The figure takes 4 machine tool spindles 1 and 4 workpiece spindles as an example for explanation. The workpiece spindles drive the workpieces to rotate around the axis of the workpiece spindles. The machine tool spindle 1 realizes synchronous processing of the 4 workpieces, improves the processing efficiency, and meets the batch processing of the workpieces. The machine tool spindle 1 can move along a first movement direction and a second movement direction in a horizontal plane, and the first movement direction and the second movement direction are perpendicular. The first movement direction is the X-axis direction of the array machine, and the second movement direction is the Z-axis direction of the array machine. As shown Figure 3 As shown, the machine tool spindle 1 moves left and right along the X-axis direction, and the machine tool spindle 1 moves forward and backward along the Z-axis direction. And the machine tool spindle 1 can rotate around the B-axis direction perpendicular to the X-axis direction and the Y-axis direction. The direction of the workpiece spindle is the same as the X-axis direction, and the workpiece spindle can move up and down along the Y-axis direction in the vertical direction, and the workpiece spindle can also rotate around the A-axis direction perpendicular to the Y-axis direction and the Z-axis direction. Thus, five-axis machining with three linear axes XYZ and two rotation axes AB is realized to meet the processing of complex workpiece structures.

[0034] Preferably, combined Figure 1 , Figure 2 and Figure 3 As shown, the axes of the machine tool spindles 1 are coplanar and all located in the plumb plane, and the distance between two adjacent machine tool spindles 1 is equal. Under the condition of satisfying the workpiece clamping and processing space, the space can be fully utilized, making the structure of the array machine more compact, reducing the volume and mass of the corresponding motion structure, and facilitating the high-speed drive of the drive structure. The axes of the workpiece spindles are coplanar and all located in the plumb plane, and the distance between two adjacent workpiece spindles is equal, ensuring that the workpiece spindles and the machine tool spindles 1 can correspond one to one. The four machine tool spindles 1 move synchronously, and the four workpiece spindles move synchronously. There is no need to perform independent control programming for a single machine tool spindle 1 and a workpiece spindle, which simplifies the control program of the machine tool spindle 1 and the control program of the linkage between the machine tool spindle 1 and the workpiece spindle, so that the action response speed of the machine tool spindle 1 and the workpiece spindle is improved, thereby improving the processing efficiency.

[0035] Preferably, the blade array machine also includes a horizontally arranged bed 3, on which two opposite columns 32 are vertically fixed, and the columns 32 can be fixed to the bed 3 by a first bolt group.

The bottom frame of the fixed frame 31 can be directly fixedly connected to the bed 3 or fixed to the columns 32 and fixedly connected to the bed 3, so as to support the bottom frame of the fixed frame 31.

The fixed seat 21 is fixed to the frame body on the right side of the fixed frame 31 by a third bolt group, and the fixed frame 31 can facilitate the installation and adjustment of the fixed seat 21 and the sliding seat 22. The sliding seat 22 can reciprocate along the X-axis direction and toward the fixed seat 21 to adjust the distance between the fixed seat 21 and the sliding seat 22.

[0039] Specifically, the bottom frame of the fixed frame 31 includes a first support beam 311 and a second support beam 312, which are arranged in parallel and spaced apart and are both located in the same horizontal plane, and both ends of the first support beam 311 and the second support beam 312 are respectively fixedly connected to the frame bodies on both sides of the fixed frame 31. The fixed frame 31 also includes a crossbeam 313, and both ends of the crossbeam 313 are respectively fixed to the tops of the frame bodies on both sides of the fixed frame 31, and the first support beam 311, the second support beam 312, the crossbeam 313, and the frame bodies on both sides of the fixed frame 31 are integrally formed. The first support beam 311, the second support beam 312, the crossbeam 313, and the frame bodies on both sides of the fixed frame 31 form a frame structure to improve the rigidity of the structure and prevent structural deformation.

[0040] Specifically, a chip discharge opening is provided on the bed 3 , and the chip discharge opening corresponds to the space surrounded by the first support beam 311 , the second support beam 312 and the two side frames of the fixed frame 31 , so that the chips of the workpiece fall into the chip discharge opening and are discharged.

