Description

Technical Field

[0001] The present application belongs to the field of transmission technology, and more specifically, to a transmission mechanism and processing equipment. Background Art

[0002] The transmission chain will generally be stretched after being used for a period of time, resulting in a loose fit between the chain and the corresponding gears, causing the chain transmission to have poor operating stability.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] See also Figure 1, the transmission mechanism 10 provided in the embodiment of the present application is now described. The transmission mechanism 10 provided in the embodiment of the present application includes a frame 102, two transmission chains 103 and a tensioning assembly 101. The two transmission chains 103 are arranged in parallel and can be transmitted on the frame 102; the tensioning assembly 101 includes a mounting frame 1011, a rotatable first tensioning gear 1012 and a rotatable second tensioning gear 1013. The mounting frame 1011 is arranged on the frame 102, the first tensioning gear 1012 is engaged with one transmission chain 103, the first tensioning gear 1012 is movably arranged on the mounting frame 1011, and tensions the transmission chain 103; the second tensioning gear 1013 is engaged with another transmission chain 103, the second tensioning gear 1013 is movably arranged on the mounting frame 1011, and tensions the transmission chain 103; the first tensioning gear 1012 and the second tensioning gear 1013 are respectively and independently movably arranged.

[0029] In the transmission mechanism 10 of the embodiment of the present application, when the first tensioning gear 1012 is controlled to move, the transmission chain 103 can be tensioned and adjusted. Specifically, the first tensioning gear 1012 is taken as a circle, and the moving direction of the first tensioning gear 1012 is taken as moving along a corresponding radial direction. Similarly, the second tensioning gear 1013 is also taken as being movable along a corresponding radial direction. When the second tensioning gear 1013 is controlled to move along a corresponding radial direction, the transmission chain 103 can be tensioned and adjusted. The first tensioning gear 1012 and the second tensioning gear 1013 can move independently, so that the tension of the two transmission chains 103 can be adjusted independently, so that the tension of the two transmission chains 103 is consistent, and the transmission effect of the two transmission chains 103 is stable.

[0030] Among them, the frame 102 serves as a structural setting carrier of the two transmission chains 103 and the tensioning assembly 101, which helps to provide a stable structural foundation; the two transmission chains 103 are arranged in parallel for transmission of workpieces; the mounting frame 1011 in the tensioning assembly 101 serves as an intermediate piece for connecting the first tensioning gear 1012 and the second tensioning gear 1013 to the frame 102 respectively, which helps to avoid the difficulty of directly connecting the first tensioning gear 1012 and the second tensioning gear 1013 to the frame 102, and is more convenient for the matching setting between the corresponding structures; The first tensioning gear 1012 and the second tensioning gear 1013 are rotatably arranged and meshed with the corresponding transmission chain 103, and can rotate along with the transmission of the corresponding transmission chain 103, thereby playing the effect of transmitting the transmission chain 103. At the same time, by controlling the first tensioning gear 1012 and the second tensioning gear 1013 to move along the corresponding radial direction respectively, a tensioning force is applied to the corresponding transmission chain 103. The tensioning force can be a thrust effect or a pulling effect, thereby achieving the effect of adjusting the tension of the corresponding transmission chain 103.

[0031] See also Figure 2 In which, the tensioning assembly 101 of the above embodiment may also include a first adjusting member 1014, which is respectively connected to the mounting frame 1011 and the first tensioning gear 1012, and the movable direction of the first tensioning gear 1012 is defined as the first direction, denoted as X, and the first adjusting member 1014 is movable and adjustable along the first direction to control the movement of the first tensioning gear 1012.

[0032] By controlling the first adjusting member 1014 to move in the first direction, the first tensioning gear 1012 is adjusted to move relative to the mounting frame 1011 in the first direction, so as to adjust the tension of the corresponding transmission chain 103. The first adjusting member 1014 can be a driving member, that is, a setting that uses a driving member to drive the first tensioning gear 1012 to move in the first direction; the first adjusting member 1014 can also be a screw, that is, the end of the screw pushes against the first tensioning gear 1012 and is threadedly connected to the mounting frame 1011, and the first tensioning gear 1012 is adjusted to move in the first direction by turning the screw to push and adjust the first tensioning gear 1012 to move in the first direction, so as to adjust the tension of the corresponding transmission chain 103. Of course, the first adjusting member 1014 can also be any setting that satisfies the adjustment of the first tensioning gear 1012 to move relative to the mounting frame 1011 in the first direction.

