Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically a positioning device for a drilling machine. Background Technology

[0002] A drilling machine is a processing device that forms through holes or blind holes by applying a rotating cutting force to a workpiece. It is widely used for drilling workpieces such as metal, plastic, and wood.

[0003] When existing drilling machines drill holes in workpieces, the drilling positions need to be marked on the workpiece to be drilled. Then, the workpiece is placed on the support plate of the drilling machine and clamped and fixed by a fixture to prevent the workpiece from moving during the drilling process. Most of the support plates and clamping mechanisms of existing drilling machines are rigid integrated structures. When adjusting the drilling position of the workpiece, the support plate must move synchronously, which causes the material drop groove on the support plate to be misaligned with the drilling drill rod. After the drill rod descends and penetrates the workpiece, the drill tip collides with the support plate, causing the drill bit to chip and damage the support plate.

[0004] Therefore, there is an urgent need for a dynamic clamping and adjusting positioning device for punching machines to solve the above-mentioned technical problems. Utility Model Content

The two ends of the rotating rod 14 are respectively connected to two connecting rods 15 through rotating shafts, and the other ends of the two connecting rods 15 are respectively rotatably connected to the two clamping plates 13 through rotating shafts. The center of the bottom of the rotating rod 14 is connected to the fixture control assembly 2 for transmission.

[0036] A through hole is provided in the middle of the clamping plate 13, and the through hole fits with the support plate 11. The movement trajectory of the clamping plate 13 is restricted by the support plate 11.

[0037] The top front and rear sides of the transverse plate 3 are fixed with vertical plates 31, and the bottom front and rear sides of the support plate 11 are fixedly connected to the vertical plates 31 respectively. The transverse plate 3 is fixedly connected to the support plate 11 through the vertical plates 31, so that when the transverse plate 3 moves laterally, it drives the clamp assembly 1 and the clamp control assembly 2 to move laterally synchronously.

The top of the first transmission shaft 23 is connected to the middle of the rotating rod 14.

[0039] The drive shaft 23 and the worm gear 24 are fixedly connected. The worm gear 24 is locked and fixed to the drive shaft 23 by bolts to prevent the worm gear 24 from sliding vertically along the drive shaft 23. The drive shaft 27 and the worm 25 are slidably connected. A key strip is provided on the outside of the drive shaft 27. The inner wall of the worm 25 fits against the drive shaft 27 and the key strip, so that the worm 25 can slide along the drive shaft 27. The rotation of the drive shaft 27 drives the worm 25 to rotate synchronously. The movement of the support plate 21 drives the worm gear 24 and the worm 25 to move synchronously, ensuring the meshing effect of the worm gear 24 and the worm 25.

[0040] The second drive shaft 27, the second slide rail 210, and the second lead screw assembly 29 are arranged in parallel, so that when the lead screw 52 of the second lead screw assembly 29 rotates, it drives the movable block 51 to move longitudinally, that is, to move in the front and back direction. The movable block 51 drives the support plate 21 to move longitudinally along the second slide rail 210, and the support plate 21 drives the worm gear 25 to move longitudinally along the second drive shaft 27 through the second bearing seat 26.

[0042] Please see Figure 8 The lead screw assembly 5 and the lead screw assembly 29 have the same structure. The lead screw assembly 5 is arranged horizontally, and the lead screw assembly 29 is arranged vertically. The lead screw assembly 5 includes a movable block 51, a lead screw 52, ​​and a motor 2 53.

The movable block 51 of the lead screw assembly 29 is vertically fixed to the bottom center of the support plate 21, and the motor 2 53 of the lead screw assembly 29 is fixed to the transverse plate 3.

[0043] Please see Figure 9The drilling machine assembly 7 includes a column 71, a top plate 72, an electric push rod 73, a motor mounting bracket 74, a limit rod 75, a drill rod motor 76, a drilling drill rod 77, an indicator light 78, and an electric push rod 79. The top plate 72 is fixed to the top of the column 71. An electric push rod 73 is vertically fixed to the front side of the top of the top of the top plate 72. The bottom end of the movable rod of the electric push rod 73 is fixedly connected to the motor mounting bracket 74. Limit rods are fixed to the front and rear sides of the top of the motor mounting bracket 74. Positioning rod 75, limiting rod 75 is set vertically and the limiting rod 75 vertically penetrates the top plate 72, drill rod motor 76 is installed in motor fixing bracket 74, the output shaft at the bottom end of drill rod motor 76 is connected to the drilling rod 77, electric push rod 79 is fixed in the middle of the rear side of column 71, and indicator light 78 is installed at the front end of the movable rod of electric push rod 79. Indicator light 78 is used to indicate the drilling position of drilling rod 77, and column 71 is fixed to the rear top of the bottom plate 4;

[0044] When the electric push rod 79 extends, the indicator light 78 and the drilling rod 77 are arranged in the same vertical line. The indicator light 78 emits an indicator light to indicate the drilling position of the drilling rod 77.

