Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a long rod cutting tool fixing system. Background Art

[0002] Long-rod cutting tools are mainly used for axial processing of the outer circle of products. The working principle is that the tool is long and fixed, and the product is fed in the direction of the tool while rotating. Therefore, the longer the tool is, the greater the deflection deformation the tool will bear during the cutting process, and the more unstable it will be. Not only will the product processing accuracy be affected, but the tool itself will also be seriously damaged due to the deflection deformation and restoring force. Based on the above analysis, long-rod cutting tools have stability problems during use due to their long length. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a long-pole cutting tool fixing system. By designing an adjustable support structure at the position of the tool head, it is not only possible to compensate for the influence of the force deformation of the cutting tool, but also to fine-tune the height of the tool according to the need of support strength, thereby solving the problem of unstable support and non-fine-tuning height of the long-pole cutting tool in the prior art.

[0004] In order to solve the above technical problems, the utility model provides a long-rod cutting tool fixing system, including: a lathe fixing bracket, a long-rod cutting tool, a tool support seat, and a tool support rod. The rear end of the long-rod cutting tool is fixed on the lathe fixing bracket, and the long-rod cutting tool is arranged horizontally; the lower part of the front end of the long-rod cutting tool is vertically supported in the tool support hole of the tool support seat by the tool support rod; and a double-inclined iron fine-tuning structure is arranged in the tool support hole, and the bottom of the tool support rod is supported on the double-inclined iron fine-tuning structure.

[0005] The side surface of the tool support hole is abutted against the side surface of the tool support rod through a screw.

[0006] The double-inclined iron fine-tuning structure includes a first inclined iron placed with an inclined surface facing upward, a second inclined iron placed with an inclined surface facing downward, a first tightening screw horizontally abutting against the right-angled side of the first inclined iron, and a second tightening screw horizontally connected to the right-angled side of the second inclined iron. The second inclined iron cooperates with the inclined surface of the first inclined iron, and the inclination angles of the two inclined surfaces are the same.

[0007] The inclination angles of the inclined surfaces of the first inclined iron and the second inclined iron relative to the horizontal plane are between 35 and 40 degrees.

[0008] The length and width of the first oblique iron and the second oblique iron in the horizontal direction are both smaller than the size of the tool support hole, so that the first oblique iron and the second oblique iron can move horizontally in the tool support hole.

[0009] Screw holes are respectively provided on the side wall of the tool support hole corresponding to the first tightening screw and the second tightening screw.

[0010] The first tightening screw and the second tightening screw are both hexagon socket screws.

[0011] The tool support seat is an inverted T-shaped structure as a whole, thereby obtaining a larger supporting area.

[0012] The lathe fixing bracket is provided with a tool fixing groove in a horizontal direction, and a fixing screw installed vertically is provided on the top of the tool fixing groove.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figure 1-4 As shown, the utility model provides a long-rod cutting tool fixing system, including: a lathe fixing bracket 1, a long-rod cutting tool 2, a tool support seat 3, and a tool support rod 4. The rear end of the long-rod cutting tool 2 is fixed on the lathe fixing bracket 1, and the long-rod cutting tool 2 is arranged horizontally; the lower part of the front end of the long-rod cutting tool 2 is vertically supported in the tool support hole 41 of the tool support seat 3 by the tool support rod 4; and a double-bevel iron fine-tuning structure 5 is provided in the tool support hole 41, and the bottom of the tool support rod 4 is supported on the double-bevel iron fine-tuning structure 5. In the technical solution of the utility model, the length of the long-rod cutting tool 2 is usually long and the span is large, so after the rear end of the long-rod cutting tool 2 is fixed, the front end forms a suspended state. When it contacts and cuts with the workpiece, due to the strong cutting force, it is easy to cause the deformation of the long-rod cutting tool 2. And further, the support height of the tool support rod 4 can be fine-tuned by the double-bevel iron fine-tuning structure 5, so as to adapt to cutting deformations of different intensities.

[0025] The side surface of the tool support hole 41 is abutted against the side surface of the tool support rod 4 by screws, so that the tool support rod 4 can be fixed to prevent the tool support rod 4 from being unstable during the supporting process.

[0026] The double-inclined iron fine-tuning structure 5 includes a first inclined iron 51 with an upwardly inclined surface, a second inclined iron 52 with a downwardly inclined surface, a first jacking screw 53 horizontally abutting against the right-angled side of the first inclined iron 51, and a second jacking screw 54 horizontally low-connected to the right-angled side of the second inclined iron 52. The second inclined iron 52 matches the inclined surface of the first inclined iron 51, and the two inclined surfaces have the same inclination angle. Through the matching connection of the two inclined irons and the adjustment of the two jacking screws, the matching height between the two inclined irons can be controlled, thereby achieving the adjustment of the support height of the long-bar cutting tool 2.

[0027] The inclination angle of the inclined surfaces of the first inclined iron 51 and the second inclined iron 52 relative to the horizontal plane is between 35 and 40 degrees. When selecting the inclination angle, it is necessary to comprehensively consider the cross-sectional dimensions of the tool support hole 41 and the design requirements of the height stroke to be fine-tuned. Since the space in the tool support hole 41 is limited, the dimensions of the two inclined irons must be smaller than the dimensions of the tool support hole 41, so that the inclined irons must consider these important factors when selecting the inclination angle. Because the smaller the inclination angle, the higher the adjustment accuracy, but it also reduces the maximum adjustment stroke.

[0028] The length and width of the first oblique iron 51 and the second oblique iron 52 in the horizontal direction are both smaller than the size of the tool support hole 41 , so that the first oblique iron 51 and the second oblique iron 52 can move horizontally in the tool support hole 41 .

[0029] Screw holes are respectively provided on the side wall of the tool support hole 41 corresponding to the first tightening screw 53 and the second tightening screw 54 , so that the two tightening screws can be easily connected to the tool support seat 3 .

[0030] The first tightening screw 53 and the second tightening screw 54 are both hexagon socket screws.

[0031] The tool support seat 3 is an inverted T-shaped structure as a whole, so as to obtain a larger supporting area, which makes the supporting effect of the tool support seat 3 better and more stable.

[0032] The lathe fixing bracket 1 is provided with a tool fixing groove 11 in a horizontal direction, and a fixing screw 12 installed vertically is provided at the top of the tool fixing groove 11. The tool fixing groove 11 is located at the side of the lathe fixing bracket 1 and is arranged horizontally. The size of the tool fixing groove 11 should be slightly larger than the cross-sectional size of the long-bar type cutting tool 2, so that the long-bar type cutting tool 2 can be loaded into the tool fixing groove 11; then the fixing screw 12 passes through the screw hole on the lathe fixing bracket 1 and penetrates the tool fixing groove 11, and abuts against the side of the long-bar type cutting tool 2, so that the long-bar type cutting tool 2 is fixed in the tool fixing groove 11.

[0033] There are two or more fixing screws 12 , which are arranged at intervals along the longitudinal direction (horizontal direction) of the tool fixing groove 11 , so that the long rod cutting tool 2 can be positioned at multiple points, and the fixing effect of the long rod cutting tool 2 is better.

[0034] The long-rod cutting tool fixing system provided by the utility model provides support for the front end of the long-rod cutting tool through a tool support seat and a tool support rod, and fine-adjusts the height of the tool support rod through a double-bevel iron fine-adjustment structure, so that the long-rod cutting tool can meet the stability requirements of tool cutting.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
