Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a detection tool with an out-of-tolerance detection function. Background Art

[0002] Stabilizer bars are components placed horizontally at the front and rear ends of a vehicle. Their working principle is based on their design. They are typically U-shaped and made of spring steel. Their primary function is to enhance vehicle stability, improve handling, and reduce tire wear. Specifically, stabilizer bars enhance vehicle stability by counteracting the lateral forces generated when the vehicle turns, limiting the body's roll angle. When a vehicle turns, the outer wheels experience greater lateral (centrifugal) forces, causing the vehicle to roll. Stabilizer bars counteract these lateral forces, reducing the amount of roll and maintaining better handling. Stabilizer bars also reduce tire wear caused by frequent directional changes during driving, thereby extending tire life. When the vehicle is traveling straight, the suspension on both sides experiences equal deformation, and the stabilizer bar is ineffective. However, when the vehicle turns, the body roll causes the suspension on both sides to oscillate unevenly, causing the outer suspension to press against the stabilizer bar, causing it to twist. The elastic force of the stabilizer bar prevents the wheels from lifting, thereby maintaining the vehicle's balance as much as possible and providing lateral stability.

[0003] There is a type of automobile stabilizer bar with a straight middle section and irregularly shaped curved ends. The ends of the stabilizer bar are flat. Two bushings need to be bonded to the ends of the straight middle section of the stabilizer bar. The stabilizer bar undergoes tempering before the bushings are bonded. After tempering, the stabilizer bar needs to be placed in a testing fixture to inspect the stabilizer bar to see if the diameter of the area on the stabilizer bar where the bushings are bonded meets the requirements. The stabilizer bar is flat at both ends and has a pin hole on each flat end. After the stabilizer bar is placed in the testing fixture, a pin needs to be inserted into the pin hole to position the two ends of the stabilizer bar. However, many workers, for the sake of convenience, do not press the two ends of the stabilizer bar. Furthermore, due to possible errors in the processing dimensions of the stabilizer bar, the end length of the stabilizer bar is too long, resulting in an out-of-tolerance length. Existing testing fixtures cannot detect this error in a timely manner, and as a result, non-compliant products cannot be discovered in a timely manner. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and to design a detection tool with an out-of-tolerance detection function, which solves the problem that the existing inspection tool cannot timely and accurately detect the out-of-tolerance of the end length of the stabilizer bar.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is a detection tool with an out-of-tolerance detection function, comprising:

[0006] A plurality of positioning members, wherein the distribution positions of the plurality of positioning members are adapted to the shape of the product to be inspected, and each positioning member has a first positioning groove adapted to the shape of the product to be inspected;

[0007] Two out-of-tolerance detection modules, each corresponding to the position of the two ends of the product to be detected, each including a positioning block and a pin capable of being plugged into the pin hole at the end of the product to be detected. The positioning block has a second positioning groove that matches the shape of the end of the product to be detected, and the pin is inserted into the positioning block;

[0008] The positioning block has a blocking member on one side close to the end face of the product to be tested, which closes one end of the second positioning groove, and the distance between the blocking member and the pin does not exceed the distance between the pin hole on the end of the qualified product and the end of the product.

[0009] Preferably, the detection tooling also includes a tooling plate and at least one coarseness detection module, the coarseness detection module includes a positioning base and a detection plate slidably arranged on the top of the positioning base, the positioning base has a third positioning groove that is adapted to the shape of the part for bonding the bushing on the product to be inspected, the depth of the third positioning groove is adapted to the diameter of the part for bonding the bushing on the product to be inspected, and the detection plate can seal the top opening of the third positioning groove.

[0010] Preferably, a mounting block is provided on one side of the positioning base, and a sliding groove is provided inside the mounting block for guiding the sliding of the detection plate.

[0011] Preferably, a handle is provided on the detection plate, a strip hole communicating with the slide groove is opened on the mounting block, and the handle passes through the strip hole.

[0012] Preferably, the positioning member includes a first positioning member, a second positioning member and a third positioning member. The first positioning member is arranged in the middle area of the tooling plate to position the middle section of the product to be inspected. The second positioning member and the third positioning member are provided at both ends of the tooling plate to position the two ends of the product to be inspected. There are two coarseness detection modules, and the first positioning member is located between the two coarseness detection modules.

[0013] Preferably, one end of the second positioning groove on the positioning block extends vertically upward to form a blocking portion, so that one end of the second positioning groove is through and the other end is not through.

[0014] A blocking plate is installed on one side of the positioning block, and the blocking plate closes one end of the second positioning groove.

[0015] Compared with the prior art, the beneficial effects are:

[0016] In the present invention, the tempered stabilizer bar is placed in the first positioning groove on the positioning piece, and the stabilizer bar is positioned by multiple positioning pieces, and then the end of the stabilizer bar is positioned by the positioning block. The distance between the blocking piece on the positioning block and the latch is specially designed. Due to the obstruction of the blocking piece, if the end of the stabilizer bar cannot be placed in the second positioning groove on the positioning block, it means that the end of the stabilizer bar is too long and out of tolerance, that is, the stabilizer bar does not meet the requirements; if the end of the stabilizer bar can be placed in the second positioning groove, it means that the end of the stabilizer bar is not out of tolerance, and then the latch is inserted into the pin hole at the end of the stabilizer bar to position the stabilizer bar. The detection tooling can quickly detect whether the end of the stabilizer bar is out of tolerance, and at the same time, it can prevent product failure caused by failure to operate the latch.

