Description

Technical Field

[0001] This utility model relates to the field of slide mechanism technology, and in particular to a novel gear rack slide module. Background Technology

[0002] In the process of industrial modernization, people's requirements for the capabilities of production equipment are constantly increasing. In traditional slide mechanisms, the drive is mainly achieved through a screw and guide rail system. While this method ensures the accuracy of the slide's operation, it also severely limits its operating speed and stroke.

[0003] Currently, some companies have made improvements to address this issue, proposing rack and pinion slide mechanisms. These mechanisms offer higher stability and faster operating speeds than screw-guide slides. However, the working environment of rack and pinion slide mechanisms is generally more complex, making them susceptible to impurities that can affect their normal operation. Furthermore, rack and pinion slide mechanisms are typically used in high-load applications, thus requiring high load capacity. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model proposes a new type of gear rack slide module, which aims to solve the problem that dust and impurities are easily introduced into the gear rack slide in harsh environments, affecting the normal operation of the device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel gear rack slide module, comprising a slide frame body, a slide groove provided along the length direction on the upper surface of the slide frame body, guide rails provided on both sides of the slide groove, the guide rails being slidably engaged with the slide via a slider, a rack being fixedly installed on one side of the slide groove, a driving device provided on the slide, a transmission gear meshing with the rack being provided at the output end of the driving device, and accordion covers provided at both the front and rear ends of the slide, one end of the accordion cover being fixedly connected to one end of the slide frame body, and the other end being fixedly connected to one end of the slide.

[0006] Based on the above, during the process of the drive device moving the slide, the bellows cover also moves, keeping the slide in a closed state, which can effectively prevent dust from entering, making the slide move more smoothly, improving operating efficiency and increasing the service life of this utility model.

[0007] Furthermore, guide grooves are provided on both sides of the upper end of the slide, and sliding blocks that slide in cooperation with the guide grooves are provided on the lower ends of both sides of the bellows cover.

[0008] Based on the above, the bellows cover slides with the guide groove through an inner snap-fit ​​design, making the installation structure compact, occupying little space, and making installation more convenient.

[0009] Furthermore, sheet metal sealing plates are provided on both sides of the accordion cover, and the sheet metal sealing plates are fixedly fitted with the slide frame body.

[0010] Based on the above, the accordion cover stretches and folds during the movement of the slide, which can easily cause injury to workers. The sheet metal sealing plate can block the two sides of the accordion cover, making the operation of this utility model safer and more secure.

[0011] Furthermore, positioning sensors are provided at both ends of the outer side of the slide frame body. The positioning sensors are located within the stroke of the guide slide rail. Both ends of the guide slide rail are provided with stroke limit plates, which are laterally positioned on the slide groove.

[0012] Based on the above, the positioning sensor is used to detect and control the travel of the slide. When the slide reaches the position of the positioning sensor, the drive device stops running, causing the slide to stop and preventing the slide from exceeding its travel. At the same time, if the drive device malfunctions and cannot stop running in time, the travel limit plate can block the movement of the slide and prevent damage to the module.

[0013] Furthermore, the travel limit plate is provided with a buffer device on the side biased towards the slide.

[0014] Based on the above, the buffer device can prevent the slide from directly colliding with the travel limit plate, thus protecting the slide.

[0015] Furthermore, the width of the slide frame body is 250mm to 300mm, and the height is 100mm to 120mm.

[0016] Based on the above, the width of the slide frame body is wider than that of a conventional slide frame, which improves the load-bearing capacity of this utility model.

[0017] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0024] like Figure 1 As shown, a novel gear and rack slide module includes a slide frame body 1. A slide groove 2 is provided along the length of the upper surface of the slide frame body 1. Guide rails 3 are provided on both sides of the slide groove 2. A slide 5 is slidably engaged with the guide rails 3 via sliders 4. A rack 6 is fixedly installed on one side of the slide groove 2. A drive device 7 is provided on the slide 5. A transmission gear 8 meshes with the rack 6 at the output end of the drive device 7. Bellows covers 9 are provided at both the front and rear ends of the slide 5. One end of the bellows cover 9 is fixedly connected to one end of the slide frame body 1, and the other end is fixedly connected to one end of the slide 5. During the movement of the slide 5 driven by the drive device 7, the bellows cover 9 also moves. The bellows cover 9 engages with the upper end of the slide groove 2, forming a closed space that effectively prevents dust from entering, making the movement of the slide 5 smoother, improving operating efficiency, and increasing the service life of this invention.

[0025] Preferably, guide grooves 10 are provided on both sides of the upper end of the slide groove 2, and sliding blocks 15 that slide in cooperation with the guide grooves 10 are provided on the lower ends of both sides of the bellows cover 9. The bellows cover 9 slides in cooperation with the guide grooves 10 through an inward snap-fit ​​mechanism. Traditional bellows covers are mainly installed by means of an outer cover. Compared with the traditional installation method, the installation structure of this utility model is compact, occupies less space, and is more convenient to install.

[0026] Preferably, sheet metal sealing plates 11 are also provided on both sides of the accordion cover 9, and the sheet metal sealing plates 11 are fixedly engaged with the slide frame body 1. The accordion cover 9 stretches and folds during the movement of the slide 5, which can easily cause injury to the workers. The sheet metal sealing plates 11 can block the sides of the accordion cover 9, making the operation of this utility model safer and more secure.

[0027] Preferably, position sensing devices 12 are provided at both ends of the outer side of the slide body 1. The position sensing devices 12 are located within the stroke of the guide slide rail 3. Both ends of the guide slide rail 3 are provided with stroke limiting plates 13, which are laterally arranged on the slide groove 2. The position sensing devices 12 are used to detect and control the stroke of the slide 5. When the slide 5 reaches the position of the position sensor, the drive device 7 stops running, stopping the slide 5 and preventing the slide 5 from exceeding its stroke. At the same time, if the drive device 7 malfunctions and cannot stop running in time, the stroke limiting plates 13 can block the movement of the slide 5 and prevent damage to the module.

[0028] Preferably, the travel limiting plate 13 is provided with a buffer device 14 on the side biased towards the slide table 5. The buffer device 14 can prevent the slide table 5 from directly colliding with the travel limiting plate 13, thus protecting the slide table 5.

[0029] Preferably, the width of the slide frame body 1 is 270mm and the height is 110mm, so that the horizontal operating load capacity of this utility model reaches 500KG and the vertical operating load capacity reaches 100KG.

[0030] The specific implementation of this embodiment is as follows: The driving device 7 drives the transmission gear 8 to mesh with the rack 6, and the slide table 5 moves horizontally under the drive of the transmission gear 8. During the movement of the slide table 5, the bellows covers 9 connected to both ends of the slide table 5 also stretch, contract, and fold. The bellows covers 9 can isolate dust and debris, preventing the parts in the slide groove 2 from being contaminated and damaged, thus affecting the normal production of the workshop. The bellows covers 9 slide with the guide groove 10 through an inward snap-fit, making the fit between the structures more compact and reducing the space occupied.

[0031] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model.
