Detailed description of the specific implementation

[0018] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0019] The spring steel plate processing fixture of the embodiment of the present application will be described below with reference to the accompanying drawings.

[0020] As shown Figures 1 - 8 in the figure, the spring steel plate processing fixture of the embodiment of the present application may include: a substrate 1, two U-shaped members 2, a driving mechanism 3, and two fixing mechanisms 4.

[0021] Wherein, the two U-shaped members 2 are symmetrically arranged on the substrate 1. A support portion 21 is provided on the U-shaped member 2. There is a gap 22 between the two U-shaped members 2. The spring steel plate to be processed is placed above the gap 22, and the outer wall of the spring steel plate to be processed abuts against the support portion 21.

[0022] It should be noted that in this embodiment, the U-shaped member 2 is inverted on the substrate 1, and the support portion 21 is located at the corner position of the U-shaped member 2.

[0023] It can be understood that when processing the central hole of the spring steel plate, a drilling machine is used for processing. The metal chips generated by drilling can be temporarily stored inside the gap 22. After processing a batch of spring steel plates, relevant technicians can uniformly process the metal chips in the gap 22.

[0024] The driving mechanism 3 is respectively rotatably connected to the two U-shaped members 2. The driving mechanism 3 is connected to the substrate 1. The driving mechanism 3 is used to pull one end of the fixing mechanism 4 to move.

[0025] The two fixing mechanisms 4 are respectively arranged on the outer sides of the corresponding U-shaped members 2. The fixing mechanism 4 is used to apply a force to the spring steel plate to be processed for fixing. The fixing mechanism 4 includes a first connecting member 41, a second connecting member 42, and a shaft body assembly 43.

[0026] Wherein, one ends of the first connecting member 41 and the second connecting member 42 are respectively pivotally connected to the driving mechanism 3. The other end of the first connecting member 41 is rotatably connected to the shaft body assembly 43. The other end of the second connecting member 42 is movably connected to the shaft body assembly 43. The shaft body assembly 43 abuts against the inner side wall of the spring steel plate to be processed.

[0027] The distance between the center of the gap 22 and the support portion 21 is less than the distance between the shaft body assembly 43 and the support portion 21.

[0028] As a possible case, a tension sensor (not shown in the figure) is provided at the connection between the first connecting member 41 and the second connecting member 42 and the driving mechanism 3. The tension sensor is connected to the control device of the external machine tool. The tension sensor can monitor the force between the spring steel plate and the shaft body assembly 43. When the force between the two reaches a preset value, the driving mechanism 3 stops running, thereby ensuring the reliability of the fixture during use.

[0029] It should be noted that this fixture can be installed on the workbench of an external machine tool (e.g., a drill press), and the external machine tool is used to process the spring steel plate fixed by this fixture.

[0030] Specifically, in heavy-duty vehicles, multiple spring steel plates are generally stacked and used, and the multiple spring steel plates are fixed to each other by means of connecting parts (e.g., bolts). Before that, drilling needs to be carried out at the center of the spring steel plate, and this fixture is used to fix the spring steel plate during the processing.

[0031] First, install this fixture on the workbench of an external drill press. The drill is located above this fixture. With the help of an external hoist, place the spring steel plate to be processed on this fixture, and adjust the spring steel plate to be processed so that its lowest point is located at the middle position of the interval 22. The two shaft body assemblies 43 are located above the spring steel plate to be processed.

[0032] Relevant technicians connect the second connecting part 42 with the shaft body assembly 43, and then start the driving mechanism 3 through the control device of the external drill press. The driving mechanism 3 drives the two fixing mechanisms 4 to move away from each other. The shaft body assembly 43 abuts against the inner wall of the spring steel plate to be processed. The tension sensor monitors the acting force between the spring steel plate to be processed and the shaft body assembly 43. When the acting force between the two reaches the preset value, the driving mechanism 3 stops running. Thus, the fixation of the spring steel plate to be processed is completed.

[0033] When using this fixture to fix the spring steel plate, the distance between the center of the interval 22 and the supporting part 21 is the resistance arm, and the distance between the shaft body assembly 43 and the supporting part 21 is the power arm. The shaft body assembly 43, the supporting part 21 and the center of the interval 22 approximately form a labor-saving lever. The acting force between the shaft body assembly 43 and the spring steel plate is small, and the spring steel plate can obtain a better fixing effect.

