Technical Field
[0001] This utility model relates to a sawing fixture for beveling welded steel plates, belonging to the technical field of sawing processing tools. Background Technology
[0002] When welding materials thicker than 5mm, beveling is generally required to ensure full penetration. Currently, the common beveling methods are flame cutting and machining. Flame cutting often causes overheating at the cutting location, severely affecting the quality of the weld joint. For high-strength steel or wear-resistant steel, milling and planing are difficult, and tool wear is severe during beveling. A saw is a common machine tool for cutting steel. It uses high-strength alloy steel saw blades to cut steel, offering convenient processing at a low cost. If beveling could be done on high-strength steel and other special steel plates, it would greatly improve the quality of the beveling, shorten processing time, increase efficiency, and reduce costs. However, there are currently no suitable fixtures for beveling steel plates on saws, which urgently needs to be addressed. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a sawing fixture for processing weld bevels on steel plates. This sawing fixture can clamp the welded steel plate, and the steel plate can be processed by the sawing machine to ensure the quality of the weld bevel, improve processing efficiency, and reduce processing costs.
[0004] The technical solution to the above technical problem is: A sawing machine clamp for processing weld bevels on steel plates includes a sawing machine workpiece base, a workpiece clamping plate, and a clamping plate sliding seat. The sawing machine workpiece base is located below the saw blade, and the workpiece clamping plate and clamping plate sliding seat are mounted on the sawing machine workpiece base. The improvement is that it also includes a steel plate clamp, which includes a telescopic guide rail, end plates, a steel plate support plate, and stops. The telescopic guide rail is placed on the upper surface of the sawing machine workpiece base, and its length direction is parallel to the saw blade's movement direction. The two ends of the telescopic guide rail are respectively connected to the end plates, and the two end plates are respectively tightly connected to the inner sides of the workpiece clamping plates at both ends of the sawing machine workpiece base. The steel plate support plate is a right-angled triangular steel plate. One right-angled side of each of the two steel plate support plates is fixedly connected to the telescopic guide rail. The other right-angled side of each steel plate support plate is located in the vertical direction. The surfaces of the two steel plate support plates are perpendicular to the length direction of the telescopic guide rail. The horizontal inclination angle of the inclined sides of the two steel plate support plates matches the angle of the steel plate bevel. There are vertically downward notches on the inclined sides of the two steel plate support plates, which are opposite to the saw blade of the sawing machine. Two stops are fixed at the lower ends of the two steel plate support plates. The steel plate is placed on top of the two steel plate support plates. The inclined sides of the two steel plate support plates support the two ends of the lower surface of the steel plate. The lower end of the steel plate rests on the two stops.
[0005] The aforementioned sawing fixture for processing welded bevels on steel plates comprises a workpiece base consisting of two tracks with L-shaped cross-sections, placed parallel to each other with their inner L-shaped sides facing each other. A telescopic guide rail is placed on the inner L-shaped sides of the two tracks. The workpiece clamp consists of two vertical steel plates with their surfaces perpendicular to the length direction of the workpiece base. A vertical groove is located at the center of each workpiece clamp, facing the saw blade. The clamp sliding seat consists of a base plate and two inclined plates. The base plate is rectangular and placed between the inner L-shaped sides of the two tracks of the workpiece base. The two inclined plates are vertically welded to the base plate, with a gap between them corresponding to the groove at the center of the workpiece clamp. The front ends of the base plate and the inclined plates are welded to the rear surfaces of the workpiece clamp. The bottom surfaces of the workpiece clamp and the clamp sliding seat are in sliding fit with the inner L-shaped surfaces of the tracks of the workpiece base.

The support base plate and cross connecting plates are both elongated steel plates, with the support base plate being longer than the cross connecting plates. One end of the support base plate has a round shaft hole, and the other end has a long round shaft hole. The cross connecting plates have round shaft holes at both ends and in the middle. The round shaft holes in the middle of two cross connecting plates are rotatably connected by pins to form a group. The round shaft holes at both ends of four groups of cross connecting plates are sequentially connected by pins. The two round shaft holes on the outer sides of the two groups of cross connecting plates at both ends are rotatably connected to the end plates at both ends by pins. The two round shaft holes on the inner sides of the two groups of cross connecting plates at both ends are rotatably connected to the round shaft holes and long round shaft holes of the two support base plates by pins. The upper surfaces of the two support base plates are perpendicularly welded to the right-angled edges of the lower parts of the two steel plate support plates.
[0007] The aforementioned sawing fixture for processing welded bevels on steel plates has an end plate consisting of a T-shaped structure made up of a straight plate and a horizontal plate. The straight plate and the horizontal plate are rectangular strips, and their length directions are perpendicular to the length direction of the sawing workpiece base. The surface of the straight plate is placed vertically, and one side of the horizontal plate is vertically welded to the central axis of the straight plate. One end of the horizontal plate has a round shaft hole, and the other end has an elongated round shaft hole.

The outer sides of the straight plates of the two end plates are respectively tightly connected to the inner sides of the workpiece clamping plates at both ends of the sawing workpiece base.
[0008] The aforementioned sawing fixture for processing welded bevels on steel plates comprises a stop block consisting of an upper top block and lower clamping plates. The upper top block is a cuboid, and the lower clamping plates are rectangular plates. The two lower clamping plates are parallel and opposite to each other, with one end of each lower clamping plate vertically welded to the lower end of the upper top block. The upper top block and the lower clamping plates form an L-shaped structure. The gap between the two lower clamping plates matches the thickness of the steel plate support plate. The two lower clamping plates are clamped above the lower end of the steel plate support plate. Each of the two lower clamping plates has two opposing positioning holes on its surface. The two positioning blocks are arranged sequentially along the length of the lower clamping plates. The steel plate support plate has two round holes on its surface that correspond to the positioning holes of the lower clamping plates. Fixing bolts pass through the fixing holes and the round holes to fix the two lower clamping plates of the stop block to the surface of the steel plate support plate.
