At this time, the first clamping block 211 and the second clamping block 221 are both rotatably arranged, and the first clamping block 211 and the second clamping block 221 are moved on the slideway 16 of the base 1 through the first sliding bracket 13 and the second sliding bracket 14 to leave space for the installation of the twist waveguide 10; the two ends of the twist waveguide 0 are clamped by the first clamping block 211 and the second clamping block 221 respectively; the first clamping block 211 and the second clamping block 221 can be chucks or claws; after the first clamping block 211 and the second clamping block 221 clamp the twist waveguide 10, the first clamping block 211 and the second clamping block 221 are rotated at a preset angle simultaneously or separately by holding the auxiliary twisting handle 24, and the rotation angle is determined according to the scale provided on the first twisting disk 213 or the second twisting disk 223; the auxiliary twisting handle 24 is detachably connected to the twisting disk.
[0030] For details, please see Figure 4An auxiliary support member 23 is also provided between the first movable platform 21 and the second movable platform 22; the auxiliary support member 23 is detachably provided on the slide 16 between the first movable platform 21 and the second movable platform 22; the auxiliary support member 23 is displaced based on the slide 16 through the third slider 19. The auxiliary support member 23 includes a support leg 231 and a support rod 232; the support leg 231 is hollow inside, and the support rod 232 is arranged inside the support leg 231; the support leg 231 and the support rod 232 are provided with a limit slot 234 at the corresponding position; the limit slot 234 is inclined; the support rod 232 adjusts the support height through the limit slot 234; the support leg 231 and the support rod 232 are fixed to each other by the cooperation of the limit slot 234 and the bolt; through the above adjustment setting, the height of the auxiliary support member 23 is adjustable, because the heights supported by the twist waveguide 10 of different sizes are also inconsistent, through the adjustment setting, the twist waveguide 10 of various sizes can be adaptively adjusted. A support plate 233 is provided on the top of the auxiliary support member 23, and the support plate 233 is arranged below the twist waveguide; the support plate 233 supports the twist waveguide 10 between the first moving platform 21 and the second moving platform 22. The auxiliary support 23 can be added or reduced according to the actual length of the twist waveguide 10; the auxiliary support 23 is used to increase the rigidity of the twist waveguide 10 during the torsion work, so that it is not easy to be damaged; when the actual length of the twist waveguide 10 is too short, the auxiliary support 23 can be used for support; the auxiliary support 23 can also adjust the height according to the caliber size of the twist waveguide 10, so that it can support the twist waveguide 10 in contact and avoid the twist waveguide 10 from being processed in the air. The maximum height of the auxiliary support 23 for adaptive adjustment does not exceed the height of the same axis of the first clamping block 211 and the second clamping block 221; this height is generally the axis height of the twist waveguide 10, so that it cannot interfere with the normal processing height of the twist waveguide 10. The support of the twist waveguide 10 by the support plate 233 of the auxiliary support 23 avoids the processing problems caused by insufficient rigidity due to the too long twist waveguide 10 during its processing; the auxiliary support 30 supports it to improve its processing stability.
[0031] Preferably, a limit member 17 is further provided on the base 1; the first sliding bracket 13 and the second sliding bracket 14 are respectively adjusted and fixed in position by different limit members 17; when the twist waveguide 10 is processed, the processing positions of the first movable table 21 and the second movable table 22 are first determined so that they cannot generate displacement during processing and interfere with normal processing; when the positions of the first movable table 21 and the second movable table 22 are determined, their positions are fixed by installing a plurality of the limit members 17.
[0032] Preferably, the first clamping block 211, the first twisting disk 213 and the first sliding bracket 13 are all provided with coaxial pin holes 214 at corresponding positions; when the pin 18 is arranged in the pin holes 214 on the first clamping block 211, the first twisting disk 213 and the first sliding bracket 13, the first clamping block 211 and the interior of the first moving platform 21 are fixedly assembled; when the first clamping block 211 and the second clamping block 221 need to rotate together to drive the twist waveguide 10 for processing, the pin 18 is not needed; however, when only one moving platform is needed for processing, it is necessary to restrict the clamping block of one of the moving platforms, because the clamping block itself can rotate, and may also rotate when subjected to a rotational force. If the first twisting disk 213 is not affected by the normal processing, it needs to be fixed; when fixing the first twisting disk 213, the position of the pin hole 214 is rotated to a position corresponding to the pin holes of the first clamping block 211 and the first sliding bracket 13, and the pin 18 is inserted into the pin hole 214 to fix the first twisting disk 213; a pin hole running through the three components is set at the same position of the first clamping block 211, the first twisting disk 213 and the first sliding bracket 13, and when the two clamping blocks do not need to rotate at the same time, the pin 18 is placed inside the pin hole, so that the first clamping block 211 and the first twisting disk 213 are fixed on the first sliding bracket 13, so that unnecessary rotation will not occur during processing.
