Description

Technical Field

[0001] This invention relates to the field of machining centers, and more specifically to a tool change position adjustment device and a machining center adjustment method. Background Technology

[0002] Mechanical manufacturing is a core industry of the manufacturing sector, and machining centers play a crucial role in it. The core equipment for high efficiency in machining centers is the tool magazine. Regardless of the type of tool magazine, after installation on a machining center, professional adjustments to the tool change point and spindle orientation, as well as trial runs of the tool change operation, are necessary. If the tool change point shifts due to prolonged operation or the fixing screws loosen, rapid and accurate adjustments are required. Inaccurate or slow tool change point adjustments can lead to problems such as tool collisions and spindle impacts during machining. Therefore, specialized equipment is needed for adjustment to ensure smooth tool changes and meet the high-speed, high-precision requirements of the machining center.

[0003] The traditional method for calibrating tool change points in machining centers currently uses a three-piece tool calibration kit, which has the following limitations: ① It requires multiple tool clamping and loosening operations on the machining center spindle during calibration, making the operation cumbersome; ② Calibration can only be performed in one direction, not simultaneously in the X, Y, and Z directions, requiring multiple adjustments to the tool magazine's fixing screws or adjusting shims, which is time-consuming and labor-intensive; ③ The tool magazine's level can only be tested by using a dial indicator or placing a level in a suitable location, which is not applicable to all tool magazine types; ④ Existing tool change point calibration methods require two or more people to work together, resulting in a certain degree of manpower waste.

[0004] Currently, the industry lacks a solution that can quickly adjust tool change points and save on labor and time costs to a certain extent. Summary of the Invention

[0005] To improve the debugging efficiency of tool change point adjustment in machining centers, a tool change position adjustment device and a machining center debugging method are proposed.

[0017] Preferably, the spindle end assembly includes a conical surface with the first axis as its axis and a first plane perpendicular to the first axis, the first plane facing the cutter arm end assembly;

[0018] The first cross-shaped optical path is disposed on the first plane, and the center line of the first cross-shaped optical path coincides with the first axis.

[0019] Preferably, the cutter arm end assembly includes a cylindrical surface with the second axis as its axis and a second plane perpendicular to the second axis, the second plane being opposite to the first plane;

[0020] The second cross light path is disposed on the second plane, and the center line of the second cross light path coincides with the axis of the cylindrical surface.

[0021] Preferably, the machining center tool change position adjustment device includes a first light source assembly disposed on the spindle end assembly, and / or a second light source assembly disposed on the tool arm end assembly.

[0022] Preferably, a fifth slit perpendicular to the second cross-shaped optical path is provided on the cylindrical surface, and the fifth slit constitutes a third optical path; the third optical path is connected to the second cross-shaped optical path.

[0032] Step 7: Measure the distance between the spindle end assembly and the tool magazine end assembly and input it into the machining center.

This eliminates the risk of mutual compression and improves the accuracy of tool change point adjustments. Attached Figure Description

[0048] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0052] This invention relates to the field of machining centers, and specifically to a machining center debugging device and a machining center debugging method for tool changing position.

[0053] Mechanical manufacturing is a core industry of the manufacturing sector, and machining centers play a crucial role in it. The core equipment for high efficiency in machining centers is the tool magazine. Regardless of the type of tool magazine, after installation on a machining center, professional adjustments to the tool change point and spindle orientation, as well as trial runs of the tool change operation, are necessary. If the tool change point shifts due to prolonged operation or the fixing screws loosen, rapid and accurate adjustments are required. Inaccurate or slow tool change point adjustments can lead to problems such as tool collisions and spindle impacts during machining. Therefore, specialized equipment is needed for adjustment to ensure smooth tool changes and meet the high-speed, high-precision requirements of the machining center.

[0054] The traditional method for calibrating tool change points in machining centers currently uses a three-piece tool calibration kit, which has the following limitations: ① It requires multiple tool clamping and loosening operations on the machining center spindle during calibration, making the operation cumbersome; ② Calibration can only be performed in one direction, not simultaneously in the X, Y, and Z directions, requiring multiple adjustments to the tool magazine's fixing screws or adjusting shims, which is time-consuming and labor-intensive; ③ The tool magazine's level can only be tested by using a dial indicator or placing a level in a suitable location, which is not applicable to all tool magazine types; ④ Existing tool change point calibration methods require two or more people to work together, resulting in a certain degree of manpower waste.