[0041] Specifically, a chip removal groove is provided on the bed 3, and the chip removal groove is located at the lower part of the chip removal opening and is connected to the lower outlet of the chip removal opening. A chain plate type chip removal device can be installed in the chip removal groove to realize the discharge and recovery of chips and cutting fluid.

[0042] Preferably, a spindle slide 11 that moves along the X-axis direction is provided on the bed 3. The spindle slide 11 is a cavity structure with a cross-section similar to a U-shape, and the opening direction of the U-shape is set along the Z-axis direction. The U-shaped cavity of the spindle slide 11 is provided with a sliding box seat 12, and the sliding box seat 12 can move back and forth along the Z-axis direction relative to the spindle slide 11. An installation space is provided in the sliding box seat 12 and a spindle frame 13 is installed. The spindle frame 13 is connected to the sliding box seat 12 through stepped shafts at the upper and lower ends. A machine tool spindle 1 set along the Z-axis direction is provided in the spindle frame 13. The machine tool spindle 1 can rotate around the B-axis direction driven by the spindle frame 13. The machine tool spindle 1 can realize feeding in the X-axis direction driven by the spindle slide 11; the machine tool spindle 1 can realize feeding in the Z-axis direction driven by the sliding box seat 12.

[0043] Specifically, a third driving assembly is installed on the bed 3 to drive the spindle slide 11 to move, and a corresponding third guide rail assembly is also provided on the bed 3 to guide the spindle slide 11. A fourth driving assembly is provided between the spindle slide 11 and the sliding box seat 12 to drive the sliding box seat 12 to move; a fourth guide rail assembly is also provided between the spindle slide 11 and the sliding box seat 12 to support and guide the sliding box seat 12. In addition, guide rail mounting seats are integrally formed on both sides of the sliding box seat 12, and the two end surfaces of the guide rail mounting seat and the U-shaped opening of the spindle slide 11 are opposite to each other up and down, and a fifth guide rail assembly is provided between the guide rail mounting seat and the spindle slide 11 to further guide the sliding box seat 12. The spindle slide 11 sits on the bed 3, and the sliding box seat 12 is arranged on the spindle slide 11. The spindle slide 11 and the sliding box seat 12 only move along the horizontal plane. Compared with the up and down movement, the horizontal movement does not need to overcome the self-weight of the movement structure and the weight of the drive structure, so that the third drive assembly is easier to drive the spindle slide 11 and the fourth drive assembly is easier to drive the sliding box seat 12. Therefore, the size and weight of the components of the drive structure, such as the motor, can be smaller, so that the weight of the movement structure is minimized. This arrangement allows most of the structure of the third drive assembly to be arranged on the bed 3 to ensure that the weight of the movement structure is not affected by the stroke. When the stroke needs to be increased, it is only necessary to increase the length of the bed 3 and the length of the third drive assembly to ensure that the weight of the movement structure is minimized. And because the weight of the movement structure is relatively small, the inertia of the movement structure is also reduced accordingly. Therefore, the third drive assembly and the fourth drive assembly are easier to realize drive control and high-speed drive, thereby improving the processing efficiency of the array machine and facilitating the array machine to achieve higher precision.

[0044] Specifically, the first support beam 311 and the second support beam 312 are provided with a fifth driving assembly to drive the sliding seat 22 to move along the X-axis direction, and the first support beam 311 and the second support beam 312 are provided with a sixth guide rail assembly for guidance. The crossbeam 313 is provided with a sixth driving assembly to synchronously drive the sliding seat 22 together with the fifth driving assembly to ensure that the upper and lower ends of the sliding seat 22 move in unison to prevent the sliding seat 22 from deforming. Moreover, the synchronous driving of the sixth driving assembly and the fifth driving assembly can realize the high-speed movement of the sliding seat 22, which is convenient for the sliding seat 22 to quickly switch according to the size of the workpiece. The crossbeam 313 is also provided with a seventh guide rail assembly for guidance.

