[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] It should be understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] See also Figures 1 to 3 as well as Figure 5 The embodiment of the utility model provides an engagement adjustment device 100, including a guide rail 13, a rack 15, a supporting assembly 20, a driving member 30, a mounting member 40 and an elastic member 50. The guide rail 13 and the rack 15 are arranged in parallel. The supporting assembly 20 is slidably arranged on the guide rail 13. A gear 31 is provided at the output end of the driving member 30, and the gear 31 is engaged with the rack 15. The mounting member 40 is rotationally connected to the supporting assembly 20 along the axial direction of the gear 31, and the driving member 30 is arranged on the mounting member 40. One end of the elastic member 50 is connected to the supporting assembly 20, and the other end of the elastic member 50 is connected to the mounting member 40, so as to provide elastic force for the gear 31 to engage with the rack 15.

[0044] In the embodiment of the utility model, during the rotation of the gear 31 relative to the rack 15, when the meshing clearance between the gear 31 and the rack 15 is large, the elastic force of the elastic member 50 can drive the mounting member 40 to rotate relative to the supporting assembly 20, so that the position of the gear 31 arranged on the mounting member 40 rotates relative to the supporting assembly 20. Since the supporting assembly 20 is arranged on the guide rail 13 arranged parallel to the rack 15, the meshing clearance between the gear 31 and the rack 15 can be reduced. When the meshing clearance between the gear 31 and the rack 15 is large, the force applied by the rack 15 to the gear 31 overcomes the elastic force applied by the elastic member 50 to the gear 31, and the mounting member 40 rotates relative to the supporting assembly 20 to increase the meshing clearance between the gear 31 and the rack 15, thereby avoiding the meshing clearance between the gear 31 and the rack 15 being too large or too small, thereby ensuring a good meshing relationship between the gear 31 and the rack 15.

[0045] Specifically, since the rack 15 may have installation errors during the installation process and the rack 15 may have production errors during the production process, both of which may cause the rack 15 to have slight bending, making it impossible for the gear 31 to maintain a suitable meshing gap with the rack 15 everywhere. Therefore, in the present application, an elastic member 50 is provided to elastically adjust the meshing gap between the gear 31 and the rack 15, which can well adapt to installation errors and production errors and ensure a good meshing relationship between the gear 31 and the rack 15.

[0046] The meshing adjustment device may also include structures such as a machine bed 11, a crossbeam, and a conveyor belt, and the present application does not impose specific restrictions. The guide rail 13 and the rack 15 may be arranged in parallel on the machine bed 11, and the guide rail 13 is used to guide the support assembly 20 to slide relative to the machine bed 11, and the gear 31 of the driving member 30 can rotate relative to the rack 15 to drive the mounting member 40 connected to the driving member 30 to move relative to the machine bed 11, thereby driving the support assembly 20 rotatably connected to the mounting member 40 to slide relative to the machine bed 11.

[0047] It can be understood that the supporting assembly 20 can include sliding fittings such as sliders and rollers that can cooperate with the slide rails. The supporting assembly 20 can be slidably set on the guide rail 13, and this application does not make specific restrictions.

[0048] Since the supporting assembly 20 cooperates with the guide rail 13, the supporting assembly 20 can provide a general direction for the movement of the driving member 30, ensuring that the gear 31 can move along the setting direction of the rack 15; and since the supporting assembly 20 is rotatably connected to the mounting member 40, the driving member 30 can achieve delicate fine-tuning of the movement direction of the driving member 30 when the mounting member 40 rotates relative to the supporting assembly 20, ensuring that the gear 31 can move in line with the rack 15 and maintain a suitable meshing gap between the gear 31 and the rack 15.

[0049] The driving member 30 may include a driving device such as a reducer, a rotary cylinder, etc., which is not specifically limited in the present application. The driving member 30 is used to drive the supporting assembly 20 to slide.

[0050] The mounting member 40 is used to carry the driving member 30, and the mounting member 40 can be rotated relative to the supporting assembly 20 to finely adjust the relative position relationship between the driving member 30 and the rack 15, providing a basis for adjusting the meshing clearance between the gear 31 and the rack 15. It can be understood that the mounting member 40 is rotatably connected with the supporting assembly 20, and during the meshing process of the gear 31 and the rack 15, the force of the rack 15 on the gear 31 is transmitted to the mounting member 40 through the driving member 30, and the elastic member 50 abuts against the mounting member 40 to provide elastic force for the mounting member 40, that is, the supporting assembly 20, the rack 15 and the elastic member 50 act on the mounting member 40 together to maintain the relative position relationship between the mounting member 40 and the supporting assembly 20. When the force of the rack 15 on the gear 31 increases or decreases, the mounting member 40 moves relative to the supporting assembly 20, so that the elastic force of the elastic member 50 changes accordingly, so that the force on the mounting member 40 reaches a new balance, so that the relative position relationship between the mounting member 40 and the supporting assembly 20 is stabilized again.

