Description

Technical Field

[0001] The utility model belongs to the field of processing equipment, relates to leather roller processing equipment, and specifically relates to a fixing device used for roller skin processing. Background Art

[0002] When processing the roller skin, it is usually necessary to quench it to improve its hardness and strength. When quenching the roller skin, it is necessary to hoist the roller skin to heat it, and then hang it into the quenching liquid to cool it quickly.

[0003] At present, when using lifting equipment to lift the roller skin, since there is no lifting point on the roller skin, a lifting chain is usually used to bypass the roller skin and lift it. The lifting chain contacts the roller skin, which will cause wear to the roller skin. If the roller skin is lifted by using a plate, the roller skin is placed on the plate, and a lifting point is set on the plate to lift it. If the plate supports the roller skin on different axes, it is very easy to cause the roller skin to deviate along the plate when lifting it, and there is usually no limiter on the plate, which can easily cause the plate to sink and the roller skin to be damaged. If the position of the roller skin is adjusted, the operation is time-consuming and labor-intensive. Utility Model Content

[0004] In order to solve the technical problem that the roller skin is easily damaged when it is not restricted during hoisting, the utility model provides a fixing device for roller skin processing.

[0016] The support rod is positioned by plugging into the positioning rod through the positioning groove on its outer wall. The outer side of the positioning groove is a wide-mouth groove to increase the contact area with the positioning rod, so that the positioning rod is poured into the positioning groove. The inner side is a cylindrical groove to facilitate plugging with the positioning rod and friction fixing. The friction contact strength is improved by the interference fit to improve the firmness of the connection.

[0017] To further optimize the technical solution, the interference piece includes an interference ring fixedly sleeved on the outer wall of the positioning rod and an annular interference groove opened on the inner wall of the cylindrical groove, and the interference ring is clamped with the interference groove.

[0018] When the positioning rod is plugged into the cylindrical groove on the support rod, the interference ring on the positioning rod is engaged with the interference groove on the cylindrical groove, thereby improving the firmness of the plugging of the positioning rod and the support rod.

[0019] To further optimize the technical solution, the inner ring wall of the support ring is sleeved with a bearing, and the bearing is sleeved with the suspension rod.

[0020] The support ring is rotatably assembled with the hanger rod by means of a bearing, so that when the sleeve is rotated to be threadedly connected with the hanger rod, the support ring abuts against the support rod, reducing the rotation of the support ring, thereby reducing the contact wear with the support rod and extending its service life.

[0021] To further optimize the technical solution, the top of the sleeve and the top of the suspension rod are both fixedly mounted with lifting rings.

[0022] The sleeve and the lifting rod are hoisted with the help of lifting rings, which is easy to use and stable.
