Description

Technical Field

[0001] The utility model relates to the technical field of welding machine equipment, in particular to a fixing fixture for a medium frequency welding machine. Background Art

[0002] The medium frequency welding machine controls the heat by the size of the current, applying a certain pressure and appropriate welding time during welding. The current is transmitted through the electrode head to the contact point of the welding workpiece to generate heat, heat the welding point, and complete the entire welding process.

[0003] In industrial production, medium frequency welding machines are a common welding equipment used to join two parts of a workpiece together. However, there is a problem in the design of existing medium frequency welding machines, that is, they are usually not equipped with a special fixture to fix the workpiece. This causes the operator to manually hold a part of the workpiece during the welding process and move the workpiece during the welding process to ensure that the area to be welded is located under the welding electrode head.

[0004] Due to the lack of fixture assistance, operators are easily disturbed by external factors during the welding process, such as hand fatigue, unstable workpiece movement, etc. These factors will cause hand shaking, which in turn affects the welding quality. In addition, the method of holding the workpiece for welding not only increases the difficulty of operation, but also requires complex workpiece positioning and alignment operations before each welding, which not only wastes the operator's time, but also reduces production efficiency.

[0005] In order to solve these problems, the industry needs to develop more advanced medium frequency welding machines. These devices should be equipped with fixtures that can fix the workpiece to reduce the operator's manual operation, reduce the impact of external factors, and improve welding quality and production efficiency.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original basis. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing fixture for a medium frequency welding machine, comprising a base, a support frame is connected to one side of the top of the base, and a welding unit is installed on the support frame, and a control box for driving the welding unit is connected to the support frame, and a carrying frame is connected to the other side of the top of the base below the welding unit, a working plate is installed on the top of the carrying frame, and a plurality of positioning blocks for positioning the workpiece are provided on the working plate, each of the positioning blocks is connected to a connecting plate on the outer side of the bottom, each of the connecting plates is installed with at least two bolts, and each of the positioning blocks is provided with a group of clamping structures for fixing and limiting the workpiece.

[0009] Preferably, the working plate is densely and evenly spaced with a plurality of through openings penetrating the upper and lower end surfaces thereof, and the through openings on the working plate are threadedly connected to the bolts.

[0010] Preferably, the positioning block is an inverted "L"-shaped structure when viewed from the side, and a rectangular structure when viewed from the top.

[0011] Preferably, the clamping structure includes a hydraulic chamber, a piston rod, a pressing plate, a main flow channel, an auxiliary flow channel, a fixed cylinder, a piston column, a screw, and a bonding plate. A hydraulic chamber is provided in the vertical area of ​​each positioning block, a piston rod is installed in each hydraulic chamber, and each piston rod end passes through the outer wall of the positioning block and is connected to a pressing plate. A main flow channel connected to the top of the hydraulic chamber is provided in the vertical area of ​​the positioning block, and an auxiliary flow channel connected to the main flow channel is provided in the horizontal area of ​​the positioning block. A fixed cylinder is connected to the bottom of the horizontal area of ​​the positioning block, and the fixed cylinder is connected to the auxiliary flow channel. A piston column is connected in each fixed cylinder, and a screw is threadedly connected to the lower end of each piston column, and a bonding plate is connected to the lower end of each screw.

[0012] Preferably, the piston rod is configured as a "T"-shaped structure, and the cross-section of the piston column is an inverted "concave"-shaped structure.

[0013] Preferably, the bottom of the laminating plate is provided with a wear-resistant rubber layer to prevent the workpiece from being scratched.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the fixing fixture for the medium frequency welding machine has the following advantages during welding work through the precise matching of the working plate, the positioning block, the connecting plate and the bolts; strong adaptability: according to the different shapes and sizes of the workpieces to be processed, the placement position and shape of the positioning block on the working plate can be adjusted and changed as needed by adjusting the bolts and the connecting plate to adapt to the positioning of workpieces of different shapes, thereby improving the flexibility and efficiency of processing.

[0015] Quick Positioning: Using this adjustment mechanism, the workpiece can be positioned quickly to ensure accuracy during the welding process.

[0016] Limitation function: Through the cooperation of the connecting plate and the bolts, the workpiece can be effectively restricted to prevent movement during the welding process.

[0017] Improve processing quality: Through precise positioning and limitation, it can ensure that the workpiece remains stable during the welding process, thereby improving the welding quality.

[0018] Adapt to mass production: In mass production, this adjustment mechanism can quickly adapt to the needs of different workpieces and improve production efficiency and economy.

[0019] Reduce processing time: Due to the automation of positioning and limiting processes, processing time can be greatly reduced and production efficiency can be improved.

[0020] In short, the device realizes the rapid and accurate positioning and limiting of the workpiece, thereby improving the efficiency and quality of the welding process, while increasing the flexibility and economy of the production process.

[0021] By setting the clamping structure, when the workpiece moves to fit the positioning block, it can trigger the clamping structure to extend, and work together with the working plate and the positioning block to achieve rapid clamping and fixing. After welding is completed, the clamping and fixing can also be quickly released, saving the time required for clamping and disassembling the workpiece, and significantly improving production efficiency. The clamping can be adapted and adjusted according to the size and thickness of different batches of workpieces, ensuring the versatility and practicality of the device. In addition, the setting of the rubber layer on the fitting plate avoids scratches on the workpiece during the clamping process. BRIEF DESCRIPTION OF THE DRAWINGS
