Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically an adaptive clamping device for precision parts of medical testing instruments. Background Technology

[0002] An adaptive clamping device is a device that can automatically adjust the clamping force and clamping method according to the shape, size and other characteristics of precision parts. In the manufacturing process of medical testing instruments, due to the high precision requirements of the parts, such as various high-precision sensor parts and small optical lens clamps, traditional fixed clamping methods may cause the fragile instrument parts to break due to excessive clamping force, and cannot guarantee the accuracy of clamping. At the same time, it is also impossible to adjust according to the shape and size of the instrument parts.

[0003] To address this, we propose an adaptive clamping device for precision parts of medical testing instruments. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive clamping device for precision parts of medical testing instruments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive clamping device for precision parts of medical testing instruments, comprising a base and clamping claws, with support plates installed on both the left and right ends of the base, a first motor mounted on the left side of the support plate, a screw connected to the drive end of the first motor, push rods sleeved on both the left and right ends of the screw, the push rods being connected to a connecting plate via a lower telescopic rod, and a fixed seat and a support rod provided at the lower part of the connecting plate.

[0006] As a further embodiment of this utility model: a controller is installed on the left side inside the base, the first motor is connected to the support plate through a motor mounting base, and both are installed below the base. Screws are symmetrically connected to the front and rear inner sides of the support plate, and the push rod is aligned and connected to the screw thread through the internal thread groove.

[0007] As a further embodiment of this utility model: the telescopic rod is vertically installed at the lower end of the base body via an upper push rod. The fixed base is located at the center directly below the connecting plate, and a groove is provided on the inner side of the fixed base. A rotating shaft is installed inside the groove. The rotating shaft is fixed to the inner wall of the fixed base via two fixing rings on both sides. A cylinder is installed below the rotating shaft. The cylinder is fixed to the side of the support rod via connecting blocks on the left and right sides. Connecting blocks are installed on both sides of the support rod, and the connecting blocks are fixed to the support rod with bolts. The support rod is movably installed between the connecting blocks and the fixed base.

[0008] As a further embodiment of this utility model: an angle adjustment assembly is installed on the inner side below the support rod. The angle adjustment assembly includes a second motor, a first gear, a second gear, a rotating ring, a connecting rod, a connecting rod, and a connecting elbow. The second motor is located on the bottom surface of the support rod. The drive end of the second motor is connected to the first gear. The first gear meshes with the second gear above it through the teeth on its outer diameter. The rotating ring is installed on the inner ring of the second gear. The connecting rod is symmetrically installed on the left and right sides of the rotating ring, and the connecting rod is fixed to the rotating ring by bolts. The rotating ring is connected to the connecting elbow through the connecting rod. The connecting elbow is in the shape of a semi-circular ring.

[0009] As a further embodiment of this utility model: the support rod is connected to the clamping force adjustment assembly via a side angle adjustment assembly. The clamping force adjustment assembly includes a fixed plate, a third motor, a sliding rod, and a slider. The fixed plate is located on the connecting elbow side. Connecting rods are installed on both the left and right ends below the fixed plate and are fixed together by bolts. The third motor is installed on the front of the fixed plate. A sliding groove is provided on the inner side of the fixed plate. The sliding rod is connected to the drive end of the third motor. The sliders are symmetrically installed on the left and right ends of the outer wall of the sliding rod.

[0010] As a further embodiment of this utility model: a clamping claw is mounted on the inner side of the slider, a tactile sensor is mounted on the inner ring of the clamping claw, and an anti-slip structure is provided at the front end of the clamping claw.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. In this utility model, the rotating ring at the inner ring of the second gear rotates together with the second gear, and the connecting rods fixed on the left and right sides of the rotating ring also make circular motion. At this time, the connecting elbow is transmitted by the motion of the connecting rod, which can push the fixed plate and the clamping claw to move. Therefore, through the continuous rotation of the rotating ring, the clamping claw can achieve 360° all-round rotation adjustment, which greatly improves the angle coverage of the clamping claw and can flexibly adapt to the operation requirements of various directions. At the same time, through the pushing action of the connecting elbow, the clamping claw can also be tilted at different angles to better fit the parts and achieve tight and stable clamping.

