Embodiment

Embodiment

To make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings 1~5 and real Example is applied to be described in further detail the utility model.

One kind is simple, efficiently changes toothed tool, and the movable teeth block 2 on drive roll 1 for changing multiple roll furnace discharge conveyer is described Drive roll 1 divides to be coaxially disposed for left, center, right roller, three, and the diameter of central roll 102 is more than left and right roller, is provided with central roll 102 Six T-slots 3, each T-slot 3 is axially arranged along drive roll 1, and six T-slots 3 are uniform along the circumferencial direction of drive roll 1 Distribution, is provided with 19 the movable teeth blocks 2 and left and right sprue 4, left and right sprue 4 is set respectively in each T-slot 3 In the left and right side of 19 movable teeth blocks 2, limited block 5 is provided with the both ends of the surface of each T-slot 3, for fixed activity Tooth block 2 and left and right sprue 4, prevent movable teeth block 2 and left and right sprue 4 from being slided in T-slot 3；It is provided with left and right roller Six grooves 6, groove 6 are corresponded with T-slot 3, communicated, and the width of groove 6 is identical with the bottom width of T-slot 3, left, Right roller is arranged in bush seat 8 by bearing shell 7, the bearing shell 7 and bush seat 8 be 180 ° to opening structure, each bearing shell 7 by Upper and lower bearing shell 7 is formed, and each bush seat 8 is made up of upper and lower bush seat 8, and drive roll 1 is by the hydraulic motor that is connected with right roller 103 9 driving rotations, boss 10 is provided with the outer end of right roller 103；

The toothed tool that changes is characterized in that：Including tool changing block 11 and fixed seat 12, described tool changing block 11 is stripe shape, with When just changing tooth, tool changing block 11 can be placed in T-slot 3 and groove 6, and the one end of tool changing block 11 is inclined-plane 111；Described fixed seat 12 Middle part be push broach body 121, the bottom surface of push broach body 121 is engaged with the first half of right roller 103, and the inner of push broach body 121 is spiral shell Curved surface 122 is revolved, the inclined-plane 111 of the spiral camber 122 and tool changing block 11 is tangent, and tool changing block 11 is with drive roll during to change tooth 1 be rotated under the effect of spiral camber 122 is moved, and the process that the tool changing block 11 moves is more than or equal to a movable teeth block 2 Length；The both sides of fixed seat 12 are fixed plate 123, and fixed seat 12 is fixed on down by the fixed plate 123 of its both sides when changing tooth In bush seat 8.

The pitch of the spiral camber of described push broach body is P, lead angle δ, the length of described movable teeth block is L, Width is B, and the inclined-plane angle of described tool changing block is θ, and θ is acute angle, the relational expression between them：P>2L+2Bsin θ, θ= δ；Ensure simultaneously during tooth is changed, i.e., in the rotary course of drive roll 1, the not upper surface with the both sides of bearing shell 7 all the time of tool changing block 11 It is in contact.

Beeline between described lower bearing seat and T-slot end face is S, and the shortest length of described tool changing block is H, Then H>S.

With reference to this example demonstrates that using process：

Preparation：The top bearing shell seat 8 and top bearing shell 7 being arranged on left and right roller are removed, and will be of the present utility model solid Reservation 12 is fixed on the lower bearing seat 8 on right roller 102 by fixed plate 123.

Change tooth process：Removing needs to change the limited block 5 and left and right sprue 4 at the both ends of T-slot 3 at tooth, by new activity It is in tooth block 2 is put into the T-slot 3 communicates groove 6 and adjacent with the outside of the movable teeth block 2 in T-slot 3, then by this reality Be put into new tool changing block 11 in the groove 6 that is communicated with the T-slot 3 and with the outside phase of the new movable teeth block 2 Neighbour, the inclined-plane 111 of tool changing block 11 and the spiral camber 122 of push broach body 121 are tangent, now the spiral camber of push broach body 121 herein 122 apart from the outer face of T-slot 3 farther out, this is initial position；

Drive drive roll 1 to rotate forward by hydraulic motor 9, make the inclined-plane 111 of tool changing block 11 and the spiral of push broach body 121 The tangent of curved surface 122 is more and more nearer apart from the outer face of T-slot 3, enters with stylish movable teeth block 2 under the promotion of tool changing block 11 Enter in T-slot 3, a movable teeth block 2 of the other end of T-slot 3 is pushed out；

Drive drive roll 1 to reversely rotate to initial position by hydraulic motor 9, be put into new movable teeth block 2, then pass through liquid Pressure motor 9 drives drive roll 1 to rotate forward, then new movable teeth block 2 enters in T-slot 3 under the promotion of tool changing block 11, T-shaped One movable teeth block 2 of the other end of groove 3 is pushed out；

This process is circulated up to all replacings of the movable teeth block 2 in this T-slot 3, is then sequentially placed at the both ends of T-slot 3 Sprue 4 and fixed limited block 5, then the completion of tooth process is changed in this T-slot 3, method can be changed in other T-slots 3 successively like this Movable teeth block 2, until whole T-slots 3 in movable teeth block 2 be replaced.
