Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection technology, and in particular to a rear lower control arm bushing position detection device. Background Technology

[0002] In the automotive manufacturing industry, the rear lower control arm is a key component of the chassis suspension system, and its performance directly affects the vehicle's handling stability and driving safety. The rear lower control arm bushing plays an important role in buffering, damping, and adjusting stress, and its positional accuracy has a profound impact on the functionality of the control arm and even the entire suspension system.

[0003] Currently, in the automotive parts manufacturing process, the inspection of the rear lower control arm bushing position largely relies on traditional coordinate measuring machines (CMMs). While this method provides relatively accurate measurement data, the inspection process is cumbersome, requires specialized technicians, is time-consuming, and inefficient, making it difficult to meet the real-time inspection needs of large-scale, high-efficiency production lines. Furthermore, CMMs are expensive and require complex maintenance, further increasing production costs and management difficulties for companies.

[0004] In addition, some companies use manual inspection, employing simple measuring tools such as calipers and rulers to measure the bushing position. However, manual inspection is highly susceptible to subjective factors; different inspectors have different operating techniques and judgment standards, which can easily lead to measurement errors and make it difficult to guarantee the consistency and accuracy of the test results, thereby affecting the stability of product quality. During the production process, if bushing position deviations are not detected in time and flow into subsequent processes, it may cause assembly problems in the entire vehicle, resulting in serious consequences such as abnormal vibrations, uneven tire wear, and decreased handling performance. This not only increases the risk of product recalls but also damages the company's brand image and market reputation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a rear lower control arm bushing position detection device.

[0006] Therefore, this utility model provides a rear lower control arm bushing position detection device, including a base, on which multiple detection seats are fixedly installed. The detection seats include a rear lower control arm inner hole detection seat, a left bushing detection seat, a right bushing detection seat, and an ear bushing detection seat. All the detection seats are provided with detection pins. The detection pins are used to detect the size and spatial position of the rear lower control arm inner hole, the left bushing, the right bushing, and the ear bushing. The left bushing detection seat is provided with a clamping device for clamping the left bushing.

[0007] Preferably, the left bushing detection seat includes a first fixed seat, a second fixed seat, and a fixed plate. The fixed plate and the first fixed seat are arranged in parallel and connected by the second fixed seat. The height of the second fixed seat is lower than the height of the first fixed seat and the fixed plate. A clamping area is formed between the first fixed seat, the second fixed seat, and the fixed plate. The left bushing is placed in the clamping area and clamped by the clamping device.

[0008] Preferably, the clamping device includes a clamping bolt and a positioning adjustment component. The clamping bolt is threadedly connected to the fixing plate and passes through the fixing plate. A pressure plate is fixedly installed at the tail end of the clamping bolt. The positioning adjustment component is disposed on the fixing seat and is used to adjust the clamping position of the left bushing. The left bushing abuts against the positioning adjustment component through the pressure plate.

[0009] Preferably, the positioning adjustment component includes a sleeve, a retaining ring, and a tightening bolt. The sleeve is slidably mounted on the upper part of the first fixing seat. The retaining ring is fixedly mounted on the end of the sleeve away from the clamping area. The outer diameter of the retaining ring is larger than the outer diameter of the sleeve, and the inner diameter of the retaining ring is the same as the inner diameter of the sleeve. An elongated groove is formed at the top of the sleeve, and a threaded hole is formed at the top of the first fixing seat. The position of the groove corresponds to the position of the threaded hole. The tightening bolt is threadedly connected to the threaded hole and presses against the sleeve. The clamping bolt presses the left bushing onto the sleeve.

[0010] Preferably, the bottom of the sleeve has a planar structure.

[0011] Preferably, a plurality of limiting teeth are fixedly installed at one end of the sleeve located in the clamping area, and a limiting space is formed between two adjacent limiting teeth. A plurality of protruding rods are fixedly installed at one end of the left bushing, and the protruding rods are adapted to be inserted into the limiting space.

[0012] Preferably, an annular groove is formed between the fixing ring, the fixing seat, and the sleeve. A rotating rod is rotatably mounted on the fixing seat on the same side of the fixing ring via a rotating shaft. The rotating rod is engaged in the annular groove to limit the movement distance of the sleeve.

[0013] Preferably, a limiting pin is provided on the fixed base, and the limiting pin is used to limit the position of the rotating rod.

[0014] Preferably, the rotating rod is bent at the pivot, and the two bent parts are distributed at an obtuse angle.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a rear lower control arm bushing position detection device, which has the following beneficial effects.

