Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter clamping technology, and in particular to a milling cutter clamping structure that facilitates milling cutter production. Background Technology
[0002] Milling cutters are a common machining tool used in the cutting of parts. During the production process, a grooving device is usually used to cut grooves on the side walls of the milling cutter. Milling cutters are mostly used on CNC lathes. The milling cutter is made of a single piece of cutter body and cutting teeth. The cutting teeth are supported by carbide or other wear-resistant tool materials and brazed onto the cutter body. During the production process, the milling cutter needs to be inspected after machining to prevent problems such as weak welds or irregular tooth edges. When inspecting the milling cutter, a clamping structure is needed to fix the milling cutter to facilitate the inspection by the operator.
[0003] However, existing methods for clamping and inspecting milling cutters cannot change the clamping angle, making it impossible to cover all angles for inspection. The cutting edge, coating, and geometric parameters (such as helix angle, rake angle, and clearance angle) of milling cutters (e.g., end mills, ball end mills) need to be measured from different angles (e.g., optical projection, coordinate measuring machine). If the clamping angle is fixed, obstructions or viewing angle limitations may prevent the inspection equipment from capturing some cutting edges, tips, or complex surfaces, creating blind spots and affecting the accuracy, comprehensiveness, and efficiency of the inspection. Utility Model Content
[0004] The purpose of this utility model is to provide a milling cutter clamping structure that facilitates the production of milling cutters, so as 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 milling cutter clamping structure for easy milling cutter production includes a base plate and two upright plates. The base plate is horizontally positioned, and the two upright plates are symmetrically arranged on the base plate. An angle adjustment mechanism is provided on the base plate, which slides on the base plate and is in sliding engagement with the two upright plates. The angle adjustment mechanism is provided with a fixed clamping mechanism for clamping the milling cutter. The fixed clamping mechanism is provided with a plurality of secondary clamping mechanisms arranged at equal intervals, which are in sliding engagement with the fixed clamping mechanism.
[0007] A further technical solution includes an adjusting electric cylinder, a slider, an adjusting rotating plate, a rotating shaft, two rotating wheels, and two slide rails. The two slide rails are symmetrically arranged on the top of the base plate. The adjusting electric cylinder is horizontally arranged on the base plate. The slider is located between the two slide rails, with both ends of the slider slidingly engaged with the two slide rails respectively. The telescopic end of the adjusting electric cylinder is connected to the slider. The slider is L-shaped. The rotating shaft is horizontally fixedly connected to the bottom of the adjusting rotating plate. The top of the slider is rotatably connected to the bottom of the adjusting rotating plate. The two rotating wheels are rotatably connected to both ends of the rotating shaft respectively. Each vertical plate is provided with an inclined groove, and the rotating wheels slide within the inclined groove. The adjusting rotating plate rotates within the two vertical plates.
[0008] A further technical solution involves providing a horizontal plate between the two vertical plates, with two support columns on the horizontal plate to support the adjustment and rotation plate.
[0009] A further technical solution is provided, wherein the fixed clamping mechanism includes a fixed lead screw shaft, a fixed moving plate and two slide rods. The two slide rods are symmetrically arranged on the top of the adjusting rotating plate. The fixed moving plate is slidably engaged with the two slide rods. The fixed lead screw shaft is rotatably connected to the top of the adjusting rotating plate. The fixed lead screw shaft is threadedly connected to the fixed moving plate. The fixed moving plate and the adjusting rotating plate are respectively provided with a plurality of fixed semi-circular grooves arranged at equal intervals.
[0010] In a further technical solution, the radius or depth of several of the fixed semicircular grooves is set differently according to the specifications of the milling cutter.
[0011] In a further technical solution, each of the secondary clamping mechanisms includes a rotating lead screw shaft, a turntable, a fixed plate, a clamping plate, and several springs. The rotating lead screw shaft is rotatably connected to the top of the fixed plate and threadedly connected to the fixed moving plate. The turntable is connected to the top of the rotating lead screw shaft. The fixed plate is located in the fixed semicircular groove of the fixed moving plate, and several springs are connected between the fixed plate and the clamping plate.
[0012] A further technical solution is that the bottom of the clamping plate is provided with several equally spaced protective textures.
