Description

Technical Field

[0001] This utility model relates to the field of guide rail slide technology, and more specifically, to a cross roller slide. Background Technology

[0002] Cross roller slides are high-precision linear motion components. Their core advantage lies in achieving high rigidity, low friction, and precise guidance through cross-arranged rollers. The rollers are arranged perpendicularly at 90° between the guide rail and the slider, which can evenly bear multi-directional loads such as radial, axial, and overturning moments.

[0003] Currently, cross roller slides are typically equipped with micrometers for adjustment to meet various usage requirements. However, since micrometers are usually installed on one side of the cross roller slide, existing cross roller slides are bulky after the micrometer is installed, making them inconvenient to install and use. Moreover, after adjustment with the micrometer, screws are needed to lock and fix the slide, which is also inconvenient. Therefore, this utility model proposes a cross roller slide. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cross roller slide, which aims to solve the problems that the cross roller slide in the prior art is bulky after installing a micrometer, making it inconvenient to install and use. Moreover, after adjusting with a micrometer, the slide needs to be locked and fixed with screws, which is inconvenient for adjustment.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A cross roller slide includes a lower base and an upper base. The upper base is slidably connected to the lower base. Two V-shaped fixed guide rails are fixedly connected to the lower base. Two V-shaped sliding guide rails are fixedly connected inside the upper base, with the two fixed guide rails located inside the two sliding guide rails. Cross roller retainers are slidably connected between the two fixed guide rails and the two sliding guide rails. A worm gear is rotatably connected inside the lower base, with both ends of the worm gear extending movably to the symmetrical sides of the lower base. A worm wheel is rotatably connected inside the lower base and meshes with the worm gear. A toothed groove is provided on the top wall of the upper base, and the worm wheel meshes with the toothed groove. A scale is fixedly connected to both symmetrical ends of the lower base, and a graduation mark is fixedly connected to both symmetrical ends of the upper base, with the two graduation marks corresponding to the two scales.

[0009] As a preferred embodiment of this utility model, a lower screw assembly is threadedly connected between the lower base and the two V-shaped fixed guide rails, and an upper screw assembly is threadedly connected between the upper base and the two V-shaped sliding guide rails.

[0010] As a preferred embodiment of this utility model, the lower base is provided with four fixing holes, and the four fixing holes are evenly distributed at the four corners of the lower base.

[0011] As a preferred embodiment of this utility model, the top end of the upper base is provided with a threaded connection hole.

[0012] As a preferred embodiment of this utility model, the lower base has two positioning grooves, and two V-shaped fixed guide rails are respectively located in the two positioning grooves.

[0013] As a preferred embodiment of this utility model, both ends of the two V-shaped fixed guide rails and the two V-shaped sliding guide rails can be detachably connected with limit screws, and the eight limit screws correspond to the two cross roller retainers respectively.

[0014] As a preferred embodiment of this utility model, the upper base is provided with an oil injection hole, and the oil injection hole corresponds to two cross roller retainers.

[0015] As a preferred embodiment of this utility model, both ends of the worm gear are fixedly connected with anti-slip knobs, and the two anti-slip knobs are respectively located on the symmetrical sides of the lower base.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) In this solution, the upper base is slidably connected to the lower base through two V-shaped fixed guide rails, two V-shaped sliding guide rails and two cross roller cages. By rotating the worm, the worm wheel is rotated, and the worm wheel drives the upper base to slide on the lower base through the tooth groove for guidance adjustment. During the adjustment of the upper base, the adjustment position can be determined by the scale and scale mark. In this utility model, the worm wheel is driven by rotating the worm, and the worm wheel drives the upper base to complete the guidance adjustment through the tooth groove. The worm, worm wheel and tooth groove are all set inside the lower base and the upper base. Compared with the slide table with a micrometer installed on the outside, the cross roller slide table can reduce the space occupation while ensuring the adjustment effect. It is smaller in size and more convenient to install and use. Moreover, the worm and worm wheel have a certain self-locking effect. After the upper base is adjusted, it can remain stable in the current position. It does not need to frequently use screws to lock and fix the slide table, and the adjustment method is more convenient.

[0019] (2) In this scheme, when the upper base is adjusted by rotating the worm gear, the worm gear can be rotated from the rear end when the upper base moves forward, and from the front end when the upper base moves backward. The worm gear can be rotated from both ends, making the adjustment method of the upper base more user-friendly and convenient for operators. Attached Figure Description

[0032] Example:

[0033] Please see Figure 1-7 A cross roller slide includes a lower base 1 and an upper base 2. The upper base 2 is slidably connected to the lower base 1. Two V-shaped fixed guide rails 3 are fixedly connected to the lower base 1. Two V-shaped sliding guide rails 4 are fixedly connected inside the upper base 2, and the two V-shaped fixed guide rails 3 are located inside the two V-shaped sliding guide rails 4. Cross roller retainers 5 are slidably connected between the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4, respectively. A worm gear 6 is rotatably connected inside the lower base 1, and the two ends of the worm gear 6 movably extend to the symmetrical sides of the lower base 1. A worm wheel 7 is rotatably connected inside the lower base 1, and the worm wheel 7 meshes with the worm gear 6. A toothed groove 8 is provided on the top wall of the upper base 2, and the worm wheel 7 meshes with the toothed groove 8. A scale 9 is fixedly connected to both symmetrical ends of the lower base 1, and a scale mark 10 is fixedly connected to both symmetrical ends of the upper base 2, and the two scale marks 10 correspond to the two scales 9, respectively.

