Description
Technical Field
[0001] The present invention relates to the technical field of motor assembly equipment, and particularly relates to an oiling device for rotor bearings, a motor rotor assembly, and a motor assembly system. Background Art
[0002] In the EPS motor assembly process, it is divided into stator assembly, rotor assembly, and assembling the stator assembly and the rotor assembly together to form the final motor product. During the rotor assembly process, procedures such as inserting magnets, magnetizing, installing stainless steel sleeves, and installing bearings are required. And two rotors need to be stacked at a certain angle. The conventional operation method in the prior art is usually to first use a transfer hand to grab two rotors, and then use a rotating mechanism to rotate one of the rotors by a certain angle and then stack them. Such an operation method requires an additional device and has low efficiency. In addition, the following problems also exist in the existing motors during the rotor assembly process.
[0003] 1. In the conventional process, the rotor needs to be cleaned before magnetizing. During the cleaning process, a fan is often used for blowing, and such a method has insufficient cleaning strength. And after the rotor is magnetized, since the rotor is magnetic, it is more likely to adsorb iron filings and dust, etc. However, in the prior art, the rotor is not cleaned again after magnetizing. 2. During the process of oiling the sealing ring on the rotor bearing, an oil outlet block with an oil cavity is directly used, and an oil outlet hole is provided at its end, and the oil outlet hole is directly aligned with the rotor bearing for oiling. Such a method will cause the problem of uneven oiling during the oiling process. 3. During the process of installing the stainless steel sleeve on the rotor, the stainless steel sleeve has a structure with one end sealed and the other end unsealed before installation so that the rotor can be inserted into it. After the rotor is inserted into the stainless steel sleeve, the unsealed side of the stainless steel sleeve needs to be sealed. In the prior art, a pressing block with a specific angle is directly used, which is aligned with one side of the stainless steel sleeve to press and tilt the stainless steel sleeve at a certain angle, and then the stainless steel sleeve is rotated one circle to complete the sealing of the stainless steel sleeve by the pressing block. Such an operation method has low efficiency, and an additional mechanism is required to realize the rotation of the stainless steel sleeve (rotor assembly) during this process.
[0004] In addition, during the process of assembling the rotor assembly and the stator assembly, it is necessary to install a wire protection sleeve on the lead wire on the stator. However, in the previous process of the stator assembly, the lead wire on it usually cannot be guaranteed to be in an upright state. At this time, for the installation of the wire protection sleeve, the assembly worker needs to straighten the wire first or use equipment to straighten it so that the wire protection sleeve can be installed smoothly. Such an operation greatly reduces the assembly efficiency. Summary of the Invention

[0038] The following further describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Any improvement or substitution based on the basic spirit of this embodiment still falls within the scope protected by the claims of the present invention.
[0039] Embodiment 1: As Figure 1-11 shown, this embodiment provides a motor rotor assembly system, including a rotor loading device, a rotor magnet inserting device, a first dust removal device, a rotor magnetizing device, a steel sleeve assembling device, a second dust removal device, and a rotor bearing oiling device connected in a process sequence. These devices can be installed on the same machine table or separately on different machine tables.
[0040] Among them, the rotor loading device is the same as the prior art, that is, the transportation line and the gripper are used to grab the two onto the workbench surface, and the specific structure is not described in detail in this embodiment
[0041] Regarding the rotor magnetic insertion device, the magnetic insertion part is prior art and will not be elaborated in this embodiment. However, after the rotor is magnetically inserted, a rotor handling device 100 is required to grasp two rotors and stack them vertically one above the other at a certain angle. The rotor handling device includes two rotor transfer columns 101 vertically installed on the machine table. A transfer horizontal slide rail 102 is provided on the rotor transfer column, and a rotor gripper assembly is provided on the transfer horizontal slide rail. In this embodiment, the rotor gripper assembly includes a gripper slider 103 slidably connected to the transfer horizontal slide rail. A gripper adapter block 104 is installed on the gripper slider. A gripper vertical slide rail 105 is provided on the gripper adapter block. A gripper vertical slider 106 is slidably provided on the gripper vertical slide rail. A gripper fixing plate 107 is connected to the gripper vertical slider. A gripper connecting piece 108 is connected to the bottom of the gripper fixing plate. Two grippers 109 are provided in the longitudinal direction on the gripper connecting piece. One gripper is inwardly close to the transfer horizontal slide rail, and the other gripper is outwardly away from the transfer horizontal slide rail. Among them, a gripper rotating shaft 110 is provided at the top of the gripper inwardly close to the transfer horizontal slide rail. The gripper rotating shaft is installed on the gripper connecting piece through a bearing. A gripper rotating motor 111 is also provided on the gripper connecting piece. The output shaft of the gripper rotating motor is connected to the gripper rotating shaft through a pulley structure 112. In this way, when the gripper grasps the rotor, the gripper inwardly close to the transfer horizontal slide rail can drive the rotor to rotate through the motor at the same time, rotate to the angle required for the motor rotor assembly, and cooperate with the rotor grasped by the gripper outwardly away from the transfer horizontal slide rail. In this way, the grasping and angle rotation of the rotor are completed at the same time, improving the efficiency.
