Description

Technical Field

[0001] The utility model relates to the technical field of numerical control side hole machines, in particular to a positioning mechanism of a numerical control side hole machine. Background Art

[0002] During the wood processing process, especially the processing of wooden boards, countersunk holes need to be drilled on the wooden boards to install expansion bolts and eccentric pieces, and side holes need to be drilled on the side walls of the countersunk holes for installing eccentric pieces to install bolts. Side holes are usually drilled using a side hole machine. When drilling holes, in order to prevent the board from moving and causing deviation in the holes, a positioning mechanism is needed to fix the board.

[0003] The positioning mechanism of the existing CNC side hole machine is usually composed of multiple cylinders. A slide rail is installed on the gantry above the CNC side hole machine. The multiple cylinders are slidably connected to the slide rail and can be fixed by a fixing component. The end of the piston rod of the cylinder is fixedly connected to a positioning block. By placing the plate on the table of the CNC side hole machine, the cylinder extends, causing the positioning block to press on the top of the plate, thereby positioning the plate and ensuring that the plate does not move when punching holes on the side of the plate. However, the positioning mechanism of the existing CNC side hole machine still has the following defects when in use:

[0004] Since multiple cylinders are slidably connected in a slide rail, and the cylinders are wearing parts, when a cylinder in the middle is damaged, the cylinders at the edge need to be slid out of the slide groove first before the cylinder in the middle can be disassembled. Therefore, disassembly during maintenance is time-consuming and labor-intensive, and is inconvenient for maintenance. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] To this end, one purpose of the present invention is to propose a positioning mechanism for a CNC side hole machine, aiming to solve the problem that the positioning mechanism of the CNC side hole machine in the prior art is time-consuming and labor-intensive to disassemble and inconvenient to maintain.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a positioning mechanism of a CNC side hole machine, including a slide rail, a connecting block and a cylinder, the top of the connecting block is fixedly connected with a protrusion, the top of the protrusion is fixedly connected with a limiting block, the limiting block is slidably connected in the slide rail, a slide groove is provided on one side of the connecting block, the top of the cylinder is fixedly connected with a slider, the slider is slidably connected in the slide groove, and the piston rod end of the cylinder is fixedly connected with a positioning block.

[0008] Preferably, any of the above solutions has a V-shaped connection block, and the sliding groove is provided on the inner side of the V-shaped connection block, so that the slider does not need a fixed structure, thereby further facilitating assembly and disassembly.

[0009] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0010] 1. During use, if a cylinder in the middle is damaged and needs to be disassembled for repair or replacement, you only need to pull the slider out of the slide slot without removing the cylinder on the edge. This makes disassembly easy, saving time and effort, and facilitating later repairs.

[0011] 2. By setting the connecting block into a V shape, its bottom surface is tilted, so that the slide is also tilted. After the slider on the cylinder is slid and connected to the inside of the slide, the cylinder and the slider are also tilted, so the slider will not slide out of the slide. When installing the cylinder, you only need to insert the slider into the slide, and no other fixing structure is required. The installation operation is simple and convenient.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0021] The utility model provides a positioning mechanism for a numerically controlled side hole machine.

[0022] Example 1:

[0023] like Figure 1-4 As shown, it includes a slide rail 1, a connecting block 2 and a cylinder 3. The top of the connecting block 2 is fixedly connected with a protrusion 22, and the top of the protrusion 22 is fixedly connected with a limit block 23. The limit block 23 is slidably connected to the slide rail 1. The setting of the protrusion 22 makes the connecting block 2 located below the slide rail 1. Threaded holes 24 are provided on both sides of the bottom of the limit block 23. The internal threads of the threaded holes 24 are connected with positioning bolts 4. By rotating the positioning bolts 4, the top of the positioning bolts 4 are in contact with the inner wall of the slide rail 1, so that the limit block 23 can be fixed. The end of the positioning bolt 4 is interference-fitted with a rotating rod 41. A slide groove 21 is provided on one side of the connecting block 2. The top of the cylinder 3 is fixedly connected with a slider 31, and the slider 31 is slidably connected in the slide groove 21. When disassembling the damaged cylinder 3, it is only necessary to slide the slider 31 on the cylinder 3 out of the slide groove 21. The piston rod end of the cylinder 3 is fixedly connected with the positioning block 32. Figure 4 As shown, place the plate on the workbench of the CNC side hole machine, then extend the cylinder 3 and lower the positioning block 32 to press down and fix the plate. The bottom end of the positioning block 32 is fixedly connected with an anti-slip pad 33 to increase the friction force, thereby fixing the plate more securely.

[0024] Preferably, Figure 3 As shown, the outer surface of the cylinder 3 is fixedly connected to a positioning sleeve 34, the positioning sleeve 34 is fixed on the outer wall of the cylinder 3, and the interior of the positioning sleeve 34 is slidably connected to a guide rod 35, one end of the guide rod 35 is fixedly connected to the positioning block 32. When the cylinder 3 is extended or retracted, the piston rod drives the positioning block 32 to move, and the guide rod 35 slides inside the positioning sleeve 34. The guide rod 35 can assist the piston rod of the cylinder 3 in supporting the positioning block 32.

[0025] Example 2:

[0026] like Figure 1 、 Figure 2 and Figure 4As shown, based on the first embodiment, the shape of the connecting block 2 is V-shaped, and the bottom surface of the V-shaped connecting block 2 is inclined, so that after the cylinder 3 is installed, the cylinder 3 is inclined, as shown in FIG. Figure 4 As shown, the cylinder 3 is tilted toward the punching mechanism of the CNC side hole machine, and the slide groove 21 is opened on the inner side of the V-shaped connecting block 2, so that the slider 31 will not slide out of the slide groove 21, and therefore no other fixing structure is required to fix the slider 31.

[0027] The working principle of the present invention is as follows: when in use, the slide rail 1 is fixedly connected to the bottom of the gantry above the CNC side hole machine, and multiple cylinders 3 are slidably connected to the slide rail 1 through the limit block 23 on the connecting block 2. The position of the cylinder 3 can be adjusted by sliding the lower fastener 23. After adjusting to the appropriate position, the positioning bolt 4 is rotated by the rotating rod 41 so that the top of the positioning bolt 4 contacts the inner wall of the slide rail 1, thereby fixing the limit block 23 and achieving the purpose of positioning the cylinder 3. During use, if a cylinder 3 in the middle is damaged and needs to be disassembled for maintenance or replacement, it is only necessary to pull out the slider 31 from the slide groove 21, and there is no need to disassemble the cylinder 3 at the edge, so the purpose of easy disassembly can be achieved.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. During use, if a cylinder 3 in the middle is damaged and needs to be disassembled for repair or replacement, it is only necessary to pull out the slider 31 from the slide groove 21, and there is no need to disassemble the cylinder 3 at the edge. Therefore, the purpose of easy disassembly can be achieved, thereby saving time and effort and facilitating later maintenance.

[0030] 2. By setting the connecting block 2 into a V shape, its bottom surface is inclined, so that the slide groove 21 is also inclined. After the slider 31 on the cylinder 3 is slidably connected to the inside of the slide groove 21, the cylinder 3 and the slider 31 are also inclined, so the slider 31 will not slide out of the slide groove 21. Therefore, when installing the cylinder 3, it is only necessary to insert the slider 31 into the slide groove 21, and no other fixing structure is required. The installation operation is simple and convenient.
