Description

Technical Field

[0001] The utility model relates to the technical field of riveting tooling, in particular to a multi-point riveting device for a solenoid valve body and a shell. Background Art

[0002] With the rapid development of social economy, the use of solenoid valves has become one of the most common valves in people's daily life. Solenoid valves are industrial equipment controlled by electromagnetics. They are basic components for controlling fluid automation. They belong to actuators and are not limited to hydraulic and pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.:

[0003] In the patent "CN202321021726.4", a multi-point riveting device for the solenoid valve body and shell is proposed. The patent proposes that the product clamping mechanism includes a product clamping chuck arranged on the mounting plate. Since the riveting device uses a stamping machine and a special connection mold through an instantaneous high-pressure processing process, according to the cold extrusion deformation of the plate material itself, a stress-free internal inlaid dot with a certain tensile and shear strength is formed to connect the products together. Therefore, during the processing of the product, the product needs to withstand a large downward pressure. The patent clamps the chuck, which can only clamp the side wall of the product, so that the chuck needs to use a lot of force to tighten, and using strong tightening will cause indentations on the product surface, and even cause the product to deform;

[0004] For this purpose, we propose a multi-point riveting device for the solenoid valve body and shell. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a multi-point riveting device for a solenoid valve body and a shell, which overcomes the deficiencies in the prior art and aims to solve the problems in the background technology.

[0007] The lifting device includes a lifting frame, hydraulic telescopic rods are respectively installed on both sides of the lifting frame, the bottom of the hydraulic telescopic rods is fixedly installed on the upper end of the bottom plate, a baffle is slidably installed on one side of the lifting frame, electric telescopic rods for cooperating with the baffle are respectively installed on both sides inside the lifting frame, and a support table is pasted on the upper end of the baffle. In practical applications, the device is provided with a lifting device. The staff clamps and positions the product through a chuck. Subsequently, the electric telescopic rod contracts, driving the baffle to move. Then, the hydraulic telescopic rod extends, driving the lifting frame and the baffle to rise so as to support the bottom of the product, effectively protecting the product and avoiding surface damage caused by the product being stressed. After the product is processed, the hydraulic telescopic rod contracts and the electric telescopic rod extends, causing the processed product to fall to the lower part without the need for the staff to pick it up. At the same time, the device is provided with a support table. When the product is small and the bottom cannot be supported by the baffle, the support table can be used to lift it, and grooves can be opened on the surface of the support table to adapt to the irregular bottom and thus adapt to a variety of different products.

[0008] As a preferred technical solution of the present invention, a chute for cooperating with the baffle is opened on the inner wall of the lifting frame. The lifting frame is arranged in a U shape. Reinforcing ribs are fixedly arranged on the outer wall of the lower end of the baffle. The cross section of the chute on both sides of the lifting frame is convex. In practical applications, reinforcing ribs are fixed on the outer wall of the baffle to enhance the strength of the baffle and prevent the middle of the baffle from sagging after long-term use. At the same time, the cross section of the chute is convex, providing longitudinal tension for the baffle and preventing the middle of the baffle from bending.

[0009] As a preferred technical solution of the present invention, a storage box is placed on the upper end of the bottom plate. The bottom of the storage box is provided with rollers, and a buffer pad is installed inside the storage box.
