 30, the two strip side plates 27 will cooperate with the limit pin 31 and the inclined groove 30. The No. 2 support plate 18 is driven to descend, and the No. 2 support plate 18 will drive the strip baffle 19 to descend through the connecting plate 20. In the process of the strip baffle 19 descending, the displacement stroke of the strip baffle 19 is limited by the No. 1 limit rod 21 passing through the No. 1 support plate 17, so as to ensure that the strip baffle 19 can only be displaced in the vertical direction. When the limit pin 31 slides in the horizontal groove 29, the lifting baffle 11 stops descending. At this time, the milling cutter 6 will pass over the lifting baffle 11 to bore and mill the end of the workpiece.

[0025] In order to stabilize the translation of the two profiled side panels 25, the following features are provided: A strip support plate 34 is formed at the lower end of each connecting block 22, and a horizontal No. 2 limiting rod 35 is fixed at both ends of the strip support plate 34. A limiting sleeve 36 fixedly connected to the strip support platform 2 is provided on the side of each No. 2 limiting rod 35, and each No. 2 limiting rod 35 passes through the corresponding limiting sleeve 36.

[0026] When the connecting block 22 is pushed by the pushing frame 33, the connecting block 22 will drive the second limiting rod 35 to move through the strip support plate 34. During this process, the second limiting rod 35 will slide in the corresponding limiting sleeve 36. At this time, the sliding of the two special-shaped side panels 25 is stabilized by the cooperation between the second limiting rod 35 and the limiting sleeve 36.

[0027] In order to show how the mobile arm 10 is displaced, the following features are provided: The top of the strip-shaped support platform 2 is provided with a horizontal strip-shaped receiving groove 37 (such as Fig.12 As shown), a horizontal double-sided threaded rod 38 is rotatably provided in the strip-shaped receiving groove 37, and the double-sided threaded rod 38 is formed with two threaded portions with opposite rotation directions. Two No. 1 threaded sleeves 39 are sleeved on the double-sided threaded rod 38, and the two No. 1 threaded sleeves 39 are respectively matched with the two threaded portions on the double-sided threaded rod 38, and each No. 1 threaded sleeve 39 is fixedly connected to the corresponding flat plate 15.

[0028] When the double-sided threaded rod 38 rotates, the two No. 1 threaded sleeves 39 sleeved on the double-sided threaded rod 38 will rotate, and the rotation directions of the two No. 1 threaded sleeves 39 are opposite. Since the flat plate 15 is limited by the cooperation of the No. 2 limiting rod 35 and the limiting sleeve 36, when the double-sided threaded rod 38 rotates, the No. 1 threaded sleeve 39 will not rotate, and the No. 1 threaded sleeve 39 will only translate along the axial direction of the double-sided threaded rod 38. Finally, the two flat plates 15 are driven towards each other through the translation of the two No. 1 threaded sleeves 39.

[0029] In order to show how the double-sided threaded rod 38 rotates, the following features are provided: The mounting platform 3 is provided with a horizontal strip-shaped through slot 40 (such as Figure 7 As shown in the figure, a horizontal driving rod 41 is rotatably provided in the strip-shaped through groove 40, and the driving rod 41 is perpendicular to the double-sided threaded rod 38. A first bevel tooth 42 is coaxially fixedly provided at one end of the driving rod 41, and a second bevel tooth 43 is coaxially fixedly provided at the middle part of the double-sided threaded rod 38. The first bevel tooth 42 and the second bevel tooth 43 are meshed with each other, and a screw cap 44 is coaxially fixedly connected to the other end of the driving rod 41.

[0030] When the double-sided threaded rod 38 needs to be rotated, the screw cap 44 is turned to drive the driving rod 41 to rotate. When the driving rod 41 is rotated, the driving rod 41 will drive the second bevel gear 43 to rotate through the first bevel gear 42, thereby driving the double-sided threaded rod 38 to rotate through the second bevel gear 43.

[0031] In order to show how the first slide 4 and the second slide 5 slide on the mounting platform 3 and the strip support platform 2 respectively, the following features are set: Two horizontal No. 1 electric slide rails 45 are fixed on the top of the mounting platform 3, and two No. 1 electric slide blocks 46 (such as Fig.10 As shown), each No. 1 electric slider 46 slides on the corresponding No. 1 electric slide rail 45, and two horizontal No. 2 electric slide rails 47 are provided under each No. 2 slide 5, and each No. 2 electric slide rail 47 is fixedly connected to the strip support platform 2, and two No. 2 electric sliders 48 are fixedly provided at the bottom of each No. 2 slide 5, and each No. 2 electric slider 48 slides on the corresponding No. 2 electric slide rail 47.

[0032] Each No. 1 slide 4 slides on the corresponding No. 1 electric slide rail 45 through the No. 1 electric slide block 46 , and each No. 2 slide 5 slides on the corresponding No. 2 electric slide rail 47 through the No. 2 electric slide block 48 .

