Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to an anti-deviation system and anti-deviation method for circular arc groove tapping of aluminum alloy profile. Background Art

[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in the industry. With the development and maturity of aluminum profile extrusion technology, more and more products use extruded aluminum profiles as product frames or support rods. Due to the needs of product structure, aluminum profiles often need to be designed with tapping fixing holes.

[0003] Some existing aluminum alloy profiles are still processed by manual tapping. The quality of manual tapping is greatly affected by human factors. The end of the tap is clamped by the manual tapping device, and the longer part of the tap body cannot be effectively supported. As a result, when the tap is subjected to rotation and downward pressure, the tap and the tapping mark hole are deviated, causing the tapped hole to be deviated and the thread of the tapped hole to be rotten, which affects the subsequent assembly and causes the tapped workpiece to be unqualified, thereby increasing the production cost. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when a rotational and downward pressure force is applied to the tap, a deviation occurs between the tap and the tapping mark hole, resulting in a deviation of the tapped hole and rotten threads of the tapped hole, and to propose an anti-deviation system and anti-deviation method for arc groove tapping of aluminum alloy profiles.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A system for preventing deviation of circular arc groove tapping of aluminum alloy profiles comprises a panel, a profile body and a tap, wherein the profile body is clamped in the panel, and further comprises: a moving plate arranged above the panel, the moving plate being provided with a linear groove and a first limiting sleeve slidably mounted in the linear groove, a first limiting plate penetrating the linear groove and fixedly mounted thereon, a compensating member being fixedly mounted on a side of the first limiting plate away from the first limiting sleeve; a limiting member, at least one second limiting sleeve being provided, and the second limiting sleeve close to a side of the moving plate being slidably mounted on an outer edge surface of the first limiting sleeve.

[0007] In order to reduce the deviation of the tapping direction of the tap, preferably, an annular clamp is fixedly installed below the first limiting plate, and a threaded groove is formed on the inner wall of the annular clamp.

[0008] In order to improve the accuracy of the tapping direction of the tap, further, a fastening bolt is fixedly installed above the first limiting plate, a nut is threadedly connected to the fastening bolt, and the bottom of the nut is against the moving plate.

[0009] In order to further reduce the deviation of the tapping direction of the tap, preferably, the limiting member further comprises: a first sliding groove arranged on the outer edge surface of the first limiting sleeve and a sliding block fitted therein, and the sliding block is fixedly connected to the inner wall of the second limiting sleeve.

[0010] In order to reset the second limiting sleeve, the second further includes: a first spring arranged in the first sliding groove, and two ends of the first spring are respectively fixedly connected to the slider and the bottom of the first sliding groove.

[0011] In order to clamp the two sides of the profile body, preferably, it also includes: two second sliding grooves symmetrically opened on the panel, guide blocks are slidably installed in the second sliding grooves, and first rubber pads are fixedly installed on the opposite surfaces of the guide blocks on both sides; a guide plate fixedly installed on the panel, the guide plate is provided with a guide groove and a guide pin that slides in the guide groove, and the guide pin is fixedly installed at one end outside the guide groove and the guide block; a guide rod slidably installed in the guide block, the upper end of the guide rod is fixedly installed on the moving plate, and the lower end of the guide rod passes through the second sliding groove and is fixedly installed with a second limit plate.

[0012] In order to reduce the extrusion of the tap along with the profile body during tapping, it further includes: a first airbag arranged in the second slide groove, the two ends of the first airbag are respectively fixedly connected to the guide block and the inner side wall of the second slide groove; an air outlet pipe is fixedly connected to the first airbag, and the end of the air outlet pipe away from the first airbag is connected to the compensation member.

[0013] In order to clamp the profile body in the Y-axis direction, preferably, it also includes: a clamping groove provided on the panel, a third sliding groove provided on the inner side wall of the clamping groove, and a first clamping plate slidingly cooperates in the third sliding groove; an adjusting bolt is rotatably installed in the panel, one end of the adjusting bolt passes through the panel to the clamping groove, and a sliding rail is rotatably installed on the end through which the adjusting bolt passes, and a second clamping plate is slidably installed on the sliding rail.

[0014] Preferably, a support plate is fixedly connected to the bottom of the guide block, and the support plate can be in contact with the bottom of the profile body; a sliding rod is slidably connected to the side wall of the support plate, and a pressure plate is fixedly connected to one end of the sliding rod close to the profile body, and a pressure sensor is provided on the side wall of the support plate, and a second spring is connected between the pressure plate and the pressure sensor; the pressure plate can be in contact with the side wall of the profile body.

