Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling fixtures for steel structure production, specifically a drilling fixture for steel structure production. Background Technology
[0002] Drilling fixtures for steel structure production are positioning and fixing tools used in the steel structure processing process. They are mainly used for drilling holes in steel. Their function is to ensure that the steel can maintain accurate position and stability during the drilling process, thereby improving processing accuracy and production efficiency. These fixtures are usually made of steel, aluminum alloy or other suitable materials, and their design needs to be customized according to the specific steel structure production process and equipment requirements.
[0003] According to the utility model patent application CN204686461U, a steel structure drilling fixture for on-site construction is disclosed, which includes a base plate, two vertical flat-jaw pliers and a guide plate. The two vertical flat-jaw pliers are fixed on the base plate and arranged opposite to each other. The guide plate is provided with guide holes. During operation, the guide plate and the steel plate are stacked together and clamped by the vertical flat-jaw pliers on both sides. The guide plate is located above the steel plate, and the drill bit passes through the guide holes to process the steel plate.
[0004] Although this device has a simple structure, is easy to operate, and is lightweight, using two vertical flat-jaw pliers to clamp the steel plate stably and guiding through guide holes on the guide plate for reliable drilling, making it suitable for on-site construction, it still has limitations. While it firmly clamps the steel plate, adjusting the position of the steel structure requires unscrewing the screws to release the clamping force, which is cumbersome and laborious, thus limiting its practicality. Therefore, we provide a drilling fixture for steel structure production to solve these problems. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a drilling fixture for steel structure production.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling fixture for steel structure production, comprising a base plate, an adjustment mechanism disposed above the base plate, the adjustment mechanism comprising two fixing plates, the bottom surface of each fixing plate being fixedly connected to the upper surface of the base plate, a first screw threadedly connected to the inner wall of each fixing plate, a lifting plate rotatably connected to the bottom end of each first screw, the outer surface of each lifting plate being slidably connected to the inner wall of the fixing plate, and two sets of second limiting rollers rotatably connected to the inner wall of each lifting plate. The inner wall of each plate is rotatably connected to two sets of first limiting rollers. The bottom surface of each fixed plate is fixedly connected to two electric push rods. The telescopic end of each set of electric push rods is fixedly connected to a limiting plate. The inner wall of each limiting plate is in contact with the outer surface of the second limiting roller. A servo motor is fixedly connected to the left side of the base plate. The power output end of each servo motor passes through the base plate and is fixedly installed with a second screw. The right end of the second screw is rotatably connected to the inner wall of the base plate. A push plate is threadedly connected to the outer surface of the second screw. The outer surface of the push plate is slidably connected to the inner wall of the base plate.
[0007] Furthermore, four support legs are fixedly connected to the bottom surface of the base plate, and a base is fixedly connected to the bottom surface of each support leg.
[0008] Furthermore, two fixing blocks are fixedly connected to both the front and back of the base plate, and each fixing block has a positioning hole on its upper surface.
[0009] Furthermore, two reinforcing blocks are fixedly connected to the opposite sides of the two fixed plates, and the opposite sides of the two sets of reinforcing blocks are fixedly connected to the front and back of the base plate, respectively.
[0010] Furthermore, a rotating block is fixedly connected to the top of each of the first screws, and anti-slip grooves are arranged at equal intervals on the outer surface of each rotating block.
[0011] Furthermore, each of the two lifting plates has a stabilizing block fixedly connected to one of its opposite sides, and the outer surface of each stabilizing block is slidably connected to the inner wall of the fixed plate.
[0012] Furthermore, a protective shell is fixedly connected to the outer surface of the servo motor, and the right side of the protective shell is fixedly connected to the left side of the base plate.
[0013] Compared with existing technologies, this drilling fixture for steel structure production has the following advantages:
[0014] This utility model is equipped with a lifting plate, a first screw, a first limiting roller, a second limiting roller, an electric push rod, and a limiting plate. The electric push rod can drive the limiting plate to move, thereby changing the contact state between the second limiting roller and the steel structure, thus releasing the limitation on the second limiting roller and facilitating its rotation. The rotation of the second and first limiting rollers not only facilitates the adjustment and movement of the steel structure plate but also provides a good limiting effect. Furthermore, with the second screw driven by the servo motor to rotate, the push plate moves, easily adjusting the position of the steel structure in the clamp. Unlike traditional equipment, there is no need to turn the screw to release the clamping effect and then adjust, greatly saving operation time and manpower. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0021] This embodiment provides a drilling fixture for steel structure production. This device is used to facilitate the adjustment of the position of the steel structure when clamping it during drilling in steel structure production.
[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A drilling fixture for steel structure production includes a base plate 1. An adjustment mechanism 2 is provided above the base plate 1. The adjustment mechanism 2 includes two fixing plates 201. The bottom surface of each fixing plate 201 is fixedly connected to the upper surface of the base plate 1. Four support legs 211 are fixedly connected to the bottom surface of the base plate 1. A base 212 is fixedly connected to the bottom surface of each support leg 211. This design provides stable support for the entire drilling fixture. The four support legs 211 are evenly distributed under the base plate 1, which enables the fixture to be placed stably on the workbench during steel structure production, avoiding shaking caused by external forces such as vibration generated during drilling operations. The base 212 increases the contact area between the support legs 211 and the workbench, further improving stability and helping to ensure drilling accuracy.
