[0001] The utility model relates to the field of cam lifting mechanism assembly, in particular to an assembly tool for a roller with a cam. Background Art

[0002] A jacking transfer machine is a common device in transport equipment, with a wide range of applications. When raised, it can change the conveying direction of items, move items from a fork into or out of the main conveyor line, and facilitate the transport and transfer of goods between different heights or locations. When transfer is not required, it can be lowered without affecting the original conveying of items. For example, the extra-long conveyor fork embedded transfer machine with application number 202322056993.1 demonstrates the use of a cam roller to control the lifting and lowering of the transfer machine.

[0003] For example, patent application number 202223139005.1 discloses an assembly tool for a cam lift roller on a transfer machine, which ensures good synchronization of the two cams during the assembly of the cam lift mechanism. However, the assembly tool does not define the position of the cam in the axial direction of the roller body. This results in an inability to ensure that the cam is properly positioned in this direction during the initial welding of the cam, which reduces the pass rate of the cam lift roller. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembly tool for a roller with cams, which can ensure that the two groups of cams have good synchronization after being fixed before the welding work is carried out, and ensure that the two groups of cams are placed in place in the axial direction of the roller body, thereby further improving the processing accuracy of the roller with cams.

[0005] The utility model is realized through the following technical solutions:

The cam roller of claim 17, wherein the first and second support brackets are configured to be aligned with the alignment requirements of the first and second support brackets, respectively. The cam rollers are configured to be aligned with the alignment requirements of the first and second support brackets, respectively. The cam rollers are configured to be aligned with the alignment requirements of the second and second support brackets, respectively.

[0007] As a further improvement of the present invention, a positioning plate is provided on the first supporting bracket and / or the second supporting bracket, and the positioning plate includes a positioning surface that conflicts with the cam, and the positioning plate is used to limit the distance between the two groups of cams and the first supporting bracket and the second supporting bracket.

[0008] As a further improvement of the present invention, the first positioning pin and / or the second positioning pin both include a pin body and an elastic component, a limit block is fixed on the pin body, one end of the elastic component acts on the limit block, and the other end acts on the first supporting bracket or the second supporting bracket to facilitate the pin body to pass through the first supporting bracket or the second supporting bracket to form the positioning end.

[0009] As a further improvement of the present invention, a limiting protrusion is provided on the outer side of the first supporting bracket and / or the second supporting bracket, and a limiting cavity is formed in the limiting protrusion for accommodating the pin body. One end of the elastic component acts on the limiting block, and the other end acts on the limiting inner wall of the limiting cavity.

[0010] As a further improvement of the present invention, the workbench further includes a third supporting bracket, which is arranged between the first supporting bracket and the second supporting bracket and is used to support the photoelectric sensor plate mounted on the cylinder.

[0011] As a further improvement of the present invention, a positioning groove is provided on the third supporting bracket, and the positioning groove is used to adapt to the protrusion on the photoelectric sensor board.

[0012] As a further improvement of the present invention, avoidance sections are provided at both ends of the main rod body, one end of the avoidance section is connected to the main rod body, and the other end is connected to the positioning kit. When the cam roller is placed in the assembly tooling, the avoidance section causes the main rod body to move away from the cam roller.

[0014] As a further improvement of the present invention, the telescopic structure includes a telescopic component arranged between the main rod body and at least one of the positioning kits.

[0015] As a further improvement of the present invention, the first supporting groove and the second supporting groove include a groove bottom supporting surface and a side positioning surface, wherein the groove bottom supporting surface and the side positioning surfaces connected to both sides of the groove bottom supporting surface together form a accommodating space opening upward, and the structure of the groove bottom supporting surface is adapted to the cylinder.

[0016] The beneficial effect of the present invention is that, through the cooperation between the first support bracket, the second support bracket, and the positioning rod, the cam is accurately and properly fixed on the cylinder body, effectively preventing the cam from shifting during the initial welding process, which would cause the welded cam roller to fail to meet the requirements. Moreover, under the structure of the present invention, after the initial welding of the cam is completed, the first and second positioning pins can be removed from the positioning holes, leaving only the positioning rod to assist in fixing the cam. At this time, the cam roller can be rotated, so that the connection between the cam and the cylinder body, which was previously inconvenient to weld, is rotated to an area that is convenient for construction workers to operate, which is more conducive to the development of welding work.

[0024] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0025] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0026] The main construction object of the assembly tool in this embodiment is the cam roller. The specific structure of the cam roller is as follows: Figure 1 As shown, it primarily comprises a barrel A-2, a sprocket mounted at one end of barrel A-2, and two sets of cams A-1 mounted and secured to barrel A-2. Some of the cam-mounted rollers are also fitted with photoelectric sensor plates A-3. The core structure of the cam-mounted roller lies in the two sets of cams A-1. As barrel A-2 rotates, the two sets of cams A-1 utilize their convex portions to raise and lower the transfer mechanism. Each set of cams A-1 is prefabricated with positioning holes A-1-3. In this embodiment, the space between the two sets of cams A-1 is considered the inner side, while the area outside the two sets of cams A-1 is considered the outer side. Therefore, the positioning holes A-1-3 on a single set of cams A-1 have a second positioning opening A-1-2 formed near the inner side and a first positioning opening A-1-1 formed near the outer side.

