Description

[Technical field]

[0001] The utility model relates to the technical field of tie rod thread detection equipment, in particular to a semi-automatic detection device for automobile steering tie rod thread. [Background technology]

[0002] The specifications and models of automobile steering rods are relatively diverse. They are generally used in the automobile field and are one of the automobile safety parts. They directly affect the stability of automobile handling, the safety of operation and the service life of tires. The existing automobile steering rods, such as the patent announcement number CN109229205A, disclose an automobile steering rod, in which the external thread is mainly connected with the internal thread on the rod body to achieve the fixation of the two. However, if the external thread on the second end of the steering rod is eccentric, it will cause it to be unable to smoothly enter the automobile steering rod. In order to reduce the problem of the connection between the automobile rod and the second end, it will be used A semi-automatic thread detection device is used to detect the thread. The existing automobile steering rod external thread detection device is mainly composed of a fixed rotating mechanism, a connecting plate and a micrometer connection. By adjusting the position of the micrometer in advance and placing the connecting plate against the external thread, the second end is clamped by the fixed rotating mechanism, and the second end is rotated so that the second end is linked to drive the thread to rotate during the rotation process. Once the external thread rotates, the external thread will push the connecting plate to move. When the connecting plate is moving, the connecting plate will contact the probe of the micrometer, so that it pushes the probe to move, thereby achieving the detection of the external thread by the micrometer;

[0003] Although the detection device in the above scheme can detect external threads, the second end of the automobile steering rod is only a straight rod. Instead, its shape needs to be changed according to the application scenario of the automobile. Therefore, its shape is also diverse. However, in the above scheme, only the second end of the straight line can be detected. If the second ends of different shapes are detected, it is easy to cause different shapes, resulting in coaxial offset of the second end during rotation. Once this happens, it will affect the accuracy of external thread detection, resulting in a decrease in the accuracy of its detection. [Contents of the utility model]

[0004] The utility model aims to solve the problems in the prior art and provides a semi-automatic detection device for automobile steering tie rod threads, which can detect the external threads of the tie rod.

[0005] To achieve the above-mentioned purpose, the utility model proposes a semi-automatic detection device for automobile steering rod threads, comprising: a base, a micrometer and a rod fixing mechanism arranged on the base,

[0027] As Figures 1 to 3 , the semi-automatic detection device for the thread of the automotive steering tie rod of the present utility model includes: a base 1, a micrometer 2, and a tie rod fixing mechanism 3 provided on the base 1. Among them, the tie rod fixing mechanism 3 in the present utility model is mainly used to fix the tie rod, and the tie rod fixing mechanism 3 is mainly an electric three-jaw chuck 19. The tie rod can be fixed by the electric three-jaw chuck 19.

[0028] The detection device of the present utility model further includes: a moving seat 4, a turntable 5, a lifting seat 6, and a detection plate 7;

[0029] Among them, the moving seat 4 is driven to be longitudinally or horizontally slidably connected to the base 1, and is mainly used to adjust the position of the detection plate 7;

[0030] The turntable 5 is driven to be rotatably connected to the moving seat 4, and is mainly used to drive the detection plate 7 to rotate. It is worth mentioning that the turntable 5 is mainly started by a first motor 17. The first motor 17 is fixedly connected to the moving seat 4, and the output shaft is fixedly connected to the turntable 5, so as to drive the rotation of the turntable 5;

[0031] When adjusting the position, since the lifting seat 6 is vertically connected to the turntable 5, it is mainly used to adjust the position of the detection plate 7. The lifting seat 6 is mainly driven by an electric push rod three 18. The electric push rod three 18 is fixedly connected to the moving seat 4, and the output shaft is fixedly connected to the lifting seat 6, so as to realize the lifting of the lifting seat 6;

[0032] Due to the detection plate 7, the detection plate 7 is elastically and slidably connected to the lifting seat 6. Among them, the dial indicator 2 is fixedly connected to the lifting seat 6, and one end of the lifting seat 6 is fixedly connected to the top surface of the detection plate 7. The detection plate 7 can be arranged opposite to the pull rod. Therefore, when the detection plate 7 contacts the external thread of the pull rod, by rotating the turntable 5, the detection plate 7 is driven to rotate. During the rotation of the detection plate 7, the external thread will push the detection plate 7 to move, thereby realizing the detection of whether the external thread is eccentric by the dial indicator 2.

[0033] Specifically, since a spring telescopic rod 8 is fixedly connected to the lifting seat 6, one end of the spring telescopic rod 8 far from the lifting seat 6 is fixedly connected to a connecting block 9, and the connecting block 9 is detachably and fixedly connected to the detection plate 7. The spring telescopic rod 8 is located on both sides of the dial indicator 2. Therefore, the spring telescopic rod 8 can reset the detection plate 7, further improving the reset effect of the detection plate 7. It is worth mentioning that by detachably and fixedly connecting the connecting block 9 to the detection plate 7, it is convenient for personnel to replace the detection plate 7.

[0034] Specifically, a protection block 10 is fixedly connected to the measuring needle in the dial indicator 2. By the protection block 10 being in contact with the detection plate 7, the measuring needle of the dial indicator 2 can be protected.

[0035] Specifically, since the moving seat 4 includes a connecting seat one 11 and a connecting seat two 12, the connecting seat one 11 is horizontally slidably connected to the base 1. An electric push rod one 13 is fixedly connected to the base 1, and the output shaft of the electric push rod one 13 is fixedly connected to the connecting seat one 11. The connecting seat two 12 is longitudinally driven and slidably connected to the connecting seat one 11. Therefore, the electric push rod one 13 can push the connecting seat to move, thereby realizing the adjustment of the connecting seat to drive the moving seat 4 to the required position.

[0036] Specifically, since an electric push rod two 14 is fixedly connected to the connecting seat one 11, and the output shaft of the electric push rod two 14 is fixedly connected to the connecting seat two 12, it is convenient for personnel to horizontally adjust the connecting seat two 12.

[0037] Specifically, a bolt is rotatably connected to the connecting block 9. One end of the screw 15 is threadedly connected to the detection plate 7, which is convenient for personnel to replace the detection plate 7.

[0038] Specifically, an inlet 16 for the pull rod to enter is opened on the turntable 5 to prevent the pull rod from abutting against the turntable 5.

[0039] Principle of the utility model: By moving the longitudinal and transverse positions of the moving seat 4, the position of the detection plate 7 can be adjusted. Once the position adjustment of the detection plate 7 is completed, the lifting seat 6 is lifted or lowered. By lifting or lowering the lifting seat 6, the detection plate 7 is brought into contact with the external thread. At this time, the turntable 5 rotates. During the rotation of the turntable 5, the detection plate 7 will be driven to rotate circumferentially. When the detection plate 7 rotates circumferentially and the external thread is eccentric, the external thread will push the detection plate 7 to move. The probe of the micrometer abuts against the detection plate 7 and detects the position of the movement of the detection plate 7, so as to detect whether the external thread is eccentrically coaxial.

[0040] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any simple transformation of the present utility model falls within the protection scope of the present utility model.
