[0009] Furthermore, the elastic limiting component further includes: an auxiliary conveying component, and the auxiliary conveying component is installed on the upper side of the moving plate. The auxiliary conveying component includes: a connecting seat and a hose. The connecting seat is fixedly installed on the upper side of the first circular opening, and one end of the hose is fixedly connected to the connecting seat.

[0010] Furthermore, the double-sided grinding mechanism includes: a rotating rod, a driving motor and grinding heads.

[0014] To better achieve the object of the present invention, the present invention also provides a method for an automatic loading and unloading spring end face grinding device, including the following steps: Step 1: The spring is conveyed into the spring loading mechanism through an external conveying device, and the spring loading mechanism loads the springs into the size adjustment component of the double-sided grinding mechanism one by one; Step 2: The size adjustment component drives the spring to move intermittently. The spring intermittently moves to the position of the grinding head of the double-sided grinding mechanism. The driving motor drives the grinding head to grind both ends of the spring. The lower rotating disk and the upper rotating disk of the size adjustment component rotate to the position of the left-side slot supported by the circular support base, and the spring automatically falls for blanking; Step 3: The photoelectric sensor of the blanking detection mechanism detects the lower rotating disk and the upper rotating disk. When it is detected that the spring does not automatically fall for blanking, the second cylinder of the blanking detection mechanism drives the connecting plate and the top rod to move downward, pushing out the spring, and the spring falls from the slot position on the front side of the circular support base to complete auxiliary blanking.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, a spring is conveyed from a hose into a connecting seat through an external conveying mechanism. At this time, springs to be processed are arranged in the first circular openings of both the connecting seat and the moving plate. One spring is located between the connecting seat and the first circular opening, and the other spring is located within the first circular opening. The output end of the first cylinder extends to drive the moving plate to move forward. When the moving plate moves forward, the first circular opening on the moving plate coincides with the second circular opening on the support plate, causing the spring within the first circular opening to fall. As the moving plate moves forward, the sliding rod of the elastic limiting component further enters the moving plate, pressing against the spring between the connecting seat and the first circular opening, preventing the spring from moving downward. At this time, when the sliding rod moves backward, the spring undergoes elastic deformation, and the spring provides an elastic supporting force for the sliding rod, preventing excessive relative displacement between the sliding rod and the moving plate and resulting in spring damage, which is beneficial for feeding springs one by one. 2. When the spring within the first circular opening falls into the third circular openings on the upper rotating disk and the lower rotating disk of the size adjustment component, the lower side of the spring is supported by a circular support seat at this time, ensuring that the spring always remains within the third circular opening. The indexing disk rotates intermittently, driving the lower rotating disk and the upper rotating disk to rotate intermittently, causing the spring within the third circular opening to move intermittently. When the spring moves to the position of the grinding head, the upper and lower ends of the spring are ground by the grinding head. After grinding, the spring continues to move intermittently and moves to the grooved position on the left side of the circular support seat. At this time, the ground spring loses the support of the circular support seat and falls for discharging. By unscrewing the adjusting screw, the distance between the lower rotating disk and the upper rotating disk can be adjusted to adapt to springs of different lengths. Tightening the adjusting screw fixes the lower rotating disk and the upper rotating disk together, which is beneficial for double-end grinding and automatic discharging of springs of different lengths.

Specific embodiments

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0022] Embodiment 1: In some embodiments, please refer to Figures 1 - 8, A spring end face grinding and leveling device with automatic loading and unloading, including a frame 1, and also including: a spring loading mechanism 2, a double-sided grinding mechanism 3, and a blanking detection mechanism 4. The spring loading mechanism 2 is installed on the right side of the frame 1, the double-sided grinding mechanism 3 is installed on the rear side of the frame 1, and the blanking detection mechanism 4 is installed on the front side of the frame 1. The spring loading mechanism 2 includes: a vertical plate 21, a support plate 22, a fixed rod 23, a slider 24, a moving plate 25, and a first cylinder 26. The vertical plate 21 is fixedly installed on the right side of the frame 1, the support plate 22 is fixedly installed on the vertical plate 21, two fixed rods 23 are fixedly installed on the support plate 22, the slider 24 is slidably connected to the fixed rod 23 and can slide back and forth on the fixed rod 23, the moving plate 25 is fixedly installed on the slider 24, three through first circular openings 27 are formed in the moving plate 25, three through second circular openings 28 are formed in the support plate 22, the first cylinder 26 is fixedly installed on the front side of the support plate 22, and the output end of the first cylinder 26 is fixedly connected to the front side wall of the moving plate 25. The spring loading mechanism 2 further includes: an elastic limiting component, and the elastic limiting component is installed on the rear side of the support plate 22.

