Description

Technical Field

[0001] This invention relates to the field of positioning technology, specifically to a positioning mechanism for a ceramic brush processing lathe. Background Technology

[0002] A ceramic brush wheel is an industrial tool commonly used for surface treatment, cleaning, and polishing. It mainly consists of a ceramic brush roller and bristles. During production, the ceramic brush roller is mounted on a lathe using a positioning mechanism, and then machined on the lathe.

[0003] A search revealed a Chinese patent application, CN219379796U, which discloses a positioning mechanism for a ceramic brush processing lathe, relating to the field of positioning technology. The mechanism includes a worktable with an adjustable positioning mechanism on its top. This utility model describes a positioning mechanism for a ceramic brush processing lathe. A drive motor drives a worm gear, causing a lifting worm to move a positioning clamping mechanism up and down for height adjustment. Both the front and rear sides of the drive motor are in contact with the front and rear sides of the vertical plate. The top of the vertical plate is threadedly connected to a reinforcing plate using locking bolts. The limiting arc surfaces on the front and rear sides of the reinforcing plate provide limiting protection to the outer wall of the lifting worm. A driven gear drives a telescopic screw to extend and retract left and right to position and clamp ceramic brushes of different sizes, facilitating adjustment and use of the positioning clamping plate. A limiting ring is threadedly connected to the positioning clamping plate via a guide rod, using a limiting groove to position and clamp the ceramic brush, achieving the effect of easy adjustment and positioning for ceramic brush processing.

[0004] However, in the aforementioned patent application, after the ceramic brush roller is fixed by the positioning clamping plate, the position of the ceramic brush roller is fixed. At this time, the lathe can only process the upper surface of the ceramic brush roller, that is, it cannot process the entire ceramic brush roller. If the lower surface of the ceramic brush roller is to be processed, it is necessary to reposition and install it, which increases the number of operation steps and leads to low processing efficiency. Therefore, the present invention provides a positioning mechanism for a ceramic brush wheel processing lathe. Summary of the Invention

[0005] The technical problem solved by this invention is: In the prior art, after the ceramic brush roller is fixed by the positioning clamping plate, the position of the ceramic brush roller is fixed. At this time, the lathe can only process the upper surface of the ceramic brush roller, that is, it cannot process the entire ceramic brush roller. If the lower surface of the ceramic brush roller is to be processed, it is necessary to reposition and install it, which increases the number of operation steps and leads to low processing efficiency.

[0006] This invention can be achieved through the following technical solution: a positioning mechanism for a ceramic wheel brush processing lathe, comprising a rectangular shell with an open top, a rod rotatably disposed through the left side of the rectangular shell, a circular block fixedly connected to one end of the rod inside the rectangular shell, a clamping member disposed on the side of the circular block away from the rod, the clamping member comprising an arcuate support plate fixedly connected to the side wall of the circular block and an arcuate clamping plate slidably disposed on the side wall of the circular block, wherein the arc length of the arcuate support plate is greater than the arc length of the arcuate clamping plate; and multiple threaded push rods are rotatably disposed through the arcuate support plate and the arcuate clamping plate.

[0007] A further technical improvement of the present invention is that: a vertical groove is provided on the side of the circular block away from the first rod, a slider is slidably arranged in the groove, and the arc-shaped clamp is fixed to one side of the slider; a lead screw is rotatably arranged in the groove along the length of the groove, the lead screw passes through the slider, and one end of the lead screw is located outside the circular block.

[0008] A further technical improvement of the present invention is that: a through hole is provided on the right side of the rectangular shell, and a second rod is inserted through the through hole, which moves and rotates horizontally within the through hole; a limit plate is fixed to one end of the second rod outside the rectangular shell, and a circular block is fixed to the other end; a clamping member is also provided on the side of the circular block away from the second rod.

[0009] A further technical improvement of the present invention is that: a mounting groove is provided on the front side of the rectangular shell, a rotating shaft is rotatably provided at the bottom of the mounting groove, and a stop is fixedly connected to the rotating shaft; the rotating shaft is driven by a worm gear mechanism.

