Description

Technical Field

[0001] The present invention relates to the field of battery wire binding equipment, and in particular to a battery steel shell wire binding depth fine-tuning mechanism. Background Art

[0002] During the battery production process, one end of the battery steel shell is usually "wire tied". Figure 1 As shown, a pair of upper and lower molds (101, 102) are used on a wire binding machine to clamp and position an upright battery steel shell 1000. Then, two wire binding wheels 103 located on both sides of the battery steel shell 1000, which hold the battery steel shell tightly and rotate at high speed with the axial direction of the battery steel shell 1000 as the rotation axis, bind the battery steel shell to form an annular groove on the outer wall of the battery steel shell. On the wire binding machine, the upper mold 101 and the two wire binding wheels 103 are both installed on the rotating shaft assembly 104 of the wire binding head, wherein the upper mold 101 is installed on the lower end of the rotating shaft assembly 104 through a bearing, and the two wire binding wheels 103 are located on both sides of the upper mold 101 and are swingably installed on the rotating shaft assembly 104. In order to make the two wire-binding wheels 103 swing to approach or move away from the battery steel shell 1000 clamped between the upper and lower molds (101, 102), and to achieve the purpose of holding the battery steel shell 1000 tightly or loosening the battery steel shell 1000, a slide rod 105 that can slide up and down relative to the shaft assembly 104 is installed axially through the shaft assembly 104, and the lower end of the slide rod 105 is a frustum structure with a diameter gradually narrowing from top to bottom. The lower end of the slide rod 105 is located between the upper ends of the swing arms of the two wire-binding wheels 103. The slide rod 105 The upper end is mounted on the bearing sleeve 106 through a bearing. The bearing sleeve 106 is laterally limited in the cam groove 1071 on the cam mechanism 107, whose horizontal height changes in an up and down curve. When the entire wire-binding head rotates along the cam groove 1071 of the cam mechanism 107, the bearing sleeve 106 and the slide bar 105 mounted thereon move up and down corresponding to the curve change of the cam groove 1071. The slide bar 105 that moves up and down controls the two wire-binding wheels 103 to approach or move away from the battery steel shell 1000, thereby realizing the binding of the battery steel shell.

[0003] In a wire binding machine, the installation height of the slide bar 105 directly affects and determines the depth of the wire binding of the battery steel shell. In order to achieve precise wire binding of the battery steel shell or wire binding of the battery steel shell according to different wire binding requirements, the installation height of the slide bar 105 often needs to be adjusted. Moreover, the accuracy of the installation position of the slide bar 105 can only be determined after the slide bar 105 is installed and the wire binding operation is performed. If it is not accurate, the slide bar 105 needs to be removed and the installation position of the slide bar 105 needs to be repeatedly readjusted. However, the existing slide bar 105 is directly installed on the bearing sleeve 106. When adjusting the installation height of the slide bar 105, the bearing sleeve 106 and the slide bar 105 need to be disassembled and then installed again, which is very inconvenient to operate and the adjustment accuracy cannot be guaranteed. Summary of the Invention

[0004] The purpose of the present invention is to provide a battery steel shell binding wire depth fine-tuning mechanism.

[0005] The technical solution for achieving the purpose of the present invention is: a battery steel shell wire binding depth fine-tuning mechanism, comprising a first adjusting sleeve, a second adjusting sleeve, an equally divided sleeve, and a sliding rod with a frustum structure at the lower end and located between the upper ends of the two wire binding wheel swing arms, the first adjusting sleeve having an internal thread, the first adjusting sleeve being sleeved on the sliding rod and being threadedly connected to the upper end of the sliding rod having an external thread, the first adjusting sleeve being installed in a bearing sleeve on a cam mechanism which is laterally limited through a bearing, the upper end of the first adjusting sleeve being higher than the bearing sleeve, the first adjusting sleeve being higher than the upper end of the bearing sleeve and extending radially outward to a limiting portion, the limiting portion of the first adjusting sleeve and the second adjusting sleeve being both hollow and having a regular polygonal cross-section, the first adjusting sleeve The limiting portion of an adjusting sleeve has the same number of sides and the same circumscribed circle radius as the second adjusting sleeve. The second adjusting sleeve is located above the first adjusting sleeve and is fixedly mounted on the sliding rod. The cross-section of the inner hole surface of the equally divided sleeve is a uniform and regular triangular waveform. The groove angle of the inner hole surface of the triangular waveform of the equally divided sleeve is equal to the inner angle of the regular polygon structure of the limiting portion of the first adjusting sleeve. The circumscribed circle radius of the inner hole surface of the triangular waveform of the equally divided sleeve is the same as the circumscribed circle radius of the regular polygon structure of the limiting portion of the first adjusting sleeve. The number of groove angles on the inner hole surface of the equally divided sleeve is a positive integer multiple of the number of sides of the regular polygon structure of the limiting portion of the first adjusting sleeve. The equally divided sleeve is simultaneously mounted on the limiting portion of the first adjusting sleeve and the outside of the second adjusting sleeve.

