Fig. 2 is a multifunctional portable type belt sander vertical view.
Fig. 3 is the locating wheel annex map.
In Fig. 1 to Fig. 3:
The 1-contact wheel, the 2-abrasive band, the 3-operating grip, the 4-regulating wheel, 5-tensioning support, 6-alignment pin 7-driving wheel, the 8-motor transmission shaft, the 9-stage clip, the 10-tension cam, the 11-supporting wheel, the 12-connecting rod, the 13-fore-stock, the 14-lock-screw, the 15-motor, the 16-casing, the 17-screw, the 18-stage clip, the 19-pin, 20-locating wheel annex, 21-regulates bolt, the 22-spring, the 23-side stand, the 24-bogie wheel, the 25-screw, the 26-screw, 27-presses nog plate flat surface grinding annex, 28-L type annex.
The utility model is described in further detail below in conjunction with accompanying drawing:
The abrasive band tensioning directly influences the quality of belt sander grinding, is in the required tensioning state of grinding for keeping the abrasive band, and the utility model has adopted static and dynamic two kinds of strainers.The static tensioning in abrasive band is achieved in that unclamps lock-screw [14], connecting rod [12] can move in the locating slot of casing [16] backward, after putting endless abrasive belt, rotate tension cam, make tensioning support [5] rotate, regulating wheel depressed that another section curve on the tension cam [10] leans connecting rod [12] afterbody simultaneously around axle [6], and promote contact wheel [1], make contact wheel [1] tighten the abrasive band; Lock-screw [14] is fixed in connecting rod within casing [16] chute, thereby realizes static tensioning, and with tension cam [10] cycle original place, cam leaves the tensioning support then.Block in the dynamic tension in abrasive band is achieved in that stage clip [9] one ends and is fixed on casing [16] is connected, the other end is connected with tensioning support [5], thereby tensioning support [5] is produced pressure, pass to regulating wheel [4], thereby realize the abrasive band dynamic tension by tensioning support [5].Make abrasive band [2] in the process of processing, also can keep good tensioning state, guarantee crudy.
Require abrasive band [2] and contact wheel [1] fine identical during grinding so that give full play to the ablation in abrasive band, but the size of abrasive band [2] is discrepant, this can run from normal operating position abrasive band in the processing [2], in order to align position, abrasive band [2], the utility model is provided with abrasive band deviation mechanism, behind the rotary screw [17], the power that stage clip [18] between connecting rod and fore-stock [13] back side shield is produced makes fore-stock [13] rotate around pin [19], proofread and correct the position of abrasive band [2] on contact wheel [1] in this way, make abrasive band [2] and contact wheel [1] fine identical, after the levelling of position, abrasive band [2], fore-stock [13] is locked by screw [17].
In the processing of grinding steel plate weld seam or the grinding of need sizing, often because of operator's weight inequality of exerting oneself, the size of weld seam grinding is differed, for overcoming this drawback, the utility model adopts locating wheel annex [20], bolt [21] is regulated in rotation, make spring [22] the generation power between side stand [23] and the fore-stock [13], this power is when adjusting side stand [23] height, also adjusted the height of bogie wheel [25], by turn to two bolts [21], can make two bogie wheels [24] connect wheel trolley [1] have one the height, locate grinding thickness by this way, can guarantee weld seam or the grinding quality that needs sizing to process.
In order to strengthen the effect of flat surface grinding, on connecting rod [12], can install and press nog plate flat surface grinding annex [27], this position of pressing nog plate annex [27] is the closer to fore-stock [13], it is just outstanding more to be attached to the abrasive band of pressing nog plate [27] bottom surface, the dynamics of flat surface grinding is big more, adjust the fixed position of screw in chute, the height of adjustable seamless nog plate [27].
With screw L type annex [28] is fixed on the casing [16], clamps at bench vice or on lathe then, promptly can be used as desk-top sbrasive belt grinding polishing, also can be used as the precision grinding-polishing processing of outer garden.
The utility model is compared with prior art has following advantage:
1. can adjust flexibly tensioning and the position in abrasive band, the quality of grinding and efficient improve.
2. but sizing grinding improves the flat surface grinding effect simultaneously.
3. sbrasive belt grinding scope strengthens, and the increasing mode is versatile and flexible, and is widely applicable.Can be used for the in addition polishing on part surface of polishing, particularly stainless steel of various structural members and steel plate weld seam, and the grinding and buffing processing on plastics, furniture surface.
