Description

Technical Field

[0001] The utility model relates to the technical field of door leaf manufacturing, and particularly to a welding positioning tooling for door leaves. Background Art

[0002] When welding a spliced door, it is usually done by manually clamping the door leaf with a hand vise or a pipe wrench and then welding. For example, the form of single-point clamping and single-point welding is also used to perform multiple clamping and welding on the door leaf. It can be understood that the clamping convenience of the door leaf becomes particularly important. The above welding scenario not only has low efficiency, but also the accuracy during welding cannot be guaranteed. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a welding positioning tooling for door leaves.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A welding positioning tooling for door leaves includes pressing blocks arranged at each splicing position of the door leaf. A clamping groove communicating with the end face is formed on the side wall of the pressing block. Ejecting members are arranged on both sides of the clamping groove of the pressing block, and the ejecting members on both sides cooperate to press the two connecting edges of the door leaf.

[0006] Preferably, a handle is arranged on the pressing block.

[0007] Preferably, an installation hole communicating with the clamping groove is formed on the side wall of the pressing block, and the ejecting member is arranged in the installation hole.

[0008] Preferably, the installation hole is a threaded hole, and the ejecting member includes a ball screw screwed into the installation hole.

[0009] Preferably, the handle is a screw screwed onto the pressing block.

[0010] Preferably, at least two pressing blocks are arranged at each splicing position of the door leaf.

[0011] Preferably, a chamber is further formed in the pressing block. The chambers of several pressing blocks at the same splicing position of the door leaf are connected and communicated through a connecting pipe, and the connecting pipe is connected to a flow path system.

[0012] Preferably, the chambers are distributed on both sides of the clamping groove, and the two chambers on both sides are connected and communicated.

[0013] Preferably, a connection groove communicating with the chamber is formed on the side wall of the clamping groove. The ejecting member includes an ejecting block elastically arranged in the connection groove. When the fluid path system pumps fluid into the connecting pipe, positive pressure is generated in the chamber, and the ejecting block is pushed to abut against the connecting edge of the door leaf.

[0014] The beneficial effects of the present utility model are as follows: During welding, a pressing block is placed at each splicing joint of the door leaf. The pressing block clamps the two connecting edges at the splicing joint through the clamping groove, and the two ejecting members on both sides of the clamping groove can apply a pressing force to the connecting edge, so as to drive the two connecting edges to be pressed together to realize the clamping of the splicing joint, and then the splicing joint can be welded. Compared with the prior art, the door leaf welding positioning tooling of the present utility model has a relatively simple structure, and can conveniently clamp each splicing joint of the door leaf at the same time, which not only improves the clamping efficiency, but also improves the welding accuracy accordingly.

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 5As shown in the figure, a welding positioning tooling for a door leaf includes a pressing block 2 provided at each splicing joint of the door leaf 3. Specifically, a clamping groove 5 communicating with its end face is formed on the side wall of the pressing block 2. Therefore, the two connecting edges at the splicing joint of the door leaf 3 can be initially inserted into the clamping groove 5, and the two connecting edges are constrained by the clamping groove 5 to achieve initial clamping. Moreover, ejecting members 6 are provided on both sides of the clamping groove 5 on the pressing block 2. When the two ejecting members 6 eject, they can drive the two connecting edges to be pressed together, and finally achieve clamping at the splicing joint of the door leaf 3.

[0023] As Figures 1 to 3 shown, in some embodiments, at least two pressing blocks 2 are provided at each splicing joint of the door leaf 3. For example, an example in which two pressing blocks are provided at each splicing joint is shown in the appendix Figure 1 The specific number of pressing blocks 2 provided at each splicing joint can be optimized according to the length of the splicing joint to achieve a better clamping effect. In this disclosure, the number of its settings is not limited.

[0024] For example, an installation hole 7 communicating with the clamping groove 5 is formed on the side wall of the pressing block 2, and the above-mentioned ejecting member 6 is arranged in the installation hole 7. Specifically, the installation hole 7 is a threaded hole, and the ejecting member 6 can be preferably a ball screw 4. The ball screw 4 is a prior art and will not be elaborated in this disclosure. Briefly speaking, when the two connecting edges at the splicing joint of the door leaf 3 are inserted into the clamping groove 5, the ball of the ball screw 4 can be pressed against the connecting edge under the action of the spring inside it, thereby driving the two connecting edges to be pressed together.

[0025] In a preferred example, a handle 1 is further provided on the pressing block 2. For example, the handle 1 can be a screw screwed on the end face of the pressing block 2. Through the screw, the pressing block 2 can be conveniently controlled to press into the two connecting edges and be pulled out from the door leaf 3.

[0026] As Figure 4 、 Figure 5 shown, in another embodiment, chambers 8 are formed on both sides of the clamping groove 5 in the pressing block 2, and the two chambers 8 in the same pressing block 2 are communicated. A connecting groove 10 communicating with the chamber 8 is formed on the side wall of the clamping groove 5. The above-mentioned ejecting member 6 preferably includes an ejecting block 11 elastically arranged in the connecting groove 10. For example, the ejecting block 11 can be elastically and sealingly connected in the connecting groove 10 through an elastic member such as a spring.

[0027] In addition, several pressing blocks 2 at the splicing position of the same door leaf 3 are connected to each other through a connecting pipe 9 to enable the connection of several chambers 8, and the connecting pipe 9 is also configured to be connected to a flow path system. For example, the flow path system can be a water storage tank and a water pump. The cooling water in the water storage tank can be pumped into the connecting pipe 9 through the water pump, and then flow into the chambers 8 of each pressing block 2 through the connecting pipe 9. During the welding process of the door leaf 3, a circulating flow path of fluid will be formed among the several chambers 8, the connecting pipe 9, and the flow path system, so as to achieve the heat dissipation effect of the heat generated during welding. It can be understood that the flow path system can not only generate the above-mentioned function of forming a circulating flow path, for example, it can also control the water pumping power of the water pump, so as to generate a positive pressure in the chamber 8, and then push the ejector block 11 to tightly press against the connecting edge of the door leaf 3 to realize the clamping effect on the splicing position of the door leaf 3.

[0028] It can also be imagined that in the solution where the ejector 6 is a ball screw 4, a chamber 8 can also be opened in the pressing block 2. At this time, the flow path system will only be used to generate the above-mentioned circulating flow path to achieve the heat dissipation effect.

[0029] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Any changes and variations made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
