Description

Technical Field

[0001] The invention relates to the technical field of automobile processing equipment, in particular to an automobile parts assembly auxiliary device. Background Art

[0002] During the automobile manufacturing process, workers are required to install parts inside the vehicle body. Since the interior of the vehicle is narrow and it is not convenient for large machinery to enter, workers are currently mostly installing manually. In order to improve assembly efficiency, major manufacturers use some auxiliary assembly equipment during the assembly process to increase production capacity requirements. According to a Chinese patent with the authorization announcement number CN113199234B, an automobile parts assembly auxiliary device is disclosed, which can realize the auxiliary delivery of workers in the assembly line operation during the automobile manufacturing process. There is no need for workers to frequently walk around to take parts and install screws, which saves time and effort, and can accurately control the number of installation screws to be taken, so as to avoid workers missing or taking them by mistake, thereby improving work efficiency;

[0003] The automobile parts assembly auxiliary device supplies bolts by means of belt conveyor. Since the assembly speeds of different workers are different, it is difficult for the automobile parts assembly auxiliary device to ensure that the conveying speed is synchronized with the assembly speed of the workers. If the assembly speed of the assembly workers is lower than the feeding speed of the conveyor belt, the bolts will accumulate at the assembly station. In addition, the device is insufficient for the differential feeding of bolts of different models and cannot meet the free switching of bolts of different models during assembly. For this reason, we propose an automobile parts assembly auxiliary device to solve the above technical problems. Summary of the invention

[0045] As a preferred solution of the present invention, it also includes:

[0046] The acrylic guard plate is fixedly arranged on the lower part of a side of the pre-storage bucket away from the cross bracket, and the acrylic guard plate is used for protecting the feeding part and the adjusting part.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. In the present invention, the driving gear is driven to rotate by the output shaft of the locking motor, and the central vertical shaft is further driven to rotate together with the cross bracket through the transmission action of the driven gear. The rotation of the cross bracket drives the four feeding parts to rotate together, and the feeding part storing the bolts of corresponding models and specifications is rotated to face the assembly station through the setting of the switching part, so that bolts of different specifications can be conveniently selected, and the practicability is strong.

[0049] 2. In the present invention, by pulling the bolt located between the two clamping flaps downward, the nut of the bolt applies a downward extrusion force to the two clamping flaps, causing the two clamping flaps to rotate downward along the outer wall of the clamping flaps by a certain angle, and then the bolt can be directly pulled out, which is easy to operate and greatly improves the assembly efficiency.

[0050] 3. In the present invention, in the process of the clamping flap being rotated downward and then rotated upward to reset, the trigger block will be driven to rotate twice, so that the trigger rod of the trigger switch extends outward and is squeezed and retracted by the trigger block again. When the trigger rod of the trigger switch retracts, the reset signal of the clamping flap is transmitted to the controller, and the controller immediately starts the servo motor to drive the active pulley to rotate. The rotation of the active pulley further drives the feeding horizontal axis together with the groove wheel to rotate a certain angle through the conduction effect of the power belt and the driven pulley, and the bolts in the groove of the groove wheel are transported to the top of the two clamping flaps. Under the action of gravity, the bolts naturally fall off from the groove of the groove wheel to the top of the two clamping flaps. Since the gap between the clamping flaps is smaller than the diameter of the bolt nut, the bolt is stuck between the two clamping flaps and remains in a vertical state, waiting for the worker to take it next time, so as to achieve on-demand supply to prevent the bolts from accumulating in the assembly station.

[0051] 4. In the present invention, a thread thrust effect is generated by rotating the adjusting screw and the adjusting seat, so that an adjusting seat threadably connected to the adjusting screw is moved along the axial direction of the guide rod. At the same time, the movement of the adjusting seat will drive the reversing gear to rotate through the push bar and the rack connected thereto. The rotation of the reversing gear further drives the other rack and the push bar to move in the opposite direction, thereby driving the other adjusting seat to move, thereby adjusting the distance between the two adjusting seats. Adjusting the distance between the two adjusting seats is to adjust the spacing between the two clamping flaps, thereby being suitable for auxiliary feeding of bolts of different coarse and fine specifications, thereby improving the scope of application of the device.

DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] See also Figures 1 to 8The technical solution provided by the present invention specifically includes the following embodiments:

[0063] An automobile parts assembly auxiliary device includes a profile cabinet 100; a switching portion 200, which is arranged on the top of the profile cabinet 100 and extends to the inside of the profile cabinet 100; a feeding portion 300, which is arranged on the periphery of the switching portion 200, and the number of the feeding portions 300 is four; an adjusting portion 400, which is arranged on both sides of the bottom of the feeding portion 300; a controller 500, which is arranged on the left side of the profile cabinet 100; and a trigger switch 600, which is arranged inside the feeding portion 300.

[0064] For further details, please refer to Figure 1 to Figure 3 As shown:

[0065] The switching part 200 includes a central vertical axis 201, which is rotatably set at the top center position of the profile cabinet 100; a cross bracket 202, which is fixedly set on the upper part of the outer wall of the central vertical axis 201, and the feeding part 300 is fixedly installed on the end of the cross bracket 202 by fixing bolts; a driven gear 203, which is fixedly set on the lower part of the outer wall of the central vertical axis 201; a stepping locking motor 204, which is fixedly set on the inner side of the upper surface of the profile cabinet 100, and the output shaft of the stepping locking motor 204 extends to the top periphery of the profile cabinet 100, and the stepping locking motor 204 is electrically connected to the controller 500; a driving gear 205, which is fixedly set on the output of the stepping locking motor 204, and the driving gear 205 and the driven gear 203 are meshed with each other, and the gear ratio of the driving gear 205 to the driven gear 203 is 1:9.

[0066] Specifically, by inputting commands to the controller 500, the controller 500 controls the step locking motor 204 to start, so that its output shaft drives the driving gear 205 to rotate, and further drives the central vertical axis 201 together with the cross bracket 202 to rotate through the transmission action of the driven gear 203. The rotation of the cross bracket 202 drives the four feeding parts 300 to rotate together. After the feeding part 300 storing the bolts of corresponding models and specifications is rotated to an angle facing the assembly station, the step locking motor 204 stops running and locks its output shaft, so that the adjusted feeding part 300 will not rotate again, ensuring stability. Through the setting of the switching part 200, it is convenient to select bolts of different specifications, and it is more practical.

[0067] Further, see Figure 2 to Figure 8 As shown:

[0068] The feeding part 300 includes a pre-storage bucket 301, which is fixedly arranged at the end of the cross bracket 202 and is used to store bolts; a feeding frame 302, which is fixedly arranged at the bottom of the pre-storage bucket 301, and the interior of the feeding frame 302 is connected with the interior of the pre-storage bucket 301; a feeding horizontal axis 303, which is arranged inside the feeding frame 302 to rotate along the radial direction of the central vertical axis 201; a groove wheel 304, which is located inside the feeding frame 302 and is fixedly arranged on the outer wall of the feeding horizontal axis 303, and a gap of 1.5 to 2.0 mm is provided between the outer wall of the groove wheel 304 and the inner wall of the feeding frame 302;

[0069] The feeding section 300 also includes a driven pulley 305, which is fixedly arranged at the rear of the outer wall of the feeding horizontal axis 303 and is used to drive the feeding horizontal axis 303 to rotate; a servo motor 306, which is fixedly arranged on the outer surface of the pre-storage bucket 301, and the servo motor 306 is electrically connected to the controller 500; a driving pulley 307, which is fixedly arranged on the output shaft of the servo motor 306; a power belt 308, which is fixedly arranged on the periphery of the driven pulley 305 and the driving pulley 307, and is used to transmit the power of the driving pulley 307 to the driven pulley 305; an adjustment seat 309, which is arranged on the periphery of the pre-storage bucket 301, and the number is two, and the two adjustment seats 309 are symmetrically distributed about the axis of the feeding horizontal axis 303, and the trigger switch 60 0 is fixedly installed inside one of the adjustment seats 309 along the radial direction of the feeding horizontal axis 303; the shaft pin 3010 is fixedly installed on both sides of the adjustment seat 309; the clamping flap 3011 is rotatably arranged on the outer walls of the two adjustment seats 309 located on both sides of the shaft pin 3010; the torsion spring 3012 is fixedly arranged on the periphery of the shaft pin 3010, and the torsion spring 3012 is fixedly installed between the adjustment seat 309 and the shaft pin 3010, and is used for rotational reset of the clamping flap 3011; the torsion spring 3012 is fixedly arranged on the middle part of the inner side surface of a clamping flap 3011 close to the trigger switch 600, and the side surface of the trigger block 3013 away from the feeding horizontal axis 303 abuts against the end of the trigger rod of the trigger switch 600.

