Description

Technical Field

[0001] This solution relates to the field of machining, and specifically to a welding fixture for the outer scraper of a silage harvester. Background Art

[0002] A silage harvester is an agricultural machine used for harvesting silage feed, which can quickly harvest and chop crops such as corn and forage grass, greatly improving the harvesting efficiency and reducing the manual labor intensity.

[0003] In the structure of a silage harvester, the welding of the left and right outer scrapers is an important component of the cutter bar of the silage harvester. It is adjacent to the feeding wheel and is used to scrape the grass on the teeth of the feeding wheel. The outer scraper is a three-dimensional structure composed of many arc surfaces, vertical surfaces, flat surfaces and inclined surfaces, and there are welding points on both the front and back. There are many positioning points during welding, and before welding, some components are processed by existing welding fixtures for outer scrapers, mostly simple fixtures, which rely on manual positioning and clamping one by one, making it difficult to ensure quality and time-consuming and laborious in operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to achieve precise positioning of each component of a workpiece combined with arc surfaces, vertical surfaces, flat surfaces and inclined surfaces, and achieve the positioning of all workpieces with as few steps as possible.

[0005] The specific technical solution for this utility model to solve the above technical problem is as follows:

[0006] A welding fixture for the outer scraper of a silage harvester, comprising a base, a substrate, and a flipping device. The flipping device is fixedly arranged on the base, the substrate is arranged on the base through the flipping device, and the flipping device is used to control the substrate to achieve a 180° flip; a workpiece positioning component is arranged on the substrate.

[0007] The workpiece positioning component includes a bottom plate positioning component, a bottom plate clamping component, and a suspended plate positioning and clamping part.

[0008] The bottom plate positioning component includes a supporting surface, a limiting groove or a limiting vertical surface, which is used to position the horizontal and vertical positions of the bottom plate to be welded.

[0009] The bottom plate clamping component is used to clamp the positioned bottom plate to fix it in the positioned position.

[0010] The suspended plate positioning and clamping part is used to position and clamp the suspended plate to be welded, and further includes a suspended positioning driving part, which is used to drive the suspended plate positioning and clamping part to switch between a preparatory position and a working position.

[0011] Compared with the prior art, this solution has the following beneficial effects:

[0012] All participating welded parts are accurately positioned and clamped to ensure product quality;

[0013] The flipping device in this solution facilitates flipping of the workpiece to weld all weld seams;

[0014] A profiling positioning and clamping device is designed to facilitate accurate positioning, clamping, picking, and placing of parts;

[0015] A displacement positioning device driven by a push-pull type clamp is designed to facilitate positioning and picking and placing of suspended workpieces;

[0016] Furthermore, the bottom plate positioning assembly is detachably provided on the substrate.

[0017] The beneficial effect of adopting the above further solution is that the positioning plate assembly is detachably arranged, and positioning plates matching different specifications of products can be replaced, realizing the generalization of the tooling main body and saving production sites and manufacturing costs.

[0018] Furthermore, it further includes a detection pin assembly, and the detection pin assembly is arranged at the hole position with a fixed position on the workpiece to be welded for detecting whether the workpiece to be welded is positioned accurately.

[0019] The beneficial effect of adopting the above further solution is that it can ensure that the workpiece is positioned accurately. If the detection pin cannot be smoothly inserted to the bottom, it means that the workpiece is not accurately positioned and needs to be adjusted to ensure product quality.

[0020] Furthermore, the detection pin assembly also has the function of sending out electrical signals externally. When the detection pin is not in place, a signal of "positioning not in place" is sent out externally.

[0021] The beneficial effect of adopting the above further solution is that it can be linked and locked with other automatically controlled actuators to ensure the quality of the final product.

[0022] Furthermore, the bottom plate positioning assembly is fixed to the substrate through an adjustment reference block.

[0023] The beneficial effect of adopting the above further solution is that all bottom plate positioning assemblies are replaceable to adapt to different specifications of products, and the relative position between the adjustment reference block and the substrate is more accurate. Therefore, each bottom plate positioning assembly is positioned based on the adjustment reference block to ensure the accuracy of the positioning dimension.

