[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a surface grinding device for spherical metal parts, which has the advantages of requiring less manual intervention and greatly improving grinding efficiency. It solves the problem in the existing technology that grinding spherical metal parts involves clamping the spherical metal parts with a clamp and manually operating a grinding machine to grind the spherical metal parts, and manual adjustment is required when adjusting the grinding surface, resulting in excessive manual intervention and reduced grinding efficiency.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A surface grinding device for spherical metal parts includes a rectangular shell and a metal ball. A hemispherical shell extending into and flush with the top of the rectangular shell is embedded in the top of the rectangular shell. The hemispherical shell is adapted to the metal ball. A ring-shaped array of ball bearings is embedded in the inner wall of the hemispherical shell and movably connected thereto. The opposite sides of each ball bearing are in contact with the metal ball. A rubber transmission ball extending below the bottom wall of the hemispherical shell is movably connected. The top of the rubber transmission ball is in contact with the metal ball. A support plate is fixedly connected to the bottom wall of the inner cavity of the rectangular shell. The inner sidewall of the rectangular shell is provided with a connection to the support plate and... The drive assembly has rubber transmission balls in contact with each other. The top of the rectangular housing is provided with limiting components arranged in a ring array and located on the periphery of the hemispherical shell. The opposite side of each limiting component is adapted to a metal ball. A rectangular frame is fixedly connected to the top of the rectangular housing. A motor with its output end extending into the rectangular frame is fixedly connected to the top of the rectangular frame. A third electric push rod, symmetrically distributed on both sides and with its output end extending into the rectangular frame, is fixedly connected to the top of the rectangular frame. The output end of the third electric push rod is fixedly connected to the same frame plate. The output end of the motor is connected to a sleeve that is rotatably connected to the frame plate. A friction assembly is provided on the outside of the sleeve, located below it and adapted to the metal ball.

[0008] The beneficial effects of this utility model are:

[0009] This surface grinding equipment for spherical metal parts places a metal ball into a hemispherical shell. At this point, both the ball bearings and the rubber transmission ball are in contact with the metal ball, causing the limiting component to move to its opposite side until both sides of the limiting component are tightly fitted to the outer side of the metal ball, thus limiting the metal ball. The friction component is adjusted to fit the metal ball, causing the output end of the third electric push rod to move the frame plate towards the metal ball. This causes the sleeve to slide towards the metal ball from the outside of the motor output end until the friction component contacts the metal ball, thus activating the motor. The motor output end drives the friction component to rotate through the sleeve, thus grinding the metal ball. When it is necessary to adjust the grinding surface of the metal ball, the limiting component moves to its opposite side, releasing the limitation on the metal ball and activating the drive component. The rubber transmission ball then moves the metal ball within the hemispherical shell. The ball bearings on the inner wall of the hemispherical shell facilitate the movement of the metal ball within the shell. This equipment has the advantages of requiring less manual intervention in grinding and adjusting the grinding surface, and greatly improving grinding efficiency.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the limiting component includes a second electric slide bar, a contact block, and a rubber pad. The top of the rectangular shell is provided with a second electric slide bar arranged in a circular array and located on the periphery of the hemispherical shell. The output end of each of the second electric slide bars is fixedly connected to a contact block, and a rubber pad adapted to the metal ball is fixedly connected to the opposite side of each contact block.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by placing the metal ball into the hemispherical shell, the output ends of the second electric slide rods move to their opposite sides, thereby driving the contact blocks to move closer to the metal ball until the opposite sides of the rubber pads are in close contact with the outer surface of the metal ball, thus limiting the position of the metal ball inside the hemispherical shell.

[0013] Furthermore, the friction assembly includes a connecting rod, a side rod, a dorsal fin spring plate, polishing paper, a connecting seat, a lead screw, and an internally threaded cylinder. The outer side of the sleeve is hinged with connecting rods that are symmetrically distributed from left to right. The lower end of each connecting rod is hinged with a side rod. The lower end of each side rod is fixedly connected to the same dorsal fin spring plate located below the sleeve. The bottom of the dorsal fin spring plate is fixedly connected with polishing paper that is compatible with the metal ball. A connecting seat is hinged to the opposite side of the lower end of each connecting rod. A lead screw is fixedly connected to the opposite side of each connecting seat. The thread direction of the lead screw on the left side is opposite to that of the lead screw on the right side. The opposite side of each lead screw is threaded with the same internally threaded cylinder.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, when the internal threaded cylinder is rotated, since the thread directions of the left and right lead screws are opposite, the connecting seat can be driven to move synchronously to the opposite or opposite side through the lead screw. When the connecting seat moves synchronously to the opposite side, it pushes the connecting rod and the side rod to unfold outward, and at the same time applies a squeezing force to the dorsal fin spring plate, so that the bottom of the dorsal fin spring plate bends upward to form an arc until the curvature of the sanding paper matches the metal ball.