[0055] To improve the debugging efficiency of tool change point debugging in machining centers, a tool change position debugging device and a machining center debugging method are proposed.

[0056] This invention proposes a tool change position adjustment device for machining centers, such as... Figure 1-6 As shown, the machining center includes a machining center spindle and a tool magazine; the tool magazine includes a tool magazine arm; the tool magazine arm is provided with a tool retaining groove, including:

[0057] Spindle end assembly 1 is used to be fixed on the spindle of the machining center, and the spindle end assembly 1 is provided with a first centering structure 101;

[0058] The blade end assembly 2 is used to be fixed in the blade slot, and the blade end assembly 2 is provided with a second centering structure 201;

[0059] A leveling device is used to adjust the level of the cutter arm end assembly 2;

[0060] The spindle end assembly 1 and the tool arm end assembly 2 are adjusted to enable the independent first centering structure 101 and the second centering structure 201 to be aligned by light.

[0061] In existing technologies, the mandrel used for centering is a solid structure. Centering is achieved through this solid mandrel, with one end fixed to the spindle end assembly 1. Adjusting the tool magazine ensures that the tool holder groove of the tool magazine arm is just in contact with and fixed to the tool arm end assembly 2 to complete the adjustment. Due to the rigidity of the mandrel itself, compression inevitably occurs between the tool arm end assembly 2 and the mandrel during adjustment, resulting in low adjustment accuracy and potential damage to the machining center spindle and tool magazine. This application, by adjusting the level of the tool arm end assembly 2 using a leveling device, effectively improves the adjustment accuracy of the tool setting point compared to existing technologies where leveling via the mandrel is difficult due to its rigidity.

[0062] This application uses a first alignment structure 101 and a second alignment structure 201, which are independent of each other, to perform alignment adjustments. This avoids damage caused by rigid compression that may occur during the adjustment process. Since there is no mutual compression deformation, the alignment accuracy is also improved. The first alignment structure 101 and the second alignment structure 201 can be light-based alignment. When the first alignment structure 101 and the second alignment structure 201 are aligned, the light emitted from the first alignment structure 101 illuminates a certain position on the cutter arm end assembly 2, and the light emitted from the second alignment structure 201 illuminates a certain position on the spindle end assembly 1; alternatively, the light emitted from the first alignment structure 101 and the second alignment structure 201 can completely overlap. The light source can be externally installed or integrated into the adjustment device.

[0063] Preferred, such as Figure 1 As shown, the machining center tool change position adjustment device also includes a level 3, which is mounted on the tool arm end assembly 2. The spindle end assembly 1 has a first axis, which is vertical when the spindle end assembly 1 is fixed on the machining center spindle. The tool arm end assembly 2 has a second axis, which is parallel to the first axis when the level 3 is horizontal.

[0064] It should be noted that the first axis and the second axis are virtual axes, introduced for the convenience of explaining the spatial positions of the spindle end assembly 1 and the tool arm end assembly 2.

[0065] In a Cartesian coordinate system, the spindle axis of the machining center is the Z-axis, while the X and Y axes lie in the horizontal plane. The first axis is vertical, extending along the Z-axis. A level 3 is used to make the second axis parallel to the first axis, completing the horizontal adjustment of the tool arm end assembly 2. This process requires maintaining the alignment of the first centering structure 101 and the second centering structure 201. However, in existing technologies, horizontal adjustment is difficult after centering via a mandrel. When horizontal adjustment is performed, the limitations of the physical structure cause compression between the tool arm end assembly and the mandrel, easily damaging the tool arm and even adversely affecting the verticality of the spindle.

[0066] Specifically, the second axis of the tool is kept vertical by using the level 3. The spatial position of the tool arm end assembly 2 is adjusted by adjusting the tool magazine fixing screws, thereby adjusting the second centering structure 201 and the level 3. The spatial position of the spindle end assembly 1 is adjusted by adjusting the three-axis position of the machining center, thereby adjusting the first centering structure 101. The adjustment of the first centering structure 101 and the second centering structure 201 completes the centering of the first centering structure 101 and the second centering structure 201, completing the adjustment in the X and Y axis directions and the horizontal adjustment of the tool arm end assembly. Then, the distance S between the spindle end assembly 1 and the tool arm end assembly 2 is measured and input into the machining center for adjustment (generally by subtracting S), completing the adjustment in the Z axis direction.

