Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a high-precision machining center saddle. Background Technology

[0002] In today's precision machining field, the accuracy of machining centers is a key factor determining product quality. As a crucial support and moving component of the machining center, the performance of the saddle directly impacts machining accuracy. Traditional saddles generally suffer from several insurmountable problems. For example, under prolonged high-speed, high-load machining conditions, structural design flaws in the saddle can lead to a gradual deterioration in its levelness, resulting in reduced workpiece dimensional accuracy and a significant increase in scrap rates. Furthermore, the saddle's levelness cannot be automatically adjusted, thus failing to meet the ever-growing demands of modern manufacturing for high-precision machining. Therefore, a high-precision machining center saddle is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a high-precision machining center saddle. A leveling sensor detects the saddle's horizontality and transmits this information to a controller. When the saddle is not in a horizontal position, the controller extends and retracts an electric push rod, causing the saddle to rotate and fine-tune its angle until it is level. This ensures the dimensional accuracy of the workpiece, reduces the scrap rate, and overcomes the deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-precision machining center saddle includes guide rails, with connecting plates fixed between adjacent ends of two guide rails, and L-shaped clamping plates fixed at the upper ends of both guide rails. U-shaped sliders are slidably engaged on the horizontal sections of the two L-shaped clamping plates, and a support plate is connected between the two U-shaped sliders. A mounting hole is provided on one side of the support plate, and a saddle is rotatably mounted at the mounting hole. A leveling mechanism is provided on the saddle.

[0006] As a further improvement of this utility model: a mounting groove is provided at the bottom of one end of the saddle, and an extension plate is provided at the bottom of the other end of the saddle. The lower end of the extension plate is rotatably connected to the support plate at the mounting hole via a connecting pin.

[0007] As a further embodiment of this utility model: the leveling mechanism includes an electric push rod rotatably mounted on the top of the mounting groove, the lower end of the electric push rod being rotatably mounted on the top of the support plate, and a leveling sensor being fixed on one side of the mounting groove.

[0008] As a further improvement of this utility model: a controller is installed on one side of the upper end face of the support plate, and the electric push rod and the leveling sensor are both electrically connected to the controller.

[0009] As a further embodiment of this utility model: a connecting column is fixed in the middle of the lower end face of the support plate, a threaded rod is rotatably mounted in the middle of one of the connecting plates via a bearing, and a servo motor is mounted on the other connecting plate, with the output end of the servo motor connected to one end of the threaded rod.

[0010] As a further improvement of this utility model: both L-shaped plates are welded to the upper ends of two guide rails, and both ends of the two guide rails are provided with fixing holes.

[0011] The beneficial effects of this utility model are as follows:

[0012] The leveling sensor detects the horizontality of the saddle and transmits the horizontality information to the controller. When the saddle is not in a horizontal position, the controller controls the electric push rod to extend and retract, which drives the saddle to rotate and achieves fine adjustment of the saddle angle until the saddle is adjusted to a horizontal position, thereby ensuring the dimensional accuracy of the workpiece and reducing the scrap rate.
