Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an assembly and welding mold for sheet metal processing. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. They are characterized by their light weight, high strength, electrical conductivity, low cost, and good mass production performance. They are widely used in fields such as electronics, communications, automotive, and medical devices. When assembling and welding sheet metal parts, high-reliability assembly and welding molds are now commonly used. In practice, these molds offer advantages such as simple operation, precise welding, and stable use.

[0003] A relevant reference is Chinese utility model patent CN222843424U, which discloses an assembly and welding mold for sheet metal processing. It includes a work panel, with a set of movable electric guide rails on each of the opposite side walls. Two sets of drive components are symmetrically arranged at one end of the work panel. A unidirectional threaded rod and an electric telescopic rod are located above the work panel. A clamping assembly is also located above the work panel, with a limiting groove at the bottom center of the clamping assembly. A bidirectional threaded rod is located inside the clamping assembly. Two sets of clamping panels are located at the bottom of the clamping assembly. A mold groove is formed at the center of the surface of the work panel. An electric push rod is located inside each of the two limiting grooves. Two sets of limiting rectangular plates are located inside the mold groove. This embodiment can clamp molds of different specifications, improving the practicality of the equipment.

[0004] The aforementioned assembly and welding mold limits the sheet metal parts during welding by clamping, and then adjusts the position by electric push rod. During use, the edges of the sheet metal parts may form angles and fail to fit completely. In this case, the clamping mechanism needs to be loosened and adjusted again, which is very inconvenient. At the same time, it cannot quickly limit the angle of the sheet metal parts when adjusting the angle, and cannot meet the welding requirements of different angles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an assembly and welding mold for sheet metal processing, which solves the problems of not being able to make fine adjustments after fixing and not being able to quickly adjust the angle between sheet metal parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly and welding mold for sheet metal processing includes a support frame, and a limit mechanism is provided above the support frame.

[0007] The support assembly includes a fixed frame fixedly installed on the upper end of the support frame, a movable frame movably installed on one side of the fixed frame, a rubber tube fixedly installed inside the fixed frame, a dual-axis motor fixedly installed inside the movable frame, lead screws fixedly installed at both ends of the dual-axis motor, a limit frame movably installed on the outer side of the lead screws, and a movable column inserted through the center of the limit frame.

[0008] An adsorption component is positioned above the support component to limit the position of the sheet metal parts.

[0009] Preferably, the adsorption assembly includes electric push rods fixedly installed on the left and right sides of the bottom of the fixed frame and the movable frame. A slider is fixedly installed at the end of the electric push rod. A movable plate is movably installed above the slider. A limit bolt is fitted on the top of the movable plate. A rubber gasket is fitted inside the movable plate. A pneumatic suction cup is inserted on the top of the movable plate.

[0010] Preferably, the slider is symmetrically installed on the left and right sides of the fixed frame and the movable frame, and the slider is slidably connected to both the fixed frame and the movable frame. The movable plate is provided with stepped groove structures on both sides.

[0011] Preferably, the limiting bolt passes through the bottom end of the movable plate and connects to the slider, the inner side of the rubber gasket contacts the cylindrical protrusion structure at the upper end of the slider, and the pneumatic suction cup is fixedly installed at the center and four corners of the movable plate.

[0012] Preferably, the fixed frame and the movable frame are rotatably connected by bearings. The inner rear end of the fixed frame is provided with symmetrical cylindrical protrusions, and the interior of the cylindrical protrusions is provided with cylindrical cavities that match the outer diameter of the rubber tube. The diameter of the front end of the cylindrical cavity of the fixed frame is smaller than the inner diameter of the cavity. The rubber tubes are symmetrically installed inside the cylindrical structures on the left and right sides of the rear end of the fixed frame.

[0013] Preferably, the lead screw is rotatably connected to the limiting frame via a bearing, the limiting frame is fixedly connected to the movable frame, the front end of the movable column is provided with a disc-shaped protrusion with a diameter larger than the inner diameter of the rubber tube, and the front end of the disc-shaped protrusion is provided with a chamfered structure, and the inner side of the rear end of the movable column is provided with a groove that fits into the threaded structure of the lead screw.

