Description

Aids for gear testing

technical field

The utility model relates to an auxiliary tool for gear detection, mainly relating to the field of idle wheel detection.

Background technique

A kind of idler gear is often used in the mechanical arm. The two ends of the gear are provided with journals. The two journals are the installation bearing positions. The distance A between the two journals is a specific dimension, which is the assembly dimension. If it is too long, the interference box cannot be installed, and if it is too short, the bearings will move in series after assembly. Therefore, the processed workpiece needs to be inspected in order to achieve the specified accuracy.

Some existing tools for detecting idler gears are to vertically fix a column on a workbench, fix a dial gauge on the upper end of the column, and set a fixing groove on the workbench at the same time, place the workpiece vertically, and the lower end of the workpiece The journal is installed in the fixed groove, the upper journal of the workpiece is in contact with the dial indicator, and the distance between the two journals can be judged by the change of the data of the dial indicator. This device has a big defect, because when the workpiece is installed on the detection device, the dial indicator needs to be moved to the other side in order to leave space for the workpiece installation, so the position of the dial indicator relative to the workbench will appear With multiple movements, the measurement error will increase, and the measurement efficiency will also be reduced.

Utility model content

Aiming at the above deficiencies in the prior art, the utility model proposes a fast and accurate detection aid for gear detection.

In order to achieve the above object, the technical solution of the present utility model is: comprising a workbench, a support frame, a dial indicator and a cap, a guide rail is arranged horizontally on the workbench, and a limit plate is slidably fitted on the guide rail, and the limit plate is vertically provided with Through holes, a support frame is provided on the workbench at one side of the guide rail, a dial indicator is provided on the support frame above the guide rail, a probe is provided on the dial indicator, and a cap is provided below the probe.

The technical principle of the utility model is as follows: when the workpiece is detected, the workpiece is first placed vertically, the limit plate slides to the side away from the support frame, and then the journal at the lower end of the workpiece is installed on the limit plate Fasten the cap on the journal of the upper end of the workpiece, slide the limit plate, so that the workpiece slides to the lower side of the dial indicator together with the limit plate, and the upper end of the cap contacts the probe. Finally, observe the data changes of the dial gauge.

The beneficial effects of the utility model are as follows: since the dial indicator has not moved during the whole detection process, that is to say, the relative position of the dial indicator and the workbench has not changed, all detected workpieces only need to be placed between the dial indicator and the workbench time, accurate detection can be obtained. At the same time, the process of installing the workpiece between the dial indicator and the worktable is realized through the sliding of the limit plate, so the installation speed is faster and the detection efficiency is further improved.

Further, the lower side of the guide rail is provided with chute side by side. If the journal of the workpiece is too long and the through hole of the limit plate is not enough to install the entire journal, the journal can be extended and placed in the chute.

Further, the support frame includes a column that is vertically slidably fitted on the workbench and a crossbeam horizontally arranged on the upper end of the upright. The end of the beam is fixed with a dial gauge, which is convenient for adjusting the relative position between the dial gauge and the workbench, so that the detection device The range of detected objects is larger.

Further, a roller is provided at the end of the probe to reduce the wear of the parts due to the friction generated when the probe and the cap move mutually.

Further, the upper end of the cap includes a horizontal plane in the middle part and inclined surfaces on both sides, and the setting of the inclined plane facilitates the detection by the probe on the horizontal plane in the middle part.

detailed description

The technical solutions in the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only preferred embodiments of the utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example

As shown in Fig. 1, the utility model comprises workbench 7, column 2, crossbeam 3 and dial gauge 1.

A guide rail is arranged horizontally on the workbench 7, and the limit plate 6 slides on the guide rail. The limit plate 6 is vertically provided with a through hole, and a chute is arranged side by side on the lower side of the guide rail. The chute is a longer journal. To provide a larger installation space, as shown in Figure 2, a column 2 is provided on the left side of the guide rail. The upper end of the column 2 is slidably fitted, and the crossbeam 3 extends to the right end, that is, above the guide rail, and a dial indicator 1 is fixed at the end of the crossbeam 3 .

On the lower side of the dial indicator 1 is the probe 101, and the lower side of the probe 101 is provided with a cap 4. When the workpiece 5 is installed, the lower end journal of the workpiece 5 is installed in the through hole of the limit plate 6, and the cap 4 is covered on the At the upper journal of the workpiece 5, as shown in Figure 3, a roller is provided at the lower end of the probe 101, which is more conducive to the sliding of the probe 101 to the upper end of the cap 4, and can reduce the loss caused by mutual friction to the parts. A horizontal plane is arranged in the middle of the cap 4, and inclined surfaces are provided on both sides of the horizontal plane, which is more convenient for the rollers to slide to the middle horizontal plane.
