Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a positioning device used in conjunction with a CNC machining center. Background Technology

[0002] The main function of the positioning block is to ensure the accuracy of the mold depth and product dimensions. By precisely matching the mold, the positioning block ensures the stability and repeatability of the mold during the opening and closing process, thereby guaranteeing the dimensional accuracy and appearance quality of the product. When processing the positioning block, the blank material needs to be fixed on the table of the CNC machining center, and each surface is milled.

[0003] However, when fixing the positioning block on the worktable of the machining center, the staff needs to accurately locate the position to ensure that each blank is fixed in the same position on the worktable, so as to ensure the consistency of the reference during the processing, reduce the error caused by the change of reference, and ensure the processing accuracy and consistency. This means that the position needs to be accurately located every time a positioning block is processed, which greatly reduces the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for use with CNC machining centers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning device for use with a CNC machining center includes a connecting plate and a support plate fixed to one upper corner of the connecting plate. The upper inner side of the support plate has an opening hole, and a positioning screw is inserted through the inner side of the opening hole. Nut 1 and Nut 2 are respectively engaged with the front and rear ends of the positioning screw near the support plate, and a positioning head is fixedly connected to the rear end of the positioning screw.

[0007] As a further improvement of this utility model: a strip-shaped hole is provided on the inner side of the connecting plate near the front end of the support plate, and a fastening bolt is provided through the inner side of the strip-shaped hole.

[0008] As a further improvement of this utility model, the connecting plate and the supporting plate are perpendicular to each other.

[0009] As a further improvement of this utility model: a washer is provided between the support plate and the first nut, and a sleeve is installed between the support plate and the second nut.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses fastening bolts to securely fix the connecting plate to the worktable of the CNC machining center. By rotating nuts one and two on the positioning screw, the distance between the positioning head and the support plate can be adjusted, so that one end of the positioning head abuts against the positioning block blank to be processed, thus accurately positioning the positioning block blank. After one adjustment, when batch processing other positioning block blanks, simply place the corresponding position of the positioning block blank against the positioning head, and then use the fixture on the CNC machining center to fix the positioning block blank, achieving rapid processing and effectively improving the efficiency of batch processing.

[0016] Please see Figures 1-3 In this embodiment of the present invention, a positioning device for use with a CNC machining center includes a connecting plate 1 and a support plate 4 fixed to one corner of the upper end of the connecting plate 1. An opening 7 is provided at the upper end of the inner side of the support plate 4, and a positioning screw 5 is inserted through the inner side of the opening 7. Nuts 9 and 11 are respectively engaged with the front and rear ends of the positioning screw 5 near the support plate 4. A positioning head 6 is fixedly connected to the rear end of the positioning screw 5. The positioning screw 5 can be securely fixed to the support plate 4 by the nuts 9 and 11. By rotating the nuts 9 and 11 on the positioning screw 5, the distance between the positioning head 6 and the support plate 4 can be adjusted, so that one end of the positioning head 6 abuts against the positioning block blank 12 to be processed, thereby accurately positioning the positioning block blank 12. Figure 3 As shown; once adjusted, when batch processing other positioning block blanks 12, simply place the corresponding position of the positioning block blank 12 against the positioning head 6 and then fix it with the fixture on the CNC machining center, thereby achieving rapid processing.

[0017] exist Figure 2In the middle, the inner side of the connecting plate 1 is provided with a strip hole 3 near the front end of the support plate 4. A fastening bolt 2 is provided through the inner side of the strip hole 3. The connecting plate 1 can be firmly fixed on the material table of the CNC machining center by the fastening bolt 2. And by sliding the fastening bolt 2 in the strip hole 3, the support plate 4 can be fixed at the corresponding position on the material table.

[0018] exist Figure 2 In the middle, the connecting plate 1 and the support plate 4 are perpendicular to each other, so that the positioning screw 5 can be kept parallel to the connecting plate 1.

[0019] exist Figure 2 In the middle, a washer 8 is provided between the support plate 4 and the nut 9, and a sleeve 10 is installed between the support plate 4 and the nut 11. The washer 8 and the sleeve 10 can increase the contact area with the support plate 4, thereby preventing the tightening force of the nut 9 and the nut 11 from acting directly on the nut 11, so as to reduce indentation and damage.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
