Description

Technical Field

[0001] The utility model relates to the technical field of chain welding, in particular to a welding positioning device for an attached plate conveyor chain. Background Art

[0002] In order to improve the conveying stability of the conveyor chain, additional plates are sometimes welded to the conveyor chain to increase the weight of the chain so that it can run more smoothly under high-speed or high-load conditions, avoiding problems such as relative sliding and displacement of the conveyor chain when conveying objects, thereby improving the reliability of chain conveying.

[0003] However, when welding attachment plates to conveyor chains, it is often necessary to manually place the chains on a welding table, and some chains are relatively heavy, which makes it more laborious to carry the chains. Moreover, since the chains are generally connected together by pins to rotate the chains one by one, the entire chain will rotate relative to each other. Therefore, each time an attachment plate is welded to one of the chain sections, the chain needs to be straightened so that the attachment plate can be more accurately positioned and welded to the side plate of the chain, which makes the efficiency of welding attachment plates to conveyor chains low. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a welding positioning device for an attached plate conveyor chain.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0015] The beneficial effects of the utility model are:

[0016] 1. By placing the conveyor chain on the first conveyor plate, the circularly moving slide plate cooperates with the connecting rod and the push rod to abut against the two pins of the conveyor chain front and back, so as to drive the conveyor chain to move along the length of the first conveyor plate, and the push rod is elastically pushed by the compression spring, so that the push rod can better cooperate with the connecting rod under the elastic action of the compression spring, and press and clamp the two pins back and forth to ensure the flatness of the conveyor chain during the transfer process, and will not overlap with each other, and the welding guns on both sides of the conveyor chain are used to weld the attached plates transferred by the second conveyor plate to the conveyor chain, so that the attached plates can be welded more accurately and quickly without manually straightening the conveyor chain, thereby improving the efficiency and effect of conveyor chain attached plate welding;

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] like Figures 1 to 6 As shown, a welding positioning device for an attached plate conveyor chain includes a first conveyor plate 1 and second conveyor plates 4 relatively arranged on both sides of the first conveyor plate 1, the first conveyor plate 1 and the second conveyor plate 4 are at the same horizontal height, the first conveyor plate 1 is used to transfer the conveyor chain 11, and each section of the conveyor chain 11 is connected by a pin 12, and the second conveyor plate 4 is used to transfer the attached plates, that is, attached plates are transferred on both sides of the conveyor chain 11.

[0029] The first conveying plate 1 is provided with mounting plates 2 relatively distributed above and below. The mounting plate 2 is arranged above the first conveying plate 1. A movable slide plate 21 is provided on the mounting plate 2. The slide plate 21 is arranged on the mounting plate 2 for circular movement. The moving path direction of the slide plate 21 is consistent with the length direction of the first conveying plate 1.

[0030] The slide 21 includes a fixedly mounted connecting rod 22 and a slidingly mounted push rod 23. The push rod 23 and the connecting rod 22 are respectively abutted against two pins 12. The connecting rod 22 is fixedly mounted on the slide 21 and extends downward. The slide 21 is provided with a slide groove 211. The push rod 23 is slidably arranged in the slide groove 211 and extends downward. The push rod 23 and the connecting rod 22 of each slide 21 are arranged front and back and distributed on the moving path of the conveyor chain 11. That is, the push rod 23 of a single slide 21 abuts against the previous pin 12, and the connecting rod 22 abuts against the next pin 12 (reference Figure 1 In the direction shown, the conveyor chain 11 moves from right to left, and the push rod 23 of each slide 21 is on the left side of its connecting rod 22, that is, the push rod 23 is in front of its connecting rod 22).

[0031] refer to Figures 3 to 5 As shown, a compression spring 24 is installed between the push rod 23 and the connecting rod 22. The compression spring 24 drives the push rod 23 to slide away from the connecting rod 22 until the push rod 23 abuts against one end of the slide groove 211. The length direction of the slide groove 211 is parallel to the moving direction of the push rod 23, and the slide groove 211 provides guidance for the reciprocating sliding of the push rod 23.

