[0002] Multi-hole drilling equipment is a highly efficient drilling tool that can process multiple holes at the same time. The working principle of multi-hole drilling equipment is to drill holes in the workpiece simultaneously or sequentially using multiple drill bits.

[0003] The reference patent title is: A multi-hole synchronous drilling machine device (patent publication number: CN212526112U). Through an electric push rod, the position of the drilling motor can be adjusted by the first U-shaped frame, the second U-shaped frame and other equipment, so that the drilling motor can drive the drill bit to drill the parts. By installing multiple sets of second U-shaped frames on the crossbar, multiple sets of drilling motors can be installed. A support plate is set to place the structure to be drilled, so as to meet the requirements of multi-hole synchronous drilling.

[0004] However, the following problems exist when implementing the above technical solutions: During use, the position of the drilling motor can be adjusted, making it difficult to quickly locate the position of the structure to be drilled; there is a certain distance between the drilling motor and the support plate, and the position of the drilling motor can be quickly changed by changing the position of the second U-shaped frame. After the position of the drilling motor is changed, it takes a long time to adjust and locate the structure to be drilled. The adjustment steps for the placement of the structure to be drilled are cumbersome and time-consuming.

[0005] Therefore, this utility model proposes a multi-hole drilling device. Utility Model Content

To this end, this invention proposes a multi-hole drilling device that solves the problem that, after adjusting the position of the drilling motor inside existing multi-hole drilling devices, it is difficult to quickly locate the adjusted drilling position, requiring a long time to determine the placement of the structure to be drilled.

[0007] To achieve the above objectives, a multi-hole drilling device is provided according to an embodiment of the first aspect of this utility model, comprising a support plate and a plurality of sliding frames. The support plate is fixedly disposed on the surface of the machine body, and the sliding frames are all slidably disposed on the surface of the machine body. A driving mechanism is provided between the support plate and the sliding frames, the driving mechanism comprising:

[0008] A number of locking blocks are slidably disposed inside the support plate; the number of locking blocks is the same as the number of sliding frames; each locking block has a rotatably connected drive rod on its surface, and a ring spring is fixedly connected between the drive rod and the locking block; each locking block has a fitting groove on its surface, and the fitting groove is adapted to the drive rod.

[0010] Two locking rods are slidably disposed inside the sliding frame, and the two locking rods are symmetrically arranged relative to the telescopic rod. Each locking rod is fixedly connected to the sliding frame with a locking spring.

[0011] Optionally, the limiting component includes a limiting block slidably disposed on the surface of the drive rod, and the surface of the telescopic rod is provided with a sliding groove, wherein the limiting block and the sliding groove are adapted to each other.

[0012] Optionally, a limiting groove is formed on the surface of the driving rod, the limiting block is adapted to the limiting groove, and a limiting spring is fixedly connected between the limiting block and the limiting groove.

[0013] Optionally, a crossbar is slidably connected to the surface of the limiting block, and a vertical groove is formed on the surface of the driving rod.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1-7 As shown, a multi-hole drilling device includes a support plate 1 and several sliding frames 2. The support plate 1 is fixedly mounted on the surface of the machine body, and the sliding frames 2 are all slidably mounted on the surface of the machine body. A drilling motor is fixed to the side of each sliding frame 2 near the support plate 1. A driving mechanism is provided between the support plate 1 and the sliding frames 2. The driving mechanism includes:

[0032] A plurality of locking blocks 31 are slidably disposed inside the support plate 1; the number of locking blocks 31 is the same as the number of sliding frames 2.

[0033] A plurality of driving rods 32 are rotatably mounted on the surface of the locking block 31. A ring spring 33 is fixedly connected between the driving rod 32 and the locking block 31. The surface of the locking block 31 is provided with a fitting groove 34, which is adapted to the driving rod 32. When the ring spring 33 is in its natural state, the locking block 31 fits into the fitting groove 34. Furthermore, there are rotatable protruding driving rods 32 on the surface of the locking block 31. By pulling the driving rods 32, the locking block 31 can be slid. When the structure to be drilled is placed on the surface of the locking block 31, the driving rods 32 can fit into the surface of the locking block 31 without affecting the placement space of the structure to be drilled.

[0034] A plurality of telescopic rods 35 are provided, each of which is detachably connected to the interior of the sliding frame 2. The telescopic rods 35 are slidably connected to the interior of the driving rod 32. A limiting component is provided between the telescopic rods 35 and the driving rod 32 to restrict their positions.

[0035] Two locking rods 36 are slidably disposed inside the sliding frame 2, and the two locking rods 36 are symmetrically arranged relative to the telescopic rod 35. Each locking rod 36 is fixedly connected to the sliding frame 2 by a locking spring 37. When the locking spring 37 is in its natural state, the two locking rods 36 are in contact. The stiffness coefficient of the locking spring 37 is greater than that of the annular spring 33. When the locking rod 36 is in contact with the telescopic rod 35, the telescopic rod 35 is perpendicular to the sliding frame 2 and the locking block 31. Due to the telescopic... The telescopic rod 35 is slidably connected to the driving rod 32, and the driving rod 32 is also perpendicular to the sliding frame 2 and the locking block 31. At this time, the ring spring 33 is not in a natural state. However, since the spring constant of the locking spring 37 is greater than the spring constant of the ring spring 33, the telescopic rod 35 and the driving rod 32 will not change their positions on their own under the action of no external force. This ensures that when the sliding frame 2 drives the drilling motor to move, the telescopic rod 35 and the driving rod 32 can make the locking block 31 move synchronously, ensuring the position between the locking block 31 and the drilling motor.

