Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to a riveting and welding positioning tooling for a sugarcane machine frame. Background Technology

[0002] A sugarcane harvester is a crop harvesting machine used to harvest sugarcane stalks. The frame of a sugarcane harvester mainly consists of welded front left and right side plates, an engine mounting bracket, a cab mounting seat, and welded rear left and right side plates. During the riveting and welding assembly and positioning of the workpieces, it is crucial to ensure the coaxiality of the front and rear left and right side plates, the positioning dimensions and flatness of the engine mounting bracket, the spacing dimensions and tolerances of the cab mounting seat, and the internal opening dimensions and tolerances of the side plate components.

[0003] The existing manufacturing method involves manually marking the position lines of each sub-welded component on a tooling platform, hoisting each sub-welded component to the tooling platform, using a right-angle ruler to ensure the verticality of the welded component, measuring the positioning dimensions of each sub-welded component with a tape measure, and then using process tie rods for welding and fixing. Finally, the connecting welds of each welded component are welded, and the workpiece is shaped after welding is completed.

[0004] The existing installation method uses manual marking for positioning, resulting in large deviations in the positioning dimensions of the workpiece, making it impossible to guarantee the positioning dimensions of each sub-welded component, and is also inefficient. The connection and fixation of each sub-welded component is done by welding with process tie rods, which leads to damage to the sub-welded components and requires subsequent grinding of the weld points on the welded components, resulting in low installation efficiency. There is no rigid fixation during the welding process, resulting in large welding deformation and causing the internal opening dimensions of the workpiece to exceed the design dimensional tolerances. Utility Model Content

[0005] The purpose of this utility model is to provide a riveting and welding positioning fixture for a sugarcane machine frame, which solves the problems of existing frame installation methods that rely on manual marking for positioning, resulting in large deviations in workpiece positioning dimensions, inability to guarantee the positioning dimensions of each sub-welded component, and low efficiency; the use of process tie rods to weld and fix each sub-welded component, leading to damage to the sub-welded component and subsequent grinding of the weld points, resulting in low installation efficiency; and the lack of rigid fixation during welding, leading to large welding deformation and causing the workpiece's internal opening dimensions to exceed design tolerances.

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] The following description, with reference to the accompanying drawings, describes a riveting and positioning fixture for a sugarcane machine frame according to the present invention.

[0032] See Figure 1 The sugarcane machine frame mentioned in this utility model includes a front left side plate 81, a front right side plate 82, a rear left side plate 83, a rear right side plate 84, an engine frame 85, and a cab frame 86, wherein the front left side plate 81 and the front right side plate 82 are along the front-rear direction of the tooling platform 1 (e.g., Figure 2 The front left side plate 81 and the front right side plate 82 are positioned in the direction shown in the diagram, and are located in front of the rear left side plate 83 and the rear right side plate 84. The front left side plate 81 and the front right side plate 82 are positioned along the left and right directions of the tooling platform 1 (as shown in the diagram). Figure 2 The rear left side plate 83 and the rear right side plate 84 are spaced apart along the left and right directions of the tooling platform 1 (as shown in the diagram). Figure 2The engine frame 85 is positioned above the rear of the front left side plate 81 and the front right side plate 82, and the cab frame 86 is positioned above the rear left side plate 83 and the rear right side plate 84.

[0033] See Figures 2 to 9 The riveting and positioning fixture for a sugarcane machine frame provided by this utility model includes a fixture platform 1, a front side plate positioning unit 2, a rear side plate positioning unit 3, an engine frame positioning unit 4, a cab frame positioning unit 5, multiple front side plate support mechanisms, and multiple rear side plate support mechanisms 7. The fixture platform 1 is used to place the sugarcane machine frame 8. The front side plate positioning unit 2 is installed on the front side of the fixture platform 1 and is used to fix the front side plate of the frame 8. The rear side plate positioning unit 3 is installed on the rear side of the fixture platform 1 and is used to fix the rear side plate of the frame 8. The engine frame positioning unit 4 is installed on... The tooling platform 1 is used to fix the engine frame 85 of the machine frame 8. The cab frame positioning unit 5 is installed on the tooling platform 1 and is used to fix the cab frame 86 of the machine frame 8. Multiple front side plate support mechanisms are used to support the front side plates in the vertical direction, and multiple rear side plate support mechanisms 7 are used to support the rear side plates in the vertical direction. Among them, the front side plate positioning unit 2, the rear side plate positioning unit 3, the engine frame positioning unit 4, and the cab frame positioning unit 5 are positioned according to the positions of the front side plates, rear side plates, engine frame 85, and cab frame 86 of the machine frame 8 along the front-rear direction of the tooling platform 1 (e.g., ...). Figure 2 The directions shown are spaced apart on the tooling platform 1.

