Description

Technical Field

[0001] The utility model relates to the field of gantry brackets, in particular to a gantry bracket for a machining center. Background Art

[0002] A gantry machining center refers to a machining center in which the spindle axis is set vertically to the worktable. It is mainly suitable for machining large parts. The gantry bracket is the main component of the gantry machining center and plays a load-bearing role. The gantry bracket consists of a crossbeam and two columns.

[0003] At present, a Chinese utility model with announcement number CN216126822U discloses a gantry bracket for a gantry machining center, including a pair of columns, a crossbeam, and a fixed column. Several grooves are provided at intervals on opposite sides of the columns, and several shock-absorbing columns are provided on the inner surfaces of the grooves. An anti-collision plate is provided at one end of the shock-absorbing column away from the column. The utility model protects the column by providing the anti-collision plate, and cooperates with the shock-absorbing column to absorb the impact force, so as to improve its service life.

[0004] To sum up, although the gantry bracket can achieve the purpose of installing and supporting processing equipment, there are still certain problems when using it. For example, the beams and columns of the gantry bracket are installed by screwing bolts. In order to ensure the stability of the fixation, a large number of bolts are required, and the installation takes a lot of time. After long-term use, the bolts are easily unable to be removed due to stress or rust. At the same time, the gantry bracket lacks a structure for adjusting the height of the beam. After installation, the height of the beam is fixed, so that the height of the processing equipment installed on the beam is fixed with the workpiece on the work surface. When the height of the workpiece is higher than the height of the gantry bracket, it cannot be processed, and the applicability is poor. Utility Model Content

[0005] The utility model aims to provide a gantry bracket for a machining center, which has the advantages of convenient installation and height adjustment.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a gantry bracket for a machining center, comprising a cross beam, a first vertical beam is symmetrically arranged at the bottom of the cross beam, a limiting groove is symmetrically opened on the top of the cross beam, a limiting block inserted into the limiting groove is integrally processed on the top of the first vertical beam, a locking groove connected to the limiting groove is symmetrically opened on the top of the cross beam, a locking block inserted into the limiting block is arranged inside the locking groove, a second vertical beam is arranged at the bottom of the first vertical beam, a hydraulic cylinder is embedded in the top of the second vertical beam, the output end of the hydraulic cylinder is fixedly sleeved with the bottom of the first vertical beam, a guide rod is bolted to the top of the second vertical beam, and the guide rod is slidably connected to the first vertical beam.

[0007] By adopting the above technical scheme, the utility model opens a limiting groove on the cross beam, and installs a limiting block on the first vertical beam. When the limiting block is inserted into the limiting groove, the locking block inside the locking groove is locked into the limiting block, and the locking end of the locking block limits the limiting block, so that the first vertical beam and the cross beam are firmly fixed together, which is convenient for installation and ensures stability. A second vertical beam is designed at the bottom of the first vertical beam, and a hydraulic cylinder is installed on the second vertical beam. When the height of the cross beam needs to be adjusted, it only needs to start the hydraulic cylinder to drive the first vertical beam to adjust the height. The two first vertical beams adjust the height of the cross beam, so that the height of the workpiece is no longer limited to a height lower than the gantry bracket, thereby improving applicability.

[0008] The utility model is further configured as follows: a mounting groove is provided on the front side of the cross beam, and the mounting groove is used in conjunction with an external screw rod.

[0009] The above technical solution is adopted to facilitate the installation of the external screw rod.

[0010] The utility model is further configured as follows: a guide groove is provided on the front side of the cross beam, and the guide groove is used in conjunction with an external processing machine mounting seat.

[0011] The above technical solution is adopted to facilitate the sliding guidance of the mounting seat of the external processing machine.

[0012] The utility model is further configured as follows: a sliding block is symmetrically bolted to the positioning block, and a sliding groove used in conjunction with the sliding block is provided inside the positioning groove.

[0013] The above technical solution is adopted to slide and limit the positioning block.

[0014] The utility model is further configured as follows: a slide bar slidably connected to the crossbeam is bolted on the positioning block, and a return spring used in conjunction with the positioning block is sleeved on the surface of the slide bar.

[0015] By adopting the above technical solution, the positioning block is limited in sliding and a reverse elastic force is provided.

[0016] The utility model is further configured as follows: a fixing seat is bolted to the bottom of the second vertical beam, and a threaded hole is provided on the fixing seat.

[0017] The above technical solution is adopted to facilitate the installation and fixing of the gantry bracket on the gantry workbench.

[0018] The utility model is further configured as follows: a guide block is bolted on the first vertical beam, and a guide seat slidably connected to the guide block is symmetrically bolted on the second vertical beam.

[0019] The above technical solution is adopted to limit the position of the first vertical beam.

[0020] The utility model is further configured as follows: a positioning block is symmetrically bolted to the top of the first vertical beam, and a positioning slot used in conjunction with the positioning block is provided at the bottom of the cross beam.

[0021] The above technical solution is adopted to limit the position of the beam.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model provides a limiting groove on the cross beam, and installs a limiting block on the first vertical beam. When the limiting block is inserted into the limiting groove, the clamping block inside the clamping groove is clamped into the limiting block, and the clamping end of the clamping block limits the limiting block, so that the first vertical beam and the cross beam are firmly fixed together, which is convenient for installation and ensures stability;

[0024] 2. The utility model is designed with a second vertical beam at the bottom of the first vertical beam, and a hydraulic cylinder is installed on the second vertical beam. When the height of the cross beam needs to be adjusted, it is only necessary to start the hydraulic cylinder to drive the first vertical beam to adjust the height. The two first vertical beams adjust the height of the cross beam, so that the height of the workpiece is no longer limited to a height lower than the gantry bracket, thereby improving applicability.
