Description

Technical Field

[0001] The present invention relates to the field of motor processing, and more specifically, to a vacuum motor production device and a vacuum motor. Background Art

[0002] A vacuum motor is a motor that works in a vacuum environment. It needs to have characteristics such as high temperature resistance and low gas outflow rate to meet the needs of specific application environments.

[0003] When the motor is exposed to a vacuum environment, the air and water vapor in the motor need a certain amount of time to evaporate and escape. Since the escape process is relatively slow, the vacuum environment will be continuously disturbed and damaged during this period, resulting in the vacuum state failing to reach or being difficult to maintain at a high vacuum level. This slow escape process will interfere with the vacuum environment.

[0004] In the prior art, moisture and air inside the vacuum motor are extracted during the production process, and the inside of the motor is kept in a sealed state, so as to prevent the motor from interfering with the vacuum environment when in use. However, when the processing is completed and a new motor is replaced for processing, the operating box needs to be opened, and outside air will enter it for drying. However, in the prior art, absorbents are usually used to absorb moisture, which has low working efficiency and poor dehumidification effect.

[0005] To this end, a vacuum motor production device and a vacuum motor are proposed. Summary of the invention

[0006] In view of the problems existing in the prior art, the object of the present invention is to provide a vacuum motor production device and a vacuum motor, which can improve the drying effect on the inside of the motor.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A vacuum motor production device comprises a box body, a casing and an end cover;

[0009] A fixed sleeve and a guide rail are fixedly installed in the box, a moving sleeve is installed on the output end of the guide rail, the adjacent ends of the fixed sleeve and the moving sleeve are open, and the end cover of the motor to be assembled is placed in the fixed sleeve, so that the casing and the end cover can be driven closer to or farther away from each other through the output end of the guide rail.

[0010] It also includes a storage box, in which a desiccant is contained; the box body is provided with a circulation mechanism for circulating the gas in the storage box and the box body;

[0011] A cavity is provided on the box body, and a heating wire is provided in the cavity. The heating wire is used to heat the air in the box body, so that the moisture in each component in the box body is converted into water vapor and suspended in the air;

[0012] A cavity is provided on the fixed sleeve, and air holes are obliquely provided on the side wall of the cavity, and an air supply mechanism for supplying air to the cavity is provided on the box body; when the air supply mechanism provides high-pressure gas to the cavity, the high-pressure gas in the cavity is discharged through the air holes; since the exhaust direction of the air holes remains unchanged, the contact position of the high-temperature gas discharged from the air holes with the inside of the casing gradually changes during the process of the guide rail driving the casing to approach the end cover, thereby increasing the contact probability of the high-temperature gas with various parts inside the casing, and improving the heating and evaporation effect of the moisture on the surface of each component in the casing;

[0013] A heat pipe that runs through the storage box is fixedly inserted on the storage box. Therefore, when water vapor flows into the storage box, part of the high-temperature water vapor is absorbed by the desiccant, and part of the high-temperature water vapor contacts the heat pipe. The water vapor is cooled and liquefied, and the liquefied water droplets contact the desiccant. The desiccant absorbs the water droplets, further improving the dehumidification effect on the gas discharged from the storage box. Both ends of the heat pipe are open, so the air in the heat pipe can automatically float up after being heated, which ensures that the heat pipe can maintain a low temperature.

[0014] A sleeve is sleeved on the heat conducting pipe, a fixing rod is provided between the sleeve and the inner wall of the storage box, the sleeve is rotatably inserted on the fixing rod, so that both ends of the sleeve are not in contact with the storage box, an auger is fixedly installed on the inner wall of the sleeve, and the auger is movably sleeved on the outer wall of the heat conducting pipe, so the auger can rotate; and a driving mechanism for driving the sleeve to rotate is provided on the box body; in the process of driving the sleeve to rotate by the driving mechanism, under the action of the auger, the desiccant attached to the outer wall of the heat conducting pipe that has absorbed water droplets is promptly transferred upward, and at the same time, the desiccant located outside the sleeve falls downward and is driven by the auger to move upward to the surface of the heat conducting pipe, thereby increasing the contact probability between the dry desiccant and the condensed water, improving the absorption effect of water droplets, and further improving the drying effect of the air;

[0015] An electric screwdriver is arranged in the fixed sleeve, a screw is rotatably installed on the end cover, and a screw hole matching with the screw is opened on the casing; therefore, when the end cover and the casing are tightly fitted together, the electric screwdriver is aligned with the screw, and the screw will be screwed into the screw hole, thereby realizing the assembly of the end cover and the casing in a dry environment and reducing the moisture content in the casing.

