Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical process equipment, and relates to the positioning of machining holes of cavity-shaped workpieces, and specifically relates to a positioning guide tool and a method for using the same. Background Art

[0002] A cavity-shaped workpiece needs to have a hole machined or a positioning point marked on the outer wall of the cavity. The hole or point on the outer wall needs to be coaxial with the hole on the inner wall (or there is a relative position requirement). However, since the hole on the workpiece is on the inner wall of the cavity, the space is limited and the operating tool cannot be directly operated. Even if it can be operated, it is difficult to ensure that the hole or point on the outer wall is completely coaxial with the hole on the inner wall.

[0003] In actual operation, operators often manually mark the outer wall of the hole to be opened based on their experience. Such operations often have large errors and are difficult to meet high-precision requirements. The lack of positioning accuracy will directly affect the quality of the product. Summary of the Invention

[0004] In response to the defects or improvement needs of the above-mentioned prior art, the present invention provides a positioning and guiding tool and a method of using the same, which guides the blind hole position of the inner wall to the guide hole of the guide plate through a positioning pin, a positioning plate, and a guide plate.

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0039] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, in the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0040] like Figure 1-4 As shown, the present invention provides a positioning and guiding tool, including a positioning plate, an adjustment plate and a guide plate. The shapes of the positioning plate and the guide plate are consistent. The adjustment plate is used to adjust the gap between the positioning plate and the guide plate so that it is equivalent to the wall thickness of the processing part. At the same time, the adjustment plate is also a fixed bracket for installing the guide plate, which can ensure that the relative positions of the positioning plate and the guide plate are fixed, so that the positioning plate, the adjustment plate and the guide plate can be installed reliably.

[0041] The positioning plate, adjustment plate, and guide plate are secured together from top to bottom by a plurality of fastening screws, which extend sequentially through the guide plate, adjustment plate, and positioning plate. In this embodiment, the locking members are two fastening screws, namely a first fastening screw and a second fastening screw. In another embodiment, the locking members are bolts and nuts, which cooperate to securely connect the positioning plate, adjustment plate, and guide plate.

[0042] The positioning plate, the adjustment plate and the guide plate are provided with a plurality of coaxial positioning holes, and a plurality of positioning pieces matching the positioning holes pass through the positioning holes so that the positioning plate, the adjustment plate and the guide plate do not move during use.

[0043] In this embodiment, a first locating hole is defined on one side of the locating plate. A first locating pin is provided to match the first locating hole. The first locating pin extends through the first locating hole and into a blind hole in the workpiece, abutting against the workpiece. The diameters of the first locating pin and the first locating hole can be designed based on the diameter of the workpiece's blind hole, allowing them to be used in a variety of blind holes. Simultaneously, a guide hole coaxial with the first locating hole is defined on the guide plate. This allows tools such as a drill, punch, or marker to pass through the guide hole to machine a hole or mark a locating point on the outer wall of the workpiece cavity, ensuring that the hole or locating point on the outer wall is coaxial with the inner wall hole (or that the relative position meets design requirements). Second and third locating holes are also coaxially defined on the locating plate, adjustment plate, and guide plate. The second and third locating pins, which match the second and third locating holes, extend from top to bottom through the second and third locating holes and penetrate the locating plate and guide plate. A first fastening screw and a second fastening screw are positioned between the second and third locating pins. The transversely arranged fastening screws and the longitudinally arranged locating pins ensure that the entire fixture is securely connected and prevents displacement. Among them, the length of the adjustment plate is suitable to ensure that the guide plate is reliably installed without affecting the placement of the workpiece. In this embodiment, the length of the adjustment plate is half the length of the guide plate, and the first fastening screw, the second fastening screw and the third positioning pin pass through the adjustment plate; in another embodiment, the length of the adjustment plate extends to the second positioning pin, so that the first fastening screw, the second fastening screw, the second positioning pin and the third positioning pin all pass through the adjustment plate.

[0044] like Figure 5-8 As shown, the positioning plate and the guide plate can be designed as a rectangular plate structure according to the shape of the workpiece, or a Z-shaped structure to ensure that the workpiece can be placed in the space on one side of the first positioning hole and the guide through hole.

[0045] The method for using the positioning guide tool of this embodiment includes the following steps:

[0046] S1. Decompose the positioning guide fixture fastening screws and install the positioning member on the positioning plate to form a positioning plate assembly;

[0047] S2. The positioning plate assembly is mounted on the workpiece, and the blind hole of the inner wall of the workpiece is positioned with a first positioning pin;

[0048] S3. Install the adjustment plate. The thickness of the adjustment plate is h, h = h1 + h2, where h1 is the wall thickness of the workpiece to be processed, and h2 is 0-0.5mm depending on the workpiece material.

[0049] S4. Install the guide plate, which is positioned by the second and third positioning pins;

[0050] S5. Install the fastening screws to secure the guide plate to the positioning plate.

[0051] S6. Processing holes on the outer wall of the workpiece or defining positioning points on the outer wall of the workpiece through the guide through holes on the guide plate.

[0052] S7. After the operation is completed, remove the fastening screws, disassemble the tooling, and separate the positioning plate assembly from the workpiece;

[0053] S8. Assemble the tooling, secure it with screws, and return it to the warehouse for safekeeping.

[0054] It is easy for those skilled in the art to understand that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
