Description
Technical Field
[0001] The utility model relates to the technical field of riveting, in particular to an accessory used in conjunction with riveting, specifically a tooling for simultaneously fixing multiple groups of test plates so as to efficiently perform pressure riveting tests. Background Art
[0002] The main function of the automatic riveting machine is to automatically rivet two parts, including the continuous operation process of positioning, drilling, countersinking and riveting. The riveting strength of the automatic riveting machine directly determines the riveting quality. Therefore, before riveting, it is necessary to make two test plates with the same thickness and material as the parts that actually need to be riveted as a set of test plates to cooperate with rivets for riveting test, and then measure and evaluate the shape of the rivets. Then increase or decrease the riveting strength or riveting distance according to the riveting test results, and re-perform the riveting test, measure the shape of the rivets and evaluate them. After multiple riveting tests, the optimal riveting strength of the test plate and the rivet is finally determined. Among them, the evaluation is mainly to observe whether the rivet head is intact, whether there are abnormal marks, whether it is over-compressed, etc. The riveting strength obtained by the riveting test is only valid for specific riveted parts. When the riveted parts or rivets are replaced, the riveting test needs to be re-performed. The press riveting test is a repetitive test. Only one set of test plates is tested each time. Each press riveting test requires reinstalling and leveling the test plates, which makes the entire press riveting test process time-consuming, labor-intensive and inefficient. Utility Model Content

DETAILED DESCRIPTION
[0021] The utility model will be further described below in conjunction with the accompanying drawings.
[0022] See also Figure 1 Figure 2 The utility model comprises an upper frame 1 and a lower frame 2, and both the upper frame 1 and the lower frame 2 are flat plate structures. In order to ensure the self-strength of the upper frame 1 and the lower frame 2, the upper frame 1 and the lower frame 2 are generally made of metal. The upper frame 1 is provided with at least two upper mounting holes 11 for mounting the test plates, and the upper mounting hole 11 is used to mount a test plate in a group of test plates for the pressure riveting test. The upper mounting hole 11 passes through the two plate surfaces of the upper frame 1, so as to realize the placement of the test plate into the upper mounting hole 11 and the removal of the test plate from the upper mounting hole 11 from the overlapping surface of the upper frame 1, and to facilitate the pressure riveting test. In order to prevent the test plate from escaping from the end of the upper mounting hole 11 away from the lower frame 2, an upper limit structure 12 is provided on the side wall of the upper mounting hole 11. For example, the upper limit structure 12 is a step arranged on the side wall of the upper mounting hole 11, and the number of steps is sufficient as long as it can prevent the test plate from escaping from the upper mounting hole 11. The upper limit structure 12 can also be a baffle fixed to the upper frame 1 and located at one end of the upper mounting hole 11 away from the lower frame 2, and the baffle partially blocks the upper mounting hole 11. For example, the upper mounting hole 11 is a rectangular hole, and steps are respectively provided on two opposite side walls of the four side walls of the rectangular hole, or steps are provided on three side walls of the four side walls of the rectangular hole, or steps are provided on all four side walls of the rectangular hole.
[0023] The lower frame 2 and the upper frame 1 have the same shape. Accordingly, the lower frame 2 is provided with at least two lower mounting holes 21 for mounting the test board, and the lower mounting hole 12 is used to mount another test board in a group of test boards for the riveting test. The lower mounting hole 21 passes through the two board surfaces of the lower frame 2, so as to realize the placement of the test board into the lower mounting hole 12 from the overlapping surface of the lower frame 2 and the removal of the test board from the lower mounting hole 12, and to facilitate the riveting test. In order to prevent the test board from escaping from the end of the lower mounting hole 12 away from the upper frame 1, a lower limiting structure 22 is provided on the side wall of the lower mounting hole 21. For example, the lower limiting structure 22 is a step provided on the side wall of the lower mounting hole 12, and the number of steps is sufficient as long as it can prevent the test board from escaping from the lower mounting hole 12. The lower limiting structure 12 can also be a baffle fixed to the lower frame 2 and located at the end of the upper mounting hole 11 away from the lower frame 2, and the baffle partially blocks the lower mounting hole 12. For example, the lower mounting hole 12 is a rectangular hole, and steps are respectively arranged on two opposite side walls of the four side walls of the rectangular hole, or on three side walls of the four side walls of the rectangular hole, or on all four side walls of the rectangular hole.
[0024] After the upper frame 1 and the lower frame 2 are overlapped, each upper mounting hole 11 corresponds to each lower mounting hole 21 one by one. At least one fastener 3 is also provided between the upper frame 1 and the lower frame 2 to fix the upper frame 1 and the lower frame 2 to each other. By loosening or releasing the fastener 3, the upper frame 1 and the lower frame 2 can be separated. In order to simplify the structure of the fastener 3, reduce the processing difficulty, and ensure the fastening effect of the upper frame 1 and the lower frame 2, for example, the fastener 3 is a screw, and the upper frame 1 and the lower frame 2 are respectively provided with corresponding threaded holes; or, the fastener 3 is a bolt and a nut matched therewith, and the upper frame 1 and the lower frame 2 are respectively provided with corresponding through holes. There are generally at least two fasteners 3 to ensure the stability of the upper frame 1 and the lower frame 2 after they are fixed. In order to facilitate the overlap of the upper frame 1 and the lower frame 2 according to the predetermined position, at least one group of positioning structures is also provided between the overlapping panels of the upper frame 1 and the lower frame 2. For example, the positioning structure is provided with a positioning groove 13 for one of the upper frame 1 and the lower frame 2, and a positioning column 23 matched with the positioning groove 13 for the other. See Figures 1 to 4 The upper frame 1 is provided with a positioning groove 13 , and the lower frame 2 is provided with an adaptive positioning column 23 .