[0015] A method for preventing the tapping of an arc groove of an aluminum alloy profile from deflecting, the operation steps are as follows:

[0016] Step 1: Clamp the profile body in the panel and clamp the profile body in the Y-axis direction. When tapping, the electric spindle drives the tap to rotate and enter the second limit sleeve. As the electric spindle is pressed down, the second limit sleeve shrinks step by step, and the tap passes through the moving plate;

[0017] Step 2: As the electric spindle is pressed, the guide rods on both sides drive the guide blocks on both sides to approach each other, clamping the profile body in the X-axis direction;

[0018] Step 3: After the first rubber pad contacts the profile body, push the profile body to the center;

[0019] Step 4: The compensating piece is simultaneously extended into the card slot of the profile body. As the guide block slides to squeeze the first airbag, the air in the first airbag is filled into the compensating piece, so that the compensating piece contacts the inner wall of the profile body, and the profile body is clamped in the Z-axis direction.

[0020] Step 5: The tap, the annular clamp and the tapped hole on the profile body are located on the same axis. When the tap rotates and descends, it first engages with the thread groove in the annular clamp and then enters the tapped hole on the profile body, thereby avoiding thread deviation.

[0021] Compared with the prior art, the present invention provides an anti-deviation system and anti-deviation method for arc groove tapping of aluminum alloy profiles, which has the following beneficial effects:

[0022] 1. The aluminum alloy profile circular arc groove tapping anti-deviation system, on the one hand, the pressing of the electric spindle causes the second limit sleeve to shrink step by step, and a suction cup adsorbed with the electric spindle is installed on the uppermost second limit sleeve. As the electric spindle is pressed down, the suction cup is fixed on the electric spindle to support the tap. As the second limit sleeve shrinks, the tap gradually exposes the first limit plate. Since the slider slides in the first slide groove, the first slide groove limits the shrinking direction of the second limit sleeve, reducing the left and right shaking of the tap, thereby improving the accuracy of tapping. On the other hand, the relative movement between the tap and the profile body is reduced, thereby improving the tapping effect.

[0023] 2. The aluminum alloy profile circular arc groove tapping anti-deviation system has a first limit plate whose cross section is consistent with that of the profile body. A circular hole concentric with the mounting hole is reserved at the center of the first limit plate for the movement of the tap. When tapping, the first limit plate covers the profile body, allowing the compensating part to extend into the slot in the profile body and have an interference fit with the slot to reduce deformation of the profile body.

[0024] 3. The aluminum alloy profile arc groove tapping anti-deviation system, when tapping, the tap rotates forward, first contacts the annular clamp and engages with the thread groove on the inner wall. The annular clamp with a harderness greater than the tap constrains the tap, reducing the deviation of the tap in the tapping hole. Even if the tap deviates in the tapping hole, the annular clamp can block the tap and will not deform due to extrusion, thereby improving safety and reliability.

[0025] 4. The aluminum alloy profile circular arc groove tapping anti-deviation system has a profile body clamped between a first clamping plate and a second clamping plate. The elastically connected first clamping plate and the second clamping plate apply a pre-tightening force to the profile body, thereby increasing the reliability and tightness of the clamping. At the same time, due to the clamping of the guide blocks on both sides, the profile body can be adjusted left and right on the slide rail, satisfying the tapping requirement that the tap, the tapping hole in the profile body and the annular clamp are all on the same axis.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Embodiment 1:

[0038] Reference Figure 1 - Figure 8 A system for preventing the tapping of circular arc grooves of aluminum alloy profiles from deflecting includes a panel 1 of rectangular structure, a profile body 2 and a tap 19. The profile body 2 is clamped in the panel 1 and has tapping holes for tapping and slots for heat dissipation. Support legs are fixedly installed at the four corners of the panel 1, and holes for screw connection are provided on the support legs, so that the device can be installed on a machine tool or installed with anti-slip feet and placed on a processing station to improve the practical performance of the device.

[0039] It also includes: a moving plate 3 arranged above the panel 1, a linear groove and a first limiting sleeve 4 slidably installed in the linear groove are arranged on the moving plate 3, a first limiting plate 5 is fixedly installed on the lower side of the first limiting sleeve 4 passing through the linear groove, and a compensation component 6 is fixedly installed on the side of the first limiting plate 5 away from the first limiting sleeve 4.

[0040] The cross-section of the first limiting plate 5 is consistent with that of the profile body 2. A circular hole concentric with the mounting hole is reserved at the center of the first limiting plate 5 for the movement of the tap 19. When tapping, the first limiting plate 5 covers the profile body 2, so that the compensation part 6 extends into the slot in the profile body 2 and has an interference fit with the slot to reduce the deformation of the profile body 2.

