Description

Technical Field

[0001] The utility model relates to the technical field of multi-step parts processing, in particular to a multi-step punching and positioning device for a processing center. Background Art

[0002] A multi-step part refers to a part with multiple cylinders of different diameters. These cylinders are connected by shoulders to form a step-like structure. When performing drilling operations on multi-step parts in a machining center, a special positioning device is usually required to ensure the accuracy of the hole position and processing efficiency.

[0003] The positioning devices used for multi-step punching are quite diverse. For example, a multi-step punching positioning device for a machining center disclosed in Chinese patent CN217345232U includes a base, a pressure plate one, a workpiece, a double pressure plate, a pressure plate two and a locking bolt. The positioning device improves the machining efficiency and provides convenience for people. However, the existing positioning devices used for multi-step punching still have the disadvantage of inconvenient operation, because the traditional positioning devices for multi-step punching either use an automated process, which is costly and inconvenient to operate, or perform clamping operations in multiple steps, resulting in cumbersome positioning, which not only increases the cost, but also greatly affects the positioning efficiency. Therefore, a multi-step punching positioning device for a machining center is proposed to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The utility model provides the following technical solutions: a multi-step drilling positioning device for a machining center, comprising a base 1, a fixing plate 2 is provided on the upper surface of the base 1, a mounting plate 3 is provided on the upper surface of the fixing plate 2, and a sleeve column 4 is provided on one side of the mounting plate 3.

[0024] In this embodiment, when it is necessary to perform positioning processing on a multi-step part, it can be performed by simply putting it on the sleeve column 4, which is convenient and quick.

[0025] In order to facilitate operation, a positioning clamping assembly for manual clamping operation is provided on the upper surface of the fixing plate 2 .

[0026] Among them, the positioning and clamping assembly includes a plurality of fixed frames 5 and slide seats 8, and the plurality of fixed frames 5 and slide seats 8 are vertically arranged on the upper surface of the fixed plate 2. The inner bearing of the fixed frame 5 is connected with a threaded rod 6, and the outer thread of the threaded rod 6 is connected with a threaded sleeve 7. A limit frame 9 is provided on one side of the threaded sleeve 7, and one side of the limit frame 9 is slidably connected with the slide seat 8, and a positioning fork 10 is provided on one side of the limit frame 9.

[0027] It can be understood that in this embodiment, the threaded rod 6 can be rotated to engage with the threaded sleeve 7, thereby driving the limit frame 9 and the positioning fork 10 to move, and finally effectively positioning and clamping the multi-step part.

[0028] In addition, a hand wheel is provided on one side of the threaded rod 6 , and the hand wheel is in the shape of a cylinder. By providing the hand wheel, it is convenient for an operator to rotate the threaded rod 6 .

[0029] In addition, a thread groove is provided on the inner side wall of the threaded sleeve 7 , and the thread groove is threadably matched with the thread strip on the outer side of the threaded rod 6 . By providing the thread groove, the threaded rod 6 can effectively make threaded contact with the threaded sleeve 7 .

[0030] It should also be noted in this embodiment that a slide groove is provided on the top of the slide seat 8, and the slide groove is adapted to the limit frame 9. By providing the slide groove and the limit frame 9, the threaded sleeve 7 can be effectively limited to prevent the threaded sleeve 7 from rotating in place.

[0031] It is also necessary to understand that the positioning fork 10 in the present embodiment is composed of a rod body and a fork body, one side of the rod body is connected to the limit frame 9, and a fork body is provided on the other side of the rod body away from the limit frame 9, and the shape of the fork body is a horizontally placed "U" font. By setting the fork body and its unique "U" font shape, multi-step parts such as disks can be effectively and firmly clamped.

[0032] The working principle of this embodiment is as follows:

[0033] The combination of the mounting plate 3 and the sleeve plate column 4 provides a preliminary positioning point for the part. When the operator needs to position the part, the operator manually rotates the threaded rod 6 with a hand wheel. Since the threaded rod 6 is adapted to the threaded groove opened inside the threaded sleeve 7, the rotation action causes the threaded sleeve 7 to move along the axial direction of the threaded rod 6. This movement is transmitted through the limit frame 9 connected to one side of the threaded sleeve 7. The sliding connection between the limit frame 9 and the slide seat 8 ensures smooth movement. Since a positioning fork 10 is connected to one side of the limit frame 9, its "U"-shaped fork body design can adapt to cylinders of different diameters, thereby achieving effective clamping of multi-step parts.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
