[0027] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0028] Embodiment 1

[0029] Refer to Figure 1 , which is Embodiment 1 of a blanking device for welding parts of the present utility model, including a lifting mechanism 1, a translation mechanism 2, and a supporting component 3 for supporting welding parts; the supporting component 3 is power-connected to the lifting mechanism 1; the translation mechanism 2 is power-connected to the lifting mechanism 1.

[0030] Install the blanking device for welding parts of the present application in an automatic welding device. The lifting mechanism 1, the translation mechanism 2, and the supporting component 3 for supporting welding parts are all arranged below the welding parts. After the automatic welding device completes the welding of the parts, the lifting mechanism 1 can control the supporting component 3 to lift the welding parts to separate them from the fixture of the automatic welding device, and then the translation mechanism 2 drives the lifting mechanism 1 to move to positions such as the blanking conveyor belt or the placement rack in the subsequent process, that is, the blanking is completed. There is no need for manual blanking, which improves the blanking efficiency and reduces potential safety hazards. There is also no need for relatively expensive and large-sized devices such as robots and robotic arms, which reduces production costs and does not increase the occupied space.

[0031] In this embodiment, the supporting component 3 includes a base part 31 and a support rod 32; the support rod 32 is arranged on the base part 31, and the base part 31 is power-connected to the lifting mechanism 1.

[0032] Specifically, the base part 31 is a square pipe, and the support rods 32 can be arranged on the base part 31 according to the shapes of different welding parts to ensure that the support rods 32 can stably support the welding parts. The support rods 32 can be directly welded to the base part 31, or several support rods 32 can be welded together to form a shape adapted to the welding parts and then welded to the base part 31. By setting the base part 31 and all the support rods 32 on the base part 31, the lifting mechanism 1 only needs to drive the base part 31 to lift to drive all the support rods 32 to lift synchronously.

[0033] In this embodiment, the support rod 32 includes a bearing rod 321 and a stop rod 322. The bearing rod 321 is arranged on the base part 31, and the stop rod 322 is arranged at the end of the bearing rod 321 away from the base part 31 and extends upward.

[0034] Specifically, the end of the support rod 32 away from the base portion 31 is bent upward at a certain angle, thus forming a stop rod 322. The stop rod 322 can also be a separate rod, which is connected to the support rod 32 by welding. By providing the stop rod 322 at the end of the support rod 32, when the welding part is supported by the support rod 32, the stop rod 322 at the end of the support rod 32 can provide a block for the welding part to prevent the welding part from slipping off the support rod 32.

[0035] In this embodiment, the bearing rod 321 is provided with a buffer pad 33.

[0036] Specifically, the buffer pad 33 can be made of materials such as polyurethane, nylon or rubber. In this embodiment, polyurethane material is preferably used. The buffer pad 33 is arranged on the top surface of the support rod 32. By providing the buffer pad 33, the impact and friction when the support rod 32 abuts against the welding part can be reduced, and the wear of the welding part when it is supported by the support rod 32 can be prevented.

[0037] In this embodiment, the lifting mechanism 1 includes a lifting driving member 11 and a guiding assembly 12; the guiding assembly 12 is arranged on the lifting driving member 11; the supporting assembly 3 is arranged on the output end of the lifting driving member 11; both the lifting driving member 11 and the guiding assembly 12 are power-connected to the translation mechanism 2; the guiding assembly 12 is connected to the supporting assembly 3.

[0038] Specifically, the lifting driving member 11 can be an electric cylinder, a cylinder or a hydraulic cylinder. In this embodiment, a double-guide rod cylinder is selected. The guiding assembly 12 is used to provide a guiding effect for the movement of the supporting assembly 3. The translation mechanism 2 drives the guiding assembly 12 and the lifting driving member 11 to drive the supporting assembly 3 to translate. By providing the guiding assembly 12, when the lifting mechanism 1 drives the supporting assembly 3 and the welding part, the operation is more stable, the shaking of the supporting assembly 3 during lifting and moving is reduced, and thus the stability of the welding part on the supporting assembly 3 can be improved.

[0039] In this embodiment, an installation plate 13 is arranged on the output end of the lifting driving member 11, and the supporting assembly 3 is arranged on the installation plate 13; the guiding assembly 12 includes a guiding column 122 and a guiding block 121; the guiding column 122 is arranged at the bottom of the installation plate 13, and the extending direction of the guiding column 122 is the same as the output direction of the output end of the driving member; the guiding block 121 is movably inserted through the guiding column 122, and the guiding block 121 is power-connected to the translation mechanism 2.

