DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with embodiments: Example

[0027] Combination Figures 1 to 9The illustrated welding tool for a scraper bucket comprises two mounting brackets 1, on which two adjusting rods 2 are slidably mounted along the length direction of the mounting brackets 1, and an adjusting plate 3 is sleeved on the outside of each adjusting rod 2, and the adjusting plate 3 rotates around the axis of the adjusting rod 2, and an extension rod 4 is slidably mounted inside each adjusting plate 3, and an extension plate 5 is sleeved on the outside of each extension rod 4, and the extension plate 5 rotates around the axis of the extension rod 4, and a bottom plate 9 of the bucket is placed on one of the extension plates 5, and a side wall inside the extension plate 5 is installed with a lever for driving the extension rod 4. Driving device, a first cylinder 6 is fixedly installed in each extension plate 5, and the output end of the first cylinder 6 is fixedly connected to an adjusting component 8, two groups of clamping components 7 for fixing the end of the base plate 9 are fixedly installed on each adjusting component 8, the adjusting component 8 is used to adjust the spacing between the two groups of clamping components 7 so that the two groups of clamping components 7 are used to assist in the assembly of the bucket, and a driving component for driving the two adjusting plates 3 to rotate is provided on the mounting bracket 1, and the driving component is used to drive the two groups of adjusting plates 3 to slide a corresponding distance along the length direction of the mounting bracket 1 after rotating a preset angle.

[0028] Specifically, in the existing technical solutions, various parts of the bucket need to be welded one by one to the corresponding parts of the bottom plate. In the process of splicing the bucket before welding, due to the large volume of the bottom plate, a variety of corresponding tooling is required for auxiliary assembly. In the prior art, the bottom plate is often turned over by crane hoisting, so as to facilitate welding of corresponding parts at various parts of the bottom plate. In the entire assembly and welding process, the bottom plate needs to be turned over many times, so this method of turning over the bottom plate occupies a large area and is limited in scope of application. In addition, because the crane and the bottom plate are often linked by chains, in the process of hoisting the bottom plate by the crane, The base plate shakes due to the instability of the connection, which can easily pose a threat to the surrounding construction equipment and even the construction personnel. In this embodiment, the base plate 9 to be processed is placed on one of the horizontal adjustment plates 3, and then the other adjustment plate 3 is driven to rotate to a preset angle by the driving component, and at the same time, the extension plate 5 is driven to gradually approach the back of the base plate 9 by sliding along the length direction of the mounting bracket 1 until the extension plate 5 fits the back of the base plate 9. The clamping components 7 in the two extension plates 5 are started to fix and lock the two ends of the base plate 9, so that the two extension plates 5 are fixedly connected to the base plate 9, and the base plate 9 is fixed in the device. When the base plate 9 needs to be flipped over (with Figure 1As an example), the two adjusting plates 3 are driven to rotate in the counterclockwise direction at the same time. During the flipping process of the bottom plate 9, the two extension plates 5 slide synchronously in the adjusting plate 3 with the flipping angle change of the bottom plate 9 to ensure that the clamping assembly 7 is always fixedly connected to the bottom plate 9. Until the bottom plate 9 is completely flipped, the clamping assembly 7 is released and the bottom plate 9 is assembled and welded. During the assembly and welding process, the spacing between the two clamping assemblies 7 can be adjusted by the adjusting assembly 8. The clamping assembly 7 in the non-working state is adjusted to a position that does not affect the welding, and then fixedly connected to the bottom plate 9. At the same time, since the welding points of each component are different, the fixed point between the clamping assembly 7 and the bottom plate 9 can be adjusted at any time according to the requirements of the welding point, so that the fixed connection between the clamping assembly 7 and the bottom plate 9 avoids affecting the welding operation. Furthermore, the clamping assembly 7 can even be started on one side of the welding point of each component to form a fixed connection between the clamping assembly 7 and the bottom plate 9. At the same time as the fixed connection, the clamping assembly 7 forms a limit baffle on one side of the welding point, and the parts to be spliced ​​can be directly welded against the clamping assembly 7, which plays an auxiliary calibration role and is convenient for the auxiliary assembly of parts such as bucket teeth, hanging ear plates, side plates, etc. The present invention adopts a double-plate clamping and flipping method to complete the flipping operation of the bottom plate 9. The overall fixing method is flexible and can adapt to bottom plates 9 of various models and sizes, and basically does not require manual auxiliary fixation. The bottom plate 9 is instantly locked by the clamping assembly 7, and can be directly released after the flipping is completed, so that the assembly process of the bucket will not be interfered with by the fixing device. Furthermore, the clamping assembly 7 can assist the calibration operation of the assembly, making the calibration between parts simpler and effectively improving the efficiency of the bucket processing operation. The overall size of the device is small, which is suitable for most bucket assembly operation scenarios, and basically gets rid of the manual auxiliary role when the bottom plate 9 is flipped, forming an effective protection for personnel and venues.

