Description

Technical Field

[0001] The utility model relates to the technical field of inspection tools, in particular to a buckle clamping device. Background Art

[0002] When inspecting parts with buckles, due to the presence of buckles, it is not easy to directly achieve positioning when installed on the inspection tool. Moreover, sometimes because the part covers the buckle, when positioning the buckle, it is impossible to see the fit between the buckle and the inspection tool, and blind installation is required. In the prior art, an opening and closing mechanism is mostly used to position the buckle, but this positioning method is troublesome for loading and unloading, cannot be blindly installed, and is limited by space. When loading and unloading the buckle, the opening and closing mechanism must be opened and closed. After long-term repeated use, the threaded parts used to fix the opening and closing mechanism in the closed state are prone to thread slipping and failure. Moreover, opening and closing the opening and closing mechanism both require a certain amount of operating space. When the assembly space is limited or blind installation is required, it is difficult to install the buckle into the opening and closing mechanism. Not only may the positioning not be achieved, but also the buckle may be damaged. Furthermore, after positioning the buckle, the part needs to be fixed to the inspection tool through multiple fixing structures, which is not only difficult to install but also troublesome to disassemble, time-consuming and laborious; a receiving groove is provided to cooperate with the fixed positioning body. When the receiving groove abuts against the fixed positioning body, it can be known that the sliding positioning body has moved in place, which is convenient for blind installation and more accurate in positioning the buckle.

[0003] In view of the above technical problems, as disclosed in the patent with publication number CN108747273B, a buckle positioning structure on an inspection tool is provided. When the sliding positioning body slides to enclose the fixed positioning body in the receiving groove, the buckle is positioned in the positioning space surrounded by the first positioning groove and the second positioning groove. It can accurately position the buckle of the part on the inspection tool and directly fix the part to the inspection tool at the same time, without being limited by space, and can be blindly installed. It is not only convenient for installation and operation, but also accurate in positioning; sliding the sliding positioning body to separate the first positioning groove from the second positioning groove can remove the part with the buckle, avoiding damage to the buckle, facilitating disassembly, and improving the inspection efficiency;

[0004] At present, there are usually two ways to clamp the buckle on the inspection tool: 1. Adopting a screw tightening and closing device; 2. Adopting a cantilever clamping device. However, in actual applications, both of these methods have significant defects. For the screw tightening and closing device, this method is relatively stable and not easily damaged, but it has the disadvantage of long operation time. It needs to be manually loosened and tightened. If there are many buckles on an inspection tool, a lot of time will be wasted. For the cantilever clamping device, although it can control the actions of 3 - 5 buckle seats at the same time, in actual applications, it is extremely easy to loosen and not firmly clamped, and it is particularly difficult to adjust individually.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] The present utility model provides a buckle clamping device, including a base 1. A clamping mechanism 2 for clamping a workpiece is provided on the top of the base 1. A rotating mechanism 3 for adjustment is provided inside the clamping mechanism 2. A locking mechanism 4 for extension is provided outside the rotating mechanism 3. The fixed shaft 21 in the clamping mechanism 2 is fixedly installed on one side of the base 1, and a rotating shaft 23 is installed and connected on the other side of the base 1;

[0031] A fixed clamp 22 is fixedly installed on the outside of the fixed shaft 21, a movable clamp 24 is fixedly installed on the outside of the rotating shaft 23. Clamping grooves 25 are opened on the inner sides of the movable clamp 24 and the fixed clamp 22, and a spring 26 is provided between the movable clamp 24 and the fixed clamp 22.

[0032] By pushing the connecting pipe 33 to rotate and clamping in the way that the stop pin 32 is fixed on the fixed clamp 22, the clamping function of the buckle is realized. The operation is convenient and stable, and it is not easy to be damaged; it is also relatively simple to loosen, which can improve the buckle clamping efficiency, effectively avoid problems such as loosening of the clamping device, and is easy to operate and low in price.

[0033] The fixed shaft 21 is used to stably support the fixed clamp 22, the rotating shaft 23 realizes the rotational support of the movable clamp 24, the spring 26 realizes the elastic pushing effect between the two, and the opening of the clamping groove 25 facilitates the clamping of the workpiece.

