Description
本發明係一種利用固定板限制相鄰齒輪之軸心以方便組裝之制動器，尤指利用一固定板上的三個固定部，分別連接至一殼體內之固定軸及相鄰之二齒輪的軸心，以固定住該二齒輪及固定軸之相對位置，令組裝人員能先確保該二齒輪的精確囓接後，再逐一調整制動器內其他齒輪的位置，以提昇組裝效率。 The invention relates to a brake which uses a fixing plate to limit the axis of an adjacent gear to facilitate assembly, in particular, three fixing portions on a fixing plate are respectively connected to a fixed shaft in a casing and an axis of two adjacent gears. The core is fixed to the relative positions of the two gears and the fixed shaft, so that the assembler can first ensure the precise engagement of the two gears, and then adjust the positions of other gears in the brake one by one to improve the assembly efficiency.
按，機器人係自動控制機器(Robot)的俗稱，係用於協助人們進行各種具高危險性、具高精密性或需長時間反覆執行的工作，早在1980年代，便有汽車業者利用一種具多關節的機械手臂(robot arm)，來提昇生產線上的良率及製造效率。時至今日，機器人的應用領域越來越廣泛，無論是半導體、金屬加工、風機製造、太陽能製造業、食品加工與包裝、電子、製藥等產業，都可見到各種不同類型的機器人，令業者能透過生產的自動化及機械化，大幅改善生產效率、產品產能、營運成本及工安要求，並創造出更多的利潤。 According to the robot, the automatic name of the robot is used to assist people in various high-risk, high-precision or long-term repeated work. As early as the 1980s, there was a car manufacturer using a tool. A multi-joint robot arm to increase yield and manufacturing efficiency on the production line. Today, robots are becoming more and more widely used. Whether it is semiconductor, metal processing, wind turbine manufacturing, solar energy manufacturing, food processing and packaging, electronics, pharmaceuticals, etc., various types of robots can be seen, enabling operators to Through the automation and mechanization of production, the production efficiency, product capacity, operating costs and safety requirements are greatly improved, and more profits are created.
在機器人結構中，「制動器」為一個極為重要的元件，其係一種能將能量(如：電力)轉換成物理運動(如：旋轉或線性運動)的裝置，舉例而言，常見的制動器係包括一直流馬達及一減速齒輪箱，係能將 直流馬達輸出的轉動力道進行減速，並以高扭矩輸出，以帶動機器人之關節或手臂。然而，對於業者而言，組裝制動器時常費時又費力，效率不彰，主要原因在於，減速齒輪箱內係設有複數個相互囓接的齒輪，但是，由於各個齒輪可能因為生產上之公差，導致無法非常精確地樞接在箱內，故，在組裝過程中，各齒輪之間很容易略為鬆動，致使組裝人員無法精確地把每個齒輪相互囓接，以組裝完成制動器。 In the robot structure, the "brake" is an extremely important component, which is a device that can convert energy (such as electricity) into physical motion (such as rotary or linear motion). For example, common brake systems include a DC motor and a reduction gearbox The rotational force output of the DC motor is decelerated and output with high torque to drive the joint or arm of the robot. However, for the industry, the assembly of the brakes is often time-consuming, labor-intensive and inefficient. The main reason is that the reduction gearbox is provided with a plurality of gears that mesh with each other, but the gears may be due to production tolerances. It cannot be pivoted very accurately in the box, so during the assembly process, the gears are easily loosened slightly, making it impossible for the assembler to precisely engage each gear to assemble the brakes.
