[0002] Bench-mounted drilling machines are a widely used type of drilling equipment in the machining of mechanical parts. A drilling machine is a machine tool that mainly uses a drill bit to machine holes in a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. It can drill through holes and blind holes. By changing special drill bits, it can also perform reaming, boring, or tapping operations.
[0003] Existing bench drills can generally only machine one hole in a part. In order to improve work efficiency, bench drills are equipped with multi-spindle heads. However, a bench drill can generally only be equipped with one multi-spindle head, which means that the bench drill can only perform one drilling operation, making it inconvenient to use the bench drill.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figures 1 to 6As shown, this utility model can be implemented through the following embodiments: A replaceable bench drill multi-spindle head 3 device includes a drill body 1, a fixing fixture and a multi-spindle head 3. The drill body 1 is provided with an installation rod 4. The top of the multi-spindle head 3 is provided with a fixing part 31. A connecting rod 311 is provided inside the fixing part 31. Limiting parts 32 are provided at both ends of the fixing part 31. A slider 33 is provided on the inner wall of the limiting part 32. A fixing rod 5 is provided outside the limiting part 32. A moving plate 6 is provided on the fixing fixture. A cylinder 61 is connected to the moving plate 6.
[0022] Mounting rod 4 is used to mate with fixing part 31 at the top of multi-spindle 3. Connecting rod 311 is used to insert into mounting rod 4 so that power can be transmitted to multi-spindle 3 through connecting rod 311. Limiting part 32 is used to install fixing rod 5. Fixing rod 5 passes through fixing part 31 and mounting rod 4 to fix multi-spindle 3 and mounting rod 4. Moving plate 6 is used to fix and limit parts to ensure correct drilling position.
[0023] like Figure 1 As shown, the fixture has a mounting groove 21, and a fixing block 22 is installed in the mounting groove 21. The fixing block 22 is used to place the part to be processed. The detachable fixing block 22 facilitates the use of the multi-spindle head 3 to change the position and diameter of the hole to be drilled.
[0024] like Figure 1 and Figure 6 As shown, the fixing block 22 has a positioning hole 222 and a through hole 221. A positioning rod 7 is installed on the positioning hole 222. The positioning hole 222 works in conjunction with the installation of the positioning rod 7 to fix small parts and prevent the moving plate 6 from getting too close and affecting the feed of the multi-spindle 3. The through hole 221 is used to allow the drill bit to extend into it after the multi-spindle 3 has completed drilling, preventing the drill bit from contacting the clamp and causing damage.
[0025] like Figure 4 As shown, a limiting plate 71 is provided on the positioning rod 7. The limiting plate 71 is used to cooperate with the fixing block 22 and the positioning rod 7 to clamp and fix the small parts on the fixing fixture, which facilitates drilling.
[0026] like Figure 1 and Figure 6 As shown, positioning blocks 223 are provided on both sides of the fixing block 22, and countersunk bolts 8 pass through the positioning blocks 223 and are inserted into the mounting grooves 21. The positioning blocks 223 are used to cooperate with the fixing block 22 for installation, and the countersunk bolt holes are used to fix the fixing block 22 and the mounting grooves 21 together.
[0027] As shown in Figure 5, the fixing rod 5 is provided with a thread 51. The thread 51 is used to connect the fixing rod 5 and the mounting rod 4, thereby fixing the multi-axis device 3 and the mounting rod 4 together.
[0028] like Figure 3As shown, the mounting rod 4 is provided with a sliding groove 41, and a fixing hole 42 is provided in the sliding groove 41. The sliding groove 41 is used to cooperate with the slider 33 to prevent the multi-axis device 3 from falling directly after the fixing rod 5 is removed, which would cause the multi-axis device 3 to collide with the fixing clamp or require two people to disassemble, making it easy for one person to replace; the fixing hole 42 is used to provide a position for the fixing rod 5 to connect with the mounting rod 4, so that the multi-axis device 3 is fixedly connected to the mounting rod 4.
[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0030] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
