Technical Field
[0001] This utility model relates to the field of lathe base technology, specifically a lathe quick mold change base. Background Technology
[0002] Traditional lathe mold holders typically use multiple bolts to fix the workpiece, requiring each bolt to be removed during disassembly. When installing traditional workpieces, the inner diameter of the threaded hole is prone to deviation from the hole in the workpiece, resulting in misalignment and affecting machining accuracy. In addition, traditional bases are prone to vibration during machining and have poor chip removal, leading to reduced machining efficiency.

The auxiliary hole-aligning mechanism is used to improve the accuracy and efficiency of workpiece installation and disassembly. The auxiliary hole-aligning mechanism includes a hole ring with an inner diameter accuracy of 0.005 mm. The workpiece is installed by bolts engaging with the hole ring.
[0006] Furthermore: the mounting hole has a limiting groove on its side, a limiting block is fixed to the outside of the hole ring, the limiting block has a fixing hole, and the fixing hole fixes the hole ring to the support platform by bolts.
[0007] Furthermore, the lower end of the base is provided with a washer ring, and the washer ring has a corresponding hole, which is fixedly connected to the lathe. The washer ring reduces machining vibration.
[0008] Furthermore, the support platform is provided with chip removal grooves, which are interconnected and evenly divide the support platform into three equal parts.
[0009] Furthermore, the base has a central hole in the middle, which is used to improve the installation efficiency of the base with the lathe and the workpiece.
[0010] Furthermore, the edges of the chip removal groove are rounded.
[0011] This invention provides a quick mold change base for lathes. Compared with the prior art, it has the following advantages:
[0012] This lathe quick-change mold base improves workpiece installation and disassembly efficiency through an auxiliary hole-aligning mechanism.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a quick mold change base for a lathe; specifically, it includes a base 1, with a support platform 2 provided at the upper end of the base 1. The mold base of the lathe is used to fix the workpiece to be processed, and traditionally it is fixed by multiple bolts. When disassembling, multiple bolts need to be removed. The lathe mold base is a known technology and will not be described in detail here. An installation hole 4 is provided at the upper end of the support platform 2, and an auxiliary hole-aligning mechanism is provided in the installation hole 4. The auxiliary hole-aligning mechanism can quickly install the workpiece, and at the same time, the auxiliary hole-aligning mechanism can also quickly disassemble the workpiece during disassembly.
[0020] The auxiliary hole-aligning mechanism includes a hole ring 9, the inner diameter of which is ground to a precision of 0.005mm. During installation, the workpiece is inserted into the hole ring 9 via bolts, which improves the efficiency of workpiece positioning. The high-precision design improves the installation accuracy, thereby increasing the workpiece installation efficiency. At the same time, the workpiece will not shift during disassembly compared to traditional installation, and the bolts can still be easily removed during disassembly, thus improving the disassembly efficiency.
[0021] A limiting groove 5 is made on the side of the mounting hole 4, and a limiting block 10 is fixed on the outer end of the hole ring 9. A fixing hole 11 is made on the limiting block 10. The fixing hole 11 is used to fix the hole ring 9 and the limiting block 10 to the support platform 2 by bolts. The hole ring 9 and the limiting block 10 are fixed in this way, so that they can be replaced after a period of use, thereby maintaining a high precision effect.
[0022] A washer 7 is provided at the lower end of the base 1. The washer 7 has a corresponding hole 8. It is fixed by bolts. The corresponding hole 8 corresponds to the installation position at the lower end of the base 1, thus achieving a matching effect. It is fixed to the lathe through the corresponding hole 8 to reduce the vibration of the base 1 when processing the workpiece.
[0023] Chip removal grooves 6 are provided on the support platform 2. The chip removal grooves 6 are interconnected and divide the support platform 2 into three equal parts. This can improve chip removal efficiency when processing workpieces and prevent processing chips from accumulating on the base 1.
[0024] The base 1 has a central hole 3 in the middle, which can improve the installation efficiency between the base 1 and the lathe and the workpiece.
