Abstract

The utility model discloses a cam shaft keyseat clamp which comprises a base (1). Two supportive blocks (2) are arranged on the base (1). The two supportive blocks (2) are provided with clamp grooves (3) for a cam shaft (4) to be placed. At least a clamping mechanism (5) for clamping the cam shaft (4) tightly is arranged on the base (1). The clamping mechanism (5) comprises a drive cylinder (6) which is fixedly connected with the base (1). A free end of a piston rod of the drive cylinder (6) is connected with a press rod (7) in a rotation mode. The bottom end of a free end of the press rod (7) is provided with a press head (9) which can tightly press the cam shaft (4). A connection rod (8) is hinged in the middle of the press rod (7). The lower end of the connection rod (8) is hinged with the base (1). When the cam shaft keyseat clamp clamps or a cam shaft is replaced, operation is convenient, time and labor are saved and clamping is fastened.

Description

Camshaft keyseat fixture
Technical field
The utility model relates to the Machining Technology field, specifically be a kind of camshaft keyseat fixture.
Background technology
Camshaft is a kind of vitals for automobile engine, and its structure generally comprises main shaft, and described main shaft is provided with the cam of a plurality of different angles, and the end of main shaft is provided with keyway.Therefore directly affect the installation accuracy of camshaft due to the horizontal level of keyway, camshaft will be clamped firm position when milling the keyway of camshaft, cause the position of keyway on main shaft deviation to occur in order to avoid the camshaft location skew occurs.Its structure of fixture that prior art is used for the camshaft keyseat generally comprises base, described base is provided with two back-up blocks, described two back-up blocks are provided with the draw-in groove of placing for camshaft, also be provided with the clamp mechanism that clamps camshaft on described base, described clamp mechanism comprises two clamping plate, and two clamping plate connect by leading screw, when clamping camshaft, camshaft is placed between two clamping plate, rotational lead screw then, thus make clamping plate clamp camshaft; The camshaft keyseat fixture of this structure operates comparatively inconvenience when clamping or change camshaft, and clamps unstablely, and the process of clamping wastes time and energy, inefficiency.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of and clamps or easy to operate, time saving and energy saving when changing camshaft, and clamp firmly camshaft keyseat fixture.
technical solution of the present utility model is, a kind of camshaft keyseat fixture with following structure is provided: it comprises base, described base is provided with two back-up blocks, described two back-up blocks are provided with the draw-in groove of placing for camshaft, at least be provided with a clamp mechanism that clamps camshaft on described base, described clamp mechanism comprises the driving cylinder that is fixedly connected with base, the free end of the piston rod of the described driving cylinder depression bar that is rotatably connected, be provided with the pressure head of a compression camshaft bottom the free end of described depression bar, and the hinged connecting rod in the middle part of depression bar, lower end and the base of described connecting rod are hinged.
After adopting above structure, the utility model camshaft keyseat fixture compared with prior art, have the following advantages: when this camshaft keyseat fixture is placed on camshaft on the base support piece in clamping, the action of driving cylinder, the piston rod that drives cylinder upwards promotes depression bar, the free end of depression bar rotates and makes the free-ended pressure head of depression bar compress the camshaft for the treatment of keyseat, keyway mill complete after, the piston rod that drives cylinder pulls down down-pressed pole, thereby make pressure head break away from camshaft, camshaft just can conveniently take off like this.Therefore the utility model camshaft keyseat fixture clamps or is easy to operate, time saving and energy saving when changing camshaft, and clamps firmly.
As a kind of improvement, connect a push rod that vertically arranges on described base, the cam bottom of the camshaft in the free end of described push rod and the draw-in groove that is placed on back-up block offsets.This push rod plays and supports the effect that holds out against camshaft, can prevent from rotating at the process convexity wheel shaft of keyseat, improves the positional precision of keyseat.
As a kind of improvement, the lower end of described push rod is connected with base by thread.The height on push rod top can be regulated, so that the top of push rod can hold out against the cam bottom of camshaft.
The top of described pressure head is provided with threaded shank, and the free end of described depression bar is provided with a screwed hole that matches with the threaded shank of pressure head, and described threaded shank is threaded with screwed hole.Rotary press head can be regulated the free-ended distance of pressure head and depression bar, thereby makes pressure head compress better camshaft.
