Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0042] According to one aspect of the present invention, a linear motion mechanism for a linear rotary motor is provided, which can reduce the influence of elastic elements on the monitoring data of pressure sensors. The linear motion mechanism of the linear rotary motor according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0043] like Figure 1 , Figure 2 As shown, the motor housing includes a first housing 110 and a second housing 120. The first housing 110 is a slotted structure. Specifically, the first housing 110 is a slotted structure with side plates on all four sides. The second housing 120 is directly installed at the port of the first housing 110 by bolts.
[0044] The first housing 110 and the second housing 120 can also be flat plate structures. An annular side plate is provided between the first housing 110 and the second housing 120. A mounting post is provided on the side of the annular side plate. The mounting post can be provided on the inner side wall or the outer side wall of the annular side plate. The first housing 110 and the second housing 120 clamp the annular side plate, and then bolts pass through the mounting post to fix the first housing 110, the second housing 120 and the annular side plate.
[0045] The first housing 110 and the second housing 120 can be made of aluminum alloy or magnesium alloy. Under the premise of ensuring their strength and thermal conductivity, the machining accuracy of the first housing 110 and the second housing 120 can be guaranteed.
[0046] like Figure 14As shown, the motor also includes a carrier block 137 and an elastic element 171. The guide rail 134 of the linear motor module 130 is mounted on the first housing 110. The slider 133 of the linear motor module 130 is slidably mounted on the guide rail 134. The carrier block 137 is fixedly mounted on the slider 133. A connecting part 174 is fixedly mounted on the carrier block 134. One end of the elastic element 171 is connected to the first housing 110, and the other end of the elastic element 171 is fixedly connected to the connecting part 174. The elastic element is arranged parallel to the guide rail and is located between the rotary motor module and the guide rail, so that the tension of the elastic element can be closer to the guide rail and the force direction of the guide rail is located in its length direction.
[0047] The carrier block is provided with a mounting part for fixing the end of the pressure sensor. The mounting part is a slot-shaped structure opened on the carrier block and has screw holes. The pressure sensor is fixed to the mounting part by bolts. A second air passage fixing part is fixedly provided on the carrier block. A stop is provided between the second air passage fixing part and the mounting part to avoid the air passage from affecting the detection of the pressure sensor.
[0048] When the linear motor module 130 drives the rotary motor module 140 to move, the elastic element 171 provides tension to the carrier block 137 to counteract the weight of the slider 133, the carrier block 137, and the rotary motor module 140, without affecting the accuracy of the pressure sensor in detecting the pressure on the rotary motor module 140. The moving carrier 144 and the slider 133 are connected through the pressure sensor. If the elastic element 171 is connected to the moving carrier 144 and the carrier block 137, the elastic element 171 will affect the detection data of the pressure sensor. Therefore, the two ends of the elastic element 171 are fixedly connected to the first housing 110 and the carrier block 137 respectively. The elastic force of the elastic element will not act on the pressure sensor and will not affect the detection result of the pressure sensor.
[0049] Specifically, the linear motion mechanism also includes an adjusting block 172, which is mounted on the first housing 110. In this embodiment, the elastic element 171 is a spring, one end of which is fixedly connected to the adjusting block 172, and the other end of which is fixedly connected to the connecting part 174. The elastic element 171 can also be a pneumatic spring or a hydraulic damper.
[0050] Furthermore, the first housing 110 is provided with an adjustment groove 173 corresponding to the installation position of the adjustment block 172. The adjustment block 172 is installed in the adjustment groove 173, and the adjustment groove 173 is provided with screw holes. The adjustment block 172 is provided with strip-shaped screw fixing holes. By adjusting the position of the adjustment block 172 in the adjustment groove 173 and then fixing it with bolts, the tension of the spring can be adjusted to reduce the influence of spring fatigue deformation on its tension. A limit block is fixedly provided directly below the adjustment groove. The distance between the limit block and the lower end of the adjustment groove is less than the height of the adjustment block. The adjustment block is slidably set in the adjustment groove so that the adjustment block will not slide out from the lower end of the adjustment groove.
