[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5An embodiment of this utility model provides a flexible positioning fixture platform, including a platform 1. Slide plates 4 are symmetrically arranged on both sides above the platform 1. A clamping component 2 is arranged above each slide plate 4. Transmission plates 5 are symmetrically fixedly installed at the front and rear ends of the two slide plates 4. A screw box 6 is fixedly installed below the platform 1. A reverse thread screw 19 is rotatably installed inside the screw box 6. Sliding blocks 20 are symmetrically slidably installed at both ends of the outer side of the reverse thread screw 19. One end of the transmission plate 5 passes through the inside of the screw box 6 and is fixedly connected to the sliding block 20.

[0025] In use, the sliding block 20 is driven by the reverse threaded screw 19 in the screw box 6, which in turn drives the clamping components 2 on the transmission plate 5 and the slide plate 4 to move towards or away from each other, realizing the flexibility of workpiece clamping. This design allows the distance between the two clamping components 2 to be adjusted according to the actual size and position requirements of the workpiece, and by being able to clamp and position the workpiece in the middle position of the fixture platform, it is convenient for workpiece positioning and increases practicality.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The clamping assembly 2 includes a base plate 8, a clamping box 9, and a side block 10. The base plate 8 is fixedly connected to the slide plate 4. The clamping box 9 and the side block 10 are both fixedly installed on the top of the base plate 8. The clamping box 9 has a cavity inside. A flexible clamping post 11 is provided on one side of the clamping box 9, and multiple flexible clamping posts 11 are provided. One end of each flexible clamping post 11 extends into the cavity of the clamping box 9. A sleeve 12 is provided along one side of the flexible clamping post 11 inside the cavity of the clamping box 9, and the sleeve 12 is fixedly connected to the flexible clamping post 11. A compression spring 13 is fixedly installed inside the sleeve 12, and one end of the compression spring 13 extends out of the inside of the sleeve 12 and is fixedly connected to the clamping box 9.

[0027] The multiple flexible clamping posts 11 inside the clamping box 9 can adaptively clamp according to the shape and size of different workpieces, realizing the flexible clamping capability of the workpiece and improving the accuracy and adaptability of clamping. At the same time, the combined use of the sleeve 12 and the compression spring 13 provides elasticity and buffering for the flexible clamping posts 11, effectively avoiding damage to the workpiece during the clamping process.

[0028] Please see Figure 5 The front end of the clamping box 9 is provided with a second handwheel 15, and the rear end of the second handwheel 15 is fixedly installed with a screw rod 1. One end of the screw rod 1 is threadedly connected to the clamping box 9 and extends into the cavity of the clamping box 9. The end of the screw rod 1 away from the second handwheel 15 is rotatably installed with a fastening push plate 14, which contacts the flexible clamping column 11.

[0029] Handwheel 2 15 drives the fastening push plate 14 to move via screw 1, contacting and applying pressure to the flexible clamping column 11, which can press and fix the flexible clamping column 11, fixing its position and preventing it from swaying left and right, thus increasing the stability of clamping the workpiece.

[0030] Please see Figure 1 and Figure 2 A track plate 3 is fixedly installed above the platform 1. The track plate 3 slides through the slide plate 4. A handwheel 3 16 is set above the side block 10. A screw 2 is fixedly installed below the handwheel 3 16. The lower end of the screw 2 is threadedly connected to the side block 10 and passes into the interior of the slide plate 4 to contact the track plate 3.

[0031] By rotating handwheel 316, screw 2 can be moved down and pressed tightly onto track plate 3, thereby fixing the position of edge block 10 and increasing the positional stability of clamping assembly 2.

[0032] Please see Figure 1 and Figure 3 The front and rear surfaces of the platform 1 are symmetrically provided with stabilizing grooves 18, and a stabilizing plate 17 is fixedly installed inside the transmission plate 5, with one end of the stabilizing plate 17 extending into the interior of the stabilizing groove 18.

[0033] The combined use of the stabilizing groove 18 and the stabilizing plate 17 effectively enhances the stability between the transmission plate 5 and the platform 1, prevents the transmission plate 5 from shaking and shifting during movement, and improves the overall stability and safety of the fixture platform.

[0034] Please see Figure 1 A handwheel 7 is provided on one side of the screw box 6. A transmission rod is fixedly installed on the side of the handwheel 7 facing the screw box 6, and one end of the transmission rod extends into the interior of the screw box 6 and is fixedly connected to the reverse thread screw 19.

[0035] The reverse threaded screw 19 is driven to rotate by manually rotating the handwheel 7, thereby enabling the slide plate 4 and the clamping assembly 2 to move towards or away from each other. The manual drive method is not only easy to operate and low in cost, but also enables stable adjustment of the position of the clamping assembly 2, improving the practicality and reliability of the fixture platform.

[0036] Working principle: During use, by manually rotating handwheel 17, the reverse thread screw 19 inside the screw box 6 is driven to rotate, causing the two sliding blocks 20 to slide inside the screw box 6. This, in turn, drives the clamping components 2 on the transmission plate 5 and the slide plate 4 to move closer to each other, thereby achieving workpiece clamping. The multiple flexible clamping columns 11 in the clamping components 2 can adaptively clamp according to the shape and size of different workpieces. The elasticity and buffering provided by the sleeve 12 and the compression spring 13 effectively avoid damage to the workpiece during clamping. At the same time, by adjusting the screw 1 through handwheel 2 15, the fastening push plate 14 is driven to press and fix the flexible clamping columns 11, increasing the stability of clamping the workpiece. In addition, handwheel 3 16 contacts the track plate 3 through screw 2, thereby fixing the position of the side block 10 and the clamping components 2, improving the stability of the fixture platform.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
