A gantry milling machine beam compensation mechanism

Abstract

This utility model relates to the field of gantry milling machine technology, specifically a gantry milling machine crossbeam compensation mechanism, including a beam end compensation component and a crossbeam component mounted on the beam end compensation component. The beam end compensation component includes a load-bearing base, two symmetrically distributed sensors mounted on the top of the load-bearing base, two top support plates fixedly mounted on the beam frame, a chassis fixedly mounted on the sensors, and a motor mounted inside the chassis. By adding beam end compensation components with a slight inclination angle to both ends of the crossbeam in an existing gantry milling machine, when the milling head slides relative to the outside of the crossbeam and performs finishing on the metal material, the milling head under reverse pressure will exert pressure on the crossbeam. Once the pressure at both ends of the crossbeam is too large and deformation occurs, it will interfere with the machining accuracy of the milling head. The compensation components added to both ends of the crossbeam can buffer the reverse pressure of the milling head while ensuring the smooth operation of the milling head during operation.

Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine technology, specifically a gantry milling machine crossbeam compensation mechanism. Background Technology

[0002] A gantry milling machine is a milling machine with a gantry frame and a horizontal long bed. Multiple milling cutters can be used simultaneously to machine surfaces on a gantry milling machine, resulting in high machining accuracy and production efficiency. It is suitable for machining large workpieces on planes and inclined surfaces in batch and mass production. The milling machine's crossbeam compensation mechanism is mainly used to solve the tilting problem caused by gravity, deformation, or vibration during the movement of the crossbeam, thereby improving machining accuracy.

[0003] Because the crossbeam is equipped with a milling and boring head for boring and milling operations, as the milling and boring head comes into contact with the metal material and is subjected to reverse pressure, the pressure on the milling and boring head will act on the crossbeam. Once there is a slight change in the tilt angle at the end of the crossbeam, the accuracy of the milling and boring head will change.

[0004] In view of this, a gantry milling machine beam compensation mechanism was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A gantry milling machine crossbeam compensation mechanism includes a beam end compensation component and a crossbeam assembly mounted on the beam end compensation component. The beam end compensation component includes a load-bearing base, two sensors symmetrically distributed on the top of the load-bearing base, two top support plates fixedly mounted on the beam frame, a housing fixedly mounted on the sensors, a motor mounted inside the housing, a lead screw connected to the motor, a booster end movably mounted on the threaded section of the lead screw, a shaft movably mounted on the top of the booster end, two traction plates mounted on both ends of the shaft, and a sliding column mounted on the other end of the traction plates. The crossbeam assembly includes a beam frame movably mounted outside the sliding column and placed horizontally, and two plugs mounted on both ends of the beam frame.

[0008] In a preferred embodiment, the present invention can be further configured as follows: four symmetrically distributed calibration grooves are provided on the inner walls at both ends of the beam frame, and two symmetrically distributed second reinforcing springs and a limiting pad fixedly installed on the second reinforcing springs facing the sliding column are provided inside the calibration grooves;

[0009] The end of the limiting pad away from the second reinforcing spring has an arc-shaped groove.

[0010] In a preferred embodiment, the present invention can be further configured such that: two insertion rods are fixedly installed at the bottom of the plug, and the two insertion rods are adapted to pass through two of the calibration grooves.

[0011] In a preferred embodiment, the present invention can be further configured such that the detection end of the sensor is adapted to fit against the bottom of the beam frame, and the sensor is connected to the motor via a wire.

[0012] In a preferred embodiment, the present invention can be further configured such that: four symmetrically distributed supports are fixedly installed on the top of both ends of the load-bearing base, and the top support plate is welded to two of the supports.

[0013] In a preferred embodiment, the present invention can be further configured such that: a slide is provided on the top of the top support plate, and a clamping plate and a first reinforcing spring are installed on the top support plate, and the shaft is adapted to pass through the slide, and the top end of the booster head passes through the slide.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. This utility model adds beam end compensation components with a slight inclination angle to both ends of the crossbeam of the existing gantry milling machine. When the milling boring head slides relative to the outside of the crossbeam and performs precision machining on the metal material, the milling boring head under reverse pressure will exert pressure on the crossbeam. Once the pressure on both ends of the crossbeam is too large and deformation occurs, it will interfere with the machining accuracy of the milling boring head. The compensation components added to both ends of the crossbeam can buffer the reverse pressure of the milling boring head while ensuring the smooth operation of the milling boring head.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a gantry milling machine beam compensation mechanism.

