Description

Technical Field

[0001] This utility model relates to the field of slide guide devices, and in particular to a transverse slide guide device. Background Technology

[0002] In the field of mechanical design, especially in automated equipment, machine tools and precision transmission systems, the transverse slide guide device is a core component for achieving precise linear motion. Its performance directly affects the motion accuracy, stability and service life of the equipment. Its core function is to constrain the slide to move along a preset transverse trajectory. By limiting the excess degrees of freedom of the slide, it ensures that the slide maintains a high-precision linear motion posture when carrying workpieces, tools or detection mechanisms. At the same time, it reduces component friction loss and extends the service life of the equipment by optimizing the design of friction pairs. However, the existing assembly process has obvious technical pain points. Because the slide needs to be precisely connected with the transmission components (such as ball screws and gear racks) in the guide device, and the guide element often uses end limiting structures (such as end caps and blocks) for axial positioning, the operator must first disassemble the end limiting structure of the guide device to fully open the axial channel of the guide element, then connect the slide with the transmission component, and finally reinstall the end limiting structure. This is not only cumbersome and time-consuming, but also requires sufficient operating space for the installation and disassembly of fixed positions. In compact equipment or scenarios with dense layout of multiple components, space constraints can easily lead to a significant reduction in assembly efficiency and even increase the risk of component collision damage, making it difficult to meet the requirements of efficient assembly and compact design of automated equipment. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A transverse slide guide device includes two support end frames and two track plates. Two split slides are disposed between the two track plates and are engaged with the outer sides of the two track plates. A lead screw is rotatably connected between the two support end frames and is located between the two track plates. A drive unit for driving the lead screw is installed on the outer side of one of the support end frames. Threaded holes are opened on opposite sides of the two split slides, and the lead screw is threaded between the two threaded holes. An end plate is disposed between the two split slides. The end plate includes a first top plate and a second top plate, which are respectively installed on the top of the corresponding split slide. The split slides are detachably connected through the first top plate and the second top plate.

[0005] As a further embodiment of this utility model: two grooves are provided on each of the two split slides on opposite sides, and the split slides are engaged with one side of the two track plates through the two grooves.

[0006] As a further embodiment of this utility model: a plurality of spherical rolling elements are embedded in the inner walls of the four grooves, and the spherical rolling elements are slidably connected to the corresponding end face of the track plate.

[0007] As a further embodiment of this utility model: two first insert rods are installed at one end of the first top plate, and a second insert rod is installed at one end of the second top plate. A first insertion hole is opened at one end of the first top plate to connect with the second insert rod, and two second insertion holes are opened at one end of the second top plate to connect with the first insert rod.

[0008] As a further embodiment of this utility model: a fastening screw is rotatably connected to the inner wall of the first top plate, the fastening screw is threadedly connected to the inner wall of the second insert rod, and a knob is installed at one end of the fastening screw, the knob being rotatably connected to one end of the first top plate.

[0009] As a further embodiment of this utility model: a limiting rod and a guide ring are provided on one side of the knob. The limiting rod is slidably connected to the inner wall of the guide ring. A fixing ring and a limiting plate are respectively installed on the side wall and one end of the limiting rod. The guide ring is located between the fixing ring and the limiting plate. Several insertion slots are opened on the side wall of the knob, and the limiting rod is inserted into the inner wall of the insertion slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By adopting a split slide structure, during assembly, it is not necessary to disassemble the limiting structure at the end of the guide device to open the axial channel of the guide element. Instead, the two split slides can be directly snapped onto the outside of the track plate from the side, thereby achieving a detachable connection between the split slides and completing the assembly of the end plate and the split slides. After that, it is only necessary to connect the lead screw with the threaded holes on the two split slides. The entire assembly process is greatly simplified, eliminating the need for complex end disassembly and reassembly procedures. Moreover, this side snap-fit ​​and component installation method greatly reduces the requirements for installation space. Even in compact equipment or scenarios with densely packed multi-component layouts, assembly can be carried out smoothly, effectively improving assembly efficiency and reducing the risk of component collision damage due to space constraints. This well meets the needs of efficient assembly and compact design of automated equipment.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-5A transverse slide guide device according to an embodiment of the present invention includes two support end frames 1 and two track plates 11. Two split slides 2 are arranged between the two track plates 11. The two split slides 2 are engaged and connected to the outside of the two track plates 11. A lead screw 12 is rotatably connected between the two support end frames 1. The lead screw 12 is located between the two track plates 11. A drive part 13 for driving the lead screw 12 is installed on the outside of one of the support end frames 1. Threaded holes 21 are opened on opposite sides of the two split slides 2. The lead screw 12 is threaded between the two threaded holes 21. An end plate 3 is arranged between the two split slides 2. The end plate 3 includes a first top plate 31 and a second top plate 32. The first top plate 31 and the second top plate 32 are respectively installed on the top of the corresponding split slides 2. The split slides 2 are detachably connected through the first top plate 31 and the second top plate 32.