[0051] like Figure 15 As shown, two bolts are provided on the adjusting block 172, and an anti-loosening strip 176 is provided on the adjusting block 172. Two anti-loosening caps 177 are provided on the anti-loosening strip 176. When the adjusting block 172 is fixed in the designated position, the anti-loosening caps 177 are fastened to the bolts to prevent the bolts from loosening.
[0052] Further, such as Figure 16 As shown, the linear motion mechanism also includes a collision prevention block 175, which is fixedly mounted on the carrier block 137 and is coated with rubber. The collision prevention block 175 is located on the straight line of the guide rail 134. During the process of the linear motor module 130 driving the slider 133 to move, when the slider 133 moves to the limit position, the collision prevention block 175 abuts against the guide rail 134 to prevent the linear motor module 130 from exceeding the movement stroke and to provide limit protection for the linear motor module 130.
[0053] A linear rotary motor includes the linear motion mechanism described in any one of the above technical solutions.
[0054] The first housing 110 and the second housing 120 are provided with clearance portions 111 at the modules corresponding to the motors.
[0055] In this embodiment, by providing clearance portion 111 on the first housing 110 and the second housing 120 at the location corresponding to the motor module, the clearance portion 111 provides a recessed space at the housing location corresponding to the motor module. While ensuring the installation distance between the motor module and the side wall of the housing, the motor module can be closer to the first housing 110 and the second housing 120. The clearance portion 111 provides a certain installation distance for the motor module without affecting the working performance of the motor, thereby making the motor housing thinner.
[0056] Specifically, the clearance portion 111 is a groove provided on the end face inside the first housing 110 and the second housing 120;
[0057] or,
[0058] The clearance portion 111 is a hollow groove opened on the end face of the first housing 110 and the second housing 120.
[0059] Since opening slots in the shell and reducing the shell thickness would affect its strength, a reinforcing structure is provided around the clearance portion 111. In this embodiment, reinforcing ribs are provided around the clearance portion 111. The strength of the reinforcing ribs is greater than that of the shell. The thickness of the reinforcing ribs can be the same as the shell thickness, or it can be slightly greater than the shell thickness without affecting the installation of the internal modules. The material of the reinforcing ribs can be carbon fiber or glass fiber reinforced plastic, etc. Of course, a reinforcing coating, such as epoxy resin, carbon fiber cloth, ceramic coating, glass fiber reinforced plastic, metal coating, etc., can also be applied to the edge of the clearance portion 111.
[0060] The inclusion of the clearance section 111 can also reduce the weight of the housing, making the motor lighter.
[0061] like Figure 3 As shown, the first housing 110 has a recessed groove 112 on its side port. The second housing 120 has the same shape as the recessed groove 112. The second housing 120 is installed in the recessed groove 112. The first housing 110 and the second housing 120 are installed by fitting together with the recessed groove 112, which can further reduce the thickness of the housing. The surface of the recessed groove 112 is anodized or coated to improve its wear resistance and corrosion resistance. When the first housing 110 and the second housing 120 are installed, a sealing strip or sealant is provided around the recessed groove 112 to prevent external dust and water from entering the housing.
[0062] like Figure 1 , Figure 3 As shown, the end face inside the first housing 110 is machined to form a guide rail 134 mounting surface 113. The guide rail 134 of the linear motor module 130 is mounted on the guide rail 134 mounting surface 113, which simplifies the mounting plate structure of the guide rail 134 of the linear motor module 130 and further reduces the overall thickness of the motor. When machining the guide rail 134 mounting surface 113, a high-precision machine tool is used for machining, and then the guide rail 134 mounting surface 113 is ground to improve the machining accuracy and surface smoothness, making the installation of the guide rail 134 more precise.
[0063] like Figure 4 , Figure 5 As shown, the ultra-thin motor housing is used in a linear motor. The linear motor module 130 includes a stator 131, a mover 132, a slider 133, and a guide rail 134. The guide rail 134 is mounted on the mounting surface 113. The stator 131 drives the mover 132 to move linearly on the guide rail 134 via the slider 133. The linear motor module 130 is installed in the clearance portion 111 inside the first housing 110. The guide rail 134 is directly mounted on the housing, which reduces the thickness of the motor housing.
