Description

Technical Field

[0001] This utility model relates to the technical field of concrete precast component production and testing equipment, specifically to a vibration table for a molding machine. Background Technology

[0002] The molding and quality control of precast concrete components are important aspects of prefabricated building production. Vibration tables, as key equipment for uniformly compacting concrete and ensuring the density and mechanical properties of precast components, have been widely used in the production and testing of precast components.

[0003] Currently, when conducting tests on concrete molding, molds of different sizes (test molds) are usually required, and these molds are generally square in structure. However, traditional vibration tables use a fixed clamp design. When changing molds of different lengths and widths, the clamps need to be completely disassembled, then installed and fixed on the appropriate area of ​​the vibration table according to the size of the mold, and then the mold is clamped. This operation is quite inconvenient.

[0004] Therefore, there is an urgent need to design a molding machine vibration table that can clamp and fix molds of different lengths, widths and heights. Utility Model Content

[0005] The purpose of this invention is to provide a molding machine vibration table that can clamp square molds of different lengths, widths and heights, simplifying the mold changing process and ensuring clamping stability during vibration testing.

[0006] The technical solution adopted by this utility model to solve the above problems is: a molding machine vibration table, including a machine base, a positioning plate is connected and fixed on the machine base, and a number of corner clamps for fixing the four corners of the upper end face of a square mold and side clamps for fixing the sides of the square mold are provided on the positioning plate. The clamping height of the corner clamps is adjustable, and the side clamps are slidably and detachably connected to the positioning plate.

[0007] Preferably, the corner clamp includes a fixed seat, a screw, a movable seat, and a driving component. The fixed seat is mounted on a positioning plate. The lower end of the screw is threadedly connected to the fixed seat. The movable seat is slidably connected to the screw and is also damped and rotatably connected to a swing arm. A pressure module is slidably mounted on the swing arm along its length and is fixed in position by a first locking member. The driving component is used to drive the movable seat to rotate the screw relative to the fixed seat, thereby adjusting the height of the movable seat and the swing arm.

[0008] Preferably, the driving component includes an eccentric seat and a driving rod. The upper end of the screw is provided with a hinge seat, which is connected to the eccentric seat by a pin. The upper end of the movable seat is provided with a limit groove, and the hinge seat is rotatably disposed between the side walls on both sides of the limit groove.

[0009] Preferably, the swing arm has a guide groove along its length, the pressure module is provided with a guide seat that is slidably connected to the guide groove, and the first locking member includes a first locking bolt and a fixing ring. The first locking bolt passes through the fixing ring from the upper surface of the swing arm and is screwed to the guide seat.

[0010] Preferably, the side clamp includes a clamp seat and a pressure rod. The clamp seat has an L-shaped cross section, and its bottom is detachably connected to the positioning plate by two sets of second locking members. The positioning plate has several sets of T-shaped sliding grooves at equal intervals. The distance between two adjacent parallel sets of T-shaped sliding grooves is the same as the distance between the two sets of second locking members. The pressure rod is threaded to the side of the clamp seat, and its end is slidably provided with a lever to drive its rotation.

[0011] Preferably, the positioning plate adopts a square design, and the T-shaped groove is set perpendicular to the four sets of side directions of the positioning plate and ends at the diagonal of the positioning plate.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] Example:

[0026] See Figure 1 - Figure 8 In this embodiment, a vibration table for a molding machine is disclosed, which is specifically used for the compaction and testing of precast square concrete molds. Specifically, it includes a machine base 11, on which a positioning plate 12 is connected and fixed. The positioning plate 12 is provided with several sets of corner clamps 14 for fixing the four corners of the upper end face of the square mold 13 and side clamps 15 for fixing the sides of the square mold 13. The clamping height of the corner clamps 14 is adjustable, and the side clamps 15 are slidably and detachably connected to the positioning plate 12.

[0027] Specifically, in this embodiment, four sets of corner clamps 14 are provided, each located at one of the four corners of the positioning plate 12. The corner clamps 14 are primarily used to fix the four corners of the upper surface of the square mold 13, and their clamping height is adjustable to accommodate molds of different heights. The side clamps 15 are used to fix the sides of the square mold 13 and are slidably and detachably connected to the positioning plate 12. The fixing position and number of the side clamps 15 on the positioning plate 12 can be adjusted according to the width of the mold side. Compared with the fixed clamp design of traditional vibration tables, this invention can achieve clamping and fixing of molds of different lengths, widths, and heights without removing the clamps (corner clamps 14 and side clamps 15).

[0028] See Figure 2 - Figure 3 In the specific structure of the corner clamp 14, it includes a fixed base 21, a screw 22, a movable base 23, and a driving component 24. The fixed base 21 is mounted on the positioning plate 12. The lower end of the screw 22 is threadedly connected to the fixed base 21. The movable base 23 is slidably connected to the screw 22 and is also damped and rotatably connected to a swing arm 25. A pressure module 26 is slidably mounted on the swing arm 25 along its length and is fixed in position by a first locking member 27. The driving component 24 drives the movable base 23 to rotate the screw 22 relative to the fixed base 21 to adjust the height of the movable base 23 and the swing arm 25. In practical applications, when it is necessary to clamp square molds 13 of different heights, the height of the swing arm 25 and the pressure module 26 is first adjusted by the driving component 24 according to the height of the mold, so that the bottom surface of the pressure module 26 is slightly higher than the top surface of the mold. Because the swing arm 25 and the movable seat 23 are connected by a damped rotation, the operator can manually adjust the angle of the swing arm 25 to swing it above the four corners of the mold, while simultaneously sliding the pressure module 26 along the length of the swing arm 25 to align the pressure module 26 with the force points at the four corners of the mold. Then, the first locking member 27 quickly fixes the pressure module 26 after determining its position, ensuring that the pressure module 26 will not shift during clamping. In this embodiment, the drive component 24 drives the screw 22 to rotate, causing the movable seat 23 to move up and down along the screw 22, thereby driving the swing arm 25 and the pressure module 26 to rise and fall as a whole to adapt to changes in mold height, allowing the corner clamp 14 to accommodate molds of different heights.

