Abstract

A rotation lock mechanism includes a spindle, a base, a rotation ring and a limiting mechanism. The base includes a channel. The spindle is disposed through the channel and is rotatable in the channel. The rotation ring is rotatably disposed on the base. The limiting mechanism is moveably disposed between the base and the rotation ring. When the rotation ring is rotated toward a first direction, the rotation ring links the limiting mechanism to move from an initial position and withstand the spindle, thereby making the spindle unable to rotate. When the rotation ring is rotated toward a second direction, the limiting mechanism is moved back to the initial position and doesn’t withstand the spindle, and the spindle can be freely rotated. Therefore, the rotation of the spindle can be easily locked by the rotation ring, and a socket or an adapter assemble with the spindle can be easily dismantled and replaced.

Description

動力工具及轉動鎖定機構 Power tool and rotation locking mechanism

本創作係關於一種鎖定機構；更具體言之，本創作係關於一種可用於動力工具之轉動鎖定機構。 This creation is about a locking mechanism; more specifically, this creation is about a rotation locking mechanism that can be used for power tools.

動力工具諸如電鑽或電錘等已為日常生或中所常用者。通常此種動力工具具有驅動機構、與驅動機構耦合的驅動馬達以及由驅動機構帶動而可轉動產生轉矩之主軸(Spindle)。通常主軸還裝配有可由其驅動的工具轉接件以及於動力工具內裝配有主軸鎖定機構。 Power tools such as electric drills or electric hammers have been used in daily life. Generally, this kind of power tool has a driving mechanism, a driving motor coupled with the driving mechanism, and a spindle driven by the driving mechanism to rotate and generate torque. Usually the spindle is also equipped with a tool adapter that can be driven by it and a spindle locking mechanism is installed in the power tool.

主軸鎖定機構在一些情況下可鎖定主軸使其不轉動。為協助操作者安裝或更換新的工具轉接件，當驅動馬達及驅動機構不運轉，操作者向主軸施力以卸除工具轉接件時，倘若無裝置此種主軸鎖定機構，則此種施力往往會使主軸與工具轉接件同步旋轉而使工具轉接件拆卸不易。此外，此種施力往往令主軸於驅動機構及馬達不運轉時產生不當轉動，進而損壞與主軸連動之相關零組件。 The spindle locking mechanism can lock the spindle from rotation in some cases. In order to assist the operator in installing or replacing a new tool adapter, when the drive motor and drive mechanism are not running and the operator applies force to the spindle to remove the tool adapter, if there is no such spindle locking mechanism, this Applying force often causes the spindle and the tool adapter to rotate synchronously, making it difficult to disassemble the tool adapter. In addition, this kind of force often causes the main shaft to rotate improperly when the drive mechanism and the motor are not running, thereby damaging related components linked to the main shaft.

主軸鎖定機構具有多種類型。一種主軸鎖定機構包含多個滾軸，當操作者施力時，滾軸可被壓入與對應的連接部分接合，以防止主軸轉動。另一種主軸鎖定機構包含相互嚙合的齒件，例如固定的內齒輪以及承載在主軸上可活動的齒件，齒件與主軸同步旋轉，並相對主軸移動至鎖定位置，齒件可於鎖定位置中嚙合以防止主軸轉動。 There are many types of spindle locking mechanisms. Spindle locking machine The structure includes a plurality of rollers, when the operator applies force, the rollers can be pressed into and engaged with the corresponding connecting parts to prevent the main shaft from rotating. Another spindle locking mechanism includes gears that mesh with each other, such as a fixed internal gear and a movable gear carried on the spindle. The gear rotates synchronously with the spindle and moves to the locked position relative to the spindle, and the gear can be in the locked position Engage to prevent the spindle from rotating.

上述主軸鎖定機構仍存有問題，當驅動馬達停止運轉時，主軸仍然因慣性而持續轉動一段時間。此時，由於上述主軸鎖定機構皆因使用嚙合之組件而鎖定主軸之轉動，因此用於鎖定主軸之零組件可能因主軸之轉動而產生衝擊，進而產生異常高之聲響或零組件損壞。並且，其用於嚙合之零組件結構過於複雜，致使其製造成本高。因此，開發製造成本低、具高的使用便利性及靈活性、且可避免零組件損壞之產品仍有所必要。 The above-mentioned spindle locking mechanism still has a problem. When the driving motor stops, the spindle continues to rotate for a period of time due to inertia. At this time, since the above-mentioned spindle locking mechanism locks the rotation of the spindle due to the use of meshing components, the components used to lock the spindle may be impacted by the rotation of the spindle, resulting in abnormally loud noise or component damage. In addition, the structure of the components used for meshing is too complicated, resulting in high manufacturing costs. Therefore, it is still necessary to develop products that are low in manufacturing cost, have high convenience and flexibility, and can avoid component damage.