[0041] It should be noted that the compensating member 6 is a second airbag, which is always in close contact with the inside of the slot in the profile body 2 according to the change of the gas volume, supports the slot, and reduces the deformation of the tapped hole.

[0042] The limiting member is provided with at least one second limiting sleeve 7 , and the second limiting sleeve 7 close to the side of the moving plate 3 is slidably installed on the outer edge surface of the first limiting sleeve 4 .

[0043] The number of the second limiting sleeves 7 is 3-4. As the distance from the moving board 3 increases, the apertures of the second limiting sleeves 7 increase successively and slide on the outer edge surfaces of the adjacent second limiting sleeves 7 .

[0044] See also Figure 1 and Figure 2 and Figure 5 , the limiting parts in this scheme are further optimized.

[0045] The limiting member further includes: a first sliding groove 401 arranged on the outer edge surface of the first limiting sleeve 4 and a sliding block 8 fitted therein, wherein the sliding block 8 is fixedly connected to the inner wall of the second limiting sleeve 7 .

[0046] During tapping, the electric spindle drives the tap 19 to rotate, and the electric spindle first contacts the second limiting sleeve 7 at the top. A suction cup adsorbed to the electric spindle is installed on the second limiting sleeve 7 at the top. As the electric spindle is pressed down, the suction cup is fixed on the electric spindle, and the second limiting sleeve 7 shrinks step by step. Since the slider 8 slides in the first slide groove 401, the first slide groove 401 limits the shrinkage direction of the second limiting sleeve 7, reducing the left and right shaking of the tap 19, thereby improving the accuracy of tapping.

[0047] See also Figure 5 Furthermore, it also includes: a first spring 9 arranged in the first slide groove 401, and two ends of the first spring 9 are fixedly connected to the slider 8 and the bottom of the first slide groove 401 respectively.

[0048] During tapping, the tap 19 needs to be reversed to break chips, and the elastic potential energy of the first spring 9 causes the second limiting sleeve 7 to be reset step by step, which is convenient for secondary tapping.

[0049] See also Figure 2 An annular clamp 18 is fixedly installed below the first limiting plate 5, and the hardness of the annular clamp 18 is greater than the hardness of the tap 19. The inner wall of the annular clamp 18 is provided with a thread groove.

[0050] During tapping, the tap 19, the tapping hole in the profile body 2 and the annular clamp 18 are all on the same axis. When the tap 19 rotates forward for tapping, it first contacts the annular clamp 18 and engages with the thread groove on the inner wall. The annular clamp 18, which has a harderness than the tap 19, constrains the tap 19 and reduces the deviation of the tap 19 in the tapping hole. Even if the tap 19 deviates in the tapping hole, the annular clamp 18 can block the tap 19 and will not be deformed due to extrusion, thereby improving safety and reliability.

[0051] In general, before tapping, the profile body 2 is first clamped in the panel 1, so that the tap 19, the tapping hole in the profile body 2 and the annular clamp 18 are all on the same axis. When the profile body 2 is clamped, the pressure of the electric spindle causes the second limit sleeve 7 to shrink step by step. A suction cup adsorbed by the electric spindle is installed on the top second limit sleeve 7. As the electric spindle is pressed down, the suction cup is fixed on the electric spindle. As the second limit sleeve 7 shrinks, the tap 19 gradually exposes the first limit plate 5. Since the slider 8 slides in the first slide groove 401, the first slide groove 401 limits the shrinking direction of the second limit sleeve 7, reducing the left and right shaking of the tap 19, thereby improving the accuracy of tapping.

[0052] During tapping, the tap 19 rotates forward, first contacts the annular clamp 18 and engages with the thread groove on the inner wall. The annular clamp 18, which has a harderness than the tap 19, constrains the tap 19, reducing the deviation of the tap 19 in the tapped hole. Even if the tap 19 deviates in the tapped hole, the annular clamp 18 can block the tap 19 and will not be deformed due to extrusion, thereby improving safety and reliability.

[0053] Embodiment 2:

[0054] Reference Figure 1 - Figure 6 , which is basically the same as Example 1. On the basis of Example 1, the entire technical solution is further optimized, and an implementation plan for clamping the profile body 2 is specifically disclosed.

