[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] The purpose of this specific implementation is to provide a spring chamfering machine to solve the problems that the spring chamfering machine cannot complete automatic chamfering, has low processing efficiency, and has high labor intensity for workers.

[0029] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0030] See also Figure 1-6 In this embodiment, a spring chamfering machine includes a loading and unloading conveying mechanism 1, a sanding belt rotating mechanism 3 and a spring rotating mechanism 4. The loading and unloading conveying mechanism 1 is used to convey the spring, such as Figure 2As shown, a plurality of spring V-plates 2 for placing springs are provided on the loading and unloading conveying mechanism 1. Each spring V-plate 2 moves with the loading and unloading conveying mechanism 1, thereby driving the springs placed on the spring V-plate 2 to move. The spring V-plate 2 is provided with a V-shaped groove with a V-shaped cross section. The spring can be directly placed in the V-shaped groove. The length direction of the spring V-plate 2 is consistent with the width direction of the loading and unloading conveying mechanism 1. After the spring is placed on the spring V-plate 2, the axial direction of the spring is consistent with the width direction of the loading and unloading conveying mechanism 1. Figure 1 As shown, along the width direction of the loading and unloading conveying mechanism 1, the abrasive belt rotating mechanism 3 and the spring rotating mechanism 4 are respectively arranged on opposite sides of the loading and unloading conveying mechanism 1. Figure 3 As shown, the abrasive belt rotating mechanism 3 includes at least two pulleys 31, abrasive belts 32 wound around each pulley 31, a spring positioning head 33 and a first telescopic assembly for driving the spring positioning head 33 to reciprocate along the width direction of the loading and unloading conveying mechanism 1, and the spring positioning head 33 can abut against the end of the spring. In this solution, the number of pulleys 31 is 3, and the middle pulley 31 has a tensioning effect on the abrasive belt 32. Figure 5 As shown, the spring rotating mechanism 4 includes a spring shaft 41 for driving the spring to rotate, a second power device for driving the spring shaft 41 to rotate, and a second telescopic component for driving the spring shaft 41 and the second power device to reciprocate along the width direction of the loading and unloading conveying mechanism 1. The second power device is a second motor 48. The axis of the spring positioning head 33 and the axis of the spring shaft 41 are located on the same straight line. The second telescopic component drives the spring shaft 41 and the spring to move in the direction close to the spring positioning head 33 until the end of the spring is matched with the spring positioning head 33, and the end of the spring is against the sanding belt 32. Optionally, the first telescopic component and the second telescopic component can be cylinders or automatic telescopic rods. After one end of the spring is chamfered, the first telescopic component extends and the second telescopic component retracts, pushing the spring with one end chamfered back onto the spring V-plate 2, and the spring continues to move with the loading and unloading conveying mechanism 1. It should be noted that the "width direction" of the loading and unloading conveying mechanism 1 mentioned above is as follows. Figure 1 The loading and unloading conveying mechanism 1 shown in the figure is placed in a state, that is, Figure 1 The direction from the left end to the right end of the loading and unloading conveying mechanism 1 is the “width direction” of the loading and unloading conveying mechanism 1 .

[0031] When chamfering the springs, multiple springs are placed one by one on each spring V-plate 2, the loading and unloading conveying mechanism 1 is started, the second telescopic component starts to telescope back and forth, the second power device drives the spring shaft 41 to rotate synchronously, and each spring moves along the conveying direction with the loading and unloading conveying mechanism 1. When the spring moves to the corresponding position of the spring rotating mechanism 4 and the abrasive belt rotating mechanism 3, the second telescopic component extends and makes the spring shaft 41 cooperate with the spring, driving the spring to move in the direction close to the abrasive belt 32 until the end of the spring cooperates with the spring positioning head 33 and is pressed against the abrasive belt 32, so that the abrasive belt 32 chamfers the end of the spring, and the remaining springs are moved to the corresponding positions of the spring rotating mechanism 4 and the abrasive belt rotating mechanism 3 in turn, and the remaining springs are chamfered in turn.

[0032] With such an arrangement, the device can automatically complete spring chamfering, shorten the spring chamfering time, reduce the labor intensity of workers, and improve work efficiency, thus solving the problem that the spring chamfering machine in the prior art cannot complete automatic chamfering, has low processing efficiency, and has high labor intensity for workers.

