Description

Technical Field

[0001] This utility model relates to the field of slider installation technology for linear guide pairs, and in particular to an auxiliary device for roller slider installation. Background Technology

[0002] A rolling linear guide pair has a certain number of rolling elements, such as needle rollers, between the slider and the guide rail. The slider moves along the guide rail with low friction and long service life by rolling the rolling elements. In order to achieve arbitrary distance movement of the slider, a return device is generally set at the end of the slider. An inner rotating frame is set between the return device and the slider, so that the rolling elements can rotate infinitely between the ball return channel and the bearing area.

[0003] In general, when assembling the rolling elements in the slider of a rolling linear guide pair, such as Figure 1 As shown, first install the AB tube, then arrange the needle rollers at one end and push them into the raceway. Next, stand the slider upright and add needle rollers to the arc-shaped part at the head. Finally, put on the reverser end cap and repeat the same steps to install the other end. During the process of adding needle rollers, they are prone to falling off, and can only be added one at a time, resulting in low efficiency.

[0004] Therefore, an auxiliary device is needed to push the needle rollers into the raceway in one go after the reverser is installed, which can eliminate the need for additional needle rollers and improve efficiency. Utility Model Content

[0005] To address the aforementioned technical deficiencies, this invention provides a roller slider installation auxiliary device that enables the roller needle to be pushed into the raceway in one go, thereby improving assembly efficiency.

[0006] This utility model discloses a roller slider installation auxiliary device, including an auxiliary body. A groove is provided on one side of the auxiliary body, the two side walls of the groove are inclined, and the groove matches and fits the inner side of the slider. A feeding channel is provided inside the auxiliary body on both sides of the groove. The feeding channel extends inward from one end of the auxiliary body. A discharge port is provided in the middle of the auxiliary body. A pressure block is raised on the groove side wall of the auxiliary body on the side of the discharge port. The end of the pressure block corresponds to the locking hole on the AB tube of the slider. An inclined bevel is provided at the end of the pressure block corresponding to the locking hole. The bevel is used to abut against the locking hole. The bevel is inclined downward and faces outward. The discharge port is connected to the raceway of the slider. A telescopic mechanism is provided on the auxiliary body on the other side of the groove.

[0007] To simplify the device structure and make it easier to use, the telescopic mechanism is structured as follows: an installation cavity is provided in the auxiliary body on the other side of the groove, at least two guide posts are provided in the installation cavity, a pressure plate is sleeved on the guide posts, at least two support feet are spaced apart on the pressure plate, the support feet extend to the outside of the installation cavity, and a compression spring is sleeved on the guide posts, one end of the compression spring abuts against the pressure plate, and the other end abuts against the side wall of the installation cavity near the groove.

[0008] To facilitate manual compression of the compression spring, a first handle is provided on the side of the auxiliary body near the groove end, and a second handle is provided on the pressure plate. An elongated hole is provided on the auxiliary body at the second handle. The second handle extends to the outside of the auxiliary body and is located on the same side as the first handle. The length direction of the elongated hole is consistent with the axial direction of the guide post.

[0009] To ensure more stable movement and support of the support feet, the number of support feet is the same as the number of guide posts, the positions of the guide posts correspond to the positions of the support feet, the support feet have hollow guide holes inside, and the ends of the guide posts extend into the guide holes after passing through the pressure plate.

[0010] The roller slider installation auxiliary device obtained by this utility model provides roller needles directly into the slider through the feeding channel on the auxiliary body. The pressure block opens the locking hole so that the roller needles can smoothly enter the raceway, which can realize one-time assembly and improve assembly efficiency. Attached Figure Description

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1:

[0021] like Figures 2-8 As shown, this utility model discloses a roller slider installation auxiliary device, including an auxiliary body 3. A groove 16 is provided on one side of the auxiliary body 3. The two side walls of the groove 16 are inclined and the groove 16 matches and fits the inner side of the slider 1. A feeding channel 5 is provided inside the auxiliary body 3 on both sides of the groove 16. The feeding channel 5 extends inward from one end of the auxiliary body 3. A discharge port 17 is provided in the middle part of the auxiliary body 3. A pressure block 12 is protruding on the side wall of the groove 16 of the auxiliary body 3 on the side of the discharge port 17. The end of the pressure block 12 corresponds to the locking port 15 on the AB tube 14 of the slider 1. An inclined bevel 13 is provided at the end of the pressure block 12 corresponding to the locking port 15. The bevel 13 is used to abut against the locking port 15. The bevel 13 is inclined downward and faces outward. The discharge port 17 is connected to the raceway of the slider 1. A telescopic mechanism is provided on the auxiliary body 3 on the other side relative to the groove 16.

