Description

Technical Field

[0001] The present invention relates to the technical field of wood furniture processing, and particularly relates to a tenon grinding device. Background Art

[0002] The grinding process of wood furniture is a crucial link in the furniture production process, which directly affects the painting quality and overall aesthetics of the furniture. Grinding can remove impurities such as burrs, floating rust, oil stains, and dust on the substrate, laying a foundation for the subsequent painting work. At the same time, through grinding, the roughness of the painted surface of the workpiece can be reduced, the surface with putty can be made smooth, and the mechanical adhesion of the coating can be improved. Among the grinding processing methods, there are dry grinding, wet grinding, mechanical grinding, and polishing. Among them, dry grinding is suitable for the grinding of hard and brittle paint types, but a large amount of dust will be generated during operation, affecting environmental hygiene. Wet grinding can reduce grinding marks, improve the smoothness of the coating, and save sandpaper and labor. However, it should be noted that after wet grinding, the paint layer should be applied only after the grinding powder layer is completely dry, otherwise the paint layer is likely to turn white. Substrates with strong water absorption are not suitable for wet grinding. Mechanical grinding is suitable for large-area or large-scale construction objects and can improve work efficiency.

[0003] In mechanical grinding, there are grinding tools for grinding various woods. Commonly used ones include fixed grinding machine tables and hand-held grinders. It can be understood that for the fixed grinding machine table, the operator holds the wood to be ground and contacts the grinding part of the machine table to perform grinding at specific positions, such as fine parts like the edge of a wooden strip or the edge of a tenon. For the hand-held grinder, it is used for larger-sized boards or wooden strips. The operator holds the grinder and goes to the place where the wood needs to be ground to perform targeted grinding operations.

[0004] The current tenon grinding device includes the above-mentioned fixed grinding machine table. During the operation, the operator holds the tenon to the grinding device to perform edge grinding. The grinding efficiency is low and the labor cost is high. To improve the grinding efficiency, a pipeline-type grinding method has also emerged. The operator arranges the tenons in sequence on the transmission line, and the transmission line transports the tenons to the grinding place for grinding. However, this method is only limited to grinding the cutting part on one side of the tenon. During operation, the production line needs to be stopped, the tenon needs to be adjusted to the other side, and then the production line is restarted for grinding, resulting in poor continuity of tenon grinding. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a tenon grinding device to fundamentally solve the problems of low grinding efficiency and poor grinding continuity of the current tenon grinding device.

[0010] Further, the feeding mechanism further includes a transmission frame arranged on the side of the sliding frame away from the clamping plate, and rubber plates embedded in the opposite direction of the clamping plates. The side of the transmission frame away from the clamping plate abuts against the displacement seat, and the abutting side is designed in an inclined manner, so that the displacement seat drives the sliding frame and drives the clamping plates to move in the opposite direction to clamp the workpiece between the two clamping plates.

[0011] Further, the clamping mechanism includes threaded rods movably arranged on both sides of the displacement seat, a first gear arranged on the side of the threaded rod away from the displacement seat, a clamping plate arranged on the side of the threaded rod away from the first gear, and at least two guide rods arranged on the clamping plate and close to the threaded rod side.

The side of the transmission frame 64 away from the clamping plate 63 abuts against the displacement seat 52, and the abutting side is designed in an inclined manner, so that the sliding frame 61 is driven by the displacement seat 52 and drives the two clamping plates 63 to move in the opposite direction, so as to clamp the workpiece 56 between the two clamping plates 63.

Among them, during the vertical sliding process of the displacement seat 52, the first gear 74 will be driven to mesh with the first rack 75, and the threaded rod 73 will be driven to move toward or away from the workpiece 56 based on the displacement seat 52 to realize the clamping of the workpiece 56. The alignment mechanism 8 includes a fixed frame 81 fixedly connected to the displacement seat 52, a rotating frame 82 movably arranged on the side of the fixed frame 81 away from the displacement seat 52, a second gear 84 and an overrunning clutch 83 arranged in sequence on one side of the rotating frame 82, a reset member arranged on the side of the rotating frame 82 away from the overrunning clutch 83, an inclined plane frame 811 arranged in the arc-shaped groove at the front end of the displacement seat 52, and a second rack 85 arranged on both sides in the frame 1 and meshing with the second gear 84. Among them, the second gear 84 is fixedly connected to the rotating frame 82 and the reset member.

