Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically a multi-station riveting machine. Background Technology

[0002] A riveting machine is a mechanical device that uses rivets to join items together. It is characterized by its compact structure, stable performance, and ease of operation. Riveting machines primarily rely on rotation and pressure to complete assembly. Common types include automatic riveting machines and spin riveting machines. The cold rolling riveting method using a spin riveting machine involves applying localized pressure to the rivet with a rivet rod and continuously oscillating it around a center until the rivet is formed. Based on the cold rolling trajectory of this riveting method, it can be divided into oscillating rolling riveting and radial riveting. In oscillating rolling riveting, the rivet head first makes point contact with the workpiece, and then, through a cylinder or hydraulic cylinder, applies pressure to the workpiece surface while simultaneously rolling it in all directions, causing instantaneous deformation of the workpiece surface to achieve the riveting effect. Radial riveting, on the other hand, applies pressure to a center point and then deforms and rolls the metal outwards.

[0003] Existing multi-station riveting machines can rivet workpieces, but the workpieces are located below the machine head. When placing or removing workpieces, the machine is easily bumped, and the machine may also be accidentally turned on, which may affect the safety of the operator. Therefore, the safety of the device is limited. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a motor to rotate, a screw to rotate, a moving base to move downwards, an upper connecting rod to move, a lower connecting rod to rotate around a fixed base, and a mounting frame to move. When the riveting machine body moves above the workpiece, the motor stops rotating, the second electric telescopic rod operates, the riveting machine body moves downwards to perform the operation, and after the operation is completed, the riveting machine body moves upwards, the motor rotates in the opposite direction, the mounting frame returns, and the workpiece is removed. When placing or removing the workpiece, the riveting machine body is not above the workpiece, making accidental contact less likely.

A sliding rod 201 is fixedly connected to the top of the fixed seat 2. There are four sliding rods 201, which are parallel to each other. A fixed plate 202 is fixedly connected to the top of the sliding rods 201, supporting the fixed plate 202. A motor 203 is fixedly installed on the top of the fixed plate 202. The motor 203 rotates at a relatively slow speed. The motor 203 rotates a fixed number of times. A screw 204 is fixedly mounted on the output shaft of the motor 203. Rotation of the motor 203 causes the screw 204 to rotate. A movable seat 3 is slidably mounted on the outer side of the slide rod 201. The movable seat 3 can move up and down along the slide rod 201. The main body of the movable seat 3 is a hexagonal prism. An upper connecting rod 301 is rotatably connected to the side of the movable seat 3. There are six sets of upper connecting rods 301, with two rods in each set. The two upper connecting rods 301 in the same set are parallel to each other. A mounting bracket 302 is provided above the base plate 1. The mounting bracket 302 has six sets of upper connecting rods 301 rotatably connected to the mounting bracket 302. Moving the upper connecting rods 301 moves the mounting bracket 302. Lower connecting rods 303 are rotatably connected to the side of the mounting bracket 302. There are six sets of lower connecting rods 303, with four rods in each set. The four lower connecting rods 303 in the same set are parallel to each other. The lower connecting rods 303 are rotatably connected to the fixed base 2 and rotate around the fixed base 2. A second electric telescopic rod 4 is fixedly installed on the side of the mounting bracket 302. The mounting bracket 302 and the upper connecting rods... 301 and the movable seat 3 form a parallelogram. The mounting bracket 302, the lower connecting rod 303 and the fixed seat 2 form a parallelogram. The second electric telescopic rod 4 is always perpendicular to the base plate 1. The output shaft of the second electric telescopic rod 4 is fixedly mounted on the riveting machine body 401. The riveting machine body 401 is always perpendicular to the base plate 1. When the riveting machine body 401 moves above the workpiece, it stops moving. The second electric telescopic rod 4 works, and the riveting machine body 401 moves downward to perform the operation. After the operation is completed, the riveting machine body 401 moves upward.

[0020] The first electric telescopic rod 101 is fixedly installed on the upper surface of the base plate 1. The output shaft of the first electric telescopic rod 101 is fixedly installed with a push plate 102.

[0022] The screw 204 is threadedly connected to the movable seat 3. When the screw 204 rotates, the movable seat 3 can move up and down, and the upper connecting rod 301 can move.

[0023] Among them, the four sliding rods 201 are parallel to each other, the screw 204 is parallel to the sliding rods 201, and the moving seat 3 can move up and down smoothly.

[0024] The upper connecting rod 301 and the lower connecting rod 303 do not contact each other. The upper connecting rod 301 and the lower connecting rod 303 work synchronously but will not contact each other to prevent affecting the movement of the mounting bracket 302.