[0006] Furthermore, the number of sides of the limiting portion of the first adjustment sleeve is more than three. The cross section of the limiting portion of the first adjustment sleeve can be a hollow regular triangle, square, regular pentagon, regular hexagon or regular polygon with more sides.

[0007] Furthermore, the cross section of the limiting portion of the first adjustment sleeve is a hollow regular hexagon. The regular hexagonal structure is more conventional, easier to process, and more convenient to obtain materials.

[0008] Furthermore, the number of groove angles on the equally divided sleeve inner hole surface is 3 to 5 times the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion. The greater the number of groove angles on the equally divided sleeve inner hole surface relative to the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion, the higher the adjustment accuracy. However, considering actual processing, the number of groove angles on the equally divided sleeve inner hole surface is typically 3 to 5 times the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion.

[0009] Furthermore, the number of groove angles that equally divide the inner hole surface of the sleeve is four times the number of sides of the regular polygonal structure of the limiting portion of the first adjustment sleeve.

[0010] Furthermore, the number of groove angles equally dividing the inner hole surface of the sleeve is 24.

[0011] Furthermore, the dividing sleeve has a threaded through-hole, into which a locking screw is inserted, which laterally secures the first adjustment sleeve. After the dividing sleeve is positioned outside the first and second adjustment sleeves, the locking screw secures the first adjustment sleeve, preventing the dividing sleeve from being dislodged from the first adjustment sleeve's retaining portion due to vibration or accidental movement, thus ensuring structural stability. To adjust, simply loosen the locking screw and then lift the dividing sleeve. Once adjusted, tighten the locking screw.

[0012] Furthermore, the second adjusting sleeve is fixed to the slide rod by a set screw. This arrangement facilitates the disassembly and assembly of the second adjusting sleeve.

[0013] Furthermore, a washer mounted on the slide rod is installed between the first adjustment sleeve limit portion and the bearing sleeve. The washer isolates the dividing sleeve from the bearing and the bearing sleeve, thereby preventing the bearing and the bearing sleeve from being worn when the dividing sleeve is inserted into the first adjustment sleeve limit portion.

[0014] The battery steel shell binding wire depth fine-tuning mechanism of the present invention avoids direct installation of the slide rod and the bearing sleeve through the first adjusting sleeve installed on the slide rod external thread sleeve and the bearing sleeve through the bearing, and at the same time allows the slide rod to rotate relative to the first adjusting sleeve and the bearing sleeve and move up and down, so that during the adjustment process of the battery steel shell binding wire depth, there is no need to disassemble the bearing sleeve and the bearing, and it is only necessary to lift the equal-dividing sleeve connecting the slide rod and the limiting part of the first adjusting sleeve and rotate the slide rod, which greatly improves the convenience of adjustment; and, the present invention can achieve high-precision adjustment of the up and down movement position of the slide rod by increasing the number of groove angles on the inner hole surface of the equal-dividing sleeve. For example, when the number of groove angles on the inner hole surface of the equal-dividing sleeve is set to 24, the adjustment accuracy of the up and down movement position of the slide rod can be as high as 0.01mm.

[0024] The following is a detailed description of the specific embodiment of the battery steel shell binding wire depth fine-tuning mechanism of the present invention with reference to the accompanying drawings:

