Description

Technical Field

[0001] This utility model relates to the field of adapter shell processing technology, specifically to an adapter shell punching device that facilitates positioning. Background Technology

[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It generally consists of a casing, transformer, inductor, capacitor, control IC, PCB board, and other components. Its working principle is to convert AC input to DC output. Based on the connection method, it can be divided into wall-mounted and desktop types. It is widely used in security cameras, set-top boxes, routers, LED strips, massagers, and other devices.

[0003] Existing power adapter housing processing equipment leaves sprue at the injection gate after the power adapter housing is injection molded. This sprue can affect the assembly of the entire product. Therefore, it is necessary to perform a punching operation on the adapter housing to clean the burrs on the surface of the adapter housing and punch out the connection hole at the top of the adapter housing for easy installation.

[0004] A search revealed a utility model patent with publication number CN210911012U, which discloses a punching device for injection molding a power adapter housing. The device includes a base and four support legs. Rectangular grooves are formed at both ends of the top outer wall of the base, and lead screws are rotatably connected to the inner walls of both ends of the rectangular grooves. A sliding block is rotatably connected to the outer circumference of the lead screw via a thread, and a baffle is installed on the top outer wall of the sliding block. Stepper motors are installed on the outer walls of both ends of the base, and the output shafts of the stepper motors are fixedly connected to the outer wall of one end of the lead screw via bolts. This utility model, by incorporating a detachable fixing plate, punching column, lower fixing plate, connecting cylinder, and baffle, can accommodate power adapter housings of different models and specifications, thus improving the applicability of the device. The stepper motors, sliding blocks, and lead screws can drive the two baffles to quickly and firmly fix the power adapter housing, improving fixing efficiency and facilitating subsequent punching.

[0005] Although the aforementioned patent uses a stepper motor, sliding block, and lead screw to drive two baffles to quickly and securely fix the power adapter shell, improving fixing efficiency and facilitating subsequent punching, when the punching device punches the burrs on the surface of the adapter shell, the burrs and openings at the top are splashed around the surface of the punching device under the push of the nitrogen spring. The small size of the punched burrs and other debris makes it extremely inconvenient for workers to clean up the debris, and the debris residue will affect the subsequent punching quality.

[0006] Therefore, it is necessary to propose an adapter housing punching device that is easy to position in order to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide an adapter housing punching device that is easy to position. Through the cooperation between the internal parts of the protective mechanism, the punching device body can protect the perimeter of the punching base during punching operations, thus preventing debris from splashing onto the perimeter of the punching device body. The debris is instead splashed between the punching base and the protective plate, making it easier for workers to clean and collect the debris. This solves the problem in the prior art where, when punching burrs on the adapter housing surface, the burrs and openings at the top are splashed onto the perimeter of the punching device under the push of the nitrogen spring. The small size of the burrs and other debris makes it extremely inconvenient for workers to clean the debris, and the debris residue affects the subsequent punching quality.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adapter shell punching device for easy positioning, comprising a punching device body, wherein a punching mechanism is bolted to the top end of the punching device body and extends into the inner cavity of the punching device body, and a protective mechanism is slidably connected to the inner cavity of the punching device body and extends into the interior of the punching device body and is slidably sleeved with the outer wall of the punching mechanism.

[0009] The punching mechanism includes a punching base, which is bolted to the top of the inner cavity of the punching device body. Limiting rods are mechanically connected to both sides of the outer wall of the punching base. A support plate is slidably connected to the top of the punching base and sleeved with the outer wall of the limiting rods. A servo motor is bolted to the top of the punching device body, and a No. 1 threaded rod is fixedly connected to the output end of the servo motor and penetrates into the interior of the punching device body. The support plate is sleeved and slidably connected to the outer wall of the No. 1 threaded rod.

[0010] The protective mechanism includes a waste box, which is slidably connected to one end of the outer wall of the punching device body and extends into the interior of the punching device body. The bottom end of the first threaded rod is mechanically connected to a second threaded rod. A lifting plate is slidably connected inside the punching device body and sleeved with the outer wall of the second threaded rod. The end of the lifting plate away from the second threaded rod is mechanically connected to a protective plate and slidably connected to the inner cavity of the punching device body. A discharge port is provided between the inner wall of the protective plate and the inner wall of the punching device body, and the discharge port is located on both sides of the top of the waste box.

[0011] Preferably, the punching mechanism further includes positioning rods, a plurality of positioning rods being mechanically connected to the bottom end of the support plate and all located at the top end of the punching base. The top end of the support plate is bolted to a punching module and sleeved with the outer wall of the positioning rods. The bottom end of the punching module is mechanically connected to a punching blade, and the top end is equipped with a hydraulic telescopic rod.

