Description

Technical Field

[0001] This utility model relates to the field of tool setting technology, and in particular to a low-cost CNC tool length setting tool. Background Technology

[0002] A tool setter is a device used to adjust cutting tools. During the machining process, auxiliary time such as workpiece loading and unloading and tool adjustment accounts for a considerable proportion of the machining cycle. Among them, tool adjustment is both time-consuming and labor-intensive, and its accuracy is insufficient, so a tool setter is needed to assist in the process.

[0003] Existing tool setters have the following disadvantages:

[0004] 1. Existing traditional tool setting devices are expensive, making them unaffordable for small and medium-sized manufacturers and the vast number of end-users;

[0005] 2. Mechanical tool setting blocks have a complex structure, rely on precision-machined components (such as fine-tuning screws and high-precision sensors), and have high maintenance costs;

[0006] 3. The accuracy of contact-type tool setting is greatly affected by human operation;

[0007] 4. Most tool setters on the market have low precision.

[0008] There is a need for a tool setter that is low in cost, easy to operate, and has higher accuracy and stability, which can solve the problems mentioned above. Utility Model Content

[0009] This invention provides a low-cost CNC tool length setter. By technically modifying existing tool setters, it solves the problems of high cost and insufficient detection accuracy of existing tool setters.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A low-cost CNC tool length setter includes a base sleeve, a tool setting sleeve, a tool setting platform, a detection axis, an elastic reset mechanism, and a photoelectric detection module. The base sleeve is fixedly mounted on the worktable. A sleeve seat is provided in the middle of the base sleeve, and an elastic reset mechanism is installed inside the sleeve seat. The tool setting sleeve is located above the base sleeve and is movably connected to the base sleeve through the elastic reset mechanism. A tool setting platform is embedded on the upper surface of the tool setting sleeve, and the tool setting platform is positioned directly opposite the tool tip. A detection axis is also fixedly mounted at the bottom of the tool setting sleeve. A through hole is opened at the bottom of the sleeve seat, and the detection axis passes through the through hole from top to bottom. A photoelectric detection module for detecting the tool is located at the bottom of the base sleeve below the through hole.

[0012] Preferably, the base sleeve and the tool setting sleeve are made of engineering plastic.

[0013] Preferably, the elastic reset mechanism includes an integrated spring and a guide sleeve. The upper end of the integrated spring abuts against the bottom surface of the inner cavity of the tool setting sleeve, and the lower end of the integrated spring abuts against the bottom surface of the sleeve seat. The guide sleeve is installed inside the sleeve seat, and the detection shaft passes through the guide sleeve.

[0014] Preferably, the inner side of the inner cavity of the tool sleeve is provided with an anti-deflection limiting groove, and the outer side of the base sleeve is also provided with a protruding part, which is fitted into the anti-deflection limiting groove.

[0015] Preferably, a dustproof structure is also provided between the base sleeve and the tool setting sleeve.

[0016] Preferably, the dustproof structure includes a 60ppi polyurethane dustproof sleeve, which is fitted and installed on the outer periphery of the sleeve seat, with the outer side of the 60ppi polyurethane dustproof sleeve abutting against the inner side of the tool setting sleeve.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model uses engineering plastic injection molding for the tool setting sleeve and base sleeve, resulting in lower manufacturing costs. The tool setting sleeve has an anti-deflection limiting groove on its inner side, and the base sleeve has a protruding part on its outer side. The base sleeve is fixedly mounted on the profile platform. The anti-deflection limiting groove limits the movement of the tool setting sleeve, ensuring it can only move vertically, eliminating horizontal swaying errors and improving detection accuracy.

[0019] This application incorporates a polyurethane dustproof gasket and an integrated spring between the base sleeve and the tool setting sleeve to form a double buffer structure. This structure can absorb impact force in stages, prevent tool bounce, further improve detection accuracy, and enhance tool setting performance. Attached Figure Description

Detailed Implementation

[0026] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1-5 As shown, this utility model provides a low-cost CNC tool length setting device, including a base sleeve 1, a tool setting sleeve 2, a tool setting platform 3, a detection shaft 4, an elastic reset mechanism 5, and a photoelectric detection module 6. The base sleeve 1 is fixedly installed on the worktable. A sleeve seat 11 is provided in the middle of the base sleeve 1, and an elastic reset mechanism 5 is installed inside the sleeve seat 11. The tool setting sleeve 2 is provided above the base sleeve 1. The tool setting sleeve 2 is movably connected to the base sleeve 1 through the elastic reset mechanism 5. The tool setting platform 3 is embedded on the upper surface of the tool setting sleeve 2. The tool setting platform 3 is positioned directly opposite the tool tip. A detection shaft 4 is also fixedly installed at the bottom of the tool setting sleeve 2. A through hole is opened at the bottom of the sleeve seat 11, and the detection shaft 4 passes through the through hole from top to bottom. A photoelectric detection module 6 for detecting the tool is provided at the bottom of the base sleeve 1 below the through hole.

