Description

Technical Field

[0001] The invention relates to the field of pipe joint production, and in particular to a hydraulic pipe joint feeding device. Background Art

[0002] The function of the hydraulic system is to increase the force by changing the pressure. The hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. The hydraulic transmission system mainly transmits power and motion. The hydraulic control system must make the hydraulic system output meet specific performance requirements (especially dynamic performance). The hydraulic system usually refers to the hydraulic transmission system. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil.

[0003] Hydraulic pipe fittings are components that connect high-pressure oil pipes to high-pressure oil pipes in hydraulic systems. Hydraulic pipe fittings can be divided into hydraulic hoses, high-pressure ball valves, quick connectors, ferrule-type pipe fittings, welding-type pipe fittings, high-pressure hoses, transition-type pipe fittings, ferrule-type pipe fittings, three-way pipe fittings, non-standard pipe fittings, flared pipe fittings, right-angle pipe fittings, rotary pipe fittings, quick connectors, stainless steel pipe fittings, and copper fittings. When processing hydraulic pipe fittings one by one in the workshop, all pipe fitting parts need to be stacked one by one on the conveyor belt for transportation, so that all pipe fitting parts can be sent to the processing procedure one by one for processing. Before entering the processing procedure, the parts need to be transported to the processing procedure one by one for processing, and the traditional conveyor belt can only be used for batch transportation. Therefore, it is necessary to design an efficient feeding device that can feed pipe fittings one by one. Summary of the invention

Then the first cylinder 4 is activated to drive the L-shaped push plate 5 to push in a direction perpendicular to the conveyor belt 2, thereby pushing the pipe joint stopped by the L-shaped baffle 6 into the material transfer channel 7.

[0032] A downwardly concave material trough 13 is provided at the top of the material transfer channel 7, and the length direction of the material trough 13 is parallel to the length direction of the conveyor belt 2.

[0033] A horizontal strip hole 17 is provided on the long plate of the L-shaped baffle 6, and the L-shaped baffle 6 is fixedly connected to the long plate of the L-shaped push plate 5 by two bolts passing through the strip hole 17. The strip hole 17 cooperates with the bolts to adjust the installation position of the L-shaped baffle 6 on the L-shaped push plate 5, thereby adjusting the distance between the short plate of the L-shaped baffle 6 and the end of the side support plate 11.

[0034] The bottom of the trough 13 is provided with a plurality of circular leak holes 18, and the bottom of the material transfer channel 7 is provided with a rectangular leak hole 19, all of which are located directly below the rectangular leak holes 19. A receiving basin 20 is provided directly below the material transfer channel 7, and the receiving basin 20 is located directly below the rectangular leak holes 19. The circular leak holes 18 at the bottom of the trough 13 are used to allow impurities such as scraps on the parts that are easy to fall off to fall down, and fall into the receiving basin 20 below through the rectangular through holes for collection.

[0035] A counting sensor 21 is provided at the top of the middle section of the side support frame 10, and the detection end of the counting sensor 21 extends obliquely downward to just above the conveyor belt 2.

[0036] The material stopping mechanism includes a resistance rod 22, a material stopping plate 23 and a tension spring 24. The resistance rod 22 is arranged at the top of the short plate of the L-shaped pushing plate 5, and the length direction of the resistance rod 22 is perpendicular to the length direction of the conveyor belt 2. The end of the material stopping plate 23 away from the resistance rod 22 is hinged to the inner wall of the side support plate 11, and one end of the tension spring 24 is fixedly arranged on the side support plate 11, and the other end of the tension spring 24 is fixedly connected to the end of the material stopping plate 23 away from the resistance rod 22.

Before the first cylinder 4 pushes the intercepted pipe joint into the material transfer channel 7, the tension spring 24 pulls the end of the stop plate 23 close to the starting end of the conveyor belt 2, so that the other end of the stop plate 23 is pried toward the inside of the conveyor belt 2 under the action of the hinge shaft 28, and then the rear pipe joint is intercepted on the conveyor belt 2 to prevent it from continuing to move forward. By setting a resistance rod 22 at the top of the L-shaped pushing plate 5, and then when the first cylinder 4 is extended, the resistance rod 22 is driven to move forward and resist the stop plate 23, so that the pipe joint intercepted at the rear can continue to move forward, so that every time a pipe joint is pushed into the material transfer channel 7, a pipe joint at the rear continues to move forward. Finally, when the L-shaped baffle 6 returns to its position with the first cylinder 4, the pipe joint at the rear just moves forward a distance until it is intercepted by the L-shaped baffle 6, so that the pipe joints on the conveyor belt 2 are pushed one by one into the material transfer channel 7 and then sent away by the push rod 9.

