Description

Technical Field

[0001] The invention relates to the technical field of gear shaping cutter installation, in particular to a clamping device for a composite slotting tool used for metal cutting. Background Art

[0002] Slotting is a cutting method that achieves metal cutting through reciprocating movement. It is often used to process grooves, gears, etc., and when processing multi-gears such as duplex gears and triplex gears, the center of the teeth or tooth grooves of one gear section on the same part must be symmetrical with the center of the teeth or tooth grooves of another gear section. Therefore, during the processing process, when replacing the tool, it is necessary to adjust the circumferential direction angle of the tool to make the circumferential direction angle of the new tool consistent with the circumferential direction angle of the old tool, so that the centers of the multiple teeth or tooth grooves of the multi-gear are symmetrical after the tool is replaced. With the existing adjustment means, the newly installed gear shaping cutter has a slow adjustment speed when adjusting the circumferential direction angle, and requires high operator skills, which seriously affects the effective utilization rate of the gear shaping machine.

[0003] In order to improve the replacement speed of the tool, the utility model with application number CN202420809741.3 provides a gear shaping cutter installation and correction device, which is connected to the tool through a permanent magnet, and the radial direction of the gear shaping cutter body is limited by the calibration bar inside the device, and then the installation of the gear shaping cutter body can be fully corrected through the contact between the micrometer and the calibration bar, thereby ensuring that the circumferential direction angle of the newly installed tool is consistent with the original tool, thereby ensuring the processing accuracy of the gear. However, when adjusting the circumferential direction angle of the tool, it is necessary to move the gear shaping machine workbench back and forth along the X direction to check the distance bias between the micrometer and the calibration bar to determine whether the circumferential direction angle of the newly installed tool is adjusted in place. Therefore, the adjustment process is still relatively complicated.

[0004] Therefore, in order to improve the replacement speed of slotting tools during multi-gear machining, a clamping device for a composite slotting tool for metal cutting is proposed. Summary of the Invention

[0005] The object of the present invention is to provide a clamping device for a composite slotting tool for metal cutting. In order to increase the speed of slotting tool replacement during multi-gear machining, the present invention uses a first positioning rod and a second positioning rod to position the workbench and the tool respectively, so that the tool can be positioned during the clamping process, which can not only ensure the installation accuracy of the tool, but also improve the efficiency of tool replacement.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A clamping device for a composite slotting tool for metal cutting includes a mounting seat, a fastening bolt, and a positioning bolt. The mounting seat is provided with a first threaded hole and a second threaded hole, the first threaded hole and the second threaded hole are coaxially arranged, the fastening bolt is threadedly connected to the first threaded hole, the positioning bolt is threadedly connected to the second threaded hole, the positioning bolt is sleeved inside the fastening bolt, the mounting seat is provided with a positioning piece, the positioning piece is provided with a first positioning rod and a second positioning rod, and a pressure sensor is provided between the first positioning rod and the positioning piece, and when the positioning piece is squeezed by the positioning bolt, it pushes the first positioning rod and the second positioning rod to move in the vertical direction.

[0008] By setting the positioning rod 1 to fit with the workbench, the circumferential direction angle of the spindle can be quickly judged by the value displayed by the pressure sensor, and then by setting the positioning rod 2, the circumferential direction angle of the tool is always consistent with the circumferential direction angle of the spindle. Therefore, when changing the tool, the circumferential direction angle of the tool can be quickly adjusted. By setting the positioning part and the positioning bolt, after clamping the tool, the positioning rod 1 and the positioning rod 2 can be moved in the vertical direction, so as to move away from the top of the tool, so as not to interfere with the tool's slotting operation. After removing the positioning bolt, the positioning part loses the extrusion positioning block of the positioning bolt and can be reset. At this time, to reinstall the tool, it is only necessary to make the positioning rod 1 fit with the workbench and make the tool contact with the positioning rod 2 to ensure that the circumferential direction angle of the tool is the same as the circumferential direction angle of the tool previously processed. For this reason, this method is simpler and more convenient, effectively improving the effective utilization rate of the gear shaping machine, and this method has a simple structure and low cost. The squeezing and tightening bolts by the positioning bolts can play an anti-loosening role, preventing the tool from loosening during processing, thereby ensuring the stability of the gear shaping machine during operation.

