Description

Technical Field

[0001] The utility model relates to the technical field of numerical control processing, and relates to a numerical control processing plate material transfer hanger. Background Art

[0002] In the semi-automated production process, the transfer and handling of large workpieces usually requires the use of special lifting equipment to complete the workpiece transportation between various production lathes;

[0003] Traditional sheet metal lifting equipment used for CNC machining is usually clamped and lifted with a clamping cage and lifting ear structure. However, due to the large weight of the large sheet metal itself, there is usually a certain degree of movement in the lifting direction before and after lifting. The fixed clamping structure cannot effectively buffer the axial force before and after lifting, which can easily cause vibration and damage to the lifted sheet metal during lifting and loading and unloading, posing a safety hazard.

DETAILED DESCRIPTION

[0020] See also Figure 1-3 , the embodiments of the utility model are further described;

[0021] A CNC machining plate material transfer lifting device, comprising a lifting cage 1 and a lifting lug 4, wherein four lifting lugs 4 are provided and the lifting lugs 4 are relatively annularly distributed at one end of the lifting cage 1, a cable drum frame 2 is sleeved and fixed on the lifting cage 1, and a cable wheel 3 matching the position of the lifting lug 4 is hingedly provided on the cable drum frame 2, and a steel cable 5 is connected between the cable wheel 3 and the lifting lug 4;

[0022] A cross ring frame 8 is provided in the cable drum frame 2, and the cable wheel 3 is mounted on the cross ring frame 8. A vertical drum frame 7 is axially provided in the cross ring frame 8, and a sliding sleeve 10 that is slidably matched with the vertical drum frame 7 is fixed on the cross ring frame 8;

[0023] A main shaft 6 is provided between the cage 1 and the cable drum frame 2. A suspension hole is provided on the main shaft 6 extending to the outer end of the cage 1, and the other end of the main shaft 6 is connected with the vertical drum frame 7. The vertical drum frame 7 is slidably fitted with a support shaft 11 relative to one end of the main shaft 6, and a compression spring coil is filled in the end of the support shaft 11 close to the vertical drum frame 7, and the other end of the support shaft 11 is fixed to the cage 1.

[0024] The hoisting device structure uses the hoist cage 1 as the clamping and fixing end of the hoisting equipment and the structure, wherein the suspension hole of the main shaft 6 is used as a specific clamping structure, and the entire hoisting structure is axially maintained on the main shaft 6 and the vertical drum frame 7, and the cross ring frame 8 erected on the vertical drum frame 7 is used as the erecting end of the cable wheel 3, and the cable wheel 3 is connected and fixed with the lifting lugs 4 at various positions through the steel wire cable 5, and is clamped and fixed by the clamping connection between the lifting lugs 4 and the corners of the sheet material, and is hoisted and transferred in combination with the hoisting equipment;

[0025] Among them, in the lifting and loading and unloading gaps before and after lifting, the sliding sleeve 10 structure between the cross ring frame 8 and the vertical drum frame 7 can make the cross ring frame 8 slide axially along the vertical drum frame 7 in the direction of the lifting force, and when the lifting pulling force in one direction is too large, after the sliding sleeve 10 moves to the limit position at one end, the support shaft 11 is axially compressed through the vertical drum frame 7, so that the compression spring coil at the end of the support shaft 11 is compressed, and the reaction force is used to counteract and buffer the axial structure of the vertical drum frame 7 and the cross ring frame 8, that is, the end of the wire cable 5 connected to the cable wheel 3 is axially buffered, so as to avoid the excessive weight of the sheet material and the instantaneous traction force during lifting and loading and unloading, which causes the sheet material to vibrate and the lifting is unstable, thereby improving the stability and safety of the lifting device during lifting.

[0026] Preferably, a crank shaft 9 is hingedly provided between the cable wheel 3 and the cross ring frame 8, and the bottom of the axial inclination angle of the crank shaft 9 is counterweighted by a filling material block. The crank shaft 9 serves as a rotating matching structure between the cable wheel 3 and the cross ring frame 8, and the counterweight of the counterweight block can be used to maintain the axial angle of the crank shaft 9 at the bottom to maintain the inclination angle of the cable wheel 3 and the wire cable 5.

[0027] Preferably, the outer edges of the through ends of the cable drum frame 2 and the cross ring frame 8 are formed with longitudinal strip tracks, and the strip tracks are used to cooperate with the axial sliding action of the cross ring frame 8 to improve the axial displacement accuracy of the cross ring frame 8.

[0028] Preferably, a shaft handle head 12 is protruding from the side edge of the support shaft 11, and a track groove is longitudinally opened on the side of the vertical cylinder frame 7 close to the shaft handle head 12. The axial movable position between the support shaft 11 and the vertical cylinder frame 7 is controlled by the radially arranged shaft handle head 12 and the matching track groove, thereby ensuring the displacement accuracy between the vertical cylinder frame 7 and the support shaft 11.

[0029] Preferably, the lifting ear 4 is a vertical concave lifting ear, and a cable segment 13 is axially passed through and fixed between one end of the lifting ear 4 and the wire cable 5, and a support handle 14 longitudinally matching the cable segment 13 is hingedly provided at the other end of the lifting ear 4. The vertical concave lifting ear with a side opening utilizes the groove therein to perform a snap-fit ​​clamping with the edge of the sheet material, wherein the support handle 14 serves as the supporting end between the bottom of the lifting ear 4 and the bottom surface of the sheet material to maximize the self-weight of the sheet material during lifting. At the same time, the hinged activity of the hinged structure of the support handle 14 can adapt to the step height of the bottom surface of the sheet material, thereby improving the applicability of the lifting device.

[0030] On the basis of the above, a hinge shaft 15 is internally provided at the hinged end of the support handle 14 and the lifting ear 4, and a counterweight 16 is installed on the side of the lifting ear 4 relative to the end, and the counterweight 16 is connected to the hinge shaft 15. Through the connection between the hinge shaft 15 and the counterweight 16, the relative position of the counterweight 16 and the position of the support handle 14 are utilized to form a relatively horizontal balanced hinge inclination angle, so as to maintain the balance of the lifting ear 4 when the support handle 14 contacts the bottom surface of the sheet metal.

[0031] The implementation method of the device is that the suspension hole of the main shaft 6 is used to clamp and fix with the lifting end of the lifting equipment, the cable wheel 3 is connected and fixed with the lifting ears 4 at various positions through the steel wire cable 5, and specifically, the opening groove on the side of the lifting ear 4 is used to clamp with the edge of the plate in a snap-fit ​​manner, wherein the support handle 14 serves as the supporting end of the bottom of the lifting ear 4 and the bottom surface of the plate, and is combined with the lifting equipment for lifting and transfer. After being clamped and fixed with the plate, the lifting and loading and unloading clearances before and after lifting can be made by the sliding sleeve 10 structure between the cross ring frame 8 and the vertical cylinder frame 7 to make the cross ring frame 8 slides axially along the vertical drum frame 7 in the direction of the lifting force, and when the lifting pulling force in one direction is too large, after the sliding sleeve 10 moves to the limit position at one end, the support shaft 11 is axially compressed through the vertical drum frame 7, and the compression spring coil at the end of the support shaft 11 is compressed, so as to use the reaction force to counteract and buffer the axial structure of the vertical drum frame 7 and the cross ring frame 8, that is, to axially buffer the end of the wire cable 5 connected to the cable wheel 3, so as to avoid the excessive weight of the sheet material and the instantaneous traction force during lifting and loading and unloading, which may cause the sheet material to vibrate and the lifting is unstable.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
