the expansion and contraction of a rod for linear rotation by rotation of an electric motor used as a driving source of a sorting mechanism of a conveying device or an actuator of a precision machine. The linear motion of the movement is particularly related to the linear motion of the servo motor used in the field where high speed and large thrust, high stopping accuracy, and high frequency forward and reverse operation are required. [Prior Art] In the past, a motor-driven linear actuator has a screw having a lead screw that is rotationally driven, a screw that is screwed to the lead screw, and linearly moves in the axial direction when the lead screw is rotationally driven, and is coupled to the nut. A rod (inner cylinder) that moves linearly with the nut in the axial direction' limits the movement of the stopper, the inner rod and the main body (outer cylinder) of the stopper (for example, refer to the patent document ^ [Patent Document 1] JP-A-2001-221313 (Specific reference to page 3, FIG. 1) [Summary of the Invention] However, as in the conventional linear actuator described above, a general-purpose motor is used as a driving source, which is not suitable for It is required to be used in the field of high speed and high thrust, high stopping accuracy, and high frequency forward and reverse operation. Moreover, although a servo motor has been used as a driving source, a ball screw is used for the lead screw to correspond to high speed and large thrust, The high stop accuracy and the high frequency forward and reverse operation are high, but the servo motor may have the length of the rotary shaft due to the difference in output capacity and the manufacturer's difference of 5 1373578. Since the mounting hole pitch and the like are different, it is necessary to prepare a special material for the actuator that constitutes a linear actuator corresponding to the feeding motor used (4). The increase in the number of stock materials is a cause of cost increase. As described above, the linear actuator with the servo motor has the requirement that the direction of the advance and retreat of the rod is vertical or oblique. However, since the linear motion of the servo motor has not been considered, the forward and backward directions of the rod are vertical or oblique. Therefore, when the forward and backward direction of the rod is used in the vertical direction or the oblique direction, the butter of the rolling screw portion is lowered to the servo motor side, enters the inside of the servo motor, and is attached to the encoder installed in the feeding motor to feed the motor. The problem of the rotation stop or the failure to control normally. The technical problem to be solved by the present invention, that is, the object of the present invention is to provide a manufacturer that does not increase the number of special components of the actuator constituting the linear actuator. Or output a servo motor of a plurality of different capacities or sizes, and even in the direction of the advancement and retreat of the linear actuator rod is vertical or The use of Xiao also prevents the butter from entering the straight line of the feeding motor inside the motor. First, the invention of the scope of the patent scope is selected from a plurality of servo motor groups having different output capacities and sizes. a servo motor, a connector fitted to the rotating shaft of the servo motor, a connector housing covering the connector, a motor flange mounted between the connector housing and a surface of the rotating shaft of the servo motor, a lead screw connected to the rotating shaft through the connector, a bearing seat in which a bearing for supporting the lead screw is mounted, and a fixing nut screwed to the lead screw between the bearing housing and the connector 6 1373578 In the linear motion of the feeding machine motor, the connector housing has a shape suitable for the minimum size of the servo motor included in the servo motor group, and the connector is suitable for the servo of the maximum capacity of the servo motor group. a motor and the hub of the connector has a maximum allowable shaft diameter larger than a maximum shaft diameter of the servo motor included in the servo motor group. From the first preparation is selected corresponding to the solving the aforementioned problems comprising a plurality of mounting to the flange portion and the thickness and size of each of the output ri servo motor of the servo motor of the group of. = Here, the connector is "suitable" for the servo motor included in the largest servo motor group, which means that the connector can tolerate a torque greater than the torque of the servo motor included in the maximum capacity of the servo motor group. The outer diameter of the hub that determines the strength of the connector is greater than or equal to the torque of the servo motor that can withstand the maximum capacity of the servo motor group. In addition, "a plurality of servo motor groups whose output capacity differs from the size" refers to a collection of servo motors of different manufacturers and models, but does not actually refer to a collection of all commercially available motor motors. A set of servo horses that adjust the mounting portion of the motor flange and the thickness of the flange to be combined with a linear actuator. The invention of claim 2 of the fourth aspect of the invention is the above-mentioned lead screw and the aforementioned bearing are suitable for the maximum capacity of the aforementioned servo motor group by the linear actuator having the servo motor of the first application of