[0027] Example 1:

[0028] This embodiment provides an assembly tool for a cam roller, used to position two sets of cams A-1 on a cylinder A-2, facilitating welding of the cams A-1 to the cylinder A-2 to form the cam roller. The assembly tool primarily comprises a workbench 1, first and second support brackets 2 and 3 spaced apart on the workbench 1, and a positioning rod 4. The area between the first and second support brackets 2 and 3 is considered the inner side, while the area outside the first and second support brackets 2 and 3 is considered the outer side.

[0029] like Figure 2 、 4As shown, the first support bracket 2 is provided with a first support groove 201 and a first positioning pin 202, and the second support bracket 3 is provided with a second support groove 301 and a second positioning pin 302, wherein the first support groove 201 and the second support groove 301 are respectively used to support the two ends of the cylinder A-2, thereby achieving a supporting effect on the cylinder A-2 as a whole. In this embodiment, after the first positioning pin 202 and the second positioning pin 302 are respectively inserted into the first support bracket 2 and the second support bracket 3 from the outside, corresponding positioning ends 5 are formed on the inside. When the various components with the cam roller are placed on the assembly tool, the positioning end 5 is inserted into the positioning hole A-1-3 of the cam A-1 through the first positioning port A-1-1. Under this structure, the convex parts of the two groups of cams A-1 are ensured to be synchronized, and when the cylinder A-2 produces the same amount of rotation, the convex parts of the two groups of cams A-1 rotate synchronously.

[0030] In this embodiment, Figure 3 、 4 As shown, the positioning rod 4 includes a main rod body 401, a telescopic structure 402, and positioning kits 403 disposed at both ends of the main rod body 401. The positioning kits 403 include a positioning protrusion 403-1 and a positioning block 403-2. In this embodiment, the positioning rod 4 is disposed on the inner side. Therefore, when fixing the cam A-1, the telescopic structure 402 reduces the distance between the two sets of positioning kits 403 until the positioning protrusion 403-1 can be placed in the second positioning opening A-1-2. The distance between the two sets of positioning kits 403 is then increased so that the positioning protrusion 403-1 can pass through the second positioning opening A-1-2 and insert into the positioning hole A-1-3. The two positioning blocks 403-2 contact the inner sides of the two sets of cams A-1, driving the two sets of cams A-1 to mate with the first support bracket 2 and the second support bracket 3, respectively. With this structure, the positioning rod 4 can ensure that the two sets of cams A-1 are fixed in place in the axial direction of the cylinder A-2.

[0031] In this embodiment, the welding of the cam roller requires welding the entire cam A-1 to the barrel A-2, thus requiring a full weld around the connection between the cam A-1 and barrel A-2. In this assembly tool, after the various components of the cam roller are secured, preliminary welding can be performed on the top connection between the cam A-1 and barrel A-2. The locating ends 5 of the first and second locating pins 202 and 302 can then be removed from the locating holes A-1-3. At this point, the cam roller can be rotated, while the locating rods 4 continue to assist in securing the two sets of cams A-1. Furthermore, the operator can apply force to the locating rods 4 to drive the overall rotation of the cam roller until the unwelded connection on the cam roller is rotated to the top, allowing subsequent welding work to proceed. This process not only facilitates welding but also ensures that the locating rods 4 continue to assist in securing the cam A-1.

[0032] Preferably, if Figure 2 As shown, in this embodiment, only the second support bracket 3 is provided with a positioning plate 6, and the positioning plate 6 includes a positioning surface that conflicts with the cam A-1. When all components are placed, the positioning plate 6 is placed between the second support bracket 3 and the cam A-1, limiting the distance between the cam A-1 and the second support bracket 3, thereby achieving the effect of controlling the position of the cam A-1 in the axial direction of the cylinder A-2. Furthermore, the positioning plate 6 and the positioning block 403-2 conflict with the cam A-1 from both the inside and outside sides, completing the fixation of the position of the cam A-1 in the axial direction of the cylinder A-2.

