[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

Unless otherwise specified, "plurality" means two or more.

[0038] The existing processing of locomotive wheel hubs generally requires a turning tool with an effective length of more than 300mm, and the commonly used lathe turning tools cannot meet this requirement. In order to solve the problem of insufficient turning tool length, the prior art generally adopts the method of directly lengthening the turning tool body. However, since the turning tool is a consumable, it is generally necessary to replace a new turning tool every once in a while, and the turning tool has a relatively high material cost due to its high hardness requirements. Therefore, if the turning tool is directly lengthened, the use cost of the turning tool will be greatly increased. Moreover, if the turning tool is too long, when the turning tool processing worker When the feed rate is large, the force on the tool head increases, and the tool is prone to vibrate, resulting in a decrease in the machining accuracy of the workpiece. At the same time, due to the high cost of turning tool materials, the tool body should not be processed too thick, otherwise the cost of the turning tool will increase significantly. In this way, the inventor thought of designing a transition piece between the turning tool and the turning tool fixture, that is, the anti-vibration tool rod in the present application. Since the anti-vibration tool rod is not a consumable, the anti-vibration tool rod can be processed relatively thick, and it itself has higher stability than the turning tool fixture. At the same time, the length of the anti-vibration tool rod can make up for the insufficient length of the turning tool.

[0039] In view of this, the present invention provides an anti-trembling tool bar, which is applied to a lathe. The anti-trembling tool bar includes a main body and a connecting part which are integrally formed along its own length direction, and the connecting part has a clamping groove for clamping with the tool clamp of the lathe; an end of the main body away from the connecting part forms a tool clamping groove, which is used to clamp the tool, and the side wall of the tool clamping groove has at least two threaded holes, which are configured to be screwed on by bolts so that the tool in the tool clamping groove can be locked in the tool clamping groove through the end of the bolt. The solution provided by the present invention is to set an anti-trembling tool rod between the lathe tool clamp and the lathe tool. When in use, the lathe tool can be clamped in the tool clamping groove at one end of the anti-trembling tool rod, and the bolt is screwed into the threaded hole on the side wall of the tool clamping groove. The end of the bolt is used to lock and fix the tool in the tool clamping groove, and the anti-trembling tool rod is clamped and fixed to the lathe tool clamp through the clamping groove at the other end thereof. In this way, the anti-trembling tool rod can indirectly increase the machining range of the lathe tool and make up for the insufficient length of the lathe tool. The length of the lathe tool itself does not need to be changed, which can prevent the lathe tool from vibrating during use, improve the machining accuracy of the workpiece, and at the same time reduce the use cost of the lathe tool.

[0040] Figure 1 A partial cross-sectional view of a first anti-trembling knife bar provided in an embodiment of the present invention; Figure 2 for Figure 1 A top view of the anti-tremor blade in FIG. Figure 3 A partial cross-sectional view of a second anti-trembling knife bar provided by an embodiment of the present invention; Figure 4 for Figure 3 Top view of the anti-vibration tool bar in. Figures 1 to 4 An embodiment of the present invention provides an anti-trembling tool rod 100, which can be used on a lathe. The anti-trembling tool rod 100 includes a main body 110 and a connecting portion 120 integrally formed along its own length direction, wherein the connecting portion 120 has a clamping groove 121 for clamping with a turning tool fixture of the lathe; an end of the main body 110 away from the connecting portion 120 can form a tool clamping groove 111, which is used to clamp the turning tool of the lathe, and has at least two threaded holes 112 on the side wall of the tool clamping groove 111, which is configured to be screwed on by a bolt, so that the turning tool in the tool clamping groove 111 is locked in the tool clamping groove 111 through the abutting force of the end of the bolt.

[0041] It should be noted that the lathe tool holder may have a clamping portion that matches the shape of the clamping slot 121 on the connecting portion 120, and the clamping slot 121 on the connecting portion 120 may be clamped into the clamping portion, and the side wall of the tool holder may also have a threaded hole 112. When the connecting portion 120 is clamped with the clamping portion of the tool holder, the connecting portion 120 and the tool holder may be fastened together by passing a bolt through the threaded hole 112, and the specification of the threaded hole 112 may be consistent with the specification of the threaded hole 112 on the anti-trembling tool rod 100. In this way, the bolts on both may be universal, so as to save costs and reduce the installation work of the anti-trembling tool rod 100.

[0042] The solution provided by the embodiment of the present invention is to set an anti-trembling tool rod 100 between the lathe tool clamp and the lathe tool. When in use, the lathe tool can be clamped in the tool clamping groove 111 at one end of the anti-trembling tool rod 100, and the bolt is screwed into the threaded hole 112 on the side wall of the tool clamping groove 111. The end of the bolt is used to tightly fix the tool in the tool clamping groove 111 in the tool clamping groove 111, and the anti-trembling tool rod 100 is clamped and fixed to the tool clamp of the lathe through the clamping groove 121 at the other end thereof. In this way, the anti-trembling tool rod 100 can indirectly increase the processing range of the lathe tool and make up for the insufficient length of the lathe tool. The length of the lathe tool itself does not need to be changed, which can prevent the lathe tool from vibrating during use, improve the processing accuracy of the workpiece, and at the same time, reduce the use cost of the lathe tool.

[0043] In the above embodiment, the notch of the tool clamping groove 111 can extend to the end face of the main body 110 away from the connecting portion 120 . When the turning tool is clamped in the tool clamping groove 111 , the tool head of the turning tool can protrude from the end face of the main body 110 away from the connecting portion 120 .

