Description

Technical Field

[0001] This utility model relates to the field of steel ball processing technology, and in particular to a steel ball surface treatment device. Background Technology

[0002] In modern industrial systems, steel balls are widely used as core components in various types of machinery and equipment. From automobile transmission systems to bearings in precision instruments, from moving parts of machine tools to key devices in aerospace, the performance and quality of steel balls directly determine the operating accuracy, stability, and service life of the equipment.

[0003] Unpolished steel balls have numerous defects on their surface, such as tiny bumps, scratches, and machining lines. These surface imperfections not only increase the coefficient of friction during operation, leading to energy loss and heat generation, but also become stress concentration points, reducing the fatigue life of the steel balls and severely affecting their reliability under high load and high speed conditions.

[0004] Currently, some equipment on the market uses the traditional grinding wheel method. Since the steel ball is round, this grinding method makes it difficult to precisely control the amount of grinding, which can easily lead to uneven grinding on the surface of the steel ball and affect the consistency of product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel ball surface treatment device that solves the technical problem of difficulty in accurately controlling the grinding amount when using grinding wheels, resulting in uneven grinding of the steel ball surface and affecting the consistency of product quality, thereby achieving the goal of improving grinding quality.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steel ball surface treatment device, including a support frame installed on a placement table, a surface treatment mechanism for grinding the surface of the steel ball provided on the support frame, and a spraying mechanism for spraying grinding liquid onto the surface of the steel ball provided on the support frame.

[0007] The surface treatment mechanism includes a horizontal plate mounted on the back of a support frame, and a bidirectional motor mounted on the back of the horizontal plate. The output ends of the bidirectional motor are connected to lead screws, and each lead screw is threadedly connected to a threaded slide plate that is slidably connected to a guide groove opened on the horizontal plate. A rotating shaft is rotatably connected to a rotating hole opened on the threaded slide plate, and a ball grinding table for grinding the surface of the steel ball is installed at the inner end of the rotating shaft. A grinding motor that drives the rotating shaft to rotate is installed on the threaded slide plate. A swing assembly that drives the horizontal plate to swing left and right is provided on the support frame, and a fixing assembly for clamping and fixing the steel ball is provided on the placement platform.

[0008] A further improvement is that the swing assembly includes a rotating shaft rotatably connected to a rotating hole in the support frame, and the rear end of the rotating shaft is connected to a horizontal plate. A swing motor for driving the rotating shaft to rotate is installed on the support frame.

[0009] A further improvement is that the fixing component includes an electric lifting rod installed on the bottom surface of the support frame, and a top rod is installed on the placement platform directly below the electric lifting rod. Arc-shaped blocks are installed on the free end of the electric lifting rod and the top of the top rod. A rotary motor for driving the top rod to rotate is installed inside the placement platform, and a stop component is provided inside the free end of the electric lifting rod.

[0010] A further improvement is that the stopping component includes a compression spring installed on the top wall of a slot on the free end of the electric lifting rod, and a sliding rod that slides vertically and vertically within the slot is installed at the bottom of the compression spring, with the bottom of the sliding rod connected to an arc-shaped block. Electrical contacts are installed at the top of the sliding rod and on the top wall of the slot.

[0011] A further improvement is that the spraying mechanism includes a liquid storage tank installed on the top of the support frame, and a liquid outlet pipe is installed on the liquid outlet port of the liquid storage tank. A spray nozzle is installed at the bottom of the liquid outlet pipe, and an electric sealing valve is installed on the liquid outlet pipe.

[0012] A further improvement is that the side of the liquid storage tank is equipped with an observation window made of transparent tempered glass, and a liquid replenishment pipe is installed on the top of the liquid storage tank.

[0013] By employing the above technical solution, this utility model provides a steel ball surface treatment device, which has at least the following beneficial effects:

[0014] 1. This utility model uses a swing motor to drive the horizontal plate to swing left and right, which in turn drives the ball grinding table to swing left and right against the surface of the steel ball, thereby grinding the entire side of the steel ball. While improving grinding efficiency, swing grinding can also ensure the consistency of side grinding.

