Description

Technical Field

[0001] This utility model relates to the field of rubber buffer sleeve technology, specifically a tooling for axial durability testing of rubber buffer sleeves. Background Technology

[0002] A rubber buffer sleeve is a sleeve-shaped component made of rubber material with a cushioning function. It has good elasticity and flexibility and can absorb and disperse energy through its own deformation when subjected to external impact or vibration, thus playing a role in cushioning and shock absorption.

[0003] Chinese patent CN218885406U discloses a rubber buffer sleeve axial durability test fixture. Its structural components are easy to assemble, and the rubber buffer sleeve can be fixed more firmly. During the durability test, the experimental condition of the product can be observed from the inside of the upper and lower covers and the lower cover plate at any time, so that the overall test effect is higher and better.

[0004] However, in the aforementioned patent, the installation of both the upper and lower cover plates requires the use of four bolts for fixing, which makes installation and disassembly quite cumbersome. When conducting batch tests, the installation and disassembly alone consume a lot of time, thus affecting the test efficiency and increasing the labor intensity of the operators. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for axial durability testing of rubber buffer sleeves, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A fixture for axial durability testing of a rubber buffer sleeve includes a base plate and a rubber buffer sleeve. A fixed arc-shaped seat is mounted on one side of the upper surface of the base plate, and a movable arc-shaped seat is mounted on the other side of the upper surface of the base plate via a translation mechanism. The fixed arc-shaped seat and the movable arc-shaped seat combine to form a circular through groove that matches the diameter of the rubber buffer sleeve. Arc-shaped baffles are mounted on the upper and lower sides of both the fixed and movable arc-shaped seats. A sleeve is provided inside the rubber buffer sleeve, and an inner post is inserted inside the sleeve. An end is mounted on the bottom of the inner post, and a nut is mounted on the outer surface of the inner post near its upper end.

[0008] It can be seen that the rubber buffer sleeve can be disassembled and assembled by moving the movable arc seat through the translation mechanism. The arc baffle, fixed arc seat and movable arc seat are integrated structures, which do not require separate installation by bolts. This enables the rapid disassembly and assembly of the rubber buffer sleeve, which significantly improves the test efficiency and reduces the labor intensity of the operators.

[0009] Furthermore, the translation mechanism includes a mounting groove formed on the upper surface of the substrate, a sliding plate disposed inside the mounting groove, a rotating shaft passing through and rotatably mounted inside the substrate, and the end of the rotating shaft extending into the mounting groove. The outer surface of the rotating shaft located in the mounting groove has external threads, the inside of the sliding plate has a threaded hole, and the end of the rotating shaft is inserted into the threaded hole and threadedly connected thereto.

[0010] Furthermore, the inner wall of the arc-shaped baffle on the upper surface of the fixed arc-shaped seat is provided with a insertion hole, and the outer surface of the nut is equipped with a insertion rod.

[0011] Furthermore, limit grooves are provided on both inner walls of the mounting groove, and limit sliders are installed on both outer surfaces of the slide plate, with the limit sliders set in the limit grooves.

[0012] Furthermore, a handle is installed at the end of the shaft away from the external thread, and the outer surface of the handle is provided with anti-slip texture.

[0013] Furthermore, support bases are installed on both sides of the bottom of the substrate, and bolt holes are opened on the surface of the support bases.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model places a rubber buffer sleeve inside a fixed arc-shaped seat, and then uses a translation mechanism to drive the movable arc-shaped seat to close with the fixed arc-shaped seat, so that the rubber buffer sleeve is in a circular through groove. At this time, the arc-shaped baffles on the upper and lower sides limit the ends of the rubber buffer sleeve. The arc-shaped baffles, the fixed arc-shaped seat and the movable arc-shaped seat are an integral structure, which does not require separate installation by bolts. This enables quick assembly and disassembly of the rubber buffer sleeve, significantly improves the testing efficiency and reduces the labor intensity of the operators.

