Description

Technical Field

[0001] This utility model relates to the field of honeycomb ceramic carrier mold processing technology, specifically an adjustable fixture for processing asymmetric honeycomb ceramic carrier molds. Background Technology

[0002] Honeycomb ceramic carriers are core components of products such as automotive exhaust purification catalysts and diesel particulate filters, and their molds are key process equipment for manufacturing these carriers.

[0003] For example, patent application number 202321167980.5 published on the China Patent Network, entitled "An Adjustable Fixture for Processing Asymmetric Honeycomb Ceramic Carrier Molds," includes an operating table. Two dustproof boxes are mounted on the top of the operating table. Two guide rods are horizontally fixedly connected to the inner cavity of each dustproof box. A movable plate is slidably connected to the surface of each guide rod. A limit rod is fixedly connected to the end of each guide rod away from the inner wall of the dustproof box. This invention adjusts the distance between the two fixtures by moving the dustproof box, causing a T-shaped slider to slide within the inner cavity of the second slide groove. This allows it to be used with molds of various specifications. When fixing the mold, the rotation of the motor causes the movable plate, which works in conjunction with the sliding pin, rotating disk, and connecting shaft, to slide on the surface of the guide rods. The movable plate, through the connecting rod, fixes the mold with the movable clamp plate around the connection point of the limit rod, thus achieving the purpose of fixing molds of various specifications efficiently.

[0004] However, the existing fixtures have a relatively simple adjustment method, which can only adjust the positioning thickness. When it is necessary to fix an asymmetric honeycomb ceramic carrier mold, the relatively set fixtures cannot be controlled in a targeted manner, which affects the scope of application.

[0005] Therefore, it is necessary to design and modify the adjustable fixture used for processing asymmetric honeycomb ceramic carrier molds. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable fixture for processing asymmetrical honeycomb ceramic carrier molds. This fixture has the advantage of being able to be adjusted asymmetrically, solving the problem that the existing fixtures have a relatively simple adjustment method, which can only adjust the positioning thickness. When it is necessary to fix the asymmetrical honeycomb ceramic carrier mold, the relatively set fixture cannot be controlled in a targeted manner, thus affecting the scope of application.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable fixture for processing asymmetric honeycomb ceramic carrier molds, including a base plate; Clamping structures are provided at the four corners of the top of the base plate, and openings are provided on both sides of the top of the base plate. A slider located inside the opening is fixedly connected to the bottom of the clamping structure. The slider is slidably connected to the opening. A fixing structure is provided at the bottom of the base plate, which can clamp and fix the slider.

[0008] As a preferred embodiment of this utility model, the fixing structure includes a connecting frame fixedly connected to the bottom of the base plate. A bidirectional screw is movably connected inside the connecting frame via a bearing. Both sides of the surface of the bidirectional screw are threaded with a screw sleeve. Both sides of the bottom of the screw sleeve are movably connected with a crank via a pin. A pressure plate is movably connected to the side of the crank away from the screw sleeve via a pin. The outer side of the pressure plate contacts the inner side of the slider.

[0009] In a preferred embodiment of this invention, the top of the threaded sleeve is wrapped around the surface of the connecting frame, and the threaded sleeve and the connecting frame are slidably connected.

[0010] As a preferred embodiment of this utility model, both sides of the bottom of the base plate are fixedly connected to brackets located outside the pressure plate, and the inner side of the brackets is movably connected to a support plate via a pin. The side of the support plate away from the brackets extends to the bottom of the slider.

[0011] In a preferred embodiment of this invention, a force-bearing plate is fixedly connected to the side of the support plate near the bracket, and a push rod located inside the force-bearing plate is fixedly connected to the bottom of the pressure plate, with the outer surface of the push rod in contact with the surface of the force-bearing plate.

[0012] As a preferred embodiment of this utility model, elastic plates are fixedly connected to both sides of the top of the support plate, and the side of the elastic plate away from the support plate contacts the bottom of the base plate, and the elastic plate is elastic.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model forms an independently adjustable fixture base by setting fixture structures at the four corners of the top of the base plate, opening the bottom, and connecting with a slider. It realizes the asymmetrical movement and positioning function of the four fixture structures, and solves the problem that traditional fixtures can only be adjusted symmetrically and cannot adapt to asymmetrical mold contours.

[0014] 2. This utility model uses a transmission mechanism composed of a bidirectional screw, a screw sleeve, a crank, and a pressure plate to convert a single rotary input into synchronous opposite movements of the two pressure plates, thereby achieving the function of clamping and fixing the slider from both sides simultaneously through one operation, improving operating efficiency and ensuring symmetrical balance of clamping force.

[0015] 3. The present invention increases the contact area between the screw sleeve and the connecting frame by wrapping the top of the screw sleeve with the connecting frame and sliding connection, thereby enhancing the movement stability and load-bearing rigidity of the screw sleeve and preventing the screw sleeve from deflecting or jamming when the bidirectional screw rotates.

[0016] 4. This utility model, through the bracket and support plate structure, provides upward support from the bottom of the slider while the pressure plate presses the slider from the inside, realizing bidirectional constraint on the slider, enhancing the fixation reliability, and preventing the slider from loosening due to vibration during processing.

[0017] 5. This utility model uses a push rod and a force plate contact structure to convert the horizontal movement of the pressure plate into an upward pushing force on the support plate, thereby achieving the linkage effect of lateral clamping and bottom support, and ensuring the synchronicity and coordination of the fixing action.

