Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically a chamfering device for spring processing. Background Technology

[0002] The chamfering device can precisely chamfer the ends of the spring, which not only improves the processing accuracy of the spring, but also makes the subsequent assembly process smoother. At the same time, the automated chamfering device can significantly improve production efficiency and reduce the time and cost of manual operation.

[0003] The principle of a chamfering device for spring machining mainly involves two aspects: positioning principle and cutting principle. By applying precise positioning and cutting principles, the chamfering device can efficiently produce chamfered springs that meet the requirements, providing strong support for the chamfering of springs.

[0004] Existing spring chamfering devices mostly chamfer springs by pressing and rotating multiple chamfering molds into the inside of the spring at both ends. However, during the chamfering process, spring positioning deviations can occur, resulting in uneven grinding of the chamfered area by the molds inside the spring. Therefore, a chamfering device for spring processing is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technology and address the problems of existing equipment, this utility model proposes a chamfering device for spring processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a chamfering device for spring processing, including a base, a bracket fixedly installed on the top of the base, a lifting plate arranged at the bottom center of the bracket, an mounting plate fixedly installed on the top of the lifting plate, a first drive motor fixedly installed at the top center of the mounting plate, a threaded rod installed through the interior of the mounting plate at the output end of the first drive motor, a nut threaded on the external end of the threaded rod, a movable block fixedly installed on the outside of the nut, connecting blocks fixedly installed on both sides of the movable block, drive blocks tightly attached to the outside of multiple connecting blocks, and telescopic springs fixedly installed between multiple drive blocks and the inner wall of the mounting plate, each telescopic spring having a first telescopic rod inside, a connecting groove opened on one side of the interior of each drive block, multiple connecting blocks slidably installed inside the connecting groove, a movable plate fixedly installed at one bottom end of each drive block, and a clamp fixedly installed on one side of one end of each movable plate. By pushing the drive block with the connecting block, a gap is provided between multiple clamps, and then the pressure is released by the telescopic spring, causing multiple clamps to fit together to achieve the effect of fixing the outside of the spring to be chamfered.

[0007] Preferably, a drive plate is provided at both ends of the top of the base, a second drive motor is fixedly installed on the top of the drive plate, a turntable is installed at the output end of the second drive motor, a mounting block is provided on the outer side of the turntable, a chamfering mold is fixedly installed on the outer side of the mounting block, a first limiting block is fixedly installed at each of the four outer ends of the mounting block, a limiting rod is fixedly installed on the side of a plurality of first limiting blocks, an installation groove is opened on the inner side of the turntable, the installation groove fits the shape of the mounting block and the first limiting block, and a first limiting groove is opened at each of the four inner ends of the turntable, the outer sides of a plurality of first limiting blocks are slidably installed inside the installation groove, and the outer sides of the limiting rods are slidably installed inside the first limiting groove, so that the chamfering mold can be quickly disassembled by pressing the first limiting block and pulling it out backward along the inside of the installation groove.

[0008] Preferably, the base has sliding grooves at both ends of its top, and electric slide rails are fixedly installed inside the multiple sliding grooves. Sliding blocks are slidably installed at both ends of the multiple electric slide rails, and the tops of the multiple sliding blocks are fixedly installed at the bottom of the drive plate. The sliding installation between the electric slide rails and the sliding blocks drives the drive plate and the chamfering mold to move, so that the chamfering mold moves to both ends of the inner wall of the spring to be chamfered for grinding and chamfering.

[0009] Preferably, cylinders are fixedly installed at both ends of the top of the bracket. The output ends of the cylinders pass through the inside of the bracket and are installed at both ends of the top of the lifting plate. The cylinders drive the lifting plate to move up and down, so as to drive the clamp to move upward when it is not necessary to chamfer the inside of the chamfering spring.

[0010] Preferably, the inner wall of the lifting plate is provided with a second limiting groove on both sides, and a second limiting block is slidably installed at both ends of the inner end of the multiple second limiting grooves. The sides of the multiple second limiting blocks are respectively fixedly installed on both sides of the driving block. By sliding the second limiting blocks inside the second limiting grooves, the driving block can be limited during the movement process, making its movement trajectory more stable and preventing deviation.

[0011] Preferably, a control panel is fixedly installed on the outer side of the bracket. The control panel is electrically connected to the first drive motor, the cylinder, and the second drive motor. The control panel is used to start and stop these components. Through the control panel, the operator can more conveniently start and stop the electronic equipment of the entire device.