[0021] During operation, the drive unit 13 starts, and its output power is transmitted to the lead screw 12, causing the lead screw 12 to rotate between the two support end frames 1. Since the lead screw 12 is threadedly engaged with the threaded holes 21 on the opposite side of the two split slide blocks 2, the rotation of the lead screw 12 is converted into the transverse linear movement of the two split slide blocks 2 along the track plate 11. The two track plates 11 act as guides and constraints on the split slide blocks 2, limiting the unnecessary degrees of freedom such as translation in non-transverse directions and rotation around each coordinate axis during the movement of the slide blocks. This ensures that the split slide blocks 2 can move accurately along the preset transverse trajectory. Then, through the first top plate 31 and the second top plate 32 respectively installed on the top of the corresponding split slide blocks 2, the end plate 3 is driven to achieve stable and high-precision transverse movement to meet the movement requirements of carrying workpieces, tools, or inspection mechanisms. At the same time, the friction pairs between the components of the device are optimized to effectively reduce friction loss during the movement process, which is conducive to extending the overall service life of the equipment. This device adopts the structure of split slide blocks 2, and the end plate 3 is made of materials that can be separately installed. The assembly consists of a first top plate 31 and a second top plate 32. During assembly, there is no need to disassemble the limiting structure at the end of the guide device to open the axial channel of the guide element. Instead, the two split slides 2 can be directly snapped onto the outside of the track plate 11 from the side. Then, the first top plate 31 and the second top plate 32 are respectively installed on the top of the corresponding split slides 2, thereby realizing the detachable connection between the split slides 2 and completing the assembly of the end plate 3 and the split slides 2. After that, it is only necessary to connect the lead screw 12 with the threaded holes 21 on the two split slides 2. The entire assembly process is greatly simplified, eliminating the need for complex end disassembly and reassembly procedures. Moreover, this side snapping and component installation method greatly reduces the requirements for installation space. Even in compact equipment or scenarios with dense multi-component layouts, assembly can be carried out smoothly, effectively improving assembly efficiency and reducing the risk of component collision damage due to space constraints. It well meets the needs of efficient assembly and compact design of automated equipment.

[0022] Further as Figure 1-5 As shown, each of the two split slide blocks 2 has two grooves 22 on its opposite side. The split slide blocks 2 are engaged with one side of the two track plates 11 through the two grooves 22. During operation, the grooves 22 and the track plates 11 form a precise fit, which further strengthens the guiding constraint on the split slide blocks 2 and restricts its other degrees of freedom, such as vertical movement, left and right offset and rotation, except for lateral translation during the movement. This ensures that the slide blocks move laterally along the track plates 11 stably and with high precision, and improves the rigidity and stability of the overall movement.

[0023] Further as Figure 1-5 As shown, several spherical rolling elements 221 are embedded in the inner walls of the four grooves 22. The spherical rolling elements 221 are slidably connected to the end face of the corresponding track plate 11. When the split slide 2 moves laterally along the track plate 11, the spherical rolling elements 221 roll between the grooves 22 and the track plate 11, converting the sliding friction between the split slide 2 and the track plate 11 into rolling friction. This significantly reduces the frictional resistance during relative movement, making the slide move more smoothly and respond more sensitively. At the same time, it reduces frictional wear and helps extend the service life of the components. In addition, the multi-point contact between the spherical rolling elements 221 and the track plate 11, combined with the groove 22 structure, can continuously maintain precise guiding constraints on the slide, ensuring that the stability and accuracy of the slide are not affected by changes in the friction mode during movement.

[0024] Further as Figure 1-5 As shown, one end of the first top plate 31 is equipped with two first insert rods 311, and one end of the second top plate 32 is equipped with a second insert rod 321. One end of the first top plate 31 has a first insertion hole 312 that mates with the second insert rod 321, and one end of the second top plate 32 has two second insertion holes 322 that mate with the first insert rods 311. The plug-in design ensures that the first top plate 31 and the second top plate 32 are precisely aligned and firmly connected, so that the two split slides 2 form an integral force-bearing structure through the end plate 3, maintaining synchronization when moving with the lead screw 12, and avoiding relative displacement from affecting the motion accuracy. At the same time, the plug-in structure facilitates quick assembly and disassembly. During the assembly stage, the first top plate 31 and the second top plate 32 can be installed on the corresponding split slides 2 respectively, and then the overall assembly can be completed by connecting the insert rods and the insertion holes, without the need for complicated tools, further improving the ease of assembly.