[0015] 2. This utility model uses an electric lifting rod to push the arc-shaped blocks down to fix the steel ball inside the two arc-shaped blocks, preventing the steel ball from moving with the grinding table during the grinding process. It also starts a rotating motor to drive the steel ball to rotate, and works with the up-and-down swinging grinding table to grind the steel ball thoroughly and evenly except for the contact area with the arc-shaped blocks.

[0016] 3. When the electric lifting rod moves down, it pushes the arc-shaped block at the bottom of the sliding rod to contact the surface of the steel ball. At this time, the sliding rod is forced to slide up and compress the spring until the two electrical contacts make contact and send an electrical signal. The electric lifting rod is then controlled by the central control panel to stop moving down. There is no need for the worker to manually operate the electric lifting rod to move down, which avoids the situation of pressing the steel ball too tightly or too loosely.

[0030] 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.

[0031] Example 1

[0032] Addressing the problem that existing grinding technologies using abrasive wheels struggle to precisely control the grinding amount, resulting in uneven grinding of steel balls and affecting product quality consistency, this embodiment provides a steel ball surface treatment device. Please refer to... Figures 1-5 This embodiment provides a steel ball surface treatment device that can improve grinding quality. The device includes a support frame 2 mounted on a placement platform 1. A surface treatment mechanism 3 for grinding the steel ball surface is mounted on the support frame 2. A spraying mechanism 4 for spraying grinding fluid onto the steel ball surface is also mounted on the support frame 2. The surface treatment mechanism 3 uniformly grinds the steel ball surface, ensuring consistent grinding and improving the quality of the grinding process. The grinding fluid from the spraying mechanism 4 further enhances the grinding quality.

[0033] Because existing technologies using grinding wheels are difficult to precisely control the grinding amount, resulting in uneven grinding of the steel ball surface and affecting product quality consistency, this device is equipped with a surface treatment mechanism 3. The surface treatment mechanism 3 includes a horizontal plate 31 installed on the back of the support frame 2, and a bidirectional motor 32 is installed on the back of the horizontal plate 31. The output ends of the bidirectional motor 32 are connected to lead screws 33, and each lead screw 33 is threadedly connected to a threaded slide plate 34 that is slidably connected to a guide groove opened on the horizontal plate 31. A rotating shaft 35 is rotatably connected to a rotating hole opened on the threaded slide plate 34, and a ball grinding table 36 for grinding the surface of the steel ball is installed at the inner end of the rotating shaft 35. A grinding motor 37 that drives the rotating shaft 35 to rotate is installed on the threaded slide plate 34. A swing assembly 38 that drives the horizontal plate 31 to swing left and right is provided on the support frame 2. A fixing assembly 39 that clamps and fixes the steel ball is provided on the placement table 1. After the steel ball is placed on the placement table 1, the bidirectional motor 32 is started to drive the lead screw 33 to rotate, which in turn drives the threaded slide plate 34 on the lead screw 33 to move relative to the guide groove, thereby driving the ball grinding table 36 to fit against the surface of the steel ball from both sides. Then, the grinding motor 37 is started to drive the rotating shaft 35 to rotate, which in turn drives the ball grinding table 36 to rotate, thereby grinding the steel ball from both sides and improving the grinding efficiency.

[0034] Since the ball grinding table 36 can only grind the area where the steel ball is in contact, it is easy to cause uneven grinding. Therefore, the device is also equipped with a swing assembly 38. The swing assembly 38 includes a rotating shaft 381 rotatably connected to a rotating hole in the support frame 2. The rear end of the rotating shaft 381 is connected to the horizontal plate 31. The support frame 2 is equipped with a swing motor 382 that drives the rotating shaft 381 to rotate. When the swing motor 382 is started, the rotating shaft 381 rotates forward and backward repeatedly, which in turn drives the horizontal plate 31 to swing forward and backward. This causes the ball grinding table 36 to swing left and right against the side of the steel ball for grinding, so as to grind the entire side of the steel ball. While improving grinding efficiency, swing grinding can also ensure the consistency of side grinding.

