[0025] As shown in Figures 1 to 5 A valve plunger detection device, comprising a bottom plate 1, the top of the bottom plate 1 is fixedly connected with a chassis 3, the top outer side of the chassis 3 is rotatably connected with a turntable 4, the top surface of the turntable 4 is fixedly connected with multiple placement plates 8, multiple placement cavities 801 for placing plunger bodies 802 are formed in the placement plates 8, an L-shaped support 2 is connected to the outer side of the bottom plate 1, a measuring block 14 corresponding to the position of the placement cavity 801 is connected to the L-shaped support 2, an inner measuring structure is slidably connected in the measuring block 14, a scale mark is arranged on the outer side of the measuring block 14 and the inner measuring structure, and a pressing assembly is connected to the top of the measuring block 14.
[0026] As shown in Figure 1 The valve plunger detection device in the utility model is similar in structure to the existing detection device for automobile valve plunger, and a patent with publication number CN220472500U discloses a detection device for automobile valve plunger, and the main improvement point of the utility model is to facilitate improving the detection efficiency during valve plunger detection, and Figures 1 to 5As shown, when the tappet body 802 needs to be detected, the tappet body 802 is placed in the plurality of placement cavities 801 in the placement plate 8, so that the tappet body 802 is just located in the placement cavity 801, and with the rotation of the turntable 4, the placement plate 8 with the tappet body 802 is just rotated to the lower end of the measuring block 14. Under the action of the pressing assembly, the measuring block 14 moves downward, so that the measuring block 14 just extends into the boss in the tappet body 802. At this time, since the outer side of the measuring block 14 is provided with a scale mark, the worker can conveniently measure the height of the boss to the upper surface of the tappet body 802 through the scale mark. When the bottom surface of the measuring block 14 is attached to the boss of the tappet body 802, the bottom surface of the inner measuring structure is also attached to the inner bottom surface of the tappet body 802, so that the height inside the tappet body 802 can be detected.
[0027] During the detection process, the worker can place the tappet body 802 in the placement cavity 801 of the other placement plate 8 on the turntable 4. After the detection of the previous group is completed, the pressing assembly moves upward, so that the measuring block 14 moves upward. At this time, the turntable 4 is rotated again, so that the tappet body 802 to be detected is rotated to the lower side of the measuring block 14. In this way, the process is repeated.
[0028] By arranging a plurality of placement plates 8 on the turntable 4 and arranging a plurality of placement cavities 801 on the placement plate 8, a plurality of tappet bodies 802 can be detected at one time, and the detection efficiency is improved. At the same time, during the detection process, the feeding and discharging of the tappet body 802 are completed, which saves operation time and effectively improves work efficiency. The measuring block 14, the inner measuring structure and the scale mark are used to measure the height of the boss of the tappet body 802 and the height of the boss to the upper surface at one time, so that two kinds of detection are realized, and the detection efficiency is further improved.
[0029] As shown in Figure 3 , Figure 4 and Figure 5 , the inner measuring structure comprises a measuring ring 15 and two vertical plates 18. The bottom of the measuring block 14 is provided with an annular groove 16, and the top is provided with two vertical grooves 17 which are in communication with the annular groove 16. The measuring ring 15 is slidably connected in the annular groove 16, and the top of the measuring ring 15 is fixedly connected with the vertical plate 18 which is slidably connected in the vertical groove 17.
[0030] Specifically, when the measuring block 14 extends into the tappet body 802, the bottom surface will be attached to the boss of the tappet body 802. At this time, the bottom surface of the measuring ring 15 is attached to the inner bottom surface of the tappet body 802 under the sliding of the vertical plate 18. Since the outer wall of the measuring ring 15 and the vertical plate 18 is provided with a scale mark, the height value of the vertical plate 18 extending out of the top surface of the measuring block 14 can be read, and the height measurement of the boss is realized.
[0031] As shown in Figure 1 andFigure 3 As shown in the drawings, the pressing assembly comprises an electric push rod 9, the output end of the electric push rod 9 is fixedly connected with an integrated plate 10, the bottom of the integrated plate 10 is fixedly connected with a plurality of telescopic members, each telescopic member is connected with the measuring block 14.
[0032] Specifically, when the placing plate 8 rotates to the position below the measuring block 14 along with the rotation of the rotating disc 4, the output end 9 of the electric push rod is pushed to drive the three telescopic members at the bottom of the integrated plate 10 to descend, thereby driving the measuring block 14 to move up and down for detection.
[0033] As shown in the drawings, Figure 4 and Figure 5 The telescopic member comprises a connecting rod 12 and a sliding rod 13, the sliding rod 13 is slidingly connected in the connecting rod 12, the bottom of the sliding rod 13 is fixedly connected with the top of the measuring block 14, the L-shaped support 2 is fixedly connected with a horizontal plate 201, the connecting rod 12 penetrates through the horizontal plate 201 and is slidingly connected therewith.
[0034] Specifically, in order to avoid the damage to the measuring block 14, the sliding rod 13 will sag in the connecting rod 12 under the action of gravity in the normal state, and when the bottom surface of the measuring block 14 is in contact with the top surface of the boss in the plunger body 802, the sliding rod 13 will slide in the connecting rod 12, preventing the force of the electric push rod 9 from directly pressing the bottom surface of the measuring block 14 to damage the plunger body 802 or cause damage to itself.
[0035] As shown in the drawings, Figure 1 and Figure 2 The outer side of the rotating disc 4 is connected with a transmission assembly, the transmission assembly comprises a stepping motor 5, the output end of the stepping motor 5 is fixedly connected with a main gear 6, the outer side of the rotating disc 4 is fixedly connected with a slave gear 7 which is in meshing connection with the main gear 6.
[0036] Specifically, when the rotating disc 4 needs to rotate, the stepping motor 5 rotates to drive the main gear 6 to rotate, the main gear 6 is in meshing transmission with the slave gear 7, and the slave gear 7 drives the rotating disc 4 to rotate.
[0037] As shown in the drawings, Figure 4 and Figure 5 The top of the two vertical plates 18 is fixedly connected with an anti-disengagement plate 19, the end of the anti-disengagement plate 19 close to the sliding rod 13 is in contact with the outer wall of the sliding rod 13. The anti-disengagement plate 19 can prevent the vertical plate 18 from disengaging from the measuring block 14, thereby preventing the measuring ring 15 from falling off.
[0038] As shown in the drawings, Figure 2 The inner wall of the bottom disc 3 is embedded with a plurality of rolling balls 301, the rolling balls 301 are slidingly and rotatably connected with the inner wall of the rotating disc 4. When the rotating disc 4 rotates, the rolling balls 301 can convert the sliding friction into rolling friction when the rotating disc 4 and the bottom disc 3 rotate, thereby reducing the resistance.
[0039] AsFigure 1 and Figure 2 As shown in FIG. 1, the placing plate 8 is detachably connected with the top of the rotating disc 4. The installation and dismounting of the placing plate 8 are facilitated.
[0040] As shown in FIG. 1, the placing plate 8 is detachably connected with the top of the rotating disc 4. The installation and dismounting of the placing plate 8 are facilitated.