[0025] like Figures 2 to 8 As shown, a battery steel shell wire-binding depth fine-tuning mechanism comprises a first adjusting sleeve 1, a second adjusting sleeve 2, an equally divided sleeve 3, and a slide rod 10 with a frustum structure at the lower end and located between the upper ends of the swing arms of the two wire-binding wheels 20. The first adjusting sleeve 1 has an internal thread 11, the first adjusting sleeve 1 is sleeved on the slide rod 10 and is threadedly connected to the upper end of the slide rod 10 with an external thread. The first adjusting sleeve 1 is installed in a bearing sleeve 30 laterally limited on the cam mechanism 40 through a bearing 301. The upper end of the first adjusting sleeve 1 is higher than the bearing sleeve 30. The first adjusting sleeve 1 is higher than the upper end of the bearing sleeve 30 and extends radially outward to form a limiting portion 12. The limiting portion 12 of the first adjusting sleeve 1 and the second adjusting sleeve 2 are both hollow and have a regular polygonal cross-section. The first adjusting sleeve 1 and the second adjusting sleeve 2 have the same number of sides and the same circumscribed circle radius. The second adjusting sleeve 2 is located above the first adjusting sleeve 1 and is fixedly mounted on the slide rod 10. The cross-section of the inner hole surface 31 of the equally divided sleeve 3 is a uniform and regular triangular waveform. The groove angle α of the triangular waveform of the inner hole surface 31 of the equally divided sleeve 3 is equal to the inner angle β of the regular polygon structure of the limiting portion 12 of the first adjusting sleeve. The circumscribed circle radius of the triangular waveform of the inner hole surface 31 of the equally divided sleeve 3 is the same as the circumscribed circle radius of the regular polygon structure of the limiting portion 12 of the first adjusting sleeve. The number of groove angles of the inner hole surface 31 of the equally divided sleeve 3 is a positive integer multiple of the number of sides of the regular polygon structure of the limiting portion 12 of the first adjusting sleeve. The equally divided sleeve 3 is simultaneously mounted on the limiting portion 12 of the first adjusting sleeve 1 and the outside of the second adjusting sleeve 2.

[0026] The battery steel shell binding depth fine-tuning mechanism of the present invention adjusts the installation height of the slide bar 10 to adjust the binding depth of the battery steel shell by lifting the equal-dividing sleeve 3. Figure 9As shown, the equally divided sleeve 3 is no longer mounted on the limiting portion 12 of the first adjustment sleeve, but is still mounted on the second adjustment sleeve 2. Then, the slide rod 10 is rotated relative to the first adjustment sleeve 1 to move the slide rod 10 up or down. After adjustment, the equally divided sleeve 3 is lowered and mounted on the limiting portion 12 of the first adjustment sleeve.

[0027] The battery steel shell wire-binding depth fine-tuning mechanism of the present invention is as follows: when the slide bar 10 moves upward, the battery steel shell wire-binding depth becomes shallower; when the slide bar 10 moves downward, the battery steel shell wire-binding depth becomes deeper.

[0028] The battery steel shell binding wire depth fine-tuning mechanism of the present invention has a groove angle α of the circular inner hole surface 31 of the triangular waveform of the equally divided sleeve 3 and an inner angle β of the regular polygon structure of the first adjustment sleeve limiting portion 12, which ensures that the corner of the regular polygon structure of the first adjustment sleeve limiting portion 12 can be assembled into the groove angle of the circular inner hole surface 31 of the triangular waveform of the equally divided sleeve 3; the circumscribed circle radius of the triangular waveform of the inner hole surface 31 of the equally divided sleeve 3 is the same as the circumscribed circle radius of the regular polygon structure of the first adjustment sleeve limiting portion 12, which functions to ensure that the first adjustment sleeve limiting portion 12 can be exactly sleeved in the equally divided sleeve 3; the number of groove angles of the inner hole surface 31 of the equally divided sleeve 3 is a positive integer multiple of the number of sides of the regular polygon structure of the first adjustment sleeve limiting portion 12, which ensures that the first adjustment sleeve limiting portion 12 can not only be nested and clamped in the circular inner hole of the equally divided sleeve 3, but also that the equally divided sleeve 3 can be sleeved at several different angles relative to the first adjustment sleeve limiting portion 12 in the circumferential direction.

[0029] In the battery steel shell binding wire depth fine-tuning mechanism of the present invention, the limiting portion 12 of the first adjustment sleeve 1 and the second adjustment sleeve 2 are both hollow regular polygonal structures. The limiting portion 12 of the first adjustment sleeve 1 and the second adjustment sleeve 2 have the same number of sides and the same circumscribed circle radius, ensuring that the second adjustment sleeve 2 can be installed in the equally divided sleeve 3 in the same way as the limiting portion 12 of the first adjustment sleeve 1.

[0030] In the battery steel shell binding wire depth fine-tuning mechanism of the present invention, after the equally divided sleeve 3 is simultaneously sleeved outside the limiting portion 12 of the first adjustment sleeve 1 and the second adjustment sleeve 2, the limiting connection of the equally divided sleeve 3 ensures that the second adjustment sleeve 2 and the sliding rod 10 fixedly connected thereto and the first adjustment sleeve 1 will not produce relative rotation and axial movement.

