Description

[Technical field]

[0001] The utility model relates to the technical field of ball head position detection of a ball head assembly, in particular to a detection fixture for the ball head position of a control arm. [Background technology]

[0002] The automobile control arm ball joint assembly is an important component in the automobile suspension system. It mainly bears the load transmission and steering effect during the driving of the automobile, and plays a key role in the vehicle's handling stability, driving smoothness and safety. For the detection of the automobile control arm ball joint assembly, the ball joint part is generally tested. By detecting the position of the ball joint, it can be detected whether the ball joint has a gap on the ball seat to avoid the production of defective products. For the detection of the ball joint control arm, a control arm ball joint position detection device is generally used. The existing control arm ball joint detection device mainly places the ball joint assembly into a fixing mechanism by a person, fixes the ball joint assembly by using the fixing mechanism, and presses one end of the probe on the micrometer against the surface of the ball joint by a person, clamps the connecting rod on the ball joint by a manipulator, and shakes the ball joint. The swinging force of the ball joint is used to move the probe back and forth. Once the probe moves forward and backward, the person can check the indication of the micrometer to see if there is any fluctuation, thereby achieving the detection of the ball joint position.

[0003] Although the above scheme can be used to detect the position of the ball head, there are still some problems: the ball head assembly is not only tested for one, but multiple tests are required. In the above scheme, after the detection of a single ball head is completed, the ball head needs to be disassembled, and the ball head to be tested is installed in the fixing mechanism for fixation, and the probe is operated to press against the ball head, and the detection can be completed by moving the ball head. After the single detection of the ball head is completed, the ball head to be tested is completely fixed by manual operation when it is installed. When the person manually fixes it, its position is bound to deviate from the original fixed position. If the probe is not adjusted, it will greatly affect the accuracy of the probe's detection of the ball head. [Contents of the utility model]

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] like Figures 1 to 4A detection and inspection tool for the position of a control arm ball head comprises: a base 2 with a support seat 1, a ball head assembly fixing mechanism 3 arranged on the support seat 1, a moving mechanism 4 arranged on the base 2 and arranged opposite to the ball head, and a micrometer 5 arranged on the base 2, wherein the ball head assembly fixing mechanism 3 is mainly composed of a clamping plate 22, a bidirectional lead screw 23 and a motor 3 24, the motor 3 24 is fixedly connected to the base 2, and the output shaft is fixedly connected to the bidirectional lead screw 23 rotatably connected to the base 2, so that the rotation of the bidirectional lead screw 23 can be realized, and once the bidirectional lead screw 23 rotates, the bidirectional lead screw 23 will drive the clamping plate 22 which is threadedly connected to it and relatively slidably connected to the base 2. The holding plate 22 moves, so that the clamping plate 22 clamps the ball head assembly, further improving the clamping effect of the ball head assembly. After the ball head assembly is clamped, the moving mechanism 4 is started. Since the moving mechanism 4 is mainly composed of a lifting seat 25, a sliding seat 10 and a clamping block 27, the lifting seat 25 is driven by a cylinder 1 28 fixedly connected to the base 2, and can be lifted on the base 2, while the sliding seat 10 is driven by a cylinder 29 to slide and connect to the lifting seat 25, and the clamping block 27 is driven by an electric push rod 3 30 fixedly connected to the base 2, so as to clamp the connecting rod on the ball head, and the ball head can be moved by moving the connecting seat left and right;

[0028] The detection fixture in the utility model also includes: a moving seat 6, a rotating disk 7, a connecting plate 8, a pressure sensor 9, a sliding seat 10 and a control member 11;

