Abstract
The utility model relates to a demounting tool for the rotating head of an encoder. The demounting tool comprises wedge blocks, a bracket and a screw, wherein the bracket takes the shape of a frame; guide rails are arranged on two opposite inner sides of the bracket; a fixing seat and a nut seat are fixed on the other two opposite inner sides of the bracket respectively; the screw is mounted on the nut seat; a handle is mounted at one end of the screw; a connecting support is connected with the other end of the screw; grooves corresponding to the guide rails are formed in two ends of the connecting support; the two ends of the connecting support are clamped on the guide rails; and the wedge blocks are fixedly mounted on opposite sides of the connecting support and the fixing seat. The wedge blocks on two sides extrude to disengage the rotating head from a shaft, so that during the dismounting of the rotating head of the encoder, the precision of the encoder cannot be impacted. The demounting tool has a small and simple structure, and is convenient to manufacture, and low in cost.
Description
Technical field
The utility model relates to the maintenance of equipment instrument, is used for the dismounting of device coding device swivel head, specifically relates to encoder swivel head extracting tool.
Background technology
Now a lot of equipment all use rotary encoder, but are difficult for pulling down during the maintenance of encoder swivel head, and swivel head tightly is sleeved on the axle; With the gap of encoder body also very little (about 1mm); Do not have special-purpose maintenance tool, and when pulling down, can not use brute force, otherwise influence the precision of rotary encoder.
Summary of the invention
The utility model technical problem to be solved is, when the encoder swivel head is dismantled, do not damage the axle of encoder, also do not influence the precision of rotary encoder simultaneously.
The technical scheme of taking to the problems referred to above the utility model is that encoder swivel head extracting tool comprises: voussoir, support and screw rod; Support is a frame shape, and relative two inboards are provided with guide rail, and relative two inboards are fixed with holder and nut seat respectively in addition; Nut seat is equipped with screw rod, and an end of screw rod is equipped with handle, and the other end is connected with the connection bearing; Two ends that connect bearing are provided with and the corresponding groove of guide rail, and are installed on the guide rail, connect bearing and holder opposite face and are installed with voussoir.
Said voussoir is a wedge shape, and the centre is provided with open slot.
The utility model has the advantages that encoder swivel head extracting tool utilizes the power of the extruding of its two sides voussoir slowly to break away from swivel head with axle, when dismantling the encoder swivel head; Any influence can not arranged to the precision of encoder; This tool construction is small and exquisite, simple, and is easy to make, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be among Fig. 1 A-A to generalized section.
Fig. 3 is the front view of voussoir 1 among Fig. 1.
Fig. 4 is the side view of voussoir 1 among Fig. 1.
Among the figure: 1, voussoir, 2, support, 3, screw rod, 4, handle, 5, holder, 6, connect bearing, 7, guide rail, 8, nut seat.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is described further at present, referring to Fig. 1 to Fig. 4, encoder swivel head extracting tool; Comprise: voussoir 1, support 2 and screw rod 3, support 2 is a frame shape, and relative two inboards are provided with guide rail 7; Relative two inboards are fixed with holder 5 and nut seat 8 respectively in addition, and nut seat 8 is equipped with screw rod 3, and an end of screw rod 3 is equipped with handle 4; The other end is connected with and connects bearing 6; Two ends that connect bearing 6 are provided with and guide rail 7 corresponding grooves, and are installed on the guide rail 7, connect bearing 6 and are installed with voussoir 1 with holder 5 opposite faces.Said voussoir 1 is a wedge shape, and the centre is provided with open slot.
Embodiment:The voussoir 1 of the utility model is to be processed by hard material (like No. 45 steel), makes two groups of voussoir 1 appearance similars, and just thickness is different, and its middle groove width is than the big 0.1mm～1mm of diameter of the axle of encoder.It is corresponding parallel that support 2 relative two inboards are provided with guide rail 7, and two ends that connect bearing 6 are provided with groove, and are installed on the guide rail 7.During use; Voussoir 1 is filled in the inside, gap between swivel head and the encoder gently; Rotary handle 4 makes screw rod 3 drive connection bearing 6 gently; And make to be installed in and connect voussoir 1 that bearing 6 is and be installed in voussoir 1 relative motion on the holder 5, thereby the swivel head on the coder shaft is produced extruding, swivel head is produced with axle separate.After the gap progressively became big becoming flexible, replaceable thicker voussoir 1 continued to exert pressure, until the encoder swivel head is separated with axle.