[0034] When an external mechanical drilling device drills the middle part of the spring steel plate, the distance between the center of the interval 22 and the supporting part 21 is the power arm, and the distance between the shaft body assembly 43 and the supporting part 21 is the resistance arm. The shaft body assembly 43, the supporting part 21 and the center of the interval 22 approximately form a force-consuming lever, so as to reduce the acting force between the spring steel plate and the fixture and ensure the reliability of this fixture when fixing the spring steel plate.

[0035] After the external drill press finishes processing the spring steel plate, the driving mechanism 3 runs again, the fixing mechanism 4 resets, and relevant technicians separate the second connecting part 42 from the shaft body assembly 43, unload the spring steel plate and replace it with a new spring steel plate to be processed.

[0036] In an embodiment of the present application, as Figure 2 and Figure 3As shown, the shaft assembly 43 includes a tube body 431, two first bearings 432, a pressure rod 433, and a retaining ring 434.

[0037] Among them, the two first bearings 432 are respectively arranged inside the tube body 431. The pressure rod 433 is arranged in an elliptical structure, and the outer wall of the pressure rod 433 abuts against the inner wall of the first bearing 432. The retaining ring 434 is arranged inside the tube body 431. The retaining ring 434 is located on one side of a first bearing 432, and the inner diameter of the retaining ring 434 is greater than the major axis length of the pressure rod 433.

[0038] It should be noted that in this embodiment, the pressure rod 433 is limited by the retaining ring 434, and the first connecting member 41 is limited on the other side of the retaining ring 434. During the use of the fixing mechanism 4, the tube body 431 and the retaining ring 434 will not separate from the pressure rod 433.

[0039] Specifically, during the process of the driving mechanism 3 driving the fixing mechanism 4 to move, the tube body 431 in the shaft assembly 43 rolls on the surface of the spring steel plate. As the acting force between the spring steel plate and the shaft assembly 43 increases, the pressure rod 433 abuts against the inner walls of the two first bearings 432. While ensuring that the tube body 431 continues to roll on the surface of the spring steel plate, the pressure rod 433 is eccentrically arranged.

[0040] It can be understood that the pressure rod 433 is arranged in an elliptical structure, which can reduce the contact area with the first bearing 432, increase the acting force between the two, and increase the stability.

[0041] In addition, compared with the central connection of the first connecting member 41 and the second connecting member 42 to the shaft assembly 43, the center of gravity of the eccentric arrangement of the pressure rod 433 is lower, and the shaft assembly 43 is subjected to the action of a balanced force, thereby increasing the stability of the shaft assembly 43 when fixing the spring steel plate.

[0042] In an embodiment of the present application, as Figure 4 shown, the first connecting member 41 includes a first connecting plate 411 and a connecting shaft 412.

[0043] Among them, one end of the first connecting plate 411 is pivotally connected to the driving mechanism 3, the other end of the first connecting plate 411 is connected to the connecting shaft 412, the connecting shaft 412 penetrates through the first connecting plate 411, and the connecting shaft 412 is rotatably connected to the pressure rod 433.

[0044] It can be understood that the connecting shaft 412 penetrates through the first connecting plate 411, which can increase the fastening of the connection between the connecting shaft 412 and the first connecting plate 411.

[0045] In an embodiment of the present application, as Figure 4 shown, the second connecting member 42 includes a plug rod 422 and a second connecting plate 423.

[0046] Wherein, one end of the second connecting plate 423 is pivotally connected to the driving mechanism 3, the inserting rod 422 penetrates through the second connecting plate 423, the inserting rod 422 is movably connected to the second connecting plate 423, a slot 421 is formed at one end of the pressing rod 433, and the inserting rod 422 is inserted into the interior of the slot 421.

[0047] It should be noted that in the above embodiment, the inserting rod 422 is movably connected to the second connecting plate 423, and the inserting rod 422 can slide and rotate relative to the second connecting plate 423. A second bearing (not shown in the figure) is arranged on the second connecting plate 423, and the inserting rod 422 is slidably connected to the inner ring of the second bearing.

[0048] It can be understood that setting the first connecting member 41 and the second connecting member 42 can ensure the unity when the driving mechanism 3 drives the shaft body assembly 43 to move, ensure the balanced force at both ends of the shaft body assembly 43, and thus extend the service life of this fixture.

[0049] In an embodiment of the present application, as Figure 5 shown, the driving mechanism 3 includes two first lead screws 31, a plurality of connecting blocks 32, a transmission member 33 and a driving device 34.

