Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and more specifically, to a multi-spindle CNC vertical machining center with simultaneous clamping of multiple workpieces. Background Technology

[0002] A gantry milling machine is an automated intelligent machining equipment developed from a general milling machine. A gantry milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually, the rotation of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, as well as various curved surfaces and boring holes.

[0003] Currently, metal cutting machine tools have basically achieved CNC program machining, including CNC vertical machining centers, machining centers, and CNC gantry milling machines. Among them, CNC gantry milling machines process a single workpiece with a single spindle, or process multiple workpieces sequentially. They cannot process multiple workpieces simultaneously, resulting in low production efficiency, high labor costs, and wasted manpower and energy. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-spindle CNC vertical machining center with simultaneous clamping of multiple workpieces. By cooperating with the main jaws and the auxiliary jaws, the clamping effect on the workpieces is improved. At the same time, multiple workpieces are clamped by the equally spaced main jaws and auxiliary jaws and processed by equally spaced machining tools, thereby greatly improving the production efficiency of workpieces and reducing production costs.

[0005] To achieve the above objectives, this utility model provides a multi-spindle CNC vertical machining center with simultaneous clamping of multiple workpieces, comprising a machine tool housing. A first moving module and a second moving module are respectively installed on the back and bottom of the machine tool housing. A feed mechanism and a clamping mechanism are respectively installed on the first and second moving modules. The feed mechanism includes: The housing is mounted on the mobile module one, and three sets of drive shafts are vertically rotatably connected at equal intervals inside the housing. The drive shafts extend to the bottom of the housing and are equipped with machining tools. The gear set is rotatably connected to the inner top of the housing, and a servo motor that drives the gear set to rotate is installed on the top of the housing, so that the gear set drives three sets of drive shafts to rotate. The clamping mechanism includes: A fixed base is installed on the second mobile module, and three sets of slide rails corresponding to the machining tools are symmetrically fixed on the top of the fixed base; The main gripper slides along the fixed base, and a secondary gripper is fixed on the main gripper. The main gripper has a through hole for the push mold to pass through, and the bottom end of the push mold extends into the interior of the fixed base. The gripper drive assembly is installed inside the fixed base and drives the push mold to reciprocate along the width direction of the fixed base.

[0006] Preferably, the gear set includes a drive gear connected to a servo motor and a first main shaft gear, a second main shaft gear, and a third main shaft gear connected to the top of three drive shafts. The first main shaft gear, the second main shaft gear, and the third main shaft gear mesh with each other through a first connecting gear and a third connecting gear, so that the first main shaft gear, the second main shaft gear, and the third main shaft gear rotate synchronously. The drive gear meshes with the second main shaft gear through the second connecting gear.

[0007] Preferably, the main gripper has a sliding groove on the fixed base at the bottom for the push mold to slide.

[0008] Preferably, a connecting plate is fixedly connected to the bottom end of the propulsion mold, and a propulsion plate is fixedly connected to the bottom surface of the connecting plate, and a hinge shaft is fixedly connected to the other end of the propulsion plate.

[0009] Preferably, a cylinder is installed inside the fixed base, and a second hinge shaft is connected to the output end of the cylinder, and a hinge rod is connected between the second hinge shaft and the first hinge shaft.

[0010] Preferably, threaded holes are provided at equal intervals on both sides of the main gripper.

[0011] The advantages of this utility model are as follows: First, during the movement of the hinge shaft two driven by the cylinder, the push plate is driven to move by the hinge rod, which simultaneously drives the connecting plate and the push mold to move. The push mold then drives the main jaw and the secondary jaw to move along the slide rail, thereby using the main jaw and the secondary jaw to clamp the workpiece. It is explained that when processing a T-shaped disc-shaped workpiece, the main jaw clamps the edge position with a large diameter and the secondary jaw clamps the edge position with a small diameter, thus improving the clamping effect on the workpiece. Secondly, the servo motor drives the drive gear to rotate, and the connecting gear two meshes with the main shaft gear two, thereby driving the drive gear to rotate. At the same time, due to the mutual meshing of the main shaft gear one, connecting gear one, main shaft gear two, connecting gear three, and main shaft gear three, the main shaft gear one and main shaft gear three rotate synchronously with the main shaft gear two, driving the drive shaft to rotate. Subsequently, the workpiece is drilled by the machining tool. Multiple workpieces are clamped by the equally spaced main jaws and secondary jaws, and multiple workpieces are processed by equally spaced machining tools, thereby greatly improving the production efficiency of workpieces and reducing production costs.

