Sphere sorting machine

Abstract

When balls are sorted, balls to be screened can be placed in a feeding area of a sorting groove of a sorting frame in batches, due to the fact that the bottom wall of the sorting groove inclines downwards in the length direction, the balls can roll in the length direction of the bottom wall of the sorting groove under the action of gravity, and the rolling track of the balls with insufficient roundness is nonlinear. The balls can deviate in the horizontal direction and finally collide with the groove walls on the two sides of the sorting groove in the width direction, so that the balls with insufficient roundness are retained near the waste stopping surface; the balls with enough roundness are approximately linear in rolling track and cannot deviate in the horizontal direction, so that the balls can be kept rolling in the length direction of the bottom wall, finally, the balls with enough roundness flow out of the sorting frame from the discharging port, and good balls with enough roundness are screened and selected. According to the ball sorting machine, the balls can be placed in batches for screening, so that the efficiency of screening and selecting the balls can be improved, and the roundness error of the sorted balls is small.

Description

Technical Field

[0001] This utility model relates to the production of spheres, and in particular to a sphere sorting machine. Background Technology

[0002] Spherical parts are widely used in mechanical equipment, primarily to reduce frictional resistance and improve motion accuracy. During the production of spherical parts, such as steel balls, roundness needs to be screened to distinguish between well-rounded (good) balls and poorly rounded (incomplete) balls. Some existing ball sorting machines use two side-by-side screen rollers, inclined along their length and rotating. The balls to be sorted are placed one by one between the two rollers. Balls with insufficient roundness fall through the gap between the rollers, while well-rounded balls flow out along the length of the rollers, resulting in good-rounded balls. However, this type of ball sorting machine requires the balls to pass through the rollers one by one, resulting in relatively low efficiency in ball selection. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sphere sorting machine that can improve the efficiency of screening and selecting spheres.

[0004] A sphere sorting machine according to an embodiment of the present invention includes a base and a sorting frame. The sorting frame is disposed on the base and has a sorting trough extending in a straight line. The bottom wall of the sorting trough is inclined downward along its length direction, and the width direction of the bottom wall of the sorting trough is horizontal. A feeding area is provided at one end of the sorting trough along its length direction, and the feeding area is located at the upper end of the bottom wall. A discharge port is provided at the other end of the sorting trough along its length direction, and the discharge port is located at the lower end of the bottom wall. The two side walls of the sorting trough form waste stop surfaces.

[0005] The ball sorting machine according to the present invention has at least the following beneficial effects: When sorting balls, the balls to be screened can be placed in batches into the feeding area of ​​the sorting trough of the sorting frame. Since the bottom wall of the sorting trough is inclined downwards along its length, under the action of gravity, the balls will roll along the length of the bottom wall of the sorting trough. The rolling trajectory of balls with insufficient roundness is non-linear, and they will deviate horizontally, eventually colliding with the two sides of the trough wall in the width direction, causing the balls with insufficient roundness to remain near the waste stop surface; the rolling trajectory of balls with sufficient roundness is approximately linear, and they will not deviate horizontally, thus maintaining rolling along the length of the bottom wall, and finally allowing the balls with sufficient roundness to flow out of the sorting frame from the discharge port, thereby screening and selecting good balls with sufficient roundness. The above-mentioned ball sorting machine can put balls in batches for screening, thereby improving the efficiency of screening and selecting balls, and the roundness error of the sorted balls is small.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 4 The ball sorting machine of this utility model includes a base 100 and a sorting frame 200. The sorting frame 200 is disposed on the base 100 and has a sorting trough 210 extending in a straight line. The bottom wall 211 of the sorting trough 210 is inclined downward along the length direction and the width direction of the bottom wall 211 is horizontal. A feeding area 220 is provided at one end of the sorting trough 210 along the length direction and is located at the upper end of the bottom wall 211. A discharge port 230 is provided at the other end of the sorting trough 210 along the length direction and is located at the lower end of the bottom wall 211. The two side walls of the sorting trough 210 form waste stop surfaces 212.

[0030] When sorting spheres, the spheres to be screened can be placed in batches into the feeding area 220 of the sorting trough 210 of the sorting frame 200. Since the bottom wall 211 of the sorting trough 210 slopes downwards along its length, under the influence of gravity, the spheres will roll along the length of the bottom wall 211. Spheres with insufficient roundness will have a non-linear rolling trajectory and will deviate horizontally, eventually colliding with the sides of the sorting trough 210 in the width direction, causing them to remain near the waste stop surface 212. Spheres with sufficient roundness will have an approximately straight rolling trajectory and will not deviate horizontally, thus maintaining their rolling along the length of the bottom wall 211. Finally, spheres with sufficient roundness will flow out of the sorting frame 200 from the discharge port 230, thereby selecting and obtaining well-rounded spheres with sufficient roundness. The above-described sphere sorting machine allows for batch loading of spheres for screening, thereby improving the efficiency of sphere selection and resulting in a smaller roundness error in the sorted spheres.