[0024] In specific implementation, first, the operator can stack the workpieces 56 to be polished on the feeding component 5 in sequence with the tenons facing the polishing component side, and support them through the supporting plate 53. During this process, the two clamping plates 63 on the feeding mechanism 6 can also be used to initially position the workpieces 56 to initially ensure the stability of the workpieces 56 and prevent misalignment at the stacking position of the subsequent workpieces 56 from affecting subsequent blanking. Then, after the operator stacks the workpieces 56, the overall tenon polishing device can be driven through the controller. In some alternative embodiments, the controller can be set at any position convenient for the operator to operate on the tenon polishing device, and the controller can be an MCU (Microcontroller Unit;A microcontroller unit (MCU) chip is used to control the tenon grinding device through the MCU chip. Among them, the tenon grinding device is electrically connected to the controller, and the electrical connection includes wired connection and wireless connection. The wireless connection methods include, but are not limited to, Bluetooth connection, WiFi, IF radio frequency, and zigbee. The wired connection methods include, but are not limited to, the USB line connecting the tenon grinding device and the controller. The tenon grinding device performs the grinding operation on the workpiece 56. Specifically, the operator can wake up the hydraulic push rod 51 through the controller. In some alternative embodiments, the hydraulic push rod 51 can also be an electric telescopic rod, so that the displacement seat 52 at the output end of the hydraulic push rod 51 drives vertically downward. During the process, the material support plate 53 for carrying the workpiece 56 will move with the displacement seat 52. And during the process, the contact shaft 54 on the side of the material support plate 53 away from the workpiece 56 will move along the track of the groove frame 55 to ensure the perpendicularity and stability during the downward drive of the displacement seat 52. In addition, in some alternative embodiments, the connection between the contact shaft 54 and the material support plate 53 can also be detachable. The operator can select to install material support plates 53 with different widths on the contact shaft 54 according to the width of the subsequent workpiece 56 to increase the distance between the two opposite material support plates 53, so as to adapt to workpieces 56 with different widths. Correspondingly, the connection between the two servo motors 3 and the mounting frame 2 can also be a sliding connection, which can be adaptively adjusted according to the grinding width corresponding to the tenon on the workpiece 56. Immediately afterwards, during the lowering process of the displacement seat 52, the feeding mechanism 6 is driven to partially clamp the stacked workpieces 56 in the middle. It should be noted that when the displacement seat 52 is at the top of the machine frame 1, both sides of the top of the displacement seat 52 are in contact with the two transmission frames 64. In this state, the clamping plates 63 are in a relatively unfolded state and do not contact the workpiece 56. And during the lowering process of the displacement seat 52, it will slowly disengage from the contact with the transmission frame 64. And during the process, the sliding frame 61 and the clamping plates 63 will be driven by the elastic force of the first return spring 62 to close and clamp towards the middle workpiece 56. At the same time, because the displacement seat 52 has a certain lowering stroke during the lowering process, and the clamping plates 63 do not contact the workpiece 56 during this stroke, one workpiece 56 in contact with the displacement seat 52 follows the displacement seat 52 to lower, while the remaining workpieces 56 are uniformly clamped by the clamping plates 63 and wait for the subsequent recovery and loading of the displacement seat 52. In addition, to avoid the situation that the workpiece 56 is knocked and damaged during the clamping process by the clamping plates 63, a rubber plate 9 can be provided on the side of the clamping plates 63 close to the workpiece 56. While improving the protection of the workpiece 56, the characteristics of the rubber itself can also increase the friction at the contact part with the workpiece 56 to a certain extent, thereby improving the stability of the workpiece 56 during the clamping process.;

[0025] Further, after the feeding mechanism 6 drives the rear displacement seat 52 to still maintain the lowering operation, the alignment mechanism 8 can also be driven to perform orthotropic adjustment on the position of the workpiece 56 during the process. Specifically, the second gear 84 will engage and drive with the second rack 85 when the displacement seat 52 is initially lowered, so that the second gear 84 drives the rotating frame 82 and the reset member to rotate towards the grinding end of the workpiece 56. During the process, the pushing wheel 89 on the reset member pushes the workpiece 56 towards the direction of being inserted into the displacement seat 52. It should be noted that since the two sides of the feeding mechanism 6 are restricted to initially ensure the accuracy of the workpiece 56 on the X-axis, and then the reset member is used to adjust the accuracy of the workpiece 56 on the Y-axis. After the position adjustment of the workpiece 56 is completed, under the continuous drive between the second gear 84 and the second rack 85, the hexagonal bolt 87 on the side close to the pushing wheel 89 flips towards the inclined surface frame 811 and abuts against it. During the abutting process, the hexagonal bolt 87 is pressed and drives the second reset spring 88 in the protective sleeve 86 to retract. During this process, the pushing wheel 89 disengages from the contact with the workpiece 56, and the rotating frame 82 rotates along the track of the inclined surface frame 811 until it stops after returning to the initial state.

