Description

Protective device on vertical drilling machine

Technical Field

The utility model relates to a machining field especially relates to a protector on upright drill.

Background

The drilling machine is a machine tool which mainly uses a drill to machine a hole on a workpiece. Typically the drill bit is rotated into a primary motion and the drill bit is moved axially into a feed motion. The drilling machine is simple in structure, relatively low in machining precision, capable of drilling through holes and blind holes, replacing special cutters, and capable of expanding, reaming or tapping and the like. However, the debris generated during drilling can splash around as the drill bit rotates, and is prone to injury.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a protector on upright drill.

The utility model discloses a realize through following technical scheme: the utility model provides a protector on upright drill, includes the base, fixes stand on the base, fixes the cutter mechanism case on the stand top and with stand threaded connection's processing platform, the fixed surface of cutter mechanism case has the loading board, logical groove has been seted up on the loading board, set up the groove of stepping down with leading to the groove intercommunication on the inner wall that leads to the groove both sides, the inslot internal rotation of stepping down is connected with the gear, it has first guard plate to peg graft in the logical groove, the both sides of first guard plate are fixed with the rack respectively, and the rack meshes with the gear mutually, vertical dovetail slide has been seted up on the preceding inner wall in groove of stepping down, be fixed with the dovetail draw runner of sliding connection in dovetail slide on the first guard plate, be fixed with driving motor on the leading flank of loading board, driving motor's main shaft runs through loading board and gear shaft.

Further, leave the gap between the rear end face of first guard plate and the back inner wall that leads to the groove, be close to both sides department on the rear end face of first guard plate and articulate respectively has the second guard plate.

The utility model has the advantages that: when the drilling machine works, a workpiece is firstly placed on the processing table, the driving motor works at the moment, the driving motor drives the gear to rotate, and the gear is meshed with the rack, so that the rack can be driven to move downwards, the first protection plate can move downwards in the through groove to block the front of the drilling machine, and scrap iron generated during drilling can be blocked by the first protection plate in front, so that personal safety is protected; and when first guard plate reciprocated in logical inslot, the sliding fit relation of forked tail draw runner and forked tail spout can not make the rack on the first guard plate derail.

Drawings

Fig. 1 is a schematic front view of the present invention;

fig. 2 is a schematic top view of the present invention;

in the figure: 1. a base; 2. a column; 3. a cutter mechanism box; 4. a processing table; 5. a carrier plate; 6. a through groove; 7. a yielding groove; 8. a gear; 9. a first guard plate; 10. a rack; 11. a dovetail chute; 12. dovetail slide bars; 13. a drive motor; 14. and a second protection plate.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model comprises a base 1, a vertical column 2 fixed on the base 1, a cutter mechanism box 3 fixed on the top end of the vertical column 2 and a processing platform 4 connected with the vertical column 2 by screw thread, a bearing plate 5 is fixed on the surface of the cutter mechanism box 3, a through groove 6 is arranged on the bearing plate 5, the inner walls of the two sides of the through groove 6 are provided with a yielding groove 7 communicated with the through groove 6, the yielding groove 7 is rotationally connected with a gear 8, a first protection plate 9 is inserted in the through groove 6, racks 10 are respectively fixed on two sides of the first protection plate 9, the racks 10 are engaged with the gear 8, a vertical dovetail sliding groove 11 is arranged on the front inner wall of the abdicating groove 7, a dovetail sliding strip 12 which is connected in the dovetail sliding groove 11 in a sliding way is fixed on the first protection plate 9, a driving motor 13 is fixed on the front side surface of the bearing plate 5, and a main shaft of the driving motor 13 penetrates through the bearing plate 5 and is fixedly connected with a rotating shaft of the gear 8.

Therefore, when the drilling machine works, a workpiece is firstly placed on the processing table 4, the driving motor 13 works at the moment, the driving motor 13 works to drive the gear 8 to rotate, and the gear 8 is meshed with the rack 10, so that the rack 10 can be driven to move downwards, the first protection plate 9 is moved downwards from the inside of the through groove 6 to block the front of the drilling machine, and scrap iron generated during drilling can be blocked by the first protection plate 9 in front, so that personal safety is protected; when the first protection plate 9 moves up and down in the through groove 6, the rack 10 on the first protection plate 9 cannot be derailed due to the sliding fit relationship between the dovetail slide bar 12 and the dovetail slide groove 11.

Further, a gap is reserved between the rear end face of the first protection plate 9 and the rear inner wall of the through groove 6, and the positions, close to the two sides, of the rear end face of the first protection plate 9 are respectively hinged with a second protection plate 14. The thickness of the second protection plate 14 parallel to the first protection plate 9 is slightly smaller than the distance between the rear side surface of the first protection plate 9 and the rear inner wall of the through groove 6. So that when the first protection plate 9 is moved downwards, the second protection plate 14 can be rotated to block the sides of the drilling machine as well; when the second protection plate 14 is rotated to be parallel to the first protection plate 9 when not needed, the first protection plate 9 moves upwards to be inserted into the through groove 6 again.

The utility model has the advantages that: therefore, when the drilling machine works, a workpiece is firstly placed on the processing table 4, the driving motor 13 works at the moment, the driving motor 13 works to drive the gear 8 to rotate, and the gear 8 is meshed with the rack 10, so that the rack 10 can be driven to move downwards, the first protection plate 9 is moved downwards from the inside of the through groove 6 to block the front of the drilling machine, and scrap iron generated during drilling can be blocked by the first protection plate 9 in front, so that personal safety is protected; when the first protection plate 9 moves up and down in the through groove 6, the rack 10 on the first protection plate 9 cannot be derailed due to the sliding fit relationship between the dovetail slide bar 12 and the dovetail slide groove 11.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
