Furthermore, in the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, one of the purposes of the present invention is to provide a vertical feeding metal sleeve welding device, which comprises a bottom plate 100 and a top plate 101 which are oppositely arranged in a longitudinal manner, wherein the bottom plate 100 and the top plate 101 are connected through a telescopic rod 102, the telescopic rod 102 is composed of two mutually sliding rod bodies, one rod body is fixedly connected with the bottom plate 100, the other rod body is fixedly connected with the top plate 101, a cylinder 103 is arranged at the rod body connected with the bottom plate 100, and the movable end at the top of the cylinder 103 is connected with the top plate 101. Thereby raising and lowering the top plate 101 by the expansion and contraction of the cylinder 103.
In fig. 2, a connecting tube 110 having a hollow structure is provided between a bottom plate 100 and a top plate 101, and when two sleeves 200 are fitted around the outer ring of the connecting tube 110, the connecting tube 110 restricts the two sleeves 200 to a coaxial state. In fig. 3, a turntable 104 for carrying a workpiece 201 is rotatably provided on a surface of the bottom plate 100 and a surface of the top plate 101, and a through hole 105 is formed in the turntable 104. Then, the connection cylinder 110 is connected to the base plate 100 through the through hole 105.
In fig. 4, a through groove 111 is formed on the side wall of the connecting cylinder 110, and a sleeve carrier 130 is elastically arranged in the longitudinal direction; the end of the sleeve carrier 130 shuttles back and forth at the through groove 111 in a telescopic manner to support the sleeve 200 when the end of the sleeve carrier 130 is extended out of the outer ring of the connection cylinder 110, and to disengage the sleeve 200 when the end of the sleeve carrier 130 is retracted inside the connection cylinder 110. And, the elasticity of the support sleeve carrier 130 is greater than the weight of a single sleeve 200 and less than the weight of two sleeves 200.
Thus, when the two sleeves 200 are sleeved on the outer ring of the connecting cylinder 110, the two sleeves 200 press the sleeve carrier 130 to descend, and the ends of the sleeve carrier 130 are contracted in the descending process and then extend out so as to be separated from the sleeves 200 at the bottom, so that the sleeves 200 at the top are pushed upwards by elasticity, and the sleeves 200 at the top are contacted with the workpiece 201 at the top.
Then, a robot 140 is provided at one side of the connection cylinder 110, and a welding gun 141 is connected to an end effector of the robot 140. The end effector is an actuator of a manipulator, that is, a hand of the robot 140, is a part mounted on an arm of the robot 140 to directly grasp a part or perform a work, and has a function of holding, transporting, and placing the part to a certain position. In this way, the robot 140 can control the welding gun 141 to weld the sleeve 200 and the workpiece 201.
That is, the two sleeves 200 are limited by the connecting cylinder 110 disposed longitudinally, so that the two sleeves 200 are in a longitudinal state during welding, thereby reducing occupation of floor space.
Moreover, the telescopic characteristic of the end of the sleeve carrier 130 can be contracted and then extended in the descending process, so that the sleeve 200 at the bottom is lowered, and the sleeve 200 at the top is lifted, so that the sleeve 200 at the top is contacted with the workpiece 201 at the top, and the support of the sleeve 200 at the top is achieved.
In embodiment 1, as shown in fig. 3, four clamping blocks 108 are slidably disposed on the outer ring of the turntable 104, and the four clamping blocks 108 can all move toward the center of the turntable 104, so that the workpiece 201 is clamped and fixed during the movement. And, the top of carousel 104 rotates and is provided with swivel 106, and the inner circle of swivel 106 inwards protrudes and forms bulge loop 107. Thus, when the swivel 106 rotates, the swivel 106 drives the convex ring 107 to rotate, so that the convex part of the convex ring 107 pushes the clamping block 108, and the clamping block 108 moves towards the center of the turntable 104, thereby realizing the effect of clamping the workpiece 201.
