Description

Technical Field

[0001] The present application relates to an in-mold steel ball implantation mechanism. Background Art

[0002] Steel ball parts are widely used as rolling elements. The installation and installation quality of steel ball parts have a significant impact on the production of steel ball parts. Because steel ball parts are small and can roll at any time and are scattered, it is difficult to achieve automated installation of steel balls during installation.

[0003] Usually, when installing steel balls in the existing technology, there is no dedicated steel ball installation equipment, and workers need to install them manually. The installation efficiency is low, the number of steel balls is large, and there are cases of missing installation. It is difficult to detect and find until the next step, resulting in defective steel ball parts, affecting the production yield of steel ball parts. Due to the special structure of the steel ball parts that are easy to roll, it is difficult to locate and transmit them during transmission and installation. Therefore, it is necessary to develop a new mechanism to solve the above technical problems. Utility Model Content

[0041] Please refer to Figures 1 to 11 As shown, an in-mold steel ball implanting mechanism disclosed in the present application is integrated into an automatic machine mold frame / machine platform. It is mainly used for the transmission and feeding of steel balls, and realizes the feeding of steel balls individually into the steel ball parts 7 to be assembled.

[0042] The in-mold steel ball implanting mechanism includes: a frame, which is formed with a frame table 1; a positioning block 2, which is stacked above the frame table 1, and the positioning block 2 is formed with an implantation groove 20 extending in the up-down direction and opening upward, a first positioning groove 201, a second positioning groove 202, a driving groove 203, and a pushing groove 204 connected to the bottom of the implantation groove 20, the driving groove 203 and the pushing groove 204 are formed into an opening shape from the lower surface of the positioning block 2 downward, the positioning block 2 is attached to the upper surface of the frame table 1 to close the lower end openings of the driving groove 203 and the pushing groove 204, the implantation groove 20 is used for implanting steel balls, and the driving groove 203 and the pushing groove 204 are located in the same straight line extending in the left-right direction. On the top, the first positioning groove 201 extends along the front-to-back direction perpendicular to the left-to-right direction, and the extension direction of the second positioning groove 202 overlaps or is parallel to the extension direction of the first positioning groove 201; the steel ball transmission pipeline 3 is connected to the upper end opening of the implantation groove 20; the stepping rod 4, one end of which is inserted into the driving groove 203, and can reciprocate along the left-to-right direction; the first positioning rod 5, one end of which is inserted into the first positioning groove 201, and can reciprocate along the front-to-back direction; the second positioning rod 6, one end of which is inserted into the second positioning groove 202, and the end of the second positioning rod 6 is formed with a pressing slope 60, and the pressing slope 60 faces the stepping rod 4 and the first positioning rod 5.

[0043] The stepping rod 4, the first positioning rod 5, and the second positioning rod 6 respectively press against the outer surface of the steel ball from three directions to position the steel ball in the implantation slot 20. Specifically, the stepping rod 4 presses against the outer surface of the steel ball from back to front; the first positioning rod 5 presses against the position between the upper and lower steel balls from right to left; the second positioning rod 6 presses against the outer surface of the steel ball toward the right rear; the steel ball at the bottom is accommodated in the driving slot 203 and supported on the rack table 1, thereby realizing the positioning of the steel ball. Specifically, the first positioning rod 5 presses between the two adjacent steel balls at the bottom from right to left.

[0044] Furthermore, the end of the first positioning rod 5 is tapered. The first positioning rod 5 reciprocates in a straight line along the extension direction (left-right direction) of the first positioning slot 201. The limit position of the end of the first positioning rod 5 moving toward the second positioning rod 6 along the front-back direction does not exceed the axis of the implantation slot 20. The height of the portion of the second positioning rod 6 extending into the drive slot 203 along the up-down direction is less than 1.5 times the diameter of a single steel ball. Preferably, the height of the portion of the second positioning rod 6 extending into the drive slot 203 along the up-down direction is less than the diameter of a single steel ball. Such a design can prevent the second positioning rod 6 from rubbing against the steel ball above the lowest steel ball when in action.

[0045] The second positioning rod 6 is a swing rod, and the swing fulcrum 61 of the second positioning rod 6 and the driving slot 203 are located on the same side of the extension line of the second positioning slot 202. The second positioning rod 6 is pushed by a compression spring, and the end of the second positioning rod 6 is normally pressed to protrude into the driving slot 203.

[0046] The operating principle of the steel ball implantation mechanism of this application is introduced below:

[0047] Initial state: At this time, the steel ball located at the bottom (hereinafter referred to as the first steel ball) is accommodated in the driving groove 203 and supported on the frame table 1, and the stepping push rod 4 is pressed against the outer surface of the first steel ball from back to front; the first positioning rod 5 is pressed from right to left between the first steel ball and the second steel ball located above the first steel ball; the second positioning rod 6 is pressed against the outer surface of the steel ball toward the right rear, thereby realizing the positioning of the steel ball.

[0048] Feeding process: When the end of the stepping push rod 4 moves in the driving groove 203 to push the first steel ball from the driving groove 203 to the ejection groove 204, it simultaneously directly or indirectly pushes the second positioning rod 6 to press the inclined surface 60 to push the end of the second positioning rod 6 back into the second positioning groove 202. At least part of the end of the first positioning rod 5 hovers directly above the stepping push rod 4 and remains motionless. The end of the first positioning rod 5 limits the second steel ball located above the second positioning rod 6 in the implantation groove 20 to prevent the steel ball from falling down to the driving groove 203.

[0049] Reset process: the end of the stepping propulsion rod 4 is retracted from the ejection slot 204 to the driving slot 203. At this time, the end of the second positioning rod 6 is pushed by the compression spring (not shown) and resets into the driving slot 203. At this time, the end of the first positioning rod 5 is still suspended directly above the stepping propulsion rod 4 and remains motionless.

[0050] Preparation process: the end of the first positioning rod 5 is driven to retract into the first positioning slot 201, the second steel ball is separated from the end of the first positioning rod 5 and falls into the driving slot 203, and then the end of the first positioning rod 5 extends from the first positioning slot 201 to the driving slot 203, and finally forms the above initial state. The feeding and preparation process of a steel ball is completed.

[0051] In the embodiment of the present application, the first positioning rod 5 is an active member, which is driven by a driving mechanism (not shown), which can be a cylinder or a linear motor. Of course, in other embodiments, the first positioning rod 5 can also be driven by a passive driving element (such as a compression spring).

[0052] Through the implementation scheme of the present application, the stable transmission and positioning of the steel ball can be achieved, and the feeding of a single steel ball can be achieved without causing friction and impact damage to other steel balls during the feeding process.

[0053] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
