The invention is described in further detail below with reference to the following figures and detailed description:
example 1
As shown in fig. 1, this embodiment 1 describes a wire-withdrawing protection mechanism, which includes a housing 1, and a triggering mechanism, a wire-clamping limiting mechanism, and a wire-clamping mechanism located in the housing 1.
Wherein, trigger mechanism, card silk stop gear and card silk mechanism set gradually from front to back in shell 1.
The front-rear direction here is defined along the wire feed direction.
A wire guide hole penetrating through the shell 1 along the front-back direction is formed in the shell 1, so that a welding wire can conveniently penetrate through the wire guide hole.
The linkage process of the trigger mechanism, the wire clamping limiting mechanism and the wire clamping mechanism is as follows:
in the wire feeding state, the wire clamping mechanism does not act under the action of the wire clamping limiting mechanism, and the wire is fed normally;
when the wire withdrawing operation is carried out, the wire clamping limiting mechanism is opened, and when the welding wire passes through the trigger mechanism, the wire clamping limiting mechanism can be triggered to act, so that the wire clamping mechanism is driven to act. The action of the wire clamping mechanism is as follows:
after the welding wire leaves the trigger mechanism, the welding wire to be withdrawn is clamped, and wire breakage is prevented.
The following specifically describes the composition of the above-mentioned trigger mechanism, wire clamping limit mechanism and wire clamping mechanism.
As shown in fig. 2, the trigger mechanism includes a trigger block 2, a first compression spring 3, and a first cavity 4 arranged in the up-down direction.
the upper end of a compression spring 3 is arranged at the top of the cavity 4, and the lower end of the compression spring is connected with the trigger block 2.
As for the installation manner of the first compression spring 3, the present embodiment is not limited.
The first compression spring 3 can drive the trigger block 2 to move downwards along the first cavity 4. Of course, the trigger block 2 can also be pulled up along the first cavity 4 manually, as will be described in detail below.
Preferably, the trigger block 2 in this embodiment may be, for example, a square block.
The trigger block 2 is provided with a wire hole 5 which penetrates through the trigger block along the front-back direction, so that a welding wire 6 can conveniently penetrate through the wire hole.
In addition, a first shaft 16 is arranged on the side of the trigger block 2, so that the installation of a trigger rod is convenient.
In the first embodiment, when the first cavity 4 is designed, it is required to ensure that the trigger block 2 and the first shaft 16 can move along the first cavity 4.
As shown in fig. 3, the wire clamping mechanism includes a wire clamping block 7, a second compression spring 8, and a second cavity 9 arranged in the up-down direction.
The clamping wire block 7 and the second compression spring 8 are both positioned in the second cavity 9. Wherein:
the lower end of a second compression spring 8 is arranged at the bottom of the second cavity 9, and the upper end of the second compression spring is connected with the wire clamping block 7.
The installation manner of the second compression spring 8 is not limited in this embodiment.
The second compression spring 8 can drive the clamping screw block 7 to move upwards along the second cavity 9. Of course, the clamping wire block 7 can be pushed downwards along the cavity II 9 in a manual mode, and the method is described in detail below.
The top of the wire clamping block 7 is provided with a wire clamping groove 10, and the wire clamping groove 10 and the wire hole 5 are both positioned on a wire feeding line of the welding wire.
More specifically, the welding wire may pass through the wire clamping groove 10, for example, directly above the wire clamping groove.
When the wire clamping block 7 moves upwards, the wire clamping groove 10 moves upwards along with the wire clamping block 7 and clamps the welding wire to be withdrawn.
As shown in fig. 4 and 5, the clip block 7 has the following structure:
the wire clamping block 7 comprises a wire clamping plate 11 and a moving block 12, wherein the wire clamping plate 11 is connected with the moving block 12.
The connection method may be, for example, bolt connection, or may be welding connection.
The wire clamping plate 11 is of a rectangular plate-shaped structure, and the wire clamping groove 10 is arranged at the top of the wire clamping plate 11.
In addition, a limiting column 29 is further provided at the side of the wire clamping plate 11, and the limiting column 29 is cylindrical, which will be described in detail below.
The moving block 12 is a square block, and the upper end of the second compression spring 8 is connected to the moving block 12.
In the design of the second cavity 9 in this embodiment, it is required to ensure that the wire clamping block 7 and the limiting column 29 can move along the second cavity 9.
The wire clamping groove 10 in this embodiment may have a V-shaped structure, and the height position of the wire clamping groove 10 is designed to be just below the welding wire during wire feeding, and the V-shaped structure just clamps the welding wire when the wire clamping block 7 moves upwards.
Preferably, the wire clamping groove 10 in this embodiment is designed to be an upper and lower two-section structure, as shown in fig. 5, wherein the upper section of the wire clamping groove 10 is rectangular, the lower section thereof is V-shaped, and the width of the upper section of the wire clamping groove is the same as the diameter of the wire hole 5.
