Description

Technical Field

[0001] This utility model relates to the field of vertical lathe technology, and in particular to a machine tooling for machining the base of a vertical lathe. Background Technology

[0002] In industries such as motor manufacturing and heavy machinery, the machine base is one of the core components, and its machining accuracy directly affects the performance of the entire machine. Machine base machining is typically performed on a vertical lathe. In traditional processes, the base blank's base plane is usually used as the positioning reference. First, a jig is drilled, and then the machine is clamped using a clamping plate and chuck for alignment. This clamping method has several drawbacks: First, using the unmachined blank surface as a reference results in poor positioning accuracy, making it difficult to ensure the consistency of machining dimensions for critical parts such as the machine base's stops and internal cavities; second, the clamping process is cumbersome, relies heavily on the operator's experience, and is inefficient; finally, the traditional clamping plate method lacks rigidity, easily causing vibration or slight displacement under large cutting forces, affecting machining quality, and the fixed clamping plate position has poor versatility, making it difficult to adapt to machine bases of different sizes. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a machining fixture for the base of a vertical lathe.

[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a machine base machining fixture for a vertical lathe, including a fixture body and a pressure plate. The fixture body is installed on the vertical lathe chuck. The upper surface of the fixture body is provided with a plurality of pressure plate mounting grooves. The bottom of the fixture body is provided with a bottom threaded connection part corresponding to the pressure plate mounting grooves. The pressure plate includes a pressing part and a connecting part. The connecting part is disposed in the pressure plate mounting groove, and its lower end extends to the bottom of the tooling body. It is locked to the bottom threaded connection part of the tooling body by locking bolts.

[0005] Preferably, the clamping part is connected to the connecting part by a pin.

[0006] Preferably, the tooling body is provided with a chip removal groove.

[0007] Preferably, the chip removal groove is a through groove extending from the central area of ​​the tooling body toward its outer edge.

[0008] Preferably, the number of pressure plate mounting slots is four, and they are symmetrically distributed on the tooling body.

[0009] Preferably, the pressure plate is an inner pressure plate that acts on the inner side of the center hole of the machine base.

[0010] Compared with the traditional structure, the beneficial effects of this utility model are: This invention uses the precision-machined upper surface of the tooling body as a unified positioning reference, completely eliminating the original blank reference and ensuring the consistency of the machine base installation dimensions and machining accuracy.

[0011] The connecting part of the pressure plate extends to the bottom of the tooling body and is tightened by locking bolts, forming a very strong "pull-down" locking structure, which greatly enhances the rigidity of the clamping system, effectively resists cutting forces, and prevents vibration and displacement.

[0012] The clamping part and the connecting part of the pressure plate are connected by a pin, which allows the clamping part to be infinitely adjustable in the radial direction. One set of tooling can meet the clamping requirements of various machine bases of different specifications and sizes, and has excellent versatility.

[0013] The directional chip removal grooves on the main body of the tooling can guide the chips generated during the machining process to smoothly and quickly leave the machining area, avoiding chip accumulation that could affect the workpiece surface, the cutting tool, and the machining accuracy.

The fixture body 2 is mounted on a vertical lathe chuck 1. The upper surface of the fixture body 2 is provided with a plurality of pressure plate mounting grooves 7. The bottom of the fixture body 2 is provided with a bottom threaded connection part corresponding to the pressure plate mounting grooves 7. The pressure plate 4 includes a pressing part 41 and a connecting part 42. The connecting part 42 is disposed in the pressure plate mounting groove 7, and its lower end extends to the bottom of the tooling body 2. It is locked to the bottom threaded connection part of the tooling body 2 by locking bolts 6.

[0017] In this preferred embodiment, the pressing part 41 is connected to the connecting part 42 via a pin 8.

[0020] In this preferred embodiment, there are four pressure plate mounting slots 7, which are symmetrically distributed on the tooling body 2.

[0021] In this preferred embodiment, the pressure plate 4 is an inner pressure plate that acts on the inner side of the center hole of the base 5.

[0022] In this preferred embodiment, the cross-section of the pressure plate mounting groove 7 is rectangular, and its width matches the width of the connecting part 42 of the pressure plate 4, forming a sliding fit.

[0023] In practice, firstly, the main fixture 2 is installed and aligned on the vertical lathe chuck 1; then, the machine base 5 is hoisted onto the precision-machined positioning surface of the main fixture 2; according to the dimensions of the machine base 5, the clamping parts 41 of each pressure plate 4 are radially adjusted to the appropriate position; the connecting parts 42 of the pressure plates 4 are placed into the pressure plate mounting groove 7, so that the clamping parts 41 press against the corresponding parts of the machine base 5; finally, each pressure plate 4 is tightly locked from the bottom of the main fixture 2 with locking bolts 6. After completion, high-precision machining of the machine base 5 can begin, using the upper surface of the main fixture 2 as a reference.