[0042] Regarding the first dust removal device: After the rotor is magnetically inserted, the rotor needs to be dusted. In this embodiment, the first dust removal device 200 includes a vibration mechanism 201 installed on the machine table. The vibration mechanism includes a vibration disk 202 at the top. Four dust removal columns 203 are installed above the vibration disk. A dust removal carrier plate 204 is installed at the top of the dust removal column. A rotor positioning plate 205 is installed on the upper part of the dust removal carrier plate. A rotor installation area is provided on the rotor positioning plate. Dust removal holes 206 are provided in the rotor installation area. A dust removal round hole is provided on the dust removal carrier plate. The dust removal round hole covers the dust removal holes. A dust removal pipe 207 is connected below the dust removal round hole. A dust removal fan is also provided above the rotor positioning plate, and the air outlet of the dust removal fan faces downward. The first dust removal device of this embodiment uses a combination of blowing and vibration to clean the dust and iron filings on the rotor body, and the cleaning effect is more ideal than the ordinary cleaning method that only relies on blowing.
[0043] The rotor magnetizing device in this embodiment is the same as the prior art and will not be elaborated in this embodiment.
[0044] Regarding the steel sleeve assembling device: During the rotor assembling process, it is necessary to put a stainless-steel sleeve on the outside of the two stacked rotors. In this embodiment, the installation of the stainless-steel sleeve on the rotor is the same as the prior art, and both adopt the hot-fitting method. Therefore, this embodiment will not elaborate on this. However, after installing the rotor into the stainless-steel sleeve, it is also necessary to seal the unsealed side of the stainless-steel sleeve (usually the other end of the stainless-steel sleeve has been pre-sealed). The prior art approach is to use a pressure head to apply pressure to the edge of the stainless-steel sleeve at a fixed angle, and then rotate the rotor assembly together with the stainless-steel sleeve by 360° to achieve the sealing of the stainless-steel sleeve. Such a method is too inefficient.
[0045] In this embodiment, the steel sleeve assembling device is designed with a new edge-sealing device 300. The edge-sealing device includes an edge-sealing column 301 installed on the machine table. A vertically sliding edge-sealing press head assembly 302 is arranged on the edge-sealing column. The edge-sealing press head assembly is driven by a driving mechanism (usually a cylinder) to move up and down along the column. In this embodiment, the edge-sealing press head assembly includes an inner press head 303 and an outer press head 304. Both the outer press head and the inner press head are hollow columns, and the outer diameter of the inner press head is smaller than the inner diameter of the outer press head. The inner press head is installed in the inner cavity of the outer press head through a pin 305. The bottom surface of the outer press head is annular and is provided with an inclined surface 307 with an inward taper. The tapered inclined surface of the outer press head is provided with two tapers along the radial direction, namely an inner taper near the inner circle and an outer taper near the outer circle. The angle of the outer taper is greater than that of the inner taper, and the inner taper is the edge-sealing angle that the final stainless steel sleeve should reach. The bottom surface of the inner press head is a circular plane. A horizontal radial through hole 306 is arranged at the upper part of the inner press head. The cross-section of the radial through hole is elliptical and the long side is in the vertical direction. The pin passes through the radial through hole to connect the inner press head and the outer press head. The diameter of the pin is slightly smaller than the short side of the radial through hole so that the inner press head can move up and down relative to the outer press head in the inner cavity of the outer press head. When the circular bottom surface of the inner press head does not contact the rotor assembly, the pin is located at the uppermost end of the radial through hole, and the circular bottom surface of the inner press head extends out of the inner cavity of the outer press head. During the downward movement of the edge-sealing press head assembly, the circular lower end surface of the inner press head first contacts the upper end surface of the rotor assembly, and the annular inclined surface of the bottom surface of the outer press head contacts the outer wall of the stainless steel sleeve on the outer circle of the rotor assembly, and the stainless steel sleeve is inclined inward during the gradual downward pressing. When the edge-sealing press head assembly is pressed down until the pin is located at the lowermost end of the radial through hole of the inner press head, it means that the pressing is in place. At this time, the annular inclined surface of the bottom surface of the outer press head has pressed all the edges of the stainless steel sleeve to the inner taper near the inner circle of its inclined surface, so that the stainless steel sleeve reaches the edge-sealing angle required by the design. Then drive the edge-sealing press head assembly to move upward away from the rotor assembly, thus completing the edge-sealing procedure of the stainless steel sleeve.