[0024] Furthermore, a hollow area is provided on the substrate, and the bottom plate positioning assembly is arranged on the periphery of the hollow area or straddles above the hollow area.

[0025] The beneficial effect of adopting the above further solution is that the setting of the hollow area facilitates welding of the weld seams that originally need to be welded on the reverse side after flipping.

[0026] Furthermore, the hanging plate positioning and clamping member includes a support, the hanging positioning driving member is a push-pull type compactor, a fixing plate is provided at the telescopic shaft end of the push-pull type compactor, a hanging plate positioning plate is provided on the fixing plate, a diamond-shaped positioning pin and a conical positioning pin are provided on the hanging plate positioning plate, and a magnet is also embedded.

[0027] The beneficial effect of adopting the above further solution is that the hanging plate positioning and clamping member can switch between the preparation position and the ready position. When in the preparation position, there is a large operating space, which is convenient for fixing the workpiece to be welded onto the hanging plate positioning and clamping member. The built-in magnet can adsorb the workpiece to be welded to prevent the hanging member from falling off. After getting ready, the hanging plate positioning and clamping member acts, that is, the push-pull type compactor pushes the workpiece to be welded to the position waiting for welding and waits for welding.

[0028] Furthermore, a guiding seat is also provided on the support, a guiding column is slidably provided in the guiding seat, and the guiding column is fixedly provided on the fixing plate.

[0029] The beneficial effect of adopting the above further solution is that the setting of the guiding seat and the guiding column can further improve the running stability of the hanging plate positioning and clamping member, especially when the hanging member is relatively large, to avoid tilting during the movement process.

[0030] Furthermore, a positioning boss adapted to the workpiece to be welded is also provided on the hanging plate positioning plate.

[0031] The beneficial effect of adopting the above further solution is to further improve the stability of positioning.

[0032] Furthermore, the bottom plate clamping assembly is arranged on the substrate through an adjustment reference block, includes a bottom clamping seat plate and a clamping arm hinged to the bottom clamping seat plate and adapted to the workpiece to be welded, and also includes a locking mechanism for fixing the bottom plate clamping assembly in the clamping position.

[0033] The beneficial effect of adopting the above further solution is that the locking mechanism can firmly fix the bottom plate clamping assembly in the required position. Even if the entire substrate is flipped, it does not affect the relative positions of the workpieces, ensuring the stability of the processed product. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0067] As Figure 1 shown, it is a schematic diagram of the welding combination of the left and right outer scrapers of a certain model. It is a schematic diagram of the components that need to be fixed by this tooling, including the first outer scraper partition welding 91, the second outer scraper partition welding 92, the outer scraper mounting plate 93, the outer scraper connecting plate 94, the first reinforcing connecting plate 95, the second reinforcing connecting plate 96, the third reinforcing connecting plate 97, and the outer scraper guiding plate 98. A total of eight components need to be positioned and welded together; the first outer scraper partition welding 91 and the second outer scraper partition welding 92 have been welded together in other processes.

[0068] As Figure 3 shown, a welding tooling for the outer scraper of a silage machine includes a base 1, a substrate 2, and a flipping device 3. The flipping device 3 is fixedly arranged on the base 1, the substrate 2 is arranged on the base 1 through the flipping device 3, and the flipping device 3 is used to control the substrate 2 to achieve multi-angle flipping; a workpiece positioning component is arranged on the substrate 2.

[0069] As Figure 5 shown, the flipping device 3 includes a left frame 303 and a right frame 302. A connecting piece 301 is arranged on the right frame 302 through a spherical bearing 309. A speed reducer 306 is arranged on the left frame 303. The output end of the speed reducer 306 is fixedly connected to a dividing plate 307. A plurality of notches are arranged circumferentially on the dividing plate 307. A locking pin 304 is arranged beside the dividing plate 307.

A rocker arm 305 is also integrated on the speed reducer 306 for manual flipping. The output end of the speed reducer 306 is also fixedly connected to a second connecting piece 301 through a spherical bearing 309. The connecting piece 301 on the left frame 303 and the connecting piece 301 on the right frame 302 are used to install and carry the substrate 2.

