The utility model discloses a positioning inspection fixture, which relates to the technical field of clamping equipment, including a workbench; a pair of slides and a first driving mechanism capable of driving the pair of slides to move closer to each other are slidably provided on the top of the workbench; a clamping plate is provided on the top of the pair of slides; auxiliary clips are provided on the opposite sides of the pair of clamping plates; two auxiliary clips are symmetrically provided on each clamping plate, and the ends of the two auxiliary clips that are away from each other are curved and gathered in an arc shape toward the middle of the clamping plate. The utility model has a reasonable structure, and a pair of auxiliary clips are provided on the clamping plate to be able to rotate and expand and rotate and retract the auxiliary clips, and the arc bending structure of the pair of auxiliary clips that are away from each other can be used to fit and clamp the arc sides of car seats of different sizes, so as to achieve effective clamping and positioning of the car seats, and avoid the problem of eccentric shaking during the quality inspection of car seats as much as possible, and provide favorable conditions for the quality inspection of car seats.

In addition, the curved panels used to fit and fix the seat did not conform to the relatively square shape of the car seat itself, and the firmness during fitting and clamping was poor. In view of the above problems, the solution needs to be optimized and improved. Utility Model Content

[0025] Please see all instructions drawings:

[0026] A positioning structure for a gauge comprises a workbench 1, a control button 2 is arranged on the workbench 1, a transverse clamping mechanism is arranged on the workbench 1, and a longitudinal clamping mechanism is arranged on the transverse clamping mechanism;

[0027] The horizontal clamping mechanism includes a through hole 3 located in the workbench 1. A double-threaded screw rod 4 is rotatably connected in the through hole 3. One side of the workbench 1 is fixedly installed with a first motor 5. The output end of the first motor 5 is fixedly connected to the double-threaded screw rod 4. Symmetrically threaded connections are provided on the double-threaded screw rod 4 with sliding plates 6. The sliding plates 6 extend out of one end of the workbench 1 through the through hole 3 and are fixedly installed with clamping plates 7; the longitudinal clamping mechanism includes a first groove 8 located on the mutually remote sides of the clamping plate 7. A double-threaded screw rod 9 is rotatably connected in the first groove 8. One side of the clamping plate 7 is fixedly installed with a second motor 10. The output end of the second motor 10 is fixedly connected to the double-threaded screw rod 9. Threaded connections are provided on the double-threaded screw rod 9 with clamping rods 11. Strip-shaped through holes 12 are provided on the opposite surfaces of the clamping plate 7. One end of the clamping rod 11 extending out of the clamping plate 7 through the strip-shaped through hole 12 is provided with a second groove 13. A rotating shaft 14 is fixedly installed in the second groove 13. A V-shaped rod 15 is rotatably connected to the rotating shaft 14. Fixed wheels 16 are symmetrically rotatably connected to the V-shaped rod 15;

[0028] As can be seen from the above description, after the seat is placed on the workbench 1, by controlling the operation of the first motor 5, the double-threaded screw rod 4 rotates, driving the sliding plates 6 to approach each other. First, the two sides of the seat are clamped by the sliding plates 7 and the clamping plates 7. Then, by controlling the operation of the two motors 10, the double-threaded screw rod 9 rotates, driving the four clamping rods 11 to approach each other in pairs. When the fixed wheels 16 come into contact with the seat, through the adaptive rotation of the V-shaped rod 15, the fixed wheels 16 on both sides can be well attached and pressed against the seat, and finally the stable fixation of the seat is achieved.

[0029] As a technical optimization scheme of the present utility model, the control button 2 is electrically connected to the first motor 5 and the second motor 10;

[0030] As can be seen from the above description, when the worker is operating, by controlling the control button 2, the rapid fixation of the seat can be achieved.

[0031] As a technical optimization scheme of the present utility model, symmetrically provided at one end of the sliding plate 6 located in the through hole 3 are third grooves 17. Rotating wheels 18 are rotatably connected in the third grooves 17. The rotating wheels 18 are in sliding connection with the inner wall of the through hole 3;

[0032] As can be seen from the above description, through the contact between the rotating wheels 18 and the inner wall of the through hole 3, the transverse movement of the sliding plate 6 becomes smoother.

[0033] As a technical optimization scheme of the present utility model, the sliding plate 6 is in a square frame shape;

[0034] As can be seen from the above description, the square frame shape design makes the integrity of the sliding plate 6 on the workbench 1 better.

[0035] As a technical optimization solution of the utility model, a limit rod 19 is symmetrically fixedly installed in the through hole 3 corresponding to the double-threaded screw rod 14, and the limit rod 19 is plug-connected with the slide plate 6;

[0036] It can be seen from the above description that the setting of the limiting rod 19 makes the sliding stability of the slide plate 6 better.

[0037] As a technical optimization solution of the utility model, the V-shaped rod 15 is slidably connected to the inner wall of the second groove 13;

[0038] It can be seen from the above description that the V-shaped rod 15 is slidably connected to the inner wall of the second groove 13, so that the rotation of the V-shaped rod 15 when clamping the seat is more stable.

[0039] As a technical optimization solution of the utility model, the clamping rod 11 is slidably connected with the strip-shaped through hole 12;

[0040] It can be seen from the above description that the sliding connection between the clamping rod 11 and the strip-shaped through hole 12 can make the clamping rod 11 more stable when moving laterally.

[0041] As a technical optimization solution of the utility model, a rubber pad 20 is provided on the workbench 1;

[0042] It can be seen from the above description that the rubber pad 20 can further improve the safety between the workbench 1 and the car seat and avoid hard contact.

[0043] Working principle:

[0044] After placing the seat on the workbench 1, the worker operates the control button 2 to control the motor 1 5 to make the double-threaded screw 1 4 rotate, driving the slide plates 6 to approach each other, first clamping the two sides of the seat through the slide plate 7 and the clamping plate 7, and then controlling the two motors 10 to make the double-threaded screw 2 9 rotate, driving the four clamping rods 11 to approach each other in pairs. When the fixed wheel 16 contacts the seat, the V-shaped rod 15 rotates adaptively, so that the fixed wheels 16 on both sides can be well pressed on the seat, and finally the stable fixation of the seat is achieved.

[0045] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
