Description

Technical Field

[0001] The invention belongs to the technical field of machine tool processing, and in particular relates to a small-sized simple double-station spiral bevel gear processing device. Background Art

[0002] Existing spiral bevel gear milling machines or gear grinding machines are mainly divided into single-station and double-station. The motion axes of existing single-station spiral bevel gear milling machines or gear grinding machines are A-axis (spindle that drives the workpiece to rotate), B-axis (deflection axis that drives the workpiece spindle to rotate along the fixed axis), C-axis (spindle that drives the tool to rotate), X-axis (linear axis that drives the workpiece spindle to move forward and backward), Y (linear axis that drives the workpiece spindle to move up and down), and Z-axis (linear axis that drives the tool spindle to move forward and backward). There are six axes in total. The double-station spiral bevel gear milling machine has a similar structure to the above-mentioned single-station spiral bevel gear milling machine, except that two single-station spiral bevel gear milling machines are integrated together, and the number of the six motion axes A / B / C / X / Y / Z is changed from one to two; there are two sets of machine tool spindles, A1 / B1 / C1 / X1 / Y1 / Z1 and A2 / B2 / C2 / X2 / Y2 / Z2. The two groups of spindles operate independently of each other and can clamp two workpieces at a time. A1 / B1 / C1 / X1 / Y1 / Z1 is used to process the first workpiece, and A2 / B2 / C2 / X2 / Y2 / Z2 is used to process the second workpiece.

[0003] For example, the invention patent with publication number CN107175372B discloses a spiral bevel gear double-station milling machine tool, which combines the above-mentioned Y1 and Y2 axes into one, and the Z1 and Z2 axes into one, thereby optimizing the volume structure of the machine tool, saving the floor space of the machine tool, improving the utilization rate of space, and saving costs. It has two sets of tool spindles, two sets of workpiece spindles and related deflection axes, etc. Although two workpieces can be processed at the same time, the equipment still has a large ground area and a high manufacturing cost. Summary of the invention

[0004] The purpose of the present invention is to provide a small and simple double-station spiral bevel gear processing equipment, aiming to achieve double-station processing while optimizing the volume of the processing equipment.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a small and simple double-station spiral bevel gear processing device, comprising:

[0007] A base and a first workbench and a second workbench fixedly arranged on the base; the cross section of the first workbench is L-shaped, a first guide rail along the vertical direction is fixedly arranged on one outer side of the first workbench, and a second guide rail along the horizontal direction is fixedly arranged on the other adjacent outer side;

[0008] A first sliding block slidably connected to the first guide rail is arranged on the first guide rail, a first mounting seat slidably connected to the first sliding block is arranged on the first sliding block, and a tool spindle is fixedly arranged on the first mounting seat;

[0009] The second guide rail is provided with a second slider slidably connected thereto, the second slider is fixedly provided with a second mounting seat, and the second mounting seat is provided with a first workpiece spindle rotatably connected thereto;

[0010] A third guide rail along the horizontal direction is fixedly arranged on an outer side surface of the second workbench, a third slider slidably connected thereto is arranged on the third guide rail, a third mounting seat is fixedly arranged on the third slider, and a second workpiece spindle rotatably connected thereto is arranged on the third mounting seat.

[0012] Advantages of the present invention:

[0013] Compared with a single-station spiral bevel gear milling machine, the small-sized and simple double-station spiral bevel gear processing equipment provided by the present invention has a small size and high processing efficiency, and can significantly improve production efficiency and reduce production costs in mass production.

[0014] Compared with the existing double-station gear milling machine, the present invention reduces the original two tool spindles C1 and C2 to one tool spindle, and the tool on one tool spindle processes the workpieces on two workpiece spindles at the same time. It can greatly reduce the equipment manufacturing cost (the cost of a single tool spindle is about 800,000 to 1.5 million yuan) and reduce the equipment footprint. BRIEF DESCRIPTION OF THE DRAWINGS
