Description

Technical Field

[0001] The invention relates to the technical field of component structural features specially suitable for boring machines or drilling machines, and in particular to a positioning and punching device for steel structure processing. Background Art

[0002] Steel structure engineering is a structure made mainly of steel structure, which is one of the main types of building structures. The characteristics of steel structure are high strength, light weight, good overall rigidity and strong deformation capacity, so it is particularly suitable for building large-span, super-high and super-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. The most critical processes in steel structure manufacturing technology are hole making and welding processes. However, in the process of hole making, the steel structure is fixed on the support plate plane by a clamping assembly. When the drill bit penetrates the steel structure, the drill bit will hit the support plate, causing damage to the support plane and the drill bit. In addition, the existing drill bit positioning method is to move the drill bit to the surface of the steel structure for positioning. When moving the drill bit, misoperation may cause the drill bit to collide with the steel structure. Therefore, a positioning and punching device for steel structure processing is proposed.

[0009] Furthermore, the cooling assembly includes a water tank with an opening at the top, a filter screen is provided in the middle of the water tank, a water pump is provided at the bottom water outlet of the water tank, the water pump is connected to a water spray head through a hose, and the water spray head is fixed to the lower surface of the top plate through a fixing rod.

[0010] Furthermore, the filter screen is arranged at an inclination, and the lower part of the filter screen is far away from the water outlet.

[0011] Furthermore, a pneumatic pressure regulating valve for maintaining a constant flow rate and pressure of the water sprinkler is provided between the hose and the water sprinkler.

[0035] The clamping block 503 is arranged in a Z shape. When the steel structure workpiece is clamped by the clamping block 503, there is a gap between the lower surface of the steel structure workpiece and the L sliding plate 501, which can prevent the drill bit 204 from drilling into the L sliding plate 501 when penetrating the steel structure workpiece.

[0036] Furthermore, the contact surface between the clamping block 503 and the workpiece is provided with anti-slip rubber; In a specific implementation, the friction between the steel structure workpiece and the clamping block 503 is increased by the anti-skid rubber, while preventing the steel structure workpiece from hitting the clamping block 503 .

[0037] For further reference, Figure 8 The cooling assembly 4 includes a water tank 401 with an opening at the top, a filter screen 402 is provided in the middle of the water tank 401, a water pump 403 is provided at the bottom water outlet of the water tank 401, the water pump 403 is connected to a water spray head 406 through a hose 404, and the water spray head 406 is fixed to the lower surface of the top plate 101 through a fixing rod 407; In a specific implementation, during cooling, the water pump 403 guides the cooling water in the water tank 401 to the water spray head 406 through the hose 404, and the water spray head 406 sprays the water to the hole turning position of the drill bit 204 for cooling.

One end of the water bag 410 is connected to the T-shaped tube 408 through the one-way pressure relief valve 409; When cooling and positioning are performed, cooling water is simultaneously transported to the inside of the T-tube 408 through the hose 404, and then transported to the inside of the water bag 410 through the T-tube 408; By setting the water bag 410, the irregular workpiece can be clamped by the deformation of the water bag 410 itself, and the workpiece can be cooled by the cooling water inside the water bag 410; Cooling principle: heat conduction cooling; Among them, one-way pressure relief valves 409 are provided at both ends of the water bag 410. The one-way pressure relief valve 409 is close to the T-tube 408. When the pressure at the T-tube 408 reaches the set value, the cooling water inside the T-tube 408 passes through the one-way pressure relief valve 409 and enters the water bag 410. When the water pressure inside the water bag 410 reaches the pressure set by the other one-way pressure relief valve 409, the other one-way pressure relief valve 409 starts to relieve pressure, so that the cooling water flows vertically into the water tank 410.
