Description

Technical Field

[0001] This application relates to the technical field of lawnmower wheel and axle manufacturing, and in particular to a drilling device for machining oil injection holes in lawnmower wheel and axle housings. Background Technology

[0002] like Figure 1 The lawnmower axle 9 shown requires an oil injection hole 91 to be machined on the side of the axle housing during the production process. The oil injection hole is inclined. When drilling, the axle housing needs to be tilted and fixed on the fixture. The fixture currently used is generally a bench vise. The operator needs to accurately tilt and clamp the axle housing in the bench vise. The clamping efficiency is low and it is easy to damage the axle housing. At the same time, the bench vise can only clamp one workpiece at a time. After drilling, it takes a lot of time to replace the axle housing.

[0003] Therefore, there is an urgent need to develop a high-efficiency drilling device. Utility Model Content

[0004] The purpose of this application is to provide a drilling device for machining oil injection holes in the wheel axle housing of a lawnmower, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a drilling device for machining oil injection holes in lawnmower wheel axle housings, employing the following technical solution:

[0006] A drilling device for machining oil injection holes in a lawnmower axle housing includes a workbench and a drilling machine disposed beside the workbench. The workbench also includes a feeding mechanism comprising a divider, a turntable, a reduction motor, and clamping components. The divider and the reduction motor are both mounted on the bottom of the workbench, with the reduction motor connected to the divider. The turntable is rotatably mounted on the top of the workbench and connected to the output shaft of the divider. Four clamping components are evenly distributed on the surface of the turntable. Each clamping component includes a base, a rotating base, and a vertical quick-clamping clamp. A push-pull quick clamp and a wedge block are provided. The base is fixed on the workbench. An inclined arc-shaped groove is provided on one side of the base. A rotating seat is rotatably connected to the base. A mounting part is provided in the middle of the rotating seat. A clearance groove is provided in the middle of the mounting part. Positioning rods are fixed at the four corners of the top of the mounting part. Vertical quick clamps are symmetrically fixed on both sides of the mounting part. The push-pull quick clamp is fixed on the workbench. The wedge block is fixed at the end of the push-pull quick clamp. The wedge block is set in the base and is perpendicular to the rotating seat.

[0007] Preferably, a cover is fixed to the side of the base, and a coil spring is provided inside the cover. One side of the rotating seat is disposed inside the cover and connected to the coil spring. The coil spring can drive the rotating seat to reset.

[0008] By adopting the above technical solution, the coil spring can drive the rotating seat to reset, which greatly facilitates the loading of materials by the staff.

[0009] A protective pad is provided inside the arc-shaped groove.

[0010] The base has several chip removal grooves on its side.

[0011] Preferably, a stop block is provided on one inner wall of the base of the wedge-shaped block, and the mounting part can be placed flat on the stop block.

[0012] By adopting the above technical solution and by setting a stop block, the rotating seat can be horizontally stopped on the stop block under the reset action of the coil spring, which facilitates the loading and unloading of materials by the staff.

[0013] Preferably, the workbench has an upward-curving edge on its periphery, and a drain outlet is provided on one side of the edge.

[0014] By adopting the above technical solution, the folded edge can form a pool on the surface of the workbench, which can guide the cutting fluid to drain away and avoid affecting the loading and unloading of materials by the workers.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. The drilling device for processing the oil injection hole of the lawnmower wheel axle housing is equipped with a divider and a turntable. The turntable is equipped with four clamping components. The operator only needs to load and unload the material in one position. The divider drives the turntable to rotate, which can realize continuous drilling by the drilling machine, greatly improving production efficiency.

[0017] 2. The clamping assembly has a clever structural design, is easy to use, and has a good clamping effect. The operator places the lawnmower wheel axle housing into the positioning rod and presses it with the vertical quick clamps on both sides. Then, push the lawnmower wheel axle housing to tilt it against the arc groove and push the push-pull quick clamp to make the wedge block abut against the mounting part, so that the lawnmower wheel axle housing can be fixed in an inclined position.

The turntable 4 is rotatably mounted on the top of the workbench 1 and is connected to the output shaft of the divider 3. Four clamping components 6 are evenly distributed on the surface of the turntable 4. Each clamping component 6 includes a base 61, a rotating seat 62, a vertical quick clamp 63, a push-pull quick clamp 64, and a wedge block 65. The base 61 is fixed to... On the workbench 1, an inclined arc-shaped groove 611 is provided on one side of the base 61, and a protective pad is provided in the arc-shaped groove 611. The rotating seat 62 is rotatably connected to the base 61. The rotating seat 62 is provided with a mounting part 621 in the middle, and a clearance groove 6211 is provided in the middle of the mounting part 621.
