DETAILED DESCRIPTION

[0018] The technical scheme in the embodiment of the utility model will be clearly and completely described below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] The double-column horizontal band saw machine is a common metal cutting machining equipment, the workbench 3 is provided with a T-shaped groove 4 for fixing a workpiece, and machining is facilitated. But the structural characteristics of the T-shaped groove 4 determine that the internal space is narrow, and there are multiple corners, which is easy to cause the accumulation of iron filings, grease and other impurities, and is difficult to clean, which affects the precision of clamping and the service life of the equipment.

[0020] The existing device for cleaning the T-shaped groove 4 mainly includes a manual tool and a simple dust collector, but the manual cleaning efficiency is low and it is difficult to clean the inaccessible parts in the groove; the simple dust collector has insufficient suction and cannot effectively remove the impurities attached to the wall of the T-shaped groove 4.

[0021] To solve the above technical problems, please refer to Figure 1 The embodiment provides a double-column horizontal band sawing machine, which comprises a chassis 1, a sawing mechanism 2 arranged on the chassis 1, the sawing mechanism 2 comprising a saw blade for sawing workpieces and a driving source for driving the saw blade to move back and forth, a workbench 3 installed on the chassis 1, a plurality of T-shaped grooves 4 formed in the upper side of the workbench 3 along a first direction, a clamping piece 5 arranged on the workbench 3 and matched with the T-shaped grooves 4, the clamping piece 5 being installed on the workbench 3 through cooperation of the T-shaped grooves 4 and the clamping piece 5, and a cleaning mechanism 6 arranged on the workbench 3 and used for cleaning iron filings in the workbench 3 and the T-shaped grooves 4.

[0022] The first direction is along the width direction of the T-shaped groove 4, in the application, the first direction is parallel to the moving direction of the saw blade, and Figure 1 It can be known that the first direction is the transverse direction of the workbench 3.

[0023] Please refer to Figure 2 and Figure 3 The cleaning mechanism 6 comprises a T-shaped block 61 matched with the T-shaped groove 4, brush hairs are installed on the circumferential side of the T-shaped block 61, a cross rod 62 is fixedly installed on the upper side of each T-shaped block 61, the cross rod 62 is located above the workbench 3, and a driving part 63 for driving the cross rod 62 to move along a second direction is arranged on the workbench 3.

[0024] The second direction is along the length direction of the T-shaped groove 4, in the application, the second direction is perpendicular to the moving direction of the saw blade, and Figure 1 It can be known that the second direction is the longitudinal direction of the workbench 3.

[0025] The T-shaped block 61 matched with the T-shaped groove 4 is arranged on the workbench 3, brush hairs are installed on the circumferential side of the T-shaped block 61, and the T-shaped block 61 can effectively clean the iron filings and sundries in the T-shaped groove 4. A cross rod 62 is fixedly installed on the top of each T-shaped block 61, the cross rod 62 can be driven by the driving part 63 on the workbench 3 to move along the second direction, so that the cross rod 62 can cover the T-shaped groove 4 of the entire workbench 3 and realize comprehensive cleaning of the T-shaped groove 4.

[0026] Please refer to Figure 2 and Figure 3The driving part 63 comprises sliding blocks 631 fixedly installed on both sides of the cross bar 62, threaded holes 632 are formed in the sliding blocks 631, threaded rods 633 are threadedly arranged in the threaded holes 632, and the two threaded rods 633 are connected through transmission members 634.

[0027] The two sliding blocks 631 are driven to move cooperatively by the sliding blocks 631 fixedly installed on both sides of the cross bar 62 and the threaded rods 633 arranged in the threaded holes 632 of the sliding blocks 631 and the transmission members 634, so that the cross bar 62 moves in the second direction. Specifically, the driving motor 635 drives one of the threaded rods 633 to rotate, and the two threaded rods 633 are driven to rotate synchronously through the transmission members 634, and the rotating directions of the two threaded rods 633 are the same. Since the threaded rods 633 are threadedly connected with the sliding blocks 631, and the two sliding blocks 631 are fixedly connected with the cross bar 62, the threaded rods 633 drive the sliding blocks 631 to move in the second direction. Since the rotating speeds of the two threaded rods 633 are the same, the moving speeds of the two sliding blocks 631 are the same, and the cross bar 62 and the T-shaped block 61 are in a translational state, so that the iron filings in the T-shaped groove 4 on the upper side of the workbench 3 are cleaned.

[0028] Please refer to Figure 2 and Figure 3 The transmission member 634 comprises a gear 636 fixedly installed on one side of the threaded rod 633, and the two gears 636 are provided with a toothed belt 637.

[0029] The rotating speeds of the two gears 636 are the same through the toothed belt 637, and the rotating speeds of the two threaded rods 633 are the same.

[0030] Please refer to Figure 2 and Figure 3 The workbench 3 is fixedly provided with a support frame 7, the support frame 7 is provided with a through hole, and the threaded rod 633 passes through the through hole.

[0031] The support frame 7 is used for supporting the threaded rod 633 and limiting the movement of the threaded rod 633, so that the threaded rod 633 does not move in the translational direction when the sliding blocks 631 are driven to move.

[0032] Please refer to Figure 2 and Figure 3The workbench 3 is fixedly provided with a protective shell 8 covering the transmission member 634. Since the gear 636 and the toothed belt 637 have high engagement accuracy, if machining iron filings enter between the toothed belt 637 and the gear 636, the rotational speed of the two threaded rods 633 will have errors, thereby affecting the dislocation of the moving positions of the two sliding blocks 631, and further affecting the translation of the horizontal rod 62. Therefore, the transmission member 634 needs to be protected to prevent iron filings from entering between the toothed belt 637 and the gear 636.

[0033] The clamping member 5 is connected with the workbench 3 through a bolt 9, the head of the bolt 9 is located in the T-shaped groove 4, and the bolt 9 is connected with the clamping member 5 through the T-shaped groove 4. The clamping member 5 clamps the workpiece to be machined, and the bolt 9 fastens the clamping member 5 and the workbench 3, mainly through the interaction force between the head and the inner wall of the T-shaped groove 4.

[0034] The horizontal rod 62 is fixedly provided with a plurality of brush plates 10 on the lower side in the first direction, the brush plates 10 are located between the two T-shaped blocks 61, and the brush plates 10 are fixedly provided with brush hairs on the lower side. During the movement of the horizontal rod 62, the brush plates 10 clean the iron filings on the upper side of the workbench 3.

[0035] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
