DETAILED DESCRIPTION
[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Example 1
[0029] like Figure 1 to Figure 4 As shown, this embodiment proposes a hydraulic press clamping and positioning assembly, including a hydraulic press base 1, a motor 2 is fixedly connected to the outer side of the hydraulic press base 1, and the motor 2 is fixedly connected to a threaded rod 3 through an output shaft. The threads on both sides of the outer side of the threaded rod 3 are in opposite directions, and threaded blocks 4 are provided on both sides of the outer side of the threaded rod 3. The two threaded blocks 4 are both connected to the threaded rod 3 through threads, and the two threaded blocks 4 are both fixedly connected to the outer sides of the limit rods 5. One end of the two limit rods 5 is fixedly connected to a moving shell 6, and both sides of the inner sides of the two moving shells 6 are provided with empty grooves 7, and the two empty grooves 7 are fixedly connected with springs 8, and the outer ends of the two springs 8 are fixedly connected with moving columns 9, and one side of the two moving columns 9 is fixedly connected with a clamping plate 10, and one side of the clamping plate 10 is fixedly connected with an anti-skid layer 11, and the outer side of the anti-skid layer 11 is fixedly connected with a guide rod 12, and one side of the moving shell 6 is fixedly connected with two fixed rods 13, and a switch 14 is fixedly connected between the two fixed rods 13, and a display light 15 is fixedly connected to one side of the switch 14, and the switch 14 and the display light 15 are electrically connected.
[0030] In this embodiment, the threaded rod 3 extends into the interior of the hydraulic press base 1 and is connected to the hydraulic press base 1 via a bearing. The two limit rods 5 are arranged in a zigzag shape, so that the threaded rod 3 can be supported and rotated.
[0031] In this embodiment, the two limit rods 5 are extended to the outside of the hydraulic press base 1, and the two empty grooves 7 and the springs 8 are symmetrically distributed, so that the limit rods 5 can move.
[0032] In this embodiment, the two movable columns 9 extend to the outside of the two empty slots 7 respectively, and the outer surfaces of the two movable columns 9 are in contact with the inside of the two empty slots 7 respectively, so that the movable columns 9 can move.
[0033] In this embodiment, the guide rod 12 extends to the inside of the moving shell 6 and contacts the moving shell 6 , and the two fixing rods 13 are both arranged in an L shape, so that the guide rod 12 can move inside the moving shell 6 .
[0034] In this embodiment, the bottoms of the two moving shells 6 are in contact with the top of the hydraulic press base 1, and the bottoms of the two clamping plates 10 are also in contact with the top of the hydraulic press base 1, so that the clamping plates 10 can clamp the material.
[0035] During use, when it is necessary to clamp the material, the staff first needs to turn on the motor 2. After the motor 2 is turned on, it will synchronously drive the threaded rod 3 to rotate. During the rotation process, the threaded rod 3 will synchronously drive the threaded blocks 4 on both sides to move toward the middle. During the movement process, the threaded blocks 4 will synchronously drive the limit rod 5 to move. During the movement process, the limit rod 5 will synchronously drive the moving shell 6 to move. During the movement process, the moving shell 6 will synchronously drive the spring 8, the moving column 9 and the clamping plate 10 to move. When the outer surface of the material contacts the anti-slip layer 11, the anti-slip effect will be achieved. Then the limit rod 5 will move relative to the material. Since the limit rod 5 will drive the moving shell 6 to move continuously toward the middle, the moving shell 6 will drive the spring 8 to compress and the moving column 9 will enter the inside of the empty slot 7 during this process. At the same time, the guide rod 12 will gradually approach the switch 14. When the two are against each other, the display light 15 will flash, so that it can be judged by the light whether the material is clamped, to prevent the clamping assembly from being damaged due to loose or tight contact when it is unknown whether the clamp is in place.
[0036] Example 2
[0037] like Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the tops of the two clamping plates 10 are both provided with sliding grooves 16, and the two sliding grooves 16 are both provided with sliding blocks 17 inside, which can facilitate the sliding of the sliding blocks 17.
[0038] In this embodiment, the outer surfaces of the two sliding blocks 17 are in contact with the inside of the two sliding grooves 16 respectively, and the tops of the two sliding blocks 17 are fixedly connected with connecting blocks 18 to facilitate the movement of the connecting blocks 18.
[0039] In this embodiment, cleaning rods 19 are fixedly connected to the tops of the two connection blocks 18, and the two cleaning rods 19 are both arranged in an inverted L shape.
[0040] In this embodiment, the outer surfaces of the two cleaning rods 19 are in contact with the outside of the two clamping plates 10 respectively, and the bottom of the cleaning rod 19 does not contact the top of the hydraulic press base 1, which makes it easy for the cleaning rod 19 to clean the anti-slip layer 11 after rotation.
[0041] During use, when the anti-skid layer 11 needs to be cleaned, the staff first needs to lift the cleaning rod 19. During the lifting process, the cleaning rod 19 will simultaneously drive the connecting block 18 and the sliding block 17 to be lifted. Then the staff turns the long side of the cleaning rod 19 to the direction of the anti-skid layer 11. After that, the staff resets the sliding block 17 to the inside of the sliding groove 16, and then slides the cleaning rod 19. During this process, the cleaning rod 19 will simultaneously drive the connecting block 18 and the sliding block 17 to move, and can scrape and clean the impurities adhered to the outer surface of the anti-skid layer 11 to prevent the occurrence of poor anti-skid effect due to excessive surface attachments.
[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
