Existing welding equipment often has the following problems when welding castings: First, the positioning and clamping of the castings are not stable enough, and they are prone to displacement during the welding process, affecting the welding quality and accuracy; second, the movement and adjustment of the welding slide is not flexible enough, making it difficult to meet the welding requirements of different positions and angles. Utility Model Content

[0003] The purpose of this utility model is to provide a casting welding slide table to solve the problems mentioned in the background art. To achieve the above objective, this application provides the following technical solution: a casting welding slide table, comprising:

[0004] A workbench is provided with a mounting plate, and a horizontal slide rail is provided on the side wall of the mounting plate. A slider is slidably connected on the slide rail, and a fixing plate is connected to the slider.

[0005] A cylinder is mounted on the mounting plate, and a protrusion is connected to the end of its piston rod. The protrusion is connected to the fixed plate, and the piston rod moves in a direction parallel to the slide rail. The cylinder drives the fixed plate to move along the slide rail.

[0006] A rotating shaft, one end of which is disposed in a bearing seat on the fixed plate, and the other end is connected to a boss, on which a welding gun is mounted;

[0007] A clamping device is provided on the worktable and includes a fixed base, a clamping block and a lead screw. The fixed base is U-shaped and has sliding grooves on its inner walls on both sides. The clamping block is slidably disposed on the sliding grooves on both sides and its top wall is fixedly connected to the lead screw. The lead screw is threadedly connected to the threaded hole on the top wall of the fixed base. The casting is clamped or released by the movement of the lead screw.

[0008] In a preferred embodiment, this technical solution also includes a windproof ring, which is disposed on the protrusion and located directly in front of the welding torch.

[0009] In a preferred embodiment, the present technical solution further includes a handle, which is disposed on the side wall of the boss and is used to rotate the boss.

[0010] In a preferred embodiment, this technical solution also includes a V-groove, which is located in the middle of the bottom of the fixing base and is opposite to the clamping block.

[0011] In a preferred embodiment, this technical solution further includes two stops, both of which are disposed on the mounting plate and are located at both ends of the piston rod stroke of the cylinder.

[0012] In a preferred embodiment, the present technical solution further includes a U-shaped block and a limiting plate.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] By incorporating a horizontal slide rail and slider structure, the fixed plate can slide smoothly on the slide rail, ensuring the stability and precision of the welding torch's movement during welding. This not only improves welding accuracy but also significantly enhances welding efficiency. A cylinder drives the fixed plate to move along the slide rail, with the piston rod moving parallel to the slide rail, ensuring linearity and smoothness of movement and avoiding the vibrations and deviations that may occur in traditional manual or mechanical drive methods. The rotating shaft allows the welding torch to rotate around the shaft, adapting to welding needs at different angles and positions, greatly enhancing the flexibility of welding operations. The clamping device design uses the rotation of a lead screw to clamp or release the casting, making operation simple, time-saving, and labor-saving. The fit between the "U"-shaped fixed seat and the sliding groove allows the clamping block to slide flexibly, adapting to castings of different sizes, reducing adjustment time, and improving work efficiency.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0026] To understand this application, it is necessary to understand its application scenario. In the welding process of many alloy steels, two components are often connected, so it is necessary to fix and fit component A and component B separately at the same time.

[0027] In order to solve the technical problems in the background art, such as Figure 1-5 As shown, this application provides a technical solution: a casting welding slide, characterized as follows:

[0028] The worktable 1 is the basic component of the entire welding slide, typically welded from high-strength steel plates, possessing sufficient rigidity and strength to withstand various external forces during the welding process. A mounting plate 2 is provided on the worktable 1, fixed to it by bolts or welding for mounting and securing other components. The mounting plate 2 is a key component of the welding slide, with horizontal slide rails 3 on its side walls. The slide rails 3 are typically linear guides, possessing high precision and rigidity to ensure smooth sliding of the slider 4. A slider 4 is slidably connected to the slide rails 3, and is connected to a fixed plate 5 by bolts or other connections, driving the fixed plate 5 to move along the slide rails 3. A cylinder 6 is mounted on the mounting plate 2, with a protrusion 7 connected to the end of its piston rod, which is connected to the fixed plate 5. The piston rod moves parallel to the slide rails 3, and the extension and retraction of the cylinder 6 drives the fixed plate 5 to move along the slide rails 3. One end of a rotating shaft 8 is housed in a bearing seat on the fixed plate 5, and the other end is connected to a boss 9, on which a welding torch 10 is mounted. The rotating shaft 8 is mounted on the fixed plate 5 via a bearing seat, allowing it to rotate freely and thus adjust the angle of the welding torch 10. A clamping device 11 is mounted on the worktable 1 and is used to clamp and release the casting. The clamping device 11 includes a fixed base 12, a clamping block 13, and a lead screw 14. The fixed base 12 has an "U"-shaped structure with grooves 15 on both inner walls. The clamping block 13 is slidably mounted on the grooves 15 on both sides, and its top wall is fixedly connected to the lead screw 14. The lead screw 14 is threaded into a threaded hole on the top wall of the fixed base 12. The rotation of the lead screw 14 moves the clamping block 13, thereby clamping or releasing the casting. The clamping device 11 has advantages such as simple structure, convenient operation, and large clamping force, and can meet the clamping requirements of different castings.

