Description

Technical Field

[0001] The present application relates to the technical field of spring steel processing devices, and in particular to a supporting device for spring steel processing. Background Art

[0002] Spring steel is a special alloy steel used to manufacture various springs and other elastic components. It is generally divided into ordinary alloy spring steel and special alloy spring steel. Spring steel has excellent comprehensive performance, metallurgical quality and good surface quality, and is widely used in various fields.

[0003] According to the process requirements, when processing spring steel, it is necessary to first perform surface treatment or processing on the spring steel. The conventional processing method is to place the spring steel on the joint of the tooling for support and fixation, and then use the equipment to process the spring steel. However, the joint diameter of the conventional tooling is fixed. When the inner diameter of the spring steel deviates, it is difficult to insert and fix it. At this time, it is necessary to replace and debug a joint of another specification, which is time-consuming and labor-intensive, resulting in low processing efficiency. Utility Model Content

[0004] In order to improve the problem of low processing efficiency caused by poor adaptability of tooling joints in the related art, the utility model provides a supporting device for spring steel processing.

[0005] A support device for spring steel processing includes a base and a support seat arranged on the base, and also includes an expansion joint arranged on the side of the support seat away from the base, the expansion joint includes an elastic body, the inner side of the elastic body has an adapter cavity; an adapter cone pin for adjusting the outer diameter of the elastic body is slidably connected in the adapter cavity; an adjustment component is also arranged on the outer side of the elastic body.

[0006] Furthermore, the elastic body is provided with a plurality of open grooves along its circumference, and the plurality of open grooves divide the elastic body into a plurality of outwardly expanded blocks; and the adapting cone pin abuts against the inner wall of the outwardly expanded block.

[0007] Furthermore, the adapting cone pin comprises a cone pin body, the cone pin body is slidably connected to the elastic body, a fastener is disposed at one end of the cone pin body, and the fastener has an outer flange.

[0008] Furthermore, the outer diameter of the cone pin body gradually increases from an end close to the fastener to an end away from the fastener.

[0009] Furthermore, the outer flange sleeve is provided with an adapter gasket.

[0010] Furthermore, the adjustment assembly includes a limiting bracket detachably connected to the elastic body and an outer pad disposed on the limiting bracket, wherein the outer pad faces a side away from the adapting cone pin.

[0011] Furthermore, the elastic body is provided with a receiving groove, the limiting bracket includes a first supporting portion and a second supporting portion which are arranged in the receiving groove, and a supporting spring is arranged between the first supporting portion and the second supporting portion.

[0012] Furthermore, the first supporting portion is provided with a first hooking portion, and the second supporting portion is provided with a second hooking portion; the first hooking portion and the second hooking portion are hooked or detached from the accommodating groove.

[0013] The utility model has the following advantages:

[0014] 1. The utility model provides a support device for spring steel processing. By setting an expansion joint and an adaptor push pin, the expansion joint can adjust its outer diameter through an adaptor taper pin. When the spring steel needs to be fixed and processed, the spring steel is sleeved and installed in the expansion joint. Even if there is a processing error in the spring steel, the expansion joint with a smaller outer diameter can be installed. After the spring steel is installed, the outer diameter of the elastic body is adjusted by the adaptor taper pin. The outer diameter of the elastic body can be expanded to make the elastic body close to the inner wall of the spring steel, thereby stably supporting and fixing the spring steel without replacing and adjusting the tooling, thereby improving production efficiency.

[0015] 2. The supporting device of the utility model sets the outer diameter of the cone pin body to gradually decrease. When the adapter cone pin slides in the expansion joint, the end with the smaller outer diameter of the adapter cone pin drives the end with the larger outer diameter to move, which facilitates the sliding of the adapter cone pin in the expansion joint, thereby enabling better contact and transition with the expansion joint, making the expansion process of the expansion joint smooth.

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0026] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0030] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0031] Reference Figure 1 and Figure 2 A support device for spring steel processing includes a base 1 and a support seat 2 arranged on the base 1, and also includes an expansion joint 3 arranged on the side of the support seat 2 away from the base 1. When the support device is used, the initial outer diameter of the expansion joint 3 is small. After the annular spring steel sleeve is installed on the expansion joint 3, the outer diameter of the expansion joint 3 will increase to support and fix the spring steel. By setting the expansion joint 3 in this way, the adaptation problem caused by the processing error of the spring steel can be avoided.

[0032] Specifically, the base 1 is used to support the support base 2 and the expansion joint 3. The base 1 is provided with a plurality of mounting holes along its circumference, through which the base 1 can be conveniently installed and connected to other devices or equipment. The support base 2 is fixed to the base 1, and the support base 2 is located between the base 1 and the expansion joint 3. The support base 2 is used for transition to increase the distance between the expansion joint 3 and the base 1, so as to facilitate the installation of the spring steel and avoid direct contact between the spring steel and the base 1. At the same time, the base 1 and the support base 2 are provided with a communicating through hole to match the expansion joint 3 and the adapting cone pin 4.

