Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, and more specifically, it relates to a testing tooling for automotive aluminum alloy steering gear blanks. Background Technology

[0002] The inspection of automotive aluminum alloy steering gear blanks is a key step in ensuring the quality of the steering system. Strict verification is required for the dimensional accuracy and mounting hole positions of the blanks.

[0003] Traditional testing fixtures have many shortcomings: poor adaptability, making it difficult to meet the testing requirements of different models of steering gear blanks; fixed limiting structure, making it impossible to accurately position the workpiece, resulting in insufficient testing accuracy; integrated design of the fixture structure, which makes it easy for debris to accumulate on the surface after long-term use, making cleaning operations cumbersome; and inconvenient adjustment of testing components, affecting testing efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a testing fixture for automotive aluminum alloy steering gear blanks, which solves the problems of poor adaptability, insufficient testing accuracy, and inconvenient cleaning associated with traditional testing fixtures.

[0005] The purpose and effectiveness of this utility model's inspection fixture for automotive aluminum alloy steering gear blanks are achieved through the following specific technical means: A tooling for inspecting automotive aluminum alloy steering gear blanks includes a tooling base; two support blocks are symmetrically welded to the bottom end face of the tooling base, both support blocks are in contact with the worktable, four plug rods are inserted into the tooling base, the upper ends of the two plug rods on the left are welded to a first base block, the upper ends of the two plug rods on the right are welded to another first base block, a limiting seat slides on each first base block, and a first threaded rod is threadedly connected to each first base block, with the inner ends of the two first threaded rods rotating on the two limiting seats respectively.

[0006] Furthermore, the lower ends of both connector rods are polished, and after polishing, the lower ends of both connector rods are curved.

[0007] Furthermore, the plug rod, the first base block, the limiting seat, and the first threaded rod together form the first limiting part; two sliding seats are symmetrically fixed on the upper end face of the tooling seat, and a second base block slides on each sliding seat. A first locking screw for locking the second base block on the sliding seat is threaded onto each second base block.

[0008] Furthermore, each of the second base blocks is threaded with a second threaded rod, and each second threaded rod has a limiting block rotating at one end of its inner side. The bottom surfaces of the two limiting blocks are in contact with the upper surface of the tooling seat. The two limiting blocks are the front and rear limiting components of the aluminum alloy steering gear.

[0009] Furthermore, the sliding seat, the second base block, the first locking screw, the second threaded rod, and the limiting block together form the second limiting part; an mounting arm slides on one of the rear sliding seats, and a second locking screw for fixing the mounting arm on the sliding seat is threaded onto the mounting arm.

[0010] Furthermore, a guide rod slides on the mounting arm, a detection block is welded to the lower end of the guide rod, and a helical spring is sleeved on the guide rod. The lower end of the helical spring contacts the upper end face of the mounting arm, and the upper end of the helical spring contacts the upper end of the guide rod. The mounting arm, guide rod, detection block, helical spring, and second locking screw together form the detection unit.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In terms of improved adaptability, this application adjusts the spacing of the limiting seats by adjusting the first threaded rod of the first limiting part, and adjusts the position of the second base block by adjusting the sliding seat of the second limiting part and the spacing of the limiting blocks by adjusting the second threaded rod. Combined with the left and right sliding adjustment of the mounting arm of the detection part, it can achieve precise adaptation to different models of aluminum alloy steering gear blanks without the need to change special tooling, thus greatly improving the versatility of the test.

[0012] In terms of ensuring detection accuracy, the first and second limiting parts work together to limit the blank in both directions (left and right, front and back) to prevent workpiece displacement during detection, ensure precise alignment between the detection block and the connecting hole of the blank, and significantly improve the accuracy of the detection data.

[0013] In terms of ease of operation and maintainability, the arc-shaped structure below the plug rod reduces plugging resistance, making the installation of the first base block smoother; the first base block can be disassembled as a whole with the plug rod, making it easy to quickly clean debris from the surface of the tooling seat; the helical spring design of the detection part can automatically reset after pressing the test, simplifying the operation process and comprehensively improving the detection efficiency and tooling maintenance convenience, making it suitable for batch testing scenarios of automotive aluminum alloy steering gear blanks.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a tooling for inspecting automotive aluminum alloy steering gear blanks, including a tooling base 1; two support blocks 101 are symmetrically welded to the bottom end face of the tooling base 1, both support blocks 101 are in contact with the worktable, and four insertion rods 201 are inserted into the tooling base 1. The upper ends of the two insertion rods 201 on the left are welded to a first base block 202, and the upper ends of the two insertion rods 201 on the right are welded to another first base block 202. Each first base block 202 has a sliding... There is a limiting seat 203, and each first base block 202 is threaded with a first threaded rod 204. The inner ends of the two first threaded rods 204 rotate on the two limiting seats 203 respectively. The left and right limits of the aluminum alloy steering gear can be realized through the two limiting seats 203. When cleaning the debris on the tooling seat 1, the two first base blocks 202 can be pulled upwards directly. At this time, the plug rod 201 is disengaged from the tooling seat 1, which makes it convenient to clean the debris on the tooling seat 1.

