DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present application discloses a CNC machining center guide rail auxiliary fixture, referring to Figure 1 , Figure 2 and Figure 3 , including a machining center body 1, wherein a machining room is provided inside the machining center body 1, an operation port is provided on the front of the machining center body 1, the operation port is connected to the machining room, and a mounting platform 11 is provided in the machining room of the machining center body 1, on which a tooling seat 13 is mounted, so as to clamp the workpiece. A first sliding frame 2 is horizontally slidably mounted along the width of the operation port on the front of the machining center, and the first sliding frame 2 should be lower than the height of the mounting platform 11. A second sliding frame 3 is also slidably mounted on the top of the first sliding frame 2, and the second sliding frame 3 slides along the depth direction of the operation port, and a transfer seat 4 is movably provided on the second sliding frame, and the transfer seat 4 is used to pre-install the tooling seat 13.

[0022] Reference Figure 4 and Figure 5 The transfer seat 4 is provided with a fixing assembly for fixing the tooling seat 13. Specifically, the fixing assembly includes a positioning angle block 6. The positioning angle block 6 is in a right-angled L-shape. The two sides of the positioning angle block 6 can be installed in contact with the side panels of the installation platform 11 and the tooling seat 13. The transfer seat 4 is provided with a plurality of first screw holes 61 in an array. The side panels of the tooling seat 13 are provided with screw holes. The first bolts 62 are passed through the positioning angle blocks 6 and then threadedly connected with the screw holes on the tooling seat 13 and the first screw holes 61 on the installation platform 11. By providing the positioning angle blocks 6 on both sides of the tooling seat 13, the tooling seat 13 can be fixed on the transfer seat 4. The plurality of first screw holes 61 in an array on the transfer seat 4 can enable the positioning angle blocks 6 to be adapted to tooling seats 13 of different sizes for installation.

[0023] The installation platform 11 is provided with a guide assembly for positioning and guiding the transfer seat 4. In the embodiment of the present application, the guide assembly includes a support seat 52 arranged at the four corners of the transfer seat 4, a ball seat 53 is vertically slidably installed at the bottom of the support seat 52, a support ball 51 is rollingly installed at the bottom of the ball seat 53, and a first elastic member 54 is provided inside the support seat 52, which is used to drive the ball seat 53 to move downward in the support seat 52 and make the support ball 51 protrude from the bottom end of the support seat 52. The first elastic member 54 is specifically a spring, one end of the spring abuts against the inner bottom wall of the support seat 52 inside the support seat 52, and the other end abuts against the ball seat 53. When the transfer seat 4 moves, the support ball 51 is pushed by the spring to support and lift the tooling seat 13, so that the transfer seat 4 can move smoothly on the second sliding frame 3 and the installation platform 11.

[0024] The rolling grooves provided on the second sliding frame 3 and the mounting platform 11 can guide the movement of the transfer seat 4. Furthermore, the two rows of support balls 51 on the transfer seat 4 along the moving direction of the transfer seat 4 are mutually offset, so that there are four rail grooves 55 on the mounting platform 11 and the second sliding frame 3, and each support ball 51 slides in a corresponding rail groove 55. Positioning grooves 56 corresponding to the support balls 51 are provided at the ends of the rail grooves 55 on the mounting platform 11. When the transfer seat 4 moves onto the mounting platform 11, the support balls 51 can move into each positioning groove 56 to position the transfer seat 4. The rail grooves 55 are independent of each other, which can also prevent the transfer seat 4 from bumping during movement.

[0025] By setting the first sliding frame 2, the second sliding frame 3 and the transfer seat 4, the staff can hoist the tooling seat 13 on the transfer seat 4 outside the processing room of the processing center body 1, and then move the first sliding frame 2, align the operation port on the processing center body 1, and push the second sliding frame 3 into the processing room, so that the top of the second sliding frame 3 is flush with the installation top wall, the second sliding frame 3 is in contact with the rail groove 55 on the installation platform 11, and then move the transfer frame to the installation platform 11 for positioning, and the installation of the tooling seat 13 can be completed. There is no need to install the tooling seat 13 by hanging it from top to bottom, which improves the safety of the installation process of the tooling seat 13.

[0026] Furthermore, a positioning rod 31 is fixedly provided on one side of the second sliding frame 3 close to the mounting platform 11, and a positioning seat 12 adapted to the positioning rod 31 is provided on one side of the mounting platform 11 close to the second sliding frame 3. A connecting groove 121 adapted to the positioning rod 31 is provided on the positioning seat 12, and a first magnetic member for magnetically adsorbing the positioning rod 31 is provided on the inner bottom wall of the connecting groove 121. The first magnetic member is a magnet, and when the second sliding frame 3 moves to contact the mounting platform 11, the positioning rod 31 and the connecting groove 121 are plugged into each other, which plays an auxiliary supporting role for the suspended part of the second sliding frame 3, improves the stability of the second sliding frame 3, and the second sliding frame 3 is magnetically adsorbed by the first magnetic member, which can play a simple fixing role for the second sliding frame 3.

[0027] Furthermore, a plurality of positioning blocks 7 are fixedly arranged on the installation platform 11, and a second screw hole is vertically provided on the positioning block 7. A through hole corresponding to the second screw hole on the positioning block 7 is provided on the transfer seat 4, and the transfer seat 4 is threadedly connected with the second screw hole on the installation platform 11 through a second bolt 71. In the embodiment of the present application, there are three positioning blocks 7. After the support balls 51 on the transfer seat 4 are embedded in the positioning grooves 56 on the installation platform 11 one by one, the through holes on the transfer seat 4 correspond to the second screw holes on the installation platform 11 one by one, and then the second bolt 71 is passed through the through hole on the transfer seat 4 and then threadedly connected to the second screw hole on the positioning block 7, the transfer seat 4 can be further fixed, and the stability of the tooling seat 13 during use can be improved.
