Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grinding machine blanking, specifically a steel ball blanking assembly for a centerless grinding machine. Background Technology
[0002] A centerless grinder is a grinding machine that grinds a workpiece without requiring a workpiece axis for positioning. A centerless grinder includes two grinding wheels and a support structure located between them. The space between the two grinding wheels is the grinding space. The two grinding wheels are used to grind the outer peripheral wall of the outer ring of a spherical product. The support structure supports the outer ring of the bearing, and one of the grinding wheels can move horizontally to clamp the spherical product.
[0003] Currently, after grinding the outer ring of spherical products, centerless grinders generally need to use a pusher mechanism (usually a cylinder) to discharge the spherical products from the discharge port of the centerless grinder. This undoubtedly increases the cost of equipment components and equipment, so improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a steel ball feeding assembly for a centerless grinder, so as to solve the problems of numerous equipment parts and high cost in the existing feeding methods mentioned in the background art.

[0006] As a preferred option, to further achieve rapid material unloading, the support frame is provided with a material unloading guide channel that cooperates with the material unloading guide bracket.
[0007] Preferably, for ease of disassembly, the material guide bracket is provided with one or more mounting through holes, and the support frame is provided with screw holes aligned with the mounting through holes. A locking screw passing through the mounting through hole is threaded into each screw hole.
[0008] Preferably, to facilitate fine-tuning of the top material frame, one or more U-shaped through holes are provided on both sides of the top material frame, and the support frame is provided with screw holes two aligned with the U-shaped through holes, with a locking screw two threaded through the U-shaped through hole on each screw hole two.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0022] Example 1
[0023] Please see Figures 1-6 This embodiment discloses a steel ball feeding assembly for a centerless grinder, including a frame 1. A support frame 2 located within the grinding space is disposed above the frame 1. A top feed frame 3 is disposed above the support frame 2. A top feed plate 4 is disposed inside the top feed frame 3. Two support members 5 are disposed on the upper side of the top feed plate 4. The upper surface of each support member 5 is provided with an inclined platform 6 for placing steel balls. An inclined guide surface 7 is disposed above the top feed frame 3. The high end of the inclined guide surface 7 is flush with the low end of the inclined platform 6. An inclined feeding guide bracket 8 is disposed on the side of the support frame 2. The high end of the frame 1 is connected to the inclined guide surface 7. The side of the frame 1 is provided with a material storage rack 9 that is connected to the low end of the material guide support 8. In this structure, due to the inclined setting of the material guide support 8, rapid material feeding is achieved under the action of gravity. Preferably, the front and rear discharge positions can be selected according to the installation requirements. The frame 1 is provided with a material storage rack 9 at both the front and rear to further achieve rapid material feeding. The support frame 2 is provided with a material guide channel 10 that cooperates with the material guide support 8. The material guide channel 10 can be used to quickly transport the steel balls into the material storage rack 9 to achieve rapid material feeding.
[0024] Preferably, for ease of disassembly, the material guide bracket 8 is provided with one or more mounting through holes 11, and the support frame 2 is provided with screw holes 12 aligned with the mounting through holes 11. Each screw hole 12 is threaded with a locking screw 13 that passes through the mounting through hole 11. With the above structural design, it is convenient to disassemble the material guide bracket 8 in the future.
[0025] Preferably, to facilitate fine-tuning of the top material frame 3, one or more U-shaped through holes 14 are provided on both sides of the top material frame 3. The support frame 2 is provided with screw holes 15 aligned with the U-shaped through holes 14. Each screw hole 15 is threaded with a locking screw 16 that passes through the U-shaped through hole 14. The above structure allows for appropriate adjustment of the installation position of the top material frame 3 by loosening the locking screws 16, so that it can be fine-tuned according to the installation position of the grinding wheels on both sides, thereby further improving the accuracy of subsequent grinding.
[0026] Preferably, for ease of disassembly, the support frame 2 is provided with lifting platforms 17 on both sides. Each lifting platform 17 is provided with one or more mounting through holes 18. Each mounting through hole 18 is fitted with a locking screw 19 that is threaded to the frame 1. The lifting platform 17 is covered with a dust cover 20. The dust cover 20 is threaded to the side of the support frame 2 by a locking screw 21. This structure hides the lifting platform 17 and the locking screw 19 by adding a dust cover 20, preventing the steel ball from colliding with the locking screw 19 and damaging its surface when it is being fed, while also providing dust protection.
[0027] In use, since two grinding wheels are installed on the frame 1 and the support frame 2 is located in the grinding space between the two grinding wheels, during operation, the steel ball is placed on the inclined table 6 by the feeding mechanism, and then the steel ball is clamped by the two grinding wheels and ground by rotating the grinding wheels. After grinding, one set of moving grinding wheels is driven away from the other set of grinding wheels. Finally, the two sides of the steel ball are not pressed together. At this time, the steel ball falls into the unloading guide bracket 8 through the inclined guide surface 7, and then falls into the unloading storage rack 9, realizing automatic unloading. Therefore, with this structure, the steel ball can be unloaded quickly without the need for an additional pushing mechanism, and the number of parts is reduced, thus reducing equipment costs.
[0028] It should also be noted that the specific structure of the two grinding wheels on the frame 1, and how one of the grinding wheels moves, are all conventional technologies in the field, and therefore will not be described in detail.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
