Description

Technical Field

[0001] This invention relates to the field of cremation urn storage rack processing, and more particularly to a cutting device for processing cremation urn storage racks. Background Technology

[0002] In the manufacturing of cremation urn storage racks, the cutting device is a key piece of equipment to ensure product precision and assembly quality. It uses a saw blade to precisely cut the components of the cremation urn storage rack, directly affecting the efficiency of subsequent welding and assembly processes and the stability of the finished product. Strict requirements are placed on the smoothness of the cut, processing accuracy, and operational efficiency.

[0003] Existing cutting devices have revealed significant drawbacks during long-term use: the saw blade is prone to wear during high-frequency cutting, requiring machine shutdown for replacement or re-grinding when the wear reaches a certain level. However, traditional replacement and re-grinding processes are cumbersome, requiring manual disassembly of the saw blade, adjustment of the re-grinding equipment position, and calibration of installation accuracy. This not only consumes a significant amount of production time but also makes the saw blade's cutting performance susceptible to operational errors. Frequent shutdowns lead to processing interruptions, drastically reducing overall production efficiency. Furthermore, increased manual intervention increases the risk of fluctuations in cut accuracy, making it difficult to meet the high standards of stability and consistency required for cremation urn storage rack processing.

[0004] Based on the above situation, there is an urgent need for a cutting device that can automatically switch saw blades and perform grinding, which is of great significance for solving the pain points of existing technologies and improving processing efficiency and quality. Summary of the Invention

[0005] In order to overcome the shortcomings of existing cutting devices, such as complicated replacement and grinding steps after saw blade wear, frequent machine stops, low processing efficiency, and easy to affect cutting accuracy due to operational errors, the technical problem of the present invention is to provide a cutting device for processing urn storage racks.

A guide rail is fixedly connected to the worktable and passes through the inside of the protective cover. A first slider is slidably connected to the guide rail. A connector is fixedly connected to the first slider. A symmetrical connecting shaft is rotatably connected to the connector, and both the upper and lower connecting shafts are engaged with the drive shaft.

[0009] Furthermore, each connecting shaft is equipped with a flat-tooth saw blade, and each connecting shaft has an arc-shaped slot on the side near the drive shaft. The corresponding side of the drive shaft is equipped with a matching arc-shaped protrusion, forming a clutch-type power docking structure.

[0010] Furthermore, a second one-way gear is fixedly connected to the connector on the side near the stepper motor, and a second rack is fixedly connected to the worktable, which is located on the trajectory line of the horizontal movement of the second one-way gear, and the second one-way gear and the second rack mesh with each other.

[0011] Furthermore, counterweights are fixed to each of the symmetrically distributed connecting shafts, with their centers of gravity offset from the axis of the connecting shaft, forming a gravitational torque.

[0012] Furthermore, a second electric push rod is installed on the top of the protective cover. The telescopic part of the second electric push rod is fixed to a grinding wheel bracket. A grinder is installed on the grinding wheel bracket. The initial position of the grinder is directly above the saw tooth trajectory of the worn flat tooth saw blade above, so that it can be accurately aligned with the saw teeth to be ground.

[0013] Furthermore, a fixed frame is fixedly connected to the grinding wheel bracket, and an insert block serving as a single-tooth locking actuator is slidably connected to the inner wall of the protective cover. The bottom of the insert block is provided with a guide slope that matches the tooth shape of the flat-tooth saw blade. A second slider is slidably connected inside the insert block, and a spring is connected between the second slider and the insert block. The spring is wound around the insert block. A rectangular slot is opened on the fixed frame, and the second slider is embedded in the rectangular slot.

[0014] Furthermore, the grinding wheel support is fixedly connected to a bracket on the side away from the fixed frame, and a first rack is fixedly connected to the bracket. A transmission rod is rotatably connected to the inner wall of the protective cover, and a paddle is fixedly connected to its end. A first one-way gear is fixedly connected to the transmission rod. The first one-way gear and the first rack mesh with each other to form a one-way transmission angle adjustment system.

