[0032] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Herein, the extension direction of the hanging plate 12 is defined as the “left-right direction”, and the extension direction of the support rod 2 is defined as the “front-back direction”; the support rods 2 connected to the same hanging plate 12 form a row.

[0034] Please refer to Figure 1-Figure 4 , Figure 1 A structural schematic diagram of a specific embodiment of the fixing tool provided by the utility model; Figure 2 for Figure 1The state diagram of the fixed tooling when fixing the workpiece to be processed; Figure 3 for Figure 2 Structural diagram of the second angle; Figure 4 for Figure 3 A partial enlarged view of .

[0035] The utility model provides a fixed tool, comprising two hanging frames 1 arranged opposite to each other, the hanging frames 1 comprising a hanging frame body 11 and a hanging plate 12, the hanging frame body 11 extending in the height direction, the hanging plates 12 connected to the hanging frame body 11 and spaced apart in the height direction, the hanging plates 12 in the two hanging frames 1 are arranged correspondingly, and the hanging plates 12 are provided with first mounting portions spaced apart in the length direction;

[0036] It also includes a support rod 2 and a connecting part 3, both ends of the support rod 2 are installed on the corresponding first mounting parts and are detachable, the support rod 2 is provided with second mounting parts spaced apart along the length direction, the connecting part 3 is connected to the corresponding second mounting part and is detachable, and the connecting part 3 is constructed to fix the workpiece 01 to be processed.

[0037] The fixing tool of the utility model fixes the workpiece 01 to be processed by the connecting portion 3 connected to the support rod 2. According to the types and specifications of the workpiece 01 to be processed, the same workpiece 01 to be processed can be fixed by at least one connecting portion 3. For example, when the same workpiece 01 to be processed is fixed by one connecting portion 3, the connecting portion 3 is located above the workpiece 01 to be processed; Figure 4 As shown, in this embodiment, the same workpiece 01 to be processed is fixed by four connecting parts 3, wherein two connecting parts 3 are located above the workpiece 01 to be processed, and two connecting parts 3 are located below the workpiece 01 to be processed, the upper two connecting parts 3 are connected to two adjacent support rods 2 at the upper ends, and the lower two connecting parts 3 are connected to two adjacent support rods 2 at the lower ends.

[0038] It can be understood that in order to meet the fixing requirements of different types and specifications of workpieces 01 to be processed, it is required that the fixing space provided by the fixing tool can be adaptively adjusted according to the size of the workpiece 01 to be processed, wherein the adjustment direction includes the height direction, the left-right direction and the front-back direction, specifically:

[0039] In the fixed state, the workpiece 01 to be processed is located between two adjacent rows of support rods 2 in the height direction; therefore, in order to meet the fixing requirements of workpieces 01 to be processed of different types and specifications in the height direction, the spacing between two adjacent rows of support rods 2 needs to be adjusted according to the size of the workpiece 01 to be processed in the height direction. In this embodiment, the hanging frame 1 is provided with hanging plates 12 distributed at intervals along the height direction, and the hanging plates 12 are provided with a first mounting portion. Both ends of the support rod 2 are mounted on the corresponding first mounting portions and are detachable. In this way, when the size of the workpiece 01 to be processed in the height direction is smaller than the spacing between two adjacent hanging plates 12, two adjacent rows of support rods 2 can be connected to two adjacent hanging plates 12. Figure 2-Figure 4 If the height dimension of the workpiece to be processed 01 is greater than the spacing between two adjacent hanging plates 12, the two adjacent rows of support rods 2 can be connected to the two hanging plates 12 alternately, combined with Figure 2-Figure 4 It is understood that this is equivalent to detaching the support rods 2 in the second and fourth rows from top to bottom to meet the fixing requirements of larger-sized workpieces 01 to be processed.

[0040] Furthermore, in order to ensure that the workpiece 01 to be processed has sufficient fixed space in the left and right directions, in this embodiment, the hanging plate 12 is provided with first mounting portions spaced apart along its length direction, and both ends of the support rod 2 are mounted on the corresponding first mounting portions and are detachable. In other words, the position where the support rod 2 is connected to the hanging plate 12 is adjustable along the length direction of the hanging plate 12, such as Figure 1-Figure 4 As shown, in the present embodiment, three slots 12a are spaced apart between two adjacent support rods 2. In practice, if the size of the workpiece 01 to be processed is reduced, the two adjacent support rods 2 can be adjusted to be closer to each other, such as two adjacent support rods 2 are spaced apart by two slots 12a; if the size of the workpiece 01 to be processed is increased, the two adjacent support rods 2 can be adjusted to be away from each other, such as five slots 12a are spaced apart between two adjacent support rods 2, so as to meet the fixing requirements of workpieces 01 to be processed of different specifications in the left and right directions.