[0034] The front side panel positioning unit 2, rear side panel positioning unit 3, engine frame positioning unit 4, and cab frame positioning unit 5 are positioned on the tooling platform 1 according to the positions of the front side panel, rear side panel, engine frame 85, and cab frame 86 of the frame 8. This allows for precise fixing of the front side panel, rear side panel, engine frame 85, and cab frame 86 of the frame 8, reducing dimensional deviations of the components on the frame 8, ensuring that the inner opening dimensions of the workpiece are within the design dimensional tolerance range, and improving the positioning and installation efficiency of each component. The front side panel positioning unit 2 and rear side panel positioning unit 5 further enhance the positioning efficiency. 3. The engine frame positioning unit 4 and the cab frame positioning unit 5 fix the front side plate, the rear side plate, the engine frame 85, and the cab frame 86 respectively. There is no need to weld and fix the components of the frame 8 by means of process tie rods. This can avoid damage to the components of the frame 8 and improve the installation efficiency of the frame 8. At the same time, it can effectively reduce the deformation of the frame 8 during the welding process. The front side plate support mechanism and the rear side plate support mechanism 7 can effectively support the front side plate and the rear side plate in the vertical direction, ensuring that the front side plate and the rear side plate are accurately placed at the corresponding height on the tooling platform 1, thereby improving the installation accuracy of the frame 8.

[0035] In some embodiments, the tooling platform 1 is drilled by a CNC machine tool according to the position of each component of the frame 8 to ensure the installation position of each positioning component. The front side plate positioning unit 2, the rear side plate positioning unit 3, the engine frame positioning unit 4, the cab frame positioning unit 5, multiple front side plate support mechanisms and multiple rear side plate support mechanisms 7 are detachably installed on the tooling platform 1 by bolts or pins.

[0036] In some embodiments, the front side plate support mechanism and the rear side plate support mechanism 7 are structured as a sleeve disposed on the tooling platform 1 and a rod disposed in the sleeve in a vertical direction.

[0037] In some embodiments, the sleeve has an internal threaded hole, and the outer wall of the sleeve rod has an external thread that engages with the internal threaded hole.

[0038] In some embodiments, the heights of the front side panel support mechanism and the rear side panel support mechanism 7 are adjustable to adjust the heights of the front side panel and the rear side panel.

[0039] See Figure 4 In some embodiments, the front side plate positioning unit 2 is used to fix the front side plate along the front-rear direction of the tooling platform 1 (e.g., Figure 2 The position (as shown in the direction), along the left and right directions of tooling platform 1 (such as...) Figure 2 The direction shown defines the inward opening size between the front left side plate 81 and the front right side plate 82 of the front side panel and is along the left-right direction of the tooling platform 1 (as shown in the figure). Figure 2 (As shown in the direction) clamps the front left side plate 81 and the front right side plate 82. The front side plate positioning unit 2, by limiting the inward opening size of the front left side plate 81 and the front right side plate 82, can ensure the positioning size of the front left side plate 81 and the front right side plate 82. By fixing the front and rear positions of the front left side plate 81 and the front right side plate 82 and clamping them in the left and right directions, it can ensure the stability of the front left side plate 81 and the front right side plate 82 in the horizontal direction and avoid the displacement of the front left side plate 81 and the front right side plate 82 in the installation process.

