Description

TECHNICAL FIELD

[0001] The utility model mainly relates to numerical control lathe processing technical field, concretely relates to a lathe dog positioning abutment. BACKGROUND

[0002] The dog positioning abutment is a device for positioning workpieces clamped by a lathe chuck, and is used to prevent displacement of shaft parts or sheet parts during lathe machining, and to prevent quality, equipment and personnel safety accidents.

[0003] During the specific implementation operation, the inventor found the following defects:

[0004] The original dog positioning abutment is simply a baffle, and there is a gap between the baffle slot and the dog to facilitate placement of the dog inside the dog during use. However, the gap can cause the dog to move between the dogs during actual use, causing noise, and the larger the gap, the louder the noise. In addition, the clamping part is fixed and the clamping part is more, which brings a lot of inconvenience to the operator, and it is easy to be inconsistent with the rotation center of the lathe. If the tail seat center is forced to stop the workpiece center hole, the workpiece will be blocked, causing the tail seat center to also swing. Even for turning of a workpiece with a large diameter, vibration can also occur, which seriously affects the workpiece machining quality and brings a lot of trouble to the operator, resulting in many inconveniences in operation and use.

[0005] It should be noted that the above content belongs to the technical cognition of the inventor. Since the technical content in this field is vast and complex, the above content of the present application does not necessarily constitute the prior art. CONTENT OF THE UTILITY MODEL
