[0026] See Figure 1This embodiment discloses an automotive fixture positioning device, including a positioning base 1, a driving mechanism 2, and a positioning mechanism 3. The top of the positioning base 1 is provided with a positioning slot 11, making the top of the positioning base 1 L-shaped. The driving mechanism 2 is provided on the top of the positioning base 1. The positioning mechanism 3 is provided on both vertical slot walls of the positioning slot 11. Driving the driving mechanism 2 causes the positioning mechanism 3 to move towards the center of the positioning slot 11, thereby realizing the positioning and clamping of the corner of the automotive fixture. Moreover, only the driving mechanism 2 needs to be driven to realize the positioning and clamping of the automotive fixture, which is convenient to operate.

[0027] The positioning base 1 is provided with positioning posts 4 at each of its four corners for installation and fixation.

[0028] See Figures 2 to 4 The driving mechanism 2 includes a drive seat 21, a first elastic component 22, a first pedal 23, a first rack 24, a second elastic component 25, a second rack 26, a third elastic component 27, a wedge block 28, and a second pedal 29. The drive seat 21 is inverted L-shaped. The horizontal section of the drive seat 21 is vertically movable at the top of the positioning seat 1 via the first elastic component 22. The vertical section of the drive seat 21 has an inclined surface that abuts against the positioning mechanism 3. The bottom of the horizontal section of the drive seat 21 is connected by a second connecting... The connecting rod 5 connects to the first pedal 23. The first rack 24 is vertically mounted on the vertical section of the drive seat 21 and can move horizontally through the second elastic component 25. The second rack 26 is vertically mounted on the outer wall of the positioning slot 11 and can move horizontally through the third elastic component 27. The first rack 24 meshes with the second rack 26. The wedge block 28 is engaged between the second rack 26 and the vertical section of the drive seat 21. The bottom of the wedge block 28 is connected to the second pedal 29 through the second connecting rod 6.

[0029] Specifically, by pressing the first pedal 23, the drive seat 21 is subjected to a downward force. Under the action of the first elastic component 22, the drive seat 21 has the power to move downward, which in turn causes the first rack 24 to move downward. This causes the second rack 26 to be subjected to the squeezing force of the first rack 24. Under the action of the third elastic component 27, the second rack 26 moves horizontally away from the first rack 24, causing the first rack 24 to disengage from the second rack 26. This allows the first rack 24 to move downward, thereby enabling the drive seat 21 to move downward. This causes the inclined surface on the vertical section of the drive seat 21 that abuts against the positioning mechanism 3 to move downward, thereby pushing the positioning mechanism 3 to move towards the center of the positioning slot 11, achieving positioning and clamping of the corner end of the vehicle inspection fixture. Then, after releasing the first pedal 23, the second rack 26 is no longer subjected to the squeezing force of the first rack 24. Under the action of the third elastic component 27, the second rack 26 returns to its original position and moves towards the first rack 24, engaging with the first rack 24, so that the positioning mechanism 3 is in the positioning and clamping state.

[0030] By stepping on the second pedal 29, the wedge block 28 is moved downwards. Under the action of the second elastic component 25, the first rack 24 is moved away from the second rack 26, causing the first rack 24 to disengage from the second rack 26. Under the elastic force of the first elastic component 22, the drive seat 21 is moved upwards, causing the inclined surface on the vertical section of the drive seat 21 that abuts against the positioning mechanism 3 to move upwards. This causes the positioning mechanism 3 to reset in a direction away from the center of the positioning slot 11, thereby relaxing the positioning mechanism 3.

[0031] The first elastic component 22 includes a positioning rod 221 and a first return spring 222. The top of the groove wall of the positioning slot 11 is provided with a first positioning hole (not shown in the figure). One end of the positioning rod 221 is connected to the bottom of the horizontal section of the drive seat 11, and the other end extends into the first positioning hole and is connected to the bottom of the first positioning hole through the first return spring 222. The first return spring 222 is always in a compressed state. Specifically, the drive seat 11 is moved downward by the positioning rod 221 and the first return spring 222 is compressed.

