Description

Technical Field

[0001] The invention belongs to the technical field of precision machining machine tools, and in particular relates to a ram glue pouring device and method for a numerically controlled machine tool. Background Art

[0002] Currently, there are two common methods for gluing the inner bore of a ram. One method involves gluing while the ram is lying flat. This method simplifies the gluing process and makes it easy to measure and guarantee the axial positioning accuracy of the gluing sleeve before gluing. However, measuring the coaxiality of the gluing sleeve with the spindle is more difficult, meaning radial positioning of the gluing sleeve is difficult. The other method involves gluing while the ram is upright. In this method, coaxiality between the gluing sleeve inner bore and the spindle mounting hole is easily guaranteed, but ensuring the axial position of the gluing sleeve is difficult. Summary of the Invention

[0003] In order to overcome the above technical problems, the purpose of the present invention is to provide a CNC machine tool slide glue pouring device and method, which is easy to operate, can effectively ensure the accuracy requirements of axial positioning and radial positioning of the glue pouring sleeve, and improve the slide transmission accuracy.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A ram glue pouring device for a numerically controlled machine tool comprises a glue pouring sleeve positioning fixture 3 and a ram 1. A spindle assembly 2, a glue pouring sleeve 1 4, a glue pouring sleeve 2 6, and a glue pouring sleeve 3 8 are placed inside the ram 1. The spindle assembly 2 is connected to a transmission assembly 9, which is mounted inside the glue pouring sleeve 1 4, the glue pouring sleeve 2 6, and the glue pouring sleeve 3 8. The glue pouring sleeve positioning fixture 3 is fixed to the ram 1 when in use.

[0006] The glue-filling sleeve positioning tool 3 includes a tool body 1 3-1, a tool body 2 3-2, a connecting plate, fastening screws, a sealing strip, and connecting screws. The tool body 1 3-1 and the tool body 2 3-2 are semi-circular ring structures, and the tool body 1 3-1 and the tool body 2 3-2 form a complete circular ring structure.

[0007] The tool body 1 3 - 1 and the tool body 2 3 - 2 are fixedly connected by connecting plates and connecting screws.

[0008] The tooling body 1 3 - 1 and the tooling body 2 3 - 2 are provided with step surfaces, and sealing strips are provided on the step surfaces.

[0009] The tooling body 1 3 - 1 and the tooling body 2 3 - 2 are provided with screw through holes arranged in an arc shape, and the fastening screws are used to fix the tooling body 1 3 - 1 and the tooling body 2 3 - 2 on the slide.

[0010] The glue-filling sleeve positioning tool 3 includes a tool body 1 3-1, a tool body 2 3-2 and a fastening screw. The tool body 1 3-1 and the tool body 2 3-2 are semicircular arc-shaped, and the tool body 1 3-1 and the tool body 2 3-2 are provided with screw through holes arranged in a circular arc shape. The fastening screw is used to fix the tool body 1 3-1 and the tool body 2 3-2 on the slide.

[0011] A method for using a ram glue pouring device for a CNC machine tool, comprising the following steps:

[0012] Make the ram 1 upright with the spindle mounting hole facing upwards, assemble the spindle assembly 2 and the ram 1 in the upright state, fix the tool body 1 3-1 and the tool body 2 3-2 on the ram with the glue sleeve positioning tool 3 with screws, and then fix the glue sleeve 1 4 axially to the tail of the spindle assembly 2. Rotate the spindle assembly 2 to automatically adjust the position of the glue sleeve 1 4 in the glue injection hole of the ram 1, and then start the glue injection once;

[0013] After the glue is cured, flip the ram 1 so that it is in a flat state, install the second glue sleeve 6, the third glue sleeve 8 and the transmission components 9, and fix the axial position of the second glue sleeve 6 and the third glue sleeve 8 with the glue sleeve positioning tool 3;

[0014] Flip the ram 1 again so that it is in an upright state, with the spindle assembly 2 facing downward, and rotate the transmission assembly 9 to automatically correct the positions of the second and third glue sleeves 6 and 8 in the glue injection inner hole of the ram. Glue is injected for the second time. After the glue is cured, remove the glue sleeve positioning tooling 3 and the glue injection is completed.

[0015] Beneficial effects of the present invention.

[0016] A semicircular arc-shaped glue potting positioning fixture is used to ensure the axial position accuracy of the glue potting sleeve. When the slide is in an upright state, the main shaft assembly is rotated to automatically align the radial positioning accuracy of the glue potting sleeve. The operation is simple and the assembly efficiency is improved. The glue potting is carried out in two steps, which effectively improves the glue potting accuracy, improves the slide transmission accuracy, and improves the product quality.
