Description

Technical Field

[0001] This utility model relates to the technical field of external ball cage detection devices, and more specifically to a fault-prevention inspection tool for rapid and automatic sorting of missing external ball cages during machining. Background Technology

[0002] The outer CV joint is a component in an automotive transmission system used to transmit power and perform steering functions. Therefore, the precision requirements for the outer CV joint after production are extremely high. This is determined by its key role in the automotive transmission system and its working environment and performance requirements. Machining can ensure that the dimensional accuracy of each part of the outer CV joint meets the design requirements through precise tool control and cutting parameter adjustment. Taking the bell-shaped shell of the outer CV joint as an example, machining can effectively control the roundness and other shape tolerances of the outer surface of the bell-shaped shell, making its cylindrical surface meet the specified roundness requirements, and ensuring the stability and reliability of the outer CV joint during assembly and use.

[0003] Product inspection is a necessary step after the outer CVT car is machined to determine whether the machining quality meets assembly requirements. Currently, there are many types of inspection tools available on the market for outer CVT machining inspection. For example, the outer CVT pin hole and keyway inspection device disclosed in Chinese Patent Publication No. CN215373849U mainly uses a laser monitor to achieve comprehensive inspection of pin holes and keyways with a single laser scan, saving inspection time. Furthermore, if any pin holes or keyways are missed, the position of the missed pin holes can be detected and output by rotating the support turntable, reducing the labor intensity of employees and avoiding... To avoid missed or incorrect judgments due to fatigue and improve detection efficiency; in addition, Chinese Patent No. CN208818151U discloses an outer ball cage coaxiality detection device. This detection device is used to detect the coaxiality of the outer ball cage. That is, the inner circle of the outer ball cage is clamped by a three-jaw chuck, and then the A end is used as the reference plane. By measuring the coaxiality of the tail shaft relative to the reference A, it is also possible to detect whether the workpiece is eccentric. The position of the eccentricity can be determined by the numbers on the scale. Based on this data, the forging die can be changed in time to prevent the same eccentricity problem from occurring in the outer ball cages forged in the future.

[0004] However, during the machining of outer CV joints, due to various factors such as imperfect process design, unreasonable process arrangement, and operator negligence, some outer CV joints are often missed during machining. The aforementioned inspection tools and other inspection tools on the market used for the quality of outer CV joint machining cannot automatically sort out these missed outer CV joints. They need to be manually compared one by one. The long sorting process can easily cause operator fatigue, resulting in a decrease in sorting efficiency and difficulty in meeting the large-scale inspection needs of outer CV joints. Furthermore, sorting is easily affected by subjective experience factors, affecting the accuracy of sorting results. At the same time, the expenditure of labor costs is also high. Utility Model Content

[0005] To address the above issues, existing external ball cage processing inspection tools cannot sort out the missed processing parts of the external ball cages. Manual comparison is required, which is time-consuming and easily leads to operator fatigue, resulting in decreased sorting efficiency. Furthermore, the tools are susceptible to subjective experience, leading to low accuracy and high labor costs. The purpose of this invention is to provide an error-proofing inspection tool that can automatically sort the missed processing external ball cages without manual intervention, thus achieving high sorting efficiency and accuracy while also reducing costs.

[0006] To achieve the above objectives, the technical solution of this utility model is:

[0007] A fault-prevention inspection tool for rapid automatic sorting of missing parts in the processing of outer ball cages includes a base, a column, a balance bar, a stop arm, and a locking assembly. The column is placed on the base, the balance bar is placed on the column, and the stop arms are arranged sequentially along the length of the balance bar. Each stop arm includes a rotating rod and a separating block. A rotating hole is opened on the outer wall of the balance bar corresponding to the rotating rod. The upper end of the rotating rod is inserted into the rotating hole and rotatably connected to the balance bar. The separating block is located at the lower end of the rotating rod. A first locking hole is also opened on the outer wall of the balance bar. The first locking hole is opposite to and communicates with the rotating hole. The locking assembly is movably disposed in the first locking hole and is detachably engaged with the rotating rod.

[0008] Preferably, the separating block includes a base and a separating portion, the separating portion being formed at both ends of the base, and the separating portion having a wedge-shaped shape.

[0009] Preferably, the corners of the separation section and the joint with the base are rounded.

[0010] Preferably, a guide groove is provided on the outer wall of the column, the balance bar is inserted into the guide groove and slides with the column, and a second locking hole is also provided on the outer wall of the column. The second locking hole is opposite to and connected to the guide groove, and the locking component is also movably disposed in the second locking hole and detachably engaged with the balance bar.

[0011] Preferably, the locking assembly includes a first locking bolt, and a first internal thread is provided on the inner wall of the first locking hole. The first locking bolt and the first internal thread cooperate with each other and abut against the rotating rod.

[0012] Preferably, the locking assembly further includes a second locking bolt, and a second internal thread is provided on the inner wall of the second locking hole. The second locking bolt and the second internal thread cooperate with each other and abut against the balance bar.

[0013] Preferably, the number of stop arms is two sets.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] This utility model inspection fixture, by disassembling the locking assembly from the rotating rod of the stop arm, allows the stop arm to rotate freely in the rotating hole of the balance bar via its rotating rod, thereby driving the lower separating block to rotate. This changes the distance between the separating blocks of adjacent stop arms, and adjusts it to a suitable distance according to the size of the machined outer ball cage. Then, the locking assembly is controlled to lock the rotating rod, maintaining the adjusted distance between adjacent separating blocks. When the outer ball cage is conveyed between adjacent stop arms, the machined outer ball cage can pass smoothly, while the unmachined outer ball cage will be intercepted. This allows operators to intuitively, quickly, and accurately identify the missed machined outer ball cages, which significantly improves sorting efficiency and can effectively meet the needs of large-scale outer ball cage inspection, while also controlling labor costs.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, this utility model relates to a rapid and automatic error-proofing inspection tool for sorting out missing outer ball cages during machining. It includes a base 1, a column 2, a balance bar 3, stop arms 4, and a locking assembly 5. The column 2 stands on the base 1, and the balance bar 3 is mounted on the column 2. The balance bar 3 is supported upwards from the base 1 by the column 2 and extends outwards along its length. Multiple stop arms 4 are arranged along the length of the balance bar 3, with a certain interval between them. This interval allows the machined outer ball cage 6 to pass through. The outer ball cage 6 can be transported via a conveyor belt or other means. The conveying device automatically transports materials, simplifying the manual operation process. Each stop arm 4 includes a rotating rod 401 and a separating block 402. A rotating hole 301 is provided on the outer wall of the balance bar 3 corresponding to the rotating rod 401. The center line of the rotating hole 301 is perpendicular to the horizontal plane, meaning that the rotating hole 301 is connected to at least one end face of the upper or lower end face of the balance bar 3. The upper end of the rotating rod 401 is inserted into the rotating hole 301, allowing it to rotate within the hole and achieve a rotatable connection with the balance bar 3. The separating block 402 is located at the lower end of the rotating rod 401, so it can be driven to rotate when the rotating rod 401 rotates, thereby changing its orientation. Furthermore, the distance between the separator block 402 of the adjacent stop arm 4 will change synchronously. A first locking hole 302 is also provided on the outer wall of the balance bar 3. The first locking hole 302 is opposite to and connected to the rotating hole 301. The locking component 5 is movably disposed in the first locking hole 302 and is detachably engaged with the rotating rod 401. The locking component 5 can be separated from the rotating rod 401 by moving along the first locking hole 302, thereby completing the disassembly. After the locking component 5 is disassembled from the rotating rod 401 of the stop arm 4, the stop arm 4 can rotate freely in the rotating hole 301 of the balance bar 3 through its rotating rod 401, thereby driving the lower separator block 402 to rotate. The spacing between the separating blocks 402 of the adjacent stop arm 4 will change and be adjusted to a suitable spacing according to the size of the machined outer ball cage 6. Then, the locking assembly 5 is controlled to lock the rotating rod 401 to maintain the adjustable spacing between the adjacent separating blocks 402. When the outer ball cage 6 is conveyed between the adjacent stop arms 4, the machined outer ball cage 6 will be able to pass smoothly, while the unmachined outer ball cage 6 will be intercepted. This makes it convenient for operators to intuitively, quickly and accurately identify the missed machined outer ball cage 6. This can significantly improve the sorting efficiency and effectively meet the large-scale inspection needs of outer ball cage 6, while also controlling labor costs.

