Description

Technical Field

[0001] The utility model discloses a novel vertical lathe tool rest seat, belonging to the technical field of lathe accessories. Background Art

[0002] Vertical lathe is abbreviated as "vertical lathe". It is mainly used to process large and heavy workpieces with large diameter and short length, and workpieces that are not easy to clamp on horizontal lathes. When the rotation diameter is met, workpieces that are too heavy are not easy to clamp on horizontal lathes. Due to their own weight, the processing accuracy is affected. The use of vertical lathes can solve the above problems.

[0003] A tool holder seat is installed on the movable arm of the vertical lathe, and the turning tool is installed on the tool holder seat. At present, the common installation method of the tool holder seat is to adopt a dovetail groove connection. The vertical direction is limited by the clamping connection between the dovetail groove and the block. The installation is simple and convenient. However, the existing tool holder seat is installed by arranging bolts from the inside toward the dovetail block to press the mounting seat, so as to achieve the purpose of stability. Since the installation direction of the bolt is the same as the direction of the top pressure, after a period of use, the bolt will become loose due to vibration, thereby reducing the top pressure, resulting in poor stability of the tool holder seat, and ultimately affecting the processing accuracy of the material. In order to solve this problem, the utility model proposes a new solution. Utility Model Content

[0004] The purpose of the utility model is to provide a novel vertical lathe tool holder seat in order to solve the above-mentioned problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a novel vertical lathe tool holder seat, including a main body, a dovetail protrusion is arranged on the main body, a mounting notch is arranged on one side of the dovetail protrusion of the main body, a top pressure stabilizing block is arranged in the mounting notch, the top pressure stabilizing block is fitted with the inner wall of the mounting notch, an inclined top pressure mechanism is arranged between the top pressure stabilizing block and the mounting notch, and the top pressure stabilizing block is fixed to the main body through a mounting component.

[0006] Preferably, the mounting notch forms a straight surface and an inclined surface one, the inclined top-pressing mechanism includes an inclined surface one and an inclined surface two, the inclined surface one is located on the inner wall of an end of the mounting notch away from the dovetail protrusion, the inclined surface two is arranged on the top-pressing stabilizing block and is located on an end of the top-pressing stabilizing block close to the main body, and the inclined surface one abuts against the inclined surface two.

[0007] Preferably, the installation component 1 includes a plurality of bolts 1, the top pressure stabilizing block is provided with a plurality of threaded holes 1 evenly arranged along the length direction, the threaded hole 1 penetrates the top pressure stabilizing block, and the flat surface of the installation notch is provided with a threaded hole 2 aligned with the threaded hole 1, and the bolt 1 is threadedly connected with the threaded hole 1 and the threaded hole 2 in sequence.

[0008] Preferably, a tool groove for mounting a turning tool is provided on the main body, and the tool groove is a U-shaped groove.

[0009] Preferably, the turning tool is fixed in the turning tool groove by means of a second mounting assembly.

[0010] Preferably, the mounting assembly 2 includes a plurality of bolts 2, the main body is provided with a threaded hole 3 at the position of the turning tool groove, the threaded hole 3 extends from the outer wall of one side of the main body into the turning tool groove, the bolt 2 is threadedly connected to the threaded hole 3, and the bolt 2 abuts against the turning tool.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] An installation notch and a top-pressure stabilizing block are provided on one side of the dovetail protrusion of the vertical lathe tool holder seat, and are connected by a laterally installed bolt. The installation notch and the inclined surface of the top-pressure stabilizing block will cause the top-pressure stabilizing block to generate a pressing force toward the side of the dovetail protrusion, thereby stabilizing the tool holder seat. Since the direction of the pressing force for stabilizing the tool holder seat is perpendicular to the installation direction of the bolt, even if the screw is slightly loosened, the top-pressure stabilizing block can still maintain the top pressure on the tool holder seat, greatly reducing the possible impact on material processing accuracy.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, the existing vertical lathe tool holder seat is stabilized by arranging bolts therein from the inside toward the dovetail block to press the mounting seat. Since the installation direction of the bolts is the same as the direction in which the pressing force is applied, after a period of use, the bolts will become loose due to vibration, thereby reducing the pressing force, causing the tool holder seat to become less stable, and ultimately affecting the processing accuracy of the material.