[0067] Since the spindle end assembly 1 is fixed on the machining center spindle and the tool arm end assembly 2 is fixed in the tool holder groove, the positional relationship between the machining center spindle and the tool magazine is completed, which means that the tool changing point of the machining center is adjusted so that the tools in the tool magazine can be accurately changed to the machining center spindle.

[0068] While adjusting the tool change point (in the XYZ directions), ensuring the tool magazine and tool changer arm are level improves the efficiency of adjustments in other directions. During the adjustment process, the machining center spindle is vertically aligned, which confirms the spindle's orientation, further improving adjustment efficiency and shortening adjustment time.

[0069] During the debugging process, only one staff member is needed to complete the task, saving manpower.

[0070] Preferred, such as Figure 3 and Figure 5 As shown, the first centering structure 101 includes a first gap 1011 and a second gap 1012 that can intersect.

[0071] The second centering structure 201 includes a third gap 2011 and a fourth gap 2012 that can intersect;

[0072] When the first centering structure 101 and the second centering structure 201 are aligned, the light emitted from the first slit 1011 and the second slit 1012 can enter the third slit 2011 and the fourth slit 2012 respectively; and / or, the light emitted from the third slit 2011 and the fourth slit 2012 can enter the first slit 1011 and the second slit 1012 respectively.

[0073] Example 1: The planar light emitted from the first slit 1011 coincides with the planar light emitted from the second slit 1012; the planar light emitted from the third slit 2011 coincides with the planar light emitted from the fourth slit 2012; and since the first slit 1011 and the second slit 1012 can intersect (that is, the first slit 1011 and the second slit 1012 are not parallel to each other), and the third slit 2011 and the fourth slit 2012 can intersect (that is, the third slit 2011 and the fourth slit 2012 are not parallel to each other), the positional relationships except for the distance between the spindle end assembly 1 and the tool arm end assembly 2 are determined. At this time, the adjustment in the X and Y axis directions is completed. By using the intersecting first slit 1011 and second slit 1012, and the intersecting third slit 2011 and fourth slit 2012, it is possible to better observe and test the overlap of the first slit 1011 and third slit 2011, and the overlap of the second slit 1012 and fourth slit 2012, which is beneficial to improving the debugging accuracy in the X-axis and Y-axis directions.

[0074] Example 2: It is also possible for the first centering structure 101 and the second centering structure 201 to both be positioned as annular gaps. By making the light rings emitted from the two annular gaps overlap, the adjustment can also be completed in the X-axis and Y-axis directions.

[0075] Example 3: Both the first centering structure 101 and the second centering structure 201 are capable of emitting light sources with good linearity. The light emitted by the first centering structure 101 illuminates a specific structure on the cutter arm end assembly 2, and the light emitted by the second centering structure 201 illuminates a specific structure on the spindle end assembly 1 for centering.

[0076] Preferably, the first slit 1011 and the second slit 1012 are perpendicular to each other to form a first cross light path, and the third slit 2011 and the fourth slit 2012 are perpendicular to each other to form a second cross light path.

[0077] By forming a first cross-shaped optical path with the first slit 1011 and the second slit 1012, and forming a second cross-shaped optical path with the third slit 2011 and the fourth slit 2012, it is easier to observe and measure when the light emitted from the first cross-shaped optical path coincides with the light emitted from the second cross-shaped optical path, which is beneficial to improving the accuracy of debugging; it is also easier to process.

[0078] Preferred, such as Figure 3 and Figure 5 As shown, the spindle end assembly 1 includes a conical surface 701 with the first axis as the axis and a first plane 301 perpendicular to the first axis, the first plane 301 facing the cutter arm end assembly 2;

[0079] The first cross light path is disposed on the first plane 301, and the center line of the first cross light path coincides with the first axis.

[0080] By setting the conical surface 701, it is easy to fix the spindle end assembly 1 to the machining center spindle. The first cross light path is set on the first plane 301, which is beneficial to the machining of the first gap 1011 and the second gap 1012, and also helps to improve the machining accuracy of the first gap 1011 and the second gap 1012.

