Abstract
Description
Technical Field
[0001] The utility model relates to the field of molds and fixtures, in particular to an inclined wedge and tongue mechanism module in the fixture. Background Art
[0002] Cylinders are widely used in fixtures, and the action of the cylinder output is used to clamp the workpiece. Common cylinders include linear cylinders and angle cylinders.
[0003] The clamping force of this type of fixture depends on the force that the cylinder can provide. This means that if you want to provide a greater clamping force, the specifications of the cylinder will be higher and the corresponding cost will be higher.
[0004] Large-sized cylinders are also large in size. If they are not properly arranged, they will occupy valuable clamping positions. Therefore, it is often impossible to simply apply cylinder products to a reasonable fixture. Utility Model Content
[0005] The problem to be solved by the utility model is to provide an inclined wedge and tongue mechanism module in a fixture, which is to add a set of inclined wedge groups to conventional linear power parts, and provide a reliable clamping mechanism suitable for the field of fixtures. The inclined force of the inclined wedge group can be used to increase the clamping force and change the clamping direction, so as to facilitate the subsequent manufacture of efficient fixtures.
[0006] In order to solve the above problems, the utility model provides a wedge-shaped tongue mechanism module in a fixture. In order to achieve the above purpose, the technical solution adopted by the utility model to solve the technical problem is:
[0007] The inclined wedge and tongue mechanism module in the fixture includes: a linear power part that outputs linear power; a tongue block that is used to contact and press the workpiece, and the movement direction of the tongue block itself is perpendicular to the movement direction of the linear power part; a wedge block group, including an active wedge block and a passive wedge block that are movably assembled using a linear groove, and the acute angle between the length direction of the linear groove and the movement direction of the linear power part is smaller than the acute angle between the length direction of the linear groove and the movement direction of the tongue block; the tongue block has a limiting hole, the active wedge block has a right-angled inner angle that bites the edge of the limiting hole opening, and the passive wedge block is assembled with the linear power part.
[0008] The beneficial effects of adopting the above technical solution are: this technical solution adds a set of inclined wedge groups to conventional linear power parts, providing a reliable clamping mechanism suitable for use in the field of jigs. The oblique force of the inclined wedge group can be used to increase the clamping force and change the clamping direction, thereby making it easier to make efficient jigs. It can be widely used in the field of precision 3C processing.
[0009] First, the oblique angle relationship of the linear groove determines that the force of the tongue block extending forward is greater than the original force of the linear power part. The linear groove ensures the limit guide and also ensures that only one linear mechanical degree of freedom is retained.
[0010] Second, the right-angle internal angle has a good bite effect with the edge of the opening, and has at least two contact surfaces, so the assembly between the passive wedge block and the tongue block is relatively stable and can withstand greater internal forces. The tongue block is not easy to loosen when repeatedly and long-term pressing the workpiece.
[0011] As a further improvement of the present invention, the projection of the active wedge along its own moving direction also passes through the limiting hole.
[0012] The beneficial effect of adopting the above technical solution is that the active wedge block can also pass through the limiting hole, so the forward extension distance of the active wedge block is longer, which expands the forming range.
[0013] As a further improvement of the utility model, along the direction away from the linear power part, the cross-sectional area of the active wedge block gradually decreases, and the cross-sectional area of the passive wedge block gradually increases; the active wedge block surface is integrally protruded with a dovetail tenon, and the linear groove is a dovetail groove recessed in the surface of the passive wedge block.
[0014] The beneficial effect of adopting the above technical solution is that the active wedge block and the passive wedge block are consistent in thickness from top to bottom after being matched, and their own volume and structural strength are fully utilized.
[0015] As a further improvement of the utility model, the front and back sides of the tongue block are respectively in contact with a sleeve plate and an outer cover plate, the outer cover plate has a wrapping pit, the wrapping pit wraps the tongue block, the tongue block located outside the wrapping pit is an exposed section of the tongue block in contact with the workpiece; the wrapping pit includes a lower opening and a side opening which are perpendicular to each other, the exposed section emerges from the side opening, and the lower opening is covered by the sleeve plate.
[0016] The beneficial effect of adopting the above technical solution is that the sleeve plate and the outer cover plate limit the movement of the tongue block in the direction of the linear power part.
[0017] As a further improvement of the present invention, the sleeve plate also has hollow holes for the active wedge block and the passive wedge block to pass through, and the projection of the limiting hole along its own penetration direction falls into the hollow holes.
[0018] The beneficial effect of adopting the above technical solution is that the hollow hole leaves space for the activity path.
[0019] As a further improvement of the present invention, the outer wall of the sleeve plate is provided with expansion arms extending in opposite directions.
[0020] The beneficial effect of adopting the above technical solution is that the expansion arm increases the installation area, making it easier to fix the sleeve plate to the external bottom plate.
[0021] As a further improvement of the utility model, the linear power member is a linear cylinder, and the output rod of the linear cylinder is fixed to the active wedge block.
[0022] The beneficial effect of adopting the above technical solution is that the linear cylinder responds relatively quickly.
[0023] As a further improvement of the utility model, the cylinder body of the linear cylinder is fixed to the sleeve plate by a sleeve member, and the sleeve member has a through cavity for accommodating the output rod, the active wedge block, and the passive wedge block.
[0024] The beneficial effect of adopting the above technical solution is that the sleeve piece plays a role of wrapping and protecting.
[0025] As a further improvement of the utility model, the inner wall of the through cavity has a first step surface perpendicular to its own through direction, and the side of the passive wedge block's right-angled inner angle that does not contact the inner wall of the limiting hole is a second step surface. The first step surface and the second step surface are parallel to each other, and the first step surface contacts one end of the passive wedge block.
[0026] The beneficial effect of adopting the above technical solution is that the first step surface limits the lowest limit position of the passive wedge block.
[0027] As a further improvement of the present invention, the outer wall of the sleeve member is prismatic, and both ends of the sleeve member are provided with flanges extending laterally outward, and the flanges are fixed to the cylinder body and sleeve plate of the linear cylinder.
[0028] The beneficial effects of adopting the above technical solution are: the prism shape ensures the rigidity of the sleeve member, and the flange ensures the assembly area. BRIEF DESCRIPTION OF THE DRAWINGS
