Description

Technical Field

[0001] This utility model relates to the field of water drilling technology, specifically to a scratch-resistant material handling mechanism for the water drilling process. Background Technology

[0002] In the field of water drilling, the material handling mechanism during the drilling process is the core component for efficiently acquiring samples or workpieces. Its structure needs to be adapted to the dual requirements of cooling and slag removal and precise material handling in water drilling operations. Currently, a variety of well-known technical solutions have been developed in the industry. The water drilling material handling mechanism is usually integrated with the drilling mechanism. The core consists of a drill barrel, a drive assembly, and a material handling execution unit. In the early days, the material handling execution unit was mostly an integrated structure that relied on the friction between the inner wall of the drill bit and the core sample to carry it out. Later, a dedicated extraction mechanism was gradually developed.

[0003] In precision applications such as rhinestone processing in jewelry, mechanical clamping mechanisms often use hard alloy materials for actuators such as arc-shaped pressure plates and snap rings. The small contact area between these actuators and the core sample or rhinestone makes the clamping force concentrated in a localized area, resulting in indentations and scratches on the core sample surface. Furthermore, the positioning and guiding structure of the rhinestone relies on guide rods or positioning pins with clearance fits. Over long-term operation, increased wear leads to a decrease in coaxiality, causing material misalignment and frictional scratches. Utility Model Content

[0004] The purpose of this utility model is to provide a scratch-resistant material handling mechanism for the water drill drilling process, in order to solve the problems mentioned in the background art where the mechanical clamping material handling mechanism is mostly made of hard alloy material and has a small contact area with the core sample or water drill, which makes the clamping force easily concentrated in a local area, resulting in indentations and scratches on the core sample surface. In addition, the positioning and guiding structure of the water drill relies on guide rods or positioning columns with clearance fit. During long-term operation, due to increased wear, the coaxiality decreases, and the material handling deviation causes friction and scratches.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant material handling mechanism for the water drill's drilling process, including a support base, which is the basic support structure of the equipment. A processing turntable is installed on the upper end of the support base, and an auxiliary turntable is engaged and connected to one side of the support base. The auxiliary turntable is the platform for the water drill's drilling. A lifting column is fixedly installed on the top of the auxiliary turntable, and a horizontal moving slide is installed on the top of the lifting column. A moving arm is connected to the horizontal moving slide, and a steering plate is rotatably connected to one end of the moving arm. The connection between the steering plate and the moving arm is penetrated by the shaft of a servo motor. One end of the steering plate is engaged with a positioning frame, and a push link is embedded in the positioning frame. The push link is a two-section sliding rod structure, and the outer sleeve of the push link is sleeved and installed with the grab bucket connecting seat. The sliding rod of the push link passes through the grab bucket connecting seat and is connected to the link gripper. A flexible claw plate is installed at the claw tip of the link gripper, and the upper end of the flexible claw plate is connected to the negative pressure adsorption plate through a strip. The negative pressure adsorption plate is connected to the connecting air box through a pipe, and the connecting air box is connected to the vacuum pump through a pipe.

[0006] By adopting the above technical solution, the combination of flexible claw plate and negative pressure adsorption plate avoids scratches from hard contact, and the lifting column, horizontal moving slide and servo motor achieve multi-dimensional precise adjustment to prevent material picking deviation.

[0007] Preferably, the machining turntable is located directly below the connecting rod gripper and the grab bucket connecting seat, and the surface of the machining turntable is provided with a slot for positioning the water drill machining station.

[0008] By adopting the above technical solution, the slot positioning water drill of the machining turntable is positioned directly below to ensure that the grippers are aligned, avoiding friction and scratches caused by the water drill shifting during material handling, and improving the material handling alignment accuracy.

[0009] Preferably, the lifting column is an electric lifting platform, and the lifting stroke of the lifting column is controlled in a closed loop by a displacement sensor.

[0010] Using the above technical solution, the electric lifting column, combined with the closed-loop control of the displacement sensor, accurately adjusts the material picking height, preventing the gripper from colliding and scratching the water drill due to height deviation, and ensuring stable accuracy during long-term operation.

[0011] Preferably, the upper end of the steering plate is provided with a ring adapted to the servo motor, and a vacuum pump is installed on the upper end of the steering plate, with the pipe of the vacuum pump output end passing through the steering plate.

[0012] By adopting the above technical solution, the servo motor adapter ring of the steering plate ensures stable angle adjustment, the vacuum pump is installed nearby to reduce air path loss, improve the angle alignment accuracy and negative pressure adsorption stability, and prevent deviation and scratches.

