[0002] As a key component of the braking system, the brake hose is related to the safety performance of the entire vehicle. It is mainly responsible for transmitting the pressure of the brake pedal to the brake so that the vehicle can stop in time. The brake hose is generally made of rubber or metal and needs to have corrosion resistance, high temperature resistance, pressure resistance and other characteristics to ensure the normal operation of the braking system.

[0003] The docking accuracy of the brake oil pipe connector directly affects the performance of the brake oil pipe. Most of the brake oil pipe connectors are divided into sub-connectors and female connectors. When the brake oil pipe is connected, the sub-connector is screwed into the female connector through threads to ensure that the connection of the brake oil pipe is accurate and stable. The concentricity of the sub-connector and the female connector directly affects whether the connection of the brake oil pipe connector is tight and whether there is a gap at the connector.

When it is necessary to test the concentricity of the brake oil pipe connector, the female connector 7 is placed into the female connecting groove 12, and the sub-connector 6 is placed into the sub-connecting groove 11. Then the left detection sleeve 1 and the right detection sleeve 2 are closed to clamp the brake oil pipe connector therebetween. Then the left detection sleeve 1 and the right detection sleeve 2 are fixed together by the clamping structure 5. The two semicircular ring sleeves 3 clamp the sub-connector 6 so that the semicircular ring sleeves 3 are concentric with the sub-connector 6. Then the detection structure 4 detects the center of the semicircular ring sleeves 3 and the center of the sub-connector 6. Then the center of the sub-connector 6 is compared with the center of the female connector 7 to calculate the concentricity of the sub-connector 6 and the female connector 7.

[0035] Reference Figure 2 and Figure 3A circular limiting groove 13 is provided on the circumferential surface of the sub-connecting groove 11, and a spring 312 is fixed in the limiting groove 13. One end of the spring 312 facing away from the limiting groove 13 is fixedly connected to the semi-circular ring jacket 3. The semi-circular ring jacket 3 is partially located in the limiting groove 13. A plurality of springs 312 are arranged in a circular array with the center of the semi-circular ring jacket 3. The limiting groove 13 limits the movement of the semi-circular ring jacket 3 in the axial direction, thereby making the detection of the concentricity of the oil pipe joint more accurate. The semicircular ring jacket 3 includes a left semicircular ring jacket 31 and a right semicircular ring jacket 32. The left semicircular ring jacket 31 is fixedly connected with an arc-shaped reinforcement rod 311 at one end away from the hinge, and the right semicircular ring jacket 32 ​​is provided with an arc-shaped reinforcement groove 321 at one end away from the hinge. When the left semicircular ring jacket 31 and the right semicircular ring jacket 32 ​​are merged, the reinforcement rod 311 is inserted into the reinforcement groove 321, thereby limiting the relative displacement of the left semicircular ring jacket 31 and the right semicircular ring jacket 32 ​​when they are merged, thereby making the detection of the concentricity of the oil pipe joint more accurate.

[0036] Reference Figure 1 and Figure 2 The detection structure 4 includes a touch pressure rod 41, a touch pressure sensor 42 and a wireless signal transmitter 43. A plurality of touch pressure rods 41 are provided, and the plurality of touch pressure rods 41 are evenly distributed on the surfaces of the left semicircular ring jacket 31 and the right semicircular ring jacket 32. The touch pressure rod 41 is parallel to the axis of the left semicircular ring jacket 31. One end of the touch pressure rod 41 away from the left semicircular ring jacket 31 and the right semicircular ring jacket 32 ​​is pointed. The touch pressure sensor 42 is fixedly arranged on one side of the sub-connecting groove 11. The touch pressure sensor 42 is a semicircular ring sensor, and the inner circle radius of the touch pressure sensor 42 is larger than the inner circle radius of the semicircular ring jacket 3. The pointed end of the touch pressure rod 41 contacts the touch pressure sensor 42, and the wireless signal transmitter 43 is connected to the touch pressure sensor 42. When the concentricity of the brake oil pipe is tested, the touch pressure sensor 42 senses the positions of multiple touch pressure rods 41 on the surface of the touch pressure sensor 42, and then the touch pressure sensor 42 transmits the signal to the wireless signal transmitter 43, and the wireless signal transmitter 43 transmits the signal to the operator. The operator calculates the center of the semicircular ring sleeve 3 and the center of the sub-connector 6 according to the positions of the multiple touch pressure rods 41 on the surface of the touch pressure sensor 42. Since the positions of the female connector 7 and the left detection sleeve 1 and the right detection sleeve 2 are fixed, the position of the center of the female connector 7 is fixed. Then the operator obtains the concentricity of the brake oil pipe connector by calculation.