[0025] The first limiting part 2 is composed of the plug rod 201, the first base block 202, the limiting seat 203 and the first threaded rod 204. The upper end face of the tooling seat 1 is symmetrically fixed with two sliding seats 301. Each sliding seat 301 has a second base block 302 sliding on it. Each second base block 302 is threaded with a first locking screw 303 for locking the second base block 302 on the sliding seat 301. By adjusting the position of the second base block 302 on the sliding seat 301, it can adapt to the limiting of different models of aluminum alloy steering gears.

[0026] Each second base block 302 is threaded with a second threaded rod 304. Each second threaded rod 304 has a limiting block 305 rotating at one end of its inner side. The bottom surfaces of the two limiting blocks 305 are in contact with the upper surface of the tooling seat 1. The two limiting blocks 305 are the front and rear limiting components of the aluminum alloy steering gear. During use, the aluminum alloy steering gear can be limited by the two limiting blocks 305. By limiting the aluminum alloy steering gear, the detection accuracy can be guaranteed.

[0027] The sliding seat 301, the second base block 302, the first locking screw 303, the second threaded rod 304, and the limiting block 305 together form the second limiting part 3; a mounting arm 401 slides on the rear sliding seat 301, and a second locking screw 405 is threadedly connected to the mounting arm 401 for fixing the mounting arm 401 on the sliding seat 301. By adjusting the left and right position of the mounting arm 401, it can adapt to the testing of different models of aluminum alloy steering gears.

[0028] The mounting arm 401 has a guide rod 402 that slides on it. A detection block 403 is welded to the lower end of the guide rod 402. A coil spring 404 is sleeved on the guide rod 402. The lower end of the coil spring 404 contacts the upper surface of the mounting arm 401, and the upper end of the coil spring 404 contacts the upper end of the guide rod 402. The mounting arm 401, guide rod 402, detection block 403, coil spring 404, and second locking screw 405 together form the detection part 4. During the detection, the guide rod 402 is pressed down by hand. At this time, the guide rod 402 and the detection block 403 move downward. The detection is completed by inserting the detection block 403 into the connection hole on the aluminum alloy steering gear.

[0029] Example 2: Based on Example 1, the lower ends of both plug rods 201 are polished. After polishing, the lower ends of both plug rods 201 are arc-shaped. When the plug rods 201 are plugged into the tooling base 1, the plugging is smoother and more convenient under the guidance of the arc-shaped part of the plug rods 201.

[0030] Working principle: Before use, adjust the fixture according to the model and specifications of the aluminum alloy steering gear blank to be tested: Loosen the first locking screw 303, slide the second base block 302 to the appropriate position and then lock it; rotate the second threaded rod 304 to adjust the distance between the two limit blocks 305 to match the front and rear width of the blank; loosen the second locking screw 405, slide the mounting arm 401 to align the testing block 403 with the connecting hole position of the blank and then lock it; place the blank in the designated position of the fixture 1, rotate the two first threaded rods 204 to drive the limit seat 203 to move inward until the limit seat 203 is tightly fitted with the left and right sides of the blank, completing the left and right limit; confirm that the front and rear end faces of the blank are aligned with the two limit blocks 305. Contact is made to achieve bidirectional positioning; press down on the guide rod 402 to move the detection block 403 down. If the detection block 403 can be accurately inserted into the connecting hole of the blank without obvious jamming, the hole position accuracy of the blank is judged to be qualified; if it cannot be inserted or is blocked, it is judged to be unqualified; after the test is completed, release the guide rod 402, reset it under the action of the helical spring 404, rotate the first threaded rod 204 in the opposite direction, release the limit seat 203, and the blank can be taken out; after long-term use, if the surface of the tooling seat 1 is accumulated with debris, pull the first base block 202 upward to make the insertion rod 201 disengage from the tooling seat 1, and the surface of the tooling seat 1 can be thoroughly cleaned. After cleaning, reinsert the insertion rod 201 into the tooling seat 1, and it can be used again.
