Description

Technical Field

[0001] This invention relates to the field of surface grinding technology, specifically to a special surface grinding machine for the side of thin plates with dynamic precision feed. Background Technology

[0002] A surface grinder is a type of grinding machine that uses a rotating grinding wheel to grind workpieces to achieve the required flatness. Based on the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable surface grinder are the width and length of the worktable, while the main parameter of a circular worktable is the diameter of the worktable surface. Based on the type of shaft, it can be divided into horizontal spindle grinders and vertical spindle grinders.

[0003] A search revealed that in the prior art, CN215239783U discloses a dynamic precision feed surface grinder for thin plates. This grinder includes a grinder body with an annular mounting groove on its upper surface and symmetrically distributed limiting grooves on the inner wall of the groove. This dynamic precision feed surface grinder for thin plates utilizes a thin plate fixing device on the inner top wall of the annular mounting groove. The thin plate fixing device includes a first servo motor, the lower surface of which is fixedly mounted to the center of the inner bottom wall of the annular mounting groove. This achieves the fixation of non-magnetic thin plates and improves grinding efficiency. It solves the problem that existing surface grinders, when grinding some non-magnetic thin plates, require the ends of the clamp to be higher than the upper surface to hold the workpiece, resulting in obstructed grinding and low grinding efficiency.

[0004] In the above technical solution, when grinding thin plate workpieces, the grinding machine can easily grind the edges and sides of the workpieces because the workpieces are thin. Furthermore, the grinding machine surface can obstruct the grinding of the bottom of the thin plate, resulting in poor grinding effect. Therefore, we propose a special surface grinder for thin plate sides with dynamic precision feed. Summary of the Invention

[0020] Beneficial effects

[0021] This invention provides a special surface grinder for the side surfaces of thin plates with dynamic precision feed. It has the following advantages:

[0022] When the circular plate inside the circular cavity is in the lifting state, the sliding connection between the spline grooves can transmit power to the circular plate in the lifting state, so that the servo motor can drive the circular plate to rotate. This allows the circular plate to adjust the grinding angle of the workpiece while it is in the lifting state, improving the automation performance of the equipment and avoiding the phenomenon of manual adjustment by the operator.

[0023] The electric push rod can drive the guide block to slide up and down inside the guide seat. The guide block can drive the ring frame to move upward. Several rollers rise and connect with the lower surface of the circular plate, thereby pushing the circular plate to the lifting state. This lifts the thin plate workpiece fixed on the upper side of the circular plate away from the surface of the support plate, avoiding the phenomenon that the support plate blocks the grinding disc from contacting the lower part of the workpiece's edges and corners, thus improving the grinding effect of the equipment on the sides and edges and corners.

[0024] The circular electric guide rail drives the movable baffle to move around it, thereby driving the first and second housings to move. When the first housing is switched to face downwards, it is in the surface grinding state. The lifting electric slide rail moves downwards, causing the lower end of the first baffle located inside the first housing to contact the surface of the workpiece. As the lifting electric slide rail continues to move downwards, the first housing and the first baffle move relative to each other. The vertical spring applies pressure to press the first baffle tightly against the surface of the thin workpiece, forming a protective storage structure during grinding to prevent sparks and impurities from splashing and improve the safety of the equipment.

[0025] Activating the circular electric guide rail drives the movable baffle to move around it, thereby driving the first and second housings to move. When the second housing is switched to face directly downwards, it is in the side grinding state. Activating the horizontal electric slide rail drives the thin plate workpiece to move towards the side opening of the second baffle side wall. During this movement, the side wall of the thin plate workpiece first disengages from the second baffle. As the horizontal electric slide rail continues to move, the second housing moves relative to the second baffle. The horizontal spring applies pressure to press the second baffle tightly against the side of the thin plate workpiece, forming a protective storage structure when grinding the side wall, preventing sparks and impurities from splashing and improving the safety of the equipment.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example:

[0042] like Figures 1-13 As shown, this embodiment of the invention provides a special surface grinder for the side of thin plates with dynamic precision cutting, including a grinding table 1, a moving adjustment component 2 mounted on the upper surface of the grinding table 1, a support plate 3 mounted on the upper side of the moving adjustment component 2, a circular cavity 31 with the upper surface of the support plate 3 facing downward, a servo motor 32 mounted in the center of the circular cavity 31, a spline shaft 33 fixedly mounted on the output end of the servo motor 32, a connecting shaft 35 provided on the upper end of the spline shaft 33, a circular plate 4 fixedly connected to the upper end of the connecting shaft 35, and the circular plate 4 rotatably mounted inside the circular cavity 31;

