Description

Technical Field

[0001] This application relates to the technical field of part assembly, and particularly to a magnetic drive type loading device. Background Art

[0002] When some plastic housing parts on an automobile are fixedly connected by bolts, it is necessary to install metal washers at the connection holes of the plastic housing parts. There is an interference fit between the metal washers and the connection holes. The metal washers can evenly disperse the pressure of nuts or bolts onto the parts, avoiding local stress concentration, thereby reducing the deformation or damage of the parts.

[0003] After the metal washers are installed, it is necessary to detect the disassembly force. The disassembly force refers to the force required to remove the metal washers from their installation positions during the disassembly process. If the disassembly force is less than a predetermined value, it will affect the subsequent connection effect. Existing loading devices can usually only perform the assembly of metal washers. After the metal washers are assembled, it is also necessary to apply a predetermined tensile force to the metal washers through a tensiometer, and then observe whether the metal washers will be pulled out of the installation holes. When the assembly quantity is large, if the disassembly force of each metal washer is detected, the workload will increase. Summary of the Invention

[0004] In order to facilitate the detection of the disassembly force of metal washers, this application provides a magnetic drive type loading device.

[0005] A magnetic drive type loading device provided by this application adopts the following technical solutions: A magnetic drive type loading device includes a base and a positioning mechanism arranged on the base for placing parts to be assembled; A driving mechanism includes a linear driving member, a mounting plate, and a magnetic plate. The mounting plate is arranged at the movable end of the linear driving member, and the magnetic plate is arranged on the mounting plate. The magnetic plate is used to attract metal washers; A force measuring mechanism includes a mounting block, a tension sensor, a pushing component, and a locking component. The mounting block is slidably connected to the mounting plate along the sliding direction of the movable end of the linear driving member. The magnetic plate is fixedly connected to the mounting block, and the tension sensor is connected between the mounting block and the mounting plate; The pushing component is arranged on the mounting block so that when the mounting block slides away from the part along with the mounting plate, the mounting block applies a tensile force to the metal washer pressed into the part; The locking component is arranged on the mounting plate so that when the metal washer is pressed into the part, the mounting block is fixedly connected to the mounting plate, and when a tensile force moving the metal washer away from the part is applied, the mounting block is slidably arranged.

[0006] By adopting the above technical solution, the metal washer is attracted and fixed on the magnetic plate. When the mounting plate moves downward, the metal washer can be moved downward, so that the metal washer is pressed into the mounting hole on the part, realizing the rapid assembly of the metal washer; after the assembly process of the metal washer is completed, the mounting plate moves upward. At this time, the pushing component applies an upward pulling force to the assembled metal washer. When the pulling force reaches a predetermined value, it can be judged whether the disassembly force meets the requirements by observing whether the metal washer is pulled out of the mounting hole. Therefore, this device can complete the assembly of the metal washer and the detection of the disassembly force successively, which helps to reduce the workload and thus improve the work efficiency; when the press-fitting process of the metal washer is carried out, the locking component fixes the mounting block on the mounting plate. Therefore, a large pressure can be applied to the metal washer at this time to complete the assembly of the metal washer. At the same time, the tension sensor can be protected to reduce the possibility of damage to the tension sensor caused by excessive extrusion; when the disassembly force is detected, the locking of the mounting block is cancelled, so that the pulling force applied to the metal washer can be detected by the tension sensor, thus realizing the detection of the disassembly force.

[0007] Optionally, the locking component includes a first toothed ring, a first gear, a rack, a plug rod and a first motor. The first toothed ring and the first gear are both rotatably connected to the mounting plate. There are multiple first gears. The first gears are meshed with the first toothed ring. The rack is slidably connected to the mounting plate. The number of racks is the same as the number of first gears. Each rack corresponds to a first gear and is meshed with the corresponding first gear. The plug rod is fixedly connected to the rack. A jack for the plug rod to insert is formed on the mounting block. The first motor is arranged on the mounting plate, and the output shaft of the first motor is connected to one of the first gears.