[0016] The lower rear control arm equipped with the bushing is placed on the corresponding inspection seat. The left bushing is clamped using a clamping device. After the left bushing is fixed, multiple inspection pins are inserted into the corresponding bushing and the inner hole of the lower rear control arm to inspect the size and spatial position. This allows for a quick determination of whether the product meets customer requirements in terms of size and spatial position, improving inspection efficiency, reducing inspection costs, reducing measurement errors caused by manual measurement, ensuring product quality stability, and reducing the risk of product recall.

[0017] Based on the different specifications of the left bushing, determine the width of the rotating rod, install the appropriate size rotating rod on the fixed base, rotate the rotating rod to insert its side into the annular groove, and then use the tightening bolt to fix the position of the sleeve, thereby ensuring that the end of the sleeve extending out of the clamping area meets the inspection requirements of the bushing of that specification. Then rotate the clamping bolt to make the pressure plate in the clamping area push the protruding rod on the left bushing into the corresponding limiting space and press it, preventing the position of the corresponding bushing from rotating during the bushing inspection, ensuring the smooth progress of the bushing spatial position inspection work, and meeting the inspection needs of bushings of different specifications.

[0018] The setting of the limit pin can effectively limit the position of the rotating rod, so that it is always locked in the annular groove, preventing the rotating rod from rotating when the sleeve is fixed, thereby affecting the accuracy of the detection dimensions;

[0019] The bottom of the sleeve is designed with a flat structure, which facilitates cooperation with the tightening bolt and allows for better fixation of the sleeve, resulting in a good fixing effect. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Example:

[0030] like Figures 1 to 7 As shown, this utility model provides a rear lower control arm bushing position detection device, including a base 1. Multiple detection seats are fixedly installed on the base 1. The detection seats include a rear lower control arm inner hole detection seat 2, a left bushing detection seat 3, a right bushing detection seat 4, and an ear bushing detection seat 5. The left bushing detection seat 3 and the ear bushing detection seat 5 are both located on the left side of the base 1, and the right bushing detection seat 4 is located on the right side of the base 1. The rear lower control arm inner hole detection seat 2 is located between the left bushing detection seat 3 and the right bushing detection seat 4. All the detection seats are provided with detection pins 6, which are used to insert into the rear lower control arm inner hole 7, left bushing 8, right bushing 9, and ear bushing 10 to detect their size and spatial position. The left bushing detection seat 3 is provided with a clamping device for clamping the left bushing 8.

[0031] Furthermore, the left bushing detection seat 3 includes a first fixing seat 31, a second fixing seat 32, and a fixing plate 33. The fixing plate 33 and the first fixing seat 31 are arranged in parallel and are fixedly connected by the second fixing seat 32. The height of the second fixing seat 32 is lower than the height of the first fixing seat 31 and the fixing plate 33. A concave rectangular clamping area 11 is formed between the first fixing seat 31, the second fixing seat 32, and the fixing plate 33. The left bushing 8 is placed in the clamping area 11 and clamped by the clamping device.

[0032] Furthermore, the clamping device includes a clamping bolt 12 and a positioning adjustment component. The clamping bolt 12 is threadedly connected to the fixing plate 33 and passes through the fixing plate 33. A pressure plate is fixedly installed at the tail end of the clamping bolt 12 (i.e., the end located within the clamping area 11). The positioning adjustment component is disposed on the fixing seat 31 and is used to adjust the clamping position of the left bushing 8. The left bushing 8 abuts against the positioning adjustment component through the pressure plate.

[0033] Furthermore, the positioning adjustment component includes a sleeve 13, a fixing ring 14, and a tightening bolt. The sleeve 13 is slidably mounted on the upper part of the fixing seat 31, facilitating the adjustment of the position of the sleeve 13 according to different specifications of the left bushing 8. The fixing ring 14 is fixedly mounted on the end of the sleeve 13 away from the clamping area 11. The outer diameter of the fixing ring 14 is larger than the outer diameter of the sleeve 13 to prevent the sleeve 13 from moving too far toward the clamping area 11, causing the sleeve 13 to detach from the fixing seat 31. The inner diameter of the fixing ring 14 is the same as the inner diameter of the sleeve 13, facilitating the insertion of the detection pin 6 for detection. The top of the sleeve 13 has an elongated groove 15, the bottom of which is closed. The top of the fixing seat 31 has a threaded hole 16, the position of which corresponds to the position of the groove 15. The tightening bolt is threadedly connected to the threaded hole 16 and presses against the groove 15 of the sleeve 13, thereby fixing the position of the sleeve 13. When testing the left bushing 8 of this specification, simply place the left bushing 8 in the clamping area 11 and use the clamping bolt 12 to press the left bushing 8 onto the sleeve 13. There is no need to readjust the position of the sleeve 13.

