Description

Technical Field

[0001] The utility model relates to the technical field of radiator air tightness detection tooling, in particular to a radiator dry inspection bulkhead component and a dry type detection tooling. Background Art

[0002] The automobile radiator is the main component for cooling the engine. It can reduce the temperature of the engine coolant, keep the engine in normal working condition, and protect the engine from damage caused by overheating. Usually, the radiator needs to be leak tested to ensure that the sealing of the radiator is qualified. The air tightness detection methods of the radiator include bubble detection, water detection and dry detection (pressure difference) detection. Among them, the dry detection has its unique advantages over the bubble detection and water detection, and is widely used. However, due to the dimensional tolerance and deformation of the parts of the radiator core itself, during the dry inspection, the sealing plug of the dry detection tooling will have a false alarm of radiator core leakage due to poor sealing, resulting in unnecessary waste of work time and product scrapping.

[0003] Therefore, it is urgent to propose a radiator dry inspection bulkhead assembly and a dry inspection tooling to solve the above problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The radiator dry inspection bulkhead assembly provided in this embodiment can improve the leakage detection pass rate and avoid unnecessary waste of work time and product scrapping.

[0034] Specific as Figure 1As shown, the radiator dry inspection bulkhead assembly includes a mounting plate 100, a bulkhead body 200 and a floating joint 300. The mounting plate 100 is used to install the radiator dry inspection bulkhead assembly, and the bulkhead body 200 is used to block the radiator pipe opening. The floating joint 300 includes a fixed end and a floating end, and the floating end can float in a plane perpendicular to the axial direction of the floating joint 300. The fixed end is connected to the mounting plate 100, and the floating end is connected to the bulkhead body 200. By setting the floating joint 300 to connect the mounting plate 100 and the bulkhead body 200, the mounting plate 100 and the bulkhead body 200 are flexibly connected. That is, when the size of the radiator pipe opening is slightly deformed, the floating end of the floating joint 300 can float to drive the bulkhead body 200 to float in a plane perpendicular to the axial direction of the floating joint 300 (the cross section where the radiator pipe opening is located) to adjust the angle of the bulkhead body 200 at will, so that the bulkhead body 200 can be smoothly aligned with the radiator pipe opening, improve the qualified rate of leakage detection, and avoid unnecessary waste of work time and product scrapping.

[0035] It should be noted that the fixed end of the floating joint 300 is provided with an internal thread, and the floating end of the floating joint 300 is provided with an external thread.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, in order to facilitate the connection between the floating joint 300 and the bulkhead body 200, the radiator dry bulkhead assembly also includes a fixing seat 400, which is located between the floating end and the bulkhead body 200 and is connected to the floating end and the bulkhead body 200 respectively.

[0037] Furthermore, in order to limit the floating range of the floating end of the bulkhead body 200 or the floating joint 300 or the fixed seat 400, the radiator dry inspection bulkhead assembly also includes a limiter 500, one end of the limiter 500 is fixedly connected to the mounting plate 100, and the other end is loosely connected to the fixed seat 400 to limit the range of movement of the fixed seat 400 in a direction perpendicular to the axis of the floating joint 300.

[0038] Optionally, the limiting member 500 is a limiting rod, and a matching hole is provided on the side of the fixed seat 400 close to the floating joint 300. One end of the limiting rod is fixedly connected to the mounting plate 100, and the other end of the limiting rod is inserted into the matching hole. The radial dimension of the limiting rod is smaller than the radial dimension of the matching hole. When the floating range of the fixed seat 400 is too large, the inner wall of the matching hole abuts against the outer wall of the limiting rod to limit the floating range of the fixed seat 400.

[0039] Furthermore, in order to limit the consistency of the floating range of the fixing seat 400 in all directions, a plurality of limit rods are provided, and the plurality of limit rods are evenly distributed around the floating joint 300 circumferentially, and the fixing seat 400 is provided with a plurality of matching holes corresponding to the limit rods.

[0040] In this embodiment, the number of the limiting rods is two.

[0041] In order to return the floating end of the floating joint 300 to its original position, the radiator dry bulkhead assembly further comprises an elastic member 600 , and two ends of the elastic member 600 are respectively abutted against the mounting plate 100 and the fixing seat 400 .

[0042] In this embodiment, the elastic member 600 is a spring, and the spring is sleeved on the floating joint 300, which is simple to configure and low in cost.

[0043] In order to increase the stability of the spring end, a first annular groove 401 is provided on one side of the fixing seat 400 close to the floating joint 300 , and the spring is clamped in the first annular groove 401 to prevent the spring from deviating.

[0044] Continue as Figure 1 and Figure 3 As shown, in order to increase the strength of the mounting plate 100, the radiator dry inspection bulkhead assembly further includes a first clamping plate 700 and a second clamping plate 800, the first clamping plate 700 is located on the side of the mounting plate 100 away from the floating joint 300, the second clamping plate 800 is located on the side of the mounting plate 100 close to the floating joint 300, and the first clamping plate 700 and the second clamping plate 800 are clamped and connected to the mounting plate 100. Optionally, a plurality of mounting holes are provided around the first clamping plate 700, the second clamping plate 800 and the mounting plate 100, and bolts are passed through to connect the first clamping plate 700, the second clamping plate 800 and the mounting plate 100.

[0045] It should be noted that the first clamping plate 700 and the second clamping plate 800 are provided to increase the connection strength between the mounting plate 100 and the fixed end of the floating joint 300. The fixed end of the floating joint 300 is provided with an internal thread, and a screw can be sequentially passed through the first clamping plate 700, the mounting plate 100, the second clamping plate 800 and threadedly connected with the fixed end of the floating joint 300.

[0046] In this embodiment, the spring abuts against the second clamping plate 800. The same principle as the spring is clamped on the mounting plate 100, the second clamping plate 800 is provided with a second annular groove near the spring, and the spring is clamped in the second annular groove.

[0047] The dry inspection tooling provided in this embodiment includes the above-mentioned radiator dry inspection bulkhead assembly. When the size of the radiator pipe mouth is slightly deformed, the angle of the bulkhead body 200 in the radiator dry inspection bulkhead assembly can be adjusted at will, so that the bulkhead body 200 can be smoothly aligned with the radiator pipe mouth, thereby improving the leakage detection pass rate and avoiding unnecessary waste of work time and product scrapping.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
