Abstract
The utility model provides a cam clamping device, includes bottom plate, positioning seat, depression bar, uide bushing, handle, pivot, cam, compresses tightly seat, reset spring, the positioning seat with compress tightly the seat install side by side on the bottom plate, the uide bushing through the screw with compress tightly the seat be connected, the depression bar install the uide bushing and compress tightly the seat on, the handle is installed on the cam, the cam is installed in compressing tightly the seat through the pivot. In the depression bar passes the uide bushing and compresses tightly the cavity is connected of seat, install the reset spring who is compression state between boss terrace on the depression bar and the interior terminal surface of uide bushing. The utility model discloses compact structure, it is easy and simple to handle, pressing from both sides tightly the work piece, when relaxing the process, only needing just can realize through promoting or retract the handle, improved work piece machining efficiency, alleviateed operator's intensity of labour.
Description
Technical field
The utility model belongs to field of machining, is related to a kind of clamping device, more particularly to a kind of cam clamping device.
Background technology
It is well known that, it is necessary to carry out installation clamping to workpiece when being machined to workpiece on lathe, it is common to do
Method is clamped using pressing plate.Due to being limited by the shape of product and the structure of frock clamp, generally require to compress and fixed
Position device is arranged in the both sides of fixture, and workpiece is placed on fixture when using, and workpiece is clamped by pressing plate.But
It is that traditional pressing plate is difficult to fast-holding, usually makes troubles in actual use, causes operating efficiency low.Therefore,
Needing design one kind can meet processing request, while can make that operator is easy to operate, use efficient clamping device again.
Utility model content
The purpose of this utility model is to provide a kind of cam clamping device, is pulled manually or driving handle so that cam
Rotate and drive depression bar to move forward and backward be clamped workpiece and loosen, it is compact conformation, easy to operate, can lighten one's labor strong
Degree, can raise labour efficiency again.
To realize as above purpose, the technical solution adopted in the utility model is：A kind of cam clamping device, including base plate,
Positioning seat, depression bar, fairlead, handle, rotating shaft, cam, pressed seat, back-moving spring；Positioning seat and pressed seat are arranged on bottom side by side
On plate, fairlead is connected by screw with pressed seat, and depression bar is arranged on fairlead and pressed seat, and handle is arranged on cam
On, cam is arranged in pressed seat by rotating shaft.
In the cavity being connected with pressed seat through fairlead in depression bar, boss terrace and fairlead inner face on depression bar it
Between be provided with the back-moving spring of compressive state.
The utility model has following superiority using above-mentioned technical proposal：The utility model compact conformation, it is easy to operate,
To Workpiece clamping, loosen process when, only need to be can be achieved with by promoting or retracting handle, improve work pieces process efficiency, subtract
The light labour intensity of operator.
Brief description of the drawings
Fig. 1 is a kind of cross-sectional view of cam clamping device of the utility model.
Wherein：1. the cam 8. of 2. positioning seat of base plate, 3. depression bar, 4. fairlead, 5. handle, 6. rotating shaft 7.
The workpiece of 9. back-moving spring of pressed seat 10..
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.As shown in figure 1, a kind of cam clamping device, fixed
Position seat 2 and pressed seat 8 are arranged on base plate 1, and workpiece 10 is placed on positioning seat 2, and fairlead 4 is by screw and pressed seat 8
It is connected, depression bar 3 is slidably mounted on pressed seat 8 by the cylindrical hole of fairlead 4, handle 5 is arranged on cam 7, cam 7
It is arranged in the locating slot of pressed seat 8 by rotating shaft 6, back-moving spring 9 is arranged on the boss terrace of depression bar 3 and the end of fairlead 4
Between face, in compressive state, so as to promote curvilinear plane of the rear end face of depression bar 3 all the time with cam 7 to be in contact.
Its operation principle is：Positioning seat 2 and pressed seat 8 are arranged on base plate 1, and workpiece 10 is placed on positioning seat 2, are pushed away
The dynamic handle 5 on cam 7, cam 7 is rotated counterclockwise around the rotating shaft 6 installed in pressed seat 8, and cam 7 is contacted with depression bar 3
The radius increase of side, depression bar 3 is moved forward along the concentric curved section of the basic circle of cam 7 along fairlead, and back-moving spring 9 is compressed,
Until the contact workpiece 10 of depression bar 3 surface is no longer moved, so as to workpiece 10 be clamped, cam 7 can realize self-locking, prevent workpiece 10
Clamping is unstable.Conversely, retracting the handle 5 on cam 7, cam 7 is rotated clockwise around the rotating shaft 6 installed in pressed seat 8,
The radius that cam 7 contacts side with depression bar 3 reduces, and the resilience of back-moving spring 9 compressed makes depression bar 3 concentric along the basic circle of cam 7
Curved section is moved rearwards by along fairlead, until depression bar 3 is no longer moved rearwards by, so as to workpiece 10 be loosened.
Realize to Workpiece clamping, loosen process when, the clamping of workpiece need to be only can be achieved with by promoting or retracting handle
With loosen, compact conformation, operate nimble, improve work pieces process efficiency, mitigate the labour intensity of operator.