[0050] Wherein, the two first lead screws 31 are respectively rotatably connected to the two U-shaped members 2, the plurality of connecting blocks 32 are respectively threadedly connected to the two first lead screws 31, the first connecting plate 411 and the second connecting plate 423 are respectively pivotally connected to the corresponding connecting blocks 32, the transmission member 33 is respectively connected to the two first lead screws 31, the transmission member 33 is connected to the output shaft of the driving device 34, and the driving device 34 is fixed on the substrate 1.

[0051] It should be noted that the transmission member 33 described in this embodiment may include a plurality of gears and a toothed chain.

[0052] Specifically, during the operation of the driving mechanism 3, the driving device 34 drives the transmission member 33 to rotate, the transmission member 33 drives the two first lead screws 31 to rotate, the first lead screws 31 are threadedly connected to the connecting blocks 32, thereby pushing the connecting blocks 32 to move, and the connecting blocks 32 drive the fixing mechanism 4 to fix the spring steel plate.

[0053] In an embodiment of the present application, as Figures 4 - 6 shown, an auxiliary support member 5 is arranged on one side of the first connecting member 41, and the auxiliary support member 5 includes a support plate 51, a hinge member 52 and a return spring 53.

[0054] Wherein, the support plate 51 is arranged on one connecting block 32, one end of the hinge member 52 is connected to the support plate 51, the other end of the hinge member 52 is connected to the first connecting member 41, and the return spring 53 is connected to the hinge member 52.

[0055] It can be understood that arranging the auxiliary support member 5 on one side of the first connecting member 41 can keep the shaft body assembly 43 lifted after unloading the processed spring steel plate, thus facilitating the placement of the next spring steel plate to be processed.

[0056] In an embodiment of the present application, as Figure 1 、 Figure 7 and Figure 8 shown, an adjustment assembly 6 is arranged on the U-shaped member 2. The adjustment assembly 6 includes a plate body 62, a second screw 63 and a knob 64.

[0057] Among them, a groove 61 is formed on one side of the U-shaped member 2. The plate body 62 is inserted into the inside of the groove 61. One end of the second screw 63 is threadedly connected to the plate body 62. The second screw 63 is rotatably connected to the U-shaped member 2. The knob 64 is arranged on the other end of the second screw 63.

[0058] It can be understood that after the specification of the spring steel plate to be processed changes, that is, the distance between the shaft body assembly 43 and the support portion 21 changes, the relevant technicians change the position of the support portion 21 through the adjustment assembly 6 so that the spring steel plate contacts the plate body 62.

[0059] The relevant technicians rotate the knob 64, and the second screw 63 rotates, thereby pushing the plate body 62 to move inside the groove 61, so that the support portion 21 is transferred to the plate body 62, thereby changing the distance between the support portion 21 and the center of the interval 22, so as to ensure that this fixture can follow the above lever principle when processing various spring steel plates.

[0060] In an embodiment of the present application, as Figure 3 shown, a magnet 71 is arranged at the bottom of the slot 421.

[0061] It can be understood that the insertion rod 422 can be a metal structure. The magnet 71 can fix the insertion rod 422 inside the slot 421. When fixing the spring steel plate and processing the spring steel plate, the insertion rod 422 can be prevented from disengaging from the slot 421. When unloading, the relevant technicians apply force to pull the insertion rod 422, and the insertion rod 422 can disengage from the slot 421, which is convenient to use.

[0062] In an embodiment of the present application, as Figure 2 shown, two grooves 81 are symmetrically arranged on the substrate 1, and a positioning through groove 82 is formed at the bottom of the groove 81.

[0063] It can be understood that arranging the groove 81 and the positioning through groove 82 on the substrate 1 facilitates the relevant technicians to install this fixture on the workbench of an external machine tool by using fixing members (such as fastening bolts). The length of the positioning through groove 82 is relatively long, so that this fixture can be installed on the workbenches of various models of machine tools.

[0064] In summary, for the spring steel plate processing fixture according to the embodiment of the present application, the driving mechanism drives the two fixing mechanisms to move, and the shaft body assembly abuts against the spring steel plate. A lever structure is formed by the shaft body assembly, the supporting part, and the drilling processing position (interval center). The supporting part can be regarded as the fulcrum, and the distances between the shaft body assembly and the supporting part and between the supporting part and the drilling processing position (interval center) can be regarded as the force arms. This structure is approximately a labor-saving lever when fixing the spring steel plate, and is approximately a labor-consuming lever when the mechanical equipment processes the spring steel plate, thereby reducing the acting force between the spring steel plate and the fixture and ensuring the reliability of the fixture when fixing the spring steel plate.
