A fixture device for automatic welding of an antenna element

Abstract

This utility model discloses a fixture device for automatic welding of antenna elements, including a base, an adjusting column, an adjusting frame, and a clamping frame. The rear side of the top of the base is movably connected to the bottom of the adjusting column, and the front side of the adjusting column is movably connected to the back side of the adjusting frame via a pivot pin. The two sides of the clamping frame are fixedly connected to the two sides of the inner wall of the adjusting frame. This utility model, by setting a lifting rod and a lifting block, utilizes a lifting groove to restrict the movement direction of the lifting block, allowing the lifting rod to rotate while the lifting block cannot follow the rotation of the lifting rod. Consequently, the lifting block moves up and down within the lifting groove, making it convenient for the user to adjust the height of the clamping frame. This solves the problem that while the welding fixture allows for easy adjustment of the clamping angle, it lacks a structure for adjusting the fixture height. If the height is not adjustable, the robot needs to frequently modify the programming path to adapt to different workpieces, increasing debugging costs and potentially causing the automation program to fail due to positioning errors.

Description

Technical Field

[0001] This utility model relates to the field of antenna vibrator technology, specifically to a clamping device for automatic welding of antenna vibrators. Background Technology

[0002] Antennas are a core and essential component of wireless communication equipment, and their design significantly impacts wireless communication performance. The vibrator is a key element of the antenna, guiding and amplifying electromagnetic waves to enhance the received and transmitted electromagnetic signals. The design of the vibrator is central to antenna design.

[0003] For example, according to authorization announcement number CN211361188U, this utility model provides a fixture for welding antenna elements, including a base plate, a column, a first frame, and a second frame. The column is vertically mounted on the base plate. A first rotating shaft is horizontally positioned between the column and the first frame. A second rotating shaft is vertically positioned between the first and second frames. The second frame has a first clamping part and a second clamping part, which are arranged parallel to each other and are used to fix the PCB board and reflector of the antenna element, respectively. This fixture for welding antenna elements can rotate at multiple angles. By rotating the first frame, the horizontal surface of the antenna element to be welded can be flipped. By rotating the second frame, the horizontal surface of the antenna element to be welded can be rotated. The visual position and operating space of the area to be welded can be rotated to an angle that is easy to operate at any time, facilitating the welding operation of the antenna element to be welded.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that the clamping angle of existing PCB oscillator welding fixtures is fixed, making it inconvenient for workers to weld PCB oscillators and potentially leading to incomplete welding and amplifying the defects of the PCB oscillator, during use, although the welding fixture allows users to easily adjust the clamping angle, it does not have a structure for adjusting the fixture height. If the height is not adjustable, the robot needs to frequently modify the programming path to adapt to different workpieces, increasing debugging costs, and may even cause the automation program to fail to run due to positioning errors. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a clamping device for automatic welding of antenna elements, which has the advantage of auxiliary adjustment. It solves the problem that while the welding clamp can be easily adjusted by the user to adjust the clamping angle, it does not have a structure to facilitate the adjustment of the clamping height. If the height is not adjustable, the robot needs to frequently modify the programming path to adapt to different workpieces, which increases debugging costs and may even cause the automation program to fail to run due to positioning errors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for automatic welding of antenna elements, comprising a base, an adjusting column, an adjusting frame, and a clamping frame. The rear side of the top of the base is movably connected to the bottom of the adjusting column. The front side of the adjusting column is movably connected to the back side of the adjusting frame via a pivot pin. The two sides of the clamping frame are fixedly connected to the two sides of the inner wall of the adjusting frame. A lifting groove is provided on the front side of the adjusting column. A lifting rod is movably connected to the bottom of the inner wall of the lifting groove via a pivot pin. A lifting block is threaded onto the surface of the lifting rod. The front side of the lifting block is fixedly connected to the back side of the adjusting frame. A moving component is provided on the top of the base. Connecting components are fixedly connected to the bottom of the two sides of the adjusting column.

