Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to an assembled circular ring parts clamp. Background Art

[0002] Ring parts are commonly used in mechanical equipment and engineering projects. They have various uses, including connection, support and sealing. These parts are usually made of metal or plastic, have a ring shape, and can be used for bearings, seals, gaskets and other applications.

[0003] In the existing technology, when it is necessary to process the circular ring parts, a fixture may be needed. However, in the clamping process, since the processing belongs to the form of assembly line, in the process of assembling the parts, due to the bolt-type fixing method, the bolts need to be installed and removed one by one, which increases the operation time. In assembly line production, time is a very precious resource, so this fixing method may increase the overall production cycle and affect production efficiency. In addition, due to long-term repetitive operations, it may also cause fatigue and wrong operation of the operator, increasing the risk of human error. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide an assembled circular ring parts clamp.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an assembled circular ring part clamp, comprising: a clamping mechanism, the inner wall of the clamping mechanism is provided with a buffer mechanism, the clamping mechanism comprises a base plate, a fixing frame is provided on the top of the base plate, a limiting groove is provided on the inner wall of the fixing frame, two connecting rods are provided on the surface of the limiting groove, a gear is provided on the inner side of one end of the connecting rod, a turning handle is provided on one side of the gear, a bearing is provided on one end of the side of the turning handle, a side plate is provided on the outer side of the bearing, a ratchet is provided inside the top end of the side plate, and a semicircular block is provided at the other end of the connecting rod.

[0006] As a preferred embodiment, the buffer mechanism includes a pad, one side of the pad is fixedly connected to one end of the spring sheet, the other end of the spring sheet is fixedly connected to one side of the inner wall of the semicircular block, and the inner wall of the semicircular block corresponds to the outer side of the pad.

[0007] As a preferred implementation, the top of the bottom plate is fixedly connected to the bottom end of the fixing frame, and one side of the fixing frame is clamped with one end of the side surface of the clamping plate.

[0008] As a preferred embodiment, the side surface of the connecting rod is slidably connected to the inner surface of the limiting groove, the inner side of one end of the connecting rod is meshingly connected to the outer side of the gear, and one side of the gear is fixedly connected to one end of the side surface of the handle.

[0009] As a preferred embodiment, the outer side of the turning handle is engaged with one end of the pawl, one side of the pawl is movably connected to the inside of one end of the side plate, and the inside of the side plate is fixedly connected to the outer ring of the bearing.

[0010] As a preferred embodiment, the inner ring of the bearing is fixedly connected to the outer side of one end of the handle, and one end of the handle is connected to the inside of the side plate.

[0011] As a preferred implementation, one end of the connecting rod and one end of the semicircular block are clamped together.

[0012] As a preferred implementation, the interior of the connecting rod and the semicircular block are both threadedly connected to the outer side of the bolt.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The annular parts to be clamped are fitted with the splint. At this time, the handlebar gear begins to mesh with the teeth of the rear half of the connecting rod, so that the connecting rod moves and approaches the annular direction, and finally the semicircular block approaches the parts to restrict and fix them. In addition, the ratchet is engaged with the ratchet teeth on the handlebar to prevent the handlebar from rotating freely after fixation, which causes the semicircular block on the connecting rod to be unable to maintain consistent clamping force. In this way, it can be quickly clamped and loosened during the processing process;

[0015] 2. By designing a spring sheet on the inner side of the semicircular block, one end of which is connected to a pad, the presence of the spring sheet can increase the clamping force during the clamping process between the semicircular block and the annular parts, ensuring that the annular parts are firmly fixed on the semicircular block. This can prevent the parts from loosening or shifting and improve stability during assembly or operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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 in 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.

