Description

Technical Field

[0001] This utility model relates to the field of foam ceramic filter processing technology, and in particular to a packing clamp. Background Technology

[0002] Foam ceramic filters used in metallurgical casting are often rectangular or circular in structure. To prevent damage from shaking or impact during transportation, rectangular foam ceramic filters typically require a flexible buffer ring to be placed over each set of filters before packing. However, because the set of filters is not secured during the installation of the flexible buffer ring, some filters are prone to misalignment, making the installation process difficult. Utility Model Content

[0003] This utility model provides a packing clamp to overcome the shortcomings of the prior art. It can fix a set of foam ceramic filters to facilitate the fitting of flexible buffer rings and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A packing clamp includes a long strip with vertical side plates bent downwards at both ends. A concave plate is formed at the lower end of the vertical side plates, and two pairs of horizontal guide rods are inserted through the concave plate. Clamping recesses are welded to the inner ends of the horizontal guide rods. The clamping recesses are located inside the concave plate and can act on both ends of a set of foam ceramic filters to fix the foam ceramic filters, so as to facilitate the installation of flexible buffer rings.

[0006] Furthermore, a concave seat is welded to the lower end of the outer wall of the vertical side plate, and an extended shaft is coaxially welded to the outer end of the concave seat. A swing V-plate is rotatably mounted on the extended shaft, and a roller is rotatably mounted on the inner end of the swing V-plate. An inner pressure roller is fixed to the inner end of the roller. An inner top vertical plate is formed at the upper end of the clamping concave part. The outer circumference of the inner pressure roller is tightly attached to the outer wall of the inner top vertical plate. A transverse spring is sleeved on the horizontal guide rod, and an end cap is provided at the outer end of the horizontal guide rod. The transverse spring is located between the end cap and the concave plate. When the swing V-plate and the inner pressure roller at its inner end rotate downward, they can act on the inner top vertical plate, thereby causing the inner wall of the clamping concave part to abut against both ends of a set of foam ceramic filters, thus improving the fixing effect of the foam ceramic filters.

[0007] Furthermore, the outer ends of the extended shaft and the roller are respectively connected to limit nuts by threads. The limit nuts are located on the outside of the swing V-plate to ensure the connection stability between the extended shaft, the roller and the swing V-plate.

[0008] Furthermore, an elongated hole is provided on the outer end of the swing V-plate, and a movable rod is movably installed in the elongated hole. A constraint nut is threadedly connected to the outer end of the movable rod, and the constraint nut is located on the outer side of the swing V-plate. A V-shaped arm is rotatably installed on the movable rod, and the V-shaped arm is located on the inner side of the swing V-plate. The inner ends of the V-shaped arms at the same end are connected by a forming connecting plate, and a through rod is threadedly connected to the connecting plate. A vertically arranged strip-shaped hole is provided on the vertical side plate, and the through rod passes through the strip-shaped hole. An upper lifting plate is movably installed between the vertical side plates, and the upper lifting plate is located below the elongated plate. The inner ends of the through rod are threadedly connected to both ends of the upper lifting plate. The V-shaped arm can move vertically. During its upward movement, it can cause the movable rod to act on the elongated hole, thereby causing the clamping recess to move inward. Since the V-shaped arm is set on the upper lifting plate, it can cause the clamping recess to move inward synchronously.

[0009] Furthermore, a pair of baffles are formed at the upper end of the inner top vertical plate. The baffles limit the inner pressure roller and prevent the inner end of the swing V plate from rotating excessively upward.

[0010] Furthermore, a pair of vertical inserts are welded to the lifting plate, the vertical inserts pass through the long strip plate, and a vertical spring is fitted on the vertical insert. The vertical spring is located between the long strip plate and the lifting plate. A limit cap is provided at the upper end of the vertical insert. The elastic force provided by the vertical spring and the horizontal spring keeps it in an open state before a set of foam ceramic filters is fixed.

[0011] Furthermore, an L-shaped plate is formed at the lower end of the vertical section of the clamping recess. The inner wall of the L-shaped plate serves to limit the two sides of a set of foam ceramic filters, so as to ensure the stability of the limiting of a set of foam ceramic filters.

