Machining welding equipment

Abstract

The invention discloses machining welding equipment which comprises a welding table, a welding frame, a welding assembly, a clamping assembly, a switching assembly and a grinding part. The welding frame is fixed to the welding table and used for installing the welding assembly, the switching assembly and the grinding assembly, and when the clamping assembly induces that the borne pressure is too large, a signal is sent out to enable the switching assembly to move, so that the welding assembly is prevented from welding a workpiece, and the situation that the clamping pressure of the workpiece is too large is reminded. By means of the clamping assembly, when the sensing parts clamp a workpiece through mutual approaching sliding, if the pressure exceeds a set threshold value, the sensing parts immediately send signals to the switching assembly, the signals can be sent to the switching assembly, an elastic part moves to form blocking, and therefore a welding part cannot slide downwards; therefore, workpiece deformation or equipment damage caused by too large clamping pressure is avoided, then the sensing parts are driven to slowly get away from each other through the rotation action generated by the fine adjustment part, and fine adjustment of the clamping pressure is achieved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, and particularly relates to a mechanical processing and welding device. BACKGROUND

[0002] Mechanical processing is a manufacturing process of changing the shape, size and performance of a workpiece by using mechanical equipment. Welding, as a key link of mechanical processing, is widely used in the fields of automobile manufacturing, aerospace, building steel structure and the like.

[0003] The mechanical processing and welding device disclosed in the patent with the patent number CN109732262B can reduce the collision force when the clamping seat contacts with the mechanical material by compressing the compression spring, moving the buffer seat, moving the pressure rod under the action of the connecting rod, moving the horizontal plate, compressing the buffer spring and the elastic deformation of the compression spring and the buffer spring.

[0004] However, in actual use, when clamping, if the clamping force exceeds the bearing capacity of the workpiece, the excessive clamping force will cause plastic deformation of the surface of the workpiece and form dents. These dents not only affect the appearance quality of the workpiece, but also form stress concentration points when the workpiece is stressed, thereby reducing the structural strength and service life of the workpiece.

[0005] Therefore, the present application provides a mechanical processing and welding device. SUMMARY

[0006] The present application aims to solve the problems in the prior art and provides a mechanical processing and welding device.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0008] The mechanical processing and welding device comprises a welding table, a welding frame, a welding assembly, a clamping assembly, a switching assembly and a polishing part.

[0009] The welding frame is fixed on the welding table and is used for mounting the welding assembly, the switching assembly and the polishing assembly. When the clamping assembly senses that the bearing pressure is too large, a signal is sent to cause the switching assembly to displace, so as to prevent the welding assembly from welding the workpiece, thereby reminding that the clamping pressure of the workpiece is too large.

[0010] The switching assembly can drive the welding assembly to slide upward, drive the welding assembly to rotate, switch the welding tool, and drive the welding assembly to slide downward without rotating, so that the welding assembly can weld a new workpiece with the switched welding tool, and the cycle can avoid affecting the service life of a welding tool due to continuous use of the welding tool.

[0011] Preferably, the welding assembly is composed of a mounting part and a welding part, the mounting part is used for mounting the welding part, and the welding part can slide by rotating, so that the welding part can slide above the workpiece to facilitate welding of the workpiece; and the welding part can weld the workpiece by generating instantaneous high temperature.

[0012] Preferably, the switching assembly is composed of a sliding rotation part and an elastic part, the sliding rotation part drives the welding part to rotate under the action of the elastic part by sliding upward, so as to complete switching between welding tools; and the elastic part can make the sliding rotation part drive the welding part to stably slide downward by sliding when the sliding rotation part drives the welding part to slide downward, so that the switched welding tool can weld a new workpiece.

[0013] Preferably, the clamping assembly is composed of a fine adjustment part and a sensing part, the sensing part can clamp the workpiece by sliding close to each other, can send a signal to the switching assembly when the clamping pressure is too large, so that the elastic part is displaced to form an obstacle, so that the welding part cannot slide downward, and the fine adjustment part can make the sensing part slowly move away from each other by rotating, so as to reduce the clamping pressure on the workpiece.

[0014] Preferably, the polishing part can generate continuous friction with the welding part by high-speed rotation after the switching assembly drives the welding assembly to slide upward, so as to clean the accumulated substances such as welding slag on the surface of the welding part.

[0015] Preferably, four first telescopic rods are arranged between the clamping assembly and the welding table, and the telescopic motion of the first telescopic rods can control the height of the clamping assembly, so that workpieces of different heights can be in contact with the welding part.

[0016] Preferably, the welding frame is fixed on the welding table and is used for mounting the welding assembly, the switching assembly and the polishing assembly, the elastic part is arranged in the mounting part, and the sensing part is arranged on the fine adjustment part.

[0017] Preferably, the sliding rotation part can drive the welding part to slide upward to the polishing part, and the switching assembly works before and after each welding.

[0018] The present application has the following beneficial effects:

[0019] When the sensing part is clamped to the workpiece by sliding towards each other, if the pressure exceeds the set threshold, the sensing part immediately sends a signal to the switching assembly, which can send a signal to the switching assembly to displace the elastic part to form a barrier, so that the welding part cannot slide down, thereby avoiding deformation of the workpiece or damage to the equipment caused by excessive clamping pressure. Subsequently, the fine adjustment part generates a rotating action to drive the sensing part to slowly move away from each other, thereby achieving fine adjustment of the clamping pressure.

[0020] When the welding part completes welding, the sliding rotating part drives the welding part to rotate by upward sliding action, thereby completing the switching between the welding tools. When welding is needed again, the elastic part can drive the sliding rotating part to stably lower the welding part by sliding action when the sliding rotating part drives the welding part to slide down, thereby enabling the switched welding tool to weld a new workpiece. This continuous cycle enables multiple welding tools to work alternately, avoiding the intensification of high-temperature wear caused by continuous use of a single welding tool, thereby affecting the service life.

[0021] When the sliding rotating part drives the welding part that has completed welding to slide upwards, the welding tool that has just completed welding is located at the polishing part. The polishing part generates continuous friction with the welding part by high-speed rotating action. Under the action of friction, the accumulated substances such as welding slag and oxides are removed by grinding, thereby avoiding the influence of accumulated substances such as welding slag on the subsequent welding quality of the welding part.
