Description

A mechanical coupler assembly machine Technical Field

[0001] This utility model belongs to the field of coupler technology, specifically relating to a mechanical coupler assembly machine. Background Technology

[0002] A mechanical coupler is a component used to connect two or more mechanical parts and transmit power, torque, or motion (such as couplings, hydraulic couplers, etc.). It is commonly found in mechanical transmission systems. A mechanical coupler assembly machine is a device specifically used to assemble a mechanical coupler with the output shaft of a motor. The traditional assembly method is to use a crane to lift the coupler for positioning, manually adjust the angle of the coupler to align it with the motor output terminal, and then use tools such as a hammer to strike the coupler to make it fully engage with the motor terminal.

[0003] In the existing technology, when mechanical couplers are assembled with motor output terminals, they are hoisted using cranes and cables. Since the bottom of the coupler is not supported, it will sway and shake during assembly, affecting the docking efficiency. Furthermore, the coupling agent is tapped to fit with the motor terminals. If this method is not operated properly or is used for a long time, it will damage the coupling agent and affect its service life. Summary of the Invention

[0004] The purpose of this utility model is to provide a mechanical coupler assembly machine. By moving the connecting plate, the support frame can be raised and lowered in linkage. This not only lifts the coupler to prevent it from swaying and sliding during docking and assembly, but also makes it easy to remove the entire assembly machine from the bottom of the coupler after the coupler assembly is completed. It can also push the coupler to move so that it can engage with the motor terminal, avoiding damage caused by hitting the coupler and extending its service life.

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] As shown in Figures 1-2 and 6-7, a mechanical coupler assembly machine includes a main screw 203 and a vertical plate 101 fixedly connected to one end of a base plate 1. A sliding plate 2 is slidably assembled on the top of the base plate 1. A lifting plate 201 is provided above the sliding plate 2. Support brackets 202 are symmetrically fixedly installed on the top of the lifting plate 201. A temporary positioning mechanism is provided on one side of the sliding plate 2 to limit the displacement of the sliding plate 2. The temporary positioning mechanism includes a rotating handle 211 rotatably mounted on the side wall of the sliding plate 2. A locking rod 212 is fixedly connected to one end of the rotating handle 211. The bottom of the sliding plate 2... A slot 213 is provided for the locking rod 212 to rotate and engage. A magnetic block 214 is fixedly connected to one side wall of the slot 213 for magnetically adsorbing the locking rod 212. A connecting plate 2 103 is provided on one side of the base plate 1. The base plate 1 is movably engaged with the connecting plate 2 103 through the connecting plate 1 102 and the positioning pin 104 at the end. A guide rail 105 is symmetrically fixedly connected to the top of the base plate 1. The sliding plate 2 is slidably connected to the guide rail 105. A locking groove 106 is provided between the two guide rails 105 for the locking rod 212 to rotate and engage. A positioning line 107 is provided on one side of the locking groove 106.

[0031] According to the above structure, the connecting plate 2 103 is fixedly connected to the fixing frame below the motor by bolts. The sliding plate 2 is placed at one end of the connecting plate 2 103, and the connecting plate 1 102 is pressed on the top of one end of the connecting plate 2 103. The positioning pin 104 is inserted into the preset holes and slots of the connecting plate 1 102 and the connecting plate 2 103 to temporarily lock them together. This allows the sliding plate 2 to remain parallel to the axis of the motor. The sliding plate 2 is moved to slide along the guide rail 105 until the end of the rotating handle 211 coincides with the positioning line 107. At this time, the rotating handle 211 is rotated to make the locking rod 212 rotate out from the inside of the slot 213 and embed into the locking groove 106, thus limiting the sliding plate 2 and preventing it from moving. The magnetic block 214 is used to attract the locking rod 212 when it rotates into the slot 213 to prevent it from falling due to gravity. Then, the coupler is hoisted to the top of the support frame 202 by a crane.

[0032] Referring to Figures 1-3, the vertical plate 101 is slidably connected from bottom to top with a first push rod 301, a second push rod 302, and a third push rod 303, which are used to drive the sliding plate 2, the elastic sliding mechanism, and the mechanical coupler to move, respectively. One end of the three push rods is fixedly connected to a connecting plate 3. The length of the second push rod 302 is greater than that of the first push rod 301. One end of the first push rod 301 is fixedly connected to an insertion rod 304. A spring ball 305 is elastically installed on the top of the insertion rod 304. The side wall of the sliding plate 2 has a slot 215 for the insertion rod 304 to be inserted and fitted. The inner wall of the slot 215 has a groove for the spring ball 305 to be elastically engaged. A servo electric cylinder 309 is fixedly assembled on the side wall of the vertical plate 101 to control the movement of the connecting plate 3. The output end of the servo electric cylinder 309 is fixedly connected to the connecting plate 3. An electric control switch 310 and a servo driver 311 are electrically installed on the side wall of the servo electric cylinder 309.

