[0001] The present application relates to the technical field of welding material supply equipment, in particular to a material taking and feeding device for welding brake spare parts of electric vehicles. BACKGROUND

[0002] The drum brake of the electric vehicle is generally equipped with a material taking and feeding device with high automation level for taking and feeding the drum brake spare parts during automatic welding processing. However, some drum brake spare parts are in the form of arc-shaped sheets, so the existing material taking and feeding device usually takes and feeds the stacked drum brake spare parts one by one. However, the stacked drum brake spare parts have the following defects: 1. The stacked drum brake spare parts are not regular and stable, and the stress during taking causes misalignment between the lower stacked drum brake spare parts, which affects the accuracy of the taking and feeding process; 2. The contact between the feeding structure and the drum brake spare parts is not regular, and there is a gap between them, which reduces the accuracy of the drum brake spare parts in the welding position. Therefore, the present application provides a material taking and feeding device for welding brake spare parts of electric vehicles. SUMMARY

[0003] The present application provides a material taking and feeding device for welding brake spare parts of electric vehicles.

[0004] The present application achieves the above-mentioned purpose by the following technical scheme.

[0009] Further technical solutions, the pneumatic clamping jaw part further comprises a pneumatic clamp, and two moving ends on the same side of the pneumatic clamp are respectively connected and fixed with two jaw blocks.

[0010] Further technical solutions, the pneumatic clamping jaw part is transferred to the front of the workpiece in-place station through side turning.

[0011] Further technical solutions, the concave surface distributed on the stamping isomorphism surface is opposite to the convex structure part distributed on the side surface of the workpiece body.

[0012] Compared with the prior art, the difference of the present application is that: Difference one: each of the stacking parts is composed of three right-angled triangularly distributed stacking limiting columns and one isomorphism pad block, and the shape specifications of the two ends of the workpiece body and the shape specifications of the outer side of the middle part are respectively matched with three edge part matching grooves in sequence, which can completely match the stacking and placement of the circular arc-shaped workpiece to be processed, can avoid the micro-offset misplacement of the workpiece stacking, and can improve the smoothness of the grabbing and separation.

[0013] Difference two: the pneumatic clamping jaw part is located above the middle part of the circumcircle formed by the right-angled triangle, which improves the vertical positioning accuracy of the pneumatic clamping jaw part moving and grabbing material, is beneficial to the claw material from the gravity center part of the circular arc workpiece, and achieves the effect of balanced grabbing.

[0022] Please refer to Figures 1-5As shown, a kind of material taking and feeding device for welding brake spare parts of electric vehicle, including distribution in carousel 1 on stacking part 2 and pneumatic jaw part 4, each stacking part 2 is made of three right triangle distribution stacking limiting post 220 and one isomorphic pad 210, three stacking limiting post 220 edge respectively different edge matching groove 221 is provided, one isomorphic pad 210 is provided between the bottom of three stacking limiting post 220, and isomorphic pad 210 top surface is set as stamping isomorphic surface 211, pneumatic jaw part 4 is located in the upper part of the middle part of the circle arc formed by right triangle, the bottom contact surface of two jaw blocks 420 in pneumatic jaw part 4 is respectively provided with different single-piece workpiece isomorphic jaw groove 421, the concave surface distribution on stamping isomorphic surface 211 is opposite to the convex structure part distributed on the side of workpiece body 3.

[0023] As shown in Figure 2 and Figure 4 As shown, the stacking part 2 is provided with three, and the workpiece body 3 is stacked in the middle of each stacking part 2, the shape specification of the two ends of the workpiece body 3 and the shape specification of the middle outside are matched with three edge matching grooves 221 in turn, and the surface shape structure of the workpiece body 3 is divided into two parts, one single-piece workpiece isomorphic jaw groove 421 and another single-piece workpiece isomorphic jaw groove 421, by three edge matching grooves 221 and single-piece workpiece isomorphic jaw groove 421 respectively matching the shape of each part of workpiece body 3, the precision of workpiece stacking and matching grabbing can be further improved.

[0024] As shown in Figure 1 and Figure 3 As shown, the carousel 1 is arranged on the platform 10, and the motor module 8 is installed on the top side of the support plate 9 on one side of the platform 10, the output end of the motor module 8 is installed with the swing carrier plate 6, and the middle and one end of the swing carrier plate 6 are respectively installed with the sliding seat 14 and the L-shaped frame 13, the guide rail 7 is slidingly installed on the sliding seat 14, the push-pull cylinder 5 is installed on the L-shaped frame 13, one end of the guide rail 7 and one end of the push-pull cylinder 5 are connected on the same L-shaped block 12, and the L-shaped block 12 is fixedly connected with the pneumatic jaw part 4 on one side.

[0025] As shown in Figure 4 As shown, the pneumatic jaw part 4 further includes pneumatic clamp 410, two moving end portions 411 on the same side of the pneumatic clamp 410 are respectively connected with two jaw blocks 420.

[0026] As shown in Figure 1 As shown, the pneumatic jaw part 4 is transferred to the front of the workpiece in place station 11 by side turning.

[0027] Material handling and loading operation principle: The vertically downward push-pull cylinder 5 extends and pushes the pneumatic gripper 4 connected by the L-shaped block 12 toward the top of the stacking section 2 until the two gripper blocks 420 are placed on both sides of the topmost workpiece body 3. The pneumatic clamp 410 moves the two gripper blocks 420 to move in opposite directions to clamp the workpiece body 3. The push-pull cylinder 5 retracts and moves the clamped workpiece body 3 out of the stacking section 2. The motor module 8 drives the push-pull cylinder 5 connected by the swing carrier plate 6 to rotate to the side, so that the clamped workpiece body 3 is moved to the front of the workpiece positioning station 11. Then the push-pull cylinder 5 extends again to send the workpiece body 3 to the positioning position of the workpiece positioning station 11. The gripper blocks 420 reset, the push-pull cylinder 5 resets, and the material handling and loading process of the workpiece body 3 is completed.

[0028] The difference compared to existing technologies is: Firstly, each of the stacking sections 2 consists of three stacking limiting posts 220 arranged in a right-angled triangle and a similarly shaped pad 210. The shape specifications of the two ends and the outer side of the middle part of the workpiece body 3 are matched by three edge matching grooves 221 in sequence, which can completely match the stacking of arc-shaped workpieces to be processed. This can not only avoid slight misalignment of the workpiece stacking, but also improve the smoothness of gripping and separation. Secondly, by positioning the pneumatic gripper 4 above the center of the circumcircle arc formed by the right triangle, the vertical positioning accuracy of the pneumatic gripper 4 in moving and gripping the material is improved, which is conducive to the pneumatic gripper 4 gripping the material from the center of gravity of the arc workpiece and achieving the effect of balanced gripping. Thirdly, the surface shape structure of the workpiece body 3 is divided into two parts: a single-piece workpiece-shaped claw groove 421 and another single-piece workpiece-shaped claw groove 421. Through the matching of the three edge matching grooves 221 and the single-piece workpiece-shaped claw groove 421 with various parts of the workpiece body 3, the accuracy of workpiece stacking and gripping can be further improved. This avoids insufficient contact gaps between the workpiece surface and the working surface of the claw block 420, making it easier to accurately move the workpiece to the tooling. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within the present invention.
