Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and in particular relates to a pipe sleeve chamfering device. Background Art

[0002] During the machining process, it is often necessary to chamfer the inner sides of the ports on both sides of the pipe sleeve to remove burrs on the inner side of the pipe sleeve ports and to facilitate the connection of the pipe sleeve with other components, reducing the difficulty and time of installation. Currently, the chamfering of the inner corners of the pipe sleeve ports is mainly done by manually operating a machine tool. That is, after the pipe sleeve is fixed to the machine tool workbench with a clamp, one side of the pipe sleeve is chamfered. After the chamfering is completed, the pipe sleeve needs to be removed from the clamp, turned over and re-clamped on the other side, and then the inner corners of the other side of the pipe sleeve are chamfered. This processing method results in a pipe sleeve needing to be clamped twice, which not only reduces the processing efficiency but also increases the labor intensity of the operator.

[0035] The working principle of this utility model is as follows:

[0036] See also Figure 6 As shown in the figure (label A in the figure represents this device; label B in the figure represents the sleeve), before chamfering the sleeve, first clamp the chamfering tool 239 to the chuck 238, and then install the corresponding support plate 222 to the support plate cylinder 221; then adjust the installation position of the first magnetic switch 224 and the second magnetic switch 241.

[0037] When the sleeve needs to be chamfered, the device is started. At this time, the motor 234 drives the chamfering tool 239 to rotate; then the sleeve is placed on the support plate 222. At this time, the inner hole of the lower end of the sleeve is sleeved on the positioning pin 2221, and the axial center line of the sleeve basically coincides with the chamfering tool 239. After the placement is completed, the support plate cylinder 221 lifts the sleeve to the set height through the support plate 222, and after it is lifted into place, the clamping cylinder 35 drives the clamping plate 36 to clamp the sleeve, and the lifting cylinder 240 drives the chamfering tool 239 to move downward to achieve chamfering on one end of the sleeve; when the chamfering on one side is completed, the lifting cylinder 240 drives the chamfering tool 239 to move upward and reset, while the support plate cylinder 221 drives the support plate 222 to move downward and reset, and After the pin 2221 is disengaged from the inner hole of the sleeve, the driving assembly 33 drives the clamping cylinder 35 to rotate 180° through the rotating shaft 32, thereby inverting the upper and lower ends of the sleeve. After the rotation is completed, the support cylinder 221 drives the support plate 222 to rise to the set height again. At this time, the positioning pin 2221 is inserted into the inner hole of the sleeve, and the upper end surface of the support plate 222 contacts the sleeve. Then, the lifting cylinder 240 drives the chamfering tool 239 to move downward to chamfer the other end of the sleeve. After the chamfering is completed, the lifting cylinder 240 drives the chamfering tool 239 to move upward and reset. At the same time, the clamping cylinder 35 drives the clamping plate 36 to release the clamping of the sleeve. After it is completely released, the support cylinder 221 drives the sleeve to descend and reset through the support plate 222, completing a set of sleeve chamfering.

[0038] It should be noted that, during the processing, when the specifications and dimensions of the sleeve remain unchanged, due to the change in the length of the chamfering tool 229, the installation position of the second magnetic switch 241 needs to be adjusted to ensure the consistency of the sleeve chamfer; or, when the length of the chamfering tool 229 remains unchanged, due to the change in the specifications and dimensions of the sleeve, the installation positions of the first magnetic switch 224 and the second magnetic switch 241 need to be adjusted accordingly.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
