Description

Adjustable center frame

Technical Field

The utility model belongs to the technical field of whirlwind milling machining and specifically relates to a whirlwind milling machining technique of car, milling combined machining specifically is an adjustable centre frame.

Background

The field of domestic machining is rapidly developing, and the whirling milling is a high-speed thread milling device matched with a common lathe, and a thread machining method for milling threads from a workpiece by using a hard alloy forming cutter arranged on a high-speed rotating cutter head. Generally, when a long-axis workpiece is machined, the clamping device does not firmly support the workpiece, and even the workpiece is loosened or obviously vibrated due to insufficient clamping degree, so that the final machining precision is affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: the adjustable center frame comprises a mounting frame at the bottom, and cylinder supporting plates are fixed at two ends of the mounting frame; the guide rail is positioned on the mounting rack; still including removing the slider, remove the slider set up in the both ends of guide rail, the upper surface is vertical to be fixed with two slider supports.

Preferably, a dustproof device is connected between the movable sliding blocks, and the dustproof device is of an organ-shaped laminated structure and covers the guide rail.

Preferably, the sliding block support further comprises a replaceable fixing block, and the replaceable fixing block is installed at the top end of the sliding block support.

Preferably, a gasket is arranged between the replaceable fixing block and the sliding block bracket.

Preferably, the air cylinder fixing device further comprises a fixing air cylinder and an adjustable air cylinder, wherein the fixing air cylinder is installed on the air cylinder supporting plate and arranged at one end of the mounting frame, the adjustable air cylinder is installed at the other end of the mounting frame, and the fixing air cylinder and the adjustable air cylinder are respectively connected with the movable sliding block.

Preferably, the device further comprises an adjusting device, and the adjusting device is connected with the cylinder supporting plate.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model has the advantages that the clamping and assembling of the workpiece are accurate and firm by matching the cylinders at the two sides with the sliding blocks and the guide rails, and the mode of tightly pushing the fixing piece reduces the dependence on the rigidity of the bracket when the long-axis workpiece is processed; and the vibration force generated by the cutter during cutting is transferred to the lathe bed through the clamping block, so that the cutting of complex parts is smoothly realized.

Drawings

FIG. 1 is an overall structure diagram of the present invention;

in the figure: the device comprises a mounting frame 1, a cylinder supporting plate 2, a guide rail 3, a movable sliding block 4, a sliding block bracket 5, a dustproof device 6, a replaceable fixed block 7, a gasket 8, a fixed cylinder 9, an adjustable cylinder 10 and an adjusting device 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, an adjustable center frame includes a bottom mounting frame 1, and cylinder supporting plates 2 are fixed at two ends of the mounting frame 1; the mounting frame also comprises a guide rail 3, and the guide rail 3 is positioned on the mounting frame 1; still including removing slider 4, remove slider 4 set up in the both ends of guide rail 3, the upper surface is vertical to be fixed with two slider supports 5.

And a dustproof device 6 is connected between the movable sliding blocks 4, and the dustproof device 6 is of an organ-shaped laminated structure and covers the guide rail 3. The sliding block support is characterized by further comprising a replaceable fixing block 7, wherein the replaceable fixing block 7 is installed at the top end of the sliding block support 5. A gasket 8 is arranged between the replaceable fixed block 7 and the sliding block bracket 5. Still include fixed cylinder 9 and adjustable cylinder 10, fixed cylinder 9 install in on the cylinder backup pad 2, arrange in 1 one end of mounting bracket, adjustable cylinder 10 install in the 1 other end of mounting bracket, the two respectively with remove slider 4 and be connected. The device further comprises an adjusting device 11, and the adjusting device 11 is connected with the cylinder supporting plate 2.

To sum up, the utility model discloses at first through improve the structure that prior art well support supported the work piece, adopt both sides to set up cylinder and slider, make pressing from both sides of work piece adorn and become both ends clamp type by supporting the type, utilize guide rail 3 and removal slider 4, drive 7 relative movement of removable fixed block to adapt to the size of work piece and required press from both sides dress position, removable fixed block 7 adopts v type piece in the embodiment, can go into the v type recess with work piece both ends card, prevent to receive cutter vibration and slippage in the course of working. The adjusting device 11 at one end is used for finely adjusting the whole position of the clamping part after the clamping of the cylinders at two sides is finished, so that the machining and tool setting are facilitated. The dustproof devices 6 connected between the movable sliding blocks 4 are designed into organ shapes in consideration that flying chips and dust in the machining process can cover the guide rail 3 and influence the work of the movable sliding blocks 4, so that the dustproof devices 6 can stretch along with the movement of the sliding blocks, and the machining progress can not be influenced while protection is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
