[0026] The utility model aims to provide a slider through-hole processing fixture for a lateral core pulling mechanism, which has accurate positioning and stable clamping, and solves the problem of low processing precision of the slider oblique guide post hole.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 5As shown, this embodiment provides a slider through-hole processing fixture for a lateral core pulling mechanism, including: a clamp body 1 and a fastening structure, the clamp body 1 is provided with a mounting groove and a chip groove 6, the mounting groove is used to place the slider 3, the chip groove 6 is used to accommodate the chips formed by the slider 3 processing the through hole, the fastening structure is connected to the clamp body 1, and the fastening structure is used to fix the slider 3 in the mounting groove.

[0029] Specifically, in this embodiment, the mounting groove includes a right-angle positioning surface 7, a plane positioning surface 5, a front end surface and a rear end surface. The front end surface is the end surface close to the tool block 4, and the front end surface and the rear end surface are arranged opposite to each other. The right-angle positioning surface 7 is respectively perpendicular to the plane positioning surface 5 and the front end surface, and the plane positioning surface 5 is perpendicular to the front end surface. The right-angle positioning surface 7 is connected to the plane positioning surface 5. The front end of the right-angle positioning surface 7 and the front end of the plane positioning surface 5 are both connected to the front end surface, and the rear end of the right-angle positioning surface 7 and the rear end of the plane positioning surface 5 are both connected to the rear end surface. The right-angle positioning surface 7 is used to position the side of the slider 3, the plane positioning surface 5 is used to position the bottom surface of the slider 3, and the front end surface is used to position the front end surface of the slider 3. The fastening structure is screwed into the rear end surface of the mounting groove and contacts the rear end surface of the slider 3.

[0030] In this embodiment, the fastening structure includes two bolts 2, the number of bolts 2 is set according to actual needs, the axis of the bolt 2 is set parallel to the planar positioning surface 5 of the installation groove, the bolt 2 is threadedly connected to the clamp body 1, and one end of the bolt 2 is used to contact the slider 3.

[0031] In this embodiment, two mounting grooves are provided on the clamp body 1. The number of mounting grooves can be set according to actual needs. The mounting grooves are inclined. A tool setting block 4 is provided between the two mounting grooves. The upper surface of the tool setting block 4 is horizontally arranged. The tool setting block 4 is detachably connected to the clamp body 1. The two mounting grooves are symmetrically arranged about the tool setting block 4. Two blanks can be installed each time when processing the through hole (oblique guide column hole) of the slider 3, which improves production efficiency and realizes multi-station processing. The tool setting position of the slider 3 is solved by setting the tool setting block 4. When programming the processing, the processing coordinate system is set at the center position of the upper surface of the tool setting block 4, so as to keep it consistent with the actual processing.

[0032] In this embodiment, the chip groove 6 is located below the mounting groove, the chip groove 6 is communicated with the mounting groove, the position of the chip groove 6 corresponds to the position of the through hole of the slider 3, and the width of the chip groove 6 is greater than the diameter of the through hole.

[0033] In this embodiment, Figure 5 As shown, the total height of the clamp body 1 is: the sum of the clamping height H of the flat-nose pliers during processing and the height for easy observation during processing of the processed slider 3 and to prevent the tool handle from colliding with the flat-nose pliers.

[0034] When using this embodiment, before processing the slider 3, four bolts 2 are first inserted into the mounting groove from the rear end face of the mounting groove, and then the slider 3 is placed on the plane positioning surface 5, and the bottom surface of the slider 3 is in contact with the plane positioning surface 5, and the side surface of the slider 3 is in contact with the right-angle positioning surface 7.

After the positioning is confirmed, the four bolts 2 are tightened and screwed until the end faces of the bolts 2 are in close contact with the slider 3, and the slider 3 is tried to be moved to confirm that the clamping is correct.

[0035] During processing, in order to completely drill through the through hole (oblique guide post hole) of the slider 3 and to prevent the clamp body 1 from overcutting, a chip groove 6 is provided in the clamp body 1. When the tool processes the through hole (oblique guide post hole) of the slider 3, there is enough moving distance in the depth direction, which effectively solves the problem of overcutting the clamp body 1. At the same time, the chip groove 6 can provide space for the metal chips generated during processing to ensure stability during processing.

[0036] After processing, first loosen the four bolts 2. During this process, keep the slider 3 on the clamp body 1. At this time, the bolts 2 are not completely unscrewed from the clamp body 1 to prevent the bolts 2 from being lost. Finally, take the slider 3 out of the clamp body 1 for the next reinstallation and processing.

[0037] The slider through-hole processing fixture for the lateral core pulling mechanism of this embodiment ensures the processing accuracy and stability of the through-hole (oblique guide column hole) size of the slider 3, reduces the requirements on the workers' technical level, reduces the workers' labor intensity, and shortens the processing auxiliary time.