[0064] like Figure 5 As shown, the ultra-thin motor housing is used in a linear rotary motor (ZR motor). The linear rotary motor includes a linear motor module 130 and a rotary motor module 140. The linear motor module 130 is installed in the clearance portion 111 inside the first housing 110. The rotary motor module 140 is connected to the slider 133 of the linear motor module 130 through a pressure sensor 135. The rotary motor module 140 is correspondingly arranged in the clearance portion 111 inside the first housing 110. While ensuring the distance between the linear motor module 130 and the rotary motor module 140 and the inner walls of the first housing 110 and the second housing 120, the overall thickness of the housing can be reduced.
[0065] Further, such as Figure 6 As shown, a stress relief groove 114 is provided on the side of the first housing 110 near the linear motor module 130, and the side of the linear motor module 130 is in contact with the inner side of the first housing 110.
[0066] In this embodiment, the linear motor module 130 is installed in the first housing 110, and the rotary motor module 140 is installed on the slider 133 of the linear motor module 130. When the linear motor module 130 and the rotary motor module 140 are running, especially the linear motor module 130, uneven stress distribution will be generated. The stress generated at the connection point and contact surface between the linear motor and the first housing 110 is greater than that in other areas. The stress of the entire motor is concentrated on the linear motor module 130. The stress relief groove 114 is closest to the linear motor module 130. The side of the linear motor module 130 is in contact with the inner side of the first housing 110. By setting the stress relief groove 114 on the side of the first housing 110, the stress of the entire housing is more uniform, which can minimize the stress of the motor.
[0067] Furthermore, the stress relief groove 114 is located at the middle position on the outer side of the first housing 110. The stress relief groove 114 is elongated and covers at least half of the outer side of the first housing 110, providing sufficient stress relief path for the first housing 110 and making the stress relief of the first housing 110 more uniform.
[0068] Further, such as Figure 7 As shown, an arc-shaped groove 115 is provided on the inner side of the first housing 110 corresponding to the corner of the linear motor module 130. The corner of the object being installed corresponds to the arc-shaped groove. During the installation process, the linear motor module is installed, and a gap is set between the corner of the linear motor module 130 and the side of the arc-shaped groove 115 to achieve the suspended state of the corner of the linear motor module 130.
[0069] Because the arc groove 115 has a gap with the corner of the linear motor module 130, the corner stress of the linear motor module 130 is eliminated. The stress of the housing is mainly concentrated on the two sides rather than at the corner, which helps to disperse the stress. When the motor is running, the stress is more evenly distributed on the sides of the housing rather than concentrated at the corner, which helps to reduce the phenomenon of local stress concentration.
[0070] Further, such as Figure 7 As shown, the four corners inside the first housing 110 are all rounded and chamfered to reduce stress concentration at the corners of the first housing 110, making the stress distribution of the first housing 110 more uniform, improving the strength of the first housing 110, and making the linear motor module 130 and rotary motor module 140 work more stably.
[0071] Preferred, refer to Figure 7 The side of the first housing 110 that contacts the linear motor module 130 is thickened to form a stress-absorbing portion 116. Furthermore, the stress-absorbing portion 116 at least covers the side of the linear motor module 130 and / or the area outside the side. In this embodiment, the stress-absorbing portion 116 on the short side of the first housing 110 covers the linear motor module 130, and the stress-absorbing portion 116 on the long side of the first housing 110 covers the area outside the linear motor module 130.
[0072] The first housing 110, which is in contact with the linear motor module 130, has a stress-absorbing part 116 that is thickened on its side. This allows the first housing 110 to better absorb the stress of the linear motor module 130, resulting in higher structural strength between the first housing 110 and the linear motor module 130.
[0073] The stress-absorbing part 116 can also be configured to cover the entire side surface in contact with the first housing 110, which further improves the overall structural strength of the first housing 110 and can more effectively disperse the stress generated by the linear motor module 130, thus preventing the housing from deforming during operation.