[0016] 2. By inserting the insertion rod into the insertion hole, this utility model can limit the angle of the nut, preventing the nut from loosening and turning back during testing, thus ensuring the accuracy of the test data. Attached Figure Description

[0025] Please see Figures 1-4This utility model provides a fixture for axial durability testing of a rubber buffer sleeve, comprising a base plate 1 and a rubber buffer sleeve 6. A fixed arc-shaped seat 2 is installed on one side of the upper surface of the base plate 1, and a movable arc-shaped seat 4 is installed on the other side of the upper surface of the base plate 1 via a translation mechanism 3. The fixed arc-shaped seat 2 and the movable arc-shaped seat 4 combine to form a circular through groove adapted to the diameter of the rubber buffer sleeve 6. Arc-shaped baffles 5 are installed on the upper and lower sides of both the fixed arc-shaped seat 2 and the movable arc-shaped seat 4. A sleeve 7 is provided inside the rubber buffer sleeve 6, and an inner post 8 is inserted inside the sleeve 7. An end 9 is installed at the bottom of the inner post 8, and a nut 10 is installed on the outer surface of the inner post 8 near its upper end.

[0026] In use, insert the inner column 8 into one end of the sleeve 7, then tighten the nut 10 onto the inner column 8. With the help of the end head 9, the rubber buffer sleeve 6 can be fixed onto the inner column 8. Then, place the rubber buffer sleeve 6 inside the fixed arc seat 2, and use the translation mechanism 3 to move the movable arc seat 4 closer to the fixed arc seat 2, so that the rubber buffer sleeve 6 is in the circular through groove formed by the combination of the fixed arc seat 2 and the movable arc seat 4. At this time, the arc baffles 5 on the upper and lower sides limit the ends of the rubber buffer sleeve 6. The arc baffles 5, the fixed arc seat 2, and the movable arc seat 4 are an integral structure, which does not require separate installation by bolts. This enables quick assembly and disassembly of the rubber buffer sleeve 6, significantly improving the test efficiency and reducing the labor intensity of the operators.

[0027] Preferably, the translation mechanism 3 includes a mounting groove 301 formed on the upper surface of the substrate 1, a sliding plate 302 disposed inside the mounting groove 301, a rotating shaft 303 passing through and rotatably mounted inside the substrate 1, and the end of the rotating shaft 303 extending into the mounting groove 301. The outer surface of the rotating shaft 303 located in the mounting groove 301 has an external thread 304, the sliding plate 302 has a threaded hole 305 inside, and the end of the rotating shaft 303 is inserted into the threaded hole 305 and threadedly connected thereto.

[0028] When the rotating shaft 303 is rotated, the inner wall of the mounting groove 301 limits the sliding plate 302. Therefore, under the action of the threaded connection, the sliding plate 302 can be moved in the mounting groove 301, thereby adjusting the distance between the movable arc seat 4 and the fixed arc seat 2.

[0029] Preferably, the inner wall of the arc-shaped baffle 5 on the upper surface of the fixed arc-shaped seat 2 is provided with an insertion hole 11, and the outer surface of the nut 10 is provided with an insertion rod 12.

[0030] When the rubber buffer sleeve 6 is placed inside the fixed arc-shaped seat 2, the insertion rod 12 is aligned with the insertion hole 11 and inserted. Then, the translation mechanism 3 is used to drive the movable arc-shaped seat 4 to close with the fixed arc-shaped seat 2. Since the inner column 8 is clamped and fixed with the upper clamp of the durability equipment, and the angle of the nut 10 is limited, the nut 10 can be prevented from loosening and turning over during the test, thus ensuring the accuracy of the test data.

[0031] Preferably, the inner walls on both sides of the mounting groove 301 are provided with limiting grooves 13, and the outer surfaces on both sides of the slide plate 302 are provided with limiting sliders 14, which are disposed in the limiting grooves 13.

[0032] By setting the limiting groove 13 and the limiting slider 14, the limiting effect of the sliding plate 302 is further improved, so that it can move more smoothly in the mounting groove 301, ensuring the precise combination of the movable arc seat 4 and the fixed arc seat 2.

[0033] Preferably, a handle 15 is installed at the end of the shaft 303 away from the external thread 304, and the outer surface of the handle 15 is provided with anti-slip texture.

[0034] By setting the handle 15, the rotating shaft 303 can be rotated more easily and efficiently, thereby improving the efficiency of disassembling and assembling the rubber buffer sleeve 6.

[0035] Preferably, support bases 16 are installed on both sides of the bottom of the substrate 1, and bolt holes 17 are provided on the surface of the support bases 16.

[0036] The support base 16 can be fixed to the test stand of the durability equipment through the bolt hole 17. Since the support base 16 raises the height of the base plate 1, the handle 15 can be designed to be larger, improving the portability of operation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