[0025] Further as Figure 1-5As shown, a fastening screw 4 is rotatably connected to the inner wall of the first top plate 31. The fastening screw 4 is threadedly connected to the inner wall of the second insertion rod 321. A knob 41 is installed at one end of the fastening screw 4, and the knob 41 is rotatably connected to one end of the first top plate 31. When the first insertion rod 311 and the second insertion rod 321 are inserted into their corresponding insertion holes, rotating the knob 41 at one end of the first top plate 31 will drive the fastening screw 4 on its inner side to rotate synchronously. Since the fastening screw 4 is threadedly connected to the inner wall of the second insertion rod 321, as the screw rotates, it will generate an axial locking force at the insertion part of the first top plate 31 and the second top plate 321, thereby firmly fixing the two together and preventing relative loosening. During operation, this structure retains the precise alignment function of the plug-in fit and enhances the connection rigidity through threaded fastening, ensuring that the two split slides 2 can form a stable whole through the end plate 3 when moving at high speed or bearing load, avoiding movement deviation caused by connection gaps; at the same time, the setting of the knob 41 makes disassembly and assembly operations without special tools, and fastening and loosening can be achieved by turning, further improving the convenience of assembly and maintenance.

[0026] Further as Figure 1-5 As shown, a limit rod 42 and a guide ring 43 are provided on one side of the knob 41. The limit rod 42 is slidably connected to the inner wall of the guide ring 43. A fixing ring 421 and a limit plate 422 are respectively installed on the side wall and one end of the limit rod 42. The guide ring 43 is located between the fixing ring 421 and the limit plate 422. Several insertion slots 411 are opened on the side wall of the knob 41, and the limit rod 42 is inserted into the inner wall of the insertion slots 411. After the first top plate 31 and the second top plate 32 are fastened by rotating the fastening screw 4 through the knob 41, the limit rod 42 is pushed to slide along the inner wall of the guide ring 43. A damping pad is provided on the inner wall of the guide ring 43 to increase the friction between it and the limiting rod 42. The guide ring 43 constrains the sliding direction of the limiting rod 42. At the same time, the fixing ring 421 and the limiting plate 422 prevent the limiting rod 42 from coming out of the guide ring 43 until one end of the limiting rod 42 is inserted into the corresponding socket 411 on the side wall of the knob 41. At this time, the limiting rod 42 restricts the rotation of the knob 41 through the socket 411, thereby preventing the fastening screw 4 from loosening due to factors such as equipment vibration during operation, and ensuring that the connection between the first top plate 31 and the second top plate 32 remains firm. When disassembly or adjustment is required, simply pull the limiting rod 42 in the opposite direction to disengage it from the socket 411 to release the limitation on the knob 41. Rotating the knob 41 again will loosen the fastening screw 4. The entire limiting and unlocking process does not require special tools, making it convenient to operate and providing a reliable anti-loosening effect.

[0027] The working principle of this utility model is as follows: When the transverse slide guide device is working, the drive unit 13 drives the lead screw 12 between the support end frame 1 to rotate. The lead screw 12 engages with the threaded holes 21 of the two split slides 2, driving the slides to move laterally along the track plate 11. The split slides 2 engage with the track plate 11 through the groove 22. The spherical rolling body 221 in the groove 22 converts sliding friction into rolling friction, which strengthens the guiding constraint, restricts unnecessary degrees of freedom, and reduces friction loss. The first top plate 31 and the second top plate 32 at the top of the two slides are precisely connected by inserting the first insertion rod 311 and the second insertion rod 321 into the corresponding insertion holes. Rotating the knob 41 drives the fastening screw 4 to engage with the second insertion rod 321 through threaded engagement, locking the two together. Then, the limiting rod 42 is pushed to slide along the guide ring 43 and insert into the knob 41 insertion port 411 to prevent the screw from loosening and ensure that the end plate 3 drives the slides to move stably and synchronously. During assembly, the slide is snapped into place from the side of the track plate 11, and the top plate components are inserted and secured. There is no need to disassemble the end structure, which simplifies the operation, reduces space requirements, and solves the problems of cumbersome assembly and limited space in traditional assembly.