[0010] A further technical improvement of the present invention is that: the worm gear mechanism includes a worm wheel sleeved and fixed to one end of the rotating shaft, and a mounting shell is also fixed to the outer wall of the rectangular housing. The worm wheel is located inside the mounting shell, and a worm is rotatably connected inside the mounting shell. The worm and the worm wheel are in a meshing state.

[0011] A further technical improvement of the present invention is that: a base is provided below the rectangular shell, and guide rods are fixedly connected to all four sides of the bottom of the rectangular shell. The bottom end of the guide rod passes through and is slidably disposed on the base. An electric cylinder is provided below the base, and a push rod is fixedly connected to the output shaft of the electric cylinder. The top end of the push rod passes through the base and is fixedly connected to the bottom of the rectangular shell.

[0012] A further technical improvement of the present invention is that: slots are provided at equal intervals on the outer side wall of the guide rod, and the bottom of the slots is inclined upward; insert plates are slidably connected through both the left and right sides of the base, and an insert block is fixedly connected to one side of the insert plate inside the base, and the bottom of the insert block is also inclined upward.

[0013] A further technical improvement of the present invention is that: a push plate is fixedly connected to one end of the insert plate outside the base, and a spring is fixedly connected between the push plate and the base; when the insert block is inserted into the slot, the spring is in its original length state.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this invention, the ceramic brush roller is positioned by clamping it between the arc support plate and the arc clamping plate. When processing the ceramic brush roller, the first rod is rotated by the motor, so that both the upper and lower surfaces of the ceramic brush roller can be processed without repositioning, which helps to improve processing efficiency.

[0016] 2. In this invention, when clamping ceramic brush rollers of different diameters, there will be a problem of small contact area between the ceramic brush roller and the arc support plate and the arc clamping plate. At this time, by rotating the threaded push rod, one end of the threaded push rod is made to abut against the surface of the ceramic brush roller, thereby increasing the contact area with the ceramic brush roller and improving the clamping stability.

[0017] 3. In this invention, the rectangular shell has the function of collecting debris, and the side wall of the rectangular shell has the function of blocking debris, so that the debris generated during processing will not splash outside the rectangular shell, reducing the injury of the splashed debris to the operator.

[0018] 4. In this invention, since the bottoms of the slot and the plug are both angled upwards, it is convenient for the guide rod to move upwards under the drive of the electric cylinder. Since the tops of the slot and the plug are both horizontal, the plug will restrict the guide rod from moving downwards. At this time, the electric cylinder can stop working, and the rectangular housing can also remain in place, thereby reducing the force on the electric cylinder and increasing the service life of the electric cylinder.

Detailed Implementation

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figures 1-6 As shown, a positioning mechanism for a ceramic brush processing lathe includes a rectangular housing 1 with an open top. A rod 2 is rotatably mounted through the left side of the rectangular housing 1, and the rod 2 is located at the center of the left side of the rectangular housing 1, or slightly below the center. The rod 2 is driven by a motor, which is fixedly mounted on the outer left side wall of the rectangular housing 1. A circular block 3 is fixedly connected to one end of the rod 2 inside the rectangular housing 1. A clamping component is provided on the side of the circular block 3 away from the rod 2. The clamping component includes an arc-shaped support plate 5 fixed to the side wall of the circular block 3 and an arc-shaped clamping component slidably mounted on the side wall of the circular block 3. Plate 4, and the arc length of the arc support plate 5 is greater than the arc length of the arc clamping plate 4; when clamping the ceramic brush roller, first make the arc support plate 5 below the arc clamping plate 4, then place the ceramic brush roller above the arc support plate 5, and then move the arc clamping plate 4 downward so that the ceramic brush roller is clamped between the arc support plate 5 and the arc clamping plate 4, thereby achieving the positioning of the ceramic brush roller. When processing the ceramic brush roller, the motor drives the first rod 2 to rotate so that both the upper and lower surfaces of the ceramic brush roller can be processed without repositioning, which is beneficial to improving processing efficiency;

[0029] The arc length of the arc support plate 5 is greater than that of the arc length of the arc clamping plate 4, so that ceramic brush rollers of different diameters can be positioned on the side wall of the circular block 3 first, and then fixed with the arc clamping plate 4.