[0033] As a preferred embodiment, the number of the abrasive belt rotating mechanism 3 and the spring rotating mechanism 4 are both two. Figure 1 As shown, the two abrasive belt rotating mechanisms 3 are respectively located on both sides of the upper and lower material conveying mechanism 1, and the two spring rotating mechanisms 4 are respectively located on both sides of the upper and lower material conveying mechanism 1, and the two abrasive belt rotating mechanisms 3 and the two spring rotating mechanisms 4 are arranged in a one-to-one correspondence. Figure 1 As shown, the abrasive belt rotating mechanism 3 and the spring rotating mechanism 4 are a group. The device includes two groups, which are arranged at intervals along the length direction of the loading and unloading conveying mechanism 1.

[0034] With such arrangement, after the first end of the spring is chamfered, it continues to move driven by the loading and unloading conveying mechanism 1. When the spring moves to the position where the next spring rotating mechanism 4 and the abrasive belt rotating mechanism 3 are located, the above steps are repeated to chamfer the second end of the spring. In this way, the device can automatically chamfer both ends of the spring, further saving manpower and improving processing efficiency.

[0035] As an optional embodiment, the spring positioning head 33 includes a first rod and a first conical head disposed on the first rod, the spring shaft 41 includes a second rod 4101 and a second conical head 4102 disposed on the second rod 4101, the diameter of any cross section of the first conical head and the second conical head 4102 is smaller than the inner diameter of the spring, the diameters of the first rod 4101 and the second rod 4101 are larger than the inner diameter of the spring, the axis of the spring positioning head 33 and the axis of the spring shaft 41 are located on the same straight line, so that the first conical head and the second conical head 4102 extend into the interior of the spring, and the first rod 4101 and the second rod 4101 are against the end of the spring. The telescopic direction of the first telescopic assembly and the telescopic direction of the second telescopic assembly are consistent with the axial direction of the spring placed on the spring V plate 2.

[0036] In this way, the axis of the spring locating head 33 and the axis of the spring rotating shaft 41 are located on the same straight line, the telescopic movement directions of the two are the same and are consistent with the width direction of the loading and unloading conveying mechanism 1. When the spring is placed on the spring V-plate 2, the axial direction of the spring is also consistent with the width direction of the loading and unloading conveying mechanism 1, so the first conical head of the spring locating head 33 and the second conical head 4102 of the spring rotating shaft 41 can respectively extend into the interior of the spring from both ends of the spring, and the first rod portion of the spring locating head 33 and the second rod portion 4101 of the spring rotating shaft 41 can respectively abut against the two ends of the spring. In this way, when one of the first telescopic component and the second telescopic component is extended and the other is retracted, the spring can be moved and abutted against the sanding belt 32, and the spring with one end chamfered can be put back on the spring V-plate 2.

[0037] like Figure 2 As shown, the loading and unloading conveying mechanism 1 includes a conveying chain 11, a sprocket 12 matched with the conveying chain 11, and a third power device for driving the sprocket 12 to rotate. Each spring V plate 2 is fixed on the conveying chain 11, and the third power device is a third motor 13, which is in transmission connection with the sprocket 12 to drive the sprocket 12 to rotate. The loading and unloading conveying mechanism 1 also includes a third motor mounting plate 14 and a conveying chain mounting plate 15.

[0038] With such arrangement, the structure of the loading and unloading conveying mechanism 1 is refined, and the spring V plate 2 fixed on the conveying chain 11 is driven to move by the third motor 13 , the sprocket wheel 12 and the conveying chain 11 .

[0039] like Figure 3 As shown, the first telescopic assembly includes a first cylinder 34, a first push plate 35 arranged on the cylinder rod of the first cylinder 34, and a spring positioning head 33 is arranged on the first push plate 35. The sanding belt rotating mechanism 3 also includes a frame 36, a pulley mounting plate 37 and a first power device arranged on the pulley mounting plate 37 for driving the pulley 31 to rotate, as shown in FIG. Figure 4 As shown, the first power device is a first motor 38, and a pulley mounting plate 37 is rotatably arranged on a frame 36 so that different positions of the sanding belt 32 can contact the spring. In the horizontal direction, there is a gap between the pulley mounting plate 37 and the frame 36 for the pulley mounting plate 37 to rotate.