[0081] Preferably, the blade end assembly 2 includes a cylindrical surface 702 with the second axis as its axis and a second plane 302 perpendicular to the second axis, the second plane 302 being opposite to the first plane 301;

[0082] The second cross light path is disposed on the second plane 302, and the center line of the second cross light path coincides with the axis of the cylindrical surface 702.

[0083] By setting the cylindrical surface 702, it is easy to fix the tool arm end assembly 2 in the tool groove. The second cross light path is set on the second plane 302, which is beneficial to the processing of the third gap 2011 and the fourth gap 2012, and also helps to improve the processing accuracy of the third gap 2011 and the fourth gap 2012. The second plane 302 and the first plane 301 are relatively conducive to the overlap of the first cross light path and the second cross light path.

[0084] Preferred, such as Figure 1 As shown, the machining center tool change position adjustment device includes a first light source assembly 401 disposed on the spindle end assembly 1, and / or a second light source assembly 402 disposed on the tool arm end assembly 2.

[0085] When the first light source assembly 401 is only provided on the spindle end assembly 1, a first groove 7011 is provided at the center of the first crossbeam optical path of the spindle end assembly 1, such as Figure 4 As shown, the first groove 7011 is located on the side opposite to the first plane 301. The first light source assembly 401 is placed in the first groove 7011 and fixed in the first groove 7011 by the first plug 4011. The first light source assembly 401 emits cross light towards the second plane 302 through the first cross light path. The cross light completely enters the second cross light path, thus completing the XY axis adjustment.

[0086] When the second light source assembly 402 is only installed on the main arm end assembly 2, such as Figure 5 As shown, a second groove 7012 is provided at the center of the first crossbeam optical path of the spindle end assembly 1. The second groove 7012 is located on the side opposite to the second plane 302. The second light source assembly 402 is placed in the second groove 7012 and fixed in the second groove 7012 by the second plug 4021. The second light source assembly 402 emits crossbeams towards the first plane 301 through the second crossbeam optical path. The crossbeams completely enter the first crossbeam optical path, thus completing the XY axis adjustment.

[0087] When light source components are installed on both the spindle end assembly 1 and the tool arm end assembly 2, the XY axis adjustment is completed when the cross rays emitted from the first cross light path coincide with the cross rays emitted from the second cross light path.

[0088] A first cavity 801 is provided on the first plane 301 to accommodate a first power supply component 901 of the first light source assembly 401. The first power supply component 901 includes a power source and a switch. Similarly, a second cavity 802 is provided on the second plane 302 to accommodate a second power supply component 902 of the second light source assembly 402. The second power supply component 902 includes a second power source and a switch.

[0089] Preferred, such as Figure 5 As shown, a fifth slit perpendicular to the second cross light path is provided on the cylindrical surface 702, and the fifth slit constitutes a third light path 605; the third light path 605 is connected to the second cross light path.

[0090] When changing tools, a tool changer arm is required. The tool changer arm is equipped with a protruding slot. When changing tools, the light emitted from the third optical path 605 is located in the center of the protruding slot when the tool changer arm grabs the tool, ensuring the accurate positional relationship between the tool arm end assembly 2 and the tool changer arm.

[0091] By connecting the third optical path 605 and the second cross optical path, the depth of the second groove 7012 can reach the position of the third optical path 605. Thus, the light generated by the second light source assembly 402, which is set in the second groove 7012, can be emitted through the third optical path 605, reducing the number of light sources required.

[0092] Debugging, debugging, debugging, preferred, such as Figure 1 As shown, a first pin hole 501 is provided on the first plane 301, and a second pin hole 502 is provided on the second plane 302;

[0093] The cutter arm end assembly 2 is provided with a through hole 602 passing through the second plane 302, and the first plane 301 is provided with a threaded hole 601.

[0094] After the machining center is debugged by the spindle end assembly 1 and the tool arm end assembly 2, the spindle end assembly 1 and the tool arm end assembly 2 can be attached and fixed together by the first plane 301 and the second plane 302 to form a tool holder. The tool holder is consistent with the tool holder of the tool in the tool magazine of the machining center and can be used for tool changing action running, which improves the applicability of the debugging device for the tool changing position of the machining center.