[0007] In a preferred embodiment of this invention, the movable component includes a movable groove, which is located at the top of the base. A forward and reverse lead screw is movably connected to the front side of the inner wall of the movable groove via a shaft pin. A movable block is threadedly connected to the surface of the forward and reverse lead screw. The surface of the movable block is slidably connected to the inner wall of the movable groove, and the top of the movable block is movably connected to the bottom of the adjusting column.

[0008] In a preferred embodiment of this utility model, the connecting assembly includes a fixing plate, the inner side of which is fixedly connected to the bottom of both sides of the adjusting column, a connecting plate fixedly connected to the top of the moving block, the top of the connecting plate contacting the bottom of the adjusting column, and reinforcing grooves provided on both sides of the top of the fixing plate and the top of the connecting plate, with reinforcing rods threadedly connected to the inner wall of the reinforcing grooves.

[0009] As a preferred embodiment of this utility model, the top of the connecting plate is provided with a guide groove, and a guide block is slidably connected to the inner wall of the guide groove. The top of the guide block is fixedly connected to the bottom of the adjusting column.

[0010] As a preferred embodiment of this utility model, a rotating block is fixedly connected to the top of the reinforcing rod, and an auxiliary strip is fixedly connected to the surface of the rotating block. The auxiliary strip is provided in a plurality of pieces and is distributed in a ring at equal intervals.

[0011] As a preferred embodiment of this utility model, storage slots are provided on both sides of the base, and storage boxes are slidably connected to the inner walls of the storage slots.

[0012] As a preferred embodiment of this utility model, both sides of the inner wall of the storage groove are provided with sliding grooves, and the inner wall of the sliding groove is also connected to a slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a lifting rod and a lifting block, utilizes a lifting groove to restrict the movement direction of the lifting block, so that the lifting rod rotates while the lifting block cannot follow the rotation of the lifting rod. As a result, the lifting block will move up and down inside the lifting groove, which makes it convenient for the user to adjust the height of the clamping frame. This solves the problem that while the welding fixture can be easily adjusted by the user to adjust the clamping angle, it does not have a structure to facilitate the adjustment of the fixture height. If the height is not adjustable, the robot needs to frequently modify the programming path to adapt to different workpieces, increasing debugging costs, and may even cause the automation program to fail to run due to positioning errors. This achieves the effect of auxiliary adjustment.

[0015] 2. This utility model, by setting a moving component, allows the user to first rotate the forward and reverse screws when the position of the adjusting column needs to be moved. Since the moving groove can restrict the movement direction of the moving block, the moving block cannot follow the forward and reverse screws to rotate inside the moving groove. As the forward and reverse screws rotate, the moving block will move back and forth in the moving groove, which makes it convenient for the user to adjust the position of the clamping frame. The self-locking characteristic of the threaded transmission can prevent the adjusting column from being displaced due to welding vibration. Combined with the limiting sliding of the moving groove, the effect of assisting the adjusting column to move back and forth is achieved.

[0016] 3. By setting up a connecting component, when the user needs to connect the adjusting column and the moving block, first connect the bottom of the adjusting column to the top of the connecting plate, so that the reinforcing groove on the top of the fixed plate is connected to the reinforcing grooves on both sides of the top of the connecting plate. Then, align the reinforcing rod with the reinforcing groove, and rotate the reinforcing rod so that the reinforcing rod is completely moved into the inside of the reinforcing groove. The reinforcing rod can be used to fix the fixed plate and the connecting plate together, and then the moving block can drive the adjusting column to move back and forth, thereby achieving the effect of assisting the connection between the adjusting column and the moving block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a clamping device for automatic welding of antenna elements, comprising a base 1, an adjusting column 2, an adjusting frame 3, and a clamping frame 4. The rear side of the top of the base 1 is movably connected to the bottom of the adjusting column 2. The front side of the adjusting column 2 is movably connected to the back side of the adjusting frame 3 via a pivot pin. The two sides of the clamping frame 4 are fixedly connected to the two sides of the inner wall of the adjusting frame 3. A lifting groove 5 is provided on the front side of the adjusting column 2. A lifting rod 6 is movably connected to the bottom of the inner wall of the lifting groove 5 via a pivot pin. A lifting block 7 is threadedly connected to the surface of the lifting rod 6. The front side of the lifting block 7 is fixedly connected to the back side of the adjusting frame 3. A moving component 8 is provided on the top of the base 1. Connecting components 9 are fixedly connected to the bottom of the two sides of the adjusting column 2.

