[0002] For lathes, aligning the workpiece when clamping it on the lathe spindle is difficult, and a long time is required for alignment each time a workpiece is processed, resulting in long downtime of the lathe, which is very detrimental to cost control. The adjustable jaw clamping device disclosed in CN206200159U "An Adjustable Jaw Clamping Device for CNC Lathe Chuck" can clamp the workpiece and is suitable for clamping and processing thin-walled parts. It has a good clamping effect on the workpiece, but it cannot perform fine adjustment and alignment of the workpiece. Utility Model Content
[0003] To solve the above-mentioned technical problems, one of the objectives of this utility model is to provide a lathe tooling with a simple structure and capable of fine-tuning and alignment.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A lathe tooling with fine-tunable alignment includes a base, an adjusting block, and a fixture. A clamping member is provided on one side of the base, and a clamping opening is provided in the middle of the clamping member. The adjusting block is placed in the clamping opening. The clamping member is used to clamp the adjusting block and adjust its position. The fixture is provided on the side of the adjusting block away from the base.
[0005] The beneficial effects of the above technical solution are as follows: by installing the fixture on the adjusting block and clamping the adjusting block on the base by the clamping component, the clamping component can make fine adjustments to the position of the adjusting block and the fixture in the plane when clamping the adjusting block, so as to improve the accuracy of workpiece processing.
[0006] The clamping component described in the above technical solution includes multiple abutment bars and multiple clamping bolts. The multiple abutment bars are fixedly mounted on the base and form an annular clamping opening. Each abutment bar is threaded with at least one clamping bolt. The clamping bolt passes through the abutment bar and is threadedly connected to the abutment bar, with its threaded end located inside the clamping opening. Tightening the multiple clamping bolts can clamp the adjusting block together, or loosening the multiple clamping bolts can release the adjusting block from the clamp together (preferably, the multiple clamping bolts can be distributed in pairs, and for two oppositely distributed clamping bolts, one can be loosened while the other is tightened, so that the adjusting block can be offset to one side).
[0007] The beneficial effects of the above technical solution are: its structure is simple, which allows multiple clamping bolts to clamp the adjusting block in the clamping jaws from the ring upwards, and to coordinately adjust the tightness of each clamping bolt to adjust the position of the adjusting block horizontally.
[0008] The above technical solution describes the following: four abutment strips are provided, and the four abutment strips are installed end to end and enclose to form a square clamp. The adjusting block is a square plate.
[0009] The beneficial effect of the above technical solution is that its structure is simple.
[0010] In the above technical solution, each of the abutment bars has 2-4 clamping bolts spaced apart along its length.
[0011] The beneficial effect of the above technical solution is that its structure is simple, which allows multiple clamping bolts to clamp the adjusting block circumferentially from different positions.
[0012] In the above technical solution, the middle part of the abutment strip is recessed on one side near the clamp, and the adjusting block is protruding at the position corresponding to the limiting notch, and the limiting block extends into the corresponding limiting notch.
[0013] The beneficial effect of the above technical solution is that it makes the adjusting block less likely to loosen within the clamp.
[0014] The fixture described in the above technical solution includes a lower clamping block and an upper clamping block. The lower clamping block is fixedly disposed on the side of the adjusting block away from the base, and the upper clamping block is detachably mounted on the lower clamping block. The upper and lower clamping blocks are used to clamp the workpiece together.
[0015] The beneficial effect of the above technical solution is that the upper clamping block and the lower clamping block can cooperate to clamp the workpiece.
[0016] In the above technical solution, the lower clamping block is recessed with a threaded hole, and the upper clamping block is provided with a through hole aligned with the threaded hole. The through hole and the threaded hole aligned with it are used for inserting a connecting bolt to install the upper clamping block on the lower clamping block.
[0017] The beneficial effect of the above technical solution is that the upper clamping block and the lower clamping block can be connected by connecting bolts to clamp the workpiece.
[0018] In the above technical solution, the lower end of the upper clamping block is provided with a first clamping groove, and / or the upper end of the lower clamping block is provided with a second clamping groove.
[0019] The beneficial effect of the above technical solution is that it enables the workpiece to be clamped between the upper clamping block and the lower clamping block.
[0020] The second objective of this invention is to provide a lathe with a simple structure that allows for convenient fine-tuning and alignment.
[0021] To achieve the above objectives, another technical solution of this utility model is as follows: a lathe, comprising a lathe body and a finely adjustable lathe fixture as described above, wherein the finely adjustable lathe fixture is mounted on the spindle of the lathe body.
[0022] The beneficial effect of the above technical solution is that it enables the lathe to finely adjust and align the position of the workpiece using the finely adjustable lathe tooling.
[0023] The lathe body described in the above technical solution also includes a three-jaw chuck, which is mounted on the spindle and is used to clamp the base.
