Description

Feeding machine for screwed pipe fittings

Technical Field

The utility model relates to a loading attachment of pipe fitting, especially a material loading machine of silk grafting pipe fitting.

Background

The screw connection is also called as thread connection, and is a connection method used in pipelines such as water supply, heating, oil passages, compressed air and the like; threaded pipe elements are a generic term for threaded connecting elements. The screwed pipe fitting needs to be turned with inner threads or outer threads in the production process so as to facilitate connection. The threaded pipe fitting can be used independently, and can be matched with other structures to form connecting pipe fittings of other structures; for example, a movable joint, also called union, union or union, is a common pipeline connecting piece which can be conveniently installed and disassembled, and mainly comprises a nut, a cloud head and a butt joint; wherein the cloud head is also called as a thread section, which is a thread connecting pipe fitting.

The thread connecting pipe fitting needs to be machined through turning, tapping and the like in the production process, and the thread connecting pipe fitting needs to be installed on an upper part slide of machining equipment when the machining is carried out. When the processing equipment is used for processing, the threaded pipe fittings are required to be kept at the same posture for feeding, and therefore higher requirements are put on the feeding posture. At the present stage, two main modes are adopted for loading the upper scraper-trough conveyer into the wire connecting pipe fitting; one of the methods is a manual workpiece placing method, namely, each wire connecting pipe fitting is manually placed into an upper scraper-trough conveyer to ensure the feeding posture; although each operator can supplement the thread sections on the plurality of feeding chutes to keep the plurality of processing devices in normal operation, when one processing device breaks down, the operator needs to timely handle the fault and cannot place the thread receiving parts in other feeding chutes, so that other processing devices stop processing, the automation degree is low, a large amount of manpower and material resources are consumed, and the production efficiency is low. The other mode is a vibration disc feeding mode, namely disordered screw connecting pipe fittings are automatically, orderly, directionally and orderly arranged and accurately conveyed to a feeding chute through vibration, compared with the mode of manually placing the screw connecting pipe fittings, although the mode of vibration disc feeding is adopted, each operator can watch feeding of 2 to 3 processing devices, and when one processing device needs to be maintained, normal operation of other processing devices can be realized, but a large number of screw connecting pipe fittings are placed in each vibration disc during feeding of the vibration disc, so that not only can larger noise be generated in the vibration process, but also the appearance of the screw connecting pipe fittings can be influenced by collision.

Detailed Description

As shown in fig. 1 and 2, the feeding machine for the wire connecting pipe fitting comprises a material lifting mechanism, a linear feeding mechanism and a material clamping mechanism; the material lifting mechanism sends the screwed pipe fittings into the linear feeding mechanism, the linear feeding mechanism sends the screwed pipe fittings to the rear conveying end, and the material clamping mechanism clamps the screwed pipe fittings at the rear conveying end and sends the screwed pipe fittings to the material loading position of the next procedure. The material lifting mechanism, the linear feeding mechanism and the material clamping mechanism are all arranged on the supporting plate 1, and the supporting plate 1 is of a vertically arranged plate-shaped structure.

As shown in fig. 1, 2 and 3, the material lifting mechanism of the feeding machine for the wire connecting pipe fitting comprises a lifting hopper 22, a material blocking cylinder 23 and a material blocking plate 24. A vertical lifting slide way 26 is arranged at the front end of one vertical side surface of the supporting plate 1, a lifting slide block 25 is connected to the lifting slide way 26, and a lifting hopper 22 is fixedly connected to the lifting slide block 25, so that the lifting hopper 22 is vertically and slidably connected to the front end of the vertical side surface of the supporting plate 1; the lifting hopper 22 can be driven by an air cylinder or a motor to slide up and down. The lifting hopper 22 is of a hopper-shaped structure, the upper part of the lifting hopper and one side opposite to the support plate 1 are provided with openings, namely the feed opening is opposite to the support plate 1; the bottom surface of the lifting hopper 22 is obliquely and downwards inclined towards the direction of the supporting plate 1; thus, the threaded pipe fitting 5 in the lifting hopper 22 can slide to the position of the feed opening under the action of gravity, and the support plate 1 can block the feed opening, so that the threaded pipe fitting in the lifting hopper 22 can be prevented from falling down in the lifting process. The linear feeding mechanism comprises a feeding rail 31 and a vibrating feeder 32, and the feeding rail 31 is arranged on the other vertical side surface of the support plate 1. A material sliding baffle plate 21 is arranged on a supporting plate at the upper part of the feeding track 31; the sliding material baffle plate 21 is obliquely arranged, the upper end of the sliding material baffle plate 21 is over against the upper end of the supporting plate 1, and the lower end of the sliding material baffle plate 21 is over against the feeding track 31. The material slide baffle 21 includes a base plate 29 disposed obliquely and baffles 210 at the front and rear sides of the base plate to prevent the threaded pipe from falling off from both sides. The position of the upper end surface of the supporting plate 1 opposite to the lifting hopper 22 is obliquely arranged, and the structure is obliquely arranged downwards towards the direction of the feeding track 31. Thus, after the lifting hopper 22 is lifted to the upper end position of the supporting plate, the wire connecting pipe 5 therein slides downwards under the action of gravity, and because the inclined plate 27 and the upper end surface of the supporting plate at the position are designed to be inclined and the material sliding baffle 21 is arranged to be inclined, the wire connecting pipe 5 can slide to the material conveying track 31 along the inclined plate 27, the upper end surface of the supporting plate and the material sliding baffle 21. If a gap exists between the lifting hopper 22 and the sliding material baffle 21, an inclined plate 27 can be arranged above the supporting plate 1, and the inclined plate 27 is positioned between the gaps; the inclined plate 27 is obliquely arranged, the upper end of the inclined plate corresponds to the lower end of the feed opening after the lifting hopper 22 is lifted, and the lower end of the inclined plate corresponds to the upper part of the sliding material baffle plate 21; the inclined plate 27 is thus engaged between the lifting hopper 22 and the slip stop 21.