[0009] Preferably, the positioning member includes a slide groove 1, a slide groove 2, a slider 1, and a slider 2. The mounting seat is provided with a slide groove 1 and a slide groove 2. Slide groove 1 and slide groove 2 are respectively slidably installed inside the slide groove 1 and the slide groove 2. Slide groove 1 and slide groove 2 are elastically connected to the mounting seat. Slide groove 1 and slide groove 2 extend into the interior of threaded hole 2. The number of positioning rods 1 is 2, and they are symmetrically slidably installed on slider 1. An extrusion spring is connected between the positioning rod 1 and slider 1. The pressure sensor is arranged between the extrusion spring and the mounting seat. The positioning rod 2 is an L-shaped rod, and the two ends of the positioning rod are connected to slider 2 through adjusting bolts.

[0010] By cooperating with the workbench through the two positioning rods, when the pressure displayed by the pressure sensor is consistent, the circumferential angle of the spindle is always consistent with that before the tool is changed, and by fitting the positioning rod with the tool, the circumferential angle of the tool and the spindle can be made consistent, thereby ensuring that the circumferential angle is consistent after the tool is replaced. During the process, if the pressure of the pressure sensor is inconsistent, it is only necessary to rotate the spindle to observe the change in the pressure value of the pressure sensor until the numbers displayed by the pressure sensor are consistent, then stop the spindle rotation, thereby ensuring the rapid installation of the tool, thereby effectively improving the installation speed.

[0011] Preferably, an annular groove is provided on the fastening bolt, a rubber pad is provided inside the annular groove, and the rubber pad protrudes from the annular groove by 2-4 mm.

[0012] By setting the rubber pad, the friction between the fastening bolt and the tool can be increased, and then when the fastening bolt is rotated, the tool can be driven to rotate, so that the tool automatically fits into the positioning rod 2, so that when the staff locks the tool, the staff does not need to hold the tool by hand to ensure the positioning of the tool, thereby avoiding the problem that the staff holding the tool by hand affects the operation and causes the tool to scratch the staff. After being squeezed, the rubber pad can increase the locking force of the fastening bolt, thereby improving the clamping effect on the tool and ensuring the stability of the gear shaping machine during operation.

[0013] Preferably, a conical positioning groove is provided below the first and second slide grooves along the radial direction of the mounting seat, and a positioning plate that cooperates with the positioning groove is provided on the second slide block.

[0014] The setting of the positioning groove can position the positioning rod 1 and the positioning rod 2 by cooperating with the positioning plate and the positioning groove when the slider 1 and the slider 2 move to the bottom of the slide groove 1 or the slide groove 2, thereby avoiding the position offset of the positioning rod 1 and the positioning rod 2 due to the sliding gap of the slider, which leads to the circumferential angular offset after the tool is replaced, thereby causing the problem of processing error. The setting of the positioning groove can limit the swing of the positioning rod 1 and the positioning rod 2 due to the rotational gap between the slider 1 and the slider 2 after the positioning plate or the positioning groove is worn, so that the angle can be readjusted after wear and the device can continue to be used, thereby effectively improving the service life of the clamping device.

[0015] Preferably, the first slide groove and the second slide groove are inclined upward along the axis of the rotating shaft, and the first slide groove and the second slide groove are located on one side of the outer edge of the rotating shaft and respectively cooperate with the first slide block and the second slide block.

[0016] By setting the slide groove one and the slide groove two to be inclined upward along the axis of the rotating shaft, when the positioning bolt is rotated, the slider one and the slider two can be pushed to move obliquely upward, so that the positioning rod one and the positioning rod two are away from the cutting edge of the processing tool. At this time, the normal operation of the tool will not be interfered with, and the moving distance is small, thereby reducing the slot length of the slide groove one and the slide groove two, thereby ensuring the strength of the mounting seat. The slide groove one and the slide groove two are located on one side of the outer edge of the rotating shaft and cooperate with the slider one and the slider two respectively. When the slider one and the slider two slide, the slider one and the slider two are respectively sunk into the slide groove one and the slide groove two, thereby preventing iron chips generated by processing from entering the positioning groove and affecting the positioning accuracy of the positioning rod one and the positioning rod two, thereby ensuring the processing accuracy of the gear shaping machine.

