Description
Technical Field

[0002] In the cylinder of the car engine, there are multiple water channels for cooling water circulation, which are connected to the radiator (commonly known as the water tank) placed at the front of the car through water pipes to form a large water circulation system. At the upper water outlet of the engine, there is a water pump, which is driven by a fan belt to pump out the hot water in the water channel of the engine cylinder and pump in the cold water. There is also a thermostat next to the water pump. When the car is just started and the car is cold, it is not opened, so that the cooling water does not pass through the water tank, but only circulates in the engine, commonly known as a small cycle. When the temperature of the engine reaches above 95 degrees, it is opened, and the hot water in the engine is pumped into the water tank. When the car moves forward, the cold wind blows through the water tank and takes away the heat.

DETAILED DESCRIPTION
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] The water pump is one of the core components of a car. During the processing of the water pump assembly, the processing accuracy of the water pump assembly contour is extremely high. Therefore, after the water pump assembly is processed, the contour of the water pump assembly needs to be tested with a gauge.
[0026] In the process of inspecting the impeller of the water pump assembly, since the water pump impeller is made of thin plate stamping parts, three-coordinate equipment is usually used to measure the conical surface size of the impeller. However, since the three-coordinate equipment needs to collect multiple measurement points on the impeller measurement surface, the measurement process is inefficient, cumbersome, and time-consuming.
[0027] Existing water pump impeller profile inspection tools can only inspect the profile of one type of water pump impeller, and have very poor versatility, resulting in a wide variety of water pump impeller profile inspection tools and high preparation costs for the inspection tools.
[0028] The utility model provides Figures 1 to 7 A water pump assembly impeller contour measuring tool is shown, comprising a base 1, the base 1 is L-shaped, a detection hole 7 is opened on the end face of the long plate of the base 1, a calibration base 6 is installed on the end face of the detection hole 7, a plurality of calibration columns 601 are arranged on the side of the end face of the calibration base 6 close to the detection hole 7, a mounting block 8 is arranged on the other end of the base 1, a plurality of dial indicators 9 are installed on the side of the mounting block 8 away from the detection hole 7, and the detection ends of the plurality of dial indicators 9 are in one-to-one contact with the plurality of calibration columns 601.
[0029] During use, the long plate of the base 1 is used for installing parts, and the short plate of the base 1 is used for support. The device is installed at the specified position, and the calibration base 6 is installed at the end face of the long plate of the base 1. The calibration column 601 of the calibration base 6 is located inside the detection hole 7 and contacts with the detection end of the dial indicator 9. The calibration column 601 calibrates the dial indicator 9 to avoid errors when detecting the impeller 201.
[0030] A water pump assembly 2 is installed on the end surface of the long plate of the base 1 , and the water pump assembly 2 passes through the detection hole 7 .
[0031] The water pump assembly 2 is composed of a pulley, a water pump body and an impeller 201 . The detection surface of the impeller 201 is close to one side of the detection hole 7 , and the detection end of the dial indicator 9 is in contact with one side of the impeller 201 .
[0032] The impeller of a water pump is made of thin plate stamping parts. When measuring the conical surface size of the impeller, a three-coordinate machine is usually used for detection. However, since the three-coordinate machine needs to collect multiple measurement points on the impeller measurement surface, the measurement process is inefficient, cumbersome, and time-consuming.
[0033] When in use, the water pump assembly 2 is mounted on the end surface of the long plate of the base 1 , and the water pump assembly 2 passes through the detection hole 7 for easy detection of the water pump assembly 2 .
[0034] After the above steps are completed to calibrate the dial indicator 9, the pulley rotates, and the pulley drives the impeller 201 to rotate. The impeller 201 rotates, and the dial indicator 9 detects the end face of the impeller 201. The impeller 201 rotates, and the three characteristic circles on the impeller 201 are measured respectively by three dial indicators 9. The conical surface of the impeller 201 is simulated by the three characteristic circles. During the rotation of the impeller 201, each dial indicator 9 will read a size range, and the maximum and minimum values of each dial indicator 9 that deviate from 0 are recorded, for a total of 6 values. Twice the maximum absolute value of the 6 values is taken as the contour.
