[0033] Reference Figures 1-5 A big axle power terminal crimping machine wire feeder, including base 1, the vertical plate 2 symmetrically arranged at the both sides of base 1, still include:
[0034] Power device: including driving shaft 3, driven shaft 4 and two reinforcing shafts 5 installed in parallel between two vertical plates 2, the driving shaft 3 both ends are rotatably connected with vertical plate 2 through bearing, and one end is driven by motor 7 through speed reducer 6, the driving shaft 3 and driven shaft 4 are all coaxially installed with antiskid rubber cylinder 8, the antiskid rubber cylinder 8 both ends are detachably installed with limit disc 9, its diameter is greater than the diameter of antiskid rubber cylinder 8, it can be fixed by screw, bolt etc.;Antiskid rubber cylinder 8 can increase friction, facilitate driving wire coil 18 synchronous rotation, also can prevent the damage of electric wire 19 surface;Limit disc 9 can limit the activity range of wire coil 18, avoids arbitrary movement.
[0035] Buffer device: including vertical column 10 fixedly on base 1, sliding groove 11 along the height direction of vertical column 10 is set, and pulley assembly 12 is installed in sliding groove 11;The pulley assembly 12 includes sliding wheel 121, outer frame 122 located at the periphery of sliding wheel 121, wheel shaft 123 connecting outer frame 122 and sliding wheel 121, one end of wheel shaft 123 is slidably connected with sliding groove 11 through sliding block 124, and positioning member 20 is threadedly connected at the top of sliding groove 11, to prevent sliding wheel 121 from moving out from the top of sliding groove 11;Wire guide shaft 16 is also installed on the vertical column 10 at the same side of sliding groove 11, and protective frame 17 with two open ends is installed on the periphery of wire guide shaft 16;When using, one end of electric wire 19 is wound on wire coil 18, and the other end is wound from the upper end outer wall of wire guide shaft 16, and then is wound from the lower end outer wall of sliding wheel 121 again;When the wire processing equipment drags one end of electric wire 19, motor 7, speed reducer 6, driving shaft 3 and wire coil 18 rotate synchronously, and sliding wheel 121 slides linearly upwards along sliding groove 11 under the action of the upward force of electric wire 19;When the wire processing equipment stops dragging, motor 7 stops rotating, and sliding wheel 121 slides linearly downwards along sliding groove 11 under the action of gravity, which can play the role of buffering and preventing electric wire 19 from winding.
[0036] Adjustment and reinforcement structure: two upright plates 2 are symmetrically provided with arc-shaped adjustment grooves 13, and the driven shaft 4 is detachably clamped in the adjustment grooves 13; two reinforcing shafts 5 are arranged outside the driving shaft 3 and the driven shaft 4, and the height from the ground is higher than that of the driving shaft 3 and the driven shaft 4; the two reinforcing shafts 5 are used to improve the strength and structural stability of the two upright plates 2, and also prevent the wire coil 18 from sliding out of the two ends.
[0037] The above structure solves the problems of insufficient device power transmission stability and easy deviation of the wire coil 18. Through parallel arrangement of the driving shaft, the driven shaft and the reinforcing shaft, combined with the anti-skid rubber cylinder and the limiting disc, the transmission friction is enhanced and the displacement of the wire coil 18 is limited; the buffer device slides in the sliding groove through the pulley assembly, which can offset the vibration of the device; the adjustment groove supports flexible adjustment of the position of the driven shaft, which is suitable for different wire diameters. The self-weight of the wire coil 18 in the present application is about 5-15 kg, even if the wire wound on the wire coil 18 is less and almost complete, it can also be driven to rotate by the driving shaft under its own gravity. The large shaft refers to the driving shaft and the driven shaft, and the diameter of the two is 50-10 cm, which can withstand a larger weight.
[0038] In some embodiments, the outer frame 122 includes two parallel frame plates 1221, and the frame plates 1221 are connected at both ends by connecting rods 1222. The outer circle of the sliding wheel 121 is provided with a V-shaped annular groove 1211, and the wheel shaft 123 penetrates the center of the sliding wheel 121 and the frame plate 1221. The above structure optimizes the guiding accuracy and durability of the pulley assembly. The outer frame is a rigid structure composed of frame plates and connecting rods, which prevents deformation and prevents the wire 19 from sliding out; the V-shaped annular groove of the sliding wheel precisely constrains the cable path, and the wheel shaft penetration design ensures that the sliding wheel and the outer frame move synchronously, reducing wear and tear.
[0039] In some embodiments, the bottom of the base 1 is provided with at least four moving wheels 14 and height adjustment fixing feet 15, and the moving wheels 14 and the fixing feet 15 are alternately distributed. The above structure balances the convenience of device movement and the stability of operation. The alternately distributed moving wheels and fixing feet on the bottom of the base realize quick displacement and fixed locking, avoiding device sliding during crimping.
[0040] In some embodiments, the height of the driving shaft 3 from the ground is less than the height of the driven shaft 4 from the ground, and the area between the driving shaft 3 and the driven shaft 4 forms a wire coil 18 accommodating space. The above structure solves the problems of insufficient wire coil 18 storage space and tension control. The low position of the driving shaft and the high position of the driven shaft form a slope-shaped accommodating space, which utilizes the height difference to make the wire coil 18 naturally fall, maintains the uniformity of the wire release tension, and reduces the risk of wire jamming.
[0041] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present application. Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made thereto without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
