Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a drilling device for hardware parts. Background Technology

[0002] A drilling machine is a general term for machinery and equipment that uses a tool harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. It is also called a drill, hole punch, or through-hole drill, etc. It achieves the desired effect by drilling holes in hardware parts. Current drilling machines are usually equipped with only one drill rod; when different diameter through holes need to be drilled on hardware parts, the drill rod needs to be manually disassembled and replaced.

[0003] For example, a high-precision drilling device for hardware parts production disclosed in Chinese patent literature (publication number: CN212070511U) can be installed by mounting a drill bit in a slot. The drive block at one end of the drill bit is installed in the slot, the connecting tube is inserted into the sleeve, and the fixing bolt is used to fix the fixing block and the sleeve through the screw hole. The drive end of the motor is inserted into the slot in the drive block through the slot. This not only allows for quick disassembly and installation of the drill bit, internal maintenance and replacement, but also allows for the replacement of drill bits of different specifications, making it suitable for drilling more specifications.

[0004] However, in actual production, when a hardware part needs to have multiple through holes of different diameters drilled, the drill bit needs to be disassembled and replaced frequently. Each replacement requires the operator to find a suitable tool, such as a wrench, to loosen the fixing bolts, which not only greatly increases manual labor but also seriously affects the drilling efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for frequent drill bit replacements during the processing of hardware parts, which not only increases labor costs but also reduces drilling efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drilling device for hardware parts includes a processing table, a moving adjustment mechanism is provided above the processing table, and the moving adjustment mechanism includes a top plate. A symmetrically distributed servo electric cylinder is fixedly installed on the upper end of the processing table, and one end of the piston rod of each of the two servo electric cylinders is fixedly connected to the lower end of the top plate.

[0008] The top plate has a travel groove at its upper end, and a threaded block is slidably connected to the inner wall of the travel groove. A fixed bracket is fixedly connected to the lower end of the threaded block.

[0009] A switching mechanism is provided above the processing table, and the switching mechanism is located below the moving adjustment mechanism.

[0010] Preferably, a first servo motor is fixedly installed at the upper end of the top plate, and a lead screw is fixedly installed on the output shaft of the first servo motor through a coupling.

[0011] Preferably, the outer side of the lead screw is threaded to the inner wall of the threaded block, and a support block is rotatably connected to one end of the lead screw via a bearing. The lower end of the support block is fixedly connected to the upper end of the top plate.

[0012] Preferably, the switching mechanism includes an annular mounting block, the upper end of which is fixedly connected to the lower end of the fixed bracket, and a drive rod is rotatably connected to the inner wall of the annular mounting block via a bearing.

[0013] Preferably, a worm gear is fixedly sleeved on the upper end of the drive rod, and the lower end of the drive rod extends to the bottom of the annular mounting block and is fixedly connected to a cross mounting plate.

[0014] Preferably, a second servo motor arranged in a circular array is fixedly mounted on the upper end of the cross mounting plate, and a drill rod is fixedly mounted on the output shaft of the second servo motor via a coupling.

[0015] Preferably, one end of the drill rod passes through and extends below the cross mounting plate, and the lower end of the annular mounting block is provided with an annular groove, the inner wall of which is slidably connected with arc-shaped sliders distributed in an annular array.

[0016] Preferably, the lower end of the arc-shaped slider is fixedly connected to the upper end of the cross mounting plate, and a third servo motor is fixedly mounted on the upper end of the annular mounting block. The output shaft of the third servo motor is fixedly mounted with a worm gear through a coupling, and the outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the servo electric cylinder of the movable adjustment mechanism can precisely control the lifting and lowering of the top plate to adapt to hardware parts of different thicknesses and achieve precise adjustment of the drilling height. The first servo motor drives the lead screw, which drives the threaded block to slide in the stroke groove, so that the fixed bracket and the switching mechanism can move laterally, which facilitates precise positioning and drilling at different positions of the hardware parts. The switching mechanism is equipped with multiple drill rods, and the worm gear is driven by the third servo motor to mesh with the worm wheel, which drives the drive rod and the cross mounting plate to rotate. Different specifications of drill rods can be quickly switched without frequent manual disassembly and installation, reducing labor intensity and greatly improving drilling efficiency.