[0070] In this example, this welding tooling includes two working stations on the left and right, and two sets of symmetrical mechanisms, which respectively correspond to processing the left outer scraper and the right outer scraper; only one set of mechanisms will be described in detail below as an example.

[0071] The workpiece positioning component includes a bottom plate positioning component 41, a bottom plate clamping component, and a suspended plate positioning and clamping member 403;

[0072] The bottom plate positioning component 41 is detachably arranged on the substrate 2. The bottom plate positioning component 41 includes a supporting surface, a limiting groove or a limiting vertical surface, which is used to position the horizontal and vertical positions of the bottom plate to be welded; the bottom plate clamping component is used to clamp the positioned bottom plate to fix it at the positioned position.

[0073] In this example, more specifically, as Figure 4 shown, it includes a first positioning component 400; a second positioning component 401; a third positioning component 402; and each bottom plate positioning component 41 is fixed to the substrate 2 via an adjustment reference block 6.

[0074] The suspended plate positioning and clamping member 403 is used for positioning and clamping the suspended plate to be welded, and further includes a suspended positioning driving member, and the suspended positioning driving member is used to drive the suspended plate positioning and clamping member 403 to switch between a preparatory position and a working position.

[0075] It further includes a detection pin assembly 5, as Figure 9 shown, the detection pin assembly 5 includes a detection base plate 501, a detection pin body 502 and a pin base plate 503. The pin base plate 503 is fixedly arranged on the detection base plate 501, and the detection pin body 502 is telescopically arranged in the detection base plate 501 via a spring. The detection pin assembly 5 is arranged at a hole position with a fixed position on the workpiece to be welded, and is used to detect whether the workpiece to be welded is positioned accurately. The detection pin assembly 5 is internally provided with a proximity switch so as to have the function of sending out an electrical signal outward. When the detection pin is not in place, it sends out a signal characterizing "positioning not in place" externally, which can avoid the action of each electric control actuator under the condition of inaccurate positioning and ensure the product quality.

[0076] As Figure 3 shown, a hollowed-out area 201 is provided on the substrate 2, and the bottom plate positioning component 41 is arranged on the periphery of the hollowed-out area 201 or straddles above the hollowed-out area 201.

[0077] As Figure 10 shown, the suspended plate positioning and clamping member 403 includes a support 4031, the suspended positioning driving member is a push-pull type compactor 4032, a fixing plate 4033 is provided at the telescopic shaft end of the push-pull type compactor 4032, a suspended plate positioning plate 4034 is provided on the fixing plate 4033, a diamond-shaped positioning pin 4035 and a conical positioning pin are provided on the suspended plate positioning plate 4034, and further includes a magnet 4037 embedded therein.

[0078] A guide seat 4038 is further provided on the support 4031, and a guide post 4039 is slidably arranged in the guide seat 4038.

[0079] A positioning boss 4030 adapted to the workpiece to be welded is further provided on the suspended plate positioning plate 4034.

[0080] The bottom plate clamping assembly is arranged on the substrate 2 via an adjustment reference block 6, and includes a bottom clamping seat plate 700 and a clamping arm 702 adapted to the workpiece to be welded and hinged to the bottom clamping seat plate 700; in this example, it includes three clamping assemblies, that is, asFigure 11 the first clamping assembly 71 shown; as Figure 12 the C-shaped clamp 72 shown and as Figure 13 the third clamping assembly 73 shown; as Figure 11 As shown, the first clamping assembly 71 includes three mutually parallel clamping arms 702, and each clamping arm 702 includes 3 clamping contact ends. The adjacent clamping arms 702 are connected together by a connecting sleeve 7021 to improve the rigidity strength.

[0081] It also includes a locking mechanism 703, and the locking mechanism 703 is used to fix the bottom plate clamping assembly in the clamping position.

[0082] The operating sequence of the tooling:

[0083] First, operate the flipping device 3 to make the substrate 2 in the Figure 3 shown front position, and then flip open and retract all the clamping mechanisms to the initial position.

