Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and in particular relates to a positioning fixture for a framework of an automatic winding machine. Background Art

[0002] When the automatic winding machine implements coil winding, the coil skeleton is generally installed on the skeleton fixing device first, and then the skeleton fixing device is installed on the main shaft of the automatic winding machine. The main shaft is fixed and drives the skeleton to rotate together, so as to realize the winding. When the winding is completed, the skeleton with the wire wound needs to be removed from the skeleton fixing device, replaced with an empty skeleton, and then the wire is wound.

[0003] The existing automatic winding machine frame positioning fixture requires repeated tightening of the clamping device, which makes the winding machine frame loading and unloading process very troublesome. At the same time, during the high-speed rotation of the winding machine frame, the stability performance is poor and the positioning effect cannot be achieved. Utility Model Content

[0006] The beneficial effects of the utility model are as follows: the operator can quickly place the coil skeleton between the clamping head two and the clamping head one after pulling out the pull rod, and after loosening the pull rod, the clamping head two is pressed against the coil skeleton under the elastic support of the support spring, so that the installation and positioning of the coil skeleton can be completed quickly and firmly, and the coil skeleton can be quickly removed; by adjusting the position of the tube clamp on the guide rod, the device can quickly clamp coil skeletons of different lengths.

[0007] In order to make the clamping head 2 rotate stably under the drive of the coil frame;

[0008] As a further improvement of the above technical solution: a slot hole adapted to install the second sliding sleeve is opened on the machine body, and the pull rod is slidably inserted in the second sliding sleeve.

[0009] The beneficial effect of this improvement is that the second sleeve cooperates with the bearing seat to provide support for the pull rod, effectively reducing the shaking of the pull rod when it rotates, so that the coil skeleton can rotate stably under the clamping of the skeleton driving component and the skeleton driven component.

[0010] To save effort, pull the lever;

[0011] As a further improvement of the above technical solution: a handle is installed at one end of the pull rod away from the clamping head 2.

[0012] The beneficial effect of this improvement is that the operator can hold the handle and pull the pull rod with less effort, thereby conveniently taking and placing the coil skeleton.

[0013] In order to ensure the stability of the connection plate movement;

[0014] As a further improvement of the above technical solution: there are multiple guide rods, and the axes of the guide rods are parallel to the axes of the pull rods.

[0015] The beneficial effect of this improvement is that the multiple guide rods can support the stable movement of the connecting plate, thereby enabling the connecting plate to drive the pull rod and the clamping head to move stably.

[0016] In order to prevent the entire device from moving when the operator pulls the rod;

[0017] As a further improvement of the above technical solution: a bottom plate is provided at the bottom of the machine body, and a fixing groove is provided on the bottom plate.

[0018] The beneficial effect of this improvement is that the operator can insert the bolt into the fixing groove and connect the workbench, so that the device is firmly installed on the workbench, and the entire device is prevented from moving when the operator pulls the pull rod.

[0019] In order to make the coil frame rotate stably under the drive of the frame drive assembly;

[0020] As a further improvement of the above technical solution: a groove body adapted to fit and embed the anti-skid protrusion is opened on the conical surface of the clamping head one, and the slope of the outer surface of the anti-skid protrusion is the same as the slope of the clamping head one.

[0021] The beneficial effect of this improvement is that the anti-skid protrusions are elastically deformed after being squeezed by the coil frame, which effectively increases the friction between the frame drive assembly and the coil frame, so that the coil frame can rotate stably under the drive of the frame drive assembly.

[0022] In order to fully ensure the centering installation of the coil frame;

[0023] As a further improvement of the above technical solution: the axis of the clamping head 1 is colinear with the axis of the clamping head 2, and both the clamping head 1 and the clamping head 2 are conical block structures.

