A shift spring block 9 is longitudinally arranged, which is slidably fitted on the vertical plate 2. A vertical groove connected to the feed channel 5 is opened at the upper end of the shift spring block 9. The spring dropped from the feed channel enters the vertical groove and a part of it extends out of the vertical groove. The lower end of the shift spring block 9 is connected to a longitudinal moving member 12 driven by a second motor 10. The second motor is a servo motor. A clamping assembly 13 located below the elastic telescopic column 8 is arranged at the bending part of the slideway 6. A compression spring assembly 14 connected to the longitudinal moving member 12 is arranged at the vertical plate 2. The longitudinal moving member 12 drives the shift spring block 9 to move forward to the bottom of the elastic telescopic column 8, and the spring in the vertical groove is sleeved by the elastic telescopic column 8. At the same time, the longitudinal moving member 12 drives the clamping assembly 13 to release, and then the longitudinal moving member 12 moves backward. The longitudinal moving member 12 drives the clamping assembly 13 to reset to clamp the oil seal. The longitudinal moving member 12 drives the elastic telescopic column 8 to elastically press the oil seal downward through the compression spring assembly 14. The spring on the elastic telescopic column 8 is pressed into the oil seal, and the elastic telescopic column 8 rises and resets.The oil seal at the slide is continuously transported through the vibrating plate, and the spring is poured into the hopper. The first motor drives the turntable to rotate counterclockwise, and the spring is magnetically attracted to the turntable and transferred into the feed channel one by one (the feed channel only allows one spring to pass through). The springs in the feed channel are arranged in sequence, and the spring at the bottom of the feed channel enters the vertical slot and a part of it extends out of the vertical slot. The second motor drives the longitudinal moving part forward, and the longitudinal moving part moves forward with the moving spring block to the bottom of the elastic telescopic column. The spring in the vertical slot is sleeved by the elastic telescopic column, and the inner column of the elastic telescopic column first hooks the extended spring, and then drags out the spring in the vertical slot. The spring is sleeved on the bottom of the inner column of the elastic telescopic column, and the distance between the elastic telescopic column and the moving spring block is smaller than the distance between the spring and the moving spring block. The thickness of the oil seal is measured by the cylinder. At the same time, the longitudinal moving part drives the clamping release assembly to loosen, and the cylinder drives the push bar to move the oil seal at the front of the slide to the left to replace the loosened oil seal. The push bar is reset and the subsequent oil seal is filled (when the push bar moves to the left, the baffle bar is pushed open accordingly, and after the push bar is reset, the baffle bar is twisted and reset). Then the longitudinal moving part moves backward and resets with the moving spring part, and the spring at the bottom of the feed channel falls into the vertical groove. The longitudinal moving part drives the clamping release assembly to reset, and the clamping release assembly clamps the oil seal. The longitudinal moving part drives the elastic telescopic column to elastically press the oil seal downward through the compression spring assembly. The inner column of the elastic telescopic column contacts the diameter of the oil seal and shrinks upward. The outer column of the elastic telescopic column presses the spring sleeved on the inner column into the diameter of the oil seal, and then the elastic telescopic column rises and resets.

[0032] The vertical plate 2 is vertically provided with movable grooves 2.1 located on the left and right sides of the feed channel 5, and the lower end of the vertical plate 2 is provided with an escape groove 2.2 for avoiding the oil seal. The movable groove can accommodate the seesaw movement of the compression spring assembly, and the escape groove can avoid the oil seal coming down from the slideway.

[0033] The second motor 10 is arranged at the upper end of the base 1, and a driving gear 11 is keyed to the output shaft of the second motor 10, and the driving gear 11 is meshed with the first rack 12.2. The second motor drives the driving gear to rotate, and the driving gear drives the longitudinal moving member to move forward and backward through the first rack.

[0034] See also Fig.11 , Fig.14 The longitudinal moving member 12 comprises a strip 12.1 connected to the lower end of the shifting spring block 9, a first rack 12.2 is longitudinally arranged at the bottom of the strip 12.1, a bending portion 12.3 is connected to the left side of the front end of the strip 12.1, a second rack 12.4 is arranged on the right side of the bending portion 12.3, a convex portion 12.4 is arranged at the rear end of the strip 12.1, and a one-way limiting groove 12.5 is arranged at the upper end of the convex portion 12.4. The strip drives the shifting spring block to move forward and backward, the second rack drives the loosening assembly to loosen through the lower gear of the loosening assembly, and the one-way limiting groove allows the lifting block of the compression spring assembly to be twisted, and the lifting block can only be tilted counterclockwise.

[0035] See also Fig.12 , Fig.13The clamping assembly 13 includes a stabilizing plate 13.1 connected to the slideway 6, and the stabilizing plate 13.1 is symmetrically provided with clamps 13.2 along the axis of the elastic telescopic column 8. The two clamps 12.3 are slidably fitted on the stabilizing plate 13.1 so as to move forward and backward. An upper gear 13.3 connected coaxially and a lower gear 13.4 matched with the second rack 12.4 are rotatably provided below the stabilizing plate 13.1. The clamping member 13.2 includes a middle connecting strip 13.2.2 connecting the inner clamping block 13.2.1 and the outer sliding rod 13.2.4. The sliding rod 13.2.4 is longitudinally penetrated in the stabilizing plate 13.1.

