[0027] Embodiment
[0028] Please refer to Figure 1 and Figure 2 As shown, the present utility model discloses a calibration inspection tooling for a connecting rod, which includes a tooling bottom plate 100, a calibration unit 200, and an inspection unit 300. The inspection unit 300 is used to inspect whether the deformation amount of the connecting rod 500 meets the standard, and the calibration unit 200 is used to calibrate the deformation of the connecting rod 500. Both the calibration unit 200 and the inspection unit 300 are fixedly installed on the tooling bottom plate 100.
[0029] Specifically, please refer to Figure 1As shown in the figure, in the present utility model, the calibration unit 200 includes a base 210, a quick clamp 220, a second positioning pin 230, a second column 240, and a deformation groove 250. The base 210 and the second column 240 are both welded and fixed on the tooling base plate 100. The second positioning pin 230 is vertically installed on the base 210 to insert into the pin hole of the connecting rod 500, which can accurately position the placement position of the connecting rod 500. In this embodiment, the number of the second positioning pins 230 is two, and the two second positioning pins 230 respectively correspond to the pin holes at the front and rear ends of the connecting rod 500, further improving the positioning effect on the connecting rod 500. A deformation groove 250 corresponding to the calibration section 510 of the connecting rod 500 is provided on the base 210. In this embodiment, the opening range of the deformation groove 250 covers the deformation groove 250 and extends to the front side of the connecting rod 500. The side wall of the deformation groove 250 and the front side of the connecting rod 500 are located in the same vertical plane. The deformation groove 250 provides a downward space for the correction section of the connecting rod 500 and plays a positioning role. Through the positional relationship between the front side of the connecting rod 500 and the side wall of the deformation groove 250, it can be directly judged whether the position of the connecting rod 500 is accurate. Further, the deformation groove 250 covers the length adjustment section 520 of the connecting rod 500, providing a clearance for the length adjustment section 520 to avoid interference between the nut of the length adjustment section 520 and the base 210, which affects the calibration of the connecting rod 500. The quick clamp 220 is opposite to the calibration section 510 of the connecting rod 500 and is installed on the second column 240, used to quickly clamp the connecting rod 500 and make the connecting rod 500 deform to calibrate the connecting rod 500. In this embodiment, the calibration unit 200 further includes a second quick clamp 260, and the number of the second columns 204 is two. The quick clamp 220 and the second quick clamp 260 are respectively fixed on the two second columns 240. The second quick clamp 260 corresponds to the front end position of the connecting rod 500. The second quick clamp 260 presses and limits the front end of the connecting rod 500 to ensure that the front end of the connecting rod 500 remains stable during the calibration process and avoid the front end from warping up, which affects the calibration effect. An installation seat 400 is fixed on the side of the tooling base plate 100 where the base 210 is located. A universal connecting rod 410 is ball-jointed on the installation seat 400, and a refractive mirror 420 is ball-jointed at the free end of the universal connecting rod 410. Workers can adjust the vertical height, front and rear positions, left and right positions, and angles of the refractive mirror 420 through the ball-jointed structure and the universal connecting rod, which is convenient for workers to directly master the calibration situation of the connecting rod 500 without the need for workers to look straight at the correction section of the connecting rod 500, improving the calibration efficiency.
[0030] Please refer to Figure 1 and Figure 2As shown in the figure, in the present utility model, the inspection unit 300 includes a positioning seat 310, a quick push clamp 320, a first positioning pin 330, and a first column 360. The positioning seat 310 is fixedly installed on the tooling bottom plate 100; the positioning seat 310 is provided with a first positioning surface 340 to position the side surface of the connecting rod 500. Whether the deformation amount of the connecting rod 500 meets the standard is judged by the degree of fit between the connecting rod 500 and the first positioning surface 340. In this embodiment, the first positioning surface 340 is an "L"-shaped positioning surface, and the bottom surface and the side surface of the "L"-shaped positioning surface are respectively in contact and positioned with the bottom surface and the side surface of the connecting rod 500. The first positioning pin 330 is vertically installed on the first positioning surface 340 to position the pin hole of the connecting rod 500. In this embodiment, the number of the first positioning pins 330 is two, and the two first positioning pins respectively correspond to the pin holes at the front and rear ends of the connecting rod 500, further improving the positioning effect on the connecting rod 500. And the pin diameter of the first positioning pin 330 is larger than the pin diameter of the second positioning pin 230. The design is that when the connecting rod 500 is deformed, the central axes of the two pin holes of the connecting rod 500 are not parallel but have a spatial intersection. The second positioning pin 230 with a small pin diameter can position the pin hole of the deformed connecting rod 500, and the first positioning pin 330 with a large pin diameter can correct the accuracy problem caused by the error, effectively improving the accuracy of the calibration inspection. An adjustment notch 350 corresponding to the length adjustment section 520 of the connecting rod 500 is formed on the positioning seat 310; it is convenient for workers to adjust the length adjustment section 520 of the connecting rod 500 and adjust the length of the connecting rod 500. The first column 360 is fixedly installed on the tooling bottom plate 100 and is located on the side of the positioning seat 310. The height of the first column 360 is higher than that of the second column 240, and the quick push clamp 320 is installed on the first column 360. The quick push clamp 320 is arranged to push and clamp towards the first positioning surface 340, and is designed according to ergonomics and force analysis. The advantage is that when a person stands, a thrust can be effectively applied to the quick push clamp 320, and when a person is in a semi-squat state, a greater pressure can be more effectively applied to the quick press clamp 220, and the pressure specification of the quick press clamp 220 is greater than the thrust specification of the quick push clamp 320 so that workers can apply a greater pressure to correct the connecting rod 500, thus greatly reducing the burden on workers and improving work efficiency. In this embodiment, the number of the first positioning columns 360 and the quick push clamps 320 are both two. The two first positioning columns 360 respectively correspond to the front end and the rear end positions of the connecting rod 500. The two quick push clamps 320 are respectively fixed on the two first positioning columns 360, and push and position the front end and the rear end of the connecting rod 500, ensuring the stability of the connecting rod 500 on the positioning seat 310 and improving the inspection accuracy.