[0008] By adopting the above technical solution, after the first motor is started, it can drive the corresponding first gear to rotate, and the first toothed ring rotates accordingly, driving the other first gears to rotate. Therefore, multiple racks can slide synchronously, so that multiple plug rods slide inwards or outwards, thus completing the locking and fixing of the mounting block or canceling the locking of the mounting block.

[0009] Optionally, the pushing component includes an abutting block, a pushing block and a first spring. The abutting block is arranged on the side of the mounting block close to the magnetic plate. There are multiple abutting blocks arranged in a circumferential array. The pushing block is located on the side of the abutting block away from the magnetic plate. The pushing block is slidably connected to the abutting block. The first spring is connected between the pushing block and the abutting block. The abutting block is slidably connected to the mounting block. An adjusting component for driving the abutting block to slide is arranged on the mounting block.

[0010] By adopting the above technical solution, after the metal washer is attracted and fixed on the magnetic plate, the metal washer is located between the magnetic plate and the push block, and the top wall of the push block can abut against the bottom wall of the metal washer. Therefore, when the push block has an upward movement tendency, a pulling force can be applied to the metal washer on the loaded part, so as to detect the disassembly force. After the detection is completed, the adjusting assembly makes the abutting block slide inwards. The abutting block drives the push block to slide, so that the push block slides to the inside of the metal washer, which is convenient for subsequently extracting the push block from the metal washer. Then the abutting block slides outwards again and resets to the initial state. The outer wall of the abutting block can abut against the inner wall of the metal washer, so as to realize the positioning of the metal washer, which helps to ensure the assembly effect. In addition, the sliding setting of the abutting block can not only avoid the metal washer, so as to smoothly extract the push block, but also adjust the position of the abutting block as needed, so that the abutting block can position metal washers of different sizes, which helps to improve the applicability of the device.

[0011] Optionally, a bevel surface is provided on the outer side of the push block, so that when the metal washer slides towards the side close to the magnetic plate, the metal washer makes the push block slide inwards through the first bevel surface.

[0012] By adopting the above technical solution, pushing the metal washer upwards can simultaneously push the push block inwards, so that the process of loading the metal washer is more convenient, which helps to improve the work efficiency.

[0013] Optionally, an arc surface is provided on the outer side of the abutting block.

[0014] By adopting the above technical solution, it helps to enhance the abutting effect between the abutting block and the inner wall of the metal washer, so as to enhance the positioning effect of the metal washer.

[0015] Optionally, the adjusting assembly includes a second toothed ring, a second gear, a second motor, a connecting rope and a second spring. The second toothed ring and the second gear are both rotatably connected to the mounting block. The second toothed ring and the second gear are meshed. The output shaft of the second motor is connected to the second gear. The connecting rope is connected between the abutting block and the second toothed ring, so that when the second toothed ring rotates, it drives the abutting block to slide. The second spring is connected between the abutting block and the mounting block.

[0016] By adopting the above technical solution, starting the second motor can make the second gear and the second toothed ring rotate. When the second toothed ring rotates, it can drive the end of the connecting rope to rotate, and the connecting rope can pull the abutting block to slide outwards. When the output shaft of the second motor rotates in the reverse direction, the connecting rope becomes slack. At this time, the second spring can drive the abutting block to slide inwards, so that the position of the abutting block can be adjusted.

[0017] Optionally, a plurality of magnetic plates are provided, the number of the force measuring mechanisms is the same as the number of the magnetic plates, and each force measuring mechanism corresponds to a magnetic plate.

[0018] By adopting the above technical solution, multiple metal washers can be assembled simultaneously, which helps to improve work efficiency.

[0019] Optionally, an indicator light is provided on the mounting plate, and the indicator light is electrically connected to the tensile sensor.

[0020] By adopting the above technical solution, when the applied tensile force reaches a predetermined value, the color of the indicator light changes. At this time, the operator can be prompted to observe the situation of the metal washer, so as to judge whether the disassembly force meets the requirements by observing whether the metal washer slides out of the mounting hole on the part.

[0021] Optionally, a digital display is provided on the base, and the digital display is electrically connected to the tensile sensor.

[0022] By adopting the above technical solution, it is convenient to observe the tensile force value detected by the tensile sensor, so as to adjust the magnitude of the predetermined tensile force as needed.

