Description

Technical Field

[0001] The utility model relates to the technical field of spring preparation, in particular to a torsion spring end cutting device. Background Art

[0002] Torsion springs are rotation springs that include a spring body and two ends disposed at both ends of the spring body. The two ends of the torsion spring are fixed to other components. When the other components rotate around the center of the spring, the torsion spring pulls them back to their original positions to generate torque or rotational force.

[0003] At present, torsion springs are mainly formed by spring machines. However, due to the processing capacity of the spring machine tool (it is difficult for the tool to clamp too short a wire for processing), for torsion springs with very short end dimensions, the end dimensions of the torsion springs formed by the spring machine are difficult to meet the design requirements, especially the end length and the bending angle of the end are difficult to control (if the tool clamps the wire too long to ensure that the end bending angle is qualified, the end length will be unqualified; if the tool clamps the wire too short to ensure that the end length is qualified, the end bending angle will be unqualified). The accuracy of the end dimensions of the torsion spring affects the accuracy of the installation of the torsion spring and other components. Therefore, how to ensure that the end dimensions of the torsion spring are qualified is a problem that technicians in this field continue to work on solving. Utility Model Content

[0027] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0028] The torsion spring end cutting device of this embodiment is used to cut the end of the torsion spring so that the length of the torsion spring end meets the design standard.

[0029] like Figure 1 As shown, the torsion spring end cutting device of this embodiment mainly includes: a frame 1, a first driving source 2, a cutting tool 3, a second driving source 4, a mounting plate 5 and a positioning mechanism 6. Among them, the first driving source 2 and the second driving source 4 are arranged on the frame 1, the cutting tool 3 is connected to the output shaft of the first driving source 2; the mounting plate 5 is connected to the output shaft of the second driving source 4, and the positioning mechanism 6 is installed on the mounting plate 5 for positioning the torsion spring to be cut; the first driving source 2 is used to drive the cutting tool 3 to cut the torsion spring, and the second driving source 4 is used to drive the mounting plate 5 to move toward and away from the cutting tool 3 so that the end of the torsion spring can contact the cutting tool 3 to achieve the cutting of the end.

[0030] By adopting the above structure, the cutting device of this embodiment can cut the end of the torsion spring so that the size of the end of the torsion spring meets the design requirements. Therefore, when the torsion spring is formed by a spring machine, in order to ensure the forming accuracy of the bending angle of the end of the torsion spring, the wire of the tool clamping part can be appropriately lengthened. After the torsion spring is formed by the spring machine, the excessively long end of the torsion spring is cut by this device. In this way, the accuracy of the length dimension of the end of the torsion spring and the accuracy of the bending angle of the end can be ensured.

[0031] Specifically, Figure 1 and Figure 2 As shown, the positioning mechanism 6 of this embodiment includes a jig 61, a third driving source 62 and a positioning member. The jig 61 and the third driving source 62 are respectively fixed on the mounting plate 5, the jig 61 is used to carry the torsion spring to be cut, the positioning member is fixed on the output shaft of the third driving source 62, and the third driving source 62 drives the positioning member to move toward the jig 61 to fix the torsion spring to be cut on the jig 61. In this way, the torsion spring can be prevented from moving during cutting and affecting the cutting quality.

[0032] Furthermore, if Figure 2 As shown, the jig 61 of this embodiment includes a first groove 611 and a second groove 612 that are interconnected to facilitate the placement of the torsion spring. The first groove 611 is contoured to the main body of the torsion spring, and the second groove 612 is contoured to the end of the torsion spring to be cut. The end of the first groove 611 that is away from the second groove 612 passes through the end wall of the jig 61 to facilitate the placement of the torsion spring. The positioning member includes a positioning column 631 connected to the output shaft of the third driving source 62 and a positioning plate 632 connected to the positioning column 631. The positioning column 631 is used to penetrate from the end of the first groove 611 that is away from the second groove 612 to extend into the interior of the torsion spring body, and the positioning plate 632 is used to abut against the wire of the torsion spring. The third driving source 62 can be a pen-shaped cylinder.

[0033] Continue to refer to Figure 2 As shown, a waste box 7 is also provided on the mounting plate 5 of the present embodiment, and the waste box 7 is located beside the fixture 61. Further, the waste box 7 is located on the side of the fixture 61 away from the cutting tool 3 to collect the end waste cut off.

[0034] like Figure 1 As shown, the first driving source 2 of this embodiment may be a motor, and the cutting tool 3 may be a grinding wheel mounted on the output shaft of the motor.

[0035] Preferably, if Figure 3As shown, the motor of this embodiment can be installed on the frame 1 through an adjustment bracket. The adjustment bracket includes a plurality of fixed rods 81, a connecting plate 82, a screw 83, a slide 84 and a hand wheel 86. A plurality of fixed rods 81 are fixedly connected to the frame 1, and a plurality of connecting plates 82 are used to connect a plurality of fixed rods 81; the screw 83 is passed through the connecting plate 82, one end of the screw 83 is located above the connecting plate 82 and is fixedly connected to the hand wheel 86, and the other end of the screw 83 is located below the connecting plate 82 to be connected to the slide 84 through a screw nut 85; the motor is fixed on the slide 84. When the hand wheel 86 is turned, the motor (and the grinding wheel thereon) can be driven to move up and down by the rotation of the screw 83. With this solution, when the grinding wheel is worn, the motor can be adjusted downward by turning the hand wheel 86, thereby driving the grinding wheel to adjust its position downward to ensure that the grinding wheel can contact the end of the torsion spring.

[0036] like Figure 1 As shown, the second driving source 4 of this embodiment can be a rodless cylinder.

[0037] To sum up, the working process of the torsion spring end cutting device of this embodiment is as follows: the torsion spring to be cut at the end is placed in the jig 61, the third driving source 62 drives the positioning piece to move toward the jig 61, the positioning column 631 penetrates into the torsion spring, the positioning plate 632 presses against the wire at the end of the torsion spring, and the motor drives the grinding wheel to rotate. At the same time, the second driving source 4 drives the mounting plate 5 to move toward the grinding wheel so that the grinding wheel cuts the end of the torsion spring. After the cutting is completed, the waste falls into the waste box 7 located next to the jig 61 as the grinding wheel moves forward, and the second driving source 4 drives the mounting plate 5 to move away from the grinding wheel to repeat the cutting of the next torsion spring.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