[0013] 2. This utility model uses a third motor to drive a sliding rod to move the slider to a suitable position. The sliding of the slider adjusts the position between the clamping claws on the left and right sides of the fixed plate, allowing them to move to a suitable position and apply sufficient clamping force. This achieves the adjustment of the clamping force on the appliance parts, effectively avoiding the risk of fragile appliance parts breaking due to excessive clamping force, and ensuring that the appliance parts will not shift or loosen during processing, inspection, etc.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 5This utility model discloses an adaptive clamping device for precision parts of medical testing instruments, comprising a base 1 and clamping claws 12. Support plates 2 are installed on both the left and right ends of the base 1. A first motor 3 is mounted on the left side of the support plate 2. The drive end of the first motor 3 is connected to a screw 4. Push rods 5 are sleeved on both the left and right ends of the screw 4. The first motor 3 drives the push rods 5 to move on the screw 4, causing the push rods 5 on both sides to move closer or further apart. Therefore, by moving the push rods 5, the position of the clamping claws 12 on both sides is adjusted, so that the clamping claws 12 can be adjusted according to the size of the instrument parts. The push rods 5 are connected to the connecting plate 7 through the lower telescopic rod 6. The height of the lower part is adjusted by the extension and retraction of the telescopic rod 6, so that it can adapt to the usage requirements of different heights. A fixed seat 8 and a support rod 9 are provided at the lower part of the connecting plate 7.

[0024] In Embodiment 1, the telescopic rod 6 is vertically installed at the lower end of the base 1 via the upper push rod 5. The fixed base 8 is located at the center directly below the connecting plate 7, and a groove is provided on the inner side of the fixed base 8. A rotating shaft 801 is installed inside the groove. The rotating shaft 801 is fixed to the inner wall of the fixed base 8 via two fixing rings. A cylinder 802 is installed below the rotating shaft 801. The cylinder 802 is fixed to the side of the support rod 9 via connecting blocks on the left and right sides. Connecting blocks are installed on both the left and right sides of the support rod 9, and the connecting blocks are fixed to the support rod 9 by bolts. The support rod 9 is movably installed between the connecting blocks and the fixed base 8.

[0025] Specifically, the height of the lower component is adjusted by extending and retracting the telescopic rod 6 to adapt to different height requirements. The cylinder 802 pushes the rotating shaft 801 to rotate within the groove of the fixed seat 8. The rotation of the rotating shaft 801 causes the support rod 9 to move vertically upward or downward. As a result, the clamping claw 12 installed on the inner side of the support rod 9 will change position synchronously with the up and down movement of the support rod 9. Therefore, by pushing the cylinder 802 to adjust the position of the clamping claw 12, the parts can be accurately gripped.

[0026] In embodiment 2, an angle adjustment assembly 10 is installed on the inner side below the support rod 9. The angle adjustment assembly 10 includes a second motor 1001, a first gear 1002, a second gear 1003, a rotating ring 1004, a connecting rod 1005, a connecting rod 1006, and a connecting elbow 1007. The second motor 1001 is located on the bottom surface of the support rod 9. The driving end of the second motor 1001 is connected to the first gear 1002. The first gear 1002 meshes with the second gear 1003 above it through the teeth on its outer diameter. The rotating ring 1004 is installed on the inner ring of the second gear 1003. The connecting rod 1005 is symmetrically installed on the left and right sides of the rotating ring 1004, and the connecting rod 1005 is fixed to the rotating ring 1004 by bolts. The rotating ring 1004 is connected to the connecting elbow 1007 through the connecting rod 1006. The connecting elbow 1007 is in the shape of a semi-circular ring.

