Problems solved by technology

Because the outer surface precision and coaxiality of the outer surface of the gear box are not high, there will be a relatively large positioning error, which makes the axis of the detection motor and the axis of the gear box not well set on the same axis, which increases the rotation speed. Uncertainty of error and test results and risk of unreliability
[0004] In addition, because the gearbox inspection has three steps, which are run-in test, output end jump test and impact test, the traditional test needs to be completed through different tooling, which is a waste of time and labor costs

Embodiment 1

[0035] Such as figure 1 , 3 As shown, a gear box test tool for an electric tool includes a tooling platform 1, and the tooling platform 1 is respectively provided with a workpiece clamping mechanism and a runout detection mechanism.

[0036] Such as Figure 4-7 As shown, the workpiece clamping mechanism includes a positioning seat 11 fixed on the tooling table 1 by bolts, and the inner side of the middle part of the positioning seat 11 is provided with a workpiece mounting position for positioning the shaft core, and the workpiece mounting position is used for rapid positioning and clamping Artifact 2. The tail end of the workpiece 2 is provided with a positioning reference axis and a positioning reference plane. The workpiece mounting position is a mounting hole, on which a positioning flange 14 is fixed, and positioning pins 15 are arranged diagonally through pin holes on the positioning flange 14 . The positioning flange 14 is also provided with a positioning reference ...

Embodiment 2

[0046]The structure of the present invention is basically similar to Embodiment 1, the difference lies in the impact testing mechanism: the fixed seat 31 is movably arranged on the tooling table 1 through the ball screw feeding mechanism, and the wrench connecting rod 32 is directly fixed on the fixed seat 31, the structure that the guide block 35 and the fixed insert 37 jointly fix the wrench connecting rod 32 is replaced by the movement of the ball screw feed mechanism. In order to increase the stability of the fixing base 31 , the fixing base 31 can be fixed on the tooling table 1 by a pneumatic chuck. Before the workpiece is hit by the testing mechanism, the pneumatic chuck clamps the fixed seat 31 to start the hitting test work; when the test is finished, the pneumatic chuck is released, and the ball screw feeding mechanism moves to realize loading and unloading.

Abstract

The invention belongs to the technical field of detection equipment and particularly relates to a test tool of an electric tool speed reduction box. The test tool comprises a tool table, wherein a workpiece clamping mechanism and a jump detecting mechanism are respectively arranged on the tool table; the workpiece clamping mechanism comprises a positioning seat arranged on the tool table; a workpiece mounting site positioned by a shaft core is arranged on the inner side of the positioning seat; a test motor and a clamping power source used for driving workpieces to rotate are fixed on the outer side of the positioning seat; a telescopic rod of the clamping power source passes through the positioning seat and is subsequently fixed with a clamping jaw for clamping the workpieces; the jump detecting mechanism comprises a measuring bar mounted at a workpiece output end; a measuring meter and a mounting frame for mounting the measuring meter are arranged on the tool table at one side of themeasuring bar. Through the test tool of the electric tool speed reduction box, the workpieces can be rapidly and accurately positioned by a positioning pin; the clamping jaw is driven to rapidly clamp the workpieces through rotation of a rotating cylinder; the workpieces can be conveniently loaded and unloaded; the clamping time of the conventional test is greatly shortened; the detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, in particular to a test tool for a reduction box of an electric tool. Background technique [0002] An electric tool refers to a tool that is held and operated by hand, powered by a small-power motor or electromagnet, and driven by a transmission mechanism to drive the working head. It is characterized by light structure, small size, light weight, small vibration, low noise, flexible operation, easy to control and operate, easy to carry and use, strong and durable, can greatly reduce labor intensity, improve work efficiency, and realize manual operation. Mechanization. Therefore, it is widely used in construction, housing decoration, automobiles, machinery, electric power, bridges, gardening and other fields, and enters families in large quantities. [0003] The gearbox is the core structure of the electric tool. Therefore, it is necessary to test the product after it is assembled to ...
