Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spring end face cutting, in particular to a long spring end face laser cutting device. BACKGROUND

[0002] A spring is a mechanical part that works by using elasticity. The part made of elastic material deforms under the action of external force and restores to its original shape after the external force is removed. As one of the basic parts and components, the spring plays a crucial role in mechanical equipment in various fields.

[0003] At present, there is a cutting step in the spring processing link, and the spring cutting is divided into mechanical cutting and laser cutting. The mechanical cutting has greater wear on the spring, while the laser cutting is superior to the mechanical cutting and can reduce the damage degree of the spring cutting end face.

[0004] However, the existing laser cutting device still has some disadvantages during actual use. Due to the influence of the spring structure, it is difficult for the laser beam to effectively ensure that the spring end face is cut into an effective circular structure.

The spring position adjusting mechanism 100 is used to provide a rotating progressive support platform for the long spring 200 and reduce abnormal shaking of the long spring 200 during rotating progression. The spring face positioning mechanism 300 is used to calibrate and clamp the part to be cut of the long spring 200. The cutting angle adjusting mechanism 400 cooperates with the spring face positioning mechanism 300 to cut the clamped part of the long spring 200 at an angle.

[0050] The spring end clamp 360 is internally provided with an inclined hole, and the inclined hole is used for providing calibrated clamping for the to-be-cut part of the long spring 200;

[0054] When the long spring 200 is uniformly driven to rotate along the outside of the spring position adjusting mechanism 100, the part of the long spring 200 penetrating into the inclined hole in the spring end clamp 360 can be effectively calibrated and clamped;

[0055] Then the motor 3301 is started, and when the motor 3301 is running, the internal transmission shaft of the motor 3301 matches the gear 3302 to drive the gear sleeve 4102 to rotate along the column 340 as the axis, and the supporting plate 4103 and the suspension 440 as a whole rotate around the spring end clamp 360, and at the same time, the laser cutter 500 also needs to be started;

[0056] At this time, the rays released by the started laser cutter 500 effectively encircle the part of the long spring 200 inserted into the spring end clamp 360, and at the same time, according to the gradual change of the curved surface of the long spring 200, by running the hydraulic part 430, until the internal hydraulic sub-rod drives the hydraulic part 430 and the chuck 4301 to stretch, finally the suspension 440 tilts around the supporting plate 4103 as the axis, and the rays released by the laser cutter 500 can effectively cut the gradually changing curved surface of the long spring 200, so as to ensure that the cutting surface of the long spring 200 always maintains an effective circular structure.

[0059] The inside of the stabilizing beam plate 160 is provided with a plurality of insertion holes distributed at equal intervals;

[0060] One end of the stabilizing beam plate 160 close to the long spring 200 is provided with two symmetrical fan-shaped protrusions, and adjacent two fan-shaped protrusions are used to provide limiting constraint for the long spring 200.

[0061] Preferably, two oval holes are formed in the inside of the base 110, and the base 110 is fixed on the workbench by bolts, and when the spring position mechanism 100 as a whole is in a suspended state, the long spring 200 rotating along the outside of the cross beam 130 and along the outside of the two stabilizing beam plates 160 can be unblocked and advanced;

[0062] According to the actual length of the long spring 200 to be processed, the two stability beam plates 160 are pushed outward horizontally in advance until the two stability beam plates 160 are elongated with the base 120, and the limit guide of the outermost end of the long spring 200 is matched with the fan-shaped protrusions at the outer ends of the two stability beam plates 160, so that abnormal shaking of the long spring 200 during cutting can be avoided. Embodiment 3

[0063] In combination Figures 6 to 8 As shown in the drawings, on the basis of embodiment 1, the spring surface coordination mechanism 300 further comprises a clamping seat 370 arranged outside the stability beam plate 160, two first bolts 3701 inserted into the clamping seat 370 and fixed in the stability beam plate 160, and a first lead screw 3702 movably mounted inside the clamping seat 370;

[0064] The inner end of the first lead screw 3702 is movably mounted in the clamping seat 370;

