Description

Technical Field

[0001] This application relates to the field of sheet metal boring technology, and in particular to a sheet metal boring positioning device. Background Technology

[0002] Boring is a machining process used to further enlarge the diameter of forged holes, punched holes, drilled holes, and cast holes. During boring, a fixture is required to hold the workpiece in place.

[0003] According to announcement number CN214518963U, a multi-clamping tooling for boring sheet metal parts is disclosed. This technology discloses a technical solution that includes "a base, a rotating disk rotatably connected to the upper surface of the base, a drive motor connected to the rotating disk for driving its rotation; a plurality of clamping stations arranged sequentially along the circumference of the rotating disk; at least two positioning rods fixedly provided at each clamping station that can cooperate with the mounting holes located on the bottom plate of the sheet metal part; a clamping block that can abut against the upper surface of the bottom plate of the sheet metal part slidingly in the vertical direction at each clamping station; and a drive component for driving the clamping block to move between the clamping block and the rotating disk." This solution has the technical effect of increasing the number of sheet metal parts that can be clamped at one time by cooperating with the drive motor and the rotating disk, reducing the number of times the machine tool is started and stopped, thereby improving the processing efficiency of sheet metal parts.

[0004] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0005] First, the main body of the above-mentioned device is a base, but the top surface of the base does not have a chip removal structure, and the more delicate mounting blocks and other structures are exposed. This may cause some iron filings to get stuck in the groove during use, which will affect its subsequent use, reduce its service life, and increase the maintenance frequency.

[0006] Secondly, when the above-mentioned device fixes the sheet metal parts, some sheet metal parts have irregular shapes, resulting in their sides being sloping. Since the device clamps the sheet metal parts in a linear motion, the clamping effect on some sheet metal parts is not good.

[0007] To address the aforementioned problems, the inventors proposed a sheet metal boring and positioning device to solve these issues. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-6As shown, this utility model provides a sheet metal boring and positioning device, including a support platform 1. The support platform 1 serves as a support component and can support other structures of the device. A support mechanism 2 is fixedly installed on the top surface of the support platform 1. The support mechanism 2 is fixedly connected to the support platform 1 by bolts and can be disassembled when necessary. Multiple first positioning mechanisms 3 are provided on the top surface of the support mechanism 2 for mutual cooperation. The multiple first positioning mechanisms 3 can cooperate to position the side of the sheet metal part. At the same time, the first positioning mechanisms 3 can be adjusted to position some irregularly shaped sheet metal parts. A second positioning mechanism 4 is fixedly installed on the top surface of each of the multiple first positioning mechanisms 3. The second positioning mechanism 4 can position the sheet metal part in the vertical direction.

[0025] The support mechanism 2 includes a fixed plate 21, which is fixedly installed inside the top surface of the support platform 1. The bottom surface of the fixed plate 21 penetrates the support platform 1, thus facilitating chip removal. A chip removal port 23 is provided in the middle of the top surface of the fixed plate 21. The chip removal port 23 is through-hole, which can discharge iron chips. Multiple guide grooves 22 are provided on the upper surface of the fixed plate 21. The multiple guide grooves 22 are distributed on the side of the chip removal port 23, and one end of the multiple guide grooves 22 is connected to the chip removal port 23. Through the guide grooves 22, it is easier to clean the iron chips after the operation is completed, thereby improving the cleaning efficiency. The cross-section of the multiple guide grooves 22 is trapezoidal, which allows the iron chips to enter the interior of the guide grooves 22 better. The multiple guide grooves 22 are distributed in a cross shape, which can process iron chips from multiple directions on the top surface of the fixed plate 21.

[0026] A support frame 24 is fixedly installed on the bottom surface of the fixed plate 21. The support frame 24 is a support component that can support the pull-out box 25. At the same time, it is in a damped sliding connection with the pull-out box 25, so that the pull-out box 25 has a certain resistance. The pull-out box 25 is slidably installed inside the support frame 24. The pull-out box 25 is a box structure that can collect iron filings. The pull-out box 25 is located directly below the chip discharge port 23, making it easier to collect iron filings.

[0027] The first positioning mechanism 3 includes a positioning plate 32, which is integrally formed from a plate body and a block structure. It can slide on the top surface of the fixed plate 21 and simultaneously drive the positioning block 31 to move. The positioning plate 32 is slidably installed on the top surface of the fixed plate 21, allowing it to slide and thus position the sides of the sheet metal parts. A positioning block 31 is fixedly installed on one side of the positioning plate 32, and a rubber pad is provided on the side of the positioning block 31 away from the positioning plate 32. This can position the sheet metal parts and prevent them from being damaged.