[0041] At the same time, in order to ensure that the workpiece 01 to be processed has sufficient fixing space in the front-to-back direction, in this embodiment, the support rod 2 is provided with second mounting parts spaced apart along its length direction, and the connecting part 3 is connected to the corresponding second mounting part and is detachable, that is, the spacing between adjacent connecting parts 3 in the front-to-back direction can be adaptively adjusted according to the size of the workpiece 01 to be processed in the front-to-back direction. If the size of the workpiece 01 to be processed in the front-to-back direction increases, part of the connecting part 3 can be detached to meet the fixing requirements of workpieces 01 to be processed of different specifications in the front-to-back direction.

[0042] To sum up, the fixing tool of the utility model adopts a new structural design, so that the installation position of the connecting part 3 can be flexibly adjusted in the entire space, which meets the fixing requirements of different types and specifications of workpieces 01 to be processed, expands the application scope of the fixing tool of the utility model, reduces the number of fixing tools required, and reduces costs.

[0043] In this embodiment, the hanging plate 12 is fixedly connected to the hanging frame body 11. In practice, the position where the hanging plate 12 is connected to the hanging frame body 11 can be adjusted in the height direction, such as the hanging plate 12 is slidably installed on the hanging frame body 11, and then locked by a locking member. When the locking member is released, the hanging plate 12 can slide in the extension direction of the hanging frame body 11, that is, slide in the height direction. In this way, by adjusting the spacing between two adjacent hanging plates 12, the spacing between two adjacent rows of support rods 2 can be adjusted.

[0044] Please refer to Figure 1 , Figure 5 and Figure 6 , Figure 5 for Figure 1 A schematic diagram of the structure of the second angle of the fixed tooling; Figure 6 for Figure 1 A partial enlarged view of the fixed tooling.

[0045] In this embodiment, the hanging plate 12 is provided with slots 12a spaced apart along the length direction, the upper end of the slots 12a is an open end, the two ends of the support rod 2 are inserted into the corresponding slots 12a and are detachable, and the slots 12a form the aforementioned first mounting portion.

[0046] As set above, this embodiment realizes the connection of the support rod 2 by inserting and fitting the support rod 2 with the slot 12a, and the connection method is simple and convenient for disassembly and assembly. In practice, the thickness of the support rod 2 can be slightly larger than the width of the slot 12a, that is, the support rod 2 and the slot 12a adopt an interference fit to ensure that the connection between the hanging plate 12 and the support rod 2 is reliable and prevent the support rod 2 from being separated from the inside of the slot 12a. Of course, the interference between the support rod 2 and the slot 12a should not be too large to ensure the convenience of the support rod 2 when disassembling and assembling.

[0047] It can be understood that the interference fit between the support rod 2 and the slot 12a is mainly to achieve the axial limit of the support rod 2 and prevent the support rod 2 from axially disengaging from the inside of the slot 12a. In practice, there are many ways to achieve the axial limit of the support rod 2, such as the two ends of the support rod 2 have protrusions, after the support rod 2 is inserted into the corresponding slot 12a, the protrusion is located on the outside of the corresponding hanging plate 12, and the thickness of the protrusion is greater than the width of the slot 12a, that is, the protrusion cannot pass through the inside of the slot 12a, so that the two protrusions can achieve the axial limit of the support rod 2 and prevent the support rod 2 from axially disengaging from the inside of the slot 12a. Of course, after the above protrusions are set, the support rod 2 and the slot 12a can be clearance-fitted for easy disassembly and assembly.

[0048] like Figure 6 As shown, in this embodiment, both ends of the support rod 2 are respectively provided with limiting grooves 2a, the lower end of the limiting groove 2a is an open end, and the hanging plate 12 at the corresponding end is at least partially inserted into the limiting groove 2a along the height direction.

[0049] In this way, the two ends of the support rod 2 are fixed by the corresponding limit grooves 2a and the insertion fit of the hanging plate 12, so as to realize the axial limit of the support rod 2 and ensure the reliable connection between the hanging plate 12 and the support rod 2. Similarly, in this embodiment, the support rod 2 and the slot 12a can be fitted with clearance to facilitate disassembly and assembly.

[0050] Please continue to refer to Figure 1 , Figure 4 and Figure 7 , Figure 7 for Figure 1 Schematic diagram of the structure of the third angle of the fixed tooling.

[0051] In this embodiment, the support rod 2 is provided with lifting holes 2b spaced apart along the length direction, and also includes a hook, the connecting portion of the hook is connected to the inside of the lifting hole 2b and is detachable, the hooking portion of the hook is used to connect the workpiece 01 to be processed, the lifting hole 2b forms the aforementioned second mounting portion, and the hook forms the aforementioned connecting portion 3.

[0052] It can be seen that in Figure 4 In the illustrated embodiment, the workpiece 01 to be processed is a bearing retainer, which has retaining holes distributed along the circumferential direction. Therefore, the connecting portion 3 adopts a hook structure, and the hooking portion of the hook passes through the retaining hole of the bearing retainer to achieve connection with the bearing retainer. The connecting portion 3 has a simple structure and a reliable connection, which facilitates the installation and disassembly of the bearing retainer.

