Abstract
Description
Technical Field
[0001] This utility model relates to the field of support tooling, specifically to a multi-purpose shock absorption mechanism. Background Technology
[0002] As times change, the market share of gasoline-powered vehicles is shrinking. New energy electric vehicles, based on battery technology, are gradually gaining a foothold in the market.
[0003] With the development of new energy vehicles, the product launch cycle is getting shorter and shorter, the replacement cycle of car companies is getting shorter and shorter, and various components are being customized in a diversified manner. In this environment, downstream casting companies are required to meet the needs of vehicle delivery at a faster speed and at a lower cost.
[0004] In downstream foundry enterprises, traditional fixed positioning supports or hydraulic floating supports are typically used to support castings during the production process. For example... Figure 7 The image shows a traditional fixed positioning support, which is a copper threaded stud with a support surface at the top and a threaded connection between the bottom and the tooling platform.
[0005] Traditional fixed supports ideally provide support and shock absorption for the product during use. However, in actual production, raw products often experience uncertain deformation. Therefore, fixed supports may actually exist in two states: 1. Reference Figure 8 1. The fixed support did not contact the product, thus failing to provide effective support and shock absorption; 2. Reference Figure 9 The deformation of the parts caused the fixed support to overshoot the positioning stroke, resulting in product deformation.
[0006] Hydraulic-assisted support can achieve better support and shock absorption, but it is expensive. Utility Model Content
[0007] The purpose of this invention is to provide a multi-purpose shock absorption mechanism that is low in cost and has a shock absorption and support effect within a certain range.
[0008] To achieve the above objectives, this utility model provides a multi-purpose shock absorption mechanism, which includes a hollow mounting base. A guide cylinder is detachably mounted on the upper end of the mounting base. A stepped pin is slidably inserted into the guide cylinder. A plug is mounted on the bottom end of the guide cylinder. An elastic support is provided between the plug and the stepped pin. The top end of the stepped pin extends out of the guide cylinder and is detachably mounted with a support head. A first stop surface for upper limit positioning is provided on the inner side of the guide cylinder, and a second stop surface for lower limit positioning is provided on the outer side of the stepped pin.
[0009] Preferably, the upper end of the guide cylinder is provided with an extension cylinder with an outer diameter smaller than that of its main body, the bottom of the support head is provided with a bottom groove that is slidably sleeved on the extension cylinder, the bottom of the bottom groove is provided with a screw hole, and the top of the stepped pin is provided with a stud that is threadedly engaged with the screw hole.
[0010] Preferably, the support head has a frustoconical portion that is narrower at the top and wider at the bottom in the middle, and a support block is provided at the upper end of the frustoconical portion.
[0011] Preferably, the outer side of the mounting base is fixedly fitted with a first outer hexagonal sleeve.
[0012] Preferably, the outer side of the guide cylinder is fixedly fitted with a second outer hexagonal sleeve.
[0013] Preferably, the bottom outer side of the guide cylinder is threadedly connected to the upper end of the mounting base.
[0014] Preferably, the outer side of the plug is threaded to the inner bottom side of the guide cylinder.
[0015] Preferably, the elastic support is a butterfly spring.
[0016] According to the above technical solution, this utility model provides a multi-purpose shock absorption mechanism, which includes a hollow mounting base. A guide cylinder is detachably mounted on the upper end of the mounting base. A stepped pin is slidably inserted into the guide cylinder. A plug is mounted on the bottom end of the guide cylinder. An elastic support is provided between the plug and the stepped pin. The top end of the stepped pin extends out of the guide cylinder and is detachably mounted with a support head. A first stop surface for upper limit positioning is provided on the inner side of the guide cylinder, and a second stop surface for lower limit positioning is provided on the outer side of the stepped pin.
[0017] The usage and beneficial effects of this multi-purpose vibration damping mechanism are as follows: When using this multi-purpose vibration damping mechanism, the mounting base is installed in the corresponding position on the tooling platform, with the support head facing upwards to support the part. When placing the part, the part presses against the support head, the support head presses against the stepped pin, and the stepped pin presses against the elastic support member, thus forming a good vibration damping effect. After the part is removed, the return action of the elastic support member causes the stepped pin to move upwards, so that the second stop surface contacts the first stop surface, producing an upward movement limiting effect. This multi-purpose vibration damping mechanism does not require complex and expensive hydraulic floating support components, has low manufacturing costs, and also has a certain range of vibration damping support effect.

