Abstract
The utility model disclose it is a kind of for and meanwhile examine the cubing of tooth form and keyway, which is characterized in that examine block, lower tolerance that block and mounting rod, the bottom end of the mounting rod is examined to be threadingly attached to bottom plate including upper tolerance；The side of the mounting rod is equipped with the key of Z-direction.Two inspection module integrations can be assembled once when examining and complete two-part inspection by a set of instruments of inspection.
Description
Technical field
The utility model belongs to the technical field of the instruments of inspection, is specifically related to one kind and is used for while examining tooth form and keyway
Cubing.
Background technique
The high-volume instruments of inspection of the form of gear tooth at present, mostly individually customization tooth form examines block, and inspection block is put into tooth to be checked
In wheel, both observations degree of engagement judges whether the form of gear tooth is qualified.When general high-volume examines the form of gear tooth, customization is used
Two inspection blocks of worst error and minimal error are put into gear, see the cooperation situation of two inspections blocks and product.Product batch is larger
When, inspection block cooperation takes out difficulty when slightly tight, and replacement causes checkability low back and forth.
The a part of gear as transmission mechanism, the most common mounting means is exactly axis hole connection fit keyway, and keyway
Excessive or tooth form is unqualified, and the influence to transmission accuracy and efficiency can be very big.We are with a set of instruments of inspection support rod, cooperation
Block is examined in different customizations, has accomplished the inspection block integration of upper tolerance and lower tolerance；The tolerance of keyway is detected when detecting tooth form one
And measure, accomplish the superposition of dimension chain, has eliminated tooth form and keyway and all meet the requirements but whole ungratified possibility；
Utility model content
The use of the new type is to solve technical problem present in above-mentioned background technique, a set of instruments of inspection is provided, by two
Inspection module integration.
The utility model uses following technical scheme: a kind of for examining the cubing of tooth form and keyway, including upper public affairs simultaneously
Difference examines block, lower tolerance that block and mounting rod, the bottom end of the mounting rod is examined to be threadingly attached to bottom plate；The mounting rod
Side is equipped with the key of Z-direction；The upper tolerance examines the tooth footpath inside block to be greater than the tooth footpath that the lower tolerance examines block；It is described
It is the maximum limit of gear that upper tolerance, which examines the tooth footpath inside block,；The lower tolerance examine the tooth footpath inside block be gear most
Small limiting value.
Further, the bottom plate is uniformly distributed there are four waist through hole around the center of circle.
Further, the upper tolerance examines block and the lower tolerance to examine and be bolted to connection between block.
Further, the lower tolerance examines block and bottom plate to be bolted to connection.
Further, the key is the keyway for examining gear to be detected.
The utility model has the beneficial effects that a set of instruments of inspection, by two inspection module integrations, the energy one when examining
Two-part inspection is completed in secondary assembly；It solves the problems, such as gear size chain, avoids the product comprehensive judgement of multiple qualified sizes
Underproof situation；Multiple tooth forms can be customized on each inspection block, a set of cubing can satisfy the inspection demand of a variety of tooth forms, nothing
Cubing need to be customized for every kind of tooth form.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the bottom view of the utility model.
Each mark of Fig. 1 to Fig. 2 are as follows: tolerance examines block, 2 lower tolerances to examine block, 3 mounting rods, 4 bottom plates, 5 kidney-shapeds logical on 1
Hole, 6 gears to be detected, 7 keys.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of for examining the cubing of tooth form and keyway simultaneously, including upper tolerance examine block 1, under
Tolerance examines block 2 and mounting rod 3, the bottom end of the mounting rod 3 to be threadingly attached to bottom plate 4；The side of the mounting rod 3 is set
There is the key 7 of Z-direction.The key 7 is the keyway for examining gear 6 to be detected.
The upper tolerance examines block 1 and the lower tolerance to examine and be bolted to connection between block 2.The lower tolerance inspection
It tests block 2 and bottom plate 4 is bolted to connection.
The upper tolerance examines the tooth footpath inside block 1 to be greater than the tooth footpath that the lower tolerance examines block 2.The upper tolerance is examined
Tooth footpath inside block 1 is the maximum limit of gear.It is the least limit of gear that the lower tolerance, which examines the tooth footpath inside block 2,
Value.
The bottom plate 4 is uniformly distributed there are four waist through hole 5 around the center of circle.
When inspection, by geared sleeve to be checked on mounting rod, if being not placed into, hole or keyway on gear are less than lower public affairs
Difference, it is unqualified；If can be put into, it will move on to above cubing template, due to there is gap between keyway both sides and key, therefore be able to rotate to be checked
Gear is rotated to the left and is rotated to the right when can be put into tooth form tolerance and examining block, it was demonstrated that tooth form is less than tolerance, width of keyway
Without departing from upper tolerance；Adjust the angle, trial is loaded under tooth form tolerance and examines block, if can be put into, tooth form be less than under tooth form
Tolerance.
Judged whether it is qualified after, ejected upwards in your four waist round hole of finger from below, dismantle very convenient, improved
Checkability.
Claims (5)
1. a kind of for examining the cubing of tooth form and keyway simultaneously, which is characterized in that examine block, lower tolerance to examine including upper tolerance
