[0044] In order to make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0045] As shown in Figures 1-3 The utility model provides a tilt angle sensor debugging commutation device for realizing the debugging detection process of the tilt angle sensor product to be measured, especially the double-shaft tilt angle sensor product which needs to be commutated, the device is installed on a single-shaft high-precision turntable 100, the single-shaft high-precision turntable 100 is automatically controlled by an upper computer, and specifically comprises:

[0048] The structure and working principle of each component of the device will be introduced below.

[0049] As shown in Figure 4 In the double-shaft commutation assembly, a rotating shaft hole is formed in the middle of the horizontal mounting plate 202, and upper and lower bearing mounting holes for mounting bearings are formed around the rotating shaft hole on the upper and lower surfaces of the horizontal mounting plate 202 (the hole diameter of the upper and lower bearing mounting holes is larger than that of the rotating shaft hole), the lower part of the upper bearing 2071 is embedded in the upper bearing mounting hole, and the upper part is embedded in the stepped hole of the upper bearing pressing block 2041, so that the upper bearing 2071 is limited in the space formed by the upper bearing mounting hole and the stepped hole of the upper bearing pressing block 2041; the upper part of the lower bearing 2072 is embedded in the lower bearing mounting hole, and the lower part is embedded in the stepped hole of the lower bearing pressing block 2042, so that the lower bearing 2072 is limited in the space formed by the lower bearing mounting hole and the stepped hole of the lower bearing pressing block 2042.

The lower bearing retainer 2062 is arranged between the toothed flange bolt 208 and the lower bearing 2072, so as to avoid direct contact with the lower bearing 2072 during locking of the toothed flange bolt 208, thereby avoiding damage to the lower bearing 2072.

[0052] As shown in Figure 1 and 2 The horizontal mounting plate 202 is fixed to the horizontal mounting base plate 201 by pins and screws, and two supporting blocks 203 are arranged between the horizontal mounting plate 202 and the horizontal mounting base plate 201, so as to ensure that the horizontal mounting plate 202 is vertically arranged with the horizontal mounting base plate 201, and to disperse the radial force acting on the fixing screws between the horizontal mounting plate 202 and the horizontal mounting base plate 201, thereby reducing the sagging of the horizontal mounting plate 202 due to gravity, ensuring the levelness of the horizontal mounting plate 202, and fixing one side of the horizontal mounting base plate 201 to the single-axis high-precision rotary table, so that the whole double-axis reversing assembly rotates with the single-axis high-precision rotary table 100.

[0053] The lower surface of the horizontal mounting plate 202 is provided with three 24PIN quick connection terminals 214 for communication with the upper computer, and the lower surface of the mounting disc 209 is provided with eight 8PIN quick connection terminals 213, one end of which is connected to the 24PIN quick connection terminal 214, and the other end is connected to the product to be tested 306 through a wire with a connector.

[0055] The utility model can satisfy the debugging working condition of different rotating directions, for the working condition needing clockwise reversing, corresponding limiting block 211 and indexing plunger pin 212 need to be installed on the second installation position B and the third installation position C on the upper surface of the mounting disc 209, and corresponding limiting block 211 needs to be installed at the 0° and -90° positions on the lower surface, for the working condition needing counterclockwise reversing, corresponding limiting block 211 and indexing plunger pin 212 need to be installed on the first installation position A and the fourth installation position D on the upper surface of the mounting disc 209, and corresponding limiting block 211 needs to be installed at the 0° and +90° positions on the lower surface, it needs to be noted that clockwise reversing and counterclockwise reversing cannot exist simultaneously, otherwise the mounting disc 209 cannot rotate.

[0056] In order to cooperate with the indexing plunger pin 212 and the limiting block 211, the mounting disc 209 can be accurately positioned at the +90° position or the -90° position during clockwise or counterclockwise reversing operation, the utility model discloses that the installation positioning hole of the limiting block 210 is arranged at the 0° position on the upper surface of the horizontal mounting plate 202, and the limiting block 210 is fixed at the 0° position on the upper surface of the horizontal mounting plate 202 through a pin and a screw.