the patent scope. The servo motor further solves the aforementioned problems. Here, the size of the so-called lead screw and the aforementioned bearing is "eight" σ J in the servo motor included in the maximum capacity of the servo motor group, which is the size of the screw that determines the strength of the lead 7 1373578 and the lead screw of the shaft. The size of the bearing is included in the servo motor of the maximum capacity of the aforementioned servo motor group: the moment is smaller than the smaller. The invention of claim 3 of the patent application scope is the straight line of the servo motor of the second or second application patent scope. In the driving mechanism, the fixing nut has a ring-shaped convex portion on the bearing housing side, and an oil seal is disposed on the outer circumference of the annular convex portion, and a sealing cover that houses and supports the oil sealing member is fixed to the wheel The above-mentioned problem is further solved by the bearing. The linear actuator with the servo motor of the present invention has one servo motor selected from a plurality of servo motor groups having different output capacities and sizes, and the rotary shaft of the servo motor is embedded. a connector, a connector housing covering the connector, a motor flange mounted between the connector housing and a surface of the servo motor having a rotating shaft, and transmitting through the The bearing is coupled to the rotating surface of the rotating surface, and the bearing seat of the bearing of the guiding screw is screwed to the fixing nut of the lead screw between the bearing seat and the connector. Therefore, the combination of the lead screw and the connector described above does not cause a failure of the key connection, and the performance of the servo motor is maximized, so that high speed and high thrust, high stop accuracy, and high frequency positive and negative can be realized. In addition to the operation, a special effect corresponding to the specific composition as described below can be exerted. With the linear motion of the servo motor of the first application of the patent scope, the connector housing has a minimum size suitable for inclusion in the servo motor group. The shape of the servo motor, the connector is suitable for the servo motor of the maximum capacity of the servo motor group, and the maximum allowable shaft diameter of the hub of the connector is larger than the maximum shaft diameter of the servo motor included in the servo motor group, and the motor flange is 8 I373578 In the plural of the mounting portion and the flange thickness which are prepared in advance and have the wheel capacity and size corresponding to each of the motor motors included in the motor group By changing only the motor λ edge, it is possible to correspond to each servo motor of the feed motor group in which the output capacity and the size are different, and the other components constituting the linear actuator can be common, so that it is not necessary to use the corresponding servo motor. The special part of the actuator that constitutes the linear actuator can reduce the number of parts in stock to reduce the cost. • That is, the connector housing has the smallest size suitable for inclusion in the servo motor group (the length of the protruding rotating shaft is the smallest) The shape of the servo motor. When installing a large-sized servo motor, changing the thickness of the motor flange can make the distance between the motor rotating shaft and the axial surface of the lead screw uniform. Therefore, the connector peripherals do not have to be included in the servo motor group. Each servo motor can be changed to be common. In addition, by adapting the connector to the servo motor of the maximum capacity of the servo motor group and making the maximum allowable shaft diameter of the hub of the connector larger than the motor group The maximum shaft diameter of the servo motor, the connector pair includes • the other low-capacity and fine-axis servo of the servo motor group Has a margin amounted to convey, aspects of the strength of the shaft diameter moment. And the shaft aperture of the hub of the connector can be concluded by a lock screw. Therefore, even a servo motor without a keyway can be installed. With the linear motion of the servo motor in the second application of the patent application, the size of the lead screw and the aforementioned bearing in the linear actuator with the servo motor of the first application of the patent scope is suitable for inclusion in the aforementioned servo motor group. The servo motor with the largest capacity, the lead screw and bearing 9 1373578 on the output side: the allowable strength t is greater than the torque of all the feeding motors connected to the wheel entry side. Because the guide screw # and the bearing do not have to be common with each of the feed motor groups included in the storage motor group, and (4) apply for the third line of the patent scope, the straight line for the motor is =, in the scope of the patent application... In the linear motion of the feeding motor, the oil-sealing member is provided on the outer side of the bearing housing side with an annular convex annular convex portion, and the inner seal is fitted with the front mark and the cow The reading cover is attached to the bearing housing, and the butter of the oil sealing rod enters the feeding motor side, so that even when the straight line or the oblique direction is set, the butter is prevented from entering the inside of the feeding motor, and the stable operation can be realized.

