Automatic hinge assembling device

Abstract

The invention discloses an automatic hinge assembling device which is characterized in that an inner strip assembly positioning surface for placing an inner strip assembly is arranged on the top surface of a carrier, an arm body positioning surface for placing an arm body is arranged on the top surface of the carrier, a first groove extending downwards is formed in the position, between the inner strip assembly positioning surface and the arm body positioning surface, of the top surface of the carrier, and a plastic round pipe is placed in the first groove; a supporting block is inserted into the bottom of the first groove in a lifting sliding mode, and the top face of the supporting block is provided with a round pipe positioning face matched with the side wall of the plastic round pipe in shape and used for containing the plastic round pipe. The conveying device is used for conveying the carrier to move; the multiple nail penetrating machines are distributed on any side of the conveying device and used for inserting connecting nails into connecting holes of workpieces on the carriers, the multiple nail penetrating machines comprise the first nail penetrating machine, and when the conveying device conveys the carriers to sequentially pass through the multiple nail penetrating machines, the first nail penetrating machine firstly passes through the second nail penetrating machine; the first nail penetrating machine is used for inserting connecting nails into connecting holes in the inner strip assembly, the plastic round pipe and the arm body. According to the hinge part assembling device, stable and efficient assembling of hinge parts is achieved.

Description

technical field [0001] The invention relates to the field of hinge assembly equipment, in particular to an automatic hinge assembly device. Background technique [0002] The hinge is usually formed by riveting or screwing multiple parts such as arm body, base, cup head, four-hole parts, etc., among which there are small parts such as torsion springs, plastic round tubes, U nails, etc. at the joints of each part. The hinge with buffer function needs to further install the inner strip assembly containing the buffer damping tube. When the hinge is assembled as a whole, each component needs to align the connection holes for assembly, and the hinge components are fine and irregular, and usually need to be manually adjusted and positioned. This leads to low production efficiency, long production cycle, low positioning accuracy, and difficulty in guaranteeing yield. For example, the positioning carrier with the application number of 202010675404.6, it first fits the entire outer w...

Problems solved by technology

[0002] Hinges are usually connected by riveting or screwing multiple parts such as arm body, base, cup head, four-hole parts, etc. There are also tiny parts such as torsion springs, plastic round tubes, U nails, etc. at the joints of each part. The hinge with cushioning function needs to be further installed with an inner strip assembly containing a cushioning damping tube. During the overall assembly of the hinge, each component needs to be assembled by aligning the connection holes, and the hinge components are fine and irregular, and usually require manual adjustment and positioning. Leading to low production efficiency, long production cycle, low positioning accuracy, difficult to guarantee the yield rate, etc.

For example, the positioning vehicle with the application number 202010675404.6 first fits the entire outer wall of the arm body for positioning, so that the opening of the arm body faces upwards, so that the inner strip assembly can be placed inside the arm body through the opening of the arm body for installation, and pre-installed on the arm body. Set an opening, and set a support rod on the carrier to pass through the opening and enter the inside of the arm body to support and position the inner bar assembly placed in the arm body. This positioning carrier requires special holes on the arm body product , which increases the process of the arm body, and also affects the strength of the arm body. After the inner strip components are placed in the arm body, it is very unstable to rely on the small support rod for positioning and support. Stuck inside the vehicle, the nailer cannot be completely close to the nail, which affects the stability of the nail, and the arm body may be slightly deformed after nailing, and the arm body trapped in the vehicle may be difficult to remove

For other components such as plastic round tubes, they are too small to be grasped manually. When they are placed on ordinary vehicles for assembly, due to their light weight, they are easy to roll off due to slight vibrations. Other components also have irregular shapes, Small size, light weight and other issues make it difficult to automatically load the material. At present, manual positioning is mostly used for material loading, and the machine is threaded through the nails.
