DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0029] Embodiment 1:

[0030] like Figure 1-2 As shown, an automatic sleeve switching mechanism for a heavy vehicle rim is provided, which is used to switch the tightening sleeve 5 on the rim tightening mechanism 3 of the heavy vehicle. The automatic sleeve switching mechanism includes a tightening sleeve storage position 2 for placing the tightening sleeve 5, a clamping assembly 9 arranged on the tightening sleeve storage position 2 for clamping the tightening sleeve 5, a sensing assembly arranged on the tightening sleeve storage position 2 and used to sense whether the tightening sleeve 5 is displaced into place, and a moving assembly 10 arranged on the tightening sleeve storage position 2 and used to move the tightening sleeve 5 up or down. Exemplarily, for the convenience of induction, the tightening sleeve storage position 2 for placing tightening sleeves 5 of different models and types is also arranged on the tightening sleeve storage position bracket 11.

[0031] In the present technical solution, when the tightening sleeve 5 is disassembled, when the induction component senses that the tightening sleeve 5 moves to the tightening sleeve storage position 2, the clamping component 9 fixes the tightening sleeve 5, and after the induction component senses that the tightening sleeve 5 is clamped, the moving component 10 descends to drive the tightening sleeve 5 to move downward, and the tightening connecting rod 4 and the tightening sleeve 5 are separated, and the separated tightening sleeve 5 is placed in the tightening sleeve storage position 2. When the tightening sleeve 5 is installed, when the tightening connecting rod 4 moves to the tightening sleeve storage position 2, the moving component 10 rises to drive the tightening sleeve 5 to move upward, so that the tightening sleeve 5 and the tightening connecting rod 4 are assembled into one.

[0032] In this embodiment, the heavy vehicle rim tightening mechanism 3 includes a tightening connecting rod 4 and a tightening sleeve 5 connected to one end of the tightening connecting rod 4 and used to tighten the bolts or nuts on the heavy vehicle rim. A spring and a marble 6 connected to the spring are provided on one end of the tightening connecting rod 4 connected to the tightening sleeve 5, and a hole groove matching the marble 6 is provided on the tightening sleeve 5. The tightening connecting rod 4 and the tightening sleeve 5 are mechanically fixed by the marble 6, which is convenient for installation and disassembly.

[0033] In this embodiment, the sensing component includes an inductive sensor 7 for sensing whether the tightening sleeve 5 is vertically positioned in the tightening sleeve storage position 2 and a magnetic sensor 8 for sensing whether the tightening sleeve 5 is clamped. Exemplarily, the inductive sensor 7 is an eddy current sensor. Once the tightening sleeve 5 is placed in the tightening sleeve storage position 2, an induced current will be generated in the tightening sleeve storage position 2. Exemplarily, the magnetic sensor 8 is a TMR sensor element. By providing a magnet on the tightening sleeve 5, as the tightening sleeve 5 is continuously clamped by the clamping component 9, the direction of the magnetic field detected by the TMR sensor element also changes. By measuring the output voltage of the TMR sensor element, it is analyzed whether the tightening sleeve 5 is clamped.

[0034] In this embodiment, the clamping assembly 9 is a clamping cylinder. The moving assembly 10 is a push-pull cylinder, and the push-pull cylinder moves vertically up and down.

[0035] In this embodiment, the automatic sleeve switching mechanism further comprises a PLC controller connected to the tightening sleeve storage position 2. The automation of the tightening sleeve storage position 2 is controlled by the PLC controller to improve the operation efficiency.

[0036] Embodiment 2:

[0037] like Figure 3-4As shown, this embodiment provides a tightening device for an automatic switching sleeve for a heavy vehicle rim, comprising the automatic switching sleeve mechanism and the heavy vehicle rim tightening mechanism 3 as shown in Example 1, the heavy vehicle rim tightening mechanism 3 comprising a tightening connecting rod 4 and a tightening sleeve 5 connected to one end of the tightening connecting rod 4, a spring and a marble 6 connected to the spring are provided on the end of the tightening connecting rod 4 connected to the tightening sleeve 5, and a hole groove matching the marble 6 is opened on the tightening sleeve 5.

[0038] Exemplarily, the other end of the tightening connecting rod 4 is connected to the robot 1 to realize automated tightening switching operation during operation.

[0039] The disassembly process of the utility model is as follows:

[0040] (1) The robot 1 drives the heavy vehicle rim tightening mechanism 3 to move vertically downward to above the empty sleeve storage position 2, and the axes of all tightening sleeves on the heavy vehicle rim tightening mechanism 3 are completely coincident with the axes of the empty sleeve storage position 2.

[0041] (2) The robot 1 drives the heavy vehicle rim tightening mechanism 3 to vertically insert the tightening sleeve 5 into the empty sleeve storage position 2. At this time, the inductive sensor 7 detects that the tightening sleeve 5 is vertically in place, generating a predetermined current change. Subsequently, the PLC controller notifies the clamping cylinder to clamp all the tightening sleeves 5.

[0042] (3) When the magnetic sensor 8 detects that the tightening sleeve 5 is clamped in place, the PLC controller notifies the push-pull cylinder to move downward. At the same time, the push-pull cylinder pulls the tightening sleeve 5 off the tightening connecting rod 4 through the clamping claw, and the marble 6 between the two is positioned and disengaged. After the push-pull cylinder moves downward into place, the PLC controller notifies the robot 1 to lift up the heavy vehicle rim tightening mechanism 3, and the tightening sleeve 5 is disassembled. At the same time, all tightening sleeves 5 are clamped and retained in the sleeve storage position 2.

[0043] The installation process of the utility model is as follows:

[0044] (1) According to the process recipe, the robot 1 moves the heavy vehicle rim tightening mechanism 3 to above the sleeve storage position 2 where the tightening sleeve 5 model needs to be switched.

[0045] (2) The robot 1 moves the heavy vehicle rim tightening mechanism 3 vertically downward to insert the tightening connecting rod 4 into the sleeve storage position 2. After being vertically inserted into place, the robot 1 notifies the PLC controller that the tightening connecting rod 4 has been vertically positioned. At the same time, the PLC controller notifies the push-pull cylinder to move upward, pushing the tightening sleeve 5 and the tightening connecting rod 4 to be positioned through the marble 6 slot and re-forming a whole.

[0046] (3) The PLC controller notifies the clamping cylinder 9 to loosen, and the magnetic sensor 8 detects a position signal. Subsequently, the PLC controller notifies the robot 1 to lift the heavy vehicle rim tightening mechanism 3 upwards, and the tightening sleeve 5 is now installed.

[0047] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
