Description

Technical Field

[0001] The utility model relates to the detection field, in particular to a position detection tool for a gas-liquid separator. Background Art

[0002] There is a gas-liquid separator between the evaporator and the compressor of the automobile heat pump air conditioning system. Its function is to separate the liquid droplets in the medium, and then enter the compressor after gasification in the gas-liquid separator to prevent the liquid droplets from entering the compressor. Figure 1 The gas-liquid separator shown mainly comprises a tank body 1' and an end cover 2' arranged above the tank body 1', wherein the upper surface of the end cover 2' at least partially protrudes upward along the direction of the axis of the tank body 1' to form a first mounting portion 3', the first mounting portion 3' has an inlet 4' arranged perpendicularly to the direction of the axis of the tank body 1' and first mounting holes 5' symmetrically arranged on both sides of the inlet 4'; a second mounting portion 6' is arranged on the side wall of the tank body 1', the second mounting portion 6' is located below the first mounting portion 3' and has a second mounting hole 7' arranged parallel to the direction of the axis of the tank body 1'. The gas-liquid separator is fixed between the evaporator and the compressor through the first mounting hole 5' and the second mounting hole 7'.

[0003] Since the installation position of the gas-liquid separator is usually fixed, the distance between the two first installation holes 5', the position of the second installation hole 7' on the tank body 1', the distance between the first installation hole 5' and the second installation hole 7' in the horizontal direction and other dimensions need to be within a preset range. If the above positions and distances are not within the preset range, it will lead to difficulties in the installation process of the gas-liquid separator, unstable installation effects or even impossible installation, which increases the cost of manpower and material resources and reduces the installation efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a position measuring tool capable of detecting the position of the installation hole of the gas-liquid separator in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: the position measuring tool of the gas-liquid separator is characterized by comprising:

[0006] Testing platform;

[0007] A pressing assembly, arranged on the detection platform, for pressing the gas-liquid separator to be tested;

[0008] A first detection mechanism, disposed on the detection platform, is used to locate the two first mounting holes in the first mounting portion on the end cover of the gas-liquid separator to detect whether the distance between the two first mounting holes is within a preset range;

[0009] a second detection mechanism, provided on the detection platform, comprising a positioning structure for positioning a second mounting hole in a second mounting portion on the tank body of the gas-liquid separator, and a detection structure for detecting whether the position of the second mounting hole on the tank body and the distance in the horizontal direction from the first mounting hole are within a preset range; and

[0010] The third detection mechanism is arranged on the detection platform and is used to detect whether the deflection angle of the second mounting hole is within a preset range.

[0011] In order to enable the first detection mechanism to locate the first mounting hole, the first detection mechanism further comprises two positioning pins matching the first mounting holes. If the two positioning pins can pass through their respective first mounting holes, the distance between the two first mounting holes is within a preset range.

[0012] In order to enable the second detection mechanism to locate the second mounting hole, further, the positioning structure of the second detection mechanism includes a positioning seat, and the detection structure includes a detection member for detecting the horizontal distance between the positioning seat and the second mounting hole and a connection seat for detachably connecting the detection member to the detection platform. Since there is a certain distance between the positioning seat and the first detection mechanism, it is only necessary to measure the horizontal distance between the positioning seat and the second mounting hole to detect whether the position of the second mounting hole on the tank body and the distance from the first mounting hole in the horizontal direction are within a preset range.

[0013] The detection member can be a simple tool for measuring the length of the size, but for the convenience of measurement, preferably, the detection member is a go and no-go gauge. In this way, it is only necessary to determine whether the go gauge can smoothly extend between the positioning seat and the second mounting hole, and whether the no-go gauge cannot extend between the positioning seat and the second mounting hole.

[0014] In order to detect whether the deflection angle of the second mounting hole is within a preset range, the third detection mechanism further comprises a detection pin, and the detection end of the detection pin can be moved to extend into the second mounting hole. If the detection end can be moved to extend into the second mounting hole, the deflection angle of the second mounting hole is within the preset range.

[0015] In order to enable the detection end of the detection pin to move, the detection pin further comprises a detection part and a driving part capable of driving the detection part to move, the detection end is located at the end of the detection part, and the driving part is arranged at the end of the detection part. In this way, the driving part can drive the detection part to move forward.

[0016] The driving part can be a motor, but in order to save costs and installation space, preferably, the third detection mechanism also includes a third support seat, the third support seat has a through hole, the detection pin is inserted into the through hole, the driving part includes a spring and a push head, the spring is sleeved on the outer periphery of the detection part and is located outside the through hole, the push head is arranged at the top of the detection part, when the push head moves toward the detection end, the spring is squeezed to drive the detection part to move forward, and the spring makes the detection part always have a tendency to return to the initial position. If you want to restore the original state, just release the push head, the push head can automatically return to its position under the action of the spring restoring force, the driving part has a simple structure and is easy to operate.

[0017] The clamping assembly has a variety of structures. From the perspective of structural simplicity, preferably, the clamping assembly includes a clamping head, each clamping head is connected to its own connecting rod mechanism, and a wrench is connected to the end of the connecting rod mechanism.

[0018] Compared with the prior art, the advantages of the utility model are: the position detection tool of the gas-liquid separator detects whether the distance between the two first mounting holes is within a preset range through a first detection mechanism, detects whether the position of the second mounting hole on the tank body and the distance in the horizontal direction from the first mounting hole are within a preset range through a second detection mechanism, and detects whether the deflection angle of the second mounting hole is within a preset range through a third detection mechanism; in this way, if the position detection of the gas-liquid separator is qualified, the smooth installation process and the stability of the installation effect can be guaranteed; and if the detection of a certain mounting hole is unqualified, the distance or angle of the mounting hole can be reset in advance before installation, saving manpower and material costs and improving installation efficiency.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 2 to 4The position detection device of the gas-liquid separator of this embodiment comprises a detection platform 1 , a pressing assembly 2 , a first detection mechanism 3 , a second detection mechanism 4 , a third detection mechanism 5 and a fourth support seat 7 .

