Description

Technical Field

[0001] This utility model belongs to the field of sensor processing technology, and in particular relates to a force-sensitive sensor equidistant milling device. Background Technology

[0002] A force sensor is a device that can sense external force and convert it into an electrical signal output. Force sensors are usually composed of elastic elements, resistance strain gauges and other auxiliary components. In the production process of force sensors, milling is an important machining process, which mainly uses a rotating milling cutter to machine holes in the workpiece. Precise and equidistant hole positions are crucial to the performance and installation of the sensor.

[0003] The accuracy of the hole positions on the sensor housing directly affects subsequent sensor installation. Positioning the sensor housing before milling is often complex and difficult to control precisely, leading to inconsistent hole spacing and affecting sensor quality and assembly accuracy. Therefore, a force-sensitive sensor equidistant milling device is needed. First, an internal support clamping method is used to achieve rapid positioning, ensuring that the sensor center is located at the center of the feeding table. Then, a photoelectric sensor precisely controls the rotation angle of the sensor housing to achieve equidistant milling, ensuring accurate hole positions and improving production efficiency and product quality.

[0021] In the following description, embodiments of the force-sensitive sensor equidistant milling device of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an embodiment of a force-sensitive sensor equidistant milling device, comprising a processing table 1. A feeding turntable 2 is rotatably connected to the top of the processing table 1. A milling machine 3 is fixedly installed on the rear side of the top of the processing table 1. A positioning component 4 is provided in the inner cavity of the feeding turntable 2. The positioning component 4 includes four limiting grooves 41 annularly formed on the top of the feeding turntable 2. Displacement sliders 42 are slidably connected to the inner cavity of the limiting grooves 41. Limiting pins 6 are fixedly connected to the surface of the displacement sliders 42. The limiting pins 6 are slidably connected to the inner cavity of the limiting grooves 41. A return spring 7 is sleeved on the surface of the limiting pins 6. One end of the return spring 7 is welded to the limiting groove 41, and the other end of the return spring 7 is welded to the displacement slider 42. A clamping arm 43 is fixedly connected to the top of the displacement slider 42. An electric telescopic rod 44 is fixedly installed at the bottom of the feeding turntable 2. The output end of the electric telescopic rod 44 penetrates into the inner cavity of the feeding turntable 2 and is fixedly connected to a pressing cone 45. Each of the four displacement sliders 42 has a positioning component on one opposite side. A conical groove 46 adapted to the extrusion cone 45 is provided. Driven by the electric telescopic rod 44, the extrusion cone 45 and the conical groove 46 work together to extrude four displacement sliders 42 simultaneously, thereby causing four clamping arms 43 to move in opposite directions simultaneously, thus providing internal support and positioning for the sensor housing. The inner cavity of the processing table 1 is provided with a distance fixing component 5. A rotating tube 51 is fixedly connected to the bottom of the feeding turntable 2. A servo motor 52 is fixedly installed on the right side of the inner cavity of the processing table 1. A pulley 53 is fixedly connected to the surface of the rotating tube 51 and the output shaft of the servo motor 52. The two pulleys 53 are connected by belt drive. Driven by the servo motor 52 and working together with the pulleys 53 and belt, the feeding turntable 2 is driven, causing the sensor housing to rotate, thereby adjusting the position of the milled hole of the sensor. Four photoelectric position sensors 54 are distributed in a ring at the four corners of the bottom of the feeding turntable 2. A photoelectric positioning sensor 55 is fixedly installed on the right side of the top of the inner cavity of the processing table 1.

[0023] Working principle: When using this utility model, the user places the sensor housing on top of the feeding turntable 2, so that the sensor housing is fitted onto the surface of the four clamping arms 43. Then, the electric telescopic rod 44 is activated, which pushes the extrusion cone 45 upward. Under the cooperation of the conical surface of the extrusion cone 45 and the conical groove 46, the four displacement sliders 42 are squeezed and move in opposite directions, thereby causing the four clamping arms 43 to move in opposite directions, providing internal support and clamping for the sensor housing. At the same time, the return spring 7 is compressed. Then, the milling machine 3 is activated to mill the first hole. After milling is completed, the servo motor 52 is activated and... Under the transmission action of the belt and belt pulley 53, the rotating tube 51 rotates. During the rotation of the rotating tube 51, the sensor housing is rotated through the feeding turntable 2. During the rotation of the feeding turntable 2, the photoelectric position sensor 54 at its bottom is displaced. When one of the photoelectric position sensors 54 approaches the photoelectric positioning sensor 55, the motor controller receives the positioning signal and controls the servo motor 52 to stop. At this time, the secondary milling can be performed. Since the four photoelectric position sensors 54 are evenly distributed and the distance between two photoelectric position sensors 54 is ninety degrees, the distance between each milling is also ninety degrees.

[0024] In summary, this force sensor equidistant milling device, through the combined use of the feeding turntable 2 and the positioning component 4, internally supports and fixes the sensor housing. Then, the milling machine 3 mills holes on its top. Simultaneously, with the cooperation of the distance fixing component 5, the sensor housing is rotated at a fixed angle to perform multi-hole milling, thus achieving the purpose of fast and convenient positioning and accurate equidistant milling position.