[0015] Furthermore, each flat-tooth saw blade is fixed to the connecting shaft by bolts.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0027] Example 1: A cutting device for processing cremation urn storage racks, such as Figure 1 and Figure 2 As shown, the device includes a worktable 1 as the main support, a cutting drive assembly for precise cutting, and a clamping and positioning assembly for firmly holding the material. A support frame 11 is fixedly connected to the worktable 1, and a first electric push rod 12 is mounted on the support frame 11. A pressure block 13 is fixedly connected to the extension end of the push rod 12. The pressure block 13 slides vertically on the support frame 11 to rigidly fix the material to be cut by applying vertical pressure, preventing displacement during cutting. A lead screw 17 is rotatably connected to the worktable 1, and a servo motor 16 is mounted on the worktable 1. Its output shaft is connected to... A lead screw 17 is fixedly connected to provide precisely controllable rotational power. A guide frame 18 is fixedly connected to the worktable 1, which is arranged side by side with the lead screw 17 on the worktable 1. A protective cover 14 is threadedly connected to the lead screw 17, which has both protective and load-bearing functions. The protective cover 14 slides horizontally on the guide frame 18. A cutting assembly (including a drive motor and a high-speed rotating cutter) is provided on the protective cover 14. A chip removal groove is opened on the worktable 1. The cutter of the cutting assembly extends into the groove, which not only provides clearance for the cutting action, but also allows the cutting chips to be directly discharged through the groove.

[0028] When it is necessary to cut the profile of the urn storage rack, the operation process is as follows: Place the profile to be processed on the workbench 1 directly below the pressure block 13, and adjust the profile so that the preset cutting line is aligned with the central axis of the chip removal groove; start the first electric push rod 12 to drive the pressure block 13 to move vertically downward until the pressure block 13 is in close contact with the upper surface of the profile and a preset clamping force is applied to complete the rigid fixation of the profile; simultaneously start the cutting assembly and the servo motor 16, the cutter of the cutting assembly rotates at high speed, and the servo motor 16 drives the protective cover 14 to move horizontally along the guide frame 18 through the lead screw 17, driving the rotating cutter to cut the profile along the cutting line; after the cutting is completed, the cutting assembly stops working, the first electric push rod 12 drives the pressure block 13 to reset vertically upward and release the profile, and the servo motor 16 rotates in the opposite direction to make the protective cover 14 drive the cutting assembly back to the initial position, and the cut profile can be removed.

[0029] like Figures 3-5 As shown, the cutting assembly includes a power transmission unit, a saw blade drive unit, and a guide clutch structure:

[0030] The power transmission unit includes a drive shaft 117 and a rotating shaft 1151 rotatably connected to the protective cover 14. Both ends of the drive shaft 117 are fixedly connected to drive wheels 115. A belt 116 is wound around the two drive wheels 115 to form a belt 116 transmission mechanism to realize power transmission. A stepper motor 114 is installed on the protective cover 14. Its output shaft is fixedly connected to the rotating shaft 1151 through a coupling, serving as the power source for the rotation of the saw blade.

[0031] Guide clutch structure: A guide rail 112 is fixedly connected to the worktable 1, which passes through the protective cover 14 and is used to provide a guide reference for the movement of the saw blade; a first slider 113 is slidably connected to the guide rail 112, and a connector 19 is fixedly connected to the first slider 113 to realize the rigid connection between the saw blade and the guide structure.

[0032] Saw blade drive unit: Connector 19 is rotatably connected to symmetrical connecting shafts 118. Each connecting shaft 118 is fixed with a flat tooth saw blade 15 by bolts. The bolt connection facilitates saw blade replacement and angle adjustment. Each connecting shaft 118 has an arc-shaped bayonet on the side near the drive shaft 117. The corresponding side of the drive shaft 117 is provided with a matching arc-shaped protrusion, forming a clutch-type power docking structure. The power supply and disconnection between the drive shaft 117 and the connecting shaft 118 are realized by the engagement and disengagement of the arc-shaped protrusion and the arc-shaped bayonet.

[0033] When the saw blade needs to be driven, the stepper motor 114 outputs torque to the rotating shaft 1151 through the coupling, and then transmits the power to the drive shaft 117 through the belt 116 transmission mechanism composed of the drive wheel 115 and the belt 116 so that it rotates synchronously.

[0034] At this time, the arc-shaped protrusion of the drive shaft 117 engages with the arc-shaped bayonet of the lower connecting shaft 118, and the power drives the lower flat tooth saw blade 15 to rotate at high speed through the lower connecting shaft 118. The upper connecting shaft 118 remains stationary because it is not engaged, and the upper saw blade does not work.