[0029] Furthermore, the adjusting assembly 8 includes a receiving frame 71 fixedly connected to the output end of the first cylinder 6, a synchronous plate 72 is fixedly installed at one end of the receiving frame 71 away from the first cylinder 6, a balancing rod 73 is installed through the synchronous plate 72, guide blocks 74 are fixedly installed at both ends of the balancing rod 73, and the two guide blocks 74 are slidably installed in the extension plate 5, the two guide blocks 74 are rotatably connected to the same bidirectional screw 76, the bidirectional screw 76 is threaded with two mounting blocks 75, and the other ends of the two mounting blocks 75 are slidably connected to the balancing rod 73, a first motor 81 is fixedly installed in the receiving frame 71, a main bevel gear 82 is fixedly installed at the output end of the first motor 81, a secondary bevel gear 83 is sleeved on the bidirectional screw 76, and the main bevel gear 82 is meshed with the secondary bevel gear 83.

[0030] Specifically, in the present embodiment, the adjusting component 8 is designed to adapt to base plates 9 of different sizes. The bidirectional screw 76 is driven to rotate by the transmission of the main bevel gear 82 and the secondary bevel gear 83 on the first motor 81, and the two mounting blocks 75 are driven to move toward or away from each other along the axial direction of the bidirectional screw 76 through the bidirectional screw 76. In addition, during the assembly of the bucket, when installing the side plates and the back plate, the clamping component 7 in the non-working state can be adjusted to the welding points of each component through the adjusting component 8, and then the clamping component 7 is started to form a fixed baffle at the welding point to assist the assembly of the bucket.

[0031] Furthermore, the clamping assembly 7 includes a plurality of limit rods 77 fixedly mounted on the mounting block 75, a same mounting plate 78 is fixedly mounted on the plurality of limit rods 77, a second cylinder 79 is fixedly mounted on the top of the mounting plate 78, the plurality of limit rods 77 are slidably connected to a same clamping plate 710, the output end of the second cylinder 79 is fixedly connected to the clamping plate 710, and an anti-slip pad is fixedly mounted on the bottom of the clamping plate 710.

[0032] Specifically, the clamping assembly 7 in this embodiment drives the clamping plate 710 to slide along the axis direction of the limiting rod 77 by the second cylinder 79 until the clamping plate 710 contacts the bottom plate 9 and fixes the bottom plate 9 to the extension plate 5. The two sets of clamping assemblies 7 move closer to or farther away from each other along the axis direction of the bidirectional screw 76. In addition to fixing the two ends of the bottom plate 9, they can also play an auxiliary positioning role when installing bucket teeth, hanging ear plates, side plates and other components in the bucket. For example, when installing bucket teeth, first, you need to A pair of bucket teeth is clamped on the bottom end of the base plate 9. After the bucket teeth are clamped, they need to be welded to the base plate 9. At this time, the clamping plate 710 is adjusted to the welding point between the bucket teeth and the base plate 9 in advance and the second cylinder 79 is driven to fix the clamping plate 710 to the base plate 9. The bucket teeth are placed against one side of the clamping plate 710 and the other side of the bucket teeth is welded to effectively improve the welding accuracy of the bucket teeth. Similarly, an avoidance groove for avoiding the ear plate is opened in the extension plate 5 to ensure that the ear plate can be assisted in welding when welding the ear plate.

[0033] Furthermore, a first sink 41 for accommodating the first cylinder 6 is provided in the extension plate 5 , and guide grooves 42 for accommodating the guide block 74 are provided on both sides of the extension plate 5 , and the guide block 74 reciprocates and slides along a preset direction of the guide groove 42 .

