Description

Technical Field

[0001] This invention relates to the field of piston rod feeding, specifically to a piston rod feeding device. Background Technology

[0002] In piston rod processing, the process from material preparation includes preliminary machining, rough turning, heat treatment and straightening, precision machining, surface treatment, and final inspection, followed by packaging and warehousing. Piston rods have high working strength and high precision requirements. After surface treatment, it is necessary to protect the piston rod and avoid damage caused by collisions and scratches during transportation and packaging. Therefore, piston rods after surface treatment need to be handled carefully during the final unloading process (transportation, inspection, and packaging). Timely inspection and packaging after surface treatment, as well as shortening the transportation distance and reducing contact, are effective ways to reduce piston rod damage.

[0003] Existing technology uses a conveyor belt to transport materials to the testing station, and then to the packaging station after testing. The long piston rod occupies a large amount of lateral space and is unstable on the conveyor belt, making long-distance testing and packaging not timely enough. Summary of the Invention

[0004] The purpose of this invention is to provide a piston rod feeding device to solve the technical problems mentioned in the background art, such as long feeding distance and untimely detection and packaging of existing piston rods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A piston rod feeding device includes a conveying mechanism, a detection mechanism and a covering mechanism connected in sequence on the conveying mechanism. The conveying mechanism includes a conveying frame, a connecting rod rotatably connected to the conveying frame, a rotating conveying screw rod sleeved on the connecting rod, a slide rod inserted into the side of the conveying screw rod, the slide rod inserted into the bottom of the slide block, the slide block sliding in a groove provided on the conveying frame, a bracket rotatably connected to the slide block, an adjusting gear fixedly connected below the bracket to the adjusting gear surface on the conveying frame, and a tilting frame connected to the two ends of the conveying screw rod.

[0006] Preferably, the conveying screw is provided with a deep spiral groove and a shallow spiral groove, the spiral directions of the deep spiral groove and the shallow spiral groove are opposite, and the slide rod slides in the deep spiral groove and the shallow spiral groove respectively.

[0007] Preferably, the connecting rod passes through the middle of the conveying screw, and two tilting frames are respectively provided with a locking plate on opposite sides, which engages with the locking groove provided on the side of the slider.

[0008] Preferably, one end of the pressure cylinder is fixedly connected to the conveyor frame, and the other end of the pressure cylinder is rotatably connected to the pressure wheel, with the pressure wheel abutting against the side of the slider.

[0009] Preferably, the conveyor frame is provided with directional gears on the upper and lower sides, a rotating sleeve is fixedly connected to the bottom of the directional gear, a rotating rod is fixedly connected to the top of the slider, the rotating rod rotates inside the rotating sleeve, and an elastic wear-resistant plate is fixed to the part of the rotating rod inside the rotating sleeve.

[0010] Preferably, the bracket includes a support plate fixedly connected to the bushing, a V-shaped frame fixed on the support plate, a rotating wheel rotatably connected to the V-shaped frame, a V-shaped rotating belt wound around the rotating wheel, one of the rotating wheels being connected to a rotating gear, and the rotating gear engaging with a rotating tooth surface provided on the conveyor frame.

[0011] Preferably, the coating mechanism includes a lifting frame, which is connected to a unwinding drum. A coating wheel, rotatably connected to the lifting frame, is located below the unwinding drum, and a clamping and cutting tool is connected to the side of the coating wheel.

[0012] Preferably, the clamping and cutting tool includes a clamping blade and a shearing blade, wherein the inner arc surface of the clamping blade and the outer arc surface of the shearing blade form a clamping part, and the cutting edge of the shearing blade and the cutting plate of the clamping blade form a shearing part.

