Problems solved by technology

The existing technology of riveting oil duct plugs has the following disadvantages: 1. A plug often needs to be tapped several times before it can be installed in place, and the operation is complex, labor-intensive, and inefficient
2. If the force of beating is improper, the punch will not only easily damage the workpiece, but also pose a hidden danger to human safety.
3. With manual operation based on experience, it is difficult to control the riveting depth of the plug, which seriously affects the assembly quality

Embodiment

[0030] According to the position of the oil passage plug on the crankcase body that needs to be riveted in, determine that the crankcase body plug should be riveted from several different directions around the side of the case body. Yingquan calculates how much pressure is needed to press the plug into place, and then selects an oil cylinder with a suitable bore diameter according to the calculated pressure.

[0031] The invention as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5-1 , Figure 5-2 As shown, a crankcase plug riveting device includes a base 1 , a workpiece positioning and clamping mechanism 2 and a riveting actuator 3 arranged on the same base 1 .

[0032] The workpiece positioning and clamping mechanism 2 includes a workpiece supporting seat 21 fixedly connected with the base 1, a supporting column 22, a workpiece pressing rod 241, a pressing plate 24, an upper supporting plate 23 and a workpiece clamping oil cylinder 25 arranged sequentially from b...

Abstract

The invention discloses a crankcase body plug riveting device. The plug riveting device comprises a base (1), a workpiece positioning and clamping mechanism (2) and a riveting execution mechanism (3), wherein the workpiece positioning and clamping mechanism (2) and the riveting execution mechanism (3) are arranged on the same base (1); the workpiece positioning and clamping mechanism (2) comprises a workpiece support seat (21), a support column (22), a workpiece pressing rod (241), a pressure plate (24), an upper support plate (23) and a workpiece clamping oil cylinder (25), which are sequentially arranged from bottom to top and are fixedly connected with the base (1); the riveting execution mechanism (3) is set to be of the same structure which corresponds to an oil duct plug on a crankcase body in to-be-riveted position, inner diameter and quantity; and the riveting execution mechanism (3) comprises an oil cylinder (31), a guide component II and a pressure head component, which are arranged on angle iron which is fixedly connected with the base (1). The plug riveting device is reasonable in structural design, low in cost, high in automatic degree and convenient and reliable to use; the riveting assembling quality of the oil duct plug is ensured; the labor intensity is relieved; and the work efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a crankcase plug riveting device. It is an automatic riveting device for multiple oil channel plugs in the crankcase body. Background technique [0002] At present, the riveting of the oil passage plugs in multiple directions of the crankcase body usually uses special tooling fixtures to position and clamp the crankcase body, and then uses punches and hammers to hit the plugs to rivet the plugs, and then pull them out after riveting. The indexing plate positioning pin rotates the fixture indexing plate so that the position of the oil passage hole to be riveted into the next plug of the box body is vertically upward, and then inserts the indexing positioning pin to lock the position of the indexing plate, and then proceeds to the next plug in sequence Riveted in. The existing technology of riveting oil passage plugs has the following disadvantages: 1. A plug often needs to be kn...
