Description

Technical Field

[0001] The present invention relates to the technical field of motor housing jigs, and specifically to a motor housing processing jig and a method for using the jig. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. The motor housing is generally of a cylindrical structure, and then a flange for butt joint fixation is installed at the end. The motor housing is a protective device for the motor. When performing precision finishing polishing on the motor housing, it is necessary to clamp the motor housing with a jig.

[0003] When performing precision finishing polishing on the motor housing, it is usually necessary to process both sides of the housing. Generally, after the ordinary machine tool for polishing finishes processing one side, it is also necessary for workers to manually take out the housing, turn it over, and reinstall it on the machine tool. This process not only requires extra time but also increases the production cycle and reduces production efficiency. In view of the above problems, the following solutions are proposed.

A second fixed sleeve is fixedly connected to the inner wall of the sliding arm. By providing the dual-axis motor, it serves as a power source for driving the sliding arm to move.

[0009] Preferably, the liquid guide pipe is fixedly connected to the left side of the second fixed sleeve at the end far from the support plate. A first rack is slidably connected to the inner wall of the second fixed sleeve. The outer surface of the first rack is slidably connected to the inner wall of the sliding arm. A gear is meshingly connected to the top of the first rack. A clamping plate is fixedly connected to the inner wall of the gear. The outer surface of the clamping plate is rotatably connected to the inner wall of the sliding arm. By providing the clamping plate, the position where the protruding part of the clamping surface of the clamping plate contacts the casing is made of rubber material, which can improve the friction between the clamping plate and the casing.

[0010] Preferably, the inner wall of the air storage shell is slidably connected to the outer surface of the first pressing plate. One end of the first air guide pipe far from the air storage shell is fixedly connected to the left side of the support plate. A second air guide pipe is fixedly connected to the right side of the support plate. A first sealing rod is fixedly connected to the outer surface of the sliding arm. The outer surface of the first sealing rod is slidably connected to the inner wall of the second air guide pipe. The second air guide pipe is fixedly connected to a fixed shell on the side far from the support plate. The fixed shell is fixedly connected to the side of the sliding arm close to the positioning plate on the side far from the positioning plate. Two sliding plates are slidably connected to the inner wall of the fixed shell. The outer surface of the sliding plates is slidably connected to the inner wall of the sliding arm. By providing the first sealing rod, it can determine whether a passage is formed between the first air guide pipe and the second air guide pipe.

[0011] Preferably, second sealing plates are fixedly connected to the sides of the two sliding plates close to each other. The outer surfaces of the second sealing plates are slidably connected to the inner wall of the sliding arm. Springs are fixedly connected to the sides of the two sliding plates close to each other. The ends of the springs far from the sliding plates are fixedly connected to the inner wall of the sliding arm. A connecting shell is fixedly connected to the side of the sliding arm far from the positioning plate.

By providing the air spraying holes, the air introduced into the air guide cavity can be sprayed out from the air spraying holes, thereby enhancing the cleaning effect on the debris adhering to the clamping surface of the clamping plate.

The fourth air guide pipe is fixedly connected to the inner wall of the sliding arm at the end far from the second pressing plate. This design enables the positioning plate to rotate and reset synchronously with the clamping plate when the positioning plate is reset, preventing the positioning plate from being reset first and thus hindering the clamping plate from driving the sliding arm to flip and reset.

[0013] A method for using a fixture for machining a motor housing includes the following steps:

[0014] S1: When using this device, first install this device at the designated position, and then start the double-shaft motor to drive the two fixed bent rods to approach each other to clamp the housing. At this time, it can be processed. Then start the hydraulic pump to flip the clamped housing through the clamping plate;

[0015] S2: When the two sliding arms approach each other, the first sealing rod no longer blocks between the first air guide pipe and the second air guide pipe. During the process of the first pressing plate moving to the left, a negative pressure will be formed inside the clamping plate by suction, and the housing can be adsorbed through the exhaust holes;

[0016] S3: After the device is reset, start the double-shaft motor to drive the sliding arm to reset, and take out the housing. At this time, restart the hydraulic pump to drive the positioning plate to move to the left, causing the clamping plate to flip, and at the same time spray air into the clamping plate through the air spray holes.