[0043] A spline groove 34 is provided at the center of the lower end of the connecting shaft 35. The upper end of the spline shaft 33 slides into the spline groove 34. When the circular plate 4 inside the circular cavity 31 is in the lifting state, the connection between the spline grooves 34 and the spline groove 34 can transmit power to the circular plate 4 in the lifting state, so that the servo motor 32 can drive the circular plate 4 to rotate. This allows the circular plate 4 to adjust the grinding angle of the workpiece in the lifting state, improving the automation performance of the equipment and avoiding the phenomenon of manual adjustment by the operator.

[0044] Inside the circular cavity 31, a guide seat 37 is fixedly installed outside the servo motor 32. Several guide blocks 36 are slidably installed inside the guide seat 37 in the up-down direction. A ring frame 38 is fixedly installed on the upper end of the guide block 36. Several rollers 39 that abut against the circular plate 4 are rotatably installed on the upper end of the ring frame 38 through a bracket. An electric push rod 361 is fixedly installed inside the guide seat 37 below the guide block 36. The output end of the electric push rod 361 is fixedly connected to the guide block 36. The electric push rod 361 can drive the guide block 36 to slide up and down inside the guide seat 37. Through the guide block 36, the ring frame 38 can be driven to move upward. The rollers 39 rise and connect with the lower surface of the circular plate 4, thereby pushing the circular plate 4 to the lifting state. The thin plate workpiece fixed on the upper side of the circular plate 4 is lifted away from the surface of the support plate 3, avoiding the phenomenon that the support plate 3 blocks the grinding disc 8 from contacting the lower part of the workpiece's edge and corner, thus improving the grinding effect of the equipment on the side and edge.

[0045] In this embodiment, a support frame 5 is installed on the upper surface of the grinding machine worktable 1 on one side of the movable adjustment component 2. A lifting electric slide rail 6 is fixedly installed on the side of the support frame 5 near the movable adjustment component 2. A grinding motor 7 is fixedly installed on the moving end of the lifting electric slide rail 6. A grinding disc 8 is installed on the output end of the grinding motor 7. A protective component 9 is installed on the outer side of the grinding disc 8.

[0046] In this embodiment, the protective component 9 includes a fixed housing 91 and a housing cover 92. The fixed housing 91 is located on the side of the grinding disc 8 near the grinding motor 7 and is fixedly installed on the outer casing of the grinding motor 7. The housing cover 92 is located on the side of the grinding disc 8 away from the grinding motor 7 and is detachably installed on the fixed housing 91 by bolts. The housing cover 92 is detachably installed on the fixed housing 91 by bolts, which facilitates the removal of the housing cover 92 by the operator to replace the internal grinding disc 8. The housing cover 92 and the fixed housing 91 form a protective cover surrounding the grinding disc 8, which can provide protection during the grinding process, prevent objects from accidentally touching the grinding disc 8 and causing safety accidents, and improve the safety of the equipment during operation.

[0047] In this embodiment, an arc-shaped groove 93 is provided on the lower edge of the outer surface of the housing cover plate 92 and the fixed housing 91. A movable baffle 94 is provided inside the arc-shaped groove 93. The width of the movable baffle 94 is smaller than the inner width of the arc-shaped groove 93, so that the movable baffle 94 can slide into the interior of the housing cover plate 92 and the fixed housing 91 through the arc-shaped groove 93, thereby adjusting the surface grinding mode or the edge grinding mode of the equipment. The movable baffle 94 is used to block the arc-shaped groove 93 to prevent the material and sparks generated during grinding from falling to the outside. Side plates extend from both sides of the movable baffle 94 toward the center of the fixed housing 91. The side plates and the movable baffle 94 form a groove shape, which can collect impurities and prevent impurities from falling.