[0033] Preferably, the first movable table 21 is movably arranged on the base 1 based on the first sliding bracket 13; when the second clamping block 221 rotates, the pushing cylinder 15 drives the first sliding bracket 13 to adaptively move in a direction away from the second movable table 22; when the twist waveguide 10 is twisted, the internal structure of the twist waveguide 10 will change, the rigidity of the twist waveguide 10 will be reduced, and it may bend and damaged; when one or two clamping blocks are performing twisting processing, an outward force is applied to the twist waveguide 10 on the movable table by pushing the cylinder 10, so that the twist waveguide 10 can always maintain a relatively stable state, so that its processing completion degree is higher.
[0034] Preferably, the first twisting disk 213 and the second twisting disk 223 are both provided with an auxiliary twisting handle 24; the auxiliary twisting handle 24 is arranged at the back of the first twisting disk 213 and the second twisting disk 223 near the periphery; the auxiliary twisting handle 24 is used to assist in twisting the first twisting disk 213 or the second twisting disk 223; the twist waveguide 10 can also be twisted by rotating the first twisting disk 213 and the second twisting disk 223.
[0035] Before the twist waveguide 10 to be processed is clamped to the first clamping block 211 and the second clamping block 221 of the twist waveguide 10, the inner body of the twist waveguide 10 can be filled with filling materials such as urea or alloy, and the alloy material is preferably an alloy of bismuth, tin and lead. After the twisted waveguide 10 is removed from the processing mechanism, the filler is taken out, which can effectively prevent the shape and wall thickness of the cross section of the twist waveguide 40 from changing after processing, and preventing flattening and wrinkling.
[0036] Working principle: when the length of the torsion waveguide 10 is normal, the second movable platform 21 and the second movable platform 22 limit their positions by the limiter 17 so that they cannot move; when the torsion waveguide 10 is twisted by rotating the auxiliary torsion handle 24, the first twisting disk 213 or the second twisting disk 223, the torsion angle is determined by the scale on the first twisting disk 213 or the second twisting disk 223, and at this time, the cylinder 15 is pushed to drag the first movable platform 21 to move adaptively to ensure that the torsion waveguide 10 will not be too long and the middle part will not sag due to gravity, resulting in an axial centerline deviation.
[0037] When the length of the twist waveguide 10 is long, the distance between the first movable table 21 and the second movable table 22 is adjusted by installing and disassembling the limit member 17 to leave enough distance for the twist waveguide 10, and an appropriate number of auxiliary support members 23 are provided under the twist waveguide 10 to support the twist waveguide 10; and then the twist waveguide is twisted.
[0038] Example 2
[0039] Second, see Figures 1 to 4 An embodiment of the utility model provides a processing device, including a twist waveguide processing mechanism as described in any of the above embodiments; the twist waveguide processing mechanism achieves precise positioning of the twist waveguide 10 and performs precise processing through the cooperation of the set pushing cylinder 15 and the first movable table 21, and the cooperation of the auxiliary support 23 and the twist waveguide 10.
[0040] Example 3
[0041] See also Figures 1 to 4The embodiment of the utility model provides a processing mechanism and a processing device for a twist waveguide. The processing mechanism and the processing device for a twist waveguide provided by the utility model have the following beneficial effects: enhancing the adaptability of processing the twist waveguide 10. The processing device drives the first movable table 21 to make adaptive movement when the twist waveguide 10 is twisted by pushing the cylinder 15. The force and processing stability of the twist waveguide can be adjusted according to actual processing requirements, so that it is not easy to bend and damage during twisting. The processing stability of the twist waveguide 10 is improved. The design of the auxiliary support member 23 enables the processing device to stably support the twist waveguide 10 during the processing, and the support height can be adjusted by the limit groove 234 and the bolt, so that the support height and adjustment of the twist waveguide 10 are more convenient; the accuracy of the twist waveguide 10 during long-distance processing is improved. It is set coaxially with the clamping block and fixed by the limit groove and the bolt, which can ensure that the twist waveguide 10 maintains a stable position and posture during the processing, thereby improving the processing accuracy.
[0042] In summary, the twist waveguide processing mechanism and its application in the processing device have the advantages of improving processing efficiency, processing accuracy and operating convenience, and are suitable for the twist waveguide processing field.
