Description

Technical Field

[0001] This application relates to the field of steel structure processing technology, specifically a steel structure hole expansion and positioning mechanism. Background Technology

[0002] Steel structures are widely used in modern architecture and engineering, especially in large-scale projects where the assembly and connection of steel structures are crucial. To ensure the precise installation of steel structures, hole enlargement and positioning has become one of the key technologies.

[0003] Traditional steel structure hole enlargement usually relies on manual calibration and mechanical equipment operation, lacking calibration auxiliary devices. This not only increases the labor intensity of workers, but also easily leads to hole position errors due to improper operation, thereby affecting the overall stability and safety of the steel structure. It cannot flexibly adjust or adapt to the needs of different hole positions, and errors may occur during the hole enlargement process, resulting in inaccurate hole positions or irregular hole shapes, affecting the subsequent assembly accuracy.

[0004] Therefore, this application provides a steel structure hole-expanding positioning mechanism to solve the above problems. Utility Model Content

[0005] This application provides a steel structure hole enlargement and positioning mechanism, which aims to solve the problem mentioned in the background art that steel structure hole enlargement usually relies on manual calibration and mechanical equipment operation. Due to the lack of calibration auxiliary devices, improper operation can easily lead to hole position errors.

[0006] To achieve the above objectives, this application provides the following technical solution: a steel structure hole enlargement and positioning mechanism, including a positioning component disposed on a steel structure component;

[0007] The positioning assembly includes two relatively distributed fixed plates and a limiting rod fixedly installed between the two fixed plates. Clamping plates are symmetrically sleeved on the limiting rod. A bidirectional lead screw is threaded into the clamping plate. The bidirectional lead screw is rotatably connected between the two fixed plates, and one end of the bidirectional lead screw passes through one of the fixed plates. A torsion wheel is fixedly installed at the end of the bidirectional lead screw that passes through the fixed plate. A slide seat is provided between the two clamping plates and sleeved on the limiting rod. A perforated plate for positioning the opening is provided at the lower end of the slide seat. A handle is fixedly installed at the lower end of the fixed plate.

[0008] Preferably, the clamping plate is L-shaped, and the inner surface of the clamping plate is fitted with a rubber sleeve to prevent excessive clamping force from damaging the workpiece surface and to prevent the workpiece from sliding and shifting due to insecure clamping.

[0009] Preferably, the limiting rod is provided with a scale mark, and the slide is provided with a slot for observing the scale mark. A pointer is fixedly installed at the center of the slot in the slide, thus abandoning the traditional crude positioning method that relies on experience and manual drawing.

[0010] Preferably, the slide has an internal receiving groove, and a cylindrical seat for abutting the upper end of the limiting rod is movably inserted into the slide. A spring is sleeved on one end of the cylindrical seat located in the receiving groove. One end of the spring is fixed to the top of the receiving groove, and the other end of the spring is fixedly connected to the base of the cylindrical seat. A lifting plate is fixedly installed on the upper end of the cylindrical seat.

[0011] Preferably, the slide block has a through groove for communicating with the receiving groove, and the slide block and the limiting rod are slidably connected through the through groove.

[0012] Preferably, the perforated plate has pre-made slots, a fixing block is fixedly installed at the upper end of the perforated plate, and a groove for the fixing block to be inserted at the lower end of the slide is provided. The slide and the fixing block are fixed by cross screws, which realizes the quick replacement of the perforated plate, adapts to the hole enlargement requirements of various hole diameters and shapes, and improves the versatility and working efficiency of the mechanism.

[0013] This positioning mechanism features a bidirectional lead screw threaded into the clamping plate. When the torsion wheel is rotated, the bidirectional lead screw drives the clamping plates on both sides to move synchronously in opposite directions along the limiting rod, thus clamping the steel structure component. The slide block slides along the limiting rod, carrying the drilling plate to the designated hole-enlarging position. The operator can then use a handheld electric drilling device to align with the hole slot and insert it to drill a hole in the steel structure component. This replaces the traditional manual positioning and simple clamping method, solving problems such as large hole position deviation and hole-enlarging failure caused by inaccurate positioning and unstable clamping during steel structure hole enlarging.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This embodiment provides a steel structure hole-expanding and positioning mechanism, such as... Figure 1-3 As shown, the positioning mechanism includes a positioning assembly mounted on the steel structural member 1;

[0021] The positioning assembly includes two relatively distributed fixed plates 3 and a limiting rod 6 fixedly installed between the two fixed plates 3. Clamping plates 2 are symmetrically sleeved on the limiting rod 6. A bidirectional lead screw 4 is threaded into the clamping plate 2. The bidirectional lead screw 4 is rotatably connected between the two fixed plates 3, and one end of the bidirectional lead screw 4 passes through one of the fixed plates 3. A torsion wheel 5 is fixedly installed at the end of the bidirectional lead screw 4 that passes through the fixed plate 3. A slide 7 is provided between the two clamping plates 2 and sleeved on the limiting rod 6. A perforated plate 8 for positioning opening is provided at the lower end of the slide 7. A handle 31 is fixedly installed at the lower end of the fixed plate 3.

