DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 5 As shown, a cylinder head processing and positioning tool described in the utility model includes a workbench 1, a bidirectional screw 2 is rotatably installed in the workbench 1, the threads at both ends of the bidirectional screw 2 are in opposite directions, two screw sleeves 21 are threadedly installed at both ends of the bidirectional screw 2, a first gear 23 is fixedly installed in the middle of the bidirectional screw 2, two first tooth plates 24 are meshed and installed above and below the first gear 23, and the two first tooth plates 24 are slidably installed inside the workbench 1, and a first clamping block 3 and a second clamping block 33 are arranged above the workbench 1.

[0023] During the rotation of the bidirectional screw rod 2, the screw rod sleeves 21 at both ends can be driven to rotate in opposite directions, and at the same time, the first gear 23 located in the middle of the bidirectional screw rod 2 can be driven to rotate. The rotation of the first gear 23 can drive the first tooth plates 24 above and below the first gear 23 to slide, and then through the sliding of the two first tooth plates 24, the second clamping blocks 33 located in four directions can be moved simultaneously to achieve the clamping and positioning operation of the cylinder head. During this process, the operator only needs to turn the handle to drive the second clamping blocks 33 in four directions to move through linkage, saving a lot of manpower.

[0024] Specifically, sliders 22 are fixed on the two screw sleeves 21 and the two first tooth plates 24, and sliding grooves are provided on the workbench 1 corresponding to the four sliders 22, in which the sliders 22 can slide. The first tooth plate 24 above the first gear 23 is provided with a groove, which cooperates with the slider 22 fixed on the other first tooth plate 24 to be embedded.

[0025] During the relative movement of the two first tooth plates 24, the slider 22 fixed on the lower first tooth plate 24 can be embedded in the groove of the upper first tooth plate 24 to avoid collision between the upper first tooth plate 24 and the slider 22.

[0026] Specifically, a base 31 is fixed on the top of the slider 22, a second tooth plate 32 is slidably mounted on the side wall of the base 31, the second tooth plate 32 extends through the side wall of the base 31, and the second clamping block 33 is fixed at the end of the second tooth plate 32 away from the base 31.

[0027] Specifically, a second gear 34 is rotatably installed in the base 31, and the second tooth plate 32 is meshed with the second gear 34. A third tooth plate 35 is slidably installed on the top of the base 31, and the third tooth plate 35 is meshed with the second gear 34. The first clamping block 3 is fixed to the end of the third tooth plate 35 that passes through the base 31.

[0028] During operation, when the second clamping block 33 contacts the cylinder, continue to turn the handle 4, and then the second clamping block 33 will push the second tooth plate 32 to slide into the base 31, and then the second tooth plate 32 will drive the second gear 34 to rotate, and the second gear 34 will drive the third tooth plate 35 to slide downward, and then the third tooth plate 35 will drive the first clamping block 3 to move downward, thereby realizing the positioning of the cylinder head in the up and down directions.

[0029] Specifically, a telescopic rod 36 is fixed to the end of the second tooth plate 32 located in the base 31, and the other end of the telescopic rod 36 away from the second tooth plate 32 is fixed to the inner wall of the base 31. A spring 37 is provided on the outer sleeve of the telescopic rod 36, and the two ends of the spring 37 are fixedly connected to the side wall of the second tooth plate 32 and the inner wall of the base 31 respectively.

[0030] After the cylinder head processing operation is completed, the handle 4 is rotated in the reverse direction to release the positioning of the cylinder head. At this time, due to the elastic potential energy of the spring 37, the second tooth plate 32 can be pushed to slide away from the base 31, and then the second tooth plate 32 can drive the second gear 34 to rotate. At this time, the second gear 34 can drive the third tooth plate 35 to slide upward, and then drive the first clamping block 3 to move upward, thereby releasing the positioning of the cylinder head in the up and down directions.

[0031] Specifically, one end of the bidirectional screw rod 2 extends through the workbench 1 and is fixedly connected to the turning handle 4 .

[0032] Working principle: During positioning operation, the cylinder head is placed in the middle of the workbench 1, and the operator holds the turning handle 4 and turns it, and then the turning handle 4 drives the two-way screw rod 2 to rotate, and then the two-way screw rod 2 drives the two screw rod sleeves 21 to rotate. Since the threads at both ends of the two-way screw rod 2 are opposite, the two screw rod sleeves 21 move in the direction of approaching each other, and then drive the slider 22 fixed on the screw rod sleeve 21 to slide, and at the same time, the first gear 23 in the middle of the two-way screw rod 2 rotates, driving the first toothed plates 24 located above and below the first gear 23 to slide, and the two first toothed plates 24 drive The slider 22 on the first tooth plate 24 slides, and then the four sliders 22 drive the four bases 31 to move. When the second clamping block 33 contacts the side wall of the cylinder, the turning handle 4 continues to be turned. At this time, the four second clamping blocks 33 respectively push the second tooth plate 32 fixedly connected thereto to slide, and the second tooth plate 32 drives the second gear 34 to rotate, and then the second gear 34 drives the third tooth plate 35 to slide, and then the third tooth plate 35 will drive the first clamping block 3 to move downward, thereby realizing the positioning of the cylinder head in the up and down directions. After the positioning is completed, the cylinder head can be processed.

[0033] It should be mentioned that after the processing operation is completed, the cylinder head can be released from the positioning by rotating the handle 4 in the opposite direction. At this time, due to the elastic potential energy of the spring 37, the second tooth plate 32 can be pushed to slide away from the base 31, and then the second tooth plate 32 can drive the second gear 34 to rotate. At this time, the second gear 34 can drive the third tooth plate 35 to slide upward, and then drive the first clamping block 3 to move upward, thereby releasing the positioning of the cylinder head in the up and down directions.