[0055] The aluminum alloy profile arc groove tapping anti-deviation system in this embodiment also includes: two second slide grooves 101 symmetrically opened on the panel 1, guide blocks 10 are slidably installed in the second slide grooves 101, and first rubber pads 15 are fixedly installed on the opposite surfaces of the guide blocks 10 on both sides; a guide plate 11 fixedly installed on the panel 1, the guide plate 11 is provided with a guide groove 1101 and a guide pin 12 that slides in the guide groove 1101, and one end of the guide pin 12 outside the guide groove 1101 is fixedly installed with the guide block 10; a guide rod 13 slidably installed in the guide block 10, the upper end of the guide rod 13 is fixedly installed with the moving plate 3, and the lower end of the guide rod 13 passes through the second slide groove 101 and is fixedly installed with a second limit plate 14.

[0056] The guide rods 13 on both sides are straight at the lower ends and close to each other at the upper ends. Under the pressure of the electric spindle, the moving plate 3 drives the guide rods 13 on both sides to slide down. The diagonal lines on the guide rods 13 squeeze the guide blocks 10 on both sides close to each other, so that the profile body 2 is clamped between the first rubber pads 15.

[0057] See also Figure 1 Furthermore, it also includes: a first airbag 16 arranged in the second slide groove 101, and the two ends of the first airbag 16 are fixedly connected to the guide block 10 and the inner side wall of the second slide groove 101 respectively; an air outlet pipe 17 is fixedly connected to the first airbag 16, and the end of the air outlet pipe 17 away from the first airbag 16 is connected to the compensation member 6.

[0058] When the guide blocks 10 are close to each other, the guide blocks 10 squeeze the first airbag 16 , so that the air in the first airbag 16 enters the second airbag through the air outlet pipe 17 , so that the second airbag expands and fills the slot in the profile body 2 .

[0059] It should be noted that a tension spring is fixedly installed in the first airbag 16. When the electric spindle releases the resistance to the moving plate 3, the tension spring resets, and the negative pressure in the first airbag 16 re-sucks the air in the second airbag, so that the second airbag releases the constraint on the profile body 2 and resets the guide block 10 at the same time.

[0060] Embodiment 3:

[0061] Reference Figure 1 - Figure 6 , which is basically the same as Example 2. On the basis of Example 2, the entire technical solution is further optimized, and an implementation plan for clamping the profile body 2 is specifically disclosed.

[0062] The aluminum alloy profile arc groove tapping anti-deviation system in this embodiment also includes: a clamping notch 102 opened on the panel 1, see Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 6 A third slide groove 103 is provided on the inner side wall of the clamping groove 102, and a first clamping plate 20 is slidably fitted in the third slide groove 103; an adjusting bolt 21 is rotatably installed in the panel 1, one end of the adjusting bolt 21 passes through the panel 1 to the clamping groove 102, and a slide rail 22 is rotatably installed on the end through which the adjusting bolt 21 passes, and a second clamping plate 23 is slidably installed on the slide rail 22, and a second rubber pad 24 is elastically connected to the first clamping plate 20 and the second clamping plate 23 on one side close to the profile body 2.

[0063] Place the profile body 2 in the clamping groove 102, rotate the adjusting bolt 21 to clamp the profile body 2 between the first clamping plate 20 and the second clamping plate 23, and the elastically connected first clamping plate 20 and the second clamping plate 23 apply a pre-tightening force to the profile body 2, thereby increasing the reliability and tightness of the clamping. At the same time, due to the clamping of the guide blocks 10 on both sides, the profile body 2 can be adjusted left and right on the slide rail 22 to meet the tapping requirement that the tap 19, the tapping hole in the profile body 2, and the annular clamp 18 are all on the same axis.

[0064] See also Figure 7 A fastening bolt 25 is fixedly installed above the first limiting plate 5 , and a nut 26 is threadedly connected to the fastening bolt 25 , and the bottom of the nut 26 abuts against the moving plate 3 .

[0065] In order to further reduce the deviation between the tap 19 and the profile body 2 during tapping, after the profile body 2 is fixed, the pressure on the moving plate 3 is released by loosening the nut 26, so that the first limit plate 5 can slide as a whole in the linear groove until it is located on the same axis as the tapping hole on the profile body 2. Then, the nut 26 is tightened to fix the first limit plate 5 as a whole, thereby improving the accuracy of tapping and further reducing the deviation.

[0066] See also Figure 8 A support plate 27 is fixedly connected to the bottom of the two guide blocks 10, and the support plate 27 can be in contact with the bottom of the profile body 2; a sliding rod 28 is slidably connected to the side wall of the support plate 27, and the number of the sliding rods 28 is two. A pressure plate 29 is fixedly connected to one end of the sliding rod 28 close to the profile body 2, and the pressure plate 29 slides on the support plate 27. A pressure sensor 30 is provided on the side wall of the support plate 27, and a second spring 31 is connected between the pressure plate 29 and the pressure sensor 30; the pressure plate 29 can be in contact with the side wall of the profile body 2.

