Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and relates to a CNC machine tool, and particularly to a novel CNC machine tool. Background Technology

[0002] A machine tool is a device that primarily uses a cutting tool to machine rotating workpieces. A machine tool mainly consists of support components, a speed change mechanism, a feed mechanism, a spindle box, a lubrication system, and a tailstock. Modern mechanical manufacturing employs many methods for machining mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, and extrusion. However, parts requiring high precision and fine surface roughness generally require final machining on a machine tool using cutting methods. Machine tools play a significant role in the modernization of the national economy. They are mainly composed of lathes, milling machines, drilling machines, and other machining equipment forming a complete equipment system. CNC machine tools often use a tailstock to assist in fixing the workpiece during machining.

[0003] The existing ejector tailstock cannot conveniently adjust the actual working height and position of the ejector tailstock according to the actual situation, thus it cannot provide convenient and stable auxiliary fixing for different workpieces, thereby failing to guarantee the stability and convenience of subsequent CNC processing of the workpiece, resulting in poor applicability. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel CNC machine tool that is highly adjustable.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel CNC machine tool, comprising a machine tool body and an ejector tailstock disposed on the machine tool body, characterized in that the ejector tailstock comprises a lower base, an upper base and an ejector body, an adjusting device for adjusting height is disposed between the lower base and the upper base, a lower mounting groove and an upper mounting groove for mounting the adjusting device are respectively provided on the lower base and the upper base, the adjusting device comprises an adjusting body, a plunger and a hydraulic cylinder, a partition layer is disposed at the inner diameter of the plunger, a liquid inlet is disposed on the partition layer, a one-way valve is disposed between the plunger and the hydraulic cylinder, and the one-way valve is disposed at the liquid inlet, and an oil inlet groove is disposed on the adjusting body relative to the contact point with the plunger.

[0006] In the aforementioned novel CNC machine tool, the adjusting body is provided with an oil inlet hole one, the lower base is provided with an oil inlet hole two that communicates with the oil inlet hole one, and a sealing plug is provided on the oil inlet hole two.

[0007] In the aforementioned novel CNC machine tool, the adjusting body abuts against the lower mounting groove, and the hydraulic cylinder abuts against the upper mounting groove.

[0008] In the aforementioned novel CNC machine tool, the lower base is provided with several limiting posts, and the upper base is provided with several limiting holes that cooperate with the limiting posts.

[0009] In the aforementioned novel CNC machine tool, a limit snap ring is provided on the hydraulic cylinder.

[0010] Compared with the prior art, this utility model injects oil into the adjustment device in the mounting groove through the oil inlet hole. After the oil enters the adjustment body, it enters the space between the plunger and the adjustment body through the oil inlet groove. The oil squeezes the one-way valve at the inlet and enters the hydraulic cylinder, causing the hydraulic cylinder to move upward, thereby moving the upper base upward. This makes the position adjustment of the ejector pin tailstock convenient and does not require fixing. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1As shown, this novel CNC machine tool includes a machine tool body 1 and an ejector tailstock 2 disposed on the machine tool body 1. The ejector tailstock 2 includes a lower base 3, an upper base 4, and an ejector body 5. An adjustment device 6 for adjusting height is disposed between the lower base 3 and the upper base 4. The lower base 3 and the upper base 4 are respectively provided with a lower mounting groove 7 and an upper mounting groove 8 for installing the adjustment device 6. The adjustment device 6 includes an adjustment body 9, a plunger 10, and a hydraulic cylinder 11. A partition layer 12 is disposed at the inner diameter of the plunger 10. A liquid inlet 13 is disposed on the partition layer 12. A one-way valve 14 is disposed between the plunger 10 and the hydraulic cylinder 11, and the one-way valve 14 is disposed at the liquid inlet 13. An oil inlet groove 15 is disposed on the adjustment body 9 relative to the contact point with the plunger 10.

[0016] To elaborate further, the regulating body 9 has an oil inlet hole 16, and the lower base 3 has an oil inlet hole 2 17 that communicates with the oil inlet hole 16. A sealing plug 18 is provided on the oil inlet hole 2 17.

[0017] To elaborate further, the adjusting body 9 abuts against the lower mounting groove 7, and the hydraulic cylinder 11 abuts against the upper mounting groove 8.

[0018] To elaborate further, the lower base 3 is provided with several limiting posts 19, and the upper base 4 is provided with several limiting holes 20 that cooperate with the limiting posts 19 to prevent displacement.

[0019] To elaborate further, a limit snap ring 21 is provided on the hydraulic cylinder 11.

[0020] Working principle: Oil is injected into the adjusting device 6 in the mounting groove through the oil inlet. After the oil enters the adjusting body 9, it enters the space between the plunger 10 and the adjusting body 9 through the oil inlet groove 15. The oil squeezes the one-way valve 14 from the inlet 13 and enters the hydraulic cylinder 11, causing the hydraulic cylinder 11 to move upward, thereby moving the upper base 4 upward. This makes the position adjustment of the ejector pin tail seat 2 convenient and does not require fixing.
