Description

Technical Field

[0001] This application relates to the technical field of grinding machine loading, and more specifically, to a positioning device for a fully automatic loading and unloading table and a fully automatic loading and unloading table. Background Technology

[0002] A grinding machine is a mechanical tool used in industrial production for the double-end surface machining of products such as hydraulic and pneumatic components, hydraulic motor parts, automotive steering pump parts, refrigeration compressor parts, oil pump and nozzle parts, engine parts, high-precision bearings, seals, piston rings, measuring tools, molds, instruments, carbide inserts, ceramic valve cores, and magnetic materials.

[0003] In related technical fields, grinding machines typically include an internal gear ring and an external gear ring. When machining a workpiece, the workpiece is usually placed in a toothed loading disc with a gear ring structure. The gear ring structure of the toothed loading disc can mesh with the internal and external gear rings of the grinding machine. The toothed loading disc is placed in the grinding machine, and by driving the internal gear ring of the double-end face grinding machine to rotate, the toothed loading disc can both rotate on its own axis and revolve around the internal gear ring within the grinding machine, thereby completing the grinding of the workpiece.

[0004] In related technologies, during the loading process of a grinding machine, the toothed loading disc is usually manually placed into the grinding machine by the operator. When placing it in, the operator also needs to adjust the angle and position of the toothed loading disc so that the toothed ring structure of the toothed loading disc can mesh with the inner and outer toothed rings in the double-end face plate. Therefore, there is a defect of low loading efficiency. Utility Model Content

[0005] The purpose of this application is to provide a positioning device and a fully automatic loading and unloading platform for a fully automatic loading and unloading platform, in order to solve the problem of low loading efficiency in related technologies.

[0006] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application.

[0007] According to a first aspect of this application, a positioning device for a fully automatic loading and unloading platform is provided, comprising:

[0008] Feeding channel;

[0009] The feeding mechanism is used to push the toothed loading disc along the feeding channel to the toothed ring of the grinding machine's loading station;

[0010] An angle adjuster is configured to act on the toothed loading disc as it moves along the feeding channel to adjust the angle rotation of the toothed loading disc;

[0011] A material pusher calibration component is installed on the feeding mechanism. The material pusher calibration component is movably positioned above the toothed edge of the toothed loading disk. The material pusher calibration component is configured such that when it moves downward and inserts into the toothed groove of the toothed edge of the toothed loading disk, the angular position calibration of the toothed loading disk is completed. The material pusher calibration component moves downward during the rotation angle adjustment of the toothed loading disk by the angle adjuster until the material pusher calibration component is inserted into the toothed groove of the toothed loading disk.

[0012] In one exemplary embodiment of this application, a lifting structure is also included, which applies a downward force to the pusher calibration component during the rotation of the toothed loading disc.

[0013] In one exemplary embodiment of this application, the angle adjuster includes a calibration structure and a biasing member. The calibration structure is movable to the outside of the feeding channel, and the biasing member is used to apply a biasing force to the calibration structure toward the inside of the feeding channel.

[0014] When the pusher calibration component is not aligned with the tooth groove, the calibration structure can rotate the toothed loading disk under the action of the bias force so that the tooth groove is aligned with the pusher calibration component.

[0015] After the pusher calibration component is inserted into the toothed groove, the toothed loading disk cannot rotate. The toothed loading disk applies a force to the calibration structure and overcomes the bias force provided by the biasing component, causing the calibration structure to move to the outside of the first loading and unloading channel.

[0016] In one exemplary embodiment of this application, a positioning plate and a baffle strip are further included. The baffle strip is fixedly disposed on one side of the feeding channel along the length direction of the feeding channel, and the positioning plate is fixedly disposed on the baffle strip. The positioning plate is provided with a positioning block on the side facing the feeding channel for restricting the calibration structure from moving inward into the feeding channel.

[0017] In one exemplary embodiment of this application, the calibration structure includes:

[0018] A base plate is mounted on the positioning plate, one end of the base plate is rotatably connected to the positioning plate, and the other end of the positioning plate abuts against the side of the positioning block opposite to the feeding channel.

[0019] A cam follower is installed on the side of the base plate facing the feeding channel and can mesh with the toothed groove on the toothed loading disc.

[0020] In one exemplary embodiment of this application, a connector is further included, which passes through the base plate along the rotation axis of the base plate and is connected and fixed to the positioning plate.

[0021] In one exemplary embodiment of this application, the pusher calibration component is configured as a pusher gear ring, the arc of which is the same as the arc of the gear ring of the grinding machine located at the loading station, and a plurality of positioning pins are evenly distributed in the pusher gear ring, the spacing of which is equal to ...

