Technical Field

[0001] This utility model relates to the technical field of fixed beam gantry machining centers, and specifically to a positioning device for a fixed beam gantry machining center. Background Technology

[0002] The fixed-beam gantry machining center is a series of boring and milling machines with a movable worktable. It inherits the advantages of traditional gantry machine tools, such as strong frame rigidity, symmetrical structure, and strong stability. It adopts PRO / E three-dimensional design and finite element analysis to optimize the structure of moving parts and incorporates dynamic rigidity design concept and thermal symmetry design concept.

[0003] Existing fixed-beam gantry machining centers use various fixtures to clamp workpieces. However, these fixtures require bolts for positioning, making installation and disassembly cumbersome and height adjustment difficult, thus limiting their usability. Therefore, to overcome these shortcomings, we propose a positioning device for fixed-beam gantry machining centers. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application proposes a positioning device for a fixed beam gantry machining center. Through the above structure, this technical solution has the characteristics of wide application range and easy adjustment.

[0006] As a preferred embodiment of this utility model, the blocking mechanism includes a blocking block and a plurality of second bolts. The blocking block is located in the slot of the gantry worktable and is fixedly connected to the bottom of the support plate. The plurality of second bolts are located in the slot of the gantry worktable, and the top of the second bolts penetrates the support plate and is threaded with a nut.

[0007] As a preferred embodiment of this utility model, the adjustment mechanism includes a third bolt, which is threaded onto the side wall of the limiting chamber, and the side wall of the adjustment block is provided with a plurality of circular grooves that match the third bolt.

[0008] As a preferred embodiment of this utility model, several circular grooves are equidistantly distributed on the side wall of the adjusting block, and a pair of limiting chambers are symmetrically arranged about the central axis of the gantry worktable.

[0009] As a preferred embodiment of this utility model, each pair of electric telescopic rods is symmetrically arranged about the central axis of the limiting plate, and a pair of clamping plates is symmetrically arranged about the central axis of the gantry workbench.

[0010] As a preferred embodiment of this utility model, the cross-sectional length and width of the adjusting block are equal to the length and width of the inner cavity of the limiting chamber.

[0011] The beneficial effects of this utility model are: 1. By using the limiting chamber, adjusting block, clamping plate, electric telescopic rod and third bolt, when clamping the workpiece, adjust the height of the clamping plate up and down until the height of the clamping plate is appropriate. Tighten the third bolt into the round groove to fix the height of the adjusting block and clamping plate to adapt to workpieces of different sizes. Then place the workpiece between a pair of clamping plates and start the electric telescopic rod. The electric telescopic rod pushes the clamping plates to move until a pair of clamping plates clamp the workpiece, thereby improving the application range of the device. 2. By setting up the first bolt, clamping plate and limiting plate, when it is necessary to clamp workpieces of different shapes, unscrew the first bolt, remove the clamping plate, put the new clamping plate on the limiting plate, and then screw the first bolt back on to complete the replacement of the clamping plate, thereby improving the applicability of the device.