[0034] Specifically, in the present embodiment, the extension plate 5 and the adjustment plate 3 are connected by a unilateral rotation in order to facilitate the fit between the extension plate 5 and the base plate 9 when flipping. Since the length and rotation angle of the adjustment plate 3 are limited, the two adjustment plates 3 cannot always fit the base plate 9 during the flipping process of the base plate 9. Therefore, through the sliding extension and rotation adjustment of the extension plate 5, it is convenient to keep the clamping assembly 7 and the base plate 9 in a fixed and connected state.

[0035] Furthermore, the driving assembly includes a threaded rod 13 rotatably installed in the mounting bracket 1, and the mounting bracket 1 is provided with a first sliding groove 11 for installing the adjusting rod 2 and a receiving groove 12 for accommodating the threaded rod 13, the side walls of the mounting bracket 1 are fixedly installed with a second motor 14 for driving the threaded rod 13, the threaded rod 13 is threadedly connected with a first clamping block 15, and the first clamping block 15 is clamped on the adjusting rod 2 at one end away from the threaded rod 13, a second clamping block 16 for cooperating with the first clamping block 15 is slidably installed in the receiving groove 12, and the bottom of the second clamping block 16 is clamped with the adjusting rod 2, and the side wall of the first clamping block 15 is fixedly installed with a third motor 17 for driving the adjusting rod 2 to rotate.

[0036] Specifically, the adjusting rod 2 in the present embodiment is prone to tilt when sliding in the first slide groove 11, so it is necessary to limit the two ends of the adjusting rod 2 at the same time, so the first block 15 and the second block 16 can not only drive the adjusting rod 2 to slide in the mounting bracket 1, but also prevent the adjusting rod 2 from slipping in the two mounting brackets 1. When the adjusting plate 3 rotates, the two adjusting plates 3 are driven to slide along the length direction of the mounting bracket 1 by the second motor 14, and can further cooperate with the extension plate 5 to keep the bottom plate 9 in contact, so that the present device can be suitable for assembling buckets of more different sizes.

[0037] Furthermore, a second groove 21 for accommodating the extension plate 5 is provided in the adjustment plate 3 , and the depth of the second groove 21 is consistent with the thickness of the extension plate 5 . Second sliding grooves 22 for accommodating the extension rod 4 are provided on both sides of the adjustment plate 3 .

[0038] Furthermore, a driving device is installed in the second slide groove 22 for driving the extension rod 4 to slide back and forth along a preset direction of the second slide groove 22. Both ends of the extension rod 4 are equipped with a seat body that is slidably connected to the second slide groove 22, and the seat body is connected to the driving device. A driving motor for driving the extension rod 4 to rotate is fixedly installed on one side of the seat body.

[0039] Specifically, the driving component in this embodiment is a conventional existing technology. For example, the threaded rod 13 in the mounting bracket 1 drives the adjusting rod 2 to slide. Similarly, the same component can be installed in the extension plate 5 to drive the extension rod 4 to slide, thereby more accurately controlling the extension amount of the extension plate 5 to cooperate with the adjusting plate 3, so that the device can not only realize the flipping function of the bottom plate 9, but also accurately control the posture of the bottom plate 9 during the flipping process, so that the bottom plate 9 has more installation angles to choose from, and the seat body in the second slide groove 22 is used to assist the sliding of the extension rod 4 and limit its rotation angle by driving the motor, so that the rotation angle of the extension rod 4 can be adjusted to cooperate with the extension plate 5 to accurately control the flipping angle of the bottom plate 9.

[0040] Furthermore, a plurality of support plates 18 are fixedly mounted on the bottom of the mounting bracket 1 , and a telescopic device for adjusting the distance between the mounting bracket 1 and the ground surface is installed in the support plate 18 .

[0041] Specifically, in this embodiment, a telescopic device is used for the base of the device to facilitate loading and unloading of the base plate 9, to avoid more obstacles during loading and unloading due to the excessive height of the device, and to ensure that the height of the support plate 18 is sufficient to support the rotation of the adjustment plate 3 without colliding with the ground.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