[0046] In addition, the steel sleeve assembling device further includes a horizontal slide rail for the movement of the rotor assembly located below the edge-sealing device. A rotor assembly fixture is arranged on the horizontal slide rail. The rotor assembly is installed on the rotor assembly fixture and then driven to the lower part of the edge-sealing device by a driving mechanism (usually a cylinder / electric cylinder). Then, the edge-sealing press head assembly of the closing device is driven by a driving mechanism to move downward to perform edge-sealing of the stainless steel sleeve on the rotor assembly on the rotor assembly fixture. In this way, the edge-sealing accuracy and efficiency of the stainless steel sleeve are improved.
[0047] Regarding the second dust removal device: After putting a stainless steel sleeve on the rotor assembly, in this embodiment, a second dust removal device 400 for secondary cleaning of the stainless steel sleeve of the rotor assembly is designed. After the rotor is magnetized, it is easy to adsorb some dust and iron filings. At this time, the method of vibration + blowing for cleaning has low efficiency and poor effect. This embodiment provides a second dust removal device for after the rotor is magnetized and the stainless steel sleeve is installed. The second dust removal device includes a frame 401 arranged on the machine table. Two dust removal shafts 402 with the same rotation direction are arranged in parallel on the frame. Both of the two dust removal shafts are driven to rotate by a dust removal motor. An unused dust removal tape loop 403 is sleeved on one of the dust removal shafts, and a used recovery tape loop 404 is sleeved on the other dust removal shaft. It further includes two tension shafts 405 and a dust sticking shaft 406 arranged on the same side of the two dust removal shafts. The tension shafts and the dust sticking shaft are arranged in a triangle, and the dust sticking shaft is located at the outermost part of the triangle. The tape of the dust removal tape loop sequentially bypasses the tension shafts, the dust sticking shaft, and the tension shafts with the glue side facing outward and then winds onto the recovery tape loop. A rotor assembly dust removal slider 407 is arranged adjacent to the dust sticking shaft. The rotor assembly dust removal slider slides on a dust removal guide rail 408. The dust removal guide rail is installed on the machine table, and a dust removal cylinder connected to the screw nut of the rotor assembly dust removal slider is arranged at one end of the dust removal guide rail. A rotor assembly installation jig is arranged on the rotor assembly installation slider. A rotating shaft is arranged at the lower part of the rotor assembly installation jig. The rotating shaft is installed on the rotor assembly installation slider through a mounting bearing. A motor for driving the rotor assembly installation jig to rotate is further arranged at the bottom of the rotor bearing installation slider. Place the rotor assembly on the rotor assembly installation jig, and drive the rotor assembly to rotate through the motor drive. Of course, other methods can also be adopted to make the rotor assembly rotate.
[0048] In addition, as one of the implementation manners in this embodiment, a limiting block for limiting the tape is further arranged between the tension shaft and the dust sticking shaft. The limiting block is a concave block 409 facing the tape.
[0049] During use, the dust removal motor drives the dust removal shaft to rotate, so that the unused tape rotates between the dust removal shaft (dust removal tape loop) - tension shaft - dust sticking shaft - tension shaft - dust removal shaft (recovery tape loop). And when the unused tape rotates on the dust sticking shaft, it can contact the surface of the stainless steel sleeve of the rotor assembly driven by the motor. The tape bonds and tears off the surface of the stainless steel sleeve, and can stick and take away the dust and iron filings on the surface of the stainless steel sleeve and wind them onto the dust removal shaft where the recovery tape loop is located. Such a dust removal method is especially suitable for the surface of the stainless steel sleeve of the magnetized rotor assembly, and can effectively remove the dust and iron filings on its surface, with remarkable effect.
