[0012] Furthermore, a mounting base is fixedly installed on the outer wall of the non-drive end of the bidirectional electric actuator, and the mounting base is fixedly connected to the middle position of the inner wall of the rectangular groove.
[0013] Through the above technical solution, the driving component can realize the connection and spacing adjustment of the two sets of clamping components.
[0014] Furthermore, an auxiliary rod is fixedly connected to the center of the rear end of each of the two fixed arms. Both auxiliary rods are located on the rear side of the vertical plate, and a roller is fixedly connected to the end of each auxiliary rod away from the fixed arm.
[0015] Furthermore, the wheel body of both rollers rolls in contact with the outer rear surface of the vertical plate, and a slide rail ring is embedded in the outer wall of the middle part of the wheel body of both rollers. The wheel body of both rollers is slidably sleeved with a semi-circular slide rail through the slide rail ring, and the semi-circular slide rail is fixedly connected to the rear end face of the vertical plate.
[0016] Through the above technical solution, the semi-circular slide rail achieves the function of limiting the sliding movement of the rolling wheel.
[0017] In summary, this application includes the following beneficial technical effects:
[0018] This application, through the base and vertical plate, facilitates the main support of the structure above it. In conjunction with the two sets of clamping components symmetrically arranged on both sides of the front of the vertical plate, and the driving components arranged on the same side of the two sets of clamping components, it can achieve fast and stable clamping of cylindrical metal workpieces, and is applicable to metal workpieces of different lengths and diameters.

[0029] This application discloses a fixture for fixing a cylindrical metal workpiece. Please refer to [link / reference]. Figures 1 to 4The system includes a base 1, a vertical plate 2 fixedly connected to the top of the base 1, and support legs fixedly connected to the four corners of the bottom of the base 1. Two sets of clamping components are symmetrically arranged on both sides in front of the vertical plate 2. Both sets of clamping components are located above the base 1, and a driving component is provided on the same side of the two clamping components.
[0030] The clamping component includes a clamping plate 3. An extension seat 4 is fixedly connected to one side of the bottom end of the clamping plate 3. Notches 5 are embedded on both sides of the middle of the extension seat 4. A positioning frame 6 is provided above both notches 5. The outer ends of the positioning frame 6 are movably inserted into and adapted to the inner walls of the two notches 5. The positioning frame 6 has an inverted "V" shaped frame structure, and an anti-slip rubber pad is fixedly installed on the inner side wall of the lower end of the positioning frame 6. An adjustment groove 7 is provided through the middle of the clamping plate 3, and a threaded rod 8 is rotatably installed in the middle of the clamping plate 3 through the adjustment groove 7. A motor 9 is connected to the top and is fixedly installed on the top plane of the clamping plate 3. A sliding block 10 is screwed onto the outer wall of the threaded rod 8. The sliding block 10 is located inside the adjustment groove 7, and a fixed shaft 11 is fixedly connected to one end face of the sliding block 10. The end of the fixed shaft 11 facing away from the sliding block 10 is fixedly connected to one side of the upper end of the positioning frame 6. Slide rails 12 are fixedly connected to both sides of the middle part of the sliding block 10. Slide rail grooves 13 are slidably sleeved on the opposite sides of the two slide rails 12, and the two slide rail grooves 13 are slidably sleeved on both sides of the inner wall of the adjustment groove 7.
[0031] The driving component includes fixed arms 14 that are fixedly connected to the same side of the two clamping plates 3 respectively. The outer walls of the rear ends of the two fixed arms 14 are slidably fitted with rectangular grooves 15. The rectangular grooves 15 are opened through the inner cavity of the vertical plate 2. A bidirectional electric actuator 16 is provided on the inner side of the middle of the rectangular grooves 15. The two driving ends of the bidirectional electric actuator 16 are fixedly connected to the two fixed arms 14 respectively. A mounting base is fixedly fitted on the outer wall of the non-driving end in the middle of the bidirectional electric actuator 16. The mounting base is fixedly connected to the middle position of the inner wall of the rectangular grooves 15. The mounting base can realize the stable connection of the working position of the bidirectional electric actuator 16.
[0032] Auxiliary rods 17 are fixedly connected to the center of the rear end of each of the two fixed arms 14. Both auxiliary rods 17 are located on the rear side of the vertical plate 2, and rolling wheels 18 are fixedly connected to the ends of the two auxiliary rods 17 away from the fixed arms 14. The wheel bodies of the two rolling wheels 18 roll in contact with the outer surface of the rear end of the vertical plate 2. Slide rail rings are embedded in the outer wall of the middle part of the wheel body of the two rolling wheels 18, and the wheel bodies of the two rolling wheels 18 are slidably sleeved with a semi-circular slide rail 19 through the slide rail rings. The semi-circular slide rail 19 is fixedly connected to the rear end face of the vertical plate 2. The auxiliary rods 17, rolling wheels 18, and semi-circular slide rail 19 on both sides can improve the sliding stability of the two fixed arms 14, and indirectly improve the stability of the working position of the clamping plates 3 on both sides.
[0033] The implementation principle of this embodiment is as follows: When in use, the cylindrical metal workpiece is placed between the two clamping plates 3. Under the synchronous drive of the two fixed arms 14 by the bidirectional electric push rod 16, the two clamping plates 3 are indirectly moved relative to each other and contact the two ends of the metal workpiece, thereby achieving the effect of applying to metal workpieces of different lengths. Then, the two ends of the metal workpiece are respectively placed on the top middle position of the two extension seats 4. Under the drive state of the threaded rod 8 by the motor 9 on each side and the vertical movement limit state of the sliding block 10 by the slide rails 12 and slide rail grooves 13 on both sides, the sliding block 10 is indirectly driven by the fixed shaft 11 to perform vertical sliding movement during the height adjustment process inside the adjustment groove 7. The lower inner wall of the positioning frame 6 achieves contact and stable clamping of the end of the metal workpiece. The structural design of the inner end of the positioning frame 6 can also facilitate the clamping effect of metal workpieces of different diameters (depending on the diameter of different metal workpieces, if necessary, the lower two sides of the positioning frame 6 will be inserted into the notch grooves 5 on both sides of the extension seat 4).
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