[0017] The present invention has the following beneficial effects:

[0018] In the present invention, the hydraulic pump is started to drive the positioning plate to move to the left. During the process of the positioning plate moving to the left, it will drive the first pressing plate to move together through the sliding rod. The first pressing plate will drive the first connecting rod to move. When the first connecting rod contacts the left inner wall of the first fixed sleeve, as the first connecting rod continues to move, it will drive the second pressing plate to move to the left together through the first fixed sleeve. This enables the positioning plate to move a certain distance to the left alone, giving space for the subsequent flipping of the housing. It should be noted that the inside of the support plate and the liquid guide pipe are both filled with hydraulic oil. When the first fixed sleeve drives the second pressing plate to move to the left, the second pressing plate will squeeze the hydraulic oil inside the support plate. The first sealing plate will seal the chute opened by the support plate for the protruding part of the second pressing plate. The squeezed hydraulic oil will be pushed into the liquid guide pipe, and the liquid guide pipe will lead the hydraulic oil into the second fixed sleeve. The hydraulic oil introduced into the second fixed sleeve will push the first rack to the right. The first rack moving to the right will drive the gear to rotate, and the gear can drive the clamping plate to rotate together, thereby flipping the clamped housing through the clamping plate. At this time, the other side of the housing can be processed. This design can automatically and accurately flip the housing without manual operation, thereby reducing the manual operation time and improving the overall processing efficiency.

[0019] When the two sliding arms of the present invention approach each other, they will drive the sealing rods to move together. When the sliding arms move to the final position, the through holes formed in the first sealing rod will coincide with the first air duct and the second air duct, thereby forming a passage between the first air duct and the second air duct. At the same time, the sliding arms will also drive the second sealing rod to move together, thereby blocking the air jet holes. During the process of the first pressing plate moving to the left, it will compress the air in the air storage shell. Since the air jet holes and the air guide cavity are blocked by the second sealing rod, the first pressing plate will push the air in the air storage shell into the first air duct. The first air duct will pass the air into the second air duct, and the second air duct will pass the air into the fixed shell. The air passing into the fixed shell will push the two sliding plates in the direction away from each other. During the movement of the sliding plates, they will drive the second sealing plate to move together, which can seal the space formed between the side of the sliding plate with the second sealing plate and the inner wall of the sliding arm. Therefore, during the movement of the sliding plates, they will inhale the air inside the clamping plate into the inside of the sliding arm through the third air duct and the connecting shell. Since the exhaust holes on the clamping surface of the clamping plate are blocked by the machine shell at this time, a negative pressure will be formed inside the clamping plate at this time, and the machine shell can be adsorbed through the exhaust holes. This design can adsorb the machine shell through the clamping plate during the flipping process of the machine shell, further enhancing the clamping effect of the clamping plate on the machine shell and preventing the machine shell from sliding and shifting during the flipping process, which affects the machining accuracy of the other side of the machine shell in the subsequent process.

[0020] During the process of the gear driving the clamping plate to flip, it will also drive the second rack to move to the left. The movement of the second rack to the left will drive the second connecting rod and the third pressing plate to move to the left together. During the process of the third pressing plate moving to the left, it will compress the air in the sliding arm and can push the air into the fourth air duct. The fourth air duct will pass the air into the second pressing plate, thereby compressing the air in the first fixed sleeve and increasing the air pressure in the first fixed sleeve. After the machining of the other side of the machine shell is completed, the hydraulic pump can be started to reset the whole device. Since the first fixed sleeve is filled with high-pressure air at this time, the first connecting rod will directly push the second pressing plate to move through the first fixed sleeve. Since the third pressing plate is also resetting at this time, the air pressure inside the first fixed sleeve is continuously decreasing, but the decreasing pressure is still sufficient to support the first connecting rod to push the first fixed sleeve until the clamping plate rotates to an angle where the positioning plate will not affect its reset. This design can make the clamping plate rotate and reset synchronously when the positioning plate is reset, preventing the positioning plate from resetting first and then hindering the clamping plate from driving the sliding arm to flip and reset.

