Description

Technical Field

[0001] The invention relates to the field of mechanical processing, and in particular to a tool for processing special-shaped components. Background Art

The top ears 111 and the bottom ears 112 are both provided with ear holes. There is no reference at the bottom of the frame 11 and it cannot be placed stably on the workbench. A bent beam 12 is arranged on one side of the frame. In order to meet the use requirements, it is necessary to process the surface of the frame and both sides of the bent beam respectively. It is difficult for traditional tooling to stably clamp the special-shaped component. At the same time, it is necessary to flip the workpiece during the processing to process the other side of the workpiece. On the one hand, the workpiece is heavy and the flipping process is more laborious. On the other hand, the processing of both sides of the special-shaped component requires two sets of tooling for clamping, and the tooling cost investment is relatively large.

[0003] Therefore, a technical solution is currently needed to solve the technical problems of difficult stable clamping, laborious turning process and large tooling cost during the processing of special-shaped components with a suspended curved beam on one side. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problems in the prior art of special-shaped components with a suspended curved beam on one side, such as difficulty in stable clamping, laborious turning over and large tooling cost during processing, and to provide a special-shaped component processing tool.

[0005] The present invention provides a tool for processing special-shaped components, comprising a base, on which a first limiting mechanism, a second limiting mechanism, a third limiting mechanism, a first supporting mechanism and a second supporting mechanism are arranged, the second limiting mechanism and the third limiting mechanism are respectively arranged on both sides of the first limiting mechanism, the first supporting mechanism is arranged on one side of the second limiting mechanism, and the second supporting mechanism is arranged on one side of the third limiting mechanism; The first limiting mechanism comprises two first fixing seats arranged opposite to each other, wherein the first fixing seats are detachably provided with a first limiting shaft; The second limiting mechanism comprises a second fixing seat, on which a second limiting shaft is detachably provided; The third limiting mechanism comprises a first supporting frame, on which a third fixing seat is arranged, and on which a third limiting shaft is detachably arranged; The first supporting mechanism comprises a first supporting block, the first supporting block is used to be arranged on the processing table, and the top surface of the first supporting block is arranged to be a concave shape adapted to the shape of the curved beam of the special-shaped component; The second supporting mechanism comprises a second supporting frame, on which a second supporting block is arranged, and the top surface of the second supporting block is configured as a convex surface that matches the shape of the curved beam of the special-shaped component.

[0006] The present invention discloses a tool for processing special-shaped components. When in use, the top ear piece of the special-shaped component is placed between the two first fixing seats, and the first limiting shafts are respectively passed through the two first fixing seats, and the two first limiting shafts respectively fix the two top ear pieces. The bottom ear piece at the lower end of the special-shaped component is located on one side of the third fixing seat, and the third limiting shaft is passed through the third fixing seat, and the third limiting shaft fixes the two bottom ear pieces of the special-shaped component. The curved beam at the side of the special-shaped component is supported by the second supporting block at the top of the second supporting frame. After the processing of this side of the special-shaped component is completed, the special-shaped component is rotated around the two first limiting shafts so that the bottom ear piece of the special-shaped component The plate is located on one side of the second fixed seat, and the second limiting shaft is passed through the second fixed seat. The second limiting shaft fixes the two bottom ear plates at the lower end of the special-shaped component, and the curved beam on the side of the special-shaped component is supported by the first supporting block on the processing table, thereby realizing the clamping of the special-shaped component in two states, which not only ensures the stable clamping of the special-shaped component, but also the two clamping states share the first limiting mechanism, integrating the two sets of tooling into one set of tooling, reducing the investment in tooling costs, and when the special-shaped component is turned over, the operator can lift the bottom end of the special-shaped component to rotate the special-shaped component around the first limiting shaft to turn it over, which is easy to operate and more labor-saving.

[0007] Preferably, at least one end surface of the first limiting shaft is detachably provided with a flange, and the flange is used to press the top ear piece of the special-shaped component against the side surface of the first fixing seat.

