Press-mounting, locking and balancing device for blanking cap and press-mounting machine for blanking cap

Abstract

The invention provides a press-mounting, locking and balancing device for a blanking cap and a press-mounting machine for the blanking cap. The press-mounting, locking and balancing device for the blanking cap comprises a baseplate, a stop block mounted below the baseplate, a pair of clamping frames mounted above the baseplate and being in sliding fit with the baseplate, an X-direction driving mechanism used for driving the pair of clamping frames, tubular fixed columns mounted above the clamping frames, limit pins in sliding fit with the fixed columns in a Z direction, Z-direction driving mechanisms mounted on the fixed columns and used for driving the limit pins, and stop collars mounted on the baseplate, wherein each clamping frame is provided with spaced clamping arms; through holes communicated with the inner chambers of the fixed columns are formed in the clamping frames; and when the X-direction driving mechanism drives the pair of clamping frames to slide in opposite directions to reach the working position, the inner chambers of the stop collars are communicated with the inner chambers of the fixed columns and the through holes. According to the invention, the mechanism design is simplified and the universality is enhanced.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a locking balance device used for a cap pressing machine and a cap pressing machine using the device. Background technique [0002] Process holes such as water holes, oil holes, and sand cleaning holes are provided on the engine cylinder block and cylinder head. These process holes need to be glued and pressed to seal the plugging caps. At present, the plug is generally pressed by a plug press machine, such as the machine tool disclosed in the Chinese utility model patent with the application number 201120417586.3 and the name "engine cylinder bowl plug servo gluing press-fitting machine tool". During the pressing process of the plugging machine, the pressure head of the plugging cap is generally driven by hydraulic pressure, and the pressing force is relatively large. Therefore, it is necessary to set a support cylinder on the opposite side of the pressing part to balance the pressing fo...

Problems solved by technology

However, the prerequisite for the balance of the press-fitting force when both sides are press-fitted at the same time is that the process holes on both sides of the cylinder block are arranged symmetrically and coaxially. The axes coincide, which is difficult to achieve in actual production, and the press-fitting process cannot be absolutely synchronized

Under the condition that the number of process holes on both sides of the cylinder block is asymmetrical, in order to achieve the balance of the press-fitting force, the invention fixes the ejector rod on the cantilever on the side with a small number (equivalent to setting up the support cylinder), which still cannot be completely solved. The equipment complexity problem of press-fitting force balance
