Description

Technical Field

[0001] The utility model belongs to the technical field of welding guns, and in particular relates to a protective gas testing tool and a welding gun kit for welding guns. Background Art

[0002] The existing protector anemometer for laser welding guns has a large docking distance with the welding gun, and the wind speed is easily affected by the surrounding air flow. The anemometer cannot be fixedly aligned with the gun head, and the wind speed and air volume of the welding gun cannot be calibrated stably, so stable measurement cannot be achieved. In addition, when the anemometer measures the wind speed, it is necessary to disassemble the gun head and adjust the relative position of the gun head and the anemometer each time, which takes a long time, so the process efficiency is low. Utility Model Content

[0003] In order to solve the above technical problems, the utility model discloses a protective gas test tool for a welding gun, which can quickly connect the anemometer and the welding gun, effectively avoiding the adverse effects of the external environment on the test results. The utility model also discloses a welding gun kit having the above protective gas test tool.

[0004] The specific technical solution of the utility model is as follows:

[0005] A protective gas testing tool for a welding gun, comprising:

[0006] A base body, wherein an air outlet is arranged on the base body;

[0007] A test docking rod, one end of which is connected to the base body, and the other end of which is used to connect to a welding gun; and

[0008] The anemometer is inserted into the base, and the testing part of the anemometer is located at one side of the air outlet.

[0009] The test docking rod can be directly connected to the welding gun, so that the shielding gas acts on the test part of the anemometer through the substrate, so that the test part of the anemometer can directly perform the shielding gas test, avoiding external factors interfering with the test results, thereby ensuring that the stable test purpose is achieved.

[0010] Preferably, the anemometer is provided with a connecting portion along its circumference;

[0011] The base is connected to the connecting part through a fixing piece 1 so that the anemometer can be assembled on the base.

[0012] The connecting part can be well matched through a fixing part, so that the anemometer and the base have a high connection stability. The structure is simple and easy to operate, and can facilitate the assembly between the line of sight anemometer and the base, while preventing the anemometer from producing circumferential rotation or axial displacement relative to the base.

[0013] Preferably, the connecting portion is a waist-shaped hole extending along the axial direction of the anemometer.

[0014] Since the connecting portion is configured as a waist-shaped hole, the axial displacement of the anemometer can be achieved during the process of assembling the anemometer to the base, so that the relative position between the anemometer and the base can be adjusted to meet actual use requirements.

[0015] Preferably, it also includes:

[0016] A clamping assembly is arranged on the end surface of the base body and is used to limit the anemometer in the axial direction of the base body.

[0017] The clamping assembly can improve the connection stability between the anemometer and the base, and further limit the anemometer in the axial direction.

[0018] Preferably, the clamping assembly comprises:

[0019] A clamping member, wherein the clamping member has a connection surface that fits the anemometer; and

[0020] A second fixing member is used to connect the clamping member and the base.

[0021] The clamping piece is wrapped around the outside of the anemometer to achieve clamping. On the basis of the second fixing piece, the clamping piece and the base are stably connected, thereby achieving a stable connection between the anemometer and the base, thereby meeting the tool's use stability requirements during the protective gas test.

[0022] Preferably, the clamping member comprises:

[0023] A plurality of clamping sub-bodies are arranged on the base along the circumference of the anemometer.

[0024] In addition to being able to well meet the requirements of the axis-limited anemometer, the structure can also limit the circumferential rotation of the anemometer, thereby better achieving the connection stability between the base and the anemometer.

[0025] Preferably, an insertion portion is provided at one end of the base, and the anemometer extends into the base from the insertion portion;

[0026] The base body is provided with a limiting piece at one end away from the inserting portion to limit the axial movement of the anemometer extending into the base body.

[0027] The limiting member can prevent the anemometer from excessive movement after the anemometer is inserted into the base, thereby providing a reference for adjusting the relative position between the anemometer and the base, so as to quickly place the test part on one side of the air outlet.

[0028] Preferably, it also includes:

[0029] A hose, one end of which is connected to the test docking rod, and the other end of which is connected to the base.

[0030] The hose can improve the spatial application range of the anemometer and avoid the inability of the test docking rod to align with the welding gun due to space limitations.

[0031] Preferably, the air outlet is located on the circumferential outer wall of the base body, and the gas flow direction through the air outlet is perpendicular to the axis of the anemometer.

[0032] On the basis that the test part is located on one side of the air outlet, the above structure can make the shielding gas blown out of the welding gun contact the test part better, thereby improving the test accuracy and better meeting the test requirements.

[0033] Welding gun kit, including:

[0034] A shielding gas test kit for a welding gun as described above; and

[0035] A welding gun is docked with the test fixture.

[0036] When the welding gun kit includes the above-mentioned test fixture and welding gun, it is possible to avoid disassembling the gun head of the welding gun when a shielding gas test is required, and there is no need to adjust the docking position between the welding gun and the test fixture, so that the test preparation work can be completed in a relatively short time, thereby improving production efficiency.

[0037] Compared with the prior art, the utility model can eliminate the influence of external factors caused by the gap between the welding gun and the anemometer, so that the test results are stable and the operation is simple, which can greatly reduce the risk of test quality; in addition, the utility model has a simple structure and is easy to assemble, which can improve the assembly efficiency, thereby effectively improving the process production efficiency.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0042] like Figure 1-2As shown, a protective gas testing tool for a welding gun includes a base 1, a test docking rod 2 and an anemometer 3; an air outlet 4 is provided on the base 1; one end of the test docking rod 2 is connected to the base 1, and the other end is used to connect to the welding gun 5; the anemometer 3 is inserted into the base 1, and its testing part is located on one side of the air outlet 4.

