Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically to a steel strip spot welding fixture. Background Technology

[0002] Steel strip spot welding is a type of resistance welding that uses cylindrical electrodes to form a weld point between the contact surfaces of two lapped workpieces. During welding, pressure is first applied to bring the workpieces into close contact, then current is applied, and the contact area melts under the action of resistance heat. After cooling, a weld point is formed. Steel strip spot welding is an efficient and important joining method, widely used in the lap joints of thin plate stampings, screens, spatial frames, and cross reinforcing bars.

[0003] The fixture used for spot welding is shown in the prior art disclosed in CN216541551U. Although this prior art uses a four-positioning method on both sides, and the two inner spring seat adjustment parts utilize the rectangular shape of the axle spring seats to achieve all-round positioning through four-sided contact, making the axle assembly more accurately positioned, and the positioning clamping parts on both outer ends press the two ends of the rear axle firmly to prevent the ends from lifting and bouncing during angle adjustment or spot welding, thus ensuring stable assembly and spot welding of the axle, this prior art lacks a structure for cooling the workpiece. This makes the workpiece susceptible to deformation due to temperature differences, which affects the practicality of the technical solution. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a steel strip spot welding fixture, which is connected to a gas supply device via a connecting pipe. This allows gas to be transported through the interconnected connecting pipe, gas supply pipe, conveying pipe, and transfer box to the inside of the output pipe. The output pipe then transports the gas to the top of the processing table and guides it to the welding area. This removes the heat generated during the spot welding process, thereby helping to ensure the shape and dimensional accuracy of the steel strip and improve the welding quality, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel strip spot welding fixture, including a processing table, wherein a clamping component for fixing the steel strip is installed on the top of the processing table;

A first electric push rod 10 is installed on the rear side of both the first support plate 7 and the rear side of the top of both the first support plate 7 and the rear side of the top of both the second support plate 8. A Z-shaped movable bracket 11 is rotatably connected to the rear side of both the first support plate 7 and the rear side of the top of both the first support plate 8. The rear end of the movable bracket 11 is connected to... The top of the first electric push rod 10 is rotatably connected; brackets 12 for fixing the welding gun are installed on both sides of the movable bracket 11 at the top of the first support plate 7 and on one side of the movable bracket 11 at the top of the second support plate 8; supports 13 for connecting the processing table 1 are installed on one side of the bottom of the first support plate 7 and one side of the bottom of the second support plate 8. The steel strip is supported by the clamping plate 9, and then the movable bracket 11 is rotated inward by the extension of the first electric push rod 10. The movable bracket 11 fixes and limits the top of the steel strip to ensure the stability of the steel strip when it is spot welded.

[0031] To facilitate the support and fixation of both ends of the steel strip, such as Figure 1 and 5 As shown, side support plates 14 are installed at the top of both ends of the processing table 1. Each side support plate 14 is rotatably connected to a pressure plate 15 at the rear of its top. A pressing plate 16 is installed at the bottom of the front end of the pressure plate 15, and a support plate 17 is provided at the bottom of the pressing plate 16. The support plate 17 is installed on one side of the top of the side support plate 14. A second electric push rod 18 is installed on the rear side of the side support plate 14, and the top of the second electric push rod 18 is rotatably connected to the rear end of the pressure plate 15. A side seat 19 for connecting the processing table 1 is installed on one side of the bottom end of the side support plate 14. The end of the steel strip is supported by the pressing plate 16, and then the extension of the second electric push rod 18 drives the pressure plate 15 to rotate inward. The pressure plate 15 limits and fixes the steel strip, thereby ensuring the stability of the steel strip when it is spot welded.

[0032] To improve the processing effect of steel strip, such as Figure 1 and 2As shown, the bottom of the processing table 1 is provided with an auxiliary component for air-cooling the steel strip; the auxiliary component includes an air supply pipe 2 located at the bottom of the front end of the processing table 1, both ends of the air supply pipe 2 extending to the bottom of the processing table 1, and the top of both ends of the air supply pipe 2 are fixedly connected to two spaced-apart conveying pipes 3, each conveying pipe 3 is provided with a transfer box 4 at the top, the top of the conveying pipe 3 is fixedly connected to the bottom of the transfer box 4, the top of the transfer box 4 is fixedly connected to multiple spaced-apart output pipes 5, the top of the output pipes 5 penetrates the processing table 1 and extends to the top of the processing table 1; a connecting pipe 6 for connecting an air supply device is fixedly connected to the front side of the air supply pipe 2.

[0033] The worker places the steel strip on the first support plate 7, the second support plate 8 and the two side plates, and then operates the controller 24 to start the first electric push rod 10 and the second electric push rod 18. The extension of the first electric push rod 10 drives the rotatably connected movable bracket 11 to rotate inward, thereby fixing the middle of the steel strip. The extension of the second electric push rod 18 drives the pressure plate 15 to move inward, thereby fixing both ends of the steel strip.

[0034] At the same time, the cylinder 21 is activated to drive the top plate 23 on the moving plate 22 to move upward. The top plate 23 supports and limits the bottom of the steel strip, thereby achieving the effect of limiting the steel strip in multiple directions and ensuring the stability of the steel strip when it is welded.

[0035] During spot welding, the worker connects to the gas supply equipment via the connecting pipe 6, and then the gas supply equipment delivers the gas through the connecting pipe 6 to the gas supply pipe 2. The gas supply pipe 2 then delivers the gas to the transfer box 4 via the delivery pipe 3, and then delivers the gas to the top of the processing table 1 via the output pipe 5. The output pipe 5 guides the gas to the welding area, which can remove the heat generated during spot welding, thereby helping to improve the shape and dimensional accuracy of the steel strip and improve the welding quality.

[0036] To facilitate support of the bottom of the steel strip, such as Figure 1 and 6 As shown, a fixed seat 20 is provided between the side seat 19 and the support 13.

The cylinder 21 pushes the top plate 23 on the movable plate 22 to move upward, and the top plate 23 supports the bottom of the steel strip, thereby ensuring the stability of the steel strip when it is spot welded.

[0037] To facilitate operation by staff, as shown in the figure, a controller 24 is installed on the top of one end of the processing table 1, and a support column 25 for connecting the processing table 1 is installed at the bottom of the controller 24. With the setting of the controller 24, it is convenient for staff to operate the first electric push rod 10, the second electric push rod 18 and the cylinder 21, thereby improving the convenience of operation for staff.

[0038] To ensure the stability of spot welding of steel strips, such as Figure 3 As shown, a contact plate 26 is installed at the bottom front end of the movable bracket 11 located on the second support plate 8, and a contact seat 27 is provided at the bottom of the contact plate 26. The contact seat 27 is installed at the top front end of the first support plate 7. Through the connection between the contact plate 26 and the movable bracket 11, when the movable bracket 11 drives the contact plate 26 to move inward, the contact plate 26 and the contact seat 27 cooperate to achieve the compression and limiting of the steel strip.
