Description

Technical Field

[0001] This utility model belongs to the field of grinding technology and relates to a vertical multi-functional composite grinding machine. Background Technology

[0002] A grinding machine is a device that uses a high-speed rotating grinding head to grind workpieces, achieving precision grinding. For example, Chinese patent literature discloses a vertical grinding machine (application number: 201020220252.2), which consists of a base, a column, a slide, and an electric spindle. A worktable is mounted at one end of the base, and a column with a slide is located at the other end. A horizontal guide rail is provided on the slide, and a vertical guide rail is provided on the column. The column slides left and right along the horizontal guide rail on the slide.

[0003] The vertical grinding machine has the following shortcomings when in use: it can only load one grinding head at a time during grinding operations, which limits its function. For workpieces that need to grind both internal holes and external diameters, the machine needs to be stopped to change the grinding head when processing different parts of the workpiece, resulting in low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical multi-functional composite grinding machine. The technical problem this invention aims to solve is the low processing efficiency caused by the need to stop the machine to change grinding heads when processing different parts of a workpiece in existing vertical grinding machines.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A vertical multi-functional composite grinding machine includes a frame with a crossbeam. A horizontally rotatable workpiece positioning turntable is provided on the front side of the crossbeam. The workpiece positioning turntable is movable back and forth on the frame. Two horizontal slides are slidably connected to the crossbeam of the frame, and a vertical slide is slidably connected to each horizontal slide. An internal grinding head assembly is connected to one of the vertical slides, and a rotatable rotary table is connected to the other vertical slide. An external grinding head assembly is connected to the rotary table.

[0007] The two horizontal slides of this vertical multi-functional composite grinder can move the inner hole grinding head assembly and the outer cylindrical grinding head assembly left and right to be directly above the workpiece positioning turntable, respectively. The two vertical slides can move the inner hole grinding head assembly and the outer cylindrical grinding head assembly up and down, respectively. The workpiece positioning turntable can move the workpiece back and forth, so that the grinding of the inner hole and outer diameter can be completed in one clamping of the workpiece without stopping the machine to change the grinding head, resulting in high processing efficiency. At the same time, the rotary table can drive the outer cylindrical grinding head assembly to rotate synchronously relative to the vertical slides, so that the outer cylindrical grinding head assembly can grind the workpiece at multiple angles and directions, thereby realizing three-dimensional grinding of the workpiece and further improving processing efficiency.

[0008] In the aforementioned vertical multi-functional composite grinding machine, the crossbeam of the machine frame is provided with a first slide rail and two nut screw assemblies spaced vertically. Each nut screw assembly includes a screw rod and a nut seat screwed onto the screw rod. The first slide rail and the screw rod are both fixed to the machine frame in a left-right direction. Two horizontal slides are slidably arranged side-by-side on the first slide rail, and the two nut seats are respectively connected to the two horizontal slides. This allows for more precise movement of the two horizontal slides. Furthermore, the use of nut screw assemblies, where the nut seats are screwed onto the screw rod, allows for locking of the horizontal slides when not in motion, improving processing efficiency and quality. In addition to using nut screw assemblies, the two horizontal slides can also be driven by cylinders.

[0009] In the aforementioned vertical multi-functional composite grinding machine, the transverse slide has an arc-shaped locking portion, and the nut seat is cylindrical. The transverse slide is engaged with the nut seat through the locking portion, making the assembly and disassembly of the transverse slide and the nut seat more convenient.

[0010] In the above-mentioned vertical multi-functional composite grinding machine, there are three first slide rails. The upper, middle and lower parts of the horizontal slide plate are respectively connected to the three first slide rails by sliders. The first slide rails and the screws are arranged at intervals. The frame has recessed mounting grooves in the part located between the two first slide rails. The two nut screw assemblies are respectively arranged in the mounting grooves, and the screws of the two nut screw assemblies are parallel to each other and staggered vertically. By connecting the upper, middle, and lower parts of the horizontal slide plate to the three first slide rails via sliders, the movement of the horizontal slide plate becomes smoother and more stable. This allows for more precise positioning of the inner and outer grinding head assemblies mounted on the horizontal slide plate, improving processing efficiency and quality. Simultaneously, by arranging the first slide rails and the screw at intervals and by placing the two nut screw assemblies in mounting slots, the structure of this vertical multi-functional composite grinder becomes more compact. Furthermore, by setting the screws of the two nut screw assemblies parallel to each other and staggered vertically, the lengths of the screws in the two nut screw assemblies become more reasonable, reducing manufacturing costs.

[0011] In the aforementioned vertical multi-functional composite grinding machine, a second slide rail is fixedly mounted on the frame along the front-to-back direction. A slide block is slidably connected to the second slide rail. The workpiece positioning turntable is horizontally rotatable on the slide block. Grinding head magazines are respectively provided on the left and right sides of the workpiece positioning turntable. This allows the workpiece positioning turntable to not only rotate circumferentially but also move in the front-to-back direction, enabling the workpiece to be processed on the turntable to be simultaneously adjusted in position. Consequently, the internal grinding head assembly and the external grinding head assembly can better perform grinding operations on the workpiece, improving processing efficiency.

[0012] In the aforementioned vertical multi-functional composite grinding machine, the grinding head magazine includes a mounting base and a support turntable rotatably mounted on the mounting base. The support turntable has several elastic jaws arranged circumferentially along its edge, each jaw holding a spare internal grinding head and an external grinding head. The spare internal and external grinding heads in the magazine have different shank lengths, grinding wheel thicknesses, and outer diameters, allowing for on-demand use to meet the processing needs of different workpieces and improving processing efficiency.

[0013] Compared with existing technologies, the advantages of this vertical multi-functional compound grinding machine are as follows: the internal grinding head assembly and the external grinding head assembly of this vertical multi-functional compound grinding machine can move with the horizontal slide to the top of the workpiece positioning turntable, while the two vertical slides can drive the internal grinding head assembly and the external grinding head assembly to move up and down respectively, so that the grinding of the internal hole and the external circle can be completed in one clamping of the workpiece without stopping the machine to change the grinding head, resulting in high processing efficiency. At the same time, the turntable can drive the external grinding head assembly to rotate synchronously with respect to the vertical slides, so that the external grinding head assembly can perform grinding on the workpiece at multiple angles and directions, thereby realizing three-dimensional grinding of the workpiece and further improving processing efficiency.