[0023] The spring loading mechanism 2 feeds the springs 213 one by one. The double-sided grinding mechanism 3 grinds both sides of the springs 213, and the double-sided grinding mechanism 3 can adapt to springs 213 of different lengths. The blanking detection mechanism 4 detects and assists in blanking the springs 213 to avoid jamming of the subsequent loaded materials caused by incomplete blanking of the springs 213.

[0024] As Figure 6 , Figure 7 shown, the springs 213 are conveyed by an external vibrating disk and other conveying mechanisms and are conveyed into the first circular openings 27 of the moving plate 25 of the spring loading mechanism 2. The output end of the first cylinder 26 extends to drive the moving plate 25 to move forward. The forward movement of the moving plate 25 makes the first circular openings 27 on the moving plate 25 coincide with the second circular openings 28 on the support plate 22, so that the springs 213 in the first circular openings 27 fall to the double-sided grinding mechanism 3, realizing the loading of the springs 213.

[0025] The elastic limiting assembly includes: a rear side plate 29, a moving column 210, a fixing screw 211, a sliding rod 212 and a spring 213. The rear side plate 29 is fixedly installed on the rear side of the support plate 22, and the three moving columns 210 are slidably connected to the rear side plate 29. A fixing screw 211 is provided on the upper side of each moving column 210. The fixing screw 211 is threadedly connected to the rear side plate 29. One end of the fixing screw 211 located in the rear side plate 29 is close to the moving column 210. The fixing screw 211 is used to fix the moving column 210 on the rear side plate 29. The rear side of the sliding rod 212 is slidably connected to the moving column 210. One end of the spring 213 is fixedly installed in the moving column 210, and the other end of the spring 213 is fixedly installed on the end of the sliding rod 212 located inside the moving column 210. The front side of the sliding rod 212 is slidably connected to the moving plate 25.

[0026] The elastic limiting assembly also includes: an auxiliary conveying assembly, which is installed on the upper side of the movable plate 25. The auxiliary conveying assembly includes: a connecting seat 214 and a hose 215. The connecting seat 214 is fixedly installed on the upper side of the first circular opening 27, and one end of the hose 215 is fixedly connected to the connecting seat 214.

[0027] Multiple springs 213 are continuously transported to the hose 215 of the auxiliary conveying assembly through the external conveying mechanism, and enter the connecting seat 214 through the hose 215. At this time, the connecting seat 214 and the first circular opening 27 of the movable plate 25 are both provided with springs 213 to be processed. One spring 213 is located between the connecting seat 214 and the first circular opening 27, and the other spring 213 is located in the first circular opening 27. The output end of the first cylinder 26 is extended to drive the movable plate 25 to move forward. The movable plate 25 moves forward so that the first circular opening 27 on the movable plate 25 and the support plate 2 2 coincides with the second circular opening 28 on the upper and lower parts, causing the spring 213 in the first circular opening 27 to fall down. The movable plate 25 moves forward, causing the sliding rod 212 of the elastic limiting assembly to further enter the movable plate 25, and press the spring 213 between the connecting seat 214 and the first circular opening 27, so that the spring 213 will not move downward. At this time, the sliding rod 212 moves backward, causing the spring 213 to be elastically deformed. The spring 213 provides elastic supporting force for the sliding rod 212, preventing the relative displacement between the sliding rod 212 and the movable plate 25 from being too large, which may cause damage to the spring 213.

