Description

Technical Field

[0001] This invention relates to the field of nut tightening machine technology, and specifically to an automatic nut tightening machine for a charging gun. Background Technology

[0002] The charging gun is a key device for charging electric vehicles. One end is connected to a power socket, and the other end is inserted into the charging interface of the electric vehicle. Its main function is to provide power to the electric vehicle and ensure its normal operation. The charging gun consists of a charging head and a cable, which are connected and fixed together by a nut.

[0003] With the popularization of new energy vehicles, the demand for electric vehicle charging piles is also increasing. However, when fixing the charging gun head and the cable connection end, tightening the nut is a key step. Existing technology often uses the traditional manual tightening method. This method is not only time-consuming and laborious, but also has problems such as inconsistent tightening torque and human error, which affect the charging effect and safety. The existing locking device cannot achieve adaptive locking of nuts of different sizes, which means that different locking parts need to be replaced when tightening nuts for different charging guns.

[0004] Therefore, the present invention provides an automatic locking machine for charging gun nuts to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an automatic locking machine for charging gun nuts, which solves the problem of adapting to nuts of different sizes and achieving automatic snap-fit ​​and locking.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An automatic locking machine for charging gun nuts includes a base, a drive cylinder, and a rotating disk. A fixed frame is fixedly mounted on the top of the base. A control box is fixedly mounted on the outer wall of the fixed frame. A locking component is fixedly mounted on the inner top wall of the fixed frame. The locking component is fixedly connected to the output end of the drive cylinder, which is fixedly mounted on the top of the fixed frame. The rotating disk is rotatably connected to the fixed frame and drivenly connected to the locking component. Multiple fixed boxes are fixedly mounted on the top of the rotating disk, and the multiple fixed boxes are evenly distributed along the circumference of the rotating disk. The control box is electrically connected to the drive cylinder. This device, through the locking component and rotating disc, can automatically lock the charging gun nut. The locking component can automatically clamp the nut and is suitable for various nut sizes, increasing the device's flexibility. When tightening nuts of different sizes, there is no need to replace the locking component. Simultaneously, the device's fixing box can fix charging guns of different sizes, and during the locking process, it ensures the stability of the charging gun, preventing locking failure or unstable locking due to shaking during nut tightening.

[0008] Preferably, the inner wall of the fixing box is provided with a clamping groove, and a clamping arc block is slidably connected to the upper part of the clamping groove. A clamping spring is fixedly installed at one end of the clamping arc block, and the other end of the clamping spring is fixedly connected to the inner side wall of the fixing box. A clamping plate is slidably connected to the lower part of the clamping groove, and a push-off post is fixedly installed at the end of the clamping plate away from the clamping groove. A pressing rod is slidably connected to the inside of the fixing box, with one end of the pressing rod located outside the top of the fixing box, and the other end of the pressing rod... A clamping inclined block is fixedly installed, the width of which decreases from top to bottom. The inclined end of the clamping inclined block abuts against one end of the abutment post. A return spring is fixedly installed at the bottom of the clamping inclined block, and the bottom of the return spring is fixedly connected to the inner bottom wall of the fixed box. When using this device initially, the charging gun is first inserted into the clamping slot. The two clamping arc blocks are installed opposite each other. Initially, the two clamping arc blocks are brought closer together under the action of the clamping spring. When the charging gun is inserted into the clamping slot... At this point, the two clamping arc blocks, under the action of the clamping springs, clamp and fix the charging gun, achieving initial fixation. When the locking component is pressed down, it will abut the pressing rod, causing the pressing rod to move the clamping inclined block downwards. The clamping inclined block drives the abutting post and clamping plate to move, and the clamping plate fixes the charging gun again, preventing displacement or shaking during locking. Simultaneously, when the pressing rod loses its pressing force, the return spring allows the pressing rod to move upwards, and the clamping plate... The device automatically clamps the charging gun, detaching it from the charging gun. Through the clamping arc blocks, it achieves a double-fixation effect, preventing clamping failure. Simultaneously, the two clamping plates move synchronously and at the same distance, enabling automatic positioning and clamping of the charging gun. Furthermore, the automatic positioning and clamping are linked with the locking mechanism, automatically reinforcing before locking and automatically opening after locking for easy charging gun replacement.

