Description
Technical Field
[0001] This utility model relates to the field of cold welding mechanism in capacitor manufacturing equipment, and in particular to a cold welding module. Background Technology
[0002] The capacitor cold soldering mechanism on the market includes a driving device and a cold soldering device. The driving device drives the cold soldering device to press down, thereby realizing cold soldering. The existing cold welding device includes an eccentric shaft, a pressure roller, an adjusting assembly, an elastic reset component, and a slider. The pressure roller is mounted on the eccentric shaft, and the slider is positioned below the pressure roller, allowing it to move up and down. The adjusting assembly is located between the pressure roller and the slider, and is used to adjust the relative distance between the slider and the eccentric shaft. The elastic reset component is used to push the slider back to its original position. The adjusting assembly includes an adjusting bolt and a fastening nut fitted over the adjusting bolt. The upper end of the adjusting bolt abuts against the circumferential wall of the pressure roller, and the lower end of the adjusting bolt is threaded to the slider. By rotating the adjusting bolt, the relative distance between the slider and the eccentric shaft is adjusted, thereby adjusting the gap between the cold welding flat mold and the cold welding toothed mold during mold closing. After adjusting the gap, the fastening nut is tightened. Although this device can adjust the gap, it lacks a design that visually displays the fine-tuning dimensions, making it impossible to intuitively see the fine-tuning size. When adjusting the gap, one can only rely on feeling to rotate and adjust the gap size, which is not conducive to adjustment, prone to errors, and makes it difficult to guarantee adjustment accuracy.
[0003] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a cold welding module that allows for intuitive visualization of the fine-tuning dimensions, making adjustment more convenient, reducing errors, and improving adjustment accuracy.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cold welding module includes an eccentric shaft, a pressure roller, an adjusting component, an elastic reset component, and a slider. The pressure roller is mounted on the eccentric shaft, and the slider is movable up and down below the pressure roller. The adjusting component is positioned between the pressure roller and the slider and is used to adjust the relative distance between the slider and the eccentric shaft. The elastic reset component is used to cause the slider to reset upwards. The module also includes a fine-tuning screw, a clamping plate, and a digital display. The fine-tuning screw is rotatable; rotating the fine-tuning screw causes the adjusting component to move up and down. The digital display records and displays the number of rotations of the fine-tuning screw, and the clamping plate is used to lock or release the fine-tuning screw.
[0007] As a preferred embodiment, the adjustment assembly includes a fine-tuning block and a fine-tuning slider. The fine-tuning slider is laterally movable and abuts against the upper end of the slider. The upper and lower ends of the fine-tuning block abut against the peripheral sidewall of the pressure roller and the upper end of the fine-tuning slider, respectively. The fine-tuning block and the fine-tuning slider are engaged by an inclined plane. Rotating the fine-tuning screw causes the fine-tuning slider to move laterally, and the fine-tuning slider causes the fine-tuning block to move up and down via the inclined plane.
[0008] As a preferred embodiment, one end of the fine-tuning screw passes through the fine-tuning slider, and the other end passes through the clamping plate and the digital display in sequence;
[0009] As a preferred embodiment, the adjustment assembly further includes a fine-tuning housing and a first bearing seat and a second bearing seat respectively installed at both ends of the fine-tuning housing. The first bearing seat and the second bearing seat are respectively provided with a first bearing and a second bearing. One end of the fine-tuning screw is connected to the first bearing, and the other end of the fine-tuning screw passes through the second bearing and extends out of the second bearing seat. The clamping plate is installed on the side of the second bearing seat away from the first bearing seat. The fine-tuning block and the fine-tuning slider are both located inside the fine-tuning housing. The upper end of the fine-tuning block extends out of the upper end of the fine-tuning housing, and the lower end of the fine-tuning slider protrudes from the lower end of the fine-tuning housing. The slider is located below the fine-tuning housing.
[0010] As a preferred embodiment, the clamping plate has a first through groove extending laterally, a second through groove extending vertically, a through hole for a fine-tuning screw to pass through, and a locking hole for installing a locking screw. The first through groove, the second through groove, and the through hole all extend along the thickness direction of the clamping plate, and the locking hole extends along the length direction of the clamping plate. The first through groove and the second through groove are respectively connected to the through hole. The first through groove is located above the second through groove. The second through groove passes through the lower end of the clamping plate, and the locking hole passes through the second through groove. The locking hole is fitted with a locking screw.
[0011] As a preferred embodiment, the system also includes a support frame, which is a hollow structure. The slider moves up and down within the support frame, and the elastic reset element is a reset spring, which is embedded within the slider.
