Abstract
The invention discloses an electric cylinder push-pull force limit testing mechanism. The mechanism comprises a base where an electric cylinder is installed, a support seat disposed on the base, a guide rod which is in a slide fit with the support seat and is coaxial with a telescopic rod of the electric cylinder, a pull pressure sensor connected with the guide rod, and a first spring which sleeves the guide rod and locates between the support seat and the pull pressure sensor; and one end, close to the pull pressure sensor, of the guide rod is provided with a first spacer matching an end portion of the first spring. According to the electric cylinder push-pull force limit testing mechanism, the electric cylinder is installed on the base when detection is performed, the telescopic rod of the electric cylinder is connected with the pull pressure sensor, and the electric cylinder is started then; and, when a limit push force of the electric cylinder is tested, the telescopic rod of the electric cylinder stretches forward to push the pull pressure sensor to compress the first spring, and then the push force of the electric cylinder is detected by the pull pressure sensor, so the detection is convenient, the structure of the detection device is simple, and manufacturing cost and operation cost are low.
Description
Technical field
The present invention relates to a kind of electric cylinder proving installation, particularly a kind of device testing electric cylinder limit push-pull effort.
Background technology
Electric cylinder is a kind of mechanism motor rotary motion being converted to rectilinear motion by ball-screw.The limit push-pull effort of electric cylinder is the important indicator weighing electric cylinder performance, needs during fabrication to detect electric cylinder limit push-pull effort.
But the device price of existing test electric cylinder limit push-pull effort is more expensive, and testing cost is high.
Summary of the invention
In view of this, the object of this invention is to provide a kind of electric cylinder push-pull effort limit test mechanism, to solve the test problem of electric cylinder limit push-pull effort.
Electric cylinder push-pull effort limit test mechanism of the present invention, comprise the pedestal of electric cylinder is installed, the bearing be arranged on pedestal coordinates with bearing sliding and the pull pressure sensor that is connected with guide pole of the guide pole coaxial with the expansion link of electric cylinder and the first spring of overlapping on the guide bar and between bearing and pull pressure sensor, described guide pole is provided with the first pad coordinated with the first spring end on one end of pull pressure sensor.
Further, described guide pole is also provided with the second spring, described first spring and the second spring lay respectively at the both sides of bearing, the end of described guide pole are provided with the second pad coordinated with the second spring end and the nut preventing the second pad from coming off.
Further, described pedestal is provided with the guide rail parallel with guide pole, described bearing settlement is on guide rail and coordinate with slide, and described guide rail is provided with inverted T-slot, is provided with the tommyhead bolt connecting bearing in described inverted T-slot.
Beneficial effect of the present invention:
Electric cylinder push-pull effort limit test mechanism of the present invention, during detection, electric cylinder is arranged on pedestal, the expansion link of electric cylinder is connected with pull pressure sensor, then open electric cylinder, during test electric cylinder limit thrust, the expansion link of electric cylinder protracts and promotes pull pressure sensor and compress the first spring, namely the thrust of electric cylinder detected by pull pressure sensor, easy to detect, and structure of the detecting device is simple, manufacture and operating cost low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment coiled material cutting machine automatic deviation rectifying device;
Fig. 2 is the syndeton schematic diagram of bearing and pedestal.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment electric cylinder push-pull effort limit test mechanism, comprise the pedestal 2 of electric cylinder 1 is installed, the bearing 3 be arranged on pedestal coordinates with bearing sliding and the pull pressure sensor 5 that is connected with guide pole of the guide pole 4 coaxial with the expansion link of electric cylinder and the first spring 6 of overlapping on the guide bar and between bearing and pull pressure sensor, described guide pole is provided with the first pad 7 coordinated with the first spring end on one end of pull pressure sensor, pad can make the first spring in a circumferential direction accept evenly.
The present embodiment electric cylinder push-pull effort limit test mechanism, during detection, electric cylinder is arranged on pedestal, the expansion link of electric cylinder is connected with pull pressure sensor, then open electric cylinder, during test electric cylinder limit thrust, the expansion link of electric cylinder protracts and promotes pull pressure sensor and compress the first spring, namely the thrust of electric cylinder detected by pull pressure sensor, easy to detect, and structure of the detecting device is simple, manufacture and operating cost low.
As the improvement to the present embodiment, described guide pole is also provided with the second spring 8, described first spring and the second spring lay respectively at the both sides of bearing, the end of described guide pole is provided with the second pad 9 coordinated with the second spring end and the nut 10 preventing the second pad from coming off, this improvement makes when needs test electric cylinder pulling force, opening electric cylinder makes the expansion link of electric cylinder bounce back, guide pole drives the second gasket compression second spring, pull pressure sensor detects by value of thrust, easy to detect.
As the improvement to the present embodiment, described pedestal is provided with the guide rail 11 parallel with guide pole, described bearing settlement is on guide rail and coordinate with slide, and described guide rail is provided with inverted T-slot, is provided with the tommyhead bolt 12 connecting bearing in described inverted T-slot; This improvement makes the installation site of bearing on pedestal reliable, thus can realize carrying out the detection of limit pressure to the electric cylinder of different stroke, and versatility is better.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
