Technical Field

[0001] This utility model relates to the field of self-centering positioning structure technology, specifically a self-centering sheet metal drilling positioning structure. Background Technology

[0002] A self-centering positioning structure is a type of positioning fixture that uses the synchronous movement of symmetrically distributed clamping elements to center and limit the workpiece. It is commonly used in machining and other fields. A self-centering sheet metal drilling positioning structure is a fixture that limits the position of sheet metal parts. Its main function is to ensure the stability of the sheet metal parts during drilling.

[0003] However, existing self-centering sheet metal drilling and positioning structures have the following problems when used:

[0004] Since drilling of sheet metal parts generates waste liquid and solid waste, in order to avoid the waste from polluting the environment around the device and affecting its use, the device needs to collect the waste. However, the existing self-centering sheet metal drilling positioning structure is not convenient for collecting the waste, which easily pollutes the environment around the device and reduces its practicality.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing self-centering sheet metal drilling and positioning structure. Utility Model Content

[0006] The purpose of this utility model is to provide a self-centering sheet metal drilling and positioning structure to solve the problem mentioned in the background art that the existing self-centering sheet metal drilling and positioning structure is inconvenient to collect processing waste, which easily pollutes the environment around the device and reduces the practicality of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-centering sheet metal drilling and positioning structure, comprising a processing table and a dual-head servo motor. A square frame is fixedly connected to the edge of the upper surface of the processing table, and a dual-head servo motor is fixedly installed on the inner wall of the middle of the square frame. Both ends of the output shaft of the dual-head servo motor are fixedly fitted with transmission rods, and a square sleeve is fitted on the outer wall of the transmission rod. A support arm is fixedly connected to the outer wall of the front end of the square sleeve, and a clamp is fixedly installed at the end of the support arm. A drain hole is opened on the surface of the processing table on the side of the square frame, and a collection box is movably installed on the inner wall of the square frame. A support plate is fixedly installed on the upper inner wall of the collection box, and a filter cylinder is slidably installed on the inner wall of the support plate. The filter cylinder is located below the drain hole, and a limit mechanism is provided on the front of the collection box.

[0008] Preferably, the transmission rod and the square sleeve are threaded together, and the direction of the threads on the outer wall of the transmission rod is symmetrically distributed about the longitudinal central axis of the square frame.

[0009] Preferably, the square sleeve and the square frame form a sliding structure, and the fixture and the processing table are slidably arranged.

[0010] Preferably, both the collection box and the filter cartridge are slidably connected to the processing table.

[0011] Preferably, the limiting mechanism includes a knob, a sleeve, a positioning rod, a pull rope, and a spring. The knob is movably mounted on the front of the collection box, and a sleeve is fixedly connected to the surface of the collection box on the side of the knob.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a self-centering sheet metal drilling and positioning structure, including a processing table 1, a square frame 2, a dual-head servo motor 3, a transmission rod 4, a square sleeve 5, a support arm 6, a clamp 7, a drain hole 8, a collection box 9, a support plate 10, a filter cartridge 11, a limiting mechanism 12, a knob 1201, a rod sleeve 1202, a positioning rod 1203, a pull rope 1204, a spring 1205, and a clamping plate 13. A square frame 2 is fixedly connected to the edge of the upper surface of the processing table 1, and a dual-head servo motor 3 is fixedly installed on the inner wall of the middle of the square frame 2. Both ends of the output shaft of motor 3 are fixed with transmission rods 4, and the outer wall of the transmission rods 4 is fitted with a square sleeve 5. At the same time, the outer wall of the front end of the square sleeve 5 is fixedly connected with a support arm 6, and the end of the support arm 6 is fixedly installed with a clamp 7. The surface of the processing table 1 on the side of the square frame 2 is provided with a leakage hole 8, and a collection box 9 is movably installed on the inner wall of the square frame 2. A support plate 10 is fixedly installed on the upper inner wall of the collection box 9, and a filter cylinder 11 is slidably installed on the inner wall of the support plate 10. The filter cylinder 11 is located below the leakage hole 8, and a limit mechanism 12 is provided on the front of the collection box 9.

