When a tool with an electronic tag is installed in the corresponding drill handle, the recognition coil can read the tool information in the electronic tag and then transmit the tool information to the host, realizing automatic tool recognition.

[0003] However, traditional drill handles often have problems with tool recognition after the tool is loaded, which affects the normal use of the handle. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a drill handle and a drill grinding device to solve the problem of poor tool recognition after the tool is loaded into the drill handle in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a drill handle adapted to a cutting tool, the drill handle comprising:

[0006] Handle housing;

[0007] A power output assembly is disposed within the handle housing, the power output assembly having a mounting channel for inserting a cutting tool, the power output assembly being used to drive the cutting tool inserted into the mounting channel;

[0008] A tool identification component is disposed within the handle housing, the tool identification component having a hollow identification channel coaxially connected to the front end of the mounting channel;

[0009] When the cutting tool is inserted into the installation channel through the hollow identification channel, the electronic tag on the cutting tool is correspondingly placed in the hollow identification channel so that the cutting tool identification component can identify the electronic tag in the hollow identification channel.

[0013] Optionally, the coil sleeve is a non-metallic, non-magnetic coil sleeve.

[0014] Optionally, the coil sleeve includes a coil mounting section extending along the axial direction of the hollow identification channel. When the cutter is inserted into the mounting channel through the hollow identification channel, the electronic tag is positioned in the hollow identification channel at a position corresponding to the coil mounting section.

[0015] Optionally, the power output assembly includes an output shaft, and the mounting channel is formed on the output shaft and extends along the axial direction of the output shaft.

[0016] Optionally, the power output assembly further includes a mounting sleeve that is relatively fixedly disposed within the handle housing, the output shaft being rotatably disposed within the mounting sleeve along its own axis, the coil sleeve being directly or indirectly connected to the mounting sleeve, and the coil sleeve having an axial clearance greater than zero between the output shaft and the output shaft.

[0017] Optionally, the mounting sleeve has a connecting portion extending forward beyond the mounting channel, and the coil sleeve extends relatively fixedly into the connecting portion.

[0018] Optionally, the tool identification component further includes a mating sleeve for connecting the coil sleeve to the mounting sleeve, and / or, an anti-rotation structure is provided between the inner wall of the connecting part and the outer wall of the rear end of the coil sleeve; and / or, the inner wall of the connecting part is provided with a first protrusion, the outer wall of the coil sleeve is provided with a second protrusion, and the mounting sleeve abuts the first protrusion and the second protrusion along the axial direction.

[0019] Optionally, the handle housing is provided with a mounting structure for mounting and positioning the tool identification component, and the power output component and the tool identification component have an axial clearance greater than zero.

[0022] This utility model also provides a grinding device, which includes a matching cutting tool and a grinding handle, wherein the grinding handle is the grinding handle as described above.

[0023] As described above, in the drill handle of this invention, both the power output component and the tool identification component are housed within the handle housing. The power output component has an installation channel for inserting the tool, and the tool identification component has a hollow identification channel coaxially connected to the front end of the installation channel. In other words, the tool identification component is located at the front end of the installation channel. An electronic tag on the tool is correspondingly positioned within the hollow identification channel, allowing the tool identification component and the electronic tag on the tool to be correspondingly positioned and mutually compatible. Both the tool identification component and the electronic tag on the tool are axially offset from the installation channel, ensuring that when the tool is inserted into the installation channel via the hollow identification channel, the tool identification component and the electronic tag do not obstruct each other radially. This avoids interference with the tool identification function caused by the power output component during the operation of the drill handle, thus preventing problems with tool identification after tool insertion.

[0032] After the drill handle is fitted with the tool 4, there are often metal parts between the identification coil 32 inside the drill handle and the tool 4. These metal parts are usually components of the power output assembly 2, designed to provide power output. This causes the identification coil 32 to easily detect interference from these metal parts when reading the electronic tag 41 on the tool 4, leading to identification problems and affecting the normal use of the handle. The following embodiments aim to solve the problem of identification problems caused by interference from these metal parts.

[0033] In the description of the following embodiments, "axial direction" refers to the axial direction of the handle housing 1, which is also the axial direction of the entire drill handle; in the description of the following embodiments, the directional terms "front" and "back" are relative directions, "front" refers to the direction of the drill bit that is closer to the tool 4 along the axial direction, and "back" refers to the direction of the drill bit that is farther away from the tool 4 along the axial direction.