[0017] Preferably, the width of the second slide groove is 2-3 mm larger than the width of the second slider, the side of the positioning groove facing the rotation direction of the fastening bolt is the positioning surface, the inner wall of the second slide groove is elastically connected with an extrusion block, and the elastic force direction of the extrusion block on the second slider is toward the positioning surface.

[0018] By setting the width of the second slide groove to be 2-3mm larger than the width of the second slider, the second slider can move along the radial direction of the second slide groove, and the side of the positioning groove facing the rotation direction of the fastening bolt is the positioning surface, and the inclination direction of the inclined section is parallel to the positioning surface. Therefore, the extrusion block can squeeze the second slider to move toward the side of the positioning surface, and then make the positioning rod one move obliquely upward along the second positioning surface, so that the positioning rod two is separated from the tool, thereby avoiding the problem of damaging the tool when the positioning rod two moves upward.

[0019] Preferably, a sealing airbag is provided on the slider 1 and the slider 2, a protective airbag is provided on the slider 1 at the sliding portion of the positioning rod 1, a channel is provided inside the slider 1, and the sealing airbag is connected to the protective airbag through the channel.

[0020] By setting up the sealing airbag, the entry of cutting fluid can be avoided, thereby preventing impurities in the cutting fluid from entering the positioning groove and affecting the positioning effect of positioning rod one and positioning rod two. The setting of the protective airbag, when the sealing airbag is squeezed, expands the protective airbag to seal the sliding part of positioning rod one, thereby preventing the liquid from contacting the pressure sensor and affecting the detection accuracy of the pressure sensor. The setting of the sealing airbag can reduce the vibration of slider one and slider two caused by the movement of the main shaft during the processing, thereby effectively improving the service life of the parts. The expansion of the protective airbag can also reduce the vibration of positioning rod one, thereby ensuring the positioning accuracy of positioning rod one.

[0021] Preferably, the head of the adjusting bolt is located at the top, and the rotation direction of the adjusting bolt is opposite to the rotation direction of the fastening bolt.

[0022] The direction of rotation of the adjusting bolt is opposite to that of the fastening bolt. When the positioning rod 2 is first installed, the adjusting bolt can be rotated to the side of the tool, so that the positioning rod 2 can rotate when installed, which makes adjustment more convenient. The head of the adjusting bolt is located at the top, so when the adjusting bolt is rotated, the wrench always presses the positioning rod 2 downward, so as to avoid the positioning plate being disengaged from the positioning groove due to the upward thrust of the slider 2 when tightening the adjusting bolt, thereby affecting the positioning accuracy of the positioning rod 2, thereby ensuring the processing accuracy of the gear shaping machine.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention improves the fixing effect of the tool by setting the positioning bolt, prevents the tool from loosening during the processing, and ensures the stability of the gear shaping machine during operation. After removing the positioning bolt, the installed tool can be quickly adjusted in the circumferential direction, thereby effectively increasing the tool replacement speed, ensuring the effective utilization rate of the gear shaping machine, and improving production efficiency.

[0025] 2. The two positioning rods 1 and 2 are pushed upward obliquely by the positioning bolts, so that the positioning rods 1 and 2 are away from the top of the cutting tool. At this time, the normal operation of the tool will not be interfered with, and the moving distance is small, which reduces the slot length of the slide 1 and the slide 2, thereby ensuring the strength of the mounting seat. The tool positioning and tool processing can be carried out by disassembling and assembling the positioning bolts, thereby improving the convenience of the use process.

