Description

Technical Field

[0001] This invention relates to the field of CNC milling machine technology, specifically a rotary table CNC milling machine capable of simultaneously machining multiple workpieces. Background Technology

[0002] A rotary table CNC milling machine capable of simultaneous multi-workpiece machining is a specialized CNC machine for multi-face milling of regularly shaped workpieces. This type of machine is typically equipped with a rotary table on which multiple workpieces can be stacked. An axial clamping force is applied to the workpiece group via a clamping mechanism. Independent spindle heads and milling cutters are arranged opposite each other on both sides of the machine tool, allowing for simultaneous milling of opposite sides of the stacked workpiece group. After one side is machined, the rotary table rotates the workpiece group by a set angle to continue machining the remaining sides, thus achieving efficient multi-workpiece, multi-face machining in a single setup. It is widely used in the mass production of regularly rectangular parts such as valve blocks and connecting blocks.

[0003] However, existing rotary table CNC milling machines of this type have shortcomings in practical applications. On the one hand, existing equipment relies solely on the axial clamping force provided by the upper clamping mechanism to position stacked workpieces. During the machining process, the horizontal lateral cutting force applied to the workpiece by the milling cutters on both sides is resisted only by the friction generated by the axial clamping. Once the cutting resistance increases due to tool wear, it is very easy to cause the workpiece to slip laterally or even fly out, posing a safety risk. On the other hand, when stacking workpieces, the operator needs to manually align multiple workpieces one by one to ensure that the sides of each workpiece are coplanar, which is inconvenient and inefficient, affecting the machining efficiency. Therefore, based on the above problems, a rotary table CNC milling machine that can process multiple workpieces simultaneously is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary table CNC milling machine that can process multiple workpieces simultaneously, so as to solve the problems of existing equipment that rely solely on axial clamping and lack lateral limiting protection, as well as the inconvenience and low efficiency of manual alignment when stacking workpieces.

[0009] Preferably, the clamping assembly consists of an upper hydraulic cylinder and a pressure block rotatably connected to the lower end of the upper hydraulic cylinder, wherein the lower rod of the hydraulic cylinder of the clamping assembly passes through the through-hole and is located on the upper side of the turntable body.

[0010] Preferably, a positioning seat is fixedly connected to the rear side of the column, and a cleaning and collection part is installed at the support frame.

In this invention, through the alignment strip two and the cleaning and collection part, the alignment strip two can laterally limit the stacked workpieces, while the cleaning and collection part can suck in the metal chips generated by milling through the air inlet of the back shell through the exhaust fan, and discharge them into the waste storage shell for centralized collection and storage through the connecting pipe, the manifold hose and the discharge pipe. This reduces the time required for subsequent manual cleaning and maintenance, and solves the problem of metal chips scattering and accumulating and the inconvenience of cleaning and maintenance during the processing of existing rotary table CNC milling machines.

[0015] Please see Figure 1-11 The present invention provides a technical solution: A rotary table CNC milling machine capable of simultaneous machining of multiple workpieces includes a housing 1. A control panel 12 is mounted on the front side of the housing 1. An adjustment support module 2 is mounted on the inner side of the housing 1. The adjustment support module 2 includes a base 21 fixed to the lower inner wall of the housing 1. A Y-axis linear module 22 is fixedly connected to the central slot of the base 21.

