Description

Technical Field

[0001] This utility model relates to the field of automotive mechanical technology, and in particular to a steering intermediate shaft detection device. Background Technology

[0002] The intermediate steering shaft of an automobile connects to the steering column and steering gear at both ends, respectively, via spline assembly and bolt tightening. Because the connections between the steering column and chassis steering gear vary between different vehicle models, the interface dimensions and phase angles of the left and right end forks of the intermediate shaft differ significantly. Without an effective testing method, customers may be unable to install the assembly.

[0003] However, traditional detection methods are cumbersome to operate and have low detection efficiency. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution; A phase angle inspection and interface testing device for a steering intermediate shaft, including a testing system for testing the intermediate shaft assembly, wherein the intermediate shaft assembly is provided with two splines at both ends, and the testing system includes a fixed base for mounting the steering intermediate shaft; The detection system includes a first fixed seat and a second fixed seat for mounting the intermediate shaft assembly, wherein the first fixed seat is mounted on a fixed base. The first fixed seat is connected to one end of the steering intermediate shaft, and the second fixed seat is connected to the other end of the steering intermediate shaft; The detection system also includes a slide rail and a sliding plate that slides along the slide rail, and the second fixed seat is mounted on the sliding plate; The detection system includes a first forked spline go / no-go gauge and a second forked spline go / no-go gauge, which are mounted on a fixed base. The first forked spline go / no-go gauge is inserted into one end of the intermediate shaft assembly to detect the spline at one end of the intermediate shaft assembly. The second forked spline go / no-go gauge faces the other end of the intermediate shaft assembly. The sliding plate drives the other spline of the intermediate shaft assembly to insert into the second forked spline go / no-go gauge through the second fixed seat to detect the intermediate shaft assembly.

[0007] The above design integrates the original two-spline inspection of the intermediate shaft assembly into a single workstation, completed in one clamping operation by the inspection system. The operator only needs to load the intermediate shaft assembly and push the sliding plate to automatically complete the insertion inspection of the splines at both ends, significantly improving inspection efficiency. The first fork spline go / no-go gauge is inserted into the spline at one end of the intermediate shaft assembly, and the sliding plate drives the intermediate shaft assembly to insert the spline at the other end into the second fork spline go / no-go gauge, thus completing the interface inspection. The phase angle of the intermediate shaft assembly is indirectly measured by measuring the relative positions of the first and second fork spline go / no-go gauges at both ends. The unified benchmark and mechanically driven inspection process avoid the influence of individual operational differences on the inspection results.

[0008] Preferably, each of the two splines is provided with two threaded fastening holes, and each of the two threaded fastening holes is provided with two openings. The detection system also includes two thread go / no-go gauges, which are used to detect the two threaded fastening holes. The system detects whether the two thread go / no-go gauges can pass smoothly and whether the threads of the two splines are qualified.

[0009] Preferably, the fixed base is further provided with a positioning seat, and the positioning seat is provided with a threaded hole; The positioning seat is located near the first fixed seat. When the first fork spline go / no-go gauge is inserted into the spline at one end of the intermediate shaft assembly, a threaded fastening hole on the spline aligns with the threaded hole of the positioning seat. The threaded go / no-go gauge passes through the aligned threaded fastening hole and is screwed into the threaded hole of the positioning seat to fix one end of the intermediate shaft assembly. The threaded go / no-go gauge rigidly connects the spline at one end of the intermediate shaft assembly to the positioning seat of the base, effectively anchoring the intermediate shaft assembly to the testing platform. This eliminates the slight displacement or wobbling that may occur in the entire workpiece system when the sliding plate is pushed, providing an absolutely stable reference zero point for the phase angle detection at the other end. Each test uses the same positioning seat as a reference, ensuring the consistency and comparability of test results for different workpieces and different shifts.

[0010] Preferably, the detection system is provided with a first mounting base and a second mounting base, which are respectively located at both ends of the intermediate shaft assembly. The first mounting base is mounted on a fixed base, and the second mounting base is mounted on the sliding plate. The first mounting base is provided with a first through groove, the position of which is directly opposite the opening position of the spline on the positioning base. The first fork spline go / no-go gauge is provided with a first protrusion that slides along the first through groove. The first protrusion gets stuck in the opening when the first fork spline go / no-go gauge is inserted into the spline. The second mounting base is provided with a second through groove, which is positioned directly opposite the opening of the spline on the sliding plate. The second fork spline go / no-go gauge is provided with a second protrusion that slides along the second through groove. When the second fork spline go / no-go gauge is inserted into another spline, the second protrusion gets stuck in another opening. The phase angle is detected by measuring the relative positions of the first and second protrusions in their respective through grooves. The operator does not need to use a complex angle gauge or coordinate measuring machine; by observing or simply measuring the relative positions of the protrusions and the groove openings, the phase angle can be quickly determined to be qualified or not. The mechanical structure of the first through groove, the second through groove, the first protrusion, and the second protrusion is extremely simple, inexpensive, and not easily damaged, avoiding the drift and malfunction problems that may be caused by electronic sensors, making it suitable for long-term stable use on the production line.

