[0047] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0048] As attached Figure 1 As shown, the hose support installation tool described in this embodiment mainly comprises a horizontally arranged workbench 1, a feeding device 2, a flaring device 3, a double-arm material taking and clamping device 4 and a buckling device 5;

[0049] The feeding device 2 is fixedly mounted on one end of the inclined bracket 11 of the workbench 1 through the material guide trough end plate 21; the expanding device 3 is fixedly mounted on the other end of the inclined bracket 11 through the pad 31, and is located on one side of the feeding device 2; the double-arm material picking and clamping device 4 is installed on the workbench 1 between the feeding device 2 and the buckling device 5; the double-arm material picking and clamping device 4 is provided with an integral swing device 42 that can rotate 180 degrees; the buckling device 5 is fixedly set on the workbench 1 through a small base 51; the feeding device 2 is used for a tooling conveying bracket 6, and the bracket 6 is arc-shaped, with a bending edge at one end and a buckle plate 61 at the other end.

[0050] For details, the structure of the bracket 6 is shown in the attached Fig. 9 To improve installation efficiency, when installing the bracket, you need to first expand the bracket opening 62, insert the expanded opening into the appropriate position on the hose (the position has been pre-installed with a retainer), then press the bracket opening 62 to close it, and bend the gusset plate 61 to fix it (see attached Fig.10 ) (Brake hoses are not necessarily straight, most are bent, and it is not very convenient to insert the bracket from the end).

[0051] The workbench 1 is arranged horizontally, and an inclined bracket 1 is arranged on the table surface at one end of the workbench, and the angle between the table surface of the inclined bracket 1 and the workbench surface is 30 degrees (preferably between 30 degrees and 60 degrees).

[0052] The feeding device 2 is fixedly mounted on the inclined bracket 1 through the guide trough end plate 21 (see attached Figure 1 and attached Figure 2 ).

[0053] The guide trough 22 is an open curved plate. Its inner contour matches the outer shape of the bracket 6. A guide plate 23 is provided on one side of the guide trough 22, and the bent edge of the bracket 6 fits the guide plate 23. The bracket 6 can slide freely downward along the guide trough 22 and the guide plate 23 in sequence under the action of gravity.

[0054] At the lower position of the guide trough 22, the lower end of the guide plate 23 is vertically fixed with a guide trough end plate 21. The lower end of the guide trough 22 is not directly connected to the end plate 21, and a space needs to be reserved for the clamping claw of the clamping claw mechanism to extend into the lower end of the guide trough 22 to receive the material (grab the bracket). The distance between the lower end of the guide trough 22 and the end plate 21 corresponds to the width of the bracket 6. The guide trough 22 and the end plate 21 can be connected on the premise of leaving the material receiving space of the clamping claw mechanism.

[0055] At the lower end of the guide groove 22 (the upper end of the inserted clamping claw) at a position twice the width of the bracket, a stop column 24 is suspended, the diameter of which is larger than the bracket inner ring 63 before expansion and slightly smaller than the bracket inner ring 63 after expansion. The bracket without expansion is blocked by the stop column 24 and cannot slide down, while the bracket after expansion can slide down freely into the clamping claw. The stop column 24 is fixedly connected to the guide plate 23 through the stop column fixing arm 241.

[0056] At a position where the lower end of the material guide groove 22 (the upper end of the inserted clamping claw) is twice the width of the bracket, there is an open space above the material guide groove 22, which is convenient for expanding the opening of the bracket upward, and the inner circle diameter of the bracket increases accordingly. A back plate 25 is fixed on the rear side of the open space to limit the position of the bracket.

[0057] The upper left end of the stopper 24 is the expansion station of the bracket. Because there is an open space above the guide slot 22 at the expansion station, the guiding effect of the bracket is poor, and a guide plate 26 is added at the position of the guide plate 23. It does not affect the expansion of the bracket.

[0058] Because the width of the bracket at the position of the buckle plate 61 on the bracket is slightly larger, in order to ensure that the bracket is positioned correctly after sliding into the clamping claw, a cushion block 27 is provided on the end plate 21 at the narrow side of the bracket.

[0059] When the clamping jaws are extended into the material taking station, the movable clamping jaws 472 are in an open state. The inner profile surface of the fixed clamping jaws 471 is in contact with the inner guide surface of the material guide groove 22 and the material guide plate 23.

[0060] The expansion device 3 is fixedly mounted on the inclined bracket 11 through a pad 31 and is located outside the feeding device 2.

[0061] The expansion device 3 includes a pair of expansion forks, a forward pushing device, a movable fork opening and closing control device, etc. (see attached Figure 3 ).

[0062] The forward push device includes a forward push cylinder fixing frame 32, a forward push cylinder 33, a guide rail pair 34, etc.