[0021] After the device reset is completed, the present invention starts the dual-axis motor to drive the sliding arm to reset and removes the casing. At this time, the sealing rod one will be driven by the sliding arm to block the gap between the first air duct and the second air duct, and the sealing rod two will also be driven by the casing to form a passage between the air guide cavity and the air injection holes. At this time, the hydraulic pump is restarted to drive the positioning plate to move to the left, causing the clamping plate to flip, so that the long debris on the clamping plate during the processing of the casing will fall off automatically. At the same time, the pressure plate one will push the air in the air storage casing into the air guide cavity, and the air introduced into the air guide cavity will be ejected from the air injection holes, thereby enhancing the cleaning effect on the debris adhering to the clamping surface of the clamping plate. This design can clean the debris adhering to the surface of the clamping plate, preventing the debris from remaining on the clamping surface of the clamping plate and affecting the clamping accuracy of the casing.

On the right side of the first fixing sleeve 107, there is a second pressing plate 108 fixedly connected. On the left side of the second pressing plate 108, there is a first sealing plate 1081 fixedly connected. The outer surface of the second pressing plate 108 is slidably connected to the inner wall of the support plate 101. Start the hydraulic pump 102 to drive the positioning plate 103 to move to the left. During the process of the positioning plate 103 moving to the left, it will drive the first pressing plate 105 to move together through the sliding rod 104. The first pressing plate 105 will drive the first connecting rod 106 to move. When the left side of the inner wall of the first connecting rod 106 contacts the inner wall of the first fixing sleeve 107, as the first connecting rod 106 continues to move, it will drive the second pressing plate 108 to move to the left together through the first fixing sleeve 107. This can make the positioning plate 103 move a certain distance to the left alone, giving the subsequent housing 100 a space for flipping.

[0041] The inner wall of the second pressing plate 108 is slidably connected to the outer surface of the sliding rod 104. On the left side of the support plate 101, there is a liquid guide pipe 109 fixedly connected. On the outer surface of the liquid guide pipe 109, there is a sliding arm 110 fixedly connected.

The output end of the double-shaft motor 112 is threadedly connected to the inner wall of the fixed bent rod 111. Inside the sliding arm 110, there is a second fixing sleeve 113 fixedly connected. It should be noted that both the support plate 101 and the liquid guide pipe 109 are filled with hydraulic oil. When the first fixing sleeve 107 drives the second pressing plate 108 to move to the left, the second pressing plate 108 will squeeze the hydraulic oil inside the support plate 101.

The clamping plate 116 can be driven by the gear 115 to rotate together. Thus, the clamped machine shell 100 can be flipped by the clamping plate 116. At this time, the other side of the machine shell 100 can be processed. This design can automatically and accurately flip the machine shell 100 without manual operation, thereby reducing the manual operation time and improving the overall processing efficiency.

[0043] Embodiment 2. Please refer to Figure 6 - Figure 11 In this invention, it is a fixture for machining a motor housing. On the basis of Embodiment 1, the inner wall of the air storage shell 201 is slidably connected to the outer surface of the first pressing plate 105. One end of the first air guide tube 203 far from the air storage shell 201 is fixedly connected to the left side of the support plate 101. The second air guide tube 205 is fixedly connected to the right side of the support plate 101. A first sealing rod 204 is fixedly connected to the outer surface of the sliding arm 110. The outer surface of the first sealing rod 204 is slidably connected to the inner wall of the second air guide tube 205. A fixed shell 206 is fixedly connected to the side of the second air guide tube 205 far from the support plate 101. The fixed shell 206 is fixedly connected to the side of the sliding arm 110 close to the positioning plate 103 far from the positioning plate 103. Two sliding plates 207 are slidably connected to the inner wall of the fixed shell 206. The outer surface of the sliding plates 207 is slidably connected to the inner wall of the sliding arm 110. When the two sliding arms 110 approach each other, they will drive the first sealing rod 204 to move together. When the sliding arm 110 moves to the final position, the through hole formed in the first sealing rod 204 will coincide with the first air guide tube 203 and the second air guide tube 205, thereby forming a passage between the first air guide tube 203 and the second air guide tube 205.

