Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a polishing and grinding equipment for steel structure combined parts. Background Art

[0002] Steel structure refers to a steel structure composite component that can bear and transfer loads and is connected by connecting parts such as steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels, cold-bent or welded. Since the steel structure composite parts need to be fixed by a clamping mechanism before polishing and grinding, the diameter inside the clamping mechanism is usually fixed. When the diameter of the steel structure composite part is smaller than the internal diameter of the clamping mechanism, the clamping is not firm. Therefore, the device can only clamp a steel structure composite part whose diameter just fits the inner wall of the clamping mechanism of the device. In addition, since the clamping mechanism is usually composed of two clamping parts, a limiting structure should be set between the two clamping parts to prevent the two clamping parts from being misaligned during the clamping process, which in turn causes the clamping parts to crack. The polishing and grinding equipment for steel structure composite parts in the prior art does not have the function of adjusting the internal diameter of the steel structure composite parts and preventing cracking.

[0003] It is known that a round tube end grinding and polishing device for steel structure is disclosed (publication number CN215968092U). The round tube end grinding and polishing device for steel structure rotates a bidirectional screw, and the rotation of the bidirectional screw drives the screwed sliders to approach each other. The two sliders respectively drive the two clamping plates to approach each other to clamp and fix the round tube, ensuring that the round tube will not deviate during the grinding and polishing process, which is beneficial to improving the quality of grinding and polishing of the round tube end by the grinding mechanism. However, although the above technical scheme can play a good role in improving the polishing quality of steel structure assembly parts.

[0004] At present, since steel structure assembly parts need to be fixed by a clamping mechanism before polishing and grinding, the diameter inside the clamping mechanism is usually fixed. When the diameter of the steel structure assembly parts is smaller than the internal diameter of the clamping mechanism, the clamping becomes loose. Therefore, the device can only clamp a steel structure assembly part whose diameter just fits the inner wall of the clamping mechanism of the device. The device is not provided with a related structure for adjusting the size of the internal diameter of the clamping mechanism, which leads to poor practical effect. In addition, since the clamping mechanism is usually composed of two clamping parts, a limiting structure should be provided between the two clamping parts to prevent the two clamping parts from being misaligned during the clamping process, which leads to cracking of the clamping parts. The device is not provided with a related limiting structure for the two clamping parts, which leads to cracking of the clamping parts and increases the cost of polishing and grinding. For this reason, we provide a polishing and grinding equipment for steel structure assembly parts. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a polishing and grinding device for steel structure combination parts, which solves the problem that the device does not have a relevant structure for adjusting the internal diameter of the clamping mechanism, resulting in poor practical effect, and the device does not have a relevant structure for limiting the two clamping parts, resulting in cracking of the clamping parts and increasing the grinding and polishing costs.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a polishing and grinding equipment for steel structure combination parts, multiple fixed splints, multiple reset springs are symmetrically arranged on the opposite sides inside the multiple fixed splints, multiple movable splints are symmetrically distributed on one side of the multiple reset springs, the diameter of the multiple movable splints is smaller than the diameter of the multiple fixed splints, and placement grooves are opened inside the multiple movable splints, the lower ends of the multiple fixed splints are fixedly connected to the movable plate, the lower end of the movable plate is fixedly connected with a slider, and a limiting groove is opened on one side of the front end of the movable plate, and the other side of the front end of the movable plate is fixedly connected to a limiting block.

[0007] Preferably, a threaded hole is provided inside the slider, and the slider is threadedly connected to the bidirectional lead screw through the threaded hole, and one side of the bidirectional lead screw is fixedly connected to the output end of the motor B.

[0008] Preferably, the lower end of the motor B is fixedly connected to the base through the base B, and a plurality of movable grooves are symmetrically provided on two opposite sides of the upper end of the base, and one side of the upper ends of the plurality of movable grooves is movably connected to the movable plate.

