In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 1-6 As shown, an embodiment of the present invention provides a slag removal device for a broken connecting rod, comprising a working box 1, wherein an installation cavity 101 is provided in the working box 1, which can be used to place some electrical components; a working plate 2 is provided on the upper side wall of the working box 1, and the working plate 2 is provided with a positioning and holding assembly 3, which is used to fix the broken connecting rod on the working plate 2; a vibration device 4 is also provided on the working plate 2, and the vibration device 4 can be an attached vibrator. When the broken connecting rod is fixed on the working plate 2, the vibration device 4 can be started, and the vibration device 4 vibrates the working plate 2 and drives the connecting rod to vibrate, thereby shaking off the residual slag at the broken surface of the connecting rod, thereby achieving the purpose of slag removal. However, although the above-mentioned short-term vibration by the vibration device 4 can remove most of the residual slag at the expanded section, it can only loosen some residual slag with strong adhesion but may not be removed. Therefore, a slag blowing assembly 5 is provided on the upper side wall of the working box 1, wherein the slag blowing assembly 5 is used to blow off the slag at the expanded section of the connecting rod, and cooperate with the vibration surface of the vibration device 4. For the residual slag loosened after vibration, it can be directly blown off by the slag blowing assembly 5, so as to achieve the purpose of complete slag removal; in order to facilitate the movement of the slag blowing assembly 5, a driving assembly 6 is also provided on the upper side wall of the working box 1, which is used to move the wind knife device 59 in the slag blowing assembly 5 close to or away from the connecting rod on the working plate 2, so as to facilitate the placing of the connecting rod on the working plate 2 from above and fix it by the positioning clamping assembly.

The end of the pressing block is rotatably connected with the drive shaft of the second linear drive device 351, and the middle part is rotatably connected with the end of the pull plate 352 away from the mounting block through a rotating shaft, so that the pull plate 352 can be driven to rotate away from the end of the second linear drive device 351 through the second linear drive device 351, and finally the end of the pressing plate 353 abuts against and presses down the upper side wall of the connecting rod. In this embodiment, the pressing plate 353 presses down the upper side wall of the large head hole of the connecting rod, because the expansion section at the large head hole of the connecting rod is subjected to residual slag treatment, and there are two pressing assemblies 35, so that the connecting rod has two pressing points, which is more stable. Specifically, the linear drive device is a cylinder.

[0051] Specifically, in order to cushion the vibration generated by the vibration device 4, a shock-absorbing support assembly 7 is also provided on the work box 1, wherein the work plate 2 is spaced apart from the upper side wall of the work box 1, the vibration device 4 is installed on the lower side wall of the work plate 2, and the work plate 2 and the work box 1 are connected through the shock-absorbing support assembly 7. The vibration device 4 drives the work plate 2 to vibrate, which will be transmitted to the work box 1. The shock-absorbing support assembly 7 can greatly reduce the vibration frequency transmitted to the work box 1.

[0052] Specifically, in the present embodiment, the shock-absorbing support assembly 7 includes a plurality of shock-absorbing sub-assemblies, and the plurality of shock-absorbing sub-assemblies are arranged at the four corners of the working plate 2 to evenly bear force and stably support the working plate 2; wherein the shock-absorbing sub-assemblies include a connecting column 71, an elastic member 72, a fixing sleeve 73 and a fastener 74, and a mounting hole is opened on the working plate 2, and the fixing sleeve 73 is interference-fitted in the mounting hole, thereby increasing the connection strength at the mounting hole, and the lower end of the connecting column 71 is mounted on the upper side wall of the working box 1 by bolts, and the upper end of the connecting column 71 passes through the fixing sleeve 73 and is located above it, and the two are slidably connected, and the elastic member 72 is sleeved on the outside of the connecting column 71 and is located between the fixing sleeve 73 and the lower end of the connecting column 71, so as to play a buffering role, and the fastener 74 is threadedly connected to the upper end of the connecting column 71, so as to play a locking role.

In addition, a first positioning rod 10 and a second positioning rod 11 are provided on the outer side of the partition plate. The first positioning rod 10 and the second positioning rod 11 and the inner wall of the working box 1 surround a placement area, and the slag box 8 is placed in the placement area to prevent the slag box 8 from moving out of the collection area when the working box 1 vibrates, causing the residual slag to fall onto the partition plate. In this way, the slag box 8 does not need to be fixed, but only needs to be placed in the placement area. When the residual slag needs to be cleaned, the slag box 8 can be taken out.

[0055] Specifically, in the present embodiment, a switch 12 is further provided on the upper side wall of the working box 1. Correspondingly, corresponding control components and wiring are provided in the inner cavity of the working box 1 to connect the switch 12 and various electrical components provided above the working box 1.