[0034] Preferably, the rotating mechanism 3 includes a limiting component, an extending component, and an external connecting component. The limiting component is arranged outside the fixed clamp 22, the extending component is arranged at the end of the limiting component, and the external connecting component is arranged at one end of the extending component.

[0035] As Figure 3 , 5 and shown in 6, the connecting rod 31 in the limiting component penetrates through the inside of the fixed clamp 22. Stop pins 32 are fixedly installed on both sides of the connecting rod 31. The connecting rod 31 is used to achieve the function of through connection, and the stop pins 32 play a role when clamping and releasing the clamping state.

[0036] As Figure 3 , 5 and shown in 6, the connecting pipe 33 in the extending component is fixedly installed at one end of the connecting rod 31. An extension rod 34 is slidably connected inside the connecting pipe 33. The connecting pipe 33 plays a role in assisting in supporting the transmission.

[0037] As Figure 3 , 5 and shown in 6, the connecting block 35 in the external connecting component is fixedly installed at one end of the extension rod 34. A connector 36 is fixedly installed at one end of the connecting block 35. An external connection groove 37 is formed on the outer side of the connector 36. The sliding connection between the extension rod 34 and the connecting pipe 33 realizes the required length for extension adjustment. The connecting block 35 cooperates with the connector 36 and the formed external connection groove 37 to connect an external driving component, so as to complete the power output operation.

[0038] Based on the combined setting of the above-mentioned clamping mechanism 2 and rotating mechanism 3, it can achieve the function of adjusting the clamping and releasing the clamping state during rotation, and can also realize the required use length, so as to adapt to the distance between the driving component and its installation;

[0039] When working:

[0040] As shown in the figure, the state presented is the clamping state. At this time, the workpiece will be clamped between the fixed clamp 22 and the moving clamp 24 and located in the clamping groove 25, and then the clamped workpiece will be detected or other operations will be performed;

[0041] When it is necessary to release the clamping state:

[0042] The joint 36 is driven to rotate directly. When the joint 36 rotates, it will also drive the connecting block 35 and the extension rod 34 to rotate together. Based on the sliding adaptation between the extension rod 34 and the connecting tube 33, the connecting tube 33 can be driven to rotate together, and the connecting tube 33 will also drive the connecting rod 31 and the stop pin 32 installed on the outside of the connecting rod 31 to rotate, thereby completing the rotation operation, and an adapter groove adapted to the connecting rod 31 and the stop pin 32 is provided on the outside of the fixed clamp 22. At this time, since the spring 26 is not squeezed, the elastic force will be released, thereby pushing the mobile clamp 24 to rotate, realizing the angle change, and completing the loose state, and the stop pin 32 is located inside the adapter groove at this time;

[0043] When clamping is required:

[0044] First, place the workpiece between the fixed clamp 22 and the movable clamp 24, and at the same time, place it in the clamp groove 25. Based on the above-mentioned loose state at this time, the connecting tube 33 and the components connected to the connecting tube 33 should be pushed to move together, so that the end of the connecting tube 33 pushes the movable clamp 24 to rotate, making it present a vertical state, and in the process of becoming the vertical state, the spring 26 will be squeezed to compress it. At this time, the connecting rod 31 and the stop pin 32 will also be driven to move and move in a horizontal state until the stop pin 32 is out of the inside of the adapter groove, and then according to the above method, the connecting tube 33 drives the connecting rod 31 and the stop pin 32 to rotate, and the transmission to Figure 7 That is, the stop pin 32 is in a vertical state when not clamped, and needs to be in a horizontal state after clamping. The stop pin 32 is clamped on one side of the fixing clamp 22 to achieve a limit blocking operation to complete the clamping of the workpiece.

[0045] When you need to adjust the required installation length and position, just adjust it as needed:

[0046] Release the locking state of the locking mechanism 4, and then directly pull the joint 36 from the outside. The joint 36 can also be used to drive the extension rod 34 to move through the connecting block 35, so that the extension rod 34 will slide inside the connecting tube 33, thereby extending and adjusting to the desired position. After adjusting to the desired position, the locking mechanism 4 can be used to lock the limit and fix it in the preset desired position.

[0047] Furthermore, the locking mechanism 4 includes a sliding component and a mounting component. The sliding component is arranged on the outside of the connecting pipe 33, and the mounting component is arranged on the outside of the sliding component.

