Description

Technical Field

[0001] This utility model relates to the field of gantry machine tool technology, and more specifically, to a deformation-resistant gantry machine tool crossbeam. Background Technology

[0002] Gantry milling machines, also known as gantry machining centers, are key pieces of equipment widely used for machining large and heavy parts. The core structure of a gantry milling machine consists of two side columns, a top connecting beam, and a crossbeam that can move up and down along the columns. The crossbeam is a crucial load-bearing and motion-based component of the spindle system, and its structural performance directly determines the machining accuracy and service life of the machine tool. Because the spindle head has a certain weight, its positional changes as it moves along the crossbeam guide rails generate varying bending moments on the crossbeam, causing it to bend and deform. The deformation is usually most severe when the spindle head moves to the middle of the crossbeam. This deformation directly affects positioning accuracy. Therefore, we have made improvements and proposed a deformation-resistant gantry milling machine crossbeam. Utility Model Content

[0003] The main purpose of this utility model is to provide a deformation-resistant gantry milling machine beam, which can effectively solve the problem that when the spindle box moves on the guide rail, its position change will generate a changing bending moment on the beam, causing the beam to bend and deform. When the spindle box moves to the middle of the beam, the deformation is usually the most serious, and the deformation of the beam will directly affect the positioning accuracy.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A deformation-resistant gantry milling machine crossbeam includes a crossbeam body, with baffles movably installed at both ends of the crossbeam body, a cover plate movably installed on the upper side of the crossbeam body, an internal groove provided inside the crossbeam body, two fixing plates installed in the middle of the bottom inner wall of the internal groove, and a support mechanism provided on one side of the fixing plates and baffles.

[0006] Preferably, positioning grooves are provided on the inner walls of both ends of the built-in groove, and positioning strips that slide in cooperation with the positioning grooves are installed on the surfaces of both ends of the baffle.

[0007] Preferably, the support mechanism includes a first mounting bracket and a second mounting bracket, wherein two first mounting brackets are provided and are respectively installed on one side of each baffle, and two second mounting brackets are provided and are respectively installed on one side of each fixed plate.

[0008] Preferably, each of the first and second mounting brackets has a number of reinforcing ribs installed inside.

[0009] Preferably, each of the two sides of the top of the first mounting bracket is equipped with a guide slider, and the inner walls of the two sides of the built-in groove are equipped with slide rails that slide in cooperation with the guide slider.

[0010] Preferably, the upper surface of the crossbeam body is equipped with a number of first fixing bolts for fixing the top of the first mounting frame, and each baffle is equipped with a number of second fixing bolts for fixing one end of the first mounting frame on one side surface.

[0011] Preferably, each of the fixing plates has a plurality of third fixing bolts installed on one side surface for fixing one end of the second mounting bracket.

[0012] Preferably, each of the first mounting brackets has a first threaded hole on its upper surface and one end surface that mates with the first fixing bolt and the second fixing bolt, and each of the second mounting brackets has a second threaded hole on one end surface that mates with the third fixing bolt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Both the first and second mounting brackets are equipped with several sets of reinforcing ribs, which enhance the overall strength of the crossbeam body, making it more stable and less prone to deformation. The reinforcing ribs located inside the first mounting brackets on both sides reduce the deformation of the crossbeam body during its ascent, while the reinforcing ribs located inside the second mounting bracket in the middle reduce the deformation of the middle part of the crossbeam body during the movement of the spindle box. The first, second, and third fixing bolts, along with the corresponding first and second threaded holes, can fix the first and second mounting brackets in their positions within the built-in grooves. This makes installation, disassembly, and replacement convenient. Attached Figure Description

[0024] like Figure 6 As shown, positioning grooves 401 are provided on the inner walls of both ends of the built-in groove 4, and positioning strips 201 that slide in cooperation with the positioning grooves 401 are installed on both ends of the baffle 2. Through the sliding cooperation between the positioning strips 201 and the positioning grooves 401, the baffle 2 can be positioned to prevent its installation position from shifting.

[0025] like Figures 3 to 6As shown, the support mechanism 6 includes a first mounting bracket 601 and a second mounting bracket 602. Two first mounting brackets 601 are provided and installed on one side of each baffle 2. Two second mounting brackets 602 are provided and installed on one side of each fixed plate 5. Each first mounting bracket 601 and each second mounting bracket 602 has several reinforcing ribs 603 installed inside. Guide sliders 604 are installed on the top of both sides of each first mounting bracket 601. Slide rails 402 that slide and engage with the guide sliders 604 are installed on the inner walls of both sides of the built-in groove 4. Several mounting brackets 602 for supporting the first mounting brackets 601 are installed on the upper surface of the crossbeam body 1. The first fixing bolt 101 is used to fix the top. Several second fixing bolts 202 are installed on one side surface of each baffle 2 for fixing one end of the first mounting bracket 601. Several third fixing bolts 501 are installed on one side surface of each fixing plate 5 for fixing one end of the second mounting bracket 602. The upper surface and one end surface of each first mounting bracket 601 are provided with first threaded holes 605 that cooperate with the first fixing bolt 101 and the second fixing bolt 202. The one end surface of each second mounting bracket 602 is provided with second threaded holes 606 that cooperate with the third fixing bolt 501.

[0026] The first mounting bracket 601 and the second mounting bracket 602 can be fixed in the position inside the built-in groove 4 by the cooperation between the first fixing bolt 101, the second fixing bolt 202 and the third fixing bolt 501 and the first threaded hole 605 and the second threaded hole 606 at the corresponding positions. The installation and disassembly operations are convenient and the replacement is easy.

[0027] The working principle of this type of deformation-resistant gantry milling machine beam:

[0028] The first mounting bracket 601 is installed to both sides of the inner cavity 4 through the sliding engagement between the guide slider 604 and the slide rail 402. The top of the first mounting bracket 601 is fixed by the first fixing bolt 101. The baffle 2 can be installed to both ends of the crossbeam body 1 through the sliding engagement between the positioning strip 201 and the positioning slide groove 401. One end of the first mounting bracket 601 is fixed by the second fixing bolt 202. The second mounting bracket 602 is installed to one side of each fixing plate 5. The positions of the two second mounting brackets 602 are then adjusted by the third fixing bolt 501. After fixing the cover plate 3, the installation of the support mechanism 6 inside the crossbeam body 1 can be completed. Several sets of reinforcing ribs 603 are provided inside the first mounting frame 601 and the second mounting frame 602, which can enhance the overall strength of the crossbeam body 1, making the crossbeam body 1 more stable and less prone to deformation. The reinforcing ribs 603 inside the first mounting frames 601 on both sides can reduce the deformation generated during the rise of the crossbeam body 1, and the reinforcing ribs 603 inside the second mounting frame 602 in the middle can reduce the deformation generated in the middle of the crossbeam body 1 during the movement of the spindle box.