[0008] After the first limiting shaft penetrates the first fixing seat and the top ear of the special-shaped component, the flange is connected to the end face of the first limiting shaft by bolts, thereby pressing the top ear against the inside of the first fixing seat, thereby fixing the top ear along the limiting shaft direction.

[0009] Preferably, an extension platform is provided on one side of the base, and the second supporting frame is arranged on the extension platform.

[0010] Since the curved beam is located at the side of the frame, after the frame is installed on the base, the curved beam will extend out of one side of the base. By arranging an extension platform at one side of the base, an installation position is provided for the second support frame.

[0011] Preferably, it further comprises a plurality of cushion blocks, wherein the plurality of cushion blocks are arranged on the bottom surface of the base.

[0012] After the special-shaped component is turned over, the bent beam on one side of the frame will extend downward. Therefore, the height difference between the top surface of the base and the first support block is required to meet the height of the bent beam extending downward. If the height of the base is directly increased, it will cause problems of high tooling consumables and heavy weight. By setting a pad between the base and the processing table to increase the height of the top surface of the base, after the special-shaped component is clamped on the base, the bent beam on one side of it can be exactly located on the concave surface of the first support block, and at the same time the problem of excessive base height can be avoided.

[0013] Preferably, the second support block is provided with a plurality of clamping mechanisms, and the plurality of clamping mechanisms are arranged along the length direction of the second support block.

[0014] By arranging a clamping mechanism on the second support block, the position of the bent beam on the second support block is stabilized, the shaking of the bent beam during processing is reduced, and the processing quality of the bent beam is improved.

[0015] Preferably, the clamping mechanism includes two limit plates, and the two limit plates are arranged on both sides of the second support block. A stop block is provided at one end of the limit plate toward the second support block, and an extension block is provided at the other end of the limit plate toward the second support block. The extension block is connected to the bottom surface of the second support block through a height adjustment screw. The second support block is provided with a threaded through hole, and a support screw is arranged in the threaded through hole. The support screw passes through the threaded through hole and abuts against the bent beam of the special-shaped component.

[0016] After the special-shaped component is installed on the base, the bent beam falls onto the second support block. The support screws are adjusted according to the position of the bent beam so that the support screws abut against the outer side of the bottom edge of the bent beam. The height adjustment screws are then rotated to make the block abut against the inner side of the bottom edge of the bent beam, thereby forming a vertical limit for the bent beam and reducing the up and down shaking of the bent beam during processing.

[0017] Preferably, the clamping mechanism further includes two connecting screws, the connecting screws are arranged in one-to-one correspondence with the limiting plates, the limiting plates are provided with waist-shaped holes, and the connecting screws pass through the waist-shaped holes to be connected to the side surface of the second support block.

[0018] The length direction of the waist-shaped hole is consistent with the moving direction of the limit plate during the adjustment process. After the position of the limit plate is adjusted, the limit plate can be pressed against the side of the second support block by connecting screws, so that the limit plate can be installed more firmly on the second support block, so that the limit plate can provide a stronger limiting effect for the bent beam.

[0019] Preferably, the limiting plate is provided with a limiting screw hole, the limiting screw hole is equipped with a limiting screw, and the limiting screw passes through the limiting screw to abut against the curved beam of the special-shaped component.

[0020] The two limit screws pass through the two limit plates respectively and abut against the two side surfaces of the bent beam respectively, forming a lateral limit for the bent beam and reducing the left and right shaking of the bent beam during processing.

[0021] Preferably, it also includes a clamping mechanism, which includes a third support frame and a clamping bolt. A mounting plate is provided on the top of the third support frame, a pressure plate is provided on the mounting plate, and an avoidance groove is provided on the pressure plate. The clamping bolt passes through the avoidance groove and is connected to the mounting plate.

[0022] By setting a clamping mechanism, a local area of ​​the special-shaped component is clamped, thereby improving the overall stability of the special-shaped component and reducing the shaking of the frame part of the special-shaped component during processing.