[0024] The beneficial effect of this improvement is that the clamping head 1 and the clamping head 2 can cooperate to squeeze the two ends of the coil skeleton, and under the support of the conical surface, the axes of the coil skeleton and the clamping head 1 and the clamping head 2 are kept in line.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1—5 shows: a skeleton positioning fixture of an automatic winding machine, comprising a machine body 1, a linear moving component 2 is installed on the machine body 1, a connecting frame 3 is installed on the slide seat of the linear moving component 2, a magnetic tensioner 4 and a wire nozzle 5 are installed on the connecting frame 3, a skeleton driving component 7 and a skeleton driven component 8 are installed on the left and right sides of the machine body 1, the skeleton driving component 7 comprises a clamping head 72, the clamping head 72 is installed on the output shaft of the driving motor 71, the driving motor 71 is installed on the machine body 1, the skeleton driven component 8 comprises a guide rod 81, both ends of the guide rod 81 are connected to the machine body 1, a sliding sleeve 82 is slidably installed on the guide rod 81 and the clamp A pipe clamp 84 is installed, the sliding sleeve 1 82 is installed on the connecting plate 83, a support spring 85 is installed on the guide rod 81 between the connecting plate 83 and the pipe clamp 84, a bearing seat 86 is installed on the connecting plate 83, a pull rod 88 is rotatably mounted in the bearing seat 86, and a clamping head 2 80 is installed on the end of the pull rod 88 facing the skeleton driving component 7. The operator can quickly put the coil skeleton between the clamping head 2 80 and the clamping head 1 72 after pulling the pull rod 88, and after loosening the pull rod 88, the clamping head 2 80 is pressed against the coil skeleton under the elastic support of the support spring 85, so that the installation and positioning of the coil skeleton are completed quickly and stably, and the coil skeleton can be quickly removed;By adjusting the position of the pipe clamp 84 on the guide rod 81, the device can quickly clamp coil skeletons of different lengths. A slot hole adapted to install the second sliding sleeve 87 is opened on the body 1. The pull rod 88 is slidably inserted in the second sliding sleeve 87. The second sliding sleeve 87 cooperates with the bearing seat 86 to provide support for the pull rod 88, effectively reducing the shaking of the pull rod 88 when rotating, so that the coil skeleton can rotate stably under the clamping of the skeleton driving component 7 and the skeleton driven component 8. The pull rod 88 is installed with a handle 89 at the end away from the clamping head 80, and the operator can hold the handle 89 and pull the pull rod 88 with ease, so as to conveniently take and place the coil skeleton. The number of the guide rods 81 is multiple, and the axis of the guide rod 81 is parallel to the axis of the pull rod 88. Multiple guide rods 81 can support the stable movement of the connecting plate 83, so that the connecting plate 83 drives the pull rod 88 and the clamping head 80 to move stably. The bottom of the body 1 is provided with a bottom plate 9. A fixing groove 6 is provided on the bottom plate 9. The operator can insert the bolt into the fixing groove 6 and connect the workbench to firmly install the device on the workbench to prevent the device from moving as a whole when the operator pulls the pull rod 88. A groove body adapted to fit the anti-skid protrusion 73 is provided on the conical surface of the clamping head 1 72. The slope of the outer surface of the anti-skid protrusion 73 is the same as that of the clamping head 1 72. The anti-skid protrusion 73 is elastically deformed after being squeezed by the coil skeleton, effectively increasing the friction between the skeleton driving component 7 and the coil skeleton, so that the coil skeleton can rotate stably under the drive of the skeleton driving component 7. The axis of the clamping head 1 72 is collinear with the axis of the clamping head 2 80. The clamping head 1 72 and the clamping head 2 80 are both conical block structures. The clamping head 1 72 and the clamping head 2 80 can cooperate to squeeze the two ends of the coil skeleton, and the axes of the coil skeleton, the clamping head 1 72 and the clamping head 2 80 are kept collinear under the support of the conical surface. ;

[0035] The working principle of the present technical solution is as follows: adjust the position of the skeleton driven assembly 8 according to the length of the coil skeleton, so that the clamping head 80 can press the coil skeleton onto the clamping head 72 under the elastic support of the support spring 85: use a wrench to loosen the bolts on the pipe clamp 84, and then slide and adjust the pipe clamp 84 to a suitable position. When the pipe clamp 84 moves, it pushes the support spring 85 to move the connecting plate 83. At this time, the pull rod 88 mounted on the bearing seat 86 is rotated to slide in the sliding sleeve 87; after the position of the pipe clamp 84 is adjusted, tighten the bolts on the pipe clamp 84 to lock the pipe clamp 84 on the guide rod 81; when installing the coil skeleton, hold the handle 89 to pull the pull rod 88 outward, and then press one end of the coil skeleton against the clamping head 72, and then release the handle 89. At this time, the support spring The spring 85 releases elastic potential energy to drive the clamping head 80 to move in the direction of the skeleton driving component 7, so that the clamping head 80 is pressed against the other end of the coil skeleton. At this time, the coil skeleton is centered and installed under the action of the conical clamping head 80 and the anti-slip protrusion 73, and the anti-slip protrusion 73 is elastically deformed after being squeezed, which effectively increases the friction between the coil skeleton and the coil skeleton, thereby ensuring the stability of the installation of the coil skeleton. When performing the winding operation, one end of the wire led out of the wire nozzle 5 is fixed on the coil skeleton, and the driving motor 71 is started to drive the clamping head 72 to rotate, thereby driving the coil skeleton to rotate. At the same time, the motor in the linear moving component 2 drives the wire nozzle 5 to move linearly, and the magnetic tensioner 4 maintains the tensioning force of the wire, so that the wire is effectively spirally wound on the coil skeleton.
