[0042] Embodiment 3 of the utility model of a surface grinding device for fastener production

[0043] Reference Figure 1-Figure 5As shown, a pair of servo cylinders 2002 are inserted into the upper end surface of the support frame 2001, and the bottom ends of the servo cylinders 2002 are fixedly connected to the upper end of the dust box 2003. An opening is provided on one side of the protective cover 2004, and tempered glass is installed inside the opening. A collection port is provided on one side of the dust box 2003, and a closed door 2018 is hinged on one side of the collection port through a pair of hinges. The servo cylinder 2002 facilitates the uniform speed control of the dust box 2003 to press down, so that the grinder 2009 contacts the surface of the fastener, thereby grinding the fastener. The tempered glass makes it convenient for the user to observe the internal processing status of the protective cover 2004, and by installing the closed door 2018, it is convenient for the user to centrally clean the waste chips inside the dust box 2003.

[0044] Specifically, the working principle of the surface grinding device for fastener production is as follows: when in use, the fastener to be processed is placed inside the pneumatic clamp 1003 for fixing, and then the servo cylinder 2002 is started to drive the dust box 2003 to press down, and the protective cover 2004 is installed by sliding inside the annular groove 2012, so that when the dust box 2003 descends, the protective cover 2004 first contacts the upper end surface of the box body 1001 and covers the fastener therein. As the servo cylinder 2002 drives the dust box 2003 to press down, the grinder 2009 contacts the surface of the fastener and then grinds it. While grinding, by starting the linear motor 1002, the grinder 2009 can be moved forward and backward, and by starting the servo motor 216, the screw rod 2013 can be driven to rotate, and then the slider 214 drives the grinder 2009 to move left and right, so as to grind the surface of the fastener clamped at different positions on the pneumatic clamp 1003.

[0045] The waste chips generated during the grinding process can be sucked into the dust box 2003 by starting the negative pressure fan 219, thereby generating a negative pressure area at the inlet of the dust pipe 2007, so that the waste chips generated by the grinder 2009 during grinding can be sucked into the dust box 2003 in time. The hinged closed door 218 is convenient for the user to clean the waste chips inside the dust box 2003 after opening it. The tension spring 2011 is installed so that when the dust box 2003 is lifted, the protection cover 2004 can be lifted by the tension spring 2011. And when the dust box 2003 is pressed down, the elastic force of the tension spring 2011 can also resist the protection cover 2004, so that it can better fit with the upper end surface of the box body 1001.

[0046] It should be noted that in a surface grinding device for fastener production, the specific models and specifications of the servo motor 2013, grinder 2009, servo cylinder 2002 and negative pressure fan 2019 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
