Description

Technical Field

[0001] The present invention relates to an adaptive multi-dimensional adjustment and fixing device for an orbital dispensing machine. Background Art

[0002] In the prior art, the fixing device of the dispensing machine adopts a fixed jaw structure, which can only adapt to products of a single size. When changing products, it is necessary to redesign the fixture, resulting in high production costs and low efficiency. Moreover, it only supports the adjustment of the overall height and cannot independently adjust the height of a single jaw, resulting in uneven force on the product surface, poor fixing in some areas, and affecting the dispensing accuracy. The fixing effect on special-shaped products or products with uneven surfaces is poor, and it is easy to cause product shaking or glue overflow due to insufficient local pressing. For example, a position conversion fixture for dispensing processing disclosed in CN116060254A installs pressing devices on the front and rear sides of the end face of the fixing member, and the fixing member can rotate around the rod axis under the action of the driving device, but the position of the pressing device cannot be adjusted, so it can only process and fix products of a specified model.

[0018] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0019] An adaptive multi-dimensional adjustment and fixing device for an orbital dispensing machine; it includes a fixed base 1, an adjustment shaft 2, a jaw adjustment seat 3, and an elastic jaw 4; a shaft fixing hole 8 is machined on the side of the fixed base 1, and the adjustment shaft 2 is coaxially connected to the fixed base 1 through the shaft fixing hole 8 and is locked and fixed by a fixing screw 5; the adjustment shaft 2 is cylindrical, and multiple jaw adjustment seats 3 are axially installed on the adjustment shaft 2, and each jaw adjustment seat 3 is detachably connected to the adjustment shaft 2 by a fixing screw 5; an elastic jaw 4 is installed on the jaw adjustment seat 3. The fixed base is coaxially connected to the adjustment shaft through the shaft fixing hole 8 and is locked by the fixing screw 5 to form a stable foundation. Multiple jaw adjustment seats are installed on the adjustment shaft, and detachable connection is achieved through screws, allowing flexible adjustment of the clamping position along the axis. The elastic jaw is directly fixed on the jaw adjustment seat to provide clamping force. By making the jaw adjustment seat, the elastic jaw, and the fixed base into one module respectively, the detachable jaw adjustment seat supports quick replacement or addition and subtraction of clamping units to adapt to different workpiece requirements. The axial layout of the adjustment shaft combined with the tightening and loosening control of the fixing screws realizes multi-directional adjustment of the clamping position.

[0020] Furthermore, the elastic jaw 4 is an arc-shaped clamping piece, one end of which is fixed to the jaw adjustment seat 3 through a connecting plate 10, and the other end is provided with an elastic pressing head. The arc-shaped structure can increase the contact area with the workpiece, and the elastic pressing head provides an adaptive clamping force through its own deformation. The deformation characteristics of the elastic pressing head can adapt to workpieces of different shapes or sizes, reducing the risk of clamping damage, and contact stability: the arc-shaped design enhances the clamping fit and prevents the workpiece from sliding.

[0021] Furthermore, the connecting plate 10 is L-shaped, and several jaw fixing holes are provided thereon. The connecting plate 10 is attached to the rear end and the bottom of the jaw adjustment seat 3 and is fixed by bolts. The L-shaped connecting plate 10 is fixed to the rear end and the bottom of the jaw adjustment seat 3 by bolts, and the multiple jaw fixing holes thereon provide installation flexibility. The L-shaped structure disperses the stress during clamping and avoids local overload.

[0022] Furthermore, the jaw adjustment seat 3 is a right trapezoid with its inclined surface facing upward; a circular through hole is machined on the side of the jaw adjustment seat 3, and a fixing threaded hole connected to the circular through hole is machined at the upper base. The inclined surface design facilitates the adjustment of the clamping angle, and the through hole and the threaded hole cooperate with the fixing screw to realize the quick installation and positioning of the jaw adjustment seat.

[0023] Furthermore, one end of the fixed base 1 is fixed with a mounting plate, and two parallel mounting holes 7 are machined on the mounting plate. The mounting holes 7 are strip-shaped holes. Allowing the bolt to slide in the hole realizes the lateral fine adjustment of the mounting position.

[0024] Furthermore, a positioning boss is provided in the concentric circle mating groove of the fixed base 1, which matches the groove at the bottom of the adjusting shaft 2 to limit the axial displacement of the adjusting shaft 2. To ensure coaxiality, the mating of the boss and the groove eliminates axial offset and guarantees the rotation accuracy of the adjusting shaft.

[0025] A scale is provided on the adjusting shaft 2, and the accuracy of the scale ruler is 0.5 mm.

[0026] The fixing screw 5 is an internal hexagon screw, and an anti-slip gasket is provided at its end.

[0027] The bottom of the fixed base 1 is provided with an installation guide rail for moving with the orbital dispensing machine.

[0028] As Figure 1 shown, the base 1 and the adjusting shaft 2 adopt concentric circle mating, and the two are fixed together by screws 5. Loosen the screws 5, and the position and rotation angle of the adjusting shaft 2 can be adjusted to change the overall height of the clamping jaws. A plurality of clamping jaw assemblies are installed on the shaft 2 and are slidably connected to the shaft 2 through the clamping jaw adjusting seat 3. Each clamping jaw assembly includes a clamping jaw adjusting seat 3, an elastic clamping jaw 4, and a setscrew 6. Loosen the setscrew 6, and by adjusting the rotation angle of the clamping jaw assembly, the height of the end of part of the clamping jaws can be changed to adapt to products of different heights, and the distance between the clamping jaw assemblies can be adjusted to fix products of different sizes.

[0029] Example 1: Fixing of standard rectangular products

[0030] 1. Rotate the adjusting shaft 2 to adjust the overall height of the clamping jaws to 90% of the product thickness;

[0031] 2. Adjust the distance between the clamping jaw adjusting seats 3 so that the distance between the clamping jaws matches the product width;

[0032] 3. Individually fine-tune the angles of the respective clamping jaw adjusting seats 3 so that the elastic pressing head contacts the product surface and applies a pressure of 5 - 10 N.

[0033] Example 2: Fixing of special-shaped products

[0034] 1. Loosen the screws on the base and adjust the inclination angle of the clamping jaws to fit the product curved surface;

[0035] 2. By rotating the clamping jaw adjusting seat 3, compensate for the height difference in different regions to ensure uniform pressure of each clamping jaw.

[0036] Finally, it should be noted that: The above embodiments are merely examples given for clear illustration. The present invention includes but is not limited to the above embodiments, and it is not necessary and impossible to enumerate all the implementation manners here. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. All implementation manners that meet the requirements of the present invention fall within the protection scope of the present invention.