[0036] In practical application, this multi-hole drilling equipment has the same number of locking blocks 31 as the sliding frame 2 inside the bearing plate 1. The locking blocks 31 further ensure the alignment of the material to be drilled with the drilling motor position inside the sliding frame 2. A sliding telescopic rod 35 and a rotating drive rod 32 are set between the sliding frame 2 and the locking blocks 31. One end of the telescopic rod 35 is detachably fixed to the sliding frame 2, and the telescopic rod 35 and the drive rod 32 are slidably connected. Thus, the sliding frame 2 and the locking blocks 31 can be relatively fixed in position through the telescopic rod 35 and the drive rod 32. When the sliding frame 2 drives the drilling motor to slide, it can simultaneously drive the locking blocks 31 to slide, ensuring that the material to be drilled corresponds to the drilling motor position after being placed in the locking blocks 31.

[0037] In some specific implementations, the surface of the locking block 31 is threaded with a fixing rod 61, and the surface of the bearing plate 1 is provided with a moving groove 62, which is adapted to the fixing rod 61; the fixing rod 61 can be rotated to fit against the surface of the moving groove 62, thereby increasing the contact area between the fixing rod 61 and the surface of the bearing plate 1, and thus fixing the position of the locking block 31.

[0038] In some specific implementations, the telescopic rod 35 includes a connecting rod and a connecting shaft. The connecting shaft is slidably connected to the inside of the connecting rod. The connecting rod and the driving rod 32 are slidably connected. A restoring spring is fixedly connected between the connecting rod and the driving rod 32 and the connecting shaft and the connecting rod. A limit component is also provided between the connecting rod and the connecting shaft to limit their position. By splitting the telescopic rod 35 into the connecting rod and the connecting shaft, the length of the telescopic rod 35 is further extended, thereby ensuring that the telescopic rod 35 can slide completely into the inside of the driving rod 32, and that the other end of the telescopic rod 35 can contact the sliding frame 2.

[0039] In some specific embodiments, the limiting component includes a limiting block 41 slidably disposed on the surface of the driving rod 32, a sliding groove 42 formed on the surface of the telescopic rod 35, the limiting block 41 and the sliding groove 42 being adapted to each other, a limiting groove 43 formed on the surface of the driving rod 32, the limiting block 41 and the limiting groove 43 being adapted to each other, and a limiting spring 44 being fixedly connected between the limiting block 41 and the limiting groove 43; when the limiting spring 44 is in its natural state, the limiting block 41 is in contact with the sliding groove 42.

[0040] In a further embodiment, a crossbar 45 is slidably connected to the surface of the limiting block 41, and a vertical groove 46 is formed on the surface of the driving rod 32. The vertical groove 46 communicates with the limiting groove 43, and the depth of the vertical groove 46 is less than the depth of the limiting groove 43. The crossbar 45 is adapted to the vertical groove 46. A sliding crossbar 45 is provided on the surface of the limiting block 41, and a vertical groove 46 adapted to the crossbar 45 is provided. Thus, after the limiting block 41 slides and disengages from the sliding groove 42, the crossbar 45 can be slid to insert into the vertical groove 46, restricting the position of the limiting block 41, thereby ensuring that the limiting block 41 will not reset when the telescopic rod 35 slides.

[0041] In some specific implementations, a connecting strap 51 is fixedly connected between the two locking rods 36, and a transfer column 52 is fixedly connected inside the sliding frame 2. The distance between the transfer column 52 and the two locking rods 36 is different, and the difference between the two distances is equal to the distance between the two locking rods 36. The connecting strap 51 is slidably connected to the surface of the transfer column 52.

[0042] In a further embodiment, an operating rod 53 is rotatably connected to the surface of the locking rod 36. The operating rod 53 has a T-shaped cross-section. An operating groove 54 is provided on the surface of the sliding frame 2. The operating groove 54 has a lever-shaped cross-section. The operating rod 53 is adapted to the operating groove 54.

[0043] In some specific implementations, two contact blocks are slidably connected inside the locking block 31. The two contact blocks are symmetrically arranged, and the two opposite surfaces of the contact blocks are in contact with the locking block 31. A movable spring is fixedly connected between the contact blocks and the locking block 31.

[0044] The working principle of this utility model is as follows: When the drilling motor needs to be moved, firstly rotate the drive rod 32 to make the drive rod 32 perpendicular to the locking block 31. Then slide the limiting block 41 away from the telescopic rod 35 to make the surface of the limiting block 41 disengage from the sliding groove 42. When the limiting block 41 slides to the position of the vertical groove 46, slide the horizontal bar 45 to make the horizontal bar 45 insert into the vertical groove 46. Then slide the telescopic rod 35 to make one end of the telescopic rod 35 contact the surface of the sliding frame 2. Then rotate the operating rod 53 to make the operating rod 53 slide inside the operating groove 54. Press the telescopic rod 35 to make the telescopic rod 35 squeeze the locking rod 36 and move it into the sliding frame 2. Then reset the operating rod 53 to restrict the locking rod 36 from sliding again, fix the position of the telescopic rod 35, the drive rod 32 and the locking block 31, and then move the sliding block to drive the drilling motor to slide, thereby driving the locking block 31 to slide.

[0045] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
