Description

Technical Field

[0001] The present application relates to the technical field of mechanical assembly, and in particular to an assembly fixture for a roller slider. Background Art

[0002] Roller linear guides utilize the rolling of rollers between the slide rail and the slider to cause relative movement between the two to achieve linear movement of the slider along the slide rail. In the roller linear guide assembly, a retaining frame for mounting rollers is provided between the slider and the slide rail. The retaining frame is provided with multiple channels for accommodating rollers. The ends of the retaining frame are arranged in an arc shape to facilitate the circulation and rolling of the rollers between the slider and the slide rail.

[0003] With the development of industrialization, roller installation is generally carried out by mechanized operations. The productivity of industrial production is mainly determined by highly automated mechanized assembly lines. However, even the most rigorous assembly lines require regular maintenance. In case of emergencies, during the period of temporary stagnation of mechanization, assembly production cannot be stopped. At this time, manual installation of rollers is required.

[0004] During manual assisted assembly production, roller installation is often inconvenient, and there are inevitable problems such as accuracy, efficiency, and uniformity. Even the tools that can be used are mostly simple in design and have limited auxiliary functions. Utility Model Content

[0005] The utility model aims to solve the technical problem that the existing roller linear guide rail has inconvenient operation of auxiliary assembly of rollers and low assembly precision.

[0006] To this end, the utility model provides a roller slider assembly fixture.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A roller slider assembly fixture, comprising:

[0009] A tray, wherein the tray is provided with a plurality of guide post grooves and a slide groove simultaneously connected to the ends of the plurality of guide post grooves;

[0010] A feeding tube, wherein the inner passage of the feeding tube is opposite to the slide groove, and an inserting portion is provided at one end of the feeding tube away from the tray, and the inserting portion is inserted into the channel on the retaining frame;

[0011] Among them, the end of the slide groove passes through the side wall of the pallet, and multiple rollers are arranged in the radial direction of the rollers themselves and are located in the slide groove. The length direction of the slide groove is consistent with the radial direction of the rollers. Multiple rollers are arranged in the axial direction of the rollers themselves and are located in the guide column groove. The length direction of the guide column groove is consistent with the axial direction of the rollers. The number of guide column grooves is a multiple of the number of rollers required for one channel on the retaining frame.

[0012] By adopting the above technical solution, after the rollers are arranged in the guide column groove, multiple rollers fall into the slide groove at the same time, so that multiple rollers are arranged in the slide groove. After the feeding tube is aligned with the slide groove, a row of rollers in the slide groove is pushed into the feeding tube. Through the plug-in cooperation between the plug-in part and the retaining frame, the feeding tube and the groove of the retaining frame are accurately connected, so that the rollers fall into the groove, thereby facilitating the installation of the rollers and improving the accuracy of the installation.

[0013] Furthermore, the length direction of the guide column groove is perpendicular to the length direction of the slide groove.

[0014] Furthermore, the cross section of the guide post groove in the xz plane is set to be U-shaped, and the width of the guide post groove cross section is adapted to the diameter of the roller.

[0015] Furthermore, the length of the slide groove in the y-axis direction is adapted to the axial length of the roller.

[0016] Furthermore, it also includes a loading fixture, which is plug-fitted with the tray, and the loading fixture is provided with a receiving groove for receiving the loading tube.

[0017] Furthermore, an abutment surface for abutting against an arc-shaped surface of a retaining frame is provided at one end of the feeding tube away from the tray, and the abutment surface is arranged in an arc shape.

[0018] Furthermore, the arc radius of the abutting surface is Ry, the arc radius of the end of the retaining frame is R, and Ry is greater than R.

[0019] By adopting the above technical solution, since the arc radius of the abutting surface of the feeding tube is relatively large, a margin can be left between its two ends and the retaining frame, ensuring that there is only one point in contact with the retaining frame and there will be no over-positioning.

[0020] Furthermore, the tangent point between the abutting surface and the arc surface of the retaining frame end is point P, and the distance between point P and the outer side wall of the feeding tube is A, and the size range of A is 3.3 to 3.5 mm.

[0021] Furthermore, the distance between the point P and the end face of the feeding tube is B, and the size range of B is 4.1 to 4.3 mm.

[0022] Furthermore, the end of the feeding tube provided with the abutment surface is connected with an inserting portion, and the distance between the inserting portion and the two walls in the retaining frame is 0.5-1.5 mm.

