Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a downward flipping fixture for automated welding equipment. Background Technology

[0002] The main function of the fixtures in welding equipment is to fix and position the workpiece. Through precise fixing and positioning, the fixtures ensure accuracy and stability during the welding process, thereby improving processing quality and efficiency.

[0003] Traditional fixtures have limited functionality. When welding requires processing different parts of a workpiece, operators must first remove the workpiece from the fixture, readjust its position, and then clamp it back into the fixture, which reduces production efficiency. Therefore, it is necessary to develop a downward flipping fixture for automated welding equipment. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

Connecting rods are symmetrically hinged to the upper end of the lifting frame.

[0008] Mounting brackets are hingedly provided at the other ends of the two connecting rods respectively. The left and right side walls of the two mounting brackets are slidably penetrated by the rod bodies of the fixing rods. An inverted "L"-shaped mounting groove is opened in the inner cavity of the mounting bracket.

[0025] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1-5 , which shows a structural schematic diagram of an embodiment of the lower flipping fixture of an automated welding device of the present utility model. Please refer to Figures 1-5 , and a detailed introduction will be given to the lower flipping fixture of an automated welding device.

[0027] A lower flipping fixture of an automated welding device includes a base 100. A fixed table 102 is fixedly arranged on the top of the base 100 through legs 101. Vertically arranged brackets 103 are symmetrically and fixedly arranged on both sides of the bottom of the fixed table 102. A horizontally arranged fixed rod 104 is fixedly arranged between the two brackets 103. A "U"-shaped lifting frame 105 is arranged in a lifting manner on the top of the base 100 below the fixed rod 104. A fixed frame 107 is fixedly arranged on the top of the base 100. The side cross-section of the fixed frame 107 is in the shape of a "冂". And a vertically arranged electric push rod 108 is fixedly arranged on the top wall of the inner cavity of the fixed frame 107. The bottom of the output rod of the electric push rod 108 is fixed at the center of the surface of the lifting frame 105. Starting the electric push rod 108 can drive the lifting frame 105 to rise or fall. The upper ends of the lifting frame 105 are symmetrically and hingedly arranged with connecting rods 106 on the left and right.

[0028] The other ends of the two connecting rods 106 are respectively hingedly arranged with mounting frames 200. The left and right side walls of the two mounting frames 200 are slidably penetrated by the rod body of the fixed rod 104. Through holes for the fixed rod 104 to penetrate are opened on the side walls of the mounting frames 200. A horizontally arranged linear bearing is fixedly arranged inside the through holes. The linear bearing slides on the outer side of the rod body of the fixed rod 104. The friction between the mounting frame 200 and the rod body of the fixed rod 104 during movement is reduced through the linear bearing.

[0029] The two mounting brackets 200 are symmetric about the base 100 in the left-right direction, and the two mounting brackets 200 are in the shape of a "C" and a mirror-image "C" respectively. The two mounting brackets 200 respectively penetrate through the upper and lower side walls of the fixed platform 102 with a gap and move towards each other. When the lifting frame 105 moves up and down, the two mounting brackets 200 are driven to move towards each other by the connecting rod 106;

[0030] Openings 109 for the transverse movement of the mounting brackets 200 are formed in the upper and lower side walls of the fixed platform 102. The openings 109 are arranged parallel to the fixed rod 104. An inverted "L"-shaped mounting groove 201 is formed in the inner cavity of the mounting bracket 200. A vertical vertical rod 202, a transverse cross rod 203 located above the vertical rod 202 and a transverse driving rod 207 located below the vertical rod 202 are rotatably arranged inside the mounting groove 201. One end of the cross rod 203 rotatably penetrates through the side wall of the mounting bracket 200 and is provided with a clamping plate 204. The two clamping plates 204 are symmetric about the base 100 in the left-right direction. The vertical rod 202 and the cross rod 203 are respectively provided with a first bevel gear 205 and a second bevel gear 206 that mesh with each other. The vertical rod 202 and the driving rod 207 are respectively provided with a third bevel gear 208 and a fourth bevel gear 209 that mesh with each other. A transverse double-headed servo motor 210 is fixedly arranged at the center of the bottom wall of the fixed platform 102. The two output shafts of the double-headed servo motor 210 are fixedly connected with a transverse spline rod 211 through couplings. The rod body of the driving rod 207 rotatably penetrates through the inner side wall of the mounting groove 201 and is fixedly provided with a transverse spline sleeve 212. The other end of the spline sleeve 212 is for the rod body of the spline rod 211 to be inserted for transmission. A support frame 213 for installing the spline sleeve 212 is fixedly arranged on the side wall of the mounting groove 201. The rod body of the spline sleeve 212 rotatably penetrates through the side wall of the support frame 213 through a bearing sleeve. An anti-slip pattern 214 is arranged on the side of the clamping plate 204 away from the cross rod 203, which increases the stability when clamping components.

[0031] In the specific use process, the component to be clamped is placed between the two clamping plates 204. The electric push rod 108 is started to drive the lifting frame 105 to descend, and the two mounting brackets 200 are driven to move towards each other and move towards the component direction through the connecting rod 106, so as to clamp and fix the component through the clamping plates 204. The spline sleeve 212 then slides transversely along the rod body of the spline rod 211. When it is necessary to control the rotation of the component, the double-headed servo motor 210 is started again to drive the two spline rods 211 to rotate, and then the driving rod 207 is driven to rotate through the spline sleeve 212. The vertical rod 202 is driven to rotate through the fourth bevel gear 209 and the third bevel gear 208, and then the cross rod 203 is driven to rotate through the first bevel gear 205 and the second bevel gear 206, so as to drive the two clamping plates 204 and the component to flip, which is convenient for processing.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