[0074] Furthermore, refer to Figure 6 The first housing 110 has a mounting foot 117 extending outward from its long side. In this embodiment, the mounting foot 117 and the stress relief groove 114 are located on the same side of the first housing 110. The thickness of the mounting foot 117 is greater than the thickness of the stress absorption part 116, making the first housing 110 more stable to install. The mounting foot 117 also serves as an additional stress absorption structure. Furthermore, the mounting foot 117 and the stress relief groove 114 are located on the same plane, making the first housing 110 with the stress relief groove 114 stronger, the stress transmission more stable, and more conducive to the elimination of stress on the first housing 110.
[0075] Reference Figure 5-Figure 7The motor housing with stress relief groove 114 is used in a linear motor. The linear motor module 130 is placed in a corner of the first housing 110 near the stress relief structure. The linear motor module 130 is attached to the side of the first housing 110, and the stress generated by the first housing 110 on the linear motor module 130 is dispersed and eliminated.
[0076] Reference Figure 5-Figure 7 The motor housing with stress relief groove 114 is used in a linear rotary motor. The rotary motor module 140 is connected to the slider 133 of the linear motor module 130 through a pressure sensor 135. The stress generated by the rotary motor module 140 is transmitted to the linear motor module 130 and then to the first housing 110 to relieve the stress.
[0077] Further, such as Figure 8 , Figure 9 As shown, the side of the first housing 110 is provided with a terminal mounting groove 118 and an air path mounting hole 119. A terminal is provided on the terminal mounting groove 118, and an air path connector is provided in the air path mounting hole 119. The end face of the first housing 110 is provided with a first circuit fixing part 152 and a first air path fixing part 162. A slider is slidably provided inside the first housing 110. In this embodiment, the slider 133 of the linear motor module 130 is provided with a second circuit fixing part 153 and a second air path fixing part 163. The linear motor module drives the second circuit fixing part 153 and the second air path fixing part 163 to move up and down through the slider.
[0078] During installation, a circuit unit 150 and a pneumatic circuit unit 160 need to be installed inside the housing. The circuit unit 150 and the pneumatic circuit unit 160 respectively include a wiring 151 and a pneumatic circuit 161. The wiring 151 passes sequentially through the terminal mounting slot, the first circuit fixing part, and the second circuit fixing part. The pneumatic circuit 161 passes sequentially through the pneumatic circuit mounting hole, the first pneumatic circuit fixing part, and the second pneumatic circuit fixing part. The wiring 151 between the first circuit fixing part and the second circuit fixing part, and the pneumatic circuit 161 between the first pneumatic circuit fixing part and the second pneumatic circuit fixing part are set in a U-shape. During the process of the linear motor module 130 driving the slider 133 to move up and down, the U-shaped wiring 151 and pneumatic circuit 161 increase their stroke, avoiding the stroke of the wiring 151 and pneumatic circuit 161 from affecting the movement of the linear motor module 130. This makes the wiring 151 and pneumatic circuit 161 inside the motor distributed in an orderly manner. The stroke of the wiring 151 and pneumatic circuit 161 covers the movement range of the linear motor module 130, improving the safety of motor operation.
[0079] Furthermore, a cable management plate 155 is provided at the corner of the first housing 110 corresponding to the line 151. The material of the cable management plate 155 can be the same as that of the first housing 110. The cable management plate 155 is integrally formed with the first housing 110, making the cable management plate 155 structurally stronger. The line 151 is limited and bent by the cable management plate 155 and then installed in the first circuit fixing part 152. The line 151 is located between the cable management plate 155 and the inner side wall of the first housing 110, which limits the line 151 and makes the wiring of the line 151 in the first housing 110 neater. After the second housing 120 and the first housing 110 are installed, the second housing 120 seals the upper port of the cable management plate 155 to prevent the line 151 from detaching from the cable management plate 155.
[0080] The cable management board 155 can also be configured as a detachable structure, and the cable management board 155 can be connected to the first housing 110 by bolts, clips or adhesives to adapt to the layout requirements of different lines 151 and facilitate adjustment. The cable management board 155 can be made of insulating material to avoid direct contact between the lines 151 and the metal housing, thereby improving safety.