[0040] With such arrangement, when the loading and unloading conveying mechanism 1 is started, the first motor 38 is started synchronously, so that the first motor 38 drives the pulley 31 to rotate and thus drives the sanding belt 32 to rotate. When the spring is pressed against the sanding belt 32, the spring and the sanding belt 32 rotate simultaneously to chamfer the spring; the pulley mounting plate 37 is rotatably arranged on the frame 36 so that more effective surfaces of the sanding belt 32 can rub against the spring, thereby improving the utilization rate of the sanding belt 32 and further improving the chamfering efficiency of the spring.

[0041] Specifically, Figure 4 As shown, a mounting shaft 39 is provided on the frame 36, and the frame 36 includes two parallel and spaced mechanism mounting plates 311, and the two ends of the mounting shaft 39 are respectively connected to the two mechanism mounting plates 311, and the pulley mounting plate 37 is rotatably provided on the mounting shaft 39 through two connecting plates 312. Optionally, the two mounting plates 312 can be rotatably connected to the mounting shaft 39 through bearings. A third telescopic assembly is provided on the frame 36, and the third telescopic assembly is movably connected to the end of the pulley mounting plate 37 so that the pulley mounting plate 37 is driven to rotate around the mounting shaft 39 when the third telescopic assembly telescopes back and forth. The third telescopic assembly is a third cylinder 310, and the cylinder rod of the third cylinder 310 is movably connected to the lower end of the pulley mounting plate 37.

[0042] With such arrangement, the third cylinder 310 performs telescopic reciprocating motion, pushing the pulley mounting plate 37 to reciprocate around the mounting shaft 39, so that the pulley mounting plate 37 can be rotatably connected to the frame 36, so that more effective surface of the sanding belt 32 rubs against the spring, thereby improving the utilization rate of the sanding belt 32.

[0043] As a preferred embodiment, Figure 5 As shown, the spring rotating mechanism 4 also includes a base 42, a guide rail arranged on the base 42, a slider matched with the guide rail, and a slider 45 fixedly arranged on the slider, the second power device and the spring shaft 41 are both arranged on the slider 45, and the guiding direction of the guide rail is consistent with the telescopic direction of the second telescopic assembly. The second power device is a second motor 48, the spring shaft 41 is arranged on the slider 45 through a bearing seat 49 and a bearing, and the spring shaft 41 is connected to the second motor 48 through a coupling 410.

[0044] Specifically, the guide rail is a linear slide rail 43, the slider is a linear slider 44, and the second telescopic assembly includes a second cylinder 46 fixed on the base 42 through a second cylinder fixing plate 411 and a second push plate 47 arranged on the cylinder rod of the second cylinder 46. The second push plate 47 is fixedly connected to the slide plate 45 so that the second cylinder 46 drives the spring shaft 41 to telescope and reciprocate.

[0045] With this arrangement, the second motor 48 drives the spring shaft 41 to rotate, and the second cylinder 46 drives the second motor 48 and the spring shaft 41 to telescope and reciprocate, so that the spring shaft 41 can both rotate and reciprocate along the width direction of the loading and unloading conveying mechanism 1.

[0046] As a preferred embodiment, the spring chamfering machine further comprises a feed chute 5 located at the end of the loading and unloading conveying mechanism 1 , and along the transport direction of the loading and unloading conveying mechanism 1 , the feed chute 5 is located downstream of the loading and unloading conveying mechanism 1 .

[0047] With such arrangement, the spring moved to the end of the loading and unloading conveying mechanism 1 as the loading and unloading conveying mechanism 1 falls into the unloading trough 5, completing the automatic unloading of the spring chamfering machine, further improving the production efficiency.

[0048] In this device, the loading and unloading conveying mechanism, the spring rotating mechanism 4 and the abrasive belt rotating mechanism 3 work together to realize automatic chamfering of both ends of the spring, solving the problems that the spring chamfering machine in the prior art cannot complete automatic chamfering, has low processing efficiency and high labor intensity for workers.

The multiple solutions provided by the present invention include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0050] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