[0037] Reference Figure 1 and Figure 4The clamping structure 5 includes a left clamping block 51 and a right clamping block 52. The left clamping block 51 is fixedly arranged on the side of the left detection sleeve 1 away from the hinge, and the right clamping block 52 is arranged on the side of the right detection sleeve 2 away from the hinge. A clamping rod 511 is fixedly connected to the side of the left clamping block 51 close to the right clamping sleeve, and a right-angled triangle block 512 is fixedly connected to the end of the clamping rod 511 away from the left clamping block 51. The clamping rod 511 is connected to a right angle side of the right-angled triangle block 512. A locking groove 521 is provided at one end of the right locking block 52 close to the left locking block 51, and a pin spring groove 522 perpendicular to the locking groove 521 is provided in the locking groove 521, and a spring pin 523 is slidably connected in the pin spring groove 522, one end of the spring pin 523 is located in the locking groove 521, and the other end is fixedly connected to a locking spring 524, and the locking spring 524 is fixedly connected to the bottom of the groove of the pin spring at one end facing away from the pin spring, and an unlocking rod 525 is fixedly connected to the end where the spring pin 523 is connected to the locking spring 524, and the other end of the unlocking rod 525 passes through the right locking block 52 to reach the outside of the right locking block 52, and the unlocking rod 525 is slidably connected to the right locking block 52, and a handle 526 is fixedly connected to one end of the unlocking rod 525 located on the outside of the right locking block 52. When the left detection sleeve 1 and the right detection sleeve 2 need to be connected by clamping, the clamping rod 511 and the right-angled triangle block 512 are extended into the clamping groove 521, and the hypotenuse of the right-angled triangle block 512 contacts the spring pin 523 and moves the spring pin 523 in the direction of compressing the clamping spring 524 until the left detection sleeve 1 and the right detection sleeve 2 are completely closed, and the clamping spring 524 rebounds, so that the spring pin 523 abuts against the surface of the clamping rod 511, thereby clamping the clamping rod 511 and the right-angled triangle block 512 in the clamping groove 521, so that the left detection sleeve 1 and the right detection sleeve 2 are closed and fixed. After the inspection of the brake oil pipe is completed, the handle 526 is pulled to pull the unlocking rod 525 outward, thereby driving the spring pin 523 to completely retract into the pin spring groove 522, thereby releasing the fixation of the clamping rod 511 and the right-angled triangle block 512, so that the left detection sleeve 1 and the right detection sleeve 2 can be opened smoothly.

[0038] The specific implementation principle of the present application is as follows: when it is necessary to perform a concentricity test on the brake oil pipe connector, the female connector 7 of the brake oil pipe connector is placed into the female connector groove 12, and the sub-connector 6 is placed into the sub-connection groove 11, and then the left detection sleeve 1 and the right detection sleeve 2 are closed, so that the clamping rod 511 and the right-angled triangle block 512 are extended into the clamping groove 521, and the hypotenuse of the right-angled triangle block 512 contacts the spring pin 523 and moves the spring pin 523 in the direction of the compressed clamping spring 524 until the left detection sleeve 1 and the right detection sleeve 2 are completely closed, and the clamping spring 524 rebounds, so that the spring pin 523 abuts against the surface of the clamping rod 511, thereby clamping the clamping rod 511 and the right-angled triangle block 512 in the clamping groove 521, thereby closing and fixing the left detection sleeve 1 and the right detection sleeve 2. At this time, the left semicircular ring sleeve 31 and the right semicircular ring sleeve 32 clamp the sub-connector 6, and then the touch pressure sensor 42 senses the positions of the multiple touch pressure rods 41 on the surface of the touch pressure sensor 42, and then the touch pressure sensor 42 transmits the signal to the wireless signal transmitter 43, and the wireless signal transmitter 43 transmits the signal to the operator. The operator calculates the center of the sub-connector 6 according to the positions of the multiple touch pressure rods 41 on the surface of the touch pressure sensor 42, and then compares the center of the sub-connector 6 with the center of the female connector 7 to calculate the concentricity of the brake oil pipe joint.