[0029] It should be noted that the wind shield 16 is mounted on the boss 9 and located directly in front of the welding torch 10. The wind shield 16 is typically annular or semi-annular in structure, with its inner diameter slightly larger than the outer diameter of the welding torch 10. This ensures that the welding torch 10 can rotate and move freely, while effectively blocking airflow in front of the welding torch 10. The main function of the wind shield 16 is to reduce the impact of wind on the welding torch 10 during welding. During welding, wind can cause defects such as porosity and slag inclusions in the weld, affecting welding quality. By setting up the wind shield 16, the direct impact of wind can be effectively blocked, ensuring the stability of the welding area and thus improving welding quality.

[0030] Furthermore, handle 17 is mounted on the side wall of boss 9 and is typically fixed by bolts, rivets, or welding. The position of handle 17 should be designed to facilitate manual rotation of boss 9 by the operator without interfering with the normal use of welding torch 10. The main function of handle 17 is to allow the operator to manually rotate boss 9, thereby adjusting the angle and position of welding torch 10. During welding, it is sometimes necessary to fine-tune the angle of welding torch 10 according to the requirements of the welding process or the shape of the workpiece. Handle 17 allows the operator to easily achieve this adjustment, improving the flexibility and adaptability of welding.

[0031] It should be noted that the V-groove 18 is located in the middle of the bottom of the fixed base 12, opposite to the clamping block 13. The V-groove 18 is typically V-shaped with its opening facing upwards, used to support and position the casting. The two side walls of the V-groove 18 are opposite to one side of the clamping block 13, forming a stable clamping structure. The main function of the V-groove 18 is to provide a stable support and positioning platform, keeping the casting stable during welding. Through the cooperation of the V-groove 18 and the clamping block 13, precise clamping and positioning of the casting can be achieved, preventing displacement or deformation of the casting during welding, thereby improving welding quality and accuracy. In addition, the V-groove 18 also plays a certain guiding role, making the clamping block 13 slide more smoothly and accurately within the slide groove 15. This design can reduce friction between the clamping block 13 and the fixed base 12, extending the service life of the equipment.

[0032] Furthermore, stop blocks 19 are mounted on the mounting plate 2 and are located at both ends of the piston rod stroke of the cylinder 6. Stop blocks 19 are typically block-shaped structures with sufficient strength and rigidity to withstand the impact forces on the piston rod during its movement. The position design of stop blocks 19 should ensure that the piston rod can contact stop blocks 19 when it reaches its limit position, thereby limiting the piston rod's stroke.

[0033] It should be noted that the U-shaped block 20 and the limiting plate 21 are important components of this utility model. They work in conjunction with components such as the stop block 19 and the fixing plate 5 to achieve precise limiting and guiding of the piston rod movement of the cylinder 6. Specifically, the U-shaped block 20 has a U-shaped structure, with one end connected to the fixing plate 5 and the other end connected to the protrusion 7, forming a stable connection structure. The U-shaped block 20 has a groove inside, which is used to accommodate the limiting plate 21, thereby achieving the function of limiting the movement of the piston rod. Both ends of the limiting plate 21 are connected to the stop block 19, and the limiting plate 21 is located in the groove of the U-shaped block 20. This design allows the limiting plate 21 to slide freely in the groove of the U-shaped block 20, while achieving precise limiting of the piston rod movement through its connection with the stop block 19.

[0034] It is worth noting that the guide rods 22 are mounted on the mounting plate 2, located on both sides of the piston rod of the cylinder 6, and parallel to the piston rod. The guide rods 22 are typically square in structure, possessing sufficient rigidity and strength to withstand the lateral forces exerted on the piston rod during movement. The protrusions 7 are engaged between the two guide rods 22, assisting in guiding the movement of the piston rod. The main function of the guide rods 22 is to assist the piston rod of the cylinder 6 in performing smooth and accurate linear movement. During the welding process, the piston rod needs to undergo frequent reciprocating motion; without the assistance of the guide rods 22, the piston rod may deviate or wobble.

[0035] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
