Description

Technical Field

[0001] This utility model belongs to the technical field of deburring devices, specifically relating to a deburring device for the production of wear-resistant sheets. Background Technology

[0002] Wear-resistant plates are die-cast parts made of wear-resistant metal and are typically installed at the joints of cylindrical parts to prevent surface wear. Because burrs are generated on the outer surface of wear-resistant plates after processing, and the more burrs there are, the lower the quality, deburring is necessary after die-casting.

[0003] In related technology (Chinese utility model patent with announcement number CN208680510U), a deburring device with waste chip collection function for the production of wear-resistant sheets is disclosed. The device includes a shell, a hydraulic cylinder is provided on the top outer wall of the shell, and a first through hole is provided on the top outer wall of the shell. The piston rod of the hydraulic cylinder is inserted into the inner wall of the first through hole. A lifting shell is provided on the bottom outer wall of the hydraulic cylinder, and a second through hole is provided on the top outer wall of the lifting shell. A water spray plate is provided on the bottom outer wall of the lifting shell, and a water spraying through hole is provided on the bottom outer wall of the water spray plate. A deburring brush is provided on the bottom outer wall of the shell. A water tank is provided on the bottom inner wall of the shell, and a return water hole is provided on the top outer wall of the water tank. A water pump is provided on the top outer wall of the water tank, and a water pump inlet is provided with a water suction pipe, which is inserted into the water outlet of the water tank. By setting an internal expansion chuck and a deburring brush, the wear-resistant sheet is clamped onto the internal expansion chuck. The motor drives the chuck to rotate, which in turn drives the wear-resistant sheet to rotate. The deburring brush removes the burrs on the surface of the wear-resistant sheet, eliminating the need for manual removal with a trimming knife, saving manpower and improving work efficiency.

[0004] In the aforementioned existing processing methods, when using internal support positioning to deburr and grind the circumference of the wear-resistant sheet's sidewalls, the circular end faces on both sides of the wear-resistant sheet are perpendicular to the axis of the deburring brush, preventing the brush from effectively processing the end faces. However, the burrs on the wear-resistant sheet are mainly concentrated on the circular end faces, making the existing equipment ineffective at deburring the entire wear-resistant sheet and failing to meet the requirements for efficient surface treatment. Utility Model Content

[0005] To address the problem that existing equipment cannot effectively deburr the circular end faces of wear-resistant sheets, resulting in poor overall deburring performance and failing to meet the demand for efficient deburring of wear-resistant sheet surfaces, this invention provides a deburring device for wear-resistant sheet production. This device facilitates a one-time concentrated grinding process on the circular end faces where burrs are concentrated, requiring only supplementary processing of the sidewall circumference afterward. Since the surface area of ​​the sidewall circumference of the wear-resistant sheet is significantly smaller than that of the circular end face, this process's priority treatment of the end face greatly improves deburring efficiency, meeting the industrial production requirements for efficient deburring of wear-resistant sheet surfaces. The specific technical solution is as follows:

[0006] A deburring device for producing wear-resistant sheets, used for deburring wear-resistant sheets, includes: a frame, a turntable, a support column, a first cylinder, a drive seat, a first fixed seat, a connecting arm, a first U-shaped seat, a rotating shaft, and a positioning arm. The turntable is rotatably disposed in the middle of the frame; the support column is vertically and fixedly installed in the middle of the upper surface of the turntable; the first cylinder is installed on the upper surface of the turntable; the drive seat is slidably sleeved on the support column, and the drive seat is truncated cone-shaped with a narrower top and wider bottom, and the output end of the first cylinder is fixedly connected to the lower surface of the drive seat; the first fixed seat is fixedly installed on the support column; multiple connecting arms are provided, and the multiple connecting arms are equidistant from each other along the circumference and fixedly installed on the side wall of the first fixed seat; the first U-shaped seat is fixedly installed at the end of the connecting arm opposite to the first fixed seat; the rotating shaft is rotatably connected inside the first U-shaped seat; the positioning arm is fixedly installed on the rotating shaft, and the inwardly rotating positioning arm positions the side wall of the wear-resistant sheet.

[0007] In the above technical solution, a positioning block is installed on the top side wall of the positioning arm, and the positioning block is an elastic body with its own elasticity.

[0008] In the above technical solution, the positioning arm is driven by a linkage component, which includes: a second fixed seat, a mounting plate, a movable arm, a second U-shaped seat, a slide groove, a spring, and a drive pin. The second fixed seat is fixedly installed on the support column and is located below the first fixed seat. Multiple mounting plates are provided, and these plates are equidistantly arranged below the second fixed seat. The movable arm slides through the side wall of the mounting plate and slides in contact with the side wall of the drive seat. The second U-shaped seat is fixedly installed on the end of the movable arm facing away from the drive seat. The slide groove is vertically formed on the side wall of the second U-shaped seat. The spring is sleeved on the movable arm, and both ends of the spring are fixedly connected to the mounting plate and the second U-shaped seat, respectively. The drive pin is slidably embedded in the inner cavity of the slide groove and is rotatably connected to the free end of the bottom of the positioning arm.

[0009] In the above technical solution, the connecting arm and the moving arm are arranged vertically parallel to each other.

[0010] In the above technical solution, the outer wall of the end of the moving arm near the drive seat has an arc-shaped structure.

[0011] In the above technical solution, a support plate is fixedly installed at the top of the support column, and the center of the support plate is coaxial with the center of the support column, and the wear-resistant sheet is placed on the support plate.

[0012] In the above technical solution, the height of the top of the positioning arm is lower than the height of the upper surface of the wear-resistant sheet.

[0013] In the above technical solution, the turntable rotates circumferentially through a drive assembly, which includes a through hole, a motor frame, and a drive motor. The through hole extends from top to bottom through the middle of the platform. The motor frame is fixedly installed at the bottom of the platform. The drive motor is installed inside the motor frame, and the output end of the drive motor is fixedly connected to the middle of the bottom of the turntable.

[0014] The above technical solution also includes a grinding assembly, which includes a bracket, a second cylinder, and a grinding plate. The bracket is fixedly installed on the rear side wall of the platform; the second cylinder is installed on the top of the bracket; and the grinding plate is installed at the bottom output end of the second cylinder.

[0015] In the above technical solution, the length of the grinding plate is greater than the radius of the wear-resistant sheet.

[0016] The deburring device for producing wear-resistant sheets according to this utility model has the following advantages compared with the prior art:

[0017] I. To address the problem that existing equipment cannot effectively deburr the circular end face of wear-resistant sheets, resulting in poor overall deburring effect and difficulty in meeting the demand for efficient deburring of wear-resistant sheet surfaces, this utility model adopts multiple sets of positioning arms to evenly position the side wall of the wear-resistant sheet circumferentially, exposing the circular end face of the wear-resistant sheet to the grinding station. This facilitates one-time concentrated grinding of the circular end face where burrs are concentrated, and subsequent processing only requires supplementary processing of the side wall circumference. Since the circumferential surface area of ​​the wear-resistant sheet side wall is significantly smaller than that of the circular end face, this process of prioritizing the end face can greatly improve deburring efficiency and meet the industrial production needs of efficient deburring of wear-resistant sheet surfaces.

[0018] II. This utility model achieves synchronous rotation and engagement of multiple positioning arms with the side wall of the wear-resistant sheet through the coordinated action of components such as the drive seat, moving arm, and drive pin, thus forming circumferential positioning of the wear-resistant sheet. This method does not require individual driving of each positioning unit, has high synchronization, and ensures that the wear-resistant sheet is accurately centered on the support tray, thereby ensuring its positional accuracy relative to the grinding station of the grinding plate, and providing a reliable reference positioning for subsequent deburring processing.

[0019] Third, in this utility model, when the drive seat moves upward, it drives multiple sets of positioning arms to rotate inward synchronously and engage with the side wall of the wear-resistant plate to complete the positioning. When the drive seat moves downward, the positioning arms rotate in the opposite direction to disengage from the positioning by means of the elastic force of each spring. That is, this utility model can realize the positioning adjustment of the wear-resistant plate by multiple sets of positioning arms through the lifting and lowering movement of the drive seat. The switching of the positioning state can be realized by the linear movement of a single component. There is no need for a complex multi-drive system, which reduces the manufacturing cost and maintenance difficulty of the equipment and makes it more practical.

[0020] IV. This utility model achieves efficient deburring by driving the positioned wear-resistant plate to rotate, which, in conjunction with the stationary deburring mode of the grinding plate, generates relative friction between the rotating wear-resistant plate and the stationary grinding plate. Compared with the traditional grinding plate rotation grinding method, this solution, through the relative motion design of the fixed grinding part and the rotating workpiece, can more accurately control the friction path and force uniformity, avoid centrifugal force loss and vibration error caused by the high-speed rotation of the grinding part, thereby improving deburring efficiency and surface processing quality.

[0021] V. By setting the length of the grinding plate to be greater than the radius of the wear-resistant sheet, this utility model ensures that the grinding range of the grinding plate can completely cover the circumferential end face of the wear-resistant sheet during the rotation of the wear-resistant sheet. This size setting avoids the problem of incomplete coverage of the grinding area due to insufficient length of the grinding plate, eliminates the risk of burr residue that may exist in traditional processes, and thus ensures the comprehensiveness and thoroughness of deburring.

[0022] In summary, this invention achieves balanced circumferential positioning of the wear-resistant sheet's sidewalls using multiple positioning arms, prioritizing concentrated grinding of the circular end faces where burrs are concentrated, significantly improving deburring efficiency. Synchronous positioning of multiple positioning arms through component collaboration ensures accurate centering, providing a reliable benchmark for subsequent processing. Positioning adjustment is achieved solely through the lifting of the drive seat, simplifying the structure and reducing costs and maintenance difficulty. The deburring mode, which drives the wear-resistant sheet to rotate while the grinding plate remains stationary, precisely controls the friction path and force, improving efficiency and quality. Setting the grinding plate length to be greater than the radius of the wear-resistant sheet ensures comprehensive grinding coverage, eliminating the risk of burr residue. Attached Figure Description

Detailed Implementation

[0030] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] A deburring device for producing wear-resistant sheets, used for deburring wear-resistant sheets 23, includes: a frame 1, a turntable 5, a support column 6, a first cylinder 7, a drive seat 8, a first fixed seat 9, a connecting arm 10, a first U-shaped seat 11, a rotating shaft 12, and a positioning arm 13. The turntable 5 is rotatably disposed in the middle of the frame 1; the support column 6 is vertically and fixedly installed in the middle of the upper surface of the turntable 5; the first cylinder 7 is installed on the upper surface of the turntable 5; the drive seat 8 is slidably sleeved on the support column 6, and the drive seat 8 is a frustum shape that is narrower at the top and wider at the bottom. The output end of the first cylinder 7 is fixedly connected to the lower surface of the drive seat 8, that is, the first cylinder 7 can cause the drive seat 8 to move vertically along the support column 6; the first fixed seat 9 is fixedly installed on the support column 6; multiple connecting arms 10 are provided, and the multiple connecting arms 10 are equidistant from each other along the circumference and fixedly installed on the side wall of the first fixed seat 9. Specifically, the connecting arms 10 are provided with... Four connecting arms 10 are provided, with adjacent pairs of connecting arms 10 spaced 90 degrees apart. A first U-shaped seat 11 is fixedly installed on the end of the connecting arm 10 away from the first fixed seat 9. A rotating shaft 12 is rotatably connected to the first U-shaped seat 11 via a bearing. A positioning arm 13 is fixedly installed on the rotating shaft 12. The positioning arm 13, which rotates inward and engages with the side wall of the wear-resistant sheet 23, positions the side wall of the wear-resistant sheet 23. Specifically, the connecting arms 10 and the first U-shaped seat 11 provide support for the rotation of the rotating shaft 12 and the positioning arm 13. That is, when the positioning arm 13 rotates synchronously under the action of external force and engages with the side wall of the wear-resistant sheet 23, it forms a circumferential positioning of the wear-resistant sheet 23. Conversely, it disengages the wear-resistant sheet 23 from the positioning arm 13. The height of the top of the positioning arm 13 is lower than the height of the upper surface of the wear-resistant sheet 23 to ensure that after the side wall of the wear-resistant sheet 23 is clamped and positioned by the positioning arm 13, the positioning arm 13 will not affect the grinding work of the upper surface of the wear-resistant sheet 23.

