Description

Technical Field

[0001] This application relates to the field of agricultural machinery manufacturing technology, and in particular to a welding fixture for baler frame assembly. Background Technology

[0002] A baler is a machine used to bale straw, hay, and other raw materials into fixed-shape bales. Balers can pick up, bale, and unbale straw or hay such as rice straw, wheat straw, cotton stalks, corn stalks, rapeseed stalks, peanut vines, bean stalks, alfalfa, and flax. They are characterized by their simple and reasonable structure, durability, high efficiency, and ease of operation. When using a baler, machine parameters can be adjusted according to different raw materials and operational needs, such as adjusting bale density and compression force, to ensure operational efficiency and machine lifespan. In the baler's structure, the frame is the main structural component, and all linkage mechanisms are mounted on the frame. Because the frame is welded from multiple irregularly shaped thin plates, the machining accuracy of the frame directly affects the installation of subsequent components.

[0003] In related technical solutions, one method for manufacturing baler frames is manual welding. Specifically, this involves welding the pre-machined mounting holes of each frame component sequentially to form the baler frame. However, manual welding is inefficient, prone to errors, and results in poor manufacturing precision.

[0004] Another method for manufacturing baler frames is machining. This involves first welding the thin-plate components that make up the frame together, then placing the welded frame in a CNC machine tool. The CNC machine tool then machines the holes and mounting surfaces on the thin-plate components, ensuring precise relative positioning. However, since the frame is primarily constructed from welded thin plates, clamping it in the CNC machine tool is difficult. Furthermore, the frame needs to be flipped during machining, which can easily lead to deformation, making it difficult to guarantee machining accuracy and resulting in higher manufacturing costs. Summary of the Invention

[0005] In order to overcome the above-mentioned defects in related technologies, the purpose of this application is to provide a baler frame welding fixture. This application can position each frame part with pre-machined mounting holes, ensuring the coaxiality and other key dimensions of the mounting holes during part assembly welding, which helps to reduce the probability of frame deformation, improve processing efficiency and processing accuracy, and reduce processing costs.

[0045] As described in the background section, both processing methods for the baler frame in the related technologies have problems to varying degrees, resulting in poor precision of the processed frame.

[0046] In view of this, the present application aims to provide a welding fixture for assembling a baling machine frame. This fixture uses a main support frame and an adjustable support frame on a welding platform to position the main body and the base plate respectively. Specifically, the crossbeam positioning seat on the main support frame positions the coaxiality of the first and second crossbeams, and the two opposing side plate positioning seats position the coaxiality of the mounting holes on the first and second side plates.

Using this welding fixture, the frame parts with pre-machined mounting holes can be positioned, ensuring key dimensions such as the coaxiality of the mounting holes during component assembly. This helps reduce the probability of frame deformation, improves processing efficiency and accuracy, and reduces processing costs.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions that are perpendicular to each other in three-dimensional space.

[0049] Please refer to Figures 1-2This embodiment provides a welding fixture for assembling a baler frame, used to position the frame 1000 of the baler. The frame 1000 includes a main body portion 1100 and a base plate portion 1200 arranged along a first direction X. The main body portion 1100 and the base plate portion 1200 can be connected by a combination of various connection methods such as welding, riveting, and bolting. The main body portion 1100 includes a first crossbeam 1110, a second crossbeam 1120, a first side plate 1130, and a second side plate 1140. The first side plate 1130 is connected to the first crossbeam 1110, and the second side plate 1140 is connected to the second crossbeam 1120. Both the first side plate 1130 and the second side plate 1140 are irregularly shaped thin plate structures.

[0050] Please continue to refer to Figure 2 The welding fixture in this embodiment includes:

[0051] The riveting and welding platform 100 is provided with multiple fixing slots 110. In this embodiment, the riveting and welding platform is integrally cast from cast iron and then machined. The fixing slots 110 can be, for example, T-slots. The fixing slots 110 extend along the first direction X, and the multiple fixing slots 110 are spaced apart along the second direction Y.

