Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a slide table transmission assembly and a wood sawing device. Background Technology

[0002] Currently, wood sawing equipment is generally equipped with a slide table transmission assembly, which mainly includes a slider, guide rail, and transmission components. The transmission components are responsible for transmitting power to the slide table. The slider at the bottom of the slide table slides in cooperation with the guide rail, thereby driving the slide table to reciprocate, realizing rapid wood feeding and return movements, shortening the cutting cycle, achieving continuous operation of the wood sawing equipment, and greatly reducing manual operation time and labor intensity.

[0003] However, the sawing process generates a large amount of wood chips. If the slider, guide rail, and transmission components are not protected, the wood chips can easily enter the gaps between the components, causing jamming and seriously affecting the normal operation of the entire slide table transmission assembly. In the existing installation process of the slide table transmission assembly, since the installation positions of the slider, guide rail, and transmission components are relatively scattered, it is necessary to install dust covers or protective covers on each component one by one. During installation, multiple protective covers need to be precisely aligned with each component, which is quite inconvenient and consumes a lot of time and effort. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a slide table transmission assembly, which integrates the sliding mechanism and the transmission mechanism in a protective cavity at the bottom of the slide table. In this way, the sliding mechanism and the transmission mechanism can be protected as a whole, avoiding jamming during operation, and there is no need to set up multiple protective covers separately, making the installation process simple and quick.

[0005] The second objective of this utility model is to provide a wood sawing device, wherein the slide transmission assembly can protect the sliding mechanism and transmission mechanism at the bottom during the movement process, so as to avoid jamming during operation.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A slide table transmission assembly, comprising:

[0008] The slide block is provided with a protective cavity;

[0009] A sliding mechanism is provided in the protective cavity. The sliding mechanism includes a first sliding part and a second sliding part. The first sliding part and the second sliding part are slidably engaged to guide the slide block to move in a straight line direction.

[0010] A transmission mechanism is provided inside the protective cavity; the transmission mechanism includes a lead screw and a lead screw nut, the lead screw being rotatably mounted in the protective cavity; the lead screw nut is threaded onto the lead screw and connected to the slide block; the lead screw nut is used to reciprocate along the axial direction of the lead screw under the guidance of the sliding mechanism when the lead screw rotates, so as to guide the movement of the slide block.

[0011] Furthermore, it also includes a protective cover, one end of which passes through the slide block, and the other end of which extends along the movement direction of the slide block, with the protective cavity formed inside the protective cover; the slide block is used to slide and engage with the outer periphery of the protective cover during movement.

[0012] Furthermore, the protective cover includes a connecting plate and two baffles. The connecting plate is connected between the two baffles and partially encloses the protective cavity with the two baffles. The slide is provided with a connecting groove, which includes a first groove segment and two second groove segments. The two second groove segments are respectively located on both sides of the slide and are respectively used to pass through the two baffles. When subjected to force, the two baffles extend into the second groove segments and are used to slide and cooperate with the inner wall of the second groove segments when the slide moves.

[0013] The first slot is connected to two second slots respectively, and the connecting plate is used to be located in the first slot when the baffle extends into the second slot.

[0014] Furthermore, the slide has grip notches on both sides, and the grip notches are connected to the connecting groove.

[0015] Furthermore, the protective cover also includes a cover plate, which is detachably connected to the connecting plate after the protective cover extends into the connecting groove, so as to cover one end of the protective cover near the slide.

[0016] Furthermore, the slide block is also provided with a number of reinforcing ribs, which are spaced apart on the top wall of the first groove section.

[0017] Furthermore, the protective cover includes at least two support arms, each support arm including a first plate segment and a second plate segment. The first plate segment is connected to the bottom of the connecting plate, and the second plate segment is perpendicular to the first plate segment and connected to the first plate segment. The second plate segment is used to connect to an external structure.

[0018] Furthermore, the first sliding part is a slider disposed at the bottom of the slide block, and the second sliding part is a guide rail disposed in the protective cavity, with the slider and the guide rail slidingly engaged.