[0009] Preferably, the locking component includes a locking box and a mounting box. The mounting box is fixedly mounted on the top of the locking box, and the top of the mounting box is fixedly connected to the output end of the drive cylinder. A drive gear plate is fixedly mounted on one end of the bottom of the locking box. A locking cylinder is rotatably connected inside the locking box. A bearing ring is mounted on the outer wall of the locking cylinder and installed on the inner side wall of the locking box. External teeth are provided on the outer wall of the locking cylinder. A drive shaft is rotatably connected to the inner wall of the locking box. A drive gear is fixedly mounted on the outer wall of the drive shaft and meshes with the external teeth. The top of the drive shaft is fixedly connected to the output end of the drive motor, which is fixedly mounted on the side wall of the mounting box. When locking, the device first moves downward by activating the drive cylinder. The drive cylinder will then move the mounting box and locking box downward, causing the locking cylinder to automatically engage with the nut of the charging gun. Simultaneously, the drive motor is activated, and under the action of the drive shaft, the drive gear rotates the locking cylinder, thus automatically locking the nut. When the locking box descends, the bottom of the locking box will abut against the top of the pressing rod, thus securing the charging gun.

[0010] Preferably, a guide groove is provided on the inner wall of the locking cylinder, and a compensating rod is slidably connected inside the guide groove. The compensating rod is slidably connected inside the locking rod, and the locking rod is slidably connected inside the locking cylinder. A compensating spring is fixedly installed at one end of the compensating rod, and the other end of the compensating spring is fixedly connected to the inner wall of the locking rod. The outer side of one end of the compensating rod matches the nut.

[0011] Preferably, a compression spring is fixedly installed on the outer wall of the compensating rod, the compression spring is located inside the guide groove, and the other end of the compression spring is fixedly connected to the inner wall of the guide groove. There are two locking rods, arranged opposite to each other. A locking wedge is slidably connected inside the locking cylinder, the thickness of the locking wedge increasing from top to bottom. The inclined end of the locking wedge abuts against the outer wall of one end of the locking rod. A locking spring is fixedly installed on the top of the locking wedge, and the other end of the locking spring is fixedly connected to the inner top wall of the locking cylinder. A push-off post is fixedly installed on the bottom of the locking wedge, and the other end of the push-off post passes through the inner wall of the locking cylinder. The bottom wall is located on the outside. When the locking box of this device descends, the abutment column will abut against the top of the fixed box. Under the action of force, the abutment column will move upward. At this time, under the action of the locking wedge, it will abut against the two locking rods and move relative to each other. The two locking rods clamp the nut. Under the action of the rotation of the locking cylinder, the locking rods rotate and lock the nut. This device, through the setting of the compensation rod, can make the locking rod slide smoothly inside the locking cylinder. At the same time, the guide groove plays a guiding role. The locking rod can lock different nuts. After locking, it is easy to disassemble. The locking of this device can also be linked with the descent of the locking box.

[0012] Preferably, a rotating shaft is fixedly installed at the bottom of the rotating disk, and rotating bevel gears are fixedly installed on the outer wall of the rotating shaft; a linkage shaft is rotatably connected to the inner wall of the base, and a linkage bevel gear is fixedly installed on the outer wall of one end of the linkage shaft, the linkage bevel gear meshing with the rotating bevel gears; a linkage gear is unidirectionally driven connected to the outer wall of the other end of the linkage shaft, and the linkage gear meshing with the drive gear plate.

[0013] Preferably, the linkage shaft has a through hole inside, and a one-way inclined block is slidably connected inside the through hole. One end of the one-way inclined block is triangular in shape, and a compression spring is fixedly installed at one end of the one-way inclined block inside the through hole. The other end of the compression spring is fixedly connected to the inner wall of the through hole. The inner wall of the linkage gear has a one-way inclined groove, which matches the one-way inclined block. When the locking box of this device descends and drives the drive gear plate to move, the drive gear plate will not drive the linkage shaft to rotate. At this time, the inclined surface of the one-way inclined block is opposite to the inclined surface of the one-way inclined groove, and the rotation of the linkage gear will not cause the linkage shaft to rotate. The moving linkage shaft rotates. To prevent the rotating disk from rotating during locking, the rotating disk is kept in a stable state during locking to prevent deviations. When the locking box moves upward to reset, the one-way wedge block extends under the action of the compression spring. At this time, the straight surface of the one-way wedge block is opposite to the straight surface of the one-way wedge groove. When the linkage gear is driven to rotate by the drive gear plate, the linkage gear will drive the linkage shaft to rotate. This enables the linkage shaft to drive the rotating disk to change the charging gun that is about to be locked. This allows the device to automatically change the locked charging gun, and the change is linked with the action of the locking box.