[0013] Preferably, the connecting air box is installed at the bottom end of the connecting rod gripper platform, and a grab bucket connecting seat is sleeved on the upper layer of the connecting rod gripper, and the rotating rod on the side wall of the grab bucket connecting seat is rotatably connected to the claw rod of the connecting rod gripper.

[0014] By adopting the above technical solution, the air path is shortened by connecting the air box to the adsorption plate, and the gripper connecting seat rotates the lever to link the gripper, so as to realize the rapid transmission of negative pressure and the smooth opening and closing of the gripper, preventing adsorption delay and gripping impact scratches.

[0015] Preferably, the negative pressure adsorption plate has an annular adsorption groove on its adsorption surface, and the annular adsorption groove is connected to the connecting air box through an internal air passage.

[0016] By adopting the above technical solution, the annular adsorption groove of the negative pressure adsorption plate increases the adsorption area and disperses the adsorption force, avoiding single-point adsorption that could cause the water drill to shift or the surface to be damaged, thus improving the adsorption stability.

[0017] Preferably, the flexible claw plate is made of silicone material, and the clamping surface of the flexible claw plate is provided with anti-slip micro-protrusions.

[0018] Using the above technical solution, the silicone flexible claw plate prevents hard scratches, and the anti-slip micro-convex texture increases friction to prevent falling, directly solving the problem of scratches on existing cemented carbide actuators, while ensuring that the material is not dropped during picking.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the anti-scratch material handling mechanism during the water drill's drilling process: 1. This mechanism achieves scratch prevention through the synergistic structure of a flexible claw plate and a negative pressure adsorption plate. The flexible claw plate is made of silicone material with anti-slip micro-textures on the clamping surface. Compared with hard alloy material, it can avoid rigid collisions through its soft properties. At the same time, the micro-textures form multiple flexible contacts with the surface of the rhinestone, increasing the contact area. Combined with the annular adsorption grooves on the adsorption surface of the negative pressure adsorption plate, which are connected to the air box through internal air channels, a uniform negative pressure can be generated after the vacuum pump is started. The rhinestone is pre-adsorbed and positioned, so that the flexible claw plate can smoothly fit along the surface of the rhinestone during subsequent clamping, avoiding local clamping force overload. The risk of indentation and scratch is eliminated from both the contact material and the force method. 2. The lifting column of this mechanism adopts an electric lifting platform and realizes closed-loop control of the lifting stroke through displacement sensors. It can accurately adjust the vertical height of the material picking component, avoiding the height deviation of traditional clearance fits. The horizontal moving slide drives the moving arm to achieve precise horizontal displacement. In conjunction with the servo motor, it drives the steering plate to rotate. The servo motor shaft passes through the connection between the steering plate and the moving arm, and can adjust the angle and posture of the connecting rod jaw and the negative pressure adsorption plate in real time to ensure coaxiality with the water drill. The entire positioning structure does not rely on easily worn clearance fit guide rods. Through electric control and angle adaptation, it can still maintain positioning accuracy after long-term operation, effectively avoiding friction and scratches caused by material picking deviation. 3. Smooth clamping is achieved through the transmission structure of the push link and the grab bucket connecting seat. The push link is a two-section sliding rod structure. Through the progressive sliding of the sliding rod and the outer sleeve, the grab bucket connecting seat moves slowly. The rotating rod on the side wall of the grab bucket connecting seat is rotatably connected to the claw of the link clamp, which can convert the linear motion of the push link into the smooth opening and closing of the claw. At the same time, the air circuit of the connecting air box and the vacuum pump are coordinated. The vacuum pump output pipe passes through the slot of the steering plate and is positioned directly below the link clamp and the grab bucket connecting seat. This can help the water drill maintain the stability of the working position before picking up the material and avoid positional displacement during clamping. Attached Figure Description

The grab bucket connecting seat 12 is fitted onto the outer sleeve of the push link 10, and the slide bar of the push link 10 is then passed through the grab bucket connecting seat 12 and connected to the claw bar of the link gripper 11. The flexible claw plate 15 is attached and fixed at the claw tip of the link gripper 11, and the negative pressure adsorption plate 14 is connected to the upper end of the flexible claw plate 15 by a strip. The connecting air box 13 is installed at the bottom end of the platform of the link gripper 11, and the negative pressure adsorption plate 14 is connected to the connecting air box 13 through a pipe. The connecting air box 13 is then connected to the output end of the vacuum pump 16 on the steering plate 7 through a pipe to ensure that the air circuit is sealed and leak-free. Finally, a displacement sensor is installed on the lifting column 4 and electrically connected to the control module of the lifting column 4 to complete the closed-loop control debugging.

