DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] As attached Figure 1As shown, the present invention provides a servo electric press, comprising a base plate 1, a cylinder fixing plate 2 is fixedly installed on one side of the top of the base plate 1, a servo electric cylinder 3 is fixedly installed on the cylinder fixing plate 2 by means of hexagon socket bolts, the output shaft of the servo electric cylinder 3 passes through the cylinder fixing plate 2, a reinforcing plate 4 is arranged on both the front and rear sides of the cylinder fixing plate 2, a stopper 5 is fixedly installed on the bottom of one end of the inner side of the reinforcing plate 4 away from the cylinder fixing plate 2 by means of screws, a pad 6 is fixedly installed on one side of the top of the base plate 1 away from the cylinder fixing plate 2, and the top of the pad 6 is screwed in place. A support plate 7 is fixedly installed, and a connecting plate 8 is fixedly installed on the top of the support plate 7 close to the cylinder fixing plate 2 by screws. A connecting rod 9 is fixedly installed on the end of the output shaft of the servo electric cylinder 3, and a pressure sensor 10 is fixedly installed on the end of the connecting rod 9 away from the servo electric cylinder 3. A positioning rod 11 is fixedly installed on the side of the pressure sensor 10 away from the connecting rod 9, and a ball foot assembly 12 is threadedly connected to the end of the positioning rod 11 away from the pressure sensor 10. A limiting block 13 is fixedly installed on the side of the connecting plate 8 close to the cylinder fixing plate 2 by screws.

[0018] The output shaft of the servo electric cylinder 3 is transmission connected to the connecting rod 9 .

[0019] The connecting rod 9 and the positioning rod 11 are arranged colinearly.

[0020] The reinforcing plate 4 is fixedly connected to the cylinder fixing plate 2 and the floor 1 by screws.

[0021] The specific implementation method is as follows: when using the present invention, the servo electric cylinder 3 starts to push the connecting rod 9 to move, and then drives the positioning rod 11 through the pressure sensor 10 to push the ball foot assembly 12 to move. When used in conjunction with the limit block 13, the two parts can be effectively pressed together to ensure that the coaxiality of the two parts is within 0.05 during press-fitting. The pressure sensor 10 can accurately measure the size of the press-fitting force. Through the preset press-fitting force value, if the press-fitting force measured by the pressure sensor 10 does not match the preset press-fitting force value, the external alarm is activated to alarm for unqualified press-fitting, thereby avoiding the situation of external crushing. This enables the present invention to effectively press-fit the two parts together to ensure that the coaxiality of the two parts is within 0.05 during press-fitting. At the same time, unqualified press-fitting can be detected to avoid the situation of external crushing.
