Description

Technical Field

[0001] This utility model belongs to the field of converter upper housing production technology, and in particular relates to a punching tool for the upper housing of a portable converter. Background Technology

[0002] In the early production process of portable converter housings, the clamping and fixing methods for the housings were relatively simple and crude, often using general-purpose simple clamps or manual fixing devices, which often could not provide sufficient stability. During the drilling process, due to the vibration and axial force generated by the rotation of the drill bit, the housing was prone to shaking or displacement, which led to unstable drilling quality, such as hole diameter deviation and substandard hole wall roughness, thus affecting the drilling accuracy and significantly reducing the product yield. Therefore, a drilling fixture for portable converter housings is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling fixture for the upper shell of a portable converter. By setting up a clamping assembly, specifically, a motor drives a gear 1 to rotate via a gear 1. When the gear 2 rotates, it drives a number of connecting rods through several arc-shaped grooves. The connecting rods, through several straight grooves, drive several fixing plates to move closer together. At the same time, the clamping plates clamp the shell by moving closer together through the fixing plates. At this time, the clamping plates under force compress the spring, and the spring generates a certain rebound force, which drives the clamping plates to clamp and fix the shell. This solves the problem that during the drilling process, the shell is prone to shaking or displacement due to the vibration and axial force generated by the rotation of the drill bit, which leads to unstable drilling quality, such as hole diameter deviation and substandard hole wall roughness, thus affecting the drilling accuracy and significantly reducing the product yield.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a punching fixture for the upper shell of a portable converter, comprising a main frame mechanism. The main frame mechanism includes a working base, a clamping assembly on the top of the working base, an adjusting assembly on the top of the clamping assembly, and a supporting frame. The clamping assembly includes a turntable, the top of which has several fixed plates, each with a clamping plate on its corresponding side. Several straight grooves are formed inside the turntable and on the top of the working base. A second gear is located at the bottom of the working base, with an arc-shaped groove inside. A first gear is meshed with the outer surface of the second gear. A first motor is located to the right of the second gear, and a motor bracket is fixedly connected to the outer surface of the first motor. The top of the motor bracket is fixedly connected to the bottom of the working base. The top output end of motor one is fixedly connected to the inside of gear one via a coupling. A rotating rod is fixedly connected inside gear two. The rotating rod passes through the working base and extends to the top. The inside of the turntable is rotatably connected to the outer surface of the rotating rod. A number of connecting rods are provided inside each of the arc-shaped grooves. A number of connecting rods pass through the working base and extend to the top of the turntable. A number of fixed plates are fixedly connected to the outer surface of the connecting rods. The outer surface of the connecting rods contacts the inner wall of the straight groove. When motor one is started, gear one drives gear two to rotate. When gear two rotates, it drives a number of connecting rods to move through the arc-shaped grooves. The connecting rods, through the action of the straight grooves, drive the fixed plates to move closer to each other. At the same time, the clamping plates, through the movement of the fixed plates, clamp the housing.

[0006] Furthermore, each of the fixed plates is slidably connected to a sliding rod, and each of the sliding rods is fitted with a spring on its outer surface. The side of each spring away from the fixed plate is fixedly connected to the side of the clamping plate away from each other, and the side of each spring away from the clamping plate is fixedly connected to the side of the fixed plate close to each other. The clamping plate under force will compress the spring, and at the same time, the spring will generate a certain rebound force and drive the clamping plate to clamp and fix the shell, avoiding the shell from shaking under force during the drilling process, greatly improving the drilling accuracy, and can clamp shells of different shapes.

[0007] Furthermore, a protective ring is fixedly connected to the top of the working base, and the inner wall of the protective ring is fixedly connected to the outer ring of the turntable. A drilling device is provided on the top of the turntable, and a movable frame is fixedly connected to the top of the drilling device. A cavity is opened on the front of the support frame, and the outer surface of the movable frame is slidably connected to the inside of the cavity. A second motor is fixedly connected to the right side of the working base, and a threaded rod is rotatably connected to the back of the inside of the working base. An opening is opened on the back of the top of the working base, and the bottom of the outer surface of the support frame contacts the inner wall of the opening. An opening is opened on the back of the working base, and the back of the outer surface of the support frame contacts the inner wall of the opening. When the second motor is started, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the support frame to move. At the same time, when the support frame moves, it moves inside the opening.