[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each fixed plate 201 has a first screw 202 threadedly connected to its inner wall. Each first screw 202 has a lifting plate 207 rotatably connected to its bottom end. The outer surface of each lifting plate 207 is slidably connected to the inner wall of the fixed plate 201. Two fixed blocks 213 are fixedly connected to the front and back of the base plate 1. Each fixed block 213 has a positioning hole 214 on its upper surface. The fixed blocks 213 and the positioning holes 214 are designed to facilitate the positioning of the fixture on the workbench. The fixed blocks 213 provide a fixed platform, while the positioning holes 214 allow workers to easily fix the device, for example, by using bolts and external positioning pins.
[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each lifting plate 207 has two sets of second limiting rollers 208 rotatably connected to its inner wall, and each fixed plate 201 has two sets of first limiting rollers 206 rotatably connected to its inner wall. Two reinforcing blocks 215 are fixedly connected to the side of each fixed plate 201 that is far apart from each other. The side of each set of reinforcing blocks 215 that is close to each other is fixedly connected to the front and back of the base plate 1, respectively. The presence of the reinforcing blocks 215 enhances the connection strength between the fixed plate 201 and the base plate 1. During the drilling process, a certain force will be generated. The reinforcing blocks 215 can prevent the connection between the fixed plate 201 and the base plate 1 from loosening, ensuring the integrity and stability of the entire adjustment mechanism 2 structure, and thus ensuring the normal operation of the drilling fixture.
[0025] Reference Figure 1 , Figure 2 and Figure 3Two electric push rods 203 are fixedly connected to the bottom surface of each fixed plate 201. A limit plate 204 is fixedly connected to the telescopic end of each set of electric push rods 203. A rotating block 216 is fixedly connected to the top of each first screw 202. Anti-slip grooves 217 are evenly arranged on the outer surface of each rotating block 216. The rotating block 216 provides convenience for operating the first screw 202. The operator can easily rotate the first screw 202 by rotating the rotating block 216. The anti-slip grooves 217 increase the friction between the operator's hand and the rotating block 216, and can effectively prevent slipping even when the hand is oily or wet.
[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner wall of each limiting plate 204 is in contact with the outer surface of the second limiting roller 208. A servo motor 205 is fixedly connected to the left side of the base plate 1. The power output end of each servo motor 205 passes through the base plate 1 and is fixedly installed with a second screw 210. Stabilizing blocks 219 are fixedly connected to the opposite sides of the two lifting plates 207. The outer surface of each stabilizing block 219 is slidably connected to the inner wall of the fixed plate 201. The function of the stabilizing block 219 is to further improve the stability of the lifting plate 207 during the lifting process. When the first screw 202 rotates to make the lifting plate 207 rise and fall along the inner wall of the fixed plate 201, the sliding cooperation between the stabilizing block 219 and the inner wall of the fixed plate 201 can limit the shaking of the lifting plate 207 and ensure the vertical movement of the lifting plate 207.
[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The right end of the second screw 210 is rotatably connected to the inner wall of the base plate 1. The outer surface of the second screw 210 is threaded with a push plate 209. The outer surface of the push plate 209 is slidably connected to the inner wall of the base plate 1. The outer surface of the servo motor 205 is fixedly connected with a protective shell 218. The right side of the protective shell 218 is fixedly connected to the left side of the base plate 1. The protective shell 218 can protect the servo motor 205 from the influence of the external environment. For example, if there is an accidental impact from an external device, the protective shell 218 can also protect the servo motor 205. At the same time, the outer surface of the protective shell 218 is provided with through holes for heat dissipation and connection of circuits.
[0028] Working principle: In use, the operator first connects the power supply to the electric push rod 203 and the servo motor 205 to ensure a stable power supply. The fixed plate 201 in the adjustment mechanism 2 is the basic structure. Then, the lifting plate 207 and the limiting plate 204 are raised by the electric push rod 203 and the first screw 202. Subsequently, the steel plate of the steel structure is placed on the surface of the push plate 209. Then, the lifting plate 207 and the limiting plate 204 are driven by the electric push rod 203 and the first screw 202 to clamp the steel plate. Drilling can then be performed using a drilling tool. The inside of the limiting plate 204 has an anti-slip pad that can contact the second limiting roller 208 to prevent rotation. Furthermore, when it is necessary to adjust the position of the steel plate of the steel structure, the operator activates the electric push rod 203. The upward movement of the electric push rod 203 releases the limit on the second limit roller 208, allowing the second limit roller 208 to rotate. Then, the servo motor 205 can be activated, which drives the second screw 210 to rotate, thereby driving the push plate 209 and the steel plate structure on the push plate 209 to adjust their position. The rotation of the second limit roller 208 and the first limit roller 206 not only facilitates the adjustment and movement of the steel structure plate, but also provides a good limiting effect, allowing the steel plate to be adjusted stably and avoiding affecting the accuracy of subsequent drilling.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