[0024] Example 1

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an assembled circular part clamp, comprising: a clamping mechanism 1, the inner wall of the clamping mechanism 1 is provided with a buffer mechanism 2, the clamping mechanism 1 comprises a bottom plate 11, a fixing frame 12 is provided at the top of the bottom plate 11, a limiting groove 13 is provided on the inner wall of the fixing frame 12, two connecting rods 14 are provided on the surface of the limiting groove 13, a gear 16 is provided on the inner side of one end of the connecting rod 14, a turning handle 17 is provided on one side of the gear 16, a bearing 110 is provided on one end of the side of the turning handle 17, a side plate 19 is provided on the outer side of the bearing 110, a ratchet 18 is provided inside the top end of the side plate 19, a semicircular block 15 is provided on the other end of the connecting rod 14, the top of the bottom plate 11 is fixedly connected to the bottom end of the fixing frame 12, and the fixing frame One side of 12 is clamped with one end of the side of the splint 111, the side of the connecting rod 14 is slidably connected with the inner surface of the limiting groove 13, the inner side of one end of the connecting rod 14 is meshed with the outer side of the gear 16, one side of the gear 16 is fixedly connected with one end of the side of the turning handle 17, the outer side of the turning handle 17 is clamped with one end of the pawl 18, one side of the pawl 18 is movably connected with the inside of one end of the side plate 19, the inside of the side plate 19 is fixedly connected with the outer ring of the bearing 110, the inner ring of the bearing 110 is fixedly connected with the outer side of one end of the turning handle 17, one end of the turning handle 17 is connected with the inside of the side plate 19, one end of the connecting rod 14 is clamped with one end of the semicircular block 15, and the inside of the connecting rod 14 and the semicircular block 15 are both threadedly connected with the outer side of the bolt 112.

[0026] In this embodiment, when the staff is in use, the annular part to be clamped is fitted with the clamping plate 111. At this time, the handle 17 is rotated by manual operation, so that the gear 16 begins to mesh with the teeth of the rear half of the connecting rod 14. In this process, in order to reduce the wear of the handle 17, the bearing 110 installed at one end of the side of the handle 17 can play this role. As the gear 16 meshes with the teeth on the connecting rod 14, the connecting rod 14 moves and approaches the annular direction, and finally the semicircular block 15 approaches the part to restrict and fix it. After fixation, since the outer ring of the handle 17 is designed with ratchet teeth, the pawl 18 will continuously engage with it during the rotation process to prevent the handle 17 from rotating freely after fixation, resulting in the semicircular block 15 on the connecting rod 14 being unable to maintain a consistent clamping force. In this way, the stability of the clamping can be ensured, and during production and processing, a faster clamping and fixing process can be achieved to improve production efficiency.

[0027] Secondly, as time goes by, the surface of the semicircular block 15 will be worn to a certain extent after a long period of clamping work, and this wear will make its surface smooth. Therefore, by removing the bolt 112 from one end of the connecting rod 14, the control of the semicircular block 15 is released, and the original semicircular block 15 can be replaced at this time. By replacing the worn semicircular block 15, the clamping force can be guaranteed to be consistent, ensuring the fixing effect of the parts. The same is true for replacing the splint 111. You only need to use force to take the splint 111 out of the fixed frame 12.

[0028] Example 2

[0029] like Figure 1 - Figure 4 As shown, the buffer mechanism 2 includes a pad 21, one side of the pad 21 is fixedly connected to one end of the spring 22, and the other end of the spring 22 is fixedly connected to one side of the inner wall of the semicircular block 15, and the inner wall of the semicircular block 15 corresponds to the outer side of the pad 21.

[0030] In this embodiment, a spring clip 22 is designed on the inner side of the semicircular block 15, and one end of the spring clip 22 is connected to a pad 21. During the clamping process between the semicircular block 15 and the annular parts, the presence of the spring clip 22 can increase the clamping force and ensure that the annular parts are firmly fixed on the semicircular block 15. This can prevent the parts from loosening or shifting and improve the stability during assembly or operation. The spring clip 22 contacts the inner side of the semicircular block 15 and provides additional friction through pressure, thereby reducing the friction and wear between the semicircular block 15 and the annular parts, which helps to extend the service life of the clamping device and reduce maintenance costs.

[0031] Working principle:

[0032] like Figure 1- Figure 4 As shown, when the utility model is used, according to the needs of the user, the annular part to be clamped is fitted with the clamping plate 111. At this time, the turning handle 17 is rotated by human operation, so that the gear 16 begins to mesh with the teeth of the rear half of the connecting rod 14, so that the connecting rod 14 moves and approaches the annular direction, and finally the semicircular block 15 approaches the part to restrict and fix it. After being fixed, since the outer ring of the turning handle 17 is designed with ratchet teeth, the ratchet 18 will continuously engage with it during the rotation process;

[0033] By designing a spring piece 22 on the inner side of the semicircular block 15, one end of the spring piece 22 is connected to a pad 21. During the clamping process between the semicircular block 15 and the annular parts, the presence of the spring piece 22 can increase the clamping force and ensure that the annular parts are firmly fixed on the semicircular block 15. This can prevent the parts from loosening or shifting and improve the stability during assembly or operation.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