[0013] The beneficial effects of this utility model are:
[0014] When adjusting the position of the file being inspected, this invention uses an electric cylinder to drive a slider to move horizontally within two slide rails. This movement of the slider causes a rotating shaft to rotate on it, resulting in two rotating wheels rotating within two inclined grooves. This, in turn, adjusts the angle of the adjusting rotating plate between the two vertical plates, allowing the plate to stop at any position between 0 and 90 degrees. When inspecting a file, the file can be stopped and inspected at any position between 0 and 90 degrees. This allows for changing the angle of file inspection, improving inspection accuracy, efficiency, and adaptability.

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Please refer to Figure 1-6 As shown; this utility model provides a milling cutter clamping structure technical solution for easy milling cutter production: a milling cutter clamping structure for easy milling cutter production includes a base plate 1 and two upright plates 11. The base plate 1 is horizontally arranged, and the two upright plates 11 are symmetrically arranged on the base plate 1. An angle adjustment mechanism 2 is provided on the base plate 1. The angle adjustment mechanism 2 slides on the base plate 1 and is slidably engaged with the two upright plates 11. The angle adjustment mechanism 2 is provided with a fixed clamping mechanism 3 for clamping the milling cutter. The fixed clamping mechanism 3 is provided with a plurality of secondary clamping mechanisms 5 arranged at equal intervals. The secondary clamping mechanisms 5 are slidably engaged with the fixed clamping mechanism 3.
[0025] In this implementation, refer to Figure 3 and Figure 4 As shown, the angle adjustment mechanism 2 includes an adjustment cylinder 20, a slider 21, an adjustment rotating plate 22, a rotating shaft 23, two rotating wheels 24, and two slide rails 25. The two slide rails 25 are symmetrically arranged on the top of the base plate 1. The adjustment cylinder 20 is horizontally arranged on the base plate 1. The slider 21 is between the two slide rails 25, and both ends of the slider 21 are slidably engaged with the two slide rails 25 respectively. The telescopic end of the adjustment cylinder 20 is connected to the slider 21. The slider 21 is L-shaped. The rotating shaft 23 is horizontally fixedly connected to the bottom of the adjustment rotating plate 22. The top of the slider 21 is rotatably connected to the bottom of the adjustment rotating plate 22. The two rotating wheels 24 are rotatably connected to both ends of the rotating shaft 23 respectively. Each vertical plate 11 is provided with an inclined groove 12. The rotating wheels 24 slide in the inclined groove 12. The adjustment rotating plate 22 rotates within the two vertical plates 11.
[0026] When adjusting the position of the file being inspected, the adjusting electric cylinder 20 drives the slider 21 to move horizontally within the two slide rails 25. The movement of the slider 21 causes the rotating shaft 23 to rotate on the slider 21, thereby causing the two rotating wheels 24 to rotate within the two inclined grooves 12 respectively. This causes the angle of the adjusting rotating plate 22 to be adjusted between the two vertical plates 11, allowing the adjusting rotating plate 22 to stop at any position between 0 and 90 degrees. When inspecting the file, the file can be stopped at a position between 0 and 90 degrees for inspection. The angle of the file inspection can be changed, which can improve the inspection accuracy, increase the inspection efficiency, and enhance the adaptability of the inspection.
[0027] Improving Inspection Accuracy: Traditional fixed-angle inspection struggles to fully capture the geometric features of a file, resulting in blind spots. This adjustable structure allows the file to stop at any angle between 0 and 90 degrees, ensuring the inspection equipment can collect data from multiple perspectives and avoiding measurement deviations caused by angle limitations. For example, when inspecting the cone angle of a conical file, the file can be adjusted to the optimal inspection angle, significantly reducing measurement errors. Furthermore, angle adjustment also reduces errors caused by factors such as gravitational deformation and inconsistent inspection standards, ensuring the accuracy of the inspection results.
[0028] Improved inspection efficiency: This structure features angle indexing, allowing multiple angles to be preset in a single clamping operation. This enables multi-feature inspection of the file, reducing the number of repeated clamping operations and avoiding cumulative errors caused by repeated clamping. In automated inspection lines, it can be linked with the conveyor line to achieve a rapid "angle adjustment-inspection-reset" cycle, significantly shortening the inspection cycle. Compared to traditional manual indexing inspection, efficiency is significantly improved, effectively enhancing overall inspection efficiency and meeting batch inspection requirements.
