Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a toothed gasket type cross-bar spacing testing fixture. Background Technology

[0002] The distance between bars can generally be measured using a distance micrometer. Existing measuring tools are mostly designed for gears (parts with a certain thickness), but they are not suitable for gear-shaped gaskets (thickness ≤ 3mm). Distance micrometer probes are mainly divided into ball-head and cylindrical probes. These probes have a small contact point when measuring gear-shaped gaskets and are prone to tilting, affecting the measurement results and leading to large deviations from the actual values.

The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0039] like Figures 1 to 3As shown in the figure, this is an embodiment of the present invention, which provides a toothed gasket type cross-bar spacing detection fixture, including a base 100, a fixed detection component 200 fixedly disposed relative to the base 100, a sliding detection component 300 slidably disposed relative to the base 100, a limiting component 400 and a measuring component 500 that cooperate with the sliding detection component 300, wherein the sliding detection component 300 and the fixed detection component 200 are disposed opposite to each other.

[0040] The fixed detection component 200 includes a fixed block 201 and a first positioning post 202 vertically disposed on the fixed block 201. The sliding detection component 300 includes a sliding block 301 and a second positioning post 302 vertically disposed on the sliding block 301. The first positioning post 202 and the second positioning post 302 cooperate with the toothed grooves of the toothed gasket 600, that is, the first positioning post 202 and the second positioning post 303 can be positioned in the two radially upward toothed grooves on the toothed gasket 600 to measure the span of the toothed gasket 600.

[0041] The limiting component 400 includes a limiting block 401, a limiting member 402 passing through the limiting block 401 and having its end connected to the sliding block 301, and an elastic member 403 disposed between the sliding detection component 300 and the limiting block 401. Preferably, the limiting member 402 is a bolt, the elastic member 403 is a spring, the smooth part of the bolt passes through the limiting block 401 and the threaded part is threadedly connected to the sliding block 301, and the elastic member 403 is sleeved on the smooth part and abuts between the limiting block 401 and the sliding block 301.

[0042] The measuring component 500 is used to detect the horizontal displacement of the sliding block 301. It can be a torsion spring gauge, which is mounted on the base 100 and the measuring end abuts against the sliding block 301.

[0043] To facilitate the installation of the measuring component 500, a through groove 401a is provided on the limiting block 401 for the measuring component 500 to pass through, and an abutment groove 301a is provided on the sliding block 301 to abut against the measuring component 500.

[0044] To improve the stability of the elastic element 403, a first positioning groove 401b that cooperates with the elastic element 403 is provided on the limiting block 401, and a second positioning groove 301b that cooperates with the elastic element 403 is provided on the sliding block 301.

[0045] The first positioning post 202 includes a measuring positioning part 202a and a mounting positioning part 202b arranged vertically. A positioning hole is provided on the fixing block 201 for the mounting positioning part 202b to extend into, and a positioning pin hole is provided on the side of the fixing block 201 for the positioning pin 203 to be inserted. The first positioning post 202 is mounted on the fixing block 201 via the positioning pin 203. The second positioning post 302 has the same structure as the first positioning post 202. A positioning hole and a positioning pin hole are provided on the sliding block 301 to mate with the second positioning post 302. The second positioning post 302 is mounted on the sliding block 301 via the positioning pin 203. By removing the positioning pin 203, the first positioning post 202 and the second positioning post 302 can be disassembled and sent for calibration.

[0046] When the first positioning post 202 or the second positioning post 302 interferes with the root circle of the toothed pad 600, a clearance plane can be provided on the side of the measuring positioning part 202a facing the toothed pad 600.

[0047] In this example, the base 100 includes a base plate 101, a pad assembly stacked on the base plate 101, and a mounting base 104 fixed at one end of the base plate 101. The measuring component 500 is mounted on the mounting base 104. The limiting block 401 and the fixing block 201 are mounted on the base plate 101 by screws. The pad assembly is provided with a limiting groove 105 that cooperates with the limiting block 401, a sliding groove 106 that cooperates with the sliding block 301, and a mounting groove 107 that cooperates with the fixing block 201. The limiting groove 105, the sliding groove 106, and the mounting groove 107 are all through grooves that penetrate the pad assembly. The limiting groove 105 and the sliding groove 106 are connected in a T-shape, that is, the length of the limiting block 401 is greater than the width of the sliding block 300.

[0048] For ease of processing, the pad assembly includes a support plate 102 stacked on a base plate 101 and a positioning plate 103 stacked on the support plate 102 to provide a positioning plane. The support plate 102 and the positioning plate 103 are fixed to the base plate 101 with screws. During measurement, placing the toothed pad 600 part on the positioning plate 103 can prevent the part from tilting, thereby improving measurement accuracy and efficiency.

[0049] The working principle of this utility model is as follows:

[0050] Adjust the limiting member 402 according to the length of the standard part to adjust the distance between the sliding block 301 and the limiting block 401. Place the standard part between the first positioning post 202 and the second positioning post 302. Install the measuring component 500 on the mounting base 104. Fine-tune the position of the measuring component 500 to ensure that the reading of the measuring component 500 is zero, and then lock it in place. Repeat the measurement of the standard part to confirm that the reading of the measuring component 500 is stable. Figure 4As shown, when the toothed shim 600 is placed between the first positioning post 202 and the second positioning post 302, if the pointer is within the range of the dial scale lines, the size is considered to be qualified.

[0051] Calculation of span distance: L=N1+N+2*D, where N is the length of the standard part; N1 is the reading of the measuring component; when the first positioning post and the second positioning post are set to be cylindrical, D is the diameter of the first positioning post / second positioning post; when the first positioning post and the second positioning post are provided with a clearance plane, D is the maximum value of the clearance plane to the circle diameter.

[0052] In summary, this tooling can improve the detection accuracy and efficiency of measuring the span of toothed gaskets.
