Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, specifically to a clamping mechanism for waveguide processing. Background Technology

[0002] In the fields of microwave communication and radar systems, waveguides serve as the core carriers for millimeter-wave / terahertz band signal transmission, and their processing accuracy directly affects electromagnetic wave transmission efficiency and standing wave ratio (VSWR) performance. Traditional clamping mechanisms employ split-type mechanical chucks or pneumatic adsorption schemes, which suffer from three technical bottlenecks: First, irregularly shaped cavities (such as ridged waveguides or gradually elliptical structures) are prone to asymmetric stress during clamping, leading to micron-level deformation in thin-walled parts (wall thickness 0.3±0.02mm); second, the centrifugal effect (speed > 8000rpm) in 5-axis linkage machining can induce resonance in the fixture-workpiece system, causing surface roughness deterioration to over Ra 0.8μm; third, existing clamping schemes lack in-situ dielectric constant compensation mechanisms, resulting in an increase of 0.15dB / m in dielectric loss of aluminum alloy waveguides under clamping force. These defects severely restrict the mass production yield of Q-band (33-50GHz) waveguide devices, necessitating the development of new intelligent clamping systems with dynamic stiffness control and dielectric property preservation capabilities.

[0003] The utility model patent with application number CN202021728266.5 and publication number CN212967989U (hereinafter referred to as "Prior Art 1") discloses a waveguide assembly with a clamping mechanism, including: a waveguide to be connected, a retaining ring set at the end of the waveguide, a tightening device set on the side wall of the retaining ring, an operating table for the connection operation of the waveguide, a mounting rod for fixing the waveguide to the operating table, and a connecting rod for connecting the mounting rod and the retaining ring. The tightening device is used to control the opening and closing of the retaining ring.

[0004] The specification of prior art 1 discloses a waveguide assembly with a clamping mechanism. In use, the waveguide is clamped by controlling the retaining ring through a tightening device. However, in actual applications, manual adjustment is required to clamp the waveguide, resulting in low efficiency and poor performance when clamping the waveguide. Summary of the Invention

[0005] This invention provides a clamping mechanism for waveguide processing, which aims to solve the problem that existing waveguides require manual clamping, resulting in low efficiency when clamping waveguides.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A clamping mechanism for waveguide processing includes a base, a magnetic attraction device, and a clamping device; the base is used to be mounted on a plane; the magnetic attraction device is used to magnetically attract a metal tube; the clamping device is disposed on the base and is used to clamp and fix the metal tube.

[0008] The clamping device includes a telescopic component, a first hinge frame, and a second hinge frame. Both the first and second hinge frames are hinged to the bottom of the base. The movable end of the telescopic component passes through the base and is connected to a hinge block. The hinge block is fixedly connected to the first hinge frame. The first and second hinge frames are connected through a transmission mechanism. The telescopic component is used to drive the first and second hinge frames to rotate relative to or opposite to each other on the base through the transmission mechanism.

[0009] Furthermore, a mounting plate is provided at the bottom of the base, and both the first hinge frame and the second hinge frame are rotatably mounted on the mounting plate.

[0010] Furthermore, the first hinge frame and the second hinge frame have the same structure. The first hinge frame includes a clamping block and a rotating rod. The rotating rod is rotatably mounted on the mounting plate. The clamping blocks are fixedly mounted at both ends of the rotating rod. The hinge block is fixedly mounted on one of the clamping blocks on the first hinge frame. The transmission mechanism is used to be mounted on the rotating rod.

[0011] Furthermore, the transmission mechanism includes a driving gear and a driven gear, which are respectively fixedly mounted on rotating rods on the first hinge frame and the second hinge frame, and the driving gear and the driven gear mesh with each other.

[0012] Furthermore, the telescopic assembly can be a pneumatic telescopic assembly, an electric telescopic assembly, or a hydraulic telescopic assembly.

[0013] Furthermore, a hinge frame is provided on the base, and an installation sleeve is provided on the outer wall of the telescopic component.

[0014] Furthermore, the base is provided with a clearance groove, and the movable end of the telescopic component is used to pass through the clearance groove and then hinge with the hinge block.