[0034] Please see Figure 1 This embodiment provides a drill handle that is adapted to the tool 4. The drill handle includes:

[0035] Handle housing 1;

[0036] The power output assembly 2 is disposed inside the handle housing 1. The power output assembly 2 has a mounting channel 211 for inserting the tool 4. The power output assembly 2 is used to drive the tool 4 inserted into the mounting channel 211.

[0037] The tool recognition component 3 is disposed inside the handle housing 1. The tool recognition component 3 has a hollow recognition channel 311 coaxially connected to the front end of the mounting channel 211.

[0038] When the cutting tool 4 is inserted into the installation channel 211 through the hollow identification channel 311, the electronic tag 41 on the cutting tool 4 is correspondingly placed in the hollow identification channel 311 so that the cutting tool identification component 3 can identify the electronic tag 41 in the hollow identification channel 311.

[0039] The aforementioned "handle housing 1" can refer to the outermost part of the entire handle that may directly contact the operator. Specifically, the handle housing 1 can be a single part or it can be constructed from multiple parts. When the handle housing 1 is composed of multiple parts, the components in the handle housing 1 can be relatively fixed, and there can also be parts in the handle housing 1 that can move or rotate relative to other parts in the handle housing 1.

[0040] Figure 1 In this embodiment, the handle housing 1 has an inner cavity that extends axially. The front end of the inner cavity is open, and the rear end is closed. Both the power output assembly 2 and the tool identification assembly 3 are disposed within the inner cavity of the handle housing 1. The power output assembly 2 has a mounting channel 211 for inserting a tool 4, which extends axially along the handle housing 1. The tool 4 is coaxially arranged with the handle housing 1, and its rear end extends into the mounting channel 211 and is connected to the power output assembly 2 via a transmission connection. The power output assembly 2 can drive the tool 4 to rotate within the handle housing 1 along its own axis.

[0041] In this embodiment, the tool identification component 3 has a hollow identification channel 311 coaxially connected to the front end of the mounting channel 211. This indicates that the tool identification component 3 and the mounting channel 211 are offset in the axial direction, and the tool identification component 3 is located at the front end of the mounting channel 211. Furthermore, when the tool 4 is inserted into the mounting channel 211 via the hollow identification channel 311, the electronic tag 41 on the tool 4 is correspondingly positioned within the hollow identification channel 311. This allows the tool identification component 3 and the electronic tag 41 on the tool 4 to be correspondingly positioned, and there is no radial obstruction between the tool identification component 3 and the electronic tag 41. Therefore, the identification of the electronic tag 41 by the tool identification component 3 is not affected by other components.

[0042] In this embodiment, both the power output component 2 and the tool identification component 3 are housed within the handle housing 1. The power output component 2 has an installation channel 211 for inserting the tool 4, and the tool identification component 3 has a hollow identification channel 311 coaxially connected to the front end of the installation channel 211. In other words, the tool identification component 3 is located at the front end of the installation channel 211. The electronic tag 41 on the tool 4 is correspondingly positioned within the hollow identification channel 311, allowing the tool identification component 3 and the electronic tag 41 on the tool 4 to be correspondingly positioned and cooperate with each other. Both the tool identification component 3 and the electronic tag 41 on the tool 4 are axially offset from the installation channel 211, ensuring that when the tool 4 is inserted into the installation channel 211 via the hollow identification channel 311, the tool identification component 3 and the electronic tag 41 do not obstruct each other radially. This avoids interference from other components during the operation of the drill handle with the tool identification function, thus preventing problems with tool identification after tool 4 is inserted.

[0043] In one implementation, such as Figure 1 and Figure 4 As shown, the tool recognition component 3 includes:

[0044] A coil sleeve 31 is disposed inside the handle housing 1, and the hollow channel of the coil sleeve 31 forms a hollow recognition channel 311;

[0045] Identification coil 32 is wound around the outer wall of coil sleeve 31.