[0035] During the cutting operation, the protective cover 14 moves horizontally along the guide frame 18, while the first slider 113 slides synchronously along the guide rail 112 to ensure that the rotating lower flat tooth saw blade 15 is fed smoothly along the preset cutting line to complete the profile cutting.

[0036] As described in the background section, the saw blades of existing cutting devices are prone to wear during high-frequency cutting. Manual replacement or grinding is cumbersome and time-consuming, and manual operation is prone to positioning errors, resulting in reduced production efficiency and insufficient stability of cut accuracy. This makes it difficult to meet the high requirements for cut flatness and dimensional accuracy in the processing of urn storage racks. Therefore, it is necessary to design an automatic blade changing switching component to achieve rapid switching between the upper and lower flat tooth saw blades 15, thereby reducing downtime, avoiding operational errors, and ensuring efficient cutting operations.

[0037] like Figure 3As shown, specifically, the connecting member 19 has a second one-way gear 110 fixedly connected to the side near the stepper motor 114. It has one-way transmission characteristics and is triggered to rotate only in a specific direction. A second rack 111 is fixedly connected to the worktable 1, which is located on the trajectory line of the horizontal movement of the second one-way gear 110. The second one-way gear 110 and the second rack 111 mesh with each other to form a one-way triggered tool change transmission system, which is used to drive the connecting member 19 to rotate 180° within a preset stroke.

[0038] When the lower flat tooth saw blade 15 needs to be replaced due to wear, the operation process is as follows: control the stepper motor 114 to stop outputting power, and the lower flat tooth saw blade 15 stops rotating; the servo motor 16 drives the lead screw 17 to rotate, which drives the protective cover 14, flat tooth saw blade 15, connector 19, second one-way gear 110, connecting shaft 118 and first slider 113 to move to the left in the horizontal direction, and the first slider 113 slides synchronously along the guide rail 112.

[0039] When the first slider 113 continues to move to the left until it is freed from the constraint of the guide rail 112, the second one-way gear 110 and the second rack 111 enter the meshing state. During the movement, the second one-way gear 110 drives the connecting piece 19 to rotate precisely 180°, thereby driving the two flat tooth saw blades 15, the connecting shaft 118 and the first slider 113 on it to rotate synchronously 180°.

[0040] After rotation, the original lower connecting shaft 118 disengages from the drive shaft 117, and the original upper connecting shaft 118 precisely engages with the arc-shaped protrusion of the drive shaft 117 through the arc-shaped bayonet, thus achieving the reversal of the saw blade position; the servo motor 16 drives the lead screw 17 in reverse, causing the protective cover 14 and other components to move to the right, the first slider 113 re-engages into the guide rail 112, the second one-way gear 110 disengages, and after the components are reset, the stepper motor 114 restarts, and the newly switched lower flat tooth saw blade 15 rotates, allowing for continued efficient cutting operations.

[0041] Because the stepper motor 114 has the characteristic of rotating in integer numbers, it can keep the arc-shaped protrusion of the drive shaft 117 stable and horizontal when it stops. However, during the 180° rotation of the connector 19, the connector shaft 118 may not rotate into position, causing the arc-shaped locking jaws to fail to precisely engage with the arc-shaped protrusion of the drive shaft 117, thus affecting the stability of power transmission and the rotation accuracy of the saw blade. Therefore, a counterweight component needs to be designed to ensure that the connector shaft 118 rotates into position through gravity compensation, achieving precise docking with the drive shaft 117.

[0042] like Figure 5 and Figure 6 As shown, specifically, each of the symmetrically distributed connecting shafts 118 is fixed with a counterweight 119, which serves as a gravity-compensating positioning component. Its center of gravity is offset from the axis of the connecting shaft 118, forming a gravitational torque.

[0043] When the connector 19 drives the connecting shaft 118 to rotate for saw blade swapping, if the connecting shaft 118 has not rotated completely to 180°, the counterweight 119 can use the torque generated by its own gravity to drive the connecting shaft 118 to continue rotating to the preset position, ensuring that the arc-shaped bayonet of the connecting shaft 118 is precisely aligned and engaged with the arc-shaped protrusion of the transmission shaft 117.

