Description

Technical Field

[0001] This utility model relates to a fixing fixture, and more particularly to a fixing fixture for a ball mill jar used in the field of chemical equipment. Background Technology

[0002] The grinding jar is one of the core components of a ball mill. It is mainly used to hold grinding materials and grinding media (such as steel balls, ceramic balls, etc.). Through the rotation or vibration of the ball mill, the grinding media and materials collide and rub against each other, thereby realizing the crushing, mixing, grinding and other processes of the materials.

[0003] Chinese Patent CN217368631U discloses a tooling for a twist-lock mechanism in a MLCC ball mill mixing jar, belonging to the technical field of twist-lock mechanisms for MLCC ball mill mixing jars. Technical solution: A handle connected to a main support; a meshing device connected to the main support, having several meshing teeth inside; a knob mounted on a fixed stop bar, meshing with the meshing teeth; a fixing screw, one end connected to the fixed stop bar and the other end connected to the fixing screw base. Beneficial effects: This tooling for a twist-lock mechanism in a MLCC ball mill mixing jar fixes the knob to the jar lid, then places the twist-lock device onto the knob of the lid. The engagement between the twist-lock device and the knob is secured by meshing. Rotating the handle tightens or loosens the jar lid. This tooling saves working time and labor, effectively improving work efficiency.

[0004] In traditional ball mill jar fixing fixtures, the fixing methods are mostly limited to a single direction or a single structure, and can only be adapted to ball mill jars of specific specifications. Such fixtures usually only support the bottom or press the top, which cannot fully cope with the centrifugal force, impact force and vibration generated during the operation of the ball mill. This causes the ball mill jar to easily loosen, shift or even fall off during the operation, which not only affects the grinding effect and production efficiency, but also poses safety hazards. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that in the traditional ball mill jar fixing fixture, the fixing method is mostly limited to a single direction or a single structure, which can only be adapted to ball mill jars of specific specifications. Such fixtures usually only support the bottom or press the top, which cannot fully cope with the centrifugal force, impact force and vibration generated during the operation of the ball mill. As a result, the ball mill jar is prone to loosening, displacement or even falling off during the operation, which not only affects the grinding effect and production efficiency, but also poses safety hazards.

[0006] To address the aforementioned problems, this utility model provides a fixture for fixing a ball mill jar, including a platform. A rotary drive worktable is mounted on the upper end of the platform. Multiple jar support seats are fixedly connected to the upper end of the rotary drive worktable. A jar-holding top frame is fixedly connected to the upper end of each jar support seat. Multiple lateral positioning slots are symmetrically formed on the left and right inner walls of the jar-holding top frame. A limiting transverse fastening plate engages between two corresponding left and right lateral positioning slots. A rotating... A fastening outer ring is provided between the locking pin, the rotating locking pin, and the limiting transverse fastening plate. Several circular hole vertical grooves are opened on the lower inner wall of the tank support. Self-adaptive columns are slidably connected to the inner end of the circular hole vertical grooves. Multiple self-adaptive columns are evenly distributed in the tank support. A wear-resistant top plate is fixedly connected to the upper end of the self-adaptive column. A spring is fixedly connected to the lower end of the self-adaptive column. The spring is fixedly connected to the lower inner wall of the circular hole vertical groove. A wear-resistant top plate is fixedly connected to the upper end of the self-adaptive column. The ball mill tank body is placed in the top frame of the tank.

[0007] In the aforementioned fixture for fixing the ball mill jar, this solution provides stable support through the equipment platform and a multi-dimensional collaborative fixing method, ensuring the stable operation of the ball mill jar under complex working conditions, reducing equipment wear and material spillage caused by unstable fixing, improving the safety and efficiency of ball milling operations, and its flexible adjustment mechanism also reduces the adaptation costs caused by differences in the specifications of the ball mill jar itself.

[0008] As a further improvement of this application, the ball mill jar body is located above multiple wear-resistant top plates, and an elastic buffer pressure ring is fixedly connected to the lower end of the rotating locking pin.