[0045] When the electric push rod 73 controls the motor mounting bracket 74 and the drill rod motor 76 to move downward, the electric push rod 79 first drives the indicator light 78 to move backward to retract, so as to avoid the indicator light 78 affecting the downward movement of the motor mounting bracket 74 and the drill rod motor 76.

[0046] Indicator 78 uses a Class 2 red laser indicator with a wavelength of 650nm, which is low in cost and highly sensitive to the human eye, meeting the needs of conventional industrial scenarios and facilitating the indication of the drilling position of the drill rod 77.

[0047] The drilling rod 77 is vertically aligned with the transverse slot frame 12, so that when the drilling rod 77 drills a hole in the workpiece, the drilling rod 77 penetrates the workpiece and extends into the transverse slot frame 12, avoiding contact between the drilling rod 77 and the support plate 11, which would cause damage to the support plate 11 or the drilling rod 77. In addition, the transverse slot frame 12 can be disassembled, which is convenient for cleaning the debris inside the transverse slot frame 12.

[0048] In use, the workpiece to be drilled is first placed on the support plate 11. The motor 28 generates power to drive the transmission shaft 27 to rotate. The transmission shaft 27 drives the worm 25 to rotate synchronously. The worm 25 drives the worm wheel 24 to rotate. The worm wheel 24 drives the rotating rod 14 to rotate through the transmission shaft 23. The rotation of the rotating rod 14 drives the two clamping plates 13 to retract through the two connecting rods 15. The workpiece to be drilled is clamped and fixed by the two clamping plates 13.

[0049] At this time, electric push rod 1 73 is in the retracted state and electric push rod 2 79 is in the extended state, that is, the drilling rod 77 and the indicator light 78 are on the same vertical line. The indicator light 78 emits an indicator light to indicate the drilling position of the drilling rod 77.

[0050] Move the workpiece to the position where it needs to be drilled so that it corresponds to the position of the indicator light emitted by indicator light 78. Control the operation of motor 53 of lead screw assembly 1 5 to drive lead screw 52 to rotate. The rotation of lead screw 52 drives the movable block 51 and the transverse plate 3 to move laterally through the threaded engagement between lead screw 52 and movable block 51. The transverse plate 3 drives the clamp assembly 1, clamp control assembly 2, and the workpiece clamped and fixed on clamp assembly 1 to move laterally, thereby adjusting the drilling position of the workpiece laterally. Control lead screw assembly 29 to drive support plate 21 to move longitudinally. Support plate 21 drives shaft seat 1 22. Drive shaft 1 23, worm gear 24, worm 25 and bearing seat 2 26 move synchronously, and drive shaft 1 23 drives rotating rod 14 to move synchronously. When rotating rod 14 moves, it drives clamping plate 13 to move synchronously through connecting rod 15. Clamping plate 13 drives the workpiece to be clamped to move longitudinally, and adjusts the drilling position of the workpiece longitudinally. When the workpiece is adjusted longitudinally, support plate 11 does not move, so that drilling rod 77 is vertically aligned with transverse groove frame 12, and drilling rod 77, drilling position of workpiece and transverse groove frame 12 are set in the same vertical line.

[0051] After the workpiece is adjusted to the drilling position, when drilling, the electric push rod 79 is retracted to move the indicator light 78 backward, and the electric push rod 73 is extended to move the motor fixing frame 74, the drill rod motor 76 and the drilling drill rod 77 downward. At the same time, the drill rod motor 76 is controlled to drive the drilling drill rod 77 to rotate, and the drilling drill rod 77 is used to drill holes in the workpiece.

[0052] After the workpiece is drilled, the electric push rod 73 is retracted, and the motor 28 drives the transmission shaft 27 to rotate in the opposite direction. The worm gear 24, worm 25 and transmission shaft 23 rotate in the opposite direction. The transmission shaft 23 drives the rotating rod 14 to rotate in the opposite direction. The rotating rod 14 rotates in the opposite direction and pushes the two connecting rods 15 to expand the space between the two connecting rods 13, so that the drilled workpiece can be removed.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0054] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