[0028] After the spring 213 inside the first circular opening 27 drops, the output end of the first cylinder 26 shortens and moves backward, driving the moving plate 25 to move backward. The backward movement of the moving plate 25 causes the first circular opening 27 on the moving plate 25 and the second circular opening 28 on the support plate 22 to be misaligned. At this time, the moving plate 25 leaves the sliding rod 212 and returns to its initial position. At this time, the sliding rod 212 no longer presses against the spring 213 between the connecting seat 214 and the first circular opening 27, and the spring 213 drops into the first circular opening 27. The spring 213 inside the hose 215 drops and falls between the connecting seat 214 and the first circular opening 27, completing the feeding of the springs 213 one by one.

[0029] Embodiment 2: In some embodiments, as Figures 1 - 8 shown, as a preferred embodiment of the present invention, the double-sided grinding mechanism 3 includes: a rotating rod 31, a driving motor 32, and a grinding head 33. The rotating rod 31 is rotatably connected to the frame 1. The driving motor 32 is fixedly installed on the lower side of the frame 1. The output shaft of the driving motor 32 is fixedly connected to the lower side of the rotating rod 31. Two grinding heads 33 are fixedly installed on the upper side of the rotating rod 31.

[0030] The output shaft of the driving motor 32 of the double-sided grinding mechanism 3 rotates to drive the rotating rod 31 to rotate, and the rotating rod 31 rotates to drive the two grinding heads 33 to rotate.

[0031] The double-sided grinding mechanism 3 further includes: a size adjustment component. The size adjustment component is installed on the front side of the frame 1. The size adjustment component includes: a circular support seat 34, a lower rotating disk 35, an upper rotating disk 36, an adjustment screw 37, and a dividing disk 38. The circular support seat 34 is fixedly installed on the front side of the frame 1. Both the left side and the front side of the circular support seat 34 are provided with slots 39. The lower rotating disk 35 is rotatably connected to the frame 1 through a rotating shaft. The upper rotating disk 36 is arranged on the upper side of the lower rotating disk 35. The upper sides of a plurality of adjustment screws 37 are threadedly connected to the upper rotating disk 36, and the lower sides of the adjustment screws 37 are threadedly connected to the lower rotating disk 35. The dividing disk 38 is fixedly installed on the lower side of the frame 1. The output shaft of the dividing disk 38 is fixedly connected to the rotating shaft of the lower rotating disk 35. A plurality of third circular openings 310 are provided on both the lower rotating disk 35 and the upper rotating disk 36, and the third circular openings 310 on the lower rotating disk 35 and the upper rotating disk 36 correspond to each other one by one.

[0032] As Figure 3 、 Figure 4 、 Figure 8As shown, the spring 213 inside the first circular opening 27 drops and lands in the third circular opening 310 on the upper rotating disk 36 and the lower rotating disk 35 of the size adjustment assembly. At this time, the lower side of the spring 213 is supported by the circular support base 34, so that the spring 213 is always located inside the third circular opening 310. The indexing disk 38 intermittently rotates to drive the lower rotating disk 35 and the upper rotating disk 36 to intermittently rotate, causing the spring 213 inside the third circular opening 310 to intermittently move. When the spring 213 moves to the position of the grinding head 33, the upper and lower ends of the spring 213 are ground by the grinding head 33. After grinding, the spring 213 continues to intermittently move and moves to the slot 39 on the left side of the circular support base 34. At this time, the ground spring 213 loses the support of the circular support base 34 and the spring 213 drops for blanking.

[0033] When double-end grinding springs 213 of different lengths, the distance between the lower rotating disk 35 and the upper rotating disk 36 can be adjusted by unscrewing the adjustment screw 37 to adapt to springs 213 of different lengths. Tighten the adjustment screw 37 so that the lower rotating disk 35 and the upper rotating disk 36 are fixed together, and synchronously adjust the position between the vertical plate 21 and the support plate 22 so that the spring feeding mechanism 2 can feed materials normally.

