Abstract
Description
Technical Field
[0001] This application relates to the field of machine tools, and more particularly to a fixed support for transporting machine tools. Background Technology
[0002] Machine tools, as a type of high-precision processing equipment, play a crucial role in many fields such as machinery manufacturing, automotive industry, and aerospace. After production is completed, machine tools need to be transported to the factory for setup.
[0003] refer to Figure 1 The machine tool 5 includes a bed 51, a worktable 52, a spindle unit 53, and a ball screw 54. The worktable 52 is mounted on the bed 51 and is used to support and fix the workpiece. The spindle unit 53 is used to mount the cutting tool and drive the cutting tool to rotate at high speed. The spindle unit 53 is vertically slidably connected to the bed 51 through the ball screw. The spindle unit 53 is only connected to the bed 51 through the ball screw.
[0004] During machine tool transportation, bumps on the road can cause relative displacement between the spindle unit and the ball screw. Since the ball screw needs to achieve high-precision positioning of the spindle, any collision with the ball screw will lead to a reduction in the spindle's accuracy. Utility Model Content
[0005] In order to reduce the displacement of the spindle unit relative to the ball screw during bumpy road transportation, thereby reducing the impact of the ball screw during transportation, this application provides a fixed bracket for machine tool transportation.
[0006] This application provides a fixed bracket for transporting machine tools, which adopts the following technical solution:
[0007] A fixed bracket for transporting machine tools includes a horizontal bar and two support rods. One end of each support rod is mounted on the horizontal bar, and the other end of each support rod abuts against the machine bed. The horizontal bar is connected to the lower end face of the spindle unit.
[0008] By adopting the above technical solution, the support rod is connected to the machine tool bed, and the horizontal bar is connected to the spindle unit. The distance from the end of the support rod away from the horizontal bar to the horizontal bar remains unchanged. This ensures that the spindle unit is supported by the support rod and the horizontal bar during the road transportation of the lathe, thus ensuring that the distance between the spindle unit and the machine tool bed remains unchanged, reducing the relative movement between the ball screw and the spindle unit, and reducing the occurrence of collisions between the ball screw and the machine tool bed.
[0009] Optionally, the two support rods are distributed along the length of the horizontal rod, and the distance between the support rods gradually decreases in the vertically upward direction.
[0010] By adopting the above technical solution, the distance between the two support rods gradually decreases in the vertical direction, that is, the support rods are set at an inclination, thereby providing shear torque to the horizontal rod, dispersing the shear stress on the horizontal rod, reducing the bending deformation of the horizontal rod, and improving the stability of the horizontal rod.
[0011] Optionally, a first reinforcing rib is provided between the support rod and the horizontal rod.
[0012] By adopting the above technical solution, the first reinforcing rib further improves the connection strength between the support rod and the horizontal rod.
[0013] Optionally, the end of the support rod facing away from the horizontal bar is provided with a contact piece to increase the contact area with the bed.
[0014] By adopting the above technical solution, the contact piece increases the contact area between the support rod and the bed, reduces the pressure of the support rod on the bed, and thus reduces the deformation of the bed during transportation.
[0015] Optionally, a second reinforcing rib is provided between the contact piece and the support rod.
[0016] By adopting the above technical solution, the second reinforcing rib further improves the connection strength between the support rod and the contact piece.
[0017] Optionally, the horizontal bar includes a first bar and a second bar, and two support bars are respectively disposed on the first bar and the second bar. Both the first bar and the second bar are provided with abutment pieces, which abut against each other and are connected by bolts.
[0018] By adopting the above technical solution, the horizontal bar is divided into a first bar and a second bar, and two support bars are respectively set on the first bar and the second bar, realizing the separate setting of the fixed bracket. The fixed bracket is more flexible in disassembly and assembly, and it is easier to put the fixed bracket into the machine tool, which improves the rationality of the fixed bracket. The abutment plate is connected by bolts to connect the first bar and the second bar. The structure is simple and easy to operate.
[0019] Optionally, an auxiliary bracket is provided on the horizontal bar, the length direction of the auxiliary bracket is perpendicular to the length direction of the horizontal bar, and the end of the auxiliary bracket away from the horizontal bar is used to connect to the bed.
[0020] By adopting the above technical solution, the auxiliary support is perpendicular to the length direction of the horizontal bar. The auxiliary support is used to resist vibrations perpendicular to the length direction of the horizontal bar, thereby better reducing the vibration of the main shaft unit during road transportation.