[0057] As Figure 6a And 6bAs shown, the limit block 210 includes a block base, and a positioning part and a groove part provided on the block base, two asymmetric grooves (a first trapezoidal groove a and a second trapezoidal groove b) are arranged in the groove part, in this example, the length of the first trapezoidal groove a is 14mm, and the length of the second trapezoidal groove b is 10mm, which can be adjusted according to specific use requirements in actual use, the first trapezoidal groove a and the second trapezoidal groove b are arranged at the upper left position of the block base, the positioning part is arranged at the lower right position of the block base, and the center mounting hole is arranged at the center of the limit block 210, the cross sections of the first trapezoidal groove a and the second trapezoidal groove b are both right-angled trapezoids with the same slope (the slope value range is 60°-70°, and in this example, it is 60°), but the right-angled edges of the two are oppositely arranged, the positioning part and the corresponding limit block 211 are matched to realize the positioning of 0° or ±90° position in the rotating process of the installation disc 209, such as Figure 6c and 6d As shown, the first trapezoidal groove a and the second trapezoidal groove b are matched with the corresponding indexing plunger pin 212 to realize the position locking after the installation disc 209 is rotated to 0° or ±90° position and the production reverse pressing force.

[0058] In this example, the first trapezoidal groove a is closer to the center mounting hole of the limit block 210 than the second trapezoidal groove b, and the inner side surface of the groove part of the limit block 210 close to the center line is provided as a first positioning surface c, and the inner side surface of the positioning part close to the center line is provided as a second positioning surface d.

[0059] The working principle of the utility model is as follows:

[0060] 1, clockwise rotation of the reversing working condition

[0061] As shown in Figure 7 and Figure 8 facing the rotary table 100, if the installation disc 209 needs to be clockwise rotated for reversing, the first limit block 2111 is installed at the 0° position of the lower surface of the installation disc 209, the second limit block 2112 is installed at the-90° position, and the first indexing plunger pin 2121 and the second indexing plunger pin 2122 are correspondingly installed on the installation positioning holes at the second installation position B and the third installation position C;

[0062] When the mounting disc 209 is at the 0° position, the limiting surface of the first limiting block 2111 located at the second mounting position B contacts the second positioning surface d of the limiting stop 210, thereby restricting the counterclockwise rotation of the mounting disc 209. At this time, the first indexing plunger pin 2121 is pushed down, and its cylindrical end contacts the inclined surface of the first trapezoidal groove a on the limiting stop 210. Due to the existence of the inclined surface, as the cylindrical end of the first indexing plunger pin 2121 continues to slide downward, the force exerted by the inclined surface on the cylindrical end of the first indexing plunger pin 2121 will... A horizontal component force is generated, which will push the mounting disk 209 to rotate counterclockwise. However, since the first limit block 2111 has already contacted the second positioning surface d of the limit stop 210, the mounting disk 209 cannot continue to rotate counterclockwise. At this time, the function of this horizontal component force is to keep the first limit block 2111 in close contact with the second positioning surface d of the limit stop 210. During the entire process of the reversing assembly rotating with the single-axis high-precision turntable 100, the mounting disk 209 can always maintain the 0° position.

[0063] When the mounting disc 209 needs to be rotated 90° clockwise from the 0° position, first pull up the first indexing plunger pin 2121 at the second mounting position B vertically and rotate it 90° to release the lock. At this time, the mounting disc 209 can rotate clockwise. Figure 9 As shown, after the mounting disc 209 rotates clockwise from the 0° position to the +90° position, the second limiting block 2112 located at the -90° position on the mounting disc 209 contacts the first positioning surface c of the limiting stop 210, thereby restricting the mounting disc 209 from continuing to rotate clockwise. At this time, the second indexing plunger pin 2122 located at the -90° position on the mounting disc 209 is pushed down, and its cylindrical end contacts the inclined surface of the second trapezoidal groove b on the limiting stop 210. Due to the existence of the inclined surface, as the cylindrical end of the second indexing plunger pin 2122 continues to slide downward, the inclined surface... The force at the cylindrical end of the second indexing plunger pin 2122 will generate a horizontal component force, which will push the mounting disc 209 to rotate clockwise. However, since the second limit block 2112 has already contacted the first positioning surface c of the limit stop 210, the mounting disc 209 cannot continue to rotate clockwise. At this time, the function of this horizontal component force is to keep the second limit block 2112 in close contact with the first positioning surface c of the limit stop 210. During the entire process of the reversing assembly rotating with the single-axis high-precision turntable 100, the mounting disc 209 can always remain at the +90° position.

[0064] 2. Counterclockwise rotation reversing condition

[0065] Similar to the clockwise rotation reversing condition, such as Figure 10 and Figure 11As shown, facing the rotary table 100, if the installation disc 209 needs to be installed for counterclockwise rotation switching, a third limit block 2113 is installed at the 0° position of the lower surface of the installation disc 209, a fourth limit block 2114 is installed at the +90° position, and a third indexing plunger pin 2123 and a fourth indexing plunger pin 2124 are correspondingly installed on the installation positioning holes at the first installation position A and the fourth installation position D;