[0035] When the ball grinding table 36 is grinding the steel ball, it needs to be auxiliaryly fixed to prevent the steel ball from moving with the ball grinding table 36 and affecting the grinding work. Therefore, the device is also equipped with a fixing component 39. The fixing component 39 includes an electric lifting rod 391 installed on the bottom surface of the support frame 2, and a top rod 392 installed on the placement platform 1 directly below the electric lifting rod 391. Arc-shaped blocks 393 are installed on the free end of the electric lifting rod 391 and the top of the top rod 392. A rotary motor 394 that drives the top rod 392 to rotate is installed in the placement platform 1. A stop component 310 is provided in the free end of the electric lifting rod 391. After the steel ball is placed in the arc-shaped block 393 on the top rod 392, the electric lifting rod 391 is activated to push the arc-shaped block 393 at its bottom down to the surface of the steel ball, thereby fixing the steel ball in the two arc-shaped blocks 393. This prevents the steel ball from moving with the ball grinding table 36 during the grinding process. During the grinding process, the rotating motor 394 is activated to drive the steel ball in the arc-shaped block 393 to rotate. Together with the up-and-down swinging ball grinding table 36, the steel ball is thoroughly and evenly ground except for the contact area with the arc-shaped block 393. After the side is ground, the steel ball can be manually moved slightly to grind the remaining area, thereby ensuring the consistency of the grinding.

[0036] To improve the grinding effect, the device is also equipped with a spraying mechanism 4. The spraying mechanism 4 includes a liquid storage tank 41 installed on the top of the support frame 2, and a liquid outlet pipe 42 is installed on the liquid outlet interface of the liquid storage tank 41. A nozzle 43 is installed at the bottom of the liquid outlet pipe 42, and an electric sealing valve 44 is installed on the liquid outlet pipe 42. During grinding, the electric sealing valve 44 is activated, and under the action of gravity, the grinding fluid in the liquid storage tank 41 flows out through the liquid outlet pipe 42 and drips onto the surface of the steel ball through the nozzle 43, thereby improving the grinding effect.

[0037] The storage tank 41 is equipped with an observation window 45 made of transparent tempered glass on its side, and a replenishment pipe 46 is installed on the top of the storage tank 41. The remaining amount of grinding fluid in the storage tank 41 can be observed in real time through the observation window 45, which facilitates timely replenishment of the storage tank 41 through the replenishment pipe 46.

[0038] Example 2

[0039] Based on Example 1, such as Figures 1-5As shown, the electric lifting rod 391 pushes the arc-shaped block 393 downward to press and fix the steel ball. However, the worker needs to control the downward height of the electric lifting rod 391 by feel, which may result in the pressing being too tight or too loose. Therefore, the device is also equipped with a stop component 310. The stop component 310 includes a compression spring 3101 installed on the top wall of the slot opened on the free end of the electric lifting rod 391, and a slide rod 3102 that slides up and down in the slot is installed at the bottom of the compression spring 3101. Connected to the arc-shaped block 393, the top of the slide rod 3102 and the top wall of the slot are both equipped with electrical contacts 3103. When the electric lifting rod 391 moves down, it pushes the arc-shaped block 393 at the bottom of the slide rod 3102 to contact the surface of the steel ball. At this time, the slide rod 3102 is forced to slide up along the inner wall of the slot and squeezes the compression spring 3101 until the electrical contact 3103 at the top of the slide rod 3102 and the electrical contact 3103 at the top of the slot make contact and send an electrical signal. The electric lifting rod 391 is then controlled by the central control panel to stop moving down. No manual operation by the worker is required, making it more stable and efficient.
