[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] like Figure 1-5 As shown, a vehicle control arm inspection tool includes a base 101, a detection block 102 and three fixed claws. The detection block 102 is arranged on the base 101, and a detection groove 1021 is provided on the detection block 102. The fixed claws are arranged on the side wall of the detection groove 1021. A plurality of detection rods and positioning blocks are arranged in the detection groove 1021; the three fixed claws are respectively arranged at both ends and the middle of the detection groove 1021, and the side wall of the positioning block is provided with rounded corners; the control arm is placed in the detection groove 1021 for inspection, and the overall size of the control arm is inspected by using the shape of the detection groove 1021. The detection rod detects the position of the small hole on the control arm. The three fixed claws fix the control arm from different directions and cooperate with the positioning block to fix the control arm in a specified position, so that the control arm is placed in the detection groove 1021 at the specified position, thereby ensuring the inspection accuracy of the control arm; the rounded corner design on the positioning block prevents the positioning block from causing wear on the side wall of the control arm, making the inspection of the control arm more reliable.

[0033] There is a gap between the inner wall of the detection groove 1021 and the side wall of the control arm. A first connecting block 103 is provided on the base 101. A go / no-go gauge is provided on the first connecting block 103. The go / no-go gauge includes a hand-held part 1041, a first detection wire 1042 and a second detection wire 1043. The first detection wire 1042 and the second detection wire 1043 are respectively provided at both ends of the hand-held part 1041. The cross-sectional diameter of the first detection wire 1042 is larger than the cross-sectional diameter of the second detection wire 1043. A card slot corresponding to the hand-held part 1041 is provided on the first connecting block 103.

[0034] A second connecting block 105 is also provided on the base 101, and a through-hole detector 106 is provided on the second connecting block 105. The through-hole detector 106 includes a detection disk and a central axis rod. The central axis rod runs through the detection disk, and a connecting groove corresponding to the central axis rod is provided on the second connecting block 105. The central axis rod is inserted into the connecting groove to fix the through-hole detector 106.

[0035] After the control arm is placed in the detection groove 1021, the distance between the control arm and the inner wall of the detection groove 1021 and the diameter of the through hole on the control arm are detected using a go / no-go gauge and a through hole detector 106 to ensure that the size of the control arm is within the specified range.

[0036] A mounting hole is provided on the base 101 , a mounting rod 108 is passed through the mounting hole, and a friction pad 109 is provided at the bottom of the mounting rod 108 , and the friction pad 109 is made of rubber.

[0037] A first thread is provided on the side wall of the mounting rod 108, a second thread is provided on the inner wall of the mounting hole, and a plurality of push plates 110 are provided on the mounting rod 108. The plurality of push plates 110 are evenly arranged along the side wall of the mounting rod 108 to push the mounting rod 108 to rotate.

[0038] By rotating the mounting rod 108 so that the first thread and the second thread are matched, the distance between the friction pad 109 and the base 101 is adjusted, so that the inspection fixture can adapt to a variety of different tabletops. The inspection fixture is adjusted to a horizontal state to improve the inspection accuracy of the control arm.

[0039] A groove is provided at the bottom of the friction pad 109 , and a movable cavity is provided at the top of the groove. A piston 111 is provided in the movable cavity. The side wall of the piston 111 fits against the inner wall of the movable cavity and can move along the inner wall of the movable cavity.

[0040] A through cavity communicating with the movable cavity is provided on the mounting rod 108, and a connecting rod 112 is provided on the piston 111; a cavity is provided on the top of the through cavity, and a connecting disk 113 is rotatably connected to the top of the connecting rod 112, and a pull rod 115 and a reset spring 116 are provided on the connecting disk 113, the reset spring 116 rests on the top surface of the cavity, and the pull rod 115 passes through the cavity, a first protrusion 117 is provided on the side wall of the connecting disk 113, and a second protrusion 1131 is provided on the inner wall of the cavity.

[0041] A connecting column 114 is provided on the connecting disk 113, and a movable groove is provided on the connecting column 114. One end of the pull rod 115 is inserted into the movable groove. A slider 1151 is provided on the pull rod 115, and a sliding groove for the slider 1151 to move is provided on the inner wall of the movable groove. The slider 1151 can move in the sliding groove but cannot escape from the sliding groove; a baffle 107 is rotatably connected to the base 101, and the baffle 107 is above the mounting rod 108.

[0042] After the friction pad 109 is placed on the table, the friction pad 109 is pressed down to deform the friction pad 109, and the groove is adsorbed on the table. The baffle 107 is pushed open so that the baffle 107 and the mounting rod 108 are misaligned. The pull rod 115 is pulled upward, and the pull rod 115 drives the connecting plate 113 to move. The piston 111 moves upward to suck the air in the groove, thereby improving the adsorption effect of the friction pad 109. After the first protrusion 117 moves to the top of the second protrusion 1131, the connecting plate 113 is rotated so that the first protrusion 117 is 17 is aligned with the second protrusion 1131, and the second protrusion 1131 is against the first protrusion 117 so that the piston 111 is in a raised state, fixing the inspection tool on the desktop to prevent the inspection tool from moving when in use; the setting of the movable groove allows the pull rod 115 to enter the movable groove after being pulled out, preventing the pull rod 115 from protruding from the top of the mounting rod 108 and causing accidental touch; the baffle 107 blocks the pull rod 115, further reducing the accidental touch of the pull rod 115 and ensuring the stability of the inspection tool.

[0043] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the utility model disclosed herein is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned utility model concept.