[0063] The forward cylinder 33 is fixedly mounted on the backing plate 31 through the fixing frame 32. The guide rail of the guide rail pair 34 is fixedly arranged on the backing plate 31, located at the front end of the forward cylinder 33, and in the same direction as the piston rod. The flared fork support seat 35 is fixed to the slider 342 and fixedly connected to the piston rod end of the forward cylinder.

[0064] The rear end of the fixed fork 36 is fixedly connected to the flared fork support seat 35, and the direction of the fixed fork is the same as that of the guide rail. The rear end of the movable fork 37 is hingedly connected to the fork tail hinge support 361 fixedly provided at the rear end of the fixed fork 36.

[0065] The expansion cylinder 38 is hingedly mounted below the middle position of the fixed fork 36 through the mounting seat 381. The expansion cylinder piston rod 382 passes through the fixed fork 36 and is hingedly connected to the middle position of the movable fork 37.

[0066] The width of the front end 371 of the movable fork matches the notch of the front end 363 of the fixed fork. The expansion cylinder piston rod 382 retracts, the front end of the movable fork 37 engages with the front end groove of the fixed fork 36 (the whole becomes thinner to facilitate the deep penetration of the bracket opening), the expansion cylinder piston rod 382 pushes out, the front end of the movable fork 37 separates from the fixed fork, and the bracket opening is expanded to facilitate the bracket to be clamped into the hose.

[0067] The limit frame 39 is sleeved on the expansion fork and fixed to the fixed fork 36. An adjustment screw is provided on the limit frame 39 to control the opening distance of the expansion fork so as to control the size of the bracket opening.

[0068] The expansion device operates as follows: initially, the expansion cylinder piston rod 382 is in a retracted state, and the front end of the movable fork is engaged with the front end of the fixed fork; the piston rod of the forward-pushing cylinder 33 is pushed out, the expansion fork support seat 35 moves forward along the guide rail, and the expansion fork is inserted into the bracket opening; the expansion cylinder piston rod 382 is pushed out, and the front end of the movable fork 37 is separated from the fixed fork to expand the bracket opening; the expansion cylinder piston rod 382 is retracted, and the piston rod of the forward-pushing cylinder 33 is retracted. The expanded bracket slides down along the stop column 24, and the upper bracket moves down to the station to be expanded in turn, and so on.

A connecting piece 424 is fixedly provided at the top of the vertical shaft 421, and the main support seat 43 is plugged and installed with the connecting piece 424 through the plug connector 432 fixedly provided below.

[0073] The two grabbing devices are arranged in parallel and in opposite directions above the main support seat 43 .

[0074] The axis of the clamping jaw swing cylinder 44 is horizontal and fixed to the main support plate 431 through a swing cylinder support 433. The swing shaft of the clamping jaw swing cylinder 44 passes through the support 433. The end of the arm telescopic cylinder 45 is coaxially fixedly connected to a flange 441 fixedly provided at the end of the swing shaft. The swing shaft of the clamping jaw swing cylinder 44 can drive the arm telescopic cylinder as a whole to swing 60 degrees.

[0075] In order to ensure that the piston rod of the arm telescopic cylinder 45 is stable in direction and does not rotate during repeated movements, a piston rod guide device is provided at the outer end of the arm telescopic cylinder 45. The piston rod guide device includes a guide sleeve fixing plate 451, a clamping device fixing plate 452, a guide sleeve 453, and a guide rod 454 (see attached Figure 6 ).

[0076] The guide sleeve fixing plate 451 is fixedly mounted on the outer end of the arm telescopic cylinder 45, the outer end of the piston rod of the arm telescopic cylinder 45 is vertically fixedly mounted with the clamping device fixing plate 452, and the guide sleeve 453 is fixed to the guide sleeve fixing plate 451.

[0077] A gripping device (grip opening and closing cylinder 46 and gripping claw 47) is provided at the outer end of the clamping device fixing plate 452 (see attached Figure 4 and attached Figure 7 ).

[0078] The front cylinder cover 461 , the cylinder barrel, and the rear end cover 462 of the clamping jaw opening and closing cylinder 46 are fixedly connected by tie rod bolts and fixedly connected to the outer end of the clamping device fixing plate 452 .

[0079] The hollow piston rod (piston tube) 463 is slidably sleeved on the outer cylindrical surface of the fixed rod 465.

The inner end of the hollow piston rod (piston tube) 463 is fixed with a piston 464, and the outer end of the hollow piston rod (piston tube) 463 is provided with a hinge support 466.

[0080] The right end of the fixing rod 465 passes through the piston 464 and is fixedly connected to the rear end cover 462 .

