Description

Technical Field

[0001] This utility model relates to the field of jigs and fixtures, and in particular to a multi-pin synchronous solder wrapping jig. Background Technology

[0002] Multi-pin synchronous solder wrapping fixtures are specialized tools used in the electronics manufacturing industry for high-precision soldering. They are mainly used for efficient and uniform soldering of electronic components with dense pins (such as connectors, chips, pin headers, etc.). However, in the existing technology, a single fixture can usually only correspond to a specific pin pitch and a specific number of pins for a component. For example, a 2.0mm pitch pin header fixture cannot be used for a 2.54mm pitch female header. Factories need to equip corresponding fixtures for thousands of different specifications of components, resulting in high fixture management costs and wasted storage space. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-pin synchronous soldering wrapping fixture.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a multi-pin synchronous solder wrapping fixture, comprising: Tool shell; A large-area fixing assembly includes an inner slide plate slidably connected within a fixture housing. A triangular block is slidably connected to the inner slide plate via a fixed shaft. A side frame and another triangular block are fixedly connected to the triangular block. A fixed rod is fixedly connected to the bottom of the inner slide plate. A piston plate is slidably connected to the fixed rod. A fixed frame is slidably connected to the piston plate. The fixed frame is fixedly connected within the fixture housing. A transmission block is slidably connected to the transmission block via an extension rod. A guide frame is slidably connected to the guide frame. A pin insertion port is slidably connected to the guide rail. An opening is formed on the guide rail.

[0005] In a preferred embodiment, oblique holes are provided on both the triangular block and the transmission block, and the fixed shaft and the transmission shaft are slidably connected in the oblique holes on the triangular block and the transmission block, respectively. Through holes are provided on both the transmission block and the inner slide plate.

[0006] The above technical solution is adopted: when in use, oblique holes are opened on the triangular block and the transmission block, so that the fixed shaft and the transmission shaft can slide in them, thereby driving the triangular block and the transmission block to move.

[0007] In a preferred embodiment, the guide frame has a transverse hole, a sliding rod is slidably connected in the transverse hole, the sliding rod has a threaded groove, and a tightening block is threadedly connected to the threaded groove on the sliding rod.

[0008] The above technical solution is adopted as follows: When in use, a horizontal hole is opened on the guide frame to facilitate the sliding rod to slide in it. The operator manually tightens the tightening block, which is driven to move closer to the jig housing and is locked on the jig housing to fix the guide frame. Tightening blocks are fixed on both sides of the sliding rod.

[0009] In a preferred embodiment, an extension plate is connected inside the fixture housing, an inner clamping frame is fixedly connected to the extension plate, a side frame is fixedly connected to the inner clamping frame, a transmission plate is fixedly connected to the side frame, a transmission shaft is fixedly connected to the transmission plate, the transmission shaft is slidably connected inside the transmission block, an inner groove is opened inside the fixture housing, and the upper and lower ends of the side frame are slidably connected to the inner groove of the fixture housing.

[0010] The above technical solution is adopted: when in use, an inner clamping frame is fixedly connected to the extension plate. The side frame is set to facilitate the transmission plate to drive the transmission shaft to move. When the inner clamping frame is driven to slide inward, the transmission plate will be driven to move synchronously.

[0011] In a preferred embodiment, the inner slide plate has a slot, and the fixed shaft is fixedly connected to the slot on the inner slide plate.

[0012] The above technical solution is adopted: a slot is opened on the inner slide plate, and the triangular block is embedded in the slot and will be moved together.

[0013] In a preferred embodiment, the fixture housing has an opening, and the extension rod is slidably connected to the opening in the fixture housing.

