Description

Technical Field

[0001] The utility model relates to the field of brick making machine accessories, in particular to an oil cylinder fixing part. Background Art

[0002] The mold core-pulling cylinder needs to be fixed with a flange. When fixing the cylinder, the fixing position needs to be calculated, and the welding and installation errors are strictly required to ensure that the action is in place under the premise of firm fixing. When the actual installation position error is too large or other situations require the cylinder position to be moved, it is not easy to adjust and disassemble. At the same time, the mold core-pulling cylinder has a high strength requirement for axial fixation. Although the existing portable fixing method is convenient for disassembly and assembly, it will become loose during cylinder operation, causing production accidents. Summary of the invention

[0003] The purpose of this utility model is to solve the above problems and design a cylinder fixing clamp. The specific design scheme is:

[0004] A cylinder fixing clamp comprises a sleeve sleeved on the cylinder body, two clamping rings are sleeved on the sleeve, the outer wall of the sleeve is an inclined surface, and the inner rings of the two clamping rings are against the inclined surface. The fixing principle is that the two clamping rings play a clamping role to fix the cylinder, and the stress between the two clamping rings and the inclined surface further increases the fixing strength of the cylinder in the axial direction. The sleeve can increase the contact surface between the overall fixing clamp and the cylinder, increase its radial fixing strength by increasing static friction, and provide a carrier for the design of the inclined surface.

[0005] The inclined surface is in a "V"-shaped structure. Among the two retaining rings, the inner ring side of one retaining ring presses against one side of the "V"-shaped structure, and the inner ring side of the other retaining ring presses against the other side of the "V"-shaped structure. During the clamping process of the retaining rings, the two retaining rings are continuously compacted through contact with the inclined surface to form two opposite stresses along the axial direction of the cylinder, thereby achieving fixation.

[0006] The clamping ring includes two "C"-shaped structural clamping parts, the two clamping parts are connected by bolts, the oil cylinder is clamped in the middle of the "C"-shaped structures of the two clamping parts, and the clamping parts fix the oil cylinder by tightening the bolts.

[0007] The clamping ring comprises two clamping parts, namely a fixed clamping part and a movable clamping part. The fixed clamping part is fixed on a base beam, and the base beam is a metal beam constituting a frame of a brick making machine.

[0008] Of the two clamping rings, the two clamping parts of one clamping ring are distributed left and right, and the two clamping parts of the other clamping ring are distributed up and down. This structure can better calibrate the axial direction of the cylinder shaft of the oil cylinder during the tightening process of the clamping ring.

[0009] The sleeve is fixedly connected to the cylinder. If the space requirement for radial adjustment of the cylinder is not large, the sleeve can be directly fixed to the cylinder by welding or other means. If the position of the sleeve on the cylinder needs to be adjusted, a sleeve with a radial cross-section of a "C" shape can be used, and the sleeve can be clamped to the outside of the cylinder by bolts, or a reversible fixing method such as an interference fit can be used.

[0010] The oil cylinder fixing clamp obtained by the above technical solution of the utility model has the following beneficial effects:

[0011] That is, the cylinder can be conveniently disassembled and assembled and widely adjusted in the axial direction through the casing, and the radial position of the cylinder can be conveniently fine-tuned through the clamping ring, while ensuring that the cylinder is firmly fixed to avoid loosening of the cylinder during core pulling operation.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] A cylinder fixing clamp comprises a sleeve 2 sleeved on a cylinder body of a cylinder 1, two retaining rings 3 sleeved on the sleeve 2, the outer wall of the sleeve 2 is a slope 4, the inner rings of the two retaining rings 3 abut against the slope 4, and the fixing principle is to achieve the fixing of the cylinder 1 by the two retaining rings 3 playing a clamping role, and further increase the fixing strength of the cylinder 1 in the axial direction by the stress between the two retaining rings 3 and the slope 4, the sleeve 2 can increase the contact surface between the overall fixing clamp and the cylinder 1, increase its radial fixing strength by increasing static friction, and provide a carrier for the design of the slope 4.

[0020] The inclined surface 4 is in a "V"-shaped structure. Among the two snap rings 3, the inner ring side of one snap ring 3 presses against one side of the "V"-shaped structure, and the inner ring side of the other snap ring 3 presses against the other side of the "V"-shaped structure. During the clamping process of the snap rings 3, the two snap rings 3 are continuously compacted by contact with the inclined surface 4 to form two opposite stresses along the axial direction of the cylinder 1, thereby achieving fixation.

[0021] The clamping ring 3 includes two "C"-shaped structural clamps, which are connected by bolts 5. The oil cylinder 1 is clamped between the "C"-shaped structures of the two clamps, and the clamps are fixed to the oil cylinder 1 by tightening the bolts 5.

[0022] The clamping ring 3 includes two clamping parts, namely a fixed clamping part 6 and a movable clamping part 7. The fixed clamping part 6 is fixed on a base beam 8, and the base beam 8 is a metal beam constituting the frame of the brick making machine.

[0023] Of the two snap rings 3 , the two clamping parts of one snap ring 3 are distributed left and right, and the two clamping parts of the other snap ring 3 are distributed up and down. This structure can better calibrate the axial direction of the cylinder shaft of the oil cylinder 1 during the tightening process of the snap ring 3 .

[0024] The sleeve 2 is fixedly connected to the cylinder 1. If the space requirement for radial adjustment of the cylinder is not large, the sleeve 2 can be directly fixed to the cylinder by welding or other means. If the position of the sleeve 2 on the cylinder needs to be adjusted, a sleeve 2 with a "C"-shaped radial cross-section can be used, and the sleeve 2 can be clamped to the outside of the cylinder by bolts, or a reversible fixing method such as an interference fit can be used.

[0025] When equipment is modified, based on the existing equipment, the sleeve 2 is directly fixed to the cylinder body of the oil cylinder 1, and the fixing clamp 7 is fixed to the base beam 8 to complete the equipment modification, and the modification cost is low.

[0026] During installation, the oil cylinder 1 is passed through the through hole on the base beam 8, and then the movable clamp 7 and the fixed clamp 6 are tightened by the bolt 5 to form a clamp ring 3 to complete the installation.

[0027] After installation, the two clamping parts of one clamping ring 3 are distributed left and right, and the two clamping parts of the other clamping ring 3 are distributed up and down, respectively completing the precise calibration of the axial direction of the oil cylinder 1 from the horizontal direction and the vertical direction.

[0028] After installation, since the inner ring of the clamping ring 3 contacts the inclined surface 4, the two clamping rings 3 contact the two sides of the V-shaped structure respectively, forming internal stress. Compared with fixing by static friction alone, the fixing method is more secure.

[0029] When it is necessary to fine-tune the axial direction of the oil cylinder 1, it is achieved by adjusting the inner diameters of the two retaining rings 3, thereby adjusting the fitting position of the retaining rings 3 and the inclined surface 4. When the inner diameter of one retaining ring 3 is enlarged by loosening the bolt 5 and the inner diameter of another retaining ring 3 is reduced by tightening the bolt 5, the oil cylinder 1 will move toward the side of the retaining ring 3 with the reduced inner diameter.

[0030] When the oil cylinder 1 needs to be disassembled, the oil cylinder 1 can be disassembled by simply unscrewing the movable clamp 7 .

[0031] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
