Description
Technical Field
The utility model belongs to the technical field of refractory material product processing technique and specifically relates to a lathe plug for product location and specifically relates to a special-shaped fixed technique in the refractory material product bottom that needs turning.
Background
For some refractory products (fig. 1) with the shape to be processed and the bottom end angled, the refractory product is difficult to fix and unable to position when being installed on a numerical control lathe, and the lathe core rod is needed for processing. However, when the existing lathe core rod is used for fixing the refractory material product, all surfaces in the refractory material product are difficult to fix, so that micro shaking occurs when the refractory material product is subjected to shape processing, and defective products are increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problem that prior art exists, provide a lathe plug for product location, this lathe plug is applicable to the bottom angle and is greater than 0, is less than the fixed of 90 all refractory material products.
The utility model aims at solving through the following technical scheme:
a lathe mandrel for product positioning, comprising a mandrel rod, characterized in that: the bottom end of the mandrel rod is provided with a positioning block, and the positioning surface of the positioning block is matched and complemented with the surface to be fixed of the refractory material product to be fixed.
The angle of the positioning surface of the positioning block is 0-90 degrees.
The top end of the mandrel rod is provided with a fixing plate, and the lathe mandrel is fixed on a lathe through the fixing plate.
The mandrel rod is provided with a supporting block, the outer diameter of the supporting block is the same as the inner diameter of the inner cavity of the refractory material product to be fixed, so that the mandrel rod can be embedded in the inner cavity of the refractory material product to be fixed.
The core rod is provided with a plurality of supporting blocks, the upper parts of the supporting blocks are cylinders, and the lower parts of the supporting blocks are frustum tables, so that the core rod can be conveniently inserted into the inner cavity of a refractory material product to be fixed.
Compared with the prior art, the utility model has the following advantages:
the utility model discloses a lathe plug is applicable to the bottom angle and is greater than 0 °, is less than the fixed of 90 all refractory material products, can be to the fine fixed of refractory material product that will process and guarantee the eccentricity of refractory material product when adding man-hour.
Drawings
FIG. 1 is a schematic structural diagram of a refractory product to be fixed;
fig. 2 is a schematic structural view of the lathe mandrel for positioning a product according to the present invention.
Wherein: 1-mandrel bar; 2, positioning blocks; 3, fixing a plate; 4-supporting block.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 2: a lathe mandrel for positioning a product comprises a mandrel rod 1, wherein a positioning block 2 is arranged at the bottom end of the mandrel rod 1, and a positioning surface of the positioning block 2 is matched and complemented with a surface to be fixed of a refractory material product to be fixed; the angle of the positioning surface of the positioning block 2 is 0-90 degrees.
In addition to the above configuration, the fixed plate 3 is provided at the tip of the mandrel bar 1, and the lathe mandrel is fixed to the lathe via the fixed plate 3. The mandrel rod 1 is provided with a supporting block 4, the outer diameter of the supporting block 4 is the same as the inner diameter of the inner cavity of the refractory material product to be fixed, so that the mandrel rod 1 can be embedded in the inner cavity of the refractory material product to be fixed; the mandrel rod 1 is provided with a plurality of supporting blocks 4, the upper parts of the supporting blocks 4 are cylinders, and the lower parts of the supporting blocks 4 are frustum, so that the mandrel rod 1 can be conveniently inserted into the inner cavity of a refractory material product to be fixed.
When the lathe mandrel is used, the lathe mandrel is firstly processed through the fixing plate and fixed on a lathe, a refractory material product is sleeved into the lathe mandrel, the bottom end of the refractory material product is attached to the positioning block 2, and the angle of the positioning surface of the positioning block 2 is specially changed according to the bottom end angle of the refractory material product; then adopt support piece to withstand the bottom of refractory material product, then fix a position the refractory material product, can not produce at the turning appearance in-process and rock, guarantee the eccentricity of refractory material product when processing.
The above embodiments are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical scheme according to the technical idea provided by the present invention all fall within the protection scope of the present invention; the technology not related to the utility model can be realized by the prior art.
