Grinding machine capable of grinding uniformly

Abstract

The utility model discloses a grinding machine capable of grinding uniformly, which comprises a roller type conveying platform, a movable platform arranged above the roller type conveying platform and a plurality of groups of grinding machine heads uniformly distributed and mounted on the movable platform, the crank-link mechanism is used for supporting the movable platform to do plane circular motion on the rack on the two sides of the roller type conveying table respectively, and the motor speed reducing unit is used for driving the crank-link mechanism to rotate. According to the grinding machine, the crank connecting rod structure is adopted to support the movable platform to do plane circular motion, and the plane circular motion of the movable platform is uniform motion, so that the grinding uniformity of the grinding machine can be effectively improved. And when the grinding head doing circular motion along with the moving platform returns to the plate, the grinding head is inclined to the plate edge to return, so that the straight surface impact from the plate edge of the plate can be effectively reduced, and the abrasion to the grinding head is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to an improved grinder for uniform grinding. Background Art

[0002] A surface grinder disclosed in the patent document of announcement number CN218364020U is mainly composed of a roller conveyor, a mobile platform above the roller conveyor, and a plurality of groups of grinding heads evenly arranged and installed on the mobile platform. The mobile platform and the frame of the roller conveyor are installed in a manner that they are connected by a linear slide rail for transverse sliding, and the motor drives the mobile platform to make a linear reciprocating motion. The grinding head follows the linear reciprocating motion of the mobile platform, and the metal sheet on the roller conveyor is ground and polished in combination with the self-rotation of the grinding head of the grinding head. During the grinding process, since the grinding head is linearly reciprocating, it is in a stationary state at the moment of the reciprocating turning, and the grinding amount here is relatively large, and the speed of the linear reciprocating motion is not uniform, so there is a problem of uneven grinding for the whole metal sheet. Moreover, the grinding heads arranged at both ends of the mobile platform directly impact the edge of the sheet when the sheet is folded back, and the bristles of the grinding heads are easily worn. Therefore, it is necessary to develop a grinder that can improve the uniformity of grinding and reduce the wear of the grinding head. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a grinding machine which can improve grinding uniformity and reduce the wear of the grinding head.

[0004] The technical solution adopted to solve the above technical problems is: a uniform grinding grinder, including a roller conveyor table, a mobile platform above the roller conveyor table and a plurality of groups of grinding heads evenly arranged and installed on the mobile platform, characterized in that it also includes a crank-connecting rod mechanism for supporting the mobile platform for planar circular motion on the two side frames of the roller conveyor table and a motor reducer unit for driving the crank-connecting rod mechanism to rotate.

[0005] On the basis of the above, the crank-connecting rod mechanism is an eccentric shaft, one of the shafts of the eccentric shaft is connected to the bearing of the moving platform, and the other shaft is connected to the frame bearing of the roller conveyor platform.

[0006] On the basis of the above, the motor reducer unit is installed on the mobile platform, and its reducer output shaft is drivingly connected to the eccentric shaft.

[0007] The beneficial effects brought by the use of the utility model are as follows: since the grinder of the utility model adopts a crank connecting rod structure to support the mobile platform to make a planar circular motion, the planar circular motion of the mobile platform is a uniform motion, which can effectively improve the grinding uniformity of the grinder. Moreover, when the grinding head that follows the mobile platform to make a circular motion returns to the plate, it returns obliquely to the plate edge, which can effectively reduce the direct impact from the plate edge and reduce the wear on the grinding head. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the grinding machine of the utility model. DETAILED DESCRIPTION

[0009] like Figure 1 As shown, a grinding machine for uniform grinding includes a roller conveyor 1, a mobile platform 2 above the roller conveyor 1, and a plurality of groups of grinding machine heads 3 evenly arranged and installed on the mobile platform 2. In the utility model, the grinding machine also includes a crank connecting rod mechanism for supporting the mobile platform 2 for planar circular motion on the two side frames of the roller conveyor 1, and a motor reducer unit 4 for driving the crank connecting rod mechanism to rotate.

[0010] Specifically, the crank connecting rod mechanism is an eccentric shaft 5, one of which is connected to the bearing of the mobile platform 2, and the other is connected to the frame bearing of the roller conveyor 1. In this embodiment, four eccentric shafts 5 are provided, which are placed at the four corners of the mobile platform 2. The motor reducer unit 4 only needs to be connected to one of the eccentric shafts 5, and after starting, it can drive the mobile platform 2 to make a planar circular motion.

[0011] Of course, the motor reducer unit 4 can be installed on the roller conveyor 1 or on the mobile platform 2. In this embodiment, the motor reducer unit 4 is installed on the mobile platform 2, and its reducer output shaft is drivingly connected to the eccentric shaft 4.

[0012] Since the mobile platform 2 is a plane circular motion, it can realize a uniform rotation motion, thus effectively improving the grinding uniformity of the grinder. Moreover, when the grinding head 3.1 follows the mobile platform 2 to make a circular motion, it returns obliquely to the edge of the plate 6, which can effectively reduce the direct impact from the edge of the plate 6 and reduce the wear on the grinding head.
