Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a fixture for installing a one-way valve sheet on an automobile filter. Background Art

[0002] The car filter is an engine accessory used to filter impurities or gases. In the car filter, there are generally multiple parts that need to be installed with a one-way valve.

[0003] At present, when installing a one-way valve plate in a part of an automobile filter, a guide needle is usually used to press the one-way valve plate onto a matching part. When press-fitting, the press-fitting head of the guide needle is inserted into the positioning groove 0111 on the positioning column 011 on the one-way valve plate 01, and the positioning column 011 on the one-way valve plate 01 is press-fitted into the mounting hole on the matching part 02 by the press-fitting head of the guide needle, so that the one-way valve plate 01 is installed on the matching part 02. Figure 1 and 2 However, when the one-way valve plate is installed by the above press-fitting method, the following problems exist:

[0004] During press-fitting, the press-fitting force applied by the press-fitting head of the guide needle is applied to the bottom of the positioning groove 0111 on the one-way valve plate 01. The bottom of the positioning groove 0111 is easily punctured by the press-fitting head of the guide needle, resulting in defective assembled products.

[0005] After the press-fitting is completed, when the press-fitting head of the guide needle withdraws from the positioning groove 0111, the positioning column 011 of the one-way valve plate 01 is easily brought out by the press-fitting head, resulting in product assembly failure and low assembly efficiency.

[0006] From the above, it can be seen that when the one-way valve plate is installed by the above-mentioned press-fitting method, the yield rate of the assembled product is low and the installation efficiency is low. Utility Model Content

[0007] In order to improve the assembly quality and installation efficiency of the one-way valve plate, the utility model proposes a one-way valve plate assembly jig, the one-way valve plate installation jig includes a press-fitting cylinder and a guide needle, the guide needle is installed in the installation groove in the press-fitting cylinder, and the press-fitting needle head on the guide needle extends from the telescopic hole on the bottom of the press-fitting cylinder and can telescopically move in the telescopic hole.

[0008] When the one-way valve disc installation jig of the utility model is used to install the one-way valve disc, the press-fitting needle on the guide needle is first pushed by the guide rod to make the press-fitting needle extend from the telescopic hole, thereby installing the one-way valve disc to be installed on the press-fitting needle; then, the positioning column on the one-way valve disc to be installed is aligned with the mounting hole on the matching part, and the bottom of the press-fitting cylinder in the one-way valve disc installation jig of the utility model presses the one-way valve disc to be installed; then, the guide needle is pushed so that the press-fitting needle on the guide needle pushes the positioning column to insert the positioning column into the mounting hole on the matching part, thereby installing the one-way valve disc to be installed on the matching part; then, the bottom of the press-fitting cylinder is used to press the one-way valve disc to be installed, and the press-fitting needle is withdrawn from the positioning groove on the one-way valve disc to be installed by the guide rod in the guide needle, and the bottom of the press-fitting cylinder presses the one-way valve disc to be installed, which can prevent the one-way valve disc to be installed from being brought out by the press-fitting needle when the press-fitting needle is withdrawn, resulting in installation failure. In addition, during installation, by using the press-fitting cylinder and the press-fitting needle of the guide needle to simultaneously apply force to the one-way valve disc to be installed, the force applied by the press-fitting needle to the bottom of the positioning groove on the one-way valve disc to be installed can be reduced, thereby reducing the probability of the bottom of the positioning groove being punctured by the press-fitting needle during the installation process, thereby improving the yield rate of the assembled product formed by assembling the one-way valve disc and the matching parts. It can be seen that the use of the one-way valve disc installation jig of the utility model to install the one-way valve disc on the matching parts can effectively improve the yield rate of the assembled product formed by the assembly, reduce the installation failure rate of the one-way valve disc, and thus improve the installation efficiency of the one-way valve disc.