[0081] Line 151 is a ribbon cable, and line 151 is connected to terminal mounting slot 118 and second circuit fixing part 153 through ribbon cable connector 156;
[0082] Furthermore, refer to Figure 8 , Figure 9 A first air passage diverter 164 is installed in the air passage mounting hole 119, the first air passage fixing part 162 is the second air passage diverter, and the second air passage fixing part 163 is the third air passage diverter.
[0083] Specifically, the first air passage diverter 164 has a 90° turn, the second air passage diverter has a 0° turn, and the third air passage diverter has a 145° turn. The air passage diverter 161 is a mature application of existing technology and will not be described in detail in this patent application. The air passage 161 is arranged close to the side wall of the first housing 110 after a 90° turn through the first air passage diverter 164. The air passage 161 is bent 90° inside the first housing 110 and then connected to the second air passage diverter. It then extends in the opposite direction and is bent into a U-shape to connect with the third air passage diverter. This realizes that the air passage 161 has a U-shaped structure with a range of motion inside the first housing 110. The air passage 161 can be adjusted as the slider 133 moves up and down.
[0084] A motor housing with a wire management structure is used in a linear motor. The linear motor includes a circuit unit 150 and a linear motor module 130 installed in a first housing 110. The wires 151 of the circuit unit 150 are introduced into the first housing 110 through a terminal mounting slot 118. The middle position of the wires 151 is limited in a first circuit fixing part 152, and the end of the wires 151 is fixedly set on a second circuit fixing part 153. The wires 151 between the first circuit fixing part 152 and the second circuit fixing part 153 are arranged in a U-shape. After the wires 151 are arranged in a U-shape, they are connected to the linear motor module 130.
[0085] During the up-and-down movement of the slider 133 on the mover 132 of the linear motor module 130, the U-shaped arrangement of the circuit 151 provides redundant length for the up-and-down movement of the slider 133, reducing the vertical height of the housing. At the same time, it avoids the arrangement of the circuit 151 and the air passage 161 from interfering with the movement of the linear motor module 130, making the circuit 151 and air passage 161 inside the motor well-organized, covering the movement range of the linear motor module 130, and improving the safety of motor operation.
[0086] A motor housing with a cable management structure is used in a linear rotary motor. It includes a linear motor module 130, a rotary motor module 140, a circuit unit 150, and a pneumatic circuit unit 160. The linear motor module 130 and the rotary motor module 140 are installed in the cable management structure motor housing. The wiring 151 of the circuit unit 150 is introduced into the first housing 110 through a terminal mounting slot 118. The middle position of the wiring 151 is confined in a first circuit fixing part 152, and the end of the wiring 151 is fixedly disposed on a second circuit fixing part 153. The first circuit fixing part 152 and the second circuit fixing part 153 are connected... The circuit 151 between the circuit units is U-shaped. After the circuit 151 is arranged in a U-shape, it is connected to the linear motor module 130 and the rotary motor module 140. The air passage 161 of the air passage unit 160 is introduced into the first housing 110 through the air passage mounting hole 119. The middle position of the air passage 161 is fixed on the first air passage fixing part 162, and the end of the air passage 161 is fixed on the second air passage fixing part 163. The circuit 151 between the first circuit fixing part 152 and the second circuit fixing part 153 and the air passage 161 between the first air passage fixing part 162 and the second air passage fixing part 163 are U-shaped.
[0087] To avoid the layout of the wiring 151 and the air passage 161 interfering with the movement of the linear motor module 130, the wiring 151 and the air passage 161 inside the motor are distributed in an orderly manner, and the stroke covers the movement range of the linear motor module 130, thereby improving the safety of motor operation.
[0088] Further, such as Figures 8-10As shown, the first circuit fixing part 152 includes a base 1521 and a cable management part 1522. The base 1521 is detachably installed on the inner end face of the first housing 110. Multiple cable management parts 1522 are arranged on the base 1521. The gap between the cable management parts 1522 is set as a cable management groove 1523. The circuit 151 is arranged in the cable management groove 1523. Specifically, there are three cable management grooves 1523.
