Door closer piston clamping and feeding mechanism

Abstract

The utility model provides a door closer piston clamping and feeding mechanism which comprises a U-shaped clamping jaw capable of moving up and down. A discharging groove is formed in the upper side of the clamping jaw and is provided with an upward opening, and a first opening corresponding to the clamping jaw is formed in the bottom of the discharging groove. A U-shaped rotating piece is arranged in the first opening, the two sides of the rotating piece are hinged to the side wall of the first opening, and the clamping jaw can penetrate through the first opening. A cylindrical piston conveyed in the axial direction firstly enters a clamping jaw, then the clamping jaw moves upwards and penetrates through a first opening to jack up a rotating piece till the rotating piece rotates to be in a vertical state, at the moment, the clamping jaw crosses over the rotating piece, moves to the upper side of a discharging groove, then moves downwards, penetrates through the middle of the rotating piece and then penetrates through the first opening, and then the rotating piece rotates to be in a vertical state. In the process, the piston is stopped by the rotating piece and stays in the discharging groove, and then the piston moves along the discharging groove, so that the piston conveyed in the axial direction of the piston is converted into the piston conveyed in the radial direction of the piston, and the conveying direction of the piston is changed.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] For reference Figure 1-7 The utility model is described as follows:

[0034] Embodiment 1: A door closer piston clamping and feeding mechanism,

[0035] It includes a U-shaped clamping claw 1 and a U-shaped feed seat 6. The clamping claw 1 is arranged on the inner side of the feed seat 6 and can move up and down. The feed seat 6 is provided with a feed groove 7, which runs through the upper side and a side of the feed seat 6. The feed seat 6 is provided with a connecting groove 8 that runs through the upper and lower sides thereof. The connecting groove 8 is arranged in the middle position of the feed seat 6. The clamping claw 1 is connected to the connecting groove 8. The clamping claw 1 has a clamping groove 10. The lower sides of the connecting groove 8 and the clamping groove 10 are both arc-shaped and coaxially arranged. The cylindrical piston enters the feed groove 7 and the clamping groove 10 from one side of the feed seat 6, and the clamping claw 1 moves upward again, carrying the piston upward.

[0036] A discharge trough 2 is provided on the upper side of the clamping claw 1. The discharge trough 2 is long and strip-shaped. The discharge trough 2 is opened upward. The cross-section of the discharge trough 2 is a U-shaped structure. The discharge trough 2 is inclined. The end of the discharge trough 2 corresponding to the clamping claw 1 is higher than the other end. An opening 3 corresponding to the clamping claw 1 is provided at the bottom of the discharge trough 2. When the clamping claw 1 moves upward, it can carry the piston through the opening 3. A U-shaped rotating member 4 is provided in the opening 3. The two sides of the middle part of the rotating member 4 are hinged to the side walls of the opening 3, so that the rotating member 4 can rotate. When the clamping claw 1 passes through the opening 3, the upper end of the clamping claw 1 also lifts the rotating member 4, and the rotating member 4 rotates accordingly. When the rotating member 4 rotates to a vertical state, the clamping claw 1 and the piston can pass over the rotating member 4, and the rotating member 4 then rotates downward and returns to its original position under the action of its own gravity, and the clamping claw 1 moves downward again. During the downward movement of the clamping claw 1, the clamping claw 1 passes through the middle of the rotating member 4, and the piston is blocked by the two sides of the rotating member 4 and stays in the discharge trough 2, and is rolled and transported along the discharge trough 2.

[0037] The length of the piston is greater than the distance between the two side walls of the rotating member 4 .

[0038] The projection of the feeding direction of the feeding trough 7 on the horizontal plane is arranged perpendicular to the projection of the discharging direction of the discharging trough 2 on the horizontal plane.

[0039] A support portion 5 is provided at the bottom of the discharge chute 2 to support the rotating member 4, and the support portion 5 can prevent the rotating member 4 from rotating toward the lower side of the opening 3. The rotating member 4 rotates upward when it is lifted up, and when the rotating member 4 rotates to a vertical state, one side of the rotating member 4 is restricted by the clamping claw 1, and the other side of the rotating member 4 is restricted by the piston resting on the discharge chute 2, so that when the clamping claw 1 passes over the rotating member 4, the rotating member 4 can rotate downward.

[0040] The rotating member 4 is a plate-like structure, and the thickness of the rotating member 4 from the hinge side to the other side is gradually thickened. With this technical solution, the weight of the rotating member 4 away from its hinge end will be greater, which helps the rotating member 4 in a vertical state to rotate downward. Of course, a limiting structure can also be set on the side wall of the discharge chute 2 to prevent the rotating member 4 from rotating. When the rotating member 4 rotates upward to a vertical state, it collides with the limiting structure, preventing the rotating member 4 from rotating, so that the rotating member 4 can only rotate.

[0041] It also includes a cylinder 11 for driving the clamping claw 1 to move up and down. The clamping claw 1 is driven to move up and down by the cylinder 11.

[0042] It also includes a bearing seat, which includes two bearing plates 16 spaced apart from each other, and a frame 17 connecting the two bearing plates 16. A cylinder 11 is arranged below the bearing seat, and the cylinder 11 is used to drive the bearing seat to move up and down. A vertically arranged connecting rod 12 is connected to the bearing seat, and the connecting rod 12 is rotatably connected to the two bearing plates 16 through a bearing. The upper end of the connecting rod 12 is fixedly connected to the clamping claw 1. The bearing seat moves up and down to drive the connecting rod 12 to move up and down, and drives the clamping claw 1 to move up and down. In this way, the up and down movement control of the piston is realized.

[0043] A gear 13 is fixedly provided on the connecting rod 12, and the gear 13 is coaxial with the connecting rod 12, and also includes a rack 14 meshing with the gear 13. A cylinder 2 15 for driving the rack 14 to move is provided on the frame 17. The cylinder 2 15 drives the rack 14 to move back and forth, and the rack 14 drives the gear 13 and the connecting rod 12 to rotate forward and backward, thereby driving the clamping claw 1 to rotate. In this way, the clamping claw 1 can be rotated 180 degrees, and the direction of the piston can be rotated to cooperate with the next process.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
