Description

TECHNICAL FIELD

[0001] The present application relates to the field of component installation, in particular to a foldable dotting positioning tool. BACKGROUND

[0002] In some component installation processes, for some components installed by screwing or riveting, such as various control boxes, explosion-proof boxes, alarms, loudspeakers, controllers, etc., a bench worker needs to process through holes or threaded holes on the installation surface on site. There are two conventional processing methods. One is to determine the installation hole position on the corresponding installation surface by measuring, marking a cross line, and dotting according to the installation hole size drawing or the measured installation hole position of the actual object (generally, there are 4-6 installation hole positions for a single component), and finally processing through holes or threaded holes at the position. This traditional cross line marking and dotting method requires at least two measurements of the position size for each hole position in the single component installation process, i.e., one measurement for the X-axis coordinate and one measurement for the Y-axis coordinate. When installing holes in batches, repeated measurements and positioning are required on each parent component, which is a large amount of manual measurement work and has a large measurement error, resulting in extremely low processing efficiency. The other method is to make special hole position tooling according to the installation hole position of the assembled component, and then use the special tooling to mark the hole position on the installation surface. This method has the disadvantage that special tooling needs to be made for each different hole position of the component, which will result in a large number of tooling styles and inconvenient management. SUMMARY

[0003] The present application aims to provide a foldable dotting positioning tool that can achieve fast and efficient dotting positioning on the installation surface of each component through only one measurement and positioning, and is suitable for the installation hole process of batch component assembly. For the installation hole processing of different components, only the position of the movable plate needs to be adjusted, and the tool is suitable for a wide range of components.

[0026] Specific use steps

[0027] The application will be further described below by specific examples, but it should be understood that the steps are used only for more detailed specific description, and should not be understood as limiting the application in any form.

[0028] In combination Figures 1-8 , the embodiment provides a foldable dotting positioning tool, mainly comprising two sections of main tracks 1, connecting blocks 2, reference plates 3, movable plates 4, locking plates 5, locking screw assemblies 6 and central punches 7. The two sections of main tracks 1 are respectively rotationally connected with the connecting blocks 2, and two groups of movable plates 4 are respectively slidably connected with the two sections of main tracks 1. The reference plate 3 is rotationally installed at the end of one section of main track 1 and can be retracted into the main track 1 by rotation. The central punch 7 passes through the end of each group of movable plates to perform dotting positioning. The locking device is used to fix the two sections of main tracks 1. The two sections of main tracks can be unfolded or folded by stretching and rotating actions. The locking function of the main tracks 1 in the unfolded and folded states is realized by the locking plates 5. The reference plate 3 can be retracted into the main track 1 by rotation and translation, and occupies a small space. The movable plates 4 can be adjusted in a certain range by the track slots of the main tracks 1 and the long slots of the movable plates 4. The locking screw assemblies 6 can lock the movable plates. Finally, the central punch 7 is used to complete dotting positioning through the positioning holes on the movable plates 4.

[0029] The main track 1 has a "T" shaped slot inside, the head of the locking screw assembly 6 can move inside, and there are four fixed columns on the inside, which can be connected with the connecting block 2, and there are fixed columns on the outside for use when the locking plate 5 is locked. The two sections of main tracks can realize unfolding or folding function by stretching and rotating actions.

[0030] The connecting block 2 connects the two main tracks 1, the middle "gourd-shaped" special-shaped hole can realize the positioning and moving function of the pin shaft at the corresponding position of the main track 1, the two sides "L" shaped through slot provides space for the rotation of the main track 1, and the internal T-shaped slot structure can realize the movement of the movable plate 4 between the two sections of main tracks.

[0031] The reference plate 3 has a through long slot and is fixed on the main track 1 by screws (standard parts). The reference plate 3 can be unfolded or retracted into the main track 1 by rotation and translation, and occupies a small space.

[0032] There are four movable plates, which are divided into two groups, and each group of movable plates is connected by a locking screw assembly 6. Each group of movable plates can realize relative movement or rotation between the movable plates by the long slots of the movable plates. The two groups can move in the main track, and finally the four positioning holes can be fixed at any position in a certain range. The diameter of the positioning hole matches the outer diameter of the matched central punch 7, so that the central punch 7 can move vertically to the movable plate 4 in the positioning hole. In the unfolded state of the main track 1, the movable plate 4 can move at any position between the two main tracks 1, and at the same time, the long slots of the movable plate 4 realize translation or rotation, and finally realize positioning of the positioning hole at any position in the X-axis and Y-axis directions in a certain range.

[0033] After the locking plate is rotated, the locking plate is matched with the two sides of the main track 1, and the locking or opening state of the main track 1 is completed by rotating the locking plate 5 clockwise or counterclockwise.

[0034] The locking screw assembly 6 is composed of a special bolt 6-3, a nut 6-1 and a gasket 6-2, and can move in the groove of the main track 1 and lock the movable plate 4.

[0035] The center punch 7 is a cylindrical shape, one end of which is a sharp end, which directly contacts the workpiece to realize dot positioning, and the outer diameter of which matches the positioning hole diameter of the movable plate 4.

[0036] The use process of the foldable dot positioning tool includes:

[0037] 1. As Figure 9 , the main track 1 is in the initial state of closed state, the locking plate 5 is rotated upward to make the locking plate 5 in the open state, and then the main track 1 is rotated to the horizontal state.

[0038] 2. As Figure 10 , the two sections of the main track are translated to the middle, the locking plate 5 is rotated to the closed state, the connecting nut of the reference plate 3 is loosened, and the reference plate 3 is completely pulled out of the main track 1.

[0039] 3. As Figure 11 , the reference plate 3 is rotated to be perpendicular to the main track 1, then it is translated to the target position according to the required reference size, and finally the connecting nut of the reference plate 3 is tightened. The nut of the locking screw assembly 6 is loosened, the movable plate is translated to the required target position, and then the nut is tightened again.

[0040] 4. The center punch 7 is used to complete dot positioning at the target position through the positioning hole of the movable plate 4.

[0041] 5. After use, reverse operation is performed to return the movable plate 4 and the reference plate 3 to the original position, fold the main track 1, and rotate the locking plate 5 to the locking position.

[0042] The tool has the advantages of simple structure, convenient use, small volume after folding, and convenient carrying; after unfolding, the tool is suitable for a wide range of hole spacing, and in the process of batch installation of parts or life devices, only one measurement and positioning is required, the position of the movable plate 4 is determined, and then the fast and efficient dot positioning and marking function can be realized on the installation surface of each part. If other parts need to be marked at different hole positions, only the position of the movable plate needs to be adjusted, and there is no need to re-draw a line or re-produce a special hole marking tool.

[0043] The above describes in detail the foldable hole positioning tool, and the principle and use steps of the application are described. The above steps are only used to help understand the method and core idea of the application. Meanwhile, for those skilled in the art, the specific implementation and application range will be changed according to the idea of the application. In summary, the content of the specification should not be understood as a limitation of the application.