[0052] The main support frame 200 is detachably connected to the fixing groove 110. For example, multiple mounting plates can be provided below the main support frame 200, and the mounting plates can be provided with portal holes. The mounting plates can be fixedly connected to the fixing groove 110 by fastening bolts and other parts. In this embodiment, the main support frame 200 includes a crossbeam positioning seat and at least two side plate positioning seats 220. Along the second direction Y, the two side plate positioning seats 220 are arranged relatively spaced apart, and the crossbeam positioning seat is disposed between the two side plate positioning seats 220. The crossbeam positioning seat is used to connect the first crossbeam 1110 and the second crossbeam 1120, thereby ensuring the coaxiality of the first crossbeam 1110 and the second crossbeam 1120, and ensuring that the first crossbeam 1110 and the second crossbeam 1120 are symmetrical with respect to the center of the frame in the second direction Y. The two side plate positioning seats 220 are respectively used to pass through the mounting holes on the first side plate 1130 and the second side plate 1140; the two side plate positioning seats 220 are used to position the coaxiality of the mounting holes on the first side plate 1130 and the second side plate 1140, thereby ensuring that the two sides of the main body of the frame are symmetrical with respect to the center of the frame.

[0053] An adjustable support frame 300 is detachably connected to a fixing groove 110. For example, multiple mounting plates can be provided below the adjustable support frame 300, and the mounting plates can be provided with door-shaped holes. The mounting plates can be fixedly connected to the fixing groove 110 by fastening bolts and other parts. In this embodiment, the adjustable support frame 300 abuts against the base plate portion 1200, and the position of the base plate portion 1200 can be adjusted along the third direction Z, so that the base plate portion 1200 and the main body portion 1100 correspond to each other in the third direction Z. The base plate portion 1200 can be positioned in the first direction X and the second direction Y by relying on the main body portion 1100 positioned by the main body support frame 200.

[0054] As described above, in this embodiment, the first crossbeam 1110 and the second crossbeam 1120 are connected by the crossbeam positioning seat of the main support frame 200 to ensure the coaxiality of the first crossbeam 1110 and the second crossbeam 1120; the coaxiality of the mounting holes on the first side plate 1130 and the second side plate 1140 is positioned by the two oppositely arranged side plate positioning seats 220, thereby ensuring that the two sides of the main frame part 1100 are symmetrical with respect to the frame center; the height of the bottom plate part 1200 is positioned by the adjustable support frame 300 to ensure the welding accuracy between the bottom plate part 1200 and the main frame part 1100. Using the welding fixture of this embodiment, the frame parts with the machined mounting holes can be positioned to ensure the coaxiality and other key dimensions of the mounting hole positions during the assembly welding of the parts, which helps to reduce the probability of deformation of the frame 1000, improve processing efficiency and processing accuracy, and reduce processing costs.

[0055] Please continue to refer to Figure 1 and Figure 3 In one possible implementation, the crossbeam positioning seat of this embodiment includes a first crossbeam positioning seat 211 and a second crossbeam positioning seat 212 arranged at intervals along a first direction X. The first crossbeam positioning seat 211 and the second crossbeam positioning seat 212 jointly position the first crossbeam 1110 and the second crossbeam 1120, ensuring that the first crossbeam 1110 and the second crossbeam 1120 are located at the center of the frame, and the relative positions of the first crossbeam 1110 and the second crossbeam 1120 with the hole system on the first side plate 1130 and the second side plate 1140.

[0056] Specifically, the first crossbeam positioning seat 211 includes a first crossbeam base 2111 and a first pin 2112. The first pin 2112 passes through the first crossbeam base 2111 along the second direction Y. The two ends of the first pin 2112 are used to connect the first crossbeam 1110 and the second crossbeam 1120, respectively. In use, the first pin 2112 can be inserted into the corresponding holes on the first crossbeam 1110 and the second crossbeam 1120, and then the first crossbeam 1110, the second crossbeam 1120 and the first crossbeam base 2111 can be locked and fixed using nuts and other parts.

[0057] The second crossbeam positioning seat 212 includes a second crossbeam seat body 2121 and a second pin 2122. Along the third direction Z, the length of the second crossbeam seat body 2121 is greater than the length of the first crossbeam seat body 2111, thereby positioning the higher parts of the first crossbeam 1110 and the second crossbeam 1120. The second crossbeam seat body 2121 is provided with a support plate 2123 arranged along the first direction X. The support plate 2123 is provided with a positioning groove 2124. The second pin 2122 passes through the positioning groove 2124 along the second direction Y. The two ends of the second pin 2122 are respectively used to connect the first crossbeam 1110 and the second crossbeam 1120. In use, the two ends of the second pin 2122 can be inserted into the corresponding holes on the first crossbeam 1110 and the second crossbeam 1120 respectively. Then, the second pin 2122, the first crossbeam 1110 and the second crossbeam 1120 are hoisted into the positioning groove 2124 as a whole to achieve the positioning of the first crossbeam 1110 and the second crossbeam 1120.

