Description

Technical Field

[0001] The present invention relates to the technical field of drilling processing, and particularly to a rapid positioning tooling assembly for drilling of components and a using method thereof. Background Art

[0002] In the field of machining production, it is often necessary to drill some steel structure components. For products such as H-shaped components or box-shaped components, due to their relatively large volume, the determination of the drilling positions directly relates to the accuracy of drilling processing.

[0003] The traditional drilling positioning method is to directly use a pen ruler to draw lines on these components to show the corresponding drilling positions. In this way, the production efficiency is very low, the labor intensity of workers is also relatively large, it cannot meet mass production, and the drilling positions are not accurate enough. If a tooling fixture is used to clamp these components to position the drilling positions, it is necessary to spend a large cost to design a large-sized positioning fixture body. It is not only not flexible enough to use, but also different fixture bodies need to be designed for different components. Moreover, manufacturing multiple sets of fixture bodies will increase the occupied space. Summary of the Invention

[0004] The purpose of the present invention is to provide a rapid positioning tooling assembly for drilling of components and a using method thereof, which can quickly and accurately position the drilling positions of components, greatly reduce the labor intensity of workers during mass production, and is flexible to use and occupies a small space.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A rapid positioning tooling assembly for drilling of components includes a positioning member, a magnet, two wedge blocks, a template that matches the surface of the component to be drilled and has a plurality of hole positions, and a plurality of pins that match the hole positions. The positioning member includes a horizontal plate for leaning against the top surface of the workpiece and a vertical plate for abutting against the surface of the workpiece to be drilled. A plurality of positioning holes are formed in the vertical plate.

[0006] Preferably, the pin is a wedge-shaped pin.

[0007] More preferably, the number of the pins is two.

[0008] More preferably, the number of the positioning holes is at least two.

[0009] More preferably, the horizontal plate and the vertical plate are perpendicularly connected to form the L-shaped positioning member.

[0010] Or preferably, a transition plate is perpendicularly connected to the horizontal plate, the vertical plate is vertically arranged and fixedly connected to the inner wall surface of the transition plate, and a gap is provided between the horizontal plate and the vertical plate.

[0011] In addition, the present invention also provides a method for using the above-mentioned rapid positioning tooling assembly for drilling components, which includes the following steps:

[0012] S1, place the cross plate of the positioning member against the top surface of the workpiece, and make the vertical plate abut against the surface of the workpiece to be drilled.

[0013] S2, adjust the side edge of the vertical plate to align it with the side edge of the surface of the workpiece to be drilled, and then use the magnet to suck the cross plate and the top surface of the workpiece to each other.

[0014] S3, use a drilling tool to drill the workpiece from the position of the positioning hole, so as to form a plurality of formed holes on the surface of the workpiece to be drilled.

[0015] S4, remove the positioning member and the magnet, place the template against the surface of the workpiece to be drilled and align them, and then use pins to insert into the hole positions on the template and the corresponding formed holes on the workpiece at the same time. By using two pins to respectively position a group of corresponding hole positions and formed holes, the template can be positioned on the workpiece, and the hole positions on the template can be aligned with the remaining parts to be drilled on the surface of the workpiece to be drilled.

[0016] Preferably, in step S2, use two wedge blocks to insert between the cross plate and the top surface of the workpiece, so as to adjust the height position of the positioning hole, and then the magnet can suck the vertical plate and the workpiece to each other or suck the transition plate and the workpiece to each other.

[0017] The beneficial effects of the present invention are as follows: at least two drilling parts can be pre-positioned on the surface of the workpiece to be drilled through the positioning member and the magnet, and then the holes at these parts are processed and the positioning member and the magnet are removed. Since the template matches the surface of the workpiece to be drilled and can be used universally on the same kind of workpiece, after two formed holes have been processed on a workpiece, the template can be placed against the surface of the workpiece to be drilled, and then pins are used to insert into the hole positions on the template and the corresponding formed holes on the workpiece. The two pins position two groups of hole positions and formed holes, and the whole template can be positioned and connected to the surface of the workpiece to be drilled. For subsequent processing work, only drill holes in sequence according to the hole positions on the template. Using this set of tooling assembly can quickly and accurately position the drilling positions of the components, which can greatly reduce the labor intensity of workers during mass production. And the positioning plate can be applied to different components, with flexible use and small volume. Since the template is in the shape of a plate, it also occupies less space.

[0034] Embodiment 1

[0035] As shown Figures 1-5 in the figure, a rapid positioning tooling assembly for drilling of components includes a positioning member 1, a magnet 2, two wedge blocks 3, a template 4 that matches the surface of the component to be drilled and has multiple hole positions, and multiple pins 5 that match the hole positions. The positioning member 1 includes a cross plate 1a for resting on the top surface of the workpiece and a vertical plate 1b for abutting against the surface of the workpiece to be drilled. A plurality of positioning holes 1c are formed on the vertical plate 1b.

[0036] Preferably, the pin 5 is a wedge-shaped pin, and the number of pins 5 is two.

[0037] More preferably, the number of positioning holes 1c is at least two.

