Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The embodiment of the present utility model discloses a multi-point composite detection device for the inner hole and end face of a cylinder head.

[0027] The present utility model provides a Figures 1 - 3 multi-point composite detection device for the inner hole and end face of a cylinder head as shown in the figure, including a support frame 1. Driving screws 2 are rotatably penetrated through both sides of the support frame 1. Extrusion tubes 3 are sleeved on the screw threads of the rod walls of the two driving screws 2. Both sides of the inner wall of the support frame 1 are jointly provided with a swivel ring 4 through a rotating mechanism. The rotating mechanism includes a first annular plate 7. The first annular plate 7 is fixedly arranged on the inner wall of the support frame 1 and has an annular groove formed therein. A second annular plate 8 is fixedly sleeved on the outer wall of the swivel ring 4. The second annular plate 8 is rotatably arranged in the annular groove. A detection camera 5 is fixedly arranged on the inner wall of the swivel ring 4. An image analysis platform 6 is fixedly arranged at the upper end of the outer wall of the support frame 1;

[0028] A reciprocating drive detection mechanism is arranged at the lower end of the outer wall of the swivel ring 4. The reciprocating drive detection mechanism includes a rack 13. A groove is formed at the bottom of the inner wall of the support frame 1. A reciprocating lead screw 14 is rotatably arranged in the groove. A motor 15 is fixedly arranged at the lower end of the back side of the support frame 1. The output shaft of the motor 15 penetrates into the groove and is fixedly connected with the reciprocating lead screw 14. A slider 16 is sleeved on the screw thread of the rod wall of the reciprocating lead screw 14. The rack 13 is fixedly connected to the top of the slider 16 and is cooperatively provided with a gear ring 17. The gear ring 17 is fixedly sleeved with the swivel ring 4.

[0029] Before inspecting the cylinder head, the cylinder head is placed in the rotating ring 4 and the two driving screws 2 are rotated. At this time, the driving screws 2 drive the extrusion tube 3 to move horizontally and extrude and position the cylinder head. Then the inspection camera 5 is turned on and connected to the image analysis platform 6. Then, with the rotation cooperation of the second annular plate 8 and the annular groove, the rotating ring 4 drives the inspection camera 5 to rotate and effectively inspect the inner and outer holes and end faces of the cylinder head, thereby improving the inspection efficiency and reducing the use of inspection components.

[0030] In order to drive the swivel 4 to rotate stably, after the position of the cylinder head is fixed, the motor 15 is started to rotate the reciprocating screw 14. At this time, the reciprocating screw 14 drives the slider 16 to move back and forth laterally in the groove, so that the rack 13 moves horizontally accordingly. Through the cooperation of the rack 13 and the ring gear 17, the ring gear 17 can drive the swivel 4 to rotate stably, thereby driving the detection camera 5 to perform the surrounding detection work.

[0031] In order to simultaneously drive the two extrusion tubes 3 to move laterally and stably clamp and position the cylinder cover, as shown in FIG. Figure 1 As shown, a guide rod 18 is fixedly penetrated through the side of the support frame 1, and the guide rod 18 is slidably arranged inside the extrusion tube 3. A synchronous drive clamping mechanism is commonly provided between the two driving screws 2 and the support frame 1. The synchronous drive clamping mechanism includes a cross bar 9, and the cross bar 9 is rotatably arranged inside the lower end of the support frame 1. Both ends of the cross bar 9 are fixedly sleeved with a first synchronous wheel 10, and the rod walls of the two driving screws 2 are fixedly sleeved with a second synchronous wheel 11. A synchronous belt 12 is transmitted between the first synchronous wheel 10 and the second synchronous wheel 11. A through hole for cooperating with the transmission of the synchronous belt 12 is opened at the lower end of the support frame 1, and a crank 19 is fixedly provided at the end of the cross bar 9.

[0032] Before testing the cylinder head, place the cylinder head in the rotating ring 4 and turn the crank 19. At this time, the crank 19 drives the cross bar 9 to rotate. At this time, under the transmission of the first synchronous wheel 10, the second synchronous wheel 11 and the synchronous belt 12, the two driving screws 2 rotate at the same time. At the same time, under the support of the guide rod 18, the two extrusion tubes 3 move at the same time and approach each other, so as to quickly extrude and position the cylinder head.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