[0012] The advantages of the above technical solution are:

[0013] This invention can effectively fix multiple foam ceramic filters, i.e., a set of foam ceramic filters, thereby facilitating the escape operation of the flexible buffer ring. Attached Figure Description

[0017] Figure 3 A magnified view of point B is shown. Detailed Implementation

[0018] like Figures 1-3 As shown, a packing clamp includes a long strip 1, with vertical side plates 10 bent downwards at both ends of the long strip 1. A concave plate 200 is formed at the lower end of the vertical side plate 10. Two pairs of horizontal guide rods 33 are passed through the concave plate 200. A clamping recess 36 is welded to the inner end of the horizontal guide rod 33. An L-shaped plate 39 is formed at the lower end of the vertical section of the clamping recess 36. The clamping recess 36 is located inside the concave plate 200.

[0019] A concave seat 2 is welded to the lower end of the outer wall of the vertical side plate 10. An extended shaft 20 is coaxially welded to the outer end of the concave seat 2. A swing V plate 21 is rotatably mounted on the extended shaft 20. A roller 22 is rotatably mounted on the inner end of the swing V plate 21. The outer ends of the extended shaft 20 and the roller 22 are respectively connected by threaded limit nuts. The limit nuts are all located on the outer side of the swing V plate 21. An inner pressure wheel 23 is fixed to the inner end of the roller 22. An inner top vertical plate 37 is formed at the upper end of the clamping concave part 36. The outer periphery of the inner pressure wheel 23 is tightly attached to the outer wall of the inner top vertical plate 37. A pair of baffles 38 are formed at the upper end of the inner top vertical plate 37. A transverse spring 35 is sleeved on the horizontal guide rod 33. An end cap 34 is provided at the outer end of the horizontal guide rod 33. The transverse spring 35 is located between the end cap 34 and the concave plate 200.

[0020] An elongated hole 24 is provided on the outer end of the swing V-plate 21. A movable rod 25 is movably installed in the elongated hole 24. A constraint nut is threadedly connected to the outer end of the movable rod 25. The constraint nut is located on the outer side of the swing V-plate 21. A V-shaped arm 26 is rotatably installed on the movable rod 25. The V-shaped arm 26 is located on the inner side of the swing V-plate 21. The inner ends of the V-shaped arms 26 at the same end are connected by a forming connecting plate 27. A through rod 28 is threadedly connected to the connecting plate 27. A vertically arranged strip hole 11 is provided on the vertical side plate 10. The through rod 28 passes through the strip hole 11. An upper lifting plate 29 is movably installed between the vertical side plates 10. The upper lifting plate 29 is located below the elongated plate 1. The inner ends of the through rod 28 are threadedly connected to both ends of the upper lifting plate 29.

[0021] A pair of vertical rods 30 are welded onto the lifting plate 29. The vertical rods 30 pass through the long strip plate 1. A vertical spring 32 is sleeved on the vertical rods 30. The vertical spring 32 is located between the long strip plate 1 and the lifting plate 29. A limit cap 31 is provided at the upper end of the vertical rods 30.

[0022] In this embodiment, during operation, several foam ceramic filters are first discharged in the manner shown below. Figure 1As shown in the diagram, the operator then moves the clamp onto the set of foam ceramic filters, at which point the clamping recesses 36 are located at both ends of the set of foam ceramic filters, while the L-shaped plates 39 are located on both sides of the set of foam ceramic filters. Next, the operator pulls the lifting plate 29 upwards, causing the lifting plate 29 to drive the V-shaped arm 26 to move upwards synchronously. During the movement, the movable rod 25 acts on the strip hole 11, causing the inner end of the swing V-plate 21 to rotate downwards. During the downward rotation, the outer periphery of the inner pressure roller 23 is pressed tightly against the inner top vertical plate 37, and finally, a section of the inner end of the swing V-plate 21 is in a horizontal position. At this time, the clamping recess 36 will abut against both ends of the foam ceramic filter group, and the inner wall of the L-shaped plate 39 will limit the two sides of the foam ceramic filter group. After that, the operator puts the flexible buffer ring on the foam ceramic filter group and then pulls out the clamp. After that, the clamping recess 36 will return to the open state under the elastic force of the vertical spring 32 and the horizontal spring 35, ready for reuse.