[0050] Regarding the rotor bearing oiling device: After the surface of the stainless steel sleeve of the rotor assembly is dusted, the rotor shaft needs to be installed on the rotor, and the rotor bearing also needs to be sleeved on the rotor shaft. The rotor bearing is used for installation with the motor housing. Before installation with the housing, the sealing ring on the surface of the rotor bearing needs to be oiled to facilitate smoother installation with the housing. Usually, the rotor bearing is installed on the rotor shaft by press-fitting, which is an existing conventional technology and will not be elaborated in this embodiment. However, when oiling the sealing ring on the surface of the rotor bearing, this embodiment provides a new rotor bearing oiling device.
[0051] The rotor bearing oiling device 500 in this embodiment includes an oiling device bottom plate 501 arranged on the machine table. A vertical left support plate 502 and a right support plate 503 are installed on the oiling device bottom plate. The top of the left support plate and the right support plate is provided with an oil outlet top plate 504. Two parallel longitudinal guide rails 505 are installed on the oil outlet top plate. A longitudinal slide plate 506 is slidably arranged on the longitudinal guide rails. A longitudinal driving motor 507 is installed on one side of the oil outlet top plate. The longitudinal driving motor is connected to the longitudinal slide plate in a screw-nut manner to drive the longitudinal slide plate to slide back and forth. In this embodiment, the oil outlet top plate is U-shaped, the longitudinal driving motor is arranged on the transverse plate surface of the U-shaped oil outlet top plate, and the two longitudinal guide rails are respectively arranged on the two longitudinal plate surfaces of the U-shaped oil outlet top plate. And the oiling mechanism is installed on the longitudinal slide plate, and a rotor assembly support mechanism adjacent to the oiling mechanism is arranged in front of the oiling mechanism (away from the longitudinal driving cylinder).
[0052] Among them, the oiling mechanism includes an adjacent oiling roller assembly 508 and an oil outlet adjusting assembly 509. The oiling roller assembly is arranged between the oil outlet adjusting assembly and the rotor assembly support mechanism. In this embodiment, a T-shaped extended plate extending forward is installed on the front side of the longitudinal slide plate. The oil outlet adjusting assembly is installed on the longitudinal slide plate, and the oiling roller assembly is installed on the T-shaped extended plate. The oiling roller assembly includes an oiling roller 511 and an oil receiving tray 512. The oiling roller and the oil receiving tray are installed on the same vertical rotating shaft 513, and the oiling roller is located above the oil receiving tray. The area of the oil receiving tray is larger than that of the oiling roller to catch the lubricating oil falling on the oiling roller. The vertical rotating shaft is installed on the T-shaped extended plate through a bearing. A motor 514 is fixed at the bottom of the longitudinal slide plate. The output shaft of the motor passes through the longitudinal slide plate through a bearing and extends out from the upper surface of the longitudinal slide plate. The output shaft of the motor is connected to the vertical rotating shaft through a pulley structure 515, so that the motor drives the vertical rotating shaft to rotate. The oil receiving tray is installed on the vertical rotating shaft through a bearing, and the oil receiving tray will not be driven to rotate by the vertical rotating shaft. The oiling roller is fixedly installed on the vertical rotating shaft. When the motor drives the vertical rotating shaft to rotate, the oiling roller will also rotate synchronously. In addition, an arc-shaped notch 516 for the rotor assembly to give way is provided at the position where the oil receiving tray in this embodiment faces the rotor assembly support mechanism.
