Description

Technical Field

[0001] The utility model relates to the technical field of spraying swing frames, in particular to an adjustable spraying swing frame. Background Technique

[0002] In the traditional part spraying process, the parts to be sprayed need to be placed on a swing frame (placement frame), and then the worker holds a spray gun to spray around the parts respectively or rotates the swing frame to achieve comprehensive spraying of the parts. In order to adapt to parts with different tooth sizes, as Figure 1 shown, the swing frame includes a base 1, a fixing block 2 arranged on the base 1, and two shelves 3 rotatably wound around the fixing block 2. Specifically, both the front and rear sides of the fixing block 2 have laterally protruding limiting columns 21, and the above-mentioned shelves 3 are wound around the limiting columns 21. Among them, both the front side part and the rear side wall of the fixing block 2 have insertion holes 20 arranged in a circumferential order with the limiting column 21 as the center. After the two shelves 3 are adjusted to corresponding angles, their ends can be inserted into the corresponding insertion holes 20. After the two shelves 3 are inserted into different insertion holes 20, the opening or distance between the two shelves 3 is different, and parts of different sizes can be placed.

[0003] However, the above-mentioned spraying swing frame still has certain deficiencies. When adjusting this swing frame each time, it is necessary to first disengage the end of the shelf from the insertion hole and then insert it into another required insertion hole. Both shelves need to be operated in this way, and its adjustment steps and process are relatively cumbersome. On the other hand, repeatedly swinging the end of the shelf will also affect the strength and service life of the shelf.

[0004] It should be noted here that the statements and drawings in this background technical part only provide background technology related to the present application and do not necessarily constitute prior art. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an adjustable spraying swing frame that can adapt to parts of different sizes and is convenient and easy to operate in the opening adjustment process in view of the current situation of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: an adjustable spraying swing frame, including:

[0007] A base;

[0008] A connection module arranged on the base;

[0009] It further includes:

[0010] Two sets of adjusting plate assemblies are respectively arranged on the front and rear side walls of the connection module. Each set of adjusting plate assemblies includes a first adjusting plate and a second adjusting plate arranged in sequence from left to right. The first adjusting plate is rotatably arranged on the connection module around a first axis extending in the front-rear direction and has a first arc-shaped tooth centered on the position where the first axis is located. The second adjusting plate is rotatably arranged on the connection module around a second axis extending in the front-rear direction and has a second arc-shaped tooth centered on the position where the second axis is located. The first arc-shaped tooth meshes with the second arc-shaped tooth;

[0011] A first shelf and a second shelf. The first shelf is arranged between the first adjusting plates of the two sets of adjusting plate assemblies, and the second shelf is arranged between the first adjusting plates of the two sets of adjusting plate assemblies. The first shelf and the second shelf can rotate with the corresponding first adjusting plate and second adjusting plate to change the opening degree between the first shelf and the second shelf;

[0012] A locking assembly includes a locking member movably arranged on the connection module in a manner that can move back and forth relative to the connection module. With the change of its front-rear position, the locking member has a locking state in which at least one of the first adjusting plate and the second adjusting plate can be pressed to limit the rotation of the first adjusting plate and the second adjusting plate, and an unlocking state in which the pressing on the first adjusting plate and / or the second adjusting plate is released to allow the first adjusting plate and the second adjusting plate to rotate freely.

[0013] The above-mentioned base and the connection module can be an integrated part designed integrally, or two independent separate parts, that is, the connection module is installed on the base by a detachable connection or a fastening connection method.

[0014] Generally speaking, the locking member can lock only the first adjusting plate or the second adjusting plate on the front side or only the first adjusting plate or the second adjusting plate on the rear side. However, in order to ensure the reliability after the two adjusting plates are adjusted to the set positions, the locking member includes a first knob threadedly connected to the front side wall of the connection module and capable of moving back and forth for adjustment, and a second knob threadedly connected to the rear side wall of the connection module and capable of adjusting back and forth.

