Description

Technical Field

[0001] The utility model relates to the technical field of waveguide cylinder production and processing equipment, in particular to a processing tooling for thin-wall waveguide cylinders. Background Art

[0002] In the entire electromagnetic spectrum, microwaves are between radio frequency radio waves and infrared rays, and are the radio waves with the highest frequency. Its bandwidth is 1000 times wider than the sum of all ordinary radio wave bands. At microwave frequencies, a system that transports electromagnetic waves from one place to another in the system without energy radiation is called a waveguide system, or simply a waveguide. The guided electromagnetic wave is called a guided wave. The basic requirements for a waveguide are: low energy loss, high transmission efficiency, large power capacity, wide operating frequency band, small and uniform size. A regular waveguide, as a commonly used microwave component, can meet the above requirements. A waveguide is usually composed of a hollow metal tube with different cross-sectional shapes filled with a certain medium. The surface of the medium is generally a continuous single surface, which restricts and guides the electromagnetic waves therein. A waveguide cylinder is a conduction tool for transmitting ultra-high frequency electromagnetic waves. The electromagnetic waves can be transmitted to the destination with a certain loss through the waveguide cylinder. Through the action of high-frequency electromagnetic waves, the heating effect can be achieved. Electromagnetic heating is a new type of green metallurgy method and is widely used in modern industry and life.

[0003] During the forming process of the waveguide cylinder, a clamping tooling is needed to fix it to position the processing surface. However, existing processing equipment usually uses the method of clamping and limiting at both ends for alignment to position the processing position of the waveguide cylinder. Such processing clamping equipment cannot effectively maintain the outer contour of the thin-wall waveguide cylinder and is extremely prone to uncontrollable deformation under external pressure during the processing, resulting in processing misalignment and affecting the processing quality. In addition, the existing clamping structures usually can only clamp workpieces with fixed dimensions, are not convenient for adjusting according to the actual size changes of the workpieces, and cannot adaptively perform adjustable clamping and positioning on workpieces with multiple dimensions while effectively maintaining the shape contour of the workpieces.

Preferably, the main sleeve 41 is connected to the surface of the steering positioning assembly 2 facing the transverse movement positioning assembly 3 in a manner without relative movement. Preferably, a threaded rod 42 threadedly connected thereto is inserted into the main sleeve 41. Further preferably, the threaded rod 42 penetrates through the steering positioning assembly 2. Preferably, an internally threaded translation sleeve 43 is threadedly sleeved on the rod body of the threaded rod 42 away from the main sleeve 41.

Preferably, a triangular inner support rib 46 parallel to the axis of the threaded rod 42 and adjustably abutted against the corner area of the inner wall surface of the waveguide tube blank is provided on the deflecting two-link 45.

Preferably, a square rotating rod head 47 is also threadedly sleeved on the end of the threaded rod 42 away from the main sleeve 41. Specifically, the square rotating rod head 47 is adjustably inserted into the transverse movement positioning assembly 3 to define the relative working position between the adjustable inner support assembly 4 and the transverse movement positioning assembly 3. The threaded rod 42 provided in the present application can drive the distance between the internally threaded translation sleeve 43 threadedly sleeved on its rod body and the main sleeve 41 by rotation, so that the included angle between the deflecting two-link 45 and the threaded rod 42 changes, and the linear distance between the hinged position of the two rod bodies of the deflecting two-link 45 and the threaded rod 42 changes. Furthermore, a plurality of circumferentially spaced deflecting two-links 45 cooperate to construct an inner support structure with an adjustable radial contour size, so as to adaptively abut the triangular inner support rib 46 against the corner area of the inner wall surface of the waveguide tube blank. The length of the triangular inner support rib 46 is shorter than the length of the waveguide tube blank. The present application effectively maintains the outer contour of the waveguide tube blank through the corner surface abutting support of a plurality of circumferentially spaced triangular inner support ribs 46, so that the waveguide tube blank can be restricted by multi-directional inner support abutting forces and maintain the straight state of the tube wall, avoiding deformation of the tube wall under pressure, thereby ensuring the stability and accuracy of milling processing and improving the precision and quality of processing.

[0038] The working principle of the present application is as follows:

[0039] The waveguide tube blank is sleeved on the adjustable inner support assembly 4, and one end of it is abutted against the anti-slip cushion layer 215 of the first main board 21. Then, the threaded rod 42 is rotated to increase the angle between the deflecting two-link rod 45 and the threaded rod 42, so as to increase the distance between the triangular inner support ribs 46 and the threaded rod 42, so that a plurality of triangular inner support ribs 46 arranged at intervals are simultaneously abutted against the corner area of the inner wall surface of the waveguide tube blank (at this time, only simple contact and orientation profile) to perform shaping and inner support on the waveguide tube blank. The translation mechanism 32 is activated to drive the second main board 31 to move towards the first main board 21 so that the second main board 31 abuts against the side of the waveguide tube blank away from the first main board 21. The adjustable limit screw 332 of the adjustable clamping mechanism 33 is adjusted to make the limit pressing block 333 radially press against the radial outer wall of the waveguide tube blank. The threaded rod 42 is further screwed to make the triangular inner support ribs 46 strongly abut against the corner area of the inner wall surface of the waveguide tube blank, so that the tube wall of the waveguide tube blank is limited to a straightened state. After the milling process of one surface of the waveguide tube blank is completed, the radial clamping limit of the waveguide tube blank by the adjustable clamping mechanism 33 is released, and the translation mechanism 32 drives the second main board 31 to move away from the first main board 21 to release the end surface abutment limit on the waveguide tube blank. The positioning sleeve plate 23 is pulled to the left to separate it from the first main board 21, and then the positioning sleeve plate 3 is controlled to rotate, so that the plug post 22, the adjustable inner support assembly 4, and the waveguide tube blank rotate synchronously, so that the surface of another waveguide tube blank rotates to the processing station. The positioning sleeve plate 23 is moved to the right again to be connected to the first main board 21, so as to be fixed again. Then, the locking long screw 24 is screwed to position the relative positions among the first main board 21, the plug post 22, and the adjustable inner support assembly 4, and the transverse movement positioning assembly 3 is adjusted twice to limit and clamp the other end of the waveguide tube blank.
