DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] In the technical scheme, a vehicle connector grinding device includes a fixing plate 1, a sandblasting machine 2 and a vehicle connector 3, a fixing ring 4 is installed on the side wall of the fixing plate 1, the sandblasting machine 2 is installed in the fixing ring 4, a motor is installed on the side wall of the fixing plate 1, the motor is electrically connected to an external power supply, a connecting plate 6 is installed on the output end of the motor, and clamping mechanisms 7 are installed on the left and right sides of the lower wall of the connecting plate 6, and the two clamping mechanisms 7 are clamped on the outside of the vehicle connector 3;

[0023] The clamping mechanism 7 includes a first clamping plate 71, a second clamping plate 72, an electric control push rod 73 and a connecting block 74. The first clamping plate 71 is installed on the lower wall of the connecting plate 6. The lower wall of the connecting plate 6 is provided with a slide groove 8. The second clamping plate 72 is slidably installed in the slide groove 8. The inner cavity of the connecting plate 6 is provided with an electric control push rod 73. The electric control push rod 73 is electrically connected to an external power supply. One end of the connecting block 74 is installed on the output end of the electric control push rod 73. The other end of the connecting block 74 is connected to the side wall of the second clamping plate 72.

[0024] In this technical solution, both clamping mechanisms 7 can clamp the automobile connector 3. When the sandblasting machine 2 is started for sandblasting and grinding, the two clamping mechanisms 7 are opened alternately, so that the automobile connector 3 does not fall off, and the sandblasting machine 2 can sandblast and grind the part blocked by the first clamping plate 71 and the second clamping plate 72, thereby avoiding the occurrence of grinding dead angles and improving the grinding efficiency.

[0025] In addition, the motor can drive the connecting plate 6 to rotate, so that the angle of the automobile connecting part 3 can be adjusted without manual adjustment.

[0026] In some technical solutions, a protective cover shell 9 is installed on the side wall of the fixed plate 1, and the protective cover shell 9 is connected to the outside of the motor. A sealing ring 10 is installed on the inner wall of the protective cover shell 9, and the sealing ring 10 is in contact with the side wall of the motor output end.

[0027] In this technical solution, the protective cover shell 9 can shield the motor, thereby preventing the steel shots sprayed by the sandblasting machine 2 from contacting the motor and causing damage to the motor. The sealing ring 10 can seal the lower wall of the protective cover shell 9 to prevent the steel shots from splashing into the protective cover shell 9.

[0028] In some technical solutions, a shielding mechanism 11 is installed in the inner cavity of the connecting plate 6. There are two shielding mechanisms 11 in total. The two shielding mechanisms 11 are respectively arranged on both sides of the two slide grooves 8. The shielding mechanism 11 can shield the slide grooves 8, and the second clamping plate 72 passes through the lower wall of the shielding mechanism 11.

[0029] In this technical solution, since a slide groove 8 is provided on the lower wall of the connecting plate 6, in order to prevent steel shots from entering the interior of the connecting plate 6, it is necessary to set a shielding mechanism 11 to shield the slide groove 8, thereby preventing steel shots from entering and affecting the operation of the electric control push rod 73.

[0030] In some technical solutions, the shielding mechanism 11 includes a main roller 111, a secondary roller 112 and an annular belt 113. The main roller 111 and the secondary roller 112 are respectively arranged on the left and right sides of the slide groove 8. The annular belt 113 is sleeved on the outside of the main roller 111 and the secondary roller 112. A connecting hole 12 is opened on the side wall of the annular belt 113, and the second clamping plate 72 passes through the lower wall of the annular belt 113 through the connecting hole 12.

[0031] In this technical solution, the lower wall of the annular belt 113 will fit with the inner wall of the connecting plate 6. When the electric control push rod 73 drives the second clamping plate 72 to move, the annular belt 113 will also move with the second clamping plate 72, thereby ensuring that the slide groove 8 is always in a closed state, and this closed form will not interfere with the movement of the second clamping plate 72.

[0032] In some technical solutions, the side walls of the first clamping plate 71 and the second clamping plate 72 are both provided with anti-slip patterns 13 .

[0033] In this technical solution, the anti-skid pattern 13 can be provided to increase the friction between the first clamping plate 71 and the second clamping plate 72 and the automobile connecting part 3, thereby preventing the automobile connecting part 3 from falling off.

[0034] In some technical solutions, a top holding plate 14 is installed in the inner cavity of the connecting plate 6 . The top holding plate 14 is arranged above the connecting block 74 , and the lower wall of the top holding plate 14 is in contact with the upper wall of the connecting block 74 .

[0035] In this technical solution, the supporting plate 14 can support the connecting block 74 , and the second clamping plate 72 can be prevented from tilting by pressing the connecting block 74 .

[0036] Working principle: The staff clamps the automobile connecting part 3 on the two clamping mechanisms 7 under the connecting plate 6, and then starts the sandblasting machine 2 to sandblast and polish the automobile connecting part 3. When the sandblasting machine 2 is started for sandblasting and polishing, the two clamping mechanisms 7 are opened alternately so that the automobile connecting part 3 does not fall off. The sandblasting machine 2 can sandblast and polish the part blocked by the first clamping plate 71 and the second clamping plate 72, thereby avoiding grinding dead corners and improving grinding efficiency.
