Description

Technical Field

[0001] This utility model relates to the field of graphite machine technology, and in particular to a graphite machine that facilitates tool replacement. Background Technology

[0002] A graphite machine is a high-precision machine tool specifically designed for processing graphite molds. It features high temperature resistance (allowing stable operation in high-temperature environments), high mechanical strength (capable of withstanding heavy-duty processing), and excellent electrical and thermal conductivity. It uses CNC technology to control the cutting tools for precision cutting of graphite materials and is widely used in mold manufacturing (such as train wheels and precision parts) and chemical equipment (such as graphite heat exchangers and synthesis furnaces). Its processing advantages include high precision (micron-level positioning), high efficiency (automated processing), and a professional dust removal system (reducing graphite dust pollution).

[0003] The existing graphite machine fixtures require frequent replacement during use, resulting in low adjustment efficiency and inconvenience in clamping various types of graphite components. In addition, the traditional graphite machine tool replacement requires disassembling multiple parts, which is complex, inflexible, increases labor costs, and has low maintenance efficiency.

[0004] Therefore, those skilled in the art have provided a graphite machine that facilitates tool replacement to solve the problems mentioned in the background art. Utility Model Content

It is equipped with an adjustment structure that can adjust the position of the clamping block, thereby fixing graphite parts of different widths and heights, expanding the clamping contact surface, improving clamping stability, and is equipped with a disassembly structure that allows for quick tool replacement. The structure is stable, the operation is simple, the operation difficulty is reduced, the downtime is reduced, and the maintenance efficiency is improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A graphite machine for easy tool replacement includes a graphite machine body, a controller is fixedly connected to the front side of the graphite machine body, a telescopic protective cover and a fixed base are fixedly connected inside the graphite machine body, an adjustment structure is provided inside the fixed base, a fixed block is provided inside the graphite machine body, and a disassembly structure is provided inside the fixed block.

[0008] The adjustment structure includes a bidirectional adjustment motor located inside the fixed base. An adjustment threaded rod is fixedly connected to the output end of the bidirectional adjustment motor. A slider is threaded onto the outer side of the adjustment threaded rod. A moving rod is fixedly connected to one side of the slider. A moving plate is fixedly connected to one end of the moving rod. A lifting plate is provided inside the moving plate.

This allows for the control of the fixed block and the cutter to move in all directions.

[0020] Furthermore, the fixed block is provided with a compression groove inside, and a compression spring is provided inside the compression groove.

This allows control over the clamping distance between the clamping blocks, enabling the clamping of graphite parts of varying widths. An electric telescopic rod moves the fourth moving block, which in turn rotates the first and second rotating plates, and consequently moves the third moving block, raising or lowering the lifting plate. This adjusts the height of the clamping blocks to accommodate graphite materials of different heights, preventing clamping failures due to workpiece size differences, increasing the applicability of the device, expanding the clamping contact surface of the clamping blocks, significantly reducing the risk of graphite part displacement during processing, and improving processing accuracy.

[0039] Working principle: When using this graphite machine with easy tool replacement, the telescopic protective cover 2 is raised and lowered by the controller 3 to open the graphite machine body 1. The graphite part is placed on the fixed seat 4. According to the width of the graphite part, the bidirectional adjustment motor 501 is started to drive the adjusting threaded rod 502 to rotate. The rotation of the adjusting threaded rod 502 causes the slider 503 to move along its thread. The slider 503 drives the moving rod 504 to move. The movement of the moving rod 504 drives the moving plate 505 to move, which in turn drives the lifting plate 508 and the clamping block 12 to move and clamp the graphite part. The electric telescopic rod 513 is started to drive the fourth moving block 505 to move. The movement of the clamping block 12 causes the first rotating plate 510 and the second rotating plate 511 to rotate, which in turn causes the third moving block 509 to move, raising or lowering the lifting plate 508 and adjusting the height of the clamping block 12 to accommodate graphite raw materials of different heights. Pressing the pressing rod 1004 forces the misalignment rod 1008 out of the fixed block 11, inserting the tool 20 into the misalignment groove 21. The misalignment groove 21 and the tool 20 engage with each other, initially fixing the position of the tool 20. Releasing the pressing rod 1004, under the force of the lifting spring 1006, the misalignment rod 1008 retracts the top of the tool 20 into the fixed block 11. Inside the tool 20, the tool 20 is further secured. At this time, the locking rod 1012 engages with the slot 22 at the top of the tool 20 under the force of the compression spring 1010, making the tool 20 tightly fixed to the fixing block 11. When disassembly is required, pull the locking rod 1012 to disengage it from the slot 22 at the top of the tool 20, initially unlocking the tool 20. Then, press the pressing rod 1004 to push the misalignment rod 1008 out of the fixing block 11, causing the tool 20 to disengage from the fixing block 11 and be quickly disassembled from the misalignment slot 21. After the tool 20 and the graphite component are fixed, start the first motor 6 to drive the first threaded rod 7 to rotate. The rotation of the first threaded rod 7 causes the first moving block 8 to move back and forth along its thread. The second motor 15 is started to drive the second threaded rod 16 to rotate. The rotation of the second threaded rod 16 causes the second moving block 17 to move left and right along its thread. The height of the cutter 20 is controlled by the hydraulic rod 9, and the rotation motor 18 is started to control the rotation of the cutter 20. Through the coordinated action of these components, the cutter 20 can move and rotate in all directions, thereby processing the graphite raw material. At the same time, the vacuum cleaner 13 is started, and the dust generated during the operation of the graphite machine is quickly absorbed through the dust suction head 14 to maintain the cleanliness of the inside of the graphite machine body 1.
