Abstract
The invention discloses a connecting rod thrust clamping device comprising a base, a cam arranged on the base and used as a force application device and a connecting rod for compacting a workpiece, wherein the driving end of the connecting rod supports against the cam after passing through a through hole, a cavity and a sliding chute which are arranged on the base in sequence; and the connecting rod located in the cavity is sleeved with a spring and provided with a round pin, and a limiting block is also arranged between the spring and the round pin. The defects of inconvenience in force application and incapability of accurately controlling the clamping force of a clamping jaw when an operator operates without a tool in the prior art are overcome; and the invention provides the improved connecting rod thrust clamping device by which the operator can manually operate a clamp conveniently to clamp a processed workpiece and the labor intensity of the operator can be relieved.
Description
Technical field
The invention belongs to clamping tool for machine work, particularly a kind of connecting rod thrust clamping device system.
Background technology
Fixture and grip device are widely known by the people, and are widely used for manufacturing; Particularly, fixture has various reference surfaces, and parts or instrument can accurately be located.In many process, to clamp member, be general, so that these parts can keep correct juxtaposition relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying.
For location and the clamping of miniature workpiece, usually adopt artificial free-hand completing in order to reduce costs, by utilizing lever, spring, pulley, cam, the combinations such as jaw reach the effect of clamping work pieces.Although existing clamping device can meet the clamping demand of workpiece to a certain extent, when operator's hand operation, there is application of force inconvenience, can't accurately hold jaw clamping dynamics.
Summary of the invention
Technical problem to be solved by this invention be in prior art when operator's hand operation, there is application of force inconvenience, can't accurately hold jaw clamping dynamics, connecting rod thrust clamping device after a kind of improve is provided, handled easily person manual operation fixture is clamped work piece, alleviates operative employee's labour intensity.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of connecting rod thrust clamping device, comprise pedestal, be arranged on pedestal and as the cam of force application apparatus with for the connecting rod of workpiece pressing, the drive end of connecting rod passes and is successively set on through hole, cavity and the chute on pedestal, thereby offsets with cam;
Wherein, be positioned on the connecting rod of cavity and be socketed with spring and be provided with round pin, also be provided with limited block between spring and round pin.
Adopt a kind of connecting rod thrust clamping device of technical solution of the present invention, as the cam driven connecting rod drive end of force application apparatus, the connecting rod driven end is clamped workpiece; Connecting rod in cavity is provided with limited block, can make the connecting rod can be because of excessive not moving and skid off the effect that cavity plays the limiting rod displacement, the spring be socketed on connecting rod can prevent that connecting rod is stuck in cavity, spring can make connecting rod after cam is cancelled the driving force to connecting rod simultaneously, connecting rod is resetted, and round pin is for retainer spring and limited block.
Further, described connecting rod driven end transverse weld has screw rod, can strengthen the area of fixture clamping work piece.
Further, described cam is provided with rocking bar, handled easily person operation of cam.
Operating process of the present invention is as follows: the rocking bar that the operator is provided with by driving cam, and drivening rod, connecting rod is clamped workpiece; After clamping finishes, the reverse operation rocking bar, cam is cancelled the driving force to connecting rod, and connecting rod can pass through spring reset.
The beneficial effect that the present invention has: 1, be arranged on the cam on pedestal, make the operator directly to pass through the cam wheel force application apparatus, can easily grasp fixture like this, avoid operator's hand operation fixture, alleviated operator's labour intensity; 2, be socketed limited block on the connecting rod in cavity, not only can limiting rod because of excessive the movement, skid off cavity, and can prevent after clamping, when connecting rod resets, because spring reset power is excessive, connecting rod skids off the situation of pedestal.
The accompanying drawing explanation
Fig. 1 is the novel structural representation of this use.
The specific embodiment
As shown in Fig. 1, the present invention is a kind of connecting rod thrust clamping device, comprise pedestal 1, be arranged on pedestal 1 and as the cam 2 of force application apparatus with for the connecting rod 3 of workpiece pressing, the drive end of described connecting rod 3 passes through hole 4, cavity 5 and the chute 6 arranged on pedestal 1 successively, thereby offsets with described cam 2;
Wherein, be positioned on the connecting rod 3 of cavity 5 and be socketed with spring 8 and be provided with round pin 7, between described spring 8 and round pin 7, also be provided with limited block 9, described connecting rod 3 driven end transverse weld have screw rod 10, and described cam 2 is provided with rocking bar 11.
In concrete enforcement, the operator is by the rocking bar 11 of driving cam 2, cam 2 drivening rods 3 then, and connecting rod 3 moves on through hole 4, cavity 5 and chute 6, drivening rod 3 driven end transverse weld have screw rod 10 finally and workpiece offsets is clamped, and screw rod 3 can strengthen the face with piece-holder;
Simultaneously, on the connecting rod 3 in cavity 5, be socketed with spring 8 and be provided with round pin 7, between described spring 8 and round pin 7, also be provided with limited block 9, the movement that limited block 9 can limiting rod 3, prevent connecting rod 3 because excessively movement skids off pedestal 1; Spring 8 can prevent that connecting rod is stuck in pedestal 1 when motion.
After clamping finishes, reverse operation rocking bar 11, cam 2 is cancelled the driving force to connecting rod 3, and connecting rod 3 can reset by the spring 8 of socket, when simultaneously limited block 9 can limiting rod 3 resets because spring 8 reset forces are excessive, thereby can avoid connecting rod 3 to skid off the situation of pedestal 1.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