[0058] Furthermore, in this embodiment, the length of the positioning groove 2124 gradually increases in the direction away from the second crossbeam seat 2121 in the first direction X; that is, the positioning groove 2124 is larger near its opening, which facilitates the insertion of the second pin 2122 into the positioning groove 2124.

[0059] Please continue to refer to Figure 1 and Figure 2 In one possible implementation, the main support frame 200 of this embodiment further includes two lower rectangular tube positioning seats 230 arranged opposite each other along the second direction Y; along the first direction X, the lower rectangular tube positioning seats 230 are arranged close to the first crossbeam positioning seat 211. The lower rectangular tube positioning seats 230 are provided with lower rectangular tube positioning grooves 231, and the lower rectangular tube positioning grooves 231 on the two lower rectangular tube positioning seats 230 are respectively used to support the two ends of the lower rectangular tube. In use, the two ends of the lower rectangular tube can be respectively installed in the two lower rectangular tube positioning grooves 231, and the ear plates of the lower rectangular tube can be abutted against the inner sides of the opposite sides of the two lower rectangular tube positioning seats 230 to ensure that the lower rectangular tube assembly is located at the center of the frame and to ensure the relative position of the lower rectangular tube assembly with the holes on the first side plate 1130 and the second side plate 1140.

[0060] Please continue to refer to Figure 1 , Figure 2 and Figure 4 In one possible implementation, along the first direction X, the main support frame 200 is provided with a plurality of side plate positioning seats 220, which are evenly distributed on both sides of the main support frame 200 along the second direction Y and correspond one to one; the specific number of side plate positioning seats 220 can be determined according to the number of holes on the first side plate 1130 and the second side plate 1140.

[0061] Further, the side plate positioning seat 220 of this embodiment includes a side plate positioning seat body 221, a shaft head 222, a first pressure cover 223, a second pressure cover 224, and a fastener 225. The side plate positioning seat body 221 may be provided with weight-reducing holes to reduce the overall weight; the shaft head 222 is disposed on the side plate positioning seat body 221 along the second direction Y; the first side of the first pressure cover 223 is sleeved on the shaft head 222; the second side of the first pressure cover 223 has a protrusion 226, which is used to pass through the mounting holes on the first side plate 1130 or the second side plate 1140, thereby achieving positioning of the hole system on the first side plate 1130 and the second side plate 1140. The second pressure cover 224 is used to abut the first side plate 1130 or the second side plate 1140 against the second side of the first pressure cover 223, thereby clamping and fixing the first side plate 1130 or the second side plate 1140. Fastener 225 is used to fix the first cover 223 and the second cover 224 together. In this embodiment, the fastener 225 can be selected as a bolt, and the first cover 223 and the second cover 224 are provided with corresponding threaded holes. The bolt passes through the threaded holes to fix the first cover 223 and the second cover 224 relative to each other.

[0062] Furthermore, the protrusion 226 in this embodiment includes a first arcuate surface 2261, a second arcuate surface 2262, a first plane 2263, and a second plane 2264; wherein the first arcuate surface 2261 and the second arcuate surface 2262 are arranged opposite to each other along a first direction X, and the first plane 2263 and the second plane 2264 are arranged opposite to each other along a third direction Z; the two ends of the first plane 2263 and the two ends of the second plane 2264 are respectively connected to the first arcuate surface 2261 and the second arcuate surface 2262. With the above structure, this embodiment can reduce the manufacturing precision requirements of the protrusion 226, allowing for a larger allowance when the protrusion 226 mates with the mounting holes on the first side plate 1130 or the second side plate 1140.

[0063] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the main support frame 200 also includes a support platform 240, which is arranged along the third direction Z to provide a certain height for other parts on the main support frame 200. The support platform 240 is fixedly connected to the riveting and welding platform 100. In this embodiment, the support platform 240 is generally square, and the support platform 240 is connected to the mounting plate through multiple legs, and then fixed to the riveting and welding platform 100 through the mounting plate. The crossbeam positioning seat, the side plate positioning seat 220, and the lower rectangular tube positioning seat 230 are all fixed on the support platform 240. Optionally, the lower ends of the crossbeam positioning seat, the side plate positioning seat 220, and the lower rectangular tube positioning seat 230 can be provided with multiple through holes, and fixed connections with the support platform 240 can be achieved using bolts or other fasteners.

