Description

Technical Field

[0001] The utility model relates to the field of metal processing equipment, in particular to a semi-protective structure of a large gantry processing center. Background Art

[0002] Gantry machining centers are large-scale processing equipment with a portal frame structure consisting of two columns and a top beam. The workpieces processed by gantry machining centers are generally large. In particular, large gantry machining centers often require a crane or other lifting device to load and unload workpieces. Therefore, it is not appropriate to install enclosed protective structures around the worktable of large gantry machining centers. However, if the sides of the gantry machining center's worktable are not protected, metal chips can easily splash onto the operator during processing, causing safety accidents. To reduce safety risks, some people currently use protective plates temporarily fixed to the sides of the worktable to block them. Although this method can prevent splashing, the protective plates need to be removed each time the workpiece is hoisted, which is not very convenient to operate. In view of this, if there is a semi-protective shielding structure that can be fixed to the columns of the gantry machining center, it can not only prevent metal chips from splashing and injuring people during processing, but also be conveniently folded when not in use, thereby reducing safety risks during operation and improving the convenience of protective operations. This is the problem to be solved in this case. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model discloses a semi-protective structure of a large gantry machining center, comprising a first protective plate, a second protective plate and a third protective plate, wherein the first protective plate, the second protective plate and the third protective plate are arranged in a row in sequence and are hinged by a hinge, the first protective plate is fixedly connected to a rotating shaft on the other side away from the hinge and a rotating sleeve is sleeved on the rotating shaft, the rotating sleeve can be fixed to the column of the gantry machining center, a rotating cylinder is provided on the rotating shaft, the rotating shaft can rotate around the rotating sleeve and can drive the first protective plate to rotate, a first cylinder and a connecting rod are provided between the first protective plate and the second protective plate, and a second cylinder is provided between the second protective plate and the third protective plate. The semi-protective structure of a large gantry machining center of the present invention arranges the first protective plate, the second protective plate and the third protective plate in sequence and hinges the adjacent edges to each other, and utilizes the first cylinder and the second cylinder to drive the second protective plate and the third protective plate to flip over, so that the first protective plate, the second protective plate and the third protective plate can be in an "I" state for protection and shielding, and can also be in a "Z" state for folding; a rotating shaft, a rotating sleeve and a rotating cylinder are provided on the other side of the first protective plate, and the rotating cylinder is utilized to drive the first protective plate to rotate so that the first protective plate, the second protective plate and the third protective plate can be closer to the column of the gantry machining center when not in use, thereby reducing the safety risks during the operation of the gantry machining center and improving the convenience of the protective operation.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] The cam is connected to the second guard plate by a hinge, and the cam is connected to the first guard plate by a hinge.

[0006] A rotary cylinder is provided on the top of the rotating shaft. The rotary cylinder can drive the rotating shaft to rotate. The rotation angle range of the rotary cylinder can be set to 0° to 90°. The rotary cylinder is fixed to the column of the gantry machining center.

[0007] The rotating sleeve is composed of two pieces, which are respectively arranged at the upper half and the lower half of the rotating shaft.

[0008] There are four hinges, two of which are placed at the upper and lower halves of the junction between the first protective plate and the second protective plate, and the other two hinges are placed at the upper and lower halves of the junction between the second protective plate and the third protective plate.

[0009] The hinge is a torque hinge. The hinge placed between the first protective plate and the second protective plate can promote the outward flipping of the second protective plate with the assistance of its internal torsion spring. After flipping outward, the second protective plate can be in an "L" shape with the first protective plate; the hinge placed between the second protective plate and the third protective plate can promote the inward flipping of the third protective plate with the assistance of its internal torsion spring. After flipping inward, the third protective plate can be in an "∧" shape with the second protective plate.

[0010] The first cylinder and connecting rod are respectively placed horizontally on the upper part of the inner side surfaces of the first protective plate and the second protective plate. The cylinder rod of the first cylinder is hinged to one end of the connecting rod. The cylinder body of the first cylinder is hinged to the first protective plate by a hinge support, and the other end of the connecting rod is hinged to the second protective plate by a hinge support.

[0011] The second cylinder is placed horizontally on the upper inner side surfaces of the second and third protective plates. The cylinder rod of the second cylinder is connected to the third protective plate by a universal hinge joint, and the cylinder body of the second cylinder is hinged to the second protective plate by a hinge support.

[0012] Furthermore, a transparent observation window is provided in the middle of the second protective plate.

[0013] From the above description, it can be seen that the semi-protective structure of a large gantry machining center provided by the utility model has the following advantages: first, the first protective plate, the second protective plate and the third protective plate are arranged in sequence and the adjacent edges are hinged to each other, and the first cylinder and the second cylinder are used to drive the second protective plate and the third protective plate to flip, so that the first protective plate, the second protective plate and the third protective plate can be in an "I" state for protection and shielding, and can also be in a "Z" state for folding; second, a rotating shaft, a rotating sleeve and a rotating cylinder are provided on the other side of the first protective plate, and the rotating cylinder is used to drive the first protective plate to rotate so that the first protective plate, the second protective plate and the third protective plate can be closer to the column of the gantry machining center when not in use, thereby reducing space occupation. The semi-protective structure of a large gantry machining center of the utility model can reduce the safety risks during the operation of the gantry machining center and improve the convenience of protective operations. The utility model has a reasonable design, a simple structure, low cost and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS
