Abstract

The utility model relates to a milling flutes frock that adaptation camshaft work piece is fixed. When the tail portion of an existing groove milling tool compresses a workpiece, the front end of a cam shaft can be tilted by a certain height, and the symmetry degree of a groove is unqualified after the groove milling at the tail end is caused. The utility model discloses a base, the both ends on base upper portion set up the mount pad respectively, set up dismantled and assembled and transversal arrangement's sleeve on the first mount pad, telescopic center sets up the dowel, sets up on the second mount pad and compresses tightly the frock. The utility model discloses with the plane of front end location plus pin location structure, the change is the location structure of sleeve plus pin location. The structural improvement can carry out circumferential limit on the front end of the workpiece, so that the front end cannot be tilted after the tail end of the workpiece is pressed, and the workpiece cannot rotate at an angular direction; the symmetry and angle of the tail end groove are effectively and reliably ensured.

Description

Milling groove tool suitable for fixing camshaft workpiece

Technical Field

The utility model relates to a milling flutes frock that adaptation camshaft work piece is fixed.

Background

The existing milling groove tool comprises a base, the front end of the base is used for positioning a camshaft only through a plane and a limiting pin, the rear end of the base is used for compressing a workpiece through a pressing block, after the camshaft is clamped, the front end of the camshaft is only used for positioning the pin angularly, the circumference of the camshaft is not fixed, and therefore when the tail portion of the camshaft compresses tightly, the front end of the camshaft can be tilted by a certain height, and after the tail end milling groove is formed, the symmetry degree of the groove is unqualified.

SUMMERY OF THE UTILITY MODEL

The utility model discloses shortcoming to prior art exists provides an adaptation fixed milling flutes frock of camshaft work piece, can guarantee the angle and the symmetry in tail end groove after the processing under the prerequisite of assembly strength guaranteeing, is fit for fixing the camshaft of multiple different specifications.

Therefore, the utility model adopts the following technical proposal: the utility model provides a milling flutes frock that adaptation camshaft work piece is fixed which characterized in that includes the base, and the both ends on base upper portion set up the mount pad respectively, set up dismantled and assembled and transverse arrangement's sleeve on the first mount pad, telescopic center sets up the shop bolt, sets up on the second mount pad and compresses tightly the frock.

The middle part of the base is also provided with at least one supporting mechanism, and the upper and lower heights of the supporting mechanism are adjustable.

The supporting mechanism comprises a telescopic sleeve structure at the lower part, and a supporting clamping jaw is arranged at the upper part of the telescopic sleeve structure.

The base on close on the region of first mount pad including the outside both sides symmetry side by side set up a plurality of mounting holes, the inside and outside both sides of first mount pad set up fixed block and retaining member respectively and the mounting hole connect.

The base set up the spout in the left and right sides direction, telescopic sleeve structure form the slide rail in the bottom with the spout match.

The beneficial effects of the utility model reside in that:

1. the positioning structure for positioning the plane with the pin at the front end is changed into the positioning structure for positioning the sleeve with the pin. The structural improvement can carry out circumferential limit on the front end of the workpiece, so that the front end cannot be tilted after the tail end of the workpiece is pressed, and the workpiece cannot rotate at an angular direction; the symmetry and angle of the tail end groove are effectively and reliably ensured.

2. The sleeve is of a detachable structure so as to be convenient for replacing camshafts matched with different diameters.

3. A supporting mechanism capable of adjusting the height up and down is added in the middle of the base. The upper end of the supporting mechanism adopts a claw structure to better support and clamp the workpiece, so that the workpiece is prevented from deviating and reliably fixed.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is the structure diagram of the sleeve pin positioning of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a milling flutes frock that adaptation camshaft work piece is fixed, including base 1, the both ends on base upper portion set up the mount pad respectively, set up horizontal sleeve 4 on first mount pad 2, telescopic center sets up dowel 5, sets up on the second mount pad 3 and compresses tightly frock 7, the base on close to the region of first mount pad including outer both sides symmetry side by side set up a plurality of mounting holes 15, the inside and outside both sides of first mount pad set up fixed block 13 and retaining member 14 respectively and the mounting hole connect.

The middle part of the base is also provided with at least one supporting mechanism, and the upper and lower heights of the supporting mechanism can be adjusted. The supporting mechanism comprises a telescopic sleeve structure at the lower part, and a supporting claw 11 is arranged at the upper part of the telescopic sleeve structure. The telescopic sleeve structure comprises a hollow outer cylinder 8 and an inner cylinder 9 arranged in the outer cylinder, and locking pieces 10 are arranged on two sides of the outer cylinder to lock the extension length of the inner cylinder. The base is provided with a sliding groove 12 locally between the two mounting seats, and the bottom of the telescopic sleeve structure forms a sliding rail matched with the sliding groove.

The utility model discloses with the plane of front end location plus pin location structure, the change is the location structure of sleeve plus pin location. The structural improvement can carry out circumferential limit on the front end of the workpiece 6, so that after the tail end of the workpiece is pressed, the front end cannot be tilted, and the workpiece is ensured not to rotate at an angular direction; the symmetry and angle of the tail end groove are effectively and reliably ensured.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