[0032] This invention uses multiple sets of positioning arms 13 to achieve circumferentially balanced positioning of the sidewall of the wear-resistant sheet 23, ensuring that the circular end face of the wear-resistant sheet 23 is fully exposed to the grinding station. This facilitates concentrated grinding of the circular end face where burrs are concentrated, requiring only supplementary processing of the sidewall circumference afterward. Since the circumferential surface area of ​​the sidewall of the wear-resistant sheet 23 is much smaller than that of the circular end face, prioritizing the processing of the end face can significantly improve deburring efficiency, meeting the industrial production requirements for efficient deburring of the wear-resistant sheet surface.

[0033] In addition, the main references Figure 4 As shown, a positioning block 14 is installed on the top side wall of the positioning arm 13. The positioning block 14 is an elastic body with its own elasticity. In this application, the positioning block 14 is made of silicone rubber. It can deform when it clamps the side wall of the wear-resistant plate 23 under the driving action of the positioning arm 13, so as to balance the displacement difference between the rotating positioning arm 13 and the side wall of the wear-resistant plate 23. When the positioning arm 13 disengages from positioning the side wall of the wear-resistant plate 23, the positioning block 14 disengages from the wear-resistant plate 23 and automatically returns to its initial shape. The positioning block 14 is made of materials commonly used in the market, which can meet the above-mentioned usage requirements. No further description or limitation is required here.

[0034] In addition, the main references Figure 5 As shown, a support tray 22 is fixedly installed at the top of the support column 6, and the center of the support tray 22 is coaxial with the center of the support column 6. The wear-resistant sheet 23 is placed on the support tray 22. Through multiple circumferential positioning arms 13, the wear-resistant sheet 23 can be concentrically positioned at the top of the support tray 22, and the support tray 22 provides a support position for the initial placement of the wear-resistant sheet 23.

[0035] Main references Figures 3 to 5 As shown, the positioning arm 13 is driven by a linkage assembly, which includes: a second fixed seat 15, a mounting plate 16, a movable arm 17, a second U-shaped seat 18, a slide groove 19, a spring 20, and a drive pin 21. The second fixed seat 15 is fixedly mounted on the support column 6 and is located below the first fixed seat 9. Multiple mounting plates 16 are provided, and these plates are equidistantly positioned below the second fixed seat 15. Specifically, four mounting plates 16 are provided, and each of the four mounting plates 16 is fixed and vertically mounted on the lower surface of the second fixed seat 15. The movable arm 17 slides through the side wall of the mounting plate 16 and slides in contact with the side wall of the drive seat 8. The mounting plate 16 limits the directional movement of the movable arm 17. The vertical movement of the drive seat 8 enables the horizontal displacement of the moving arm 17. The second U-shaped seat 18 is fixedly installed on the end of the moving arm 17 away from the drive seat 8. The slide groove 19 is vertically opened on the side wall of the second U-shaped seat 18. The spring 20 is sleeved on the moving arm 17, and the two ends of the spring 20 are fixedly connected to the mounting plate 16 and the second U-shaped seat 18 respectively. The drive pin 21 is slidably embedded in the inner cavity of the slide groove 19, and the drive pin 21 is rotatably connected to the bottom free end of the positioning arm 13 through a bearing. The connecting arm 10 is arranged parallel to the moving arm 17, thereby ensuring that when the moving arm 17 is displaced, it drives the positioning arm 13 to rotate accurately around the rotating shaft 12, avoiding the situation where the moving arm 17 cannot drive the positioning arm 13 due to an inaccurate drive path.

[0036] Specifically, after the first cylinder 7 is activated, the drive seat 8 moves upward along the support column 6. Since the drive seat 8 is a frustum structure, narrow at the top and wide at the bottom, its upward movement pushes multiple sets of circumferentially moving arms 17 outward, stretching the spring 20. The outwardly moving arms 17 drive the second U-shaped seat 18 to move outward synchronously, causing the drive pin 21 to slide along the inner cavity of the slide groove 19. Simultaneously, the drive pin 21 drives the positioning arm 13 to rotate inward around the pivot 12, engaging with it, so that the positioning block 14 at the end of the positioning arm 13 is close to the side wall of the wear-resistant sheet 23. Through the synchronous rotation and engagement of multiple circumferentially evenly arranged positioning arms 13 and positioning blocks 14 towards the center, the wear-resistant sheet 23 is centrally positioned and clamped at the top of the support tray 22.

