Description

Technical Field

[0001] The utility model relates to the field of file structures, in particular to a file handle and a file with an intelligent horizontal detection and alarm function. Background Art

[0002] Traditional files only have a handle and a blade, without a horizontal detection function. For file users and beginners, they can only control the level of the file through the feeling and experience in their hands. Especially for beginners, due to lack of experience in using files, they are likely to mistake the state where the file is not kept horizontal for the state where the file is kept horizontal, and train themselves in the wrong posture for a long time; for experienced users, whether the file is kept horizontal can only be determined according to their own experience, and it is difficult to ensure that the processing of each part meets the technical requirements.

[0003] Therefore, those skilled in the art have made many improvements to files and their related configurations to remind the operator to keep the file horizontal by detecting whether the file is in a horizontal state; such as the Chinese patents with publication numbers "CN113284398A", "CN203791752U", "CN203853629U", "CN215698490U", etc. Among them, the Chinese patent with publication number "CN113284398A" discloses "A Detection and Correction System for Fitter Filing Posture", and its horizontal detection requires a fitter's bench, a display screen, feedback software, etc. to complete the entire process of horizontal detection, resulting in a fixed use position of the file, and it must be used in combination with an operating table, and the structure is relatively complex; the Chinese patent with publication number "CN203791752U" discloses "Functional File Handle", which sets the horizontal detection device on the handle without a complex auxiliary structure; however, the level used in this solution is a mechanical level (bubble level), and the mechanical level will have a speed during the reciprocating movement of the file when processing the workpiece, resulting in a position deviation of the level due to its own inertia, further affecting the observation of the operator (including beginners and experienced users, hereinafter collectively referred to as the operator) and reducing the detection accuracy; moreover, the operator needs to observe the display of the mechanical level through the naked eye at all times. On the one hand, the judgment is subjective, and on the other hand, the operator also needs to observe the real-time state of the workpiece, so it is inconvenient for the operator to use. The Chinese patents with publication numbers "CN203791752U" and "CN215698490U" respectively disclose "A Horizontal Calibration File" and "A File with a Filing Correction Function", and their horizontal detection is set on the blade. As the part in contact with the workpiece, the position where the horizontal detection is set will affect the processing of the workpiece by the blade.

[0004] In summary, the current files with horizontal detection all have defects, such as complex structures, fixed usage locations, low accuracy of horizontal detection, inconvenience for operators to observe, and affecting the processing of workpieces by the file, etc. Summary of the Invention

[0005] The purpose of the present utility model is: aiming at the above problems, to provide a file handle and a file with an intelligent horizontal detection and alarm function, which have the advantages of simple file structure, not being restricted by the processing site, being convenient and not affecting the operator's observation on the premise of being able to remind the user to adjust the horizontal degree of the file.

[0006] The technical solution adopted by the present utility model is as follows: A file handle with an intelligent horizontal detection and alarm function, including a handle body with a connection part, and the connection part is used to connect with the tool body; the tool body has an installation cavity, and a horizontal detector and a controller are arranged in the installation cavity. The horizontal detector is used to detect the deviation direction and deviation degree from the reference plane; the horizontal detector is connected with the controller, and an alarm is connected to the output end of the controller. The alarm is fixed on the surface of the handle body and close to the connection part.

[0007] Further, a storage battery is also fixed in the installation cavity, and the storage battery is connected with the controller; or the controller is externally connected to a power supply.

[0008] Further, the handle body also has a cover for closing the installation cavity.

[0009] Further, the alarm is a sound alarm or a light alarm.

[0010] Further, a switch button is also arranged on the handle body, and the switch button is connected with the controller.

[0011] Further, the reference plane is the reference plane of the fixture, and a zeroing button is also arranged on the handle body for zeroing the reference plane. The reference plane is parallel to the reference surface, and the zeroing button is connected with the controller.

[0012] Further, the connection part has a connection structure for detachably connecting with the tool body.

[0013] Further, the connection structure is a threaded hole, and the axis of the threaded hole is parallel to the axis of the handle body; or the connection structure is a countersunk hole and a locking screw, the axis of the countersunk hole is parallel to the axis of the handle body, and the locking screw passes through the countersunk hole in a posture perpendicular to the axis of the countersunk hole and is threadedly connected with the handle body; or the connection structure is a wedge-shaped hole or a tapered hole, and the axis of the wedge-shaped hole or the tapered hole is parallel to the axis of the handle body.

