Description

Technical Field

[0001] This utility model relates to the field of grinding ball forming technology, and in particular to a centrifugal trimming device for grinding balls. Background Technology

[0002] Grinding balls play a crucial role in numerous industrial sectors. In the mining industry, they are used to crush and grind ores, helping to extract valuable mineral components. In the chemical industry, grinding balls are indispensable for the fine grinding of some solid raw materials, ensuring that the materials reach the appropriate particle size for subsequent chemical reactions.

[0003] If the edges of the grinding balls are irregular, it will lead to uneven energy transfer during the grinding process. This will not only reduce grinding efficiency but may also cause abnormal wear on internal components such as the liners of the ball mill, increasing equipment maintenance costs and downtime. However, traditional mechanical trimming equipment also faces difficulties in positioning and clamping the grinding balls. Since the grinding balls are spherical and prone to rolling, inaccurate positioning during the trimming process can lead to trimming deviations and affect product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a centrifugal trimming device for grinding balls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a centrifugal trimming device for grinding balls, comprising a frame and a support plate, wherein the support plate is fixedly connected to the lower middle part of the frame, and a recessed groove is provided in the upper middle part of the support plate; a lifting mechanism is fixedly installed at the upper end of the frame, and a centrifugal trimming mechanism is fixedly connected to the outer side of the lifting mechanism; the centrifugal trimming mechanism comprises a stepper motor, a connecting plate, a connecting column, a sleeve, side rods, and a ring cutter; the connecting plate is in a horizontal state and is fixedly connected to the lower end of the rotating shaft of the stepper motor; the connecting column is fixedly connected to the lower side of the other end of the connecting plate; the sleeve is fixedly connected to the outer ring surface of the connecting column by bolts; multiple sets of side rods are obliquely fixedly connected to the outer ring surface of the sleeve; and the lower ends of multiple sets of side rods are jointly fixedly connected to a set of ring cutters.

[0006] Preferably, the lifting mechanism includes a guide rail, a slide, a threaded seat, a worm gear, a worm, a connecting rod, a dual-axis motor, a crossbeam, and a lead screw, with the stepper motor fixedly connected to the middle of one side of the crossbeam.

[0007] Preferably, the two sets of threaded seats are fixedly connected to both ends of the crossbeam, and the lead screw is threadedly connected to the middle of the threaded seats.

[0010] Preferably, the connecting rod is drivenly connected to one of the shafts of the dual-axis motor, and the dual-axis motor is fixedly installed on the upper middle part of the upright frame.

[0011] Preferably, the slide is fixedly connected to one side of the threaded seat, the slide is slidably connected to the guide rail, and the guide rail is fixedly connected to the side of the upright.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the prepared grinding ball blank is placed in a recessed groove. The lifting mechanism drives the centrifugal trimming mechanism to descend. During the descent, the grinding ball blank is moved directly below the annular cutter. After ensuring that the annular cutter covers the outside of the grinding ball blank, the dual-axis motor stops working and the stepper motor is started. The rotating shaft of the stepper motor drives the connecting plate to make a circular motion. Through the connecting column, the conical frame composed of the sleeve, side rod and annular cutter makes a circular motion. Under the traction of the annular cutter, the grinding ball blank rolls in the recessed groove. During the rolling process, the annular cutter trims the outer surface of the grinding ball blank. Compared with the traditional trimming equipment for positioning and clamping the grinding ball, the operation is convenient and the trimming quality is improved.

[0014] 2. In this utility model, by controlling the start of the dual-axis motor, its two shafts simultaneously drive the rotation of two sets of connecting rods, which in turn drive the corresponding connected worm gears to rotate. The worm gears mesh with the corresponding worm wheels to rotate, and the two sets of worm wheels simultaneously receive force and drive the connected lead screws to rotate in the threaded seats. Thus, the two sets of threaded seats simultaneously receive a downward component force, causing the slide to slide on the guide rail, thereby realizing the horizontal descent of the crossbeam. The two shafts of the dual-axis motor are connected in a mirror-symmetrical structure, ensuring the stable lifting and lowering of the crossbeam, thereby ensuring the trimming quality of the centrifugal trimming mechanism.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a centrifugal trimming device for grinding balls, including a stand 1 and a support plate 2. The support plate 2 is fixedly connected to the lower middle part of the stand 1. A recessed groove 21 is opened in the upper middle part of the support plate 2. A lifting mechanism 4 is fixedly installed at the upper end of the stand 1. A centrifugal trimming mechanism 3 is fixedly connected to the outside of the lifting mechanism 4. The centrifugal trimming mechanism 3 includes a stepper motor 31, a connecting plate 32, a connecting column 33, a sleeve 34, side rods 35 and a ring cutter 36. The connecting plate 32 is in a horizontal state and is fixedly connected to the lower end of the rotating shaft of the stepper motor 31. The connecting column 33 is fixedly connected to the lower side of the other end of the connecting plate 32. The sleeve 34 is fixedly connected to the outer ring surface of the connecting column 33 by bolts. Multiple sets of side rods 35 are obliquely fixedly connected to the outer ring surface of the sleeve 34. The lower ends of multiple sets of side rods 35 are fixedly connected to a set of ring cutters 36.

