Description

Technical Field

[0001] This utility model relates to the field of installation auxiliary tools, and in particular to a spring seat sleeve steel ball installation device. Background Technology

[0002] In construction machinery, spring seat sleeves require the installation of multiple sets of steel balls, and each set may contain several steel balls. The surface of the steel balls needs to be coated with grease to prevent wear. The current method is to first apply grease to the steel balls, and then manually install the greased steel balls into the spring seat sleeves using tweezers. However, manually installing each ball one by one with tweezers is inefficient, time-consuming, and the grease can easily cause the steel balls to fall out or become misaligned. Furthermore, manual control is difficult, resulting in low installation efficiency. Utility Model Content

[0003] To address the shortcomings of existing methods that use grease to install steel balls, this invention provides a steel ball installation device for spring seat sleeves. This device has advantages such as simple structure, low manufacturing cost, simple steel ball installation method, and high installation efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A spring seat sleeve steel ball mounting device is provided, wherein the spring seat sleeve is provided with a steel ball groove for accommodating steel balls, including a ball guiding mechanism and a lower mold for mounting the spring seat sleeve. The ball guiding mechanism includes a sleeve and a pushing part. The sleeve is provided with a steel ball groove capable of holding at least one steel ball. One end of the steel ball groove is open. The pushing part is slidably connected to the sleeve. One end of the pushing part is located in the steel ball groove and can slide in the steel ball groove.

[0005] Using the above technical solution, steel balls coated with grease are loaded into the sleeve of the guide ball mechanism. The spring seat is installed on the lower mold of the seat. Because the steel balls are coated with grease, the grease adheres and makes it difficult for the steel balls to detach from the inside of the guide ball mechanism on their own. Therefore, a pushing part needs to be set inside the guide ball mechanism to push the steel balls to ensure that the steel balls can be smoothly detached and enter the slide. After installation, the spring seat and the lower mold of the seat are separated. The sleeve is provided with a steel ball groove that can hold at least one steel ball, so that the guide ball mechanism can load multiple steel balls at the same time. Correspondingly, it can also complete the simultaneous installation of a row of multiple steel balls, thus improving the installation efficiency.

[0006] Furthermore, the lower mold of the seat sleeve includes a base and a guide post. The guide post is installed on the upper end of the base, the base supports the spring seat sleeve, the spring seat sleeve is sleeved on the outside of the guide post, and the side wall of the guide post is provided with a through groove, which is spliced ​​with the steel ball groove to form a slide for installing steel balls.

[0007] Using the above technical solution, the base abuts against the bottom of the spring seat sleeve, facilitating the removal of the lower mold of the seat sleeve. The guide post is set at the top of the base and passes through the inner cavity of the spring seat sleeve. The side wall of the guide post is provided with a through groove, which is spliced ​​with the steel ball groove to form a slide for installing steel balls. This increases the installation area of ​​the steel balls, which can better position the steel balls and prevent them from slipping out of the inner cavity of the spring seat sleeve. Compared with the steel ball groove set separately in the inner cavity of the spring seat sleeve, the inner groove set in the guide post further restricts the rolling channel for steel ball installation, which can prevent steel balls from slipping out, making the installation efficiency higher and playing a positioning role for the spring seat sleeve when loading steel balls.

[0008] Furthermore, the cross-section of the ball groove is a superior arc, while the cross-section of the through groove is a inferior arc that matches the ball groove.

[0009] By adopting the above technical solution, the steel ball groove is set with an optimal arc so that the steel ball will not detach from the steel ball groove after the spring seat and the lower mold of the seat are separated, thus ensuring the stability of the steel ball installation.

[0010] Furthermore, the spring seat sleeve is provided with a mounting hole, and the base is provided with a positioning post that matches the mounting hole. The positioning post is sleeved with the mounting hole to achieve circumferential positioning of the spring seat sleeve and the base.