The lower end of the connecting strip 13.2.2 is longitudinally provided with a third rack 13.2.3 meshing with the upper gear 13.3. The inner side of the clamping block is provided with an arc surface, and a rubber pad can be provided on the arc surface. When the longitudinal moving part moves forward, the second rack of the longitudinal moving part meshes with the lower gear, and the lower gear drives the two third racks to move the clamping block outward along the direction of the slide rod through the upper gear. The clamping block loosens the oil seal, and the cylinder drives the push bar to move left, pushing the oil seal at the front side of the slide to the left below the elastic telescopic column (the loosened oil seal is pushed down), and then the longitudinal moving part moves backward and resets, and the second rack of the longitudinal moving part reverses the lower gear, and the two third racks move the clamping block inward and reset along the direction of the slide rod. When the clamping block is reset, the second rack disengages from the lower gear, and the clamping block clamps the oil seal under the action of the first elastic member.

[0036] The compression spring assembly 14 includes a lifting block 14.1 twisted in the one-way limit groove 12.5, a torsion spring is connected between the lifting block and the one-way limit groove, and ears 14.4 are symmetrically arranged on the left and right sides of the rear end of the vertical plate 2, a rotating shaft is connected between the two ears 14.4, and two lifting rods 14.3 with guide grooves are rotatably arranged on the rotating shaft, a connecting rod 14.2 lifted by the rearward-moving lifting block 14.1 is connected between the two lifting rods 14.3, and a sliding column 14.5 slidably fitted in the guide groove is transversely arranged on the upper end of the elastic telescopic column 8. When the longitudinal moving part moves forward, the one-way limit groove of the longitudinal moving part moves forward with the lifting block, and the lifting block is pressed down counterclockwise by the connecting rod and retracted into the one-way limit groove to pass through the connecting rod. After the elastic telescopic column is covered with a spring and the loose clamp assembly clamps the new oil seal, the longitudinal moving part moves backward and resets, and the one-way limit groove moves backward with the lifting block, and the lifting block contacts the connecting rod and lifts the connecting rod and the tilting rod, and the tilting rod drives the elastic telescopic column to vertically descend through the sliding column. The elastic telescopic column elastically presses down the oil seal, so that the spring on the elastic telescopic column is pressed into the oil seal, and then the lifting block detaches from the connecting rod, and the connecting rod, the tilting rod and the elastic telescopic column are reset under the action of the second elastic part.

[0037] The left side of the upper end of the lifting block 14.1 is provided with an inclined surface for lifting the connecting rod 14.2, and the right end surface of the lifting block 14.1 is vertically against the right side wall of the one-way limit groove 12.5. When the lifting block moves backward, the inclined surface contacts and lifts the connecting rod, and the lifting block is held by the right side wall of the one-way limit groove. When the lifting block moves forward, the lifting block contacts the connecting rod and falls.

[0038] The front end of the vertical plate 2 is provided with a mounting block 15, and a stopper 16 located on the right side of the feed channel 5 is vertically arranged on the mounting block 15. The spacing between the stopper and the rotating disk can only allow one spring to pass through, so as to prevent the spring from blocking the feed channel after being stacked.

[0039] The specific working process of the present invention is as follows: the oil seal at the slide is continuously transported through the vibrating plate, the spring is poured into the hopper and slides to the turntable, the first motor drives the turntable to rotate counterclockwise, the springs are magnetically attracted to the turntable and rotated into the feed channel one by one (the feed channel can only allow one spring to pass), the springs in the feed channel are arranged in sequence, the spring at the bottom of the feed channel enters the vertical slot and a part of it extends out of the vertical slot, such as Figure 7 As shown, the second motor drives the longitudinal moving member to move forward, and the long strip of the longitudinal moving member moves the moving spring block forward to the bottom of the elastic telescopic column. The spring in the vertical groove is sleeved by the elastic telescopic column, and at the same time, the second rack of the longitudinal moving member engages with the lower gear, and the lower gear drives the two third racks to move the clamping block outward along the direction of the slide rod through the upper gear. The clamping block releases the oil seal, and the one-way limit groove of the longitudinal moving member moves the lifting block forward. The lifting block is pressed down counterclockwise by the connecting rod and retracts into the one-way limit groove to pass through the connecting rod. Figure 8 , 9 As shown, the cylinder drives the push bar to move left, pushing the oil seal at the front side of the slide to the left to the bottom of the elastic telescopic column (the loosened oil seal is pushed down), the push bar blocks the subsequent oil seal, and then the push bar moves right to reset, and the subsequent oil seals of the slide are supplemented, and then the longitudinal moving part moves backward with the shifting spring block to reset, and the spring at the bottom of the feed channel falls into the vertical groove, and the second rack of the longitudinal moving part reverses the lower gear, and the two third racks move the clamping block inward along the direction of the slide rod to reset, and when the clamping block resets, the second rack disengages from the lower gear, and the clamping block clamps the oil seal under the action of the first elastic member, and the one-way limit groove moves the lifting block backward, and the lifting block contacts the connecting rod and lifts the connecting rod and the tilting rod, and the tilting rod drives the elastic telescopic column to vertically descend through the sliding column, and the elastic telescopic column elastically presses down the oil seal, so that the spring on the elastic telescopic column is pressed into the oil seal, as shown in FIG. Fig.10 As shown, the lifting block is then separated from the connecting rod, and the connecting rod, the tilting rod, and the elastic telescopic column are reset under the action of the second elastic member, and the lower limit ring is against the flat plate.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