[0023] Furthermore, one end of the plug-in portion away from the tray is also configured to be arc-shaped, and the radius of the arc surface is Rx, and Ry is greater than Rx.

[0024] Furthermore, the top surface and the bottom surface of the tray are both provided with guide column grooves and sliding grooves.

[0025] The beneficial effect of the utility model is that the fixture has a simple structure and is made of light and cheap materials, but it can well improve the assembly efficiency and ensure the orderly production. By setting a guide column groove on the side wall of the tray that matches the number of rollers required for a single channel of the slider, the rollers can be loaded in an orderly and accurate manner under a limited number of repeated loading operations, and the number of rollers can be directly confirmed by visual means, without manual counting or repeated confirmation, which is one of the design points to ensure efficiency.

[0026] The guide pin grooves on the pallet allow for direct dumping and adding of roller parts. The angled guide pin grooves (U-shaped grooves) can automatically limit the direction of the rollers and can be directly smoothed by hand, allowing the rollers to be arranged in order, saving time and effort.

[0027] The arc edge design at one end of the feeding tube can cooperate well with the slider groove, which can easily and effectively limit the sleeve and make the filling go smoothly; and the sleeve plug is designed to facilitate the limit before roller filling during installation. If it is removed, the roller can fall and be filled smoothly, thereby improving the efficiency of assembly. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] A roller slider assembly fixture comprises a tray 1, a feeding fixture 2 and a feeding tube 3.

[0040] The top and bottom surfaces of the tray 1 are both provided with mounting grooves 10 and slide grooves 12. The slide grooves 12 are provided along the length direction of the tray 1 (x-axis direction). Both ends of the slide grooves 12 pass through the side walls of the tray 1. A plurality of partitions 13 are provided in the mounting grooves 10 along the x-axis direction. The ends of the partitions 13 abut against the side walls of the mounting grooves 10. The partitions 13 and the tray 1 are fixedly connected. Preferably, the partitions 13 and the tray 1 are integrally formed, and guide column grooves 11 are formed between adjacent partitions 13. When a plurality of rollers are located in the guide column grooves 11, the plurality of rollers are arranged in the guide column grooves 11 along the axial direction of the rollers themselves. When a plurality of rollers are located in the slide grooves 12, the plurality of rollers are arranged in the slide grooves 12 along the radial direction of the rollers, that is, there may be an angle between the length direction of the guide column grooves 11 and the length direction of the slide grooves 12.

[0041] In this embodiment, the length direction of the partition 13 is perpendicular to the length direction of the tray 1, the length direction of the guide column groove 11 is arranged along the y-axis direction, the guide column groove 11 is connected to the slide groove 12, and the end surface area of ​​one end of the partition 13 close to the notch of the mounting groove 10 is smaller than the end surface area of ​​the other end of the partition 13, so that the cross-section of the guide column groove 11 in the xz plane is U-shaped, the width of the U-shaped groove along the x-axis direction is d, the end surface diameter of the roller is D, the axial length of the roller is H, D≤d≤1.2D, and the width of the slide groove 12 along the y-axis direction is h, H≤h≤1.2H

[0042] Arrange multiple rollers in the guide column groove 11 so that the axial direction of the rollers is consistent with the length direction of the guide column groove 11, and the rollers in the guide column groove 11 are pushed toward the slide groove 12 so that the multiple rollers are arranged in the slide groove 12 along the x-axis direction.

[0043] The feeding fixture 2 is plugged into the tray 1. The side of the feeding fixture 2 facing the tray 1 is connected with a positioning column 21. The side wall of the tray 1 is provided with a positioning groove adapted to the positioning column 21. The positioning column 21 cooperates with the positioning groove so that the feeding fixture 2 and the tray 1 are precisely matched. The feeding fixture 2 is provided with a receiving groove 20 for placing the feeding tube 3. The feeding tube 3 is placed in the receiving groove 20. The chute 12 is opposite to the channel inside the feeding tube 3. The axial direction of the feeding tube 3 is arranged along the x direction. The inner side wall of the feeding tube 3 keeps the same height as the bottom of the chute 12, which is convenient for the loading of the roller. When using, you only need to insert the roller and press it into the fixture to quickly position it. At this time, the rollers arranged in the chute 12 can be smoothly pushed into the feeding tube 3.

