Description

Technical Field

[0001] The invention relates to the technical field of guide post grinding, in particular to a guide post grinding device for precision mould processing. Background Art

[0002] Guide pins are used in combination with components in precision molds to ensure that the mold moves with precise positioning and are guiding elements for the mold stroke. The surface of the guide pins needs to be ground during the processing. Precision molds play a key role in intelligent manufacturing equipment. If the guide pins in the precision molds have the following problems, they cannot be used effectively.

[0003] In the prior art, a grinding device is used to grind the surface of the guide post during guide post processing. Grinding the surface of the guide post mainly has the functions of improving surface quality, ensuring matching accuracy, improving wear resistance, improving corrosion resistance and eliminating stress. Usually, a fixed fixture is used in conjunction with a movable grinder to grind the surface of the guide post. The most common type of guide post is a step type. When a fixture is used to fix the step type guide post, the fixture contacts the step of the guide post. There is a cavity between the cylindrical surface of the guide post and the fixture. This may cause the guide post to deviate toward the cavity due to the presence of the guide post step when the fixture clamps the guide post, causing the guide post to tilt slightly, thereby affecting the grinding effect on the guide post surface. In addition, the contact surface between the guide post and the mold is single. After manually manipulating the mold to move horizontally, only the cylindrical surface of the guide post can be ground. After grinding, the guide post needs to be loosened from the fixture and rotated to grind the cylindrical surface of the guide post that has not yet been ground. This is time-consuming and labor-intensive, and is not conducive to the efficiency of guide post grinding.

[0016] As described above, the characteristics and advantages of the guide post grinding device for precision mold processing in the present invention are: By setting the slots and the clamping jaws, the staff rotates the adjustment seat so that when the sliding seat approaches the guide column, the protrusion of the clamping jaw close to the chuck first contacts the step of the guide column. After the sliding seat moves further, the clamping jaw rotates under the action of the guide column step, so that the protrusion of the clamping jaw away from the chuck contact the cylindrical surface of the guide column. Under the action of the four clamping jaws contacting the steps and column of the guide column at the same time, the guide column is clamped, and the steps and column of the guide column are positioned at the same time, which effectively avoids the situation where the guide column is clamped to the steps of the guide column and causes the guide column to deviate from the fixture cavity, and also achieves the effect of auxiliary positioning, which helps to improve the grinding accuracy. Through the arrangement of the driving gear and the belt pulley 1, the output shaft of the motor 1 synchronously drives the ratchet wheel to rotate, the driving gear drives the reciprocating screw to rotate through the driven gear, the moving seat reciprocates under the reciprocating thread of the reciprocating screw and the limiting action of the slide bar, the belt pulley 1 drives the chuck to rotate through the belt and the belt pulley 2, and then drives the guide column to rotate, and when moving, the motor 2 drives the grinding wheel at the bottom end of the grinding wheel shaft to rotate through the driving bevel gear 2 and the driven bevel gear 2 for grinding, when the grinding wheel reciprocates, the guide column rotates by itself and cooperates with the reciprocating grinding wheel to thoroughly grind the cylindrical outer surface of the guide column, and there is no need to manually adjust the guide column, which is easy to use; By setting the docking groove and the docking block, when the grinding of the cylindrical outer surface of the guide column is completed, the motor drives the active gear to rotate, so that the active gear drives the driven gear to rotate, and the ratchet plate does not rotate at the same time. When the driven gear rotates, it drives the reciprocating screw rod to rotate, so that the moving seat moves to the end face of the guide column away from the chuck under the limit of the reciprocating thread of the reciprocating screw rod and the sliding rod. Then, the cylinder starts to withdraw the driven gear from the active gear through the ring sheet. Under the action of the chuck driven by the motor to rotate continuously, the grinding wheel with constant height cooperates with the rotating guide column to realize the outermost ring grinding on the end face of the guide column. After the grinding wheel at the bottom of the grinding wheel shaft moves to the center of the circle aligned with the end face of the guide column, the entire end face of the guide column can be ground, and there is no need to set grinding wheels in different directions. The movable end of the electric telescopic rod 2 continues to extend so that the slide table sends the guide column into the chuck through the rotating shaft and the mechanical claw. After the chuck clamps the guide column, the movable end of the electric telescopic rod 2 is retracted, so that the slide table is reset and the connecting rod and the slider are reset, so that the connecting rod drives the rotating shaft to rotate ninety degrees, and drives the mechanical claw to return to a vertical downward state. Then the electric turntable is started to rotate the guide column to be processed to the bottom of the mechanical claw. After the guide column in the chuck is processed, the electric telescopic rod 2 cooperates with the mechanical claw to send the guide column to be processed into the chuck again, so as to achieve the effect of automatic continuous processing.

