Abstract
The utility model discloses a tensioning device of a band sawing machine and aims to solve the problem that tensioning slide blocks of the existing band sawing machines are easy to wear due to the threaded holes, causing frequent replacement which is time-consuming and labor-consuming and increases production cost, on the slide blocks. The tensioning device comprises a slide block which is slidably disposed on a band sawing machine body through a pressing block. The slide block is provided with a fixing hole matched with a rotary shaft of a driven wheel of the band sawing machine. A nut is embedded on the slide block. The thread axis direction of the nut is consistent with the sliding direction of the slide block. A slot corresponding to the thread axis of the nut is reserved on the slide block. An adjusting bolt sequentially penetrates through a through hole on the band sawing machine body and the slot to be matched with the nut in a threaded manner. The nut is added in the slot of the slide block, the adjusting bolt is matched with the nut directly in a threaded manner, and accordingly when the thread of the nut is worn, a user can only replace the nut. In addition, the tensioning device is simple and fast to operate, timesaving and laborsaving, and lowers production cost.
Description
Technical field:
The utility model belongs to tension equipment, is specifically related to a kind of tensioning apparatus of band sawing machine.
Background technology:
Existing band sawing machine mainly is to realize by the slide block that slip is located on the lathe bed to the tensioning work of bands for band, one side of described slide block is provided with that the glide direction along slide block is provided with screwed hole on the side of the fixing hole in mating connection with the rotating shaft of the driven pulley of band sawing machine, opposite side, be provided with adjusting bolt in the screwed hole, the nut of adjusting bolt is in outside the fixed dam of lathe bed, the screwed hole that slide block is passed through on it by the rotation adjusting bolt outwards slides along the external screw thread on the adjusting bolt, and then make driven pulley outwards mobile, thereby realize the tensioning to bands for band.But owing to being sliding friction between slide block and the adjusting bolt, the screw thread that both match is fragile because of the tension force that is subjected to saw blade, so just need to change continually adjusting bolt and slide block, and the replacing program of slide block is loaded down with trivial details, the parts such as driven pulley and rotating shaft, slide block all need to be dismantled, present every dismounting once needs 30-60 minute, wastes time and energy, greatly increase maintenance worker's labour intensity, also increased production cost simultaneously.
Summary of the invention:
The utility model is for overcoming the deficiencies in the prior art, and a kind of easy and simple to handle, tensioning apparatus of being convenient to change damaged part, time saving and energy saving band sawing machine is provided,
The purpose of this utility model is achieved in the following ways: the tensioning apparatus of this band sawing machine, comprising slides by briquetting is located at slide block on the band sawing machine lathe bed, described slide block is provided with the fixing hole that matches with the rotating shaft of the driven pulley of band sawing machine, the technical scheme that adopts is: be inlaid with nut on the slide block, the screw thread axis direction of nut is consistent with the glide direction of slide block, place, the screw thread axle center of corresponding nut offers slotted eye on the slide block, and through hole and slotted eye that adjusting bolt is passed on the band sawing machine lathe bed successively cooperate with nut thread.
As further improvement of the utility model, described nut is polygon, slotted eye be circular or polygonal any one.
As further improvement of the utility model, described slotted eye is polygon, nut be circular or polygonal any one.
The beneficial effects of the utility model are: the tensioning apparatus of this band sawing machine, have additional nut in the slotted eye on slide block, adjusting bolt directly cooperates with nut thread, like this behind the thread abrasion of nut, only needing to change nut gets final product, it is simple and efficient to handle, time saving and energy saving, and has reduced production cost.
Description of drawings:
Fig. 1 is package assembly schematic diagram of the present utility model.
Fig. 2 is disassemblying structure schematic diagram of the present utility model.
The specific embodiment:
See figures.1.and.2, the tensioning apparatus of this band sawing machine, comprising slides by briquetting 6 is located at slide block 2 on the band sawing machine lathe bed 1, described slide block 2 is provided with the fixing hole 5 that matches with the rotating shaft of the driven pulley of band sawing machine, be inlaid with nut 3 on the slide block 2, the screw thread axis direction of nut 3 is consistent with the glide direction of slide block 2, and place, the screw thread axle center of corresponding nut 3 offers slotted eye on the slide block 2, and adjusting bolt 4 is passed through hole and slotted eye and nut 3 threaded engagement on the band sawing machine lathe bed 1 successively.Nut 3 in this specific embodiment is polygon, slotted eye be circular or polygonal any one, perhaps slotted eye is polygon, nut 3 be circle or polygonal any one; Slide block 2 is provided with screw, and screw is provided with compressing tablet, and compressing tablet is pressed on the nut 3 to prevent that nut from taking off groove.When needing the bands for band on the tension band sawing machine, rotation adjusting bolt 4, make nut 3 along the external screw thread of adjusting bolt 4 and outwards slip, and then drive whole slide block 2 and outwards slide, because the fixing hole 5 on the slide block 2 is enclosed within the rotating shaft of driven pulley of band sawing machine, thereby it is outwards mobile to drop driven pulley, realizes the tensioning to bands for band.
