Description

Technical Field

[0001] This utility model belongs to the field of measurement technology of product length, thickness or similar linear dimensions characterized by mechanical methods under IPC classification G01B5 / 00. In particular, it relates to an improved auxiliary tooling structure for rapid standard detection of spatial positional relationships such as length, outer diameter, and bending angle of engine oil pipe assembly. It is suitable for standard shape simulation and limiting fixation of engine oil pipe assembly products, while quickly completing integrated comparison and measurement. Background Technology

[0002] Engine oil pipes need to deliver fuel or lubricating oil to various components. Their routing dimensions, bracket installation positions, and pipe end face contours must strictly match the design requirements to avoid vibration and friction perforation or cracking.

[0003] Engines require numerous oil lines to deliver and recover fuel and lubricating oil to various engine components. These oil lines must not interfere with or be too close to any engine components. If they do, the continuous vibrations of the engine during operation can cause friction and collisions between the lines and nearby parts, leading to perforation or rupture. Therefore, the dimensions and routing of the oil lines are subject to strict requirements. Furthermore, since pipe clamps and supports are used for connection during installation, some assembly and correction are unavoidable during manufacturing. During assembly and correction, the various connection points and areas prone to interference become crucial. To ensure correct installation and use of the oil lines after correction, a tooling system capable of quickly and effectively detecting and identifying whether the oil line's dimensions and routing meet the requirements is needed.

[0004] Patent application 202221198171.6 discloses a detection device for an engine turbocharger return oil pipe, comprising: a base; at least one movable detection block disposed on the base, having a detection groove thereon for receiving at least a portion of the return oil pipe; at least one fixed detection block disposed on the base, having a detection groove thereon for receiving at least a portion of the remaining portion of the return oil pipe; wherein each detection groove has at least one corner portion that matches a pipe segment on the return oil pipe that engages with the detection groove; the angle β formed by the opening direction of the detection groove of at least one movable detection block and the opening direction of the detection groove of at least one fixed detection block is greater than 0°; the movable detection block can switch between a detection position and a loading position.

[0005] Existing testing fixtures suffer from drawbacks such as limited functionality, low efficiency, and heavy reliance on manual labor. Specifically, a particular fixture may only be compatible with oil pipes with a specific bending radius. If the oil pipe's routing is adjusted, such as by adding a new bending angle, custom-made fixtures are required, leading to high production costs and long lead times. This demonstrates poor compatibility with oil pipes from different engine models with significant differences in routing and support structure. Consequently, these fixtures cannot meet the demands for multi-dimensional, rapid, and accurate testing. Utility Model Content

[0034] The rapid testing fixture for automotive oil pipe assembly has significant shortcomings in terms of functional coverage, testing efficiency, and ease of operation. Specifically:

[0035] 1) Functional Dimension: Simplicity and Limitations; Existing tooling often focuses on a single inspection, such as oil pipe length, end face sealing, and bracket hole matching, lacking integrated inspection of multiple parameters such as oil pipe bending / twisting, bracket installation position, and pipe end face contour. For example, some tooling can only inspect oil pipe length, lacking the ability to inspect key indicators such as the interference risk between the oil pipe and engine components and the bracket installation accuracy, resulting in potential problems such as large deviations in oil pipe alignment and misaligned bracket installation even after oil pipe correction.

[0036] 2) Testing efficiency: Inefficient and reliant on manual labor; cumbersome testing process: requires manual operation of "oil pipe fixing → single item testing → data recording → adjustment and calibration" in sequence, with many steps and long time consumption, which is difficult to match the needs of "mass production and rapid calibration" of engine oil pipes.

[0037] 3) High reliance on manual labor; the test results depend on the operator's experience and judgment, such as visually inspecting whether the oil pipe routing is compliant. There is a lack of automated testing and automatic data recording functions, which can easily lead to a decrease in testing accuracy due to human error.

[0038] 4) Adaptability; lack of versatility and flexibility.

[0039] This utility model includes the following core structure and functions:

[0040] 1) Basic installation and coordinate reference module;

[0041] Base plate: Serves as the mounting base for the tooling table. Equidistant lines are machined to check the positional accuracy of each base.

[0042] Reference mount: Mounted on the base plate, the coordinate system of the test is determined by three-coordinate calibration, providing a reference for subsequent testing.

[0043] 2) Pipeline routing and support installation detection module;

[0044] Slider assembly: The slider base is fixed to the base plate by bolts, and the limit pin and slider are installed on the slider base. The slider can slide freely in the groove of the slider base, and the limit pin limits the sliding range.