正因為制動器內部之齒輪不易安裝，因此，以往的制動器內皆無法配置過多的減速齒輪組，否則將會嚴重影響生產效率或良率，然而，若欲提昇制動器的效能，則勢必需要更精密的齒輪結構，故，齒輪的安裝問題可說是當前業者不得不去面對解決的一大挑戰。因此，發明人乃思及，是否能針對制動器之結構進行改善，以解決組裝效率不彰之問題？由於，制動器本身的運作原理及結構組成(即，馬達與減速齒輪組)已十分成熟，故，如何在不大幅變更制動器既有架構的情況下，進行局部改良，以令組裝人員能更迅速地將各齒輪安裝完成，即成為本發明在此亟欲解決的重要問題。 Because the internal gear of the brake is not easy to install, it is impossible to arrange too many reduction gear sets in the conventional brakes, otherwise the production efficiency or yield will be seriously affected. However, if the brake performance is to be improved, it is necessary to be more precise. Gear structure, therefore, the problem of gear installation can be said that the current industry has to face a major challenge. Therefore, the inventor thought about whether the structure of the brake can be improved to solve the problem of inaccurate assembly efficiency. Since the operating principle and structural composition of the brake itself (ie, the motor and the reduction gear set) are very mature, how to make a partial improvement without significantly changing the existing structure of the brake, so that the assembler can more quickly The installation of each gear is an important problem that the present invention is intended to solve.
有鑑於以往組裝人員在組裝制動器時，因為要同時固定每個齒輪的位置，始能令齒輪間精確囓接，致使組裝費時費力的問題，發明人憑藉著多年來的實務經驗，經過多次研究、測試與改良後，終於設計出本發明之一種利用固定板限制相鄰齒輪之軸心以方便組裝之制動器，期能有效解決習知技術之缺憾。 In view of the fact that in the past, the assembler assembled the brakes, because the position of each gear was fixed at the same time, the gears could be accurately meshed, which caused the assembly to be time-consuming and labor-intensive. The inventors have studied through many years of practical experience. After testing and improvement, the invention finally designs a brake that uses a fixing plate to limit the axis of an adjacent gear to facilitate assembly, and can effectively solve the shortcomings of the prior art.

本發明係一種利用固定板限制相鄰齒輪之軸心以方便組裝之制動器，請參閱第1~3圖所示，係本發明之第一較佳實施例，該制動器1係應用於一自動化設備上(如：機器人四肢、機器手臂關節等)，包括一殼體11、一輸入齒輪12、一輸出齒輪13、一左齒輪組A1、一右齒輪組B1及一固定板14，該殼體11內設有一容置槽110(在圖式中，係以將殼體11之一外蓋隱藏，以便於顯示該容置槽110內部配置)，且該容置槽110中設有一固定軸111。 The present invention is a brake that uses a fixed plate to limit the axis of an adjacent gear to facilitate assembly. Referring to Figures 1 to 3, which is a first preferred embodiment of the present invention, the brake 1 is applied to an automated device. The upper part (eg, the robot limbs, the robot arm joints, etc.) includes a casing 11, an input gear 12, an output gear 13, a left gear set A1, a right gear set B1, and a fixed plate 14, the casing 11 A receiving slot 110 is disposed in the drawing (in the figure, one cover of the housing 11 is hidden to facilitate the display of the internal arrangement of the receiving slot 110), and a fixing shaft 111 is disposed in the receiving slot 110.
該輸入齒輪12係設於該容置槽110內，其軸心為一輸入軸，能接收外界傳來之一驅動力，舉例而言，該制動器1內可配置一直流馬達，以直接驅動該輸入齒輪12，或該直流馬達亦可設置於該制動器1外，而透過一連接桿或齒輪，間接地帶動該輸入齒輪12之軸心。該輸出齒輪13亦設於 該容置槽110內，其軸心能伸出至該殼體11外，而形成一輸出軸(如：能連接到一機器人膝蓋，以帶動其旋轉之輸出軸)。 The input gear 12 is disposed in the accommodating groove 110, and the axial center thereof is an input shaft, and can receive a driving force from the outside. For example, the brake 1 can be configured with a DC motor to directly drive the input gear. The input gear 12, or the DC motor, may be disposed outside the brake 1 and indirectly drive the axis of the input gear 12 through a connecting rod or gear. The output gear 13 is also provided at In the accommodating groove 110, an axis thereof can protrude outside the casing 11 to form an output shaft (for example, an output shaft that can be connected to a robot knee to drive the rotation thereof).