The rotating rod on the side wall of the grab bucket connecting seat 12 is rotatably connected to the claw rod of the connecting rod claw 11. The adsorption surface of the negative pressure adsorption plate 14 is provided with an annular adsorption groove, and the annular adsorption groove is connected to the connecting air box 13 through an internal air passage. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, when the equipment is started, the processing turntable 2 drives the water drill to be picked up to rotate. The water drill processing station is positioned by the slot on the turntable. The auxiliary turntable 3 operates synchronously and works with the processing turntable 2 to realize the station flow. The displacement sensor of the control lifting column 4 controls the stroke to drive the horizontal moving slide 5, the moving arm 6 and the picking component to adjust the height in the vertical direction. At the same time, the horizontal moving slide 5 drives the moving arm 6 to move horizontally, so that the connecting claw 11 and the negative pressure adsorption plate 14 are accurately aligned with the target water drill on the processing turntable 2. The servo motor 8 is started, and its shaft drives the steering plate 7 and the positioning frame 9, the pushing connecting rod 10, the grab bucket connecting seat 12 and the connecting claw 11 below to rotate, adjusting the posture of the flexible claw plate 15 and the negative pressure adsorption plate 14 so that they are completely in contact with the surface of the water drill and eliminating the risk of angle deviation. When the vacuum pump 16 is started, the airflow enters the connecting air box 13 through the pipe and is transmitted to the negative pressure adsorption plate 14. The negative pressure adsorption plate 14 generates negative pressure through the annular adsorption groove of the adsorption surface, initially flexibly adsorbing the surface of the water drill. At the same time, the sliding rod of the push link 10 slides forward, pushing the grab bucket connecting seat 12. The rotating rod on the side wall of the grab bucket connecting seat 12 drives the link gripper 11 to slowly close. The flexible claw plate 15 flexibly contacts the surface of the water drill, dispersing the clamping force and achieving scratch-free clamping. The lifting column 4 and the horizontal moving slide 5 are adjusted to change position. Combined with the angle fine adjustment of the servo motor 8, the water drill is transferred to the target work position. Then, the push link 10 moves in the opposite direction, which drives the link gripper 11 to open. At the same time, the vacuum pump 16 is turned off, and the negative pressure adsorption plate 14 releases the water drill, completing one anti-scratch material picking cycle.

[0024] Working principle: When using the anti-scratch material handling mechanism during the drilling process of this water drill, the processing turntable 2 carries the water drill to be picked up. The water drill processing station is positioned by the slot on the turntable. The auxiliary turntable 3 cooperates with the processing turntable 2 to form a multi-station flow base. The lifting column 4 drives the horizontal moving slide 5, the moving arm 6 and the subsequent material handling components to adjust the height in the vertical direction. The horizontal moving slide 5 drives the moving arm 6 to move horizontally, so that the connecting rod gripper 11 and the negative pressure adsorption plate 14 are accurately aligned with the target water drill on the processing turntable 2. When the servo motor 8 is running, its shaft passes through the connection between the steering plate 7 and the moving arm 6, driving the steering plate 7 and the positioning frame 9 below, the push link 10, the grab bucket connecting seat 12, and the link gripper 11 to rotate and adjust the angle, so that the posture of the flexible claw plate 15 and the negative pressure adsorption plate 14 is completely matched with the water drill. Vacuum pump 16 starts and supplies air to connecting air box 13 through pipeline. Negative pressure is transmitted to negative pressure adsorption plate 14, and negative pressure is generated in the annular adsorption groove of its adsorption surface, which initially flexibly adsorbs the surface of the water drill. At the same time, the two-stage sliding structure push linkage 10 moves to push grab bucket connecting seat 12. The rotating rod on the side wall of grab bucket connecting seat 12 is linked with the claw of linkage gripper 11, so that linkage gripper 11 slowly closes. The silicone flexible claw plate 15 at the claw tip flexibly contacts the water drill, dispersing the clamping force to avoid scratching. After material is picked up, the lifting column 4 and the horizontal moving slide 5 move, and the servo motor 8 adjusts the angle to transfer the water drill to the target station. The push link 10 moves in the opposite direction, the link gripper 11 opens, the vacuum pump 16 stops, and the negative pressure adsorption plate 14 releases the water drill, completing one anti-scratch material picking process and increasing the overall practicality.