[0009] Preferably, a rebound member is provided in the installation groove, and a press-fitting member is provided on the guide rod of the guide needle. During press-fitting, the press-fitting member compresses the rebound member and pushes the press-fitting needle to extend out of the telescopic hole; after the press-fitting is completed, the press-fitting member drives the press-fitting needle to retract into the telescopic hole under the rebound push of the rebound member. In this way, after the one-way valve plate is installed, the rebound member can be used to push the press-fitting needle on the guide needle to automatically withdraw, thereby improving the installation efficiency of the one-way valve plate. Further, the rebound member is a reaction spring, and the reaction spring is sleeved on the guide rod of the guide needle; the press-fitting member is a press-fitting column connected in line with the guide rod, the diameter of the press-fitting column is larger than the diameter of the guide rod, and the press-fitting column is pressed on the reaction spring toward the press-fitting surface of the press-fitting needle. In this way, the reaction spring is used as the rebound member, and the selection and installation are simple and convenient, and the manufacturing cost of the jig for installing the one-way valve plate of the utility model can be reduced.

[0010] Preferably, a rebound support platform is provided on the inner wall of the press-fitting cylinder, and when the reaction spring is installed in the press-fitting cylinder, the positioning end of the reaction spring is pressed on the rebound support platform. In this way, the positioning end of the reaction spring can be pressed on the rebound support platform, so a reaction spring with a shorter length can meet the use requirements, thereby reducing the manufacturing or procurement cost of the reaction spring, and further reducing the manufacturing cost of the jig for installing the one-way valve plate of the utility model. Furthermore, the rebound support platform is close to the barrel mouth of the press-fitting cylinder. In this way, when the rebound support platform is formed on the inner wall of the press-fitting cylinder, the processing is simple and convenient, which can reduce the production cost of the jig for installing the one-way valve plate of the utility model.

[0011] Preferably, a cylinder cover is provided at the cylinder mouth of the press-fitting cylinder, so that the cylinder cover can be used to limit the guide needle and the rebound member, so as to prevent the guide needle and the rebound member from falling off from the press-fitting cylinder, affecting the use and even affecting the installation efficiency of the one-way valve sheet.

[0012] Preferably, the guide needle includes a press-fitting head, which is connected to the press-fitting column in a colinear manner, the diameter of the press-fitting head is smaller than the diameter of the press-fitting column, and the press-fitting head extends from the press-fitting through hole on the cylinder cover. In this way, when using the one-way valve installation jig of the utility model to install the one-way valve, it is only necessary to press the press-fitting head to apply pressure to the press-fitting head, thereby driving the guide rod and the press-fitting needle in the guide needle to move through the press-fitting head to complete the installation of the one-way valve, which is simple and convenient to use.

[0018] Next, combine Figures 3 to 5 , the jig for installing the one-way valve plate of the utility model is described in detail.

