Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, and particularly relates to a riveting machine with automatic positioning. Background Technique

[0002] The riveting machine is a new type of riveting equipment developed based on the cold rolling principle, which refers to a mechanical device that can rivet items with rivets. During the processing of the automobile steering wheel, it is necessary to use the riveting machine to rivet the inner beam of the automobile steering wheel.

[0003] However, when the existing riveting machine rivets the automobile steering wheel, the automobile steering wheel is placed inside the riveting table, and the riveting mechanism is arranged above the riveting table. The riveting mechanism is used to rivet the automobile steering wheel inside the riveting table. During this process, it is necessary to position and calibrate the riveting table. The existing positioning method is as follows: the riveting table is displaced in a sliding connection manner, so that the riveting table can be moved directly above the riveting mechanism. This positioning method has positioning deviation, which will reduce the riveting quality. Therefore, the above problems need to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a riveting machine with automatic positioning, which has the effects of automatic positioning and reducing positioning deviation.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a riveting machine with automatic positioning, including a machine body, a base is fixedly connected to the bottom of the machine body, a cylinder is arranged inside the machine body, a pressing plate is fixedly connected to the output end of the cylinder, a riveting mechanism is arranged at the bottom of the pressing plate, grooves are opened on both sides inside the machine body, a motor is fixedly installed at the bottom of the groove, a first gear is fixedly connected to the output end of the motor, a second gear is rotatably connected to the inner wall of the groove, a threaded rod is fixedly connected to the center of the second gear, a sleeve is threadedly connected to the outside of the threaded rod, a connecting plate is arranged at the top of the sleeve, a riveting table is fixedly connected to the top of the connecting plate, a positioning ring is fixedly connected to the outside of the pressing plate, and a laser pen is fixedly installed inside the positioning ring.

[0006] By adopting the above technical solution, place the automobile steering wheel above the riveting table. When positioning between the riveting table and the riveting mechanism, fix the laser pointer inside the positioning ring so that the laser pointer can be on the outside of the riveting mechanism. The laser pointer emits a laser ray, and the laser ray irradiates the inner side of the machine body. Then start the motor, so that the motor drives the first gear to rotate. The first gear meshes with the second gear, and further enables the motor to drive the threaded rod to rotate. The sleeve, the connecting plate and the riveting table will move inside the groove through the rotation of the threaded rod. When the ray generated by the laser pointer irradiates the center of the riveting table, the motor stops working, and the riveting table will be directly below the riveting mechanism. Then start the cylinder, so that the cylinder drives the pressing plate and the riveting mechanism to expand and contract, and thus can rivet the automobile steering wheel on the top of the riveting table. This device locates the center point of the riveting mechanism through the laser pointer, and calibrates the position between the riveting table and the riveting mechanism through the automatic displacement of the riveting table, greatly improving the riveting quality of the automobile steering wheel.

[0007] A further setting of the present utility model is that a scale bar is provided at the edge inside the machine body, and scales are provided on the outside of the scale bar.

[0010] By adopting the above technical solution, when fixing the automobile steering wheel on the top of the riveting table, extend the center of the bottom of the automobile steering wheel to the top of the first limit pin, and extend the four corners of the bottom of the automobile steering wheel to the top of the second limit pin.

[0011] A further setting of the present utility model is that an L-shaped plate is fixedly connected to the edge of the top of the riveting table, a screw rod is threadedly connected inside the L-shaped plate, and a clamping jaw is provided at the bottom of the screw rod.

[0012] By adopting the above technical solution, rotate the screw rod so that the screw rod drives the clamping jaw to displace, and clamp the outside of the automobile steering wheel through the clamping jaw, so that the automobile steering wheel can be fixed on the top of the riveting table.

[0013] A further setting of the present utility model is that a bearing is fixedly installed on the top of the clamping jaw, and the screw rod is rotatably connected to the clamping jaw through the bearing.

[0014] By adopting the above technical solution, the screw rod and the clamping jaw rotate through the bearing, so that the clamping jaw does not rotate during the displacement of the screw rod.

[0015] A further setting of the present utility model is that a slide rail is fixedly connected to the inner wall of the L-shaped plate, and one side of the clamping jaw extends into the inside of the slide rail.

[0016] By adopting the above technical solution, one side of the clamping jaw clamps the car steering wheel, and the other side of the clamping jaw is slidably connected to the inside of the slide rail. The slide rail is a linear slide rail, ensuring that the clamping jaw will not shift during the movement process.

[0017] A further setting of the present utility model is that a heat dissipation cavity is formed inside the machine body, and a grille is fixedly connected to the inside of the heat dissipation cavity.

[0018] By adopting the above technical solution, the heat dissipation cavity is used to dissipate heat from the inside of the machine body, and the grille is used to block the heat dissipation cavity.

[0019] A further setting of the present utility model is that the number of the grilles is several, and the distances between any two of the several grilles are equal.

[0020] By adopting the above technical solution, through the arrangement of multiple grilles, it can prevent flying insects and dust from entering the inside of the machine body.

[0021] A further setting of the present utility model is that positioning blocks are fixedly connected to both sides of the outside of the base, and positioning rods are threadedly connected to the inside of the positioning blocks.

[0022] By adopting the above technical solution, one side of the positioning block is fixed to the outside of the base, and the positioning rod is threadedly connected to the positioning block and the base surface, so as to fix the base.

[0023] A further setting of the present utility model is that the number of the positioning blocks is four, and one positioning rod is threadedly connected to the inside of each positioning block.

[0024] By adopting the above technical solution, the four positioning blocks are distributed at the four corners of the base, improving the installation stability.