[0016] Furthermore, the sleeve is made of a filter screen to ensure that the high-temperature water vapor entering the storage box can contact the heat transfer tube, and a sieve plate covering the surface of the input end of the circulating pump is fixedly installed on the inner wall of the storage box, thereby preventing the desiccant from entering the circulating pump and preventing the circulating pump from being damaged.

[0017] Further, the circulation mechanism includes a circulation pump, an air intake valve whose input end is connected to the box body is embedded on the side wall of the storage box, the air intake valve is a pressure valve, and the gas in the box body passes through the air intake valve into the storage box, the input end of the circulation pump is connected to the storage box, and the output end of the circulation pump extends into the cavity;

[0018] The air supply mechanism includes a conduit fixedly inserted on the side wall of the cavity, and the conduit extends into the cavity. During the operation of the circulating pump, the circulating pump draws air from the storage box and discharges the gas into the cavity. The gas in the cavity is discharged into the box through the conduit, thereby realizing the circulation of gas in the storage box and the box and supplying air to the cavity.

[0019] Further, the driving mechanism includes a socket provided on the fixed rod, the sleeve is rotatably inserted in the socket, an annular groove is provided on the side wall of the socket, a ratchet is fixedly sleeved on the outer wall of the sleeve, a mounting sleeve is rotatably installed in the annular groove, a clamping rod cooperating with the ratchet is rotatably installed on the inner wall of the mounting sleeve, and a spring is fixedly installed between the clamping rod and the mounting sleeve;

[0020] During the clockwise rotation of the mounting sleeve, under the action of the spring, the mounting sleeve drives the clamping rod to be inserted into the tooth groove of the ratchet wheel, thereby pushing the ratchet wheel to rotate together, and at this time, the housing drives the sleeve to rotate; and the mounting sleeve, the spring, the clamping rod, and the ratchet wheel cooperate with each other to make the ratchet wheel rotate unidirectionally, which is the prior art and will not be described in detail;

[0021] A spring is installed between the side wall of the annular groove and the mounting sleeve; the spring accumulates force during the rotation of the mounting sleeve;

[0022] A mounting tube extending into the box body is fixedly inserted on the side wall of the annular groove, and a connecting rope is arranged in the mounting tube, and two ends of the connecting rope are respectively fixedly connected to the output end of the guide rail and the outer side wall of the mounting sleeve;

[0023] When the casing and the end cover are placed in the initial state, the output end of the guide rail is located at the end of the guide rail close to the storage box, and the connecting rope is wound on the sleeve at this time; in the process of the guide rail output end driving the moving sleeve to move, the guide rail output end is away from the storage box, and the connecting rope pulls the installation sleeve to rotate; when the guide rail output end is reset again, the guide rail output end no longer applies tension to the connecting rope, the mainspring recovers and drives the installation sleeve to reverse, and the clamping rod is pulled out of the tooth groove of the ratchet wheel, and the sleeve is in a stationary state; therefore, with the cooperation of the ratchet wheel, the push rod and the spring, the sleeve can drive the auger to rotate in one direction, which ensures that the saturated desiccant around the heat pipe can be transferred upward in time.

