Description

Pushing mechanism of clamping mechanism

This creation department has a push-up structure for a clamping mechanism, especially a function that can assist the worktable to smoothly detach without generating noise.

Press, for semi-automatic or fully automatic machining, it is important that the carrier carrying the workpiece is properly clamped to the chuck or completely released. For example, if the carrier is not properly positioned on the chuck, there is a risk of misalignment of the workpiece during machining, resulting in inaccurate deviations in the dimensional accuracy of the workpiece, and of course extreme damage.

This type of clamping mechanism is a "floating type clamping mechanism" of the Taiwan Patent Publication No. I580514, which is provided by the creator, and has a working stage and a chuck, and is provided with a clamping on the bottom surface of the working stage. a clamping rod that is coupled to the working stage in a release or clamping action, wherein the clamping head includes a base centrally formed as a moving chamber, the open end of the base locking a top seat, and The movable chamber of the base is provided with a piston seat, and the ring between the piston seat and the top seat is provided with a plurality of elastic members for supporting the piston seat, and a movable seat is arranged in the center of the piston seat, and a ring is arranged on the outer side of the top of the movable seat. The inclined surface is limited to the opening of the top seat, and a horizontally displaced moving clamp is arranged around the movable seat, and then a base body is arranged at the bottom of the piston seat; thereby, the clamping rod of the working stage is embedded in the movable seat, and the moving body is moved The clamping member moves the clamping clamp rod inwardly, and at the same time, the movable seat floats upward, and the movable seat ring slopes and the top seat opening act to push the movable seat downwardly to firmly hold the clamping rod to reach the working stage. With the clamp zero point clamping effect.

It can be seen from the above structure that the machining effect of the stable clamping can be provided after the clamping is completed, and when the machining is completed, the input pressure is pushed against the piston seat to rise and loosely clamped, so that the clamping bar of the working stage can be separated from the activity. Clips on the seat. However, when the working stage and the collet of the general clamping mechanism are clamped to each other, the two corresponding end faces are flattened and attached, so that a vacuum fit state is formed between the two clamping bodies, so that the piston seat is raised and lowered. At the time of holding, the adsorption force of the two will produce a separation noise, which makes it somewhat unsatisfactory in use.

Today, the creator has been adhering to the rich design and development and practical production experience of the relevant industry for many years, and specially provides a push-up structure of the clamping mechanism, in order to achieve better practical value.

The main purpose of the present invention is to provide a pushing structure of a clamping mechanism, especially a function that can assist the worktable to smoothly detach without generating noise.

The main purpose and effect of the push structure of the creation clamping mechanism are achieved by the following specific technical means:

The utility model mainly comprises a working platform and a chuck, a clamping rod is arranged on the bottom surface of the working platform and is correspondingly embedded in the chuck, a piston seat is arranged in the chuck, and a piston seat is arranged in the center of the piston seat. a movable seat for the clamping rod to be embedded, and a base body is disposed at the bottom of the piston seat corresponding to the movable seat, the base body is provided with a boss, and the boss can lift and release the piston seat When the clamping bar of the working platform is provided, a thrust is provided to enable the working stage to smoothly disengage from the chuck; thereby, the auxiliary working stage can be smoothly separated without causing noise.

A preferred embodiment of the pushing structure of the clamping mechanism as described above, wherein the piston seat and the base body are two separate components.

A preferred embodiment of the pushing structure of the clamping mechanism as described above, wherein the piston seat is integral with the base body.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

First, please refer to the first to third figures, which is a schematic cross-sectional view of the pushing structure of the creation clamping mechanism, which is mainly provided with a working stage (1), which is provided on the bottom surface of the working stage (1) There is a clamping rod (11) correspondingly embedded in a chuck (2), a piston seat (21) is arranged in the chuck (2), and a constant hole (211) is arranged in the center of the piston seat (21). And a base body (22) is disposed at the bottom to seal the through hole (211), and a movable seat (23) is disposed in the through hole (211), and the movable seat (23) is centrally provided for the clip The rod (11) is embedded, and a clamping member (24) for clamping the clamping rod (11) is disposed around the movable seat (23), and the ring is arranged around the piston seat (21). a resilient member (25) for supporting the piston seat (21) to lift and lower the piston rod (21) to release and clamp the clamping rod (11) of the working stage, wherein:

a through hole (231) is disposed at a bottom of the center of the movable seat (23), and a boss (221) is disposed at the base body (22) corresponding to the through hole (231), the boss (221) The lifting displacement of the clamping rod (11) can be pushed up correspondingly.

Please refer to the first to third figures together, the clip member (24) of the present invention may be a slider or a ball, which is represented by a ball pattern; when the work stage (1) has not been correspondingly When the chuck (2) is inserted into the clamp, the piston seat (21) is input to the inner space of the chuck (2) through a power [using hydraulic oil pressure], and the piston seat (21) is presented The top support state [that is, the normally open state]. When the clamping rod (11) of the working stage (1) is embedded in the chuck (2), the power is released in the chuck, and the elastic member on the piston seat (21) (25) Stretching the elastic force to push and push the piston seat (21) downward, and when the piston seat (21) moves downward, the clamping jaw (24) is displaced toward the center and is locked. The clamping rod (11) is arranged to pull the movable seat (23) downward to take the clamping clamping rod (11), and at the same time, the bottom surface of the working stage (1) and the top surface of the chuck (2) can be They are closely attached to each other to achieve the zero clamping function of the work stage (1) and the chuck (2).

Continuing, when the machining is completed and the work stage (1) is disengaged from the chuck (2), a power is input to the inside of the chuck (2) to cause the piston seat (21) to rise and compress elastically. And (25) pushing the movable seat to rise slightly, and the clamping member (24) is displaced outwardly and disengaged from the clamping rod (11), and at the same time, due to the piston seat (21) The rising together drives the base body (22) to rise and displace, and pushes the clamping rod (11) by the boss (221) of the base body (22) to make the bottom surface of the working stage (1) Disengaged from the top surface of the chuck (2) to release the adhesive state, so that the work stage (1) can be smoothly separated from the chuck.

Further, the piston seat (21) and the base body (22) may be synchronously linked by two independent components [as described above], or the piston seat (21) may be integrated with the base body (22).

However, the above-described embodiments or drawings are not intended to limit the product, the structure, or the use of the present invention. Any changes or modifications of the ordinary skill in the art should be considered as not departing from the scope of the invention.
