Detailed implementation manners

[0032] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0033] As Figure 1 、 Figure 2 shown, a low-energy consumption and high-rigidity main shaft turning and milling composite processing equipment includes a first guide rail 10, and a first jaw 11 and a second jaw 12 provided at both ends of the first guide rail 10. A top frame 13 is fixedly provided at the top of the first guide rail 10. A tool positioning mechanism 2 is slidably mounted on the first guide rail 10. A tool orientation mechanism 3 is provided on the tool positioning mechanism 2. The tool positioning mechanism 2 carries the tool orientation mechanism 3 to move in the horizontal plane. A workpiece fixing mechanism 4 is provided on the side of the tool positioning mechanism 2. A drilling and milling mechanism 7 is provided on the top frame 13.

[0034] As Figure 2 , Figure 5 , Figure 6 shown, the workpiece fixing mechanism 4 includes a transverse slide table three 40 slidably mounted between the first guide rails 10. The transverse slide table three 40 is respectively fixedly arranged on both sides of the tool positioning mechanism 2. Vertical frames 41 are symmetrically arranged on one side of the transverse slide table three 40. The vertical frames 41 are connected with a horizontal frame 42. Swing frames 43 are rotatably mounted at both ends of the horizontal frame 42. An adjustment groove 44 is arranged on the swing frames 43, and a first wrapping frame 45 is slidably mounted in the adjustment groove 44. A first lifting frame 46 is mounted at the central part of the horizontal frame 42. A second wrapping frame 47 is arranged on the first lifting frame 46. The first wrapping frames 45 symmetrically mounted on both sides cooperate with the second wrapping frame 47 to perform triangular locking positioning on the parts. A indexing mechanism 6 is arranged at the end of the tool positioning mechanism 2. The indexing mechanism 6 drives the vertical frames 41 to cooperate with the transverse slide tables three 40 on both sides of the tool positioning mechanism 2 respectively, so as to perform triangular locking positioning on different parts at both ends of the parts.

[0035] Among them, the first lifting frame 46 is installed in a lifting manner through a lifting driving component installed on the horizontal frame 42.

[0036] Specifically, when it is necessary to clamp and lock any part of the shaft-like part, the rotatably mounted swing frames 43 and the first lifting frame 46 are combined to form an enclosure around the outer circle of the shaft-like part. Triangular positioning and locking are formed by the contact between the first wrapping frames 45 movably mounted on the swing frames 43 and the second wrapping frames 47 fixedly arranged on the horizontal frame 42, so as to complete the clamping and positioning of the shaft-like part. At the same time, the indexing mechanism 6 can be combined to adjust the workpiece fixing mechanism 4 to both sides of the tool positioning mechanism 2. Combining the tool positioning mechanism 2 and the first guide rails 10 can realize the clamping and positioning of any position of the shaft-like part. Then, combining the drilling and milling processing mechanism 7 on the top frame 13 can realize processing operations such as drilling and milling on the surface of the shaft-like part, effectively reducing the time for re-clamping and positioning the shaft-like part during the process of switching processing procedures and improving the processing efficiency of the parts.

[0037] Further, as Figure 5 , Figure 6 , Figure 7As shown, insertion slots 400 are provided on both sides of the horizontal sliding table three 40. The vertical frame 41 is slidably clamped with the insertion slots 400. Locking slots one 430 are uniformly arranged on the swing frame 43 along the direction of the adjustment slot 44. A locking pin one 450 is installed between the locking slots one 430 and the wrapping frame one 45. Matching slots 431 are uniformly arranged on the side of the swing frame 43. Horizontal locking slots two 460 are uniformly arranged at both ends of the lifting frame one 46. The locking slots two 460 are locked and installed with the matching slots 431 through locking pins two 461. Contact rollers 49 are rotatably installed on the inner sides of the wrapping frame one 45 and the wrapping frame two 47. The contact rollers 49 are in contact with the surface of the part.

[0038] Specifically, the wrapping frame one 45 is adjustably installed through the adjustment slot 44. At the same time, the position of the wrapping frame one 45 is fixed by combining the locking pin one 450. When both ends of the lifting frame one 46 are locked with the swing frame 43 through the locking pins two 461 respectively, a triangular stable structure is formed between the lifting frame one 46 and the swing frame 43, so as to realize the locking and positioning of the outer surface of the shaft part. During operation, first control the lifting frame one 46 to adjust the height so that the wrapping frame two 47 contacts the bottom of the shaft part. Then control the swing frame 43 to rotate, and at the same time adjust the position of the wrapping frame one 45 in the insertion slot 400 so that the wrapping frames one 45 on both sides respectively abut against both sides of the part. At this time, the wrapping frame one 45 is locked through the locking pin one 450 respectively, and the locking and positioning between the lifting frame one 46 and the swing frame 43 are completed by combining the locking pins two 461.