本創作係提供一種可用於動力工具的轉動鎖定機構。其係藉由轉環向不同方向轉動，以控制限制機構的位移，進而令主軸可被鎖定無法轉動或自由轉動。藉此，透過簡易的方式鎖定主軸的轉動，利於單手操作動力工具及更換不同配合主軸使用的套筒或轉接件，具使用上便利性及靈活性。並且可避免主軸不當轉動造成機構損壞。 This creative department provides a rotation locking mechanism that can be used for power tools. It uses the rotating ring to rotate in different directions to control the displacement of the restriction mechanism, so that the spindle can be locked and cannot rotate or rotate freely. In this way, the rotation of the main shaft can be locked in a simple manner, which facilitates one-handed operation of power tools and replacement of sleeves or adapters used with different main shafts, which is convenient and flexible in use. In addition, damage to the mechanism caused by improper rotation of the spindle can be avoided.

以下將參照圖式說明本創作之複數個實施例。為明確說明起見，許多實務上的細節將在以下敘述中一併說明。然而，應瞭解到，這些實務上的細節不應用以限制本創作。也就是說，在本創作部分實施例中，這些實務上的細節是非必要的。此外，為簡化圖式及著重於本創作主要技術特徵，一些習知慣用、非必要的結構與元件，將在圖式中以簡單示意的方式繪示或省略之。 Hereinafter, a plurality of embodiments of this creation will be described with reference to the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details should not be used to limit this creation. In other words, in the embodiments of this authoring part, these practical details are unnecessary. In addition, in order to simplify the schema and focus on the main technical features of this creation Characters, some conventional and non-essential structures and elements will be shown in the drawings in a simple way or omitted.

請參照第1圖及第2圖。第1圖係繪示依據本創作一實施例之轉動鎖定機構之結構示意圖。第2圖係繪示依據本創作一實施例之動力工具之結構分解示意圖。轉動鎖定機構包含一主軸111、一基座112、一轉環113以及一限制機構117。基座112包含一中空通道114，主軸111穿設過中空通道114而可於中空通道114內轉動。轉環113可轉動地套設於基座112上。限制機構117可位移地組設於基座112及轉環113之間。當轉環113向一第一方向轉動時，轉環113帶動限制機構117自一初始位置形成位移而抵頂主軸111，令主軸111無法轉動。當轉環113向一第二方向轉動時，限制機構117復位至初始位置而不抵頂主軸111，此時主軸111可自由轉動。 Please refer to Figure 1 and Figure 2. Figure 1 is a schematic diagram showing the structure of a rotation locking mechanism according to an embodiment of the invention. Figure 2 is an exploded schematic diagram showing the structure of the power tool according to an embodiment of the invention. The rotation locking mechanism includes a spindle 111, a base 112, a rotating ring 113, and a restricting mechanism 117. The base 112 includes a hollow channel 114, and the main shaft 111 passes through the hollow channel 114 and can rotate in the hollow channel 114. The rotating ring 113 is rotatably sleeved on the base 112. The restriction mechanism 117 is displaceably assembled between the base 112 and the rotating ring 113. When the rotating ring 113 rotates in a first direction, the rotating ring 113 drives the restricting mechanism 117 to move from an initial position to abut the main shaft 111, so that the main shaft 111 cannot rotate. When the rotating ring 113 rotates in a second direction, the restriction mechanism 117 is reset to the initial position and does not abut the main shaft 111, and the main shaft 111 can rotate freely at this time.

進一步而言，基座112包含一滑槽115，轉環113環繞滑槽115而可繞滑槽115轉動。限制機構117包含至少一復位件117a以及至少一制動件117b。滑槽115上開設一開孔116，復位件117a組設於開孔116內，制動件117b則穿設過復位件117a而可於開孔116內位移。當制動件117b位移時，復位件117a可被壓縮而蓄積一彈性恢復力。復位件117a及制動件117b之數量可變。例如本實施例中，使用二復位件117a及二制動件117b分別組設於滑槽115之二相對位置之二開孔116內。各復位件117a可使用一壓縮彈簧，惟不以此為限。 Furthermore, the base 112 includes a sliding groove 115, and the rotating ring 113 surrounds the sliding groove 115 and can rotate around the sliding groove 115. The restriction mechanism 117 includes at least one restoring element 117a and at least one braking element 117b. An opening 116 is defined in the sliding groove 115, the restoring member 117 a is assembled in the opening 116, and the braking member 117 b passes through the restoring member 117 a and can be displaced in the opening 116. When the braking member 117b is displaced, the restoring member 117a can be compressed to accumulate an elastic restoring force. The number of the reset member 117a and the brake member 117b is variable. For example, in this embodiment, two restoring elements 117a and two braking elements 117b are used to be respectively assembled in the two openings 116 of the two relative positions of the sliding groove 115. Each return piece 117a can use a compression spring, but it is not limited thereto.