[0044] like Figure 1 and Figure 2 As shown, in the above embodiment, the tool clamping groove 111 can pass through the opposite sides of the main body 110. When the turning tool is clamped in the tool clamping groove 111, the tool head of the turning tool can protrude from both sides of the main body 110. The cross-section of the tool clamping groove 111 can be rectangular, square or other shapes, and there is no specific restriction here. The length of the tool clamping groove 111 along the main body 110 can be made smaller than the length of the turning tool. In this way, when the turning tool is clamped in the tool clamping groove 111, the part of the turning tool located in the tool clamping groove 111 can abut against the bottom of the tool clamping groove 111, and the tool head part of the turning tool can protrude from the tool clamping groove 111, so that the turning tool can be clamped more firmly in the tool clamping groove 111.

[0045] like Figure 3 and Figure 4As shown, in the above embodiment, the notch of the tool clamping groove 111 can extend along the first direction X to one of the side surfaces of the main body 110, and the tool clamping groove 111 extends along the length direction of the main body 110, and the first direction X is perpendicular to the length direction of the main body 110. In the tool clamping groove 111 of this structure, the tool head of the turning tool generally extends from the end face away from the main body 110, and the length direction of the turning tool, the extension direction of the tool clamping groove 111 and the length direction of the main body 110 are consistent. In this way, most of the blade of the turning tool can be held in the tool clamping groove 111 through the tool clamping groove 111, and due to the tool clamping groove of this structure 111 does not have to penetrate both sides of the main body 110 along the first direction X. The movement of the turning tool can be further restricted by the inner wall of the tool clamping groove 111, so that the turning tool can be clamped more firmly in the tool clamping groove 111. In addition, since the length direction of the turning tool is consistent with that of the tool clamping groove 111, more threaded holes 112 can be opened on the side wall extending along the length direction of the tool clamping groove 111. Specifically, the number of threaded holes 112 can be greater than or equal to three, and these threaded holes 112 are spaced apart along the length direction of the main body 110. In this way, the turning tool in the tool clamping groove 111 can be fastened by a larger number of bolts.

[0046] like Figure 1 and Figure 3 As shown, in the above embodiment, the size of the connecting portion 120 along the second direction Y can be smaller than the size of the main body 110 along the second direction Y. In this way, when the slot 121 of the connecting portion 120 is inserted into the lathe tool fixture, the end surface of the main body 110 close to the connecting portion 120 can abut against the end surface of the tool fixture, so that the anti-trembling tool bar 100 in this embodiment is more stable in the tool fixture. Specifically, the connecting portion 120 can be connected to the middle position of the main body 110 along the second direction Y to ensure that the anti-trembling tool bar 100 is uniformly stressed. In addition, the size of the connecting portion 120 along the first direction X can be larger than the size of the main body 110 along the first direction X. In this way, the strength lost on the connecting portion 120 due to the provision of the slot 121 can be compensated, and the structural strength of the connecting portion 120 can be ensured. In particular, the second direction Y is perpendicular to the first direction X, and the second direction Y can be consistent with the extension direction of the threaded hole 112.

[0047] In the above embodiment, the cross section of the slot 121 may be rectangular. The slot 121 passes through two opposite sides of the connecting portion 120 along the second direction Y. The slot 121 extends to the end surface of the connecting portion 120 away from the main body 110 .

[0048] In the above embodiment, the size of the slot 121 along the first direction X can be made larger than the size of the slot 121 along the second direction Y. It can be understood that when the turning tool is working, a main direction of the vibration generated thereon is consistent with the first direction X. Therefore, making the size of the slot 121 along the first direction X relatively long can increase the structural strength of the connection between the connecting portion 120 and the turning tool clamp along the first direction X, and increase the vibration resistance of the anti-trembling tool rod 100 along the first direction X.

[0049] In the above embodiment, the ratio of the dimension of the slot 121 along the length direction of the main body 110 to the dimension of the connecting portion 120 along the length direction of the main body 110 can be made smaller than 1:2 to ensure the structural strength of the connecting portion 120 along the length direction of the main body 110 .

[0050] In the above embodiment, the slot 121 can be located in the middle of the connecting portion 120 along the second direction Y to make the structure of the anti-trembling knife rod 100 more uniform, and the size of the slot 121 along the second direction Y is smaller than the size of the main body 110 along the second direction Y.

[0051] The anti-trembling tool rod 100 provided in an embodiment of the present invention is applied to a lathe, and the anti-trembling tool rod 100 includes a main body 110 and a connecting part 120 which are integrally formed along its own length direction, and the connecting part 120 has a clamping groove 121 for clamping with the turning tool fixture of the lathe; the end of the main body 110 facing away from the connecting part 120 forms a tool clamping groove 111, and the tool clamping groove 111 is used to clamp the turning tool. The side wall of the tool clamping groove 111 has at least two threaded holes 112, and the threaded holes 112 are configured to be screwed on by bolts, so that the turning tool in the tool clamping groove 111 can be locked in the tool clamping groove 111 through the abutting force of the end of the bolt. The solution provided by the embodiment of the present invention is to set an anti-trembling tool rod 100 between the lathe tool clamp and the lathe tool. When in use, the lathe tool can be clamped in the tool clamping groove 111 at one end of the anti-trembling tool rod 100, and the bolt is screwed into the threaded hole 112 on the side wall of the tool clamping groove 111. The end of the bolt is used to tightly fix the tool in the tool clamping groove 111 in the tool clamping groove 111, and the anti-trembling tool rod 100 is clamped and fixed to the tool clamp of the lathe through the clamping groove 121 at the other end thereof. In this way, the anti-trembling tool rod 100 can indirectly increase the processing range of the lathe tool and make up for the insufficient length of the lathe tool. The length of the lathe tool itself does not need to be changed, which can prevent the lathe tool from vibrating during use, improve the processing accuracy of the workpiece, and at the same time, reduce the use cost of the lathe tool.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
