Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a device for inspecting the dimensions of cutting tools. Background Technology

[0002] Currently, in the lithium battery production and processing process, the cutting of battery tabs is mainly done by mounting a blade onto a blade sleeve fitted on the inner sleeve of the blade sleeve, and then fitting the inner sleeve of the blade sleeve onto the rotating shaft. At the same time, a spacer sleeve fixes the inner sleeve of the blade sleeve to a fixed width on the rotating shaft.

[0003] For example, patent number CN217413176U discloses a cutter spinner structure with fine adjustment function. The cutter shaft is fitted with a cutter spinner inner sleeve, and the cutter spinner inner sleeve has a movable cavity inside. A threaded sleeve is rotatably installed inside the movable cavity, and the cutter spinner inner sleeve has symmetrical through grooves communicating with the movable cavity on the outer side.

[0004] For example, patent number CN120326707A discloses a rotating structure and method, aiming to solve the problem that the cutter disc on the cutter spinner is installed by a hard connection, which can easily damage the cutter disc when the end face runout accuracy of the equipment is not good. This invention includes a cutter spinner seat and a cutter disc, the cutter disc is installed on the cutter spinner seat, a cutter spinner cover is installed on the cutter spinner seat, and a coil spring is installed between the cutter spinner cover and the cutter disc, the coil spring abuts against the cutter disc to provide elastic buffering force to the cutter disc;

[0005] The dimensional accuracy of the die-cutting components directly determines the quality, safety, and production efficiency of the final product. Precise dimensional inspection can detect installation errors or component wear before slitting, avoiding the production of a large number of defective products and reducing material waste and downtime for adjustment.

[0006] While existing methods for inspecting the dimensions of a blade rotor can achieve relatively accurate measurements using digital micrometers or high-precision calipers, the operation process is cumbersome. Furthermore, due to the circular structure of the blade rotor, the measuring tool is difficult to position stably and is prone to slippage or tilting due to improper operation or unstable support, resulting in reading fluctuations and positional shifts, which increases measurement errors and affects inspection efficiency and accuracy. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a cutting tool dimension inspection device, which solves the problems of cumbersome operation process and difficulty in stable positioning of measuring tools due to the circular structure of the cutting tool. The device is prone to slippage or tilting due to improper operation or unstable support, resulting in reading fluctuations and positional deviations, which affect the detection efficiency and accuracy.

[0015] The beneficial effects of this utility model are:

[0016] 1.

[0026] Please see Figures 1-5 This utility model provides an embodiment: a device for inspecting the dimensions of a production cutter, comprising a base 1, a placement platform 2 at the upper end of the base 1, an adjusting seat 3 fixedly installed on the right side of the placement platform 2, a sliding groove 4 on the left side of the adjusting seat 3, a bidirectional lead screw 5 inside the sliding groove 4, a limit plate 6 outside the bidirectional lead screw 5, a top rod 7 at the upper end of the placement platform 2, a pulling plate 8 at the upper end of the top rod 7, a pull ring 9 fixedly installed at the upper end of the pull plate 8, and a sliding... The movable seat 10 has sliding sleeves 11 fixedly installed at both ends. Pull ring 12 is fixedly installed on the outer side of the sliding sleeve 11. Guide rod 13 is provided on the inner side of the sliding sleeve 11. Support plate 14 is fixedly installed on the left side of the upper end of the placement platform 2. Support plate 25 is fixedly installed on the upper end of the adjustment seat 3. Laser range sensor 16 is fixedly installed on the left side of support plate 14. Laser range sensor 27 is fixedly installed on the upper end of the movable seat 10. Data display module 18 is provided on the front side of the base 1.

[0027] Please see Figures 1-4 In this embodiment, the placement platform 2 has an L-shaped structure and is fixedly connected to the upper end of the base 1. The placement platform 2 is tilted with the left side lower than the right side, with an inclination angle of 15°~30°. The front and rear ends of the bidirectional lead screw 5 are rotatably connected to the adjustment seat 3 through bearings. The front end of the bidirectional lead screw 5 extends to the outside of the adjustment seat 3 and is fixedly installed with an adjustment knob 501. There are two limiting plates 6 arranged symmetrically front and back and are threadedly connected to the bidirectional lead screw 5. The right end of the limiting plate 6 is slidably connected to the inner side of the slide groove 4, and the left end of the limiting plate 6 extends to the outside of the adjustment seat 3 and slides against the surface of the placement platform 2. The blade to be tested is placed on the upper end of the tilted placement platform 2. Under the action of gravity, the left end of the blade naturally fits against the support surface of the placement platform 2, realizing one-sided reference positioning. By rotating the adjustment knob 501, the bidirectional lead screw 5 is driven to rotate, driving the two limiting plates 6 to move towards each other along the slide groove 4 and the surface of the placement platform 2 until they are tightly fitted against the front and rear sides of the blade, realizing the centered positioning and clamping of the blade.

