Description

Technical Field

[0001] The utility model relates to a drilling positioning device for a drilling and tapping machining center, belonging to the technical field of drilling and tapping machining centers. Background Art

[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. It achieves the desired effect by drilling holes in precision parts. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most companies consider fully automatic drilling machines as their development direction.

[0003] Authorization announcement number (CN 220782904 U) discloses a drilling and tapping center for workpiece processing, including a workbench and two control cabinets fixedly connected to the top of the workbench, a mounting frame fixedly connected between the two control cabinets, a drilling mechanism extending to the bottom of the mounting frame is arranged inside the mounting frame, a clamping mechanism is arranged on the top of the workbench, and the drilling mechanism includes a servo motor fixedly connected to the inside of the control cabinet, and an adjustment screw extending to the inside of the mounting frame is fixedly connected to the output shaft of the servo motor. The drilling and tapping center for workpiece processing drives the adjustment screw to rotate by setting a servo motor, and then drives the first threaded sleeve and the telescopic cylinder to move by rotating the adjustment screw, so as to facilitate the displacement adjustment of the electric drill bit, so that it can drill holes in different positions of the workpiece, and then drives the electric drill bit to move by setting a telescopic cylinder, so as to facilitate drilling holes in the workpiece, thereby achieving the effect of drilling holes in the workpiece.

[0017] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0018] 1. The utility model sets a clamping mechanism. Through the output of the motor, the driving gear drives the gear ring to rotate. With the rotation of the gear ring, the driven gear rotates synchronously. At this time, the gear plate moves inward due to the rotation of the driven gear and the driving gear, and synchronously drives the connecting rod and the fixed plate to move inward. With the movement of the fixed plate, the fixed plate drives the clamping plate to move inward to complete the clamping of parts. Parts of different sizes can be clamped, which improves the use range of the clamp and avoids the deviation of parts due to contact with the drilling device during drilling. By setting a disassembly mechanism, when different types of clamps need to be replaced, the pull rod is pulled to move outward. With the movement of the pull rod, the slide plate drives the plug to move synchronously. The tool is then moved inwardly, at which time the plug is removed from the inner cavity of the socket, and the hard spring is deformed due to the force. The splint is then pulled inwardly, and a splint that matches the shape of the component is replaced. The replaced splint is then plugged into the inner cavity of the socket slot, and the pull rod is then released. Due to the disappearance of the force, the hard spring is deformed again, and its own tension pushes the slide plate to move inwardly, and the plug block moves inwardly with the slide plate synchronously, and is plugged into the inner cavity of the socket, completing the installation of the splint. By replacing the splint, it can be effectively avoided that when the shape of the splint does not match the shape of the component to be processed, the component will not fall off from the inner side of the splint when it contacts the drilling device, thereby improving the fixing effect of the component and facilitating use.

[0019] The invention can limit the movement of the clamping plate by providing a moving groove, so as to avoid the displacement of the clamping plate when the clamping plate moves, thereby affecting the clamping work of the parts; the displacement groove can be provided to limit the moving direction of the tooth plate, so as to avoid the tooth plate changing its direction position during the movement, thereby affecting the fixing work of the parts; the sliding groove can be provided to limit the moving direction of the gear ring, so as to effectively avoid the gear ring from shifting in direction when the movement is carried out, thereby improving the clamping work of the clamping plate on the parts; the limiting groove can be provided to limit the movement of the slide plate, so as to avoid the slide plate changing its direction when the slide plate moves, thereby affecting the installation or disassembly work of the clamping plate; the slot can be provided to limit the moving direction of the plug block, so as to effectively avoid the displacement of the plug block when the movement is carried out, thereby making it impossible to disassemble or install the clamping plate; the sliding groove can be provided to limit the pull rod, so as to avoid the displacement of the moving direction of the pull rod, thereby improving the stability of the pull rod when it moves; and the fixing bolt can be provided to disassemble the disassembly mechanism as a whole, so as to facilitate the repair or replacement of the parts in the disassembly mechanism.

