Description

Technical Field

[0001] This invention relates to the field of stator frame press-fitting technology, specifically a multi-station stator frame press-fitting production line. Background Technology

[0002] In the field of motor technology, the stator frame is used to cooperate with the stator core and play an insulating role in the stator core. Therefore, the stator frame needs to be pressed into the stator. The stator frame pressing device is a key piece of equipment in motor manufacturing. It is used to accurately press the insulating frame into the stator core to ensure the electrical performance and structural reliability of the motor.

[0003] Currently, most common stator frame pressing devices use mechanical rigid clamping combined with linear impact pressing, which leads to concentrated clamping force. This makes the frame (especially thin-walled plastic frames) prone to local deformation, surface scratches, cracks, or even breakage during pressing and transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station stator frame press-fitting production line to solve the problem that clamping may damage the frame in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-station stator frame pressing production line includes two sets of pressing components arranged side by side. One set of pressing components presses the frame onto one side of the stator, and the other set of pressing components presses the frame onto the other side of the stator. Each pressing component includes a moving unit and a pushing unit.

[0007] The moving unit includes a horizontal drive group and a vertical drive group, which are connected. The vertical drive group is provided with a connecting plate, the connecting plate is provided with a push cylinder, the push cylinder is provided with a fixing plate, and the fixing plate is provided with a limit hole.

[0008] The pushing unit includes a fixing ring, a docking body, and a pressing body. The fixing ring is disposed on a connecting plate. The docking body includes a plurality of clamping plates. The clamping plates and the pressing body are connected to the fixing ring. The pressing body is disposed on the outside of the clamping plates.

[0009] The horizontal drive group and the vertical drive group drive the push unit to move, the docking body docks the skeleton with the stator, and the pressing body presses the skeleton and the stator together.

[0010] When the stator moves to the bottom of the pressing assembly, the fixing clamp then clamps and fixes the stator. The moving unit drives the pushing unit to move towards the side closer to the vibrating feed plate, so that the docking body clamps the skeleton on the mechanical arm. Then the transverse drive group drives the longitudinal drive group and the pushing unit to move, so that the longitudinal drive group and the pushing unit move to the top of the stator. Then the longitudinal drive group drives the pushing cylinder and the pushing unit to move, so that the pushing cylinder and the pushing unit move towards the side closer to the stator.

[0011] When the push cylinder moves, it drives the fixed plate and the limiting hole to move, causing the limiting hole to move closer to the stator, so that the stator passes through the limiting hole, and the limiting hole further supports the stator.

[0012] After the stator is fixed, the mating body drives the skeleton into the stator. Then the mating body loosens the skeleton, causing the skeleton to separate from the mating body. Then the pressing body moves towards the side closer to the stator, causing the pressing body to push the skeleton into the stator, thus completing the pressing process.

[0013] Preferably, a plurality of clamping plates are arranged around the axis of the fixing ring. Each clamping plate consists of a fixing rod and a plurality of expansion plates. The fixing rod is connected to the fixing ring, and the expansion plates are disposed at the bottom of the fixing rod. A first airbag is disposed between the plurality of expansion plates.

[0014] When the docking body clamps the skeleton, the longitudinal drive group first moves the docking body to the side closer to the skeleton, so that several fixing rods extend into the skeleton. Then, by activating the pressure control unit in the first pipe, the gas in the gas storage chamber is quickly delivered to several first airbags. The gas quickly fills the airbags, causing them to expand under the pressure. The first airbags then push several expansion plates to move in all directions, so that the expansion plates come into contact with the skeleton, thereby achieving the clamping treatment of the skeleton. Then, the moving unit drives the docking body to move directly above the stator.

[0015] When press fitting is required, the longitudinal drive group moves the docking body toward the stator, causing the docking body to drive the frame into the stator. Then, the pump suction device is started, and at the same time, the pressure control unit in the first pipe is turned on, so that the gas in the first airbag is transported to the air storage chamber through the first pipe for storage. At this time, due to the gas discharge, the first airbag loses the gas support, and the first airbag contracts. Then, the first airbag drives the expansion plate to contract, causing the expansion plate to separate from the frame.

