Description

Technical Field

[0001] The utility model relates to the technical field of chain processing, in particular to an automatic assembly device for a chain with an extended pin shaft and accessories. Background Art

[0002] Existing chains with extended pins can only be assembled manually using a six-step, complex press-fit process. This is extremely inefficient and produces inconsistent assembly quality. Extended pin chains can be assembled in various ways, including by lengthening each link, by adding every other link, or by adding multiple links. These chains can suffer from incorrectly assembling long and short pins or the wrong number of links, resulting in financial losses.

[0003] Based on this, the utility model patent with publication number CN209716371U discloses an extended pin chain assembly machine to eliminate the above phenomenon by using automated operations instead of manual operations. However, due to the fixed structure, the extended pin chain assembly machine cannot adapt to the assembly of pins of various diameters. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0024] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected" to another element, the two may be fixed in a detachable manner or in a non-detachable manner, such as socketing, snap-fitting, integrally molded fixing, welding, etc., which can be achieved in the prior art and will not be described in detail here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0027] Combined with attachment Figure 1-Figure 3 , an automatic assembly device for an extended pin chain with accessories in this embodiment includes an assembly table 1, on which a chain conveying mechanism 2, a pin feeding mechanism 3, a pin positioning mechanism 4 and a pin pressing mechanism 5 are provided. The pin feeding mechanism 3 and the pin positioning mechanism 4 are respectively arranged on both sides of the chain conveying mechanism 2, and the pin pressing mechanism 5 is arranged directly above the chain conveying mechanism 2. The pin feeding mechanism 3 includes two adjustment plates 31 arranged at intervals. The spacing between the two adjustment plates 31 is adjustable and forms a feeding channel 32. The feeding channel 32 is arranged perpendicular to the chain conveying mechanism 2. The pin positioning mechanism 4 includes a positioning seat 41 and a positioning head 42. The positioning head 42 abuts against the discharge end of the feeding channel 32 during positioning. The positioning head 42 is provided with a pin positioning groove 43, and the positioning head 42 is detachably connected to the positioning seat 41.

[0028] When in use, the automatic assembly device for the extended pin chain with accessories can adapt to the assembly of pins of various diameters by adjusting the width of the feeding channel 32 and replacing different types of positioning heads 42. The adjustment method is simple and efficient and will not excessively affect the assembly efficiency of the pin chain.

[0029] As a preferred solution of the present invention, a fixing plate 33 is provided on the outer side of the two adjustment plates 31, that is, the two adjustment plates 31 are arranged between the two fixing plates 33, and the fixing plates 33 and the adjustment plates 31 are arranged parallel to each other, the fixing plates 33 are fixedly connected to the assembly table 1, and an adjusting screw 34 is threadedly connected to the fixing plate 33. The adjusting screw 34 is arranged perpendicular to the fixing plate 33, one end of the adjusting screw 34 is rotatably connected to the adjusting plate 31, and the other end of the adjusting screw 34 is arranged on the side of the fixing plate 33 away from the adjusting plate 31. By rotating the adjusting screw 34, the movement and adjustment of the adjusting plate 31 can be controlled, and the operation is very convenient.

[0030] As a preferred solution of the present invention, a guide rod 35 is fixedly connected to the adjustment plate 31, and the guide rod 35 is axially parallel to the adjustment screw 34. The guide rod 35 is arranged along the adjustment direction of the adjustment plate 31 and is guided and inserted into the fixed plate 33. A guide hole that cooperates with the guide rod 35 is provided through the fixed plate 33, and the aperture of the guide hole matches the diameter of the guide rod 35, so as to ensure that the adjustment plate 31 moves back and forth in a fixed direction when the adjustment screw 34 rotates.

[0031] As a preferred solution of the present invention, the two adjusting screws 34 are connected by a transmission structure and rotate synchronously. The purpose of setting the transmission structure is to enable the two adjusting screws 34 to rotate at the same speed, thereby controlling the moving distance of the adjustment plates 31 on both sides to always remain consistent, thereby ensuring that the center of the feeding channel 32 after adjustment remains unchanged, and avoiding the pin shaft from offsetting during the feeding process.

[0032] As a preferred solution of the present invention, the transmission structure includes a transmission shaft 36 arranged above the pin shaft feeding mechanism 3, and the two ends of the transmission shaft 36 are respectively connected to the two adjusting screws 34 through transmission belts 37. The transmission shaft 36 and the adjusting screw 34 are both provided with transmission wheels that cooperate with the transmission belts 37.

[0033] As a preferred solution of the present invention, in order to achieve rapid disassembly and assembly of the positioning head 42, the positioning seat 41 is magnetically connected to the positioning head 42, and the positioning seat 41 is provided with a groove 44 that cooperates with the positioning head 42, and the bottom of the groove 44 is provided with a support platform 45, and the support platform 45 is provided with an avoidance groove, which is provided to prevent the support platform 45 from colliding with the pin shaft.

[0034] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