[0019] The technical solution adopted for the second objective of this utility model is:

[0020] A wood sawing device includes a base, a drive unit, and the aforementioned slide transmission assembly. The slide is used to hold a workpiece and to convey the workpiece along a conveying direction when the lead screw rotates. The drive unit is used to drive the lead screw to rotate.

[0021] Furthermore, the machine base is also provided with at least two guide seats, which are spaced apart and located inside the protective cavity. The two guide seats are provided with through holes, and the two ends of the lead screw are respectively passed through the two through holes.

[0022] In summary, the slide table transmission assembly and wood sawing device provided by this utility model have the following technical effects: In specific use, the workpiece is placed on the slide, and the driving component drives the lead screw to rotate. During the rotation of the lead screw, the lead screw nut moves back and forth along the axis of the lead screw, thereby driving the slide to move. At the same time, the first sliding part and the second sliding part slide together to provide guidance for the movement of the slide, so that the slide stably transports the workpiece to the cutting station in a predetermined direction, effectively avoiding the slide from deviating during the movement.

[0023] Furthermore, since the sliding mechanism and the transmission mechanism are both housed in the protective cavity at the bottom of the slide, they can be protected as a whole without the need for multiple protective covers, making the installation process simple and quick.

[0030] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Example 1,

[0034] See Figs. 1 to 4 This utility model discloses a slide table transmission assembly, including: a slide 10, a sliding mechanism, and a transmission mechanism 40. The slide 10 is provided with a protective cavity, and the sliding mechanism and the transmission mechanism 40 are both located in the protective cavity. Specifically, the sliding mechanism includes a first sliding part and a second sliding part, which slide in cooperation with each other to guide the slide 10 to move in a straight line. The transmission mechanism 40 includes a lead screw 41 and a lead screw nut 42. The lead screw 41 is rotatably mounted in the protective cavity, and the lead screw nut 42 is threaded onto the lead screw 41 and connected to the slide 10. When the lead screw 41 rotates, the lead screw nut 42 reciprocates along the axial direction of the lead screw 41 under the guidance of the sliding mechanism to guide the slide 10 to move.

[0035] Based on the above structure, during assembly, the first sliding part can be a slider 30 or a pulley located at the bottom of the slide block 10, while the second sliding part can be a guide rail 31 or a slide rail extending along the axial direction of the protective cavity. The second sliding part is correspondingly arranged with the first sliding part so that the two can slide together. When the lead screw 41 rotates, the lead screw nut 42 reciprocates along the axial direction of the lead screw 41. Since the lead screw nut 42 is connected to the slide block 10, the slide block 10 can also reciprocate along the axial direction of the lead screw 41. At this time, due to the sliding cooperation between the first sliding part and the second sliding part, the slide block 10 moves more smoothly in the process of reciprocating along the axial direction of the lead screw 41. Under the guidance of the second sliding part, the lead screw 41 can move in a predetermined direction, making its movement trajectory stable and preventing the slide block 10 from deviating during the movement, thus improving the stability of the movement of the slide block 10.

[0036] In addition, since both the sliding mechanism and the transmission mechanism 40 are located inside the protective cavity, the cavity wall of the protective cavity can provide overall protection for the sliding mechanism or the transmission mechanism 40 during operation, thereby effectively preventing dust or impurities from entering during equipment processing and reducing the risk of the sliding mechanism or the transmission mechanism 40 getting stuck during operation.

[0037] Compared to the traditional method, which requires installing multiple independent protective covers 20 for each part of the transmission mechanism 40 and the sliding mechanism, and each protective cover 20 needs to be individually positioned and fixed, aligned with each component of the transmission mechanism 40 and the sliding mechanism to ensure proper protection, this method only requires repeatedly adjusting the position, which is cumbersome and time-consuming. In this implementation, the protective cavity is aligned with the area where the transmission and sliding mechanisms are located, and the positioning is completed in one go, avoiding the complicated operation of positioning multiple protective covers 20 separately. The installation process is convenient, time-saving and labor-saving.

