AI Technical Summary
Existing steel structure drilling jigs are not convenient for adjusting and stably clamping steel structural components of different sizes. When clamping long steel structural components, the clamping mechanism at some locations may affect the clamping effect.
The turntable is driven by a motor to rotate, which in turn moves the sliding pin and guide seat. Multiple clamping mechanisms move synchronously, and the limiting mechanism ensures the stable clamping of the steel structure. The position of the square tube in the guide seat is adjusted by the sliding of the clamping block in the square tube and the elastic return of the spring, so as to avoid the clamping being obstructed by a single clamping block.
It achieves stable clamping of steel structural components of different sizes and lengths, improves the applicability and stability of clamping, and avoids the influence of clamping blocks at a single position.

[0001] This solution belongs to the field of clamping mechanism technology, specifically involving a clamping mechanism for drilling steel structures. Background Technology
[0002] Utility model patent CN213135866U discloses a drilling fixture for steel structures, including a base, a base plate, a first connecting plate, a clamping mechanism, and an installation mechanism. The base plate can be fixedly installed on the top of the base plate, the first connecting plate can be fixedly installed on the left side of the top of the base plate, the clamping mechanism can be assembled on one side of the base plate, and the installation mechanism can be assembled on one side of the first connecting plate and the clamping mechanism. This drilling fixture for steel structures, through the cooperation of the connecting rod, the first connecting seat, the electric push rod, the connecting block, and the second connecting plate, can pull the right-side installation mechanism to move left or right, thereby cooperating with the left-side installation mechanism to clamp and fix the workpiece. This device can stably clamp workpieces of various shapes, facilitates the installation or removal of the fixture head body, is simple and convenient to operate, improves overall work efficiency, is flexible in use, highly practical, and meets the needs of the current market.
[0003] However, the device has certain shortcomings in use. It is not easy to adjust and stably clamp steel structural components of different sizes. Also, when the steel structural components are long, the clamping mechanism at some positions will affect the device's clamping of the steel structural components. Utility Model Content
[0004] The purpose of this solution is to provide a clamping mechanism for drilling steel structures, in order to solve the problem that the device is not easy to adjust for stable clamping of steel structural members of different sizes. At the same time, when the steel structural members are long, the clamping mechanism at some positions will affect the device's clamping of the steel structural members.
[0005] To achieve the above objectives, this solution provides a clamping mechanism for drilling steel structures, including a support plate, a motor fixedly mounted on the lower end of the support plate, a turntable fixedly connected to the lower end of the motor shaft, a limit mechanism on the turntable, a support foot fixedly connected to the lower end of the support plate, a sliding pin slidably connected inside the turntable, a guide seat fixedly connected to the upper end of the sliding pin, and a clamping mechanism on the guide seat.
[0006] The principle of this solution is as follows: During use, the steel structural component is placed on the pallet. For longer steel structural components, some clamping blocks can be pressed into the square tube. The clamping blocks slide within the square tube and automatically reset due to spring elasticity. Simultaneously, the relative position of the square tube within the guide seat can be adjusted by rotating the screw, allowing the device to clamp longer steel structural components. This avoids the obstruction of the device's applicability by clamping blocks in a single position. Then, the motor is started, driving the turntable to rotate. The rotation of the turntable causes the sliding pin to move the guide seat, thereby moving multiple clamping mechanisms to facilitate the clamping and fixing of the steel structural component. At the same time, the downward movement of the sliding ring causes the insert block to enter the corresponding slot within the turntable, limiting the turntable's position and thus increasing the stability of the clamped steel structural component.
[0007] The technical advantages of this solution are as follows: the motor drives the turntable to rotate, which in turn causes the sliding pin to move the guide seat, which in turn causes multiple clamping mechanisms to move, making it easier to clamp and fix the steel structure. At the same time, the moving slip ring causes the insert block to enter the turntable to limit the turntable, thereby making the steel structure more stable after clamping.
[0008] The clamping blocks slide inside the square tube and can automatically reset due to the elasticity of the spring. At the same time, the relative position of the square tube in the guide seat can be adjusted by rotating the screw, so that the device can clamp long steel structural parts and avoid the clamping blocks in a single position from hindering the applicability of the device.
[0009] Furthermore, a protrusion is fixedly connected to the lower end of the guide seat, and the protrusion is slidably connected to the turntable. By setting the protrusion, the friction between the guide seat and the turntable is reduced.
[0010] Furthermore, the limiting mechanism includes a slip ring. A slip ring is slidably connected to the outer side of the support leg, and a connecting ring is slidably connected to the inner side of the support leg. An insert block is fixedly connected to the surface of the connecting ring, and the insert block is slidably connected to the turntable. The turntable is driven to rotate by a motor, which in turn causes the sliding pin to move the guide seat, thereby moving multiple clamping mechanisms to facilitate the clamping and fixing of the steel structural components. Simultaneously, by moving the slip ring, the insert block enters the turntable to limit its movement, thus increasing the stability of the clamped steel structural components.
[0011] Furthermore, the connecting ring and the slip ring are fixedly connected, while the connecting ring and the turntable are slidably connected. The movement of the interlocking blocks is controlled by the connecting ring.
