Description

Technical Field

[0001] The invention belongs to the technical field of clamps, and in particular relates to a clamping tool for gas box welding. Background Art

[0002] In the gas box manufacturing industry, the gas box welding process is a crucial link, and its welding quality directly affects the overall performance and service life of the gas box. The gas box is usually composed of multiple plates, which need to be accurately positioned and clamped before welding to ensure stability and welding quality during the welding process.

[0003] However, traditional clamps often cannot meet the positioning requirements of multiple plates at the same time. During the welding process, once a plate is offset, it will affect the welding effect of the entire air box, and even cause welding failure, thereby increasing production costs. At the same time, when the air box semi-finished product needs to be adjusted in position during the welding process, it is often necessary to release the original clamp first and then re-clamp and fix it in the new position. This process is not only time-consuming and labor-intensive, but also increases the labor intensity of the operator and leads to a significant decrease in production efficiency.

[0010] There are two groups of control components and they correspond one to one with the two groups of vertical pressing components. The control components include push rods. The push rods are the same in number as the support frames and are slidably connected left and right. One end of the push rod is fixedly connected to a block matching the vertical roller.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-7 As shown, a clamping tool for gas box welding includes a base 1, a hydraulic rod 2 is vertically installed on the upper side of the base 1, a support platform 3 is installed on the top of the output end of the hydraulic rod 2, a plurality of universal balls 4 are evenly installed on the upper side of the support platform 3, a vertical pressing assembly is installed on the upper side of the universal balls 4, and a vertical fixing device is installed on the side of the base 1;

[0026] There are two groups of vertical fixing devices, which are respectively located on the front side of the base 1 and the right side of the base 1. The internal structures of the two groups of vertical fixing devices are exactly the same. The vertical fixing devices include a fixing frame 5, one of which is fixedly connected to the right side of the base 1, and a plurality of rotating wheels 6 rotatably connected to the fixing frame 5 are evenly installed on the front and back of the lower side of the fixing frame 5. A plurality of supporting frames 7 evenly distributed front and back are installed on the left side of the fixing frame 5. Fixed columns 8 are fixed at both upper and lower ends of the right side of the supporting frame 7. A movable bracket 9 is installed on the right side of the fixed column 8 for sliding left and right. A vertical roller 29 is rotatably installed on the right side of the movable bracket 9. The fixed column 8 is sleeved with a tensioning spring 10 fixedly connected to the support frame 7 and the movable bracket 9 respectively, a pressing side plate 11 is hingedly connected to the upper and lower sides of the right side of the fixed frame 5, a left-right oriented slide rail 12 is installed on the right side of the fixed frame 5, a slider 13 is slidably connected to the upper side of the slide rail 12, a connecting rod 30 is hinged on the upper side of the slider 13, the upper end of the connecting rod 30 is hinged to the pressing side plate 11, a screw rod 14 is rotatably installed on the upper side of the slide rail 12, the screw rod 14 is threadedly connected to the slider 13, and a transmission component for controlling the rotation of the screw rod 14 and a control component for limiting the rotation of the vertical roller 29 are installed in the middle of the base 1.

[0027] When the present invention is in use, the slider 13 is in the innermost stroke of the slide rail 12. At this time, the pressing side plate 11 is perpendicular to the ground. Then, the two plates on the side of the air box that need to be welded are placed on the upper side of the rotating wheel 6 of the different vertical fixing devices on the front side on the right side. The vertical roller 29 presses the corresponding plates to the side of the pressing side plate 11. At this time, the position of the plates can be adjusted along the rotation direction of the rotating wheel 6. After the position of the plates is adjusted to the appropriate position, the control component can be controlled to stop the vertical roller 29 from rotating. At this time, the plates are fixed, and then other plates are placed on the upper side of the support platform 3. The hydraulic rod 2 can adjust the appropriate height according to needs. When the plate on the upper side is aligned with the other two side plates, the vertical pressing component can fix the plate on the upper side of the support platform 3, and the staff can weld the three plates at the same time.

[0028] After the welding of the three plates is completed, when the unwelded semi-finished air box needs to be moved, first release the vertical pressing assembly, and the transmission assembly can control the rotation of the screw rod 14 to make the slider 13 slide to the side away from the pressing side plate 11, so that the pressing side plate 11 is opened to the outside and the plates on the side are released. Then, the semi-finished air box composed of three plates is dragged to the right front side and rotated to the back side, and the previous operation is repeated. At this time, two new plates can be placed again on the upper side of the rotating wheels 6 of the two sets of vertical fixing devices, and the other side of the air box can be welded.

