[0031] See also Figures 1 to 3 The present invention's technical solution is applied to a machining mechanism 300 of machining equipment. The machining mechanism 300 includes a spindle box 310 and multiple machining spindles 320. The multiple machining spindles 320 are mounted on the spindle box 310 and arranged in multiple rows and columns. The machining equipment includes a crossbeam 130 and a movable assembly 200. The movable assembly 200 is connected to the side of the crossbeam 130; the side of the spindle box 310 is connected to the side of the movable assembly 200. In the machining mechanism 300 of the present invention, the multiple machining spindles 320 are arranged in multiple rows and columns and are located on one side of the crossbeam 130, achieving a lightweight design and improving the dynamic performance of the equipment.

[0032] See also Figure 1The multi-head processing equipment of the present invention includes a workbench 400, a bed assembly 100, a moving assembly 200 and a processing mechanism 300. The bed assembly 100 includes a base 110, a crossbeam 130 and two columns 120. The two columns 120 are arranged above the two sides of the base 110, and the two ends of the crossbeam 130 are connected to the upper ends of the two columns 120. The moving assembly 200 includes a telescopic mechanism 210, a lifting mechanism 220 and a translation mechanism 230. The telescopic mechanism 210 is arranged on the bed so as to be movable back and forth, and is arranged between the two columns 120 and below the crossbeam 130. The workbench 400 is arranged on the telescopic mechanism 210 so that the workpiece can move along the Y-axis. The lifting mechanism 220 is mounted on the side of the crossbeam 130 for vertical movement, the translation mechanism 230 is mounted on the lifting mechanism 220 for horizontal movement, and the processing mechanism 300 is fixedly mounted on the translation mechanism 230, thereby driving the processing mechanism 300 to move along the Z and X axes. The horizontal and vertical movements of the processing mechanism 300, in conjunction with the forward and backward movement of the worktable 400, allow the processing spindle 320 of the processing mechanism 300 and the workpiece on the worktable 400 to enter the processing area of the equipment. The tool on the processing spindle 320 can then process the workpiece. Specifically, the area directly below the processing spindle 320 where the tool can contact the workpiece is the processing area.

[0033] It is understood that the lifting mechanism 220 and the translation mechanism 230 of the present invention are both disposed on the crossbeam 130. Alternatively, the structural arrangement between the lifting mechanism 220 and the translation mechanism 230 may be such that the translation mechanism 230 is directly connected to the side of the crossbeam 130, while the lifting mechanism 220 is disposed on the side of the translation mechanism 230. With these two structural arrangements, when the processing mechanism 300 moves up and down along the lifting guide rails 221 and horizontally along the translation guide rails 231, the translation mechanism 230 and the lifting mechanism 220, which serve as transmission structures, can be positioned above the processing area, thereby preventing cutting fluid and waste chips from falling into the translation mechanism 230 and the lifting mechanism 220, thereby improving the dynamic performance of the entire machine.

[0034] In some embodiments, the processing mechanism 300 includes a spindle box 310 and multiple processing spindles 320. The multiple processing spindles 320 are set on the spindle box 310 and arranged in multiple rows and columns. The processing equipment includes a crossbeam 130 and a moving assembly 200. The moving assembly 200 is connected to the side of the crossbeam 130, and the side of the spindle box 310 is connected to the side of the moving assembly 200. Specifically, the spindle box 310 is provided with multiple mounting holes, and one processing spindle 320 passes through one mounting hole. The lower side of the processing spindle 320 protrudes from the lower side of the spindle box 310 and is connected to a tool (such as a grinding wheel, etc.). The processing spindle 320 is connected to a spindle driver 330 to drive the tool to process the workpiece. Furthermore, the processing spindle 320 is connected to a pressure sensor 350 for detecting tool pressure, see Figure 2a and Figure 3 The pressure sensor 350 is arranged at the connection position between the processing spindle 320 and the spindle box 310 and / or on the machine tool transmission shaft, which can effectively monitor the pressure applied by the processing spindle 320 to the workpiece during processing.

[0035] It should be noted that the number of the processing spindles 320 can be four, six or eight, etc. Figure 2a and Figure 3 , the processing spindles 320 can be arranged in a variety of forms such as two rows and two columns, two rows and three columns, two rows and four columns or three rows and three columns. The processing mechanism 300 of the present invention adopts a multi-row and multi-column processing spindle 320 arrangement, and the processing spindle 320 is arranged on the side of the beam 130. The processing mechanism 300 is arranged on the translation mechanism 230, which can achieve lightweight design, especially for processing equipment with two main moving machine axes XY, which can effectively improve the dynamic performance of the equipment. Compared with the conventional 1*N spindle arrangement, the N*N spindle arrangement adopted by the present invention has a smaller lateral dimension of the X-axis (i.e., the translation axis), and the screw rod, guide rail, and beam 130 are all shorter, with lower manufacturing costs. At the same time, the span of the beam 130 and the column 120 is much smaller than that of the 1*N arrangement machine tool, and the machine tool rigidity will be higher.

