Description

Technical Field

[0001] This utility model relates to the field of gantry machining support technology, and in particular to a gantry machining support that is easy to install. Background Technology

[0002] The gantry machining support is the core support structure of a gantry machining center. It adopts a portal frame design and consists of a crossbeam, columns, a base, and reinforcing components. The crossbeam, as the main load-bearing component, is typically equipped with guide rails to support the machining head or crane, enabling movement along the X-axis. The columns and base are fixed with bolts or welding to form a stable foundation. Some models also feature support rods and guide grooves to enhance structural rigidity. Its working principle is based on three-axis linkage control: the crossbeam moves along the X-axis, the machining head moves along the Y-axis (crossbeam direction), and the Z-axis (vertical direction) in a coordinated manner to complete the precision machining of complex curved surfaces. Gantry machining supports are widely used in aerospace, automotive manufacturing, mold processing, and other fields, and are particularly suitable for machining large and heavy parts.

[0003] Traditional gantry processing supports often use bolts to rigidly connect the beams and columns, requiring multiple people to work together to position and tighten them. The beam level needs to be adjusted using multiple layers of shims, which increases assembly time. The columns and bases are made using welding or integral casting processes, which cannot achieve quick disassembly and assembly. When the gantry is moved, the welding points need to be cut, and the accuracy decreases after reassembly, requiring secondary adjustment and reducing assembly efficiency. Utility Model Content

[0004] Based on this, it is necessary to address the issues that the beams and columns are mostly connected by bolts, which requires multiple people to work together to complete the positioning and fastening. The beam level needs to be adjusted by multiple layers of shims, which increases the assembly time. The columns and bases are made by welding or integral casting, which cannot achieve quick disassembly and assembly. When the gantry is moved, the welding points need to be cut, and the accuracy decreases after reassembly, requiring secondary adjustment and reducing assembly efficiency. Therefore, it is necessary to provide a gantry processing bracket that is easy to install.

[0005] A gantry processing support that is easy to install includes: a crossbeam, support blocks fixedly connected to the lower sides of the crossbeam, columns fixedly connected to the lower sides of the two support blocks, and bases fixedly connected to the lower sides of the two columns.

[0006] The support rods are provided in two parts, and the two ends of the two support rods are respectively fixedly connected to the column and the outer wall of the base;

[0007] A reinforcing component is provided on both sides of the column and located below both sides of the crossbeam to improve the support stability of the crossbeam.

[0008] In one embodiment, reinforcing ribs are fixedly connected to both sides of the crossbeam, and the two reinforcing ribs extend to both sides.

[0009] In one embodiment, the middle of the crossbeam extends downward and is fixedly connected to a guide rail, which is used to guide the crane.

[0010] In one embodiment, the two support blocks are bolted to the lower sides of the crossbeam, and the two support blocks are respectively fitted onto the top surfaces of the two columns.

[0011] In one embodiment, fixing blocks are fixedly connected to both sides of the support rod, and the two fixing blocks are respectively fixedly connected to the column and the outer wall of the base with bolts.

[0012] In one embodiment, guide grooves are provided on both sides of the column and the base, and multiple fixing blocks slide along both sides of the guide grooves respectively.

[0013] In one embodiment, the reinforcing component includes reinforcing blocks fixedly disposed on both sides of the column, connecting blocks fixedly connected to both sides of the reinforcing rib, and a connecting plate fixedly connected between the connecting blocks and the reinforcing blocks.

[0014] In one embodiment, the connection surface between the crossbeam and the support block is provided with a positioning hole, and a positioning pin is embedded in the positioning hole to achieve rapid centering and positioning of the crossbeam and the support block. Beneficial effects

[0015] 1. The crossbeam is rigidly connected to the support blocks on both sides by high-strength bolts. The support blocks adopt a trapezoidal cross-section design, with the bottom nested in the conical positioning groove at the top of the column, achieving quick and accurate alignment. The column and the base are connected by flange bolts. The main body of the base is a box-shaped welded structure with internal stiffeners distributed in a star pattern, which improves torsional rigidity. Heavy-duty load-bearing wheels are installed on both sides of the base. The wheels are forged from alloy steel and the surface is carburized and quenched. The wheel hubs integrate double-row tapered roller bearings and are combined with solid rubber treads to effectively absorb ground vibration. The support rod adopts a two-section support structure, with both ends connected to the column and base by quick-release pins, which improves the installation efficiency of the support system. The entire bracket adopts a weld-free design, and all connecting parts can be quickly installed and removed with power tools. Combined with the folding heavy-duty load-bearing wheels under the base, the total time from unfolding to putting the equipment into use is reduced, and the installation efficiency is improved compared to the traditional structure.

