Description

Technical Field

[0001] This utility model relates to an angle adjustment device, and more particularly to an electric arc swing table. Background Technology

[0002] An electric arc swing table is a device used to adjust the tilt angle. Existing adjustment structures mostly use a worm gear and worm wheel combination to drive it. This structure has high precision requirements, so the parts are difficult to process and the product manufacturing cost is high.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an electric arc swing table to solve the problem of high product manufacturing cost mentioned in the background art.

[0005] The technical solution of this utility model is as follows: An electric arc swing table is provided, comprising: a driving assembly, a fixing assembly, and a sliding assembly; the driving assembly includes: a motor, a ball screw connected to the output shaft of the motor, a screw nut cooperating with the ball screw, and a push frame connected to the screw nut; the fixing assembly includes: a base with a movable groove and an arc-shaped groove, a first support bearing and a second support bearing mounted on the base; both ends of the ball screw are respectively mounted on the inner rings of the first support bearing and the second support bearing; the sliding assembly includes: a support plate, an arc-shaped plate connected to both sides of the support plate, a fixed shaft connected to the lower surface of the support plate, and a movable bearing mounted on the fixed shaft; the arc-shaped plate cooperates with the arc-shaped groove, the push frame is provided with a bearing groove, and the movable bearing cooperates with the bearing groove. The first support bearing and the second support bearing are used to support the ball screw.

[0006] The motor operates, driving the ball screw to rotate, which in turn drives the screw nut to move along the ball screw, which in turn moves the pusher frame. The movement of the pusher frame then moves the movable bearing. Because the arc-shaped plate cooperates with the arc-shaped groove, the tilt angle of the support plate can be adjusted. Since a worm gear precision-fit structure is not required, the machining accuracy of the parts can be reduced, thus lowering the product manufacturing cost.

[0007] Furthermore, the base includes: a base plate, side pieces connected to both sides of the base plate, and end pieces connected to both ends of the base plate; the base plate, side pieces, and end pieces form a movable groove.

[0008] Furthermore, the base also includes: a ball bearing; a first arc-shaped guide groove is provided on the side member, and a second arc-shaped guide groove is provided on the arc-shaped plate; the ball bearing is sandwiched between the first arc-shaped guide groove and the second arc-shaped guide groove. The ball bearing enables the sliding component to swing smoothly without jerking.

[0009] Furthermore, the base also includes a ball retainer mounted on the side member, the ball retainer having ball holes, and the balls being disposed in the ball holes. The ball retainer is used to restrict the position of the balls, preventing the balls from rolling freely in the first arc-shaped guide groove and the second arc-shaped guide groove.

[0010] Furthermore, the base also includes: a first support seat and a second support seat respectively installed on both ends of the base plate, and the first support bearing and the second support bearing are respectively installed on the first support seat and the second support seat.

[0011] Furthermore, the push frame includes: a first push member and a second push member connected to the first push member; the first push member and the second push member form a bearing groove, and the push frame is connected to the side wall of the moving groove via a cross roller guide. By adjusting the distance between the first push member and the second push member, the size of the bearing groove can be adjusted, thereby enabling better matching of the moving bearing.

[0012] Furthermore, the electric arc swing stage also includes: several sensors mounted on one side of the base, and several sensing plates mounted on the arc-shaped plate; the movement trajectory of the sensing plates passes through the sensing range of the sensors. Preferably, the sensors are slot-shaped photoelectric sensors. The sensing plates cooperate with the sensors to determine the tilt angle of the support plate.

[0013] Furthermore, a scale is provided on the arc-shaped plate, and a scale indicator is provided on the base, with the scale indicator pointing to the scale.

[0014] Furthermore, the output shaft of the motor is connected to a ball screw via a coupling.

[0015] Furthermore, the electric arc swing table also includes a connecting frame that connects the motor and the base.

[0016] By adopting the above solution, this utility model provides an electric arc swing table, which uses a moving bearing to push the tilting angle. The structure is simple and the transmission is efficient. It does not require a worm gear precision matching structure, thereby reducing the machining accuracy of parts and reducing product manufacturing costs. Attached Figure Description
