Description

Technical Field

[0001] The utility model relates to the field of brick making machines, in particular to a lifting rod clamping device of a brick making machine. Background Art

[0002] A brick-making machine generally refers to a device that injects concrete slurry into a mold to form bricks. The mold is typically mounted on a liftable rod using a clamping device. After the brick is formed, the mold can be moved upward to facilitate demolding. During the production process, because the lift rod is a bare rod, the connection between the clamping device and the lift rod often deviates. This causes relative displacement between the mold and the lift rod, reducing the accuracy of the brick-making machine and the quality of the final product.

[0003] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0004] The main purpose of the utility model is to provide a brick machine lifting rod clamping device, which has the advantages of firm connection and good stability.

[0005] In order to achieve the above objectives, the solution of the present invention is:

[0006] A brick machine lifting rod clamping device, which includes a base, an upper pressure sleeve, an upper pressure ring, a lower pressure sleeve, a lower pressure ring and a lifting rod; the lifting rod can be lifted and installed on the brick machine; the upper pressure ring and the lower pressure ring are respectively sleeved on the outer wall of the lifting rod in sequence; the upper pressure sleeve is sleeved on the outer wall of the upper pressure ring, and the lower pressure ring is sleeved on the outer wall of the lower pressure ring; the inner wall of the upper pressure sleeve is formed with a first conical surface with a diameter gradually increasing from top to bottom, the outer wall of the upper pressure ring is formed with a second conical surface with a diameter gradually increasing from top to bottom; the inner wall of the lower pressure sleeve is formed with a third conical surface with a diameter gradually decreasing from top to bottom, and the outer wall of the lower pressure ring is formed with a fourth conical surface with a diameter gradually decreasing from top to bottom; the first conical surface and the second conical surface are butted against each other, and the third conical surface and the fourth conical surface are butted against each other; the upper pressure sleeve and the lower pressure sleeve are clamped and fixed; the base is fixedly connected to the upper pressure sleeve or the lower pressure sleeve.

[0007] Furthermore, the upper pressing sleeve and the lower pressing sleeve are fixedly connected by bolts.

[0008] Furthermore, the base is fixedly connected to the lower pressure sleeve.

[0009] Furthermore, a plurality of elastic notches are formed on the upper pressure ring and the lower pressure ring.

[0010] Furthermore, the elastic notches are arranged in a staggered manner.

[0011] Furthermore, a clamping claw for clamping the mold is installed on the base, the middle of the clamping claw is hinged to the base, an abutting airbag is installed between one end of the clamping claw and the base, and the other end of the clamping claw clamps the mold.

[0012] Furthermore, an upper clamping groove and a lower clamping groove are formed on the lifting rod, an upper clamping platform is formed on the inner wall of the upper pressure ring, and a lower clamping platform is formed on the inner wall of the lower pressure ring. The upper clamping platform is clamped in the upper clamping groove, and the lower clamping platform is clamped in the lower clamping groove.

[0013] After adopting the above structure, the brick machine lifting rod clamping device of the utility model has at least the following beneficial effects:

[0014] 1. When the upper pressing sleeve and the lower pressing sleeve are clamped and fixed, the upper pressing ring and the lower pressing ring will shrink toward the central axis due to the abutment of the conical surface, thereby tightening and fixing the lifting rod, so that the lifting rod is more firmly connected.

[0015] Second, when the lifting rod tends to slide upward, the first and second conical surfaces abut against each other, causing the upper pressure ring to further contract and grip the lifting rod. Similarly, when the lifting rod tends to slide downward, the lower pressure ring also contracts and grips the lifting rod, further enhancing the stability of the lifting rod connection.

[0016] 3. The elastic notch can make it easier for the upper pressure ring and the lower pressure ring to contract and hold the lifting rod tightly.