[0065] The surfaces of the circular protective pad 320 and the spring end clamping piece 360 are coated with an opaque coating, and a U-shaped groove is formed at the top end of the spring end clamping piece 360 for providing calibration guidance to the part to be cut of the long spring 200;

[0066] The protective neck sleeve 3102 has an overall H-shaped structure, and a partition plate is arranged at the top of the protective neck sleeve 3102, and a threaded slot hole is formed in the interior of the partition plate;

[0068] Preferably, the rod sleeve 310 is fixed to the outside of the cross beam 130 by bolts, and a square hole adapted to the limit shaft sleeve 3502 is formed in the interior of the spring end clamping piece 360;

[0069] Specifically, by adjusting the rotation of the first lead screw 3702, the first lead screw 3702 will extend along the threaded slot hole in the interior of the partition plate, and the first lead screw 3702 will carry the spring end clamping piece 360 to slide along the outside of the limit shaft sleeve 3502. At this time, the part of the long spring 200 clamped by the spring end clamping piece 360 can be calibrated and leveled with the end of the released radiation at the bottom end of the laser cutter 500, thereby improving the effectiveness and flatness of the cutting of the calibrated part of the long spring 200. Embodiment 4

[0070] In combination Figure 7 And Figure 9 As shown in the drawings, on the basis of embodiment 1, the cutting angle adjusting mechanism 400 further comprises a top plate 450 arranged in the top slot of the sliding seat 460, two second bolts 4501 inserted into the top plate 450 and fixed in the sliding seat 460, a second lead screw 4502 threadedly mounted in the middle of the top plate 450, and a spring 4503 arranged outside the second lead screw 4502 and bearing on the sliding block 4505.

[0071] The bottom end of the second screw rod 4502 is movably installed in the sliding block 4505.

[0072] Preferably, the inside of the sliding seat 460 is provided with a vertical slot, and the second screw rod 4502 is located in the middle of the inside of the vertical slot.

[0073] Specifically, after the two second bolts 4501 fix the top plate 450 on the top of the sliding seat 460, the sliding seat 460 drives the laser cutter 500 to approach the spring end clamping piece 360 by reversing the top end rotating wheel of the second screw rod 4502, and the distance between the laser cutter 500 and the spring end clamping piece 360 is adjusted to improve the cutting efficiency of the clamped part of the long spring 200.

[0074] The working principle and use process of the present application are as follows: the base 110 is fixed and installed on the workbench by bolts in advance, then the long spring 200 to be processed is preassembled along the back of the base 120, then the long spring 200 is rotated along the outside of the cross beam 130 until one end of the long spring 200 is inserted into the two ring grooves 1201, and finally the rotated long spring 200 is effectively supported by the two stabilizing beam plates 160.

[0075] After the end of the long spring 200 to be cut is inserted into the inclined hole in the spring end clamping piece 360, the part to be cut of the long spring 200 can be calibrated and limited, according to the curved surface requirement of the part to be cut of the long spring 200, by operating the hydraulic part 430, the end rod 4401 movably installed in the other end of the traction part 4302 is pushed to tilt the suspension 440 along the top end of the bearing plate 4103, and the tilted suspension 440 controls the back plate 4504 and the sliding seat 460 to roll over, and finally the angle between the cutting end of the laser cutter 500 at the bottom and the part to be cut of the long spring 200 can be adjusted.

[0076] When the angle between the bottom cutting end of the laser cutter 500 and the end face of the long spring 200 to be cut is set, the laser cutter 500 is then started, and the laser cutter 500 releases the laser to longitudinally cut the selected part of the long spring 200. During the longitudinal cutting of the long spring 200, the motor 3301 is started again, and the transmission shaft in the motor 3301 cooperates with the gear 3302 to help rotate the gear sleeve 4102, the buckle plate 410, and the bearing plate 4103 along the stand 340. The laser released by the laser cutter 500 can accurately circle the selected part of the long spring 200 that is clamped, thereby ensuring that the cut end face of the long spring 200 maintains a regular circular structure. At this time, the laser cutter 500 that is adjusted in angle and rotates regularly can effectively cut the clamped part of the long spring 200, thereby avoiding the problem of irregularity and abnormal deformation of the cut end face of the long spring 200.

[0077] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments 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.