[0053] In practice, the fixing tool of the utility model can not only meet the fixing requirements of the above-mentioned bearing retainer, but also be applicable to other different types and specifications of workpieces to be processed 01. At the same time, the specific structure of the connecting part 3 can be adaptively adjusted according to the structure of the workpiece 01 to be processed.

[0054] Please continue to refer to Figure 4 In this embodiment, except for the support rods 2 located in the top row and the bottom row, in the remaining support rods 2, the same lifting hole 2b is connected to two connecting parts 3, one of which extends upward and the other extends downward.

[0055] Among them, the upwardly extending connection part 3 participates in fixing the upper workpiece to be processed 01, and the downwardly extending connection part 3 participates in fixing the lower workpiece to be processed 01. The two connection parts 3 share the same lifting hole 2b, which can reduce the number of lifting holes 2b set in the support rod 2, facilitate processing, and avoid the influence of too many lifting holes 2b on the structural strength of the support rod 2. The size of the support rod 2 can also be reduced to reduce the structural cost.

[0056] In practice, when the same workpiece 01 to be processed is fixed by only one connecting portion 3, the same lifting hole 2b only needs to be connected to one connecting portion 3 and extend downward.

[0057] Please continue to refer to Figure 1 In this embodiment, a lifting hole 11a is correspondingly provided at the upper end of the lifting frame body 11. Thus, when the position of the fixed tooling needs to be moved, the lifting device can be connected to the fixed tooling through the two lifting holes 11a to ensure the stability of the fixed tooling during the transfer process.

[0058] Specifically, in this embodiment, the main body 11 of the hanging frame includes a main body 111, the main body 111 extends in the height direction, and the hanging plate 12 is connected to the main body 111.

[0059] The main body 111 includes a hanging part 111a located at the upper end, and the hanging part 111a has a groove with an open end. The hanging frame body 11 also includes a fixing plate 112, which is detachably connected to the open end of the hanging part 111a. The hanging part 111a and the fixing plate 112 enclose a hanging hole 11a.

[0060] In practical applications, the hoisting equipment can be connected to the fixed fixture through the hanging beam, that is, when the position of the fixed fixture needs to be moved, the hanging beam can pass through the two hanging holes 11a to achieve a reliable connection between the hanging beam and the fixed fixture. In order to facilitate the installation of the hanging beam, the present embodiment sets the hanging frame body 11 as a split structure of a main body 111 and a fixed plate 112. When the hanging beam needs to be installed, the fixed plate 112 can be disassembled first to expose the open end of the hanging part 111a. After the hanging beam enters the groove from the open end of the hanging part 111a, the fixed plate 112 is connected to the hanging part 111a. The hanging part 111a and the fixed plate 112 are enclosed to form a closed hanging hole 11a to prevent the hanging beam from detaching.

[0061] It can be seen that the split structure of this embodiment is convenient for installing the hanging beam and can ensure the installation reliability of the hanging beam. In practice, the directions of the opening ends of the two hanging parts 111a should be consistent, either toward the upper end or toward the left and right directions.

[0062] In practice, it is also feasible to adopt an integrated structure for the lifting frame body 11. In this case, the fixed tooling can be transferred without using a lifting beam. For example, the lifting equipment includes two hooks, and the hooks are connected to the lifting holes one by one to achieve a stable connection between the lifting equipment and the fixed tooling.

[0063] Furthermore, in this embodiment, the hanging frame body 11 further includes a threaded connector 113, and the fixing plate 112 is connected to the hanging portion 111a via the threaded connector 113, so that the connection is reliable and easy to disassemble.

[0064] Specifically, the open end wall of the lifting part 111a is provided with two threaded connection holes, and the two threaded connection holes are located on both sides of the opening. Through holes are provided at both ends of the fixing plate 112 at positions corresponding to the threaded connection holes. Threaded connecting parts 113 such as screws pass through the through holes and are screwed and fixed with the corresponding threaded connection holes to achieve the fixation of the fixing plate 112 and the lifting part 111a.

[0065] In practice, there is no limitation on the connection method between the fixing plate 112 and the hanging portion 111 a . For example, the fixing plate 112 and the hanging portion 111 a may be fixed by snap connection.

[0066] In this embodiment, the main body 111 is a square tubular structure to ensure the structural strength of the main body 111 .

[0067] In addition, the materials of the components in the fixing fixture, such as the main body 111 , the fixing plate 112 , the hanging plate 12 and the support rod 2 , include but are not limited to stainless steel.

[0068] The utility model also provides a phosphating device, comprising the aforementioned fixing tool and phosphating equipment, wherein the fixing tool is configured to fix a workpiece 01 to be processed, and the phosphating equipment is configured to perform phosphating treatment on the workpiece 01 to be processed.

[0069] The phosphating device of the utility model includes the aforementioned fixing tool, and therefore has the same technical effect as the aforementioned fixing tool, which will not be described in detail here.

[0070] It can be understood that, in practice, the fixing fixture of the present application can be applied not only to phosphating equipment, but also to other application scenarios where the workpiece 01 to be processed needs to be fixed.

[0071] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