[0033] Further, the first adjusting member 1014 of the above embodiment may include a first connecting portion 10141, which is movably arranged on the mounting frame 1011 along the first direction, and the first tensioning gear 1012 is rotatably arranged on the first connecting portion 10141; the first adjusting member 1014 may also include a first driving portion 10142, which is arranged on the mounting frame 1011 and is drivingly connected to the first connecting portion 10141 to drive the first connecting portion 10141 to move along the first direction.

[0034] The first connecting part 10141 is an intermediate part connecting the mounting frame 1011 and the first tensioning gear 1012, and any shape structure that meets the conditions can be used. By controlling the first driving part 10142 to drive the first connecting part 10141 to move relative to the mounting frame 1011 along the first direction, the first tensioning gear 1012 is adjusted to move along the first direction, thereby achieving the effect of adjusting the tension of the corresponding transmission chain 103. The first driving part 10142 can be an automatic driving device such as a cylinder or a driving motor, or a manual driving device, whichever meets the driving conditions.

[0035] Specifically, in the embodiment of the present application, the first driving part 10142 adopts a cylinder as an example, and the cylinder is driven along the first direction, wherein the main body of the cylinder can be arranged on the mounting frame 1011, and the driving end is drivingly connected to the first connecting part 10141; or the main body of the cylinder is arranged on the first connecting part 10141, and the driving end is drivingly connected to the mounting frame 1011. The driving air pressure of the cylinder can be controlled to be stable, so as to provide a stable driving force for the first tensioning gear 1012, thereby providing a stable and controllable tensioning force for the corresponding transmission chain 103. In this way, the corresponding transmission chain 103 can always be in the required stable tensioning degree during use.

[0036] In the embodiment of the present application, the first connecting part 10141 is taken as an example of being slidably connected with the mounting frame 1011 along the first direction, wherein the first slide rail 10111 can be set on the mounting frame 1011, and the first slider 101411 that slidably cooperates with the first slide rail 10111 can be set on the first connecting part 10141, or the first slide rail 10111 can be set on the first connecting part 10141, and the first slider 101411 that slidably cooperates with the first slide rail 10111 can be set on the mounting frame 1011. The more precise cooperation between the first slide rail 10111 and the first slider 101411 can play a structural constraint role between the first connecting part 10141 and the mounting frame 1011, which helps to ensure stable sliding cooperation between the first connecting part 10141 and the mounting frame 1011.

[0037] See also Figure 2 It can be understood that the tensioning assembly 101 of the above embodiment may also include a second adjusting member 1016, and the second adjusting member 1016 may include a second connecting portion 10161, defining the movable direction of the second tensioning gear 1013 as the first direction, and the mounting frame 1011 is provided with a second slide rail 10112 along the first direction, and the second connecting portion 10161 is provided with a second slider 101611 that slides with the second slide rail 10112, and the second tensioning gear 1013 can be rotatably arranged on the second connecting portion 10161; the second adjusting member 1016 may also include a second driving portion 10162, and the second driving portion 10162 is arranged on the mounting frame 1011, and is drivingly connected to the second connecting portion 10161 to drive the second connecting portion 10161 to slide on the second slide rail 10112 along the first direction.

[0038] The embodiment of the present application takes the adjustment setting of the second tensioning gear 1013 being equivalent to the adjustment setting of the first tensioning gear 1012 as an example. Therefore, the adjustment setting of the second adjusting member 1016 for the second tensioning gear 1013 can refer to the adjustment setting of the first adjusting member 1014 for the first tensioning gear 1012, and the setting between the second tensioning gear 1013 and the mounting bracket 1011 can refer to the setting between the first tensioning gear 1012 and the mounting bracket 1011, which will not be repeated here.

[0039] It should be noted that the moving directions of the second tensioning gear 1013 and the first tensioning gear 1012 can be the same or different, as long as the tensioning requirements of the corresponding transmission chain 103 can be met.

[0040] See also Figure 1 Furthermore, the transmission mechanism 10 in the above embodiment may also include a carrier 104, which is arranged between the two transmission chains 103, the carrier 104 is relatively fixedly connected to one transmission chain 103, and the carrier 104 is relatively movably connected to the other transmission chain 103 along the corresponding transmission direction.

