Description

Technical Field

[0001] This utility model belongs to the field of mechanical tool and supplies technology, and in particular relates to a tooling quick-change mechanism. Background Technology

[0002] Modern development places increasingly higher demands on the manufacturing industry. Currently, some production equipment often needs to produce different products on the same machine. When changing products, the tooling used also needs to be changed accordingly. Existing technology basically uses positioning pins to position and change tooling, and then locks it with screws. When changing products, the original tooling needs to be removed, and then the new tooling needs to be installed and locked again. This step-by-step process is very labor-intensive and time-consuming. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tooling quick-change mechanism, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tooling quick-change mechanism, comprising an anti-rotation block and a pressure ring. The anti-rotation block is installed in a groove at the upper end of the pressure head. The groove is formed by two interconnected parts: a square groove and a circular groove. The groove passes through the fixed end and extends downwards for a certain range. The anti-rotation block is fixed in the groove by connecting screws. The anti-rotation block includes an upper end face and an upper end face of the fixed end. The upper end face of the anti-rotation block is lower than the upper end face of the fixed end. The anti-rotation block has a protruding step. The upper end of the anti-rotation block uses a chamfered arc surface to facilitate the rotation of the pressure head and avoid collisions encountered during rotation.

[0005] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0006] A further technical solution: the pressure ring is mounted on the outer shaft of the pressure head, and the lower end face of the fixed end of the anti-rotation block is in contact with the step.

[0007] Further technical solution: The step includes an inclined surface and a side step, and the inner hole of the pressure ring is composed of two arc surfaces and two steps. When the quick-change mechanism is working, the pressure head rotates along the center of the pressure ring.

[0008] A further technical solution: Four countersunk holes are evenly distributed on the pressure ring, which are used to fix the quick-change mechanism in the corresponding positions.

[0009] A further technical solution: The pressure head shaft is provided with an inner hole, which is used to connect to other components that require quick-change functionality.

[0010] A further technical solution: The two cut surfaces formed by cutting the outer arc surface of the fixed end are smaller than the distance between the two inclined surfaces. When the cut surfaces and inclined surfaces are rotated to be parallel, it is beneficial to remove the pressure head.

[0011] Beneficial effects

[0012] This utility model provides a tooling quick-change mechanism, which has the following advantages compared with the prior art:

[0013] After aligning the entire quick-change mechanism through the inner hole of the pressure head, the pressure ring is fixedly installed on other components. At this point, rotating the pressure head causes the anti-rotation block to rotate as well. When the anti-rotation block reaches the side step, the side step prevents the pressure head from continuing to rotate, and the lower end face of the fixed end rests on the step. Under the limiting action of the step, the anti-rotation block is pressed against the pressure head, thereby limiting the pressure head. This process achieves the purpose of limiting the quick-change mechanism. Subsequently, the pressure head rotates back, and when the tangent is parallel to the inclined plane, the pressure head can be removed. This eliminates the need for bolts for fixing or locating pins for positioning, allowing for the installation and replacement of tooling. This greatly saves time for changing tooling, improves production efficiency, and effectively increases the production cycle and automation level of various assembly lines.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Specifically, the anti-rotation block 1 is installed in the groove 5 at the upper end of the pressure head 2. The groove 5 is formed by two interconnected parts: a square groove and a circular groove. The anti-rotation block 1 passes through the fixed end 17 and extends downwards to a certain extent. When removing the anti-rotation block 1, simply loosen the connecting screw and slide it out of the groove 5. During installation, the upper surface 8 of the anti-rotation block should be lower than the upper surface 9 of the fixed end to prevent excessive machining errors. The anti-rotation block 1 has a protruding step 4. The upper end of the anti-rotation block 1 is chamfered and has an arc surface 7, which is beneficial for cooperating with the rotation of the pressure head 2 and can avoid collisions encountered during rotation.

[0024] Specifically, the pressure ring 3 is mounted on the outer shaft 11 of the pressure head, the lower end face 10 of the fixed end is in contact with the step 4, and the inner hole 3 of the pressure ring is composed of two 12-circular arc surfaces, two 13-sloping surfaces, and two 6-side steps. When the quick-change mechanism is working, the pressure head 2 rotates along the center of the pressure ring 3. Four countersunk holes 15 are evenly distributed on the pressure ring 3, which are fixedly installed in the corresponding positions when the quick-change mechanism is in use.

[0025] Specifically, the inner hole 16 of the pressure head is connected to other components that require quick-change functionality. The two cut surfaces 14 formed by the outer arc surface of the fixed end 17 are smaller in distance than the distance between the inclined surfaces 13. When the cut surfaces 14 are parallel to the inclined surfaces 13, it is convenient to remove the pressure head 2.

[0026] In this embodiment of the utility model, after the entire quick-change mechanism is fitted together through the inner hole 16 of the pressure head, since the pressure ring 3 is fixedly installed on other components, when the pressure head 2 is rotated, the anti-rotation block 1 rotates accordingly. When the anti-rotation block 1 reaches the side step 6, the side step 6 prevents the pressure head 2 from continuing to rotate, and the lower end face of the fixed end 10 rests on the step 4. Under the limiting action of the step 4, the anti-rotation block 1 is pressed against the pressure head 2, thereby achieving the limiting of the pressure head. This process can achieve the purpose of limiting the quick-change mechanism. When the pressure head 2 rotates back and the tangent 14 is parallel to the inclined plane 13, the pressure head 2 can be taken out.
