Positioning module 200 is provided with two, wherein one positioning module 200 and first measuring piece 110 along first scale 111 sliding connection, and another positioning module 200 and second measuring piece 120 along second scale 121 sliding connection, and positioning module 200 selectively positions in the hole that has been made, can go to the third hole in the case of two holes in space, and the hole leading device is widely applicable, and can be used for a variety of complex working conditions auxiliary positioning hole making, the simple structure appearance, the small volume is occupied, and the influence of zero, assembly appearance and state is less, and the use method is simple, need not additional fastener, avoid the damage to product, and the economic benefit is excellent.
[0035] Specifically, hole leading module 100 further includes connecting sleeve 130, connecting sleeve 130 can be machined, and first measuring piece 110 and second measuring piece 120 are rotatably sleeved in connecting sleeve 130, and hole leading part 101 is embedded into connecting sleeve 130, and hole leading part 101 can be a drill sleeve matched with a drill bit, facilitating hole leading. The drill bit is inserted into the drill sleeve of hole leading part 101, and a matched hole can be obtained on the part to be drilled, and each component part can be machined, so that the manufacturing and assembly process is simple, and the production cost is low.
[0036] Further, in order to enhance the structural stability of the lead-through device, a limiting flange 131 is arranged at one end of the connecting sleeve 130, which is used to prevent the first measuring member 110 and the second measuring member 120 from slipping off from one end of the connecting sleeve 130. Optionally, the lead-through module 100 should also include a locking ring 140, which is selectively sleeved at the other end of the connecting sleeve 130, used to prevent the first measuring member 110 and the second measuring member 120 from slipping off from the other end of the connecting sleeve 130. The above two methods of adding the limiting flange 131 or adding the locking ring 140 can both fix the first measuring member 110, the second measuring member 120 and the connecting sleeve 130. When the first measuring member 110 and the second measuring member 120 are sleeved and installed on the connecting sleeve 130 in sequence, the locking ring 140 is tightened to make the connecting sleeve 130 and the locking ring 140 sandwich the first measuring member 110 and the second measuring member 120, while not affecting the rotation of the first measuring member 110 and the second measuring member 120 on the connecting sleeve 130
[0037] In the present embodiment, each positioning module 200 includes a set of corresponding positioning sleeve 210 and hole position pin 220. Each positioning module 200 is arranged in the same way on the first measuring member 110 and the second measuring member 120, one positioning sleeve 210 is sleeved on the first measuring member 110, and the other positioning sleeve 210 is sleeved on the second measuring member 120. One end of the hole position pin 220 is connected with the positioning sleeve 210, which can slide along the length extension direction of the first measuring member 110 or the second measuring member 120, and record the position of the positioning module 200 by the first scale 111 or the second scale 121 on it. The other end of the hole position pin 220 can be inserted into the drilled hole to position the positioning module 200, i.e. to position the drilled hole. After the positioning module 200 is assembled, the two hole position pins 220 are inserted into the two drilled holes, which can record the planar positions of the two drilled holes, and can facilitate the determination of the position of the third hole, i.e. the to-be-drilled hole, in some narrow space.
[0038] It can be understood that the two hole position pins 220 are arranged in parallel, which can more accurately correspond to the two prepared holes, and the axial direction of the hole position pin 220 is parallel to the rotation shafts of the first measuring member 110 and the second measuring member 120. By moving the two positioning sleeves 210, the distance between the third hole and the two prepared holes is determined, and positioning is completed. In some specific implementation cases, the two prepared holes and the pre-set to-be-punched hole are arranged in parallel, and the punching position can be more accurately determined. In special cases, there is a non-coplanar or non-parallel relationship between the prepared hole and the to-be-punched hole, and the positioning module 200 still needs to be improved, for example, the hole position pin 220 can rotate around the outer periphery of the positioning sleeve 210 in addition to being able to slide along the scale direction with the first measuring member 110 and the second measuring member 120. The two hole position pins 220 can form a certain angle in the vertical plane to adapt to the possibility of more prepared holes.
[0039] Optionally, the hole position pin 220 is arranged in an extendable structure along the axial direction, which is used to change the axial length of the hole position pin 220, so as to ensure that the hole position pin 220 can still be inserted into the prepared hole for positioning when the hole depths of the prepared holes are different or the heights of the table surfaces are different. At the same time, the extendable hole position pin 220 can improve the storage performance of the hole guiding device and further expand the application range of the hole guiding device, so that the positioning module 200 can pass through some narrow passages or passages with gully undulations.
[0040] Specifically, each positioning module 200 includes a locking portion 230, one of which is selectively connected with the first measuring member 110, and the other of which is selectively connected with the second measuring member 120. The locking portion 230 is used to fasten the positioning module 200 to the first measuring member 110 and the second measuring member 120 of the hole guiding module 100. When the hole position pin 220 is moved to the correct position on the first measuring member 110 or the second measuring member 120, the locking portion 230 can be tightened to fix the position of the positioning sleeve 210. The cooperation between the positioning sleeve 210 and the two prepared holes ensures that the hole guiding device does not move and the positioning is accurate. For example, the locking portion 230 can be controlled by electromagnetic means to lock and unlock, which avoids the situation that the position of some prepared holes is not convenient for the hands of the staff to operate.
[0041] Further, the tail end of the first measuring member 110 and the tail end of the second measuring member 120 are respectively provided with a limiting portion, which can block the positioning sleeve 210 from slipping off the hole guiding module 100, and ensure the use stability and structural integrity of the hole guiding device.
[0042] In the embodiment, the hole site pin 220 is used for inserting the prepared hole, one end of which is provided with a tapered head 221, which can adapt to prepared holes of different diameters, and under the premise of ensuring the structural strength of the hole site pin 220, facilitates the plugging and positioning of the hole site pin 220 and the prepared hole, and can also accurately position the prepared hole with too small diameter, thereby expanding the application range of the hole guiding device. In another embodiment, multiple specifications of the hole site pin 220 can be provided to better match prepared holes of multiple specifications, and the hole site pin 220 and the positioning sleeve 210 are detachably connected, which facilitates quick replacement, the size of the hole site pin 220 is comparable to that of the prepared hole, and the positioning and hole guiding accuracy is further improved.
[0043] Exemplarily, as shown in FIG. 1, Figure 5 The relative rotatable angle of the first measuring member 110 and the second measuring member 120 is greater than 180°, the flexibility of the hole guiding device is higher, and the hole guiding device can be applied to more hole guiding scenes, and is not limited to the form of positioning a third hole through two prepared holes. For different use scenes, the first measuring member 110 and the second measuring member 120 can be two connecting rods with scales with consistent or inconsistent lengths, and each component of the hole guiding device is detachably connected, thereby improving the assembly interchangeability.
[0044] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, various obvious changes, readjustments and replacements can be made without departing from the protection scope of the utility model. Here, it is unnecessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