[0014] A file, comprising a blade body and the file handle with the intelligent horizontal detection and alarm function, wherein the blade body is fixedly connected to the connecting part, and the axis of the blade body is parallel to the axis of the handle body.

[0015] Furthermore, the blade body is detachably connected to the handle body.

[0016] Furthermore, the blade body has an assembly structure matching the connection structure, and the assembly structure is detachably connected to the connection structure.

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] 1. By setting structures such as a horizontal detector and a controller in the present utility model, rather than a mechanical level (such as a bubble level) that requires direct observation, the position deviation of the level due to its own inertia is effectively avoided, that is, it will not affect the operator's observation and ensure the detection accuracy.

[0019] 2. By setting the horizontal detection on the handle body rather than the blade body in the present utility model, the horizontal detection is effectively prevented from affecting the processing of the workpiece by the blade body.

[0020] 3. By setting the alarm at a position close to the connecting part in the present utility model, for the operator holding the handle body, the alarm is in front of the hand, and the hand will not block the alarm, which is convenient for the operator to observe the alarm while using the file, enabling the operator to promptly know the state of the file and make corresponding responses.

[0032] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, if terms such as "set", "installed", "connected", "connected" are used, they should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0033] Embodiment 1

[0034] As Figures 1-6As shown in the figure, a file handle with an intelligent horizontal detection and alarm function includes a handle body 1 with a connecting part, and the connecting part is used to connect with the tool body 2; the tool body 2 has an installation cavity 11, and a horizontal detector 12 and a controller 13 are arranged in the installation cavity 11. The horizontal detector 12 is connected to the controller 13, and an alarm 15 is connected to the output end of the controller 13. The alarm 15 is fixed on the surface of the handle body 1 and close to the connecting part; specifically, the horizontal detector 12 can sense whether the handle body 1 is in a horizontal state, and send the sensed state to the controller 13. The controller 13 judges the state degree of the handle body 1. If it exceeds the set value, it controls the alarm 15 to give an alarm; the operator corrects the state of the handle body 1 in time according to the content of the alarm 15, so that the state degree of the handle body 1 is within the set value.

[0035] In this embodiment, the reference plane detected by the horizontal detector 12 can be a horizontal plane or the reference plane of the fixture; specifically, if the reference plane is a horizontal plane, when using the fixture to clamp the workpiece to be processed, it is necessary to ensure that the reference plane of the fixture is parallel to the horizontal plane; if the reference plane is the reference plane of the fixture, before using the handle body 1, it is necessary to place the handle body 1 on the reference plane of the fixture, and then set this plane as the reference plane of the horizontal detector 12 to ensure that the reference plane is parallel to the reference plane.

[0036] In this embodiment, the state degree is the angle deviating from the reference plane, that is, the included angle between the axis of the handle body 1 and the reference plane. The greater the state degree, the greater the deviating angle, and the greater the included angle between the axis and the reference plane; conversely, the smaller the state degree, the smaller the deviating angle, and the smaller the included angle between the axis and the reference plane; of course, the deviation is also divided into upward deviation and downward deviation, that is, relative to the reference plane, the deviation generated by the upward rotation of the axis is upward deviation, marked as "+"; the deviation generated by the downward rotation of the axis is downward deviation, marked as "-"; when there is upward deviation and downward deviation, the controller 13 can control the alarm 15 to generate different alarm information, so that the operator can know whether the handle body 1 is in an upward deviation or downward deviation state according to the corresponding alarm information, and thus quickly adjust the handle body 1 to a horizontal state.

[0037] In this embodiment, the horizontal detector 12 can be a three-dimensional angle sensor with the model number MPU 6050; the controller 13 can be a micro electrical control device such as STM32, PLC, or single-chip microcomputer; the control program is known to those skilled in the art and will not be described in detail here.

[0038] In this embodiment, the set value can be obtained through a limited number of tests and will not be described in detail in this specification; optionally, it is within -1.5° and +1.5°.

[0039] In this embodiment, by setting up structures such as the horizontal detector 12 and the controller 13, rather than directly observing a mechanical level (such as a bubble level), the position deviation of the level due to its own inertia is effectively avoided, that is, it will not affect the operator's observation and ensure the detection accuracy; by setting the horizontal detection on the tool holder body 1 instead of the tool body 2, the horizontal detection is effectively prevented from affecting the machining of the workpiece by the tool body 2; by setting the alarm 15 at a position close to the connection part, for the operator holding the tool holder body 1, the alarm 15 is in front of the hand, and the hand will not block the alarm 15, which is convenient for the operator to observe the alarm 15 while using the file, so that the operator can timely know the state of the file and make corresponding responses; without accessories such as a display screen, the horizontal detection has a small volume, and the use place of the file is not restricted.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, a feasible specific implementation manner is further proposed.

