Description

The saw blade guider

The utility model relates to a kind of saw blade guider, especially for the saw blade guider of the band saw that goes in ring.

In the guider of existing saw blade, generally adopt the brake pad guide way to control the swing of saw blade all around, concrete structure is to open sulculus on friction piece one, when making saw blade motion, passes through from sulculus, reaches the guiding purpose.But in the sawing process, the material of cutting constantly travels forward, and makes saw blade back produce very big frictional force, causes unnecessary power loss, has reduced the life-span of saw blade; Simultaneously, frictional force also makes the sulculus of brake pad guide way deepen and broadens, and loses guiding accuracy, therefore, must often change guide way and saw blade.

The purpose of this utility model is to provide a kind of saw blade guider of being done guide way by directive wheel.

The purpose of this utility model is achieved in that bearing pin is housed on the guide holder, and the rear end of bearing pin is contained on the guide holder, and front end protrudes from outside the guide holder, and directive wheel is housed, and the directive wheel outside is equipped with plain cushion, elastic collar successively; Guide holder one end is connected with guide type shoe, and backing pin shaft is housed on the guide type shoe, and an end of backing pin shaft is contained on the guide type shoe, and the other end protrudes in outside the guide type shoe, and a directive wheel is housed, and a directive wheel outside is equipped with a plain cushion, bearing elastic collar according to this; Have groove in the middle of propping up directive wheel.

Advantage of the present utility model is: improve the service time and the guiding accuracy of saw blade guider, prolong the service life of saw blade.

Below in conjunction with drawings and Examples the utility model is elaborated

Fig. 1 is the utility model embodiment master TV structure schematic diagram

Fig. 2 is the utility model embodiment side-looking structural representation

Fig. 3 is the utility model embodiment user mode schematic diagram

Embodiment 1: this routine described saw blade guider, as accompanying drawing 1,2, shown in 3, bearing pin (62) is housed on the guide holder (61), the rear end of bearing pin (62) is contained on the guide holder (61), front end protrudes from outside the guide holder (61), and the directive wheel (63) that rolling bearing is formed is housed, plain cushion (64) is equipped with in directive wheel (63) outside successively, elastic collar (66), the two is used for directive wheel (63) location, bearing pin (62), directive wheel (63) is a pair of and be arranged in parallel, gapped between two directive wheels (63), guide holder (61) one sides are equipped with trip bolt (66), are used for bearing pin (62) location; Guide holder (61) one ends are connected with guide type shoe (67), backing pin shaft (68) is housed on the guide type shoe (67), one end of backing pin shaft (68) is contained on the guide type shoe (67), the other end protrudes from outside the guide type shoe (67), and a directive wheel (69) is housed, propping up directive wheel (69) is made up of rolling bearing, and both sides are provided with seal cover, prevent the intrusion of water dust, prop up directive wheel (69) outside plain cushion (691), an elastic collar (692) are housed according to this, prop up plain cushion (691) and place in the seal cover, be used for directive wheel (a 69) location with an elastic collar (692); Prop up directive wheel (69) and become " product " word arrangement with a pair of directive wheel (63), have groove (693) in the middle of propping up directive wheel (69), groove (693) center is consistent with two directive wheels (63) centre joint, to guarantee that saw blade passes through smoothly, guide type shoe (67) one sides are equipped with a trip bolt (671), are used for backing pin shaft (68) location.

Embodiment 2: this example is that with the difference of embodiment 1 directive wheel (63), a directive wheel (69) are made up of sliding bearing.

(6) two of saw blade guiders are a cover, direction is installed in the upper and lower of workbench (8) on the contrary during use, on the be installed in guiding pull bar (1) on top, on the frame below the be installed in workbench of bottom (8), by adjusting the length that bearing pin (62) protrudes and the front and back position of guide type shoe (67), promptly applicable to the saw blade of different in width.
