[0012] The inverted fixture's contact frame is set around the frame-shaped part of the workpiece to be processed, and an angle steel is provided on the inverted base plate inside the frame-shaped part. The contact frame and the angle steel provide limiting force to the inner and outer sides of the frame-shaped part.

[0013] The contact frames are arranged in several rows, with each row of contact frames parallel to each other.

[0014] The contact frame and the bottom angle steel of the contact frame limit the portion of the workpiece that is perpendicular to the outline of the rod.

[0015] The positioning frame extends out of the top of the contact frame and has a mounting part on the side of the positioning frame facing the contact frame, which is fastened to the top of the positioning frame.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] like Figures 1-7 As shown, the pick-and-place machine frame processing fixture of this embodiment is suitable for both forward and inverted positioning of the pick-and-place machine frame. It includes a forward fixture 6 and an inverted fixture 7. Both the forward fixture 6 and the inverted fixture 7 provide multi-point positioning of the workpiece to be processed in three-dimensional space.

[0031] The forward tooling 6 includes a forward base plate 601 and a stand 602 mounted on the forward base plate 601. A forward clamp 607 for holding the workpiece to be processed is mounted on the top of the stand 602. A clamping block 603 for abutting and limiting the workpiece to be processed is mounted on the forward base plate 601.

[0032] The inverted fixture 7 includes an inverted base plate 701 and an abutment frame 702 mounted on the inverted base plate 701. The top of the abutment frame 702 is provided with a positioning frame 703 for circumferentially limiting the end of the workpiece to be processed. An angle steel 606 is mounted on the inverted base plate 701. The angle steel 606 applies an abutment limit from the inside out to the frame-shaped part 1 of the workpiece to be processed.

[0033] The clamping and limiting forces applied to the workpiece by the forward tooling 6 and the inverted tooling 7 are both located in the horizontal plane.

[0034] The upright 602 of the forward tooling 6 is covered by the workpiece to be processed, providing the workpiece with a vertical upward support force.

[0035] The clamping and limiting forces applied by the forward fixture 607 and the clamping block 603 on the forward fixture 6 are located on the top and bottom surfaces of the fixture, respectively; the forward fixture 607 includes a locking pin 605, which abuts against and limits the workpiece to be processed.

[0036] The inverted fixture 7 has a contact frame 702 set around the frame-shaped part 1 of the workpiece to be processed. An angle steel 606 is provided on the inverted base plate 701 inside the frame-shaped part. The contact frame 702 and the angle steel 606 provide limiting force on the inner and outer sides of the frame-shaped part 1.

[0037] The contact frame 702 is arranged in several rows, and each row of contact frames 702 is parallel to each other.

[0038] The contact frame 702 and the bottom angle steel 606 of the contact frame 702 limit the portion of the workpiece that is perpendicular to the outline of the rod 2.

[0039] The positioning frame 703 extends out of the top of the contact frame 702 and has a mounting part 704 extending from the side of the positioning frame 703 facing the contact frame 702, which is fastened to the top of the positioning frame.

[0040] Locking pins 605 penetrate at least one set of opposite sides of the positioning frame 703, and the locking pins 605 abut against the workpiece to be processed.

[0041] The specific structure and working principle of this utility model are as follows:

[0042] This utility model provides reliable positioning for large parts with a closed frame and rod 2, such as a pick-and-place machine frame. The pick-and-place machine frame, as the part to be processed, has the following shape characteristics: Figure 1 As shown, the part includes a frame-shaped portion 1, with a chamfered corner forming an irregular pentagon that tends towards a rectangle. Two parallel rods 2 extend from this pentagon, located on the same side of the pentagon. The frame-shaped portion 1 and the rods 2 are located in the same horizontal plane, forming a coplanar portion. A support rod 3 is connected below the coplanar portion. The coplanar portion and the support rod 3 form a three-dimensional workpiece to be processed.

[0043] The machining fixture is required to limit both the inner and outer sides of the frame-shaped part 1, as well as the ends and sides of the rod 2. Additionally, it needs to limit the ends of the support rod 3. This embodiment provides a set of two tooling fixtures, forming a complete machining fixture, used to limit the workpieces placed upright and inverted, respectively.