[0051] The elastic member 50 may include a tension spring, a compression spring, a torsion spring, etc.

[0052] It is worth noting that the elastic force provided by the elastic member 50 to the mounting member 40 should have at least a component force in the opposite direction to the force provided indirectly by the rack 15 to the mounting member 40. Since the force of the rack 15 on the gear 31 is a reaction force, the elastic force indirectly applied by the elastic member 50 to the gear 31 should be able to drive the gear 31 close to the rack 15. It can be understood that at least there is a component force in the opposite direction, which can be that the elastic force provided by the elastic member 50 to the mounting member 40 is opposite to the force provided by the rack 15 to the mounting member 40, or that a part of the component force of the elastic force provided by the elastic member 50 to the mounting member 40 is opposite to the force provided by the rack 15 to the mounting member 40, and the present application does not make specific restrictions.

[0053] It is understandable that there are many ways to set the elastic member 50. In a certain embodiment, the driving member 30 and the elastic member 50 are respectively arranged on two opposite sides of the rotational connection between the mounting member 40 and the supporting assembly 20, and the elastic member 50 is a tension spring; in another embodiment, the driving member 30 and the elastic member 50 are arranged on one side of the rotational connection between the mounting member 40 and the supporting assembly 20, and the elastic member 50 is a compression spring; in another embodiment, the elastic member 50 is a torsion spring, and the elastic member 50 is arranged at the rotational connection between the mounting member 40 and the supporting assembly 20. There are many other ways to set the elastic member 50, which are not listed one by one in this application.

[0054] See also Figure 2 , Figure 3 and Figure 5 In the embodiment of the utility model, the supporting assembly 20 includes a supporting member 21, a fixing block 22, an adjusting screw 23 and a contact member 24. The supporting member 21 is slidably connected to the guide rail 13, the fixing block 22 is arranged on the supporting member 21, the adjusting screw 23 is threadedly connected to the fixing block 22, the contact member 24 is arranged on the adjusting screw 23, the elastic member 50 is sleeved on the adjusting screw 23, and one end of the elastic member 50 is in contact with the contact member 24.

[0055] In this way, the supporting component 20 abuts against the elastic component 50 through the abutment member 24 provided on the adjusting screw 23, and the other end of the elastic component 50 is connected to the mounting member 40, so that the supporting component 20 is indirectly connected to the mounting member 40 through the adjusting screw 23, and the relative position relationship between the adjusting screw 23 and the fixing block 22 can be adjusted by turning the adjusting screw 23, thereby adjusting the relative position relationship between the supporting component 21 and the mounting member 40, thereby achieving fine adjustment of the initial position of the gear 31, ensuring that the initial position of the gear 31 has a good matching relationship with the rack 15, reducing the requirements for production errors and installation errors, and achieving better transmission effects at a lower cost; in addition, since the elastic component 50 is sleeved on the adjusting screw 23, the adjusting screw 23 can also play a certain supporting role on the elastic component 50, reduce the probability of bending of the elastic component 50, and ensure that the elastic component 50 can continue to provide good elastic force.

[0056] It can be understood that before the engagement adjustment device 100 is used, the initial position of the gear 31 and the rack 15 can be adjusted by screwing the adjustment screw 23, so that the gear 31 and the rack 15 are generally in a better meshing state; during the use of the engagement adjustment device 100, since the rack 15 may be offset during the installation of the rack 15, or the rack 15 may have uneven parts during the production process, the elastic member 50 is required to compensate for the problem of excessive or small meshing clearance between the gear 31 and the rack 15 during use, so as to ensure that the gear 31 and the rack 15 are in a better meshing state.

[0057] It is understandable that there are many ways to threadably connect the adjusting screw 23 to the fixed block 22. The fixed block 22 may also include a nut, and the adjusting screw 23 is threadably connected to the nut; or a threaded hole may be provided in the fixed block 22, and the adjusting screw 23 is threadably connected to the threaded hole. This application does not impose any specific restrictions.

