Description

Technical Field

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

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a larger production department in the plastics industry. In the process of plastic processing, clamping devices are often required to assist in processing and prevent plastic products from shifting during processing.

[0003] The specification of Chinese patent CN217914842U discloses an OK clamp parallel side top vise, including a fan-shaped push block, a first oblique block is arranged at the left end of the fan-shaped push block, and a second oblique block is arranged at the right end of the fan-shaped push block, which are matched with different jaws to make the clamping of heterogeneous workpieces more stable.

[0004] The Chinese patent CN214770500U specification discloses a double-head multi-piece fixture for a machining center, including a base, a P1 machining groove, a stopper, and a P2 machining groove. The workpiece is easily clamped and can perform multi-step machining on multiple workpieces, thereby improving machining efficiency.

[0005] When the existing clamping device for processing plastic products is used, the clamping tool and the fixture are in a separated state, resulting in the need to manually find the tool and operate it each time the clamping operation is performed, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when the existing clamping device for processing plastic products is used, the clamping tool and the clamp are in a separated state, resulting in the need to manually find the tool and operate it each time the clamping operation is performed, which is time-consuming, labor-intensive and inefficient.

[0007] In order to solve the above problems, the utility model provides a clamping device for processing plastic products, including a pallet table, a pair of side inclined blocks are symmetrically arranged on the upper end of the pallet table, a middle block is slidably connected between the two side inclined blocks, a through hole is opened at the upper end of the middle block, a circular slide groove is opened at the upper end of the middle block, a rotatable circle is rotatably connected to the inner end of the circular slide groove, the rotatable circle is located above the through hole, a locking screw is threadedly installed on the inner end of the through hole, an L-shaped vertical shaft is installed on the upper end of the locking screw, a sliding outer ring and a fixed outer ring are respectively arranged on the upper and lower sides of the outer end of the locking screw, and a folding ring is fixedly connected between the sliding outer ring and the fixed outer ring.

[0008] In the above-mentioned clamping device for processing plastic products, this solution connects the locking screw and the folding ring so that the L-shaped vertical axis is always fixed on the locking screw, which is beneficial for making the middle block and the side inclined block more efficient in clamping the clamped part.

[0009] As a further improvement of the present application, a stackable connecting rod is symmetrically fixedly connected between the rotatable ring and the locking screw.

[0010] As a further improvement of the present application, both left and right ends of the middle block are fixedly connected with convex strips, and one end of the side inclined block close to the middle block is provided with a slot.

[0011] As a further improvement of the present application, the card slot cooperates with the convex strip, and a clamping piece is placed on the upper end of the card board table.

[0012] As another improvement of the present application, one end of the two side inclined blocks that is away from each other is fixedly connected with a spacer side pad, and the spacer side pad is in contact with the part to be clamped.

[0013] As another improved supplement of the present application, locking rings are symmetrically provided on the upper end of the pallet table, and two locking rings are connected to corresponding locking screws.

[0014] As another improved supplement of the present application, the lowering outer ring is connected to the L-shaped vertical shaft, and the lowering outer ring and the fixed outer ring are rotatably connected to the locking screw.

[0015] In summary, this solution connects the locking screw and the folding sleeve so that the L-shaped vertical shaft is always fixed on the locking screw, which is beneficial to making the middle block and the side inclined block more efficient in clamping the clamped part. Specifically, the L-shaped vertical shaft presses down and compresses the folding sleeve so that the L-shaped vertical shaft is engaged with the threaded hole above the locking screw, and then the L-shaped vertical shaft is rotated to gradually thread the locking screw into the through hole on the middle block to complete the engagement with the clamped part. The stackable connecting rod is supported in a position between the fixed outer ring and the rotatable ring, so that when the L-shaped vertical shaft moves the locking screw upward, the locking screw can be supported and limited, which can make the operation process of the clamping device smoother.

[0029] Figure 3-7It is shown that the present scheme connects the locking screw 7 and the folding sleeve 10 so that the L-shaped vertical shaft 11 is always fixed on the locking screw 7, which is conducive to making the middle block 2 and the side inclined block 1 clamping the clamping member 13 more efficient. Specifically, the L-shaped vertical shaft 11 presses down and compresses the folding sleeve 10, so that the L-shaped vertical shaft 11 is engaged with the threaded hole above the locking screw 7, and then the L-shaped vertical shaft 11 is rotated to gradually screw the locking screw 7 into the through hole on the middle block 2 to complete the engagement with the clamping member 13, and the stackable connecting rod 6 is supported between the fixed outer ring 8 and the rotatable ring 16, so that when the L-shaped vertical shaft 11 moves the locking screw 7 upward, the locking screw 7 is supported and limited, which can make the operation process of the clamping device smoother.