[0015] Furthermore, the magnetic attraction assembly includes a first electromagnet and a cylinder. The cylinder is mounted on the base, and the movable end of the cylinder passes through the base and is connected to the first electromagnet. The metal tube is used to attract the first electromagnet.

[0016] Furthermore, a mounting bracket is provided on the base, and a second electromagnet is provided on the top of the mounting bracket. The end face of the second electromagnet is used for mounting on a plane.

[0017] Furthermore, a toothed rubber pad is provided on the end face of the clamping block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model mainly includes a base, a magnetic suction device, and a clamping device. In actual use, when clamping a metal tube, the operator first places the metal tube on the magnetic suction device to initially fix it. Since the magnetic suction fixation method is unstable, the clamping device is needed to hold the metal tube. During this process, the operator needs to control the telescopic component to retract. After the telescopic component retracts, it drives the first hinge frame to rotate. The first hinge frame drives the second hinge frame to rotate in opposite directions with the first hinge frame through a transmission mechanism, thereby clamping the metal tube. The advantage of this design is that there is no need to manually clamp the metal tube; the telescopic component can easily achieve the purpose of clamping the metal tube. Stable clamping facilitates the processing of the metal tube. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0026] Please see Figure 1-3 As shown, this embodiment discloses a clamping mechanism for waveguide processing, including a base 101, a magnetic attraction device, and a clamping device; the base 101 is used to be mounted on a plane; the magnetic attraction device is used to magnetically attract the metal tube 102; the clamping device is disposed on the base 101 and is used to clamp and fix the metal tube 102.

[0027] The clamping device includes a telescopic component 103, a first hinge frame 104, and a second hinge frame 105. Both the first hinge frame 104 and the second hinge frame 105 are hinged to the bottom of the base 101. The movable end of the telescopic component 103 passes through the base 101 and is connected to a hinge block 106. The hinge block 106 is fixedly connected to the first hinge frame 104. The first hinge frame 104 and the second hinge frame 105 are connected through a transmission mechanism. The telescopic component 103 is used to drive the first hinge frame 104 and the second hinge frame 105 to rotate relative to or opposite to each other on the base 101 through the transmission mechanism.

[0028] This utility model mainly includes a base 101, a magnetic suction device, and a clamping device. In actual use, when the operator clamps the metal tube 102, the metal tube 102 is first placed on the magnetic suction device to initially fix the metal tube 102. Since the magnetic suction fixation method is unstable, the clamping device is needed to clamp the metal tube 102. During this process, the operator needs to control the telescopic component 103 to retract. After the telescopic component 103 retracts, it drives the first hinge frame 104 to rotate. The first hinge frame 104 drives the second hinge frame 105 to rotate in opposite directions with the first hinge frame 104 through the transmission mechanism, thereby clamping the metal tube 102. The advantage of this design is that there is no need to manually clamp the metal tube 102. The purpose of clamping the metal tube 102 can be easily achieved by the telescopic component 103. The stable clamping facilitates the processing of the metal tube 102.

[0029] In some embodiments, a mounting plate 107 is provided at the bottom of the base 101, and the first hinge frame 104 and the second hinge frame 105 are both rotatably mounted on the mounting plate 107.

[0030] In actual use, there are two mounting plates 107. Both mounting plates 107 are set at the bottom of the base 101. The two ends of the first hinge frame 104 and the second hinge frame 105 are respectively rotatably mounted on the two mounting plates 107. The purpose of setting the mounting plates 107 is to install the first hinge frame 104 and the second hinge frame 105.

[0031] In some embodiments, the first hinge frame 104 and the second hinge frame 105 have the same structure. The first hinge frame 104 includes a clamping block 108 and a rotating rod 109. The rotating rod 109 is rotatably mounted on the mounting plate 107. The clamping blocks 108 are fixedly mounted at both ends of the rotating rod 109. The hinge block 106 is fixedly mounted on one of the clamping blocks 108 on the first hinge frame 104. A transmission mechanism is used to be mounted on the rotating rod 109.