[0039] Further, as Figure 7 shown, a retaining pin 401 is provided at the edge of the horizontal sliding table three 40. A clamping slot 403 is provided inside the horizontal sliding table three 40. The retaining pin 401 is slidably clamped with the clamping slot 403. The retaining pin 401 is connected with a longitudinal screw two 402.

[0040] Specifically, the horizontal sliding table three 40 is detachably installed through the movably installed retaining pin 401 and the longitudinal screw two 402, so as to realize the quick disassembly and connection between the workpiece fixing mechanism 4 and the guide rail one 10. When compound machining is required, this part of the structure can be assembled with the guide rail one 10.

[0041] Further, as Figure 3 shown, the tool positioning mechanism 2 includes a horizontal sliding table one 20 slidably installed with the guide rail one 10. A longitudinal slide rail 21 is provided on the horizontal sliding table one 20. A longitudinal sliding table one 22 is slidably installed on the longitudinal slide rail 21. A longitudinal screw one 23 and a turntable one 24 are connected between the longitudinal sliding table one 22 and the longitudinal slide rail 21. The tool orientation mechanism 3 is connected with the longitudinal sliding table one 22.

[0042] Specifically, the movable installation of the horizontal slide 1 20 and the longitudinal slide 1 22 enables flexible adjustment of the tool on the horizontal plane. Among them, the longitudinal slide 1 22 is slidably clamped between the longitudinal slide rails 21. At the same time, the inside of the longitudinal slide 1 22 is threadedly connected to the first longitudinal screw 23 to form a threaded driving pair, and the first longitudinal screw 23 is rotatably installed at both ends of the longitudinal slide rails 21. When the first turntable 24 is rotated, it will drive the first longitudinal screw 23 to rotate, and under the action of the threaded driving pair, the longitudinal slide 1 22 is driven to slide back and forth on the longitudinal slide rails 21.

[0043] Further, as Figure 3 , Figure 4 shown, the tool orientation mechanism 3 includes a second horizontal slide 30. The second horizontal slide 30 is horizontally slidably installed between the longitudinal slide 1 22 through a first horizontal screw 31. A fixed frame 34 is provided on the upper side of the second horizontal slide 30. An arc-shaped groove 36 is provided on the surface of the second horizontal slide 30. The length of the arc-shaped groove 36 is one-fourth of a circle. A mating slider 37 is slidably installed in the arc-shaped groove 36. An expansion rod 38 is connected to the mating slider 37. A support seat 39 is provided at the end of the expansion rod 38. A first tool head 33 is placed on the support seat 39. A first locking bolt 311 and a second locking bolt 312 are respectively provided on the fixed frame 34. The second horizontal slide 30 and the fixed frame 34 are rotatably installed between the longitudinal slide 1 22 through a rotating shaft 35 provided at the edge. A horizontal chute 220 is provided at the edge of the longitudinal slide 1 22. A positioning rod 313 is slidably installed in the horizontal chute 220. A positioning bolt 314 is provided between the positioning rod 313 and the second horizontal slide 30.

[0044] Among them, the second horizontal slide 30 is slidably clamped between the longitudinal slide 1 22. At the same time, the second horizontal slide 30 is threadedly connected to the first horizontal screw 31 to form a threaded driving pair. When the first horizontal screw 31 is rotated, it will drive the second horizontal slide 30 to slide horizontally back and forth on the longitudinal slide 1 22.

[0045] Among them, the rotating shaft 35 is connected to form a whole with the fixed frame 34 and the second horizontal slide 30, and the rotating shaft 35 extends and inserts into the inside of the longitudinal slide 1 22 to be rotatably installed with the longitudinal slide 1 22. The whole formed by the rotating shaft 35, the fixed frame 34 and the second horizontal slide 30 is manually driven to rotate and adjust the installation angle.

[0046] Among them, the expansion rod 38 is electrically driven and is a product of the prior art, and its specific structure and driving method will not be elaborated.

[0047] Specifically, the first cutter head 33 is fixedly installed between the support base 39 and the first locking bolt 311 and the second transverse slide 30. At this time, the first cutter head 33 radially points to the surface of the part, facilitating the turning processing of the surface of the part. When turning or reaming the end of the part is required, first loosen the first locking bolt 311, control the movement of the support base 39 to the position of the mating slider 37 by combining the telescopic rod 38, then drive the first cutter head 33 to rotate 90 degrees by combining the arc groove 36, and lock the first cutter head 33 by combining the second locking bolt 312. The first cutter head 33 can be driven to point to the end of the part by combining the first guide rail 10 and the tool positioning mechanism 2, thus completing the corresponding part processing operation.