As shown in fig. 1, 2 and 3, the striker plate 24 of the material lifting mechanism of the feeding machine of the wire connecting pipe fitting is positioned above the sliding baffle 21 and can completely block the sliding baffle 21; the material blocking cylinder 23 is fixedly arranged on the support plate 1 through a fixing frame 28, and the output end of the material blocking cylinder 23 is downwards connected with the material blocking plate 24; therefore, after the material blocking cylinder 23 drives the material blocking plate 24 to rise, the material blocking plate 24 no longer blocks the material sliding baffle plate 21, and the wire connecting pipe can slide to the material conveying rail 31 along the material sliding baffle plate 21; after the material blocking cylinder 23 drives the material blocking plate 24 to descend, the material blocking plate 24 blocks the material sliding blocking plate 21, and the wire connecting pipe fitting is blocked and cannot slide down to the feeding rail 31.

As shown in fig. 1, 2 and 3, the linear feeding mechanism of the feeding machine for the screwed pipe fittings has a feeding track 31 extending horizontally from the front end of the supporting plate 1 to the rear end of the supporting plate; the vibrating feeder 32 is positioned below the feeding track 31; in this way, the feed rail 31 can feed the threaded pipe 5 to the rear end of the feed rail by the vibrating feeder 32. The feeding rail 31 is of a long groove strip structure, and the groove width is matched with the length between pipe orifices of the threaded pipe fitting 5; in this way, the pipe-connecting piece 5 can be transported in the feed rail 31 only in a position in which the nozzle plane is vertical. One side or two sides of the upper end of the feeding track 31 are provided with anti-falling baffles 33 for preventing conveyed screwed pipe fittings from falling; the feeding track 31 is not provided with the anti-falling baffle 33 at the position of the rear conveying end, so that the anti-falling baffle 33 is prevented from influencing the clamping mechanism to clamp the screwed pipe fitting 5. When the material lifting mechanism feeds materials by the linear feeding mechanism, the pipe orifice of the pipe connecting pipe 5 is contacted with the bottom surface of the material sliding baffle plate 21 in the sliding process because the pipe connecting pipe 5 slides downwards along the inclined bottom surface of the material sliding baffle plate 21; in the process that the lower end of the slip material baffle 21 falls to the feeding rail 31, the screw pipe fitting 5 forms a posture that the plane of the pipe orifice is vertical or inclined upwards, so that the pipe orifice can fall to the feeding rail 31 in the vertical posture.