[0033] According to the above structure, the electronic control switch 310 is equipped with two buttons, one for controlling the extension of the servo cylinder 309 and the other for controlling its retraction. After pressing the retraction button, the electronic control switch 310 sends a command to the servo driver 311. The servo driver 311 interprets the signal and controls the servo cylinder 309 to retract. The servo cylinder 309 drives the connecting plate 3 to approach the vertical plate 101. The first push rod 301, the second push rod 302, and the third push rod 303 move together toward the sliding plate 2, so that the insertion rod 304 is inserted into the slot 215. After releasing the button, the connecting plate 3... When the movement stops, the spring ball 305 retracts during the insertion process. After the insertion rod 304 is fully inserted into the slot 215, the spring ball 305 pops out and matches the groove opened on the inner wall of the slot 215. Since the length of the second push rod 302 is greater than that of the first push rod 301, the second push rod 302 pushes the sliding cover 207 before the insertion rod 304 is inserted into the slot 215. The sliding plate 2 will not move during the pushing process of the first push rod 301 and the second push rod 302 due to the temporary locking of the locking rod 212 and the locking groove 106.

[0034] Referring to Figures 1 and 4-5, an elastic sliding mechanism is provided between the lifting plate 201 and the support frame 202 to control the rotation of the main screw 203. The elastic sliding mechanism includes a gear 205 fixedly connected to the top of the main screw 203, a guide clamp 206 fixedly connected to the top of the limiting rod 204, a sliding cover 207 slidably installed between the two guide clamps 206, and a number of teeth 208 equidistantly arranged on one side inner wall of the sliding cover 207 for meshing with the gear 205. An L-shaped plate 209 is fixedly connected to the top of the guide clamp 206, and a spring column 210 is fixedly connected between the two L-shaped plates 209. One end of the spring column 210 is fixedly connected to the sliding cover 207.

[0035] A limiting lifting mechanism is provided in the middle of the lifting plate 201 to drive the lifting plate 201 to move vertically. The limiting lifting mechanism includes a main screw 203 rotatably connected to the top of the sliding plate 2, and limiting rods 204 symmetrically fixed on both sides of the main screw 203. The lifting plate 201 is slidably sleeved with the limiting rods 204, and the lifting plate 201 is threadedly connected to the main screw 203. One end of the third push rod 303 is fixedly connected to the auxiliary screw 306. The outer wall of the auxiliary screw 306 is threadedly connected to the screw tube 307, and one end of the screw tube 307 is rotatably connected to the push plate 308.

[0036] According to the above structure, the sliding cover 207 begins to slide under the push of the second push rod 302, and at the same time the spring column 210 extends, the teeth 208 drive the gear 205 to rotate. Due to the restriction of the limit rod 204, the tangential force generated by the rotation of the gear 205 will be converted into the thrust of the lifting plate 201 moving axially. Its movement path is forcibly limited to axial movement. The lifting plate 201 begins to rise, driving the support bracket 202 to fit against the bottom of the coupler for alignment and lifting. The flange connection of the coupler is engaged in the gap between the two support brackets 202. Rotate the screw tube 307 to make it rotate and move along the auxiliary screw 306, so that the push plate 308 fits against one end of the coupler. Rotate the rotating handle 211 again to make the locking rod 212 rotate into the slot 213, and the sliding plate 2 unlocks and is limited.

[0037] Furthermore, pressing the retraction button of the electronic control switch 310 causes the connecting plate 3 to move the first push rod 301, the second push rod 302, and the third push rod 303 together. The first push rod 301 pushes the sliding plate 2 and the push plate 308 to push the coupler, so that the coupler is embedded in the motor output end. After assembly, pressing the extension button of the electronic control switch 310 causes the servo cylinder 309 to move the connecting plate 3, the first push rod 301, the second push rod 302, and the third push rod 303 away from the sliding plate 2 and the coupler. However, because the flange connection of the coupler is stuck between the two support brackets 202, although the insertion rod 304 is inserted into the slot 215, the support bracket 202 is blocked, and the sliding plate 2... Unable to move with the first push rod 301, instead, the first push rod 301 drives the insertion rod 304 to be pulled out of the slot 215, the spring ball 305 is squeezed and compressed into the insertion rod 304, and the second push rod 302 no longer squeezes the sliding cover 207. The sliding cover 207 rebounds and resets under the influence of the spring force of the spring column 210. The tooth 208 drives the gear 205 and the main screw 203 to rotate, causing the lifting plate 201 to descend. The lifting plate 201 drives the support frame 202 to descend, no longer supporting the coupler. After the support frame 202 descends, the coupler flange can no longer block it. At this time, after pulling out the positioning pin 104, the entire base plate 1 can be pulled out from the bottom of the coupler.

