Description

Technical Field

[0001] This application relates to the field of drilling auxiliary equipment technology, and in particular to a steel plate drilling fixture. Background Technology

[0002] Steel plates are an essential material in daily construction. In building construction, the fabrication and processing of many steel structures are completed on the construction site. However, there are usually no large machine tools, drilling machines, or other equipment on the construction site, so drilling machines are usually used to drill holes in the steel plates.

[0003] When drilling, clamps are needed to fix the steel plate. On the construction site, temporary equipment is often used to fix the steel plate.

[0004] The existing technical solutions mentioned above have the following drawbacks: the temporary fixture is not stable, which can easily cause deviations in the processing position and reduce work efficiency. Utility Model Content

[0005] This application provides a steel plate drilling fixture to facilitate the fixing of steel plates, improve the stability of the drilling fixture, and increase work efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A steel plate drilling fixture includes a clamping platform and an operating platform. The clamping platform is mounted on the operating platform, and a clamping plate is hinged to the clamping platform. An electric push rod is mounted on the bottom of the clamping platform, and a connecting plate is fixed to the head of the electric push rod. A transmission assembly is provided between the connecting plate and the clamping plate, and the transmission assembly can drive the clamping plate to rotate.

[0008] By adopting the above technical solution, controlling the extension and retraction of the electric push rod can enable the transmission component to drive the clamping plate to rotate, making it convenient for workers to put in and take out the steel plate. The electric push rod drives the clamping plate to press the top and bottom surfaces of the steel plate, which facilitates the fixing of the steel plate, improves the stability of the drilling fixture, increases work efficiency, and can reduce the deformation of the steel plate after drilling, thereby ensuring the performance of the steel plate.

[0009] Optionally, the clamping plate is provided with a floating component, which is fixed to the pressure plate. The floating component includes a sliding plate, which is embedded inside the clamping plate and can slide within the clamping plate. A guide rod is passed through and slidably connected to the sliding plate. A first elastic element is sleeved on the peripheral wall of the guide rod, and the first elastic element is located between the sliding plate and the clamping plate.

[0010] By adopting the above technical solution, when pressing the steel plate, the sliding plate slides in the clamping plate through the guide rod and the first elastic element, which enables the pressure plate to clamp steel plates of different thicknesses.

[0011] Optionally, the transmission assembly includes a first link, a second link, and a third link. One end of the first link is hinged to the clamping plate, the other end of the first link is hinged to one end of the second link, the other end of the second link is hinged to one end of the third link, and the other end of the third link is hinged to the connecting plate.

[0012] By adopting the above technical solution, when the electric push rod retracts, the first link pushes the second and third links, which can cause the clamping plate connected to the third link to flip away from the clamping table. When the electric push rod extends, the first link pulls the second and third links, which can cause the clamping plate connected to the third link to rotate to fit the clamping table and clamp the steel plate, making it convenient for workers to put in and take out the steel plate.

[0013] Optionally, a connecting frame is provided between the pressure plate and the sliding plate, the connecting frame is hinged to the sliding plate, and the connecting frame is fixedly connected to the pressure plate.

[0014] By adopting the above technical solution, the connecting frame can adaptively adjust the angle, so that the pressure plate can adapt to the change of a certain angle on the steel plate surface, and can stably clamp steel plates of different thicknesses.

[0015] Optionally, rubber pads are fixed to the bottom of both the clamping plate and the pressure plate.

[0016] By adopting the above technical solutions, the stability of the clamping plate and pressure plate in fixing the steel plate can be improved, the friction of the clamp on the clamping surface of the steel plate can be increased, and the deformation of the steel plate caused by sliding during drilling can be reduced.

[0017] Optionally, a support plate is installed on the clamping platform.

[0018] By adopting the above technical solution, the height of the support plate can be adjusted according to the thickness of the steel plate to be processed, so that the clamping plate and the pressure plate can fully fix the steel plate, and the support plate can support the steel plate from the bottom, reducing the deformation of the steel plate during drilling.

[0019] Optionally, a connecting shaft is fixedly connected to the hinge joint between the clamping plate and the clamping table. A reset assembly is provided on the peripheral wall of the connecting shaft. The reset assembly includes an extension plate, which is fixedly connected to the peripheral wall of the connecting shaft. A limit block is fixedly connected to the clamping table. A guide ring is inserted and fixedly connected inside the limit block. The guide ring is inserted and slidably connected to the extension plate. A second elastic element is sleeved on the guide ring. The second elastic element is located between the extension plate and the limit block.

