Embodiment Construction

[0017] Specific embodiments of the present invention will be further described in detail below.

[0018] Such as figure 1 and figure 2 As shown, a fixture based on a linear motor of the present invention includes a machine base 10 on which a double-sided linear motor 12 is arranged. The linear motor 12 includes a primary 14 and a secondary 16 .

[0019] Both ends of the secondary 16 are respectively connected to a connecting rod 18 , and each connecting rod 18 is connected to a toggle mechanism 20 , 22 . The toggle mechanism 20 includes a pivotally connected first joint arm 24 and a second joint arm 26 , and the connecting rod 18 is pivotally connected to the connection point of the first joint arm 24 and the second joint arm 26 . The first joint arms 24 of the two toggle mechanisms 20 are pivotally fixed on the same point of the machine table 10 . A booster lever 28 is pivotally arranged on the machine table 10, and the free end of the second section arm 26 is pivotally c...

Abstract

The invention discloses a clamp with a linear motor. The clamp comprises a machine station, wherein a linear motor is arranged on the machine station, and comprises a primary stage and a secondary stage; the clamp is characterized by further comprising at least one toggle mechanism; the toggle mechanism comprises a first knuckle arm and a second knuckle arm which are pivotally connected with each other; connecting bars are pivotally arranged at the at least one end of the secondary stage; the other end of each connecting bar is pivotally connected to a pivotal point where the first knuckle arm and the second knuckle arm are connected; the free end of the first knuckle arm is pivotally fixed on the machine station; at least one sliding chute is formed in the machine station; slide blocks capable of moving along the sliding chute is arranged in the sliding chute; the free end of the second knuckle arm is pivotally connected to the slide blocks. The clamp provided by the invention felicitously utilizes the characteristics that after the toggle force-amplifying mechanism exceeds a critical point, power output can be greatly improved, and reliable self-locking and pressurizing can be realized, has a compact structure and comparatively complete functions, and is obvious in force-amplifying effect and high in efficiency.

Description

[0001] technical field [0002] The invention relates to a fixture based on a linear motor, especially a double-station fixture utilizing a toggle mechanism. Background technique [0003] Linear motor is a new type of motor, which can directly convert electrical energy into linear motion without any intermediate conversion mechanism. It has the advantages of no contact, no wear, low noise, high precision, good starting performance, convenient maintenance, and simple structure. It has broad application and development prospects. With the development of modern manufacturing industry, modern enterprises put forward higher requirements for transmission technology, such as high performance, low energy consumption, low wear, safety and comfort. The defects of the traditional hydraulic cylinder drive such as leakage and the noise of the traditional cylinder have become the bottleneck of its development. [0004] Usually, when the workpiece is processed, the fixture needs to prov...