為便於描述各組件之相對關係，後文係以第3圖之平面視圖的方向為準，說明相對位置，請參閱第1~3圖所示，該左齒輪組A1係由複數個左減速齒輪組A11~A13相互嚙接構成，各該左減速齒輪組A11~A13係樞設於該容置槽110中鄰近該固定軸111之左側位置，且其中之二個該左減速齒輪組A11、A13能分別與該輸入齒輪12及輸出齒輪13相嚙接。 In order to facilitate the description of the relative relationship of the components, the following is based on the direction of the plan view of Fig. 3, indicating the relative position, as shown in Figures 1 to 3, the left gear set A1 is composed of a plurality of left reduction gears. The groups of the left reduction gears A11 to A13 are pivotally disposed on the left side of the accommodating groove 110 adjacent to the fixed shaft 111, and two of the left reduction gear sets A11 and A13 are disposed. The input gear 12 and the output gear 13 can be respectively engaged with each other.
該右齒輪組B1係由複數個右減速齒輪組B11~B13相互嚙接構成，各該右減速齒輪組B11~B13係樞設於該容置槽110中鄰近該固定軸111之右側位置，且其中之二個該右減速齒輪組B11、B13能分別與該輸入齒輪12及輸出齒輪13相嚙接。以往，習知的制動器受限於前述之安裝考量，內部多僅配置有一組齒輪組，而本案之制動器經改良後，即便配置多組齒輪組(本實施例中僅以兩組為例說明)，亦不會產生安裝困難的問題。 The right gear set B1 is formed by a plurality of right reduction gear sets B11-B13, and each of the right reduction gear sets B11-B13 is pivotally disposed in the accommodating groove 110 adjacent to the right side of the fixed shaft 111, and Two of the right reduction gear sets B11, B13 can be engaged with the input gear 12 and the output gear 13, respectively. In the past, the conventional brakes are limited by the above-mentioned installation considerations, and only a set of gear sets are disposed inside, and the brakes of the present invention are improved, even if multiple sets of gear sets are arranged (in this embodiment, only two groups are taken as an example) There will be no problem of difficulty in installation.
在該實施例中，復請參閱第1~3圖所示，該固定板14上設有三個固定部141(如：一嵌卡孔)，各該固定部141之構形係分別與該固定軸111及二個左減速齒輪組A12、A13的軸心相匹配，以能分別與該固定軸111及相鄰近之二個左減速齒輪組A12、A13的軸心相連接，進而固定住該二個左減速齒輪組A12、A13與該固定軸111間的相對位置。惟，在本發明之其它實施例中，該固定板14亦可組裝至右齒輪組B1，並非僅限定於前述的左齒輪組A1，合先陳明。 In this embodiment, as shown in FIGS. 1~3, the fixing plate 14 is provided with three fixing portions 141 (such as a card insertion hole), and the fixing portions 141 are respectively fixed and fixed. The shafts 111 and the shafts of the two left reduction gear sets A12 and A13 are matched to be respectively connected to the shafts of the fixed shafts 111 and the two adjacent left reduction gear sets A12 and A13, thereby fixing the two The relative position between the left reduction gear sets A12, A13 and the fixed shaft 111. However, in other embodiments of the present invention, the fixing plate 14 may be assembled to the right gear set B1, and is not limited to the aforementioned left gear set A1.