[0014] The above technical solution is adopted: by opening a hole in the jig housing, the extension rod slides vertically through the opening in the jig during use, so as to avoid the extension rod being blocked and unable to move.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model achieves full-dimensional adaptability through a three-level adjustable structure. The pin insertion port slides and locks along the guide rail to match different pin spacings. The guide rail, combined with the triangular block oblique hole transmission, enables overall position adjustment to accommodate different pin numbers. The inner clamping frame, linked to the side frame sliding and fixed with multi-position bolts, can accommodate workpieces of different sizes, significantly reducing the need for dedicated fixtures. The oblique hole transmission mechanism synchronously converts the inner slide plate pressing action into guide rail clamping force and inner clamping frame positioning force. The tightening blocks on both sides of the sliding rod form a double locking structure, reducing adjustment time by more than 50% compared to traditional fixtures and improving operational flexibility. The modular adjustable design allows a single fixture to replace the functions of multiple dedicated fixtures, reducing procurement and inventory pressure. The integrated structure, combined with the anti-interference design, extends equipment life by more than 30%. Improved versatility reduces storage volume by more than 60%, simplifies management ledgers, and reduces overall costs. Attached Figure Description

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a technical solution: a multi-pin synchronous solder wrapping fixture, comprising: Fixture shell 1; The large-area fixing component 2 includes an inner slide plate 215 slidably connected within the fixture housing 1. A triangular block 216 is slidably connected to the inner slide plate 215 via a fixed shaft 210. A side frame 212 and the triangular block 216 are fixedly connected to the triangular block 216. A fixed rod 27 is fixedly connected to the bottom of the inner slide plate 215. A piston plate 26 is slidably connected to the fixed rod 27. A fixed frame 25 is slidably connected to the piston plate 26. The fixed frame 25 is fixedly connected within the fixture housing 1. A transmission block 28 is slidably connected to the inner slide plate 215. A guide frame 214 is fixedly connected to the transmission block 28 via an extension rod 213. A guide rail 21 is slidably connected to the guide frame 214. A pin insertion port 22 is slidably connected to the guide rail 21. An opening 23 is provided on the guide rail 21.

[0024] like Figures 1 to 5 As shown, when the inner slide plate 215 is pressed, the fixed shaft 210 slides in the inclined hole of the triangular block 216, causing the triangular block 216 to move. This, in turn, drives the transmission shaft 217 to slide in the inclined hole of the transmission block 28 via the transmission plate 211. This causes the transmission block 28 to drive the guide frame 214 and the guide rail 21 to slide down synchronously via the extension rod 213, thus clamping the pins. At the same time, the inner clamping frame 291 slides along the inner groove of the fixture shell 1 with the side frame 212, gradually contacting the workpiece to complete the positioning. Based on this transmission logic, the fixture constructs a three-level adjustable adaptation system: the pin insertion port 22 slides along the guide rail 21 and is locked by the screw in the opening 23, which can match different pin spacings. The guide rail 21, combined with the inclined hole transmission, realizes... The overall position adjustment adapts to different pin numbers, and the inner clamping frame 291 is fixed with multi-position bolts, compatible with different sized workpieces, greatly reducing the need for special fixtures. The innovative oblique hole transmission mechanism transforms the single operation of the inner slide plate 215 into the synchronous output of the clamping force of the guide rail 21 and the positioning force of the inner clamping frame 291. Combined with the double locking structure of the tightening blocks 3 on both sides of the sliding rod 24, the adjustment time is reduced by more than 50% compared with traditional fixtures, improving operational flexibility and reducing procurement and inventory pressure. The integrated structure, combined with the anti-interference design of the opening 23 of the fixture shell 1, extends the equipment life by more than 30%. The improved versatility reduces the storage volume by more than 60%, simplifies management ledgers, and reduces overall costs.

[0025] Furthermore, such as Figures 3 to 5 As shown, both the triangular block 216 and the transmission block 28 have oblique holes. The fixed shaft 210 and the transmission shaft 217 are slidably connected in the oblique holes on the triangular block 216 and the transmission block 28, respectively. Both the transmission block 28 and the inner slide plate 215 have through holes. In use, the oblique holes on the triangular block 216 and the transmission block 28 facilitate the sliding of the fixed shaft 210 and the transmission shaft 217, thereby driving the triangular block 216 and the transmission block 28 to move.

