Drilling device for rim with spokes

Abstract

The invention discloses a drilling device for a rim with spokes. The drilling device comprises a supporting seat, a rack, a feed driving mechanism and a swing locking component, and the supporting seat is configured as a support component for installing a rim; the rack is located on one side of the supporting seat, and provided with a feed support plate which is provided with a drill bit; the feeddriving mechanism is used for driving the drill bit to feed or retract along a guide component; the feed support plate is provided with a first arc fitting part, and the rack is provided with a second arc fitting part which is in clamping fit with the first arc fitting part, so that the feed support plate can be swung relative to an arc path limited by the first arc fitting part and the second arc fitting part; the circle center corresponding to the arc path is located on the rim installed on the supporting seat; and the swing locking component is used for locking or unlocking the feed support plate. The drilling device has the advantages of convenient machining, accurate drilling position and convenient regulation.

Description

technical field [0001] The invention relates to wheel rim processing equipment, in particular to a drilling device for a spoked wheel rim. Background technique [0002] Wheel rim, also called wheel hub, the wheel rim used on automobiles is generally called wheel hub, and the wheel rim used on motorcycles, electric bicycles, and bicycles, some of which have spokes. Spokes are slender metal rods on the rim. The use of spoke connections can reduce the weight of the wheel, save material costs, and can also play a certain role in elastic deformation. The rim with spokes generally needs to use an inner tube in the tire. The driving requirements are met by inflating the inner tube. In order to connect the spokes on the rim, the adopted technical solution is to set some through holes on the rim, one end of the spokes passes through the through holes and is fastened to the inner rim wall, and the other end of the spokes is connected with the hub and tensioned. Wheels of different s...

AI Technical Summary

Problems solved by technology

Wheels of different specifications have different widths and wall thicknesses, and the corresponding hub parameters are also different. Therefore, the axis of the spoke holes on the rim does not necessarily pass through the axis of the rim, and these spoke holes may have a certain inclination. If The machining accuracy of the spoke holes of the rim is not enough, or the relative positions of the spoke holes are wrong, which will cause installation difficulties. If the spokes are installed forcibly, the spokes will be bent to a certain extent at the connection. The connection with the rim will generate a lot of stress. On the one hand, the strength of the rim will deteriorate and the bearing capacity will decrease. On the other hand, this shear stress may cause damage to the rim and lead to scrapping

At present, the drilling machines on the market, when processing the spoke holes of the rim, either have large deviations, that is, the exit position of the actually drilled hole, the extension direction of the hole, etc., or the adjustment is very cumbersome, and the processing is very inconvenient. , for this reason, the present invention is developed under such background