[0029] Enhanced Detection Adaptability: Different types of files and detection items have different requirements for detection angles. This adjustment structure can flexibly adapt to the complex structures of various files, whether they have spiral grooves, cross grooves, or beveled file handles, achieving accurate detection through angle adjustment. Furthermore, this structure can adjust the file to the optimal working angle of the sensor according to different detection equipment and processes, ensuring that the performance of the detection equipment is fully utilized and expanding the applicability of the detection equipment.
[0030] In this embodiment, a horizontal plate 26 is provided between the two vertical plates 11, and two support columns 27 are provided on the horizontal plate 26 to support the adjustment and rotation plate 22.
[0031] When the adjusting rotating plate 22 is in a horizontal position, the end of the adjusting rotating plate 22 is located on two support columns 27, and the two support columns 27 support the bottom of the adjusting rotating plate 22.
[0032] In this implementation, refer to Figure 5 As shown, the fixed clamping mechanism 3 includes a fixed lead screw shaft 31, a fixed moving plate 32, and two slide rods 33. The two slide rods 33 are symmetrically arranged on the top of the adjusting rotating plate 22. The fixed moving plate 32 is slidably engaged with the two slide rods 33. The fixed lead screw shaft 31 is rotatably connected to the top of the adjusting rotating plate 22. The fixed lead screw shaft 31 and the fixed moving plate 32 are threadedly connected. The fixed moving plate 32 and the adjusting rotating plate 22 are respectively provided with a plurality of fixed semi-circular grooves 4 arranged at equal intervals.
[0033] When clamping the file, the file is placed horizontally in the fixed semi-circular groove 4 of the adjusting rotating plate 22. Then, the fixed lead screw shaft 31 is rotated on the adjusting rotating plate 22, which will drive the position of the fixed moving plate 32 to move downward on the two sliding rods 33. The fixed semi-circular grooves 4 on the fixed moving plate 32 are aligned and moved with the fixed semi-circular grooves 4 on the adjusting rotating plate 22, thereby clamping and fixing the position of the file so that the position of the file can be fixed when the file is tested.
[0034] In this embodiment, the radius or depth of several of the fixed semicircular grooves 4 are set differently according to the specifications of the milling cutter; the type of fixed semicircular groove 4 can be a semicircular groove with different radii, which can fix circular files of different diameters; the fixed semicircular groove 4 can be a rectangular groove, which can fix rectangular files. When clamping and testing the files, it is possible to perform testing work on different types of files.
[0035] In this implementation, refer to Figure 6 As shown, each of the secondary clamping mechanisms 5 includes a rotating lead screw shaft 51, a turntable 52, a fixed plate 53, a clamping plate 54, and several springs 55. The rotating lead screw shaft 51 is rotatably connected to the top of the fixed plate 53 and threadedly connected to the fixed moving plate 32. The turntable 52 is connected to the top of the rotating lead screw shaft 51. The fixed plate 53 is located in the fixed semicircular groove 4 of the fixed moving plate 32. Several springs 55 are connected between the fixed plate 53 and the clamping plate 54. The springs 55 are located between the fixed plate 53 and the clamping plate 54. When the clamping plate 54 moves downward to contact the file or milling cutter, the springs 55 absorb the impact energy of the clamping force through compression deformation, forming a flexible contact rather than rigid compression. When files of different types / sizes, such as those with different shank diameters, are installed in the fixed semicircular groove 4, the elastic deformation of the springs 55 can automatically adapt to the actual size of the file, filling the gap between the fixed semicircular groove 4 and the file shank.
[0036] When the file is clamped and fixed by moving the fixed moving plate 32 downward, the position of the file will deviate due to the different sizes of the fixed semicircular grooves 4. At this time, depending on the type and size of the file, the rotating turntable 52 will drive the rotating lead screw shaft 51 to rotate on the fixed moving plate 32, thereby driving the fixed plate 53 to move downward and the clamping plate 54 to move downward, and perform secondary clamping and fixing of the file in the fixed semicircular groove 4. This can eliminate the initial gap of the fixed semicircular groove 4, thereby achieving direct contact between the clamping plate 54 and the file to fix the position of the file.
[0037] The core advantage of secondary clamping and fixing of files lies in overcoming the limitations of a single fixing structure through the combination of "initial coarse positioning + secondary fine calibration", which significantly improves clamping accuracy, stability and compatibility.
[0038] In this embodiment, the bottom of the clamping plate 54 is provided with a number of equally spaced protective textures 56; the protective textures 56 are rubber protrusions that ensure that when the clamping plate 54 comes into contact with the file, it will not slip and affect the fixation of the file.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