[0015] Furthermore, the driving assembly includes a frame-shaped slide rail, a slider, a first electric push rod, and a contact plate. The inner cavity sidewall of the rectangular housing is fixedly connected to the frame-shaped slide rail. Sliders are slidably connected to the four sides of the frame-shaped slide rail. A first electric push rod is provided on each opposite side of the slider. The output end of the first electric push rod is fixedly connected to the same contact plate. The top of the contact plate contacts the rubber transmission ball, and the bottom of the contact plate contacts the support plate.

[0016] Furthermore, grease is applied between the top of the support plate and the contact plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation between the relative first electric push rods, when the output end of the first electric push rod in the lateral direction drives the contact plate to move, the contact plate drives the first electric push rod in the longitudinal direction and the slider to slide laterally. Conversely, this drives the contact plate to complete the movement in the horizontal plane. The support plate supports the contact plate, and the grease on the surface of the support plate makes the movement of the contact plate smoother. Since the contact plate is in contact with the rubber transmission ball, and the rubber transmission ball is in contact with the metal ball, when the contact plate moves horizontally, the rubber transmission ball drives the metal ball to move within the hemispherical shell, thus completing the adjustment of the grinding surface of the metal ball.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-5This invention discloses a surface polishing device for spherical metal parts. The device includes a rectangular housing 1 and a metal ball 2. A hemispherical shell 3, extending into and flush with the top of the rectangular housing 1, is embedded in the top of the rectangular housing 1. The hemispherical shell 3 is adapted to the metal ball 2. Roller balls 4, arranged in a circular array and movably connected to the inner wall of the hemispherical shell 3, are embedded therein. Opposite sides of each roller ball 4 are in contact with the metal ball 2. A rubber transmission ball 5, extending downwards, is movably connected to the bottom wall of the hemispherical shell 3. The top of the rubber transmission ball 5 is in contact with the metal ball 2. A support plate 6 is fixedly connected to the bottom wall of the inner cavity of the rectangular housing 1. A drive assembly, in contact with both the support plate 6 and the rubber transmission ball 5, is provided on the side wall of the inner cavity of the rectangular housing 1. Component 7, the top of the rectangular shell 1 is provided with limiting components 8 arranged in a ring array and located around the hemispherical shell 3. The opposite side of the limiting components 8 is adapted to the metal ball 2. The top of the rectangular shell 1 is fixedly connected to a rectangular frame 9. The top of the rectangular frame 9 is fixedly connected to a motor 10 with its output end extending into it. The top of the rectangular frame 9 is fixedly connected to a third electric push rod 11 arranged symmetrically on the left and right sides and with its output end extending into it. The output end of the third electric push rod 11 is fixedly connected to the same frame plate 12. The output end of the motor 10 is connected to a sleeve 13 that is rotatably connected to the frame plate 12. The outer side of the sleeve 13 is provided with a friction component 14 located below it and adapted to the metal ball 2.

[0026] The limiting component 8 includes a second electric slide bar 801, a contact block 802, and a rubber pad 803. The top of the rectangular housing 1 is provided with a second electric slide bar 801 arranged in a ring array and located around the hemispherical housing 3. The output ends of the second electric slide bar 801 are all fixedly connected to the contact block 802. The opposite side of the contact block 802 is fixedly connected to a rubber pad 803 adapted to the metal ball 2.

[0027] The metal ball 2 is placed inside the hemispherical shell 3, causing the output ends of the second electric slide bar 801 to move to their opposite sides, which in turn drives the contact blocks 802 to move closer to the metal ball 2 until the opposite sides of the rubber pad 803 are in close contact with the outer surface of the metal ball 2, thus limiting the position of the metal ball 2 inside the hemispherical shell 3.

[0028] The friction assembly 14 includes a connecting rod 141, a side rod 142, a dorsal fin spring plate 143, a polishing paper 144, a connecting seat 145, a lead screw 146, and an internally threaded cylinder 147. The outer side of the sleeve 13 is hinged with connecting rods 141 that are symmetrically distributed on the left and right. The lower end of each connecting rod 141 is hinged with a side rod 142. The lower end of each side rod 142 is fixedly connected with the same dorsal fin spring plate 143 located below the sleeve 13. The bottom of the dorsal fin spring plate 143 is fixedly connected with a polishing paper 144 that is compatible with the metal ball 2. The lower ends of each connecting rod 141 are hinged with connecting seats 145 on opposite sides. The opposite sides of each connecting seat 145 are fixedly connected with a lead screw 146. The thread direction of the lead screw 146 on the left side is opposite to that of the lead screw 146 on the right side. The opposite sides of the lead screw 146 are threaded with the same internally threaded cylinder 147.

