Description

Technical Field

[0001] The utility model relates to a clamping carrier with a positioning function. Background Art

[0002] With the development of science and technology, the assembly of medical accessories has now achieved automation, and medical accessories are all assembled on an assembly machine. During assembly, generally, the accessories are placed on a carrier, and the carrier can move to each assembly station on the assembly machine frame to realize the assembly of this accessory with other accessories, and finally form the required medical accessory. Assembly accuracy is one of the most important indicators of a medical accessory assembly machine. Therefore, it is necessary to accurately position the catheter for subsequent assembly or processing of the catheter.

[0003] However, currently, the catheter often needs to be first positioned and restricted by the lower pipe clamping piece below, and then the upper pipe clamping piece is driven to further restrict the catheter. Since the interval between adjacent catheters must be kept consistent, the catheter needs to be accurately placed in the groove of the pipe clamping piece, and the clamping accuracy requirement is relatively high. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and provide a clamping carrier with a positioning function. What this application solves is the problem that the clamping accuracy of the existing catheter is too high and it is not easy to place, realizing the direct clamping of the catheter and reducing the placement accuracy requirement of the catheter.

[0005] A clamping carrier with a positioning function includes a base. It is characterized in that the surface of the base is slidably connected with a floating plate through a second sliding component. A plurality of clamping mechanisms arranged side by side at intervals are installed on the floating plate, and the surface of the floating plate has a limiting part that can at least accommodate the sliding and limiting of a limiting mechanism.

[0006] The floating plate can move along its length direction on the base, and can be fixed and limited by the limiting mechanism during the movement. During this process, when it is necessary to fix the floating plate, the limiting mechanism rises to be inserted into the limiting part. When it is not necessary to fix the floating plate, the limiting mechanism descends to be separated from the limiting part. At this time, the floating plate can slide freely on the base. When the floating plate is fixed, the clamping position of the pipe clamping part can be fixed, playing a role of primary fixation, improving the accuracy after the clamping mechanism clamps the catheter, ensuring the stability of the catheter clamping position, improving the pipe clamping error of the equipment, ensuring that the clamping mechanism can directly clamp the catheter, and reducing the placement accuracy requirement of the catheter during the clamping process.

[0007] Furthermore, the clamping mechanism includes a first linkage and a second linkage. The lower surfaces of the first linkage and the second linkage are both provided with a first sliding component, and the first sliding component is slidably connected with a sliding mechanism installed along the length direction of the floating plate.

[0008] In this application, the clamping and loosening of the catheter are realized by the opposite or facing movement of the first linkage and the second linkage, and the structure is flexible and simple.

[0009] Furthermore, first clamping portions are provided at both ends of the first linkage, and a plurality of first clamping parts are provided on the first clamping portions. Second clamping portions are provided at both ends of the second linkage, and second clamping parts which open and close in adaptation to the first clamping parts are provided on the second clamping portions.

[0010] In this application, the first clamping part and the second clamping part cooperate to clamp or loosen the catheter. The plurality of first clamping portions and the plurality of second clamping portions can move simultaneously and can cooperate to clamp simultaneously, ensuring the consistency of the clamping action during the operation of the equipment, improving the operation efficiency of the equipment, and reducing the operation cost.

[0011] Furthermore, the first linkage and the second linkage are respectively driven by a driving mechanism. The first linkage and the second linkage have a first movement stroke of moving towards each other and a second movement stroke of moving away from each other.

[0012] In this application, the opposite sliding of the first linkage and the second linkage causes the first clamping part and the second clamping part to open, and at this time the catheter is not clamped. The facing sliding of the first linkage and the second linkage causes the first clamping part and the second clamping part to close, and at this time the catheter is clamped. The structure driving is simple and the adjustment is simple.

[0013] Furthermore, a detachable adjusting block is installed on the inner side wall of the limiting portion.

[0014] In this application, adjusting blocks of different specifications can be installed inside the limiting portion, so as to adjust the internal size of the limiting portion, and can better accommodate the up and down movement of different limiting mechanisms, ensure that the limiting mechanism can be completely inserted into the limiting portion, avoid the floating plate shaking after insertion, ensure the fixing effect after the limiting mechanism is inserted into the limiting portion, and has stronger adaptability.

[0015] Furthermore, a plurality of conveying devices are installed on the lower surface of the base.

[0016] In this application, the lower surface of the base is conveyed through the conveying device, the transmission is smoother, and the transmission structure is simple.

[0017] Furthermore, limiting members are installed at both ends of the base.

[0018] In this application, it is avoided that the floating plate moves beyond the stroke, ensuring the safety during the use of the equipment.

