DETAILED DESCRIPTION

[0027] Refer to the instruction manual Figure 1 To Attachment Fig.11 An automatic welding track clamping device of the utility model is described in detail below.

[0028] The utility model is an automatic welding track clamping device, which structure includes a clamping device body 5, a clamping wheel 1, a clamping wheel fixing frame 3, a connecting ring 2, an adjusting handle 4 and a fixing wheel 6, wherein the clamping wheel 1 and the fixing wheel 6 are respectively arranged at both ends of the clamping device body 5, the adjusting handle 4 is connected to the clamping wheel 1 through the connecting ring 2 and the clamping wheel fixing frame 3, and the clamping wheel fixing frame 3 is arranged on the clamping device body 5. The clamping device is tightly connected to the track 9 through the fixing wheel 6 and the clamping wheel 1.

[0029] The clamping device body 5 is the support of this clamping device, and other components are installed on the clamping device body 5 to realize the opening and closing of the clamping wheel 1. One side of the clamping wheel 1 is hinged to the clamping wheel fixing frame 3, and the other side is hinged to the connecting ring 2. The other end of the connecting ring 2 is hinged to the adjusting handle 4, and the top of the adjusting handle 4 is hinged to the clamping wheel fixing frame 3. In this way, the clamping wheel 1, the clamping wheel fixing frame 3, the connecting ring 2 and the adjusting handle 4 form a four-bar linkage. The connecting ring 2 is pushed forward or backward by the adjusting handle 4, and the other side of the connecting ring 2 drives the clamping wheel 1, and the clamping wheel 1 can move forward and backward according to the running direction of the adjusting handle 4. The other side of the clamping wheel 1 is connected to the clamping wheel fixing frame 3, so the clamping wheel 1 performs a fan-shaped movement with the connection point between the clamping wheel 1 and the clamping wheel fixing frame 3 as the center according to the running direction of the adjusting handle 4.

[0030] When the adjustment handle 4 is away from the clamping device body 5, the distance between the clamping wheel 1 and the fixed wheel 6 increases, and the clamping device is opened from the track 9. When the adjustment handle 4 is close to the clamping device body 5, the distance between the clamping wheel 1 and the fixed wheel 6 decreases.

[0031] like Figure 5 , Figure 6 As shown: the clamping wheel 1 includes a clamping wheel housing 11, a first bearing 12, a first rotating shaft 13, a first large wheel 14 and a first small wheel 15. The first rotating shaft 13 is arranged in the clamping wheel housing 11, and a first bearing 12 is arranged between the first rotating shaft 13 and the clamping wheel housing 11. The end of the first rotating shaft 13 extends out of the clamping wheel housing 11, and a first large wheel 14 and a first small wheel 15 are arranged from top to bottom. A clamping wheel walking groove 16 is formed between the first large wheel 14, the first small wheel 15 and the first rotating shaft 13. The first large wheel 14 is a V-shaped wheel with a bottom surface gradually tilted upward from the inside to the outside, so as to facilitate the track to slide in.

[0032] like Figure 7 , Figure 8 As shown: the fixed wheel 6 includes a fixed wheel housing 61, a second bearing 62, a second rotating shaft 63, a second large wheel 64, a second small wheel 65 and a gear 66. The second rotating shaft 63 is arranged in the fixed wheel housing 61. A second bearing 62 is arranged between the second rotating shaft 63 and the fixed wheel housing 61. The end of the second rotating shaft 63 extends out of the fixed wheel housing 61, and a second large wheel 64, a gear 66 and a second small wheel 65 are arranged from top to bottom. A fixed wheel walking groove 67 is formed between the second large wheel 64, the second small wheel 65 and the gear 66. The gear 66 cooperates with the teeth on the side of the track 9. The second large wheel 64 is a V-shaped wheel with a bottom surface gradually tilted upward from the inside to the outside.

[0033] like Figure 4As shown: the clamping wheel fixing frame 3 is connected to the clamping device body 5 through the guide shaft 7 and the reset spring 8. The guide shaft 7 and the reset spring 8 are arranged in the middle cavity of the clamping device body 5. The reset spring 8 is sleeved on the guide shaft 7. The clamping wheel fixing frame 3 and the clamping device body 5 are connected and fastened by the elastic force of the reset spring 8. The clamping wheel fixing frame and the clamping device body have a certain elastic force to protect the clamping wheel and the fixed wheel. After the force between the clamping wheel 1 and the fixed wheel 6 exceeds the elastic force of the reset spring 8, the clamping wheel fixing frame 3 starts to move away from the clamping device body 5 to protect the clamping wheel 1 and the fixed wheel 6 from damage.

[0034] The fixed wheel 6 is connected to the other side of the clamping device body 5. The fixed wheel 6 and the clamping wheel 1 form a clamping device. The relative position of the clamping wheel and the fixed wheel can be adjusted by adjusting the handle to clamp and open the track. The clamping device is opened by adjusting the handle 4 away from the clamping device body 5, and the clamping device and the automatic welding trolley are taken out from the track 9. At the same time, the clamping wheel 1 and the fixed wheel 6 are placed above the track 9. The clamping device and the automatic welding trolley can be fastened to the track 9 by adjusting the handle 4 close to the clamping device body 5, thereby realizing the installation of the clamping device and the automatic welding trolley.

[0035] The guide shaft 7 includes a guide shaft body 71, a first screw 72 and a second screw 73. The first screw 72 and the second screw 73 are respectively arranged at both ends of the guide shaft body 71. The end of the first screw 72 passes through the clamping wheel fixing frame 3 and is connected to the guide shaft body 71. One end of the reset spring 8 is against the end of the second screw 72.

[0036] The clamping device is placed above the track 9, and the track 9 is placed in the running groove of the clamping wheel 1 and the fixed wheel 6. The first large wheel at the bottom of the clamping wheel 1 uses a V-shaped wheel to ensure that the track falls completely into the clamping wheel, ensuring the smooth operation of the clamping device and the automatic welding trolley.
