Technical Field

[0001] The utility model belongs to the technical field of connector disassembly, in particular to a device for removing rivets from a commercial vehicle frame. Background Art

[0002] The commercial vehicle frame is the skeleton of the commercial vehicle and bears the weight and load of the entire vehicle. Its structural forms mainly include side beam type, integrated type, ladder frame, etc. The production process of the frame includes design and engineering, material preparation, welding and assembly, heat treatment and surface treatment. These steps ensure that the frame has sufficient rigidity and strength to withstand the load of the car and the impact from the wheels.

[0003] Most commercial vehicle frames are riveted, which may cause wrong or crooked rivets. Usually, tools such as sledgehammers, flat shovels and punches are used to fix wrong or crooked rivets, or gas cutting is used to cut off the rivet heads and then punch out the rest. These methods have the following problems:

[0004] 1. Hammering or gas cutting increases the labor intensity of workers and reduces work efficiency;

[0005] 2. The rivet head that is hit by a sledgehammer, a flat shovel or a punch can easily injure people, so the safety factor is low;

[0006] 3. The hammer, flat shovel and punch can easily damage the surface of the workpiece, affecting the appearance quality of the product;

[0007] 4. The depth of flame cutting cannot be controlled, which often damages the frame matrix and affects product performance;

[0008] 5. Cutting operations in the workshop produce thick smoke, which seriously pollutes the working environment;

[0009] 6. Traditional rivet removal devices have long operation times and poor flexibility.

[0010] Especially on the frame assembly production line, the above problems are particularly prominent. In addition, there are also problems such as the tools for removing rivets from the frame body are bulky, difficult to locate, high risk, large space occupied, and not flexible enough to operate and carry. Utility Model Content

[0011] In order to solve the problems that tools for removing rivets are bulky, difficult to locate, dangerous, occupy a large space, and are not flexible to operate and carry, the utility model provides a commercial vehicle frame rivet removal device.

[0013] A commercial vehicle frame rivet removal device comprises a handheld frame, one end of the handheld frame is provided with a hydraulic cylinder, the axis of the hydraulic cylinder is perpendicular to the frame body; the working end of the hydraulic cylinder is provided with a rotating shaft, and a milling cutter can be detachably connected to the rotating shaft; the other end of the handheld frame is provided with a magnetic chassis that can be adsorbed on the frame body, and an electromagnetic clamp is provided in the magnetic chassis.

[0014] The mobile handheld frame is moved to one side of the rivet part, and the adsorption on the frame body is completed through the magnetic chassis, so that the milling cutter and the rivet part are corresponding, thereby improving the mobility of the device, reducing the difficulty of positioning and reducing the occupation of external operating space.

[0015] A further improvement of the utility model is that the handheld frame is in an overall arc-shaped structure, which is convenient for holding and operating.

[0016] A further improvement of the utility model is that the electromagnetic clamp comprises an internal coil which is arranged inside the magnetic chassis and generates magnetic force after being energized, and the bottom surface of the magnetic chassis is provided with an iron core which can cooperate with the internal coil.

[0017] A further improvement of the utility model is that the rotating shaft is connected to the piston rod of the hydraulic oil cylinder, and the piston rod is provided with scale lines. Observing the scale lines helps to avoid accidental damage to the frame body by the milling cutter.

[0018] A further improvement of the utility model is that the outer sleeve of the rotating shaft is provided with a spiral protective sleeve installed on the piston rod to prevent the splashing of waste chips.

[0019] A further improvement of the utility model is that the spiral protective sleeve is made of transparent rubber material, which is convenient for timely observation of the working conditions.

[0020] A further improvement of the utility model is that the rotating shaft is provided with a locking installation opening capable of accommodating a milling cutter, and the locking installation opening facilitates the replacement operation of the milling cutter.

[0021] A further improvement of the utility model is that a punch can be detachably connected to the locking installation opening, and the diameter of the punch is smaller than the diameter of the rivet. After the milling operation of the rivet is completed, the punch can be replaced to push the remaining rivet part out of the installation hole of the frame body.

[0022] A further improvement of the utility model is that a drill bit can be detachably connected to the locking mounting port, and the mounting hole on the frame body can be precision machined to improve the adaptability and matching degree of the rivet.

[0023] A further improvement of the utility model is that a pull-out remote control assembly capable of controlling the start and stop of the magnetic chassis, the hydraulic cylinder and the rotating shaft is hung on the side of the magnetic chassis.