[0011] Preferably, the two ends of the intermediate shaft assembly are connected to two splines via two universal joints; The fixed base also includes a first fixed seat, a second fixed seat and a third fixed seat, with the first fixed seat disposed on the fixed base; The second and third fixing seats are mounted on the sliding plate, and the second and third fixing seats are respectively disposed on both sides of the universal joint on the sliding plate.

[0012] Preferably, a first clamping block for clamping the steering intermediate shaft is provided above the first fixed seat, and the first clamping block is connected to the fixed base by bolts; A second clamping block is provided above the second fixed seat to clamp the steering intermediate shaft. The second clamping block is connected to the sliding plate by bolts to the second fixed seat. A third clamping block for pressing the steering intermediate shaft is provided above the third fixed seat, and the third clamping block is connected to the sliding plate by bolts.

[0013] The intermediate shaft assembly, equipped with a universal joint, is a flexible component. If only the two ends are clamped, the middle section will sag or twist due to its own weight or the testing force, leading to distorted test results. The first, second, and third fixed seats, along with the first, second, and third clamping blocks, ensure a fixed posture during testing, maintaining a constant relative angle between the splines at both ends. The first mounting seat is used to pass through the first fork spline go / no-go gauge, and the second mounting seat is used to pass through the second fork spline go / no-go gauge, ensuring the authenticity of the test data and preventing qualified products from being mistakenly identified as unqualified.

[0014] Preferably, the fixed base is provided with a first positioning strip, and the bottom of the first fixed base is provided with a first positioning groove that cooperates with the first positioning strip; The sliding plate is provided with a second positioning strip, and the second fixed seat is provided with a second positioning groove that cooperates with the second positioning strip below it. A third positioning groove that mates with the first positioning strip is provided below the first fixing seat; The second and third fixed seats are provided with a fourth positioning groove below them, which cooperates with the second positioning strip.

[0015] The engagement of the first positioning strip with the first and third positioning slots, and the engagement of the second positioning strip with the second and fourth positioning slots, ensures that the connecting seat and the fixing seat return to their original positions after each disassembly and reinstallation. This guarantees that even if the intermediate shaft assembly is replaced with one from a different vehicle model, the baseline of the entire testing system remains unchanged. When the production line needs to test different models of intermediate shafts, only the corresponding connecting seat, fixing seat, and clamping block assembly need to be replaced, achieving multi-purpose functionality and greatly improving the equipment's versatility.

[0016] Preferably, the first fork spline go / no-go gauge is fixedly mounted on the fixed base, and the second fork spline go / no-go gauge is mounted on the fixed base via a clamping device. Loosening the clamping device allows adjustment of the second fork spline go / no-go gauge's position on the fixed base; after adjustment, it is clamped again. Different vehicle models have different intermediate shaft lengths. By designing the second go / no-go gauge to be position-adjustable, one testing device can cover multiple models, eliminating the need to customize a dedicated device for each length specification.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in less than one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0023] refer to Figure 1 The device for checking the phase angle and interface of the steering intermediate shaft includes a detection system for detecting the intermediate shaft assembly 1. The intermediate shaft assembly 1 has two splines at both ends. The detection system includes a fixed base 2 for mounting the steering intermediate shaft.

[0024] The detection system includes a first fixed seat 31 and a second fixed seat 32 for mounting the intermediate shaft assembly 1. The first fixed seat 31 is mounted on the fixed base 2. The first fixed seat 31 is connected to one end of the steering intermediate shaft, and the second fixed seat 32 is connected to the other end of the steering intermediate shaft; The detection system also includes a slide rail 21 and a sliding plate 4 that slides along the slide rail 21, and a second fixed seat 32 is mounted on the sliding plate 4; The detection system includes a first fork spline go / no-go gauge 51 and a second fork spline go / no-go gauge 52, which are mounted on a fixed base 2. The first forked spline go / no-go gauge 51 is inserted into one end of the intermediate shaft assembly 1 to detect the spline at one end of the intermediate shaft assembly 1. The second forked spline go / no-go gauge 52 faces the other end of the intermediate shaft assembly 1. The sliding plate 4 drives the other spline of the intermediate shaft assembly 1 to be inserted into the second forked spline go / no-go gauge 52 through the second fixed seat 32 to detect the intermediate shaft assembly 1.