[0032] The second elastic component 25 includes a sliding rod 251 and a second return spring 252. The sliding rod 251 passes through the vertical section of the drive seat 21 and is vertically connected to the first rack 24. The second return spring 252, which is always in a compressed state, is sleeved on the sliding rod 251 between the vertical section of the drive seat 21 and the first rack 24. Specifically, by stepping on the second pedal 29, the wedge block 28 is moved down. Under the action of the second return spring 252, the first rack 24 moves away from the second rack 26, causing the first rack 24 to disengage from the second rack 26.

[0033] The third elastic component 27 includes a sliding screw 271 and a third return spring 272. A second positioning hole (not shown in the figure) is formed on the outer wall of the positioning slot 11. One end of the sliding screw 271 is connected to the second rack 26, and the other end extends into the second positioning hole and is connected to the bottom of the second positioning hole through the third return spring 272, which is always in a compressed state. Specifically, when the second rack 26 is subjected to the squeezing force of the first rack 24, the third return spring 272 causes the second rack 26 to move away from the first rack 24, thus disengaging the first rack 24 from the second rack 26.

[0034] See Figure 2 The positioning mechanism 3 includes a positioning plate 31, a push rod 32, and a fourth return spring 33. The positioning plate 31 is disposed near the inner wall of the positioning slot 11. One end of the push rod 32 is connected to the positioning plate 31, and the other end passes through the slot wall of the positioning slot 11 and abuts against the inclined surface of the vertical section of the drive seat 21. The fourth return spring 33, which is always in a compressed state, is sleeved on the push rod 32. One end of the fourth return spring 33 is connected to the end of the push rod 32 near the drive seat 21, and the other end is connected to the positioning slot. Specifically, on the slot wall of the opening 11, the downward movement of the drive seat 21 causes the inclined surface on the vertical section of the drive seat 21 to move downward, thereby pushing the push rod 32 to move towards the center of the positioning slot 11, and thus achieving positioning and clamping of the corner end of the vehicle inspection tool through the positioning plate 31; when the drive seat 21 moves upward, the inclined surface on the vertical section of the drive seat 21 moves upward, causing the push rod 32 to disengage from the inclined surface, and under the action of the fourth return spring 33, the push rod 32 is driven to retract, so that the positioning plate 31 is automatically retracted, realizing the relaxation of the positioning mechanism 3.

[0035] Furthermore, the end of the push rod 32 away from the positioning plate 31 is hemispherical.

[0036] The working principle of this embodiment is as follows: When the first pedal 23 is pressed, the drive seat 21 is subjected to a downward force, and the drive seat 21 has the power to move downward, so that the second rack 26 is subjected to the squeezing force of the first rack 24. Under the action of the second return spring 252, the first rack 24 moves away from the second rack 26, so that the first rack 24 disengages from the second rack 26, thereby allowing the first rack 24 to move downward, thereby realizing the downward movement of the drive seat 21. This causes the inclined surface on the vertical section of the drive seat 21 to move downward, thereby pushing the push rod 32 to move towards the center of the positioning slot 11, and thus achieving the positioning and clamping of the corner end of the car inspection tool through the positioning plate 31. Then, after releasing the first pedal 23, the second rack 26 is no longer subjected to the squeezing force of the first rack 24. Under the action of the third return spring 272, the sliding screw 271 moves towards the first rack 24, thereby causing the second rack 26 to move towards the first rack 24 and mesh with the first rack 24, so that the positioning mechanism 3 is in the positioning and clamping state.

[0037] By stepping on the second pedal 29, the wedge block 28 is moved downward. Under the action of the second return spring 252, the first rack 24 moves away from the second rack 26, causing the first rack 24 to disengage from the second rack 26. Then, under the elastic force of the first return spring 222, the drive seat 21 is moved upward, causing the inclined surface on the vertical section of the drive seat 21 that abuts against the push rod 32 to move upward, causing the push rod 32 to disengage from the inclined surface. Under the action of the fourth return spring 33, the push rod 32 is retracted, causing the positioning plate 31 to automatically retract, thus relaxing the positioning mechanism 3.

[0038] In this embodiment, the vehicle fixture positioning device drives the driving mechanism 2 to move the positioning mechanism 3 toward the center of the positioning slot 11, thereby achieving automatic positioning and clamping of the corner of the vehicle fixture. At the same time, only the driving mechanism 2 needs to be driven to release the positioning mechanism 3, thus achieving automatic release after clamping the corner of the vehicle fixture, which is convenient to operate.