[0023] Preferably, it further includes a third supporting mechanism, which includes a fourth supporting frame, the top of the fourth supporting frame is provided with a supporting plate adapted to the local shape of the special-shaped component, and the bottom of the fourth supporting frame is detachably connected to the base by fastening bolts.

[0024] By providing a third supporting mechanism, a local area of ​​the special-shaped component is supported, the load-bearing capacity of the special-shaped component is improved, and the deformation of the frame part of the special-shaped component during the processing is reduced.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a tooling for processing special-shaped components, which can realize stable clamping of special-shaped components and reduce shaking during the processing of special-shaped components by setting a first limiting mechanism to fix the top ear piece of the special-shaped component, fixing the bottom ear piece of the special-shaped component by a second limiting mechanism or a third limiting mechanism, and supporting the side curved beam of the special-shaped component by a first supporting block or a second supporting block; 2. The present invention provides a tooling for processing special-shaped components, which integrates the components involved in two clamping states of the special-shaped component into a set of tooling by arranging a first limiting mechanism on the base to fix the top ear piece of the special-shaped component, and arranging corresponding structures for fixing the bottom ear piece of the special-shaped component and supporting the side curved beam of the special-shaped component on both sides of the first limiting mechanism, thereby reducing the investment of tooling cost; 3. The present invention provides a tooling for processing special-shaped components. By arranging a first limit mechanism shared by two clamping states on the base, when the special-shaped component is turned over, the operator can lift the bottom end of the special-shaped component to rotate the special-shaped component around the first limit axis to turn over, which is easy to operate and more labor-saving; 4. The present invention provides a tooling for processing special-shaped components. Two clamping states share one set of tooling. Compared with the split tooling design, the integral tooling design is easier to obtain better positioning accuracy under the same difficulty coefficient alignment operation method. For example, the position accuracy from the large shaft hole to the tail end is 0.03 according to the process requirement error; the split tooling is aligned according to the 0.03 error, and the alignment difficulty coefficient is 1; the integral tooling is also aligned to 0.03 according to the difficulty coefficient 1. Because the tooling length is twice that of the split tooling, the accuracy from the large shaft hole to the tail end becomes 0.015.

[0032] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig. 9 As shown, a tooling for processing special-shaped components comprises a base 2, on which a first limiting mechanism 3, a second limiting mechanism 4, a third limiting mechanism 5, a first supporting mechanism 6 and a second supporting mechanism 7 are arranged, wherein the second limiting mechanism 4 and the third limiting mechanism 5 are respectively arranged on both sides of the first limiting mechanism 3, the first supporting mechanism 6 is arranged on one side of the second limiting mechanism 4, and the second supporting mechanism 7 is arranged on one side of the third limiting mechanism 5; The first limiting mechanism 3 comprises two first fixing seats 31 arranged opposite to each other, and a first limiting shaft 32 is detachably provided on the first fixing seats 31; The second limiting mechanism 4 comprises a second fixing seat 41 on which a second limiting shaft 42 is detachably provided; The third limiting mechanism 5 comprises a first supporting frame 51, on which a third fixing seat 52 is arranged, and on which a third limiting shaft 53 is detachably arranged; The first supporting mechanism 6 comprises a first supporting block, the first supporting block is used to be arranged on the processing table, and the top surface of the first supporting block is arranged to be a concave shape adapted to the shape of the curved beam 12 of the special-shaped component 1; The second supporting mechanism 7 comprises a second supporting frame 71 , on which a second supporting block 72 is disposed. The top surface of the second supporting block 72 is configured to be a convex surface that matches the shape of the curved beam 12 of the special-shaped component 1 .