[0026] Furthermore, after the displacement seat 52 still maintains the lowering operation, and the feeding mechanism 6 and the alignment mechanism 8 are driven in sequence, the clamping mechanism 7 can be driven to clamp a workpiece 56 that follows the lowering of the displacement seat 52 to prevent misalignment during the subsequent grinding of the workpiece 56. Specifically, during the lowering process of the displacement seat 52, the first gears 74 movably arranged on both sides thereof will enter the driving stroke of the first racks 75 arranged on both sides inside the machine frame 1, and the first gears 74 will preferentially engage and contact with the uppermost first rack 75. During the engagement process, the first gears 74 will rotate axially along the vertical track of the first racks 75, and the first gears 74 will drive the threaded rod 73 in its axial direction to perform threaded transmission with the displacement seat 52, and then the threaded rod 73 will push the clamping plate 72 on the side away from the first gear 74 to move towards the side close to the workpiece 56 to achieve the clamping operation of the workpiece 56. It should be noted that the threaded rod 73 and the clamping plate 72 are movably connected.

[0027] Finally, the displacement seat 52 drives the aligned and clamped workpiece 56 down to the grinding roller 4, and drives the grinding roller 4 to grind both sides of the tenon part of the workpiece 56 by driving the servo motor 3. During the process, the displacement seat 52 continuously maintains the lowered state, and after the workpiece 56 passes between the two grinding rollers 4, the first gear 74 enters the meshing area of the bottom rack 75 and meshes for transmission. It should be noted that the bottom rack 75 and the top rack 75 are arranged oppositely and the rack transmission trajectories are arranged in the reverse direction, so that the driving first gear 74 rotates reversely and controls the clamping plate 72 to move away from the workpiece 56, and releases the clamping of the workpiece 56 and exports the workpiece 56 to the bottom of the frame 1. After that, the hydraulic push rod 51 drives the displacement seat 52 to lift and return to the initial state. In addition, it should be noted that during the lifting process of the displacement seat 52, the second gear 84 and the first gear 74 will successively contact the second rack 85 and the first rack 75. During this process, since the alignment mechanism 8 has returned to the initial state, the overrunning clutch 83 provided on the second gear 84 can be used to limit the rotation operation of the second gear 84, so that the alignment mechanism 8 always maintains the initial state. At the same time, the first gear 74 will cause the clamping plate 72 to expand through reverse drive, so as to vacate the middle position for accommodating other workpieces 56. At the same time, when the displacement seat 52 is lifted, the transmission frame 64 can also be driven, and through the inclined design at the bottom of the transmission frame 64, the lifting driving force can be applied along its inclined direction during the lifting process, so that the transmission frame 64 drives the sliding frame 61 and the clamping plate 63 to move horizontally, and applies pressure to the first return spring 62, and finally causes the two opposite clamping plates 63 to expand, and the workpiece 56 located between the two clamping plates 63 falls off the clamping restriction and drops onto the material supporting plate 53 between the displacement seats 52, completing the secondary lowering of the workpiece 56, and continuously performing the above operations until the two clamping plates 63 have successively completed the grinding operation.

[0028] In summary, for the tenon grinding device in the above embodiments of the present invention, the feeding assembly 5 drives the workpiece 56 to move closer to or away from the grinding assembly, and during the process, the feeding assembly 5 successively drives the feeding mechanism 6 linked to it to lower a single workpiece 56, and at the same time drives the alignment mechanism 8 to flip towards the workpiece 56 to achieve the correct positioning of the workpiece 56. After the correct positioning of the workpiece 56, the clamping mechanism 7 linked to it is driven to clamp the single-lowered workpiece 56, ensuring the accurate position and continuity of the lowering process of the workpiece 56, and enabling the workpiece 56 to finally pass through the grinding assembly, and at the same time completing the grinding operations on both sides of the tenon of the workpiece 56, greatly improving the grinding efficiency and solving the problems of low grinding efficiency and poor grinding continuity of the current tenon grinding devices.
