Abstract
Description
Technical Field
[0001] This utility model relates to the field of core processing technology, and in particular to a combination clamp that can hold multiple types of cores. Background Technology
[0002] Clay core clamps are used in sand casting in the foundry industry. Their main function is to fix the clay core, which is the part that forms the internal cavity of the casting during the casting process. Through the clay core clamp, the position of the clay core can be kept accurate and displacement can be prevented when pouring metal.
[0003] Currently, with the development of the casting industry towards high precision and multiple varieties, the clay core, as a key component in the forming of castings, has seen a significant increase in the complexity of its shape and the diversity of its dimensions. Existing fixtures cannot accommodate various sizes of clay cores, requiring the replacement of fixtures of different sizes, which is time-consuming, labor-intensive, and increases costs. Furthermore, many new clay cores have irregular shapes, making it difficult for existing fixtures to adjust their shape, which leads to the easy detachment of existing fixtures when clamping irregular clay cores. In addition, existing fixtures usually require manual assistance for positioning, which is time-consuming, labor-intensive, and complex to operate. Therefore, a combined fixture that can clamp multiple types of clay cores is provided. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined clamp that can hold multiple types of cores.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A combination clamp for clamping various types of cores includes a base, a fixed seat fixedly connected to one side of the base, a positioning V-block fixedly connected to the upper side of the fixed seat, a support frame fixedly connected to the outer side of the positioning V-block, a top plate fixedly connected to the upper side of the support frame, a movable plate slidably connected to the lower side of the top plate, and multiple clamping plates installed between the movable plate and the fixed seat. The clamping plates are arranged in pairs, and are connected to the movable plate and the fixed seat respectively through an adjustment component. The adjustment component includes two slide rails, arranged in pairs. One set of slide rails is fixedly connected to the movable plate, and the other set of slide rails is fixedly connected to the fixed seat. A sliding plate is slidably connected within each set of slide rails, and the sliding plate is fixedly connected to the clamping plate. Each end of the sliding plate is fixedly connected to a stop, and a positioning pin is threaded to the outer side of the stop.
[0007] Preferably, a control assembly is installed on the lower side of the top plate. The control assembly includes multiple vertical slide grooves opened on the side wall of the top plate. A slide rod is slidably connected in each vertical slide groove. The slide rod is fixedly connected to a moving plate, and a return spring is fixedly connected between the slide rod and the side wall of the vertical slide groove. Multiple screws are threaded into the top plate.
[0008] Preferably, a buffer assembly is installed inside the clamping plate. The buffer assembly includes multiple dampers fixedly installed inside the clamping plate. A connecting plate is fixedly connected to the outside of each damper. A damping spring is fixedly connected to the outside of the connecting plate. A clamping plate is fixedly connected to the outside of the damping spring.
[0009] Preferably, a motor is fixedly connected above the base, and two rotating shafts are rotatably connected to the upper side of the base. One of the rotating shafts is fixedly connected to the output end of the motor, and a conveyor belt is connected to the outer side of both rotating shafts for transmission.
[0010] Preferably, an anti-slip rubber sheet is fixed inside the clip.
[0011] Preferably, multiple shock-absorbing pads are fixedly installed on the lower side of both the base and the fixing seat.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. First, when it is necessary to clamp the clay core, the moving plate is adjusted to move the clamping plate up and down. During the movement, a certain assistance effect is formed under the action of the return spring. Finally, it is fixed with screws. The distance between the upper and lower clamping plates can be adjusted, so that clay cores of different sizes can be easily clamped. The operation is simple and cost-saving.
[0014] 2. Furthermore, by adjusting the position of the clamping plate through the slide rail and slide plate, it can adapt to cores of different shapes. Then, by fine-tuning the damper and damping spring, it can further adapt to irregular cores, reducing the possibility of core falling off.