[0025] The detection platform 1 is used to place the gas-liquid separator 6 to be tested, and the pressing assembly 2, the first detection mechanism 3, the second detection mechanism 4, the third detection mechanism 5 and the fourth support seat 7 are all fixedly arranged on the detection platform 1. The upper surface of the fourth support seat 7 has a groove 71 that matches the outer periphery of the tank body 63 of the gas-liquid separator 6 to be tested, so that the gas-liquid separator 6 to be tested can be placed on the fourth support seat 7 horizontally.

[0026] The first detection mechanism 3 of this embodiment includes two positioning pins 31 matched with the first mounting holes 62a, and the positioning pins 31 are vertically arranged on the detection platform 1 through the first support seat 32. After the gas-liquid separator 6 to be tested is placed horizontally and rotated at a certain angle, the first mounting portion 62 on the end cover 61 is just located on the first support seat 32. If the two positioning pins 31 can be located in the two first mounting holes 62a in the first mounting portion 62, it means that the distance between the two first mounting holes 62a is within the preset range; otherwise, the distance between the two first mounting holes 62a is not within the preset range.

[0027] While the first detection mechanism 3 is positioning the first mounting hole 62a, the clamping assembly 2 is required to clamp the gas-liquid separator 6 to be tested to prevent the gas-liquid separator 6 to be tested from moving or rotating during positioning. The clamping assembly 2 of this embodiment has two, which are respectively located on both sides of the first support seat 32, each including a clamping head 21, a connecting rod mechanism 22 and a wrench 23. Among them, each clamping head 21 is connected to its own connecting rod mechanism 22, and the end of the connecting rod mechanism 22 is connected to the wrench 23, and the clamping head 21 is moved up or down by rotating the wrench 23 to clamp or release the gas-liquid separator 6 to be tested.

[0028] Since the gas-liquid separator 6 to be tested is placed horizontally and is cylindrical in shape, the place where it can be pressed most stably is the first mounting portion 62. In order to enable the clamping head 21 to be pressed above the first mounting portion 62, a second support seat 24 is provided below the clamping head 21 to increase the height of the clamping head 21 relative to the detection platform 1. When the clamping assembly 2 is pressing the gas-liquid separator 6 to be tested, the clamping head 21 is located just above the first mounting hole 62a and presses the first mounting portion 62.

[0029] In this embodiment, the second detection mechanism 4 includes a positioning structure and a detection structure. The positioning structure includes a positioning seat 41. The detection structure includes a detection member 42 for detecting the horizontal distance between the positioning seat 41 and the second mounting hole 64a and a connecting seat 43 that detachably connects the detection member 42 to the detection platform 1. When the detection member 42 is needed, the detection member 42 is taken out from the connecting seat 43, and the detection member 42 is put back into the connecting seat 43 after use. Among them, the positioning seat 41 includes a connecting portion 411 fixed on the detection platform 1 and a positioning portion 412 vertically arranged with the connecting portion 411; the detection member 42 is a go / no-go gauge. The above description describes that the gas-liquid separator 6 to be tested is placed horizontally and rotated at a certain angle, and the certain angle is the state in which the second mounting portion 64 (i.e., the second mounting hole 64a) on the tank body 63 is exactly parallel to the positioning portion 412. After the positioning is completed, one end of the through gauge 421 of the detection piece 42 is inserted between the positioning portion 412 and the second mounting hole 64a. If it can be inserted smoothly, then one end of the stop gauge 422 of the detection piece 42 is inserted between the positioning portion 412 and the second mounting hole 64a. If it cannot be inserted smoothly, it means that the position of the second mounting hole 64a on the tank body 63 and the horizontal distance from the first mounting hole 62a are within the preset range; otherwise, the distance between the two is not within the preset range.

[0030] like Figure 2 and Figure 4 As shown, the third detection mechanism 5 includes a detection pin 51 and a third support seat 52. The third support seat 52 has a through hole, and the detection pin 51 is inserted into the through hole. Among them, the detection pin 51 includes a detection part 511 and a driving part 512 that can drive the detection part 511 to move. The detection end is located at the end of the detection part 511, and the driving part 512 is arranged at the end of the detection part 511. The driving part 512 includes a spring 5121 and a push head 5122. The spring 5121 is sleeved on the outer periphery of the detection part 511 and is located outside the through hole. The push head 5122 is arranged at the top of the detection part 511. When the push head 5122 moves toward the detection end, the spring 5121 is squeezed to drive the detection part 511 to move forward. The spring 5121 makes the detection part 511 always have a tendency to return to the initial position. If the detection end can be moved and inserted into the second mounting hole 64a, it means that the deflection angle of the second mounting hole 64a is within the preset range; otherwise, the deflection angle of the second mounting hole 64a is not within the preset range.

[0031] The method of using the position detection fixture of the gas-liquid separator is as follows: place the gas-liquid separator 6 to be tested horizontally on the fourth support seat 7 and rotate it at a certain angle so that the second mounting portion 64 on the tank body 63 is parallel to the positioning portion 412, and the first mounting portion 62 on the end cover 61 is located on the first support seat 32. The clamping assembly 2 works to clamp the gas-liquid separator 6 to be tested, and then the first detection mechanism 3, the second detection mechanism 4 and the third detection mechanism 5 respectively detect the position of their corresponding mounting holes.