[0044] When the stepper motor 114 stops running, the arc-shaped protrusion of the drive shaft 117 remains horizontal. During the process of the connector 19 driving the connecting shaft 118 to rotate 180°, if the connecting shaft 118 is not fully in place due to inertia or error, the counterweight 119 on its shaft will generate a compensating rotational force through the gravitational torque, driving the connecting shaft 118 to rotate precisely to 180°. At this time, the arc-shaped bayonet of the connecting shaft 118 is precisely engaged with the horizontal arc-shaped protrusion of the drive shaft 117, ensuring that after the stepper motor 114 restarts, the power can be stably transmitted to the connecting shaft 118 through the drive shaft 117, driving the flat tooth saw blade 15 to rotate at high speed and stably, ensuring cutting accuracy and stability.

[0045] After the flat-tooth saw blades 15 are swapped, if the worn saw blade on top is not repaired in time, it will accumulate wear and reach the replacement threshold, requiring a shutdown to replace the saw blade, resulting in production interruption and reduced efficiency. Therefore, a grinding component needs to be designed to grind and repair the worn saw blade online when it is idle on top, in order to extend the service life of the saw blade, reduce the frequency of downtime for replacement, and ensure continuous production efficiency.

[0046] like Figure 7 and Figure 8 As shown, specifically, a second electric push rod 2 is installed on the top of the protective cover 14, which serves as a grinding feed drive to control the lifting stroke of the grinder 21. The telescopic part of the second electric push rod 2 is fixedly connected to a grinding wheel bracket 22, which serves as a bearing structure for the grinder 21 to ensure the positioning accuracy of the grinder 21. The grinder 21 is installed on the grinding wheel bracket 22, which serves as a saw tooth repair actuator and is equipped with a high-speed rotating grinding wheel. The initial position of the grinder 21 is directly above the saw tooth trajectory of the worn flat tooth saw blade 15, which can accurately align with the saw teeth to be ground.

[0047] When it is necessary to grind the worn flat tooth saw blade 15, the operation procedure is as follows: control the extension part of the second electric push rod 2 to extend downward, drive the grinding wheel bracket 22 to move the grinder 21 downward synchronously, until the grinding wheel of the grinder 21 makes precise contact with the saw teeth to be ground on the flat tooth saw blade 15.

[0048] When the grinder 21 is started, the high-speed rotating grinding wheel grinds and repairs the contacting saw teeth. After the single tooth grinding is completed, the extension part of the second electric push rod 2 retracts upward, driving the grinder 21 to move upward and disengage from the saw teeth. The upper flat tooth saw blade 15 rotates precisely under the drive mechanism, so that the next saw tooth to be ground rotates to directly below the grinder 21.

[0049] Repeat the above process of "feed contact - single tooth grinding - upward disengagement - tooth position switching" until all worn saw teeth on the saw blade have been ground and repaired. The grinder 21 then returns to its initial position, awaiting the next grinding command. This process can be performed simultaneously with the saw blade's normal cutting operation (or completed during the cutting gap), enabling online repair of worn saw blades, extending their service life, and reducing downtime for replacement.

[0050] When the grinder 21 grinds the flat tooth saw blade 15, the saw blade is prone to tooth displacement due to vibration, resulting in decreased grinding accuracy and skewed tooth shape, making it difficult to achieve precise repair of each tooth. Therefore, it is necessary to design a limiting component to fix the saw blade position through a single tooth locking mechanism, ensuring that the grinding trajectory of each saw tooth by the grinder 21 is precise and controllable, and avoiding deviation.

[0051] Specifically, a fixed frame 29 is fixedly connected to the grinding wheel bracket 22, which serves as a limiting linkage carrier and transmits the displacement signal of the grinding wheel bracket 22. A sliding insert 28, acting as a single-tooth locking actuator, is slidably connected to the inner wall of the protective cover 14. The insert 28 has a guide slope at its bottom that matches the tooth profile of the flat-tooth saw blade 15, guiding the insert 28 to precisely engage with the teeth. When the insert 28 moves downwards, it can engage with the teeth of the flat-tooth saw blade 15 through the gap between the teeth, achieving rigid positioning of the saw blade.

[0052] The second slider 210 is slidably connected inside the insert 28 and serves as an elastic buffer connector 19. A spring 211 is connected between the slider 210 and the insert 28 to provide elastic preload and compensate for vibration displacement. The spring 211 is wound around the insert 28. A rectangular slot is opened on the fixing frame 29. The rectangular slot serves as a displacement linkage trigger structure. The second slider 210 is embedded in the rectangular slot to realize the transmission connection between the fixing frame 29 and the insert 28.