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0033] The top of the support frame 1 is provided with a clamping mechanism 2, which includes a clamping box 201, which is fixedly installed on the top of the support frame 1, and a motor 202 is fixedly installed on the bottom of the support frame 1. The output end of the motor 202 is fixedly connected to a driving gear 203, and a gear ring 204 is provided on the inner side of the clamping box 201. The driving gear 203 is meshed with the right side of the inner side of the gear ring 204, and the left side of the bottom of the inner cavity of the clamping box 201 is movably connected to a driven gear 205. , the left side of the driven gear 205 is meshed with the left side of the inner side of the gear ring 204, a sliding rod 206 is fixedly installed at the middle end of the bottom of the inner cavity of the clamping box 201, and tooth plates 207 are slidably connected to the left and right sides of the surface of the sliding rod 206, and the outer side of the tooth plate 207 is meshed with the inner side of the driving gear 203 and the driven gear 205, and connecting rods 208 are fixedly installed on the outer sides of the two tooth plates 207, and fixed plates 209 are fixedly installed on the inner sides of the two connecting rods 208;

[0034] A disassembly mechanism 3 is provided on both the front and rear sides of the inner side of the fixed plate 209, and the disassembly mechanism 3 includes a disassembly box 301, which is provided on the front and rear sides of the inner side of the fixed plate 209, and the upper and lower sides of the inner cavity of the four disassembly boxes 301 are fixedly installed with sliding bars 302, and the surfaces of the eight sliding bars 302 are slidably connected with slide plates 303, and hard springs 304 are fixedly installed on the outer sides of the four slide plates 303 and located on the outer sides of the slide bars 302, and plug blocks 305 are fixedly installed on the inner sides of the four slide plates 303, and pull rods 306 are fixedly installed on the inner sides of the four slide plates 303, and plug-in grooves 310 are opened on the inner sides of the two fixed plates 209, and the outer sides of the two splints 4 are clamped in the inner cavities of the two plug-in grooves 310.

[0035] By setting the clamping mechanism 2, through the output of the motor 202, the driving gear 203 drives the gear ring 204 to rotate, and with the rotation of the gear ring 204, the driven gear 205 rotates synchronously. At this time, the toothed plate 207 moves inward due to the rotation of the driven gear 205 and the driving gear 203, and synchronously drives the connecting rod 208 and the fixed plate 209 to move inward. With the movement of the fixed plate 209, the fixed plate 209 drives the clamping plate 4 to move inward to complete the clamping of the parts. The parts of different sizes can be clamped, which increases the use range of the clamp and avoids the deviation of the parts due to contact with the drilling device during drilling.

At this time, due to the disappearance of the force, the hard spring 304 is deformed again, and its own tension pushes the slide plate 303 to move inward, and the plug block 305 moves inward synchronously with the slide plate 303 and is plugged into the inner cavity of the socket 5 to complete the installation of the splint 4. By replacing the splint 4, it can be effectively avoided that when the shape of the splint 4 does not match the shape of the component to be processed, the component will not fall off from the inner side of the splint 4 when it contacts with the drilling device, thereby improving the fixing effect of the component and facilitating use.

Limiting grooves 307 are provided on the upper and lower sides of the inner cavity of the four disassembly boxes 301, and the upper and lower sides of the four slides 303 are slidably connected.

[0038] By setting the moving groove 210, the movement of the clamping plate 4 can be limited to avoid the clamping plate 4 from being offset when moving, thereby affecting the clamping work of the parts. By setting the displacement groove 211, the moving direction of the tooth plate 207 can be limited to avoid the tooth plate 207 from changing its direction during the movement, thereby affecting the fixing work of the parts. By setting the sliding groove 212, the moving direction of the gear ring 204 can be limited to effectively avoid the gear ring 204 from being offset when moving, thereby improving the clamping work of the clamping plate 4 on the parts. By setting the limiting groove 307, the sliding plate 303 can be The movement is limited to prevent the direction of the slide plate 303 from changing when it moves, thereby affecting the installation or disassembly of the splint 4. By setting the slot 308, the moving direction of the plug block 305 can be limited, effectively preventing the plug block 305 from offset when it moves, thereby making it impossible to disassemble or install the splint 4.

At this time, due to the disappearance of the force, the hard spring 304 is deformed again and pushes the slide plate 303 through its own tension. Move inward, the plug block 305 moves inward synchronously with the slide plate 303, and is inserted into the inner cavity of the socket 5 to complete the installation of the splint 4, and then through the output of the motor 202, the driving gear 203 drives the gear ring 204 to rotate, and as the gear ring 204 rotates, the driven gear 205 rotates synchronously.
