[0002] The shock-absorbing spring is a mechanical part that uses elasticity to work. Its two ends are in contact with different parts. Therefore, it is necessary to select a spring of appropriate length according to the distance between the parts. Generally, a cutting device is used to cut the spring to the appropriate length.

[0003] The existing spring cutting is usually carried out after measuring the length of the spring in its natural state, and it is impossible to directly obtain the spring length required under the specific compression force. Even standard springs will have performance errors. This cutting method will cause the actual performance of the spring to be inconsistent with the required performance in some applications. Therefore, the utility model proposes a shock-absorbing spring cutting device that can cut according to the actual elastic force effect. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1-Figure 3 As shown, a shock-absorbing spring cutting device proposed by the utility model comprises: a base 1 as an installation base, a fixed abutment plate 2 fixed to one end of the base 1, a movable abutment plate 3 slidably connected to the other end of the base 1 and compressing the spring 4 to be cut by sliding, a pressure sensor 5 located at the end of the spring 4 to be cut for sensing its compression elastic force, a cutting mechanism 6 installed on the base 1 for cutting the spring 4 to be cut, a second electric push rod 7 fixed to the upper surface of the base 1 for pushing the movable abutment plate 3 to translate, and a guide measuring column 8 for guiding the translation of the movable abutment plate 3 and indicating the cutting length;

[0030] The bottom of the fixed abutment 2 is fixedly connected to the upper surface of one end of the base 1, and the pressure sensor 5 is fixed to the side surface of the fixed abutment 2 facing the movable abutment 3. The spring 4 to be cut is placed between the fixed abutment 2 and the movable abutment 3, one end of which abuts against the pressure sensor 5 and the other end abuts against the movable abutment 3. As the output shaft of the second electric push rod 7 is extended and retracted, the movable abutment 3 can be pushed to translate, thereby compressing the spring 4 to be cut and sensing the compression elastic force of the spring through the pressure sensor 5. The pressure sensor 5 can also work in conjunction with the second electric push rod 7 through a matching controller. Since this working mode is extremely common, it will not be described here. In addition, in other embodiments, the second electric push rod 7 can also be replaced with a cylinder or other structure that can cause the movable abutment 3 to translate.

[0031] One end of the guide measuring column 8 is fixedly connected to the fixed support plate 2, and the other end is installed on the upper surface of the base 1 through a bearing seat. The movable support plate 3 is movably penetrated by the guide measuring column 8, so the guide measuring column 8 can provide horizontal guiding function for the movable support plate 3.

[0032] The cutting mechanism 6 includes a pair of bases 61 slidably sleeved with the guide measuring column 8, a first electric push rod 62 fixed to the top of each base 61, and a cutter 63 fixedly connected to the output shaft of the first electric push rod 62. The two cutters 63 are driven to move closer to each other by the extension and contraction of the output shaft of the first electric push rod 62, thereby cutting off the spring 4 to be cut in the middle. In other embodiments, other cutting tools such as laser cutters can also be installed on the base 61, and the replacement of the cutting tool does not affect the implementation of this solution;

[0033] The cutting mechanism 6 also includes a connecting arm 64 fixedly connecting the two bases 61, a threaded sleeve 65 fixed to the middle section of the connecting arm 64, and a threaded column 66 rotatably connected to the base 1 and threadedly engaged with the threaded sleeve 65. When the threaded column 66 is rotated, the threaded engagement between the threaded column 66 and the threaded sleeve 65 can be used to drive the two cutters 63 to translate along the threaded column 66 through the connecting arm 64 and the first electric push rod 62, thereby adjusting the cutting length of the spring 4 to be cut.

[0034] In this embodiment, the base 61 and the movable abutment plate 3 are both provided with a through hole 9 for the guide measuring column 8 to movably pass through. The upper side of the outer wall of the guide measuring column 8 is provided with a scale line, and the upper inner edge of the through hole 9 is provided with an anti-wear groove 91. The anti-wear groove 91 can prevent the scale line from directly contacting the inner ring surface of the through hole 9 and causing wear.

[0035] The working principle of this embodiment is: the device can be used to cut the required length of the spring in its natural state, and can also be used to cut the spring to the required length in the compressed state when the spring is compressed, so that the actual performance of the cut spring is more in line with the required performance.

[0036] Specifically, the spring 4 to be cut is placed between the fixed abutment plate 2 and the movable abutment plate 3 as shown in the figure, and the movable abutment plate 3 is driven to move to squeeze the spring 4 to be cut by the extension and contraction of the output shaft of the second electric push rod 7. The compression elastic force of the spring 4 to be cut is sensed by the pressure sensor 5. When the sensed value is 0, it means that the spring 4 to be cut is in a natural state. At this time, the cutting mechanism 6 can be moved to the desired position through the scale line on the guide measuring column 8, and the spring 4 to be cut can be cut into the desired length by the cutting mechanism 6.

[0037] When it is necessary to obtain a compression spring of corresponding length according to the actual application scenario, such as: when the distance between two parts in the application is determined, denoted as a, and the spring installed therein needs to reach a certain elastic force value, denoted as b, then in this embodiment, the spring 4 to be cut can be first compressed by moving the movable plate 3 until the pressure value sensed by the pressure sensor 5 reaches b, and then the cutting mechanism 6 is moved to the scale a on the corresponding guide measuring column 8, and then the spring length that meets the requirements can be cut.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
