Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machining, in particular to a racket-shaped workpiece clamping sleeve. Background Art
[0002] A racket-shaped workpiece refers to a workpiece that is shaped like a racket. The processing of the rod of the racket-shaped workpiece can be achieved by a lathe, but the lathe generally uses a three-jaw chuck to clamp the workpiece.
[0003] There are two ways to clamp a racket-shaped workpiece with a three-jaw chuck. One is to clamp the flat end of the racket-shaped workpiece. However, since the clamping part is flat, the three-jaw chuck often only has two jaws to clamp the workpiece, which is not stable. The other is to clamp the rod of the racket-shaped workpiece. However, this method also has problems, that is, clamping the flat end of the racket-shaped workpiece will interfere with the movement of the tool. The rod close to the flat end will be blocked by the tool and cannot be cut. Therefore, the present application proposes a racket-shaped workpiece clamping sleeve to solve the above problem. Utility Model Content
[0004] The main purpose of the utility model is to provide a racket-shaped workpiece clamping sleeve, wherein the clamping component can clamp the oblate portion of the racket-shaped workpiece, and the clamping component can be inserted into the sleeve. At this time, the rod body to be processed of the racket-shaped workpiece is located outside the sleeve, so that the three-jaw chuck of the lathe fixes the racket-shaped workpiece by clamping the sleeve, so as to facilitate the cutting operation on it, improve the clamping stability, and the rod body close to the oblate portion can also be cut normally.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A racket-shaped workpiece clamping sleeve includes a through sleeve with a matching clamping assembly inserted into the sleeve. The clamping assembly consists of a first clamping piece and a second clamping piece. The contact surfaces of the first clamping piece and the second clamping piece are both provided with a positioning groove and a through groove for accommodating the racket-shaped workpiece, and the positioning groove and the through groove are connected.
[0007] Furthermore, the jacket is provided with a notch along the insertion direction of the clamping assembly.
[0008] Furthermore, the first clip and the second clip have the same structure and are symmetrically arranged.
[0009] Furthermore, the clamping assembly is a cylinder.
[0010] Furthermore, the jacket is a hollow cylinder, and the clamping assembly and the jacket are transitionally fitted.
[0011] Furthermore, the entry end of the racket-shaped workpiece of the positioning groove is provided with a chamfer.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The clamping assembly of the utility model can clamp the oblate part of the racket-shaped workpiece, and the clamping assembly can be inserted into the sleeve. At this time, the rod body to be processed of the racket-shaped workpiece is located outside the sleeve, so that the three-jaw chuck of the lathe fixes the racket-shaped workpiece through the clamping sleeve to facilitate the cutting operation, improve the clamping stability, and the rod body close to the oblate part can also be cut normally.
[0014] The notch of the utility model can make the jacket deform more easily after being subjected to force, thereby making it easier for personnel to insert or pull out the clamping assembly from the jacket. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-5 As shown, a racket-shaped workpiece clamping sleeve includes a through sleeve 1, in which a matching clamping assembly 2 is inserted, and the clamping assembly 2 consists of a first clamping piece 201 and a second clamping piece 202. The contact surfaces of the first clamping piece 201 and the second clamping piece 202 are provided with a positioning groove 2012 and a through groove 2011 for accommodating the racket-shaped workpiece, and the positioning groove 2012 and the through groove 2011 are connected.
[0023] In this embodiment, if Figure 1 and Figure 2As shown, the through slot 2011 of the first clamp 201 extends to the end of the first clamp 201, and the through slot 2011 of the second clamp 202 extends to the end of the second clamp 202. Therefore, when installing a racket-shaped workpiece, the head of the racket-shaped workpiece can be inserted into the positioning slot 2012 of the first clamp 201, and then the rod of the racket-shaped workpiece can be inserted into the through slot 2011 of the first clamp 201 and pass through the through slot 2011, thereby preliminarily fixing the racket-shaped workpiece on the first clamp 201 (part of the racket-shaped workpiece will be located in the first clamp). The second clamp 202 is assembled with the first clamp 201, so that the second clamp 202 also limits the racket-shaped workpiece through its own positioning groove 2012 and through groove 2011, and then the assembled first clamp 201 and second clamp 202 are inserted into the jacket 1, and the jacket 1 is fixed in the three-jaw chuck of the lathe, thereby improving the fixing stability of the racket-shaped workpiece and avoiding the racket-shaped workpiece from shaking during rotation due to poor clamping effect.
[0024] Among them, such as Figure 1 and Figure 3 As shown, the jacket 1 is provided with a notch 3 along the insertion direction of the clamping component 2. The notch 3 can make the jacket 1 more easily deformed after being subjected to force, thereby making it easier for personnel to insert or remove the clamping component 2 from the jacket 1.
[0025] Among them, such as Figure 1 As shown, the first clamping piece 201 and the second clamping piece 202 have the same structure and are symmetrically arranged. Therefore, when clamping a racket-shaped workpiece, the portions of the racket-shaped workpiece located within the first clamping piece 201 and the second clamping piece 202 are the same. Therefore, compared to when the racket-shaped workpiece is completely located within the first clamping piece 201 or completely located within the second clamping piece 202, the design of the present set can more easily remove the racket-shaped workpiece from the first clamping piece 201 and the second clamping piece 202.
[0026] Among them, such as Figure 1 As shown, the clamping assembly 2 is a cylinder and the jacket 1 is a hollow cylinder. Therefore, the clamping assembly 2 is easy to insert into the jacket 1. The clamping assembly 2 and the jacket 1 are transitionally matched, which is convenient for assembly and disassembly.
[0027] Among them, such as Figure 2 As shown, the entry end of the racket-shaped workpiece of the positioning groove 2012 is provided with a chamfer 2013 to facilitate personnel to insert the head of the racket-shaped workpiece into the positioning groove 2012.
[0028] Working principle: First, the staff inserts the head of the racket-shaped workpiece into the positioning groove 2012 of the first clamp 201, and then inserts the rod of the racket-shaped workpiece into the through groove 2011 of the first clamp 201. At this time, part of the racket-shaped workpiece is located outside the positioning groove 2012 and the through groove 2011 of the first clamp 201. Then, the second clamp 202 is assembled with the first clamp 201, so that the second clamp 202 is also aligned with the first clamp 201 through its own positioning groove 2012 and the through groove 2011. 01 is limited, and the racket-shaped workpiece outside is completely fixed in the clamping assembly 2. At this time, the rod portion to be processed of the racket-shaped workpiece will be located outside the clamping assembly 2, and then the assembled first clamp 201 and second clamp 202 are inserted into the collet 1, and the collet 1 is fixed in the three-jaw chuck of the lathe, so that the racket-shaped workpiece is clamped and fixed by this set, thereby improving the clamping stability of the racket-shaped workpiece and avoiding the racket-shaped workpiece from shaking during rotation due to poor clamping effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