[0022] Further, such as Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, an automatic loading assembly is arranged on the top of the base 2, and the automatic loading assembly includes a fixed plate 601 fixedly installed on the top of the base 2, a slide rail 602 is fixedly connected inside the fixed plate 601, a slide table 603 is slidably connected to the slide rail 602, a rotating shaft 604 is rotatably connected inside the slide table 603, a slide groove 605 is provided on the fixed plate 601, a connecting rod 606 is fixedly connected to one end of the rotating shaft 604 close to the fixed plate 601, a slider 607 is fixedly connected to one end of the connecting rod 606 away from the rotating shaft 604, and the slider 607 is away from the connecting rod 606. One end is slidably connected in the slide groove 605, an electric telescopic rod 608 is fixedly installed on the side of the top of the base 2 away from the fixed frame 402, the movable end of the electric telescopic rod 608 passes through the fixed plate 601 and is fixedly connected to the slide 603, an electric turntable 609 is fixedly installed on the top of the bottom plate 1, a grabbing groove 610 is opened on the base 2, a mechanical claw 611 is fixedly installed on the side of the rotating shaft 604 away from the connecting rod 606, the slide groove 605 is L-shaped, and a placement groove is set on the top of the electric turntable 609, and the mechanical claw 611 is aligned with the placement groove when it is vertically downward.

[0023] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows: The initial state is: The active bevel gear 309 does not rotate, the sliding seat 303 is located on the side of the sliding stroke away from the center of the chuck 302, the motor 403 is not powered on, the movable seat 408 is located at one end of the reciprocating screw 406 and the sliding rod 407 close to the fixed frame 402, the ratchet in the ratchet plate 410 contacts the protrusion of the ratchet wheel 409 under the action of the torsion spring, the movable end of the electric telescopic rod 502 is extended, the motor 504 is not powered on, the movable end of the electric telescopic rod 608 is retracted, the slide 603 is located on the side of the slide rail 602 close to the electric telescopic rod 608, the connecting rod 606 is in a vertical upward state, the slider 607 is located at the top of the slide groove 605, and the mechanical claw 611 is in a vertical downward state.

[0024] The working status is: Feeding guide pin: When the controller controls the electric turntable 609 to rotate so that any guide column to be processed is located directly under the mechanical claw 611, the mechanical claw 611 starts to grab the guide column to be processed, and then the electric telescopic rod 608 starts to extend the telescopic end, pushing the slide 603 to slide on the surface of the slide rail 602, so that it slides to the side away from the electric telescopic rod 608. When the slide 603 slides, it pulls the connecting rod 606 and the slider 607, so that the connecting rod 606 is pulled by the slide 603, and the slider 607 is limited by the slide groove 605 to make the rotating shaft 604 rotate, so that This drives the mechanical claw 611 to rotate in the direction away from the electric telescopic rod 608 until the slide 603 continues to slide through the connecting rod 606 to bring the slider 607 into the horizontal section of the slide groove 605. At this time, the rotating shaft 604 rotates ninety degrees with the cooperation of the slide groove 605, the connecting rod 606 and the slider 607, so that the guide column grasped by the mechanical claw 611 is directed toward the center of the chuck 302. Then, the movable end of the electric telescopic rod 608 continues to extend, so that the slide 603 sends the guide column into the chuck 302 through the rotating shaft 604 and the mechanical claw 611.

[0025] Clamping guide pin: After the mechanical claw 611 sends the guide post into the chuck 302 and the step of the guide post is aligned with the slot 304, the mechanical claw 611 releases the limit through the controller. At this time, the staff uses a tool to rotate the adjustment seat 310 that is equidistantly annular on the chuck 302, so that the adjustment seat 310 drives the active bevel gear 1 309 to rotate, thereby driving the driven bevel gear 1 308 to rotate under the meshing action, thereby driving the threaded disk 306 to rotate, and then through the cooperation of the threaded disk 306 and the threaded seat 307, the four sliding seats 303 are driven to slide synchronously toward the center of the chuck 302, and the clamping claw 305 at the bottom of the slot 304 is close to the guide post, and the clamping claw 305 is close to The protrusion on one side of the chuck 302 will first contact the step of the guide column, and when the sliding seat 303 moves further, the side of the jaw 305 that contacts the step of the guide column is pushed by the step of the guide column and rotates, so that the jaw 305 rotates away from the protrusion on one side of the chuck 302 to contact the guide column body, thereby both ends of the jaw 305 are clamped and contacted on the outer surface of the guide column, and then the four jaws 305 are in contact with the steps and the column body of the guide column at the same time to achieve the clamping effect on the guide column, and at the same time position the steps and the column body of the guide column, effectively avoiding the situation where the guide column is clamped to the step of the guide column and causing the guide column to be deflected, and achieving the effect of auxiliary positioning.