[0025] Example 1:

[0026] Combination Figures 1 to 3 As shown, the present invention provides a gantry milling machine crossbeam compensation mechanism, including a beam end compensation component 100 and a crossbeam assembly 200 mounted on the beam end compensation component 100. The beam end compensation component 100 is used to provide calibration compensation and protection for the tilt angle provided by the crossbeam assembly 200.

[0027] The beam end compensation assembly 100 includes a load-bearing base 110, two sensors 120 mounted on the top of the load-bearing base 110 and symmetrically distributed, two top support plates 160 fixedly mounted on the beam frame 210, a housing 130 fixedly mounted on the sensors 120, a motor 140 mounted inside the housing 130, a lead screw 1401 connected to the motor 140, a booster end 150 movably mounted on the threaded section of the lead screw 1401, a shaft 170 movably mounted on the top of the booster end 150, two traction plates 1701 mounted on both ends of the shaft 170, and a sliding column 1702 mounted on the other end of the traction plate 1701.

[0028] The beam assembly 200 includes a beam frame 210 that is movably mounted outside the slide column 1702 and is horizontally positioned, and two plugs 220 that are mounted at both ends of the beam frame 210;

[0029] The inner walls at both ends of the beam frame 210 are provided with four symmetrically distributed calibration grooves 2101. The calibration grooves 2101 are provided with two symmetrically distributed second reinforcing springs 230 and a limiting pad 240 fixedly installed on the second reinforcing springs 230 facing the slide column 1702.

[0030] The end of the limiting pad 240 away from the second reinforcing spring 230 has an arc-shaped groove;

[0031] The bottom of the plug 220 is fixedly installed with two insertion rods, and the two insertion rods are adapted to pass through two calibration grooves 2101.

[0032] Preferably, the two sliding columns 1702 are fixedly installed on the top of the two traction plates 1701, and in the initial state, the traction plates 1701 and the top support plate 160 form a triangular structure, while the bottom end of the first reinforcing spring 1602 is welded to the top support plate 160 to provide stabilization protection for the beam frame 210 in the initial state.

[0033] Specifically, when the milling head moves laterally along the outside of the beam frame 210 and transfers the reaction force on the metal material, the beam frame 210, which is under pressure, will apply pressure to the sensor 120. Finally, after the sensor 120 detects the tilting trend of the end of the beam frame 210, it will actively cause the traction plate 1701 and the sliding column 1702 to calibrate and lift it.

[0034] Example 2:

[0035] Combination Figure 2 and Figure 3 As shown, based on Embodiment 1, the detection end of the top of the sensor 120 is adapted to fit the bottom of the beam frame 210, and the sensor 120 is connected to the motor 140 through a wire.

[0036] Four symmetrically distributed supports are fixedly installed on the top of both ends of the load-bearing base 110, and the top support plate 160 is welded to two of the supports.

[0037] The top of the top support plate 160 is provided with a slide rail, and a clamping plate 1601 and a first reinforcing spring 1602 are installed on the top support plate 160. The shaft 170 is adapted to pass through the slide rail, and the top end of the booster end 150 passes through the slide rail.

[0038] Preferably, the two sensors 120 are connected to an external power supply via wires and detect minute changes in the inclination angle at both ends of the beam 210 via the cloud.

[0039] When the sensor 120 issues a command and starts the motor 140, the lead screw 1401 driven by the motor 140 will push the push end 150 to extend back and forth, thereby calibrating and compensating for the slight changes in the tilt angle at both ends of the beam frame 210.

[0040] The working principle and usage process of this utility model: When the machine tool moving part or driving part moves laterally along the outside of the beam frame 210, once the end of the beam frame 210 is subjected to excessive pressure and causes a slight change in the tilt angle of the moving part or driving part, the motor 140 will be started the instant the sensor 120 detects the pressure. After the motor 140 runs, it will work with the lead screw 1401 to push the push end 150 to slide effectively. Finally, the push end 150 will drive the shaft 170, the two traction plates 1701 and the two sliding columns 1702 to extend, and the end of the beam frame 210 that is subjected to excessive pressure and has a slight change in tilt angle can be compensated and calibrated.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