[0048] like Figure 3 and 5As shown, the slider 41 in the sliding assembly is fixedly installed on the outside of the extension rod 34. A side plate 42 is fixedly installed on the outside of the slider 41. The slider 41 cooperates with the limit hole 45 to achieve stable sliding and limit the maximum position during the sliding process.

[0049] As Figure 3 and 5 shown, the mounting blocks 43 in the mounting assembly are fixedly installed at the top and bottom of the side plate 42. A vertical plate 44 is fixedly installed at the top of the side plate 42. Limit holes 45 are opened on both sides of the connecting pipe 33. Bolts are arranged on the inner side of the vertical plate 44. The side plate 42 is used to support and connect the mounting block 43, and the mounting block 43 is arranged to adapt to the shape of the connecting pipe 33. At the same time, the mounting block 43 can also support and fix the vertical plate 44, and the two groups of vertical plates 44 are installed and fastened by bolts.

[0050] During the actual working process:

[0051] When the extension rod 34 moves, it will directly drive the slider 41 to slide inside the limit hole 45, and play an auxiliary limiting role according to the opening of the limit hole 45. When it moves to the required position, it can be fixed directly, just as shown in the figure;

[0052] When fixing, by tightening the bolts, driving the upper and lower two groups of oppositely arranged vertical plates 44 can drive the upper and lower two groups of oppositely arranged mounting blocks 43 to tightly clamp on the outside of the connecting pipe 33, realizing the clamping operation on the connecting pipe 33, and then completing the locking operation;

[0053] When loosening and adjusting:

[0054] Just directly release the tightened state of the bolts, and then directly push and pull the sliding extension rod 34. During the sliding process, the entire locking mechanism 4 will be driven to move together. When it slides to the required position, the locking and fixing operation can be realized according to the above method.

[0055] According to the above, it can achieve the advantages of locking and positioning the positions of the connecting pipe 33 and the extension rod 34 after adjusting the extension length, not only can avoid displacement, but also ensure the subsequent connectivity and stable rotation effect.

[0056] Among them, mounting holes 6 are opened around the bottom of the base 1, and an adaptor slot is opened on the outside of the fixed clamp 22. The opening of the mounting holes 6 is conducive to fixing it on the required and preset carrier plate or equipment by means of an external screw or screw, etc. The opened adaptor slot is mainly used to adapt to the stop pin 32 to ensure that it can achieve the clamping and fixing operation and the effect of releasing and loosening according to the above operation method.

[0057] Among them, a through hole 5 is formed on the outer side of the base 1, and a sliding rod 7 is slidably connected inside the through hole 5. The formation of the through hole 5 facilitates its installation on the sliding rod 7, and the two are in a sliding connection state, so as to be able to stably slide horizontally when the fixed state is released, thereby adjusting the spacing position between several groups.

[0058] During adjustment:

[0059] The screw on the base 1 is disengaged from the threaded connection or the fixed state, and then the base 1 and the components to be connected are directly pushed. Then it will slide on the surface of the sliding rod 7 through the formed through hole 5, so as to achieve stable horizontal sliding work. When it slides to the required position, it can stop moving, and then the base 1 can be locked and fixed by connecting parts such as screws;

[0060] Based on this technology, it is possible to adjust the spacing between several clamping devices when they are used simultaneously, so as to avoid the spacing being too close, and keep the position between several clamping devices unaffected.

[0061] In this embodiment, the clamping function of the buckle can be realized through the combined setting of the clamping mechanism 2 and the rotating mechanism 3. The operation is convenient and stable, and it is not easy to be damaged; when loosening, it is also relatively simple and convenient to operate, so as to improve the clamping efficiency of the buckle, effectively avoid problems such as loosening of the clamping device, easy to operate, and low cost. By pushing the connecting pipe 33 to rotate and the positioning pin 32 is fixed on the fixed clamp 22 for clamping, and the built-in spring 26 is used to assist in rotating and loosening, the required effect can be achieved. Moreover, while ensuring rotation, it can also be extended and adjusted to the required length position, so as to be adapted and installed to an external power device. During the color adjustment process, in cooperation with the locking mechanism 4, it can lock and position the position of the connecting pipe 33 and the extension rod 34 after adjusting the extension length, which can not only avoid displacement, but also ensure the subsequent connectivity and the stable effect of rotation.
