Description

Technical Field

[0001] The utility model relates to the field of winding, in particular to a wire passing, hanging and de-wire mechanism for multiple wires in an inner stator. Background Art

[0002] The winding machine is used to wind the enameled wire on the stator core. During the winding process of the existing winding machine, the lower wire passing mechanism in the winding machine is easy to be unhooked when encountering multiple wires, i.e., more than or equal to 4 wires, and thick wires, i.e., wire diameters greater than or equal to 0.8mm. When the stator core is unloaded after winding, it is very difficult for the lower wire passing enameled wire to hook, which affects the production efficiency and product quality. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a wire-passing, hanging and unwinding mechanism for multiple wires in an inner stator, which can prevent the problem of unhooking during the winding process and facilitate the unwinding of the wires after winding.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A wire passing, hanging and de-wire mechanism for inner stator multi-strand wires, characterized by comprising a fixing seat, a wire passing column, a de-wire pipe, a wire blocking hook and a reset spring;

[0006] The wire-passing post is fixed to the bottom of the fixing seat, the front end of the wire-passing post is for the enameled wire to pass around, and has a mounting groove extending forward and backward;

[0007] The rear end of the wire blocking hook is hinged in the installation slot, the front end has a hook body and can rotate up and down, and a pressing spring is arranged between the wire blocking hook and the wire passing column to press the hook body down to the outside of the installation slot;

[0008] The wire stripping tube is sleeved on the wire passing post and can move axially along the wire passing post. When the wire stripping tube moves forward, it can push the hook body into the installation groove and simultaneously push the enameled wire on the front end of the wire passing post away from the wire passing post. A return spring is provided between the wire passing post and the wire stripping tube to push the wire stripping tube backward.

[0009] Preferably, there are guide plates on both sides of the wire passing column, and the wire passing column is fixed to the fixed seat through the guide plates. There are guide grooves on both sides of the wire stripping tube, and the guide grooves penetrate the rear end wall of the wire stripping tube for the wire passing column and the mounting plate to be inserted into the wire stripping tube from the rear end of the wire stripping tube.

[0010] Preferably, an end cover is fixed to the rear end of the wire-stripping tube, the rear end of the reset spring abuts against the end cover, and the front end abuts against the rear end position of the wire-passing column.

[0011] Preferably, a connection block extending downward is provided at the rear end of the de-wire tube.

[0012] Preferably, the wire retaining hook is provided with a guide portion which protrudes downward and against which the front end wall of the wire stripping tube abuts.

[0013] The utility model has the following advantages: under the action of the reset spring, the wire stripping tube moves backward, and the hook body of the wire blocking hook swings down to the outside of the installation groove under the action of the downward pressure spring, and multiple strands of thick enameled wires pass through the front end of the wire-passing column when passing the wires downward. Since the hook body extends downward to protect the enameled wires, the enameled wires are completely prevented from stripping when passing the wires downward, and enter the next groove for winding; after the winding is completed, the wire stripping tube is pushed forward, which not only moves the hook body upward and turns into the installation groove, but also after the wire stripping tube moves forward, the enameled wire passing the wire downward is pushed out of the front end of the wire-passing column, and the enameled wire passing the wire downward is separated from the entire mechanism, which is convenient for operators to load and unload materials.

[0015] Figure 2 It is a cross-sectional view of the inner stator multi-strand wire under-wire passing and hanging off-wire mechanism provided in this embodiment. DETAILED DESCRIPTION

[0016] Combination Figure 1 to Figure 2 The utility model is further described on the inner stator multi-strand wire under-wire passing and hanging off-wire mechanism.

[0017] A wire passing, hanging and de-wire mechanism for inner stator multi-strand wires, characterized by comprising a fixing seat 1, a wire passing column 2, a de-wire tube 3, a wire blocking hook 5 and a reset spring 6.

[0018] The fixing seat 1 is used for being installed on the tooling of the winding machine.

