[0002] Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts that are frequently assembled and disassembled. When processing spring washers, twisting equipment is generally used, and the twisting equipment is used to twist, shear or deform metal parts or other material parts to achieve the required shape and size. In addition, the twisting equipment needs to use a positioning device when processing spring washers, which can ensure that the spring washers maintain a stable position during the processing process, reduce processing defects caused by position deviation, and make the spring washers do not need frequent post-processing to correct position deviations after processing. However, the spring washers are stably inserted into the positioning device, and their size and distance from the inside of the positioning device are fixed, so that the outside of the spring washers and the positioning device are easily frictional, causing the spring washers to shake and shift in position when they are located inside the positioning device, thereby causing the spring washers to deviate from the pre-set positioning point position, and the position of the spring washers needs to be adjusted repeatedly, which affects the accuracy of the positioning of the elastic washers, increases the time required for the positioning of the spring washers, and reduces the processing efficiency of the twisting equipment for the spring washers.

[0019] The positioning assembly 2 is used to accurately position the workpiece in the positioning groove 13. The positioning assembly 2 includes a guide groove 21 opened on one side of one of the fixed plates 12 and communicating with the interior of the positioning groove 13, two fixed bevel blocks 22 symmetrically installed in the guide groove 21, and two positioning clamps 24 installed at one end of the two fixed bevel blocks 22, and the two positioning clamps 24 are located in the positioning groove 13. A connecting frame 25 is fixed to the bottom of one of the fixed plates 12, and a power assembly for pushing the two fixed bevel blocks 22 to move is provided on the connecting frame 25. An ejection assembly 3 is provided in the power assembly, and the ejection assembly 3 is used to push the workpiece inside the positioning assembly 2 and push the workpiece into the collection tray 14.

[0020] The power assembly includes a push block 23 slidably installed between two fixed and inclined blocks 22, a push rod 26 fixed on one side of the push block 23, and a push cylinder 27 installed on one side of the connecting frame 25. The push cylinder 27 is used to drive the push rod 26 to slide. Push rod sliders 29 are fixed at both ends of the push block 23, and a push groove 28 for the push rod sliders 29 to slide is opened on one side of the two fixed and inclined blocks 22.

One end of the gear 36 is mounted There is a swing arm rod 37, a connecting column 34 is installed at one end of the swing arm rod 37, and a sliding groove 38 for the connecting column 34 to slide is opened on one side of the push rod 33; the stabilizing component 4 includes an axial rod column 44 fixed at one end of the gear 36 and a movable groove 42 opened on one side of the push rod 26 for the axial rod column 44 to slide, a rotatable connecting seat 43 is installed at one end of the axial rod column 44, and a stabilizing frame 41 is fixed to the top of the positioning frame 31, and the stabilizing frame 41 extends into the movable groove 42 and is fixed to the outside of the connecting seat 43.

[0022] When the workpiece is twisted off during processing, the workpiece is first placed in the positioning groove 13 and between the two positioning clamps 24, and there is a large distance between the two positioning clamps 24 and the workpiece. The push cylinder 27 is pushed to extend and retract to drive the push rod 26 to slide along the guide groove 21 toward the connecting frame 25, and then the push rod 26 moves to drive the push block 23 to slide between the two fixed bevel blocks 22. At this time, the push block 23 moves to drive the push rod slider 29 to slide along the push groove 28 and pull the two fixed bevel blocks 22 to slide relative to each other. As the two fixed bevel blocks 22 move, the two positioning clamps 24 are driven to approach and fit the two sides of the workpiece, reducing the workpiece in the positioning groove 13. When shaking occurs, the moving frame 15 drives one of the fixed plates 12 to approach the other fixed plate 12, and then the two fixed plates 12 fit and restrict the workpiece in the positioning groove 13, so that the workpiece is firmly restricted in the positioning groove 13 on all sides, so that the two positioning clamps 24 can fit the workpiece, which can reduce the friction of the workpiece in the positioning groove 13, which is conducive to the accurate placement of the workpiece at the pre-set positioning point in the positioning groove 13, and the accuracy of workpiece positioning is increased. The part of the workpiece that needs to be processed is exposed outside the positioning groove 13, and the exposed part of the workpiece is processed by twisting off the ejector rod 11. The twisting process is performed to complete the twisting process of the workpiece; and the twisted workpiece is collected by the collecting plate 14. At this time, the push cylinder 27 pushes the push rod 26 to slide along the connecting frame 25 into the guide groove 21, so that the two positioning clamps 24 slide toward each other, and the push rod 26 moves to drive the rack 35 to slide, and the rack 35 slides and meshes with the gear 36 to drive the gear 36 to rotate along the push rod 26, and the rotation of the gear 36 drives the shaft column 44 to rotate along the connecting seat 43. At the same time, the sliding between the moving groove 42 and the shaft column 44 keeps the position of the gear 36 unchanged, so that the rotation of the gear 36 drives the pendulum The arm rod 37 rotates, and as the swing arm rod 37 rotates, it drives the ejection rod 33 to slide up and down along the slide groove 38 and pushes the ejection rod 33 to move forward and backward along the positioning frame 31, and then the push plate 32 slides along the positioning frame 31 and moves out of the guide groove 21, pushing the workpiece to move in the two positioning clamps 24, which is conducive to the workpiece sliding and disengaging in the two positioning clamps 24, and facilitating the rapid removal of the processed workpiece in the positioning groove 13 and sliding it into the through groove, and then the through groove transports the workpiece inside it to the collection tray 14, so that the processed workpiece can be collected without waiting, further improving the processing efficiency of the twisting equipment on the workpiece.

[0025] Through the above technical solution: When the workpiece is pushed, the bonding plate 57 first contacts the workpiece in advance under the movement of the push plate 32, and then the push plate 32 continuously slides along the positioning frame 31. At this time, the connecting frame 54 and the second push ring 55 move along the baffle 56 and contact the protruding part of the baffle 56, so that the connecting frame 54 rotates along the connecting seat 52 and drives the first push ring 53 to move, so that the first push ring 53 moves and pushes the bonding plate 57. As the bonding plate 57 moves, the reset rod 61 slides along the extension groove 62 in the direction of the force, and then the reset rod The movement of 61 drives the gasket 63 to slide along the reset groove 66, and the reset spring 64 is squeezed between the gasket 63 and the reset groove 66. At the same time, the gasket 63 moves to slide the limiting hole opened at one end thereof along the outside of the limiting column 65, so that the bonding plate 57 can be slid along one side of the push plate 32, so that the bonding plate 57 has an extension effect on one side of the push plate 32, which is convenient for the secondary push of the workpiece in the positioning clamp 24, and can more evenly distribute the pushing stress, reduce the internal stress concentration of the workpiece, and facilitate the effective collection of the workpiece.
