The invention discloses a two-time positioning drilling clamp for an engine body reinforcing plate. The two-time positioning drilling clamp for the engine body reinforcing plate comprises a base, two first positioning pins, a second positioning pin, two third positioning pins and a locking mechanism, wherein the two first positioning pins are arranged on the left side of the base front and back along the same straight line; the second positioning pin is arranged on the base; when first-time drilling is carried out, the left wall surface of an inner cavity of the engine body reinforcing plate abuts against the two first positioning pins, and one partition plate of the inner cavity of the engine body reinforcing plate abuts against the second positioning pin; the two third positioning pins are arranged on the base, and when second-time drilling is carried out, the two third positioning pins are sleeved with two holes, formed through first-time drilling, of the engine body reinforcing plate correspondingly; and the engine body reinforcing plate is locked and fixed by the locking mechanism. Through the two-time positioning drilling clamp for the engine body reinforcing plate, the engine body reinforcing plate can be clamped and positioned on the base two times, and therefore all drilling work can be completed on universal equipment with a limited travel, and machining cost is lowered.
Description
technical field [0001] The invention relates to the field of fixtures, in particular to a secondary positioning drilling fixture for machine body reinforcement plates. Background technique [0002] The body reinforcement plate is an important part of the engine, and the oil pan of the engine is fixed to the lower end of the body of the engine through the body reinforcement plate. The length of the reinforced plate of the body is long and the number of holes is large. Due to the limited processing stroke of general-purpose equipment, it is difficult to process all the holes after a certain installation and positioning of the reinforced plate of the body. Drilling of the reinforcing plate usually requires the use of a large numerically controlled machine tool, and its equipment cost is relatively high, which will increase the cost of producing the body reinforcing plate. [0003] The information disclosed in this Background section is only for enhancing the understanding of t...