[0012] Furthermore, the clamping mechanism includes a square tube, which is slidably connected inside the guide seat. The square tube and the support plate are slidably connected. A lead screw is mounted inside the guide seat via a bearing. The lead screw and the square tube are connected by a thread. A clamping block is slidably connected inside the square tube, and a spring is installed inside the square tube. The clamping block slides inside the square tube and can automatically reset due to the elasticity of the spring. At the same time, the relative position of the square tube within the guide seat can be adjusted by rotating the lead screw, allowing the device to clamp long steel structural components and avoiding the obstruction of the device's applicability by clamping blocks at a single position.
[0013] Furthermore, one end of the spring is fixedly connected to the square tube, and the other end of the spring is fixedly connected to the clamping block. By incorporating the spring, the clamping block can be easily reset.
[0014] Furthermore, a guide pin is fixedly connected to the surface of the clamping block, and the guide pin is slidably connected to the square tube. The guide pin guides the movement of the clamping block. Attached Figure Description

Detailed Implementation
[0021] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a clamping mechanism for drilling steel structures, including a support plate 1, a motor 2 fixedly mounted on the lower end of the support plate 1, a turntable 3 fixedly connected to the lower end of the motor 2's shaft, a limit mechanism 4 provided on the turntable 3, a support leg 5 fixedly connected to the lower end of the support plate 1, a sliding pin 6 slidably connected inside the turntable 3, a guide seat 7 fixedly connected to the upper end of the sliding pin 6, a protrusion 8 fixedly connected to the lower end of the guide seat 7, the protrusion 8 and the turntable 3 being slidably connected, and by setting the protrusion 8, the friction between the guide seat 7 and the turntable 3 is reduced, and a clamping mechanism 9 is provided on the guide seat 7.
[0022] like Figure 1 , Figure 2 As shown, the limiting mechanism 4 includes a slip ring 41. The slip ring 41 is slidably connected to the outer side of the support leg 5, and a connecting ring 42 is slidably connected to the inner side of the support leg 5. The connecting ring 42 and the slip ring 41 are fixedly connected, and the connecting ring 42 is slidably connected to the turntable 3. By setting the connecting ring 42, the movement of the insert block 43 is controlled. The insert block 43 is fixedly connected to the surface of the connecting ring 42, and the insert block 43 is slidably connected to the turntable 3. The turntable 3 is driven to rotate by the motor 2, which causes the sliding pin 6 to drive the guide seat 7 to move, which in turn causes multiple clamping mechanisms 9 to move, making it easier to clamp and fix the steel structure. At the same time, by moving the slip ring 41, the insert block 43 enters the turntable 3 to limit the turntable 3, thereby making the steel structure more stable after clamping.
[0023] like Figures 1-4 As shown, the clamping mechanism 9 includes a square tube 91. The square tube 91 is slidably connected inside the guide seat 7. The square tube 91 is slidably connected to the support plate 1. A lead screw 92 is installed inside the guide seat 7 via a bearing. The lead screw 92 and the square tube 91 are connected by a thread. A clamping block 93 is slidably connected inside the square tube 91. A spring 94 is installed inside the square tube 91. One end of the spring 94 is fixedly connected to the square tube 91, and the other end of the spring 94 is fixedly connected to the clamping block 93. By setting the spring 94, the clamping block 93 can be easily reset. A guide pin 95 is fixedly connected to the surface of the clamping block 93. The guide pin 95 is slidably connected to the square tube 91. By setting the guide pin 95, the movement of the clamping block 93 is guided. The clamping block 93 slides inside the square tube 91 and can automatically reset due to the elastic action of the spring 94. At the same time, the relative position of the square tube 91 in the guide seat 7 can be adjusted by rotating the lead screw 92, so that the device can clamp long steel structural parts and avoid the clamping block 93 in a single position from hindering the applicability of the device.
[0024] The specific implementation process of this utility model is as follows: In use, the steel structure is placed on the support plate 1. For longer steel structure components, some clamping blocks 93 can be pressed into the square tube 91. The clamping blocks 93 slide within the square tube 91 and can automatically reset due to the elastic action of the spring 94. At the same time, the screw 92 can be rotated to adjust the relative position of the square tube 91 within the guide seat 7, allowing the device to clamp longer steel structure components and preventing a single clamping block 93 from obstructing the applicability of the device. Then, the motor 2 is started, driving the turntable 3 to rotate. The rotation of the turntable 3 causes the sliding pin 6 to move the guide seat 7, thereby moving multiple clamping mechanisms 9 to facilitate the clamping and fixing of the steel structure component. Simultaneously, by moving the sliding ring 41 downward, the insert block 43 enters the corresponding slot within the turntable 3, limiting the turntable 3 and thus increasing the stability of the clamped steel structure component.
[0025] The motor 2 drives the turntable 3 to rotate, which in turn causes the sliding pin 6 to move the guide seat 7, which in turn causes multiple clamping mechanisms 9 to move, making it easier to clamp and fix the steel structure. At the same time, the sliding ring 41 moves the insert block 43 into the turntable 3 to limit the turntable 3, thereby making the steel structure more stable after clamping.
[0026] The clamping block 93 slides inside the square tube 91 and can automatically reset due to the elastic action of the spring 94. At the same time, the screw 92 can be rotated to adjust the relative position of the square tube 91 in the guide seat 7, so that the device can clamp long steel structural parts and avoid the clamping block 93 in a single position from hindering the applicability of the device.
