[0027] Example 1

[0028] See attached Figure 1-4The utility model provides an electric tire bolt disassembling and assembling machine, including a telescopic cylinder 1, a telescopic rod 2, a telescopic control structure 3, a sleeve connector 4, a driving device, and a bolt sleeve 5. The lower end of the telescopic cylinder 1 is provided with an opening, and the telescopic cylinder 1 is sleeved outside the telescopic rod 2. The telescopic rod 2 is slidably connected to the telescopic cylinder 1. The telescopic rod 2 can move up and down in the telescopic cylinder 1 and extend out of the telescopic cylinder 1 from the opening at the lower end of the telescopic cylinder 1, but the telescopic rod 2 will not completely extend out of the telescopic cylinder 1 and separate from the telescopic cylinder 1. A strip-shaped through hole that passes through the front and back is provided in the middle of the telescopic rod 2. The telescopic rod 2 is provided with a rack 21 on one side wall in the strip-shaped through hole along the length direction of the strip-shaped through hole. The rack is used to control the displacement of the telescopic rod 2, and is therefore arranged on a single side wall. The telescopic control structure 3 includes a housing 31, a gear column 33, a locking member 34, and a spring 35. The housing 31 is fixedly connected to the lower end of the telescopic cylinder 1. The top and bottom of the housing 31 are respectively provided with a first opening and a second opening. The first opening is connected to the opening at the lower end of the telescopic cylinder 1. The second opening is for the telescopic rod 2 to pass through. The telescopic rod 2 can pass through the first opening and the second opening when it moves up and down. A limiting groove 340 is provided on the side wall of the housing 31 away from the telescopic rod 2. The limiting groove 340 is set as a groove with a cylindrical middle part and strips at both ends. The stopper 34 is set in the limiting groove 340. The stopper 34 is set in a plate shape. The two ends of the limiting groove 340 correspond to the shape of the stopper 34. The limiting groove 340 is used to prevent the stopper 34 from rotating. The gear column 33 is set inside the housing 31. The gear column 33 is meshed with the rack 21. The gear column 33 cooperates with the rack 21 to enable the telescopic rod 2 to move up and down. One end of the gear column 33 is fixedly connected to the stopper 34. The spring 35 is sleeved on the gear column 33. The two ends of the spring 35 respectively abut the telescopic rod 2 and the housing 31. Push the stopper 34 out of the limit slot 340 toward the telescopic rod 2, and then rotate the stopper 34, so that the stopper 34 can drive the gear column 33 to rotate, thereby causing the telescopic rod 2 to move up and down. When the stopper 34 is pushed out of the limit slot 340, the spring 35 is in a compressed state. After the telescopic rod 2 is displaced, the push on the stopper 34 is canceled, and the spring changes to an extended state, so that the stopper 34 can be pushed back to the limit slot 340, and the stopper 34 is restricted from rotating, and the gear column 33 cannot rotate, thereby fixing the telescopic rod 2 in a corresponding position. The sleeve connector 4 is rotatably connected to the lower end of the telescopic rod 2, and a fixing bolt 41 is provided on the outer side of the lower end of the sleeve connector 4, and the bolt sleeve 5 is connected to the lower end of the sleeve connector 4 through the fixing bolt 41. The sleeve connector 4 is used to install the drive device and the bolt sleeve 5, and the sleeve connector 4 and the bolt sleeve 5 cannot rotate relative to each other. The sleeve connector 4 can drive the bolt sleeve 5 to rotate synchronously under the drive of the drive device. The bolt sleeve 5 is used to be sleeved on the tire bolt, and the bolt sleeve 5 can drive the tire bolt to rotate, thereby loosening the tire bolt.

[0029] Preferably, the outer diameter of the spring 35 is greater than the width of the strip-shaped through hole, so as to ensure that the spring can abut between the telescopic rod 2 and the housing 31 . The spring 35 is preferably a flat wire spring.

[0030] Preferably, a rotation groove 330 is provided inside the housing 31, and the rotation groove 330 is located between the limiting groove 340 and the telescopic rod 2. The rotation groove 330 is preferably a cylindrical cavity structure with a circular cross-section in left view. The width of the rotation groove 330, that is, the height of the cylinder, is less than the length of the gear column 33, and the diameter of the rotation groove 330 is greater than the length of the stopper 34. When the spring 35 pushes the stopper 34 back to the limiting groove 340, the gear column 33 will move away from the telescopic rod along with the stopper 34. The width of the rotation groove 330 is less than the length of the gear column 33, which means that the distance that the gear column 33 can be displaced is less than the length of the gear column 33, and the gear column 33 can also mesh with the rack 21 when the stopper 34 is retracted into the limiting groove 340.