[0030] In the above, multiple threaded push rods 6 are rotatably mounted through the arc support plate 5 and the arc clamping plate 4. When clamping ceramic brush rollers of different diameters, the contact area between the ceramic brush roller and the arc support plate 5 and the arc clamping plate 4 becomes small. At this time, by rotating the threaded push rod 6, one end of the threaded push rod 6 abuts against the surface of the ceramic brush roller, thereby increasing the contact area with the ceramic brush roller and improving the stability of clamping. In order to reduce damage to the surface of the ceramic brush roller, a rubber layer is also provided at the end of the threaded push rod 6.

[0031] In the above description, the driving structure of the arc clamping plate 4 can be as follows: a vertical groove 20 is provided on the side of the circular block 3 away from the first rod 2, and a slider 21 is slidably arranged in the groove 20. The arc clamping plate 4 is fixed to one side of the slider 21. A lead screw 7 is rotatably arranged in the groove 20 along the length of the groove 20. The lead screw 7 passes through the slider 21, and one end of the lead screw 7 is located outside the circular block 3. When the ceramic brush roller is placed on the top of the arc support plate 5, the lead screw 7 is rotated to drive the slider 21 to move downward. The slider 21 then slides downward along the groove 20, causing the arc clamping plate 4 to move downward, thereby clamping the ceramic brush roller.

[0032] To improve the stability of the ceramic brush roller during processing, a through hole is provided on the right side of the rectangular housing 1, through which a second rod 8 is inserted. The second rod 8 moves horizontally and rotates within the through hole. A limit plate is fixed to one end of the second rod 8 outside the rectangular housing 1, and a circular block 3 is fixed to the other end. A clamping component is also provided on the side of the circular block 3 away from the second rod 8. When positioning the ceramic brush roller, the second rod 8 is pushed first, so that the distance between the circular block 3 on the second rod 8 and the circular block 3 on the first rod 2 is sufficient to accommodate the ceramic brush roller. When one end of the ceramic brush roller is fixed to the circular block 3 on the first rod 2, the second rod 8 is pushed again, causing the second rod 8 to move the circular block 3 toward the ceramic brush roller. Then, the clamping component is used to clamp the other end of the ceramic brush roller, thus improving the stability of the ceramic brush roller during processing.

[0033] In this application, the rectangular shell 1 has the function of collecting debris, and the side wall of the rectangular shell 1 has the function of blocking debris, so that the debris generated during processing will not splash to the outside of the rectangular shell 1, reducing the injury of the splashed debris to the operator.

[0034] Furthermore, to facilitate the cleaning of debris, a mounting groove is provided on the front side of the rectangular housing 1. A rotating shaft 9 is rotatably mounted at the bottom of the mounting groove, and a stop gate 10 is fixedly connected to the rotating shaft 9. The rotating shaft 9 is driven by a worm gear mechanism. The worm gear mechanism includes a worm wheel sleeved and fixedly connected to one end of the rotating shaft 9. A mounting shell 11 is also fixedly connected to the outer wall of the rectangular housing 1. The worm wheel is located inside the mounting shell 11, and a worm is rotatably connected inside the mounting shell 11. The worm and the worm wheel are in a meshing state. When cleaning debris inside the rectangular housing 1, the worm is rotated, causing the worm to drive the worm wheel to rotate. The worm wheel then drives the rotating shaft 9 and the stop gate 10 to rotate, so that the front side of the rectangular housing 1 is in an open state, which facilitates the cleaning of debris from inside the rectangular housing 1.