[0023] Optionally, a blower is provided on the mounting plate, an exhaust hole is formed in the push block, one end of the exhaust hole penetrates the inclined surface, and the other end of the exhaust hole is communicated with the air outlet side of the blower.

[0024] By adopting the above technical solution, during the process of pressing the metal washer into the mounting hole on the part, since the push block is located below the metal washer, the push block can first blow and clean the inner wall of the mounting hole, blowing off dust and other impurities attached to the inner wall of the mounting hole, and then assembling the metal washer, which helps to improve the assembly effect of the metal washer; in addition, during the process of installing the metal washer outside the abutting block, the inner wall of the metal washer can also be blown and cleaned, so as to ensure the positioning effect between the metal washer and the abutting block.

[0025] In summary, the present application includes the following beneficial technical effects: 1. This device can not only achieve the rapid assembly of metal washers, but also detect the disassembly force after the metal washers are assembled, which helps to ensure the assembly effect, reduce the workload of detection, and thus improve work efficiency.

[0026] 2. The abutting block is slidably arranged, which can not only drive the push block to slide, so that the push block can be smoothly withdrawn from the assembled metal washer, but also adjust the initial position of the abutting block as needed, so that the abutting block can position metal washers of different sizes, which helps to improve the applicability of the device.

[0027] 3. The push block can blow air outward to clean the inner wall of the mounting hole on the part, thereby reducing dust and other debris attached to the inner wall of the mounting hole and ensuring the assembly effect. Description of the Drawings

Detailed implementation manners

[0030] The following is a further detailed description of the present application in conjunction with Figures 1-6 to the present application.

[0031] The embodiment of the present application discloses a magnetic drive type loading device. Refer to Figure 1 and Figure 2 , the magnetic drive type loading device includes a base 1 and a positioning mechanism 2, a driving mechanism 3 and a force measuring mechanism 4 arranged on the base 1. The positioning mechanism 2 includes a positioning block, and the positioning block is fixedly connected to the base 1, and the shape of the positioning block is adapted to the shape of the part 7 to be assembled. Placing the part 7 on the positioning block can position the part 7 and fix the position of the part 7. After the metal washer 6 is assembled, the part 7 can be slid upward and taken out.

[0032] Refer to Figure 3 and Figure 4, the driving mechanism 3 includes a linear driving member 31, a mounting plate 32, and a magnetic plate 33. The linear driving member 31 is a hydraulic cylinder. In other embodiments, the linear driving member 31 can also be a pneumatic cylinder. The cylinder body of the linear driving member 31 is fixedly connected to the base 1, and the end of the piston rod of the linear driving member 31 faces vertically downward. The mounting plate 32 is fixedly connected to the end of the piston rod of the linear driving member 31, and the mounting plate 32 is arranged horizontally. The magnetic plate 33 is arranged on the mounting plate 32. There are multiple magnetic plates 33, which are evenly spaced along the length direction of the mounting plate 32. The magnetic plate 33 is a magnet plate, and the metal washer 6 can be attracted and fixed on the magnetic plate 33. Therefore, after a metal washer 6 is adsorbed on each magnetic plate 33, the linear driving member 31 drives the mounting plate 32 to move downward, and the mounting plate 32 drives the magnetic plate 33 and the metal washer 6 to move downward, so as to press the metal washer 6 into the corresponding mounting hole on the part 7, thereby realizing the assembly of the metal washer 6.

[0033] There are multiple groups of force measuring mechanisms 4. The number of force measuring mechanisms 4 is the same as the number of magnetic plates 33, and each force measuring mechanism 4 corresponds to a magnetic plate 33. The force measuring mechanism 4 includes a mounting block 41, a tension sensor 42, a pushing component 43, and a locking component 44. A receiving groove 321 is formed on the mounting plate 32, and the top end of the mounting block 41 is slidably connected to the receiving groove 321 in the vertical direction. The magnetic plate 33 is fixedly connected to the bottom wall of the mounting block 41, and the bottom wall of the magnetic plate 33 is used to attract the metal washer 6. The tension sensor 42 is fixedly connected between the top wall of the mounting block 41 and the inner wall of the receiving groove 321. The pushing component 43 is arranged on the mounting block 41, and the pushing component 43 is used to apply a pulling force to the part 7. Therefore, after the metal washer 6 is assembled, when the mounting plate 32 slides upward, the pulling force applied to the metal washer 6 can be detected by the tension sensor 42. When the pulling force reaches a predetermined value and the metal washer 6 still does not slip off, it indicates that the disassembly force of the metal washer 6 reaches the predetermined requirement and the assembly effect is good.

