The ejector lifting device resolves quality problems bearing accuracy damage and output shaft end face deformation and the like in prior assembly, and has the advantages of reliable work, reducing labor intensity, and being easy to manufacture.
Description
Technical field
The utility model relates to the workbench that a kind of cycloid speed reducer uses in assembling process, especially a kind of reductor fitter's bench push rod lowering or hoisting gear.
Background technology
In reductor product assembling process, during important spare parts such as assembling biaxial type reductor ring flange, pin wheel housing, Cycloidal Wheel, capacity eccentric bearing, following problem appears easily:
1, the power shaft end face is placed on the assembly work table top as support, and particularly because pin wheel housing and ring flange when press-fiting, pressure assembling force acts on the high-speed bearing, makes bearing accuracy impaired, causes product quality problems such as abnormal sound and heating to occur.
2, cycloidal-pin wheel power shaft support end facial disfigurement reduces the power shaft precision, is unfavorable for user installation.
3, in the cycloidal planetary gear speed reducer assembling process, casing is last, and is top-heavy, and workpiece is placed instability during assembling, and efficiency of assembling is low.
Summary of the invention
The utility model provides the reductor fitter's bench push rod that a kind of assembly quality is good, efficient is high lowering or hoisting gear for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of reductor fitter's bench push rod lowering or hoisting gear, comprise workbench, circumferentially be distributed on four vertical through hole on the workbench, be installed in four push rods of the pushing tow reductor ring flange in the workbench through hole, and the lowering or hoisting gear that drives each push rod, described lowering or hoisting gear is in each push rod lower end sliding bar to be installed, each sliding bar lower end connects a Moving plate that moves up and down, the Moving plate lower end is equipped with the uniform overhead cam that is shaped on three circle-arc teeth of end face, the workbench lower end is equipped with the price fixing concentric with Moving plate by fixed bar, the price fixing center is equipped with central shaft, the following cam that driven gear is installed on the central shaft and mates with overhead cam, the workbench lower end is vertically installed with decelerator, the decelerator upper end is an input, the output of decelerator lower end is equipped with driving gear, between driving gear and the driven gear idler gear that is meshed is installed.
Advantage and the good effect that the utlity model has are:
Because four push rods that move up and down that driven by decelerator, cam mechanism are installed on workbench, can hold up the reductor ring flange that is assembled, it is stressed to eliminate its output shaft, solve the bearing accuracy that exists in the former assembling and undermined quality problems such as output shaft face deformation, effectively improve product complete machine quality and assembling first-time qualification rate, improved operating efficiency; The utility model advantage of also having reliable operation, reducing labor intensity, be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the utility model jack-up assembly parts schematic diagrames.
Among the figure: 1, workbench; 2, fixed bar; 3, Moving plate; 4, overhead cam; 5, following cam; 6, driven gear; 7, price fixing; 8, push rod; 9, input; 10, sliding bar; 11, decelerator; 12, driving gear; 13, idler gear; 14, central shaft; 15, workpiece.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, workbench 1 is a flat board, circumferentially is evenly equipped with four vertical through hole on workbench, and four push rods 8 of pushing tow workpiece (reductor ring flange) 15 are installed in the workbench through hole.In each push rod lower end sliding bar 10 is installed, each sliding bar lower end connects a Moving plate that moves up and down 3, the Moving plate lower end is equipped with the uniform overhead cam 4 that is shaped on three circle-arc teeth of end face, the workbench lower end is equipped with the price fixing 7 concentric with Moving plate by fixed bar 2, the price fixing center is equipped with central shaft 14, the following cam 5 that driven gear 6 is installed on the central shaft and mates with overhead cam, as shown in Figure 2.The workbench lower end is vertically installed with decelerator 11, and decelerator upper end is an input 9, and the output of decelerator lower end is equipped with driving gear 12, between driving gear and the driven gear idler gear 13 that is meshed is installed.Like this, four push rods that move up and down by decelerator, cam mechanism drive can hold up the reductor ring flange that is assembled, and it is stressed to eliminate its output shaft, as shown in Figure 3.Solve the bearing accuracy that exists in the former assembling and undermined quality problems such as output shaft face deformation, effectively improved product complete machine quality and assembling first-time qualification rate, improved operating efficiency; The utility model advantage of also having reliable operation, reducing labor intensity, be easy to make in addition.