[0026] Grinding guide posts: When the guide post is fixed in the chuck 302, the movable end of the electric telescopic rod 1 502 is retracted, so that the lifting seat 503 drives the grinding wheel shaft 501 to slide downward until the grinding wheel at the bottom of the grinding wheel shaft 501 contacts the grinding surface of the guide post. Then, the motor 1 403 and the motor 2 504 are started synchronously. When the motor 1 403 is started, the driving gear 404 is driven to Figure 7 In the middle state, the motor 403 rotates counterclockwise, so that the output shaft of the motor 403 synchronously drives the ratchet 409 to rotate, and drives the ratchet plate 410 to rotate through the ratchet pawl. At this time, the driving gear 404 drives the sleeve rod 413 to rotate through the driven gear 405, and the sleeve rod 413 drives the reciprocating screw rod 406 to rotate through the limited position cooperation of the docking groove 415 and the docking block 416. The moving seat 408 reciprocates under the limited position action of the reciprocating thread of the reciprocating screw rod 406 and the sliding rod 407, and the ratchet plate 410 drives The pulley 1 411 rotates synchronously, and the pulley 1 411 drives the chuck 302 to rotate through the belt and the pulley 2 412, and then drives the guide column to rotate. When moving, the motor 2 504 drives the grinding wheel at the bottom end of the grinding wheel shaft 501 to rotate for grinding through the active bevel gear 2 505 and the driven bevel gear 2 506. When the grinding wheel reciprocates, the guide column rotates by itself and cooperates with the reciprocating grinding wheel to thoroughly grind the cylindrical outer surface of the guide column. There is no need to manually adjust the guide column, which is easy to use.

[0027] Grinding end face: When the cylindrical outer surface of the guide post is ground, the motor 403 drives the driving gear 404 to Figure 7In the middle state, the driving gear 404 rotates counterclockwise, so that the driving gear 404 drives the driven gear 405 to rotate, while the ratchet plate 410 does not rotate. When the driven gear 405 rotates, the sleeve rod 413 rotates, and the sleeve rod 413 drives the reciprocating screw rod 406 to rotate through the limited position cooperation of the docking groove 415 and the docking block 416, so that the moving seat 408 moves to the end face of the guide column away from the chuck 302 side under the limited position of the reciprocating thread of the reciprocating screw rod 406 and the sliding rod 407. At this time, the cylinder 417 is started, and its movable end pushes the ring plate 414 moves in the direction away from the reciprocating screw rod 406, so that the ring piece 414 pushes the sleeve rod 413 and the driven gear 405 to move in the direction away from the reciprocating screw rod 406, so that the driven gear 405 is no longer meshed with the driving gear 404. At this time, when the motor 1 403 is started and rotated, it cannot drive the reciprocating screw rod 406 to rotate, so that the moving seat 408 fixes the grinding wheel shaft 501 in a position in contact with the end face of the guide column, and then the motor 1 403 is started, and the motor 1 403 drives the driving gear 404 to Figure 7 In the middle state, it rotates counterclockwise, thereby driving the chuck 302 to rotate through the ratchet 410, the pulley 1 411, the belt and the pulley 2 412, and then driving the guide column to rotate. At this time, the motor 2 504 drives the grinding wheel shaft 501 to rotate through the active bevel gear 2 505 and the driven bevel gear 2 506. At this time, the grinding wheel first contacts the outermost side of the guide column end surface and is fixed when the electric telescopic rod 1 502 is not extended. Therefore, under the action of the motor 1 403 driving the chuck 302 to rotate continuously, the height of the grinding wheel and the rotating guide column are kept constant. The outermost ring is ground on the end face of the guide column, and then the movable axis of the electric telescopic rod 502 shrinks a distance equal to the thickness of the grinding wheel, so that the lifting seat 503 drives the grinding wheel shaft 501 to descend, so that the grinding wheel is closer to the center of the end face of the guide column, and then the end face is ground again with the cooperation of the grinding wheel at a fixed height and the rotation of the guide column. This process is repeated until the grinding wheel at the bottom of the grinding wheel shaft 501 moves to align with the center of the end face of the guide column, and then the entire end face of the guide column can be ground without setting grinding wheels in different directions.

[0028] Adjust grinding intensity: When grinding the cylindrical surface of the guide column, the lifting seat 503 is driven down by the electric telescopic rod 502 and then the grinding wheel shaft 501 is driven down. The distance between the grinding wheel at the bottom end of the grinding wheel shaft 501 and the guide column can be adjusted, thereby adjusting the pressure of the grinding wheel on the cylindrical surface of the guide column, and then changing the intensity of grinding the cylindrical surface of the guide column, so that the grinding intensity can be adjusted accordingly according to the roughness of the cylindrical surface of the guide column.

[0029] Continuous grinding: When a guide post is located in the chuck 302 for grinding, the movable end of the electric telescopic rod 608 is retracted, so that the slide 603 is reset while driving the connecting rod 606 and the slider 607 to reset. During this process, the slider 607 at the top of the connecting rod 606 slides into the vertical end of the slide groove 605, so that the connecting rod 606 drives the rotating shaft 604 to rotate ninety degrees, thereby returning from a horizontal state to a vertical state. When rotating ninety degrees, it drives the mechanical claw 611 to return to a vertical downward state. Then the controller controls the electric turntable 609 to start, and rotates the guide post to be processed to just below the mechanical claw 611. After the guide post in the chuck 302 is processed, the electric telescopic rod 608 cooperates with the mechanical claw 611 to send the guide post to be processed into the chuck 302 again, so as to achieve the effect of automatic continuous processing.
