Description

Technical Field

[0001] This utility model belongs to the field of pressure ring processing technology, specifically a pressure ring fixture. Background Technology

[0002] A clamping ring is a ring-shaped structural component used to fix or clamp parts, and is widely used in optical lenses. Its core function is to achieve precise fixation through a locking mechanism or elastic material, ensuring the stability and reliability of the component.

[0003] CN211979295U discloses a retaining ring and a lens. The retaining ring includes a body, which has a first end face and a second end face disposed along a first direction. A locking portion is formed on the first end face. The body has a through hole coaxial with it. The through hole has a first hole segment and a second hole segment. The second hole segment has a third opening and a fourth opening located at its two ends, which communicate with the third opening. A fourth opening is formed on the second end face, and the diameter of the fourth opening is larger than that of the third opening, so that the second hole segment is a conical surface.

[0004] In the above technical solution, by using a locking part, under the condition that it is inconvenient to rotate the pressure ring, the locking part can cooperate with the tool to make the pressure ring rotate, which facilitates the tightening / loosening of the pressure ring and the lens barrel. However, the groove on the pressure ring needs to be formed by machine tool processing. Therefore, a fixture is needed to fix the pressure ring to prevent the pressure ring from shifting during processing. Utility Model Content

[0009] The upper end of the connecting arm is provided with a pressure block, and the lower end of the connecting arm extends downward and passes through the support base. The drive mechanism is hinged to the lower end of the connecting arm. The drive mechanism is used to drive the swing of the connecting arm so that the pressure block presses the pressure ring onto the fixed block, or so that the pressure block releases the pressure ring.

[0010] In the aforementioned pressure ring clamping fixture, the support base includes a top plate and support blocks disposed at both ends of the top plate;

[0011] The fixing block is set on the top plate, and the top plate has a second strip-shaped through hole extending along the length direction of the top plate. The fixing block has an I-shaped structure, and both ends of the fixing block along its length direction have a first notch. Both first notches are located above the strip-shaped through hole.

[0015] In the aforementioned pressure ring clamping fixture, the fixing block is also provided with a fixing hole for fixing the connecting piece. The depth of the fixing hole extends along the height direction of the fixing block, and the bottom end of the fixing hole communicates with the through hole. The fixing hole is provided with a thread for screwing a second bolt to fix the connecting piece in the through hole.

[0016] In the aforementioned pressure ring fixture, the driving mechanism includes a cylinder mounted below the top plate via multiple mounting components. A connecting block is provided on the output end of the cylinder, and the lower ends of two connecting arms correspond to the two ends of the connecting block along its length. The lower ends of the connecting arms are hinged to the ends of the connecting block.

[0017] In the aforementioned pressure ring clamping fixture, the support base is also provided with multiple hollow holes.

[0018] In the aforementioned pressure ring fixture, there are multiple fixed blocks and multiple driving mechanisms. The driving mechanisms correspond one-to-one with the fixed blocks, and the fixed blocks are arranged at intervals on the top plate along the direction of the second strip-shaped through hole.

[0021] The first connecting hole corresponds to the second notch one by one. The connecting hole passes through the connecting block along the width direction of the fixing block and communicates with the second notch.

[0022] The lower end of the connecting arm is located in the second notch, and the lower end of the connecting arm is provided with a second connecting hole. The connecting shaft passes through the first connecting hole, the second notch, and the second connecting hole. The axis of the connecting shaft and the axis of the pin are on the same vertical line.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This invention achieves this by tilting the first strip-shaped through hole and using a connector to pass through the first strip-shaped through hole and the through hole, and then hinges the lower end of the connecting arm to the drive mechanism. In this way, when the drive mechanism drives the connecting arm downward, the two connecting arms can be brought closer together and the pressure ring can be pressed tightly. After the pressure ring is processed, when the drive mechanism drives the connecting arm upward, the connecting arm can be swung in opposite directions, thereby causing the pressure block to loosen the pressure ring. In this way, the pressure ring can be pressed tightly to prevent displacement of the pressure ring and the pressure ring can be easily removed by the worker. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] refer to Figures 1-6 A pressure ring clamping fixture includes a support base 1 mounted on an external machine tool and a fixing block 2 mounted on the support base 1. The fixing block 2 is provided with a positioning part 23 for placing the pressure ring 100.