[0028] Both sides of the positioning plate 32 are provided with sliding grooves 34. The sliding grooves 34 have a certain length and can allow the fastening bolts 33 to slide inside. The fastening bolts 33 are movably inserted into the two sliding grooves 34. As a prior art, the fastening bolts 33 can move together with the positioning plate 32 and fix the positioning plate 32. The top surface of the fixing plate 21 is provided with multiple inner grooves 30. The fastening nuts 331 are slidably installed inside the multiple inner grooves 30. The cross-sectional shape of the inner groove 30 is "convex". The fastening nuts 331 slide inside the inner grooves 30, allowing the fastening nuts 331 to slide and preventing them from rotating, so as to better cooperate with the fastening bolts 33 for fixation. The bottom ends of the multiple fastening bolts 33 movably pass through the inner grooves 30 and are threaded into the fastening nuts 331. When the fastening bolts 33 are rotated, the fastening nuts 331 can be lifted through the thread structure, thereby locking the positioning plate 32 and the fixing plate 21 together.

[0029] Both sides of the inner groove 30 are fixedly installed with accordion-style protective plates 35. The accordion-style protective plates 35 can extend and retract, thereby protecting the inner groove 30 and its internal structure. The opposite side of the two accordion-style protective plates 35 is in contact with the outer surface of the fastening bolt 33, so that it can extend and retract when the fastening bolt 33 moves, thereby always protecting the internal structure of the inner groove 30. The slide 34 is set perpendicular to the inner groove 30. Through the slide 34, the positioning plate 32 can rotate to a certain extent, thereby positioning some irregularly shaped sheet metal parts.

[0030] The second positioning mechanism 4 includes a connecting plate 46, which serves as a support and is fixedly installed on the top surface of the positioning plate 32. By welding it to the positioning plate 32, it can prevent the positioning plate from falling off. An adjusting plate 45 is fixedly installed on the top surface of the connecting plate 46, which serves as a support and can support the positioning rod 47 and allow it to rotate. The positioning rod 47 is rotatably installed on one side of the top surface of the adjusting plate 45. A round rod 48 is fixedly installed on the bottom surface of the middle part of the positioning rod 47. The round rod 48 is slidably installed on one side of the top surface of the adjusting plate 45. An arc-shaped adjusting groove 44 is opened on one side of the top surface of the adjusting plate 45. The round rod 48 is slidably installed inside the adjusting groove 44. The adjusting groove 44 is arc-shaped, and its center is located at the connection between the positioning rod 47 and the adjusting plate 45. At the same time, its outer surface is provided with a scale to adjust the angle of the positioning rod 47, thereby adapting to different sheet metal parts.

[0031] A lead screw 41 is threaded into the top surface of the end of the positioning rod 47 away from the connecting plate 46. The lead screw 41 is existing technology and can drive the limiting plate 43 to move. The bottom end of the lead screw 41 is rotatably mounted with the limiting plate 43. The limiting plate 43 can position the sheet metal part vertically, thereby preventing it from jumping due to impact. Limiting rods 42 are fixedly installed on both sides of the top surface of the limiting plate 43. The top ends of the limiting rods 42 are slidably connected to the positioning rod 47. Two support plates are provided at one end of the positioning rod 47. The two limiting rods 42 slide through the two support plates respectively. The limiting rods 42 can limit the positioning rod 47, thereby preventing it from rotating.

[0032] Working principle: First, the device is supported by the support platform 1. Then, the sheet metal part is placed on the top surface of the fixed plate 21 of the support mechanism 2. Then, the first positioning mechanism 3 is activated, and multiple positioning plates 32 are slid to move multiple positioning blocks 31 close to and contact the side of the sheet metal part for fixing. When it is necessary to adapt to the inclined surface, the positioning plates 32 can be rotated to tilt the positioning blocks 31. At the same time, the fastening bolts 33 on both sides will slide inside the slide groove 34, so that the positioning blocks 31 fit the inclined surface. Then, the fastening bolts 33 are rotated with a tool to make the fastening bolts 33 engage with the fastening nuts 331 inside the inner groove 30 through the threads, thereby fixing the positioning plate 32 in a suitable position on the top surface of the fixed plate 21. Meanwhile, the bellows-type protective plate 35 can prevent iron filings from entering the inner groove 30.

[0033] Then, using the second positioning mechanism 4, the positioning rod 47 is rotated, causing the positioning rod 47 to rotate on the top surface of the adjusting plate 45, and driving the round rod 48 to slide with damping inside the adjusting groove 44, thereby driving the limiting plate 43 to be located on the top surface of the sheet metal part. Then, the lead screw 41 is rotated, causing the lead screw 41 to drive the limiting plate 43 to descend. The limiting plate 43 is limited by the limiting rod 42, thereby descending vertically and fixing the top surface of the sheet metal part.

[0034] When it is necessary to discharge iron filings, the iron filings can be swept into multiple guide grooves 22 and moved into the chip discharge port 23 through the guide grooves 22, so that the iron filings can enter the pull-out box 25 for collection.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
