Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a drilling clamp for steel structures. Background Technology

[0002] A drilling jig for steel structures is a clamping tool used to drill holes in steel structures, ensuring that the steel structure is fixed and that drilling is easy.

[0003] According to patent number CN202220213531.9, the specific invention is a fixture for drilling steel structure workpieces, including a worktable. A fixed plate is fixedly connected to one end of the top of the worktable, and an electric push rod is fixedly installed at the other end. A movable plate is fixedly connected to the end of the electric push rod. Clamping plates are fixedly connected to one side of both the fixed plate and the movable plate. A drilling notch is provided in the middle of the worktable. A chip collection drawer is slidably connected to the bottom of the worktable. A transverse threaded rod is internally threaded to the worktable. A first side plate is rotatably connected to one end of the transverse threaded rod. A first slider is fixedly connected to the bottom of the first side plate. A longitudinal threaded rod is internally threaded to the first slider. The chip drawer is used to collect the chips generated during drilling, preventing chips from scattering on the ground. The clamping plates, which are fixed by bolts, can be disassembled and replaced, making it easy to change different clamping plates according to the different specifications and shapes of the workpiece to be drilled, thus ensuring drilling accuracy. The position of the worktable can be finely adjusted, improving drilling accuracy.

[0004] The search also yielded patent number CN202421011811.7, which specifically describes a drilling fixture for steel structural components. The fixture includes a fixture platform with clamping plates and a first handle. Connecting walls are fixedly connected to both sides of the top of the fixture platform, and each connecting wall has a support block. A connecting longitudinal rod is fixedly connected to the bottom of each support block, and a connecting transverse rod is fixedly connected to each longitudinal rod. Lifting plates are fixedly connected to both ends of the connecting transverse rod. A T-shaped steel piece is placed on the fixture platform, with the top transverse plate of the T-shaped steel placed on the support blocks on both sides. The two clamping plates hold the longitudinal plate of the T-shaped steel in place. A drilling tool is then used to drill holes in the transverse plate of the T-shaped steel. Because the transverse plate has support blocks at both ends, it is not deformed by downward pressure during drilling.

[0005] While the two patents mentioned above achieve different clamping and support effects for steel plates, they can only perform planar drilling. For special drilling requirements, such as inclined holes at different angles, the existing clamping methods cannot achieve the effect of inclined clamping. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drilling fixture for steel structures, which solves the problem that existing clamping methods cannot achieve tilting clamping effects.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling fixture for steel structures, comprising a base plate, an arc-shaped mounting seat disposed at the center of the top of the base plate, a first arc-shaped rotating shaft plate rotatably sleeved within the inner cavity of the arc-shaped mounting seat, a second arc-shaped rotating shaft plate slidably sleeved within the inner cavity of the first arc-shaped rotating shaft plate, and protective plates symmetrically fixed to the surfaces of the arc-shaped mounting seat and the first arc-shaped rotating shaft plate by screws, a lever symmetrically fixed to the staggered sides of the first and second arc-shaped rotating shaft plates, and a cross groove provided on each side, a limit block slidably sleeved within the inner cavity of the cross groove, and a rotating handle threadedly sleeved within the inner cavity of the limit block, an angle scale provided on the side edges of the first and second arc-shaped rotating shaft plates, and a clamping seat provided on the top of the second arc-shaped rotating shaft plate.

[0008] Preferably, the first arc-shaped rotating shaft plate and the second arc-shaped rotating shaft plate slide alternately.

[0009] Preferably, the surface of the guard plate is flush with the surface of the arc-shaped mounting base and the first arc-shaped rotating shaft plate.

[0010] Preferably, the cross groove is arc-shaped and has the same curvature as the first arc-shaped rotating shaft plate and the second arc-shaped rotating shaft plate.

[0011] Preferably, the rotating handle is threaded onto the surface of the guard plate.

[0012] Preferably, the surface of the clamping seat is symmetrically threaded with a lead screw, and the inner cavity of the lead screw is provided with a cavity.

[0013] This utility model provides a drilling fixture for steel structures. Compared with the prior art, it has the following advantages:

[0014] 1. This drilling fixture for steel structures uses rotating handles on the sides of the second and first arc-shaped rotating shaft plates to loosen the fastening of the second and first arc-shaped rotating shaft plates. Then, by using a lever to rotate the second and first arc-shaped rotating shaft plates respectively, different angles of tilting can be achieved, thereby completing the drilling of inclined holes.