[0014] Preferably, the upper part of the drive gear plate is a smooth plate, and meshing teeth are fixedly installed on the outer wall of the drive gear plate. A compensation gear plate is slidably connected inside the drive gear plate, and compensation teeth are provided on the outer wall of the compensation gear plate. The compensation teeth are offset from the meshing teeth, and there are two compensation teeth. When it is necessary to control the number of teeth on the outer wall of the drive gear plate, the device can adjust the displacement of the compensation gear plate to achieve automatic adjustment of the number of teeth. When the drive gear plate drives the linkage gear to rotate for a long time, in order to avoid the phenomenon of rotation difference, the device can compensate through the compensation gear plate to ensure that the two can maintain the same rotation. The reset of the drive gear plate can drive the rotating disk to replace it. At the same time, the upper part of the drive gear plate is set as a smooth plate, which can prevent the rotating disk from starting to rotate when the drive gear plate starts to reset, and prevent the rotating disk from rotating before the locking cylinder leaves the fixed box.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This device, through the setting of locking components and rotating disc, can automatically lock the charging gun nut. The locking components can automatically clamp the nut and are suitable for various nut sizes, increasing the flexibility of the device. When tightening nuts of different sizes, there is no need to replace the locking components. At the same time, the fixing box of this device can fix charging guns of different sizes. During the locking process, it can ensure the stability of the charging gun and avoid locking failure or unstable locking caused by shaking when locking the nut.

[0017] 2. This device, through the setting of the clamping arc block, can automatically clamp the charging gun. Under the action of the clamping plate, it can achieve a double fixing effect to avoid clamping failure. At the same time, the two clamping plates of this device can achieve synchronous and same distance automatic displacement, realizing the function of automatic positioning and automatic clamping of the charging gun. Moreover, the automatic positioning and clamping of this device can form a linkage effect with the locking component, automatically reinforcing before locking and automatically opening after locking, which is convenient for replacing the charging gun.

[0018] 3. This device, through the setting of the compensation rod, allows the locking rod to slide smoothly inside the locking cylinder. At the same time, the guide groove plays a guiding role. The locking rod can lock different nuts. After locking, it is easy to disassemble. In addition, the locking of this device can be linked with the descent of the locking box.

[0019] 4. The rotation of the linkage gear in this device will not drive the linkage shaft to rotate. In order to avoid the rotation of the rotating disk during locking, the rotating disk can be kept in a stable state during locking to prevent the phenomenon of locking deviation. At the same time, the rotating disk can replace the charging gun that is about to be locked, so that this device can automatically replace the charging gun to be locked, and the replacement and locking box action are linked.

[0020] 5. When it is necessary to control the number of teeth on the outer wall of the drive gear plate, this device can adjust the displacement of the compensation gear plate to achieve automatic adjustment of the number of teeth. When the drive gear plate drives the linkage gear to rotate for a long time, in order to avoid the phenomenon of rotation difference, this device can also compensate through the compensation gear plate to ensure that the two can maintain the same rotation. The reset of the drive gear plate can drive the rotating disk to replace. At the same time, the upper part of the drive gear plate of this device is set as a smooth plate, which can prevent the rotating disk from starting to rotate when the drive gear plate starts to reset, and prevent the rotating disk from rotating before the locking cylinder leaves the fixed box.

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] An automatic locking machine for charging gun nuts, as shown in the attached figure. Figure 1-2As shown, the device includes a base 1, a drive cylinder 5, and a rotating disk 6. A mounting bracket 2 is fixedly installed on the top of the base 1. A control box 3 is fixedly installed on the outer wall of the mounting bracket 2. A locking component 4 is fixedly installed on the inner top wall of the mounting bracket 2. The locking component 4 is fixedly connected to the output end of the drive cylinder 5. The drive cylinder 5 is fixedly installed on the top of the mounting bracket 2. The rotating disk 6 is rotatably connected to the mounting bracket 2. The rotating disk 6 is drivenly connected to the locking component 4. A fixed box 7 is fixedly installed on the top of the rotating disk 6. There are multiple fixed boxes 7, which are evenly arranged along the circumference of the rotating disk 6. The control box 3 and... The drive cylinder 5 is electrically connected; this device, through the setting of locking component 4 and rotating disk 6, can automatically lock the charging gun nut. Locking component 4 can automatically clamp the nut and is suitable for various sizes of nuts, increasing the flexibility of the device. When tightening nuts of different sizes, there is no need to replace locking component 4. At the same time, the fixing box 7 of this device can fix charging guns of different sizes. During the locking process, it can ensure the stability of the charging gun and avoid locking failure or unstable locking caused by shaking when locking the nut.