The above design can ensure that the welding wire is located in the upper section area of the wire clamping groove 10 during normal wire feeding, and when the welding wire needs to be clamped, the wire clamping groove 10 moves upwards along with the wire clamping block 7 and clamps the welding wire in the lower section area of the wire clamping groove 10.
The wire clamping effect of the wire clamping groove 10 with the two-section structure is obviously superior to that of the wire clamping groove 10 with the V-shaped structure.
As shown in figure 1, the wire clamping limiting mechanism is positioned between the trigger mechanism and the wire clamping mechanism.
The wire clamping limiting mechanism comprises a trigger rod 13, a gear 14, a pressure rod 15 and the limiting column 29. Wherein:
one end and the middle of the trigger lever 13 are provided with a shaft hole (not shown), respectively.
A first shaft 16 is provided on a side of the trigger block 2, and one end of the trigger lever 13 is attached to the first shaft 16.
The middle part of the trigger rod 13 is arranged on a second shaft 17 which is fixedly arranged.
Specifically, the second shaft 17 is mounted on the housing 1, and the design enables the trigger bar 13 to rotate around the second shaft 17 when the trigger block 2 moves up and down along the first cavity 4, so that the other end of the trigger bar 13 can move up and down.
The gear 14 is located below the other end of the trigger rod 13 and is mounted on a fixedly arranged third shaft 18. Gear 14 may rotate about third shaft 18. Specifically, the third shaft 18 is mounted on the housing 1.
When the trigger block 2 moves upwards to a certain position, one end of the trigger rod 13 is driven to rise, and the other end of the trigger rod 13 moves downwards until the trigger rod moves to abut against between two upper teeth of the gear 14.
At this time, the gear 14 cannot rotate due to abutment of the trigger lever 13.
As for the portion of the trigger bar 13 between the second shaft 17 and the gear 14, it may be designed in an arc shape curved upward.
The pressing rod 15 is located above the trigger rod 13 and is used for achieving position locking of the trigger rod 13.
One end of the pressure lever 15 is mounted on a fixed fourth shaft 19, and the other end is a free end.
The strut 15 is rotatable about the fourth shaft 19, and in particular, the fourth shaft 19 is mounted to the housing 1.
Preferably, the pressing rod 15 is, for example, an arc-shaped rod, and the bending direction is downward.
In the wire feeding state, the pressing rod 15 is manually rotated and pressed down on the trigger rod 13, and the gear 14 cannot move freely.
The limiting column 29 is clamped between two teeth on the side of the gear 14 when the limiting column follows the clamping screw block 7 to move downwards to a certain position.
At the moment, the wire clamping limiting mechanism is in a limiting state, and the wire withdrawing protection mechanism does not work.
Meanwhile, the first compression spring 3 and the second compression spring 8 are both in a compressed (energy-storing) state.
The action process of the wire clamping limiting mechanism in the embodiment is as follows:
the pressing rod 15 is manually moved upwards, and the trigger rod 13 is not limited by the pressing rod 15 any more;
in the wire withdrawing process, after the welding wire is withdrawn from the wire hole 5, the first compression spring 3 releases stored energy and drives the trigger block 2 and the trigger rod 13 to move downwards, and the other end of the trigger rod 13 is separated from the gear 14;
at this time, the gear 14 can move freely, so that the limit column 29 is not limited any more;
the second compression spring 8 releases stored energy and drives the wire clamping block 7 to move upwards, and the welding wire 6 is clamped in the wire clamping groove 10.
This embodiment has realized the accurate control of the silk process of moving back, prevents to collapse the silk, avoids the waste of potential safety hazard and material, man-hour.
In addition, in order to reset the wire clamping block 7, a handle 20 may be provided on a side portion of the moving block 12, and as shown in fig. 5, one handle 20 may be provided on each of two opposite side portions of the moving block 12.
Preferably, the handle 20 may be, for example, a long rod.
The handle 20 is manually depressed downward to remove the remaining wire and prevent wire breakage. The handle 20 is then depressed further so that the post 29 snaps back between the two teeth on the side of the gear 14. At the same time as this is done,
the pressing rod 15 is rotated so that the other end of the trigger lever 13 abuts between two teeth on the upper portion of the gear 14, and the wire is normally fed.
The shell 1 is also provided with a strip-shaped hole 21 for the handle to move up and down, and the handle 20 extends out of the shell 1 through the strip-shaped hole 21.
Of course, the wire-withdrawing protection mechanism in this embodiment 1 may be applied to wire-withdrawing protection of rigid wires with wire-withdrawing requirements and other disc-shaped structures besides being applied to wire-withdrawing of welding wires, and is not described herein again.