[0009] Preferably, hydraulic cylinders are symmetrically provided on opposite sides of the base, a hydraulic rod is provided on one side of the hydraulic cylinder, a central box is provided on one side of the hydraulic rod, a material receiving trough is provided inside the central box, the upper end of the material receiving trough is in an open and closed state, and the upper end of the central box is connected to the bottom of the grinding box.

[0010] Preferably, a machine base A is provided in the middle of one side of the grinding box, and a socket slot is opened in the middle of the other side of the grinding box. The interior of the machine base A is fixedly connected with the motor A, and the output end of the motor A is fixedly connected with the rotating rod through a bearing seat. A grinding disc is provided on one side of the rotating rod.

[0011] The working principle and beneficial effects of the utility model are:

[0012] 1. The utility model places the steel structure assembly parts to be polished inside the placement groove through the placement groove. When the diameter of the steel structure assembly parts is smaller than the inner diameter of the fixed splint and larger than the inner diameter of the placement groove, the two movable splints are spread apart. The two movable splints squeeze the multiple uniformly distributed return springs behind them while being spread apart. The multiple uniformly distributed return springs begin to shrink while being squeezed by the two movable splints. The multiple uniformly distributed return springs gradually increase the inner diameter of the placement groove during the shrinkage process until the inner diameter of the placement groove is the same as the diameter of the steel structure assembly parts to be polished, and the two movable splints lose the force to spread apart. When the two movable splints lose the force to spread apart, the multiple uniformly distributed return springs stop shrinking, thereby achieving a better practical effect.

[0013] 2. The utility model uses two fixed splints to clamp, and two movable plates are respectively provided at the bottom of the two fixed splints, and two limit blocks and limit grooves are cross-distributed inside the two movable plates. During the clamping process of the two fixed splints, the limit block of one of the fixed splints is inserted into the limit groove of the other fixed splint, and the limit groove of one of the fixed splints is inserted into the limit block of the other fixed splint. The setting of the limit blocks and limit grooves of the two fixed splints can effectively prevent the two fixed splints from being misaligned and cracked, thereby reducing the cost of grinding and polishing.

The setting of the base 23 plays a good supporting role. A plurality of movable grooves 7 are symmetrically provided on the opposite sides of the upper end of the base 23, and one side of the upper ends of the plurality of movable grooves 7 is movably connected with the movable plate 17. The setting of the movable groove 7 plays a role in the horizontal movement of the slider 19.

The hydraulic rod A concentrating box 5 is provided on one side of 10, and a material receiving trough 4 is provided inside the concentrating box 5. The upper end of the material receiving trough 4 is in an open and closed state. The upper end of the concentrating box 5 is connected with the bottom of the grinding box body 2. The upper end of the concentrating box 5 is connected with the bottom of the grinding box body 2, so that the debris generated by grinding and polishing can directly fall into the material receiving trough 4 inside the concentrating box 5, thereby playing a good collection role.

[0026] When in use, first start the motor B22 to drive the bidirectional screw rod 20 to rotate inside the movable groove 7. The bidirectional screw rod 20 drives the two sliders 19 to move relative to each other while rotating. The two sliders 19 move relative to each other while driving the two movable plates 17 to move relative to each other. When the two movable plates 17 move relative to each other, two movable plates 17 are respectively provided at the bottom of the two fixed splints 14. Two limit blocks 18 and limit grooves 16 are cross-distributed inside the two movable plates 17. During the clamping process of the two fixed splints 14, the limit block 18 of one of the fixed splints 14 is inserted into the limit block 18 of the other fixed splint 14.

When the steel structure assembly parts When the diameter is smaller than the inner diameter of the fixed clamping plate 14 and larger than the inner diameter of the placement groove 21, the two movable clamping plates 15 are stretched apart. When the two movable clamping plates 15 are stretched apart, the multiple evenly distributed return springs 13 are squeezed behind.