[0031] It should be understood that the bottom wall 211 of the sorting tank 210 is flat, which facilitates the rolling of the balls. Preferably, the feed area 220 and the central axis of the sorting tank 210 are vertically aligned, resulting in a better overall sorting effect.

[0032] In this embodiment, the base 100 includes a main body 110 and a vibrator 120. The sorting frame 200 is mounted on the main body 110, and the vibrator 120 is disposed on the main body 110 and used to vibrate the sorting frame 200. The vibrator 120 provides a vibration effect to the sorting frame 200, allowing the balls to be screened to roll along the length of the bottom wall 211 of the sorting groove 210 at a faster speed. Furthermore, when a batch of balls is placed into the sorting groove 210, the balls can be dispersed more quickly, reducing the risk of the balls obstructing and interfering with each other during rolling.

[0033] Specifically, the vibrator 120 can be a rotary vibrator 120, such as a motor with an eccentric wheel; or an electromagnetic vibrator 120, etc., which can be selected by those skilled in the art according to actual needs. The vibrator 120 is preferably an adjustable frequency and amplitude vibrator 120, which can adjust the vibration frequency and amplitude to adapt to spheres of different diameters.

[0034] In this embodiment, the base 100 further includes elastic support legs 130. A vibrator 120 is connected to the bottom of the main body 110. A ground support surface is provided on the lower side of the vibrator 120, and the elastic support legs 130 are located at the bottom of the main body 110. When the ball sorting machine is in use, the ground support surface on the lower side of the vibrator 120 directly abuts against the ground. The elastic support legs 130 are installed at the bottom of the main body 110, resulting in better overall vibration of the main body 110 and reducing the risk of local vibration attenuation. This eliminates the need for multiple vibrators 120, thus reducing manufacturing costs.

[0035] Specifically, the elastic support leg 130 is a spring, which has a simple structure and is easy to implement. It is conceivable that in other embodiments, the elastic support leg 130 can also be a component with good elasticity, such as a rubber block or a silicone block; those skilled in the art can choose according to actual needs.

[0036] In this embodiment, the vibrator 120 and the elastic support 130 are arranged at intervals in the front-to-back direction, which facilitates the transmission of the vibration effect of the vibrator 120 to various positions of the main body 110, and eliminates the need for an excessive number of elastic support 130, thus saving material costs.

[0037] In this embodiment, an angle adjustment mechanism 300 is also included. The angle adjustment mechanism 300 is disposed between the base 100 and the sorting frame 200. The angle adjustment mechanism 300 is used to adjust the inclination angle of the bottom wall 211 of the sorting trough 210 along its length. Since the diameter of the spheres varies, when sorting spheres with larger diameters, the spheres with larger diameters have greater rolling kinetic energy. Therefore, the inclination angle of the bottom wall 211 of the sorting trough 210 can be reduced to decrease the rolling speed of the spheres and reduce sphere jumping. When sorting spheres with smaller diameters, the spheres with smaller diameters have less rolling kinetic energy. Therefore, the inclination angle of the bottom wall 211 of the sorting trough 210 can be increased to increase the rolling speed of the spheres, thereby improving the sorting efficiency.

[0038] In this embodiment, the angle adjustment mechanism 300 includes two lifting adjustment components 310. The two lifting adjustment components 310 are arranged along the length of the sorting groove 210. Each lifting adjustment component 310 includes a bolt and nut pair, a strip hole 311, and a mounting through hole 312. The strip hole 311 is disposed on the base 100 and extends in the vertical direction. The mounting through hole 312 is disposed on the sorting frame 200. The bolt and nut pair passes through the strip hole 311 and the mounting through hole 312. The bolt and nut pair can slide vertically along the strip hole 311 and is used to lock the sorting frame 200 to the base 100.

[0039] When both bolt and nut pairs of the lifting adjustment components 310 are tightened, the sorting frame 200 is locked and fixed to the base 100. When the bolt and nut pairs of the two lifting adjustment components 310 are loosened, the bolt and nut pairs can be slid up and down along the strip hole 311, thereby adjusting the height of both ends of the bottom wall 211 of the sorting trough 210 along its length, that is, adjusting the tilt angle of the bottom wall 211. The adjustment effect is good and the use is convenient and flexible. The overall height of the sorting frame 200 can also be adjusted slightly.

[0040] It is conceivable that the angle adjustment mechanism 300 can also be other structures, such as including a pin, a first pin hole and a second pin hole. The middle part of the sorting frame 200 is rotatably connected to the base 100. The base 100 is provided with a first pin hole. The sorting frame 200 is provided with a plurality of second pin holes arranged around its rotation axis. The sorting frame 200 can rotate relative to the base 100 to adjust the tilt angle of the sorting groove 210. The pin is inserted into the first pin hole and one of the second pin holes to lock the angle of the sorting groove 210. When the pin is pulled out, the tilt angle of the sorting groove 210 can be adjusted.

