Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery parts grinding technology, and in particular to an agricultural machinery parts processing and grinding device. Background Technology

[0002] In the manufacturing process of agricultural machinery parts, grinding is a crucial surface treatment step, especially for core shaft components such as drive shafts and output shafts. The grinding process directly affects the assembly accuracy and operational stability of the entire agricultural machinery. The key grinding areas for these shaft components are concentrated at the journal. Grinding effectively removes residual burrs, oxide scale, and cutting marks from machining, precisely controlling surface roughness and ensuring that the fit clearance between the journal and the bearing inner ring strictly meets design requirements during use.

[0003] In related technologies, when using grinding devices to grind shafts such as drive shafts and output shafts, the journal surface needs to be ground to ensure the fitting accuracy with the bearing. However, existing grinding devices have insufficient adaptability when grinding these shaft parts. For example, for shaft parts of different diameters, existing grinding devices often cannot quickly adjust the height of the clamping components, resulting in inaccurate contact between the grinding wheel and the journal of the shaft part during the grinding process, which can easily lead to over-grinding or under-grinding. In addition, existing grinding devices require multiple manual adjustments and fixations when clamping shaft parts of different sizes, which increases the labor intensity of operators and reduces production efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a processing and grinding device for agricultural machinery parts. The device clamps and fixes shaft parts by means of a clamping plate, and adjusts the height of the shaft parts by rotating the adjusting screw. This achieves precise contact between the grinding wheel and the journal of the shaft parts, thereby significantly improving the adaptability to shaft parts of different sizes and the overall production efficiency.

[0006] To achieve the above objectives, this utility model proposes an agricultural machinery parts processing and grinding device, including a frame, a grinding motor, a grinding wheel, a drive assembly, and a parts mounting mechanism. The grinding motor is mounted on the frame, and its drive shaft is connected to the grinding wheel. The parts mounting mechanism is mounted on the drive assembly, which is also mounted on the frame and drives the parts mounting mechanism to move horizontally along the axial direction of the grinding wheel. The parts mounting mechanism includes a clamping assembly and a position adjustment assembly. The clamping assembly is rotatably mounted on the position adjustment assembly, and the position adjustment assembly drives the clamping assembly to rotate synchronously. The position adjustment assembly moves and adjusts along the height direction of the frame.

[0007] In addition, the agricultural machinery parts processing and grinding device proposed above according to this utility model may also have the following additional technical features: Specifically, the driving component includes a linear module, a guide rail, and a support platform. The support platform is slidably disposed on the guide rail, the support platform is connected to a slider on the linear module, and the linear module drives the support platform to slide horizontally along the guide rail.

[0008] Specifically, the clamping assembly includes two clamping plates, two sliding seats, a double-ended lead screw, a drive motor, and a mounting base. The two clamping plates are symmetrically arranged, and each of them is provided with a rubber anti-slip pad. The clamping plates are disposed on the sliding seats. The two sliding seats are symmetrically threaded onto the double-ended lead screw and symmetrically slidably disposed inside the mounting base. The drive motor is disposed on the mounting base, and its output shaft is connected to one end of the double-ended lead screw. The other end of the double-ended lead screw is rotatably disposed inside the mounting base.

[0009] Specifically, the position adjustment assembly includes a rotating shaft, a support base, a transmission motor, an adjusting screw, and a base. The rotating shaft is rotatably disposed within the support base, the transmission motor is disposed on the support base and its output shaft is connected to the rotating shaft, the adjusting screw is rotatably disposed within the base, the support base is slidably disposed within the base and threaded onto the adjusting screw.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention uses a drive motor to rotate a double-ended lead screw, bringing two clamping plates closer together to clamp shaft-type fittings. Then, rotating an adjusting screw adjusts the height of the support base, moving the fitting to a suitable height. A linear module then drives the carrier platform to slide along the guide rail, bringing the shaft-type fitting into contact with a high-speed rotating grinding wheel for grinding. Compared to existing technologies, this device can adaptively clamp fittings of different sizes. Furthermore, by adjusting the height of the clamping components according to the diameter of the shaft-type fitting, it ensures precise contact between the grinding wheel and the journal of the shaft-type fitting, significantly improving adaptability to shaft-type fittings of different sizes and overall production efficiency.

Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The following description, in conjunction with the accompanying drawings, describes the agricultural machinery parts processing and polishing device according to an embodiment of the present invention.

[0016] like Figures 1-4 As shown, an agricultural machinery parts processing and grinding device according to an embodiment of the present utility model includes a frame 1, a grinding motor 2, a grinding wheel 3, a drive assembly 4 and a parts mounting mechanism, wherein the grinding motor 2 is mounted on the frame 1 and its drive shaft is connected to the grinding wheel 3; It should be noted that the grinding motor 2 is mounted on the frame 1 via a mounting bracket. The mounting bracket and the frame 1 are connected by bolts, which can ensure the stability of the grinding motor 2 during operation and prevent displacement due to vibration, thus affecting the grinding accuracy. The grinding motor 2 drives the grinding wheel 3 to rotate at high speed, thereby grinding the shaft parts of the agricultural machinery.

[0017] The accessory mounting mechanism is mounted on the drive assembly 4, which is mounted on the frame 1 and drives the accessory mounting mechanism to move horizontally along the axis of the grinding wheel 3. It should be noted that the accessory installation mechanism is used to install and fix the shaft accessories of agricultural machinery. The drive component 4 drives the accessory installation mechanism to move axially in the grinding wheel 3, so that the shaft accessories can come into contact with the grinding wheel 3, thereby achieving the grinding of the accessories. Moreover, by driving the shaft accessories to move, it can adapt to shaft accessories of different lengths.

[0018] The accessory installation mechanism includes a clamping component 5 and a position adjustment component 6. The clamping component 5 is rotatably mounted on the position adjustment component 6, and the position adjustment component 6 drives the clamping component 5 to rotate synchronously. The position adjustment component 6 moves and adjusts along the height direction of the frame 1. It should be noted that the clamping component 5 is used to clamp and fix the shaft-type accessories to prevent them from sliding or falling off during the grinding process, thus ensuring the stability and safety of the grinding process; the position adjustment component 6 can realize the rotation adjustment of the clamping component 5 in the horizontal direction, thereby achieving complete grinding of the circumferential surface of the shaft journal of the shaft-type accessories. Adjusting component 6 can adjust the height of clamping component 5 to accommodate the grinding needs of shaft accessories of different diameters; Furthermore, by adjusting the height, it is possible to ensure precise contact between the grinding wheel 3 and the journal of the shaft accessory. Moreover, the position of the shaft accessory can be flexibly adjusted according to its specific size and grinding requirements, so that the shaft accessory is in the optimal grinding position. This enhances the adaptability of the grinding device to shaft accessories of different sizes, solves the problem of insufficient adaptability of existing grinding devices, and improves the flexibility of the entire agricultural machinery parts grinding production.

[0019] In one embodiment of this utility model, such as Figure 1 As shown, the drive assembly 4 includes a linear module 41, a guide rail 42, and a support platform 43. The support platform 43 is slidably disposed on the guide rail 42. The support platform 43 is connected to the slider on the linear module 41, and the linear module 41 drives the support platform 43 to slide horizontally along the guide rail 42. It should be noted that both the guide rail 42 and the linear module 41 are mounted on the frame 1. The bottom of the support platform 43 is provided with a matching slide. Through the cooperation between the slide and the guide rail 42, it can be ensured that the support platform 43 can slide horizontally along the guide rail 42. It is understandable that the linear module 41 drives the support platform 43 to slide along the guide rail 42, the support platform 43 drives the accessory installation mechanism, and the accessory installation mechanism drives the shaft accessories to move along the axial direction of the grinding wheel 3, thereby realizing the grinding operation of the shaft accessories.