[0018] 6. This utility model uses a spring plate structure to provide a continuous preload to the support plate by utilizing its elastic properties. This can keep the support plate in a reset state for easy adjustment when it is not fixed, and can also play a role in buffering and compensating for gaps when it is fixed, thereby enhancing the adaptability and stability of the system.

[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] like Figures 1 to 4 As shown, the present invention provides an adjustable fixture for processing asymmetric honeycomb ceramic carrier molds, including a base plate 1; The four corners of the top of the base plate 1 are provided with clamping structures 2, and the two sides of the top of the base plate 1 are provided with openings 3. The bottom of the clamping structure 2 is fixedly connected to a slider 4 located inside the opening 3. The slider 4 is slidably connected to the opening 3. The bottom of the base plate 1 is provided with a fixing structure that can clamp and fix the slider 4.

[0023] refer to Figure 2 The fixed structure includes a connecting frame 5 fixedly connected to the bottom of the base plate 1. A bidirectional screw 6 is movably connected inside the connecting frame 5 via a bearing. Both sides of the surface of the bidirectional screw 6 are threaded with screw sleeves 7. Both sides of the bottom of the screw sleeves 7 are movably connected with cranks 8 via pins. A pressure plate 9 is movably connected to the side of the crank 8 away from the screw sleeves 7 via a pin. The outer side of the pressure plate 9 contacts the inner side of the slider 4.

[0024] As a technical optimization of this utility model, the transmission mechanism composed of a bidirectional screw 6, a screw sleeve 7, a crank 8 and a pressure plate 9 converts a single rotary input into synchronous opposite movement of the two pressure plates 9, realizing the function of clamping and fixing the slider 4 from both sides at the same time through one operation, improving the operating efficiency and ensuring the symmetrical balance of the clamping force.

[0025] refer to Figure 3 The top of the threaded sleeve 7 is wrapped around the surface of the connecting frame 5, and the threaded sleeve 7 and the connecting frame 5 are slidably connected.

[0026] As a technical optimization of this utility model, the structure of wrapping the top of the threaded sleeve 7 around the connecting frame 5 and slidingly connecting it increases the contact area between the threaded sleeve 7 and the connecting frame 5, thereby enhancing the movement stability and load-bearing rigidity of the threaded sleeve 7 and preventing the threaded sleeve 7 from deflecting or jamming when the bidirectional screw 6 rotates.

[0027] refer to Figure 4 Both sides of the bottom of the base plate 1 are fixedly connected to the brackets 10 located outside the pressure plate 9. The inner side of the brackets 10 is movably connected to the support plate 11 via a pin. The side of the support plate 11 away from the brackets 10 extends to the bottom of the slider 4.

[0028] As a technical optimization of this utility model, the structure of bracket 10 and support plate 11 provides upward support from the bottom of slider 4 while the pressure plate 9 presses the slider 4 from the inside, thereby realizing bidirectional constraint on slider 4, enhancing the fixation reliability, and preventing slider 4 from loosening due to vibration during processing.

[0029] refer to Figure 4 A force-bearing plate 12 is fixedly connected to the side of the support plate 11 near the bracket 10. A push rod 13 located inside the force-bearing plate 12 is fixedly connected to the bottom of the pressure plate 9. The outer surface of the push rod 13 is in contact with the surface of the force-bearing plate 12.

[0030] As a technical optimization of this utility model, the horizontal movement of the pressure plate 9 is converted into an upward pushing force on the support plate 11 by the contact and cooperation structure between the push rod 13 and the force plate 12, thereby realizing the linkage effect of lateral clamping and bottom support and ensuring the synchronicity and coordination of the fixing action.

[0031] refer to Figure 4 Both sides of the top of the support plate 11 are fixedly connected with spring plates 14. The side of the spring plate 14 away from the support plate 11 contacts the bottom of the base plate 1. The spring plate 14 is elastic.

[0032] As a technical optimization of this utility model, the elastic plate 14 structure provides a continuous preload force to the support plate 11 by utilizing its elastic properties. This not only keeps the support plate 11 in a reset state for easy adjustment when it is not fixed, but also plays a role in buffering and compensating for gaps when it is fixed, thereby enhancing the adaptability and stability of the system.

[0033] The working principle and usage process of this utility model are as follows: First, the asymmetric mold is placed on the top of the base plate 1. The clamping structures 2 at the four corners are manually adjusted according to the mold outline. The sliders 4 at the bottom of each clamping structure 2 can slide independently within the opening 3 of the base plate 1, thereby achieving asymmetric positioning to adapt to molds of different shapes. After positioning, the two-way screws 6 at the bottom of the base plate 1 are rotated to drive the two screw sleeves 7 to move towards each other. The screw sleeves 7 push the pressure plate 9 inward to press the inner side of the slider 4 through the crank 8. At the same time, the push rod 13 at the bottom of the pressure plate 9 abuts against the force plate 12 on the support plate 11, causing the support plate 11 to rotate upward around the pin axis and support the slider 4 from the bottom. During this process, the elastic spring provides pre-tightening force. Finally, through the coordinated action of the pressure plate 9 and the support plate 11, the slider 4 is firmly locked in the set position, completing the flexible clamping and rigid fixation of the asymmetric mold.

[0034] In summary, this adjustable fixture for processing asymmetrical honeycomb ceramic carrier molds, through the fixture structures 2 set at the four corners of the top of the base plate 1, the openings 3 at the bottom, and the connection of the sliders 4, forms an independently adjustable fixture base, realizing the asymmetrical moving and positioning function of the four fixture structures 2, and solving the problem that traditional fixtures can only be adjusted symmetrically and cannot adapt to asymmetrical mold contours.