為形成對主軸111轉動之鎖定或釋放，轉環113之內側包含至少一凸點118。凸點118之數量可配合制動件117b之數量而設置，本實施例中，配合二制動件117b設置二凸點118。當轉環113向第一方向轉動時，凸點118抵頂制動件117b，令制動件117b自初始位置形成位移壓縮復位件117a而蓄積彈性恢復力。當轉環113向第二方向轉動時，凸點118不抵頂制動件117b，制動件117b為復位件117a之彈性恢復力推動而復位至初始位置。 In order to lock or release the rotation of the main shaft 111, the inner side of the rotating ring 113 includes at least one convex point 118. The number of the bumps 118 can be set according to the number of the stoppers 117b. In this embodiment, two bumps 118 are provided in conjunction with the two stoppers 117b. When the swivel 113 rotates in the first direction, the bump 118 abuts the stopper 117b, causing the stopper 117b to form a displacement compression resetting member 117a from the initial position to accumulate elastic restoring force. When the swivel 113 rotates in the second direction, the convex point 118 does not abut the stopper 117b, and the stopper 117b is pushed by the elastic restoring force of the return element 117a to return to the initial position.

主軸111則包含至少一止動面119，本實施例中，主軸111包含四個止動面119，該四個止動面1119二二對稱，並隨主軸111轉動而轉動。當轉環113向第一方向轉動時，二制動件117b各自受轉環113之二凸點118推動而各自自初始位置形成位移，進而抵頂二止動面119，令主軸111被鎖定無法轉動，並令各復位件117a被壓縮而蓄積彈性恢復力。當轉環113向第二方向轉動時，轉環113之二凸點118各自遠離各二制動件117b，二制動件117b為各復位件117a之彈性恢復力推動而復位至初始位置，因此止動面119不受制動件117b抵頂，因此主軸111被釋放而可自由轉動。 The main shaft 111 includes at least one stop surface 119. In this embodiment, the main shaft 111 includes four stop surfaces 119. The four stop surfaces 1119 are two-by-two symmetrical and rotate as the main shaft 111 rotates. When the swivel 113 rotates in the first direction, the two stoppers 117b are each pushed by the two convex points 118 of the swivel 113 to form a displacement from the initial position, and then press against the two stop surfaces 119, so that the spindle 111 is locked and cannot be rotated. , And make each return piece 117a be compressed to accumulate elastic restoring force. When the swivel 113 rotates in the second direction, the two convex points 118 of the swivel 113 are respectively far away from the two stoppers 117b. The two stoppers 117b are pushed by the elastic restoring force of the resetting members 117a to reset to the initial position, thus stopping The surface 119 is not pressed by the stopper 117b, so the spindle 111 is released and can rotate freely.

滑槽115之一側設有一限位件120，滑槽115之另一側設有一***121。限位件120配合***121以於轉環113轉動至一預設位置時限位並固定轉環113。藉此，可準確令轉環113轉動至正確位置並被固定，避免轉環113不穩定轉動而致無法有效鎖定或釋放主軸111。 One side of the sliding groove 115 is provided with a limiting member 120, and the other side of the sliding groove 115 is provided with a positioner 121. The limiting member 120 cooperates with the positioner 121 to limit and fix the rotating ring 113 when the rotating ring 113 rotates to a predetermined position. In this way, the rotating ring 113 can be accurately rotated to the correct position and fixed, and the rotating ring 113 can be prevented from turning unstable. As a result, the spindle 111 cannot be effectively locked or released.