[0011] By adopting the above technical solution and setting positioning posts and mounting holes, the spring seat and the lower mold of the seat can be better spliced. When the positioning posts are inserted into the mounting holes, the ball groove and the through groove are perfectly spliced, making the splicing of the ball groove and the through groove more accurate and efficient.

[0012] Furthermore, the spring seat sleeve steel ball mounting device also includes a feeding upper mold, which is installed above the guide column. The feeding upper mold includes an upper cover and a sleeve part. The sleeve part is fixed to the bottom end of the upper cover. The spring seat sleeve is sleeved on the outside of the sleeve part. The upper cover covers the spring seat sleeve. The upper cover and the sleeve part have through steel ball mounting holes. After the feeding upper mold is installed, the axis of the steel ball mounting hole coincides with the axis of the slide.

[0013] Using the above technical solution, the ball outlet of the guide ball mechanism is aligned with the ball mounting hole, the sleeve is fitted onto the upper cavity of the spring seat, and the upper cover abuts against the top of the spring seat, securing a detachable connection between the upper feed die and the spring seat. The upper cover and the sleeve have through-holes for the ball mounting. The guide ball mechanism pushes the ball into the mounting hole, and the axis of the mounting hole coincides with the axis of the slide. The ball slides down from the mounting hole to the slide, thus completing the ball mounting. The coincidence of the axis of the mounting hole and the axis of the slide extends the slide to a certain extent, eliminating interference caused by the wall thickness of the guide ball mechanism. This allows the guide ball mechanism to be perfectly aligned with the slide for installation, ensuring installation accuracy.

[0014] Furthermore, the steel ball mounting hole is divided into a first steel ball mounting hole and a second steel ball mounting hole. The first steel ball mounting hole is the steel ball mounting hole opened on the top cover, and the second steel ball mounting hole is the steel ball mounting hole opened on the sleeve part. The cross-sectional area of ​​the first steel ball mounting hole is larger than that of the second steel ball mounting hole, and the end of the sleeve is adapted to the shape of the first steel ball mounting hole.

[0015] By adopting the above technical solution, when installing steel balls, the steel ball ejection end of the guide ball mechanism is directly installed in the first steel ball mounting hole, and the steel ball is ejected. The steel ball is then installed in the slide through the first steel ball mounting hole and the second steel ball mounting hole in sequence. The installation is carried out by aligning the steel ball holes with the holes, which ensures that the steel ball will not roll around randomly and improves the accuracy and efficiency of steel ball installation.

[0016] Furthermore, the guide post is provided with a first positioning part, and the upper feeding die is provided with a second positioning part. The first positioning part and the second positioning part cooperate to achieve circumferential positioning of the upper feeding die and the guide post. The upper feeding die is provided with a steel ball mounting hole, and the steel ball mounting hole is aligned with the corresponding slide.

[0017] Using the above technical solution, the first positioning part is opened on the guide post of the lower mold of the seat sleeve, and the second positioning part is opened on the upper mold of the feeding. The first positioning part and the second positioning part cooperate to complete the circumferential positioning of the upper mold of the feeding and the guide post, ensuring the accurate positioning of the steel ball mounting hole and the slide of the upper mold of the feeding, and to a certain extent, it plays a connecting role between the upper mold of the feeding and the lower mold of the seat sleeve, so that the two will not easily loosen.

[0018] Furthermore, the sleeve includes a first plate and several second plates, one end of which is connected to the first plate, and there is a long notch between the several second plates.

[0019] Using the above technical solution, one side of the second plate is connected to the first plate, and the other side of the second plate is open. The sleeve is a hollow cavity composed of several second plates. The steel ball is installed in the hollow cavity. In order to conform to the spherical shape of the steel ball, the second plates are connected to the first plate in a circular circumference, and the radius of the second plate is the same as the radius of the circumference circle. There are long gaps between adjacent second plates, which can accommodate steel balls of various sizes.

