Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is the general assembly structure diagram of this embodiment, including the power unit with the linear push rod 22 as the main component, the parallel spring unit with the tension spring 3 as the main part, the ejection operation unit with the locking claw 17 as the main part, and the unlocking block 12 and slide rail 11 are the housing unit of main parts. The upper end of the housing 4 is threadedly connected to the top surface 1, the lower end is fixed to the bottom surface 13 through bolts 15, the ejection limiter 20 is installed on the inner wall of the outer shell 4, and the slide rail 11 is set at the lower end of the ejection limiter 20 on the inner wall of the outer shell 4. Playing the role of ejection guide, the unlocking block 12 is fixedly connected with the bottom surface 13 through bolts 14 .

Abstract

The invention discloses a self-unlocking ejection device with paralleled springs is applied for smaller operation spaces. The technique scheme includes that a direct-current motor (25) is adopted in power drive of an ejection device to drive a straight push rod (22) to stretch springs (3) parallelly arranged, and elastic potential energy is stored; when in a certain distance, an unlocking block (13) performs self-unlocking to a locking component composed of a locking jaw (17) and a jaw mounting seat (19) and the like; the springs (3) stretched drive an operation component composed of a jaw-locking seat (10) and an operation tray (5) and the like to realize ejection operation; and then the straight push rod (22) drives the locking component to be self-locked and return back to normal to complete an ejection circle. Since only one direct-current motor can drive the whole operation process, the locking component is self-unlocked in ejection and self-locked after the ejection, and a plurality of springs are connected with the straight pull rod in parallel, the self-unlocking ejection device with the paralleled springs is simple and convenient to control, strong in ejection force, compact in installation, efficient, and high in reliability.

Description

technical field [0001] The invention relates to a self-unlocking spring parallel ejection device, in particular, a self-unlocking ejection mechanism with large and adjustable ejection force, springs and drives in parallel, which are used in automatic machines with strict operating space requirements. Background technique [0002] With the advancement of science and technology and the improvement of the level of equipment manufacturing industry, various high-quality ejection devices are required in the fields of aviation, aerospace, weapons and industrial automation, especially when there is a restricted space. The existing ejection device is bulky, the ejection force is insufficient and cannot be adjusted, and because there are many motor drives, the control is complicated, and it cannot meet the requirements of the current automation machinery for compactness, high efficiency and high reliability. The self-unlocking spring parallel ejection device is a small-sized ejection ...