[0012] As a preferred embodiment, the slider has a receiving groove on its side, and the inner side of the support frame has a locking spring block. The spring block extends into the lower end of the receiving groove, and the reset spring is disposed in the receiving groove. The lower end of the reset spring abuts against the spring block, and the upper end of the reset spring abuts against the inner upper wall of the receiving groove.
[0013] As a preferred embodiment, the lower end of the slider is provided with a mounting position for mounting a cold welding flat mold.
[0014] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly utilizes a combination design of a fine-tuning screw and a digital display. Rotating the fine-tuning screw causes the adjustment component to move up and down. The digital display records and displays the number of rotations of the fine-tuning screw, allowing for a direct view of the fine-tuning dimension, which is more conducive to adjustment, less prone to errors, and improves adjustment accuracy. Furthermore, by setting a clamping plate to lock or release the fine-tuning screw, it is possible to lock the fine-tuning screw after adjustment, thus preventing secondary changes in the angle of the fine-tuning screw and ensuring that the adjusted gap remains unchanged. Additionally, by recording and displaying the number of rotations of the fine-tuning screw on the digital display, each digit increment represents the number of rotations of the fine-tuning screw. This allows for setting how much adjustment distance each digit increment represents, quantifying the fine-tuning dimension.

[0039] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inner", and "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0040] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of the cold welding module provided in an embodiment of this utility model.
[0041] This cold welding module includes an eccentric shaft 10, a pressure roller 20, an adjusting component 30, an elastic reset component, and a slider 50. The pressure roller 20 is mounted on the eccentric shaft 10, and the slider 50 is positioned below the pressure roller 20 and can move up and down. The adjusting component 30 is located between the pressure roller 20 and the slider 50, and is used to adjust the relative distance between the slider 50 and the eccentric shaft 10. The elastic reset component is used to cause the slider 50 to return to its original position, that is, to cause the slider 50 to always push the adjusting component 30 upward so that the upper end of the adjusting component 30 always abuts against the pressure roller 20. It also includes a fine-tuning screw 60, a clamping plate 70, and a digital display 80. The fine-tuning screw 60 is rotatable; rotating the fine-tuning screw 60 causes the adjusting assembly 30 to move up and down; the digital display 80 records and displays the number of rotations of the fine-tuning screw 60; the clamping plate 70 is used to lock or release the fine-tuning screw 60. This allows for a direct visual observation of the fine-tuning dimensions, facilitating adjustment, reducing errors, and improving adjustment accuracy. Furthermore, by setting the clamping plate 70 to lock or release the fine-tuning screw 60, it ensures that after adjustment, the screw 60 is locked in place, preventing secondary changes in the angle of the fine-tuning screw 60 and ensuring that the adjusted gap remains unchanged.
[0042] The adjustment component 30 includes a fine-tuning block 31 and a fine-tuning slider 32. The fine-tuning slider 32 is laterally movable (in this embodiment, the fine-tuning slider 32 moves left and right) and abuts against the upper end of the slider 50. The upper and lower ends of the fine-tuning block 31 abut against the peripheral sidewall of the pressure roller 20 and the upper end of the fine-tuning slider 32, respectively. The fine-tuning block 31 and the fine-tuning slider 32 are engaged by an inclined surface 33. One end of the fine-tuning screw 60 passes through the fine-tuning slider 32, and the other end passes through the clamping plate 70 and the digital display 80 in sequence. When the fine-tuning screw 60 is rotated, the fine-tuning screw 60 drives the fine-tuning slider 32 to move laterally. The fine-tuning slider 32 drives the fine-tuning block 31 to move up and down through the inclined surface 33, so as to change the relative distance between the slider 50 and the eccentric shaft 10, thereby adjusting the gap between the cold-welded flat mold 102 and the cold-welded toothed mold 104 when the mold is closed.
[0043] In this embodiment, the relative distance between the slider 50 and the eccentric shaft 10 changes by 0.1 mm (the actual change in the relative distance between the slider 50 and the eccentric shaft 10 is 0.1 mm, which can be changed by altering the angle of the inclined plane 33). The digital display 80 records the number of rotations of the fine-tuning screw 60. Each digit on the digital display 80 represents 1 / 10 of a rotation of the fine-tuning screw 60 (in practice, a single digit could also represent other rotations of the fine-tuning screw 60; 1 / 10 of a rotation is used in this embodiment), thus quantifying the fine-tuning dimension. Since each increment of the digital display 80 corresponds to an adjustment distance of 0.01mm, the advantage of this structure is that it quantifies the adjustment of the mold closing gap between the cold-welded flat mold 102 and the cold-welded toothed mold 104. After adjustment, the clamping plate 70 holds the fine-tuning screw 60 in place, preventing a secondary change in the angle of the fine-tuning screw 60. Furthermore, in this embodiment, the ratio of the change in the mold closing gap between the cold-welded flat mold 102 and the cold-welded toothed mold 104 to the left and right movement of the fine-tuning slider 32 is 1:20, thereby reducing the gap error between the threads of the fine-tuning slider 32 and the fine-tuning screw 60 by 20 times.
