Abstract
Description
Technical Field
[0001] This utility model relates to an installation structure for a machining center, specifically an installation structure for a tool magazine bracket in a machining center. Background Technology
[0002] The tool magazine, a crucial component of a machining center, is mounted on a tool magazine bracket, which in turn is installed on the side of the machine tool column. Currently, tool magazines are typically installed by directly fixing the tool magazine bracket to the machine tool column with screws. Generally, only an adjustment mechanism is provided for adjusting the tool magazine's Y-axis position; all other directions are secured with screws, making it difficult to adjust the installation position and ensuring the horizontal and vertical alignment of the tool magazine bracket, thus affecting the tool magazine's installation accuracy. Furthermore, the Z-axis positioning of the tool magazine usually relies solely on the interaction between the keyway on the tool magazine bracket and the key block on the machine tool column. During transport or movement of the machine tool, key blocks are easily lost or the tool magazine may shift. To address this, an additional bracket is usually used for Z-axis positioning of the tool magazine during transport or movement, increasing costs while still failing to completely prevent tool magazine shifting. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a mounting structure for a tool magazine bracket in a machining center, which can ensure sufficient installation accuracy of the tool magazine bracket in the Z-axis and X-axis directions and realize the limiting of the tool magazine bracket in the Z-axis direction. The structure is simple, safe and reliable, has a long service life and low cost.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a mounting structure for a tool magazine bracket in a machining center, including several sets of limiting and clamping units and several sets of X-axis adjustment units. The tool magazine bracket is fixedly connected to the machine tool column by several screws. The tool magazine bracket is provided with several oblong holes, the long axis of each oblong hole is along the X-axis direction, and each screw passes through one oblong hole and is threadedly connected to the machine tool column. Several limiting bosses are provided on one side of the machine tool column, and the top of the tool magazine bracket is located below the several limiting bosses. A clamping device is provided between each limiting boss and the top of the tool magazine bracket. The limiting and clamping unit comprises a wedge block one and a wedge block two. The upper surface of the wedge block one is a plane one and the lower surface is an inclined plane one. The upper surface of the wedge block two is an inclined plane two and the lower surface is a plane two. The inclined plane one and the inclined plane two are fitted together. The plane one is fitted together with the bottom surface of a limiting boss. The plane two is fitted together with the top surface of the tool magazine bracket. The wedge block two is threaded to the machine tool column by a number of screws two. The number of X-axis adjustment units are respectively installed on the machine tool column. The number of X-axis adjustment units are used to adjust the installation position of the tool magazine bracket in the X-axis direction.
[0005] When installing the tool magazine bracket using the mounting structure of this utility model, the tool magazine bracket is initially installed on the machine tool column using several screws. With the screws not fully tightened, the tool magazine bracket's installation position in the X-axis direction is adjusted using several sets of X-axis adjustment units. Then, wedge blocks one and two are installed face-to-face using inclined planes one and two, and several screws are tightened to apply pressure to the tool magazine bracket in the Z-axis direction. Several limiting bosses restrict the tool magazine bracket's position in the Z-axis direction, ensuring the installation accuracy of the tool magazine bracket in the Z-axis direction and effectively preventing tool magazine displacement during transport or movement of the machine tool. Furthermore, the installation position of the tool magazine bracket in the X-axis direction can be adjusted using the several sets of X-axis adjustment units, ensuring the installation accuracy of the tool magazine bracket in the X-axis direction.
[0006] Preferably, the machine tool column has a vertical mounting surface and a horizontal mounting surface on one side, and the plurality of limiting bosses are disposed on the vertical mounting surface. The tool magazine bracket includes a vertical mounting plate and a horizontal mounting plate, and the horizontal mounting plate is supported by the horizontal mounting surface.
[0007] Preferably, a set of X-axis adjustment units is provided on both the vertical mounting surface and the horizontal mounting surface. The sides of the vertical and horizontal mounting plates furthest from the tool magazine are respectively positioned opposite one set of X-axis adjustment units. Each set of X-axis adjustment units includes an adjustment block, a tension screw, and a pressure screw. The adjustment block is fixedly connected to the machine tool column. The tension screw passes through the adjustment block and is threaded to one side of the tool magazine bracket. The pressure screw is threaded to the adjustment block, with its front end pressing against one side of the tool magazine bracket. When adjusting the installation position of the tool magazine bracket in the X-axis direction, tightening the tension screw applies tension in the X-axis direction to the tool magazine bracket; tightening the pressure screw applies pressure in the X-axis direction to the tool magazine bracket. By applying tension or pressure in the X-axis direction to the tool magazine bracket, the installation position of the tool magazine bracket in the X-axis direction can be adjusted.
