For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0043] like Figure 1-6 As shown, an embodiment of the utility model 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, the above-mentioned short-term vibration by the vibration device 4 can remove most of the residual slag at the expanded section, but for some residual slag with strong adhesion, it can only loosen it, but may not be able to remove it. 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. The loosened residual slag after vibration 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, the upper side wall of the working box 1 is also provided with a driving assembly 6, 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.

[0044] Specifically, such as Figure 2-3As shown, the slag blowing assembly 5 includes a mounting plate 51, a swinging mechanism and a wind knife device 59, wherein the wind knife device 59 is located above the connecting rod, and the air outlet is facing the expansion section of the connecting rod. The wind knife device 59 is an existing device, which is connected to the external air pipe. By blowing air to the expansion section of the connecting rod, the residual slag on the expansion section falls off, and the wind knife device 59 is connected to the output end of the swinging mechanism and the external air pipe. The swinging mechanism is installed on the mounting plate 51, and the mounting plate 51 is installed on the upper side wall of the working box 1. The wind knife device 59 can swing and blow air under the drive of the swinging mechanism. During the swinging process, the wind direction of the air outlet at the lower end of the wind knife device 59 can form different angles with the vertical expansion section of the connecting rod, thereby stably blowing off the residual slag with different degrees of looseness at the expansion section. Specifically, the mounting plate 51 is slidably mounted on the upper side wall of the working box 1. The driving end of the driving assembly 6 is connected to the mounting plate 51. Driven by the driving assembly 6, the mounting plate 51 is moved toward or away from the working plate 2, and the air knife device 59 is moved toward or away from the expansion section of the connecting rod, thereby facilitating the positioning and installation of the connecting rod on the working plate 2. Specifically, the air knife device 59 is an existing device.

[0045] Through the cooperation of the above-mentioned vibration device 4 and the slag blowing component 5, during use, the vibration device 4 is first vibrated for a certain period of time to remove most of the residual slag on the expanded section and loosen the residual slag with strong adhesion, and then the slag blowing component 5 is used to blow air to further remove these residual slag, so as to achieve the purpose of completely removing the residual slag on the expanded section. Compared with using the vibration device 4 to vibrate alone, the time for complete removal is shorter; and the wind knife device 59 in the slag blowing component 5 is swinging blowing, and the direction of the swinging blowing will form an angle with the expanded section. Compared with continuing to vibrate, it is easier to blow off the loosened residual slag, thereby ensuring that the residual slag is completely removed.

[0046] Specifically, the drive assembly 6 includes a first linear drive device 61 and a drive plate 62. A slide rail 63 is provided on the upper side wall of the work box 1, and a slider 64 is provided on the slide rail 63. The mounting plate 51 is connected to the slider 64.

The first linear drive device 61 drives the mounting plate 51 toward or away from the work plate 2 via the slider 64. Specifically, the first linear drive device 61 can be a cylinder.

[0047] Specifically, the swing mechanism includes a rotating motor 52, a turntable 53, a driving rod 54, a rotating shaft 55 and a connecting plate 56, wherein the rotating motor 52 is mounted on an end surface of the mounting plate 51 away from the working plate 2, the output shaft of the rotating motor 52 passes through the mounting plate 51 and is connected to the turntable 53, the driving rod 54 is eccentrically arranged on the side wall close to the turntable 53, and the output shaft of the rotating motor 52 is spaced apart from the driving rod 54, so that the turntable 53 and the driving rod 54 form an eccentric wheel mechanism, correspondingly, the connecting plate 56 is mounted on the upper side wall of the wind knife device 59, and the connecting plate A first sliding hole 57 is provided in the side wall of the rotating disk 56.

During operation, the rotating motor 52 is activated, the rotating disk 53 rotates, and the driving rod 54 slides within the first sliding hole 57, driving the connecting plate 56 to rotate about the rotating shaft 55. Ultimately, the wind knife device 59 swings back and forth about the rotating shaft 55, causing the air outlet of the wind knife device 59 to continuously change direction. In this embodiment, the axis of the output shaft of the rotating motor 52 coincides with the central axis of the rotating disk 53, and the driving rod 54 is fixed to the side wall of the rotating disk 53, making the driving process more stable.

[0048] Specifically, in this embodiment, the connecting plate 56 is configured as a U-shaped plate, with a first sliding hole provided on a side wall of the U-shaped plate near the mounting plate 51. The end of the rotating shaft 55, away from the mounting plate 51, sequentially passes through the two side walls of the U-shaped plate and is rotatably connected, thereby forming two connection points between the rotating shaft 55 and the connecting plate 56, which provides more stable rotation. Specifically, a bearing is provided on the rotating shaft 55, which achieves a rotational connection between the rotating shaft 55 and the connecting plate 56 via the bearing. Similarly, a bearing is also provided on the end of the driving rod 54, which achieves a sliding and rotational connection with the first sliding hole 57 via the bearing. The first sliding hole 57 is provided on a side wall of the U-shaped plate near the turntable 53.

