Description

Technical Field

[0001] This utility model relates to the field of machining equipment, specifically a support structure for a machine tool magazine. Background Technology

[0002] Rotary tool magazines are commonly used automatic tool changers in machining centers. A tool magazine system provides the necessary tool storage and changing capabilities for automated machining processes. Its automatic tool changing mechanism and the ability to store multiple tools have revolutionized traditional, human-intensive production methods. Controlled by computer programs, various machining operations such as milling, drilling, boring, and tapping can be performed, significantly shortening machining time and reducing production costs—this is the most significant characteristic of a tool magazine system.

[0003] Existing machine tool magazine support structures are generally integrated into the rotary structure. If one part malfunctions, the entire structure must be disassembled for maintenance, which is inconvenient. Furthermore, the scissor-type clamping structure, typically used to hold the tool, is not stable enough when securing the tool, posing a risk of wobbling. Therefore, those skilled in the art have provided a support structure for machine tool magazines to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a support structure for a machine tool magazine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A support structure for a machine tool magazine includes a first bracket, a support plate, and a clamping module. Six square notches are evenly distributed along the edge of the support plate. A clamping module is bolted to the bottom of each square notch. The clamping module has a triangular structure. A pair of arc-shaped clamping blocks are slidably connected to the center of the clamping module. Sliding through holes are symmetrically arranged on the side of the middle portion of the clamping module. Two guide rods are symmetrically arranged on the back of each arc-shaped clamping block. The guide rods are slidably connected to the sliding through holes. A transmission rod is arranged between the two guide rods. A wear-resistant wire harness is fixedly connected to the tail of the transmission rod. The transmission rod is slidably connected to the clamping module. A spring mounting hole is provided between the two sliding through holes. A spring is installed in the spring mounting hole and fits against the back of the arc-shaped clamping plate. The inner positions of the two corners of the clamping module are respectively rotatably connected to the first winding wheel and the second winding wheel. The bottom of the top position of the clamping module is fixedly connected to the winding motor. The output end of the winding motor is provided with a winding roller. The winding roller is divided into upper and lower layers. The upper layer of the winding roller is connected to the wire harness passing through the first winding wheel, and the lower layer of the winding roller is connected to the wire harness passing through the second winding wheel. A rotating shaft is provided at the center of the support plate. The two ends of the rotating shaft are rotatably connected to the first bracket in the shape of a U.

[0007] As a further embodiment of this utility model: a power box is bolted to the top of the first bracket, a first motor is mounted on the top of the power box, a drive gear is fixedly connected to the output end of the first motor, a driven gear is fixedly connected to the top of the rotating shaft, and the drive gear meshes with the driven gear.

[0008] As a further improvement of this utility model, the clamping module has symmetrically arranged wire harness channels inside.

[0009] As a further improvement of this utility model, a wire harness fixing hole is vertically provided at the tail of the transmission rod.

[0010] As a further improvement of this utility model, the clamping module is provided with corner avoidance features at its two bottom corner positions.

[0011] As a further improvement of this utility model: the top of the clamping module is symmetrically provided with mounting threaded holes, and the top of the support plate is provided with an internal hexagon bolt that is threadedly connected to the mounting threaded holes.

[0012] As a further improvement of this utility model: the arc-shaped clamping block has an arc-shaped groove in the middle of its arc surface, and the arc-shaped groove is slidably connected to the positioning ring at the center of the tool.

[0013] As a further improvement of this utility model: a protective cover is fixedly connected to the inner side of the first bracket, the protective cover being a cylindrical shell structure with an opening on one side.

[0014] As a further embodiment of this utility model: a second bracket is bolted to the vertical plate of the first bracket, and the second bracket is fixedly connected to the inner wall of the machine tool by bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a spring is provided between the arc-shaped clamping block and the clamping module to clamp the side of the tool with the two arc-shaped clamping blocks. The arc-shaped slot is engaged in the positioning ring of the tool to prevent the tool from sliding up and down. When the tool is replaced, the replacement structure applies pressure to the tool in the vertical direction. The arc-shaped clamping plate will not slide horizontally under the action of the guide rod and the transmission rod to prevent the clamping from loosening. When the tool is released, the winding motor drives the winding roller to rotate, so that the wire harness passes through the first winding wheel and the second winding wheel and pulls the transmission rod to slide horizontally, releasing the clamping of the tool. The tool support function is fully integrated into the clamping module, which is convenient for replacement and maintenance and easy to use.

[0017] 2. In this utility model, when the tool is removed, the winding motor releases the wire harness, eliminating the need to keep the wire harness taut, thus improving the service life of the winding motor. The arc-shaped clamping plates slide under the action of the spring, and the spring returns to its original state. The guide rod slides with the sliding through hole, and the clamping end faces of the two arc-shaped clamping plates fit together, preventing the arc-shaped clamping plates from shaking as the support plate rotates, making it safer to use.