[0020] Furthermore, the length of the pushing part is greater than the length of the sleeve, so that all the steel balls are pushed out of the sleeve.

[0021] If the above technical solution is adopted, and the steel ball is pushed in the sleeve by the pushing part, its length cannot completely push all the steel ball out of the sleeve. In this case, the steel ball may stick to the lower half of the sleeve that the pushing part cannot reach. The pushing part is longer than the sleeve, which ensures that the steel ball can be completely pushed out of the sleeve.

[0022] The beneficial effects of this utility model are: (1) simple structure and low manufacturing cost; (2) simple disassembly and assembly method of clamping mechanism and high disassembly and assembly efficiency; (4) can adapt to the installation of steel balls of different sizes.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a positioning steel ball 20 mounting device for a spring seat 10. The spring seat 10 is provided with a steel ball groove 51 for accommodating the steel ball 20. Figures 1 to 3 As shown, it includes a guide ball mechanism 40 and a lower mold 31 for mounting the spring seat 10. The guide ball mechanism 40 includes a sleeve 42 and a pushing part 41. The sleeve 42 is provided with a steel ball 20 mounting groove that can hold at least one steel ball 20. One end of the steel ball 20 mounting groove is open. The pushing part 41 is slidably connected to the sleeve 42. One end of the pushing part 41 is located in the steel ball 20 mounting groove and can slide in the steel ball 20 mounting groove.

[0027] Among them, the sleeve 42 is a cylindrical hollow cylinder structure used to load the steel ball 20; it should be noted that the sleeve 42 is not limited to a cylindrical hollow cylinder, but can also be a cuboid hollow cylinder or other polygonal hollow cylinders. It is preferred to use a cylinder, which is more compatible with the shape of the steel ball 20.

[0028] In practice, steel balls 20 coated with grease are loaded into the ball groove 51 of the sleeve 42. The sleeve 42 has a through hole for the pusher 41 to pass through. The pusher 41 is slidably connected to the sleeve 42, and can be pushed forward to push the steel balls 20 out of the sleeve 42. The lower mold 31 of the seat sleeve is sleeved with the spring seat sleeve 10 to support the spring seat sleeve 10 and keep it stable. During operation, a wire retaining ring 12 and a baffle 13 are first installed at the bottom of the spring seat sleeve 10 to prevent the installed steel balls 20 from falling out of the spring seat sleeve 10. Then, the lower mold 31 of the seat sleeve is sleeved and installed at the bottom of the spring seat sleeve 10. Then, the pusher 41 of the ball guide mechanism 40 pushes the steel balls 20, so that the steel balls 20 overcome the sticking effect of the grease and fall out one by one into the slide 50. After the steel balls 20 are installed, the lower mold 31 of the seat sleeve and the spring seat sleeve 10 are separated.

[0029] The size of the ball bearing 20 loading slot is adapted to the ball bearing 20, that is, the size of the ball bearing 20 loading slot is slightly larger than the ball bearing 20, so that it can be used to load the ball bearing 20. The ball bearing 20 can slide in the ball bearing 20 loading slot. Due to the presence of grease, and the grease has a certain stickiness, the ball bearing 20 is stuck in the ball bearing 20 loading slot by the grease. When the push rod 411 does not push the ball bearing 20, the ball bearing 20 will not move in the ball bearing 20 loading slot. Thus, when installing the ball bearing 20, without pushing the push rod 411, the ball bearing 20 will not fall out of the opening of the ball bearing 20 loading slot. When the opening of the ball bearing 20 loading slot is aligned with the ball bearing groove 51 of the spring seat 10, pushing the push rod 411 can make the ball bearing 20 enter the ball bearing groove 51 of the spring seat 10 from the ball bearing 20 loading slot.