[0016] 2. The two support blocks are rigidly connected to the lower sides of the crossbeam via hydraulic pre-tightening bolts. The bolt holes adopt a conical guide design, which can achieve unilateral tightening with a torque wrench. The bottom of the support block is embedded in the conical positioning groove at the top of the column. The inner surface of the groove is hard chrome plated. The fit clearance is controlled within a certain range. With the assistance of an infrared positioning device, quick centering can be achieved. The fixing blocks welded at both ends of the support rod adopt a dovetail slider structure, which forms a precise fit with the C-shaped guide groove on the outer wall of the column and base. The surface of the slider is coated with molybdenum disulfide solid lubricant, which reduces the insertion force. The fixing blocks are quickly locked by quick-release pins. The pins are equipped with a double spring anti-loosening mechanism, which reduces the pre-tightening force attenuation rate under vibration conditions, shortens the total installation time of the support system, and improves efficiency compared with traditional welded structures.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-5 This invention describes an easy-to-install gantry machining support.

[0027] In one embodiment, an easy-to-install gantry processing support includes: a crossbeam 100, support rods 301, and reinforcing components 500. Support blocks 200 are fixedly connected to the lower sides of the crossbeam 100, columns 300 are fixedly connected to the lower sides of the two support blocks 200, and bases 400 are fixedly connected to the lower sides of the two columns 300. Two support rods 301 are provided, and the two ends of the two support rods 301 are fixedly connected to the outer walls of the columns 300 and the bases 400, respectively. The reinforcing components 500 are provided on both sides of the columns 300 and located below both sides of the crossbeam 100 to improve the support stability of the crossbeam 100.

[0028] In this embodiment, the two sides of the crossbeam 100 are rigidly connected to the support block 200 by high-strength bolts. The support block 200 adopts a trapezoidal cross-section design, and its bottom is nested in the conical positioning groove at the top of the column 300 to achieve rapid and accurate alignment.

[0029] The column 300 and the base 400 are connected by a flange bolt assembly. The main body of the base 400 is a box-shaped welded structure with internal stiffeners distributed in a star pattern, which improves torsional rigidity. Heavy-duty load-bearing wheels are installed on both sides of the base 400. The wheel body is forged from alloy steel and the surface is carburized and quenched. The rated load of a single wheel is 12 tons, which is suitable for wide temperature range conditions from -30℃ to 60℃. The wheel hub integrates double-row tapered roller bearings and is equipped with 20mm thick solid rubber tread to effectively absorb ground vibration.

[0030] The support rod 301 adopts a two-section support structure. Both ends are connected to the column 300 and the base 400 through quick-release pins, which improves the installation efficiency of the support system. The entire bracket adopts a weld-free design, and all connecting parts can be quickly installed and removed with power tools. Combined with the folding heavy-duty load-bearing wheels 600 under the base 400, the total time from unfolding to putting the equipment into use is reduced, and the installation efficiency is improved compared with the traditional structure.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, reinforcing ribs 101 are fixedly connected to both sides of the crossbeam 100, and the two reinforcing ribs 101 extend to both sides. The middle part of the crossbeam 100 extends downward and is fixedly connected to a guide rail 102, which is used to guide the crane.

[0032] In this embodiment, reinforcing ribs 101 are welded to both sides of the crossbeam 100. They are made of low alloy steel and are bent into shape, forming a closed ring structure with the crossbeam 100 body, which improves the bending modulus. The ends of the reinforcing ribs 101 extend to the top of the column 300 and form a mechanical transmission path with the side plate of the column 300 through pins. A high-precision linear guide rail 102 is integrated in the middle of the crossbeam 100. The rail surface is treated with induction hardening and is equipped with a four-row ball block slider. The bottom of the guide rail 102 is provided with a centralized lubrication oil circuit, which can realize long-term maintenance-free operation and facilitate the crane to be driven on the guide rail 102.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the two support blocks 200 are bolted to the lower sides of the crossbeam 100, and the two support blocks 200 are respectively fitted onto the top surfaces of the two columns 300. The two sides of the support rod 301 are fixedly connected to the fixing blocks 302, and the two fixing blocks 302 are bolted to the outer walls of the column 300 and the base 400 respectively.