[0081] The clamping jaw 47 is composed of a fixed clamping jaw 471 and a movable clamping jaw 472 which are hingedly connected.

[0082] The rear end of the fixed clamping claw 471 is fixedly connected to the front end of the fixed rod 465. The inner profile 4711 of the fixed claw is connected to the bracket 6 (see attached Fig. 9 ) The long plate bending surface of the upper half and the expanded outer cylindrical surface (63) match.

[0084] The pressing device 5 is fixedly arranged at the other end of the workbench 1 via a small base 51 .

[0085] As attached Figure 8As shown, the finger cylinder 53 is fixedly arranged on the small base 51, and a pressing finger support 54 is fixedly and symmetrically arranged on the parallel slide of the finger cylinder. A pair of U-shaped pressing jaws are fixedly and symmetrically arranged on the inner side of the pressing finger support, and the notches of the pair of U-shaped pressing jaws are opposite.

The pair of supporting fingers 55 located on the lower side are used to support the lower jaw 4723 of the movable clamp, bear the downward force when the pressing fingers 56 bend the buckle plate, and ensure the stability of the position of the clamp and the bracket.

[0086] The positioning blocks 52 are fixedly arranged on the small base 51 and are located at both ends of the finger cylinder, and are used to position the hose of the bracket to be installed.

[0087] When the present embodiment is working, the preparation work is firstly carried out: the brackets are fed into the guide trough 22 in parallel (an auxiliary device can be designed to automatically discharge the disordered brackets and feed them into the trough).

[0088] Before the bracket in the guide trough 22 is expanded, it is blocked by the stopper 24 and cannot move downward;

[0089] Secondly, the expanding device is actuated: initially, the expanding cylinder piston rod 382 is in a retracted state, and the front end of the movable fork is engaged with the front end of the fixed fork; the piston rod of the forward-pushing cylinder 33 is pushed out, the expanding fork support seat 35 moves forward along the guide rail direction, and the expanding fork is inserted into the bracket opening; the expanding cylinder piston rod 382 is pushed out, and the front end of the movable fork 37 is separated from the fixed fork to expand the bracket opening; the expanding cylinder piston rod 382 is retracted, and the piston rod of the forward-pushing cylinder 33 is retracted.

[0090] The bracket after the expansion slides down along the stop column 24 and falls into the open clamping claw 47 of the material taking station on the double-arm mounting device. The bracket above moves down to the expansion station in turn, and continues like this.

[0091] The negative pressure chamber 4712 of the clamping jaws at the material taking station at the lower end of the material guide trough is connected to the vacuum pump, and the bracket is sucked and fixed by the fixed clamping jaws.

[0092] While the clamping jaws at the material taking station are taking materials, the clamping jaws and the crimping device 5 at the crimping station are working synchronously.

[0093] The piston rods of the two sets of arm telescopic cylinders 45 are retracted synchronously;

[0094] The vertical axis of the main swing cylinder 426 rotates 180 degrees in the positive direction, and the two arms turn around synchronously: the clamping claw at the material picking station turns to the direction of the crimping station, and the other clamping claw at the crimping station turns to the direction of the material picking station. During this rotation process, the swing axes of the two clamping claw swing cylinders 44 drive the arm telescopic cylinder to rotate 60 degrees in the positive direction as a whole, so that the directions of the clamping claws at both ends match the working directions of their respective corresponding stations.

[0095] The piston rods of the two sets of arm telescopic cylinders 45 are extended synchronously, and the two sets of clamping jaws are respectively in place.

[0096] The movable clamping claw 472 of the pressing station is closed, the bracket opening is completely closed, and the movable clamping claw lower jaw 4723 reaches a horizontal position.

[0097] The crimping device works: the finger cylinder moves centripetally parallel to the slide table, the U-shaped crimping pliers move centripetally, the pair of supporting fingers 55 located below hold the lower jaw 4723 of the movable clamp, and the pair of pressing fingers 56 located above bend the buckle plate 61 inwardly. The finger cylinder moves outward parallel to the slide table and resets.

[0098] The movable clamping jaw 472 located at the crimping station is opened, and at the same time, the negative pressure chamber 4712 of the crimping station is connected to the atmosphere.

[0099] The piston rods of the two sets of arm telescopic cylinders 45 are retracted synchronously;

[0100] Remove the hose with the bracket installed, and put the hose to be installed with the retaining ring installed in place (it can be transported to the place with the help of a robotic arm).

[0101] The vertical axis of the main swing cylinder 426 rotates 180 degrees in the opposite direction, and the two arms turn around synchronously: the clamping claw of the crimping station turns to the direction of the material picking station, and the clamping claw of the material picking station turns to the direction of the crimping station.