[0048] In this embodiment, a circular electric guide rail 95 is fixedly installed on the inner wall of the fixed housing 91. The circular electric guide rail 95 is concentrically arranged with the fixed housing 91. The moving end of the circular electric guide rail 95 is fixedly connected to the movable baffle 94. A first box 96 and a second box 97 are provided outwardly on the outer wall of the movable baffle 94. The edge of the frosting disc 8 extends into the groove formed by the side plate and the movable baffle 94, and into the interior of the first box 96 and the second box 97. The first box 96 and the second box 97 both penetrate the movable baffle 94 and are fixedly connected to the movable baffle 94. Activating the circular electric guide rail 95 enables… The movable baffle 94 is driven to move around it, thereby driving the first box 96 and the second box 97 to move. When the first box 96 is switched to face downwards, it is in the surface grinding state. The lifting electric slide rail 6 moves downwards, which can drive the lower end of the first baffle 961 located inside the first box 96 to contact the surface of the workpiece. When the lifting electric slide rail 6 continues to move downwards, the first box 96 and the first baffle 961 move relative to each other. The vertical spring 965 applies pressure to press the first baffle 961 tightly against the surface of the thin plate workpiece, forming a protective storage structure during grinding to avoid sparks and impurities from splashing and improve the safety of the equipment.

[0049] Activating the circular electric guide rail 95 drives the movable baffle 94 to move around it, thereby driving the first box 96 and the second box 97 to move. When the second box 97 is switched to face directly downwards, it is in the side grinding state. Activating the horizontal electric slide rail 22 drives the thin plate workpiece to move towards the side opening 972 of the side wall of the second baffle 971. During this movement, the side wall of the thin plate workpiece first contacts the second baffle 971. As the horizontal electric slide rail 22 continues to move, the second box 97 and the second baffle 971 move relative to each other. The horizontal spring 976 applies pressure to press the second baffle 971 against the side of the thin plate workpiece, forming a protective storage structure when grinding the side wall, avoiding sparks and impurities from splashing, and improving the safety of the equipment.

[0050] In this embodiment, a first baffle 961 is provided inside the first box 96 along its inner edge. The first baffle 961 is closed on all four sides, with openings at the top and bottom. When the first baffle 961 moves, the edge of the grinding disc 8 passes through the upper opening of the first baffle 961 and moves into the interior of the first baffle 961, and passes through the lower opening of the first baffle 961 to perform grinding work on the thin plate workpiece. Several vertical grooves 963 are vertically opened on the inner wall of the first box 96. A vertical slider 964 is slidably installed inside the vertical grooves 963. The first baffle 961 can move along the vertical grooves 963 via the vertical slider 964. The vertical slider 964 is fixedly installed on the outer wall of the first baffle 961. A vertical spring 965 is fixedly installed at the upper end of the vertical slider 964. The vertical spring 965 can apply pressure to the first baffle 961, so that the first baffle 961 contacts the workpiece surface. The vertical spring 965 is installed inside the vertical grooves 963.

[0051] In this embodiment, a second baffle 971 is provided inside the second box 97. Side openings 972 are provided on the upper side and the side near the grinding motor 7 of the second baffle 971. The two side openings 972 are connected, so that the side of the workpiece can pass through the connecting part and contact the grinding disc 8 inside the second baffle 971 for grinding. A transverse groove 974 is provided on the inner wall of the second box 97. A transverse slider 975 is slidably installed inside the transverse groove 974. One side of the transverse slider 975 is fixedly installed on the outer wall of the second baffle 971. The second baffle 971 can move laterally along the transverse groove 974 through the transverse slider 975. A transverse spring 976 is fixedly installed at the end of the transverse slider 975 away from the grinding motor 7. The transverse spring 976 is installed inside the transverse groove 974. The transverse spring 976 can apply pressure to the second baffle 971, so that the second baffle 971 contacts the surface of the workpiece.

[0052] In this embodiment, a filter box 10 is installed on the upper surface of the grinding machine worktable 1. A negative pressure air pump 12 is installed at one end of the filter box 10 and connected to one end of the filter box 10. A filter screen 11 is installed inside the filter box 10. An air pipe 13 is connected to the other end of the filter box 10. Several first air pipes 962 and several second air pipes 973 are respectively connected to the end of the air pipe 13. Several first air pipes 962 are connected to the inside of a first baffle 961, and several second air pipes 973 are connected to the inside of a second baffle 971. The negative pressure air pump 12... The filter box 10 can generate negative pressure, which in turn generates suction inside the air pipe 13. This suction causes the first air pipes 962 and the second air pipes 973 installed on the second baffle 971 and the first baffle 961 to flow air. This can collect the dust generated during grinding and collected inside the first baffle 961 and the second baffle 971, preventing it from accumulating on the workpiece surface or inside the equipment, thus improving the self-cleaning ability of the equipment. Furthermore, the negative pressure can accelerate the airflow, thereby improving the cooling effect of the grinding part.