The block 32 is clamped on the top of the L-shaped push plate 5 and can be adjusted on the short side according to actual working conditions.

[0038] The feeding mechanism 3 includes a material box 34, a box frame 35, a first material ejector plate 36 and a second material ejector plate 37. The material box 34 is vertically arranged on the top of the box frame 35. The first material ejector plate 36 and the second material ejector plate 37 are both in a vertical state and are arranged at intervals in the horizontal direction. The first material ejector plate 36 and the second material ejector plate 37 extend from the bottom of the material box 34 to the inside of the material box 34 from bottom to top. A lifting plate 38 is horizontally arranged directly below the material box 34. The first material ejector plate 36 and the second material ejector plate 37 are arranged at intervals on the top of the lifting plate 38. A third cylinder 39 is provided directly below for driving the lifting plate 38 to move up and down. A lower partition 40 is vertically provided inside the material box 34 for separating the first ejector plate 36 and the second ejector plate 37. The top of the lower partition 40, the top of the first ejector plate 36, the top of the second ejector plate 37 and the top extension of the material box 34 are all inclined structures with the same slope. The height difference between the top of the material box 34 and the top of the lower partition 40, and the height difference between the top of the first ejector plate 36 and the top of the second ejector plate 37 are equal to the stroke of the third cylinder 39. The pipe joint parts are transported to the conveyor belt 2 by the feeding mechanism 3 at the beginning of the conveyor belt 2 for transmission.

[0039] The upper half of the material box 34 has a larger diameter than the lower half, and the upper half of the material box 34 is divided into a storage bin 52 and a feed bin 42 by an upper partition 41. The bottom of the feed bin 42 is provided with a first inclined plate 43 extending to the middle of the inner side of the bin, and the top of the partition is provided with a second inclined plate 44. A third inclined plate 45 is provided at the end of the top of the material box 34 away from the feed bin 42, a fourth inclined plate 46 is provided at the top of the first top plate 36, and a fifth inclined plate 47 is provided at the top of the second top plate 37. The first inclined plate 43 and the second inclined plate 44 are provided at the top of the material box 34. The inclinations of the third inclined plate 44, the fourth inclined plate 46 and the fifth inclined plate 47 are the same and the lower ends of the five are inclined toward a direction away from the feed bin 42. The height difference between the first inclined plate 43 and the second inclined plate 44, the height difference between the second inclined plate 44 and the third inclined plate 45, and the height between the fourth inclined plate 46 and the fifth inclined plate 47 are all equal to the stroke of the third cylinder 39. The distance between the bottom of the upper partition 41 and the bottom of the feed bin 42 is greater than the diameter of the pipe joint, and the lower end of the third inclined plate 45 is flush with the top of the conveyor belt 2. The pipe fitting parts are manually poured into the feed bin 42, and the pipe fitting at the bottom of the feed bin 42 slides onto the fifth inclined plate 47 through the first inclined plate 43. Then the third cylinder 39 is actuated to drive the lifting plate 38 to rise, thereby driving the first ejecting plate 36 and the second ejecting plate 37 to rise at the same time. When the pipe fitting on the fifth inclined plate 47 is lifted to the highest point, it slides onto the second inclined plate 44, and further slides onto the fourth inclined plate 46. With the next action of the third cylinder 39, the pipe fitting on the fourth inclined plate 46 further slides onto the third inclined plate 45 at the highest point, and finally slides onto the conveyor belt 2 for transportation.