[0019] The wire-passing post 2 is fixed to the bottom of the fixing seat 1, and the front end 22 of the wire-passing post 2 is for the enameled wire 4 to pass around, and the front end 21 of the wire-passing post 2 has a mounting groove 21 extending forward and backward and penetrating the wire-passing post 2 up and down; the rear end of the wire-blocking hook 5 is hinged in the mounting groove 21 through a pin shaft, and the front end has a hook body 51 and can rotate up and down. In a natural state, the hook body 51 can swing down to the bottom of the mounting groove 21 due to its own weight to hook the enameled wire 4. In order to improve the stability of the hook, a downward pressing spring 8 is provided between the upper surface of the wire-blocking hook 5 and the wire-passing post 2 in this embodiment to press the hook body 51 down to the outside of the mounting groove 21.

[0020] The wire stripping tube 3 is sleeved on the wire passing post 2 and can move axially along the wire passing post 2. When the wire stripping tube 3 moves forward, it can push the hook body 51 into the installation groove 21, and at the same time, it can push the enameled wire 4 on the front end 22 of the wire passing post 2 away from the wire passing post 2. A return spring 6 is provided between the wire passing post 2 and the wire stripping tube 3 to push the wire stripping tube 3 backward.

[0021] Specifically, a top wall 23 is provided on the upper notch at the rear end of the mounting slot 21, the upper end of the downward pressure spring 8 is pressed against the positioning slot on the lower surface of the top wall 23, and the lower end is pressed against the positioning slot on the upper surface of the wire blocking hook 5, pressing the hook body 51 downward.

[0022] There are guide plates 21 on both sides of the wire-passing column 2, and guide grooves 31 on both sides of the wire-off tube 3. The guide grooves 31 penetrate the rear end wall of the wire-off tube 3, so that the wire-passing column 2 and the mounting plate can be inserted into the wire-off tube 3 from the rear end of the wire-off tube 3. The cooperation between the guide plates 21 and the guide grooves 31 can ensure that the wire-off tube 3 slides stably on the wire-passing column 2, and limit the backward movement distance of the wire-off tube 3 relative to the wire-passing column 2, so that the wire-off tube 3 cannot be separated from the rear end of the wire-passing column 2, and at the same time, the front end portion 22 of the wire-passing column 2 can be located outside the wire-off tube 3, so that the enameled wire 4 can bypass.

[0023] The wire-passing post 2 is fixed to the fixing seat 1 through the guide plate 21 , that is, a connecting hole is provided on the guide plate 21 , and after the connecting hole is docked with the connecting hole on the fixing seat 1 , the wire-passing post 2 can be fixed to the bottom position of the fixing seat 1 by screwing in a bolt.

[0024] An end cover 7 is fixed to the rear end of the de-wire tube 3, and the end cover 7 is fastened by bolts. The rear end of the return spring 6 abuts against the positioning groove on the end cover 7, and the front end abuts against the positioning groove at the rear end of the wire passing column 2, thereby providing a thrust for the de-wire tube 3 to move backward.

[0025] A connection block 32 extending downward is provided at the rear end of the wire-off tube 3 , and the connection block 32 can be connected to an external displacement driving component such as a cylinder to drive the wire-off tube 3 to move forward and backward relative to the wire-passing column 2 .

[0026] The wire blocking hook 5 is provided with a guide portion 52 which protrudes downward and for the front end wall of the wire stripping tube 3 to abut against. The guide portion 52 is located on the front side of the hinged position. The guide portion 52 is gradually inclined downward from the back to the front. Therefore, when the wire stripping tube 3 moves forward, it abuts against the guide portion 52, which can push the wire blocking hook 5 to gradually rotate upward around the hinged position, so that the hook body 51 is rotated into the installation groove 21.

[0027] When in use, under the action of the reset spring 6, the wire stripping tube 3 moves backward, and the hook body 51 of the wire blocking hook 5 swings down to the outside of the installation groove 21 under the action of the downward pressure spring 8. When the multi-strand thick enameled wire 4 passes through the front end 22 of the wire passing column 2, the hook body 51 extends downward to protect the enameled wire 4, so that the enameled wire 4 is completely prevented from being stripped when passing through the wire, and enters the next groove for winding; after the winding is completed, the wire stripping tube 3 is pushed forward, which not only moves the hook body 51 upward and turns into the installation groove 21, but also after the wire stripping tube 3 moves forward, the enameled wire 4 passing through the wire is pushed out of the front end 22 of the wire passing column 2, and the enameled wire 4 passing through the wire is separated from the entire mechanism, which is convenient for the operator to load and unload.