[0053] The oil outlet regulating assembly includes an oil outlet regulating mounting plate 517, which is an inverted U-shaped plate. The inverted U-shaped plate is mounted on the longitudinal slide and the motor output shaft is located below the U-shaped plate. An oil outlet regulating valve is mounted on the oil outlet regulating mounting plate. The oil outlet regulating valve includes an oil outlet regulating block 518 mounted on the top surface of the U-shaped plate. The oil outlet regulating block is provided with an oil cavity 519 with a top opening. The top of the oil cavity is provided with an oil cavity sealing plate 520. The oil cavity sealing plate is provided with an oil inlet hole 521, and the oil inlet hole is connected to an oil inlet pipeline. The side of the oil outlet regulating block opposite to the oil coating roller is provided with an arc-shaped oil outlet surface 522, and an oil outlet hole 523 is provided on the arc-shaped oil outlet surface, and the oil outlet hole is connected to the oil cavity. The arc surface of the arc-shaped oil outlet surface matches the outer surface of the oil coating roller and there is an oil outlet gap, that is, the circle where the arc-shaped oil outlet surface is located is concentric with the circle where the outer surface of the oil coating roller is located. The oil outlet hole can be set to one or more. In this embodiment, the oil outlet hole is set to three parallel in the circumferential direction. In addition, the upper and lower ends of the arc-shaped oil outlet surface are respectively provided with limit plates 524 extending toward the oiling roller along the arc line, and the upper and lower limit plates and the arc-shaped oil outlet surface form an oil covering groove for accommodating the oiling roller, and the oil outlet hole on the arc-shaped oil outlet surface and the oiling surface of the oiling roller form an oil covering port. In this embodiment, the limit plate is also arc-shaped and the extended part covers the oiling roller. The other end of the oil outlet adjustment block is provided with a mounting hole, and the oil outlet adjustment block is connected to the oil outlet adjustment mounting plate by a mounting shaft passing through the mounting hole. An arc-shaped through groove 525 is also provided on the oil outlet adjustment block and located between the mounting hole and the arc-shaped oil outlet surface, and a rotating guide shaft 526 located in the middle of the arc-shaped through groove is provided on the mounting plate. The oil outlet adjustment assembly also includes a driving mechanism for driving the oil outlet adjustment block to rotate around the mounting hole. In this embodiment, the driving mechanism is an oil outlet adjustment driving motor, which is connected to the mounting shaft in a transmission manner, and the mounting shaft is connected to the oil outlet adjustment mounting plate through a bearing. In this way, the oil outlet adjustment driving motor drives the oil outlet adjustment block to rotate, and the rotation range is limited between the arc-shaped through grooves. The gap between the oil outlet hole on the arc-shaped oil outlet surface and the oiling roller is an oil covering port. The oil outlet adjustment driving mechanism drives the oil outlet adjustment block to rotate, so that the opening of the oil covering port is changed. When the oiling roller is rotating, the oiling port applies oil to the surface of the oiling roller, so that the surface of the oiling roller carries a lubricating oil layer, and the thickness of the lubricating oil layer changes with the opening of the oiling port. When the opening of the oiling port becomes larger, the oil layer on the surface of the oiling roller becomes thicker, so that the oiling roller can apply more lubricating oil to the sealing ring of the rotor bearing. When the opening of the oiling port becomes smaller, the oil layer on the surface of the oiling roller becomes thinner, so that the oiling roller can apply less lubricating oil to the sealing ring of the rotor bearing.
[0054] In addition, vertical guide columns are respectively arranged on the bottom plate of the oil coating device and at both ends of the left support plate and the right support plate, a vertical slider is slidably arranged on the guide column and the vertical slider is located above the oil outlet adjusting block, a vertical driving cylinder connected to the screw nut of the vertical slider is fixedly installed on the top of the guide column, a side wall of the vertical slider is connected to a cantilever extending toward the rotor assembly support mechanism, and a rotor shaft positioning pin is arranged vertically downward at the end of the cantilever.
[0055] Example 2: Figure 12-15 As shown, this embodiment provides a motor assembly system. The motor assembly system requires first installing the stator assembly into the housing, and then installing the rotor assembly in embodiment 1 into the stator assembly. After installation, the lead wires at the top of the stator need to be installed with a wire sheath.
