[0001] The present invention relates to the technical field of cutting equipment, and in particular to a locking mechanism and a locking method. Background Art

[0002] Cutting equipment is a type of mechanical equipment used for cutting, including lathes, milling machines, and magnetic drills. After the magnetic drill is connected to a power source, the magnetic base can generate a strong magnetic force, allowing the magnetic drill to be adsorbed on the workpiece for drilling, which is conducive to promoting the miniaturization of cutting equipment.

[0003] In order to adapt to different cutting requirements and increase cutting adaptability, cutting equipment generally needs to lock and clutch the feed mechanism. The specific steps are as follows: first, use the locking tool and the locking mechanism of the cutting equipment to position the locking tool, then use the locking tool to rotate the locking mechanism to lock it, and finally take out the locking tool, resulting in low locking efficiency, which in turn leads to low cutting efficiency of the cutting equipment. Summary of the Invention

[0032] Example 1

[0033] Combined with attachment Figure 1-3 , this embodiment provides a locking mechanism, including:

[0034] Shaft 1, shaft 1 has through holes 11 evenly distributed along the radial direction;

[0035] Spring 2, one end of the spring 2 is connected to the shaft 1, and the other end of the spring 2 is provided with a limiter 3;

[0036] A shaft 2 4 is rotatably connected to the shaft 1 1 , and a groove 1 41 and a groove 2 42 are radially provided on the shaft 2 4 to cooperate with the limiting body 1 3 ;

[0037] A housing 5 is sleeved on the outer side of the shaft 1, and a groove 3 51 is provided in the housing 5;

[0038] The second limiting body 6 is movably connected to the through hole 11.

[0039] Specifically, the through hole 11 is supported by the shaft 1, which can ensure the stability of the through hole 11. Since the limiting body 26 is movably connected in the through hole 11, the through hole 11 is used to accommodate the limiting body 26, which ensures the stability of the limiting body 26. Among them, the through holes 11 are evenly distributed along the radial direction of the shaft 1, which can ensure the symmetry of the shaft 1; the groove 2 42 is supported by the shaft 2 4, which can ensure the stability of the groove 2 42. The groove 2 42 is used to accommodate the limiting body 26. When the limiting body 26 is located in the groove 2 42, the shaft 1 and the housing 5 can move relative to each other. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic base drill, the housing 5 is equivalent to the cutting equipment body and is in a fixed state. , shaft 1 is in a rotatable state, at this time the feed mechanism is in a clutch state; groove three 51 is used to accommodate the limiting body 2 6. When the limiting body 2 6 is located in the groove three 51, shaft 1 and housing 5 cannot move relative to each other, that is, shaft 1 and housing 5 are in a locked state. If the locking mechanism is used for cutting equipment such as a lathe, milling machine or magnetic base drill, the housing 5 is equivalent to the cutting equipment body, which is in a fixed state, and shaft 1 is in a non-rotatable state. At this time, the feed mechanism is in a locked state. In order to increase the fault tolerance and ensure the symmetry of the housing 5, multiple grooves 3 51 can be evenly distributed along the radial direction of the housing 5. The specific number of grooves 3 51 is not limited and can be determined according to the processing and manufacturing requirements. , cost and other factors are comprehensively considered; the groove 1 41 is supported by the shaft 2 4, which can ensure the stability of the groove 1 41, and the groove 1 41 is used to cooperate with the limit body 1 3, so that the shaft 1 and the shaft 2 4 are relatively fixed. If the locking mechanism is used for cutting equipment such as lathes, milling machines or magnetic drilling machines, it can prevent the shaft 1 and the shaft 2 4 from rotating relative to each other when the feed mechanism is engaged or locked; the spring 2 is supported by the shaft 1, which can ensure the stability of the spring 2. The spring 2 is used to connect the limit body 1 3 to drive the limit body 3 to do telescopic movement, so that the limit body 3 and the groove 1 41 are matched or separated, wherein the limit body 1 3 and the limit body 2 6 can be spherical bodies, Ellipsoid or columnar, etc., the spherical body makes the surface of the limiting body 1 3 and the limiting body 2 6 round and smooth, which is convenient for the limiting body 1 3 and the groove 1 41 to be matched or separated, and at the same time, it is convenient for the limiting body 2 6 and the groove 2 42 to be matched or separated, or the limiting body 2 6 and the groove 3 51 to be matched or separated, and the limiting efficiency is high. The ellipsoidal body makes the volume of the limiting body 1 3 located in the groove 1 41 large, and at the same time makes the volume of the limiting body 2 6 located in the groove 2 42 or the groove 3 51 large, and the limiting stability is good. The columnar body makes the contact area between the limiting body 1 3 and the groove 1 41 large, and at the same time makes the contact area between the limiting body 2 6 and the groove 2 42 or the groove 3 51 large, and the limiting stability is good.

