[0037] The grinding device 100 includes a base 110 , a cover 130 , and a driving assembly 120 .

[0038] The base 110 is used to fix the connecting rod body 200 and make the first tooth surface 201 face the second tooth surface 211 .

[0039] See also Figure 1 and Figure 2 The base 110 includes a bearing member 111 and a support member 112; one end of the support member 112 is vertically fixed to one side of the bearing member 111; the end of the support member 112 away from the bearing member 111 has a mounting groove 1121; a fixing platform 121 is arranged in the mounting groove 1121; the driving assembly 120 is arranged on the fixing platform 121.

[0041] A fixing groove is formed on the inner wall of the installation groove 1121 ; the fixing platform 121 is fixed in the fixing groove so that the fixing platform 121 is fixedly connected to the support member 112 .

[0042] In some embodiments, the base 110 further includes a positioning member 113 ; the positioning member 113 is disposed on one side of the support member 112 and protrudes from an outer surface of the support member 112 ; the positioning member 113 is used to position one end of the connecting rod body 200 away from the connecting rod cover 210 .

[0043] The shape of the positioning member 113 matches the shape of one end of the connecting rod body 200 away from the connecting rod cover 210 ; the end of the connecting rod body 200 away from the connecting rod cover 210 can be sleeved on the positioning member 113 .

[0044] In some embodiments, the base 110 also includes a fixing member 114 and a limiting member 115; the fixing member 114 and the positioning member 113 are arranged on the same side of the support member 112; one end of the fixing member 114 is fixed to the support member 112; the limiting member 115 is passed through the fixing member 114, and one end of the limiting member 115 is facing the connecting rod body 200 close to one end of the connecting rod cover 210.

[0045] The fixing member 114 is used to support the limiting member 115 so that the limiting member 115 is close to one end of the connecting rod body 200, which can limit the rotation of the connecting rod body 200 with the positioning member 113 as the rotation center, thereby ensuring that when the connecting rod body 200 is fixed on the base 110, the first tooth surface 201 always faces the second tooth surface 211.

[0046] In some embodiments, the limiting member 115 is adjustably disposed on the fixing member 114 .

[0047] Exemplarily, the fixing member 114 is provided with an adjustment hole, the inner wall of the adjustment hole is provided with an internal thread, and the outer surface of the limiting member 115 is provided with an external thread corresponding to the internal thread; the limiting member 115 cooperates with the inner wall thread of the adjustment hole.

[0048] The limiting member 115 cooperates with the inner wall thread of the adjusting hole to adjust the position of the connecting rod body 200 away from one end of the positioning member 113 to ensure that the first tooth surface 201 faces the second tooth surface 211 .

[0049] In some embodiments, the base 110 further includes a reinforcing member 118 ; the reinforcing member 118 is respectively connected to the bearing member 111 and the supporting member 112 . The reinforcing member 118 is used to enhance the supporting strength of the base 110 .

[0050] In some embodiments, the base 110 includes two reinforcement members 118 ; the two reinforcement members 118 are symmetrically disposed on both sides of the support member 112 .

[0051] In some embodiments, the grinding device 100 further includes a pressing member 117 ; the pressing member 117 is detachably connected to the base 110 ; a limiting space is provided between the pressing member 117 and the base 110 ; the limiting space is used to accommodate the connecting rod body 200 .

[0052] When one end of the connecting rod body 200 is sleeved on the positioning member 113 and the other end is abutted against the limiting member 115, the clamping member 117 can press the connecting rod body 200 against one side of the supporting member 112 to prevent the connecting rod body 200 from shifting when the first tooth surface 201 and the second tooth surface 211 are ground.

[0053] Exemplarily, the pressing member 117 is detachably connected to the supporting member 112 via a bolt structure.

[0054] In some embodiments, the base 110 also includes a mating piece 116, and the mating piece 116 and the positioning piece 113 are located on the same side of the support piece 112; one side of the mating piece 116 is connected to one side of the support piece 112; the shape of the mating piece 116 away from the support piece 112 matches the shape of the end of the connecting rod body 200 away from the positioning piece 113.

[0055] The limiting space is provided between the matching member 116 and the pressing member 117. The pressing member 117 and the matching member 116 are detachably connected via a bolt structure.

[0056] See also Figure 1 and Figure 4 The driving assembly 120 is disposed on the fixing platform 121; the cover sleeve 130 is disposed above the driving assembly 120. The cover sleeve 130 is used to accommodate the connecting rod cover 210. The driving assembly 120 is used to drive the cover sleeve 130 to reciprocate, so that the connecting rod cover 210 in the cover sleeve 130 reciprocates on the connecting rod body 200, thereby causing the first tooth surface 201 and the second tooth surface 211 to grind against each other.

[0057] See also Figure 1 and Figure 3 The driving component 120 includes a guide rail 122, a moving member 124, a first elastic member 125, a second elastic member 126 and a driving member 127; the guide rail 122 is arranged on the fixed platform 121; the moving member 124 is slidably matched with the guide rail 122; the first elastic member 125 and the second elastic member 126 are respectively arranged on both sides of the cover sleeve 130; one end of the first elastic member 125 is connected to an end of the moving member 124 away from the second elastic member 126, and the other end is connected to a side of the cover sleeve 130 away from the second elastic member 126; one end of the second elastic member 126 is connected to an end of the moving member 124 away from the first elastic member 125, and the other end is connected to a side of the cover sleeve 130 away from the first elastic member 125; the output end of the driving member 127 is connected to the moving member 124.

[0058] The driving member 127 can drive the moving member 124 to reciprocate on the guide rail 122. When the moving member 124 reciprocates on the guide rail 122, the cover sleeve 130 can reciprocate along the extension direction of the guide rail 122 driven by the first elastic member 125 and the second elastic member 126, thereby causing the connecting rod cover 210 to reciprocate on the connecting rod body 200.

[0059] When the connecting rod cover 210 reciprocates on the connecting rod body 200 , the first tooth surface 201 and the second tooth surface 211 can rub against each other to improve the tooth profile matching degree between the first tooth surface 201 and the second tooth surface 211 .

[0060] Exemplarily, the first elastic member 125 and the second elastic member 126 are both springs.

[0061] Exemplarily, the driving member 127 is a cylinder, the output end of the cylinder is a telescopic rod, and an automatic reversing valve is provided inside the cylinder.

[0062] In some embodiments, the driving assembly 120 also includes a slider 123; the slider 123 slidably cooperates with the guide rail 122; the side of the slider 123 away from the guide rail 122 is connected to the moving member 124 so that the moving member 124 can slidably cooperate with the guide rail 122.

[0063] Furthermore, the driving assembly 120 includes two sliders 123 , the two sliders 123 are respectively slidably matched with the guide rails 122 , and the two sliders 123 are respectively connected to two ends of the moving member 124 .

[0065] In some embodiments, the driving assembly 120 includes two first elastic members 125 and two second elastic members 126 to improve the ability of the cover sleeve 130 to reciprocate along the extending direction of the guide rail 122 .

[0066] In some embodiments, the driving assembly 120 further includes a connecting member 128; the connecting member 128 is connected to the output end of the driving member 127 and fixed to the moving member 124. The output end of the driving member 127 drives the moving member 124 to reciprocate on the guide rail 122 through the connecting member 128.
