Description

Technical Field

[0001] The present application relates to the field of abrasive equipment, and in particular to a multi-station automatic roller transfer and unloading tool. Background Art

[0002] At present, for parts with burrs, chamfered corners, and surfaces that need to be polished, a drum machine is usually used for grinding and polishing. The abrasive particles in the drum are driven by the rotation of the drum to grind and polish the parts in the abrasive in the drum. After the grinding and polishing work is completed, the drum needs to be turned upside down manually or the polished parts in the abrasive need to be picked out manually. The above-mentioned prior art solutions have the following defects: 1. Manually picking out the polished parts from the abrasives requires a lot of labor and there are certain safety hazards. The personnel who pick the materials are easily cut by the sharp finished products. 2. When the drum is turned upside down to discharge materials, there is a large height difference between the drum and the bottom of the container below, which may cause damage to the parts during the discharge process, resulting in a low pass rate or failure of the processed parts; 3. The batch of products to be polished is large, and multiple devices are needed to meet the production needs. The locations for taking and placing materials are scattered during the production process, which requires a lot of manual operation. At the same time, more space is needed to place equipment and materials, resulting in a messy site and waste of manpower. Summary of the invention

[0004] According to the multi-station automatic roller transfer and unloading tooling of the embodiment of the present application, multiple stations are arranged along the length direction of the carrier frame, and each roller is controlled to rotate by an independent reduction motor at each station to realize the processing of spare parts inside a single roller. When batch polishing products, multiple devices arranged at multiple stations operate at the same time to meet production needs. The locations for taking and unloading materials in the production process are concentrated, and there is no need for a large amount of manual operation and placement in multiple sites, thus saving floor space and labor costs.

During the unloading process, the lifting height of the buffer bucket is controlled by the lifting frame to dock with the unloading port of the roller, thereby reducing the splashing of the material to the outside and reducing the unloading of the material. The impact force during the process is reduced. When the roller is discharging, the height drop between the roller and the bottom of the container below is reduced, thereby avoiding damage to the parts during the discharging process, improving the qualified rate of the processed parts, and realizing the collection of materials at the same time; the collected materials are transferred to the side of the sorting screen through the translation mechanism in the buffer bucket, and the blind head is opened to allow the materials in the buffer bucket to enter the sorting screen through the discharge port of the buffer bucket for screening. There is no need to manually pick out the polishing parts in the abrasive, the discharge efficiency is high, and no large amount of labor is consumed, eliminating the safety hazard of people being cut by the finished product when taking materials; the roller is transferred and the discharge operation is performed by the driving mechanism, without manual intervention, saving manpower and material resources, and the operation is fast and stable, which improves work efficiency and eliminates the safety hazards of manual operation; and by setting up multiple workstations, multiple rollers are used to grind and polish the workpiece at the same time, and the settings are staggered according to the grinding and polishing time to achieve continuous grinding and polishing operations.

[0041] When the drum 130 is transferred to the unloading station, the drum cover 150 needs to be opened and closed manually, which is cumbersome, time-consuming and labor-intensive, and reduces labor efficiency. For this reason, the following is a specific implementation plan of the multi-station automatic drum transfer unloading tooling according to the present application with reference to the accompanying drawings: Specifically, if Fig. 9 As shown, in a specific embodiment of the present invention, one side of the drum cover 150 is rotatably connected to the drum 130 via a hinge 151, and a hanging ear 133 is fixed to the end of the drum 130, and a limiting hole is provided on the surface of the hanging ear 133; The cylinder cover 150 is fixed with an internal thread sleeve 170, and a plug 171 is inserted into the internal thread sleeve 170. The external surface of the plug 171 is provided with an external thread, and the external thread cooperates with the internal thread of the internal thread sleeve 170. One end of the plug 171 is inserted into the limiting hole, and the other end of the plug 171 is fixed with a push rod 173.

[0042] After the drum 130 is transferred to the unloading station through the transfer assembly 300, the motor driving the drum 130 to rotate is used to cover the unloading station, so that the unloading port of the drum 130 is downward toward the buffer bucket 500. During the rotation of the drum 130, the end of the paddle 190 overlaps with the baffle 590, so that the baffle 590 pushes the paddle 190, and the paddle 190 drives the push rod 173 to rotate around the latch 171, and the tension spring 193 is stretched during the rotation. At the same time, the latch 171 is axially displaced during the rotation in the internal threaded sleeve 170, so that the end of the latch 171 is disengaged from the limiting hole opened by the hanging ear 133. At this time, the drum cover 150 is placed at the bottom of the drum 130 and rotates around the hinge 151 under the action of gravity, so that the material port of the drum 130 is opened, which is convenient and fast without manual operation, so as to realize continuous transfer and unloading of materials, improve work efficiency, reduce labor costs, and save resources.

[0048] When the drum cover 150 is in the open state, after the latch 171 is disengaged from the limiting hole of the hanging ear 133, the drum 130 is rotated so that the unloading port of the drum 130 is rotated to the upper end. At this time, the drum cover 150 is pressed downward by gravity, so that the inclined surface 1717 on the end face of the slider 1713 contacts the hanging ear 133, and then pushes the slider 1713 to slide and compress the compression spring 1715, so that the drum cover 150 is reset to cover the unloading port of the drum 130. At the same time, the slider 1713 slides to the limiting hole of the hanging ear 133 and is inserted into the limiting hole under the push of the compression spring 1715, thereby locking the drum cover 150, making it convenient to realize the self-locking function by rotating the drum 130 after unloading, and no manual operation is required to realize automated operation.

[0049] In a specific embodiment of the present invention, the two ends of the roller 130 respectively extend outward with a main shaft, the roller 130 is coaxially fixed with any one of the main shafts, a V-shaped support 105 is fixed at the upper end of the carrier frame 100, and the main shaft cooperates to rotate and overlap in a V-shaped groove opened on the surface of the V-shaped support 105.
