Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, and relates to a machined workpiece anti-jamming 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] The sling is usually fixed with a lifting lug by a cable to clamp and fix the workpiece to be transferred, so as to lift and transfer the workpiece according to the lifting position and height of the lifting equipment. Due to the omnidirectional displacement of the sling during the lifting process, horizontal oscillation of the sling and the lifting lug is inevitable, causing the displacement of the connection point between the lifting lug and the sling. The connection ends of traditional slings and lifting lugs usually adopt a relatively fixed axial track structure, which is prone to jamming of the connection point during the lifting longitudinal displacement of the sling and the lifting lug, resulting in imbalance of the connection points of the lifting lugs at each corner, thereby affecting the stability of the horizontal structure of the sling during lifting.

DETAILED DESCRIPTION

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

[0021] A machined workpiece anti-jamming hanger comprises a hanging cage 1, a hanging plate 2 and a hanging ear rail frame 3, wherein the hanging cage 1 is a cage frame structure with an upper opening, the hanging plate 2 is relatively arranged at the open end of the hanging cage 1, at least four hanging ear rail frames 3 are arranged, and the hanging ear rail frames 3 are distributed in a ring shape and embedded and fixed with the hanging cage 1;

[0022] A lifting head 4 is fixed on the top of the hanging plate 2, and a hanging tube 6 is provided at the other end of the hanging plate 2 extending toward the inside of the cage 1, a mounting plate frame 7 is sleeved and fixed at the bottom end of the hanging tube 6, and a hanging lug head 8 is extended to each hanging lug rail frame 3 by the mounting plate frame 7, and roller seats 13 are rotatably provided on both sides of the hanging lug head 8, and the roller seats 13 are slidably matched with the hanging lug rail frame 3;

[0023] A vertical axis rod 5 is fixedly arranged at the bottom of the cage 1, and the hanging tube tube 6 is axially matched with the vertical axis rod 5, and the vertical axis rod 5 and the hanging tube tube 6 are connected through and slidably matched.

[0024] The hoisting device structure uses the axially arranged hanging tube 6 and the mounting disc frame 7 as the axially movable frame of the hanging ear head 8. The structure uses the hanging disc 2 and the lifting head 4 as the connecting ends of the hanging tube 6 and the lifting equipment, wherein the axial sliding of the hanging tube 6 is axially limited by the vertical shaft rod 5 arranged at the bottom to maintain the horizontal position of the hanging tube 6 and the mounting disc frame 7, improve the horizontal stability during sliding, and at the same time cooperate with the roller seats 13 at both ends of the hanging ear head 8 to slide with the hanging ear rail frame 3, while further maintaining the longitudinal sliding position of the hanging ear head 8 through the groove structure of the hanging ear rail frame 3, ensuring the smoothness of the roller seat 13 and the hanging ear rail frame 3 to avoid jamming;

[0025] The sling structure slides and limits the axial movement of the entire sling at multiple axial positions through the sling tube 6 and the vertical shaft rod 5, the sling head 8 and the sling rail frame 3, thereby ensuring the axial stability and movement accuracy of the sling during the lifting process, effectively avoiding the jamming of the sling, and improving the practicality of the sling.

[0026] Preferably, a sliding sleeve 11 is installed at the opening of the cage 1, and the sliding sleeve 11 is slidably matched with the hanging tube 6. The sliding sleeve 11 fixed to the cage 1 is further used to provide structural support for the axial sliding of the hanging tube 6 by utilizing the cage 1 structure, and the axial movement of the hanging tube 6 is further limited, thereby improving the active structural stability of the sling.

[0027] Preferably, the mounting frame 7 is a spliced ​​frame with a trapezoidal cross-section, and the ear head 8 is relatively hingedly arranged at the oblique end of the mounting frame 7. The trapezoidal mounting frame 7 structure is adopted, and its arched end can effectively support the installation position of the ear head 8, that is, ensure the horizontal position stability of the mounting frame 7.

[0028] Preferably, a support frame plate 10 is fixedly arranged between the bottom of the cage 1 and the vertical axis rod 5, and a spring seat 9 is arranged between the support frame plate 10 and the mounting disc frame 7. The spring seat 9 arranged on the support frame plate 10 can be used to buffer the axial movable structure of the mounting disc frame 7 when the hanging tube 6 and the mounting disc frame 7 move to the bottom limit position, so as to avoid damage to the hanging tube 6 and the vertical axis rod 5 caused by the instantaneous force of the lifting activity during lifting.

[0029] Preferably, an L-shaped rail frame 12 is symmetrically arranged on the inner edge of the lifting ear rail frame 3, and the L-shaped rail frame 12 is slidably matched with the side edge of the lifting ear head 8 in an embracing manner. The embracing structure of the L-shaped rail frame 12 is used to ensure the longitudinal matching accuracy with the lifting ear head 8, and at the same time, the lifting ear head 8 is laterally limited to improve the horizontal stability of the lifting ear head 8.

[0030] On the basis of the above, a matching slide bar 14 is slidably arranged between the side edge of the lifting ear head 8 and the edge of the L-shaped rail frame 12, and the matching slide bar 14 and the L-shaped rail frame 12 are an I-shaped docking structure, and the sliding matching accuracy of the lifting ear head 8 and the L-shaped rail frame 12 is further improved through the I-shaped docking cooperation between the L-shaped rail frame 12 and the matching slide bar 14.

[0031] The implementation method of the device is that the sling structure uses the axially arranged bobbin tube 6 and the mounting disc frame 7 as the axially movable frame of the lifting ear head 8, and its structure uses the lifting plate 2 and the lifting head 4 as the connecting ends of the bobbin tube 6 and the lifting equipment. During the lifting activity, the lifting head 4 is axially pulled by the lifting equipment to drive the lifting plate 2 and the bobbin tube 6 to slide relative axially in the cage 1 to adjust the horizontal height of the mounting disc frame 7 relative to the cage 1, wherein the axial sliding of the bobbin tube 6 will be axially limited by the vertical shaft rod 5 arranged at the bottom to maintain the horizontal position of the bobbin tube 6 and the mounting disc frame 7, and at the same time, the lifting ear head 8 on the mounting disc frame 7 serves as the connecting structure of the external lifting ear of the sling, and when the mounting disc frame 7 slides axially, the lifting ear head 8 will synchronously use the roller seat 13 to roll in the lifting ear rail frame 3 to cooperate with the mounting disc frame 7 to adjust the axial height position of the lifting ear head 8.

[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.