[0044] A through opening is provided on the side wall of the feeding tube 3 at one end away from the tray 1, and a plunger 30 is inserted on the feeding tube 3. The plunger 30 is inserted in the through opening, and the plunger 30 presses against the roller in the feeding tube 3, so that the roller is not easy to fall out of the feeding tube 3.

[0045] An abutment surface 31 is provided at the end of the feeding tube 3 away from the tray 1. The abutment surface 31 is arranged in an arc shape, and the radius of the arc surface is Ry. The end of the feeding tube 3 provided with the abutment surface 31 is connected with a plug-in portion 32, and the plug-in portion 32 is arranged on the abutment surface 31. The end of the plug-in portion 32 away from the tray 1 does not exceed the outer edge of the end of the feeding tube 3. The end of the plug-in portion 32 away from the tray 1 is also arranged in an arc shape, so that the roller falls into the groove of the retaining frame 4 along its arc surface. The radius of the arc surface is Rx, and Ry is greater than Rx.

[0046] When the roller is installed in the cage 4, the abutting surface 31 is abutted against the arc surface on the cage 4, and the abutting surface 31 is tangent to the arc surface R at the end of the cage 4, that is, Ry is greater than R, the tangent point between the abutting surface 31 and the arc surface at the end of the cage 4 is point P, the distance between point P and the outer wall of the feeding tube 3 is A, and the distance between point P and the end surface of the feeding tube 3 is B. The size range of A is 3.3-3.5 mm, and the size range of B is 4.1-4.3 mm. The determination of these two sizes can ensure the position accuracy of the tangent point. Since the arc radius of the abutting surface 31 of the feeding tube 3 is large, there can be a margin at both ends to ensure that there is only one point in contact with the cage 4, and there will be no over-positioning; at the same time, the plug-in part 32 can be stuck between the two walls in the cage 4, and the spacing between the plug-in part 32 and the two walls in the cage 4 is about 1 mm, thereby limiting the position in the lateral direction. Through this cooperation, the position of the sleeve can be accurately determined to ensure that the roller smoothly enters the channel in the cage 4.

[0047] The implementation principle of this application is:

[0048] Insert the feeding fixture 2 onto the pallet 1, place the feeding tube 3 in the receiving groove 20, so that the internal channel of the feeding tube 3 is opposite to the slide groove 12, insert the plunger 30 on the feeding tube 3, place the roller in the guide column groove 11, smooth it with a scraper, and let the rollers be arranged in sequence. A row of rollers will enter the slide groove 12 from top to bottom and be arranged in a row, and then the rollers in the slide groove 12 are pushed into the feeding tube 3. It should be noted that the number of guide column grooves 11 on the same surface of the pallet 1 is a multiple of the number of rollers required for a channel on the retaining frame 4, thereby preventing unnecessary operations and improving efficiency.

[0049] The feeding tube 3 equipped with rollers is docked with the retaining frame 4, the abutting surface 31 is abutted with the arc surface on the retaining frame 4, the plug-in portion 32 is inserted into the retaining frame 4, and the plunger 30 is pulled out, so that the rollers can slide smoothly into the grooves in the retaining frame 4.

[0050] The width d of the guide slot 11 on the top and bottom of the tray 1 may be different, so that when installing another type of roller, the tray 1 only needs to be turned over and laid flat, and the roller can be pushed from right to left to load. No need to change the working direction, saving time.

[0051] In summary, the fixture has a simple structure and is made of light and cheap materials, but it can greatly improve assembly efficiency and ensure orderly production. By setting a guide column groove 11 on the side wall of the tray 1 that matches the number of rollers required for a single channel of the slider, the rollers can be loaded in an orderly and accurate manner under a limited number of repeated loading operations, and the number of rollers can be directly confirmed by visual means, without the need for manual counting or repeated confirmation, which is one of the design points to ensure efficiency.

[0052] The guide column groove 11 on the tray 1 satisfies the direct dumping and adding of roller parts. The angled groove can automatically limit the direction of the roller and can be directly smoothed by hand, so that the rollers can be arranged in order, which saves time and effort.

[0053] The arc edge design at one end of the feeding tube 3 can cooperate well with the slider groove, and the sleeve can be limited simply and effectively to ensure smooth loading. The sleeve plug is designed to facilitate the limiting of the roller before filling during installation. If it is removed, the roller can be dropped and filled smoothly, thereby improving the efficiency of assembly.

[0054] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
