[0022] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0023] like Figure 1 , Figure 2As shown, the utility model is a saddle with an automatic table exchange device, comprising a bed 1, a guide rail 2, a motor 3, a reducer 4, a connecting plate 5, a driving wheel 6, a driven wheel 7, a chain 8, a guide plate 9, a table 10, a traction pin 11 and a proximity switch. The bed 1 is a mounting platform for the entire saddle device, and a guide rail 2 is arranged on the bed 1. The guide rail 2 is provided with two, and two guide rails 2 are arranged on both sides of the bed 1 for the roller at the lower end of the table to move. A motor 3 and a reducer 4 are provided under the bed 1, and a connecting plate 5 is provided on the bed 1. The connecting plate 5 can fine-tune the tightness of the chain 8. A driving wheel 6 and a driven wheel 7 are provided on the connecting plate 5. The driving wheel 6 is connected to the output end of the reducer 4. The driving wheel 6 and the driven wheel 7 are connected by a chain 8. The driving wheel 6 drives the driven wheel 7 and the chain 8 to rotate. A guide plate 9 is provided on the side of the bed 1, and the chain 8 rotates along the guide plate 9. A table 10 is provided on the bed 1, and a traction pin 11 is installed on the chain 8. The traction pin 11 cooperates with the slot on the table 10 to drive the movement of the table 10. A proximity switch is provided in the middle groove of the bed 1.
[0024] The proximity switches include a first proximity switch 12, a second proximity switch 13, a third proximity switch 14, a fourth proximity switch 15 and a fifth proximity switch 16. The corresponding positions of the chain 8 are provided with baffles for detecting the position of the table 10.
[0025] The motor 3 and the reducer 4 are fixed to the bed 1 through the connecting plate 5. The driven wheel 7 is fixed to the bed 1 through the bearing 17. A cover plate 18 is also included, and the bed 1 is provided with bolts 19, and the cover plate 18 is fixed to the bolts 19 through screws.
[0026] The function of the guide rail 2: the roller of the table 10 rolls on the guide rail 2; the function of the driving wheel 6, the driven wheel 7, and the chain 8: used for chain transmission, converting the rotational motion of the reducer 4 into the linear motion of the table 10; the function of the guide plate 9: guiding the chain 8 to enhance the stability of the transmission; the function of the traction pin 11: used to pull the table 10 to move with the chain 8.
[0027] The function of the first proximity switch 12 is to stop the reverse rotation of the chain 8; the function of the second proximity switch 13 is to slow down the reverse rotation of the chain 8; the function of the third proximity switch 14 is to slow down the forward rotation of the chain 8; the function of the fourth proximity switch 15 is to detect whether the table 10 exists; the function of the fifth proximity switch 16 is to stop the forward rotation of the chain 8.

[0029] When the machine tool performs table exchange, the initial position of the table is as follows: Figure 3As shown, the motor 3 rotates and transmits the force to the driving wheel 6 through the reducer 4, the chain 8 moves counterclockwise, and the traction pin 11 drives the table 10 to start moving in the negative direction. When the first proximity switch 12 detects the baffle of the chain 8, the motor 3 starts to decelerate. At this time, the table 10 is close to the exchange area. When the second proximity switch 13 detects the baffle, the motor 3 stops rotating and the table 10 stops moving. At this time, the position of the table is as shown in Figure 4 As shown in FIG. 1 , the table 10 has reached the required position for exchange, and the exchange of the table 10 is completed. When the workpiece is processed, the table 10 needs to be replaced. At this time, the table position is as follows: Figure 4 As shown, when the traction pin 11 of the chain 8 hooks the groove of the table, the motor 3 starts to rotate, the chain 8 rotates clockwise, and the table 10 starts to move in the positive direction. When the third proximity switch 14 detects the blocking piece, the motor 3 starts to decelerate. When the fifth proximity switch 16 reaches the blocking piece, the table 10 stops moving. At this time, the position of the table 10 is as shown in FIG. Figure 3 As shown, another table that has already clamped a new workpiece can be exchanged into the processing area.
[0030] The utility model detects the position of the table top by a proximity switch, thereby ensuring the safety and stability of the table top when being exchanged, and drags the table top by a traction pin on a chain, has a simple structure, is flexible and convenient, has a low cost, and enhances the competitiveness of the machine tool in the market.