[0026] 3. The setting of the positioning groove can position the positioning rod 1 and the positioning rod 2 by cooperating with the positioning plate and the positioning groove when the slider 1 and the slider 2 move to the bottom of the slide groove 1 or the slide groove 2, thereby avoiding the position offset of the positioning rod 1 and the positioning rod 2 due to the existence of the sliding gap of the slider, resulting in inconsistent circumferential angles of the new and old tools and causing processing errors. The positioning groove is conical in shape, which can still limit the swing of the positioning rod 1 and the positioning rod 2 due to the rotation gap between the slider 1 and the slider 2 after the positioning plate or the positioning groove is worn. The angle can be readjusted after wear and the device can continue to be used, thereby effectively improving the service life of the clamping device. BRIEF DESCRIPTION OF THE DRAWINGS

The slider 1 66 and the slider 2 67 are elastically connected to the mounting seat 1 through an extrusion spring 68. The slider 1 66 and the slider 2 67 extend into the interior of the threaded hole 2 5. Two positioning rods 1 61 are symmetrically slidably installed on the slider 2 67. An extrusion spring 68 is connected between the positioning rod 1 61 and the slider 1 66. A pressure sensor 63 is provided between the extrusion spring 68 and the mounting seat 1. The positioning rod 2 62 is an L-shaped rod. The end of the positioning rod 2 62 is connected to the slider 2 67 through an adjusting bolt 69. The adjusting bolt 69 is left Twist and lock; a ring groove 7 is provided on the fastening bolt 2; a conical positioning groove 9 is provided below the slide 1 64 and the slide 2 65 along the radial direction of the mounting seat 1, and a positioning plate 10 is provided on the slider 2 67 to cooperate with the positioning groove 9; the slide 1 64 and the slide 2 65 are inclined upward along the axis of the shaft, and the slide 1 64 and the slide 2 65 are located on one side of the outer edge of the shaft and cooperate with the slider 1 66 and the slider 2 67 respectively. A sealing airbag 12 is provided on the slider 1 66 and the slider 2 67, and a protective airbag 13 is provided on the slider 1 66 at the sliding part of the positioning rod 1 61. A channel 14 is provided inside the first 66, through which the sealing airbag 12 is connected to the protective airbag 13; the width of the second slide groove 65 is 3 mm greater than the width of the second slider 67, and the side of the positioning groove 9 facing the rotation direction of the fastening bolt 2 is the positioning surface 91. The inner wall of the second slide groove 65 is elastically connected with an extrusion block 11, and the direction of the elastic force of the extrusion block 11 on the second slider 67 is toward the positioning surface 91; a rubber pad 8 is provided inside the annular groove 7, and the rubber pad 8 protrudes 74 mm from the annular groove. The head of the adjusting bolt 69 is located at the top, and the rotation direction of the adjusting bolt 69 is opposite to that of the fastening bolt 2.

[0038] The specific implementation method is: please refer to Figure 1 and Figures 3 to 8, during the initial processing, after the tool 15 is adjusted, the rotation angle of the spindle is recorded, and the angle is set to θ1. When the processing of the first workpiece is completed, the positioning rod 1 61 is rotated to the side of the workbench 16, and the positioning bolt 3 is removed. At this time, the slider 1 66 and the slider 2 67 can move obliquely downward under the action of the spring force, and then the adjusting nut is rotated to remove the positioning rod 2 62. After the removal is completed, the spindle is moved along the Z-axis direction, and then the workbench 16 is moved along the X-axis and Y-axis directions, so that the workbench 16 squeezes the two positioning rods 1 61. At this time, the positioning rod 1 61 compresses the extrusion spring 68. At this time, the pressure sensor 63 generates a value. Observe the number displayed by the pressure sensor 63. If the displayed numbers are consistent, there is no need to rotate the spindle. At this time, the rotation angle of the spindle can be recorded again. If the displayed numbers are inconsistent, rotate the spindle so that the spindle rotates to the side of the pressure sensor 63 that displays a larger value. The rotation direction is as follows Figure 4 S1 in the middle indicates that at this time, the display numbers of the two pressure sensors 63 increase at the same time, and the sensor with a larger display value increases at a smaller rate. When the display numbers of the two pressure sensors 63 are consistent, the rotation of the main shaft is stopped and the rotation angle of the shaft is recorded. The angle is set to θ2. At this time, the positioning rod 2 62 is installed by adjusting the bolt 69. During installation, the positioning rod 2 62 swings along the S1 direction to fit the cutting surface of the tool 15. After the positioning is completed, the main shaft is rotated, and the rotation angle is the difference between θ1 and θ2. At this time, the circumferential direction of the gear cutting can be restored to an accurate state. At this time, the positioning screw can be installed, and the positioning screw is used to squeeze the slider 1 66 and the slider 2 67 to move obliquely upward to prevent the positioning rod 1 61 and the positioning rod 2 62 from interfering with the cutting operation of the tool 15; when the tool 15 is damaged, the positioning bolt 3 and the fastening bolt 2 are rotated along the S1 direction to release the clamping of the tool 15. At this time, the tool 15 can be removed. After the positioning bolt 3 is removed, the slider 1 66 and the slider The second 67 slides downward, and the newly installed tool 15 is placed on the mounting seat 1, and the positioning rod 2 62 is located inside the tooth groove of the tool 15. At this time, the tool 15 is manually rotated to make the tool 15 fit with the positioning rod 2 62. At this time, the fastening bolt 2 is rotated along the S2 direction to lock the tool 15. During the locking process, the rubber pad 8 drives the tool 15 to squeeze the positioning rod 2 62, so that the problem of the positioning rod 2 62 not being able to fit with the tool 15 is not likely to occur. After locking the tool 15, the positioning rod 1 61 is rotated to one side of the workbench 16, the spindle is moved along the Z-axis direction, and then the workbench 16 is moved along the X-axis and Y-axis directions so that the workbench 16 squeezes the two positioning rods 1 61. Continue the above adjustment method until the displayed values ​​of the two pressure sensors 63 are equal. At this time, the spindle is rotated, and the rotation angle is the difference between θ1 and θ2. The newly replaced tool 15 can be consistent with the circumferential direction angle of the old tool 15, thereby ensuring the processing accuracy of the gear shaping machine.

