They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, a clamp device 100 for preventing steel balls from entering the inner wall of an I-shaped wheel 101 during shot blasting comprises: a first pressing block 1, a first limiting block 2, a pin 3, a second pressing block 4, a second limiting block 5 and a locking cap 6.

[0023] The first pressing block 1 , the first limiting block 2 and the pin shaft 3 are connected in sequence along the first direction X.

[0024] The locking cap 6 and the second limiting block 4 are respectively located on two sides of the second pressing block 5 along the first direction X, wherein the second limiting block 5 is connected to the second pressing block 4 .

[0025] When clamping, the pin shaft 3 passes through the spool middle tube 103, the second limit block 5 and the second pressure block 4 in sequence along the first direction X and is then locked and fixed in the locking cap 6. The end faces of the first pressure block 1 and the second pressure block 4 perpendicular to the first direction X respectively cover the end faces on both sides of the spool pin hole 102 after clamping. At the same time, the first limit block 2 and the second limit block 5 are respectively inserted into the two ends of the spool pin hole 102 to limit the large sliding of the first pressure block 1 and the second pressure block 4 on the end face of the spool 101. This can effectively prevent the first pressure block 1 and the second pressure block 4 from sliding relative to the end face of the spool 101 and failing to cover the spool pin hole 102.

[0026] Optionally, the center lines of the first pressing block 1, the first limiting block 2 and the pin 3 parallel to the first direction X coincide with each other. This arrangement facilitates processing and size optimization, saving materials.

[0027] Optionally, the first pressing block 1, the first limiting block 2 and the pin 3 are an integrated structure, which is convenient for improving the coaxiality of the three and facilitating integrated processing and molding.

[0028] Optionally, center lines of the second pressing block 4 and the second limiting block 5 parallel to the first direction X coincide with each other.

[0029] Optionally, the second pressing block 4 and the second limiting block 5 are an integrated structure, which is convenient for improving the coaxiality of the second pressing block and the second limiting block and is convenient for integrated processing and molding.

[0030] Optionally, the cross-sectional shapes of the first pressing block 1 and the second pressing block 4 perpendicular to the first direction X are similar to the end surface shapes on both sides of the I-shaped wheel pin hole 102, the cross-sectional sizes of the first pressing block 1 and the second pressing block 4 perpendicular to the first direction X are the same, and the spacing between the cross-sectional outer contours of the first pressing block 1 and the second pressing block 4 and the end surface outer contours of the I-shaped wheel pin hole 102 is equal to 5 mm everywhere. This arrangement can well cover the I-shaped wheel pin hole, prevent the steel column from entering the I-shaped wheel middle tube, and can also well save processing materials.

[0031] Preferably, the cross-sectional shapes of the first limit block 2 and the second limit block 5 perpendicular to the first direction X are similar to the end surface shapes on both sides of the spool pin hole 102, the cross-sectional sizes of the first limit block 2 and the second limit block 5 perpendicular to the first direction X are the same, and the spacing between the cross-sectional outer contours of the first limit block 2 and the second limit block 5 and the end surface outer contours of the spool pin hole 102 is equal to 2 mm everywhere. This arrangement can not only facilitate the insertion and removal of the first limit block and the second limit block in the spool pin hole, but also effectively limit the sliding of the first pressure block and the second pressure block on the end surface of the spool.

[0032] Optionally, the sum of the length of the spool middle cylinder 103 along the first direction X, the thickness of the second pressure block 4 along the first direction X, and the thickness of the second stopper 5 along the first direction X is less than the length of the pin shaft 3 along the first direction X, and the sum of the length of the spool middle cylinder 103 along the first direction X, the thickness of the second pressure block 4 along the first direction X, the thickness of the second stopper 5 along the first direction X, and the thickness of the locking cap 6 along the first direction X is greater than or equal to the length of the pin shaft 3 along the first direction X. This arrangement not only facilitates the central pin shaft to stably fix the two pressure blocks on both sides of the spool pin hole, but also saves space.

[0033] Optionally, the pin 3 and the locking cap 6 are threadedly connected. This arrangement facilitates disassembly.

[0034] Optionally, the first pressing block 1, the first limiting block 2, the pin 3, the second pressing block 4, the second limiting block 5 and the locking cap 6 are all made of 304 stainless steel. 304 stainless steel is relatively wear-resistant and corrosion-resistant, and can well ensure the service life of the clamp device.