[0032] In actual use, the first hinge frame 104 and the second hinge frame 105 have the same structure. In order to distinguish their positions, the hinge frames 112 are named the first and second. There are two clamping blocks 108, which are respectively set at both ends of the rotating rod 109. The first hinge frame 104 rotates on the mounting plate 107 by extending and shortening the telescopic component 103. Under the action of the transmission mechanism, the first hinge frame 104 rotates and drives the second hinge frame 105 to rotate in the opposite direction.

[0033] In some embodiments, the transmission mechanism includes a drive gear 110 and a driven gear 111. The drive gear 110 and the driven gear 111 are respectively fixedly mounted on the rotating rod 109 on the first hinge frame 104 and the second hinge frame 105, and the drive gear 110 and the driven gear 111 mesh with each other.

[0034] In actual use, when the telescopic component 103 controls the first hinge frame 104 to rotate, it drives the drive gear 110 to rotate. Since the drive gear 110 and the driven gear 111 mesh with each other, the rotation of the first hinge frame 104 drives the second hinge frame 105 to rotate in the opposite direction, thereby achieving the purpose of controlling the first hinge frame 104 and the second hinge frame 105 to rotate relative to or opposite to each other through the telescopic component 103.

[0035] In some embodiments, the telescopic component 103 is a pneumatic telescopic component 103, an electric telescopic component 103, or a hydraulic telescopic component 103.

[0036] As an optional implementation, in this embodiment, the telescopic component 103 is an electric telescopic component 103, specifically an electric telescopic rod in the prior art. It should be noted that in this embodiment, the electric telescopic rod is prior art, and this embodiment does not involve any improvement to the structure of the electric telescopic rod. Controlling the extension of the electric telescopic rod is also prior art, and this embodiment does not involve any improvement to the control of the electric telescopic rod. All of these methods use the prior art for controlling the electric telescopic rod, which will not be described in detail here.

[0037] In some embodiments, a hinge frame 112 is provided on the base 101, and a mounting sleeve 113 is provided on the outer wall of the telescopic component 103. The inner wall of the mounting sleeve 113 is hinged to the telescopic component 103, and the outer wall of the mounting sleeve 113 is hinged to the hinge frame 112.

[0038] In actual use, the mounting sleeve 113 is fixedly installed on the outer wall of the telescopic component 103 and hinged to the hinge frame 112. The purpose of setting the hinge frame 112 is to facilitate the telescopic component 103 to be hinged to the base 101.

[0039] In some embodiments, a clearance groove 114 is provided on the base 101, and the movable end of the telescopic component 103 is used to pass through the clearance groove 114 and then hinge with the hinge block 106.

[0040] In actual use, since the telescopic component 103 will swing during the process of extension and retraction, the purpose of setting the clearance groove 114 is to make way for the movable end of the telescopic component 103, so as to facilitate the movement of the movable end of the telescopic component 103.

[0041] In some embodiments, the magnetic attraction assembly includes a first electromagnet 115 and a cylinder 116. The cylinder 116 is disposed on the base 101, and the movable end of the cylinder 116 passes through the base 101 and is connected to the first electromagnet 115. The metal tube 102 is used to attract the first electromagnet 115.

[0042] In actual use, the cylinder 116 drives the first electromagnet 115 to adjust the height, so as to attract the metal tube 102. After the first electromagnet 115 is opened, the metal tube 102 is attracted.

[0043] In some embodiments, a mounting bracket 117 is provided on the base 101, and a second electromagnet 118 is provided on the top of the mounting bracket 117. The end face of the second electromagnet 118 is used for mounting on a plane.

[0044] In actual use, the purpose of setting up the mounting bracket 117 is to facilitate the installation of the second electromagnet 118. In order to facilitate the fixing of the position of the base 101, the base 101 can be fixed on the plane after the second electromagnet 118 is opened.

[0045] In some embodiments, a toothed rubber pad 119 is provided on the end face of the clamping block 108.

[0046] In actual use, the purpose of setting the toothed rubber pad 119 is to increase the friction between the clamping block 108 and the metal tube 102, so that the clamping block 108 can clamp the metal tube 102 more stably.
