Description

Technical Field

[0001] The invention relates to the technical field of automobile parts production, in particular to a device for adjusting the direction of an opening guard ring to be consistent. Background Art

[0002] The annual sales volume of automobiles is quite large, and the production tasks of various automobile parts that match them are also extremely heavy. Among them, brake hoses and assemblies, brake hard pipe assemblies are extremely important parts on automobiles, with many specifications and types, and heavy component installation tasks. Installing guards and brackets on brake hoses is one of the processes for installing brake hose assemblies (there are also installations of other parts such as quick plugs and clamps). In conventional production, the open guard ring and bracket are manually put on the appropriate position of the hose, and then the bracket is pressed and the bracket is bent by the tooling. The installation efficiency of the bracket is low, and it is necessary to consider the realization of automated assembly. The first step to be solved is to determine the opening direction of the open guard ring to facilitate the mechanical gripper to grab and smoothly insert it into the appropriate position of the hose.

DETAILED DESCRIPTION

[0020] The tensioning device 2 comprises an elastic sleeve 21, a push rod 22, a cone 23, a first electromagnet 24, a push rod spring 241, a sleeve 25, an elastic ring 26 and a washer 27; the push rod 22 is coaxially slidably arranged at the center of the elastic sleeve 21 and the rotating sleeve 31, a cone 23 is provided at the top end of the push rod 22, and is connected to the iron core of the first electromagnet 24 at the lower end of the push rod 22, the first electromagnet 24 is fixedly installed below the base plate through the first bracket 11, the iron core of the first electromagnet 24 pushes the push rod 22 to move upward, the cone 23 makes the elastic sleeve 21 expand, and supports the retaining ring 6 from the inner side of the opening; the iron core of the first electromagnet 24 moves downward, the push rod 22 moves downward and resets, the elastic sleeve 21 shrinks and resets under elasticity, an elastic ring 26 is sleeved on the outer side of the middle part of the elastic sleeve 21 to increase the elastic contraction of the elastic sleeve inward, and a guide cone 212 is provided on the top of the elastic sleeve 21. A sleeve 25 is fixedly mounted around the lower section of the elastic sleeve 21 to limit excessive expansion of the elastic sleeve 21 . A washer 27 is disposed on the top of the sleeve 25 and the elastic ring 26 to axially limit the position of the opening retainer 6 .

[0021] Long grooves are evenly distributed around the periphery of the elastic sleeve 21 , and the height of the grooves is approximately twice the height of the opening retaining ring, so as to improve the flexibility of the elastic sleeve 21 .

[0022] The rotating device 3 includes a rotating sleeve 31, a bearing seat 32, a bearing 33, a second pulley 34, a belt 35, a second pulley 36 and a micro motor 37; the rotating sleeve 31 vertically passes through the through hole on the base plate, and is rotatably connected to the base plate through the bearing 33 and the bearing seat 32. The second pulley 34 is fixedly provided at the lower section of the rotating sleeve 31, and a micro motor 37 is provided on one side of the bearing seat 32. A first pulley 36 is fixedly provided on the output shaft of the micro motor 37. The micro motor 37 drives the rotating sleeve 31 to rotate through the first pulley 36, the belt 35 and the second pulley 34.

[0023] The circumferential positioning device 4 includes a second electromagnet 41, an insert plate 42 and a guide plate 43; the insert plate 42 is provided at the end of the core of the second electromagnet 41, and the insert plate 42 is guided by the guide plate 43 fixedly arranged on the second bracket 12, and the insert plate 42 moves radially along the opening guard ring 6 until it is inserted into the notch 61 of the opening guard ring.

[0024] The circumferential positioning device 4 is further provided with a limit pin 44 located at the end of the insert plate 42 for limiting the insert plate 42 from being inserted too deeply into the notch 61 of the retainer 6 to avoid being mistakenly inserted into the long groove of the elastic sleeve 21 .

[0025] The guide cylinder 5 is fixedly connected to the base plate through the support column 13 and the guide cylinder bottom plate 52 .

[0026] The opening guard ring 6 is coaxially arranged and slidably arranged in sequence in the material guide barrel, and the direction of the notch 61 of the opening guard ring 6 is in a disordered state. The second electromagnet 41 of the circumferential positioning device loses power, and the plug plate 42 retracts; the first electromagnet 24 of the tensioning device 2 loses power, the push rod 22 moves downward, and the elastic sleeve 21 is in a contracted state. The opening guard ring 6 in the material guide barrel moves downward, and the lowermost opening guard ring is introduced by the cone 23, sleeved on the outside of the elastic sleeve 21, and the lower end is limited by the gasket 27. The first electromagnet 24 of the tensioning device 2 is energized, the push rod 22 moves upward, and the elastic sleeve 21 expands slightly to support the inner wall of the opening guard ring. (Since the opening guard ring has a notch and is highly flexible, the expansion diameter of the elastic sleeve must be limited by the inner diameter of the sleeve 25 and the control of the iron core stroke of the first electromagnet to limit it). The second electromagnet 41 of the positioning device is energized, and the plug plate 42 moves forward radially under the thrust of the iron core. Since the notch of the opening guard ring 6 is generally not directly opposite the plug plate, the blade of the plug plate presses on the outer cylindrical surface of the opening guard ring 6. The current of the second electromagnet 41 should be limited, and the pressure of the plug plate should be small rather than large, otherwise the guard ring will be prevented from rotating. The micro motor 37 is energized to drive the tensioning device 2 to rotate slowly as a whole slightly more than one circle (such as 1.2∽1.5 circles). The opening guard ring rotates with the expansion force of the elastic sleeve 21. When the notch of the guard ring rotates to the position opposite to the plug plate, the plug plate is inserted into the notch, and the guard ring no longer rotates with the elastic sleeve. The micro motor 37 stops rotating; the second electromagnet 41 of the circumferential positioning device loses power, and the plug plate 42 retracts; the first electromagnet 24 of the tensioning device 2 loses power, the push rod 22 moves downward, and the elastic sleeve 21 is in a contracted state. The manipulator grabs and removes the opening guard ring 6 from the elastic sleeve. The opening guard ring 6 in the guide barrel moves downward, and the lowest opening guard ring is introduced by the cone 23, sleeved on the elastic sleeve 21, and the lower end is limited by the gasket 27, and the above action is repeated.
