Abstract
Description
Technical Field
[0001] The utility model relates to a cover removing and installing mechanism for a bearing packaging barrel. Background Art
[0002] After the bearings are produced, they need to be packaged in a packaging barrel. The packaging barrel is generally made of soft plastic and has a certain degree of flexibility. The barrel containing the bearings consists of a barrel body and a barrel lid. In some packaging machines, the loading barrel is uncut, that is, the barrel body and barrel lid need to be cut in the packaging machine; while in other packaging machines, the loading barrel is already cut, and the barrel body and barrel lid are separate. However, when the packaging barrel is loaded, the barrel lid is placed on the barrel body during loading. Therefore, the packaging machine needs to remove the barrel lid from the barrel body before loading the bearings into the barrel body. However, in order to ensure that the barrel body is fully filled with bearings and the barrel lid is not easy to separate from the barrel body after it is covered, matching flanges and grooves, or an interference fit, are generally provided between the contact surfaces of the barrel lid and the barrel body. Although this structural setting can ensure that the barrel lid is not easy to fall off from the barrel body port, it will affect the lid removal and installation operations, making the barrel lid difficult to remove from the barrel body port or install on the barrel body port. Utility Model Content
[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a bearing packaging barrel cover removal and installation mechanism, which allows the barrel cover to be easily removed from the barrel body port or easily installed on the barrel body port.
[0004] In order to achieve the above purpose, one of the technical solutions adopted by the utility model is: a bearing packaging barrel cover removal and cover installation mechanism, including a frame, a barrel cover clamping assembly and a barrel body clamping assembly arranged on the frame, the barrel cover clamping assembly is driven by an X-axis linear module and moves back and forth in the X-axis direction, the barrel body clamping assembly is driven by a Y-axis linear module and moves back and forth in the Y-axis direction, a lifting assembly is arranged between the barrel cover clamping assembly and the barrel body clamping assembly, the lifting assembly includes a lifting rod and a lifting cylinder, the lifting cylinder drives the lifting rod to rise and fall, and the lifting rod can act on the circumferential deformation of the barrel body clamped by the barrel body clamping assembly.
[0005] Preferably, the bottom of the push rod is arc-shaped to prevent the push rod from damaging the barrel body.
[0006] Preferably, the width of the lower end of the ejector rod is smaller than the width of the upper end.
[0007] Preferably, the ejector rod is located above the clamped barrel, the ejector cylinder is fixed above the clamped barrel, the telescopic shaft of the ejector cylinder faces downward and is detachably connected to a connecting plate, and the ejector rod is detachably mounted on the connecting plate. Positioning the ejector rod above the barrel provides a more rational layout and can be embedded in existing packaging machines. The use of a connecting plate to detachably connect the ejector rod and the ejector cylinder facilitates replacement of ejector rods of different lengths.
[0008] Preferably, the barrel body clamping assembly includes a barrel body base and at least one barrel body clamping piece. The barrel body base is driven by the Y-axis linear module. The end surface of the barrel body base facing the barrel body clamping piece is provided with a first arc groove matching the barrel body. Each of the barrel body clamping pieces is driven to rise and fall by a barrel body cylinder.
[0009] Preferably, the barrel clamping member is offset from the barrel base at least at the end thereof that faces the ejecting rod. The barrel clamping member on the end that faces the ejecting rod covers a portion of the barrel base, and a clearance space is formed on the side of the barrel clamping member that faces the ejecting rod. When the ejecting rod is close to the clearance space, when the ejecting rod forces the barrel body to deform, the other portion of the barrel body is supported and fixed by the barrel base, thereby facilitating partial circumferential deformation of the barrel body.
[0010] Preferably, the barrel body also includes a barrel end clamping assembly, comprising a barrel body clamping cylinder, two rotating blocks, and two clamping plates. The barrel body clamping cylinder is fixed to one side of the barrel body base and drives the two rotating blocks to rotate toward or in opposite directions. The two clamping plates are respectively fixed to the rotating blocks, and the two clamping plates are each provided with a second arc-shaped groove on the facing side. When the ejector rod forces the barrel body to deform, the barrel body end clamping assembly further fixes and supports the barrel body, further facilitating the partial circumferential deformation of the barrel body.
[0011] Preferably, the bung cover clamping assembly includes a bung cover clamping cylinder, multiple clamping moving blocks, multiple bung cover clamps and a stepper motor. The bung cover clamping cylinder is arranged horizontally, and the multiple bung cover clamping moving blocks are arranged in a circle. The bung cover clamping cylinder drives the multiple bung cover clamping moving blocks to move back and forth toward and away from the center of the circle, and the stepper motor drives the bung cover clamping cylinder to rotate.
[0012] The beneficial effect of the present invention is that before removing or installing the lid, the lifting cylinder drives the lifting rod to rise and fall, thereby forcing the circumference of the barrel body clamped by the barrel body clamping assembly to deform. The originally circular barrel body is pushed to deform, but the barrel cover remains circular, so that a gap is formed on the contact surface where the barrel cover and the barrel body circumference originally match, making it easy to remove the barrel cover from the barrel body port or install the barrel cover on the barrel body port.

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0025] See Figures 1 to 3 As shown, this embodiment discloses a bearing packaging barrel cover removal and cover installation mechanism, including a frame 10, a barrel cover clamping assembly 20 and a barrel body clamping assembly 30 arranged on the frame 10, the barrel cover clamping assembly 20 is driven by an X-axis linear module 40, and moves back and forth in the X-axis direction, the barrel body clamping assembly 30 is driven by a Y-axis linear module 50, and moves back and forth in the Y-axis direction, a lifting assembly 60 is arranged between the barrel cover clamping assembly 20 and the barrel body clamping assembly 30, and the lifting assembly 60 includes a lifting rod 61 and a lifting cylinder 62, and the lifting cylinder 62 drives the lifting rod 61 to rise and fall, and the lifting rod 61 can act on the circumferential deformation of the barrel body clamped by the barrel body clamping assembly 30.