[0044] On one side of the two sliding plates 207 close to each other, a second sealing plate 2071 is fixedly connected. The outer surface of the second sealing plate 2071 is slidably connected to the inner wall of the sliding arm 110. On one side of the two sliding plates 207 close to each other, a spring 208 is fixedly connected. The end of the spring 208 away from the sliding plate 207 is fixedly connected to the inner wall of the sliding arm 110. On the side of the sliding arm 110 away from the positioning plate 103, a connection shell 210 is fixedly connected. On the left and right sides of the connection shell 210, a third air duct 209 is fixedly connected. The end of the third air duct 209 away from the connection shell 210 is fixedly connected to the inner wall of the sliding arm 110. The outer surface of the clamping plate 116 is rotatably connected to the inner wall of the connection shell 210. Air guide cavities 211 are provided inside the positioning plate 103, the sliding rod 104 and the first pressing plate 105. An air jet hole 212 is provided on the right side of the positioning plate 103. A second sealing rod 213 is slidably connected to the inner wall of the positioning plate 103. The outer surface of the second sealing rod 213 is slidably connected to the inner wall of the sliding arm 110. The sliding arm 110 will also drive the second sealing rod 213 to move together, thereby blocking the air jet hole 212. During the process of the first pressing plate 105 moving to the left, it will compress the air in the air storage shell 201. Since the air jet hole 212 and the air guide cavity 211 are blocked by the second sealing rod 213, the first pressing plate 105 will push the air in the air storage shell 201 into the first air duct 203. The first air duct 203 will conduct the air into the second air duct 205. The second air duct 205 will conduct the air into the fixed shell 206. The air introduced into the fixed shell 206 will push the two sliding plates 207 in the direction away from each other. During the movement of the sliding plates 207, the second sealing plate 2071 will be driven to move together, which can seal the space formed between the side of the sliding plate 207 with the second sealing plate 2071 and the inner wall of the sliding arm 110. Therefore, during the movement of the sliding plates 207, the air inside the clamping plate 116 will be sucked into the inside of the sliding arm 110 through the third air duct 209 and the connection shell 210. Since the exhaust holes on the clamping surface of the clamping plate 116 are blocked by the machine shell 100 at this time, a negative pressure will be formed inside the clamping plate 116 at this time, and the machine shell 100 can be adsorbed through the exhaust holes. This design can adsorb the machine shell 100 through the clamping plate 116 during the flipping process of the machine shell 100, further enhancing the clamping effect of the clamping plate 116 on the machine shell 100 and preventing the machine shell 100 from sliding and shifting during the flipping process, which affects the processing accuracy of the other side of the machine shell 100. After the device is reset, the double-shaft motor 112 is started to drive the sliding arm 110 to reset, and the machine shell 100 is taken out. At this time, the first sealing rod 204 will be driven by the sliding arm 110 to block the connection between the first air duct 203 and the second air duct 205, and the second sealing rod 213 will also be driven by the machine shell 100 to form a passage between the air guide cavity 211 and the air jet hole 212. At this time, the hydraulic pump 102 is restarted to drive the positioning plate 103 to move to the left, so that the clamping plate 116 is flipped, and then the long debris that falls on the clamping plate 116 during the processing of the machine shell 100 will fall off automatically.Meanwhile, the pressing plate 105 will push the air in the air storage shell 201 into the air guide cavity 211, and the air introduced into the air guide cavity 211 will be ejected from the air injection holes 212, thereby enhancing the cleaning effect on the debris adhering to the clamping surface of the clamping plate 116. This design can clean the debris adhering to the surface of the clamping plate 116 to prevent the debris from remaining on the clamping surface of the clamping plate 116 and affecting the clamping accuracy of the machine shell.