[0038] It should be noted that in this embodiment, the slide 10 can be integrally molded into the shape of a cover, so that a protective cavity is integrally formed at its bottom. The lead screw 41 and the second sliding part (such as the guide rail 31 or the slide rail) can extend along the axial direction of the protective cavity. When set, the lead screw 41 and the second sliding part (guide rail 31 or slide rail) extend along the axial direction of the protective cavity and their length is less than that of the slide 10. In this way, when the slide 10 is in any position, the lead screw 41 and the second sliding part are completely surrounded by the protective cavity formed by the slide 10. When the slide 10 moves to one extreme position, the front end of the protective cavity covers the front end of the lead screw 41 and the guide rail 31; when it moves to the other extreme position, the rear end of the protective cavity covers the remaining part, blocking external impurities in all directions.

[0039] Of course, a cover can also be installed on the slide 10. During assembly, the shape of the slide 10 matches the shape of the cover. A slide groove is set on the slide 10, and the cover is inserted into the slide groove and slides with the inner wall of the slide groove, so that the cover forms a protective cavity on the slide 10. In this way, when the slide 10 reciprocates, the position of the cover remains unchanged and always covers the sliding mechanism and the transmission mechanism 40, which can also protect the structure inside the protective cavity.

[0040] Furthermore, in this embodiment, a protective cover 20 is also provided, with one end of the protective cover 20 inserted into the slide 10 and the other end of the protective cover 20 extending along the movement direction of the slide 10. A protective cavity is formed inside the protective cover 20, and the slide 10 slides and engages with the outer periphery of the protective cover 20 during movement.

[0041] Specifically, during assembly, a sliding groove or a through groove can be provided on the slide 10 to pass through the protective cover 20, so that the protective cover 20 and the slide 10 work relatively independently but in coordination. When the slide 10 reciprocates, the cover does not move with the slide 10 and its position is fixed, so that the protection of the sliding mechanism and the transmission mechanism 40 is not disturbed by the movement of the slide 10 and always maintains a stable protective state.

[0042] More specifically, since the protective cover 20 extends along the movement direction of the slide 10, it can fully cover the area through which the slide 10 moves, including the transmission mechanism 40 and the sliding mechanism. Thus, no matter where the slide 10 is on the movement trajectory, these key components can be protected by the protective cover 20, reducing the intrusion of impurities such as dust, debris, and cutting fluid, and reducing the probability of failure.

[0043] Furthermore, the protective cover 20 includes a connecting plate 21 and two baffles 22. The connecting plate 21 is connected between the two baffles 22 and partially encloses the two baffles 22 to form a protective cavity. The slide 10 is provided with a connecting groove, which includes a first groove section 11 and two second groove sections 12. The two second groove sections 12 are located on both sides of the slide 10 and are used to pass through the two baffles 22. When the two baffles 22 are subjected to force, they extend into the second groove section 12 and are used to slide and cooperate with the inner wall of the second groove section 12 when the slide 10 moves. The first groove section 11 is connected to the two second groove sections 12 respectively. The connecting plate 21 is used to be located in the first groove section 11 when the baffles 22 extend into the second groove section 12.

[0044] Specifically, during assembly, simply insert the two baffles 22 into the second slots 12 on both sides of the slide block 10, and then position the connecting plate 21 within the first slot 11 to complete the installation of the protective cover 20. During disassembly, simply pull the baffles 22 out of the second slot 12 to easily remove the protective cover 20. In this way, the protective cover 20 can be quickly removed during equipment maintenance, repair, or replacement of parts, improving the efficiency of equipment maintenance.

[0045] In addition, when the two baffles 22 extend into the second groove section 12, the connecting plate 21 is also located in the first groove section 11. The connecting plate 21 and the two baffles 22 are limited by the groove walls of the first groove section 11 and the second groove section 12, so that a tight and stable connection is formed between the protective cover 20 and the slide 10. This can effectively withstand various forces generated when the slide 10 moves, including friction and impact, so that the protective cover 20 will not easily shake or fall off during equipment operation, thereby improving the stability of the entire structure.

