Description

Technical Field

[0001] This utility model relates to the field of gang saw technology, specifically to an adjustable saw frame for gang saws. Background Art

[0002] In existing technologies, the saw frame in a gang saw not only needs to have high structural strength, but also needs to be able to stably install the gang saw blade to avoid the cutting quality of the workpiece being affected by deviations in the gang saw accuracy. However, most existing saw frames are fixed and cannot be adjusted according to the length of the saw blade. Therefore, specific saw frames are required for different specifications of saw blades, which is not conducive to production.

[0003] Existing technology CN216992550U discloses an adjustable saw frame for gang saws, including a first saw blade clamping head, a second saw blade clamping head, and connecting plates installed on both sides of the first and second saw blade clamping heads. The first saw blade clamping head includes a clamping seat and a tensioning plate that cooperates with the clamping seat. The clamping seat includes a clamping seat body, clamping seat protrusions integrally formed on both sides of the clamping seat body, bolts welded to both sides of the clamping seat body, hydraulic cylinders embedded in the upper and lower ends of the clamping seat body and whose output ends are fixedly connected to the tensioning plate, and a clamping seat inner groove opened in the clamping seat body for accommodating saw blade connectors. This saw frame, by using the first saw blade clamping head, the second saw blade clamping head, and the connecting plates, can not only flexibly adjust the tension of the saw blade, but also adjust the distance between the first and second saw blade clamping heads on the connecting plates, which is beneficial for assembling saw blades of different specifications.

[0004] However, the aforementioned adjustable saw frame for gang saws adjusts the position by setting multiple adjustment holes on the connecting plate body to adjust the spacing between the first saw blade mounting head and the second saw blade mounting head, thereby adjusting the spacing between the saw blades. However, adjusting by using adjustment holes, with too many holes, not only reduces the strength of the connecting plate body, but also limits the range of saw blade position adjustment.

This solution increases the adjustment range of the mating position between the saw blades during processing and use. It is understood that this solution is beneficial for increasing the adjustment range of the mating position between the saw blades.

[0022] In this embodiment, the saw frame body 101 is installed at the installation positioning point of the equipment via the installation device.

[0023] The bearing housing 102 is detachably connected to the saw frame body 101 and is located at the bottom of both sides of the saw frame body 101. The rotating shaft 103 is rotatably disposed between the bearing housings 102. The rotating shaft 103 is symmetrically provided with rectangular keyways, and a flat key is provided in the rectangular keyway. The circular saw blade 104 is fitted on the rotating shaft 103, and the rectangular groove in its inner cavity is slidably engaged with the flat key. The spacer 105 is fitted on the rotating shaft 103, and the rectangular groove in its inner cavity is slidably engaged with the flat key, and is located on both sides of the circular saw blade 104. The left limiting nut 106 and the right limiting nut 107 are respectively screwed into the external thread end of the rotating shaft 103 and are located on one side of the spacer 105. The anti-loosening device is provided on both sides of the rotating shaft 103. The mounting device is provided on the top of the saw frame body 101. The bearing housing 102 is installed on both sides of the saw frame body 101 by positioning pins and bolts. The rotating shaft 103 is a stepped shaft with corresponding external thread ends on both sides. The external thread ends are located on both sides of the keyway opening end. The outermost mounting ends on both sides facilitate installation on the bearing housing 102 by rotating bearings. A flat key is provided in the keyway on the rotating shaft 103. The rectangular groove in the mounting hole of the circular saw blade 104 cooperates with the flat key to prevent the circular saw blade 104 from rotating on its own. The spacer 105 can be directly fitted on the outside of the rotating shaft 103. The rectangular groove on its inner side is in sliding cooperation with the flat key. The left limiting nut 106 and the right limiting nut 107 are screwed into the external thread ends on the rotating shaft 103 and can respectively abut against the end of the spacer 105 away from the circular saw blade 104. The anti-loosening device is used to improve the stability of the circular saw blade 104 after installation. The mounting device is used for installing the saw frame body 101.

[0024] Secondly, the left anti-loosening nut 108 is threadedly connected to the rotating shaft 103 and located on one side of the left limiting nut 106; the right anti-loosening nut 109 is threadedly connected to the rotating shaft 103 and located on one side of the right limiting nut 107. The left anti-loosening nut 108 and the right anti-loosening nut 109 can be directly installed on the corresponding external thread ends of the rotating shaft 103, respectively for anti-loosening treatment of the left limiting nut 106 and the right limiting nut 107.

[0025] Then, the left screw 110 is integrally formed with the saw frame body 101 and is located on the top left side of the saw frame body 101; the right screw 111 is integrally formed with the saw frame body 101 and is located on the right side of the saw frame body 101; the positioning component is disposed between the left screw 110 and the right screw 111. The integral formation of the left screw 110 and the right screw 111 with the saw frame body 101 ensures strength. During installation, they can pass through the through hole of the equipment mounting frame and be locked and fixed by a nut. The positioning component is used to improve the stability of the saw frame body 101 after installation.

[0026] Finally, the left positioning pin 112 is integrally formed with the saw frame body 101 and is located on the side of the saw frame body 101 near the left screw 110; the right positioning pin 113 is integrally formed with the saw frame body 101 and is located on the side of the saw frame body 101 near the right screw 111. The left positioning pin 112 and the right positioning pin 113 are used to improve the stability of the saw frame body 101 during installation.

[0027] When using this utility model to increase the adjustment range of the mating position between saw blades during processing, the saw frame body 101 is fixed to the installation positioning point of the equipment by the mounting device. Then, the rotating shaft 103 is connected to the equipment drive mechanism to facilitate rotation. During processing, the equipment drive mechanism operates, driving the rotating shaft 103 to rotate, thereby driving the two circular saw blades 104 to rotate for processing. When it is necessary to adjust the spacing between the saw blades, the left anti-loosening nut 108 and the right anti-loosening nut 109 can be loosened first, and then the left anti-loosening nut 109 can be loosened. The right limiting nut 106 or the right limiting nut 107 is used. Then, without the spacer 105 and the circular saw blade 104 abutting each other, the circular saw blade 104 can be directly pushed to move to adjust its position. After adjustment, the left limiting nut 106 or the right limiting nut 107 is tightened respectively. With the cooperation of the spacer 105, the circular saw blade 104 is limited. Finally, the anti-loosening device is tightened to complete the adjustment. Compared with the traditional method of adjusting the spacing through the adjustment hole, the adjustment range of this application is larger, thereby increasing the adjustment range of the mating position between the saw blades during processing and use.