[0044] The machining fixtures are divided into forward fixtures 6 and inverted fixtures 7.

[0045] The forward clamp 607 includes a forward base plate 601 and a stand 602 located on the forward base plate 601. The forward clamp 607 is installed on the top wall of the stand 602. The forward clamp 607 includes an integral clamping base block 604. The clamping base block 604 is recessed in the middle to form arm-shaped structures on both sides. Locking pins 605 pass through the arm-shaped structures on both sides respectively. The frame-shaped part 1 of the workpiece is abutted and limited by tightening the locking pins 605.

[0046] In addition to the forward clamp 607, the limiting structure at the rod 2 of the workpiece to be processed also uses angle steel 606 for auxiliary limiting.

[0047] The connection between member 2 and frame part 1 forms a right angle, and an angle steel 606 is added at the right angle. Both angle steel 606 and locking pin 605 are located at positions where angle steel 606 covers the locking pin 605 to reduce interference between components.

[0048] No additional limiting is applied to the middle section of member 2 to prevent excessive stress on member 2 from causing deformation. A positive clamp 607 is also provided at the end of member 2 away from the frame portion 1. The positive clamps 607 on adjacent members 2 are staggered. Member 2 also has a connecting rod 4 at its end, which is also equipped with a positive clamp 607. A single locking pin 605 is also provided at the end of the connecting rod 4 or member 2 for limiting.

[0049] At this point, the limiting of the coplanar portion is complete.

[0050] At the bottom end of the support rod 3, for this type of thin rod, each support rod 3 is equipped with two separate clamping blocks 603. Locking pins 605 pass through the clamping blocks 603 to clamp and limit the two sides of the bottom end of the support rod 3. The advantage of the separate clamping blocks 603 is that the installation position of the clamping blocks 603 on the front base plate 601 can be adjusted, making it suitable for support rods 3 of different specifications; and it facilitates subsequent installation. For example, after installing one clamping block 603 and placing the workpiece to be processed, the other clamping block 603 can be installed, reducing alignment difficulty.

[0051] It should be noted that the forward clamps 607 are all perpendicular to the contour edge they clamp.

[0052] The inverted fixture 705 includes an inverted base plate 701, on which an abutment frame 702 is mounted. The coplanar portion of the workpiece rests on the inverted base plate 701, and a support rod 3 is positioned close to the abutment frame 702. An angle steel 606 is mounted on the inverted base plate 701, abutting against the inner top corner of the frame-shaped portion 1. A positioning frame 703 is mounted at the top of the abutment frame 702, and locking pins 605 penetrate one set of opposite sides of the positioning frame 703. The bottom of the support rod 3 at the frame-shaped portion 1 of the workpiece rests precisely within the positioning frame 703, and is subjected to a relative locking force from one set of opposite sides of the positioning frame 703.

[0053] Since the positioning frame 703 needs to extend beyond the top surface of the contact frame 702, a mounting part 704 is extended from the positioning frame 703 and fixedly connected to the contact frame 702, thereby increasing the connection area between the positioning frame 703 and the contact frame 702 and improving the connection strength.

[0054] To facilitate the placement of the workpiece to be processed, the mounting part 704 can be fixed by post-installation.

[0055] The bottom of the support rod 3 of the rod 2 part of the workpiece is held by an inverted clamp 705 with the same structure as the forward clamp 607. Since the bottom of the support rod 3 of the rod 2 part is connected by a gusset plate 5, two sets of inverted clamps 705 are arranged in an array or symmetrically on the gusset plate 5. This reduces the use of clamping structures while ensuring that the smaller gusset plate 5 can be bidirectionally limited on both sides.

[0056] The advantage of this invention is that, for parts with a frame-shaped portion 1 and an extension rod 2, such as a pick-and-place machine frame, it can provide effective limiting for each weak point, preventing machining accuracy deviations caused by oscillation. At the same time, the inverted fixture 705 can limit the movement of gusset plates 5 of different lengths, thus improving applicability.
