Description

Technical Field

[0001] The utility model relates to the technical field of a grinding device for an end face of an engine thrust plate, in particular to a grinding device for an end face of an engine thrust plate. Background Art

[0002] As a kind of engine sliding bearing, thrust plate plays the main role of crankshaft axial support in the engine, ensuring the circumferential rotation of the crankshaft while preventing the crankshaft from axial movement. Double-end face grinder is a highly efficient plane processing machine tool, which can grind two parallel end faces at the same time in one processing process. According to the structure, it can be divided into horizontal and vertical types. According to the feeding method of CNC double-end face grinder, it can be divided into through-type, turntable type and reciprocating type. Due to the high precision and high production efficiency of the ground products, it is widely used in many industries such as automobiles, bearings, and magnetic materials. The piston pins, piston rings, valve washers, connecting rods, cross shafts, valve plates, forks, hydraulic pump blades, rotors, stators, compressor vanes, inner and outer rings and rollers of bearings in the automobile and motorcycle industry, magnetic rings, magnetic steel sheets, graphite plates and other products of various materials in the electronics industry are suitable for processing. The existing thrust plate needs to be end-face ground during processing. To ensure its processing accuracy, a double-end face grinder is required. When the existing double-end face grinder is processing, the thrust plate is generally manually fed into the feed port of the grinder for grinding. This method requires workers to feed the thrust plates into the feed port one by one, so the efficiency of thrust plate processing is low, and long-term operation of the same operation is easy to cause double fatigue to the workers' body and mind. In this case, the operator may make mistakes under fatigue, resulting in unnecessary accidents. The patent name is a straight-through double-end face grinder automatic feeding mechanism for thrust plate processing, which can solve the problem of manual feeding well, but the whole working process is complicated. After multiple working steps, there will be large errors in feeding, and the preparation cost of the equipment will be higher. Utility Model Content

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] End grinding device for engine thrust plate, such as Figure 1 As shown, a grinding device 3 is slidably arranged on a horizontally placed bottom plate 1 through an electric slide rail 2, a thrust plate placement column 5 is fixedly arranged through a support frame 4, and a feeding device 7 is horizontally moved by a linear drive motor 6, and the centers of the rotating grinding disc 33 on the grinding device 3, the thrust plate placement column 5 and the feeding device 7 are located on the same horizontal straight line.

[0020] The rotating motor 32 on the grinding device 3 is fixed on the base 31, the motor shaft of the rotating motor 32 is fixedly connected to the central axis of the rotating grinding disc 33, and the rotating grinding disc 33 is fixedly connected to the base 31 through a bearing seat;

[0021] like Figure 2 As shown, the linear drive motor 6 is fixed in the operating box 9, the motor shaft of the linear drive motor 6 is fixedly connected to the fixed disc 71 of the feeding device 7, and the upper and lower thrust plate push plates 72 are fixedly connected to the fixed disc 71;

[0022] like Figure 3 and Figure 4As shown, the front end face and the rear end face of the thrust plate placement column 5 pass through the upper and lower thrust plate placement through holes 51, and a fixing device 52 is provided at the front end portion of the thrust plate placement column 5, and the fixing device 52 includes an electromagnetic device 8 in a circular shape, and an electromagnet 81 on the electromagnetic device 8 is fixed in the through hole in the thrust plate placement column 5, and one end of the permanent magnet 82 is fixedly connected to the electromagnet 81 by a compression spring, and the other end is suspended, and the permanent magnet 82 is slidably connected to the inner end face of the through hole. The activation of the electromagnet 81 can realize the change of the magnetic force between it and the permanent magnet 82, thereby changing the distance between the electromagnet 81 and the permanent magnet 82, and realizing the distance away from the center point of the thrust plate placement column 5, thereby clamping the thrust plate located in the thrust plate placement through hole 51.

[0023] Before use, first retract the linear drive motor 6 so that there is a certain gap between the feeding device 7 and the thrust plate placement column 5, and then manually place the thrust plates to be polished in the thrust plate placement through holes 51 until they are full;

[0024] Then, the linear drive motor 6 is started, so that the thrust plate pushing plate 72 on the feeding device 7 is pushed into the thrust plate placement through hole 51, so that the thrust plate inside is pushed to the front end surface of the thrust plate placement column 5, so that the outer end surface of the thrust plate is slightly protruded from the front end surface of the thrust plate placement column 5 (which can be sensed by an infrared sensor).

[0025] Then, the electromagnet 81 on the fixing device 5 is started, so that the permanent magnet 82 moves away from the electromagnet 81 until the thrust plate on the same vertical plane as the fixing device 5 is fixedly clamped, and then the electric slide rail 2 is started, so that the grinding device 3 moves on the electric slide rail 2 until the end face of the rotating grinding disc 33 abuts against the end face of the thrust plate. At this time, the rotating motor 32 is started to rotate the rotating grinding disc 33 to grind the convex end face of the thrust plate. In the drawings of the specification, only the end faces of two thrust plates can be grinded at one time. If multiple thrust plate placement through holes 51 are provided on the thrust plate placement column 5, the end faces of multiple thrust plates can be grinded at one time, which can greatly improve the grinding efficiency of the thrust plate.

[0026] After the grinding is completed, the fixing device 52 of the thrust plate is released, and the linear drive motor 6 continues to be used to push the feeding device 7, so that the thrust plate that has been ground will automatically fall off, and the grinding of the end face of the next thrust plate can be achieved.

[0027] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