[0040] Therefore, it is only necessary to rotate shaft 2 4 so that the limiting body 2 6 and groove 2 42 or groove 3 51 cooperate. If the locking mechanism is used for cutting equipment, the feeding mechanism can be locked or clutched without the aid of locking tools, and the locking efficiency is high. At the same time, the limiting body 1 3 and groove 1 41 cooperate. If the locking mechanism is used for cutting equipment such as lathes, milling machines or magnetic drilling machines, it can prevent shaft 1 1 and shaft 2 4 from rotating relative to each other when the feeding mechanism is locked or clutched.

[0041] The specific locking method is: rotating shaft 2 4 so that the limiting body 2 6 and groove 2 42 cooperate, and the limiting body 1 3 and the first groove 1 411 of groove 1 41 cooperate, at this time, shaft 1 and housing 5 can move relative to each other. If the locking mechanism is used for cutting equipment such as a lathe, milling machine or magnetic base drilling machine, the feed mechanism of the cutting equipment is in a clutch state at this time; rotating shaft 2 4 so that the limiting body 2 6 and groove 3 51 cooperate, and the limiting body 1 3 and the second groove 1 412 of groove 1 41 cooperate, at this time, shaft 1 and housing 5 cannot move relative to each other, that is, shaft 1 and housing 5 are in a locked state. If the locking mechanism is used for cutting equipment such as a lathe, milling machine or magnetic base drilling machine, the feed mechanism of the cutting equipment is in a locked state at this time.

[0042] Furthermore, groove 1 41 includes a first groove 1 411 arranged opposite to groove 2 42 and a second groove 1 412 located between adjacent first grooves 411 . Both the first groove 1 411 and the second groove 1 412 cooperate with the limiting body 1 3 , and both the first groove 1 411 and the second groove 1 412 are arranged on shaft 2 4 .

[0043] Specifically, the first groove 411 is supported by the shaft 4 to ensure the stability of the first groove 411. Since the first groove 411 and the groove 42 are arranged opposite to each other, that is, when the groove 42 rotates 180 degrees, the line connecting the centers of the first groove 411 and the groove 42 is parallel to the shaft 4, so that when the limiting body 6 and the groove 42 are matched, the limiting body 3 and the first groove 411 are matched. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic base drill, the feed mechanism can be prevented from being locked. When in the clutch state, shaft 1 and shaft 2 4 rotate relative to each other; the second groove 1 412 is supported by shaft 2 4, which can ensure the stability of the second groove 1 412. Since the second groove 1 412 is located between the adjacent first groove 1 411, when the limit body 2 6 and the groove 3 51 cooperate, the limit body 1 3 and the second groove 1 412 cooperate. If this locking mechanism is used in cutting equipment such as lathes, milling machines or magnetic base drilling machines, it can prevent shaft 1 and shaft 2 4 from rotating relative to each other when the feed mechanism is in the locked state.

[0044] Furthermore, along the axial direction of shaft 1, the shapes of the first groove 411 and the second groove 412 are both V-shaped.

[0045] Specifically, the V-shape makes the openings of the first groove 411 and the second groove 412 larger, which facilitates the matching or separation of the first groove 411 and the limiting body 3, and facilitates the matching or separation of the second groove 412 and the limiting body 3.

[0046] Furthermore, the second shaft has a plurality of second grooves 42 evenly distributed along the radial direction.