[0084] First, place the outer scraping partition welding one 91 on the tooling. Use the first plane 121 and the second plane 122 in the first positioning component 400, the fourth plane 124 and the fifth plane 125 of the second positioning component 401 to support the first surface 101 of the outer scraping partition welding one 91, limit the up and down positions, use the first vertical surface 131 and the second vertical surface 132 in the first positioning component 400 to limit and fix the second surface 102 and the third surface 103 of the outer scraping partition welding one 91, and use the first side surface 141, the second side surface 142, and the third side surface 143 of the second positioning component 401 to abut against the hollow part of the outer scraping partition welding one 91 and the side wall of the hollow part of the vertical plate to fix the fifth surface 105, the sixth surface 106, the eighth surface 108, and the ninth surface 109 of the outer scraping partition welding one 91. Use the first positioning groove 151, the second positioning groove 152, and the third positioning groove 153 of the third positioning component 402 to fix the up and down positions and the left and right positions of the three vertical plates where the sixteenth surface 116, the seventeenth surface 117, and the eighteenth surface 118 of the outer scraping partition welding one 91 are located.

[0085] Then, place the outer scraping partition welding two 92 on the tooling. Use the third plane 123 of the first positioning component 400, the fourth plane 124, and the sixth plane 126 of the second positioning component 401 to support the tenth surface 110 of the outer scraping partition welding two 92. Use the third vertical surface 133 of the first positioning component 400 to fix the fourth surface 104 of the outer scraping partition welding two 92. Use the second side surface 142 and the third side surface 143 of the second positioning component 401 to fix the thirteenth surface 113 and the eleventh surface 111 of the outer scraping partition welding two 92. Use the fourth positioning groove 154 of the third positioning component 402 to fix the up and down and left and right positions of the edge vertical plate where the nineteenth surface 119 of the outer scraping partition welding two 92 is shown, and use the detection pin body 502 to detect whether it is installed in place.

[0086] Then, the outer scraper mounting plate 93 is placed on the tooling, and the 14th surface of the outer scraper mounting plate 93 is fixed by the seventh plane 127, the eighth plane 128, and the ninth plane 129 of the suspended plate positioning clamp 403, and the two holes of the outer scraper mounting plate 93 are fixed by the top screw of the suspended plate positioning clamp 403 to tighten the diamond positioning pin 4035 and the top screw to tighten the cylindrical positioning pin 4036. The magnet 4037 adsorbs the outer scraper mounting plate 93, so it is not necessary to lift the outer scraper mounting plate 93 by manpower during assembly, and then the outer scraper mounting plate 93 is clamped by two C-type clamps 72. Then, the push-pull clamp 4032 is started to push the outer scraper mounting plate 93 to the required position.

[0087] Then rotate the first clamping assembly 71 around the pin shaft, and the small plane below the clamping arm 702 is pressed against the opposite side of the first side 101 of the outer scraper baffle weld 91 and the opposite side of the tenth side 110 of the outer scraper baffle weld 92. If necessary, a pad 7022 can be added to avoid damage to the outer surface of the workpiece. Then use the two clamping arms 702 of the third clamping assembly 73 to rotate around the pin shaft, and then put on the strap 7031. Tighten the clamping bolt 9 through the handle 7033, so that the clamping block 7032 presses the upper plate 7034 of the first clamping assembly 71 into the groove above the two guide plates 701, thereby achieving the clamping of the outer scraper baffle weld 91 and the outer scraper baffle weld 92.

[0088] At this time, all welds that can be welded on this surface are welded.

[0089] Then hold the first reinforcing connecting plate 95, the second reinforcing connecting plate 96, and the third reinforcing connecting plate 97, and place them in the positions shown in the figure for welding (these three parts do not need to be positioned).

[0090] Because both the left and right parts are positioned, clamped and welded on this set of tooling, the tooling is made universal.

[0091] Then operate the flipping device 3 to flip the substrate 2 180 degrees, and complete all the welds that can be welded on the reverse side through the hollow area 201. Then operate the flipping device 3 again to put the substrate 2 in a Figure 3 The front position shown in the figure is then opened or withdrawn from all positioning and clamping devices, and the two welded parts are removed from the tooling. Then the outer scraping guide plate 98 is held in the position shown in the figure (this part does not need to be positioned) and welded. At this point, the process is completely over.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