[0045] Specifically, the driving component can use a ball screw linear module or a linear motor to achieve high-speed driving of the motion structure.

[0046] Specifically, a seventh driving assembly is provided on the sliding box seat 12 to drive the spindle frame 13 to rotate, thereby realizing the rotation of the machine tool spindle 1 around the B-axis direction.

[0047] Specifically, the column 32 and the fixed frame 31 are located on the front side of the upper surface of the bed 3, and the third drive assembly and the spindle slide 11 are located on the rear side of the upper surface of the bed 3. This layout makes the structural weight more evenly distributed front to back, preventing weight concentration from affecting the overall rigidity of the structure and thus affecting the processing accuracy.

[0048] Preferably, a tool magazine is provided on the bed 3, and the tool magazine is provided on one side of the workpiece spindle along the X-axis direction, and the tool magazine is located on one side of the column 32. The tool magazine cooperates with the machine tool spindle 1 to realize tool change.

[0049] Preferably, the tool magazine includes a knife disc 41 and a tool claw assembly; a plurality of tool claw assemblies are evenly distributed on the outer periphery of the knife disc 41; each tool claw assembly includes a first tool clamp 42 and a second tool clamp 43 with openings facing opposite directions; the first tool clamp 42 and the second tool clamp 43 of each tool claw assembly can simultaneously fix two tools of different lengths on the knife disc 41 along the radial direction of the knife disc 41; an idle tool picking position is formed between two adjacent tool claw assemblies, where the tools can be clamped in or out of the tool clamps. A fan-shaped idle tool picking position is reserved between two adjacent tool claw assemblies, and a long knife in one tool claw assembly and a short knife in its adjacent tool claw assembly share an idle tool picking position, so that the distance between the two adjacent tool claw assemblies can be reduced, thereby saving space on the knife disc 41; and the two long and short tools are located on the same tool claw assembly, and the tool claw assembly and the adjacent tool claw assemblies on both sides share an idle tool picking position, which can save an idle tool picking position, so that more tools can be arranged on the knife disc 41.

[0050] Preferably, the shape of the tool disc 41 is a regular polygon, the first tool clamp 42 and the second tool clamp 43 are set at a certain angle, the first tool clamp 42 and the second tool clamp 43 are located on two adjacent sides of the regular polygon, and the angle between the first tool clamp 42 and the second tool clamp 43 is set according to the angle between the two adjacent sides of the regular polygon. When any tool clamp is rotated to correspond to the tool changing position of the machine tool spindle 1, the edge of the regular polygon where the tool clamp is located is in the X-axis direction, ensuring that the direction in which the tool in the tool clamp is separated from the tool clamp is consistent with the X-axis direction, and the axial direction of the tool in the tool clamp is consistent with the Z-axis direction. The machine tool spindle 1 aligns the tool in the tool clamp and then pulls the tool, and the machine tool spindle 1 moves along the X-axis direction to separate the tool from the tool clamp. The tool changing process only requires the rotation of the tool disc 41 and the movement of the machine tool spindle 1 in two linear directions. The tool is changed through the machine tool spindle 1, which saves the tool changing device, simplifies the tool changing action, and can improve the efficiency of tool changing.

[0051] Preferably, a rotating shaft 44 and an eighth driving assembly are provided on the bed 3, and the axis of the rotating shaft 44 is along the Y-axis direction. The cutter disc 41 is mounted on the rotating shaft 44, and the eighth driving assembly drives the rotating shaft 44 to drive the cutter disc 41 to rotate. The rotating shaft 44 drives the cutter disc 41 to rotate so as to rotate the corresponding tool on the cutter disc 41 to the corresponding tool changing position of the machine tool spindle 1 as required.

[0052] Preferably, a plurality of layers of cutter discs 41 and cutter claw assemblies are provided on the rotating shaft 44 along the axial direction of the rotating shaft 44 for installing more cutters.

[0053] Preferably, the number of layers of the cutter discs 41 on the rotating shaft 44 is the same as the number of the machine tool spindles 1 , and the multi-layer cutter discs 41 correspond to the four machine tool spindles 1 respectively, and are used for tool changing of the four machine tool spindles 1 .