[0058] See also Figure 2 and Figure 5 Furthermore, the mounting member 40 is provided with a matching through hole (not shown), the adjusting screw 23 passes through the matching through hole, the mounting member 40 and the adjusting screw 23 are clearance-matched, and one end of the elastic member 50 is connected to the mounting member 40 .

[0059] In this way, when the mounting member 40 rotates relative to the supporting member 21, since the adjusting screw 23 is passed through the matching through hole, the adjusting screw 23 can play a certain guiding role in the rotation of the mounting member 40, reduce the limiting pressure at the rotating connection between the mounting member 40 and the supporting member 21, and increase the service life of the mounting member 40 and the supporting member 21 to a certain extent.

[0060] It can be understood that the clearance fit between the mounting member 40 and the adjusting screw 23 means that the size of the fitting through hole is larger than the size of the adjusting screw 23 , so that the mounting member 40 can move relative to the adjusting screw 23 .

[0061] For further information, see Figure 2 and Figure 5 The matching position of the mounting member 40 and the adjusting screw 23 is located between the threaded connection between the adjusting screw 23 and the fixing block 22 and the connection between the adjusting screw 23 and the abutting member 24 .

[0062] In this way, a fixing block 22 and an abutment 24 are respectively provided at both ends of the axial direction of the mating through hole. The fixing block 22 and the abutment 24 can limit the mounting member 40 to prevent the adjusting screw 23 from detaching from the mating through hole. In addition, the mounting member 40 can also limit the elastic member 50 together with the abutment 24. The two ends of the elastic member 50 can be respectively abutted against the mounting member 40 and the abutment 24, which is convenient for installation.

[0063] It is understandable that in other embodiments, the elastic member 50 is fixedly connected to the mounting member 40 to limit the mounting member 40 and prevent the mounting member 40 from being separated from the adjusting screw 23. Since the fixing block 22 and the abutment member 24 jointly limit the mounting member 40, there is no need for the elastic member 50 to limit the mounting member 40 to prevent the mounting member 40 from being separated from the adjusting screw 23. The elastic member 50 can be abutted against the mounting member 40, and the elastic member 50 can be easily installed or replaced, which is convenient for installation and reduces costs.

[0064] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 In the embodiment of the utility model, the supporting component 20 is provided with a threaded hole (not shown) along the axial direction of the gear 31, the meshing adjustment device 100 also includes a screw with a grinding pad 61 and a locking screw 63, the mounting member 40 is provided with a waist-shaped hole 41, and the length direction of the waist-shaped hole 41 is an arc with the rotation connection between the supporting component 20 and the mounting member 40 as the center, and the locking screw 63 is sequentially penetrated by the screw with a grinding pad 61 and the waist-shaped hole 41, and is threadedly connected with the threaded hole.

[0065] In this way, the locking screw 63 can limit the supporting assembly 20 and the mounting member 40 along the axial direction of the gear 31, thereby ensuring the stability of the relative position relationship between the supporting assembly 20 and the mounting member 40 in the axial direction of the gear 31, and maintaining a good meshing relationship between the gear 31 and the rack 15 in the axial direction; in addition, when the mounting member 40 rotates relative to the supporting assembly 20, the locking screw 63 can move in the waist-shaped hole 41, that is, the waist-shaped hole 41 can play a certain guiding role on the locking screw 63, thereby guiding the mounting member 40 to rotate relative to the supporting assembly 20, reducing the limiting pressure at the rotating connection between the mounting member 40 and the supporting assembly 20, and improving the service life of the mounting member 40 and the supporting assembly 20.

[0066] It is understandable that, under normal circumstances, the rack 15 and the gear 31 are helical meshing, and when the gear 31 rotates relative to the rack 15, a component force is generated along the axial direction of the gear 31. By setting the locking screw 63, the mounting member 40 and the supporting assembly 20 are locked, thereby ensuring the stability of the relative position relationship between the mounting member 40 and the supporting assembly 20 in the axial direction of the gear 31, and ensuring that the gear 31 and the rack 15 have a good meshing relationship.

[0067] It can be understood that when the mounting member 40 rotates relative to the supporting assembly 20 , the locking screw 63 can slide on the screw-matching grinding pad 61 .

[0068] It can be understood that the mounting member 40 can be provided with 1, 2, 3, 4 or other number of waist-shaped holes 41. The number of waist-shaped holes 41 can be adjusted according to factors such as the size of the waist-shaped holes 41 and the magnitude of the component force along the axial direction of the gear 31. This application does not impose any specific restrictions.