[0024] The beneficial effect of the above technical solution is that the finely adjustable lathe tooling is clamped by a three-jaw chuck. Attached Figure Description

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0030] like Figure 1 and Figure 2As shown, this embodiment provides a lathe comprising a lathe body and a fine-tunable alignment tooling 100. The fine-tunable alignment tooling 100 is mounted on the spindle of the lathe body, allowing the lathe to fine-tune and align the workpiece position using the tooling. Preferably, the lathe body further includes a three-jaw chuck 200, which is disposed on the spindle and used to clamp the base 1, thus enabling the fine-tunable alignment tooling to be clamped by the three-jaw chuck.
[0031] like Figure 1 and Figure 2 As shown, the fine-tunable lathe fixture 100 provided in this embodiment includes a base 1, an adjusting block 2, and a fixture 3. A clamping member 4 is provided on one side of the base 1, and the clamping member 4 has a clamping opening in the middle. The adjusting block 2 is placed in the clamping opening. The clamping member 4 is used to clamp the adjusting block 2 and adjust its position. The fixture 3 is located on the side of the adjusting block 2 away from the base 1. The fixture 3 is used to clamp the workpiece. By installing the fixture on the adjusting block and clamping it onto the base, the clamping member can fine-tune the position of the adjusting block and the fixture in a plane while clamping the adjusting block, thereby improving the accuracy of workpiece machining. In this embodiment, the base is a circular plate.
[0032] like Figure 1 and Figure 2 As shown, the clamping member 4 in the above technical solution includes multiple abutment bars 41 and multiple clamping bolts 42. The multiple abutment bars 41 are fixedly disposed on the base 1 and form an annular clamping opening. Each abutment bar 41 is threaded with at least one clamping bolt 42. The clamping bolt 42 passes through the abutment bar 41 and is threadedly connected to the abutment bar 41, and its threaded end is located inside the clamping opening. Tightening the multiple clamping bolts 42 together clamps the adjusting block 2, or loosening the multiple clamping bolts 42 together releases the adjusting block 2 from the clamping opening. Its structure is simple, so that the multiple clamping bolts can clamp the adjusting block in the clamping opening from the annular direction, and coordinately adjust the tightness of each clamping bolt to adjust the position of the adjusting block horizontally.
[0033] like Figure 1 and Figure 2 As shown, the above technical solution has four abutment strips 41. The four abutment strips 41 are installed end to end and enclose to form a square clamping opening. The adjusting block 2 is a square plate with a simple structure. By setting the adjusting block as a square plate, the adjusting block is placed inside the square clamping opening, and the clamping effect of multiple clamping bolts on the adjusting block from the ring upward is better.
[0034] like Figure 1 and Figure 2 As shown, in the above technical solution, each abutment bar 41 has 2-4 clamping bolts 42 spaced apart along its length. Its structure is simple, allowing multiple clamping bolts to clamp the adjusting block circumferentially from different positions. Preferably, in this embodiment, two clamping bolts are spaced apart on the abutment bar, and each clamping bolt is perpendicular to the corresponding abutment bar.
[0035] In the above technical solution, the middle of the abutment strip 41 near the clamping opening has a recessed limiting notch 411, and the adjusting block 2 has a protruding limiting block 21 corresponding to the limiting notch 411. The limiting block 21 extends into the corresponding limiting notch 411, thus making the adjusting block less prone to loosening within the clamping opening. The limiting notch is an arc-shaped notch, and the limiting block cooperates with the limiting notch.
[0036] like Figure 3 As shown, the clamp 3 in the above technical solution includes a lower clamping block 31 and an upper clamping block 32. The lower clamping block 31 is fixedly disposed on the side of the adjusting block 2 away from the base 1. The upper clamping block 32 is detachably mounted on the lower clamping block 31. The upper clamping block 32 and the lower clamping block 31 are used to clamp the workpiece together, so that the upper clamping block and the lower clamping block can cooperate to clamp the workpiece.
[0037] like Figure 3 As shown, in the above technical solution, the lower clamping block 31 is recessed with a threaded hole 311, and the upper clamping block 32 is provided with a through hole 321 aligned with the threaded hole 311. The through hole 321 and the threaded hole 311 aligned therewith are used for inserting a connecting bolt 33 to install the upper clamping block 32 on the lower clamping block 31, so that the upper clamping block and the lower clamping block can be connected by a connecting bolt to clamp the workpiece.
[0038] like Figure 3 As shown, in the above technical solution, the lower end of the upper clamping block 32 is provided with a first clamping groove 322, and / or the upper end of the lower clamping block 31 is provided with a second clamping groove 312, so that the workpiece can be clamped between the upper clamping block and the lower clamping block. In this embodiment, the first clamping groove and the second clamping groove are aligned with each other and are both perpendicular to the adjusting block, and the workpiece 300 is used to clamp in the area between the first clamping groove and the second clamping groove.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
