Description

Technical Field

[0001] This utility model relates to the field of steel structure welding fixtures, and in particular to a steel structure connection clamp-type positioning plate. Background Technology

[0002] In the production and processing of channel steel, it is necessary to weld a connecting plate perpendicular to the inner wall of the channel steel cavity to improve the overall strength of the channel steel.

[0003] To ensure welding accuracy and avoid frequent adjustments to the perpendicularity of the connecting plate during welding, existing technologies typically employ auxiliary tools for positioning the connecting plate. These tools consist primarily of a clamping fixture that holds the main body against the channel steel. A positioning rod extending horizontally along the length of the channel steel is formed in the middle of the main body, and another clamping fixture is installed at the other end of the positioning rod. This clamping fixture holds the connecting plate, ensuring it remains vertically positioned within the channel steel cavity, allowing welding to proceed. However, in actual operation, this auxiliary tool presents the following problems:

[0004] 1. The main body and positioning rod are located on one side of the connecting plate, occupying a large space on one side of the connecting plate, which affects the welding operation on that side of the connecting plate;

[0005] 2. This tool can only position the connecting plate. In actual welding, to ensure the strength of the weld, it is often necessary to apply force to the top surface of the connecting plate so that the bottom surface of the connecting plate is pressed against the inner wall of the channel steel, making the two contact firmly before welding, thereby improving the weld strength. However, this auxiliary tool can only position the connecting plate and cannot apply force to it. In order to ensure the tight contact between the connecting plate and the channel steel, while the clamping fixture at the end of the positioning rod clamps the connecting plate, another person needs to apply force to the top surface of the connecting plate and press it against the connecting plate. This makes the operation cumbersome and requires a lot of manpower. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a steel structure connection clamp-type positioning plate, which solves the problems of the traditional technology affecting the welding work on the side of the connecting plate after positioning the connecting plate, as well as the inability to apply force to tighten the connecting plate, requiring manual force to be applied to the connecting plate when positioning it, resulting in cumbersome operation and high operator input.

[0007] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0008] A steel structure connecting clamp-type positioning plate includes a shell, which is elongated and strip-shaped. An X-axis opening and closing clamp is installed on the inner wall of the shell, and the opening and closing clamping direction of the X-axis opening and closing clamp is the same as the length direction of the shell.

[0009] A Y-axis opening and closing clamp is slidably installed in the middle of the housing. The opening and closing clamping direction of the Y-axis opening and closing clamp is the same as the width direction of the housing. The Y-axis opening and closing clamp is driven by a moving component to slide against the housing in the height direction.

[0010] Preferably, the X-direction opening and closing clamp includes sliding connecting plates symmetrically slidably connected to the inner wall of the housing. An X-direction clamping plate is fixed at the lower end of the two sliding connecting plates on the side close to each other. The X-direction clamping plate is arranged in an inverted L-shape, and the short side of the two X-direction clamping plates is located on the side close to each other.

[0011] The middle part of the housing is rotatably connected to an X-direction bidirectional screw via a bearing. The length direction of the X-direction bidirectional screw coincides with the length direction of the housing. The two sliding connecting plates are respectively threaded to both ends of the X-direction bidirectional screw through the first threaded hole. One end of the X-direction bidirectional screw extends through the housing to the outside of the housing and is fixed with a handwheel.

[0012] Preferably, the Y-direction opening and closing clamp includes a sliding frame slidably connected to the middle of the housing, the opening of the sliding frame facing downward, the length direction of the sliding frame being the same as the width direction of the housing, and a Y-direction clamping plate symmetrically slidably connected to the inner wall of the opening of the sliding frame, the lower end of the Y-direction clamping plate extending to the bottom of the housing;

[0013] The inner wall of the sliding frame is rotatably connected to a Y-direction bidirectional screw via a bearing. The length direction of the Y-direction bidirectional screw is the same as the width direction of the housing. One end of the Y-direction bidirectional screw extends to the outside of the sliding frame and is fixed with a first knob. Two Y-direction clamps are respectively threaded to both ends of the Y-direction bidirectional screw through second threaded holes.

[0014] Preferably, the Y-direction bidirectional screw and the X-direction bidirectional screw are staggered.

[0015] Preferably, the Y-direction bidirectional screw is located above the X-direction bidirectional screw, which is located at the center of the opening of the sliding frame and between the two Y-direction clamps.

[0016] Preferably, the movable component includes a Z-axis screw threaded to the top surface of the housing via a third threaded hole. The axis of the Z-axis screw is perpendicular to the top surface of the housing. The lower end of the Z-axis screw extends to the inner side of the housing and is rotatably connected to the top surface of the sliding frame. A second knob is fixed to the top of the Z-axis screw.

[0017] Compared with the prior art, the advantages of this utility model are as follows:

[0018] This invention directly arranges the clamping structure for holding the connecting plate within the inner cavity of the housing, eliminating the need for a long positioning rod on one side of the housing. Furthermore, after positioning the connecting plate, there are no obstructions on either side of the connecting plate, preventing interference with the welding process. The overall structure is also more compact and smaller than existing technologies, making it easier to store and carry. By sliding the clamping structure for holding the connecting plate to the housing and using a Z-axis screw to drive the clamping structure to rise and fall, the Z-axis screw can be rotated after the connecting plate is positioned, applying force to the connecting plate and pressing it against the inner wall of the channel steel. Compared to traditional technologies, this eliminates the need for two people to perform positioning and pressing operations separately; one person can complete both operations in sequence, making the operation more convenient and practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 5 This embodiment provides a steel structure connection clamp-type positioning plate, including a housing 1, which is arranged in a long strip shape;

[0027] The inner wall of the housing 1 is symmetrically connected with sliding connecting plates 2. The lower ends of the two sliding connecting plates 2 that are close to each other are fixed with X-direction clamping plates 3. The X-direction clamping plates 3 are arranged in an inverted L shape. The short side 301 of the two X-direction clamping plates 3 is located on the side where the two X-direction clamping plates 3 are close to each other.

