Abstract
The utility model provides a drum type tool magazine. Tool chambers are arranged in a rolling wheel of the drum type tool magazine, a shaft hole in the axial direction is formed in the center of the rolling wheel, a rolling wheel support is provided with a shaft which penetrates through the shaft hole to be connected with the rolling wheel, a second spring perpendicular to the axial direction is arranged on the shaft, the two ends of the second spring are connected with second balls respectively, clamping grooves corresponding to the tool chambers in number are formed in the periphery of the shaft hole, and the second balls are matched with the clamping grooves. According to the drum type tool magazine, in each time of rotation, the balls at the two ends of the spring rotate to the corresponding clamping grooves, the rolling wheel rotates by a fixed angle in each time of rotation, and due to the structure comprising the balls and the clamping grooves, the drum type tool magazine is simple in structure, low in cost and flexible and accurate in rotation.
Description
Technical field
The utility model relates to a kind of electric tool technical field, is specifically a kind of drum-type tool magazine for electric tool.
Background technology
Publication number is that the Chinese patent application of CN101563192 discloses a kind of electric tool with drum-type tool magazine.This electric tool has pistol-shaped casing, and there is the upwardly extending main shaft in gun barrel side, electric tool output shaft is in the exit of gun barrel direction, it is a cutter dop, motor is housed in casing, drum-type tool magazine and transmission device, drum-type tool magazine is cylindrical structure, the axis of the axis of drum-type tool magazine and cutter dop is parallel to main shaft, drum-type tool magazine annular on self is provided with the cutter chamber parallel with main shaft, these cutter chambers occupy according to the position of rotation of drum-type tool magazine the lap position aligning with cutter dop respectively, in this lap position, corresponding cutter can shift between cutter chamber and cutter dop, described transfer is passed through in coaxial with cutter dop, the executing agency of the operation saddle form being led in hull outside realizes.Drum-type tool magazine is formed on housing equally, and by the power transmission shaft of transmission device, run through in the central area that drum-type tool magazine is surrounded by cutter chamber, turning cylinder passes this tool magazine and is connected with cutter dop drive-type by gear, can be with cutter dop to rotate.
But this center due to this electric tool intermediate roll formula tool magazine will be transmitted axle, run through, therefore the rotational structure of drum-type tool magazine self is provided in a side of outside its center, complicated structure.
Utility model content
Technical problem to be solved in the utility model is, overcome the defect of prior art, and a kind of drum-type tool magazine simple in structure is provided.
For solving the problems of the technologies described above, the utility model proposes a kind of drum-type tool magazine, it comprises roller, rolling wheel support, in described roller, be provided with cutter chamber, the center of described roller is provided with axial axis hole, described rolling wheel support is provided with axle and is connected with roller through axis hole, described axle is provided with the spring perpendicular to axis direction, the two ends of described spring are all connected with ball, the circumference of described axis hole is provided with the draw-in groove corresponding with the quantity of cutter chamber, described ball coordinates the bottom surface of described draw-in groove with draw-in groove be cambered surface, for accommodating ball.On rolling wheel support during rotation roller, can be by the cooperation of draw-in groove and ball, make to rotate the fixing angle of equal transmission, so that the cutter in the tool magazine of each turned position is all just corresponding with cutter dop at every turn, there will not be deviation, make cutter discrepancy tool magazine all very smooth and easy.
Adopt after said structure, the utlity model has following advantage: the form that the utility model adopts draw-in groove and ball to coordinate, the corresponding draw-in groove in each cutter chamber, when roller rotates on rolling wheel support, while rotating, ball all snaps in a draw-in groove at every turn, while making to rotate at every turn, can both rotate fixed angle, make no matter while turning to any angle, have a cutter chamber in electric tool in the position that aligns of cutter dop.And convenience simple in structure.
The cross section of the bottom surface of described draw-in groove is arc.Adopt this structure, the bottom surface of arc can coordinate ball better, when roller rotates with respect to rolling wheel support, makes to rotate more flexibly accurately.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of roller and rolling wheel support;
Fig. 2 is the cross-sectional schematic that roller and rolling wheel support are installed.
As shown in the figure: 5, drum-type tool magazine, 5.1, roller, 5.2, rolling wheel support, 5.5, cutter chamber, 5.6, axis hole, 5.7, axle, 5.8, spring, 5.9, ball, 5.10, draw-in groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1-2: the utility model provides a kind of drum-type tool magazine 5, it comprises roller 5.1, rolling wheel support 5.2, in the roller 5.1 of described drum-type tool magazine 5, be provided with cutter chamber 5.5, described roller 5.1 center is provided with axial axis hole 5.6, described rolling wheel support 5.2 is provided with axle 5.7 and is connected with roller 5.1 through axis hole 5.6, 5.7 springs 5.8 that are provided with perpendicular to axis direction on described axle, the two ends of described spring 5.8 are all connected with ball 5.9, the circumference of described axis hole 5.7 is provided with the draw-in groove corresponding with the quantity of cutter chamber 5.5 5.10, described ball 5.9 coordinates with draw-in groove 5.10.The bottom surface of described draw-in groove 5.10 is cambered surface, for accommodating ball.On rolling wheel support during rotation roller, can be by the cooperation of draw-in groove and ball, make to rotate the fixing angle of equal transmission, so that the cutter in the tool magazine of each turned position is all just corresponding with cutter dop at every turn, there will not be deviation, make cutter discrepancy tool magazine all very smooth and easy.
Due to the effect of spring and ball, while rotating, the ball of both ends of the spring all can forward in corresponding draw-in groove at every turn, each roller is rotated and can rotate fixed angle, and owing to just adopting the structure of ball and draw-in groove, relatively simple for structure, cost is lower, and rotates flexibly, accurately.
The cross section of the bottom surface of described draw-in groove 5.10 is arc.Adopt this structure, the bottom surface of arc can coordinate ball better, when roller rotates with respect to rolling wheel support, makes to rotate more flexibly accurately.