The transmission rod 24 is slidably connected to the clamping module 2. A spring mounting hole 21 is arranged between the two sliding through holes 20. A spring 22 is installed in the spring mounting hole 21 and fits against the back of the arc-shaped clamping plate. The spring 22's elasticity... The clamping module 2 uses two arc-shaped clamping blocks 18 to clamp and fix the tool. The inner positions of the two corners of the clamping module 2 are respectively rotatably connected to the first winding wheel 16 and the second winding wheel 17. The bottom of the top position of the clamping module 2 is fixedly connected to the winding motor 14. The output end of the winding motor 14 is provided with a winding roller 15. The winding roller 15 is divided into upper and lower layers. The upper layer of the winding roller 15 is connected to the wire harness through the first winding wheel 16, and the lower layer of the winding roller 15 is connected to the wire harness through the second winding wheel 17. When the tool is removed, the winding motor 14 releases the wire harness, and it is not necessary to keep the wire harness in a tight state. The clamping surfaces of the two arc-shaped clamping blocks 18 are in contact under the action of the spring 22 to prevent the arc-shaped clamping blocks 18 from sliding. The center position of the support plate 1 is provided with a rotating shaft 10. The two ends of the rotating shaft 10 are rotatably connected to the "U"-shaped first bracket 4. The entire clamping module 2 works independently, is easy to disassemble and maintain, and is convenient to use.

[0028] The top of the first bracket 4 is bolted to a power box 6, and the top of the power box 6 is mounted on a first motor 7. The output end of the first motor 7 is fixedly connected to a drive gear 8, and the top of the rotating shaft 10 is fixedly connected to a driven gear 9. The drive gear 8 and the driven gear 9 mesh, and the power structure is simple, reliable, and easy to maintain.

[0029] The clamping module 2 has symmetrically arranged wire harness channels 19 inside, which allows the wire harness to be pulled within the wire harness channels 19 to prevent external factors from damaging the wire harness.

[0030] The tail of the transmission rod 24 is vertically provided with a wire harness fixing hole 25, which facilitates the installation of the wire harness;

[0031] Among them, the clamping module 2 is provided with corner avoidance 12 at the two bottom corners to prevent the clamping module 2 from interfering with the protective cover 3 during rotation;

[0032] The clamping module 2 is symmetrically provided with mounting threaded holes 13 on its top, and the support plate 1 is provided with an internal hex bolt 11 that is threadedly connected to the mounting threaded holes 13 on its top, which facilitates the disassembly of the clamping module 2.

[0033] Among them, the arc-shaped clamping block 18 has an arc-shaped groove 26 in the middle of its arc surface. The arc-shaped groove 26 is slidably connected to the positioning ring at the center of the tool to improve the clamping performance of the tool.

[0034] The first bracket 4 is fixedly connected to a protective cover 3 to prevent debris from entering the tool magazine during the machining process. The protective cover 3 is a cylindrical shell structure with an opening on one side.

[0035] The first bracket 4 has a second bracket 5 connected to its vertical plate by bolts. The second bracket 5 is fixedly connected to the inner wall of the machine tool by bolts, making the tool magazine easy to install and disassemble.

[0036] The working principle of this utility model is as follows: First, the tool needs to be installed on the clamping module 2. The winding motor 14 on the corresponding clamping module 2 works, and the layered winding rollers 15 pull the wire harness to wind it up. After the wire harness changes direction through the first winding wheel 16 and the second winding wheel 17, it pulls the transmission rod 24 to move, thereby opening the two arc-shaped clamps 18. After the tool is placed between the two arc-shaped clamps 18, the winding motor 14 releases the wire harness. The arc-shaped clamps 18 move in opposite directions under the restoring action of the spring 22. The arc-shaped slot 26 is engaged inside the positioning ring of the tool, and the arc surface of the arc-shaped clamps 18 clamps and fixes the tool. The tool is then placed according to... The tools are sequentially installed on the support plate 1, ensuring secure clamping and safe use throughout the clamping process. During automatic tool changing, the first motor 7 rotates, driving the rotating shaft 10 to rotate under the meshing of gears. This causes the support plate 1 to move the tool to be replaced to the outside of the protective cover 3. The tool replacement structure of the machine tool moves to the tool and engages with it. At this time, the arc-shaped clamping block 18 separates under the action of the winding motor 14, releasing the tool from its fixation. The tool replacement is then complete and easy to use. When the tool support structure malfunctions, the clamping module 2 that needs repair can be disassembled separately for easy maintenance without affecting the normal operation of other tools and other workstations.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