如此，復請參閱第1~3圖所示，作業人員在組裝該制動器1時，即能優先對準該二個左減速齒輪組A12、A13，以使該二個左減速齒輪 組A12、A13間的齒部能相互嚙接，嗣，透過該固定板14，固定住該二個左減速齒輪組A12、A13與該固定軸111間的相對位置，確保該二個左減速齒輪組A12、A13不會因為製造上之公差或外力震動，導致其位置略為鬆動而解除嚙接狀態；當該左齒輪組A1已組裝至殼體11內，且左減速齒輪組A11與輸入齒輪12相嚙接後，工作人員能逐一組裝右減速齒輪組B11~B13，此時，當輸入齒輪12因前述組裝過程，而發生轉動的情況下，藉由該固定板14之作用，能確保該左減速齒輪組A11~A13被一同帶動旋轉，故，工作人員能藉逐一調整各該左齒輪組A1與右齒輪組B1中各個齒輪的位置，使得每個齒輪的齒部皆能準確嚙接，據此，即可解決組裝人員以往在安裝複數個齒輪時，難以同時兼顧每個齒輪在準確的嚙接位置，導致在組裝上發生費時又費力且嚙接不精準的問題。 Thus, referring to Figures 1 to 3, when the operator assembles the brake 1, the two left reduction gear sets A12 and A13 can be preferentially aligned to make the two left reduction gears. The teeth between the groups A12 and A13 can be engaged with each other. Through the fixing plate 14, the relative positions between the two left reduction gear sets A12 and A13 and the fixed shaft 111 are fixed to ensure the two left reduction gears. The groups A12, A13 do not vibrate due to manufacturing tolerances or external forces, causing their position to be slightly loose to release the engaged state; when the left gear set A1 has been assembled into the housing 11, and the left reduction gear set A11 and the input gear 12 After the engagement, the worker can assemble the right reduction gear set B11~B13 one by one. At this time, when the input gear 12 rotates due to the assembly process described above, the left side of the fixing plate 14 can ensure the left side. The reduction gear sets A11~A13 are rotated together, so that the staff can adjust the positions of the respective gears in each of the left gear set A1 and the right gear set B1 one by one, so that the teeth of each gear can be accurately engaged. Therefore, it can be solved by the assembler that when installing a plurality of gears in the past, it is difficult to simultaneously take care of each gear in an accurate engagement position, which causes a problem of time-consuming and laborious assembly and inaccurate engagement.
在本實施例中，該等固定部141分別為一嵌卡孔，各該嵌卡孔能與該等左減速齒輪組A12、A13及該固定軸111之軸心相嵌卡而樞接在一起。惟，在本發明之其他實施例中，該等固定部141亦可為其他構形，例如：若該等左減速齒輪組A12、A13及該固定軸111之軸心上皆設有一穿孔，則該等固定部141之構形可為一嵌卡柱，以嵌入該穿孔中完成固定。 In this embodiment, the fixing portions 141 are respectively an insertion hole, and each of the insertion holes can be pivotally coupled with the axes of the left reduction gear sets A12 and A13 and the fixed shaft 111. . However, in other embodiments of the present invention, the fixing portions 141 may be in other configurations, for example, if a perforation is formed in the axes of the left reduction gear sets A12 and A13 and the fixed shaft 111, The fixing portion 141 can be configured as an embedded post to be embedded in the through hole for fixing.
另，茲進一步詳述該等齒輪組A1、B1之結構如下：該左齒輪組A1包括一第一左減速齒輪組A11、一第二左減速齒輪組A12、一第三左減速齒輪組A13，其中，該第一左減速齒輪組A11輪軸之一端係樞接至該殼體11，且沿軸向設有一第一大左齒輪A111及一第一小左齒輪A112，該第一大左齒輪A111能與該輸入齒輪12相囓接。該第二左減速齒輪組A12輪軸之一端係樞接至該殼體11，且沿軸向設有一第二大左齒輪A121及一第二小左齒 輪A122，該第二大左齒輪A121能與該第一小左齒輪A112相囓接。該第三左減速齒輪組A13輪軸係樞接至該殼體11，且沿軸向設有一第三大左齒輪A131及一第三小左齒輪A132，該第三大左齒輪A131能與該第二小左齒輪A122相囓接，該第三小左齒輪A132則能與該輸出齒輪13相嚙接。 In addition, the structure of the gear sets A1, B1 is further described as follows: the left gear set A1 includes a first left reduction gear set A11, a second left reduction gear set A12, and a third left reduction gear set A13.
