Detailed Description

In order to make the objects and features of the present invention more comprehensible, embodiments of the present invention are further described below with reference to the accompanying drawings, however, the present invention may be implemented in various forms, and should not be limited to the described embodiments. Also, the embodiments and features of the embodiments in the present application are allowed to be combined with or substituted for each other without conflict. The advantages and features of the present invention will become more apparent in conjunction with the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Fig. 1 shows a fixed stand as a processing object of the present invention. After the fixed support and the automobile brake pad are fixed, the fixed support is integrally installed on an automobile hub and connected with a brake system, so that the brake pad is controlled. After the brake pad and the fixing support are fixed, a plurality of contact surfaces are arranged between the brake pad and the fixing support, and the brake pad and the fixing support are exposed in the air for a long time and are inevitably contacted with various rainwater and sewage in the use process, so that water stains on the contact surfaces are not easy to dry in the shade, and rusty spots are easy to generate. The rusty spots are one of the hidden troubles for safe driving of the automobile. In order to ensure the braking effect, the contact surfaces need to be oiled to minimize the generation of rusts. Fig. 1 shows a fixing bracket 1 including 8 contact surfaces with a brake pad: contact surface 13, contact surface 14, contact surface 15, and contact surface 16. As can be seen from the illustration, the fixing bracket 1 is symmetrical, so that the other 4 contact surfaces, not shown, are on the opposite side of the

contact surfaces

13, 14, 15 and 16. The 8 contact surfaces are the objects to be sprayed with oil in this embodiment.

Fig. 2 to 4 show a plan view, a front view and a side view of the oil injection tool 2 in the present embodiment, respectively.

As can be seen from the top view of fig. 2, the oil spraying tool 2 is an i-shaped structure disposed on the first bottom plate 21, the middle is a baffle 22, and the two sides are supporting walls. As shown in the front view of fig. 3, the baffle plate 22 is of an inverted-inverted. As shown in fig. 2 and 4, the support wall is also provided with a plurality of oil holes 24. The oil injection holes 24 are externally connected with an oil injection system, and oil bodies for injecting oil to the 8 contact surfaces flow out of the oil injection holes 24. Specifically, each oil injection hole 24 is connected with a hose and a nozzle, and by adjusting the positions of the hose and the nozzle, oil can be uniformly injected to 8 contact surfaces shown in fig. 1, so that rusty spots generated at the contact surfaces can be prevented or reduced. Further, since the area of each contact surface is different, it is more preferable to control the amount of oil sprayed to the different contact surfaces according to the area of the contact surface.

When the fixing bracket 1 is mounted, the abutment surface 11 shown in fig. 1 abuts against the lower half 222 of the baffle plate 22, the portion requiring fuel injection is positioned above the upper half 221 of the baffle plate 22, and the measurement surface 12 faces the thickness detection tool 3 (described later). At this time, the fixing bracket 1 is in an upright state against the baffle plate 22, which is an incompletely stable state.

Fig. 5 and 6 show a top view and a side view of the thickness detection tool 3 in the present embodiment, respectively. As can be seen from fig. 2, the thickness detection tool 3 is a symmetrical structure, which corresponds to the fixing support 1. As shown in the figure, the thickness detection tool 3 includes two displacement detection sensors 33. Since the displacement detecting sensor 33 is a high-precision instrument and is easily damaged by collision, and particularly, the protruding rod of the displacement detecting sensor 33 is easily collided by the fixing bracket 1 or an operator, the front end of the protruding rod is sleeved with the anti-collision mechanism 32. The extension rod of the displacement sensor 33 is fixedly connected to the crash mechanism 32 via a bearing inside the crash mechanism 32. The anti-collision mechanism 32 is cylindrical and wraps the extension bar, so that the extension bar is not easy to skew even if being collided, the internal extension bar is not influenced, and the function of protecting the extension bar is achieved. Further, the top end of the bump guard 32 has a flat surface 321. After the plane 321 extends out, the plane abuts against a mounting hole of the fixed support 1 standing on the oil injection tool 2. The contact surface between the plane 321 and the fixed bracket 1 is far larger than the contact surface between the extension bar of the displacement detection sensor 33 and the fixed bracket 1, so that the contact is stable, and the accuracy of the measured data can be ensured. Furthermore, in this embodiment, a mounting hole is provided for the abutted position, and a truncated cone-shaped protrusion is further provided in the middle of the plane 321, and the protrusion is adapted to the size of the mounting hole to play a positioning role, so that it can be ensured that the thickness of the same position is measured when each fixing support is measured, and the obtained data is more convincing.

