Description

Technical Field

[0001] This utility model relates to an automotive intake pipe inspection tool. Background Technology

[0002] The automotive intake manifold is the main air intake passage of the engine. It introduces outside air through the intake port, purifies it through the air filter, and then delivers it to the engine cylinders for combustion. The automotive intake manifold is assembled from the intake main pipe and the intake manifold. In order to ensure the installation accuracy of the automotive intake manifold, it is necessary to use special inspection tools to verify the size and shape of the assembled automotive intake manifold. Inspection tools are supporting fixtures used by industrial manufacturing enterprises to fix various workpieces so as to accurately detect the size of the workpieces.

[0003] The existing automotive intake pipe inspection tools have a limited number of positioning points, which are not distributed reasonably, making it impossible to accurately and securely position the automotive intake pipe. This causes the intake pipe to easily loosen during inspection, resulting in deviations in the inspection results. In addition, the positioning of automotive intake pipes is mostly done manually, which is cumbersome, time-consuming, and labor-intensive, leading to low inspection efficiency. Further improvements are needed. Utility Model Content

[0036] A stop block 69 is also fixed on the bottom surface of the positioning notch 651.

[0037] Working principle:

[0038] Place the intake pipe between the two end support units from top to bottom, and ensure that the tops of the first support frame 2, the second support frame 3, and the third support frame 4 in each end support unit rest on the bottom of both ends of the intake pipe. At the same time, insert the middle front end interface of the intake pipe between the two first side blocks 11 and above the top of the first support seat 10. Then, insert the left and right tail ends of the intake pipe between the two second side blocks 14 in a tail support unit on the same side and above the top of the second support seat 13.

[0039] Next, the telescopic end of the second shifting cylinder 62 in the first positioning assembly 6 is driven to retract inward or extend outward to move the first moving plate 64 to the right via the second manual slide 63, thereby causing the second positioning cylinder 66, the second pressure rod 67, and the first positioning block 65 to move synchronously; at the same time, the telescopic end of the second positioning cylinder 66 is driven to retract inward to swing the end of the second pressure rod 67 upward via the two second swing arms 68, thereby positioning the end of the second pressure rod 67 and the first positioning block 65 above and below the manifold at the left end of the intake pipe, respectively; if the lateral position is not accurate enough, the moving end of the second manual slide 63 can be manually driven to move the second positioning cylinder 66, the second pressure rod 67, and the first positioning block 65 to the left or right via the first moving plate 64; finally, the telescopic end of the second positioning cylinder 66 is driven to extend outward to swing the end of the second pressure rod 67 downward in the same way, thereby pressing and fixing the manifold in the positioning notch 651.

[0040] Simultaneously, the moving end of the third manual slide 71 is manually driven to move to the left or right to drive the second positioning block 72 to move synchronously until the positioning groove 721 is located below the manifold at the right end of the intake pipe. During this process, the telescopic end of the third positioning cylinder 73 is also driven to retract inward to drive the third pressure rod 74 to swing upward with the help of the two third swing arms 75. After the manifold is inserted into the positioning groove 721, the telescopic end of the third positioning cylinder 73 is driven to extend outward to drive the end of the third pressure rod 74 to swing downward in the same way, thereby pressing the manifold.

[0041] Next, the telescopic end of the first shifting cylinder 52 in the drive detection assembly 5 extends outward or retracts inward to drive both interface detection units to tilt backward with the help of the slide plate 51; at the same time, the telescopic end of the first positioning cylinder 54 in each interface detection unit is driven to retract inward to drive the end of each first pressure rod 55 to swing backward with the help of the two first swing arms 56 until the pressure seat 57 on each first pressure rod 55 is located behind the flange of the connecting pipe in the middle of the air inlet pipe. At this time, the rear end of the detection pin 59 in the clamping unit is located in front of the flange mounting hole. Then, the telescopic end of each first positioning cylinder 54 is driven to extend outward to press the two pressure seats 57 against the rear outer wall of the flange in the same way. Finally, the telescopic end of the first positioning cylinder 54 is driven to extend outward to drive the detection pin 59 to tilt backward until the rear end of the detection pin 59 is inserted into the flange mounting hole, thereby realizing the detection of the mounting hole position and diameter.

[0042] This invention increases the number of positioning points for the direction of the car's air intake pipe and optimizes the distribution of these points, thereby enabling accurate and stable positioning of the car's air intake pipe. This prevents the air intake pipe from loosening during testing and avoids deviations in the test results. At the same time, it also achieves automatic positioning of the car's air intake pipe, thereby simplifying the operation steps to save time and effort and improve testing efficiency.