[0022] Specifically, the steel structure component 1 is the processing object, the fixed plate 3 serves as the basic support, and a stable frame is built through the limiting rod 6. The fixed plate 3 is connected through the limiting rod 6 and the double-acting screw 4. The torsion wheel 5 drives the double-acting screw 4 to rotate, so that the clamping plate 2 moves along the limiting rod 6 to clamp and fix the steel structure component 1. The slide 7 slides along the limiting rod 6, the drilling plate 8 is used to position the enlarged hole, and the handle 31 is convenient for hand operation.

[0023] The clamping plate 2 is L-shaped, and the inner surface of the clamping plate 2 is fitted with a rubber sleeve.

[0024] More specifically, the clamping plate 2 is designed in an L-shape to increase the contact area with the steel structure component 1 and improve clamping stability. The rubber sleeve on the inner side uses the elasticity and friction of the rubber to prevent the steel structure component 1 from sliding due to vibration or external force during the hole enlargement process. On the other hand, it avoids direct rigid contact between the clamping plate 2 and the steel structure component 1, which could damage the galvanized layer or paint layer on the surface of the steel structure component 1 or cause scratches on the metal surface.

[0025] The limit rod 6 is equipped with a scale mark 9, and the slide 7 has a slot for observing the scale mark 9. A pointer 76 is fixedly installed at the center of the slot in the slide 7.

[0026] Furthermore, a scale mark 9 is arranged on the limit rod 6. When the slide 7 moves, the pointer 76 on it moves synchronously with the slide 7. By pointing the pointer 76 to the scale mark 9, the operator can intuitively and accurately determine the position of the slide 7, and thus determine the enlargement position of the perforation plate 8, realizing visual positioning.

[0027] The slide 7 has an internal receiving groove 71. A cylindrical seat 73 for abutting the upper end of the limiting rod 6 is movably inserted into the slide 7. A spring 74 is sleeved on one end of the cylindrical seat 73 located in the receiving groove 71. One end of the spring 74 is fixed to the top of the receiving groove 71, and the other end of the spring 74 is fixedly connected to the base of the cylindrical seat 73. A lifting plate 75 is fixedly installed on the upper end of the cylindrical seat 73.

[0028] Furthermore, the receiving groove 71 inside the slide 7 accommodates the cylindrical seat 73 and the spring 74. When the spring 74 is in a compressed state, it provides a downward elastic force to the cylindrical seat 73, causing the lower end of the cylindrical seat 73 to abut against the upper end of the limiting rod 6. The frictional force restricts the sliding of the slide 7 along the limiting rod 6, thereby locking the position of the slide 7. Pulling the lifting plate 75 upward causes the cylindrical seat 73 to overcome the elastic force of the spring 74 and move upward, releasing the state of the cylindrical seat 73 abutting against the limiting rod 6. The slide 7 can then slide freely along the limiting rod 6 to adjust its position.

[0029] The slide block 7 has a through groove 72 for communicating with the receiving groove 71. The slide block 7 and the limiting rod 6 are slidably connected through the through groove 72.

[0030] It should be noted that the through groove 72 opened on the slide 7 is connected to the receiving groove 71, providing space for the installation and operation of the cylindrical seat 73. At the same time, the through groove 72 is fitted on the limiting rod 6, serving as the track for the slide 7 to slide along the limiting rod 6, ensuring the straightness and stability of the slide 7 and preventing the slide 7 from getting stuck or shifting during the sliding process.

[0031] The perforated plate 8 has pre-drilled slots 82. A fixing block 81 is fixedly installed on the upper end of the perforated plate 8. A groove for the fixing block 81 to be inserted is provided on the lower end of the slide block 7. The slide block 7 and the fixing block 81 are fixed by cross screws.

[0032] It is worth mentioning that the pre-made slots 82 on the perforated plate 8 are designed with corresponding sizes and shapes according to different hole enlargement requirements, and are used to guide hole enlargement tools such as drill bits to be accurately positioned. The fixing block 81 is inserted into the groove at the lower end of the slide block 7 to achieve the initial positioning of the perforated plate 8. Then, it is fastened with cross screws to complete the connection and fixation of the perforated plate 8 and the slide block 7.

[0033] In use, steel structural component 1 is the processing object, and fixed plate 3 serves as the basic support. A stable frame is built through limiting rod 6. The double-acting screw 4 is threadedly engaged with clamping plate 2. When the torsion wheel 5 is rotated, the double-acting screw 4 drives the clamping plates 2 on both sides to move synchronously in opposite directions along the limiting rod 6, thereby clamping the steel structural component 1. The slide 7 slides along the limiting rod 6, carrying the drilling plate 8 to the designated hole enlargement position. The operator then uses a handheld electric drilling device to align with the pre-made hole slot 82 and insert it to drill a hole in the steel structural component 1.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