[0053] In this embodiment, the movable adjustment component 2 includes a base plate 21, which is fixedly mounted on the upper surface of the grinding machine worktable 1. A transverse electric slide rail 22 is fixedly mounted on the upper surface of the base plate 21. A top plate 23 is fixedly mounted on the movable end of the transverse electric slide rail 22. A longitudinal electric slide rail 24 is fixedly mounted on the upper surface of the top plate 23. The movable end of the longitudinal electric slide rail 24 is fixedly connected to the support plate 3. In use, the transverse electric slide rail 22 can drive the support plate 3 to move laterally, and the longitudinal electric slide rail 24 can drive the support plate 3 to move longitudinally, thereby adjusting the position of the workpiece to be ground.

[0054] In this embodiment, a mounting groove 41 is provided on the upper surface of the circular plate 4. Magnetic fasteners 42 are installed inside both the mounting groove 41 and the support plate 3. By installing the magnetic fasteners 42 inside the mounting groove 41 and the circular plate 4, magnetic force can be generated to fix the workpiece on the surface of the circular plate 4 and the support plate 3.

[0055] Working principle:

[0056] When the circular plate 4 inside the circular cavity 31 is in the lifting state, the sliding connection between the spline grooves 34 and the spline grooves 34 can transmit power to the circular plate 4 in the lifting state, so that the servo motor 32 can drive the circular plate 4 to rotate, and the circular plate 4 can adjust the grinding angle of the workpiece in the lifting state, thereby improving the automation performance of the equipment and avoiding the phenomenon of manual adjustment by the operator.

[0057] The electric push rod 361 can drive the guide block 36 to slide up and down inside the guide seat 37. The guide block 36 can drive the ring frame 38 to move upward. Several rollers 39 rise and connect with the lower surface of the circular plate 4, thereby pushing the circular plate 4 to the lifting state. The thin plate workpiece fixed on the upper side of the circular plate 4 is lifted away from the surface of the support plate 3, avoiding the phenomenon that the support plate 3 blocks the contact between the grinding disc 8 and the lower part of the workpiece corners, thus improving the grinding effect of the equipment on the sides and corners.

[0058] The circular electric guide rail 95 drives the movable baffle 94 to move around it, thereby driving the first box 96 and the second box 97 to move. When the first box 96 is switched to face downwards, it is in the surface grinding state. The lifting electric slide rail 6 moves downwards, which drives the lower end of the first baffle 961 located inside the first box 96 to contact the surface of the workpiece. As the lifting electric slide rail 6 continues to move downwards, the first box 96 and the first baffle 961 move relative to each other. The vertical spring 965 applies pressure to press the first baffle 961 tightly against the surface of the thin plate workpiece, forming a protective storage structure during grinding to prevent sparks and impurities from splashing and improve the safety of the equipment.

[0059] Activating the circular electric guide rail 95 drives the movable baffle 94 to move around it, thereby driving the first box 96 and the second box 97 to move. When the second box 97 is switched to face directly downwards, it is in the side grinding state. Activating the horizontal electric slide rail 22 drives the thin plate workpiece to move towards the side opening 972 of the side wall of the second baffle 971. During this movement, the side wall of the thin plate workpiece is first released from the second baffle 971. As the horizontal electric slide rail 22 continues to move, the second box 97 and the second baffle 971 move relative to each other. The horizontal spring 976 applies pressure to press the second baffle 971 against the side of the thin plate workpiece, forming a protective storage structure when grinding the side wall, avoiding sparks and impurities from splashing, and improving the safety of the equipment.

[0060] The negative pressure air pump 12 can generate negative pressure inside the filter box 10, thereby generating suction inside the air pipe 13. This suction causes the first air pipes 962 and the second air pipes 973 installed on the second baffle 971 and the first baffle 961 to drive airflow. This can collect the dust generated during grinding and collected inside the first baffle 961 and the second baffle 971, preventing it from accumulating on the workpiece surface or inside the equipment, thus improving the self-cleaning ability of the equipment. Furthermore, the negative pressure can accelerate airflow, thereby improving the cooling effect of the grinding part.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