[0015] In order to be able to press and lock the first adjusting plate and the second adjusting plate simultaneously, considering reducing the number of parts and simplifying the operation steps, the first knob is connected to the upper region of the front side wall of the connection module at the meshing position of the first adjusting plate and the second adjusting plate. The first knob can press the first adjusting plate and the second adjusting plate simultaneously to limit the rotation of the first adjusting plate and the second adjusting plate; the second knob is connected to the upper region of the rear side wall of the connection module at the meshing position of the first adjusting plate and the second adjusting plate. The second knob can press the first adjusting plate and the second adjusting plate simultaneously to limit the rotation of the first adjusting plate and the second adjusting plate.

[0016] To avoid the problem of pinching hands when the user touches the arc-shaped teeth of the first adjusting plate and the second adjusting plate when operating the above-mentioned first knob or second knob, a protective convex portion extending outward is further provided in at least one of the front side wall and the rear side wall of the connection module in a region corresponding to and below the meshing position of the first adjusting plate and the second adjusting plate. The protective convex portion can adopt mechanisms such as a convex column or a plate body, as long as there is no interference with the adjusting plate and it can play a role of isolation and protection.

[0017] To avoid the problem of slipping during the operation of the above two knobs, anti-slip patterns are provided on the outer peripheral walls of the first knob and the second knob.

[0018] Generally speaking, the above-mentioned first adjusting plate and second adjusting plate can be circular plates or sector plates. If they are circular plates, a corresponding circle of arc-shaped teeth can be provided. If they are sector plates, a corresponding arc-shaped tooth at one end can be provided. Preferably, in consideration of simplifying the structure of the adjusting plate and adapting to the adjustment angle of the corresponding shelf, the main body of the first adjusting plate is a sector structure centered on the position where the first axis is located, and the first arc-shaped teeth are arranged on the arc of the sector structure. The main body of the second adjusting plate is a sector structure centered on the position where the second axis is located, and the second arc-shaped teeth are arranged on the arc of the sector structure.

[0019] To ensure that the two first adjusting plates or the two second adjusting plates on the front and rear sides can rotate synchronously, a rotating shaft is further included, which is arranged through the connection module in the front-rear direction and can rotate relative to the connection module. The first adjusting plates of the two adjusting plate assemblies are respectively connected to the two ends of the rotating shaft, or the second adjusting plates of the two adjusting plate assemblies are respectively connected to the two ends of the rotating shaft.

[0020] In order to install the first shelf and the second shelf to the corresponding first adjustment plate and the second adjustment plate, a first plug hole is opened on the front side surface of the first adjustment plate located on the front side, and a first limiting column protruding forward is provided at a position adjacent to the first axis; a second plug hole is opened on the rear side surface of the first adjustment plate located on the rear side, and a second limiting column protruding backward is provided at a position adjacent to the first axis; a third plug hole is opened on the front side surface of the second adjustment plate located on the front side, and a third limiting column protruding forward is provided at a position adjacent to the second axis; a fourth plug hole is opened on the rear side surface of the second adjustment plate located on the rear side, and a fourth limiting column protruding forward is provided at a position adjacent to the second axis. The first shelf is U-shaped as a whole, including a first cross bar and two first vertical bars respectively connected to the two ends of the first cross bar and arranged side by side, the middle parts of the two first vertical bars are respectively wrapped around the first limit column and the second limit column, and the ends of the two first vertical bars are respectively inserted into the first socket and the second socket, the second shelf is U-shaped as a whole, including a second cross bar and two second vertical bars respectively connected to the two ends of the second cross bar and arranged side by side, the middle parts of the two second vertical bars are respectively wrapped around the third limit column and the fourth limit column, and the ends of the two second vertical bars are respectively inserted into the third socket and the fourth socket.

[0021] As an improvement, the first and second plug holes are disposed adjacent to the first arc-shaped teeth of the corresponding first adjustment plate, and the third and fourth plug holes are disposed adjacent to the second arc-shaped teeth of the corresponding second adjustment plate.