[0053] When saw teeth need to be ground: the second electric push rod 2 drives the grinding wheel bracket 22 to move down, and the fixing bracket 29 moves down accordingly. Through the rectangular slot, the second slider 210 moves down synchronously, thereby pushing the insert block 28 to slide down along the inner wall of the protective cover 14. The guide slope at the bottom of the insert block 28 fits against the tooth surface of the flat tooth saw blade 15, guiding the insert block 28 to accurately engage between the adjacent teeth of the tooth to be ground, realizing single-tooth locking of the saw blade.

[0054] During the grinding process, the vibration of the saw blade causes the insert 28 to be subjected to a reverse force. At this time, the second slider 210 slides relative to the insert 28, and the spring 211 undergoes elastic deformation and generates a preload force to ensure that the insert 28 is always tightly fitted with the teeth and maintains the locked state.

[0055] With the rigid locking of the insert block 28, the position of the tooth to be ground is fixed, and the grinding wheel of the grinder 21 can precisely grind the saw tooth along a preset trajectory. After the grinding of a single tooth is completed, the second electric push rod 2 drives the grinding wheel bracket 22 to move upward, and the fixing bracket 29 pulls the second slider 210 upward through the rectangular slot. The insert block 28 then disengages from between the teeth, the spring 211 resets, and the saw blade unlocks, so as to switch to the next tooth to be ground.

[0056] When the grinder 21 grinds the flat-tooth saw blade 15, each tooth needs to be processed individually. After grinding each tooth, the saw blade needs to be rotated at a specific angle so that the next tooth to be ground is precisely positioned under the grinder 21. The current operation lacks an automatic rotation mechanism, and reliance on manual adjustment easily leads to positioning errors, affecting grinding efficiency and accuracy. Therefore, an automatic rotation mechanism linked to the grinding action needs to be designed to allow the saw blade to rotate step-by-step at fixed angles, cooperating with the grinder 21 to complete the grinding of all teeth.

[0057] Specifically, the grinding wheel support 22 has a bracket 23 fixedly connected to the side away from the fixed frame 29. A first rack 24 is fixedly connected to the bracket 23, which serves as a linear transmission component to transmit lifting and lowering displacement. A transmission rod 26 is rotatably connected to the inner wall of the protective cover 14, serving as a torque transmission shaft. A paddle 27 is fixedly connected to its end, serving as a saw blade actuating component, which contacts the saw teeth to achieve rotational drive. A first one-way gear 25 is fixedly connected to the transmission rod 26, which has one-way transmission characteristics and outputs power only when the rack moves upward. The first one-way gear 25 and the first rack 24 mesh with each other to form a one-way transmission angle adjustment system, which is used to convert the lifting and lowering motion of the grinding wheel support 22 into the intermittent rotational motion of the saw blade.

[0058] The linkage process between the automatic rotation mechanism of the saw blade and the grinding action is as follows: The second electric push rod 2 drives the grinding wheel bracket 22 to move down, and the bracket 23 drives the first rack 24 to move down synchronously. At this time, the first one-way gear 25 remains stationary due to its one-way transmission characteristics, the transmission rod 26 and the paddle 27 do not move, the saw blade maintains its current position, and ensures that the grinder 21 is accurately aligned with the grinding teeth.

[0059] After the grinding machine 21 completes the grinding of the current tooth, the second electric push rod 2 drives the grinding wheel bracket 22 to move upward and reset. When the grinding wheel bracket 22 moves upward, the bracket 23 drives the first rack 24 to move upward synchronously and mesh with the first one-way gear 25 for transmission.

[0060] At this time, the first one-way gear 25 drives the transmission rod 26 to rotate, causing the paddle 27 to rotate one revolution around the axis of the transmission rod 26. During the rotation of the paddle 27, it contacts the saw teeth of the flat-tooth saw blade 15, pushing the saw blade to rotate precisely by one tooth pitch angle, so that the next tooth to be ground moves directly below the grinder 21.

[0061] Each time the grinding wheel bracket 22 completes a "downward grinding - upward reset" action, the paddle 27 drives the saw blade to rotate one tooth pitch until all saw teeth are ground. This process avoids saw blade rotation during the grinding stage through a unidirectional transmission design, ensuring precise coordination between grinding and rotation actions, and achieving fully automated tooth-by-tooth grinding operation.

[0062] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