[0035] To facilitate adjustment of the processing position height, a base 13 is provided below the rectangular housing 1. Guide rods 12 are fixedly connected to all four sides of the bottom of the rectangular housing 1. The bottom end of the guide rod 12 passes through and slides on the base 13. An electric cylinder is provided below the base 13. A push rod 14 is fixedly connected to the output shaft of the electric cylinder. The top end of the push rod 14 passes through the base 13 and is fixedly connected to the bottom of the rectangular housing 1. During operation, the electric cylinder is activated, causing the electric cylinder to drive the rectangular housing 1 to move up and down, thereby changing the overall height of the ceramic brush roller, which facilitates the machining of the ceramic brush roller by the lathe tool.

[0036] When the rectangular housing 1 moves to a designated height, in order to reduce the force on the electric cylinder and increase its service life, slots 15 are provided at equal intervals on the outer side wall of the guide rod 12, and the bottom of the slots 15 is inclined upwards; the left and right sides of the base 13 are connected by insert plates 16 through and slidingly connected, and the insert plate 16 is fixedly connected to the side of the insert plate 16 inside the base 13 with a plug block 17, and the bottom of the plug block 17 is also inclined upwards; the end of the insert plate 16 outside the base 13 is fixedly connected to a push plate 18, and a spring 19 is fixedly connected between the push plate 18 and the base 13. When the plug block 17 is inserted into the slot 15, the spring 19 is in its original length state; during operation, when the electric cylinder When the rectangular housing 1 moves upward, the guide rod 12 will move upward. At this time, the insertion block 17 slides with the slot 15, causing the insertion block 17 to move the insertion plate 16 away from the guide rod 12. At this time, the spring 19 is stretched. When the guide rod 12 moves to the specified height, the elastic force of the spring 19 will cause the insertion plate 16 to move closer to the guide rod 12, thereby causing the insertion block 17 to be inserted into the slot 15. Since the tops of the slot 15 and the insertion block 17 are both horizontal, the insertion block 17 will restrict the guide rod 12 from moving downward. At this time, the electric cylinder can stop working, and the rectangular housing 1 can also remain in its position.

[0037] In use, when positioning the ceramic brush roller, the second rod 8 is first pushed so that the distance between the circular block 3 on the second rod 8 and the circular block 3 on the first rod 2 is sufficient to accommodate the ceramic brush roller. After one end of the ceramic brush roller is placed on the top of the arc support plate 5 on the circular block 3 of the first rod 2, the lead screw 7 is rotated, causing the lead screw 7 to drive the slider 21 downward. The slider 21 then slides downward along the slide groove 20, causing the slider 21 to drive the arc clamping plate 4 downward, thus clamping the ceramic brush roller. The ceramic brush roller is clamped between the arc support plate 5 and the arc clamping plate 4, achieving the positioning of the ceramic brush roller. The second rod 8 is pushed again, causing the second rod 8 to drive the circular block 3 to move closer to the ceramic brush roller. Then, the clamping device is used to clamp the other end of the ceramic brush roller, which can improve the stability of the ceramic brush roller during processing. By rotating the threaded top rod 6, one end of the threaded top rod 6 abuts against the surface of the ceramic brush roller, thereby increasing the contact area with the ceramic brush roller and improving the clamping stability.

[0038] The electric cylinder is activated, causing the rectangular housing 1 to move up and down, thus changing the overall height of the ceramic brush roller and facilitating the machining of the ceramic brush roller by the lathe tool. When the electric cylinder moves the rectangular housing 1 upward, the guide rod 12 moves upward. At this time, the insert block 17 slides with the slot 15, causing the insert block 17 to move the insert plate 16 away from the guide rod 12. At this time, the spring 19 is stretched. When the guide rod 12 moves to the specified height, the elastic force of the spring 19 will move the insert plate 16 closer to the guide rod 12, thus causing the insert block 17 to be inserted into the slot 15. Since the tops of the slot 15 and the insert block 17 are both horizontal, the insert block 17 will restrict the downward movement of the guide rod 12. At this time, the electric cylinder can stop working, and the rectangular housing 1 can also remain in its current position.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