[0046] More specifically, the slide 10 has grip notches 13 on both sides, which are connected to the connecting groove. When installing or removing the protective cover 20, the operator can put their fingers into the grip notches 13 to easily grasp and apply force to the slide 10, thereby making it easier to insert the baffle 22 of the protective cover 20 into or pull it out of the connecting groove, thus improving the convenience of operation.

[0047] Furthermore, the protective cover 20 also includes a cover plate 23, which is detachably connected to the connecting plate 21 after the protective cover 20 extends into the connecting groove, so as to cover one end of the protective cover 20 near the slide 10.

[0048] Based on this structure, the end of the protective cover 20 near the slide 10 is sealed by the cover plate 23, which can form a more enclosed space, further preventing dust, debris and other impurities from entering the protective cavity from the connection between the protective cover 20 and the slide 10, thereby improving the overall protective performance.

[0049] In addition, since the cover plate 23 is detachable, when it is necessary to maintain, repair or replace the components inside the protective cavity, the cover plate 23 can be easily removed to open the protective cavity, which facilitates later maintenance.

[0050] More specifically, the cover plate 23 in this embodiment can also serve as a limit. When the slide 10 slides close to the cover plate 23, the cover plate 23 will block the slide 10 when it moves close to the cover plate 23, preventing it from moving further and thus avoiding it from falling off the protective cover 20. It can also prompt the user to slide to the limit position so as to adjust the movement trajectory of the slide 10 in real time.

[0051] It should be noted that in this embodiment, the cover plate 23 can be connected to the connecting plate 21 by means of threaded connection or snap-fit ​​connection.

[0052] Furthermore, the slide block 10 is also provided with a number of reinforcing ribs 14, which are distributed at intervals on the top wall of the first groove section 11.

[0053] Specifically, since the slide block 10 needs to drive the workpiece to move during the movement process, the presence of the internal connecting groove will weaken the sliding strength. Therefore, in this embodiment, multiple reinforcing ribs 14 are set and distributed at intervals on the top wall of the first groove section 11, so that when the slide block 10 is subjected to force, the pressure it bears can be evenly distributed through the multiple spaced reinforcing ribs 14, avoiding excessive force in local areas, thereby improving the load-bearing capacity, reducing the probability of it breaking due to excessive load, and indirectly extending its service life.

[0054] It should be noted that the reinforcing ribs 14 can be connected to the slide block 10 by means of integral molding or welding.

[0055] Furthermore, the protective cover 20 includes at least two support arms 24, each support arm 24 including a first plate segment 241 and a second plate segment 242. The first plate segment is connected to the bottom of the connecting plate 21, the second plate segment 242 is perpendicular to the first plate segment 241 and is connected to the first plate segment 241, and the second plate segment 242 is connected to the external structure.

[0056] Specifically, during assembly, the first plate segment 241 is set vertically and connected to the connecting plate 21, while the second plate segment 242 is perpendicular to the first plate segment 241 and is used to connect to the external structure. The vertical first plate segment 241 provides strong support rigidity in the vertical direction, preventing the protective cover 20 from sinking or deforming excessively under gravity. At the same time, the vertical second plate segment 242 increases the bending and torsional rigidity of the structure in the horizontal direction, enabling the protective cover 20 to better resist external forces from the side or other directions, improving the overall structure's resistance to different types of external forces, and thus making the connection between the protective cover 20 and the external structure more stable and reliable.

[0057] It should be noted that mounting holes or threaded holes can be provided on the second plate segment 242 for connecting to external structures (such as a base or worktable used for assembling with a sliding transmission component).

[0058] Furthermore, in this embodiment, the first sliding part is a slider 30 located at the bottom of the slide block 10, and the second sliding part is a guide rail 31 located in the protective cavity, with the slider 30 and the guide rail 31 slidingly engaged.

