Abstract
The utility model discloses a camshaft half-round key installation height detection tool, which comprises a detection sleeve (1), wherein the detection sleeve (1) is provided with a conical through hole (11), the conical through hole (11) is matched with a camshaft (3) to be detected, the inner wall of the conical through hole (11) is provided with a chute (12), the included angle between the bottom surface of the chute (12) and the axis of the conical through hole (11) is equal to half of the cone angle of the conical through hole (11), the height of the chute (12) is equal to the maximum allowable height of a half-round key (2) to be detected, which is installed on the camshaft (3), and the width of the chute (12) is matched with the width of the half-round key (2). If the detection sleeve (1) can not be completely sleeved and attached to the semicircular key (2), the semicircular key (2) is excessively high in installation and needs to be adjusted and assembled again, so that the semicircular key (2) is ensured not to be ultrahigh, and the situation that subsequent parts cannot be installed during assembly of the cam is avoided.
Description
Technical Field
The utility model relates to a camshaft half-round key installation height detection tool.
Background
The assembly of parts is related to various modern industrial products such as automobiles, ships and the like, wherein a cam shaft semicircular key part is a common connecting part, the semicircular key is one type of key, the upper surface of the cam shaft semicircular key part is a plane, the lower surface of the cam shaft semicircular key part is a semicircular cambered surface, the two side surfaces of the cam shaft semicircular key part are parallel, and the mounting mode is to directly knock into a key slot, but if the semicircular key part is slightly higher, the cam shaft semicircular key part cannot be seen by naked eyes, so that the subsequent assembly is affected.
Disclosure of Invention
In order to solve the problem that the following assembly is affected due to the fact that after a semicircular key is knocked into a key groove, the semicircular key is slightly high and cannot be seen by naked eyes in the prior art, the utility model provides a camshaft semicircular key installation height detection tool. The utility model discloses a camshaft half-round key installation height detection tool which is characterized by comprising a detection sleeve, wherein the detection sleeve is provided with a conical through hole, the conical through hole is matched with a camshaft to be detected, the inner wall of the conical through hole is provided with a chute, the included angle between the bottom surface of the chute and the axis of the conical through hole is equal to half of the angle of the conical through hole, the height of the chute is equal to the maximum allowable height of a half-round key to be detected, which is installed on the camshaft, and the width of the chute is matched with the width of the half-round key.
Further, the thickness of the detection sleeve is larger than the length of the semicircular key.
Further, the detecting sleeve is made into a cylindrical shape, and reticulation is formed on the outer surface of the cylindrical shape.
Compared with the prior art, the utility model has the following advantages:
the utility model provides a camshaft half key installation height detection tool, which is characterized in that when the camshaft half key installation height detection tool is used, after a half key is assembled on a camshaft, a detection sleeve is sleeved into the camshaft, a chute of the detection sleeve is sleeved into the half key, if the detection sleeve can be completely sleeved and attached to the half key, the half key is not higher than the installation requirement, if the detection sleeve cannot be completely sleeved and attached to the half key, the half key is excessively high, the installation of the half key is required to be adjusted and assembled again, so that the half key cannot be ultrahigh, and the condition that the installation cannot be performed when follow-up parts such as a cam are assembled is avoided.
Drawings
Fig. 1 is a schematic view of a camshaft half key mounting height detection tool of the present utility model.
Fig. 2 is a schematic left-hand view of fig. 1.
Fig. 3 is a schematic diagram of a detection use of a camshaft half key mounting height detection tool of the present utility model.
In the figure, 1, a detection sleeve, 2, a semicircular key, 3, a cam shaft, 11, a conical through hole and 12, a chute.
Detailed Description
The present utility model will be described in further detail with reference to examples, but embodiments of the present utility model are not limited thereto.
Fig. 1 and 2 show an embodiment of a tool for detecting the mounting height of a cam shaft semicircular key according to the present utility model, which is characterized by comprising a detecting sleeve 1, wherein the detecting sleeve 1 is provided with a conical through hole 11, the conical through hole 11 is adapted to a cam shaft 3 to be detected, the inner wall of the conical through hole 11 is provided with a chute 12, the included angle between the bottom surface of the chute 12 and the axis of the conical through hole 11 is equal to half of the angle of the conical through hole 11, the height of the chute 12 is equal to the maximum allowable height of a semicircular key 2 to be detected mounted on the cam shaft 3, and the width of the chute 12 is adapted to the width of the semicircular key 2.
The thickness of the detection sleeve 1 is larger than the length of the semicircular key 2. Thus, whether the detecting sleeve 1 can be completely sleeved and attached to the semicircular key can be more intuitively observed.
The detecting sleeve 1 is cylindrical in shape, and reticulation is formed on the outer surface of the cylindrical shape. In this way, the detection sleeve 1 is stable in detection.
Claims (3)
1. A camshaft semicircle key mounting height detection instrument, its characterized in that: including detecting cover (1), detection cover (1) open and to have circular cone through-hole (11), circular cone through-hole (11) with wait to detect camshaft (3) phase, circular cone through-hole (11) inner wall open and to have chute (12), chute (12) bottom surface with the contained angle of circular cone through-hole (11) axis with the cone angle of circular cone through-hole (11) half equal, the height of chute (12) with camshaft (3) on the maximum allowable height of the semicircular key (2) that awaits measuring of installation equal, the width of chute (12) with the width of semicircular key (2) phase.
2. The camshaft half key mounting height detection tool according to claim 1, wherein: the thickness of the detection sleeve (1) is larger than the length of the semicircular key (2).