[0020] By adopting the above technical solution, the clamping plate can be reset through the second elastic element between the extension plate and the limiting block, which facilitates the opening of the clamping plate and the insertion and removal of the steel plate.

[0021] Optionally, the top surface of the clamping table is provided with a waste outlet, and a receiving box is slidably arranged inside the clamping table. The receiving box is connected to the waste outlet and can be pulled out from inside the clamping table.

[0022] By adopting the above technical solution, the drilling debris generated can enter the collection box through the waste inlet, facilitating the collection of drilling debris and making the workbench easier to clean.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a clamping platform, clamping plate, electric push rod and transmission assembly, the transmission assembly can drive the clamping plate to rotate when the electric push rod extends and retracts, making it convenient for workers to put in and take out steel plates. The electric push rod drives the clamping plate to press the top and bottom surfaces of the steel plate, which is convenient for fixing the steel plate, improving the stability of the drilling fixture, improving work efficiency, and reducing the deformation of the steel plate after drilling, thereby ensuring the performance of the steel plate;

[0025] 2. By setting up floating components and connecting frames, the pressure plate can adapt to changes in a certain angle on the surface of the steel plate, and the sliding plate slides in the clamping plate through the guide rod and the first elastic element, which can stably clamp steel plates of different thicknesses;

[0026] 3. By setting rubber pads and support plates, the stability of the clamping plate and pressure plate in fixing the steel plate can be improved, the friction of the clamp on the clamping surface of the steel plate can be increased, and the deformation of the steel plate caused by sliding during drilling can be reduced.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a steel plate drilling fixture, as shown in the embodiments below. Figure 1 The fixture includes a clamping platform 1 and an operating platform. The clamping platform 1 is mounted on the operating platform, and two horizontally symmetrical clamping plates 2 are connected to the clamping platform 1. A connecting shaft 21 is passed through and fixed to one side of the two clamping plates 2 facing away from each other. The two ends of the connecting shaft 21 extend out of the clamping plates 2 and are hinged to the top of the clamping platform 1.

[0035] Reference Figure 2 The fixture also includes a lifting plate 5, and an electric push rod 6 is connected to the bottom of the clamping platform 1. One end of the electric push rod 6 is fixed to the center of the bottom surface of the clamping platform 1 by bolts, and the other end of the electric push rod 6 is fixed to the center of the surface of the connecting plate 5 by bolts. The extension and retraction of the electric push rod 6 can adjust the height of the connecting plate 5.

[0036] Reference Figure 2 and Figure 3 A floating component 7 is embedded in the bottom of the clamping plate 2, and a pressure plate 3 is welded to the side of the floating component 7 near the clamping table 1.

[0037] Reference Figure 3 The floating component 7 includes a sliding plate 71. A movable groove for mounting the sliding plate 71 is provided on the side of the clamping plate 2 near the clamping table 1. The sidewall of the sliding plate 71 slides against the inner sidewall of the movable groove. Several guide rods 72 are threaded through and slidably connected around the sliding plate 71. The length direction of the guide rods 72 is perpendicular to the surface of the sliding plate 71. A first elastic element 73 is sleeved on the guide rods 72. The first elastic element 73 is located between the clamping plate 2 and the sliding plate 71. In this embodiment, the first elastic element 73 is a spring.

[0038] Reference Figure 3 A connecting frame 8 is provided between the pressure plate 3 and the sliding plate 71. The connecting frame 8 is a strip of metal plate bent into a V shape. The bent part of the connecting frame 8 is hinged to the plate surface of the sliding plate 71 facing the pressure plate 3. The two ends of the connecting frame 8 away from the bent part are welded to the plate surface of the pressure plate 3 facing the connecting frame 8.

[0039] Reference Figure 4 The two clamping plates 2 are connected by a transmission component 4 at a close section. The transmission component 4 can pull the clamping plates 2 to rotate toward the clamping table 1.

[0040] When clamping the steel plate, the steel plate is placed on the clamping table 1. The placement position of the steel plate is determined according to the drilling location. The electric push rod 6 extends, and the transmission component 4 drives the two clamping plates 2 to rotate. After the clamping plates 2 rotate to a horizontal position, they can press and fix the steel plate on the clamping table 1. Then, drilling is performed on the fixed steel plate. After drilling is completed, the electric push rod 6 shortens, driving the two clamping plates 2 to rotate. When the two clamping plates 2 are fully open, the drilled steel plate is removed, and the un-drilled steel plate is placed back on the clamping table 1. By controlling the extension of the electric push rod 6, the clamping plates 2 can be rotated towards the clamping table 1, allowing the clamping plates 2 to press and fix the steel plate. The electric push rod 6 drives the clamping plates 2 to press the top and bottom surfaces of the steel plate, facilitating the fixation of the steel plate, improving the stability of the drilling fixture, increasing work efficiency, and reducing the deformation of the steel plate after drilling, thereby ensuring the performance of the steel plate.

