Detailed Embodiment

[0025] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0026] Embodiment 1:

[0027] As Figures 1 - 6As shown, a solder joint peeling device applicable to irregular vehicle body panels includes an insertion head 1 and a crowbar 2. The insertion head 1 is used to insert into the space between the irregular vehicle body panels. During operation, a hammer is used to strike the insertion head 1 to ensure that the insertion head 1 can be inserted into a small space. The insertion head 1 is provided with a positioning groove 11, and the positioning groove 11 is used for the insertion of the crowbar 2. The crowbar 2 is inserted into the positioning groove 11 through the insertion portion 21. After insertion, the irregular vehicle body panels are separated by the crowbar 2.

[0028] In the prior art, the design of the crowbar 2 during the solder joint peeling process is relatively single. When encountering some panels with relatively tight connections on the vehicle body, it is not easy to insert into the space between them. In view of this, the working principle of the present utility model is to utilize the cooperation of the insertion head 1 and the crowbar 2 to achieve the peeling of the solder joints of the irregular vehicle body panels. First, the insertion head 1 is designed to insert into the narrow space between the irregular vehicle body panels. During the working process, the operator can use a hammer or other heavy objects to strike the insertion head 1 to ensure that it can be firmly inserted into a smaller space. The insertion head 1 is particularly designed with a positioning groove 11, and the purpose of the positioning groove 11 is to allow the crowbar 2 to be accurately inserted therein. When the crowbar 2 enters the positioning groove 11 through its insertion portion 21, the operator can utilize the lever force of the crowbar 2 to separate the irregular vehicle body panels. The whole process is through the physical lever principle, with the cooperation of the insertion head 1 and the crowbar 2, to achieve the effective peeling of the irregular solder joints.

[0029] Such as Figures 1 - 4 : The positioning groove 11 is provided with a positioning hole 12, and the insertion portion 21 is provided with a limit block 22. The limit block 22 slides in a limit groove 23 provided on the insertion portion 21. The inner wall of the limit groove 23 is provided with a moving groove 231. The limit block 22 is fixedly connected with a moving block 221 that moves in the moving groove 231. A guide rod 24 is provided in the limit groove 23. The limit block 22 is provided with a guide groove 25 for the guide rod 24 to pass through. Through the limitation of the guide groove 25, the limit block 22 moves along the axial direction of the guide rod 24. A return spring 241 is provided on the guide rod 24. After the insertion portion 21 of the guide rod 24 is inserted into the positioning groove 11, the limit block 22 passes through the positioning hole 12 to prevent the crowbar 2 from disengaging from the positioning groove 11.

[0030] The working principle of the device further refines the cooperation mechanism between the positioning groove 11 and the insertion part 21 of the crowbar 2 to ensure the stability and accuracy of the crowbar 2 during operation. The positioning groove 11 is provided with positioning holes 12, and the insertion part 21 of the crowbar 2 is equipped with a limit block 22. This limit block 22 can slide within the limit groove 23 on the insertion part 21. The inner wall of the limit groove 23 is further designed with a moving groove 231, allowing the moving block 221 on the limit block 22 to move therein. A guiding rod 24 is also provided within the limit groove 23, and the limit block 22 has a guiding groove 25 that matches the guiding rod 24. Through the limitation of the guiding groove 25, the limit block 22 can move along the axial direction of the guiding rod 24. To ensure that the limit block 22 can be reset smoothly, a return spring 241 is installed on the guiding rod 24. When the insertion part 21 of the guiding rod 24 is inserted into the positioning groove 11, the limit block 22 passes through the positioning hole 12. This design can effectively prevent the crowbar 2 from accidentally slipping out of the positioning groove 11 during use, thus ensuring the safety and reliability of the entire peeling process. Through this delicate design, the device can provide more precise and stable operation support in the solder joint peeling work of irregular vehicle body panels.

[0031] Such as Figure 5 and Figure 6 : It also includes a knocking block 3. The knocking block 3 includes an adapting block 31 and a knocking part 32. The adapting block 31 is used for the knocking block 3 to be inserted into the positioning groove 11, and the knocking part 32 is used for being knocked by a hammer. The knocking block 3 is used to avoid directly knocking and damaging the insertion head 1.

[0032] The device adds the design of the knocking block 3 to protect the insertion head 1 from being damaged during knocking. The knocking block 3 is composed of an adapting block 31 and a knocking part 32. The design of the adapting block 31 enables it to adapt to the positioning groove 11, ensuring that the knocking block 3 can be correctly inserted therein. The knocking part 32 is the part that bears the hammer knocking. Its design allows the operator to use a hammer to knock the knocking block 3 instead of directly knocking the insertion head 1. Through the intervention of the knocking block 3, the knocking force can be dispersed and absorbed, thereby reducing the direct impact on the insertion head 1 and avoiding damaging the insertion head 1 due to excessive knocking force. This design improves the durability of the device and the safety of operation, ensuring that the insertion head 1 can remain intact during the process of peeling the solder joints of irregular vehicle body panels and extending the service life of the device.

[0033] Such as Figure 5As shown, the crowbar 2 is available in multiple models with different lengths to expand the applicable range of the device. The device expands its applicable range by providing crowbars 2 of multiple models with different lengths. These different models of crowbars 2 allow the operator to select a crowbar 2 of an appropriate length according to the different space sizes between irregular body panels and the specific requirements for solder joint peeling. Through this design, the device can adapt to more types of body panels and effectively perform the solder joint peeling work in both narrow and wide spaces. This flexibility and adjustability greatly improve the practicality and versatility of the device, enabling it to be applied in a variety of different automotive repair and manufacturing scenarios.

[0034] Before the solder joint peeling of irregular body panels, one of the panels of the spot weld needs to be ground and thinned using an angle grinder. Grinding and thinning one of the panels of the spot weld using an angle grinder before the solder joint peeling is a pretreatment step of the device. The purpose of this step is to reduce the thickness of the panel, thereby reducing the force required for the crowbar 2 to insert and separate the panels, making the solder joint peeling process easier and safer. Grinding and thinning can reduce the hardness and strength of the panel, prevent excessive stress on the panel during the peeling process, and reduce the risk of damaging the panel or the crowbar 2. Through this pretreatment, the efficiency and success rate of solder joint peeling can be improved, and it also helps to protect the safety of the operator and avoid accidental injuries caused by excessive hardness of the panel.

[0035] Embodiment 2:

[0036] Compared with Embodiment 1, as Figure 1 and Figure 2 shown, a suspension opening 4 is provided at one end of the crowbar 2 away from the insertion part 21. The provision of the suspension opening 4 has practical convenience. When the crowbar 2 is not in use, it can be hung through the suspension opening 4, which is convenient for storage and access. Such a design helps to keep the working area tidy and reduces the risk of damage caused by the crowbar 2 rolling or sliding on the ground. In addition, the presence of the suspension opening 4 also facilitates the operator to quickly find and use the crowbar 2 when needed, improving work efficiency. The design of the suspension opening 4 takes into account the practicality and safety of the tool, making the entire solder joint peeling device more user-friendly and efficient.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