[0041] After the carrier 104 is connected to the two transmission chains 103, it is used to carry the workpiece. The carrier 104 can be provided with positioning structures such as positioning grooves to position the corresponding workpiece to be transmitted. Multiple carriers 104 can be provided along the transmission direction of the transmission chain 103. Each carrier 104 is provided for example to correspond to a section of the chain, so as not to hinder the angle change of different sections of the chain. The carrier 104 is relatively fixedly connected to one transmission chain 103, and the carrier 104 is relatively movably connected or not connected to the other transmission chain 103 along the corresponding transmission direction and is in a free state. When the tensioning and stretching lengths of the two transmission chains 103 are different, the carrier 104 provided in this way can avoid angular deviation due to the different stretching lengths of the two transmission chains 103, which is helpful for positioning the workpiece in the automatic operation.

[0042] See also Figure 3 In one embodiment, the moving direction of the second tensioning gear 1013 is the same as the moving direction of the first tensioning gear 1012. The tensioning assembly 101 may further include a connecting member 1015, which can be detachably connected to the first tensioning gear 1012 and the second tensioning gear 1013 so that the first tensioning gear 1012 and the second tensioning gear 1013 can move synchronously.

[0043] In the present embodiment, the connecting member 1015 is used to detachably connect the first tensioning gear 1012 and the second tensioning gear 1013. It can be understood that the connecting member 1015 can be installed as needed. When the first tensioning gear 1012 and the second tensioning gear 1013 are connected by the connecting member 1015, the first tensioning gear 1012 and the second tensioning gear 1013 can be synchronously moved and controlled. At this time, the corresponding setting for synchronously controlling the movement of the first tensioning gear 1012 and the second tensioning gear 1013 can be used. For example, one cylinder is used to control the synchronous movement of the first tensioning gear 1012 and the second tensioning gear 1013. Of course, two cylinders can also be used to synchronously control the synchronous movement of the first tensioning gear 1012 and the second tensioning gear 1013.

[0044] When the connecting member 1015 is removed, the first tensioning gear 1012 and the second tensioning gear 1013 can still be controlled separately, and the specific separate control can refer to the above embodiment of the present application. It can be understood that the present embodiment can realize the synchronous control mode and the independent control mode of the first tensioning gear 1012 and the second tensioning gear 1013 through the scheme that the connecting member 1015 can be detachably connected to the first tensioning gear 1012 and the second tensioning gear 1013, so as to meet more usage requirements.

[0045] Among them, when the connecting member 1015 in the above embodiment is connected to the first tensioning gear 1012 and the second tensioning gear 1013, the carrier 104 of the transmission mechanism 10 is relatively fixedly connected to the two transmission chains 103 respectively, and the carrier 104 and the two transmission chains 103 are relatively fixedly connected. Taking the detachable connection method as an example, it can be understood that when the connecting member 1015 is connected to the first tensioning gear 1012 and the second tensioning gear 1013, the corresponding two transmission chains 103 are tensioned and stretched to the same extent, and the carrier 104 and the two transmission chains 103 are relatively fixedly connected. It can not only always be in a state of unchanged angle, but also play a role in supporting and fixing the two transmission chains 103 relatively.

[0046] See also Figure 1 Further, in any of the above embodiments, the two transmission chains 103 are connected end to end for a cyclic transmission arrangement, and the first tensioning gear 1012 and the second tensioning gear 1013 are arranged in the frame 102 and respectively engage with the outer side of the closed loop of the corresponding transmission chain 103.

[0047] In the embodiment of the present application, each transmission chain 103 is a closed-loop structure connected end to end, and the transmission chain 103 can be cyclically transmitted during operation. In the embodiment of the present application, the first tensioning gear 1012 and the second tensioning gear 1013 are arranged in the frame 102, and respectively engage with the outer side of the corresponding closed loop of the transmission chain 103 as an example, and the movement direction of the first tensioning gear 1012 and the second tensioning gear 1013 is close to the inner side of the frame 102, so that the movement of the first tensioning gear 1012 and the second tensioning gear 1013 are completed in the frame 102 structure, which can help optimize the structural space.

[0048] See also Figure 4 The embodiment of the present application also provides a processing equipment 20, including a baking mechanism 201 and the transmission mechanism 10 in any of the above embodiments, and two transmission chains 103 can be moved through the baking area of ​​the baking mechanism 201 to transport the workpiece into the baking area of ​​the baking mechanism 201, so that the baking mechanism 201 can perform heat treatment on the workpiece.

[0049] Since the processing equipment 20 of the embodiment of the present application includes the transmission mechanism 10 in any of the above embodiments, it has the beneficial effects brought by the transmission mechanism 10 in any of the above embodiments, which will not be described in detail here.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