[0014] Preferably, the testing mechanism includes a testing frame, on which a testing camera and an ultrasonic probe are connected.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. A rotatable bracket is connected to the conveyor frame. After the piston rod is placed on the bracket, the piston rod moves parallel to the conveying direction through the engagement of the directional gear and the directional tooth surface, reducing the lateral space occupied. During the movement, detection and packaging are carried out, shortening the conveying distance and improving the conveying stability. 2. The bracket adopts a V-shaped frame connected to a rotating belt, which can stably support different models of piston rods and reduce the contact area. The rotating belt can rotate under the cooperation of the rotating gear and the rotating tooth surface, so that the piston rod rotates during the movement, which can enable more comprehensive inspection and facilitate packaging. 3. The shearing blade with clamping part in the coating mechanism can clamp the coating film and pass it under the coating wheel. The coating wheel presses the coating film onto the piston rod. As the piston rod rotates and moves, the unwinding motor releases the coating film synchronously. Under the action of the coating wheel, the coating film spirally winds onto the piston rod. It can package piston rods of any length and diameter within a certain range. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1 like Figure 1-8As shown, a piston rod feeding device includes a conveying mechanism 1, a detection mechanism 2, and a covering mechanism 3. The detection mechanism 2 and the covering mechanism 3 are arranged above the conveying mechanism 1. The conveying mechanism 1 includes a conveying frame 11, on which a tilting motor 6 and a conveying motor 5 are fixed. The output shaft of the tilting motor 6 is coaxially and fixedly connected to a connecting rod 13 rotatably connected to the conveying frame 11. A conveying screw 12 is sleeved on the connecting rod 13. The conveying screw 12 is connected to the conveying motor 5 through gear transmission. The side of the conveying screw 12 is provided with a deep spiral groove 121 and a shallow spiral groove 122 with opposite spiral directions. Two sliding rods 48 are provided on the conveying frame 11. The space between the two sliding rods 48 forms a groove 111. A slider 47 is slidably connected in the groove 111. The lower part of the slider 47 is inserted into the upper part of the sliding rod 48. The lower part of the sliding rod 48 slides in the deep spiral groove 121 and the shallow spiral groove 122 respectively. The rotating rod fixed on the upper part of the slider 47 slides in the rotating sleeve. The rotating sleeve is fixed below the directional gear 46. The directional gear 46 cooperates with the directional tooth surface 112 provided on the conveyor frame 11. The bracket 4 is fixedly connected above the directional gear 46. The flipping frame 14 is fixedly connected to both ends of the connecting rod 13 respectively. The flipping frame 14 is provided with a clamping plate 141. The clamping plate 141 cooperates with the clamping groove 471 on the side of the slider 47.

[0019] During conveying, the bracket 4 above the left end of the conveying screw 12 is perpendicular to the conveying screw 12. The surface-treated piston rod is placed parallel to the bracket 4 on the bracket 4. The conveying motor 5 rotates, driving the conveying screw 12 to rotate. The slide bar 48 is located in the deep spiral groove 121. The slider 47 in the groove 111, together with the bracket 4 connected above the slider 47, moves horizontally along the groove 111 as the conveying screw 12 rotates. When passing the adjusting tooth surface 112, the adjusting gear 46 rolls along the adjusting tooth surface 112, causing the bracket 4 and the piston rod it supports to rotate from a horizontal position to a vertical position. For longer piston rods, this can reduce the horizontal space occupied. Afterwards, the bracket 4 and the piston rod pass through the detection mechanism 2 and the coating mechanism 3 in sequence to complete the detection and coating. During the process, the piston rod only contacts the bracket 4, which can reduce contact and quickly complete the detection and coating, reducing damage to the piston rod. When the piston rod passes through the inspection mechanism 2, the surface damage is detected by the inspection camera 21, and the internal defects are detected by the ultrasonic probe 22. After inspection, the undamaged piston rod is packaged. When the slider 47 moves to the right end of the conveying screw 12, the groove 111 on the side of the slider 47 is inserted into the slider 47 on the side of the flipping frame 14. The flipping motor 6 runs to rotate the flipping frame 14 180°. During the flipping process, the packaged piston rod rolls off from one side of the conveying screw 12. A placement rack for receiving the piston rod can be set on this side. After the flipping frame 14 rotates 180°, the slide rod 48 inserted into the slider 47 slides into the slider 47 under the action of gravity. The slide rod 48 is adapted to the shallow spiral groove 122. The pressure roller 16 applies pressure to the slider 47 to the left under the pressure of the pressure cylinder 15. When the pressure on the side is applied, the conveying screw 12 rotates to the right end of the shallow spiral groove 122 and is opposite to the slide rod 48. The slide rod 48 slides into the shallow spiral groove 122. As the conveying screw 12 rotates, the slider 47 and the bracket 4 slide from right to left in the groove 111 below the conveying screw 12. When the directional gear 46 contacts the directional tooth surface 112 below, the bracket 4 rotates from longitudinal to transverse and then flips from the flipping frame 14 at the left end to above the conveying screw 12, and receives the piston rod after surface treatment again. The slide rod 48 slides down under the action of gravity and matches the deep spiral groove 121. Under the action of the pressure cylinder 15 and pressure wheel 16 set at the left end, the slider 47 is pushed into the upper groove 111 and the slide rod 48 is pushed into the deep spiral groove 121, and the piston rod is conveyed again. The deep spiral groove 121 and shallow spiral groove 122 on the side of the conveying screw 12 have opposite spiral directions and intersect. To prevent the slide rod 48 from entering the other spiral groove when passing through the intersection, the two sets of spiral grooves are arranged alternately with deep and shallow spiral grooves. The slide rod 48 is designed to be inserted into the end of the slider 47, so that it can adapt to the deep spiral groove 121 and shallow spiral groove 122 respectively when it is above or below the conveying screw 12. The rotating rod inside the rotating sleeve is connected to an elastic wear-resistant plate 472 to increase the friction between the rotating rod and the rotating sleeve, so as to prevent the bracket 4 from deflecting due to inertia during the adjustment process or from rotating relative to the slider 47 during the flipping process.