[0041] When pressing the steel plate, the sliding plate 71 can slide inside the clamping plate 2 via the guide rod 72 and the first elastic element 73, enabling the pressure plate 3 to clamp steel plates of different thicknesses. The connecting frame 8 is hinged to the sliding plate 71, and the connecting frame 8 can adaptively adjust its angle, allowing the pressure plate 3 to adapt to changes in the angle of the steel plate surface, thus enabling stable clamping of steel plates of different thicknesses.

[0042] Reference Figure 4 The transmission assembly 4 includes a first connecting rod 41, a second connecting rod 42, and a third connecting rod 43. A fixed shaft 22 is inserted through and fixed to a section of the clamping plate 2 away from the connecting shaft 21. Both ends of the fixed shaft 22 extend out of the clamping plate 2 and are fixed to one end of the first connecting rod 41 by bolts. The other end of the first connecting rod 41 is hinged to one end of the second connecting rod 42. The other end of the second connecting rod 42 is hinged to one end of the third connecting rod 43. The other end of the third connecting rod 43 is fixed to the side walls at both ends of the connecting plate 5 in the length direction by bolts. The first connecting rod 41, the second connecting rod 42, and the third connecting rod 43 are each provided in four sets. The four sets of connecting rods are respectively connected to each connecting shaft 21. The two ends of the second connecting rod 42 are provided with limiting parts. The limiting parts are located on the opposite side of two adjacent second connecting rods 42. The limiting parts can limit the rotation angle at the hinge at both ends of the second connecting rod 42. When the worker takes out the processed steel plate, the electric push rod 6 retracts, which can drive the transmission component 4 to flip the two clamping plates 2 away from the clamping table 1, so that the worker can open the clamping plates 2 and take out the steel plate.

[0043] Reference Figure 3Rubber pads 10 are installed at the bottom of the clamping plate 2 and the pressure plate 3 respectively. The rubber pads 10 can improve the stability of the clamping plate 2 and the pressure plate 3 in fixing the steel plate, increase the friction of the clamp on the clamping surface of the steel plate, and reduce the deformation of the steel plate caused by sliding during drilling.

[0044] Reference Figure 3 and Figure 4 A waste outlet 11 is provided at the center of the top surface of the clamping table 1. A receiving box 12 is slidably installed inside the clamping table 1. The top of the receiving box 12 has an opening, allowing it to be pulled out from inside the clamping table 1. The waste outlet 11 is located above and communicates with the receiving box 12. Drilling debris can enter the receiving box 12 through the waste outlet 11, facilitating the collection of drilling debris and making the cleaning of the workbench easier.

[0045] Reference Figure 4 A support plate 13 is installed at the center of the top surface of the clamping table 1, and the height of the support plate 13 is adjustable. The height of the support plate 13 is adjusted according to the thickness of the steel plate to be processed, so that the clamping plate 2 and the pressure plate 3 can fully fix the steel plate, and at the same time, the support plate 13 can support the steel plate from the bottom, reducing the deformation of the steel plate during drilling.

[0046] Reference Figure 4 and Figure 5 A reset assembly 9 is provided at the hinge point between the clamping plate 2 and the clamping table 1. The reset assembly 9 includes an extension plate 91. The extension plate 91 is welded to the peripheral wall of the connecting shaft 21. When the surface of the clamping plate 2 is placed horizontally, the surface of the extension plate 91 is also in a horizontal state. A limit block 92 is welded to the clamping table 1 near the connecting shaft 21. The limit block 92 is trapezoidal and its inclined side is inclined towards the clamping plate 2. A guide ring 93 with the same center as the connecting shaft 21 is inserted and welded into the limit block 92. The guide ring 93 is inserted and slidably connected to the surface of the extension plate 91. A second elastic element 94 is sleeved on the guide ring 93. The second elastic element 94 is located between the inclined surface of the extension plate 91 and the limit block 92. In this embodiment, the second elastic element 94 is a spring.

[0047] When clamping the steel plate, the clamping plate 2 can be reset through the second elastic element 94 between the extension plate 91 and the limiting block 92, which makes it easy to open the clamping plate 2 and facilitates the insertion and removal of the steel plate.
