Abstract
The utility model discloses a semicircular key installation tool, which comprises a tool body, wherein the working surface on the tool body is a plane, a groove with a cross section of "" is arranged on the working surface in an inwards concave manner and is used for installing a semicircular key, the groove width is equal to the working length L of the semicircular key, and the groove depth is smaller than the height h of the semicircular key; the right-angle joint of the groove bottom and the groove wall is provided with a abdicating groove with a circular arc-shaped section. The advantages are that: according to the installation tool for the semicircular key, the semicircular key is installed in the tool body, the semicircular key is knocked in parallel, two right-angle edges are not damaged, and the pump shaft can be easily installed into the gear.
Description
Technical Field
The utility model relates to a semicircle key mounting tool.
Background
Generally use the bar copper to strike the keyway of pump shaft when installing the semicircle key usually in addition, because the semicircle key is smaller, do not take well, cause the semicircle key size of knocking into not in place, not parallel with the pump shaft, often beat the hair to two limits of semicircle key when knocking the semicircle key moreover, beat out the opening to unable normal packing in the time of leading to adorning the gear.
Disclosure of Invention
The utility model provides a simple structure, reliable, convenient to use's semicircle key mounting tool solves above-mentioned technical problem effectively.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a semicircular key installation tool comprises a tool body, wherein the working surface of the tool body is a plane, a groove with a cross section being in a shape of' is concavely arranged on the working surface and is used for accommodating a semicircular key, the groove width is equal to the working length L of the semicircular key, and the groove depth is smaller than the height h of the semicircular key; the right-angle joint of the groove bottom and the groove wall is provided with a abdicating groove with a circular arc-shaped section.
The semicircular key is clamped in the groove of the tool body, the horizontal plane of the semicircular key faces the bottom of the groove, and the two right-angle sides at the joint of the arc surface of the semicircular key and the horizontal plane correspond to the two yielding grooves.
To the utility model discloses technical scheme's preferred, the instrument body is the rectangular plate.
Compared with the prior art, the utility model, its beneficial effect is:
the utility model discloses a semicircle key mounting tool, low in process cost, modern design, simple structure, convenient to use.

Detailed Description
The technical solution of the present invention is explained in detail below, but the scope of protection of the present invention is not limited to the embodiments.
In order to make the disclosure of the present invention more comprehensible, the following description is further made in conjunction with fig. 1 to 3 and the detailed description.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Example (b):
as shown in fig. 1 and 2, the installation tool for a semicircular key of the present embodiment includes a tool body 1, wherein a working surface of the tool body 1 is a plane, and a groove 11 with a cross section of "" shaped for installing a semicircular key is concavely formed on the working surface.
The tool body 1 is a rectangular plate, and a groove 11 with a cross section being "" shaped and used for containing a semicircular key is concavely arranged on one side plane of the rectangular plate. As shown in fig. 3, the width of the slot 11 is equal to the working length L of the half-round key, and the depth of the slot 11 is smaller than the height h of the half-round key; and abdicating grooves 12 with circular arc-shaped sections are arranged at the right-angle joint of the groove bottom and the groove wall of the groove 11.
The semicircular key is clamped in the groove 11 of the tool body 1, the horizontal plane of the semicircular key faces the bottom of the groove 11, and two right-angle sides at the joint of the arc surface of the semicircular key and the horizontal plane correspond to the two yielding grooves.
Because this instrument body 1 has opened two convex groove 12 of stepping down at the right angle, when the semicircle key was packed into, two right-angle sides of semicircle key do not contact with instrument body 1, when knocking instrument body 1 and packing into the semicircle key, two straight flanges of semicircle key do not receive the force, more can not produce deformation. When the gear is installed, the semicircular key is knocked into the tool body and the pump shaft in parallel, so that the semicircular key is also parallel to the pump shaft, and the two right-angle edges are not damaged, so that the gear can be easily installed.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