As shown in fig. 4, the sleeve carrier 130 includes a round bar 131 positioned inside the connection cylinder 110, a slider 132 slidably disposed at an outer circumference of the round bar 131, and a bearing block 134 slidably disposed at an end of the slider 132, one end of the bearing block 134 having an inclined surface disposed obliquely so that when the bearing block 134 reaches the bottom of the through groove 111, the bearing block 134 is moved toward the inside of the base plate 100 by pressing the inclined surface of the end of the bearing block 134 against the bottom of the through groove 111. The round rod 131 is fixedly disposed at the top of the bottom plate 100, a supporting spring 136 elastically connecting the bottom of the sliding block 132 and the top of the bottom plate 100 is disposed between the bottom of the sliding block 132 and the top of the bottom plate 100, a sliding groove 133 is formed at the end of the sliding block 132, a bearing block 134 is slidably disposed in the sliding groove 133, and a return spring 135 elastically connecting the one end of the bearing block 134 and the inner end of the sliding groove 133 is disposed between them. The elasticity of the support spring 136 is greater than the weight of a single sleeve 200 and less than the weight of two sleeves 200.
In addition, it is considered that when the two sleeves 200 are stacked together, a gap is hardly generated at a portion where the two sleeves are in contact, and it is thus difficult to make the carrier block 134 protrude between the two sleeves 200. For this, as shown in fig. 5 and 6, the outer ring of the connection cylinder 110 is slidably provided with a spacer ring 120 that spaces the two sleeves 200 into a spacer space 121. Specifically, the bottom of the spacer 120 protrudes to form a bump. The spacer ring 120 is then positioned between the two sleeves 200, with the spacers 121 being formed between the two sleeves 200 under the support of the lugs.

as shown in fig. 5 and 6, first, the control cylinder 103 pushes the top plate 101, at this time, the top of the connecting cylinder 110 is separated from the top plate 101, then one workpiece 201 is placed above the top turntable 104 of the bottom plate 100 along the outer circumference of the connecting cylinder 110, then the other workpiece 201 is placed below the bottom turntable 104 of the top plate 101, and then the two workpieces 201 are fixed by the clamping block 108. Then, the spacer ring 120 is placed between the two sleeves 200, and the two sleeves 200 and the spacer ring 120 are placed along the outer circumference of the connection cylinder 110. The state at this time is as shown in fig. 5. The bumps at the bottom of the spacer rings 120 space the two spacer rings 120 apart into a spacer cavity 121.
Then, the weight of the two sleeves 200 overcomes the elasticity of the supporting springs 136, so that the bearing block 134 is pressed to move downwards, when the bearing block 134 moves downwards to the bottom of the through groove 111, the inclined surface at the end of the bearing block 134 is pressed by the bottom of the through groove 111, so that the reset spring 135 is forced to compress and drive the bearing block 134 to move inwards of the bottom plate 100, at the moment, the bearing block 134 is separated from the bottom sleeve 200, and the bottom sleeve 200 falls down to the top of the bottom workpiece 201 in a proper manner; after the carrier block 134 is separated from the bottom sleeve 200, the elasticity of the supporting spring 136 pushes the carrier block 134 to move upward for restoration, and when the carrier block 134 moves up to the space 121, the elasticity of the restoring spring 135 pushes the carrier block 134 for restoration, so that the carrier block 134 protrudes below the top sleeve 200, and then the top sleeve 200 is pushed upward by the elasticity of the supporting spring 136 to move the sleeve 200 upward for contact with the top workpiece 201.
At this time, both the sleeves 200 are in contact with the workpiece 201, and then the welding gun 141 may weld the portion of the sleeve 200 in contact with the workpiece 201.
In embodiment 2, as shown in fig. 4, the outer ring of the round bar 131 is provided with a screw groove, so that the slider 132 is screw-coupled with the round bar 131. And, the bottom of the slider 132 is rotatably provided with a ring plate 137 for separating the support spring 136 from the slider 132, thereby preventing the support spring 136 from affecting the rotation of the slider 132. In addition, a driving member 150 for driving the turntable 104 to rotate is provided between the connection cylinder 110 and the top plate 101, and when the sleeve 200 moves longitudinally on the outer circumference of the connection cylinder 110, the driving member 150 drives the turntable 104 at the top plate 101 to rotate by using the moving force of the sleeve 200.