[0047] Specifically, in order to increase the fault tolerance and ensure the symmetry of the shaft 2 4 , multiple grooves 42 can be evenly distributed along the radial direction of the shaft 2 4 . The specific number of grooves 42 is not limited and can be determined based on comprehensive considerations of processing, manufacturing, cost and other factors.

[0048] Furthermore, shaft one 1 and shaft two 4 are connected via an axial limit member 7 .

[0049] Specifically, the axial limiter 7 is used to limit the axial movement of shaft 1 and shaft 2 4, and to ensure radial rotation of shaft 1 and shaft 2 4. The axial limiter 7 can be a flat head screw, a countersunk screw or a round head screw, etc. Among them, the flat head screw makes it easy to use the axial limiter 7 with a gasket to facilitate vibration reduction, the countersunk screw makes the axial limiter 7 subject to greater force, and the round head screw makes the axial limiter 7 easy to disassemble.

[0050] Furthermore, a matching portion 12 is provided on the shaft 1.

[0051] Specifically, shaft 1 is usually used as an output end, and mating portion 12 facilitates the mating of shaft 1 with an actuator of a cutting device such as a lathe, a milling machine, or a magnetic drilling machine.

[0052] Furthermore, the volume of the first limiting body 3 is smaller than the volume of the second limiting body 6 .

[0053] Specifically, the limiter 1 3 is used to prevent the relative rotation of the shaft 1 and the shaft 2 4. The relatively small volume can make the limiter 1 3 withstand a relatively small force. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic drilling rig, it can prevent the relative rotation of the shaft 1 and the shaft 2 4 when the feed mechanism is in the clutch or locked state; the limiter 2 6 is used to prevent the relative rotation of the shaft 1 and the housing 5. The relatively large volume can make the limiter 2 6 withstand a relatively large force. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic drilling rig, it can prevent the relative rotation of the shaft 1 and the housing 5 when the feed mechanism is in the locked state.

[0054] Furthermore, both the limiting body 1 3 and the limiting body 2 6 are spherical.

[0055] Specifically, the spherical body makes the surface of the limiter 1 3 and the limiter 2 6 round and smooth, which facilitates the matching or separation of the limiter 1 3 and the groove 1 41, and the matching or separation of the limiter 2 6 and the groove 2 42, or the matching or separation of the limiter 2 6 and the groove 3 51.

[0056] Specifically, chromium stainless steel makes the limiting body 1 3 and the limiting body 2 6 have good corrosion resistance, and chromium-nickel stainless steel not only makes the limiting body 1 3 and the limiting body 2 6 have good corrosion resistance, but also makes the limiting body 1 3 and the limiting body 2 6 have high strength.

[0057] Example 2

[0058] Combined with attachment Figure 1-3 This embodiment provides a locking method, which, according to the technical solution of embodiment 1, includes:

[0059] Rotate the second shaft 4 so that the second limiting body 6 and the second groove 42 are matched, so that the first limiting body 3 and the first groove 411 of the groove 41 are matched; or,

[0060] The second shaft 4 is rotated to make the second limiting body 6 and the third groove 51 cooperate, so that the first limiting body 3 and the second groove 1 412 of the groove 1 41 cooperate.

[0061] Specifically, the shaft 2 4 is rotated so that the limiting body 2 6 and the groove 2 42 cooperate, and the limiting body 1 3 and the first groove 1 411 of the groove 1 41 cooperate. At this time, the shaft 1 and the housing 5 can move relative to each other. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic base drill, the feed mechanism of the cutting equipment is in a clutch state at this time; the shaft 2 4 is rotated so that the limiting body 2 6 and the groove 3 51 cooperate, and the limiting body 1 3 and the second groove 1 412 of the groove 1 41 cooperate. At this time, the shaft 1 and the housing 5 cannot move relative to each other, that is, the shaft 1 and the housing 5 are in a locked state. If the locking mechanism is used for cutting equipment such as a lathe, a milling machine or a magnetic base drill, the feed mechanism of the cutting equipment is in a locked state at this time.

[0062] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