[0008] Preferably, the tension screw and the pressure screw are respectively locked with lock nuts. After the tool magazine bracket is adjusted to the X-axis position, the lock nuts are tightened to prevent the tension screw and the pressure screw from loosening.
[0009] Preferably, the second wedge block has pre-drilled screw holes that extend through the width of the second wedge block, and the machine tool column has corresponding holes. When it is necessary to remove the first and second wedge blocks, after loosening several second screws, the first and second wedge blocks can be easily removed by screwing screws into the screw holes, thus enabling convenient disassembly of the tool magazine support.
[0010] Compared with the prior art, the present invention has the following advantages: The installation structure of the present invention realizes the quick installation and position adjustment of the tool magazine bracket through several sets of limiting and clamping units and several sets of X-axis adjustment units. The adjustment margin is large and the adjustment is convenient. It can ensure sufficient installation accuracy of the tool magazine bracket in the Z-axis and X-axis directions, and realize the limiting of the tool magazine bracket in the Z-axis direction. The structure is simple, safe and reliable, with long service life and low cost. Attached Figure Description

[0023] The mounting structure for the tool magazine bracket of the machining center in the embodiment is applied to... Figure 1 The tool magazine 5 with a robotic arm shown is designed to ensure that the center of the robotic arm is coaxial with the spindle by adjusting the installation accuracy of the tool magazine bracket 3. Figures 1-9As shown, the installation structure includes two sets of limiting and clamping units 1 and two sets of X-axis adjustment units 2. The tool magazine bracket 3 is fixedly connected to the machine tool column 4 by several screws 31. The tool magazine bracket 3 is provided with several oblong holes 32, the long axis of each oblong hole 32 is along the X-axis direction, and each screw 31 passes through an oblong hole 32 and is threadedly connected to the machine tool column 4. Two limiting bosses 41 are provided on one side of the machine tool column 4. The top of the tool magazine bracket 3 is located below the two limiting bosses 41. A set of limiting and clamping units 1 is clamped between each limiting boss 41 and the top of the tool magazine bracket 3. Each set of limiting and clamping units 1 includes a wedge block 11 and a wedge block 22. The upper surface of the wedge block 11 is flat. The upper surface of the wedge block 12 is inclined surface 14, the lower surface of the wedge block 12 is inclined surface 15, and the lower surface is flat surface 16. Inclined surface 14 and inclined surface 15 are in contact with each other. Flat surface 13 is in contact with the bottom surface of a limiting boss 41. Flat surface 16 is in contact with the top surface of the tool magazine support 3. The wedge block 12 is threaded to the machine tool column 4 by two screws 17. The wedge block 12 has a screw hole 18 that runs through the width of the wedge block 12. The machine tool column 4 has a hole that is opposite to the position of the screw hole 18. Two sets of X-axis adjustment units 2 are installed on the machine tool column 4 respectively. The two sets of X-axis adjustment units 2 are used to adjust the installation position of the tool magazine support 3 in the X-axis direction.
[0024] The machine tool column 4 has a vertical mounting surface 42 and a horizontal mounting surface 43 on one side. Two limiting bosses 41 are set on the vertical mounting surface 42. The tool magazine bracket 3 includes a vertical mounting plate 33 and a horizontal mounting plate 34, with the horizontal mounting plate 34 supported by the horizontal mounting surface 43. A set of X-axis adjustment units 2 are respectively provided on the vertical mounting surface 42 and the horizontal mounting surface 43. The side of the vertical mounting plate 33 and the horizontal mounting plate 34 away from the tool magazine 5 is respectively opposite to a set of X-axis adjustment units 2. Each set of X-axis adjustment units 2 includes an adjustment block 21, a tension screw 22, and a pressure screw 23. The adjustment block 21 is fixedly connected to the machine tool column 4. The tension screw 22 passes through the adjustment block 21 and is threaded to one side of the tool magazine bracket 3. The pressure screw 23 is threaded to the adjustment block 21.
