Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of locking device of frock clamp, and structure is simple, drives briquetting to carry out locking adjustment to the irregular workpiece of multiple small level by telescopic cylinder, easy to operate, and accuracy is high again.
The utility model solves the technical scheme that its technical problem adopts: the locking device providing a kind of frock clamp, comprise clamp base, briquetting and locking platform, the upper surface of described locking platform is square structure, its midpoint near four limits is furnished with four identical locking slots respectively, its center position is installed with clamp base, the middle position place of described clamp base has through hole, bulb expansion link is vertically installed with in this through hole, the upper end of described bulb expansion link is connected with holder, four sidewalls of described holder such as all to have at the large and U-shaped breach of opening upwards, described U-shaped breach is embedded in and is furnished with protruding and relative with the locking slot briquetting in front end, the two side, middle part of every block briquetting has been arranged symmetrically with brace, one end and the briquetting of described brace are rotatedly connected, the other end is fixedly connected with clamp base.
One as locking device described in the utility model is supplemented, the center of described locking slot is furnished with locating hole I, the bilateral symmetry of described locating hole I is furnished with locating hole II, workpiece to be locked is placed in locking slot, by locating hole I and locating hole II, this workpiece is positioned, drive briquetting toward pressing down, until touch surface of the work and pushed down from telescopic cylinder again.
Another kind as locking device described in the utility model supplements, and the sidewall of described clamp base is in " convex " type, and the upper end in the middle part of it is connected with briquetting, and its both sides are connected with the one end of the brace being vertically close to briquetting.
A kind of supplementary as also having of locking device described in the utility model, the other end of described bulb expansion link is connected with telescopic cylinder, for the compression of briquetting provides power.
beneficial effect
The utility model relates to a kind of locking device of frock clamp, structure is simple, four pieces of briquettings are driven to carry out compression operation to the irregular workpiece of small level that four are positioned in corresponding locking slot respectively by telescopic cylinder, due to the effect of telescopic cylinder, enhance thrust, easy to operate, and accuracy is high; Further, this device can carry out compression operation to four workpiece simultaneously, and compare an original workpiece with regard to the one or more locking device of needs, this locking device saves the operating time greatly, has saved cost simultaneously.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 1-2, embodiment of the present utility model relates to a kind of locking device of frock clamp, comprise clamp base 1, briquetting 2 and locking platform 6, the upper surface of described locking platform 6 is square structure, its midpoint near four limits is furnished with four identical locking slots 7 respectively, its center position is installed with clamp base 1, the middle position place of described clamp base 1 has through hole 51, bulb expansion link 5 is vertically installed with in this through hole 51, the upper end of described bulb expansion link 5 is connected with holder 3, four sidewalls of described holder 3 such as all to have at the large and U-shaped breach 31 of opening upwards, described U-shaped breach 31 is embedded in and is furnished with protruding and relative with locking slot 7 briquetting in front end 2, the two side, middle part of every block briquetting 2 has been arranged symmetrically with brace 4, one end and the briquetting 2 of described brace 4 are rotatedly connected, the other end is fixedly connected with clamp base 1.
The center of described locking slot 7 is furnished with locating hole I 71, and the bilateral symmetry of described locating hole I 71 is furnished with locating hole II 72.
The sidewall of described clamp base 1 is in " convex " type, and the upper end in the middle part of it is connected with briquetting 2, and its both sides are connected with the one end of the brace 4 being vertically close to briquetting 2.
The other end of described bulb expansion link 5 is connected with telescopic cylinder.
Embodiment
Four workpiece to be locked are laid respectively in four locking slots 7 first on locking platform 6, and with the locating hole I 71 in locking slot 7 and locating hole II 72, corresponding workpiece is positioned, then telescopic cylinder is started, holder 3 is driven up to move by bulb expansion link 5, now, the briquetting be rotationally connected with brace 42 starts down to rotate, four briquettings 2 rotate until contact with the upper surface of workpiece simultaneously, and tightly push down workpiece, because the coupling mechanism force of telescopic cylinder is comparatively large, so can play good effect to the locking of workpiece.
