Abstract
A plurality of shock absorbers 14 are disposed in parallel to each other in different positions on the left and right in a slide table 13 with push rods 14a for expanding and contracting projecting outside from opposite end faces of the slide table 13 in a moving direction of the slide table 13 and a plurality of stoppers 15 with which the respective push rods 14a collide at stroke ends of the slide table 13 are disposed in such positions at opposite end portions of the rail base 11 to face the respective shock absorbers 14.
Claims7
A linear actuator with a shock-absorbing mechanism, said actuator comprising:
- a rail base with open opposite ends without end walls standing upward from axial opposite end portions;
- a guide rail provided in an axial direction on said rail base;
- a slide table disposed on said rail base to linearly reciprocate along said guide rail;
- a driving mechanism for driving said slide table;
- a plurality of shock absorbers disposed in parallel to each other in different positions on the left and right in said slide table with push rods for expanding and contracting projecting outside from opposite end faces of said slide table in a moving direction of said slide table;
- and
- a plurality of stoppers which are disposed at said opposite end portions of said rail base to face said respective shock absorbers and with which said respective push rods collide at stroke ends of said slide table.
A linear actuator with a shock-absorbing mechanism, said actuator comprising:
- a rail base with open opposite ends without end walls standing upward from axial opposite end portions;
- a guide rail provided in an axial direction on said rail base;
- a slide table disposed on said rail base to linearly reciprocate along said guide rail;
- a driving mechanism for driving said slide table;
- a plurality of shock absorbers mounted to support blocks disposed in different positions on the left and right of said opposite end portions of said rail base with push rods for expanding and contracting oriented in such directions as to face each other;
- and
- stoppers formed in different positions on the left and right in said slide table and at such distances from opposite end faces of said slide table in a moving direction of said slide table that at least said shock absorbers out of said shock absorbers and said support blocks can enter said slide table, said push rods of said shock absorbers colliding with said stoppers at stroke ends of said slide table.
