The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:
examples
As shown in fig. 1 to 3, the present embodiment provides a socket protective door spring assembling mechanism for assembling a spring 1 to a protective door 1 and a socket panel 3, so as to realize automatic reset of the protective door 1. Before assembly, the protective door 1 is arranged on the inner side of the socket panel 3 in a sliding mode, and a spring assembly gap 4 is reserved between the protective door 1 and the socket panel 3.
The assembling mechanism comprises a spring seat 5, and a push rod 6 and a press rod 7 which are inserted into the spring seat 5 in a sliding manner, wherein the spring seat 5 is correspondingly provided with a push rod slideway 51 and a press rod slideway 52, the push rod 6 and the press rod 7 can slide back and forth in the push rod slideway 51 and the press rod slideway 52, and specifically, the cooperation of the push rod 6 and the press rod 7 with the push rod slideway 51 and the press rod slideway 52 is clearance fit.
Meanwhile, the push rod slide way 51 and the press rod slide way 52 are intersected at the assembly outlet 53, wherein the press rod slide way 52 is vertically opposite to the assembly outlet 53, and the included angle between the push rod slide way 51 and the press rod slide way 52 is 45 degrees. Usually, the included angle between the two slide ways is required to be kept to be less than 90 degrees, and the included angle between the push rod slide way 51 and the press rod slide way 52 can be determined to be other angles on the basis of practical application.
Specifically, the spring 1 is slidably disposed in the push rod slide way 51 and pushed by the push rod 6, wherein the maximum outer diameter of the spring 1 is smaller than the minimum inner diameter of the push rod slide way 51, so as to avoid the pushing difficulty.
In this embodiment, the push rod 6 and the press rod 7 are both rectangular rods, so as to effectively avoid rotation. In addition, because the pushing route of the push rod slideway 51 is a side edge, one end of the push rod 6 for pushing the spring 1 is an inclined surface, and the contact area can be increased by the pushing end surface of the inclined surface. Meanwhile, the pushing route of the pressure lever slide way 52 is a right opposite side, so that one end of the pressure lever 7 pushing the spring 1 is a plane, and the pushing end surface of the plane has the largest contact area.
In addition, the mechanism further comprises a feeding block 8 used for feeding the spring 1, the feeding block 8 is movably arranged and tightly attached to an inlet of the push rod slide way 51, and the feeding block 8 is used for conveying the spring 1 to the position of the push rod slide way 51 of the spring seat 5, so that the push rod 6 can conveniently push the spring 1 along the push rod slide way 51. Specifically, as shown in fig. 3, the loading block 8 is provided with a spring 1 fixing through hole corresponding to the size of the push rod slideway 51, and during pushing, the push rod 6 penetrates through the spring 1 fixing through hole of the loading block 8 to push the spring 1 into the spring seat 5.
In addition, the assembly outlet 53 of the spring seat 5 is aligned with the spring assembly gap 4 and is installed, and for quick positioning, a positioning hook 54 is arranged outside the assembly outlet 53, and the positioning hook 54 is clamped on the side wall of the spring assembly gap 4 during positioning. The assembly length of the spring 1 assembly gap 4 in the sliding direction of the protective door 1 is smaller than the original length of the spring 1, so that the spring 1 is always kept in a compressed state and is convenient for elastic reset.
During the assembly, set up shutter 1 slip in socket panel 3 inboard earlier, spring 1 assembly clearance 4 keeps the maximum distance between shutter 1 and the socket panel 3, at this moment, aligns and laminates spring assembly clearance 4 with the assembly export 53 of spring holder 5, and the location colludes 54 joint and fixes a position in the lateral wall of spring assembly clearance 4. The material loading block 8 conveys the spring 1 to the inlet position of the push rod slide way 51 of the spring seat 5, the push rod 6 penetrates through the spring 1 fixing through hole of the material loading block 8 to push the spring 1 into the spring seat 5, and then the push rod 6 pushes the spring 1 to the assembly outlet 53 along the push rod slide way 51, so that one end of the spring 1 is abutted to the spring assembly gap 4, and the spring 1 is preliminarily compressed. Then, the pressing rod 7 is pushed, the pressing rod 7 presses the side surface of the spring 1 from the front surface, the spring 1 is completely pressed into the spring assembling gap 4, and the spring 1 is always kept in a compressed state in the spring assembling gap 4, so that the assembling of the spring 1 is completed. The assembly mechanism is convenient to operate, simple and rapid, the motion of the spring seat 5, the push rod 6 and the press rod 7 can be automatically operated by using control equipment such as cylinders and a PLC control system, and the production efficiency is improved.
