Description

Technical Field

[0001] The invention belongs to the technical field of industrial automation, and in particular relates to an automatic continuous spring feeding device for a spring grinding machine. Background Art

[0002] Since the Industrial Revolution, springs, as fundamental elastic energy storage components, have been widely used in machinery, transportation, electronics, aerospace, and other fields. They perform key functions such as cushioning and shock absorption, energy storage, force transmission, and motion control. A few years ago, the spring processing industry had only a few spring machines. With the continuous development of the spring market, specialized spring processing equipment has gradually been used. The main types of spring processing machines currently in use include spring torsion machines, spring grinding machines, and spring straightening machines.

[0003] At present, most spring grinding machines are not equipped with automatic feeding devices. Workers are required to manually sort out the springs one by one and place them in the relative workstations of the spring grinding machine. This loading method has low production efficiency and consumes manpower. When working for a long time, workers are prone to fatigue and distraction, which may lead to production accidents during operation. Summary of the Invention

The second spring hole is arranged vertically and passes through from top to bottom; an upper positioning hole corresponding to the position of the second spring hole is opened on the base; The material receiving box and the horizontal pushing mechanism are both arranged in the base, one side of the material receiving box is connected to the driving end of the horizontal pushing mechanism, and the driving end of the horizontal pushing mechanism drives the material receiving box to move between the loading station and the unloading station; a vertical third spring hole is opened in the material receiving box, and the third spring hole passes through from top to bottom.

[0006] According to the above scheme, the horizontal pushing mechanism includes a first cylinder and a horizontal push rod both arranged in the base; the output end of the first cylinder is connected to one end of the horizontal push rod, and the other end of the horizontal push rod is connected to one side of the material receiving box.

[0007] According to the above solution, a fixed guide rail is provided at the bottom inner side of the base, and a guide groove adapted to the outer peripheral surface of the horizontal push rod is opened on the fixed guide rail; the horizontal push rod moves along the guide groove on the fixed guide rail.

[0008] According to the above solution, a chute adapted to the bottom of the material receiving box is provided at the inner bottom of the base; and the lower positioning hole is provided at the bottom of one side of the chute.

[0009] According to the above scheme, the feeding assembly is also provided with a vertical pushing mechanism; the vertical pushing mechanism includes a vertically arranged second cylinder and a vertical push rod; the second cylinder is connected to the outer wall of the feeding box; the driving end of the second cylinder is connected to the upper end of the vertical push rod, and the lower end of the vertical push rod can pass through the top of the base and be inserted into the third spring hole of the receiving box located at the unloading station.

[0010] According to the above scheme, the base includes a seat plate and a seat cover arranged on the seat plate; the material receiving box and the horizontal pushing mechanism are both arranged on the seat plate; the slide groove and the lower positioning hole are both opened on the seat plate, and the groove walls on both sides of the slide groove are used to limit the material receiving box, so that when the material receiving box moves to the groove walls on both sides, it is just at the loading position or the unloading position; the loading box is arranged on the seat cover, and the seat cover is provided with an upper positioning hole.

[0011] According to the above scheme, the grinding wheel assembly includes a rotating shaft and a turntable; the lower end of the rotating shaft is rotatably connected to the workbench; the turntable is arranged on the workbench, and the rotating shaft passes through the center of the turntable; the first spring holes are evenly spaced circumferentially on the turntable.

[0012] According to the above scheme, N first spring holes can be set in the same radial direction on the turntable, N second spring holes are correspondingly set on the feeding box, and N third spring holes are correspondingly set on the receiving box. The N third spring holes all correspond one-to-one to the N first spring holes in the same radial direction located on the receiving station.

[0013] According to the above solution, the base is connected to the frame via a fixed shaft.

The second spring hole 16 is arranged vertically and passes through from top to bottom; an upper positioning hole corresponding to the position of the second spring hole 16 is opened on the base; The material receiving box 8 and the horizontal pushing mechanism are both arranged in the base. One side of the material receiving box 8 is connected to the driving end of the horizontal pushing mechanism. The driving end of the horizontal pushing mechanism drives the material receiving box 8 to move between the loading station and the unloading station. A vertical third spring hole 17 is opened in the material receiving box 8, and the third spring hole 17 is passed through from top to bottom. When the material receiving box 8 is at the loading position, the upper end of the third spring hole 17 is directly opposite to the lower end of the second spring hole 16; When the material receiving box 8 is at the unloading position, the lower end of the third spring hole 17 is directly opposite to the upper end of the first spring hole 20 .

[0032] In the present invention, the spring workpiece 15 is loaded into the second spring hole 16 in the loading box 6. When the horizontal pushing mechanism pushes the receiving box 8 from the unloading station to the loading station, the spring workpiece 15 in the loading box 6 passes through the upper positioning hole of the base and falls into the third spring hole 17 of the receiving box 8; when the horizontal pushing mechanism pushes the receiving box 8 from the loading station to the unloading station, the spring workpiece 15 in the receiving box 8 passes through the lower positioning hole 10 of the base and falls into the first spring hole 20 on the grinding disc assembly. The apertures of the upper positioning hole and the lower positioning hole 10 are not less than the apertures of each spring hole; the reciprocating motion of the horizontal pushing mechanism causes the receiving box 8 to switch back and forth between the loading station and the unloading station, thereby realizing continuous loading of the spring workpiece 15.

[0033] In the present invention, the length of the third spring hole 17 is consistent with the length of the spring workpiece 15 to ensure that each time a spring workpiece 15 falls into the third spring hole 17, the horizontal pushing mechanism pushes the receiving box 8 from the loading station to the unloading station for unloading.