[0034] In this embodiment, two V-shaped fixed guide rails 3 are fixedly connected to the lower base 1. Two crossed roller retainers 5 are respectively placed in the V-shaped grooves at opposite ends of the two V-shaped fixed guide rails 3. By placing two V-shaped sliding guide rails 4 on both sides of the two V-shaped fixed guide rails 3, the ends of the two V-shaped sliding guide rails 4 are aligned with the ends of the two V-shaped fixed guide rails 3. The two V-shaped sliding guide rails 4 respectively clamp the two crossed roller retainers 5 using the V-shaped grooves, so that the two crossed roller retainers 5 are slidably connected between the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4. The upper base 2 slides to the outside of the two V-shaped sliding guide rails 4 to the top of the lower base 1, with the ends of the upper base 2 aligned with the ends of the lower base 1. By fixing two V-shaped sliding guide rails 4 inside, a sliding connection with the lower base 1 is achieved to form a cross roller slide. When the cross roller slide needs to be used on the equipment, the lower base 1 is installed on the required equipment, and the worm gear 6 is rotated to make the worm wheel 7 rotate. The worm wheel 7 drives the upper base 2 to move through the tooth groove 8. The upper base 2 is precisely guided and adjusted for the components on the equipment through the sliding connection between the two V-shaped fixed guide rails 3, the two V-shaped sliding guide rails 4 and the two cross roller retainers 5. During the movement of the upper base 2, the two scale marks 10 will move. The sliding distance of the upper base 2 can be observed from the side through the two scales 9 and the two scale marks 10, ensuring that the upper base 2 moves accurately to the required position.

[0035] Specifically, a lower screw assembly 11 is threadedly connected between the lower base 1 and the two V-shaped fixed guide rails 3, and an upper screw assembly 12 is threadedly connected between the upper base 2 and the two V-shaped sliding guide rails 4.

[0036] In this embodiment, two V-shaped fixed guide rails 3 are fixedly connected to the lower base 1 by a lower screw assembly 11, and two V-shaped sliding guide rails 4 are fixedly connected to the upper base 2 by an upper screw assembly 12. The lower screw assembly 11 and the upper screw assembly 12 keep the connection between the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4 and the lower base 1 and the upper base 2 stable.

[0037] Specifically, the lower base 1 has four fixing holes 13, and the four fixing holes 13 are evenly distributed at the four corners of the lower base 1.

[0038] In this embodiment, the lower base 1 is installed by four fixing holes 13 with screws, and can be fixedly connected to the required equipment.

[0039] Specifically, a threaded connection hole 14 is provided at the top of the upper base 2.

[0040] In this embodiment, the threaded connection hole 14 is used to connect the components on the equipment, so that the upper base 2 can guide and adjust the components on the equipment.

[0041] Specifically, two positioning grooves 15 are provided on the lower base 1, and two V-shaped fixed guide rails 3 are located in the two positioning grooves 15 respectively.

[0042] In this embodiment, the two positioning grooves 15 are used to position the two V-shaped fixed guide rails 3 so that the two V-shaped fixed guide rails 3 can be accurately installed on the lower base 1 with the screw assembly 11.

[0043] Specifically, both ends of the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4 can be detachably connected to limit screws 16, and the eight limit screws 16 correspond to the two cross roller retainers 5 respectively.

[0044] In this embodiment, the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4 can slide smoothly after clamping the two cross roller retainers 5. The two cross roller retainers 5 slide stably in the V-shaped grooves between the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4. The eight limiting screws 16 are used to restrict the V-shaped grooves on the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4 to prevent the two cross roller retainers 5 from falling out of the V-shaped grooves.

[0045] Specifically, the upper base 2 is provided with an oil injection hole 17, and the oil injection hole 17 corresponds to the two cross roller cages 5.

[0046] In this embodiment, the oil injection hole 17 extends from the surface of the upper base 2 into the interior and corresponds to the two crossed roller cages 5. The oil injection hole 17 facilitates the injection of oil into the interior of the upper base 2. The oil injection position corresponds to the two crossed roller cages 5 for lubrication, which can improve the sliding effect between the two V-shaped fixed guide rails 3 and the two V-shaped sliding guide rails 4.

[0047] Specifically, both ends of the worm gear 6 are fixedly connected with anti-slip knobs 18, and the two anti-slip knobs 18 are located on the symmetrical sides of the lower base 1.

[0048] In this embodiment, the upper base 2 can be guided and adjusted by rotating both ends of the worm gear 6. The two anti-slip knobs 18 are set at both ends of the worm gear 6 to provide an anti-slip effect, making it easier to rotate the worm gear 6.

[0049] Working principle: The lower base 1 is installed on the equipment, and the parts on the equipment that need to be guided and adjusted are installed on the upper base 2. By rotating the worm gear 6, the worm wheel 7 is rotated. The worm wheel 7 moves the upper base 2 through the tooth groove 8. The upper base 2 is stably driven to guide and adjust the equipment parts on the lower base 1 through the sliding connection of two V-shaped fixed guide rails 3, two V-shaped sliding guide rails 4 and two cross roller retainers 5. During the movement of the upper base 2, it will drive the two scale marks 10 to move. The sliding distance of the upper base 2 can be observed from the side through the two scales 9 and the two scale marks 10, ensuring that the upper base 2 moves accurately to the required position.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