[0029] The cooperation of the two sets of vertical fixing devices and the support platform 3 enables the gas box to fix multiple plates at the same time during welding. The cooperation of the universal ball 4, the vertical roller 29 and the rotating wheel 6 not only provides support for the plates in the vertical direction, but also facilitates the staff to adjust the position of the gas box plates, thereby improving the convenience of equipment use. The hydraulic rod 2 is driven by hydraulic pressure to realize the up and down movement of the support platform 3 to meet the welding requirements of gas boxes of different sizes or heights. The vertical roller 29 can tighten the plates to press the side plates 11 through the tensioning spring to prevent the movement or deformation of the gas box plates during welding, thereby improving the welding accuracy of the equipment. The vertical pressing assembly and the control assembly can quickly fix the plates of the welded gas box. The cooperation of the slide rail 12, the slider 13, the screw rod 14 and the hinged pressing side plate 11 can quickly release the plates. At the same time, with the cooperation of the universal ball 4, it is also convenient to move the partially welded gas box semi-finished product as a whole, reducing the time and labor intensity of manual handling and adjustment, and further improving work efficiency.

[0030] The vertical pressing assembly includes a C-shaped arm 15, which is fixedly installed on the left rear side of the base 1. A screw rod 16 is vertically rotatably installed on the upper side of the C-shaped arm 15. The screw rod 16 is threadedly connected to the C-shaped arm. A crank 17 is fixedly installed on the top of the screw rod 16, and a pressing plate 18 is rotatably installed on the bottom of the screw rod 16.

[0031] By rotating the crank 17, the screw 16 drives the pressing plate 18 to descend, thereby firmly pressing the gas box vertically to ensure the stability of the gas box during welding. At the same time, the crank 17 and the screw 16 also make the structure of the vertical pressing assembly simple and reliable, and easy to operate, thereby reducing its maintenance cost and improving ease of use.

[0032] The transmission assembly includes two rotating rods 19, both of which are rotatably connected to the base 1, one of the rotating rods 19 is transmission-connected to the screw rod 14 on the right side, and the axes of the two coincide with each other, the other rotating rod 19 is transmission-connected to the screw rod 14 on the front side, and the axes of the two coincide with each other, the left side of the rotating rod 19 on the right side and the rear side of the rotating rod 19 on the front side are concentrically fixed with the same bevel gear 20, the two bevel gears 20 are meshed with each other, a motor 21 is installed on the upper side of the base 1, the output end of the motor 21 is transmission-connected to one of the rotating rods 19, and the threads of the two screw rods 14 are the same and in opposite directions.

[0033] The slider 13 is driven to move on the slide rail 12 through the screw rod 14, thereby driving the pressing side plate 11 to limit and release the air box side plate in the vertical direction. The motor 21 and the bevel gear 20 transmission system in the transmission assembly realize the synchronous and reverse movement of the screw rods 14 on both sides, so that the two groups of pressing side plates 11 can operate synchronously, allowing them to work simultaneously according to the predetermined trajectory and speed, thereby improving the operating efficiency of the overall system, as well as improving the convenience and accuracy of operation.

[0034] There are two groups of control components and they correspond one to one with the two groups of vertical pressing components. The control components include push rods 22. The number of push rods 22 is the same as that of the support frame 7 and they are slidably connected to the left and right. One end of the push rod 22 is fixedly connected to a block 24 that matches the vertical roller 29. The other end of each group of push rods 22 is commonly fixed with a cross plate 23. An electric telescopic rod 25 fixedly connected to the base 1 is installed on the left side of the cross plate 23, and the output end of the electric telescopic rod 25 is transmission-connected to the cross plate 23.

[0035] The push rod 22, the block 24 and the electric telescopic rod 25 cooperate, and the control component is driven by the electric telescopic rod 25 to make the push rod 22 drive the block 24 to move, so that the card plate squeezes the vertical roller 29, thereby realizing the control of the rotation of the vertical roller 29. During the welding process, the roller can be locked or released as needed to meet different fixing requirements. At the same time, the control component structure is simple and its failure rate is reduced.

[0036] The outer side of the vertical roller 29 is covered with a rubber ring 27 .

[0037] The rubber ring 27 wrapped around the outside of the vertical roller 29 can increase the friction with the plate when the vertical roller 29 is fixed, and can also increase the friction between the vertical roller 29 and the block 24, so as to better fix the side plate and further improve the welding accuracy.

[0038] An anti-skid rubber block 26 is fixed to the bottom of the pressing plate 18 .

[0039] The anti-skid rubber block 26 at the bottom of the pressing plate 18 protects the air box plate at the top and increases the friction force to prevent the air box from sliding or being damaged during the pressing process.

[0040] An arc-shaped support plate 28 is installed on the left rear side of the base 1 , and the uppermost side of the arc-shaped support plate 28 is lower than the horizontal height of the rotating wheel 6 .

[0041] The arc-shaped support plate 28 can be used to provide auxiliary support for the plate that exceeds the vertical fixing device when the gas box plate to be welded is long, and can also prevent the gas box semi-finished product from sliding off the edge of the support platform 3 when the gas box semi-finished product is moved, thereby ensuring the safety and stability of the processing process. Ensure the safety and stability of the processing process.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
