Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a fixing device for processing plastic products. Background Art

[0002] The Chinese patent with the authorization announcement number of "CN218838360U" and the name of "A clamping and positioning device for processing plastic products" includes a frame, a flipping mechanism is installed on one side of the frame, one end of the flipping mechanism is fixedly connected to a sleeve, a fixed disk is installed at the bottom of the sleeve, a rotating disk is installed at the top of the sleeve, a driving motor is fixedly connected to the bottom of the fixed disk, the output shaft of the driving motor passes through the sleeve and is connected to the rotating disk, a plurality of guide rails are radially installed on the top surface of the fixed disk, and claws are slidably connected in the guide rails, a sliding rod is installed through one end of the claw, an arc groove for sliding the sliding rod is opened on the top of the rotating disk, and a linear sliding groove for sliding the sliding rod is opened at the bottom of the fixed disk. The utility model drives the entire clamping device to flip through the flipping mechanism, which can not only use the multiple retracted claws to clamp and position the product from different directions outside, but also use the multiple opened pressure blocks to press against the inside of the product to open and clamp the product, and there are various ways to position the product.

[0003] The above-mentioned prior art positions the plastic product by abutting the inside of the plastic product with the clamping claws, but it is difficult to fix special-shaped plastic products whose side walls are at inconsistent distances from the center. The synchronous movement of the clamping claws makes the device only able to position circles or regular polygons, and cannot meet the needs of fixing special-shaped plastic products, and has poor adaptability. In addition, the device requires manual adjustment of the adjusting screw to clamp the plastic product, and the overall structure is also relatively complex, which is not convenient for operation and maintenance.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] See also Figure 1-7A fixing device for processing plastic products comprises a frame 1, the frame 1 is provided with a clamping mechanism, the clamping mechanism comprises a motor 5 fixedly mounted on the frame 1, a rotating plate 2 is fixedly connected to the output shaft of the motor 5, the rotating plate 2 is rotatably connected to the frame 1, an arc groove 21 is provided on the rotating plate 2, a placement plate 3 is provided on the upper side of the rotating plate 2, the placement plate 3 is fixedly connected to the frame 1, a plurality of accommodating grooves 31 are provided in the placement plate 3, a claw 4 is slidably connected in each of the accommodating grooves 31, a sliding rod 41 adapted to the arc groove 21 is fixedly provided on the claw 4, the sliding rod 41 passes through the placement plate 3 and is slidably connected to the arc groove 21, a spring 33 is also provided in the accommodating groove 31, and two ends of the spring 33 are respectively fixedly connected to the accommodating groove 31 and the claw 4. The motor 5 drives the rotating disk to rotate. The rotation of the rotating disk cooperates with the arc groove 21 and the sliding rod 41, so that the claws 4 move synchronously along the accommodating groove 31 on the placement plate 3. When the claws 4 abut against the plastic product, the spring 33 is deformed. Since the side walls of the plastic product are at different distances from the center, the claws 4 continue to move until each claw 4 abuts against the plastic product placed on the placement plate 3, thereby completing the clamping of the plastic product. In addition, the claws 4 of the device can clamp and fix the plastic product through the inner wall or outer wall of the plastic product. The structure is relatively simple, no flipping is required, and it is easy to operate and maintain.

[0028] In a further embodiment provided by the present invention, the claws 4 are distributed in a circular array in the placement plate 3 , so that the claws 4 can slide synchronously along the receiving grooves 31 on the placement plate 3 .

[0029] In a further embodiment provided by the utility model, the clamping claw 4 includes a clamping block 42, the clamping block 42 is fixedly connected to the end of the spring 33, an L rod 43 is also fixedly connected to the clamping block 42, the receiving slot 31 includes a first slot 311 and a second slot 312 that are interconnected, the clamping block 42 is slidably connected to the first slot 311, and the L rod 43 is slidably connected to the second slot 312. The size of the first slot 311 is larger than the second slot 312, so that the clamping block 42 can only slide in the first slot 311 to prevent the clamping claw 4 from sliding out of the receiving slot 31, that is, the first slot 311 serves to limit the position of the clamping claw 4.

[0030] In a further embodiment provided by the utility model, a protective column 32 is fixedly disposed in the first slot 311, and the spring 33 is passed through the outside of the protective column 32. When the claw 4 moves toward the center of the placement plate 3, the claw 4 abuts against the protective column 32 to prevent the spring 33 from being over-compressed and damaged.

[0031] In a further embodiment provided by the utility model, a cylindrical rod 44 is fixedly provided at the end of the L rod 43. Anti-skid pads are provided at the end of the L rod 43 and on both sides of the cylindrical rod 44. The cylindrical rod 44 can be used to clamp and fix plastic products with arc-shaped inner or outer walls. Compared with the square structure of the L rod 43, the cylindrical rod 44 will not cause damage to the plastic products. The anti-skid pad can increase the friction with the plastic products and protect the plastic products and the claws 4 from friction damage.

[0032] Working principle:

[0033] The plastic product is placed on the placement plate 3, and the motor 5 drives the rotating disk to rotate. The rotation of the rotating disk cooperates with the arc groove 21 and the sliding rod 41, so that the claw 4 moves synchronously along the accommodating groove 31 on the placement plate 3 in the direction away from the center of the placement plate 3. When the claw 4 abuts against the plastic product, the spring 33 is deformed. Since the side walls of the plastic product are at different distances from the center, the claw 4 continues to move until each claw 4 abuts against the plastic product placed on the placement plate 3, thereby completing the clamping of the special-shaped plastic product with inconsistent side walls from the center; when the clamping is completed, the spring 33 restores and drives the claw 4 to move, and each claw 4 remains distributed in a ring on the placement plate 3 to clamp and fix the plastic product next time; and the claw 4 of the device can clamp and fix the plastic product through the inner wall or outer wall of the plastic product, the structure is relatively simple, no flipping is required, and it is easy to operate and maintain.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