[0054] Preferably, the distance between the multiple layers of tool discs 41 on the rotating shaft 44 along the axial direction of the rotating shaft 44 is the same as the distance between the four machine tool spindles 1 of the machine tool along the axial direction of the rotating shaft 44, so that when the four machine tool spindles 1 are changing tools, the tool disc 41 only needs to rotate without making linear motion, and the machine tool spindle 1 only needs to move in two linear directions, which saves the tool changing action and is conducive to simplifying the programming of the tool changing process control program, making it easier for the tool disc 41 and the machine tool spindle 1 to achieve higher motion accuracy and improve the tool changing speed.

[0055] Preferably, the tools on each layer of the tool disc 41 are arranged in a consistent manner, so that the multi-layer tool discs 41 can move synchronously, and the four machine tool spindles 1 can change tools synchronously, further simplifying the tool changing steps, making it easier to program the tool changing process control program, and further improving the tool changing speed, thereby reducing processing auxiliary time and improving processing efficiency.

[0056] Example 2

[0057] This embodiment provides a method for manufacturing a blade array machine, comprising the following steps:

[0058] Step 1: Install several machine tool spindles and adjust the axes of several machine tool spindles to be parallel.

[0059] Specifically, the spindle frame is first processed so that there is installation space for a plurality of machine tool spindles in the spindle frame, and then the plurality of machine tool spindles are installed in the spindle frame, and then the axes of the plurality of machine tool spindles are adjusted to be parallel to each other.

[0060] Adjustment steps include:

[0061] Install the inspection rod on several installed machine tool spindles, place several machine tool spindles horizontally on the three-dimensional coordinate measuring machine, measure the parallelism of the side busbars of the inspection rod by the three-dimensional coordinate measuring machine, and adjust the machine tool spindles so that the side busbars of several inspection rods are parallel to each other. Specifically, place the spindle frame horizontally on the three-dimensional coordinate measuring machine so that the axes of several machine tool spindles are in the horizontal direction. Operate the three-dimensional coordinate measuring machine and use open-line scanning to scan the side busbars of the inspection rod. Set the starting point and the ending point on the outer peripheral surface of the inspection rod. The probe of the three-dimensional coordinate measuring machine scans from the starting point along the side busbar direction of the inspection rod to the ending point according to the preset step length, collect data points and measure the side busbar shape of the inspection rod. Measure the side busbar shape of each inspection rod in turn, and use the three-dimensional coordinate measuring machine to calculate the parallel error of the side busbar of each inspection rod. According to the measurement results, the matching grinding pad between the machine tool spindle and the spindle frame is ground for leveling, and then the side generatrix of each inspection rod is repeatedly measured by the three-coordinate measuring machine. If the side generatrix of each inspection rod still does not reach the tolerance range, the matching grinding pad is repeatedly ground and measured until the side generatrix of each inspection rod is parallel to each other.

[0062] The position of the machine tool spindle end face is detected by a three-coordinate measuring instrument, and the machine tool spindle is adjusted to make the machine tool spindle end faces coplanar. Specifically, the three-coordinate measuring instrument is operated, and the machine tool spindle end face is scanned by face scanning. The starting point and direction point are set on the machine tool spindle end face. The probe of the three-coordinate measuring instrument scans from the starting point to the direction point according to the preset scanning length and scanning width, and the data points are collected to measure the shape and position of the machine tool spindle end face. The end faces of each machine tool spindle are measured in turn, and the position error of each machine tool spindle end face is calculated by the three-coordinate measuring instrument. According to the measurement situation, the matching grinding pad between the machine tool spindle and the spindle frame is ground to adjust the position, and then the position error of each machine tool spindle end face is repeatedly measured by the three-coordinate measuring instrument. If it does not reach the tolerance range, the matching grinding pad is repeatedly ground and measured until the end faces of each machine tool spindle are coplanar.

