Description

Technical Field

[0001] This utility model relates to the field of machining center technology, specifically to a spindle box device and a machining center machine tool. Background Technology

[0002] The existing spindle box assembly of a machining center includes a slide, a spindle box mounted on the slide, a lead screw mechanism, and two counterweight mechanisms. The lead screw mechanism is located at the rear end of the spindle box, and the two counterweight mechanisms are installed on the left and right sides of the lead screw mechanism. This structure makes the machine head prone to tilting backward, which affects the machining accuracy and service life of the machine tool. In addition, the lead screw mechanism bears a large weight and pressure during operation, which makes it prone to wear and affects its service life. Furthermore, the distance between the center of the spindle box and the front end face of the column is relatively large, resulting in insufficient rigidity of the spindle box. Utility Model Content

[0003] The present invention aims to provide a spindle box device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a spindle box device, including a slide and a spindle box, a lead screw mechanism and a counterweight mechanism mounted on the slide. The lead screw mechanism and the counterweight mechanism are respectively arranged on the left and right sides of the spindle box and are drivenly connected to the spindle box. The lead screw mechanism and the counterweight mechanism cooperate with each other to drive the spindle box to slide up and down.

[0005] Preferably, the lead screw mechanism and the counterweight mechanism are symmetrically arranged on the left and right sides of the spindle box, and the center lines of the lead screw mechanism and the counterweight mechanism are symmetrical with respect to the center line of the spindle box.

[0006] Preferably, the lead screw mechanism includes a motor, a lead screw, and a sliding sleeve. The motor is driven by the lead screw, the sliding sleeve is slidably mounted on the lead screw, and the sliding sleeve is fixedly connected to one side of the spindle box.

[0007] Preferably, the counterweight mechanism is a counterweight balance cylinder.

[0008] Preferably, the front side of the slide has a U-shaped mounting groove with an opening facing forward and extending vertically, and the spindle box is installed in the U-shaped mounting groove.

[0009] Preferably, guide rails are installed at the front and rear ends of the left and right sides of the spindle box, and sliders that cooperate with the guide rails are fixedly installed on the groove wall of the U-shaped mounting groove.

[0010] This utility model also provides a machining center, including the spindle box device described above.

[0011] Preferably, it also includes a column, a base, a saddle, and a worktable. The spindle box is slidably mounted on the column, the column is fixedly mounted on the base, and the worktable is slidably mounted on the base via the saddle.

[0012] This utility model has the following beneficial effects:

[0013] (1) The head of the machining center is less likely to tilt backward, thereby improving the machining accuracy and service life of the machine tool.

[0014] (2) The lead screw mechanism and the counterweight mechanism are symmetrically arranged on the left and right sides of the spindle box. The lead screw mechanism and the counterweight mechanism drive the spindle box to slide up and down simultaneously on the left and right sides, which reduces the weight and pressure borne by the lead screw mechanism during the movement, making the lead screw mechanism less prone to wear and extending its service life.

[0015] (3) The screw mechanism is installed on the left side of the spindle box, which frees up the space for the original rear end of the spindle box to install the screw mechanism. This allows the spindle box to be installed closer to the slide, making the center of the spindle box closer to the front end of the column, thus effectively improving the rigidity of the spindle box.

[0025] See Figure 1-5 As shown in the figure, as an embodiment of this utility model, a spindle box device is provided, specifically a spindle box device for a machining center, including a slide 2 and a spindle box 1, a lead screw mechanism 3, and a counterweight mechanism 4 mounted on the slide 2. The lead screw mechanism 3 and the counterweight mechanism 4 are respectively arranged on the left and right sides of the spindle box 1 and are drivenly connected to the spindle box 1. The lead screw mechanism 3 and the counterweight mechanism 4 cooperate with each other to drive the spindle box 1 to slide up and down. Specifically, the lead screw mechanism 3 and the counterweight mechanism 4 are symmetrically arranged on the left and right sides of the spindle box 1, and the center lines of the lead screw mechanism 3 and the counterweight mechanism 4 are symmetrical with respect to the center line of the spindle box 1. This technical solution has the following advantages:

[0026] (1) The head of the machining center is less likely to tilt backward, thereby improving the machining accuracy and service life of the machine tool.

[0027] (2) The lead screw mechanism 3 and the counterweight mechanism 4 are symmetrically arranged on the left and right sides of the spindle box 1. The lead screw mechanism 3 and the counterweight mechanism 4 drive the spindle box 1 to slide up and down simultaneously on the left and right sides, which reduces the weight and pressure borne by the lead screw mechanism 3 during the movement, making the lead screw mechanism 3 less prone to wear and extending its service life.

[0028] (3) The lead screw mechanism 3 is installed on the left side of the spindle box 1, which frees up the space where the lead screw mechanism 3 was originally installed at the rear end of the spindle box 1. This allows the installation position of the spindle box 1 to be moved further back to the interior of the slide block 2, making the center of the spindle box 1 closer to the front end of the column 8, thereby effectively improving the rigidity of the spindle box 1.

[0029] In this embodiment, the lead screw mechanism 3 includes a motor 31, a lead screw 32 and a sliding sleeve 33. The motor 31 is driven to the lead screw 32. The sliding sleeve 33 is slidably disposed on the lead screw 32 and is fixedly connected to one side of the spindle box 1. The counterweight mechanism 4 is a counterweight balance cylinder.

[0030] In this embodiment, the front side of the slide block 2 is provided with a U-shaped mounting groove 5 that faces forward and runs vertically through the slide block. The spindle box 1 is installed in the U-shaped mounting groove 5. The front and rear ends of the left and right sides of the spindle box 1 are respectively equipped with guide rails 6. The wall of the U-shaped mounting groove 5 is fixedly installed with a slider 7 that cooperates with the guide rails 6 to ensure the smoothness and stability of the spindle box 1 sliding up and down.

[0031] This utility model also provides a machining center, including the spindle box device, column 8, saddle, base, and worktable described in the above embodiments. The column 8 is fixedly mounted on the base, the spindle box device is slidably mounted on the column 8, and the worktable is slidably mounted on the base via the saddle. The spindle box device is located above the worktable. This machining center has the following advantages:

[0032] (1) The head of the machining center is less likely to tilt backward, thereby improving the machining accuracy and service life of the machine tool.

[0033] (2) The lead screw mechanism 3 and the counterweight mechanism 4 are symmetrically arranged on the left and right sides of the spindle box 1. The lead screw mechanism 3 and the counterweight mechanism 4 drive the spindle box 1 to slide up and down simultaneously on the left and right sides, which reduces the weight and pressure borne by the lead screw mechanism 3 during the movement, making the lead screw mechanism 3 less prone to wear and extending its service life.

[0034] (3) The lead screw mechanism 3 is installed on the left side of the spindle box 1, which frees up the space where the lead screw mechanism 3 was originally installed at the rear end of the spindle box 1. This allows the installation position of the spindle box 1 to be moved further back to the interior of the slide block 2, making the center of the spindle box 1 closer to the front end of the column 8, thereby effectively improving the rigidity of the spindle box 1.