[0034] The pushing component 43 includes a contact block 431, a pushing block 432, and a first spring 433. There are four contact blocks 431, which are arranged in a circular array. The top wall of the contact block 431 is attached to the bottom wall of the magnetic plate 33. The number of pushing blocks 432 is the same as the number of contact blocks 431, and each pushing block 432 corresponds to a contact block 431. The pushing block 432 is slidably connected to the bottom wall of the corresponding contact block 431. The sliding direction of the pushing block 432 is horizontal, and the sliding directions of multiple pushing blocks 432 are arranged in a circular array. The number of first springs 433 is the same as the number of contact blocks 431, and each first spring 433 corresponds to a contact block 431. The first spring 433 is fixedly connected between the contact block 431 and the pushing block 432. Under normal conditions, the first spring 433 is in its original length, and one end of the pushing block 432 is located outside the contact block 431.

[0035] Therefore, after the pushing block 432 slides inward in the horizontal direction, the metal washer 6 is slid upward to abut against the outer side of the abutting block 431, so that the outer wall of the abutting block 431 abuts against the inner wall of the metal washer 6. At this time, the first spring 433 is released, and the first spring 433 can cause the pushing block 432 to slide outward for reset. At this time, the metal washer 6 is located between the bottom wall of the magnetic plate 33 and the top wall of the pushing block 432. When the mounting plate 32 moves upward, the mounting block 41 can be caused to have an upward movement trend through the tension sensor 42. The mounting block 41 causes the abutting block 431 and the pushing block 432 to have an upward movement trend. Therefore, the pushing block 432 pressing against the bottom wall of the metal washer 6 can apply an upward pulling force to the metal washer 6, thereby detecting the disassembly force.

[0036] Further, a slope 4321 is provided on the outer side of the pushing block 432. Therefore, during the upward sliding of the metal washer 6, it will first abut against the slope 4321 on the pushing block 432, and then the metal washer 6 can push the pushing block 432 to slide inward when it slides upward, thus further simplifying the operation process.

[0037] Among them, the abutting block 431 is slidably connected to the mounting block 41. A slider 4311 is fixedly connected to the abutting block 431, and a chute 412 is opened at the bottom of the mounting block 41. The slider 4311 is slidably connected in the chute 412. An avoidance groove 331 adapted to the chute 412 is opened on the magnetic plate 33, and the slider 4311 slidably passes through the avoidance groove 331, so that the slider 4311 can slide smoothly. An adjusting assembly 5 for driving the abutting block 431 to slide is provided on the mounting block 41.

[0038] The adjusting assembly 5 includes a second toothed ring 51, a second gear 52, a second motor 53, a connecting rope 54 and a second spring 55. A mounting ring 413 is fixedly connected to the outer wall of the mounting block 41. The second toothed ring 51 and the second gear 52 are both rotatably connected to the mounting ring 413. The second toothed ring 51 and the mounting block 41 are coaxially arranged, and teeth are provided on the outer side of the second toothed ring 51. The second gear 52 meshes with the teeth of the second toothed ring 51. The second motor 53 is fixedly connected to the mounting ring 413, and the output shaft of the second motor 53 is coaxially and fixedly connected to the second gear 52. Therefore, after the second motor 53 is started, the second gear 52 can be rotated, and the second gear 52 drives the second toothed ring 51 to rotate.

