Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The spindle shaft 10 shown in fig. 1 mainly includes a main body 110, a connecting portion provided at one end of the main body 110, and a shoulder 130 provided at the other end of the main body 110. The connecting portion has a first mounting surface 121 and a second mounting surface 122 which are oppositely arranged, and the first mounting surface 121 and the second mounting surface 122 are parallel. Generally, the machining method of the spindle 10 is as follows: firstly, a lathe is adopted to carry out rough machining on the blank, and then a CNC machine tool is adopted to carry out finish machining on the spindle shaft 10. The machining tool for the spindle of the present embodiment mainly solves the problem of fast and accurate positioning of the spindle 10 on the CNC, and is installed on a jaw of the CNC machine tool for clamping the spindle 10.

As shown in fig. 2 to 5, the machining tool for a spindle of a spindle machine according to the present embodiment mainly includes a first clamping block 1, a second clamping block 2, and a positioning member 3. The first clamping block 1 is used for being installed on a jaw of a CNC machine tool and comprises a first wall surface 11 and a second wall surface 12 which are vertically connected, wherein the first wall surface 11 is provided with a first groove 13, and the first groove 13 extends along a direction perpendicular to the second wall surface 12. The second clamping block 2 has a third wall surface 21 for abutting against the first wall surface 11 of the first clamping block 1, and a second groove 22 is provided on the third wall surface 21. When the second clamping block 2 is connected with the first clamping block 1 and the first wall surface 11 abuts against the third wall surface 21, the first groove 13 and the second groove 22 can form a cylindrical cavity, and the diameter (or the inner diameter) of the cylindrical cavity is the same as that of the main body 110 of the spindle 10, so that the spindle 10 can be fastened in the cavity by the first clamping block 1 and the second clamping block 2. The positioning element 3 is detachably mounted on the second wall surface 12 of the first clamping block 1, the positioning element 3 is provided with a fourth wall surface 31 which is used for abutting against the first mounting surface 121 or the second mounting surface 122 of the centering machine shaft 10, and when the positioning element 3 is mounted on the second wall surface 12 of the first clamping block 1, the fourth wall surface 31 is always parallel to the first wall surface 11, so that the centering machine shaft 10 to be processed can be mounted on a tooling at a preset angle and a preset position all the time, that is, the centering machine shaft 10 to be processed can be mounted on a CNC machine tool at a preset angle and a preset position all the time.

By the structure, the use method of the machining tool for the spindle of the center-moving machine in the embodiment comprises the following steps: installing the first clamping block 1 on a vice of a CNC machine tool; the spindle 10 penetrates into the first groove 13, and the first mounting surface 121 and the second mounting surface 122 of the connecting part extend out of the first groove 13; positioning the spindle 10 by using the positioning member 3, specifically, making the fourth wall surface 31 of the positioning member 3 parallel and abut against the first mounting surface 121 or the second mounting surface 122 of the spindle 10; fastening the second clamping block 2 to the first clamping block 1 such that the second groove 22 and the first groove 13 together clamp the main body 110 of the spindle 10; after the main body 110 is clamped, the positioning member 3 is detached from the second wall surface 12 of the first clamping block 1, so as to prevent the positioning member 3 from affecting the feed of the CNC machine.

By adopting the scheme, when the spindle 10 is clamped, the spindle 10 can be assisted to be quickly positioned in a mode that the fourth wall surface 31 of the positioning piece 3 is abutted against the first mounting surface 121 or the second mounting surface 122 of the spindle 10, so that the first mounting surface 121 and the second mounting surface 122 of the spindle 10 can be arranged on a CNC (computer numerical control) machine tool at preset positions and angles during each clamping, namely, the accuracy of the clamping position of the spindle 10 is ensured.

As shown in fig. 2 and 3, the length of the first recess 13 may be slightly smaller than the length of the main body 110 of the spindle 10 to ensure that the first mounting surface 121 and the second mounting surface 122 of the connecting portion can completely extend out of the first recess 13 while ensuring the clamping stability. When the spindle is required to be installed, one end, provided with the connecting portion, of the spindle 10 can be directly inserted into the first groove 13, the second clamping block 2 is fastened on the first clamping block 1 when the shaft shoulder 130 abuts against the first clamping block 1, therefore, the length of the spindle 10 inserted into the first groove 13 can be a fixed amount, when a worker inserts the spindle 10 into the first groove 13, the fact that the insertion amount is too large or too small does not need to be considered, the shaft shoulder 130 of the spindle 10 is only required to abut against the first clamping block 1, and the efficiency and accuracy of clamping the spindle 10 are further improved.

With continued reference to fig. 2 and 3, on the premise of satisfying the clamping stability, the length of the second groove 22 may be smaller than the length of the first groove 13, so that the processing difficulty of the second clamping block 2 and the second groove 22 may be reduced.

As shown in fig. 4 and 5, the first groove 13 of the present embodiment has a major arc shape in a section parallel to the second wall surface 12, and correspondingly, the second groove 22 has a minor arc shape in a section parallel to the second wall surface 12.

As shown in fig. 2, the second block 2 of the present embodiment may be detachably coupled to the first block 1 by bolts 4.

As shown in fig. 2, the positioning element 3 of the present embodiment can be detachably mounted on the first clamping block 1 through the positioning pins 5 disposed on the first clamping block 1, the number of the positioning pins 5 is greater than or equal to 2, the positioning pins 5 can facilitate the quick mounting and dismounting of the positioning element 3, and the number of the positioning pins 5 cannot be less than 2, so as to avoid the problem that the positioning element 3 rotates when only 1 positioning pin 5 exists, thereby causing the unreliable positioning. Preferably, the number of the positioning pins 5 of this embodiment is 2, which can not only meet the positioning requirement of the positioning member 3, but also avoid the over-positioning phenomenon.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