[0022] In order to prevent the first shelf and the second shelf from falling off from the corresponding limit stop parts, the outer peripheral wall of the end of the first limit column also has a first limit stop part extending radially outward to limit the first vertical rod from falling out to the side, the outer peripheral wall of the end of the second limit column also has a second limit stop part extending radially outward to limit the first vertical rod from falling out to the side, the outer peripheral wall of the end of the third limit column also has a third limit stop part extending radially outward to limit the second vertical rod from falling out to the side, and the outer peripheral wall of the end of the fourth limit column also has a fourth limit stop part extending radially outward to limit the second vertical rod from falling out to the side. The above-mentioned first limit stop part, second limit stop part, third limit stop part and fourth limit stop part can be components designed integrally with the corresponding adjustment plate, such as flanges, or can be split parts detachably connected to the corresponding adjustment plate, such as gaskets fixed by screws.

[0023] To facilitate the rotation of the components placed on the spraying rack for full spraying, the base includes a fixed seat and a movable seat. The fixed seat includes a first disc body and a positioning shaft extending upward from the middle of the first disc body. The movable seat includes a second disc body and a connecting shaft extending upward from the middle of the second disc body. At a position corresponding to the connecting shaft on the bottom of the second disc body, there is an upward concave shaft hole for the positioning shaft to be inserted therein. The movable seat can rotate relative to the fixed seat around the positioning shaft;

[0024] The connection module is detachably connected to the top of the connecting shaft; or

[0025] It further includes a heightening joint detachably connected to the connecting shaft, and the connection module is detachably connected to the top of the heightening joint.

[0026] Compared with the prior art, the advantages of the present utility model are as follows: The first adjusting plate and the second adjusting plate arranged in sequence from left to right are meshed through corresponding arc-shaped teeth. By rotating the first adjusting plate and the second adjusting plate, the opening degree between the first shelf and the second shelf can be adjusted. After adjusting to a predetermined opening degree, it is then locked through the locking assembly, so that the first shelf and the second shelf can be maintained at this opening angle, and then parts of corresponding sizes can be placed. This adjustable spraying rack is convenient and easy to operate during the opening degree adjustment process, and can effectively improve the spraying efficiency. Description of the Drawings

[0034] The following further describes the present utility model in detail with reference to the embodiments accompanied by the drawings.

[0035] In the description and claims of the present utility model, terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present utility model. However, these terms are used here only for the purpose of convenient description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0036] Figures 2 - 7 A preferred embodiment of the adjustable spraying swing frame of the present utility model is shown. The adjustable spraying swing frame includes a base 1, a connection module 2, two groups of adjusting plate assemblies, a first shelf 70, a second shelf 80, and a locking assembly.

[0037] See Figure 6 and Figure 7 , the base 1 includes a fixed seat 11 and a movable seat 12. The fixed seat 11 includes a first disk body 111 and a positioning shaft 112 extending upward from the middle of the first disk body 111. The first disk body 111 can be a disk-shaped, square-shaped or other shaped disk body structure, mainly used to be placed on the tabletop of the workbench. The movable seat 12 includes a second disk body 121 and a connecting shaft 122 extending upward from the middle of the second disk body 121. The second disk body 121 can also be a disk-shaped, square-shaped or other shaped disk body structure, preferably having the same shape as the first disk body 111. As Figure 3 shown, both the first disk body 111 and the second disk body 121 are disk-shaped, and their radial dimensions are basically the same. The middle area at the bottom of the second disk body 121 has an upwardly recessed shaft hole 123 at a position corresponding to the connecting shaft 122. During assembly, the positioning shaft 112 on the first disk body 111 can be inserted into the shaft hole 123 of the second disk body 121. Among them, the positioning shaft 112 of the first disk body 111 is a conical structure with an outer diameter gradually decreasing from bottom to top, and the shaft hole 123 of the second disk body 121 also corresponds to a tapered hole structure with an inner diameter gradually decreasing from bottom to top. After the second disk body 121 is assembled in place, there is a slight gap between the bottom wall of the main body of the second disk body 121 and the top wall of the main body of the first disk body 111, reducing the contact area between the two and reducing the friction force, so as to ensure that the movable seat 12 can rotate flexibly relative to the fixed seat 11 around the positioning shaft 112.