[0016] Preferably, the pressing body comprises a second airbag and a pressing ring. The second airbag is disposed between the pressing ring and the fixed ring. One side of the second airbag is connected to the fixed ring, and the other side of the second airbag is connected to the pressing ring. The side wall of the second airbag is slidably connected to the fixed ring. The pressing ring is slidably connected to the fixed ring. The side wall of the fixed ring is provided with a plurality of guide rods. The side wall of the pressing ring is provided with a plurality of limiting rings. The limiting rings are slidably connected to the guide rods.

[0017] When the skeleton is clamped and placed in the docking body, the second airbag is in a contracted state, and the pressing ring is contracted in the sliding channel; when pressing is required, the pump suction device collects the gas in the first airbag into the air storage chamber, causing the expansion plate to separate from the skeleton.

[0018] Then, the pressure control unit in the second pipeline is activated, and the gas in the gas storage chamber is rapidly delivered to the second airbag. The second airbag expands rapidly due to the rapid delivery of gas, and then expands along the sliding channel, causing the second airbag to impact the pressing ring. Under the action of expansion, the pressing ring moves towards the side closer to the stator. During the movement, the pressing ring encounters the frame and pushes the frame towards the stator, thus achieving the pressing process between the frame and the stator. When the pressing ring moves, it drives the limiting ring to move, so that the limiting ring moves along the axis of the guide rod. Thus, the pressing ring can only move along the axis of the fixed ring.

[0019] After the skeleton is pressed together, the pumping device draws the gas from the second airbag into the air storage chamber. The second airbag then contracts. During the contraction of the second airbag, the pressing ring is reset, causing the pressing ring to contract into the sliding channel.

[0020] Preferably, a gas storage chamber is provided inside the fixing ring, a first pipe is provided inside the fixing rod, and the two ends of the first pipe are respectively connected to the gas storage chamber and the first air bag. A second pipe is provided between the second air bag and the gas storage chamber, and the two ends of the second pipe are respectively connected to the gas storage chamber and the second air bag. A pump suction device is connected to the outside of the gas storage chamber, and a pressure control unit is provided inside both the first pipe and the second pipe.

[0021] Preferably, the outer side of the expansion plate is provided with friction texture.

[0022] By setting friction textures on the sidewalls of the expansion plate, the expansion plate can better clamp the skeleton without causing wear on the surface of the skeleton during the clamping process.

[0023] Preferably, the outer wall of the fixing ring extends downward and forms a sliding channel with the mating body, and the pressing ring slides along the sliding channel.

[0024] Preferably, it also includes a skeleton insertion device, which is equipped with a material conveying track, and a number of fixing clamps are arranged along the material conveying track. Two sets of pressing components are also arranged above the material conveying track, and a flipping mechanism is arranged between the two pressing components.

[0025] The feeding track drives the stator to move, so that the stator passes through one pressing component, a flipping mechanism, and another pressing component in sequence. Then, one side of the stator is first pressed into a circular skeleton. After the circular skeleton is pressed, the feeding track moves the stator closer to the flipping mechanism, so that the flipping mechanism clamps and flips the stator, and then the other side of the stator flips to the top. Then the feeding track continues to transport the stator to another pressing component, so that the other pressing component presses the octagonal skeleton into the stator, thus completing the pressing process of the stator skeleton. During the pressing and flipping stages, the stator is positioned and fixed by a fixing clamp, so that the stator will not shift during pressing.

[0026] Preferably, the skeleton insertion device has two sets of vibrating feeding plates on one side, the output end of the vibrating feeding plates is located on the skeleton insertion device, and a mechanical arm is provided on the side of the skeleton insertion device near the output end of the vibrating feeding plates. The mechanical arm is used to transfer the skeleton.