[0024] Furthermore, a gear is fixedly mounted on the sleeve, and the gears on two adjacent sleeves are meshed, so when one of the sleeves rotates, all the sleeves can be driven to rotate through the meshed gears, thereby ensuring that all the sleeves can drive the auger to rotate; and for the desiccant that will agglomerate after absorbing water, when the desiccant overflows from the top of the sleeve, the desiccant will fall onto the surface of the gear, and then fall downward along the side wall of the gear. During the rotation of the gear, the agglomerated desiccant that falls downward along the side wall of the gear is impacted, so that the desiccant can be crushed, and the agglomerated desiccant can be crushed at the meshing point of the two gears;

[0025] When the agglomerated desiccant is broken, the unsaturated desiccant inside the agglomerated desiccant will be exposed to the outside, increasing the probability of the unsaturated desiccant contacting with humid air, thereby improving the utilization rate of the desiccant and playing a role in improving the drying effect of the gas.

[0026] Furthermore, impact rods are evenly installed on the side wall of the sleeve, and the impact rods are located above the gear.

[0027] The sleeve drives the impact rod to impact the saturated desiccant, which can initially crush the desiccant, thereby preventing the gear from being stuck and unable to rotate, thereby ensuring that each sleeve can rotate.

[0028] Furthermore, an elastic rope is fixedly installed in the air hole, and a spoiler block is fixedly installed on the elastic rope. Therefore, during the exhaust process of the air hole, the airflow impacts the spoiler block and the spoiler block shakes, thereby changing the flow direction of the gas discharged from the air hole, increasing the probability of the gas discharged from the air hole entering the gaps between the components in the casing, and improving the drying effect of the components in the casing.

[0029] Furthermore, an air pump is fixedly installed on the box body, and the output end of the air pump cooperates with the heat conduction pipe, and the input end of the air pump extends into the box body. Therefore, after the end cover and the casing are placed in the specified positions, the air pump is started, and part of the air in the box body is extracted by the air pump, thereby reducing the content of humid air in the box body. Therefore, in the process of assembling the motor, the workload of the desiccant is reduced, and the internal components of the motor can be dried in time, which plays a role in improving work efficiency.

[0030] A vacuum motor, suitable for the above vacuum motor production equipment;

[0031] It includes an annular baffle and an annular mounting plate, an elastic pad is fixedly mounted on the mounting plate, the mounting plate is fixedly mounted on the inner wall of the end cover, and the baffle is fixedly mounted on the inner wall of the casing; when the casing and the end cover are installed together, the baffle squeezes the elastic pad, and at this time the elastic pad is deformed and in close contact with the mounting plate and the baffle, thereby being able to seal the gap between the end cover and the casing to prevent the inside of the casing from communicating with the outside.

[0032] Furthermore, an air cavity is opened on the elastic pad, and nitrogen is filled in the air cavity; during operation, heat is generated inside the motor, and the heat is transferred to the nitrogen through heat exchange, so that the nitrogen in the air cavity expands, thereby driving the elastic pad to expand, so that the elastic pad is in close contact with the baffle, thereby improving the sealing between the end cover and the casing, and preventing moisture leakage inside the motor.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] (1) This solution can complete the assembly of the motor in a closed box by providing a fixed sleeve, a movable sleeve, and a guide rail. By providing an air pump, part of the humid gas in the closed box is extracted, thereby reducing the humid gas content inside the assembled motor. By providing a storage box, a desiccant, and a circulating pump, the dehumidification effect of each component inside the motor can be further improved during the assembly process.

[0035] (2) This solution can heat the moisture in the components inside the motor by setting up electric heating wires, so that the moisture evaporates into the air. Under the action of the circulating pump, the water vapor comes into contact with the desiccant, thereby further reducing the water content inside the motor during the production process;

[0036] (3) This scheme is to set up heat pipes and auger; the small water droplets that are liquefied by cooling can be absorbed by the desiccant, and the rotating auger can transfer the water-saturated desiccant in time, and transfer the desiccant that is not in direct contact with the small water droplets to the surface of the heat pipe, thereby improving the absorption effect of the small water droplets and shortening the time required for drying the air. Therefore, the assembly can be completed quickly, which plays a role in improving work efficiency;

