Description
Technical field
The present invention relates to the special demounting tool device of a kind of Special Category rotary encoder breakdown maintenance, particularly a kind of encoder demounting tool.
Background technology
Siemens Servo motor built-in encoder have employed the special rotary encoder of German Heidenhain, and encoder main body is connected with bonnet to be designed to win and coordinates pressing to seal, and designs without detaching structure.Encoder bonnet connected mode is shown in attached sheet schematic diagram.When encoder break down needs uncap carry out inspection repair time, dismounting rear end cap just seem very difficult, if there is no special specific purpose tool, only have destroy end cover structure enough can open bonnet, cause sealing property to reduce; And coder structure is accurate, groove glass code-disc is frangible in addition, very likely causes irreversible damage, causes encoder to scrap.
Therefore a kind of a kind of instrument steadily can disassembling built-in encoder rear end cap is smoothly needed.
Summary of the invention
In view of this, technical problem to be solved by this invention is to provide a kind of instrument steadily can disassembling built-in encoder rear end cap smoothly.
The object of the present invention is achieved like this:
A kind of encoder demounting tool provided by the invention, the claw pulling cylinder and external screw thread matches with it the outer sleeve that comprise the two pieces of semicircular cylinders synthesis be sheathed on the cannelure of encoder are combined into drawing supporting construction assembly, and forward position and the encoder cannelure of claw pulling cylinder match; Described outer sleeve side is provided with additional screws; Described additional screws one end is interacted by the rotation of additional screws and outer sleeve; Described outer sleeve opposite side is connected with cannelure.
Further, described outer sleeve is also provided with push rod bolt and bonnet nut, and described push rod bolt is arranged on outer sleeve, and described push rod bolt is connected with the bonnet nut be arranged on bonnet through the through hole of encoder.
Further, pulling claw cover and top pawl is also comprised; Described top pawl is arranged at the cannelure side of encoder; Described pulling claw cover is arranged between outer sleeve and top pawl, and described top pawl is used for fastening cannelure two side plane and withstands bonnet.
Further, also spanner is comprised; Described spanner is arranged at the push rod bolt place on outer sleeve.
Further, rotation push rod bolt can promote top pawl simultaneously and encoder bonnet nut acts on encoder bonnet, moves after making it.
Further, push rod bolt thread rotation direction and encoder bonnet its thread rotation direction are oppositely arranged, and can prevent the ineffective power of the bonnet nut derotation.
Further, also comprise peep hole, described peep hole is arranged on outer sleeve.
Beneficial effect of the present invention is: the present invention adopts stressed the pushing away of multi-spot balancing to pull out formula structure, and dismounting bonnet mode of operation is simple, and unloading process can can't harm.The aid that the rear end cap that the present invention may be used for Siemens Servo motor built-in encoder is disassembled.Harmless the disassembling of code device end cap shell can be realized, steadily can disassemble built-in encoder rear end cap smoothly.Solve servomotor built-in encoder bonnet and be difficult to the problem disassembling maintenance, for feasible condition is created in the reparation of built-in encoder.According to encoder fault statistics, more than 70% is caused by coding disk pollutes, and mostly can recover to use through cleaning.Due to motor specific coding device costly, and delivery cycle is longer, repairs by aid, has considerable economic worth and application and popularization value.