[0012] Preferably, protective pads are fixedly installed on the inner walls of the multiple clamps. The protective pads are made of rubber. The rubber protective pads protect the outer surface of the spring from damage and wear when it is clamped. Furthermore, the elasticity of the rubber material can effectively protect the chamfered spring from excessive compression and deformation when it is squeezed.

[0013] The advantages of this utility model are: This invention utilizes a first drive motor to rotate a threaded rod, which increases the gap between the moving plate and the clamp. The spring to be chamfered is then placed between multiple clamps. At this point, the first drive motor reverses to stop pressing the drive block. The pressure is then released by the telescopic spring, shortening the gap between the multiple moving blocks and the clamps, thus fixing the chamfered spring externally. This external fixation ensures a more stable grinding process during chamfering, improving the uniformity of the chamfer. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5 As shown, a chamfering device for spring processing includes a base 1, a bracket 2 fixedly mounted on the top of the base 1, a lifting plate 3 disposed at the bottom center of the bracket 2, cylinders 17 fixedly mounted at both ends of the top of the bracket 2, the output ends of the cylinders 17 passing through the interior of the bracket 2 and mounted at both ends of the top of the lifting plate 3, a mounting plate 4 fixedly mounted on the top of the lifting plate 3, a first drive motor 5 fixedly mounted at the top center of the mounting plate 4, a threaded rod 6 mounted at the output end of the first drive motor 5 passing through the interior of the mounting plate 4, a nut 8 externally threaded onto one end of the threaded rod 6, and the nut 8 externally fixed... A movable block 7 is installed, and connecting blocks 9 are fixedly installed on both sides of the movable block 7. Multiple connecting blocks 9 are tightly attached to the exterior of a drive block 10. Multiple drive blocks 10 are fixedly installed between themselves and the inner wall of the mounting plate 4. A first telescopic rod 13 is provided inside the telescopic spring 12. A connecting groove 11 is opened on one side of the interior of each drive block 10. Multiple connecting blocks 9 are slidably installed inside the connecting groove 11. A movable plate 14 is fixedly installed at one bottom end of each drive block 10. A clamp 15 is fixedly installed on one side of one end of each movable plate 14. Both sides of the inner wall of the lifting plate 3 are provided with... The second limiting groove 30 has two ends of which are slidably fitted with second limiting blocks 31. The sides of the multiple second limiting blocks 31 are respectively fixedly installed on both sides of the drive block 10. During operation, in order to make the spring to be chamfered more stable during the chamfering process, the first drive motor 5 is started to drive the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the moving block 7 to move downward. When the moving block 7 moves downward, it will drive the connecting blocks 9 on both sides to squeeze the multiple drive blocks 10 and make them move backward. When the drive blocks 10 move backward, it will increase the gap between the moving plate 14 and the clamp 15. When the clamp 1 When the gap between 5 increases, the spring to be chamfered is placed between multiple clamps 15. Then, the first drive motor 5 reverses to drive the moving block 7 to move upward. When the moving block 7 moves upward, the connecting blocks 9 on both sides of it stop pressing the drive block 10. At this time, the telescopic spring 12, which is fixedly installed on both sides of the inner wall of the mounting plate 4 and between one side of multiple drive blocks 10, is no longer compressed and releases its elastic force. At this time, the force applied by the telescopic spring 12 reaches its maximum. By releasing the pressure through the telescopic spring 12, the gap between multiple moving plates 14 and clamps 15 is shortened, achieving the effect of fixing the outside of the spring to be chamfered.

