Description

Technical Field

[0001] This utility model relates to the technical field of sealing strip cutting and bonding, specifically to an auxiliary tooling for sealing strip cutting and bonding. Background Technology

[0002] Slewing bearings are a traditional type of slewing mechanism that plays a crucial role in the construction machinery industry. Before leaving the factory, slewing bearings require the installation of nitrile rubber sealing strips. Before installation, a fixed length of sealing strip must be cut, and then the ends of the strip are bonded together. Common methods include vulcanization bonding and manual bonding. Vulcanization bonding is more complex and is not currently suitable for bonding sealing strips of varying lengths for various non-standard parts. The commonly used manual bonding method—cutting the strip and then gluing the ends together—has the following drawbacks:

[0003] 1) The cutting surface is manually cut with scissors, resulting in uneven cuts that affect the bonding effect and lead to a high defect rate;

[0004] 2) Due to the thinness of the sealing strip, the cross-sectional area at the bonding point is small, making alignment difficult;

[0005] 3) After applying the adhesive, it takes time for the adhesive to cure, so manual pressing is required to wait for the adhesive to harden, which affects the processing efficiency.

[0006] Reference CN202221789979.1 describes a sealing strip cutting auxiliary tooling that uses a limiting groove to restrict the sealing strip and push it to achieve oblique cutting. However, it has a technical problem that the strip cannot be fixed and bonded after cutting.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example 1

[0049] Please see Figure 1-5 This utility model provides a technical solution. A sealing strip cutting and bonding auxiliary tooling includes a main frame 3; the main frame 3 is bent and has a horizontal sliding groove group and a vertical groove 31 respectively provided inside and outside; a fixed cutting block 2 and a moving block 6 are slidably installed in the horizontal sliding groove group;

[0050] A spring tool holder 4 is movably installed in the vertical groove 31; a cutting tool 5 is detachably installed under the spring tool holder 4, and the bottom of the cutting tool 5 is used for cutting the sealing strip 100 downward;

[0051] On one side of the fixed cutting block 2 facing away from the vertical groove 31, a first clamping groove 21 is formed; on one side of the moving block 6 facing away from the vertical groove 31, a second clamping groove 61 is formed; the first clamping groove 21 and the second clamping groove 61 are used for clamping the sealing strip 100; the width of the sealing strip 100 is not greater than the groove width of the first clamping groove 21 and the second clamping groove 61;

[0052] A first protrusion 22 is provided on the fixed cutting block 2, and a first groove 62 is provided on the moving block 6, and the first protrusion 22 and the first groove 62 are arranged facing each other; the cutting tool 5 is in a "Ji" shape, and the cutting tool 5 is movably inserted between the first protrusion 22 and the first groove 62; the bottom length of the cutting tool 5 is not less than the width of the sealing strip 100, and the bottom length of the cutting tool corresponds to Figure 1 the longitudinal length in, corresponding to the groove width direction of the first clamping groove; the axial direction of the clamping screw 1 is the horizontal direction; the depth of the vertical groove is vertical; that is, three coordinate directions are formed. It is specified that the bottom length of the cutting tool is not less than the width of the sealing strip, so as to ensure the cutting effect of the cutting tool and completely cut off the sealing strip in a single cut.

[0053] A set screw 9 is installed at the bottom of the moving block 6; a first threaded hole 23 is formed on one side of the fixed cutting block 2 facing away from the moving block 6, and a clamping screw 1 is threadedly connected in the first threaded hole 23.

[0054] The utility model completes the bonding of the joint 100 of the sealing strip to be installed through a cutting and bonding auxiliary tooling. The implementation method is as follows:

[0055] Determine the sealing strip of the standard length, and insert the sealing strip 100 into the first clamping groove of the fixed cutting block and the second clamping groove of the moving block; the moving block is tightened with a set screw upward, press the spring tool holder 4, and cut the sealing strip to form a "Ji" - shaped incision. The head and tail ends of the sealing strip of the standard length respectively form a fixed - end sealing strip and a mobile - end sealing strip.

[0056] Install the fixed - end sealing strip in the first clamping groove, install the mobile - end sealing strip in the second clamping groove and fix it with a set screw, apply glue on the incision surface, push the moving block, so that the fixed - end sealing strip and the mobile - end sealing strip are abutted, and start bonding the sealing strip. The two ends are contacted and pressed, and at this time, rotate the clamping screw to connect and tighten the fixed cutting end and the moving block, and directly place it and wait for the glue to cure.

[0057] The fixed cutting block and moving block of this utility model are both made of nylon, a material with adhesive-repellent properties that does not easily leave adhesive residue. Even if adhesive overflows during the bonding process, it will not significantly affect the usability of the fixture. Because the cutting blade has a Z-shaped edge, the notch in the cut sealing strip is stepped. Compared to a straight cut, the stepped notch has a larger contact area and a transverse bonding surface, which is more firmly bonded under shear force. The cutting blade is a consumable component and can be removed and replaced, ensuring the cutting efficiency of the fixture.

[0058] Example 2

[0059] like Figure 6-13 As shown, this is another embodiment of the present invention, based on Embodiment 1. Figure 7 As shown, the transverse chute assembly includes guide groove 1 32 and guide groove 2 33. The main frame 3 includes a vertical plate 34 and a transverse plate 35, which are integrally connected.

The structure of the cutting blade 5 is as follows: Figure 12 As shown, a mounting hole is made at the top, and the top plate and the cutter are connected by inserting a connecting slot and then by side mounting bolts.

[0063] like Figure 10 As shown, a fixing groove 36 is provided on the transverse plate 35. The body of the set screw 9 passes upward through the fixing groove 36 and is threadedly connected to the movable block 6. The fixing groove 36 is "L" shaped. The set screw can either extend upward into the clamping groove two to clamp the sealing strip, or move laterally along the fixing groove.

[0064] The movable block 6 has a second threaded hole 63 on the same horizontal line as the first threaded hole 23. The clamping screw 1 is used to thread the first threaded hole 23 and the second threaded hole 63, and thread the movable block and the fixed cutting block. The spacing can be determined to ensure that the bonding part does not shake. The cutting blade 5 does not interfere with the clamping screw 1. That is, when the cutting blade is cutting, it does not come into contact with the clamping screw, which prevents the cutting blade from being unable to cut.

[0065] Both clamping groove 21 and clamping groove 61 are located on the upper part of guide bar 8; guide bar 7, which fixes the top of cutting block 2 and moving block 6, has a strip-shaped groove 10 on the side opposite to the vertical groove 31, such as Figure 8 As shown, setting a strip groove on the fixed cutting block can achieve a stable guiding effect and save the mass of the fixed cutting block.

[0066] The top of the vertical plate 34 is provided with a horizontal part parallel to the horizontal plate 35, and the bottom of the horizontal part is provided with a strip 37; the strip 37 is adapted to the strip groove 10.

[0067] like Figure 8 and 9 As shown, a strip-shaped groove 11 is provided between the clamping groove 21 or clamping groove 61 and the guide bar 8; the side of the transverse plate 35 away from the vertical groove 31 is bent towards the vertical plate 34 and connected to the strip-shaped groove 11. A protrusion 22 is provided at intervals the same as the clamping groove 21; a limit strip 24 is provided on the lower protrusion 22.

[0068] Compared to Embodiment 1, this embodiment features guide groove one and guide groove two on the fixed cutting block and the moving block. These guide grooves, along with guide strip one and guide strip two, achieve a directional guiding effect, ensuring stable and predictable movement. Furthermore, the addition of guide groove one and guide groove two makes the guidance at both ends of the main frame more accurate.

[0069] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
