Description

Technical Field

[0001] This application relates to the field of tensile testing of through-hole sleeves, and more particularly to a tensile testing fixture and tensile testing machine for through-hole sleeves. Background Technology

[0002] Through-hole sleeves are common automotive parts, serving to prevent friction between the wiring harness and the sharp edges of the recessed slot, thus protecting the wiring harness. After production, the through-hole sleeves undergo a tensile test using a stretching machine.

[0003] In related technologies, a tensile testing machine includes a machine body and a tensile testing fixture. The tensile testing fixture includes a mounting base and sheet metal. The lower end of the mounting base is fixedly connected to the machine body, and the sheet metal is welded and fixed to the upper end of the mounting base. During testing, the through-hole sleeve to be tested is installed on the sheet metal, and then the machine body is started to perform a tensile test on the through-hole sleeve.

[0004] However, in practical applications, since one type of sheet metal is adapted to one type of through-hole sleeve, the tensile testing fixture can only be used for one type of through-hole sleeve, resulting in poor applicability, and therefore needs to be improved. Utility Model Content

[0005] In order to improve the applicability of tensile testing fixtures, in a first aspect, this application provides a tensile testing fixture for through-hole sleeves.

[0006] The tensile testing fixture for through-hole sleeves provided in this application adopts the following technical solution:

[0007] A tensile testing fixture for a through-hole sleeve includes a mounting plate, sheet metal, and a mounting base; the mounting plate has a through clearance groove in the vertical direction, and a through insertion groove is formed on one side of the mounting plate, the insertion groove communicating with the clearance groove, and the sheet metal is inserted into the insertion groove; the upper end of the mounting base is located at the lower end of the mounting plate, and the lower end of the mounting base is mounted on the body of the tensile testing machine.

[0008] By adopting the above technical solution, in practical applications, the sheet metal is inserted into the insertion slot, and the lower end of the mounting base is installed on the body of the tensile testing machine to realize the overall installation of the tensile testing fixture. Then, the through-hole sleeve is installed on the sheet metal and the machine is started to work, so as to realize the tensile test of the through-hole sleeve. In this way, the sheet metal inserted into the insertion slot can be removed, and then sheet metal adapted to different through-hole sleeves can be inserted into the insertion slot, which makes it easy to replace different sheet metals to be suitable for different through-hole sleeves, thereby improving the applicability of the tensile testing fixture.

[0009] Preferably, the mounting base includes a mounting post and a plurality of connecting rods, the plurality of connecting rods being evenly spaced along the circumference of the mounting plate, and one end of each connecting rod being located at the lower end of the mounting plate and the other end being located at the upper end of the mounting post.

[0010] By adopting the above technical solution, and by setting up mounting posts and multiple connecting rods, a certain amount of open space is created between the lower end of the mounting plate and the mounting base, so as to facilitate the installation of the through-hole sleeve.

[0011] Preferably, the lower end of the mounting post is provided with external threads.

[0012] By adopting the above technical solution and setting external threads, it is easy to install the mounting column on the machine base.

[0013] Preferably, the mounting plate has chamfers on both sides at one end of the insertion slot.

[0014] By adopting the above technical solution, a chamfer is set to facilitate the insertion of sheet metal into the insertion groove.

[0015] Preferably, the tensile testing fixture further includes a limiting strip, which is disposed at one end of the insertion slot, and one end of the sheet metal abuts against the limiting strip.

[0016] By adopting the above technical solution and setting a limit strip, one end of the sheet metal abuts against the limit strip to achieve the positioning and installation of the sheet metal, thereby improving the accuracy of the through-hole sleeve tensile test.

[0017] Preferably, the tensile testing fixture further includes an abutment rod, which is slidably connected to the limiting strip.

[0018] By adopting the above technical solution, by setting an abutment rod and sliding the abutment rod, the abutment rod slides into the insertion groove and abuts against the sheet metal, so as to push out one end of the sheet metal, so as to facilitate the sheet metal from the insertion groove.

[0019] Preferably, the tensile testing fixture further includes a spring, one end of which is disposed on the mounting plate and the other end of which is disposed on the abutment rod, so as to drive the abutment rod away from the limiting strip.

[0020] By adopting the above technical solution and setting a spring, the abutment rod can be reset, which facilitates the next sheet metal to be inserted into the insertion slot.

[0021] Secondly, this application provides a stretching machine.

[0022] The stretching machine provided in this application adopts the following technical solution:

[0023] A tensile testing machine, comprising the tensile testing fixture described above.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By removing the sheet metal inserted into the insertion slot and then inserting the sheet metal adapted to different through-hole sleeves into the insertion slot, it is easy to replace different sheet metals to suit different through-hole sleeves, thereby improving the applicability of the tensile testing fixture.

[0026] 2. By setting mounting posts and multiple connecting rods, a certain amount of open space is created between the lower end of the mounting plate and the mounting base to facilitate the installation of the through-hole sleeve;

[0027] 3. By setting an abutment rod and sliding the abutment rod, the abutment rod slides into the insertion groove and abuts against the sheet metal, so as to push out one end of the sheet metal, so as to facilitate the sheet metal being removed from the insertion groove.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] The following is in conjunction with the appendix Figure 1-4 This application is described in further detail.

[0036] This application discloses a tensile testing fixture for through-hole sheaths.

[0037] Example 1:

[0038] Reference Figure 1 and Figure 2 The tensile testing fixture includes a mounting plate 1, sheet metal 2, and a mounting base 3. The mounting plate 1 is rectangular and has a vertically extending relief groove 11. A through-hole groove 11 is also provided on one side of the mounting plate 1. The through-hole groove 12 is connected to the relief groove 11, and the sheet metal 2 is inserted into the through-hole groove 12. The upper end of the mounting base 3 is fixedly connected to the lower end of the mounting plate 1, and the lower end of the mounting base 3 is fixedly mounted to the body of the tensile testing machine.