[0019] like Figure 2 , Figure 3 As shown, the new vertical lathe tool holder seat of this embodiment includes a main body 1, and a dovetail protrusion 2 is arranged on the top of the main body 1, and the dovetail protrusion 2 can be embedded in the dovetail groove on the moving arm of the vertical lathe from the side; the main body 1 is provided with a mounting notch 3 on one side of the dovetail protrusion 2, and the main body 1 will form a straight surface 8 and an inclined surface 9 at the mounting notch 3, wherein the straight surface 8 is a vertical surface, and the inclined surface 9 is a surface inclined downward from the inside to the outside; a top pressure stabilizing block 4 is also arranged in the mounting notch 3, and the top pressure stabilizing block 4 is in contact with the inner wall of the mounting notch 3, and the top pressure stabilizing block 4 can stabilize the tool holder seat by opposing the moving arm.

[0020] An inclined pressing mechanism is provided between the pressing and stabilizing block 4 and the mounting notch 3, and the inclined pressing mechanism includes an inclined surface 1 9 and an inclined surface 2 10, wherein the inclined surface 1 9 is located on the inner wall of the end of the mounting notch 3 away from the dovetail protrusion 2, and the inclined surface 2 10 is provided on the pressing and stabilizing block 4, and is located on the end of the pressing and stabilizing block 4 close to the main body 1, and the inclined surface 1 9 is in contact with the inclined surface 2 10. By installing the pressing and stabilizing block 4, the inclined surface 1 9 will fit with the inclined surface 2 10, and the two will be against each other. Under the action of the inclined surface, the pressing and stabilizing block 4 will simultaneously generate inward and upward forces, and the upward force will press the movable arm, so that the dovetail protrusion 2 can be stabilized in the dovetail groove of the movable arm.

[0021] The top pressure stabilizing block 4 is fixed to the body 1 through the mounting assembly 15. The mounting assembly 15 includes a plurality of bolts 11, and the top pressure stabilizing block 4 is provided with a plurality of threaded holes 12 evenly arranged along the length direction. The threaded hole 12 penetrates the top pressure stabilizing block 4, and the flat surface 8 of the mounting notch 3 is provided with a threaded hole 2 13 aligned with the threaded hole 12. The bolt 11 is threadedly connected with the threaded hole 12 and the threaded hole 2 13 in sequence. Therefore, when installing the top pressure stabilizing block 4, it is only necessary to align the threaded hole 12 with the threaded hole 2 13 first, and then screw the bolt 11 in. It should be noted that Yes, before the tool holder seat is installed on the movable arm, there is no need to tighten the bolt 11. Only when the tool holder seat is installed on the movable arm, the bolt 11 is tightened. At this time, under the action of the inclined surface 19 and the inclined surface 2 10, the top pressure stabilizing block 4 will be slightly adjusted upward to resist the movable arm, so that the dovetail protrusion 2 can be stabilized in the dovetail groove of the movable arm. Moreover, since the direction of the resisting force for stabilizing the tool holder seat is perpendicular to the installation direction of the bolt 11, even if the bolt 11 is slightly loosened, the top pressure stabilizing block 4 can still maintain the top pressure on the tool holder seat, which greatly reduces the possible impact on the material processing accuracy.

[0022] A turning tool groove 6 is provided on the main body 1, and the turning tool groove 6 is a U-shaped groove, which can be used to install a turning tool; the turning tool is fixed in the turning tool groove 6 through an installation component 2 7, and the installation component 2 7 includes a plurality of bolts 2 14. The main body 1 is provided with a threaded hole 3 15 at the position of the turning tool groove 6, and the threaded hole 3 15 extends from the outer wall of one side of the main body 1 to the turning tool groove 6, the bolt 2 14 is threadedly connected with the threaded hole 3 15, and the bottom of the bolt 2 14 abuts against the turning tool after passing through the threaded hole 3 15, thereby firmly fixing the turning tool in the turning tool groove 6.