[0036] It also includes connecting arms 3 and connectors 4 symmetrically arranged on both sides of the positioning part 23, and a drive mechanism 5 set at the bottom of the support base 1. The connecting arm 3 has a first strip-shaped through hole 32. The first strip-shaped through hole 32 is inclined downward from the side of the connecting arm 3 away from the positioning part 23 to the side of the connecting arm 3 close to the positioning part 23. The fixing block 2 is provided with through holes 22 corresponding to the first strip-shaped through hole 32. The connector 4 passes through the through hole 22 and the first strip-shaped through hole 32.

[0037] The upper end of the connecting arm 3 is provided with a pressure block 31, the lower end of the connecting arm 3 extends downward and passes through the support base 1, the drive mechanism 5 is hinged to the lower end of the connecting arm 3, the drive mechanism 5 is used to drive the swing of the connecting arm 3 so that the pressure block 31 presses the pressure ring 100 onto the fixed block 2, or so that the pressure block 31 releases the pressure ring 100.

[0038] It should be noted that, in the initial state, the connecting arm 3 is in the open state so that the worker can place the pressure ring 100 onto the positioning part 23.

[0039] In this design, the worker first places the pressure ring 100 on the positioning part 23, and then starts the drive mechanism 5, which drives the connecting arm 3 downward. Since the connecting piece 4 passes through the through hole and the first strip-shaped through hole 32, as the connecting arm 3 moves downward, the two pressure blocks 31 move towards each other, thus pressing the pressure ring 100 and fixing it. Then, the pressure ring 100 is processed by an external machine tool to form a groove 101. After the processing of the pressure ring 100 is completed, the drive mechanism 5 drives the two connecting arms 3 upward, while the two pressure blocks 31 move away from each other, thus loosening the pressure ring 100. Then, the worker can remove the pressure ring 100 from the positioning part 23. In this way, the pressure ring 100 can be pressed tightly to prevent displacement and the worker can easily remove the pressure ring 100.

[0040] Preferably, the support base 1 includes a top plate 11 and support blocks 12 disposed at both ends of the top plate 11;

[0041] The fixing block 2 is set on the top plate 11. The top plate 11 is provided with a second strip-shaped through hole 14 extending along the length direction of the top plate 11. The fixing block 2 has an I-shaped structure. Both ends of the fixing block 2 along its length direction have a first notch 21. Both first notches 21 are located above the first strip-shaped through hole 32. The through hole 22 passes through the fixing block 2 along the width direction of the fixing block 2 and communicates with the first notch 21. The connecting arm 3 passes through the second strip-shaped through hole 14 and the first notch 21.

[0042] Generally, connector 4 can be a pin.

[0043] Since the fixing block 2 has an I-shaped structure, specifically, the fixing block 2 has two ends along its length, and the first notch 21 is located between the two ends. The through hole 22 penetrates the fixing block 2 along its width and communicates with the first notch 21, meaning that both ends are penetrated by the through hole. It can also be understood that each of the two ends has a hole segment, and the two hole segments are the through holes mentioned in this embodiment.

[0044] Furthermore, the two support blocks 12 are used to support the top plate 11 and are mounted on the machine tool of the peripheral device. The connecting arm 3 is inserted through the second strip-shaped through hole 14 and the first notch 21, and then a pin is inserted into the through hole 22 and the first strip-shaped through hole 32 to realize the hinge of the connecting arm 3.

[0045] In this embodiment, the positioning part 23 includes a circular block 26 disposed on the top of the fixing block 2 and two positioning blocks 231 symmetrically arranged on the circular block. The positioning blocks 231 are provided with arc-shaped walls 2311 for fitting against the inner wall of the pressure ring 100.

[0046] Specifically, the pressure ring 100 has a circular structure. The arc-shaped wall 2311 on the positioning block 231 can better fit the pressure ring 100 to position it. Moreover, the positioning blocks 231 are arranged at intervals, which can prevent displacement when the groove 101 of the pressure ring 100 is machined.

