Description

Technical Field

[0001] This utility model relates to the field of ceramic trimming machine technology, and in particular to a trimming machine for ceramic processing. Background Technology

[0002] The main purpose of ceramic trimming is to finely trim the formed blank by hand or mechanical means in order to correct shape defects, improve surface smoothness, and facilitate firing. The ceramic trimming machine is a special equipment used to trim the blank (green or semi-dry blank) in the ceramic production process.

[0003] A search of Chinese Patent Publication No. CN222387231U discloses a ceramic trimming device, including a base plate, a trimming mechanism, and a connecting plate mounted on the base plate. The connecting plate is installed on the top left side of the base plate, a fixing plate is installed at the bottom of the connecting plate, a fixing frame is installed at the bottom of the fixing plate, and an mounting plate is installed at the bottom of the fixing frame. The device also drives an anti-splashing mechanism. This invention facilitates the trimming of ceramic products through the cooperation of the connecting plate, fixing plate, fixing frame, mounting plate, annular groove, support rod, support block, rotary motor, placement plate, first electric push rod, moving block, rubber clamping block, fixed shaft, second electric push rod, movable plate, slide groove, third electric push rod, slider, and trimming knife. It also ensures the stability of the ceramic product during trimming, facilitates clamping and limiting of the product during trimming, and guarantees the quality of the trimming process.

[0004] However, in implementing the relevant technology, the above-mentioned trimming device has the following problems. In the prior art, when trimming, the top rubber clamp is pressed against the upper surface of the ceramic blank to hold it. However, since the top of the ceramic blank is generally open, if the rubber clamp is set too small, it will be unable to hold ceramic blanks with large openings. If the rubber clamp is set too large, when processing ceramic blanks with small openings, the excessively large rubber clamp is prone to interfering with the trimming knife. Based on this, this utility model designs a trimming machine for ceramic processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a ceramic processing trimming machine to solve the problem mentioned in the background art that the prior art cannot effectively trim ceramic blanks with different opening sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5The ceramic trimming machine shown includes a fixed base plate 1, on which a rotating shaft 14 is rotatably connected. A drive motor is installed at the bottom of the fixed base plate 1, which drives the rotating shaft 14 to rotate. A support base plate 15 is installed at the top of the rotating shaft 14. Auxiliary support rods are installed on the bottom outer wall of the support base plate 15 to provide auxiliary support. A fixed frame 2 is installed on the top outer wall of the fixed base plate 1, and an electric push rod 3 is installed on the top outer wall of the fixed frame 2. A lifting plate 4 is connected to the output end of the electric push rod 3. A support shaft 5 is rotatably connected to plate 4. A fixed base 6 is installed at the bottom of the support shaft 5. Guide sleeves 7 are installed on all four walls of the fixed base 6. A movable rod 8 is slidably engaged on the guide sleeve 7. Locking blocks 10 are slidably engaged on the guide sleeve 7. An adjusting component 9 for pressing the locking blocks 10 is installed on the side wall of the guide sleeve 7. A fixed block 11 is installed at one end of the movable rod 8. A pressing plate 12 is installed on one side wall of the fixed block 11. Rubber pads are provided at the bottom of the pressing plate 12 and the top of the support base plate 15. Guide plates 13 are installed on all four walls of the fixed base 6. The pressing plate 12 and the... The guide plate 13 is slidably engaged. The adjusting assembly 9 includes a threaded ring 901 located on the side wall of the guide sleeve 7. An adjusting nut 902 is threaded onto the outer surface of the threaded ring 901. A limit ring 903 is installed on one side wall of the adjusting nut 902. By turning the adjusting nut 902, the limit ring 903 is driven to abut against the locking block 10, thereby allowing the locking block 10 to abut against the side wall of the movable rod 8, thus fixing the movable rod 8 to the guide sleeve 7. Furthermore, the side wall of the movable rod 8 is provided with anti-slip patterns, which helps to improve the fixation between the movable rod 8 and the guide sleeve 7. To ensure the stability of the timing, when using this device, first place the ceramic blank on the support base plate 15, then start the electric push rod 3 to drive the lifting plate 4 to press down, so that the four pressing plates 12 can move synchronously to press the upper surface of the ceramic blank. By loosening the adjusting nut 902, the constraint of the limiting pressure ring 903 on the locking block 10 is released, so that the locking block 10 can no longer press the side wall of the movable rod 8. At this time, the movable rod 8 can slide freely in the guide sleeve 7. By adjusting the position of each pressing plate 12 in sequence, it can effectively press ceramic blanks with different opening sizes, thereby improving the applicability of the device.

[0023] In this embodiment, as Figure 1As shown, linear guide rails 16 are installed on the top outer wall of the fixed base plate 1. The linear guide rail 16 is a standard component, a high-precision linear motion guiding device, mainly composed of guide rails, sliders, balls (or rollers), sealing end caps, retainers, and a lubrication system. The linear guide rails 16 are connected to a lifting mechanism 17 via the slider. The lifting mechanism 17 consists of a ball screw and a drive mechanism, etc. A tool base 18 is installed on the lifting mechanism 17, and a dressing tool 19 is engaged on the tool base 18. An electric push rod 22 is installed on the top outer wall of the fixed base plate 1. Both electric push rod 3 and electric push rod 22 are common mechanical devices. A push rod is an electromechanical actuator that converts the rotary motion of an electric motor into linear push-pull motion. It mainly consists of a motor, a reduction mechanism, and a transmission screw. It features controllable stroke, adjustable thrust, and self-locking stability. The output end of the electric push rod 22 is connected to the lifting mechanism 17. After the ceramic blank is fixed, the electric push rod 22 drives the lifting mechanism 17 to move laterally, so that the trimming blade 19 can contact the side wall of the ceramic blank. Then, by driving the support base plate 15 to rotate, the ceramic blank can be rotated, thereby trimming the ceramic blank. Furthermore, the lifting mechanism 17 drives the trimming blade 19 to move up and down, allowing trimming of different positions on the ceramic blank.

[0024] In this embodiment, as Figure 1 As shown, a guide rod 20 is installed on the top outer wall of the lifting plate 4. The guide rod 20 is slidably engaged with the fixed frame 2. The guide rod 20 can guide the lifting plate 4, which helps to improve the stability of the lifting plate 4 when it moves up and down.

[0025] In this embodiment, as Figure 1 As shown, a limiting sleeve 21 is installed on the top outer wall of the fixed frame 2. The limiting sleeve 21 is slidably engaged with the guide rod 20. The limiting sleeve 21 can limit the side wall of the guide rod 20, which helps to ensure the guiding effect of the guide rod 20 on the lifting plate 4.

[0026] The working principle of this utility model is as follows: This utility model is a ceramic blank trimming machine. By placing the ceramic blank on the top of the supporting base plate 15, and then driving the lifting plate 4 to descend through the electric push rod 3, the four pressing plates 12 can simultaneously press against the upper surface of the ceramic blank, thereby fixing the ceramic blank.

[0027] Furthermore, by loosening the adjusting nut 902, the limiting pressure ring 903 no longer abuts against the locking block 10, and the locking block 10 no longer abuts against the side wall of the movable rod 8, thereby allowing the movable rod 8 to slide inside the guide sleeve 7. This allows the position of the pressing plate 12 to be adjusted. By adjusting the position of the pressing plate 12 in sequence, the pressing plate 12 can effectively press the ceramic blanks with different opening sizes, thereby improving the ease of use of the device.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
