[0002] The tooling is a set of mechanical structures used to position and clamp the fixture to meet the requirements of fixture processing or production process. In addition to meeting the basic positioning and clamping functions, the press-fitting system also requires the tooling to have a certain rigidity and strength to prevent deformation during the press-fitting process that may cause the fixture to be scrapped.
[0003] In the press-fitting industry, each process of the product needs to be customized and designed with corresponding tooling, and each press-fitting process has a single action and low efficiency. Therefore, it is necessary to develop a turntable press-fitting system that can not only ensure the rigidity and strength during the press-fitting process but also greatly improve the work efficiency to solve this problem.
[0004] In the related art, the traditional press-fitting system is generally a single-station mode, that is, one set of press-fitting system corresponds to one set of tooling, so as to ensure the stability during the press-fitting process. However, this production mode cannot meet the company's growing production needs. If the traditional single-station mode is changed to a turntable transportation mode, the production efficiency can be greatly improved. However, ordinary turntables will bring problems such as low strength, poor precision, and inability to overcome the offset load generated during the press-fitting process. In order to solve this problem, an up and down floating tooling applied to a turntable press-fitting system is proposed. On the premise of meeting the stiffness and strength requirements, it can also produce continuously, greatly improving work efficiency. Utility Model Content

DETAILED DESCRIPTION
[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0031] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.
[0032] Figure 1 It is a structural schematic diagram of an up-and-down floating tooling applied to a turntable press-fitting system provided by an embodiment of the present application, including an outermost fixing member 1, a positioning member 2 arranged in the fixing member 1, and a connecting member 3 arranged below the positioning member 2. The connecting member 3 is connected to the upper positioning member 2 through an elastic member 4. The positioning member 2 is provided with a mounting hole, and the jig 8 is located in the mounting hole. Due to the action of the elastic member 4, the positioning member 2 and the fixing member 1 are pressed together up and down under the action of an external mechanical device in the press-fitting state. Specifically, a lifting device is provided at the lower part to lift the jig upward from the lower part, drive the elastic member 4 to compress, and the upper press-fitting cylinder presses the jig downward to achieve the joint action of the upper and lower pressing. In the non-press-fitting state or separation state, the positioning member 2 and the connecting member 3 are not subjected to force, and the fixing member 1 will be separated from the positioning member 2 under the action of the elastic member 4, so as to achieve efficient replacement operation.
[0033] Figure 2 This is a schematic diagram of the scenario of applying the up-and-down floating tooling to the turntable press-fitting system. A rotating disk 9 is set up, and a number of press-fitting positions are evenly opened on the outer ring of the rotating disk. The up-and-down floating tooling is placed in the press-fitting positions. The number of tooling is determined by the size of the tooling and the turntable structure, for example Figure 2 Six workstations are arranged in the middle, and each workstation is spaced 60 degrees apart. A press cylinder 10 and a lower lifting mechanism 110 are arranged above and below the upper and lower floating tooling, respectively. In the press state, the press cylinder 10 presses the fixture 8 downward.
[0034] Figure 3 It is a top view of the up and down floating tooling. In a possible implementation, the structures such as the fixing member 1, the positioning member 2 and the connecting member 3 are all designed as annular structures. Correspondingly, the fixture 8 is also annular and is arranged on the positioning member 2.
[0035] Figure 4 yes Figure 3 The cross-sectional view of the floating tooling in the middle from the AA perspective. Figure 5 yes Figure 4 Exploded view of the fixing member and the positioning member. In some embodiments, the fixing member 1 is designed with inner and outer walls of different heights, that is, the height of the inner ring wall 11 is lower than the height of the outer ring wall, and an annular groove 12 is formed between the inner ring wall 11 and the outer ring wall. The positioning member 2 is inserted into the annular groove 12 and the inner ring space of the fixing member 1 in a press-fit state, and is supported by the inner ring wall 11.
