With reference to fig. 1 to 5, the utility model discloses a tulip contact assembling device for the installation and processing of tulip contact 10. As shown in fig. 1, a schematic diagram of a tulip contact 10 is shown, which includes a plurality of contact blades 11 arranged in a circumferential array, and a ring-shaped spring engaged in a groove on an outer side of the contact blade 11, when the tulip contact 10 is installed, the contact blade 11 is installed first, and then the ring-shaped spring is engaged to upper and lower ends of the contact blade 11. The tulip contact mounting device of the present application is used to mount the spring to the contact plate 11. In order to simplify the drawing, the ring springs in the present embodiment are simply illustrated by lines.

Cooperation fig. 2 to fig. 5 show, a plum blossom contact assembly quality, including support frame 20 and guide holder 30, be equipped with unable adjustment base 21, promotion structure 22 on the support frame 20 and drive promotion structure 22 up-and-down motion's driving piece 23, unable adjustment base 21 is equipped with the fixed slot 211 that the plum blossom contact 10 was placed in the matching, promotion structure 22 includes a plurality of ejector pads 221 that evenly arrange along a circumferencial direction, just promotion structure 22 is located unable adjustment base 21's top, guide holder 30 is the round platform form, and it includes major diameter end 31 and path end 32, the diameter of path end 32 is not more than a plurality of ejector pads 221 and encloses the diameter that closes and form the circumference, the diameter of major diameter end 31 is not less than the external diameter of plum blossom contact 10.

By using the mounting device, one end of the tulip contact 10 with the contact piece 11 assembled is placed and fixed in the fixing groove 211, then the large-diameter end 31 of the guide seat 30 is placed on the other end of the tulip contact 10 in a matching manner, the annular spring to be mounted is sleeved on the small-diameter end 32 of the guide seat 30, the driving piece 23 drives the pushing block 221 to move downwards, the pushing block 221 pushes the annular spring downwards along the guide seat 30 until the annular spring is clamped into the groove of the contact piece 11 of the tulip contact 10, and thus the mounting of the annular spring at one end of the tulip contact 10 is completed. And then the guide seat 30 is taken down, the tulip contact 10 is turned over by 180 degrees, namely the top end and the bottom end are interchanged, and the operation is repeated to complete the installation of the spring at the other end of the contact which is not exchanged.

The number of the push blocks 221 is four, and the four push blocks 221 are arranged in a circumferential array, so that the annular spring is pushed downwards to be stressed uniformly. When the annular spring is engaged with the small-diameter end 32 of the guide seat 30, the bottom end of the pushing block 221 exactly corresponds to the annular spring, so that the annular spring can be exactly pushed down when the pushing block 221 moves downwards.

The pushing structure 22 further includes a connecting seat 222 and a connecting crank arm 223 corresponding to the pushing block 221 one by one, the driving member 23 is a vertically arranged cylinder, and the connecting seat 222 is connected to the bottom end of the piston rod of the cylinder. The top end of the pushing block 221 is rotatably connected to the connecting base 222, the pushing block 221 is provided with a sliding slot 2211 arranged longitudinally, a sliding block 2212 in sliding fit with the sliding slot 2211 is arranged in the sliding slot 2211, one end of the connecting crank arm 223 is rotatably connected to the sliding block 2212, and the other end of the connecting crank arm 223 is rotatably connected to the connecting base 222. Specifically, the connecting crank arm 223 is rotatably connected to the bottom surface of the connecting seat 222, and extends from the inner side surface of the push block 221 into the push block 221 to be rotatably connected to the slider 2212. The pushing block 221 can rotate with the connection point of the pushing block 221 and the connecting seat 222 as a rotation point, and in this process, the sliding block 2212 slides up and down along the sliding groove 2211.

An annular return spring 224 is sleeved along the outer side surface of the plurality of pushing blocks 221, and a positioning notch 2213 for positioning the return spring 224 is arranged on the outer side surface of the pushing block 221.

The driving member 23 drives the pushing block 221 to move downward, and the pushing block 221 correspondingly drives the annular spring to move downward along the guide seat 30. The outer diameter of the guide seat 30 gradually increases, and in this process, the connection point of the push block 221 and the connection seat 222 is used as a rotation point, the push block 221 rotates towards the outside, and the return spring 224 is stretched and expanded until the push block 221 pushes the annular spring into the groove on the outer side of the contact piece 11 of the tulip contact 10. Then, the driving member 23 drives the pushing block 221 to move upward for resetting, in this process, the pushing block 221 rotates inward by using the connection point of the pushing block 221 and the connecting seat 222 as a rotation point under the restoring force of the restoring spring 224 until the pushing block 221 resets.

The middle part of the fixing groove 211 is provided with a positioning column 212 which is vertically arranged, and the large-diameter end 31 of the guide holder 30 is provided with a positioning hole 312 which is matched with the positioning column 212. The positioning posts 212 and the positioning holes 312 are designed to facilitate the rapid and accurate placement of the guide base 30. When the tulip contact 10 is placed on the fixing base 21, the positioning column 212 correspondingly penetrates through the middle of the tulip contact 10.

The small diameter end 32 of the guide seat 30 is provided with an extending portion 321 extending along the axial direction thereof, and the extending portion 321 is cylindrical. The extension 321 facilitates better pre-nesting of the ring spring to be installed. The large diameter end 31 of the guide seat 30 is provided with a slot 311 which can be matched and clamped with the tulip contact 10. When the guide holder 30 is placed, the clamping groove 311 of the large-diameter end 31 is correspondingly clamped with the tulip contact 10, and meanwhile, the positioning hole 312 at the bottom end of the positioning groove is correspondingly matched with the positioning column 212, so that the guide holder 30 is placed and fixed quickly, accurately and stably, and the subsequent installation of the annular spring is facilitated. Wherein, the guide seat 30 is designed as a hollow structure, and the small diameter end 32 is not closed, so that the guide seat 30 is more portable and convenient to use.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
