Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an automotive parts grinding device. Background Technology

[0002] In the automotive manufacturing industry, the quality of components directly determines the safety, reliability, and driving performance of the entire vehicle. Automotive components include key parts such as engine blocks, shafts, transmission gears, wheel hubs, and chassis connectors. After being cast, forged, stamped, or welded, most components generally have defects such as burrs, oxide layers, weld slag, and flash on their surfaces. At the same time, due to the requirements of the processing technology, the surface roughness of some components cannot meet the assembly precision requirements. Therefore, they must undergo a grinding process to achieve surface refinement in order to ensure subsequent assembly precision and work requirements.

[0003] While existing grinding equipment can replace manual labor in grinding automotive parts, the loading, clamping, unloading, and disassembly of automotive parts still require manual operation. This is not only labor-intensive, but also poses a direct threat to the occupational health of operators due to the metal dust and noise generated during grinding. Furthermore, the low efficiency of manual loading and unloading means that grinding a single part often takes tens of minutes, which greatly limits the processing efficiency of the production line and cannot meet the pace of mass production of automotive parts. Therefore, an automotive parts grinding device is proposed. Summary of the Invention

[0038] To facilitate material supply and discharge, see attached Figure 6 As shown, a feeding trough 38 and a discharging trough 39 are provided on the side of the ring support 31. The feeding mechanism 4 and the unloading mechanism 5 are respectively installed in conjunction with the feeding trough 38 and the discharging trough 39. Specifically, the feeding trough 38 is fixedly installed in the middle of the front side of the ring support 31 for feeding short shaft workpieces. The feeding mechanism 4 is used for supplying and conveying short shaft workpieces. The feeding mechanism 4 includes a clamping conveyor belt 41, a supporting pulley 42, and a pulley drive motor 43, as shown in the attached figure. Figure 7As shown, the clamping conveyor belts 41 are arranged in pairs. Two sets of clamping conveyor belts 41 are symmetrically installed on the open sides of the feeding trough seat 38, supported by support pulleys 42 and driven by pulley drive motors 43. To improve driving stability, a second reducer is installed on the drive side of the pulley drive motor 43.

[0039] As attached Figure 6 As shown, the discharge trough seat 39 is fixedly installed at an incline on the outer edge of the ring support 31 for unloading and guiding the short shaft workpiece after processing. To facilitate the unloading and guiding of the short shaft workpiece, a discharge guide trough is provided in the middle of the discharge trough seat 39. The unloading mechanism 5 is used to assist in unloading and guiding the short shaft workpiece. The unloading mechanism 5 includes a support side seat 51, a push block drive cylinder 52, an unloading push block 53, and a sliding support block 54, as shown in the attached figure. Figure 8 As shown, the support side seat 51 is fixedly installed on the upper part of the processing table 1. The sliding block 54 is horizontally slidably installed on the lower part of the top seat of the support side seat 51 by means of a metal guide post. The push block drive cylinder 52 is a pneumatic cylinder. The push rod end of the push block drive cylinder 52 is fixedly installed on the middle part of the end side of the sliding block 54. The sliding block 54 is horizontally slidably installed on the upper part of the support side seat 51 by means of the push block drive cylinder 52.

The short-shaft workpiece is tilted laterally into the inner side of the discharge trough 39. The unloading push block 53 driven by the push block drive cylinder 52 pushes the processed short-shaft workpiece laterally. With the tilting and guiding of the discharge trough 39, the processed workpiece can be unloaded autonomously. The entire loading and unloading process is automatic. While reducing the consumption of processing manpower and the intensity of operation, it can greatly improve the production efficiency of the device. In order to realize the detection of the short-shaft workpiece on the discharge side and the rotation positioning and inspection of the work turntable 32, a photoelectric sensor is set in the middle of the support side seat 51.

[0040] Working principle or structural principle:

[0041] Workpiece loading: The short shaft workpieces in rows are placed into the feeding trough 38. Then, the two sets of clamping conveyor belts 41 are driven synchronously by the pulley drive motor 43. The short shaft workpieces are transported in a directional manner within the feeding trough 38 by the double-sided clamping of the two sets of clamping conveyor belts 41. After being transported in a directional manner by the clamping conveyor belts 41, the short shaft workpieces on the end side are fitted and supported by the positioning trough 36 that connects to the opening side of the feeding trough 38, thus completing the conveying and loading of the short shaft workpieces.

[0042] Workpiece turnover and grinding: After the workpiece is loaded, the turntable drive motor 33 drives the work turntable 32 to rotate at a fixed angle. During the process, the positioning slot 36 loaded with short shaft workpieces and the feeding slot 38 are separated alternately, and the short shaft workpieces are moved to the next station. At the same time, the clamping conveyor belt 41 loads the next set of short shaft workpieces into the next set of positioning slots 36. When the short shaft workpieces move to the grinding station, the limiting clamp 34 is driven to move inward by the clamping block drive cylinder 35 to clamp and support the short shaft workpieces in the positioning slot 36. Then, the servo module drives the grinding head 26 to move down to grind the end of the short shaft workpiece, completing the grinding process of the short shaft workpiece. After that, the grinding head 26 moves up to reset, and the limiting clamp 34 is driven to retract and reset by the clamping block drive cylinder 35, completing the turnover and grinding process of the workpiece.

[0043] Workpiece unloading: The processed short shaft workpiece is moved to the unloading position by the rotation conveyor of the work turntable 32. At this time, the short shaft workpiece is located on the slot side of the discharge trough seat 39. Then, the push block drive cylinder 52 drives the sliding support block 54 to drive the unloading push block 53 to move laterally. The unloading push block 53 pushes the short shaft workpiece to the side to flip over and slide out from the inclined slot side of the discharge trough seat 39, thus completing the workpiece unloading.

[0044] In summary, this grinding device adopts an automatic grinding structure. Through the cooperation of the grinding mechanism 2, turntable mechanism 3, feeding mechanism 4, and unloading mechanism 5, it can automatically complete the work of loading, shifting, grinding limit, and unloading of grinding parts, replacing manual labor. It eliminates manual loading and unloading operations, significantly improving the grinding efficiency of automotive parts while reducing labor consumption. Furthermore, it avoids long-term contact between personnel and the metal dust and noise generated during processing, greatly improving the operational safety of grinding. The turntable-type work loading structure uses the work turntable 32 as the work loading structure for short shaft workpieces. Relying on the positioning slot 36 on the upper part of the work turntable 32 and the circumferential support of the ring support 31, it can achieve stable picking and positioning of the workpieces and rapid processing and shifting. The structure is simple and the operation is reliable. The processing can achieve efficient grinding of automotive parts. A limit clamping block 34 is set on the edge of the ring support 31. The limit clamping block 34 is driven by the clamping block drive cylinder 35. After the workpiece arrives at the grinding station, the limit clamping block 34 can achieve stable clamping and limiting of the station without manual assistance in disassembly and assembly, which greatly improves the processing efficiency of the device. On the feeding side, the clamping conveyor belt 41 installed on both sides of the feeding trough seat 38 in a counter-position can achieve efficient and stable feeding and conveying of short shaft workpieces. On the discharging side, the unloading push block 53 driven by the push block drive cylinder 52 pushes the processed short shaft workpiece laterally. With the tilting guide of the discharge trough seat 39, the processed workpiece can be unloaded autonomously. The loading and unloading process is fully automatic, which can greatly improve the production efficiency of the device while reducing the consumption of processing manpower and the intensity of operation.