[0015] 2. The drilling fixture for the steel structure has V-shaped grooves symmetrically arranged on the surface of the guard plate, and the angle scales on the surfaces of the first and second arc-shaped rotating shaft plates can be observed through the grooves, so as to accurately determine the tilt angle.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a drilling fixture for steel structures, including a base plate 1, an arc-shaped mounting seat 2 is provided in the middle of the top of the base plate 1, and a first arc-shaped rotating shaft plate 3 is rotatably sleeved in the inner cavity of the arc-shaped mounting seat 2, and a second arc-shaped rotating shaft plate 4 is slidably sleeved in the inner cavity of the first arc-shaped rotating shaft plate 3. The first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4 slide alternately, thereby realizing left-right and front-back rotation and forming various angles of tilt.

[0023] The surfaces of the arc-shaped mounting base 2 and the first arc-shaped rotating shaft plate 3 are respectively symmetrically fixed with guard plates 8 by screws. Angle scales 7 are provided on the side edges of the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4. The guard plates 8 are flush with the surfaces of the arc-shaped mounting base 2 and the first arc-shaped rotating shaft plate 3. The guard plates 8 can limit the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4 to prevent them from falling off. The surface of the guard plates 8 is symmetrically provided with V-shaped clamping grooves, and the angle scales 7 on the surfaces of the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4 can be observed through the clamping grooves.

[0024] A lever 6 is symmetrically fixedly connected to the intersecting sides of the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4. The lever 6 is used to oscillate the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4 to rotate left, right and forward. A cross groove 10 is opened on each side. The cross groove 10 is arc-shaped and has the same curvature as the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4. A limit block 11 is slidably sleeved in the inner cavity of the cross groove 10. The two ends of the limit block 11 are arc-shaped and match the inner cavity of the cross groove 10 and slide in the cross groove 10. A rotating handle 9 is threadedly sleeved in the inner cavity of the limit block 11. The rotating handle 9 is threadedly sleeved on the surface of the guard plate 8. The limit block 11 is used to limit the rotation of the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4 and provides support with the connected rotating handle 9. The rotating handle 9 also realizes the loosening and tightening of the first arc-shaped rotating shaft plate 3 and the second arc-shaped rotating shaft plate 4.

[0025] The top of the second arc-shaped rotating shaft plate 4 is provided with a clamping seat 5. The surface of the clamping seat 5 is symmetrically threaded with a lead screw 51, and the inner cavity of the lead screw 51 is provided with a cavity 52. ​​The lead screw 51 is used to fasten the steel structure, while the cavity 52 is used to prevent the drill bit from directly contacting the inner wall of the clamping seat 5 during drilling.

[0026] During operation or use, first place the steel structure in the inner cavity of the clamping seat 5 and rotate the lead screw 51 to tighten the steel structure. Then, install the base plate 1 on the drilling equipment using mounting screws. When drilling at different angles is required, first rotate the side handle 9 of the first arc-shaped rotating shaft plate 3 to rotate the handle 9 on the guard plate 8, ensuring that one end of the handle 9 is no longer against the inner wall of the cross groove 10 and is located in the inner cavity of the limit block 11. Then, move the actuating rod 6 on the first arc-shaped rotating shaft plate 3. The lever 6 drives the first arc-shaped rotating shaft plate 3 to rotate left and right on the arc-shaped mounting base 2. At the same time, the limiting block 11 will limit the movement in the cross slide groove 10, which also achieves the support effect. The angle value can be observed through the angle scale 7. After the angle is determined, the rotating handle 9 is rotated so that one end of the rotating handle 9 passes through the limiting block 11 and abuts against the inner wall of the cross slide groove 10 to tighten the first arc-shaped rotating shaft plate 3. At this time, the steel structure held by the clamping seat 5 also tilts. Then, drilling can be performed using drilling equipment.

[0027] Additionally, when the rotating handle 9 on the side of the second arc-shaped rotating shaft plate 4 is rotated, the rotating handle 9 is loosened from the fastening of the second arc-shaped rotating shaft plate 4. Following the same steps as above, the toggle lever 6 is moved to drive the second arc-shaped rotating shaft plate 4 to rotate back and forth on the first arc-shaped rotating shaft plate 3. The angle value is observed through the angle scale 7. After the angle is determined, the rotating handle 9 is rotated so that one end of the rotating handle 9 passes through the limit block 11 and abuts against the inner wall of the cross slide groove 10 to fasten the second arc-shaped rotating shaft plate 4. This allows drilling at various different angles to be achieved.
