A blank casting cavity pressure detection device

A detection device and pressure technology, which can be used in the application of stable tension/pressure to test the strength of materials, by measuring the acceleration and deceleration rates of fluids, and using liquid/vacuum for liquid tightness measurement. The force of the blank casting cannot be adapted to the detection device on the bottom surface of the blank casting, and the air tightness of the connection between the detection device and the casting cannot be guaranteed, so as to solve the problems of uneven extrusion and uniform connection force.

Problems solved by technology

[0004] (1) When the existing rough castings are tested, multiple strong pushing screws are required to squeeze and connect the castings. In this way, it is impossible to ensure that the extrusion force of each bolt is balanced during the extrusion connection process, so that it cannot be guaranteed The airtightness of the connection between the detection device and the casting;
[0005] (2) In the process of testing the air tightness of rough castings, the contact surface at the bottom will have certain deformation or processing defects, which will cause the bottom surface of the rough castings to be unable to match the testing device

Embodiment 1

[0042] Such as Figure 1-Figure 9 As shown, a blank casting cavity pressure detection device includes a pressure detection cover 7, a rotating sleeve 15 is provided at the center of the upper surface of the pressure detection cover 7, and an inner rotor 16 is provided in the inner cavity of the rotating sleeve 15, The upper surface groove of the inner rotor 16 is internally threaded with a screw 10, and the upper end of the screw 10 passes through the through hole at the upper end of the rotating sleeve 15 and is threaded with a turntable 11, and the outer ring wall of the pressure detection cover 7 is wound around it. The center of the circle is provided with several guide grooves 6, and guide block bars 3 are slidably connected in the guide grooves 6, and the side walls of the guide block bars 3 are provided with side guide block bars 4 perpendicular thereto, the side guide block bars 4 The lower end is provided with a base bracket 19, the lower surface of the pressure detec...

Embodiment 2

[0051] Based on the rough casting cavity pressure detection device provided in the first embodiment of the present application, the second embodiment of the present application proposes another rough casting cavity pressure detection device. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below in conjunction with the drawings and implementation methods.

[0052] Based on the first embodiment, the difference between the second embodiment and the first embodiment is that the second embodiment also has the following characteristics: refer to Figure 10 and Figure 11 As shown, the upper end of the screw 10 is threaded with a turntable 11. This knot makes the upper end of the screw 10 threaded with the turntable 11, while the lower end of the screw 10 is threaded wi...

Abstract

The invention relates to the technical field of casting detection, in particular to a blank casting cavity pressure detection device, comprising a pressure detection cover, a rotating sleeve is arranged at the center of the upper surface of the pressure detection cover, and an inner chamber of the rotating sleeve is provided with an inner cavity For the rotor, the groove on the upper surface of the inner rotor is internally threaded with a screw, and the upper end of the screw is threaded through the through hole at the upper end of the rotating sleeve to be threaded with a screw, and the outer ring wall of the pressure detection cover is opened around its center. There are several guide grooves, and guide block strips are slidably connected in the guide grooves, and the side walls of the guide block strips are provided with side guide block strips perpendicular to them. Sliding evenly on the bar, this can ensure that the connection force between the pressure detection cover and the opening end of the rough casting is more uniform, and at the same time, the rotating supporting plate can be rotated on the second inner sliding part by rotating the supporting plate accessory, so that the rotating supporting plate The parts can conveniently support the rough casting.

Description

technical field [0001] The invention relates to the field of casting detection, in particular to a blank casting cavity pressure detection device. Background technique [0002] Some castings with cavities in the foundry industry, the cavities are generally used as oil chambers, circulating water chambers, compression chambers, etc., and castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured , Injection, suction or other casting methods are injected into the pre-prepared mold, and after cooling, grinding and other subsequent processing methods, the obtained objects have a certain shape, size and performance, and the casting needs to be pressed after forming the blank. Inspect to ensure that the cavity is well sealed and there is no risk of leakage. At present, the pressure inspection of the cavity of this type of casting is performed after the finishing of the casting, and the pressure inspection of the casting is c...
