Accompanying drawing 2 is the structure diagram of another embodiment of the tip introducing device of the present invention.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Embodiment 1: with reference to accompanying drawing 1. A tip introduction device for turning, including a Morse tip 6, a center fixing sleeve 2, a shaft head introduction sleeve 1, a sliding plate 4, and a pressure spring 5; the Morse tip 6 is a prior art, and will not be described here; the center is fixed The sleeve 2 is set at the front end of the top 6 and is set on the outer wall of the top 6. The rear end of the central fixing sleeve 2 is connected and fixed with the outer round end of the top 6 by three screws 3, and the three screws 3 are arranged in a ring and evenly distributed on the central fixing sleeve 2. In the radial direction, that is, the angle between the three screws 3 is 120 degrees; a cavity 7 is formed in the middle of the center fixing sleeve 2, and the sliding plate 4 and the spring 5 are all arranged in the cavity 7 of the center fixing sleeve 2, and the front end of the center fixing sleeve 2 The surface is a circular platform 9, which limits the sliding plate 4 and the spring 5 in the cavity 7 of the central fixed sleeve 2; the sliding plate 4 can slide in the inner cavity 7 of the central fixed sleeve 2; the spring 5 is sleeved on the At the tip of the tip 6, the sliding plate 4 is arranged at the front of the spring 5, that is, the spring 5 is arranged between the sliding plate 4 and the tip 6; The sliding plate 4 is flush, and the shoulder 10 of the introduction sleeve 1 is fixedly connected with the sliding plate 4 by screws; the center of the introduction sleeve 1 is provided with a clamping hole 8, and the front end of the introduction sleeve 1 protrudes from the center fixing sleeve 2, and the clamping hole 8 It is a counterbore, and the counterbore end of the introduction sleeve 1 is located at the front end of the introduction sleeve 1; during operation, the shaft head at the tail end of the workpiece is directly inserted into the clamping hole 8 of the introduction sleeve 1, and it can be automatically aligned with the top 6 when it is inserted.
