Description

Milling tool for special-shaped slender shaft

Technical Field

The utility model relates to the field of clamps, in particular to a milling tool for a special-shaped slender shaft.

Background

The application of slender parts in industrial production is very wide, and for example, transmission shafts of automobiles, lead screws on machine tools, polish rods and the like belong to slender shafts. The general processing method of the slender shaft part is turning processing, but during the turning processing, bending deformation is easy to generate due to poor rigidity, and meanwhile, due to the influence of factors such as cutting force, cutting heat, vibration and the like, the straightness, cylindricity and the like of the slender shaft part generate large errors, so that the requirements of form and position precision and surface quality are difficult to achieve.

In the rough machining stage of the slender shaft part, the end face machining of the slender shaft part generally uses milling machining, one end of the existing slender shaft is a bent special-shaped end, the other end of the existing slender shaft is a straight rod end, the existing machining tool for the slender shaft can only clamp a single slender shaft, the existing clamp occupies a large space, the clamping mode is complex, and the production efficiency is low.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is: the milling tool for the special-shaped slender shafts can clamp a plurality of slender shafts at a time, occupies a small space, is simple to clamp, and improves production efficiency.

In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides a milling process frock of dysmorphism slender axles, has the base, open at the base middle part has a plurality of locating holes, open the lower part of base has a plurality of rectangular channels, every the locating hole side all is provided with positioning module, positioning module includes an L-shaped piece and two locating levers, every equal sliding connection has the clamp plate in the rectangular channel, every it has two arcs to open on the clamp plate, and leaves the clearance between clamp plate and the base.

Furthermore, a plurality of the locating holes are distributed on the base in a linear array mode, a plurality of the rectangular grooves are distributed on the base in a rectangular array mode, each rectangular groove is arranged corresponding to two locating holes, and the rectangular grooves are communicated with the locating holes.

Furthermore, the L-shaped block is in threaded connection with the upper portion of the base, the two positioning rods are in threaded connection with the base, and the two positioning rods are located on the left side and the right side of the L-shaped block.

The utility model has the beneficial effects that: through the cooperation use of base, locating hole, rectangular channel, L-shaped piece, locating lever, clamp plate and arc wall, can a plurality of slender axles of single centre gripping, occupation space is less, and the clamping is simple, improves production efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-6, the milling tool for the special-shaped slender shaft is provided with a base 1, the middle of the base 1 is provided with a plurality of positioning holes 2, the lower portion of the base 1 is provided with a plurality of rectangular grooves 3, each positioning module is arranged beside each positioning hole 2 and comprises an L-shaped block 401 and two positioning rods 402, each rectangular groove 3 is internally provided with a pressing plate 5 in a sliding connection mode, each pressing plate 5 is provided with two arc-shaped grooves 501, and a gap is reserved between each pressing plate 5 and the base 1.

The plurality of positioning holes 2 are distributed on the base 1 in a linear array mode, the plurality of rectangular grooves 3 are distributed on the base 1 in a rectangular array mode, each rectangular groove 3 corresponds to two positioning holes 2, and the rectangular grooves 3 are communicated with the positioning holes 2.

L-shaped block 401 and the upper portion threaded connection of base 1, two locating levers 402 and base 1 threaded connection, and two locating levers 402 are located the left and right sides of L-shaped block 401.

The working principle of the utility model is as follows: when the device is used, all the pressing plates 5 are driven by the external cylinder, the straight rod end of the slender shaft 7 is firstly inserted into the corresponding positioning hole 2 along the L-shaped block 401 and the two positioning rods 402 until the special-shaped end of the slender shaft 7 is attached to the L-shaped block 401, and then the external cylinder drives the pressing plates 5 to ascend to clamp the slender shaft, so that the end part of the straight rod end of the slender shaft can be machined.

The above examples are intended to further illustrate the present invention, but are not intended to limit the utility model to these specific embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