[0033] When in use, the top ear piece 111 of the special-shaped component 1 is placed between the two first fixing seats 31, and the first limiting shafts 32 are respectively passed through the two first fixing seats 31, and the two first limiting shafts 32 fix the two top ear pieces 111 respectively. The bottom ear piece 112 at the lower end of the special-shaped component 1 is located on one side of the third fixing seat 52, and the third limiting shaft 53 is passed through the third fixing seat 52, and the third limiting shaft 53 fixes the two bottom ear pieces 112 of the special-shaped component 1. The curved beam 12 on the side of the special-shaped component 1 is supported by the second supporting block 72 at the top of the second supporting frame 71. After the processing of this side of the special-shaped component 1 is completed, the special-shaped component 1 is rotated around the two first limiting shafts 32 so that the bottom of the special-shaped component 1 The second limit axis 42 is provided on the second fixing seat 41 to fix the two bottom ear pieces 112 at the lower end of the special-shaped component 1. The curved beam 12 on the side of the special-shaped component 1 is supported by the first supporting block on the processing table, thereby realizing the clamping of the special-shaped component 1 in two states, which not only ensures the stable clamping of the special-shaped component 1, but also the two clamping states share the first limit mechanism 3, integrating the two sets of tooling into one set of tooling, reducing the investment in tooling costs, and when the special-shaped component 1 is turned over, the operator can lift the bottom end of the special-shaped component 1 to rotate the special-shaped component 1 around the first limit axis 32 to turn it over, which is easy to operate and more labor-saving.

[0034] The first limiting mechanism 3: In the first limiting mechanism 3, a flange 321 is detachably provided on the end face of one of the first limiting shafts 32, and the flange 321 is used to press the top ear 111 of the special-shaped component 1 onto the side of the first fixing seat 31. After the first limiting shaft 32 penetrates the first fixing seat 31 and the top ear 111 of the special-shaped component 1, the flange 321 is connected to the end face of the first limiting shaft 32 by bolts 322, so that the top ear 111 is pressed against the inner side of the first fixing seat 31, thereby realizing the fixation of the top ear 111 along the direction of the limiting axis.

[0035] Base 2: The base is made of HT250, which is easier to ensure the durability of precision than steel welded structural parts, is more resistant to impact and vibration, and has more stable precision in long-term use. Since the bent beam 12 is located on the side of the frame 11, after the frame 11 is installed on the base 2, the bent beam 12 will extend out of one side of the base 2. By setting an extension platform 21 on one side of the base 2, an installation position is provided for the second support frame 71; after the special-shaped component 1 is turned over, the bent beam 12 on one side of the frame 11 will extend downward, so the height difference between the top surface of the base 2 and the first support block is required to meet the height of the bent beam 12 extending downward. If the height of the base 2 is directly increased, it will cause problems such as high tooling consumables and heavy weight. By setting a pad 22 between the base 2 and the processing table to increase the height of the top surface of the base 2, after the special-shaped component 1 is clamped on the base 2, the bent beam 12 on one side can be just located on the concave surface of the first support block, and at the same time, the problem of excessive height of the base 2 can be avoided; a plurality of lightening grooves are set on the bottom surface of the base 2, which can greatly reduce the weight of the base 2.

[0036] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the second support block 72 is provided with a plurality of clamping mechanisms 10 , and the plurality of clamping mechanisms 10 are arranged along the length direction of the second support block 72 .

[0037] In this embodiment, by providing a clamping mechanism 10 on the second support block 72 , the position of the bent beam 12 on the second support block 72 is stabilized, the shaking of the bent beam 12 during processing is reduced, and the processing quality of the bent beam 12 is improved.

[0038] The clamping mechanism 10 includes two limit plates 101, which are arranged on both sides of the second support block 72. A stopper 1011 is arranged at one end of the limit plate 101 toward the second support block 72. An extension block 1012 is arranged at the other end of the limit plate 101 toward the second support block 72. The extension block 1012 is connected to the bottom surface of the second support block 72 through a height adjustment screw 1013. The second support block 72 is provided with a threaded through hole 721, and a support screw is arranged in the threaded through hole 721. Nail 722, the supporting screw 722 passes through the threaded through hole 721 and abuts against the bent beam 12 of the special-shaped component 1. After the special-shaped component 1 is installed on the base 2, the bent beam 12 falls above the second supporting block 72. The supporting screw 722 is adjusted according to the position of the bent beam 12 so that the supporting screw 722 abuts against the outer side of the bottom edge of the bent beam 12, and then the height adjustment screw 1013 is rotated to make the stop block 1011 abut against the inner side of the bottom edge of the bent beam 12, thereby forming a vertical limit for the bent beam 12 and reducing the up and down shaking of the bent beam 12 during processing.