[0022] In one exemplary embodiment of this application, the feeding mechanism includes:

[0023] A feeding gripper is used to clamp the toothed loading disc after being inserted into the center hole of the toothed loading disc;

[0024] The feeding slide is used to control the lifting and lowering of the feeding gripper;

[0025] The mounting bracket is used to support the feeding slide and the lifting structure.

[0026] In one exemplary embodiment of this application, a guide pad is laid on the feeding channel, and the guide pad has a V-shaped groove along its own length to reduce the contact area with the toothed loading disc.

[0027] According to a second aspect of this application, a fully automatic loading and unloading platform is provided.

[0028] The positioning device for a fully automatic loading and unloading platform described in any one of the above descriptions is provided.

[0029] The exemplary embodiments of this application may have some or all of the following beneficial effects:

[0030] In the positioning device for a fully automatic loading and unloading table provided in the example embodiment of this application, the loading mechanism pushes the toothed loading disc along the loading channel from the loading station of the grinding machine into the toothed ring at the loading end, realizing the automatic loading process. During the movement of the toothed loading disc within the loading channel, the angle adjuster allows the toothed loading disc to rotate. When the toothed loading disc rotates until its tooth groove aligns with the pusher calibration piece, the pusher calibration piece descends and inserts into the tooth groove, thereby completing the calibration of the angle position of the toothed loading disc. At this point, the angle at which the loading mechanism pushes the toothed loading disc into the grinding machine is precisely engaged with the toothed ring of the grinding machine. Therefore, through the above structure, on the one hand, automatic loading of the toothed loading disc is achieved without manual handling; on the other hand, the angle of the toothed loading disc can be adjusted during the loading process without human intervention. This effectively improves the loading efficiency of the grinding machine.

[0031] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0042] This application discloses a positioning device for a fully automatic loading and unloading table. The grinding machine suitable for this tooling disc positioning device can be a grinding and polishing machine, a high-precision grinding machine, or a double-end face grinding machine, but is not limited to these. Such grinding machines typically have an internal gear ring and an external gear ring. When the tooling disc carries the workpiece during grinding, it needs to mesh with both the internal and external gear rings. The rotation of the internal gear ring not only allows the tooling disc to rotate on its own axis but also to revolve around the internal gear ring, ensuring uniform grinding of the workpiece surface. Therefore, during grinding, the tooling disc needs to be configured as a toothed tooling disc with a toothed ring structure on its circumferential sidewalls. The center of the toothed tooling disc also needs to have a central hole for clamping.

[0043] Reference Figure 1 As shown in the embodiments of this application, the positioning device for a fully automatic loading and unloading platform disclosed includes:

[0044] Feeding channel 1;

[0045] The feeding mechanism 2 is used to push the toothed loading disc along the feeding channel 1 to the toothed ring of the grinding machine's loading station;

[0046] Angle adjuster 3 is configured to act on the toothed loading disc as it moves along the feeding channel 1 to adjust the angle rotation of the toothed loading disc;

[0047] A pusher calibration component is installed on the feeding mechanism 2. The pusher calibration component is movably positioned above the toothed edge of the toothed loading disk. The pusher calibration component is configured such that when it moves downward and can insert into the toothed groove of the toothed edge of the toothed loading disk, the angular position calibration of the toothed loading disk is completed. The pusher calibration component moves downward during the rotation angle adjustment of the toothed loading disk by the angle adjuster 3 until the pusher calibration component is inserted into the toothed groove of the toothed loading disk.

[0048] The toothed loading disc moves along the loading channel 1 via the loading mechanism 2. This mechanism pushes the toothed loading disc from the loading station of the grinding machine into the toothed ring along the loading channel 1, automating the loading process and significantly improving production efficiency. During the movement of the toothed loading disc within the loading channel 1, the angle adjuster 3 controls its rotation. When the toothed loading disc rotates to the point where its tooth groove aligns with the pusher calibration piece, the pusher calibration piece immediately descends and precisely inserts into the tooth groove. This action completes the calibration of the toothed loading disc's angular position, ensuring that the toothed ring structure of the toothed loading disc achieves ideal meshing with the inner and outer toothed rings of the grinding machine when the loading mechanism 2 pushes the toothed loading disc into the grinding machine.

[0049] The above structure not only enables automated feeding of the toothed loading pallet, completely freeing up manpower and avoiding the tediousness of manual handling, but also avoids errors caused by human operation; at the same time, during the feeding process, the angle of the toothed loading pallet can be automatically adjusted without human intervention, further improving production efficiency and ensuring processing accuracy.

