The spring loading mechanism 5 comprises a spring feeding vibration plate 51, a spring carrying assembly 52, a spring steering positioning assembly 53, a spring loading assembly 54 and a mandril driving assembly 55.
Wherein, dress spring assembly 54 for the spring installation position 16 of the compression spring 16 in the realization is packed into tool subassembly 22 specifically includes: a driving connecting plate 5405, a spring jig plate 5409, and a longitudinal pushing driving structure 5419 (specifically, an air cylinder, a motor or other driving member, etc.); the driving connecting plates 5405 and the spring jig plates 5409 are arranged in an up-down parallel manner at intervals and are connected in a relative motion manner. Two groups of spring channels which are arranged in a left-right symmetry manner are formed on the spring jig plate 5409; each set of spring channels includes a transverse spring channel 5416 and a longitudinal spring channel 5417, a spring slot 5418 is formed in the transverse spring channel 5416, and one side end of the transverse spring channel 5416 is communicated with the top end of the longitudinal spring channel 5417.

Under the driving of the longitudinal pushing driving structure 5419, the driving connecting plate 5405 and the spring jig plate 5409 can synchronously move downwards for a first distance, and the driving connecting plate 5405 moves downwards for a second distance independently until the longitudinal pushing piece 5412 moves downwards along the longitudinal spring channel 5417 to press the spring piece 15 out to the spring mounting position 16 in the jig component 22 below.
It will be appreciated that since the embodiment of the invention is described only in terms of the product 1 shown in fig. 2, which product 1 requires the assembly of two spring elements 15, the spring assembly 54 is provided with two sets of spring channels for efficiency, to achieve automatic assembly of two spring elements 15 simultaneously. In fact, when the number of spring elements 15 to be assembled varies, a matching with the current product can be achieved by a simple adjustment of the number of passages. The invention is not limited in this regard.
The spring steering positioning component 53 is used for realizing steering positioning of the spring element 15, and specifically comprises: a positioning support plate 5310, an inner bore gradual change cam plate 5304, and a steering motor 5302. A positioning support plate 5310 provided with longitudinal grooves and transverse grooves arranged crosswise; two positioning sliders 5306 which are connected through a third compression spring 5309 in a relative motion mode are arranged in the inner hole of the inner hole gradual change cam plate 5304, a positioning block 5308 is arranged at the top of each positioning slider 5306, and the two positioning blocks 5308 are symmetrically arranged along the length direction of the longitudinal groove; the steering motor 5302 is in driving connection with the two positioning sliders 5306 through a positioning shaft 5305; during the process that the steering motor 5302 drives the positioning shaft 5305 to rotate, the two positioning blocks 5308 are driven to move relatively along the longitudinal groove to be in an opening state or a clamping state. When the two positioning blocks 5308 are opened, the spring piece 15 can be smoothly placed into the longitudinal groove of the positioning support plate 5310 by the longitudinal finger clamping cylinder 525; after the positioning block 5308 clamps, the longitudinal position of the spring element 15 in the longitudinal groove of the support plate 5310 can be ensured to be consistent, and the space of the longitudinal groove after the positioning block 5308 clamps is approximately equal to the initial length of the spring element 15, so that a large error of the longitudinal position after the spring element 15 is discharged and turned can be avoided.
The detailed working flow of the spring loading mechanism 5 is as follows:
1) spring piece 15 is conveyed to a straight vibrating left channel 513 and a straight vibrating right channel 514 through circular vibrating track screening orientation, then a transverse moving cylinder 522 and a lifting cylinder 524 are used for moving a longitudinal clamping finger cylinder 525 to a discharge hole of the straight vibrating right channel 514, synchronously, a spring carrying assembly 52 arranged in a mirror image mode can move the other longitudinal clamping finger cylinder 525 to a discharge hole of the straight vibrating left channel 513, and meanwhile, two longitudinal spring pieces 15 are taken and placed on a positioning support plate 5310 of a spring steering positioning assembly 53.
2) As shown in fig. 10 and 11, the spring turning positioning assembly 53 is in an initial state, the third compression spring 5309 pushes the two positioning sliders 5306 open until the bearing 5307 abuts against the inner hole of the inner hole gradual change cam plate 5304, at this time, the two positioning blocks 5308 are in an open state, the distance between the two positioning blocks 5308 is greater than the length of the spring element 15, so that the spring element 15 can be smoothly placed into the longitudinal groove of the positioning support plate 5310, the turning motor 5302 drives the turning positioning shaft 5305 to rotate by 90 °, the gradual change hole with the diameter being greatly reduced of the inner hole gradual change cam plate 5304 moves the pressing bearing 5307 toward the spring element 15 during the rotation process, and after the 90 ° rotation is completed, the two positioning blocks 5308 are in a clamping state, the distance between the two positioning blocks is equal to or slightly greater than the length of the spring element 15, so that the 90 ° turning in the angular direction of the spring element 15 and the positioning in the longitudinal direction of the spring element are completed.