[0012] Preferably, the main body of the punching device has a sliding groove inside that matches the support plate, and the inner wall of the support plate has an internal thread that matches the thread on the outer wall of the first threaded rod. A hydraulic pump for driving the punching module is installed and fixed at the top of the main body of the punching device.

[0013] Preferably, the surface of the support plate is provided with a limiting hole that matches the limiting rod, and the bottom end of the positioning rod is connected to a rubber buffer layer that contacts and presses against the top end of the punching base.

[0014] Preferably, the outer wall thread direction of the No. 2 thread rod is opposite to the outer wall thread direction of the No. 1 thread rod, and the main body of the punching device has a lifting groove inside that matches the lifting plate and the protective plate. The inner wall of the lifting plate has a thread groove that matches the outer wall thread of the No. 2 thread rod.

[0015] Preferably, the top of the protective plate is provided with an inclined chamfer, the inner cavity of the punching device body is provided with a conical surface and located on both sides above the protective plate, and the top of the waste box is connected to the bottom of the discharge port.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By placing the adapter housing on the punching base, the servo motor is started. The servo motor drives the first threaded rod to rotate. The rotation of the first threaded rod causes the support plate to move downward. The support plate moves stably on the main body of the punching device through the limit rod, so that the support plate drives the punching module to move above the punching base. At the same time, the positioning rod at the bottom of the support plate first contacts the adapter housing. The rubber buffer layer connected to the bottom of the positioning rod contacts and presses against the top of the punching base, thus completing the positioning and clamping of the adapter housing on the punching base. This improves the stability of the punching module during punching and improves the punching quality of the adapter housing.

[0018] 2. The servo motor drives the first threaded rod to rotate, which in turn drives the second threaded rod to rotate. The second threaded rod then moves the lifting plate upward, allowing the lifting plate to move the protective plate out of the main body of the punching device, thus protecting the punching base. After the punching module completes the punching, the debris generated during punching is retained between the protective plate and the punching base. The servo motor rotates in the opposite direction, causing the second threaded rod to rotate in the opposite direction, which in turn moves the lifting plate. This moves the protective plate from the top of the punching device to the inside of the main body, removing the protection of the punching base. The debris between the protective plate and the punching base then falls through the conical surface and chamfer into the discharge port, and then into the waste box. This completes the collection of debris, reducing debris splashing on the surface of the punching device and affecting the punching quality. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The adapter housing punching device shown includes a punching device body 1, a punching mechanism 2 is bolted to the top of the punching device body 1 and extends into the inner cavity of the punching device body 1, and a protective mechanism 3 is slidably connected to the inner cavity of the punching device body 1 and extends into the interior of the punching device body 1 and is slidably sleeved with the outer wall of the punching mechanism 2.

[0029] The punching mechanism 2 includes a punching base 201, which is bolted to the top of the inner cavity of the punching device body 1. Limiting rods 202 are mechanically connected to both sides of the outer wall of the punching base 201. A support plate 203 is slidably connected to the top of the punching base 201 and sleeved with the outer wall of the limiting rods 202. A servo motor 206 is bolted to the top of the punching device body 1, and a first threaded rod 207 is fixedly connected to the output end of the servo motor 206 and penetrates into the interior of the punching device body 1. The support plate 203 is sleeved and slidably connected to the outer wall of the first threaded rod 207.

[0030] The protective mechanism 3 includes a waste box 301, which is slidably connected to one end of the outer wall of the punching device body 1 and extends into the interior of the punching device body 1. The bottom end of the first threaded rod 207 is mechanically connected to the second threaded rod 302. The interior of the punching device body 1 is slidably connected to a lifting plate 303, which is sleeved with the outer wall of the second threaded rod 302. The end of the lifting plate 303 away from the second threaded rod 302 is mechanically connected to a protective plate 304, which is slidably connected to the inner cavity of the punching device body 1. A discharge port 305 is provided between the inner wall of the protective plate 304 and the inner wall of the punching device body 1, and the discharge port 305 is located on both sides of the top of the waste box 301.

[0031] The cooperation between the internal parts of the punching mechanism 2 facilitates the positioning and clamping of the adapter housing and the punching base 201 when the punching device body 1 punches the adapter housing, preventing the adapter housing from shifting during the punching process. The cooperation between the internal parts of the protective mechanism 3 facilitates the protection of the punching base 201 around the punching device body 1 during the punching operation, preventing debris from splashing around the surface of the punching device body 1. The debris is then splashed between the punching base 201 and the protective plate 304, making it easier for workers to clean and collect the debris.