[0034] The blanking detection mechanism 4 includes: a front support 41, a second cylinder 42, a connecting plate 43 and a ejector rod 44. The front support 41 is fixedly installed on the front side of the frame 1, the second cylinder 42 is fixedly installed in the middle side of the front support 41, the connecting plate 43 is fixedly installed on the output end of the second cylinder 42, and a plurality of the ejector rods 44 are fixedly installed on the lower side of the connecting plate 43.

[0035] The blanking detection mechanism 4 further includes: an extension plate 45 and a photoelectric sensor 46. The extension plate 45 is fixedly installed on the left side of the front support 41, and a plurality of the photoelectric sensors 46 are fixedly installed on the extension plate 45.

[0036] As Figure 1 、 Figure 2 、 Figure 5 As shown, a plurality of photoelectric sensors 46 on the extension plate 45 detect the third circular opening 310. If the spring 213 does not automatically drop for blanking, the photoelectric sensor 46 will transmit an electrical signal to the external controller after detection. The external controller controls the output end of the second cylinder 42 to extend. The extension of the output end of the second cylinder 42 drives the connecting plate 43 to move downward. The downward movement of the connecting plate 43 drives the ejector rod 44 to move downward. A plurality of ejector rods 44 move downward into the third circular opening 310 to push the spring 213 in the third circular opening 310 down. The spring 213 drops from the slot 39 on the front side of the circular support base 34 to complete auxiliary blanking, avoiding jamming caused by incomplete blanking of the spring 213 leading to subsequent feeding.

[0037] Embodiment 3: In some embodiments, such as Figures 1 - 8 shown, as a preferred embodiment of the present invention, a method for an automatic loading and unloading spring end face grinding equipment includes the following steps: Step 1: The spring 213 is conveyed to the spring loading mechanism 2 through an external conveying device, and the spring loading mechanism 2 loads the springs 213 one by one into the size adjustment component of the double-sided grinding mechanism 3; Step 2: The size adjustment component drives the spring 213 to move intermittently. The spring 213 moves intermittently to the position of the grinding head 33 of the double-sided grinding mechanism 3. The drive motor 32 drives the grinding head 33 to grind both ends of the spring 213. The lower rotating disk 35 and the upper rotating disk 36 of the size adjustment component rotate to the position of the left side slot 39 supported by the circular support base 34, and the spring 213 automatically falls for unloading; Step 3: The photoelectric sensor 46 of the unloading detection mechanism 4 detects the lower rotating disk 35 and the upper rotating disk 36. When it is detected that the spring 213 does not automatically fall for unloading, the second cylinder 42 of the unloading detection mechanism 4 drives the connecting plate 43 and the ejector rod 44 to move downward to push out the spring 213, and the spring 213 falls from the slot 39 position in front of the circular support base 34 to complete the auxiliary unloading.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

8. A method for an automatic loading and unloading spring end face grinding equipment, which is used for the automatic loading and unloading spring end face grinding equipment described in claim 7, characterized in that, It includes the following steps: Step 1: The spring (213) is conveyed into the spring feeding mechanism (2) through an external conveying device. The spring feeding mechanism (2) feeds the springs (213) into the size adjustment component of the double-sided grinding mechanism (3) one by one. Step 2: The size adjustment component drives the spring (213) to move intermittently. The spring (213) moves intermittently to the position of the grinding head (33) of the double-sided grinding mechanism (3). The driving motor (32) drives the grinding head (33) to grind both ends of the spring (213). The lower rotating disk (35) and the upper rotating disk (36) of the size adjustment component rotate to the position of the left side slot (39) supported by the circular support base (34), and the spring (213) automatically falls for blanking. Step 3: The photoelectric sensor (46) of the blanking detection mechanism (4) detects the lower rotating disk (35) and the upper rotating disk (36). When it is detected that the spring (213) does not automatically fall for blanking, the second cylinder (42) of the blanking detection mechanism (4) drives the connecting plate (43) and the ejector rod (44) to move downward, pushing out the spring (213), and the spring (213) falls from the slot (39) position on the front side of the circular support base (34) to complete the auxiliary blanking.