[0032] refer to Figures 4 to 6 As shown, a shift rod 3 is rotatably installed on the mounting plate 2, and the shift rod 3 is set on the moving path of the push rod 23. The shift rod 3 presses the push rod 23 in the limited movement, so that the push rod 23 is pressed and squeezes the compression spring 24, that is, the push rod 23 is driven to slide close to the connecting rod 22, and the distance between the push rod 23 and the connecting rod 22 is reduced, and the push rod 23 and the connecting rod 22 can be inserted between the two pin shafts 12, and then the two pin shafts 12 of the conveyor chain 11 are abutted front and back through the cooperation of the connecting rod 22 and the push rod 23 to drive the conveyor chain 11 to move along the length of the first conveyor plate 1, that is, the automatic transportation and transfer of the conveyor chain 11 is realized, and there is no need for manual placement and transportation of the conveyor chain 11, thereby improving the welding efficiency of the conveyor chain 11.

[0033] Furthermore, the first conveying plate 1 is provided with a loading section 14 extending obliquely upward, and the shift rod 3 is arranged close to the loading section 14, and the conveying chain 11 is moved obliquely upward through the loading section 14, so that the support rod 23 and the connecting rod 22 can be more reliably inserted between the two pin shafts 12.

[0034] At the same time, as the push rod 23 continues to move until the push rod 23 squeezes over the gear rod 3, the push rod 23 slides away from the connecting rod 22 under the reaction force of the compression spring 12, until the push rod 23 slides to the pressing pin 12, and cooperates with the connecting rod 22 to clamp and fix the two pins 12, so as to achieve clamping and conveying of the conveying chain 11 through the pin 12, and the elasticity of the compression spring 124 pushes the push rod 23, so that the push rod 23 can better cooperate with the connecting rod 22 under the elastic action of the compression spring 124, and press and clamp the two pins 12 from front to back, to ensure the flatness of the conveying chain 11 during the transfer process, so as to improve the smooth transfer effect of the conveying chain 11, and there will be no stacking, which will affect the subsequent welding and attachment operations of the conveying chain 11.

[0035] A compression spring 2 31 is connected to one side of the gear lever 3, and the gear lever 3 presses the push rod 23 through the compression spring 2 31. A fixing plate 32 is fixedly installed on the mounting plate 2. One end of the compression spring 2 31 is fixed on the gear lever 3, and the other end of the compression spring 2 31 is fixed on the fixing plate 32. The gear lever 3, the compression spring 2 31, and the fixing plate 32 are distributed in sequence along the moving path of the push rod 23. As the slide plate 21 moves, the compression spring 1 24 of the push rod 23 is squeezed to the extreme position. At this time, the push rod 23 squeezes the gear lever 3 in the reverse direction so that the push rod 23 can be squeezed over the gear lever 3.

[0036] As the slide 21 moves further, the connecting rod 22 located on the rear side of the push rod 23 moves and abuts against the gear rod 3. The connecting rod 22 presses the gear rod 3, causing the gear rod 3 to compress the compression spring 2 31, so that the gear rod 3 can rotate so that the connecting rod 22 can squeeze over the gear rod 3, so that the connecting rod 22 and the push rod 23 can cooperate with each other to drive the conveyor chain 11 to move.

[0037] A welding gun 5 is provided on the outside of the side plate 13 of the conveyor chain 11. The welding gun 5 is used to weld the attachment plate to the side plate 13. The welding gun 5 on both sides of the conveyor chain 11 is provided to weld the attachment plate transferred by the second conveyor plate 4 to the conveyor chain 11. Therefore, there is no need to manually straighten the conveyor chain, and the attachment plate can be welded more accurately and quickly, thereby improving the efficiency and effect of welding the attachment plate of the conveyor chain 11.

[0038] Furthermore, the second conveyor plate 4 is provided with a conveyor box 42 for placing the attachment plate and a push rod 43 corresponding to the welding gun 5. The moving path of the conveyor box 42 is arranged parallel to the moving path of the conveyor chain 11. There are two push rods 43 and they are distributed on both sides of the conveyor chain 11. A driving member 431 is installed on the second conveyor plate 4. The output end of the driving member 431 is connected to the push rod 43 to drive the push rod 43 to move back and forth. The push rod 43 can push the attachment plate on the conveyor box 42 to abut the side plate 13, and weld the attachment plate to the side plate 13 through the welding gun 5. The attachment plate welding through the welding gun 5 is the first welding to ensure that the attachment plate will not fall off the side plate 13.

[0039] The second conveying plate 4 is provided with an inclined section 41 extending obliquely downward, and the inclined section 41 is staggered with the first conveying plate 1. A second welding gun 6 is provided on the rear side of the inclined section 41. The inclined inclined section 41 can prevent the second conveying plate 4 from interfering with the welding operation of the auxiliary plate, so that the second welding gun 6 can weld the auxiliary plate to the side plate 13 more firmly.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
