Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a positioning tooling for processing non-ferrous metal alloy boxes. Background Technology

[0002] Non-ferrous metal alloy enclosures are metal structural components made by adding other alloying elements to one or more non-ferrous metals (such as aluminum, copper, magnesium, titanium, etc.) as the base material. They are widely used in aerospace, automobile manufacturing, electronic equipment, industrial equipment and other fields.

[0003] In the processing of non-ferrous metal alloy boxes, traditional positioning fixtures mostly achieve external clamping. In practical applications, excessive or uneven clamping force can cause the box workpiece to deform inward, which urgently needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for processing non-ferrous metal alloy boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for processing non-ferrous metal alloy boxes includes a base. A mounting bracket is slidably mounted on one side of the base via a convex rail. A T-shaped bracket is vertically mounted on one side of the mounting bracket. An adjusting screw is rotatably mounted inside the T-shaped bracket. A threaded collar is screwed to the lower part of the adjusting screw. The two sides of the threaded collar are rotatably connected to a slider via connecting rods. The slider is limited and mounted inside the bottom end of the T-shaped bracket. One end of the slider extends out of the T-shaped bracket and is connected to a push plate.

[0007] The base has fixing plates installed on both sides of its upper part. A screw rod is screwed into the middle of the fixing plate on one side, and a pressure plate is installed at one end of the screw rod.

[0008] In addition, a preferred structure is that the bottom wall of the T-shaped frame has a slot to fit the convex rail.

[0009] In addition, a preferred structure is that a slot is provided on the upper side of the mounting bracket for assembling the T-shaped bracket, and a locking bolt is screwed on the outer side of the mounting bracket, the locking bolt extending into the slot and pressing against the outer wall of the T-shaped bracket.

[0010] In addition, in a preferred structure, sliders are installed on both sides of the bottom of the T-shaped frame, and a rotating seat is fixedly installed on the upper part of the slider. The rotating seat is rotatably connected to the connecting rod through a pin, and the other end of the connecting rod is rotatably connected to the threaded collar through a pin.

[0011] Furthermore, in a preferred configuration, the bottom side of the adjusting screw is threaded and screwed to a threaded collar.

[0012] In addition, a preferred structure is that limit grooves are provided at both ends of the outer side of the T-shaped frame, and a connecting rod is installed in the limit groove for limiting.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, push plates are provided on both sides of the T-shaped frame. The push plates achieve horizontal displacement through a rotating adjusting screw and connecting rod mechanism. When the push plates are displaced and pushed out, they will press and support the inner wall of the workpiece, thereby offsetting the clamping force generated by the external pressure plate of the box, forming two forces in different directions to achieve a positioning effect and support the box wall panel. This effectively reduces the concave deformation of the workpiece wall panel and improves the positioning efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A positioning fixture for processing non-ferrous metal alloy boxes includes a base 1. A mounting bracket 2 is slidably mounted on one side of the base 1 via a convex rail 14. The mounting bracket 2 can move horizontally via the convex rail 14, thereby facilitating positioning to the middle of the box.

[0023] A T-shaped frame 4 is vertically installed on one side of the mounting frame 2. The vertical section of the T-shaped frame 4 is connected to the mounting frame 2, and the horizontal section faces downward.

[0024] The T-shaped frame 4 has an adjusting screw 42 rotatably mounted inside. The upper part of the adjusting screw 42 is a smooth section that extends out of the top of the T-shaped frame 4 and is equipped with a knob for manual rotation adjustment.

[0025] The bottom end of the adjusting screw 42 is rotatably connected to the bottom wall inside the T-shaped frame 4. A threaded collar 46 is screwed onto the lower part of the adjusting screw 42. The two sides of the threaded collar 46 are rotatably connected to the slider 411 through the connecting rod 44. The slider 411 is limited and installed inside the bottom end of the T-shaped frame 4. One end of the slider 411 extends out of the T-shaped frame 4 and is connected to the push plate 41.

[0026] The upper sides of the base 1 are equipped with fixing plates 11. A screw rod 12 is screwed to the middle of the fixing plate 11 on one side. A pressure plate 13 is installed at one end of the screw rod 12. Rotating the screw rod 12 will drive the pressure plate 13 to move through the spiral rotation, thereby realizing the clamping operation. This is easy to understand intuitively and will not be explained further.

[0027] The bottom wall of the T-shaped frame 4 has a slot to fit the convex rail 14.

[0028] A slot is provided on the upper side of the mounting bracket 2 for mounting the T-shaped bracket 4, and a locking bolt 3 is screwed on the outside of the mounting bracket 2. The locking bolt 3 extends into the slot and presses against the outer wall of the T-shaped bracket 4. The T-shaped bracket 4 is locked by the pressure friction to prevent slippage and to achieve height adjustment.

[0029] The bottom sides of the T-shaped frame 4 are equipped with sliders 411, and the upper part of the sliders 411 is fixedly equipped with a rotating seat 45. The rotating seat 45 is rotatably connected to the connecting rod 44 through a pin, and the other end of the connecting rod 44 is rotatably connected to the threaded collar 46 through a pin.

[0030] The bottom side of the adjusting screw 42 is threaded and screwed to the threaded collar 46.

[0031] Limiting grooves 43 are provided at both ends of the outer side of the T-shaped frame 4, and connecting rods 44 are installed in the limiting grooves 43 for limiting.

[0032] A baffle 15 is installed between the fixed plate 11 and the mounting bracket 2 to prevent machining debris from entering the cam rail 14.

[0033] In this embodiment, the lead screw 12 is rotated to drive the pressure plate 13 to move until the pressure plate 13 slightly clamps the surface of the non-ferrous metal alloy box workpiece placed on the base 1, thereby realizing the basic positioning operation.

[0034] Move the mounting bracket 2 according to the position of the box, so that the T-shaped bracket 4 moves to the upper middle part of the box. Then loosen the locking bolt 3 and adjust the height of the T-shaped bracket 4 appropriately, so that the bottom push plate 41 of the T-shaped bracket 4 enters the middle position of the box. Then tighten the locking bolt 3 to lock the height of the T-shaped bracket 4.

[0035] Then, the adjusting screw 42 at the top of the T-shaped frame 4 is rotated. The screw rotation drives the threaded collar 46 to move vertically downward. During the downward movement, the threaded collar 46 drives the connecting rod 44 to deflect. The connecting rod 44 converts the vertical displacement of the threaded collar 46 into the horizontal displacement of the slider 411. The slider 411 is deflected by the connecting rod 44 and extends outward. Then, the push plate 41 presses against the inner wall of the box, weakening and canceling the clamping force generated by the clamping plate 13, preventing the wall panel from deforming inward, and providing support for the box.

[0036] Then, by rotating the lead screw 12 again, the pressure plate 13 is fully clamped to complete the positioning and clamping operation of the box workpiece.

[0037] In its natural state, the mounting bracket 2 moves freely via the convex rail 14. After the push plate 41 presses against the box, the interaction force generated by the two causes the mounting bracket 2 to be unable to move.

[0038] The slider 411 moves horizontally through the internal channel of the T-shaped frame 4.

[0039] The thrust generated by the push plate 41 cancels out the clamping force of the pressure plate 13, effectively avoiding damage and deformation of the box caused by the single clamping force of traditional positioning fixtures.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