[0056] In the present embodiment, a lead wire sheath installation device 600 for installing a wire sheath is provided, comprising a wire sheath installation column 601, on which a vertical fixing plate 602 is arranged, on which a vertical fixing plate is arranged, on which a vertical slide rail is arranged, on which a wire sheath vertical slider 603 is slidably arranged, on which a wire sheath installation top plate 604 is fixed to the top of the wire sheath vertical slider, on which a wire sheath installation block 605 is installed, on which two horizontally arranged wire sheath positioning clamping plates 607 are installed, the wire sheath positioning clamping plate comprising a handle connected to the wire sheath installation block and a flat plate portion extending outward, in the middle of the flat plate portion of the wire sheath clamping plate a clearance circular hole 608 is arranged, and the clearance circular hole is used to make way for part of the rotor shaft of the motor assembly. A plurality of positioning and clamping diamond holes 609 are arranged around the circular hole on the upper edge of the sheath positioning clamping plate. The two sheath positioning clamping plates are arranged in parallel and stacked up and down and are respectively slid on the sheath mounting block through the clamping plate slider 606. The two sheath positioning clamping plates are driven by power to slide toward or away from each other. When the flat plate parts of the two sheath positioning clamping plates overlap up and down, the positioning and clamping diamond holes on the upper sheath positioning clamping plate and the lower sheath positioning clamping plate overlap each other, and the lead wires can be easily inserted into the diamond holes; when the flat plate parts of the two sheath positioning clamping plates are misaligned up and down, the positioning and clamping diamond holes on the upper sheath positioning clamping plate and the lower sheath positioning clamping plate are staggered, and the lead wires therein are clamped and positioned during the staggering process.
[0057] Among them, two parallel T-shaped sliding rails 610 are horizontally arranged on the wire protection sleeve mounting block. T-shaped sliders 611 are respectively slidably arranged in the two T-shaped sliding rails. The length of the T-shaped slider is less than that of the T-shaped sliding rail. The outer top parts of the two T-shaped sliders are respectively fixedly connected to the clamping plate sliders. In this embodiment, the heights of the two clamping plate sliders are inconsistent, so that the two wire protection sleeve positioning clamping plates can be stacked up and down. The inner bottom parts of the two T-shaped sliders are both connected with L-shaped piston rods 612. The cross bar of the L-shaped piston rod extends outwards towards the outside of the clamping plate slider direction, and a disc-shaped piston 613 is arranged at the end of the cross bar. Horizontally arranged cylindrical piston cylinders 614 respectively matching the two L-shaped piston rods are arranged on the wire protection sleeve mounting block. The disc-shaped piston is located in the cylindrical piston cylinder, and a through hole for the cross bar of the L-shaped piston rod to pass through is arranged on the side wall of the cylindrical piston cylinder. Two horizontal grooves 615 for the vertical rods of the two L-shaped piston rods to horizontally slide are arranged on the wire protection sleeve mounting block. The two horizontal grooves are arranged back to back. The cylindrical piston cylinder is connected with a trachea through an air hole. By controlling the trachea, the compressed gas in the two cylindrical piston cylinders can be controlled, so as to realize the axial reciprocating movement of the L-shaped piston in the cylindrical piston cylinder, and then realize the translation of the clamping plate slider on the T-shaped sliding rail, and finally realize the overlap and dislocation of the positioning clamping diamond-shaped holes on the two wire protection sleeve positioning clamping plates.
[0058] In addition, as one implementation manner in this embodiment, the vertical slider of the wire protection sleeve also realizes the up and down reciprocating movement through a cylinder.
[0059] When the wire protection sleeve installation device in this embodiment is in use, first drive the two wire protection sleeve positioning clamping plates to approach so that the positioning clamping diamond-shaped holes overlap, and then drive the vertical slider of the wire protection sleeve to drive the two wire protection sleeve positioning clamping plates to move downwards, so that the lead enters the positioning clamping diamond-shaped hole, and then drive the two wire protection sleeve positioning clamping plates to move away so that the positioning clamping diamond-shaped holes are misaligned until the lead is clamped. In this way, the lead positioning is completed at the same time. At this time, the height of the lead only exceeds the positioning clamping diamond-shaped hole by a few millimeters. Then use a gripper to sleeved the wire protection sleeve on the lead, and drive the two wire protection sleeve positioning clamping plates to approach again so that the positioning clamping diamond-shaped holes overlap. At this time, the wire protection sleeve will move downwards and directly sleeved completely on the lead. Finally, drive the vertical slider of the wire protection sleeve to move upwards to drive the wire protection sleeve positioning clamping plate to move upwards away from the motor assembly. In this embodiment, a motor fixture is arranged below the motor assembly. The motor fixture is slidably arranged on the horizontal guide rail through a horizontal slider. The motor assembly realizes the translation on the horizontal guide rail through the fixture and the cylinder.
