Description

Technical Field

[0001] The utility model belongs to the technical field of cast iron flat plates, in particular to a large-section grey cast iron flat plate structure. Background Art

[0002] The cast iron flat plate platform is referred to as the flat plate platform, also known as cast iron flat plate, cast iron platform, flat plate and platform. The overall structure of the cast iron flat plate platform is basically box-type and ribbed plate type. According to the precision processing, it can be divided into two types: precision planing and scraping. The working surface of the flat plate platform can be processed with V-shaped, T-shaped, U-shaped grooves, dovetail grooves, round holes and long holes. It is a plane reference measuring tool used for workpiece and equipment inspection, marking, assembly, welding, assembly and riveting.

[0003] The patent with announcement number CN217990931U discloses a cast iron platform for workpiece production with a base having a heating function. The cast iron platform is provided with a first inverted T-shaped groove, a second inverted T-shaped groove and a first sliding block and a second sliding block matched therewith, because the first sliding block is located inside the first inverted T-shaped groove and can slide within the limit range of the first inverted T-shaped groove, and then cooperates with the second inverted T-shaped groove and the second sliding block inside it to achieve the limit of the iron within the limited range to help further cast iron work. When the first sliding block and the second sliding block slide to a determined position, the forward and reverse motor inside the inverted T-shaped connector operates to make the gear fixedly connected to its output end rotate, thereby driving the first L-shaped rack and the second L The rack is displaced to both sides to fix the first sliding block in the determined position. The same principle applies to the second sliding block. I will not elaborate on it here. When the first sliding block and the second sliding block are positioned, the staff can rotate the hand plate by hand. Because the other end of the rotating hand plate is fixedly connected to the rotating shaft and the threaded shaft, the rotating shaft and the threaded shaft start to rotate. Because the threaded shaft passes through one end of the linkage rod, and the internal shape of the hole through which it passes matches the pattern on the surface of the threaded shaft, when the threaded shaft rotates, the linkage rod will be horizontally displaced to one side, thereby displacing the linkage plate fixedly connected to the other end of the linkage rod, thereby clamping and releasing the cast iron. A total of 8 first inverted T-shaped grooves are opened on the cast iron platform to accommodate different cast iron widths.

[0004] The above-mentioned cast iron platform for workpiece production with a base having a heating function can solve the corresponding technical problems, but its first sliding block and second sliding block are fixed in a determined position by the operation of the forward and reverse motors inside them respectively. Not only is the structure relatively complicated and not conducive to subsequent maintenance and repair, but the first inverted T-shaped groove and the second inverted T-shaped groove are arranged on the top of the cast iron platform, resulting in debris and other impurities easily falling into the first inverted T-shaped groove and the second inverted T-shaped groove during the workpiece processing, affecting the sliding of the first sliding block and the second slider, thereby reducing the use effect of the cast iron platform.

The cast iron platform 2 is installed on the top of the support 1, the clamping assembly 3 is movably arranged on the top of the cast iron platform 2, and the displacement assembly 4 is arranged on the cast iron platform 2.

[0029] See attached Figure 1 、 2 As shown, the displacement assembly 4 includes a first side groove 41 opened on one side of the cast iron platform 2, and the inner cavity of the first side groove 41 is installed with a rodless cylinder 42. A convex plate 43 is provided on both sides of the bottom of the clamping assembly 3, and the opposite sides of the two convex plates 43 are in contact with the cast iron platform 2. The slide of the rodless cylinder 42 is fixedly connected to one side of one of the convex plates 43. A second side groove 44 parallel to the first side groove 41 is opened on the other side of the cast iron platform 2, and a slider 45 is slidably connected to the inner cavity of the second side groove 44, and one side of the slider 45 is fixedly connected to one side of the other convex plate 43.

[0030] The rodless cylinder 42 is started, and the slide of the rodless cylinder 42 drives the convex plate 43, the clamping assembly 3 and the slider 45 to move synchronously along the length direction of the first side groove 41. The slider 45 slides in the inner cavity of the second side groove 44, and the clamping assembly 3 slides on the top of the cast iron platform 2, and the clamping assembly 3 can be moved to the required position according to the size of the workpiece; the workpiece is placed between the two clamping plates 32, and the stepping motor 331 is started.

The rubber pad 321 has the same shape and size as the clamping plate 32. The rubber pad 321 can not only improve the clamping stability of the clamping plate 32, but also protect the surface of the workpiece.

[0033] In order to drive the two splints 32 to move synchronously toward or away from each other, in an embodiment of the utility model, the driving member 33 includes a stepper motor 331 fixedly connected to the outer surface of the shell 31, and the output shaft of the stepper motor 331 passes through the inner cavity of the shell 31 and is fixedly connected to a bidirectional screw 332.

[0036] In order to improve the stability of the bidirectional screw 332 during rotation, the end of the bidirectional screw 332 away from the stepping motor 331 is rotatably connected to the inner wall surface of the shell 31 through a bearing, and a support sleeve 336 is fixedly connected to the center of the inner cavity of the shell 31. The inner wall surface of the support sleeve 336 is rotatably connected to the surface of the bidirectional screw 332 through a bearing.