[0009] As a further improvement of this application, a movable limiting ring is sleeved on the outer end of the rotating locking pin, and side crossbars are symmetrically fixedly connected to the left and right ends of the movable limiting ring.

[0010] As another improvement of this application, the upper end of the side crossbar is fixedly connected with multiple retractable outer columns, and the upper end of the retractable outer columns is connected to the lower end of the limiting transverse fastening plate.

[0011] As a further improvement to this application, the inner end of the telescopic outer column is slidably connected to an inner column, and both the telescopic outer column and the inner column have multiple positioning through holes at their front ends.

[0012] As a further improvement to this application, a transverse locking strip is threaded between the two corresponding positioning through holes, and a side guide groove is provided at the inner end of the telescopic outer column.

[0013] As another improvement of this application, the inner end of the inner guide groove is slidably connected to a sliding side block, and the two corresponding sliding side blocks on the left and right are connected to the left and right ends of the inner column.

[0014] In summary, this solution provides stable support through the equipment platform and achieves rotation functionality through a rotary drive worktable, meeting the basic requirements of ball milling operations. The self-adaptive column and spring work together to adaptively adjust according to the bottom position of the ball mill jar, achieving initial fixation and pressure distribution for the bottom of ball mill jars of different diameters, thus improving the versatility of the tooling. The top is secured by rotating the locking column to tighten the outer ring, and the elastic deformation of the elastic buffer ring ensures reliable fixation, preventing vertical loosening. Laterally, the retractable outer column, inner column, and related components work together to adjust and rigidly fix the ball mill jar according to its dimensions, avoiding irregular displacement during rotation. This multi-dimensional and coordinated fixing method ensures stable operation of the ball mill jar under complex working conditions, reducing equipment wear and material spillage caused by unstable fixing, improving the safety and efficiency of ball milling operations. At the same time, its flexible adjustment mechanism also reduces the adaptation costs caused by differences in ball mill jar specifications. Attached Figure Description

Detailed Implementation

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-6 This invention illustrates a fixture for fixing a ball mill jar, including a platform 1. A rotary drive worktable 2 is mounted on the upper end of the platform 1. Multiple jar support seats 3 are fixedly connected to the upper end of the rotary drive worktable 2. A jar-holding top frame 4 is fixedly connected to the upper end of each jar support seat 3. Multiple lateral positioning slots 5 are symmetrically formed on the left and right inner walls of the jar-holding top frame 4. A limiting transverse fastening plate 6 engages between two corresponding left and right lateral positioning slots 5. A rotary locking pin 7 is rotatably connected to the middle of the limiting transverse fastening plate 6. The rotary locking pin 7 and the limiting transverse fastening plate 6 are connected in series. A fastening outer ring 8 is provided between the plates 6. Several circular hole vertical grooves 11 are opened on the lower inner wall of the tank support 3. A self-adaptive column 10 is slidably connected to the inner end of the circular hole vertical groove 11. Multiple self-adaptive columns 10 are evenly distributed in the tank support 3. A wear-resistant top plate 13 is fixedly connected to the upper end of the self-adaptive column 10. A spring 12 is fixedly connected to the lower end of the self-adaptive column 10. The spring 12 is fixedly connected to the lower inner wall of the circular hole vertical groove 11. A wear-resistant top plate 13 is fixedly connected to the upper end of the self-adaptive column 10. The ball mill tank body 21 is placed in the top frame 4 of the tank.

[0027] Figures 2-7 The ball mill jar body 21 is shown above multiple wear-resistant top plates 13. The lower end of the rotating locking pin 7 is fixedly connected to an elastic buffer pressure ring 9. The outer end of the rotating locking pin 7 is fitted with a movable limiting ring 14. The left and right ends of the movable limiting ring 14 are symmetrically fixedly connected to side crossbars 15. The upper end of the side crossbars 15 is fixedly connected to multiple retractable outer pins 16. The upper end of the retractable outer pin 16 and the lower end of the limiting transverse fastening plate 6 are connected to each other. The inner end of the retractable outer pin 16 is slidably connected to an inner pin. Multiple positioning through holes 20 are opened at the front ends of both the retractable outer pin 16 and the inner pin. A transverse locking strip 17 is threaded between two corresponding inner and outer positioning through holes 20.

