Through this setting, after the part is placed on the processing table, the operator manually presses the part on the processing table to limit its vertical movement, and then pushes the processing table to move on the track. The operation process is more convenient.

Preferably, each of the grinding discs is sleeved with a protective cover, and the protective cover is provided with a processing port for the entry of parts.

Preferably, a backing plate is fixed on the side away from the grinding plate of the processing table, and the backing plate is perpendicular to the transmission shaft.

The advantage of the utility model lies in that the grinding discs are symmetrically arranged on both sides of the processing table, and two processing tables are arranged. When the operator pushes the part, the two sides of the part will be ground by the grinding discs located on both sides at the same time. , and the equipment can process two parts at the same time. This setting is not only easy to operate, but also has strong practicability, and greatly improves the work efficiency and production capacity of the equipment. The setting of the processing port and the protective cover isolates the debris generated by the grinding disc during the processing, and protects the operator.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

A grinding machine, as shown in FIG. 1 , includes a frame 1, and a grinding mechanism and a processing table 2 for placing the parts to be processed are arranged on the frame 1. The grinding mechanism includes a transmission shaft 3, a driving mechanism and a grinding disc 4. A bearing 5 is arranged on the frame 1. The outer ring of the bearing 5 is fixed with the frame 1, and the inner ring of the bearing 5 is fixed with the transmission shaft 3. The transmission shaft 3 is rotatably connected with the frame 1 through the bearing 5 . Two grinding discs 4 are provided and are respectively fixed on both ends of the transmission shaft 3 , and the rotational axis of the grinding discs 4 is in the same direction as the axial direction of the transmission shaft 3 . At the same time, there are also two processing tables 2 , and the two processing tables 2 are located at two ends of the transmission shaft 3 respectively. The driving mechanism includes a motor 6, and a belt (not shown in the figure) is wound around the output shaft of the motor 6, and the output shaft of the motor 6 is connected to the transmission shaft 3 in a driving manner through the belt. There are two grinding mechanisms, and they are symmetrically arranged on both sides of the processing table 2 .

When the equipment is working, start the motor 6, the rotation of the output shaft of the motor 6 will drive the transmission shaft 3 to rotate through the belt, and the rotation of the transmission shaft 3 will finally drive the grinding disc 4 that is fixedly connected to it to rotate synchronously. At this time, the equipment enters the working state. The operator only needs to place the part to be processed on the processing table 2, and then push the part to be close to the grinding plate 4 for grinding. Because the grinding plate 4 is symmetrically arranged on both sides of the processing table 2, when the operator pushes the part , the two sides of the part will be ground at the same time by the grinding discs 4 located on both sides, and the setting of two processing tables 2 can enable the equipment to process two parts at the same time. This setting is not only easy to operate, but also practical. It also greatly improves the working efficiency and production capacity of the equipment.

More preferably, two parallel guide rails 8 are fixed on the frame 1 , and at the same time, the guide rails 8 are arranged in parallel with the transmission shaft 3 . Four rollers 9 are rotatably connected to the bottom of the processing table 2. The four rollers 9 are located at the four corners of the processing table 2 respectively. After the part is placed on the processing table 2, the operator manually presses the part on the processing table 2 to limit its vertical movement, and then pushes the processing table 2 to move on the track. more convenient.

More preferably, a protective cover 10 is sleeved on the outside of each grinding plate 4, the protective cover 10 is fixed to the frame 1, and a processing port is opened on the protective cover 10 for the parts to enter the interior and the grinding plate 4 for lamination processing. 11. This setting protects the operator, isolates the debris generated by the grinding plate 4 during the processing, and avoids the occurrence of personal injury to the operator caused by the debris splashing out.

A backing plate 7 is fixed on the processing table 2 on the side away from the processing table 2 , and at the same time, the backing plate 7 and the transmission shaft 3 are perpendicular to each other. When the equipment is processing rectangular plate-shaped parts, the operator can perform preliminary positioning by leaning one side of the part against the backing plate 7. The positioning structure is simple to set up and has the effect of speeding up the positioning of the parts.

The specific working process: when the parts need to be processed, start the motor 6, the rotation of the output shaft on the motor 6 will drive the transmission shaft 3 to rotate through the belt, and when the transmission shaft 3 rotates, it will drive the grinding disc 4 to rotate synchronously. In the working state, the operator only needs to place the parts to be processed on the processing table 2, then press the parts by hand, and finally push the processing table 2 to move on the guide rail 8, and the parts are immediately removed from the processing port 11 on the protective cover 10. It enters into and is in close contact with the grinding piece 4 to perform grinding processing.

For those skilled in the art, various other equivalent changes and deformations can be made according to the above technical solutions and concepts, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