[0038] To ensure that the swing frame has sufficient height, a vertically extending heightening joint assembly 13 can be additionally provided on the connecting shaft 122 of the second disk body 121, and the above-mentioned connecting module 2 is arranged at the top of the heightening joint. Specifically, the heightening joint assembly can be a single heightening joint, or can be formed by sleeving two or more heightening joints in sequence. Users can select an appropriate number of heightening joints according to the height requirements of the sprayed parts. Each heightening joint has a tapered hole at the bottom. The bottommost heightening joint can be sleeved on the top of the connecting shaft 122 and connected by a tight fit. Correspondingly, the top of the connecting shaft 122 is designed as a tapered head structure adapted to the inner hole of the above-mentioned heightening joint. The bottom of the connecting module 2 has a downwardly extending connecting sleeve 21, which can be sleeved on the top of the heightening joint 13 and connected by a tight fit. Specifically, the inner hole of the connecting sleeve 21 is also a tapered hole, and its taper is the same as that of the tapered hole at the bottom of the heightening joint. Of course, the heightening joint 13 and the connecting shaft 122, as well as the connecting module 2 and the heightening joint 13, can also be connected by a threaded connection. When the connecting shaft 122 on the second disk body 121 has sufficient length, the above-mentioned heightening joint 13 can be omitted, and the connecting module 2 can be directly installed on the connecting shaft 122.

[0039] See Figure 6 , the vertical section of the connecting module 2 cut along the left-right direction is a diamond structure. There are through holes 20 running through the front and back on both the left and right edge positions of the connecting module 2. A first rotating shaft 51 and a second rotating shaft 52 are respectively inserted into the two through holes 20. Two groups of adjusting plate assemblies are respectively arranged on the front and back side walls of the connecting module 2. Each group of adjusting plate assemblies includes a first adjusting plate 3 and a second adjusting plate 4 arranged in sequence from left to right. The first adjusting plate 3 and the second adjusting plate 4 in this embodiment are both fan-shaped structures and are symmetrically arranged in the left-right direction. The angular positions of the sectors of the front and back first adjusting plates 3 (i.e., the included angle positions of the two side edges) are connected to the two ends of the first rotating shaft 51 and can rotate synchronously with the first rotating shaft 51. The axis of the first rotating shaft 51 is the first axis. Similarly, the angular positions of the sectors of the front and back second adjusting plates 4 are connected to the two ends of the second rotating shaft 52 and rotate synchronously with the second rotating shaft 52. The axis of the second rotating shaft 52 is the second axis. The first arc-shaped teeth 30 of the first adjusting plate 3 on the front side of the connecting module 2 are engaged with the second arc-shaped teeth 40 of the second adjusting plate 4, and the first arc-shaped teeth 30 of the first adjusting plate 3 on the back side of the connecting module 2 are engaged with the second arc-shaped teeth 40 of the second adjusting plate 4.

[0040] See Figure 3 and Figure 4, a first jack 321 is formed on the front side of the first adjusting plate 3 located at the front side, and the first jack 321 is adjacent to the first arc-shaped tooth 30 of the first adjusting plate 3. On the front side of the first adjusting plate 3 located at the front side, there is also a first limiting post 311 protruding forward at a position adjacent to the first axis. On the outer peripheral wall of the end of the first limiting post 311, there is also a first limiting stop 61 extending radially outward. Specifically, the first limiting stop 61 is a first gasket connected to the end wall of the first limiting post 311 by a screw 331, and the diameter of the first gasket is larger than the outer diameter of the first limiting post 311. Among them, the first gasket and the screw 331 can also be an integral part, that is, a screw component with a gasket structure is adopted. A second jack 322 is formed on the rear side of the first adjusting plate 3 located at the rear side, and the second jack 322 is adjacent to the first arc-shaped tooth 30 of the first adjusting plate 3. On the rear side of the first adjusting plate 3 located at the rear side, there is also a second limiting post 312 protruding backward at a position adjacent to the first axis. On the outer peripheral wall of the end of the second limiting post 312, there is also a second limiting stop 62 extending radially outward. Specifically, the second limiting stop 62 is a second gasket connected to the end wall of the second limiting post 312 by a screw 332, and the diameter of the second gasket is larger than the outer diameter of the second limiting post 312. The second gasket and the screw 332 can also be an integral part, that is, a screw component with a gasket structure is adopted. A third jack 421 is formed on the front side of the second adjusting plate 4 located at the front side, and the third jack 421 is adjacent to the second arc-shaped tooth 40 of the second adjusting plate 4. On the front side of the second adjusting plate 4 located at the front side, there is also a third limiting post 411 protruding forward at a position adjacent to the second axis. On the outer peripheral wall of the end of the third limiting post 411, there is also a third limiting stop 63 extending radially outward. Specifically, the third limiting stop 63 is a third gasket connected to the end wall of the third limiting post 411 by a screw 431, and the diameter of the third gasket is larger than the outer diameter of the third limiting post 411. The third gasket and the screw 431 can also be an integral part, that is, a screw structure with a gasket structure is adopted. A fourth jack 422 is formed on the rear side of the second adjusting plate 4 located at the rear side, and the fourth jack 422 is adjacent to the second arc-shaped tooth 40 of the second adjusting plate 4. On the rear side of the second adjusting plate 4 located at the rear side, there is also a fourth limiting post 412 protruding backward at a position adjacent to the second axis. On the outer peripheral wall of the end of the fourth limiting post 412, there is also a fourth limiting stop 64 extending radially outward. Specifically, the fourth limiting stop 64 is a fourth gasket connected to the end wall of the fourth limiting post 412 by a screw 432, and the diameter of the fourth gasket is larger than the outer diameter of the fourth limiting post 412. The fourth gasket and the screw 432 can also be an integral part, that is, a screw component with a gasket structure is adopted.