[0030] In another embodiment, a long notch 423 is provided on one side of the steel ball 20 loading slot. The size of the steel ball 20 loading slot is slightly smaller than that of the steel ball 20. The steel ball 20 fits tightly with the steel ball 20 loading slot. Due to the presence of the long notch 423, the sleeve 42 can elastically deform to clamp the steel ball 20. When installing the steel ball 20, without pushing the push rod 411, the steel ball 20 will not fall out of the opening of the steel ball 20 loading slot. When the opening of the steel ball 20 loading slot is aligned with the steel ball groove 51 of the spring seat 10, the push rod 411 is pushed. The pushing force of the push rod 411 can make the steel ball 20 overcome the friction between the steel ball 20 and the inner wall of the steel ball 20 loading slot, so that the steel ball 20 enters the steel ball groove 51 of the spring seat 10 from the steel ball 20 loading slot.

[0031] In one embodiment, the lower mold 31 of the seat cover includes a base 311 and a guide post 312. The guide post 312 is installed on the upper end of the base 311. The base 311 supports the spring seat cover 10. The spring seat cover 10 is sleeved on the outside of the guide post 312. The side wall of the guide post 312 is provided with a through groove 52. The through groove 52 is spliced ​​with the steel ball groove 51 to form a slide 50 for installing steel balls 20.

[0032] Among them, the ball groove 51 is a ball 20 mounting groove set in the inner cavity 11 of the spring seat sleeve 10, and the through groove 52 is a groove-shaped body set on the side wall of the guide post 312 that is symmetrical with the ball groove 51 and has the same shape. Preferably, the ball groove 51 and the through groove 52 are both semi-circular in shape, and the two are spliced ​​to form a slide 50 with a circular cross section. The slide 50 with a circular cross section is more in line with the shape of the ball 20, so that the ball 20 falls without obstruction, and after the clamping mechanism 30 is removed, the shape of the ball groove 51 can better fix the ball 20.

[0033] The slide 50 is a groove 52 on the guide post 312 of the lower mold 31 of the seat sleeve and a ball groove 51 in the inner cavity 11 of the spring seat sleeve 10, which accommodates the steel balls 20. After the steel balls 20 are installed, the lower mold 31 of the seat sleeve is disassembled, leaving only the ball groove 51 in the inner cavity 11 of the spring seat sleeve 10. The specific number of slides 50 is determined by the number of steel ball 20 installation groups required for the spring seat sleeve 10. The ball guide mechanism 40 can hold more than one steel ball 20, and the steel balls 20 inside the ball guide mechanism 40 can be loaded according to the number of steel balls 20 required for one slide 50.

[0034] In specific implementation, the base 311 abuts against the bottom of the spring seat 10, facilitating the removal of the lower mold 31 of the seat. The guide post 312 is set at the top of the base 311 and passes through the inner cavity 11 of the spring seat 10. The side wall of the guide post 312 is provided with a through groove 52. The through groove 52 and the ball groove 51 are spliced ​​together to form a slide 50 for installing the ball 20, which increases the installation area of ​​the ball 20 and can better position the ball 20, preventing it from slipping out of the inner cavity 11 of the spring seat 10. Compared with the separately set ball groove 51 in the inner cavity 11 of the spring seat 10, the inner groove of the guide post 312 further restricts the rolling channel for installing the ball 20, which can prevent the ball 20 from slipping out, making the installation more efficient and playing a positioning role for the spring seat 10 when loading the ball 20.

[0035] In one embodiment, the cross-section of the steel ball 20 mounting groove is a superior arc, and the cross-section of the through groove 52 is a inferior arc that matches the steel ball 20 mounting groove.

[0036] In specific implementation, such as Figure 4As shown, the horizontal cross-section of the ball groove 51 is a superior arc with an arc length of w1, and the horizontal cross-section of the through groove 52 is a minor arc that completes the ball groove 51 with an arc length of w2. That is, w1 is longer than w2. The ball 20 itself is covered with grease, and the balls 20 are stuck together. This prevents the balls 20 from easily slipping out of the ball groove 51 of the spring seat 10 after the lower mold 31 of the seat is removed due to the large limiting effect of the ball groove 51 and the sticking effect of the grease.