[0089] like Figures 8-11 As shown, the motor housing contains a linear motor module 130, a rotary motor module 140, a circuit unit 150, an air circuit unit 160, and a grating ruler 154. The grating ruler 154 is mounted on the side of the rotary motor module 140. The wiring of the linear motor module 130, the rotary motor module 140, and the grating ruler 154 is arranged in the corresponding cable management grooves 1523. The wiring is not fixedly connected to the cable management grooves 1523. This design ensures that the wiring of the three components does not interfere with each other, increases the degree of freedom of the wiring, reduces bending of the wiring during operation, and improves the service life of the wiring.
[0090] The uppermost end of the cable management channel 1523 is on the same plane as the port of the first housing 110. When the second housing 120 is installed at the port of the first housing 110, the second housing 120 just blocks the opening of the cable management channel 1523 to prevent the cable from coming off the cable management channel 1523.
[0091] like Figure 1 , Figures 8-11 As shown, a mounting base 157 is provided on the inner end face of the first housing 110 at the position corresponding to the first circuit fixing part 152. The base 1521 is fixed on the mounting base 157 by bolts, which facilitates the assembly and disassembly of the first circuit fixing part 152.
[0092] The cable management grooves 1523 have different depths, and the number of second circuit fixing parts 153 is the same as that of cable management grooves 1523. By staggering the cable arrangement of the linear motor module 130, rotary motor module 140 and grating ruler 154 in the cable management grooves 1523 of corresponding depths, and then installing them on the corresponding second circuit fixing parts 153, the neat arrangement of the cables is achieved.
[0093] Further, such as Figure 12 As shown, a limit strip 142 is detachably provided on the rotary motor module 140. The limit strip 142 has an elongated hole 143. The wiring of the second circuit fixing part 153 passes through the elongated hole 143 and connects to the rotary motor module 140. The elongated hole 143 limits the wiring of the rotary motor module 140, making the wiring inside the housing more neat and preventing the wiring from contacting the external moving mechanism when the linear motor module 130 and the rotary motor module 140 are working, thus ensuring the stable operation of the rotary motor module 140.
[0094] Specifically, a protective ring made of plastic or rubber is provided on the inner side of the elongated hole 143 to prevent the cable from rubbing against the limit strip 142 and causing wear when the cable shakes.
[0095] Further, such as Figure 12 , Figure 13 As shown, a moving component 144 is detachably and fixedly mounted on the rotary motor module 140. An air passage 145 is provided on the side of the moving component 144. The moving component 144 is fixedly connected to the slider 133 through a pressure sensor 135. The pressure sensor 135 passes over the moving component 144 and a protective plate 136 is fixedly mounted at the air passage 145. An air connector is fixedly mounted on the moving component 144. An air passage 161 led out from the third air passage deflector bypasses the air passage 145 and connects to the air connector. The protective plate 136 protects the air passage 161. At the same time, the air passage 161 is set in the air passage 145 to prevent the air passage 161 from protruding from the moving component 144 and to prevent the air passage 161 from rubbing against the side wall of the housing, thereby improving the safety of the system air passage 161 and avoiding damage to the air passage 161.
[0096] The air passage 145 can be two straight passages provided on the moving carrier 144. The air passage 161 enters from one of the straight passages and then exits from the outside of the moving carrier 144 to the other straight passage.
[0097] The air passage 145 can also be a complete passage opened on the moving carrier 144, which is arranged in a U-shape on the side of the moving carrier 144.
[0098] Of course, the above two air passage 145 can be set inside the moving component 144 or open on the surface of the moving component 144.
[0099] Further, such as Figures 17-20 The output end of the rotary motor module 140 shown is fixedly equipped with a bushing 180. Specifically, the bushing 180 is mounted on the moving carrier 144. The output shaft 141 of the rotary motor module 140 passes through the bushing 180. A positioning plane 181 is provided on the outer wall of the bushing 180, and a positioning groove 182 is formed on the positioning plane 181. During testing, the detection head of the measuring instrument can be set on the positioning plane 181 or in the positioning groove 182 for distance detection. This provides different detection benchmarks for the measuring instrument, thereby improving the detection accuracy through multiple measurements of different detection benchmarks, and making the bushing 180 more accurately installed. Furthermore, the bushing allows the output shaft of the rotary motor module to be designed to be longer, and the bushing provides protection and limit for the output shaft of the rotary motor module.