As mentioned above, the displacement detecting sensors 33 are high-precision instruments, and if they have errors, the deviation of the acquired data is relatively large, which affects the precision of the acquired data, therefore, a dial indicator 35 is disposed behind each displacement detecting sensor 33, and when the relative position between the displacement detecting sensor 33 and the fixed bracket 1 changes, the dial indicator can be recalibrated or calibrated to ensure that the abutting surface 11 shown in fig. 1 is always used as the origin (starting plane) of the measured thickness.

Further, in order to adapt to different types of fixing brackets, two first air cylinders 34 are further provided in the embodiment, and are respectively used for adjusting the positions of the displacement detection sensors 33. That is, the displacement detecting sensor 33 as a whole can be adjusted left and right by the pushing of the first cylinder 34, so that the plane 321 can be accurately aligned with the measuring point.

Referring to fig. 5 and 6 in combination, as mentioned above, the state of the fixing support 1 leaning on the baffle 22 is not completely stable, but when measuring the thickness, the stability of the fixing support 1 needs to be ensured, otherwise the reliability and stability of the measured data are not high. For this reason, in this embodiment, a stabilizing structure is also provided. The stabilizing structure includes a stabilizer bar 37 and a second cylinder 36 associated therewith. The stabilizer 37 is disposed below the displacement sensor 33, and the central axes thereof are parallel to each other. The stabilizer bar 37 is pushed by the second cylinder 36 to extend and contract in the same direction as the displacement detection sensor 33. And the telescopic range of the stabilizer bar 37 is equal to or greater than that of the displacement detection sensor 33 to ensure that the stabilizer bar 37 is reliably abutted on the fixing bracket 1 when the displacement detection sensor 33 is abutted on the fixing bracket 1 to be measured. The effect of propping against the fixed support 1 is that the fixed support 1 is in full and tight contact with the baffle 22 on the oil injection tool 2, because in the thickness measurement system, the contact surface 11 of the fixed support 1 and the baffle 22 is the calculation origin of the thickness. Further, the stabilizer bar 37 is protruded forward at a speed slightly higher than that of the displacement detection sensor 33. During measurement, the stabilizer bar 37 is first abutted to the surface of the fixing bracket 1, so as to provide a stable measurement environment for the displacement detection sensor 33. When the displacement detection sensor 33 is abutted to the mounting hole of the fixing bracket 1, under the clamping of the baffle 22, the stabilizer bar 37 and the displacement detection sensor 33, the stress on both sides of the fixing bracket 1 is uniform, and the displacement detection sensor 33 can measure more accurate and accurate thickness data.

Furthermore, in order to facilitate the adjustment of the placement position during the installation of the thickness detection tool 3 and increase the adjustable range of the whole thickness detection tool 3, the anti-collision structure 32, the displacement detection sensor 33, the first cylinder 34, the dial indicator 35, the second cylinder 36 and the stabilizer bar 37 are all disposed on a bottom plate, the bottom plate is mounted on two slide rails 31 shown in fig. 5, and the bottom plate can easily move on the slide rails 31, so as to adjust the placement position of the whole thickness detection tool 3. After the placement position of the thickness detection tool 3 is adjusted, the thickness detection tool 3 is clamped from both sides of the thickness detection tool 3 by a pair of fixing clamps (not shown) so as not to slide along the slide rail 31, thereby realizing fixation.

Fig. 7 is a plan view showing the combination of the oil spraying tool 2 and the thickness detection tool 3. The fixing bracket 1 is placed between two tools and clamped by the baffle 22, the stabilizer bar 37 and the displacement detection sensor 33, so that the fixing bracket is kept stable. The two processes of oil injection and thickness detection can be carried out simultaneously.

The thickness detection and oil injection tool combines two processes of oil injection and thickness detection in one station, adopts automatic control, can inject oil and measure thickness simultaneously, saves labor and improves production efficiency.

It will be apparent to those skilled in the art that various changes and modifications may be made to the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