[0045] Limit block: It is designed with a positioning pin hole, which corresponds to the position of the oil pipe mounting hole. After the positioning pin is installed into the positioning pin hole, the limit block is installed on the slider by bolts and moves with the slider to detect the oil pipe routing dimensions.

[0046] Limiting base: Fixed to the base plate, the size / shape of the limiting base cavity groove is designed according to the oil pipe routing and is used to detect the oil pipe shape and size;

[0047] Support base: Installed on the base plate, the support hole detection hole position and cavity groove size / shape are designed according to the oil pipe routing, used to detect the oil pipe routing; the limit block is installed on the support base, used to detect the oil pipe end face contour size.

[0048] 3) Oil pipe fixing and end face detection module;

[0049] Tightening block assembly: The tightening block base is installed on the base plate, and the tightening block is fixed to the tightening base by tightening bolts. The tightening bolts control the tightening / loosening of the tightening block body and the oil pipe end face, so as to realize the rapid fixation and inspection of the oil pipe end face;

[0050] Clamping assembly: The clamping base is mounted on the base plate, and the clamping device is mounted on the clamping base for clamping detection of the tubing support.

[0051] 4) Operation and Identification Module;

[0052] Handles: facilitate the handling and operation of the tooling table;

[0053] Nameplate: Marks the technical parameters and instructions for use of the tooling table.

[0054] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] Example 1: As shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, the base plate 1 is a long strip-shaped square plate extending from left to right.

[0056] A slider base 5 is fixed to the middle of the upper left side of the base plate 1 with bolts. The top of the slider base 5 is provided with a longitudinal through groove, through which the slider body 4 passes longitudinally. The left end of the slider body 4 extends out of the left port of the longitudinal through groove, and the right end of the slider body 4 passes through and extends out of the right port of the longitudinal through groove before a first limiting block 10 is fixed at the right end. A tightening block base 7 is fixed to the rear left side of the base plate 1, behind the slider base 5. A tightening block body 8 is hinged to the rear side of the tightening block base 7. A through hole is opened in the middle of the longitudinal direction of the first limiting block 10, and a hole is opened in front of the through hole. The hole is pressed and tightened through the positioning pin 11 to the edge of the front annular hole of the screw block 8; the first limiting base 12 and the second limiting base 13 are longitudinally fixed in sequence at intervals on the rear side of the screw block base 7, that is, the upper middle side of the base plate 1; the bracket base 16 is fixed at the middle of the right end of the upper side of the base plate 1; the clamping device 15 is vertically fixed on the upper left side of the bracket base 16 through the clamping base 14; the second limiting block 17 is installed on the rear side of the right end wall of the bracket base 16; the top surfaces of the first limiting base 12, the second limiting base 13 and the second limiting block 17 have longitudinally opened cavity grooves.

[0057] As mentioned above, the upper surface of the base plate 1 is machined with equidistant lines 18 that are crisscrossed to detect whether the positions of each base, such as the slider base, the limiting base, the clamping base, and the bracket base, are accurate.

[0058] As mentioned above, a mounting base 2 is set at the upper corner of the base plate 1, and a three-coordinate disk 20 is set next to the base 2; the three-coordinate calibration position of the three-coordinate disk 20 is used to determine the detection coordinate system of the oil pipe inspection tool.

[0059] As described above, a first limiting block 10 is fixedly connected to the right end of the slider body 4 by bolts, and the first limiting block 10 moves together with the slider body 4. At least two longitudinally arranged positioning holes 41 are vertically opened in the upper middle part of the left section of the slider body 4, and correspondingly, limiting pins 3 are installed in holes opened on the top wall of the longitudinal through groove at the top of the slider base 5. The limiting pins 3 pass through the positioning holes 41 to fix the relative position of the slider body 4 and the slider base 5, so as to accommodate the standard length of oil pipes of different specifications. The slider body 4 can slide freely in the top through groove of the slider base 5, and is limited by the limiting pins 3.

[0060] In the aforementioned configuration, the front of the tightening block base 7 protrudes upwards and backwards, and a clamp 71 protrudes backwards in a fork shape. A pin 72 is vertically inserted and installed between the forks at the rear end of the clamp 71. The rear end of the tightening block body 8 is connected to the rear wall of the tightening block base 7 via a tightening bolt 9. The middle section of the tightening block body 8, which is horizontally placed and extends laterally, has a groove 81 through which the pin 72 passes and slides. A fork-shaped opening 82 is provided at the front end of the tightening block body 8. The left side of the fork-shaped opening 82 presses against the right end face of the first limiting block 10. The oil pipe passes through the central hole of the fork-shaped opening 82 and the central hole of the first limiting block 10. The tightening bolt 9 is used to control the tightening and loosening of the tightening block body 8 and the end face of the oil pipe.

