DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution 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.

[0028] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] like Figure 3 to Figure 6 As shown, a tool for boring a tailstock body comprises a support pad 3 for fixing the tailstock body, connecting flange edges 4 are respectively provided on both sides of the support pad 3, and a plurality of connecting grooves 5 are respectively provided on the connecting flange edges 4, and the connecting grooves 5 are used to connect T-bolts to connect with the T-slots on the machine tool worktable; the other side edge of the support pad 3 is also detachably connected with a plurality of side limit blocks 6, and a clearance space is also provided between the side limit blocks 6 and the side faces of the support pad 3, and the clearance space is used to accommodate the bottom flange 2 of the tailstock body 1, and the side limit blocks 6 are also provided with a tightening screw 8 at the clearance space, and the tightening screw 8 is used to lock the bottom flange 2.

[0030] The tooling for boring a tailstock body has a simple structure, is easy to manufacture and install, and has strong practicality. It can well fix the tailstock body 1 to be processed, and ensure that the tailstock body 1 is stably and reliably installed on the workbench of a machine tool, so that the CNC machine tool can perform boring processing on the tailstock body. At the same time, it can well ensure the side position of the tailstock body and the position of the hole to be processed, which is beneficial to improving the accuracy and dimensional accuracy of the boring.

[0031] The support pad 3 is provided, on the one hand, to support the tailstock body 1 so that the bottom flange 2 of the lower edge of the tailstock body 1 can be against the side of the support pad 3, which can ensure that the tailstock plate is horizontal and avoid interference between the bottom flange 2 and the machine tool worktable; on the other hand, it can use the connecting flange edges 4 on both sides to fix itself, and the connecting grooves 5 on the connecting flange edges can be connected to the T-bolts, which can be connected to the T-slots of the machine tool worktable and can be moved. After adjusting the position, it can be locked to fix the support pad.

[0032] The side limit block 6 cooperates with the setting of the tightening screw 8 to clamp the bottom flange 2, that is, to clamp the tailstock body 1 to be processed, fix it on the support pad 3, and limit its side. This connection method will not cause motion interference and conflict with the machine tool worktable, can more conveniently tighten the tailstock body, and is also relatively simple to operate.

[0033] The side limit block 6 is configured to be detachable so that it can be removed, especially when parts such as the tailstock body are not being processed. In this way, the support pad 3 can also serve as a support platform to support and fix other types of parts, thereby improving the utilization rate of the tooling and avoiding its idleness.

[0034] Furthermore, an oblique through hole 9 is provided in the middle area of ​​the support pad 3 , and an internal thread is provided in the through hole 9 .

[0035] In order to further improve the connection and installation stability and positioning accuracy of the tailstock body 1, the through hole 9 is provided on the support pad 3. Since there are also some inclined holes 10 on the tailstock body 1, the tailstock body 1 can be further connected and fixed by long bolts or long screws 11 passing through the inclined holes 10 and connected to the through holes 9. Moreover, due to the inclination, this connection enables it to have force components in both the horizontal and vertical directions, and the fixing effect is better. The upper end of the long bolt or screw can be locked by a gasket and a nut, and it will not cause damage to the tailstock body.

[0036] Furthermore, the side limit block 6 includes a horizontal portion 601 and a vertical portion 602 arranged at the edge of the horizontal portion 601 . The horizontal portion 601 abuts against the side of the support pad 3 and is connected via a plurality of fastening screws 7 .

[0037] By setting up this structure, the side limit block 6 can be connected and fixed more conveniently, and the clearance space can be formed between the vertical part 602 and the supporting pad 3 to accommodate the bottom flange 2 of the tailstock body; and this structure can accommodate bottom flanges of various thickness sizes.

[0038] Furthermore, the fastening screws 7 are a pair, and the pair of fastening screws 7 and the top tightening screws 8 are arranged in a herringbone shape, and the center lines of the three screws are exactly at the three vertices of the regular triangle.

[0039] In some embodiments, the fastening screw 7 is installed in a countersunk manner, so that the end of the fastening screw 7 can be immersed in the horizontal part 601, leaving external space for using a tool to tighten the top screw 8. For example, when using a wrench to tighten the top screw, there will be no screws on both sides to affect the rotation of the wrench.

[0040] Furthermore, the side limit blocks 6 are integrated iron blocks or steel blocks with high structural strength, and 2 to 4 side limit blocks 6 are arranged at intervals.

[0041] Furthermore, the support pad 3 is a hollow metal structure with a plurality of windows 12 on the top, and such a configuration can reduce the weight of the support pad 3, facilitate its movement or transportation, and also reduce its manufacturing material. Moreover, such a configuration is conducive to the heat dissipation of the tailstock body and the downward flow of the coolant.

[0042] Furthermore, the upper edge of the support pad 3 near the side limit block 6 is set as a chamfer structure 15. The setting of the chamfer structure 15 can prevent the sharp corners from scratching the tailstock body 1, and also consider that the right angle at the convex edge of the bottom of the tailstock body may be uneven, thereby reducing the mutual influence between the right angles. The chamfer structure can be an oblique chamfer or a rounded chamfer.

[0043] Furthermore, the bottom surface of the connecting flange edge 4 is flush with the bottom surface of the support pad 3, ensuring that the support surface of the entire bottom is on the same horizontal plane, which is conducive to stable support on the workbench; after the side limit block is fixed on the support pad, a gap is provided between the bottom of the side limit block 6 and the bottom surface of the support pad 3, so as to prevent the side limit block 6 from touching the workbench and causing interference.

[0044] Furthermore, the connecting groove 5 is a U-shaped open groove, which is convenient for connecting the T-bolt, and there are three connecting grooves 5.

[0045] A method of using the tooling for boring a tailstock body is as follows: placing the support pad 3 on the workbench of a machine tool, connecting T-bolts at the connecting groove and the T-slot, wherein the T-bolts are pre-connected and not locked at this time; placing the tailstock body 1 to be processed on the support pad 3, adjusting the position of the tailstock body 1 so that the through hole 9 corresponds obliquely to the inclined hole 10 on the tailstock body, and connecting the long screw 11; connecting and fixing the side limit block 6 to the side of the support pad 3, or connecting and fixing the side limit block 6 to the side of the support pad 3 in advance, and then tightening the tightening screw 8, so that the tightening screw 8 clamps the tailstock body 1 from the side, and the long screw 11 is also locked; fine-tuning the position of the support pad 3 according to the processing position to meet the requirements, and finally tightening the T-bolt.

[0046] In other embodiments, Figure 7 As shown, the side of the support pad 3 is further provided with a positioning protrusion 13, and the side limit block 6 is provided with a magnetic hole 14 that matches the positioning protrusion 13. A magnet is embedded in the magnetic hole 14.

[0047] The positioning protrusion 13 and the magnetic hole 14 cooperate to facilitate the positioning of the side limit block 6; when the side limit block 6 is not yet connected to the fastening screw 7, it can play a pre-connection role, and it will not fall off or move by itself, which is convenient for the subsequent connection of the fastening screw. When disassembling, when the fastening screw 7 is screwed out, the side limit block 6 will not fall directly due to magnetic attraction, which can prevent it from accidentally falling and injuring the workbench or the operator.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