[0023] refer to Figure 2 The movable component 8 includes a movable groove 81, which is opened on the top of the base 1. The front side of the inner wall of the movable groove 81 is movably connected to a forward and reverse lead screw 82 via a shaft pin. The surface of the forward and reverse lead screw 82 is threadedly connected to a movable block 83. The surface of the movable block 83 is slidably connected to the inner wall of the movable groove 81, and the top of the movable block 83 is movably connected to the bottom of the adjusting column 2.

[0024] As a technical optimization of this utility model, by setting the moving component 8, when the user needs to move the position of the adjusting column 2, first rotate the forward and reverse screw 82. Since the moving groove 81 can restrict the moving direction of the moving block 83, the moving block 83 cannot follow the forward and reverse screw 82 to rotate inside the moving groove 81. As the forward and reverse screw 82 rotates, the moving block 83 will move back and forth in the moving groove 81, which makes it convenient for the user to adjust the position of the clamping frame 4. The self-locking characteristic of the threaded transmission can prevent the adjusting column 2 from being displaced due to welding vibration. With the limiting sliding of the moving groove 81, the effect of assisting the adjusting column 2 to move back and forth is achieved.

[0025] refer to Figure 3 The connecting component 9 includes a fixing plate 91, the inner side of which is fixedly connected to the bottom of both sides of the adjusting column 2. A connecting plate 92 is fixedly connected to the top of the moving block 83. The top of the connecting plate 92 is in contact with the bottom of the adjusting column 2. Reinforcing grooves 93 are provided on both sides of the top of the fixing plate 91 and the top of the connecting plate 92. A reinforcing rod 94 is threadedly connected to the inner wall of the reinforcing groove 93.

[0026] As a technical optimization of this utility model, by setting the connecting component 9, when the user needs to connect the adjusting column 2 and the moving block 83, first connect the bottom of the adjusting column 2 to the top of the connecting plate 92, so that the reinforcing groove 93 on the top of the fixing plate 91 is connected to the reinforcing grooves 93 on both sides of the top of the connecting plate 92. Then, align the reinforcing rod 94 with the reinforcing groove 93. At this time, rotate the reinforcing rod 94 so that the reinforcing rod 94 is completely moved into the interior of the reinforcing groove 93. The fixing plate 91 and the connecting plate 92 can be fixed together by the reinforcing rod 94, and then the moving block 83 can drive the adjusting column 2 to move back and forth, thereby achieving the effect of assisting the connection between the adjusting column 2 and the moving block 83.

[0027] refer to Figure 3 The top of the connecting plate 92 is provided with a guide groove 10, and the inner wall of the guide groove 10 is slidably connected with a guide block 11. The top of the guide block 11 is fixedly connected to the bottom of the adjusting column 2.

[0028] As a technical optimization of this utility model, by setting guide groove 10 and guide block 11, when the user needs to align the reinforcing groove 93 on the fixing plate 91 with the reinforcing groove 93 on the connecting plate, first align the bottom of the guide block 11 with the guide groove 10, and then move the adjusting column 2 downward so that the guide block 11 moves completely into the interior of the guide groove 10. The guide groove 10 can restrict the movement direction of the guide block 11, so that the adjusting column 2 is more stably connected with the moving block 83. At this time, the reinforcing groove 93 on the fixing plate 91 is connected with the reinforcing groove 93 on the connecting plate 92, thereby achieving the effect of assisting the installation of the adjusting column 2.

[0029] refer to Figure 3A rotating block 12 is fixedly connected to the top of the reinforcing rod 94, and an auxiliary strip 13 is fixedly connected to the surface of the rotating block 12. Several auxiliary strips 13 are provided and are distributed in a ring at equal intervals.