[0095] After the machining center is debugged using the spindle end assembly 1 and the tool arm end assembly 2, disassemble the spindle end assembly 1 and the tool arm end assembly 2. Align the first plane 301 and the second parallel plane, and position the tool arm end assembly 2 and the spindle end assembly using the first pin hole 501 and the second pin hole 502. For better positioning, multiple first pin holes 501 and multiple second pin holes 502 can be provided. After positioning, the first crossbeam path and the second crossbeam path are perfectly aligned. Secure the spindle end assembly 1 and the tool arm end assembly 2 by passing screws through the through hole 602 and engaging with the threaded hole 601. This allows the tool arm end assembly 2 and the spindle end assembly 1 to form a single unit, capable of running and operating within the machining center.

[0096] On the other hand, the present invention also provides a machining center debugging method, for use with a machining center tool changer tail end position debugging device; the machining center debugging method includes the following steps:

[0097] Step 1: Move the tool magazine arm to the predetermined position and engage the tool arm end assembly 2 into the tool magazine arm's locking slot;

[0098] Step 2: Clamp the spindle end assembly 1 into the machining center spindle and move the machining center spindle above the tool arm end assembly 2;

[0099] Step 3: Adjust the locking screws of the tool magazine and use the level 3 to adjust the horizontal level of the tool arm end assembly 2;

[0100] Step 4: Turn on the first light source component 401 and the second light source component 402;

[0101] Step 5: Rotate the machining center spindle to adjust the parallelism of the light rays emitted from the first slit 1011 and the third slit 2011;

[0102] Step 6: Adjust the three-axis position of the machining center and the locking screw of the tool magazine so that the light emitted from the first slit 1011 coincides with the light emitted from the third slit 2011, and the light emitted from the second slit 1012 coincides with the light emitted from the fourth slit 2012; and center the bubble of the level 3.

[0103] Step 7: Measure the distance between spindle end assembly 1 and tool magazine end assembly and input it into the machining center.

[0104] Step 1: Move the tool magazine arm to the predetermined position and insert the tool arm end assembly 2 into the tool magazine arm's retaining groove; this step sets the tool arm end assembly 2 in the predetermined position, at which point the second cross light path on the tool arm end assembly 2 is basically in a vertical state.

[0105] Step Two: Clamp the spindle end assembly 1 into the machining center spindle and move the machining center spindle above the tool arm end assembly 2. When the machining center spindle is directly above the tool arm end assembly 2, a preliminary judgment can be made by observing the first and second crossbeam optical paths. In this step, the spindle end assembly 1 is set in a predetermined position. Since the machining center spindle is necessarily in a vertical state, the first crossbeam optical path on the spindle end assembly 1 is also vertically aligned, and the light rays emitted downwards from the first crossbeam optical path are also vertical.

[0106] Step 3: Adjust the locking screws of the tool magazine and adjust the level of the tool arm end assembly 2 using the level 3; this step is to perform preliminary leveling of the tool magazine using the level 3.

[0107] Step 4: Turn on the first light source component 401 and the second light source component 402; to prepare for the following steps.

[0108] Step 5: Rotate the machining center spindle to adjust the parallelism of the light emitted from the first slit 1011 and the light emitted from the third slit 2011. The purpose of this step is to first adjust the spindle end assembly 1 and the tool arm end assembly 2 to be parallel in one of the XY directions. At this time, the light emitted from the first slit 1011 and the light emitted from the third slit 2011 are parallel or coincident.

[0109] Step Six: Adjust the three-axis positions of the machining center and the locking screws of the tool magazine so that the light rays emitted from the first slit 1011 coincide with the light rays emitted from the third slit 2011, and the light rays emitted from the second slit 1012 coincide with the light rays emitted from the fourth slit 2012; and center the bubble of the level 3; adjust the three-axis positions of the machining center.

[0110] Step 7: Measure the distance between spindle end assembly 1 and tool magazine end assembly and input it into the machining center. In this step, after inputting the distance between spindle end assembly 1 and tool magazine end assembly into the machining center, subtracting this data completes the tool change point adjustment. The spatial relationship between spindle end assembly 1 and tool arm end assembly 2 after tool change point adjustment is not the same as the spatial relationship between the tool magazine arm and the spindle during actual tool change. Generally, after adjustment, the distance between the tool magazine arm and the spindle (this distance refers to the distance in the Z-axis direction) should be greater than the actual distance between the tool magazine arm and the spindle during tool change. This is because there needs to be observation space between spindle end assembly 1 and tool arm end assembly 2, and spindle end assembly 1 and tool arm end assembly 2 can be used for running and working when fixed together.