[0029] When the position of the ball head needs to be detected, the turntable 7 connected to the moving seat 6 is driven by the motor 4 31 to rotate. The rotation of the turntable 7 can drive the connecting plate 8 fixedly connected to the turntable 7 to move, so that the connecting plate 8 drives the pressure sensor 9 fixedly connected to the connecting plate 8 to be arranged relative to the ball head. At this time, the moving seat 6 connected to the base 2 is driven to move, and the movement of the moving seat 6 indirectly drives the pressure sensor 9 fixedly connected to the connecting plate 8 to move, so that the pressure sensor 9 is in contact with the ball head. Once the pressure sensor 9 is in contact with the ball head, the pressure sensor 9 will transmit a signal to the control member 11 fixedly connected to the base 2. , the control member 11 controls the reset of the moving seat 6, and also controls the sliding seat 10 driven and slidably connected to the base 2 to slide, so that the sliding seat 10 drives the micrometer 5 set on the sliding seat 10 to move, thereby realizing that the measuring needle of the micrometer 5 moves to the position where the pressure sensor 9 and the ball head are in contact, and the measuring needle is in contact with the ball head. At this time, the ball head can be driven to move by the moving mechanism 4, and the micrometer 5 measures the position of the ball head moving in the ball seat through the movement of the ball head, thereby achieving the detection of the position of the ball head. It is worth mentioning that the motor four 31 is fixedly connected to the moving seat 6, and the output shaft is fixedly connected to the turntable 7, so that the rotation of the turntable 7 can be realized.

[0030] Specifically, a push plate 12 is slidably connected to the base 2, and the push plate 12 is mainly used to drive an electric push rod 13 fixedly connected to the base 2. By fixing the output shaft of the electric push rod 13 with the push plate 12, the push plate 12 can push the ball head assembly to adjust the position, thereby further improving the effect of adjusting the position of the ball head assembly.

[0031] Specifically, when the push plate 12 of the ball head assembly moves and slides on the support seat 1, the electric push rod 15 fixedly connected to the base 2 is started, and the output shaft of the electric push rod 15 is fixedly connected to the limit plate 14 which is lifted and connected to the base 2. The limit plate 14 and the push plate 12 are arranged relative to each other, so that the push plate 12 can push the ball head assembly to move and contact with the limit plate 14, thereby achieving the positioning of the ball head assembly. Once the positioning of the ball head assembly is completed, the limit plate 14 moves back to the ball seat, thereby achieving the positioning of the ball head assembly.

[0032] Specifically, since the control component 11 includes a control panel 16, the control panel 16 is fixedly connected to the base 2, and is electrically connected to the pressure sensor 9 through the control panel 16, and can control the sliding position of the sliding seat 10 and the moving seat 6, and then the control panel 16 can control the movement of the sliding seat 10 and the moving seat 6.

[0033] Specifically, when the movable seat 6 needs to move, since a lead screw 17 is rotatably connected to the base 2, the lead screw 17 is threadedly connected to the movable seat 6, and a motor 18 is fixedly connected to the base 2, and the output shaft of the motor 18 is fixedly connected to the lead screw 17, and the motor 18 is electrically connected to the control panel 16, the motor 18 is started, and the lead screw 17 is driven to rotate by the motor 18, and the movable seat 6 is driven to move by the lead screw 17, thereby realizing the adjustment of the position of the movable seat 6.

[0034] Specifically, when the position of the sliding seat 10 needs to be adjusted, since the base 2 is rotatably connected with a lead screw 19, the lead screw 19 is threadedly connected to the sliding seat 10, and the base 2 is fixedly connected with a motor 20 whose output shaft is fixedly connected to the lead screw 19, and the motor 20 is electrically connected to the control panel 16, the motor 20 is started, and the lead screw is driven to rotate by the motor 20, and the lead screw 19 drives the sliding seat 10 to move during the rotation, thereby achieving the adjustment of the position of the sliding seat 10.

[0035] Specifically, when the dial gauge 5 needs to be fixed, the dial gauge 5 can be fixed by fixing the fixing bolts 21 threadedly connected to the support base 1 and fixedly connected to the dial gauge 5 .

[0036] The utility model drives the connecting plate 8 to rotate to be arranged opposite to the ball head through the rotation of the turntable 7, and utilizes the movement of the movable seat 6 to indirectly drive the pressure sensor 9 to move to be arranged opposite to the ball head. At this time, the movable seat 6 moves, and the movement of the movable seat 6 can make the pressure sensor 9 and the ball head stick together. Once the ball head and the pressure sensor 9 stick together, the pressure sensor 9 senses the pressure applied by the ball head and transmits a signal to the control member 11. The control member 11 is used to control the movable seat 6 to reset, and the sliding seat 10 moves, so that the sliding seat 10 drives the measuring needle on the micrometer 5 to move to the position where the pressure sensor 9 and the ball head stick together, and utilizes the movement of the moving mechanism 4, so as to achieve the detection of the ball head position by the micrometer 5.

[0037] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
