To address this problem, the relevant technology (publication number CN219881708U) discloses a communication tower component processing steel welding device, which uses three anti-slip folding rods to clamp and fix the right-angled steels, which is more stable.

[0004] However, the above scheme is not suitable for the welding positioning needs of rectangular communication components such as circuit boards. Rectangular communication components on circuit boards often need to be placed flat for positioning in order to weld the upper surface of the circuit board. In addition, the traditional method of positioning the circuit board often uses universal clamps on the market, that is, the upper surface of the circuit board is positioned at two points in succession with the help of bolts and nuts. It is impossible to achieve simultaneous positioning of the two points, and the repeated disassembly and assembly of the nuts is relatively cumbersome. Utility Model Content

[0005] In view of the fact that some existing positioning devices in the prior art are not suitable for the welding positioning needs of rectangular communication components such as circuit boards, and in addition, positioning with the help of universal clamps on the market cannot achieve two-point synchronous positioning, and the repeated disassembly and assembly of nuts is cumbersome, the utility model provides a communication component welding positioning device, which can adapt to the welding positioning needs of rectangular communication components such as circuit boards, and can also synchronously achieve two-point positioning or disengagement of circuit boards. Compared with the traditional point-by-point positioning method, the positioning steps are simpler, and the cumbersome steps of the traditional repeated disassembly and assembly of nuts are omitted, and the circuit board can be positioned and welded more quickly and effectively. The specific technical scheme is as follows:

[0006] A communication component welding positioning device includes a circuit board and a base, wherein a vertical plate is vertically installed on the rear side of the upper surface of the base, a supporting plate is installed on the top of the front side wall of the vertical plate, the circuit board is placed on the upper surface of the supporting plate, and a positioning unit for synchronously positioning the circuit board at two points is arranged on the upper surface of the circuit board.

[0007] In the above technical solution, each group of the positioning components includes a mounting column vertically installed on the front side wall of the vertical plate, and also includes a limit pin installed on the front end of the mounting column. The outer wall of the limit pin is provided with a rotating arm, and the outer wall of the rotating arm is provided with a sliding groove for the limit pin to slide. The free end of the bottom end of the rotating arm is provided with a mounting groove, and a rod body is fixedly installed in the inner cavity of the mounting groove.

[0008] In the above technical solution, the driving component includes a cylinder vertically mounted on the upper surface of the base, the output end of the cylinder is connected to a lifting plate, and a driving pin is installed on the top of the lifting plate.

[0009] In the above technical solution, the driving pin is rotatably connected to the rod body.

[0010] In the above technical solution, a positioning seat is installed at the free end of the top end of the rotating arm, and a positioning block for positioning the circuit board is arranged on the outer wall of the positioning seat.

[0013] Compared with the prior art, the communication component welding positioning device of the utility model has the following beneficial effects:

[0014] 1.

[0015] Second, in order to solve the problem that the general-purpose clamps on the market cannot realize the synchronous positioning of two points, and the repeated disassembly and assembly of nuts is complicated, the utility model realizes the synchronous rotation of the two rotating arms on the left and right sides to the middle, so that the two positioning blocks on the left and right sides are synchronously close to or away from the upper surface of the circuit board, and the two-point positioning or separation of the circuit board can be realized synchronously. Compared with the traditional point-by-point positioning method, the positioning steps are simpler, and the complicated steps of the traditional repeated disassembly and assembly of nuts are omitted, so the circuit board can be positioned and welded more quickly and effectively;

[0019] In summary, the utility model can adapt to the welding positioning requirements of rectangular communication components such as circuit boards, and can also simultaneously realize two-point positioning or disengagement of the circuit board. Compared with the traditional point-by-point positioning method, the positioning steps are simpler and the tedious steps of repeated disassembly and assembly of nuts are eliminated.

In this embodiment, the circuit board 4 is used as the communication component for explanation, and also includes a base 1. A vertical plate 2 is vertically installed on the rear side of the upper surface of the base 1, and a supporting plate 3 is installed on the top of the front side wall of the vertical plate 2. The circuit board 4 is placed on the upper surface of the supporting plate 3. Rectangular communication components such as the circuit board 4 are placed through the supporting plate 3 for subsequent positioning and welding. A positioning unit for synchronously positioning the circuit board 4 at two points is provided on the upper surface of the circuit board 4. Compared with the traditional single-point positioning method, synchronous positioning of two points on the upper surface of the circuit board 4 can be achieved. The positioning unit includes two groups of positioning components and a driving component, wherein the two groups of positioning units are symmetrically arranged with the supporting plate 3 as the axis, thereby ensuring that the two groups of positioning units can synchronously and symmetrically position the two sides of the circuit board 4, and can better ensure the stability of the circuit board 4 after positioning, and the two groups of positioning units are prompted to perform two-point synchronous positioning of the circuit board 4 through the driving component.

