Detailed Description
in order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
An embodiment of the present invention provides a rocker arm positioning carrier, as shown in fig. 1 and 2, including a base 100, a central positioning block 200, a cushion block 300 and a vertical positioning bolt 400. The base 100 is provided with a positioning groove 110, and the center positioning block 200 is disposed on the bottom surface of the positioning groove 110. The center positioning block 200 is configured to be snapped into a gap between the upper arcuate flanges of the rocker arm 10 for horizontal X-axis positioning (with respect to the Y-axis and Z-axis directions described below) of the rocker arm 10. The central positioning block 200 includes a positioning block 210 and a plurality of positioning protrusions 220, and the positioning protrusions 220 are disposed on the side end surface of the positioning block 210. Preferably, the positioning protrusion 220 is connected to the positioning block 210 by a threaded connection, that is, the bottom end of the positioning protrusion 220 is provided with a thread, the positioning block 210 is provided with a threaded counter bore matched with the positioning protrusion 220, and the protrusion height of the positioning protrusion 220 is determined according to the specific shape of the rocker arm 10. The cushion block 300 and the vertical positioning bolt 400 are arranged on the top end face of the base 100 and are close to the positioning groove 110, the cushion block 300 and the positioning bolt 400 are connected with the base 100 in a threaded connection mode, and the cushion block 300 and the positioning bolt 400 are used for positioning two ends of the rocker arm 10 in the length direction and preventing the rocker arm from moving up and down or left and right, namely positioning in the Y-axis direction and the Z-axis direction.
As shown in fig. 2, bosses 120 perpendicular to the top end surface of the susceptor 100 are provided on both sides of the susceptor 100 in the longitudinal direction, and threaded holes are provided through the bosses 120 and bolts are provided in the threaded holes. The movement of the swing arm 10 in the left-right direction is further accurately restricted by the extension or contraction of the bolt in the base 100.
Furthermore, the base 100 is further provided with a through groove 130, and a length direction of the through groove 130 is perpendicular to a length direction of the positioning groove 110. The positioning groove 110 is provided with a through groove 130 which can form an opening, so that the rocker arm 10 can be taken and placed conveniently.
Preferably, the central positioning block 200 is detachably connected to the base 100. When the rocker arm 10 is different in size, the center positioning block 200 may need to be replaced in a different shape.