[0037] (4) This scheme is provided with gears and impact rods. When using desiccant such as calcium chloride which absorbs water and easily agglomerates, the gears and impact rods can break up the agglomerated desiccant, and then discharge the desiccant that has not reached the saturated state and is wrapped in the agglomerated desiccant, thereby improving the utilization rate of the desiccant.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0048] Example 1: Please refer to Figures 1 to 7 , a vacuum motor production equipment, comprising a box body 1, a casing 2 and an end cover 3;

[0049] A fixed sleeve 4 and a guide rail 5 are fixedly installed in the box body 1, and a movable sleeve 6 is installed on the output end of the guide rail 5. The adjacent ends of the fixed sleeve 4 and the movable sleeve 6 are both open, and the end cover 3 of the motor to be assembled is placed in the fixed sleeve 4, so that the housing 2 and the end cover 3 can be driven to move closer to or away from each other through the output end of the guide rail 5.

[0050] It also includes a storage box 7, which contains a desiccant; the box body 1 is provided with a circulation mechanism for circulating the gas in the storage box 7 and the box body 1;

[0051] The box body 1 is provided with a cavity, and a heating wire 8 is provided in the cavity. The heating wire 8 is used to heat the air in the box body 1, so that the moisture in each component in the box body 1 is converted into a water vapor state and suspended in the air;

[0052] A cavity 9 is provided on the fixed sleeve 4, and an air hole 10 is obliquely provided on the side wall of the cavity 9. An air supply mechanism for supplying air to the cavity 9 is provided on the box body 1. When the air supply mechanism provides high-pressure gas to the cavity 9, the high-pressure gas in the cavity 9 is discharged through the air hole 10. Since the exhaust direction of the air hole 10 remains unchanged, the contact position of the high-temperature gas discharged from the air hole 10 with the inside of the casing 2 gradually changes during the process in which the guide rail 5 drives the casing 2 to approach the end cover 3, thereby increasing the contact probability of the high-temperature gas with various parts inside the casing 2, and improving the heating and evaporation effect of the moisture on the surface of each component in the casing 2.

[0053] A heat-conducting pipe 11 that penetrates the storage box 7 is fixedly inserted on the storage box 7. Therefore, when water vapor flows into the storage box 7, part of the high-temperature water vapor is absorbed by the desiccant, and part of the high-temperature water vapor contacts the heat-conducting pipe 11. The water vapor is cooled and liquefied, and the liquefied water droplets contact the desiccant. The desiccant absorbs the water droplets, further improving the dehumidification effect on the gas discharged from the storage box 7; both ends of the heat-conducting pipe 11 are open, so the air in the heat-conducting pipe 11 can automatically float up after being heated, which ensures that the heat-conducting pipe 11 can maintain a low temperature state.

[0054] A sleeve 12 is sleeved on the heat conducting pipe 11, and a fixing rod 13 is provided between the sleeve 12 and the inner wall of the storage box 7. The sleeve 12 is rotatably inserted on the fixing rod 13, so that both ends of the sleeve 12 are not in contact with the storage box 7, and an auger 14 is fixedly installed on the inner wall of the sleeve 12, and the auger 14 is movably sleeved on the outer wall of the heat conducting pipe 11, so the auger 14 can rotate; and a driving mechanism for driving the sleeve 12 to rotate is provided on the box body 1; in the process of driving the sleeve 12 to rotate by the driving mechanism, under the action of the auger 14, the desiccant attached to the outer wall of the heat conducting pipe 11 that has absorbed water droplets is transferred upward in time, and at the same time, the desiccant located outside the sleeve 12 falls downward and is driven by the auger 14 to move upward to the surface of the heat conducting pipe 11, thereby increasing the probability of the dry desiccant contacting with condensed water, improving the absorption effect of water droplets, and further improving the drying effect of air.

[0055] like Figure 2 As shown, the sleeve 12 is made of a filter screen to ensure that the high-temperature water vapor entering the storage box 7 can contact the heat pipe 11, and a sieve plate 18 covering the input end surface of the circulation pump 15 is fixedly installed on the inner wall of the storage box 7, thereby preventing the desiccant from entering the circulation pump 15, thereby ensuring that the circulation pump 15 is protected from damage.