[0019] Furthermore, clamping openings and clamping protrusions which are mutually closed and inserted are respectively provided on the opposite surfaces of the first clamping part and the second clamping part. A clamping notch is provided on the clamping protrusion, and the clamping notch and the clamping opening are closed to form a clamping area.

[0020] In this application, after the clamping notch and the clamping opening are closed, the catheter is stably clamped.

[0021] Furthermore, the limiting mechanism is driven to move up and down by a driving device, and the driving device is fixedly arranged on the conveyor line.

[0022] Beneficial effects:

[0023] In this device, the driving device controls the limiting roller to rise, and the limiting roller is inserted and fixed with the limiting part, so as to fix the floating plate. Compared with the prior art, the clamping and positioning mechanism of the pipe clamping piece is cancelled, the time for secondary positioning of the catheter is eliminated, the equipment efficiency and the positioning accuracy of the carrier are improved, the direct clamping of the catheter by the first clamping part and the second clamping part is realized, and the placement accuracy requirement and the processing accuracy of the catheter are reduced.

[0036] Embodiment 1

[0037] As Figures 1 to 6As a specific embodiment of the utility model, a clamping carrier with a positioning function includes a limiting part 1, a limiting mechanism 2, a driving device 3, a floating plate 4, a base 5, a conveying device 6, an adjusting block 7, a clamping mechanism 8, a first clamping part 81, a first clamping part 82, a second clamping part 83, a second clamping part 84, a first linkage 85, a second linkage 86, a sliding mechanism 9, a clamping opening 10, a sliding component 1 11, a sliding component 2 12, a limiting part 13, and a clamping protrusion 14.

[0038] In this embodiment, a clamping carrier with a positioning function includes a base 5, a sliding assembly 12 installed along the length direction is provided on the upper surface of the base 5, a floating plate 4 is installed on the sliding assembly 12 to slide back and forth along the length direction of the base 5, a plurality of clamping mechanisms 8 arranged in parallel and spaced apart are installed on the floating plate 4, and a limiting portion 1 is provided on the surface of the floating plate 4 to accommodate at least one limiting mechanism 2 to slide back and forth up and down, and the limiting mechanism 2 is driven to move up and down by a driving device 3.

[0039] The floating plate 4 can move along its length on the base 5, and can be fixed and limited by the limiting mechanism 2 during the movement. During this process, when the floating plate 4 needs to be fixed, the limiting mechanism 2 rises to be plugged with the limiting part 1. When the floating plate 4 does not need to be fixed, the limiting mechanism 2 drops to be separated from the limiting part 1. At this time, the floating plate 4 can slide freely on the base 5. When the floating plate 4 is fixed, the clamping position of the pipe clamping part can be fixed, which plays a one-time fixing role, improves the accuracy of the clamping mechanism 8 after clamping the catheter, ensures the stability of the catheter clamping position, improves the equipment clamping error, ensures that the clamping mechanism 8 can directly clamp the catheter, and reduces the accuracy requirements for its placement during the catheter clamping process.

[0040] The clamping mechanism 8 includes a first linkage member 85 and a second linkage member 86. The lower surfaces of the first linkage member 85 and the second linkage member 86 are both provided with a sliding component 11. The sliding component 11 is slidably connected with the sliding mechanism 9 installed along the length direction of the floating plate 4. The first linkage member 85 and the second linkage member move in opposite or opposite directions to achieve clamping and loosening of the catheter. The structure is flexible and simple.

[0041] The first linkage member 85 has first clamping parts 81 at both ends, and the first clamping parts 81 have multiple first clamping parts 82. The second linkage member 86 has second clamping parts 84 at both ends, and the second clamping parts 84 have second clamping parts 83 that fit with the first clamping parts 82. The first clamping parts 82 and the second clamping parts 83 cooperate to clamp or loosen the catheter. The multiple first clamping parts 81 and the multiple second clamping parts 84 can move at the same time and can clamp at the same time, so as to ensure the consistency of the clamping action during the operation of the equipment, improve the operation efficiency of the equipment, and reduce the operation cost.

[0042] The first linkage 85 and the second linkage 86 are respectively driven by a driving mechanism. The first linkage 85 and the second linkage 86 have a first movement stroke of moving towards each other and a second movement stroke of moving away from each other. When the first linkage 85 and the second linkage 86 slide away from each other, the first clamping portion 82 and the second clamping portion 83 open, and at this time, the catheter is not clamped. When the first linkage 85 and the second linkage 86 slide towards each other, the first clamping portion 82 and the second clamping portion 83 close, and at this time, the catheter is clamped. The structure has simple driving and simple adjustment.

