DETAILED DESCRIPTION
[0041] The following is combined with Figure 2-14 This application is described in further detail.
[0042] The inventor of the present application discovered that when processing the three holes on the hook plate 9, the hook plate 9 needs to be disassembled and then fixed between processing the front hole and the side hole to adjust the orientation of the holes of the hook plate 9, which takes a long time and reduces the efficiency of hole processing of the hook plate 9. For this reason, the present application mainly adopts a rotating design of the tooling body 3 to adjust the orientation of the holes of the hook plate 9, so as to avoid disassembly and then fixing during the hole processing process, save the installation time of the hook plate 9, and improve the efficiency of hole processing of the hook plate 9.
[0043] The embodiment of the present application discloses a three-dimensional hole processing tool for a hook plate.
[0044] Example 1 Reference Figure 2 , Figure 3 The three-dimensional hole processing tooling of the hook plate includes a tooling body 3 and a drilling device 2 arranged on a machining center 1. The drilling device 2 is located above the tooling body 3. The drilling device 2 in this embodiment includes a spindle head 21, a tool magazine 22, and a tool changing manipulator 23. The spindle head 21 is arranged on a Z-axis moving frame, and the drilling tool is installed on the spindle head 21. The spindle head 21 is driven to rotate by a spindle motor, and the Z-axis moving frame drives the spindle head 21 to reciprocate along the Z axis. The tool magazine 22 stores multiple drilling tools, and the tool changing manipulator 23 is pneumatically driven to realize the rapid exchange of tools from the tool magazine 22 to the spindle, so as to realize the processing of holes with different hole diameters.
[0045] Reference Figure 2 , Figure 3 The machining center 1 is provided with an XY axis moving frame, and the XY axis moving frame is provided with a support table 11. The XY axis moving frame drives the support table 11 to slide along the X direction and the Y direction in the plane to adjust the horizontal position of the support table 11. The support table 11 is provided with two sets of rotating brackets 12 arranged at intervals. The tooling body 3 is rotatably connected to the two rotating brackets 12, and the rotating axis of the tooling body 3 is arranged along the Y direction. The middle part of the tooling body 3 is plate-shaped, so that installation stations 31 are formed on the two side walls of the tooling body 3 that are separated from each other. Each set of installation stations 31 is provided with a fixing component 4. Each set of fixing components 4 fixes a set of hook plates 9 on the tooling body 3, and exposes the front surface holes and side holes of the hook plates 9. The tooling body 3 is driven by the motor arranged on the support table 11 to rotate itself, adjust the two sets of hook plates 9 to exchange positions, and adjust the front surface holes and side holes of the hook plates 9 to face upwards. The spindle head 21 drives the drilling tool to process through holes on the front surface holes and side holes of the hook plates 9.
[0046] When processing the holes of the hook plates 9, first place one group of hook plates 9 on the installation station 31 of the tooling body 3, and then the fixing component 4 installs and fixes the group of hook plates 9 on the tooling body 3, and then the tooling body 3 is driven to flip 180°, and another group of hook plates 9 is installed and fixed to the installation station 31 of the tooling body 3 through the fixing component 4, completing the installation and fixation of the two groups of hook plates 9.
[0047] After the two groups of hook plates 9 are installed, the tooling body 3 is rotated so that the front of one group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the front of the hook plate 9. After the processing is completed, the tooling body 3 is rotated 90° so that the side of the hook plate 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the side of the hook plate 9. After the processing is completed, the tooling body 3 is rotated 90° again so that the front of another group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the front of this group of hook plates 9. After the processing is completed, the tooling body 3 is rotated 90° again so that the side of this group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the side of this group of hook plates 9, thereby completing the processing of the holes on the two groups of hook plates 9. During the processing of the front and side holes of the hook plate 9, there is no need to disassemble and fix the hook plate 9 in the middle, which saves the installation time of the hook plate 9, thereby improving the processing efficiency of the holes of the hook plate 9. At the same time, the tooling can process the holes on two groups of hook plates 9 at one time, further improving the processing efficiency of the holes on the hook plates 9.