[0042] A feasible implementation manner is that a storage battery 16 is also fixed in the installation cavity 11, and the storage battery 16 is connected to the controller 13; or the controller 13 is externally connected to a power supply; both methods can enable the controller 13 to obtain continuous electric energy, so as to provide energy for continuously detecting the state of the tool holder body 1 by the horizontal detector 12.

[0043] A feasible implementation manner is that the tool holder body 1 also has a cover 14 for closing the installation cavity 11. The cover 14 protects components such as the storage battery 16, the horizontal detector 12, and the controller 13 in the installation cavity 11 from being damaged by the outside. Of course, for the implementation manner with the storage battery 16, the cover 14 and the tool holder body 1 can be detachably connected, just like the battery cover of a remote control, which is convenient for replacing the storage battery 16.

[0044] A feasible implementation manner is that the alarm 15 is a sound alarm 15, such as a horn, which directly gives a voice prompt to the operator for upward deviation or downward deviation and prompts the deviation angle; such as "upward deviation of 5°".

[0045] A feasible implementation manner is that the alarm 15 is a light alarm 15, such as an LED lamp; specifically, the alarm 15 includes two LED lamps that can generate different colors. When there is an upward deviation, the controller 13 controls one of the LED lamps to flash, and when there is a downward deviation, the controller 13 controls the other LED lamp to flash; the color of the light is used to determine whether the tool holder body 1 is in an upward deviation or a downward deviation, and the flashing frequency is used to judge the state degree, that is, the size of the deviation angle (such as when the deviation angle is large, the flashing frequency is fast); of course, the two LED lamps can also be combined into one LED lamp that can generate different colors.

[0046] It should be noted that the working place of the file is usually a processing place with relatively high noise. Therefore, the alarm generated by the alarm 15 of the sound alarm 15 is likely to be ignored. For this reason, the alarm 15 is preferably a lamp tube alarm 15.

[0047] In a feasible implementation manner, a switch button is further provided on the handle body 1. The switch button is connected to the controller 13, and the start of the horizontal detection is controlled through the switch button, so that the work can be stopped when the file is not in use.

[0048] In a feasible implementation manner, the base surface of the horizontal detector 12 is the reference surface of the fixture. The fixture is preferably a vise table; each time a workpiece is processed, in order to use the reference surface of the fixture as the base surface of the horizontal detector 12, a zeroing button can be provided on the handle body 1. The zeroing button is used to zero the base surface so that the base surface is parallel to the reference surface. The zeroing button is connected to the controller 13; specifically, each time a workpiece is processed, the handle body 1 is placed on the reference surface of the fixture so that the axis of the handle body is parallel to the reference surface of the fixture, and then the zeroing button is pressed. The control system uses the surface in this state as the base surface of the horizontal detector, that is, the base surface is parallel to the reference surface.

[0049] It should be noted that the zeroing button and the switch button can be two different buttons or combined into the same button; the specific program is known to those skilled in the art and will not be elaborated here.

[0050] Embodiment 3

[0051] On the basis of any one of the implementation manners in Embodiments 1-2, a feasible specific implementation manner is further proposed.

[0052] The connecting portion has a connecting structure for detachably connecting with the tool body 2, so that the tool body 2 and the handle can be replaced, and the handle can be applicable to tool bodies 2 of different specifications.

[0053] Specifically, the following two implementation manners are proposed for the connecting structure.

[0054] In the first implementation manner, the connecting structure is a threaded hole 17, and the axis of the threaded hole 17 is parallel to the axis of the handle body 1; the handle body 1 and the tool body 2 are detachably connected through the threaded hole 17.

[0055] In the second implementation mode, the connection structure is a countersunk hole 18 and a locking screw 19. The axis of the countersunk hole 18 is parallel to the axis of the tool holder body 1, and the locking screw 19 passes through the countersunk hole 18 in a posture perpendicular to the axis of the countersunk hole 18 and is threadedly connected to the tool holder body 1. After the tool body 2 is inserted into the countersunk hole 18, the tool body 2 is locked by the locking screw 19, thereby realizing the detachable connection between the tool holder body 1 and the tool body 2; the threaded connection between the locking screw 19 and the tool holder body 1 can effectively prevent the locking screw 19 from loosening and ensure the stability of locking the tool body 2.