[0048] More specifically, in order to perform the above processing operations on both ends of the part, the second transverse slide 30 rotates 90 degrees between the rotating shaft 35 and the first longitudinal slide 22. At this time, the arc groove 36 swings 90 degrees, and repeating the above operation will cause the first cutter head 33 to point to the other end of the part, thus performing turning or reaming operations.

[0049] Further, as Figure 2 、 Figure 3 Figure 8 、 Figure 9 、 Figure 10 shown, a longitudinal translation mechanism 5 is further provided between the tool positioning mechanism 2 and the workpiece fixing mechanism 4. The longitudinal translation mechanism 5 includes a translation plate 55 inserted between the vertical frames 41. A horizontal air cylinder 56 is fixedly installed on one of the vertical frames 41. The translation plate 55 is connected to the horizontal air cylinder 56. Two groups of mating holes 57 are provided at the end of the translation plate 55. The end of the first longitudinal slide 22 is provided with a first connecting plate 50 and a second connecting plate 51. A lifting motor 53 is provided on the first connecting plate 50. The output end of the lifting motor 53 is connected with two groups of clamping columns 54. Corresponding to the two groups of clamping columns 54 on the second connecting plate 51, docking holes 52 are provided. The distance between the two groups of mating holes 57 is equal to the distance between the clamping columns 54.

[0050] Specifically, since the first longitudinal slide 22 can perform longitudinal displacement, the clamping columns 54 are driven by the lifting motor 53 to cooperate with the mating holes 57 on the translation plate 55 and finally rise to lock with the docking holes 52 on the second connecting plate 51. During this process, the translation plate 55 rises to drive the vertical frame 41 away from the third transverse slide 40. At this time, driven by the tool positioning mechanism 2, the part is fixed to the end of the first longitudinal slide 22 by combining the workpiece fixing mechanism 4 and moves back and forth together with the first longitudinal slide 22, thus cooperating with the drilling and milling mechanism 7 at the top for drilling or milling processing.

[0051] Further, the first connecting plate 50, the second connecting plate 51, the lifting motor 53, and the clamping columns 54 are symmetrically arranged at the end of the first longitudinal slide 22.

[0052] Furthermore, as shown in Figure 2 , Figure 8 , Figure 9 , the indexing mechanism 6 includes a third connecting plate 60 provided at the end of the first longitudinal slide 22. The third connecting plate 60 is arranged at the left and right symmetric positions on the end face of the first longitudinal slide 22. A rotary motor 61 is provided on the third connecting plate 60. The rotary motor 61 is connected to a rotary frame 62. A second lifting cylinder 63 is provided at the end of the rotary frame 62. The second lifting cylinder 63 is connected to a second lifting frame 64. Plug columns 65 are symmetrically arranged on the second lifting frame 64. The plug columns 65 are hollow. A telescopic column 66 is arranged inside the plug columns 65. A clamping joint 67 is provided at the end of the plug column 65. The clamping joint 67 is opened under the drive of the telescopic column 66 and is locked and fitted with the mating hole 57.

[0053] Among them, the telescopic column 66 is also electrically driven and is a product of the prior art, and its specific structure and driving method will not be elaborated herein.

[0054] Specifically, when it is necessary to adjust the workpiece fixing mechanism 4 on both sides of the tool positioning mechanism 2, the second lifting cylinder 63 drives the plug column 65 to cooperate with the mating hole 57 on the translation plate 55. The telescopic column 66 is combined to make the clamping joint 67 open, so that the plug column 65 is locked with the translation plate 55. Then, the second lifting cylinder 63 drives the vertical frame 41 to disengage from the third transverse slide 40. The rotary motor 61 drives the vertical frame 41 and the upper structure as a whole to rotate 180 degrees. Finally, the vertical frame 41 is mutually fitted with the third transverse slide 40 on this side, thereby realizing the indexing of the workpiece fixing mechanism 4 and realizing the clamping and positioning of different parts at both ends of the part, and cooperating with the machining operation.

[0055] Furthermore, as shown in Figure 11 , the drilling and milling machining mechanism 7 includes a vertically arranged vertical slide rail 71 and a horizontally arranged second guide rail 70. The end of the second guide rail 70 is slidably installed between the vertical slide rails 71. A third lifting cylinder 74 is arranged between the top frame 13 and the second guide rail 70. A fourth transverse slide 73 is slidably installed on the second guide rail 70. Suspension plates 76 are symmetrically arranged at the bottom of the fourth transverse slide 73. A power motor 77 and a second cutter head 72 are rotatably installed between the suspension plates 76. An angle adjustment motor 75 is provided on the suspension plate 76. The output end of the angle adjustment motor 75 is connected to the power motor 77.

