An automotive pipe fitting flatness detector is a device specifically designed to detect the surface flatness of automotive pipe fittings. It is mainly used to ensure that the surface of automotive pipe fittings meets the specified flatness standards during production, thereby improving the quality and safety of automotive parts.

[0003] When inspecting automotive pipe components, the pipe component is placed vertically on the machine body, and then an electric screw drives the detection ring to move up and down, so that the detection ring moves up and down along the surface of the pipe component and inspects the surface of the pipe component to obtain the surface flatness value. However, because the placement position of the pipe component may deviate from the working area of ​​the detection ring, the pipe component may fall off the center detection point of the detection ring, causing the measurement data to deviate and affecting the accuracy of the measurement.

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a device for testing the flatness of automotive pipe fittings, including a body 1, a testing ring 2 on one side of the body 1, a positioning device 3 on one side of the body 1, and a calibration device 4 on one side of the body 1. The positioning device 3 includes a cylinder 33, which is fixedly connected to the body 1. A motor 34 is fixedly connected to one side of the cylinder 33, and a winding rod 35 is fixedly connected to the output end of the motor 34. A positioning post 32 is fixedly connected to one side of the body 1. Two slides 31 are symmetrically opened on the side of the body 1 near the positioning post 32. Slide rods 36 are slidably connected to the inner walls of the two slides 31. Clamping blocks 37 are fixedly connected to one side of each slide rod 36. Ropes 311 are fixedly connected to one side of each slide rod 36. The other ends of the two ropes 311 are fixedly connected to the winding rod 35. Spring frames 39 are fixedly connected to the ends of the two slide rods 36 away from the ropes 311. The other end of 39 is fixedly connected to the machine body 1. By setting the positioning device 3, the tube is first manually placed on the positioning post 32. At this time, the motor 34 is started to drive the winding rod 35 to rotate, so that the winding rod 35 winds up the two ropes 311 by rotating, so that the two ropes 311 drive the two slide rods 36 to move in opposite directions along the inside of the two slide rails 31, so that the two slide rods 36 drive the two clamping blocks 37 to move in opposite directions. When the two clamping blocks 37 move in opposite directions to the position of the extruded tube, the tube is aligned and fixed under the push of the two clamping blocks 37, so that the position of the tube and the detection ring 2 are quickly aligned, thereby achieving rapid correction of the tube placement position. This reduces the deviation of the tube from the working area of ​​the detection ring 2 when it is placed on the machine body 1, which causes the tube to fall off the center detection point of the detection ring 2, resulting in deviation of the measurement data and affecting the measurement accuracy. This improves the placement stability and correction convenience of the tube.

[0021] Rubber pads 38 are fixedly connected to the adjacent sides of the two clamping blocks 37. The surfaces of the two rubber pads 38 are provided with multiple protrusions. By setting the rubber pads 38, the fit between the clamping blocks 37 and the surface of the pipe can be increased, and the wear caused to the surface of the pipe by the clamping blocks 37 when they squeeze the pipe can be reduced. Two limiting rods 310 are symmetrically fixedly connected to one side of the cylinder 33. The two limiting rods 310 are fixed to two spring frames 39 respectively. The springs in the spring frames 39 are sleeved on the limiting rods 310. The surfaces of the two limiting rods 310 are slidably connected to the inner walls of the two slide rods 36 respectively. By setting the limiting rods 310, the limiting rods 310 can be located inside the slide rods 36 to limit the slide rods 36, reduce the tilting of the slide rods 36 during movement, and support the springs of the spring frames 39 to reduce the large bending and deformation of the springs during the extension and retraction movement.

[0022] The alignment device 4 includes a frame 41, which is fixedly connected to the body 1. A pin 42 is slidably connected to the inner wall of the frame 41, and a circular hole block 43 is slidably connected to the inner wall of the frame 41. The size and shape of the pin 42 are adapted to the size and shape of the inner wall of the circular hole block 43. An alignment rod 44 is fixedly connected to one side of the circular hole block 43. By setting the alignment device 4, the alignment rod 44 is first manually moved, causing the alignment rod 44 to drive the circular hole block 43 to move left and right along the inside of the frame 41. When 44 moves to the designated position, the inner wall of the round hole block 43 coincides with the inner wall of any hole on the hole frame 41. At this time, the pin 42 is manually inserted into the hole frame 41 and the round hole block 43 to fix the positioning rod 44. When the personnel put the pipe on the positioning post 32, the pipe is moved to the position that is in contact with the surface of the positioning rod 44 to assist in positioning the pipe, so that the positioning rod 44 intercepts the pipe at the designated position. Then, in conjunction with the positioning device 3, the pipe is limited in multiple directions to further improve the positioning effect of the pipe.

[0023] A wear-resistant plate 45 is fixedly connected to one side of the positioning rod 44. The wear-resistant plate 45 is made of carbon ceramic. By setting the wear-resistant plate 45, the wear-resistant plate 45 can replace the positioning rod 44 in contact with the surface of the pipe, reducing the wear caused to the positioning rod 44 and improving the wear resistance and service life of the positioning rod 44. A positioning rod 46 is fixedly connected to the inner wall of the hole frame 41. The surface of the positioning rod 46 is slidably connected to the inner wall of the round hole block 43. By setting the positioning rod 46, the positioning rod 46 can be located inside the round hole block 43 to limit the positioning rod 44 and reduce the tilting of the positioning rod 44.

[0024] The working principle of this utility model is as follows: First, manually move the alignment rod 44 so that the alignment rod 44 drives the round hole block 43 to move left and right along the inside of the hole frame 41. When the alignment rod 44 moves to the designated position, the inner wall of the round hole block 43 coincides with the inner wall of any hole on the hole frame 41. At this time, manually insert the pin 42 into the hole frame 41 and the round hole block 43 to fix the alignment rod 44, thereby adjusting the position of the alignment rod 44. When the personnel put the pipe fitting on the positioning post 32, move the pipe fitting to the position that is in contact with the surface of the alignment rod 44 to assist in positioning the pipe fitting, so that the alignment rod 44 intercepts the pipe fitting at the designated position, so that the pipe fitting quickly corresponds to the position of the detection ring 2, thereby achieving the auxiliary positioning of the pipe fitting.

[0025] At this time, the start motor 34 drives the winding rod 35 to rotate, so that the winding rod 35 winds up the two ropes 311 by rotating, so that the two ropes 311 drive the two slide rods 36 to move in opposite directions along the inside of the two slide rails 31, so that the two slide rods 36 drive the two clamping blocks 37 to move in opposite directions. When the two clamping blocks 37 move in opposite directions to the position of the extruded pipe, the pipe is aligned and fixed under the push of the two clamping blocks 37, so that the position of the pipe is quickly aligned with the position of the detection ring 2, thereby achieving rapid correction of the placement position of the pipe. At this time, the drive motor drives the screw to rotate and drives the detection ring 2 to move up and down, so that the detection ring 2 moves up and down along the surface of the pipe and detects the surface of the pipe, and obtains the surface flatness value of the pipe.