[0020] Example 2 like Figure 1-8As shown, a piston rod feeding device includes a conveying mechanism 1, a detection mechanism 2, and a covering mechanism 3. The detection mechanism 2 and the covering mechanism 3 are arranged above the conveying mechanism 1. The conveying mechanism 1 includes a conveying frame 11, on which a tilting motor 6 and a conveying motor 5 are fixed. The output shaft of the tilting motor 6 is coaxially and fixedly connected to a connecting rod 13 rotatably connected to the conveying frame 11. A conveying screw 12 is sleeved on the connecting rod 13. The conveying screw 12 is connected to the conveying motor 5 through gear transmission. The side of the conveying screw 12 is provided with a deep spiral groove 121 and a shallow spiral groove 122 with opposite spiral directions. Two sliding rods 48 are provided on the conveying frame 11. The space between the two sliding rods 48 forms a groove 111. A slider 47 is slidably connected in the groove 111. The lower part of the slider 47 is inserted into the upper part of the sliding rod 48. The lower part of the sliding rod 48 slides in the deep spiral groove 121 and the shallow spiral groove 122 respectively. The rotating rod fixed on the upper part of the slider 47 slides in the rotating sleeve. The rotating sleeve is fixed below the directional gear 46. The directional gear 46 cooperates with the directional tooth surface 112 provided on the conveyor frame 11. The bracket 4 is fixedly connected above the directional gear 46. The flipping frame 14 is fixedly connected to both ends of the connecting rod 13 respectively. The flipping frame 14 is provided with a clamping plate 141. The clamping plate 141 cooperates with the clamping groove 471 on the side of the slider 47.

[0021] The conveyor frame 11 is provided with a rotating toothed surface 113. A rotating gear 45, which meshes with the rotating toothed surface 113, is positioned above the support plate 41 of the bracket 4. The rotating gear 45 drives the rotating wheels 43. There are four rotating wheels 43, each wound with a rotating belt 44. The rotating wheels 43 are rotatably connected to V-shaped frames 42. The piston rod is placed on the V-shaped rotating belt 44, which can accommodate different types of piston rods and has a small contact area. Three V-shaped frames 42 are provided on the support plate 41, each connected to the rotating belt 44, to stably support the piston rod. When the bracket 4 passes the rotating toothed surface 113, the support plate 41... The rotating gear 45 connected to the upper rotating gear engages with the rotating tooth surface 113, and the rotating wheel 43, which is connected to the rotating gear 45, rotates accordingly. The rotating belt 44 on the rotating wheel 43 rotates, causing the piston rod to rotate. The bracket 4 rotates and translates with the rotating conveying screw 12, so that the piston rod moves and rotates while passing through the detection mechanism 2 and the covering mechanism 3. The detection mechanism 2 can perform comprehensive detection on the piston rod, and the covering mechanism 3 can cover the piston rod. During detection, the piston rod moves and rotates while passing through the detection camera 21 and the ultrasonic probe 22. The detection camera 21 can take pictures and detect the piston rod along the spiral surface.