[0008] Furthermore, the bottom of the inside of the support frame is threadedly connected to the outer surface of the threaded rod, and the back of the inside of the support frame is slidably connected to the outer surface of the support rod. Limiting blocks are fixedly connected to the left and right sides of the back of the working base. The inside of the two limiting blocks is fixedly connected to the left and right sides of the outer surface of the support rod. The back of the inside of the support frame will slide on the outer surface of the support rod. The support rod provides a certain stability for the movement trajectory of the support frame. When the support frame moves, it will drive the drilling device to move through the action of the moving frame, thereby adjusting the left and right position of the drilling device.

[0009] Furthermore, an electric push rod is fixedly connected to the back of the support frame, and a telescopic rod is slidably connected to the top inside the support frame. The front output end of the electric push rod is fixedly connected to the back of the telescopic rod, and the side of the telescopic rod away from the electric push rod is fixedly connected to the back of the moving frame. When the electric push rod is activated, it drives the telescopic rod to move. When the telescopic rod moves, it drives the moving frame to move. Similarly, when the moving frame moves, it drives the drilling device to move, thereby adjusting the front and rear position of the drilling device.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, through the setting of a clamping assembly, specifically, starts a motor that drives a gear two to rotate via a gear one. When the gear two rotates, it drives a number of connecting rods through several arc-shaped grooves. These connecting rods, through the action of several straight grooves, drive several fixed plates to move closer together. At the same time, the clamping plates clamp the housing by moving closer together through the fixed plates. At this time, the clamping plates under force compress the spring, and the spring generates a certain rebound force, which drives the clamping plates to clamp and fix the housing, preventing the housing from shaking under force during the drilling process. This greatly improves the drilling accuracy and can clamp housings of different shapes, significantly improving the versatility of the equipment. Precise drilling greatly improves the product yield.

[0012] 2. This utility model incorporates an adjustment mechanism. Specifically, a second motor drives a support frame via a threaded rod. When the support frame moves, it moves the drilling device through a movable frame, thereby adjusting the left-right position of the drilling device. Simultaneously, an electric push rod can be activated to move the movable frame via a telescopic rod. Similarly, the movable frame's movement moves the drilling device, adjusting its front-back position. The drilling device's position can be adjusted omnidirectionally to accommodate the drilling requirements of different converter housing models, thus further improving drilling quality and significantly enhancing the device's flexibility.

[0029] A specific application of this embodiment is as follows: In use, the housing is first placed on top of the turntable 211, and simultaneously placed between four turntables 211. Then, motor one 212 is started to drive gear one 214 to rotate. At the same time, motor bracket 213 provides a certain support force for motor one 212 through its fixed connection with the working base 111. When gear one 214 rotates, it drives gear two 215 to rotate. When gear two 215 rotates, it drives several connecting rods 217 to move through several arc-shaped grooves 216. The several connecting rods 217 will move closer to each other through the action of several straight grooves 219. When the several connecting rods 217 move closer to each other, they will drive... Several fixed plates 220 approach each other, and several clamping plates 221 clamp the shell by approaching each other through the fixed plates 220. When the clamping plates 221 clamp the shell, due to the irregular shape of the shell, the clamping plates 221 under force will move closer to the fixed plates 220. At the same time, the clamping plates 221 will drive the sliding rod 222 to slide inside the fixed plates 220. When the clamping plates 221 move, they will compress the spring 223. The spring 223 will contract and store force due to the limiting effect of the fixed plates 220. At the same time, the spring 223 will generate a certain rebound force and drive the clamping plates 221 to reset. When the clamping plates 221 reset, they will clamp the shell. The device is fixed in place to prevent the housing from shaking during drilling, significantly improving drilling accuracy. It can also clamp housings of different shapes, greatly enhancing the equipment's versatility. Precise drilling significantly improves product yield. During drilling, motor 311 can be activated to rotate the threaded rod 314. The rotation of the threaded rod 314 drives the support frame 312 to move. Simultaneously, the support frame 312 moves within the opening 315, and its inner back surface slides on the outer surface of the support rod 318. The support rod 318 provides a certain range for the movement trajectory of the support frame 312. For stability, when the support frame 312 moves, it drives the drilling device 114 to move through the moving frame 113, thereby adjusting the left and right position of the drilling device 114. At the same time, the operator can also activate the electric push rod 313 to drive the telescopic rod 319 to move. When the telescopic rod 319 moves, it drives the moving frame 113 to move. Similarly, when the moving frame 113 moves, it drives the drilling device 114 to move, thereby adjusting the front and back position of the drilling device 114. The position of the drilling device 114 can be adjusted in all directions to meet the drilling requirements of the upper shell of different models of converters, thereby further improving the drilling quality and greatly enhancing the flexibility of the equipment.
