Description

Technical Field

[0001] The present application relates to the technical field of guide sleeve processing equipment, and in particular to an open guide sleeve positioning fixture. Background Art

[0002] like Figure 1 , is an open guide sleeve currently processed and produced by our company, which includes a base and a guide sleeve body arranged on the base. The guide sleeve body and the base are both provided with openings for the other components to slide in and out, mainly for avoidance. At the same time, the base is provided with a connection hole for connecting with the loading platform.

[0003] The current processing method of the above-mentioned open guide sleeve is to first process the base and the guide sleeve body through a lathe or a support, and then process the connecting hole on the base through a hole turning mechanism. Then, the opening is milled through a machining center or a milling machine to complete the processing of the product.

[0004] The positioning devices currently used in machining centers and milling machines are usually magnetic positioning tables, vises or three-jaw chucks for clamping and positioning. However, in actual processing, as the depth and width of the opening processing increase, the guide sleeve will open or shrink due to the presence of the notch, resulting in errors in subsequent processing, thereby causing product defects. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides an open guide sleeve positioning fixture, which has the advantages of preventing the guide sleeve body from deforming and ensuring the processing yield.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows:

[0007] An opening guide sleeve positioning fixture comprises a fixed base plate, a positioning sleeve for inserting the guide sleeve body is arranged on the fixed base plate, a tool groove corresponding to the opening is arranged on the positioning sleeve, and the inner wall of the positioning sleeve is in contact with the outer wall of the guide sleeve body;

[0008] A fixing piece for fixing the positioning sleeve on the fixed base plate is arranged at the top end of the positioning sleeve.

[0009] The above technical solution is implemented so that the guide sleeve body is inserted into the positioning sleeve, and then the guide sleeve is fixed on the positioning sleeve by the fixing member. At this time, the milling cutter gradually feeds from the tool groove to mill out the corresponding opening. At this time, the opening of the guide sleeve body is restricted by the positioning of the positioning sleeve when it opens outward, so as to prevent the positioning sleeve from being deformed by the milling of the opening and causing subsequent processing errors. The fixing member fixes the base on the positioning sleeve, so as to prevent the positioning sleeve from shrinking, thereby ensuring the molding quality of the open guide sleeve.

[0010] As a preferred solution of the present application, the height of the positioning sleeve is higher than the height of the guide sleeve body.

[0011] As a preferred solution of the present application, the height of the positioning sleeve is 0.5-5 cm higher than the height of the guide sleeve body.

[0012] The above technical solution is implemented to ensure that the guide sleeve body can be completely wrapped and restricted by the positioning sleeve, thereby ensuring the processing accuracy.

[0013] As a preferred solution of the present application, the fixing member includes a positioning hole arranged on the top of the positioning sleeve, the positioning hole is arranged in a one-to-one correspondence with the connecting hole, and a positioning screw is threaded into the positioning hole.

[0014] To implement the above technical solution, after the base is placed on the positioning sleeve, the positioning screw passes through the base and is screwed into the positioning hole, so that the base is screwed and locked in the positioning sleeve. At this time, the guide sleeve body can be prevented from rotating, and the guide sleeve body can be prevented from shrinking due to the gradual expansion of the opening, thereby ensuring the processing yield of the product.

[0015] As a preferred solution of the present application, a chamfer is provided on the top of the inner wall of the positioning sleeve.

[0016] The above technical solution is implemented to facilitate the insertion of the guide sleeve body into the positioning sleeve.

[0017] As a preferred solution of the present application, a C-shaped spring piece is provided at the bottom wall of the positioning sleeve, and the C-shaped spring piece abuts against the inner wall of the positioning sleeve.

[0018] As a preferred solution of the present application, handles are provided at both ends of the C-shaped spring piece.