[0039] There are four connecting ropes 54, corresponding to the four abutting blocks 431 respectively. The connecting ropes 54 are flexible rope bodies without elasticity. One end of the connecting rope 54 is fixedly connected to the slider 4311 on the corresponding abutting block 431, and the other end of the connecting rope 54 is fixedly connected to the inner wall of the second toothed ring 51. There are four second springs 55, corresponding to the four sliders 4311 respectively. The second springs 55 are fixedly connected between the sliders 4311 and the mounting block 41. The second springs 55 are in a stretched state, and the second springs 55 cause the abutting blocks 431 to have a tendency to slide inward. Under normal conditions, the connecting ropes 54 are in a tensioned and straightened state. Therefore, when the second toothed ring 51 rotates in one direction, the end of the connecting rope 54 can rotate along with it, and the connecting rope 54 pulls the abutting block 431 to slide outward through the slider 4311; when the second toothed ring 51 rotates in the other direction, the connecting rope 54 becomes slack, and at this time the second springs 55 can cause the abutting blocks 431 to slide inward.

[0040] When detecting the disassembly force, the metal washer 6 is located between the magnetic plate 33 and the push block 432. After the detection is completed, the abutting block 431 can be made to slide inward, and the abutting block 431 drives the push block 432 to slide inward, so that the push block 432 slides to the inner side of the metal washer 6, and then the push block 432 can slide upward from the inner hole of the metal washer 6. Then the push block 432 slides outward along with the abutting block 431 until the abutting block 431 slides to the initial state. At this time, the outer side of the abutting block 431 can abut against the inner wall of the metal washer 6, so the abutting block 431 can play a role in positioning the metal washer 6, thereby improving the assembly effect. The outer side of the abutting block 431 is provided with an arc surface, which helps to enhance the positioning effect on the metal washer 6.

[0041] Refer to Figure 4 、 Figure 5 and Figure 6, the locking assembly 44 includes a first toothed ring 441, a first gear 442, a rack 443, a plug rod 444 and a first motor 445. A receiving cavity 322 is provided on the mounting plate 32, and both the first toothed ring 441 and the first gear 442 are rotatably connected to the inner wall of the receiving cavity 322. There are multiple first gears 442 arranged in a circumferential array, and the first gears 442 mesh with the first toothed ring 441. The number of racks 443 is the same as the number of first gears 442, and each rack 443 corresponds to a first gear 442; the racks 443 are slidably connected in the receiving cavity 322, and the racks 443 mesh with the corresponding first gears 442. The plug rod 444 is fixedly connected to the end of the rack 443. One end of the plug rod 444 is slidably arranged in the receiving cavity 322, and the other end of the plug rod 444 can slide into the receiving groove 321. Correspondingly, a jack 411 for inserting the end of the plug rod 444 is provided on the side wall of the mounting block 41. Therefore, by inserting the plug rod 444 into the jack 411, the sliding of the mounting block 41 relative to the mounting plate 32 can be restricted, and the mounting block 41 can be fixedly connected to the mounting plate 32. The first motor 445 is fixedly connected to the mounting plate 32, and the output shaft of the first motor 445 is coaxially and fixedly connected to one of the first gears 442. Therefore, after the first motor 445 is started, the corresponding first gear 442 can be rotated, the first toothed ring 441 rotates accordingly, and then the other first gears 442 also rotate, so that the multiple first gears 442 rotate synchronously. Therefore, the multiple racks 443 and the plug rods 444 can slide synchronously, so as to fix the mounting block 41 or cancel the fixation of the mounting block 41.

[0042] In this embodiment, the output shafts of the first motor 445 and the second motor 53 can both be self-locked, that is, after the motors stop running, the output shafts cannot rotate under the action of external forces, which helps to ensure the stability of the structure.

[0043] A warning lamp is provided on the mounting plate 32, and the warning lamp is electrically connected to each tension sensor 42. Therefore, during the process of detecting the disassembly force, when the tension detected by the tension sensor 42 reaches a predetermined value, the warning lamp can change color. At this time, maintain this tension, and then observe whether the metal washer 6 becomes loose, and the test result can be quickly judged. When the disassembly force of one or more metal washers 6 is unqualified, the corresponding metal washers 6 can be removed, and then these metal washers 6 can be reassembled. After the assembly is completed, these metal washers 6 can be retested.

