In actual production, these holes need to be inspected to check for positional deviations, preventing inconvenience during assembly. Current technology typically uses coordinate measuring machines (CMMs) for individual hole position inspection, requiring continuous manual adjustment of the profile position. This process is cumbersome, time-consuming, inefficient, and costly. Utility Model Content

[0026] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this application proposes a multi-hole position measurement device, which includes a base plate 1. A plurality of limiting blocks 11 are spaced apart on the base plate 1, forming a placement area 12 for placing a workpiece. A clamping mechanism 2 is circumferentially arranged on the base plate 1 corresponding to the placement area 12 to limit the horizontal and vertical displacement of the workpiece, clamping it onto the base plate 1 for measurement. A plurality of hole position measurement mechanisms 3 are arranged on both sides and below the placement area 12 on the base plate 1 to measure the position of the holes to be measured on the end faces and bottom surface of the workpiece placed within the placement area 12. This enables simultaneous multi-hole position measurement, effectively improving work efficiency.

[0028] like Figure 1-2As shown, the hole position detection mechanism 3 includes a mounting plate 32, several detection components 31 disposed on the mounting plate 32, and a drive component 33 that drives the detection components 31 to move closer to the workpiece within the placement area 12. The drive component 33 includes a transverse slide rail 331 and a transverse cylinder 332. One end of the transverse slide rail 331 extends towards the placement area 12. The mounting plate 32 is slidably disposed on the transverse slide rail 331 via a slider. The mounting plate 32 is connected to the output end of the transverse cylinder 332. The transverse cylinder 332 drives the mounting plate 32 to reciprocate along the transverse slide rail 331, thereby enabling the detection components 31 on the mounting plate 32 to perform positional detection. In a specific embodiment, the arrangement of the detection components 31 on the mounting plate 32 and the placement position of the hole position detection mechanism 3 can be adaptively adjusted according to the opening position of the hole to be detected on the workpiece.

[0029] like Figure 1-3 As shown, the detection component 31 includes a detection shaft 311. A detection part 3111 is formed at one end of the detection shaft 311 near the placement interval 12. The drive component 33 drives the detection shaft 3111 to move, thereby inserting the detection part 3111 into the hole to be detected in the workpiece. Preferably, the detection part 3111 is a uniform columnar structure, and its cross-sectional shape is designed to mimic the shape of the hole to be detected in the workpiece. Specifically, it can be circular, polygonal, etc., so that the detection part 3111 can be smoothly inserted into the hole to be detected, thus confirming the accurate position of the hole to be detected in the workpiece. If the detection part 3111 cannot be inserted, it indicates that there is a deviation in the position of the hole to be detected.

[0030] like Figure 1-3 As shown, a movable part 3112 is formed at the end of the detection shaft 311 away from the detection part 3111. The movable part 3112 movably passes through the mounting plate 32. A limiting part 3113 is provided between the movable part 3112 and the detection part 3111. A locking block 313 is disposed at the end of the movable part 3112 away from the limiting part 3113. The locking block 313 is used to prevent the detection shaft 311 from detaching from the mounting plate 32. The limiting part 3113 and the locking block 313 limit the movement range of the detection shaft 311. Preferably, the locking block 313 and the detection shaft 311 can be connected by a threaded connection for easy disassembly and assembly. A return spring 312 is circumferentially sleeved on the movable part 3112. The two ends of the return spring 312 are restricted between the mounting plate 32 and the limiting part 3113. The detection assembly also includes a sensor 314, which is fixed to the mounting plate 32 by a support plate and is used to detect the displacement of the detection shaft 311. Preferably, in this embodiment, the sensor 314 is disposed on one side of the locking block 313 to specifically detect the displacement of the locking block 313.

[0031] The specific detection process is as follows: the drive assembly 33 drives the mounting plate 32 to move towards the installation interval 12. If the hole to be tested is not aligned, the detection part 3111 of the detection shaft 311 abuts against the side wall of the workpiece, the detection shaft 3111 moves relative to the mounting plate 32, the return spring 312 is compressed, the sensor 314 detects the displacement of the locking block 313 and issues a prompt to remind that the position of the detection hole is inaccurate. If the hole to be tested is aligned, the detection part 3111 of the detection shaft 311 passes through the hole to be tested in the workpiece. After the detection is completed, the mounting plate 32 drives the detection shaft 311 to retract. After the detection shaft 311 is no longer subjected to external abutment, the limiting part 3113 returns to its original position under the elastic action of the return spring 312.

[0032] like Figure 1 and 4 As shown, the clamping mechanism 2 includes a clamping assembly 21 for limiting the horizontal displacement of the workpiece and a pressing assembly 22 for limiting the vertical displacement of the workpiece. The clamping assembly 21 includes side abutments 211 and clamping members disposed on opposite sides of the placement area 12. The clamping members include a clamping plate 212 and a clamping cylinder 213 that drives the clamping plate 212 to move closer to and further away from the side abutments 211. When the workpiece is placed within the placement area 12, the side abutments 211 abut against one side of the workpiece, and the clamping cylinder 213 drives the clamping plate 212 to clamp the workpiece on the other side, thereby confining the workpiece between the side abutments 211 and the clamping plate 212.

[0033] like Figure 1 and 5 As shown, the pressing assembly 22 includes a lifting cylinder 221 mounted on the base plate 1. The output end of the lifting cylinder 221 faces upward and the end of the push rod is rotatably connected to a pressing connecting rod 222. An upright pole 223 is mounted on the side of the lifting cylinder 221 near the placement area 12. A first connecting rod 224 is rotatably connected to the upper end of the pole 223. The other end of the first connecting rod 224 is rotatably connected to the middle section of the pressing connecting rod 222. The end of the pressing connecting rod 222 away from the lifting cylinder 221 extends to the top of the placement area 12 and is equipped with a pressing head 225.

[0034] like Figure 1 As shown, a number of positioning pads 13 are provided on the base plate 1 within the corresponding placement area 12. The positioning pads 13 are provided with raised positioning posts 131. The distribution of the positioning posts 131 is adapted to the positioning holes on the workpiece to ensure accurate placement of the workpiece.