[0031] In the battery steel shell binding wire depth fine-tuning mechanism of the present invention, the number of groove angles on the inner hole surface 31 of the equally divided sleeve 3 determines the adjustment accuracy. The more groove angles on the inner hole surface 31 of the equally divided sleeve 3, the higher the adjustment accuracy. When the equally divided sleeve 3 rotates one groove angle position relative to the limiting portion 12 of the first adjustment sleeve 1, the axial movement distance of the slide rod 10 is the adjustment accuracy of the present invention.

[0032] The battery steel shell binding depth fine-tuning mechanism of the present invention avoids direct installation of the slide rod 10 and the bearing sleeve 30 by the first adjusting sleeve 1 installed on the external thread sleeve of the slide rod 10 and the bearing sleeve 30 through the bearing 301, and at the same time enables the slide rod 10 to rotate relative to the first adjusting sleeve 1 and the bearing sleeve 30 and move up and down, so that during the adjustment process of the battery steel shell binding depth, there is no need to disassemble the bearing sleeve 30 and the bearing 301. It is only necessary to lift the equal-dividing sleeve 3 connecting the slide rod 10 and the first adjusting sleeve limiting portion 12 and rotate the slide rod 10, which greatly improves the convenience of adjustment; and, the present invention can achieve high-precision adjustment of the up and down movement position of the slide rod 10 by increasing the number of groove angles on the inner hole surface 31 of the equal-dividing sleeve 3. For example, when the number of groove angles on the inner hole surface 31 of the equal-dividing sleeve 3 is set to 24, the adjustment accuracy of the up and down movement position of the slide rod 10 can be as high as 0.01mm.

[0033] In the battery steel shell tie wire depth fine-tuning mechanism of the present invention, the number of sides of the limiting portion 12 of the first adjustment sleeve 1 is three or more. The cross-section of the limiting portion 12 of the first adjustment sleeve 1 can be a hollow equilateral triangle, square, regular pentagon, regular hexagon, or regular polygon with more sides.

[0034] In the battery steel shell tie wire depth fine-tuning mechanism of the present invention, preferably, the cross section of the limiting portion 12 of the first adjustment sleeve 1 is a hollow regular hexagon. The regular hexagonal structure is more conventional, easier to process, and more convenient to obtain materials.

[0035] In the battery steel shell tie wire depth fine-tuning mechanism of the present invention, preferably, the number of groove angles on the inner hole surface 31 of the equally divided sleeve 3 is 3 to 5 times the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion 12. The number of groove angles on the inner hole surface 31 of the equally divided sleeve 3 is a higher multiple of the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion 12. The greater the number of groove angles on the inner hole surface 31 of the equally divided sleeve 3, the higher the adjustment accuracy. However, considering actual processing, the number of groove angles on the inner hole surface 31 of the equally divided sleeve 3 is typically 3 to 5 times the number of sides of the regular polygonal structure of the first adjustment sleeve limiting portion 12.

[0036] In the battery steel shell binding wire depth fine-tuning mechanism of the present invention, preferably, the number of groove angles of the inner hole surface 31 of the equally divided sleeve 3 is 4 times the number of sides of the regular polygon structure of the first adjustment sleeve limiting portion 12.

[0037] The battery steel shell binding wire depth fine-tuning mechanism of the present invention has 24 groove corners that equally divide the inner hole surface 31 of the sleeve 3.

[0038] The present battery steel shell tie-line depth fine-adjustment mechanism preferably comprises a threaded through-hole 32 formed in the dividing sleeve 3, within which a locking screw 33 is inserted. This locking screw 33 laterally secures the first adjustment sleeve 1. After the dividing sleeve 3 is positioned over the first and second adjustment sleeves 1 and 2, the locking screw 33 secures the first adjustment sleeve 1. This prevents the dividing sleeve 3 from being dislodged from the retaining portion 12 of the first adjustment sleeve 1 due to vibration or accidental movement, thereby ensuring structural stability. To adjust, simply loosen the locking screw 33 and then lift the dividing sleeve 3. Once adjustment is complete, tighten the locking screw 33.

[0039] In the battery steel shell binding wire depth fine-tuning mechanism of the present invention, preferably, the second adjustment sleeve 2 is fixed to the slide bar 10 by a set screw 21. This arrangement facilitates the disassembly and assembly of the second adjustment sleeve 2.

[0040] In the battery steel shell tie wire depth fine-tuning mechanism of the present invention, preferably, a gasket 4 mounted on the slide rod 10 is installed between the first adjustment sleeve limiter 12 and the bearing sleeve 30. The gasket 4 isolates the dividing sleeve 3 from the bearing 301 and the bearing sleeve 30, thereby preventing the bearing 301 and the bearing sleeve 30 from being worn when the dividing sleeve 3 is inserted into the first adjustment sleeve limiter 12.

[0041] For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