[0040] A return chute 48 in an inclined state is provided on one side of the top of the material box 34. The upper end of the return chute 48 is connected to the top of the transmission belt, and the lower end of the return chute 48 is connected to the feed bin 42. The return chute 48 is located on the side of the material box 34 close to the end of the conveyor belt 2. The minimum distance between the upper end of the return chute 48 and the side support frame 10 is less than half the length of the pipe joint. When the pipe joint is transported on the conveyor belt 2 and passes through the return chute 48, if a pipe joint perpendicular to the conveyor belt 2 passes through, since the minimum distance between the upper end of the return chute 48 and the side support frame 10 is less than half the length of the pipe joint, the pipe joint with the wrong posture will fall into the return chute 48 under the action of its own gravity, and return to the feed bin 42 to be reloaded, thereby ensuring that the posture of the pipe joint transported to the end of the conveyor belt 2 is parallel to the conveyor belt 2.

[0041] A rectangular mounting frame 49 is provided on the top of the box frame 35, and the rectangular mounting frame 49 is fixedly sleeved on the outer side of the lower half of the material box 34. The third cylinder 39 is vertically provided on the lower half of the box frame 35, and the output shaft of the third cylinder 39 is vertically upward and fixedly connected to the bottom of the lifting plate 38. The third cylinder 39 is used to push the lifting plate 38 to move up and down.

[0042] The two sides of the upper partition 41 are respectively fitted with the first and second ejector plates 36 and 37, and the widths of the first, second, third, fourth, and fifth inclined plates 43, 44, 45, 46, and 47 in the horizontal direction are all greater than the diameter of the pipe joints, ensuring that the pipe joints can be transported upward one by one without falling.

[0043] The bottom of the material box 34 is provided with two parallel strip-shaped avoidance holes for the first and second ejector plates 36 and 37 to pass through, and the lower ends of the first inclined plate 43, the second inclined plate 44, the third inclined plate 45, the fourth inclined plate 46 and the fifth inclined plate 47 are integrally provided with an anti-stuck upper slide plate 50 extending vertically downward, and the bottom side of the first and second ejector plates 36 and 37 are integrally provided with an anti-stuck lower slide plate 51 extending vertically upward. The anti-stuck upper slide plate 50 and the anti-stuck lower slide plate 51 ensure that the first and second ejector plates 36 and 37 can slide up and down smoothly in the material box 34.

[0044] Working principle: pipe joint parts are manually poured into the feed bin 42, and the pipe joint at the bottom of the feed bin 42 slides onto the fifth inclined plate 47 through the first inclined plate 43, and then the third cylinder 39 is actuated to drive the lifting plate 38 to rise, thereby driving the first ejecting plate 36 and the second ejecting plate 37 to rise at the same time, so that when the pipe joint on the fifth inclined plate 47 is lifted to the highest point, it slides onto the second inclined plate 44, and further slides onto the fourth inclined plate 46. With the next action of the third cylinder 39, the pipe joint on the fourth inclined plate 46 further slides onto the third inclined plate 45 at the highest point, and finally slides onto the conveyor belt 2 for transportation. When the pipe joint is transported on the conveyor belt 2 and passes through the return chute 48, if a pipe joint perpendicular to the conveyor belt 2 passes by, the minimum distance between the upper end of the return chute 48 and the side support frame 10 is smaller than The pipe joint is one-half the length of the pipe joint, so the pipe joint with the wrong posture will fall into the return chute 48 under the action of its own gravity, and return to the feed bin 42 for re-loading, so as to ensure that the posture of the pipe joint transported to the end of the conveyor belt 2 is parallel to the conveyor belt 2. When the pipe joint parts are transported to the end through the conveyor belt 2, they are blocked by the short plate of the L-shaped baffle 6 and stop moving forward. Then the first cylinder 4 is actuated to drive the L-shaped push plate 5 to push in a direction perpendicular to the conveyor belt 2, and then the pipe joint stopped by the L-shaped baffle 6 is pushed into the material transfer channel 7. The second cylinder 8 is actuated to drive the push rod 9 to move horizontally, so that the push rod 9 pushes the pipe joint in the material trough 13 to the end of the material transfer channel 7 to enter the subsequent processing technology. The circular leakage hole 18 at the bottom of the material trough 13 is used for the waste chips and other impurities that are easy to fall off on the parts to fall down, and fall into the receiving basin 20 below through the rectangular through hole for collection.

[0045] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
