Description

Technical Field

[0001] The utility model relates to the technical field of cooler bent pipe inspection, in particular to a composite inspection tool for cooler bent pipes. Background Art

[0002] Coolers are a type of heat exchange equipment used to cool fluids. Usually water or air is used as a coolant to remove heat. There are partition type, spray type, jacket type and coil type coolers. The heat exchange pipes of the cooler are composed of several elbows. When the cooler is assembled, the elbows are installed by press fitting. The size requirements for the elbows are very high. If the size of the elbows does not meet the requirements, the assembly cannot be completed. Usually, the length of the elbows and the deformation of the pipe ends will be inspected after the bending process.

[0003] In the prior art, when inspecting bent pipes, the length and outer diameter of the pipe section are usually measured manually, and then the deformation of the pipe end is identified by the naked eye. The inspection efficiency is low and there are large errors in the inspection. There are also methods of comparison and inspection through inspection tools, but the length, outer diameter and deformation of the bent pipe need to be inspected separately through different tools. The inspection steps are cumbersome and cannot be inspected simultaneously through the same inspection tool. The inspection efficiency is low. If the inspection is carried out through a comparison inspection mold, different comparison inspection molds need to be prepared for bent pipes of different specifications, which increases the inspection cost.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments can enable technicians in this field to understand the utility model more comprehensively, but the utility model is not limited to the scope of the embodiments.

[0019] like Figure 1 and Figure 2 As shown, this specific embodiment adopts the following technical solution: it includes a base 1, an outer diameter inspection block 2, a positioning block 3, a length pass / stop inspection block 4 and a sliding assembly.

[0020] A sliding assembly is provided on the base 1, and the sliding assembly includes a slider 51 and a guide rail 52. The guide rail 52 is fixedly installed on the base 1. The slider 51 and the guide rail 52 are installed in coordination to realize the sliding of the slider 51 along the guide rail 52. The guide rail 52 and the base 1 are fixed by bolts, and a countersunk hole is provided at the bottom of the base 1. The bolts are installed from the bottom of the base 1 to connect the guide rail 52 to the base 1.

[0021] A positioning block 3 is fixedly installed on the top of the slider 51, and a raised positioning strip 6 is provided in the middle of the positioning block 3, and one end of the positioning strip 6 is an arc-shaped structure. An outer diameter inspection block 2 is provided at the end of the positioning block 3 away from the arc-shaped structure of the positioning strip 6, and the end of the positioning block 3 away from the outer diameter inspection block 2 is also an arc-shaped structure. Two through holes are provided on the outer diameter inspection block 2 for the cooler elbow 10 to pass through, and a limit block 7 is provided at the other end of the positioning block 3. The outer diameter inspection block 2 is installed on the top of the slider 51 by bolts. During inspection, the cooler elbow 10 is placed on the top of the positioning block 3 and is arranged around the outer periphery of the positioning strip 6 to inspect whether the shape of the elbow 10 is deformed. The end of the elbow 10 passes through the through hole of the outer diameter inspection block 2 to inspect the outer diameter size of the elbow 10.

[0022] The slider 51 can translate along the guide rail 52, driving the positioning block 3 and the outer diameter inspection block 2 to move synchronously, thereby driving the bent pipe 10 to move synchronously. The limit block 7 is installed on the top of the positioning block 3 by bolts, and different screw holes can be set on the top of the positioning block 3 to be applied to the inspection of bent pipes of different specifications. The position of the cooler bent pipe 10 is limited by the limit block 7 and the positioning strip 6 to prevent the bent pipe 10 from sliding.

The side of the length check block 4 close to the slider 51 is a step surface 41. The slider 51 translates to drive the elbow 10 to translate, and the end face of the elbow 10 translates along the step surface 41 of the length check block 4. If the elbow 10 is stuck at the corner of the step surface 41, it indicates that the length of the elbow 10 meets the requirements and the length of the elbow 10 can be inspected.

[0024] Working principle: The bend 10 of the cooler is placed on the positioning block 3 for inspection, the positioning bar 6 inspects whether the bend 10 of the cooler is deformed on the outside, the outer diameter inspection block 2 inspects the outer diameter of the bend 10, and the slider 51 slides along the guide rail 52 to drive the bend 10 to slide along the step surface 41 of the length pass / stop inspection block 4, and the bend 10 translates from the concave part to the convex part of the step surface 41. If the bend 10 is stuck at the corner of the step surface 41, it indicates that the length of the bend 10 meets the requirements, and the length of the bend 10 can be inspected, and the length, outer diameter and deformation of the pipe section of the bend 10 can be inspected at the same time, and the inspection efficiency is high; the positions of the length pass / stop inspection block 4 and the limit block 7 can be changed, and the outer diameter inspection block 4 with perforations of different apertures can be replaced, and the bends 10 of different lengths and outer diameters can be inspected, and the inspection cost is reduced.