[0048] Reference Figure 3 , Figure 4 In this embodiment, each group of fixing components 4 includes five pressing blocks 41, and the five pressing blocks 41 are arranged on the installation station 31 at intervals along the rotation axis of the tooling body 3. A fixed space 42 for the hook plate 9 to be placed is formed between two adjacent pressing blocks 41. A fixing portion 43 is provided at the end of the pressing block 41 opposite to the adjacent pressing block 41. The fixing portion 43 and the pressing block 41 are integrally formed. The pressing block 41 is connected to the tooling body 3 through a fixing member 5. The fixing member 5 in this embodiment includes a fixing bolt 51, which is passed through the pressing block 41 from top to bottom and is rotatably arranged with the pressing block 41. The end of the fixing bolt 51 cooperates with the threaded groove provided on the tooling body 3. The fixing bolt 51 presses and fixes the pressing block 41 on the tooling body 3 through the head, and the fixing portion 43 presses and fixes the hook plate 9 on the tooling body 3 at the same time.
[0049] When the hook plate 9 is fixedly installed on the tooling body 3, the hook plate 9 is placed in the fixing space 42, and the fixing bolt 51 fixes the pressing block 41 to the tooling body 3. At the same time, the pressing block 41 drives the fixing part 43 to press and fix the hook plate 9 on the tooling body 3, so that the hook plate 9 is installed and fixed on the tooling body 3.
[0050] Reference Figure 3 , Figure 4A stopper 6 corresponding to the fixed space 42 is provided on the tooling body 3, and the stopper 6 is arranged on the inner side of the fixed space 42. When the operator places the hook plate 9 in the fixed space 42, the stopper 6 can contact the hook plate 9. The contact between the stopper 6 and the hook plate 9 can be used to position the hook plate 9 in the fixed space 42, so that the installation position of the hook plate 9 is more accurate.
[0051] Reference Figure 5 , Figure 6 , a push rod 71 is provided on the side of the pressure block 41 opposite to the adjacent pressure block 41. The push rod 71 in this embodiment is only arranged on a pressure block 41 located on the right side of the two adjacent pressure blocks 41. There are two push rods 71, and the two push rods 71 are slidably inserted on the pressure block 41. The push rod 71 and the pressure block 41 are connected by a third spring 72. One end of the third spring 72 is fixedly connected to the push rod 71, and the other end is fixedly connected to the pressure block 41. Initially, the third spring 72 applies elastic force to the push rod 71 to extend out of the pressure block 41. When the hook plate 9 is placed in the fixed space 42, the push rod 71 pushes the hook plate 9 to abut against the relative pressure block 41, effectively avoiding the displacement of the hook plate 9 during the fixed installation process, and improving the accuracy of the fixed installation position of the hook plate 9.
[0052] Reference Figure 5 , Figure 6 The fixing part 43 is provided with a clearance hole. When the fixing part 43 is pressed against the hook plate 9, the clearance hole is aligned with the hole position on the hook plate 9, so that the drilling tool passes through the clearance hole to drill the hole position on the hook plate 9, thereby increasing the contact surface between the fixing part 43 and the hook plate 9 and improving the stability of the fixed installation of the hook plate 9. The tooling body 3 is provided with a placement hole. When the drilling tool is drilling the hook plate 9, the drilling tool passes through the hook plate 9 and is inserted into the placement hole, thereby reducing the wear between the tool and the tooling body 3.
[0053] The implementation principle of Example 1 is as follows: after the two groups of hook plates 9 are installed by the fixing bolts 51, the tooling body 3 is rotated so that the front of one group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the front of the hook plates 9. After the processing is completed, the tooling body 3 is rotated 90° so that the side of the hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the side of the hook plates 9. After the processing is completed, the tooling body 3 is rotated 90° again so that the front of another group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the front of the group of hook plates 9. After the processing is completed, the tooling body 3 is rotated 90° again so that the side of the group of hook plates 9 faces upward, and the spindle head 21 drives the drilling tool to process the holes on the side of the group of hook plates 9, thereby completing the processing of the holes on the two groups of hook plates 9. During the processing of the front holes and side holes of the hook plates 9, there is no need to disassemble and fix the hook plates 9 in the middle, which saves the installation time of the hook plates 9, thereby improving the processing efficiency of the holes of the hook plates 9.
