Description

Technical Field

[0001] This utility model belongs to the technical field of testing equipment, specifically relating to a rapid positioning device for multi-station testing samples. Background Technology

[0002] Multi-station rapid sample positioning devices are core auxiliary equipment in industrial batch testing scenarios. Through multi-station layout and precise positioning structure, they enable the simultaneous placement, positioning, and testing of multiple samples, significantly improving testing efficiency. They are widely used in large-scale quality testing in industries such as electronic components, mechanical parts, and automotive parts. Their core advantage lies in integrating multi-station flow and positioning functions, reducing manual intervention, ensuring consistency in sample positioning across different batches and stations, and providing a foundation for accurate testing data. However, existing multi-station rapid sample positioning devices require manual adjustment of the sample position to align with the positioning mechanism during use, which is cumbersome and time-consuming, affecting the efficiency of batch testing. Furthermore, they lack an effective pre-positioning structure, and the sample is prone to displacement due to turntable rotation or slight collisions before final clamping, resulting in positioning deviation. Utility Model Content

[0003] The purpose of this invention is to provide a rapid positioning device for multi-station testing samples, in order to solve the problems mentioned in the background art. Existing rapid positioning devices for multi-station testing samples require manual adjustment of the alignment and positioning mechanism for sample placement, which is cumbersome and time-consuming, affecting the efficiency of batch testing. Furthermore, they lack an effective pre-positioning structure, and the sample is prone to displacement due to turntable rotation or slight collision before final clamping, resulting in positioning deviation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rapid sample positioning device, comprising a multi-station detection turntable and a hexagonal integrated base fixed at the center of its top end by multiple embedded screws. Positioning clamping mechanisms are fixed to the outer walls of all six sides of the hexagonal integrated base. Multiple sample positioning placement plates are equidistantly arranged on the outer wall of the top end of the multi-station detection turntable near its edge, and a positioning clamping stop is welded to one end of the plate located at the edge of the turntable. The multiple positioning clamping mechanisms and the multiple positioning clamping stops are arranged in a one-to-one correspondence, and each of the multiple positioning clamping stops is equipped with an auxiliary positioning clamping device.

[0005] Preferably, the auxiliary positioning clamping device includes a strip-shaped fixing plate, a metal base block A, and a metal base block B. Taking the auxiliary positioning clamping device located at the rear end of the top of the multi-station detection turntable as an example, the strip-shaped fixing plate is fixed to the outer wall of the rear end of the positioning clamping stop at this position by multiple screws. Metal base blocks A and B are welded to the left and right ends of the strip-shaped fixing plate, respectively, and both extend longitudinally backward.

[0006] Preferably, the auxiliary positioning and clamping device further includes an auxiliary clamping plate A, an auxiliary clamping plate B, and prism-shaped connecting rods. Square holes are opened inside the rear center of both metal base blocks A and B, and prism-shaped connecting rods are inserted into both square holes. Both prism-shaped connecting rods face the longitudinal center line of the sample positioning plate, and auxiliary clamping plate A and auxiliary clamping plate B are welded to one end of each rod facing the longitudinal center line. Auxiliary clamping plate A and auxiliary clamping plate B are arranged symmetrically on the left and right.

[0007] Preferably, the auxiliary clamping plate A and the auxiliary clamping plate B are both located above the sample positioning plate. The prism-type connecting rod can move left and right in the square hole, and simultaneously drive the auxiliary clamping plate A and the auxiliary clamping plate B to move left and right. The square hole, through its square structure, can prevent the prism-type connecting rod from rotating during movement.

[0008] Preferably, the auxiliary positioning and clamping device further includes auxiliary clamping springs and arc-shaped insertion guides. Arc-shaped insertion guides are welded to the top of both auxiliary clamping plate A and auxiliary clamping plate B, and the tops of the two arc-shaped insertion guides extend to the left and right respectively. Auxiliary clamping springs are provided between auxiliary clamping plate A and metal base block A, and between auxiliary clamping plate B and metal base block B, and the auxiliary clamping springs are respectively sleeved on the outside of the two prism-shaped connecting rods.

