Description

Technical Field

[0001] This utility model relates to the field of fastener testing technology, and in particular to a testing tray for metal fasteners. Background Technology

[0002] Metal fasteners come in a wide variety of types and are small in size. To improve inspection efficiency, optical inspection equipment is often used. To cooperate with optical inspection, fasteners need to be supported and placed on a rotating platform. However, the existing rotating platforms have a simple structure and mostly use a smooth-surfaced disc design, which results in very limited stability of metal fasteners. Moreover, they cannot cooperate with optical equipment to conduct comprehensive inspection of metal fasteners, resulting in a long inspection stroke. Utility Model Content

[0003] The technical problem this invention aims to solve is that the existing rotating platform has a simple structure, the stability of metal fasteners is very limited, and it cannot be used in conjunction with optical equipment to fully inspect metal fasteners, resulting in a long inspection stroke.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a test tray for metal fasteners, including a circular tray body, a metal support frame is bolted to the lower end of the circular tray body, a transmission gear ring is fixedly assembled at the bottom of the metal support frame, a plurality of circular assembly through holes are opened at the upper end of the circular tray body, a bottom support seat is movably assembled inside the circular assembly through holes, and an upwardly protruding arc-shaped limiting frame is provided at the edge of the upper surface of the bottom support seat.

[0005] The bottom limiting bracket is bolted to the lower opening position of the circular assembly through hole.

[0006] A synchronous adjustment gear is axially fixed at the lower end of the bottom support.

[0007] The bottom limiting bracket has a ball bearing installed on its inner bottom surface for assembling the bottom support seat.

[0008] The circular pallet body has an inner unloading port located inside the circular assembly through hole.

[0009] The bottom limiting bracket has a threaded sidewall fitted with a lateral locking bolt for fixing the ball bearing.

[0010] The beneficial effects of this utility model are:

[0011] (1) The metal fastener testing tray of this utility model uses a transmission gear ring on the metal support frame at the lower end of the circular tray body to control the rotation and adjustment of the circular tray body through a power unit, which is convenient to drive and has high efficiency.

[0012] (2) A bottom support seat is movably mounted inside the circular mounting through hole at the upper end of the circular tray body. The bottom support seat is synchronously driven by the rotation of the circular tray body, which drives the metal fastener to rotate and adjust, thereby improving the range and accuracy of optical scanning.

[0013] (3) An upward-protruding arc-shaped limiting frame is provided at the edge of the upper surface of the bottom support base, which can improve the limiting ability of the metal fastener and ensure stability. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of the upper structure of this utility model.

[0016] Figure 2 This is a schematic diagram of the bottom structure of this utility model. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 and Figure 2 The test tray for metal fasteners shown includes a circular tray body 1. A metal support frame 2 is bolted to the lower end of the circular tray body 1. A transmission gear ring 3 is fixedly assembled at the bottom of the metal support frame 2. The upper end of the circular tray body 1 has 36 circular assembly through holes. A bottom support seat 4 is movably assembled inside the circular assembly through holes. The upper surface edge of the bottom support seat 4 has an upwardly protruding arc-shaped limiting frame 5.

[0020] Working principle: The metal fastener is guided onto the upper surface of the circular tray body 1 via the input guide rail. Then, the metal fastener slides onto the upper surface of the bottom support seat 4. The power unit controls the circular tray body 1 to rotate via the transmission gear ring 3. When it rotates to the optical detection position, the bottom support seat 4 is driven to rotate via the arc-shaped rack at the assembly end. This controls the metal fastener to rotate while it is being optically detected, thereby expanding the detection range.

[0021] To accommodate the bottom limit, a bottom limit bracket 6 is bolted to the lower opening of the circular assembly through hole.

[0022] To facilitate bottom drive adjustment, a synchronous adjustment gear 7 is axially fixed at the lower end of the bottom support 4.

[0023] An arc-shaped rack that engages with the synchronous adjustment gear 7 is fixed inside the assembly groove of the circular tray body 1. When the circular tray body 1 rotates, the bottom support seat 4 passes through the arc-shaped rack, and the synchronous adjustment gear 7 meshes with the arc-shaped rack, controlling the rotation of the synchronous adjustment gear 7, which in turn drives the bottom support seat 4 to rotate, thereby driving the metal fastener to rotate synchronously. At this time, the optical inspection equipment will perform a surround inspection on the periphery of the metal fastener.

[0024] To reduce rotational friction, a ball bearing 8 for assembling the bottom support 4 is installed on the inner bottom surface of the bottom limiting bracket 6.

[0025] The bottom support 4 is inserted into the ball bearing 8 via the bottom shaft and connected to the ball bearing 8.

[0026] To facilitate unloading, an inner unloading port 9 is provided inside the circular assembly through hole of the circular pallet body 1.

[0027] When the inspection is passed or failed, the bolts are blown away by high-pressure air through the outer high-pressure nozzle, and then the metal fasteners are dropped and separated through the inner discharge port 9.

[0028] To facilitate loading, unloading, and fixing, the bottom limiting bracket 6 is threaded with lateral locking bolts 10 for fixing the ball bearing 8.

[0029] The ball bearing 8 is installed and fixed by threading the side locking bolt 10 onto the bottom limiting bracket 6, thereby pressing it inward against the side wall of the ball bearing 8.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