[0027] One set of vibrating feeding trays holds a circular skeleton, and the other set holds an octagonal skeleton. Both the circular and octagonal skeletons are conveyed to the side closer to the skeleton insertion device via the vibrating feeding trays. When the circular and octagonal skeletons move to the output end of the vibrating feeding trays, the controller controls the mechanical arm to start. The mechanical arm transfers the circular and octagonal skeletons to the side closer to the pressing assembly, so that the pressing assembly can clamp the circular and octagonal skeletons.

[0028] Preferably, a mechanical arm is provided on the other side of the insertion frame device, and a stator conveying mechanism is provided on the side of the mechanical arm away from the insertion frame device. The mechanical arm transfers the stator on the stator conveying mechanism to the conveying track.

[0029] Workers place a pallet filled with stators on the stator conveying mechanism and remove the stator pallet from the top of the conveying mechanism. Then, the mechanical arm clamps the stator on the stator conveying mechanism and transports it to the side near the conveying track, and finally places it on the conveying track. The conveying track drives the stator to move, so that the stator is subjected to skeleton pressing along the conveying track.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] Through two sets of press-fitting components arranged in parallel and cooperating with a flipping mechanism, continuous and automated press-fitting of the skeletons on both sides of the stator is achieved, significantly improving production efficiency; an airbag-driven docking body and press-fitting body structure is adopted, and the first airbag is used to achieve flexible clamping and release of the skeleton, and the second airbag drives the press-fitting ring to complete smooth impact press-fitting, which not only avoids damage to the surface of the skeleton caused by traditional mechanical clamping, but also ensures the uniformity and precision of the press-fitting process. The fixed ring is internally provided with an air storage cavity and a pipeline system, and the clamping and press-fitting actions are联动 controlled through the same air source, with a compact structure and rapid response; at the same time, this production line integrates vibrating feeding, robotic arm transfer, a feeding track, and a fixed clamp positioning system, achieving full-process automation from stator feeding, skeleton supply, double-sided press-fitting to finished product output.

[0049] In one specific embodiment of the present invention, a plurality of clamping plates are arranged around the axis of the fixing ring 15.

The second airbag 171 is disposed between the pressing ring 172 and the fixing ring 15. One side of the second airbag 171 is connected to the fixing ring 15, and the other side of the second airbag 171 is connected to the pressing ring 172.

[0051] In one specific embodiment of the present invention, a gas storage chamber 152 is provided inside the fixing ring 15, a first pipe is provided inside the fixing rod 161, and the two ends of the first pipe are respectively connected to the gas storage chamber 152 and the first airbag 163. A second pipe is provided between the second airbag 171 and the gas storage chamber 152, and the two ends of the second pipe are respectively connected to the gas storage chamber 152 and the second airbag 171. A pump suction device (a gas pump) is connected to the outside of the gas storage chamber 152. A pressure control unit (a pressure control valve) is provided inside both the first pipe and the second pipe.

[0052] In one specific embodiment of the present invention, the outer side of the expansion plate 162 is provided with friction texture.

[0053] In one specific embodiment of the present invention, the outer wall of the fixing ring 15 extends downward and forms a sliding channel with the docking body 16, and the pressing ring 172 slides along the sliding channel.

[0054] Working principle of the invention:

[0055] The staff places a pallet filled with stators on the stator conveying mechanism 5 and removes the stator pallet from the stator conveying mechanism 5. Then the mechanical arm 4 clamps the stator on the stator conveying mechanism 5 and conveys it to the side close to the conveying track 21, and finally places it on the conveying track 21. The conveying track 21 drives the stator to move, so that the stator is subjected to skeleton pressing along the conveying track 21.

[0056] One set of vibrating feeding trays 3 contains a circular skeleton, and the other set of vibrating feeding trays 3 contains an octagonal skeleton. Both the circular and octagonal skeletons are conveyed to the side near the skeleton insertion device 2 via the vibrating feeding trays 3. When the circular and octagonal skeletons move to the output end of the vibrating feeding trays 3, the controller controls the mechanical arm to start. The mechanical arm transfers the circular and octagonal skeletons to the side near the pressing assembly 1, so that the pressing assembly 1 can clamp the circular and octagonal skeletons.

