Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically a safety protection net and its gantry machining center. Background Technology

[0002] The gantry machining center adopts a closed gantry structure (composed of double columns, crossbeams, and a top beam), which has higher rigidity and stability compared to traditional bed-type (C-type) machine tools. This structure can effectively disperse cutting forces and reduce vibration and deformation, making it particularly suitable for heavy cutting and machining of large workpieces.

[0003] Chinese invention patent CN116619123A, published on August 22, 2023, discloses a gantry machining center with a protective mechanism, including a gantry machining center body, a storage plate, casters, and protective components. A motor drives a first opening / closing threaded rod to rotate, which in turn drives a second opening / closing threaded rod to rotate via a connecting rod. The first opening / closing threaded rod moves a first opening / closing threaded ring, and the second opening / closing threaded rod moves a second opening / closing threaded ring. The first and second opening / closing threaded rings move in opposite directions, thereby causing two protective plates to move in opposite directions. This allows for easy adjustment of the protective plates' working state according to work requirements. The protective plates are opened when operators are operating at close range, i.e., when adjusting the machining structure, and closed when machining workpieces. This prevents debris from flying and injuring operators while observing the machining process from one side of the gantry machining center, thus improving safety.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing gantry machining center has good protection effect, but when loading and unloading materials in the gantry center, the movement path and range of the protective plate need to be transferred, which makes each loading and unloading operation troublesome and makes it impossible to quickly transfer the loading and unloading channel. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem that while existing gantry machining centers have good protective effects, the large movement path and range of the protective plate are required during loading and unloading, making each loading and unloading operation cumbersome and unable to achieve rapid transfer of the loading and unloading channel. This utility model provides a safety protection net and a gantry machining center thereof.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a safety protection net and a gantry machining center, comprising a counterweight tube; a lifting column is slidably inserted into the counterweight tube through an opening; multiple stepped shafts are fixedly connected to the upper end of the lifting column; a first arc tube is sleeved on the stepped shaft; a second arc tube is slidably inserted into the first arc tube; a third arc tube is slidably inserted into the end of the second arc tube; a fixing sleeve is sleeved on the first, second, and third arc tubes; a support column is fixedly connected to the fixing sleeve; and a protective net is sleeved between the support columns.

[0008] Furthermore, a blocking plate is detachably fixed to the lower end of the support column; a limiting cover plate is detachably fixed to the stepped shaft.

[0009] A gantry machining center: comprising the safety protection net described in any one of the above.

[0010] The safety protection net and its gantry machining center provided by this utility model have the following beneficial effects:

[0011] 1. This utility model changes the area of ​​the protection range formed by multiple protective nets by changing the angle and length of two sets of symmetrical first, second and third circular arc tubes, thereby adapting to different gantry machining centers. At the same time, the protection range can be adjusted according to the shape and position of the site, so that each processing can be safe and stable, and the adjustment of the protection range is simpler and more reliable.

[0012] 2. This utility model locks the two docking plates by inserting the locking cover plate into the opening of the docking plate, so that multiple protective nets form a circular tube that completely surrounds the gantry machining center. Thus, during processing, the gantry machining center can be protected in all directions, preventing the danger caused by flying parts. Attached Figure Description

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4 As shown, a safety protection net and its gantry machining center include a counterweight pipe 1 placed statically on the ground; a lifting column 2 is slidably inserted into the counterweight pipe 1 through an opening, allowing the height of the lifting column 2 to be adjusted to suit gantry machining centers of different heights or to meet different protection needs; multiple stepped shafts 3 are fixedly connected to the upper end of the lifting column 2; a first arc tube 4 is sleeved on the stepped shaft 3, allowing two first arc tubes 4 to rotate freely around the stepped shaft 3 to form a protective range, which can be adjusted according to the size of the gantry machining center; a second arc tube is slidably inserted into the first arc tube 4. Pipe 6; a third arc pipe 7 is slidably inserted into the end of the second arc pipe 6; a fixed sleeve 10 is sleeved on the first arc pipe 4, the second arc pipe 6 and the third arc pipe 7; a support column 11 is fixedly connected to the fixed sleeve 10; a protective net 12 is sleeved between the support columns 11. By changing the angle and length of the two sets of symmetrical first arc pipe 4, second arc pipe 6 and third arc pipe 7, the area of ​​the protection range formed by multiple protective nets 12 can be changed, thereby adapting to different gantry machining centers. At the same time, the protection range can be adjusted according to the shape and position of the site, so that each processing can be safe and stable, and the adjustment of the protection range is simpler and more reliable.

[0023] A blocking plate 13 is detachably fixed to the lower end of the support column 11; a limiting cover plate 5 is detachably fixed to the stepped shaft 3. The limiting cover plate 5 restricts the first arc tube 4 to the support column 11, so that the first arc tube 4 can only rotate around the support column 11 and cannot come out upward, thus making it more stable and safe in daily use.

[0024] The first circular arc tube 4, the second circular arc tube 6, and the third circular arc tube 7 are all fixed with magnetic blocks 14. Through the magnetic connection between the multiple magnetic blocks 14, the second circular arc tube 6 and the third circular arc tube 7 can maintain a certain stability when they are retracted, and will not easily loosen and affect transportation and movement.

[0025] The end of the third arc tube 7 is detachably fixed with a docking plate 8; a locking cover plate 9 is inserted into the opening of the docking plate 8. By inserting the locking cover plate 9 into the opening of the docking plate 8, the two docking plates 8 are locked, so that multiple protective nets 12 form a circular tube, completely surrounding the gantry machining center. Thus, during processing, the gantry machining center can be protected in all directions, preventing the danger caused by parts splashing.

[0026] The lower end of the counterweight pipe 1 is fixed with a flange plate 15. Bolts are passed through the flange plate 15, so that it can be fixed to the pre-embedded ground pile, or it can be fixed to the opening in the ground with expansion bolts, so that it is more stable after fixing and can be moved and used frequently for a long time.