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 2As shown, a preferred embodiment of the present invention proposes a detection tool with an out-of-tolerance detection function, which mainly includes a tooling plate 1, a coarseness detection module 5, an out-of-tolerance detection module 6, a first positioning member 2, a second positioning member 3 and a third positioning member 4. The overall shape of the stabilizing bar is similar to a U-shape, and its two ends are similar to a symmetrical structure (actually asymmetrical, with a certain height difference).

[0025] Five first positioning members 2 are provided. Three of these are mounted and fixed in the middle area of the tooling plate 1 to position the straight sections in the middle of the stabilizer bar. The remaining two are mounted and fixed at each end of the tooling plate 1 to position the shorter straight sections at both ends of the stabilizer bar. Second and third positioning members 3 and 4 are mounted at both ends of the tooling plate 1 to position the curved sections at both ends of the stabilizer bar.

[0026] The distribution positions of the first positioning member 2, the second positioning member 3, the third positioning member 4 and the out-of-tolerance detection module 6 are adapted to the shape of the stabilizer bar, wherein two out-of-tolerance detection modules 6 are provided, corresponding to the positions of the two end heads of the stabilizer bar (i.e., the flat structures at both ends of the stabilizer bar).

[0027] A first positioning groove is formed on each of the first positioning member 2 , the second positioning member 3 and the third positioning member 4 . The size of the first positioning groove is adapted to the diameter of the stabilizing bar so as to accurately position the stabilizing bar.

[0028] refer to Figure 1 There are also two thickness detection modules 5, which correspond to the positions of the bushings at both ends of the straight section in the middle of the stabilizer bar. The three first positioning members 2 are located between the two thickness detection modules 5.

[0029] like Figure 3 As shown, the thickness detection module 5 consists of a positioning base 51, a detection plate 52, and a mounting block 53. The mounting block 53 is fixed to one side of the positioning base 51 by bolts. The mounting plate has a sliding groove running through it, and the detection plate 52 is connected to the sliding groove in a horizontal manner. A handle 54 is fixedly welded to the detection plate 52. At the same time, a strip-shaped hole is formed on the top surface of the mounting block 53, which is connected to the sliding groove. The handle 54 can be inserted through the strip hole. A person can manually grasp the handle 54 to drive the detection plate 52 to slide.

[0030] There is a third positioning groove on the positioning base 51, and the depth of the third positioning groove is adapted to the diameter of the portion of the stabilizer bar used for bonding the bushing. After tempering, the stabilizer bar is placed in the positioning piece and positioned by several positioning pieces. The portion of the stabilizer bar used for bonding the bushing will be embedded in the corresponding third positioning groove on the positioning base 51. Then, the detection plate 52 is manually moved by the handle 54. The detection plate 52 can slide along the slide groove to the top of the positioning base 51. If the detection plate 52 can cover the upper opening of the third positioning groove, it means that the thickness of the portion of the stabilizer bar meets the requirements, which facilitates the subsequent bushing to be firmly wrapped around the stabilizer bar. On the contrary, if the upper side of the stabilizer bar exposes the third positioning groove on the positioning base 51, then due to the obstruction of the stabilizer bar, the detection plate 52 cannot slide to the top of the third positioning groove and cover the third positioning groove, which means that the stabilizer bar does not meet the requirements.

[0031] like Figure 4 As shown, the out-of-tolerance detection module 6 consists of a positioning block 61, a latch 62, and a blocking plate 63. The positioning block 61 has a second positioning slot sized to match the flat ends of the stabilizer bar. The latch 62 is inserted into the positioning block 61 perpendicular to the second positioning slot. The blocking plate 63 is bolted to the side of the positioning block 61 near the stabilizer bar. The original second positioning slot was continuous from front to back, but the presence of the blocking plate 63 has changed the slot from being continuous at one end to being closed at the other.

[0032] The stabilizer bar has flat ends, each with a pinhole for the latch 62. The distance between the blocking plate 63 and the latch 62 is specifically designed to be no greater than the distance between the end and the pinhole on a standard stabilizer bar (i.e., a qualified product). If the end of the stabilizer bar is out of tolerance, the blocking plate 63 will prevent the stabilizer bar from fully fitting into the second positioning slot on the positioning block 61.

[0033] In actual operation, when a worker places the stabilizer bar on the inspection tool, if the stabilizer bar is out of tolerance (i.e., the end length of the stabilizer bar exceeds the standard length), the stabilizer bar cannot be inserted into the second positioning groove on the positioning block 61, and the stabilizer bar is detected as non-compliant. If the stabilizer bar is not out of tolerance, the pin 62 is then inserted into the pin hole at the end of the stabilizer bar to position the stabilizer bar so that the thickness of the area on the stabilizer bar where the bushing is bonded can be tested using the thickness inspection module 5.

[0034] In this embodiment, the blocking plate 63 is detachable. Figure 5In other embodiments, a blocking portion 64 can be formed by extending vertically upward at one end of the second positioning groove on the positioning block 61, so that one end of the second positioning groove is not through, and the function is consistent with that of the above-mentioned blocking plate 63. The blocking portion 64 is integrated with the positioning block 61, so it has higher strength.

[0035] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