[0049] Specifically, in order to facilitate the adjustment of the height of the entire wind knife device 59, thereby adjusting the swinging blowing range of the wind knife device 59, in this embodiment, a second sliding hole 58 is provided on the mounting plate 51. The second sliding hole 58 is vertically arranged, and the end of the rotating shaft 55 is detachably mounted on the second sliding hole 58 through two nuts. When the height needs to be adjusted, it is only necessary to operate the two nuts to change the position height of the end of the rotating shaft 55 fixed on the second sliding hole 58.

[0050] Specifically, in order to realize the positioning and holding of the connecting rod, the positioning and holding assembly 3 includes a small head positioning member, a large head positioning member and a holding assembly 35; the small head positioning member is used to position the small head of the connecting rod. In this embodiment, the small head positioning member includes a small head positioning block 31, which is mounted on the working plate 2 by bolts. The small head positioning block 31 is provided with a V-shaped through groove near the end face of the connecting rod, and the outer side wall of the small head of the connecting rod contacts the two side walls of the V-shaped through groove to complete the positioning of the small head of the connecting rod; the large head positioning member includes a positioning column 32, and the large head hole of the connecting rod is sleeved on the positioning column 32 to complete the positioning of the large head of the connecting rod, and correspondingly, a large head support plate 33 and a small head support block 34 are also provided on the working plate 2, and the large head support plate 33 is mounted on the working plate 2 by bolts, and the positioning column 32 is mounted on the upper side wall of the large head support plate 33. After the positioning of the connecting rod is completed, the large head of the connecting rod is placed on the large head support plate 33, and the small head of the connecting rod Placed on the small head support block 34; the holding assembly 35 includes a pressing block, a mounting block and a second linear drive device 351. The second linear drive device 351 is mounted on the working plate 2, and the drive shaft is set upward. The mounting block is mounted on the second linear drive device 351 by bolts and is rotatably connected to the pull plate 352 via a rotating shaft. The end of the pressing block is rotatably connected to the drive shaft of the second linear drive device 351, and the middle part is rotatably connected to the end of the pull plate 352 away from the mounting block via a rotating shaft. Therefore, 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. 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 end hole of the connecting rod because the expansion section at the large end hole of the connecting rod is subjected to residual slag treatment. In addition, there are two holding assemblies 35, so that the connecting rod has two holding 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, and the vibration device 4 is installed on the lower side wall of the work plate 2. 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 this 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-assembly includes a connecting column 71, an elastic member 72, a fixing sleeve 73 and a fastener 74. A mounting hole is opened on the working plate 2, and the fixing sleeve 73 is interference-mounted in the mounting hole, thereby increasing the connection strength at the mounting hole. The lower end of the connecting column 71 is mounted on the upper side wall of the working box 1 by a bolt, 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. 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 to play a buffering role. The fastener 74 is threadedly connected to the upper end of the connecting column 71 to play a locking role.

[0053] Specifically, to further reduce vibrations affecting the working box 1, a first washer 75 and a second washer 76 are sleeved onto the outer sidewall of the connecting column 71. The first washer 75 is positioned between the elastic member 72 and the upper sidewall of the lower end of the connecting column 71, while the second washer 76 is positioned between the fastener 74 and the upper sidewall of the fixing sleeve 73. Both the first and second washers 75 and 76 are elastic, thus providing a buffering effect. When the fastener 74 is tightened, it abuts and compresses the second washer 76, thereby creating a greater preload force and enhancing the locking effect of the fastener 74. Furthermore, the natural frequencies of the first and second washers 75 and 76 are greater than the natural frequencies of the elastic member 72. This prevents resonance between the two and reduces the shock absorption effect, while also increasing the frequency of external interference forces and reducing the vibration amplitude of the working box 1. Because the vibration amplitude decreases as the frequency of the interference force increases, the addition of the washers serves to make the interference force frequency significantly greater than the natural frequency of the vibration device 4, thereby reducing the vibration amplitude. Specifically, the first and second washers 75 and 76 are made of polyethylene.

[0054] Specifically, in order to better remove slag and prevent the residual slag at the expansion section of the connecting rod from falling and making the entire working surface messy, a slag box 8 is provided on the partition plate in the inner cavity of the working box 1, and a guide channel 9 is provided at the upper end of the slag box 8. The working plate 2 is provided with a slag removal through-hole 21 located below the large end expansion section of the connecting rod. In this embodiment, the slag removal through-hole 21 extends upward and passes through the large end support plate 33 and the positioning column 32 in sequence. Correspondingly, the upper end of the guide channel 9 passes upward through the upper side wall of the working box 1 and is connected to the lower side wall of the working plate 2, and the guide channel 9 is connected to the slag removal through-hole 21, so that the residual slag falling from the expansion section of the connecting rod will fall into the slag removal through-hole 21 and be collected into the slag box 8 in the working box 1 through the guide channel 9, so as to prevent the residual slag from falling randomly during the processing, so that after the slag removal is completed, it has to be cleaned up, which is time-consuming and labor-intensive. 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 this 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 the various electrical components provided above the working box 1. The specific connection relationship will not be repeated here, and they are all existing. The slag removal work of the entire equipment can be controlled by the switch 12, which is more convenient.

[0056] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
