[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: an industrial robot welding table, including a workbench 1, a manipulator 2 is fixedly connected to the top of the outer wall of the workbench 1, the manipulator 2 is a prior art, a welding gun is arranged on its surface, and the manipulator 2 is controlled by an electric control unit to perform precision welding on workpieces, etc., a fixing assembly 3 is arranged on the inner wall of the workbench 1, the fixing assembly 3 includes a fixing seat 31, and the fixing seat 31 is arranged in two groups, and the two groups of fixing seats 31 are fixedly connected. By setting two groups of fixing seats 31, two groups of workpieces can be fixed at the same time. After one group is fixed, the two groups of fixing seats 31 can be directly pushed to be used alternately, so that the workpieces can be switched, and the fixing seat 31 is slidably connected to the inner wall of the workbench 1.

[0032] Reference Figure 2-Figure 3 The center of the inner wall of the fixed seat 31 is rotatably connected with a gear 32, and the inner wall of the fixed seat 31 is slidably connected with two sets of upper and lower racks 33, which mesh with the gear 32. When the gear 32 rotates, it will drive the upper and lower sets of racks 33 to move toward each other, thereby driving the two sets of clamping blocks 34 to move synchronously, so as to clamp and fix the workpiece. The bottom end of the outer wall of the clamping block 34 is fixedly connected to the outer wall of the rack 33. When the rack 33 moves, it will drive the clamping block 34 to move synchronously. The inner wall of the fixed seat 31 is slidably connected with two sets of clamping blocks 34, and the inner wall of the right clamping block 34 is elastically connected with an insert block 36 through a limit spring 35, and one end of the limit spring 35 is fixed The top of the outer wall of the plug block 36 is connected, and the other end of the limit spring 35 is fixedly connected to the top of the inner wall of the clamping block 34. The limit spring 35 can automatically reset the position of the plug block 36 when it is pulled upward. The plug block 36 passes through and is slidably connected to the inner wall of the top of the clamping block 34. The surface of the fixed seat 31 is provided with multiple groups of through holes, and the bottom end of the outer wall of the plug block 36 is plugged into the inner wall of the through hole. The plugging between the two fixes the clamping block 34 at multiple positions on the surface of the fixed seat 31, so as to be adjusted according to the size of the workpiece. The outer side wall of the plug block 36 is fixedly connected with a handle 37, and the outer side wall of the fixed seat 31 is provided with a positioning component 4.

[0033] Reference Figure 1 and Figure 4The positioning assembly 4 includes a fixed block 41, and the top of the inner wall of the fixed block 41 is elastically connected to a triangular block 43 through a return spring 42. One end of the return spring 42 is fixedly connected to the top of the inner wall of the fixed block 41, and the other end of the return spring 42 is fixedly connected to the top of the outer wall of the triangular block 43. The function of the return spring 42 is that the triangular block 43 can be automatically reset when it is squeezed and moved. The triangular block 43 is slidably connected to the inner wall of the fixed block 41, and the inner wall of the workbench 1 is provided with a plurality of groups of card grooves. The triangular block 43 contacts the inner wall of the card groove. The contact between the two prevents the fixed seat 31 from moving without being affected by external force. The fixed block 41 is slidably connected to the inner side wall of the workbench 1. The inner side wall of the workbench 1 is provided with a guide groove that fits the movement of the fixed block 41, so that the fixed block 41 can only move laterally along the inner wall of the guide groove.

[0034] Working principle: When the workpiece is welded by the robot 2, the two groups of workpieces to be processed can be placed on the surfaces of the two groups of fixed seats 31. At this time, the handle 37 of the clamping block 34 can be grasped and the handle 37 can be pulled upward to drive the plug block 36 to move upward on the inner wall of the clamping block 34, and the limit spring 35 can be elastically compressed. At this time, the current clamping block 34 can be directly pushed to move on the inner wall of the fixed seat 31. When moving, it will drive the rack 33 to move synchronously on its inner wall, thereby meshing with the gear 32, and during the movement, it will drive the gear 32 to rotate, so that Another set of racks 33 meshing at the upper end of the gear 32 drives the corresponding clamping block 34 to move, so that the two sets of clamping blocks 34 move toward each other to clamp and fix the workpiece. At this time, the handle 37 can be loosened, and the plug block 36 will be elastically acted upon by the limit spring 35 to restore it to its original position to penetrate the clamping block 34 and connect with the through hole at the current position of the top of the fixing seat 31, thereby fixing the position of the clamping block 34. At this time, since the gear 32 is fixed by the rack 33 corresponding to the current clamping block 34, the other set of racks 33 will not move, and the other set of fixing seats 31 are fixed in the same way.

[0035] After the two groups of workpieces are fixed, they can be processed and welded by the manipulator 2. After the workpiece on the surface of the current fixing seat 31 is completed, the fixing seat 31 can be directly pushed to move on the inner wall of the workbench 1. At this time, the inclined surface of the triangular block 43 inside the fixing block 41 on its surface will be out of the slot at the current position of the workbench 1 and squeezed by its inner wall, allowing it to move upward on the inner wall of the fixing block 41 until it reaches the next group of slots, where it will be elastically acted upon by the reset spring 42 to restore it to its initial position, thereby engaging with the slot at the current position of the workbench 1 to fix the fixing seat 31. At this time, the other group of workpieces that have not been welded will be pushed to the bottom end of the manipulator 2 on the surface of the other group of fixing seats 31 for welding. At the same time, the workpiece after welding will move to the left, and the welded workpiece will be out of the processing range of the manipulator 2 as the corresponding fixing seat 31 moves. At this time, the workpiece on its surface can be disassembled, thereby improving work efficiency.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
