Description
Technical Field
The utility model relates to a frock clamp technical field specifically is a tool is tested to the hole depth and the straightness in hole in work piece lateral wall processing hole.
Background
In the prior art, the hole depth inspection is mostly carried out by using a vernier caliper, and a standard measuring rod needs to be processed if the depth is larger than the deep hole within the measuring range of the vernier caliper, and whether the hole depth meets the precision requirement is determined by inserting the standard measuring rod into the hole. However, the above method can measure only the depth of the hole, and it is difficult to measure the straightness of the hole.
Because of the ideal state, the processing hole should be the cylindrical hole of perfect circle in cross-section, however in actual processing because of many-sided factors such as work piece clamp dress, drilling location, drill bit rig wearing and tearing, lead to the processing hole and be the cylindrical hole, but the error accords with the oval hole or the taper hole of design accuracy requirement, if insert downthehole inspection hole straightness with clearance fit's standard gauge rod, then easily take place dead problem of card when standard gauge rod does not reach hole ultimate depth position, lead to hole depth and hole straightness inspection to have the deviation, be difficult to reach inspection accuracy requirement.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a utensil is tested to the depth of hole and the straightness of hole in work piece lateral wall processing hole, should test the coaxial location of bellmouth with the drill way position to the inserted bar inspection hole depth and straightness of hole, can not take place the dead downthehole condition of inserted bar card, and simple structure, the suitability is strong.
A hole depth and hole straightness testing tool for a workpiece side wall processing hole comprises an insertion rod and a sleeve, wherein one end of the sleeve is coaxially inserted into a socket of the workpiece side wall processing hole, and the insertion rod is coaxially inserted into the sleeve in a sliding manner; one end of the inserted bar axially extends out of the sleeve, and the other end of the inserted bar is radially limited and axially connected with the side wall of the sleeve in a sliding fit manner.
And a socket with the diameter smaller than that of the outer ring of the sleeve is coaxially manufactured at one end of the sleeve, and a hanging hole is formed in the circumferential outer wall at the other end of the sleeve.
One end of the inserted rod penetrates through the socket and is coaxially inserted into the machining hole in the side wall of the workpiece, and the other end of the inserted rod is radially and symmetrically fixedly provided with a checking rod penetrating through the hanging hole; the test rod is guided by the inner wall of the hanging hole in a sliding way and is connected with the test rod in a limiting way along the axial maximum displacement.
The utility model has the advantages and the technical effects that:
the utility model discloses a hole depth and hole straightness testing tool for a workpiece side wall processing hole, which is inserted into a socket of the processing hole by a sleeve pipe to realize coaxial positioning of the sleeve pipe and the processing hole; judging whether the hole depth reaches the standard or not by using the sliding fit contact position of the checking rod and the hanging hole which are radially arranged at one end of the inserted rod, and finally checking the hole straightness by using the circumferential outer wall of one end, extending out of the sleeve, of the inserted rod, so that on one hand, the coaxiality of the inserted rod inserted into the processing hole is ensured by the sleeve, and the inserted rod is prevented from being clamped in the processing hole; on the other hand, the diameter of the inserted rod can be reduced, so that a gap in an enough error allowable range exists between the inserted rod and the hole wall, the straightness of the machined hole can be effectively checked, and the problem that the straightness of the hole is influenced by annular steps and the like on the inner hole wall when the machined hole is not formed at one time or is a discontinuous hole coaxially arranged on the inner hole wall can be checked.

Detailed Description
For a better understanding of the contents, features and effects of the present invention, the following embodiments will be illustrated in detail with reference to the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.
A hole depth and hole straightness testing tool for a workpiece side wall processing hole comprises an insertion rod 3 and a sleeve 1, wherein one end of the sleeve is coaxially inserted into a socket of a workpiece side wall processing hole 6, and the insertion rod is coaxially inserted into the sleeve in a sliding manner; one end of the inserted bar axially extends out of the sleeve, and the other end of the inserted bar is radially limited and axially connected with the side wall of the sleeve in a sliding fit manner.
And, the coaxial socket 2 that has the diameter to be less than the sleeve pipe outer lane diameter of making of sheathed tube one end, and seted up hanging hole 5 on the circumference outer wall of the sleeve pipe other end.
Moreover, one end of the inserted link penetrates through the socket and is coaxially inserted into the machining hole in the side wall of the workpiece, and the other end of the inserted link is radially and symmetrically fixedly provided with a checking rod 4 penetrating through the hanging hole; the test rod is guided by the inner wall of the hanging hole in a sliding way and is connected with the test rod in a limiting way along the axial maximum displacement.
To more clearly illustrate the embodiments of the present invention, an example is provided below:
the utility model discloses a hole depth and straightness of hole of work piece lateral wall processing hole test utensil, test during the inspection and have been by in supreme inserting as shown in figure 4 processing hole down, because the middle part of processing hole transversely pierces through there are other work piece holes, this work piece hole has been divided into two sections with the processing hole, so in order to inspect the axiality of two sections processing holes, avoid two hole situations that have the dislocation, so adopt hole depth and straightness in this application to test the utensil, sheathed tube socket inserts to inside the bellmouth of processing hole during inspection, with the assurance sleeve pipe, the axiality of intubate and processing hole, then push away and test the pole, and drive the inserted bar and slide to the processing hole is inside, up to inserted bar bottom shore in the processing hole, observe this moment and test whether the pole has reached the deepest of hanging hole, with this judges whether the hole depth meets the requirements.
Finally, the parts of the utility model which are not described adopt the mature products and the mature technical means in the prior art.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
