Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and in particular to a combined tool post for a horizontal milling machine. Background Technology

[0002] A horizontal milling machine is a machine tool whose spindle is parallel to the worktable and in a horizontal position. It operates at 12 speeds and can use various cylindrical end mills, disc end mills, angle end mills, form end mills, and face end mills to machine various planes, inclined surfaces, grooves, etc. It can be divided into universal horizontal milling machines, horizontal lifting table milling machines, and universal rotary head milling machines, etc.

[0003] When machining a workpiece using a horizontal milling machine, a tool post is typically installed on the machine, on which multiple milling cutters are arranged. Each cutter is driven by a drive mechanism to rotate. The clamping device on the milling machine feeds the workpiece and performs the machining. A roughing cutter is mounted on the tool post. To better complete the roughing process, the roughing cutter needs to be moved. However, existing structures suffer from several drawbacks: an unreasonable layout design results in a less compact overall structure; secondly, the use of ordinary guide rails for guidance leads to unreliable guidance that does not meet accuracy requirements, and it is inconvenient to adjust the guidance accuracy.

[0004] Therefore, how to provide a combination tool post for horizontal milling machines with a simpler and more compact structural design, a more reasonable guiding design, and easier adjustment of guiding accuracy has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to provide a combination tool post for a horizontal milling machine with a simpler and more compact structural design, a more reasonable guiding design, and more convenient adjustment of guiding accuracy.

[0006] To achieve the above objectives, this utility model provides a combined tool post for a horizontal milling machine, comprising a first support plate, a first mounting plate above the first support plate, and a transverse movement control mechanism between the first mounting plate and the first support plate; a vertical second support plate is connected and fixed to one end of the first mounting plate, a second mounting plate is provided on the outer side of the second support plate, and a longitudinal movement control mechanism is provided between the second mounting plate and the second support plate; a roughing milling tool mechanism is provided on the outer side of the second mounting plate; characterized in that; the transverse movement control mechanism includes a first dovetail guide rail and a first slider that cooperates with the first dovetail guide rail, wherein the first slider has a guide groove. A first adjusting strip is provided on the side, and a number of screw holes are provided on the side of the first slider, with a first adjusting screw in cooperation, so that the first adjusting screw can abut against the first adjusting strip and push the first adjusting strip to adhere to the side of the first dovetail guide rail; the longitudinal movement drive control mechanism includes a second dovetail guide rail and a second slider that cooperates on the second dovetail guide rail, and a second adjusting strip is provided inside the guide groove of the second slider, and a number of screw holes are provided on the side of the second slider, with a second adjusting screw in cooperation, so that the second adjusting screw can abut against the second adjusting strip and push the second adjusting strip to adhere to the side of the second dovetail guide rail.
