Embodiment approach 1

[0050] This solution is used for large gear sizes, or when the spindle structure directly driven by a high-torque servo motor is relatively expensive in price, and the local area does not have the technology to completely independently manufacture and install such a spindle structure. However, countries and regions with relatively rich technical resources in general machinery manufacturing. There, there are gear manufacturers who are not rich in funds and want to purchase equipment that can use both the efficient "dry cutting method" and the traditional "wet cutting method", and can use the "continuous indexing method" or the "intermittent indexing method". Bevel gear processing machine tools.

[0051] Such as Figure 13 , Figure 14 , Figure 15 , Figure 16 As shown, on a complete bed S, the machine tool has a column 1 whose upper surface of the bottom plate is inclined greater than 25° to 35° and another column 2 with a horizontal bottom surface. The column 1 uses a gu...

Embodiment approach 2

[0057] In this embodiment, the gear spindle A, the pivot shaft 113 in the axial direction of the rotating tool spindle, and the tool spindle C itself, which drives the tool to rotate, are all directly driven by a high-torque servo motor to complete all the corresponding three steps in Embodiment 1. a rotary motion. Such as Figure 17 As shown, after all are directly driven by high-torque servo motors, the tool headstock 10 and the pivot 113 will form a group of simple cantilever structures on the column 1 . The pivot 113 installed directly in the column 1 will be as Figure 18 , Figure 19 , Figure 20 Driven by a high torque servo motor 120 as shown. And according to the command of the control system, the tool headstock 10 rotates around the axis B of the pivot 113 during the non-cutting period and the cutting (or grinding) period, and the micro swing less than 3 and a half degrees.

[0058] All the other features of this embodiment are identical to Embodiment 1.

Embodiment approach 3

[0060] This implementation plan deliberately strengthens the Figure 17 , Figure 21 , Figure 22 and Figure 23 The support strength of the column 1 to the tool headstock 10 is shown. Such as Figure 18 , Figure 19 , Figure 20As shown, this solution is provided with a structure 12 at the rear end of the headstock 10 . The structure 12 is composed of two sectors 114 coaxial with the axis B of the pivot 113 . Arc grooves are formed on the inner arc edges of the sector blocks 114 . The flange 115 of the fan-shaped plate fixedly installed on the column 1 is sleeved in the arc groove. There are three or more mutually symmetrical miniature oil cylinders 117 and pistons 119 on both sides of the arc groove 114 . Pressure oil enters the oil cylinder 117 through the oil hole 116 . Under the thrust of the oil pressure, the pistons 119 are pressed to the respective corresponding rollers 118 from both sides. Make the corresponding rollers 118 on both sides of the flange of th...

Abstract

The invention discloses a multi-spindle free type numerically controlled spiral bevel gear and skew gear machine tool. The tool body is equipped with a post 1 which performs rectilinear motion along a horizontal linear guide rail at the Y direction and a post 2 which performs the rectilinear motion along a horizontal linear guide rail at the horizontal direction vertical to the Y direction. The post 1 is used for supporting a pivot 113. An axis B of the pivot 113 is arranged in a horizontal plane. A tool main spindle box 10 for mounting a tool spindle is fixedly connected on the pivot. The tool main spindle box 10 can rotate around a horizontal pivot axis B which is vertically intersected with a tool main spindle axis C. The post 2 is used for supporting a gear main spindle box 20, and a gear main spindle for mounting a gear rotates around an axis A in the gear main spindle box 20. The gear main spindle box 20 can perform linear elevation at the vertical direction on the post 2. The machine tool can effectively lower center of gravity of the whole machine tool and improve natural vibration frequency of vibration resistance performance of system; and the machine tool causes the numerical control and mechanical system to easily and stably complete the operating process of machining gears in the high-precision state.

Description

technical field [0001] The invention belongs to the field of milling and grinding machines for spiral bevel and hypoid gears in machines for the manufacture of gears. Background of the invention [0002] Modern research and development of free-type CNC spiral bevel gear and hypoid gear processing machine tools with six spatial degrees of freedom, although it can implement the dry cutting method to process gears to improve processing efficiency, the processing quality has also improved. However, the production practice shows that these machine tools are still difficult to achieve the predetermined tooth surface quality and the high production efficiency index that the dry cutting method should have. Their problems are concentrated in (1) the cutting tool cannot reach the expected regrinding life; (2) the machine tool provided by the existing patent is difficult to achieve the predetermined production efficiency in practical application; (3) the tooth surface is processed some...