[0019] To implement the above technical solution, after milling is completed, the waste chips accumulated at the bottom of the positioning sleeve can be moved up and down by controlling the C-shaped spring piece through the handle, thereby scraping off the waste chips adhering to the inner wall of the positioning sleeve to ensure the subsequent insertion of the guide sleeve body.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The guide sleeve body is inserted into the positioning sleeve, and then the guide sleeve is fixed on the positioning sleeve by the fixing part. At this time, the milling cutter gradually feeds from the tool groove to mill out the corresponding opening. At this time, the opening of the guide sleeve body is restricted by the positioning sleeve when it opens outward to prevent the positioning sleeve from being deformed by the milling of the opening, resulting in subsequent processing errors. The fixing part fixes the base on the positioning sleeve, thereby preventing the positioning sleeve from shrinking inward, thereby ensuring the molding quality of the open guide sleeve.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The present application embodiment discloses an open guide sleeve positioning fixture. Figure 1-2 The opening guide sleeve positioning fixture includes a fixed base plate 3, on which a positioning sleeve 4 is provided for inserting the guide sleeve body 2, and on which a tool groove 5 corresponding to the opening is provided, and the inner wall of the positioning sleeve 4 fits with the outer wall of the guide sleeve, and a fixing piece for fixing the base 1 is provided at the top of the positioning sleeve 4. Thus, the guide sleeve body 2 is inserted into the positioning sleeve 4, and then the guide sleeve is fixed to the positioning sleeve 4 by the fixing piece. At this time, the milling cutter gradually feeds from the tool groove 5, thereby milling out the corresponding opening. At this time, when the opening of the guide sleeve body 2 opens outward, it is restricted by the positioning of the positioning sleeve 4, so as to prevent the positioning sleeve 4 from being deformed due to the milling of the opening, resulting in subsequent processing errors. And the fixing piece fixes the base 1 on the positioning sleeve 4, so as to prevent the positioning sleeve 4 from shrinking, thereby ensuring the molding quality of the opening guide sleeve.

[0029] Reference Figure 2-3 The fixing part includes a positioning hole arranged at the top of the positioning sleeve 4. The positioning hole and the connecting hole are arranged one by one. A positioning screw 6 is threaded in the positioning hole. That is, after the base 1 is placed on the positioning sleeve 4, the positioning screw 6 passes through the base 1 and is threaded in the positioning hole, so that the base 1 is screwed and locked in the positioning sleeve 4. At this time, the guide sleeve body 2 can be prevented from rotating, and the guide sleeve body 2 can be prevented from shrinking due to the gradual expansion of the opening, thereby ensuring the processing yield of the product.

[0030] The height of the positioning sleeve 4 is higher than that of the guide sleeve body 2 to ensure that the guide sleeve body 2 can be completely wrapped and restricted by the positioning sleeve 4, thereby ensuring the processing accuracy. The height of the positioning sleeve 4 is 0.5-5 cm higher than that of the guide sleeve body 2, so that the cutting grinding can fall off and discharge, thereby ensuring the normal milling.

[0031] A chamfer is provided at the top of the inner wall of the positioning sleeve 4 to facilitate the insertion of the guide sleeve body 2 into the positioning sleeve 4 .

[0032] A C-shaped spring piece 7 is provided at the bottom wall of the positioning sleeve 4, and the C-shaped spring piece 7 abuts against the inner wall of the positioning sleeve. Both ends of the C-shaped spring piece 7 are provided with handles 8. That is, when milling is completed, the waste chips accumulated at the bottom of the positioning sleeve 4 can be controlled by the handle 8 to move up and down, so as to scrape off the waste chips adhering to the inner wall of the positioning sleeve 4, so as to ensure the subsequent insertion of the guide sleeve body 2. At the same time, the C-shaped spring piece 7 can be contracted by holding, and then attached to the fixed substrate 3, so as to move out of the tool groove 5, thereby ensuring the cleanliness of the fixed substrate 3, so as to ensure the normal processing of the subsequent guide sleeve body 2.

[0033] The implementation principle of an open guide sleeve positioning fixture in the embodiment of the present application is as follows: the guide sleeve body 2 is inserted into the positioning sleeve 4, and then the guide sleeve is fixed to the positioning sleeve 4 by a fixing member. At this time, the milling cutter gradually feeds from the tool groove 5, thereby milling out the corresponding opening. At this time, the opening of the guide sleeve body 2 is restricted by the positioning of the positioning sleeve 4 when it opens outward, so as to prevent the positioning sleeve 4 from deforming due to milling of the opening and causing subsequent processing errors. The fixing member fixes the base 1 on the positioning sleeve 4, thereby preventing the positioning sleeve 4 from shrinking inward, thereby ensuring the molding quality of the open guide sleeve.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