Detailed Implementation
[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0032] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0033] See Figure 1-5 The multi-purpose shock absorber b shown includes a hollow mounting base 4. A guide cylinder 5 is detachably mounted on the upper end of the mounting base 4. A stepped pin 3 is slidably inserted into the guide cylinder 5. A plug 1 is mounted on the bottom end of the guide cylinder 5. An elastic support is provided between the plug 1 and the stepped pin 3. The top end of the stepped pin 3 extends out of the guide cylinder 5 and is detachably mounted with a support head 6. A first stop surface 14 for upper limit positioning is provided on the inner side of the guide cylinder 5, and a second stop surface 13 for lower limit positioning is provided on the outer side of the stepped pin 3.
[0034] When implementing the above technical solution and using the multi-purpose shock absorber mechanism b, see [reference needed]. Figure 6 The mounting base 4 of the multi-purpose shock absorber mechanism b is installed at the corresponding position on the tooling platform a, so that the support head 6 faces upward to support the part. When placing the part, the part presses against the support head 6, the support head 6 presses against the stepped pin 3, and the stepped pin 3 presses against the elastic support, thus forming a good shock absorption effect. When the part is removed, the return action of the elastic support causes the stepped pin 3 to move upward, so that the second stop surface 13 contacts the first stop surface 14, producing an upward movement limiting effect. This multi-purpose shock absorber mechanism b does not require complex and expensive hydraulic floating support components, has low manufacturing cost, and also has a certain range of shock absorption support effect.
[0035] In this embodiment, the upper end of the guide cylinder 5 is provided with an extension cylinder 9 whose outer diameter is smaller than that of its main body. The bottom of the support head 6 is provided with a bottom groove that slides onto the extension cylinder 9. The bottom of the bottom groove is provided with a screw hole 12, and the top of the stepped pin 3 is provided with a stud 11 that is threaded into the screw hole 12. With this arrangement, the support head 6 is installed on the upper end stud 11 of the guide cylinder 5 by means of threaded installation. After installation, the bottom of the support head 6 slides onto the upper end of the extension cylinder 9 and makes sliding contact with the extension cylinder 9, thereby increasing the dustproof performance.
[0036] In this embodiment, the support head 6 has a frustoconical portion 10 that is narrower at the top and wider at the bottom in the middle, and a support block is provided at the upper end of the frustoconical portion 10. This design reduces the support surface at the top of the support head 6, thus enabling more effective support for a wider range of part bottom surface types.
[0037] In this embodiment, a first hexagonal sleeve 7 is fixedly fitted onto the outer side of the mounting base 4. A second hexagonal sleeve 8 is fixedly fitted onto the outer side of the guide cylinder 5. The arrangement of the first and second hexagonal sleeves 7 and 8 facilitates the use of a wrench to rotate the mounting base 4 and guide cylinder 5, making assembly easier. For example, the bottom outer side of the guide cylinder 5 is threaded to the upper end of the mounting base 4; therefore, two wrenches can be used to engage the first and second hexagonal sleeves 7 and 8 respectively, rotating them in opposite directions to tighten the mounting base 4 and guide cylinder 5.
[0038] In this embodiment, the outer side of the plug 1 is threadedly connected to the inner bottom side of the guide cylinder 5. The lower end of the plug 1 is provided with an internal hexagonal hole for inserting an internal hexagonal wrench to tighten the plug 1.
[0039] In this embodiment, to further provide an elastic support member, the elastic support member is a butterfly spring 2.
[0040] The assembly method of this utility model is as follows: First, insert the stepped pin 3 into the guide cylinder 5 from bottom to top; second, install the butterfly spring 2 against the bottom of the stepped pin 3 into the guide cylinder 5; third, install the plug 1 against the lower end of the butterfly spring 2; fourth, screw the support head 6 onto the stud 11, so that the bottom groove slides around the extension cylinder 9; fifth, screw the guide cylinder 5 onto the mounting base 4. After completing the above installation, insert the assembled multi-purpose shock absorber b into the corresponding holes on the tooling platform a.
[0041] Under no load, the multi-purpose shock absorption mechanism b pushes the step pin 3 and the support head 6 upward along the guide cylinder 5 in the direction of the guide cylinder 5 under the action of the disc spring 2. When the workpiece is within the designed stroke range, the support head 6 will provide the elastic force of the disc spring 2 to the product or part, and fit the product within the stroke range to support and assist in shock absorption.
[0042] The travel range is the distance between the first stop surface 14 and the second stop surface 13.
[0043] This multi-purpose shock absorber b can be used like a hydraulic auxiliary support to maintain contact with the product, providing support and shock absorption, while also offering the lower price advantage of a fixed support. It can save a significant portion of the cost for the same output.
[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0046] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