[0037] This invention utilizes the coordinated operation of components such as the drive seat 8, the moving arm 17, and the drive pin 21 to enable multiple sets of positioning arms 13 to rotate synchronously and engage with the side wall of the wear-resistant sheet 23, thereby achieving circumferential positioning of the wear-resistant sheet 23. This positioning method eliminates the need for individual driving of each positioning unit, ensuring strong synchronization and guaranteeing that the wear-resistant sheet 23 is precisely centered on the support tray 22. This, in turn, ensures the positional accuracy of the wear-resistant sheet 23 relative to the grinding station of the grinding plate 26, providing a reliable benchmark for subsequent deburring processing.

[0038] Furthermore, in this invention, when the drive seat 8 moves upward, it can drive multiple sets of positioning arms 13 to rotate inward synchronously and engage the side wall of the wear-resistant plate 23 to complete the positioning; when the drive seat 8 moves downward, the positioning arms 13 rotate in the opposite direction to disengage from the positioning by means of the elastic force of each spring 20. That is, the positioning adjustment of the wear-resistant plate 23 by multiple sets of positioning arms 13 is achieved by the lifting and lowering movement of the drive seat 8. The positioning state can be switched with only the linear movement of a single component, eliminating the need for a complex multi-drive system, reducing the manufacturing cost and maintenance difficulty of the equipment, and making it more practical.

[0039] For details, please refer to the main references. Figure 2 and Figure 4 As shown, the outer wall of the end of the movable arm 17 near the drive seat 8 has an arc-shaped structure. Compared with the free end of the movable arm 17 which is set at a right angle, it can better ensure that the drive seat 8, which moves vertically, drives the movable arm 17 to achieve relative movement more smoothly.

[0040] Main references Figure 1 , Figure 2 , Figure 4 As shown, the turntable 5 rotates circumferentially through a drive assembly, which includes a through hole 2, a motor frame 3, and a drive motor 4. The through hole 2 is opened through the middle of the platform 1 from top to bottom. The motor frame 3 is fixedly installed at the bottom of the platform 1. The drive motor 4 is installed inside the motor frame 3, and the output end of the drive motor 4 is fixedly connected to the middle of the bottom of the turntable 5. The drive motor 4 drives the turntable 5, the support column 6, and the positioned wear-resistant plate 23 to rotate synchronously in the circumferential direction, which helps to realize the subsequent grinding process of the wear-resistant plate 23.

[0041] Main references Figure 1 , Figure 6As shown, this solution also includes a grinding assembly, which includes: a bracket 24, a second cylinder 25, and a grinding plate 26. The bracket 24 is fixedly installed on the rear side wall of the frame 1; the second cylinder 25 is installed on the top of the bracket 24; the grinding plate 26 is installed at the bottom output end of the second cylinder 25. The grinding plate 26 is a commonly used grinding material in the market, which can be detachably installed at the output end of the second cylinder 25 by means of bolts and nuts, making it easy to replace the corresponding grinding plate 26 according to different grinding needs, and also facilitating the use of... The grinding plate 26 is replaced after a period of time; the model of the existing parts is not limited or described in detail here; the drive motor 4 drives the turntable 5, the support column 6 and the positioned wear-resistant plate 23 to rotate synchronously. At the same time, the second cylinder 25 drives the grinding plate 26 to move downward so that it fits against the upper surface of the wear-resistant plate 23. Based on the relative friction between the rotation of the wear-resistant plate 23 and the lower surface of the grinding plate 26, the burr removal treatment of the circumferential end face of the wear-resistant plate 23 is achieved in all directions without dead angles.

[0042] This invention employs a mode where the workpiece wear-resistant plate 23 rotates while the grinding plate 26 remains stationary, relying on relative friction to complete deburring. Compared to the traditional method of rotating the grinding part, this setup can precisely control the friction trajectory, ensure uniform force distribution, effectively avoid centrifugal force loss and vibration interference, and significantly improve deburring efficiency and workpiece surface processing accuracy.

[0043] For details, please refer to the main references. Figure 3 As shown, the length of the grinding plate 26 is greater than the radius of the wear-resistant sheet 23, so that the circumferential end face of the wear-resistant sheet 23 can be completely ground by the grinding plate 26 when it rotates, avoiding burr residue caused by insufficient grinding length in traditional processes, and ensuring a comprehensive and thorough deburring effect.

