Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

As shown in fig. 1 to 3, in the present embodiment, the bidirectional cam type angle clamp includes: base 100, sliding base 200, bidirectional cam 300, retaining member 400, and pressing table 500. In this embodiment, the base 100, the sliding seat 200, the bidirectional cam 300, the locking member 400 and the pressing platform 500 are all symmetrical structures, and the symmetry axes are overlapped on a straight line.

Fig. 4 is a schematic structural view of the base in the embodiment.

As shown in fig. 4, two fixing clips 110 are symmetrically disposed on both sides of the left end of the base 100, and the pressing edges of the two fixing clips 110 are perpendicular to the upper surface of the base 100. The pressing edges of the two fixing clamping plates 110 in the embodiment are both 90 degrees, that is, the two-way cam type angle clamp in the embodiment can be used for fixing two frames of 90. The edge pressing of the two fixing splints 110 can be set to other angles according to the actual fixing requirement. The base 100 has a central slot 120 in a central location. Also provided on the base 100 are two pairs of symmetrically disposed slide rails 140. As shown in fig. 2, the bottom surface of the base 100 has a base locking portion 130. In this embodiment, the base locking portion 130 is two base teeth symmetrically disposed on two sides of the central slot 110.

Fig. 5 is a schematic structural view of the slide holder in the embodiment.

As shown in fig. 5, the lower portion of the sliding seat 200 has two pairs of symmetrically disposed sliding grooves 230. The slide groove 230 is matched with the slide rail 140 of the base 100. The sliding guide 140 is embedded in the sliding groove 230, so that the sliding seat 200 is slidably connected with the base 100, and the sliding seat 200 is close to and/or far away from the fixed clamp plate 110. The sliding seat 200 is provided with oblong holes 210 at both sides, and the direction of the oblong holes 210 is perpendicular to the sliding direction of the sliding seat 200. The sliding seat 200 also has a limit sliding groove 220 on both sides.

Fig. 6 is a schematic structural view of the bidirectional cam in the embodiment.

As shown in fig. 3 and 6, the bidirectional cam 300 is embedded in the sliding seat 200. The bidirectional cam 300 has a rotation shaft 310, the rotation shaft 310 is disposed in the oblong hole 210, and a rotation surface of the bidirectional cam 300 rotates on the base 100. The reversible surface of the bidirectional cam 300 has a locking end 320 and an unlocking end 330. The locking end 320 is located farther from the center of rotation of the bidirectional cam 300 than the unlocking end 330. In this embodiment, the locking end 320 is a locking straight edge; the unlocking end 330 is an unlocking straight edge. The arrangement of the straight edges enables the locking position and the unlocking position of the bidirectional cam to be relatively stable. In addition, in this embodiment, the locking straight edge and the unlocking straight edge are both vertically arranged, that is, the bidirectional cam 300 can be switched between locking and unlocking by rotating 90 degrees. The bi-directional cam 300 has a cam wrench 350, the cam wrench 350 being disposed on the opposite side of the unlocking end 330 to facilitate the operator to rotate the bi-directional cam 300. In this embodiment, the unlocking end 330 has a feeding boss 340 to realize the double feeding function.

Fig. 7 is a schematic structural view of a locker in an embodiment.

As shown in fig. 7, retaining member 400 is of an inverted T-shape. The locking member 400 has a rotation hole 420 at an upper end thereof. The upper end of the locker 400 passes through the central groove 110 of the base 100 and is inserted into the bidirectional cam 300. The rotation shaft 310 of the bidirectional cam 300 passes through the rotation hole 420 of the locker 400 to accomplish the rotatable coupling of the bidirectional cam 300 with the locker 400. Locking teeth 410 are symmetrically provided at both sides of the lower end of the locker 400. Locking teeth 410 mate with the base teeth and when engaged, lock 400 locks with base 100.

As shown in fig. 3, the left end of the pressing platform 500 has two pressing edges perpendicular to each other, and the two pressing edges are respectively parallel to the pressing edges of the two fixing clamps 110. The bosses 510 are slid on both sides of the pressing stage 500. The sliding bosses 510 at the two sides of the pressing platform 500 are embedded into the limiting sliding grooves 220 at the two sides of the sliding seat 200, so that the pressing platform 500 is slidably connected with the sliding seat 200, can move along with the sliding seat, and is located between the fixed clamping plate 110 and the sliding seat 200. The right side of the pressing platform 500 is adjacent to the bidirectional cam 300, and the feeding boss 340 can be pressed against one side of the pressing platform 500 to drive the pressing platform 500 to feed towards the fixed clamping plate 110.

The working process of the bidirectional cam type angle clamp comprises the following steps:

the cam wrench 350 of the two-way cam 300 is rotated to the position shown in fig. 8, the unlocking end 330 of the two-way cam 300 is tightly attached to the base 100, and the rotating shaft 310 of the two-way cam 300 is located at the lowest end of the oblong hole 210 due to the short distance from the unlocking end 330 to the rotating shaft 310, as shown in fig. 9. At this time, the locking teeth 410 of the locker 400 are separated from the base teeth 130 of the lower end of the base, and the sliding base 200 can be arbitrarily slid on the base. The feed boss 340 rotates into the central slot 110 of the base 100 and is not effective.

A frame to be fixed is placed between the fixing splint 110 and the pressing table 500. The sliding seat 200 is pushed to the left, and the pressing table 500 is also moved to the left until the pressing table 500 presses the rim of the product. At this time, the right side edge of the sliding boss 510 of the pressing table 500 is attached to the stopper slide groove 220 of the slide holder 200.

Then, the cam wrench 350 of the bidirectional cam 300 is rotated clockwise to the position shown in fig. 10, i.e., rotated 90 degrees. The locking end 320 of the bi-directional cam 300 abuts the base 100. Since the distance from the locking end 320 to the rotation center of the bidirectional cam 300 is greater than that from the unlocking end 330, the distance from the rotation shaft 310 of the bidirectional cam 300 to the base 100 increases. At this time, the rotational shaft 310 of the bidirectional cam 300 moves upward in the oblong hole 210 to the position shown in fig. 1. Bidirectional cam 300 moves retaining member 400 upward and retaining teeth 410 of retaining member 400 engage and lock with base teeth 130 at the lower end of the base. At this time, the sliding seat 200 cannot move on the base.

There may be a gap between locking teeth 410 of locking member 400 and base teeth 130 at the lower end of the base or the locking position is not in a tangential engagement. Therefore, the feeding boss 340 of the bidirectional cam 300 further pushes the pressing table 500, so that the pressing table 500 is more closely attached to the product.

It should be noted that the position revolution surface opposite to the locking end 320 of the bidirectional cam 300 has no special requirement, and the working revolution surface is not affected to function.