[0036] In the present invention, there are two horizontal push rods 5, which are arranged side by side and are both driven by the first cylinder 4; the piston rod of the first cylinder 4 drives the horizontal push rod 5 to reciprocate, and then drives the material receiving box 8 to switch back and forth between the loading station and the unloading station.

[0037] Preferably, a fixed guide rail 11 is provided at the bottom inner portion of the base, and a guide groove adapted to the outer circumference of the horizontal push rod 5 is provided on the fixed guide rail 11 ; the horizontal push rod 5 moves along the guide groove on the fixed guide rail 11 .

[0038] Preferably, a chute 18 adapted to the bottom of the receiving box 8 is provided at the bottom of the base; and the lower positioning hole 10 is provided at the bottom of one side of the chute 18 .

[0039] In the present invention, the material receiving box 8 moves horizontally along the slide groove 18 in the base, thereby improving the accuracy of the translation of the material receiving box 8.

[0040] Preferably, the feeding assembly 1 is also provided with a vertical pushing mechanism; the vertical pushing mechanism includes a vertically arranged second cylinder 12 and a vertical push rod 9; the second cylinder 12 is connected to the outer wall of the feeding box 6; the driving end of the second cylinder 12 is connected to the upper end of the vertical push rod 9, and the lower end of the vertical push rod 9 can pass through the top of the base and be inserted into the third spring hole 17 of the receiving box 8 located at the unloading station.

[0041] In the present invention, when the spring workpiece 15 is stuck in the third spring hole 17 of the material receiving box 8 and cannot fall into the first spring hole 20 of the grinding disc assembly by itself, the vertical pushing mechanism is started, and the second cylinder 12 is used to drive the vertical push rod 9 to move vertically downward to push the spring workpiece 15 in the third spring hole 17 into the first spring hole 20.

[0042] Preferably, the base includes a seat plate 14 and a seat cover 2 provided on the seat plate 14; the material receiving box 8 and the horizontal pushing mechanism are both provided on the seat plate 14; the slide groove 18 and the lower positioning hole 10 are both opened on the seat plate 14, and the groove walls on both sides of the slide groove 18 are used to limit the material receiving box 8, so that the material receiving box 8 is just at the loading position or the unloading position when it moves to the groove walls on both sides; the loading box 6 is provided on the seat cover 2, and the seat cover 2 is provided with an upper positioning hole corresponding to the second spring hole position 16 (not shown in the drawing).

[0043] Preferably, the grinding wheel assembly includes a rotating shaft 19 and a turntable 3; the lower end of the rotating shaft 19 is rotatably connected to the workbench 13; the turntable 3 is arranged on the workbench 13, and the rotating shaft 19 passes through the center of the turntable 3; the first spring holes 20 are evenly spaced circumferentially on the turntable 3.

[0044] In the present invention, the rotating shaft 19 drives the turntable 3 to rotate, and the position of the first spring hole 20 located on the turntable 3 changes accordingly; when the first spring hole 20 rotates to be directly below the lower positioning hole 10 of the loading component 1 for receiving the spring workpiece 15, the first spring hole 20 is at the receiving position; when the first spring hole 20 rotates to be separated from the lower positioning hole 10 of the loading component 1, the second spring hole 16 is at the processing position.

[0045] In the present invention, the angle of each rotation of the turntable 3 and the rotating shaft 19 is specifically designed based on the arrangement of the first spring holes 20 on the turntable 3 (i.e., the indexing of the turntable 3). With each rotation of the turntable 3, the first spring hole 20 currently in the receiving station switches to the processing station, and the next first spring hole 20 in the processing station switches to the receiving station, and so on. In this embodiment, the angle of a single horizontal rotation of the turntable 3 caused by the torsion of the rotating shaft 19 is 14.4°.

[0046] In the present invention, N groups of feeding channels can be provided based on production requirements. That is, N first spring holes 20 can be provided in the same radial direction on the turntable 3 (that is, N circles of first spring holes 20 are provided on the turntable 3). Correspondingly, N second spring holes 16 are provided on the feeding box 6, and N third spring holes 17 are provided on the receiving box 8. Each of the N third spring holes 17 corresponds one-to-one with the N first spring holes 20 located in the same radial direction at the receiving station, achieving synchronous feeding.

The spring workpieces 15 move vertically along the axis of the second spring holes 16 of the loading cylinder. The spring workpieces 15 at the bottom of the second spring holes 16 fall into the third spring holes 17 of the receiving box 8 at the loading station. Start the horizontal pushing mechanism, drive the horizontal push rod 5 to drive the receiving box 8 to move along the chute 18 from the loading station to the unloading station. At this time, the third spring hole 17 of the receiving box 8 is aligned with the first spring hole 20 of the grinding disc assembly at the receiving station. The spring workpiece 15 in the receiving box 8 falls into the first spring hole 20 on the receiving station under the action of gravity; The rotating shaft 19 rotates to a set angle, and the first spring hole 20 currently receiving the spring workpiece 15 rotates from the receiving station to the processing station for processing, and at the same time, the first spring hole 20 at the next processing station rotates to the receiving station for receiving the material; The rotating shaft 19 rotates continuously to realize automatic continuous loading.

[0049] The device and method described in the present invention enable continuous and automatic operation of the entire process of loading, transporting, positioning, and inserting the spring workpiece 15 into the rotating disk, significantly improving production efficiency and reducing manual labor intensity. Multiple feeding channels, combined with the precise indexing rotation of the turntable 3, ensure the synchronous, efficient, and consistent filling of the first spring holes 20 in the same radial direction. The design of the fixed guide rail 11 and the slide 18 ensures the positional accuracy of the movement of the material receiving box 8 and the pressing of the spring workpiece 15 into the first spring hole 20. The feeding assembly 1 is located above the grinding disc assembly. This compact, top-mounted structural layout optimizes equipment space utilization while improving operational convenience and safety.
