Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a punching device for producing a tricycle frame. Background Art

[0002] The tricycle frame is the core structural component of the tricycle. It supports and connects all the main components of the vehicle, including the engine, wheels, seats, cargo box, etc. The frame is usually made of strong metal materials such as steel or aluminum alloy to ensure sufficient strength and durability to withstand the weight of the vehicle and its load, as well as the various forces and vibrations generated during driving.

[0003] However, nowadays, in order to connect the tricycle frame with other tricycle parts, a punching device is often used to punch the tricycle frame. However, in the current punching operation of the tricycle frame, the traditional punching device relies on manual hand-held fixing of the frame. The operator needs to hold the frame with one hand to prevent movement and operate the joystick with the other hand to punch. This punching method is unstable and easily causes the punched holes to be of different sizes. Moreover, after punching one position, the tricycle frame needs to be manually moved to the next punching position. The work intensity is relatively high, resulting in low punching efficiency. Therefore, it is urgent to develop a stable and efficient punching device for tricycle frame production to make up for the defects of the existing tricycle frame punching operation. Utility Model Content

[0004] In order to overcome the shortcomings of the existing tricycle frame punching method, which has poor punching stability and low efficiency, the technical problem to be solved is to provide a stable punching device for tricycle frame production with high punching efficiency.

[0005] The technical solution is: a punching device for the production of tricycle frames, including a punching machine, a base plate, a T-block, a rack, a mounting frame, a servo motor, a gear and a fixing mechanism. A slide groove is provided on the top right side of the punching machine, a mounting frame is provided on the upper left side of the punching machine, a T-block is fixedly connected to the right rear side of the bottom of the base plate, the T-block is slidably connected to the slide groove, so that the base plate is slidably set on the punching machine, a rack is fixedly connected to the left side of the bottom of the base plate, a servo motor is installed on the mounting frame, the servo motor output shaft is connected to a gear, the gear is meshed with the rack, a fixing mechanism is provided on the top of the base plate, and the fixing mechanism is used to fix the position of the tricycle frame.

[0006] Furthermore, the fixing mechanism includes a positioning plate, a bracket, an extrusion plate and a return spring. The rear and right sides of the top of the base plate are connected to the positioning plates by bolts. The two positioning plates are perpendicular to each other. A bracket is installed on the middle part of the rear positioning plate. The lower part of the bracket is slidably connected to the extrusion plate. A return spring is connected between the bracket and the extrusion plate.

[0007] Furthermore, it also includes rollers. The bottom of the extrusion plate is evenly rotated and connected with six rollers. The rollers can reduce the friction between the extrusion plate and the tricycle frame to prevent the surface from being scratched when the tricycle frame is placed or taken out.

[0008] Furthermore, the invention also comprises a placing rack, on the front side of the punching machine, the placing rack can be used to place the punched tricycle frames, so as to facilitate people to sort and punch the tricycle frames.

[0009] Furthermore, it also includes foam pads. Both positioning plates are provided with foam pads, and the foam pads can protect the surface of the tricycle frame from being scratched by the positioning plates when the tricycle frame moves.

[0010] Furthermore, adjustment holes are provided in a rectangular array on the rear and right sides of the top of the bottom plate.

[0011] The beneficial effects are as follows: the utility model fixes the tricycle frame to be punched through the cooperation of the positioning plate and the extrusion plate to prevent shaking during the punching process from affecting the punching effect, and starts the servo motor to drive the gear to rotate, and then drives the bottom plate to slide through the rack, so that the tricycle frame to be punched is moved, thereby continuously punching different positions, which can ensure the stability of the punching and also improve the punching efficiency.