[0039] See also Figure 1 、 Figure 5In the process of the downward movement of the slider 1 66 and the slider 2 67, the positioning plate 10 is completely fitted with the positioning groove 9, thereby positioning the positioning rod 1 61 and the positioning rod 2 62, thereby avoiding the position offset of the positioning rod 1 61 and the positioning rod 2 62 due to the existence of the sliding gap of the slider, thereby causing the circumferential angle offset after the tool 15 is replaced, thereby causing the problem of processing error. The setting of the positioning groove 9 can still limit the swing of the positioning rod 1 61 and the positioning rod 2 62 due to the rotation gap between the slider 1 66 and the slider 2 67 after the positioning plate 10 or the positioning groove 9 is worn, so that the angle can be readjusted after wear and the device can continue to be used, thereby effectively improving the service life of the clamping device.

[0040] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 、 Figure 8 When slider 1 66 and slider 2 67 move obliquely upward, slider 1 66 and slider 2 67 cooperate with slide groove 1 64 and slide groove 2 65 respectively, and fit into the side walls of slide groove 1 64 and slide groove 2 65 through the sealing airbag 12, thereby preventing impurities in the cutting liquid and iron filings from entering the positioning groove 9 and affecting the positioning effect of positioning rod 1 61 and positioning rod 2 62. When the sealing airbag 12 is squeezed, the internal gas enters the protective airbag 13 along the airway, thereby sealing the sliding gap of positioning rod 1 61 and preventing the liquid from contacting the pressure sensor 63 and affecting the detection accuracy of the pressure sensor 63. The setting of the sealing airbag 12 can reduce the vibration of slider 1 66 and slider 2 67 caused by the movement of the main shaft during the processing, thereby effectively improving the service life of the parts. The expansion of the protective airbag 13 can also reduce the vibration of the positioning rod 1 61, thereby ensuring the positioning accuracy of the positioning rod 1 61.

[0041] See also Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 The rotation direction of the adjusting bolt 69 is opposite to that of the fastening bolt 2. When the positioning rod 2 62 is first installed, the adjusting bolt 69 can be rotated to make the adjusting bolt 69 swing toward the side of the tool 15, so that the positioning rod 2 62 can be rotated when installed, and the adjustment is more convenient. The head of the adjusting bolt 69 is located at the top, and the wrench can always press the positioning rod 2 62 downward when the adjusting bolt 69 is rotated, so as to avoid the positioning plate 10 being disengaged from the positioning groove 9 due to the upward thrust of the slider 2 67 when the adjusting bolt 69 is locked, thereby ensuring the processing accuracy of the gear shaping machine.