[0015] 3. Finally, driven by the motor and conveyor belt, the mud core to be clamped is moved between the clamping plates, and the mud core is positioned by the positioning V-block, which saves time and effort and is simple to operate. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Reference Figures 1-5 A combination clamp capable of holding various types of cores includes a base 1 and a fixed seat 10. Multiple shock-absorbing pads are fixedly installed on the lower sides of both the base 1 and the fixed seat 10. These not only provide support for the base 1 and the fixed seat 10 but also reduce the adverse effects on nearby workpieces during overall operation on the upper side of the base 1 and the fixed seat 10, thus reducing vibration. The base 1 and the fixed seat 10 are fixedly connected. A positioning V-block 22 is fixedly connected to the upper side of the fixed seat 10. A support frame 5 is fixedly connected to the outer side of the positioning V-block 22. A top plate 8 is fixedly connected to the upper side of the support frame 5. A movable plate 9 is slidably connected to the lower side of the top plate 8. Multiple... Clamping plates 16 are arranged in pairs. The clamping plates 16 are connected by an adjustment assembly, a movable plate 9, and a fixed base 10. The adjustment assembly includes two slide rails 17, which are arranged in pairs. One set of slide rails 17 is fixedly connected to the movable plate 9, and the other set of slide rails 17 is fixedly connected to the fixed base 10. A slide plate 11 is slidably connected in each set of slide rails 17, and the slide plate 11 is fixedly connected to the clamping plate 16. Each end of each slide plate 11 is fixedly connected to a stop block 14. A positioning pin 13 is threadedly connected to the outside of the stop block 14. The positioning pin 13 is rotated until it abuts against the slide rail 17, thereby fixing the slide plate 11 and the stop block 14 as a whole.
[0024] A control assembly is installed on the lower side of the top plate 8. The control assembly includes multiple vertical slide grooves 6 opened on the side wall of the top plate 8. A slide rod 21 is slidably connected in each vertical slide groove 6. The slide rod 21 is fixedly connected to the moving plate 9. A return spring 20 is fixedly connected between the slide rod 21 and the side wall of the vertical slide groove 6. Multiple screws 7 are threaded in the top plate 8. The position of the moving plate 9 relative to the top plate 8 is adjusted and fixed by the screws 7.
[0025] A buffer assembly is installed inside the clamping plate 16. The buffer assembly includes multiple dampers 18 fixedly installed inside the clamping plate 16. A connecting plate 19 is fixedly connected to the outside of the damper 18. A damping spring 15 is fixedly connected to the outside of the connecting plate 19. A clamping plate 12 is fixedly connected to the outside of the damping spring 15. The dampers 18 and the damping spring 15 can consume energy and slow down the movement. When the clamping plate 16 moves downward, it can protect the mud core and stabilize the clamping effect.
[0026] A motor 3 is fixedly connected to the top of the base 1. Two rotating shafts 2 are rotatably connected to the upper side of the base 1. One of the rotating shafts 2 is fixedly connected to the output end of the motor 3. The outer sides of the two rotating shafts 2 are connected to a conveyor belt 4 for transmission. The conveyor belt 4 is used to transport the mud core that needs to be clamped to multiple clamping plates 16.
[0027] In this utility model, when it is necessary to install the clay core, the specific operation is as follows: First, select the appropriate clay core according to the actual work requirements, and then place the clay core to be clamped on the conveyor belt 4. Start the motor 3 first, and the motor 3 drives the conveyor belt 4 to rotate through the rotating shaft 2. The conveyor belt 4 transports the clay core between multiple clamping plates 16. When the clay core enters between multiple clamping plates 16, the clay core is first positioned by the positioning V-block 22 to prevent the clay core from moving again and reduce the workload of manual positioning by the staff. After the clay core is positioned, rotate the screw 7 to drive the overall moving plate 9 to move downward until the clamping pieces 12 or most of the clamping pieces 12 in the multiple clamps 16 are in contact with the clay core, thereby completing the clamping and fixing effect of the clay core.
[0028] In the above-mentioned work process, before placing the core, the position of the clamping plate 16 is adjusted according to the actual shape and size of the core. That is, the slide plate 11 is moved along the slide rail 17, and the slide plate 11 drives the clamping plate 16 to move. When the position of the clamping plate 16 meets the work requirements, the positioning pin 13 is rotated until the other end of the positioning pin 13 abuts against the slide rail 17, thereby completing the adjustment and fixing of the position of the clamping plate 16.