[0024] Example 1, see Figures 1 to 5As shown, this embodiment provides a multi-spindle CNC vertical machining center with simultaneous clamping of multiple workpieces, including a machine tool cover 100. A first moving module 200 and a second moving module 500 are respectively installed on the back and bottom of the machine tool cover 100. A feed mechanism 300 and a clamping mechanism 400 are respectively installed on the first moving module 200 and the second moving module 500. The feed mechanism 300 includes: The housing 302 is mounted on the mobile module 200, and three sets of drive shafts 310 are vertically rotatably connected at equal intervals inside the housing 302. The drive shafts 310 extend to the bottom end of the housing 302 and are equipped with machining tools 311. The gear set is rotatably connected to the inner top of the housing 302, and a servo motor 301 for driving the gear set to rotate is installed on the top of the housing 302, so that the gear set drives three sets of drive shafts 310 to rotate. The clamping mechanism 400 includes: The fixed base 404 is installed on the movable module 500, and three sets of slide rails 403 corresponding to the processing tool 311 are symmetrically fixed on the top of the fixed base 404. The main gripper 402 slides along the fixed base 404, and the secondary gripper 401 is fixed on the main gripper 402. The main gripper 402 has a through hole for the push mold 411 to pass through, and the bottom end of the push mold 411 extends into the interior of the fixed base 404. The gripper drive assembly is installed inside the fixed base 404 and drives the push mold 411 to reciprocate along the width direction of the fixed base 404.

[0025] like Figure 3As shown, in this embodiment, the gear set includes a drive gear 306 connected to the servo motor 301 and main shaft gears 303, 305, and 309 connected to the top ends of three drive shafts 310. The main shaft gears 303, 305, and 309 are meshed with each other via connecting gears 304 and 308, causing them to rotate synchronously. The drive gear 306 meshes with the main shaft gear 305 via connecting gear 307. The servo motor 301 drives the drive gear 306 to rotate, and the drive gear 306 is meshed with the spindle gear 305 through the connecting gear 307, thereby driving the drive gear 306 to rotate. At the same time, the spindle gear 303, the connecting gear 304, the spindle gear 305, the connecting gear 308, and the spindle gear 309 mesh with each other, so that the spindle gear 303 and the spindle gear 309 rotate synchronously with the spindle gear 305, and drive the drive shaft 310 to rotate. Then, the workpiece is drilled by the machining tool 311.

[0026] In this embodiment, a sliding groove 405 is provided on the fixed base 404 at the bottom of the main gripper 402, which allows the push mold 411 to slide. By sliding the push mold 411 inside the sliding groove 405, the main gripper 402 and the secondary gripper 401 are controlled to move, thereby clamping and releasing the workpiece.

[0027] like Figure 4 As shown, in this embodiment, a connecting plate 410 is fixedly connected to the bottom end of the push mold 411, and a push plate 409 is fixedly connected to the bottom surface of the connecting plate 410. A hinge shaft 406 is fixedly connected to the other end of the push plate 409. The push plate 409 is moved by the cylinder 407, which simultaneously moves the connecting plate 410 and the push mold 411. The push mold 411 then moves the main gripper 402 and the secondary gripper 401 along the slide rail 403, thereby using the main gripper 402 and the secondary gripper 401 to clamp the workpiece.

[0028] like Figure 5 As shown, in this embodiment, a cylinder 407 is installed inside the fixed base 404, and a second hinge shaft 408 is connected to the output end of the cylinder 407. A hinge rod 412 is connected between the second hinge shaft 408 and the first hinge shaft 406. During the process of the cylinder 407 driving the second hinge shaft 408 to move, the hinge rod 412 drives the push plate 409 to move, thereby achieving the effect of the main gripper 402 and the secondary gripper 401 clamping the workpiece.

[0029] In this embodiment, threaded holes 413 are provided at equal intervals on both sides of the main gripper 402. The position of the secondary gripper 401 on the main gripper 402 is adjusted by the corresponding engagement of the secondary gripper 401 with the threaded holes 413 via bolts.

[0030] In summary: Firstly, during the use of the equipment, the movement of the feeding mechanism 300 and the clamping mechanism 400 are controlled by the moving module 1 200 and the moving module 2 500 respectively. Then, as the cylinder 407 drives the hinge shaft 2 408 to move, the hinge rod 412 drives the push plate 409 to move, which in turn drives the connecting plate 410 and the push mold 411 to move. The push mold 411 then drives the main jaw 402 and the secondary jaw 401 to move along the slide rail 403, thereby using the main jaw 402 and the secondary jaw 401 to clamp the workpiece. It should be noted that when processing T-shaped disc-shaped workpieces, the main jaw 402 clamps the edge position with a large diameter, and the secondary jaw 401 clamps the edge position with a small diameter, thus improving the clamping effect of the workpiece. Subsequently, the servo motor 301 drives the drive gear 306 to rotate, and the connecting gear 307 meshes the spindle gear 305 and the drive gear 306, thereby driving the drive gear 306 to rotate. At the same time, the spindle gear 303, connecting gear 304, spindle gear 305, connecting gear 308, and spindle gear 309 mesh with each other, so that the spindle gear 303 and spindle gear 309 rotate synchronously with the spindle gear 305, driving the drive shaft 310 to rotate. Then, the machining tool 311 drills holes in the clamped workpiece. It should be noted that the existing CNC gantry milling generally uses a single spindle to process a single workpiece, or multiple workpieces are processed sequentially. However, in this utility model, multiple workpieces are clamped by the equally spaced main jaws 402 and secondary jaws 401, and multiple workpieces are processed by the equally spaced machining tools 311, thereby greatly improving the production efficiency of workpieces and reducing production costs.