[0059] During specific assembly, the slider 30 can be located at the bottom of the slide block 10, while the slide rail is located inside the protective cavity and is correspondingly set and slidably engaged with the slider 30. When the entire sliding assembly is assembled with external equipment (wood saw blade or slicing device or other automated production device), the guide rail 31 can be installed on the machine base or workbench.

[0060] It should be noted that in this embodiment, there are two guide rails 31, which are respectively located on both sides of the lead screw 41. There are at least two pairs of sliders 30, which slide in cooperation with the two guide rails 31 to guide the slide block 10 to move along a predetermined motion trajectory.

[0061] Example 2,

[0062] A wood sawing device includes a base, a drive unit, and a slide transmission assembly as described in Embodiment 1. The slide 10 is used to hold the workpiece and to transport the workpiece along a conveying direction when the lead screw 41 rotates. The drive unit is used to drive the lead screw 41 to rotate.

[0063] Specifically, when the sliding transmission assembly in Embodiment 1 is applied to this embodiment, during assembly, the lead screw 41 can be extended and mounted on the machine base along the direction in which the workpiece needs to be conveyed, and connected to the drive component, so that the lead screw 41 can be driven to rotate by the drive component. When the lead screw 41 rotates, the lead screw nut 42 reciprocates along the axial direction of the lead screw 41. Since the lead screw nut 42 is connected to the slide 10, the slide 10 can also reciprocate along the axial direction of the lead screw 41. When the slide 10 moves along the axial direction (i.e., the conveying direction) of the lead screw 41, the workpiece on the slide 10 can be conveyed to the processing station for processing. After processing is completed, it returns, realizing the feeding and returning motion of the workpiece.

[0064] Meanwhile, as the first sliding part and the second sliding part slide together when the slide block 10 moves, the slide block 10 moves more smoothly in the axial reciprocating motion along the lead screw 41. Under the guidance of the second sliding part, the lead screw 41 can move in a predetermined direction, making its motion trajectory stable, avoiding deviation of the slide block 10 during the movement, and improving the stability of the movement of the slide block 10.

[0065] In addition, since the sliding mechanism and the transmission mechanism 40 are both located inside the protective cavity, the cavity wall of the protective cavity can provide overall protection for the sliding mechanism or the transmission mechanism 40 during operation. This can effectively prevent sawdust or impurities from entering the protective cavity during equipment processing, and reduce the risk of the sliding mechanism or the transmission mechanism 40 getting stuck during operation.

[0066] Compared to the traditional method, which requires installing multiple independent protective covers 20 for each part of the transmission mechanism 40 and the sliding mechanism, and each protective cover 20 needs to be individually positioned and fixed, aligned with each component of the transmission mechanism 40 and the sliding mechanism to ensure adequate protection, this method only requires repeatedly adjusting the position, which is cumbersome and time-consuming. In this implementation, the protective cavity is aligned with the area where the transmission and sliding mechanisms are located, and the positioning is completed in one go, avoiding the complicated operation of positioning multiple protective covers 20 separately. The installation process is convenient, time-saving and labor-saving.

[0067] Furthermore, the machine base is also provided with at least two guide seats 50, which are spaced apart and located in the protective cavity. The two guide seats 50 are provided with through holes 51, and the two ends of the lead screw 41 are respectively inserted into the two through holes 51.

[0068] Specifically, during installation, the two guide seats 50 are connected to the machine base and placed inside the protective cavity. The through holes 51 on the two guide seats 50 provide support points for the lead screw 41. By passing the lead screw 41 through the through holes 51, it is placed in the correct working position, providing a stable foundation for the rotation and transmission of the lead screw 41.

[0069] In addition, since the two guide seats 50 are spaced apart, the radial displacement and oscillation of the lead screw 41 during the movement can be limited, ensuring that the lead screw 41 always rotates along the predetermined axial direction, maintaining good straightness and coaxiality, which helps to improve the stability of the entire transmission system.

[0070] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
