Description

Technical Field

[0001] The utility model relates to the technical field of plastic parts processing, in particular to a locking tool for plastic parts processing. Background Art

[0002] Plastic parts processing, also known as plastic forming processing, is a general term for various processes for converting synthetic resins or plastics into plastic products. It is a larger production department in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. Plastic parts are widely used.

[0006] The support assembly comprises studs, nuts and a placement platform. The studs are in multiple groups and are locked on the support frame through nuts. The placement platform is fixed at the ends of the multiple groups of studs.

[0007] By adopting the above technical solution, plastic parts of different sizes can be quickly locked, with high adaptability and stable positioning.

[0008] The adjusting plate is provided with a notch, and the adjusting bolt is slidably arranged at the notch.

[0009] By adopting the above technical solution, the position of the adjusting bolt can be adjusted to adaptively position the plastic part.

[0010] The fixing plate is provided with a plurality of centripetally arranged notches, the length of the notches is greater than the diameter of the locking bolt, and the width of the notches is adapted to the diameter of the locking bolt.

[0011] By adopting the above technical solution, it is convenient to adjust the angle of the adjusting plate and press down and position the plastic part.

[0012] The width and length of the placement table are both less than the distance between two adjusting arms on the same side.

[0013] By adopting the above technical solution, it is convenient to adjust the angle of the adjusting arm without being affected by the placement table.

[0014] The adjusting arms and the adjusting plate on the same side together form a "冂"-shaped structure, and two adjusting arms on one side are arranged on the inner sides of the other two sides, so that the adjusting arms can swing normally.

[0015] By adopting the above technical solution, adjustment and positioning are carried out according to the plastic part.

[0016] The beneficial effects of the locking tooling for plastic part processing of the present utility model are as follows:

[0017] 1. According to the size of the plastic part, lock the stud on the support frame through the nut, place the plastic part on the placement table, drive the cylinder to push the corresponding adjusting arm to swing, and the adjusting arm can limit the edge of the plastic part through the adjusting plate. Adjust the positions of the two adjusting bolts on the adjusting plate, lock the adjusting bolts on the adjusting plate through bolts, and limit the plastic part from the corners of the other two sides of the plastic part to complete the positioning of the plastic part. For subsequent plastic parts of the same size, only directly drive the cylinder, push and pull the adjusting arm to limit and position the plastic part through the adjusting plate and the adjusting bolts, so as to achieve rapid positioning;

[0018] 2. By setting that the adjusting plate can be adjusted in angle between two fixed disks on the same side and locking the adjusting plate through the locking bolt, it is convenient to change the angle of the adjusting plate after the adjusting arm is lifted by a certain angle, so that the adjusting plate is adapted to the plastic part for positioning.

[0022] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0023] Referring to Figure 1-2 , a locking tooling for plastic part processing, including a base 1 and a locking mechanism and a support assembly installed on the base 1. The locking mechanism includes adjusting arms 6, a cylinder 7, an adjusting plate 8, adjusting bolts 9, a fixed disk 10, and locking bolts 11. There are four groups of adjusting arms 6, with two in each group facing both sides respectively, and they rotate on the base 1. The output end of the cylinder 7 is hinged to the adjusting arm 6 for driving the adjusting arm 6 to swing. The adjusting plate 8 is arranged between the two adjusting arms 6 on the same side. The fixed disk 10 is fixed to the end of the adjusting arm 6, and the locking bolt 11 passes through the fixed disk 10 and is threadedly connected to the end of the adjusting plate 8, so that the adjusting plate 8 can be installed on the fixed disk 10 through the locking bolt 11.

[0024] The support assembly includes stud bolts 3, nuts 4, and a placement table 5. There are multiple groups of stud bolts 3, and they are locked to the support frame 2 through nuts 4. The placement table 5 is fixed at the ends of multiple groups of stud bolts 3.

[0025] According to the size of the plastic part, first adjust the height of the placement table 5, and then lock the stud bolts 3 on the support frame 2 through the nuts 4. Then the plastic part can be placed on the placement table 5. After that, drive the cylinder 7 to push the corresponding adjusting arm 6 to swing, and the adjusting arm 6 can limit the edge of the plastic part through the adjusting plate 8. Then adjust the positions of the two adjusting bolts 9 on the adjusting plate 8 and lock the adjusting bolts 9 on the adjusting plate 8 through bolts to limit the plastic part from the corners of the other two sides of the plastic part, thus completing the positioning of the plastic part. For subsequent plastic parts of the same size, only need to directly drive the cylinder 7, push and pull the adjusting arm 6 to limit and position the plastic part through the adjusting plate 8 and the adjusting bolts 9, realizing rapid positioning.

[0026] It should be noted that the adjusting plate 8 can be adjusted in angle between the two fixed disks 10 on the same side and is locked through the locking bolt 11, so that after the adjusting arm 6 is lifted by a certain angle, the angle of the adjusting plate 8 can be changed to make the adjusting plate 8 adapt to the plastic part for positioning.

[0027] The adjusting plate 8 is provided with a notch, and the adjusting bolt 9 is slidably arranged at the notch. The adjusting arm 6 and the adjusting plate 8 on the same side together form a "冂"-shaped structure, and the two adjusting arms 6 on one side are arranged on the inner sides of the other two sides, so that the adjusting arm 6 can swing normally. The adjusting plate 8 is integrally arranged in a rectangular structure, and the adjusting bolt 9 can slide at the notch on the adjusting plate 8 to limit the corners of the plastic part according to the size of the plastic part, and the plastic part can be positioned after the adjusting plate 8 is pressed down.

[0028] The fixing plate 10 is provided with a plurality of centripetally arranged slots, the length of which is greater than the diameter of the locking bolt 11, and the width of which is adapted to the diameter of the locking bolt 11; according to the above arrangement of the slots, the locking bolt 11 can be inserted into the corresponding slots on the fixing plate 10 according to the adjustment angle of the adjusting plate 8, and the distance between the two locking bolts 11 can be adjusted, thereby locking the adjusting plate 8.

[0029] The width and length of the placement platform 5 are both smaller than the distance between the two adjustment arms 6 on the same side, so that the angle of the adjustment arm 6 can be adjusted without being affected by the placement platform 5 .

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