[0028] Figures 2-7This diagram illustrates a fixture for securing a grinding jar. The equipment platform 1 provides stable support for the entire assembly. A rotary drive table 2, via an external driver, rotates its components. When placing the grinding jar body 21, the operator positions it within the top frame 4. At this time, the self-adaptive columns 10, located in the circular grooves 11 on the lower inner wall of the jar support 3, function. Springs 12 connected to the lower ends of the self-adaptive columns 10 are either compressed or extended. Depending on the actual position of the bottom of the grinding jar body 21, the self-adaptive columns 10 are positioned within the circular grooves 11. The upper wear-resistant top plate 13 slides up and down until it finally comes into close contact with the bottom of the grinding jar body 21 and provides support. This design can be adapted to grinding jar bodies 21 of different diameters, completing the initial fixation of the bottom of the grinding jar and dispersing the downward pressure generated by the grinding jar body 21 during operation. After the initial fixation of the bottom is completed, the top and lateral fixation operations need to be performed. The limiting lateral fastening plate 6 is pre-locked in the lateral positioning slots 5 on the left and right inner walls of the top frame 4 of the jar. By rotating the rotating locking pin 7, the fastening outer ring 8 is driven to rotate together. Since the lower end of the rotating locking pin 7 is fixed The elastic buffer ring 9 of the fixed connection contacts the top surface of the grinding jar body 21. As the outer ring 8 of the fastening ring rotates, the elastic buffer ring 9 gradually presses the top of the grinding jar body 21. Utilizing the friction and pressure generated by the elastic deformation of the rubber, the top of the grinding jar is firmly fixed, preventing the grinding jar body 21 from loosening in the vertical direction. For auxiliary fixing, the movable limiting ring 14 is connected to the retractable outer column 16 through the side crossbar 15. The inner column inside the retractable outer column 16 can slide in the side inner guide groove 18. The sliding side block 19 assists in connecting the inner column and the retractable outer column. The function of 16 is to ensure the stability and guidance of the inner column during the sliding process. According to the actual size of the ball mill jar body 21, the operator passes the transverse locking strip 17 through the corresponding positioning through hole 20 on the telescopic outer column 16 and the inner column, and tightens or loosens it through the threaded connection to adjust the telescopic length of the telescopic outer column 16. After adjusting to the appropriate position, tighten the transverse locking strip 17, and the telescopic outer column 16 and the inner column form a rigid connection, clamping and fixing the ball mill jar body 21 in the transverse direction to prevent irregular displacement of the ball mill jar body 21 during rotation.

[0029] Second implementation method:

[0030] Figure 7A fixture for fixing a ball mill jar is shown. The inner end of the telescopic outer column 16 is provided with a side inner guide groove 18. The inner end of the side inner guide groove 18 is slidably connected to a sliding side block 19. The two corresponding sliding side blocks 19 are connected to the left and right ends of the inner column. The side inner guide groove 18 provides precise guidance for the telescopic movement of the inner column, avoiding the inner column from shifting or getting stuck during the telescopic process, and ensuring the smoothness of the adjustment process. At the same time, when the transverse locking strip 17 is tightened and fixed, the telescopic outer column 16 and the inner column form a rigid connection. Combined with the stabilizing effect of the sliding side block 19, it provides a firm support for the ball mill jar body 21 in the transverse direction, preventing the ball mill jar body 21 from lateral displacement when rotating, ensuring the stable operation of the ball mill jar body 21 under complex working conditions, and improving the safety and processing accuracy of the ball milling operation.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
