Description

The crawler type tool magazine improves structure

The utility model relates to crawler type tool magazine structure.

Tool magazine structure now mostly is used in the comprehensive process cutter, and the cutter suitable in order to automatic supply gives main shaft, reaches full-automatic production and processing.

General crawler type tool magazine mainly has a rack body, be pivoted with two sprocket wheels on the rack body, be arranged with chain between two sprocket wheels, and equidistant group is provided with carriage on chain, each carriage is provided with broach shell, cooperate motor department control sprocket rotation, and location structure watch control, make required broach shell arrive the location, cooperate colluding of tool-changing mechanism to get, make cutter in this broach shell be delivered to the main shaft of comprehensive process cutter, for main shaft processing working substance.

Above-mentioned crawler type tool magazine must be provided with two relative sprocket wheels, it is except that how part is tired of, and after using a period of time, its chain just can be relaxed state, especially at long-time bearing broach shell and cutting tool state, be with, this commonly uses the essential spacing of adjusting two sprocket wheels of mechanism, relegates to the category of things wanting precisely because adjust structure at all, perhaps adjusts quite inconvenient, so that overall structure can't be used for a long time or convenient the adjustment, and this is that the designer fails to take into account.

The purpose of this utility model provides a kind of crawler type tool magazine and improves structure, but the chain elasticity is adjusted on its simple and convenient ground, and has the advantages that to be convenient to keep in repair broach shell.

For achieving the above object, the crawler type tool magazine structure that the utility model provides, comprise rack body, its characteristics are that this rack body is provided with guide block, and the guide block periphery is provided with guide rail, in guide block, be provided with the adjustment plate that to adjust displacement, the motor and the location structure of one sprocket wheel, drive sprocket are set on this adjustment plate at least, and around covering chain, this chain can follow the standard of guide rail to move on sprocket wheel, the guide rail; Equidistant group is provided with carriage on the chain, and each carriage is provided with broach shell.

In addition, according to embodiment of the present utility model, its characteristics are that guide block and rack body are formed in one, and guide block also becomes the Contraband shape; The chain both sides are pivoted with roller, and this roller can follow guide rail to move; Rack body, adjustment plate are provided with the adjustment structure in relative position; The adjustment structure is included in rack body, adjustment plate relative position is established and adjusted groove, screw; Rack body, adjust the plate relative position and establish the adjustment piece, one adjusts piece has screwed togather two bolts, wherein a bolt be press on that another adjusts on piece, another bolt then runs through and is screwed together in this adjustment piece; Rack body is provided with some counterbores in the periphery of each broach shell, and pillar one end can overlap and be formed in the counterbore, and the screw lock of fitted bolt is fixed, and establishes press strip in pillar free end group, rack body at press strip, the pillar periphery then locks that guard shield is arranged; The chain both sides are provided with roller, and this roller can follow the standard of guide rail to move.

The utlity model has following advantage:

(1) the convenient elasticity of adjusting chain: adjust the plate slip because of it and adjust in the guide block of rack body, use one motion sprocket wheel, make the elasticity of chain watch control for adjusting structure, its adjustment is quite easy, and has the benefit that multiplies each other of simplicity to promote.

(2) reduce the number of part: it only needs a sprocket wheel can drive the chain rotation, really can significantly simplify the cost of correlated parts, and reach economic advantage.

(3) the mat rack body is integrated structure in guide block, thus can strengthen the tool magazine whole rigidity, improve quality and significantly alleviate gross weight, to reach cost and the technology that material, reduction group are established of saving.

For making the auditor can further understand structure of the present utility model, feature and other purposes, attached now with the graphic detailed description of preferred embodiment as the back:

Fig. 1 is front elevational schematic of the present utility model (being not organize the state of establishing motor and located in connection structure).

Fig. 2 is a schematic side view of the present utility model.

Fig. 3 is a schematic top plan view of the present utility model.

Fig. 4 is the utility model rack body, the decomposing schematic representation of adjusting plate, guard shield.

Fig. 5 is the utility model rack body, the combination schematic diagram of adjusting plate.

Fig. 6 is the utility model rack body, the adjustment structural representation of adjusting plate.

Please cooperate Fig. 1, Fig. 2 and shown in Figure 3, the utility model mainly has a rack body 10, rack body 10 is provided with Contraband shape guide block 100, guide block 100 peripheries are provided with guide rail 101, in guide block 100, be slidingly equipped with T shape adjustments plate 20 in addition, rack body 10, adjust plate 20 and be provided with the adjustment structure in relative position, make and adjust plate 20 easy displacement adjustment, one sprocket wheel 30 is set on this adjustment plate 20, the motor 31 and the location structure of drive sprocket 30, on the sprocket wheel 30, following two ends and guide rail 101 are rough contour, so that at sprocket wheel 30, on the guide rail 101 around covering chain 32, these chain 32 both sides also are pivoted with roller 321, but make chain 32 mat rollers 321 and follow the standard of guide rail 101 to move, be with, the utility model need only be provided with a sprocket wheel 30, the relative structure that cooperates guide rail 101 and roller 321 again can drive sprocket wheel 32 and rotate, by this to reach the advantage that structure is simplified.

Equidistant group is provided with carriage 33 on the chain 32, each carriage 33 is provided with broach shell 34, cooperate motor 31 departments control sprocket wheel 30 to rotate, reach the control of watching of location structure, make required broach shell 34 arrive the location, cooperate colluding of tool-changing mechanism 35 to get, make cutter in this broach shell 34 can be delivered to the main shaft of comprehensive process cutter.

Please cooperate Fig. 4, Fig. 5 and shown in Figure 6, this adjustment structure mainly respectively is provided with and adjusts groove 11, screw 21 at rack body 10, adjustment plate 20 relative positions, makes adjustment plate 20 adjustable adjusting be arranged in rack body 10 with the restriction that cooperates guide block 100; Rack body 10, adjustment plate 20 relative positions respectively are provided with the L shape and adjust

piece