[0022] Example 3 like Figure 1-8As shown, a piston rod feeding device includes a conveying mechanism 1, a detection mechanism 2, and a covering mechanism 3. The detection mechanism 2 and the covering mechanism 3 are arranged above the conveying mechanism 1. The conveying mechanism 1 includes a conveying frame 11, on which a tilting motor 6 and a conveying motor 5 are fixed. The output shaft of the tilting motor 6 is coaxially and fixedly connected to a connecting rod 13 rotatably connected to the conveying frame 11. A conveying screw 12 is sleeved on the connecting rod 13. The conveying screw 12 is connected to the conveying motor 5 through gear transmission. The side of the conveying screw 12 is provided with a deep spiral groove 121 and a shallow spiral groove 122 with opposite spiral directions. Two sliding rods 48 are provided on the conveying frame 11. The space between the two sliding rods 48 forms a groove 111. A slider 47 is slidably connected in the groove 111. The lower part of the slider 47 is inserted into the upper part of the sliding rod 48. The lower part of the sliding rod 48 slides in the deep spiral groove 121 and the shallow spiral groove 122 respectively. The rotating rod fixed on the upper part of the slider 47 slides in the rotating sleeve. The rotating sleeve is fixed below the directional gear 46. The directional gear 46 cooperates with the directional tooth surface 112 provided on the conveyor frame 11. The bracket 4 is fixedly connected above the directional gear 46. The flipping frame 14 is fixedly connected to both ends of the connecting rod 13 respectively. The flipping frame 14 is provided with a clamping plate 141. The clamping plate 141 cooperates with the clamping groove 471 on the side of the slider 47.

[0023] The coating mechanism 3 includes a lifting frame 31 connected above the conveyor frame 11 via a lifting cylinder 37. An unwinding drum 32 for holding the coating film roll is mounted on the lifting frame 31. One end of the unwinding drum 32 is coaxially fixed to the output shaft of the unwinding motor. A coating wheel 33 is positioned below the unwinding drum 32, and a clamping and cutting tool 34 is mounted on the side of the coating wheel 33. The clamping and cutting tool 34 includes a clamping blade 342 and a shearing blade 341 rotatably connected to the lifting frame 31. The inner arc surface of the clamping blade 342 and the outer arc surface of the shearing blade 341 form a clamping part. The cutting blade 341 is used to clamp the coating film. The cutting edge of the shearing blade 341 cooperates with the cutting plate 343 fixed to the end of the clamping blade 342 to cut the coating film. The ends of the shearing blade 341 and the clamping blade 342 are connected by a torsion spring, so that the two blades are separated without pressure. A shearing cylinder 35 is fixed on the lifting frame 31. The shearing cylinder 35 is arc-shaped with the axis of the coating wheel 33 as the center. The piston in the shearing cylinder is fixed to the shearing blade 341. A baffle 36 is provided on the lifting frame 31 to abut against the side of the clamping blade 342.

[0024] Before coating, the coating film passes under the coating wheel 33 and through the gap between the clamping blade 342 and the shearing blade 341. The clamping part of the shearing blade 341 and the clamping blade 342 holds the coating film. The lifting frame 31 moves down until the coating wheel 33 is in contact with the piston rod to be coated. The piston of the shearing cylinder 35 retracts, the clamping cutter 34 releases its grip, and the unwinding motor drives the unwinding drum 32 to rotate, continuously unwinding the coating film. The piston rod moves and rotates at the same time, so that the coating film spirally winds around the piston rod. This method is applicable to piston rods of different lengths and diameters. After coating is completed, the lifting frame 31 is slightly raised, the piston of the shearing cylinder 35 extends, and pressure is applied to the shearing blade 341. The shearing blade 341 approaches the clamping blade 342, the clamping part holds the coating film, and the blade and the cutting plate 343 cut the coating film. When the next piston rod passes, the coating is repeated, which can achieve continuous coating.