[0014] Beneficial effects

[0015] This utility model provides an assembly and welding mold for sheet metal processing. Compared with the prior art, it has the following advantages:

[0016] (1) The assembly and welding mold for sheet metal processing is equipped with a dual-axis motor. Pressing and holding the button on the back of the movable frame starts the dual-axis motor. The dual-axis motor rotates and drives the lead screw to rotate. Because the lead screw is threaded into the groove on the inner side of the rear end of the movable column, the rotation of the lead screw drives the movable column to move towards the dual-axis motor, so that the end of the movable column is pulled out from the inside of the rubber tube. The damping between the movable frame and the fixed frame approaches zero, and the adjustable angle state is entered. At this time, the movable frame can be rotated to adjust the angle between it and the fixed frame, thereby changing the welding angle of the sheet metal part above to meet the welding requirements. After the angle is adjusted, the button is released, and the dual-axis motor drives the lead screw to rotate in the opposite direction, driving the movable column to move to both sides to reset. The end of the movable column is inserted back into the inside of the rubber tube. The disc-shaped protrusion at the end of the movable column squeezes the rubber tube, increasing the friction between the two to form rotational damping, limiting the angle between the movable frame and the fixed frame, and completing the angle locking. The dual-axis motor is controlled by the button to realize the damping switching and angle adjustment. There is no need for complicated manual disassembly and debugging. It is easy for workers to learn and saves operation time.

[0017] (2) The assembly and welding mold used for sheet metal processing, through the setting of the movable plate, the two sheet metal parts are respectively restricted above the movable plate above the fixed frame and the movable frame by suction cups. Since the end of the electric push rod is connected to the slider, the slider and the movable frame form a sliding connection. The change of the extension of the electric push rod will drive the slider position to change, thereby changing the relative position of the two sides of the movable plate, realizing the adjustment of the tilt angle of the movable plate until the two sheet metal parts are welded in a parallel state. After adjusting the tilt angle of the movable plate to make the welding point parallel, the movable plate is pushed so that the welding position of the two sheet metal parts can be completely overlapped when they are attached. The extension of the electric push rods on both sides of the movable plate is adjusted to correct the position of the movable plate after the tilt angle is adjusted, ensuring that the welding point of the two sheet metal parts can be in contact, preparing for welding, so that the angle of the sheet metal parts can be adjusted after fixing the sheet metal parts.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: an assembly and welding mold for sheet metal processing, including a support frame 1, and a limit mechanism 2 is provided above the support frame 1.

[0026] The support assembly 21 includes a fixed frame 211 fixedly mounted on the upper end of the support frame 1, a movable frame 212 movably mounted on one side of the fixed frame 211, a rubber tube 213 fixedly mounted inside the fixed frame 211, a dual-axis motor 214 fixedly mounted inside the movable frame 212, lead screws 215 fixedly mounted at both ends of the dual-axis motor 214, a limit frame 216 movably mounted on the outer side of the lead screws 215, a movable column 217 inserted through the center of the limit frame 216, a rotatable connection between the fixed frame 211 and the movable frame 212 via bearings, and a symmetrical cylindrical protrusion provided on the inner rear end of the fixed frame 211. The cylindrical protrusion has a cylindrical cavity inside that matches the outer diameter of the rubber tube 213. The diameter of the front end of the cylindrical cavity of the fixing frame 211 is smaller than the inner diameter of the cavity. The rubber tube 213 is symmetrically installed on the left and right sides of the cylindrical structure at the rear end of the fixing frame 211. The lead screw 215 is rotatably connected to the limit frame 216 through the bearing. The limit frame 216 is fixedly connected to the movable frame 212. The front end of the movable column 217 has a disc-shaped protrusion with a diameter larger than the inner diameter of the rubber tube 213, and the front end of the disc-shaped protrusion has a chamfered structure. The inner side of the rear end of the movable column 217 has a groove that fits into the threaded structure of the lead screw 215.

[0027] Specifically, a counterweight is fixedly installed at the center of the support frame 1 to prevent the support frame 1 from tipping over due to the weight of the sheet metal parts above the movable frame 212. The fixed frame 211 can limit the position of the movable frame 212. The movable frame 212 can rotate to adjust the angle between itself and the fixed frame 211. A button is provided on the rear side of the movable frame 212 to control the start and stop of the dual-axis motor 214. The initial position of the movable column 217 is located at the end of the lead screw 215. The end of the movable column 217 is located inside the rubber tube 213. The disc-shaped structure at the end of the movable column 217 squeezes the rubber tube 213 to increase the friction between the movable column 217 and the rubber tube 213, thereby increasing the rotational damping and limiting the movement of the movable frame 212. When the button is pressed and held, the included angle between the fixed brackets 211 will drive the dual-axis motor 214 to rotate. The dual-axis motor 214 drives the lead screw 215 to rotate, causing the lead screw 215 to move towards the dual-axis motor 214. This causes the end of the movable column 217 to be pulled out of the rubber tube 213. At this time, the damping between the movable bracket 212 and the fixed bracket 211 approaches zero, which facilitates the adjustment of the included angle between the two sheet metal parts. After the angle is fully adjusted, releasing the button will cause the dual-axis motor 214 to drive the lead screw 215 to rotate, causing the movable column 217 to move to both sides until the movable column 217 returns to its original position, with its end inserted into the rubber tube 213 to limit the included angle between the movable bracket 212 and the fixed bracket 211.

