Description

Technical Field

[0001] The utility model belongs to the technical field of welding production, and in particular relates to a welding fixture carrier that is convenient for switching products. Background Art

[0002] When welding products, it is necessary to quickly replace products to improve work efficiency. After the products are removed, they need to be re-fixed on the welding fixture, which is cumbersome and wastes a lot of manpower time.

[0003] Patent announcement number CN218983712U is a welding fixture carrier that can automatically switch product types, including a mechanical arm and a welding gun, one end of the mechanical arm is connected to the welding gun; it is characterized in that: it also includes a servo motor, a reducer, a turntable carrier, a welding fixture and a base; there are two turntable carriers, located on one side of the mechanical arm, the turntable carrier is installed on the base, the servo motor is connected to the reducer and installed in the middle of the turntable carrier, and at least 2 welding fixtures are installed on each turntable carrier; each pair of welding fixtures has the same hole position on the turntable carrier. The above device only realizes the mechanical arm to weld different products by rotating the turntable carrier. It is difficult to accurately position during welding, and the product is prone to instability when placed on the turntable carrier. Therefore, it is urgent for technical personnel in this field to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to address the deficiencies of the above-mentioned prior art and to provide a welding fixture carrier that is convenient for switching products. The welding fixture carrier that is convenient for switching products drives the displacement component through the driving component to realize the clamping plate to clamp the product on the carrier. After the welding is completed, the driving component drives the displacement component to loosen the fixation of the clamping plate to the carrier. The operation is convenient, and different products can be quickly placed on the carrier.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The cam is an axially coupled machine which is adapted to engage the engagement of the engagement member with the engagement member and the engagement member and the engagement member are coupled to a pair of parallel rods, the pair of parallel rods being coupled to the engagement member and the engagement member being coupled to a pair of parallel rods.

[0007] By meshing the load-bearing gear with the transmission teeth in the first displacement rod and the second displacement rod, accurate transmission and positioning can be achieved, which is beneficial to the equipment for precise linear or rotational displacement control. The design of the two displacement rods can disperse the load-bearing capacity and the stress generated during movement, improve the stability and durability of the entire system, and avoid structural failure problems caused by excessive force on a single point. By driving the screw rod in coordination with the first connecting plate and the second connecting plate, the position of the second displacement rod can be flexibly adjusted as needed, thereby changing the working stroke or angle of the overall mechanism to meet different usage requirements. The various components cooperate with each other to form a highly integrated displacement system, which not only saves space but also is easy to install and maintain. Due to the gear meshing and screw rod transmission method, it has high transmission efficiency and self-locking performance, which can effectively prevent displacement changes caused by external forces while ensuring precise positioning.

[0008] Furthermore, the first connecting plate is arranged on the clamping plate at the head end of the base plate, and the second connecting plate is arranged on the clamping plate at the tail end of the base plate.

[0009] The first connecting plate and the second connecting plate are respectively arranged on the clamping plates at the head end and the tail end of the base plate. Such a symmetrical layout can enhance the structural stability of the entire device and ensure that no distortion or deformation occurs during displacement operation. The connecting plates at both ends fix the displacement assembly directly on the clamping plates, so that the power output from the driving screw rod can be more directly and effectively transmitted to the first displacement rod and the second displacement rod, thereby improving the transmission efficiency. In this way, whether at the starting position or the end position of the device, good connection rigidity and stability can be maintained, and it can better adapt to the operation requirements of different lengths or spans. The fixing method at both ends helps to simplify the assembly process. At the same time, when it is necessary to fine-tune the position according to the actual working conditions, the position of the displacement assembly can be indirectly changed by adjusting the clamping plate, which is more convenient to operate.

[0010] Furthermore, a connecting piece is provided at the bottom of the first displacement rod, and the first displacement rod is connected to the driving screw rod through the connecting piece.