[0070] Specifically, as attached Figure 4As shown, the worker pulls the bolt located between the two clamping flaps 3011 downward, and the nut of the bolt applies a downward squeezing force to the two clamping flaps 3011, causing the two clamping flaps 3011 to rotate downward by a certain angle along the outer wall of the clamping flap 3011. The downward rotation of the clamping flap 3011 causes the torsion spring 3012 to elastically deform, thereby generating a rebound force. When the nut portion of the bolt slides downward from between the two clamping flaps 3011, the rebound force of the torsion spring 3012 causes the clamping flap 3011 to rotate upward and reset along the outer wall of the axle pin 3010. During the process of the clamping flap 3011 rotating upward and then resetting, it will drive the trigger block 3013 to rotate twice together, so that the trigger rod of the trigger switch 600 extends outward and is squeezed and retracted by the trigger block 3013 again. After the firing rod retracts, the reset signal of the clamping flap 3011 is transmitted to the controller 500, and the controller 500 immediately starts the servo motor 306, so that its output shaft drives the active pulley 307 to rotate. The rotation of the active pulley 307 further drives the feeding horizontal axis 303 and the groove wheel 304 to rotate a certain angle through the conduction effect of the power belt 308 and the driven pulley 305, so as to transport the bolts in the groove of the groove wheel 304 to the top of the two clamping flaps 3011. Under the action of gravity, the bolts naturally fall off from the groove of the groove wheel 304 to the top of the two clamping flaps 3011. Since the gap between the clamping flaps 3011 is smaller than the diameter of the bolt nut, the bolt is stuck between the two clamping flaps 3011 and remains in a vertical state, waiting for the worker to take it next time, so as to achieve on-demand supply to prevent the bolts from accumulating in the assembly station.

[0071] Further, see Figures 4 to 8 As shown:

[0072] The adjusting portion 400 includes an adjusting screw 401, which is rotatably mounted on one side of the feeding frame 302 along the radial direction of the feeding horizontal axis 303, and the adjusting screw 401 passes through one of the adjusting seats 309 and is connected to the through hole of the adjusting seat 309 by threaded cooperation; a guide rod 402, which is fixedly arranged on the outer side of the feeding frame 302 along the radial direction of the feeding horizontal axis 303, and there are four guide rods 402 on the outer side of the same feeding frame 302, and the four guide rods 402 are equally divided on both sides of the central axis of the feeding frame 302, and are located on the two sides of the feeding frame 302. An adjustment seat 309 is slidably connected to the guide rods 402 distributed on both sides of the feeding frame 302; a push bar 403 is fixedly set at one end of the adjustment seat 309, and the push bar 403 is bent at a right angle; a rack 404 is fixedly set on the top of the push bar 403; a positioning shaft 405 is fixedly installed on the outer surface of the feeding frame 302 along the axial direction of the feeding horizontal axis 303; a reversing gear 406 is rotatably set on the outer wall of the feeding horizontal axis 303, and the reversing gear 406 is meshed with the upper and lower racks 404 to synchronize the movement of the upper and lower racks 404.

[0073] Specifically, by rotating the adjusting screw 401 and the adjusting seat 309 to generate a threaded thrust effect, an adjusting seat 309 threadedly connected to the adjusting screw 401 will move along the axial direction of the guide rod 402. At the same time, the movement of the adjusting seat 309 will drive the reversing gear 406 to rotate through the push bar 403 and the rack 404 connected thereto. The rotation of the reversing gear 406 further drives the other rack 404 and the push bar 403 to move in the opposite direction, thereby driving the other adjusting seat 309 to move, thereby adjusting the distance between the two adjusting seats 309. Adjusting the distance between the two adjusting seats 309 is to adjust the spacing between the two clamping flaps 3011, so that it is suitable for auxiliary feeding of bolts of different coarse and fine specifications, thereby improving the scope of application of the device.

[0074] Further, see Figure 1-2 As shown:

[0075] The cabinet also includes a cabinet door 101, which is rotatably arranged on the front side of the profile cabinet 100, and the cabinet door 101 and the profile cabinet 100 are installed via hinges.