[0056] like Figure 2As shown, the circulation mechanism includes a circulation pump 15, and an air intake valve 16 whose input end is connected to the box body 1 is embedded on the side wall of the storage box 7. The air intake valve 16 is a pressure valve, and the gas in the box body 1 passes through the air intake valve 16 to enter the storage box 7. The input end of the circulation pump 15 is connected to the storage box 7, and the output end of the circulation pump 15 extends into the cavity;

[0057] The air supply mechanism includes a conduit 17 fixedly inserted on the side wall of the cavity, and the conduit 17 extends into the cavity 9. During the operation of the circulation pump 15, the circulation pump 15 draws air from the storage box 7 and discharges the gas into the cavity. The gas in the cavity is discharged into the box 1 through the conduit 17, thereby realizing the circulation of gas in the storage box 7 and the box 1 and the function of supplying air to the cavity 9.

[0058] like Figure 5 As shown, the driving mechanism includes a socket provided on a fixed rod 13, a sleeve 12 is rotatably inserted in the socket, an annular groove is provided on the side wall of the socket, a ratchet 19 is fixedly sleeved on the outer wall of the sleeve 12, a mounting sleeve 20 is rotatably installed in the annular groove, a clamping rod 21 cooperating with the ratchet 19 is rotatably installed on the inner wall of the mounting sleeve 20, and a spring 22 is fixedly installed between the clamping rod 21 and the mounting sleeve 20;

[0059] During the clockwise rotation of the mounting sleeve 20, under the action of the spring 22, the mounting sleeve 20 drives the clamping rod 21 to be inserted into the tooth groove of the ratchet 19, so as to push the ratchet 19 to rotate together, and at this time, the housing 2 drives the sleeve 12 to rotate; and the mounting sleeve 20, the spring 22, the clamping rod 21, and the ratchet 19 cooperate with each other to make the ratchet 19 rotate in one direction, which is the prior art and will not be described in detail;

[0060] A spring 23 is installed between the side wall of the annular groove and the mounting sleeve 20; the spring 23 accumulates force during the rotation of the mounting sleeve 20;

[0061] A mounting tube 24 extending into the box body 1 is fixedly inserted on the side wall of the annular groove, and a connecting rope 25 is arranged in the mounting tube 24. The two ends of the connecting rope 25 are respectively fixedly connected to the output end of the guide rail 5 and the outer side wall of the mounting sleeve 20;

[0062] When the casing 2 and the end cover 3 are placed in the initial state, the output end of the guide rail 5 is located at the end of the guide rail 5 close to the storage box 7, and the connecting rope 25 is wound on the sleeve 12; in the process of the output end of the guide rail 5 driving the movable sleeve 6 to move, the output end of the guide rail 5 is away from the storage box 7, and the connecting rope 25 pulls the installation sleeve 20 to rotate; when the output end of the guide rail 5 is reset again, the output end of the guide rail 5 no longer applies tension to the connecting rope 25, the mainspring 23 recovers and drives the installation sleeve 20 to reverse, and the clamping rod 21 is pulled out of the tooth groove of the ratchet 19, and the sleeve 12 is in a stationary state; therefore, with the cooperation of the ratchet 19, the push rod and the spring 22, the sleeve 12 can drive the auger 14 to rotate unidirectionally, which ensures that the saturated desiccant around the heat pipe 11 can be transferred upward in time.

[0063] like Figure 7 As shown, a gear 26 is fixedly sleeved on the sleeve 12, and the gears 26 on two adjacent sleeves 12 are meshed, so when one of the sleeves 12 rotates, all the sleeves 12 can be driven to rotate through the meshed gears 26, which ensures that all the sleeves 12 can drive the auger 14 to rotate; and for the desiccant that will agglomerate after absorbing water, when the desiccant overflows from the top of the sleeve 12, the desiccant will fall onto the surface of the gear 26, and then fall downward along the side wall of the gear 26. During the rotation of the gear 26, the agglomerated desiccant that falls downward along the side wall of the gear 26 is impacted, so that the desiccant can be crushed, and the agglomerated desiccant can be crushed at the meshing point of the two gears 26;

[0064] When the agglomerated desiccant is broken, the unsaturated desiccant inside the agglomerated desiccant will be exposed to the outside, increasing the probability of the unsaturated desiccant contacting with humid air, thereby improving the utilization rate of the desiccant and playing a role in improving the drying effect of the gas.

