[0002] The elbow of the grain unloading cylinder is one of the key components of the grain unloading system of the harvester, and is used to change the flow direction of the grain conveyed from the inside of the harvester and guide it to a specified position at a suitable angle. Therefore, the processing quality of the elbow of the grain unloading cylinder directly affects the grain unloading efficiency and reliability of the harvester.

[0003] During the processing of the elbow of the grain unloading cylinder, it is necessary to use a milling cutter to mill the elbow of the unloading cylinder on a machining center, which requires the use of clamping tooling to clamp and fix the elbow of the unloading cylinder. Due to the complex shape of the elbow of the unloading cylinder, the standard elbow clamping tooling cannot perform stable clamping. Therefore, it is necessary to design a clamping tooling suitable for the processing of the elbow of the grain unloading cylinder. Summary of the Utility Model

Detailed Description of the Preferred Embodiment

[0025] As Figure 1-2 shown, a clamping tooling suitable for the processing of the elbow of a grain unloading cylinder includes a tooling platform 1. On the top of the tooling platform 1, there are a first support plate 2 and a second support plate 3 for respectively supporting and limiting the two ends of the elbow of the unloading cylinder. The distribution directions of the first support plate 2 and the second support plate 3 are perpendicular to each other. On the tooling platform 1, there is also a third support plate 4 for supporting and limiting the shaft cylinder on the elbow of the grain unloading cylinder. On the tooling platform 1, fourth support plates 5 are arranged near both ends of the corresponding rectangular steps on the elbow of the grain unloading cylinder. On the tooling platform 1, two pressing assemblies 6 are arranged symmetrically and obliquely on both sides of the unloading cylinder elbow.

[0026] With such a design, firstly, the two ends of the elbow of the grain unloading cylinder are respectively supported and limited by the first support plate 2 and the second support plate 3, and the distribution directions are perpendicular to each other, which can stably support the elbow from two different directions and ensure that the elbow will not be displaced or shaken during the processing.

[0027] Secondly, the shaft cylinder of the elbow of the grain unloading cylinder is supported and limited by the third support plate 4, and the rectangular steps on the elbow of the grain unloading cylinder are supported and limited by the fourth support plate 5, providing additional support points for the entire grain unloading cylinder structure, enhancing its stability on the tooling, thereby helping to withstand various forces and vibrations during the processing and reducing the processing errors and scrap rates caused by unstable structures.

[0028] Furthermore, the two pressing assemblies 6 are symmetrically and obliquely arranged on both sides of the unloading cylinder elbow, which can apply uniform pressure to the elbow from different angles, ensuring that the elbow always maintains a stable clamping state during the processing and effectively avoiding deformation or displacement of the elbow caused by excessive unilateral force.

[0029] The first support plate 2 and the second support plate 3 are respectively provided with a first arc groove and a second arc groove, and the first arc groove and the second arc groove are respectively adapted to the outer side walls of the elbow of the unloading cylinder.

[0030] With such a design, first of all, both the first arc-shaped groove and the second arc-shaped groove are adapted to the outer wall of the discharge barrel elbow. The tight fit can achieve precise positioning, prevent the transverse and longitudinal displacement of the discharge barrel elbow during processing, and ensure the accuracy of processing. At the same time, the fit increases the contact area, improves the support stability, firmly fixes the discharge barrel elbow, and prevents it from shaking and tilting during processing, which is conducive to ensuring the processing quality.

[0031] Secondly, the design of the first arc-shaped groove and the second arc-shaped groove can evenly distribute the processing force on the surface of the discharge barrel elbow, so that it can better withstand forces in different directions, reduce local stress concentration, and lower the risk of deformation and damage. Moreover, the smooth surface of the arc-shaped groove can reduce the wear and scratch on the outer wall of the discharge barrel elbow, improving the service life and appearance quality of the discharge barrel elbow.

[0032] Finally, the fact that both the first arc-shaped groove and the second arc-shaped groove are adapted to the discharge barrel elbow enables quick and accurate placement during installation, without the need for complex adjustment and alignment, saving installation time and improving processing efficiency.

[0033] A third arc-shaped groove is provided on the third support plate 4, and the third arc-shaped groove is adapted to the outer wall of the shaft barrel of the grain unloading barrel elbow.

[0034] With such a design, first of all, the third arc-shaped groove is adapted to the outer wall of the shaft barrel of the grain unloading barrel elbow. The tight fit can achieve precise positioning and ensure the accuracy of processing. At the same time, the fit increases the contact area, improves the support stability, firmly fixes the discharge barrel elbow, and prevents it from shaking and tilting during processing, which is conducive to ensuring the processing quality.

[0035] Secondly, the design of the third arc-shaped groove can evenly distribute the processing force on the surface of the shaft barrel of the grain unloading barrel elbow, so that it can better withstand forces in different directions, reduce local stress concentration, and lower the risk of deformation and damage. Moreover, the smooth surface of the third arc-shaped groove can reduce the wear and scratch on the outer wall of the shaft barrel surface of the grain unloading barrel elbow, improving the service life and appearance quality of the shaft barrel surface of the grain unloading barrel elbow.

[0036] Finally, the adaptation of the third arc-shaped groove to the shaft barrel of the discharge barrel elbow enables quick and accurate placement during installation, without the need for complex adjustment and alignment, saving installation time and improving processing efficiency.

[0037] The top of the fourth support plate 5 is of an "L"-shaped step structure and its step plane is horizontal. The top of the fourth support plate 5 is in close contact with the rectangular step on the outer wall of the discharge barrel elbow.

