Description

Technical Field

[0001] This utility model relates to an isostatic pressing trimming machine with a power head and a double-blade holder. Background Technology

[0002] In the isostatic pressing process for ceramics, the trimming step is crucial for ensuring the dimensional accuracy and surface quality of the blank. Traditional trimming methods often employ manual labor or single-tool-holder equipment, resulting in low processing efficiency, poor surface uniformity, and rapid tool wear. Furthermore, existing equipment typically only has a single processing function, requiring roughing and finishing to be performed in separate steps, making it impossible to complete multiple processes in a single setup. This leads to long processing cycles, accumulated positioning errors, and impacts product accuracy and production efficiency. Additionally, the poor chip removal during deep groove cutting with a single tool can cause excessive radial force on the product, leading to blank breakage. Summary of the Invention

[0003] This invention provides an isostatic pressing blank trimming machine with a power head and double tool post to solve the problems existing in the prior art. The roughing process (deep groove machining) uses a disc-shaped tool to solve chip removal problems, reduce radial thrust, and prevent product breakage; the finish turning process follows closely after the roughing tool, performing fine turning to ensure rapid and stable completion of the machining process.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] An isostatic pressing trimming machine with a power head and double tool holder includes a machine base, an X-axis drive unit, a Y-axis drive unit, mounting seats, a roughing tool, a finishing tool, a center pin, and an electric rotary table. The X-axis drive unit is fixed on the machine base, and the electric rotary table is located on one side of the machine base, with the rotation axis of the electric rotary table parallel to the driving direction of the X-axis drive unit. Three mounting seats are fixed at intervals on the straight free ends of the X-axis drive units. A center pin is rotatably connected to one of the mounting seats, and the center pin is coaxial with the rotation axis of the electric rotary table. A Y-axis drive unit is fixed to the other two mounting seats. The finishing tool is fixed to the straight free end of one Y-axis drive unit, and a motor is fixed to the straight free end of the other Y-axis drive unit for driving the roughing tool to rotate.

[0006] Furthermore, the roughing tool is a circular insert with several cutting edges evenly arranged on its circumference.

[0007] Furthermore, the rotation axis of the roughing tool is parallel to the rotation axis of the electric rotary table.

[0008] Furthermore, the finishing knife is made of diamond or ceramic and has a circular cutting edge.

[0009] Furthermore, both the X-axis drive unit and the Y-axis drive unit are electric lead screw structures. The X-axis drive unit is equipped with three sliders, which are respectively fixed to three mounting bases.

[0010] Furthermore, the electric rotary table includes a motor and a circular support platform, wherein the circular support platform is fixed to the rotating shaft of the motor.

[0011] This utility model has the following beneficial effects:

[0012] The advantages of this patent are as follows:

[0013] (1) The roughing tool and the finishing tool are placed on separate tool holders and cut in sequence. The blank can be clamped once to complete both roughing and finishing, eliminating repeated positioning errors and significantly shortening the cycle time.

[0014] (2) The roughing tool has its own rotational power, forming a high-speed cutting of "external grinding", which has a high material removal rate per unit time, and the circumferential cutting edge can be used alternately, thus extending its service life.

[0015] (3) Diamond / ceramic circular blades have sharp and wear-resistant cutting edges. After fine finishing, the surface roughness of the blank is low and the size consistency is good, which reduces the amount of subsequent polishing work.

[0016] (4) The servo motor drives the lead screw, and the feed speed and position are controlled in a closed loop. The processing path can be corrected in real time to adapt to the blanking requirements of blanks with different diameters and lengths. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, this utility model discloses an isostatic pressing trimming machine with a double tool holder and a power head, comprising a machine base 1, an X-axis drive unit 2, a Y-axis drive unit 3, a mounting base 4, a roughing tool 5, a finishing tool 6, an ejector pin 7, and an electric rotary table 8.

[0023] The X-axis drive unit 2 is fixed on the machine base 1, and the electric rotary table 8 is arranged on one side of the machine base 1, with its rotation axis parallel to the driving direction of the X-axis drive unit 2. Three mounting seats 4 are installed at intervals on the slider of the X-axis drive unit 2. The outer mounting seat 4 is rotatably equipped with a ejector pin 7, which is coaxial with the rotation axis of the electric rotary table 8 and is used for axial positioning of the billet. The other two mounting seats 4 are each fixed with a set of Y-axis drive units 3, and the driving direction of the two sets of Y-axis drive units 3 is perpendicular to the driving direction of the X-axis drive unit 2.

[0024] like Figure 2 As shown, the moving end of another Y-axis drive unit 3 is fixedly connected to a finishing cutter 6. The finishing cutter 6 uses a circular blade made of diamond or ceramic, with the cutting edge located on the outer circumference of the blade. It is used to perform fine finishing on the rough-turned surface to improve surface finish and dimensional consistency.

[0025] like Figure 3 As shown, a motor is fixed to the moving end of the Y-axis drive unit 3 near the rotary table 8. The motor output shaft is directly connected to the roughing tool 5, forming a rotatable power head structure. The roughing tool 5 is a disc-shaped insert with several cutting edges evenly distributed on its outer circumference. The cutting edge direction is consistent with the rotation tangent direction, allowing for rough turning of the blank at high speed. The rotation axis of the roughing tool 5 is parallel to the rotation axis of the rotary table 8.

[0026] like Figure 4 As shown, the cutting tool 5's insert is fastened to the tool turret with screws. The tool turret is connected to the motor output shaft by a key, allowing for quick disassembly and replacement. When the cutting edge wears down, simply loosen the screws and rotate the insert to a new cutting edge or replace it with a new insert to restore machining capability, making maintenance convenient.

[0027] During operation, the billet is placed on the circular support platform of the rotary table 8. The ejector pin 7 extends and presses against the center hole of the billet to achieve axial positioning. The rotary table 8 drives the billet to rotate at a constant speed. The X-axis drive unit 2 moves synchronously according to a preset trajectory. First, it drives the Y-axis drive unit 3, which is equipped with a roughing tool 5, to approach the billet. The motor starts and drives the roughing tool 5 to rotate at high speed to rough-turn the outer circle of the billet. After the rough turning is completed, the Y-axis drive unit 3 retracts, and at the same time, the Y-axis drive unit 3 equipped with a finishing tool 6 feeds in. The finishing tool 6 contacts the surface of the billet and completes the finishing process during the rotation of the billet. The entire process completes both rough turning and finishing in one clamping, avoiding repeated positioning errors and significantly improving processing efficiency and surface quality.

[0028] Both the X-axis drive unit 2 and the Y-axis drive unit 3 adopt an electric lead screw structure, driven by a servo motor, which can achieve high-precision position control and speed adjustment to ensure accurate machining trajectory. The rotary table 8 is directly driven by a servo motor to rotate the circular support table. The rotation speed can be adjusted in real time according to different materials and processing requirements to adapt to the processing needs of various specifications of blanks.

[0029] This invention realizes integrated rough turning and finish turning, reduces equipment footprint and process switching time, and improves the processing efficiency and finished product quality of isostatic pressing billets.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
