Description

Technical Field

[0001] The invention relates to the technical field of special ceramic materials, in particular to a special ceramic material stress relief device. Background Art

[0002] Due to their unique physical and chemical properties, special ceramics are widely used in many fields, such as aerospace, electronics, and medical treatment. However, during the production and processing of ceramics, various factors often cause stress inside the material, which may affect the performance and service life of the ceramics.

[0003] At present, the vibration method is widely used as an effective means to eliminate stress on the ceramic surface. This method uses the vibration waves generated by the equipment to vibrate the ceramic material, thereby releasing the internal stress of the material.

[0004] Most existing vibration equipment uses electronic control to change the amplitude of vibration. Although this method achieves controllability of vibration to a certain extent, the electronic control system is prone to bugs, which makes the frequency change of vibration difficult to control: excessive vibration amplitude may damage the ceramic material and cause cracks inside, thus affecting its performance and service life, while too small vibration amplitude may lead to incomplete stress elimination and fail to achieve the expected treatment effect.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 4 , the present invention provides a technical solution: a stress relief device for special ceramic materials, comprising a vibration box 1, the inner wall of which is fixedly mounted a vibration frequency adjustable mechanism; The vibration frequency adjustable mechanism includes a fixed plate 2 fixedly installed on the bottom surface of the inner wall of the vibration box 1, a motor 4 is fixedly installed on the side wall of the fixed plate 2, a cam 3 is fixedly installed on the driving end of the motor 4, a connecting rod 6 is rotatably installed on the protrusion of the cam 3, a connecting rod 2 8 and a connecting rod 3 9 are rotatably installed on the end of the connecting rod 6 away from the cam 3, a sliding column 11 is rotatably installed on the end of the connecting rod 2 8 away from the connecting rod 1 6, an arc-shaped slide plate 10 is slidably installed on the side wall of the sliding column 11, a screw 12 is threadedly connected to the inner wall of the sliding column 11, a transverse bevel gear 13 is fixedly installed on the top of the screw 12, a sliding rod 16 is fixedly installed on the end of the connecting rod 3 9 away from the connecting rod 1 6, and a chassis 18 is fixedly installed on the top of the sliding rod 16.

[0024] It should be noted that: the motor 4 drives the cam 3 to rotate, and the protrusion of the cam 3 is rotatably connected to the connecting rod 6. Therefore, as the cam 3 rotates, the connecting rod 6 will reciprocate, and the movement of the connecting rod 6 is transmitted to the sliding rod 16 through the connecting rod 3 9. At the same time, the sliding rod 16 slides on the inner wall of the sleeve 17, which increases the stability and vibration effect of the sliding rod 16. The chassis 18 is fixedly installed on the top of the sliding rod 16, so the chassis 18 will vibrate with the movement of the sliding rod 16, thereby eliminating the stress inside the ceramic material; Furthermore, when the ceramic material begins to eliminate stress, in order to avoid excessive internal stress causing cracks on the surface of the ceramic material, the vibration frequency needs to be reduced. At this time, by adjusting the extended length of the screw 12, the travel of the slide rod 16 becomes longer, thereby reducing the vibration frequency; Furthermore, when most of the stress inside the ceramic material has disappeared, the stroke of the slide rod 16 is shortened by adjusting the extended length of the screw rod 12, thereby increasing the vibration frequency and further reducing the remaining small stress.

[0025] See also Figure 1 , Figure 2 , including a transverse bevel gear 13 whose outer wall is meshed with a vertical bevel gear 21 , a connecting column 23 is fixedly installed on the inner wall of the vertical bevel gear 21 , a rotating handle 14 is fixedly installed on the end of the connecting column 23 , and the rotating handle 14 is rotatably installed on the outer wall of the vibration box 1 .

[0026] It should be noted that: in the initial state, the transverse bevel gear 13 is in meshing state with the vertical bevel gear 21, but the rotating handle 14 is not rotated. At this time, the extended length of the screw rod 12 remains unchanged, and the angle of the connecting rod system and the stroke of the slide rod 16 also remain constant. When it is necessary to adjust the extended length of the screw rod 12, the operator will rotate the rotating handle 14. The rotation of the rotating handle 14 will drive the connecting column 23 and the vertical bevel gear 21 to rotate together, and the rotation of the transverse bevel gear 13 will drive the screw rod 12 to rotate. Since the screw rod 12 and the slide column 11 are threadedly connected, the rotation of the screw rod 12 will change its extended length. As the extended length of the screw rod 12 increases or decreases, the angle of the connecting rod system and the stroke of the slide rod 16 will also change accordingly. When the rotation speed of the motor 4 remains unchanged, the stroke of the slide rod 16 can be changed by adjusting the extended length of the screw rod 12, thereby achieving the adjustment of the vibration frequency. Furthermore, the rotating handle 14 is installed on the outer side wall of the vibration box 1, which is convenient for the operator to make adjustments at any time, thereby improving the convenience and flexibility of operation.

[0027] See also Figure 1 , Figure 2 , including a supporting plate 15 rotatably mounted on the outer wall of a connecting column 23, a sleeve 17 fixedly mounted on the side end of the supporting plate 15, an inner wall of the sleeve 17 is slidably connected to the outer wall of the sliding rod 16, a supporting plate 20 is fixedly mounted on the side wall of the sleeve 17 away from the supporting plate 15, a swinging plate 22 is rotatably mounted on the inner wall of one end of the supporting plate 20 away from the sleeve 17, the inner wall at the bottom of the swinging plate 22 is rotatably connected to the screw rod 12, and the inner wall at the top of the swinging plate 22 is rotatably connected to the connecting column 23.