[0028] like Figure 6As shown, the separating block 402 consists of two parts: a base 402a and a separating part 402b. The base 402a is located in the middle of the entire separating block 402, and the separating part 402b is formed at both ends of the base 402a. The shape of the separating part 402b is wedge-shaped, which makes the shape of the separating block 402 a conical shape with both ends converging. In this utility model, the side of the separating part 402b is an arc edge, which can also be designed as a bevel edge. Thus, when the outer ball cage 6 passes between the separating blocks 402 of the adjacent stop arm 4, it can guide the machined outer ball cage 6, so that this part of the machined outer ball cage 6 can pass smoothly and avoid scratching the surface of the outer ball cage 6.

[0029] like Figure 6 As shown, the corners of the separation section 402b and the mating position with the base 402a are rounded, which further protects the machined outer ball cage 6 that passes through.

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, a guide groove 201 is provided on the outer wall of the column 2. The guide groove 201 is a through groove structure that is connected to the outer wall of the column 2 in two directions. The balance bar 3 is inserted into the guide groove 201 and slides with the column 2. In this way, the horizontal position of each connected stop arm 4 can be changed by sliding the balance bar 3. This can better maintain the relative position with the conveying path of the automatic conveying device and ensure that the outer ball cage 6 can accurately pass through the separation block 402 of the adjacent stop arm 4. A second locking hole 202 is also provided on the outer wall of the column 2. The second locking hole 202 is opposite to and connected to the guide groove 201. The locking component 5 is also movably installed in the second locking hole 202 and is detachably engaged with the balance bar 3. Under normal conditions, the balance bar 3 can be disassembled by moving the locking component 5 along the second locking hole 202, thereby releasing the lock on the balance bar 3 and allowing it to slide freely.

[0031] like Figures 1 to 5 as well as Figure 7 As shown, the locking assembly 5 includes a first locking bolt 501. A first internal thread 302a is provided on the inner wall of the first locking hole 302. The first locking bolt 501 and the first internal thread 302a cooperate with each other and abut against the rotating rod 401. The threaded connection is a detachable connection method, which allows the first locking bolt 501 to be separated from the rotating rod 401 by a simple rotation action, thereby realizing disassembly and making control more convenient. At the same time, when it is tightened, the self-locking property of the threaded connection will make the first locking bolt 501 and the rotating rod 401 fit tightly against each other, thereby effectively keeping the rotating rod 401 and the lower end connected separation block 402 in the adjustment position, improving the stability of the fixation.

[0032] like Figures 1 to 5 as well as Figure 7 As shown, the locking assembly 5 also includes a second locking bolt 502. A second internal thread 202a is provided on the inner wall of the second locking hole 202. The second locking bolt 502 and the second internal thread 202a cooperate with each other and abut against the balance bar 3. Based on the threaded connection between the second locking bolt 502 and the internal thread of the second locking hole 202, it has the same effect as the first locking bolt 501 mentioned above, so it will not be described in detail. This arrangement facilitates disassembly and locking of the balance bar 3.

[0033] Furthermore, there are two sets of stop arms 4. This setup will reduce the overall size of the inspection fixture while ensuring the correct implementation of the automatic sorting function, thus facilitating installation.

[0034] Combination Figures 1 to 7 The inspection tool of this utility model can be used in conjunction with a conveyor belt or other conveying device to enable automatic conveying of the outer ball cage 6. The inspection tool is mounted on one side of the conveying device via the base 1, so that the balance bar 3 can extend above the conveying device and keep each stop arm 4 above the conveying device. Furthermore, the second locking bolt 502 of the locking assembly 5 can be rotated to disengage it from the balance bar 3, thus controlling the movement of the balance bar 3 to further adjust the position of the stop arms 4. Afterwards, tighten the second locking bolt 502 and rotate the first locking bolt 501 of the locking assembly 5 to disengage it from the rotating rod 401. To achieve disassembly, the angle of the lower separating block 402 can be adjusted by rotating the lever 401 of the stop arm 4. This will change the distance between the separating blocks 402 of adjacent stop arms 4. The distance can be adjusted to a suitable distance according to the size of the machined outer ball cage 6. Then, the first locking bolt 501 is tightened to lock the lever 401, maintaining the adjustable distance between adjacent separating blocks 402. When the outer ball cage 6 is conveyed between adjacent stop arms 4, the machined outer ball cage 6 can pass smoothly, while the unmachined outer ball cage 6 will be intercepted. This allows the operator to intuitively, quickly and accurately identify the missing machined outer ball cage 6.

[0035] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