[0040] Specifically, the base part 31 is welded to the top of the guide plate. The guide post 122 is vertically fixed to the bottom of the mounting plate 13 by bolts, and the output end of the lifting drive member 11 is also vertically fixed to the bottom of the mounting plate 13 by bolts. The guide block 121 is cylindrical, and the guide block 121 is coaxially sleeved on the guide post 122. The guide block 121 is connected to the translation mechanism 2. When the lifting drive member 11 operates, when the output end of the lifting drive member 11 drives the mounting plate 13 to move up and down, the guide post 122 slides up and down in the guide block 121 along with the movement of the mounting plate 13. Since the guide block 121 is connected to the translation mechanism 2, the guide block 121 is stationary relative to the guide post 122, thus playing a guiding role.

[0041] In this embodiment, the translation mechanism 2 includes a translation drive member 21 and a guide rail assembly 22; the lifting mechanism 1 is connected to the output end of the translation drive member 21 through the guide rail assembly 22.

[0042] Specifically, the translation drive member 21 is a rodless cylinder. The lifting drive member 11 and the guide block 121 are both connected to the guide rail assembly 22, and the guide rail assembly 22 is connected to the output end of the translation drive member 21. The translation drive member 21 drives the lifting drive member 11 through the guide rail assembly 22, and then drives the support assembly 3 and the welding parts on the support assembly 3 to move. The guide rail assembly 22 can not only share the weights of the lifting mechanism 1, the support assembly 3 and the welding parts, avoid stress concentration at the output end of the translation drive member 21 and damage, but also improve the stability of the lifting mechanism 1 during translation.

[0043] In this embodiment, the guide rail assembly 22 includes a slide rail 221 and a slider 222. The slider 222 is slidably disposed on the slide rail 221, and the stroke direction of the slide rail 221 is the same as the output direction of the output end of the translation drive member 21; the slider 222 is connected to the output end of the translation drive member 21, and the lifting mechanism 1 is connected to the slider 222.

[0044] Specifically, the slide rail 221 is installed parallel to the side of the translation drive member 21, and the slider 222 is slidably embedded on the slide rail 221. The output end of the translation drive member 21 is connected to the slider 222 through two connecting bars. The guide block 121 is connected to the slider 222 through a triangular connecting block, and the lifting drive member 11 is connected to the slider 222 through a triangular connecting block. When the output end of the moving drive member operates, the slider 222 is driven to move synchronously on the slide rail 221 through the connecting bar, and the slider 222 then drives the guide block 121 and the lifting drive member 11 to move synchronously.

[0045] Embodiment 2

[0046] Refer to Figure 1 and Figure 2, which is Embodiment 2 of a blanking device for welding parts of the present utility model. The difference between this embodiment and Embodiment 1 is that buffer members 4 are provided at both ends in the stroke direction of the slide rail 221.

[0047] Specifically, the buffer member 4 includes a base 41, a screw rod 42 and a striker rod 43. The base 41 is fixed to both ends in the length direction of the slide rail 221 by bolts. The screw rod 42 is inserted through the base 41 by thread fit. The striker rod 43 is slidably inserted into the screw rod 42. A spring is provided in the screw rod 42, and the striker rod 43 abuts against the spring. When the slider 222 moves too fast, the slider 222 hits the striker rod 43, and the striker rod 43 will compress the spring and move into the screw rod 42. At this time, the elastic force of the spring is opposite to the moving direction of the striker rod 43, that is, it can reduce the impact force of the slider 222 and achieve the buffering effect. By setting the screw rod 42, the screw rod 42 is inserted into the base 41 by thread fit, and the extended length of the screw rod 42 can be adjusted.

[0048] A flexible block 44 is installed at one end of the striker rod 43 away from the screw rod 42, and the material of the flexible block 44 is rubber. By setting the flexible block 44, the impact between the slider 222 and the striker rod 43 can be reduced, preventing damage to the slider 222 or the striker rod 43, and further improving the buffering effect on the slider 222.

[0049] Embodiment 3

[0050] Refer to Figure 3 , which is Embodiment 3 of a blanking device for welding parts of the present utility model. The difference between this embodiment and Embodiment 2 is that a dust-proof cover 5 is provided above the translation driving member 21. The dust-proof cover 5 is rectangular. The dust-proof cover 5 is supported above the translation driving member 21 by four support rods 32. There is an interval between the dust-proof cover 5 and the translation driving member 21 that can accommodate the connecting strip. When the automatic welding device welds parts, a lot of flying chips will be generated. If these flying chips enter the translation driving member 21, it is easy to have an adverse effect on the normal moving work of the translation driving member 21. By setting the dust-proof cover 5 on the translation driving member 21, it can prevent external dirt from entering the translation driving member 21 and ensure the normal operation of the translation driving member 21.

For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here.
