Description

A kind of gear sheet measuring for verticality jig

Technical field

The utility model relates to measuring for verticality technical fields, more particularly, to a kind of gear sheet measuring for verticality jig.

Background technique

Squareness measurement is to indicate that element to be measured keeps correct 90 ° of angle situations relative to reference element on part.? Orthogonal degree is kept between two elements being just known as.

In the prior art, measuring for verticality is measured by square mostly, but for some small parts, The error of measuring for verticality is larger, and gear sheet is made of columnar axis in blade, and the verticality for making it through square measurement is missed Difference is bigger, and structure is complicated for detection jig on the market, and cost is high, inconvenient for use, is not suitable for promoting and applying.

Therefore, it is necessary to provide the new technical solution of one kind to overcome drawbacks described above.

Utility model content

The purpose of this utility model is to provide the gear sheet measuring for verticality that one kind can effectively solve above-mentioned technical problem Jig.

For the purpose for reaching the utility model, adopt the following technical scheme that

A kind of gear sheet measuring for verticality jig, including pedestal, the channel being set on the pedestal are set to described lead to Through-hole, lower end on road lower surface are contained in the positioning pin in the through-hole, and detection slot, the inspection are additionally provided on the pedestal Surveying slot includes the upper and lower detection faces being parallel to each other, and the distance between described upper and lower detection faces are 0.95mm -1.1mm, described The roughness of upper and lower detection faces is Ra=0.2 μm.

Further: the side in the channel is mutually perpendicular to the upper and lower detection faces, the lower surface in the channel and institute Upper and lower detection faces are stated to be parallel to each other.

Further: the width in the channel is 12mm, and the distance of left and right surface to the workpiece end face in the channel is 0.2mm—0.5mm。

Further: the positioning pin is vertical with the lower surface in the channel.

Further: the pedestal is made of Cr12, and hardness is more than or equal to 58HRC after heat treatment.

Compared with prior art, the utility model has the following beneficial effects: the utility model gear sheet measuring for verticality Jig can carry out measuring for verticality to gear sheet, and the error of detection is small, and structure is simple, and easy to use, low cost is suitable for pushing away Wide application.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model gear sheet measuring for verticality jig.

Fig. 2 is the schematic diagram of the utility model gear sheet measuring for verticality jig detection slot and upper and lower detection faces.

Description of symbols: 1 is pedestal, and 2 be channel, and 3 be positioning pin, and 4 be detection slot, and 5 be upper and lower detection faces.

Specific embodiment

Clear and complete explanation is made to the utility model gear sheet measuring for verticality jig below in conjunction with attached drawing.

As shown in Figure 1 and Figure 2, a kind of gear sheet measuring for verticality jig, including pedestal 1 are set to logical on the pedestal Road 2, the through-hole being set on the channel lower surface, lower end are contained in the positioning pin 3 in the through-hole, also set on the pedestal It is equipped with detection slot 4, the detection slot includes the upper and lower detection faces 5 being parallel to each other.

As shown in Figure 1 and Figure 2, the distance between described upper and lower detection faces 5 are 0.95mm -1.1mm, vertical to guarantee The accuracy of detection is spent, the roughness of the upper and lower detection faces is Ra=0.2 μm, it thereby may be ensured that workpiece smoothly passes through, And workpiece will not be damaged.

As shown in Figure 1 and Figure 2, the side in the channel 2 is mutually perpendicular to the upper and lower detection faces 5, under the channel 2 Surface is parallel to each other with the upper and lower detection faces 5, to guarantee the accuracy of measuring for verticality.

As shown in Figure 1 and Figure 2, the width in the channel 2 is 12mm, the left and right surface in the channel 2 to workpiece end face away from From for 0.2mm -0.5mm, to guarantee that workpiece smoothly rotates in the channel 2.

As shown in Figure 1 and Figure 2, the positioning pin 3 is vertical with the lower surface in the channel 2, so as to prevent detection error Generation.

Further, the pedestal 1 is made of Cr12, and hardness is more than or equal to 58HRC after heat treatment, thereby may be ensured that The service life of the utility model, and can prevent the utility model from generating deformation, and then can guarantee the inspection of the utility model Survey precision.

It is practical below in conjunction with this in order to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model Point embodiment, rather than whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not being paid Every other embodiment obtained, belongs to the protection scope of the utility model under the premise of creative work.

Working principle:

First the lower end of the locating shaft 3 is inserted into the through-hole first, then covers gear sheet in described 3 upper end, Then product is rotated clockwise, so as to its detection Jing Guo the detection slot 4, when product does not connect with the upper and lower detection faces 5 The verticality of touching, i.e. expression product is qualified, on the contrary then unqualified.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