[0038] With such a design, firstly, it provides stable support for the discharge barrel, making it not easy to shake or shift during operation. Secondly, it evenly distributes the weight of the discharge barrel, reduces local stress concentration, and extends the service life. Thirdly, during installation, only alignment and fitting are required, enabling quick and accurate placement during installation, without the need for complex adjustment and alignment, saving installation time and improving processing efficiency.

[0039] The pressing assembly 6 includes a bearing plate 61 fixedly installed on the top of the tooling platform 1, and the bearing plate 61 is arranged perpendicular to the tooling platform 1.

[0040] A pressing plate 62 is movably arranged on the top of the bearing plate 61, and the bottom of the pressing plate 62 is flush with the top of the grain unloading pipe elbow.

[0041] With such a design, firstly, the vertically arranged bearing plate 61 and the tooling platform 1 form a stable right-angle structure, enabling the bearing plate 61 to better withstand the pressure from the pressing plate 62, ensuring that it will not deform or tilt during the process of pressing the grain unloading pipe elbow, thereby providing stable support for the entire pressing operation.

[0042] Secondly, the bottom of the pressing plate 62 is flush with the top of the grain unloading pipe elbow, so that when the pressing plate 62 presses the grain unloading pipe elbow, it can be closely attached to the grain unloading pipe elbow, ensuring uniform distribution of the pressing force, improving the pressing effect, and guaranteeing the stability and sealing performance of the grain unloading pipe elbow during operation.

[0043] Thirdly, this design allows the operator to intuitively see the relative position between the pressing plate 62 and the grain unloading pipe elbow, facilitating accurate adjustment of the position of the pressing plate 62, and making the operation process more convenient and efficient.

[0044] A baffle 63 is fixedly connected to the bottom of the end of the pressing plate 62 away from the grain unloading pipe elbow.

[0045] An activity groove 64 is formed through the top of the pressing plate 62, and the activity groove 64 is arranged along the length direction of the bearing plate 61.

[0046] The activity groove 64 is of a long strip structure, and both ends of the activity groove 64 are arc-shaped.

[0047] With such a design, stress concentration can be reduced, avoiding excessive stress at the corners that may cause cracks or damage to the bearing plate 61, making the stress distribution more uniform, and enhancing the overall strength and durability.

[0048] A threaded rod 65 is slidably inserted into the activity groove 64. The bottom end of the threaded rod 65 is fixedly connected to the tooling platform 1 by threading, and the top end of the threaded rod 65 passes through the activity groove 64 and is threadedly connected to a fastening nut 66.

[0049] During specific use, firstly, according to the actual situation of the grain unloading pipe elbow, the pressing plate 62 is pushed to move on the top of the bearing plate 61. At the same time, since the activity groove 64 is arranged along the length direction of the bearing plate 61 and the threaded rod 65 is slidably inserted into the activity groove 64, the threaded rod 65 slides in the activity groove 64 of the pressing plate 62, so that the pressing plate 62 is adjusted to a suitable position to effectively press the grain unloading pipe elbow.

[0050] When the clamping plate 62 is adjusted to a suitable position, tighten the fastening nut 66, which rotates downward on the threaded rod 65. The clamping plate 62 is firmly fixed at the current position through the squeezing effect with the supporting plate 61. At this time, the clamping plate 62 plays a role in limiting the movement of the elbow of the grain unloading drum.

[0051] With this design, firstly, the position can be easily adjusted by pushing the clamping plate 62 to move, which is simple and convenient and does not require complicated tools and skills, thus greatly saving time and labor costs.

[0052] Secondly, the clamping plate 62 can be firmly fixed by tightening the clamping nut 66, effectively preventing the grain unloading drum elbow from loosening or shifting due to various external forces, and effectively ensuring the stability and safety of the work.

[0053] Thirdly, the convenient operation and reliable fixing method greatly reduce the time required for equipment installation and commissioning, thereby greatly improving the efficiency of the entire workflow and making the entire work process smoother and more efficient.

[0054] The first support plate 2 , the second support plate 3 , the third support plate 4 and the fourth support plate 5 are all arranged perpendicular to the tooling platform 1 .

[0055] With this design, each support plate is vertically arranged with the tooling platform 1 to form a stable right-angle structure, which not only enables the support plate to better withstand pressure and various forces, ensuring that the device does not tilt or shake; it also achieves uniform force, evenly transferring the force to the tooling platform 1, reducing local stress concentration and extending the life of the equipment; it is also easy to install and adjust, without the need for complex angle adjustments during installation, and it is also easier to measure and position during adjustment, thereby improving efficiency.

[0056] The four corners of the tooling platform 1 are penetrated by connection holes 7 .

[0057] In this design, the connection holes 7 are arranged at the four corners of the tooling platform 1, so that the tooling platform can be conveniently fixed at a desired position by connecting members such as bolts and screws.

[0058] The bottom of the tooling platform 1 is evenly provided with a plurality of convex grooves 8 along its length direction, and the convex grooves 8 extend along its width direction.

[0059] With this design, firstly, the design of the convex groove 8 increases the contact area between the bottom of the tooling platform 1 and the external support structure or the installation foundation, so that the tooling platform 1 can more evenly distribute the pressure when bearing weight and external force, thereby improving the stability of the support.

[0060] Secondly, the shape of the convex groove 8 has a certain guiding effect, enabling the tooling platform 1 to be more easily aligned and positioned with the external support structure or installation foundation during the installation process. This guiding effect can reduce errors during the installation process and improve the installation accuracy and efficiency.

[0061] For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principles and spirit of the present utility model, changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present utility model.