[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, the spring seat 10 is provided with a mounting hole 62, and the base 311 is provided with a positioning post 61 that is adapted to the mounting hole 62. The positioning post 61 is sleeved with the mounting hole 62 to realize the circumferential positioning of the spring seat 10 and the base 311.

[0038] In practice, by setting positioning pins 61 and mounting holes 62, the spring seat 10 and the lower mold 31 of the seat can be better spliced. When the positioning pins 61 are inserted into the mounting holes 62, the ball groove 51 and the through groove 52 are spliced ​​together, making the splicing of the ball groove 51 and the through groove 52 more accurate and efficient.

[0039] In one embodiment, the spring seat 10 steel ball 20 mounting device further includes a feeding upper mold 32, which is mounted above the guide post 312. The feeding upper mold 32 includes an upper cover 321 and a sleeve portion 322. The sleeve portion 322 is fixed to the bottom end of the upper cover 321. The spring seat 10 is sleeved on the outside of the sleeve portion 322. The upper cover 321 covers the spring seat 10. The upper cover 321 and the sleeve portion 322 have through steel ball 20 mounting holes 62. After the feeding upper mold 32 is installed, the axis of the steel ball 20 mounting hole 62 coincides with the axis of the slide 50.

[0040] In practical implementation, the steel ball 20 mounting device for the spring seat sleeve 10 includes not only the lower mold 31 but also a separate upper feeding mold 32. The lower mold 31 is installed at the bottom of the spring seat sleeve 10, and the upper feeding mold 32 is installed at the top of the spring seat sleeve 10. During installation, the lower mold 31 is installed first, followed by the upper feeding mold 32. Both are detachably fitted onto the spring seat sleeve 10 from the top and bottom, respectively, facilitating easy assembly and disassembly during operation. After installation, the upper feeding mold 32 is disassembled, and a wire retaining ring 12 and a baffle 13 are used to secure the upper mounting hole of the spring seat sleeve 10. Then, the lower mold 31 and the spring seat sleeve are separated. The steel balls 20 inside the spring seat sleeve 10 are limited vertically by the wire retaining ring 12 and the baffle 13 to prevent them from detaching from the upper and lower sides of the spring seat sleeve 10.

[0041] In actual installation, if the upper feeding mold 32 is not used and the guide ball mechanism 40 is directly aligned with the slide rail 50, the wall thickness of the guide ball mechanism 40 interferes with the interior of the spring seat sleeve 10, making it impossible for the guide ball mechanism 40 to be directly aligned with the slide rail 50. It must be tilted at a certain angle to align with the slide rail 50 and push out the steel ball 20 for installation. Therefore, this application uses the upper feeding mold 32, which is provided with a through steel ball mounting hole 323. The axis of the steel ball mounting hole 323 coincides with the axis of the slide rail 50, extending the slide rail 50 to a certain extent through the steel ball mounting hole 323, eliminating the interference of the guide ball mechanism 40, and allowing the guide ball mechanism 40 to be completely aligned with the slide rail 50 for installation, thus ensuring the accuracy of installation.

[0042] In practice, the outlet of the ball 20 of the guide ball mechanism 40 is aligned with the ball mounting hole 323, the sleeve part 322 is sleeved on the upper part of the inner cavity 11 of the spring seat 10, and the upper cover 321 abuts against the top of the spring seat 10, so that the feeding upper mold 32 and the spring seat 10 are securely and detachably connected. The upper cover 321 and the sleeve part 322 are provided with through ball mounting holes 323. The guide ball mechanism 40 pushes the ball 20 into the ball mounting hole 323. The axis of the ball mounting hole 323 coincides with the axis of the slide 50. The ball 20 slides down from the ball mounting hole 323 to the slide 50, thereby completing the installation of the ball 20.