[0027] Specifically, the second motor 1001 is started, driving the first gear 1002 to rotate. Since the first gear 1002 meshes with the second gear 1003, the rotational motion of the first gear 1002 is transmitted to the second gear 1003, causing the second gear 1003 to rotate around its axis. The rotating ring 1004, which is mounted on the inner ring of the second gear 1003, will rotate together with the second gear 1003. The connecting rods 1005, which are fixed on the left and right sides of the rotating ring 1004, also make circular motion. At this time, the connecting elbow 1007 is transmitted by the motion of the connecting rod 1005, which can push the fixed plate 1101 to swing up and down. When pushing the fixed plate 1101, it drives the clamping claw 12 to move. Therefore, through the continuous rotation of the rotating ring 1004, the clamping claw 12 can achieve 360° all-round rotation adjustment. At the same time, through the pushing action of the connecting elbow 1007, the clamping claw 12 can also be tilted at different angles.

[0028] In embodiment 3, the support rod 9 is connected to the clamping force adjustment assembly 11 via a side angle adjustment assembly 10. The clamping force adjustment assembly 11 includes a fixed plate 1101, a third motor 1102, a slide rod 1103, and a slider 1104. The fixed plate 1101 is located on one side of the connecting elbow 1007. Connecting rods 1005 are installed on both the left and right ends below the fixed plate 1101 and are fixed together by bolts. The third motor 1102 is installed on the front of the fixed plate 1101. A sliding groove is opened on the inner side of the fixed plate 1101. The slide rod 1103 is connected to the drive end of the third motor 1102. The slider 1104 is symmetrically installed on the left and right ends of the outer wall of the slide rod 1103.

[0029] Specifically, the third motor 1102 drives the slide bar 1103 to move. The sliders 1104 at both ends of the outer wall of the slide bar 1103 slide in the groove on the inner side of the fixed plate 1101. By sliding the sliders 1104, the position between the clamping claws 12 on the left and right sides of the fixed plate 1101 is adjusted so that they move to a suitable position and can apply sufficient clamping force, thereby realizing the adjustment of the clamping force on the tool parts.

[0030] In embodiment four, a clamping claw 12 is mounted on the inner side of the slider 1104, a tactile sensor 1201 is mounted on the inner ring of the clamping claw 12, and an anti-slip structure is provided at the front end of the clamping claw 12.

[0031] Specifically, when the clamping claw 12 begins to clamp the part, the tactile sensor 1201 can sense the contact force and contact state between the clamping claw 12 and the precision part of the medical testing instrument in real time, thereby accurately measuring the pressure at each position and different structural shapes, and transmitting the detected signals. The anti-slip structure enables the clamping claw 12 to firmly clamp the part.

[0032] Working principle:

[0033] First, the first motor 3 drives the push rod 5 to move on the screw 4, causing the two push rods 5 to move closer or further apart. Therefore, the movement of the push rods 5 adjusts the position of the clamping claws 12 on both sides, allowing the clamping claws 12 to be adjusted according to the size of the tool parts. When clamping the tool parts, the height of the lower component is adjusted by the extension and retraction of the telescopic rod 6, adapting to different height requirements. The cylinder 802 pushes the rotating shaft 801 to rotate within the groove of the fixed seat 8. The rotation of the rotating shaft 801 causes the support rod 9 to move vertically upwards or downwards, thus causing the clamping claws 12 installed inside the support rod 9 to move synchronously with the up-and-down movement of the support rod 9. The position of the clamping claw 12 is adjusted by pushing the cylinder 802 to ensure that the part can be accurately gripped. At the same time, the tactile sensor 1201 installed in the clamping claw 12 detects the shape of the tool part. When the surface of the tool part is detected to have curvature or tilt angle, the signal detected by the tactile sensor is transmitted to the controller 101. At this time, the controller 101 drives the second motor 1001 or the third motor 1102 and the first motor 3 according to the received signal, so that the clamping claw 12 can clamp according to the shape and size of the tool part, and adjust the clamping force, angle or position of the clamping claw 12 to achieve the function of adaptive clamping. At this point, the entire workflow is completed.