[0036] Considering that there may be liquid on the surface of the fixture, an annular first sealing groove 13 is opened at the bottom of the fixing part 1, and a first O-ring is installed in the first sealing groove 13 to prevent the liquid on the surface of the fixture from leaking from the gap between the fixing part 1 and the turntable during the rotation process. The inner ring wall is also uniformly provided with through nail holes 14 for positioning the connecting part 3 and the fixing part 1.
[0037] The annular positioning member 2 includes a first ring arm 21 and a second ring arm 22. The first ring arm 21 is located at the outside and has a smaller arm length than the second ring arm 22. Extension holes 23 matching the nail holes 14 are evenly opened on the ring arms between the first ring arm 21 and the second ring arm 22. In the press-fit state, the connecting member 3 passes through the nail holes 14 and extends into the extension holes 23. An annular extension section 24 is provided at the end of the second ring arm 22, and an annular fixing groove 25 is opened on the outside of the extension section 24, and the connecting member 3 is set in the annular fixing groove 25.
[0038] The top height of the second ring arm 22 is lower than the top height of the first ring arm 21, and a second sealing groove 26 is provided at the top connection of the two ring arms, and a second O-type sealing ring 6 is provided in the second sealing groove 26. The second sealing ring in the sealing groove can prevent liquid from leaking from the gap between the positioning member 2 and the fixture 8.
[0039] Figure 6 yes Figure 4 The enlarged view of point B in the middle. Figure 7 It is a schematic diagram of the separation of the upper and lower floating tooling. The shape of the connecting piece is the same as that of the positioning piece and the fixing piece, and is also a ring structure. Figure 7 In the figure, the connecting member 3 includes an annular connecting ring 31 and a shoulder screw 7 installed on the connecting ring 31. The connecting ring 31 is evenly provided with mounting holes, and the shoulder screw 7 is inserted in series. The shoulder screw 7 is inserted upward into the nail hole 14. The shoulder screw 7 corresponds to the extension hole 23 of the nail hole 14 upward, and will pass through the extension hole 23 of the nail hole 14 upward in the compressed state. The elastic member 4 is sleeved on the shoulder screw 7 under the positioning member 2, and the upper end is fixed in the nail hole 14. In the embodiment of the present application, the elastic member can be any structure that has elastic deformation and can be restored, such as a spring structure. During the downward pressing process of the positioning member, the spring is compressed. After the upper and lower lifting mechanisms are removed, the spring in the nail hole is restored to separate the fixing member and the positioning member.
[0040] It is particularly noted that the distance between the second ring arm and the first ring arm should meet the width of the shoulder screw passing upward, and in the pressed state, the first ring arm is lowered into the annular groove, and the second ring arm is lowered into the inner ring of the fixing part, close to the inner ring wall, to reduce vibration between the parts.
[0041] Figure 8 and Fig. 9 They are schematic diagrams of the press-fitting system separation and press-fitting states. In the initial state, the lower lifting mechanism descends below the lowest surface of the floating tooling, and the upper press-fitting cylinder rises above the fixture. At this time, the turntable can rotate arbitrarily.
[0042] In the press-fitting state, the lower jacking mechanism rises, the floating fixture spring is compressed, the floating fixture is raised to the height of the working surface, and the upper press-fitting cylinder descends to press-fit the fixture. At this time, the lower jacking mechanism is stressed, and the turntable is not stressed. After the press-fitting is completed, the lower jacking mechanism descends, the upper press-fitting cylinder or jacking mechanism rises, the floating fixture returns to its original state, the turntable rotates 60 degrees, and the next fixture is pressed, and this is repeated.
[0043] To summarize, the tooling is set up as an upper and lower separated structure, the jig is carried by the positioning part, and the press-fitting from bottom to top is realized through the connecting part and the elastic part, while the outer fixing part supports the upper positioning part and the lower connecting part to realize two-way press-fitting; the elastic part is arranged on the connecting part to automatically separate the positioning part from the fixing part after the press-fitting is completed.
[0044] In addition, this structure can improve the traditional single-tool pressing mode into a turntable-operated multi-tool transfer mode. While meeting the rigidity and strength requirements, it can also enable continuous production, greatly improving work efficiency.
