[0034] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0035] Figure 1 The structural schematic diagram of a three - coordinate elastic pressing head device according to an embodiment of the present invention is shown. Figure 2 Shown is the present invention Figure 1 of the sectional view. Please refer to Figure 1 and 2 , in this embodiment, a three - coordinate elastic pressing head device is disclosed, including:

[0036] Fixed cylinder 1, a receiving hole is provided at the top of the fixed cylinder 1;

[0037] Adjusting part 2, part of the adjusting part 2 is received in the receiving hole, and the adjusting part 2 is movably connected to the receiving hole; here, the movable connection means that the adjusting part 2 can move up and down and rotate relative to the receiving hole; preferably, the outer diameter of the adjusting part 2 matches the aperture of the receiving hole, so that the adjusting part 2 will not sway left and right relative to the receiving hole during adjustment.

[0038] Connecting sleeve 3, the connecting sleeve 3 is provided at the top of the adjusting part 2, one end of the adjusting part 2 extends into the interior of the connecting sleeve 3, and is movably connected to the connecting sleeve 3; here, the movable connection means that the movable sleeve 3 can move up and down and rotate relative to the adjusting part 2;

[0039] Pressing part 4, one end of the pressing part 4 movably penetrates through the connecting sleeve 3, and the pressing part 4 is perpendicular to the height direction of the connecting sleeve 3, and the other end of the pressing part 4 is pressed against the workpiece to be detected; as Figure 1 shown, in this embodiment, the fixed cylinder 1, the adjusting part 2 and the connecting sleeve 3 are all vertically arranged. Here, the pressing part 4 is perpendicular to the height direction of the connecting sleeve 3, which means that the pressing part 4 is horizontally arranged, so that the horizontal distance between the pressing part 4 and the workpiece to be detected can be adjusted.

[0040] The fixed cylinder 1 and the adjusting part 2, the adjusting part 2 and the connecting sleeve 3, and the connecting sleeve 3 and the pressing part 4 are all fixed by a fixing part 5.

[0041] When the three - coordinate elastic indenter device of this embodiment is working, first fix the device on the three - coordinate gauge, and then adjust the angle and height by rotating the adjustment part 2 or moving the adjustment part 2 up and down. After adjusting the height and angle, position and fix the fixing sleeve 1 and the adjustment part 2 through the fixing part 5. For the convenience of fixing, the fixing part 5 is selected as a screw, and it is fixed by the screw, which is relatively convenient for installation and disassembly. Then horizontally move the pressure - applying part 4 to adjust the horizontal distance between the pressure - applying part 4 and the workpiece to be detected. After adjustment, position it by screws, so as to realize the flexible adjustment of the contact point between the pressure - applying part 4 and the workpiece to be detected, better fix the workpiece to be detected, facilitate the subsequent detection work, and improve the detection efficiency and accuracy.

[0042] Please refer to Figure 2 , the adjustment part 2 in this embodiment may include:

[0043] An adjusting sleeve 21, and part of the adjusting sleeve 21 is received in the receiving hole;

[0044] A connecting rod 22, both ends of the connecting rod 22 penetrate through the adjusting sleeve 21. One end of the connecting rod 22 extends into the interior of the connecting sleeve 3, and the other end extends into the receiving hole. There is a gap between the connecting rod 22 and the adjusting sleeve 21;

[0045] A spring 23, the spring 23 is movably sleeved on the outer side of the connecting rod 22 and partially located in the gap. One end of the spring 23 is fixedly connected to the top of the inner cavity of the adjusting sleeve 21, and the other end is fixedly connected to the other end of the connecting rod 22.

[0046] Due to the different properties of the glass of automotive instrument panels with different signals, different pressures are required when pressing the glass. As Figure 1 and 2 shown, when adjusting the pressure, loosen all of the fixing part 5, and then press down the connecting sleeve 3 so that the bottom of the connecting rod 22 contacts the bottom of the inner cavity of the fixing cylinder 1. When continuing to press down, the spring 23 will be compressed. Since there are scales 24 indicating different pressures on the outer side of the adjusting sleeve 21, that is, different depths of the adjusting sleeve 21 entering the fixing cylinder 1 result in different pressures, and the deeper the depth, the greater the pressure. If a certain pressure is required, only need to compress the adjusting sleeve 21 to the specified scale. After adjustment, fix the connecting sleeve 3 and the connecting rod 22 through the fixing part 5, and then adjust the height, angle and distance. Preferably, the connecting rod 22 is an I - shaped rod. In this way, on the one hand, it is convenient for the installation of the spring 23, and on the other hand, the connecting rod 22 can be restricted by the fixing part 5 to prevent the connecting rod 22 from detaching from the connecting sleeve 3.

[0047] The fixing cylinder 1, the adjusting sleeve 21, the connecting sleeve 3 and the connecting rod 22 are coaxial, and there will be no deflection during adjustment, which is more applicable.

[0048] Please refer to Figure 2 , the blank holding part 4 may include:

[0049] A blank holding rod 41, the blank holding rod 41 is perpendicular to the connecting sleeve 3;

[0050] A blank holding head 42, the blank holding head 42 is arranged at one end of the blank holding rod 41 away from the connecting sleeve 3, and the contact surface with the workpiece to be detected faces downward. The horizontal distance between the blank holding head 42 and the glass is adjusted through the blank holding rod 41 to find the optimal contact point and position the glass. Preferably, the blank holding rod 41 is an L-shaped rod, and the blank holding head 42 is arranged at the relatively shorter end of the L-shaped rod, and the shorter end faces vertically downward (as Figure 2 shown). A rubber head 43 is sleeved outside the blank holding head 42. When the rubber head 43 contacts the glass, it is a soft contact without hard contact, so it will not cause scratches on the glass surface and ensure the integrity of the glass. The rubber head 43 can be processed by a rubber coating process, and the rubber used can be a soft rubber.

[0051] Through the above technical solutions, the present invention provides a three-coordinate elastic blank holding head device. This device adjusts the distance, height and angle between the blank holding head and the workpiece to be detected through the mutual cooperation between the adjusting part, the connecting sleeve and the blank holding part, so as to adjust the contact point to ensure better fixing and measuring of the glass and improve the measuring efficiency.