[0030] The movable adjustment mechanism includes a top plate 2. The upper end of the processing table 1 is fixedly mounted with symmetrically distributed servo electric cylinders 21 by bolts. One end of the piston rod of each of the two servo electric cylinders 21 is fixedly connected to the lower end of the top plate 2 by welding or bolt connection. This connection method can ensure that the servo electric cylinders 21 stably control the lifting and lowering of the top plate 2.

[0031] The top plate 2 has a travel groove 22 at its upper end. The inner wall of the travel groove 22 is connected to the threaded block 23 by a sliding fit, that is, the threaded block 23 can slide smoothly in the travel groove 22. The lower end of the threaded block 23 is fixedly connected to a fixed bracket 24 by welding or bolt connection.

[0032] The top plate 2 is fixedly mounted with a first servo motor 25 by bolts. The output shaft of the first servo motor 25 is fixedly connected to the lead screw 26 by a coupling to ensure stable power transmission. The outside of the lead screw 26 is connected to the inner wall of the threaded block 23 by threads. One end of the lead screw 26 is rotatably connected to the support block 27 by a bearing. The lower end of the support block 27 is fixedly connected to the top plate 2 by welding or bolt connection.

[0033] The switching mechanism includes an annular mounting block 3. The upper end of the annular mounting block 3 is fixedly connected to the lower end of the fixed bracket 24 by welding or bolt connection. The inner wall of the annular mounting block 3 is rotatably connected to the drive rod 31 through bearings, so that the drive rod 31 can rotate flexibly within the annular mounting block 3.

[0034] The upper end of the drive rod 31 is fixedly sleeved with a worm gear 32 by means of key connection or tight fit, and the lower end of the drive rod 31 extends to the bottom of the annular mounting block 3 and is fixedly connected with a cross mounting plate 33 by means of welding or bolt connection.

[0035] The upper end of the cross mounting plate 33 is fixedly mounted with a second servo motor 34 arranged in a ring array by bolts. The output shaft of the second servo motor 34 is fixedly connected to the drill rod 35 by a coupling. One end of the drill rod 35 passes through and extends to the bottom of the cross mounting plate 33.

[0036] The lower end of the annular mounting block 3 is provided with an annular groove 36. The inner wall of the annular groove 36 is connected to the arc-shaped sliders 37 arranged in an annular array by a sliding fit. The lower end of the arc-shaped sliders 37 is fixedly connected to the upper end of the cross mounting plate 33 by welding or bolt connection.

[0037] The upper end of the annular mounting block 3 is fixedly mounted with a third servo motor 38 by bolts. The output shaft of the third servo motor 38 is fixedly connected to the worm 39 by a coupling. The outer surface of the worm 39 is connected to the tooth surface of the worm wheel 32 by meshing.

[0038] The working process of this utility model:

[0039] Step 1: Fix the hardware parts on the processing table 1, start the servo electric cylinder 21, adjust the height of the top plate 2 according to the thickness of the hardware parts, so that the switching mechanism and drill rod 35 are at a suitable height position, then start the first servo motor 25, whose output shaft drives the lead screw 26 to rotate through the coupling, the threaded block 23 moves along the lead screw 26 and slides in the stroke groove 22, driving the fixed bracket 24 and the switching mechanism to move laterally, so that the drill rod 35 is aligned with the drilling position of the part;

[0040] Step two: When different diameter drill rods 35 are needed, the third servo motor 38 is started. Its output shaft drives the worm gear 39 to rotate via a coupling. The worm gear 39 meshes with the worm wheel 32, driving the drive rod 31 to rotate, which in turn drives the cross mounting plate 33 and the drill rod 35 to rotate. By controlling the rotation angle of the third servo motor 38, the required drill rod 35 is rotated to the working position. During this process, the annular slide groove 36 and the arc-shaped slider 37 cooperate to ensure rotational stability. After the drill rod 35 is switched, the servo electric cylinder 21 is started to retract, driving the top plate 2 and the drill rod 35 below to descend. At the same time, the corresponding second servo motor 34 is started. Its output shaft drives the drill rod 35 to rotate at high speed via a coupling to drill holes in the hardware parts.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