[0026] See also Figure 1 and Figure 3As shown, each group of positioning components includes a mounting column 5 vertically mounted on the front side wall of the vertical plate 2, and also includes a limit pin 6 installed on the front end of the mounting column 5. The mounting column 5 provides support for the installation of the limit pin 6. The outer wall of the limit pin 6 is provided with a rotating arm 7, and the outer wall of the rotating arm 7 is provided with a slide groove 8 for the limit pin 6 to slide. When the free end of the bottom end of the rotating arm 7 is forced to rotate, the limit pin 6 can be prompted to move along the inner cavity of the slide groove 8, and the top free end of the rotating arm 7 can be prompted to rotate outward to prompt the top free end of the rotating arm 7 to move away from the upper surface of the circuit board 4. A mounting groove 17 is provided at the bottom free end of the rotating arm 7, and a rod body 18 is fixedly installed in the inner cavity of the mounting groove 17. By driving the rod body 18 to move up and down, the rotating arm 7 can be smoothly driven to rotate the rod outward or inward, so as to subsequently realize the circuit board. 4 two-point synchronous positioning or synchronous disengagement positioning; the driving component includes a cylinder 14 vertically mounted on the upper surface of the base 1, the cylinder 14 is a self-locking cylinder commonly used on the market, and its output end can stay at any position and lock, and its model is not limited here, the output end of the cylinder 14 is connected to a lifting plate 15, and a driving pin 16 is installed on the top of the lifting plate 15. The opened cylinder 14 can drive the lifting plate 15 and the driving pin 16 to move synchronously up and down; the driving pin 16 is rotatably connected to the rod body 18 through a bearing, and when the driving pin 16 moves downward, the rod body 18 is prompted to move downward synchronously, and the driving pin 16 and the rod body 18 are prompted to rotate relative to each other, and the free end of the bottom end of the rotating arm 7 is prompted to move downward under the drive of the rod body 18, so as to prompt the free end of the top end of the rotating arm 7 to move upward or rotate outward;

[0027] In addition, by providing a slide groove 8 on the outer wall of the rotating arm 7, sufficient space can be left for the limit pin 6 to slide in the inner cavity of the slide groove 8, and the positioning block 12 can be vertically separated from the upper surface of the circuit board 4 by the vertical displacement of the rotating arm 7. Compared with the rotational connection between the rotating arm 7 and the limit pin 6, the problem of the rotating arm 7 driving the positioning block 12 to directly rotate and separate from the circuit board 4 and cause damage to the surface of the circuit board 4 can be avoided, and the integrity of the circuit board 4 can be more effectively protected.

[0028] Specific reference Figure 3As shown, a positioning seat 9 is installed at the free end of the top of the rotating arm 7, and a positioning block 12 for positioning the circuit board 4 is provided on the outer wall of the positioning seat 9. The positioning seat 9 and the positioning block 12 are driven to move synchronously by the rotation of the rotating arm 7 to realize the positioning or disengagement of the positioning block 12 at the circuit board 4; an adjusting groove 10 is provided through the outer wall of the positioning seat 9, and a screw 11 is slidably embedded in the inner cavity of the adjusting groove 10. The outer wall of the screw 11 is provided with an external thread, and a nut 13 is threadedly sleeved on the outer wall of the screw 11, and the outer wall of the nut 13 is fitted with the upper surface of the positioning seat 9, and the positioning block 12 is installed at the bottom end of the screw 11. The screw 11 is moved along the inner cavity of the adjusting groove 10 to prompt the positioning block 12 at the bottom end of the screw 11 to move to a suitable position, and then the screw 11 is rotated in the opposite direction to prompt the screw 11 to re-fit the upper surface of the positioning seat 9, so as to position the positioning block 12 after the movement, thereby realizing the adjustment of the position of the positioning block 12.

[0029] In order to ensure that the supporting plate 3 has sufficient supporting force, a reinforcing rod 19 is obliquely installed between the vertical plate 2 and the supporting plate 3. The reinforcing rod 19 increases the connection between the supporting plate 3 and the vertical plate 2 to ensure that the position of the supporting plate 3 is more stable.

[0031] The circuit board 4 is placed on the upper surface of the supporting plate 3, and the lifting plate 15, the driving pin 16 and the rod body 18 are synchronously moved toward each other by the opened cylinder 14, so as to drive the free ends of the bottom ends of the two rotating arms 7 on the left and right sides to move downward synchronously, and the slide groove 8 is moved downward along the outer wall of the limit pin 6. At this time, the positioning block 12 arranged at the free end of the top end of the rotating arm 7 moves downward synchronously, and the upper surface of the circuit board 4 is synchronously positioned at two points;

[0032] When it is necessary to adjust the positioning position of the positioning block 12 relative to the circuit board 4, the nut 13 is rotated to cause it to separate from the outer wall of the positioning seat 9, and the screw rod 11 is moved along the inner cavity of the adjustment groove 10. After the positioning block 12 at the bottom end of the screw rod 11 moves to a suitable position, the screw rod 11 is rotated in the opposite direction to cause the screw rod 11 to re-attach to the upper surface of the positioning seat 9, and the positioning block 12 after the movement is positioned, thereby realizing the adjustment of the position of the positioning block 12;

[0033] The utility model can adapt to the welding positioning requirements of rectangular communication components such as circuit boards 4, and can also simultaneously realize two-point positioning or disengagement of the circuit board 4. Compared with the traditional point-by-point positioning method, the positioning steps are simpler and the tedious steps of the traditional repeated disassembly and assembly of nuts are omitted. The circuit board 4 can be positioned and welded more quickly and effectively. In addition, the positioning block 12 is vertically upward and separated from the upper surface of the circuit board 4 to avoid damage to the surface of the circuit board 4, and can more effectively protect the integrity of the circuit board 4. The position of the positioning block 12 can be adjusted, and it has strong versatility.