[0009] Preferably, the auxiliary positioning and clamping device further includes a hand-tightening locking screw and an initial distance limiting sleeve. The two prism-shaped connecting rods are each fitted with an initial distance limiting sleeve at the end away from the sample positioning plate. The top of the initial distance limiting sleeve is threaded with a hand-tightening locking screw through a screw hole. The initial distance limiting sleeve can move left and right outside the prism-shaped connecting rod.

[0010] Preferably, after the initial distance limiting sleeve changes the distance outside the prism-type connecting rod and is locked in position by a hand-tightening locking screw, the initial clamping distance between the auxiliary clamping plate A and the auxiliary clamping plate B can be changed, so that samples of different sizes can be inserted between the auxiliary clamping plate A and the auxiliary clamping plate B.

[0011] Preferably, the sample positioning plate has limit baffles welded to both sides of the top center, and the sample needs to be placed on the sample positioning plate in the area between the two limit baffles. The sample positioning plate has screw fixing plates welded to one end facing the center of the multi-station detection turntable and the other end away from its center. The screw fixing plates are fixedly connected to the multi-station detection turntable by multiple screws. The auxiliary clamping plate A and the auxiliary clamping plate B are both located above the limit baffles to ensure that the auxiliary clamping plate A and the auxiliary clamping plate B do not contact the top of the limit baffles when they move.

[0012] Preferably, the positioning and clamping mechanism includes a positioning and clamping cylinder, a positioning clamping plate, a screw fixing plate, and a dual-axis cylinder shaft. The positioning and clamping cylinder is fixedly connected to the hexagonal integrated seat through a flange and screws. The cylinder has a dual-axis cylinder shaft inside through a plunger. The end of the dual-axis cylinder shaft facing the positioning and clamping stop is welded with a screw fixing plate, which is fixed to the positioning clamping plate by multiple screws. When the dual-axis cylinder shaft pushes the positioning clamping plate to move towards the positioning and clamping stop, the sample can be directly positioned and clamped between the two.

[0013] Compared with the prior art, this utility model provides a rapid positioning device for multi-station testing samples, which has the following beneficial effects: This invention adds a novel auxiliary positioning and clamping device to each positioning and clamping stop. When the sample to be tested is placed on the sample positioning plate and is ready to be positioned and clamped by the positioning and clamping mechanism on the positioning and clamping stop, the sample to be tested needs to be quickly inserted from top to bottom between the auxiliary positioning and clamping devices. This device can realize the pre-positioning and auxiliary clamping of the sample, improve the positioning efficiency and clamping stability, adapt to different specifications of samples, and form a double fixation with the positioning and clamping mechanism to ensure the detection accuracy. The arc-shaped insertion guide plates of the auxiliary positioning and clamping device are distributed outwards to the left and right. When the sample falls, they provide smooth guidance, allowing the sample to automatically slide between the two auxiliary clamping plates without manual adjustment. The prism-type connecting rod moves linearly within the square holes of metal base blocks A and B, forming a continuous clamping force in conjunction with the auxiliary clamping springs on the outer sleeve. This ensures that the sample is stably clamped from the outset, preventing it from tipping over, slipping, or swaying before the positioning and clamping cylinder actuates. This provides a reliable basis for the next step of precise positioning. Furthermore, the device also features an adjustable spacing adjustment mechanism consisting of an initial distance limit sleeve and a hand-tightening locking screw. This allows the operator to quickly adjust the initial distance between auxiliary clamping plates A and B according to the sample size, expanding the device's adaptability to different sample sizes and improving its versatility.

