Description

Technical Field

[0001] This utility model relates to a multi-station synchronous positioning device for processing ceramic grinding barrels, belonging to the technical field of processing positioning devices. Background Technology

[0002] Ceramic grinding barrels are ceramic products used for grinding and dispersing materials, primarily in grinding equipment such as sand mills, and are widely used in the food, pharmaceutical, and chemical industries. After the ceramic grinding barrels are formed and dried, their upper and lower end faces need to be machined to meet usage requirements. Existing grinding barrel clamping and positioning devices can only clamp one ceramic grinding barrel at a time. After processing, it is removed, and then another one is clamped for processing, resulting in long clamping times and low processing efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a multi-station synchronous positioning device for ceramic grinding barrel processing, which can simultaneously perform synchronous automatic positioning and clamping of multiple ceramic grinding barrels, shorten the clamping time, and thus improve the processing efficiency.

[0004] The multi-station synchronous positioning device for ceramic grinding barrel processing described in this utility model includes a mounting base plate, on which an external toothed rotary bearing is mounted. Several positioning support discs are also evenly distributed on the mounting base plate, and the positioning support discs are fixedly connected to the mounting base plate. A rotating seat is mounted directly below the center of each positioning support disc, and the rotating seat is rotatably connected to the mounting base plate. Several sliding positioning pins are evenly slidably arranged on the rotating seat, penetrating the positioning support discs and confined within limiting grooves on the positioning support discs. The rotating seat is connected to a drive motor via the external toothed rotary bearing.

[0005] The technical solution of this utility model is to provide a multi-station synchronous positioning device for processing ceramic grinding barrels. The device drives the outer gear ring of the external gear slewing bearing to rotate through a drive motor, which in turn drives the rotating seat to rotate. Under the combined action of the rotating seat and the positioning support plate limiting groove, the sliding positioning column moves synchronously, thereby clamping and positioning the ceramic grinding barrel.

[0006] Preferably, the external gear slewing bearing is provided with an external gear ring and an inner seat ring, the external gear ring and the inner seat ring are rotatably connected, and the inner seat ring is fixed to the mounting base plate.

[0007] Preferably, the mounting base plate is provided with a plurality of support columns evenly distributed, and the rotating seat is rotatably connected to the mounting base plate through the support columns.

[0008] Furthermore, a transmission gear is fixed at the bottom of the rotating seat, and the transmission gear meshes with the outer gear ring of the external gear slewing bearing; several guide rods are evenly distributed on the side wall of the rotating seat, and the sliding positioning column is slidably connected to the rotating seat through the guide rods.

[0009] Preferably, a positioning roller is rotatably mounted on the upper part of the sliding positioning column, and the outer wall of the positioning roller is made of hard rubber to prevent scratching the ceramic grinding barrel.

[0010] Preferably, the positioning support plate has an arc-shaped limiting groove.

[0011] The advantages of this utility model compared with the prior art are:

[0012] The multi-station synchronous positioning device for ceramic grinding barrel processing described in this utility model drives the external gear ring of the external gear slewing bearing to rotate via a drive motor, which in turn drives the rotating seat to rotate. Under the combined action of the rotating seat and the positioning support plate limiting groove, the sliding positioning column moves synchronously to clamp and position the ceramic grinding barrel. This utility model can simultaneously perform synchronous automatic positioning and clamping of multiple ceramic grinding barrels, thereby shortening the workpiece clamping time and improving processing efficiency.

[0020] like Figure 1-6As shown, this embodiment is achieved through the following technical solution: it includes a mounting base plate 3, on which an external toothed slewing bearing 4 is mounted, and three sets of positioning support plates 1 are evenly distributed on the mounting base plate 3. The positioning support plates 1 are fixedly connected to the mounting base plate 3. A rotating seat 7 is installed directly below the center of each positioning support plate 1. The rotating seat 7 is rotatably connected to the mounting base plate 3. Three sliding positioning columns 5 are evenly slidably arranged on the rotating seat 7. The sliding positioning columns 5 penetrate the positioning support plate 1 and are limited in the limiting groove 11 on the positioning support plate. The rotating seat 7 is connected to the drive motor 2 through the external toothed slewing bearing 4.

[0021] In this embodiment, the external gear slewing bearing 4 is provided with an external gear ring and an inner seat ring, which are rotatably connected. The inner seat ring is fixed to the mounting base plate 3. Three support columns 31 are evenly provided on the mounting base plate 3, and the rotating seat 7 is rotatably connected to the mounting base plate 3 through the support columns 31. A transmission gear 72 is fixed at the bottom of the rotating seat 7, and the transmission gear 72 meshes with the external gear ring of the external gear slewing bearing 4. Three guide rods 71 ​​are evenly distributed on the side wall of the rotating seat 7, and the sliding positioning column 5 is slidably connected to the rotating seat 7 through the guide rods 71. A positioning roller 51 is rotatably provided on the upper part of the sliding positioning column 5. The outer wall of the positioning roller 51 is made of hard rubber to prevent scratching the ceramic grinding barrel 6. The limiting groove 11 of the positioning support plate 1 is arc-shaped.

[0022] The method of using this utility model is as follows:

[0023] The three ceramic grinding barrels 6 are placed on the respective positioning support plates 1. The drive motor 2 is activated, which drives the outer gear ring of the external gear slewing bearing 4 to rotate, thereby driving the rotating seat 7 to rotate, thus causing the guide rod 71 to rotate. Each sliding positioning pin 5 slides on the guide rod 71 and moves synchronously along the limiting groove 11 toward the center of the positioning support plate 1, thereby clamping and positioning the three ceramic grinding barrels synchronously.