[0044] The adjustment assembly 30 further includes a fine-tuning housing 34 and a first bearing seat 35 and a second bearing seat 36 respectively installed at both ends of the fine-tuning housing 34. The first bearing seat 35 and the second bearing seat 36 are respectively provided with a first bearing 37 and a second bearing 38. One end of the fine-tuning screw 60 is connected to the first bearing 37, and the other end of the fine-tuning screw 60 passes through the second bearing 38 and extends out of the second bearing seat 36. The clamping plate 70 is installed on the side of the second bearing seat 36 away from the first bearing seat 35. The fine-tuning block 31 and the fine-tuning slider 32 are both located inside the fine-tuning housing 34. The upper end of the fine-tuning block 31 extends out of the upper end of the fine-tuning housing 34, and the lower end of the fine-tuning slider 32 is exposed at the lower end of the fine-tuning housing 34. The slider 50 is located below the fine-tuning housing 34.
[0045] The clamping plate 70 has a first through groove 71 extending laterally, a second through groove 72 extending vertically, a through hole 73 for the fine-tuning screw 60 to pass through, and a locking hole 74 for installing a locking screw. The first through groove 71, the second through groove 72, and the through hole 73 all extend along the thickness direction of the clamping plate 70, and the locking hole 74 extends along the length direction of the clamping plate 70. The first through groove 71 and the second through groove 72 are respectively connected to the through hole 73. The first through groove 71 is located above the second through groove 72. The second through groove 72 passes through the lower end of the clamping plate 70, and the locking hole 74 passes through the second through groove 72. A locking screw (not shown in the figure) is installed in the locking hole 74. Thus, when the locking screw is tightened, the locking screw can pull the two opposite inner sidewalls of the second through groove 72 closer together to clamp the fine-tuning screw 60.
[0046] The cold welding module also includes a support frame 90, which is a hollow structure. The slider 50 moves up and down within the support frame 90. The elastic reset element is a reset spring 40, which is embedded in the slider 50. Specifically, in this embodiment, a receiving groove 51 is provided on the side of the slider 50. A spring pressure block 91 is locked on the inner side of the support frame 90. The spring pressure block 91 extends into the lower end of the receiving groove 51. The reset spring 40 is disposed in the receiving groove 51. The lower end of the reset spring 40 abuts against the spring pressure block 91, and the upper end of the reset spring 40 abuts against the inner upper wall of the receiving groove 51.
[0047] The support frame 90 includes a main body 92 and a cover plate 93 that is detachably connected to the main body 92 by screws. The cover plate 93 and the main body 92 form the hollow structure described above. Two receiving grooves 51 are provided on both opposite sides of the slider 50. Correspondingly, two spring blocks 91 are locked on the inner side of the cover plate 93 and the inner side of the main body 92.
[0048] The lower end of the slider 50 is provided with a mounting position 52 for mounting the cold welding flat mold 102. The mounting position 52 has a plurality of mounting holes 521. The mounting holes 521 at the bottom of the mounting position 52 are connected to the upper mold base 101 by screws. The lower end of the upper mold base 101 is connected to the cold welding flat mold 102. Both sides of the upper mold base 101 are connected to both sides of the slider 50 by a fixing block 103. The fixing block 103 is connected to the slider 50 by screws.
[0049] In summary, the key design feature of this utility model lies in its combination of a fine-tuning screw and a digital display. Rotating the fine-tuning screw causes the adjustment component to move up and down. The digital display records and displays the number of rotations of the fine-tuning screw, allowing for a direct visual representation of the fine-tuning dimension. This facilitates adjustment, reduces errors, and improves adjustment accuracy. Furthermore, the inclusion of a clamping plate, which locks or releases the fine-tuning screw, prevents secondary changes in its angle after adjustment, ensuring the adjusted gap remains unchanged. The digital display records and displays the number of rotations, allowing each increment to represent a specific adjustment distance, thus quantifying the fine-tuning dimension.
[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
