Press-fit fixture for special-shaped pipe workpieces

Abstract

The invention discloses a press-assembling clamp of special-shaped pipe workpieces. The press-assembling clamp comprises a fixing base, an electric controller, a press-assembling mechanism, an opening and closing mould, a workpiece sensor, a first hinge assembly, a second hinge assembly, a first holding mechanism and a second holding mechanism. A sliding groove is formed in the fixing base. According to the press-assembling clamp, the first holding mechanism and the second holding mechanism are used for driving the corresponding hinge assemblies respectively so as to enable the opening and closing mould and the workpiece sensor to move reversely in the sliding groove, and after the first holding mechanism and the second holding mechanism hold tightly in a closed mode, the press-assembling mechanism is used for assembling special-shaped pipes in a pressing mode until the special-shaped pipes are assembled on the workpieces in a pressing mode. The press-assembling process is simple, press-assembling stress is balanced, the pipes or the workpieces are effectively prevented from being damaged, and the effects of accurate press-assembling positioning, high press-assembling speed, high press-assembling efficiency are achieved. In the press-assembling process, the proper opening and closing mould is selected according to the shapes of the special-shaped pipes, so that the press-assembling clamp is suitable for pipes in different sizes and shapes, and therefore the application range of the press-assembling clamp is extended.

Description

technical field [0001] The invention relates to the technical field of pipe fitting press-fitting, in particular to a press-fitting fixture for special-shaped pipe workpieces. Background technique [0002] During the assembly process of some mechanical equipment in the prior art, there are many pipe fittings of different shapes with depth and angle requirements that need to be press-fitted to the equipment. There are two main ways to press-fit these pipe fittings. One is to press-fit the pipe directly by hand. This method is not only labor-intensive and low-efficiency, but also requires multiple people to lift for some large pipe fittings. Personal strength is not the same, it is easy to cause harm to personal safety. The other is to complete the press-fitting through numerical control equipment with complex structure. Although it can ensure the quality of product assembly, it has the defects of large equipment investment, high cost, long time for failure and maintenance, a...

Problems solved by technology

There are mainly two ways to press these pipe fittings. One is to directly press the pipe fittings manually. This method is not only labor-intensive and low in work efficiency, but also requires many people to lift some large pipe fittings. Personal strength is different, it is easy to cause harm to personal safety

The other is to complete the press-fitting through CNC equipment with a complex structure. Although the quality of product assembly can be guaranteed, there are defects such as large equipment investment and high cost, and long maintenance time in case of failure, which affects the normal operation of the production line; in addition, the CNC equipment only It can press fit pipe fittings of one specification and size. This method not only has a slow press-fit speed and low press-fit efficiency, but also has a limited scope of use
