Problems solved by technology
For connecting rods and connecting rod caps whose butt joint end faces are connected by serrated surface, it is necessary to check the degree of fit and the surface roughness of the serrated surface. These two inspections are time-consuming and laborious.
[0003] The existing roughness meter uses the electric touch method to measure the roughness of the processed surface, which is only suitable for plane detection with a simple structure, and it is difficult to detect the roughness of the inclined side of the sawtooth
It is necessary to constantly adjust the relative position of the connecting rod and the probe, which takes a long time and seriously affects the production progress of the diesel engine

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1 ~ Figure 3 As shown, the present invention includes a roughness detection probe 1, a probe clamping block 2, a horizontal positioning plate 3 and a handle 4, figure 1 The shape of the middle probe clamping block 2 is a right-angled trapezoidal block set by tilting. The bottom of the right-angled trapezoidal block is fixed on the left end of the horizontal positioning plate 3, and the middle part of the roughness detection probe 1 is installed obliquely on the probe clamping block. 2. Inside the top, the lower end of the roughness detection probe 1 protrudes obliquely from the probe clamping block 2, and the probe 11 side of the lower end of the roughness detection probe 1 is attached to the tooth surface side of the sawtooth 101. The lower side of the right end of the horizontal positioning plate 3 is fixedly connected with the...

The invention discloses a special-purpose diesel engine connecting rod tooth surface roughness detection device. The device comprises a roughness detection probe, a probe clamping block, a horizontal positioning plate and a handle, wherein a bottom portion of the probe clamping block is fixed at one end of the horizontal positioning plate, a middle portion of the roughness detection probe is obliquely arranged in a top portion of the probe clamping block, one side of a probing needle of a lower end head of the roughness detection probe fits one side of a tooth surface of an end surface sawtooth at a transverse end of a connecting rod of a diesel engine, the other end of the horizontal positioning plate is supported on an end surface of another transverse end of the connecting rod of the diesel engine, one end of the handle is fixed at one side of the probe clamping block, and one end of the handle is fixed at an upper side of the other end of the horizontal positioning plate. According to the device, the structure is compact, the device is convenient to carry and operate, a problem that a sawtooth inclination side surface can not be easily detected by a roughness instrument in the prior art is solved, and strong versatility is realized. The device is further advantaged in that roughness detection precision and detection efficiency of a sawtooth surface are improved, and detection cost is reduced.
Description
technical field [0001] The invention relates to a roughness detection device of an inclined processing surface, in particular to a narrow tooth surface roughness detection device used for connecting the end face of a connecting rod of a diesel engine and the end face of a connecting rod cover, and belongs to the technical field of detection of metal cutting workpieces. Background technique [0002] The upper and lower ends of the connecting rod of the diesel engine are respectively connected to the crankshaft and the piston, and are the key components for transmitting the motion of the crankshaft and the piston. When the diesel engine is working, the connecting rod bears the alternating stress of tension and yield, and must have certain anti-fatigue properties to ensure that the diesel engine can work stably for a long time. At present, there are two ways to connect the connecting rod and the connecting rod cover. One is that the butt end faces are in plane contact and are c...