[0040] As attached Figure 3-4As shown, the inner wall of the fixing box 7 has a clamping groove 701. A clamping arc block 702 is slidably connected to the upper part of the clamping groove 701. A clamping spring 703 is fixedly installed at one end of the clamping arc block 702, and the other end of the clamping spring 703 is fixedly connected to the inner side wall of the fixing box 7. A clamping plate 704 is slidably connected to the lower part of the clamping groove 701. A push post 705 is fixedly installed at the end of the clamping plate 704 away from the clamping groove 701. A pressing rod 706 is slidably connected to the inside of the fixing box 7. One end of the pressing rod 706 is located outside the top of the fixing box 7, and the other end of the pressing rod 706 is fixedly installed... The device is equipped with clamping inclined blocks 707, the width of which decreases from top to bottom. The inclined end of the clamping inclined block 707 abuts against one end of the abutment post 705. A return spring 708 is fixedly installed at the bottom of the clamping inclined block 707, and the bottom of the return spring 708 is fixedly connected to the inner bottom wall of the fixed box 7. During initial use, the charging gun is first inserted into the clamping groove 701. The two clamping arc blocks 702 are installed opposite each other. Initially, the two clamping arc blocks 702 are brought closer together under the action of the clamping spring 703. When the charging gun is inserted into the clamping groove 701, this… When the two clamping arc blocks 702 are pressed down by the clamping spring 703, they clamp and fix the charging gun, achieving initial fixation. When the locking component 4 is pressed down, it will abut the pressing rod 706, causing the pressing rod 706 to drive the clamping inclined block 707 to move downward. The clamping inclined block 707 drives the abutting post 705 and the clamping plate 704 to move, and the clamping plate 704 fixes the charging gun again, preventing displacement or shaking during locking. At the same time, when the pressing rod 706 loses its pressing force, the return spring 708 can make the pressing rod... 706 moves upward, and the clamping plate 704 disengages from the clamping and fixing of the charging gun; this device, through the setting of the clamping arc block 702, can automatically clamp the charging gun. Under the action of the clamping plate 704, a double fixing effect can be achieved to avoid clamping failure. At the same time, the two clamping plates 704 of this device can achieve synchronous and same distance automatic displacement, realizing the function of automatic positioning and automatic clamping of the charging gun. Moreover, the automatic positioning and clamping of this device can form a linkage effect with the locking component 4, automatically reinforcing before locking and automatically opening after locking, which is convenient for replacing the charging gun.

[0041] As attached Figure 5-6As shown, the locking component 4 includes a locking box 401 and a mounting box 402. The mounting box 402 is fixedly mounted on the top of the locking box 401, and the top of the mounting box 402 is fixedly connected to the output end of the drive cylinder 5. A drive gear plate 8 is fixedly mounted on one end of the bottom of the locking box 401. A locking cylinder 403 is rotatably connected inside the locking box 401. A bearing ring 404 is mounted on the outer wall of the locking cylinder 403 and is installed on the inner side wall of the locking box 401. External teeth 405 are provided on the outer wall of the locking cylinder 403. A drive shaft 406 is rotatably connected to the inner wall of the locking box 401. A drive gear 407 is fixedly mounted on the outer wall of the drive shaft 406 and meshes with the external teeth 405. The top of 406 is fixedly connected to the output end of the drive motor 408, which is fixedly mounted on the side wall of the mounting box 402. When locking, the device first moves downward by starting the drive cylinder 5. At this time, the drive cylinder 5 will drive the mounting box 402 and the locking box 401 to move downward. The locking cylinder 403 will automatically engage with the nut of the charging gun. At the same time, the drive motor 408 is started. Under the action of the drive shaft 406, the drive gear 407 drives the locking cylinder 403 to rotate, thereby automatically locking the nut. When the locking box 401 descends, the bottom of the locking box 401 will abut against the top of the pressing rod 706, thereby fixing the charging gun.

[0042] As attached Figure 7-8 As shown, a guide groove 409 is provided on the inner wall of the locking cylinder 403. A compensating rod 411 is slidably connected inside the guide groove 409. The compensating rod 411 is slidably connected inside the locking rod 410. The locking rod 410 is slidably connected inside the locking cylinder 403. A compensating spring 412 is fixedly installed at one end of the compensating rod 411. The other end of the compensating spring 412 is fixedly connected to the inner wall of the locking rod 410. The outer side of one end of the compensating rod 411 matches the nut.