[0032] Refer to the instruction manual appendix Figure 1-5 The punching mechanism 2 also includes positioning rods 204. Multiple positioning rods 204 are mechanically connected to the bottom end of the support plate 203 and are all located at the top end of the punching base 201. The top end of the support plate 203 is bolted to the punching module 205 and sleeved with the outer wall of the positioning rods 204. The bottom end of the punching module 205 is mechanically connected to the punching blade and the top end is equipped with a hydraulic telescopic rod. Through the mutual cooperation between the internal parts of the punching mechanism 2, when the punching module 205 and the adapter shell on the punching base 201 approach each other, the positioning rods 204 first contact the top end of the adapter shell to complete the positioning and clamping of the adapter shell on the punching base 201.

[0033] Refer to the instruction manual appendix Figure 1-5The punching device body 1 has a sliding groove inside that matches the support plate 203, and the inner wall of the support plate 203 has an internal thread that matches the outer thread of the first threaded rod 207. The top of the punching device body 1 is equipped with a hydraulic pump that drives the punching module 205 to punch. The sliding groove inside the punching device body 1 matches the support plate 203, and the inner wall of the support plate 203 has an internal thread that matches the outer thread of the first threaded rod 207, so that the first threaded rod 207 can rotate to drive the support plate 203 to slide on the outer wall of the punching device body 1.

[0034] Refer to the instruction manual appendix Figure 1-5 The surface of the support plate 203 is provided with a limiting hole that matches the limiting rod 202, and the bottom end of the positioning rod 204 is connected to a rubber buffer layer that contacts and presses against the top end of the punching base 201. The limiting hole provided on the surface of the support plate 203 matches the limiting rod 202, and the bottom end of the positioning rod 204 is connected to a rubber buffer layer that contacts and presses against the top end of the punching base 201, which facilitates the sliding of the support plate 203 by the limiting rod 202 and improves the stability of the support plate 203 driving the punching module 205 to slide.

[0035] Refer to the instruction manual appendix Figure 1-5 The outer wall thread direction of the second thread rod 302 is opposite to the outer wall thread direction of the first thread rod 207. The main body 1 of the punching device has a lifting groove that matches the lifting plate 303 and the protective plate 304. The inner wall of the lifting plate 303 has a thread groove that matches the outer wall thread of the second thread rod 302. Since the outer wall thread direction of the second thread rod 302 is opposite to the outer wall thread direction of the first thread rod 207, and the main body 1 of the punching device has a lifting groove that matches the lifting plate 303 and the protective plate 304, it is convenient for the second thread rod 302 to rotate and drive the lifting plate 303 and the punching module 205 to move towards each other.

[0036] Refer to the instruction manual appendix Figure 1-5 The top of the protective plate 304 is provided with an inclined chamfer. The inner cavity of the punching device body 1 is provided with a conical surface, which is located on both sides above the protective plate 304. The top of the waste box 301 is connected to the bottom of the discharge port 305. The inclined chamfer at the top of the protective plate 304 and the conical surface in the inner cavity of the punching device body 1, located on both sides above the protective plate 304, facilitate the falling of the debris generated by the punching of the punching device body 1 into the protective plate 304 through the conical surface, and into the waste box 301 through the protective plate 304 and the discharge port 305, thus completing the waste collection.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-5By placing the adapter housing on the punching base 201, the servo motor 206 is started. The servo motor 206 drives the first threaded rod 207 to rotate. The rotation of the first threaded rod 207 causes the support plate 203 to move downward. The support plate 203 moves stably on the punching device body 1 through the limit rod 202, so that the support plate 203 drives the punching module 205 to move above the punching base 201. At the same time, the positioning rod 204 at the bottom of the support plate 203 first contacts the adapter housing. The rubber buffer layer connected to the bottom of the positioning rod 204 contacts and presses against the top of the punching base 201, thus completing the positioning and clamping of the adapter housing on the punching base 201. This improves the stability of the punching module 205 during punching and improves the punching quality of the adapter housing.

[0039] Refer to the instruction manual appendix Figure 1-5 The servo motor 206 drives the first threaded rod 207 to rotate, which in turn drives the second threaded rod 302 to rotate. This rotation of the second threaded rod 302 causes the lifting plate 303 to move upwards, allowing the lifting plate 303 to move the protective plate 304 out of the punching device body 1, thus protecting the punching base 201. After the punching module 205 completes the punching, the debris generated is retained between the protective plate 304 and the punching base 201 by the servo motor. 206 rotates in the opposite direction, causing the second threaded rod 302 to rotate in the opposite direction, which in turn moves the lifting plate 303, causing the protective plate 304 to move from the top of the punching device body 1 to the inside of the punching device body 1. After the protection of the punching base 201 is removed, the debris between the protective plate 304 and the punching base 201 falls into the discharge port 305 through the conical surface and chamfer, and then falls into the waste box 301 through the discharge port 305. This completes the collection of debris and reduces the amount of debris splashed on the surface of the punching device body 1, which affects the punching quality.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
