Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool assembly, and in particular relates to an adjustable tooling for supporting a machine tool lead screw. Background Art

[0002] The assembly process of machine tools directly affects the machining accuracy of machine tools. In order to improve the machining accuracy of machine tools, it is necessary to improve the machining processability and assembly processability. Assembly processability includes complete assembly process regulations, qualified machine tool design structure and reasonable assembly tooling. In the process of machine tool assembly, workers need to use a variety of tooling and fixtures to meet the assembly conditions. As the transmission component of the machine tool, the screw, the assembly tooling used is the top priority.

[0003] There are two common ways to assemble the lead screw. One is to use wooden blocks, iron pads and other objects to support the bottom of the lead screw. During the assembly of the lead screw and the bearing seat, the lead screw is lifted and installed by manpower or a crane. The other is to directly place the lead screw in the bearing hole, or place it on the machine tool parts, and it is also lifted and installed by manpower or a crane during installation. There are three important problems with the above two assembly methods: First, the lead screw will rub against the machine tool parts, causing damage to the lead screw, bearing hole or paint surface; second, the coaxiality of the lead screw and the bearing hole cannot be guaranteed. When the lead screw, bearing and bearing seat are installed together, the installation angle of the three will be incorrect, affecting the accuracy of the lead screw and bearing; third, because the coaxiality cannot be guaranteed, additional labor costs are required during assembly, such as rework caused by unqualified assembly, and staff manually lifting the lead screw to align the lead screw with the bearing hole.

[0004] Most of the existing screw support tooling are simple fixed structures. Once the machine tool structure is changed, the tooling may need to be remade, and the versatility of the tooling is poor. Therefore, there is an urgent need to develop an adjustable tooling for supporting machine tool screws that is highly versatile and labor-saving, so as to reduce unnecessary waste of manpower and improve the accuracy of screw assembly. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an adjustable tooling for supporting a machine tool lead screw.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] An adjustable tooling for supporting a machine tool lead screw comprises a base assembly, a horizontally slidable mounting frame is mounted above the base assembly, a vertically slidable support frame is mounted above the mounting frame, and an adjustment assembly is mounted between the support frame and the mounting frame; the mounting frame comprises a bottom plate, a countersunk hole is provided at the center of the bottom plate, and two guide grooves are provided opposite to each other on both sides of the top end of the bottom plate.

[0008] Furthermore, the base assembly includes a base body, the base body is provided with two oppositely arranged slide grooves, a slide rail is slidably connected in the slide groove, and the directions of the slide groove and the slide rail are perpendicular to the axial direction of the lead screw.

[0009] Furthermore, side plates are provided at both ends of the slide groove, and the side plates are fixedly connected to the base body; the side plates can prevent the slide rail from sliding out of the slide groove.

[0010] Furthermore, the bottom end of the base plate is fixedly connected to the top end of the slide rail.

[0011] Furthermore, the support frame includes a slide plate, which is located between the two guide grooves, and the two sides of the slide plate are slidably connected to the guide grooves. A threaded hole is opened at the center of the bottom end of the slide plate, and a V-shaped groove is opened at the top of the slide plate. A V-shaped plate is fixedly connected to the V-shaped groove. The setting of the V-shaped plate can increase the contact area with the screw, thereby providing a more stable support effect.

[0012] Furthermore, the V-shaped plate is made of nylon or acrylic material; nylon and acrylic materials can provide good protection for the surface of the lead screw.

[0013] Furthermore, the adjustment assembly includes an adjustment screw, the bottom end of the adjustment screw cooperates with the countersunk hole, the top end of the adjustment screw is threadedly connected to the threaded hole, and a knob is fixedly connected to the adjustment screw, and the knob is located between the slide plate and the bottom plate.

[0014] Beneficial effects:

[0015] The adjustable tooling of the utility model has a simple structure and is flexible and convenient to use. By rotating the knob on the adjustment screw and the position of the sliding mounting frame, the height and lateral position of the lead screw can be adjusted according to the actual installation position of the lead screw, which not only greatly reduces the labor cost, but also can very conveniently adjust the lead screw and the bearing hole of the bearing seat to be coaxial, thereby improving the assembly accuracy; in addition, through the setting of the V-shaped plate, the adjustable tooling of the utility model can be suitable for lead screws of different diameters, thereby improving the versatility of the tooling, and the V-shaped plate made of nylon or acrylic will not cause damage to the lead screw.
