Description

Technical Field

[0001] The utility model relates to the technical field of detecting the position length size of a workpiece, in particular to a length measurement auxiliary device, which is suitable for measuring the position size of a workpiece which cannot be measured by an existing readable gauge. Background Art

[0002] Currently, readable length measuring fixtures are suitable for measuring planes and large spatial locations. They are limited in the dimensions of three-dimensional dimensions and narrow spatial locations and cannot be accurately measured. They can only be measured using three-coordinate measuring equipment. The measurement cost is high and the measurement time is long, which is time-consuming and labor-intensive, and the measurement efficiency is low. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a length measurement auxiliary device, which mainly solves the measurement problem that the existing readable gauge cannot measure the position size.

[0004] The technical solution provided by the utility model is: a length measurement auxiliary device, which is special in that it consists of a measuring rod, a movable measuring ruler, a fastening screw, a guide pin, a blocking block, and a fixed measuring ruler; a fixed measuring ruler is arranged at one end of the measuring rod, and a movable measuring ruler is installed at the other end of the measuring rod through a screw; a hole is arranged at the top end of the movable measuring ruler, a guide pin is arranged in the hole of the movable measuring ruler, and the movable measuring ruler moves on the measuring rod; and a blocking block is arranged at the end of the measuring rod at the outer end of the movable measuring ruler.

[0005] Furthermore, one end of the measuring rod is interference-fitted with a fixed measuring ruler.

[0006] Furthermore, a keyway for guiding is arranged on the measuring rod, and a movable measuring ruler is arranged on the measuring rod with the keyway, and the movable measuring ruler moves along the keyway on the measuring rod.

[0007] The beneficial effects of the utility model are as follows: 1. The fixed measuring ruler and the movable measuring ruler are used in combination, which saves effort in measurement and reduces the labor intensity of the operator; 2. It can be used for auxiliary measurement of dimensions at different positions, with short measurement time and low measurement cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a schematic diagram of the use state of the utility model.

[0010] In the figure: 1. measuring rod, 2. movable measuring ruler, 3. fastening screw, 4. guide pin, 5. blocking block, 6. fixed measuring ruler. DETAILED DESCRIPTION

[0011] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, a length measurement auxiliary device is composed of a measuring rod 1, a movable measuring ruler 2, a fastening screw 3, a guide pin 4, a block 5, and a fixed measuring ruler 6; the fixed measuring ruler 6 is installed at one end of the measuring rod 1 with interference fit to ensure that the fixed measuring ruler 6 does not fall off or loosen; after the fastening screw 3 is installed on the movable measuring ruler 2, the movable measuring ruler 2 is installed on the other end of the measuring rod 1, and the other end of the measuring rod 1 is provided with a keyway for guiding, and the movable measuring ruler 2 moves along the keyway on the measuring rod 1; a hole is opened at the top end of the movable measuring ruler 2, and the guide pin 4 is installed in the hole of the movable measuring ruler 2 to ensure that the movable measuring ruler 2 moves on the measuring rod 1 according to a specified trajectory and does not rotate; finally, the block 5 is installed at the end of the measuring rod 1 at the outer end of the movable measuring ruler 2 to prevent the movable measuring ruler 2 from falling off.

[0013] The utility model provides a length measurement auxiliary device, and the specific use steps are as follows: Figure 2 , install the above-mentioned auxiliary device at both ends of the workpiece position size, position the fixed measuring ruler 6 at one end of the workpiece to be measured, slide the movable measuring ruler 2 to the other end of the workpiece to be measured, ensure that it is completely close to the workpiece, use the fastening screw 3 to fasten the movable measuring ruler 2, remove the auxiliary device, and use a readable gauge to detect the length between the fixed measuring ruler 6 and the movable measuring ruler 2, which can truly reflect the size of the workpiece at this point.

[0014] It should be understood that the technical features not elaborated in this specification belong to the prior art. Although the implementation methods of the utility model patent are described above in conjunction with the drawings, the utility model is not limited to the above specific implementation methods, which are only illustrative and not restrictive. Ordinary technicians in this field can make more forms under the enlightenment of the utility model without departing from the scope of protection of the purpose of the utility model and the claims, which are all within the protection scope of the utility model.