[0041] Preferably, the inclination angle of the bottom wall 211 of the sorting trough 210 is A, which satisfies 0°<A≤5°, and each sorting rack 200 corresponds to an angle adjustment mechanism 300.

[0042] In this embodiment, the bottom wall 211 of the sorting trough 210 is positioned horizontally along its width. Three sorting frames 200 are arranged vertically. In two adjacent sorting frames 200, the discharge port 230 of the upper sorting frame 200 and the feed area 220 of the lower sorting frame 200 are vertically opposite each other. The discharge port 230 of one sorting trough 210 is located at its front end, and the discharge port 230 of the other sorting trough 210 is located at its rear end. The aforementioned ball sorting machine has a plurality of sorting frames 200, which are approximately tilted back and forth and stacked vertically. This maintains a sufficiently long overall length of the sorting trough 210 while reducing the footprint of the ball sorting machine, resulting in a more compact structure. Specifically, in two adjacent sorting frames 200, one sorting trough 210 is tilted forward and downward, and the other is tilted backward and downward.

[0043] It is conceivable that in other embodiments, the ball sorting machine may also be provided with two, four or more sorting racks 200, which can be selected by those skilled in the art according to actual needs.

[0044] It is understandable that in some embodiments, the base 100 may be provided with only one sorting rack 200. In this case, the sorting rack 200 needs to be made relatively long so that the length of the sorting groove 210 is long enough to sort the balls well.

[0045] In this embodiment, the width of the sorting slots 210 of each sorting rack 200 gradually increases from top to bottom. In two adjacent sorting racks 200, the discharge port 230 of the upper sorting slot 210 is located within the lower sorting slot 210. This structure, in two adjacent sorting racks 200, facilitates the stable entry of the ball from the upper sorting slot 210 into the feed area 220 of the lower sorting slot 210. Furthermore, the upper sorting rack 200 is partially embedded within the sorting slot 210 of the lower sorting rack 200, which helps to fully utilize the upper space of the sorting slot 210, making the stacked arrangement of multiple sorting racks 200 more compact, and reducing the likelihood of the ball jumping out of the current sorting slot 210.

[0046] Specifically, in this embodiment, the sorting rack 200 is a plate structure, which reduces the material consumption and weight of the sorting rack 200.

[0047] In this embodiment, an air-blowing assembly is also included. This assembly is mounted on the base 100 and used to blow air into the sorting tank 210. After a batch of balls is sorted, some defective balls remain in the sorting tank 210. Therefore, the air-blowing assembly can be used to blow air into the sorting tank 210, driving the defective balls out of the current sorting tank 210 through the discharge port 230, thereby cleaning up the defective balls and facilitating subsequent production processes of the ball sorting machine. Specifically, the air-blowing assembly can use an air compressor in conjunction with an air-blowing pipeline to blow air into the sorting tank 210; or it can directly use a blower to blow air into the sorting tank 210.

[0048] In this embodiment, the sorting rack 200 includes a main frame 240 and a bottom plate 250. The bottom plate 250 is disposed on the main frame 240, and the bottom plate 250 and the main frame 240 enclose a sorting trough 210, with the bottom plate 250 forming the bottom wall 211 of the sorting trough 210. The sorting rack 200 described above can be made of different materials for the main frame 240 and the bottom plate 250, resulting in different coefficients of friction for the bottom wall 211 and side walls of the sorting trough 210, thus improving its performance.

[0049] Specifically, the base plate 250 can be made of glass, which reduces friction on the ball, allowing it to roll smoothly, and the translucent glass makes it easy to observe the distribution of the balls. The main frame 240 can be made of metal, which gives the two ball stop surfaces higher friction on the ball, making it easier to keep defective balls near the ball stop surfaces.

[0050] Optionally, the bottom sorting trough 210 has a tapering structure at the end near the discharge port 230, making the discharge port 230 narrower and easier to collect.

[0051] Optionally, the uppermost sorting trough 210 also has a tapering structure at the end near the feed area 220, so that the poured-in balls can roll stably from near the central axis.

[0052] Specifically, when using the ball sorting machine, the balls to be sorted are poured into the sorting trough 210 from the feeding area 220 of the uppermost sorting frame 200, and the vibrator 120 is started. Balls with sufficient roundness will roll almost in a straight line along the length of the bottom wall 211 of the sorting trough 210, and then enter the feeding area 220 of the lower sorting trough 210 from the discharge port 230. This cycle is repeated, and finally, good balls can be collected at the discharge port 230 of the sorting trough 210 of the lowermost sorting frame 200. Good balls can be collected using a collection box. Balls with insufficient roundness will shift horizontally during the rolling process and eventually come into contact with the waste stop surfaces 212 on both sides, remaining in the sorting trough 210.
