Description
Technical Field
The utility model relates to an adjusting device technical field specifically is a rack and pinion clearance adjustable device.
Background
The shearing blade sharpening machine is suitable for manufacturing and sharpening blades in the industries of wood processing, papermaking, printing, plastics, rubber, metallurgy rolled plates and the like, and at present, no factory adopts the structural type to be applied to equipment for grinding and sharpening the blades at home. Due to the fact that the linear guide rail pairs on domestic and foreign markets have different specifications in height and size, and the situation that gaps are too large may exist after the gears and the racks operate for a certain time, transmission efficiency is reduced and even the transmission efficiency is invalid.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a gear rack gap adjustable device.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a rack and pinion clearance adjustable device, includes the speed reducer, and the gear is fixed on the speed reducer output shaft, the speed reducer passes through the mounting panel to be fixed in frame one end, bolt fixedly connected with slider is passed through to the right side bottom of frame, and the bottom embedding of slider is provided with linear guide, and linear guide parallel mount in lathe right side top, the rack is installed in lathe one side, the embedding sets up adjusting shim between speed reducer and the mounting panel.
Preferably, the machine tool, the linear guide rail and the frame are parallel to each other, and the sliding block slides left and right along the linear guide rail.
Preferably, the gear and the rack are engaged with each other.
Preferably, the mounting plate is L-shaped, and the mounting plate is at a 90-degree right angle.
Preferably, the speed reducer includes an electric motor therein.
The utility model provides a gear rack clearance is adjustable device. The method has the following beneficial effects: the gear rack gap adjustable device achieves the installation requirement of being adaptive to the difference of the height and the size of the linear guide rail, and the adjustment gasket is ground and properly thinned to achieve the purpose of eliminating the gap between the gear and the rack, so that the gear rack gap adjustable device can be used for grinding equipment of most long straight-edge cutter cutting edges and is used for a gear and rack transmission device which vertically walks.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of a part of an enlarged structure of fig. 1 according to the present invention.
In the figure: 1. a gear; 2. a rack; 3. a speed reducer; 4. a slider; 5. mounting a plate; 6. adjusting the gasket; 7. a machine tool; 8. a linear guide rail; 9. a vehicle frame.
Detailed Description
As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a rack and pinion clearance adjustable device, includes speed reducer 3, and gear 1 fixes on 3 output shafts of speed reducer, and speed reducer 3 passes through mounting panel 5 to be fixed in frame 9 one end, and bolt fixedly connected with slider 4 is passed through to the right side bottom of frame 9, and the bottom embedding of slider 4 is provided with linear guide 8, and linear guide 8 parallel mount in 7 right side tops of lathe, and rack 2 installs in 7 one sides of lathe, and the embedding sets up adjusting shim 6 between speed reducer 3 and the mounting panel 5.
Preferably, lathe 7, linear guide 8 and frame 9 are parallel to each other, and slider 4 slides along linear guide 8 from side to side, better reference adjustment when being convenient for later stage to have the condition of different specifications on the linear guide 8 height dimension to reduce the clearance between gear and the rack.
Preferably, the gear 1 and the rack 2 are engaged with each other, so that the gear 1 and the rack 2 are driven by the speed reducer 3, and the left-right sliding of the frame 9 is realized.
Preferably, the mounting plate 5 is L-shaped, and the mounting plate 5 is at a right angle of 90 degrees, so that when the adjusting gear and the rack are not easy to deviate, the gap between the gear and the rack can be adjusted more accurately.
Preferably, the reduction gear 3 includes a motor therein to effectively provide a driving force.
When in use, firstly, the speed reducer 3 is electrically connected with an applicable power supply through a built-in power line, the speed reducer 3 is internally provided with a motor, the motor drives the speed reducer 3, an output shaft of the speed reducer 3 drives the gear 1 and transmits the gear to the rack 2, at the moment, the slide block 4 at the lower end of the frame 9 slides left and right along the linear guide rail 8, meanwhile, due to the fact that conditions with different specifications exist on the height dimension of the linear guide rail 8 in domestic and foreign markets, the adjusting gasket 6 is arranged between the speed reducer 3 and the mounting plate 5, the mounting requirements which are not suitable for the height dimension of the linear guide rail 8 are met through adjusting the thickness of the adjusting gasket 6, when the gear 1 and the rack 2 run for a certain time, the condition that the gap is too large possibly exists, the transmission efficiency is reduced, even the gap between the gear and the rack is failed, at the time, the whole process is completed.