[0028] Please see Figures 2-5In this embodiment, the top rod 7 and the surface of the placement platform 2 are vertically arranged, the lower end of the top rod 7 abuts against the surface of the placement platform 2, and the upper end of the top rod 7 and the pull plate 8 are fixedly connected by a partition 801. The top rod 7 has a cylindrical structure design, and the left side of the pull plate 8 and the left end of the top rod 7 are located on the same plane. The moving seat 10 has a through groove 101 that runs vertically through it. The pull plate 8 runs through the through groove 101 and is slidably connected to the inner side of the through groove 101. There are two guide rods 13 arranged parallel to each other front and back. The sliding sleeve 11 is slidably sleeved on the outer side of the guide rod 13. The left end of the guide rod 13 is fixedly connected to the support plate 14, and the right end of the guide rod 13 is fixedly connected to the support plate 15. The right end of the laser rangefinder sensor 16 extends through a through hole to the right side of the support plate 14 and is provided with a probe 1. The lower end of the laser rangefinder sensor 17 extends through a through hole to the lower end of the moving seat 10 and is provided with a probe 2. The laser rangefinder sensor 16, the laser... Both optical ranging sensors 17 and data display module 18 are electrically connected. By pulling the pull ring 12, the sliding sleeve 11 slides along the guide rod 13, causing the moving seat 10 to move the pulling plate 8 and the top rod 7 to move to the left synchronously until the top rod 7 is completely in contact with the left end of the blade. At this time, the laser ranging sensor 16 obtains the outer diameter of the blade by measuring the distance between the support plate 14 and the pulling plate 8. The top rod 7 is lifted upward by the pull ring 9. After adjusting the position of the moving seat 10, the top rod 7 is lowered so that it passes through the center hole of the blade. The moving seat 10 is pushed again so that the right end of the top rod 7 accurately abuts against the left inner wall of the center hole. At this time, the laser ranging sensor 16 remeasures the distance to obtain the annular wall thickness of the blade. By moving the moving seat 10, the laser ranging sensor 17 is moved to any detection position above the blade. Using its non-contact measurement function, the local thickness of different areas on the outer circumference of the blade can be measured.

[0029] During operation, the blade to be tested is placed on the upper end of the inclined placement platform 2. Under the action of gravity, the left end of the blade naturally fits against the support surface of the placement platform 2, achieving lateral reference positioning. By rotating the adjustment knob 501, the bidirectional lead screw 5 is rotated, driving the two limiting plates 6 to move towards each other along the slide groove 4 and the surface of the placement platform 2 until they are tightly fitted against the front and rear sides of the blade, achieving centered positioning and clamping of the blade. By pulling the pull ring 12, the sliding sleeve 11 slides along the guide rod 13, causing the moving seat 10 to move the pulling plate 8 and the top rod 7 to move to the left synchronously until the top rod 7 is completely fitted against the left end of the blade. At this time, the laser range sensor 16 measures the distance between the support plate 14 and the pulling plate 8. The distance between the two sides is used to obtain the outer diameter of the blade spindle. The top rod 7 is lifted upward by the pull ring 9. After adjusting the position of the moving seat 10, the top rod 7 is lowered so that it passes through the center hole of the blade spindle. The moving seat 10 is pushed again so that the right end of the top rod 7 accurately abuts against the left inner wall of the center hole. At this time, the laser range sensor 16 remeasures the distance to obtain the annular wall thickness of the blade spindle. By moving the moving seat 10, the laser range sensor 17 is moved to any detection position above the blade spindle. Using its non-contact measurement function, the local thickness of different areas on the outer circumference of the blade spindle can be measured. All measurement data can be transmitted to the display module 18 in real time for the operator to read and analyze.

[0030] Compared to existing methods of inspecting cutter dimensions using digital micrometers or high-precision calipers, this application utilizes an inclined L-shaped platform 2, where gravity allows the left end of the cutter to naturally conform, achieving rapid and stable single-sided reference positioning. A bidirectional lead screw 5 drives two limiting plates 6 to conform to the front and rear sides of the cutter, achieving centered positioning and clamping. This design effectively avoids slippage, tilting, and reading fluctuations caused by unstable positioning and uneven force during traditional manual measurement, reducing operational errors and improving inspection accuracy. Furthermore, compared to existing methods of measuring different data using multiple methods, this application, through a movable top rod 7 and a laser rangefinder 16, can sequentially measure the outer diameter width and annular wall thickness of the cutter. A movable base 10 drives the laser rangefinder 17 to move, allowing for the measurement of local thickness at any position on the outer circumference of the cutter. This enables the inspection of multiple key dimensions, avoiding frequent tool changes and repeated clamping. It features high integration, comprehensive functionality, and improved inspection efficiency.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