[0046] Specifically, the coil sleeve 31 is open at both ends along the axial direction, forming a hollow identification channel 311 between the two open ends along the axial direction. The identification coil 32 is spirally wound on the outer wall of the coil sleeve 31 and arranged along the axial direction of the outer wall of the coil sleeve 31. The identification coil 32 can cooperate with the electronic tag 41 on the tool 4 to obtain the tool 4 information in the electronic tag 41. A cable electrically connected to the identification coil 32 is provided in the handle housing 1, and the tool 4 information is transmitted to the host through the cable. After the host identifies the inserted tool 4, it can control the grinding handle to work according to the tool information. For example, it can automatically match the most suitable motor output speed for the inserted tool 4, reducing the need for manual parameter setting by the user. The identification coil 32 and the electronic tag 41 are separated only by the coil sleeve 31, making the distance between the identification coil 32 and the electronic tag 41 small, which helps to ensure the identification effect of the identification coil 32 on the tool 4 information in the electronic tag 41.

[0047] In one embodiment, the coil sleeve 31 is a non-metallic, non-magnetic coil sleeve 31, meaning that the material of the coil sleeve 31 can be any non-metallic, non-magnetic material disclosed in the prior art, such as ceramics, synthetic rubber, synthetic resin (plastic), synthetic fibers, etc. The coil sleeve 31 is positioned between the identification coil 32 and the electronic tag 41. The non-metallic, non-magnetic coil sleeve 31 can avoid interfering with the identification process between the identification coil 32 and the electronic tag 41, which helps to ensure the identification effect of the tool 4.

[0048] In one implementation, such as Figure 1 and Figure 3 As shown, the coil sleeve 31 includes a coil mounting section extending along the axial direction of the hollow identification channel 311. When the tool 4 is inserted into the mounting channel 211 through the hollow identification channel 311, the electronic tag 41 is positioned in the hollow identification channel 311 at a position corresponding to the coil mounting section.

[0049] The identification coil 32 is wound around the coil mounting section and arranged axially on the coil mounting section. When the tool 4 is installed in the handle housing 1, the electronic tag 41 and the identification coil 32 are correspondingly set in the axial direction, reducing the distance between the electronic tag 41 and the identification coil 32 in the axial direction, which helps to ensure the identification effect of the tool 4.

[0050] The aforementioned "power output assembly 2 having a mounting channel 211 for inserting the tool 4" can be implemented in several possible ways: in one embodiment, such as Figure 1 and Figure 3 As shown, the power output assembly 2 includes an output shaft 21, and a mounting channel 211 is formed on the output shaft 21 and extends along the axial direction of the output shaft 21.

[0051] The output shaft 21 has an open front end, which extends rearward along the axial direction to form a mounting channel 211. The output shaft 21 is typically made of metal, which can interfere with the identification between the identification coil 32 and the electronic tag 41. By axially offsetting the coil sleeve 31 from the output shaft 21, the identification coil 32 is also axially offset from the output shaft 21. This avoids interference from the output shaft 21 with the identification between the identification coil 32 and the electronic tag 41, thus ensuring the identification effect of the tool 4.

[0052] In another possible implementation (not shown in the figure), the mounting channel 211 is formed on other components of the power output assembly 2, rather than on the output shaft 21. For example, the mounting channel 211 can be formed at the front end of the output shaft 21, and the tool 4 is inserted into the mounting channel 211 and connected to the front end of the output shaft 21 by means of a coupling or the like.

[0053] In some implementations, see Figure 1 and Figure 3 The power output assembly 2 also includes a mounting sleeve 22 that is relatively fixedly disposed within the handle housing 1. The output shaft 21 is rotatably disposed within the mounting sleeve 22 along its own axis. The coil sleeve 31 is directly or indirectly connected to the mounting sleeve 22. There is a greater than zero axial clearance between the coil sleeve 31 and the output shaft 21. In this way, by fixing the coil sleeve 31, it is possible to prevent it from moving in the axial direction and rotating along its own axis. On the one hand, this can prevent the tool 4 from failing to be identified due to the coil sleeve 31 moving beyond the effective identification range with the electronic tag 41. On the other hand, it can also prevent the identification coil 32 and the cable from getting tangled, which would affect the normal use of the drill handle.

[0054] The following embodiments will describe how to achieve a "direct or indirect connection between the coil sleeve 31 and the mounting sleeve connection 22":

[0055] Optionally, the mounting sleeve 22 has a connecting portion 221 that extends forward beyond the mounting channel 211, and the coil sleeve 31 extends relatively fixedly into the connecting portion 221.