[0018] Both ends of the top of the base 1 are provided with drive plates 20. Both ends of the top of the base 1 are provided with sliding grooves. Electric slide rails 18 are fixedly installed inside the multiple sliding grooves. Sliding blocks 19 are slidably installed at both ends of the multiple electric slide rails 18. The tops of the multiple sliding blocks 19 are fixedly installed at the bottom of the drive plate 20. A second drive motor 21 is fixedly installed on the top of the drive plate 20. A turntable 22 is installed at the output end of the second drive motor 21. A mounting block 24 is provided on one side of the turntable 22. A chamfering mold 25 is fixedly installed on one side of the mounting block 24. First limit blocks 26 are fixedly installed at all four ends of the outer side of the mounting block 24. Limit rods 27 are fixedly installed on the sides of the multiple first limit blocks 26. An installation groove 23 is provided on one side of the inside of the turntable 22. The installation groove 23 is connected to the mounting block 24 and the first limit blocks. The shapes of the 26 blocks fit together, and the four ends of one side of the turntable 22 are provided with first limiting grooves 28. The external parts of the multiple first limiting blocks 26 are slidably installed inside the mounting groove 23, and the external parts of the limiting rods 27 are slidably installed inside the first limiting grooves 28. During operation, in order to quickly replace the chamfering mold 25 that has been used for a long time, the multiple limiting rods 27 are pressed inward to disengage them from the inside of the first limiting grooves 28. When the limiting rods 27 are disengaged from the connection between them and the first limiting grooves 28, the chamfering mold 25 is rotated, which causes the mounting block 24 and the first limiting blocks 26 fixedly installed at its four ends to rotate. When the rotation angle of the multiple first limiting blocks 26 is in contact with the mounting groove 23 on one side of the turntable 22, the chamfering mold 25 is moved backward to achieve the effect of quickly disassembling the chamfering mold 25.

[0019] A control panel 29 is fixedly installed on the outer side of the bracket 2. The control panel 29 is electrically connected to the first drive motor 5, the cylinder 17, and the second drive motor 21. The control panel 29 is used to start and stop them. During operation, in order to make it easier for operators to control the whole device, the control panel 29 is used to start and stop multiple electronic devices, making it more convenient to use.

[0020] Protective pads 16, made of rubber, are fixedly installed on the inner walls of multiple clamps 15. During operation, existing clamps 15 mostly fix springs by directly contacting them with metal clamps 15. However, the rubber protective pads 16 on the side of the clamps 15 can protect the outer surface of the spring from damage and wear when it is clamped. Furthermore, the elasticity of the rubber material can effectively protect the chamfered spring from excessive compression and deformation when it is squeezed.

[0021] Working principle: Existing spring chamfering devices mostly chamfer springs by pressing and rotating multiple chamfering molds 25 into the inside of the spring at both ends. However, during the chamfering process, spring positioning deviations can lead to uneven grinding of the chamfered area by the molds. Starting the first drive motor 5 drives the threaded rod 6 to rotate, which in turn moves the moving block 7 downwards. When the moving block 7 moves downwards, it causes the connecting blocks 9 on both sides to press multiple drive blocks 10 backwards. As the drive blocks 10 move backwards, the gap between the moving plate 14 and the clamp 15 increases. When the clamp... When the gap between clamps 15 increases, the spring to be chamfered is placed between multiple clamps 15. Then, the first drive motor 5 reverses to drive the moving block 7 upward. When the moving block 7 moves upward, the connecting blocks 9 on both sides of it stop pressing the drive block 10. At this time, the telescopic spring 12, which is fixedly installed on both sides of the inner wall of the mounting plate 4 and one side of the multiple drive blocks 10, is no longer compressed and releases its elastic force. At this time, the force applied by the telescopic spring 12 reaches its maximum. By releasing the pressure through the telescopic spring 12, the gap between the multiple moving plates 14 and the clamps 15 is shortened, achieving the effect of fixing the outside of the spring to be chamfered. When the spring to be chamfered... After the angle spring is fixed, the sliding block 19 moves via the electric slide rail 18. The movement of the sliding block 19 then moves the drive plate 20. When the drive plate 20 moves, it drives the second drive motor 21, connected to its output end, to move the chamfering mold 25. When the chamfering mold 25 moves to the inner walls of both ends of the spring to be chamfered, it is pressed tightly against the inner walls, and the electric slide rail 18 stops moving. The second drive motor 21 is then activated to rotate the chamfering mold 25, achieving the chamfering effect on the inner angles of the spring. When the chamfering mold 25 wears down after prolonged chamfering, it is then adjusted by... Multiple limiting rods 27 are pressed inward to disengage them from the interior of the first limiting groove 28. The limiting rods 27 are multi-segment telescopic structures and have springs inside to automatically reset them after use. When the limiting rods 27 are disengaged from the connection between them and the first limiting groove 28, the chamfering mold 25 is rotated. The rotation of the chamfering mold 25 drives the mounting block 24 and the first limiting blocks 26 fixed at its four ends to rotate. When the rotation angle of the multiple first limiting blocks 26 is in contact with the mounting groove 23 opened on one side of the turntable 22, the chamfering mold 25 is moved backward to achieve the effect of quickly disassembling the chamfering mold 25.