[0033] Preferably, in this embodiment, both the first locating pin 202 and the second locating pin 302 include a pin body 7 and an elastic member 8. A limit block 701 is fixed to the pin body 7, while one end of the elastic member 8 acts on the limit block 701 and the other end acts on the first support bracket 2 and the second support bracket 3, respectively. With this structure, when no external force is applied, the pin body 7 remains inserted through the first support bracket 2 or the second support bracket 3, forming a positioning end 5 on the inner side. Therefore, when cam A-1 is being fixed, the construction worker can first align cam A-1 with the first support bracket 2 or the second support bracket 3, forcing cam A-1 to press against the positioning end 5. Then, the cam A-1 is rotated. When the first positioning opening A-1-1 rotates to the position where the positioning end 5 is located, the elastic member 8 applies force, causing the positioning end 5 to eject and insert into the positioning hole A-1-3. This produces a clicking sound, or similar, to alert the construction worker that both cams A-1 have rotated into position and are synchronized.

[0034] Preferably, in this embodiment, the outer sides of the first support bracket 2 and the second support bracket 3 are both provided with limiting protrusions 9, so the limiting protrusions 9 can be regarded as extension structures of the first support bracket 2 and the second support bracket 3. Figure 4 As shown, the limiting protrusion 9 forms a limiting cavity 901 for accommodating the pin 7. One end of the elastic member 8 acts on the limiting block 701, while the other end acts on the limiting inner wall of the limiting cavity 901, rather than directly on the bodies of the first and second support brackets 2 and 3. This structure ensures that the driven positioning end 5 always protrudes inward when not affected by external forces. The end of the pin 7 away from the positioning end 5 is connected to an operating block, which facilitates the operator to withdraw the positioning end 5 from the positioning hole A-1-3 to activate the cam A-1.

[0035] Preferably, if Figure 2As shown, the first and second supporting grooves 201 and 301 include bottom supporting surfaces 11 and side positioning surfaces 12. The bottom supporting surface 11 and the side positioning surfaces 12 connected to the bottom supporting surface 11 together form a receiving space open upward. The structure of the bottom supporting surface 11 is compatible with the cylinder A-2. This structure not only facilitates the insertion of both ends of the cylinder A-2, but also facilitates the rotation of the cylinder A-2 in the assembly tool during the welding process.

[0036] Example 2:

[0037] The difference between this embodiment and embodiment 1 is that the cam roller processed in this embodiment is provided with a photoelectric sensor plate A-3. Therefore, in this embodiment, Figure 2 As shown, the workbench 1 further includes a third support bracket 10, which is arranged between the first support bracket 2 and the second support bracket 3, and is used to support the photoelectric sensor board A-3 mounted on the cylinder A-2.

[0038] Preferably, if Figures 1 and 2 As shown, the photoelectric sensor board A-3 is provided with a corresponding protrusion, so the third support bracket 10 is provided with a positioning groove 1001, which can accommodate the embedding of the protrusion on the photoelectric sensor board A-3. At the same time, the third support bracket 10 can also fix the position of the photoelectric sensor board A-3 through the positioning groove.

[0039] Preferably, in this embodiment, the distance between the positioning hole A-1-3 on the cam A-1 and the central axis of the cylinder A-2 is smaller than the distance between the edge of the photoelectric sensor plate A-3 and the axis of the cylinder A-2, which causes the ordinary positioning rod 4 to conflict with the photoelectric sensor plate A-3. Figure 3 As shown, both ends of the main rod body 401 are provided with avoidance sections 401-1, one end of which is connected to the main rod body 401, and the other end is connected to the positioning kit 403. When the cam roller is placed in the assembly tool, the avoidance sections 401-1 can keep the main rod body 401 away from the cam roller, thereby preventing the positioning rod 4 from conflicting with the photoelectric sensor plate A-3 during installation.

[0040] Example 3:

[0041] The difference between this embodiment and embodiments 1 and 2 is that, in this embodiment, Figure 3 As shown, the telescopic structure 402 includes a telescopic rod structure 402-1 arranged on the main rod body 401. For example, in this embodiment, the telescopic rod structure 402-1 includes a spring component 402-1a, and the spring component 402-1a is placed on the outer rod 402-1b of the telescopic rod structure 402-1 and is sleeved outside the inner rod 402-1c, so that the telescopic rod structure 402-1 is always in an extended state when there is no external force.

[0042] Example 4:

[0043] The difference between this embodiment and embodiments 1 and 2 is that, in this embodiment, Figure 6 The telescopic structure 402 shown includes a telescopic component 402-2 disposed between a main rod body 401 and a positioning sleeve 403 at one end. For example, the telescopic component 402-2 comprises a guide section 402-2a connected to the main rod body 401, a spring 402-2b sleeved around the guide section 402-2a, and a cavity 402-2c disposed within a positioning protrusion 403-1 to accommodate the guide section 402-2a. When the telescopic structure 402 is extended, only a portion of the guide section 402-2a is disposed within the cavity 402-2c. However, when the telescopic structure 402 is compressed, the guide section 402-2a extends into the cavity 402-2c, shortening the overall length of the positioning rod 4. Upon removal of the external force, the spring 402-2b drives the positioning rod 4 to re-extend.

[0044] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
