Problems solved by technology

[0002] When drilling a center hole on an ordinary drilling machine, the depth is usually driven by the tailstock sleeve of the manual operation machine tool to drill the center hole to the part. This method cannot effectively guarantee the accuracy of the hole depth and size, resulting in poor positioning references.

Embodiment Construction

[0013] from figure 1 , figure 2 As can be seen in the figure, a kind of automobile semi-axis central hole processing depth control device is installed and fixed on the drill rig taper shank 15 with a support sleeve 2, and is pressed with screw 43 and the screw hole on the support sleeve 2. Said bracing sleeve 2 tops install dial indicator 1 by fixed rod, and said dial indicator 1 table rod inserts in the hole of fixed rod 3 tops, presses fixed table rod by side screw hole with screw 41. The lower part of the fixed rod 3 is welded on the support sleeve 2. The specific composition and structure of the dial gauge 1 belongs to the prior art. The support sleeve 2 is fixedly connected with a guide sleeve 7 through the connecting plate 5 in the horizontal direction, the left end of the connecting plate 5 is welded with the support sleeve 2, and the right end is welded with the guide sleeve 10. An axially movable guide rod 10 is installed in the guide sleeve 7, the front end of th...

Abstract

The invention discloses an automobile semi-axle central hole machining depth control device. A supporting sleeve is fixedly installed on a drilling machine taper shank sleeve, a dial indicator is installed on the upper portion of the supporting sleeve through a fixing rod, a guiding sleeve is fixedly connected to the supporting sleeve through a connecting plate in the horizontal direction, a guiding rod capable of axially moving is installed in the guiding sleeve, the front end of the guiding rod makes contact with the end face of a part, the back portion of the guiding rod is connected with atouch plate, and the touch plate makes contact with the head of the dial indicator. When drilling feeding is conducted, the guiding rod and the touch plate move backwards to make contact with the head of the dial indicator, and the drilling depth is controlled by observing readings of the dial indicator. The automobile semi-axle central hole machining depth control device is reasonable in structure, convenient to operate and use and high in size control precision.

Description

technical field [0001] The invention relates to a drilling depth control device, in particular to a processing depth control device for a center hole of an automobile half shaft. Background technique [0002] When drilling a center hole on an ordinary drilling machine, the depth is usually driven by the tailstock sleeve of the manual operation machine tool to drill the center hole to the part. This method cannot effectively guarantee the accuracy of the hole depth and size, resulting in poor positioning references. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a device for controlling the processing depth of the central hole of the automobile half shaft with reasonable structure, convenient operation and use, and high dimensional control precision. [0004] The technical solution adopted by the present invention to solve the above-mentioned technic...