[0100] The positioning groove 182 can be a recess for positioning, or it can be a long groove or a cross-shaped groove. It can limit the detection head of the measuring instrument and prevent measurement errors caused by the position deviation of the measuring instrument during the measurement process.
[0101] Specifically, there are four positioning planes 181, which correspond to the four faces of the housing respectively. The distance between the bushing 180 and the four faces of the housing is measured by dial gauge to improve the installation accuracy of the bushing 180.
[0102] The mounting surface of the bushing 180 is provided with a boss 183, and the mounting surface of the moving carrier 144 is provided with a corresponding groove. When installing the bushing 180, the boss 183 is inserted into the groove on the moving carrier 144 to achieve positioning and improve installation accuracy.
[0103] The positioning plane 181 is marked with scale lines to facilitate the selection of accurate measurement positions and improve measurement accuracy.
[0104] like Figure 21 As shown, the side of the bushing 180 is provided with a sliding groove 186 along its axial direction. A wedge block 187 is slidably disposed in the sliding groove 186. By adjusting the position of the wedge block 187, an operating hole 1101 is opened on the side of the first housing 110. The bushing 180 passes through the operating hole 1101, so that the wedge block 187 cooperates with the operating hole 1101, thereby adjusting the coaxiality of the bushing 180 and the rotary motor module 140, so that the bushing 180 has higher installation accuracy.
[0105] Specifically, the slide groove 186 is set on the center line of the positioning plane 181. By adjusting the position of the wedge block 187, the distance between the positioning plane 181 and the side of the housing can be directly adjusted, which is convenient.
[0106] The mounting surface of the bushing 180 is provided with a sealing gasket 184. The bushing 180 is mounted on the moving component 144 to prevent air leakage between the bushing 180 and the moving component 144.
[0107] The bushing 180 is provided with a first sealing ring 185 inside, which is used to seal the output shaft 141 of the rotary motor module 140 and the bushing 180 to prevent air leakage between the bushing 180 and the output shaft 141 of the rotary motor module 140.
[0108] like Figure 5 , Figures 17-21As shown, bushing 180 is used in a rotary motor. Motion carrier 144 is mounted on rotary motor module 140, and bushing 180 is mounted on motion carrier 144. The output shaft 141 of rotary motor module 140 passes through motion carrier 144 and bushing 180. A second sealing ring 188 is provided inside motion carrier 144. A vent hole 1411 is provided on the side of output shaft 141 of rotary motor module 140, located between first sealing ring 185 and second sealing ring 188. A cavity 189 is formed between output shaft 141 of rotary motor module 140, motion carrier 144, and bushing 180. First sealing ring 185 and second sealing ring 188 are located at both ends of cavity 189. An air passage 1412 is axially arranged on the output shaft 141 of the block 140. An air connector is fixedly arranged on the moving carrier 144 to connect the air connector, the vent 1411 and the air passage 1412. A suction cup is installed at the end of the output shaft 141 of the rotary motor module 140 to hold the product. By setting the moving carrier 144 and the bushing 180, the length of the output shaft 141 of the rotary motor module 140 can be greatly increased, realizing remote operation of the suction cup. The cavity 189 can provide a channel for gas flow between the air connector and the vent 1411, and can also reduce the contact area between the output shaft 141 of the rotary motor module 140 and the moving carrier 144 and the bushing 180, reduce wear, and extend the service life of the rotary motor module 140.
[0109] like Figure 5 , Figures 17-21 As shown, the bushing 180 is used in a linear rotary motor, which includes a housing consisting of a first housing 110 and a second housing 120. The linear motor module 130 is installed in the first housing 110. The rotary motor module 140 is installed on the slider 133 of the linear motor module 130 via a pressure sensor. The motion carrier 144 is installed on the rotary motor module 140, and the bushing 180 is installed on the motion carrier 144. The output shaft 141 of the rotary motor module 140 passes through the motion carrier 144 and the bushing 180.
