Problems solved by technology

The shape deviation of the head is a key point in the head inspection, especially the equipment with many holes on the head or the stirring device in the container, which has high requirements for the shape deviation of the head. If the shape deviation is too large , it may lead to the wrong height of the connecting pipe on the head or the mixing equipment cannot be accurately placed inside the equipment
Existing test samples for shape deviation of large-diameter heads are prone to deformation and difficult to use and store

Embodiment 1

[0017] Such as figure 1 As shown, a large-diameter head shape deviation inspection device includes a frame 1, a slider 2, and a scale 3. The center of the frame 1 is "0" point, and the two sides are respectively marked with the gauge distance. The scale 3 starts from the bottom to mark the gauge distance. The bottom end of the ruler 3 is preferably tapered to reduce the contact area; the slider 2 is installed on the frame 1 and is connected with the frame 1 by sliding fit; the ruler 3 is installed on the slider 2 and is movably connected with the slider 2; the ruler 3 and frame 1 form a cross.

Embodiment 2

[0019] Such as figure 2 As shown, except that a supporting point 4 is added in the middle of the frame 1 to increase the rigidity of the frame 1, the others are the same as in the embodiment 1.

[0020] The processing material of the present invention is preferably aluminum alloy, and the reasons are as follows: 1. The hardness can be guaranteed, and the deflection is relatively small when measuring large-diameter heads; Large curvature for easy handling.

[0021] Working process of the present invention is as follows:

[0022] 1. Measure the diameter of the head and mark it;

[0023] 2. Place the frame 1 on the end face of the head so that the diameter marks are just distributed on the center line of the frame 1;

[0024] 3. Adjust the frame 1 in the diameter direction, so that the readings on both sides of the contact position between the frame 1 and the head are the same (make the "0" point of the frame 1 coincide with the highest point of the head);

[0025] 4. Adjust...

Abstract

The invention discloses a checking device of a shape deviation of a large-diameter seal head. The device comprises a frame, a slide block and a ruler, wherein a 0 point is arranged in the center of the frame; scale distances are marked on the two sides of the frame and marked from the bottom end of the ruler; the slide block is mounted on the frame, and slidingly matched and connected with the frame; the ruler is mounted on the slide block, and movably matched and connected with the slide block; and the ruler and the frame are decussated. The device is simple and reasonable in structure and convenient to use, can verify the shape deviation of the large-diameter seal head, can accurately measure actual distances from various points on the internal surface of the seal head to the end face of a straight section of the seal head, provides a length adjustment basis for an adapter tube on the seal head, and ensures that equipment with a mixing device cannot be affected by the seal head.

Description

technical field [0001] The invention relates to the technical field of pressure vessels, in particular to a large-diameter sealing head shape deviation inspection device. Background technique [0002] As one of the commonly used main pressure components of pressure vessels, the head is widely used in the process of vessel production. The shape deviation of the head is a key point in the head inspection, especially the equipment with many holes on the head or the stirring device in the container, which has high requirements for the shape deviation of the head. If the shape deviation is too large , which may lead to an error in the height of the connecting pipe on the head or the inaccurate placement of the stirring equipment inside the equipment. Existing test samples for shape deviation of large-diameter heads are prone to deformation, and are difficult to use and store. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention...