[0043] Preferably, the cross-sectional shape of the steel ball mounting hole 323 is circular, such as... Figure 6 As shown, the steel ball mounting hole 323 is divided into a first steel ball mounting hole 3231 and a second steel ball mounting hole 3232. The first steel ball mounting hole 3231 is the steel ball mounting hole 323 opened in the upper cover 321, and the second steel ball mounting hole 3232 is the steel ball mounting hole 323 opened in the sleeve part 322. The cross-sectional area of ​​the first steel ball mounting hole 3231 is larger than the cross-sectional area of ​​the second steel ball mounting hole 3232. The cross-section of the first steel ball mounting hole 3231 can accommodate the end face of the steel ball 20 pushed out by the guide ball mechanism 40.

[0044] In practice, when installing the steel ball 20, the steel ball 20 ejection end of the guide ball mechanism 40 is directly installed in the first steel ball mounting hole 3231, pushing out the steel ball 20. The steel ball 20 is then installed in the slide rail 50 through the first steel ball mounting hole 3231 and the second steel ball mounting hole 3232 in sequence. The steel ball 20 is installed by aligning the holes, which ensures that the steel ball 20 will not roll around randomly, thus improving the accuracy and efficiency of the steel ball 20 installation.

[0045] Preferably, the cross-sectional area of ​​the second steel ball mounting hole 3232 is equal to the cross-sectional area of ​​the slide rail 50. Specifically, the cross-sectional area of ​​the second steel ball mounting hole 3232 is the same as that of the slide rail 50. Preferably, both are circular in cross-section. If both have the same cross-sectional area, then both have the same radius and the same hole shape. The shape of the second steel ball mounting hole 3232 and the hole of the slide rail 50 are the same. After the steel ball 20 enters the second steel ball mounting hole 3232 from the first steel ball mounting hole 3231, the process is complete. This ensures that the steel ball 20 can smoothly slide into the slide rail 50 without contaminating the inner cavity 11 of the spring other than the slide rail 50.

[0046] In one embodiment, the end of the sleeve 42 is installed in the ball bearing mounting hole 323, and the shape of the end of the sleeve 42 is adapted to the shape of the ball bearing mounting hole 323.

[0047] In specific implementation, such as Figure 3 As shown, the end of the sleeve 42 is installed in the first steel ball mounting hole 3231, facing the bottom of the lower mold 31 of the seat sleeve. The first steel ball mounting hole 3231 is a tapered hole with a gradually decreasing diameter and an inverted isosceles trapezoid in vertical cross section. The shape of the end of the sleeve 42 near the steel ball mounting hole 323 matches the shape of the first steel ball mounting hole 3231. This design can more accurately align the guide ball mechanism 40 with the steel ball mounting hole 323, thereby accurately installing the steel ball 20 in the slide 50, so that the steel ball 20 will not detach from the guide ball mechanism 40 and the clamping mechanism 30 itself during the installation process.

[0048] Preferably, the design of the upper feed mold 32 extends the slide 50, so that the side wall of the guide ball mechanism 40 will not interfere and can be vertically aligned with the slide 50. The end of the sleeve 42 is inserted into the first steel ball mounting hole 3231, and the shape of the end of the sleeve 42 is adapted to the shape of the first steel ball mounting hole 3231, so as to avoid the steel ball 20 slipping off the installation trajectory due to the gap during the pushing process.

[0049] In one embodiment, such as Figure 5 and Figure 7 As shown, the guide post 312 is provided with a first positioning part 71, and the upper feeding die 32 is provided with a second positioning part 72. The first positioning part 71 and the second positioning part 72 cooperate to realize the circumferential positioning of the upper feeding die 32 and the guide post 312.