[0024] The transmission rod 4 and the square sleeve 5 are threadedly connected, and the direction of the thread on the outer wall of the transmission rod 4 is symmetrically distributed about the longitudinal central axis of the square frame 2, so that when the dual-head servo motor 3 drives the transmission rod 4 to rotate, the square sleeve 5 moves simultaneously towards or away from the transmission rod 4.

[0025] The square sleeve 5 and the square frame 2 form a sliding structure. The fixture 7 and the processing table 1 are slidably set, which facilitates the stable sliding of the square sleeve 5 relative to the square frame 2, thereby driving the support arm 6 and making the fixture 7 slide relative to the processing table 1.

[0026] Both the collection box 9 and the filter cartridge 11 are slidably connected to the processing table 1, which makes it easy for the user to move the collection box 9 to disassemble and assemble it. As the collection box 9 moves, it drives the filter cartridge 11 to slide relative to the processing table 1.

[0027] The limiting mechanism 12 includes a knob 1201, a sleeve 1202, a positioning rod 1203, a pull rope 1204, and a spring 1205. The knob 1201 is movably mounted on the front of the collection box 9, and the sleeve 1202 is fixedly connected to the surface of the collection box 9 on the side of the knob 1201. The positioning rod 1203 is movably mounted on the inner wall of the sleeve 1202, and the end face of the positioning rod 1203 is connected to the outer wall of the knob 1201 through the pull rope 1204. A clamping plate 13 is fixedly mounted on the outer wall of the processing table 1 on the side of the positioning rod 1203, so as to limit the collection box 9 through the limiting mechanism 12, thereby ensuring the working stability of the collection box 9.

[0028] The knob 1201 and the collection box 9 form a rotating structure, which makes it easy for the user to rotate the knob 1201.

[0029] The positioning rod 1203 is slidably connected to the rod sleeve 1202 and the clamping plate 13 respectively, and the end face of the positioning rod 1203 is connected to the inner wall of the end of the rod sleeve 1202 through the spring 1205. This facilitates the rotation of the knob 1201, which winds up the pull rope 1204, causing the pull rope 1204 to move the positioning rod 1203 relative to the rod sleeve 1202, thereby allowing the positioning rod 1203 to disengage from the clamping plate 13. This makes it easier for the user to move the collection box 9. At the same time, the spring 1205 provides elastic support for the positioning rod 1203.

[0030] Working principle: When using this self-centering sheet metal drilling and positioning structure, firstly as follows... Figure 1-5As shown, the user inserts the filter cartridge 11 into the support plate 10. Then, the user turns the knob 1201 relative to the collection box 9. Next, the knob 1201 winds up the pull rope 1204, which in turn pulls the positioning rod 1203 relative to the rod sleeve 1202. Simultaneously, the positioning rod 1203 compresses the spring 1205, causing it to deform. The user then moves the collection box 9 into the processing table 1. Next, the user releases the knob 1201, at which point the spring 1205 returns to its original position, pushing the positioning rod 1203 to move and insert it into the clamping plate 13, thus completing the installation of the collection box 9 and the filter cartridge 11. The user then places the sheet metal part to be drilled on the processing table 1 and starts the double-sided... First, a head servo motor 3 is used. Next, the dual head servo motors 3 drive the transmission rod 4 to rotate simultaneously. Then, the square sleeve 5 slides along the transmission rod 4 and relative to the square frame 2. At this time, the square sleeve 5 drives the support arm 6 and the clamp 7 to move towards each other simultaneously. Then, the clamp 7 moves and fits against both sides of the sheet metal part, thereby completing the self-centering positioning of the sheet metal part. Then, when the user drills the sheet metal part, the waste liquid and solid waste fall into the filter cartridge 11 through the leakage hole 8. Then, the waste liquid passes through the filter cartridge 11 and falls into the collection box 9, thereby completing the collection of processing waste and also performing solid-liquid separation of processing waste. Therefore, the device is convenient for collecting processing waste, thereby avoiding the pollution of the surrounding environment by processing waste, thus improving the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