[0069] For further information, see Figure 6 The locking screw 63 includes a screw head 631, an optical axis section 633 and a threaded section 635. The optical axis section 633 connects the screw head 631 and the threaded section 635. The screw head 631 abuts against the screw grinding pad 61. The optical axis section 633 penetrates the screw grinding pad 61 and the waist-shaped hole 41. The threaded section 635 is threadedly connected to the threaded hole.

[0070] In this way, the threaded section 635 can be threadedly connected with the threaded hole, the optical axis can slide in the waist-shaped hole 41, and the screw head 631 can abut against the screw grinding pad 61, so as to achieve a good matching relationship between the locking screw 63 and the supporting component 20 and the mounting part 40.

[0071] See also Figure 7 In the embodiment of the utility model, the supporting assembly 20 further includes an oil-free bushing 25 and a rotating shaft 26 . The rotating shaft 26 is disposed in the oil-free bushing 25 , and the mounting member 40 is connected to the rotating shaft 26 .

[0072] In this way, the mounting member 40 and the supporting assembly 20 cooperate with each other through the rotating shaft 26 and the oil-free bushing 25 to achieve a rotational connection between the mounting member 40 and the supporting assembly 20 .

[0073] For further information, see Figure 7 The engagement adjustment device 100 further includes a locking nut 71 and a rotating shaft grinding pad 73 . The rotating shaft 26 is passed through the mounting member 40 . The locking nut 71 is threadedly connected to the rotating shaft 26 . The locking nut 71 abuts against the mounting member 40 through the rotating shaft grinding pad 73 .

[0074] In this way, the connection between the mounting member 40 and the rotating shaft 26 is achieved by providing the locking nut 71, which has a simple structure, is easy to install, and has a low production cost.

[0075] For further information, see Figure 7 The supporting assembly 20 also includes a limiting member 27 and a cover plate 28. The limiting member 27 is provided with an opening (not marked), and the cover plate 28 covers the opening. The cover plate 28 is detachably connected to the limiting member 27. A limiting groove 271 is provided on the side of the limiting member 27 close to the cover plate 28. The oil-free bushing 25 is provided with a first limiting protrusion 251, and the rotating shaft 26 is provided with a second limiting protrusion 261. The first limiting protrusion 251 and the second limiting protrusion 261 are accommodated in the limiting groove 271. One side of the second limiting protrusion 261 abuts against the groove wall of the limiting groove 271 through the first limiting protrusion 251, and the other side of the second limiting protrusion 261 abuts against the cover plate 28.

[0076] In this way, the oil-free bushing 25 and the rotating shaft 26 can be installed into the limiting member 27 through the opening, and then the cover plate 28 can be used to seal the opening. The rotating shaft 26 and the oil-free bushing 25 can be installed first, and then the mounting member 40 can be connected to the rotating shaft 26, so as to facilitate the rotational connection between the mounting member 40 and the supporting assembly 20, with a simple structure and easy installation.

[0077] It is understandable that there are many ways to detachably connect the cover plate 28 and the limit member 27. The cover plate 28 and the limit member 27 can be threadedly connected, or the cover plate 28 can be detachably connected to the limit member 27 via screws. This application does not make any specific restrictions.

[0078] An embodiment of the utility model also provides a processing equipment, which includes an engagement adjustment device 100. The specific structure of the engagement adjustment device 100 refers to the above embodiment. Since the processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0079] It is understandable that the processing equipment may also include a laser cutting device, a feeding device, an exhaust dust removal device, etc., and this application does not make specific restrictions.

[0080] In the processing equipment in the embodiment of the utility model, during the rotation of the gear 31 relative to the rack 15, when the meshing clearance between the gear 31 and the rack 15 is large, the elastic force of the elastic member 50 can drive the mounting member 40 to rotate relative to the supporting assembly 20, so that the position of the gear 31 arranged on the mounting member 40 rotates relative to the supporting assembly 20. Since the supporting assembly 20 is arranged on the guide rail 13 arranged parallel to the rack 15, the meshing clearance between the gear 31 and the rack 15 can be reduced. When the meshing clearance between the gear 31 and the rack 15 is large, the force applied by the rack 15 to the gear 31 overcomes the elastic force applied by the elastic member 50 to the gear 31, and the mounting member 40 rotates relative to the supporting assembly 20 to increase the meshing clearance between the gear 31 and the rack 15, thereby avoiding the meshing clearance between the gear 31 and the rack 15 being too large or too small, thereby ensuring a good meshing relationship between the gear 31 and the rack 15.

[0081] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
