Abstract
The invention discloses a work fixture for installing a workpiece, which comprises a fixed seat (1) and a positioning table (2), wherein the positioning table (2) is fixed on the fixed seat (1), and the positioning table (2) is provided with a fixing device for fixing the workpiece (3). A workpiece is fixed on the invention, and parts which can not be processed or have poor processing precision on a common machine tool can be processed after the tool is set. The invention has the advantages that: the processing capacity of a common machine tool is expanded, and a through hole with a certain angle with the axis is processed on the hemispherical shell of the workpiece.
Description
Technical Field
The invention belongs to a tool clamp, and particularly relates to a tool clamp for mounting a workpiece.
Background
A work fixture is a device for fastening a workpiece to hold a machine tool, a tool, and the workpiece in a relative position during product processing, and a special work fixture may have to be designed for a product in order to process a qualified product.
A through hole with a certain angle relative to the axis is required to be drilled on a hemispherical shell of a certain part, and for the part, the machining can be completed on a 6-axis machine tool, but the 6-axis machine tool is expensive, and many enterprises only have 4-axis machine tools of common machine tools, and the 4-axis machine tool of the common machine tool can only realize the movement in three directions and the rotation of one axis, so that the part cannot be machined. Therefore, a tool capable of reducing the processing difficulty of the part is needed to be designed so as to process the part on a common machine tool.
Disclosure of Invention
Aiming at the limitation of the existing common machine tool, the technical problem to be solved by the invention is to provide a tool clamp for mounting a workpiece, which can expand the processing capacity of the common machine tool and realize the processing of a through hole with a certain angle with an axis on the hemispherical shell of the workpiece.
The technical problem to be solved by the invention is realized by the technical scheme that the device comprises a fixed seat and a positioning table, wherein the positioning table is fixed on the fixed seat, and is provided with a fixing device for fixing a workpiece.
A workpiece is fixed on the invention, and parts which can not be processed or have poor processing precision on a common machine tool can be processed after the tool is set.
The invention has the technical effects that:
1. the invention reduces the requirements on processing equipment, can process parts which can be processed only by a 6-axis machine tool on a 4-axis machine tool, and can ensure certain processing precision.
2. The processing cost is saved, 6-axis machine tool equipment is expensive, the running cost is high, and if 4-axis machine tools are adopted to process the parts, the processing cost can be saved.
3. The processing period is shortened, and many enterprises have more 4-axis machine tools and less 6-axis machine tools. For a large batch of parts with inclined holes on the hemispherical shell, if the parts can be processed on a 4-axis machine tool, the processing period can be shortened.
Drawings
The drawings of the invention are illustrated as follows:
FIG. 1 is a top view of the invention;
fig. 2 is a sectional view taken along line a-a in fig. 1.
In the figure, 1, a fixed seat; 11. positioning pins; 12. a central positioning hole; 13. a threaded hole; 14. a machine tool clamping portion; 2. a positioning table; 21. positioning the boss; 22. a fixing device; 3. and (5) a workpiece.
Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
for the sake of clarity of the description of the invention, the present patent application uses the terms "upper" and "lower" which are determined according to the layout orientation of the above drawings, and the orientation of the invention in the practical use is changed, and the name of the orientation is changed, and it is not considered to limit the scope of the patent protection.
As shown in fig. 1 and 2, the present invention includes a fixing base 1 and a positioning table 2, wherein the positioning table 2 is fixed on the fixing base 1, and the positioning table 2 is provided with a fixing device for fixing a workpiece 3.
The fixing seat 1 is provided with a positioning pin 11 for processing and positioning and a threaded hole 13 fixedly connected with the positioning table 2, the center of the fixing seat is provided with a center positioning hole 12, and the fixing seat is provided with a machine tool clamping part 14.
The positioning table 2 is provided with a threaded hole and a positioning pin hole corresponding to the fixed seat, a positioning boss 21 corresponding to a central positioning hole is arranged below the center of the positioning table, and a fixing device 22 for fixing a workpiece is arranged above the positioning table. The fastening means 22 is preferably a threaded stud.
Examples
This embodiment is shown in fig. 1, including fixing base 1 and location platform 2, the two all adopts the aluminum alloy to make, is equipped with 8 evenly distributed's screw hole and 8 evenly distributed's locating pin on the fixing base, and the internal diameter of screw is 10mm, and the locating pin diameter also is 10mm, and open at the fixing base center has diameter 40 mm's centrally located hole.
The positioning table is provided with the same threaded holes and positioning pin holes corresponding to the fixed seat, and a positioning boss with the diameter of 40mm and the height of 20mm is arranged below the positioning table. A threaded column with the diameter of 40mm, the height of 20mm and the thread pitch of 1.5mm is arranged above the positioning table and used for fixing a machined workpiece. When the positioning table is used, the fixing seat is fixed on a machine tool, then the positioning table is fixed on the fixing seat through screws, and a product to be processed is fixed on the positioning table through the threaded columns. After the first hole on the hemispherical shell is arranged and machined, the next machining hole can be positioned by adjusting the relative position of the threaded hole on the positioning table (manually adjusting the relative position of the upper threaded hole of the positioning table by disassembling and assembling the screw), so that the machining is repeated, and finally, the machining is completed.
