[0016] The utility model is further illustrated below in combination with the drawings and the preferred examples.
[0017] Example 1
[0018] Referring to Figures 1 to 4 The hinge front polishing tool relates to the utility model, and through the use of the positioning pin with the counterbore, the positioning pin is inserted into the counterbore on the front of the hinge plate and the positioning hole on the positioning platform, and the counterbore is embedded into the counterbore on the front of the hinge plate; the locking block which moves horizontally is used to realize the axial locking of the positioning pin, so that the hinge plate is clamped and positioned on the positioning platform, and the front is exposed outside, thereby facilitating polishing, the speciality is strong, the overall function is perfect, and the practicality is strong.
[0019] Further, the bottom of the positioning platform 1 is provided with a linear guide rail 12, and the locking block 4 is slidingly connected to the linear guide rail 12.
[0020] In the embodiment, in the initial state, the linear reciprocating mechanism 5 (i.e. the push rod cylinder) is in a shortened state, and the locking block 4 is away from the positioning hole 2. First, the hinge plate 100 to be polished on the front surface is taken, and the hinge plate 100 is placed on the positioning platform 1 with the front surface upward and the back surface downward, and the upper counterbore is aligned with the positioning hole 2. Then, the positioning pins 3 equal in number to the counterbores and matched with the positioning hole 2 are taken, and the positioning pins 3 are inserted into the corresponding counterbores and the positioning hole 2 in sequence until the counterbores 7 are completely buried. Then, the linear reciprocating mechanism 5 is operated to move the locking block 4 in the direction of approaching the positioning hole 2 until the locking slide 9 is inserted into the annular groove 8 along the tangential direction of the positioning pin to limit the axial movement of the positioning pin 3 relative to the positioning platform 1, thereby achieving the effect of locking the hinge plate placed on the positioning platform 1. Finally, the front surface of the hinge plate can be polished.