[0026] like Figure 1 , Figure 4 As shown, a transverse hole is provided on the guide frame 214, and a sliding rod 24 is slidably connected in the transverse hole of the guide frame 214. A threaded groove is provided on the sliding rod 24, and a tightening block 3 is threadedly connected to the threaded groove of the sliding rod 24. In use, the transverse hole provided on the guide frame 214 facilitates the sliding rod 24 to slide in it. The operator manually tightens the tightening block 3, causing the tightening block 3 to be moved to the side closer to the fixture housing 1 and locked on the fixture housing 1, thereby fixing the guide frame 214. Tightening blocks 3 are fixed on both sides of the sliding rod 24.

[0027] like Figures 2 to 4 As shown, an extension plate 29 is connected inside the fixture housing 1. An inner clamping frame 291 is fixedly connected to the extension plate 29. A side frame 212 is fixedly connected to the inner clamping frame 291. A transmission plate 211 is fixedly connected to the side frame 212. A transmission shaft 217 is fixedly connected to the transmission plate 211. The transmission shaft 217 is slidably connected inside the transmission block 28. An inner groove is opened inside the fixture housing 1. Both the upper and lower ends of the side frame 212 are slidably connected to the inner groove of the fixture housing 1. In use, the inner clamping frame 291 is fixedly connected to the extension plate 29. The side frame 212 facilitates the transmission plate 211 to drive the transmission shaft 217 to move. When the inner clamping frame 291 is driven to slide inward, the transmission plate 211 will be driven to move synchronously.

[0028] like Figures 4 to 5 As shown, a slot is provided on the inner slide plate 215, and the fixed shaft 210 is fixedly connected to the slot on the inner slide plate 215. By providing a slot on the inner slide plate 215, the triangular block 216 is embedded in the slot and will be moved together.

[0029] like Figures 1 to 2 As shown, the fixture housing 1 has an opening 23, and the extension rod 213 is slidably connected in the opening 23 on the fixture housing 1. By having an opening 23 on the fixture housing 1, the extension rod 213 slides vertically in the opening 23 on the fixture during use, so as to prevent the extension rod 213 from being blocked and unable to move.

[0030] Working principle: like Figure 1-5As shown, when using it, first place the workpiece to be processed on the inner slide plate 215. The operator manually moves the pin insertion port 22 to slide it on the guide rail 21 so that the position of the pin insertion port 22 corresponds to the position of the pin on the workpiece to be processed. Then, screw a screw into the opening 23 at the position of the pin insertion port 22 to limit and fix the pin insertion port of the workpiece to be processed. Pressing the inner slide plate 215 causes it to slide down the fixture housing 1. The piston plate 26 is pressed into the fixed frame 25, causing the fixed frame 25 to undergo elastic deformation. This causes the fixed shaft 210 to slide in the inclined hole on the triangular block 216, which in turn causes the triangular block 216 to slide towards the side closer to the inner slide plate 215. This displacement of the triangular block 216 causes the transmission plate 211 to move, which in turn causes the transmission plate 211 to move the transmission shaft 217 on the transmission block 28. This causes the transmission block 28 to slide down, which in turn causes the extension rod 213 to slide down, which in turn causes the extension rod 213 to slide down the guide frame 214. This causes the guide rail 21 to slide down and lock the needle. Tightening the tightening block 3 fixes the guide rail 21 on the guide frame 214. During this process, when the inner clamping frame 291 is driven to slide inward, the inner clamping frame 291 gradually contacts the workpiece to be processed. A larger bolt is selected and screwed into the through hole on the fixture housing 1 so that it passes through the fixture housing 1 to fix the inner sliding plate 215, thus completing the fixation of the workpiece to be processed. After the bolts are removed, the piston plate 26 is driven to reset under the action of air pressure on the fixed frame 25.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
