Description

Technical Field

[0001] This invention relates to the field of torsion processing technology, and in particular to a workpiece torsion device. Background Technology

[0002] With the increasing demands for reliability, lifespan, and stability in information transmission from aerospace electronic equipment, there is an urgent need to improve the processing accuracy and performance consistency of key components through automated equipment or devices. Waveguides, as core components for microwave signal transmission, have their processing quality directly affecting the overall performance of the microwave system. Axial torsion is one of the key processes determining the performance of waveguides during processing. However, traditional torsion processes suffer from the following technical bottlenecks:

[0003] 1) Insufficient precision: The torsion angle is not accurately controlled, making it difficult to meet the tolerance requirements of high-precision waveguides;

[0004] 2) Poor process controllability: The lack of real-time angle monitoring and feedback mechanisms leads to low torsion consistency;

[0005] 3) Low efficiency: Relies on manual operation, limiting production efficiency;

[0006] 4) High risk of deformation: During the torsion process, the tube body is prone to deformation due to stress concentration or uneven force, which affects the product qualification rate.

[0007] The aforementioned problems, especially the low production efficiency, severely restrict the mass production of high-reliability and high-stability waveguides. Therefore, it is urgent to develop a waveguide axial torsion processing method and device to overcome the limitations of existing technology. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The purpose of this invention is to provide a workpiece torsion device to solve the problems existing in the prior art. By separating the upper die and the lower die of the pressure plate, it is convenient to place the second end of the workpiece in the clamping groove, which can improve the convenience of workpiece installation, improve processing efficiency, and facilitate mass production.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-4As shown, this invention provides a workpiece torsion device, mainly used for torsion processing of torsion workpieces such as waveguides. It includes a torsion module 5, a clamping module 8, and a worktable 2. The torsion module 5 includes a power structure and a torsion output structure connected to the power structure. The power structure mainly provides rotational power and can be an electric or manual rotation device. The torsion output structure is used to connect to the first end of the workpiece 10. The clamping module 8 includes a lower pressure plate mold 81 and an upper pressure plate mold 82. The upper pressure plate mold 82 is detachably connected to the lower pressure plate mold 81. Here, "detachable" means that the upper pressure plate mold 82 can rotate or translate with the lower pressure plate mold 81 to open the mold; that is, as long as mold opening is possible, it does not specifically refer to complete separation. The lower die 81 and the upper die 82 of the pressure plate combine to form a clamping groove 85 for accommodating the second end of the workpiece 10. When the upper die 82 of the pressure plate separates from the lower die 81, the clamping groove 85 is opened. At this time, the second end of the workpiece 10 can be inserted from top to bottom, or inserted laterally from one side to the other, thus providing a variety of convenient ways to clamp the second end of the workpiece 10. The torsion module 5 and the clamping module 8 are both mounted on the worktable 2. The worktable 2 provides support and limits, allowing the torsion output structure to rotate relative to the clamping module 8. Since the first end of the workpiece 10 is clamped by the torsion output structure and the second end of the workpiece 10 is clamped by the clamping module 8, the rotation of the torsion output structure can drive the first end of the workpiece 10 to twist relative to the second end.

[0039] This invention utilizes a torsion module 5 and a clamping module 8 to clamp both ends of a workpiece 10, respectively. The torsion output structure rotates relative to the clamping module 8, thereby causing the workpiece 10 to twist, thus enabling the torsion processing of the workpiece 10. Furthermore, the separable connection between the upper die 82 and the lower die 81 of the pressure plate facilitates the placement of the second end of the workpiece 10 into the clamping groove 85, where it is clamped and fixed using the clamping module 8. This improves the ease of installation of the workpiece 10, increases processing efficiency, and is beneficial for mass production.