[0034] For fixing the sleeve 13, multiple matching round holes can be opened on the top of the sleeve 13 according to the different specifications of the left bushing 8. When the tightening bolt is inserted into the corresponding round hole, the position of the sleeve 13 can be effectively fixed to prevent the sleeve 13 from moving laterally.

[0035] Furthermore, the bottom of the sleeve 13 is a planar structure, which not only facilitates its cooperation with the tightening bolt to effectively fix the sleeve 13 with good fixing effect, but also prevents the sleeve 13 from rotating within the fixed seat 31, providing a good limiting and guiding effect.

[0036] Furthermore, a plurality of limiting teeth 17 are fixedly installed at one end of the sleeve 13 located in the clamping area 11, and a limiting space 18 is formed between two adjacent limiting teeth 17. A plurality of protruding rods 19 are fixedly installed at one end of the left bushing 8, and the protruding rods 19 are adapted to be inserted into the limiting space 18.

[0037] The setting of the limiting space 18 can prevent the left bushing 8 from rotating during the test, thus affecting the test results.

[0038] Furthermore, an annular groove 20 is formed between the fixing ring 14, the fixing seat 31, and the sleeve 13. A rotating rod 22 is rotatably mounted on the fixing seat 31 on the same side as the fixing ring 14 via a rotating shaft 21. The rotating rod 22 is inserted into the annular groove 20 to limit the movement distance of the sleeve 13.

[0039] According to the different specifications of the left bushing 8, the corresponding size of the rotating rod 22 is made. When the left bushing 8 of a certain specification is tested, the corresponding specification of the rotating rod 22 is selected and it is rotated and installed on the fixed seat 31 through the rotating shaft 21. Then, it is rotated to the position of the annular groove 20 so that it is inserted into the annular groove 20. The fixing ring 14 is pressed forward, and the position of the sleeve 13 is fixed by using the tightening bolt. In this way, the pressing position of the left bushing 8 can be precisely defined, ensuring the accuracy of the test.

[0040] Furthermore, a limiting pin 23 is provided on the fixed base 31, which is used to limit the position of the rotating rod 22.

[0041] When the rotating rod 22 is engaged in the annular groove 20, in order to prevent the rotating rod 22 from rotating outward and dislodging from the annular groove 20, a limiting pin 23 is inserted in the outward rotation direction of the rotating rod 22, so that the rotating rod 22 can always be engaged in the annular groove 20, preventing the rotating rod 22 from rotating when the sleeve 13 is fixed, thereby affecting the accuracy of the detection.

[0042] Furthermore, the rotating rod 22 is bent at the rotating shaft 21, and the two bent parts are distributed at an obtuse angle. The obtuse angle design can make reasonable use of the side space of the fixed seat 31, which is conducive to the quick insertion of the limiting pin 23 without interfering with the normal operation of the clamping test.

[0043] The working principle is as follows:

[0044] Select the corresponding specification of the rotating rod 22 in advance and install it on the fixed seat 31 by rotating the rotating shaft 21. Then rotate it to the position of the annular groove 20 so that it is inserted into the annular groove 20. Press the fixed ring 14 forward and use the tightening bolt to fix the position of the sleeve 13, so as to accurately limit the pressing position of the left bushing 8.

[0045] During testing, the lower rear control arm, pre-equipped with the corresponding bushings, is placed on the corresponding testing seat. First, the hole on the lower rear control arm passes through the inner hole testing seat 2 of the lower rear control arm. Then, the part with the left bushing 8, right bushing 9 and ear bushing 10 is placed on the corresponding left bushing testing seat 3, right bushing testing seat 4 and ear bushing testing seat 5. After the left bushing 8 is placed in the clamping area 11 of the left bushing testing seat 3, the clamping bolt 12 is rotated to drive the pressure plate to press inward, so that the protrusion 19 on the left bushing 8 is inserted into the corresponding limiting space 18 for pressing and fixing.

[0046] After fixing, the detection pin 6 of the left bushing 8 is inserted into the left bushing 8 through the fixing ring 14 and the sleeve 13 for detection. At the same time, the detection pin 6 of the inner hole 7 of the rear lower control arm is also inserted into the inner hole 7 of the rear lower control arm for detection. The detection pin 6 of the right bushing 9 is inserted into the right bushing 9 for detection. The two detection pins 6 of the ear bushing 10 are inserted from the outside into the corresponding ear positions for detection. Through the detection of the detection pins 6, it can be quickly determined whether the bushings assembled on the rear lower control arm meet the requirements.