[0033] The expansion joint 3 includes an elastic body 31, which is fixedly connected to one end of the support seat 2 away from the base 1. The elastic body 31 can be a part of the support seat 2, or a part independent of the support seat 2. In order to facilitate the installation of spring steel, the elastic body 31 is provided with a plurality of opening grooves 32 along its circumference. In this embodiment, there are six opening grooves 32, which are evenly arranged along the circumference of the elastic body 31. The six opening grooves 32 divide the elastic body 31 into six uniformly expanded blocks 312. The inner side of the elastic body 31, that is, the inner side of the expanded block 312, has an adapting cavity 311, which is connected to the through holes of the base 1 and the support seat 2.

[0034] An adapting cone pin 4 for adjusting the outer diameter of the elastic body 31 is slidably connected in the adapting cavity 311, and the adapting cone pin 4 abuts against the inner wall of the outward expansion block 312. In this embodiment, the adapting cone pin 4 includes a cone pin body 41, and the cone pin body 41 is slidably connected with the elastic body 31. By sliding the cone pin body 41, the cone pin body 41 can be driven to slide in the elastic body 31. The maximum outer diameter of the cone pin body 41 is larger than the inner diameter of the elastic body 31, so that when the cone pin body 41 slides in the elastic body 31, the elastic body 31 can be expanded, so that the outward expansion block 312 moves outward and abuts against the inner wall of the spring steel.

[0035] Reference Figure 3In addition, in order to conveniently drive the cone pin body 41, a fastener 42 for cooperating with an external device or apparatus is provided at one end of the cone pin body 41. The fastener 42 can be specifically provided at one end of the cone pin body 41 away from the base 1. The fastener 42 can be specifically installed and fixed with the cone pin body 41 in a threaded connection. The fastener 42 has an outer flange 421, which can be conveniently matched with an external device or apparatus through the outer flange 421, thereby driving the adapter cone pin 4 to slide in the elastic body 31. At the same time, since the outer flange 421 is easily worn due to long-term force, in order to extend the service life of the outer flange 421, the outer flange 421 is sleeved with an adapter gasket 43. In this embodiment, the adapter gasket 43 is sleeved on the side of the outer flange 421 close to the expansion joint 3. By providing the adapter gasket 43, it is possible to prevent the external device or apparatus from directly contacting the outer flange 421, thereby protecting the outer flange 421.

[0036] It is worth mentioning that, in order to facilitate the sliding of the cone pin body 41 in the expansion joint 3, the outer diameter of the cone pin body 41 gradually increases from the end close to the fastener 42 to the end away from the fastener 42. By setting the cone pin body 41 in this way, when the cone pin body 41 is driven to slide, the end with a smaller outer diameter of the cone pin body 41 first enters the elastic body 31, and then the end with a smaller outer diameter drives the end with a larger outer diameter to enter the elastic body 31 and cooperate with the outward expansion block 312, and finally the outward expansion block 312 spreads outward to cooperate with the spring steel.

[0037] Reference Figure 4 and Figure 5 Due to the processing error of spring steel, the inner ring cross-section of most spring steels is not completely circular. When the elastic body 31 with a circular outer diameter is matched with these spring steels, a gap will appear between the elastic body 31 and the inner wall of the spring steel, and the support for the spring steel is insufficient. In order to adapt to these spring steels, an adjustment component 5 is also provided on the outside of the elastic body 31. Specifically, the adjustment component 5 includes a limit bracket 51 detachably connected to the elastic body 31 and an outer pad 52 arranged on the limit bracket 51, and the outer pad 52 faces the side away from the adapting cone pin 4. By providing a detachable limit bracket 51 and an outer pad 52, the extension degree of the outer extension block can be further increased on a specific outer extension block, so as to match the irregular inner wall of the spring steel for filling, so that the expansion joint 3 can be pressed against the spring steel.

[0038] Reference Figure 6In this embodiment, the elastic body 31 is provided with a receiving groove 33, and the receiving groove 33 is located at each corner of the elastic body 31. The limiting bracket 51 includes a first support portion 511 and a second support portion 512 arranged in the receiving groove 33, the first support portion 511 and the second support portion 512 are rotatably connected, and a support spring 513 is arranged between the first support portion 511 and the second support portion 512, and the support spring 513 applies a force to move the first support portion 511 and the second support portion 512 away from each other. In addition, in order to achieve stable connection and support, the first support portion 511 is provided with a first hooking portion 5111, and the second support portion 512 is provided with a second hooking portion 5121, and the receiving groove 33 has a corresponding hooking groove, and the first hooking portion 5111 and the second hooking portion 5121 are hooked or disengaged from the hooking groove of the receiving groove 33. When the limiting bracket 51 is installed in the receiving groove 33 , the first hooking portion 5111 and the second hooking portion 5121 will simultaneously press against the hooking groove of the receiving groove 33 so that the position of the limiting bracket 51 is fixed.

[0039] The outer pad 52 is embedded between the limiting brackets 51, and the shape of the outer pad 52 is adapted to the shape of the outward expansion block 312. The outer pad 52 can be sponge, rubber, or the same material as the outward expansion block 312. By using one limiting bracket 51 to install an outer pad 52 with a certain thickness; or after installing multiple limiting brackets 51, multiple outer pads 52 with different thicknesses are installed in each of the multiple limiting brackets 51, the irregular inner wall of the spring steel can be filled and matched.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