A driven gear 234 is meshed with the rear side of the main gear 233. A rotating gear located on the upper side of the driven gear 234 is fixedly connected to the upper side of the housing 231 via a coupling. X-axis linear modules 24 are installed on both the left and right sides of the platform 235 and the base 21. Milling parts 3 for processing stacked workpieces are installed on the upper side of each X-axis linear module 24. A support frame 5 is installed on the upper side of the base 231. The support frame 5 includes a column 51 fixed to the upper side of the base 231. A base plate 52 located on the upper side of the turntable 235 is fixedly connected to the upper end of the column 51. A through-hole 53 is opened on the inner side of the base plate 52. Several guide grooves 54 are opened at equal angles on the outer side of the through-hole 53. A top fixing frame 55 is fixedly connected to the upper side of the base plate 52. A clamping assembly 4 is installed on the lower side of the upper plate of the top fixing frame 55. An adjustment part 6 is installed on the outer side of the base plate 52. The adjustment part 6 includes parts fixed to the front and right end faces of the base plate 52. The housing 61 is connected to the wall. A mounting groove 62 is provided on the upper side of the corner of the housing 61. Rod grooves 63 are provided on the upper side of the housing 61 on both the left and rear sides of the mounting groove 62. A positive and negative threaded rod 64 is rotatably connected to the inner side of each rod groove 63. A second motor 65 is fixedly connected to the left and rear inner walls of the mounting groove 62. The end of the output shaft of the second motor 65 is fixedly connected to the end of the positive and negative threaded rod 64. Both sides of the positive and negative threaded rod 64 are threaded with threaded sleeves 66 that slide in connection with the rod grooves 63. A first connecting arm 67 is fixedly connected to the upper side of the front threaded sleeve 66. A telescopic alignment member 7 located in the left and right guide grooves 54 is installed at the rear end of each connecting arm 67. A second connecting arm 68 is fixedly connected to the upper side of the right threaded sleeve 66. The left end of the second connecting arm 68 is fixedly... Alignment plates 8 are connected to the front and rear guide grooves 54. A conveying part 9 is installed on the front side of the adjustment part 6 to control the extension and retraction of the telescopic alignment members 7 on both sides. The telescopic alignment member 7 includes a tube seat 71 fixedly connected to the rear end of the linkage arm 67. A folded capsule tube 72 is fixedly connected to the upper side of the tube seat 71. A linkage block 73 is fixedly connected to the upper end of the folded capsule tube 72. An alignment plate 74 is fixedly connected to the lower side of the linkage block 73 near the clamping assembly 4 and is slidably connected to the left and right guide grooves 54. The alignment plate 74 is slidably connected to the notch of the tube seat 71. The telescopic alignment members 7 are all located in the direction of the milling part 3. The telescopic alignment members 7 and the milling part 3 are both located on the left and right sides of the turntable body 235 and the clamping assembly 4.Alignment plates 28 are installed on the front and rear sides of the turntable 235 and the clamping assembly 4. This arrangement allows the left and right telescopic alignment pieces 7 and the front and rear alignment plates 28 to be aligned from multiple directions via the adjustment unit 6, ensuring that the sides of each workpiece are coplanar. After alignment, the alignment plates 74 of the left and right telescopic alignment pieces 7 are moved upward by the fluid delivery control of the conveying unit 9, disengaging from the contact with the left and right sides of the stacked workpieces. This allows the left and right milling units 3 to move towards each other under the control of the X-axis linear module 24, milling the left and right sides of the stacked workpieces. The Y-axis linear module 22 can control the rotary table 23 and the stacked workpieces on the upper side to move in the front and back directions, so that the milling unit 3 can perform comprehensive milling on the left and right sides of the stacked workpieces. During the milling process, the alignment strips 28 on the front and back sides of the stacked workpieces can limit their movement in the front and back directions to prevent the stacked workpieces from flying out in the front and back directions during the milling process. The conveying unit 9 includes a liquid tank 91 fixed on the front side of the housing 61. A bidirectional liquid pump 92 is installed on the upper side of the liquid tank 91 and is connected to it. A diversion hose 93 is fixedly connected to the upper side of the bidirectional liquid pump 92 and is connected to it. The rear ends of the diversion hoses 93 are all fixedly connected to the pipe seat 71. The connection allows the conveying unit 9 to supply or extract liquid into the tube seat 71 and the folded capsule 72, thereby controlling the downward extension or upward retraction of the alignment strip 74 of the telescopic alignment member 7. The facing surfaces of the left and right alignment strips 74 and the front and rear alignment strips 8 are all provided with grooves. Pressure sensors 10 are installed in the grooves of both alignment strips 74 and 8. This configuration allows the pressure sensors 10 to detect the contact pressure between the alignment strips 74 and 8 and the stacked workpieces in real time. This serves as a basis for determining whether the alignment is in place in each direction and also provides a reference for the adjustment unit 6. Clamping force feedback ensures that each alignment strip 8 maintains effective lateral restraint on the stacked workpieces during milling, preventing the workpieces from sliding and flying out due to lateral cutting forces. The clamping assembly 4 consists of an upper hydraulic cylinder and a rotating block rotatably connected to the lower end of the upper hydraulic cylinder. The lower rod of the hydraulic cylinder of the clamping assembly 4 passes through the through-hole 53 and is positioned directly above the turntable body 235. This arrangement allows the clamping assembly 4 to axially clamp and fix the stacked workpieces directly above the turntable body 235. Simultaneously, the rotatable connection between the rotating block and the hydraulic cylinder ensures that when the turntable body 235 rotates the stacked workpieces at indexing intervals, the clamping assembly 4 does not interfere with the rotational motion.