[0035] A plurality of quick clips 3 are installed on the end surface of the long plate of the base 1 , and the plurality of quick clips 3 fix the water pump assembly 2 .
[0036] When in use, a plurality of quick clamps 3 clamp and fix the water pump assembly 2 so that the water pump assembly 2 is fixed on the end surface of the long plate of the base 1 .
[0037] A profiling block 4 is installed on the end surface of the long plate of the base 1. The profiling block 4 is located at the lower left of the water pump assembly 2. The side of the profiling block 4 close to the water pump assembly 2 is an arc surface.
[0038] The long plate of the base 1 is installed with a positioning sleeve 5 , and the positioning sleeve 5 is used to simulate the reference of the water pump assembly 2 .
[0039] When in use, when the water pump assembly 2 is installed, the arc surface of the profiling block 4 fits with the circular edge of the water pump assembly 2 to support the water pump assembly 2. The arc surface of the profiling block 4 fits with the circular edge of the water pump assembly 2 to position the water pump assembly 2 to avoid deviation of the water pump assembly 2 during installation.
[0040] There are two positioning sleeves 5, and the two positioning sleeves 5 position the water pump assembly 2 to prevent the water pump assembly 2 from deviating from the original position and causing errors in the detection data.
[0041] The quick clamp 3 includes a cushion block 301, which is installed on the end surface of the base 1. A clamp seat 302 is installed on the top of the end cushion block 301. Flip columns 306 are installed on both sides of the clamp seat 302. A movable column 304 is installed between the flip columns 306. A rotating shaft 305 is installed between the movable column 304 and the flip column 306. A connecting column 303 is installed on the top of the clamp seat 302. A threaded column 307 is installed on the other end of the connecting column 303. A pressing block 308 is installed on the movable end of the threaded column 307.
[0042] When in use, after the water pump assembly 2 is installed on the end surface of the long plate of the base 1 , the quick clamp 3 clamps the water pump assembly 2 to place the water pump assembly 2 on the end surface of the long plate of the base 1 .
[0043] The pad block 301 is supported, and the flip column 306 flips toward the threaded column 307, and at the same time drives the movable column 304 to flip toward the threaded column 307. At the same time, the rotating shaft 305 rotates to allow the movable column 304 to move. When the flip column 306 and the movable column 304 flip toward the threaded column 307 at the same time, the movable column 304 drives the connecting column 303 to move, and the movable end of the connecting column 303 drives the pressing block 308 to move toward the water pump assembly 2, so that the pressing block 308 presses and holds the water pump assembly 2, and fixes the water pump assembly 2. The threaded column 307 between the connecting column 303 and the pressing block 308 is used to adjust the distance between the pressing block 308 and the water pump assembly 2, and is suitable for water pump assemblies 2 of different thicknesses.
[0044] Working principle: (1) The long plate of the base 1 is used for the installation of parts, and the short plate of the base 1 is used for support. The device is installed at the specified position, and the calibration base 6 is installed at the end face of the long plate of the base 1. The calibration column 601 of the calibration base 6 is located inside the detection hole 7 and contacts with the detection end of the dial indicator 9. The calibration column 601 calibrates the dial indicator 9 to avoid errors when detecting the impeller 201.

[0046] After the above step (1) is completed to calibrate the dial indicator 9, the pulley rotates, and the pulley drives the impeller 201 to rotate. The impeller 201 rotates, and the dial indicator 9 detects the end face of the impeller 201. The impeller 201 rotates, and the three characteristic circles on the impeller 201 are measured respectively by three dial indicators 9. The conical surface of the impeller 201 is simulated by the three characteristic circles. During the rotation of the impeller 201, each dial indicator 9 will read a size range, and the maximum and minimum values of each dial indicator 9 that deviate from 0 are recorded, a total of 6 values, and twice the maximum absolute value of the 6 values is taken as the contour.
[0047] (3) The water pump assembly 2 is clamped and fixed by a plurality of quick clamps 3 so that the water pump assembly 2 is fixed on the end face of the long plate of the base 1. When the water pump assembly 2 is installed, the arc surface of the profiling block 4 fits with the circular edge of the water pump assembly 2 to support the water pump assembly 2. The arc surface of the profiling block 4 increases the supporting area to prevent the water pump assembly 2 from shaking during the rotation process. Then, the water pump assembly 2 is fixed by the quick clamps 3 to prevent the water pump assembly 2 from shaking or deflecting during the rotation measurement process.
