Problems solved by technology
[0002] When the crankshaft is processed, both ends are supported by the top. The top of the existing headstock at one end cannot automatically adjust its position in the axial direction according to the axial force, forming a rigid support. The support method is single, and it cannot be accurately clamped when the crankshaft is clamped. Identify the length of the crankshaft, which brings inconvenience to coaxial machining

Embodiment Construction
[0024] Such as figure 1 , 2 Shown: 12 is main shaft box, and main shaft 11 is supported by bearing in main shaft box 12, and pull bar 10 is arranged in main shaft 11, and chuck 8 is equipped with at main shaft end, is equipped with jaw 4 with chuck 8. The top seat 3 is fixed inside the front of the chuck 8. 1 is the top, the rear of the top 1 is inserted into the inner hole of the top seat 3 and the top spring 5 is installed, the spring 5 is located in the rear center hole of the top 1, the top spring 5 One end leans against the top 1, and the other end leans against the adjustment pad 6 at the bottom of the inner hole of the top seat 3. There is a gap 14 between the tip 1 and the adjusting pad 6 . The front part of the tip 1 is fitted with a guide sleeve 2, and the cross section of the guide sleeve 2 and the tip 1 is triangular, square or polygonal to control the rotation of the tip. The guide sleeve 20 is fixedly connected with the top seat 3 by bolts. The gap 14 communi...

The invention discloses a top device for automatically locating a crankshaft in an axial direction. The top device comprises a main shaft box, a main shaft, a draw bar, a chuck and a top, wherein a top seat is fixed in the chuck; the back of the top is inserted to a hole of the top seat and is provided with a top spring; one end of the top spring props against the top and the other end props against a regulating cushion at the bottom of the hole of the top seat; a gap is remained between the top and the regulating cushion; a guide sleeve is sleeved in the front of the top; the guide sleeve is fixedly connected with the top seat; the gap is communicated with an oil hole in the centre of the draw bar; the oil hole of the draw bar is communicated with a cylinder detection device by a rotary joint; and a sensing element is adapted with the cylinder detection device. The top device is simple in structure, convenient in operation, stable, reliable and strong in flexibility. When the crankshaft is clamped, the axial and radial regulation and location can be achieved.
Description
technical field [0001] The invention relates to a tip device, in particular to a crankshaft axial automatic positioning tip device. Background technique [0002] When the crankshaft is processed, both ends are supported by the top. The top of the existing headstock at one end cannot automatically adjust its position in the axial direction according to the axial force, forming a rigid support. The support method is single, and it cannot be accurately clamped when the crankshaft is clamped. Identifying the length of the crankshaft brings inconvenience to coaxial machining. Contents of the invention [0003] The purpose of the present invention is to provide a crankshaft axial automatic positioning tip device which can automatically position the crankshaft axially, cooperate with the chuck to automatically radially position, and can automatically identify the length of the crankshaft when clamping, has a simple structure, and is flexible and reliable in action. Insufficiency...