[0016] like Figures 2-4 , Figures 6-7 , Figure 11As shown, a positioning seat 56 is fixedly connected to the rear side of the column 51, and a cleaning and collection part 11 is installed at the support frame 5. The cleaning and collection part 11 includes a pair of back shells 111 fixed to the back side of the front and rear aligned strips 8. Air inlets 112 are opened on both the left and right sides of the back shells 111. A connecting pipe 113 is fixedly connected to the upper side of the back shells 111. A connecting hose 114 is fixedly connected to the upper end of the pair of connecting pipes. An exhaust fan 115 is fixedly connected to the rear end of the connecting hose 114. The exhaust fan 115 is fixed to the upper side of the protrusion on the base plate 52. The rear end of the blower 115 is fixedly connected to a pipe 116 that is in a continuous arrangement. A waste storage shell 117 is installed on the upper side of the positioning seat 56. This arrangement allows the cleaning and collection unit 11 to collect and store most of the metal chips that are milled during the milling process, reducing the time required for subsequent manual cleaning and maintenance. The lower end of the pipe 116 is inside the waste storage shell 117. A maintenance cover is detachably connected to the inspection port on the rear side of the outer shell 1. The maintenance cover of the outer shell 1 is located on the rear side of the waste storage shell 117. This arrangement makes it convenient for workers to remove the waste storage shell 117 from the outer shell 1 and the positioning seat 56 for cleaning.

[0017] Workflow: The machining operation of the rotary table CNC milling machine capable of simultaneous machining of multiple workpieces is as follows. Note that all electrical appliances used in this application are externally powered and controlled via the control panel 12. Multiple workpieces to be machined are stacked sequentially on the upper side of the rotary table body 235. The adjustment unit 6 is activated via the control panel 12, synchronously driving the corresponding positive and negative threaded screws 64 of the front and right motors 65 to rotate. This causes the pair of threaded sleeves 66 on the front to move towards each other, driving the connecting arm 67 and the left and right telescopic alignment pieces 7 to move towards each other. The pair of threaded sleeves 66 on the right side move towards each other, driving the connecting arm 68 and the front and rear alignment plates 8 to move towards each other, thereby moving the workpieces from multiple directions (left, right, front, and rear). The stacked workpieces are aligned by compression. After each alignment strip contacts the side of the workpiece, the pressure sensor 10 in the sink detects the contact pressure in real time and feeds it back to the control panel 12. When the pressure in each direction reaches the preset value, it indicates that the sides of each workpiece have been aligned. The above operation completes the rapid alignment of the stacked workpieces. Then, the clamping assembly 4 is activated, and the upper hydraulic cylinder drives the pressure block to press down, axially clamping and fixing the stacked workpieces directly above the turntable body 235. After the upper part is clamped, the bidirectional liquid pump 92 of the conveying unit 9 is activated to deliver liquid to the tube seat 71 and the folded capsule 72 through the diversion hose 93. The folded capsule 72 extends, driving the linkage block 73 and the alignment strip. 74 retracts upwards, disengaging from the left and right sides of the stacked workpiece, thus creating machining space for the milling unit 3; the two milling units 3 are activated, and the two X-axis linear modules 24 control the two milling units 3 to move towards each other and approach the stacked workpiece, simultaneously milling the left and right sides of the stacked workpiece. At the same time, the Y-axis linear module 22 controls the rotary table 23 and the upper stacked workpiece to move in the front-back direction, so that the milling unit 3 can fully mill the left and right sides of the stacked workpiece. During this process, the front and rear alignment strips 28 always maintain lateral restraint on the stacked workpiece in the front-back direction to prevent the workpiece from slipping and flying out due to lateral cutting force; after the left and right sides are milled, the two X-axis linear modules 24... 4. Control the back-to-back displacement of the milling sections 3 on both sides to retract the tool. The adjustment section 6 controls the back-to-back displacement of the front and rear alignment plates 8 to leave room for workpiece rotation. The motor 232 of the rotary table 23 drives the main gear 233 and the driven gear 234 to rotate the turntable body 235 and the stacked workpieces by 90 degrees, so that the front and rear unmachined surfaces face the milling sections 3 on both sides. Then, the adjustment section 6 controls the front and rear alignment plates 8 to move towards each other and reset, and re-clamp and align the stacked workpieces. The reset range is based on the feedback of the front and rear pressure sensors 10, so that the front and rear sides always maintain effective lateral limit. The milling sections 3 on both sides are restarted to perform synchronous milling on the unmachined sides of the stacked workpieces.During the milling process described above, the exhaust fan 115 of the cleaning and collection unit 11 is simultaneously activated. Metal chips generated during milling are drawn in through the air inlets 112 on both sides of the back shell 111, and sequentially discharged into the waste storage shell 117 via the connecting pipe 113, the manifold hose 114, and the discharge pipe 116. After all sides have been processed, the clamping assembly 4 is reset and the stacked workpieces are released. The adjusting unit 6 controls the back-to-back displacement of each alignment strip to release the workpiece, thus removing the processed workpiece from the turntable body 235, completing one multi-workpiece synchronous processing operation.