[0038] More preferably, the cross plate 1a and the vertical plate 1b are perpendicularly connected to form an L-shaped positioning member 1.

[0039] In addition, this embodiment also provides a method for using the above rapid positioning tooling assembly for drilling of components, which specifically includes the following steps:

[0040] S1. Rest the cross plate 1a of the positioning member 1 on the top surface of the workpiece, and make the vertical plate 1a abut against the surface of the workpiece to be drilled.

[0041] S2. Adjust the side edge of the vertical plate 1a to align it with the side edge of the surface of the workpiece to be drilled, and then use the magnet 2 to suck the cross plate 1a and the top surface of the workpiece to each other.

[0042] S3. Use a drilling tool to drill the workpiece from the position of the positioning hole 1c, so as to form a plurality of formed holes 6 on the surface of the workpiece to be drilled.

[0043] S4. Remove the positioning member 1 and the magnet 2, place the template 4 against the surface of the workpiece to be drilled and align the two, then use the pins 5 to insert into the hole positions on the template 4 and the corresponding formed holes 6 on the workpiece at the same time. One group of corresponding hole positions and formed holes 6 are positioned by the two pins 5 respectively, so that the template 4 can be positioned on the workpiece, and the hole positions on the template 4 are aligned with the remaining parts to be drilled on the surface of the workpiece to be drilled.

[0044] The rapid positioning tooling for component drilling provided by the above embodiment can pre-position at least two drilling parts on the surface of the workpiece to be drilled (such as Figure 1 the box-shaped component 7 shown) through the positioning member 1 and the magnet 2, then process the holes at these parts and remove the positioning member 1 and the magnet 2. Since the template 4 matches the surface of the workpiece to be drilled and can be used universally on the same kind of workpiece, after two formed holes 6 have been processed on a workpiece, the template 4 can be placed against the surface of the workpiece to be drilled, and then the pins 5 are used to insert into the hole positions of the template 4 and the corresponding formed holes 6 on the workpiece. The two pins 5 position two groups of hole positions and formed holes 6, and the whole template 4 can be positioned and connected to the surface of the workpiece to be drilled. For subsequent processing work, drilling can be carried out in sequence facing the hole positions on the template 4.

[0045] Using this set of tooling components can quickly and accurately position the drilling positions of the components. During mass production, the labor intensity of workers can be greatly reduced to a large extent. And the positioning plate 1 can be applied to different components, is flexible in use, small in size, and the template 4 also occupies less space because it is in a plate shape.

[0046] It should be noted that for some types of components, the distance between the hole positions at the top edge of the surface to be drilled and the side edge of the component is fixed, that is, the distances between the drilling positions to be drilled of various components and the edges of their respective components are the same. Moreover, the distances between the hole positions are also the same (the difference may only lie in the different areas of the surface to be drilled). Therefore, the positioning plate 1 can be used universally on various components. Then for those skilled in the art, when designing the position of the positioning holes 1c in the above embodiment, it is only necessary to ensure that the distance between the positioning holes 1c at the top edge of the vertical plate 1b and the side edge of the vertical plate 1b is within a specified size.

[0047] Preferably, in the method provided in this embodiment, the first processing part can also be marked by using a pen ruler to draw a line at the top edge of the surface of the workpiece to be drilled. In this way, when installing the positioning plate 1, the position of the positioning holes 1c can be finely adjusted with reference to the marked part, so as to further improve the positioning accuracy and reduce the deviation. If there is a deviation between the positioning holes 1c on the vertical plate 1b and the marked part, in addition to moving the positioning plate 1 left and right, two wedge-shaped blocks 3 can also be used to insert between the cross plate 1a and the top surface of the workpiece from both sides of the cross plate 1a (such asFigure 4 As shown in the figure, the height position of the positioning hole 1c is adjusted, and then the vertical plate 1b and the workpiece are attracted to each other by the magnet 2 (enough space can be left on the vertical plate 1b except for the positions of the necessary two positioning holes 1c as long as the necessary two positioning holes 1c are not blocked), so that the positioning tooling assembly can better adapt to the workpiece.

[0048] Embodiment 2

[0049] As Figures 6-8 shown, the difference between this embodiment and Embodiment 1 lies only in the structure of the positioning plate 1. Specifically, for the positioning plate 1 of this embodiment, a transition plate 1d is vertically connected to the horizontal plate 1a, and the vertical plate 1b is vertical and fixedly connected to the inner wall surface of the transition plate 1d. There is a gap between the horizontal plate 1a and the vertical plate 1b. The positioning plate 1 with this structure is to better adapt to the H-shaped member. As Figure 7 shown, since the drilling surface to be machined of the H-shaped member is located in the middle of the inner side, after using the positioning plate 1 to position on the workpiece, the transition plate 1d can abut against the front end of the H-shaped member, and the vertical plate 1b can extend into the middle of the H-shaped member and abut against the drilling surface to be machined. Therefore, the subsequent drilling processing steps are the same as those in Embodiment 1.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.

[0051] In order to make it easier for those of ordinary skill in the art to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified. And for the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present invention.