[0023] The specific settings and functions of this embodiment are described below: By placing the prepared grinding ball blank in the recessed groove 21, the lifting mechanism 4 drives the centrifugal trimming mechanism 3 to descend. During the descent, the grinding ball blank is moved directly below the annular cutter 36. After ensuring that the annular cutter 36 covers the outside of the grinding ball blank, the dual-axis motor 47 stops working and the stepper motor 31 is started. The rotating shaft of the stepper motor 31 drives the connecting plate 32 to make a circular motion. Through the connecting column 33, the conical frame composed of the sleeve 34, side rod 35 and annular cutter 36 makes a circular motion. Under the traction of the annular cutter 36, the grinding ball blank rolls in the recessed groove 21. During the rolling process, the annular cutter 36 trims the outer surface of the grinding ball blank. Compared with the traditional trimming equipment for positioning and clamping the grinding ball, the operation is convenient and the trimming quality is improved.

[0024] Example 2: Figure 1 - Figure 3 As shown, the lifting mechanism 4 includes a guide rail 41, a slide 42, a threaded seat 43, a worm gear 44, a worm 45, a connecting rod 46, a dual-axis motor 47, a crossbeam 48, and a lead screw 49. The stepper motor 31 is fixedly connected to the middle of one side of the crossbeam 48. Two sets of threaded seats 43 are respectively fixedly connected to both ends of the crossbeam 48. The lead screw 49 is threadedly connected to the middle of the threaded seat 43. The worm gear 44 is fixedly connected to the upper end of the lead screw 49. The upper and lower ends of the lead screw 49 are rotatably connected to the upright 1. The worm 45 is rotatably connected to the upper side of the upright 1. The worm 45 is drive-connected to the connecting rod 46. The connecting rod 46 is drive-connected to one shaft of the dual-axis motor 47. The dual-axis motor 47 is fixedly installed in the middle of the upper side of the upright 1. The slide 42 is fixedly connected to one side of the threaded seat 43. The slide 42 is slidably connected to the guide rail 41. The guide rail 41 is fixedly connected to the side of the upright 1.

[0025] The overall effect of this embodiment is that by controlling the start of the dual-axis motor 47, its two shafts simultaneously drive the two sets of connecting rods 46 to rotate. The connecting rods 46 then drive the corresponding worm gears 45 to rotate. The worm gears 45 mesh with the corresponding worm wheels 44 to rotate. The two sets of worm wheels 44 simultaneously receive force and drive the connected lead screws 49 to rotate in the threaded seats 43. As a result, the two sets of threaded seats 43 simultaneously receive a downward component force, causing the slide 42 to slide on the guide rail 41, thereby realizing the horizontal descent of the crossbeam 48. The two shafts of the dual-axis motor 47 are connected in a mirror-symmetrical structure, ensuring the stable lifting and lowering of the crossbeam 48, thus ensuring the trimming quality of the centrifugal trimming mechanism 3.

[0026] The operating method and working principle of this device are as follows: The prepared grinding ball blank is placed in the recessed groove 21. The dual-axis motor 47 is started, and its two shafts simultaneously drive two sets of connecting rods 46 to rotate. The connecting rods 46 then drive the corresponding worm gears 45 to rotate. The worm gears 45 mesh with the corresponding worm wheels 44, causing them to rotate. Both sets of worm wheels 44 simultaneously receive force and drive the connected lead screw 49 to rotate in the threaded seat 43. Thus, both sets of threaded seats 43 simultaneously receive a downward force, causing the slide 42 to slide on the guide rail 41, achieving a horizontal descent of the crossbeam 48, thereby driving the centrifugal trimming mechanism 3. As the height decreases, the grinding ball blank is moved directly below the annular cutter 36. After ensuring that the annular cutter 36 covers the outside of the grinding ball blank, the dual-axis motor 47 stops working and the stepper motor 31 is started. The rotating shaft of the stepper motor 31 drives the connecting plate 32 to make a circular motion. Through the connecting column 33, the conical frame composed of the sleeve 34, side rod 35 and annular cutter 36 makes a circular motion. Under the traction of the annular cutter 36, the grinding ball blank rolls in the recessed groove 21. During the rolling process, the annular cutter 36 trims the outer surface of the grinding ball blank.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