[0040] In some embodiments, the front side plate positioning unit 2 includes a front side plate center positioning component and a first front side plate center clamping component 26. The front side plate center positioning component is used to fix the position of the front side plate in the front-rear direction of the tooling platform 1. The first front side plate center clamping component 26 is used to limit the inward opening size between the upper parts of the middle of the front left side plate 81 and the front right side plate 82 and clamp the upper parts of the middle of the front left side plate 81 and the front right side plate 82 in the left-right direction of the tooling platform 1. After the first front side plate center clamping component 26 limits the inward opening size of the upper parts of the front left side plate 81 and the front right side plate 82, the front side plate center positioning component can fix the position of the front left side plate 81 and the front right side plate 82 in the front-rear direction of the tooling platform 1, and the first front side plate center clamping component 26 can fix the position of the front left side plate 81 and the front right side plate 82 in the left-right direction of the tooling platform 1, ensuring the accuracy and stability of the relative position of the front left side plate 81 and the front right side plate 82 on the tooling platform 1.

[0041] In some embodiments, the front side plate positioning unit 2 further includes a second front side plate mid-section clamping assembly 27. The second front side plate mid-section clamping assembly 27 is used to define the inward opening size between the lower portions of the middle of the front left side plate 81 and the front right side plate 82, and to clamp the lower portions of the middle of the front left side plate 81 and the front right side plate 82 in the left-right direction along the tooling platform 1. The provision of the second front side plate mid-section clamping assembly 27 can further improve the inward opening size of the middle of the front left side plate 81 and the front right side plate 82, and at the same time clamp the middle of the front left side plate 81 and the front right side plate 82, so as to further improve the accuracy and stability of the relative position of the front left side plate 81 and the front right side plate 82 on the tooling platform 1.

[0042] See Figure 4 In some embodiments, the front side panel positioning unit 2 includes at least three first positioning posts 20, which are vertically arranged on the top surface of the tooling platform 1 and include a first left positioning post, a first middle positioning post, and a first right positioning post spaced apart along the left and right directions of the tooling platform 1; the front side panel middle positioning assembly includes a first positioning shaft 21, which is movably arranged on the at least three first positioning posts 20 and is used to pass through the middle of the front left side panel 81 and the front right side panel 82 along the left and right directions of the tooling platform 1 to fix the position of the front left side panel 81 and the front right side panel 82 along the front and rear directions of the tooling platform 1. The front left side plate 81 is hoisted between the first left positioning post and the first middle positioning post, and the front right side plate 82 is hoisted between the first right positioning post and the first middle positioning post. The first positioning shaft 21 is passed through the first left positioning post, the positioning hole in the middle of the front left side plate 81, the first middle positioning post, the positioning hole in the middle of the front right side plate 82, and the first right positioning post in sequence, so as to fix the positions of the front left side plate 81 and the front right side plate 82 in the front-back direction of the tooling platform 1, and prevent the front left side plate 81 and the front right side plate 82 from moving in the front-back direction of the tooling platform 1 during the installation process.

[0043] In some embodiments, a first positioning block 22 is fixedly provided on the rear side of the first left positioning post, the first middle positioning post and the first right positioning post. Multiple first positioning blocks 22 are provided with first positioning holes along the left and right directions of the tooling platform 1. The first positioning shaft 21 can pass through multiple first positioning holes in sequence to be installed on the first left positioning post, the first middle positioning post and the first right positioning post.

[0044] See Figure 4 In some embodiments, the first front side plate middle clamping assembly 26 includes at least two inner support members 271 and at least two abutting members 272. The two inner support members 271 are respectively disposed on the left and right side walls of the first middle positioning post along the left and right directions of the tooling platform 1. The distance between the two inner support members 271 is the same as the inward opening size between the upper part of the middle of the front left side plate 81 and the front right side plate 82. The two inner support members 271 are used to abut against the inner side of the front left side plate 81 and the front right side plate 82 respectively. The two abutting members 272 are respectively disposed on the right side wall of the first left positioning post and the left side wall of the first right positioning post along the left and right directions of the tooling platform 1, and are used to abut against the outer side of the front left side plate 81 and the front right side plate 82 respectively to abut against the two inner support members 271 respectively. The first front side plate middle clamping assembly 26 can effectively clamp the upper part of the middle of the front left side plate 81 and the front right side plate 82. The distance between the two inner support members 271 set in the first middle positioning post is the same as the inner opening size of the upper part of the front left side plate 81 and the front right side plate 82. The two inner support members 271 abut against the inner side of the front left side plate 81 and the front right side plate 82 respectively, thereby reducing the deviation of the inner opening size of the front left side plate 81 and the front right side plate 82. After the position of the front left side plate 81 and the front right side plate 82 along the front-back direction of the tooling platform 1 and the inner opening size are fixed, the abutting member 272 abuts the front left side plate 81 and the front right side plate 82 against the two inner support members 271 respectively, thereby ensuring the stability of the position of the front left side plate 81 and the front right side plate 82 and preventing the front left side plate 81 and the front right side plate 82 from displacement.

