Description

Technical Field

[0001] The utility model relates to the technical field of bactericides, in particular to a blank roller clamping tool for machine tools. Background Art

[0002] At present, the split traction roller cannot be used directly on the line when it is in the state of a blank roller, and needs to be turned and finished on the surface before use. The existing processing method is to use the machine tool chuck to directly clamp the tail end of the blank roller and then process it. However, this clamping method has the following problems.

[0003] However, during processing, workers need to operate the gantry crane equipment to clamp the blank roller on the chuck to ensure that it is coaxial with the chuck. The process of adjusting the coaxiality between the blank roller and the chuck is difficult and time-consuming, resulting in low processing efficiency. In addition, the positions available for clamping the blank roller are limited. If the blank roller is clamped without being pre-positioned, it will lead to loose clamping and there is a risk of the blank roller falling off when the machine tool rotates.

[0004] Therefore, we propose a blank roll clamping fixture for machine tools to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model provides a technical solution: a blank roller clamping tool for a machine tool, comprising a base 1 and a blank roller 2 arranged above the base 1, the base 1 provides support for a support seat 3 and a support plate 5 on the top, and the blank roller 2 passes through a through groove 9 opened on the surface of the support plate 5 and is partially inserted into an insertion groove 6 opened on the surface of a chuck 4. The two ends of the blank roller 2 are partially located in the insertion groove 6 opened on the surface of the chuck 4 and partially located in the through groove 9 opened on the surface of the support plate 5.

[0022] For details, please refer to Figure 1-3 When the blank roller 2 is located at the predetermined position, the blank roller 2 touches the trigger switch 14 fixedly connected to the inner wall of the insertion groove 6, and the trigger switch 14 and the first telescopic cylinder 12 are connected by signal with the second telescopic cylinder 13. The first telescopic cylinder 12 arranged in the placement groove 7 and the second telescopic cylinder 13 arranged in the installation groove 10 start to push the first locking semi-ring 8 and the second locking semi-ring 11 at the top to move upward, and the two ends of the blank roller 2 are clamped and fixed by the two groups of first locking semi-rings 8 and the two groups of second locking semi-rings 11, so as to realize the locking and installation of the blank roller 2. At the same time, when the blank roller 2 passes through the through groove 9 opened on the surface of the support plate 5, it also passes through the limiting ring 15, and the cleaning strip 16 fixedly connected to the inner wall of the limiting ring 15 wipes the surface of the blank roller 2.

[0023] Working principle: the base 1 provides support for the support seat 3 and the support plate 5 at the top. After the blank roller 2 passes through the through groove 9 opened on the surface of the support plate 5 and is partially inserted into the insertion groove 6 opened on the surface of the chuck 4, both ends of the blank roller 2 are partially located in the insertion groove 6 opened on the surface of the chuck 4 and partially located in the through groove 9 opened on the surface of the support plate 5. When the blank roller 2 is located at the predetermined position, the blank roller 2 touches the trigger switch 14 fixedly connected to the inner wall of the insertion groove 6. The trigger switch 14 and the first telescopic cylinder 12 are connected by signal with the second telescopic cylinder 13. The first telescopic cylinder 12 set in the placement groove 7 and the second telescopic cylinder 13 set in the installation groove 10 start to push the first locking semi-ring 8 and the second locking semi-ring 11 on the top to move upward. Through the two sets of first locking semi-rings The ring 8 and the two sets of second locking half rings 11 clamp and fix the two ends of the blank roller 2, thereby locking and installing the blank roller 2. At the same time, when the blank roller 2 passes through the through groove 9 opened on the surface of the support plate 5, it also passes through the limiting ring 15. The cleaning strip 16 fixedly connected to the inner wall of the limiting ring 15 wipes the surface of the blank roller 2, which solves the problem that during processing, workers need to operate the gantry crane equipment to clamp the blank roller 2 on the chuck 4 and ensure that it has the same coaxiality with the chuck 4. The process of adjusting the coaxiality of the blank roller 2 and the chuck 4 is difficult to operate and time-consuming, resulting in low processing efficiency. In addition, the position for clamping the blank roller 2 is limited. If the blank roller 2 is clamped without being pre-positioned, it will cause the clamping to be loose, and there is a risk of the blank roller 2 falling off when the machine tool rotates.
