Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to an automatic loading and unloading grinder. Background Art

[0002] A grinder is a machine tool that uses a grinding wheel as a cutting tool. The high-speed rotation of the grinding wheel provides the necessary linear speed for workpiece cutting. Grinding machines can achieve high-precision and high-surface quality metal processing and are very suitable for processing hard materials. There are many types of grinders, including surface grinders, cylindrical grinders, internal and external cylindrical grinders, universal grinders, etc. Each grinder has its own design and function for different process requirements. For example, surface grinders are mainly used for flat surface processing, and the workpiece can be fixed on a magnetic worktable, while cylindrical grinders are mainly used for processing cylindrical or conical outer surfaces. The operation of the grinder requires highly skilled operators to control the feed speed of the grinding wheel and the movement speed of the workpiece to obtain the required size and surface roughness. In addition to relying on the accuracy and performance of the machine tool itself, the efficient grinding process is also closely related to the selection of grinding process parameters, such as the type of grinding wheel, the grain size of the grinding wheel, the speed of the worktable, the relative feed rate of the grinding wheel and the workpiece, and the use of coolant.

[0003] In the prior art, a workpiece to be polished is clamped by a three-jaw chuck and then brought into contact with the grinding wheel of a grinder to polish its surface. After polishing, the workpiece is removed from the three-jaw chuck and then manually replaced with the next workpiece to be processed and the above steps are repeated. In this way, each step requires manual participation of the operator, which is not convenient for the automation of the entire process.

[0004] Therefore, an automatic loading and unloading grinding machine is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an automatic loading and unloading grinding machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An automatic loading and unloading grinding machine comprises a connecting frame, a grinding wheel machine 1 arranged on the connecting frame, a transport component and a grinding wheel machine 2, a conveyor 1 and a conveyor 2 arranged on both sides of the connecting frame, and a feeding component, wherein an abrasive channel is formed between the grinding wheel machine 1, the grinding wheel machine 2 and the transport component, and the feeding component controls the workpiece to move from the abrasive channel toward the conveyor 2 at one end of the conveyor 1.

[0008] Preferably, the feeding assembly includes a vertical frame fixedly connected to the connecting frame, a cover shell fixedly connected to the vertical frame, and an electric slide rail fixedly connected to the vertical frame and located in the cover shell.

The piston rod of the cylinder is fixedly connected to a vertically arranged connecting rod. The lower end of the connecting rod is fixedly connected to a horizontal plate and a vertical plate forming an L-shaped structure. A workpiece suction piece is arranged on the vertical plate.

[0009] Preferably, the workpiece suction member is an electromagnet fixedly connected to the vertical plate, and the electromagnet is energized.

[0010] Preferably, there are a plurality of connecting rods, and the lower ends of the plurality of connecting rods are fixedly connected to the transverse plate.

[0011] Preferably, the top surface of the connecting frame is fixedly connected with two support plates located on both sides of the transport component, the top surfaces of the two support plates are both provided with support slopes, and the transport component is arranged between the two support plates.

[0012] Preferably, the transport assembly comprises a transmission roller rotatably arranged between two support plates, and a guide thread is provided on the outer peripheral wall of the transmission roller.

[0013] Preferably, the transport assembly also includes a connecting plate fixedly connected to one end of the two support plates, two rotating shafts, a driving sprocket, a driven sprocket, a chain, a bearing seat, and a servo motor.

[0015] The utility model is specially designed for disc-shaped or cylindrical workpieces. The operator or the loading mechanism only needs to simply put the workpiece on the conveyor one, and it can automatically reach the bottom of the horizontal plate after being conveyed. Through the coordinated action of the cylinder and the connecting rod, the horizontal plate moves stably in the vertical direction, and drives the vertical plate and the electromagnet in the energized state to descend synchronously. When the L-shaped structure covers the workpiece, the electromagnet absorbs one end of the workpiece, and then lifts the workpiece vertically to be coaxially aligned with the abrasive channel. The inner side of the abrasive channel is equipped with multiple grinding wheels and transmission rollers for the workpiece to enter. After the workpiece is fed in, it is guided by the guide thread of the transmission roller and moves smoothly from the conveyor one to the conveyor two. At the same time, the electromagnet circuit is disconnected to remove excess resistance. In the abrasive channel, the inclined surface supports the workpiece, and the grinding wheel machine one and the grinding wheel machine two grind the workpiece comprehensively. At the same time, the workpiece is rotated by the transmission roller to achieve uniform grinding. Such an automated process eliminates the need for operators to grind the workpiece by hand, greatly improving the efficiency and automation of the grinding operation.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] An automatic loading and unloading grinding machine, such as Figure 1 and 3As shown, it includes a connecting frame 17, a grinding wheel machine 1 arranged on the connecting frame 17, a transport assembly and a grinding wheel machine 2, a conveyor 10 and a conveyor 2 11 arranged on both sides of the connecting frame 17, and a feeding assembly. An abrasive channel is formed between the grinding wheel machine 1, the grinding wheel machine 2, and the transport assembly. The feeding assembly controls the workpiece to move from the abrasive channel toward one end of the conveyor 10 toward the conveyor 2 11.