[0039] Furthermore, the clamping mechanism 10 also includes two connecting screws 1015, and the connecting screws 1015 are arranged in a one-to-one correspondence with the limiting plate 101. The limiting plate 101 is provided with a waist-shaped hole, and the connecting screws 1015 pass through the waist-shaped hole and are connected to the side of the second support block 72. The length direction of the waist-shaped hole is consistent with the moving direction of the limiting plate 101 during the adjustment process. After the position of the limiting plate 101 is adjusted, the limiting plate 101 can be pressed against the side of the second support block 72 by the connecting screws 1015, so that the limiting plate 101 is installed more firmly on the second support block 72, so that the limiting plate 101 can provide a stronger limiting effect for the bending beam 12.

[0040] Furthermore, the limiting plate 101 is provided with a limiting screw hole, and the limiting screw hole is equipped with a limiting screw 1014. The limiting screw 1014 passes through the limiting screw 1014 and abuts against the bent beam 12 of the special-shaped component 1. The two limiting screws 1014 pass through the two limiting plates 101 respectively, and abut against the two side surfaces of the bent beam 12 respectively, forming a lateral limit for the bent beam 12, thereby reducing the left and right shaking of the bent beam 12 during processing.

[0041] Through the above-mentioned clamping mechanism 10 and the height adjustment screw 1013 on the second support block 72, the vertical and lateral limiting of the bent beam 12 of the special-shaped component 1 on the second support block 72 is achieved, so that the bent beam 12 can be fixed in a free state, avoiding deformation of the bent beam 12 during the clamping process, and improving the processing quality of the bent beam 12 of the special-shaped component 1.

[0042] Similarly, when processing the other side of the special-shaped component 1, the bent beam 12 falls onto the first support block, and the first support block can also fix the bent beam 12 through a clamping mechanism 10 with the same or similar structure, so that the bent beam 12 can be clamped in a free state.

[0043] Example 3 like Figure 2 , Figure 7 and Fig. 9 As shown, this embodiment is different from Embodiment 1 in that it further includes an auxiliary clamping mechanism, and the auxiliary clamping mechanism includes a clamping mechanism 8 and a third supporting mechanism 9 .

[0044] In this embodiment, since the size of the special-shaped component 1 is large and the stability of the special-shaped component 1 is far away from the first limiting mechanism 3, the second limiting mechanism 4 or the third limiting mechanism 5, it is difficult to ensure the stability of the special-shaped component 1. By setting a clamping mechanism 8 to clamp the local position of the special-shaped component 1, and by setting a third supporting mechanism 9 to support the local position of the special-shaped component 1, the overall stability and strength of the special-shaped component 1 are improved.

[0045] The clamping mechanism 8 includes a third support frame 81 and a clamping bolt 322. A mounting plate 82 is provided on the top of the third support frame 81. A pressing plate 83 is provided on the mounting plate 82. The pressing plate 83 is provided with an avoidance groove 831. The clamping bolt 322 passes through the avoidance groove 831 and is connected to the mounting plate 82. The clamping mechanism 8 clamps a local area of ​​the special-shaped component 1 to improve the overall stability of the special-shaped component 1 and reduce the shaking of the frame 11 of the special-shaped component 1 during processing.

[0046] The third supporting mechanism 9 includes a fourth supporting frame 91, the top of the fourth supporting frame 91 is provided with a supporting plate 92 adapted to the local shape of the special-shaped component 1, the bottom of the fourth supporting frame 91 is detachably connected to the base 2 by a fastening bolt 322, and the third supporting mechanism 9 supports the local area of ​​the special-shaped component 1, improves the bearing capacity of the special-shaped component 1, and reduces the deformation of the frame 11 of the special-shaped component 1 during the processing.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