[0029] Rotating the internal threaded cylinder 147, since the thread directions of the left lead screw 146 and the right lead screw 146 are opposite, the connecting seat 145 can be driven to move synchronously to the opposite or opposite side through the lead screw 146. When the connecting seat 145 moves synchronously to the opposite side, it will push the connecting rod 141 and the side rod 142 to unfold outward, and at the same time apply a squeezing force to the dorsal fin spring plate 143, so that the bottom of the dorsal fin spring plate 143 bends upward to form an arc until the curvature of the polishing paper 144 matches the metal ball 2.

[0030] The drive assembly 7 includes a frame-type slide rail 701, a slider 702, a first electric push rod 703, and a contact plate 704. The frame-type slide rail 701 is fixedly connected to the inner cavity sidewall of the rectangular housing 1. The slider 702 is slidably connected to all four sides of the frame-type slide rail 701. The first electric push rod 703 is provided on the opposite side of each slider 702. The output end of the first electric push rod 703 is fixedly connected to the same contact plate 704. The top of the contact plate 704 contacts the rubber transmission ball 5, and the bottom of the contact plate 704 contacts the support plate 6.

[0031] Lubricating grease is applied between the top of the support plate 6 and the contact plate 704.

[0032] Through the cooperation between the relative first electric push rods 703, when the output end of the transverse first electric push rod 703 drives the contact plate 704 to move, the contact plate 704 drives the longitudinal first electric push rod 703 and the slider 702 to slide laterally. Conversely, this drives the contact plate 704 to complete the movement in the horizontal plane. The support plate 6 supports the contact plate 704, and the grease on the surface of the support plate 6 makes the movement of the contact plate 704 smoother. Since the contact plate 704 is in contact with the rubber transmission ball 5, and the rubber transmission ball 5 is in contact with the metal ball 2, when the contact plate 704 moves horizontally, the rubber transmission ball 5 drives the metal ball 2 to move in the hemispherical shell 3, thus completing the adjustment of the grinding surface of the metal ball 2.

[0033] Working principle:

[0034] Step 1: Place the metal ball 2 into the hemispherical shell 3. At this time, the ball bearing 4 and the rubber transmission ball 5 are in contact with the metal ball 2, causing the output end of the second electric slide bar 801 to move to its opposite side. This then drives the contact blocks 802 to move closer to the metal ball 2 until the opposite side of the rubber pad 803 is in close contact with the outer surface of the metal ball 2, thus limiting the position of the metal ball 2 inside the hemispherical shell 3.

[0035] Step 2: Rotate the internal threaded cylinder 147. Since the thread directions of the left lead screw 146 and the right lead screw 146 are opposite, the lead screw 146 can drive the connecting seat 145 to move synchronously to the opposite or opposite side. When the connecting seat 145 moves synchronously to the opposite side, it pushes the connecting rod 141 and the side rod 142 to unfold outward, and at the same time applies a squeezing force to the dorsal fin spring plate 143, so that the bottom of the dorsal fin spring plate 143 bends upward to form an arc until the curvature of the polishing paper 144 matches the metal ball 2. This causes the output end of the third electric push rod 11 to drive the frame plate 12 to move towards the metal ball 2, thereby driving the sleeve 13 to slide towards the metal ball 2 on the outside of the output end of the motor 10 until the polishing paper 144 contacts the metal ball 2, thereby making the motor 10 operate. The output end of the motor 10 drives the dorsal fin spring plate 143 and the polishing paper 144 to rotate through the sleeve 13, which can polish the metal ball 2.

[0036] Step 3: When it is necessary to adjust the grinding surface of the metal ball 2, the output ends of the second electric slide rod 801 are moved to opposite sides, which in turn causes the contact block 802 and the rubber pad 803 to separate from the metal ball 2, thus releasing the restriction on the metal ball 2. Through the cooperation between the relative first electric push rods 703, when the output end of the first electric push rod 703 moves laterally, it drives the contact plate 704 to move. The contact plate 704 drives the first electric push rod 703 and the slider 702 to slide laterally. Conversely, it drives the contact plate 704 to complete the horizontal movement. The support plate 6 supports the contact plate 704, and the grease on the surface of the support plate 6 makes the movement of the contact plate 704 smoother. Since the contact plate 704 is in contact with the rubber transmission ball 5, and the rubber transmission ball 5 is in contact with the metal ball 2, when the contact plate 704 moves horizontally, the rubber transmission ball 5 drives the metal ball 2 to move within the hemispherical shell 3, thus completing the adjustment of the grinding surface of the metal ball 2.
