Example two
The invention relates to a directional polishing method of a basalt fiber composite pipe 2, which comprises the following specific contents:
in the first step, the end part of the basalt fiber composite pipe 2 is clamped
The transmission supporting belt 1 drives the basalt fiber composite pipe 2 to advance, when any one of the photoelectric probes 401 senses and detects that any one end of the basalt fiber composite pipe 2 enters a vertical sensing detection range of the photoelectric probe 401 and a distance sensed and detected by the photoelectric probe 401 is not more than a clamping distance preset by a system (the system refers to a control system formed by a single chip microcomputer or an industrial computer), wherein the clamping distance is not more than the clamping distance when a vertical symmetrical plane 201 of the basalt fiber composite pipe 2 enters a clamping range of an initial position clamping plate 305, the distance sensed and detected by the photoelectric probe 401 is not more than the clamping distance, such as a detection distance L in figure 5, two cylinder assemblies 303 at an upper side position and two cylinder assemblies 303 at a lower side position of a current side end simultaneously act to position and clamp the current side end of the basalt fiber composite pipe 2. And (3) sensing and detecting the distance between any photoelectric probe 401 at the position of the other side end of the basalt fiber composite pipe 2 and the basalt fiber composite pipe 2, comparing and judging the distance with the 'entering clamping distance', and finishing positioning and clamping on the other side end of the basalt fiber composite pipe 2 through a cylinder assembly 303 at the position of the other side end of the basalt fiber composite pipe 2.
Second, the position of the 2 side end of the basalt fiber composite pipe is found
The photoelectric probes 401 of the photoelectric distance sensing module 4 downwards perform distance detection on the basalt fiber composite tube 2, and the position of the photoelectric probe 401 at which the first distance detection is greater than the preset tube end distance of the system (the tube end distance is the distance between the photoelectric probe and the highest point of the basalt fiber composite tube 2, such as the distance "H" in fig. 4) is analyzed and judged along the direction from the middle part to the side end of the basalt fiber composite tube 2, and the photoelectric probe 401 at the position is recorded as a polishing start photoelectric probe. After the two side ends of the basalt fiber composite pipe 2 in the first link are positioned and clamped, when the middle side end in the second link is positioned, all photoelectric probes 401 at any side end position of the basalt fiber composite pipe 2 do not sense and detect that the distance is larger than a preset pipe end distance of a system, the air cylinder assembly 303 at the current side end of the basalt fiber composite pipe 2 returns to the initial position, and the linear motor 302 drives the photoelectric distance sensing module 4 and the air cylinder assembly 303 to translate towards the position of the side end of the basalt fiber composite pipe 2 until a distance parameter sensed and detected by one photoelectric probe 401 is larger than the preset pipe end distance of the system.
And step three, polishing and positioning the basalt fiber composite pipe 2
According to the preset polishing propelling depth (polishing depth towards the direction of the basalt fiber composite pipe 2) of the system and the sensing distance distributed among all the photoelectric probes 401 (the photoelectric probes vertically and downwards sense and detect the distance, and a certain distance exists when the adjacent photoelectric probes 401 are designed and installed, the invention does not adopt a CCD-like dense high-precision design, firstly, distance sensing detection is needed, secondly, only a unidirectional (transverse) distribution design is needed in the invention, the requirement on precision is not too high, the precision is too high, the delayed reaction depth of an industrial control system per se cannot be kept up with the requirement, in addition, the design of the invention can reduce the control difficulty to a certain extent and also reduce the cost of devices), the position of the photoelectric probe 401, which is just opposite to the end face of the basalt fiber composite pipe 2 in the vertical direction when polishing is finished, is analyzed and judged, and the photoelectric probe 401 at the position is recorded as a polishing finished photoelectric probe.
Polishing the 2 side end of the basalt fiber composite pipe
And (3) the transverse moving driving device 5 pushes the polishing motor 6 to push towards the basalt fiber composite pipe 2, the sliding sleeve 9 is inserted into the pipe cavity of the basalt fiber composite pipe 2, and when the distance information sensed by the polishing start photoelectric probe in the step (2) is not more than the pipe end distance preset by the system, the polishing motor 6 drives the polishing wheel 7 to rotate to start polishing the side end of the basalt fiber composite pipe 2. When the distance sensed by the photoelectric probe for finishing polishing in the step (3) is a short distance for polishing (the short distance for polishing is the distance when the photoelectric probe senses the polishing wheel 7, such as the distance "S" in fig. 6), polishing is stopped, the traverse driving device 5 drives the polishing motor 6 to return, the sliding sleeve 9 is separated from the basalt fiber composite tube 2, the cylinder assembly 303 drives the clamping plate 305 (such as the position when the clamping plate 305 is close to the cylinder assembly 303 in fig. 5) to return to the initial position, and the support belt transmission 1 continues to forward convey the basalt fiber composite tube 2 after polishing.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