[0057] The feeding track 21 drives the stator to move, so that the stator passes through one pressing component 1, the flipping mechanism 23 and the other pressing component 1 in sequence. Then, one side of the stator is first pressed into a circular frame. After the circular frame is pressed, the feeding track 21 moves the stator closer to the flipping mechanism 23, so that the flipping mechanism 23 clamps and flips the stator, and then the other side of the stator is flipped to the top. Then the feeding track 21 continues to feed the stator to the other pressing component 1, so that the other pressing component 1 presses the octagonal frame into the stator, thereby completing the pressing process of the stator frame. During the pressing and flipping stages, the stator is positioned and fixed by the fixing clamp 22, so that the stator will not shift during pressing. Finally, after pressing is completed, the stator is output from the output end of the feeding track 21.

[0058] When the stator moves to the bottom of the pressing assembly 1, the fixing clamp 22 clamps and fixes the stator. The moving unit 11 drives the pushing unit 12 to move towards the side closer to the vibrating feeding plate 3, so that the docking body 16 clamps the skeleton on the mechanical arm. Then the transverse drive group 13 drives the longitudinal drive group 14 and the pushing unit 12 to move, so that the longitudinal drive group 14 and the pushing unit 12 move to the top of the stator. Then the longitudinal drive group 14 drives the pushing cylinder 132 and the pushing unit 12 to move, so that the pushing cylinder 132 and the pushing unit 12 move towards the side closer to the stator.

[0059] When the push cylinder 132 moves, it drives the fixed plate 141 and the limiting hole 142 to move, so that the limiting hole 142 moves closer to the stator, so that the stator passes through the limiting hole 142, and then the limiting hole 142 further supports the stator.

[0060] When the docking body 16 clamps the skeleton, the longitudinal drive group 14 first moves the docking body 16 closer to the skeleton, so that several fixing rods 161 extend into the skeleton. Then, by activating the pressure control unit in the first pipe, the gas in the gas storage chamber 152 is quickly delivered to several first airbags 163. The gas quickly fills the airbags, causing them to expand under the pressure. The first airbags 163 then push several expansion plates 162 to move in all directions, so that the expansion plates 162 come into contact with the skeleton, thereby clamping the skeleton. Then, the moving unit 11 moves the docking body 16 directly above the stator. When the docking body 16 clamps and places the skeleton, the second airbag 171 is in a contracted state, and the pressing ring 172 contracts within the sliding channel.

[0061] When press fitting is required, the longitudinal drive group 14 moves the docking body 16 toward the stator, so that the docking body 16 drives the frame to extend into the stator. Then the pump suction device is started, and at the same time the pressure control unit in the first pipeline is turned on, so that the gas in the first airbag 163 is transported to the gas storage chamber 152 through the first pipeline for storage. At this time, due to the gas discharge, the first airbag 163 loses the gas support, and the first airbag 163 contracts. Then the first airbag 163 drives the expansion plate 162 to contract, so that the expansion plate 162 separates from the frame.

[0062] Subsequently, the pressure control unit in the second pipeline is activated, and the gas in the gas storage chamber 152 is rapidly delivered to the second airbag 171. The second airbag 171 expands rapidly due to the rapid delivery of gas, and then expands along the sliding channel, causing the second airbag 171 to impact the pressing ring 172. Under the action of expansion, the pressing ring 172 moves towards the side closer to the stator. During the movement, the pressing ring 172 encounters the frame and pushes the frame towards the stator, thereby achieving the pressing process between the frame and the stator. When the pressing ring 172 moves, it drives the limiting ring 173 to move, so that the limiting ring 173 moves along the axis of the guide rod 151. Thus, the pressing ring 172 can only move along the axis of the fixed ring 15.

[0063] After the skeleton is pressed together, the pumping device draws the gas from the second airbag 171 into the air storage chamber 152, and then the second airbag 171 contracts. During the contraction of the second airbag 171, the pressing ring 172 is reset, so that the pressing ring 172 contracts into the sliding channel.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