[0065] like Figure 2 As shown, impact rods 35 are evenly installed on the side wall of the sleeve 12 , the impact rods 35 are located above the gear 26 , and the length of the impact rods 35 is less than the distance between the outer diameter and the inner diameter of the gear 26 .

[0066] The sleeve 12 drives the impact rod 35 to impact the saturated desiccant, so as to preliminarily crush the desiccant, thereby preventing the gear 26 from being stuck and unable to rotate, thereby ensuring that each sleeve 12 can rotate.

[0067] like Figure 3As shown, an elastic rope 27 is fixedly installed in the air hole 10, and a spoiler block 28 is fixedly installed on the elastic rope 27. Therefore, during the exhaust process of the air hole 10, the airflow impacts the spoiler block 28, and the spoiler block 28 shakes, thereby changing the flow direction of the gas discharged from the air hole 10, increasing the probability of the gas discharged from the air hole 10 entering the gaps between the components in the casing 2, and improving the drying effect of the components in the casing 2.

[0068] like Figure 2 As shown, an air pump 29 is fixedly installed on the box body 1, and the output end of the air pump 29 cooperates with the heat conducting pipe 11, and the input end of the air pump 29 extends into the box body 1. Therefore, after the end cover 3 and the housing 2 are placed in the specified position, the air pump 29 is started, and part of the air in the box body 1 is extracted through the air pump 29, thereby reducing the content of humid air in the box body 1. Therefore, in the process of assembling the motor, the workload of the desiccant is reduced, and the internal components of the motor can be dried in time, which plays a role in improving work efficiency;

[0069] A branch pipe 34 corresponding to the heat pipe 11 is provided on the output end of the air pump 29, and the branch pipe 34 is aligned with the corresponding heat pipe 11, so that the gas discharged from the output end of the air pump 29 can be discharged through the branch pipe 34, and the gas discharged from the branch pipe 34 impacts the inner wall of the heat pipe 11, and then the gas in the heat pipe 11 can be replaced after completing a work, which plays a role in cooling the heat pipe 11.

[0070] like Figure 2 , Figure 3 and Figure 4 As shown, a vacuum motor is suitable for the above vacuum motor production equipment;

[0071] It includes an annular baffle 30 and an annular mounting plate 31, an elastic pad 32 is fixedly mounted on the mounting plate 31, the mounting plate 31 is fixedly mounted on the inner wall of the end cover 3, and the baffle 30 is fixedly mounted on the inner wall of the casing 2; when the casing 2 and the end cover 3 are installed together, the baffle 30 squeezes the elastic pad 32, at which time the elastic pad 32 is deformed and in close contact with the mounting plate 31 and the baffle 30, thereby being able to seal the gap between the end cover 3 and the casing 2 to prevent the inside of the casing 2 from communicating with the outside.

[0072] like Figure 4 As shown, an air cavity 33 is opened on the elastic pad 32, and nitrogen is filled in the air cavity 33; during operation, heat is generated inside the motor, and the heat is transferred to the nitrogen through heat exchange, so the nitrogen in the air cavity 33 expands, thereby driving the elastic pad 32 to expand, so that the elastic pad 32 is in close contact with the baffle 30, thereby improving the sealing between the end cover 3 and the casing 2, and preventing moisture leakage inside the motor.

[0073] like Figure 2As shown, an electric screwdriver is provided in the fixed sleeve 4, a screw is rotatably installed on the end cover 3, and a screw hole matching the screw is opened on the casing 2; therefore, when the end cover 3 and the casing 2 are tightly fitted together, the electric screwdriver is aligned with the screw, and the screw can be screwed into the screw hole by starting the electric screwdriver, thereby completing the assembly of the end cover 3 and the casing 2 in a dry environment and reducing the moisture content in the casing 2.

[0074] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