[0045] In some embodiments, the inner support member 271 is rotatable relative to the first positioning post 20 to contact or move away from the inner side of the front left side plate 81 and the front right side plate 82. When the front left side plate 81 and the front right side plate 82 are hoisted between the first positioning post 20, the inner support member 271 can ensure the inner opening size of the front left side plate 81 and the front right side plate 82 by contacting the front left side plate 81 and the front right side plate 82; when the frame 8 is riveted, the inner support member 271 is rotated relative to the first positioning post 20, so that the inner support member 271 moves away from the front left side plate 81 and the front right side plate 82, so as to facilitate the vertical movement of the front left side plate 81 and the front right side plate 82 of the frame 8 and improve the handling efficiency of the frame 8.

[0046] In some embodiments, the inner support member 271 includes a fixed seat 2712 fixedly disposed on the first positioning post, a rotating block 2713 rotatably disposed on the fixed seat 2712 via a connecting rod 2715, and a fixing pin 2714 fixing the rotating block 2713 to the fixed seat 2712. Pulling the fixing pin 2714 out of the rotating block 2713 and the fixed seat 2712 allows the rotating block 2713 to rotate relative to the fixed seat 2712, thereby moving the inner support member 271 away from the front left side plate 81 or the front right side plate 82; inserting the fixing pin 2714 into the rotating block 2713 and the fixed seat 2712 fixes the rotating block 2713 to the fixed seat 2712, thus fixing the inner support member 271 to the front left side plate 81 or the front right side plate 82.

[0047] In some embodiments, the clamping member 272 includes a fixed rod 2721 fixedly disposed on the first left positioning post and the first right positioning post, and a rotating rod 2722 rotatably disposed on the fixed rod 2721, the rotating rod 2722 extending in the left-right direction along the tooling platform 1. By rotating the rotating rod 2722, the rotating rod 2722 is brought closer to or away from the inner support member 271, thereby achieving the clamping or repositioning of the front left side plate 81 and the front right side plate 82 against or away from the inner support member 271.

[0048] In some embodiments, the outer wall of the rotating rod 2722 is provided with external threads, and the fixed rod 2721 is provided with an internal thread hole that mates with the external threads.

[0049] In some embodiments, a rotating seat is provided at one end of the rotating rod 2722 near the inner support member 271, and the rotating seat can abut against the front left side plate 81 or the front right side plate 82; a rotating handle is provided at the other end of the rotating rod 2722 away from the inner support member 271 to control the rotation of the rotating rod 2722.

[0050] It should be noted that any structure that can abut the front left side plate 81 or the front right side plate 82 against the inner support member 271 is within the protection scope of this utility model, and is not limited to the structure of the abutment member 272 mentioned in this utility model.

[0051] It is understandable that the clamping element 272 can also be a pneumatic clamping assembly or a hydraulic clamping assembly.

[0052] In some embodiments, the second front side plate middle clamping assembly 27 includes at least two inner support members 271 and at least two abutting members 272. The two inner support members 271 are disposed on the tooling platform 1 and are used to abut against the inner side of the lower part of the middle of the front left side plate 81 and the front right side plate 82, respectively. The distance between the two inner support members 271 is the same as the inner opening size between the lower part of the middle of the front left side plate 81 and the front right side plate 82. The two abutting members 272 are disposed at the lower part of the first left positioning post and the first right positioning post, respectively, and are used to abut against the outer side of the lower part of the middle of the front left side plate 81 and the front right side plate 82, respectively, to abut against the two inner support members 271.