[0050] Specifically, the first positioning part 71 is opened on the guide post 312 of the lower mold 31 of the seat sleeve, specifically at the top center of the guide post 312. The second positioning part 72 is opened on the bottom of the upper mold 32 of the feeding part, specifically at the bottom center of the sleeve part 322. The second positioning part 72 is a protrusion, and the first positioning part 71 is a hole corresponding to the protrusion shape of the second positioning part 72. This design can ensure that the upper mold 32 of the feeding part and the lower mold 31 of the seat sleeve are accurately positioned, and to a certain extent, it plays a connecting role between the upper mold 32 of the feeding part and the lower mold 31 of the seat sleeve, so that the two will not easily loosen.

[0051] Furthermore, the first positioning part 71 is disposed on the top surface of the guide post 312. If the first positioning part 71 is set as a protrusion, it is easy to cause interference. Therefore, the protrusion can be set as the second positioning part 72, and the first positioning part 71 can be set as the hole corresponding to the protrusion, which can reduce interference.

[0052] In one embodiment, the sleeve 42 includes a first plate 421 and a plurality of second plates 422, one end of the plurality of second plates 422 being connected to the first plate 421, and a long notch 423 being present between the plurality of second plates 422.

[0053] In specific implementation, the first plate 421 is located on the side of the sleeve 42 away from the steel ball 20. One side of the second plate 422 is connected to the first plate 421, and the other end of the second plate 422 is installed in the first steel ball mounting hole 3231, matching the shape of the first steel ball mounting hole 3231. The sleeve 42 is a hollow cavity composed of several second plates 422, and the steel ball 20 is installed in the hollow cavity. The pushing part 41 passes through the first plate 421 and pushes the steel ball 20 inside the sleeve 42. Preferably, in order to conform to the spherical shape of the steel ball 20, the second plates 422 are circumferentially connected to the first plate 421, and the radius of the second plate 422 is the same as the radius of the circumferential circle. There is a long notch 423 between adjacent second plates 422, which can accommodate steel balls 20 of various sizes.

[0054] In one embodiment, the pushing part 41 includes a push rod 411 and a push plate 412. The push plate 412 is connected to one end of the push rod 411. The push rod 411 passes through a through hole, and the push plate 412 is installed inside the sleeve 42.

[0055] Preferably, a hand-held block can also be provided on the side of the push rod 411 away from the push plate 412 to facilitate hand-held pushing of the push rod 411.

[0056] In practice, the pusher 411 pushes the pusher plate 412, which pushes the steel ball 20 coated with grease forward in the sleeve 42. The pusher plate 412 is preferably a circular pusher plate with a radius slightly smaller than that of the sleeve 42, so that the contact area with the steel ball 20 is larger and it is easier to push the steel ball 20 out of the sleeve 42 step by step. In addition, the structure of the pusher 411 and the pusher plate 412 is simple and the manufacturing cost is low.

[0057] In one embodiment, the length of the pushing part 41 is greater than the length of the sleeve 42, so as to push all the steel balls 20 out of the sleeve 42.

[0058] In practice, if the steel ball 20 is pushed into the sleeve 42 by the pushing part 41, its length is not enough to push all the steel balls 20 out of the sleeve 42. In this case, the steel ball 20 may stick to the lower half of the sleeve 42 that the pushing part 41 cannot reach. The pushing part 41 is longer than the sleeve 42, specifically the length of the push rod 411 is longer than the length of the sleeve 42, which ensures that the steel ball 20 can be completely pushed out of the sleeve 42.

[0059] Furthermore, the adhesion of grease may also cause the steel ball 20 to stick in the steel ball 20 mounting hole 62 or the slide 50, making it impossible to install it in its corresponding position. Therefore, the pushing part 41 can be set to a sufficient length so that it can directly install the steel ball 20 into place, that is, the bottom steel ball 20 is directly positioned at the bottom of the steel ball groove 51, which can ensure that the steel ball 20 will not be improperly installed due to adhesion throughout the process.