[0011] The first displacement rod is connected to the driving screw by a connecting piece, which can accurately convert the rotational motion generated by the driving motor into linear displacement, making the movement of the clamping plate more precise, thereby ensuring the accuracy of the workpiece position during welding. The design of the connecting piece enhances the rigidity and stability of the structure, effectively avoiding problems such as looseness and wear that may be caused by direct connection, and improving the service life and working reliability of the entire device. If a component in the transmission system needs to be repaired or replaced, the existence of the connecting piece makes disassembly and assembly more convenient, without the need for large-scale disassembly of the entire equipment, greatly reducing maintenance costs and downtime.

[0012] Furthermore, the driving motor is fixed to the base plate by bolts, and the driving screw is also fixed to the base plate by bolts. A telescopic rod is provided at the rear end of the base plate, the telescopic rod is connected to the second connecting plate, and the telescopic rod is fixed to the base plate by bolts.

[0013] The drive motor and drive screw are fixed to the base plate by bolts, which can ensure their stability during operation and avoid loosening or deviation due to vibration and other reasons, thereby ensuring the normal operation and precise control of the transmission system. The use of bolt fixing makes the motor and screw easy to install and disassemble. When the motor or screw needs to be repaired or replaced, it is only necessary to loosen the bolts, which simplifies the maintenance process and reduces downtime. The telescopic rod set at the rear end of the base plate and the second connecting plate fixed by bolts enable the fixture carrier to be adjusted in length according to actual working conditions to meet the welding requirements of different sizes or special positions, while also increasing the flexibility and applicability of the equipment.

[0014] Furthermore, the bearing platform is connected to the middle fixing portion of the bearing gear via a supporting column.

[0015] By connecting with the support column, the weight of the workpiece on the load-bearing platform can be effectively dispersed to the load-bearing gear. The high strength and good load-bearing performance of the gear can be used to enhance the load-bearing capacity of the overall structure, ensuring stable load-bearing even when facing heavier workpieces during welding. The design of the support column can improve the stability of the load-bearing platform, reduce the risk of shaking or tilting caused by changes in the weight of the workpiece, and ensure the positioning accuracy of the workpiece during welding. If the load-bearing gear is part of the transmission system, then this connection method can convert the position change of the workpiece on the load-bearing platform into linear or rotational motion through the gear transmission mechanism, thereby achieving precise control, which is especially suitable for complex welding processes that require multi-axis linkage.

[0016] Furthermore, a sliding block is provided on the bottom plate, a sliding groove is provided on a side wall of the sliding block, and connecting grooves are provided on the bottom plates of the first connecting plate and the second connecting plate, and the connecting grooves are embedded in the sliding grooves.

[0017] The cooperation between the sliding block and the sliding groove provides a precise guiding function, ensuring that the first connecting plate and the second connecting plate move smoothly along the predetermined trajectory, avoiding deviation or shaking during work, and improving the operating accuracy of the equipment. The design of the sliding block greatly improves the stability of the welding fixture carrier, and by limiting the movement range and path of the connecting plate, ensures that the clamping plate moves smoothly and smoothly during clamping and releasing the workpiece, avoiding accidental damage to the workpiece. The contact surface between the sliding block and the connecting groove is generally hardened, which can effectively reduce friction and extend the service life of the equipment. At the same time, it reduces the problem of equipment accuracy reduction caused by wear. The mosaic design of the sliding block and the connecting groove makes the entire equipment compact and has high space utilization. It is also relatively simple and quick to clean, maintain or replace parts when necessary.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model drives the driving screw to feed by the driving motor, the driving screw is connected to the displacement assembly, the displacement assembly drives the clamping plate to clamp the product on the carrier, and the driving motor can be reversed to release the product on the carrier. The staff only needs to control the forward and reverse rotation of the driving motor to quickly clamp and release the product, and then quickly switch the processed product;

[0020] 2. Since the clamping plate and the connecting plate are connected by bolts, different clamping plates can be replaced according to needs to achieve clamping of more different types of products, thereby improving the versatility of the device. The bottom of the clamping plate is arranged in the groove of the sliding block, and there will be no difficulty in displacement after being driven by the driving assembly. The first connecting plate is engaged with the second connecting plate, thereby ensuring the precision of the transmission of the displacement assembly. BRIEF DESCRIPTION OF THE DRAWINGS