In the present embodiment, two tapered roller bearings of a roller bearing, that is, a so-called tapered bearing, are disposed separately as two bearings. By adopting such a configuration, the load received from the guide screw #170 is not subjected to the line bearing as the ball bearing is received by the wire, so that the load can be withstand high and the deflection of the lead screw 170 can be suppressed by separating the two tapered bearings. Therefore, the positive and negative rotation of stability can be achieved. Further, the lead screw 170 is screwed with a nut 172 as shown in Fig. 1, and the ball screw is formed so that the steel ball rotates between the lead screw 17 () and the yoke 172, and the friction coefficient is extremely small. the following. Therefore, since the transmission efficiency is 90% or more and the starting torque of the starting six extension is also less than 1/3 of the sliding screw, it is particularly suitable for use in the field where high frequency forward and reverse operation is required. And having a rod 172 coupled to the nut 172 and interposing the lead screw 17 〇 and corresponding to the lead screw 170 of the lead screw 170 to move forward and backward in the axial direction, (4) inserting the rod 174 A main body (10) is provided. One end of the main body (10) is 'embedded to the bearing seat' of the bearing seat 150' as shown in Fig. 2. In addition, the front end of the rod 174 is provided with a front end ring 178 connected to the load. Further, the bearing 12 1373578 seat 150 The inner peripheral surface of the opening on the side of the main body 180 is threaded, and a stopper plate 156 that prevents the nut 172 from biting against the bearing 160 side is screwed in. The connector housing 130 has a minimum size suitable for inclusion in the aforementioned servo motor group. By the shape of the servo motor, it is not possible to reach the connector 13 2 without using any of the servo motors included in the servo motor group through the motor flange 1 to be described later. Further, the connector 132 uses a high-torque rigidity, a small size and light weight, and is excellent in followability to the servo motor 190, and is suitable for precision control of the disk connector. Moreover, the servo is suitable for the maximum capacity included in the servo motor group. The motor 190 also sets the maximum allowable shaft hole of the hub of the connector 132 to be larger than the maximum shaft diameter of the servo motor included in the servo motor group, and does not need to change the connection of all the servo motors 190 included in the servo motor group. The size of the knot 132 is such that the rotating shaft 110 is coupled to the lead screw 170. Further, the connector housing 13 is disposed between the connector housing 丨3 and the surface of the servo motor 190 having the rotating shaft 11〇. The motor flange is prepared in advance with a plurality of motor flanges U0' having a mounting portion and a flange thickness corresponding to the output grain amount and size of each servo motor included in the servo motor group, which are connected to a straight line as shown in FIG. The servo motor of the motive is selected. That is, Fig. 3 is a side view showing an example of a servo motor corresponding to a manufacturer or a model. In this embodiment, there are different words in the servo motor group. The motor flanges 122, 124 and 26 of the mounting dimensions of the motor bodies 192, 194, and 196 have different lengths of the rotating shafts of the servo motors 192, 194, and 190, 13 1373578. Therefore, by the motor flanges 122, 124, The flange thicknesses T1, .T2, and T3 of 126 correspond to the length of the rotation axis of each servo motor, so that the distance g between the rotation axis n〇 and the axial surface of the lead screw 170 (refer to FIG. 2) is relative to the servo motor group. All servo motors 19 2. 194, 196 are constant. In the present embodiment, although the shape of each of the feeding motor included in the servo motor group and the mounting portion of the motor flange is the same, it may be changed by the servo motor according to the use. The shape of the mounting portion of the motor flange, that is, the mounting hole pitch size and the mounting angle size, corresponds to more types of service horses. For example, the mounting angle of the servo motor 290 shown in Fig. 10(a) L1 is substantially equal to the opening size C1 of the connector housing 130, that is, when L1 and C1, the motor flange 220 has a engaging section 22〇& and has a plug-in rotation at the center on the surface that engages with the connector 13〇. The shaft hole 22〇b of the shaft 170 has a substantially quadrangular prism shape having a screw hole 220c at a position where it is screwed into the bolt 29〇b inserted through the mounting hole of the weir portion 290a of the servo motor 290. Further, for example, when the mounting angle of the servo motor 390 shown in Fig. Hb) is larger than the opening size C2 of the connector housing 130, that is, L2 > C2, the motor flange 320 has a engagement with the surface of the connector 130. The segment portion 32〇& has a shaft hole 32〇b inserted through the rotating shaft 17〇 at the center, and is screwed into the bolt 39〇b which is inserted into the mounting hole of the flange portion 39 of the servo motor 390. The position has a generally quadrangular pyramid shape with a screw hole 320c. Further, the size of the strength of the lead screw 17 is determined to be equal to or greater than the magnitude of the torque of the bearing 16 轴 of the shaft of the servo motor group. Thereby, the allowable strength of the guide cup 170 and the bearing 16 of the output side of the 1373578 can be greater than the torque of the feeding motor 19〇 connected to the servo motor group connected to the input side, and does not have to be included in the feeding motor group. Each of the words of the motor change lead screw 17〇 and the bearing 160' can be used in common for each servo motor. Further, the guide screw spun 170 is shown in Fig. 2, and has a screw portion md which is screwed to the nut i 72 and constitutes the ball screw #. The extension end is at the end and the lead screw 17G is the smallest diameter and is not threaded and is connected to the joint portion 17〇a of the connection f U2, the shaft branch which is thicker than the joint portion and is not engraved with the thread bearing 160 17〇c, is provided in the pumping portion i7〇c and the threaded portion 170d and is higher than the 钕 钕 u - - 匕 匕 匕 匕 匕 匕 匕 170 170 170 170 d d d d d d d d d d d ° ° ° ° ° ° ° ° ° ° ° ° ° ° A) A collar portion 170e from which the motor direction is detached, and a support portion (four) for preventing the lead screw m from passing to the other end 1 between the joint portion 1 70a and the shaft branch portion i 7〇c.