[0028] It should be noted that when the screw rod 12 is rotated by an external force, the swing plate 22 will swing accordingly due to the rotational connection between the swing plate 22 and the screw rod 12, thereby limiting the screw rod 12 to prevent the screw rod 12 from causing the slide column 11 to deviate from the predetermined position during movement.

[0029] See also Figure 3 , including a limit plate 19 fixedly installed on the top of the chassis 18, a limit groove 24 is arranged on the surface of the limit plate 19, a slider 25 is slidably installed on the inner wall of the limit groove 24, a connecting rod 28 is rotatably installed at the bottom of the slider 25, and a rotating plate 29 is rotatably installed on the end of the connecting rod 28 away from the slider 25.

[0030] It should be noted that when an external force acts on the slider 25, the slider 25 will slide in the limiting groove 24, and the sliding of the slider 25 will drive one end of the connecting rod 4 28 to move, thereby changing the angle between the connecting rod 4 28 and the rotating disk 29; Furthermore, during the entire movement process, the chassis 18 and the limit plate 19 remain unchanged as fixed points, while the slider 25 and the connecting rod 28 move relatively around the rotating plate 29, so that the entire device can flexibly adapt to ceramic materials of different sizes.

[0031] See also Figure 3 , Figure 4 , including a rotating disk 29 whose top is fixedly mounted on the driving end of a second motor 30 , and a top of the second motor 30 is fixedly connected to the center of the bottom of the limiting disk 19 .

[0032] It should be noted that: when the motor 2 30 is started, its driving end will drive the rotating disk 29 to rotate; Furthermore, since the limiting plate 19 is fixedly connected to the top of the motor 2 30, it can provide stable support and limitation for the rotating plate 29 to prevent it from shaking or deflecting during rotation.

[0033] See also Figure 3 , Figure 4 , including slide grooves 26 on both ends of the side walls of the slider 25, the slide grooves 26 are slidably connected to the inner wall of the limiting groove 24, a clamping plate 27 is fixedly installed on the top of the slider 25, and the inner wall of the clamping plate 27 is provided with an integrally formed anti-slip pattern.

[0034] It should be noted that when the slider 25 slides to a specified position, the clamping plate 27 will move to a corresponding position to clamp the object. Since the inner wall of the clamping plate 27 has anti-slip texture, the object can be kept stable during the clamping process and is not easy to slip or loosen.

[0035] See also Figure 4 , including a second fixed column 32 fixedly installed at the bottom of the slider 25, a fixed column 31 fixedly installed at the bottom of the rotating disk 29, and two ends of the connecting rod 4 28 are rotatably connected with the fixed column 31 and the second fixed column 32.

[0036] It should be noted that the rotational connection of the connecting rod 4 28 allows a certain relative movement between the slider 25 and the rotating disk 29. This relative movement allows the slider 25 to maintain a certain position while being able to make corresponding adjustments as the rotating disk 29 rotates.

[0037] See also Figure 1 , Figure 2 , including a rotating shaft 5 fixedly installed on the inner wall of the raised end of the cam 3, the outer wall of the rotating shaft 5 is rotatably connected to the inner wall of the end of the connecting rod 6, and a rotating shaft 2 7 is rotatably installed at the connection between the connecting rod 1 6, the connecting rod 2 8, and the connecting rod 3 9.

[0038] It should be noted that: due to the use of a rotational connection method, the rotation of the cam 3 can be efficiently transmitted to the connecting rod mechanism, reducing the loss of energy during the transmission process.

[0039] Working principle: Place the ceramic material on the surface of the slider 25, then start the motor 2 30. The rotation of the motor 2 30 will drive the rotating disk 29 to rotate. Since the rotating disk 29 is connected to the connecting rod 4 28, the transmission of the connecting rod 4 28 will make the slider 25 move along the limit groove 24 toward the rotating disk 29. As the slider 25 moves, the clamping plate 27 will gradually approach and stably clamp the ceramic material. When the ceramic material is stably clamped, start the motor 1 4. The drive of the motor 1 4 will cause the cam 3 to start rotating. As the cam 3 rotates, the connecting rod 1 6 will drive the connecting rod 3 9 to transmit, so that the slide bar 16 slides back and forth up and down inside the sleeve 17, thereby generating vibration. , stress relief is performed on the ceramic material. When most of the stress inside the ceramic material is eliminated, the stress relief effect can be further adjusted by rotating the rotating handle 14. The rotation of the rotating handle 14 will drive the vertical bevel gear 21 to engage the horizontal bevel gear 13 to rotate. The horizontal bevel gear 13 is connected to the screw 12. Therefore, the rotation of the screw 12 will cause the slide column 11 to slide inside the arc-shaped slide plate 10. This sliding changes the angle between the connecting rod 1 6 and the connecting rod 3 9 through the connecting rod 2 8. As the angle changes, the stroke of the sliding rod 16 moving up and down will also change, so that the stroke of the sliding rod 16 is shortened, thereby more finely reducing the tiny stress inside the ceramic material.

[0040] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
