Description

Technical Field

[0001] This utility model relates to the field of drive shaft technology, specifically to an improved spindle for long life of ultra-precision machines. Background Technology

[0002] Machine tools require the use of a drive spindle. During use, testing, or prolonged use, wear on one side of the spindle can lead to a reduction in mass on that side. This can cause the spindle to rotate unstablely, generating high-frequency vibrations. Consequently, the spindle may malfunction or experience severe friction during use, significantly reducing its lifespan. Therefore, a long-life improved spindle for ultra-precision machines is needed to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide an improved spindle for long life of ultra-precision machines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved spindle for long life of an ultra-precision machine, comprising a first adjustment part, a spindle, a second adjustment part, and a mounting groove. The mounting groove is evenly disposed on the inner sides of both ends of the spindle. The first adjustment part and the second adjustment part are disposed inside both ends of the spindle through the mounting groove, and the first adjustment part and the second adjustment part have the same structure.

[0005] Preferably, both the first and second adjustment parts include a sliding groove, a lifting adjustment plate, a fixing bolt, a limiting column, a fixed base, a locking threaded column, and a side fixing plate. The limiting column is fixedly connected to the upper middle part of the fixed base. The sliding groove is opened through the middle part of the limiting column. The lifting adjustment plate is slidably engaged with the limiting column through the sliding groove. The side fixing plate is fixedly connected to both sides of the lifting adjustment plate. The locking threaded column is symmetrically threaded and rotatably inserted into the side fixing plate. The fixing bolt is uniformly threaded and rotatably inserted into the fixed base.

[0006] Preferably, the upper ends of both sides of the lifting and adjusting plate are fixedly connected to supporting columns.

[0007] Preferably, a counterweight adjustment ball is fixedly installed at the upper middle part of the support column.

[0008] Preferably, the fixing base is fixedly installed inside the mounting groove by the fixing bolts.

[0009] Preferably, the side end of the limiting column is provided with a scale line, and the upper end surface of the lifting adjustment plate is aligned with the scale line.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] When a mass deviation occurs on one side of the spindle at both ends, the present invention calibrates and adjusts the mass deviation at the ends of the spindle by means of a first or second adjustment part evenly distributed at both ends of the spindle. By screwing the locking threaded column to release the squeezing force on the outer wall of the limiting column, the side fixing plate can drive the support column and the counterweight adjustment ball to slide along the limiting column for adjustment. Furthermore, under the action of the scale line set on the side of the limiting column, precise position adjustment can be achieved. The adjusted support column and counterweight adjustment ball can prevent high-frequency rotation or severe friction due to one side being heavier or lighter during the rotation of the spindle, allowing the spindle to be used stably and safely for a long time. In addition, four first and second adjustment parts are respectively set at both ends of the spindle for adjustment, which can fully ensure the stable rotation of the spindle during the rotation process.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of an improved long-life spindle for an ultra-precision machine, comprising a first adjustment part 1, a spindle 2, a second adjustment part 3, and a mounting groove 4. The mounting groove 4 is evenly disposed on the inner sides of both ends of the spindle 2. The first adjustment part 1 and the second adjustment part 3 are disposed inside both ends of the spindle 2 through the mounting groove 4, and the first adjustment part 1 and the second adjustment part 3 have the same structure.

[0018] Both the first adjustment part 1 and the second adjustment part 3 include a sliding slot 7, a lifting adjustment plate 8, a fixing bolt 9, a limiting column 10, a fixed base 11, a locking threaded column 12, and a side fixing plate 13. The limiting column 10 is fixedly connected to the upper middle part of the fixed base 11. The sliding slot 7 is opened through the middle part of the limiting column 10. The lifting adjustment plate 8 is slidably engaged with the limiting column 10 through the sliding slot 7. The side fixing plate 13 is fixedly connected to both sides of the lifting adjustment plate 8. The locking threaded column 12 is symmetrically threaded and rotated into the side fixing plate 13. The fixing bolt 9 is evenly threaded and rotated into the fixed base 11.

[0019] The upper ends of both sides of the lifting and adjusting plate 8 are fixedly connected to the support columns 6, and the upper middle part of the support columns 6 is fixedly installed with the counterweight adjusting ball 5, which can fully realize calibration and adjustment.

[0020] The fixed base 11 is fixedly installed inside the mounting groove 4 by fixing bolts 9.

[0021] The limit column 10 has a scale line on its side, and the upper surface of the lifting adjustment plate 8 is aligned with the scale line to achieve precise distance adjustment.

[0022] Working principle: When calibrating or inspecting the spindle 2, if there is a mass deviation on one side of both ends of the spindle 2, the first adjustment part 1 or the second adjustment part 3, which are evenly distributed at both ends of the spindle 2, are used to calibrate and adjust the mass deviation at the ends of the spindle 2. By turning the locking threaded column 12, the squeezing force on the outer wall of the limiting column 10 is released, which allows the side fixing plate 13 to drive the support column 6 and the counterweight adjusting ball 5 to slide along the limiting column 10. Under the action of the scale line set on the side of the limiting column 10, the position can be adjusted accurately. After adjustment, the support column 6 and the counterweight adjusting ball 5 can prevent high-frequency rotation or severe friction due to one side being heavier or lighter during the rotation of both ends of the spindle 2, so that the spindle 2 can be used stably and safely for a long time.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
