Description

Technical Field

[0001] The utility model belongs to the technical field of tooling for end face grinders, and particularly relates to a novel high-efficiency feeding tooling. Background Art

[0002] In the process of machining circular workpieces such as bearings on a double-end surface grinder, the feed tray occupies a core position in the double-end surface grinder. It accurately controls the transportation of the workpieces to ensure that each workpiece can enter the grinding area accurately and stably. This not only ensures the high precision of grinding, but also greatly improves the overall production efficiency and processing quality. However, the feed tray itself does not have the function of feeding into its own positioning groove, and it is also necessary to be equipped with corresponding feeding tooling to feed the positioning groove of the feed tray. In this regard, the prior art discloses a special feeding device for a vertical double-end surface grinder (publication number CN103769998A), which is used to supply workpieces to the feed tray. Although the loading device can continuously feed the feeding tray, it still has defects. The specific problem is that when the diameter of the workpiece changes, when adjusting the spacing between the three adjustment frames, since only a single adjustment frame can be adjusted in turn, it is impossible to ensure that each adjustment frame is equidistant from the axis of the workpiece, resulting in the workpiece being unable to maintain a horizontal state between the three adjustment frames and being tilted. This will not only cause the workpiece to collide with the adjustment frame during feeding, causing damage to the surface, but will also cause jamming, affecting the accuracy and stability of feeding. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides an efficient feeding tooling which can quickly and synchronously adjust three adjustment frames to avoid jamming, so as to solve the above-mentioned problems.

[0004] The utility model discloses a novel high-efficiency feeding tool, comprising a circular ring, wherein the circular ring is provided with three T-rails in an axially rotating array, an L-shaped adjustment frame is slidably arranged in each of the T-rails, a tooth groove is arranged at the bottom of the adjustment frame, a rotationally connected tooth ring is coaxially arranged at the bottom of the circular ring, a spiral clamping tooth matched with the tooth groove is arranged at the top of the tooth ring, a downwardly extending bracket is arranged on the circular ring, a slide plate located below the tooth ring is arranged on the bracket, baffles are arranged on both sides of the slide plate, a push plate is arranged on the top of the slide plate, a telescopic mechanism is arranged at the bottom of the slide plate, and the telescopic end of the telescopic mechanism is connected to the push plate.

[0005] Furthermore, the outer ring of the gear ring is provided with a gear ring, and the bracket is provided with an adjusting gear meshing with the gear ring.

[0006] Furthermore, a V-shaped groove is provided on the end surface of the push plate, and the bottom is chamfered.

[0007] Furthermore, a plurality of rollers are arranged on the push plate.

[0008] Furthermore, a row of rubber shafts is arranged on the inner side of the adjustment frame.

[0009] Furthermore, the telescopic mechanism is a telescopic cylinder, and the telescopic mechanism is detachably connected to the push plate.

[0010] Furthermore, a mounting base is provided at the bottom end of the bracket.

[0011] Compared with the existing technology, the feeding device can quickly and synchronously adjust the three adjustment frames so that the workpiece can remain coaxial and horizontal with the ring, effectively avoiding collision damage and conveying jams, thereby achieving efficient feeding.

[0018] See also Figures 1 to 3The utility model is a new type of efficient feeding tool, comprising a circular ring 1, wherein the circular ring 1 is provided with three T-rails 2 in an axial rotation array, wherein an L-shaped adjustment frame 3 is slidably arranged in each of the T-rails 2, wherein a tooth groove 4 is arranged at the bottom of the adjustment frame 3, wherein a rotationally connected tooth ring 5 is coaxially arranged at the bottom of the circular ring 1, wherein a spiral clamping tooth 6 meshing with the tooth groove 4 is arranged at the top of the tooth ring 5, wherein the three adjustment frames 3 are driven to converge inward or diverge outward in their respective corresponding T-rails 2 by rotating the tooth ring 5 and meshing with the spiral clamping tooth 6 on the tooth ring 5 and the tooth groove 4. The three adjustment frames 3 form a limiting structure to limit the outer ring of the workpiece, and the workpiece can fall freely from the center holes of the circular ring 1 and the tooth ring 5. The circular ring 1 is provided with a bracket 7 extending downward, wherein the bracket 7 is provided with a slide plate 8 located below the tooth ring 5, wherein baffle plates 9 are arranged on both sides of the slide plate 8, wherein the baffle plates 9 and the slide plate 8 form a feeding channel for feeding the material to the slot on the feeding tray. A push plate 10 is provided on the top of the slide plate 8, and a telescopic mechanism 11 is provided on the bottom of the slide plate 8, and the telescopic end of the telescopic mechanism 11 is connected to the push plate 10.