[0056] It should be noted that in the first implementation mode and the second implementation mode, the design of the axis of the threaded hole 17 or the countersunk hole 18 is to ensure that after the tool body 2 is connected to the tool holder body 1, the axis of the tool body 2 is parallel to the axis of the tool holder body 1, preferably collinear, so as to ensure that the horizontal state of the tool body 2 is consistent with the horizontal state of the tool holder body 1.

[0057] In the third implementation mode, the connection structure is a wedge-shaped hole 3. The axis of the wedge-shaped hole 3 is parallel to the axis of the tool holder body to ensure that the surface of the file is parallel to the surface of the tool holder body after being connected to the tool body 2; there is a wedge-shaped block 24 matching the wedge-shaped hole 3 at the position where the tool body 2 is connected to the tool holder body 1; when the wedge-shaped block 24 is inserted into the wedge-shaped hole 3, during each push of the file when processing a workpiece, the resistance received by the tool body 2 causes the wedge-shaped block 24 to be inserted deeper and deeper into the wedge-shaped hole 3, so that the connection between the tool body 2 and the tool holder body 1 becomes more and more stable.

[0058] In the fourth implementation mode, the connection structure is a tapered hole 4. The axis of the tapered hole 4 is parallel to the axis of the tool holder body to ensure that the surface of the file is parallel to the surface of the tool holder body after being connected to the tool body 2; there is a tapered portion 25 matching the wedge-shaped hole 3 at the position where the tool body 2 is connected to the tool holder body 1; the principle of connection between the tapered hole 4 and the tapered portion 25 is the same as that of the third implementation mode and will not be elaborated here.

[0059] It should be noted that in the third and fourth implementation modes, the file does not contact the workpiece when being pulled back, so the tool body 2 in the file will not be separated from the tool holder body 1 during workpiece processing.

[0060] It should be noted that in the third and fourth implementation modes, when disassembling the tool body 1, only gently tap the tool body 1 to loosen the connection between the tool body 1 and the tool holder body 2.

[0061] It should be noted that compared with the fourth implementation mode, the third implementation mode can perform circumferential positioning and will not rotate; therefore, the third implementation mode is preferably selected.

[0062] Example 4

[0063] A file, comprising a tool body 2 and a file handle with an intelligent horizontal detection and alarm function described in any one of Embodiments 1-3. The tool body 2 is fixedly connected to the connecting portion, and this fixed connection can be a detachable fixed connection or a non-detachable fixed connection. The axis of the tool body 2 is parallel to the axis of the handle body 1, preferably collinear, to ensure that the horizontal state of the tool body 2 is consistent with the horizontal state of the handle body 1.

[0064] Embodiment 5

[0065] On the basis of Embodiment 4, a feasible specific implementation manner is further proposed.

[0066] The tool body 2 is detachably connected to the handle body 1, so that the tool body 2 and the handle can be replaced, and the handle can be applicable to tool bodies 2 of different specifications.

[0067] Specifically, the tool body 2 has an assembly structure matching the connection structure, and the assembly structure is detachably connected to the connection structure, so as to realize the detachable connection between the tool body 2 and the handle body 1. Specifically, as Figure 3 shown, for the first implementation manner in Embodiment 3, the assembly structure can be a screw 21 coaxial with the tool body 2, and the screw 21 is threadedly connected to the threaded hole 17; as Figure 4 shown, for the second implementation manner in Embodiment 3, the assembly structure can be an insertion pin 22 coaxial with the tool body 2. The size of the insertion pin 22 matches the size of the counterbore 18, and a locking hole 23 for inserting the locking screw 19 is provided at the position corresponding to the locking screw 19 on the insertion pin 22. The circumferential and axial locking of the insertion pin 22 is realized by inserting the locking screw 19 into the locking hole 23; as Figure 5 shown, for the third implementation manner in Embodiment 3, the assembly structure is a wedge block 24; as Figure 6 described, for the fourth implementation manner in Embodiment 3, the assembly structure is a tapered portion 25.

[0068] The present utility model is not limited to the foregoing specific implementation manners. The present utility model extends to any new feature or any new combination disclosed in this specification, and any new method or process step or any new combination disclosed.
