Any-angle indexing mechanism

Abstract

The invention discloses an any-angle indexing mechanism. The any-angle indexing mechanism comprises a transmission mechanism, a gear shifting mechanism and a reinforcement indexing mechanism; the transmission mechanism comprises a transmission shaft, a first bevel gear, a second bevel gear, a third bevel gear and a fourth bevel gear; the gear shifting mechanism comprises an indexing inner gear and an indexing outer gear which are arranged up and down; and the reinforcement indexing mechanism comprises a fifth bevel gear, a sixth bevel gear, a reinforcement shaft, an indexing disc, a bearing disc, a brake disc, a pull ring body and a transition disc. The any-angle indexing mechanism has the gear shifting function, can be used for designing an A shaft of an accessory head, achieves the speed reducing and force increasing effects of indexing motion of the A shaft of the accessory head, achieves the automatic clamping loosening and automatic indexing functions of the A shaft of the accessory head, and has the advantages of high indexing precision, stable indexing, small load and the like. The any-angle indexing mechanism has the advantages that the overall size is small; and for a large system using the indexing mechanism, the additional size is not increased, the cost needed for providing driving force is not increased, and meanwhile, the positioning precision of the system can be greatly improved.

Description

technical field [0001] The invention relates to an accessory head fitting of a machining center, in particular to an arbitrary angle indexing and indexing mechanism. Background technique [0002] The A-axis indexing mechanism of the accessory head on the market generally has the problems of large indexing load and inaccurate positioning. A-axis indexing load is heavy, problems such as crawling and jamming will occur during indexing, which directly lead to inaccurate positioning. In the design and product processing that require precise positioning, this is a very serious problem and often increases Equipment failure rate. Some designs also use the method of increasing the driving force torque. Although increasing the driving force torque can overcome the friction loss during the A-axis indexing and make the A-axis rotate smoothly, it will bring about the problems of oversized drive mechanism and high cost. Contents of the invention [0003] The technical problem to be so...

A-axis indexing load is heavy, problems such as crawling and jamming will occur during indexing, which directly lead to inaccurate positioning. In the design and product processing that require precise positioning, this is a very serious problem and often increases Equipment failure rate

Some designs also use the method of increasing the driving force torque. Although increasing the driving force torque can overcome the friction loss when the A-axis rotates and make the A-axis rotate smoothly, it will bring about the problems of excessive size and high cost of the driving mechanism.