[0056] like Figure 1 and Figure 3 In the illustrated embodiment, an anti-rotation structure is also provided between the connecting portion 221 and the rear outer wall of the coil sleeve 31. For example, the rear outer wall of the coil sleeve can be partially planar, forming a flat portion 312. An anti-rotation portion that cooperates with the flat portion 312 is provided on the inner wall of the connecting portion 221, which can limit the radial direction of the coil sleeve 31 and prevent it from rotating. Of course, this anti-rotation structure can be constructed by key and keyway cooperation or other methods.

[0057] Figures 1 to 3 In one embodiment, at least one set of first protrusions on the inner wall of the connecting portion 221, and a second protrusion on the inner wall of the coil sleeve 221, the rear end face of the second protrusion abuts against the front end face of the coil sleeve 31, limiting the rear end of the coil sleeve 31 and preventing the coil sleeve 31 from moving backward in the axial direction. Furthermore, Figures 1 to 3 In one embodiment, the anti-rotation part is formed on the first protrusion, so that the anti-rotation part and the axis limiting structure are both integrated on the first protrusion, resulting in a simple and compact structure. Figures 1 to 3 In one embodiment, the second protrusion is located at the front end of the anti-rotation part. In one possible implementation, the rear end of the coil sleeve 31 is directly fixedly connected to the connecting part 221.

[0058] Specifically, two retaining rings (not shown in the figures) arranged in the axial direction can be fitted inside the connecting part 221. The two retaining rings abut against the front end face and the rear end face of the coil sleeve 31 respectively, so as to limit the coil sleeve 31 in the axial direction and the radial direction.

[0059] In another possible implementation, such as Figures 1 to 3 As shown, the tool identification component 3 also includes a docking sleeve 33, which is used to connect the coil sleeve 31 to the mounting sleeve 22.

[0060] Specifically, the rear threaded connection of the mating sleeve 33 and the positioning of the retaining ring are detachably fitted onto the front outer wall of the mounting sleeve 22. A step 331 is provided on the front inner wall of the mating sleeve 33. The step 331 abuts against the front end face of the coil sleeve 31 to prevent the coil sleeve 31 from moving forward in the axial direction. The first protrusion and the step 331 work together to limit the coil sleeve 31 in the axial direction.

[0061] In one implementation, such as Figure 2 As shown, the mounting sleeve 22 and the mating sleeve 33 can be connected by a claw structure. The outer wall of the mounting sleeve 22 is provided with a first claw 221a extending forward and facing upward, and the outer wall of the mating sleeve 33 is provided with a second claw 332 extending backward and facing downward. Through the mutual engagement of the first claw 221a and the second claw 332, the mounting sleeve 22 and the mating sleeve 33 are locked together axially.

[0062] Optionally, the outer wall of the mating sleeve 33 is provided with a first claw groove, and the outer wall of the mounting sleeve 22 is provided with a second claw groove (the first and second claw grooves are not shown in the figure). The first claw 221a is engaged in the first claw groove, and the second claw 332 is engaged in the second claw groove, so as to lock the mating sleeve 33 and the mounting sleeve 22 in the axial and radial directions.

[0063] Figures 1 to 3 In one embodiment, the tool identification component 3 is directly mounted on the mounting sleeve 22 on the power output component 2. In another embodiment, a mounting structure for mounting and positioning the tool identification component 3 can also be directly provided in the handle housing 1, and the power output component 2 and the tool identification component 3 have an axial clearance greater than zero.

[0064] In this way, the power output component 2 and the tool identification component 3 can be completely offset in the axial direction, so that the tool identification component 3 can be far away from the power output component 2, which helps to further reduce the impact of the power output component 2 on the tool identification function of the tool 4.

[0065] In one embodiment, the front end of the drill handle is detachably connected to a support attachment 5, which has a support channel.

[0066] When the support accessory 5 is installed at the front end of the handle housing 1, the support channel is coaxially connected to the front end of the hollow recognition channel 311.

[0067] The support accessory 5 is coaxially and detachably mounted at the front end of the handle housing 1, and the support channel of the support accessory 5 is coaxially connected with the hollow identification channel 311.

[0068] For ease of understanding, see [link to relevant documentation]. Figure 3 The support attachment 5 is connected to the front end of the mounting sleeve 22.

[0069] This embodiment also provides a grinding device, which includes a cutting tool 4 and a grinding handle as described above. The cutting tool 4 is axially locked to the power output assembly 2. The power output assembly 2 and the cutting tool 4 are connected in a transmission manner and provide rotational power to the cutting tool 4.

[0070] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