[0066] When the installation disc 209 is at the 0° position, the limiting surface of the third limit block 2113 at the first installation position A is in contact with the first positioning surface c of the limiting block 210, thereby limiting the clockwise rotation of the installation disc 209, at this time the third indexing plunger pin 2123 is pushed down, and the cylindrical end thereof is in contact with the inclined surface of the second trapezoidal groove b on the limiting block 210; due to the existence of the inclined surface, during the continuous downward sliding of the cylindrical end of the third indexing plunger pin 2123, the force of the inclined surface on the cylindrical end of the third indexing plunger pin 2123 generates a horizontal component force, which pushes the installation disc 209 to rotate clockwise, but since the third limit block 2113 has been in contact with the first positioning surface c of the limiting block 210, the installation disc 209 cannot continue to rotate clockwise, at this time the horizontal component force functions to keep the third limit block 2113 in close contact with the first positioning surface c of the limiting block 210, and during the rotation of the switching assembly following the single-shaft high-precision rotary table 100, the installation disc 209 can always remain at the 0° position unchanged.

[0067] When the installation disc 209 needs to rotate counterclockwise by 90° from the 0° position, the third indexing plunger pin 2123 at the first installation position A is vertically pulled up and rotated by 90° to be unlocked, at this time the installation disc 209 can rotate counterclockwise. Figure 12 As shown, after the installation disc 209 rotates counterclockwise from the 0° position to the -90° position, the fourth limit block 2114 at the +90° position of the installation disc 209 is in contact with the second positioning surface d of the limiting block 210, thereby limiting the continued counterclockwise rotation of the installation disc 209, at this time the fourth indexing plunger pin 2124 at the +90° position of the installation disc 209 is pushed down, and the cylindrical end thereof is in contact with the inclined surface of the first trapezoidal groove a on the limiting block 210; due to the existence of the inclined surface, during the continuous downward sliding of the cylindrical end of the fourth indexing plunger pin 2124, the force of the inclined surface on the cylindrical end of the fourth indexing plunger pin 2124 generates a horizontal component force, which pushes the installation disc 209 to rotate counterclockwise, but since the fourth limit block 2114 has been in contact with the second positioning surface d of the limiting block 210, the installation disc 209 cannot continue to rotate counterclockwise, at this time the horizontal component force functions to keep the fourth limit block 2114 in close contact with the second positioning surface d of the limiting block 210, and during the rotation of the switching assembly following the single-shaft high-precision rotary table 100, the installation disc 209 can always remain at the -90° position unchanged.

[0068] Example 1

[0069] Tilt sensor products with round housing requiring three holes for installation

[0070] like Figure 13 As shown, the mounting disc 209 has eight sets of positioning posts, three in each set, which can be configured according to the height and mounting hole spacing of different products to install the tilt sensor products under test. The positioning posts must ensure the consistency of the orientation of the eight products after installation to facilitate parallel debugging. The mounting disc 209 also has four sets of vertical elbow clamps and corresponding mounting holes for the first elbow clamp pad 301. Two sets of vertical elbow clamps 302 and pads can be installed diagonally, or all four sets of vertical elbow clamps 302 and pads can be installed. In addition to the vertical elbow clamps 302 having a certain height adjustment range, the first elbow clamp pad 301 can be adjusted according to the height of different products under test 306. After the eight products under test 306 are mounted on the positioning posts 303, all the products under test 306 are pressed and fixed by a pressure plate 304 with holes, and then the vertical elbow clamps 302 press the pressure plate 304, thus indirectly and completely pressing the eight products under test 306.

[0071] like Figure 14 As shown, to prevent the area of ​​the pressure plate 304 near the clamping point of the vertical elbow clamp 302 from deforming under stress and becoming concave, and the area of ​​the pressure plate 304 away from the clamping point of the vertical elbow clamp 302 from warping up and not pressing the product 306 under test tightly, in this example, a buffer washer 305, such as EVA sponge, is added at the clamping position corresponding to each product 306 under test on the back of the pressure plate 304. The buffer washer 305 is made relatively thinner at the position closer to the clamping point of the vertical elbow clamp 302, and relatively thicker at the position farther from the clamping point of the vertical elbow clamp 302. This can ensure that all 8 products 306 under test can be pressed tightly, while also preventing the products 306 under test from being damaged.

[0072] Example 2

[0073] Tilt sensor products with non-circular housing

[0074] like Figure 15 As shown, eight product positioning blocks 308 are provided on the mounting disc 209, along with eight sets of vertical elbow clamps 302 and mounting holes for second elbow clamp pads 307. The product positioning blocks 308 are used to position the product under test 306 (a square shell in this example). The vertical elbow clamps 302 are then used to press the product under test 306 firmly. The product positioning blocks 308 must ensure that the orientation of the eight products under test 306 is consistent after installation to facilitate parallel debugging.
