Description

Technical Field

[0001] The utility model relates to the technical field of detection auxiliary instruments, and particularly relates to a probe for measuring the depth difference of parts. Background Art

[0002] The depth difference refers to the matching deviation caused by the machining precision deviation at the parting surface positions such as two mold inserts or the front and rear molds. Making a depth difference in mold design is to prevent the false appearance of excessive glue caused by incomplete machining, but it is deliberately designed. And some depth differences are unacceptable, for example, the appearance has a depth difference. After retrieval, a probe for measuring the depth difference of parts is disclosed in the Chinese patent with the authorization announcement number CN213351764U, which includes a probe rod. The top end of the probe rod is connected with a magnet base, and a probe is installed at the center position of the bottom end. The magnet base is adsorbed on the tool holder of the processing machine tool, and the probe is used to contact the workpiece at multiple points to measure the depth difference of the part. The utility model realizes the detection of the depth difference of parts during the processing process, does not require independent additional detection steps, saves labor, and improves production efficiency.

[0003] However, the overall structure of the probe in this scheme is fixed. Among them, the two probes can only point to fixed directions at the bottom end of the probe rod and cannot be adjusted in angle, resulting in certain limitations in the use process.

[0004] Therefore, we make improvements on this and propose a probe for measuring the depth difference of parts. Content of the Utility Model

[0005] In order to solve the problem that the existing probe cannot be adjusted, the utility model provides a probe for measuring the depth difference of parts.

[0006] The utility model is realized as follows:

[0007] A probe for measuring the depth difference of parts includes a probe rod and a pair of probe bodies. A direction adjusting component is installed at the bottom end of the probe rod. The bottom end of the direction adjusting component is rotatably connected with a rotating rod. A swing angle component is arranged on one side of the outer wall of the rotating rod. The pair of probe bodies are respectively installed at the swing angle component and the bottom end of the rotating rod. A locking mechanism is arranged at the top end of the swing angle component.

[0008] Further, the direction adjusting component includes a housing, a worm, a worm gear and a knob. The two sides inside the housing are respectively rotatably connected with the worm and the worm gear, and the worm and the worm gear are meshed with each other.

[0009] The beneficial effect of adopting the above further scheme is that by the cooperation of the worm and the worm gear, when the worm rotates, it can drive the rotating rod to rotate, and by using the self-locking characteristic of the worm and the worm gear, the rotating rod will not rotate by itself.

[0010] Furthermore, one end of the rotating rod extends to the interior of the housing and is sleevedly connected to one side of the worm gear.

[0011] The beneficial effect of adopting the above further scheme is that, through the connection between the rotating rod and the worm gear, when the knob is twisted, the rotating rod cooperates with the mechanical transmission of the worm and the worm gear to drive the two sets of probe bodies to rotate in circles at specified angles.

[0012] Furthermore, the outer wall of the shell is rotatably connected to a knob, and one end of the knob is connected to one end of the worm.

[0013] The beneficial effect of adopting the above further solution is that the rotation of the worm is made more convenient through the connection and use of the knob.

[0014] Furthermore, the swing angle assembly includes a fixing frame and an axis pile, the interior of the fixing frame is rotatably connected to the axis pile, and one side of the outer wall of the axis pile is connected to the top end of one of the probe bodies.

[0015] The beneficial effect of adopting the above further solution is that, by rotating the shaft pile inside the fixing frame, it can drive one of the probe bodies to adjust the inclination angle.

[0016] Furthermore, the locking mechanism includes a rotary rod and an arc-shaped pressure plate, the rotary rod is threadedly connected to the top end of the fixing frame, and the bottom end of the rotary rod extends to the inside of the fixing frame and is rotatably connected to the top end of the arc-shaped pressure plate.

[0017] The beneficial effect of adopting the above further solution is that the arc-shaped pressure plate contacts the shaft pile by rotating and pressing the rotary rod downward, thereby facilitating the compression and fixing of the shaft pile, and promoting the probe body to remain stable at a specified inclination angle.

[0018] Furthermore, a gap is provided between the bottom end of the arc-shaped pressure plate and the outer wall of the shaft pile.

[0019] The beneficial effect of adopting the above further solution is that the shaft pile can rotate smoothly through the setting of the gap.

[0020] Furthermore, the probe rod comprises a rod body and a cavity, and the cavity is arranged inside the rod body.

[0021] The beneficial effect of adopting the above further solution is that, by providing the cavity, the weight of the probe rod can be reduced, thereby making it more convenient to take and place the probe.

[0022] Furthermore, a magnetic seat is provided at the top of the probe rod, and the magnetic seat includes a seat body and a threaded sleeve. The bottom end of the seat body is connected to the threaded sleeve, and the inside of the threaded sleeve is threadedly connected to the top end of the rod body.

[0023] The beneficial effect of adopting the above further solution is that, through the connection and use of the threaded sleeve, a detachable connection is formed between the probe rod and the magnetic suction seat.

[0024] Furthermore, the probe body comprises a needle rod, a necked rod and a ball head, the bottom end of the needle rod is provided with a necked rod, and the bottom end of the necked rod is threadedly connected to the ball head.

[0025] The beneficial effect of adopting the above further solution is that the ball head can be easily disassembled, assembled and replaced by utilizing the threaded connection relationship between the ball head and the necked rod.

[0026] The beneficial effect of the utility model is that through the mutual cooperation of the direction adjustment component, the rotating rod, the swing angle component and the locking mechanism, the probe has an adjustable function, so that it is suitable for the use of different parts with different depth differences, wherein, by turning the knob and cooperating with the mechanical transmission between the worm and the worm wheel, the worm wheel drives the rotating rod to rotate in a circle, thereby completing the adjustment of the circumferential angle of the two sets of probe bodies, and then by toggling one of the probe bodies, the inclination angle is adjusted around the axis pile, and the axis pile is squeezed and fixed by the locking mechanism, so that the probe body is kept stable at the specified inclination position.