[0045] The outer surface of the second rack 301 is slidably connected to the inner wall of the sliding arm 110, the outer surface of the second connecting rod 302 is slidably connected to the inner wall of the sliding arm 110, the outer surface of the pressing plate 303 is slidably connected to the inner wall of the sliding arm 110. Both the front and back of the pressing plate 108 are fixedly connected with a fourth air guide pipe 304. The fourth air guide pipe 304 is fixedly connected to the inner wall of the sliding arm 110 at the end far from the pressing plate 108. During the process of the gear 115 driving the clamping plate 116 to flip, it will also drive the second rack 301 to move to the left. The movement of the second rack 301 to the left will drive the second connecting rod 302 and the pressing plate 303 to move to the left together. During the process of the pressing plate 303 moving to the left, it will compress the air in the sliding arm 110 and can push the air into the fourth air guide pipe 304. The fourth air guide pipe 304 will introduce the air into the pressing plate 108, thereby compressing the air in the first fixing sleeve 107 and increasing the air pressure in the first fixing sleeve 107. After the machining of the other side of the machine shell 100 is completed, the hydraulic pump 102 can be started to reset the whole device. Since the first fixing sleeve 107 is filled with high-pressure air at this time, the connecting rod 106 will directly push the pressing plate 108 to move through the first fixing sleeve 107. Since the pressing plate 303 is also resetting at this time, the air pressure inside the first fixing sleeve 107 is continuously decreasing, but the decreasing pressure is still sufficient to support the connecting rod 106 to push the first fixing sleeve 107 until the clamping plate 116 rotates to an angle where the positioning plate 103 will not affect its reset. This design can make the clamping plate 116 rotate and reset synchronously when the positioning plate 103 is reset, preventing the positioning plate 103 from resetting first and then hindering the clamping plate 116 from driving the sliding arm 110 to flip and reset.

[0046] The usage method of the motor housing processing fixture includes the following steps:

[0047] S1: When using this device, first install this device at the designated position, and then start the double-shaft motor 112 to drive the two fixed bent rods 111 to approach each other to clamp the machine shell 100. At this time, it can be processed. Then start the hydraulic pump 102 to flip the clamped machine shell 100 through the clamping plate 116;

[0048] S2: When the two sliding arms 110 approach each other, the sealing rod 1 no longer blocks the gap between the first air duct 203 and the second air duct 205. During the process of the first pressing plate 105 moving to the left, the inside of the clamping plate 116 will be sucked out to form a negative pressure, and the housing 100 can be adsorbed through the exhaust holes.

[0049] S3: After the device is reset, start the dual-axis motor 112 to drive the sliding arm 110 to reset, and take out the housing 100. At this time, restart the hydraulic pump 102 to drive the positioning plate 103 to move to the left, so that the clamping plate 116 flips, and at the same time, air is sprayed onto the clamping plate 116 through the air spraying holes 212.

[0050] A specific application of this embodiment is:

[0051] When using this device, first install the device at the designated position, then move the casing 100 to be processed between the two sliding arms 110, and make the left side of the casing 100 contact the right side of the positioning plate 103. Then start the double-shaft motor 112 to drive the two fixed bent rods 111 to approach each other. The two fixed bent rods 111 will drive the two sliding arms 110 to move together, thereby driving the two clamping plates 116 to approach each other to clamp the casing 100. At this time, it can be processed. The position where the protruding part of the clamping surface of the clamping plate 116 contacts the casing 100 is made of rubber material, which can increase the friction between the clamping plate 116 and the casing 100. At this time, the casing 100 can be processed. After the processing is completed, the hydraulic pump 102 can be started to drive the positioning plate 103 to move to the left. During the process of the positioning plate 103 moving to the left, it will drive the pressing plate 105 to move together through the sliding rod 104. The pressing plate 105 will drive the connecting rod 106 to move. When the connecting rod 106 contacts the left inner wall of the fixed sleeve 107, as the connecting rod 106 continues to move, it will drive the pressing plate 108 to move to the left together through the fixed sleeve 107. This can make the positioning plate 103 move a certain distance to the left alone, giving the subsequent casing 100 the space to be flipped. It should be noted that both the support plate 101 and the liquid guide pipe 109 are filled with hydraulic oil. When the fixed sleeve 107 drives the pressing plate 108 to move to the left, the pressing plate 108 will squeeze the hydraulic oil inside the support plate 101. The sealing plate 1081 will seal the chute opened by the support plate 101 for the protruding part of the pressing plate 108. The squeezed hydraulic oil will be pushed into the liquid guide pipe 109. The liquid guide pipe 109 will introduce the hydraulic oil into the fixed sleeve 113. The hydraulic oil introduced into the fixed sleeve 113 will push the rack 114 to the right. The movement of the rack 114 to the right will drive the gear 115 to rotate. The gear 115 can drive the clamping plate 116 to rotate together, thereby flipping the clamped casing 100 through the clamping plate 116. At this time, the other side of the casing 100 can be processed. This design can automatically and accurately flip the casing 100 without manual operation, thereby reducing the manual operation time and improving the overall processing efficiency;