[0054] Example 2 Reference Figure 7 , Figure 8 and Fig. 9 The difference between this embodiment and embodiment 1 is that a positioning seat 53 corresponding to the pressure block 41 is fixedly provided on each installation station 31, and the horizontal cross-section of the positioning seat 53 is the same as the horizontal cross-section of the pressure block 41. The fixed space 42 is surrounded by two adjacent positioning seats 53 and two pressure blocks 41. A rotating column 54 is fixedly provided at the bottom of the pressure block 41. A rotating hole 55 cooperating with the rotating column 54 is opened on the positioning seat 53. The rotating column 54 is inserted into the rotating hole 55 and is rotatably connected to the rotating hole 55.
[0055] Reference Fig. 9 , Fig.10 The fixing member 5 in this embodiment includes a fixing screw 521, which passes through the pressing block 41, the positioning seat 53, and the tooling body 3 in sequence. The fixing screw 521 is rotatably connected to the tooling body 3 and is threadedly connected to the pressing block 41. A driving cavity 81 is provided in the tooling body 3, and a driving shaft 84 arranged along the rotation axis of the tooling body 3 is provided in the driving cavity 81. The driving shaft 84 is rotatably connected to the tooling body 3, and a worm gear 82 is coaxially connected to the driving shaft 84. A worm 83 meshing with the worm gear 82 is provided in the driving cavity 81. The worm 83 is rotatably connected to the tooling body 3, and one end of the worm 83 passes through one side of the tooling body 3.
[0056] Reference Fig. 9 , Fig.10 The fixing screw 521 is inserted into one end of the tooling body 3 and extends into the driving cavity 81. The fixing screw 521 is connected to the driving shaft 84 at one end extending into the driving cavity 81 through a bevel gear structure, so that the driving shaft 84 drives a group of fixing screws 521 to rotate at the same time. When a group of hook plates 9 are fixedly installed, the hook plates 9 in a group are placed one by one in the fixed space 42, and then the operator rotates the driving shaft 84, and the driving shaft 84 drives a group of fixing screws 521 to rotate together through the bevel gear structure. The fixing screw 521 drives the pressing block 41 to press down and fix the hook plates 9, so that a group of hook plates 9 can be fixedly installed at the same time, thereby shortening the installation time of the hook plates 9 and improving the efficiency of the installation and fixation of the hook plates 9.
[0057] Reference Fig. 9 , Fig.10 and Fig.11The positioning seat 53 is provided with a clearance groove 522 which is coaxial with and connected to the rotating hole 55. The rotating column 54 is slidably plugged with an insert block 523. The insert block 523 is arranged along the radial direction of the rotating column 54. One end of the insert block 523 extends into the clearance groove 522. The insert block 523 is sleeved with a first spring 524 on the end extending from the rotating column 54. One end of the first spring 524 is fixedly connected to the rotating column 54, and the other end is fixedly connected to the insert block 523. The fixed screw 521 is provided with a driving groove 525. The driving groove 525 is arranged along the axial direction of the fixed screw 521. The length of the driving groove 525 is greater than the maximum distance difference of the pressing block 41 moving up and down. Initially, the elastic force applied by the first spring 524 to the insert block 523 toward the fixed screw 521 enables the insert block 523 to be inserted into the driving groove 525. When the insert block 523 is inserted into the driving groove 525, the fixed screw 521 can drive the pressing block 41 to rotate.