[0036] In some embodiments, the number of spindle drivers 330 is the same as the number of machining spindles 320, and one spindle driver 330 is connected to one machining spindle 320. Figure 1 The number of the spindle drivers 330 is the same as the number of the machining spindles 320 , a tool is connected to the lower side of each machining spindle 320 , and the upper side of each machining spindle 320 protrudes from the spindle box 310 to be connected to a spindle driver 330 .

[0037] In some embodiments, the machining spindle 320 is connected to the spindle driver 330 via a linkage assembly 340, so that one spindle driver 330 can be connected to multiple machining spindles 320. Figure 2a and Figure 2b There are four machining spindles 320 and one spindle driver 330. The linkage assembly 340 is arranged on the upper side of the spindle box 310. The upper sides of the four machining spindles 320 are connected to the lower side of the linkage assembly 340. The rotating shaft of the spindle driver 330 is connected to the upper side of the linkage assembly 340, so that one spindle driver 330 drives four machining spindles 320.

[0038] Furthermore, the number of linkage assemblies 340 can be multiple. For example, if there are two linkage assemblies 340, there are eight machining spindles 320 arranged in two rows and four columns, and there are two spindle drivers 330, then each spindle driver 330 can drive four machining spindles 320. For example, if there are three linkage assemblies, there are six machining spindles 320 arranged in two rows and three columns, and there are three spindle drivers 330, then each spindle driver 330 can drive two machining spindles 320. The above embodiment is for illustrative purposes only and is not intended to be a specific limitation.

[0039] In some specific embodiments, the linkage assembly 340 includes a driving wheel 341 and a plurality of driven wheels 342, and the driving wheel 341 and the driven wheels 342 are driven by a transmission belt 343. Figure 2b There are four machining spindles 320 and six driven wheels 342, four of which are connected to the machining spindles 320, and the remaining two driven wheels 342 are arranged between the above four driven wheels 342. A transmission belt 343 is connected between the driven wheels 342 and the spindle wheels, and the driving wheel 341 is connected to the spindle driver 330, so that the spindle driver drives the machining spindle 320 to rotate through the driving wheel 341 and the driven wheel 342 to process the workpiece.

[0040] In some specific embodiments, the linkage assembly 340 includes a driving gear and multiple driven gears, the main shaft gear is connected to the processing main shaft 320, and a driven gear is connected to each processing main shaft 320. The driving gear is meshed with the driven gear, thereby realizing a spindle driver 330 driving at least two processing main shafts 320 to rotate.

[0041] In some embodiments, the bed includes a base 110, a crossbeam 130 and two columns 120. The two columns 120 are respectively arranged on both sides of the base 110, and the two ends of the crossbeam 130 are respectively connected to the upper ends of the two columns 120. Figure 1The base 110 is shaped like a square block, and the telescopic guide rail 211 is set in the middle of the upper plane of the base 110. The column 120 is shaped like a flat block. The two columns 120 are respectively connected to the two side surfaces of the base 110. The upper side of the column 120 protrudes from the base 110, so that the two columns 120 and the base 110 form a long strip of concave part, and the slide 212 can move in the concave part. The crossbeam 130 is shaped like a directional block. The lower sides of the crossbeam 130 are connected to the upper back side of the column 120, so that the crossbeam 130 is located at the back side of the bed. The lifting assembly, translation assembly and processing mechanism 300 are set in front of the crossbeam 130. Furthermore, an inclined surface is set on the upper front side of the column 120, and the inclined surface is inclined from bottom to top toward the back side, thereby playing a role in avoiding interference between the processing mechanism 300 and the column 120.

[0042] In some embodiments, the crossbeam 130 is disposed on the base 110, and the moving assembly 200 includes a translation mechanism 230 and a lifting mechanism 220. The lifting mechanism 220 is connected to the side of the crossbeam 130, the translation mechanism 230 is connected to the side of the lifting mechanism 220, and the spindle box 310 is connected to the side of the translation mechanism 230. This allows the machining spindles 320 to protrude from the base 110, thereby preventing cutting fluid and waste chips generated during machining from falling onto the base 110 and the transmission structure of the equipment, thereby improving the dynamic performance of the equipment. Furthermore, multiple machining spindles 320 are arranged in multiple rows and columns, achieving a lightweight design. This is particularly effective for XY axis machining, effectively improving the dynamic performance of the equipment.

[0043] It should be noted that in the traditional machine tool structure design, a drainage groove needs to be provided on the upper side of the bed to discharge the cutting fluid or waste chips on the side of the telescopic guide rail 211. The machining spindle 320 of the present invention can protrude from the telescopic guide rail 211 and the bed, and the cutting fluid and waste chips fall directly to the outside of the bed assembly 100, which can effectively avoid falling and accumulating on the bed, thereby making the design of the bed more optimized and eliminating the need to provide a drainage groove, thereby achieving a lightweight design and improving the dynamic performance of the equipment.

[0044] The above description is merely a preferred embodiment of the present invention. The present invention is not limited to the aforementioned embodiments. As long as the technical effects of the present invention are achieved by the same means, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure. Within the scope of protection of the present invention, its technical solutions and / or implementation methods may be modified and varied in various ways.