[0030] As a technical optimization of this utility model, by setting the rotating block 12 and the auxiliary strip 13, when the user needs to rotate the reinforcing rod 94, the auxiliary block can increase the contact area between the user and the reinforcing rod 94, giving the user a larger point of force application. Furthermore, the multiple auxiliary strips 13 can increase the friction between the user and the rotating block 12, preventing the user from slipping, thereby achieving the effect of assisting the rotation of the reinforcing rod 94.

[0031] refer to Figure 2 The base 1 has storage slots 14 on both sides, and storage boxes 15 are slidably connected to the inner wall of the storage slots 14.

[0032] As a technical optimization of this utility model, by setting up a storage slot 14 and a storage box 15, the storage box 15 can be used to classify and store small accessories such as welding torch nozzles, electrode caps, and calibration templates, reducing the time for operators to go back and forth to retrieve parts, which is in line with the "single-piece flow" principle of lean production. The storage box 15 is embedded inside the base 1 to prevent welding spatter from entering, and the sliding structure can lock the position to prevent accessories from falling off during equipment movement, thereby improving the 5S management level of the workshop and achieving the effect of assisting in parts storage.

[0033] refer to Figure 2 The inner walls of the storage slot 14 are provided with sliding grooves 16 on both sides, and the inner walls of the sliding grooves 16 are connected to sliders 17.

[0034] As a technical optimization of this utility model, by setting the slide groove 16 and the slider 17, when the user pulls out the storage box 15, since the inner side of the slider 17 is fixedly connected to the two sides of the storage box 15, the slider 17 will move left and right inside the slide groove 16. The slide groove 16 can restrict the movement direction and final position of the slider 17, making the movement of the storage box 15 more stable, and at the same time preventing the storage box 15 from falling out of the storage groove 14, thereby achieving the effect of assisting the movement of the storage box 15.

[0035] The working principle and usage of this utility model are as follows: During use, the lifting groove 5 restricts the movement direction of the lifting block 7, causing the lifting rod 6 to rotate while the lifting block 7 cannot follow. Consequently, the lifting block 7 moves up and down within the lifting groove 5, facilitating user adjustment of the clamping frame 4's height. When the user needs to move the position of the adjusting column 2, first rotate the forward and reverse screw 82. Because the moving groove 81 restricts the movement direction of the moving block 83, the moving block 83 cannot follow the forward and reverse screw 82 to rotate within the moving groove 81. Therefore, as the forward and reverse screw 82 rotates, the moving block 83 moves back and forth within the moving groove 81, facilitating user adjustment of the clamping frame 4. The self-locking characteristic of the threaded drive prevents the adjusting column 2 from shifting due to welding vibration. Combined with the limiting sliding of the moving groove 81, when the user needs to connect the adjusting column 2 to the moving block 83, first connect the bottom of the adjusting column 2 to the top of the connecting plate 92, so that the reinforcing groove 93 on the top of the fixing plate 91 is connected to the reinforcing grooves 93 on both sides of the top of the connecting plate 92. Then align the reinforcing rod 94 with the reinforcing groove 93. At this time, rotate the reinforcing rod 94 so that it moves completely into the interior of the reinforcing groove 93. The reinforcing rod 94 can then fix the fixing plate 91 and the connecting plate 92 together, thereby allowing the moving block 83 to drive the adjusting column 2 to move back and forth, thus achieving the effect of auxiliary adjustment.

[0036] In summary, this automatic welding fixture for antenna elements, by setting up a lifting rod 6 and a lifting block 7, and using a lifting groove 5 to restrict the movement direction of the lifting block 7, allows the lifting rod 6 to rotate while the lifting block 7 cannot follow the rotation of the lifting rod 6. As a result, the lifting block 7 moves up and down inside the lifting groove 5, which makes it convenient for the user to adjust the height of the clamping frame 4. This solves the problem that while the welding fixture allows the user to adjust the clamping angle, it does not have a structure for adjusting the height of the fixture. If the height is not adjustable, the robot needs to frequently modify the programming path to adapt to different workpieces, increasing debugging costs, and may even cause the automation program to fail to run due to positioning errors.