[0061] As described above, clamp 15 is used to clamp the tubing support. Clamp 15 includes a rear seat plate 151, a front clamp 152, an upper pin 153, a lower pin 154, a wrench 155, a sliding sleeve 156, a pressure rod 157, and an eccentric worm gear 158. A front clamp 152 is vertically fixed at the center of the front side of the seat plate 151. The front clamp 152 has a vertical slot in the center, where the upper and lower parts are horizontally inserted with an upper pin 153 and a lower pin 154, respectively. A sliding sleeve 156 is vertically fixed at the lower end of the vertical slot. The upper section of the pressure rod 157 is fitted with a bushing spring in the sliding sleeve 156. The upper end of the pressure rod 157 is hinged to an eccentric worm gear 158. The lower end of the wrench 155 is hinged to the lower pin 154. The lower arc edge of the wrench 155 presses down and connects to the top surface of the eccentric worm gear 158. When the upper section of the wrench 155 is moved forward and backward, the lower section of the wrench 155 rotates with the lower pin 154 as the fulcrum. The bottom end of the wrench 155 pushes against the eccentric worm gear 158, causing the pressure rod 157 to move up and down, pressing down or lifting up to disengage from the oil pipe support. When the wrench 155 is pulled upwards, the lower arc edge of the wrench 155 rotates, releasing the tight contact with the top surface of the eccentric worm gear 158. The pressure rod 157 is pulled up to the top, and the upper rear wall of the wrench 155 presses against the front side of the upper pin 153. At this time, the upper pin 153 acts as a limit stop. When the wrench 155 is rotated forward and downwards to press down, the lower arc edge of the wrench 155 rotates, making tight contact with and squeezing the top surface of the eccentric worm gear 158. The pressure rod 157 is pressed down to the bottom, and the lower oil pipe bracket clamps the oil pipe.

[0062] As mentioned above, a handle 6 is installed on the upper edge of the base plate 1. This facilitates handling, moving, installation, and maintenance.

[0063] As mentioned above, a nameplate 19 is installed on the front edge of the middle part of the upper surface of the base plate 1.

[0064] In this embodiment of the invention, the dimensions and shapes of the longitudinal cavity grooves on the top surfaces of the first limiting base 12, the second limiting base 13, and the second limiting block 17 are designed according to the routing of the oil pipe to ensure the correct dimensions of the oil pipe. The second limiting block 17 is used to ensure the correct contour dimensions of the oil pipe end face.

[0065] In this embodiment of the utility model, the reference base 2 is a positioning support component of the tooling, used to provide a precise installation reference for the oil pipe during the assembly and testing process, ensuring the positional accuracy of the oil pipe; the three-coordinate disk 20 installed next to the reference base 2 has reference markings with X, Y, and Z marks engraved on its surface. By using the letters X, Y, and Z to correspond to the three-dimensional spatial coordinate axes, the reference direction and positioning logic of the tooling are clearly defined, assisting the operator in understanding the reference system of the tooling.

[0066] The implementation principle of this embodiment is as follows:

[0067] 1) First, operate handle 6 to place base plate 1 securely;

[0068] 2) Based on the shape and specification parameters of the oil pipe to be tested, adjust the reference base 2 according to the coordinate measuring machine 20; and extend and retract the slider 4, and lock it with the limit pin 3 and the positioning pin 11.

[0069] 3) Check the tightening block 8 and clamp 15, and keep the top surface cavity grooves of the first limiting base 12, the second limiting base 13 and the second limiting block 17 clean and usable;

[0070] 4) Embed the middle section of the oil pipe into the cavity groove on the top surface of the first limiting base 12, the second limiting base 13, and the second limiting block 17; insert the left end of the oil pipe into the cavity of the first limiting block 10, loosen the tightening bolt 9, use the fork 82 at the front end of the tightening block 8 to help clamp and position the left end of the oil pipe, then tighten the tightening bolt 9 to lock the rear end of the tightening block 8; press the right section of the oil pipe hose through the clamp 15, and then place the right end of the oil pipe into the cavity groove of the second limiting block 17;

[0071] 5) Compare with equidistant line 18; check the tubing routing dimensions and accuracy by combining the limiting shape of each section, node and end of the tubing, as well as the degree of fit.

[0072] Based on the embodiments of this utility model described above, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this utility model.