[0017] Compared with the prior art, the utility model can firmly connect the mold to the lifting rod through a brick machine lifting rod clamping device, thereby greatly improving the stability of the connection between the mold and the lifting rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0029] like Figures 1 to 4 As shown, it is a clamping device for a brick machine 1000 lifting rod 6 involved in the utility model, comprising a base 1, an upper pressure sleeve 2, an upper pressure ring 3, a lower pressure sleeve 4, a lower pressure ring 5 and a lifting rod 6; the lifting rod 6 can be lifted and installed on the brick machine 1000; the upper pressure ring 3 and the lower pressure ring 5 are respectively and sequentially sleeved on the outer wall of the lifting rod 6; the upper pressure sleeve 2 is sleeved on the outer wall of the upper pressure ring 3, and the lower pressure ring 5 is sleeved on the outer wall of the lower pressure ring 5; the inner wall of the upper pressure sleeve 2 is formed with a first cone having a diameter gradually increasing from top to bottom The upper pressure ring 3 has a second conical surface 31 with a diameter gradually increasing from top to bottom, and the lower pressure sleeve 4 has a third conical surface 41 with a diameter gradually decreasing from top to bottom. The lower pressure ring 5 has a fourth conical surface 51 with a diameter gradually decreasing from top to bottom. The first conical surface 21 and the second conical surface 31 abut against each other, and the third conical surface 41 and the fourth conical surface 51 abut against each other. The upper pressure sleeve 2 and the lower pressure sleeve 4 are clamped and fixed. The base 1 is fixedly connected to the upper pressure sleeve 2 or the lower pressure sleeve 4. When the upper pressure sleeve 2 and the lower pressure sleeve 4 are clamped and fixed, due to the abutment of the conical surfaces, the upper pressure ring 3 and the lower pressure ring 5 will shrink toward the central axis, thereby tightening and fixing the lifting rod 6, so that the lifting rod 6 is more firmly connected. In addition, when the lifting rod 6 has a tendency to slide upward, the first conical surface 21 and the second conical surface 31 abut against each other, so that the upper pressure ring 3 further shrinks and hugs the lifting rod 6. Similarly, when the lifting rod 6 has a tendency to slide downward, the lower pressure ring 5 will also shrink and hold the lifting rod 6 tightly. This further improves the stability of the connection of the lifting rod 6.

[0030] Preferably, the upper pressure sleeve 2 and the lower pressure sleeve 4 are fixedly connected by bolts 7. As the bolts 7 are tightened, the first conical surface 21 and the second conical surface 31 abut against each other, and the third conical surface 41 and the fourth conical surface 51 abut against each other, and the upper pressure ring 3 and the lower pressure ring 5 deform to tightly embrace the lifting rod 6. Preferably, the base 1 is fixedly connected to the lower pressure sleeve 4.

[0031] Preferably, if Figure 4 As shown, a plurality of elastic notches 8 are formed on the upper pressure ring 3 and the lower pressure ring 5. The elastic notches 8 facilitate the upper pressure ring 3 and the lower pressure ring 5 to contract and hold the lifting rod 6. Preferably, the elastic notches 8 are arranged in a staggered manner.

[0032] Preferably, a clamping claw 11 for clamping the mold 1001 is installed on the base 1. The middle of the clamping claw 11 is hinged on the base 1. A resisting airbag 12 is installed between one end of the clamping claw 11 and the base 1. The other end of the clamping claw 11 clamps the mold 1001. When the resisting airbag 12 is inflated, it pries the clamping claw 11, causing it to clamp the mold 1001.

[0033] Preferably, if Figure 3 As shown, the lifting rod 6 is formed with an upper clamping groove 61 and a lower clamping groove 62, the inner wall of the upper pressure ring 3 is formed with an upper clamping platform 32, and the inner wall of the lower pressure ring 5 is formed with a lower clamping platform 52. The upper clamping platform 32 is clamped to the upper clamping groove 61, and the lower clamping platform 52 is clamped to the lower clamping groove 62. This allows the upper pressure ring 3 and the lower pressure ring 5 to be more firmly connected to the lifting rod 6.

[0034] Compared with the prior art, the present invention can firmly connect the mold 1001 to the lifting rod 6 through a clamping device of the brick machine 1000 lifting rod 6, thereby greatly improving the stability of the connection between the mold 1001 and the lifting rod 6.

[0035] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