As shown in fig. 1, 2, 4 and 5, the material clamping mechanism of the feeding machine for wire-connecting pipe fittings is arranged at the rear end of one side of the feeding rail 31 and comprises a horizontal slide 47, a connecting slide plate 49, a vertical slide 410, a feeding cylinder 42, a lifting cylinder 43, a rotating cylinder 44 and a clamping jaw cylinder 45. The horizontal slide way 47 is horizontally arranged on the fixing plate 41, and the fixing plate 41 is fixedly connected to the upper part of the supporting plate 1. The connecting slide plate 49 is vertically arranged and is connected to the horizontal slide way 47 in a sliding manner through a horizontal slide block 48. The feeding cylinder 42 is fixed on the fixing plate 41, and the output end of the feeding cylinder 42 horizontally extends out and is connected with the connecting sliding plate 49 or the horizontal sliding block 48; so that the feed cylinder 42 pushes the connecting slide plate 49 to slide in the horizontal direction. The vertical slide way 410 is vertically arranged on the connecting slide plate 49, and a vertical slide block 412 is connected to the vertical slide way 410 in a sliding manner; the rotary cylinder 44 is fixedly connected to the vertical slide block 412. The lifting cylinder 43 is fixed on the connecting sliding plate 49, and the output end of the lifting cylinder 43 extends downwards and is connected with the rotating cylinder 44 or the vertical sliding block 412; thus, the lifting cylinder 43 can push the rotating cylinder 44 to slide up and down along the vertical direction. The output end of the rotary cylinder 44 is downwards connected with the cylinder body of the clamping jaw cylinder 45; the jaws 46 of the jaw cylinder are disposed downwardly. The clamping jaws 46 of the clamping jaw air cylinder can move between the conveying rear end of the feeding track 31 and the loading position of the next process under the driving of the feeding air cylinder 42 and the lifting air cylinder 43. A direction sensor 411 is arranged on the clamping jaw 46 of the clamping mechanism; the direction sensors 411 are proximity switches, and are provided with two direction sensors and are respectively arranged on two claws of the clamping jaw 46; when the clamping jaw 46 clamps the wire connecting pipe fitting 5, the end face of one direction sensor, which is opposite to the large pipe orifice of the wire connecting pipe fitting, is not opposite to the end face of the small pipe orifice, and the end face of the other direction sensor, which is opposite to the small pipe orifice of the wire connecting pipe fitting, is not opposite to the end face of the large pipe orifice; therefore, the direction of the wire connecting pipe fitting 5 can be judged according to the triggering conditions of the two direction sensors. After the structure is adopted, the feeding cylinder 42 horizontally drives the clamping jaw 46 to move, and the lifting cylinder 43 drives the clamping jaw 46 to move up and down; after the clamping jaw 46 moves to the position of the conveying rear end of the feeding track 31, the clamping jaw cylinder 45 drives the clamping jaw to directly clamp the screw connecting pipe fitting 5 because the position of the conveying rear end of the feeding track 31 is not provided with the anti-falling baffle 33; then the feeding cylinder 42 and the lifting cylinder 43 are driven to move to the feeding position of the next procedure, and the clamping jaw cylinder 45 loosens the clamping jaw, so that the feeding of the next procedure can be realized; in the process of moving to the loading position of the next process, the rotary cylinder 44 rotates 180 degrees or does not rotate according to the direction of the wire connecting pipe judged by the direction sensor 411.

As shown in fig. 1-5, the feeding machine for the wire connecting pipe fitting adopts the following feeding steps: (1) The lifting hopper 22 is lowered to the lower portion of the supporting plate 1 to receive the feed of the previous process.

(2) The lifting hopper 22 moves upwards on the supporting plate 1 and drives the wire connecting pipe fitting therein to move upwards; until the inclined bottom end of the lifting hopper 22 is flush with the upper end of the supporting plate 1; at this time, since the bottom surface of the lifting hopper 22 is designed to be inclined, the wire connecting pipe 5 slides down to the position of the supporting plate 1, and is stopped by the striker plate 24 and stacked together.

(3) The material blocking cylinder 23 drives the material blocking plate 24 to rise upwards, and a channel capable of accommodating the passing of the wire connecting pipe fitting is formed below the material blocking plate 24; thus, part of the wire connecting pipe fittings can pass through the channel to enter the material sliding baffle 21 and slide to the conveying front end of the material conveying track 31 along the material sliding baffle 21; due to the limitation of the groove width of the feeding rail 31 and the posture adjustment in the sliding process, the screwed pipe fitting 5 on the feeding rail 31 is in a posture that the pipe orifice plane is vertical. The material blocking cylinder 23 is controlled to drive the material blocking plate 24 to rise or fall, and then the feeding speed of the material blocking rail 31 can be controlled.

(4) The threaded pipe on the feed rail 31 is fed to the rear end of the conveyance by the vibrating feeder 32. The vibratory feeder 32 stops operating.

(5) The clamping jaw air cylinder 45 drives the clamping jaw to clamp the screwed pipe fitting 5; then, the feeding cylinder 42 and the lifting cylinder 43 are driven to move to the material loading position of the next working procedure; in the moving process, the rotary cylinder 44 rotates 180 degrees or does not rotate according to the direction of the wire connecting pipe judged by the direction sensor 411; after moving to the loading position of the next process, the clamping jaw air cylinder 45 releases the clamping jaw, and the wire connecting pipe fitting 5 can be sent to the next process in a specific posture.

(6) The feeding cylinder 42 drives the clamping jaw 46 to move horizontally, the lifting cylinder 43 drives the clamping jaw 46 to move up and down, and the clamping jaw 46 moves to the position of the conveying rear end of the feeding track 31 under the driving of the feeding cylinder 42 and the lifting cylinder 43. The vibratory feeder 32 begins to operate.
