Abstract
A square-hole chuck comprises a chuck body (2) and an insert (1), a square hole is formed in the middle of the insert (1), the dimension of the square hole is identical to the overall dimension of a part needing machining, the outer circle of the insert (1) is equal to an inner hole in one end of the chuck body (2), the outer diameter of the chuck body (2) is trapezoidal, and a round groove (2-1) with the depth smaller than the thickness of the insert (1) is formed in the big end portion. The square-hole chuck is characterized in that the insert (1) is in close fit with the round groove (2-1) of the chuck body (2). A ready-made chuck is mounted on a lathe to be grooved after simple processing and debugging, and the grooved chuck is used for clamping square parts for turning. Products subjected to turning can meet the requirement on geometric tolerance, production efficiency and rate of finished precuts are improved, and production cost can be reduced.
Description
Technical field
The present invention relates to a kind of turning attachment, particularly a kind of be used to processing the square hole chuck of square parts or eccentric element.
Background technology
Lathe is when processing square parts or eccentric element, clamping method commonly used is to adopt the indirect clamping of auxiliary clamp, or adopt chuck to carry out clamping, these installation way production efficiency in batch production is lower, and the product high for Geometrical Tolerance Principle can't guarantee its precision, and scrappage is too high.
Summary of the invention
For above problem, the purpose of this invention is to provide a kind of square hole chuck, directly the square shaped part carries out clamping, can guarantee the product that Geometrical Tolerance Principle is high, enhances productivity and yield rate, reduces production costs.
The technical solution used in the present invention is: a kind of square hole chuck, by chuck, with inserting, formed, inserting is the middle square hole of having opened, square hole size is consistent with the profile of the part that needs processing, the cylindrical of inserting is identical with the endoporus of chuck one end, and the external diameter of described chuck is trapezoidal, and enlarged head is arranged with a circular groove, groove depth, less than the thickness of inserting, is characterized in that: described circular groove tight fit of inserting with chuck.
On the cylindrical of described chuck, have a chuck fluting.
Described insert material is chromium 12.
It is described that to insert with chuck be that brazing is connected.
The present invention, be contained in ready-made chuck on lathe and carry out the simple chuck fluting of processing after debugging and be used for clamping square parts and get final product turning.Product after turning can guarantee Geometrical Tolerance Principle, has both improved production efficiency and yield rate, can reduce production costs again.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of inserting.
Fig. 3 is the schematic diagram of chuck.
Fig. 4 be insert and chuck assembling after structural representation.
The specific embodiment
By Fig. 1, known, a kind of square hole chuck, by chuck 2 with insert and 1 form, insert and 1 opened square hole in the middle of being, square hole size is consistent with the profile of the part that needs processing, and described inserting 1 is tight fit with chuck 2, and the cylindrical of chuck 2 is provided with the chuck 2-2 that slots.
By Fig. 2, being known, is the schematic diagram of inserting.1 cylindrical of inserting is identical with the endoporus of chuck 2 one ends, with Manufacture by line cutting, inserts 2, and insert material is chromium 12.
By Fig. 3, being known, is the schematic diagram of chuck.The external diameter of chuck 2 is trapezoidal, and enlarged head is arranged with a circular groove 2-1, and groove depth is less than inserting 1 thickness.
By Fig. 4, known, be insert and chuck assembling after structural representation.The end face of chuck 2 bores and the consistent hole of 1 excircle dimension of inserting, and hole depth rate 1 thickness of inserting is smaller, and making to insert 1 can just very tight putting into, and will insert 1 to carry out brazing after putting into chuck 2, before welding, to guarantee to insert 1 and chuck 2 between without any impurity; With line, cut to the chuck fluting 2-2 that welds, just formed square hole chuck shown in Figure 1.
This chuck is simple and easy to use in batch production, to the workman without too high specification requirement, very large quickening clamping speed, for form and position tolerance and the degree of eccentricity, require high product can reach volume production and guarantee, significantly improved production efficiency.