[0043] As attached Figure 7As shown, a compression spring 413 is fixedly installed on the outer wall of the compensation rod 411. The compression spring 413 is located inside the guide groove 409. The other end of the compression spring 413 is fixedly connected to the inner wall of the guide groove 409. There are two locking rods 410, which are arranged opposite to each other. A locking wedge block 414 is slidably connected inside the locking cylinder 403. The thickness of the locking wedge block 414 increases from top to bottom. The inclined end of the locking wedge block 414 abuts against the outer wall of one end of the locking rod 410. A locking spring 415 is fixedly installed on the top of the locking wedge block 414. The other end of the locking spring 415 is fixedly connected to the inner top wall of the locking cylinder 403. A push post 416 is fixedly installed on the bottom of the locking wedge block 414. The other end of the push post 416 passes through the inner bottom wall of the locking cylinder 403 and is located on the outside. When the locking box 401 of this device descends, the abutment post 416 will abut against the top of the fixed box 7. Under the action of force, the abutment post 416 will move upward. At this time, under the action of the locking wedge block 414, it will abut against the two locking rods 410 and move relative to each other. The two locking rods 410 clamp the nut. Under the action of the rotation of the locking cylinder 403, the locking rods 410 rotate and lock the nut. The device, through the setting of the compensation rod 411, can make the locking rods 410 slide smoothly inside the locking cylinder 403. At the same time, the guide groove 409 plays a guiding role. The locking rods 410 can lock different nuts. After locking, it is easy to disassemble. The locking of this device can also be linked with the descent of the locking box 401.

[0044] As attached Figure 9 As shown, a rotating shaft 601 is fixedly installed at the bottom of the rotating disk 6, and a rotating bevel gear 602 is fixedly installed on the outer wall of the rotating shaft 601; a linkage shaft 603 is rotatably connected to the inner wall of the base 1, and a linkage bevel gear 604 is fixedly installed on the outer wall of one end of the linkage shaft 603. The linkage bevel gear 604 meshes with the rotating bevel gear 602, and a linkage gear 605 is unidirectionally driven connected to the outer wall of the other end of the linkage shaft 603. The linkage gear 605 meshes with the drive gear plate 8.

[0045] As attached Figure 10As shown, a through hole 606 is provided inside the linkage shaft 603. A one-way wedge 607 is slidably connected inside the through hole 606. One end of the one-way wedge 607 is triangular in shape. A compression spring 608 is fixedly installed at one end of the one-way wedge 607 inside the through hole 606. The other end of the compression spring 608 is fixedly connected to the inner wall of the through hole 606. A one-way groove 609 is provided on the inner wall of the linkage gear 605. The one-way groove 609 matches the one-way wedge 607. When the locking box 401 of this device descends and drives the drive gear plate 8 to move, the drive gear plate 8 will not drive the linkage shaft 603 to rotate. At this time, the inclined surface of the one-way wedge 607 is opposite to the inclined surface of the one-way groove 609. At this time, the rotation of the linkage gear 605 will not drive the linkage shaft 603 to rotate. The linkage shaft 603 rotates. To prevent the rotation of the rotating disk 6 during locking, the rotating disk 6 is kept in a stable state during locking to prevent deviations. When the locking box 401 moves upward to reset, the one-way inclined block 607 extends under the action of the compression spring 608. At this time, the straight surface of the one-way inclined block 607 is opposite to the straight surface of the one-way inclined groove 609. When the linkage gear 605 is driven to rotate by the driven tooth plate 8, the linkage gear 605 will drive the linkage shaft 603 to rotate. This enables the linkage shaft 603 to drive the rotating disk 6 to change the charging gun that is about to be locked, so that the device can automatically change the locked charging gun. At the same time, the change is linked with the action of the locking box 401.

[0046] As attached Figure 11 As shown, the upper part of the drive gear plate 8 is a smooth plate. Meshing teeth 801 are fixedly installed on the outer wall of the drive gear plate 8. A compensation gear plate 802 is slidably connected inside the drive gear plate 8. Compensation teeth 803 are provided on the outer wall of the compensation gear plate 802. The compensation teeth 803 are offset from the meshing teeth 801, and there are two compensation teeth 803. When it is necessary to control the number of teeth on the outer wall of the drive gear plate 8, the device can adjust the displacement of the compensation gear plate 802 to achieve automatic adjustment of the number of teeth. When the drive gear plate 8 drives the linkage gear 605 to rotate for a long time, in order to avoid the phenomenon of rotational difference, the device can compensate through the compensation gear plate 802 to ensure that both maintain the same rotation. The reset of the drive gear plate 8 can drive the rotating disk 6 to be replaced. At the same time, the upper part of the drive gear plate 8 is set as a smooth plate, which can prevent the rotating disk 6 from starting to rotate when the drive gear plate 8 begins to reset, preventing the rotating disk 6 from rotating before the locking cylinder 403 leaves the fixed box 7.