[0038] The working principle of this utility model is as follows: the connecting plate 2 103 is fixedly connected to the fixing frame below the motor by bolts. The sliding plate 2 is placed at one end of the connecting plate 2 103, and the connecting plate 1 102 is pressed on the top of one end of the connecting plate 2 103. The positioning pin 104 is inserted into the preset hole slot of the connecting plate 1 102 and the connecting plate 2 103 to temporarily engage the two, so that the sliding plate 2 and the axis of the motor can be kept parallel and consistent.

[0039] Furthermore, the sliding plate 2 is moved to slide along the guide rail 105 until the end of the rotating handle 211 coincides with the positioning line 107. At this time, the rotating handle 211 is rotated to make the locking rod 212 rotate out from the inside of the slot 213 and embed into the locking groove 106, thus limiting the sliding plate 2 so that it cannot move. The magnetic block 214 is used to attract the locking rod 212 when it rotates into the slot 213 to prevent it from falling due to gravity. Then, the coupler is hoisted to the top of the support frame 202 by the crane.

[0040] Furthermore, the electronic control switch 310 is equipped with two buttons, one for controlling the extension of the servo cylinder 309 and the other for controlling its retraction. When the retraction button is pressed, the electronic control switch 310 sends a command to the servo driver 311. The servo driver 311 interprets the signal and controls the servo cylinder 309 to retract. The servo cylinder 309 drives the connecting plate 3 to approach the vertical plate 101. The first push rod 301, the second push rod 302, and the third push rod 303 move together toward the sliding plate 2, so that the insertion rod 304 is inserted into the slot 215. After releasing the button, the connecting plate 3 stops moving.

[0041] Furthermore, during its insertion process, the spring ball 305 retracts first. After the insertion rod 304 is fully inserted into the slot 215, the spring ball 305 pops out and matches the groove opened on the inner wall of the slot 215. Since the length of the second push rod 302 is greater than that of the first push rod 301, the second push rod 302 pushes the sliding cover 207 before the insertion rod 304 is inserted into the slot 215. The sliding plate 2 will not move during the pushing process of the first push rod 301 and the second push rod 302 due to the temporary locking of the locking rod 212 and the locking groove 106.

[0042] Furthermore, the sliding cover 207 begins to slide under the push of the second push rod 302, and at the same time the spring column 210 extends, the teeth 208 drive the gear 205 to rotate. Due to the restriction of the limit rod 204, the tangential force generated by the rotation of the gear 205 will be converted into the thrust of the axial movement of the lifting plate 201. Its movement path is forcibly limited to axial movement, the lifting plate 201 begins to rise, and drives the support bracket 202 to fit against the bottom of the coupler for alignment and lifting. The flange connection of the coupler is engaged in the gap between the two support brackets 202. The screw tube 307 is rotated to rotate and move along the auxiliary screw 306, so that the push plate 308 fits against one end of the coupler.

[0043] Furthermore, by rotating the handle 211 again, the locking rod 212 is rotated into the slot 213, the sliding plate 2 is unlocked and limited, and the retraction button of the electric control switch 310 is pressed. The connecting plate 3 then drives the first push rod 301, the second push rod 302, and the third push rod 303 to move together. The first push rod 301 pushes the sliding plate 2 and the push plate 308 pushes the coupler, so that the coupler is embedded in the motor output end. After assembly, the extension button of the electric control switch 310 is pressed, and the servo cylinder 309 drives the connecting plate 3, the first push rod 301, the second push rod 302, and the third push rod 303 away from the sliding plate 2 and the coupler. However, because the flange connection of the coupler is stuck between the two support brackets 202, although the insertion rod 304 is inserted into the slot 215, the support bracket 202 is blocked, and the sliding plate 2 cannot move with the first push rod 301.

[0044] Furthermore, the first push rod 301 drives the insertion rod 304 to be pulled out of the slot 215, the spring ball 305 is squeezed and compressed into the insertion rod 304, and the second push rod 302 no longer squeezes the sliding cover 207. The sliding cover 207 rebounds and resets under the influence of the elastic force of the spring column 210. The tooth 208 drives the gear 205 and the main screw 203 to rotate, causing the lifting plate 201 to descend. The lifting plate 201 drives the support frame 202 to descend, no longer supporting the coupler. After the support frame 202 descends, the coupler flange can no longer block it. At this time, after pulling out the positioning pin 104, the entire base plate 1 can be pulled out from the bottom of the coupler.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