[0031] Preferably, the side wall of the housing 31 is provided with a third opening inside the limiting groove 340, and the locking member 34 is provided with a first knob 32 at the third opening, and one end of the first knob 32 away from the locking member 34 extends out of the housing 31 through the third opening. Pressing the first knob 32 can push the locking member 34 out of the limiting groove 340, and rotating the first knob 32 can drive the locking member to rotate synchronously. When the first knob 32 rotates, the portion of the first knob 32 extending into the housing 31 can rotate in the cylindrical area in the middle of the limiting groove 340.

[0032] Preferably, the driving device is arranged inside the lower end of the telescopic rod 2, the rotating shaft of the driving device is connected to the sleeve connector 4, and the driving device adopts a 25D370 micro reduction motor, the maximum torque of this type of motor is 26 Nm, which is sufficient for use in automobile maintenance. The driving device is fixedly connected to the telescopic rod 2, and the rotating shaft of the driving device is fixedly connected to the sleeve connector 4. When the rotating shaft of the driving device rotates, it can drive the sleeve connector 4 to rotate synchronously, and then drive the sleeve 5 sleeved on the bolt to rotate, so that the tire bolt can be screwed.

[0033] Preferably, the upper end of the telescopic cylinder 1 is connected with a gripping portion 8, and the gripping portion 8 includes a base, and a handle is provided at the top of the base. The base is set to be circular, and the handle is set to be rectangular.

[0034] Preferably, the fixing bolt 41 extends out of the sleeve connector 4, and the upper end of the bolt sleeve 5 is provided with a bolt hole corresponding to the fixing bolt 41. The sleeve connector 4 is sleeved on the upper end of the outer periphery of the sleeve 5, and the fixing bolt 41 extends from the sleeve connector 4 into the bolt hole of the bolt sleeve 5 to fix it, which can prevent the bolt sleeve 5 from being unable to rotate with the sleeve connector 4 due to the resistance of the tire bolt when the sleeve connector 4 drives the bolt sleeve 5 to rotate, and thus the tire bolt cannot be screwed. Moreover, the bolt sleeve 5 and the sleeve connector 4 are fixed by bolts, which facilitates the replacement of the bolt sleeve 5.

[0035] Working principle: When using the disassembly and assembly machine, first select the bolt sleeve 5 that meets the requirements, install the upper end of the bolt sleeve 5 into the lower end of the sleeve connector 4, extend the fixing bolt 41 into the bolt hole of the bolt sleeve 5 and tighten it, and fix the bolt sleeve 5 on the bolt connector 4. After the bolt sleeve 5 is installed, align the bolt sleeve 5 with the bolt hole on the wheel hub, press the first knob 32 to push the locking member 34 out of the limit groove 340, and the locking member 34 enters the rotation groove 330. Twist the first knob 32 to drive the gear column 33 to rotate, and the telescopic rod 2 extends out of the telescopic cylinder 1 as the gear column 33 rotates. When the bolt sleeve 5 can be sleeved on the tire bolt, loosen the first knob, so that the locking member 34 is pushed into the limit groove 340 under the action of the spring 35. Since the limit groove 340 is set in a bar shape, each rotation of the first knob is twisted 180°. After the locking member 34 returns to the limiting groove 340, the gear column 33 and the rack 21 are relatively stationary, and the telescopic rod 2 and the telescopic cylinder 1 are relatively fixed. Then, the gripping part is tightly grasped to press the disassembler to the wheel hub, so that the disassembler is close to the wheel hub, and the driving device is started. The driving device drives the bolt sleeve 5 to tighten the tire bolts. After the tire bolts are loosened, the driving device is turned off.

[0036] Example 2

[0037] See attached Figure 5-6 The present application provides a motor that is easy to install. Compared with Example 1, in order to make the disassembler more stable during use, a plurality of fixing plates 9 are provided in a ring matrix at the bottom of the handle 8. The fixing plates 9 can be placed on the wheel hub to support the disassembler and ensure that the disassembler will not tilt during use. The user only needs to press the disassembler against the bolt and does not need to manually maintain the balance of the disassembler.

[0038] Working principle: After the bolt sleeve 5 is installed, align the bolt sleeve 5 with the bolt hole on the wheel hub, place the lower end of the fixing plate 9 against the wheel hub, stably support the disassembler on the wheel hub, then adjust the distance that the telescopic rod 2 extends out of the telescopic tube 1, so that the bolt sleeve 5 is sleeved on the bolt, and then start the driving device to tighten the bolt sleeve 5. During the whole working process, the user only needs to press the disassembler against the bolt to ensure the stability of the disassembler, and then ensure that the bolt sleeve 5 can smoothly tighten the bolt, and there is no need to manually maintain the balance of the disassembler.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