[0033] In order to show how the mobile splint 14 is displaced, the following features are provided: Two symmetrical No. 1 screw slides 49 are fixed on the top of the No. 1 slide 4, and each No. 1 screw slide 49 includes a strip seat 50, a No. 1 screw 51 and two No. 2 threaded sleeves 52. The strip seat 50 is horizontally fixed on the No. 1 slide 4, and the No. 1 screw 51 is horizontally rotated in the strip seat 50. Two threaded portions with opposite rotation directions are formed on the No. 1 screw 51. Each No. 2 threaded sleeve 52 is slidably connected to the strip seat 50, and each No. 2 threaded sleeve 52 is sleeved on the No. 1 screw 51, and the two No. 2 threaded sleeves 52 are respectively matched with the two threaded portions on the No. 1 screw 51, and the two movable clamps 14 in each group of clamps 9 are respectively fixedly connected to the corresponding two No. 2 threaded sleeves 52.

[0034] Each No. 1 screw rod 51 is controlled to rotate by a No. 1 external driving source (not shown in the figure), and the two No. 1 screw rods 51 rotate synchronously. When the No. 1 screw rod 51 rotates, the two No. 2 threaded sleeves 52 will translate, and the translation directions of the two No. 2 threaded sleeves 52 are opposite. When the workpiece needs to be clamped, the two No. 2 threaded sleeves 52 will drive the two movable clamps 14 to move closer to each other.

[0035] In order to show how the lifting seat 7 is installed on the second slide 5, the following features are set: A vertical No. 2 screw slide 53 is fixed on each No. 2 slide 5. The No. 2 screw slide 53 includes a support seat 54, a No. 2 screw 55 and a plurality of fixed rods 56. The support seat 54 is fixed on the No. 2 slide 5. The No. 2 screw 55 rotates vertically on the support seat 54. Each fixed rod 56 is vertically fixed on the support seat 54. A No. 3 threaded sleeve 57 and a plurality of sliding sleeves 58 are fixed on each lifting seat 7. The No. 3 threaded sleeve 57 is sleeved on the No. 2 screw 55. Each sliding sleeve 58 is sleeved on the corresponding fixed rod 56.

[0036] Each No. 2 screw rod 55 is controlled to rotate by a No. 2 external driving source (not shown in the figure). When the No. 2 screw rod 55 rotates, the No. 3 threaded sleeve 57 will be driven to rotate. However, at this time, the rotation of the No. 3 threaded sleeve 57 is limited by the cooperation of the sliding sleeve 58 and the fixed rod 56. In this way, the No. 3 threaded sleeve 57 can only translate along the axial direction of the No. 2 screw rod 55, and finally the No. 3 threaded sleeve 57 is used to drive the corresponding support seat 54 to rise and fall.

[0037] Working principle: This device is used for double-sided boring and milling of rectangular workpieces. When double-sided boring and milling is performed, the workpiece to be bored and milled is placed on the support 13. After the workpiece is placed on the support 13, the workpiece will be between four movable clamping plates 14. Thereafter, the two movable clamping plates 14 in each group of clamping members 9 will translate toward each other. During this process, the two ends of the workpiece will deflect due to the interference of the movable clamping plates 14, so as to align the workpiece. As the movable clamping plates 14 continue to translate, the ends of the workpiece will eventually be clamped by the corresponding two movable clamping plates 14. After the workpiece is clamped, the workpiece will be in an aligned state. Since the distances between the two ends of the workpiece and the two milling cutters 6 may be different at this time, Therefore, it is necessary to correct the distance between the workpiece and the milling cutter 6 thereafter. The specific correction process is as follows: when the workpiece is straightened, the two movable clamping plates 14 will be displaced in the opposite direction. At this time, the workpiece is in a free state. At the same time, the two groups of movable arms 10 in the correction member 8 will be displaced toward each other. At this time, the two lifting baffles 11 will be close to the two ends of the workpiece respectively. The two lifting baffles 11 will respectively contact the two ends of the workpiece, and finally the distances between the two ends of the workpiece and the two milling cutters 6 will be corrected to be consistent. After that, the two movable clamping plates 14 in each group of clamping members 9 will be displaced toward each other again, and finally the workpiece will be clamped. At this time, the workpiece realizes the position straightening and the correction of the distance with the milling cutter 6; When the workpiece is clamped for the second time by the movable clamping plate 14, the two No. 2 slides 5 will translate toward each other, so that the lifting seat 7 arranged on the No. 2 slide 5 will drive the milling cutter 6 to move to the corresponding end of the workpiece. Thereafter, each lifting driving member 12 will drive the corresponding lifting baffle 11 to descend, so that the end of the workpiece is exposed in front of the milling cutter 6. Then, with the continuous feeding of the No. 2 slide 5, each milling cutter 6 will bore and mill the corresponding end of the workpiece. When it is necessary to bore and mill a single side of the workpiece, one of the No. 2 slides 5 will not move, and the other No. 2 slide 5 will continue to feed. Then, one of the milling cutters 6 will bore and mill a single end of the workpiece. During this process, only one lifting baffle 11 will descend, and the other lifting baffle 11 will continue to be in an ascending state. Then, when the milling cutter 6 is boring and milling, the end of the workpiece is blocked by the lifting baffle 11 in an ascending state, so as to overcome the feeding force of the milling cutter 6 and prevent the workpiece from being pushed by the milling cutter 6 during single-sided boring and milling.
