Abstract
Description
Technical field
The utility model relates to a kind of hold-down mechanism, refers in particular to a kind of hydraulic corner hold-down mechanism.
Background technology
In the development of modern industry, hold-down mechanism is widely used in various frock clamps.In prior art, conventionally adopt the corner cylinder of standard as corner hold-down mechanism, the defect of this corner cylinder is: chucking power is little, and cantilever is short.Take corner cylinder conventional on market as example, oil cylinder cylinder diameter≤φ 63, working pressure 70kg/cm 2time, theoretical chucking power≤650kgf, can not meet the requirement of the large-scale and heavy workpiece of clamping.
In view of the described defect of prior art corner cylinder, the inventor furthers investigate it, develops a kind of hydraulic corner hold-down mechanism that overcomes described defect, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic corner hold-down mechanism, to increase chucking power, and can add long cantilever.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of hydraulic corner hold-down mechanism, comprises mount pad, cantilever, rotating shaft, hydraulic cylinder and pushing block; On mount pad, form axial passage, on the sidewall of axial passage, pilot pin is set; Rotating shaft is movably arranged in axial passage, and on rotating shaft, forms interconnective spiral guide slot and axially directed groove, and pilot pin slides in spiral guide slot and axially directed groove; Cantilever is installed in rotating shaft one end, and the other end is installed pushing block in a rotatable manner; Hydraulic cylinder is arranged on mount pad, and the piston rod of hydraulic cylinder is connected with pushing block.
Further, this rotary way is: pushing block is arranged on the rotating shaft other end by taper roll bearing.
Further, roller is installed in pilot pin end, and this roller slides in spiral guide slot and axially directed groove.
Further, in mount pad, be provided with oil groove, inject lubricating oil by the oil nozzle being arranged on mount pad sidewall.
Adopt after such scheme, the utility model in use, hydraulic cylinder action, the pushing block that promotes to be fixed on hydraulic cylinder piston rod moves down, and pushing block pulls rotating shaft to move down, in moving process, the spiral guide slot of rotating shaft and axially directed groove and pilot pin mating reaction, make the first 90-degree rotation of rotating shaft, and then rectilinear motion, until the cantilever being arranged on rotating shaft is encountered workpiece, and then realize the compression to workpiece.Compared with prior art, it is large that it has chucking power, and cantilever such as can lengthen at the advantage, and theoretical chucking power maximum can improve approximately 50 times, and cantilever also can lengthen, and can reach cylinder diameter≤φ 250, working pressure 70kg/cm 2, theoretical chucking power 34360kgf.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 6, a kind of hydraulic corner hold-down mechanism that the utility model discloses, comprises mount pad 1, rotating shaft 2, cantilever 3, pushing block 4 and hydraulic cylinder 5.
On mount pad 1, form axial passage 11, pilot pin (in figure not label) is set on the sidewall of axial passage 11.
Rotating shaft 2 is movably arranged in axial passage 11, and on rotating shaft 2, forms interconnective spiral guide slot 21 and axially directed groove 22, and pilot pin slides in spiral guide slot 21 and axially directed groove 22.In the present embodiment, roller (not shown) is installed in pilot pin end, this roller slides in spiral guide slot 21 and axially directed groove 22, to improve the wearability of spiral guide slot 21 and axially directed groove 22.
Cantilever 3 is installed in rotating shaft 2 one end, and the other end is installed pushing block 4 in a rotatable manner; In the present embodiment, pushing block 4 is arranged on rotating shaft 2 other ends by taper roll bearing 6.
Hydraulic cylinder 5 is arranged on mount pad 1, and the piston rod 51 of hydraulic cylinder 5 is connected with pushing block 4.In the present embodiment, in mount pad 1, be provided with oil groove (in figure for illustrating), inject lubricating oil by the oil nozzle 12 being arranged on mount pad 1 sidewall, make whole mechanism kinematic smooth and easy.
The utility model in use, hydraulic cylinder 5 moves, the pushing block 4 that promotion is fixed on hydraulic cylinder 5 piston rods 51 moves down, pushing block 4 pulls rotating shaft 2 to move down, in moving process, and the spiral guide slot 21 of rotating shaft 2 and axially directed groove 22 and pilot pin mating reaction, make the first 90-degree rotation of rotating shaft 2, and then rectilinear motion, until the cantilever 3 being arranged on rotating shaft 2 is encountered workpiece, and then realize the compression to workpiece.Compared with prior art, it is large that it has chucking power, and cantilever such as can lengthen at the advantage.
The foregoing is only preferred embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