[0029] The driving component 24 includes an eccentric seat 31 and a driving rod 32. A hinge seat 33 is provided at the upper end of the screw 22. The hinge seat 33 is connected to the eccentric seat 31 via a pin 34. A limiting groove 35 is provided at the upper end of the movable seat 23. The hinge seat 33 is rotatably positioned between the side walls 36 on both sides of the limiting groove 35. A return spring 37 is provided between the upper surface of the hinge seat 33 and the limiting groove 35. In this embodiment, the return spring 37 is a tension spring, meaning that there is always elastic tension between the upper surfaces of the hinge seat 33 and the movable seat 23. In actual operation, when it is necessary to adjust the height of the movable seat 23 and the swing arm 25, the movable seat 23 must first be reset. This is done by moving the driving rod 32 to rotate the eccentric seat 31 around the pin 34, causing the return spring 37 to return to its shortest length state. Under the elastic tension of the return spring 37, the movable seat 23 slides upward along the fixed seat 21. Then, the drive rod 32 is moved to drive the screw 22 to rotate relative to the fixed seat 21. Under the threaded connection, the screw 22 extends and retracts relative to the fixed seat 21. Since the side walls 36 of the limiting groove 35 limit the eccentric seat 31, the rotation of the drive rod 32 can also drive the movable seat 23 to rotate at the same time. Thus, the movable seat 23 can also move up and down along the fixed seat 21 with the screw 22, thereby driving the swing arm 25 and the pressure module 26 to rise and fall as a whole.

[0030] The swing arm 25 has a guide groove 41 along its length. The pressing module 26 is equipped with a guide seat 42 that is slidably connected to the guide groove 41. The first locking member 27 includes a first locking bolt 43 and a fixing ring 44. The first locking bolt 43 passes through the fixing ring 44 from the upper surface of the swing arm 25 and is screwed to the guide seat 42. In actual operation, the operator first slides the pressing module 26 along the guide groove 41 of the swing arm 25 according to the position of the four corners of the mold relative to the bottom of the swing arm 25, so that the pressing module 26 moves to a suitable position to press the four corners of the mold. After the position of the pressing module 26 is confirmed, the first locking bolt 43 is tightened, and the fixing ring 44 and the pressing module 26 are respectively pressed against the upper and lower sides of the guide groove 41 of the swing arm 25 by the threaded connection. This allows the position of the pressing module 26 to be adjusted according to the position of the four corners of molds with different length and width dimensions. In this embodiment, the fixing ring 44 is provided with a spring washer 45, which can reduce the possibility of the first locking bolt 43 loosening during the vibration of the machine 11.

[0031] See Figure 5The side clamp 15 includes a clamping seat 51 and a pressure rod 52. The clamping seat 51 has an L-shaped cross-section, and its bottom is detachably connected to the positioning plate 12 by two sets of second locking members 53. The positioning plate 12 has several sets of T-shaped sliding grooves 54 at equal intervals. The distance between two adjacent parallel sets of T-shaped sliding grooves 54 is the same as the distance between two sets of second locking members 53. The pressure rod 52 is threaded to the side of the clamping seat 51, and its end is slidably provided with a lever 55 to drive its rotation. In this embodiment, all four sides of the mold need to be fixed by at least one set of side clamps 15. Two or more sets of side clamps 15 can be selected according to the length and width dimensions of the mold. In actual operation, the operator can first loosen the second locking member 53 according to the width of the side of the square mold 13, slide the clamp 51 along the T-shaped slide groove 54 to a suitable position, so that the side of the positioning plate 12 is in close contact with the side of the mold, and then fix the clamp 51 by the second locking member 53. Finally, drive the pressure rod 52 to rotate by the lever 55, so that the end of the pressure rod 52 presses against the side of the mold after it is pushed forward, so as to achieve horizontal clamping of the four sides of the mold. In this embodiment, the second locking member 53 includes a second locking bolt 56 and a locking nut 57. The T-shaped slide groove 54 is slidably adapted to the head of the second locking bolt 56. The locking nut 57 is set on the bottom of the clamp 51 and is threadedly connected to the second locking bolt 56. By screwing the locking nut 57, the end face of the head of the second locking bolt 56 is pressed against the T-shaped slide groove 54 to achieve locking.

[0032] See Figure 6 - Figure 8 The positioning plate 12 adopts a square design. The T-shaped slides 54 are arranged perpendicular to the four sets of side directions of the positioning plate 12 and end at the diagonal 61 of the positioning plate 12. At the same time, the T-shaped slides 54 on two adjacent sets of side sides combine at the diagonal 61 to form a right angle 62, so that the side clamps 15 can move towards the center of the positioning plate 12 along the T-shaped slides 54. Moreover, they can be arranged on appropriate adjacent sets of T-shaped slides 54 according to the length and width of the mold, and the layout and combination of the clamps can be adjusted to meet diverse production and experimental testing needs. In addition, in this embodiment, the positioning plate 12 has countersunk holes 63 at equal intervals along its diagonal 61, and the fastening bolts 64 used to connect and fix the positioning plate 12 to the machine base 11 are set in the countersunk holes 63.