[0050] In this embodiment, the tooling pallet positioning device further includes a lifting structure 4, which is configured as a cylinder, though this is not a limitation. During the toothed tooling pallet position calibration process, the lifting structure 4 consistently provides a downward force to the material pushing calibration component. This force can be changed by adjusting the output pressure setting of the pressure valve to make the material pushing calibration component work more stably and reliably.

[0051] When the pusher calibration component is not aligned with the tooth groove, the lifting structure 4 presses the pusher calibration component onto the upper surface of the material. When the toothed loading disc passes the angle adjuster 3, the angle adjuster 3 causes the angle of the toothed loading disc to rotate. At the instant when the tooth groove of the toothed loading disc aligns with the pusher calibration component, the pusher calibration component moves downward and inserts into the tooth groove under the force provided by the lifting structure 4, preventing the toothed loading disc from continuing to rotate, thereby achieving the calibration of the angle of the toothed loading disc.

[0052] In this embodiment, the angle adjuster 3 includes a calibration structure 31 and a biasing member 32. The calibration structure 31 is movable to the outside of the feeding channel 1, either by rotating or sliding to the outside of the feeding channel 1. The biasing member 32 acts on the calibration structure 31 to apply a biasing force toward the inside of the feeding channel 1.

[0053] When the toothed loading pallet passes the calibration structure 31, if the pusher calibration piece is not inserted into the tooth groove, the toothed loading pallet is in a rotatable state. Under the biasing force provided by the biasing member 32, the calibration structure 31 can make the toothed loading pallet rotate. When the pusher calibration piece is inserted into the tooth groove, the toothed loading pallet cannot rotate. When the toothed loading pallet continues to move towards the grinding machine, it can apply a force to the calibration structure 31 and overcome the biasing force provided by the biasing member 32, so that the calibration structure 31 moves to the outside of the loading channel 1, thereby achieving the purpose of avoidance and allowing the toothed loading pallet to pass smoothly. After the toothed loading pallet passes, the calibration structure 31 returns to its original position under the biasing force provided by the biasing member 32.

[0054] Reference Figure 1 and Figure 2As shown in this embodiment, the tooling pallet positioning device further includes a positioning plate 5 and a side strip 6. The side strip 6 is fixedly disposed on one side of the feeding channel 1 along its length direction, serving to guide the movement of the toothed tooling pallet. Simultaneously, the positioning plate 5 is fixedly mounted on the side strip 6, so that the side strip 6 also serves as a support for the positioning plate 5. The positioning plate 5 has a positioning block 51 on its side facing the feeding channel 1 to restrict the movement of the calibration structure 31 into the feeding channel 1. In this application, the positioning block 51 and the positioning plate 5 are an integrated structure. In other embodiments, the positioning block 51 and the positioning plate 5 can be connected by fixed, detachable, rotatable, snap-fit, or plug-in methods. The positioning block 51 restricts the position of the calibration structure 31, ensuring accurate positioning and good stability during use.

[0055] Reference Figure 3 and Figure 4 As shown, the calibration structure 31 further includes:

[0056] The base plate 311 is installed on the positioning plate 5. One end of the base plate 311 is rotatably connected to the positioning plate 5, and the other end of the base plate 311 abuts against the side of the positioning block 51 away from the feeding channel 1.

[0057] The cam follower 312 is installed on the side of the base plate 311 facing the feeding channel 1 and can mesh with the toothed grooves on the circumferential side wall of the toothed loading disc.

[0058] When the toothed loading plate passes the cam follower 312, the cam follower 312 will cause the toothed loading plate to rotate. As the toothed loading plate rotates, the pusher calibration piece will align with the tooth groove of the toothed loading plate and be inserted into the tooth groove to complete the tooth angle positioning of the toothed loading plate.

[0059] In this embodiment, the tooling pallet positioning device further includes a connector 9, which passes through the base plate 311 along its rotation axis and is then connected and fixed to the positioning plate 5. In this embodiment, the connector 9 is configured as a stepped screw; however, this is not a limiting factor.

[0060] Furthermore, in this application, the biasing element 32 is configured as a torsion spring, which is sleeved on the connecting element 9, so that the base plate 311 applies pressure to the inside of the feed channel 1 under the action of the torsion spring and abuts against the positioning block 51. Of course, this is not a limitation.