[0028] During the positioning of the connecting plate, the housing 1 needs to be placed on the channel steel perpendicularly, while the two X-direction clamping plates 3 are located on both sides of the channel steel. Finally, the two X-direction clamping plates 3 are driven to clamp onto the outer walls of both sides of the channel steel, and the short side 301 of the two X-direction clamping plates 3 are placed on the top surface of the channel steel. In this way, the housing 1 can be positioned on the channel steel and the perpendicularity between the two can be guaranteed.

[0029] The middle part of the housing 1 is rotatably connected to the X-direction bidirectional screw 4 via a bearing. The length direction of the X-direction bidirectional screw 4 coincides with the length direction of the housing 1. The two sliding connecting plates 2 are respectively threaded to the two ends of the X-direction bidirectional screw 4 through the first threaded hole. One end of the X-direction bidirectional screw 4 passes through the housing 1 and extends to the outside of the housing 1 and is fixed with a handwheel 5.

[0030] When driving the two X-direction clamping plates 3 to clamp or open, by turning the handwheel 5, the X-direction bidirectional screw 4 is driven to rotate, thereby enabling the two sliding connecting plates 2 to slide together or away from each other on the inner wall of the housing 1, thus causing the X-direction clamping plates 3 to open or close.

[0031] Two sliding grooves are symmetrically opened in the middle of the housing 1. Sliding frames 6 are slidably connected to the inner walls of the two sliding grooves. The vertical inner walls of the sliding grooves are inserted into the grooves formed on the outer walls of the sliding frames 6, thereby limiting the horizontal direction of the sliding frames 6 and preventing the sliding frames 6 and the housing 1 from sliding and moving in the horizontal direction. The opening of the sliding frames 6 faces downward. The length direction of the sliding frames 6 is the same as the width direction of the housing 1. Y-axis clamping plates 7 are symmetrically slidably connected to the inner walls of the opening of the sliding frames 6. The lower end of the Y-axis clamping plates 7 extends to the bottom of the housing 1.

[0032] The inner wall of the sliding frame 6 is rotatably connected to a Y-direction bidirectional screw 8 via a bearing. The length direction of the Y-direction bidirectional screw 8 is the same as the width direction of the housing 1. One end of the Y-direction bidirectional screw 8 extends to the outside of the sliding frame 6 and is fixed with a first knob 9. Two Y-direction clamping plates 7 are respectively threaded to the two ends of the Y-direction bidirectional screw 8 through second threaded holes. The Y-direction bidirectional screw 8 is located above the X-direction bidirectional screw 4, and there is a certain gap between them. The X-direction bidirectional screw 4 is located in the middle of the opening of the sliding frame 6 and is located between the two Y-direction clamping plates 7.

[0033] When using the Y-axis clamping plate 7 to clamp the connecting plate, by rotating the first knob 9, the Y-axis bidirectional screw 8 is driven to rotate, so that the two Y-axis clamping plates 7 slide in a direction closer to each other on the inner wall of the sliding frame 6 to clamp the connecting plate.

[0034] The top surface of housing 1 is threaded with a Z-axis screw 10 through a third threaded hole. The axis of the Z-axis screw 10 is perpendicular to the top surface of housing 1. The lower end of the Z-axis screw 10 extends to the inside of housing 1 and is rotatably connected to the top surface of sliding frame 6. A second knob 11 is fixed to the top of the Z-axis screw 10.

[0035] The entire operation process of the fixture is as follows:

[0036] 1. First, place the connecting plate inside the channel steel, and keep the connecting plate vertical;

[0037] 2. Then place the clamps so that the housing 1 is lowered from the top of the connecting plate to the top surface of the channel steel, ensuring that the two Y-direction clamps 7 are respectively inserted on both sides of the connecting plate until the short side 301 of the two X-direction clamps 3 is close to the top surface of the channel steel. Then turn the handwheel 5 to use the X-direction clamps 3 to clamp the channel steel and ensure that the short side 301 is placed on the top surface of the channel steel, thus completing the positioning of the housing 1.

[0038] 3. Then rotate the first knob 9 to make the two Y-axis clamping plates 7 move closer together to clamp the connecting plate and position the connecting plate.

[0039] 4. Rotate the second knob 11 to bring the Z-axis screw 10 closer to the channel steel, push the sliding frame 6, and make the connecting plate press against the inner wall of the channel steel;

[0040] 5. Perform welding work on the connecting plate and the channel steel.

[0041] In summary, by directly placing the clamping structure of the connecting plate in the inner cavity of the housing 1, this utility model eliminates the need for a long positioning rod on one side of the housing 1. As a result, after the connecting plate is positioned, there is no obstruction on either side, and the welding operation is not disturbed. Moreover, the overall structure is more compact and smaller in size than the prior art, making it more convenient to store and carry.

[0042] In addition, the clamping structure of the clamping connecting plate is slidably connected to the housing 1, and the Z-axis screw 10 is used to drive it to rise and fall. After the connecting plate is positioned, rotating the Z-axis screw 10 can apply force to it, so that it is tightly pressed against the inner wall of the channel steel. Compared with traditional technology, it is no longer necessary for two people to do the positioning and pressing work separately. One person can easily complete the work in sequence, which is convenient and practical.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