[0041] See Figure 2, the first shelf 70 is disposed between the front and rear first adjusting plates 3. Specifically, the first shelf 70 is generally U-shaped and includes a first cross bar 71 and two first vertical bars 72 respectively connected to both ends of the first cross bar 71 and arranged side by side. The first cross bar 71 extends in the front-rear direction. The middle parts of the two first vertical bars 72 each have a first bent portion 720 bent in a circle and are respectively wound around the above-mentioned first limiting post 311 and second limiting post 312 through the first bent portion 720. The end parts of the two first vertical bars 72 are respectively inserted into the first jack 321 and the second jack 322, whereby the fixation of the first shelf 70 relative to the two first adjusting plates 3 can be achieved. Due to the limiting effect of the first gasket and the second gasket on the two first adjusting plates 3, the two first vertical bars 72 of the first shelf 70 are not easily detached from the corresponding first limiting post 311 and second limiting post 312. The second shelf 80 is disposed between the front and rear second adjusting plates 4. Specifically, the second shelf 80 is generally U-shaped and includes a second cross bar 81 and two second vertical bars 82 respectively connected to both ends of the second cross bar 81 and arranged side by side. The second cross bar 81 extends in the front-rear direction. The middle parts of the two second vertical bars 82 each have a second bent portion 820 bent in a circle and are respectively wound around the above-mentioned third limiting post 411 and fourth limiting post 412 through the second bent portion 820. The end parts of the two second vertical bars 82 are respectively inserted into the third jack 421 and the fourth jack 422, whereby the fixation of the second shelf 80 relative to the two second adjusting plates 4 can be achieved. Due to the limiting effect of the third gasket and the fourth gasket on the two second adjusting plates 4, the two second vertical bars 82 of the second shelf 80 are not easily detached from the corresponding third limiting post 411 and fourth limiting post 412.

[0042] The two first vertical bars 72 of the first shelf 70 are divided into two rod bodies with the first bent portion 720 as the center, and the two rod bodies are arranged at an angle. Among them, the part of the rod body connected to the first cross bar 71 extends obliquely upward. The two second vertical bars 82 of the second shelf 80 are divided into two rod bodies with the second bent portion 820 as the center, and the two rod bodies are arranged at an angle. Among them, the part of the rod body connected to the second cross bar 81 extends obliquely upward. The parts to be sprayed can be placed on the first cross bar 71 and the second cross bar 81. The above-mentioned first shelf 70 and second shelf 80 can rotate with the corresponding first adjusting plate 3 and second adjusting plate 4 to change the opening size between the first shelf 70 and the second shelf 80, so as to place parts of different sizes.