Example 2
This embodiment 2 describes a wire feeder that includes a wire spool 22 and a wire feeder 23, as shown in fig. 6.
In addition, the wire feeder further comprises a wire withdrawing protection mechanism 24 positioned between the wire reel 22 and the wire feeding mechanism 23, so as to realize accurate control of the wire withdrawing process of the welding wire and avoid wire breakage caused by excessive wire withdrawing.
Specifically, the wire-withdrawal guard 24 is located on the wire path between the wire reel 22 and the wire feeder 23, that is:
the welding wire of the wire reel 22 passes through the upper part of the wire clamping groove 10 and the wire hole 5 from back to front to reach the wire feeding mechanism 23.
The wire withdrawing process of the wire feeder in this embodiment 2 specifically includes:
firstly, a pressurizing mechanism of the wire feeding mechanism 23 is opened, then a pressure rod 15 of the wire clamping limiting mechanism is rotated upwards, and after the welding wire is completely withdrawn from the wire hole 5, the wire clamping mechanism can clamp the welding wire in time, so that the precise control of the wire withdrawing of the welding wire is realized.
In addition, the wire withdrawing protection mechanism also has the advantages of simple and convenient actual operation, no influence on normal wire feeding and the like.
Example 3
The present embodiment 3 also describes a wire feeder, and the wire feeder in the present embodiment 3 can refer to the above embodiment 2 except that the following technical features are different from those of the above embodiment 2.
This embodiment 3 changes the manual mode of moving back among the prior art into electronic mode of moving back, promptly:
the wire withdrawing motor is additionally arranged on the wire reel 22 to realize the automatic wire withdrawing process of the welding wire, and meanwhile, the automatic wire withdrawing process of the wire feeder can be realized by matching with the wire withdrawing protection mechanism in the embodiment 1, so that the wire withdrawing efficiency and the safety are obviously improved.
Specifically, the wire feeder further comprises a controller and other components, and the controller can adopt a programmable logic control device such as a single chip microcomputer.
As shown in fig. 7, the wire feeder 23 includes a motor 25, a wire feeding wheel 26, and a pressing mechanism 27. Wherein:
the number of the wire feeding wheels 26 is two, and the output shaft of the first motor 25 is provided with a driving wheel which is respectively meshed with the two wire feeding wheels 26.
The first motor 25 is used for driving the wire feeding wheel 26 to rotate.
In addition, a pressurizing mechanism 27 is respectively arranged above each wire feeding wheel 26, and the welding wire on the corresponding wire feeding wheel 26 is pressed through the pressurizing mechanism 27 so as to ensure that the welding wire can be better conveyed forwards under the driving of the first motor 25.
It should be noted that the prior art motor 25 only uses forward rotation to achieve the wire feed. In the present embodiment, the first motor 25 is designed to be capable of rotating in both the forward direction and the reverse direction.
In addition, a second motor 28 is connected to wire reel 22 for driving wire reel 22 to rotate. Specifically, the second motor 28 is connected to a disc shaft of the wire reel 22, and the wire reel 22 is integrally rotated by driving the disc shaft to rotate.
Since the second motor 28 in this embodiment may also rotate forward or backward, the second motor 28 may also drive the wire reel 22 to rotate forward to cooperate with the first motor 25 to feed the welding wire, and of course, may rotate backward to realize wire withdrawal.
It should be noted that it is not necessary for the second motor 28 to rotate forward to achieve the wire feeding, because the wire feeding can be achieved by the single action of the first motor 25, and of course, the second motor 28 can assist in achieving the wire feeding.
The second motor 28 is arranged in the embodiment, and mainly has the function of realizing the automatic wire withdrawing function of the welding wire, so that the defects existing in the prior art when the excessive welding wire is cut off due to manual wire withdrawing or over-long dry extension are overcome.
The controller is connected with the first motor 25 and the second motor 28 through control lines respectively.
When the welding wire is required to be conveyed, the controller can control the first motor 25 to rotate forwards so as to realize the welding wire conveying; when the wire withdrawing is needed, the controller controls the first motor 25 and the second motor 28 to rotate reversely at the same time, so that the wire withdrawing operation is realized.
In the automatic wire withdrawing process, the wire withdrawing protection mechanism is arranged, so that the precise control of the wire withdrawing process can be realized.
In addition, in this embodiment, a jog wire withdrawing switch and a jog wire feeding switch may be further added to the welding gun, wherein the jog wire withdrawing switch and the jog wire feeding switch are respectively connected to the controller, and when the jog wire withdrawing switch is clicked, an automatic wire withdrawing process of the wire feeder may be implemented.
The embodiment has the advantages of convenient operation, automatic wire withdrawing, accurate control of the wire withdrawing degree and the like, and avoids the occurrence of wire breakage.
It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