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1-5 The device illustrates a rapid sample positioning device for multi-station testing. The device uses a multi-station testing turntable 1 as its core support and circulation structure. The turntable enables continuous distribution, positioning, and testing of samples across multiple stations. A hexagonal integrated base 3 is fixedly connected to the center of the top of the multi-station testing turntable 1 via multiple embedded screws. Each of the six sides of the hexagonal integrated base 3 is equipped with an independent positioning and clamping mechanism 2, meeting the process requirements for simultaneous testing of samples at six stations. Multiple sample positioning plates 7 are equidistantly arranged on the outer wall of the top of the multi-station testing turntable 1 near its edge. Each positioning plate corresponds one-to-one with a positioning and clamping mechanism 2, forming an independent positioning and testing unit. To ensure assembly reliability and long-term operational stability, screw fixing plates 5 are welded to both the end of the sample positioning plate 7 facing the center of the turntable and the end away from the center. These screws securely connect the plate to the turntable, preventing loosening during high-speed operation or frequent movements.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, limit baffles 8 are welded to both sides of the top center of the sample positioning plate 7. The sample needs to be placed between the two limit baffles 8, which can limit the lateral displacement of the sample from the left and right directions, providing a basic reference for subsequent positioning and clamping. A limit clamping seat is welded to one end of the sample positioning plate 7 near the edge of the turntable. The positioning and clamping mechanism 2 consists of a positioning and clamping cylinder 9, a positioning clamping plate 10, a screw fixing piece 11, and a dual-axis cylinder shaft 12. The positioning and clamping cylinder 9 is fixed to the hexagonal integrated base 3 by a flange and screws. It has a reciprocating dual-axis cylinder shaft 12 inside. The screw fixing piece 11 is welded to one end of the dual-axis cylinder shaft 12 facing the positioning and clamping seat 6, and is fastened to the positioning clamping plate 10 by screws. When the sample is placed in the predetermined position, the positioning and clamping cylinder 9 extends the dual-axis cylinder shaft 12, driving the positioning clamping plate 10 to move towards the positioning and clamping seat 6, so as to achieve the final clamping and positioning of the sample, so that it remains stable in position during the detection process and is not affected by vibration and external force.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, in order to improve sample placement efficiency and enhance pre-positioning effect, auxiliary positioning clamping devices 4 are set on multiple positioning clamping blocks 6. Taking the auxiliary device at the rear end of the top of the multi-station detection turntable 1 as an example, the device consists of a strip-shaped fixing plate 13, a metal base block A14, a metal base block B21, a prism-type connecting rod 20, and an auxiliary clamping plate. The strip-shaped fixing plate 13 is fixed to the rear outer wall of the positioning clamping block 6 by multiple screws. The longitudinally extended metal base blocks A14 and B21 are welded to its left and right sides respectively. Both of them have square holes on their rear center. The prism-type connecting rod 20 is inserted into the square holes and can slide freely in the left and right directions. The square structure can effectively limit its rotation and keep the auxiliary clamping direction stable. The auxiliary clamping plate A18 and the auxiliary clamping plate B19 are welded to the end of the prism-type connecting rod 20 facing the sample positioning plate 7 respectively. The two are arranged symmetrically on the left and right, located above the sample positioning plate 7 and higher than the limiting block 8 to avoid interference during movement.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, arc-shaped insertion guide plates 17 are welded to the top of both auxiliary clamping plate A18 and auxiliary clamping plate B19. The guide plates extend to the left and right in an arc shape. When the sample is put in from top to bottom, it can be guided into the clamping area by the arc-shaped guide surface without manual adjustment of direction, thereby achieving rapid pre-positioning. Auxiliary clamping springs 16 are configured between auxiliary clamping plate A18 and metal base block A14, and between auxiliary clamping plate B19 and metal base block B21, and are sleeved on the outside of prism-type connecting rod 20. The continuous elastic force of the spring keeps the two auxiliary clamping plates close to the center, which can form a preliminary clamping of the sample and prevent the sample from shifting or tilting before the final clamping action.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, to accommodate samples of different specifications, an initial distance limiting sleeve 22 is fitted on the outside of the end of the two prism-shaped connecting rods 20 away from the sample positioning plate 7. The top of the limiting sleeve has a screw hole, and the internal thread is connected to a hand-tightening locking screw 15. The limiting sleeve can slide left and right along the prism-shaped connecting rods 20. By adjusting its position and tightening the locking screw, the initial clamping distance between the auxiliary clamping plate A18 and the auxiliary clamping plate B19 can be changed, making the device compatible with samples of various sizes. The pre-clamping provided by the auxiliary positioning clamping device 4 and the final clamping of the positioning clamping mechanism 2 form a dual positioning structure, which significantly improves positioning efficiency and clamping stability, and ensures accuracy, consistency and reliability in the multi-station batch testing process.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
