[0033] See also Figure 1 This embodiment is suitable for grinding the connection between the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120. If the grinding pressure is insufficient, insufficient grinding will occur, and the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120 will not match. If the grinding pressure is too high, excessive grinding will occur, and the gap between the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120 will be too large.

[0034] The connecting rod body 110 and the connecting rod cover 120 are assembled to form a connecting rod 100 , which includes a first end and a second end. The first end is provided with a first hole 101 , and the second end is provided with a second hole 102 . The second hole 102 is formed by combining the semicircular hole of the connecting rod body 110 and the semicircular hole of the connecting rod cover 120 .

[0035] See also Figures 1 to 3 This embodiment provides a grinding device 200, which is used to grind the connection between the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120. Specifically, the grinding device 200 includes a base 210, a lifting seat 220, an elastic component 230 and a driving component 240.

[0036] The base 210 is used to fix the connecting rod body 110 .

[0037] In a specific implementation, the base 210 is provided with a first positioning member 211 , a second positioning member 212 and a third positioning member 213 , and the first positioning member 211 , the second positioning member 212 and the third positioning member 213 define the installation position of the connecting rod body 110 .

[0038] Among them, the first positioning member 211 is adapted to the first hole 101, and one end of the second positioning member 212 abuts against the outer surface of the connecting rod body 110. Specifically, one end of the second positioning member 212 abuts against the outer surface of the second end. In this way, the connecting rod body 110 is initially positioned by the first positioning member 211 and the second positioning member 212. The third positioning member 213 and the surface of the base 210 clamp the connecting rod body 110, further realizing the secondary positioning of the connecting rod body 110 to prevent the connecting rod body 110 from shifting during the grinding process.

[0039] In this embodiment, the first positioning member 211 can be set as a positioning column, the extension direction of the positioning column is perpendicular to the surface of the base 210, the second positioning member 212 is a positioning pin, the extension direction of the positioning pin is parallel to the surface of the base 210, and the positioning pin and the positioning column are set at a preset angle. Under the joint limitation of the first positioning member 211 and the second positioning member 212, the connecting rod body 110 can be fixed on the base 210 in a preset placement state.

[0040] In this embodiment, the third positioning member 213 can also be set as a positioning piece, and the positioning piece and the outer surface of the base 210 jointly clamp the connecting rod body 110 to ensure that the connecting rod body 110 does not move forward and backward relative to the base 210. It can be understood that a certain friction force will be generated during the grinding process, and the clamping of the third positioning member 213 and the base 210 can offset the effect of the friction force, ensuring that the connecting rod body 110 always maintains a fixed position during the grinding process.

[0041] In actual use, the first positioning member 211 is inserted into the first hole 101 , the second positioning member 212 is abutted against the second end, and then the third positioning member 213 is fixed to the base 210 by screws.

[0042] The lifting seat 220 is provided with a receiving cavity for receiving the connecting rod cover 120, and the lifting seat 220 moves in a vertical direction relative to the connecting rod cover 120. To realize the lifting function of the lifting seat 220, the grinding device 200 further includes a hydraulic cylinder 250, which is installed on the base 210, and the output end of the hydraulic cylinder 250 is connected to the lifting seat 220.

[0043] There are two hydraulic cylinders 250, and the two hydraulic cylinders 250 are respectively installed on both sides of the elastic component 230. In this embodiment, the two hydraulic cylinders 250 are provided to improve the lifting stability of the lifting seat 220.

[0044] After the hydraulic cylinder 250 rises to the preset position, the connecting rod cover 120 located in the accommodating cavity can be replaced. After the hydraulic cylinder 250 descends to the preset position, the connecting rod cover 120 is placed in the accommodating cavity.

[0045] See also Figure 3 and Figure 4The elastic component 230 is installed between the lifting seat 220 and the connecting rod cover 120 .

[0046] Specifically, the elastic component 230 includes a hydraulic component 231, an elastic component 232 and a push-up component 233. The hydraulic component 231 is installed on the lifting seat 220, and the hydraulic component 231 is provided with an output end that can be extended and retracted in the vertical direction. The elastic component 232 is supported between the output end and the push-up component 233, and the push-up component 233 is used to push the connecting rod cover 120.

[0047] The elastic member 232 is configured as a spring, the hydraulic member 231 is configured as a hydraulic cylinder 250, and the spring is sleeved on the piston rod of the hydraulic cylinder 250. In this embodiment, the floating connection between the lifting seat 220 and the connecting rod cover 120 is achieved through the combination of the hydraulic member 231, the elastic member 232 and the abutting member 233, and the grinding effect is improved by adjusting the grinding pressure, so that the matching degree between the connecting rod body 110 and the connecting rod cover 120 is higher.

[0048] When the grinding pressure is insufficient, the extension length of the hydraulic component 231 is appropriately increased, and when the grinding pressure is too large, the extension length of the hydraulic component 231 is appropriately shortened, so that the adjustment is more flexible.

[0049] Please continue reading Figures 1 to 3 The driving assembly 240 is mounted on the base 210 and is provided with a driving end, which abuts against the connecting rod cover 120 and drives the connecting rod cover 120 to move horizontally relative to the connecting rod body 110, thereby grinding the connection between the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120.

[0050] After the tooth surfaces of the connecting rod body 110 and the connecting rod cover 120 are continuously ground against each other, the fit between the connection points of the two is gradually improved, so that the ground connection points meet the assembly standards.

[0051] The driving assembly 240 includes a driving member 241 and a transmission member 242 . The driving member 241 is mounted on the base 210 . The transmission member 242 is connected to an output end of the driving member 241 , and the transmission member 242 is provided with a driving end.

[0052] In some embodiments, the base 210 is provided with a guide rail fixing block 214, and the transmission member 242 is provided with a slider 2421, which is slidably connected to the guide rail fixing block 214 in a horizontal direction. This embodiment limits the grinding direction by means of a sliding connection to prevent the grinding angle from deviating.

[0053] Based on the above content, the use principle of the grinding device 200 in this embodiment is further described as follows:

[0054] S100 . Place the connecting rod body 110 on the base 210 , and position it by means of the first positioning member 211 , the second positioning member 212 , and the third positioning member 213 .

[0057] S400. Adjust the extension length of the hydraulic component 231 so that the pressure provided by the abutment component to the connecting rod cover 120 is appropriate.

[0058] S500 . Start the driving member 241 to drive the transmission member 242 and the connecting rod cover 120 to move in the horizontal direction, and grind the connection between the tooth surface of the connecting rod cover 120 and the connecting rod body 110 .

[0059] During the grinding process, this embodiment uses an elastic connection to allow the connecting rod cover 120 to be subjected to a floating force, which can ensure the grinding effect on one hand, and avoid appearance damage caused by hard contact on the other hand, thereby improving the aesthetics.