[0019] like Figures 3 to 5As shown, the jig for installing the one-way valve plate of the utility model comprises a press-fitting cylinder 1 and a guide needle, wherein the guide needle is installed in the installation groove 11 in the press-fitting cylinder 1, and the press-fitting needle head 21 on the guide needle extends from the telescopic hole (not shown in the figure) on the cylinder bottom 12 of the press-fitting cylinder 1 and can telescopically move in the telescopic hole. Preferably, a rebound member 3 is provided in the installation groove 11, and a press-fitting member 23 is provided on the guide rod 22 of the guide needle. During press-fitting, the press-fitting member 23 compresses the rebound member 3 and pushes the press-fitting needle head 21 to extend out of the telescopic hole; after the press-fitting is completed, the press-fitting member 23 drives the press-fitting needle head 21 to retract into the telescopic hole under the push of the rebound member 3. In this way, after the installation of the one-way valve plate 4 is completed, the rebound member 3 can be used to push the press-fitting needle head 21 on the guide needle to automatically withdraw, thereby improving the installation efficiency of the one-way valve plate 4. Preferably, the rebound member 3 is a reaction spring, and the reaction spring is sleeved on the guide rod 22 of the guide needle; the press-fitting member 23 is a press-fitting column connected in line with the guide rod 22, the diameter of the press-fitting column is larger than the diameter of the guide rod 22, and the press-fitting column is pressed on the reaction spring with the press-fitting surface facing the press-fitting needle 21. In this way, the reaction spring is used as the rebound member 3, and the selection and installation are simple and convenient, and the manufacturing cost of the one-way valve plate installation jig of the utility model can be reduced. Preferably, a rebound support platform 13 is provided on the inner wall of the press-fitting cylinder 1, and when the reaction spring is installed in the press-fitting cylinder 1, the positioning end of the reaction spring is pressed on the rebound support platform 13. In this way, the positioning end of the reaction spring can be pressed on the rebound support platform 13, so a reaction spring with a shorter length can meet the use requirements, thereby reducing the manufacturing or procurement cost of the reaction spring, and further reducing the manufacturing cost of the one-way valve plate installation jig of the utility model. Preferably, the rebound support platform 13 is close to the barrel mouth of the press-fitting cylinder 1. In this way, when the rebound support platform 13 is formed on the inner wall of the press-fitting cylinder 1, the processing is simple and convenient, which can reduce the production cost of the jig for installing the one-way valve plate of the utility model. Preferably, a cylinder cover 14 is provided at the cylinder mouth of the press-fitting cylinder 1. In this way, the cylinder cover 14 can be used to limit the guide needle and the rebound member 3 to prevent the guide needle and the rebound member 3 from falling off from the press-fitting cylinder 1, affecting the use, and even affecting the installation efficiency of the one-way valve plate 4. Preferably, the guide needle includes a press-fitting head 24, which is connected to the press-fitting column in a colinear manner, and the diameter of the press-fitting head 24 is smaller than the diameter of the press-fitting column, and the press-fitting head 24 extends from the press-fitting through hole (not shown in the figure) on the cylinder cover 14. In this way, when using the one-way valve installation jig of the utility model to install the one-way valve plate 4, it is only necessary to press the press-fitting head 24 to apply pressure to the press-fitting head 24, thereby driving the guide rod 22 and the press-fitting needle 21 in the guide needle to move through the press-fitting head 24, thereby completing the installation of the one-way valve plate 4, which is simple and convenient to use.

[0020] When the one-way valve disc installation jig of the utility model is used to install the one-way valve disc 4, the press-fitting needle 21 on the guide needle is first pushed by the guide rod to make the press-fitting needle 21 extend from the telescopic hole, thereby installing the one-way valve disc 4 to be installed on the press-fitting needle 21; then, the positioning column 41 on the one-way valve disc 4 to be installed is aligned with the mounting hole (not shown in the figure) on the matching part 5, and the bottom 12 of the press-fitting cylinder 1 in the one-way valve disc installation jig of the utility model is pressed against the one-way valve disc 4 to be installed; then, the guide needle is pushed so that the press-fitting needle 21 on the guide needle pushes The movable positioning column 41 inserts the positioning column 41 into the mounting hole on the matching part 5, so that the one-way valve plate 4 to be installed is installed on the matching part 5; then, the one-way valve plate 4 to be installed is pressed by the bottom 12 of the press-fitting cylinder 1, and the press-fitting needle 21 is withdrawn from the positioning groove (not shown in the figure) on the one-way valve plate 4 to be installed through the guide rod 22 in the guide needle, and the bottom 12 of the press-fitting cylinder 1 presses the one-way valve plate 4 to be installed, which can avoid the one-way valve plate 4 to be installed being carried out by the press-fitting needle 21 when the press-fitting needle 21 is withdrawn, resulting in installation failure. In addition, during installation, by using the press-fitting cylinder 1 and the press-fitting needle 21 of the guide needle to simultaneously apply force to the one-way valve disc 4 to be installed, the force applied by the press-fitting needle 21 to the bottom of the positioning groove on the one-way valve disc 4 to be installed can be reduced, thereby reducing the probability of the bottom of the positioning groove being punctured by the press-fitting needle 21 during the installation process, thereby improving the yield rate of the assembled product formed by assembling the one-way valve disc 4 and the matching part 5. It can be seen that the use of the one-way valve disc installation jig of the utility model to install the one-way valve disc 4 on the matching part 5 can effectively improve the yield rate of the assembled product formed by the assembly, reduce the installation failure rate of the one-way valve disc 4, and thus improve the installation efficiency of the one-way valve disc 4.