[0021] Optionally, the auxiliary support is provided with a connector, which includes a connecting bolt and a connecting piece. The connecting piece has a waist-shaped hole extending in the vertical direction, and the connecting bolt passes through the waist-shaped hole and is threaded onto the horizontal bar.
[0022] By adopting the above technical solution, the auxiliary bracket can be connected to the horizontal bar through the slotted hole and the connecting piece. The slotted hole is used to adjust the height between the auxiliary bracket and the horizontal bar, thereby better adapting to different spindle models and improving the applicability of the fixed bracket.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The horizontal bar is used to connect with the lower end face of the spindle, and the support bar is used to abut against the bed, reducing the change in distance between the spindle unit and the bed during road transportation, thereby reducing the relative movement between the spindle unit and the ball screw diameter, and reducing the collision of the ball screw;
[0025] 2. The horizontal bar includes a first bar and a second bar, enabling flexible disassembly of the fixed bracket;
[0026] 3. The auxiliary support further improves the support effect of the horizontal bar on the spindle unit. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 2 -Appendix Figure 4 This application will be described in further detail.
[0033] This application discloses a fixed bracket for transporting machine tools. (Refer to...) Figure 2 and Figure 3 A fixed support for transporting machine tools includes a horizontal rod 1, two support rods 2, and an auxiliary support 3. The horizontal rod 1 includes a first rod 11 and a second rod 12, both of which are horizontally arranged and on the same straight line. Abutment pieces 13 are provided on the end of the first rod 11 facing the second rod 12 and the end of the second rod 12 facing the first rod 11. The two abutment pieces 13 abut against each other and are connected by bolts. The first rod 11 and the second rod 12 abut against the lower end face of the spindle unit 53.
[0034] Reference Figure 2 and Figure 3 Two support rods 2 correspond to the first rod 11 and the second rod 12 respectively. One end of each support rod 2 is fixedly set on the lower end face of the first rod 11 and the second rod 12 respectively. The distance between the two support rods 2 gradually decreases in the vertical upward direction. A first reinforcing rib 4 is provided between each support rod 2 and the first rod 11 and the second rod 12. A contact piece 21 is provided at the end of the support rod 2 away from the main spindle unit 53. The area of the contact piece 21 is larger than the cross-sectional area of the support rod 2. The contact piece 21 is used to abut against the bed 51. A second reinforcing rib 22 is fixedly set between the contact piece 21 and the support rod 2.
[0035] Reference Figure 2 and Figure 4 The auxiliary support 3 includes a horizontal auxiliary rod 31 and a vertical auxiliary rod 32. The horizontal auxiliary rod 31 is horizontal and perpendicular to the length direction of the first rod 11. A connector 33 is provided on the horizontal auxiliary rod 31. The connector 33 includes a connecting piece 331 and two connecting bolts 332. The connecting piece 331 is fixedly set on one end of the horizontal auxiliary rod 31. Two oblong holes 333 are opened on the connecting piece 331. The oblong holes 333 extend in the vertical direction. The two connecting bolts 332 correspond to the two oblong holes 333. The tail of the connecting bolt 332 passes through the oblong holes 333 and is threaded to the first rod 11. The vertical auxiliary rod 32 is fixedly connected to the end of the horizontal auxiliary rod 31 away from the first rod 11. The lower end face of the vertical auxiliary rod 32 is fixedly connected to the bed 51 by bolts.
[0036] The implementation principle of a fixed bracket for machine tool transportation in this application embodiment is as follows: When the machine tool 5 completes production and needs to be transported to the required location by guide wheels, the operator can first put the first rod 11 and the second rod 12 with support rod 2 into the machine tool 5. The first rod 11 and the second rod 12 are connected to the abutment piece 13 by bolts, so that the first rod 11 and the second rod 12 are in a straight line, and the support rod 2 abuts against the bed 51.
[0037] Next, the auxiliary horizontal bar 1 is connected to the first bar 11 via connecting bolts 332 and connecting piece 331, and the vertical auxiliary bar 32 is connected to the bed 51. Then, the position of the spindle unit 53 is adjusted so that the spindle unit 53 abuts against the first bar 11 and the second bar 12, thereby reducing the change in distance between the spindle unit 53 and the bed 51 during transportation.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
