Convenient checking tool for tooth jump detection of plate type parts

Abstract

The invention relates to a convenient checking tool for tooth jump detection of plate type parts. The checking tool comprises a base plate, a positioning mandrel, a measuring rod, a dial indicator, a fixed seat, a movable rod mechanism assembly, a fixed plate, a push rod and a slide rail. The slide rail is arranged at the base plate; the fixed seat is arranged above the slide rail; the dial indicator is arranged above the fixed seat; the movable rod mechanism assembly is arranged at the right side of the fixed seat; the fixed plate is arranged at the right side of the movable rod mechanism assembly; the push rod is arranged at the right side of the fixed plate; the measuring rod is arranged at the left side of the fixed seat; and the positioning mandrel is arranged at the left side of the measuring rod. The convenient checking tool has advantages of excellent usage performance, low using cost, great convenience in mounting, high detection precision, and simple structure.

Description

technical field [0001] The invention relates to a convenient inspection tool for detecting tooth jumps of disk parts, in particular to the detection of tooth jumps of gears. Background technique [0002] Every gear needs to be tested for tooth jump after processing, or many disc parts need to be tested. Due to the structural characteristics of the gear itself, it is necessary to use a mandrel to fix the parts during detection, but the size of the gears required by different products is different, which will lead to different apertures of the gears; while the existing tooth jump detection is basically All go to the inspection station, set the gear on the special taper mandrel, and then install it between the two tops with a deflection meter, and detect the runout of the ring gear of the workpiece through the measuring head and dial indicator; When the hole diameter is different, different taper mandrels are required. The taper mandrel is basically 380mm long, and the materia...

Due to the structural characteristics of the gear itself, it is necessary to use a mandrel to fix the parts during detection, but the size of the gears required by different products is different, which will lead to different apertures of the gears; while the existing tooth jump detection is basically All go to the inspection station, set the gear on the special taper mandrel, and then install it between the two tops with a deflection meter, and detect the runout of the ring gear of the workpiece through the measuring head and the dial indicator; When the hole diameter is different, different taper mandrels are required. The taper mandrel is basically 380mm long, and the material consumption is large. It is expensive to manufacture according to different hole diameters, which indirectly leads to an increase in the use cost and low performance; in addition, the large hole diameter When the gear is tested, it is very inconvenient to install due to the heavy weight of the tapered mandrel itself and the weight of the parts.