[0020] In one embodiment of this utility model, such as Figure 2-3As shown, the clamping assembly 5 includes two clamping plates 52, two sliding seats 53, a double-ended lead screw 54, a drive motor 55, and a mounting base 56. The two clamping plates 52 are symmetrically arranged, and each of them is provided with a rubber anti-slip pad 51 inside. It should be noted that the clamping plate 52 is V-shaped, which can fit the shape of shaft-type accessories and increase the stability of clamping. When clamping shaft-type fittings, the rubber anti-slip pad 51 can increase the friction between the clamping plate 52 and the shaft-type fittings, preventing the fittings from sliding during the grinding process, and also preventing the clamping plate 52 from damaging the surface of the fittings. The clamping plate 52 is set on the sliding seat 53. The two sliding seats 53 are symmetrically threaded on the double-ended lead screw 54 and symmetrically slidably set inside the mounting seat 56. The drive motor 55 is set on the mounting seat 56, and its output shaft is connected to one end of the double-ended lead screw 54. The other end of the double-ended lead screw 54 is rotatably set inside the mounting seat 56. It should be noted that the mounting base 56 is provided with a sliding groove that matches the sliding seat 53, so that the sliding seat 53 can slide along the sliding groove and ensure the smoothness of the sliding process. The drive motor 55 is connected to the double-ended lead screw 54 via a coupling, which ensures the effectiveness of power transmission; the terminals of the drive motor 55 are connected to electric slip rings, which can prevent the wires from getting tangled when the clamping assembly 5 rotates. Understandably, when loading shaft-type accessories, the accessories are placed between two clamping plates 52. The drive motor 55 drives the double-ended lead screw 54 to rotate in the forward direction. The double-ended lead screw 54 drives the two sliding seats 53 through the threads on its surface, thereby bringing the sliding seats 53 closer together, which in turn drives the two clamping plates 52 to perform the clamping operation on the shaft-type accessories.

[0021] In one embodiment of this utility model, such as Figure 3-4 As shown, the position adjustment assembly 6 includes a rotating shaft 61, a support base 62, a drive motor 63, an adjusting screw 64, and a base 65. The rotating shaft 61 is rotatably mounted inside the support base 62, and the drive motor 63 is mounted on the support base 62, with its output shaft connected to the rotating shaft 61. It should be noted that the rotating shaft 61 is rotatably mounted in the support base 62 via a bearing, which ensures the smoothness of rotation.

[0022] The adjusting screw 64 is rotatably mounted inside the base 65, and the support seat 62 is slidably mounted inside the base 65 and threaded onto the adjusting screw 64. It should be noted that the base 65 is fixedly mounted on the support platform 43, and the base 65 is provided with a guide groove that matches the support 62. The support 62 is slidably connected to the base 65 through the guide groove, which can ensure that the support 62 moves stably up and down under the drive of the adjusting screw 64. A handwheel is provided at the top of the adjusting screw 64. By rotating the handwheel, the adjusting screw 64 can be rotated, which can adjust the height of the support base 62 and thus the height of the clamping assembly 5 to accommodate shaft accessories of different diameters.

[0023] Understandably, when grinding shaft-type fittings is required, the shaft-type fittings are first placed between two clamping plates 52. The drive motor 55 drives the double-ended lead screw 54 to rotate, bringing the two clamping plates 52 closer together to clamp the shaft-type fittings. Then, according to the diameter of the shaft-type fittings, the height of the support base 62 is adjusted by rotating the adjusting screw 64, so that the fittings between the two clamping plates 52 are moved to a suitable height. Next, the linear module 41 drives the bearing platform 43 to slide along the guide rail 42, so that the shaft-type fittings come into contact with the high-speed rotating grinding wheel 3, and the grinding operation can then be performed. During the grinding process, the drive motor 63 drives the rotating shaft 61 to rotate, thereby driving the shaft-type parts to rotate, and the journal of the shaft-type fittings is ground from all directions.

[0024] In summary, the agricultural machinery parts processing and grinding device of this utility model uses a clamping assembly to clamp and fix shaft parts, ensuring the stability of the grinding process. By setting a position adjustment assembly, the height of the clamping assembly can be adjusted according to shaft parts of different diameters, ensuring precise contact between the grinding wheel and the journal of the shaft part. This significantly improves the adaptability to shaft parts of different sizes and the overall production efficiency. Then, by driving the clamping assembly and shaft parts to rotate through the transmission motor, all-round grinding of the journal of the shaft parts can be achieved, ensuring the grinding quality of the parts.
