Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a replaceable fixture assembly used in welding workstations. Background Technology

[0002] A welding workstation is a work area or equipment combination specifically designed for welding operations. It typically includes welding equipment, auxiliary tools, workpiece fixing devices (such as fixtures), safety facilities, etc. The purpose of a welding workstation is to improve the efficiency and quality of welding operations while ensuring the safety of operators. When welding workpieces in a welding workstation, the use of fixtures is indispensable. Fixtures can be used to ensure that the workpiece does not move during the welding process, thus ensuring welding accuracy and consistency.

[0003] Chinese patent discloses a welding fixture for a welding workstation (authorization announcement number CN221755190U). This patented technology uses a disc, connecting plate, first screw, rotating shaft, limiting member, and spring. By rotating the screw, the distance between the C-shaped plates is adjusted, and the welding part and the C-shaped plate rotate around the rotating shaft and disc, flipping the welding part to facilitate welding the bottom of the welding part. When the welding part is thick, it can be directly flipped, improving the practicality of the device. The tension of the spring is used to position the rear end of the limiting member with the rotating shaft, keeping the welding part stable. By setting a connecting block, connecting rod, pressure plate, second screw, and adjusting cylinder, rotating the adjusting cylinder drives the second screw to move downward. The pressure plates on the front and rear sides can actively generate a height difference according to the thickness of the welding part, which is convenient for fitting the top of the welding part.

[0004] However, most existing welding workstations use a one-piece fixture design, which makes it impossible to replace the fixture when it is damaged, affecting welding operations. As in the aforementioned comparative document, which uses a one-piece fixture, repeated use during welding operations can lead to damage. Since the fixture is a one-piece design, it cannot be disassembled and replaced, further hindering welding work. Therefore, those skilled in the art have provided a replaceable fixture assembly for welding workstations to solve the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable fixture assembly for use in welding workstations, which can solve the problems mentioned in the background art.

[0021] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-3 As shown, a replaceable clamp assembly for use in a welding workstation includes a bracket 1. Cylinders 31 are symmetrically arranged on the outer side of the bracket 1, and connecting plates 3 are symmetrically arranged on the inner side of the bracket 1. A second guide rod 32 is symmetrically arranged on one side of the connecting plate 3 near the bracket 1, and a clamping part 2 is installed on the other side of the connecting plate 3. A first guide rod 22 is provided through the upper surface of the clamping part 2, and a pressure plate 21 is provided inside the clamping part 2. A screw 24 is provided at the middle position of the upper surface of the clamping part 2, and a mounting rail 23 is provided on one side of the clamping part 2. This arrangement allows the connecting plate 3 to move inside the bracket 1 when the cylinders 31 are in operation, thereby accommodating the clamping of different workpieces. The clamping part 2 slides inside the mounting groove 33 via the mounting rail 23, which facilitates the disassembly and replacement of the clamping part 2 and provides good practicality.

[0023] like Figure 3 As shown, two first guide rods 22 are symmetrically arranged on the upper surface of the clamping plate 21, and the upper end of the first guide rod 22 penetrates the upper surface of the clamping part 2. A bearing is provided at the middle position of the upper surface of the clamping plate 21. The screw 24 is provided with external threads and is threadedly connected to the clamping part 2. The lower end of the screw 24 is embedded in the bearing. This arrangement utilizes the threaded connection between the screw 24 and the clamping part 2 so that when the screw 24 rotates, the clamping plate 21 will move downward and be guided by the first guide rod 22, thus achieving the purpose of clamping the workpiece placed inside the clamping part 2.

[0024] like Figure 1 and Figure 2As shown, the mounting rail 23 is T-shaped. One side of the connecting plate 3 has a mounting groove 33 that slides with the mounting rail 23. One side of the connecting plate 3 has a bolt, and one side of the mounting rail 23 has a screw hole. One end of the bolt is embedded in the screw hole and threadedly connected to the screw hole. This design utilizes the sliding of the mounting rail 23 within the mounting groove 33 to achieve quick guiding installation of the clamping part 2 and the connecting plate 3. The connection between the connecting plate 3 and the clamping part 2 is achieved by connecting the bolt and the screw hole.

[0025] like Figure 1 As shown, the fixed end of the cylinder 31 is installed on the outer side of the bracket 1, and the telescopic end of the cylinder 31 is connected to one side of the connecting plate 3. This arrangement allows the connecting plate 3 to move inside the bracket 1 when the cylinder 31 is in operation, thereby satisfying the purpose of clamping workpieces of different sizes.

[0026] The working principle of this utility model is as follows: When using the replaceable fixture assembly of the welding workstation, the connecting plate 3 and the clamping part 2 are first installed. During installation, the mounting rail 23 on one side of the clamping part 2 can be slidably installed into the inside of the mounting groove 33. After installation, the clamping part 2 and the connecting plate 3 can be installed by inserting one end of the bolt into the screw hole and connecting it with the screw thread. In this way, the clamping part 2 can also be disassembled for replacement to facilitate subsequent welding of the workpiece.

[0027] Simultaneously, the operation of the cylinder 31 on the outside of the bracket 1 causes the connecting plate 3 to move inside the bracket 1, and the second guide rod 32 guides the movement, thus adjusting the position of the connecting plate 3 to accommodate different workpieces. The structure is simple and can achieve the purpose of automatic position adjustment.

[0028] The electrical equipment used in this invention is a known existing device that is connected to an external main controller and power supply. The main controller can be a computer or other conventional known device that can be used for control, and all of these can be purchased and used directly on the market. Their structure, circuit, and control principle are all known existing technologies. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