[0025] The shapes of the upper mounting holes 11 and the lower mounting holes 12 are adapted to the shape of the test board, that is, the test board can be relatively fixed after being placed in the upper mounting holes 11 and the lower mounting holes 12. The shapes of the upper mounting holes 11 and the lower mounting holes 12 are generally the same as the shapes of the test board, and the upper mounting holes 11 and the lower mounting holes 12 can be any shapes such as polygons, circles, etc. The test board is generally a rectangular plate, so the upper mounting holes 11 and the lower mounting holes 21 are generally rectangular holes, and the sizes of the rectangular holes are consistent and correspond to each other. In order to facilitate the arrangement of the upper mounting holes 11 and the lower mounting holes 21, and also to facilitate the pressure riveting test, the upper mounting holes 11 and the lower mounting holes 21 are arranged in a matrix on the upper frame 1 and the lower frame 2, that is, the upper mounting holes 11 and the lower mounting holes 21 are evenly arranged on the upper frame 1 and the lower frame 2 according to a certain number of rows and columns. For example, see Figure 1 and Figure 2 The upper frame 1 and the lower frame 2 are both in the shape of a field, and the upper frame 1 and the lower frame 2 respectively form four upper mounting holes 11 and four lower mounting holes 21, and the four corners of the rectangular hole are respectively provided with positioning structures, and the four corners of the rectangular hole are respectively provided with fasteners 3, and steps are respectively provided on two opposite side walls of the four side walls of the rectangular hole.
[0026] In order to facilitate observation of whether the test plate is level before the riveting test, a level bubble is set on the plate surface of the upper frame 1 facing away from the lower frame 2, and the plane corresponding to the upper frame 1 is parallel to the plane corresponding to the upper mounting hole 11, and the plane corresponding to the lower frame 2 is parallel to the plane corresponding to the lower mounting hole 21.
[0027] After the upper frame 1 and the lower frame 2 are fixed by the fasteners 3, in order to facilitate the leveling of the upper frame 1 and the lower frame 2, and also to achieve the purpose of adjusting the height between the test board and the supporting surface, at least three leveling mechanisms 5 are set on the board surface of the lower frame 2 facing away from the upper frame 1. A specific leveling mechanism 5 is listed below. Figure 1 and Figure 2 A guide rail 4 is fixedly installed on opposite sides of the lower frame 2. The guide rail 4 is located on the side of the lower frame 2 facing away from the upper frame 1. A slide groove 41 is arranged on the side of the guide rail 4 facing away from the lower frame 2. Two leveling mechanisms 5 are arranged in the slide groove 41 of each guide rail 4. Figure 5 and Figure 6 The leveling mechanism 5 includes a ball 51 that is slidably engaged in the slide groove 41, and the ball 51 is fixedly connected to the threaded tube 52. The ball 51 and the threaded tube 52 can slide along the slide groove 41. The threaded tube 52 has an external thread and an internal thread. The outer side of the threaded tube 52 is threadedly connected to a first locking nut 53. The first locking nut 53 is located outside the slide groove 41. The size of the first locking nut 53 is larger than the width of the slide groove 41. The inside of the threaded tube 52 is threadedly connected to one end of a screw rod 54. A second locking nut 55 is arranged on the outer side of the screw rod 54. The other end of the screw rod 54 is fixedly connected to a disk 56, and the disk 56 plays a supporting role.
[0028] Before the riveting test, unfasten the fasteners 3 to separate the upper frame 1 and the lower frame 2, put one test plate in a group of test plates into the upper mounting hole 11, put another test plate in the group of test plates into the corresponding lower mounting hole 21, and put a group of test plates in the other corresponding upper mounting holes 11 and lower mounting holes 21, and then overlap the upper frame 1 and the lower frame 2 and fix them with the fasteners 3. Under the action of the upper limit structure 12, the lower limit structure 22 and the fasteners 3, the upper frame 1, the lower frame 2 and each group of test plates are locked and formed into a whole, which is the test plate fixture 8. The test plate fixture 8 is used to cooperate with the riveting machine 6 and the dual-axis mobile platform 7 to perform the riveting test, see Figure 7 . The two-axis mobile platform 7 is used to install the test plate fixture 8. The two-axis mobile platform 7 can drive the test plate fixture 8 to move along the X-axis direction and the Y-axis direction on the horizontal plane to meet the movement and positioning of any position within the travel range. Since the riveting machine 6 needs to visually locate the test plate fixture 8 to determine the position of the test plate, it is best to set a visual positioning structure on the board surface of the upper frame 1 facing away from the lower frame 2. For example, the first mounting hole 11 is a rectangular hole, and fasteners 3 are respectively arranged at the four corners of the rectangular hole. The fastener 3 is located at one end of the board surface of the upper frame 1 facing away from the lower frame 2, which is a cylindrical end. The riveting machine 6 performs visual positioning through the cylindrical end. After the test plate fixture 8 is installed, the riveting machine 6 can continuously perform riveting tests on multiple groups of test plates. The riveting strength of each group of test plates is different, so that multiple riveting strengths can be tested at one time.