[0061] In one exemplary embodiment of this application, the pusher calibration component is set as a pusher tooth ring 7. The arc of the pusher tooth ring 7 is the same as the arc of the toothed ring of the grinding machine located at the loading station. A plurality of positioning pins 71 are evenly distributed in the pusher tooth ring 7. The spacing between the plurality of positioning pins 71 is equal to the tooth pin spacing of the toothed ring of the grinding machine located at the loading station. Alternatively, the spacing between the plurality of positioning pins 71 can be an integer multiple of the tooth pin spacing.

[0062] Specifically, the number of positioning pins 71 can be equal to the number of toothed pins, or the number of positioning pins 71 can be less than the number of toothed pins. When the number of positioning pins 71 is less than the number of toothed pins, the spacing between the positioning pins 71 can be the same as the spacing between the toothed pins, or the spacing between the positioning pins 71 can be an integer multiple of the toothed pin spacing.

[0063] When the feeding mechanism 2 pushes the toothed loading plate to the feeding end of the grinding machine, in order for the toothed loading plate to enter the grinding machine smoothly, the toothed ring at the feeding station of the grinding machine needs to be lowered below the feeding station during feeding. At this time, when the pusher tooth ring 7 pushes the toothed loading plate to the feeding station, the positioning pin 71 can replace some or all of the toothed pins, so that the toothed loading plate can be smoothly guided into the interior of the grinding machine. When the positioning pin 71 only replaces some of the toothed pins, it is necessary to ensure that the toothed loading plate can rotate into the interior of the grinding machine by engaging with the positioning pin 71. In this application, it is preferable that the number of positioning pins 71 is equal to the number of toothed pins, and the spacing between several positioning pins 71 is the same as the spacing between several toothed pins. Therefore, during feeding, several positioning pins 71 can replace all the toothed pins, so that the toothed loading plate can move more smoothly and steadily.

[0064] In this embodiment of the application, the feeding structure includes:

[0065] The feeding gripper 21 is used to insert into the center hole of the toothed material carrier and clamp the material carrier. Specifically, the feeding gripper 21 is preferably a three-point gripper, with a hand gripper installed on each of the three telescopic sliders of the three-point gripper. After the hand gripper is inserted into the center hole of the workpiece carrier, it clamps the workpiece carrier and can be dragged horizontally to complete the feeding. The three-point gripper can provide good stability for the material when transporting it. However, the three-point gripper is only an illustrative example and is not restrictive.

[0066] The feeding slide 22 is used to control the lifting and lowering of the feeding gripper 21;

[0067] Mounting bracket 23 is used to support the loading slide 22 and the lifting structure 4;

[0068] The module (not shown in the figure) is used to drive the feeding gripper 21, the feeding slide 22 and the mounting frame 23 to move along the feeding channel 1.

[0069] The module can use cylinders, hydraulic cylinders, linear motors, etc., without special restrictions. The moving end of its module component should be connected and fixed to the mounting bracket 23.

[0070] The telescopic end of the module is fixedly connected to the mounting bracket 23, enabling the module to move the loading gripper 21 and the loading table together. When loading is required, firstly, the module moves the loading gripper 21 above the toothed loading plate, with the loading gripper 21 positioned directly above the toothed loading plate; then, the loading slide 22 moves the loading gripper 21 downward, inserting it into the center hole of the toothed loading plate; next, the loading gripper 21 moves its three grippers outward to clamp the toothed loading plate; then, the module extends its telescopic end, causing the loading gripper 21 and the toothed loading plate to move together toward the loading end of the grinding machine; finally, the loading gripper 21 retracts its three grippers, the loading slide 22 moves the loading gripper 21 upward, and the module then moves the loading gripper 21 and the loading table back to their original positions, completing the loading operation.

[0071] It is worth noting that when the loading gripper 21 clamps the toothed loading plate with its three grippers, the clamping force applied by the grippers to the toothed loading plate can be controlled by installing a pressure control valve on the air supply line. As a result, when the toothed loading plate rotates, the rotational force will be greater than the clamping force applied by the grippers to the loading plate.

[0072] Reference Figure 1 As shown in this embodiment, a guide plate 8 is laid on the upper surface of the feeding channel 1. The guide plate 8 has a V-shaped groove 81 along the length of the feeding channel 1. The V-shaped groove 81 reduces the contact area with the toothed loading disc, thereby reducing the friction between them and the disc, and lowering the movement resistance caused by the adhesion of the grinding fluid to the toothed loading disc. This improves the smoothness of the toothed loading disc's movement in the feeding channel 1.

[0073] In this application embodiment, a fully automatic loading and unloading platform is also disclosed, including the positioning device for the fully automatic loading and unloading platform described above.

[0074] Other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the embodiments thereof.
