[0034] The embodiment of the present application provides a hole position identification device 100, which can be used for hole position identification and alignment, and is specifically used for hole position alignment of head and tail plate through holes and end plate threaded holes in prestressed pipe piles. The hole position identification device 100 provided in the present application can improve hole finding efficiency and meet the needs of automated hole alignment scenarios.

[0035] Combination Figure 1 and Figure 2As shown, an embodiment of the present application provides a hole position identification device 100, which includes a workbench assembly 110, a detection assembly 120 and a processor 130. The workbench assembly 110 is used to fix the workpiece 200 to be measured; the detection assembly 120 is arranged on one side of the workbench assembly 110, and the detection assembly 120 includes a measuring member 121, which is used to measure the distance between the measuring member 121 and the workpiece 200 to be measured. The measuring member 121 is located on the side of the workpiece 200 to be measured away from the workbench assembly 110, and the workbench assembly 110 drives the workpiece 200 to be measured. 200 The processor 130 is electrically connected to the measuring member 121 , and the processor 130 receives the distance measurement signal of the measuring member 121 and calculates the hole center of the workpiece 200 to be measured.

[0036] For ease of understanding, the workpiece 200 to be measured in the embodiments of the present application can be illustrated by using head and tail plates.

[0037] Exemplarily, the head and tail plates are fixed to the workbench assembly 110, and the measuring piece 121 is located on one side of the workbench assembly 110, and the measuring piece 121 is located above the pitch circle of the head and tail plate holes, so that the hole positions of the head and tail plates can be measured. During the measurement process, one of the head and tail plates and the measuring piece 121 can rotate, such as the measuring piece 121 is fixed, and the workbench assembly 110 has a self-rotation function to drive the head and tail plates to rotate; or the head and tail plates remain fixed, and the measuring piece 121 can rotate along the axis of the head and tail plates. In this way, the measuring piece 121 can measure the edges of the holes on both sides, obtain the distribution angle of the holes, and finally obtain the center of the holes.

[0038] The measuring element 121 may be a distance measuring sensor, such as an ultrasonic distance measuring sensor, a laser distance measuring sensor, an infrared distance measuring sensor, a radar sensor, etc.

[0039] In this embodiment, the measuring element 121 may be a laser distance measuring sensor.

[0040] The processor 130 can be a processing computer with a corresponding calculation program installed inside. The distance parameters from the measuring piece 121 are received through the computer, and the end face distance between the measuring piece 121 and the head and tail plates is used as a threshold. When the edge of the hole of the head and tail plates is located at the ranging laser point of the measuring piece 121, an instantaneous signal of increasing or decreasing ranging will be generated, thereby obtaining the distribution angle of the two edges of the hole. The intersection of the midline of the distribution angle and the hole pitch circle is the center of the hole, thereby calculating the corresponding hole center to facilitate subsequent automatic alignment operations.

[0041] Combined Figure 6As shown, in the present application, the working principle of the hole position identification device 100 is as follows: fix the head and tail plates on the workbench assembly 110, adjust the measuring piece 121 to the pitch circle of the hole position, and the measuring piece 121 emits a distance measuring laser to measure the end face of the head and tail plates. The measuring piece 121 is provided with a distance measuring threshold, that is, the initial distance between the measuring piece 121 and the end face of the head and tail plates is within the threshold. During the measurement process, the workbench assembly 110 drives the head and tail plates to rotate. When the edge of one side of the hole position of the head and tail plates is located at the distance measuring laser point of the measuring piece 121, due to the depth of the hole position, the distance measurement value of the measuring piece 121 increases and exceeds the set distance measuring threshold. At this time, the measuring piece 121 sends an output signal to the processor 130. After receiving the signal, the processor 130 records the current angle. As the workbench assembly 110 drives the head and tail plates to continue rotating, the distance measuring laser of the measuring piece 121 is directed to the other side edge of the hole, and the distance measurement value of the measuring piece 121 decreases and returns to the set distance measuring threshold. At this time, the measuring piece 121 sends an output signal to the processor 130 again. After receiving the signal, the processor 130 records the current angle again. The processor 130 calculates the middle value of the two measured distribution angles, and the hole center is located on the midline of the two measured angles, thereby obtaining the hole center, which is convenient for the subsequent automated alignment and locking of the head and tail plates and the end plates.

