Description

Technical Field

[0001] This utility model relates to the field of valve block processing technology, and in particular to a thick plate fixture for valve block processing. Background Technology

[0002] When processing valve blocks, it is necessary to cut blocks of the appropriate size from thick plates. During cutting, the sides of the plate need to be machined using a planer. While machining on the planer, the plate is placed on a mounting base with multiple inverted T-shaped slots open at both ends. To prevent the plate from moving and affecting the machining process, a clamp is often used to restrain it. Existing clamp structures generally include a vertical screw with a lower cap that fits into a slot, a pressure plate fitted onto the vertical screw, and a slotted hole through which the vertical screw passes. Multiple steel ingots are placed on the lower side of the outer end of the pressure plate, which is then placed on the mounting base. The lower wall of the inner end of the pressure plate is then tightened to abut against the upper side of the plate for positioning. However, this method suffers from a small clamping contact area and lacks the ability to constrain the side walls of the plate, resulting in poor clamping stability. Utility Model Content

[0003] This utility model provides a thick plate clamp for valve block processing, which solves the shortcomings of the prior art and solves the problems in plate clamping and positioning, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A clamping fixture for machining thick plates for valve blocks includes a rectangular base plate with a lower shaft rotatably mounted on it. An end nut is threadedly connected to the lower shaft. A circular groove is formed in the lower wall of the base plate, and the end nut is located within the groove. A lead screw is mounted on the upper end of the lower shaft, and a side block is fitted onto the lead screw. A protruding plate is welded to the outer wall of the side block. Rotating side plates are rotatably mounted on both sides of the outer ends of the protruding plates via hinge shafts. A rotating block is welded to the outer ends of the rotating side plates. A clamping lead screw is rotatably mounted within the rotating block. A limit nut is threadedly connected to the lower end of the clamping lead screw, and the limit nut is located at the upper and lower ends of the rotating block. A rotating column is connected to the top via a threaded connection. Connecting screws are connected to both ends of the rotating column via threaded connections. A threaded sleeve is connected to the lead screw via a threaded connection. A pair of hinge screws are connected to the outer circumference of the threaded sleeve via a threaded connection. A rotating plate is fitted over the threaded sleeve. A first hole is formed through the top and bottom of the rotating plate. The threaded sleeve is located in the first hole. A second hole is formed through the left and right sides of the rotating plate. The second hole is located on both sides of the first hole. The hinge screw passes through the first hole. An end groove is formed on the outer end of the rotating plate. A third hole is formed on both sides of the end groove. The shank of the connecting screw passes through the third hole.

[0005] Furthermore, a pair of connecting protrusions are welded to the lower inner wall of the rotating plate, and a pair of connecting side plates are rotatably provided on both sides of the lower end of the connecting protrusions via a connecting shaft, with clamps welded to the lower end of the connecting side plates.

[0006] Furthermore, the upper end of the clamping screw is formed with a patterned rotating head.

[0007] Furthermore, the upper end of the lead screw is formed with a rotating cap with a patterned outer perimeter.

[0008] The advantages of the above technical solution are: This invention improves the stability of clamping the plate by rotating a clamping plate on the clamping end of the rotating plate, thereby increasing the contact area with the plate.

[0009] This invention improves the stability of the board's positioning by fitting a side block to limit the side wall of the board.

[0010] When clamping, the height of the rotating plate can be adjusted according to the thickness of the plate. During clamping, the inner end of the rotating plate can be rotated around the axis of the hinge screw by rotating the clamping screw, so that the clamping plate abuts against the upper side of the plate, thereby achieving the purpose of fixing and constraining the plate. After fixing, the clamping screw is inclined, so it has strong stability. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0013] Figure 2 A three-dimensional structural diagram of a fixture for sheet metal processing is shown. Detailed Implementation

[0014] like Figures 1-2As shown, a thick plate jig for valve block processing includes a rectangular base plate 30. A lower shaft 31 is rotatably mounted on the base plate 30, and an end nut 32 is threadedly connected to the lower shaft 31. A circular groove is formed on the lower wall of the base plate 30, and the end nut 32 is located in the circular groove. A lead screw 33 is provided at the upper end of the lower shaft 31. A rotating cap 34 with a patterned outer circumference is formed at the upper end of the lead screw 33. A side block 43 is sleeved on the lead screw 33. A protruding plate 44 is welded to the outer wall of the side block 43. Rotating side plates 46 are rotatably mounted on both sides of the outer end of the protruding plate 44 through hinge shafts 45. A rotating block 47 is welded to the outer end of the rotating side plate 46. A clamping lead screw 49 is rotatably mounted inside the rotating block 47. A patterned rotating head 52 is formed at the upper end of the clamping lead screw 49, and a limit nut 48 is threadedly connected to the lower end of the clamping lead screw 49. The limiting nut 48 is located at the upper and lower ends of the rotating block 47. The clamping screw 49 is connected to the rotating column 50 by threads. The two ends of the rotating column 50 are connected to the connecting screw 51 by threads. The screw 33 is connected to the threaded sleeve 35 by threads. A pair of hinge screws 36 are connected to the outer periphery of the threaded sleeve 35 by threads. The threaded sleeve 35 is covered by a rotating plate 37. The rotating plate 37 has a first hole 38 that runs through it vertically. The threaded sleeve 35 is located in the first hole 38. The rotating plate 37 has a second hole 39 that runs through it horizontally. The second hole 39 is located on both sides of the first hole 38. The hinge screws 36 pass through the first hole 38. The outer end of the rotating plate 37 has an end groove 53 formed by opening. The two sides of the end groove 53 have a third hole 54. The rod part of the connecting screw 51 passes through the third hole 54.

[0015] A pair of connecting protrusions 40 are welded to the lower inner wall of the rotating plate 37. A pair of connecting side plates are rotatably provided on both sides of the lower end of the connecting protrusions 40 via the connecting shaft 41. A clamping plate 42 is welded to the lower end of the connecting side plates.

[0016] In this embodiment, the plate 2 is hoisted and transferred to the planer's mounting seat 1. Then, multiple clamps are installed in the multiple slots 10 at the plate 2's placement location. During installation, the base plate 30 is placed in the slot 10 and moved inward so that the inner wall of the side block 43 abuts against the side wall of the plate.

[0017] Next, based on the thickness of the plate 2, the operator, while holding the rotating plate 37, rotates the lead screw 33. When the lead screw 33 rotates, it causes the rotating plate 37 to move downwards until the clamping plate 42 moves downwards a certain distance. After moving, the rotating plate 37 is still above the plate 2. Then, the rotating plate 37 is moved inwards so that the clamping plate 42 is above the plate 2. Then, the operator rotates the clamping lead screw 49. When rotating, the distance between the rotating block 47 and the rotating column 50 increases. When the distance between the two increases, the rotating plate 37 rotates around the hinge screw 36, and the lower wall of the clamping plate 42 abuts against the upper wall of the plate 2, thus completing the constraint and positioning of the plate 2.

[0018] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