[0028] The following steps are included when using the tool according to this application:

[0029] S1. Fix the tool setter on the table;

[0030] S2. The machine tool spindle clamps the tool to be tested and moves it above the tool setter.

[0031] S3 and Z-axis slowly move down. When the tool tip touches the tool setting platform 3, the pressure triggers the detection axis 4 to move downward, and the photoelectric detection module 6 identifies and detects it.

[0032] S4. The main control equipment automatically calculates the tool length, which is the tool length compensation value;

[0033] S5. After release, the elastic reset mechanism 5 automatically resets, ready for the next measurement.

[0034] The photoelectric detection module 6 provided in this application can be triggered instantaneously upon tool contact to detect the tool displacement length. The tool setting platform 3 is made of tungsten carbide tungsten steel hard alloy and is processed with a precision mirror finish. The tool setting platform 3 is nested in the tool setting sleeve 2 and contacts the tool tip. The tool setting platform 3 can drive the base sleeve 1 and the detection shaft 4 to move downwards.

[0035] Furthermore, the base sleeve 1 and the tool setting sleeve 2 are made of engineering plastic, which reduces the manufacturing cost. The base sleeve 1 is fixed to the workbench by threaded installation and has a foolproof design, making installation more convenient.

[0036] Furthermore, to ensure that the base sleeve 1 can automatically reset after use, the elastic reset mechanism 5 includes an integrated spring 51 and a guide sleeve 52. The upper end of the integrated spring 51 abuts against the bottom surface of the inner cavity of the tool setting sleeve 2, and the lower end of the integrated spring 51 abuts against the bottom surface of the sleeve seat 11. The guide sleeve 52 is installed inside the sleeve seat 11, and the detection shaft 4 passes through the guide sleeve 52. The elastic reset mechanism 5 ensures that the tool setting platform 3 resets vertically after being pressed, thus eliminating lateral offset.

[0037] Furthermore, the inner side of the inner cavity of the tool setting sleeve 2 is provided with an anti-deflection limiting groove 21, and the outer side of the base sleeve 1 is also provided with a protruding part 12, which is fitted into the anti-deflection limiting groove 21. The anti-deflection limiting groove 21 can prevent rotation from damaging the internal structure and has a guiding function, and can also prevent the tool setting sleeve 2 from being damaged by overpressure.

[0038] Furthermore, in order to achieve a better dustproof sealing effect, a dustproof structure 7 is also provided between the base sleeve 1 and the tool setting sleeve 2.

[0039] Furthermore, the dustproof structure 7 includes a 60ppi polyurethane dust cover, which is fitted and installed on the outer periphery of the sleeve base 11, with the outer surface of the 60ppi polyurethane dust cover abutting against the inner surface of the tool setting sleeve 2. The 60ppi polyurethane dust cover is embedded in the upper edge of the base sleeve 1, covering the gap between the tool setting sleeve 2 and the base sleeve 1, and forms a negative pressure airflow to block dust when it elastically resets.

[0040] The tool setting sleeve 2 and the base sleeve 1 of this utility model are made of engineering plastic injection molding, which reduces the manufacturing cost. The inner side of the inner cavity of the tool setting sleeve is provided with an anti-deflection limiting groove 21, and the outer side of the base sleeve 1 is also provided with a protrusion 12. The base sleeve 1 is fixedly installed on the profile platform. The anti-deflection limiting groove 21 can limit the tool setting sleeve 2, so that the tool setting sleeve 2 can only move in the vertical direction, eliminating horizontal sway error and improving detection accuracy.

[0041] This application incorporates a polyurethane dustproof gasket and an integrated spring 51 between the base sleeve 1 and the tool setting sleeve 2 to form a double buffer structure. This structure can absorb impact force in stages, prevent tool bounce, further improve detection accuracy, and achieve better tool setting results.