[0063] The height of the test rod busbar is detected by a three-coordinate measuring instrument, and the machine tool spindle is adjusted to make the height of the machine tool spindle axis the same. Specifically, the three-coordinate measuring instrument is operated, and the side busbar of the test rod after adjustment is scanned by open-line scanning. The starting point and the end point are set on the outer peripheral surface of the test rod. The probe of the three-coordinate measuring instrument scans from the starting point along the side busbar direction of the test rod to the end point according to the preset step length, and the data points are collected to measure the shape of the side busbar of the test rod. The shape and position of the side busbar of each test rod are measured in turn, and the height difference of the side busbar of each test rod is calculated by the three-coordinate measuring instrument. According to the measurement situation, the positioning holes of the machine tool spindle and the spindle frame are manually scraped and grinded to adjust the height of each test rod. The height difference of the side busbar of each test rod is repeatedly measured by the three-coordinate measuring instrument. If it does not reach the tolerance range, the positioning holes of the machine tool spindle and the spindle frame are continued to be scraped and grinded until the height of the side busbar of each test rod is the same, thereby ensuring that the height of the spindle axis of each machine tool is the same.

[0064] Step 2: Install the same number of workpiece spindles as the machine tool spindles.

[0065] Specifically, a first workpiece spindle box and a second workpiece spindle box are firstly processed, and first workpiece spindles equal in number to the machine tool spindles are installed in the first workpiece spindle box, and second workpiece spindles equal in number to the machine tool spindles are installed in the second workpiece spindle box.

[0066] Step 3: Adjust the position of the workpiece spindle so that the axes of the workpiece spindles are parallel to each other, the spacing between adjacent workpiece spindle axes is equal to the spacing between the corresponding machine tool spindle axes, and the end faces of the workpiece spindles are coplanar.

[0067] Adjustment steps include:

[0068] Install the inspection rods on the installed workpiece spindles equal to the number of the machine tool spindles, place the workpiece spindles equal to the number of the machine tool spindles horizontally on the three-dimensional coordinate measuring machine, measure the side generatrix of the inspection rod and the end face of the workpiece spindle by the three-dimensional coordinate measuring machine, and adjust the workpiece spindles so that the axes of the workpiece spindles are parallel to each other in the same plane and the end faces are coplanar. Specifically, install the inspection rods on the installed first workpiece spindles and the second workpiece spindles, respectively place the first workpiece spindle box and the second workpiece spindle box horizontally on the three-dimensional coordinate measuring machine, so that the axes of the first workpiece spindle and the second workpiece spindle are in the horizontal direction; measure the side generatrix of each inspection rod by the three-dimensional coordinate measuring machine, grind the matching grinding pad between the first workpiece spindle box and the first workpiece spindle according to the measurement situation, so that the axes of the first workpiece spindle are parallel to each other in the same plane; grind the matching grinding pad between the second workpiece spindle box and the second workpiece spindle according to the measurement situation, so that the axes of the second workpiece spindle are parallel to each other in the same plane. The end faces of the first workpiece spindles are measured by a three-coordinate measuring machine, and the grinding pad between the first workpiece spindle box and the first workpiece spindle is ground according to the measurement results to make the end faces of the first workpiece spindles coplanar; the grinding pad between the second workpiece spindle box and the second workpiece spindle is ground according to the measurement results to make the end faces of the second workpiece spindles coplanar. The height of the inspection bar generatrix is ​​detected by a three-coordinate measuring machine, and the positioning holes of the first workpiece spindle and the first workpiece spindle box are adjusted by manual scraping to make the heights of the first workpiece spindles the same. The positioning holes of the second workpiece spindle and the second workpiece spindle box are adjusted by manual scraping to make the heights of the second workpiece spindles the same.