[0056] Specifically, the second guide rail 70 combines with the lifting cylinder three 74 and the vertical slide rail 71 for height adjustment, and the horizontal slide table four 73 is electrically installed between the second guide rail 70, so as to adjust the positions of the power motor 77 and the second tool head 72, and combine with the angle adjustment motor 75 to control the angle of the second tool head 72, realizing multi-angle and multi-point flexible machining of parts.

[0057] The working principle of the embodiment of the present invention is:

[0058] Such as Figures 1-11As shown, when it is necessary to clamp and lock any part of the shaft-like part, the swing frame 43 installed for rotation and the first lifting frame 46 are combined to form an enclosure around the outer ring of the shaft-like part. The triangular positioning and locking are formed by the contact of the first wrapping frame 45 movably installed on the swing frame 43 and the second wrapping frame 47 fixedly arranged on the horizontal frame 42 with the outer ring of the shaft-like part, so as to complete the clamping and positioning of the shaft-like part. At the same time, the workpiece fixing mechanism 4 can be adjusted to both sides of the tool positioning mechanism 2 by combining the indexing mechanism 6. By combining the tool positioning mechanism 2 and the first guide rail 10, the clamping and positioning of any position of the shaft-like part can be realized. Then, by combining the drilling and milling mechanism 7 on the top frame 13, the processing operations such as drilling and milling on the surface of the shaft-like part can be realized, effectively reducing the time for re-clamping and positioning the shaft-like part during the process of switching processing procedures and improving the processing efficiency of the part. The first wrapping frame 45 is adjustably installed through the adjustment groove 44, and at the same time, the position of the first wrapping frame 45 is fixed by combining the first locking pin 450. When the two ends of the first lifting frame 46 are locked with the swing frame 43 through the second locking pin 461 respectively, a triangular stable structure is formed between the first lifting frame 46 and the swing frame 43, so as to realize the locking and positioning of the outer surface of the shaft-like part. During operation, first control the first lifting frame 46 to adjust the height so that the second wrapping frame 47 contacts the bottom of the shaft-like part. Then control the swing frame 43 to rotate, and at the same time adjust the position of the first wrapping frame 45 in the insertion groove 400 so that the two first wrapping frames 45 on both sides respectively abut against both sides of the part. At this time, the first wrapping frame 45 is locked through the first locking pin 450 respectively, and the locking and positioning between the first lifting frame 46 and the swing frame 43 are completed by combining the second locking pin 461. The first tool head 33 is locked and installed with the second transverse slide 30 by combining the support seat 39 and the first locking bolt 311. At this time, the first tool head 33 radially points to the surface of the part, which is convenient for turning processing of the surface of the part. When it is necessary to perform turning or reaming processing on the end of the part, control the support seat 39 to move to the position of the matching slider 37 by combining the telescopic rod 38, and then drive the first tool head 33 to rotate 90 degrees by combining the arc groove 36. Lock the first tool head 33 by combining the second locking bolt 312. By combining the first guide rail 10 and the tool positioning mechanism 2, the first tool head 33 can be driven to point to the end of the part, so as to complete the corresponding part processing operation. Due to the longitudinal displacement of the first longitudinal slide 22, the clamping column 54 is driven by the lifting motor 53 to cooperate with the matching hole 57 on the translation plate 55, and finally rises and is locked with the docking hole 52 on the second connecting plate 51. During this process, the translation plate 55 rises to drive the vertical frame 41 away from the third transverse slide 40. At this time, driven by the tool positioning mechanism 2, the part is fixed at the end of the first longitudinal slide 22 by combining the workpiece fixing mechanism 4 and moves back and forth together with the first longitudinal slide 22, so as to cooperate with the drilling and milling mechanism 7 at the top for drilling or milling processing.When the workpiece fixing mechanism 4 needs to be adjusted on both sides of the tool positioning mechanism 2, the lifting cylinder II 63 drives the insertion column 65 to cooperate with the mating hole 57 on the translation plate 55. The expansion column 66 is combined to make the clamping head 67 open, so that the insertion column 65 is locked with the translation plate 55. Then, the lifting cylinder II 63 drives the vertical frame 41 to disengage from the transverse slide III 40. The rotation motor 61 drives the vertical frame 41 and the upper structure as a whole to rotate 180 degrees. Finally, the vertical frame 41 is matched with the transverse slide III 40 on this side, so as to realize the indexing of the workpiece fixing mechanism 4, realize the clamping and positioning of different parts at both ends of the part, and cooperate with the machining operation.
