Description

Technical Field

[0001] The utility model relates to the technical field of spring production, in particular to a cutting limit clamp for a spring production device. Background Art

[0002] A spring is a mechanical part that works using elasticity. A part made of elastic material deforms under the action of an external force and returns to its original shape after the external force is removed. Also known as "spring". Generally made of spring steel. Springs are complex and diverse in types. Classified by shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] However, there are some problems in the prior art: for some springs at the present stage, when cutting, they cannot effectively clamp the springs according to the size of the springs, thus reducing the effective range of the device for cutting springs, which is not conducive to long-term use. Therefore, we propose a cutting limit clamp for a spring production device. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide a cutting limit clamp for a spring production device with a wide application range, a simple structure and convenient use.

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0021] As Figures 1-4 shown, a cutting limit fixture for a spring production device includes a base 1, and the base is U-shaped;

[0022] An opposed movement structure is installed in the base, and the opposed movement structure is used to drive two end clamping assemblies 2 to approach or move away from each other;

[0023] Two groups of support structures 3 and a movement structure for driving the support structures to move are installed in the base.

[0024] In this way, according to the diameter of the spring 4, the end clamping assembly is adjusted for adaptation. According to the position where the spring needs to be cut, the position of the support structure is adjusted through the movement structure, so that the two groups of support structures are located on both sides of the spring cutting position. The spring is placed on the support structure, and the opposed movement structure drives the end clamping assembly to move, clamping and limiting the end of the spring, and then the spring can be cut by using a cutting tool.

[0025] During implementation, the opposed movement structure includes a bidirectional screw 5. The two ends of the bidirectional screw are connected to the support by bearings, the support is fixedly installed on the base, one end of the bidirectional screw passes through the support and is fixedly connected to the output shaft of a first servo motor 6, the first servo motor is fixedly installed on the support, two nuts are threadedly connected to the bidirectional screw, the nuts are fixedly installed on the support block 7, the support block is slidably matched with the base, and an end clamping assembly is fixedly installed on the support block.

[0026] In this way, the first servo motor drives the bidirectional screw to rotate, drives the subsequent fast movement through the nut, and then drives the end clamping assembly to move. Driving the two end clamping assemblies to approach or move away from each other through the bidirectional screw can quickly realize the position adjustment between the two end clamping assemblies and is convenient for use.

[0027] During implementation, the end clamping assembly includes a mounting base 11 fixedly installed on the support block. A frame 12 is fixed on the mounting base. Four lead screws 13 are rotatably installed on the frame. The end of the lead screw away from the frame is connected to the mounting base through a bearing block 14. A driven bevel gear is fixed to the end of the lead screw located inside the frame. A gear shaft is rotatably installed on the mounting base. A driving bevel gear meshing and driving with the driven bevel gear is fixedly installed on the gear shaft. A nut block 15 is threadedly connected to the lead screw. A slider is fixed to the nut block. A chute is formed in the mounting base. The slider is slidably matched with the chute. An arc-shaped clamping plate 16 is fixed to the end of the slider away from the nut block.

[0028] In this way, by rotating the gear shaft, the driving bevel gear drives the driven bevel gear and the lead screw to rotate, thereby driving the nut block, the slider and the arc-shaped clamping plate to move, adapting to springs of different diameters.

[0029] During implementation, a knob 17 is fixed to the end of the gear shaft. It is convenient to rotate the gear shaft.

[0030] During implementation, the support structure includes a bracket 21. Both sides of the bracket are connected to the moving structure through connecting frames 22. Both sides of the bracket have inclined plates inclined outward. A cylinder 23 is fixed below the inclined plate. The piston rod of the cylinder passes through the inclined plate and is fixedly connected to a support plate 24.

[0031] In this way, the bracket supports the spring, and the cylinder drives the support plate to move. The support plate provides auxiliary support for the spring, improving the support stability.

[0032] During implementation, the moving structure includes two one-way lead screws 25. Support blocks are fixed to both sides of the connecting frame. Nuts threadedly connected to the one-way lead screws are fixed to the support blocks. A long groove is formed in the base. The support blocks are slidably matched with the long groove. An intermediate block 27 and an end block 28 are fixed to the base. The two ends of the one-way lead screw are respectively rotatably connected to the intermediate block and the end. The one-way lead screw passes through the end block and is fixedly connected to the output shaft of a second servo motor 292. The second servo motor is fixedly installed on the base.

[0033] In this way, the second servo motor drives the one-way lead screw to rotate, thereby driving the support blocks and the bracket to move.

[0034] Specifically, the intermediate block is arranged between the two long grooves. The two ends of the intermediate block are respectively connected to the one-way lead screws of the moving structures on both sides through bearings.

[0035] Finally, it should be noted that those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, the present utility model is also intended to include these modifications and variations.