[0042] like Figure 3 As shown, in some embodiments, the workbench assembly 110 includes a rotating table 111 and a fixing fixture 112 . The fixing fixture 112 is installed on the rotating table 111 , and the fixing fixture 112 is used to clamp the workpiece 200 to be measured.

[0043] Exemplarily, the rotating table 111 may be a pneumatic rotating table, and the fixing fixture 112 may be fixed to the turntable of the rotating table 111 by bolts. The fixing fixture 112 clamps the head and tail plates, and the rotating table 111 drives the head and tail plates to rotate under the drive of the cylinder, so as to facilitate the measurement of the hole distribution angle.

[0044] like Figure 3 As shown, in some embodiments, the fixing fixture 112 includes a fixing seat 1121, a slide rail 1122 and a clamp block 1123.

[0045] For example, the fixing seat 1121 is a truncated cone structure, and the slide rails 1122 and the clamping blocks 1123 are arranged in a one-to-one correspondence. The number of the slide rails 1122 and the clamping blocks 1123 can be two, three, four, five, six, etc., respectively, and can be reasonably selected according to the size and clamping strength of the head and tail plates.

[0046] In this embodiment, there can be six slide rails 1122 and six clamping blocks 1123. Each slide rail 1122 is installed along different radial directions of the fixing seat 1121, and the angles of two adjacent slide rails 1122 are the same, so that the clamping blocks 1123 are arranged opposite to each other in pairs to stably clamp the sides of the head and tail plates.

[0047] like Figure 3 As shown, in some embodiments, the fixing seat 1121 is provided with a plurality of slide grooves 11211 distributed along the radial direction of the fixing seat, and the slide rails 1122 are slidably disposed in the slide grooves 11211 .

[0048] Exemplarily, the number of the slide grooves 11211 can be two, three, four, five, six, etc., and the specific number can be selected according to actual conditions.

[0049] In this embodiment, the number of the slide grooves 11211 can be six. The slide rails 1122 are arranged one by one with the slide grooves 11211. The bottom of the slide rail 1122 is installed in the slide groove 11211 and can slide along the slide groove 11211 under the action of the driving structure to drive the clamping block 1123 to close or open to the axis of the fixing seat 1121.

[0050] In other embodiments, the fixing fixture 112 may be a pneumatic chuck to achieve automatic clamping of the head and tail plates.

[0051] like Figure 4 As shown, in some embodiments, a boss 11231 is provided at one end of the clamping block 1123 away from the axis of the fixing seat 1121 , and the plurality of bosses 11231 are used to respectively abut against the sides of the workpiece 200 to be measured.

[0052] Exemplarily, a side of the boss 11231 close to the head and tail plates is provided with an arc surface, so that the side of the head and tail plates fits with the arc surface of the boss 11231, thereby strengthening the limiting effect on the head and tail plates.

[0053] like Figure 1 As shown, in some embodiments, the detection assembly 120 further includes a mounting bracket 122 , and a measuring member 121 is mounted on a side of the mounting bracket 122 close to the workbench assembly 110 .

[0055] like Figure 5As shown, in some embodiments, the mounting bracket 122 includes a slide 1221 and a column 1222 , the column 1222 is vertically mounted on the slide 1221 , and the measuring piece 121 is mounted on the column 1222 .

[0056] Exemplarily, the slide 1221 is placed horizontally, the column 1222 is vertically installed on the slide 1221, and the measuring piece 121 is fixed to the side of the column 1222 close to the workbench assembly 110. The slide 1221 can drive the column 1222 and the measuring piece 121 to adjust their positions to adjust the measurement position.

[0057] Combination Figure 1 and Figure 5 As shown, in some embodiments, the hole position identification device 100 further includes a base 140 , and the base 140 is installed with a workbench assembly 110 and a detection assembly 120 .

[0058] For example, the base 140 may be a workpiece welded from a plurality of metal plates, and the base 140 may be fixed to a work surface or the ground by bolts. The mounting bracket 122 and the workbench are respectively mounted on both sides of the base 140 to achieve overall transport and assembly of the device and improve the compactness of the structure.
