Description

Technical Field

[0001] This utility model relates to the field of machine tools, specifically to a saddle mounting structure for a turning and milling composite machine tool. Background Technology

[0002] To ensure rigidity, machine tools often use hardened rails. The hard friction between the saddle and the hardened rail relies entirely on guide rail oil to reduce frictional resistance. Over time, this can easily lead to gaps. In typical slant rail machine tools, the saddle is designed with an opposing structure, so the pressure is concentrated on the lower main rail, resulting in uneven stress. During long-term operation, the different friction forces lead to different degrees of wear, which is detrimental to later maintenance.

[0003] The existing saddle structure has one side that fits snugly against the guide rail, but the other side is difficult to fit snugly against the guide rail side due to structural issues, requiring the addition of a strip. Due to uneven force and different friction coefficients, the degree of wear varies over time. When adjusting the accuracy later, the workload increases significantly because the strip is difficult to remove, and the different wear levels also make it difficult to make corrections. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a saddle mounting structure for a turning-milling composite machine tool, thereby solving the technical problem of inconvenient precision adjustment between the saddle and the guide rail in previous turning-milling composite machine tools.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A saddle mounting structure for a milling and turning machine tool is provided, including:

[0007] The bed frame and the saddle, wherein the saddle slides on the guide rails of the bed frame;

[0008] The lower end of the saddle is provided with a front guide groove and a rear guide groove. The rear guide groove is provided with a first insert and a second insert, and the front guide groove is provided with a third insert.

The third insert is horizontally set and adapted to cooperate with the bottom surface of the front guide rail.

[0009] The first, second, and third inserts are all oblique blocks, with one side being a flat surface for contacting the guide rail and the other side being an oblique surface for engaging with the guide groove.

[0010] The first insert is provided with first adjusting bolts at both ends. The first adjusting bolts are threaded to the saddle. The bolt heads of the first adjusting bolts abut against the ends of the first insert. The two first adjusting bolts drive the first insert to move in the rear guide groove.

The bolt head of the third adjusting bolt abuts against the end of the third insert. The two third adjusting bolts drive the third insert to move in the front guide groove.

[0013] Furthermore, multiple horizontal oil grooves and one vertical oil groove are formed on the inclined surface of the inclined strip, and the vertical oil groove is connected to each of the horizontal oil grooves. Two oil inlet grooves are formed on the plane of the inclined strip, and an oil inlet hole is formed in the oil inlet groove, which is connected to the opposite vertical oil groove.

This is described in detail below.

[0034] like Figures 1 to 4 As shown, a saddle mounting structure for a milling and turning machine tool includes...

[0035] The bed 1 and the saddle 2 are slidably engaged with the guide rails on the bed 1.

[0036] The bed 1 is integrally cast with two rigid rails, a front guide rail 71 and a rear guide rail 72, and the saddle 2 slides with the two rigid rails.

[0037] Specifically, the lower end of the saddle 2 is provided with a front guide groove and a rear guide groove. The rear guide groove is provided with a first insert 31 and a second insert 32, and the front guide groove is provided with a third insert 33. The first insert 31 is horizontally set and adapted to cooperate with the bottom surface of the rear guide rail 72, the second insert 32 is vertically set and adapted to cooperate with the front side of the rear guide rail 72, and the third insert 33 is horizontally set and adapted to cooperate with the bottom surface of the front guide rail 71.

[0038] The first insert 31, the second insert 32 and the third insert 33 are all oblique strips, one side of which is a plane 3B for contacting the guide rail, and the other side of which is an oblique surface 3A for cooperating with the guide groove.

[0039] The first insert 31 is provided with first adjusting bolts 4 at both ends. The first adjusting bolts 4 are threaded to the saddle 2. The bolt heads of the first adjusting bolts 4 abut against the ends of the first insert 31. The two first adjusting bolts 4 drive the first insert 31 to move in the rear guide groove.

[0040] The second insert 32 is provided with a second adjusting bolt at each end. The second adjusting bolt is threaded to the saddle 2. The bolt head of the second adjusting bolt abuts against the end of the second insert 32. The two second adjusting bolts drive the second insert 32 to move in the rear guide groove.

[0041] The third insert 33 is provided with a third adjusting bolt at both ends. The third adjusting bolt is threaded to the saddle 2. The bolt head of the third adjusting bolt abuts against the end of the third insert 33. The two third adjusting bolts drive the third insert 33 to move in the front guide groove.

[0042] In this embodiment, the first insert 31 and the third insert 33 adjust the accuracy of the saddle 2 in the vertical direction, and the second insert 32 adjusts the accuracy of the saddle 2 in the front-back direction.

[0043] like Figure 2 and Figure 3 As shown, taking the adjustment of the first insert 31 as an example, when the first adjusting bolt 4 on one side pushes the first insert 31 to move, the first adjusting bolt 4 on the other side retracts accordingly, so that the first insert 31 has corresponding movement space.

[0044] Specifically, as an optional implementation method in this embodiment, such as Figure 4 As shown, taking the adjustment of the first insert 31 as an example, multiple horizontal oil grooves 61 and one vertical oil groove 62 are opened on the inclined surface 3A of the inclined strip block. The vertical oil groove 62 is connected to each of the horizontal oil grooves 61. Two oil inlet grooves are opened on the plane 3B of the inclined strip block. An oil inlet hole 63 is opened in the oil inlet groove. The oil inlet hole 63 is connected to the opposite vertical oil groove 62.

[0045] The oil inlet groove is located on the side of the entire oil inlet channel. Lubricating oil is transported through the oil inlet groove and the oil inlet hole 63 to the horizontal oil groove 61 and the vertical oil groove 62 on the side of the inclined plane 3A.

[0046] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the saddle 2 includes a saddle body 21, a rear buckle block 22 and a front buckle block 23. The lower end of the saddle body 21 is provided with a U-shaped groove and a right-angle groove. The rear buckle block 22 and the U-shaped groove form a rear guide groove, and the front buckle block 23 and the right-angle groove form a front guide groove.

[0047] The first insert 31 is disposed between the rear buckle block 22 and the rear guide rail 72, the second insert 32 is disposed in the U-shaped groove, and the third insert 33 is disposed between the front buckle block 23 and the front guide rail 71.

[0048] In this embodiment, the rear buckle block 22 and the front buckle block 23 are respectively fixed to the bottom of the saddle body 21 by bolts. The rear buckle block 22 and the front buckle block 23 are respectively provided with oil inlet channels, through which external lubricating oil is sent to the guide groove.

[0049] Specifically, as an optional implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, baffles 5 are provided at both ends of the saddle body 21, the rear buckle block 22, and the front buckle block 23. The baffles 5 are used to cover the adjusting bolts and prevent external impurities from entering the guide groove.

[0050] The present invention relates to a saddle mounting structure for a milling and turning machine tool. After the saddle 2 is installed on the bed 1, the debugging personnel can adjust the gap of the insert in the guide groove by controlling the adjusting bolts, thereby controlling the precise fit between the entire saddle 2 and the guide rail on the bed 1.