當組設成一動力工具時，如第2圖所繪示，動力工具之本體122內包含一驅動機構123。轉動鎖定機構則與本體122組設。驅動機構123包含一轉子124及一齒輪125。齒輪125與主軸111耦合，轉子124帶動齒輪125轉動，進而帶動主軸111轉動。一實施例中，於本體122內設置氣動馬達或電動馬達以驅動轉子124旋轉，藉此可帶動主軸111轉動。主軸111之一端可包含一夾具部126，夾具部126可供一套筒127或一轉接件組設。藉此透過主軸111的轉動而可施行各式作業。 When assembled as a power tool, as shown in FIG. 2, the body 122 of the power tool includes a driving mechanism 123. The rotation locking mechanism is assembled with the main body 122. The driving mechanism 123 includes a rotor 124 and a gear 125. The gear 125 is coupled with the main shaft 111, and the rotor 124 drives the gear 125 to rotate, which in turn drives the main shaft 111 to rotate. In one embodiment, an air motor or an electric motor is provided in the main body 122 to drive the rotor 124 to rotate, thereby driving the main shaft 111 to rotate. One end of the main shaft 111 may include a clamp portion 126, and the clamp portion 126 can be assembled with a sleeve 127 or an adapter. Therefore, various operations can be performed through the rotation of the main shaft 111.

請一併參照第3圖至第6圖。第3圖係繪示本創作之轉動鎖定機構操作於第一狀態之示意圖。第4圖係繪第3圖之轉動鎖定機構之部分零件剖視圖。第5圖係繪示本創作之轉動鎖定機構操作於第二狀態之示意圖。第6圖係繪示第5圖之轉動鎖定機構之部分零件剖視圖。第3及第4圖中，轉動鎖定機構係於第一狀態，亦即主軸111被鎖定而無法轉動之狀態。此時，轉環113向第一方向轉動，二制動件117b各自受轉環113之二凸點118推動而各自自初始位置形成位移，進而抵頂二止動面119，令主軸111被鎖定無法轉動，並令各復位件117a被壓縮而蓄積彈性恢復力。第5圖及第6圖中，轉動鎖定機構係於第二狀態，亦即主軸111被釋放而可自由轉動之狀態。此時，轉環113向第二方向轉動，轉環113之二凸點118各自遠離各二制動件117b而不再推動二制動件117b，二制動件117b為各復位件117a之彈性恢復力推動而復位至初始位置，因此止動面119不受制動件117b抵頂，主軸111因此被釋放而可自由轉動。當動力工具內之氣動馬達或電動馬達不運轉時，驅動機構123內之轉子及齒輪125不轉動，因而不驅動主軸111轉動，然而此時主軸111仍有可能因慣性或其餘外力(例如使用者施加之力)而被轉動，此時與主軸111配合使用之套筒127或轉接件可能因同時被主軸111帶動而難以移除或更換，再者主軸111亦有可能因不當轉動而損壞與主軸111連動之零組件。因此當轉動鎖定機構操作於第一狀態時，主軸111被鎖定而無法轉動，有利於套筒127或轉接件之移除或更換，以及避免主軸111不當轉動而損壞與主軸111連動之零組件。當轉動鎖定機構操作於第二狀態時，主軸111可自由轉動，當動力工具內之氣動馬達或電動馬達運轉時，透過驅動機構123可帶動主軸111轉動，並透過套筒127或轉接件進行相關作業。 Please refer to Figures 3 to 6 together. Figure 3 is a schematic diagram showing the rotation and locking mechanism of this creation operating in the first state. Figure 4 is a cross-sectional view of some parts of the rotation locking mechanism of Figure 3. Figure 5 is a schematic diagram showing the rotation and locking mechanism of this creation operating in the second state. Figure 6 is a cross-sectional view of some parts of the rotation locking mechanism of Figure 5. In Figures 3 and 4, the rotation locking mechanism is in the first state, that is, the state where the spindle 111 is locked and cannot be rotated. At this time, the rotating ring 113 rotates in the first direction, and the two braking members 117b are each pushed by the two convex points 118 of the rotating ring 113 to form a displacement from the initial position, and then press against the two stop surfaces 119, so that the main shaft 111 is locked. It rotates, and the restoring pieces 117a are compressed to accumulate elastic restoring force. In Figures 5 and 6, the rotation locking mechanism is in the second state, that is, the state where the spindle 111 is released and can rotate freely. At this time, the swivel 113 rotates in the second direction, and the two convex points 118 of the swivel 113 are respectively far away from the two braking parts 117b and no longer push the two braking parts 117b, and the second braking The piece 117b is pushed by the elastic restoring force of each reset piece 117a to reset to the initial position, so the stop surface 119 is not pressed by the stopper 117b, and the spindle 111 is released and can rotate freely. When the air motor or electric motor in the power tool is not running, the rotor and gear 125 in the driving mechanism 123 do not rotate, and therefore do not drive the main shaft 111 to rotate.