[0025] The above design integrates the original two-spline inspection of the intermediate shaft assembly 1 into a single workstation, completed in one clamping operation by the inspection system. The operator only needs to load the intermediate shaft assembly 1 and push the sliding plate 4 to automatically complete the insertion inspection of the splines at both ends, significantly improving inspection efficiency. The first fork spline go / no-go gauge 51 is inserted into the spline at one end of the intermediate shaft assembly 1, and the sliding plate 4 drives the intermediate shaft assembly 1 to insert the spline at the other end into the two-fork spline go / no-go gauge, thus completing the interface inspection. The phase angle of the intermediate shaft assembly 1 is indirectly measured by measuring the relative positions of the first fork spline go / no-go gauge 51 and the two-fork spline go / no-go gauge at both ends. The unified benchmark and mechanically driven inspection process avoid the influence of individual operational differences on the inspection results.

[0026] Each of the two splines has two threaded fastening holes, and each of the two threaded fastening holes has two openings. The inspection system also includes two thread go / no-go gauges 6, which are used to inspect the two threaded fastening holes. The system checks whether the two thread go / no-go gauges 6 can pass smoothly and whether the threads of the two splines are up to standard.

[0027] The fixed base 2 is also equipped with a positioning seat 8, which has a threaded hole. The positioning seat 8 is located on the side close to the first fixed base 31. When the first fork spline go / no-go gauge 51 is inserted into the spline at one end of the intermediate shaft assembly 1, a threaded fastening hole on the spline aligns with the threaded hole of the positioning seat 8. A threaded go / no-go gauge 6 passes through the aligned threaded fastening hole and is screwed into the threaded hole of the positioning seat 8 to fix one end of the intermediate shaft assembly 1. The threaded go / no-go gauge 6 rigidly connects the spline at one end of the intermediate shaft assembly 1 to the positioning seat 8 of the base, which is equivalent to anchoring the intermediate shaft assembly 1 on the detection platform. This eliminates the slight displacement or shaking that may occur in the entire workpiece system when the sliding plate 4 is pushed, and provides an absolutely stable reference zero point for the phase angle detection at the other end. Each detection is based on the same positioning seat 8, ensuring the consistency and comparability of detection results for different workpieces and different shifts.

[0028] The detection system is equipped with a first mounting base and a second mounting base, which are respectively located at both ends of the intermediate shaft assembly. The first mounting base is mounted on the fixed base, and the second mounting base is mounted on the sliding plate 4. The first mounting base is provided with a first through groove, the position of which is directly opposite the opening position of the spline on the positioning base 8. The first fork spline go / no-go gauge 51 is provided with a first protrusion that slides along the first through groove. The first protrusion gets stuck in the opening when the first fork spline go / no-go gauge 51 is inserted into the spline. The second mounting base is provided with a second through groove, which is positioned directly opposite the opening of the spline on the sliding plate 4. The second fork spline go / no-go gauge 52 is provided with a second protrusion that slides along the second through groove. When the second fork spline go / no-go gauge 52 is inserted into another spline, the second protrusion gets stuck in another opening. The phase angle is detected by measuring the relative positions of the first and second protrusions in their respective through grooves. The operator does not need to use a complex angle gauge or coordinate measuring machine; by observing or simply measuring the relative positions of the protrusions and the groove openings, the phase angle can be quickly determined to be qualified or not. The mechanical structure of the first through groove, the second through groove, the first protrusion, and the second protrusion is extremely simple, inexpensive, and not easily damaged, avoiding the drift and malfunction problems that may be caused by electronic sensors, making it suitable for long-term stable use on the production line.

[0029] The intermediate shaft assembly 1 is connected to two splines at both ends by two universal joints; the fixed base also includes a first fixed seat 71, a second fixed seat 72 and a third fixed seat 73, the first fixed seat 71 is disposed on the fixed base; the second fixed seat 72 and the third fixed seat 73 are mounted on the sliding plate 4, and the second fixed seat 72 and the third fixed seat 73 are respectively disposed on both sides of the universal joint on the sliding plate 4.

