Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a ring-shaped workpiece feeding tool. Background Art

[0002] The assembly of automotive parts requires a wide variety of circular workpieces, including retaining rings, retaining rings, and bearings. On existing assembly lines, the multiple annular workpieces that comprise the same product are fed through a loading fixture. A loading cylinder drives a loading plate to push out the annular workpieces, and a robotic arm retrieves the workpieces from different loading fixtures. This method poses a risk of material jamming during the loading process, as the loading plate, carrying the workpieces, returns, potentially damaging the workpieces. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a ring-shaped workpiece feeding tool for solving the problem in the prior art that the feeding plate carrying the ring-shaped workpiece is easily stuck during the feeding and returning process.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides a ring-shaped workpiece loading fixture, comprising a base and a workbench provided at the upper end of the base, wherein the upper end of the workbench is provided with a blanking limit block, and the blanking limit block is provided with a center hole;

[0005] The upper end of the workbench is further connected to a fixed plate through a bracket, and a loading rod is installed on the fixed plate, and the annular workpiece is stacked on the loading rod; the lower end of the loading rod is inserted into the center hole and is suspended relative to the workbench;

[0006] The feeding rod is provided with a pressing block, which presses the upper end of the annular workpiece. The annular workpiece is discharged from the lower end of the feeding rod in sequence due to the downward pressure of the pressing block.

[0007] The upper end of the base is equipped with a feeding cylinder, the output end of the feeding cylinder is connected to a feeding tooling plate, a feeding position is provided on the feeding tooling plate, and the feeding tooling plate can be movably matched between the workbench and the blanking limit block. The feeding tooling plate receives the annular workpiece discharged from the lower end of the feeding rod through the feeding position and is driven by the feeding cylinder to push out the feeding;

[0008] Positioning mechanisms are provided on both sides of the workbench, and the two positioning mechanisms can movably lock the annular workpiece stacked on the feeding rod and located at the lower end from opposite sides.

[0009] In one embodiment of the present invention, support blocks are provided on both sides of the workbench, the positioning mechanism is mounted on the support blocks, and the blanking limit blocks are provided on the upper ends of the two support blocks at the same time;

[0010] The height of the support block is greater than the height of the workbench, so that a channel capable of accommodating the advancement and retraction activities of the loading tooling plate exists between the blanking limit block and the workbench.

[0011] In one embodiment of the present invention, the two positioning mechanisms are identical mechanisms, both comprising a positioning cylinder and a positioning block connected to an output end of the positioning cylinder.

[0012] In one embodiment of the present invention, the side ends of the blanking limit blocks corresponding to the two positioning mechanisms are provided with limit slots extending through the center hole, and the positioning blocks can movably pass through the limit slots to contact the annular workpiece stacked on the loading rod and located at the lower end.

[0013] In one embodiment of the present invention, a V-shaped clamping opening is provided at the lower end of the contact surface of the positioning block.

[0014] In one embodiment of the present invention, a pair of matched detection sensors are provided at the front end of the workbench for detecting the state of the annular workpiece in the loading position being taken out when the loading fixture plate pushes out the loading.

[0015] In one embodiment of the present invention, a buffer is provided on the rear end edge of the loading tooling plate, and the buffer moves with the loading tooling plate to form a collision buffer between the loading tooling plate and the support block.

[0016] In one embodiment of the present invention, the diameter of the pressing block is larger than the diameter of the annular workpiece, and the diameter of the center hole of the blanking limiting block is larger than the diameter of the pressing block.

[0017] As described above, the annular workpiece loading fixture of the present invention has the following beneficial effects:

[0018] 1. By setting up two positioning mechanisms that work together, when the loading cylinder drives the loading tooling plate to load the material, the two positioning mechanisms can lock the annular workpiece stacked on the loading rod and located at the lowest end, preventing the loading tooling plate from getting stuck on the annular workpiece on the loading rod when returning, preventing the annular workpiece from being stuck and deformed, and improving the loading effect;

[0019] 2. By suspending the feeding rod and using it in conjunction with the pressing block, multiple annular workpieces constituting the same product can be placed on the feeding rod in a stacked state according to the assembly sequence. The self-gravity of the pressing block can press down to enable the annular workpieces to be discharged from the lower end of the feeding rod in sequence, without the need for additional driving force, thus saving feeding costs. The setting of the blanking limit block can limit the circumferential swing of the lower end of the feeding rod, thereby improving the accuracy of the discharge position of the lower end of the feeding rod;

[0020] 3. The present invention adds a positioning mechanism on the basis of the existing technology. After the previous material is pushed out, the positioning mechanism will clamp, position and fix the next material, effectively solving the problem of the loading tooling plate returning and getting stuck. Both positioning mechanisms are driven by positioning cylinders to be retractable and movable, and can lock annular workpieces of different diameters. They have good compatibility and are widely applicable on the production line. BRIEF DESCRIPTION OF THE DRAWINGS