[0076] The cabinet door 101 is provided to facilitate opening of the profile cabinet 100 . On the one hand, it is convenient for later maintenance of the stepping locking motor 204 . On the other hand, the interior of the profile cabinet 100 can be sealed to improve the storage effect of the profile cabinet 100 .

[0077] The cabinet 100 further includes a louver opening 102 , which is opened at the lower portion of the outer surface of the cabinet 100 , and a plurality of louver openings 102 are provided.

[0078] By providing the louver opening 102 , a heat dissipation effect can be provided for the stepping locking motor 204 , thereby preventing the stepping locking motor 204 from being damaged due to poor heat dissipation.

[0079] It also includes an acrylic guard plate 700, which is fixedly arranged on the lower part of a side of the pre-storage bucket 301 away from the cross bracket 202, and the acrylic guard plate 700 is used to protect the feeding part 300 and the adjusting part 400.

[0080] When the automobile parts assembly auxiliary device of the present solution is working, bolts of different types are placed independently through four pre-storage buckets 301, and the universal wheels at the bottom of the profile cabinet 100 are arranged to facilitate the movement of the device to the assembly station, and the direction of the controller 500 is directed toward the assembly station, so that the controller 500 is convenient to operate;

[0081] When bolts are needed, the worker inputs the command to the controller 500, and the controller 500 controls the stepping locking motor 204 to start, so that its output shaft drives the driving gear 205 to rotate, and further drives the central vertical shaft 201 together with the cross bracket 202 to rotate through the transmission action of the driven gear 203. The rotation of the cross bracket 202 drives the four feeding parts 300 to rotate together. After the feeding part 300 storing the bolts of the corresponding model and specification is rotated to an angle facing the assembly station, the stepping locking motor 204 stops running and locks its output shaft, so that the adjusted feeding part 300 will not rotate again to ensure stability;

[0082] As attached Figure 4 As shown, the worker pulls the bolt located between the two clamping flaps 3011 downward, and the nut of the bolt applies a downward squeezing force to the two clamping flaps 3011, causing the two clamping flaps 3011 to rotate downward by a certain angle along the outer wall of the clamping flap 3011. The downward rotation of the clamping flap 3011 causes the torsion spring 3012 to elastically deform, thereby generating a rebound force. When the nut portion of the bolt slides downward from between the two clamping flaps 3011, the rebound force of the torsion spring 3012 causes the clamping flap 3011 to rotate upward and reset along the outer wall of the axle pin 3010. During the process of the clamping flap 3011 rotating upward and then resetting, it will drive the trigger block 3013 to rotate twice together, so that the trigger rod of the trigger switch 600 extends outward and is squeezed and retracted by the trigger block 3013 again. After the firing rod is retracted, the reset signal of the clamping flap 3011 is transmitted to the controller 500, and the controller 500 immediately starts the servo motor 306, so that its output shaft drives the active pulley 307 to rotate. The active pulley 307 rotates through the conduction effect of the power belt 308 and the driven pulley 305, further driving the feeding horizontal axis 303 and the groove wheel 304 to rotate a certain angle, and the bolts in the groove of the groove wheel 304 are transported to the top of the two clamping flaps 3011. Under the action of gravity, the bolts naturally fall off from the groove of the groove wheel 304 to the top of the two clamping flaps 3011. Since the gap between the clamping flaps 3011 is smaller than the diameter of the bolt nut, the bolts are stuck between the two clamping flaps 3011 and remain in a vertical state, waiting for the next worker to take them, so as to achieve on-demand supply to prevent the bolts from accumulating in the assembly station.

[0083] The present device generates a thread thrust effect between the rotating adjusting screw 401 and the adjusting seat 309, thereby moving an adjusting seat 309 threadably connected to the adjusting screw 401 along the axial direction of the guide rod 402. At the same time, the movement of the adjusting seat 309 will drive the reversing gear 406 to rotate through the push bar 403 and the rack 404 connected thereto. The rotation of the reversing gear 406 further drives the other rack 404 and the push bar 403 to move in the opposite direction, thereby driving the other adjusting seat 309 to move, thereby adjusting the distance between the two adjusting seats 309. Adjusting the distance between the two adjusting seats 309 is to adjust the spacing between the two clamping flaps 3011, thereby being suitable for auxiliary feeding of bolts of different coarse and fine specifications, thereby improving the scope of application of the present device.

[0084] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