[0030] A first clamping block for pressing the steering intermediate shaft is provided above the first fixed seat 71, and the first clamping block is connected to the first fixed seat 71 by bolts to the fixed base; a second clamping block for pressing the steering intermediate shaft is provided above the second fixed seat 72, and the second clamping block is connected to the second fixed seat 72 by bolts to the sliding plate 4; a third clamping block for pressing the steering intermediate shaft is provided above the third fixed seat 73, and the third clamping block is connected to the third fixed seat 73 by bolts to the sliding plate 4.

[0031] The intermediate shaft assembly 1 has a universal joint and is a flexible body. If only the two ends are clamped, the middle part will sag or twist due to its own weight or the testing force, resulting in distorted test results. Through the first fixing seat 71, the second fixing seat 72, the third fixing seat 73, and the first clamping block, the second clamping block, and the third clamping block, it maintains a fixed posture during testing, and the splines at both ends maintain a fixed relative angle, ensuring the authenticity of the test data and avoiding misjudging qualified products as unqualified products.

[0032] In use, the intermediate shaft assembly 1 is placed on the first fixed seat 71, the second fixed seat 72, and the third fixed seat 73. The first forked spline go / no-go gauge 51 is inserted into the spline at one end of the intermediate shaft, so that its first protrusion engages with the spline opening. A threaded go / no-go gauge 6 is passed through the aligned spline threaded hole and screwed into the threaded hole of the positioning seat 8 of the base. This simultaneously completes the inspection of the threaded hole at one end of the intermediate shaft assembly 1 and establishes a rigid reference. Then, it is pressed down with the first clamping block, the second clamping block, and the third clamping block, and then fixed with bolts. Pushing the sliding plate 4 drives the intermediate shaft assembly 1 to move, so that the other spline at the other end is inserted into the second forked spline go / no-go gauge 52, and the second protrusion engages with the spline opening. If both splines can be smoothly and without jamming into their respective go / no-go gauges, the spline interface dimensions are qualified. At this time, the circumferential position difference between the first and second protrusions in their respective through grooves is within the tolerance range, and the phase angle is qualified. Example

[0033] refer to Figure 1 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] The fixed base 2 is provided with a first positioning strip, and the first mounting base 31 is provided with a first positioning groove that cooperates with the first positioning strip below it; The sliding plate 4 is provided with a second positioning strip, and the second mounting base 32 is provided with a second positioning groove that cooperates with the second positioning strip below it; A third positioning groove that mates with the first positioning strip is provided below the first fixed base 71; The second fixing seat 72 and the third fixing seat 73 are provided with a fourth positioning groove that cooperates with the second positioning strip.

[0035] The engagement of the first positioning strip with the first and third positioning slots, and the engagement of the second positioning strip with the second and fourth positioning slots, ensures that the connecting seat and the fixed seat return to their original positions after each disassembly and reinstallation. This guarantees that even if the intermediate shaft assembly 1 is replaced with one from a different vehicle model, the baseline of the entire inspection system will not change. When the production line needs to inspect different models of intermediate shafts, only the corresponding connecting seat, fixed seat, and clamping block assembly need to be replaced, achieving multi-purpose functionality and greatly improving the equipment's versatility.

[0036] The first fork spline go / no-go gauge 51 is fixedly mounted on the fixed base 2. The second fork spline go / no-go gauge 52 is mounted on the fixed base 2 via a clamping device. Loosening the clamping device allows adjustment of the position of the second fork spline go / no-go gauge 52 on the fixed base 2. After adjustment, it is clamped again. The intermediate shaft assembly 1 varies in length for different vehicle models. By designing the second go / no-go gauge to be position-adjustable, one testing device can cover multiple models, eliminating the need to customize a dedicated device for each length specification.

[0037] During use, loosen the fasteners of each fixed seat and the second fork spline go / no-go gauge 52. Align and tighten the first fixed seat 71, second fixed seat 72, and third fixed seat 73, along with the first clamping block, second clamping block, and third clamping block, using the engagement of the first positioning strip and the first positioning groove at their bottom, and the engagement of the second positioning strip and the second positioning groove and the third positioning groove, with the first positioning strip on the base and the second positioning strip on the sliding plate 4. Adjust the position of the second fork spline go / no-go gauge 52 on the base according to the length of the intermediate shaft assembly 1 of the new model, and then lock it using the clamping device. This allows one testing device to cover multiple models, eliminating the need to customize a testing device for each length specification.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
