Description

Technical Field

[0001] The utility model relates to the technical field of tungsten steel coated round nose knives, in particular to a tungsten steel coated round nose knife installation structure. Background Art

[0002] Tungsten steel coated round nose knife is a kind of tool with tungsten steel coating. The length of the arc part of the tungsten steel coated round nose knife is greater than 1 / 4 circle. Tungsten steel coated round nose knife can be used for rough processing, plane polishing knife and curve contour polishing knife.

[0003] The installation part of the tungsten steel coated round nose knife is a cylindrical structure. Most of the tungsten steel coated round nose knives are installed through an elastic collet. A threaded sleeve is set on the outside of the elastic collet. During installation, the threaded sleeve is rotated to adjust the tightness of the collet.

[0004] Nowadays, the clamping part and the barrel part of most tungsten steel coated round nose knives are integrated. Although they have a certain degree of elasticity, they will bend and deform every time they are used, which may easily lead to breakage after long-term use. In addition, the threaded sleeve does not have a positioning function and may rotate when it comes into contact with foreign objects, thereby reducing the clamping force of the tungsten steel coated round nose knife and failing to improve stability.

[0027] In this embodiment: when in use, the clamping seat 2 is docked with the processing equipment, and the blocking piece 1 prevents the other side component from contacting the processing equipment.

[0028] See also Figure 4 Three clamping plates 4 are arranged in a ring shape about the center line of the outer sleeve 3 , and two guide rods 6 are arranged on the outer sides of the clamping plates 4 .

[0029] In this embodiment, the guide rod 6 guides the clamping plates 4 , and the clamping plates 4 move along the inside of the outer sleeve 3 . The tungsten steel coated round nose knife is placed between the three clamping plates 4 .

[0030] See also Figure 1 The clamping plate 4 is an arc-shaped structure, and the spring 8 is fixedly connected to the outer side of the outer sleeve 3.

[0031] In this embodiment, when there is no external force, the spring 8 applies an outward elastic force to the fixing plate 7, and the clamping plate 4 moves with the fixing plate 7.

[0032] Working principle: Place the tungsten steel coated round nose knife between the three clamping plates 4, move the sliding sleeve 13 to separate the clamping block 16 from the clamping slot 15, then rotate the rotating drum 12, drive the guide block 10 to slide along the sliding slot 11 through the thread, and the inner sleeve 9 moves toward the positioning seat 5 with the guide block 10, and the inner sleeve 9 moves along the inclined surface of the positioning seat 5.

The sliding sleeve 13 applies elastic force, and the block 16 engages with the nearest slot 15 to position the rotating drum 12, preventing the rotating drum 12 from rotating and improving the stability of the installation. The rotating drum 12 is rotated in the same way to separate the inner sleeve 9 from the positioning seat 5. The spring 18 applies an outward elastic force to the fixed plate 7, and the splint 4 moves outward with the fixed plate 7. After that, the tungsten steel coated round nose knife can be directly taken out, and the splint 4 will not slide, which is convenient for the subsequent installation of the tungsten steel coated round nose knife. It is very convenient to use.