[0064] Please continue to refer to Figure 1 , Figure 2 and Figure 5 In one possible implementation, along the first direction X, the riveting platform 100 is provided with two sets of adjustable support frames 300. These two sets of adjustable support frames 300 are used to support and adjust both ends of the base plate portion 1200, thereby providing stable support. Specifically, the adjustable support frame 300 includes two support seats 310 arranged opposite each other along the second direction Y, and a support rod 320 connecting the two support seats 310. The support rod 320 is used to pass through the adjustment holes in the base plate portion 1200, and the support seats 310 can adjust the position of the support rod 320 in the third direction Z. In use, the base plate portion 1200 can be lifted using hoisting equipment, and then the support rod 320 can be passed through the corresponding holes in the base plate portion 1200 and installed on the two support seats 310. Finally, the support seats 310 can be used to adjust the position of the support rod 320 in the third direction Z, so that the base plate portion 1200 corresponds to the main body portion 1100, facilitating their assembly and connection.

[0065] Furthermore, the support base 310 in this embodiment includes a first support base body 311, a second support base body 312, a screw 313, and a nut 314. The first support base body 311 and the second support base body 312 are fixedly connected along the third direction Z, for example, by means of a flange connection; the screw 313 passes through the second support base body 312 and is fixedly connected to it; the nut 314 is disposed on the screw 313, and the end of the screw 313 facing away from the second support base body 312 is used to connect the support rod 320. In use, the nut abuts against the bottom of the support rod 320, and the position of the support rod 320 in the third direction Z is adjusted by rotating the nut.

[0066] When using the welding fixture of this embodiment, the two ends of the second pin 2122 can be inserted into the corresponding holes on the first crossbeam 1110 and the second crossbeam 1120 respectively. Then, the second pin 2122, the first crossbeam 1110 and the second crossbeam 1120 are hoisted into the positioning groove 2124 as a whole. The other hole on the first crossbeam 1110 and the second crossbeam 1120 is positioned by the first pin 2112.

[0067] After the first crossbeam 1110 and the second crossbeam 1120 are positioned, the lower rectangular tube assembly can be fixed using two lower rectangular tube positioning seats 230 to ensure that the lower rectangular tube assembly is located at the center of the frame and to ensure the relative position of the lower rectangular tube assembly with the holes on the first side plate 1130 and the second side plate 1140.

[0068] Then, the first side plate 1130 and the second side plate 1140 can be positioned using multiple side plate positioning seats 220, and the frame height and opening can be checked on the riveting and welding platform 100. The relative positions of the two side frames can be finely adjusted and checked to make the slides on the two side frames parallel and coplanar, which facilitates the welding of the first crossbeam 1110, the second crossbeam 1120, the lower rectangular tube assembly to the first side plate 1130 and the second side plate 1140.

[0069] Finally, the base plate 1200 is lifted using hoisting equipment, and the support rod 320 is inserted into the corresponding hole on the base plate 1200. The support rod 320 is then installed on two support seats 310. The support seats 310 can be used to adjust the position of the support rod 320 in the third direction Z, so that the base plate 1200 corresponds to the main body 1100, and the two are then welded and connected.

[0070] In this embodiment, the first crossbeam 1110 and the second crossbeam 1120 are connected by the crossbeam positioning seat of the main support frame 200 to ensure the coaxiality of the first crossbeam 1110 and the second crossbeam 1120; the coaxiality of the mounting holes on the first side plate 1130 and the second side plate 1140 is positioned by the two oppositely arranged side plate positioning seats 220, thereby ensuring that the two sides of the main body part 1100 of the frame are symmetrical with respect to the frame center; the height of the bottom plate part 1200 is positioned by the adjustable support frame 300 to ensure the welding accuracy between the bottom plate part 1200 and the main body part 1100. Using the welding fixture of this embodiment, the frame parts with the machined mounting holes can be positioned to ensure the coaxiality and other key dimensions of the mounting hole positions during the assembly welding of the parts, which helps to reduce the probability of deformation of the frame 1000, improve processing efficiency and processing accuracy, and reduce processing costs.