[0043] After the adjustment plate assembly is adjusted in place, it is locked by the locking assembly so as to be maintained at the corresponding opening angle for placing parts. The locking assembly includes a locking member movably disposed on the connecting module 2 in a manner capable of moving back and forth relative to the connecting module 2. With the change of its front and back positions, the locking member has a locking state capable of pressing on the first adjustment plate 3 and the second adjustment plate 4 to limit the rotation of the first adjustment plate 3 and the second adjustment plate 4, and an unlocking state of releasing the pressure on the first adjustment plate 3 and the second adjustment plate 4 to allow the first adjustment plate 3 and the second adjustment plate 4 to rotate freely. The locking member includes a first knob 91 and a second knob 92. The first knob 91 is threadedly connected to the upper region of the front side wall of the connecting module 2 at the meshing position of the first adjustment plate 3 and the second adjustment plate 4. When the first knob 91 is tightened and adjusted, it can simultaneously press on the first adjustment plate 3 and the second adjustment plate 4 on the front side, so that the first adjustment plate 3 and the second adjustment plate 4 cannot rotate. The second knob 92 is connected to the upper region of the rear side wall of the connecting module 2 at the meshing position of the first adjustment plate 3 and the second adjustment plate 4. When the second knob 92 is tightened and adjusted, it can simultaneously press on the first adjustment plate 3 and the second adjustment plate 4 on the rear side, so that the first adjustment plate 3 and the second adjustment plate 4 cannot rotate. The tightening direction or the loosening direction of the first knob 91 and the second knob 92 is exactly opposite. Thus, it is convenient for the user to operate with both hands simultaneously and conforms to the operation habit. In order to avoid the problem of slipping during the operation of the above two knobs, the outer peripheral walls of the first knob 91 and the second knob 92 are both provided with anti-slip threads. The bottoms of the main bodies of the first knob 91 and the second knob 92 are both provided with copper inserts to prevent the problem of the threads of the knobs from slipping.

[0044] In this embodiment, in order to prevent the user from pinching their hands when operating the above-mentioned first knob 91 or second knob 92 and touching the arc teeth of the first adjustment plate 3 and the second adjustment plate 4, at least one of the front side wall and the rear side wall of the connecting module 2 is further provided with a protective convex portion extending outward corresponding to the lower region of the meshing position of the first adjustment plate 3 and the second adjustment plate 4. Among them, the protective convex portion located on the front side wall of the connecting module 2 is denoted as the first protective convex portion 93a, and the protective convex portion located on the rear side wall of the connecting module 2 is denoted as the second protective convex portion 93b. The first protective convex portion 93a and the second protective convex portion 93b can both adopt structures such as convex columns and plates, as long as they do not interfere with the adjustment plate and can play a role of isolation and protection. As Figure 2 shown, in this embodiment, a circular convex column is preferably used as the protective convex portion.

[0045] In this embodiment, the first adjusting plate 3 and the second adjusting plate 4 arranged in sequence from left to right are meshed through corresponding arc-shaped teeth. By rotating the first adjusting plate 3 and the second adjusting plate 4, the opening degree between the first shelf 70 and the second shelf 80 can be adjusted. After adjusting to the predetermined opening degree, it is then locked by the locking component, so that the first shelf 70 and the second shelf 80 can be maintained at this opening angle, and then parts of corresponding sizes can be placed. This adjustable spraying swing frame is convenient and easy to operate during the opening degree adjustment process, and can effectively improve the spraying efficiency.

[0046] On the basis of the above embodiments, other embodiments can be obtained by replacing and improving relevant technical features. For example, only one of the first rotating shaft 51 and the second rotating shaft 52 on the connecting module 2 can be retained, and the synchronous rotation of the two first adjusting plates 3 and the second adjusting plates 4 can still be achieved. For example, the two first adjusting plates 3 can be connected through the first rotating shaft 51, the second rotating shaft 52 can be omitted, and the two second adjusting plates 4 can be directly rotatably installed at the front and rear two ports of the hole 20 of the connecting module 2. Another example is that one of the two first adjusting plates 3 on the front and rear sides can be integrally designed with the first rotating shaft 51, that is, one of the first adjusting plates 3 is an adjusting plate (gear piece) with a rotating shaft, and the other is a conventional separate gear piece structure.