[0040] In one embodiment, the upper die 82 is connected to the lower die 81 via a pivot 83, allowing the upper die 82 to rotate relative to the lower die 81 to open or close. A locking structure is provided at the end of the lower die 81 away from the pivot 83 to lock the upper die 82 onto the lower die 81. The locking structure can be a C-shaped clip, a U-shaped clip, a bolt, or the like. The upper die 82 has a first stepped shape, including a first low step 821 and a first high step 822. The lower die 81 has a second stepped shape, including a second low step 811 and a second high step 812. The first low step 821 engages with the second high step 812 (face contact or with a certain gap), and the first high step 822 engages with the second low step 811 (face contact or with a certain gap). This allows the first low step 821 and the second low step 811 to vertically compress the workpiece 10 after it is placed. There is a gap between the first high step 822 and the second high step 812. Thus, the first low step 821, the first high step 822, the second low step 811, and the second high step 812 can form a clamping groove 85. Through the combination of the first and second stepped shapes, more space is provided for the placement and installation of the second end of the workpiece 10 after the pressure plate mold 82 is opened. Furthermore, the side of the second high step 812 provides positioning, improving both the convenience and accuracy of clamping.

[0041] In one embodiment, the locking structure includes a boss 823 and a fixing pin 84. The boss 823 is disposed on the lower die 81 of the pressure plate and has a through hole. The end face of the upper die 82 of the pressure plate has a blind hole. After the upper die 82 of the pressure plate and the lower die 81 of the pressure plate are engaged, the through hole and the blind hole are axially aligned. At this time, the fixing pin 84 can be inserted through the through hole of the boss 823 and then inserted into the blind hole of the upper die 82 of the pressure plate, thereby locking the upper die 82 of the pressure plate and the lower die 81 of the pressure plate and ensuring the stability of the position of the workpiece 10 during the torsion process.

[0042] In one embodiment, a limiting fixture 7 is further included. The limiting fixture 7 is used to connect the first end of the workpiece 10 to the torsion module 5 and to connect the second end of the workpiece 10 to the clamping module 8. The limiting fixture 7 includes a first fixture 71 and a second fixture 72. The first fixture 71 is used to be installed on the torsion output structure and has a first limiting hole for the first end of the workpiece 10 to be inserted. The second fixture 72 is used to be installed on the clamping groove 85 and has a second limiting hole for the second end of the workpiece 10 to be inserted. The first limiting hole of the first fixture 71 and the second limiting hole of the second fixture 72 can be designed to different sizes according to the workpiece 10 to be installed, while the outer diameter of the first fixture 71 and the outer diameter of the second fixture 72 remain unchanged. By selecting different first fixtures 71 or second fixtures 72, different workpieces 10 can be clamped, further improving the convenience of application and the versatility of the device.

[0043] In one embodiment, the first tooling 71 is connected to a first baffle 711. When the first tooling 71 is installed on the torsion output structure, the first baffle 711 can be used to limit the insertion depth, allowing the first tooling 71 to be smoothly inserted into place, thus improving the ease and accuracy of installation. The second tooling 72 is connected to a second baffle 721. When the second tooling 72 is installed on the clamping module 8, the second baffle 721 can be used to limit the insertion depth, allowing the second tooling 72 to be smoothly inserted into place, thus improving the ease and accuracy of installation.

[0044] In one embodiment, a fixing base 6 is also included. The fixing base 6 includes a first base plate 62, a first vertical plate 61, and a mounting plate 63. The first base plate 62 is mounted on the workbench 2, for example, by means of bolts. The mounting plate 63 is connected to the first base plate 62. The first vertical plate 61 is connected to both the first base plate 62 and the mounting plate 63, thereby increasing the connection strength between the mounting plate 63 and the first base plate 62. One or more first vertical plates 61 can be provided. When multiple first vertical plates 61 are provided, they can be arranged in parallel. The first base plate 62, the first vertical plate 61, and the mounting plate 63 can be connected in pairs by welding. The mounting plate 63 is used to install and fix the torsion module 5.

[0045] In one embodiment, the power structure employs a servo motor 51, and the torsional output structure includes a reducer 52 and a rotary disk 53. The reducer 52 is mounted on a mounting plate 63, and its input end is connected to the servo motor 51. The servo motor 51 inputs power to the reducer 52, and its output end is connected to the rotary disk 53. After the reducer 52 reduces the speed and increases the torque, the power is transmitted to the rotary disk 53. Thus, driven by the servo motor 51, the rotary disk 53 can rotate, and the servo motor 51 precisely controls the rotation angle of the rotary disk 53. The rotary disk 53 is used to mount the first end of the workpiece 10, and it is provided with mounting holes to mount the workpiece 10 or the limiting fixture 7.