[0022] Since a groove 16 is provided on one side of the auxiliary body 3, and the groove 16 matches and fits the inner side of the slider 1, in actual use, the auxiliary body 3 can be placed inside the slider 1 with the groove 16 facing the slider 1. At this time, the discharge port 17 on the auxiliary body 3 on both sides of the groove 16 corresponds to the two raceways on one side of the slider 1. At the same time, the inclined opening 13 of the pressure block 12 at the discharge port 17 corresponds to the locking opening 15 and abuts against the locking opening 15. When the telescopic mechanism presses the auxiliary body 3 into the inside of the slider 1, the inclined opening 13 on the pressure block 12 opens the locking opening 15 on the AB tube 14 of the slider 1. Since the AB tube 14 is a plastic part, after the inclined opening 13 of the pressure block 12 abuts against the locking opening 15 of the AB tube 14, external force can be applied to open the corresponding locking opening 15 of the pressure block 12, so that the discharge port 17 is fully connected with the raceway. The roller needle can be pushed inward from one end of the feeding channel 5 and finally enter the raceway from the discharge port 17 until the raceway is full of rollers. Then, the telescopic mechanism retracts, releasing the external force applied to the auxiliary body 3, causing the locking jaw 15 to return to its original position and locking the roller inside the raceway, thus completing the assembly of the slider 1. Of course, before assembling the roller, the reverser 2 needs to be assembled at both ends of the slider 1. By using the auxiliary body 3 to assemble the needle rollers on the slider 1, the assembly of the needle rollers in two raceways can be completed in one clamping operation. Therefore, each slider 1 requires two clamping operations on the auxiliary body 3 to complete the assembly of the needle rollers in all four raceways.

[0023] The telescopic mechanism has the following structure: An installation cavity 6 is provided within the auxiliary body 3 on the opposite side of the groove 16. At least two guide posts 7 are provided within the installation cavity 6. A pressure plate 8 is fitted onto the guide posts 7. At least two support feet 4 are spaced apart on the pressure plate 8, extending to the outside of the installation cavity 6. A compression spring 9 is fitted onto the guide posts 7, with one end of the spring 9 abutting against the pressure plate 8 and the other end abutting against the side wall of the installation cavity 6 near the groove 16. The telescopic mechanism uses the guide posts 7, pressure plate 8, and compression spring 9 to provide pressure to the auxiliary body 3, making the overall structure more compact and suitable for various application scenarios. In actual use, the compression spring 9 is first compressed, causing the support feet 4 to partially retract into the installation cavity 6. The auxiliary body 3 can then be placed into the slider 1. The compression spring 9 is then released, and under its action, the support feet 4 are pushed outwards, thus pressing the auxiliary body 3 tightly against the inside of the slider 1. The pressure plate 8 then opens the locking jaw 15, achieving a stable connection between the auxiliary body 3 and the slider 1. In other embodiments, the telescopic mechanism may take the form of a cylinder, which is relatively large and requires an air pump to provide a high-pressure air source, thus limiting its use in certain environments.

[0024] A first handle 10 is provided on the side of the auxiliary body 3 near one end of the groove 16, and a second handle 11 is provided on the pressure plate 8. An elongated hole is provided on the auxiliary body 3 at the location of the second handle 11. The second handle 11 extends to the outside of the auxiliary body 3 and is located on the same side as the first handle 10. The length direction of the elongated hole is consistent with the axial direction of the guide post 7. The second handle 11 can be provided on the pressure plate 8 in the middle of the two support posts. By applying pressure between the first handle 10 and the second handle 11, the pressure spring 9 is overcome to retract the pressure plate 8 and the support leg inward, while the force is stable, which facilitates operation.

[0025] To make the movement and support of the support feet 4 more stable, the number of support feet 4 is the same as the number of guide posts 7, the position of the guide posts 7 corresponds to the position of the support feet 4, the support feet 4 have hollow guide holes inside, and the end of the guide post 7 extends into the guide hole after passing through the pressure plate 8.

[0026] The support foot 4 is connected to the guide post 7 through the guide hole, so that the support foot 4 slides stably and provides stable and reliable support for the auxiliary body 3.