[0058] Reference Fig.12 , Fig.13 The two opposite side walls of the driving groove 525 are respectively a first guide surface 526 and a second guide surface 527. The distance between the second guide surface 527 and the first guide surface 526 gradually increases from the inside to the outside in the radial direction of the fixing screw 521, so that the insert block 523 can slide out of the driving groove 525 along the first guide surface 526 and the second guide surface 527. A positioning groove 528 is provided below the give way groove 522. The positioning groove 528 is an arc-shaped groove whose center is concentric with the fixing screw 521. The two ends of the positioning groove 528 are respectively a first positioning surface 5292 and a second positioning surface 5293. A positioning block 5291 inserted into the positioning groove 528 is fixedly provided on the rotating column 54. The positioning block 5291 is an arc-shaped block. The rotation angle of the positioning block 5291 from being in contact with the first positioning surface 5292 to being in contact with the second positioning surface 5293 is 90°. When the positioning block 5291 is in contact with the first positioning surface 5292, the fixing portion 43 completely slides out of the fixing space 42. When the positioning block 5291 is in contact with the second positioning surface 5293, the fixing portion 43 is located directly above the hook plate 9.
[0059] Reference Figure 7 , Fig.14A squeezing rod 561 is provided on the fixing part 43, and the squeezing rod 561 is located on the fixing part 43 on the right side of the two opposite fixing parts 43. The squeezing rod 561 is located on the side of the fixing part 43 away from the stopper 6, so that when the fixing part 43 is rotated into the fixing space 42, the squeezing rod 561 can push the hook plate 9 to abut against the stopper 6. The squeezing rod 561 is an L-shaped rod, one end of the squeezing rod 561 is inserted into the fixing part 43, and the other end is in a vertical state. The squeezing rod 561 is inserted between one end of the fixing part 43 and the fixing part 43 through a second spring 562. One end of the second spring 562 is fixedly connected to the squeezing rod 561, and the other end is fixedly connected to the fixing part 43. When the hook plate 9 is placed in the fixed space 42, the fixing screw 521 drives the fixing part 43 to rotate into the fixing space 42. The fixing part 43 pushes the extrusion rod 561 through the second spring 562 to squeeze the hook plate 9. The extrusion rod 561 pushes the hook plate 9 to abut against the stopper 6, thereby improving the contact stability between the hook plate 9 and the stopper 6.
[0060] The implementation principle of Example 2 is as follows: initially, the positioning block 5291 is in contact with the first positioning surface 5292, and the fixing portion 43 is completely rotated out of the fixing space 42, so that the fixing space 42 is opened, and the hook plate 9 is placed in the fixing space 42. After the hook plate 9 is placed in the fixing space 42, while the fixing screw 521 rotates, the first spring 524 pushes the insert block 523 to be inserted into the driving groove 525, so that the fixing screw 521 drives the pressing block 41 to rotate, and the rotating column 54 drives the positioning block 5291 to slide in the positioning groove 528. When the positioning block 5291 is in contact with the second positioning surface 5293, the fixing portion 43 is located directly above the hook plate 9. At this time, the fixing screw 521 is continuously rotated, and the insert block 523 slides out of the driving groove 525 along the second guide surface 527, so that the fixing screw 521 only drives the pressing block 41 to press down and fix the hook plate 9, so that the fixing portion 43 only fixes the hook plate 9 by moving downward, thereby improving the stability of the fixing portion 43 pressing and fixing the hook plate 9.
[0061] When the hook plate 9 is unloaded, the fixed screw 521 reverses to drive the pressing block 41 to release the squeeze state with the hook plate 9. As the fixed screw 521 rotates, when the driving groove 525 is aligned with the insert block 523, the first spring 524 pushes the insert block 523 to insert into the driving groove 525, and the fixed screw 521 drives the fixing portion 43 to rotate in the opposite direction, so that the fixing portion 43 rotates out of the fixing space 42. The rotating column 54 simultaneously drives the positioning block 5291 to slide toward the first positioning surface 5292. When the positioning block 525 is aligned with the insert block 523, the first spring 524 pushes the insert block 523 to insert into the driving groove 525. When 291 is in contact with the first positioning surface 5292, the fixing portion 43 rotates 90° and completely slides out of the fixing space 42. As the fixing screw 521 continues to rotate, the fixing portion 43 completely slides out of the fixing space 42. At this time, the insert block 523 slides out of the driving groove 525 along the first guide surface 526. The fixing screw 521 continues to rotate and only drives the pressing block 41 to lift, so that the fixing space 42 is opened, which is convenient for taking out the hook plate 9 from the fixing space 42, thereby improving the convenience of unloading the hook plate 9.
[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