[0069] The distance between the side busbars of the inspection rods is measured by a three-coordinate measuring machine, and the workpiece spindle is adjusted according to the distance between the machine tool spindles, so that the spacing between the adjacent workpiece spindle axes is equal to the spacing between the corresponding machine tool spindle axes. Specifically, the side busbars of the inspection rods on each first workpiece spindle are measured by a three-coordinate measuring machine, and the spacing of the side busbars of the inspection rods on each first workpiece spindle is calculated by the three-coordinate measuring machine. According to the distance between the corresponding machine tool spindles, the positioning holes of the first workpiece spindle and the first workpiece spindle box are scraped and grinded, so that the distance between the side busbars of the two adjacent inspection rods is equal to the spacing between the corresponding machine tool spindle axes. The method for adjusting the spacing between each second workpiece spindle is the same as the method for adjusting the spacing between the first workpiece spindles, and will not be repeated here. Thereby ensuring that the spacing between the adjacent workpiece spindle axes is equal to the spacing between the corresponding machine tool spindle axes.

[0070] Step 4: Install the adjusted machine tool spindles to the corresponding motion structure, and install the adjusted workpiece spindle to the corresponding motion structure. Specifically, install the adjusted spindle frame and the machine tool spindle inside it into the sliding box seat, install the adjusted first workpiece spindle box and the first workpiece spindle inside it into the fixed seat, and install the adjusted second workpiece spindle box and the second workpiece spindle inside it into the sliding seat.

[0072] Example 3

[0073] This embodiment provides a tool changing method using a blade array machine tool magazine for tool changing, including a machine tool spindle picking up a tool from the tool magazine and the machine tool spindle putting the tool back into the tool magazine:

[0074] Among them, combined Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the machine tool spindle picks up the tool from the tool magazine including the following steps:

[0075] Step 1: Control the tool disc to rotate so that the tool holder on which the tool to be picked up is fixed rotates to a position corresponding to the tool changing position of the machine tool spindle. At this time, the axis of the tool to be picked up is along the Z-axis direction.

[0076] Step 2: Control the machine tool spindle to move along the X-axis direction so that the machine tool spindle moves to the machine tool spindle tool changing position, so that the axis of the machine tool spindle is coaxial with the axis of the tool to be picked up.

[0077] Step 3, control the machine tool spindle to move along the axial direction of the tool to be picked up, that is, the machine tool spindle moves forward along the Z-axis direction until the machine tool spindle broach is clamped with the tool holder of the tool to be picked up.

[0078] Step 4, control the machine tool spindle to move along the X-axis direction, the machine tool spindle drives the tool to be picked up to move along the side direction of separation from the tool holder to separate the tool to be picked up from the current tool holder, and move to the neutral tool picking position.

[0079] Step 5, control the machine tool spindle to move backward along the Z-axis direction, and the machine tool spindle drives the tool to be picked up to move along the axis direction of the tool to the side away from the tool disc, so that the tool to be picked up exits the neutral tool picking position; control the machine tool spindle to move along the X-axis direction, so that the machine tool spindle and the tool move to the processing area.

[0080] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the machine tool spindle puts the tool back into the tool magazine including the following steps:

[0081] Step 1, control the machine tool spindle to move along the X-axis direction so that the machine tool spindle moves to the machine tool spindle tool change position, and the axial direction of the tool to be returned is consistent with the radial direction of the tool disc, that is, the axial direction of the tool to be returned is along the Z-axis direction.

[0082] Step 2: Control the rotation of the cutter disc so that the neutral tool picking position on the side of the cutter disc that is used to fix the tool to be put back is rotated to correspond to the tool changing position of the machine tool spindle.

[0083] Step 3, control the machine tool spindle to move forward along the Z axis direction, and the machine tool spindle drives the tool to be returned to move along the axis direction of the tool toward the side close to the cutter disc until the tool to be returned moves to the neutral tool picking position.

[0084] Step 4: Control the machine tool spindle to move along the X-axis direction, and the machine tool spindle drives the tool to be picked up to move along the side direction where the tool holder is engaged, so that the tool to be picked up is engaged with the current tool holder.

[0085] Step 5: Control the machine tool spindle to pull the tool to release the tool handle to be put back, and the machine tool spindle moves along the axis direction of the tool to the side away from the tool disk, that is, the machine tool spindle moves backward along the Z axis direction away from the tool disk, so that the machine tool spindle is separated from the tool to be put back.