[0044] A digital display is also provided on the base 1, and the digital display is electrically connected to each tension sensor 42. Therefore, the digital display can display the tension detected by each tension sensor 42 in real time, which is convenient for observation.

[0045] Refer to Figure 4, a blower is also provided on the mounting plate 32. An exhaust hole 4322 is formed in the pushing block 432. One end of the exhaust hole 4322 penetrates through the inclined surface 4321 of the pushing block 432, and the other end of the exhaust hole 4322 is fixedly connected to an exhaust duct. The exhaust duct is a flexible duct, and the end of the exhaust duct away from the exhaust hole 4322 is communicated with the air outlet side of the blower. Therefore, the blower can blow air out through the exhaust duct and the exhaust hole 4322. During the process of the metal washer 6 sliding down for assembly, the impurities or dust adhering to the inner wall of the mounting hole of the part 7 can be blown off, thereby ensuring the assembly effect of the metal washer 6.

[0046] The implementation principle of the magnetic drive type loading device in the embodiment of the present application is as follows: Place the part 7 on the positioning block, and an installation hole for assembling the metal washer 6 is provided at the top of the part 7. Then move the metal washer 6 to the lower part of the corresponding pushing block 432, and slide the metal washer 6 upward. When the metal washer 6 moves upward, it can push the pushing block 432 to slide horizontally inward until the top wall of the metal washer 6 fits against the bottom wall of the magnetic plate 33, thereby sucking and fixing the metal washer 6 on the magnetic plate 33. Then, each metal washer 6 is loaded onto the corresponding magnetic plate 33 with the same operation.

[0047] In the initial state, the end of the insertion rod 444 is inserted into the insertion hole 411, so the mounting block 41 can be fixedly connected to the mounting plate 32. Then the linear driving member 31 drives the mounting plate 32 to move downward. The mounting plate 32 drives the mounting block 41 to move downward, and the mounting block 41 drives the metal washer 6 to move downward until the metal washer 6 is press-fitted into the corresponding mounting hole on the part 7 to achieve interference fit. After the press-fitting is completed, the first motor 445 is started. Under the cooperation of the first gear 442 and the first toothed ring 441, the multiple racks 443 slide outward synchronously, so that the insertion rod 444 slides out of the corresponding insertion hole 411, canceling the locking connection between the mounting block 41 and the mounting plate 32. Then the linear driving member 31 makes the mounting plate 32 move upward. The mounting plate 32 can make the mounting block 41 and the abutting block 431 tend to move upward through the tension sensor 42. Since the metal washer 6 is located between the magnetic plate 33 and the pushing block 432, the pushing block 432 can apply an upward pulling force to the metal washer 6 mounted on the part 7, and then the corresponding pulling force is detected through the tension sensor 42. When the pulling force reaches a predetermined value, the indicator light changes color. At this time, the operator observes whether the metal washer 6 slides out of the mounting hole; if the metal washer 6 slides out, it indicates that the disassembly force does not meet the requirements. If the metal washer 6 does not slide out, it indicates that the disassembly force meets the requirements.

[0048] Next, the second motor 53 is started. With the cooperation of the second gear 52 and the second toothed ring 51, the connecting rope 54 can be loosened. At this time, the second spring 55 causes the abutting block 431 to slide inwards, and the abutting block 431 drives the pushing block 432 to slide inwards until the pushing block 432 slides to the inside of the metal washer 6; then the mounting plate 32 moves upwards, driving the abutting block 431 and the pushing block 432 upwards, so that the pushing block 432 is withdrawn from the metal washer 6. After the reset of the mounting plate 32 is completed, the output shaft of the second motor 53 rotates in the reverse direction again, so that the connecting rope 54 pulls the abutting block 431 to slide outwards until the abutting block 431 is reset to the initial state.

[0049] The first motor 445 is started again, so that the plurality of racks 443 and the insertion rods 444 slide inwards synchronously, and the ends of the insertion rods 444 slide into the corresponding insertion holes 411, thereby fixing the mounting block 41 to the mounting plate 32 again, facilitating the next assembly.

[0050] The above are the optional embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