[0026] The bottom of the ejector rod 61 in this embodiment is in an arc shape to prevent the ejector rod 61 from damaging the barrel. The width of the lower end of the ejector rod 61 is smaller than the width of the upper end.
[0027] The ejector rod 61 is located above the clamped barrel body, and the ejector cylinder 62 is fixed above the clamped barrel body. The telescopic axis of the ejector cylinder 62 faces downward and is detachably connected to the connecting plate 63. The ejector rod 61 is detachably set on the connecting plate 63.
[0028] The barrel body clamping assembly 30 includes a barrel body base 31 and two barrel body clamping parts 32. The barrel body base 31 is driven by the Y-axis linear module 50. The end faces of the barrel body base 31 and the barrel body clamping parts 32 facing each other are provided with a first arc groove 34 that matches the barrel body. Each barrel body clamping part 32 is driven to rise and fall by a barrel body cylinder 33.
[0029] The barrel clamp 32 is offset from the barrel base 31 at least on the end thereof that faces the ejector rod 61. The barrel clamp 32 on the end facing the ejector rod 61 covers a portion of the barrel base 31, and a clearance space is formed on the side of the barrel clamp 32 facing the ejector rod 61. With the ejector rod 61 close to the clearance space, when the ejector rod 61 forces the barrel body to deform, the other portion of the barrel body is supported and fixed by the barrel base 31, facilitating partial circumferential deformation of the barrel body.
[0030] This embodiment also includes a barrel end clamping assembly 70, which includes a barrel body clamping cylinder 71, two rotating blocks, and two clamping plates 72. The barrel body clamping cylinder 71 is fixed to one side of the barrel body base 31 and drives the two rotating blocks to rotate toward or in opposite directions. The two clamping plates 72 are respectively fixed to the rotating blocks, and the two clamping plates 72 are each provided with a second arc-shaped groove 73 on the facing side. When the ejector rod 61 forces the barrel body to deform, the barrel body end clamping assembly 70 further fixes and supports the barrel body, further facilitating the partial deformation of the barrel body.
[0031] The barrel cover clamping assembly 20 includes a barrel cover clamping cylinder 21, three clamping moving blocks, three barrel cover clamping jaws 22 and a stepper motor 23. The barrel cover clamping cylinder 21 is arranged horizontally, and multiple barrel cover clamping jaws 22 moving blocks are arranged in a circle. The barrel cover clamping cylinder 21 drives multiple barrel cover clamping jaws 22 moving blocks to move back and forth toward and away from the center of the circle, and the stepper motor 23 drives the barrel cover clamping cylinder 21 to rotate.
[0032] The working principle of the cover pulling mechanism in this embodiment is as follows:
[0033] When the cut barrel body and barrel cover are loaded into the barrel body clamping assembly 30, the barrel body is clamped by the barrel body base 31 and the two barrel body clamping parts 32. At this time, the barrel cover is set at the barrel body port. The Y-axis linear module 50 drives the barrel body clamping assembly 30 to move in the Y-axis direction until it corresponds to the barrel cover clamping assembly 20. The barrel body clamping cylinder 71 of the barrel end clamping assembly 70 drives the two clamping plates 72 to rotate toward each other, clamping the barrel body port. The barrel cover clamping assembly 20 is moved by the X-axis. The linear module 40 is driven to move toward the barrel body to be clamped until the three barrel cover claws 22 of the barrel cover clamping assembly 20 clamp the barrel cover on the barrel body. At the same time, the ejection cylinder 62 drives the ejection rod 61 to descend. The ejection rod 61 deforms the upper surface of the barrel body to be clamped, and it is no longer circular, forming a notch. The X-axis linear module 40 drives the barrel cover clamping assembly 20 to retreat, and at the same time, the stepper motor 23 drives its barrel cover to rotate, and the barrel cover is easily pulled out from the port of the barrel body.
[0034] The working principle of the cover installation mechanism in this embodiment is:
[0035] When the barrel body is filled with a predetermined number of bearings, the two barrel body clamping parts 32 of the barrel body clamping assembly 30 are in a state of pressing against the barrel body base 31, and the Y-axis linear module 50 drives the barrel body clamping assembly 30 to move in the Y-axis direction until it corresponds to the barrel cover clamping assembly 20. The barrel body clamping claw cylinder 71 of the barrel end clamping assembly 70 drives the two clamping claw plates 72 to rotate toward each other to clamp the end part of the barrel body. The three barrel cover clamping claws 22 of the barrel cover clamping assembly 20 pre-clamp the barrel cover. At the same time, the top material cylinder 62 drives The ejector rod 61 descends, and the upper surface of the barrel body to be clamped by the ejector rod 61 is deformed and no longer circular, forming a notch. The barrel cover clamping assembly 20 is driven by the X-axis linear module 40 and moves toward the clamped barrel body. At this time, the barrel cover can be smoothly installed at the barrel body port. After installation, the ejector rod 61 resets and moves upward, and the three barrel cover claws 22 of the barrel cover clamping assembly 20 release the barrel cover. The X-axis linear module 40 drives the barrel cover clamping assembly 20 to retreat and reset, and the Y-axis linear module 50 moves the barrel body with the barrel cover to the next workstation.
