Abstract
Description
Technical Field
[0001] The utility model relates to the field of spring machines, in particular to a high-efficiency spring machine and a cam component thereof. Background Art
[0002] A spring machine is a device used to produce springs. The spring machine is equipped with a cam member and a motor. When the motor drives the cam member to rotate, the convex position formed by the cam member drives the connecting piece on the spring machine to deflect, and the connecting piece drives the spring shaft of the spring machine to reciprocate to process the spring. The faster the frequency of the reciprocating motion of the spring shaft, the higher the production efficiency of the spring machine will be.
[0003] Since the conventional cam member is provided with only one convex position, one rotation of the cam member will drive the spring shaft to realize one reciprocating motion. In order to improve the production efficiency of the spring machine, the manufacturer has two solutions.
[0004] One method is to increase the rotation speed of the cam member by increasing the rotation speed of the motor, thereby shortening the time required for a single reciprocation of the spring shaft to increase the reciprocating speed of the spring shaft. However, increasing the motor speed will inevitably increase the amount of electricity required for the spring machine to operate, resulting in higher operating costs for the spring machine, and high-speed rotation will also shorten the service life of the motor.
[0005] The other method is to use the motor to drive the convex position to quickly reset to increase the reciprocating speed of the spring shaft. However, the frequent forward and reverse rotation of the motor is prone to short circuit, which not only increases the maintenance cost, but also affects normal production. Utility Model Content

[0030] refer to Figure 1 The high-efficiency spring machine according to a preferred embodiment of the present invention will be described in detail below. The high-efficiency spring machine includes a device body 10 and a cam member 20.
[0031] refer to Figure 1 and Figure 2 The equipment body 10 includes at least one belt rotating part 11, at least one connecting part 12, at least one spring shaft 13 and a workbench 14.
[0032] The cam member 20 is rotatably connected to the belt rotator 11. In one example, the belt rotator 11 may be implemented to include a motor.
[0033] The spring shaft 13 is mounted on the workbench 14. The connecting member 12 is rotatably connected to the workbench 14, wherein one end of the connecting member 12 is connected to the spring shaft 13, and one end of the connecting member 12 away from the spring shaft 13 is close to the cam member 20. The end of the spring shaft 13 away from the connecting member 12 can be close to or away from the spring to process the spring. The workbench 14 forms a feed hole for the raw material of the spring to pass through to make the spring, and the spring shaft 13 is distributed on the workbench 14 along the axial circumference of the feed hole.
[0034] refer to Figure 3 The cam member 20 includes a cam body 21 , and the cam body 21 is formed with a plurality of protrusions 211 spaced apart in radial direction, and a groove 2101 is formed between two adjacent protrusions 211 .
[0035] refer to Figures 1 to 3 , the belt rotating member 11 drives the cam member 20 to rotate so that the spring shaft 13 has a working state and a reset state. In the working state, the end of the connecting member 12 away from the spring shaft 13 is lifted by the protruding portion 211, so that the spring shaft 13 moves toward the position of the spring along its own axis to process the spring. In the reset state, the end of the connecting member 12 away from the spring shaft 13 can be clamped in the groove 2101, so that the spring shaft 13 moves along its own axis in a direction away from the spring, thereby resetting.
[0036] The belt rotating part 11 drives the cam member 20 to rotate one circle, and the spring shaft 13 can realize the working state and the reset state to alternate multiple times, so that the spring shaft 13 can reciprocate multiple times, thereby improving the production efficiency of the high-efficiency spring machine.
[0037] refer to Figure 3 The cam body 21 is formed with a mounting groove 2102 and a through opening 2103 communicating with the mounting groove 2102 at each protruding portion 211 .
[0038] The cam member 20 further includes a plurality of adjustment components 22 and a plurality of locking members 23. The locking members 23 are used to fix the adjustment components 22. The adjustment components 22 are installed in the installation slot 2102, and the adjustment components 22 can move along the extension direction of the installation slot 2102. In other words, the adjustment components 22 can extend or retract from the installation slot 2102 through the through opening 2103. The locking members 23 pass through the adjustment components 22 and are connected to the cam body 21, so that the locking members 23 lock the adjustment components 22 and the cam body 21.
[0039] After the adjusting assembly 22 is retracted into the installation slot 2102, the connecting member 12 may be lifted up to a predetermined height by the protruding portion 211. It is understandable that after the adjusting assembly 22 is extended out of the installation slot 2102, the end of the connecting member 12 away from the spring shaft 13 is lifted up by the adjusting assembly 22 to a height greater than the predetermined height, thereby changing the movement stroke of the spring shaft 13, thereby meeting the production requirements for springs of different models.
[0040] refer to Figure 4 and Figure 5The adjusting component 22 includes a toggle member 221 and an adjusting member body 222. The adjusting member body 222 is connected to the toggle member 221. The toggle member 221 and the adjusting member body 222 are arranged in the mounting groove 2102. The mounting groove 2102 includes a first groove body 21021 and a second groove body 21022, the first groove body 21021 is connected to the second groove body 21022, and the second groove body 21022 is connected to the through opening 2103. The groove width of the second groove body 21022 is adapted to the width of the adjusting member body 222, so that the second groove body 21022 limits the moving direction of the adjusting member body 222. The groove width of the first groove body 21021 is greater than the width of the toggle member 221. That is to say, there is a gap between the toggle member 221 and the inner wall of the first slot 21021, so that a person's fingers can be inserted into the first slot 21021 to hold the toggle member 221 to toggle the adjustment component 22 to move along the extension direction of the installation slot 2102, thereby adjusting the length of the adjustment component 22 extending out of the opening 2103.
[0041] refer to Figure 5 and Figure 6 Each locking member 23 includes a rod portion 231 and a limiting end 232 , one end of the rod portion 231 expands radially to form the limiting end 232 , and one end of the rod portion 231 away from the limiting end 232 is detachably connected to the cam body 21 .
[0042] Preferably, the cam body 21 forms a threaded hole 2104, and the adjustment assembly 22 forms at least one limiting structure 223 at the adjustment member body 222. The locking member 23 is inserted into the limiting structure 223 and threadedly connected with the threaded hole 2104, so that the locking member 23 is threadedly connected with the cam body 21 through the threaded hole 2104, so that the locking member 23 and the cam body 21 cooperate to fix the adjustment assembly 22.
[0043] In a preferred embodiment, the limiting structure 223 is implemented as a perforation and multiple perforations are provided. The multiple perforations are distributed along the length direction of the adjusting member body. The locking member 23 is threadedly installed in the threaded hole 2104 after passing through any of the perforations, so that the locking member 23 fixes the adjusting assembly 22 to the cam body 21. It can be understood that the locking member 23 can be connected with the threaded hole 2104 by passing through the perforations at different positions, thereby limiting the telescopic degree of the adjusting assembly 22.
[0044] In another preferred embodiment, the limiting structure 223 is implemented as a waist-shaped groove, and the limiting structure 223 extends a predetermined length along the length direction of the adjusting member body 222. The rod portion 231 of the locking member 23 passes through the waist-shaped groove and is threadedly connected with the threaded hole 2104 until the limiting end 232 abuts against the adjusting member body 222, so that the limiting end 232 and the cam body 21 cooperate to fix the adjusting assembly 22. In this way, when the limiting end 232 is separated from the adjusting member body 222, the adjusting member body 222 can move along the extension direction of the mounting groove 2102, thereby adjusting the length of the adjusting member body 222 extending out of the through opening 2103.
[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