[0046] In one embodiment, an origin sensor is also included. The origin sensor is mounted on a sensor mounting plate 54, which is L-shaped. One arm of the L-shape is mounted on a mounting plate 63, and the other arm of the L-shape is used to mount the origin sensor. The origin sensor can detect the origin position of the rotary disk 53 and perform origin positioning before the torsion work begins, so that each torsion work has a uniform starting position and ensures the consistency of the torsion processing.

[0047] In one embodiment, a movable seat 4 is also included. The movable seat 4 includes a second base plate 42 and a second vertical plate 41. The second base plate 42 is mounted on the worktable 2. The mounting here can be a fixed connection or a movable connection. When movable, the relative positional relationship between the movable seat 4 and the fixed seat 6 can be adjusted, further improving the ease of installation of the workpiece 10. The lower die 81 of the pressure plate is connected to the second base plate 42, and the second vertical plate 41 is connected to both the second base plate 42 and the lower die 81 of the pressure plate. The second vertical plate 41 improves the connection strength between the lower die 81 of the pressure plate and the second base plate 42. One or more second vertical plates 41 can be provided. When multiple second vertical plates 41 are provided, they can be arranged in parallel. The lower die 81 of the pressure plate, the second base plate 42, and the second vertical plate 41 can be connected in pairs by welding.

[0048] In one embodiment, a slide rail 3 is also included. The slide rail 3 is mounted on the worktable 2. The extension direction of the slide rail 3 is parallel to the axis of the torsion module 5. The second base plate 42 of the movable seat 4 is slidably connected to the slide rail 3, so that the entire movable seat 4 can move on the slide rail 3 towards or away from the fixed seat 6 to adjust the clamping position and clamping method of the workpiece 10.

[0049] In one embodiment, a positioning seat 9 is also included. The positioning seat 9 includes a first connecting part and a second connecting part that are connected to each other. The first connecting part is connected to the second base plate 42, and the second connecting part is used to connect to different positioning positions of the worktable 2. That is, when the movable seat 4 moves to a set position on the slide rail 3, the second connecting part can be fixed on the worktable 2. At this time, the position of the movable seat 4 can be fixed to ensure that the workpiece 10 is stably clamped during the torsion processing.

[0050] In one embodiment, the system further includes an electrical box 1, with a workbench 2 mounted on top of the electrical box 1. The electrical box 1 has an upward-sloping operating surface, the height and orientation of which should facilitate operation. The operating surface is equipped with a touchscreen 11 and control buttons 12. The control buttons 12 include start, stop, forward or reverse movement, and may also include an emergency stop button. Additionally, the electrical box 1 may have internal installation space for mounting power supplies, controllers, and other equipment. Ventilation holes may be provided on the side of the electrical box 1.

[0051] The present invention provides the following operating method:

[0052] When clamping workpiece 10, the first fixture 71 is installed in the mounting hole of the rotary disk 53 and locked; workpiece 10 is installed on the second fixture 72, and the second fixture 72 is inserted into the first fixture 71 and slightly lifted. The upper die 82 of the pressure plate is lifted to expose the clamping groove 85. The clamping module 8 is pushed toward the second fixture 72 under the movement of the movable seat 4, so that the second fixture 72 is slowly pushed into the clamping groove 85. The upper die 82 of the pressure plate is lowered, and the fixing pin 84 is inserted to fix the second fixture 72.

[0053] The servo motor 51 of the torsion module 5 is activated. The servo motor 51 transmits rotational power to the rotary disk 53 through the reducer 52. The rotary disk 53 drives the first end of the workpiece 10 to perform torsion processing. The second end of the workpiece 10 is fixed and limited by the clamping module 8.

[0054] After the torsion processing is completed, pull out the fixing pin 84, lift the platen die 82, and while holding the workpiece 10 with your hand, push the movable seat 4 together with the clamping module 8 away from the fixed seat 6 until the workpiece 10 is removed from the first tooling 71. At this time, take out the second tooling 72 together with the processed workpiece 10, and then pull the workpiece 10 out of the second tooling 72.

[0055] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