[0047] Preferably, the fixing block 2 is detachably mounted on the support base 1;

[0048] The fixing block 2 is provided with a plurality of first threaded holes 24, and the support base 1 is provided with second threaded holes corresponding one-to-one with the plurality of first threaded holes 24. The fixing block 2 is fixed to the support base 1 by passing through the first threaded holes 24 and the second threaded holes (not shown in the figure) with a first bolt (not shown in the figure).

[0049] Specifically, the pressure ring 100 has different specifications. In order to facilitate replacement, the first bolt is used to pass through the first threaded hole 24 and the second threaded hole to fix the fixing block 2.

The depth of the fixing hole 25 extends along the height direction of the fixing block 2, and the bottom end of the fixing hole 25 communicates with the through hole 22. The fixing hole 25 is provided with a thread for screwing a second bolt (not shown in the figure) to fix the connector 4 in the through hole 22.

[0051] Furthermore, to prevent the connector 4 from loosening, the fixing hole 25 is connected to the through hole 22, and the second bolt is screwed into the fixing hole 25 to fix the connector 4.

[0052] In this embodiment, the drive mechanism 5 includes a cylinder 51 mounted below the top plate 11 by a plurality of mounting parts 52. A connecting block 53 is provided on the output end of the cylinder 51. The lower ends of the two connecting arms 3 correspond to the two ends of the connecting block 53 along its length direction, and the lower ends of the connecting arms 3 are hinged to the ends of the connecting block 53.

[0053] Generally, the mounting component 52 is a single column, and each cylinder 51 is connected to the bottom of the top plate 11 via four columns, thereby fixing the cylinder 51. The two symmetrical connecting arms 3 are respectively hinged to the two ends of the connecting block 53 and mate with the first strip-shaped through hole 32. In this way, when the cylinder 51 extends, the two connecting arms 3 will move upward, and the pressure block 31 will move in opposite directions, thereby releasing the pressure ring 100.

[0054] Preferably, the support base 1 is also provided with a plurality of hollow holes 13. When the pressure ring 100 is processed, liquid is added, and the hollow holes 13 are used to allow the liquid to leak down from the top plate 11.

[0055] More preferably, there are multiple fixing blocks 2 and multiple driving mechanisms 5, with each driving mechanism 5 corresponding to a fixing block 2. The fixing blocks 2 are arranged at intervals on the top plate 11 along the direction of the second strip-shaped through hole 14.

[0056] In this embodiment, there are multiple second strip-shaped through holes 14, and these multiple second strip-shaped through holes 14 are spaced apart along the width direction of the top plate 11.

[0057] Generally, in order to improve work efficiency, the second strip-shaped through holes 14 are spaced apart along the width direction of the top plate 11, and the fixing blocks 2 are arranged along the extension direction of the second strip-shaped through holes 14. In this way, the worker can place multiple pressure rings 100 on the positioning part 23 of each fixing block 2, and then drive the connecting arm 3 through the drive mechanism 5, so that the pressure block 31 can press the pressure rings 100 tightly.

[0058] Preferably, the connector 4 is a pin, the connecting block 53 is an I-shaped structure, and the connecting block 53 is provided with a second notch 531 and a first connecting hole 532. The second notch 531 is provided at both ends of the connecting block 53 along its length.

[0059] The first connecting hole 532 corresponds to the second notch 531 one by one. The connecting hole 532 passes through the connecting block 53 along the width direction of the fixing block 2 and communicates with the second notch 531.

[0060] The lower end of the connecting arm 3 is located in the second notch 531, and the lower end of the connecting arm 3 is provided with a second connecting hole (not shown in the figure). The connecting shaft 54 ​​passes through the first connecting hole 532, the second notch 531 and the second connecting hole. The axis of the connecting shaft 54 ​​and the axis of the pin are on the same vertical line.

[0061] Furthermore, the connecting block 53 has the same structure as the fixing block 2. The connecting shaft 54 ​​is inserted through the first connecting hole 532, the second notch 531 and the second connecting hole, thereby realizing the hinge of the lower end of the connecting arm 3. Moreover, the axis of the connecting shaft 54 ​​and the pin is set on the same vertical line, which can reduce the swing amplitude when the cylinder 51 drives the connecting arm 3 to move up or down.

[0062] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements or modifications can be made without departing from the principle of this utility model, and these improvements or modifications should also be considered within the protection scope of this utility model.
