Description

Technical Field

[0001] This utility model belongs to the technical field of tail-end devices for hobbing, and specifically relates to a tail-end device for hobbing. Background Technology

[0002] The tailstock device for hobbing is a crucial component on hobbing equipment used to support the workpiece shaft end. Its core function is to form a two-end support structure with the fixture at the spindle end, ensuring the workpiece remains stable during hobbing. This device typically includes a tailstock body, a center, an axial adjustment mechanism, and a locking assembly. The center often uses a Morse taper to cooperate with the tailstock spindle and can be precisely positioned according to the workpiece length through the axial adjustment mechanism. After being fixed by the locking assembly, it can effectively counteract workpiece deformation and vibration caused by cutting forces. It is especially suitable for machining long-shaft gear parts, ensuring tooth profile accuracy and surface quality. Some tailstock devices are also equipped with axial thrust bearings or elastic compensation structures to adapt to the force requirements under different machining conditions, improving the reliability and stability of the equipment.

[0003] Generally, tailstock devices are directly fixed to the linear axis of the machine tool. The linear movement of the tailstock is achieved by changing the installation position of the tailstock and the linear axis of the machine tool. This method of manually adjusting the installation position cannot accurately control the displacement of the tailstock device, and multiple installations and adjustments are required to match it with the cutting tool. The efficiency and accuracy are both low, which cannot meet the current market demand. Utility Model Content

[0004] The purpose of this utility model is to provide a tailstock device for hobbing, in order to solve the problems mentioned in the background art. Generally, the tailstock device is directly fixed on the linear axis of the machine tool, and the linear movement of the tailstock is achieved by changing the installation position of the tailstock and the linear axis of the machine tool. This method of manually adjusting the installation position cannot accurately control the displacement of the tailstock device, and multiple installation and adjustment are required to match the tool. The efficiency and accuracy are both low, which cannot meet the current market demand.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tailstock device for hobbing, comprising a base, a guide rail body installed on the upper end of the base at the left and right sides, a plurality of oil inlet holes distributed at the upper end of the guide rail body, the oil inlet holes leading to an oil storage tank located inside the guide rail body, oil outlet holes provided at the left and right ends of the oil storage tank, a sponge placed inside the oil storage tank, a slider body installed on the outer wall of the guide rail body, a slider fixing plate installed at the upper end of the slider body, a pin adjusting block installed at the upper end of the slider fixing plate, a pin mounting block installed at the upper end of the pin adjusting block, a pin body provided at the front end of the pin mounting block, a self-aligning adapter installed at the rear end of the pin adjusting block, a cylinder body provided at the rear end of the self-aligning adapter, and the cylinder body being fixed by a cylinder fixing seat at the front end.

[0006] Preferably, the base is equipped with guide rail blocks at the four upper corners, and the slider body is located at the upper end of the guide rail blocks.

[0007] Preferably, slider side plates are installed at both ends of the slider fixing plate, and the slider side plates are installed to the slider fixing plate by bolts.

[0008] Preferably, the cylinder mounting bracket is installed at the upper end of the base, and the cylinder mounting bracket is installed to the cylinder body by bolts.

[0009] Preferably, the slider fixing plate is installed on the slider body and the ejector pin adjusting block respectively, and the cylinder body pushes the ejector pin adjusting block to move.

[0010] Preferably, the ejector pin adjusting block is pushed, causing the slider body to move along the guide rail body.

[0011] Preferably, the movement of the ejector pin adjusting block causes the ejector pin body and ejector pin mounting block at the upper position to move.

[0012] Preferably, the oil outlet holes are evenly distributed at the left and right ends of the guide rail body, and the sponge is located inside the oil storage tank and the oil outlet holes.

[0013] Compared with the prior art, the present invention provides a tailstock device for hobbing, which has the following advantages:

[0014] With the adoption of a pneumatic tailstock device, when changing to different specifications of cutting tools, there is no need for the tedious and repetitive disassembly and installation of the tailstock as with traditional devices. The machine tool can directly and precisely control the tailstock device, using the gas state of the cylinder controlled by the machine tool to drive the reciprocating motion of the cylinder piston, which in turn drives the self-centering adapter and the ejector pin adjustment block to move linearly in the horizontal direction. This automated control mode greatly reduces the degree of manual intervention, effectively avoiding operational errors caused by manual adjustment, and simplifies the traditional complex control process of the tailstock. In actual operation, only the horizontal pneumatic adjustment is completed by the machine tool, and then the vertical position adjustment of the ejector pin mounting block is performed manually to achieve precise clamping of the workpiece. This not only significantly improves the accuracy and consistency of workpiece clamping, but also greatly shortens the equipment debugging time, allowing the machine tool to be put into the processing process more efficiently, effectively improving the overall processing efficiency of the machine tool, and fully meeting the needs of modern manufacturing industry for high-precision and high-efficiency production.

[0015] This device has an oil inlet at the upper end of the guide rail. Lubricating oil is added through the oil inlet and enters the oil reservoir. The lubricating oil is then absorbed into the sponge, which is connected to the oil outlet. As the slider passes through, the lubricating oil is applied to the inner wall of the slider, making the slider move more smoothly. Attached Figure Description

The movement of the ejector pin adjusting block 4 drives the ejector pin body 5 and ejector pin mounting block 6 at the upper end to move. The oil outlet holes 15 are evenly distributed at the left and right ends of the guide rail body 2. The sponge 14 is located inside the oil storage tank 16 and the oil outlet holes 15.