[0043] In this embodiment, the test docking rod 2 connected to the base 1 can quickly connect the welding gun 5, so that the shielding gas in the welding gun 5 can directly act on the anemometer 3 through the base 1, so that the anemometer 3 can obtain accurate measurement values. In the above process, there is no need to disassemble the gun head, nor to adjust the docking position between the welding gun 5 and the base 1. The anemometer 3 can be directly inserted into the base to meet the use conditions.

[0044] Specifically, the anemometer 3 is provided with a connecting portion 6 along its circumference; the base 1 is provided with a fixing member 7 connected to the connecting portion 6 so that the anemometer 3 can be assembled on the base 1. Further, the connecting portion 6 is a waist-shaped hole extending along the axial direction of the anemometer 3. When the anemometer 3 is assembled on the base 1, the relative position between the base 1 and the anemometer 3 can be adjusted by setting the waist-shaped hole. That is to say, in the specific assembly process, in order to align the test part of the anemometer 3 with the air outlet 4 and ensure that the protective gas can act well on the test part, the anemometer 3 can be adjusted axially. It should be noted that this adjustment is not a docking adjustment, and the above-mentioned required assembly purpose can be achieved through intuitive observation. Since the fixing member 7 is connected to the waist-shaped hole, in some cases, the anemometer 3 and the base 1 may accidentally move relative to each other in the axial direction. Therefore, in this embodiment, a clamping assembly is also included, which is arranged on the end face of the base 1 and is used to limit the anemometer 3 in the axial direction of the base 1. The anemometer 3 can be clamped on the base 1 by the clamping assembly to provide axial stability and prevent the anemometer 3 from moving relative to the base 1. The above assembly process can be to install the fixing member 7 first and then install the clamping assembly, or to install the clamping assembly first and then install the fixing member 7. It is known that if the clamping assembly is installed first, the clamping assembly can also prevent the anemometer 3 from rotating in the circumferential direction, so that when the fixing member 7 is assembled, a better stable assembly can be performed to ensure that the test part and the air outlet 4 are opposite, thereby ensuring that the protective gas can act well on the test part, and also preventing the protective gas from staying in the base 1 and causing adverse effects on the test results.

[0045] like Figure 1 and Figure 2As shown, in this embodiment, the clamping assembly includes a clamping member 8 and a fixing member 9; the clamping member 8 has a connection surface that fits the anemometer 3; the fixing member 9 connects the clamping member 8 and the base 1. Further, the clamping member 8 includes a plurality of clamping parts, and the plurality of clamping parts are arranged on the base 1 along the circumference of the anemometer 3. This structure makes the clamping process simple and easy to implement, and there is no need to forcefully bend the clamping member 8, so that it can avoid that the clamping member 8 cannot wrap the anemometer 3 effectively, thereby avoiding that the fixing member 9 cannot achieve the assembly purpose of limiting the position.

[0046] In this embodiment, an insertion portion is provided at one end of the base 1, and the anemometer 3 extends into the base 1 from the insertion portion; a limiter 10 is provided at one end of the base 1 away from the insertion portion to limit the axial movement of the anemometer 3 extending into the base 1. The setting of the limiter 10 enables the anemometer 3 to be located at a suitable position in the base 1 after being inserted into the base 1. Only appropriate adjustment is required to make the test part and the air outlet 4 relative to each other. In this embodiment, the air outlet 4 is located on the circumferential outer wall of the base 1, and the gas flow direction through the air outlet 4 is perpendicular to the axis of the anemometer 3. When the protective gas enters the base 1 through the test docking rod 2, it can directly act on the test part, and then leave the base 1 from the air outlet 4. In this process, the protective gas can act well on the test part, so that the test part obtains good test data, and due to the above-mentioned special structure, the protective gas can no longer stay inside the base 1, so that the protective gas cannot have an adverse effect on the test results on the basis that the external environment cannot affect the test results.

[0047] like Figure 1 As shown, in this embodiment, a hose 11 is further included, one end of which is connected to the test docking rod 2, and the other end is connected to the base 1. The test docking rod 2 and the hose 11 can be connected by threaded connection or clamping. Before testing, the hose 11 can be bent to provide a suitable docking position for the test docking rod 2 to dock the welding gun 5, ensuring a stable docking direction, thereby meeting the assembly requirements of the test tooling and the welding gun 5.

[0048] Therefore, based on the above embodiment, this embodiment also discloses a welding gun kit, such as Figure 1As shown, it includes the protective gas test fixture for the welding gun 5 as described above, and the welding gun 5; the welding gun 5 is docked with the test fixture. Therefore, through this embodiment, it is possible to well realize the measurement of the protective gas flow rate and flow velocity of the welding gun 5, eliminate the adverse factors affecting the measurement results, and use a simple structure to achieve efficient testing, which is conducive to improving production efficiency. At the same time, it can also be known that the anemometer 3 is fixed at one end of the base 1 by the clamping member 8 and the fixing member 2 9, and the anemometer 3 is also fixed by the fixing member 2 9 for rotation and translation, so that the anemometer 3 is stably fixed, which provides a prerequisite for stable measurement. Then, after the anemometer 3 and the welding gun 5 are connected, various influencing factors in measuring wind speed and air volume can be eliminated.

[0049] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