[0034] In this embodiment, the two support blocks 200 are rigidly connected to the lower sides of the crossbeam 100 via hydraulic pre-tightening bolts. The bolt holes adopt a conical guide design, which can achieve unilateral tightening with a torque wrench. The bottom of the support block 200 is embedded in the conical positioning groove at the top of the column 300. The inner surface of the groove is plated with hard chrome, and the fit clearance is controlled within a certain range. With the assistance of an infrared positioning instrument, quick centering can be achieved. The fixing blocks 302 welded at both ends of the support rod 301 adopt a dovetail slider structure, which forms a precise fit with the C-shaped guide groove 401 on the outer wall of the column 300 and the base 400. The slider surface is coated with molybdenum disulfide solid lubricant, which reduces the insertion force. The fixing blocks 302 are quickly locked by quick-release pins. The pins are equipped with a double spring anti-loosening mechanism, which reduces the pre-tightening force attenuation rate under vibration conditions, shortens the total installation time of the support system, and improves efficiency compared with traditional welded structures.

[0035] like Figure 3 , Figure 4 and Figure 5As shown, guide grooves 401 are provided on both sides of the column 300 and the base 400. Multiple fixing blocks 302 slide along both sides of the guide grooves 401 respectively. The reinforcing component 500 includes reinforcing blocks 502 fixedly disposed on both sides of the column 300. Connecting blocks 503 are fixedly connected to both sides of the reinforcing rib 101. Connecting plate 501 is fixedly connected between the connecting block 503 and the reinforcing block 502. The connecting surface of the crossbeam 100 and the support block 200 is provided with positioning holes 201. Positioning pins 202 are embedded in the positioning holes 201 to achieve quick centering and positioning of the crossbeam 100 and the support block 200.

[0036] In this embodiment, the guide grooves 401 on both sides of the column 300 and the base 400 adopt a dovetail trapezoidal cross-section design. The inner surface of the groove is coated with a titanium alloy wear-resistant layer with a hardness of HV800. Combined with the embedded slide rail structure of the fixing block 302, the repeatability of positioning accuracy is achieved. The connecting plate 501 of the reinforcing component 500 is forged from aerospace-grade aluminum alloy and the surface is anodized. It is connected to the reinforcing block 502 and the connecting block 503 by double-headed high-strength bolts to form a pre-tightening connection. The bolt holes adopt a spiral hole expansion process to distribute the force evenly. The positioning pin 202 embedded in the positioning hole 201 adopts a double conical surface structure. When inserted, it achieves automatic centering by gravity guidance. Combined with the laser alignment indicator, the docking time between the crossbeam 100 and the support block 200 is shortened.

[0037] Working principle:

[0038] During installation, the base 400 is moved to the designated position by heavy-duty load-bearing wheels. After unfolding, it is locked by the hydraulic outriggers of the load-bearing wheels. The column 300 is connected to the base 400 by flange bolts. The cross-shaped ribs inside the base 400 provide anti-torsional support. The support block 200 is nested with the top of the column 300 using the bottom conical positioning groove. Automatic centering is achieved with the assistance of an infrared positioning device. The hydraulic pre-tightening bolts are locked with a preset torque, reducing the installation time on one side.

[0039] The dovetail-shaped slider of the support rod 301 is inserted along the guide groove 401. The molybdenum disulfide coating reduces frictional resistance, and the quick-release pin ensures stable preload under vibration conditions. The connecting plate 501 of the reinforcing component 500 is rigidly connected to the reinforcing block 502 and the connecting block 503 through spiral expanded hole bolts, forming a mechanical transmission path between the beam 100 and the column 300, thus improving the bending modulus. The guide rail 102 adopts a four-row ball-bearing slider structure, combined with a centralized lubrication system, allowing for continuous operation for many hours without maintenance. The crane achieves repeatable positioning accuracy through servo motor drive. The entire system, from unfolding to processing, offers a significant improvement in efficiency compared to traditional structures.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