[0023] like Figure 1 , 2 As shown in 4, the feeding assembly includes a vertical frame 3 fixedly connected to the connecting frame 17, a cover shell 4 fixedly connected to the vertical frame 3, and an electric slide rail fixedly connected to the vertical frame 3 and located in the cover shell 4. The cover shell 4 is strip-shaped and has an opening formed on its bottom surface. A cylinder 5 is fixedly connected to the slide seat of the electric slide rail, which is in contact with the inner wall of the cover shell 4 and passes through the opening. The piston rod of the cylinder 5 is fixedly connected to a vertically arranged connecting rod 6. The lower end of the connecting rod 6 is fixedly connected to a horizontal plate 7 and a vertical plate 8 forming an L-shaped structure. There are several connecting rods 6, and the lower ends of several connecting rods 6 are fixedly connected to the horizontal plate 7. A workpiece suction piece is arranged on the vertical plate 8. The workpiece suction piece is an electromagnet 9 fixedly connected to the vertical plate 8, and the electromagnet 9 is energized.

[0024] like Figure 2 and 4 As shown, the top surface of the connecting frame 17 is fixedly connected with two support plates 12 located on both sides of the transport component, and the top surfaces of the two support plates 12 are provided with support inclined surfaces 13. The transport component is arranged between the two support plates 12. The transport component includes a connecting plate 14 fixedly connected to one end of the two support plates 12, a transmission roller 15 rotatably arranged between the two support plates 12, two rotating shafts, a driving sprocket, a driven sprocket, a chain, a bearing seat, and a servo motor. A guide thread 16 is arranged on the outer peripheral wall of the transmission roller 15. The bearing seat is fixedly connected to the top surface of the connecting frame 17 and is located between the abrasive channel and the conveyor 11. The two rotating shafts are respectively fixedly connected to the two ends of the transmission roller 15, one rotating shaft is rotatably connected to the connecting plate 14, and the other rotating shaft is fixedly connected to the inner ring of the bearing seat, and the driven sprocket is fixedly connected to the rotating shaft arranged toward the bearing seat. The servo motor is also fixedly connected to the top surface of the connecting frame 17, and the driven sprocket is fixedly connected to the output shaft of the servo motor. The chain transmission connects the driving sprocket and the driven sprocket.

[0025] In the process of transporting disc-shaped or cylindrical workpieces, the utility model only needs an operator or a loading mechanism to place the workpieces one by one on the conveyor 10. Through the transportation of the conveyor 10, the workpieces can reach the bottom of the horizontal plate 7, and then the cylinder 5 can drive a plurality of connecting rods 6 to move in the vertical direction through the piston rod, so that the horizontal plate 7 is more stable when it moves in the height direction. When the horizontal plate 7 descends, it will also drive the vertical plate 8 and the electromagnet 9 to descend together. At this time, the electromagnet 9 remains energized and has a certain magnetic force. When the horizontal plate 7 and the vertical plate When the L-shaped structure cover composed of 8 is arranged on the outside of the workpiece, the electromagnet 9 will generate magnetic force on one end of the workpiece, so that it is adsorbed on the electromagnet 9. Subsequently, the cylinder 5 pulls the horizontal plate 7, the vertical plate 8, the electromagnet 9, and the workpiece to rise through the piston rod and the connecting rod 6 until the workpiece is coaxially arranged with the abrasive channel. The specific abrasive channel is a wide space that maintains a tangent state with the grinding wheel of the grinder 1, the grinding wheel of the grinder 2, the two supporting inclined surfaces 13, and the transmission roller 15. When the workpiece needs to enter the abrasive channel, it only needs the electric slide rail to drive the cylinder 5 The workpiece 10 is displaced by the guide thread 16 on the outer wall of the transmission roller 15 during the rotation of the transmission roller 15, and the workpiece is displaced from the conveyor 10 to the conveyor 11. At the same time, the circuit where the electromagnet 9 is located only needs to be temporarily powered off, so that there will be no additional friction when the friction component guides the workpiece. The resisting force appears. When the workpiece enters the abrasive channel, it can not only be supported by the supporting inclined surfaces 13 on the two supporting plates 12, but also be polished by the grinding machines 1 and 2. In the process of being transported by the transmission roller 15, the workpiece can also rotate in the abrasive channel, thereby ensuring that the workpiece that leaves the abrasive channel and falls onto the conveyor 2 11 can fully complete the polishing work. In this way, there is no need for the operator to manually hold the workpiece and cooperate with the grinder for polishing, which greatly improves the working efficiency and automation process of the grinder.