[0028] The adsorption assembly 22, positioned above the support assembly 21, is used to limit the position of the sheet metal part. The adsorption assembly 22 includes electric actuators 221 fixedly installed on the left and right sides of the bottom of the fixed frame 211 and the movable frame 212. A slider 222 is fixedly installed at the end of each electric actuator 221. A movable plate 223 is movably installed above the slider 222. A limit bolt 224 is fitted onto the top of the movable plate 223. A rubber gasket 225 is fitted inside the movable plate 223. A [missing information - likely a device or component] is inserted through the top of the movable plate 223. The pneumatic suction cup 226 and the slider 222 are symmetrically installed on the left and right sides of the fixed frame 211 and the movable frame 212, and the slider 222 is slidably connected to both the fixed frame 211 and the movable frame 212. The movable plate 223 has stepped groove structures on both sides. The limiting bolt 224 passes through the bottom end of the movable plate 223 and connects to the slider 222. The inner side of the rubber gasket 225 contacts the cylindrical protrusion structure at the upper end of the slider 222. The pneumatic suction cup 226 is fixedly installed at the center and four corners of the movable plate 223.

[0029] Specifically, the electric actuator 221 can adjust the position of the slider 222 to adjust the distance between the two sheet metal parts above the fixed frame 211 and the movable frame 212. The limiting bolt 224 above the slider 222 inside the fixed frame 211 remains tightened, and the movable plate 223 above the fixed frame 211 will be secured by the limiting bolt 224 and cannot move. When an angle appears between the weld seam between the sheet metal part above the movable frame 212 and the sheet metal part above the fixed frame 211, the extension of the electric actuator 221 on one side of the movable frame 212 can be adjusted. The tilt angle of the movable plate 223 is adjusted to ensure that the two sheet metal parts are welded in a parallel state. At the same time, the extension of the electric push rods 221 on both sides of the movable plate 223 is adjusted to correct the position of the movable plate 223 after the tilt angle is adjusted, so as to ensure that the weld joint of the two sheet metal parts can be in contact after the angle is adjusted. Meanwhile, the rubber gasket 225 fixedly installed on the inner side of the slide groove of the movable plate 223 can increase the sliding damping of the movable plate 223 to prevent the movable plate 223 from sliding during the welding process and affecting the relative position between the sheet metal parts.

[0030] Specifically, the dual-axis motor 214 is model number 1020-0631051-5, the electric actuator 221 is model number FD5, and the pneumatic suction cup 226 generates a vacuum after airflow is introduced by its built-in vacuum generator. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] During operation, press and hold the button on the rear of the movable frame 212. This operation starts the dual-axis motor 214, which drives the lead screw 215 to rotate. Because the lead screw 215 is threaded into the inner groove at the rear end of the movable column 217, the rotation of the lead screw 215 moves the movable column 217 towards the dual-axis motor 214, causing the end of the movable column 217 to be pulled out from inside the rubber tube 213. The damping between the movable frame 212 and the fixed frame 211 approaches zero, entering an adjustable angle state. At this time, the movable frame 212 can be rotated. 12. Adjust the angle between the movable frame 212 and the fixed frame 211 to change the welding angle of the upper sheet metal part to meet welding requirements. After the angle adjustment is completed, release the button. The dual-axis motor 214 drives the lead screw 215 to rotate in the opposite direction, causing the movable column 217 to move to both sides to reset. The end of the movable column 217 is inserted back into the rubber tube 213. The disc-shaped protrusion at the end of the movable column 217 squeezes the rubber tube 213, increasing the friction between the two and forming rotational damping, thus limiting the angle between the movable frame 212 and the fixed frame 211, completing the angle locking. The dual-axis motor 214 is controlled by a button to switch damping and adjust angles, eliminating the need for complex manual disassembly and adjustment. This makes it easy for workers to use and saves operating time. The two sheet metal parts are respectively held above the movable plate 223 above the fixed frame 211 and the movable frame 212 by suction cups. Since the end of the electric actuator 221 is connected to the slider 222, the slider 222 and the movable frame 212 form a sliding connection. Changes in the extension of the electric actuator 221 will cause changes in the position of the slider 222, thereby changing the relative position of the two sides of the movable plate 223. The tilt angle of the movable plate 223 is adjusted until the two sheet metal parts are welded in a parallel state. After adjusting the tilt angle of the movable plate 223 to make the weld joint parallel, the movable plate 223 is pushed so that the weld positions of the two sheet metal parts can be completely overlapped when they are fitted together. The extension of the electric push rods 221 on both sides of the movable plate 223 is adjusted to correct the position of the movable plate 223 after the tilt angle is adjusted, ensuring that the weld joint of the two sheet metal parts can be in contact, in preparation for welding, so that the angle of the sheet metal parts can be adjusted after the sheet metal parts are fixed.
