Description

Constant Velocity Universal Joint Drive Shaft Assembly Measuring Workbench

technical field

The invention relates to a constant velocity universal joint drive shaft assembly, and can also be used in other fields of mechanical design, manufacture and processing, in particular to a constant velocity universal joint drive shaft assembly measuring workbench.

Background technique

The constant velocity universal joint drive shaft assembly is a key component in the drive system of a small car. It is composed of a fixed end ball cage type constant velocity universal joint and a sliding end ball cage type constant velocity universal joint that can move axially. , both ends are equipped with elastic rubber dust cover, fixed end ball cage type constant velocity universal joint has involute flower and thread, and sliding end mobile constant velocity universal joint has involute spline and smooth cylindrical journals. At present, the constant velocity universal joint drive shaft assembly needs to measure the compressed length, spline ring gauge set inspection, thread gauge set inspection, sleeve gauge set inspection for smooth journal hole, and the required ring gauge, etc. There are many sets of gauges. When using a conventional workbench for measurement work, many ring gauges and sets of gauges will be confused, there is no place to place them, or the placement is messy and difficult to find. At the same time, there are many types of assemblies, and the compression length and size are different. It is very large, and using simple calipers will cause inaccurate measurements, and the compression also requires another person to assist. Low work efficiency and high labor intensity. Using the present invention, the ring gauges and sets of gauges can be hung on the wall board according to the category, which is very convenient to take. At the same time, the ball screw compression assembly can be manually rotated and the length can be accurately read from the scale on the wall of the measuring tank. The measurement time is shortened.

Contents of the invention

The present invention provides a method for overcoming the problems of low working efficiency, no place for orderly placement of sleeve gauges, measuring tools and tools, and inconvenient and inaccurate measurement of compression length in order to overcome the existing constant velocity universal joint drive shaft assembly. A new type of measuring bench.

The present invention solves technical problem and provides following scheme:

A constant velocity universal joint drive shaft assembly measuring platform, including a workbench 1, the worktable of the workbench 1 is provided with a length measurement "V" groove 2, and the worktable of the workbench 1 is A backing plate 3 is fixed, a support block 4 is fixed on the backing plate 3, a ball nut cover 7 is fixed on the support block 4, a ball screw 6 is fitted inside the ball nut cover 7, and a hand wheel 5 is connected to the right end of the ball screw 6 , the left end of the ball screw 6 is provided with an axially movable pressure plate 8, and the axially movable pressure plate 8 is fixed in the end groove of the ball screw 6 through the fixed pin 9, and the axially movable pressure plate 8 and the ball screw 6 are lined with The plane bearing 10, the front and rear of the workbench machine 1 has a vertical wall plate 15, and a plurality of studs 11 are distributed on the wall plate 15.

A total of 121 studs 11 in 6 rows and 21 columns are arranged on the wall plate, and nuts 12 are provided at the ends of the studs 11 . There is a baffle plate 14 at the left end of the "V" groove 2 for measuring the compressed length.

A compressed length measuring groove is provided on the measuring workbench to measure the compressed length of the assembly; a scale is provided on the side wall of the compressed length measuring groove to obtain the measured size, and a shaft is arranged in the measuring groove The axially moving pressure plate can be driven by the ball screw to move axially left and right on the scale of the measuring groove to obtain the specific measurement size. The ball screw is installed in the ball nut sleeve, and the handwheel can be turned by hand It rotates with action and converts the rotary motion into linear movement; the wall plate of the measuring workbench hanging inspection gauge has a stud with a nut at the end, which can be used to hang a circular spline sleeve and a ring gauge with a round hole. The end nut prevents the spline sleeve and the round hole ring gauge from slipping out; there are three tool cabinets under the workbench, which can store commonly used measuring tools and tools and can be placed in categories. .

The workbench frame of the present invention is the main body that carries the entire measuring workbench, and the wall plate erected in front of its worktable is provided with six rows and 21 columns with a total of 121 studs with nuts at the ends for hanging flowers. Key ring gauges, threaded ring gauges, ring gauges for smooth holes and other sets of gauges, and the nuts at the ends of the studs prevent the sets of gauges from slipping; the working table is also equipped with a "V"-shaped compression length measurement of stainless steel sheet bending Slot, the scale size is set on the front side wall of the measuring groove, and at the same time, there is an axially moving pressure plate in the "V" groove, and the axially moving pressure plate is stuck in the groove on the ball screw through the pin in the inner hole to achieve the ball screw. The rotational movement of the rotary motion is converted into left and right movement, and the size of the measured assembly is read by axially moving the scale value corresponding to the position of the pressure plate on the scale; the ball screw is connected with a ball nut sleeve, and the ball nut sleeve is fixed on the support by screws. On the block, the support block is fixed on the backing plate by screws, and the backing plate is fastened on the worktable by four bolts; the ball screw is rotated by hand to rotate the hand wheel at the end of the ball screw and drives the axial movement of the pressure plate to measure "V "Move left and right on the groove scale to compress the constant velocity universal joint drive shaft assembly, and read the measured size from the position on the scale where the axially moving pressure plate is located. The purpose of axially moving the plane bearing behind the pressure plate is to reduce the friction between the ball screw and the end face of the pressure plate when the ball screw rotates.

The beneficial effects of the present invention are:

1. It can quickly and accurately measure the dimensions of the constant velocity universal joint drive shaft assembly in all directions;

2. Be able to quickly find all kinds of gauges needed in the measurement process;

3. It can ensure fast and easy effective compression of the constant velocity universal joint drive shaft assembly to ensure that the compression is in place;

4. Reduce the labor intensity of surveyors and improve work efficiency;

5. Inspection, measuring tools and tools are placed in an orderly manner, which improves the environment of the workplace.