[0043] The driving devices 3 are respectively installed on the base 5 and are hydraulically driven, having the function of reciprocating telescopic driving. Driving the first linkage 85 and the second linkage 86 to move away from or towards each other realizes the opening or closing of the first clamping portion 82 and the second clamping portion 83, achieving the effects of clamping and releasing the catheter.

[0044] A detachable adjustment block 7 is installed on the inner side wall of the limiting portion 1. Different specifications of adjustment blocks 7 can be installed inside the limiting portion 1, thereby adjusting the internal size of the limiting portion 1, enabling better accommodation of the up and down movement of different limiting mechanisms 2, ensuring that the limiting mechanism 2 can be fully inserted into the limiting portion 1, avoiding the floating plate 4 from shaking after insertion, and ensuring the fixing effect after the limiting mechanism 2 is inserted into the limiting portion 1, with stronger adaptability.

[0045] A plurality of conveying devices 6 are installed on the lower surface of the base 5. The lower surface of the base 5 is conveyed through the conveying devices 6, and the transmission is smoother and the transmission structure is simple.

[0046] The limiting mechanism 2 adopts a limiting roller structure. Using limiting rollers in the limiting mechanism 2 can improve the smoothness during the insertion process of the limiting mechanism 2 into the limiting portion 1, reduce the friction between the limiting mechanism 2 and the inside of the limiting portion 1 during the up and down movement of the limiting mechanism 2, reduce the wear and loss during the positioning movement, and at the same time avoid the generation of positioning errors caused by wear after multiple uses, extending the service life and accuracy of the equipment structure.

[0047] Limiters 13 are installed at both ends of the base 5 to prevent the floating plate 4 from moving beyond the stroke and ensure the safety of the equipment during use.

[0048] Clamping openings 10 and clamping protrusions 14 that are mutually closed and inserted are respectively provided on the opposite surfaces of the first clamping portion 82 and the second clamping portion 83. The clamping protrusion 14 has a clamping notch, and the clamping notch and the clamping opening 10 are closed to form a clamping area. After the clamping notch and the clamping opening 10 are closed, the catheter is stably clamped.

[0049] Embodiment 2

[0050] The second driving method of the first linkage 85 and the second linkage 86 is a linkage structure. In the second embodiment, other structures are basically the same as those in the first embodiment. Connecting members are respectively connected to both ends of the first linkage 85 and the second linkage 86, and sliding rollers are installed at the free ends of the connecting members. The sliding rollers on the same side of the first linkage 85 and the second linkage 86 have a first state of abutting against each other and a second state of moving away from each other. A separating mechanism that can move up and down is provided between the sliding rollers on the same side. The two side walls of the separating structure have inclined surfaces that abut against the sliding rollers, and the sliding rollers roll on the inclined surfaces to achieve their separation or abutment, so as to close or open the first clamping part 82 and the second clamping part 83.

[0051] Embodiment Three

[0052] The second driving method of the second sliding assembly 12 and the floating plate 4 is a roller sliding structure. In the second embodiment, other structures are basically the same as those in the first embodiment. Only rollers and rolling tracks for guiding the rollers are provided on the opposite surfaces of the second sliding assembly 12 and the floating plate 4. The rollers rotate forward and backward in the rolling tracks, thereby driving the floating plate 4 to reciprocate.

[0053] The specific operation process in use is as follows:

[0054] When it is necessary to clamp the catheter, it is necessary to fix the floating plate 4 and determine the clamping position of the catheter. In this process, first, it is necessary to adjust the position of the adjusting block 7 in the limiting part 1 according to the diameter of the limiting roller, and adjust the space size of the limiting part 1 after installing the adjusting block 7 to just accommodate one or more limiting rollers to roll through after abutting. Finally, the limiting roller stops at the middle position of the limiting part 1, and the side wall of the limiting roller abuts against the inner side wall of the limiting part 1, achieving the function of fixing the floating plate 4. After the limiting roller is inserted into the limiting part 1, the floating plate 4 is fixed and does not move. Then, the position of the first linkage 85 and the second linkage 86 is adjusted to clamp or open the catheter. During the opening and closing process of the first linkage 85 and the second linkage 86, only the catheter needs to be clamped, and there is no need to adjust the clamping position of the catheter, reducing the clamping difficulty. At the same time, the clamping requirements of the equipment and the placement requirements of the catheter are reduced. When it is not necessary to fix the floating plate 4, the limiting roller is driven to descend, and the floating plate 4 can move freely when the limiting roller is separated from the limiting part 1.

[0055] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