[0044] In addition, when the wear-resistant sheet 23 needs to be disassembled or flipped for grinding after grinding, the drive seat 8 is driven to move downward by the output end of the first cylinder 7, which releases the pushing force on the moving arm 17. At this time, the moving arm 17 automatically retracts inward under the elastic force of the spring 20, which drives the drive pin 21 to rotate the positioning arm 13 outward. The positioning block 14 at the end of the positioning arm 13 moves away from the outer wall of the wear-resistant sheet 23. All positioning arms 13 and positioning blocks 14 release the limiting constraints on the wear-resistant sheet 23, thereby meeting the process requirements for flipping or disassembling the wear-resistant sheet 23.

[0045] It is worth noting that the first cylinder 7 and the second cylinder 25 used in this application are commonly used self-locking cylinders on the market. Their output ends can stop at any position and be locked. They are existing equipment. The air supply system for supplying air to the first cylinder 7 is set on the upper surface of the turntable 5. Under the rotation of the turntable 5, the turntable 5 can be driven to rotate synchronously with the first cylinder 7 and the air supply system of the first cylinder 7, eliminating the situation where the air supply pipe of the air supply system is entangled with the first cylinder 7. The drive motor 4 is a commonly used self-locking motor on the market whose output end can be locked. When it stops, its output end can be self-locked and will not rotate under external force. The drive motor 4 is a commonly used forward and reverse motor on the market. Its output end can rotate forward or reverse according to the usage requirements. It can meet the above usage requirements. With the forward and reverse rotation of the output end of the drive motor 4, the wear-resistant plate 23 can be freely selected for grinding in the forward and reverse directions. And through the forward and reverse rotation of the wear-resistant plate 23, the situation of incomplete deburring caused by unidirectional rotation is eliminated.

[0046] The working principle of the deburring device for producing wear-resistant sheets in this embodiment is as follows:

[0047] Place the wear-resistant sheet 23 on the support tray 22 and start the first cylinder 7 to drive the drive seat 8 to move upward along the support column 6. Since the drive seat 8 is a frustum shape that is narrow at the top and wide at the bottom, when it moves upward, it pushes multiple sets of circumferential moving arms 17 to move outward, causing the spring 20 to be stretched. The outward moving arms 17 drive the second U-shaped seat 18 to move outward synchronously, causing the drive pin 21 to slide along the inner cavity of the slide groove 19. At the same time, the drive pin 21 drives the positioning arm 13 to rotate inward around the pivot 12 and engage, so that the positioning block 14 at the end of the positioning arm 13 is close to the side wall of the wear-resistant sheet 23. Through the circumferentially evenly arranged multiple sets of positioning arms 13 and positioning blocks 14 rotating and engaging towards the center synchronously, the wear-resistant sheet 23 is centered and clamped at the top of the support tray 22.

[0048] The drive motor 4 drives the turntable 5, support column 6 and the positioned wear-resistant plate 23 to rotate synchronously in the circumferential direction. At the same time, the second cylinder 25 drives the grinding plate 26 to move down and fit against the upper surface of the wear-resistant plate 23. By utilizing the rotation of the wear-resistant plate 23 and the relative friction between the lower surface of the grinding plate 26 and the lower surface of the grinding plate 26, the circumferential end face of the wear-resistant plate 23 is fully deburred.

[0049] This invention uses multiple sets of positioning arms 13 to evenly position the sidewalls of the wear-resistant sheet 23 circumferentially, prioritizing concentrated grinding of the circular end face where burrs are concentrated, thus significantly improving deburring efficiency. Synchronous positioning of the multiple positioning arms 13 through component collaboration ensures accurate centering and provides a reliable benchmark for subsequent processing. Positioning adjustment is achieved solely through the lifting and lowering of the drive seat 8, simplifying the structure and reducing costs and maintenance difficulty. The deburring mode employing the rotation of the wear-resistant sheet 23 while the grinding plate 26 remains stationary precisely controls the friction path and force, improving efficiency and quality. Setting the length of the grinding plate 26 to be greater than the radius of the wear-resistant sheet 23 ensures comprehensive grinding coverage and eliminates the risk of burr residue.