[0052] In the above process, when the two sliding arms 110 approach each other, they will drive the first sealing rod 204 to move together. After the sliding arm 110 moves to the final position, the through hole opened on the first sealing rod 204 will coincide with the first air guide pipe 203 and the second air guide pipe 205, thereby forming a passage between the first air guide pipe 203 and the second air guide pipe 205. At the same time, the sliding arm 110 will also drive the second sealing rod 213 to move together, thereby blocking the air jet hole 212. During the process of the first pressing plate 105 moving to the left, it will compress the air in the air storage shell 201. Since the air jet hole 212 and the air guide cavity 211 are blocked by the second sealing rod 213, the first pressing plate 105 will push the air in the air storage shell 201 into the first air guide pipe 203. The first air guide pipe 203 will pass the air into the second air guide pipe 205, and the second air guide pipe 205 will pass the air into the fixed shell 206. The air passing into the fixed shell 206 will push the two sliding plates 207 in the direction away from each other. During the movement of the sliding plate 207, it will drive the second sealing plate 2071 to move together, which can seal the space formed by the side of the sliding plate 207 with the second sealing plate 2071 and the inner wall of the sliding arm 110. Therefore, during the movement of the sliding plate 207, it will suck the air inside the clamping plate 116 into the inside of the sliding arm 110 through the third air guide pipe 209 and the connecting shell 210. Since the exhaust hole on the clamping surface of the clamping plate 116 is blocked by the machine shell 100 at this time, a negative pressure will be formed inside the clamping plate 116 at this time, and the machine shell 100 can be adsorbed through the exhaust hole. This design can adsorb the machine shell 100 through the clamping plate 116 during the flipping process of the machine shell 100, further enhancing the clamping effect of the clamping plate 116 on the machine shell 100 and preventing the machine shell 100 from sliding and shifting during the flipping process, which affects the processing accuracy of the other side of the machine shell 100 in the subsequent process;

[0053] During the process of the gear 115 driving the clamping plate 116 to flip, it will also drive the second rack 301 to move to the left. The movement of the second rack 301 to the left will drive the second connecting rod 302 and the third pressing plate 303 to move to the left together. During the process of the third pressing plate 303 moving to the left, it will compress the air in the sliding arm 110 and can push the air into the fourth air duct 304. The fourth air duct 304 will pass the air into the second pressing plate 108, and then can compress the air in the first fixing sleeve 107, making the air pressure in the first fixing sleeve 107 increase. After the machining of the other side of the machine case 100 is completed, the hydraulic pump 102 can be started to reset the whole device. Since the first fixing sleeve 107 is filled with high-pressure air at this time, the first connecting rod 106 will directly push the second pressing plate 108 to move through the first fixing sleeve 107. Since the third pressing plate 303 is also resetting at this time, the pressure of the air inside the first fixing sleeve 107 is continuously decreasing, but the decreasing pressure is also sufficient to support the first connecting rod 106 to push the first fixing sleeve 107 until the clamping plate 116 rotates to an angle where the positioning plate 103 will not affect its reset. This design can make the clamping plate 116 rotate and reset synchronously when the positioning plate 103 is reset, preventing the positioning plate 103 from being reset first and then hindering the clamping plate 116 from driving the sliding arm 110 to flip and reset;

[0054] After the device is reset, start the double-shaft motor 112 to drive the sliding arm 110 to reset and take out the machine case 100. At this time, the first sealing rod 204 will be driven by the sliding arm 110 to block the air duct between the first air duct 203 and the second air duct 205, and the second sealing rod 213 will also be driven by the machine case 100 to form a passage between the air guide cavity 211 and the air spraying holes 212. At this time, restart the hydraulic pump 102 to drive the positioning plate 103 to move to the left, making the clamping plate 116 flip, so that the long debris that fell on the clamping plate 116 during the machining of the machine case 100 will fall off automatically. At the same time, the first pressing plate 105 will push the air in the air storage case 201 into the air guide cavity 211, and the air passing into the air guide cavity 211 will be sprayed out from the air spraying holes 212, which can enhance the cleaning effect on the debris adhering to the clamping surface of the clamping plate 116. This design can clean the debris adhering to the surface of the clamping plate 116, preventing the debris from staying on the clamping surface of the clamping plate 116 and affecting the clamping accuracy of the machine case.