[0067] When the guide rod 13 moves downward and pushes the guide block 10 to move toward the profile body 2, the support plate 27 is simultaneously driven to move so that the support plate 27 is in contact with the bottom of the profile body 2 to play a supporting role, thereby preventing the profile body 2 from moving downward under the action of the tap 19 during tapping, thereby improving the tapping stability.

[0068] When the support plate 27 is in contact with the bottom of the profile body 2, the pressure plates 29 on the support plates 27 on both sides of the profile body 2 are in contact with the side walls of the profile body 2, fixing the profile body 2 to the exact center. At the same time, the second spring 31 is compressed, and the force is applied to the pressure sensor 30. The pressure sensor 30 feeds back the pressure value. The pressure values ​​fed back by the pressure sensors 30 on both sides can be used to determine whether the profile body 2 is in the exact center.

[0069] When the pressure values ​​fed back by the pressure sensors 30 on both sides are the same, it means that the profile body 2 is in the center. When the pressure values ​​fed back by the pressure sensors 30 on both sides are different, it means that the profile body 2 is biased towards the side with a larger pressure value.

[0070] A method for preventing the tapping of an arc groove of an aluminum alloy profile from deflecting, the operation steps are as follows:

[0071] Step 1: Clamp the profile body 2 in the panel 1, clamp the profile body 2 in the Y-axis direction, and when tapping, the electric spindle drives the tap 19 to rotate and enter the second limiting sleeve 7. As the electric spindle is pressed down, the second limiting sleeve 7 shrinks step by step, and the tap 19 passes through the moving plate 3;

[0072] Step 2: As the electric spindle is pressed, the guide rods 13 on both sides drive the guide blocks 10 on both sides to approach each other, clamping the profile body 2 in the X-axis direction;

[0073] Step 3: After the first rubber pad 15 contacts the profile body 2, it pushes the profile body 2 to the center;

[0074] Step 4: The compensating member 6 is simultaneously extended into the slot of the profile body 2. As the guide block 10 slides and squeezes the first airbag 16, the air in the first airbag 16 is filled into the compensating member 6, so that the compensating member 6 contacts the inner wall of the profile body 2, and the profile body 2 is clamped in the Z-axis direction.

[0075] Step 5: The tap 19, the annular clamp 18 and the tapped hole on the profile body 2 are located on the same axis. When the tap 19 rotates and descends, it first engages with the thread groove in the annular clamp 18 and then enters the tapped hole on the profile body 2, thereby avoiding thread deviation.

[0076] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

7. The aluminum alloy profile circular arc groove tapping anti-deviation system according to claim 6, characterized in that: A support plate (27) is fixedly connected to the bottom of the guide block (10), and the support plate (27) can be attached to the bottom of the profile body (2); The side wall of the support plate (27) is slidably connected to a sliding rod (28); one end of the sliding rod (28) close to the profile body (2) is fixedly connected to a pressure plate (29); a pressure sensor (30) is provided on the side wall of the support plate (27); and a second spring (31) is connected between the pressure plate (29) and the pressure sensor (30); The pressure plate (29) can be in contact with the side wall of the profile body (2).

8. A method for preventing the tapping of an arc groove of an aluminum alloy profile from deflecting, using the system for preventing the tapping of an arc groove of an aluminum alloy profile from deflecting according to any one of claims 1 to 7, characterized in that: The steps are as follows: Step 1: Clamp the profile body (2) in the panel (1), and clamp the profile body (2) in the Y-axis direction. When tapping, the electric spindle drives the tap (19) to rotate and enter the second limiting sleeve (7). As the electric spindle is pressed downward, the second limiting sleeve (7) shrinks step by step, and the tap (19) passes through the moving plate (3); Step 2: As the electric spindle is pressed, the guide rods (13) on both sides drive the guide blocks (10) on both sides to approach each other, thereby clamping the profile body (2) in the X-axis direction; Step 3: After the first rubber pad (15) contacts the profile body (2), it pushes the profile body (2) to the center; Step 4: The compensating member (6) is simultaneously extended into the slot of the profile body (2). As the guide block (10) slides and squeezes the first airbag (16), the air in the first airbag (16) is filled into the compensating member (6), so that the compensating member (6) contacts the inner wall of the profile body (2), thereby clamping the profile body (2) in the Z-axis direction. Step 5: The tap (19), the annular clamp (18) and the tapped hole on the profile body (2) are located on the same axis. When the tap (19) rotates and descends, it first engages with the thread groove in the annular clamp (18) and then enters the tapped hole on the profile body (2), thereby avoiding thread deviation.
