Embodiment Construction

[0018] Such as Figure 1 to Figure 2 As shown, the present invention provides a product press-fitting device suitable for hydraulic presses, including: a pressurization module 1 and a display module 2; One 14, guide block two 15 and combined disc spring 16; the display module 2 is provided with a plane pressure sensor 21 and a digital display 22.

[0019] During the press-fitting process of the product, pressure is applied to the guide block 2 15, and the guide block 15 moves downward along the outer wall of the pressure block 13, and transmits the pressure to the combined disc spring 16; the pressure after the elastic deformation of the combined disc spring 16 is buffered The block is transmitted to the pressurized product, and acts on the plane pressure sensor 21 under the product, which is displayed on the digital display 22 and controlled by the upper limit alarm to realize the press fit and protection of the product.

[0020] The limit block 12 is located directly above ...

Abstract

The invention provides a product press-fit device suitable for an oil press. The product press-fit device comprises a pressurizing module and a display module. The pressurizing module is provided witha cushion block, a limiting block, a pressing block, a first guide block, a second guide block and a combined disc spring. The display module is provided with a plane pressure sensor and a digital display. The limiting block is located right above a product, is coaxial with the cushion block and is used for positioning the pressing block. The first guide block is located on the periphery of the pressing block, a center hole is coaxial with the pressing block and the second guide block, and the first guide block is connected with the second guide block through a flange and used for lifting thepressing block. The combined disc spring is located at the upper end of the pressing block. Pressure buffered by elastic deformation of the combined disc spring is transmitted to the pressed productthrough the pressing block and acts on the plane pressure sensor below the product, the pressure is displayed through the digital display, press-fit pressure is controlled through upper limit alarm, and press-fit and protection of the product are achieved. The product press-fit device is convenient to disassemble and assemble, the pressure can be quantitatively controlled, the press-fit impact iseffectively reduced, and the product is effectively protected.

Description

technical field [0001] The invention relates to a product press-fitting device, in particular to a product press-fitting device suitable for hydraulic press-fitting and capable of quantitatively controlling the press-fitting pressure. Background technique [0002] The use of hydraulic presses for product press fitting is a commonly used technical means in the field of manufacturing. [0003] In the field of aerospace, due to the high requirements for product dimensional accuracy and fit tolerance, strict requirements are also placed on the pressure of product press-fitting, especially for small-sized products. Controlling the pressure during the press-fitting process of the product only through the pressure gauge of the hydraulic press may easily bring about the risk of excessive or inadequate press-fitting and affect product performance. Contents of the invention [0004] In view of the defects in the prior art, the object of the present invention is to provide a product...