[0039] In practical applications, sheet metal 2 is inserted into the insertion slot 12, and the lower end of the mounting base 3 is installed on the body of the tensile testing machine to achieve the overall installation of the tensile testing fixture. Then, the through-hole sleeve is installed on sheet metal 2, and the machine is started to perform tensile testing on the through-hole sleeve. The operator can remove sheet metal 2 from the insertion slot 12 and then insert sheet metal 2 adapted to different through-hole sleeves into the insertion slot 12, facilitating the replacement of different sheet metal 2 pieces to suit different through-hole sleeves, thereby improving the applicability of the tensile testing fixture.

[0040] In some embodiments, the mounting base 3 includes a mounting post 31 and a plurality of connecting rods 32. The mounting post 31 is arranged in a circular column shape. In this embodiment, the connecting rods 32 are circular rods and there are four connecting rods 32. The four connecting rods 32 are evenly spaced along the circumference of the mounting plate 1. At the same time, one end of the connecting rod 32 is welded and fixed to the lower end of the mounting plate 1, and the other end is welded and fixed to the upper end of the mounting post 31, so that there is a hollow part between the mounting plate 1 and the mounting post 31 for the installation of the through hole sleeve, thereby facilitating the installation of the through hole sleeve.

[0041] In some embodiments, the lower end of the mounting post 31 is provided with an external thread 33, and the mounting post 31 is threaded to the machine base through the external thread 33. The structure is simple and easy to operate, so as to fix the mounting post 31 to the machine base, thereby facilitating the installation and fixation of the tensile testing fixture.

[0042] The implementation principle of this embodiment is as follows: In practical application, sheet metal 2 is inserted into the insertion slot 12, and the lower end of the mounting base 3 is installed on the body of the tensile testing machine to achieve the overall installation of the tensile testing fixture. Then, the through-hole sleeve is installed on sheet metal 2 and the machine is started to perform tensile testing on the through-hole sleeve. The operator can remove sheet metal 2 from the insertion slot 12 and then insert sheet metal 2 adapted to different through-hole sleeves into the insertion slot 12, thus facilitating the replacement of different sheet metal 2 to suit different through-hole sleeves, thereby improving the applicability of the tensile testing fixture.

[0043] Example 2:

[0044] Reference Figure 3 The structure of this embodiment is the same as that of embodiment 1. The difference is that the mounting plate 1 has chamfers 13 on both sides of one end of the insertion groove 12. When the sheet metal 2 is inserted into the insertion groove 12, the two sides of one end of the sheet metal 2 abut against the two chamfers 13 respectively. Under the guidance of the chamfers 13, the sheet metal 2 can be inserted into the insertion groove 12.

[0045] Reference Figure 4 In some embodiments, the tensile testing fixture also includes a limiting strip 4, which is fixedly connected to the mounting plate 1 and located at the end of the insertion slot 12 away from the chamfer 13. When the sheet metal 2 is inserted into the insertion slot 12, one end of the sheet metal 2 abuts against the limiting strip 4 to restrict the movement of the sheet metal 2. This enables the positioning of the sheet metal 2 insertion to achieve the positioning and installation of the sheet metal 2, thereby improving the accuracy of the tensile test of the through-hole sleeve.

[0046] In some embodiments, the tensile testing fixture further includes an abutment rod 5, which is a round rod. The abutment rod 5 is perpendicular to the limiting strip 4 and is slidably connected to the limiting strip 4. In practical applications, the sheet metal 2 is fully inserted into the insertion groove 12 to ensure the installation stability of the sheet metal 2. By sliding the abutment rod 5, the abutment rod 5 slides into the insertion groove 12 and abuts against the sheet metal 2 to push out one end of the sheet metal 2. Then, the sheet metal 2 can be pulled out through the pushed-out end of the sheet metal 2 to facilitate the replacement of the sheet metal 2 from the insertion groove 12.

[0047] In some embodiments, the tensile testing fixture further includes a spring 6, one end of which is fixedly connected to one side of the mounting plate 1 and the other end is fixedly connected to the abutment rod 5 to drive the abutment rod 5 away from the limiting strip 4. After the abutment rod 5 slides and the sheet metal 2 is disengaged from the insertion slot 12, the spring 6 drives the abutment rod 5 to slide away from the limiting strip 4 to achieve the reset of the abutment rod 5, so that the abutment rod 5 extends out of the insertion slot 12, thereby facilitating the insertion of the next sheet metal 2 into the insertion slot 12.

[0048] The implementation principle of this embodiment is as follows: In practical applications, the sheet metal 2 is fully inserted into the insertion slot 12 to ensure the installation stability of the sheet metal 2. By sliding the abutment rod 5, the abutment rod 5 slides into the insertion slot 12 and abuts against the sheet metal 2 to push out one end of the sheet metal 2. Then, the sheet metal 2 can be pulled out through the pushed-out end of the sheet metal 2 so as to remove the sheet metal 2 from the insertion slot 12, thereby facilitating the replacement of the sheet metal 2.

[0049] At the same time, the spring 6 can drive the abutment rod 5 to slide away from the limit bar 4, so as to realize the reset of the abutment rod 5, so that the abutment rod 5 extends out of the insertion groove 12, thereby facilitating the insertion of the next sheet metal 2 into the insertion groove 12.

[0050] This application also discloses a stretching machine.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
